Abstract

The single-walled spray gun container (202) has a paint-receiving section which is accessible mainly through two main apertures, and which has at least one supplementary access. This access can be closed by a valve which is located at least partly inside the supplementary access after this access has been closed.

Description

The invention relates to a single-walled spray gun cup having a paint receiving area substantially accessible through two main openings and having at least one additional access to the paint receiving area, the additional access being reclosable by means of a closure means. Such a cup is known from EP 678 334.

Spray gun cups are used in painting and serve to store a paint, so that during a painting enough paint on a spray gun is available.

The prior art discloses a multiplicity of spray gun cups which, inter alia, have partly different shapes but also different connection techniques in order to meet the most diverse requirements in the field of painting. For example, there are so-called gravity cups in which a stored paint agent flows into the spray gun substantially due to gravity. In addition, there are also so-called suction cups in which passes through selected Druckverhälmisse between spray gun cup and spray gun a paint even from the spray gun cup into the spray gun when the spray gun is held above the spray gun cup. Accordingly, such suction cups are usually arranged below the spray gun.

In addition to the large number of different Spritzpisrolenbechern exists at least one equally large variety of different ports with which the spray gun cup can be placed on a spray gun.

The known connections of the spray gun cups usually have a thread which communicates with a corresponding thread of a spray gun, so that a firm but detachable connection between the spray gun cup and the spray gun is made. The disadvantage of such threaded connections, however, is the relatively complicated attachment of the spray gun cup to the spray gun by means of a screwing movement.

To counteract this disadvantage, SpriLzpisLolenbecher already exist, which have at their terminals a very coarse thread, so that a spray gun cup can be attached to the spray gun with less than one revolution about its longitudinal axis. However, even this screwing is still expensive, since in this case the threads must be threaded.

But not only such an arrangement or removal of the spray gun cup on a spray gun is complex and thus time-consuming, but also the cleaning of a spray gun cup after a painting process of a first color. Often, a lot of time is spent for a color change in order to be able to continue a subsequent painting process with a different color. In particular, the interim cleaning and possibly changing a spray gun cup delay the painting considerably.

Even if the used spray gun cups are cleaned only after the actual painting process, the total duration of the painting is still disadvantageously high. Finally, every used spray gun cup must be cleaned of its color residues.

In addition to the cumbersome attachment of spray gun cups to spray guns prepare conventional spray gun cup also considerable disadvantages, since their openings, such as a pressure equalization port to equalize pressure within the spray gun cup during a painting process, so far can not be sealed tight enough. Due to this, it often happens that, despite the "closed" opening, the paint sprayer unintentionally leaves the spray gun cup. In addition, when opening such an opening, it is usually unintentionally that unnecessarily much of the coating agent leaves the spray gun cup into the environment when a closure of the opening has previously come into contact with the coating agent. For the above reasons, a spray gun cup must be handled carefully. This is obviously very time-consuming, since the complicated preparation of known spray gun cup paint preparation, but also the entire painting or the entire painting are additionally delayed.

From the non-prepublished WO 03/045575 A1 a double-walled spray gun cup is known, which has a cup insert as inner wall and a cup portion as outer wall, wherein the cup insert is inserted into the cup part.

The cup insert serves as a Lackiermittelaufnahme so that the paint does not come into contact with the outer wall of the spray gun cup and thus the outer wall of the spray gun cup is not contaminated with paint. As a result, a user a cleaning of the outer wall of the Sprirzpistolenbechers advantageously spared. The cup insert is designed as a thin-walled disposable component and is disposed of when not in use. Thus, a quick and easy color change to the spray gun is possible. Since the cup insert serves as a Lackiermiuelaufnahme and the paint is provided safely in the cup insert, the cup insert is closed with a corresponding lid.

The cup part serves to support the thin-walled designed cup insert, thus assumes a holding function with respect to the cup insert and thus forms an outer wall of the spray gun cup.

Only the cup insert as the inner wall of the spray gun cup is thus contaminated with paint and can be formed as a thin-walled disposable component, since the cup insert is supported by the outer wall of the spray gun cup.

Thus, the spray gun cup described is particularly well suited for a quick color change.

It is an object of the invention to develop known spray gun cup, so that in particular a color change can be made to a spray gun faster and more convenient.

The object of the invention is achieved by a single-walled spray gun cup having a paint receiving area substantially accessible through two main openings and having at least one additional access to the paint receiving area, the additional access being reclosable by means of a closing means and the closing minute during the closing of the additional Access is at least partially arranged in the additional access.

The term "additional access" for the purposes of the invention describes any secondary openings of a spray gun cup, which connect the Lackierrmittolaufnahmebercich the spray gun cup with the environment of the spray gun cup next to the two main openings. The additional access is therefore another opening of the spray gun cup. In particular, the term "additional access" means any secondary openings on a spray gun cup, in particular a single-walled spray gun cup, which provide either an air supply to the Lackiermittelaufnahmebereich and / or a refill of the Lackiermittelaufnahmebereichs for a paint. The Lackiermittelaufnahmebereich here describes the Spritzpistolenbecherinnere in which a Lackiermittel is stored.

The term "main opening" of a coating agent receiving area describes, on the one hand, a connection opening via which a coating agent passes from the coating agent receiving area to a spray gun. On the other hand, the term "main opening" describes a spray gun cup opening which is generally opposite this connection opening and via which, for example, a coating agent is filled into the spray gun cup or the paint agent receiving area of the spray gun cup is cleaned.

The additional access is structurally realized, for example, particularly simply by a material cut-out in a component delimiting the paint-receiving means. By such a closing of an additional access, it is now possible to securely close a single-walled spray gun cup so that a work preparation can be carried out much easier and faster. For example, in particular a spray gun cup, which works according to the gravity cup principle, can be set "upside down" during work preparation, for example when attaching to a spray gun or when attaching to an adapter. By means of the closure mechanism described above, it is ensured that no coating agent escapes from a closed air supply, which is located at the bottom when the spray gun cup is turned upside down. The term "bottom" here describes a state in which the air supply is located on the side facing the ground spray gun cup side. In addition, even mixing a two-component paint can be done easily in a spray gun cup. The use of the spray gun cup as a storage container for a paint or for Lackiermittelnreste is advantageously possible, since the additional supply in the present case is permanently closed securely. The particularly reliable closure of the single-walled spray gun cup takes place in the present case in that a closure means is arranged at least partially in the additional access of the coating agent receiving area. The fact that the closure means is at least partially disposed in the additional access, that protrudes into the additional access, is effectively prevented for the first time that larger amounts of a paint, which previously come into contact with the closure means is to get out of the Lackiermittelaufnahmebereich when the closure means is removed from the additional access.

The additional access is structurally particular safe and easy to close when the access has a channel In a first embodiment, this channel protrudes into the Lackiermittelaufnahmebereich, but he does not have it. In particular, if the present spray gun cup is also used as a mixing container, in which, for example, a two-component paint is mixed, it can be dispensed with that the channel protrudes into the Lackiermittelaufnahmebereich so as not to adversely affect a mixing device. Otherwise, such an intrusion is advantageous because the channel entrance of the access extends beyond the other inner cup boundary. As a result, the risk is reduced that the channel entrance is in a spray gun cup placed upside down directly with a paint, in particular with a Lackiermittelrest in contact. Thus, it is prevented that a paint on the basis of a capillary effect in the access or in the channel passes. This is particularly advantageous when the present spray gun cup is used permanently as a storage container, since on the one hand prevents a paint on the additional channel exits through a capillary effect to the outside, and on the other hand, the risk of drying of the paint in the gap between the Closure means and the additional access is reduced. Thus, it is avoided that the plug in the additional access by a drying paint "sticks" and is no longer or very difficult to remove

It will be appreciated that the additional access may be provided by almost any opening of the single-walled spray gun cup connecting the paint receiving area to the outside of the single-walled spray gun cup. It has been found that, in particular, a cylindrical or a conically extending channel cross section: represents an additional access which is particularly easy to close. As a result, the channel forms a kind of tube in which the Vecschtussmittel is introduced. Thus, the additional access is closed very safe.

In this context, it is advantageous if the closure means has a sealing plug which corresponds to the channel. If the sealing plug closes the additional access, the sealing plug is arranged in the channel such that it projects at least partially into the channel. Thus, the additional access is closed very safe. It is understood that the additional access can also be closed by differently shaped closure means which are arranged within the additional access. For example, at this point, attention should be drawn to the possibility of arranging a slide within the additional access in order to close it.

A variant embodiment provides that the closure means has an outer diameter which substantially corresponds to an inner diameter of the channel. This is on the one hand a simple insertion ensured the sealing plug into the channel. On the other hand, the channel is closed particularly well by the closure means, since in this case a kind of press fit is realized between the closure means and the channel

A particularly intimate connection between the closure means and the walls of the access is realized when the closure means has a slightly larger outer diameter than the inner diameter of the channel. In order for the closure means to be relatively easy to insert into the channel, it is advantageous if the closure means is made of a material which is different from a material from which the access is made.

A further embodiment provides that the additional access terminates with an outer boundary of the single-walled spray gun cup or lies behind the outer boundary. Such additional with the outer boundary final or behind the outer boundary of the spray gun cup back additional access makes it possible that the single-walled spray gun cup on its surface has no undesirable protruding or protruding components. This is particularly advantageous in areas of the single-walled spray gun cup, which form a footprint with which the single-walled gasoline gun cup is placed on a base, for example during work preparation for mixing or during a painting process for refilling a paint.

A preferred embodiment provides that the single-walled spray gun cup has on a first side a connection for arranging the single-walled spray gun cup on a spray gun, and the additional access is arranged on a side facing away from the connection of the single-walled spray gun cup. The arrangement of the additional access to the side facing away from the terminal is vorteihaft, since the additional access in the use of the single-walled spray gun cup in terms of a flow cup is excellent as air supply to the Lackiermittelaufnahmebereich the single-walled spray gun cup. It is understood that regardless of this, the additional access may be provided at almost any location of the single-walled spray gun cup, depending on the type of execution of the single-walled spray gun cup. Since the single-walled spray gun cup can be closed particularly securely by means of the closure means arranged at least partially in the additional access, as already explained above, the present single-walled spray gun cup is also particularly well suited for use as a storage container for a coating agent. In order to further secure the placement of the closure means in the access channel, the channel preferably has a length which is greater than the wall thickness of a spray gun cup wall. By such a length, the closure means within the channel advantageously much better supported, so that the risk of unintentional release of the closure means is reduced from the channel.

If a paint has previously been in contact with a portion of the additional access in the paint receiving area, it is particularly advantageous that only a very small portion of the paint passes outside the paint receiving area upon removal of the closure from the additional access, if any. This is due to the fact that the closure plug with the coating material advantageously comes into contact only on its front side facing the coating agent receiving area. Thus, the risk is reduced that unnecessarily much Lackiermittel adheres to the closure means, which comes on removal of the sealing plug from the additional access, so when pulling the Vemrblumstopfens from the supply channel outside the single-walled spray gun cup. This is not the case with conventional closure mechanisms of a single-walled spray gun cup. Rather, openings of a conventional single-walled spray gun cup are closed only with a lid or a cap, to which or to which a relatively large amount of a paint can adhere. This amount of paint passes so far when opening a conventional closure in the vicinity of the spray gun cup, so that the risk is relatively large that the environment is contaminated with this amount of paint accidentally. As a result, painting can be adversely affected. Such an unwanted leakage of a paint is often due to the fact that a cap on a border of an opening are only such hangs that parts of the cap surround this border from the outside and thus indeed a relatively secure contact between the cap and the edge of the opening is made , However, the side of the cap facing the paint-applying agent comes into contact with the coating agent over a large area, so that when the cap is lifted off the opening, the coating agent still adhering to the inside of the cap passes into the surroundings of the spray-gun cup.

This is prevented in the present case, since the closure means closes the additional access not only from the outside, but is arranged on the one hand directly in the additional access, whereby a particularly secure closing of the additional access is ensured. On the other hand comes the closure means, which is located directly within the access, only with its "small" face with the paint in contact. The term "small" here describes an end face of the closure means, which has a diameter which substantially corresponds to the inner diameter of the additional access. This is not the case with conventional closures, as they do not close access of a secondary opening within the access or are not located within the access but only cover an access opening.

A further simplification in terms of a quick color change is when the single-walled spray gun cup has at least one lid, preferably two lids, for closing the single-walled spray gun cup.

In this variant, the single-walled spray gun cup has, on the one hand, a first upper lid, which is attached to a side of the one-handed spray gun cup which faces away from the spray gun. On the other hand, the single-walled spray gun cup has a further lower lid which is arranged on a side of the single-walled spray gun cup facing the spray gun.

By the first upper lid and by the other lower lid of the single-walled spray gun cup can be completely closed, so that it can be advantageously used as a storage container for a Lackiermittel when needed. It is thereby possible that a plurality of single-walled spray gun cups filled with different coating agents are provided before or during a painting operation, so that a color change on the spray gun can be made particularly quickly hereby.

It has been found that it is advantageous if at least one of the lids has the additional access or a similarly closable passage. In order to be able to provide the single-walled spray gun cup in a short time ready for use, it is particularly advantageous if such a reclosable passage is provided on the first upper lid. This closable passage, for example, initially closed when the single-walled spray gun cup is provided with a filled therein paint. If the single-walled spray gun cup and the paint agent filled therein are required for the painting process, the further lower lid is first removed from the single-walled spray gun cup, so that the single-walled spray gun cup can be arranged with this opening on a spray gun.

For ease of attachment, the single-walled spray gun cup, as will be described below, have a latching connection, which also makes it possible to attach the single-walled spray gun cup straightforward and in no time at a corresponding receptacle.

Subsequently, the resealable passage is opened at the first upper lid, so that it comes in the interior of the single-walled spray gun cup during removal of the paint to a pressure equalization by subsequent flow of air

The term "lid" essentially describes a structure with which the single-walled spray gun cup is closed in such a way that a coating agent located in the single-walled spray gun cup does not escape from it unintentionally. Both the first upper lid and the further lower lid of the single-walled spray gun cup thus constitute a closure for the single-walled spray-paint cup with which it can be completely closed. It is understood in this context that the two lids are fastened by different techniques to the single-walled spray gun cup. For example, the lid can be screwed. Preferably, however, the lids are simply clipped onto an edge of the single-walled spray gun cup.

An embodiment variant provides that at least one cover is molded onto the single-walled spray gun cup. As a result, a possibility is created, the lid always attached to a single-walled spray gun cup, so that the risk of accidental misplacement of a lid is excluded.

It is understood that in addition to the molded lid, other connection options between the lid and single-walled spray gun cup can exist. For example, a lid is glued over a correspondingly long tab on the single-walled spray gun cup

The term "reclosable passage" may be provided by a simple hole in the form of a cutout in the lid. Ideally, this hole is already provided during the actual injection process of the lid.

However, in order to reduce the risk that a paint agent inadvertently passes from the interior of the single-walled spray gun cup through the re-closable passage into the environment when opening the reclosable passage, it is advantageous if the reclosable passage has a collar which at least at one of properly the single-ended spray gun cup arranged lid protrudes into the single-walled spray gun cup.

In this context, it is advantageous if the collar of the reclosable passage substantially perpendicular to its diameter has a height which is greater than the material thickness of the lid. In particular, this unintentional leakage of the paint from the interior of the single-walled spray gun cup on the resealable passage is very limited or even completely prevented.

In addition, such a collar gives the lid improved stability, allowing the lid can be placed faster on the single-walled spray gun cup.

In order to further reduce the risk of unintentional leakage of paint, it is advantageous if either the additional access has a conical channel or a reclosable passage of a lid has a tapered collar. By means of the conically extending collar, the resealable passage undergoes a rejuvenation, so that the risk of unintentional leakage of a coating agent is further reduced. The terms "additional access" and "reclosable passage" are used synonymously in the context of the invention. In the present case, if a secondary opening is arranged directly in a spray gun cup, the secondary opening is preferably designated by the term "additional access." However, if the secondary opening is located in a cover of the spray gun cup, it is preferably referred to as a "reclosable passage".

A preferred embodiment of the invention in this context provides for the resealable passage to taper in the direction from a passage opening facing the cover to a passage opening facing away from the cover.

A preferred embodiment provides that at least one lid has a depression and in the sink a resealable passage is arranged. Fortunately, the drain allows pre-centering of a closure when closing the reclosable passage. As a result, for example, a particularly narrow region of a plug can be introduced much easier into the reclosable passage.

As a result, the closing of the resealable passage considerably simplified, so that a change of color on a spray gun can also be made much easier and faster.

In general, it has been found that it is advantageous if an inner diameter of a passage opening facing away from the cover is less than 80% or less than 50%, preferably less than 30%, of the inner diameter of a passage opening facing the cover. By virtue of such a larger inner diameter, it is possible, in particular, to attach a closure to the closable passage simpler and thus faster, and thus to advantageously close the inner diameter of the passage opening facing the cover.

Accordingly, if this advantage is to be transferred to a lid with a sink, it is advantageous if an inner diameter of the closable passage is less than 80% or less than 50%, preferably less than 30%, of the inner diameter of the sink.

As mentioned above, a plug is needed to close the sealable passage. Accordingly, it is advantageous if the closable passage has a plug.

In order to be able to insert the stopper into the closable passage in a particularly simple and thus particularly rapid manner and to ensure that as little paint agent as possible from the interior of the single-walled spray gun cup enters the environment of the single-walled spray gun cup when opening the closable passage, it is advantageous in that the plug can be arranged both in the sink and in the closable passage.

Moreover, it is advantageous if the plug has different diameters. Preferably, the different diameters of the plug correspond to those inner diameters of the sink and the reclosable passage, respectively, so that the plug can be easily inserted into the reclosable passage.

In order to reduce the risk of loss of the plug, it is advantageous if the lid has a nipple on which a plug for closing the passage can be arranged.

Alternatively, the plug may be molded onto the lid. Thus, the lid of the single-walled spray gun cup and the plug of the lid can be made particularly inexpensive.

Cumulatively, it is advantageous if at least one cover is molded onto the single-walled spray gun cup. In order to reduce the risk of loss of a spray gun cup lid, it is advantageous if the lid is arranged from the outset on the single-walled spray gun cup.

It should be mentioned at this point that the features with regard to the lids of the single-walled spray gun cup are advantageous even without the other features of the invention, since a rapid color change on a spray gun can already be made by these features alone. In particular, it is only possible by the cover described here to use a single-walled spray gun cup as a storage container for a paint or mix in this two-component paint.

A color change on a spray gun is also greatly simplified and thus accelerated when a connection of the single-walled spray gun cup to a recording of a spray gun is latched fastened.

Due to the latching attachment option, the single-walled spray gun cup can be attached to a spray gun, so that a change of the single-walled spray gun cup can be made particularly quickly and conveniently. In this way, for example, a color change during a painting process can be made very quickly, so that different colors can be brought very quickly one behind the other onto a surface.

In addition, a latching connection is also advantageous when the single-walled spray gun cup is removed as a disposable product, since less stringent manufacturing requirements must be placed on a latching connection than is the case, for example, with a threaded connection. Thus, the production costs for a single-walled spray gun cup with a latching connection are lower than with an elaborately manufactured connection.

Such a locking connection is structurally particularly easy realized when the terminal has a spring and / or a groove.

For the purposes of the invention is meant a "spring" a structure which in a proper attachment of the single-walled spray gun cup to a recording partially or wholly in one envisaged device locks. Such a spring can be realized for example by one or more "noses" or "rings". In this case, the spring can form a physical unit with the connection or can be realized by an additional component which is arranged on the connection. For example, such an additional component, which may form a spring in the context of the invention, a simple O-ring, which is releasably but firmly arranged on the latching connection of the single-walled spray gun cup.

Alternatively or cumulatively, the latching connection of the single-walled spray gun cup can also have a groove into which a component fully or partially engages when the single-walled spray gun cup is properly attached to a receptacle.

The spring and groove described above need not necessarily be circumferentially mounted on the latching terminal, but may be provided only partially at the terminal. A circumferential spring and / or groove, however, are advantageous because this allows the single-walled spray gun cup can be mounted in almost any position to a corresponding receptacle.

For the purposes of the invention, the term "recording" designates in particular an area of a spray gun or of another component, such as an adapter, on which the single-walled spray gun cup is arranged when used properly.

To make the locking connection particularly safe, it is advantageous if the connection of the single-walled spray gun cup is at least partially encircled by a web. A firm connection can be made particularly well in the present case by a notch of the web. It does not matter whether the connection, as usual in the market, with a thread, it is an external thread or an internal thread, provided or not.

A further embodiment provides that the web completely umkragt the connection in order to produce a particularly good connection between the single-walled spray gun cup and the spray gun after the connection of the connection.

In this context, it is advantageous if the web is annular, preferably concentric, arranged around the connection.

Preferably, the web is made of an elastic material, so that the web over other components has a certain flexibility and thereby the spray gun cup can be particularly easily attached to a Spritzpistotenaufbahme.

Since such a connection has an advantageous effect on a color change on a spray gun, the features relating to this snap-fastened connection are advantageous even without the other features of the invention.

In order to realize a rapid color change in conjunction with a disposable spray gun cup, it is advantageous if the single-walled spray gun cup has a different wall thickness along its longitudinal axis.

An advantageous Ausfuhrungsvnriante provides that the single-walled spray gun cup on its spray gun side facing a greater wall thickness than on its side facing away from the spray gun.

Due to the large wall thickness selected on the spray gun side facing the single-walled spray gun cup gets such a good basic strength that the single-walled spray gun cup on its side facing away from the spray gun can easily have a much smaller wall thickness. Due to the lower wall thickness of the material consumption is reduced, so that such a single-walled spray gun cup is much more economical to produce In addition, the environment is less heavily burdened.

In this context, it has been found that it is advantageous for the single-walled spray gun cup to have a wall thickness of less than 3 mm or less than 1.5 mm, preferably less than 0.5 mm, in the region of its smallest material thickness.

In addition, it has been found that the single-walled spray gun cup advantageously has a wall thickness of more than 0.4 mm, preferably more than 1.5 mm, in the region of its greatest material thickness. By such a choice of a wall thickness of the single-walled spray gun cup receives a sufficiently high basic strength, so that the handling of the single-walled spray gun cup remains safe despite the sometimes small wall thickness. This is particularly vorreilhaft to secure the single-walled spray gun cup reliable on a recording.

The features with respect to the different wall thicknesses of a spray gun cup are advantageous regardless of the other features of the invention.

In order to arrange the present single-walled spray gun cup on conventional spray guns and to ensure a quick color change with respect to the use of conventional spray guns, it is advantageous if the single-walled spray gun cup has an adapter which can be arranged on the single-walled spray gun cup latching.

The adapter has on a first side a receptacle for the connection of the crirnungsungsgemäßen single-ended spray gun cup and on one of these first side opposite side of a port which communicates with the connection of the single-walled spray gun cup. Through the use of such an adapter, the single-walled spray gun cup can be produced particularly advantageously as a universal component, which can be attached to any conventional spray gun.

It has been shown that when using an adapter, a color change to a spray gun in addition much easier and can be made faster, if the adapter has a first receiving area for a single-ended spray gun cup and another receiving area for a spray gun and the first receiving area with hinged to the other receiving area.

In particular, by virtue of the fact that the first receiving area and the further receiving area are connected to one another in an articulated manner, the single-walled spray gun cup can be arranged quickly and conveniently on a spray gun even if the intake of the spray gun is not optimally arranged with respect to the connection of the single-walled spray gun cup. In addition, there is the advantage that a single-walled spray gun cup arranged by means of the articulated adapter on a spray gun can be aligned much better during painting work, so that in this case the risk is reduced that a coating agent unintentionally passes out of the closable passage of the lid. Rather, advantageously, the single-walled spray gun cup can be aligned much more flexible with respect to the spray gun by means of the articulated adapter, so that a connection between the two components can be made faster.

In order to securely seal the hinged adapter at the interface between the first receiving area and the other receiving area with respect to a paint, it is possible to edit the adapter at this interface very carefully and to continue.

A structurally particularly simple embodiment variant advantageously provides that an additional paint line, preferably a flexible hose, is arranged between the first receiving area and the further receiving area. Due to the additional paint line need not be particularly high demands on the production of the articulated interface between the two receiving areas, since the paint passes from the spray gun cup at least in the region of the rotary joint on the additional Lackiermittelleitung to the spray gun.

In this context, it is possible that the additional Lackiermittelleitung is located in the region of the rotary joint outside the adapter. In order to protect the additional Lackiermittelleitung especially from mechanical wear or mechanical damage, it is advantageous if the additional paint supply line in the region of the rotary joint is arranged substantially inside the adapter

For the sake of completeness, it should be mentioned at this point that the features with regard to the articulated adapter are also advantageous independently of the other features of the invention, since the articulated adapter additionally promotes a rapid color change on a spray gun and also the flexibility of the single-walled spray gun cup on many levels elevated.

With a method for producing a lid for closing a single-walled spray gun cup and / or a spray gun cup insert in which the lid and a plug of a closable passage of the lid are releasably produced from each other in a single Spritzgießvoreang, on the one hand, the manufacturing costs can be significantly reduced because in one Operation several components of the spray gun cup can be produced.

In addition, the risk is reduced that a plug for the closable passage of the lid is inadvertently lost, since the plug is connected directly to the lid and thus forms a unit with the lid

It is understood that the aforementioned features are not only advantageous for the single-walled spray gun container described, but that the features are individually or mutually combined with respect also a Spritzpistolenbechereinlage, which is arranged in a spray gun cup, are advantageous. The features described with the single-walled spray gun cup also achieve advantages with respect to a spray gun cup insert which are identical or at least similar to the achievable advantages of the single-ended spray gun cup described here.

Further advantages, objects and features of the present invention will be described with reference to the following explanations attached drawing, in which, for example, several single-walled spray gun cup are shown.

FIG. 1 shows an arrangement 100 with a spray gun 101 and a single-walled spray gun cup 102, wherein the two components 101 and 102 are connected to one another by means of an adapter 103. For this purpose, the adapter 103 is screwed to a receptacle 104 of the spray gun 101.

The adapter 103 also has a receptacle 105 onto which the single-walled spray gun cup 102 with its side 106 facing the spray gun 101 is clipped to the spray gun cup receptacle 105 of the adapter 103.

If the single-walled spray gun cup 102 is not disposed on the spray gun cup receptacle 105 of the adapter 103 or on the receptacle 104 of the spray gun 101, a small, first opening 107 of the single-walled spray gun cup, which is located on the side 106 facing the spray gun 101, by means of a small, first lid 108 are completely closed. For this purpose, the small, first cover 108 is at least partially slipped over the side 106 facing the spray gun 101. As a kind of "captive", the small, first lid 108 is attached to the single-walled spray gun cup 102 by means of a tab 109. The tab 109 is molded onto both the first, small lid 108 and the single-walled spray gun cup 102.

In addition, since the single-walled spray gun cup 102 has a large opening 110, the one-handed spray gun cup 102 includes a correspondingly large second lid 111. The large opening 110 is located on a side 112 facing away from the spray gun 101.

The large, second lid 111 is simply clipped onto an upper edge 113 of the single-walled spray gun cup 102 in this embodiment.

The large, second lid 111 has in its center a closable passage 114, via which a pressure equalization is established during a painting process between the spray gun cup inner 115 and an environment 116. The spray gun cup interior 115 is a paint receiving area of the spray gun cup 102 in which a paint agent is stored within the spray gun cup 102.

In addition, the closable passage 114 on its side facing the spray gun cup interior 115 side 117 comprises a collar 118 which has a conical shape.

In order to be able to close the resealable passage 114 in such a way that a coating agent 239 (see FIG. 2) does not pass through the passage 114 from the spray gun interior 115 into the environment 116, the large second cover 111 has a plug 119.

The plug 119 also has a conical shape, so that the plug 119 adapts to the conical shape of the closable passage 114 and thus can be arranged well in the closable passage 114.

In order that the plug 119 is not accidentally lost, the plug 119 is attached to the lid 111 by means of a plug holder 120. Here, the plug holder 120 is molded on both the plug 119 and the large second lid 111, so that the large second lid 111, the plug 119 and the plug holder 120 have been manufactured in an injection molding process.

The single-walled spray gun cup 202 shown in FIG. 2 has a latching connection 230, on whose lateral surface 231 a sealing ring 232 and a first guide ring 233 and a second guide ring 234 are arranged. With this latching connection 230, the single-walled spray gun cup 202 is attached to a spray gun cup receptacle 104 of a spray gun 101 (see FIG. 1). By the sealing ring 232 and the first guide ring 233 and the second guide ring 234 of the latching port 230 of the single-walled spray gun cup 202 with the receptacle 104 of the spray gun 101 (see Figure 1) is clamped such that the single-walled spray gun cup 202 is fixedly connected to the spray gun 101 ,

In order to additionally secure this fixed connection, the single-walled spray gun cup 202 has a peripheral web 235, which is arranged directly on the single-walled spray gun cup 202 and forms a physical unit with the single-walled spray gun cup 202. Therefore, the circumferential ridge 235 and the single-walled spray gun cup 220 are made in one piece.

In addition, the circumferential ridge 235 is located in the immediate vicinity of the latching terminal 230 around and has on its the latching terminal 230 side facing 236 a circumferential spring 237, which is suitable, in a corresponding groove (not shown here) of a spray gun 101st (see Figure 1) lock. In order to facilitate such engagement of the rotating spring 237, the circumferential web 235 is made of an elastic material, from which in the present embodiment, the entire single-walled spray gun cup 220 is made.

In the interior 215 of the single-walled spray gun cup 202, a screen 238 is arranged in front of the latching connection 230, so that a cup content 239 is filtered before it leaves the single-walled spray gun cup 202.

If the single-walled spray gun cup 202 is not arranged on a spray gun receptacle 104, the smaller opening 207 of the single-walled spray cup 202 can be closed by latching the latching port 230 with a lid 308 (see FIG. 3).

On the latching connection 230 opposite side 212 of the single-walled spray gun cup 202, a resealable large lid 211 is also arranged latching on the edge 213 of the single-walled spray gun cup 202, so that the single-walled spray gun cup 220 can be completely closed on this side 212. In order for air to be able to flow into the interior of the cup 215 when the cup contents 239 are removed, the resealable lid 211 has a plug 219 which closes a closable passage 214.

The closable passage 214 has a collar 218 which protrudes into the spray gun cup interior 215 when the lid 211 is properly clipped on. In the case in which the plug 219 is pulled out of the closable passage 214, air flows into the spray gun cup inside 215 via the opening thereby released through the lid 211.

The plug 219 is fixed in this embodiment in a recess 240 on the lid 211.

The collar 218 of the closable passage 214 forms a depression 241 of the large lid 211, at which the collar 218 tapers conically. As a result, the closable passage 214 has a large diameter in the region of the depression 241 and in the region on the collar underside 242 the collar 218 a much smaller diameter. According to the shape of the closable passage 114, the plug 219 is also formed.

This has the one advantage that the plug 219 can be plugged into the large diameter of the sink 241 simply and thus particularly quickly, whereby the plug 219 experiences a kind of pre-centering. Subsequently, the plug 219 slides smoothly into the smaller diameter of the collar 218 due to the tapered collar 218 and closes with a small diameter the closable passage 214 mainly in the area of the collar bottom 242. Because of this, the plug 219 can only with its smaller end face 243 come into contact with the contents 239 of the single-walled spray gun cup 202. Accordingly, the risk is substantially reduced that when pulling out the plug 219 from the closable passage 214 a larger amount of the contents 239 passes from the spray gun cup inside 215 and dirty areas or components (not shown here) outside the single-walled spray gun cup 202.

On the contrary, due to the small area of the end face 243 of the plug 219, only a very small spray gun cup content 239 will pass from the interior 215 of the single-walled spray gun cup 202 when opening the closable passage 214.

In addition, since the single-walled spray gun cup 202 is designed as a one-way spray gun cup, the single-walled spray gun cup 202 has a thickening spray gun cup wall 245 along its longitudinal axis 244 from its upper edge 213 toward its circumferential land 235.

The fact that the cup wall 245 is thicker in the lower region of the Spritzpisbolenbechers 202 than in the upper region, receives the single-walled spray gun cup 202 as a whole a stable shape. In contrast, due to the fact that the single-walled spray gun cup in the region of a large opening 210 has a less strong spray gun cup wall 245, not a considerable amount of material is saved in producing the single-walled spray gun cup 202.

The single-walled spray gun cup 402 illustrated in FIG. 4 essentially corresponds to the single-walled spray gun cup 202 from FIG. 2. The single-walled spray gun cup 402 likewise has a variable wall thickness 445 and has a resealable lid 411 at its upper opening 410. The lid 411 is snap-fastened to the edge 413 of the single-walled spray gun cup 402. The cover 411 also has a resealable passage 414, which is formed on the one hand by a depression 441 and, moreover, by a collar 418 adjoining the depression 441. The reclosable passage 414 is closed by a plug 419. In the interior 415 of the single-walled spray gun cup 402, a screen 438 is arranged, which is arranged on a small opening 407 of the single-walled spray gun 402. At the side of the small opening 407 is a latching terminal 430 and a circumferential ridge 435, which has a circumferential spring 437.

At the locking terminal 430, an adapter 403 is arranged in this embodiment. Here, the adapter 403 is fixed by a first guide ring 432 and a second guide ring 433 and a sealing ring 434 to the single-walled spray gun cup 402 latching. In addition, the spring 437 of the circumferential web 435 snaps into a corresponding adapter groove 455, so that the adapter 403 additionally stops at the single-walled spray gun cup 402

The adapter 403 is screwed by means of an adapter threading thread 456 to the receptacle 104 of a spray gun 101 (see Figure 1).

The small cover 508 screwed in FIG. 5 is pushed over the adapter thread 456 of the adapter 403 (see FIG. 4) if necessary, so that the small opening 407 of the single-walled spray gun cup 402 is closed by it. Due to the small lid 508 and the large lid 411, the single-walled spray gun cup 402 is completely closed so that the cup contents 439 are prevented from exiting the inside of the cup 415.

The single-walled spray gun cup 602 of Figure 6 also has a large lid 611 which is clamped to the single-walled spray gun cup 202. The large lid 611 has a closable passage 614 in which a plug 619 is disposed closing the closable passage 614.

In the region of its small opening 107, the single-walled spray gun cup 602 has a latchable connection 630, via which the single-walled spray gun cup 602 can be arranged on an adapter 403 (see FIG. 4) or on a receptacle 104 of a spray gun 101 (see FIG. 1).

In this exemplary embodiment, the latching connection 630 comprises a plurality of latching means 660 (numbered here only by way of example), which are provided in the form of a circumferential spring 237 (see FIG. 2) on the latching connection 630. These latching means 660 are sufficient to reliably secure the single-walled spray pod cup 602 to a designated location.

In the figures 7 to 10 is shown in each case on an embodiment in which manner the latching terminal 630 can be secured by two additional webs.

Accordingly, each of FIGS. 7 to 10 shows the detent port 630 of FIG. 6 with an additional web 761 in addition to the detent 660 and with an additional second web 762 (see FIG. 7), with an additional first web 861 and with an additional second web 862 (see FIG 8), a first web 961 and a second web 962 (see Figure 9), and ultimately a first web 1061 and a second web 1062 (see Figure 10).

In this case, the two webs 761 and 762 each have a spherical end 763 (numbered here only as an example), the two webs 861 and 862 have a triangular end 864 (numbered here only as an example), the two webs 961 and 962 each have a rectangular end 965 (here only exemplified) and the two webs 1061 and 1062 each have a square end 1066 (numbered here only by way of example).

The additional webs 761, 762, 861 and 862, 961 and 962 as well as 1061 and 1062 described in FIGS. 7 to 10 are not arranged peripherally around the connection 630 and correspond, for example, respectively to a web receiver 1270 and 1271 of an adapter 1203 (see FIG. 12) ).

FIG. 11 shows an adapter 1103, in the cup-shaped region 1167 of which, for example, the spray gun cup 602 (see FIG. 1) can be arranged. In this case, the latching means 660 (see FIG. 6) of the single-walled spray gun cup 602 respectively correspond to an adapter groove 1168, so that the single-walled spray gun cup 602 is fixedly but detachably attached to the adapter 1103. The single-walled spray gun cup 602 gains additional secure hold through the large bowl-shaped area 1167 of the adapter 1103. With the adapter end 1169, the adapter 1103 is attached, for example, to a spray gun 101 (see FIG. 1).

FIG. 12 also shows an adapter 1203, which also has a bowl-shaped region 1267. In addition, the adapter has 1203 Adaptemuten 1268 (here only exemplified), in which corresponding locking means 660 (see Figure 6) can engage.

In addition, the adapter 1203 has in its shell-shaped region 1267 two web receptacles 1270 and 1271, in each of which the first web 761 and the second web 762 (see FIG. 7) can engage. As a result, a single-walled spray gun cup 602 (see FIG. 6) receives an additional hold on the adapter 1203.

The web receptacles 1270 and 1271 each have an insertion region 1272 and 1273, in which in particular the spherical terminations 763 of the two webs 761 and 762 are introduced.

If the two webs 761 and 762 are inserted into the web receptacles 1270 and 1271, the single-walled spray gun cup 602 and the adapter 1203 are rotated against each other such that the spherical terminations 763 are moved into a holding region 1274 and 1275 of the web receptacles 1270 and 1271. Because the retaining portions 1274 and 1275 are narrower than the diameter of the spherical seals 763 of the two webs 761 and 762, the single-walled spray gun cup 602 can not be removed from the adapter 1203 without a backward rotary motion.

It is understood that all the above-explained locking terminals are merely exemplary embodiments and a latching connection can be realized via a plurality of further embodiments. Therefore, the foregoing embodiments are merely illustrative and not restrictive of the present inventive concept.

In addition, it is also possible. Spray gun cup without latching connection to a cup-shaped or plate-shaped adapter 1103 (see Figure 11) to order. Thus, it is possible to arrange a spray gun cup 102 (see Figure 1) via a threaded connection to cup-shaped or plate-shaped adapters 1103. For example, the plate-shaped adapter can also be arranged by means of a coupling ring to the spray gun bach.

In this regard, it should be noted that such adapters 1103 are not limited to additional cup-shaped or plate-shaped holding regions 1167, 1267. In further embodiments, such adapters 1103 can also have differently designed additional projecting spray gun cup holding regions, on which a single-walled spray gun cup 102 advantageously rests or is supported.

Moreover, it is also possible that such supporting or holding and cantilevered holding regions 1167, 1267 are not only provided by an adapter 1103, but such additional spray gun cup holding regions 1167, 1267 are arranged directly on a spray gun 101 (see FIG. 1). In such a case, the spray gun 101 directly in a region of the conventional receptacle 104, to which the single-walled spray pod cup 102 is arranged, such a cup-shaped or dish-shaped region 1167 or 1267 on. Here, the single-walled spray gun cup 102 is arranged directly on the spray gun 101, with the single-walled spray gun cup 102 additionally being directly supported or leaning against the cup-shaped or dish-shaped region 1167. It is understood that such a holding region 1167 or 1267 on the spray gun 101 can also be realized in another shape. For example, a similarly acting holding area 1167 or 1267 has only holding arms, by means of which the single-walled Spottzot cup 102 finds additional hold on the spray gun 101.

Due to the fact that a spray gun cup 102 on a spray gun 101, which has the additional holding portions 1167, 1267 described above, receives additional holding security, the features with respect to a spray gun 101 with such or similar shaped holding portions 1167, 1267 are also independent of the Other features of the present invention advantageous.

In this way, in addition to a first holding area for a spray gun cup 102, a spray gun 101 has a further additional holding area 1167, 1267 for the spray gun cup 102, which considerably simplifies arranging a spray gun cup 102 on a spray gun 101 and thereby also makes it safer.

In order to be able to easily arrange a spray gun cup, in particular a single-walled spray gun cup 102, by means of an adapter 103 (see FIG. 1) on a receptacle 104 of a spray gun 101, it is advantageous if a connection 230 of the single-walled spray gun cup 102 has a locking device. The Verriegchmgseinrichtung ensures that the single-walled spray gun cup 102 is preferably arranged undetachably on an adapter 103. This has the advantage that the spray gun cup 102 is so intimately connected to the adapter 103, that the two interconnected components form a compact unit and the adapter 103 can be easily attached to the spray gun 101 or released from it again, without affecting itself the single-walled spray gun cup 102 releases from the adapter 103.

This is particularly advantageous when it is necessary for the connection of these individual components "single-walled spray gun cup 102, adapter 103, spray gun 101" to perform a rotational movement between the individual components in order to connect the respective component with a corresponding component. If the connection 230 of the single-walled spray gun cup 102 has such a locking device, there is no risk of the component unit "single-walled spray gun cup 102 / adapter 103" also detaching when the adapter 103 is detached from the spray gun 102. Thus, by means of the Verriegehmgseinrichtung prevents the connection between the spray gun cup 102 and the adapter 103 unintentionally dissolves when you solve the adapter 103 of the spray gun 101. For example, the present locking device operates on the principle of a Kabelbinderverschlussc so that an insoluble placement of a first component to another component is structurally particularly easy to implement

A non-releasable locking device, which produces a permanent connection between the single-walled spray gun cup 102 and the adapter 103, is particularly advantageous if the components used are disposable components which are disposed of after use. In this way, the locking device can be structurally produced in a particularly simple manner and is therefore also cost-effective to implement.

If it is not disposable components with regard to the single-walled spray gun cup 102 and the adapter 103, but if these are to be used several times, it is advantageous if the Verriegelungseinrichnmg additionally has an unlocking means. In this case, there is the possibility that the operation of the unlocking means of the single-walled spray gun cup 102 despite the existing Locking device can be solved by the adapter 103. However, if the unlocking of the locking device is not actuated, the single-walled spray gun cup 102 can not be solved by the adapter 103, so that the component unit of single-walled Sputzpistoienbecher 102 / adapter 103 "when attaching to a spray gun 101 and in particular when releasing a spray gun 101 unchanged intimately Thus, the single-walled spray gun cup 102 can be arranged particularly easily on the spray gun 101 despite an adapter 103 interposed between it and the spray gun 101.

The adapter 1303 shown in FIG. 13 has a first receiving area 1380 for receiving a single-walled spray gun cup 102 (see, for example, FIG. 1) and, moreover, a second receiving area 1381 for receiving a spray gun 101 (see, for example, FIG. 1). Both receiving areas 1380 and 1381 are pivotally connected to each other by means of a rotation axis 383. This makes it possible that the first receiving area 1380 according to the double arrow 1384 about the axis of rotation 1383 and thus also about the second receiving area 1381 can be pivoted. It goes without saying that the second receiving area 1381 can accordingly also be pivoted about the axis of rotation 1383 and consequently also about the first receiving area 1380.

Advantageously, as a result, a single-walled spray gun cup 102 can be arranged much simpler on the first receiving area 1380 of the adapter 1303, since the first receiving area 1380 can be aligned almost independently of the position of the spray gun 101 with respect to the single-walled spray gun cup 102 to be fastened.

The first receiving area 1380 is fastened in this embodiment in the manner of a bayonet closure on the single-walled spray gun cup 102. Thus, a particularly rapid attachment and removal of the single-walled spray gun cup 102 from the first receiving area 1380 of the adapter 1303 is possible.

In addition, the second receiving area 1381 has a thread (not explicitly shown here) with which the adapter 1303 can be screwed to a commercially available spray gun 101.

In the region of an interface 1385 between the first receiving area 1380 and the second receiving area 1381, the adapter 1303 is machined such that a coating agent from the single-walled spray gun cup 102 but the hinged adapter 303 easily enters the spray gun 101.

FIG. 14 illustrates another articulated adapter 1403. The articulated adapter 1403 likewise has a first receiving region 1480 and a second receiving region 1481, which are connected to one another in an articulated manner by means of a suitable rotational axis 1483.

The articulated adapter 1403 comprises an additional paint conduit 1486, via which a coating agent passes from the first receiving region 1480 to the second receiving region 1481. In this embodiment, the additional paint shop line 1486 is outside of the articulated adapter 1403.

Due to the additional paint line 1486, the interface 1485 between the first receiving area 1480 and the second receiving area 1481 need not be laboriously processed with small tolerances, so that the articulated adapter 1403 is more cost-effective to produce compared to the articulated adapter 1303.

FIG. 15 shows a further articulated adapter 1503, which on the one hand has a narrower but higher first receiving area 1580 and, on the other hand, a narrower, but higher second receiving area 1581 than the two articulated adapters 1303 and 1403 explained above.

Both receiving areas 1580 and 1581 are also connected to one another in an articulated manner via an axis of rotation 1583, so that the first receiving area 1580 and the second receiving area 1581 are pivotable relative to one another, and thus the advantages explained above are achieved.

16 has a bottom 1690 in which a closable passage 1614 is incorporated. The closable passage 1614 in the context of the invention provides additional access to the interior 1615, ie to the Lackiermittetaumahmebereich the spray gun cup 1602. Limited is the bottom 1690 by a peripheral bottom collar 1690 A, which is formed so that a collar 1618 of the closable passage 1614 can be easily arranged on the outside 1690B of the bottom 1690. Thus, the single-walled spray gun cup 1602 can be easily parked with its encircling cup collar 1690A on a base 1688. On the outside 1690B of the bottom 1690, a plug 1619 is arranged, with which the closable passage 1614 can be closed. When the stopper 1619 is inserted, the closable passage 1614 is closed in such a way that the inside 1690C of the bottom 1690 forms a substantially planar surface. For this purpose, the plug 1619 is shaped so that it does not protrude beyond the bottom inner side 1690C when closing the passage 1614, nor does it lie behind the bottom inner side 1690C. The flat surface makes it possible, with a single-walled spray gun cup 1602 placed on the revolving floor collar 1690A, to introduce a stirrer for mixing a two-component enamel into the single-walled spray gun cup 1602, so that mixing of the two-component enamel can advantageously be carried out directly in the single-walled spray gun cup 1602.

The feature that the plug 1619 forms a planar surface when the passage 1614 is properly sealed to the bottom inside 1690C is also independent of the other features advantageous to the invention. As a result, a color change is greatly simplified, since a paint 1639 can be used much faster if it is mixed directly in the single-walled spray gun cup 1602.

At the opposite end of the single-walled spray gun cup 1602 from the bottom of the cup 1690, a spray gun cup lid 1691 is fastened by means of a coupling ring 1692.

On the spray gun cup lid 1691, a circumferential bar 1635 is injection-molded, by means of which the spray gun cup lid 1691 can be locked in a snap-lock manner on a spray gun 101 (see FIG. 1). In the immediate vicinity of the circumferential web 1635 is a latching connection 1630. In addition, the circumferential web 1635 has on its side facing the stainless port 1630 side 1636 a circumferential spring 1637, which serves to lock into a corresponding adapter groove 1655 of an adapter 1603. To facilitate such engagement of the rotating spring 1637, the circumferential ridge 1635 is made of an elastic material.

In order to produce an additional security between the single-walled spray gun 1691 and the adapter 1603 and to seal the two components against each other, the latching connection 1630 has both a sealing ring 1632 and a first guide ring 1633 and a second guide ring 1634. It is understood that in the present case the sealing ring 1632 can also assume a guiding function. Accordingly, the first and second guide rings 1633 and 1634 can also perform sealing functions.

In addition, a screen 1638 is arranged on the spray gun cup lid 1691, which filters a coating agent 1639 before it passes from the interior 1615 of the single-walled spray gun cup 1602 into a spray gun 101 (see FIG. 1).

In order to be able to carry out an infestation of the single-walled spray gun cup 1602 even with a spray gun cup lid 1691 screwed on, a wiper retainer opening 1693 adjacent to a main opening 1694 is provided on the spray gun cup lid 1691. The resealable refill opening 1693 is closed in this embodiment with a screw 1693A. It goes without saying that other means of closure may also be provided in order to close the reclosable refill opening 1693 in the sense of the invention.

Incidentally, such a refilling opening 1693 could also be provided in the region of the single-walled spray gun enclosure 1602.

The features with regard to the reclosable refill opening 1693 are also advantageous without the other features of the invention, since filling of an already used single-walled spray gun cup 1602 can be made faster by the refill opening 1693.

In another embodiment, it is also possible to attach the spray gun cup lid 1691 directly to the single-walled spray gun cup 1602 without a collar 1692. For this purpose, a stick, Smlp- or screw connection could be provided.

To also close the main opening 1694 of the spray gun cup lid 1691, the spray gun cup lid 1691 includes a cap 1695.

In the single-walled spray gun cup 1602 closed by the spray gun cup lid 1691 and the plug 1619, a paint agent 1639 is filled.

The arrangement 1700 shown in FIG. 17 essentially comprises a spray gun 1701, a single-walled spray gun cup 1702, a spray gun cup lid 1791 and an adapter 1703. The single-walled spray cup cup 1702 has at its cup bottom 1790 a closable passage 1714 which is closed by a plug 1719.

On the side 1796 ontgegengosetzten the spray gun cup bottom 1790, the single-walled spray gun cup 1702 has an external thread 1797 on. On the external thread 1797 of the spray gun cover 1791 is screwed so that the single-walled spray gun cup 1702 and the spray gun beaker 1791 form a solid but detachable unit.

On the inside of the spray gun cup lid 1791, a screen 1738 is disposed to filter the spray gun cup contents before exiting, for example, into the spray gun 1701.

The single-walled spray gun 1791 has an additional reclosable refill opening 1793 with a 1793A screw cap. The main opening 1794 of the spray gun cup lid 1791 may be closed with a closure 1795 if necessary. This is the case, for example, if a paint spray agent 1639 (see FIG. 16) is to be stored in the single-walled spray gun cup 1702 closed by means of the plug 1719 and the spray gun cup cover 1791.

In order to be able to attach the spray gun cup lid 1791 with its main opening 1794 to any spray gun 1701, the adapter 1703 is arranged between the spray gun cup lid 1791 and the spray gun 1701

The arrangement 1800 shown in FIG. 18 essentially comprises a spray gun 1801, a single-walled spray gun cup 1802 and an adapter 1803. To the single-walled spray gun cup 1802 includes a spray gun cup lid 1891, which is secured in this embodiment by means of a coupling ring 1892 on the single-walled spray gun cup 1802.

In order to secure the coupling ring 1892 to the single-walled spray gun cup 1802, the single-walled spray gun cup 1802 has an external thread 1897. A corresponding internal thread (not shown here) has the coupling ring 1892 on.

In the area of the spray gun cup bottom 1890, the single-walled spray gun cup 1802 has a closable passage 1814 which can be closed by means of a stopper 1819.

In addition to the main opening 1894, the spray gun cup lid 1891 has a resealable refill opening 1893 which is closed by means of a screw cap 1893A. In addition, the spray cap cup 1891 has a latching connection 1830 with latching means 1860. In order to arrange the spray gun cup cover 1891 particularly reliably on the adapter 1803, the spray gun cup lid 1891 additionally has a first web 1861 and a second web 1862. The additional webs 1861 and 1862 clamp the spray gun cup lid 1891 to the adapter 1803. In order to adjust the spray gun cup 1891 in particular before being screwed over the single-walled spray gun cup 1802, the spray gun cup lid 1891 on the side facing the single-walled spray gun cup 1802 an inner guide 1898 on. Thus, the spray gun cup lid 1891 can be arranged particularly quickly and safely on the single-walled spray gun cup 1802. In this embodiment, the inner guide 1898 is a circumferential ring.

A screen 1838 is also disposed on the spray gun cup lid 1891. This is introduced from the squeegee side into the main opening 1894 of the spray gun cup lid 1891.

In addition, in order to close the main opening 1894, the arrangement additionally includes a cap 1895th

The single-walled spray gun cup 1802 is made of a clear material and has a scale 1899. By means of the scale 1899 in particular the mixing of two-component paints in the single-walled spray gun biter 1802 is made much easier, since the individual components are very easy to dose on the basis of the scaling.

The single-walled spray gun cup 1902 shown in FIG. 19 additionally has a resealable refill opening 1993 in the region of its spray gun cup bottom 1990 in addition to a closable passage 1914. The reclosable refill port 1993 can be closed by means of a stopper 1993B.

On the side opposite the spray gun body bottom 1990, the single-walled spray gun cup 1902 has an external thread 1997, on which a spray-gun cup cover 1891 (see Figure 18) can be screwed.

The reclosable refill opening 1993 in the area of the cup bottom 1990 next to the closable passage 1914 makes it possible to fill the single-walled spray gun cup 1902. Here, the closable passage 1914 advantageously serves to ensure that air escapes from the spray gun cup interior 1915 when refilling a coating agent 1639 (see FIG. 16) via the closable passage 1914

In this embodiment, as regards the spray gun cup 1891, a resealable refill port 1893 (see FIG. 18) may be dispensed with, since a corresponding refill port 1993 is provided on the cup bottom 1990 of the single-walled spray gun cup 1902

In contrast to the exemplary embodiment with a reclosable refill opening 1993 arranged on the spray gun cup bottom 1990 next to the closable passage 1914, a screw cap 2093A of a resealable refill opening 2093 can also have a closable passage 2014 (see FIG. 20). In this case, the reclosable refill opening 2093 and the closable passage 2014 are united together in one component. The closable passage 2014 is closed in this embodiment, if necessary by means of a plug 2019.

Due to the resealable passage 2014 on the screw cap 2093A of the resealable refill opening 2093, a washable passage 2014 directly in the spray gun cup bottom 2090 can be dispensed with. Thus, the previously separate two openings - the closable passage 1914 and the reclosable refill opening 1893 - are merged into only one opening at the spray gun cup bottom 2090.

As in the case of the single-walled spray gun cups described above, the single-walled spray gun cup 2002 has an external thread 2097 on its side 2096 opposite the spray-dispenser cupboard bottom 2090, via which a spray gun cup cover 1981 (see FIG. 18) can be arranged on the single-walled spray gun cup 2002. Advantageously, a resealable refill opening 1893 (see FIG. 18) can be dispensed with, since a corresponding refill opening 2093 is provided on the spout pistol floor 2090 of the single-walled spray gun cup 2002.

The single-walled spray gun cup 2102 shown in FIG. 21 has a spray gun cup lid 2191. The spray gun cup 2191 has a main opening 2194, above which the spray gun cup lid 2191 either directly with a receptacle 104 of a spray gun 101 (see Figure 1) or with an adapter 103 or with a plate-shaped adapter 1203 (see Figure 12) communicates. In the present embodiment, the spray gun cup lidding 21.91 is formed substantially conical, so that the spray gun cup cover 2191 is particularly well supported on the holding portion 1267 of the plate-shaped adapter 1203. So that the spray gun cup lid 2191 can be arranged latching on the plate-shaped adapter 1203, the spray gun cup lid 2191 has on its cone-shaped outer side a first latching web 2161 and a second latching web 2162, with corresponding latching web receptacles 1270 and 1271 (see, for example, Figure 12) of the plate-shaped adapter 1203 together. In order to connect the spray gun cup lid 2191 to the spray gun cup 2102, the spray gun cup 2102 has an external thread 2197 with which the spray gun cup 2102 is screwed to the spray gun cup lid 2191. It is understood that the spray gun cup lid 2191 for this purpose has a corresponding internal thread (not shown here). The external thread 2197 and the internal thread, not shown here, of the spray gun cup lid 2191 are such that the spray gun cup lid 2191 can be fixed by means of a quarter turn about its longitudinal axis 2198 to the spray gun cup 2102. For this purpose, the spray gun cup lid 2191 is first placed on the spray gun cup 2102 and then rotated about its longitudinal axis 2198 in a clockwise direction. The spray gun cup 2102 has a locking device 3000 in the region of the external thread 2197. By means of this locking device 3000 it is ensured that the spray gun cup lid 2191 can be arranged on the spray gun cup 2102 so that they do not unintentionally separate from each other when the spray gun cup lid 2191 with its first latching web 2161 and with its second latching web 2162 by means of a rotary movement in corresponding latching web receptacles 1270 and 1271 of the plate-shaped adapter 1203 is engaged or disengaged. The pre-locking device 3000 advantageously prevents the connection between the external thread 2197 of the spray gun cup 2102 and the corresponding internal thread of the spray gun cup lid 2191 from unintentionally being released during such a latching movement. Thus, the danger that the spray gun cup 2102 falls off the spray gun cup lid 2191 in the worst case is reduced. In this embodiment, the locking device 3000 is designed such that it can be unlocked again. For this purpose, a corresponding "pushing" from the outside in the region of the Verriogehrngseinrichtung 3000 is sufficient in the rule. Unlocking is particularly advantageous if the present spray gun cup 2102 and the associated spray gun cup lid 2191 are designed to be reusable.

On the other hand, a locking device 3010 which can not be unlocked again has the spray gun cup 2202 (see FIG. 22). The spray gun cup lid 2291 has substantially the same structure as the gun cup lid 2191 of Figure 21. The spray gun cup lid 2291 is conical and has a main opening 2294, over which the spray gun cup cover 2291 is preferably arranged on a plate-shaped adapter 1203 (see Figure 18). In order to obtain a particularly secure hold on this plate-shaped adapter 1203, the spray gun cup cover 2291 has a first latching web 2261 and a second latching web 2262 which communicate with corresponding latching web receptacles 1270 and 1271 (see FIG. 12) of the dish-shaped adapter 1203.

The latching device 3010 has a first circumferential elevation 3020 and a second circumferential elevation 3030. The interior of the spraygun cup 2291 that communicates with the elevational assembly 3010 also includes such elevations and / or grooves communicating with the circumferential elevations 3020 and 3030. In a simple embodiment, the spray gun cup cover 2291 on the spray gun cup 2202 side facing a simple undercut, which engages behind the respective elevation 3020 or 3030 of Vernegelungseignchtung 3010 when the spray gun cup 2291 is printed on the spray gun cup 2202. The embodiment of the locking device 3010 shown here can no longer be unlocked, since the locking device 3010 shown here acts substantially similar to a generally known closure of a cable tie. Thus, the spray gun cup lid 2291 is no longer detachable from the spray gun cup 2202. Therefore, the latch assembly 3010 shown herein is primarily for disposable components that are disposed of after use and are not cleaned again for further use. So that the spray gun cup 2202 does not twist relative to the spray gun cup 2191 when the spray gun bezel 2291 is arranged on a spray gun 101 or preferably on a plate-shaped adapter 1203, the locking device 3010 has a fixing 3040 arranged essentially transversely to the peripheral elevations 3020 and 3030 Embodiment, the fixation 3040 is a web which interacts with a corresponding groove (not explicitly shown here) on the inside of the spray gun cup cover 2291. When placing the spray gun cup cover 2291 on the spray gun cup 2202 of the spray gun cup cover 2291 is brought in the direction of arrow 3050 to the spray gun cup 2202 and pressed so firmly against this until both components lock together.

Both the spray gun cup 2102 and the spray gun cup 2202 can be particularly advantageously filled when they are parked on a footprint 3100. In such a position, the respective spray gun cup lid 2191 or 2291 can be securely arranged on the spray gun cup 2102 or 2202 provided therefor.
