Description
Technical field
The present invention relates to the pressurized aerosol container, these containers comprise a specific valve, and the type of this valve is through operating to distribute the humidity-reactive complex in aerosol form, as isocyanurate foam.Specifically, the distribution that the present invention relates to have aerosol can of a valve and liquid for this tank is comprised becomes and is easy to a kind of combination of a distribution adapter, described combination allows this adapter to be connected to easily on this valve, thereby has guaranteed being tightly connected and can not overflowing any liquid when being fixed on this valve by this distributing box.
Background of invention
Typically, be fixed to pressurized tank for the aerosol valve of distributing the humidity-reactive complex (as the isocyanurate foam precursor) in aerosol form by a cup shell, this cup shell seals this open top by means of the peripheral annular passage around periphery tank beading, and this periphery tank beading limits the girth of this tank top opening.This cup shell comprises a medium pore, tubulose elastomeric grommet through this medium pore simultaneously above this cup shell with below extend (" below " that is expressed in cup shell and " top " refer at this that respectively inside towards tank is with outside).This grommet is a hollow, cylindrical tube haply, the medium pore of this hollow, cylindrical tube is all opened at two ends, and the end of this hollow, cylindrical tube below it is positioned at this cup shell comprises extend radially outwardly one roughly ringwise flange, and the upper surface of this hollow, cylindrical tube contacts and is applicable to (interior) surface under this cup shell and sealed against the latter.
Rigid stem snugly be combined in the medium pore of this grommet and below described grommet with above extend, and be maintained at appropriate location by suitable device (being generally the annular lip that is clipped in top and the centre, bottom of grommet).This valve rod is formed by a hollow tubular, this hollow tubular is sealed by an annular substrates first end, this annular substrates forms a flange, the diameter of this flange is greater than the diameter of the endoporus of grommet, and the upper surface of this base flange is applicable to be sealed against the lower surface of this grommet flange.The sidewall of the tubular portion of this bar generally includes a plurality of openings, and these openings make the endoporus of this bar with the interface phase fluid communication between bar substrate and grommet flange.
By tilting and/or pressing the part that valve rod extends out from grommet downwards, the seal interface between at the bottom of grommet flange and valve base is destroyed, thereby makes the complex phase fluid UNICOM comprised in the endoporus of valve rod and tank.Because tank pressurizes, the content of tank is distributed by valve.When valve is closed, valve must be guaranteed the content of the moisture contact tank that do not come from the outside, especially in the situation that complex moisture is responded.Being applicable to minute example of the valve design of the pressurization complex (as a kind of isocyanurate foam) that the pairing moisture responds can find in WO2006/032061, US6.425.503, US4.765.516, EP0.102.797, WO2009/042206, WO96/17795.
Such tank and valve system for example, are widely used in the isocyanurate foam complex by ().They are usually sold (typically 1 liter tank or still less) with form quite in a small amount and are disposable.For storing reason, and for the packing of the pressurized tank that makes this class is compact as much as possible, valve rod normally straight and quite short on length.This causes this class tank is quite unpractical for use, because activate on short valve rod, is difficult, and the accuracy of being distributed in complicated position is quite not enough.Given this reason, these tanks often are equipped with an independent distribution adapter, this distribution adapter comprises that (on the one hand) actuating device promotes the actuating of valve, and (on the other hand) one longer, orientable distribution duct sometimes, thereby allow liquid is carried out the distribution of more accurate and compartmentalization.Can obtain this dissimilar class and distribute adapter; Especially that together with tank, sell and be particularly useful for DIY user's disposable distribution adapter, this disposable distribution adapter should come with the reusable distribution rifle difference of usually being used by professional, and these reusable distribution rifles are equipped with their pressure feeding mechanism sometimes.<0}
Cheap disposable distribution adapter for the DIY application normally is fixed directly to valve rod.Often use snap-fit system, bayonet formula system and similar system, but the shortcoming that these connected systems have is: they need to apply pressure to fixed allocation adapter on valve rod, and this often causes the undesirable of content of some pressurized tank when fixed adapter to be overflowed.This problem can solve by the distribution adapter that the valve rod with a male thread portion the female thread portion that fixedly has a coupling on this valve are provided, for example, disclosed in Fig. 5 of () WO9617795.
On the other hand, in order to guarantee to distribute the larger steadiness of rifle, often will distribute rifle to be screwed to this tank originally on, on a plug-in unit an or threaded portion directly (not on the valve rod) on cup shell and make it in place with it, and make to distribute the distribution duct of rifle connect end and valve rod phase fluid UNICOM by one.Sealing arrangement is provided at valve (for example, grommet) or be provided at and form on the sleeve that rifle connects end (as an O ring or a packing ring) originally with it.An embodiment of such geometric configuration is illustrated in Fig. 4 of WO9617795, and wherein sealing arrangement is to be formed by the valve grommet that comprises a plurality of rubber flange.
This means that the valve rod with male thread portion that is applicable to fixing disposable distribution adapter can not be used to fixedly remain directly to be screwed to a distribution rifle on tank, this is because at a connection end of this distributions rifle and comprise between the valve rod of male thread portion and can not form closely and seal.This seemingly inappreciable problem for valve maker, be but a subject matter, they must move a plurality of independent manufacturing lines, storage and dispensing appliance according to the type of following application:, remain the tank used together with disposable distribution adapter, wherein valve rod comprises a male thread portion; With remain and those tanks that use together with distribution rifle for than professional application, these tanks need level and smooth valve rod to guarantee air-tightness.
The application proposes the solution for this problem, thereby allow same valve rod can be applicable to best the distribution tank of two types:, the tank with disposable distribution adapter used and by using the professional's tank used that distributes rifle by DIY user.This advantage and other advantages will be explained in ensuing part.

Detailed description of the invention
The present invention relates to a kind of for the valve at pressurizing vessel, preferably mainly by the inclined valve that tilts to activate or the valve rod mainly used by the rifle valve (gun valve) of pressing to activate downwards.Preferably this valve is used to distribute the humidity-reactive liquid composition, as the isocyanurate foam complex of one or both compositions.As in Fig. 1 a plurality of embodiment was showed, the type of valve of the present invention is to comprise a valve rod (1), a grommet (2) and a valve cup shell (3).
Valve rod (1)
A valve rod (1) comprises a hollow tubular part (1A) that limits a medium pore (1C), first end that described valve rod has that environment towards periphery opens and by second opposite ends of (1B) sealing at the bottom of ringwise terminal groups roughly.The tubular portion of valve rod (1) preferably includes a flange (1D), and this flange is for being held in place grommet (2) (being defined hereinafter) and being used to form the tight seal with a disposable distribution adapter (5).The upside of this flange (tank) dorsad preferably has the geometric configuration of frustoconical in order to strengthen and the sealing that distributes adapter.
The medium pore of this valve rod (1C) is included in adjacent end substrate (1B) on tubular portion (1A), away from first open-ended at least one side opening (1E), thereby formed fluid communication between two ends of this valve rod.
According to the present invention, the medium pore of this valve rod (1C) comprises the anchor fitting of internal thread part form-separating, with for a disposable distribution adapter directly is fixed to this valve, and need not press this valve downwards in order to its bayonet fitting is put in place.A rotary screwing thread (1F) is to be limited by a continuous helical groove on the inside face of the medium pore (1C) of this valve rod.Fig. 5 has showed the example according to female thread portion of the present invention.A kind of interior rotary screwing thread is characterised in that and ridge (1cr) that by flank (1fl) engaged outstanding from root (1rt).These flanks are not parallel each other, and two flanks (1fl) locate to engage shape at an angle alpha at same (1rt), this angle be preferably more than 20 °, more preferably be greater than 30 °, most preferably be greater than 35 °.Best, angle [alpha] should be included between 45 ° to 60 °, typically is approximately 50 ° ± 5 °.As known in the art, just permit being screwed to such negative thread (1F) at the outside thread by coupling in a plurality of taper paddy that therefore form between locate to engage at same (1rt) with not parallel flank (1fl) two ridges (1cr) and reduced to rub when upper, and guarantee so the air-tightness of the joint that forms.For example, US20060048843 has disclosed a kind of valve rod for pressure gas containers, and this valve rod comprises a static mixer, and the form of this static mixer is a spiral groove on the inside face of the medium pore of this valve rod.The flank of this groove is all parallel to each other.Therefore such spiral groove is not suitable for the distribution adapter of receiving and fixedly be equipped with the coupling screw thread.Due to the height friction, it will be difficult that this adapter is screwed on such screw thread, and, because the interior pressure of tank will make male thread press the flank towards container, the joint formed thus will not be bubble-tight, thereby open a continuous fluid passage along the flank of container dorsad.
In a preferred embodiment, the width that these ridges (1F) and root (1rt) have be included in 0.1 and 3mm between, preferably 0.3 and 1.5mm between, most preferably 0.5 and 1.0mm between.Pitch (two adjacent ridge between distance) be preferably included in 0.5 and 8.0mm between, more preferably 2.0 and 7.0mm between, about 5mm ± 1.0mm most preferably.The magnitude that the degree of depth of this groove (that is, survey along the radius of medium pore from the ridge to the root distance) has is 0.2 to 0.5mm, be preferably included in 0.2 and 0.4mm between.All sizes recited above are all to record being parallel on a cross section of the axis of endoporus as show in Figure 5.
Grommet (2)
Valve of the present invention comprises a grommet (2) of being made by elastomeric material (as, elastic body).This grommet is used for guaranteeing the air-tightness of valve, thereby (on the one hand) valve rod (1) forms sealing with (on the other hand) cup shell opening (being defined hereinafter).This grommet has a hollow tubular part (2A) that limits a central through hole, this central authorities' through hole is snugly and closely around the part between (1B) at the bottom of bar flange (1D) and bar terminal groups that is included in of the tubular portion of valve rod (1A), and comprise a ring flange part (2B) at this grommet of the first end of the inside towards container, the diameter of this ring flange part is greater than the diameter of valve rod substrate (1B), and the lower surface of flange portion (2B) is sealed against the top surface of valve rod flange (1B).
Grommet (2) can be made by any elastic body with required machinery and chemoresistance (as poly-chloroprene rubber or thermoplastic elastomer (TPE)).
The bottom section of the medium pore of grommet (2) can comprise next empty this at least one opening (1E) of opening valve rod (1) of depression.
Valve cup shell (3)
Valve of the present invention comprises the cup shell (3) for the deadend container.This cup shell by one thin, be generally annular plate and make, this plate comprises first inside face (3in) and second outside face (3out).This cup shell is equipped with a pass through openings that roughly is positioned at this cup shell center.These grommets are all the air-tightness of giving prominence to and guaranteed system on the both sides of described pass through openings.The opening of this cup shell preferably includes a circular edge in order to reduce fully the wearing and tearing of grommet (2) against described edge when using this valve.
As show in Figure 4, the neighboring of this cup shell (3B) is applicable to be sealingly secured on the upper opening of a container.Cup shell (3) can be by may be for anti-oxidant and aesthetic reasons and coated corrosion-resistant steel, aluminium, dry steel or the other materials steel plate of tin (as be coated with) are made.
This container preferably includes a flange (7G), and this flange is applicable to grasp the grip device (5G) that distributes adapter (5).Flange (7G) can directly be provided on this cup shell, and (for example) is connected to the position of this tank opening at it, or this flange can be a part that is fixed to the plug-in unit (7) on this cup shell, as show in Figure 4.Preferably, plug-in unit (7) also comprises and is suitable for a distribution rifle directly is fixed on this tank but not a male thread portion on this valve.
For the height that reduces this container and the ratio H/V of volume, this cup shell (3) preferably comprises the section (3A) of a general planar between this central authorities' through hole and neighboring (3B), in order to do not invade the volume depths of this container.
The purposes of inclined valve or rifle valve
When static, this valve for example, was bubble-tight being installed in a pressure container (aerosol can) when upper.Between grommet and cup shell and all interfaces between grommet and valve rod are all sealed, make like this between the inside of tank and surrounding environment and do not have fluid communication.The interior pressure of container has guaranteed that the substrate (1B) of this valve rod presses the lower surface of the flange (2B) against this grommet, and this lower surface seals and contacts mutually with the inside face (3in) of this cup shell again.As showed in Fig. 1 (b), when tilting and/or pressing valve rod (1) downwards, grommet (2) is bent and compresses, and the sealing between the lower surface of the flange (2B) of the substrate of this valve rod (1B) and this grommet is destroyed, thereby allow the liquid comprised in container flow out by bar opening (1E) and pass through hole (1C) at valve rod exit arrival surrounding environment (seeing black arrow).
As show in Figure 1, the short and straight valve rod for this class, it is unpractical tilting and/or pressing valve rod downwards.For this reason, often use a distribution adapter, this distribution adapter comprises that actuating device promotes the actuating (that is, by tilt and/or press) of this valve and a distribution duct to improve and distributes accuracy and permission to be distributed in more complicated position downwards.Can distinguish this class of two kinds of main Types and distribute adapter: the disposable distribution adapter of (a) paying together with each tank, and (b) can reuse and be more suitable for professional user's distribution rifle.The application's valve can indistinguishably use with pressurized tank together with this distribution adapter of two types.
Disposable distribution adapter
Distribution adapter according to the present invention comprises:
(a) a hollow distribution pipe (5C), this hollow distribution pipe has first dispense tip (5 is outer) and is connected end (in 5) with one second,
(b) actuating device (5A), this actuating device laterally is fixed on this distribution pipe and is allowed to activate this valve when in appropriate location.
Connect end (in 5) according to second of the distribution pipe (5C) of distribution adapter of the present invention and comprise that an outside thread (5F), this outside thread have the female thread portion (1F) of the valve rod be connected to be complementary with it.It is this that to be configured in a lot of aspects be favourable.As the negative thread of valve rod (1F) as discussed above, outside thread (5F) is to be limited by the continuous spiral groove on the inside face of the medium pore (1C) of this valve rod.The size of ridge, root and the pitch of outside thread (5F) should be mated the size of corresponding root, ridge and pitch of the negative thread (1F) of this valve rod, as discussed above.
The first, for the amateur user who not necessarily gets used to operating this class pressurized tank, disposable dispenser (5) is connected on this valve and does not activate unintentionally this valve during this process is to be relatively easy to.This obviously is better than snap-fit or bayonet formula system.The present invention is also because following reason is better than by the valve rod that comprises a male thread portion and comprises the system that screws that the distribution duct end (in 5) of a negative thread forms.
The connection end of the distribution adapter of the second, one correspondence must comprise a sleeve, and this sleeve comprises that a female thread portion is in order to assemble the male thread portion of this valve rod.This sleeve may limit the inclination of this valve and/or the degree of freedom of pressing, if particularly this cup shell is dark or used a plug-in unit (7).
The 3rd, in order between this distribution adapter and this valve rod, there to be gratifying a connection, this threaded portion must have a minimum length, this is in the situation that the outside of this threaded portion in this valve rod may adversely increase the length of this valve rod, and this is not problem at this threaded portion during in inside, because this through hole is longer than the valve stem part of the grommet that extends beyond external container.
The 4th, identical valve rod can be indistinguishably with a disposable adapter with together with a distribution rifle, use, the former needs a threaded portion to assign to this disposable adapter is fixed on this valve, and the latter needs a smooth valve rod outer wall with for contacting between rifle and valve, forming a sealing.
Distribute the actuating device (5A) of adapter (5) preferably to be a kind of shape of handle, this handle is from this distribution pipe horizontal expansion, and is adapted to thumb and palm by finger grip and holds this tank.Press this actuating device downwards by clenching fist, what strength the larger leverage provided due to actuating device (5A) does not take just can make valve tilt.In order to reach this effect, this actuating device can be equipped with ergonomics handle to guarantee good grasping and to prevent that finger (especially forefinger and middle finger) from sliding.
In a preferred embodiment, distribution adapter of the present invention further comprises a grip device (5B, 5G), this grip device laterally is fixed on this distribution pipe contrary with actuating device (5A) substantially, one second of described grip device grasps the flange (7G) that end (5G) is applicable to grasp a pressurizing vessel, and the second connection end (in 5) of this distribution pipe is screwed on the distributing valve of described container (6).The grasping end (5G) of grip device (5B) can be comprised of a hook formation, and this hook formation is applicable to be hooked on the depression of below of a flange (7G) that is positioned at this jar structure.For example, this jar structure can comprise a ring plugin (7) as show in Figure 4, this ring plugin is fixed on tank cup shell (3) above and comprises that a flange (7G), this flange preferably are equipped with a depression in order to allow by the next good grasping of grasping end (5G) of the grip device (5B) of this distribution adapter.Plug-in unit (7) can also comprise that a male thread portion (7F) is with the fixing as the distribution rifle by the professional was used for permission.Grasping level place in the flange (7G) that end (5G) is engaged to this jar structure during in grip locations has formed one and has been fixedly hinged a little when these grip devices, and the actuating of actuating device will cause the cantilever bending of this adapter, this cantilever bending is to the flexural force and the compressive force that apply a kind of combination on this valve.A compression component being applied to the advantage had on this valve when activating an inclined valve is to have alleviated when making valve rod (1) tilt to be applied to the pressure on grommet flange (2B) by valve stem end (1B).
In a favourable embodiment, distribute the orientation of the distribution duct (5C) of adapter (5) to be changed, as for example, by allowing this pipeline carry out certain bending (, adopt as for one section pleat pipe of the suction pipe of soda water) or realize by allowing this distribution duct to carry out certain rotation with respect to this container.
At another in favourable embodiment, this adapter can be included in the springing of the adjacent place of outside thread (5F), and this springing is applicable in this bar to snap fit onto corresponding to a position of the complete and bubble-tight joint of adapter the indenture that is arranged in a correspondence on this valve rod outer wall.This springing can be a projection, and this projection extends out and joins with the screw thread side from one of a plurality of side arms (50) on the direction of this screw thread.The flexibility of side arm (50) gives this system with elasticity.This Elastic buckle formula system needs not to be firmly, because it is not to be used as anchor fitting, and just as an aud. snl., notifies this adapter of user to twist tightlyer in this bar.
In same packing the combination as discussed above a valve (this valve has a valve rod (1), this valve rod is equipped with a female thread portion (1F)) with a distribution adapter as discussed above, (this distribution adapter has one and is connected end, this connection end is equipped with the female thread portion (5F) of a coupling) favourable part be that this same packing can sell the customer of DIY once in a while, they can use this pressurized tank with the disposable distribution adapter of supplying together with this pressurized tank together, also can sell the professional, they prefer to complete their work with more complicated distribution rifle.Such packing or external member are particularly useful for minute the liquid that the pairing moisture responds, as a kind of polyurethane precursor.
The tubular portion (1A) of valve rod (1) preferably includes the flange (1D) for grommet (2) is held in place.In a preferred embodiment, the top surface of described flange (1D)--, and towards the surface of this distribution outlet side--be frustoconical.This geometric configuration has strengthened this valve rod and the air-tightness be connected of distributing between adapter (5), condition is the frustoconical depression that this coupling end (in 5) of this distribution adapter is equipped with a coupling, when being screwed on this valve rod by this adapter, can make this frustoconical depression form sealing with the top surface of valve rod flange (1D) and contact.
This external member can be easily for distributing a kind of liquid simply in the following manner from this container:
