The liquid is distributed through a preferably hollow valve element, which also forms a nozzle.

Description

  • The invention relates to a dispensing device as set forth in one of the independent claims.
  • In the present invention, the term “dispensing device” is to be particularly understood as a dosing pump or hand-operated pump for the dispensing of a preferably cosmetic liquid. However, it can also be any other dispensing device such as a container, dispensing or spray head, dispenser or the like, particularly for a cosmetic liquid.
  • The term “cosmetic liquid” is to be understood, in a narrower sense, as cosmetics, hair spray, hair lacquer, a deodorant, a foam, particularly shaving foam, a gel, a color spray, a sun protection or skin care agent or the like. Preferably, however, in a broader sense, other body care products, cleaning products or the like, and even suspensions and fluids, particularly those with gas phases, are included as well. Moreover, other liquids, for example air improvers and particularly technical liquids and fluids as well such as rust removers and the like, can as be used. Nonetheless, for the sake of simplicity and due to the emphasized use, there is often only mention of cosmetic liquid in the following.
  • WO 2004/073871 A2 discloses a dispensing device with several pump chambers. Each pump chamber is delimited by an elastically deformable pump part. These pump parts can be simultaneously deformed by a common actuating element in order to dispense different liquids via a likewise common outlet valve simultaneously.
  • It is the object of the present invention to provide a dispensing device which can be used universally, has a simple construction, a robust design, is simple to operate and/or, particularly, can be used overhead.
  • The abovementioned object is achieved by a dispensing device as set forth in one of the independent claims. Advantageous modifications are the object of the subclaims.
  • One aspect of the present invention consists in that the dispensing device dispenses the conveyed liquid at least substantially opposite the direction of actuation, particularly substantially in the middle and along the middle or the longitudinal axis of the dispensing device. This allows for a simple and compact construction and universal applicability.
  • Another aspect of the present invention which can also be implemented independently consists in providing several pump chambers with elastic or flexible pump sections in order to be able to deliver the same liquid simultaneously. Particularly, the pump chambers are connected or connectable parallel to a container containing the liquid. This allows for a simple and robust construction. For example, the dispensing device can even be used if one of the pumps formed by the pump sections fails, for example due to an inlet or outlet valve that no longer opens. Moreover, the use of several pump sections or pumps allows for a reduction of the volume of the individual pump chambers so that, particularly, a shorter total height is made possible.
  • As needed, the pump sections or the pumps can also be actuated one after the other, for example over an extended period of time, and/or they can make another or continued delivery of the liquid possible upon continued actuation of the dispensing device.
  • Another aspect of the present invention which can also be implemented independently makes a provision that, in the ready-to-use state, the dispensing device is arranged on the bottom of a container and/or the dispensing direction is oriented substantially vertically downward. This too allows for a very simple and robust construction. For example, a suction line into the container can be omitted. Moreover, the emptying of the container and, particularly, an emptying of the container which is as complete as possible is supported by gravitational force. Furthermore, this allows for very simple and intuitive operation, since the dispensing device or the pump part can be operated particularly by pressing down on the dispensing device and/or the container to dispense the liquid.
  • Another aspect of the present invention which can be implemented independently consists in that the dispensing device has at least one spring element arranged separately from the pump part in order to support or bring about the returning of the pump section. This allows for a simple and robust construction and an especially secure returning of the pump section.
  • Another aspect of the present invention which can also be implemented independently consists in designing a valve element of the outlet valve of the dispensing device in a hollow fashion to dispense or conduct the liquid in the dispensing direction, particularly so that the valve element forms a dispensing opening or dispensing nozzle of the dispensing device for the liquid. In particular, no other channel, head, dispensing nozzle or the like is then connected to the valve element. Rather, the dispensing of the liquid occurs directly from the outlet valve or its valve element. This allows for a particularly simple, robust and compact construction. In particular, only a few parts are necessary, so that simple and cost-effective manufacture and assembly are made possible.
  • Another aspect of the present invention which can be implemented independently consists in that the dispensing device or its outlet valve or dispensing opening or nozzle is only opened upon initial operation. This allows for simple and uncomplicated handling and, particularly, an undesired premature running out of the liquid during storage or during transport can be prevented.
  • Another aspect of the present invention which can also be implemented independently consists in providing the dispensing device with an opening means, so that when an associated container is changed out, it is opened by the opening means and a liquid connection to the inlet valve is established. This enables simple handling.
  • The proposed dispensing device can be used, for example, for air sprayers, air fresheners or other applications, for example for dispensing a medium from a flat glass, a cup, a dish, or the like. The dispensing device can also in each case be used directly into a dish, cup or the like. Dispensing can occur optionally in liquid and/or atomized form. As needed, it is also possible to switch between the two forms of dispensing.
  • Other advantages, features, characteristics and aspects of the present invention follow from the claims and the following description of a preferred embodiment on the basis of the drawing.
  • FIG. 1 shows a schematic section of a proposed dispensing device;
  • FIG. 2 shows an enlarged section from FIG. 1;
  • FIG. 3 shows another enlarged section from FIG. 1; and
  • FIG. 4 shows another enlarged section from FIG. 1; and
  • FIG. 5 shows a section of a modified embodiment of the dispensing device corresponding to FIG. 1.
  • In the not true-to-scale, merely schematic figures, the same reference symbols are used for same or similar parts, with corresponding or comparable characteristics and advantages being achieved even if a repeated description is omitted.
  • FIG. 1 shows a proposed dispensing device 1, particularly in the form of a pump, for the dispensing of a preferably cosmetic liquid 2 in the sense named at the outset. The liquid 2 can be substantially more viscous than water or optionally even pasty.
  • A container 3 for supplying liquid 2 is preferably associated with the dispensing device 1 to which the dispensing device 1 is preferably attached or vice versa. In this manner, the container 3 or the like can be changed out and/or the liquid 2 can be refilled. Alternatively, the dispensing device 1 can also form a reservoir for the liquid 2 or the container 3 itself.
  • In the depicted example, the container 3 preferably has a collapsing bag 3 a, particularly in a rigid container 3 b. The container 3 or the container 3 b can preferably be detachably connected with the dispensing device 1 or vice versa. Particularly, the container 3 can be changed out or the dispensing device 1 can be used several times.
  • FIG. 5 shows a modified embodiment in a section corresponding to FIG. 1. Here, instead of the inner bag, a movable piston 3 c is arranged in the container 3 b.
  • When removing liquid 2, the bag 3 a collapses (FIG. 1) or the piston 3 c moves (FIG. 5). To this end, the container 3 or the container 3 b preferably has a vent opening 3 d which can be covered, for example, by a label or the like (not shown) and, accordingly, is not visible to the user. Alternatively or in addition, the vent opening 3 d can also be openable by the user or automatically through the initial use of the dispensing device 1. Alternatively, the vent opening 3 d can also be integrated into the dispensing device 1.
  • The dispensing device 1 is preferably embodied such that it is arranged in the ready-to-use state at the bottom of the container 3 and/or the dispensing direction A runs substantially vertically downward. In principle, however, the proposed dispensing device 1 can also be used in any orientation and/or with any dispensing direction A and/or also together with other containers 3 or even without a container 3.
  • Especially preferably, the dispensing device 1 has an opening means, particularly in the form of a tapping element 3 e in order to open the container 3, particularly its bag 3 a or a seal of the container 3 such as a covering foil 3 f (FIG. 5), hence establishing a liquid and fluid connection between the container 3 and the dispensing device 1, so that the liquid 2 can be removed. Especially preferably, very simple handling is made possible by the opening means, since a putting on or connecting of the dispensing device 1 with the container 3 is sufficient to open and fluidly connect the container 3.
  • The dispensing device 1 can preferably be screwed with the container 3 or container 3 b or connected in a locking manner. However, it is also possible for the dispensing device 1 to no longer be detachable from the container 3 or container 3 b. In this case, the dispensing device 1 is, for example, adhered or welded thereto and/or engaged therewith.
  • In the following, the preferred construction of the dispensing device 1 is explained particularly with reference to FIGS. 2 to 4. FIG. 2 shows, in an enlarged section of FIG. 1, the dispensing device 1 but without liquid 2 and without bag 3 a. FIG. 3 shows the dispensing device 1 in another section. FIG. 4 shows the dispensing device 1 in yet another section.
  • The dispensing device 1 preferably has a first component 4, a second component 5 and/or at least one preferably elastically deformable pump part 6 or an elastically deformable pump section 6 a—in the depicted example, three pump sections 6 a. The preferred embodiment and function of a pump section 6 a is primarily taken into account in the following. This preferably applies accordingly to the other pump sections 6 a.
  • The pump part 6 or second component 5 is connected or connectable with the first component 4 preferably in an undetachable, liquid-tight and, particularly, gas-tight manner.
  • The first and/or second component 4, 5 is preferably designed to be rigid and/or a single piece, and is particularly injection molded from a suitable, preferably food-safe plastic, particularly polyolefin, such as PP (polypropylene) or PE (polyethylene) or manufactured in another manner. The pump part 6 or the pump section 6 a, by contrast, is designed to be flexible or elastically deformable.
  • The second component 5 is preferably used to affix or hold the pump part 6. Especially preferably, the pump part 6 is formed by the second component 5 or formed thereon or vice versa.
  • In the depicted example, the second component 5 is preferably injection molded onto the pump part 6 or connected undetachably and liquid-tightly therewith in another manner. This makes simple manufacture possible, for example by means of so-called “bi-injection,” i.e. particularly by means of the injection molding of another material in the same injection mold in which a first material is formed. Particularly, a chemical and/or mechanical connection is thus made possible.
  • Alternatively or in addition, the second components can also be connected or held together with the pump part 6 by means of an undercut, recess, through hole, overlap, or the like. Moreover, the pump part 6 and the second component 5 can be embodied or manufactured as separate components.
  • Especially preferably, an accommodating or pump chamber P for the liquid 2 is formed between the first component 4 and the pump part 6 or pump section 6 a or bordered thereby at least in part.
  • Preferably, the pump section 6 a is designed to be at least substantially dome-like or hemispherical or arched and/or the first component 4 has a preferably recessed area 4 a corresponding thereto or facing same in order to form or delimit the pump chamber P. Especially preferably, the preferably single-piece pump part 6 or second component 5 has several, particularly three such pump sections 6 a which form three pump chambers P correspondingly. The first component 4 preferably has three recessed areas 4 a corresponding thereto which are indicated in FIGS. 2 to 4 as being at least substantially dome-like.
  • In the depicted example, several or all pump chambers P are preferably connected to the same or a common liquid reservoir and serve to pump and convey the same liquid 2.
  • The second component 5 is, as already mentioned, designed to be relatively rigid. By contrast, the pump part 6 or the pump parts 6—at least the pump section 6 a or the pump sections 6 a—are designed to be elastically deformable or flexible in order to make possible the desired deformation for reducing the size of the pump chamber P or the pump chambers P for the pumping or conveying of the liquid 2. The different materials, as already mentioned, are preferably connected with each other such that a single component is finally formed. This facilitates assembly considerably. In particular, it is then sufficient to connect the second component 5 with the first component 4. This is preferably done by means of ultrasound welding and/or in another suitable manner.
  • The dispensing device 1 preferably has an inlet valve 7 and an outlet valve 8. Preferably, the pump part 6 forms the inlet valve 7 and/or outlet valve 8 together with the first component 4. However, the valves 7, 8 can also be formed separately. The valves 7, 8 are preferably embodied as self-closing one-way valves.
  • When the pump chamber P is filled with liquid 2, the volume of the respective pump chamber P can be reduced starting from the resting and initial position shown in the figures through deformation of the associated pump section 6 a, hence expelling and dispensing liquid 2 from the pump chamber P. Particularly, to this end, an actuating element 9, especially preferably a surface bearing the dispensing device 1 (indicated in FIG. 2 for the same of example), a cap or the like (not shown) is moved in a direction of actuation B relative to the first component 4, particularly by pressing the dispensing device 1 or the container 3 down in the direction N, hence deforming the pump section 6 a at least in areas and reducing the size of the pump chamber P.
  • The outlet valve 8 or the nozzle 17 is preferably arranged at least substantially in the middle of the dispensing device 1 and/or between the pump parts 6 or the pump chambers P.
  • As mentioned earlier, an actuation of the dispensing device 1 or at least of a pump section 6 a, especially preferably of several or all pump sections 6 a, occurs by pressing down on the dispensing device 1 or the container 3.
  • However, it is also possible, for example, for a user (not shown) to press directly on the pump section 6 a or for another object to press or act thereon in order to dispense liquid 2.
  • Upon deformation of the pump section 6 a and reduction in the size of the pump chamber P, the liquid is dispensed or delivered via the outlet valve 8. Particularly, the opening of the outlet valve 8 occurs automatically, preferably as a result of the pressure of the liquid and/or—optionally additionally—as a result of a corresponding deformation of the pump section 6 a upon actuation.
  • In the depicted example, the outlet valve 8 is preferably arranged laterally beside the pump sections 6 a, particularly in the middle.
  • The outlet valve 8 preferably has a valve element 10 which is particularly designed to be a single piece with the pump part 6. In the depicted example, the valve element 10 is preferably held by a connecting section 11 and preferably connected with the pump part 6. The connecting section 11 surrounds the valve element preferably in an annular shape or in the form of a flange. The connecting section 11 holds the valve element 10 preferably on an associated valve seat 12 of the outlet valve 8. In the depicted example, the valve seat 12 is particularly embodied in an annular shape or as a conical ring. Especially preferably, the valve seat 12 is designed as the front surface of a recess 13 which is closed at the end and/or is formed by the first component 4, particularly molded therein.
  • The opening of the outlet valve 8 occurs particularly through axial movement of the valve element 10. This is particularly possible as a result of the elastic deformation of the connecting section 11 or of other variable areas.
  • The outlet valve 8 is preferably connected to the associated pump chamber P, preferably in a parallel manner to all pump chambers P, via a connection channel 14 and/or an annular channel 15 enclosing the valve seat 12 radially to the outside. Upon pumping or actuation of the pump part 6 or the pump parts 6, liquid 2 located in the pump chambers P is put under pressure and leads, particularly, to a deformation of the connecting section 11 which is such that the valve element 10 is lifted axially off of the valve seat 12, i.e. the outlet valve 8 opens. The liquid 2 can then flow into the recess 13, particularly radially.
  • Moreover, the dispensing device 1 preferably has a delivery channel 16 and/or a nozzle 17. Especially preferably, the delivery channel 16 and/or the nozzle 17 are formed by the valve element 10. In particular, the valve element 10 is hollow for this purpose and/or is provided with a corresponding through-channel, particularly one which runs axially or in the direction of movement or in the dispensing direction A. In place of the preferably formed nozzle 17, a flat nozzle in the depicted example, the dispensing device 1 or the outlet valve 8 or the valve element 10 can also have only a dispensing opening formed, for example, by the delivery channel 16.
  • When the outlet valve 8 is open or the valve element 10 is lifted off of the valve seat 12, the liquid 2 flowing into the recess 13 is particularly diverted and delivered through the valve element 10 or through the delivery channel 16, a dispensing opening formed thereby and/or the nozzle 17. In the depicted example, the outlet valve 8 or valve element 10 therefore are used particularly for the direct dispensing or delivery of the liquid 2. In particular, as a consequence, no other channels, diversions, delivery nozzles or the like connect to the outlet valve 8 or its valve element 10, although this is also possible in principle and, accordingly, is not intended to be excluded.
  • Especially preferably, the dispensing device 1 or its outlet valve 8 or the dispensing opening or nozzle 17 is only opened upon initial actuation. Particularly, the nozzle 17 is provided, for example, with a very thin wall 18 during manufacture in the area of its outlet opening or tip. Only upon initial actuation or dispensing of liquid does the pressure of the liquid cause the abovementioned thin wall 18 to rupture, hence opening the nozzle 17 or the liquid dispensing or the dispensing device 1. However, other constructive solutions for achieving the desired effect are also possible here.
  • The dispensing direction A preferably runs at least opposite the direction of actuation B and/or at least substantially parallel to and/or in the middle axis M of the dispensing device 1 and/or at least substantially parallel to and/or in the longitudinal axis L of the container 3 (cf. FIGS. 1 and 2).
  • After the dispensing of liquid and the respective drop in the liquid pressure in the pump chambers P or in the annular channel 15, the outlet valve 8 preferably closes again automatically, particularly as a result of the restorative forces of the connecting section 11. However, other constructive solutions are also possible here. A return spring or the like can also be used here as needed.
  • After the dispensing of liquid is completed—particularly after the pressing down of the container 3 or the dispensing device 1 has ended or after the container 3 or the dispensing device 1 has been released—there occurs a preferably automatic return of the pump section 6 a or the pump sections 6 a into the initial position shown in the figures, with new liquid 2 being taken up, preferably sucked, via the inlet valve 7 or the inlet valves 7 into the pump chamber P or the pump chambers P. The opening of the inlet valves 7 during the return to the initial position occurs particularly as a result of the negative pressure prevalent then in the pump chambers P.
  • According to a preferred aspect, the dispensing device 1 has at least one spring element 19 which is particularly arranged and embodied separately from the pump section 6 a or the pump sections 6 a and acts directly on the actuating element 9 in the return direction R—i.e. flexible in the axial direction or direction of actuation B—in order to support or bring about the return of the pump section 6 a or the pump sections 6 a.
  • Preferably, the spring element 19 is designed to be arch- or bow-like. However, any other shape is possible here.
  • Preferably, the height or axial extension of the spring element 19 corresponds substantially to that of the pump sections 6 a and/or the spring element 19 points in the same direction or in the axial direction.
  • Especially preferably, the spring element 19 is arranged on the dispensing device 1, particularly on the second component 5 or pump part 6, and is embodied as a single part therewith, preferably molded or injected thereon.
  • Preferably, several spring elements 19 are provided which are preferably distributed peripherally along the circumference of the covering device 1 and/or arranged in a diametrically opposing manner which is such that the dispensing device 1 exhibits good stability even in the case of a very long and/or heavy container 3 or container 3 b.
  • Especially preferably, the spring elements 19 are arranged radially outside and/or around the pump section 6 a or the pump sections 6 a and/or the outlet valve 8.
  • In the depicted example, the second component 5 has at least one preferably bridge-like projection 20 which engages in a groove 21 in the first component 4 and is connected therewith—particularly by means of ultrasound welding—in a liquid-tight manner.
  • Especially preferably, the second component 5 has a raised area 22 on the side opposite the projection 20 which facilitates the placement of a transmission element (not shown) for the introduction of ultrasound and hence a focusing of the ultrasound onto the desired area to be connected. The liquid-tight connection formed extends, particularly, around the pump part 6 or the pump sections 6 a.
  • In the depicted example, a separate inlet valve 7 is preferably allocated to each pump chamber P. Particularly, in this regard, a valve seat area 23 with a valve opening 24 toward the container 3 is formed for accommodating liquid 2. Moreover, a valve flap 25 is preferably arranged on the pump part 6 or separately on each, particularly embodied in one piece with the pump part 6 or formed therefrom, and particularly pretensioned in the manner of a leaf spring or elastically against the valve seat area 23 to cover or seal the valve opening 24 as indicated in FIG. 4 for a pump chamber P. The valve flap 25 therefore lies on the inside of the pump chamber P at the valve seat area 23.
  • Upon the return of the pump sections 6 a into the initial position shown in the figures, the outlet valve 8 is closed. Accordingly, negative pressure is formed in the pump chambers P, so that the valve flaps 25 open toward the outside and thus release the valve openings 24, hence opening the inlet valves 7. In the preferred arrangement of the dispensing device 1 at the lower end of the container 3, the gravitational force is conducive to the filling of the pump chambers P with the liquid 2 upon return. Moreover, emptying can be achieved at least to the greatest possible extent.
  • As needed, channels 26 can be additionally provided on the valve seat areas 23 on the outside in order to support an emptying of the container 3 which is as complete as possible.
  • Individual features and aspects of the various embodiments can often be combined with each other as desired or used in other dispensing devices or the like.
