Description

Technical area

The invention relates to a dispensing system for the portion-wise dispensing pasty, liquid, sprayable and / or foamed media according to claim 1. In a non-claimed embodiment comprises a storage cartridge with at least one, the weight counteracting force bearing surface, the output device and a, the output device comprising connecting with the supply cartridge connecting element and the cartridge receptacle at least one, connected to the housing holding means on which the support surface of the reservoir for supporting the weight of the supply cartridge can be placed, and at least one, the connecting element or the output device against the actuating force abstützendes abutment.

Furthermore, the invention relates to a second embodiment of a dispensing system in which the support surface and the holding means need not necessarily be provided, wherein the pressure for the output of the medium via an actuator disposed on the housing is manually or electrically generated by an actuating force and a, the pressure exercising area of the actuating device is transferable to a pressure-receiving area of the dispensing device and as a result of this pressure, the dispensing device dispenses portionwise a portion of the medium.

State of the art

Dispenser systems of this type are well known. Typically, such dispensing systems include a housing having a back wall that can be secured to the wall of a room. On this back wall are Holding means for attaching or holding a supply cartridge arranged, wherein the inserted cartridge is covered by a lid, which is usually pivotally connected in the upper region of the rear wall.

To output a portion of the medium to be dispensed, an actuating device is provided which can be actuated manually or electrically. In both cases, a compressive force presses on an output device, usually in the form of a pump, which usually down the portion of the medium can be delivered. The actuator may be a separate printing paste, commonly referred to as a "push-button", in other embodiments of the dispenser, however, the housing cover itself may be formed so that it simultaneously forms the actuating device via its pivotable mounting, ie with a section on the dispenser acts and can transmit a compressive force on the housing.

Depending on the medium to be dispensed the dispenser is designed differently in the rule. Thus, for example, a pump for dispensing foam has a foaming device which is capable of absorbing air in addition to the originally liquid medium, the air and the medium then being able to be swirled together and thus dispensed foamed. Dispensers for gaseous media are usually depressurized, so that here too an originally liquid portion of the medium is mixed by an appropriate design of the dispenser in the form of an aerosol with air and is issued as quasi-gaseous. For the purposes of this application, gaseous also means air streams wetted with liquids, whereby, of course, the dispensing of purely gaseous media via an output device which is connected to a pressure-filled reservoir also falls under the aspect of the invention.

The known dispensers are each capable of reliably and visually appealing the medium. However, the disadvantage of the known dispensers is that usually a special dispensing device is constructed for each type of medium. That does not just increase the Production costs, but also the storage costs or made it difficult to retrofit a dispensing system that is already installed at the customer on another medium. For example, when changing a soap dispenser from a liquid dispenser to a dispenser capable of dispensing the foamed soap, the entire dispenser or at least some parts thereof must often be exchanged therewith. Thus, a simple change of the medium for the customer is usually not possible or at least associated with considerable effort, which significantly limits the freedom of choice of the customer with respect to the media used. WO 2006/015973 discloses a dispensing system according to the preamble of claim 1.

Presentation of the invention

The object of the invention is therefore to provide a dispensing system that can be output as many media as possible at the lowest possible cost. The aim of the invention is to provide a universal dispenser for the widest possible range of media.

This object is achieved according to a first aspect of a non-claimed embodiment in that the dispenser system is designed as a common part system for the construction of dispensers for pasty, liquid, sprayable and / or foamed media, for which purpose the cartridge receptacle and the supply cartridge are designed such that Distance between the actuator and the abutment to the support surface or the bearing surfaces is the same size.

This object is achieved in terms of the invention in that the dispensing system according to claim 1 also as a common part system for building on donors for different, in particular pasty, liquid, sprayable and / or foamed media is formed, for which purpose the actuator at least two pressure-applying areas and the output device of a first reservoir cartridge having a first pressure-receiving region and the output device of a second reservoir cartridge having a second pressure-receiving region After using the supply cartridge in the dispenser cooperate with only one of the pressure-exerting area. Here are the Pressure applying areas and the supply cartridges designed such that at least two types of storage cartridges can be inserted into the cartridge receptacle and at different positions depending on the configuration and / or length of the supply cartridges either a first pressure-applying area with the first pressure receiving portion of the first supply cartridge or a second pressure applying region with the second pressure receiving portion of the second storage cartridge device at the latest during the actuating movement for transmitting the actuating force in contact.

The dispenser system according to the invention is now characterized in that supply cartridges for very different media can be used by one and the same dispensing system. The customer purchases the supply cartridge, which includes the reservoir and the dispenser. However, this output device is constructed differently consuming depending on the consistency of the medium to be dispensed. Thus, for example, the above-mentioned foam pumps must include additional means for sucking air and for swirling this air with the originally liquid medium in the reservoir. The same applies to pumps that are to issue an aerosol, whereby the medium in the reservoir is originally liquid. A pure liquid pump, however, requires only the respective pumping means, so only has to provide the stroke for the pump chamber. Usually, therefore, a foam pump will have a greater length than a pure spray pump.

The problem with most dispensers, however, is that the actuating movement for the dispenser is perpendicular to the wall surface on which the dispenser is mounted, while the dispensing direction is directed vertically downwards. This causes the operating force to press against the dispenser. In order for the pumping movement to take place, either the supply cartridge would have to be so tightly mounted in the housing and made so stable that it can absorb the pressure force and does not migrate to the rear or the output device must be within the housing on the Can support abutment. For cost reasons, the first alternative is usually not considered in a dispenser system. However, the second alternative leads to the problem that the position of the abutment is fixed within the housing, so that the distance of the actuator, so for example the push button, is firmly defined by the abutment.

Usually, the storage cartridge is inserted into the housing, wherein it rests with at least one support surface on a corresponding support surface. In this non-claimed embodiment, this support surface is arranged in the region of the center of gravity of the reservoir or above. In this way, the reservoir, stabilized by its weight, can be hung in the housing. Depending on the design of the output device, this now extends in the direction of the support surface over different distances. So that the greatest possible variation of dispensing devices can be used, the supply cartridge is designed such that the distance between the support surface on the one hand and the abutment or the actuator on the other hand is the same size. In this way, different sized dispensers can be used in one and the same dispenser.

It is particularly lucrative if the storage cartridges, regardless of the type of medium to be dispensed or the execution of the dispensing device each have a reservoir with unclaimed same dimensions. So that the supply cartridge then remains usable in the housing due to the predetermined position of the dispensing device, the connecting element is designed such that it can compensate for the different geometries of the different actuating devices. This connecting element may be formed as a separate component, but it may also be a piece connected both to the reservoir and alternatively to the output device, so be part of this assembly. The dispenser may be formed in a variety of ways.

Thus, in the case of a pump, e.g. it is possible for the actuating force to be applied at right angles to the rear wall of the housing and to be deflected within the dispenser or within the housing, so that the direction of movement of the pumping means is aligned parallel to the rear wall of the housing in the vertical direction. The abutment can be supported directly on the output device, alternatively, the connecting element can be interposed. In this case, of course, the connecting element must be sufficiently rigid so that it can endure the compressive force at least with a corresponding section. In an alternative embodiment of the dispensing device that is not claimed, the pumping means can also be moved horizontally in the actuating direction of the actuating device. Again, an output of the medium can be down, alternatively, of course, the medium can be output in the horizontal direction, such as an output channel.

If the actuator is a push button and this push button is formed in front of the pivotally mounted on the rear wall housing cover, it is expedient that the hinge, via which the housing cover is applied to the rear wall, has at least one latching possibility. By way of this, the angle section, via which the closed housing cover can be moved, can be limited such that the housing cover can only complete the actuating movement. Only after manually releasing the detent lock can then the housing cover be further pivoted to renew the supply cartridge. Such a configuration can for example be realized in that at least one resilient latching lug is provided in the housing, which is initially displaced upon closing of the housing cover by a locking edge against the elastic spring force and then engages behind the locking edge.

Such a locking edge may be formed by a protruding from the housing cover edge, wherein for opening the housing and for pivoting the housing cover in the refill position from below or through a slot with a special tool or a Conventional screwdriver, the locking lug can be pushed back against the spring direction, so that the latching connection is disengaged and the housing cover is swung open. Of course, on the housing cover or on the rear wall of the housing, a sliding element or a knob may be provided which acts mechanically on the lock, that via a corresponding operation, the lock is releasable. Here, in particular in the case of a rotary knob, this can be designed so that it can only be actuated with a special tool.

A further embodiment of the invention, which is also usable independently of the features described above, is characterized in that the different lengths of the dispensing device are compensated by the fact that the actuating device has at least two areas, via which the applied pressure from the actuating device to the dispensing device can be transferred. For this purpose, two pressure-applying areas of the actuator are provided, which are arranged offset in the direction of actuation to each other. Depending on which dispensing device is now used, one or the other pressure-applying area is used to transmit the actuating force. To accomplish this, the dispensers have different pressure-receiving areas over which the pressure of the actuator is transmitted to the respective organs of the dispenser.

Thus, a first pressure applying area communicates with a first pressure receiving area of the dispenser, while a second pressure applying area of the actuator can contact a second pressure applying area of the dispenser. However, the dispenser is each designed so that only the respective areas engage each other.

The embodiment described above can for example be realized in that the actuating device of the inside has a depression. The bottom of this depression is then the second pressure applying area, while the area around this Depression represents the second pressure applying area. A first output device has, as a pressure-receiving region, a pressure ram which projects into the depression. By contrast, the second dispenser, which, for example, because it is somewhat shorter, is used for dispensing liquid medium, has a wider pressure ram which is able to support itself on the annular space around the indentation. In this way, different length dispensers can be used with one and the same dispenser housing.

Of course, in addition to the described two pressure-exerting or pressure-receiving areas also several of these areas may be provided to use other output devices with the universal dispenser can. Alternatively, the depression could also be closed by a plug which can then be removed when using longer dispensing devices. However, this has the disadvantage that the inside of the housing cover or the actuator must first be manually prepared for the use of a special storage cartridge, which is not only associated with additional work but can also increase the error rate.

In the dispensing system of the invention, the pressure applying and pressure receiving areas move vertically. This can e.g. be realized in that initially there is a force deflection of the force generated by the moving in the direction of the rear housing actuator pressure force. Alternatively, of course, the actuator can act directly in the vertical direction. Of course, the pressure applying and receiving portions may also be provided on intermediate elements which are interposed as power transmission elements between the actuating device and the output device.

A further embodiment of the dispenser system is configured in that on the inside of the push button, a receptacle for a pressure piece is provided, which is displaceable or rotatable on the inside of the Pushbutton is arranged. This pressure piece has two surfaces which can be activated by the displacement or twisting as pressure applying surfaces. Depending on the geometry of the supply cartridge, in particular the output device, the one or the other pressure exerting surface can now be activated, which can be done either manually when inserting the supply cartridge and alternatively can be provided a Einfädelhilfe that when closing the housing cover an independent rotation or Displacement of the pressure piece causes so that a special adjustment by the refilling operator need not be made. To avoid incorrect operation, the last-mentioned embodiment will of course be particularly preferred, such a threading aid may be formed by ramps on the output device, wherein the pressure piece with contact surfaces on these ramps slides and the ramps are arranged such that they as a result of the pivoting movement of the displacement cause the pressure piece.

In the dispenser system according to the invention storage cartridges of various kinds can be used. These can be, for example, supply cartridges for dispensing pastes or liquid media, storage cartridges for foamed dispensing of liquid media contained in the storage container or also storage cartridges for dispensing sprayable media, which may be aerosols or gases from a pressureless or a pressurized medium Be discharged pressurized reservoir. Preferably, the reservoir for all storage cartridges on the same unused dimensions, so that the shape of the dispenser, in particular the geometric variations can be compensated by the connecting element.

The center of gravity of the support surface, with which the storage container rests on the support of the housing, is preferably arranged at least at the level of the center of gravity or above, so that the entire supply cartridge itself can be hooked into the housing in a stabilizing manner. In this way, a one-hand operation of the housing realized be because the refill only has to open the housing cover, and then in the open housing cover can use the supply cartridge. To facilitate this insertion of the upwardly swinging housing cover can be kept open by a spring force.

The storage container may have a support surface which is preferably formed by two opposite partial surfaces which cooperate with corresponding retaining surfaces on the rear wall of the housing. Of course, a plurality of superimposed bearing surfaces may be provided, each housing then having a corresponding number of retaining surfaces, alternatively, only one of the retaining surfaces of the housing with the recordings engage, so that the reservoir depending on the output device used at different heights in the housing can be used.

In a further embodiment of the dispenser a plurality of holding means are provided in the housing, wherein only one or only some of the holding means cooperate with bearing surfaces of the reservoir. Here, the different reservoirs of the various storage cartridges may be formed so that they can be placed only on a holding means or only a pair of opposing holding means, wherein the wall of the reservoir below and / or above this attachment position is retracted accordingly far, so that the other holding means remain inactive.

Depending on the configuration of the dispensing device, which will usually be formed by a liquid or a foam pump, here, the connecting element, the media flow vertically downwards forward or at right angles to the side or forward deflect. The connecting element itself may be formed by a rigid channel having a corresponding geometry. In a non-claimed embodiment, the connecting element may also be a flexible hose or a combination of a rigid channel and a form flexible hose section. Furthermore, the connecting element may also be part of both the storage container and alternatively part of the dispensing device.

In the housing, a corresponding surface is preferably provided for the formation of an abutment, in which either the output device or the connecting element, assuming a correspondingly rigid wall education, can support. If, for example, a pump is used as the dispensing device, which extends with a pump body running at right angles to the rear wall of the housing up to the rear wall, the abutment can be formed by a section of the housing against which this area of the dispenser can support itself. Alternatively, a separate support may be provided which protrudes from the rear wall of the housing in the direction of the dispensing device or the connecting element and which supports the connecting element or the dispensing device laterally or obliquely.

In particular, if the holding means and the receptacle of the reservoir is formed such that the reservoir is used in several heights, or if the connecting element is designed such that at a uniform insertion height of the reservoir into the housing any height differences of the output device are compensated via the connecting element can always be used with the identical part concept according to the invention always the same reservoir. This has the particular advantage that not only the dispenser housing, the housing cover and the actuator can remain the same, then identical storage containers can be used to build the individual storage cartridges. Thus, only the connecting element has to be adapted to the respective application, whereby usually the dispensing device is a finished compensated pump element, which is available on the market as an inexpensive component. In this way, a particularly inexpensive identical part concept can be realized by the invention.

Finally, the housing can be further adapted to different applications, in which also in the upper region, the housing has a passage for output means, so that the same housing can also be used when the supply cartridge is substantially inverted with the upward dispensing device in the Housing is used. In this case, as known from a stand-alone soap dispenser, the dispenser may include an upper dispensing channel to which the user presses to dispense the medium. The upper passage of the housing may be closed by a corresponding plug, unless this embodiment is desired.

Further features and advantages of the invention will become apparent from the subclaims and from the following description of preferred embodiments with reference to the drawings.

In the FIGS. 1 to 4 a first dispensing system is shown. In this dispenser system, a supply cartridge 1 is inserted into a housing 8. This storage cartridge is in FIG. 4 presented in a single part drawing.

The storage cartridge 1 consists of a storage container 3, which has bearing surfaces 7 on both sides. In the illustrated embodiment, the reservoir 3 on two bearing surfaces 7. In the lower area of the reservoir 3 is connected to a connecting element 5, which in turn is connected to the output device 2.

The output device 2 can be actuated by the user by applying a manual pressure force in the direction of actuation R to output a defined volume of a medium. For this purpose, the housing cover of the housing 8 is formed as an actuator 6. This means that the housing cover in the upper region of the housing 8 is pivotally connected to the housing rear wall, wherein the lower region of the housing cover is formed as a pushbutton, that he rests with its inside on the output device 2. Furthermore, the housing cover is adjacent to the dispensing device 2.

By compressing the dispensing device 2 in the direction of actuation R by a few angles, ie further in the direction of the rear wall of the housing 8, pivotable. This compression of the dispenser 2 then leads to the portionwise dispensing of the medium. The storage container 3 cooperates with two holding means 10, which are arranged in the rear wall of the housing, wherein for holding the storage container 3 in the vertical direction bearing surfaces 7 of the storage container 3 rest on the holding means 10. The position of the holding means 10 is best in FIG. 5 shown, which shows a further embodiment of a storage cartridge in conjunction with a similar housing.

Way (s) for carrying out the invention

The embodiment of the storage cartridge according to the FIGS. 5 and 6 differs from the embodiment according to the FIGS. 1 to 4 in that the connecting element 5 for connecting the dispensing device 2 to the reservoir 3 is formed as a pure neck with a rigid wall, the dispensing device 2 for this purpose having a T-shaped connecting piece. In contrast, in the embodiment described above according to the FIGS. 1 to 4 the connecting element 5 is formed as a flexible hose, which also causes a right-angled flow reversal of the conveyed from the reservoir 3 in the direction of the dispensing device 2 medium.

At the in FIGS. 5 and 6 illustrated embodiment of the dispenser system, the dispenser 2 is supported against a rear abutment 9, which is formed by a wall portion of the rear wall of the housing. This abutment 9 is particularly good in FIG. 7 to recognize, in which the rear wall without reservoir cartridge 1 is shown in a single part representation. A lateral emigration of the dispenser 2 and thus the slipping of the abutment 9 are prevented by an annular projection into which the Dispensing device 2 protrudes with a rear extension.

The opposite must be in the in Figure 1 to 4 illustrated embodiment of the dispenser system, the abutment 9, that is not shown here, either by a arranged in the dispensing device 2 holding element or by a longer spacer, which may then also be connected to the rear wall, are formed. FIG. 8 shows the housing rear wall of the second embodiment of the dispenser system in a single part representation, in which case the holding means 10 of the housing 8 for receiving the receptacle 7 is formed as the above region of a projecting from the wall edge of the rear wall of the housing 8.

In the FIGS. 9 to 14 two similar types of storage cartridges are shown in individual parts. FIG. 9 shows a first supply cartridge, which has a reservoir 3, which has on its right and left side wall two, the corresponding bearing surfaces 7 opposite bearing surfaces 7. In the lower area, the dispensing device 2 is arranged in the form of a liquid pump. The connecting element 5 between the reservoir 3 and the dispensing device 2 is here as an extension of the reservoir 2, which is integrally and integrally connected to the reservoir 3, formed.

FIG. 10 shows the reservoir 3 without the output device 2 from FIG. 9 in a side view, in which case in particular the formation of the connecting element 5 can be seen as an extension and a right angle bent channel. In FIG. 11 the dispenser 2 is off FIG. 9 , in the FIG. 10 is shown in an itemized view. This is a conventional liquid pump, as it is already used in the prior art.

The FIGS. 13 to 14 show an embodiment of the invention, wherein the only difference here is that the connecting element 5 is formed as a straight down channel running, which is also integrally connected to the reservoir 3. In contrast to the unclaimed embodiment of the FIGS. 9 to 11 so here is the Actuating direction R directed vertically upward, while in the unclaimed embodiment shown above, is oriented horizontally in the direction of the rear wall of the housing.

In the FIGS. 15 to 19 schematically a dispenser system is shown, which also has a housing 8, in which a storage cartridge 1 is used, for which purpose the housing 8 holding means 10, to which the reservoir 3 with the support surface 7 can be placed.

In this embodiment, the lid of the housing 8 at the same time forms the actuating device 6, wherein for this purpose the lower part of the cover of the housing 8 against the dispensing device 2, not shown here, the supply cartridge 1 is not adjustable. FIG. 15 shows the dormant state of the dispenser system without inserted cartridge. In the lower part of a square projection on the side wall of the housing cover is provided, which is engaged behind by an abutment hook, that it forms a lock 4 against the further pivoting of the housing cover in the upward direction.

In contrast, the housing cover can be pivoted by a few degrees in the direction of the rear wall of the housing in a clockwise direction, with the supply cartridge 2 being actuated when the storage cartridge 2 is inserted through this further pivoting in the direction of the rear wall of the housing. FIG. 16 shows this state when compressed output device 2 (not shown here). It can be seen here that the rectangular projection of the abutment edge of the lock 4 is displaced by the further pivoting of the cover of the housing 8 in the direction of the rear wall of the housing. As a result, the lower part of the housing cover acts as an actuating device 6.

In FIG. 17 is the same position of the housing cover shown, which is also in FIG. 15 is shown. Here, however, the barrier 4 is already deactivated by an external pressure from below. This causes the housing cover can be swung up manually or against the force of a corresponding spring in a filling position, which in FIG. 18 is shown.

In FIG. 19 in turn, releasing the lock 4 is that in FIG. 17 is marked with the detail Z, reproduced in an enlarged detail view. It can be seen that the lock 4 is formed by an elastic, connected to the rear wall hook and the cooperating, here square-shaped blocking element of the housing cover. To release the lock 4, the hook protruding in the direction of the housing cover is pushed upwards, so that the abutment area of the hook can no longer engage behind the edge of the square blocking element.

Of course, it is in the in the FIG. 19 lock shown 4 to a detailed construction, the design should also include all other forms of releasable locks that oppose in particular with an abutment edge swiveling the housing cover in the filling position, wherein the abutment edge can be disengaged by the application of an external force. For the application of this external force rotating or sliding means can be provided either on the rear wall or on the housing cover, via which either directly or after applying a tool, the filler can disable the lock. Furthermore, it is of course also possible that the lock can be pressed from below, for example by applying a dome or screwdriver or even with your fingers up.

Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to any one of the preceding claims, characterised in that the pushbutton comprises a receptacle on its inner side for fastening a first pressure piece or optionally a second pressure piece which is thicker than the first pressure piece, the end of the first pressure piece that faces away from the pushbutton forming the first pressure-exerting region and the end of the second pressure piece that faces away from the pushbutton forming the pressure elements of the second pressure-exerting region.
7. Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to any one of the preceding claims, characterised in that the pushbutton comprises a receptacle on its inner side for rotatably or slidably fastening a pressure piece, the pressure piece comprising two pressure surfaces that are offset from one another in the actuation direction (R), form the first pressure-exerting region and the second pressure-exerting region and can be displaced, by sliding the pressure piece, in such a way that, as a result of the pivot movement of the pushbutton, they abut the first pressure-absorbing region of the first reservoir cartridge (1) or the second pressure-absorbing region of the second reservoir cartridge (1) no later than during movement of the pressure piece, and move said first or second region in the actuation direction (R) upon further actuation of the pushbutton.
8. Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to any one of the preceding claims, characterised in that the housing (8) comprises a lower rest that is arranged so as to have at least one bearing surface (7) below the connection element (5) or the issuing device (2) and laterally supports the connection element (5) or the issuing device (2) by means of a side wall.
9. Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to any one of the preceding claims, characterised in that the lower rest is formed as a groove that is open at the top, the front edge of which groove is designed as a supporting edge having a supporting surface that faces away from the rear wall of the housing (8), the connection element (5) and/or a rear part of the issuing device (2) being insertable into the open groove and the issuing device (2) comprising, in a horizontal portion, a retaining edge that projects radially outwards and is supported, at least when the actuation force is applied, on the front supporting edge when the cartridge is inserted.
10. Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to any one of the preceding claims, characterised in that at least one additional retaining means (10) is arranged above or below the retaining means (1) and the reservoir container (3) is designed in such a way that it can only be placed on one of the retaining means (10), said reservoir container comprising, for this purpose, a bearing surface (7) that cooperates with said retaining means (10), while the wall of the reservoir container (3) in the region of the additional retaining means (10) is formed such that no forces can be transferred between the wall and the additional retaining means (10) at least in the vertical direction.
11. Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to the preceding claim, characterised in that the reservoir container (3) is of such a size in the vertical direction that said container can be inserted into the housing (8) at different heights so that, in order to compensate for the space requirement of a larger issuing device (2), use may be made of a reservoir container (3) inserted at a greater height or, for a smaller issuing device (2), use can be made of a reservoir container (3) inserted at a lower height.
12. Dispenser system for issuing pasty, liquid, sprayable and/or foamed media in portions according to claim 10, characterised in that the reservoir container (3) is designed in such a way that it can be placed on a plurality of retaining means (10), in particular all the retaining means, arranged in the housing (8), said reservoir container comprising, for this purpose, a bearing surface (7) which corresponds to the associated retaining means (10) in each case.
