Foam dispenser, housing and storage holder therefor

Description of the invention

The present invention relates to a reservoir assembly, in particular for liquid soap, for containing a foam dispenser and a foam dispenser for housing a removable reservoir assembly, in particular for liquid soap, in its housing.

Soap dispensers can broadly be divided into two categories. One variant includes commonly used manual dispensers consisting of a flexible stand-up container. Screwed into an opening at the top of the container is a foam pump that has a nozzle pointing downward and a suction tube at least partially extending into the container. Therefore, the pump is located above the level of the fluid reservoir and the soap is pumped upwards. At the same time, air flows into the can by supplying air in the pump to the container to prevent a negative pressure from forming in the can. Such a soap dispenser must always be used in an upright position. If it is held upside down, the soap flows out through the air supply. There is also a risk of contamination from outside entering and blocking the air supply. For these reasons, long-term use of such a pump and dispenser is usually not possible.

In another type of soap dispenser having a foam pump, the fluid reservoir is located above the level of the pump. This variety is especially suitable for placing in a bathroom or toilet. The liquid reservoir is used to hold the liquid soap and is replaceable so that the foam dispenser can be recharged. In this variant, the pump is permanently attached to the housing. For this reason, the pump is much more massive. Because the fluid reservoir is located above the level of the pump, parts of the pump are in substantially constant contact with the fluid, due to the forces of gravity, and can be damaged. Such a pump must last much longer, i.e. as long as it is needed to pump out the contents of the series of fluid reservoirs to be replaced. Replacing the pump involves replacing the entire housing and is therefore costly.

WO 95/26831 describes a fluid dispenser for dispensing foam. The device comprises a collapsible fluid container and a foam pump attached to the container outlet. The foam pump has two chambers. The first is connected to the neck of the container, and the second is placed telescopically in the first. In the collapsed state, the two chambers constitute an air chamber and a fluid chamber, each having an outlet, the outlets communicating with each other at the foam outlet. The fluid dispenser includes a housing for releasably receiving the collapsible container and the foam pump. The foam pump may be less bulky here as both the fluid reservoir and the pump can be replaced after use.

A disadvantage of the known device is that the foam pump is specially designed for this application. Such a pump is only suitable for use in one type of housing. This makes the production of the pump much less economical as it is produced in small series especially for this application. When it is desired to make different versions of the housing and reservoir assembly, for example, to provide dispensers for different types of fluid, different types of pump and housing have to be made, which makes production inexpensive.

The object of the present invention is to provide a design for a foam dispenser and a container therefor that can be manufactured more easily and efficiently.

A reservoir assembly, in particular for liquid soap, intended to be placed in a foam dispenser which comprises a fluid reservoir having an opening and a foam pump, an air pump, a fluid pump, a lockable air pump supply, a nozzle and a movable operating part, the foam pump discharging some foam. through the nozzle after actuation of the operating part in the pumping direction, moreover, the reservoir assembly comprises a coupling member connected to the foam pump, With which the removable reservoir assembly is attached to the foam dispenser, according to the invention, is characterized in that the reservoir assembly comprises an insert connected to the fluid reservoir through an opening thereof and in the assembled state the foam pump and the coupling member are connected to the fluid reservoir by attaching to the gusset.

In a preferred embodiment, the fluid reservoir has a flexible wall to which the foam pump is connected substantially hermetically.

It is preferable that the reservoir assembly also have a surrounding shell with a rigid wall suitable for hanging in the housing of the foam dispenser, the wall of the surrounding shell having a detachable portion for passage of the foam pump therethrough.

PL 200 818 B1

In the design of the canister assembly, the fastener may include a threaded neck and the foam pump should then have a mating thread therewith by which the foam pump is attached to the fastener.

Furthermore, it is preferred that the foam pump has an air passage, one end of which should then be positioned in the outer wall of the foam pump facing the fluid reservoir, the fastener then closed by the air passage.

In a preferred embodiment, the joint member can be designed as a joint joining at least the nut and the outer wall of the foam pump.

The invention, which is a foam dispenser, within the housing of which a removable tank assembly is housed according to the invention as described above, is characterized in that the removable tank assembly is attached to the housing by means of a fastener.

The housing of this dispenser, in a preferred embodiment, has an adapter into which a fastener is inserted; the intermediate and coupling are provided with at least one means for securing and locating the foam pump in the reservoir assembly.

It is preferable that the adapter has elastic means which should rest on the fastener and that the adapter also has at least one catch limiting displacement of the fastener in the adapter under the action of forces.

In a preferred embodiment, the dispenser housing is provided with a handle, mechanically in contact with the operative part of the foam pump, for transmitting the force in the pumping direction.

The handle may be coupled to the operating part, and furthermore, the foam dispenser should have elastic means supported on the housing and exerting a force against the pumping direction on the handle.

It is best if the maximum stroke of the handle in the pumping direction and / or the maximum force transmitted to the working part are adjustable.

In such a dispenser structure, the nozzle is the operative part of the pump, and the handle is provided with means for directing the nozzle.

A foam dispenser made in accordance with the invention has a closable inlet that communicates between the space outside the fluid reservoir and the air pump.

Thus, the foam dispenser has a modular structure. It becomes easy to use another pump as only the adaptation of the fastener is required. Thereby, pumps manufactured for other purposes as well, and one type of dispenser housing may be used with different types of reservoir assembly. The housing only needs to contain the adapter associated with the fastener.

Since the canister assembly of the present invention comprises a coupling member connected to the foam pump by which the foam pump is coupled to the fluid reservoir and by which the removable canister assembly can be attached to the foam dispenser, these means also provide a modular design of the canister assembly. Using the fastener it is possible, among other things, to use of existing pumps, already produced in large series. It is also possible to use different types of pump by using an adapted fastener.

The modular concept is also achieved in that the housing is provided with an adapter for receiving the coupling element, both the coupling element and the adapter having one or more means for fixing and positioning the foam pump.

By these measures it is ensured that foam always flows out of the foam dispenser in the correct direction. For example, if the user needs to keep his hand under the dispenser, the nozzle must point downward. This is automatically ensured as the reservoir with the pump and the coupling piece can only be positioned in the adapter in one way.

Preferably, the intermediate member is provided with elastic means supported on the fastener and at least one catch which holds in the intermediate member the force-applied fastener.

When the reservoir assembly needs to be replaced, the fastener is released and at least partially pushed out of the adapter by the elastic means. This provides a more comfortable removal of the reservoir assembly.

The feature that the housing is provided with a handle in mechanical contact with the operative part of the foam pump for the transmission of force in the pumping direction is also important for users of the dispenser which pumps liquid soap by exerting force on the handle. This has the advantage that the working part of the pump does not have to be handled directly. On the one hand, after 4

This allows for the provision of a handle with a larger working surface, which is more convenient to use, and on the other hand it becomes possible to isolate the pump from the environment as it does not need to be accessible to the user. In this way, contamination of the air pump supply is avoided with, for example, wet hands of the user.

On the other hand, the coupling of the handle to the working part and the elastic means in the foam dispenser supported on the housing and exerting a force against the pumping direction on the handle give the effect of the pump to return to its starting position after each pump operation, without leakage, even when the pump starts to run more unevenly at the end of its service life.

The feature of the invention that the nozzle is part of the working part and the handle has means for adjusting the nozzle ensures that the foam dispenser works in such a way that the foam always leaves the dispenser in the right direction and the user is not surprised by the foam landing next to his hands.

The deliberate use of a flexible wall in the tank assembly, to which the foam pump is connected, in principle, hermetically sealed has the advantage that it eliminates the need for any air channel to compensate the pressure inside the tank, as the tank deforms as it empties until it is finally completely empty. . Due to the hermetic connection, no soap can pass through the air channels, for example by gravity.

Since, in the embodiment of the canister assembly of the present invention, the fastener comprises a threaded neck and the foam pump includes a mating thread with which the foam pump is connected to the fastener, it becomes possible by means of the fastener to connect the pump adapted to be screwed onto the bottle with the reservoir. fluid. Such pumps are manufactured in large numbers. From an efficiency point of view, it is therefore advantageous to use them also in the present invention.

Also a feature of the invention in that the foam pump has an air passage, one end of which is arranged in the outer wall of the foam pump facing the reservoir, the coupling member being adapted to close this air conduit, enabling the pump to be connected to the fluid reservoir in such a way. with a fastener which is also suitable for hand soap dispensers where the fluid level is below the pump level, and the fluid reservoir is aerated, for example, because it is not flexible. The advantage here is that such a pump is produced in large series for use in hand soap dispensers. The use of such a pump also in the foam dispenser of the present invention is therefore effective and economical.

It is also preferred that the joint member is adapted to connect together at least two parts of the foam pump, and it also has the function of holding the foam pump together. This makes it possible to use a simpler foam pump so that its cost is lower.

The present invention will be described in detail with reference to a drawing which shows an example of an embodiment thereof; in which: Fig. 1 is a perspective view of an embodiment of the foam dispenser of the present invention, Fig. 2 is a sectional side view of the foam dispenser of Fig. 1, Fig. 3 is a longitudinal sectional view of the foam pump of the foam dispenser of Fig. 1, Fig. 4 shows a portion of the reservoir, the fastener, and the foam pump before being mounted in the reservoir according to the present invention, Fig. 5 shows a side view of the foam dispenser of Fig. 1 in an open state, Fig. 6 shows a perspective view of the foam dispenser in an open state, Fig. 7 is a detailed perspective view of a portion of the foam dispenser of the present invention showing the connection between the fastener and the housing, Fig. 8 is a rear perspective view of the foam dispenser handle of the present invention, and Fig. 9 is a sectional side view showing it being mounted in the housing.

Exemplary version of the foam dispenser 1 concerns the soap foam dispenser. Of course, also foaming agents other than soap can be dosed with this dispenser. For example, dispenser 1 can also be used to dispense foam-forming cleaners, cosmetic products, etc.

Fig. 1 shows an exemplary embodiment of a soap foam dispenser 1. It comprises a housing 2, part of which is the operating handle 3. The housing 2 and the operating handle 3 are preferably made of a plastic material, e.g. POM, PA or ASA. It is possible to make the working handle 3 from a different material than the housing 2, or in a color different than the housing 2.

PL 200 818 B1

The operating handle 3 has a window 4. The window 4 provides a view of the contents of the tank, which is filled with liquid soap. Due to the presence of the window 4, it is possible to see to what extent the tank is full. It is also possible to make it with a window in housing 2.

Fig. 1 also shows the nozzle 5 of the foam pump 6. In Fig. 1, the soap foam dispenser 1 is seen obliquely from below. Normally, the soap foam dispenser 1 is attached to a wall with its rear wall, e.g. in a toilet. The user holds both hands under the nozzle 5 and presses the operating handle 3 with the palms of his hands, with a certain amount of soap foam landing on his hand (s) via the nozzle 5.

As shown in Fig. 2, illustrating a sectional side view of the foam dispenser of Fig. 1, in use, the flat rear wall 7 of the dispenser 1 is fixed to a wall. The rear wall 7 is provided with screw holes or holes through which wall hooks can be inserted. The housing 2 houses a removable reservoir assembly with a fluid reservoir 8. The fluid reservoir 8 has a flexible wall 9, shown schematically in the drawing. The foam pump 6 is connected to the wall 9 substantially airtight, as will be explained in more detail below. The wall 9 of the fluid reservoir 8 is generally in the form of a plastic bag.

The good properties of this bag are achieved when it is made of a laminate. An example of such a laminate is a laminate comprising a PE layer, a PA layer and a second PE layer. PE has the advantage that it can be easily welded so that the insert or plug can be welded to the rim of the bag opening. PA is a material that is a good barrier to soap. Such material is very flexible. Needless to say, this type of material is only mentioned here by way of example. It is not necessary for the flexible wall 9 to be a laminate. The wall 9 may be made by co-extrusion. It is also possible to select a different material as long as it provides a good barrier to the contents of the fluid reservoir 8.

In Fig. 2, the foam pump 6 is hermetically connected to the flexible wall 9 to form one removable unit with the fluid reservoir 8. The foam pump draws liquid soap from the fluid reservoir 8 with a short suction tube 10. Due to the short suction tube 10, it is also possible to use in a dispenser of a reservoir assembly, wherein the foam pump 6 lies above the bag, without the bag having to be completely refilled on delivery. The liquid pump of the foam pump 6 can also pump air. It is however clear that by sucking the fluid through the suction tube 10, perfect operation can be ensured from the first pump movement. In the foam pump 6, foam is produced which is dispensed through the nozzle 5.

An important advantage of the present device results from the flexible wall 9 and hermetic connection to the foam pump 6. Due to the flexible wall 9 it is unnecessary to vent the fluid reservoir 8. Accordingly, no air holes in the wall 9 are needed and therefore no means are needed for preventing fluid from flowing out of the fluid reservoir 8. As fluid is pumped out of the fluid reservoir 8, the flexible wall 9 collapses. No fluid may enter the foam pump 6 from the fluid reservoir 8 other than through the suction tube 10. This is particularly important because the foam pump 6 is located below the fluid in use during use.

Fig. 3 is a longitudinal section of a foam pump 6 to illustrate the most important aspects and components of such a pump. The foam pump 6 is preferably of the type also used in hand-held bottle-shaped dispensers. Such pumps are cheap and produced in large numbers. For example, such a pump is known from US Patent 6,053,364, so that the following description will be limited to that of the aspects important to the present invention.

The foam pump 6 is activated by moving the working part 11 downwards as shown in Fig. 3. The foam then flows from the foam pump 6 through the nozzle 5, which is an integral part of the part 11. Activation of the working part 11 leads to the activation of the air annular piston 12. which moves in air chamber 13, and a fluid piston 14 that moves in fluid chamber 15. As the pistons move, the air from the air chamber 13 and the fluid from the fluid chamber 15 are forced into the mixing chamber 16 through ports 17, for example in the shape of grooves (not shown in Fig. 3) in the fluid piston 14, respectively, between the annular air piston 12 and a fluid piston 14 and through a closable opening 18 between the fluid piston 9 and the central sealing member 14. The foam exits the mixing chamber 16 through one or more foam generating elements 20 disposed between the mixing chamber 16 and the nozzle 5. The foam generating elements 20 may be in the form of perforated plates or meshes.

PL 200 818 B1

As the air ring piston 12 moves up to the starting position, a negative pressure is created in the air chamber 13. The valves 21, here in the form of holes covered with membranes, open as a result of this vacuum. Air is sucked in from outside past the working part 11, which has some play. In this way, air is supplied from the outside of the tank 8, via an air supply closed by valves 21. As air is drawn in from the outside, there is no need to supply air from the fluid reservoir 8.

Figure 4 shows how the foam pump 6 is connected to the flexible wall 9 of the fluid reservoir 8. The wall 9 is welded to the insert 22 in the opening of the reservoir 8. In principle, gluing is also possible. The foam pump 6 is connected to a fastener 23 by which a reservoir mounting assembly including a fluid reservoir 8, a foam pump 6, a fastener 23 and an insert 22 can be attached to the housing 2.

The leading edges (not shown) ensure that the parts 6, 23 and 22 are at right angles to each other and according to the longitudinal axis indicated by the dashed line. When screwing the foam pump 6 with the fastener 23, for example, a certain tightening torque should be observed to ensure the correct alignment of the foam pump 6 with the rest of the mounting assembly of the tank and housing 2.

In the embodiment shown in Fig. 4, the foam pump 6 is bolted to the fastener 23. This assembly is then pressed tightly over the gusset 22. Needless to say, other methods of attachment are also possible. Thus, it is possible to connect the pump to the fastener by means of a snap-fit ​​connection. It is also possible to make an embodiment in which the fastener is glued to or threaded onto the outlet insert. In such embodiments, also guiding means may be provided to position the pump, fastener and insert at right angles to the longitudinal axis.

In the embodiment shown in Fig. 4, the joint member 23 has a threaded neck 24 that fits the threads 25 of the foam pump 6 within its cap 26. This is a preferred embodiment of the present invention. Foam pumps with such thread 25 are produced in large numbers for screwing onto the threaded neck of a hand soap dispenser bottle. A typical example of such a pump is also the foam pump 6 shown in Fig. 3. Thus, it is possible to use the foam pump 6 both in the soap dispensers of the present invention and in such manual soap dispensers, thereby achieving the benefits of large-scale production in production.

For use in such dispensers, which generally do not have flexible walls and are used in an upright position, the illustrated foam pump 6 is provided with an air passage 28 located in the outer wall 27 of the air chamber 13 which begins in a fluid reservoir, i.e. a bottle, and is in contact with the ambient air. This serves to aerate the bottle. As mentioned above, this is not necessary for the present invention since a fluid reservoir 8 is used with a flexible wall 9. The wall 9 collapses as the fluid reservoir 8 empties. Air passage 28 is even harmful as it can be a source of contamination to the pump and soap may come out of it. In manual soap dispensers, it means that the dispenser can only be used in an upright position. In hand soap dispensers having as a bottle, this opening also forms an open communication between the foam pump 6 and the contents of the bottle. In the illustrated dispenser according to the invention, this is of minor importance since the short suction tube 10 is already guided through the insert 22 so that the soap can only flow through the suction tube 10 through the foam pump 6. However, without additional protection, contamination of the pump can still occur.

In order to nevertheless use this common type of foam pump 6, the joint member 23 has been adapted to close the air passage 28. At least part of the inner surface of the joint member 23 contacts, for this purpose, an outer wall 27 of the air chamber 13, such as the way that the air passage 28 is closed.

In the embodiment shown, the joint member 23 performs yet another important function as it is adapted to connect the nut 26 to the rest of the foam pump 6, in this case to the outer wall 27 of the air chamber 13. The joint member 23 thus plays an important role in connecting the pump parts together. foam 6. When the foam pump 6 and the fastener 23 are screwed together, the front edge 29 of the fastener 23 abuts the support area of ​​the air chamber 13 that forms part of the outer wall 27 of the air chamber 13 so that the outer wall 27 is pressed against the nut 26.

PL 200 818 B1

As you can see, incl. in Fig. 2, the foam pump 6 is in mechanical contact with the handle 3 and is actuated by the handle 3, the nozzle 5 being moved towards the fluid reservoir 8. To prevent the entire foam pump 6 from being pressed into the reservoir bag, it would not be possible to dispense foam, the foam pump 6 is rigidly mounted to the housing 2 as described below.

The fluid reservoir 8 additionally has a surrounding rectangular shell 31 made of, for example, rigid cardboard. This cover 31 facilitates the transport of the fluid reservoir 8 and its placement in the housing 2. However, embodiments are possible in which the bag has eyelets, loops or a seam with holes, so that it can be hung from the rear wall 7 from the inside.

As can be seen in figure 5, the casing 2 in fact consists of two parts, namely a base 32 and a hinged hood 33. It is also possible to make the hood 33 completely detachable. This modular design has the advantage that parts are easily replaced if damaged. Moreover, different markets can be supplied with, for example, different hoods. A design with an interchangeable handle 2 is also possible, so that the housing 2 fits not only the specific foam pump 6 shown here.

The housing 2 is provided with a detent assembly, not shown in detail in Fig. 5, to keep the hood 33 in place during normal use. When the reservoir 8 is empty, the hood 33 is released and opened and the entire reservoir assembly including the foam pump 6 is removed and replaced with a full reservoir.

Figure 6 shows a perspective view of the dispenser 1 in an open condition after mounting. In this embodiment, in which the reservoir assembly has a rigid shell 31, the reservoir assembly is simply placed on the base 32 in a shallow tray, the so-called box holder 34.

It can be seen that the foam pump 6 is, once placed in the tank assembly, attached to the housing 2 by means of a fastener 23. According to the present invention, the adapter 23 is slid into the adapter 35 and locked by two catches 36. By means of these means for locating and fixing the foam pump 6, on the one hand, the foam pump 6 is rigidly attached to the housing 2 in use, so that the force exerted by the user through the holder 3 for the foam pump 6 can be resisted. and it is unintentionally released during use. On the other hand, the orientation of the foam pump 6 is defined such that the nozzle 5 points downward and the foam lands where the user of dispenser 1 is waiting.

Differently designed connections of the fastener 23 and the adapter 35 are possible. A different type of locking of the fastener 23 is also possible. By using the fastener 23, different types of foam pump can be used in one type of housing 2. The fastener 23 forms part of the tank assembly and comes with it.

The advantages of the modular structure of the foam dispenser 1 according to the present invention should again be emphasized. Various embodiments of the present foam dispenser can be manufactured, with the same hood 33, foam pump 6, and other standard parts, but differing in the design of the adapter 35, the fastener 23 or the mounting of the fastener 23 to the adapter 35. This can be important if different types of soap are available, for example, for people with allergies, or for use in a workshop or laboratory. It is undesirable for the fluid reservoir 8 with the wrong content to be placed in the housing 2. This error can be avoided by a specially shaped adapter or catch. Then only one specific type of reservoir assembly can be placed in the housing 2.

In the embodiment shown in Fig. 6, a cutout 37, delimited by an edge 38, is provided in the shell 31 of the reservoir unit. When the housing 2 is closed, the transparent cover 39 of the window 4 in the operating handle 3 is in front of the cutout 37. Thus, a view of the contents of the fluid reservoir 8 is maintained to determine when it will be emptied.

Preferably, the rim 38 is perforated and the cutout 37 is formed after the reservoir assembly is positioned by tearing a removable portion surrounding the reservoir of the shield 31 along the edge 37. In such an embodiment, the entire reservoir assembly may be transported as a single rectangular box, the foam pump 6 being provided. inside the box. After tearing the cover 31 along the edge 38, a cutout 37 appears through which the foam pump 6 and the fastener 23 can be drawn. The foam pump and its connection to the wall 9 of the soap bag are thus protected during transport by the enclosing enclosure 31. The reservoir units are easy to pack due to the rectangular shape of the enclosure 31.

PL 200 818 B1

Figure 7 shows a perspective view of the assembly of Figure 4 just prior to insertion of the reservoir assembly into the box holder 34 that forms part of the housing 2. Figure 7 also shows a series of structural means for positioning and securing the foam pump 6 relative to the housing 2. Connector 23 has tabs 40, ribs 41 and rounded projections 42. Coupler 23 is slid into adapter 35, which in this case is integral to the handle of the box 34, and to which the tabs 36 are also attached. Each tab 36 has a recess into which one of the pawls 40 of coupler 23 fits. the foam 6 is positioned relative to the connector 23, and the connector member to the housing 2, by means of the adapter 35, the foam pump cannot be positioned crookedly in the housing 2. Thus, the foam always leaves the nozzle 5 in a downward flow.

In a preferred embodiment of the foam dispenser according to the present embodiment, the detents 36 have a second function. In this embodiment, the adapter 35 is provided with elastic means, not shown, supported on the fastener 23. The elastic means exert a force which would push the adapter 23 out of the adapter 35 if it were not held by the hooks 36. of the assembly of the fluid reservoir 8 and the foam pump 6, the latches 36 should be moved from the housing so that the coupler 23 is pushed out of the adapter 35 by the elastic means, making it easier to grip. Thus, the replacement of the reservoir assembly is greatly facilitated.

Further constructive measures for the proper orientation of the nozzle 5, in addition to those contained in the adapter 35 and the fastener 23, will be illustrated with reference to Fig. 8. This shows the operating handle 3, viewed in perspective from the rear. On its rear side, constituting the inner side of the housing 2, there are two guide ribs 44 enclosing the nozzle 5 protruding through the opening 45. Thereby it is guaranteed not only that the nozzle 5 is correctly oriented with respect to the housing 2, but also that the nozzle 5 is positioned in the correct direction with respect to the housing 2 and the foam pump 6. After the reservoir assembly has been placed in the housing 2, the nozzle 5 is closed when closed. of the hood 33, extends through the opening 45 and is enclosed by ribs 44 which, for better functioning, may have a tapering from top to bottom. Thus, any skew of the nozzle 5 is corrected.

On the rear side, the opening 45 has an edge 46. If, at the end of its service life, the foam pump 6 starts to operate with resistance, the edge 46 ensures that the working part 11 of the foam pump 6 returns to its starting position when it is actuated. Thus, the edge 46 ensures that the handle 3 functions as a kind of driver.

The handle 3 can be moved to the starting position by pulling, but in a preferred embodiment of the present invention, elastic means are mounted at the suspension points 48 of the handle 3, which ensure the automatic return of the handle 3 after an operating movement of the pump. Fig. 9 shows such an elastic element 49, which may be, for example, a bent strip of metal or a flexible plastic material. The spring element 49 is fixed on one side at the suspension 48 of the handle 3, for example by means of a screw. When the hood 33 is closed, the resilient member 49 is under tension because its other end abuts against the support area 50 of the box handle 34.

The maximum stroke and / or the maximum force transmitted to the working part 11 can be determined in various ways by appropriate selection of the material or design of the elastic element 49, or by changing the location of the suspension point 48 or the support area 50. The same effect can be achieved by moving the contact point of the handle 3 with the pump. of the foam 6, for example, by using a different adapter or fastener. Here again, the particular advantages of the modular structure of the dispenser 1 according to the present invention are apparent. With a number of modules at your disposal, you can provide many versions specially adapted to specific applications.

Fig. 9 also shows how the elastic force from the elastic element 49 is transmitted via the edge 46 to the nozzle 5 constituting, as already mentioned, an integral part of the operating part 11.

It is obvious that the embodiment of the invention as described above relates only to the exemplary solution, which is easily modified, falling within the scope of the protection of the invention, covered by the claims. Above all, however, the foam dispenser according to the present invention can be used not only for dispensing soap suds, but also other foaming substances. In addition, the dispenser is perfectly suited for use in various positions, because the soap bag is hermetically sealed and the liquid can only flow into the pump in one

PL 200 818 B1. Considering this, the foam dispenser with the fluid reservoir unit removably arranged therein does not need to be attached to a wall, for example, for its proper functioning.
