Abstract

The invention relates to a distributing device for distributing fluids containing active ingredients to the flush liquid in a toilet bowl. The device comprises a holder (1) that can be suspended from the edge of the toilet bowl and at least two separate storage containers (2, 3) for a fluid containing active ingredients that are arranged in the holder (1), wherein each storage container (2, 3) has its own outlet (4) by means of which the respective fluid containing active ingredients is distributed to the flush liquid. In order to optimize the possibility to control the distribution of the fluids containing active ingredients in existing distribution devices, the storage containers (2, 3) are protected in such a way that no flush liquid can enter inside said containers. The outlets (4) of the storage containers (2, 3) are arranged in such a way that only the fluid containing the active ingredients can come out. A partial amount of fluid containing active ingredients is distributed from each storage container (2, 3) to the flush liquid each time the toilet is flushed.

Description

Dispensing device for dispensing active fluids

The invention relates to a dispensing device for dispensing active substance fluids into the flushing liquid in a toilet bowl with the features of the preamble of claim 1.

The term active substance fluid means flowable, i.e. liquid to viscous, possibly gel-like or also pasty or granular or otherwise pourable active substance preparations with cleaning, disinfecting, deodorising, bleaching, etc. Effect (in particular described in the unpublished DE 199 30 362 A1, as well as in EP 0 775 741 A1 and EP 0 960 984 A2).

Dispensing devices of the type in question are known under the keyword “toilet basket” in various designs. Dispensing devices for a single active substance fluid are initially known. The active substance fluid is located there in a storage container which is fixedly arranged or interchangeably inserted in a holder and has an outlet opening arranged on the bottom when the storage container is attached to the holder.

In a first known dispensing device for a single active substance fluid, the active substance fluid is added via an actuating element which can be impregnated therewith and can be acted upon with the rinsing liquid (for example made of an open-cell foam) (EP 785 315 A1). Here, the outlet opening of the storage container is largely closed by pushing out a closure part of the storage container by a sealing element arranged in a fixed manner on the holder, so that only one flow path with a small cross section is available for the active substance fluid to seep out. The device works using the capillary action of the open-cell foam. A similar construction is also known with a rib plate for distribution. In both variants, it is sometimes not considered optimal that the outlet opening is in principle permanently open, that is to say, active fluid seeps out even when the toilet bowl is not used for a long time.

Another dispensing device for a single active fluid (DE 299 02 066 U1) realizes a valve-like sealing element on the storage container, which normally assumes a positively closed closed position in which the outlet opening is closed. This takes place under the effect of the weight of a valve ball acting as a sealing element. This sealing element can be adjusted against the prestressing force into a release position which slightly releases the outlet opening. An actuating element designed as a rocker and pivotably mounted on a pivot axis on the holder serves for this purpose. On one side of the axis, the confirmation element has an exposure area which has a trough-like receptacle for rinsing liquid. The arm of the confirmation element lying on the other side of the axis lies against the sealing element from below. If the flushing liquid hits the area of influence, the sealing element is lifted from the valve seat at the outlet opening via the actuating element and releases the outlet opening a little. The active fluid can seep past the sealing element from the outlet opening into the flow of the rinsing liquid flowing past or is entrained by the rinsing liquid. From the DE 199 30 362 A1, not previously published, which has already been mentioned above, a dispensing device similar to the dispensing device previously discussed is known, but as the actuating element it has a one-armed arm hinged at one end to the holder, on which the sealing element is located between the end hinged to the holder and the application area is arranged. This construction corresponds in particular to an interchangeably arranged storage container on the holder.

When using the above-described dispensing devices of the type in question, all components that get into the flushing liquid of the toilet bowl must be contained together in the active fluid. Some active ingredient However, components cannot be realized together with stable storage. For this reason, a multi-chamber delivery device has already been proposed (EP 0 960 984 A2). This known dispensing device is used to dispense at least two different or the same solid, gel-like, pasty or liquid media in liquid or aqueous form into a toilet bowl. On a holder which can be suspended at the edge of the toilet bowl is a container which has at least two independent chambers arranged next to one another for storing the media. Each chamber has a dispensing device with a dispensing tube, which has one free end that emerges via the bottom of the container into the environment and is fluidly surrounded by a cover at its other free end. The two chambers of the container can be filled with overflowing rinsing water via slot-like passages in a cover part, which then exits into the toilet bowl in the manner of a siphon or overflow via the dispensing tubes, taking the respective active ingredient with them. The separation of the chambers in the container has the advantage that different media can be used, which would otherwise have a detrimental effect on their desired effect if they were stored together in only one chamber. The consistency of the media can also differ in the different chambers.

In the dispensing device explained above, the principle of operation of known “toilet baskets” is used, according to which rinsing water overflowing from above flows into the chambers containing the active substance fluid, dissolves parts of the active substance and flows out of the chambers while being carried along. The problem is that with the siphon effect realized here, a considerable liquid level remains in the chambers. The action of the rinsing liquid on the active substance fluid in the respective chamber therefore continues even if the rinsing process has been completed for a long time. The consumption of active fluid is practically not optimally controllable.

A two-chamber dispensing device for the same or different gel-like active substance fluids (WO 92/20876 A1) is also known, in which the outlet Openings are made as perforations in the bottom of the storage containers and are permanently open. Due to the viscosity and surface tension of the gel, it cannot normally escape under gravitational force. Partial amounts of the active substance fluids can only be discharged by overflowing rinsing liquid which enters the outlet openings from below and which slightly dissolves gel near the outlet openings. In this two-chamber system it is also the case that the outlet openings are in principle permanently open, that is to say the active substance fluids either seep out or harden under the influence of the ambient atmosphere even after long periods of non-use of the toilet bowl and can then no longer be activated.

The teaching is based on the problem of optimizing the known, previously explained dispensing device for dispensing active substance fluids from at least two separate storage containers with regard to the control option for dispensing the active substance fluids.

The problem presented above is solved in a dispensing device with the features of the preamble of claim 1 by the features of the characterizing part of claim 1. According to the invention, the storage containers are protected against the ingress of rinsing liquid into their interior and only active substance fluid emerges from the outlet openings of the storage containers. This is realized in such a way that with each rinsing process a portion of the active substance fluid is released into the rinsing water from each storage container.

In order to solve the problem defined above, an embodiment of the dispensing device according to the invention is particularly expedient. A positive closure of the outlet openings is expedient in this conception, in particular for the purpose of the defined dimensioning of the partial quantities and for the purpose of protecting the active substance fluids in the storage containers if they are not used for a long time. For the implementation of the invention, the techniques of individual dispensing devices are available, which have been explained above. It is essential that two different active substance fluids either be intimately mixed prior to being released into the rinse water or, in the case of incompatible active substance fluids, can also be conducted separately until they are applied. Special considerations are devoted to the formation of the fixed plate-like distribution element or the movable plate-like actuating element on the upper side. (State of the art in this respect WO 99/66140 A; DE 199 12 217 A1).

Preferred refinements and developments of the teaching are the subject of the dependent claims.

Claim 49 with the following subclaims provides a separate teaching that can also be protected independently.

Preferred exemplary embodiments of the invention are explained in more detail below with reference to the drawing. In the drawing shows

27 shows a lower edge of a storage container for a further modified embodiment of the dispensing device according to the invention.

The dispensing device shown in FIGS. 1 to 3 serves to dispense at least two active substance fluids into the flushing liquid, which is used to flush in a toilet bowl. What is understood as active substance fluid in the sense of the teaching has already been defined in the general part of the description, it may be pointed out.

Such a dispensing device initially has a holder 1 which can be suspended from the edge of the toilet bowl and at least two storage containers 2, 3 which are provided in the holder 1 and are separated from one another, each for an active substance fluid. The active substance fluids can be matching, different, compatible or incompatible active substance fluids. There can be two storage containers for two active substance fluids or several storage containers for several active substance fluids.

Active substance fluids suitable according to the invention are, for example, fragrance phases, in particular perfumed fragrance phases. Such fragrance phases usually contain at least one fragrance, preferably perfume oil, at least one surfactant or an emulsifier and water and, if appropriate, further ingredients such as preservatives, thickeners, complexing agents, dyes, further surfactants or emulsifiers, stabilizers, limescale dissolver etc.

Also suitable according to the invention as active substance fluids are bleaching phases, in particular chlorine-containing bleaching phases, preferably bleaching phases based on hypochlorite, the bleaching phases usually being in addition to the actual one Bleach and water may contain other ingredients such as thickeners, surfactants or emulsifiers, neutralizing agents, dyes, fragrances, etc.

Further active substance fluids suitable according to the invention are lime-dissolving active substance phases, preferably acidic lime-dissolving active substance phases. Such lime-dissolving active substance phases can contain, in addition to the actual lime dissolver - preferably an organic or inorganic acid - and water, if appropriate, further ingredients such as surfactants or emulsifiers, thickeners, fragrances, preservatives, etc.

Likewise, it is possible to use highly concentrated surfactant phases, so-called “foam boosters”, as active substance fluids. Such highly concentrated surfactant phases can also contain other conventional ingredients in addition to the surfactants.

Also suitable according to the invention are active substance fluids with antibacterial and / or fungicidal and / or antiviral active substance phase, the active substance phase in addition to the antibacterial and / or fungicidal and / or antiviral active substance and water, if appropriate, further ingredients, such as, for example, surfactants or emulsifiers, thickeners, fragrances , Preservatives, etc.

It is also possible that the active substance fluids are enzyme-containing active substance phases. In addition to enzyme (s) and water, such enzyme-containing active substance phases can optionally contain further ingredients such as surfactants or emulsifiers, thickeners, fragrances, preservatives, etc.

It is equally possible that the active substance fluids used according to the invention are absorbent, in particular odor-absorbing active substance phases. In addition to the absorption medium, in particular odor absorption medium, and water, these can optionally contain other ingredients such as Contain surfactants or emulsifiers, thickeners, fragrances, preservatives etc.

According to a special embodiment, the dispensing device according to the invention offers the possibility of using combinations of different active substance fluids in the storage containers 2, 3, wherein according to a preferred embodiment one of the storage containers 2, 3 contains a fragrance phase, in particular as previously defined.

Examples of active ingredient fluid combinations to be used are perfumed fragrance phase combined with chlorine bleach (together not stable in storage), perfumed fragrance phase with highly concentrated surfactant phase (foam booster), fragrance phase with lime-dissolving, acidic active ingredient phase, fragrance phase with antibacterial active ingredient phase, different acid systems, fragrance phase combined with enzyme-containing active substance phase, perfumed acid phase combined with water-coloring phase, fragrance phase with odor-absorbing phase, perfumed acid phase with active oxygen, perfumed acid phase with active substance phase, thickened with polyacrylate etc. Of particular interest are viscous to gel-like active substance fluids with viscosities in the range of a few thousand mPas , in particular from 2000 to 5000 mPas, preferably 2500 to 3500 mPas (measured with Rotovisko LVT, spindle 2, 6 rpm, 20 ° C).

In the dispensing device shown, each storage container 2, 3 has its own outlet opening 4, through which the respective active substance fluid can be dispensed into the rinsing liquid. In contrast to the prior art forming the starting point for the teaching, it is now the case here that the storage containers 2, 3 are protected against the ingress of washing liquid into their interior. The outlet openings 4 of the storage containers 2, 3 are arranged in such a way that only active substance fluid emerges. With each rinsing process, a portion of the active substance fluid is dispensed from each of the storage containers 2, 3 into the rinsing liquid. In the exemplary embodiment shown, this is achieved in that the outlet opening 4 of the respective storage container 2, 3 in the use position, as shown in FIG. is arranged on the side. Overflowing rinsing water hits the storage container 2, 3 at the side if necessary.

There are many different options for arranging and attaching the storage containers 2, 3 to the holder 1. In the preferred embodiment to that extent, which is shown in the drawing, it is provided that the storage containers 2, 3 in the holder 1 are individually replaceable or attachable. An alternative is the storage container 2, 3 or the like by means of an adapter. to couple with each other and to be attached coupled in the holder 1. Another alternative is to couple the storage containers 2, 3 directly to one another and thus to mount them in the holder 1 in a directly coupled manner. Finally, one can also imagine to form the storage containers 2, 3 in a common, one-piece housing, for example as separate chambers in a coherent housing, and then to attach them to the holder 1. Depending on the wishes of the practice and the active ingredient fluids to be used, one or the other variant will be selected.

The storage containers 2, 3 can be individually refilled as described in the prior art (DE 299 02 066 U1, DE 199 15 322 A1) via a refill opening in each case, optionally equipped with a valve. In this case, in particular, the storage containers 2, 3 can also be fixedly attached or formed in the holder 1, that is to say choose a uniform, self-contained arrangement. However, the illustrated embodiment shows the storage containers 2, 3 as exchangeable disposable containers, which will probably be more common in practice. The illustrated and preferred exemplary embodiment shows the storage containers 2, 3 arranged next to one another on the holder 1. The same applies to an arrangement of the storage containers 2, 3 in a row. Alternatively, one could also provide to arrange the storage containers 2, 3 one above the other for the purpose of cascading product delivery.

The illustrated and preferred embodiment also shows that the storage containers 2, 3, which can be individually replaced here, in the holder 1 by inserting are attachable from above (in the position of use). Various other fastening options are possible as alternatives. For example, you could imagine pushing the storage containers 2, 3 laterally into the holder 1. One could also imagine placing the storage containers 2, 3 on the holder 1 on the side and then pivoting them into the use position about a pivot axis. Depending on the design of the outlet openings 4 and their closure technology, one or the other variant can be selected.

In principle, gels with a very high viscosity or pastes that cannot flow on their own can be used as the active ingredient fluid. In this case, it can be recommended that the storage container 2, 3 has a flexible wall section or a flexible wall as a whole and the active substance fluid contained therein is applied by pressurizing the storage container 2, 3. This pressurization can be exerted, for example, by means of a corresponding mechanism through the overflowing rinsing liquid.

It has already been pointed out above that the dispensing mechanisms which are known from the prior art for dispensing devices for a single active substance fluid can be used in principle in the multi-chamber dispensing device according to the invention. In this respect, in the present case, it is considered a constructive possibility that a plate-like distribution element is provided on the holder 1, which has an exposure area over which washing liquid flows during the washing process, the inside of the storage container 2, 3 via the outlet opening 4, possibly with an intermediate arrangement of a a free flow of the drug fluid preventing arrangement, is permanently connected to the distribution element. According to a particularly preferred embodiment, the plate-like distribution element is assigned to all storage containers 2, 3 together.

The illustrated and preferred embodiment shows a solution that works with an actively closing sealing element. Here is the floor laterally arranged outlet opening 4 of the reservoir 2; 3 closed by means of a sealing element 5. The sealing element 5 is prestressed into the closed position closing the outlet opening 4 and adjustable against the prestressing force into a release position which slightly releases the outlet opening 4.

In order to adjust the sealing element 5, an actuating element 6, which interacts with the sealing element 5, is provided, which can be acted upon with a force by the flushing liquid during each flushing process such that the sealing element 5 temporarily assumes the release position against the pretensioning force. For this purpose, the actuating element 6 has an application area 7 which is acted upon by flushing liquid during the flushing process and on which the flushing liquid thus strikes during the flushing process. The actuating element 6 is designed as a one-armed lever articulated at one end on the holder 1. The sealing element 5 is arranged on the actuating element 6 at a certain distance from the application area 7. Due to the one-armed design of the lever forming the actuating element 6 (FIG. 3), the direction of action of the force exerted by the flushing liquid is rectified with the opening direction of the sealing element 5. As a result, the sealing element 5 can move downward from the outlet opening 4 of the storage container 2; 3 take off. As a result, it is readily possible to interchangeably mount the storage container 2; 3 without any special design features.

In the exemplary embodiment shown, the sealing element 5 is arranged between the end of the actuating element 6 articulated on the holder 1 and the application area 7. The opening path of the sealing element 5 is therefore comparatively short, the opening takes place, as desired, only with a very small gap. Moreover, with a corresponding design of the sealing element 5, this gap is opened asymmetrically, namely opening more strongly in the direction of the loading area 7, so that active substance fluid preferably exits in this direction. This is the direction to the rinsing liquid with which the active fluid then mixes accordingly. The active fluid can therefore the top of the actuating element 6 run in the direction of the loading area 7 and already mixes with the overflowing rinsing liquid on this route.

It can be provided that the sealing element 5 is formed in one piece on the actuating element 6. This is particularly recommended when designing the actuating element 6 from a plastic material, in particular from a sprayable plastic. In a particularly preferred manner, the holder 1 can also consist of plastic, in particular of injection-molded plastic, preferably thermoplastic. Overall, it can be provided that the actuating element 6 is formed in one piece on the holder 1 and the pretensioning force is generated by the inherent elasticity of the confirming element 6.

The illustrated and preferred exemplary embodiment is now characterized in a special way in that the actuating element 6 is assigned to the sealing elements 5 for at least two storage containers 2, 3, preferably for all storage containers 2, 3. 1 shows a top view of the broad and plate-like actuating element 6 with the likewise broad, trough-like actuation area 7 and the small drain openings 8 recognizable therein, all in the frame-like base plate 9 of the holder 1. The arrangement of FIGS Outlet openings 4 on the storage containers 2, 3. These are namely designed asymmetrically with respect to the center of the entire dispensing device with outlet openings 4 offset overall from the center of the dispensing device (FIG. 2). This results in a concentration of the active ingredient outlet in a relatively narrowly defined area regardless of the fact that two storage containers 2, 3 are provided.

Finally, a controlled delivery of active substance fluid from the various storage containers 2; 3 can be realized in that the flow cross sections at the outlet openings 4 and / or at the sealing elements 5 can be determined and / or adjusted differently. Finally, there are a multitude of design options of the dispensing device shown in terms of design, in particular as regards the arrangement and design of the outlet openings and sealing elements. There is a parallel patent application filed by the applicant at the same time, the disclosure content of which may be pointed out. In particular, simultaneous or time-delayed dosing with the same or different concentration from the different storage containers can be realized.

The present invention is further illustrated on the basis of the following exemplary embodiments, which, however, in no way limit the invention. Various active substance fluid combinations for the storage containers 2, 3 of the dispensing device according to the invention are described in the exemplary embodiments.

According to another and independent teaching of the invention, which is reflected in claims 34 ff., It is about the design of the top of the fixed plate-like distribution element 6 ¹ or a corresponding movable plate-like actuating element 6. This will be in connection with the drawing described with reference to the fixed plate-like distribution element 6 ', which has an exposure area overflowed with rinsing liquid during the rinsing process, the interior of the storage containers 2, 3 via the outlet openings 4, possibly with an intermediate arrangement, in each case an arrangement which prevents free flow of the active substance fluid, continuously with the Distribution element 6 ¹ is connected. One can easily consider how the variants proposed here can be implemented in a corresponding manner in the case of a plate-like, movable actuating element 6. As the relevant prior art already shows (e.g. WO 99/66140 A), the plate-like distribution element 6 'on the top near a longitudinal edge for the storage container 2 or 3 has a connection point 10 for its outlet opening 4. In the exemplary embodiment shown, the connection point 10 is designed in a star-shaped / conical shape as a kind of impact tip. With a corresponding viscosity of the active substance fluid, the desired interaction results here in the sense of targeted delivery of a partial amount of the active substance fluid into the rinsing liquid.

It is provided here that the connection points 10 are arranged next to one another at a distance near the longitudinal edge and that the distribution element 6 ^* on the top side has the recesses 11 starting from the connection points 10 and extending approximately to the opposite longitudinal edge, which serve to distribute the active substance fluids into the rinsing liquid ,

So that the depressions 11 can fulfill their function of distributing the active substance fluids in the rinsing liquid, it is recommended that the depressions 11 are groove-shaped, preferably with a U-shaped, V-shaped, W-shaped or semicircular cross section or as a series of punctiform depressions or are designed as spaces between rows of punctiform or strip-like elevations. It can be provided that the recesses 11 widen or taper towards their ends.

In the exemplary embodiment of a distribution element 6 'from FIGS. 4 and 5, the depressions 11 are designed in the form of grooves, these depressions 11 widening toward their ends.

Furthermore, it can be provided that the depressions 11 are arranged straight and / or parallel to one another, radiating, curving, zigzagging, undulating or cascading. In the exemplary embodiment of FIGS. 4 and 5, the depressions run straight and parallel to one another. If one wishes to avoid premixing of the active substance fluids early, it can be provided that the depressions 11 emanating from or assigned to the various connection points 10 do not cross one another or predominantly do not cross one another.

Alternatively, it can be provided that the active ingredient fluids of the various storage containers 2, 3 are mixed / mixed relatively quickly. This then contributes to the fact that the depressions 11 emanating from different connection points 10 are arranged crossing one another or at least partially converging towards one another. Otherwise, intersecting depressions 11 can also be used.

FIGS. 4 and 5 show a particular exemplary embodiment in so far as it is already provided that the connection points 10 are connected to one another directly at least near the longitudinal edge via at least one transverse recess 12. This results in cross-mixing on a relatively wide depression 12 in the area under the storage containers 2, 3.

There are also various possibilities for the design of the distribution element 6 'or, in the alternative design variant, of the actuating element 6. It can first be provided that the distribution element 6 'or the actuating element 6 is approximately rectangular, square, round, oval or elliptical in plan view. The distribution element 6 ', for example shown in FIGS. 4 and 5, is approximately rectangular in plan view.

But you can also implement other designs with different shapes in plan view, for example, realize that the distribution element 6 'or the actuating element 6 is formed in plan view approximately shell-shaped, flower-shaped, leaf-shaped, butterfly-shaped, in the shape of a fruit slice or the like.

There are also various options for the design of the distribution element 6 ¹ in section. You are not limited to a smooth, flat shape. Inclined and corrugated shapes can also be len. In particular, it can be provided that the distribution element 6 'or the actuating element 6 is designed to be concave, convex, curved, shell-shaped, cascade-shaped or funnel-shaped in cross-section. You can also do this for each connection point 10, i.e. in sections.

With regard to the choice of material, plastic is primarily recommended for the distribution element 6 ', specifically a hygienically suitable plastic, for example polypropylene. Of course, you can also choose other materials, provided they can be set up appropriately for the purpose. In particular, a sintered material, in particular also a sintered plastic, could be recommended here which, because of its porosity, can have an additional storage function and a mixing function and the function of foaming up the flushing liquid mixed with the active substance fluid. Alternatives are of course other materials such as ceramics, glass, metal or, in a particularly extravagant variant, a suitably equipped wood.

There are further suggestions for the design of the distribution element 6 '(or the actuating element 6) in detail. First of all, it can be recommended that the number of depressions 11 on the distribution element 6 'or the actuating element 6 is between 2 and 100, preferably between 10 and 50. It should also be provided that the width of the depressions 11 on the surface is between 0.5 and 5.0 mm, preferably between 1.0 and 2.0 mm. Finally, it is recommended that the depth of the depressions 11 be between 0.2 mm and 4.0 mm, preferably between 0.5 mm and 2.0 mm.

With regard to the design of the distribution element 6 'in size, it is recommended that the total area of the distribution element 6 ¹ or the actuating element 6 is between 500 mm ² and 8000 mm ² , preferably between 2000 mm ² and 4000 mm ² .

The variants of different distribution elements 6 'shown in FIGS. 4 to 24 will be briefly explained again in detail below. FIG. 4 shows a perspective view of a distribution element 6 'with recesses 11 which are aligned parallel to one another and widen towards the ends. These all start from a wide recess 12 which runs transversely near the longitudinal edge and connects the connection points 10 to one another and which forms the Has a function of a pre-distributor and a premix.

FIG. 5 shows the top view of the distribution element 6 ¹ from FIG. 4.

Fig. 6 shows a perspective view of a further distribution element 6 ', which is basically similar to the previously explained example. Here, however, the depressions 11 are directed away from one another, so to speak arranged in a radial manner.

FIG. 7 shows an arrangement in which the depressions 11, which are assigned to the two connection points 10, are completely separated and arranged to run away from one another. Specifically, the depressions here are curved or curved and the plate is convex.

FIG. 8 shows a construction similar to FIG. 7 in that the recesses 11 also lead away from the individual connection points 10 separately. In each case, a radial arrangement of the depressions 11, which in turn widen towards their ends, is provided for themselves. It is interesting, as in FIG. 7 and in FIG. 8, moreover, that there is no transverse, wide pre-distributor.

FIG. 9 shows a variant similar to FIG. 8, but now with depressions 11 which run in a zigzag shape and predominantly do not intersect. The plate falls here laterally outwards, so that a cascade-like structure is formed. FIG. 10 shows an arrangement with undulating transverse depressions which start from two mutually parallel depressions 11 which run straight away from the connection points 10.

11 shows depressions 11 radiating from the respective connection points 10 with rows of points arranged therein.

12 shows the depressions 11 realized on the surface of the distribution element 6 'in such a way that they are formed between raised rows of points.

FIG. 13 shows surface shingles arranged one above the other on the distribution element 6 ′, which lead to a cascade-shaped arrangement of the depressions 11.

FIG. 14 shows a variant in which the distribution element 6 'is arched upward in cross-section overall, that is to say convexly, just as in the previous figure and contrary to the design in the exemplary embodiments described earlier, in which it was concave. Here, from one connection point 10 to the other, there are depressions 11 which run in an arc, that is to say converge.

Fig. 15 shows a again flat plate as a distribution element 6 ', in which the depressions 11 also converge again, here starting from the previously explained, directly transverse, wide depression 12 between the connection points 10, but the depressions 11 overall approximately angular running and initially widening, tapering towards the end. It is also interesting here to have a central, wide additional depression which runs to the opposite longitudinal edge of the distribution element 6 '. FIG. 16 again shows a distribution element 6 ′ with a rather convex cross section with recesses 11 that run essentially at an angle and are otherwise similar to the previous exemplary embodiment. 17 each shows a depression 11 which runs from the respective connection point 10 to the opposite longitudinal edge and which is additionally structured by transverse depressions 11.

18 shows a configuration of the depressions 11 which has already been explained per se with an overall convex cross-sectional shape of the distribution element 6 ', but the distribution element 6' in plan view with an approximately shell-like shape.

FIG. 19 shows a top view of a distribution element 6 'with a more leaf-like shape, here the depressions 11 arranged crossing one another.

FIG. 20 shows an arrangement similar to the previous exemplary embodiment, but in which the depressions 11 run in an arc shape, but also intersect.

FIG. 21 shows an embodiment of a distribution element 6 'with a particularly large number of depressions 11 which are arranged and executed in an arc shape and crossing one another.

22 shows a distribution element 6 'with straight, but network-like depressions 11, which partially widen or taper and thereby have an additional structure superimposed on them.

FIG. 23 also shows a flat distribution element 6 ', in which the similar structure of the depressions 11 is realized by following rows of points between which the depressions 11 are located.

FIG. 24 corresponds to FIG. 16, only with a concave instead of a convex curvature of the plate.

It has already been mentioned several times above that in the multi-chamber delivery device according to the invention, the delivery mechanisms are basically Set can be used, which are known for the delivery devices for a single drug fluid from the prior art.

According to another, independent teaching of the invention, the present patent application also relates to a dispensing device which has been optimized while taking into account the dispensing of several or at least two active fluid, but can also be used as a dispensing device for a single active fluid.

In this respect, FIG. 25 shows a particularly expediently designed flushing plate, that is to say a fixed distribution element 6 ', which is again designed like a plate. In this dispensing device, two storage containers 2, 3 provided in the holder 1 are provided. But you can also imagine from a purely structural point of view that this arrangement can also be implemented with only one storage container 2.

It is provided here that the distribution element 6 'on the upper side in a connection area 14, starting from a longitudinal edge 13, in which a connection point 10 for the outlet opening 4 of the storage container 2; 3 is arranged and, on the other hand, the loading area 7 ′ which extends from the connection area 14 essentially to the opposite longitudinal edge 15 is divided and that the surface in the connection area 14, apart from individual elevations, depressions or openings, for reasons of fastening technology, connection technology or sealing technology, is smooth. It has been shown that the smooth upper side of the distribution element 6 'when the gap between the lower edge of the outlet opening 4 of the storage container 2; 3 and the top of the distribution element 6 'allows a sufficient distribution of the active substance fluid and a sufficient loading of the loading area 7 ¹ . The tests carried out in the prior art with all conceivable shapes in the connection area 14 have therefore not proven to be absolutely necessary if other parameters of the overall arrangement are expediently set. The exemplary embodiment shown in FIG. 25 does not show a smooth surface everywhere in the connection region 14, but a smooth surface with the exception of such elevations, depressions or openings which are present for reasons of fastening technology, connection technology and sealing technology. It is essential that the surface over which the active substance fluid is distributed is a smooth surface, that is to say has neither ribs nor grooves, nor is it a porous plate.

The circular points recognizable in FIG. 25 serve to fasten this distribution element 6 'to the holder 1, not shown here.

The illustrated embodiment shows the plate-like distribution element 6 'for both storage containers 2, 3 together. For this purpose, the connection points 10 for the outlet openings 4 of the storage containers 2, 3 are then spaced apart from one another in the connection area 14. Especially when mixing different active substance fluids, the constructive solution shown here for the distribution element 6 'has proven to be expedient in practice.

25 further shows that there is a wide strip of smooth surface of the connection region 14 between the outer edge of the connection point 10 and the application region 7 '.

So that the entire connection area 14 of the distribution element 6 'is free of ribs, grooves etc. and has an overall smooth surface.

The illustrated and in this respect preferred exemplary embodiment shows the connection points 10 again in the form of a kind of push-on tip, as has already been shown in the previously described exemplary embodiments.

The illustrated and preferred exemplary embodiment with a fixed distribution element 6 ', which is shown in FIG. 25, is now further characterized by this from that the arrangement preventing the free flow of the active substance fluid has a spacer arrangement which surrounds the impact tip or the like at the connection point 10 and is ring-shaped here, which consists of individual spacers 16 slightly protruding from the surface in the connection region 14, on which the lower edge 17 of the connection opening 4 of the storage container 2; 3 gets up. 25 shows the spacers 16 which are arranged in a ring around the push-on tip at the connection point 10 and which are arranged and leave such gaps between them that the lower edge 17 of the outlet opening 4 of the storage container 2; 3 can sit there and the active substance fluid between the spacers 16 can emerge laterally. At the same time, entry areas for back into the storage container 2 are also formed; 3 flowing air. This is the classic, dynamic interaction of viscous active fluid and air as is known in the prior art (US 4,995,555 A; EP 0 785 315 A1). The spacers 16 here provide a particularly expedient constructive solution to the exchange required overall for the function of the dispensing device.

An alternative also consists in that, as shown in FIG. 27, the lower edge 17 of the outlet opening 4 of the storage container 2 is designed as a spacer arrangement with individual, slightly axially protruding spacers 16 'which, when the storage container 2 is mounted, on the Sit on top of the distribution element 6 'in the connection area 14. Then there are the spacers 16 'on the lower edge 17 of the storage container 2; 3 hiked.

The preferred embodiment shown in FIG. 25 also shows that the distribution element 6 'in the application area 7' has depressions 11 which extend from the edge of the connection area 14 and extend approximately to the opposite longitudinal edge 15, which are used to distribute the active ingredient fluid or the active ingredient fluids into the Serve rinsing liquid. Here there are all possible configurations which have already been mentioned above for such depressions 11. The illustrated embodiment shows in parallel depressions 11 running towards one another. These have been known from the prior art for decades.

FIG. 26 shows a vertical section through a dispensing device which has a distribution element 6 ′ as shown in FIG. 25. It can be seen here that the holder 1 has a carrier 18 which holds the storage container 2 or the storage containers 2, 3, a front wall 19 facing the loading area 7 'running at the transition from the connection area 14 to the loading area 7'. The front wall 19 of the holder 1 serves to shield the storage containers 2, 3 against unwanted water entry. It is therefore recommended that the depressions 11 extend to below the edge of the front wall 19 in order to form the narrowest possible gap here, through which no water can enter. The negative consequences of an unwanted entry of water into the storage containers 2, 3 have already been described in detail above and are also the subject of extensive analyzes in the prior art.

25 shows the position of the front wall 19 of the holder 1 in relation to the depressions 11 in the loading area 7 'of the distribution element 6'. Fig. 26 also makes it clear that in the embodiment shown here, the carrier 18 is not an integral part of the holder 1, but is a separate insert part which is inserted into the holder 1. The front wall 19 is formed here on the holder 1. If the carrier 19 is an integral part of the holder 1, the front wall 19 is of course formed on the holder 18.

It is preferably provided that there is only a small gap between the uppermost edge of the depressions 11 in the loading region 7 'and the edge of the front wall 19, preferably a gap of 0.1 to 0.4 mm, in particular a gap of approximately 0.2 to 0.3 mm. This is shown in Fig. 26.
