Description

The invention relates to a delivery device for delivering active substance fluids into the rinsing liquid in a toilet bowl having the features of the preamble of claim 1.

The term active ingredient fluid means flowable, that is liquid to viscous, possibly gelatinous or pasty or granular or otherwise pourable active substance preparations with cleansing, disinfecting, deodorizing, bleaching and the like. Effect (especially described in the non-prepublished DE 199 30 362 A1 , as well as in the EP 0 775 741 A1 and the EP 0 960 984 A2 ).

Dispensers of the type in question are known under the heading "toilet bowl" in various designs First, dispensing devices for a single drug fluid are known. The drug fluid is there in a fixed in a holder or interchangeable used reservoir with a mounted on the holder reservoir bottom outlet opening.

In a first known dispensing device for a single active substance fluid, the active substance fluid is added via an actuating element (eg made of an open-cell foam) which can be impregnated therewith and acted upon by the irrigation fluid ( EP 785 315 A1 ). Here, the outlet opening of the reservoir after expulsion of a closure member of the Vorratsbehalters of a holder fixedly arranged on the sealing element is largely closed, so that only a flow path with a small cross-section for leakage of the active ingredient fluid is available. The device works by utilizing the capillary action of the open cell foam. A similar construction is also known with a distribution ribbed plate.

In both variants, it is occasionally perceived as not optimal that the outlet in principle is permanently open, so even with prolonged non-use of the toilet bowl active fluid seeped out further.

Another delivery device for a single drug fluid ( DE 299 02 066 U1 ) realized on the reservoir a valve-like arbeltendes seal member which normally assumes a positive closed closed position in which the outlet opening is closed This is done under the action of the weight of a force acting as a sealing element valve ball. This sealing element can be adjusted against the biasing force in the outlet opening a little releasing release position. Serves as a rocker trained, on a pivot axis on the holder pivotally mounted actuator. On one side of the axle the confirmation element has a loading region having a trough-like receptacle for rinsing liquid. The lying on the other side of the axis arm of the confirmation element is applied to the bottom of the sealing element. If the rinsing liquid hits the area of influence, the sealing element is lifted off the valve seat at the outlet opening via the actuating element and releases the outlet opening a little. The active substance fluid can infiltrate past the sealing element out of the outlet opening into the passing stream of the rinsing liquid or is entrained by the rinsing liquid. From the above already mentioned, not previously published DE 199 30 362 A1 a dispenser similar to the previously discussed dispensing device is known, but as an actuating element has a one-armed, hinged at one end to the holder lever on which the sealing element between the handle-hinged end and the loading area is arranged. This construction corresponds in particular to a replaceable on the holder arranged reservoir.

When using previously explained dispensing devices of the type in question, all components that get into the rinsing fluid of the toilet bowl, must be common-contained in the active fluid. However, some active ingredient components can not be realized together in a storage-stable manner. Therefore, a multi-chamber dispenser 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 in a toilet bowl. On a suspendable on the edge of the toilet bowl holder is a container which has for storing the media at least two juxtaposed independent chambers. Each chamber has a dispenser with a dispensing tube, which exits with its one free end over the bottom of the container into the environment and at its other free end fluid leading surrounded by a cover. The two chambers of the container can be filled via slit-like passages of a cover part of overflowing rinse water, which then exits the dispensing tube in the manner of a siphon or upper reaches the delivery tube taking the drug in the toilet bowl The separation of the chambers in the container has the advantage that different media can be used, which have otherwise been detrimentally influenced in their desired effect in a common storage in only one chamber. The consistency of the media may vary in the different chambers.

In the previously described dispensing device, the principle of operation known "toilet bowl" is used, after flowing from above overflow rinse water flows into the fluid containing chambers, parts of the drug substance dissolves and flows with this entrainment from the chambers again. The problem is that with the siphon effect realized in the chambers, a considerable amount of liquid remains behind. The action of the rinsing liquid on the active substance fluid in the respective chamber thus continues, too when the rinse has been completed for a long time. The consumption of active substance fluid is practically not optimal to control.

Also known is a two-chamber dispenser for the same or different, gel-like drug fluids ( WO 92/20876 A1 ), in which the outlet openings are designed as bottom-side perforations in the storage containers and are permanently open. Due to the viscosity and surface tension of the gel, this normally can not escape by itself under gravitational force. Only by overflowing rinsing liquid, which enters the outlet openings from below and which slightly dissolves the outlet openings near gel, subsets of the active substance fluids can be discharged. In this two-chamber system, it is also the case that the outlet openings are basically open permanently, so even with prolonged non-use of the toilet bowl the Wirkstöfffluide either seep out or harden under the influence of the ambient atmosphere and then are no longer activated.

A generic dispensing device is in the US-A-3,946,448 In this known device, an active substance fluid is transported from a central storage tank to individual storage containers that can be fixed to the edge of the toilet bowl, which are always provided with their own holders.

The teaching is based on the problem to optimize the known, previously explained dispensing device for dispensing active fluid from at least two separate reservoir with respect to the control option for the delivery of the active fluid.

The above-indicated problem is solved in a dispensing device having the features of the preamble of claim 1 by the features of the characterizing part of claim 1. According to the Vorratsbehalter are protected against the ingress of flushing liquid into their interior and exits from the outlet openings of the reservoir only active fluid. This is realized in such a way that with each flushing operation, the delivery of a subset of the active substance fluid from each reservoir takes place in the rinse water

For the realization of the invention, the techniques of single dispensers, which have been explained above, are suitable. It is essential that two different active fluids before their release into the rinse water either intentionally intimately mixed or incompatible drug fluids can be performed separately until the application. The design of the fixed plate-like distribution element or the movable plate-like loading element at the top are given special consideration. (State of the art insofar WO 99/66140 A ; DE 199 12 217 A1 ).

In the Fig. 1 to Fig. 3 illustrated dispensing device serves to deliver at least two active ingredients in the rinsing liquid, with which is rinsed in a toilet bowl. What is understood in the meaning of the teaching as drug fluid has already been defined in the general part of the description, it should be pointed out.

Such a dispensing device initially has a holder 1 which can be suspended at 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 each other, for one active substance fluid in each case. The drug fluids may be matched, different, compatible or incompatible drug fluids. There may be two reservoirs for two drug fluids or multiple reservoirs for multiple drug fluids.

Such active substance fluids are, for example, fragrance phases, in particular perfumed fragrance phases. Such fragrance phases usually contain at least one perfume, preferably perfume oil, at least one surfactant or an emulsifier and water and optionally further ingredients such as preservatives, thickeners, complexing agents, dyes, other surfactants or emulsifiers, stabilizers, Decalcifier etc.

Also suitable according to the invention as active substance fluids are bleaching phases, in particular bleach phases containing chlorine, preferably bleaching phases based on hypochlorite, wherein the bleaching phases usually contain, in addition to the actual bleaching agent and water, further ingredients such as thickeners, surfactants or emulsifiers, neutralizing agents, dyes. Fragrances etc. may contain.

Further active substance fluids suitable according to the invention are lime-dissolving active substance phases, preferably acidic lime-dissolving active substance phases. Such lime-solubilizing active substance phases may contain, in addition to the actual lime solubilizer-preferably an organic or inorganic acid-and water, if desired, 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 may also contain other conventional ingredients in addition to the surfactants.

Also suitable according to the invention are active-ingredient fluids having an antibacterial and / or fungicidal and / or antiviral active phase, wherein the active-substance phase, in addition to the antibacterial and / or fungicidal and / or antiviral active and water, optionally further ingredients, such as, for example, surfactants or emulsifiers, thickeners, fragrances , Preservatives, etc. may contain.

Furthermore, it is 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 may optionally contain further ingredients such as surfactants or emulsifiers, thickeners, fragrances, preservatives, etc.

Likewise, it is possible that the active substance fluids used according to the invention are absorbent, in particular odor-absorbing, active-substance phases. These may, in addition to the absorbent, in particular odor absorption mortar, and water optionally further ingredients such as surfactants or emulsifiers, thickeners, fragrances, preservatives, etc. included.

In the dispensing device according to the invention, combinations of different active substance fluids are contained 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 defined above.

Examples of active substance fluid combinations to be used are perfumed fragrance phase combined with chlorine bleach (together not storage-stable), perfumed fragrance phase with highly concentrated surfactant phase (foam booster), fragrance phase with lime-dissolving, acidic active phase, fragrance phase with antibacterial active ingredient phase, different acid systems, combined fragrance phase 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 of 2000 to 5000 mPas, preferably 2500 to 3500 mPas (measured with Rotovisko LVT, spindle 2, 6 rpm 20 ° C).

In the case of the dispensing device illustrated, each storage container 2, 3 has its own outlet opening 4, via which the respective active substance fluid can be dispensed into the rinsing liquid. Unlike in the starting point for teaching forming prior art, it is now so that the reservoir 2, 3 are protected against the ingress of flushing liquid into their interior. The outlet openings 4 of the reservoir 2,3 are arranged so that only active fluid exits. In each rinse, the delivery of a subset of the active substance fluid from each of the reservoir 2, 3 in the rinsing liquid in the illustrated embodiment, this is realized in that the outlet opening 4 of the respective reservoir 2, 3 in the use position, as shown in FIG Fig. 2 , arranged on the bottom is overflowing rinse water meets at most laterally on the reservoir 2, 3rd

In the dispenser according to the invention, the storage container 2, 3 by means of an adapter or the like. coupled together and so coupled in the holder 1 to install. An alternative is to couple the storage containers 2, 3 directly to one another and thus to mount directly coupled in the holder 1:

One can the reservoir 2, 3 as described in the prior art ( DE 299 02 066 U1 . DE 19915 322 A1 ) in each case via a refill opening, possibly equipped with a valve, make individually refillable. In particular, in this case, you can also attach or form the reservoir 2, 3 in the holder 1, so choose a uniform, self-contained arrangement. However, the illustrated embodiment shows the reservoir 2, 3 as exchangeable disposable containers, which will probably be more common in practice. The illustrated and preferred embodiment shows the reservoir 2.3 on the holder, arranged side by side. The same applies to an arrangement of the reservoir 2, 3 in a row. Alternatively, it could also be provided to arrange the storage containers 2, 3 one above the other for the purpose of a cascaded product delivery.

In principle, it is possible to use, for example, very high viscosity gels or pastes which are not independently flowable as the active substance fluid. In this case, it may be recommended that the storage container 2, 3 has a flexible wall portion or a total of a flexible wall and an application of the active substance contained therein by pressurizing the reservoir 2, 3 takes place. This pressurization can be exercised for example via a corresponding mechanism by the overflowing rinsing liquid.

It has already been pointed out above that in the multi-chamber dispensing device according to the invention, the dispensing mechanisms known in principle for dispensing devices for a single active substance fluid of the prior art can be used. In that regard, applies in the present case as a constructive possibility that the holding. 1, a plate-like distribution element is provided, which has an overflow in the rinsing process of rinsing fluid, wherein the interior of the reservoir 2, 3 via the outlet opening 4, optionally with an intermediate arrangement of a free flow of the active substance 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 operates with an actively closing sealing element. Here, namely, the bottom side arranged outlet opening 4 of the reservoir 2, 3 closed by means of a sealing element 5. The sealing element 5 is biased into the closing position closing the outlet opening 4 approximately counter to the biasing force in a release opening 4 a little releasing release position adjustable.

To adjust the sealing element 5 cooperating with the sealing element 5 actuating element 6 is provided, which is temporarily such a force acted upon in such a way with each flushing by the rinsing liquid, that the sealing element 5 temporarily assumes the release position against the biasing force. For this purpose, an actuation element 6 acts on an impingement process of flushing fluid applied to the actuation element 7, so that the flushing fluid impinges during the flushing process. The actuator 6 is designed as a one-armed, at one end hinged to the holder 1 lever. The sealing element 5 is arranged on the actuating element 6 at a certain distance from the loading area 7. Due to the one-armed design of the actuating element 6 forming lever ( Fig. 3 ), the direction of action of the force exerted by the rinsing liquid force is rectified with the opening direction of the sealing element 5. This allows the sealing element 5 down from the outlet port 4 of the reservoir 2, 3 stand out. This makes it readily possible to attach the reservoir 2, 3 interchangeable without special design features.

In the illustrated embodiment, the sealing element 5 is arranged between the hinged to the holder 1 end of the actuating element 6 and the loading area 7. The opening path of the sealing element 5 is thus comparatively low, the opening is as desired only with a very small gap. Moreover, this gap is opened asymmetrically with a corresponding design of the sealing element 5, namely, more strongly opening in the direction of the loading region 7, so that active substance fluid preferably exits in this direction. This is the direction of the rinsing liquid with which the active substance fluid then mixes accordingly. The active substance fluid can thus run on the upper side of the adjusting element 6 in the direction of the loading region 7 and already mixes with the overflowing rinsing liquid on this route.

It can be provided that the sealing element 5 is integrally formed on the actuating element 6. This is recommended in particular in the design of the actuating element 6 made of a plastic material, in particular of plastic spritzfähigem. Also, the holder 1 may be made of plastic, in particular of plastic, preferably plastic, preferably thermoplastic material in a particularly preferred manner. Overall, it can be provided that the actuating element 6 is integrally formed on the holder 1 and the biasing force is generated by the inherent elasticity of the confirmation element 6.

The illustrated and preferred embodiment is characterized in a special way by the fact that the actuating element 6, the sealing elements 5 for at least two reservoir 2, 3, preferably for all reservoir 2, 3, is assigned together. One recognizes in Fig. 1 in the plan view, the wide and plate-like running actuator 6 with the also wide, trough-like Beaufschlagungsbereich 7 and the he-identifiable small drain holes 8, all in the frame-like bottom plate 9 of the holder 1. It is coordinated the arrangement of the outlet openings 4 to the storage containers. 2 3. These are namely made asymmetrically with respect to the center of the entire dispensing device with the center of the dispenser total offset outlet openings 4 (FIG. Fig. 2 ). This results in a concentration of the active substance leakage to a relatively narrow range regardless of the fact that two reservoirs 2, 3 are provided.

It is finally possible to realize a controlled release of active substance fluid from the various storage containers 2, 3 in that the flow cross sections at the outlet openings 4 and / or at the sealing elements 5 can be differently determined and / or adjusted.

Finally, there are a variety of design possibilities of the dispenser shown in a constructive respect, in particular as regards the arrangement and design of the outlet openings and sealing elements. For this purpose, there is a simultaneous filed parallel patent applications of the applicant, may be pointed to the disclosure content. In particular, one can realize a simultaneous or time-delayed dosing with the same or different concentration from the various storage containers.

The present invention will be further illustrated by the following embodiments, which by no means limit the invention. In the exemplary embodiments, various active substance fluid combinations for the storage containers 2, 3 of the dispensing device according to the invention are described.

After further and independent teaching of the invention, which is reflected in the claims 34 et seq., It is about the design of the top of the fixed plate-like distribution element 6 'and 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 'having an overflow during rinsing of rinsing liquid Beaufschlagungsbereich, wherein the interior of the reservoir 2.3 via the outlet openings 4, optionally with interposition of each one of a free flow of the active substance fluid preventing arrangement permanently with the distribution element. 6 'communicates. One can easily consider how to implement the variants proposed here in a plate-like, movable actuator 6 in a corresponding manner.

As already shown in the relevant prior art (eg WO 99/66140 A ), the plate-like distribution element 6 'on the upper side near a longitudinal edge for the reservoir 2 and 3, a connection point 10 for the outlet opening 4 on. In the illustrated embodiment, the connection point 10 is star-shaped / conical designed as a kind Aufstoßspitze. With the appropriate viscosity of the active substance fluid, the desired interaction results here in the sense of a targeted delivery of a subset of the active substance fluid into the rinsing fluid.

It is now provided here that the connection points 10 are arranged adjacent to each other near the longitudinal edge and that the distribution element 6 'on the upper side of the connection points 10 and starting approximately to the opposite longitudinal edge reaching recesses 11, which serve to distribute the drug fluids in the rinsing liquid ,

So that the recesses 11 can fulfill their function of distributing the active fluid in the Spülflussigkeit meaningful, it is recommended that the wells 11 grooved, 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 stripe-shaped elevations. It can be provided that the recesses 11 widen or taper towards their ends.

In the embodiment of a distribution element 6 'of 4 and FIG. 5 the recesses 11 are groove-shaped, with these recesses 11 widening towards their ends.

Further, it can be provided that the recesses 11 are arranged straight and / or parallel to each other, radially, curved, zigzag-shaped, wave-shaped or cascade-shaped. In the embodiment of 4 and FIG. 5 the recesses are straight and parallel to each other.

If one wishes to avoid an early premixing of the active substance fluids, it can be provided that the depressions 11 originating from the various connection points 10 or not assigned to them do not intersect or do not predominantly cross each other.

Alternatively, it can be provided that the active substance fluids of the various storage containers 2, 3 are premixed relatively quickly. This is helped by the fact that the outgoing from different connection points 10 recesses 11 are arranged crossing each other or at least partially converging. Also otherwise intersecting recesses 11 can be used.

4 and FIG. 5 show as far as a special embodiment as already provided that the connection points 10 are connected near the longitudinal edge directly via at least one transverse recess 12 with each other. This results in a cross-mixing on a relatively wide recess 12 in the area under the storage containers 2, 3rd

For the design of the distribution element 6 'or, in the alternative design variant of the actuating element 6, there are also various possibilities. It can initially be provided that the distribution element 6 'or the actuating element 6 in plan view is approximately rectangular, square, round, oval or elliptical. That in the 4 and 5 For example, shown distribution element 6 'is formed in plan view approximately rectangular.

But you can also realize other designs with other shapes in plan view, for example, realize that the distribution element 6 'or the actuator 6 in plan view about shell-shaped, flower-shaped, leaf-shaped, butterfly-shaped, after the shape of a fruit slice o. The like. Is formed.

For the design of the distribution element 6 'in section, there are also various possibilities. One is not committed to a smooth flat shape. The term "plate-like" may also include inclined and undulating shapes. In particular, it can be provided that the distribution element 6 'or the actuating element 6 as a whole is of concave, convex, cross-section, curved, shell-shaped, cascade-shaped or funnel-shaped running is designed. This can also be realized per connection point 10, ie in sections.

With regard to the choice of material is recommended for the distribution element 6 'primarily plastic and that a hygienically suitable plastic, such as polypropylene. Of course, you can also choose other materials, as long as they can be adapted to suit the purpose. In particular, a sintered material, in particular a sintered plastic, which due to its porosity may have an additional storage function and a mixing function and the function of foaming the rinsing fluid mixed with active substance fluid, could be recommended here. Alternatives are, of course, other materials such as ceramic, glass, metal or, in a particularly extravagant variant also a suitably equipped wood.

For the design of the distribution element 6 '(or the actuator 6) in detail, there are other proposals. First, it may be recommended that the number of recesses 11 on the distribution element 6 'or the actuator 6 is between 2 and 100, preferably between 10 and 50. It should further be provided that the width of the recesses 11 at 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 recesses 11 is 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' or the actuating element 6 between 500 mm ² and 8000 mm ² , preferably between 2000 mm ² and 4000 mm ² .

The in the 4 to 24 illustrated variants of various distribution elements 6 'will be explained again briefly in detail below.

Fig. 4 shows a perspective view of a distribution element 6 'with parallel aligned extending to the ends widening recesses 11. These all go from a near the longitudinal edge transversely, the connection points 10 interconnecting wide recess 12, the function of a pre-distributor and a Pre-mixing has.

Fig. 5 shows the top view of the distribution element 6 'from Fig. 4 ,

Fig. 6 shows a perspective view of another distribution element 6 ', which is similar in principle similar, as the example explained above. Here, however, the recesses 11 are directed away from each other, in a sense arranged radially.

Fig. 7 shows an arrangement in which the recesses 11, which are assigned to the two connection points 10, completely separated and arranged away from each other. In detail, the recesses here arc-shaped or curved and the plate is convex

Fig. 8 shows one Fig. 7 so far similar construction, as well as the wells 11 lead away from the individual connection points 10 separately here. In each case here is a radial arrangement of the recesses 11, which in turn widen to their ends, provided. Interesting is like at Fig. 7 and at Fig. 8 moreover, that it lacks the transverse wide distribution manifold.

Fig. 9 shows one Fig. 8 similar variant, but now with zigzag running, mainly not intersecting depressions 11. The plate here falls laterally outward, so that forms a cascade-like structure.

Fig. 10 shows an arrangement with wave-shaped transverse recesses, which emanate from two mutually parallel from the connection points 10 straight away recesses 11.

Fig. 11 shows radiating from the respective connection points 10 outgoing recesses 11 with rows of dots arranged therein.

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

Fig. 13 shows roof tile-like stacked surface pieces on the distribution element 6 ', which lead to a cascade-shaped arrangement of the recesses 11.

Fig. 14 shows a variant in which the distribution element 6 'in total upwardly curved in cross-section, that is convex, as well as in the previous figure and contrary to the design in the embodiments previously described in which it was concave. Here there are from one to the other terminal 10 arcuate, ie converging recesses eleventh

Fig. 15 shows a turn flat plate as a distribution element 6 ', in which the recesses 11 also converge again, starting here from the previously explained, directly transverse, wide recess 12 between the connection points 10, the recesses 11 in total but approximately angularly extending and widening at first, towards the end in turn rejuvenating. Interesting here is still a central, wide, to the opposite longitudinal edge of the distribution element 6 'extending additional recess.

Fig. 16 again shows a distribution element 6 'designed in a convex manner in cross-section with recesses 11 which run essentially angularly and otherwise have the same shape as the previous exemplary embodiment.

Fig. 17 shows each one of the respective connection point 10 to the opposite longitudinal edge extending recess 11, which is additionally structured by transverse depressions 11.

Fig. 18 shows a configuration of the depressions 11, which is already explained, in the case of a generally convex cross-sectional shape of the distribution element 6 ', but the distribution element 6' in plan view with an approximately shell-shaped form.

Fig. 19 shows a plan view of a distribution element 6 'with a rather leaf-like shape, here the recesses 11 arranged crossing each other.

Fig. 20 shows an arrangement similar to the previous embodiment, in which, however, the recesses 11 are curved, but also cross.

Fig. 21 shows an embodiment of a distribution element 6 'with a particularly large number of wells 11, which are arranged and executed arcuate and crossing each other.

Fig. 22 shows a distribution element 6 'with straight, but web-like recesses 11 which widen partially or taper and thereby still have a superimposed additional structure.

Fig. 23 also shows a planar distribution element 6 ', in which the similar structure of the recesses 11 is realized by following rows of dots, between which the recesses 11 are located.

Fig. 24 corresponds to Fig. 16 , only with concave rather than convex curvature of the plate.

It has already been pointed out several times above that in the multi-chamber dispensing device according to the invention the dispensing mechanisms known in principle for dispensing devices for a single active substance fluid of the prior art can be used.

After further, independent teaching of the invention, the present patent application but also relates to a dispensing device, which, while taking into account the delivery of several, at least two drug fluids have been optimized, but can also be used as a dispensing device for a single drug fluid.

Fig. 25 shows in this respect a particularly appropriate designed flushing plate, so a fixed distribution element 6 ', which is also carried out again plate-like. In this dispenser two provided in the holder 1 reservoir 2, 3 are provided. But one can also imagine purely constructive as well that this arrangement can be realized even with only one reservoir 2.

It is provided here that the distribution element 6 'on the top in one hand, a starting from a longitudinal edge 13 terminal portion 14 in which a connection point 10 for the outlet opening 4 of the reservoir 2; 3 is arranged, and on the other hand, from the terminal portion 14 substantially to the opposite longitudinal edge 15 reaching Beaufschlagungsbereich 7 'is divided and that the surface in the connection area 14, except for technical reasons, technical connection or sealing reasons existing individual increases, depressions or breakthroughs, running smooth is. It has been found that the smooth upper surface of the distribution element 6 'with the correct setting of the gap between the lower edge of the outlet opening 4 of the reservoir 2; 3 and the top of the distribution element 6 'a sufficient distribution of the active substance fluid and a sufficient loading of the loading area 7' allowed. The experiments realized in the prior art with all imaginable formations in the connection area 14 have thus proved to be not necessarily necessary, if it adjusts other parameters of the overall arrangement appropriate.

This in Fig. 25 illustrated embodiment shows in the connection area 14 is not everywhere a smooth surface, but a smooth surface with the exception of such elevations, depressions or breakthroughs, which are available for technical reasons, technical connection and sealing reasons. It is essential that the surface on which the active substance fluid is distributed, is a smooth surface, so has neither ribs nor grooves, nor is a porous plate.

In the Fig. 25 recognizable circular points serve the attachment of this distribution element 6 'at the holder 1, not shown here.

The illustrated embodiment shows the plate-like distribution element 6 'for both reservoirs 2, 3 together. These are then in the connection area 14 adjacent spaced the connection points 10 for the outlet openings 4 of the reservoir 2, 3. Especially in the mixing of different active fluids, the constructive solution shown here for the distribution element 6 'has proven in practice to be useful.

Fig. 25 further shows that between the outer edge of the connection point 10 and the Beaufschlagungsbereiches 7 'is a wide strip of smooth surface of the terminal portion 14.

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

The exemplary embodiment shown, and thus far preferred, shows the connection points 10, in turn, embodied as a type of impact tip, as has already been described in the exemplary embodiments described above:

The illustrated and preferred embodiment with fixed distribution element 6 ', the in Fig. 25 is now further characterized by the fact that the free flow of the active substance fluid preventing arrangement has a Aufstoßspitze o. The like. At connection point 10 surrounding, here annular surrounding spacer assembly consisting of individual from the surface in the terminal portion 14 slightly upstanding spacers 16th exists, on which the lower edge 17 of the connection opening 4 of the reservoir 2; 3 gets up. One recognizes in Fig. 25 the circular ring around the Aufstoßspitze at the connection point 10 arranged spacers 16 which are arranged and leave such gaps between them, that the lower edge 17 of the outlet opening 4 of the reservoir 2; 3 can sit there and the active substance fluid between the spacers 16 can escape laterally. At the same time so also entry areas for back into the reservoir 2; 3 flowing air. This is the classical, dynamic interaction of viscous active fluid and air as known in the art ( US 4,995,555 A ; EP 0 785 315 A1 ). The spacers 16 provide here a particularly expedient constructive solution of the total required for the function of the dispenser exchange.

An alternative is, moreover, that, like Fig. 27 shows, the lower edge 17, the outlet opening 4 of the reservoir 2 as a spacer assembly with individual, slightly axially projecting spacers 16 'is executed, which sit in mounted reservoir 2 on the top of the distribution element 6' in the connection area 14. Since then the spacers 16 'have just moved to the lower edge 17 of the reservoir 2, 3.

This in Fig. 25 shown and preferred embodiment also shows that the Verteifungselement 6 'in the loading region 7' starting from the edge of the terminal portion 14 and approximately to the opposing longitudinal edge 15 reaching recesses 11, which serve to distribute the active substance fluid or the drug fluids in the rinsing liquid. Here are all design options that also already above for such wells 11th have been cited. The illustrated embodiment shows parallel recesses 11. These are known from the prior art for decades.

Fig. 26 shows a vertical section through a dispenser, the distribution element 6 'as in Fig. 25 has shown. It is recognized here that the holder 1 has a storage container 2 or the storage container 2, 3 receiving carrier 18, wherein the Beaufschlagungsbereich 7 'facing front wall 19 at the transition from the terminal portion 14 to the loading area T runs. The front wall 19 of the holder 1 serves to shield the reservoir 2, 3 against unwanted ingress of water. Consequently, it is recommended that the recesses 11 extend below the edge of the front wall 19 in order to form as narrow a gap as possible through which no water can enter. The negative consequences of an unwanted ingress of water into the storage containers 2, 3 have been described in detail above and in the rest the subject of extensive analyzes in the prior art.

Fig. 25 makes the position of the front wall 19 of the holder 1 with respect to the recesses 11 in the loading area 7 'of the distribution element 6' clearly. Fig. 26 Further, it is 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 naturally formed on the holder 18.

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

The illustrated embodiment can in Fig. 26 Incidentally, recognize that the top of the distribution element 6 'in the connection region 14 at the level of the lowest point of the recesses 11 in the loading area 7' extends. The active substance fluid can thus enter the recesses 11 on the face side. At the same time, the accessibility of water under the edge of the front wall 19 is restricted as much as possible. One recognizes in Fig. 26 Moreover, further that between the bottom of the holder 1 and the surface of the distribution element 6 'in the connection region 14 in the free areas results in a considerable vertical distance.

Fig. 25 finally shows that, as already explained, the top of the distribution element 6 'in the connection area 14 for the active substance fluid is smooth, but otherwise may have for attaching technical reasons, connection technology and sealing reasons einzeine increases. Fig. 25 shows as from sealing technical reasons existing increase that in the connection region 14 on the one longitudinal edge 13 facing side of the connection point 10, in particular the spacers 16 comprises on this side, a slightly upwardly projecting from the top protective edge 20 is formed.
