Definitions
- Dispensing device for dispensing an active fluid into the flushing liquid in a toilet bowl
- the invention relates to a dispensing device for dispensing an active substance fluid into the flushing liquid in a toilet bowl with the features of the preamble of claim 1.
- active substance fluid primarily means viscous, in particular also gel-like active substance preparations with a cleaning, disinfecting, deodorising, bleaching, etc. effect.
- present dispensing device is also suitable for active substance preparations which are otherwise flowable, that is to say liquid to viscous (DE 199 30 362 AI, EP 0 775 741 AI, 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, that is to say with a single storage container (EP 0 785 315 AI; DE 199 30 362 AI), are initially known. Also known are dispensing devices for several, in particular two storage containers z. B. for two drug fluids that cannot be stored with one another in a stable manner (DE 201 16 963 Ul).
- the teaching of the present invention can already be used advantageously in dispensing devices for a single active substance fluid.
- the advantages unfold in a particular way in a dispensing device for at least two storage containers provided in a holder, each for one active substance fluid.
- the starting point for the teaching is a delivery device as is known from DE 201 16 963 Ul.
- the surface of the distribution element in the connection area is made smooth, apart from individual elevations, depressions or breakthroughs present for reasons of fastening technology, connection technology or sealing technology.
- a pushing tip or the like on the plate-like distribution element for pushing a plug out of the nozzle of the storage container containing the outlet opening for the purpose of "activating" the dispensing device.
- a guide arrangement preventing free flow of the active substance fluid has a spacer arrangement which surrounds the pusher tip in a ring, on which the socket of the storage container inserted in the holder rests.
- the spacer arrangement consists of individual spacers slightly protruding from the surface of the distribution element in the connection area, on which the ring-shaped connecting piece rests around the connection opening, so that outlet areas for the exit of active substance fluid or entry areas for the entry of air are located between the spacers for pressure equalization.
- the dispensing device can be optimized with regard to the pressure equalization in the storage container and with regard to the — unintentional — entry of rinsing liquid into the storage container. It has been shown that the viscosity of the active substance fluid in the initial state is reduced too much by the entry of rinsing liquid into the storage container, so that undesired emptying of the storage container can be observed.
- the inventive design of the dispensing device results in a kind of meniscus of the active substance fluid in the side outlet opening in the idle state, through which the active substance fluid is constantly present until it is flushed out in a precisely defined portion by the impinging flushing liquid stream. After the rinsing process has been completed, this situation stabilizes again in a defined manner.
- the amount to be dispensed can be predetermined by the width and height of the outlet opening, the formation of the meniscus also being influenced by the depth of the boundary surface of the outlet opening.
- the local separation of the supply of the rinsing liquid on the one hand and the delivery of the active substance fluid on the other hand results in a long-lasting continuous delivery of the active substance fluid into the rinsing liquid with each rinsing process.

- FIG. 8 b shows a half section through the distribution element according to FIG. 4 b in an end view after the opening process has ended
- the dispensing device specifically shown in the drawing serves to dispense two active fluids into the flushing liquid, that is to say in particular the flushing water, with which flushing is carried out in a toilet bowl.
- two guide arrangements are provided on the distribution element of the dispensing device for fitting corresponding storage containers.
- active substance fluid in the sense of the teaching has been defined in the general part of the description. The teaching is not limited to the use of two active fluids. It is already relevant when using a storage container with an active fluid. It is also relevant if the number of storage containers is increased.
- Fig. 1 shows, for a basic explanation of the construction and function of a dispensing device of the type in question, an illustration which is taken from the prior art. This figure can be understood in conjunction with FIG. 2 and in particular FIG. 5 of the drawing with reference to the dispensing device specifically described here, because the position of the container neck with the outlet opening of the storage container is indicated in FIG. 5 in broken lines.
- the dispensing device shown in the drawing for dispensing an active substance fluid into the flushing liquid in a toilet bowl initially has a holder 1 which can be suspended from the edge of a toilet bowl and at least one storage container 2 for an active substance fluid provided in the holder 1.
- An arrangement is particularly preferred in which two storage containers 2 are provided in the holder 1, which, more preferably, are separated from one another and each contain an active substance fluid.
- the storage containers are separated from one another in order to prevent premature mixing of the active substance fluids. They can be designed physically separately or as separate compartments in a coherent body.
- Active substance fluids suitable according to the invention are, for example, fragrance phases, in particular perfumed fragrance phases.
- 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, other surfactants or emulsifiers, stabilizers, limescale dissolver etc.
- Bleaching phases in particular chlorine-containing bleaching phases, preferably bleaching phases based on hypochlorite, are likewise suitable according to the invention as active substance fluids, the bleaching phases usually being able to contain, besides the actual bleaching agent and water, possibly further ingredients such as thickeners, surfactants or emulsifiers, neutralizing agents, dyes, fragrances, etc.
- active substance fluids of this type it is preferred, for reasons of sealing, to use the one-piece closure variant shown in FIG. 7 with a film-like stopper. Experiments have shown that the closures normally used, as shown in FIG. 1, are not leakproof when chlorine-containing active substance fluids are stored.
- 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.
- active substance fluids with an 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.
- further ingredients such as, for example, surfactants or emulsifiers, thickeners, fragrances , Preservatives, etc.
- the active substance fluids are enzyme-containing active substance phases.
- enzyme-containing active substance phases can optionally contain further ingredients such as surfactants or emulsifiers, thickeners, fragrances, preservatives, etc.
- the active substance fluids used according to the invention are absorbent, in particular odor-absorbing active substance phases.
- these can optionally contain further ingredients such as surfactants or emulsifiers, thickeners, fragrances, preservatives, etc.
- the dispensing device offers the possibility of using combinations of different active substance fluids in the storage containers, wherein according to a preferred embodiment one of the storage containers contains a fragrance phase, in particular as previously defined.
- active ingredient-fluid combinations to be used are perfumed fragrance phase combined with chlorine bleach (together not stable in storage), veneered 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.
- the storage container 2 has a container nozzle 3, in which there is an outlet opening 5 which is closed by a plug 4 when the storage container 2 is closed.
- the plug 4 can be seen in Fig. 1 in the active fluid in the reservoir 2 floating because it has been pushed out of the outlet opening 5 there.
- the active substance fluid can be dispensed into the rinsing liquid via the opened outlet opening 5, that is to say when the storage container 2 is “activated”.
- Gravity, negative pressure above the liquid level of the active substance fluid in the storage container 2, dilution of the active substance fluid at the dispensing point etc. are just as important for the dispensing of the active substance fluid from the storage container 2, as is the spatial position of the dispensing device in the toilet bowl, the intensity of the flow of the flushing liquid, etc.
- the sealing of the storage container 2 in the holder 1 takes place over the surface between a container nozzle 3 and the nozzle 8 of the guide arrangement.
- the closure cap 22 of the storage container 2 shown in FIG. 7 can be used as an alternative to the two-part closure system shown in FIG. 1, consisting of a closure cap 22 with an inserted plug 4, the closure cap 22 of the storage container 2 shown in FIG. 7 can be used.
- the cap and plug 4 are made in one piece.
- the plug 4 is articulated by a film-like hinge 21 with the closure cap 22 after insertion.
- the film-like plug 4 is cut by the cutting edges 20.
- the film-like plug is cut out completely and floats in the active fluid.
- Means for generating buoyancy in the float are advantageously provided
- the blades 20 required for such an opening mechanism can preferably be designed in terms of type and number such that, as shown in FIGS. 8 a and 8 b, the plug 4 does not completely protrude from the closure cap 22 triggers, but a remaining remainder of the film forms a hinge 21.
- the nozzle 8 projects through the outlet opening 5 into the interior, so that the plug 4 is secured against closing.
- the type and number of the cutting edges can preferably also be designed such that when the storage container is pressed into the holder, the film-like articulation is completely separated by the cutting edges, and the plug cut out as a result floats upward due to the difference in density to the liquid in the storage container.
- a distribution element 6 is provided on the holder 1 under the outlet opening 5.
- the interior of the storage container 2 is continuously connected to the distribution element 6 via the outlet opening 5 with the interposition of a guide arrangement 7 preventing free flow of the active substance fluid, so that active substance fluid is always present on the distribution element 6 in the region below the outlet opening 5 of the storage container 2.
- the distribution element 6 is arranged in the holder 1 in such a way that the active fluid on the distribution element 6 is diluted by the washing liquid during each rinsing process and is washed away by the distribution element 6.
- the guide arrangement 7 has an upwardly projecting connector 8, which seals into the container neck 3 of the storage container 2 and forms the outlet opening 5.
- the nozzle 8 has an internal channel 9, which is open downwards to the distribution element 6.
- the construction of the dispensing device in the area of the distribution element 6 is fundamentally different in the dispensing device according to the invention than in the Dispensing device of the prior art, which has been shown in FIG. 1 for a basic explanation and has been described above.
- FIGS. 2, 3, 4 and 5 show the position of the storage container 2 with the container nozzle 3 relative to the guide arrangement 7 on the distribution element 6.
- the connector 8 of the guide arrangement 7 on the side facing the flushing liquid encountered when the dispensing device is suspended in the toilet bowl that is the side on the bottom in FIG. 2, the side on the top in FIG. 3 and the right-hand side in Fig. 5, is connected over part of its circumference to the distribution element 6, so that a shield for a between the distribution element 6 and the lower edge 10 of the nozzle 8 otherwise formed side outlet opening 11 for the active fluid is formed.
- the dimensions of the lateral outlet opening 11 are chosen taking into account the product properties, in particular the viscosity of the active substance fluid, so that the active substance fluid is present in the lateral outlet opening 11 in the idle state, that is to say without any significant effect of rinsing liquid.
- “Pending” here means that the active substance fluid does not flow continuously in the idle state, but that a kind of “miniscus” of the active substance fluid forms under its own surface tension in or on the side outlet opening 11, which prevents undifferentiated flow of the active substance fluid.
- the side outlet opening 11 can be seen particularly well in FIG. 5.
- the fastening pins 12 for fastening the distribution element 6 to the holder 1 are also shown here. Their position can be seen particularly well in FIGS. 2 and 3.
- the fastening pins 12 are of no importance for the functioning of the dispensing device according to the invention.
- the lower edge 10 of the connector 8 For the formation of the mirror of the active substance fluid in the lateral outlet opening 11, it can be expedient to widen the lower edge 10 of the connector 8 compared to the natural width resulting from the wall thickness of the connector 8. This can be provided, and this is also done in the present exemplary embodiment, in such a way that the lower edge 10 of the connecting piece 8 is designed as a wide, laterally projecting flange which, together with the corresponding section of the distribution element 6, forms a meniscus of the active substance fluid in the lateral outlet opening 11 facilitated. This can be seen particularly well in FIG. 4 and in FIG. 5.
- the lateral adhesion of the active substance fluid to the flange and the corresponding surface of the distribution element 6 stabilizes the outlet of active substance fluid at the lateral outlet opening 11 and leads to defined relationships with the active substance fluid at a standstill the rinsing processes.
- the connector 8 has an inner diameter of approximately 5 mm.
- FIG. 6 shows a "top view" of the nozzle 8 of the guide arrangement 7, from which the special conditions in the nozzle 8 can be clearly seen in a preferred embodiment.
- a flow-restricting arrangement 13 is provided in the nozzle 8, by means of which, preferably, the flow is restricted to a crescent-shaped flow cross-section.
- the restricted, preferably crescent-shaped flow cross-section has a maximum width b of approximately 1.5 mm to approximately 2.5 mm.
- the arrangement of the arrangement 13 restricting the flow in the channel 9 of the connector 8 determines the flow conditions here.
- This Arrangement 13 can thus, depending on the active ingredient fluids to be used and their viscosity, the surface tension to be expected and the pressure to be expected at this point, provide a precisely defined, desired characteristic for the flow rate with different filling states of the storage container 2.
- the illustrated and preferred exemplary embodiment of the typical active substance fluids that are to be used here can be specifically designed in such a way that the clear height of the lateral outlet opening 11 is approximately 1.5 mm to approximately 3.5 mm, preferably approximately 2 mm. 5 mm, and / or the lower width of the lower edge 10 of the nozzle 8 is approximately 1.5 mm to approximately 3.5 mm, preferably approximately 2.5 mm.
- the dispensing device has been described as if the guide arrangement 7 for the respective storage container 2 were readily located on the distribution element 6. In principle, this is also a functioning construction. In this case, however, the lateral outlet opening 11 is relatively strongly exposed to the rinse water access during the rinsing process.
- the distribution element in FIG. 2 faces the viewer and, when the dispensing device is suspended in the toilet bowl, faces the impinging flushing liquid, which has an area 14 over which flushing liquid flows during the flushing process.
- the rinsing liquid also flows from the application area 14 to the rear edge of the distribution element 6 in FIG. 2. This is otherwise provided here jointly for both storage containers 2 of the specific embodiment.
- the two guide arrangements 7 for the two storage containers 2 are stronger with regard to the exposure to washing liquid. shielded. It is namely provided that the guide arrangement 7 is at least on the side facing the impinging flushing liquid when the dispenser is suspended in the toilet bowl, and proceeding from both sides of the guide arrangement 7, is surrounded by a baffle wall 15 projecting from the distribution element 6. Within the baffle 15, because it extends at a distance from the nozzle 8 of the guide arrangement 7, there is a trough-like receptacle for flushing liquid which is open at one end and whose filling level depends on the inclination of the distribution element 6 in the toilet bowl. One can well imagine this from the illustration in FIG. 2.
- the upper edge of the baffle wall 15, at least on the side facing the flushing liquid which is in the dispensing device suspended in the toilet bowl, is higher than the lower edge 10 of the nozzle 8 in the region of the outlet opening 11. is particularly well known in Fig. 5 of the drawings.
- the height of the baffle 15 naturally plays an important role in the formation of the tub effect which has been mentioned previously.
- the upper edge of the baffle 15 relative to the upper side of the distribution element 6 is at a height of approximately 3 mm to approximately 7 mm, preferably from about 5 mm to about 6 mm.
- a barrier is created which prevents the lateral outlet opening 11 of the guide arrangement 7, in which the active substance fluid is present, against an immediate shields the direct impact of the flow of the rinsing liquid.
- the channel 9 in the connector 8 of the guide arrangement 7 serves for the jerk ventilation of the storage container 2. Because of the special design, a Avoid swamp formation.
- the drawings further show in connection that a defined position of the storage container 2 with respect to the distribution element 6 in the exemplary embodiment shown is realized in that on the connection piece 8, preferably only on the side acting as a shield, a support 16 for the container connection piece 3 forming the outlet opening 5 of the storage container 2 is arranged.
- This has a height that is greater than the height of the baffle 15, so that a gap-like overflow for rinsing liquid is formed.
- the height here is between approximately 6 mm and approximately 8 mm from the surface of the distribution element 6.
- the application area 14 of the distribution element 6 essentially only has in the dispensing device shown due to the local separation of the dispensing of the active substance fluid from the supply of the rinsing liquid the task of holding rinsing liquid with active substance fluid for a while after the completion of a rinsing process in order to bring about a long-lasting release of fragrance.
- the rib structure of the application area 14, which can be seen in FIG. 3, increases the surface and increases the related scent after-effect between the rinsing processes.
- the drawing shows a closed baffle 15.
- one or more, preferably slit-like openings 17 could also be provided in the baffle 15 in order to slowly flush the rinsing liquid which is present within the baffle 15 with a high proportion of active fluid onto the area of application 14 between flushing processes Let leakage element 6 out.
- Such a slot-like opening 17 can only be seen in FIG. 3 on the side of the baffle 15 next to a fastening pin 12.
- the viscosity of the active substance fluid in the initial state be a few thousand mPas, preferably in the range from approximately 2000 mPas to approximately 5000 mPas, in particular in the range from approximately 2500 mPas to approximately 3500 mPas. With these viscosities, the active fluids match the special dimensional specifications described above. For the rest, reference may be made here in particular to the exemplary embodiments of the prior art of DE 201 16 963 U1 mentioned above, which can also be used here expediently.
- Fig. 1 can also provide for the claimed dispensing device that the storage container 2 or the like by means of an adapter 18. coupled with each other and so coupled can be attached in the holder 1. In this way, a refill set consisting of two storage containers 2 can be replaced together.
- an adapter 18 coupled with each other and so coupled can be attached in the holder 1.
- a refill set consisting of two storage containers 2 can be replaced together.
- Fig. 1 indicates that here on the holder 1 on the side facing away from the impinging flushing liquid when the dispensing device is suspended in the toilet bowl, a protective wall 19 shielding the edge of the distribution element is provided.
- This protective wall 19 protrudes downward past the distribution element 6 and shields, at a short distance, the free sides of the baffle walls 15 of the guide arrangements 7, which are particularly clearly recognizable in FIG. 3.
- the protective wall 19 could also be attached to the adapter 18.
- the protective wall 19 could theoretically also be provided on the distribution element 6 itself. The spacing must then be implemented differently, for example by means of webs. In any case, it must be ensured that active substance fluid can be washed away from the rinsing liquid at the edge of the distribution element 6.
- a dispensing device In the exemplary embodiment of a dispensing device according to the invention shown here, air enters the interior of the storage container 2 through the channel 9 in the connector 8, through which the active substance fluid flows out of the storage container 2. Basically, you can also provide a construction with an additional small ventilation opening. Such a dispensing device would then be constructed in such a way that a small air inlet opening is provided on the connection 8 of the guide arrangement 7, preferably in the arrangement 13 restricting the flow in the connection 8, in particular on the upper side thereof. However, the ventilation opening is not shown in the drawing.
- the mode of operation of the dispensing device according to the invention is finally to be explained again in context. A particularly preferred exemplary embodiment is described, the description of which, however, does not limit the disclosure content of the present application as a whole.
- the storage containers 2, coupled in the adapter 18, are inserted into the holder 1.
- the plugs 4 are pushed out or cut in whole or in part, and the container nozzles 3 are placed in a sealing manner on the nozzles 8 of the guide arrangements 7. Sealing is ensured by the automatically forming, flat press fit between the opened closure cap 22 and a preferably conical socket 8.
- the active substance fluids run into the channels 9 of the guide arrangements 7 and form the menisci described, ie concave liquid levels, in the side outlet openings 11 below.
- a negative pressure is created in the two storage containers 2, which, in connection with the surface tension of the active substance fluids, allows a stable state to occur.
- the fragrance delivery from the corresponding active ingredient fluid or from both active ingredient fluids begins.
- the flushing liquid flows from the side in front in FIG. 2, which faces the edge of the toilet bowl, via the loading area 14 of the distribution element 6 onto the baffle walls 15. Due to the turbulent flow, the flushing fluid also flows over the baffle wall 15 get into the gap between the respective baffle 15 and the guide assembly 7. At the same time, small amounts of active substance fluid are also applied to the area of application of the distribution element 6. Active substance fluid located within the baffle 15 is washed away by the partial flow of the rinsing liquid. This portion volume (dosing amount) can be easily metered by dimensioning the outlet opening 11, the distance of the baffle 15 from the guide arrangement 7 and the height of the baffle 15.
- a typical, preferred dosing volume is between 0.05 ml, preferably about 0.1 to 0.5 ml ,
