Abstract

The disposal device (1) has a dosing device (5) which is adjustable for the setting of active substance delivered by the flushing process through the disposal opening (7) in the pan. The device has a retainer (3) for fixing it in the pan. A tank (2) is provided for stocking up of a fluid active substance.

Description

The invention relates to a device for dispensing an amount of active ingredient in a toilet bowl during a flushing process. It has a holder for fixing the device in the bowl, a tank for storing a flowable active substance and a discharge opening on the tank for dispensing the active ingredient in the bowl. Such a device is also referred to below as an active ingredient delivery device.

Such scavengers are known in very different embodiments of the prior art. From GB 2 338 495 B, for example, a drug delivery device is known which comprises a housing with a wicking device. The wick device serves to direct an active ingredient from a reservoir into an area within a flush water flow in the toilet bowl. In addition, means are provided by means of which the housing can be hung on the edge of a toilet bowl, the apparatus being constructed so that the wick means can be adapted to different positions relative to the housing to accommodate toilet bowls of different shapes and different To be able to cooperate flushing systems reliably.

Another such device is described in EP 1 046 756 A1. It comprises a holder which can be attached to the edge of a toilet bowl in an area which can be acted upon by rinsing water. On the holder, a container for liquid active ingredient is arranged such that an outlet opening of the container is directed downwards and has a distance from an inner basin bottom of the holder. The outlet port is closed with a plug having calibrated holes for delivery of the drug in a controlled amount. The holder is also designed so that rinse water can collect on the inner pelvic floor up to a certain height. The water level thus has a predetermined distance from the stopper. Thus, a reservoir is created over the inner pelvic floor, in which after each rinse a defined amount of water remains, which mixes with a defined by means of calibrated holes amount of active compound to a drug solution, which is rinsed in the subsequent rinse in the toilet bowl.

Another such drug delivery device discloses WO 01/31128 A1. Again, a drug container with a downward opening of a holder on a Edge of a toilet sink held. The opening of the active substance container comprises a plurality of outlet openings, which can be closed with pin-shaped elements. The cone-shaped elements protrude from a concave-shaped oscillating plate, which pushes the peg-shaped elements into the outlet openings so far in an idle state that they are reliably closed. In addition, in a resting state of the vibrating plate, a space remains between the opening of the drug container and the concave-shaped vibrating plate. By Spülwasserbeaufschlagung the vibrating plate can be deflected defined, so that it releases the openings in an operating state on the one hand, whereby a defined amount of the active ingredient can escape from the tank. On the other hand, rinsing water and active ingredient can be mixed on their concave surface to form a solution of active substance, which is subsequently rinsed into the rinsing basin.

The invention has for its object to provide a drug delivery device that can be adapted even more to different conditions of use.

To solve this problem, a device of the type mentioned is proposed, which has a metering device which is adjustable with respect to the discharged through the discharge opening in the bowl amount of active ingredient. The metering device according to the invention is not necessarily arranged on or in the discharge opening itself, but can also act only on them. This is an active ingredient dispensing device - hereinafter also referred to as "toilet scent" called - created, which is the respective use frequency customizable. So it is z. B. makes sense for a little-frequented visitor's bathroom of a family house to set the amount of active substance delivered in a rinse relatively high, so that in particular the fragrance effect persists as long as possible. On the other hand, a company's frequently used employee toilet may reduce the amount of drug delivered per wash in the toilet because the time between two uses that must be olfactory-bridged is shorter and unwanted odors are less likely in the shorter amount of time can fix.

The metering device can be designed in different ways, provided that it allows the adjustment of an amount of active substance which can be adapted to the respective circumstances and which the WC liquid scent blower makes available per flush cycle. In an advantageous embodiment, the invention has a version in which the tank can be received in an operating position. It also comprises a support which can be placed in one of at least two positions in the Version is used and are arranged on the different metering, each leading to a different limit of the delivered per rinse drug amount. The use of different metering elements, which can be selectively activated, makes the operation of the metering device of the WC liquid scent cleaner understandable and comprehensible to the user. Their ease of understanding, in turn, facilitates the operation of the metering device for the user.

In principle, therefore, the carrier can be designed in any geometric shape that can be accommodated in the version in different positions and can be arranged on or on the dosing. For example, it may be cubically shaped and rotatable about an axis orthogonal to two opposing surfaces. Dosing elements can then be arranged on the remaining four surfaces. In an advantageous embodiment of the invention, the carrier comprises a turning plate, thus has a substantially planar shape. On its surfaces lying opposite one another, the insert can have the various metering elements, so that in a first operating position a first metering element and in a second operating position rotated by 180 ° a second metering element is activated. If more than just two different positions are to be provided for the insert, then the socket can also be designed so that the insert can also be displaced or rotated in order to take further positions and activate further dosing elements, which, however, would increase the production costs. Of course, any combination of the three aforementioned adjustment can be selected. In any case, it is crucial that the carrier or the insert can assume different positions in the socket, in which the dispensing opening is assigned in each case different metering elements. The metering device thus constructed thus represents a compact arrangement which is easy to adjust.

"Adjustable" in this sense means that the user can freely select the desired setting of the metering device, ie activation of the respective metering element, set and in some embodiments of the invention can also subsequently change. A subsequent change in the setting of the metering device, in particular, when the device is already in the toilet bowl in use, but is rarely required because it would require the proverbial handle to the loo, which, however, is generally largely avoided. A further advantageous embodiment of the invention therefore has a version in which the insert is permanently latched. Once the user has set the metering device, the dosage is fixed unchangeable. It can therefore no longer be adjusted by other external influences, for example by the careless use of a toilet brush.

The device should be designed to reliably deliver the amount of active agent metered to each rinse to the rinse water. According to an advantageous embodiment of the invention, downstream of the discharge opening as a dosing a buffer tank or a buffer space for temporary storage of that amount of active ingredient is arranged, which is exposed to each rinse the rinse water. The buffer tank thus defines exactly the subset of the tank contents that is available for each rinse cycle. The buffer tank is advantageously designed so that it is the rinse water even at slightly different flow conditions, eg. B. as a result of changing water pressure, is purged freely. It should also be ensured that the inflow of active substance from the tank into the buffer tank is stopped when it is filled to a certain height. This is usually done by the appropriate construction of the tank and the buffer pool and their relative position to each other. Criteria for this are, on the one hand, the distance between the discharge opening and a bottom surface of the buffer tank, the pressure equalization in the tank when the active substance flows out, and the surface tension of the flowable active ingredient.

According to a further advantageous embodiment of the invention, the metering device comprises at least two buffer tanks of different sizes, which can be selectively activated. Thus, a metering device is created whose setting is easy for the user to see through the size of the respective buffer pool and understand.

The formation of the buffer tank on or on the carrier can be done in many ways. Without restricting the invention, the starting point is a turning plate on which the buffer basins are formed, even if the buffer basins can, in principle, also be arranged on a different type of support. According to an advantageous embodiment of the invention, the buffer tanks are formed on the insert itself by the insert forms a bottom of the buffer tank, rise from the walls as lateral boundaries of the buffer pool. Due to the dual function of the insert as a support on the one hand and as the bottom of a buffer tank on the other hand, both a material saving and a compact design can be achieved. According to this principle can Also, the bottom surfaces of two buffer pools, which are respectively arranged on opposite sides of the insert, coincide. Of course, this principle can also be applied to other embodiments of the inserts - for example displaceable or rotatable. The decisive factor is that as many components as possible have a dual function in order to utilize the advantages of the compact design and material savings. Subordinate to this goal or independent of it, the floor plan of the buffer basins can be selected either round or square or combinations thereof.

One or more buffer basins can in principle occupy the entire surface of the insert. According to a further advantageous embodiment, however, a buffer pool occupies only a part of the insert and leaves an edge free to leave room for further functional elements.

As indicated above, the insert can take on a variety of geometric shapes. According to an advantageous embodiment of the invention, the insert is bent and / or curved. In an arrangement of the buffer pool in the bending region or on the concave surface of the curved plate, the walls of the buffer pool can thereby be lower, which in turn means a saving of material. By a bend or a curvature of the plate also an inclination of the buffer pool against a direction of insertion of the insert in the socket can be achieved. It may be required in a tilted operating position of the device in a generally concave-shaped toilet bowl to achieve horizontal alignment of the edges of the active buffer pool, thereby preventing undesirable overflow of active ingredient across the pool edge.

Of course, rinse water is also found in the buffer tank after each rinse. It can lead to the fact that new active ingredient from the tank, which is added to the buffer tank, mixes with the rinsing water, is diluted and thus the dosage is falsified. According to an advantageous embodiment of the invention, therefore, a wall of the insert is slotted. With a slot width of about 0.4 mm to 0.6 mm, for example, it can be ensured via the higher surface tension of the active ingredient that only water and no active substance can pass through the slot. In this way, a drainage possibility for the rinse water is given, whereas the active ingredient is retained in the buffer tank as intended. Advantageously, the slot is at the lowest point of the buffer pool - So in the area of the bend or the curvature of the insert - mounted so that the rinse water can flow as completely as possible. The active ingredient concentration or dosage of this embodiment is therefore not affected by the rinse water.

However, it is not completely ruled out that residual water in the buffer pool still mixed with active ingredient and then flows as an active substance-water mixture through the slot. According to an advantageous embodiment of the invention, upstands are therefore formed on the edges of the insert in the region of the bend or the curvature. Together with the wall of the buffer basin, they form a sump in which the outflowing mixture is collected. Because, especially with dyed active ingredient, it would otherwise cause colored dripping noses of the active substance-water mixture to leak out of the liquid scent and drip into the toilet bowl. This could misinterpret the user as an indication of a malfunction of the device, which is therefore to be avoided as far as possible.

Design and construction of the device are to be chosen so that they are easily transparent to the operator and easy to assemble. An advantageous embodiment of the invention therefore has at one edge of the insert a grip element for operating the insert. In addition to the simple operation of the insert can be helped by the design of the handle member also that the operator immediately recognizes the handle element as such, which in turn facilitates the operation of the device.

In principle, a metering device can also be achieved by any other construction which acts on a flow of active substance through the delivery opening. According to an advantageous embodiment of the invention, the metering device therefore comprises adjusting means for adjusting the discharge opening. As "adjusting" in the context of this invention, all devices are to be considered, which determine the opening width of the discharge opening and consequently their flow and change and which are permanently fixed in a set or an altered position. A simple embodiment for adjusting means may comprise two bodies, which lie directly against each other at one of their boundary surfaces. They have through holes that can be made to coincide with each other. The opening width of the discharge opening can now be changed by the fact that the two bodies are displaced or rotated relative to one another in such a way that their passage openings are only partially or not at all covered. In the last case would be closed the discharge opening. This last-described metering device can be used as an alternative to one of the embodiments described first. However, a maximum of adjustment possibilities can be achieved if the metering device described last is combined with a carrier or with metering elements, in particular buffer tanks, according to one of the embodiments described first.

The adjusting means can be designed almost arbitrarily. They are particularly advantageous disk-shaped. In a preferred embodiment of the invention, the flow through the discharge opening is therefore changeable by means of a control disk as adjusting means. The control disk can be fastened in the metering device in various positions in which it covers the discharge opening completely, partially or not at all. Preferably, the discharge opening is arranged asymmetrically in the metering device. In addition, the control disk has an outline shape corresponding to the metering device, by means of which different positions of the control disk in the metering device and relative to the discharge opening can be defined, for example, by latching into the metering device. In the case of a square shape of the metering device and a triangular shape of the control disk, for example, four different positions can result, in principle, in which the control disk can be inserted into the metering device relative to the discharge opening. If only two positions of a triangular control disk are to be selected, this can advantageously be achieved by a rectangular or diamond-shaped outline shape of the discharge opening. The user can use the control disc of choice so that there is a total desired opening width of the discharge opening.

The adjustment means are also advantageous to construct so that they are easy to use. In a further advantageous embodiment of the invention, the control disk is therefore rotatably arranged in the metering device. The metering device of such an arrangement is advantageously round. Different positions may then be defined by, for example, detents, for example, by engaging one or more detents on the control disk with grooves in the metering device. In this construction, the control disc already factory takes their intended position for dispensing opening, without the user would have to use them first. Besides, she is so captive.

According to a further advantageous embodiment of the invention, a handle is arranged on the control disk for their operation. It facilitates the insertion or the twisting of the Control disc in the metering device. In the case of a rotatable control disk, the handle is preferably arranged to extend radially. He can also define a distance between the discharge opening and the bottom of a buffer tank with appropriate dimensioning.

WC liquid scents are a mass-produced high volume product. Therefore, the drug delivery device is as easy to use and to make economical in their production in the material consumption. An advantageous embodiment of the invention is therefore characterized in that the holder is integrally formed with the tank. The tank as a drug container represents the heaviest component of the device and therefore must be formed most stable anyway. Therefore, there is no significant additional cost of materials, if the holder is preferably integrated in an outer wall of the tank or connected to an outer wall.

In a separate embodiment of the holder is to make sure that it allows the most possible investment of the tank at the edge of the bowl. Therefore, an advantageous embodiment of the invention provides that the holder is inserted into a recess in the tank and clamped firmly in the operating position of the tank in the recess. For this purpose, the holder is advantageously conically shaped and can be inserted into a conical or dovetail-shaped depression in the tank. The taper of holder and recess allows a structurally simple adhesion and thus a very simple power transmission of the weight of the tank on the holder.

Views of two inserts for use in a device according to FIG. 14.

A first embodiment of the invention is shown in Figures 1a and 1b in two perspective views. The device 1 comprises a tank 2 for storing a flowable active substance, a holder 3 for fixing the device 1 in a toilet bowl, a socket 4, to which the holder 3 is attached and which receives the tank 2, and a turning plate 5, which in the version 4 is inserted and to their operation opposite gripping elements 6, 6 'has.

The tank 2 has a discharge opening 7, which can be seen more clearly in FIG. The version 4 is composed of a slotted front panel 8 and side legs 9 together. About bracket 10, the holder 3 is connected to the socket 4. On an underside facing away from the tank 2, the socket 4 also has an apron 11.

The tank 2 is brought in the version 4 in an operative position by being inserted with the discharge opening 7 ahead from above into the socket 4. Its required for operation end position is defined except by the bracket 10, which cooperate with recesses 12 on the tank 2, by a conical recess 13 on the same side of the tank 2, which corresponds to a correspondingly shaped shaft 14 of the holder 3. For mounting the tank 2 in the socket 4, the shaft 14 of the holder 3 is inserted into the conical recess 13 of the tank 2 until it sits in a working position of the tank 2 in fit.

When inserting the tank 2 in the socket 4, the discharge opening 7 is pushed onto a hollow mandrel 15 on the insert 5. This has the consequence that a (not shown) closure of the discharge opening 7 is pierced and the discharge opening is released. Thus, the active ingredient contained in the tank 2 can enter through the discharge opening 7 and the hollow mandrel 15 in a laterally in connection with Figure 5 explained in more detail, arranged on the insert plate 5 buffer pool.

On the insert 5, two buffer basins 16, 16 'are arranged as a buffer space for the active ingredient, to each of which a hollow mandrel 15, 15' is assigned, as shown in Figures 3 and 5. An operator may, as required, activate a buffer tank 16, 16 'of his choice by inserting the insert 5 into the socket 4 in the appropriate position. For a defined recording and permanent locking of the insert 5 in the version. 4 has the version 4 on the inner sides of its side legs 9, an inclined guide rib 17, a horizontal stop 18 and a detent 19.

The interaction of these design features with an edge 20 on the insert 5 represent the figures 4a and 4b. The edge 20 of the insert 5 is inserted between the catch 19 and the rib 17 and following the inclination of the rib 17 in the direction of the front panel 8 of Retainer 4 pushed in the direction of arrow A until it rests on the stop 18 and thus abuts the front panel 8. Subsequently, the turning plate 5 is pressed in the direction of the arrow B down so that a latching nose of the catch 19 engages around the edge 20 around. Now, the edge 20 and with it the insert 5 extends in the horizontal direction, as Figure 4b shows. In this position, the downwardly directed hollow mandrel 15 'is hidden behind the skirt 11 on the underside of the holder 4, so that it is not visible in the front view of the device 1 according to FIG. 1a. Depending on the design of the catch 19 can be ensured that the user for changing the setting, the insert 5 can be removed again from the socket 4 and plug in another position again, or that always before starting the device selected by the user a one-time setting can be and then the insert is not releasably locked in the socket 4.

FIGS. 5a and 5b show a perspective view of the reversing plate 5, wherein FIG. 5a shows an upper side of the reversible plate 5 and FIG. 5b shows an underside of the same reversible plate 5. The reversible plate 5 comprises on its upper side a planar section 21, which faces the handle element 6 at an angle. This results between the planar portion 21 and the handle member 6, a kink 22. From the planar portion 21 of the insert 5 climb two lateral walls 23 and a front wall 24 and form together with the handle element 6 the buffer tank 16. A mirror image buffer tank 16 ' is formed on the opposite side of the insert 5 by the walls 22 ', 23' and the handle member 6 '. However, the buffer tank 16 'is narrower and thus provides a smaller volume. From the bottom of both buffer spaces 16, 16 'formed by the planar section 21 of the insert 5, the hollow mandrels 15, 15' rise. Its layout is circular, and its lateral surface is interrupted radially by slots 26, 26 '. On its outer side and on the bottom of the buffer spaces 16, 16 'spacers 25, 25' are arranged. Now, the tank 2 is inserted into the socket 4, in which a turntable 5 used in the manner described above Thus, the hollow mandrel 15 pierces a closure of the discharge opening 7. Thus, drug can penetrate from the tank 2 through the slotted hollow mandrel 15 in the buffer tank 16. To ensure that when placing the tank 2, the discharge opening 7 is not completely pushed over the hollow mandrels 15, 15 ', so that the slots 26, 26' are completely closed, the spacers 25, 25 'are arranged, which defines a defined opening ensure the hollow mandrels 15, 15 '. The geometry of the discharge opening 7, the hollow mandrels 15, 15 'and the spacers 25, 25' is in coordination with the surface tension of the flowable active substance and the pressure equalization in the tank 2 with outflowing active ingredient coordinated so that the active ingredient flow from the tank 2 in the Buffer tank 16, 16 'comes to a halt as soon as the active buffer tank 16, 16' is filled with the desired defined amount of active ingredient.

The amount of active substance thus defined is available for a rinse for rinsing. After a rinse is still in the rinsed by the rinse water buffer tank 16, 16 ', a residue of rinse water. If he remained in the buffer tank 16, 16 ', he would mix with drug, dilute it and so affect the dosage of the drug. In order to prevent this, the lateral walls 23, 23 'are provided with gaps 27, 27'. The gaps 27, 27 'have only a small opening way of about 0.4 mm to 0.6 mm, so that water can pass through with its lower surface tension, while the active substance has such a high surface tension that it passes through the slots 26, 26 'can not drain. The gaps 27, 27 'are arranged at the lowest point of the buffer tank 16, 16', namely at the bend 22, 22 ', so that complete flushing of the flushing water is possible.

If, nevertheless, a thorough mixing of water and active ingredient should be carried out, which leads to a colored water-active substance mixture, which could escape through the gaps 27, 27 'given a generally selected coloring of the active ingredient, the colored water-active substance mixture would Drain over the planar portion 21 of the insert 5 in the toilet bowl and leave there colored dripping noses. This sight could give the user the false impression of improper functioning of the device 1. In order to prevent this impression, at the edge regions of the grip element 6, 6 'and the planar portion 21 in the region of the bend 22, 22' upstands 28, 28 'are arranged, which between them and the lateral walls 23, 23' of the buffer tank 16, 16 'form a sump for receiving small amounts of water-active ingredient.

FIG. 6 shows an alternative embodiment of a hollow mandrel 15, 15 '. Accordingly, the front side of the hollow mandrel 15, 15' can be formed serrated, wherein a plane on which the tips of the serrations lie is inclined with respect to the planar section 21. This pursues the purpose that a seal of the discharge opening 7 is reliably pierced.

An alternative embodiment of a buffer pool represents the capillaries 30 shown in FIGS. 7a and 7b. They run as narrow channels in the plane of a turning plate 31 and are fed from a hollow mandrel 32. Thus, a defined amount of active substance is also provided by them , which is rinsed in a rinse by overflowing water. On the insert 31 different arrangements of capillaries 30 are formed on the opposite sides, which in turn expose the rinse water different amounts of active ingredient per rinse cycle.

FIG. 8 shows the device 1 in an operating position. It is attached by means of the holder 3 at the edge 33 of a toilet bowl 34. Due to the installation of the device 1 on an inclined inner edge 35 of the toilet bowl 34, the device 1 also receives an inclination. In order to avoid leakage of the buffer basins 16, 16 'at this inclination, the upper edges of the lateral walls 23, 23' are also inclined (see Figures 5, 6, 9 and 10), so that the edges assigned to the upper buffer basin 16 run horizontally in the operating position shown in Figure 8.

FIGS. 9a and 9b show a fourth embodiment of a turning plate 60. The insert 60 differs from the previous insert 5 by a different design of the handle members 61, 61 '. Accordingly, the handle member 61 extends in a direction from a first edge 62 to a second edge 63 of the insert 60 only to about the middle thereof, that is about half as wide as the entire insert 60. In addition, they are with respect to a planar portion 64th the insert 60 no further handle element directly opposite. In a manner similar to the gripping element 61, the gripping element 61 'is arranged, but with respect to the planar section 64 of the turning plate 60 on the side opposite the gripping element 61. It therefore runs from a second edge 63 in the direction of the first edge 62 of the insert 60 only to the middle. A web wall 65, which runs at right angles to the planar section 64 of the insert 60, connects the two gripping elements 61, 61 'with one another and gives them additional stability. This design of the grip elements 61, 61 'offers advantages in production, since only a two-part mold is required for production in an injection molding process, and is therefore cheaper.

The design of the grip elements 61, 61 'also has the consequence that although the lateral wall 66, which tapers on the handle member 61, can remain unchanged, but the opposite side wall 67 of the buffer tank 68 takes a cranked course. In the region of the planar section 64 of the turning plate 60, the lateral wall 67 runs parallel to the lateral wall 66. In the region of the bend 69, it bends at right angles toward the wall 66 and follows the bend 69 approximately to the middle of the turning plate 60. There, in turn, it kinks at right angles, this time, however, in the opposite direction to the first kink, onto the grip element 61. It connects there to the handle member 61 and coincides with the web wall 65. Because of the bent course of the lateral wall 67 in the region of the bend 69, the first gap 70 in the buffer basin 68 is no longer located at the lowest point of the buffer basin 68, namely at the bend 69. He has now moved away in one direction from the handle members 61, 61 '. At the same level, the gap 71 is opposite to it, which however could just as well also be arranged in the region of the bend 69 and thus at the lowest point of the buffer basin 69.

Figures 10a, 10b and 10c offer different views of a fifth embodiment of a turning plate. The reversible plate 80 has a structure that is comparable in principle to the reversible plate 60. It also has gripping elements 81, 81 'which in each case do not extend over the entire width of the reversing plate 80. In contrast to the insert 60, however, the lateral wall 82 of the insert 80 in the region of the handle member 81 is not rectilinear, but kinks in the region of the bend 83 of the insert 80 at an angle greater than 90 ° from the previous direction outwardly away from the buffer tank 84 away , In order for a funnel-shaped water inlet is formed in the buffer tank 84, which favors the inflow of the rinse water into the buffer tank 84.

It can also clearly be seen in FIG. 10c that the hollow mandrel 85 has only one slot 86 through which active substance can enter the buffer basin 84 from the tank 2. So when putting the z. B. shown in Figure 2 tanks 2 which also recognizable there discharge opening 7 maintains a distance from the bottom of the buffer tank 84 are - as already described in Figure 5 - spacers 87 are arranged. They keep an opening free from the Slot 86 and the distance between the bottom surface of the buffer tank 84 and the discharge port 7 is formed. About them, the drug can escape from the tank 2. In addition, a pressure equalization must occur by the entry of air into the tank 2 instead of the leaked agent. In the case of two opposing openings of this kind and the tilted position of the toilet scent in the toilet bowl shown in FIG. 8, one of the two openings may-in absolute terms-be higher than the other. The higher opening thus determines the degree of filling of the buffer tank 84, because an additional flow of active substance from the tank 2 into the buffer tank 84 is stopped only when the active ingredient level in the buffer tank 84 has reached the upper of the two openings. Thus, a subsequent flow of air is hindered as compensation for the outflow of active substance from the tank 2, whereby a further outflow of active substance from the tank 2 is prevented. As a result of the arrangement of only one slot 86 or the arrangement of the gaps 26, 26 'shown in FIG. 6, the liquid level of the active substance in the buffer basin 84 can consequently be set lower and thus an economical consumption of active ingredient can be achieved.

The gap 86 is also arranged so that it is not directly applied by inflowing rinse water flowing through the handle member 81 in the buffer tank 84, directly. This has the consequence that the filled with active substance interior 88 of the Hohldrns 85 can not be rinsed out prematurely or even rinse water penetrate through the hollow mandrel 85 into the tank 2 and there can change the drug concentration.

FIGS. 11a and 11b represent a second embodiment of the invention. Accordingly, a device 41 comprises a tank 42 on which a holder 43 is arranged in the manner already described. A partially concealed discharge opening 44 at the bottom of the tank 42 opens into a mesh cup 45. The mesh cup 45 also provides a buffer space and allows through its grid openings that rinse water penetrate into its interior and solve the drug located there and can rinse in a toilet key.

FIG. 12 shows in a partial exploded view of the device 41 the view of a metering device 46 in the discharge opening 44. The metering device 46 is in turn shown in Figure 13 in an exploded view. Accordingly, the metering device 46 comprises two control disks 47 and 48, wherein the control disk 48 in a ring 49 in the immediate System on the control disk 47 and is rotatably mounted relative thereto. For its operation, ie rotation, the control disk 48 has a handle 50 which extends radially over the disk surface of the control disk 48 and rises from this. Both control discs 47 and 48 have openings 51, 52. The opening 51 of the control disk 47 is arranged in the form of a perforation of many individual openings in a first half of the control disk 47, while the second half of the control disk 47 is formed closed. A similar division also has the control disk 48. In contrast to the control disk 47, here the opening 52 is cut segment-like from the disk surface of the disk 48 and comprises approximately a first half of the surface of the control disk 48. It is separated from the second 50 by a second closed surface. The function of the metering device 46 is easy for the operator to see through and operate in this way. It is adjusted in the manner of spice spreaders by the control disk 48 is rotated by means of the handle 50 relative to the control disk 47. The two extreme positions of the metering device 46, so the maximum passage on the one hand and the closure of the metering device on the other hand, are apart by a 180 ° rotation and consist on the one hand in a first position in which the openings 51 and 52 completely come to cover - ie the position according to Figure 13 - and a second position in which the control disk 48 is rotated by 180 °, so that its closed part comes to rest on the opening 51 and its opening 52 is immediately adjacent to the closed area of the control disk 47. This prevents the escape of active ingredient through the discharge opening 44.

A maximum of adjustment of the device 41 can be achieved by the above-described metering device 46 opens onto a turning plate 53 with buffer tank 54, 54 'according to FIG. To accommodate the tank 42 and the insert 53 and to define their position relative to each other again a socket 58 is required. The insert 53 has in principle the same structure as the insert 5 of the first described embodiment, but with the difference that it has no hollow mandrel. It is dispensable because the discharge opening 44 of the device 41 is manually unsealed by the operator. Also, the turning plate 53 has in its buffer tank 54, 54 'spacers 55, 55', which define a distance between the discharge opening 44 and the bottom of the buffer basins 54, 54 'and thus a sufficient opening for the outflow of active substance in the buffer tank 54, 54 'make sure. The function of the spacers 55, 55 'can be taken over by the handle 50 with appropriate training.

FIG. 15 shows two variants of a turning plate 53. The turning plate 53 according to FIG. 15a corresponds to FIG. 14 and is basically constructed in the same way as the turning plate 5 according to FIG. 5. It differs from the turning plate 5 in that it has no hollow mandrel. The turning plate 53 according to FIG. 15b differs from that of FIG. 15a only in that the upper edges of its lateral walls 56 run horizontally with respect to a planar section 57 and do not rise as in FIG. 15a. As already explained in connection with FIG. 8, this means that a device 41 equipped with a turning plate 53 according to FIG. 15b should assume a vertical vertical position in its operating position, while a device 41 using a turning plate 53 according to FIG Figure 15a assumes an inclined position, as shown in FIG.
