Definitions

  • the invention relates to a device for dispensing an active ingredient into the flushing water, in particular in toilet bowls, according to the preamble of claim 1.
  • EP 0 53 89 57 B1 describes a device of the type mentioned at the outset and has a container with the container opening facing downward, which contains a liquid-permeable closure in the container opening for the controlled release of the active substance to a porous mass located underneath.
  • the delivery or dosage of the active ingredient can be controlled by the liquid-permeable closure located in the container opening.
  • the porous mass picks up the released active substance and holds it after a rinsing process, which ensures that the active substance is released into the room air.
  • the dosage of the active ingredient in this device is achieved exclusively by the liquid-permeable closure inserted into the container opening.
  • the disadvantage is the provision of a comparatively expensive porous mass combined with the fact that the porous mass itself cannot be used to control or distribute the active substance in the toilet bowl, and consequently the liquid-permeable closure must be provided as an additional element.
  • the invention is based on the object of improving a device of the type mentioned in such a way that the release of the active ingredient by the distributor device can only be controlled with a simple and inexpensive construction of the device itself.
  • the invention provides a device for dispensing an active substance into the flushing water of a toilet bowl and in particular a dispenser in which a liquid active substance which is arranged in a container is dispensed to the flushing water both during the flushing process and on a surface provided for this purpose after the flushing process the distribution device remains and thereby has an odor-improving effect in the area of the toilet bowl.
  • the distributor device provided in the device is essentially defined by grooves crossed to one another.
  • a first group of grooves causes the preferably liquid active substance to be released from the distributor device outwards in the direction of the toilet bowl and a second group of grooves causes the liquid active substance to be distributed within the distributor device.
  • the second group of grooves preferably has a larger open cross-section and effects an adequate distribution of the active substance within the distributor device to the grooves leading to the outside.
  • These grooves or channels are preferably provided in parallel for each group. The grooves of the two groove groups intersect within the distribution device, which ensures a targeted and satisfactory distribution of the active ingredient to the outside.
  • the two groove groups act similarly to capillary tubes, i.e. the liquid active substance is drawn off from the outside via the first groove group either by the flushing water running inside the toilet bowl and via the distributor device or by the automatic evaporation of the liquid active substance outside the individual flushing processes.
  • the cross-section of the individual grooves By appropriately designing the cross-section of the individual grooves, a targeted dosing or a targeted delivery of the liquid active substance into the toilet bowl can be ensured both during and outside the flushing processes.
  • FIG. 2 is a partial sectional view through the device according to the invention, viewed from the side,
  • FIG. 3 shows a plan view of a preferred embodiment of a part of the distributor device
  • Fig. 6 shows another embodiment of the plate-shaped element of the distributor device.
  • the device for dispensing active substances is shown in an exploded view in FIG. 1 and consists of a container 1, preferably of a transparent plastic of any shape, a distributor device 4 composed of two essentially plate-shaped elements 2, 3 and optionally a frame 5 for receiving in particular the distribution device 4.
  • the container 1 is provided with an opening 7 on its side pointing downward in FIG. 1.
  • the opening 7 of the container 1 is closed from the inside by a membrane 8 or the like in order to prevent the liquid active substance of the container 1 from escaping.
  • the membrane 8 or the like is opened by a mandrel 9 or the like.
  • the device according to the invention has a structure consisting essentially of plate-shaped elements 2, 3 as a distribution device for the active ingredient delivery, each element 2, 3 preferably consisting of plastic and being provided in a predetermined manner with grooves, channels or the like.
  • the distributor device consists of a first lower plate 3 and a second upper plate 2 resting thereon.
  • a structure defined by grooves, channels or the like is formed between the two plate-shaped elements 2, 3, which are preferably made of plastic, so that the liquid active substance from the container 1 via the distributor device 4 is opened via these grooves, channels etc. can be dispensed into the toilet bowl or the flushing water.
  • these grooves are formed between the two plate-shaped elements 2, 3, ie the grooves can be on the underside of the element 2, further on the top of the element 3 or on the underside of the element 2 and be formed on the top of the element 3, in the latter case the mutually assigned groove sections communicate with one another, ie run in a congruent arrangement.
  • the first group of grooves or channels is designated 11 and, as shown in FIG. 1, extends transversely to the longitudinal axis of the longitudinal axis of the plate-shaped element 3.
  • the grooves 11 are preferably formed at the same distance from one another as in FIG. 3 emerges and preferably extend over the entire length and width of the element 3, although this is not absolutely necessary.
  • the second group of grooves, which are designated by 12, extends parallel to the longitudinal axis and laterally offset to the central axis, namely along the region covered by the element 2.
  • the number of grooves 12 of the second group is preferably 3, but can be increased and decreased if necessary.
  • the grooves 12 of the second group preferably have a larger open cross section compared to the grooves 11 formed in the transverse direction in order to ensure a full distribution of the liquid active substance over the entire length of the element 3, so that all the grooves 11 running in the transverse direction are sufficiently liquid Active ingredient can be loaded.
  • the element 3 has an essentially rectangular shape.
  • the plate-shaped element 2 provided on the element 3 also has a substantially rectangular shape and, according to FIG. 4, can be provided with additional grooves 12a, which are to be provided in register with the grooves 12 of the element 3, in order to open the cross section of the grooves of the second formed thereby Enlarge group in the area of coverage of elements 2, 3.
  • the upper element 2 is provided with an opening 14, around which a flange-like extension 15 can optionally be formed in order to receive the neck 1 a of the container 1.
  • the element 2 sits on the element 3, the element 2 being provided on the side of the element 3 for the purpose of covering or enclosing the grooves denoted by 12, while the plate-shaped element 3 is on the side extends beyond the plate-shaped element 2.
  • the grooves 11 formed on the remaining free surface of the plate-shaped element 3 serve the liquid active substance, which enters from the container 1 through the opening 7 and through the element 2 through its opening 14 into the connecting channel formed by the grooves 12, via the grooves 11 to be released to the outside, either during the flushing process in the toilet bowl or between flushing processes for the purpose of improving the air.
  • the grooves 11 and 12 are closed, i.e. they form channels or capillary-shaped tubes, while the grooves 11, which are located outside the plate-shaped element 2, are open at the top and can therefore be acted upon by the rinsing water flowing in.
  • the shape of the grooves 11, 12 and 12a can be V-shaped, U-shaped, etc. when viewed in cross-section.
  • the open cross section of the grooves 11 is selected so that the active substance in the container 1 flows out of the distributor device 4 in the direction of the area of the plate-shaped element 3 which is directly accessible to the rinsing water.
  • Figure 4 shows a view of the plate-shaped element 2, viewed from below. It can be seen from FIG. 4 that the underside of the plate-shaped element 2 can optionally also be provided with longitudinally extending grooves 12a, which are in register with the corresponding grooves 12 on the upper side of the lower plate-shaped element 3, as a result of which the open cross section the groove sections 12, 12a combined as a result can be substantially enlarged.
  • the grooves 12 can also be formed only by the grooves 12a on the lower surface of the plate-shaped element 2 and the corresponding grooves 12 on the surface of the plate-shaped element 3 are omitted; in this case, the grooves 12a are then in fluid communication with the grooves 11 running transversely to the element 3, as a result of which the removal of active substance from the container 1 via the distributor device 4 in the direction of the plate section 3a is ensured.
  • the closure device designated 8 e.g. in the form of a membrane or a plug is pressed through the opening mandrel 9 out of the neck-shaped opening 7 of the container into the container.
  • the neck la of the container 1 then sits according to FIG. 2 in the opening flange 15, which can be formed on the plate-shaped element 2 as a circular collar.
  • the portion of the plate-shaped element 3 which extends laterally away from the plate-shaped element 2 is designated 3a in FIG.
  • the plate section 3a is close and approximately perpendicular to the substantially vertical wall of the toilet bowl and is therefore acted upon by the flushing water during each flushing process.
  • FIG. 5 shows an embodiment modified from FIGS. 1 and 2.
  • the same parts as in FIGS. 1 and 2 are provided with the same reference symbols and are therefore not described again.
  • the underside of the invention Device in the first embodiment provided pot-shaped frame or the pot-shaped frame 5 is omitted, which carries a hook-shaped holding device 18 in the embodiment according to FIGS. 1 and 2, which is provided in a known manner in devices of this type for the device on the edge of a toilet bowl or to be able to pinch the like.
  • the holding device 18 is then to be arranged on the distributor device 4 or at another location.
  • only a frame-like substantially flat and square frame 5a is provided, whereby the total height of the device is reduced.
  • the frame 5a only serves to support the plate-shaped element 3 and can even be omitted if necessary.
  • the distributor device 4 is set up in such a way that the grooves 11 are omitted over the region designated by 3a or that the region 3a is produced with a predetermined surface roughness and thus the grooves 11 and 12 exclusively in the region of the overlapping sections of the two elements 2 and 3 are formed.
  • all of the grooves 11 and / or 12 can also be present only on the lower surface of the element 2.
  • the surface roughness of section 3a has the purpose of keeping the liquid active substance emerging on the upper surface of the plate-shaped element 3.
  • the grooves or channels 11, 12 define in the overlapping area between the elements 2 and 3 a tubular connection system, which has the purpose of transferring the liquid active substance that enters the distribution device 4 from the container 1 to evenly distribute the entire length and width of the plate-shaped element 3 in the area of coverage of both elements 2, 3 and, in the embodiment according to FIGS. 1 to 4, additionally to distribute it evenly laterally over the grooves 11 of section 3a to the outside.
  • This communicating tube system approximately has the effect of a capillary system, ie the rinsing water occurring in the area 3a of the plate-shaped element 3 is capable of the liquid active substance from the distribution device 4 to be deducted, this effect being controllable by the choice of the open cross section of the tube or groove system.
  • the cross section of the tube or groove system thus also depends on the consistency of the liquid active substance and therefore allows the life span, ie the delivery time for the active substance, to be controlled depending on the consistency of the liquid active substance.
  • the container 1 can be exchanged after the active substance has been used up, i.e. place a new container 1 by pointing it with the opening 7 facing down, i.e. is placed upside down on the distribution device 4.
  • the container 1 is thus essentially perpendicular to the plate-shaped elements 2, 3.
  • the plate-shaped element 3 is provided on its side facing away from the grooves 12 with a preferably flexible contact section 19, which is shown in FIG. 6 and serves to bring about close contact with the toilet bowl wall, not shown in FIG.
  • the purpose of section 19 is to direct the water running off the wall of the toilet bowl to area 3a in order to improve the mixing of the active ingredient with the flushing water.
  • the section 19 can be of such flexibility that it adapts to the shape of the wall of the toilet bowl and produces a largely tight seal against the wall of the toilet bowl.
  • the entire plate-shaped element 3 according to Figure 6 can have a width as shown in Figure 3 and the grooves 11 can extend to the edge of the section 19, i.e. the grooves 11 can be provided continuously over the sections 19.
  • the distributor device 4 consists of the first and second plate-shaped elements 2, 3, but the two elements on their common edge are preferably no more than one shown film hinge firmly connected and hinged together.
  • one of the two plate-shaped elements 2, 3, for example made of plastic has a flat bearing surface compared to the other plate-shaped element provided with the grooves 11, 12, a certain capillary effect arises compared to the element provided with the grooves due to the preferably central arrangement of the container neck with respect to the distributor device , whereby the dosage of drug delivery is controllable.
  • the active substance is passed outward through the plate-shaped element 3 and into the toilet bowl, the active substance being distributed over the grooves 11 on the surface of the element 2.
  • the water is poured over the open area, i.e. passed over section 3a and washed off the active ingredient.
  • the section labeled 19 is bent upward in the manner of a lip.
  • the grooves 11 have a V-shape and include an angle of 60 ° C., while the grooves 12 in the plate-shaped element 3 run in the longitudinal direction and enclose an angle of 90 ° C.
  • the grooves 12 are distributed over an area of approximately 2/5 of the total area of the element 3.
  • the function of the device according to the invention is based on the interaction between the resulting capillary forces within the grooves 11, 12 on the one hand and the flushing water of the toilet bowl running on the area 3a on the other hand. In this way it is ensured that after activation of the container and after repeated rinsing, leakage and thus consumption of the active substance does not occur, even during subsequent long periods of rest.
  • the lifespan of the inventive Direction extremely increased, in particular the life can be controlled individually by changing the groove structure depending on the active ingredient types used.
  • the subsequent delivery of the active ingredient solution in the container 1 is controlled in a predetermined manner by the capillary forces from the container 1.
