Definitions

• the invention relates to a device for dispensing additives to the flushing water in toilet bowls, with a container which holds the additive and can be attached in the bowl and which has at least one passage opening for the additive, which is connected to a capillary-active dispensing aid. which has a layer made of a material having capillary openings.
• a device of this type is already known from EP 0 785 315 A1.
• the known device is a two-part arrangement with a holder which can be attached to the edge of the pool, which holds the position of the capillary-active material in the form of a porous plate and which has holding means via which the container containing the additive can be detachably attached above the porous plate.
• the passage opening is located in an outlet connection of the bottle-like container.
• the outlet connector engages in a connection nipple of the holder and forms, together with the connection nipple, a dropper device which, in conjunction with ventilation openings which are located on the connection nipple next to the through-opening for the additive, forms a metered droplet of the porous plate.
• the known device ensures trouble-free delivery of the additives in the desired amount only if special requirements are met.
• the size of the ventilation openings must be adapted to the viscosity of the medium in the container and must also be small enough to prevent additive from flowing out through the ventilation openings. Fluctuations in the dispensed quantity do not only result from different viscosities, but also due to different fill levels of the medium in the container.
• changes in temperature as a result of the change in the internal pressure in the container result in incorrect delivery.
• the invention has for its object to provide a device which is far simpler and cheaper to produce compared to the prior art, but nonetheless enables trouble-free delivery of the additives.
• the capillary-active layer is in the form of at least one porous band having the capillary openings, which is guided against the wall of the container so that at least a section of the band runs lengthwise extends the outside of the container and can be contacted by the rinse water.
• the porous band When using additives of higher viscosity, for example in gel form, the porous band can be guided along the entire length of the outside of the container, the lower wall area of which at least partially surrounds, so that it covers one or more passage openings in the lower wall area of the container.
• their size and number can be selected in a simple manner.
• the band can have a first section which runs along the inside of the container to an outlet opening and a second section which adjoins the first section at the outlet opening and extends along the outside of the container.
• liquid is sucked out of the inside of the container through the band extending outward through the passage opening and discharged to the outside of the container via the evaporator surface formed by the second section of the band.
• the container can be designed as a refillable container which is open to the atmosphere via a refill opening located in its upper wall area.
• the refill opening can be dimensioned such that the refill can take place directly via a dispensing nozzle of a storage container in question, without having to remove the device from the edge of the pool.
• FIG. 1 shows a perspective view, drawn with the side cover removed, of an exemplary embodiment of the device according to the invention
• Fig. 2 is a partially cut away perspective view of a second embodiment of the device.
• Fig. 3 is a perspective view drawn with the side cover removed of a third embodiment of the device.
• the device shown in Fig. 1 has a container 1 in the form of a so-called plastic shield basket, which can be hooked into a toilet bowl in question by means of an integrally formed on its top holding strap 3, which engages over the edge of the basin, that the outside of the loading - Holder 1 comes into contact with the rinsing water during the rinsing process.
• the container has two shield-shaped side walls, only one of which is visible and is designated by the reference number 5.
• the correspondingly designed other side wall is omitted to make the interior of the container 1 visible.
• Extending between the two side walls is an approximately rectangular cover part 7 and a wall 9 defining the contour of the shield shape and forming a curved surface, which connects the short sides of the rectangular shape of the cover part 7 to one another.
• the wall 9 serves as a carrier for capillary-active material, which is formed in the embodiment shown in the form of two bands 1 1 made of porous material.
• Each band 1 1 extends with a first band section 13 along the inside of each half of the wall 9, which in the area of its top ren, bordering the cover part 7 for each band 1 1 each has a passage cross-section 1 5 adapted to the band cross section, up to which the inner sections 1 3 of each of the bands 1 1 extend.
• a second section 17 of the strips 11 adjoins the passage openings 15. This outer second section 1 7 extends along the outside of the relevant half of the wall 9, covering the area of the inner section 1 3 approximately.
• each band 1 1 forms an extensive evaporator surface for the liquid containing additives, which is sucked up from the inner section 13 of the bands 1 1 by capillary forces to the relevant passage opening 1 5, from where the liquid by capillary action to the respective outer one Section 1 7 migrates and is released from there. This happens during a rinsing process through direct contact with the rinsing water. During periods of non-use, odor-improving substances, if they are provided as a component of the additive, can be released into the ambient air by evaporation.
• the basket-like container 1 has a plurality of through openings 15 in its bottom surface.
• the porous band 1 1 forming the capillary-active layer is guided in this embodiment over its entire length on the outside of the basket-like container 1, in such a way that it extends essentially along the entire extent of the wall 9, which as a curved Surface connects the short edges of the lid part 7.
• the inside of the band 1 1 covers the through openings 1 5, via which the liquid containing additives from the inside of the container 1 arrives directly at the back of the band 1 1, to be released on the outside of the band 1 1, which forms an extensive evaporator surface to become.
• one half of the cover part 7 is formed in one piece with a shell-like side cover 18 which can be clipped onto the housing half of the basket-like container 1 which is in one piece with the other half of the cover part 7.
• a refill opening 19 which, by means of a dispensing nozzle of a storage container for additives, not shown, makes it possible to refill the container 1 without having to remove the device from the toilet bowl. It goes without saying that a corresponding refill opening could also be omitted in the cover part 7 in the embodiment of FIG. 1.
• FIG. 3 differs from that of FIG. 2 only in that only one housing half of the basket-like container 1 on the outside of the wall 9 forming a curved surface has a band 11 covering the through openings 15 as a capillary-active layer.
• the dispensing behavior of the device can be adapted to the respective requirements and the properties of the additives.
• the arrangement shown in FIG. 1 with large-area direct contacting of the inner sections 13 of the belt is preferably suitable for the liquid transport by capillary forces in the range of low viscosities.
• the direct access of the liquid to the band 1 1 via passage openings 15 formed in the bottom of the basket is preferably suitable for higher viscosity ranges, for example gel-like masses.
• the size and number of through openings 1 5 can be selected accordingly for more precise adaptation to specific viscosity values.
• a plastic fleece material, glass, ceramic or sintered plastic material can be used as the capillary-active band 11, for example sintered polyethylene or sintered polypropylene.
• Sponge membranes, so-called Scribrods or fine-pored plastic frits are also possible.
• the additives can be recipes known in the relevant art, such as are shown, for example, in EP 0 775 741 A1.
• Such compositions can have viscosities of 10 to 20,000 mPas at room temperature.
• the device according to the invention can easily meet a wide viscosity range.
