Abstract

The WC holder consists of a container for an active agent preparation to be fitted beneath the rim of a toilet and rinsed over when the toilet is flushed, with at least one inlet and outlet for the flush water and a strap (1) for securing it to the toilet bowl edge. At least a part of the lower region, when in the position of use, of the wall (6) limiting the compartment for active agent preparation is penetrable by aqueous fluids with viscosities of up to 3,000 mPas, but not by tenside-containing pastes with viscosities of over 3,000 mPas. The inlets and outlets (8) for the flush water are arranged in the superimposed region. The holder releases the same quantity of active agents every time the toilet is flushed and they are uniformly distributed in the bowl. Clogging is prevented.

Description

The invention relates to a flush toilet body. It consists of a reservoir which is arranged in a toilet bowl below its edge, which is overflowed during flushing, in which the active ingredient preparation is stored and which has at least one inlet and outlet opening for flushing water and a holder for fixing at the edge of the bowl.

Current_technologies

For the automatic cleaning of toilet bowls, it is known to provide lump-shaped formulations of active ingredients in a cage-shaped container on the inner edge of the toilet bowl. During each flushing process a part of the active substance is released in the flushing water and is distributed together with the water in the bowl. In addition, part of the released active ingredient remains in the siphon and also provides cleaning there.

It uses active ingredient formulations which, on the one hand, can be formed into shape-resistant insoluble blocks and, on the other hand, have sufficient solubility to allow sufficient active substances to be transferred to the water during the short flushing phase. What is important here is that, despite the flushing process, the active substance block remains unchanged after the flushing process.

An example of such a formulation of active ingredients is given

in DE 34 24 317 Al. The composition contains anionic and non-anionic surfactants, perfume, cellulose powder, flushing regulators, inorganic salts, complexing agents, lime-dissolving acids, anti-microbes, plasticizers and other conventional additives.

Also known are disposable flush toilet bodies which must be removed after the active substance block has completely dissolved. Also more advantageous from an ecological point of view are known refillable flush toilet bodies, two of which are described in DE 80 01 994 U1 and DE 34 23 758 A1. Due to the advantage of the multiple usability of the flush toilet body, the disadvantage is that the active substance block and, in some cases, the reservoir itself must be in contact with the hands when refilling. This unpleasant and in some sense unhygienic requirement often discourages consumers from using the flush toilet tank again. The consumer then prefers to use a new, already filled flush toilet body. Another disadvantage is that there is usually no possibility of filling the flush toilet body at any time. Indeed, replenishment is only possible when the active substance block is completely consumed.

These disadvantages are not present with the flush toilet body according to DE 36 39 686 A1. In this embodiment, the body can be refilled without manual contact, since there is a refined funnel formed on the body. In addition, replenishment is possible at any time, since granulate is used instead of a larger block of active ingredient.

The major disadvantage of solid form preparations is the high technical cost and consumption

energy production. Compact pieces are produced by casting or extrusion. Similarly high costs are also required for the production of granulates. Since the individual components of the fragrance and cleansing compositions are initially available in liquid or paste form in the preparation of the formulation, the manufacturing costs of the formulation may be liquid or paste form. Such a liquid or paste would have multiple advantages. Even if the flush toilet body is partially emptied, the active ingredient preparation could easily be refilled or filled. Unlike lump or granular products, production would be simpler and more economical. Unlike the flush toilet body according to DE 36 39 686 A1, no additional measures, such as a filling funnel, would be necessary for contactless replenishment from the storage bottle. A simple filling opening would be sufficient.

However, many unsolved problems have so far been opposed to the use of liquid or pasty preparations for deodorants of flush toilets. Known flush toilet bodies are not applicable to pastes or liquids. Especially after the flushing process, the paste or liquid should not automatically drain or drip from the body. In addition, only a defined fraction of liquid or paste should be dispensed in each flushing process. This dispensed fraction of the active ingredient preparation should be the same for each flushing process. The residue that remains in the flush toilet body should retain the same initial concentration and should not be diluted by the flushing processes performed. After completion of the flushing process, the partially emptied flush toilet body should not be filled with water to prevent the concentration in the top layer from decreasing and the concentrate being diluted and

mud, so there was no uncontrolled delivery of the active substance during the subsequent flushing process.

It is known to dispense a dispenser dispensing device for dispensing a fragrant and / or cleaning agent which is described in DE 34 19 169. However, a tubular, on both sides open receptacle having a capillary active dispensing aid, is provided by conventional clamps on the edge of the bowl. fine fleece materials of plastic or spongy membrane. Around the flushing stream of water, the active substances to be treated in liquid form are taken from the porous dispensing medium and distributed in a toilet bowl. However, the flushing water entering the container does not flow completely out of the container, so that, due to the dilution effect, relatively large amounts of active substances are initially transferred and, in the case of further flushing processes, a smaller amount of active substances. Uneven delivery of active substances represents a significant disadvantage.

Substance_convention

This considerable number of problems are solved in the flush toilet body of the present invention by providing at least a portion in the use position of the lower wall area limiting the filling space for the active ingredient preparation is permeable to aqueous liquids with viscosities up to a maximum of 3,000 mPas but not for a surfactant containing in particular thixotropic pastes with viscosities above 3000 mPas, preferably viscosities above 30,000 mPas, the inlet opening and the outlet opening being arranged in the upper region provided.

According to a particularly preferred embodiment,

lines with viscosities up to 3,000 mPas, but not for surfactant-containing pastes with viscosities above 3,000 mPas, preferably above 30,000 mPas, a permeable wall provided in the interior of the reservoir so that the partially permeable wall and the outer wall create additional space in addition to the filling space. The fine, partially perforated openings are therefore provided inside the flush toilet body and are thus protected from damage. For effluent-enriched excess residual water, the partially permeable wall has an outlet opening in the lower region.

The bottom paste-impermeable reservoir wall prevents the paste of the active substance from dripping between the flushing processes. In the flushing process, the flushing water penetrates through the inlet openings y of the top of the treated area and releases a portion of the active ingredient on the paste surface which is led out of the reservoir through the outlet openings so that the active ingredient is distributed in the toilet bowl. The limit between said lower and upper region, which is defined by the lower edge of the flushing water inlet and outlet openings in the reservoir wall, is at the same time the filling limit for the liquid or pasty active ingredient preparation. In addition, the inlet and outlet openings in the upper region serve to dispense fragrances between the individual flushing processes. If the flush toilet body is partially emptied, the area above the paste would be filled with flushing water, which would gradually dilute the paste, resulting in an undesirable mud effect with drawbacks associated with uncontrolled and uneven delivery of the active ingredient in the subsequent flushing process. This mud or sludge effect is prevented by the partial permeability of the inner wall and the outlet opening. The rest of the flushing water that remains in the flushing body after the flushing process.

* The toilet, flows through the inner wall and through said outlet opening down into the toilet bowl.

On the one hand, the fineness of the openings in the partially permeable wall, which is permeable to the water enriched with the active ingredient preparation but not to the highly concentrated paste, results in the flushing water projecting over the paste at any height of the paste filling state. On the one hand, the paste is prevented from dripping out of the flush toilet body or draining out slowly.

The flush toilet body according to the invention can be designed as a disposable body. It is also possible to provide additional filling of the element without problems and hygienically correctly and thus to create a reusable flush toilet body for liquid to pasty active ingredient formulations.

These fine openings in the partially permeable wall may have different shapes. According to a preferred embodiment of the invention, they are formed as slots with a slot width of 0.2 to 0.8 mm. These slot widths, in particular a slot width of 0.4 mm. have proven particularly advantageous to meet the requirement of partial wall permeability. Moreover, they do not create any technical problems in the manufacture of the flush toilet element.

-r _

Alternatively, the fine holes in the partially permeable wall may also be formed as bores having a diameter of 0.2 to 0.8 mm.

The shape, position and arrangement of the partially permeable wall in the flush toilet body can also be varied. According to a preferred embodiment, the reservoir has a substantially cylindrically symmetrical shape when used with a horizontal longitudinal axis and an annular channel whose restriction is formed by a partially permeable wall and an outer wall. The advantage lies in the small space requirement with respect to the annular channel, which creates a large volume of filling space for receiving the high-viscosity active ingredient preparation.

Preferably, the annular channel is provided over about half the circumference of the reservoir. In use, it is provided in particular on the side of the reservoir which faces the edge of the bowl.

The partially permeable apertures are preferably provided in the region of half the length of the longitudinal reservoir. After each flushing process, the protruding water thus has a short path to these openings and flows accordingly accordingly.

In a preferred embodiment of the invention, the partially permeable wall is provided more horizontally and parallelly in the shape of a comb of the slits. The cost of manufacturing a flush toilet body is further reduced when only one vertical slot is provided in the partially permeable wall *

The flushing flow ratios and thus the even distribution of the active ingredients in the toilet bowl are not disturbed when the reservoir is in the form of a double cone, which has a horizontal longitudinal axis in use. This shape of the container also makes it possible to modify the toilet bowl on the side. The double conical shape of the container has the advantage of being optically demanding.

Furthermore, the proposed fact that the body is provided at

the use of horizontally arranged slotted water inlet and outlet openings provides sufficient water flow through the container.

The filling of the flush toilet body with the product can be carried out without breaking and without touching the container when it has a filling opening for liquid or pasty active substances.

If, under extreme conditions, such as increased water temperature and water, a portion of the paste flows through the fine openings into the next wall, these residues are washed off during the subsequent flushing process if a water inlet opening is provided for the container space formed by the partially permeable wall and outer wall , this is the annular channel of the reservoir. This prevents the fine holes from sticking and clogging.

Preferably the flush toilet body according to the invention is made of polypropylene, in particular by injection molding.

Further advantageous is the fact that the container consists of a transparent material. Thus, when using a colored paste, the consumer can quickly and easily identify the filling condition from the outside.

The body is, as mentioned, preferably used for dispensing pasty combinations of active ingredients which essentially consist of surfactants and perfume oils, in particular also organic and / or inorganic acids and thickeners. Other possible and preferred components of the formulations have already been disclosed in the prior art.

The flush toilet body of FIG. 1 consists essentially of a reservoir with which a holding clamp 7 is connected, by means of which the flush toilet body is arranged inside the rim of the toilet bowl. The reservoir itself has a substantially double cone-shaped configuration, consisting of two conical closures 2, 3, which are connected to the hollow cylindrical central part 4 with the outer wall 5 non-flowingly. Inside

The central part 4 is provided with a partially permeable wall 6, i.e. an inner wall which is arranged parallel to the outer wall 5 over approximately 50% of the length of the periphery of the outer wall 5. Thus, it is formed between the outer wall 5 and the partially permeable wall. 6 annular channel. The semi-cylindrical wall 6 is provided as a semi-cylindrical impermeable wall 6a further into the shutters 2, 3 until it passes on the line 12 (see FIG. 3) into the conical inner wall of the shutters 2,3.

The partially permeable wall 6 is provided with axially extending ridge slots 7 having a width of 0.2 to 0.3 mm, in the exemplary embodiment of 0.4 mm.

Instead of the ridged, axially disposed slots 7 in the embodiment of FIG. 1, in the second embodiment of FIG. 6, a single tangentially extending slot 7 is provided which has the same function. In this case, only a single slot 7 can be provided in accordance with the flush toilet body according to FIG. 6, or more slits 7 arranged tangentially and parallel to one another.

The longitudinal slots 8 in the conical closures 2, 2 form an inlet and an outlet for flushing water. The inlet opening 9 is intended for water flowing through the annular channel, and a corresponding outlet opening 10 is also provided. The reservoir is filled or refilled through the filling opening 11.

The function of the flush toilet body is described below. The pasty, in particular colored article, is pushed from a flexible container, such as a tube or bottle, through a filling opening into a container suspended in a toilet bowl,

A small proportion of flushing water flows through the annular channel through the outlet opening 10. The largest portion of this flushing water enters the filled space with the pasty active ingredient preparation and overflows through the paste. The active substance-enriched water exits through the longitudinal slots 8 of the opposite conical closure 3 and is distributed evenly in the toilet bowl. The residual water which remains between the paste surface and the lowest longitudinal slot 8 and has a viscosity of up to 3,000 mPas does not lead to sludge formation but exits through the slots 7 into the annular channel between the partially permeable wall 6 and the outer wall 5 of the reservoir and flows therefrom This prevents the formation of sludge and ensures an even delivery of the active ingredient. The fineness of the slot 7 prevents the flow of the surfactant-containing active ingredient preparation having a viscosity of 3,000 to 150,000 mPas and in particular a viscosity of from 30,000 to 60,000 mPas.

If the active substance-enriched water residues remain in the slots 7a, they are washed in the subsequent flushing process by flushing water which enters through the inlet opening 9 into the annular channel.

The product can be filled without removing the flush toilet body and without touching the reservoir.

FIG. 6 shows an alternative embodiment of a flush toilet body having only a single, tangentially disposed slot 7 in a further wall 6 instead of the ridge, axially extending slots 7. The functional operation of this embodiment corresponds to the first embodiment. Here, as in the other figures, like reference numerals have the same meaning and are therefore not mentioned again.
