Abstract

In the present invention, there is disclosed a WC holder consisting 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 (8) 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 mPa.s, preferably in the range of 3000 to 150 000 mPa.s, but not by tenside-containing pastes with viscosities of over 3,000 mPa.s. 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

Technical field

FIELD OF THE INVENTION The present invention relates to a flush toilet body comprising a reservoir which is disposed in a toilet bowl below the rim of the flush and overflows with flushing and in which a highly viscous, liquid, wetting agent-containing surfactant is stored and which has at least one inlet and outlet opening for a flushing water and one holder for attaching to the rim of the bowl, wherein at least one partially permeable portion, in the position of use, of the lower wall region delimiting the filling space for the active agent is particularly permeable to water but not to the active agent. The invention also relates to the use of such a flush toilet body for dispensing pasty compositions containing active ingredients.

BACKGROUND OF THE INVENTION

For the automatic cleaning of toilet bowls, it is known to provide effective lumpy formulations in a cage-shaped container on the inner edge of the toilet bowl. During each flushing process, part of the active ingredient is released into 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.

Effective agents are used which can be formed into shape-resistant insoluble blocks on the one hand, and on the other hand they have sufficient solubility to allow sufficient active substances to be transferred to the water during the short flushing phase. Importantly, the block of active substance remains unchanged after flushing, taking into account the release of odor.

An example of such an active ingredient composition is given in DE 34 24 317 A1. This preparation contains anionic and non-anionic surfactants, perfume, cellulose powder, flushing regulators, inorganic salts, complexing agents, lime-soluble acids, anti-microbes of the active ingredient, plasticizers and other conventional additives.

There are also known disposable flush toilet bodies which must be removed after the active substance block has completely dissolved. It is also known from the ecological point of view to fill flush toilet bodies, two of which are described in DE 80 01 994 Ulav 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 also have to be in contact with the hands during refilling. This unpleasant and, in some respect, unhygienic demand of the consumer often discourages the flush toilet body from being used again. Therefore, the consumer prefers to use a new, 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 eliminated 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 provided a body-shaped filling funnel. In addition, replenishment is possible at any time, since granulate is used instead of a larger block of active ingredient.

A major disadvantage of solid formulations is the high technical cost and energy consumption of the manufacturing process. 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 cleaning components are initially available in liquid or paste form in the manufacture of the composition, the manufacturing cost could be reduced if the

The liquid or vapor-like form of the composition. Such a liquid or paste would have multiple advantages. Even if the flush toilet body is partially emptied, the active agent-containing agent could be replenished or filled without problems. 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 the use of 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 paste compositions 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 at each flush. This dispensed part of the active ingredient-containing composition should be the same for each flush. The remainder remaining in the flush toilet body should retain the same initial concentration and should not be diluted by the flushes performed. At the end of the flushing, the partially emptied flush toilet body should not be filled with water in order to prevent the concentration in the top layer and the dilution of the concentrate, i.e. the so-called mud, from being reduced and thus uncontrolled dispensing of the active substance during subsequent flushing.

It is already known to dispense a dispensing device for dispensing a perfume and / or cleaning agent into a toilet bowl as described in DE 34 19 169 A1. The tubular, open-ended container, which is open to both sides by means of conventional bowl clamps, has a capillary-active dispensing aid, for example fine non-woven plastic or spongy membrane materials. 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 penetrating into the container does not completely drain from the container, so that a relatively large amount of active substances, but still less active substances, is initially transferred by the dilution effect. Uneven dispensing of the active substances represents a significant disadvantage.

DETAILED DESCRIPTION OF THE INVENTION

The flush toilet body according to FIG. 1 consists essentially of a reservoir with which the holder 1 is connected, by means of which the flush toilet body is fixed internally at the edge of the toilet bowl. The reservoir itself has a substantially double cone shape, consisting of two conical shutters 2, 3, which are rigidly connected to the hollow cylindrical central part 4 with the outer wall 5. Inside the central part 4, a partially permeable wall 6, i.e. a wall which is arranged parallel to the outer wall 5 for about 50% of the length of the periphery of the outer wall 5. Thus, an annular channel is formed between the outer wall 5 and the partially permeable wall 6. The semi-cylindrical, partially permeable wall 6, like the semi-cylindrical impermeable wall 6a, extends 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 positioned, ridge slots 7 with a width of 0.2 to 0.8 mm, in the exemplary embodiment 0.4 mm.

Instead of the ridged, axially extending 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, as shown in FIG. 6, or even more tangentially and mutually parallel slots 7 can be formed.

Inlet and outlet openings 8 in the form of slots are provided as inlet and outlet openings for flushing water in conical closures 2, 3. The inlet opening 9 is intended for water flowing through the annular channel, and a corresponding outlet opening 10 is also provided here. 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, means is pushed from a flexible container, for example a tube or bottle, through a filling opening 11 into a container suspended in a toilet bowl, the container being filled just below the lower edge of the inlet and outlet openings 8. fulfillment.

Upon flushing, water enters the reservoir through the inlet and outlet openings 8 provided, for example, in the closure 2. A small part of the flushing water flows through the annular channel through the outlet opening 10. The largest part of this flushing water enters the filled space with a pasty composition containing the active substances and flows over the paste. The active substance-enriched water exits through the inlet and outlet openings 8 of the opposite conical closure 3 and is distributed evenly in the toilet bowl. The residual water remaining between the paste surface and the lower inlet and outlet openings 8 has a viscosity of up to 3000 mPa.s, does not lead to sludge formation but exits through the slits 7 into the annular channel between the partially permeable wall 6 and the outer wall 5 of the reservoir. 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 active ingredient-containing composition which contains surfactants and has a viscosity in the range of 3000 to 150 000 mPa.s, in particular in the range of 30 000 to 60 000 mPa.s.

-4GB 296388 B6

If the active substance-enriched water residues remain in the slots 7 and continue to flow out, they are washed in the subsequent flushing with flushing water which enters the annular channel through the inlet opening 9.

Filling with effective agent can be done without removing the flush toilet body and without touching the reservoir.

FIG. 6 shows an alternative embodiment of a flush toilet body having only one tangentially extending slot 7 in the partially permeable wall 6 instead of the ridge-axially extending slots 7. The function 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 re-introduced.
