Technique

The invention relates to a VC cup. It consists of a toilet container, which is located below the rim of the toilet, which is flushed during flushing, from the active substance reservoir with at least one flushing water inlet and outlet and one rim mounting bracket VC.

BACKGROUND OF THE INVENTION

For the self-cleaning of a toilet bowl, it is known that the active ingredients are placed in lump form on the inner edge of the toilet bowl. At each flush, a portion of the active agent is released into the flushing water and mixed with the water in the bowl. In addition, some of the active ingredient released remains in the siphon, where it also has a cleaning effect.

Active substances are used which, on the one hand, may be in the form of an insoluble storage cylinder and, on the other hand, have sufficient dissolution capacity to release sufficient active substances during the short flushing phase. In addition, it is important that the flushing cylinder remains unchanged except for the fragrance release.

An example of such an active agent is given in DE 34 24 317 A1. The composition comprises anionic and nonionic surfactants, fragrance, cellulosic powder, wash regulators, inorganic salts, complexing agents, limescale acids, antimicrobial agents, plasticizers, and other conventional ingredients.

Disposable VC cups are known which must be removed after the active substance has been completely emptied. However, from the ecological point of view, VC baskets which can be refilled are also known, two of which are described in DE 80 01 994 U1 and DE 34 23 758 A1. On the other hand, the advantage of reusing a VC cup has the disadvantage that the active substance cylinder and in some cases the cup itself must come into contact with the hands when refilling. Such a procedure, not pleasant and in some sense unhygienic, leads the user not to use the new cartridge. He gets a new cupcake including a refill. Another disadvantage is that the possibility of replenishing the basket at any time is missing. It can only be filled when the active substance cylinder is completely consumed.

These disadvantages do not occur in the basket according to DE 36 39 686 A1. Here it is possible to fill the basket without touching the hands, as a watering funnel is attached to the basket. In addition, it is also possible to fill the basket at any time, since granulate is used instead of the active agent roller.

One of the basic drawbacks of solid effective means is high technological costs and energy consumption during production. The compact pieces are produced by a liquid and extrusion process. Similarly high costs are also required for the production of granules. Since the individual components of the fragrance or cleaning agents are initially in the form of a liquid or paste, the manufacturing costs could be reduced if the form of the composition were chosen in liquid or paste form. Such a liquid or paste would have several advantages. Even if the VC basket is partially emptied, the effective agent could be refilled and filled without problems. In contrast to lumpy or granular compositions, production would be simpler and cheaper. In contrast to the VC cup according to DE 36 39 686 A1, no other means such as a filling funnel would have to be used for contactless filling from the cartridge bottle. A simple filling opening would suffice.

However, the introduction of liquid or paste formulations for VC deodorants is associated with a number of unresolved problems.

The known VC cups are unsuitable for pastes and liquids. Namely, the paste and liquid must not spill from the cup spontaneously after the flushing. In addition, only a certain portion of the liquid or paste should be released during each flush. This released amount of active agent should be the same for each flush. The product remaining in the basket must retain the same concentration as initially and must not be diluted with subsequent flushing. After the flushing, the partially emptied VC cup must not be filled with water from the primary level 2: in order not to decrease the concentration and to dilute the concentrate, the so-called concentrate. muding and thus uncontrolled release of the active ingredient in the subsequent flushing.

DE 34 19 169 A1 discloses a pendant embodiment at the edge VC with dispensing of a fragrance and / or cleaning agent. The receptacle with an opening on both sides with the usual attachment to the rim of the VC contains a capillary-active auxiliary dispenser, for example a fine plastic-textile material or a sponge membrane. The flow around the running water releases the active substances from the porous dispensing medium and divides them into a toilet bowl. However, the water flowing into the container does not completely flow out of it, so that, due to further dilution, relatively large amounts of active substances are always released during subsequent flushing. The uneven release of the active substances thus constitutes a real disadvantage.

This multifaceted problem of the VC cup according to the present invention is solved by the fact that at least a portion in the lower part of the filling space of the bounding agent wall is permeable to liquids with a viscosity of at most 3000 mPas but not for liquids containing surfactants, in particular thixotropic pastes greater than 3000 mPas, preferably with viscosities higher than 30 000 mPas, and there are inlet and outlet openings in the region above it. .

In a particularly preferred embodiment of the invention, the inner wall of the container is adapted to be permeable to liquids having a viscosity of at most 3000 mPas but not for surfactant-containing fluids, a paste having a viscosity of greater than 3000 mPas, preferably having viscosities greater than 30,000 mPas so that the partially permeable wall and the outer wall constitute an additional space of the filling space. The fine partially through holes are therefore located inside the VC of the basket and are thus protected from damage. To discharge excess active-enriched water, the partially permeable wall has a discharge opening in the lower part. The lower paste-impermeable area of the container wall prevents the paste of active substance from dripping between flushing, during flushing water enters the area above it through the discharge openings, dissolves some of the active substance on the paste surface and leads it through the discharge openings again out of the reservoir. the active ingredient is distributed into a toilet bowl. The boundary between said lower and above-lying region, which is determined by the lower edge of the planned flushing water inlet and outlet openings in the reservoir wall, is also the filling limit for both the liquid and paste-like active agent. The inlet and outlet openings at the top also serve to release fragrances between the individual flushings. For a partially emptied VC cup, the area should be above. the paste was filled with water, which would dilute the paste constantly, thus giving rise to an undesired mud effect which would result in uneven and uncontrolled release of the active ingredient during subsequent flushing operations. The mud effect is prevented by the partial permeability of the inner wall and the discharge opening. The rest of the flushing water after flushing in the VC basket drains through the inner wall and through the downstream opening into the toilet bowl.

Due to the fineness of the openings in the partially permeable wall, which is permeable to the water-enriched active substance but not to highly concentrated pastes, it is possible to achieve the flushing water standing above the paste at any height of the paste completely. On the other hand, the paste is prevented from slowly dripping or flowing through these fine VC cup openings.

The VC cup of the invention may be constructed as a disposable cup. It is technologically possible to achieve a hygienic filling of the VC basket without much expense and thus it can be used multiple times for liquid to pasty active agents.

The fine openings in the partially permeable wall may have different forms. Thus, in a preferred embodiment of the invention, they may be in the form of slots with a width of 0.2 to 0.8 mm. These slot widths, and in particular the slot width of 0.4 mm, have proved to be very suitable in terms of meeting the partial permeability of the wall. In addition, there are no technical problems in the manufacture of such VC baskets.

Alternatively, the openings in the partially permeable wall may also be in the form of holes with a diameter of 0.2 to 0.8 mm.

The shape, position and arrangement of the partially permeable wall may vary. Advantageously, in certain cases, the cylindrical shape of the container is used in a horizontal axis and with a prestigious channel, forming a boundary from the semi-permeable wall and the outer wall of the container. The advantage lies in the need for a small space due to the circular channel, which leaves a large volume for the filling space for the highly viscous active agent.

Preferably, the annular channel is located above about half the volume of the cartridge. It is especially planned on the side of the dispenser towards the edge of the toilet bowl.

The partially permeable apertures are preferably located in the region of the half length of the longitudinal container. In this way, the water remaining after each flushing has a relatively short distance to these openings and flows accordingly quickly.

In a preferred embodiment of the invention, a plurality of horizontally and ridge-extending slits are placed on the semipermeable wall. The cost of making the VC basket is further reduced if, alternatively, only a single vertically extending slot is provided in the semi-permeable wall.

The flow properties of the flushing stream and the associated uniform distribution of the active ingredients in the toilet bowl are maintained in a double-conical container with use in the horizontal axis. Such a shape of the reservoir also allows it to be placed on both side walls of the toilet bowl. The double cone shape has an additional optical advantage.

Furthermore, the proposed, horizontally arranged slots of the inlet and outlet openings for the flushing water guarantee a sufficient flow of water through the reservoir.

Filling the VC basket with fabric is possible without dismantling and without touching the cartridge, since a filling opening for liquid or pasty-like active substances is provided.

If in extreme cases, e.g. at an elevated water temperature and an increased amount of water, a portion of the paste has passed through the fine openings into the next wall, so these residues are washed away at the next flushing because the water is released from the reservoir area in the area of water passages in the partially permeable wall (annular channel) is designed. This prevents the fine holes from sticking and jamming.

Preferably, the VC basket according to the invention is made of polypropylene, especially made by die-casting.

Another advantage is if the container is of transparent material. When using the color paste, the user can observe the condition of the cartridge from the outside, simply and without problems.

The basket made as above may be used to dispense a pasty combination of active ingredients which in fact consist of surfactants and perfumed oil, in particular also organic and / or inorganic acids and a thickener. Other possible and preferred components of the compositions have been described in the prior art discussion.

The invention will now be described by way of example with reference to the drawings.

DETAILED DESCRIPTION OF THE INVENTION

The VC cup of FIG. 1 consists essentially of a dispenser and a retaining clip 1 associated therewith, which is a VC cup attachable from the inside to the edge of the toilet bowl. The container itself has a substantially double-conical shape, consisting of 2 conical caps that are impermeable to the concave cylindrical central portion 4 by an outer wall. Inside the central part 4, a wall 6 is often permeable, i.e. as an inner wall, which extends parallel to the outer wall over a length of more than 50% of the circumference of the outer wall. Thus, an annular channel is formed between the outer wall 5 and the partially permeable wall 6. The semi-cylindrical wall 6, like the impermeable, as well as the semi-cylindrical wall 6a, continues to pull inwardly the cones of the closing caps 2, 3 until it reaches the conical inner wall of the closing caps 2, 3 along the path 12 (FIG. 3).

The partially permeable wall 6 is provided with axially extending ridge-like slits, with slits width from 0.2 to 0.8 mm, in the exemplary embodiment from 0.4 mm.

Instead of the ridge-like, axially extending slot 7 in the embodiment of FIG. 1, in the second embodiment of FIG. 6, a single tangentially extending slot has the same function. In this case, a single slot 7 or even several tangentially and mutually parallel slots can be used in the VC basket.

The longitudinal slots 8 in the conical caps 2, 3 serve as openings for inlet and outlet of flushing water. The opening for the inlet of water through the annular channel has a marking 9, the corresponding discharge opening has a marking 10. The reservoir is filled or replenished through the filling opening 11.

The function of the VC canister is described in turn. The pasty, particularly colored fabric is from a flexible container, e.g. from the tube or bottle pushed through the filling opening into the container hung at the edge of the toilet bowl such that the container is filled just below the longitudinal slot 8. In the translucent container, the color of the paste allows to recognize the state of the amount of filling.

When flushing, water enters through the longitudinal slits, e.g. the closing cap 2 into the reservoir. A small part of the flushing water flows over the annular channel through the drain hole. The largest part of this water enters the active substance chamber (filling space), which is filled with a pasty active agent and floods the paste. The water enriched with the active agents exits through the longitudinal slit 8 opposite the conical-shaped closing cap 3 and is distributed evenly into the toilet bowl. The water remaining between the paste surface and the lowermost longitudinal slot 8, which has a viscosity of up to 3000 mPas, does not cause compaction, but passes through the slot 7 into the annular channel between the partially permeable wall 6 and the outer wall of the reservoir 5. This prevents muds and ensures an even release of the active agent. The fineness of the slot 7 prevents leakage of the surfactant-containing active composition having a viscosity of from 3,000 to 150,000 mPas and in particular a viscosity of from 30,000 to 60,000 mPas.

If the remnants of water remain enriched in the slots 7 and accumulate there, they would be washed away by the flushing water passing through the inlet opening 9 in the annular channel at the next flush.

The effective agent can be filled without removing the VC basket and without touching the container.

Fig. 6 illustrates an alternative method of making a VC basket that has only a single tangentially extending slot instead of a ridge-like axially extending slot. In terms of efficiency, construction in this way provides the same efficiency as in the first embodiment. Here, as in the figures, the same designations have the same meaning and will therefore not be listed again.
