Description

DEVICE FOR DISPENSING AN ACTIVE-SUBSTANCE PREPARATION INTO A TOILET BOWL}

The present invention relates to a multichamber device for dispensing the active ingredient preparations into the toilet bowl, which device comprises a receiving container for the active ingredient formulation, which is disposed in the toilet bowl, usually below the toilet bowl rim, and the present invention is also provided when flushed. And water flowing over the device.

For the automatic cleaning of toilet bowls, active ingredient preparations (“toilet bowl blocks”) in block form and / or essentially solid form are known in cage-type receiving containers on the inner rim of the toilet bowl. With each flushing action, a portion of the active ingredient formulation of the toilet block is dissolved in flush water and distributed with the flush water into the toilet bowl. Such a device is known, for example, from EP 2310582 (A1). In addition, a smaller portion of the dissolved active ingredient formulation remains in the residual water in the toilet bowl and also ensures cleaning of the toilet bowl. However, the amount of active ingredient formulation remaining in the toilet bowl after the flushing operation is very small.

In addition, the same problem exists for devices for dispensing liquid active ingredient formulations (toilet baskets). Such a device is known, for example, from EP 1334239 B1.

Thus, one important disadvantage of all toilet baskets is that the dosing of all different active ingredient formulations that are present in the receiving container and optionally also occur essentially simultaneously and during the flushing operation. As a result, active ingredient preparations that exhibit their effect after the start of the flushing operation or at least partially at the end of the flushing operation cannot function optimally.

Therefore, it is an object of the present invention to further improve the device for dispensing the active ingredient preparations into the toilet bowl, so that dispensing the active ingredient preparations into the toilet bowl occurs at an optimal point in time.

This object is achieved by a device having the features of claim 1. Preferred embodiments are described in the dependent claims.

The device according to the invention for dispensing the active ingredient preparations into the toilet bowl comprises a receiving container disposed in the toilet bowl, which can be fastened to the toilet bowl. The receiving container includes one first chamber and at least one second chamber. The first chamber dispenses the first active ingredient formulation into the toilet bowl when flush water flows over the first chamber, and the second or additional chamber acts as the second active when flush water flows over the second or additional chamber. The ingredient preparation or additional active ingredient preparation is dispensed into the toilet bowl. The chambers are such that at least the first active ingredient formulation and the second active ingredient formulation or additional active ingredient formulation are dispensed into the toilet bowl at staggered intervals, and at least one of the active ingredient formulations is timed for the flushing operation. It is designed to dispense into the toilet bowl. If there are two or more chambers, then the additional chambers are first active ingredient formulations, which are dispensed into the toilet bowl at different times or preferably at the same time as the corresponding formulations from the first or second chamber. It may also contain 2 active ingredient preparations or further active ingredient preparations again. However, the additional chambers may also contain one or more additional active ingredient formulations that can be dispensed into the toilet bowl in sequence, either simultaneously with one of the other formulations or at intervals.

In the sense of the present invention, “active ingredient preparation” is understood to be a liquid, gelatinous or solid preparation, which is partially dissolved when the preparation comes into contact with flush water and then contains the active ingredient. Solution can be dispensed into the toilet bowl as a mixture of flush water and active ingredient. Solutions containing these active ingredients may also form in the receiving container when flush water can flow through, for example, a solid or gelatinous toilet cleaning block and be dispensed into the toilet bowl.

The gap difference allows targeted distribution of the same or different active ingredient formulations into the toilet bowl at different times. The routine flushing process within a conventional toilet bowl has two characteristic points in time: the start of flushing and the end of flushing. These time points define time windows: before the flushing operation, during the flushing operation, and after the flushing operation. The first active ingredient preparation and the second active ingredient preparation are preferably different. Since different active ingredient preparations may have different functions, it is often desirable to dispense different active ingredient preparations at different time points during the flushing process to optimally achieve these functions. This optimized distribution saves the active ingredient formulation and achieves the best performance.

A device according to the invention which does not have an additional mechanism, for example an electrical mechanism for the independent dispensing of the active ingredient, is capable of dispensing the active ingredient preparation out of the first chamber and into the flush water at the start of the flushing operation at the earliest. Can, and thus dispense into the toilet bowl. Thereafter, flush water flows through the first chamber, inter alia, penetrates into the first chamber through the inlet, and is a solution containing the active ingredient rich in the first active ingredient, after which the flush water flows through the first active ingredient formulation. , Out of the first chamber, through the outlet, and in the direction of the toilet bowl. Similarly, the second active ingredient formulation flows from the second chamber into the toilet bowl, but the second active ingredient formulation is dispensed at intervals.

The first chamber and the second chamber are designed such that, in the same overflow, the first active ingredient formulation and the second active ingredient formulation are dispensed into the toilet bowl at a distance from each other. In the sense of the present invention, the time difference distribution of the active ingredient preparation into the toilet bowl means:

Iv) the dispensing of at least two different active ingredient formulations is initiated at at least two different time points for the flushing operation, and / or

Ii) Dispensing of the at least two different active ingredient formulations ends at at least two different time points for the flushing operation.

Thus, the dispensing of the second active ingredient preparation can start, for example, at least 1 s after the start of the dispensing of the first active ingredient preparation, preferably after at least 2 s, for example the first active ingredient preparation Lasts longer for at least 1 s, preferably at least 2 s than the distribution of.

There are different types of toilet bowls with different flushing ratios and flushing times. The device according to the invention is designed for a toilet bowl in a flushing operation, in which flushing water flows through at least one position on the inner wall of the toilet bowl. Therefore, the device according to the present invention is particularly suitable for a toilet bowl according to standard EN 997 (2003 + A1: 2006) class 1.

The concept of “same overflow” in the sense of the present invention also contemplates the simultaneous initiation of overflow, in particular. The device preferably comprises a flush water distribution element, for example a distributor plate as is known from EP 2310582, said flush water distribution element being operated by the flush water during flushing and the flush water distribution element being operated by the flush water during flushing. It is arranged and configured to distribute evenly into all chambers.

The time difference is preferably achieved by a time delay device. The time delay device is placed in a flush water stream that can flow through one of the chambers to affect the flow.

In a preferred variant of the invention, the time delay device is arranged such that the current outflow from the chamber is affected. Examples of time delay devices inside the chamber include:

(Iii) outlet holes with fewer and / or smaller diameters compared to other chambers not equipped with a time delay device, such that the outflow from the chamber starts at a fairly late time point and / or proceeds more slowly;

(Ii) a lower outlet opening disposed over the bottom plate of the chamber such that it is first filled to the height of the lower outlet opening before the chamber is emptied;

(Iii) a pipe fixed into the chamber as an outlet so that it is first filled up to the height of the inner end of the pipe before the chamber is emptied;

(Iii) Triggering limit level and end limit level for flush water with a solution containing the active ingredient in the receiving chamber are defined, and also the outflow of flush water with a solution containing the active ingredient can be initiated and / or ended. Siphon. Preferred variants for the time delay device are described in more detail below.

In one embodiment of the present invention, at least one of the first chamber and the second chamber, preferably the second chamber, comprises a time delay device.

In another embodiment of the present invention, the second chamber includes a time delay device, and the first chamber has another time delay device with a different time delay than the time delay device of the second chamber. In another embodiment of the present invention, the second chamber has a time delay device, while the first chamber does not. Thus, the first active ingredient formulation from the first chamber is dispensed out of the first chamber and into the toilet bowl immediately after the start of overflow of the receiving container. In this case, the time interval between initiation of overflow of the receiving container and distribution out of the first chamber is much shorter than 1 s, preferably shorter than 0.2 s. Essentially, in the sense of the present invention, the time delay must be provided if the chamber can flow out of one chamber at a rate equal to or faster than the flush water capable of flowing a defined amount of flush water into each chamber. It is not necessary to have a device.

In a preferred embodiment of the present invention, the outlet opening (s) of the second chamber has a smaller total cross-sectional area relative to the first opening (s) of the first chamber. For example, if the number of outlet openings in each chamber is the same, each outlet opening in the first chamber has a respective diameter larger than the outlet openings in the second chamber. Although in the same overflow, the first chamber and the second chamber simultaneously receive flush water, flush water with a solution containing the active ingredient flows out of the second chamber more slowly due to the smaller total cross-sectional area of the outlet openings, and thus The distribution of the active ingredient preparation from the second chamber takes place over a longer period. Due to this variant, the time difference can achieve the distribution of the active ingredient with respect to the actual flushing operation in a very advantageous manner.

In another advantageous embodiment of the invention, the second chamber with a time delay device has fewer outlet openings than other chambers without a time delay device. Optionally, only one outlet opening is present in the second chamber. Due to the smaller number, only a smaller amount of flush water can flow out during the same period, so that a time difference is achieved for the first chamber with more outlet openings.

In another embodiment of the invention, the time delay device is designed as a pipe which is preferably arranged at the bottom of the second chamber and preferably projects into the second chamber.

In a particularly preferred embodiment of the invention, the time delay device is a siphon. It has been found that chambers with smaller capacities are filled with flush water fairly quickly during the flushing operation and have less control over the time delay setting of the onset of spillage. On the other hand, it has been found that the siphon can be designed in a very flexible manner, so that the outflow can be delayed for a few seconds compared to the start of flushing even in less chambers. Therefore, siphon is a preferred time delay device. In addition, siphon is preferred for chambers having a water collection capacity of 50 cm 3 or less, even more preferably 30 cm 3 or less. In a preferred variant having a siphon, the siphon comprises a pipe and a lead disposed on the pipe.

Due to the time difference distribution of the active ingredient preparations at intervals, a targeted distribution of active ingredient preparations, especially different active ingredient preparations, is possible at several time intervals during the flushing operation. Therefore, a particularly effective and targeted distribution of each active ingredient at the optimum time point is ensured without the use of a complex conditioning unit.

In one embodiment of the present invention, the first active ingredient formulation and the second active ingredient formulation contain ingredients that are incompatible with each other. If these components are present simultaneously in the formulation, these components may, for example, proceed in an undesired chemical reaction with each other, or lead to phase separation. However, they may be different colorants, and mixing of the colorants in a single step will lead to altered and undesirable color marks. For example, examples of components that are incompatible with each other include bleach and colorants or fragrances or proteolytic enzymes and other enzymes. Other embodiments are well known to those skilled in the art. Due to the time distribution, the two active ingredient preparations can at least partially show their effect independently of one another.

In another embodiment of the present invention, the first active ingredient formulation and the second active ingredient formulation are compatible with each other, but the first active ingredient formulation and the second active ingredient formulation must be of the device because they must exhibit their effects at different times. It is stored in different chambers. In a preferred refinement, the first active ingredient formulation and the second active ingredient formulation contain different active ingredients of the same class of active ingredients (but chemically different). Thus, for example, different surfactants or different enzymes may be used. Moreover, the first active ingredient preparation and the second active ingredient preparation may contain the same ingredients in different concentrations.

In one embodiment of the present invention, the second active ingredient preparation comprises at least one active ingredient which exhibits its effect mainly after the flushing operation. An example of such an active ingredient is a water-soluble colorant that colors flush water, and a blue color is preferred. Due to the clear flushing even after the end of the flushing operation, these colorants are not flushed, but instead remain in the toilet bowl at a sufficient concentration, i.e. the colorants remain in the toilet bowl to color this flush water, preferably blue. Still exists within. Further examples of activator ingredients that exhibit their effect even or primarily after the end of the flushing operation are: fragrances, and ingredients that dissolve lime and urine deposits, shiny surfactants, such as anti-soil repellant) clear rinses and substances to increase active ingredients or active ingredients to control malodors, disinfectants and / or bleach, foam boosters.

In another embodiment of the invention, one of the active ingredient preparations mainly comprises an active ingredient which exerts its effect during the flushing operation, for example a surfactant that forms a foam. The flushing operation is used to form bubbles by mixing air and flush water, which is rich in surfactant. These surfactants must be dispensed into flush water during the flushing operation to prevent excessive distribution of surfactant active ingredients.

Another example is an active ingredient formulation that requires cleaning the toilet bowl by chemical mechanical cleaning. It should be dispensed during the flushing operation and preferably should be started immediately at the start of the flushing operation. Abundant flush water flow ensures a mechanical part of the toilet bowl cleaning.

They are preferably in the form of solid, gelatinous, or liquid active ingredient in an amount of from 0.01 to 10% by weight, in particular from 0.05 to 8% by weight, particularly preferably from 0.1 to 5% by weight, i.e. as toilet blocks or toilet cleaners exist. One perfume component that may be present is d-limonene. In a particularly preferred embodiment, the active ingredient preparation contains adhesive scents, in particular ethereal oil (known as essential oil). For example, these include pine oil, citrus oil, jasmine oil, patchouli oil, rose oil or ylang-ylang oil that can be used within the meaning of the present invention. Also suitable are clary sage oil, chamomile oil, lavender oil, chrysanthemum oil, melissa oil, mint oil, cinnamon leaf oil, linden blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and lapdanum In addition to oils, there are orange blossom oil, neroli oil, orange peel oil and sandalwood oil. However, within the scope of the present invention, other boiling cents, such as cents of high boiling point and / or solid cents of natural or synthetic origin, and also more volatile cents, may be used alone or in mixtures in particular. Low boiling cents of natural or synthetic origin are advantageous for use in perfume oils. In addition, agents used in different chambers to contain different fragrances may be desirable, such that the influence of the fragrance changes after the end of the flushing operation. Moreover, after the end of the flushing operation, an agent used in different chambers to contain the same, but different concentrations of fragrance, may also be desirable, such that the fragrance is sensed with different intensity.

Chelating agent

Complexing agents (INCI: chelating agents) are also known as metal ion sequestrants. These are components that enable chelating and inactivation of metal ions to prevent adverse effects on the stability or appearance of the formulation, for example turbidity. On the one hand, it is important to chelate calcium ions and magnesium ions that cause water hardness and are incompatible with numerous components. On the other hand, ion chelation of heavy metals such as iron or copper delays the oxidative decomposition of the finished formulation. In addition, the chelating agent supports the cleaning effect.

coloring agent

Agents that can be used according to the invention contain one or more dyes (INCI; Colorants) as additional components. Both water-soluble and oil-soluble colorants may be used, but on the one hand, their compatibility with other components, such as bleach, should be considered, and on the other hand, despite the prolonged exposure, the colorant used is a toilet ceramic. Should not have a real impact on This is advantageous if the second active ingredient formulation comprises a water soluble colorant (preferably a blue color) that colors the flush water. The flushing water colored with this colorant is present in a sufficient concentration in the toilet drainage tank due to post-run after the end of the actual flushing operation, i.e. it is in the residual flushing water stagnated in the toilet bowl to color the flushing water, preferably blue. Remains. The colorant is preferably present in an amount of 0.0001 to 0.1% by weight, particularly 0.0005 to 0.05% by weight, particularly preferably 0.001 to 0.01% by weight.
