Description

The invention relates to a multi-chamber device for dispensing active ingredient preparations in a toilet bowl with a typically in the toilet bowl below the edge to be arranged, overflowed during rinse receptacle for the preparation of active ingredient.

For the automatic cleaning of toilet bowl it is known to attach active ingredient preparations in lumpy or substantially solid form ("WC blocks") in a cage-like receptacle on the inner edge of the toilet bowl. At each flushing part of the active ingredient preparation of a toilet block dissolves in the rinse water and is distributed together with the rinse water in the toilet bowl. Such a device is eg off EP2310582 (A1) known. In addition, a smaller part of the dissolved active ingredient preparation remains in the residual water of the toilet bowl and also ensures there for a cleaning. However, the amount of active ingredient preparation that remains in the toilet bowl after flushing is quite low.

The same problem also exists for devices (toilet bowls) for dispensing liquid active substance preparations. Such a device is for example off EP1334239 B1 known.

A major disadvantage of all these toilet bowls is therefore that the dosage of all possibly present in the receptacle different drug formulations substantially simultaneously and during the flushing process. This has the consequence that active ingredient preparations which should have their effect after the beginning or at least partially after the end of the rinsing process can not function optimally.

The object of the invention is therefore to improve a device for dispensing active compound preparations in a toilet bowl so that the delivery of the active ingredient preparations takes place in a toilet bowl at the optimum time.

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

The inventive device for dispensing active ingredient preparations in a toilet bowl comprises a receptacle to be arranged in the toilet bowl, wherein the receptacle is attachable to the toilet bowl. The receptacle comprises a first chamber and at least one second chamber. The first chamber is in overflow of rinse water from a first preparation of active ingredient in the toilet bowl and the second or further chamber is at overflow of rinse water a second or further preparation of active ingredient in the toilet bowl. The chambers are designed so that at least the first active ingredient preparation and the second or further active ingredient preparation both delayed in time from each other and at least one of the active ingredient preparations are released with respect to the rinsing delayed in the toilet bowl. If more than two chambers are present, the further chambers can again contain the first, second or further active compound preparation which are dispensed into the toilet bowl at other times or preferably at the same time as the corresponding preparations from the first or second chamber. However, they can also contain one or more further active compound preparations, which in turn can be dispensed into the toilet bowl either simultaneously with one of the other preparations or else with a time offset.

For the purposes of this invention, a "preparation of active compound" is understood as meaning a liquid, gelatinous or solid preparation which, on contact with rinsing water, is dissolved by the latter and subsequently used as active ingredient-containing solution, ie. H. Mixture of rinse water and active ingredient can be dispensed into the toilet bowl. Such an active ingredient-containing solution can also be formed, for example, by the overflow of a solid or gel WC cleaning block through the rinse water in the receptacle and then be delivered to the toilet bowl.

The temporal offset allows the targeted delivery of the same or different active ingredient preparations at different times in the toilet bowl. An ordinary flushing operation within a common toilet bowl has two characteristic times, namely the start of flushing and the flushing end. These times define the time windows: before the rinsing process, during the rinsing process, and after the rinsing process. The first and the second active compound preparations are preferably different. Since different active ingredient preparations may have different functions, it is often useful to deliver different active ingredient preparations at different times in the course of the rinsing process to optimally fulfill these functions. Such an optimized delivery saves active ingredient preparation and achieves the best performance.

The device according to the invention, which does not have an additional, for example electrical, mechanism for the independent release of active ingredient, can deliver the preparation of active compound from the first chamber into the rinsing water and thus into the toilet bowl at the beginning of the rinsing process. Among other things, the rinsing water flows over the first chamber and penetrates into the first chamber via an inlet, overflows the first active ingredient preparation, and flows as an active ingredient-containing solution enriched with the first active ingredient preparation via an outlet out of the first chamber in the direction of the toilet bowl. Analogously, the second active ingredient preparation passes from the second chamber into the toilet bowl, but the delivery takes place with a time delay.

• i) die Abgabe der mindestens zwei unterschiedlichen Wirkstoffzubereitungen in Bezug auf den Spülvorgang zu mindestens zwei verschiedenen Zeitpunkten einsetzt und/oder
• ii) die Abgabe der mindestens zwei unterschiedlichen Wirkstoffzubereitungen in Bezug auf den Spülvorgang zu mindestens zwei verschiedenen Zeitpunkten endet.

The first and the second chambers are designed such that, given the same overflow, the first active ingredient preparation and the second active ingredient preparation are dispensed with a time offset from one another into the toilet bowl. The staggered release of active compound preparation in the toilet bowl means according to the invention that:

• i) the delivery of the at least two different active compound preparations in relation to the rinsing process at least two different times and / or
• ii) the delivery of the at least two different active substance preparations with respect to the rinsing process ends at at least two different times.

Thus, for example, the delivery of the second active compound preparation for at least 1 s, preferably at least 2 s after the start of delivery of the first drug preparation begin, and / or it lasts for example at least 1 s, preferably at least 2 s longer than the release of the first active ingredient preparation.

There are different types of toilet, with different flushing conditions and flushing times. The device according to the invention is designed for toilet bowl with flushing process in which the rinse water overflows at least one point of the inner wall of the toilet bowl. Thus, the device according to the invention, inter alia for toilet bowl after Standard EN 997 (2003 + A1: 2006) Class 1 suitable.

For the purposes of the invention, the term "equal overflow" above all also presupposes a simultaneous start of overflow. Preferably, the device comprises a rinse water distribution element, such as a distribution plate like EP2310582 known, which is arranged and configured so that the rinse water distribution element is applied during rinsing with rinse water and causes a uniform delivery of the rinse water in all chambers.

The time delay is preferably achieved by a time delay device. In this case, the time delay device is arranged in series within the flushing water flow, which can flow through one of the chambers, in order to influence the flow.

• (i) Auslasslöcher in geringerer Anzahl und/oder mit geringerem Durchmesser im Vergleich zu den anderen Kammern ohne Zeitverzögerungsvorrichtung, so dass der Abfluss aus der Kammer maßgeblich später einsetzt und/oder langsamer verläuft;
• (ii) eine untere Auslassöffnung, die oberhalb eines unteren Bodens der Kammer angeordnet ist, so dass die Kammer zunächst bis zu der Höhe dieser unteren Auslassöffnung voll laufen muss, bevor sie sich entleert;
• (iii) ein in die Kammer hinein stehendes Rohr als Auslass, so dass die Kammer zunächst bis zu der Höhe des inneren Rohrendes voll laufen muss, bevor sie sich entleert;
• (iv) ein Siphon, durch welchen ein Auslöseschwellenniveau und ein Abbruchschwellenniveau für Spülwasser mit wirkstoffhaltiger Lösung in dem Aufnahmebehälter definiert werden, über welche ein Abfließen von Spülwasser mit wirkstoffhaltiger Lösung durch den Siphon beginnen bzw. aufhören kann. Die bevorzugten Varianten für die Zeitverzögerungsvorrichtung werden weiter unten im Detail erläutert.

In a preferred variant of the invention, the time delay device is arranged so that the flow of power out of the chamber is influenced. Examples of the time delay device within a chamber are:

• (i) fewer and / or smaller diameter outlet holes compared to the other chambers without time delay means, so that the outflow from the chamber is significantly later and / or slower;
• (ii) a lower outlet opening located above a lower floor of the chamber so that the chamber first has to fully run to the level of that lower outlet opening before it empties;
• (iii) a tube standing in the chamber as an outlet, so that the chamber must first run to the level of the inner tube end before it empties;
• (iv) a siphon, by which a trigger threshold level and a break threshold level for rinse water with drug-containing solution in the receptacle are defined, via which a drainage of rinse water with drug-containing solution by the siphon can start or stop. The preferred variants for the time delay device will be explained in detail below.

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

In a further embodiment of the invention, the second chamber comprises a time delay device, and the first chamber comprises a further time delay device which has a different time delay than having the time delay device of the second chamber. In another embodiment of the invention, the second chamber includes a time delay device while the first chamber does not have a time delay device. The first preparation of active ingredient from the first chamber is thus discharged from the first chamber into the toilet bowl immediately after the beginning of the overflow of the receptacle. In this case, the time interval between the beginning of the overflow of the receiving container and the discharge from the first chamber is significantly shorter than 1 s, preferably shorter than 0.2 s. Basically, a chamber according to the invention, no time delay device when a defined amount of flushing water can flow out of a chamber substantially equally fast or faster than it flows into the chamber in question.

In a preferred embodiment of the invention, the outlet opening (s) of the second chamber have (s) a smaller overall cross section with respect to the first outlet opening (s) of the first chamber. For example, with the same number of outlet openings in the individual chambers, the individual outlet openings of the first chamber have a larger individual diameter than the outlet openings of the second chamber. Although the first and the second chamber, at the same overflow, at the same time take up rinse water, the rinse water containing active ingredient solution flows out of the second chamber more slowly due to the smaller total cross section of the outlet openings, and thus causes the release of active ingredient preparation from the second chamber via a longer period of time. By this variant can be effected in a very favorable manner, a time delay in the drug delivery in relation to the actual rinsing process.

In a further advantageous embodiment of the invention, the second chamber with time delay device with respect to the other chambers without time delay device outlet openings in a smaller number. Optionally, only a single outlet opening is present in the second chamber. As a result of this smaller number, only a smaller volume of flushing water can flow off at the same time, so that a time delay with respect to the first chamber is effected with more outlet openings.

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

In a particularly preferred embodiment of the invention, the time delay device is a siphon. It has been found that smaller volume chambers fill up flushed with rinse water rather quickly during the rinse and leave little room for adjusting the time delay of the start of the run. On the other hand, it was found that a siphon can be made very flexible, so that even in smaller chambers, the outflow can be delayed a few seconds compared to the beginning of rinsing. A siphon is therefore a preferred time delay device. A siphon is further preferred for chambers with a water collection volume of less than or equal to 50 cm ³ , even more preferably less than or equal to 30 cm ³ . In a preferred variant with a siphon, the siphon comprises a tube and a lid, wherein the lid is attached to the tube.

By a temporally offset release of active ingredient preparations, a targeted delivery of active compound preparations, in particular of different active compound preparations, in the different periods of the rinsing process is possible. This ensures a particularly effective and targeted delivery of individual active ingredients at the best possible time without using a complicated control unit.

In one embodiment of the invention, the first and the second active ingredient preparation contain mutually incompatible ingredients. In the case of simultaneous presence in a preparation, these could, for example, enter into unwanted chemical reactions or lead to phase separation. However, they can also be different dyes whose mixture in a single phase would lead to an altered, undesirable color impression. Examples of ingredients that may be incompatible with each other include bleaches and dyes or fragrances, or proteases and other enzymes. Further examples are well known to those skilled in the art. Due to the temporally staggered delivery both active ingredient preparations can at least partially independently exert their effect.

In another embodiment of the invention, the first active ingredient preparation and the second active ingredient preparation are compatible with one another, but are intended to have their effect at different times, so that they are kept in different chambers of the device. In a preferred development, the first and the second active ingredient preparation contain different active ingredients thereof Drug class, which are chemically different. For example, different surfactants or different enzymes can be used. Furthermore, the first and the second active ingredient preparation may contain the same active ingredients in different concentrations.

In one embodiment of the invention, the second active ingredient preparation comprises at least one active ingredient which is intended to exert its effect mainly after a rinsing process. An example of such an agent is a water-soluble dye that dyes the rinse water, with a blue color being preferred. By a significant after-running even after completion of the rinsing this dye is not washed away, but remains in sufficient concentration in the toilet sump, ie in the toilet bowl remaining rest rinse water contained to give this one, preferably blue, color. Further examples of active ingredients which also or mainly after completion of the rinsing process are fragrances, lime and urinary stone-dissolving ingredients, rinse aids or gloss enhancers, surface treatment agents, e.g. Soil repellent agents or agents for controlling bad odors, disinfectants or bleach, foam boosters.

In another embodiment of the invention, one of the active ingredient preparations comprises an active ingredient which is intended to exert its effect mainly during a rinsing process. For example, a surfactant for foam formation. The rinse operation is used to form foam by mixing surfactant-enriched rinse water and air. This surfactant should essentially be delivered to the rinse water during the rinse to avoid excessive release of surfactant.

Another example is an active ingredient preparation which is intended to clean the toilet bowl by chemical-mechanical cleaning. This must be dispensed during the rinsing process, preferably starting immediately with the beginning of the rinsing process. The flow of the enriched rinse water provides for the mechanical part of the toilet cleaning.

Perfume

At least one of the active compound preparations preferably contains one or more fragrances. These are in the solid, gel or liquid drug preparation, d. H. in the WC block or toilet cleaner, preferably in an amount of 0.01 to 10 wt .-%, in particular 0.05 to 8 wt .-%, particularly preferably 0.1 to 5 wt .-%. As a perfume component, d-limonene may be contained. In a particularly preferred embodiment, the active ingredient preparation contains adherent fragrances, especially essential oils (also referred to as essential oils).

But other adherent fragrances, such as the higher-boiling or solid fragrances of natural or synthetic origin, or more volatile fragrances, especially the lower-boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures, are within the scope of the present invention in Perfume oil advantageously used. It may further be preferred that the agents used in the different chambers contain different fragrances, so that the scent impression changes after completion of the rinsing process. Furthermore, it may also be preferred that the agents used in the different chambers contain the same fragrances, but that differ in their concentration, so that the fragrance is perceived after completion of the rinsing process in a changed intensity.

complexing

INCI chelating agents, also called sequestrants, are ingredients that are capable of complexing and inactivating metal ions to prevent their detrimental effects on the stability or appearance of the agents, such as clouding. On the one hand, it is important to complex the incompatible with numerous ingredients calcium and magnesium ions of water hardness. On the other hand, the complexation of the ions of heavy metals such as iron or copper delays the oxidative decomposition of the finished agents. In addition, the complexing agents support the cleaning effect.

Suitable examples are the following according to INCI complexing agents: Aminotrimethylene Phosphonic Acid, Beta Alanine Diacetic Acid, Calcium Disodium EDTA, Citric Acid, Cyclodextrin, Cyclohexanediamine Tetraacetic Acid, Diammonium Citrate, Diammonium EDTA, Diethylenetriamine Pentamethylene Phosphonic Acid, Dipotassium EDTA, Disodium Azacycloheptane diphosphonates , Disodium EDTA, Disodium Pyrophosphate, EDTA, Etidronic Acid, Galactic Acid, Gluconic Acid, Glucuronic Acid, HEDTA, Hydroxypropyl Cyclodextrin, Methyl Cyclodextrin, Pentapotassium Triphosphate, Pentasodium Aminotrimethylene Phosphonate, Pentasodium Ethylenediamine Tetramethylene Phosphonate, Pentasodium Pentetate, Pentasodium Triphosphate, Pentetic Acid, Phytic Acid, Potassium Citrate, Potassium EDTMP, Potassium Gluconate, Potassium Polyphosphate, Potassium Trisphosphonomethylamine Oxides, Ribonic Acid, Sodium Chitosan Methylene Phosphonate, Sodium Citrate, Sodium Diethylenetriamine Pentamethylene Phosphonate, S orodium dihydroxyethylglycinate, sodium EDTMP, sodium glutamate, sodium gluconate, sodium glycereth-1 polyphosphate, sodium hexametaphosphate, sodium metaphosphate, sodium metasilicate, sodium phytate, sodium polydimethylglycinophenolsulfonate, sodium trimetaphosphate, TEA-EDTA, TEA polyphosphate, tetrahydroxyethyl ethylene diamine, tetrahydroxypropyl ethylene diamine, Tetrapotassium Etidronate, Tetrapotassium Pyrophosphate, Tetrasodium EDTA, Tetrasodium Etidronate, Tetrasodium Pyrophosphate, Tripotassium EDTA, Trisodium Dicarboxymethyl Alaninate, Trisodium EDTA, Trisodium HEDTA, Trisodium NTA and Trisodium Phosphate.

polymers

At least one of the active compound preparations according to the invention may furthermore contain polymers. These can be used, for example, to reduce calcification and the tendency to re-soiling (so-called soil repellent polymers).

Preferred polymers are acrylic polymers, such as those commercially available from Rhodia under the trade name Mirapol.

dyes

Further ingredients which can be used according to the invention comprise one or more dyes (INCI Colorants). As dyes both water-soluble and oil-soluble dyes can be used, on the one hand, the compatibility with other ingredients, such as bleaches, is observed and on the other hand, the dye used against the toilet ceramic should not be substantive even after prolonged exposure. It is preferred if the second active ingredient preparation comprises a water-soluble dye which dyes the rinse water, with a blue color being preferred. The rinse water colored with this dyestuff remains in a sufficient concentration in the toilet sump after the end of the actual rinsing process, ie in the residual rinse water remaining in the toilet bowl in order to give it a, preferably blue, color. The dyes are preferably present in an amount of 0.0001 to 0.1 wt .-%, in particular 0.0005 to 0.05 wt .-%, particularly preferably 0.001 to 0.01 wt .-%, contained.

Furthermore, active ingredients can be used to prevent or reduce bad odors, so-called malodor repellents. These are generally substances which adsorb, complex, oxidise or form inclusion compounds with the volatile substances producing the bad odor, so that they are inactivated in the odor (so-called deodorants) or fragrances with their own odor Cover the disturbing bad smell and neutralize it in this way (so-called odor improver).

Builder

Water-soluble and / or water-insoluble builders may optionally be used in the compositions which can be used according to the invention. Water-soluble builders are preferred because they tend to be less likely to leave insoluble residues on hard surfaces. Typical builders which may be present in the invention are the low molecular weight polycarboxylic acids and their salts, the homopolymeric and copolymeric polycarboxylic acids and their salts, the citric acid and its salts, the carbonates, phosphates and silicates. Water-insoluble builders include the zeolites, which may also be used, as well as mixtures of the aforementioned builders.

bleach

Bleaching agents according to the invention can be added to at least one of the active compound preparations. Suitable bleaching agents include peroxo compounds, in particular peroxides, peracids, percarbonates and / or perborates, particular preference is given to sodium percarbonate, phthalimidoperoxyhexanoic acid or hydrogen peroxide. Alkali metal hypochlorites such as sodium hypochlorite, on the other hand, are less suitable for acidified detergents because of the release of toxic chlorine gas vapors, but can be used in alkaline detergents. Also suitable are trichloroisocyanuric acid and especially sodium dichloroisocyanurate. Under certain circumstances, a bleach activator may be required in addition to the bleaching agent.

corrosion inhibitors

Suitable corrosion inhibitors (INCI Corrosion Inhibitors) are, for example, the following named according to INCI: Cyclohexylamine, Diammonium Phosphate, Dilithium Oxalate, Dimethylamino Methylpropanol, Dipotassium Oxalate, Dipotassium Phosphate, Disodium Phosphate, Disodium Pyrophosphate, Disodium Tetrapropenyl Succinate, Hexoxyethyl Diethylammonium, Phosphates, Nitromethanes, Potassium Silicate, Sodium Aluminate, Sodium Hexametaphosphate, Sodium Metasilicate, Sodium Molybdate, Sodium Nitrites, Sodium Oxalate, Sodium Silicate, Stearamidopropyl Dimethicone, Tetrapotassium Pyrophosphate, Tetrasodium Pyrophosphate, Triisopropanolamine.

Abspülregulatoren

The designated as Abspülregulatoren substances serve primarily to control the consumption of funds during use so that the intended life is met. Suitable regulators are preferably solid long-chain fatty acids, such as stearic acid, but also salts of such fatty acids, fatty acid ethanolamides, such as coconut fatty acid monoethanolamide, or solid polyethylene glycols, such as those having molecular weights between 10,000 and 50,000.

Active ingredients to reduce stickiness

To improve the processability in the production of solid toilet cleaning blocks which can be used according to the invention, in particular those in spherical form, it is possible to add an active ingredient to reduce the stickiness. Thus, the addition of dolomite powder or titanium dioxide powder with a fine particle size distribution improves the processing behavior during spheroidization and significantly reduces abrasion or stickiness. The results with such active ingredients are better than with other conventional measures, for example coating the balls with a lubricant, dusting or coating the forming rollers with Teflon.

enzymes

The agent may also contain enzymes, preferably proteases, lipases, amylases, hydrolases and / or cellulases. They can be added to the agent which can be used according to the invention in any form established according to the prior art. These include solutions of the enzymes, preferably concentrated as possible, low in water and / or added with stabilizers. Alternatively, the enzymes can be encapsulated, for example by spray drying or extrusion of the enzyme solution together with a, preferably natural, polymer or in the form of capsules, for example those in which the enzymes are entrapped as in a solidified gel or in core-shelled form. Type in which an enzyme-containing core is coated with a water, air and / or chemical impermeable protective layer. In deposited layers, further active ingredients, for example stabilizers, emulsifiers, pigments, bleaches or dyes, may additionally be applied. Such capsules are applied by methods known per se, for example by shaking or rolling granulation or in fluid-bed processes. Advantageously, such granules, for example by applying polymeric film-forming agent, low in dust and storage stable due to the coating.

In addition, enzyme stabilizers may be present in enzyme-containing agents in order to protect an enzyme contained in an agent according to the invention from damage such as, for example, inactivation, denaturation or decomposition, for example by physical influences, oxidation or proteolytic cleavage. Suitable enzyme stabilizers, in each case depending on the enzyme used, are in particular: benzamidine hydrochloride, borax, boric acids, boronic acids or their salts or esters, especially derivatives with aromatic groups, for example substituted phenylboronic acids or their salts or esters; Peptide aldehydes (oligopeptides with reduced C-terminus), amino alcohols such as mono-, di-, triethanol- and -propanolamine and mixtures thereof, aliphatic carboxylic acids up to C ₁₂ , such as succinic acid, other dicarboxylic acids or salts of said acids; end-capped fatty acid amide alkoxylates; lower aliphatic alcohols and especially polyols, for example glycerol, ethylene glycol, propylene glycol or sorbitol; and reducing agents and antioxidants such as sodium sulfite and reducing sugars. Other suitable stabilizers are known in the art. Preference is given to using combinations of stabilizers, for example the combination of polyols, boric acid and / or borax, the combination of boric acid or borate, reducing salts and succinic acid or other dicarboxylic acids or the combination of boric acid or borate with polyols or polyamino compounds and with reducing salts.

Multi-layer toilet cleaning blocks

From the prior art, for example EP 791047B1 , It is known to produce substantially solid WC cleaning blocks of different composition masses, wherein one of the masses of the or the other masses is completely or partially enclosed. Thus, for example, the inner mass may have a higher perfume concentration than the outer, to ensure a constant fragrance impression with decreasing ball mass during the service life, or the inner mass contains a different fragrance than the outer. In addition, other active ingredients can be incorporated into different layers, which are released depending on the Abspülgrad at different times. Such a layered structure is also possible in the case of the WC cleaning block which can be used according to the invention.

In one embodiment of the invention, the second active ingredient preparation comprises a surface treatment agent, preferably a soil repellent active ingredient.

In a further embodiment of the invention, the second active ingredient preparation comprises a lime and urinary stone-dissolving ingredient, preferably one or more acids or salts. These can thus develop their effect even after completion of the rinsing process.

In a further embodiment of the invention, the second active ingredient preparation comprises a bleaching agent. This is particularly preferred if an incompatible with bleach active ingredient is present in the first active ingredient preparation, for example an enzyme, a special fragrance, a color, or other organic or polymeric active ingredients.

In a preferred embodiment of the invention, the second active ingredient preparation comprises a water-soluble dye for dyeing the rinse water. This is preferably a blue dye which, after completion of the actual rinsing process, remains in a sufficient concentration in the toilet sump, ie in the residual rinse water remaining in the toilet bowl, and gives it a blue color. In this case, it is furthermore preferred if further active ingredients incompatible with the dye, for example bleaching agents or further water-soluble dyes, are not present in this active compound preparation but are contained in the means reserved in the first (or any further) chamber.

In further embodiments of the invention, the second active ingredient preparation comprises fragrances, rinse aid, substances for increasing the gloss, active substances for combating malodors or foam boosters.

The preferred shape of the WC blocks is rotationally symmetric, in particular spherical, u. a. to set a particularly favorable ratio of volume to surface for the toilet block. This is particularly favorable in a chamber with a time delay device. For example, if the second chamber has a time delay device, in particular a siphon, the chamber remains filled with rinse water at a certain level longer. A spherical WC block consequently has little contact with the rinsing water in the chamber in the lower area and is thus not unnecessarily dissolved.

In one embodiment of the invention, the receptacle comprises at least one wall which separates the first from the second and optionally further chamber. This ensures that the optionally incompatible active ingredient preparations located in the at least one first chamber and the at least one second chamber do not come into contact, as a result of which, for example, undesired reactions can be avoided between the individual preparations of active compound or a color transfer between the chambers.

In a particular embodiment of the invention, the second chamber is designed centrally within the receptacle. For example, the second chamber is enclosed on one side by the first chamber on the other side by a further chamber. Of course, as needed, the formation of additional chambers is also possible.

It is particularly preferred that the first chamber and the second chamber, which form the receptacle, are coupled to each other, more preferably formed in one piece.
