Description

DESCRIPTION

Device for dispensing a preparation of active ingredients into a toilet bowl

The invention relates to a multi-chamber device for the dispensing of active ingredient preparations into a toilet bowl with a housing container, which is to be arranged in the toilet bowl, typically under its rim, which is overflowed during rinsing, in order to the preparation of active ingredients.

For the automatic cleaning of toilet bowls, it is known how to apply lumpy or essentially solid active ingredient preparations ("toilet blocks") into a receptacle-like receiving container on the inner rim of the toilet bowl. With each rinsing process, a part of the active ingredient preparation from a toilet block is dissolved in the rinsing water and distributed together with the rinsing water in the toilet bowl. A device of this type is known, for example, from EP2310582 (A1). Additionally, a smaller part of the active ingredient preparation remains dissolved in the remaining water in the toilet bowl and ensures cleaning there too. However, the amount of active ingredient preparation that remains after the flushing process in the toilet bowl is quite small.

The same problem also exists for devices (toilet sachets) for dispensing liquid active ingredient preparations. A device of this type is known, for example, from EP1334239 B1.

An essential disadvantage of all these toilet bowl sachets is, however, that the dosage of all the possibly different active ingredient preparations present in the receiving container takes place at the same time and during the rinsing process. This has the consequence that active ingredient preparations which should take effect after the start or at least partially after the end of the rinsing process cannot function optimally.

From US 6,662,380 a device is known which remedies this disadvantage by dispensing with a time delay of a dissolved active principle. This device is constructed in a complicated way due to the combination of a liquid active principle with a solid one.

Therefore, the object of the invention is to provide a device, constructed in a simple way, for the dispensing of active ingredient preparations into a toilet bowl, the dispensing of the active ingredient preparations into a toilet bowl taking place at the moment optimum.

This objective is solved by a device with the features of claim 1. Preferred embodiments are described by the dependent claims.

The device according to the invention for dispensing active ingredient preparations into a toilet bowl comprises a receiving container to be arranged in a toilet bowl, the receiving container being able to be fixed to the toilet bowl. The housing container comprises a first chamber and at least one second chamber. The first chamber dispenses a first preparation of active ingredients into the toilet bowl in the event of overflow of rinsing water and the second chamber or additional chamber dispenses a second preparation of active ingredients or a preparation of ingredients in case of overflow of rinse water additional assets in the toilet bowl. The chambers are designed in such a way that at least the first active ingredient preparation and the second active ingredient preparation or additional active ingredient preparation are dispensed both in a time-shifted manner from each other and at least one of the preparations. of active ingredients in a delayed manner compared to the flushing process in the toilet bowl. If more than two chambers are present, the additional chambers may again contain the first, second or additional active ingredient preparation, which at other times or preferably at the same time are dispensed into the toilet bowl as well as the corresponding preparations of the first or second chamber. However, they can also contain one or more additional active ingredient preparations, which can be dispensed, in turn, either at the same time with one of the other preparations, or alternatively in a time-shifted manner in the cup. toilet.

In the sense of this invention, a "preparation of active ingredients" is understood to mean a solid preparation that dissolves by it when it comes into contact with rinse water and can then be dispensed as a solution containing active ingredients, that is, a mixture of rinse water. and active ingredients, in the toilet bowl. Such a solution containing active ingredients can be originated, for example, also by overflowing a solid toilet cleaning block by the rinsing water in the housing container and can then be dispensed into the toilet bowl.

The time shift enables the targeted dispensing of the same or different active ingredient preparations at different times in the toilet bowl. A typical rinsing process inside a typical toilet bowl has two characteristic moments, namely the beginning of the rinse and the end of the rinse. These moments define the time interval: before the rinsing process, during the rinsing process, and after the rinsing process. The first and second active ingredient preparations are different. Since the different active ingredient preparations can have different functions, it is often reasonable that different active ingredient preparations are dispensed at different times during the rinsing process to fulfill these functions optimally. Such an optimized dispensing saves on active ingredient preparation and achieves the best performance.

The device according to the invention, which does not have an additional mechanism, for example electrical, has an autonomous active ingredient dispensing, can dispense the active ingredient preparation at the beginning of the rinsing process, from the first chamber in the rinse water and therefore in the toilet bowl. The rinse water overflows, among other things, the first chamber and enters through an inlet into the first chamber, overflows the first active ingredient preparation and flows as a solution containing active ingredients enriched with the first ingredient preparation. active through an outlet out of the first chamber in the direction of the toilet bowl. In an analogous manner, the second active ingredient preparation reaches the toilet bowl from the second chamber, dispensing is carried out, however, in a time-shifted manner.

The first and second chambers are designed in such a way that, in the event of the same overflow, the first active ingredient preparation and the second active ingredient preparation are dispensed in a time-shifted manner from each other into the toilet bowl. The time-shifted dispensing of the active ingredient preparation into the toilet bowl means in the sense of the invention that:

i) uses the dispensing of the at least two different active ingredient preparations with respect to the rinsing process at at least two different times and / or

ii) the dispensing of the at least two different active ingredient preparations with respect to the rinsing process ends at at least two different times.

Thus, for example, the dispensing of the second active ingredient preparation can begin at least 1 s, preferably at least 2 s after the start of the dispensing of the first active ingredient preparation, and / or lasts for example at least 1 s, preferably at least 2 s longer than the dispensing of the first active ingredient preparation.

There are different types of toilets, with different rinsing behaviors and rinsing times. The device according to the invention is designed for toilet bowls with a rinsing process in which the rinsing water floods at least one point of the internal wall of the toilet bowl. Thus, the device according to the invention is suitable, inter alia, for toilet bowls according to EN 997 (2003 + A1: 2006) class 1.

The term "same overflow" in the sense of the invention also presupposes, in particular, a beginning of the simultaneous overflow. Preferably, the device comprises a rinse water distribution element, for example a distribution plate such as that known from EP2310582, which is arranged and configured in such a way that the rinse water distribution element is pressurized during rinse with rinse water and causes a uniform dispensing of rinse water in all chambers.

The time delay is achieved by a timing device configured as a siphon. In this regard, the timing device within the rinse water stream, which can flow through one of the chambers, is arranged in series to influence the flow.

The siphon defines an activation threshold level and a termination threshold level for rinse water with solution containing active ingredients in the housing container, through which an outflow of rinse water can start or stop with solution containing active ingredients through the siphon. Preferred variants for the timing device are explained in detail below.

According to the invention, at least the second chamber comprises the timing device configured as a siphon.

In a further design of the invention, the second chamber comprises a timing device configured as a siphon, and the first chamber an additional timing device having a different time delay than the timing device of the second chamber.

In another design of the invention, the second chamber comprises a timing device, while the first chamber does not have a timing device. The first active ingredient preparation from the first chamber is therefore dispensed just after the start of the overflow from the receiving container of the first chamber into the toilet bowl. In this case, the time interval between the start of the overflow of the receiving container and the dispensing of the first chamber is clearly shorter than 1 s, preferably shorter than 0.2 s. In principle, a chamber in the sense of the invention does not have any timing device, when a defined quantity of rinsing water can flow out of a chamber essentially as fast or faster than that which flows into the chamber. camera in question.

According to the invention, the outlet opening (s) of the second chamber in relation to the first outlet opening (s) of the first chamber has / are a smaller total cross-section. For example, in the case of the same number of outlet openings in the individual chambers, the individual outlet openings in the first chamber have a larger individual diameter than the outlet openings in the second chamber. Although the first and second chambers, in the event of the same overflow, absorb rinsing water at the same time, the rinsing water flows with a solution containing active ingredients due to the smaller total cross-section of the outlet openings more slowly towards outside the second chamber, and therefore causes the dispensing of active ingredient preparation from the second chamber to take place over a longer period of time. By means of this variant, a delay in time in the dispensing of active ingredients can be very favorably caused in relation to the rinsing process itself.

In a further advantageous design of the invention, the second chamber with a timing device relative to the other chambers without a timing device has fewer outlet openings. If necessary, only a single outlet opening is present in the second chamber. By means of this smaller number, only a smaller volume of rinsing water can flow out at the same time, so that a time delay is caused with respect to the first chamber with more outlet openings.

According to the invention, the timing device is a siphon. It was found that the chambers with a smaller volume during the rinsing process fill with rinsing water rather quickly, and allow little adjustment possibilities for the regulation of the delay in the time of the start of the discharge. On the other hand, it was found that a siphon can be designed in a very flexible way so that even in smaller chambers the outflow can be delayed by a few seconds with respect to the start of the rinse. A siphon is furthermore preferred for chambers with a water collection volume less than or equal to 50 cm3, even more preferably less than or equal to 30 cm3. In a preferred variant with a siphon, the siphon comprises a tube and a cap, the cap being fitted onto the tube.

By means of a dispensing of active substance preparations offset in time from one another, a targeted dispensing of active substance preparations, in particular of different active substance preparations, is possible at different time periods of the rinsing process. This ensures a particularly effective and targeted dispensing of individual active ingredients at the best possible time without using a complicated control unit.

In one design of the invention, the first and second active ingredient preparations contain mutually compatible ingredients. These could, for example, cause undesired chemical reactions with each other in case of simultaneous presence in a preparation or lead to phase separation. However, it can also be different colorants, the mixture of which would be conducted in a single phase until giving a modified and unwanted color impression. Examples of ingredients that can be compatible with each other are for example bleaching and coloring agents or fragrances, or also proteases and other enzymes. Other examples are well known to the person skilled in the art. Due to the dispensing displaced from each other in time, both active substance preparations can at least partially display their effect independently of each other.

In another design of the invention, the first active ingredient preparation and the second active ingredient preparation are compatible with each other, although they must display their effect at different times, so that they are maintained in different chambers of the device. In a preferred development, the first and second active compound preparations contain different active compounds from the same active compound class, which are nevertheless chemically different. Thus, for example, different surfactants or different enzymes can be used. Furthermore, the first and second active ingredient preparations can contain the same active ingredients in different concentrations.

In one design of the invention, the second active ingredient preparation comprises at least one active ingredient, which must develop its effect mainly after a rinsing process. An example of such an active principle is a water-soluble dye, which dyes the rinse water, a blue color being preferred. Due to a clear subsequent operation, even after the rinsing process has finished, this colorant does not continue to be rinsed, but remains in a sufficient concentration in the toilet drain, that is, in the remaining rinse water. in the toilet bowl, to give this color, preferably blue. Other examples of active principles, which develop their effect also or mainly after the completion of the rinsing process, are aromatic substances, limescale and urine deposit solvent ingredients, brighteners or substances to increase shine, surface treatment agents such as for example soil-repellent active ingredients or also active ingredients to combat bad odors, disinfecting or bleaching agents, foam enhancers.

In another design of the invention, one of the active ingredient preparations comprises an active ingredient, which must display its effect mainly during a rinsing process. For example, a surfactant for foaming. The rinse process is used to form by mixing surfactant-enriched rinse water and air foam. This surfactant must be dispensed essentially during the rinsing process by rinse water to avoid excessive dispensing of surfactant active ingredient.

A further example is an active ingredient preparation that you must clean the toilet bowl by means of a chemical-mechanical cleaning. This has to be dispensed during the rinsing process, preferably starting right with the beginning of the rinsing process. The enriched rinse water flow provides the mechanical part of toilet cleaning.

Fragrance

Preferably, at least one of the active ingredient preparations contains one or more aromatic substances. These are contained in the solid, gel or liquid active ingredient preparation, i.e. in the toilet block or toilet bowl cleaner, preferably in an amount of 0.01 to 10% by weight, in particular 0 0.05 to 8% by weight, particularly preferably 0.1 to 5% by weight. As a perfume component, d-limonene can be contained in this connection. In a particularly preferred embodiment, the active compound preparation contains adherent fragrances, in particular ethereal oils (also known as essential oils). As such, for example, pine, citrus, jasmine, patchouli, rose or ylang-ylang oil can be used in the sense of this invention. Also suitable are esclarea essence, chamomile essence, lavender oil, clove essence, lemon balm essence, peppermint oil, cinnamon leaf essence, linden flower essence, juniper berry essence, vetiver essence, essence of frankincense, galbanum essence and labdanum essence as well as orange blossom oil, neroli essence, orange peel oil and sandalwood essence. However, also other adherent fragrances, for example, higher boiling or solid fragrances of natural or synthetic origin, or also more volatile fragrances, in particular lower boiling fragrances of natural or synthetic origin, which can be used alone or in mixtures, they can be used advantageously within the framework of the present invention in perfume oil. It may be further preferred that the media used in the different chambers contain different aromatic substances, so that the aroma impression is modified after the completion of the rinsing process. In addition, it may also be preferred that the media used in the different chambers contain the same aromatic substances, which differ, however, in their concentration, so that the aroma after the end of the rinsing process is perceived in a different intensity .

The terms disinfection, sanitation, antimicrobial action and antimicrobial active ingredients have the usual meaning in the context of teaching according to the invention. While disinfection in the strictest sense of medical practice means the killing of - theoretically all - infectious germs, by sanitation it should be understood the elimination as far as possible of all germs, including saprophytes that are normally harmless for humans. In this case, the degree of disinfection or sanitation depends on the antimicrobial action of the applied agent, which decreases as the content of the antimicrobial active principle decreases or as the dilution of the agent for its application increases.

Suitable according to the invention are, for example, antimicrobial active ingredients from the groups of alcohols, aldehydes, antimicrobial acids or their salts, carboxylic acid esters, acid amides, phenols, phenol derivatives, diphenyls, diphenylalkanes, derivatives of urea, oxygen-, nitrogen-acetals and -formals, benzamidines, isothiazoles and their derivatives such as isothiazolines and isothiazolinones, phthalimide derivatives, pyridine derivatives, antimicrobial compounds with surface activity, guanidines, amphoteric antimicrobial compounds, quinolines, 1,2-dibrom-2,4-dicyanobutane, iodo-2-propynyl-butyl-carbamate, iodine, iodophors, active chlorine releasing compounds and peroxides. Preferred antimicrobial active ingredients are preferably selected from the group comprising ethanol, n-propanol, i-propanol, 1,3-butanediol, phenoxyethanol, 1,2-propylene glycol, glycerol, undecylenic acid, citric acid, lactic acid, benzoic acid , salicylic acid, thymol, 2-benzyl-4-chlorophenol, 2,2'-methylene-bis- (6-bromo-4-chlorophenol), 2,4,4'-trichloro-2'-hydroxydiphenyl ether, N - (4-chlorophenyl) -N- (3,4-dichlorophenyl) -urea, N, N '- (1,10-decandiyldi-1-pyridinyl-4-ylidene) -bis- (1-octaamine) dihydrochloride, N, N'-bis- (4-chlorophenyl) -3,12-diimino-2,4,11,13-tetraazatetradecandiimidamide, quaternary antimicrobial surface active compounds, guanidine and sodium dichloroisocyanurate (INN, sodium salt of 1,3 -dichloro-5H-1,3,5-triazine-2,4,6-trione). Quaternary compounds with preferred antimicrobial surface activity contain an ammonium, sulfonium, phosphonium, iodonium or arsonium group. Furthermore, etheric oils with antimicrobial action can also be used, which at the same time ensure an odorization of the cleaning agent. However, especially preferred antimicrobial active ingredients are selected from the group comprising salicylic acids, quaternary surfactants, in particular benzalkonium chloride, peroxo compounds, in particular sodium percarbonate, phthalimidoperoxyhexanoic acid or hydrogen peroxide, alkali metal hypochlorite, trichloroisocyanuric acid , sodium dichloroisocyanurate as well as mixtures thereof. Sodium dichloroisocyanurate is very particularly preferred in this case.

Preservatives

Preservatives may be contained in active ingredient preparations according to the invention. As such, essentially the substances mentioned in the antimicrobial active ingredients can be used.

Complexing agents

Complexing agents ( INCI Chelating Agents), also called sequestering agents, are ingredients capable of complexing and inactivating metal ions to prevent their disadvantageous effects on the stability or appearance of the agents, for example turbidity. On the one hand, it is important in this regard to complex the calcium and magnesium ions from the water hardness, which are incompatible with many ingredients. Complexation of heavy metal ions such as iron or copper delays, on the other hand, the oxidative decomposition of the finished agents. In addition, the complexing agents favor the cleaning effect.

Suitable for example are the following complexing agents named according to INCI: Aminotrimethylene Phosphonic Acid, Beta-Alanine Diacetic Acid, Calcium Disodium EDTA, Citric Acid, Cyclodextrin, Cyclohexanediamine Tetraacetic Acid, Diammonium Citrate, Diammonium EDTA, Diethylenetriamine Pentameidthylene, Dipotassium EDTA, Disodium Azacycloheptane Diphosphonate, Disodium EDTA, Disodium Pyrophosphate, EDTA, Etidronic Acid, Galactaric Acid, Gluconic Acid, Glucuronic Acid, HEDTA, Hydroxypropyl Cyclodextrin, Methyl Cyclodextrin, Pentanedium Pyrophosphate, Pentanediumsodium Phassium Triphostate, Pentamethylenesodiumstate, Pentathylene Triphostate, Ethylene Phostate, Ethylenesodium Phassium Triphostate, Pentathylensodiumstate, Ethylene Phostate Triphostate, Ethylenesodiumstate Pentasodium Triphosphate, Pentetic Acid, Phytic Acid, Potassium Citrate, Potassium EDTMP, Potassium Gluconate, Potassium Polyphosphate, Potassium Trisphosphonomethylamine Oxide, Ribonic Acid, Sodium Chitosan Methylene Phosphonate, Sodium Citrate, Sodium Diethylenetriamine Pentamethylene Ph osphonate, Sodium Dihydroxyethylglycinate, Sodium EDTMP, Sodium Gluceptate, Sodium Gluconate, Sodium Glycereth-1 Polyphosphate, Sodium Hexametaphosphate, Sodium Metaphosphate, Sodium Metasilicate, Sodium Phytate, Sodium-Polyethylroxy-tetraphonate-TEA, Sodiumydimethylroxy-tetraphonate, Sodium-ethosulfonate-Tenedium-hydroxy-tetraphosphate, Sodium-hydroxy-tetrapyl-ethosulfonate, Sodium-ethosulfonate-tetrapropyl-ethosphophate, Sodium-hydroxy-tetrapropyl-ethosphate, Sodium-ethosulfonate-Tethyl-Ephonate Ethylenediamine, Tetrapotassium Etidronate, Tetrapotassium Pyrophosphate, Tetrasodium EDTA, Tetrasodium Etidronate, Tetrasodium Pyrophosphate, Tripotassium EDTA, Trisodium Dicarboxymethyl Alaninate, Trisodium EDTA, T risodium HEDTA, T risodium NTA and T risodium Phosphate.

Polymers

At least one of the active ingredient preparations according to the invention may also contain polymers. These can be used for example to reduce limescale formation as well as the tendency to dry out (so-called soil repellent polymers).

Preferred polymers are, in this regard, acrylic polymers, such as are commercially available for example from the company Rhodia under the trade name Mirapol.

Colorants

As additional ingredients, the agent that can be used according to the invention may contain one or more colorants ( INCI Colorants). As colorants, both water-soluble and oil-soluble colorants can be used in this regard, taking into account, on the one hand, the compatibility with other ingredients, for example bleaching agents, and, on the other hand, not having the Stain used a substantive effect with respect to toilet ceramic, even in case of prolonged effect. It is preferred that the second active ingredient preparation comprises a water-soluble dye, which dyes the rinse water, a blue color being preferred. The rinse water stained with this colorant remains in sufficient concentration in the toilet drain due to to the operation after the end of the rinsing process itself, that is, in the rest of the rinsing water that remains in the toilet bowl, to impart this color, preferably blue. The colorants are preferably present in an amount of 0.0001 to 0.1% by weight, in particular 0.0005 to 0.05% by weight, particularly preferably 0.001 to 0.01% by weight.

In addition, active principles can be used to prevent or reduce bad smells, the so-called bad smell repellents or malodor repellents. In this case, they are, as a general rule, substances that adsorb, complex, oxidize the volatile substances that generate the bad smell or form inclusion compounds with them, so that they are inactivated in terms of odor (so-called deodorants), or if not fragrances that cover the unpleasant odor with their own smell and neutralize it in this way (the so-called odor enhancers).

Support substances

Water-soluble and / or water-insoluble carrier substances can optionally be used in the agents which can be used according to the invention. In this regard, water-soluble carrier substances are preferred, since they are generally less prone to leaving insoluble residues on hard surfaces. Common carrier substances that may be present within the framework of the invention are low molecular weight polycarboxylic acids and their salts, homopolymeric and copolymeric polycarboxylic acids and their salts, citric acid and its salts, carbonates, phosphates and silicates. The water-insoluble carrier substances include zeolites, which can also be used, as well as mixtures of the carrier substances mentioned above.

Bleaching agents

According to the invention, bleaching agents can be added to at least one of the active ingredient preparations. Suitable bleaching agents comprise peroxo compounds, in particular peroxides, peracids, percarbonates and / or perborates, sodium percarbonate, phthalimidoperoxyhexanoic acid or hydrogen peroxide are especially preferred. Alkali metal hypochlorites, such as sodium hypochlorite, on the other hand, are less suitable for acid-formulated cleaning agents due to the release of toxic chlorine gas vapors, although they can be used in alkaline setting cleaning agents. Also suitable are trichloroisocyanuric acid and in particular sodium dichloroisocyanurate. In certain circumstances, a bleach activator may also be required in addition to the bleaching agent.

Corrosion inhibitors

Suitable corrosion inhibitors ( INCI Corrosion Inhibitors) are, for example, the following substances named according to INCI: Cyclohexylamine, Diammonium Phosphate, Dilithium Oxalate, Dimethylamino Methylpropanol, Dipotassium Oxalate, Dipotassium Phosphate, Disodium Phosphate, Disodium Pyrophosteprophate, Disodium Pyrocinaphosteprophate , Hexoxyethyl Diethylammonium, Phosphate, Nitromethane, Potassium Silicate, Sodium Aluminate, Sodium Hexametaphosphate, Sodium Metasilicate, Sodium Molybdate, Sodium Nitrite, Sodium Oxalate, Sodium Silicate, Stearamidopropyl Dimethiconetrash, Pyramidisophosylamine, Tetrapotrophosphate, Tri-potassium-hydrochloride, Tetrapotrophosine, Tetrapotrophosphate, Tri-potassium-hydrochloride, Tetrapotrophosphate

Rinse regulators

Substances called rinse regulators serve primarily to control the consumption of agents during use in such a way as to maintain the expected shelf life. 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 of molecular weights between 10,000 and 50,000.

Active ingredients to reduce stickiness

To improve processability in the production of solid toilet cleaning blocks that can be used according to the invention, in particular those of spherical shape, an active ingredient can be added to decrease tack. Thus, the addition of dolomite powder or titanium dioxide powder with a fine particle size distribution improves the processing behavior in the case of spherical shapes and clearly reduces abrasion or stickiness. The results with such active ingredients are better than with other usual measures, for example coating the spheres with a slip agent, spraying or coating the casting rolls with Teflon.

Enzymes

The agent may also contain enzymes, preferably proteases, lipases, amylases, hydrolases and / or cellulases. They can be added to the agent that can be used according to the invention in any way established according to the state of the art. These include solutions of the enzymes, advantageously as concentrated as possible, with little water and / or mixed with stabilizers. Alternatively the enzymes can be encapsulated, for example by spray drying or extrusion of the enzyme solution together with a polymer, preferably natural, or in the form of capsules, for example, those in which the enzymes are enclosed as in a solidified gel, or in those of the type core-shell, in which an enzyme-containing core is coated with a protective layer impermeable to water, air and / or chemicals. Other active substances, for example stabilizers, emulsifiers, pigments, bleaching substances or colorants, can additionally be applied in superposed layers. Capsules of this type are applied by methods known per se, for example by stirring or rolling granulation or in fluidized bed processes. Advantageously, granules of this type, for example by applying polymeric film formers, are poor in dust and, due to the coating, stable on storage.

Furthermore, they may be present in enzyme-stabilizing agents containing enzymes 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 are, in each case depending on the enzyme used, 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; peptidaldehydes (oligopeptides with reduced C-termination), amino alcohols such as mono-, di-, triethanol- and -propanolamine and their mixtures, aliphatic carboxylic acids up to C ¹² , such as succinic acid, other dicarboxylic acids or salts of the mentioned acids; end-group protected fatty acid amidalkoxylates; lower aliphatic alcohols and especially polyols, for example glycerin, ethylene glycol, propylene glycol or sorbitol; as well as reducing agents and antioxidants such as reducing sodium sulfite and sugar. Other suitable stabilizers are known from the state of the art. Combinations of stabilizers are preferably used, 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 compounds of polyamine and with reducing salts.

Multilayer Toilet Cleaning Blocks

From the state of the art, for example EP 791047B1, it is known how to produce essentially solid toilet cleaning blocks from masses of different composition, one of the masses being completely or partially surrounded by one or the other mass. Thus, for example, the internal mass may have a higher concentration of perfume than the external to guarantee a constant impression of the aroma during the useful life as the mass of the sphere decreases, or else the internal mass contains an aromatic substance other than the outside. In addition, other active ingredients can also be incorporated in different layers, which are released depending on the degree of rinsing at different times. Such a layer-like construction is also possible in the toilet cleaning block that can be used according to the invention.

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

In a further design of the invention, the second active ingredient preparation comprises a lime solvent ingredient and urine deposit, preferably one or more acids or salts. These can thus develop their effect also after the rinsing process has been completed.

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

In a preferred design of the invention, the second preparation of active ingredients comprises a water-soluble dye for coloring the rinse water. In this case it is preferably a blue color, which remains after the completion of the rinsing process itself in a sufficient concentration in the toilet drain, that is, in the rest of the rinsing water that remains in the toilet bowl, and gives it a blue color. In this case, it is furthermore preferable that additional active ingredients incompatible with the colorant, for example bleaching agents or other water-soluble colorants, are not present in this active ingredient preparation, but rather are contained in the medium stored in the first chamber ( or an additional camera present if necessary).

In other designs of the invention, the second preparation of active principles comprises aromatic substances, brighteners, substances to increase shine, active principles to combat bad odors or also foam enhancers.

According to the invention, the first and second active substance preparations are present as solid bodies in the receiving container, as geometrically shaped toilet blocks of any choice (also called toilet bars). The preferred conformation of the toilet blocks is in this respect rotationally symmetrical, in particular spherical, inter alia to set a volume ratio with with regard to particularly favorable surface for the toilet block. This is particularly favorable in a camera with a timing device. For example, when the second chamber has a timing device, in particular a siphon, the chamber remains for a longer time with rinsing water at a certain level. As a consequence, a spherical toilet block has low contact with the rinsing water in the chamber in the lower area and therefore does not dissolve unnecessarily.

In a design of the invention, the receiving container comprises at least one wall, which separates the first from the second chamber, as well as possibly an additional chamber. This ensures that the active ingredient preparations, which may be incompatible, which are in the at least one first chamber and the at least one second chamber, do not come into contact, so that, for example, undesired reactions between individual active ingredient preparations or also color transmissions between the chambers.

In a special design of the invention, the second chamber is realized in the center inside the housing container. For example, the second chamber is enclosed on one side by the first chamber and on the other side by an additional chamber. It is of course also possible depending on the need in a complementary manner also to configure additional cameras.

It is especially preferred that the first chamber and the second chamber, which form the receiving container, are coupled to each other, more preferably that they are configured in one piece.

The housing container is retained by the support in the toilet bowl, so that the latter is positioned in use with the chambers below the support. The support is preferably designed as a suspended support, for example in the form of a hanger.

Furthermore, the housing container is preferably made from plastic, such as for example PET or PP. It is also preferred that the housing container has a transparent design to ensure a view into the chambers filled with active ingredient preparation. In a further development of the invention, the receiving container is transparent or translucent and has a color, preferably blue.

Preferably, the first, second chambers and, if present, the additional chamber in each case are not further subdivided. This is especially preferred when the chambers are respectively designed to fit the geometry of a toilet bar. This results in a very compact design.

Realization example:

Solid and water-soluble active toilet ingredient preparations (so-called toilet cleaning blocks or toilet bars) were formulated according to the framework recipes reproduced in the following table. E1 and E2 comprise, in this regard, in each case two different compositions, one of which must release its active principle with a delay in time. The quantity indications are in this respect in% by weight of the active principle, relative to the respective toilet block.

continuation

In a device according to Figure 2 the block marked "blue" of E1 or E2 was placed in the second chamber and the block marked "yellow" or "white" in the first chamber. The "blue" block in each case contained a water soluble blue dye. In E1, the yellow block contained lathering surfactants; at E2, the white block further comprised the bleaching agent sodium isocyanurate. The devices according to E1 and E2 were suspended in each case from a toilet bowl according to EN 997 (2003 + A1: 2006) class 1 with a rinsing volume of 8-10 L. When rinsing it was observed that at the beginning After the rinsing process, foam formed in the toilet bowl, and that 1 s after the start of the rinsing, rinsing water colored blue with a solution containing active ingredients began to flow out of the second chamber. At the end of the rinse, the dispensing of rinsing water with solution containing active ingredients from the chamber also stopped, while the dispensing of rinsing water with solution containing active ingredients from the second chamber continued for about 4-6 sec. therefore, it dyed the remaining water in the toilet bowl blue.
