Description

Device for dispensing an active ingredient preparation in a toilet bowl

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, active ingredient preparations in lumpy or substantially solid form ("WC blocks") in a cage-like receptacle on

Inner edge of the toilet bowl to install. With each flushing process, part of the

Active ingredient preparation of a toilet block in the rinse water and is distributed together with the rinse water in the toilet bowl. Such a device is e.g. from EP2310582 (A1). 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 known for example from EP1334239 B1.

A major disadvantage of all these toilet bowls is therefore that the dosage of all in the

Receptacle existing possibly different drug formulations substantially simultaneously and during the flushing process runs. 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 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 as an active ingredient-containing solution, d. 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 ingredient preparations are preferably different. Since different preparations of active ingredients may have different functions, it is often useful that different

Active ingredient preparations are delivered at different times in the course of the rinsing process in order to optimally fulfill these functions. Such optimized dispensing saves

Preparation of the active ingredient 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 at the earliest with the beginning of the Flushing the drug preparation, leave the first chamber in the rinse water and thus in the toilet bowl. 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 one arrives

Preparation of active ingredient from the second chamber in the toilet bowl, but the delivery is delayed.

The first and the second chambers are designed so that at the same overflow, the first active ingredient preparation and the second active ingredient preparation offset from one another in the

Toilet bowl are dispensed. 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, in which the rinse water overflows at least one point of the inner wall of the toilet tank. Thus, the device according to the invention is suitable, inter alia, for toilet bowls according to standard EN 997 (2003 + A1: 2006) Class 1.

For the purposes of the invention, the term "equal overflow" primarily also presupposes a simultaneous start of overflowing. <br/> The device preferably comprises a flushing water distribution element, eg a distribution plate as known from EP 2310582, which is arranged and configured such that the flushing water distribution element is flushed with rinsing water during the flushing 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.

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 devices 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, a further time delay device having a different time delay than the time delay device of the second chamber.

In another embodiment of the invention, the second chamber comprises a

Time delay device, while the first chamber has no 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 a smaller one relative to the first outlet opening (s) of the first chamber

Total cross section. 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 rinsing water with active substance 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 over the other chambers without time delay device outlet openings in a smaller number on. 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 bleaching agents and dyes or fragrances, or proteases and other enzymes. Further examples are well known to those skilled in the art. By staggered delivery both can

Active ingredient preparations at least partially independent of each other unfold 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 second active ingredient formulations contain different active ingredients of the same class of active ingredients, 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 basin remaining residual rinse water contained to give this one, preferably blue, color. Further examples of active substances which have their effect also or mainly after completion of the rinsing process are fragrances, lime and urinary stone-dissolving ingredients, rinse aid or substances for increasing the gloss, Surface treatment agents such as 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 is intended to be delivered to the rinse water substantially during the rinse to avoid over-delivery of

Surfactant to avoid.

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 WC 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). Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil, for example, can be used as such in the context of this invention. Also suitable are Muskateller sage oil, chamomile oil, lavender oil, clove oil, balm oil, mint oil, cinnamon oil, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil and labdanum oil and orange blossom oil, neroliol, orange peel oil and sandalwood oil. 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 also be preferred that in the different chambers

used agents contain different fragrances, so that the scent impression after

Completion of the rinse process changes. Furthermore, it may also be preferred that the agents used in the different chambers contain the same fragrances, but in their Concentration differ so that the fragrance is perceived after completion of the rinse in a modified intensity.

The terms disinfection, sanitation, antimicrobial action and antimicrobial agent have the usual meaning within the scope of the teaching according to the invention. While disinfection in the narrower sense of the medical practice means the killing of - in theory all - infectious germs, sanitation is to be understood as the greatest possible elimination of all - including the saprophytic - normally harmless to humans saprophytic - germs. Here, the extent of disinfection or sanitation depends on the antimicrobial effect of the applied agent, which decreases with decreasing content of antimicrobial agent or increasing dilution of the agent for use.

For example, antimicrobial agents from the groups of alcohols, aldehydes, antimicrobial acids or their salts, carboxylic esters, acid amides, phenols, phenol derivatives, diphenyls, diphenylalkanes, urea derivatives, oxygen, nitrogen acetals and formals, benzamidines, isothiazoles and their derivatives are suitable according to the invention Derivatives such as isothiazolines and isothiazolinones, phthalimide derivatives, pyridine derivatives, antimicrobial surface-active compounds, guanidines, antimicrobial amphoteric compounds, quinolines, 1, 2-dibromo-2,4-dicyanobutane, iodo-2-propynyl-butyl-carbamate, iodine, iodophores, active chlorine-releasing Compounds and peroxides.

Hydrogen peroxide, alkali metal hypochlorite, trichloroisocyanuric acid, sodium dichloroisocyanurate and mixtures thereof. Very particular preference is given here to sodium dichloroisocyanurate.

preservatives

Preservatives may also be included in the active compound preparations according to the invention. As such, essentially the substances mentioned in the antimicrobial agents can be used.

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 designated complexing agent:

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 Pyrophosphates, EDTA, Etidronic Acid, Galactic Acid, Gluconic Acid, Glucuronic Acid, HEDTA, Hydroxypropyl Cyclodextrin, Methyl Cyclodextrin,

Resistant to soiling (so-called Soil Repellent polymers) serve.

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 act substantively even with 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, that is, in the residual rinse water remaining in the toilet bowl to give this one, 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.

Active ingredients to reduce stickiness

To improve the processability in the preparation 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 substance for reducing 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 agents 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.

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 those of the core-shell 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 C12, 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; such as

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.
