Abstract

The invention relates to a cleaning agent which contains in a packaging means at least one enzyme-containing and at least one builder-containing preparation separated from one another, as well as a clear-rinsing preparation.

Description

"Detergent with rinse aid for automatic dosing unit"

The invention relates to a cleaning agent which contains, separately from one another, at least one enzyme-containing and at least one builder-containing preparation in a packaging means, as well as a rinse aid preparation.

The manufacturing and supply forms of cleaning agents are always subject to new ones

Changes. For some time now, the main focus has been on the convenient dosing of cleaning agents and the simplification of the work steps required to carry out a cleaning process.

In particular, devices for multiple dosing of cleaning agents are from

Consumers wanted. Devices can be differentiated between metering containers integrated in the dishwasher on the one hand and independent devices independent of the dishwasher on the other. By means of these devices, the multiple of those necessary for carrying out a cleaning process

Containing amount of detergent, detergent portions are metered into the interior of the cleaning machine in an automatic or semi-automatic manner in the course of several successive cleaning processes. For the consumer, this eliminates the need to dose the detergent before the start of each individual cleaning cycle. Examples of such devices are described in European patent application EP 1 759 624 A2 (Reckitt Benckiser) or in German patent application DE 10 2005 062 479 A1 (BSH Bosch and Siemens Hausgeräte GmbH).

In particular, consumers with a low washing / washing volume want a solution that is uncomplicated and easy to use.

Regardless of the exact design of the dosing devices used in the interior of dishwashers, the devices for multiple dosing are contained in these devices

Detergents also changing over a long period of time in particular

Exposed to temperatures, these temperatures being the first approximation of the water temperatures used to carry out the cleaning processes. These temperatures can be up to 95 ° C, with usually only temperatures between 50 and 75 ° C being achieved in the area of machine dishwashing. A cleaning agent contained in a device provided for multiple dosing is accordingly repeatedly heated in the course of several cleaning processes to temperatures significantly above the temperatures customary for transport and storage, in particular temperature-sensitive ones

Active substances are affected. In particular, consumers who load the dishwasher with dishes for several days and for whom the dirty dishes are uncleaned for some time inside the

Dishwasher remains before a rinse cycle is carried out, have the problem that the cleaning performance of the products, especially for stubborn ones, in particular

dried-on food residues on the dishes, for example oatmeal or tea, in the

Compared to prompt rinsing after using the wash items leaves something to be desired. Rinsing off food waste before sorting it into the dishwasher is not advantageous for ecological and time reasons and with regard to the additional water costs.

The object of the present application was therefore to provide a

Form of detergent which provides good cleaning performance, in particular on dried-on food residues, in particular minced meat, oatmeal and / or tea, even if there are several days between the individual usage cycles. This system is said to be particularly inexpensive for the consumer.

A first subject of the present application is therefore a cleaning agent supply form, comprising

a) a liquid (20 ° C) detergent preparation A containing

a1) builders;

a2) complexing agent

b) a liquid (20 ° C) different from the detergent preparation A.

Detergent preparation B with a water content above 1% by weight, containing b1) at least 5% by weight of at least one cleaning-active enzyme preparation c) a liquid (20 ° C.) detergent preparation C,

containing

c1) an acidifying agent,

c2) a glass corrosion inhibitor,

c3) optionally a nonionic surfactant,

c4) optionally a hydrotrope, and

c5) optionally less than 1% by weight, preferably less than 0.5% by weight, in particular less than 0.1% by weight of enzyme preparation, and

d) a packaging material in which the cleaning agent preparations A, B and C are present separately from one another.

The combination of such a composition with the invention

Cleaning agent preparations have the advantage for the consumer that he is concerned with the

Renewal or the replacement of the active ingredient composition and the detergent preparations does not have to worry a lot. He exchanges the combination together and does not have to worry about replacing individual products separately. In particular, he needs do not worry about an additional dosage of rinse aid in the rinse aid chamber of the dishwasher.

The subject of this application are corresponding forms of detergent which are obtained by the combination of three liquid detergent preparations A, B and C. The liquid cleaning agent preparations A, B and C differ in their composition from one another.

Unless explicitly stated otherwise, all percentages given in connection with the compositions described herein relate to% by weight, in each case based on the mixture in question. If physical states (solid, liquid) are mentioned in the present application, unless otherwise stated, these relate to room temperature (20 ° C.) at normal pressure of 1 bar.

The form of cleaning agent is characterized in that the

Detergent preparations are phosphate-free, i.e. that they contain less than 1% by weight of phosphate, preferably less than 0.5% by weight of phosphate, particularly preferably less than 0.1% by weight of phosphate and in particular no phosphate.

The cleaning agent preparation A contains one or more builders as the first essential component. The builders include in particular carbonates, organic cobuilders and silicates. Forms of cleaning agent according to the invention are preferably characterized in that the builder a1) is selected from the group of carbonates, bicarbonates, citrates, silicates, polymeric carboxylates and polymers containing sulfonic acid groups or mixtures thereof.

Preferred forms of detergent supply comprise a detergent preparation A which, based on its total weight, 2 to 50% by weight, preferably 6 to 45% by weight and

contains in particular 10 to 40% by weight of builder.

Detergent preparation A.

Organic cobuilders include, in particular, polycarboxylates / polycarboxylic acids, polymeric carboxylates, (poly) aspartic acid, polyacetals, dextrins and organic cobuilders. These classes of substances are described below. Usable organic builders are, for example, the polycarboxylic acids which can be used in the form of the free acid and / or their sodium salts, polycarboxylic acids being understood to mean those carboxylic acids which carry more than one acid function. For example, these are citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid,

Maleic acid, fumaric acid, sugar acids, provided that such use is not objectionable for ecological reasons, and mixtures of these. Polycarboxylic acids are preferably understood to mean non-polymeric polycarboxylates. Such polymeric polycarboxylates have a larger number, preferably 4 and more carboxylic acid-containing monomers. In addition to their builder action, the free acids typically also have the property of an acidifying component and thus also serve to establish a lower and milder pH of

Detergents. Citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixtures thereof can be mentioned in particular.

Particularly preferred cleaning agent preparations A according to the invention contain citrate as one of their essential builders. Forms of detergent, characterized in that the detergent preparation A, based on their total weight, contains 2 to 40% by weight, preferably 5 to 30% by weight and in particular 7 to 20% by weight of citrate, are preferred according to the invention. Citrate or citric acid have in particular in combination with phosphonate, in particular 1-hydroxyethane-1, 1-diphosphonic acid, and / or

Copolymers of acrylic acid with maleic acid which contain 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid have proven to be particularly suitable. Their relative molecular weight, based on free acids, is generally 2,000 to 70,000 g / mol, preferably 20,000 to 50,000 g / mol and in particular 30,000 to 40,000 g / mol. The amount of (co) polymeric polycarboxylates in the dishwasher detergents is preferably 0.5 to 20% by weight and in particular 3 to 10% by weight.

The group of these nonionic surfactants includes, for example, the C4-22 fatty alcohol (EO) io-8o-2-hydroxyalkyl ethers, in particular also the C8-12 fatty alcohol (EO) ₂₂ -2-hydroxydecyl ether and the C4-22 fatty alcohol (EO) ₄₀ -80-2-hydroxyalkyl ether.

The weight fraction of the nonionic surfactant in the total weight of the

Preferred hydrotropes are xylene sulfonate, cumene sulfonate, urea and / or / V-methylacetamide, particularly preferably cumene sulfonate and / or xylene sulfonate, especially cumene sulfonate. It was found that the use of hydrotropes, in particular cumene sulfonate, enormously improves the phase stability with regard to the temperature fluctuations. This can be observed in particular for preparations which contain at least one nonionic surfactant. It is particularly preferred that at least the detergent preparation C, in particular the detergent preparations C and B, have at least one hydrotrope, preferably xylene sulfonate, cumene sulfonate, urea and / or N-methylacetamide, particularly preferably cumene sulfonate and / or xylene sulfonate, especially cumene sulfonate, preferably in an amount from 2 to 25% by weight, in particular from 4 to 20% by weight and particularly preferably in an amount of 6 to 15, for example from 7 to 12% by weight, based on the total weight of the respective detergent preparation.

The composition of some exemplary cleaning agent forms according to the invention, comprising the cleaning agent preparations A, B and C, can be found in the following tables.

The combination of cleaning agents described above is packaged using a packaging agent in which the cleaning agent preparations A, B and C are present separately from one another. This separation can be achieved, for example, by separate receiving chambers, each of these receiving chambers containing one of the cleaning agents combined with one another. Examples of such assembly forms are cartridges with two, three, four or more separate receiving chambers, for example two, three, four or multi-chamber bottles. By separating the cleaning agents of different compositions, undesirable reactions due to chemical incompatibility can be excluded.

The viscosity of all cleaning agent preparations A, B and C is preferably less than 120 mPas, in particular from 1 to 100 mPas, in particular 10 to 80 mPas, preferably 20 to 60 mPas (measured at 20 ° C. with a Brookfield instrument LVDV II +, spindle 31, 100 rpm). This has the advantage that the detergent preparations from the packaging material can only be opened by opening a valve on the underside of the packaging material (in particular the cartridge) on the basis of gravity, preferably without the involvement of electrical or electronic means, e.g. Pumps etc. can be dosed. At the same time, the chambers are preferably largely completely emptied, i.e. without large residual amounts of the dosed

Detergent preparations. This is advantageous for the consumer and for the environment because only small amounts of the detergent preparations are unused in the chambers of the

The packaging or the cartridge remain.

In addition to preparations A, B and C, according to a particularly preferred

Embodiment in the packaging means is additionally at least one active substance composition which is present separately from the cleaning agent preparations, in particular from the cleaning agent preparations A, B and C and which contains at least one carrier material, preferably a water-insoluble carrier material, and at least one active substance D. These are preferably In a particularly preferred embodiment of the present invention, the polymeric carrier material of the particles consists at least in part of ethylene / vinyl acetate copolymer. Another preferred subject of the present application is therefore one

Detergent supply form as described above, characterized in that a polymeric carrier material contains at least 10% by weight, preferably at least 30% by weight, particularly preferably at least 70% by weight of ethylene / vinyl acetate copolymer, preferably entirely of ethylene / vinyl acetate copolymer is made.

Ethylene / vinyl acetate copolymers is the name for copolymers of ethylene and vinyl acetate. This polymer is generally produced in a process comparable to the production of low density polyethylene (LDPE). With a

Increasing proportion of vinyl acetate, the crystallinity of the polyethylene is interrupted and in this way the melting and softening points or the hardness of the resulting products are reduced. The vinyl acetate also makes the copolymer more polar and thus improves its adhesion to polar substrates.

The ethylene / vinyl acetate copolymers described above are widely available commercially, for example under the tradename Elvax ^® (Dupont). Particularly suitable in the context of the present invention, polyvinyl alcohols are, for example Elvax ^® 265, Elvax ^® 240, Elvax ^® 205W, Elvax ^® 200W, as well as Elvax ^® 360. Also suitable are, for example, products available under the trade Evatane® (Arkema).

In the context of the present invention, in particular in the area of scenting the interior of automatic dishwashers, active substance compositions are particularly preferred in which ethylene / vinyl acetate copolymer is used as the polymeric carrier material and this copolymer contains 5 to 50% by weight of vinyl acetate, preferably 10 to 40% by weight .-% vinyl acetate and in particular 20 to 30 wt .-% vinyl acetate, each based on the total weight of the copolymer contains. Other suitable carrier materials are the cyclodextrins.

As an alternative or in addition to the aforementioned carrier materials, inorganic carrier materials are preferably also used. Be particularly preferred

Forms of cleaning agent, characterized in that at least one of the carrier materials is an inorganic carrier material, preferably a silicate, phosphate or borate.

The silicates, phosphates or borates are preferably in the form of a glass, particularly preferably in the form of a water-soluble glass. Particularly preferred glasses are glasses containing zinc and / or bismuth, in particular those containing bismuth phosphate and / or

Glasses containing zinc phosphate. In such a case, the carrier material is water-soluble and contains in its substance, the active ingredient, in particular the glass corrosion inhibitors zinc and / or bismuth) in the carrier material.

In a preferred embodiment, the detergent dosage forms can contain such zinc or bismuth-containing glasses, particularly preferably zinc phosphate-containing glasses, in addition to a further active ingredient composition comprising a carrier material, preferably a

contain water-insoluble carrier material and at least one active ingredient D. These can then be contained in a common chamber or in separate chambers, in particular in one or more chambers which have openings, in particular openings such that the washing liquor and / or the air can flow through them. Preferred forms of cleaning agents are those which contain a glass containing zinc phosphate or bismuth phosphate and furthermore at least one, preferably two, three or more

Contain active ingredient compositions which comprise one or more fragrances and / or one or more fragrance scavengers as active ingredients.

In the context of the present application, in particular thermoplastic

Backing materials or backing materials which plastically deform under the influence of the ambient temperatures occurring during use are particularly preferred. Through the plastic

Deformation of the carrier materials in the course of one or more applications will result in a change in the carrier material surface, in particular a change in the size of the

Carrier material surface achieved, which in turn has an advantageous effect on the release profile and the release kinetics of the active cleaning compositions contained in the active ingredient compositions. Dosing devices, characterized in that at least one polymeric carrier material has a melting or softening point between 40 and 125 ° C, preferably between 60 and 100 ° C, particularly preferably a melting point of 70 to 90 ° C and in particular between 73 and 80 ° C ( preferred method of determination for the

Melting point according to ISO 1 1357-3) are preferred according to the invention.

The forms of cleaning agent according to the invention are particularly suitable for

Multiple dosing of the active ingredients included in them. In order to ensure such multiple dosing via a large number of cleaning processes, it has proven to be advantageous to use only water-insoluble carrier materials. These water-insoluble

Backing materials also simplify the manufacture of the inventive forms. Preferred forms of offer are therefore characterized in that all used

Carrier materials are insoluble in water.

The active substance compositions can in principle all, and / or depending on the chemical and physical properties of the carrier materials realizable physical states Take spatial forms. In a further embodiment, at least one of the

Active ingredient compositions as a gel.

In a further embodiment, at least one of the active substance compositions is in the form of a solid. Active ingredient compositions in the form of individual blocks comprising an entire active ingredient composition are used with particular preference.

The active substance compositions can preferably be in particulate form, the active substance compositions in which the carrier material comprises at least one of the

Active ingredient compositions are in particle form, these particles preferably having an average diameter of 0.5 to 20 mm, preferably 1 to 10 mm and in particular 3 to 6 mm, are particularly preferred.

Active ingredient compositions which comprise at least one colored active ingredient composition are particularly preferably used. The coloring of at least one of the active ingredient compositions enables an optical differentiation of these compositions to be achieved and the multiple use of these different compositions can be clarified in a simple manner. Furthermore, the dyes are also suitable as an indicator, in particular as a consumption indicator for the colored active ingredient compositions.

Preferred dyes, the selection of which is not difficult for the person skilled in the art, have a high storage stability and insensitivity to the other ingredients of the agents and to light, and no pronounced substantivity to the substrates to be treated with the dye-containing agents, such as glass, ceramics or plastic tableware, to be precise stain.

When choosing the colorant, it must be borne in mind that the colorants are high

Storage stability and insensitivity to light and no excessive affinity for glass, ceramics or plastic dishes. At the same time, when choosing suitable colorants, it must also be taken into account that colorants have different stabilities against oxidation. In general, water-insoluble colorants are more stable to oxidation than water-soluble colorants. Depending on the solubility and thus also on the sensitivity to oxidation, the concentration of the colorant in the cleaning agents varies. In the case of colorants which are readily water-soluble, colorant concentrations in the range from a few 10 ² to 10 ³ % by weight are typically selected. In contrast, in the case of the pigment dyes which are particularly preferred on account of their brilliance but are less readily water-soluble, the suitable concentration of the colorant in cleaning agents is typically a few 10 ³ to 10 ⁴ % by weight. According to a preferred embodiment, the form of the detergent is characterized in that the at least one active ingredient D is selected from the group of fragrances, preferably linalyl acetate, dihydromyrcenol, citronellonitrile, menthyl acetate,

Methylphenylbutanol, eucalyptol and mixtures thereof, scent scavengers, e.g. Zinc ricinoleate, cyclodextrins, 2-menthyl-5-cyclohexylpentanol and 1-cyclohexylethanol, in particular

Zinc ricinoleate; Dyes, glass corrosion inhibitors, antimicrobial agents, germicides or fungicides and mixtures thereof, preferably mixtures of at least one fragrance scavenger, preferably with one, two, three or more fragrances and / or at least one dye.

Mixtures of at least one fragrance, preferably two, three or more fragrances and at least one dye, are further preferred.

Individual perfume oils or fragrances can be used in the context of the present invention

Fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. However, are preferred

Mixtures of different fragrances are used, which together produce an appealing fragrance. Such perfume oils can also contain natural fragrance mixtures as are available from plant sources, e.g. Pine, citrus, jasmine, patchouly, rose or ylang-ylang oil.

In order to be perceptible, a fragrance must be volatile, whereby in addition to the nature of the functional groups and the structure of the chemical compound, the molar mass also plays an important role. Most odoriferous substances have molecular weights of up to about 200 daltons, while molecular weights of 300 daltons and more are an exception. Due to the different volatility of odoriferous substances, the smell of a perfume or fragrance composed of several odoriferous substances changes during evaporation, whereby the odor impressions are described in "top note" (top note), "heart or middle note" (middle note or body ) and "base note" (end note or dry out). Since the smell is largely based on the intensity of the smell, the top note of a perfume or

Fragrance not solely from volatile compounds, while the base note is largely from less volatile, i.e. non-stick fragrances. When composing perfumes, more volatile fragrances can be bound to certain fixatives, for example, which prevents them from evaporating too quickly. In the subsequent classification of the fragrances into more volatile or "adherent" fragrances, nothing is said about the odor impression and whether the corresponding fragrance is perceived as a top or heart note.

The fragrances can be processed directly, but it can also be advantageous to apply the fragrances to carriers which ensure a long-lasting fragrance due to a slower fragrance release. Cyclodextrins, for example, have proven themselves as such carrier materials, the Cyclodextrin-perfume complexes can also be coated with other auxiliaries.

According to the invention, particularly preferred fragrances are linalyl acetate, dihydromyrcenol,

Citronellonitrile, menthyl acetate, methylphenylbutanol and / or eucalyptol and mixtures thereof.

The known ricenolates, in particular the zinc ricenoleates, can be used, for example, as scent catchers (or, as is also used synonymously below, odor neutralizers or fragrance neutralizers, agents against malodour or bad odors). Also preferred are 2-menthyl-5-cyclohexylpentanol and 1-cyclohexylethanol. Activated carbon and / or cyclodextrins and / or zeolites, preferably acid-modified zeolites, can also be used with particular preference. Zinc ricinoleate alone or in combination with one or more of the above-mentioned fragrances and / or scent scavengers is particularly preferred, since it also has a positive effect on the inhibition of glass corrosion during the rinsing process.

To combat microorganisms, as an alternative or in addition to the above. Fragrances and / or fragrance scavengers antimicrobial agents are used. Depending on the antimicrobial spectrum and mechanism of action, a distinction is made between bacteriostatics and bactericides, fungistatics and fungicides, etc. Important substances from these groups are, for example, benzalkonium chlorides, alkylarlylsulfonates, halophenols and

Phenol mercuric acetate, although these compounds can also be dispensed with entirely.

In principle, the active substances can be contained in the active substance preparations in any amounts. However, dosing devices are particularly preferred in which the proportion by weight of the active ingredient (s) is 1 to 70% by weight, preferably 10 to 60% by weight, particularly preferably 20 to 50% by weight, in particular 30 to 40% by weight, is based in each case on the total weight of the active ingredient composition (s).

If more than one active ingredient composition is present in the detergent form, these can be present separately from one another or next to one another in the packaging means of the detergent form. The different active ingredient compositions can preferably be side by side, that is to say in direct contact with one another, in the

Packaging in the form of detergent is available.

It is particularly advantageous if an active ingredient composition D, in particular comprising fragrances and / or scent scavengers, and at the same time formic acid is used as an acidifying agent in preparation C. The formic acid itself has a slightly pungent smell, which is noticeable to sensitive consumers. Due to the separate storage of the Active ingredient composition and the release of the at least one active ingredient D, in particular if it is one or more fragrances, in particular those preferred above, and / or one or more fragrance scavengers, in particular, for example, zinc ricinoleate, does not occur during the dishwashing process or in the period between the cleaning cycles an unpleasant smell inside the dishwasher.

Another object of the present application is a cleaning agent supply form, comprising

a) a cleaning agent preparation A according to the invention in an amount sufficient to carry out an automatic dishwashing process at least twice, preferably at least four times and in particular at least eight times;

b) at least one further cleaning agent preparation B different from A in an amount sufficient to carry out an automatic dishwashing process at least twice, preferably at least four times and in particular at least eight times;

c) a further cleaning agent preparation C different from A and B in an amount sufficient to carry out an automatic dishwashing process at least twice, preferably at least four times and in particular at least eight times; d) optionally at least one other of A, B and C.

Active ingredient composition in a for the at least twice, preferably at least four times and in particular at least eight times, a machine

Dishwashing method sufficient amount, which contains at least one carrier material, preferably a water-insoluble carrier material, and at least one active ingredient D;

e) a cartridge for the cleaning agent preparations A, B and C or A, B, C and D, in which the cleaning agent preparations A, B, C or A, B, C and D are separated from one another

Admission chambers are available.

Another object of the present application is a detergent dosing system comprising

Active ingredient composition in one for at least two, preferably at least four and in particular at least eight times a machine

Admission chambers are available;

f) a dispenser detachably connected to the cartridge.

In a preferred embodiment, the cartridges described above are the

Provide forms of detergent with a dispenser that can be detached from the cartridge. Such a metering device can be connected to the cartridge, for example, by means of an adhesive, snap-in, snap or plug connection. Filling the cartridge is simplified, for example, by separating the cartridge and the metering device. Alternatively, the detachable

Connection of cartridge and dosing device, the exchange of cartridges on the dosing device.

Such an exchange can be indicated, for example, when the cleaning program is changed or after the cartridge has been completely emptied.

A particularly preferred subject matter of this application is a detergent dosing system comprising

a) a cleaning agent supply form according to the invention, comprising an amount of cleaning agent preparations A, B and C or A, B, C and D sufficient for carrying out an automatic dishwashing process at least twice, preferably at least four times and in particular at least eight times; b) a dispenser detachably connected to the form of the detergent.

Of course, forms of detergent are also conceivable in which the cartridge and the dosing device are permanently connected to one another.

The present application furthermore relates to a detergent dosing system comprising

a) a cleaning agent supply form according to the invention, comprising an amount of cleaning agent preparations A, B and C or A, B, C and D sufficient for carrying out an automatic dishwashing process at least twice, preferably at least four times and in particular at least eight times; b) a dosing device that is permanently connected to the form of the detergent

The above-mentioned detergent dosing systems, comprising the form of detergent according to the invention (and optionally one or two more, of the one according to the invention)

Detergent preparations A, B and C or A, B, C and D various In a preferred embodiment, compositions, a cartridge and a dosing device detachably connected to the cartridge are present in a common outer packaging, the filled cartridge and the dosing device being particularly preferably contained separately from one another in the outer packaging. The outer packaging is used for storage, transport and presentation of the form of cleaning agent according to the invention and protects it from dirt, shock and impact. For the purpose of presentation in particular, the

Outer packaging should be made at least partially transparent.

As an alternative or in addition to an outer packaging, there is of course the possibility of combining the cleaning agent form according to the invention with a

Market dishwasher. Such a combination is particularly advantageous in cases where the course of the automatic dishwashing process (e.g. duration,

Temperature curve, water supply) and the detergent formulation or the control electronics of the dosing device are coordinated.

The dosing system according to the invention consists of the basic components of a cartridge filled with the cleaning agent according to the invention and a dosing device which can be coupled to the cartridge and which in turn is formed from further assemblies, such as, for example, component carrier, actuator, closure element, sensor, energy source and / or control unit.

It is preferred that the metering system according to the invention is movable. Movable in the sense of this application means that the metering system is not inextricably linked to a water-carrying device such as a dishwasher or the like, but rather can be removed from a dishwasher by the user or positioned in a dishwasher, i.e. can be handled independently

According to an alternative embodiment of the invention, it is also conceivable that the metering device is not releasably connected to a water-carrying device such as a dishwasher or the like for the user and only the cartridge is movable.

Since the preparations to be dosed can have a pH between 2 and 14, in particular 2 and 12, depending on the intended use, all components of the dosing system that come into contact with the preparations should have an appropriate acid and / or alkali resistance. Furthermore, these components should be largely chemically inert, for example against nonionic surfactants, enzymes and / or fragrances, through a suitable choice of material.

A cartridge in the sense of this application is understood to mean a packaging material which is suitable for enveloping or holding together flowable or scatterable preparations and which can be coupled to a dispenser for dispensing the preparation. In particular, a cartridge can also comprise a plurality of chambers which are different from one another

Compositions can be filled. It is also conceivable for a plurality of containers to be arranged to form a cartridge unit.

It is advantageous that the cartridge has at least one outlet opening, which is arranged in such a way that the preparation can be released from the container under the force of gravity in the use position of the metering device. As a result, no further funding is required to release preparation from the container, which means that the construction of the metering device can be simple and the production costs can be kept low.

In a preferred embodiment of the invention, at least one second chamber is provided for receiving at least one second flowable or scatterable preparation, the second chamber having at least one outlet opening which is arranged in such a way that product release from the second chamber caused by gravity is in the use position of the metering device is effected. The arrangement of a second chamber is particularly advantageous when preparations are stored in the separate containers, which are usually not stable with one another, such as bleaching agents and enzymes.

Furthermore, it is necessary according to the invention that more than two, in particular three, four or five chambers are provided in or on a cartridge. In particular, at least one of the chambers for dispensing active substances) D, such as a glass corrosion inhibitor, is one

Fragrance or in particular an odor neutralizer to the environment, designed so that it has openings through which the washing liquor and / or the air can flow.

In a further embodiment of the invention, the cartridge is formed in one piece. As a result, the cartridges can be formed inexpensively in one production step, in particular by means of suitable blow molding processes. The chambers of a cartridge can be separated from one another, for example, by webs or material bridges.

The cartridge can also be formed in several pieces by components that are injection molded and then joined together. Furthermore, it is conceivable that the cartridge is formed in such a way that at least one chamber, preferably all chambers, can be removed individually from the dosing device or inserted into the dosing device. This makes it possible to replace a chamber that has already been emptied if the consumption of a preparation from one chamber varies, while the others, which may still be filled with preparation, remain in the metering device. In this way, a targeted and needs-based refilling of the individual chambers or their preparations can be achieved. The chambers of a cartridge can be fixed to one another by suitable connection methods, so that a container unit is formed. The chambers can be detachable or non-detachable by means of a suitable positive, non-positive or material connection

be fixed against each other.

In particular, the fixation by one or more of the connection types from the group of snap-in connections, Velcro connections, press connections, fusion connections, adhesive connections, welded connections, soldered connections, screw connections,

Wedge connections, clamp connections or bounce connections are made. In particular, the fixation can also be formed by a shrink tube (so-called sleeve), which is pulled over the entire or sections of the cartridge in a heated state and firmly encloses the chambers or the cartridge in the cooled state.

In order to provide advantageous residual emptying properties of the chambers, the bottom of the chambers can be inclined in a funnel shape towards the discharge opening. Furthermore, the inner wall of a chamber can be formed by a suitable choice of material and / or surface configuration in such a way that a slight material adhesion of the preparation to the inner one

Chamber wall is realized. This measure can also further optimize the residual emptiness of a chamber.

The chambers of a cartridge can have the same or different filling volumes. In a configuration with two chambers, the ratio of the container volumes is preferably 5: 1, in a configuration with three chambers preferably 4: 1: 1, whereby this

Configurations are particularly suitable for use in dishwashers.

As mentioned above, the cartridge preferably has 3, 4, 5 or 6 chambers. For the use of such a cartridge in a dishwasher, it is particularly preferred that the first chamber contains an alkaline cleaning preparation, the second chamber contains an enzymatic preparation and the third chamber contains a rinse aid, the volume ratio of the chambers being approximately 4: 1: 1. The fourth chamber contains the at least one

Active ingredient composition comprising the at least one active ingredient D and a carrier material, preferably a water-insoluble carrier material.

A dosing chamber can be formed in or on a chamber in the direction of flow of the preparation in front of the outlet opening. The metering chamber determines the amount of preparation that is to be released into the environment when preparation is released from the chamber. This is particularly advantageous if the closure element of the metering device, which causes the preparation to be dispensed from a chamber into the environment, can only be put into a dispensing and a closed state without checking the dispensing quantity. Through the The dosing chamber then ensures that a predefined amount of preparation is released without an immediate feedback of the dispensed preparation quantity. The metering chambers can be formed in one piece or in several pieces.

According to a further advantageous development of the invention, one or more chambers each have a chamber opening that can be closed in a liquid-tight manner in addition to an outlet opening. This chamber opening makes it possible, for example, to refill the preparation stored in this chamber.

To ventilate the cartridge chambers, ventilation options can be provided in particular in the head region of the cartridge, in order to ensure pressure compensation when the filling level of the chambers falls between the interior of the cartridge chambers and the surroundings. These ventilation options can be designed, for example, as a valve, in particular a silicone valve, micro-openings in the cartridge wall or the like.

According to a further embodiment, if the cartridge chambers are not to be ventilated directly, but rather via the metering device or no ventilation, e.g. If flexible containers, such as bags, are provided, this has the advantage that when the container is elevated

Temperatures in the course of a dishwashing cycle of a dishwasher, due to the heating of the chamber contents, a pressure is built up which pushes the preparations to be dosed in the direction of the outlet openings, so that the cartridge can be easily emptied. Furthermore, with such an air-free packaging there is no risk of oxidation of substances in the preparation, which makes bag packaging or bag-in-bottle packaging appear expedient, in particular for preparations sensitive to oxidation.

The cartridge usually has a filling volume of <5,000 ml, in particular <1,000 ml, preferably <500 ml, particularly preferably <250 ml, very particularly preferably <50 ml.

The cartridge can take any shape. For example, it can be cube-shaped, spherical or plate-like.

The shape of the cartridge and the metering device can in particular be designed in such a way that they ensure as little loss of useful volume as possible, in particular in a dishwasher.

To use the dosing device in dishwashers, it is particularly advantageous to shape the device based on the dishes to be cleaned in dishwashers. For example, this can be plate-shaped, approximately in the dimensions of a plate. As a result, the metering device can be positioned in a space-saving manner, for example in the lower basket of the dishwasher will. Furthermore, the correct positioning of the dosing unit is immediately intuitive for the user due to the plate-like shape. The cartridge preferably has a ratio of height: width: depth between 5: 5: 1 and 50: 50: 1, particularly preferably of about 10: 10: 1. The “slim” design of the dosing device and the cartridge makes it possible, in particular, to position the device in the lower cutlery basket of a dishwasher in the receptacles provided for plates. This has the advantage that the preparations dispensed from the dosing device go directly into the washing liquor and cannot adhere to other items to be washed.

Customary household dishwashers are usually designed in such a way that the arrangement of larger items to be washed, such as pans or large plates, is provided in the lower basket of the dishwasher. In order to avoid a non-optimal positioning of the dosing system by the user in the upper basket, in an advantageous embodiment of the invention the dosing system is dimensioned such that the dosing system can only be positioned in the receptacles provided for the lower basket. For this purpose, the width and the height of the metering system can be chosen in particular between 150 mm and 300 mm, particularly preferably between 175 mm and 250 mm.

However, it is also conceivable to design the dosing unit in a cup shape with an essentially circular or square base area.

In order to protect heat-sensitive components of a preparation in a cartridge from exposure to heat, it is advantageous to manufacture the cartridge from a material with a low thermal conductivity.

A further possibility for reducing the influence of heat on a preparation in a chamber of the cartridge is to isolate the chamber by means of suitable measures, e.g. through the use of thermal insulation materials such as styrofoam, which completely or partially enclose the chamber or the cartridge in a suitable manner.

In a preferred embodiment of the invention, the cartridge has an RFID label that at least contains information about the contents of the cartridge and that can be read out by the sensor unit.

This information can be used to select a dosing program stored in the control unit. This can ensure that an optimal dosing program is always used for a specific preparation. It can also be provided that, in the absence of an RFID label or an RFID label with an incorrect or incorrect identifier, the metering device does not dose and instead generates an optical or acoustic signal that the user is aware of the error points out. In order to rule out misuse of the cartridge, the cartridges can also have structural elements which correspond to corresponding elements of the metering device according to the

Key-lock principle interact so that, for example, only cartridges of a certain type can be coupled to the dosing device. Furthermore, this configuration makes it possible for information about the cartridge coupled to the metering device to be sent to the

Control unit are transmitted, whereby a control of the metering device can be carried out which is coordinated with the content of the corresponding container.

The cartridge is designed in particular for receiving flowable cleaning agents. Such a cartridge particularly preferably has a plurality of chambers for spatially separated accommodation of preparations of a cleaning agent which are in each case different from one another. The cartridge can be designed so that it is detachable or fixed in or on the

Dishwasher can be arranged.

The control unit, sensor unit and at least one actuator required for operation are integrated in the dosing device. An energy source is preferably also arranged in the metering device.

Preferably, the dosing device consists of a splash-proof housing that prevents the ingress of splash water, such as when used in a

Dishwasher can prevent inside of the dispenser.

It is particularly preferred that the dosing device comprises at least one first interface, which interacts with a corresponding interface designed in or on a water-carrying device, in particular a water-carrying household appliance, preferably a dishwasher, such that a transmission of electrical energy from the water-carrying device to the dosing device is realized.

In one embodiment of the invention, the interfaces are formed by plug connectors. In a further embodiment, the interfaces can be designed in such a way that wireless transmission of electrical energy is effected.

In an advantageous further development of the invention, a second interface is provided on the metering device and the water-carrying device, such as a dishwasher

Transmission of electromagnetic signals, which in particular represent the operating status, measurement and / or control information of the metering device and / or the water-carrying device such as a dishwasher. An adapter can be used to easily couple the dosing system to a water-bearing household appliance. The adapter is used for the mechanical and / or electrical connection of the dosing system to the water-bearing household appliance.

The adapter is, preferably fixed, connected to a water-carrying line of the household appliance. However, it is also conceivable to use the adapter for positioning in or on

To provide household appliance in which the adapter is caught by the water flow and / or spray of the household appliance.

The adapter makes it possible to run a dosing system for both a self-sufficient and a "build-in" version. It is also possible to design the adapter as a type of charging station for the metering system, in which, for example, the energy source of the metering device is charged or data is exchanged between the metering device and the adapter.

The adapter can be arranged in a dishwasher on one of the inner walls of the washing chamber, in particular on the inner side of the dishwasher door. However, it is also conceivable that the adapter as such is positioned so that it is not accessible to the user in the water-conducting household appliance, so that the metering device is inserted into the adapter, for example during assembly of the household device, the adapter, the metering device and the household device being designed in this way that a cartridge can be coupled to the dosing device by the user.

The cleaning agent supply forms according to the invention are suitable for use in dishwashing, but the use of a cleaning agent according to the invention is nevertheless

As stated at the outset, the cleaning agents according to the invention are notable for particular physical and chemical stability

Temperature fluctuations, off. The cleaning agents according to the invention are therefore particularly suitable for metering by means of a metering system located in the interior of a dishwasher. Such a dosing system, which can be immovably integrated into the interior of the dishwasher (machine-integrated dosing device), however

can of course also be introduced as a movable device into the interior (self-sufficient dosing device), contains the multiple for carrying out a mechanical one

An example of a movable cartridge is a container that the consumer places in the interior of the dishwasher and remains there throughout the course of a cleaning cycle. Such a cartridge can be integrated into the interior, for example by simply inserting it into the cutlery or crockery basket, but can also be removed from the interior of the dishwasher by the consumer.

The detergent or the detergent combination is dosed from the cartridge into the interior of the dishwasher, as described above, preferably by means of a dosing device that can be detached from the cartridge. Such a metering device can be connected to the cartridge by means of an adhesive, latching, snap or plug connection. Cartridges with an inseparably connected dosing device can of course also be used.
