Description

Die Erfindung betrifft eine wasserlösliche Verpackung, die ein Mittel und eine wasserlösliche Umhüllung umfasst. Die Erfindung betrifft auch ein Verfahren zur Herstellung einer wasserlöslichen Verpackung.The invention relates to a water-soluble packaging comprising an agent and a water-soluble coating. The invention also relates to a process for producing a water-soluble packaging.

Wasch- oder Reinigungsmittel sind heute für den Verbraucher in vielfältigen Angebotsformen erhältlich. Neben Pulvern und Granulaten umfasst dieses Angebot beispielsweise auch Flüssigkeiten, Gele oder Portionspackungen (Tabletten oder gefüllte Beutel).Detergents or cleaners are now available to the consumer in a variety of forms. In addition to powders and granules, this offer includes, for example, liquids, gels or sachets (tablets or filled pouches).

Insbesondere Portionspackungen in Form von wasserlöslichen Verpackungen mit flüssigen Wasch- oder Reinigungsmitteln werden immer beliebter, erfüllen sie einerseits den Wunsch des Verbrauchers nach vereinfachter Dosierung und andererseits bevorzugen immer mehr Verbraucher flüssige Wasch- oder Reinigungsmittel.In particular, portion packs in the form of water-soluble packaging with liquid detergents or cleaners are becoming increasingly popular, they fulfill the one hand, the consumer's desire for simplified dosage and on the other hand more and more consumers prefer liquid detergents or cleaners.

Ein solcher wasserlöslicher Beutel enthält ein Mittel und eine transparente, wasserlösliche Umhüllung.Such a water-soluble bag contains an agent and a transparent, water-soluble wrapper.

Aus der WO 96/08555 A1 ist ein verpacktes Reinigungsmittel zum Geschirrspülen bekannt, welches mit dem Bittermittel Bitrex® (Denatoniumbenzoat) beschichtet ist, um zu verhindern, dass Kinder das verpackte Reinigungsmittel versehentlich verschlucken.From the WO 96/08555 A1 A packaged dishwashing detergent is known which is coated with Bitrex® (denatonium benzoate) bitumen to prevent children from inadvertently swallowing the packaged detergent.

Denatoniumbenzoat gilt als die bitterste bekannte Substanz und besitzt einen Bitterwert größer 100.000.000.Denatonium benzoate is considered the bitterest known substance and has a bitter value greater than 100,000,000.

Ein Nachteil bei der Beschichtung einer wasserlöslichen Verpackung mit Bitrex® liegt darin, dass die Anwender der wasserlöslichen Verpackung die Verpackung zum Dosieren in die Hand nehmen und so auch in Kontakt mit dem Bitrex® kommen. Führt ein Anwender nach dem Berühren der wasserlöslichen Verpackung seine Hand in Richtung Mund, reichen schon geringe, an der Hand verbliebene Mengen Bitrex®, um den Geschmackssinn für ein paar Stunden negativ zu beeinträchtigen.A disadvantage of coating a water-soluble packaging with Bitrex® is that the users of the water-soluble packaging take the packaging for dosing into their hands and thus also come into contact with the Bitrex®. If a user, after touching the water-soluble packaging, puts his hand in the direction of the mouth, small amounts of Bitrex® remaining in the hand are enough to negatively affect the sense of taste for a few hours.

Aufgabe der Erfindung ist es daher, wasserlösliche Verpackungen mit hoher Kindersicherheit, aber ohne negative Effekte bei normaler Anwendung bereit zu stellen.The object of the invention is therefore to provide water-soluble packaging with high child safety, but without negative effects in normal use.

Diese Aufgabe wird durch eine wasserlösliche Verpackung, die ein Mittel und eine wasserlösliche Umhüllung enthält, bei dem die wasserlösliche Umhüllung einen Bitterstoff in einer Verdünnung von mindestens 1 : 250 enthält., gelöst.This object is achieved by a water-soluble package containing an agent and a water-soluble wrapper, wherein the water-soluble wrapper contains a bittering agent in a dilution of at least 1: 250.

Es hat sich überraschenderweise gezeigt, dass wenn der Bitterstoff in der wasserlöslichen Umhüllung enthalten ist, bei regulärer Verwendung der wasserlöslichen Verpackung keine oder kaum bitter schmeckende Substanzen auf der Hand eines Anwenders der wasserlöslichen Verpackung verbleiben und somit auch bei versehentlichem Kontakt der Hand mit dem Mund die Geschmacksknospen des Anwenders nicht unangenehm gereizt werden.It has surprisingly been found that when the bitter substance is contained in the water-soluble wrapper, with regular use of the water-soluble packaging no or hardly bitter-tasting substances remain in the hands of a user of the water-soluble packaging and thus in case of accidental contact of the hand with the mouth Taste buds of the user should not be irritated unpleasantly.

Wasserlösliche VerpackungWater-soluble packaging

Gegenstand der Erfindung ist eine wasserlösliche Verpackung, die ein Mittel und eine wasserlösliche Umhüllung enthält. Die wasserlösliche Umhüllung enthält einen Bitterstoff.The invention relates to a water-soluble packaging containing an agent and a water-soluble wrapper. The water-soluble coating contains a bitter substance.

Eine wasserlösliche Verpackung enthält eine wasserlösliche Umhüllung, welche eine geschlossene Struktur ausbildet, die in ihrem Inneren eine oder mehrere Kammern zur Aufnahme eines oder mehrerer Mittel aufweist. Die wasserlösliche Umhüllung wird vorzugsweise durch ein wasserlösliches Folienmaterial gebildet.A water-soluble package contains a water-soluble envelope which forms a closed structure having in its interior one or more chambers for receiving one or more agents. The water-soluble coating is preferably formed by a water-soluble film material.

Die wasserlösliche Verpackung kann formstabil oder verformbar ausgebildet sein.The water-soluble packaging may be dimensionally stable or deformable.

Die wasserlösliche Verpackung kann als formstabiler Behälter, beispielsweise in Form einer Kapsel, Box, Dose oder eines Containers ausgebildet sein.The water-soluble packaging may be formed as a dimensionally stable container, for example in the form of a capsule, box, box or container.

Es ist grundsätzlich jedoch auch möglich und bevorzugt, die wasserlösliche Verpackung als einen nicht formstabilen Behälter, beispielsweise als Beutel auszuformen. Die Form einer derartigen wasserlöslichen Verpackung kann den Gebrauchsgegebenheiten weitgehend angepasst werden. Es kommen beispielsweise verschiedenste Formen wie beispielsweise Schläuche, Kissen, Zylinder, Flaschen oder Scheiben in Frage.However, in principle it is also possible and preferred to mold the water-soluble packaging as a non-dimensionally stable container, for example as a bag. The shape of such a water-soluble packaging can be largely adapted to the conditions of use. There are, for example, various forms such as hoses, pillows, cylinders, bottles or discs in question.

Die wasserlösliche Verpackung kann eine oder mehrere Kammern zur Bevorratung eines oder mehrerer Mittel aufweisen. Bevorzugt weist die wasserlösliche Verpackung, zwischen zwei und fünf Kammern auf.The water soluble package may include one or more chambers for storing one or more agents. The water-soluble packaging preferably has between two and five chambers.

Wasserlösliche UmhüllungWater-soluble cladding

Die wasserlösliche Umhüllung wird vorzugsweise aus einem wasserlöslichen Folienmaterial, welches ausgewählt ist aus der Gruppe, bestehend aus Polymeren oder Polymergemischen, gebildet. Die Umhüllung kann aus einer oder aus zwei oder mehr Lagen aus dem wasserlöslichen Folienmaterial gebildet werden. Das wasserlösliche Folienmaterial der ersten Lage und der weiteren Lagen, falls vorhanden, kann gleich oder unterschiedlich sein. Besonders bevorzugt sind Folien, die beispielsweise zu Verpackungen wie Schläuchen oder Kissen verklebt und/oder versiegelt werden können, nachdem sie mit einem Mittel befüllt wurden.The water-soluble coating is preferably formed from a water-soluble film material selected from the group consisting of polymers or polymer blends. The wrapper may be formed of one or two or more layers of the water-soluble film material. The water-soluble film material of the first layer and the further layers, if present, may be the same or different. Particularly preferred are films which, for example, glued to packaging such as tubes or cushions and / or can be sealed after being filled with a medium.

Es ist bevorzugt, dass die wasserlösliche Umhüllung Polyvinylalkohol oder ein Polyvinylalkoholcopolymer enthält. Wasserlösliche Umhüllungen, die Polyvinylalkohol oder ein Polyvinylalkoholcopolymer enthalten, weisen eine gute Stabilität bei einer ausreichend hohen Wasserlöslichkeit, insbesondere Kaltwasserlöslichkeit, auf.It is preferable that the water-soluble coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer. Water-soluble coatings containing polyvinyl alcohol or a polyvinyl alcohol copolymer have a good stability with a sufficiently high water solubility, in particular cold water solubility on.

Geeignete wasserlösliche Folien zur Herstellung der wasserlöslichen Umhüllung basieren bevorzugt auf einem Polyvinylalkohol oder einem Polyvinylalkoholcopolymer, dessen Molekulargewicht im Bereich von 10.000 bis 1.000.000 gmol-1, vorzugsweise von 20.000 bis 500.000 gmol-1, besonders bevorzugt von 30.000 bis 100.000 gmol-1 und insbesondere von 40.000 bis 80.000 gmol-1 liegt.Suitable water-soluble films for producing the water-soluble coating are preferably based on a polyvinyl alcohol or a polyvinyl alcohol copolymer whose molecular weight is in the range of 10,000 to 1,000,000 gmol -1 , preferably 20,000 to 500,000 gmol -1 , more preferably 30,000 to 100,000 gmol -1 and especially from 40,000 to 80,000 gmol -1 .

Die Herstellung von Polyvinylalkohol geschieht üblicherweise durch Hydrolyse von Polyvinylacetat, da der direkte Syntheseweg nicht möglich ist. Ähnliches gilt für Polyvinylalkoholcopolymere, die aus entsprechend aus Polyvinylacetatcopolymeren hergestellt werden. Bevorzugt ist, wenn wenigstens eine Lage der wasserlöslichen Umhüllung einen Polyvinylalkohol umfasst, dessen Hydrolysegrad 70 bis 100 Mol-%, vorzugsweise 80 bis 90 Mol-%, besonders bevorzugt 81 bis 89 Mol-% und insbesondere 82 bis 88 Mol-% ausmacht.The production of polyvinyl alcohol is usually carried out by hydrolysis of polyvinyl acetate, since the direct synthesis route is not possible. The same applies to polyvinyl alcohol copolymers which are prepared from correspondingly polyvinyl acetate copolymers. It is preferred if at least one layer of the water-soluble coating comprises a polyvinyl alcohol whose degree of hydrolysis makes up 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol%.

Einem zur Herstellung der wasserlöslichen Umhüllung geeignetem Polyvinylalkohol-enthaltendem Folienmaterial kann zusätzlich ein Polymer ausgewählt aus der Gruppe umfassend (Meth)Acrylsäure-haltige (Co)Polymere, Polyacrylamide, Oxazolin-Polymere, Polystyrolsulfonate, Polyurethane, Polyester, Polyether, Polymilchsäure oder Mischungen der vorstehenden Polymere zugesetzt sein. Ein bevorzugtes zusätzliches Polymer sind Polymilchsäuren.In addition, a polymer selected from the group consisting of (meth) acrylic acid-containing (co) polymers, polyacrylamides, oxazoline polymers, polystyrenesulfonates, polyurethanes, polyesters, polyethers, polylactic acid, or mixtures of the above can be additionally used as a polyvinyl alcohol-containing film material suitable for producing the water-soluble coating Be added polymers. A preferred additional polymer is polylactic acids.

Bevorzugte Polyvinylalkoholcopolymere umfassen neben Vinylalkohol Dicarbonsäuren als weitere Monomere. Geeignete Dicarbonsäure sind Itaconsäure, Malonsäure, Bernsteinsäure und Mischungen daraus, wobei Itaconsäure bevorzugt ist.Preferred polyvinyl alcohol copolymers include, in addition to vinyl alcohol, dicarboxylic acids as further monomers. Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and mixtures thereof, with itaconic acid being preferred.

Ebenfalls bevorzugte Polyvinylalkoholcopolymere umfassen neben Vinylalkohol eine ethylenisch ungesättige Carbonsäure, deren Salz oder deren Ester. Besonders bevorzugt enthalten solche Polyvinylalkoholcopolymere neben Vinylalkohol Acrylsäure, Methacrylsäure, Acrylsäureester, Methacrylsäureester oder Mischungen daraus.Likewise preferred polyvinyl alcohol copolymers include, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its esters. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylates, methacrylates or mixtures thereof.

Es kann bevorzugt sein, dass das Folienmaterial der wasserlöslichen Umhüllung weitere Zusatzstoffe enthält. Das Folienmaterial der wasserlöslichen Umhüllung kann beispielsweise Weichmacher wie Dipropylenglycol, Ethylenglycol, Diethylenglycol, Propylenglycol, Glycerin, Sorbitol, Mannitol oder Mischungen daraus enthalten. Weitere Zusatzstoffe umfassen beispielsweise Freisetzungshilfen, Füllmittel, Vernetzungsmittel, Tenside, Antioxidationsmittel, UV-Absorber, Antiblockmittel, Antiklebemittel oder Mischungen daraus.It may be preferred that the film material of the water-soluble casing contains further additives. The film material of the water-soluble coating may contain, for example, plasticizers such as dipropylene glycol, ethylene glycol, diethylene glycol, propylene glycol, glycerol, sorbitol, mannitol or mixtures thereof. Other additives include, for example, release aids, fillers, crosslinking agents, surfactants, antioxidants, UV absorbers, Anti-blocking agents, anti-sticking agents or mixtures thereof.

Die wasserlösliche Umhüllung enthält einen Bitterstoff in einer Verdünnung von mindestens 1 : 250 und vorzugsweise in einer Verdünnung von mindestens 1 : 500.The water-soluble coating contains a bittering agent in a dilution of at least 1: 250 and preferably in a dilution of at least 1: 500.

Als Verdünnung wird in dieser Anmeldung der Vorgang des Sinkens der Konzentration des in der wasserlöslichen Umhüllung befindlichen Bitterstoffs verstanden. Eine Verdünnung von 1 : 250 bedeutet, dass sich in der wasserlöslichen Umhüllung ein Teil Bitterstoff pro 250 Teilen wasserlöslicher Umhüllung befindet.In this application, dilution is understood as the process of sinking the concentration of the bitter substance present in the water-soluble coating. A dilution of 1: 250 means that one part of bittern per 250 parts of water-soluble coating is in the water-soluble coating.

Als Bitterstoffe werden alle chemischen Verbindungen bezeichnet, die einen bitteren Geschmack aufweisen.Bitter substances are all chemical compounds that have a bitter taste.

In einer bevorzugten Ausführungsform enthält die wasserlösliche Umhüllung einen Bitterstoff, welcher vorzugsweise einen Bitterwert von mindestens 10.000 aufweist.In a preferred embodiment, the water-soluble coating contains a bittering agent, which preferably has a bitter value of at least 10,000.

Es ist insbesondere bevorzugt, dass der Bitterstoff einen Bitterwert von mindestens 100.000 aufweist. Je höher der Bitterwert ist, desto weniger Bitterstoff muss in die wasserlösliche Umhüllung eingebracht werden, um einen ausreichend hohen Bitterwert der wasserlöslichen Umhüllung zu erzeugen.It is particularly preferred that the bittering agent has a bitter value of at least 100,000. The higher the bitterness, the less bittering agent must be incorporated into the water-soluble wrapper to produce a sufficiently high bitterness of the water-soluble wrapper.

Es hat sich gezeigt, dass Lösungen von Bitterstoffe in reinem Wasser deutlich stärker bitter schmecken als Lösungen der Bitterstoffe in wässrigen Polyvinylalkohol-Lösungen. Der Effekt wird noch größer, wenn die wässrigen Polyvinylalkohol-Lösungen zu Polyvinylalkohol-Folien getrocknet werden.It has been found that solutions of bitter substances in pure water taste much more bitter than solutions of bitter substances in aqueous polyvinyl alcohol solutions. The effect becomes even greater when the aqueous polyvinyl alcohol solutions are dried to polyvinyl alcohol films.

Der Bitterwert ist der Kehrwert jener Verdünnung eines Stoffes, einer Flüssigkeit oder eines Extraktes, die eben noch bitter schmeckt.The bitterness is the inverse of the dilution of a substance, a liquid or an extract that just tastes bitter.

Zur Bestimmung des Bitterwertes wird das im Europäischen Arzneibuch (5. Ausgabe Grundwerk, Stuttgart 2005, Band 1 Allgemeiner Teil Monografiegruppen, 2.8.15 Bitterwert S. 278 ) beschriebene standardisierte Verfahren verwendet.To determine the bitterness value, the European Pharmacopoeia (5th Edition, Grundwerk, Stuttgart 2005, Volume 1 General Part Monograph Groups, 2.8.15 Bitterness p. 278 ) used standardized procedures.

Als Vergleich dient eine wässrige Lösung von Chininhydrochlorid, dessen Bitterwert mit 200.000 festgelegt ist. Dies bedeutet, dass 1 Gramm Chininhydrochlorid 200 Liter Wasser bitter macht. Die interindividuellen Geschmacksunterschiede bei der organoleptischen Prüfung der Bitterkeit werden bei diesem Verfahren durch einen Korrekturfaktor ausgeglichen.As a comparison serves an aqueous solution of quinine hydrochloride whose bitterness value is set at 200,000. This means that 1 gram of quinine hydrochloride makes 200 liters of water bitter. The interindividual taste differences in the organoleptic test of bitterness are compensated by a correction factor in this method.

Geeignete Bitterstoffe mit einem Bitterwert von mindestens 10.000, welche in dem Folienmaterial zur Herstellung der wasserlöslichen Umhüllung enthalten sein können, sind natürliche oder synthetische Bitterstoffe. Insbesondere bevorzugt sind die natürlichen Bitterstoffe mit einem Bitterwert von mindestens 10.000 ausgewählt aus der Gruppe bestehend aus Glycosiden, Isoprenoiden, Alkaloiden, Aminosäuren und Mischungen daraus.Suitable bittering agents having a bitter value of at least 10,000, which may be contained in the film material for producing the water-soluble coating, are natural or synthetic bitter substances. Particularly preferred are the natural bitter substances having a bitter value of at least 10,000 selected from the group consisting of glycosides, isoprenoids, alkaloids, amino acids and mixtures thereof.

Besonders bevorzugte Bitterstoffe mit einem Bitterwert von mindestens 10.000 sind Naringin (Bitterwert = 10.000), Saccharoseoctaacetat (Bitterwert = 100.000) Chininhydrochlorid, Denatoniumbenzoat (Bitterwert > 100.000.000) und Mischungen daraus.Particularly preferred bitter substances having a bitter value of at least 10,000 are naringin (bitter value = 10,000), sucrose octaacetate (bitter value = 100,000), quinine hydrochloride, denatonium benzoate (bitter value> 100,000,000), and mixtures thereof.

Es hat sich gezeigt, dass diese Bitterstoffe problemlos in die wasserlösliche Umhüllung eingebracht werden können, ohne dass die strukturelle Integrität der wasserlöslichen Umhüllung zerstört wird.It has been found that these bittering agents can be easily incorporated into the water-soluble casing without destroying the structural integrity of the water-soluble casing.

Zur Erzielung eines ausreichend bitteren Geschmacks der wasserlöslichen Umhüllung wird Saccharoseoctaacetat vorzugsweise in einer Verdünnung von 1 : 1.000 bis 1 : 500 und Denatoniumbenzoat vorzugsweise in einer Verdünnung von 1 : 100.000 bis 1 : 50.000 eingesetztTo obtain a sufficiently bitter taste of the water-soluble casing, sucrose octaacetate is preferably used at a dilution of 1: 1000 to 1: 500 and denatonium benzoate, preferably at a dilution of 1: 100,000 to 1: 50,000

Seit einiger Zeit sind die für Bittergeschmack zuständigen 25 Gene entschlüsselt, von denen es zusätzlich noch verschiedene Varianten gibt. Ist ein solches Gen nicht aktiv, bildet es keine Rezeptoren für bestimmte Bitterstoffe auf der Zungenoberfläche aus und dieser Mensch ist ein so genannter Nichtschmecker. Um sicherzustellen, dass möglichst viele Menschen, insbesondere Kinder, den Bittergeschmack wahrnehmen, kann der Einsatz einer Mischung verschiedener Bitterstoffe vorteilhaft sein.For some time now responsible for bitter taste 25 genes are decrypted, of which there are also still different variants. If such a gene is not active, it does not form receptors for certain bitter substances on the tongue surface and this human is a so-called non-smoker. To ensure that as many people as possible, especially children, perceive the bitter taste, the use of a mixture of different bitter substances may be advantageous.

Die Verdünnung des Bitterstoffes und somit die Menge an Bitterstoff in der wasserlöslichen Umhüllung hängt insbesondere von der gewünschten Intensität des Bittergeschmacks und von den weiteren Inhaltsstoffen der wasserlöslichen Umhüllung ab. So kann beispielsweise der Einsatz von Weichmachern wie Sorbitol in dem Folienmaterial zur Ausbildung der wasserlöslichen Umhüllung den bitteren Geschmack der wasserlöslichen Umhüllung abschwächen.The dilution of the bittering agent and thus the amount of bittering agent in the water-soluble coating depends in particular on the desired intensity of the bitter taste and on the other ingredients of the water-soluble coating. For example, the use of plasticizers such as sorbitol in the sheet material to form the water-soluble casing can mitigate the bitter taste of the water-soluble casing.

Es ist allerdings bevorzugt, dass die Menge an Bitterstoff pro wasserlöslicher Umhüllung zwischen 10 und 4000 ppm beträgt.However, it is preferred that the amount of bittering agent per water-soluble coating is between 10 and 4000 ppm.

Mittel, insbesondere flüssige, gelförmige oder feste Wasch- oder Reinigungsmittel zur Bevorratung in der wasserlöslichen VerpackungMeans, in particular liquid, gel or solid detergents or cleaners for storing in the water-soluble packaging

Neben der wasserlöslichen Umhüllung weist die wasserlösliche Verpackung ein Mittel auf. Dieses Mittel kann beispielsweise ein festes Mittel sein und ein Pulver, ein Granulat oder eine Tablette umfassen. Alternativ kann das Mittel ein flüssiges Mittel sein und ein Gel oder eine Flüssigkeit umfassen. Insbesondere bevorzugt ist das Mittel ein flüssiges oder festes Wasch- oder Reinigungsmittel, wobei flüssige Wasch- oder Reinigungsmittel besonders bevorzugt sind.In addition to the water-soluble casing, the water-soluble packaging has a means. For example, this agent may be a solid agent and may comprise a powder, granules or tablet. Alternatively, the agent may be a liquid agent and may comprise a gel or a liquid. In particular, the agent is preferably a liquid or solid detergent or cleaning agent, with liquid detergents or cleaning agents being particularly preferred.

In dieser Ausführungsform enthält die erste Kammer vorzugsweise ein flüssiges Mittel und die zweite Kammer ein festes oder ein flüssiges Mittel. Alternativ können beide Kammern ein festes Mittel enthalten.In a further embodiment, the water-soluble packaging has two chambers. In this embodiment, the first chamber preferably contains a liquid agent and the second chamber contains a solid or a liquid agent. Alternatively, both chambers may contain a fixed average.

Weist die wasserlösliche Verpackung drei Kammern auf, können diese alle jeweils ein flüssiges oder ein festes Mittel enthalten. Möglich ist aber auch, dass eine Kammer ein festes Mittel und zwei Kammern ein flüssiges Mittel enthalten. Außerdem ist es möglich, dass in zwei Kammern ein festes Mittel und in einer Kammer ein flüssiges Mittel enthalten ist.If the water-soluble packaging has three chambers, they may each contain a liquid or a solid agent. But it is also possible that one chamber contains a solid medium and two chambers a liquid medium. In addition, it is possible for a solid agent to be contained in two chambers and a liquid agent in a chamber.

Bei wasserlöslichen Verpackungen mit vier oder mehr Kammern bestehen entsprechend noch mehr Kombinationsmöglichkeiten im Hinblick auf die Zahl der Kammern mit einem festen oder einem flüssigen Mittel.In the case of water-soluble packaging with four or more chambers, there are correspondingly more possible combinations with regard to the number of chambers with a solid or a liquid agent.

Die Mittel, die in den unterschiedlichen Kammern einer wasserlöslichen Verpackung enthalten sind, können dieselbe Zusammensetzung aufweisen. Vorzugsweise weisen die Mittel in einer wasserlöslichen Verpackung mit mindestens zwei Kammern Zusammensetzungen auf, die sich mindestens in einem Inhaltsstoff oder sich mindestens im Gehalt eines Inhaltsstoffes unterscheiden.The agents contained in the different chambers of a water-soluble package may have the same composition. Preferably, in a water-soluble package having at least two compartments, the compositions have compositions which differ in at least one ingredient or at least in content of one ingredient.

Das Mittel enthält Inhaltsstoffe, die die strukturelle Integrität der wasserlöslichen Umhüllung nicht zerstören. Ist das eingesetzte Mittel ein flüssiges oder festes Wasch- oder Reinigungsmittel kann es einen oder mehrere Stoffe aus der Gruppe der Tenside, Gerüststoffe, Bleichmittel, Bleichaktivatoren, Bleichkatalysatoren, Enzyme, Enzymstabilisatoren, Elektrolyte, pH-Stellmittel, Parfüme, Parfümträger, Fluoreszenzmittel, Farbstoffe, Hydrotope, Schauminhibitoren, Silikonöle, Antiredepositionsmittel, Vergrauungsinhibitoren, Einlaufverhinderer, Knitterschutzmittel, Farbübertragungsinhibitoren, antimikrobiellen Wirkstoffe, nicht-wässrigen Lösungsmittel, Germizide, Fungizide, Antioxidantien, Konservierungsmittel, Korrosionsinhibitoren, Antistatika, Bittermittel, Bügelhilfsmittel, Phobier- und Imprägniermittel, Trübungsmittel, Haut-pflegende Wirkstoffe, Quell-und Schiebefestmittel, weichmachenden Komponenten, Füllstoffe sowie UV-Absorber enthalten.The agent contains ingredients that do not destroy the structural integrity of the water-soluble wrapper.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert.The invention will be explained in more detail with reference to embodiments.

Zur Herstellung einer wasserlöslichen Verpackung, die eine Kammer aufweist, die mit einem flüssigen Wasch- oder Reinigungsmittel befüllt ist, wurde zunächst ein flüssiges Wasch- oder Reinigungsmittel mittels üblicher und bekannter Methoden und Verfahren hergestellt. In der folgenden Tabelle 1 ist die Zusammensetzung von einem flüssigen Wasch- oder Reinigungsmittel E1 gezeigt. Tabelle 1: Flüssiges Wasch- oder Reinigungsmittel E1 [alle Mengen sind in Gew.-% Aktivstoff, bezogen auf die Zusammensetzung, angegeben] Inhaltsstoffe E1 C10-C13-Alkylbenzolsulfonsäure 21 C13-C15-Oxo-Alkohol mit 8 EO 22,5 C12-18-Fettsäure 17,5 Glycerin 13 1,2-Propandiol 13,5 Ethanol 3,26 Phosphonat 0,3 Monoethanolamin 6,4 Farbstoffe, Enzyme (Cellulase, Amylase & Protease), optischer Aufheller, Parfüm 0,8 Wasser 1,74 To produce a water-soluble package having a chamber filled with a liquid detergent or cleaning agent, a liquid detergent or cleaning agent was first prepared by conventional methods and methods. Table 1 below shows the composition of a liquid washing or cleaning agent E1. Table 1: Liquid washing or cleaning agent E1 [all amounts are given in% by weight of active ingredient, based on the composition] ingredients E1 C 10 -C 13 -alkylbenzenesulfonic acid 21 C 13 -C 15 oxo-alcohol with 8 EO 22.5 C 12-18 fatty acid 17.5 glycerin 13 1,2-propanediol 13.5 ethanol 3.26 phosphonate 0.3 Monoethanolamine 6.4 Dyes, enzymes (cellulase, amylase & protease), optical brightener, perfume 0.8 water 1.74

Zur Herstellung einer wasserlöslichen Verpackung V1 mit dem flüssigen Wasch- oder Reinigungsmittel E1 wurde eine erste Lage einer Folie, die Polyvinylalkohol, Polymilchsäure, Saccharoseoctaactetat, 1,2-Propandiol und Glycerin enthält, mit einer Dicke von 76 µm zum Ausbilden einer Ausbuchtung mittels Vakuum in eine Mulde gezogen. Anschließend wurde die Ausbuchtung mit 30 ml des flüssigen Wasch- oder Reinigungsmittels E1 befüllt. Nach Bedecken der mit dem Mittel befüllten Ausbuchtungen mit einer zweiten Lage einer Folie, die Polyvinylalkohol, Polymilchsäure, Saccharoseoctaactetat, 1,2-Propandiol und Glycerin enthält und eine Dicke von 76 µm aufweist, wurden die erste und zweite Lage miteinander versiegelt. Die Siegelungstemperatur betrug 150 °C und die Siegelungsdauer 1,1 Sekunden. Die erste und die zweite Folienbahn enthielten jeweils Saccharoseoctaactetat in einer Verdünnung von 1 : 500.To produce a water-soluble packaging V1 with the liquid washing or cleaning agent E1, a first layer of a film containing polyvinyl alcohol, polylactic acid, sucrose octaactate, 1,2-propanediol and glycerol, with a thickness of 76 microns to form a recess by means of vacuum in pulled a hollow. Subsequently, the bulge was filled with 30 ml of the liquid detergent or cleaning agent E1. After covering the agent-filled bulges having a second layer of a film containing polyvinyl alcohol, polylactic acid, sucrose octaactate, 1,2-propanediol, and glycerin and having a thickness of 76 μm, the first and second layers were sealed together. The sealing temperature was 150 ° C and the sealing time 1.1 seconds. The first and second film webs each contained sucrose octaacetate at a 1: 500 dilution.

In einem weiteren Ausführungsbeispiel wurde eine wasserlösliche Verpackung V2 mit dem flüssigen Wasch- oder Reinigungsmittel E1 hergestellt, bei dem die Folien anstelle von Saccharoseoctaactetat Denatoniumbenzoat in einer Verdünnung von 1 : 500.000 enthielten.In a further embodiment, a water-soluble packaging V2 was prepared with the liquid washing or cleaning agent E1, in which the films instead of sucrose octaactate contained Denatoniumbenzoat in a dilution of 1: 500,000.

In beiden Fällen wurde ein schnell wahrnehmbarer, unangenehm bitterer Geschmack der eingesetzten Folien(bahnen) durch ein Panel von 10 Personen vorab bestätigt.In both cases, a fast-recognizable, unpleasantly bitter taste of the used films (webs) was confirmed in advance by a panel of 10 people.

Nach 4, 8 und 12 Wochen Lagerzeit der wasserlöslichen Verpackungen V1 und V2 unter verschiedenen klimatischen Bedingungen konnte keinerlei An- oder Auflösung der wasserlöslichen Umhüllung beobachtet werden. Zudem konnten keine Poren oder Löcher, die ebenfalls zum Produktaustritt oder Leckagen führen würden, festgestellt werden.After 4, 8 and 12 weeks storage time of the water-soluble packaging V1 and V2 under different climatic conditions, no contact or dissolution of the water-soluble coating could be observed. In addition, no pores or holes, which would also lead to product leakage or leaks, were found.

Wasserlösliche Verpackungen V1 und V2 lösten sich in Waschgängen bei Temperaturen, die im Bereich von 20 bis 95 °C lagen, rückstandslos auf.Water-soluble packaging V1 and V2 dissolved in washes at temperatures ranging from 20 to 95 ° C, without leaving residue.

Außerdem konnte bei Kontakt der beiden wasserlöslichen Verpackungen V1 und V2 mit Haut, insbesondere bei Kontakt mit trockenen oder leicht feuchten Händen, kein Übertrag der Bitterstoffe auf die Haut festgestellt werden.Moreover, when the two water-soluble packages V1 and V2 were in contact with the skin, in particular when in contact with dry or slightly moist hands, no transfer of the bitter substances to the skin could be detected.

Die Bestimmung, ob ein anhaltender und/oder störender Übertrag des Bitterstoffs vorliegt, erfolgte mit Hilfe von 10 Probanden, die eine wasserlösliche Verpackung für 5 Sekunden in der Hand fest hielten und anschließend die Hand für 5 Sekunden mit ihrer Zunge in Kontakt brachten. Bei beiden wasserlöslichen Verpackungen V1 und V2 bemerkten alle Probanden keinen oder nur maximal für 1 Minute einen leicht unangenehm bitteren Geschmack.The determination of the persistence and / or irritation of the bitter substance was made by 10 volunteers who held a water-soluble package in the hand for 5 seconds and then placed their hands in contact with their tongue for 5 seconds. In both water-soluble packaging V1 and V2 all subjects noticed no or only a maximum of 1 minute a slightly unpleasant bitter taste.
