Definitions
- 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.
- Detergents or cleaners are now available to the consumer in a variety of forms.
- this offer includes, for example, liquids, gels or sachets (tablets or filled pouches).
- 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.
- Such a water-soluble bag contains an agent and a transparent, water-soluble wrapper.
- the International Patent Publication WO 96/08555 A1 discloses a dishwashing detergent packaged in a water-soluble film wherein the water-soluble film may be coated with the bitrex® (denatonium benzoate) bitumen to prevent children from inadvertently swallowing the packaged detergent.
- bitrex® denatonium benzoate
- Denatonium benzoate is considered the bitterest known substance and has a bitter value greater than 100,000,000.
- 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.
- the object of the invention is therefore to provide water-soluble packaging with higher child safety, but without negative effects in normal use.
- a water-soluble package containing an agent and a water-soluble wrapper in which the water-soluble wrapper at least partially has a bittering agent having a bitter value between 1,000 and 200,000.
- bitter substances having these bittering values have a sufficiently high bitter taste to prevent children from keeping a water-soluble package with this bittering agent in or around the mouth, but not so bitter upon regular use of the water-soluble package the hand remaining residue of a bitter substance in case of accidental contact of the hand with the mouth irritate the taste buds of the user strongly and unpleasantly for a longer period of time.
- the invention relates to a water-soluble packaging containing an agent and a water-soluble wrapper.

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.
Die internationale Patentveröffentlichung
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 höher Kindersicherheit, aber ohne negative Effekte bei normaler Anwendung bereit zu stellen.The object of the invention is therefore to provide water-soluble packaging with higher 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 zumindest teilweise einen Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 aufweist, gelöst.This object is achieved by a water-soluble package containing an agent and a water-soluble wrapper in which the water-soluble wrapper at least partially has a bittering agent having a bitter value between 1,000 and 200,000.
Es hat sich überraschenderweise gezeigt, dass Bitterstoffe mit diesen Bitterwerten einen ausreichend hohen Bittergeschmack aufweisen, um zu verhindern dass Kinder eine wasserlösliche Verpackung mit diesem Bitterstoff weiter im oder am Mund behalten, aber bei regulärer Verwendung der wasserlöslichen Verpackung nicht so bitter sind, dass ein auf der Hand verbliebener Rest eines Bitterstoffes bei versehentlichem Kontakt der Hand mit dem Mund die Geschmacksknospen des Verwenders stark und unangenehm über einen längeren Zeitraum reizen.It has surprisingly been found that bitter substances having these bittering values have a sufficiently high bitter taste to prevent children from keeping a water-soluble package with this bittering agent in or around the mouth, but not so bitter upon regular use of the water-soluble package the hand remaining residue of a bitter substance in case of accidental contact of the hand with the mouth irritate the taste buds of the user strongly and unpleasantly for a longer period of time.

Die wasserlösliche Umhüllung weist zumindest teilweise einen Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 auf.The water-soluble wrapper has at least partially a bittering agent having a bitter value between 1,000 and 200,000.
Der Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 kann beispielsweise auf die äußere Oberfläche der wasserlöslichen Umhüllung aufgebracht oder in der wasserlöslichen Umhüllung enthalten sein.The bittering agent having a bitter value of between 1,000 and 200,000 may be applied, for example, to the outer surface of the water-soluble wrapper or contained in the water-soluble wrapper.
In einer bevorzugten Ausführungsform der Erfindung ist die äußere Oberfläche der wasserlöslichen Umhüllung zumindest teilweise mit einem Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 beschichtet. In diesem Zusammenhang ist es insbesondere zu bevorzugen, dass die wasserlösliche Umhüllung zu mindestens 50 %, vorzugsweise zu mindestens 75 % und ganz besonders bevorzugt mindestens 90 % mit dem Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 beschichtet ist.In a preferred embodiment of the invention, the outer surface of the water-soluble casing is at least partially coated with a bittering agent having a bitter value between 1,000 and 200,000. In this connection, it is particularly preferable that the water-soluble coating is coated with at least 50%, preferably at least 75%, and most preferably at least 90%, with the bittering agent having a bitter value between 1,000 and 200,000.
Das Aufbringen des Bitterstoffs mit einem Bitterwert zwischen 1.000 und 200.000 kann beispielsweise mittels Bedruckung, Besprühens oder Bestreichung erfolgen.The application of the bittering agent with a bitter value between 1,000 and 200,000, for example, by means of printing, spraying or deletion.
Grundsätzlich kann jede Form des Bedruckens zur Bedruckung der wasserlöslichen Umhüllung verwendet werden, wie beispielsweise Tiefdruck, Offsetdruck, Siebdruck, Flexodruck, Airbrush, Tintenstrahldruck oder Tampondruck oder beliebige Kombinationen dieser Drucktechnologien. Vorzugsweise erfolgt die Bedruckung mittels Tintenstrahldrucks, da bei dieser Drucktechnologie kein mechanischer Kontakt mit und somit keine mechanische Belastung der wasserlöslichen Umhüllung auftritt. Dasselbe gilt für den Direktdruck mit Piezotechnologie, da dieser auch berührungslos stattfindet.In principle, any form of printing can be used to print the water-soluble wrapper, such as gravure, offset, screen, flexo, airbrush, inkjet or pad printing, or any combination of these printing technologies. Printing by means of ink-jet printing preferably takes place since no mechanical contact with and thus no mechanical loading of the water-soluble coating occurs with this printing technology. The same applies to direct printing with piezo technology, as it also takes place without contact.
Grundsätzlich kann das Druckmedium, welches auf die wasserlösliche Umhüllung aufgebracht wird, weitere Inhaltsstoffe, wie beispielsweise eine farbgebende Substanz, enthalten.In principle, the printing medium, which is applied to the water-soluble coating, contain other ingredients, such as a coloring substance.
Alternativ kann der Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 mittels Pinsel, Rollen oder ähnlichem auf die äußere Umhüllung gestrichen werden.Alternatively, the bittering agent having a bitter value of between 1,000 and 200,000 may be painted on the outer wrapper by means of a brush, roller or the like.
In einer weiteren Alternative wird der Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 mittels eines Zerstäubers aufgesprüht.In another alternative, the bittering agent is sprayed with a bitter value between 1,000 and 200,000 by means of an atomizer.
Das Aufbringen des Bitterstoffes mit einem Bitterwert zwischen 1.000 und 200.000 kann in Form von Flächen erfolgen, so dass die wasserlösliche Umhüllung zumindest teilweise flächendeckend mit einem Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 bedeckt ist. Alternativ kann das Aufbringen des Bitterstoffes mit einem Bitterwert zwischen 1.000 und 200.000 in Form von Buchstaben, Zahlen, Symbolen, Ornamenten oder ähnlichem erfolgen. Letzteres ist insbesondere bevorzugt, wenn der Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 mittels Druckens aufgebracht wird und das Druckmedium neben dem Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 eine farbgebende Substanz enthält.The application of the bittering agent with a bitter value between 1,000 and 200,000 may take place in the form of surfaces, so that the water-soluble coating is at least partially covered with a bitter substance having a bitter value between 1,000 and 200,000. Alternatively, the application of the bittering agent having a bitter value between 1,000 and 200,000 may be in the form of letters, numbers, symbols, ornaments or the like. The latter is particularly preferable when the bitter substance having a bitter value between 1,000 and 200,000 is applied by means of printing, and the printing medium contains a coloring matter in addition to the bitter substance having a bitter value between 1,000 and 200,000.
Alternativ zum Aufbringen auf die äußere Oberfläche der wasserlöslichen Umhüllung kann der Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 in das Folienmaterial der wasserlöslichen Umhüllung eingebracht werden.Alternatively, for application to the outer surface of the water-soluble wrapper, the bittering agent having a bitter value of between 1,000 and 200,000 may be incorporated in the film material of the water-soluble wrapper.
Als Bitterstoffe werden alle chemischen Verbindungen bezeichnet, die einen bitteren Geschmack aufweisen.Bitter substances are all chemical compounds that have a bitter taste.
Der Bitterstoff weist einen Bitterwert zwischen 1.000 und 200.000 auf. Der Bitterwert ist der Kehrwert jener Verdünnung eines Stoffes, einer Flüssigkeit oder eines Extraktes, die eben noch bitter schmeckt.The bitter substance has a bitter value between 1,000 and 200,000. 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.The standardized method described in the European Pharmacopoeia (5th Edition, Grundwerk, Stuttgart 2005, Volume 1 General Part Monograph Groups, 2.8.15 Bitter Value, p. 278) is used to determine the bitterness value.
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 zwischen 1.000 und 200.000, welche in dem Folienmaterial zur Herstellung der wasserlöslichen Umhüllung enthalten oder auf der äußeren Oberfläche der wasserlöslichen Umhüllung aufgebracht sein können, sind vorzugsweise natürliche Bitterstoffe mit einem Bitterwert zwischen 1.000 und 200.000. Insbesondere bevorzugt sind die natürlichen Bitterstoffe mit einem Bitterwert zwischen 1.000 und 200.000 ausgewählt aus der Gruppe bestehend aus Glycosiden, Isoprenoiden, Alkaloiden, Aminosäuren und Mischungen daraus.Suitable bitter substances having a bitter value of between 1,000 and 200,000, which may be contained in the film material for producing the water-soluble casing or may be applied on the outer surface of the water-soluble casing, are preferably natural bitter substances having a bitter value of between 1,000 and 200,000. Particularly preferred are the natural bittering agents with a bitter value between 1,000 and 200,000 selected from the Group consisting of glycosides, isoprenoids, alkaloids, amino acids and mixtures thereof.
Glycoside sind organische Verbindungen der allgemeinen Struktur R-O-Z, bei denen ein Alkohol (R-OH) über eine glycosidische Bindung mit einem Zuckerteil (Z) verbunden ist.Glycosides are organic compounds of the general structure R-O-Z, in which an alcohol (R-OH) is connected via a glycosidic bond with a sugar moiety (Z).

Isoprenoide sind Verbindungen, die sich formal von Isopren ableiten. Beispiele sind insbesondere Terpene und Terpenoide.Isoprenoids are compounds that formally derive from isoprene. Examples are in particular terpenes and terpenoids.
Geeignete Isoprenoide umfassen beispielsweise Sequiterpenlactone wie Absinthin, Artabsin, Cnicin, Lactucin, Lactucopikrin oder Salonitenolid, Monoterpen-Ketone (Thujone) wie beispielsweise α-Thujon oder β-Thujon, Tetranortriterpene (Limonoide) wie Desoxylimonen, Desoxylimonensäure, Limonin, Ichangin, Iso-Obacunonsäure, Obacunon, Obacunonsäure, Nomilin oder Nomilinsäure, Terpene wie Marrubin, Prämarrubin, Carnosol, Carnosolsäure oder Quassin.Suitable isoprenoids include, for example, sequiterpene lactones such as absinthine, artabsine, cnicine, lactucin, lactucopirrin or salzolidideolide, monoterpene ketones (thujones) such as α-thujone or β-thujone, tetranortriterpenes (limonoids) such as desoxylimones, deoxylmonic acid, limonin, ichangine, iso-obacunonic acid , Obacunone, obacunonic acid, nomiline or nomilinic acid, terpenes such as marrubin, premarubin, carnosol, carnosic acid or quassin.
Alkaloide bezeichnen natürlich vorkommende, chemisch heterogene, meist alkalische, stickstoffhaltige organische Verbindungen des Sekundärstoffwechsels, die auf den tierischen oder menschlichen Organismus wirken.Alkaloids refer to naturally occurring, chemically heterogeneous, mostly alkaline, nitrogen-containing organic compounds of secondary metabolism which act on the animal or human organism.
Geeignete Alkaloide sind beispielsweise Chininhydrochlorid, Chininhydrogensulfat, Chinindihydrochlorid, Chininsulfat, Columbin und Coffein.Suitable alkaloids are, for example, quinine hydrochloride, quinine hydrogen sulfate, quinine dihydrochloride, quinine sulfate, columbine and caffeine.

Besonders bevorzugte Bitterstoffe mit einem Bitterwert zwischen 1.000 und 200.000 sind Chininsulfat (Bitterwert = 10.000), Naringin (Bitterwert = 10.000), Saccharoseoctaacetat (Bitterwert = 100.000), Chininhydrochlorid und Mischungen daraus.Particularly preferred bitter substances having a bitter value between 1,000 and 200,000 are quinine sulfate (bitter value = 10,000), naringin (bitter value = 10,000), sucrose octaacetate (bitter value = 100,000), quinine hydrochloride and mixtures thereof.
Die Verwendung einer Mischung von Bitterstoffen kann vorteilhaft sein, da Menschen eine unterschiedliche Anzahl von Geschmackszellen auf der Zunge aufweisen. Neben sogenannten Superschmeckern und Normalschmeckern gibt es auch so genannte Nichtschmecker, die einzelne Bitterstoffe gar nicht oder geringfügig schmecken. Durch Verwendung einer Mischung aus mindestens zwei Bitterstoffen mit einem Bitterwert zwischen 1.000 und 200.000 kann das Risiko, dass der abschreckend wirken sollende Bitterstoff gar nicht geschmeckt wird, reduziert werden. Die Menge an Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 hängt insbesondere von der gewünschten Intensität des Bittergeschmacks ab. Ist der Bitterstoff in der wasserlöslichen Umhüllung enthalten, beträgt die Menge an Bitterstoff zwischen 1 und 30 g pro m2 Oberfläche der wasserlöslichen Umhüllung. Ist der Bitterstoff auf der äußeren Oberfläche der wasserlöslichen Umhüllung aufgebracht, beträgt die Menge an Bitterstoff zwischen 1 und 30 g pro m2 beschichteter Oberfläche der wasserlöslichen Umhüllung.The use of a mixture of bitter substances may be advantageous because humans have a different number of taste cells on the tongue. In addition to so-called super-tasters and normal gourmets, there are also so-called non-gourmets, the individual bitter substances do not taste or slightly. By using a mixture of at least two bittering agents with a bitter value between 1,000 and 200,000, the risk of the bittering agent acting as a deterrent being not tasted at all can be reduced. The amount of bittering agent having a bitter value between 1,000 and 200,000 depends in particular on the desired intensity of the bitter taste. If the bittering agent is contained in the water-soluble coating, the amount of bittering agent is between 1 and 30 g per m 2 surface of the water-soluble coating. When the bittering agent is applied to the outer surface of the water-soluble wrapper, the amount of the bittering agent is from 1 to 30 g per m 2 of the coated surface of the water-soluble wrapper.

Zur Herstellung einer wasserlöslichen Umhüllung, die zumindest teilweise einen Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 enthält, wird dem Folienmaterial der Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 zugesetzt.For producing a water-soluble wrapper containing at least partially a bittering agent having a bitter value between 1,000 and 200,000, the bittering agent having a bitter value between 1,000 and 200,000 is added to the film material.
Dies kann beispielsweise geschehen, in dem (a) ein wasserlösliches Polymer, welches vorzugsweise Polyvinylalkohol oder ein Polyvinylalkoholcopolymer enthält, alleine oder in Kombination mit wenigstens einem weiteren wasserlöslichen Polymer, einem Lösungsmittel, dem Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 und gegebenenfalls weiteren Zusatzstoffen zu einer Matrix kombiniert wird, (b) ein Film aus der Matrix gebildet wird und (c) der Film zu einer zumindest teilweise einen Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 aufweisenden wasserlöslichen Folie getrocknet wird.This can be done, for example, in which (a) a water-soluble polymer, which preferably contains polyvinyl alcohol or a polyvinyl alcohol copolymer, alone or in combination with at least one further water-soluble polymer, a solvent, the bittering agent having a bitter value between 1,000 and 200,000 and optionally further additives a matrix is combined, (b) a film is formed from the matrix, and (c) the film is dried to a water-soluble film having, at least in part, a bitter substance having a bitterness value between 1,000 and 200,000.
Die Bildung des Films kann beispielsweise mittels Gießen und Gegenlaufwalzenstreichens erfolgen.The formation of the film can be done, for example, by means of casting and Gegenlaufwalzenstreichens.
Alternativ kann eine zumindest teilweise einen Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 aufweisende Folie erhalten werden, in dem (a) ein wasserlösliches Polymer, welches vorzugsweise Polyvinylalkohol oder ein Polyvinylalkoholcopolymer enthält, alleine oder in Kombination mit wenigstens einem weiteren wasserlöslichen Polymer, einem Lösungsmittel, dem Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 und gegebenenfalls weiteren Zusatzstoffen zu einer Matrix kombiniert wird und (b) mittels Extrusion der Matrix eine zumindest teilweise einen Bitterstoff mit einem Bitterwert zwischen 1.000 und 200.000 aufweisende wasserlösliche Folie erhalten wird.Alternatively, a film at least partially having a bittering value of between 1,000 and 200,000 may be obtained, in which (a) a water-soluble polymer, preferably containing polyvinyl alcohol or a polyvinyl alcohol copolymer, alone or in combination with at least one other water-soluble polymer, a solvent, the bitter substance having a bitter value between 1,000 and 200,000 and optionally further additives is combined into a matrix; and (b) by extrusion of the matrix, a water-soluble film having, at least partially, a bitter substance having a bitter value of between 1,000 and 200,000 is obtained.
Die Erfindung wird nachfolgend anhand von zwei Ausführungsbeispielen näher erläutert.The invention will be explained in more detail with reference to two 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.
Zur Herstellung einer wasserlöslichen Verpackung mit dem flüssigen Wasch- oder Reinigungsmittel E1 wurde eine Folie vom Typ M 8630 (ex Monosol) 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,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.To produce a water-soluble package with the liquid detergent or cleaning agent E1, a film of the type M 8630 (ex Monosol) having a thickness of 76 μm was pulled into a depression by means of a vacuum to form a bulge. Subsequently, the bulge was filled with 30 ml of the liquid detergent or cleaning agent E1. After covering the agent-filled protrusions with a second layer of a film containing polyvinyl alcohol, polylactic acid, 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.
Anschließend wurde die gesamte äußere Oberfläche der wasserlöslichen Verpackung auf beiden Seiten mittels eines Zerstäubers mit einem Saccharoseoctaacetat-haltigen, wäßrigen Medium gleichmäßig besprüht. Die Menge an Saccharoseoctaacetat pro wasserlöslicher Verpackung betrug 2000 ppm. Die Flüssigkeit wurde innerhalb von 5 Sekunden von der wasserlöslichen Umhüllung absorbiert.Subsequently, the entire outer surface of the water-soluble package was uniformly sprayed on both sides by means of a nebulizer with a sucrose octaacetate-containing aqueous medium. The amount of sucrose octaacetate per water-soluble package was 2000 ppm. The liquid was absorbed within 5 seconds by the water-soluble coating.
Zur Herstellung einer wasserlöslichen Verpackung V2 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 Menge von 2000 ppm.To produce a water-soluble packaging V2 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 with a second layer of a film containing polyvinyl alcohol, polylactic acid, sucrose octaactate, 1,2-propanediol, and glycerol 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 in an amount of 2000 ppm.
In beiden Fällen wurde ein schnell wahrnehmbarer, unangenehm bitterer Geschmack der wasserlöslichen Umhüllung durch ein Panel von 10 Personen bestätigt.In both cases, a fast-recognizable, unpleasantly bitter taste of the water-soluble coating was confirmed by a panel of 10 persons.
Nach 4, 8 und 12 Wochen Lagerzeit der wasserlöslichen Verpackungen V1 und V2 mit dem Wasch- oder Reinigungsmittel E1 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 with the washing or cleaning agent E1 under different climatic conditions, no arrival 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 mit dem Wasch- oder Reinigungsmitteln E1 lösten sich in Waschgängen bei Temperaturen, die im Bereich von 20 bis 95 °C lagen, rückstandslos auf.Water-soluble packaging V1 and V2 with the washing or cleaning agent E1 dissolved in washes at temperatures ranging from 20 to 95 ° C, leaving no residue.
Außerdem konnte bei Kontakt der wasserlöslichen Verpackung mit Haut, insbesondere bei Kontakt mit trockenen oder leicht feuchten Händen, kein anhaltender und/oder störender Übertrag der Bitterstoffe auf die Haut festgestellt werden.In addition, contact of the water-soluble packaging with skin, especially when in contact with dry or slightly moist hands, no lasting and / or disturbing carry over the bitterness of the skin could be found.
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.
