Definitions

  • the present invention relates to a method for printing water-soluble or water-dispersible film bags which contain a detergent or cleaning agent.
  • Detergents and cleaning agents such as dishwashing detergents
  • dishwashing detergents are available to consumers in a variety of forms.
  • flowable and in particular liquid to gel-like agents have become increasingly important in recent years.
  • the consumer appreciates the quick solubility and the associated rapid availability of the ingredients in the washing and cleaning liquor, especially in short washing and dishwashing programs and at low temperatures.
  • the water-soluble covering is usually formed from a water-soluble or water-dispersible film material, in particular consisting of polymers or polymer mixtures.
  • the covering can consist of one or two or more layers of water-soluble or water-dispersible film material.
  • films are often used which can be glued and / or sealed to packaging such as hoses or pillows after they have been filled with an agent.
  • the water-soluble or water-dispersible coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer, since such coatings have good stability with a sufficiently high water solubility, in particular cold water solubility.
  • Liquid detergents and cleaning agents are currently offered in water-soluble film bags, the individual film bags containing single servings being offered in an outer packaging which contains a large number of film bags. While the outer packaging application and hazardous substance notices, as well as product names, manufacturers, etc. identifies, a single foil bag does not provide the user with this information. It is known to print the water-soluble film of such a film bag before shaping (thermoforming; deep-drawing), as is the case, for example, in the international patent publications WO 2010/135238 A1 and WO 2009/063355 A1 as well as the U.S. Patent 5,666,785 A1 described. The final print image is but whether the subsequent deep-drawing is difficult to influence and often distorted or warped. Another possibility is the use of labels, which can be glued to the foil bag, but this is associated with additional costs and complex production techniques.
  • the WO 2010/0135238 A1 discloses a comparable rubber printing process (flexography printing) for water-soluble films, which is immediately upstream of a downstream manufacturing process for detergent bags.
  • flexography printing a comparable rubber printing process for water-soluble films
  • the WO 2008/004199 A2 finally describes water-soluble bags filled with detergents or cleaning agents, the bags being provided with an optical, tactile and / or audible indicator.
  • a label can be applied to the bag in various ways on the one hand and can optionally be applied to the bag film before or after the bag production.
  • process alternatives for generating the bag identification there including printing processes such as the pad printing process.
  • procedural instructions there are only general and therefore abstract in nature.
  • the invention therefore relates to a method for printing a pouch filled with a detergent or cleaning agent from a water-soluble or water-dispersible film with an imprint, characterized in that the pouch is printed by means of a pad printing process.
  • the invention is directed to the bags made of a water-soluble or water-dispersible film, which are produced, printed and filled with a washing or cleaning agent by means of the method according to the invention.
  • Pad printing processes are known in the prior art.
  • Pad printing is an indirect gravure printing process in which the printing ink is transferred from the printing form to the printing material by means of an elastic tampon, usually made of silicone rubber.
  • the printed image to be transferred is normally exposed on a cliché using a positive film (offset film).
  • This cliché is then washed out, the exposed printed image remaining in a recessed manner on the surface of the cliché.
  • the cliché can consist of a wide variety of materials, for example a distinction is made between steel and plastic clichés. Alternatively, the cliché can also consist of zinc or copper.
  • the printing ink is usually washed over the cliché using a metal or plastic squeegee and removed using a squeegee or a knife, the ink remaining in the recess.
  • the tampon then attaches to this printing form, lifts off again with the printing ink and moves to the printing material. There the tampon lowers, adapts to the shape and leaves the color (the printed image) on the print material. Since the tampon itself is elastically deformable and can take on the shape of the body to be printed, this method enables printing on curved surfaces (convex, concave or irregular) without distorting or distorting the printed image.
  • the ink transfer to the substrate is up to 100%.

  • the tampon consists of silicone rubber and is elastic.
  • the bag is fixed in a holder in order to avoid slipping during the printing process.
  • the holder can have a shape that is adapted to the shape of the film bag.
  • the holder can have a concave depression which corresponds to the convex surface of the bag.
  • the lower part of the mold already used for molding (thermoforming; deep drawing) and / or filling the bag can also serve as such a holder.
  • the inks or color inks used for printing are chosen so that they are compatible with the material of the foil pouch, i.e. in particular, this does not dissolve or react in any other way with it and impair its structural integrity. It is furthermore provided that the color inks are water-soluble and preferably dissolve in water without residue. Furthermore, when using the washing or cleaning agent, they should not cause any residues or discolouration on the objects to be washed or cleaned.
  • the printing inks / color inks can have any suitable viscosity which enables printing in the pad printing process.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Bedrucken von wasserlöslichen oder wasserdispergierbaren Folienbeuteln, die ein Wasch- oder Reinigungsmittel enthalten.The present invention relates to a method for printing water-soluble or water-dispersible film bags which contain a detergent or cleaning agent.

Wasch- und Reinigungsmittel, wie beispielsweise Geschirrspülmittel, stehen dem Verbraucher in einer Vielzahl von Angebotsformen zur Verfügung. Neben den traditionellen festen Mitteln haben in den letzten Jahren zunehmend fließfähige und insbesondere flüssige bis gelförmige Mittel an Bedeutung gewonnen. Der Verbraucher schätzt vor allem die schnelle Löslichkeit und die damit einhergehende schnelle Verfügbarkeit der Inhaltsstoffe in der Wasch- und Reinigungsflotte insbesondere auch in Kurzwasch- und -geschirrspülprogrammen und bei niedrigen Temperaturen.Detergents and cleaning agents, such as dishwashing detergents, are available to consumers in a variety of forms. In addition to traditional solid agents, flowable and in particular liquid to gel-like agents have become increasingly important in recent years. Above all, the consumer appreciates the quick solubility and the associated rapid availability of the ingredients in the washing and cleaning liquor, especially in short washing and dishwashing programs and at low temperatures.

Ferner haben sich die Verbraucher an ein bequemes Dosieren von vorportionierten Waschmitteln und maschinellen Geschirrspülmitteln gewöhnt. Um ein flüssiges Wasch- oder Geschirrspülmittel, das die oben erwähnten Vorteile gegenüber festen Zusammensetzungen bietet, in eine vorportionierte Angebotsform zu bringen, ist die Verwendung von kaltwasserlöslichen Folien in der Form von Beuteln üblich. Das Wasch- oder Reinigungsmittel kann dabei derart konfektioniert sein, dass Einmalportionen jeweils separat verpackt sind.Furthermore, consumers have become accustomed to convenient dosing of pre-portioned detergents and machine dishwashing detergents. In order to bring a liquid detergent or dishwashing detergent, which offers the above-mentioned advantages over solid compositions, into a pre-portioned supply form, the use of cold water-soluble films in the form of bags is common. The washing or cleaning agent can be made up in such a way that single servings are each packed separately.

Die wasserlösliche Umhüllung wird üblicherweise aus einem wasserlöslichen oder wasserdispergierbaren Folienmaterial, insbesondere bestehend aus Polymeren oder Polymergemischen, gebildet. Die Umhüllung kann aus einer oder aus zwei oder mehr Lagen wasserlöslichen oder wasserdispergierbaren Folienmaterials bestehen. Häufig werden beispielsweise Folien verwendet, die zu Verpackungen wie Schläuchen oder Kissen verklebt und/oder versiegelt werden können, nachdem sie mit einem Mittel befüllt wurden.The water-soluble covering is usually formed from a water-soluble or water-dispersible film material, in particular consisting of polymers or polymer mixtures. The covering can consist of one or two or more layers of water-soluble or water-dispersible film material. For example, films are often used which can be glued and / or sealed to packaging such as hoses or pillows after they have been filled with an agent.

In vielen Produkten enthält die wasserlösliche oder wassersdispergierbare Umhüllung Polyvinylalkohol oder ein Polyvinylalkoholcopolymer, da derartige Umhüllungen eine gute Stabilität bei einer ausreichend hohen Wasserlöslichkeit, insbesondere Kaltwasserlöslichkeit, aufweisen.In many products, the water-soluble or water-dispersible coating contains polyvinyl alcohol or a polyvinyl alcohol copolymer, since such coatings have good stability with a sufficiently high water solubility, in particular cold water solubility.

Derzeit werden flüssige Wasch- und Reinigungsmittel in wasserlöslichen Folienbeuteln angeboten, wobei die einzelnen Folienbeutel, die Einmalportionen enthalten, in einer Umverpackung, die eine Vielzahl von Folienbeuteln enthält, angeboten werden. Während die Umverpackung Anwendungs- und Gefahrstoffhinweise, sowie Produktnamen, Hersteller, u.ä. ausweist, stellt ein einzelner Folienbeutel dem Anwender diese Informationen nicht zur Verfügung. Es ist bekannt, die wasserlösliche Folie eines solchen Folienbeutels vor dem Formen (Thermoformen; Tiefziehen) zu bedrucken, wie beispielsweise in den internationalen Patentveröffentlichungen WO 2010/135238 A1 und WO 2009/063355 A1 sowie der US Patentschrift 5,666,785 A1 beschrieben. Das finale Druckbild ist aber ob des anschließenden Tiefziehens nur schwerlich beeinflussbar und oftmals verzerrt oder verzogen. Eine weitere Möglichkeit ist die Verwendung von Etiketten, welche auf den Folienbeutel geklebt werden können, was allerdings mit zusätzlichen Kosten und aufwendigen Produktionstechniken verbunden ist.Liquid detergents and cleaning agents are currently offered in water-soluble film bags, the individual film bags containing single servings being offered in an outer packaging which contains a large number of film bags. While the outer packaging application and hazardous substance notices, as well as product names, manufacturers, etc. identifies, a single foil bag does not provide the user with this information. It is known to print the water-soluble film of such a film bag before shaping (thermoforming; deep-drawing), as is the case, for example, in the international patent publications WO 2010/135238 A1 and WO 2009/063355 A1 as well as the U.S. Patent 5,666,785 A1 described. The final print image is but whether the subsequent deep-drawing is difficult to influence and often distorted or warped. Another possibility is the use of labels, which can be glued to the foil bag, but this is associated with additional costs and complex production techniques.

So beschreibt die Youtube-Internetveröffentlicheung "Pouch Pneumatic Pad Printing Machine" (www.youtube.com/watch?v=mvGsuu_SZbs) die grundsätzliche Anwendung eines Tampondruckverfahrens bei wasserunlöslichen Umverpackungsbeuteln zu deren Kennzeichnung. Dabei wird lediglich ein halbautomatisiertes Druckverfahren offenbart, welches noch immer einen unerwünscht hohen manuellen Arbeitsanteil aufweist.The YouTube Internet publication "Pouch Pneumatic Pad Printing Machine" (www.youtube.com/watch?v=mvGsuu_SZbs) describes the basic application of a pad printing process for water-insoluble outer packaging bags to label them. Only a semi-automated printing process is disclosed, which still has an undesirably high amount of manual work.

Aus der WO 2009/063355 A1 ist ein Gummidruckverfahren (flexography printing) für wasserlösliche Folien zur späteren Erstellung von wasserlöslichen Beuteln bekannt. Hier ergibt sich eine grundsätzliche Schwierigkeit das Druckbild auf der Folie im Hinblick auf die spätere Beutelgeometrie passgenau zu positionieren.From the WO 2009/063355 A1 is known a rubber printing process (flexography printing) for water-soluble films for the later creation of water-soluble bags. There is a fundamental difficulty here in positioning the print image on the film with a view to the later bag geometry.

Die WO 2010/0135238 A1 offenbart ein vergleichbares Gummidruckverfahren (flexography printing) für wasserlösliche Folien, welches unmittelbar einem nachgelagerten Herstellprozess für Waschmittelbeutel vorgeschaltet ist. Auch hier ergeben sich die bereits erwähnten Schwierigkeiten der exakten Druckbildpositionierung auf dem finalen Waschmittelbeutel.The WO 2010/0135238 A1 discloses a comparable rubber printing process (flexography printing) for water-soluble films, which is immediately upstream of a downstream manufacturing process for detergent bags. Here, too, the difficulties already mentioned of exact positioning of the printed image on the final detergent pouch arise.

Darüber hinaus ist der WO 2007/034471 A1 die Bedruckung eines Films, der selbst Reinigungsmittel enthalten kann, mit einer Grafik zu entnehmen.In addition, the WO 2007/034471 A1 the graphic of a film that can itself contain cleaning agents.

Die WO 2008/004199 A2 beschreibt schließlich wasserlösliche Beutel gefüllt mit Wasch- oder Reinigungsmittel, wobei die Beutel mit einem optischen, fühlbaren und/oder hörbaren Kennzeichen versehen sind. Ein solches Kennzeichen kann einerseits auf unterschiedlichstem Wege auf den Beutel aufgebracht werden und andererseits optional vor oder nach der Beutelherstellung auf die Beutelfolie aufgebracht werden. Darüber hinaus werden dort auch eine Vielzahl unterschiedlicher Verfahrensalternativen zur Erzeugung der dortigen Beutelkennzeichnung, u. a. auch Druckverfahren, wie das Tampondruckverfahren erwähnt. Allerdings sind die dortigen Verfahrensanweisungen ledigliech allgemeiner und somit abstrakter Natur.The WO 2008/004199 A2 finally describes water-soluble bags filled with detergents or cleaning agents, the bags being provided with an optical, tactile and / or audible indicator. Such a label can be applied to the bag in various ways on the one hand and can optionally be applied to the bag film before or after the bag production. In addition, there are also a variety of different process alternatives for generating the bag identification there, including printing processes such as the pad printing process. However, the procedural instructions there are only general and therefore abstract in nature.

Aufgabe der vorliegenden Erfindung war es daher, eine verbesserte Möglichkeit zur Informationspräsentation auf wasserlöslichen oder wasserdispergierbaren Folienbeuteln, die Wasch- oder Reinigungsmittel enthalten, bereitzustellen.It was therefore an object of the present invention to provide an improved possibility for presenting information on water-soluble or water-dispersible film bags which contain detergents or cleaning agents.

Diese Aufgabe wird gemäß der vorliegenden Erfindung dadurch gelöst, dass die gefüllten, fertigen Folienbeutel in einem erfindungsgemäßen Tampondruckverfahren bedruckt werden. In einem ersten Aspekt betrifft die Erfindung daher ein Verfahren zum Bedrucken eines mit einem Wasch- oder Reinigungsmittel gefüllten Beutels aus einer wasserlöslichen oder wasserdispergierbaren Folie mit einem Aufdruck, dadurch gekennzeichnet, dass das Bedrucken des Beutels mittels eines Tampondruckverfahrens erfolgt.According to the present invention, this object is achieved in that the filled, finished Foil bags are printed in a pad printing process according to the invention. In a first aspect, the invention therefore relates to a method for printing a pouch filled with a detergent or cleaning agent from a water-soluble or water-dispersible film with an imprint, characterized in that the pouch is printed by means of a pad printing process.

In einem weiteren Aspekt richtet sich die Erfindung auf die mittels des erfindungsgemäßen Verfahrens hergestellten, bedruckten, mit einem Wasch- oder Reinigungsmittel gefüllten Beutel aus einer wasserlöslichen oder wasserdispergierbaren Folie.In a further aspect, the invention is directed to the bags made of a water-soluble or water-dispersible film, which are produced, printed and filled with a washing or cleaning agent by means of the method according to the invention.

Tampondruckverfahren sind im Stand der Technik bekannt. Der Tampondruck ist ein indirektes Tiefdruckverfahren, bei dem die Druckfarbe durch einen elastischen Tampon, üblicherweise aus Silikonkautschuk, von der Druckform auf den Bedruckstoff übertragen wird. Bei diesem Druckverfahren wird normalerweise das Druckbild, das übertragen werden soll, mit einem Positiv-Film (Offsetfilm) auf ein Klischee belichtet. Dieses Klischee wird dann ausgewaschen, wobei das belichtete Druckbild vertieft auf der Oberfläche des Klischees zurückbleibt. Das Klischee kann aus den verschiedensten Materialien bestehen, so unterscheidet man zum Beispiel Stahlklischees und Kunststoffklischees. Alternativ kann das Klischee auch aus Zink oder Kupfer bestehen.Pad printing processes are known in the prior art. Pad printing is an indirect gravure printing process in which the printing ink is transferred from the printing form to the printing material by means of an elastic tampon, usually made of silicone rubber. In this printing process, the printed image to be transferred is normally exposed on a cliché using a positive film (offset film). This cliché is then washed out, the exposed printed image remaining in a recessed manner on the surface of the cliché. The cliché can consist of a wide variety of materials, for example a distinction is made between steel and plastic clichés. Alternatively, the cliché can also consist of zinc or copper.

Beim Druckvorgang wird normalerweise die Druckfarbe mit Hilfe einer Rakel aus Metall oder Kunststoff über das Klischee geschwemmt und mit der Rakel oder einem Messer abgezogen, wobei die Farbe in der Vertiefung zurückbleibt. Anschließend setzt der Tampon auf diese Druckform auf, hebt unter Mitnahme von Druckfarbe wieder ab und fährt zum Bedruckstoff. Dort senkt sich der Tampon, passt sich der Form an und hinterlässt die Farbe (das Druckbild) auf dem Druckgut. Da der Tampon selbst elastisch verformbar ist und die Form des zu bedruckenden Körpers annehmen kann, wird mit diesem Verfahren das Bedrucken von gewölbten Flächen (konvex, konkav oder unregelmäßig) möglich ohne dass das Druckbild verzerrt oder verzogen wird. Je nach Material des Tampons oder der Art der Farbe liegt die Farbübertragung auf den Bedruckstoff bei bis zu 100 %.During the printing process, the printing ink is usually washed over the cliché using a metal or plastic squeegee and removed using a squeegee or a knife, the ink remaining in the recess. The tampon then attaches to this printing form, lifts off again with the printing ink and moves to the printing material. There the tampon lowers, adapts to the shape and leaves the color (the printed image) on the print material. Since the tampon itself is elastically deformable and can take on the shape of the body to be printed, this method enables printing on curved surfaces (convex, concave or irregular) without distorting or distorting the printed image. Depending on the material of the tampon or the type of color, the ink transfer to the substrate is up to 100%.

In verschiedenen Ausführungsformen der Erfindung, hat der Tampon, der zum Bedrucken der Folienbeutel verwendet wird, eine Härte, die so gewählt ist, dass er sich der Form des Beutels anpasst und ein guter Kontakt zwischen Tamponoberfläche und Beuteloberfläche hergestellt wird ohne dass der Beutel beschädigt wird. So kann der Tampon vorzugsweise eine Shore-A Härte im Bereich von 0-20 aufweisen, vorzugsweise von 0-15, insbesondere von ungefähr 5. In verschiedenen Ausführungsformen besteht der Tampon aus Silikonkautschuk und ist elastisch.In various embodiments of the invention, the tampon used for printing on the film bags has a hardness which is selected such that it adapts to the shape of the bag and good contact is made between the tampon surface and the bag surface without the bag being damaged . For example, the tampon can preferably have a Shore-A hardness in the range from 0-20, preferably from 0-15, in particular approximately 5. In various embodiments, the tampon consists of silicone rubber and is elastic.

Das erfindungsgemäße Verfahren umfasst, in verschiedenen Ausführungsformen der Erfindung, die folgende Schritte:

  1. (i) Aufbringen einer Tinte oder eines Mediums, die/das eine farbgebende Substanz enthält, auf ein Klischee;
  2. (ii) Abstreichen überschüssiger Tinte oder überschüssigen Mediums mittels eines Rakels;
  3. (iii) Aufdrücken des Tampons auf das Klischee, wobei die Tinte oder das Medium von dem Klischee auf das Tampon übertragen wird; und
  4. (iv) Aufdrücken des Tampons auf den Beutel, wobei die Tinte oder das Medium von dem Tampon auf den Beutel übertragen wird.
In various embodiments of the invention, the method according to the invention comprises the following steps:
  1. (i) applying an ink or medium containing a colorant to a cliché;
  2. (ii) wiping off excess ink or media using a squeegee;
  3. (iii) pressing the tampon onto the plate, the ink or medium being transferred from the plate to the tampon; and
  4. (iv) pressing the tampon onto the pouch, transferring the ink or medium from the tampon to the pouch.

In dem erfindungsgemäßen Verfahren ist der Beutel in einer Halterung fixiert, um ein Verrutschen während des Druckvorgangs zu vermeiden. Dabei kann die Halterung eine Form aufweisen, die der Form des Folienbeutels angepasst ist. Beispielsweise kann die Halterung eine konkave Vertiefung aufweisen, die der konvexen Oberfläche des Beutels entspricht. Als eine solche Halterung kann beispielsweise auch das Unterteil der bereits zum Formen (Thermoformen; Tiefziehen) und/oder Befüllen des Beutels verwendeten Form dienen.In the method according to the invention, the bag is fixed in a holder in order to avoid slipping during the printing process. The holder can have a shape that is adapted to the shape of the film bag. For example, the holder can have a concave depression which corresponds to the convex surface of the bag. The lower part of the mold already used for molding (thermoforming; deep drawing) and / or filling the bag can also serve as such a holder.

Die Druckfarben oder Farbtinten die zum Bedrucken verwendet werden, sind derart gewählt, dass sie mit dem Material des Folienbeutels kompatibel sind, d.h. insbesondere dieses weder Auflösen noch in anderer Weise mit ihm reagieren und dessen strukturelle Integrität beeinträchtigen. Es ist weiterhin vorgesehen, dass die Farbtinten wasserlöslich sind und sich vorzugsweise rückstandsfrei in Wasser auflösen. Ferner sollten sie beim Einsatz des Wasch- oder Reinigungsmittels auf den zu waschenden oder reinigenden Gegenständen keine Rückstände oder Verfärbungen hervorrufen. Die Druckfarben/Farbtinten können jede geeignete Viskosität aufweisen, die ein Bedrucken im Tampondruckverfahren ermöglicht. Geeignete Tinten sind beispielsweise unter dem Handelsnamen SunChemical Aquadestruct (Sun Chemical, NJ, USA), Aqua Poly Super Opaque White QW000046 der Fa. Environmental Inks oder Opta Film OPQ White W0L009656 der Fa. Water Ink Technologies Inc. erhältlich.The inks or color inks used for printing are chosen so that they are compatible with the material of the foil pouch, i.e. in particular, this does not dissolve or react in any other way with it and impair its structural integrity. It is furthermore provided that the color inks are water-soluble and preferably dissolve in water without residue. Furthermore, when using the washing or cleaning agent, they should not cause any residues or discolouration on the objects to be washed or cleaned. The printing inks / color inks can have any suitable viscosity which enables printing in the pad printing process. Suitable inks are available, for example, under the trade name Sun Chemical Aquadestruct (Sun Chemical, NJ, USA), Aqua Poly Super Opaque White QW000046 from Environmental Inks or Opta Film OPQ White W0L009656 from Water Ink Technologies Inc.

In bestimmten Ausführungsformen des Verfahrens können die Schritte (i) bis (iv) mehrmals, vorzugsweise 1- bis 3-mal wiederholt werden. Dabei werden vorzugsweise andere Tinten oder Medien, die eine farbgebende Substanz enthalten, verwendet, so dass auch mehrfarbige Aufdrucke möglich sind. Die Wiederholungen der Schritte (i) bis (iv) können jeweils in separaten Druckeinheiten, die in einem kontinuierlichen Verfahren hintereinander angeordnet sein können, durchgeführt werden.In certain embodiments of the method, steps (i) to (iv) can be repeated a number of times, preferably 1 to 3 times. Other inks or media containing a coloring substance are preferably used, so that multi-colored prints are also possible. The repetitions of steps (i) to (iv) can each be carried out in separate printing units which can be arranged one after the other in a continuous process.

Das Tampondruckverfahren kann kontinuierlich durchgeführt werden und kann jede bekannte Form des Tampondruckverfahrens sein, beispielsweise ein Rotationstampondruckverfahren.The pad printing process can be carried out continuously and can be any known form of the pad printing process, for example a rotary pad printing process.

Der Beutel besteht aus einer wasserlöslichen oder wasserdispergierbaren Umhüllung, welche eine geschlossene Struktur ausbildet, die in Ihrem Inneren eine oder mehrere Kammern zur Aufnahme eines oder mehrerer Mittel aufweist. Die wasserlösliche oder wasserdispergierbare Umhüllung wird durch ein wasserlösliches oder wasserdisperglerbares Folienmaterial gebildet.The bag consists of a water-soluble or water-dispersible envelope, which forms a closed structure which has one or more chambers inside for receiving one or more agents. The water-soluble or water-dispersible covering is formed by a water-soluble or water-dispersible film material.

Der Beutel kann jede Form haben, wobei die Form den Gebrauchsgegebenheiten weitgehend angepasst ist, ist aber üblicherweise schlauch-, kissen-, zylinder-, flaschen- oder scheibenförmig. Der Folienbeutel kann, in verschiedenen Ausführungsformen, eine Lange von 20 bis 50 mm, eine Breite von 15 bis 50 mm und eine Höhe von 10 bis 50 mm aufweisen. Die Beutel bestehen üblicherweise aus zwei aufeinander gelegten, am Rand miteinander verklebten/verschweißten Folienstücken und weisen daher eine mit dem Mittel gefüllte von Folie umhüllte Kavität und einen umlaufenden Rand auf. Ist die Grundform der Folienstücke rechteckig kann so eine Kissenform, ist die Grundform rund eine Scheibenform entstehen. Alternativ kann der Folienbeutel auch aus einer einzigen Folienbahn die gerollt und mit sich selbst verklebt/verschweißt wird bestehen, wodurch auch Schlauch- und Zylinderformen entstehen können.The bag can have any shape, the shape being largely adapted to the conditions of use, but is usually tubular, pillow, cylindrical, bottle or disc-shaped. In various embodiments, the film bag can have a length of 20 to 50 mm, a width of 15 to 50 mm and a height of 10 to 50 mm. The bags usually consist of two pieces of film placed one on top of the other, glued / welded to one another at the edge, and therefore have a cavity which is filled with the agent and are surrounded by film and a peripheral edge. If the basic shape of the film pieces is rectangular, a pillow shape can be created, and the basic shape can be around a disc shape. Alternatively, the film bag can also consist of a single film web that is rolled and glued / welded to itself, which can also result in tube and cylinder shapes.

In verschiedenen Ausführungsformen weist der Beutel zwei gegenüberliegende annähernd konvexe Oberflächen auf, die bedruckt werden können. Es ist bevorzugt, dass der Folienbeutel im Druckbereich keine Falten aufweist. Das kann beispielsweise dadurch erreicht werden, dass der Beutel nach der Herstellung einen höheren Innendruck als Außendruck aufweist. In verschiedenen Ausführungsformen der Erfindung wird eine, in anderen Ausführungsformen auch beide Oberflächen bedruckt. Das Motiv kann dabei gleich oder unterschiedlich sein.In various embodiments, the pouch has two opposite, approximately convex surfaces that can be printed on. It is preferred that the film bag has no folds in the printing area. This can be achieved, for example, in that the bag has a higher internal pressure than external pressure after manufacture. In various embodiments of the invention, one surface, in other embodiments also both surfaces, is printed. The motif can be the same or different.

Generell ist das aufgedruckte Druckbild in keiner Weise eingeschränkt, es handelt sich aber üblicherweise um Buchstaben, Zahlen, Symbolen, Ornamenten oder ähnliches, insbesondere Schriftzüge und/oder graphische Muster. Konkrete Beispiele sind Marken- oder Produktnamen sowie Herstellerlogos, Benutzungsanweisungen, Sicherheitshinweise, o.ä.. Das Motiv kann ein- oder mehrfarbig sein, wobei bei mehrfarbigen Motiven in mehreren Schritten verschiedene Farbtinten aufgedruckt werden können (z.B. Vierfarbdruck). Die Größe und Platzierung des Druckbilds ist vorzugsweise so gewählt, dass auf jeden Folienbeutel ein vollständiges Druckbild aufgedruckt werden kann.In general, the printed image is not restricted in any way, but it is usually letters, numbers, symbols, ornaments or the like, in particular lettering and / or graphic patterns. Specific examples are brand or product names as well as manufacturer logos, instructions for use, safety instructions, etc. The motif can be single or multi-colored, with multi-colored motifs different color inks can be printed in several steps (eg four-color printing). The size and placement of the printed image is preferably selected so that a complete printed image can be printed on each foil bag.

Die für die Herstellung des Folienbeutels verwendete Folie kann einen vordefinierten Bereich aufweisen, auf welchen mittels des erfindungsgemäßen Verfahrens der Aufdruck aufgedruckt wird. Dieser vordefinierte Bereich kann in verschiedenen Ausführungsformen gefärbt, bzw. anders gefärbt als der Rest der Folie sein. Vorstellbar ist beispielsweise ein weißbedruckter Bereich. Der Bereich kann ebenfalls mit einer Schicht bedeckt bzw. bedruckt sein, die die aufgedruckte Tinte von der darunter liegenden wasserlöslichen Folie trennt. Bei dieser Schicht kann es sich beispielsweise um eine wie unten beschriebene Schutzschicht handeln.The film used for the production of the film bag can have a predefined area on which the imprint is printed by means of the method according to the invention. In various embodiments, this predefined area can be colored or colored differently from the rest of the film. For example, a white-printed area is conceivable. The area can also be covered or printed with a layer that separates the printed ink from the underlying water-soluble film. This layer can, for example, be a protective layer as described below.

Die Ausdrücke "wasserlöslich" und "wasserdispergierbar", wie sie hierin verwendet werden, beziehen sich auf die Eigenschaft der Folie sich bei Kontakt mit Wasser aufzulösen bzw. zu zerfallen und den Inhalt des Folienbeutels freizugeben. Es ist bevorzugt, dass sich die Bestandteile der Folie möglichst rückstandsfrei in Wasser auflösen oder dispergieren lassen. In verschiedenen Ausführungsformen bedeutet "wasserlöslich", dass sich die entsprechende Folie in Wasser mit einer Temperatur von 20°C oder weniger innerhalb von 90 Sekunden auflöst. Entsprechende Testverfahren sind beispielsweise in US 6,787,512 B1 beschrieben.The terms "water-soluble" and "water-dispersible" as used herein refer to the property of the film to dissolve or disintegrate on contact with water and to release the contents of the film bag. It is preferred that the components of the film can be dissolved or dispersed in water with as little residue as possible. In various embodiments, “water-soluble” means that the corresponding film dissolves in water at a temperature of 20 ° C. or less within 90 seconds. Corresponding test procedures are for example in US 6,787,512 B1 described.

Der Beutel kann aus einer oder aus zwei oder mehr Lagen aus dem wasserlöslichen oder wasserdispergierbaren Folienmaterial gebildet werden. Das wasserlösliche oder wasserdispergierbare 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.Suitable water-soluble or water-dispersible films for producing the film bag are preferably based on a polymer or polymer mixture, in particular polyvinyl alcohol or a polyvinyl alcohol copolymer.

Ähnliches gilt für Polyvinylalkoholcopolymere, die aus entsprechend aus Polyvinylacetatcopolymeren hergestellt werden. Bevorzugt ist, wenn wenigstens eine Lage der wasserlöslichen oder wasserdispergierbaren 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.Polyvinyl alcohol is usually produced by hydrolysis of polyvinyl acetate, since the direct route of synthesis is not possible. The same applies to polyvinyl alcohol copolymers which are produced from polyvinyl acetate copolymers accordingly. It is preferred if at least one layer of the water-soluble or water-dispersible coating comprises a polyvinyl alcohol, the degree of hydrolysis of which is 70 to 100 mol%, preferably 80 to 90 mol%, particularly preferably 81 to 89 mol% and in particular 82 to 88 mol% .

Other suitable films include films with the designation Solublon® PT, Solublon® GA, Solublon® KC or Solublon® KL from Aicello Chemical Europe GmbH or the films VF-HP from Kuraray.

Die Herstellung der Folienbeutel erfolgt üblicherweise durch Tiefziehen (Thermoformen), d.h. das Erwärmen und Umformen von thermoplastischen Kunststoffen, im vorliegenden Fall der wasserlöslichen oder wasserdispergierbaren Folie. In diesen Verfahren wird die Folie erwärmt und in die gewünschte Form gebracht. Diese Formgebungsverfahren schließen einen Schritt zum Befüllen des vorgeformten Folienbeutels sowie einen weiteren Schritt, um den gefüllten Folienbeutel anschließend zu verschließen, ein.The film bags are usually produced by deep drawing (thermoforming), i.e. the heating and forming of thermoplastic materials, in this case the water-soluble or water-dispersible film. In this process, the film is heated and brought into the desired shape. These shaping processes include a step for filling the preformed film bag and a further step for subsequently closing the filled film bag.

Im Allgemeinen existieren mehrere Möglichkeiten zur Herstellung der wasserlöslichen oder wasserdispergierbaren Folienbeutel. Neben dem vertikalen Form-Füll-Siegel-Verfahren bietet sich insbesondere auch der Einsatz eines horizontalen Form-Füll-Siegel-Verfahrens an.In general, there are several options for producing the water-soluble or water-dispersible film bags. In addition to the vertical form-fill-seal process, the use of a horizontal form-fill-seal process is also particularly suitable.

Die Herstellung eines wasserlöslichen oder wasserdispergierbaren Folienbeutels kann die folgenden Schritte umfassen:

  1. a) Ausbilden wenigstens einer Kavität in einer ersten wasserlöslichen oder wasserdispergierbaren Folienbahn,
  2. b) Befüllen der wenigstens einen Kavität mit einem Mittel und
  3. c) Verschließen der Kavität mit einer zweiten wasserlöslichen oder wasserdispergierbaren Folienbahn.
The production of a water-soluble or water-dispersible film bag can include the following steps:
  1. a) forming at least one cavity in a first water-soluble or water-dispersible film web,
  2. b) filling the at least one cavity with an agent and
  3. c) closing the cavity with a second water-soluble or water-dispersible film web.

Dieses Verfahren kann dem erfindungsgemäßen Druckverfahren vorgeschaltet sein, so dass in einer Ausführungsform des erfindungsgemäßen Druckverfahrens die Schritte zur Herstellung einer wasserlöslichen oder wasserdispergierbaren Verpackung eingeschlossen sind. In einem solchen Verfahren schließt sich an Schritt c) ein weiterer Verfahrenschritt d) an, der die zumindest teilweise Bedruckung der äußeren Oberfläche der wasserlöslichen oder wasserdispergierbaren Umhüllung mit einer Tinte oder einem anderen Medium, das eine farbgebende Substanz enthält, umfasst. Der Schritt d) kann beliebig oft wiederholt werden, so dass mehrere gleich oder unterschiedliche bedruckte Bereiche auf der äußeren Oberfläche der wasserlöslichen oder wasserdispergierbaren Umhüllung entstehen. Schritt d) kann dabei das Tampondruckverfahren der Erfindung sein.This method can precede the printing method according to the invention, so that the steps for producing a water-soluble or water-dispersible packaging are included in one embodiment of the printing method according to the invention. In such a method, step c) is followed by a further method step d), which is the at least partial printing on the outer surface of the water-soluble or water-dispersible coating with an ink or other medium containing a coloring substance. Step d) can be repeated any number of times, so that several identical or different printed areas are formed on the outer surface of the water-soluble or water-dispersible coating. Step d) can be the pad printing process of the invention.

In verschiedenen Ausführungsformen des Verfahrens können mehrere Folienbeutel gleichzeitig bedruckt werden. Dazu können die Folienbeutel beispielsweise derart hergestellt werden, dass zwei oder mehr Folienbeutel nach dem Befüllen und Verschließen noch miteinander verbunden sind und diese gleichzeitig bedruckt und erst nach dem Bedrucken optional voneinander getrennt werden. In einem solchen Verfahren zur Herstellung und Bedrucken von Folienbeuteln, werden in der ersten Folienbahn mehrere Kavitäten ausgebildet und mit einem mittel befüllt und dann die entsprechenden Kavitäten mit einer zweiten Folienbahn verschlossen. Dazu können die beiden Folienbahnen um die jeweiligen Kavitäten herum verschweißt werden, so dass mehrere Beutel über die verschweißten Ränder miteinander verbunden sind. Diese können dann, falls gewünscht, in einem weiteren Schritt beispielsweise durch Schneiden zerstückelt werden so dass einzelne Folienbeutel, bzw. eine definierte Anzahl miteinander verbundener Folienbeutel erhalten wird.In various embodiments of the method, several foil bags can be printed on simultaneously. For this purpose, the film bags can be produced, for example, in such a way that two or more film bags are still connected to one another after filling and closing, and these are printed at the same time and optionally separated from one another only after printing. In such a process for the production and printing of film bags, a plurality of cavities are formed in the first film web and filled with a medium, and the corresponding cavities are then closed with a second film web. For this purpose, the two film webs can be welded around the respective cavities, so that several bags are connected to one another via the welded edges. If desired, these can then be dismembered in a further step, for example by cutting, so that individual film bags or a defined number of film bags connected to one another are obtained.

Das Bedrucken einer größeren Anzahl von miteinander verbundenen Folienbeuteln hat den Vorteil, dass die Platzierung, auch Register bei Mehrfarbdruck, vereinfacht wird.The printing of a large number of interconnected foil bags has the advantage that the placement, also register in multi-color printing, is simplified.

Ein weiterer Gegenstand der Erfindung ist demnach ein Verfahren zur Herstellung eines mit einem Wasch- oder Reinigungsmittel gefüllten Beutels aus einer wasserlöslichen oder wasserdispergierbaren Folie mit einem Aufdruck, umfassend die die Schritte:

  1. a) Ausbilden wenigstens einer Kavität in einer ersten wasserlöslichen oder wasserdispergierbaren Folienbahn,
  2. b) Befüllen der wenigstens einen Kavität mit einem Produkt,
  3. c) Verschließen der Kavität mit einer zweiten wasserlöslichen oder wasserdispergierbaren Folienbahn und
  4. d) zumindest teilweise Bedrucken der äußeren Oberfläche der wasserlöslichen oder wasserdispergierbare Folie mit einer Tinte oder einem Medium, die/das die farbgebende Substanz enthält, mittels eines Tampondruckverfahrens.
Another object of the invention is accordingly a method for producing a bag filled with a detergent or cleaning agent from a water-soluble or water-dispersible film with an imprint, comprising the steps:
  1. a) forming at least one cavity in a first water-soluble or water-dispersible film web,
  2. b) filling the at least one cavity with a product,
  3. c) closing the cavity with a second water-soluble or water-dispersible film web and
  4. d) at least partially printing on the outer surface of the water-soluble or water-dispersible film with an ink or a medium which contains the coloring substance, by means of a pad printing process.

In verschiedenen Ausführungsformen wird der Druckschritt d) dabei wie oben im Zusammenhang mit dem erfindungsgemäßen Druckverfahren beschrieben durchgeführt. Insbesondere lassen sich alle in diesem Zusammenhang hierin als bevorzugt offenbarten Ausführungsformen des Druckverfahrens auch auf den Druckschritt des Herstellungsverfahrens übertragen. Das Bedrucken der Folienoberfläche erfolgt vorzugsweise in dem Bereich der Folie, der die Kavität bedeckt oder umhüllt.In various embodiments, printing step d) is carried out as described above in connection with the printing method according to the invention. In particular, all of the embodiments of the printing process disclosed as preferred in this context can also be transferred to the printing step of the production process. The film surface is preferably printed in the area of the film that covers or envelops the cavity.

"Wenigstens eine", wie hierin verwendet, bezieht sich auf 1 oder mehr, vorzugsweise mindestens 2, 3, 4, 5, 10, 15, 20 oder mehr."At least one" as used herein refers to 1 or more, preferably at least 2, 3, 4, 5, 10, 15, 20 or more.

Wie bereits oben beschrieben können in verschiedenen Ausführungsformen des Verfahrens mehrere Kavitäten in einer ersten Folienbahn ausgebildet und befüllt und mit einer zweiten Folienbahn verschlossen werden, wobei dann das Bedrucken vor einem Ausschneiden der Folienbeutels aus einer mehrere verschlossene Kavitäten enthaltenden doppelten, vorzugsweise teilweise verschweißten Folienbahn stattfindet.As already described above, in various embodiments of the method, a plurality of cavities can be formed and filled in a first film web and closed with a second film web, the printing then taking place before the film bag is cut out of a double, preferably partially welded film web containing several closed cavities.

In einer Ausführungsform des Verfahrens werden daher mindestens zwei Kavitäten ausgebildet, befüllt und verschlossen und in Schritt d) Bereiche der jeweiligen Oberflächen der Folie, die die Kavitäten bildet, insbesondere der konvexen Oberflächen der Kavitäten, gleichzeitig bedruckt. Nach dem Druckschritt kann sich optional ein Schritt des Ausbildens der einzelnen oder mehreren miteinander verbundenen Folienbeutel anschließen, beispielsweise ein Schritt zum Ausschneiden der Folienbeutel aus der verklebten/verschweißten Folienbahn.In one embodiment of the method, therefore, at least two cavities are formed, filled and closed, and areas of the respective surfaces of the film which form the cavities, in particular the convex surfaces of the cavities, are simultaneously printed in step d). After the printing step, there can optionally be a step for forming the individual or several film bags connected to one another, for example a step for cutting out the film bags from the glued / welded film web.

Die eingesetzten Folien(bahnen) können frei von farbgebenden Substanzen sein, aber auch eine oder mehr farbgebende Substanzen enthalten. Die Bedruckung mit der farbgebenden Substanz kann dabei auf eingefärbten und/oder nicht eingefärbten Bereichen der mit einer farbgebenden Substanz zumindest teilweise eingefärbten Umhüllung erfolgen.The films (webs) used can be free of coloring substances, but can also contain one or more coloring substances. The printing with the coloring substance can take place on colored and / or non-colored areas of the covering, which is at least partially colored with a coloring substance.

In allen Ausführungsformen des Verfahrens zur Herstellung eines wasserlöslichen oder wasserdispergierbaren Folienbeutels erfolgt die Bedruckung der ersten wasserlöslichen oder wasserdispergierbaren Folie mit der farbgebenden Substanz nach dem Ausbilden und dem Verschließen der mit dem Mittel befüllten Kavität.In all embodiments of the method for producing a water-soluble or water-dispersible film bag, the printing of the first water-soluble or water-dispersible film with the coloring substance takes place after the formation and the sealing of the cavity filled with the agent.

Ein Vorteil der Bedruckung nach der Herstellung der Folienbeutel ist, dass die Bedruckung individualisiert, dass heißt entsprechend den Erfordernissen/Gegebenheiten, beispielsweise in Hinblick auf Form und Inhalt, der jeweilig, aktuell hergestellten wasserlöslichen oder wasserdispergierbaren Verpackung erfolgen kann. Beim Einsatz vorab bedruckter Folien, muss einerseits bei Änderungen der Zusammensetzung der wasserlöslichen oder wasserdispergierbaren Verpackung die Folienbahn ausgetauscht werden und das Herstellverfahren unterbrochen werden und andererseits mittels einer Streubedruckung der vorab bedruckten Folienbahn gewährleistet werden, dass die wasserlösliche oder wasserdispergierbare Umhüllung zumindest teilweise eingefärbt ist. Eine gezielte Positionierung der Einfärbung ist dabei anders als bei der vorliegenden Erfindung nicht möglich.An advantage of the printing after the production of the film bags is that the printing can be individualized, that is, according to the requirements / circumstances, for example with regard to shape and content, of the respective, currently produced water-soluble or water-dispersible packaging. When using pre-printed films, the film web must be replaced on the one hand when the composition of the water-soluble or water-dispersible packaging changes, and the manufacturing process must be interrupted, and on the other hand it must be ensured that the water-soluble or water-dispersible wrapping is at least partially colored by means of scatter printing on the pre-printed film web. In contrast to the present invention, a targeted positioning of the coloring is not possible.

Dem Druckvorgang kann sich optional ein Trocknungsverfahren anschließen, bei dem durch Auf- oder Überblasen von temperiertem Gas, Durchlaufen eines Trocknungsofens oder Bestrahlung mit Infrarotlicht das in der Tinte oder in dem Medium, die/das die farbgebende Substanz enthält, enthaltene Lösungsmittel verdampft/entfernt wird. Alternativ kann sich dem Druckvorgang ein Härtungsverfahren mit UV-Licht anschließen.The printing process can optionally be followed by a drying process in which the solvent contained in the ink or in the medium which contains the coloring substance is evaporated / removed by blowing up or blowing over tempered gas, passing through a drying oven or irradiation with infrared light . Alternatively, a curing process with UV light can follow the printing process.

Zusätzlich kann es bei einer Bedruckung der äußeren Oberfläche der wasserlöslichen oder wasserdispergierbaren Folien-Umhüllung von Vorteil sein, dass ein wasserlöslicher oder wasserdispergierbarer Schutzlack auf die bedruckten Bereiche der wasserlöslichen oder wasserdispergierbaren Umhüllung aufgebracht wird, um ein Verwischen und/oder Verschwinden der Einfärbung durch Luftfeuchtigkeit und/oder mechanische Belastung wie Reibung zu verhindern. Dieser wird vorzugsweise ebenfalls mittels eines Tampondruckverfahrens aufgedruckt. Diese Schutzlackschicht ist vorzugsweise klar durchsichtig und enthält keine Farbpartikel. Entsprechend geeignete Materialien sind im Stand der Technik bekannt.In addition, when printing on the outer surface of the water-soluble or water-dispersible film covering, it can be advantageous that a water-soluble or water-dispersible protective lacquer is applied to the printed areas of the water-soluble or water-dispersible covering in order to blur and / or disappear the coloring due to atmospheric moisture and / or to prevent mechanical stress such as friction. This is preferably also printed on using a pad printing process. This protective lacquer layer is preferably clear and contains no color particles. Appropriate materials are known in the prior art.

Das in den Folienbeuteln enthaltene Wasch- oder Reinigungsmittel kann fest, insbesondere pulverförmig, oder flüssig sein, ist aber vorzugsweise flüssig. Dabei schließt der Begriff "flüssig" auch gelförmige oder pastöse Mittel, mit oder ohne Fließgrenze, ein. Bei den Reinigungsmitteln handelt es sich vorzugsweise um maschinelle Geschirrspülmittel. Generell können alle geeigneten Wasch- oder Reinigungsmittel in den Folienbeuteln enthalten sein, vorzugsweise sind die Wasch- oder Reinigungsmittel aber wasserarm bis wasserfrei, um eine vorzeitige Auflösung der Folienumhüllung zu vermeiden.The washing or cleaning agent contained in the film bags can be solid, in particular powdery, or liquid, but is preferably liquid. The term "liquid" also includes gel-like or pasty agents, with or without a flow limit. The cleaning agents are preferably automatic dishwashing agents. In general, all suitable detergents or cleaning agents can be contained in the film bags, but the detergents or cleaning agents are preferably low-water to water-free in order to avoid premature dissolution of the film covering.

In einer Ausführungsform weist der Folienbeutel eine Kammer zur Aufnahme des Mittels auf. Das Mittel kann in dieser Ausführungsform vorzugsweise ein Pulver, ein Granulat, ein Gel oder eine Flüssigkeit umfassen. In einer weiteren Ausführungsform weist der Folienbeutel zwei Kammern auf. 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. Weist der Folienbeutel 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.In one embodiment, the film bag has a chamber for receiving the agent. In this embodiment, the agent can preferably comprise a powder, a granulate, a gel or a liquid. In a further embodiment, the film bag 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 can contain a solid agent. If the film bag has three compartments, they can each contain a liquid or a solid agent. However, it is also possible for one chamber to contain a solid agent and two chambers to contain a liquid agent. It is also possible that a solid agent is contained in two chambers and a liquid agent is contained in one chamber.

Bei wasserlöslichen oder wasserdispergierbaren 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 or water-dispersible packaging with four or more chambers, there are correspondingly more possible combinations in terms of the number of chambers with a solid or a liquid medium.

Die Mittel, die in den unterschiedlichen Kammern eines wasserlöslichen oder wasserdispergierbaren Folienbeutels enthalten sind, können dieselbe Zusammensetzung aufweisen. Vorzugsweise weisen die Mittel in einem wasserlöslichen oder wasserdispergierbaren Folienbeutel mit mindestens zwei Kammern Zusammensetzungen auf, die sich mindestens in einem Inhaltsstoff oder sich mindestens im Gehalt eines Inhaltsstoffes unterscheiden.The compositions contained in the different chambers of a water-soluble or water-dispersible film bag can have the same composition. In a water-soluble or water-dispersible film bag with at least two chambers, the agents preferably have compositions which differ in at least one ingredient or at least in the content of one ingredient.

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, Hautpflegende 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 or water-dispersible coating. If the agent used is a liquid or solid washing or cleaning agent, it can contain one or more substances from the group of surfactants, builders, bleaching agents, bleach activators, bleaching catalysts, enzymes, enzyme stabilizers, electrolytes, pH regulators, perfumes, perfume carriers, fluorescent agents, dyes, hydrotropes, foam inhibitors, silicone oils, antiredeposition agents, graying inhibitors, shrink preventatives, anticrease agents, dye transfer inhibitors, antimicrobial agents, non-aqueous solvent, germicides, fungicides, antioxidants, preservatives, corrosion inhibitors, antistatic agents, bitter agents, ironing aids, waterproofing and impregnating agents, opacifying agents, skin benefit agents, Contain swelling and anti-slip agents, plasticizing components, fillers and UV absorbers.

Wie bereits oben erwähnt können die flüssigen Wasch- oder Reinigungsmittel wasserarm oder wasserfrei sein.As already mentioned above, the liquid washing or cleaning agents can be low in water or water-free.

Der Ausdruck "wasserarm", wie hierin verwendet, bedeutet, dass die derart charakterisierte Zusammensetzung weniger als 25 Gew.-% Wasser, vorzugsweise weniger als 20 Gew.-% Wasser enthält. Insbesondere fallen unter diesen Begriff Zusammensetzungen, die 1 bis 20 Gew.-% Wasser, 1 bis 15 Gew.-% Wasser, 5-15 Gew.-% Wasser oder 10 bis weniger als 20 Gew.-% Wasser enthalten.The term "low water" as used herein means that the composition so characterized contains less than 25% by weight of water, preferably less than 20% by weight of water. In particular, this term includes compositions which contain 1 to 20% by weight of water, 1 to 15% by weight of water, 5-15% by weight of water or 10 to less than 20% by weight of water.

"Wasserfrei", wie hierin verwendet, bedeutet, dass eine Zusammensetzung weniger als 5 Gew.-%, insbesondere weniger als 3 Gew.-%, vorzugsweise kleiner 1 Gew.-% Wasser enthält."Anhydrous" as used herein means that a composition contains less than 5% by weight, especially less than 3% by weight, preferably less than 1% by weight of water.

Der Wassergehalt wie hierin definiert bezieht sich auf den mittels der Karl Fischer Titration ermittelten Wassergehalt.The water content as defined herein relates to the water content determined by means of the Karl Fischer titration.
