However, it is also possible to decorate the foil strip ornamentally, e.g. in flower form, flower shape, animal form or the like.

Der Folienstreifen ist bedruckt. In diesem Zusammenhang ist es insbesondere zu bevorzugen, dass die Bedruckung des Folienstreifens wasserlöslich ist.The foil strip is printed. In this context, it is particularly preferable that the printing of the film strip is water-soluble.

Die Bedruckung kann vorzugsweise Schrift und/oder Symbole und/oder Formen umfassen. Insbesondere kann die Bedruckung als Herkunftshinweis der wasserlöslichen Verpackung dienen, beispielsweise durch Aufdruck einer Marke und/oder Produktnamens. Ferner kann die Bedruckung als ein Benutzungs- und/oder Warnhinweis in Verbindung mit der wasserlöslichen Verpackung ausgebildet sein.The printing may preferably comprise writing and / or symbols and / or shapes. In particular, the printing can serve as an indication of the origin of the water-soluble packaging, for example by imprinting a brand and / or product name. Furthermore, the printing may be formed as a use and / or warning in connection with the water-soluble packaging.

Methoden zur Bedruckung des wasserlöslichen Folienstreifens sind aus dem Stand der Technik bekannt. Grundsätzlich kann jede Form des Bedruckens verwendet werden wie beispielsweise Rotogravure, Lithographie, Flexographie, Tintenstrahldruck, Tampographie oder beliebige Kombinationen dieser Drucktechnologie.Methods for printing on the water-soluble film strip are known from the prior art. In principle, any form of printing can be used such as rotogravure, lithography, flexography, inkjet printing, tampography or any combination of this printing technology.

Die Bedruckung des Folienstreifens erfolgt bevorzugt mit einer wasserlöslichen Tinte oder einem anderen, geeigneten wasserlöslichen Farbe.

Um einen zusätzlichen mechanischen Schutz insbesondere vor Abrieb bereitzustellen, kann die bedruckte Seite des Folienstreifens von einer wasserlöslichen Folie überdeckt sein, wobei diese Deckfolie insbesondere transparent ausgebildet ist, so dass das Druckbild des Folienstreifens sichtbar ist. Der Folienstreifen und die Deckschicht können stoffschlüssig miteinander verbunden sein, beispielsweise mittels Befestigungspunkten, durch eine umlaufende Verbindungskante oder einer teil- oder vollflächigen Verbindung. Die Verbindung kann mittels einer separaten Klebstoffs ausgebildet sein oder durch ein leichtes Anfeuchten wenigstens einer der wasserlöslichen Folien.In order to provide additional mechanical protection, in particular against abrasion, the printed side of the film strip can be covered by a water-soluble film, wherein this cover film is particularly transparent, so that the printed image of the film strip is visible. The film strip and the cover layer can be materially connected to each other, for example by means of attachment points, by a circumferential connecting edge or a partial or full surface connection. The compound may be formed by means of a separate adhesive or by slightly moistening at least one of the water-soluble films.

Alternativ zu einer aus einer wasserlöslichen Folie gebildeten Deckschicht eines bedruckten Folienstreifens kann der bedruckte Folienstreifen auch mit einem wasserlöslichen Lack versehen werden, der beispielsweise auf das Druckbild aufgesprüht wird. Der Lack ist hierbei bevorzugt transparent, damit das Druckbild des Folienstreifens sichtbar bleibt.As an alternative to a cover layer of a printed film strip formed from a water-soluble film, the printed film strip can also be provided with a water-soluble lacquer which is sprayed onto the printed image, for example. The paint is preferably transparent so that the printed image of the film strip remains visible.

Der Folienstreifen kann transparent, transluzent oder opak ausgebildet sein.The film strip may be transparent, translucent or opaque.

Der Folienstreifen überdeckt zwischen 10% und 90% der inneren oder äußeren Oberfläche der wasserlöslichen Verpackung, wodurch eine hinreichend große Kontaktfläche für den Stoffschluss zwischen den Oberflächen der wasserlöslichen Verpackung und des Folienstreifens bereitgestellt wird.The film strip covers between 10% and 90% of the inner or outer surface of the water-soluble package, thereby providing a sufficiently large interface for interfacial bonding between the surfaces of the water-soluble package and the film strip.

Es ist ferner möglich eine Mehrzahl von Folienstreifen auf und/oder in der wasserlöslichen Verpackung anzuordnen, wobei sich die Folienstreifen bevorzugt voneinander hinsichtlich ihrer Bedruckung und/oder enthaltenen Aktivstoffs unterscheiden.It is also possible to arrange a plurality of film strips on and / or in the water-soluble packaging, wherein the film strips preferably differ from each other with regard to their printing and / or active substance contained.

Der Folienstreifen kann auch fähnchenartig mit der wasserlöslichen Verpackung verbunden sein, wobei er mit 5-100% seiner Oberfläche mit der inneren oder äußeren Oberfläche der wasserlöslichen Verpackung stoffschlüssig verbunden ist. Hierbei ist nahe dem äußeren Rand des Folienstreifens ein Klebepunkt vorgesehen.The film strip may also be flagged to the water-soluble package, being bonded to 5-100% of its surface with the inner or outer surface of the water-soluble packaging. Here, a glue dot is provided near the outer edge of the film strip.

Um mit Hilfe des Folienstreifens eine Schlaufe an der wasserlöslichen Verpackung auszubilden ist es bevorzugt, dass der Folienstreifen mit zwei voneinander beabstandeten Klebepunkten derart auf der äußeren Oberfläche der wasserlöslichen Verpackung verbunden ist, dass der Folienstreifen eben eine solche Schlaufe bildet. Die Schlaufe kann insbesondere als Greifhilfsmittel für einen Benutzer dienen.In order to form a loop on the water-soluble packaging with the aid of the film strip, it is preferred for the film strip to be connected to two spaced adhesive dots on the outer surface of the water-soluble packaging in such a way that the film strip forms such a loop. The loop can serve in particular as a gripping aid for a user.

In diesem Zusammenhang ist es besonders vorteilhaft, dass die Klebepunkte mittels eines wasserlöslichen Klebstoffs, wie z.B. eines Acrylat-Haftklebestoffs, gebildet sind.In this connection, it is particularly advantageous that the adhesive dots are sealed by means of a water-soluble adhesive, such as e.g. an acrylate pressure-sensitive adhesive, are formed.

Aktivstoff in oder auf FolienstreifenActive substance in or on foil strips

In einer erfindungsgemäßen Weiterentwicklung der wasserlöslichen Verpackung ist der Folienstreifen Träger eines Aktivstoffes, insbesondere eines Duftstoffes oder einer Duftstoffzusammensetzung. Ein weiterer bevorzugter Aktivstoff ist ein Bläuungsmittel.In a further development of the water-soluble packaging according to the invention, the film strip is a carrier of an active substance, in particular a fragrance or a fragrance composition. Another preferred active is a blueing agent.

DuftstoffzusammensetzungPerfume composition

Duftstoffe werden Mitteln, insbesondere Wasch- oder Reinigungsmitteln, zugesetzt, um den ästhetischen Gesamteindruck der Produkte zu verbessern und dem Verbraucher neben der technischen Leistung (z.B. Reinigungsleistung) ein sensorisch typisches und unverwechselbares Produkt zur Verfügung zu stellen. Wasserlösliche Verpackungen besitzen jedoch üblicherweise die Eigenschaft, dass Duftstoffzusammensetzungen aus den in ihnen bevorrateten Mitteln schlecht oder gar nicht durch die wasserlösliche Umhüllung hindurch an die Umgebung abgegeben werden. Somit kann der Dufteindruck derartiger in wasserlöslichen Verpackungen bevorrateter Mittel von einem Benutzer nicht oder nur sehr unzureichend wahrgenommen werden. Von daher ist es vorteilhaft, dass in oder auf dem Folienstreifen als Aktivstoff ein Duftstoff oder eine Duftstoffzusammensetzung umfasst ist.Fragrances are added to detergents, in particular detergents, in order to improve the overall aesthetic appearance of the products and to provide the consumer, in addition to technical performance (e.g., cleaning performance), with a sensory typical and distinctive product. However, water-soluble packages usually have the property that fragrance compositions are poorly or not at all discharged from the stored in them through the water-soluble envelope to the environment. Thus, the scent impression of such funds stored in water-soluble packaging means by a user can not be perceived or only very insufficient. It is therefore advantageous that a fragrance or a fragrance composition is included in or on the film strip as active substance.

Als Duftstoffe können einzelne Verbindungen verwendet werden, beispielsweise die synthetischen Produkte vom Typ der Ester, Ether, Aldehyde, Ketone, Alkohole und Kohlenwasserstoffe.

Bläuungsmittelbluing agents

Seit langem ist es üblich, den Weißgrad von Textilien mit Hilfe von optischen Aufhellern oder Bläuungsmittel zu verbessern. Insbesondere soll mit diesen Verbindungen ein Gelbstich von weißen Textilien, der mit der Zeit auftritt, kompensiert werden. Beim Bläuen verwendet man blaue bzw. blauviolette Farbstoffe geringer Faseraffinität in sehr niedriger Konzentration, um eine egale, mit freiem Auge nicht sichtbare Anfärbung der Textilien zu erhalten. Der beim Bläuen erzielte verbesserte Weißeffekt beruht auf einer Senkung der gelben Anteile des ins Auge des Beobachters reflektierten Lichtes.It has long been common to improve the whiteness of fabrics with the aid of optical brighteners or bluing agents. In particular, should be compensated with these compounds a yellow cast of white textiles, which occurs over time. Blueing uses blue or blue-violet dyes of low fiber affinity in very low concentrations to obtain a level dyeing of textiles that is invisible to the naked eye. The enhanced whitening effect achieved by blueing is due to a reduction in the yellow portion of the light reflected in the observer's eye.

Um eine Anreicherung des Bläuungsmittels auf den Textilien zu verhindern, werden Bläuungsmittel nur in geringer Konzentration eingesetzt. Die Einsatzmenge an Bläuungsmittel kann mit Hilfe einer Dosierung über den Folienstreifen besser kontrolliert werden.To prevent accumulation of the bluing agent on the textiles, bluing agents are used only in low concentrations. The amount of bluing agent can be better controlled by means of a dosage over the film strip.

Geeignete Bläuungsmittel sind beispielsweise Farbstoffe, die in der Color Index (C.I.) Klassifikation als Direct Blue, Direct Red, Direct Violet, Acid Blue, Acid Red, Acid Violet, Basic Blue, Basic Violet oder Basic Red bezeichnet werden. Alternativ können auch polymere Farbstoffe wie sie beispielsweise von der Firma Milliken unter der Bezeichnung "Liquitint(R)" erhältlich sind. Auch Pigmente wie Ultramarin eignen sich als Bläuungsmittel.Suitable bleaches are, for example, dyes referred to in the Color Index (C.I.) classification as Direct Blue, Direct Red, Direct Violet, Acid Blue, Acid Red, Acid Violet, Basic Blue, Basic Violet or Basic Red. Alternatively, polymeric dyes such as those available from Milliken under the name "Liquitint®" are also available. Even pigments such as ultramarine are suitable as bluing agents.

Besonders bevorzugte Bläuungsmittel sind Basic Violet 10, Ultramarin, Liquitint(R) Blue HP oder Verbindungen der folgenden Formel:

In den nachfolgenden Abbildungen werden wasserlösliche Verpackungen mit zwei Kammern beschrieben. Selbstverständlich ist die Erfindung ebenso gut für wasserlösliche Verpackungen mit einer Kammer oder mehr als 2 Kammern geeignet und nicht auf die gezeigten Zweikammer-Ausführungen beschränkt.The following figures describe water-soluble packages with two chambers. Of course, the invention is equally well suited for water-soluble packaging with a chamber or more than 2 chambers and not limited to the two-chamber designs shown.

Fig. 1 zeigt ein erstes Ausführungsbeispiel einer erfindungsgemäßen, wasserlöslichen Verpackung 1. Die wasserlösliche Verpackung 1 weist eine erste Kammer 2 zur Aufnahme eines ersten Mittels und eine zweite Kammer 3 zur Aufnahme eines zweiten Mittels auf. Die wasserlösliche Verpackung 1 ist aus einer wasserlöslichen Folie gebildet, wobei die Folie durch eine umlaufende Siegelnaht verschlossen ist, wodurch die erste und zweite Kammer ausgebildet wird. Auf der äußeren Oberfläche der zweiten Kammer 3 der wasserlöslichen Verpackung 1 ist ein ovaler Folienstreifen 4 vollflächig stoffschlüssig angeordnet. Der Folienstreifen 4 weist eine Bedruckung auf, was durch die Schraffur des Folienstreifens 4 symbolisiert ist. Fig. 1 shows a first embodiment of a water-soluble packaging according to the invention 1. The water-soluble packaging 1 has a first chamber 2 for receiving a first means and a second chamber 3 for receiving a second agent. The water-soluble packaging 1 is formed from a water-soluble film, wherein the film is closed by a circumferential sealing seam, whereby the first and second chamber is formed. On the outer surface of the second chamber 3 of the water-soluble packaging 1, an oval film strip 4 is arranged over the entire surface with a material fit. The film strip 4 has a printing, which is symbolized by the hatching of the film strip 4.

Selbstverständlich ist es auch möglich, dass jede der beiden Kammern 2,3 der aus Fig. 1 bekannten Verpackung 1 einen Folienstreifen 4 trägt, was in Fig. 2 gezeigt ist. In diesem Ausführungsbeispiel unterscheidet sich die Bedruckung des ersten Folienstreifens 4a von dem des zweiten Folienstreifens 4b, was wiederum durch die unterschiedlichen Schraffuren kenntlich gemacht wurde.Of course, it is also possible that each of the two chambers 2.3 of Fig. 1 known packaging 1 carries a film strip 4, which is in Fig. 2 is shown. In this embodiment, the printing of the first film strip 4a differs from that of the second film strip 4b, which in turn was indicated by the different hatching.

Neben der vollflächigen, stoffschlüssigen Verbindung eines Folienstreifens 4 mit der wasserlöslichen Verpackung 1 ist es auch möglich, dass der Folienstreifen lediglich mit einem Teil seiner Oberfläche stoffschlüssig mit der wasserlöslichen Verpackung verbunden ist. Dies wird anhand einiger Ausführungsbeispiele gemäß den Fig. 3-7 näher erläutert.In addition to the full-surface, cohesive connection of a film strip 4 with the water-soluble packaging 1, it is also possible that the film strip is only materially connected to a part of its surface with the water-soluble packaging. This will be explained with reference to some embodiments according to the Fig. 3-7 explained in more detail.

Fig. 3 zeigt die aus den Fig. 1-2 bekannte Zweikammerverpackung. Auf der äußeren Oberfläche der zweiten Kammer 3 der Verpackung 1 ist ein Folienstreifen 4 lediglich über die Verbindungsfläche 5 stoffschlüssig mit der Kammer 3 verbunden, während die übrigen Flächen des Folienstreifens 4 keine Verbindung zu der wasserlöslichen Verpackung 1 aufweisen. Somit ist der Folienstreifen 4 fähnchenartig mit der wasserlöslichen Verpackung 1 verbunden. Durch diese Art der Ausgestaltung ist es beispielsweise möglich, dass der derart fähnchenartig ausgebildete Folienstreifen 4 auch als Griffelement für einen Benutzer dienen kann. Dies ist insoweit von Bedeutung, da die wasserlöslichen Verpackungen 1 empfindlich gegenüber Feuchtigkeit sind, also auch hinsichtlich nasser oder feuchter Finger eines Benutzers. Wird eine wasserlösliche Verpackung 1 mit nassen Fingern gegriffen, so kann es zu einem ungewollten Auflösen und Auslaufen der wasserlöslichen Verpackung kommen. Dieses Risiko wird minimiert, wenn der Benutzer die Verpackung an dem fähnchenartig angeordneten Folienstreifen 4 greifen kann, so dass kein unmittelbarer Kontakt zwischen den Findern des Benutzers und den Kammern 2,3 der Verpackung 1 entsteht. Zwar könnte es auch auch zu einem Anlösen des Folienstreifens 4 kommen, doch hätte dies lediglich ästhetische Nachteile und kein - in der Wahrnehmung eines Benutzers - Versagen der Verpackung 1 zur Folge. Fig. 3 shows those from the Fig. 1-2 known two-chamber packaging. On the outer surface of the second chamber 3 of the package 1, a film strip 4 is only materially connected to the chamber 3 via the connecting surface 5, while the remaining surfaces of the film strip 4 have no connection to the water-soluble packaging 1. Thus, the film strip 4 is fähnchen connected to the water-soluble packaging 1. This type of embodiment makes it possible, for example, for the film strip 4, which is formed like a flag, to also serve as a grip element for a user. This is of importance insofar as the water-soluble packages 1 are sensitive to moisture, thus also with respect to wet or wet fingers of a user. If a water-soluble packaging 1 is gripped with wet fingers, it may lead to an unwanted dissolution and leakage of the water-soluble packaging. This risk is minimized if the user can grip the packaging on the flag-like foil strip 4, so that no direct contact between the user's finder and the chambers 2, 3 of the packaging 1 arises. Although it could also come to a dissolution of the film strip 4, but this would only aesthetic disadvantages and no - in the perception of a user - failure of the package 1 result.

Es ist natürlich möglich, ein fähnchenartig auf bzw. an der Verpackung 1 angeordnetes Streifenelement 4, wie es auf Fig. 3 bekannt ist, an jeder geeigneten Stelle der Verpackung zu platzieren. So kann zwischen dem Streifenelement 4 und der Verpackung 1 beispielsweise auch auf einem Abschnitt der Siegelnaht der wasserlöslichen Verpackung 1 eine Verbindungsfläche 5 ausgebildet sein, was in Fig. 4 gezeigt ist. Die Verbindungsfläche 5 kann sich, wie in Fig. 5 gezeigt, auch über eine gesamte Kantenlänge einer Siegelnaht erstrecken. Durch die gegenüber in den vorangestellten Ausführungsbeispielen vergrößerte Kontaktfläche kann eine besonders feste formschlüssige Verbindung zwischen dem Folienstreifen 4 und der wasserlöslichen Verpackung 4 erzielt werden.It is of course possible, a flag-like on or on the package 1 arranged strip element 4, as it is on Fig. 3 is known to place at any suitable location of the packaging. Thus, between the strip element 4 and the packaging 1, for example, also on a portion of the sealed seam of the water-soluble packaging 1, a connecting surface 5 may be formed, which is shown in FIG Fig. 4 is shown. The connection surface 5 may, as in Fig. 5 also extend over an entire edge length of a sealed seam. As a result of the contact surface that is enlarged in the preceding embodiments, a particularly strong positive connection between the film strip 4 and the water-soluble packaging 4 can be achieved.

Neben einer Verbindungsfläche 5, welche zwischen dem Folienstreifen 4 und der Verpackung 1 ausgebildet ist, ist es auch möglich, zwei voneinander beabstandete Verbindungsflächen 5 an der Verpackung vorzusehen, was nachfolgend anhand der Ausführungsbeispiele der Fig. 6-7 erläutert wird.In addition to a connecting surface 5, which is formed between the film strip 4 and the package 1, it is also possible to provide two spaced connecting surfaces 5 on the packaging, which will be described below with reference to the embodiments of Fig. 6-7 is explained.

In Fig. 6 ist der Folienstreifen 4 so durch seine distalen Enden mit einer Verbindungsfläche 5 am Kopf und am Boden (nicht sichtbar) der wasserlöslichen Verpackung 1 verbunden, dass sich eine Schlaufe ausbildet. Diese Schlaufe kann als Griffelement für einen Benutzer dienen, so dass er die wasserlösliche Verpackung 1 nicht unmittelbar mit seinen Fingern berühren muss. Neben der in Fig. 6 gezeigten Ausführungsform ist es alternativ auch möglich, die Schlaufe so auszubilden, dass die Verbindungsflächen 5a,5b des Folienstreifens 4 auf der Kopfseite der wasserlöslichen Verpackung 1 angeordnet sind.In Fig. 6 the foil strip 4 is thus connected by its distal ends to a connecting surface 5 at the head and at the bottom (not visible) of the water-soluble packaging 1, so that a loop is formed. This loop may serve as a grip member for a user, so that he does not have to touch the water-soluble package 1 directly with his fingers. In addition to the in Fig. 6 As shown, it is alternatively also possible to form the loop in such a way that the connecting surfaces 5a, 5b of the film strip 4 are arranged on the head side of the water-soluble packaging 1.

Fig. 8 zeigt einen Folienstreifen 4b mit Deckschicht 4a in Querschnittsansicht. Hierbei ist der Folienstreifen 4b, der mit der wasserlöslichen Verpackung 1 verbunden ist, bedruckt. Der bedruckte Folienstreifen 4b ist mit einer transparenten, wasserlöslichen Deckschicht 4a überdeckt, so dass der bedruckte Folienstreifen 4b vor mechanischen Einflüssen oder einer unmittelbaren Exposition mit Wasser oder Wasserdampf geschützt ist. Fig. 8 shows a film strip 4b with cover layer 4a in cross-sectional view. Here, the film strip 4b, which is connected to the water-soluble packaging 1, printed. The printed film strip 4b is covered with a transparent, water-soluble cover layer 4a, so that the printed film strip 4b is protected against mechanical influences or direct exposure to water or water vapor.
