Description

Die Erfindung betrifft ein zumindest zweischichtiges Etikett zum Aufreißen und Wiederverschließen von flexiblen Verpackungen mit vorgeschnittener Öffnung sowie dessen Verwendung. Derartige Verpackungen enthalten beispielsweise öl- oder emulsionsgetränkte Feuchttücher.The invention relates to an at least two-layer label for tearing and reclosing of flexible packaging with pre-cut opening and its use. Such packages contain, for example, oil or emulsion-impregnated wet wipes.

Technische Etiketten werden in vielen Bereichen für hochwertige Anwendungen eingesetzt, so als Typenschilder für Fahrzeuge, Maschinen, elektrische und elektronische Geräte, als Steueretiketten für Prozessabläufe, als Garantie- und Prüfplaketten sowie als Verschlussetiketten.Technical labels are used in many areas for high-quality applications, such as nameplates for vehicles, machinery, electrical and electronic equipment, as process control labels, as warranty and inspection labels and as closure labels.

Zum Öffnen und Verschließen von flexiblen Verpackungen wie Schlauchbeuteln mit vorgeschnittener Öffnung, in denen zum Beispiel Feuchttücher verwahrt werden, werden üblicherweise einlagige Etiketten verwendet.For opening and closing of flexible packages such as tubular bags with pre-cut opening, in which, for example, wet wipes are stored, usually single-layer labels are used.

In die Verpackungsfolie des Schlauchbeutels ist ein Deckel, der das spätere Öffnungsloch bildet, perforiert. Durch das Öffnungsloch können die Feuchttücher entnommen werden. Das Loch wird mit dem Etikett überklebt, und beim Erstöffnen wird die Perforation des Deckels aufgerissen, das heißt, das den Deckel bildende Stück Folie bleibt an der Unterseite des Etiketts haften.In the packaging film of the tubular bag, a lid, which forms the later opening hole, perforated. The wet wipes can be removed through the opening hole. The hole is pasted over with the label, and at the first opening, the perforation of the lid is torn, that is, the piece of film forming the lid adheres to the underside of the label.

Die Etiketten weisen zumeist eine Anfasslasche auf, die entweder kleberfrei ist oder deren Kleber neutralisiert wurde. Um zu verhindern, dass das Etikett beim Öffnen der Verpackung vollständig vom Beutel abgezogen wird, besitzen die meisten dieser Etiketten eine geschwungene Stanzung, die dazu führt, dass ein gewisser Widerstand entsteht, wenn man das Etikett bis dorthin geöffnet hat. Der Widerstand zeigt an, dass man nicht weiter ziehen soll. Eine andere Möglichkeit zu verhindern, dass das Etikett vollständig abgezogen wird, besteht in dem Einsatz von zwei unterschiedlichen Klebstoffen: Ablösbar in dem Bereich, in dem das Etikett von der Verpackungsfolie abgezogen werden soll (Öffnen der Verpackung), permanent am Scharnier, um die vollständige Ablösung zu verhindern.The labels usually have a grip tab which is either adhesive-free or whose adhesive has been neutralized. In order to prevent the label from being completely peeled off the bag when the package is opened, most of these labels have a sweeping punch that results in some resistance arises when you have opened the label up to there. The resistance indicates that you should not move on. Another way to prevent the label from being completely peeled off is to use two different adhesives: removable in the area where the label is to be peeled from the packaging film (opening the package), permanently on the hinge, to the fullest Prevent detachment.

Diese Etiketten für Feuchttücherverpackungen bestehen aus drei hintereinander angeordneten, unterschiedlichen Zonen: Zone 1 nichtklebend, Zone 2 ablösbar klebend, Zone 3 permanent klebend.These labels for wet wipe packaging consist of three different zones arranged one behind the other: Zone 1 non-sticky, Zone 2 removable, Adhesive zone 3 permanent.

In der EP 0 331 027 A1 wird ein wiederverschließbarer Spenderbehälter für ölgetränkte Feuchtetücher offenbart, der aus einem Behälter und einem Schlüsselteil besteht. Der Behälter ist mit einem einlagigen Etikett zu verschließen. Der Verschluss des Behälters mit Hilfe des Etiketts ist aber unbefriedigend. Zum einen ist diese Art des Verschlusses nicht so dicht, als dass das Eindringen von Schmutz oder Staub in den Behälter ausgeschlossen werden kann, auf der anderen Seite ist das Etikett schon rein optisch wenig ansehnlich, insbesondere wenn die Klebkraft auf dem Behälter nachlässt.In the EP 0 331 027 A1 discloses a resealable dispensing container for oil-soaked wet wipes, which consists of a container and a key part. The container should be sealed with a single-layer label. The closure of the container by means of the label is unsatisfactory. On the one hand, this type of closure is not so dense as to preclude the ingress of dirt or dust into the container, on the other hand, the label is already visually unappealing, especially if the adhesive strength on the container wears off.

In der WO 93/17933 A wird ebenfalls ein Behälter offenbart, der zur Aufnahme von feuchten Tüchern dient, die sich ihrerseits in einem luftdichten Beutel befinden. Der Beutel wird in dem Behälter aufbewahrt. Weiterhin ist der Beutel mit einem einlagigen Etikett reversibel verschlossen. Auch hier treten die geschilderten Nachteile zutage.In the WO 93/17933 A Also, there is disclosed a container for holding wet wipes, which are in turn in an airtight bag. The bag is stored in the container. Furthermore, the bag is reversibly closed with a single-layer label. Again, the disadvantages described come to light.

In der FR2 766 794A wird ein Etikett gemäß dem Oberbegriff der Ansprüche 1 und 2 offenbad.In the FR2 766 794A a label according to the preamble of claims 1 and 2 is disclosed.

Aufgabe der vorliegenden Erfindung ist es, ein Etikett zu schaffen, das leicht zu öffnen ist und dennoch sicher auf dem Untergrund, insbesondere der Verpackung verklebt und das insbesondere - nicht wie die bekannten Etiketten - weitgehend beständig gegen Öl ist, das aus Feuchttüchern austreten können, die sich innerhalb einer Verpackung befinden, die mit dem erfindungsgemäßen Etikett reversibel verschlossen ist.The object of the present invention is to provide a label which is easy to open and yet securely adhered to the substrate, in particular the packaging and which in particular - unlike the known labels - is largely resistant to oil that can escape from wet wipes, which are located within a package that is reversibly closed with the label according to the invention.

Gelöst wird diese Aufgabe durch ein Etikett, wie es im Hauptanspruch dargelegt ist. Gegenstand der Unteransprüche sind vorteilhafte Fortbildungen des Erfindungsgegenstandes. Des Weiteren betrifft die Erfindung Verwendungsvorschläge des erfindungsgemäßen Etiketts.This problem is solved by a label, as set out in the main claim. The subject of the dependent claims are advantageous developments of the subject invention. Furthermore, the invention relates to proposed uses of the label according to the invention.

Demgemäß betrifft die Erfindung ein zumindest zweischichtiges Etikett zum Aufreißen und Wiederverschließen von flexiblen Verpackungen, die eine vorgeschnittene, mit einem Deckel verschlossene Öffnung aufweisen.
Das Etikett besteht aus einem Grundetikett,

  • dessen Unterseite mit einer ersten Klebeschicht ausgerüstet ist, die gegebenenfalls bis zur Verklebung des Etiketts mit einem Trennpapier oder einer Trennfolie abgedeckt ist,
  • in dem ein Ausschnitt vorgesehen ist, dessen Verbindung mit dem übrigen Grundetikett geschwächt oder durchtrennt ist,
    und mit einem Decketikett,
  • dessen Unterseite mit einer zweiten Klebeschicht ausgerüstet ist, mittels der das Decketikett auf dem Grundetikett verklebt ist,
wobei die Klebkraft des Grundetiketts auf dem Grund, auf dem das Etikett verklebt ist, höher als die Klebkraft des Decketiketts auf dem Grundetikett ist sowie die Klebkraft zwischen Ausschnitt und Decketikett höher ist als die Kraft, die erforderlich ist, den Deckel in der Verpackung mittels des darauf verklebten Ausschnitts aus der Verpackung zu trennen.
Gleichzeitig ist diese Klebkraft damit höher als die Kraft, die zum Trennen des Ausschnitts vom Grund, auf den das Etikett geklebt ist, erforderlich ist.
Gegebenenfalls sind auf dem Decketikett weitere Schutzetiketten vorgesehen, die beispielsweise in Leporellofaltung weitere Informationen enthalten können.Accordingly, the invention relates to an at least two-layer label for tearing and reclosing flexible packages having a precut, closed with a lid opening.
The label consists of a basic label,
  • the underside of which is provided with a first adhesive layer, which is optionally covered with a release paper or a separating film until the label has adhered,
  • in which a cutout is provided whose connection with the rest of the basic label is weakened or severed,
    and with a cover label,
  • whose underside is equipped with a second adhesive layer, by means of which the cover label is glued to the base label,
wherein the bond strength of the base label to the base on which the label is adhered is higher than the bond strength of the cover label on the base label, and the bond strength between the cutout and cover label is higher than the force required to hold the lid in the package by means of to separate it from the cutout from the packaging.
At the same time, this adhesive force is higher than the force required to separate the cutout from the base to which the label is glued.
Optionally, further protective labels are provided on the cover label, which may contain further information, for example, in Leporellofaltung.

Das Etikett besteht in einer anderen Ausführungsform der Erfindung aus einem Grundetikett,

  • dessen Unterseite mit einer ersten Klebeschicht ausgerüstet ist, die gegebenenfalls vor der Verklebung des Etiketts mit einem Trennpapier oder einer Trennfolie abgedeckt ist,
  • in dem ein Ausschnitt entfernt worden ist, wobei die sich dadurch im Grundetikett ergebende Öffnung über dem Deckel der Verpackung angeordnet ist,
    und mit einem Decketikett,
  • dessen Unterseite mit einer zweiten Klebeschicht ausgerüstet ist, mittels der das Decketikett auf dem Grundetikett verklebt ist,
wobei die Klebkraft des Grundetiketts auf dem Grund, auf dem das Etikett verklebt ist, höher als die Klebkraft des Decketiketts auf dem Grundetikett ist sowie die Klebkraft zwischen Decketikett und Deckel höher ist als die Kraft, die zum Trennen des Deckels aus der Verpackung erfordelich ist.
Gegebenenfalls sind auf dem Decketikett weitere Schutzetiketten vorgesehen, die beispielsweise in Leporellofaltung weitere Informationen enthalten können.
In diesem Fall wird bei der Herstellung des Etiketts der Ausschnitt aus dem Grundetikett ausgestanzt und entfernt, bevor das Grundetikett und das Decketikett zusammengefügt werden.In another embodiment of the invention, the label consists of a base label,
  • the underside of which is provided with a first adhesive layer, which is optionally covered with a release paper or release film before the label is bonded,
  • in which a cutout has been removed, whereby the opening resulting therefrom in the basic label is arranged above the lid of the packaging,
    and with a cover label,
  • whose underside is equipped with a second adhesive layer, by means of which the cover label is glued to the base label,
wherein the bond strength of the base label to the base on which the label is adhered is higher than the bond strength of the cover label on the base label, and the bond strength between the cover label and the lid is higher than the force required to separate the lid from the package.
Optionally, further protective labels are provided on the cover label, which may contain further information, for example, in Leporellofaltung.
In this case, during the production of the label, the cutout is punched out of the base label and removed before the base label and the cover label are joined together.

Die unterschiedlichen Klebekräfte können dadurch erzielt werden, dass die erste Klebebeschichtung stärker klebend ausgebildet ist als die zweite Klebebeschichtung. In diesem Fall ist sicherzustellen, dass zwischen Ausschnitt und Decketikett wie erforderlich eine ausreichend hohe Klebkraft eingestellt ist, um den Ausschnitt aus dem Grundetikett während des Öffnungsvorgangs erntfernen zu können.The different adhesive forces can be achieved by making the first adhesive coating more adhesive than the second adhesive coating. In this case it is necessary to ensure that between cut-out and cover label, as required, a sufficiently high bond strength is set to be able to remove the cutout from the base label during the opening process.

Das Etikett wird vorzugsweise auf flexiblen Verpackungen mit vorgeschnittener Öffnung wie Schlauchbeutel, in denen sich ölgetränkte Feuchtetücher (bekannt als Baby- oder Schminktücher) befinden, eingesetzt.
In dem Schlauchbeutel ist üblicherweise durch Anstanzungen ein Deckel vorhanden, der derart mit dem Schlauchbeutel verbunden ist, dass dieser Deckel zwar problemlos lösbar, aber auf der anderen Seite luft- und wasserdicht ist. Nach dem Entfernen des Deckels entsteht in dem Beutel eine Öffnung, durch die die Feuchtetücher entnommen werden können.The label is preferably used on pre-cut flexible packages such as tubular bags containing oil-soaked wipes (known as baby or make-up wipes).
In the tubular bag is usually by punching a lid is present, which is so connected to the tubular bag that this cover while easily solvable, but on the other hand is air and waterproof. After removal of the lid, an opening is formed in the bag through which the wipes can be removed.

Das erfindungsgemäße Etikett wird nun auf der Verpackung verklebt, indem zunächst das gegebenenfalls vorhandene Trennpapier von der ersten Klebebeschichtung entfernt wird und dann das Etikett beziehungsweise das Grundetikett mittels der ersten Klebebeschichtung auf der Verpackung fest aufgeklebt wird. Der in dem Grundetikett vorhandene Ausschnitt liegt möglichst deckungsgleich oberhalb des Deckels in der Verpackung. In einer vorteilhaften Ausführungsform der Erfindung hat daher der Ausschnitt im Grundetikett eine größere Fläche auf als der Deckel beziehungsweise die Öffnung in der Verpackung. In der Praxis hat sich erwiesen, dass insbesondere ein überstehender Rand des Ausschnitts von 2 mm Breite hervorragende Ergebnisse liefert.The label according to the invention is then adhesively bonded to the packaging by first removing the optionally present release paper from the first adhesive coating and then firmly adhering the label or the base label to the packaging by means of the first adhesive coating. The existing in the basic label cutout is as congruent above the lid in the package. In an advantageous embodiment of the invention, therefore, the cutout in the base label has a larger area than the lid or the opening in the packaging. In practice, it has been found that in particular a projecting edge of the section of 2 mm width provides excellent results.

In einer weiteren bevorzugten Ausführungsform weist das Decketikett eine größere Fläche auf als das Grundetikett, wobei sich insbesondere ein Abschnitt des Decketiketts über eine Kante des Grundetiketts erstreckt.
In diesem Fall kann bei der Herstellung des Etiketts dieser Abschnitt aus dem Grundetikett ausgestanzt und entfernt werden, bevor das Grundetikett und das Decketikett zusammengefügt werden.
Beim Applizieren des erfindungsgemäßen Etiketts auf der Verpackung kommt der Abschnitt, in dem das Decketikett das Grundetikett überragt, zu einer direkten Verklebung des Decketiketts auf der Verpackung. Auf diese Weise bildet sich ein Scharnier, bis zu dem das Decketikett abgezogen werden kann.In a further preferred embodiment, the cover label has a larger area than the base label, wherein in particular a portion of the cover label extends over an edge of the base label.
In this case, in the manufacture of the label, this portion may be punched out of the base label and removed before assembling the base label and the cover label.
When applying the label according to the invention to the packaging, the section in which the cover label projects beyond the basic label leads to a direct adhesion of the cover label to the packaging. In this way, a hinge forms, up to which the cover label can be removed.

Im Übrigen können erfindungsgemäß weitere Teile im Grundetikett durch Stanzen oder andere Techniken wie Längs- oder Querschneiden abgetrennt werden, bevor das Grundetikett und das Decketikett zusammengefügt werden.Incidentally, according to the invention, further parts in the base label can be separated by punching or other techniques, such as longitudinal or transverse cutting, before the base label and the cover label are joined together.

Weiter vorzugsweise ist zumindest ein weiterer, insbesondere im Kantenbereich des Grundetiketts vorgesehener Abschnitt vorhanden, in dem die Klebkraft zwischen Decketikett und Grundetikett erhöht ist.Further preferably, at least one further, in particular provided in the edge region of the base label section is present in which the bond strength between the cover label and base label is increased.

Dies kann durch den Einsatz von zwei unterschiedlichen Klebstoffen innerhalb der zweiten Klebstoffschicht erreicht werden. Hierzu wird ein ablösbarer, geringe Klebkräfte aufweisender Kleber in dem Bereich eingesetzt, in dem das Decketikett abgezogen werden soll (beim Öffnen der Verpackung). Im Bereich des Abschnitts hingegen wird ein höhere Klebkräfte aufweisender Kleber eingesetzt, um die vollständige Ablösung des Decketiketts zu verhindern.
In einer anderen vorteilhaften Weiterbildung können die Klebkräfte von Teilen der Klebeschichtung herabgesetzt sein, beispielsweise durch Bestrahlung, Bepuderung oder Teilneutralisation.This can be achieved by using two different adhesives within the second adhesive layer. For this purpose, a removable, low adhesive adhesive is used in the area in which the cover label is to be removed (when opening the package). On the other hand, in the area of the section, a higher adhesive adhesive is used to prevent the complete removal of the cover label.
In another advantageous development, the adhesive forces of parts of the adhesive coating may be reduced, for example by irradiation, powdering or partial neutralization.

Das Decketikett, dessen Fläche vorzugsweise deckungsgleich mit dem Grundetikett ausgeführt ist, ist mittels der zweiten Klebeschicht mit dem Grundetikett verklebt.The cover label, whose surface is preferably made congruent with the base label, is glued to the base label by means of the second adhesive layer.

Weiter vorzugsweise ist die Oberseite des Grundetiketts mit Ausnahme der Oberfläche des Ausschnitts abhäsiv. Bevorzugt ist auf der Oberseite des Grundetiketts zumindest ein weiterer, insbesondere im Kantenbereich des Grundetiketts vorgesehener Abschnitt nicht abhäsiv.
Die abhäsive Ausrüstung des Grundetiketts erfolgt vorzugsweise durch Silikonisierung.
Eine andere Möglichkeit besteht darin, einen eine abhäsive Wirkung erzeugenden Lack oder Primer aufzutragen.
So dann kann die Oberfläche des Grundetiketts durch Bestrahlung oder chemischer Behandlung wie Ätzung verändert werden, so dass sich eine abhäsive Wirkung einstellt.More preferably, the top of the base label is abhesive except for the surface of the cutout. At least one is preferred on the upper side of the basic label other, notably abhäsiv provided in particular in the edge region of the basic label section.
The abhesive finish of the base label is preferably siliconized.
Another possibility is to apply a lacquer or primer which produces an abhesive action.
So then the surface of the base label can be changed by irradiation or chemical treatment such as etching, so that sets an abhesive effect.

An den abhäsiven Stellen ist die Ablösung des Decketiketts vom Grundetikett beim Öffnungsvorgang des Etiketts erleichtert. Auf der anderen Seite ist die Verklebung zwischen Grundetikett und Decketikett im nicht abhäsiven Abschnitt fester, so dass ein vollständiges Ablösen des Decketiketts vom Grundetikett nicht zu beobachten ist.At the abhesive areas, the detachment of the cover label from the base label during the opening process of the label is facilitated. On the other hand, the bond between base label and cover label is stronger in the non-abhesive portion, so that complete peeling of the cover label from the base label is not observed.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist auf der Unterseite des Decketiketts an einem Kantenbereich eine Fläche klebemassefrei oder die Klebkraft reduziert. Diese Fläche dient dann als Anfasser zu Abziehen des Decketiketts.
Dieser Anfasser ist vorzugsweise so angeordnet, dass er an einer Kante liegt, die dem nicht abhäsiv ausgerüsteten Abschnitt im Grundetikett gegenüberliegt.
Eine andere Möglichkeit, einen Anfasser herzustellen, besteht darin, die die Fläche bildende Klebemasse durch ein Trennpapier einzudecken, so dass die Klebemasse keine Wirkung entfalten kann. Des Weiteren kann die Klebemasse in diesem Bereich auch neutralisiert sein, beispielsweise durch Bedruckung oder Bepuderung.In a further preferred embodiment of the invention, on the underside of the cover label at an edge region, a surface is free of adhesives or the bond strength is reduced. This area then serves as a handle to peel off the cover label.
This handle is preferably arranged so that it lies on an edge which is opposite to the non-abhesive equipped section in the base label.
Another way to make a handle is to cover the adhesive forming the surface by a release paper, so that the adhesive can have no effect. Furthermore, the adhesive in this area can also be neutralized, for example by printing or powdering.

Durch die abhäsive Ausrüstung des Grundetiketts in Verbindung mit dem geschilderten Anfasser lässt sich das Decketikett einfach abziehen, und zwar bis zu dem Abschnitt des Grundetiketts, der nicht abhäsiv ausgerüstet ist. In diesem Bereich ist die Klebkraft zwischen Deck- und Grundetikett so groß, dass eine Auftrennung nur mit Gewalt möglich ist.
Des Weiteren kann das Decketikett nach Entnahme eines Tuches wieder auf dem Grundetikett reversibel aufgebracht werden, die Restklebkraft hält das Decketikett wiederholt in Position.Due to the adhesive properties of the base label in combination with the described handle, the cover label can simply be peeled off, up to the section of the basic label which is not equipped with an adhesive. In this area, the bond strength between the cover label and the base label is so great that separation is only possible by force.
Furthermore, the cover label can be reversibly applied to the basic label after removal of a cloth, the residual adhesive holds the cover label repeatedly in position.

In einer weiteren vorteilhaften Ausführungsform weist daher das Decketikett im Bereich des nicht abhäsiven Abschnitts des Grundetiketts eine Schwächungslinie auf, sprich am Übergang der permanenten Verbindung zur ablösbaren Verbindung.
Diese Schwächungslinie kann eine Perforation sein, gegebenenfalls in der bekannten und bewährten Wellenform. Durch diese werden die Rückstellkräfte des Decketiketts reduziert, und das Etikett fällt so nicht (zumindest nicht so leicht) zurück, das heißt, die Packung bleibt geöffnet, ohne dass man eine Hand zum Offenhalten benötigte.In a further advantageous embodiment, therefore, the cover label has a weakening line in the region of the non-abhesive section of the base label, that is to say at the transition of the permanent connection to the detachable connection.
This line of weakness may be a perforation, possibly in the known and proven waveform. This reduces the restoring forces of the cover label, and the label does not fall back (at least not so easily), that is, the package remains open without the need for a hand to hold it open.

Während des Öffnungsvorganges des Etiketts überstreicht das Decketikett den Ausschnitt im Grundetikett sowie den in der Verpackung vorgesehenen Deckel. Der Ausschnitt im Grundetikett, dessen Oberseite vorzugsweise nicht abhäsiv ausgerüstet, bleibt am Decketikett quasi hängen. Gleichzeitig wird der Deckel der Verpackung, der fest durch die erste Klebebeschichtung mit dem Abschnitt im Grundetikett verbunden ist, aus seiner Verbindung mit der Verpackung gelöst und gibt die Öffnung frei.During the opening process of the label, the cover label covers the cut-out in the base label and the lid provided in the packaging. The cutout in the base label, the upper side of which is preferably not abhesively fitted, virtually hangs on the cover label. At the same time, the lid of the package, which is firmly connected by the first adhesive coating to the portion in the base label, is released from its connection with the package and releases the opening.

Der Öffnungsvorgang kann soweit fortgesetzt werden, bis die bevorzugt vorhandene Schwächungslinie erreicht ist, an der die Verklebung von der lösbaren und die feste Ausführung übergeht.The opening process can be continued until the preferred existing weakening line is reached, at which the bonding of the detachable and the fixed version passes.

Die Ober- und Unterseite des Decketiketts können bedruckt sein, müssen aber nicht. Das Grundetikett kann ebenfalls bedruckt sein.The top and bottom of the cover label may be printed but not necessarily. The basic label can also be printed.

Die Vorteile des erfindungsgemäßen Etiketts insbesondere in bevorzugten Ausführungsformen sind wie folgt dargestellt.The advantages of the label according to the invention, in particular in preferred embodiments, are shown as follows.

Die Fertigung eines Anfassers durch Nichtbeschichten mit Klebemasse macht eine nachträgliche Neutralisation überflüssig. Selbstverständlich kann es im Einzelfall aber von Vorteil sein, das Decketikett auch im Bereich des Anfassers mit Klebemasse zu beschichten und diese nachträglich zu neutralisieren oder zu schwächen durch teilweise Neutralisation.
Das Etikett lässt sich leicht öffnen, da es nicht von der Verpackung(sfolie) abgezogen wird, sondern das Decketikett vom Grundetikett.
Dennoch ist eine sichere Verklebung auf der Verpackung gewährleistet durch das Grundetikett.The production of a handle by non-coating with adhesive makes a subsequent neutralization superfluous. Of course, it may be advantageous in individual cases to coat the cover label in the area of the handle with adhesive and to neutralize or weaken this by partial neutralization.
The label is easy to open, as it is not peeled from the packaging (foil), but the cover label from the base label.
Nevertheless, a secure bonding on the packaging is guaranteed by the basic label.

Im Gegensatz zu einschichtigen Etiketten, bei denen die Klebkraft ein Kompromiss zwischen Wiederverschließen und Öffnen sein muss, so dass aus der Verpackung austretende Flüssigkeiten wie Öl die Funktionsfähigkeit des sowieso schon schwachen Klebers und damit des Etiketts erheblich reduzieren, kann beim erfindungsgemäßen Etikett das Öl nur bedingt schädigen. Der Kleber, der das Grundetikett auf der Verpackung fixiert, entwickelt ausreichend hohe Webkräfte, so dass Öl keine entscheidende Reduzierung bewirken.
Es ist keine Wölbung des Etiketts zu beobachten. Des Weiteren sind drei Seiten (Ober- und Unterseite des Decketiketts sowie Oberseite des Grundetiketts) bedruckbar, das heißt, es sind vielmehr Informationen verfügbar als bisher.In contrast to single-layer labels, where the bond strength must be a compromise between reclosure and opening, so that emerging from the packaging liquids such as oil significantly reduce the functionality of the already weak adhesive and thus the label, the label according to the invention, the oil only partially damage. The glue that fixes the base label on the packaging, develops sufficiently high weaving forces so that oil does not cause any significant reduction.
There is no curvature of the label to watch. Furthermore, three pages (top and bottom of the cover label and top of the basic label) are printable, that is, it is rather information available than before.

Als Trägermaterialien des Deck- respektive Grundetiketts stehen Papiere oder verschiedene Folien zur Auswahl.
Erfindungsgemäß als Materialien lassen sich Folien einsetzen, insbesondere monoaxial und biaxial gereckte Folien auf Basis von Polyolefinen, dann Folien auf Basis von gerecktem Polyethylen oder gereckten Copolymeren, enthaltend Ethylen- und/oder Polypropyleneinheiten, gegebenenfalls auch PVC-Folien, PET-Folien, Folien auf Basis von Vinylpolymeren, Polyamiden, Polyester, Polyacetalen, PolycarbonatenAs support materials of the cover or base label papers or different films are available.
According to the invention can be used as materials films, in particular monoaxially and biaxially oriented films based on polyolefins, then films based on stretched polyethylene or stretched copolymers containing ethylene and / or polypropylene units, optionally also PVC films, PET films, films Base of vinyl polymers, polyamides, polyesters, polyacetals, polycarbonates

Auch Folien auf Basis von gerecktem Polyethylen oder gereckten Copolymeren, enthaltend Ethylen- und/oder Polypropyleneinheiten, lassen sich erfindungsgemäß einsetzen.Also films based on stretched polyethylene or stretched copolymers containing ethylene and / or polypropylene units can be used according to the invention.

Monoaxial gerecktes Polypropylen zeichnet sich durch seine sehr hohe Reißfestigkeit und geringe Dehnung in Längsrichtung aus. Bevorzugt zur Herstellung der erfindungsgemäßen Etiketten sind monoaxial gereckte Folien auf Basis von Polypropylen. Die Dicken der monoaxial gereckten Folien auf Basis von Polypropylen liegen bevorzugt zwischen 20 und 100 µm, besonders zwischen 25 und 65 µm, ganz besonders zwischen 30 und 60 µm.
Monoaxial gereckte Folien sind überwiegend einschichtig, grundsätzlich können aber auch mehrschichtige monoaxial gereckte Folien hergestellt werden. Bekannt sind überwiegend ein-, zwei- und dreischichtige Folien, wobei die Anzahl der Schichten auch größer gewählt werden kann.Monoaxially stretched polypropylene is characterized by its very high tensile strength and low elongation in the longitudinal direction. Preferred for the production of labels according to the invention are monoaxially stretched films based on polypropylene. The thicknesses of the monoaxially stretched films based on polypropylene are preferably between 20 and 100 μm, in particular between 25 and 65 μm, very particularly between 30 and 60 μm.
Monoaxially oriented films are predominantly single-layered, but in principle it is also possible to produce multilayer monoaxially stretched films. Are known predominantly one, two and three-layer films, the number of layers can also be chosen larger.

Die Dicken der biaxial gereckten Folien auf Basis von Polypropylen liegen insbesondere zwischen 12 und 100 µm, besonders zwischen 20 und 75 µm, ganz besonders zwischen 30 und 60 µm.The thicknesses of the biaxially oriented films based on polypropylene are in particular between 12 and 100 μm, in particular between 20 and 75 μm, very particularly between 30 and 60 μm.

Biaxial gereckte Folien auf Basis von Polypropylen können mittels Blasfolienextrusion oder mittels üblicher Flachfolienanlagen hergestellt werden. Biaxial gereckte Folien werden sowohl ein- als auch mehrschichtig hergestellt. Im Falle der mehrschichtigen Folien können auch hier die Dicke und Zusammensetzung der verschiedenen Schichten gleich sein aber auch verschiedene Dicken und Zusammensetzungen sind bekannt.Biaxially oriented films based on polypropylene can be produced by blown film extrusion or by means of conventional flat film systems. Biaxially stretched films are produced in one or more layers. In the case of multilayer films, the thickness and composition of the different layers may be the same, but also different thicknesses and compositions are known.

Besonders bevorzugt für die erfindungsgemäßen Etiketten sind einschichtige, biaxial oder monoaxial gereckte Folien und mehrschichtige, biaxiale oder monoaxiale Folien auf Basis von Polypropylen, die einen ausreichend festen Verbund zwischen den Schichten aufweisen, da ein Delaminieren der Schichten während der Anwendung nachteilig ist.Particularly preferred for the labels of the invention are monolayer, biaxially or monoaxially stretched films and multilayer, biaxial or monoaxial polypropylene-based films which have a sufficiently strong bond between the layers, since delamination of the layers during use is disadvantageous.

Folien auf Basis von Hart-PVC werden zur Herstellung von Etiketten ebenso verwendet wie Folien auf Basis von Weich-PVC.
Für die erfindungsgemäßen Etiketten werden dann üblicherweise Folien verwendet auf Basis von Hart-PVC. Die Dicken der Folien liegen bevorzugt zwischen 20 und 100 µm, besonders zwischen 25 und 65 µm, ganz besonders zwischen 30 und 60 µm.Films based on rigid PVC are used for the production of labels as well as films based on soft PVC.
For the labels according to the invention then usually films are used based on rigid PVC. The thicknesses of the films are preferably between 20 and 100 μm, in particular between 25 and 65 μm, very particularly between 30 and 60 μm.

Folien auf Polyesterbasis, zum Beispiel Polyethylenterephthalat sind ebenfalls bekannt und können ebenso zur Herstellung der erfindungsgemäßen Etiketten eingesetzt werden. Die Dicken der Folien auf Basis von PET liegen zwischen 20 und 100 µm, besonders zwischen 25 und 65 µm, ganz besonders zwischen 30 und 60 µm.Polyester-based films, for example polyethylene terephthalate, are also known and can also be used to make the labels of the invention. The thicknesses of the films based on PET are between 20 and 100 μm, in particular between 25 and 65 μm, very particularly between 30 and 60 μm.

Die erfindungsgemäßen Etiketten können als Klebemassen eine Klebemasse auf Basis von Naturkautschuk, PUR, Acrylaten oder Styrol-Isopren-Styrol-Blockcolymeren enthalten.The labels according to the invention may contain as adhesives an adhesive based on natural rubber, PUR, acrylates or styrene-isoprene-styrene block copolymers.

Die Verwendung von Klebemassen auf Basis von Naturkautschuk, Acrylaten oder Styrol-Isopren-Stryrol ist bekannt, was auch zum Beispiel im " Handbook of pressure sensitive adhesive technologie, second edition, herausgegeben durch Donatas Satas, Van Nostrand Reinhold, New York, 1989 beschrieben wird.The use of adhesives based on natural rubber, acrylates or styrene-isoprene-styrene is known, which is also known, for example, in US Pat. Handbook of pressure-sensitive adhesive technology, second edition, edited by Donatas Satas, Van Nostrand Reinhold, New York, 1989 is described.

Als selbstklebende Masse kommt insbesondere eine handelsübliche druckempfindliche Klebmasse auf PUR, Acrylat- oder Kautschukbasis zum Einsatz.The self-adhesive composition used is in particular a commercially available pressure-sensitive adhesive based on PUR, acrylate or rubber.

Anhand der nachfolgend beschriebenen Figuren wird ein Etikett in einer besonders vorteilhaften Ausführung näher erläutert, ohne damit die Erfindung unnötig einschränken zu wollen.With reference to the figures described below, a label is explained in more detail in a particularly advantageous embodiment, without thereby wanting to limit the invention unnecessarily.

FIG. 2
the split label according to section line AA FIG. 1 that has torn open the lid of the tubular bag, and
FIG. 3
similar to the split label FIG. 2 ,

Gemäß Figur 1 besteht das Etikett 1 aus einem Grundetikett 3, dessen Unterseite mit einer ersten Klebeschicht ausgerüstet ist (nicht dargestellt). In dem Grundetikett 3 ist ein Ausschnitt 31 vorgesehen, dessen Verbindung mit dem übrigen Grundetikett 3 geschwächt ist. Die Oberseite ist durch Silikonbeschichtung abhäsiv, wobei der Ausschnitt 31 sowie ein weiterer, im Kantenbereich des Grundetiketts 3 vorgesehener Abschnitt 32 nicht abhäsiv sind.
Das Decketikett 2 (das zwecks verbesserter Darstellung aufgeklappt ist) ist unterseitig mit einer zweiten Klebeschicht ausgerüstet (ebenfalls nicht dargestellt).
Das Decketikett 2, dessen Fläche deckungsgleich mit dem Grundetikett 3 ausgeführt ist, ist mittels der zweiten Klebeschicht mit dem Grundetikett 3 an den Stellen lösbar verklebt, an denen das Grundetikett 3 auf seiner Oberseite abhäsiv ausgerüstet ist.According to FIG. 1 the label 1 consists of a base label 3, the underside of which is equipped with a first adhesive layer (not shown). In the basic label 3, a cutout 31 is provided, whose connection with the rest of the basic label 3 is weakened. The upper side is adhesive by silicone coating, wherein the cutout 31 and another, provided in the edge region of the base label 3 section 32 are not abhesive.
The cover label 2 (which is unfolded for the purpose of improved illustration) is equipped on the underside with a second adhesive layer (also not shown).
The cover label 2, whose surface is made congruent with the base label 3, is adhesively bonded by means of the second adhesive layer to the base label 3 at the points where the base label 3 is provided abhesively on its upper side.

Das Etikett 1 wird unter Verwendung der ersten Klebebeschichtung auf dem Grundetikett 3 auf einen Schlauchbeutel 4 aufgeklebt, wobei im Schlauchbeutel 4 ein Deckel 41 vorhanden ist, der derart mit dem Schlauchbeutel 4 verbunden ist, dass dieser Deckel 41 zwar problemlos lösbar, aber auf der anderen Seite luft- und wasserdicht ist.
In dem Schlauchbeutel 4 befinden sich beispielsweise ölgetränkte Feuchtetücher (bekannt als Baby- oder Schminktücher).The label 1 is adhered using the first adhesive coating on the basic label 3 on a tubular bag 4, wherein in the tubular bag 4, a lid 41st is present, which is so connected to the tubular bag 4, that this cover 41 while easily solvable, but on the other hand is air and waterproof.
In the tubular bag 4 are, for example, oil-soaked wipes (known as baby or make-up wipes).

Der in dem Grundetikett 3 vorhandene Ausschnitt 31 liegt deckungsgleich oberhalb des Deckels 41 in dem Schlauchbeutel 4.
Der Ausschnitt 31 weist eine etwas größere Fläche auf als der Deckel 41.The present in the basic label 3 cutout 31 is congruent above the lid 41 in the tubular bag. 4
The cutout 31 has a slightly larger area than the lid 41.

Auf der Unterseite des Decketiketts 2 ist eine Fläche 21 an einem Kantenbereich klebemassefrei. Diese Fläche 21 dient dann als Anfasser zu Abziehen des Decketiketts 2.On the underside of the cover label 2, a surface 21 is adhesive-free at an edge region. This surface 21 then serves as a handle for removing the cover label. 2

Durch die abhäsive Ausrüstung des Grundetiketts 3 lässt sich das Decketikett 2 einfach abziehen, und zwar bis zu dem Abschnitt 32 des Grundetiketts 3 der nicht abhäsiv ausgerüstet ist. In diesem Bereich (22, 32) ist die Klebkraft zwischen Decketikett 2 und Grundetikett 3 so groß, dass eine Auftrennung nur mit Gewalt möglich ist.By abhesive equipment of the base label 3, the cover label 2 can be easily removed, up to the section 32 of the base label 3 which is not abhesive equipped. In this area (22, 32), the bond between cover label 2 and base label 3 is so great that separation is only possible by force.

Im Bereich des nicht abhäsiven Abschnitts (22, 32) des Grundetiketts 3 weist das Decketikett 2 eine Schwächungslinie 23 auf, sprich am Übergang der permanenten Verbindung zur ablösbaren Verbindung.In the region of the non-abhesive portion (22, 32) of the base label 3, the cover label 2 has a weakening line 23, that is to say at the transition from the permanent connection to the detachable connection.

In Figur 2 ist das aufgetrennte Etikett 1 gemäß Schnittlinie A-A aus Figur 1 gezeigt, das den Deckel 41 des Schlauchbeutels 4 aufgerissen hat.
Von dem Schlauchbeutel 4 ist nur die obere Lage gezeigt. Durch das Ziehen am Anfasser 21 überstreicht das Decketikett 2 den Ausschnitt 31 im Grundetikett 3 sowie den im Schlauchbeutel 4 vorgesehenen Deckel 41. Der Ausschnitt 31 im Grundetikett 3, dessen Oberseite nicht abhäsiv ausgerüstet, bleibt am Decketikett 2 quasi hängen. Gleichzeitig wird der Deckel 41, der fest durch die erste Klebebeschichtung mit dem Abschnitt 31 im Grundetikett 3 verbunden ist, aus seiner Verbindung gelöst und gibt die Öffnung im Schlauchbeutel 4 frei.
Gleichzeitig werden die Haltepunkte, mit denen der Ausschnitt 31 im Grundetikett 3 fixiert ist, durchtrennt, so dass letztendlich sich unter dem Decketikett 2 der Ausschnitt 31 aus dem Grundetikett 3 sowie auf diesem der Deckel 41 befinden.In FIG. 2 is the separated label 1 according to section line AA FIG. 1 shown that has torn open the lid 41 of the tubular bag 4.
Of the tubular bag 4, only the upper layer is shown. By pulling on the handle 21, the cover label 2 sweeps over the cutout 31 in the base label 3 as well as the cover 41 provided in the tubular bag 4. The cutout 31 in the base label 3, the top of which is not abhesively fitted, virtually remains hanging on the cover label 2. At the same time, the lid 41, which is firmly connected by the first adhesive coating to the section 31 in the base label 3, is released from its connection and releases the opening in the tubular bag 4.
At the same time, the holding points with which the cutout 31 is fixed in the base label 3 are severed, so that ultimately the cutout 31 from the base label 3 and the lid 41 are located under the cover label 2.

Der Öffnungsvorgang wird soweit fortgesetzt, bis die Schwächungslinie 23 erreicht ist, an der die Verklebung von der lösbaren und die feste Ausführung übergeht.The opening process is continued until the line of weakness 23 is reached, at which the bond passes from the detachable and the fixed execution.

In Figur 3 ist ein aufgetrenntes Etikett 1 ähnlich Figur 2 dargestellt.
Das Decketikett 2 weist eine größere Fläche auf als das Grundetikett 3, wobei sich ein Abschnitt 25 des Decketiketts 2 über eine Kante des Grundetiketts 3 erstreckt.
Beim Applizieren des erfindungsgemäßen Etiketts 1 auf dem Schlauchbeutel 4 kommt der Abschnitt 25, in dem das Decketikett 2 das Grundetikett 3 überragt, zu einer direkten Verklebung des Decketiketts 2 auf dem Schlauchbeutel 4. Auf diese Weise bildet sich ein Scharnier, bis zu dem das Decketikett 2 abgezogen werden kann.In FIG. 3 is a split label 1 similar FIG. 2 shown.
The cover label 2 has a larger area than the base label 3, with a portion 25 of the cover label 2 extending over an edge of the base label 3.
When applying the label 1 according to the invention on the tubular bag 4, the section 25, in which the cover label 2 projects beyond the base label 3, comes to a direct bonding of the cover label 2 on the tubular bag 4. In this way, a hinge is formed, up to which the cover label 2 can be deducted.
