Abstract

A method for producing a package from a film (4) or the like which is printed and provided with a perforation (12) to facilitate opening of the package. Said perforation (12) is effected in the printing machine and is subsequently closed by a covering layer (13) or lamination. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer Verpackung aus einer Folie, die in einer Druckmaschine bedruckt und zum Erleichtern des Öffnens der Verpackung mit einer Perforation versehen wird.The invention relates to a method for producing a packaging from a film, which is printed in a printing press and provided with a perforation to facilitate opening of the packaging.

Beispielsweise bei Verpackungen für Papiertaschentücher sind derartige Perforierungen bekannt, die ein Aufreißen der Verpackung ganz erheblich erleichtern. Sind die verpackten Taschentücher jedoch mit Duftstoffen versehen, so sind derartige Perforierungen nachteilig, da die Duftstoffe entweichen können und zum einen verlorengehen und zum anderen die Umgebung ungewollt beeinträchtigen.For example, in the case of packaging for paper handkerchiefs, perforations of this type are known which make it considerably easier to tear open the packaging. However, if the packaged handkerchiefs are provided with fragrances, perforations of this type are disadvantageous because the fragrances can escape and, on the one hand, get lost and, on the other hand, undesirably impair the environment.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zu schaffen, mit dem eine Verpackung hergestellt werden kann, die sowohl leicht zu öffnen ist, als auch dicht verschlossen werden kann.The invention has for its object to provide a method with which a package can be produced that is both easy to open and can be sealed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Perforieren ebenfalls in der Druckmaschine erfolgt und die Perforierung durch Anbringen einer Beschichtung oder Kaschierung verschlossen wird.This object is achieved in that the perforation also takes place in the printing press and the perforation is closed by applying a coating or lamination.

Mit diesem Verfahren ist ein äußerst exaktes und rationelles Perforieren gewährleistet, wobei die durch das Perforieren entstandenen Undichtigkeiten darstellenden Löcher im weiteren Verfahrensablauf wieder verschlossen werden. Die Wirkung der Perforation als Öffnungshilfe wird durch dieses Abdecken jedoch nicht wesentlich beeinflußt.This method ensures extremely precise and efficient perforation, the holes representing leaks resulting from the perforation being closed again in the further course of the method. The effect the perforation as an opening aid is not significantly affected by this covering.

Bei einer erfindungsgemäßen Weiterbildung dieses Verfahrens, bei dem die Folie in einer Rotationsdruckmaschine mit Hilfe von Druckzylindern bedruckt wird, ist vorgesehen, daß einer der Zylinder der Druckmaschine, vorzugsweise der letzte, mit einer Perforiervorrichtung versehen ist, wodurch die Folie beim bzw. im unmittelbaren Anschluß an das Bedrucken perforiert wird, und daß die Perforierung durch eine wenigstens partiell aufgebrachte Beschichtung oder Kaschierung abgedeckt wird.In a further development of this method according to the invention, in which the film is printed in a rotary printing press with the aid of printing cylinders, it is provided that one of the cylinders of the printing press, preferably the last one, is provided with a perforating device, as a result of which the film is connected to or in the immediate vicinity perforated to the printing, and that the perforation is covered by an at least partially applied coating or lamination.

Bei dieser Ausgestaltung ist durch die Verwendung eines der Zylinder der Druckmaschine zum Perforieren eine exakte Lage der Perforierlinie im Verhältnis zum Druckbild auf einfache Weise gewährleistet.In this embodiment, an exact position of the perforation line in relation to the printed image is ensured in a simple manner by using one of the cylinders of the printing press for perforating.

Die Erfindung ist in der Zeichnung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

  • Fig. 1 eine schematische Darstellung einer Druckmaschine mit mehreren Druckzylindern sowie einem Zylinder mit Perforiereinrichtung,
  • Fig. 2 einen Abschnitt des auf der Druckmaschine bedruckten und perforierten Materials im Querschnitt und
  • Fig. 3 eine schaubildliche Darstellung einer aus diesem Material hergestellten Verpackung.
The invention is illustrated in the drawing using an exemplary embodiment. Show:
  • 1 is a schematic representation of a printing press with several printing cylinders and a cylinder with perforating device,
  • Fig. 2 shows a section of the material printed and perforated on the printing machine in cross section and
  • Fig. 3 is a perspective view of a packaging made from this material.

Mit 1 ist in Fig. 1 eine Druckmaschine bezeichnet, die mehrere Führungswalzen 2 und Gegendruckwalzen 3 aufweist, über welche eine Folienbahn 4 läuft. Den Gegendruckwalzen 3 gegenüberliegend sind Druckzylinder 5 angeordnet zum Aufdrucken beliebiger Informationen auf die Folienbahn 4.1 in FIG. 1 denotes a printing press which has a plurality of guide rollers 2 and counter-pressure rollers 3, over which a film web 4 runs. Printing cylinders 5 are arranged opposite the impression rollers 3 for printing any information on the film web 4.

Im Anschluß an den letzten Druckzylinder ist eine Walze 6 angeordnet, die mit einer Perforiereinrichtung 7 versehen ist und mit einer Gegenwalze 8 zusammenarbeitet. Zwischen diesen beiden Walzen läuft die Folienbahn 4 durch und wird perforiert.Following the last pressure cylinder, a roller 6 is arranged, which is provided with a perforating device 7 and cooperates with a counter roller 8. The film web 4 runs between these two rollers and is perforated.

Unmittelbar hinter dieser Perforier-Walze 6 gelangt die Folienbahn zu einer weiteren Führungswalze 9, der eine Extruderdüse 10 zugeordnet ist, aus welcher die Folienbahn 4 mit einer weiteren Kunststoffschicht beschichtet wird.Immediately behind this perforating roller 6, the film web arrives at a further guide roller 9, to which an extruder nozzle 10 is assigned, from which the film web 4 is coated with a further plastic layer.

In Fig. 2 ist eine Bahn 14 gezeigt, die aus einer Folie 4 besteht, die mit einer aufgedruckten Information 11 sowie einer Perforation 12 versehen ist. Diese Folie 4 ist auf der bedruckten Seite mit einer aufextrudierten Kunststoffschicht 13 versehen.In Fig. 2 a web 14 is shown, which consists of a film 4, which is provided with a printed information 11 and a perforation 12. This film 4 is provided on the printed side with an extruded plastic layer 13.

Dabei kann die Folienbahn 4 sowohl aus Kunststoff als auch aus Papier, Aluminium oder anderem gebildet sein.The film web 4 can be formed both from plastic and from paper, aluminum or other.

Die einfachste Art der Abdeckung der Perforation erfolgt, wie in Fig. 1 dargestellt, durch Aufextrudieren einer Kunststoffschicht. Es ist aber auch möglich, die Abdeckung durch Aufkaschieren einer weiteren Folie aus Kunststoff vorzunehmen.The simplest way of covering the perforation, as shown in FIG. 1, is by extruding a plastic layer. However, it is also possible to cover it by laminating on another plastic film.

Erfolgt das Aufkaschieren auf der vom Druck abgewandten Seite, so ist es auch möglich, eine undurchsichtige Bahn aufzubringen.If the lamination is carried out on the side facing away from the print, it is also possible to apply an opaque web.

In Fig. 3 ist eine fertige Verpackung 24 dargestellt, die durch Siegelnähte 25 verschlossen ist. Quer über die Verpackung verläuft die Perforation 12, entlang der die Verpackung durch einfaches Ziehen an den Enden geöffnet werden kann.A finished packaging 24 is shown in FIG. 3, which is closed by sealing seams 25. The perforation 12 runs across the packaging, along which the packaging can be opened by simply pulling the ends.
