Abstract

Ein mit wenigstens einer Überlappungsklebenaht versehener Papierbeutel (1) ist innenseitig, ausgenommen an den Klebenahtbereichen, mit einer nichthaftenden Beschichtung versehen. Zu seiner Herstellung dient ein entsprechend beschichteter Zuschnitt (2).

Description

Die Erfindung bezieht sich auf Papierbeutel mit wenigstens einer Ueberlappungsklebenaht.The invention relates to paper bags with at least one overlap adhesive seam.

Bei der Verwendung von Papierbeuteln dieser Art in Mikrowellenöfen verklebt das Papier sich manchmal mit dem Inhalt, besonders wenn dieser Stärke- bzw. Eiweissprodukte umfasst. Beim Oeffnen der Beutel nach dem Aufheizen ihres Inhalts bleiben dann häufig Papierstücke auf dem Inhalt kleben, was beim Verzehr störend ist.When using paper bags of this type in microwave ovens, the paper sometimes sticks to the contents, especially if it contains starch or protein products. When the bags are opened after their contents have been heated, pieces of paper often stick to the contents, which is annoying when consumed.

Man hat deshalb bereits vorgeschlagen, eine Papiereinlage mit einer nicht-haftenden Beschichtung zwischen dem Papierbeutel und dem Inhalt anzuordnen. Damit sind jedoch ein grösserer Materialverbrauch und eine zusätzliche Verfahrenshandlung verbunden.It has therefore already been proposed to arrange a paper insert with a non-stick coating between the paper bag and the contents. However, this involves a greater consumption of material and an additional procedural action.

Aufgabe der Erfindung ist es, den Beutel der eingangs beschriebenen Art sowie den Zuschnitt zu seiner Herstellung derart zu verbessern, dass auf einfache und relativ billige Weise die oben genannten Nachteile behoben werden.The object of the invention is to improve the bag of the type described above and the cut for its production in such a way that the above-mentioned disadvantages are eliminated in a simple and relatively inexpensive manner.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor, dass der Beutel innenseitig, ausgenommen an den Klebenahtbereichen, mit einer nicht-haftenden Beschichtung versehen ist.To achieve this object, the invention proposes that the inside of the bag, except on the adhesive seam areas, be provided with a non-stick coating.

Mit nicht-haftend wird in dieser Beschreibung abhäsiv oder Haftung-verhindernd verstanden, wie es z.B. von Silikonen bekannt ist.In this description, non-adhesive means abhesive or adhesion-preventing, as it is e.g. of silicones is known.

Nachfolgend werden ein Ausführungsbeispiel eines erfindungsgemässen Papierbeutels und eines zu seiner Herstellung verwendbaren Zuschnittes unter Bezugnahme auf die Zeichnung beschrieben; in dieser zeigen:

  • Fig.l eine perspektivische Ansicht eines erfindungsgemässen Beutels und
  • Fig.2 einen Zuschnitt zur Herstellung eines Beutels nach Fig.l.
An exemplary embodiment of a paper bag according to the invention and a blank that can be used for its production are described below with reference to the drawing; in this show:
  • Fig.l is a perspective view of a bag according to the invention and
  • 2 shows a blank for the production of a bag according to Fig.l.

Der in Fig.l dargestellte, herkömmlich geformte Papierbeutel 1 ist mit einer innenseitigen nicht- haftenden bzw. abhäsiven Beschichtung versehen. Zu diesem Zweck ist der in Fig.2 dargestellte rechteckige Zuschnitt 2 auf einer Seite mit einer solchen Beschichtung versehen, ausgenommen an den Klebenahtbereichen, d.h. an einer etwa im Bereich der Hälfte einer der Seiten 3 des rechteckigen Zuschnittes 2 angeformten Bodenlasche 4 und entlang einer der quer hierzu verlaufenden Seiten 5. Die so gebildeten Aussparungen 6 bzw. 7 in der nicht-haftenden Beschichtung ermöglichen zuverlässige Klebenahtverbindungen 8 bzw. 9 (in Fig.l schraffiert).The conventionally shaped paper bag 1 shown in FIG. 1 is provided with an inside non-adhesive or abhesive coating. For this purpose, the rectangular blank 2 shown in Fig. 2 is provided on one side with such a coating, except on the adhesive seam areas, i.e. on a bottom flap 4 formed approximately in the area of half of one of the sides 3 of the rectangular blank 2 and along one of the sides 5 running transversely thereto. The recesses 6 and 7 thus formed in the non-adhesive coating enable reliable adhesive seam connections 8 and 9 ( hatched in Fig.l).

Bei der dargestellten Ausführungsform ist der Beutel 1 mit zwei Balgfalten versehen, die dadurch gebildet sind, dass der Zuschnitt 2 um parallele Faltlinien 10 einwärts, um dazu parallele Faltlinien 11 auswärts und um weitere dazu parallele Faltlinien 12 wieder einwärts gefaltet werden derart, dass die Beschichtung innen liegt. Dann werden die beiden überlappenden Enden des Zuschnittes miteinander verklebt, indem der nichtbeschichtete Bereich 7 mit Kleber versehen und auf das andere Ende gedrückt wird. Schliesslich wird die grösstenteils nicht beschichtete Bodenlasche 4 umgelegt umd auf den vereinigten Endteilen aufgeklebt.In the embodiment shown, the bag 1 is provided with two bellows folds, which are formed in that the blank 2 is folded inwards by parallel fold lines 10, outwards by parallel fold lines 11 and inwards by further parallel fold lines 12 such that the coating is inside. Then the two overlapping ends of the blank are glued to one another by providing the non-coated area 7 with adhesive and pressing it onto the other end. Finally, the largely non-coated bottom flap 4 is folded over and glued to the combined end parts.
