Description
Die Erfindung betrifft einen Beutel, insbesondere einen Verpackungsbeutel für Lebensmittel, mit einer Vorderwand und einer Rückwand und einem auf mindestens einer Innenseite der Vorderwand oder Rückwand aufgebrachten Klebestreifen, wobei der Klebestreifen im unverechlossenen Zustand des Beutels mit einem Schutzstreifen abgedeckt ist und Seitenschweißnähten, die sich von einem unteren Ende des Beutels bis an den Schutzstreifen heran erstrecken, und mit den weiteren Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a bag, in particular a food packaging bag, having a front wall and a rear wall and an adhesive strip applied to at least one inside of the front wall or rear wall, wherein the adhesive strip is covered with a protective strip in the unclosed state of the bag and side welds extending from a lower end of the bag extend up to the protective strip, and with the further features of the preamble of claim 1.
In vielen Bereichen des täglichen Lebens werden Beutel zum Verpacken von Gütern eingesetzt. Je nach verpacktem Gut werden hierbei unterschiedliche Anforderungen an die Beutel gestellt. Wesentlich für den Transport ist hierbei der Verschluss des Beutels. Die Erfindung bezieht sich auf Beutel, die mit einem Klebestreifen versehen sind, so dass die Beutelwände zum Verschließen einer Einfüllöffnung des Beutels mit einander verklebbar sind. Zur Lagerung und zur leichteren Handhabung der Beutel sind die Klebestreifen zumeist mit einem Schutzstreifen versehen, der vor dem Verkleben der Wände oder Klebestreifen miteinander entfernt wird. Je nach Einsatzzweck und Verwendung der Verpackungsbeutel bestehen die Beutel aus Kunststoff, Papier oder aus mit Kunststoff beschichtetem Papier.In many areas of daily life, bags are used to package goods. Depending on the packaged goods, different requirements are placed on the bags. Essential for the transport here is the closure of the bag. The invention relates to bags which are provided with an adhesive strip, so that the bag walls for closing a filling opening of the bag are glued together. For storage and easier handling of the bags, the adhesive strips are usually provided with a protective strip, which is removed before bonding the walls or tape together. Depending on the purpose and use of the packaging bag, the bags are made of plastic, paper or plastic-coated paper.
Ein mittels eines Klebestreifens verschließbarer Beutel ist in der
Ein weiterer Beutel ist In der
Ein Problem, das sich bei derartigen Beuteln ergibt, ist das, dass die Beutel zwar ein sicheres Verpacken und Transportieren des eingebrachten Gutes ermöglichen, die Beutel das verpackte Gut aber nicht flüssigkeitsdicht transportieren können. Insbesondere in den Fällen, In denen in den Beuteln zum Beispiel Lebensmittel transportiert oder verpackt werden ist es möglich, dass, zum Beispiel bei Gefrierprodukten Wasser im Beutel vorhanden ist. In diesem Fall ist es notwendig, dass der Beutel flüsslgkeltadicht verschließbar ist. Gemäß der
Aus der
Aufgabe der Erfindung ist es, einen Beutel zu entwickeln, der das Verpackungsgut flüssigkeitsdicht einschließt und der darüber hinaus mit geringen konstruktiven Mitteln und kostengünstig herstellbar ist.The object of the invention is to develop a bag which encloses the packaged liquid-tight and which is also inexpensive to produce with low design means and.
Diese Aufgabe wird durch einen Beutel gemäß Anspruch 1 gelöst. Durch die erfindungsgemäβe Ausbildung des Schutzstreifens ist nun die Möglichkeit geschaffen, ein Verpackungsgut mit einem mit einem Klebestreifen versehenen Verpackungsbeutel flüssigkeitsdicht einzuschließen. Der aus dem Stand der Technik bekannte Nachteil, dass der Schutzstreifen über den Klebestreifen hinausragt und somit ein vollständiges Verschließen eines Verpackungsbeutels verhindert, ist somit überwunden. Der Schutzstreifen, der zum Beispiel ein Papierstreifen ist, besitzt eine Aussparung, die sich etwa aus einem mittleren Bereich der Schweißnaht heraus In Richtung des Klebestreifens und In Richtung des seitlichen Rands des Beutels erstreckt. Die Seitenschweißnähte reichen somit zumindest bis an den Klebestreifen heran, so dass nach einem Abziehen des Schutzstreifens der Beutel lückenlos mittels eines Zusammenfügens der Vorderseite und der Rückseite des Beutels flüssigkeitsdicht verschließbar ist. Die Aussparung im Schutzstreifen beginnt in einem mittleren Bereich der Schweißnähte und erstreckt sich linear und/oder mit bogenförmigen und/oder kreisförmigen Abschnitten in Richtung des seitlichen Endes des Beutels. Dies bietet einerseits den Vorteil, dass der Schutzstreifen leichter zwischen der Vorderwand und Rückwand des Beutels herausziehbar ist und andererseits den Vorteil, dass ein Öffnen des Beutels leichter möglich ist.This object is achieved by a bag according to claim 1. By erfindungsgemäβe training of the protective strip, the possibility is now created to include a packaged with a liquid provided with an adhesive packaging bag. The disadvantage known from the prior art that the protective strip protrudes beyond the adhesive strip and thus prevents a complete closing of a packaging bag is thus overcome. The protective strip, which is for example a strip of paper, has a recess which extends approximately from a central region of the weld in the direction of the adhesive strip and in the direction of the lateral edge of the bag. The side welds thus reach at least as far as the adhesive strip, so that after peeling off the protective strip, the bag can be closed in a liquid-tight manner by means of an assembly of the front side and the back side of the bag. The recess in the protective strip begins in a central area the welds and extends linearly and / or with arcuate and / or circular portions in the direction of the lateral end of the bag. On the one hand, this offers the advantage that the protective strip is more easily pulled out between the front wall and the rear wall of the bag and, on the other hand, has the advantage that it is easier to open the bag.
Ein weiterer Vorteil ergibt sich erfindungsgemäß dadurch, dass sich die Schweißnähte bis in einen Bereich des Klebestreifens hineinerstrecken, das heißt, die Aussparung im Schutzβtrei fen legt einen Teil des Klebestreifens zum Verschweißen der Vorderwand und Rückwand frei. Hierdurch wird eine noch größere Sicherheit In Bezug auf das flüssigkeitsdichte Verschließen des Beutels erreicht.Another advantage results according to the invention in that the welds hineinerstrecken into a region of the adhesive strip, that is, the recess in the Schutzβtrei fen sets a portion of the adhesive strip for welding the front wall and back wall free. As a result, an even greater security with regard to the liquid-tight sealing of the bag is achieved.

Bevor in einem nächsten Verfehtensachritt der Schutzstreifen auf die Bahn 2 aufgebracht wird, wird rapportgenau eine Aussparung in Form einer Einstanzung 6, 7 in den Schutzstreifen eingebracht. Rapportgenau bedeutet hierbei, dass die Einstanzungen 6, 7 exakt passend zur Breite der fertigen Beutel in den Schutzstreifen eingebracht werden. In dem mit I bezeichneten Verfahrensschritt ist lediglich die Leimspur 4, 5 auf die Bahn 2 aufgetragen und das Loch 3 eingestanzt. In dem mit II bezifferten Verfahrensschritt ist der mit der Aussparung 6, 7 versehene Schutzstreifen 8, 9 auf den Klebestreifen aufgebracht. Die Aussparung 6, 7 liegt in der grobschematischen Darstellung der Verfahrensschritte einen Tell der Leimspur 4, 5 frei.Before the protective strip is applied to the
Der Verfahrensschritt III zeigt die beidseitig zusammengefaltete Flachbahn 2, so dass eine Vorderwand und eine Rückwand gebildet ist. Als Vorderwand wird hierbei die auf die Flachbahn gefaltete Seite bezeichnet. Deutlich zu erkennen ist, dass durch die Aussparung 6, 7 ein Teil des Klebestreifens 4, 5 freigelegt wird, so dass eine im Verfahrensschritt IV eingebrachte Schweißnaht, zur Bildung der Seltenschweißnähte 10, 11 bis in den Bereich des Klebestreifens 4, 5 reicht. Wird die Flachbahn 2 aus einer Papierbahn gebildet, so sind zumindest die sich gegenüberliegenden Seiten der Vorderwand und Rückwand mit einem thermoplastischen Kunststoff beschichtet, so dass ein Verschweißen der Seitenwände 6, 7 ermöglicht wird.Process step III shows the
