Verfahren zur Herstellung einer Tasche sowie eine nach dem Verfahren hergestellte TascheMethod for producing a bag and a bag produced by the method
Die vorliegende Erfindung bezieht, sich auf ein Verfahren zur Herstellung einer in ihrer Tiefe verstellbaren Tasche aus einer Folie sowie auf eine nach dem Verfahren hergestellte Tasche bestehend aus zwei rechteckigen folienartigen Taschenwänden, die längs drei ihrer Kanten durch eine feste Verbindung miteinander verbunden sind, wobei eine dieser festen Verbindungen den Taschenboden bildet.The present invention relates to a method for Production of a depth-adjustable pocket from a film and a pocket produced according to the method Bag consisting of two rectangular foil-like bag walls which are connected to one another along three of their edges by a fixed connection, one of these fixed connections forms the bottom of the bag.
Wegwerftaschen sind bekannt. Sie werden von Detailhandelsgeschäften an die Kunden abgegeben, um die eingekauften Waren in transportfähiger Weise zu verpacken. Diese Taschen sind wegen ihrer Tiefe jedoch als Kehrichtsäcke wegen der zu geringen Tiefe nicht verwendbar, da sie hierdurch den Örtlichen Vorschriften der Kehrichtabfuhrorgane nicht entsprechen. Anderseits sind besonders gefertigte Kehrichtsäcke bekannt.Disposable bags are known. They are from retail stores given to the customer in order to pack the purchased goods in a transportable manner. These bags are Due to their depth, however, they cannot be used as garbage bags because they are too shallow, as this makes them more difficult to use Do not comply with the regulations of the waste disposal authorities. On the other hand specially manufactured garbage bags are known.
Das Nebeneinanderbestehen von Wegwerftragtaschen einerseits und Kehrichtsäcken anderseits ist unwirtschaftlich und erhöht den durch die öffentliche Hand zu beseitigenden Kehrichtanfall. Zweck der vorliegenden Erfindung ist die Schaffung einer als Kehrichtsack verwendbaren Tragtasche, um die vorgenannten Nachteile zu beseitigen.The juxtaposition of disposable bags on the one hand and garbage bags, on the other hand, is uneconomical and increases the amount of garbage that has to be disposed of by the public sector. The purpose of the present invention is to create a bag that can be used as a garbage bag to carry the aforementioned Eliminate disadvantages.
Zu diesem Zwecke sieht die Erfindung vor, dass mit Abstand voneinander auf einem Folienhalbschlauch zwischen dem Falz und einer zweiten Falzlinie Trennlackstreifen aufgebracht und in Richtung von der Falzlinie gegen den Falz nacheinander eine durchgehende Verbindungsnaht und eine Perforation aufgebracht werden, dass danach der mit dem Falz versehene Folienhalbschlauchteil um die zweite Falzlinie gefalzt wird, dass danach zwischen der Perforation und dem Falz durch eine durchgehende Verbindungsnaht der umgefalzte Folienhalbschlauchteil am anliegenden Folienblatt befestigt wird, dass danach im Bereich jedes Trennlackstreifens die aufeinanderliegenden Halbschiauch-For this purpose, the invention provides that at a distance from one another applied to a film half tube between the fold and a second fold line separating lacquer strips and in Direction from the fold line against the fold, a continuous connecting seam and a perforation are applied one after the other that then the film half-tube part provided with the crease is folded around the second crease line, that afterwards between the perforation and the fold through a continuous connecting seam of the folded film half-tube part on the adjacent one Foil sheet is attached so that afterwards in the area of each separating lacquer strip the semi-tubular

Die nach dem Verfahren hergestellte Tasche ist dadurch gekennzeichnet, dass die den. Taschenboden bildende Verbindung band- oder nahtförmig ausgebildet und gegen das Tascheninnere eine mit Abstand längs der zugeordneten Kante verlaufenden Linie bildet, dass die Taschenwände parallel zu dieser Verbindung gefalzt werden, wobei dieser Falz einen zweiten Tasclienboden bildet, dass zwischen dem gefalzten Teil der Taschenwände und der anliegenden Taschenwand, zwischen der Linie und der zugeordneten Kante, eine naht- oder bandförmige feste Verbindung besteht, die sich über die ganze Taschenwandbreite erstreckt und dass im gefalzten Teil, zwischen der Linie und der letztgenannten naht- oder bandförmigen Verbindung über die ganze Taschenwandbreite eine durchgehende Perforation vorgesehen ist.film parts through two parallel, across the half-tubular film extending connecting seams connected to one another and along a line lying between these connecting seams be cut through. The bag produced by the method is characterized in that the. Pocket bottom The connection forming a band or seam is formed and against the inside of the pocket one with a distance along the associated edge running line forms that the pocket walls are folded parallel to this connection, this fold a second Tasclienboden that forms between the folded part of the pocket walls and the adjacent pocket wall, between the line and the associated edge, a seam-shaped or band-shaped There is a fixed connection that extends over the entire width of the pocket wall extends and that in the folded part, between the line and the last-mentioned seam or band-shaped connection A continuous perforation is provided over the entire width of the pocket wall.
Vorzugsweise ist vorgesehen, dass die Folie eine thermoplastische Kunststoffolie ist, und dass die Verbindungsnähte Schweissnähte sind.It is preferably provided that the film is thermoplastic Is plastic film, and that the connecting seams are welded seams.
