Description
Die Erfindung betrifft einen Blockbodenbeutel bestehend aus einer Vorderwand und einer Rückwand die an ihren Längsseiten miteinander verschweißt sind, einem Boden, der im zusammengefalteten Zustand des Beutels eine Bodenfalte bildet, die sich über die gesamte Breite des Bodens erstreckt und in das Beutelinnere hineinragt, wobei die beiden zur Bildung der Bodenfalte eingefalteten Seitenwandabschnitte voneinander durch eine innere Falzlinie und von der jeweiligen Seitenwand durch eine zur inneren Falzlinie parallele äußere Falzlinie angeteilt sind und der Beutel zur Bildung des Blockbodens zu den Falzlinien schräg verlaufende Abschweißungen aufweist, die sich von den äußeren Falzlinien zu den Längsseiten erstrecken.The The invention relates to a block bottom bag consisting of a front wall and a back wall the on their long sides welded together are, a bottom that is in the folded state of the bag forming a bottom fold that extends across the entire width of the Bodens extends and projects into the bag interior, the two to Forming the bottom fold folded sidewall sections from each other through an inner fold line and from the respective side wall through a parallel to the inner fold line outer fold line are divided and the bag for forming the block bottom obliquely to the fold lines Abschweißungen which extends from the outer fold lines to the long sides extend.
Ein Blockbodenbeutel wird vorzugsweise dort eingesetzt, wo Waren, wie beispielsweise Brote, verpackt werden. Bevorzugt werden Blockbodenbeutel die auch Klotzbodenbeutel genannt werden, aus thermoplastischen Kunststofffolien gefertigt. Vorstellbar ist hierbei die Fertigung aus einer transparenten und/oder eingefärbten und/oder metallisierten thermoplastischen Kunststofffolie. Gefertigt wird ein derartiger Beutel zumeist aus einer gefalteten Kunststofffolienbahn, wobei die einzelnen Beutel mittels eines Trennschweißens voneinander getrennt werden. Zur Bildung des Blockbodens wird die gefaltete Kunststofffolienbahn an ihrem geschlossenen Ende zur Bildung einer Bodenfalte eingefaltet. Nach dem Einfalten wird dann im eingefalteten Bereich die untere rechte und linke Ecke im Bereich der Bodenfalte verschweißt, so dass sich nach dem Verschweißen der Längsseiten der sich aus der Bodenfalte ergebene Blockboden gebildet ist.One Block bottom bag is preferably used where goods, such as For example, breads, to be packed. Preference is given to block bottom bags which are also called block bottom bags, made of thermoplastic Made of plastic films. It is conceivable here the production from a transparent and / or colored and / or metallized thermoplastic plastic film. Is made such a Bag mostly made of a folded plastic film, wherein the individual bags are separated by means of a Trennschweißens. to Formation of the block bottom becomes the folded plastic film web folded at its closed end to form a bottom fold. After folding is then in the folded area, the lower right and left corner welded in the area of the bottom fold, so that after welding the long sides which is formed from the bottom fold resulting block bottom.

Aufgabe der vorliegenden Erfindung ist es, einen Blockbodenbeutel bereit zu stellen, der die Nachteile aus dem Stand der Technik überwindet und eine hohe Dichtheit während des Einfüllens und des Transportes, sowie der Lagerung gewährleistet und der darüber hinaus kostengünstig zu fertigen und konstruktiv einfach aufgebaut ist.task The present invention is to provide a block bottom bag to provide, which overcomes the disadvantages of the prior art and a high tightness during of filling and transport, as well as storage and beyond economical to manufacture and structurally simple.
Die Lösung der gestellten Aufgabe wird erfindungsgemäß dadurch bereitgestellt, dass sich die Abschweißungen zumindest bereichsweise parallel zu den Längsseiten des Blockbodenbeutels erstrecken. Durch die erfindungsgemäße Ausbildung der Abschweißungen im Bereich der Bodenfalte, ist nun die Möglich keit geschaffen eine hohe Dichtheit während der am stärksten den Beutel belastenden Phasen zu gewährleisten. Dabei ist der Beutel lediglich durch den Umbau der Schweißwerkzeuge kostengünstig und mit minimalem konstruktiven Aufwand herzustellen. Durch die zu den Längsseiten parallelen Verschweißungen, kommt es zu einer sehr viel stabileren Ausbildung des Blockbodenbeutels im Bereich des Blockbodens, wodurch eine hohe Dichtheit während der Verwendung des Beutels gewährleistet wird. Insbesondere in dem Übergang vom 4-lagigen in den 2-lagigen Bereich ist die statische Belastung am stärksten und führt an diesen Stellen sehr schnell zu einem Einriss beziehungsweise es kommt zu einer Lochbildung. Durch die Ausbildung der bereichsweise parallel zu den Längsseiten verlaufenden Abschweißungen wird die Kraft auf den Übergangsbereich vom 4-lagigen zum 2-lagigen sehr viel besser verteilt, wodurch sehr viel stabilere Blockbodenbeutel herstellbar sind.The solution The object is achieved according to the invention provides that itself the Abschweißungen at least in regions parallel to the longitudinal sides of the block bottom bag extend. The inventive design of the Abschweißungen in Area of the bottom fold, is now created the possibility of a high Tightness during the strongest to ensure the bag incriminating phases. Here is the bag only by the conversion of welding tools cost and produce with minimal design effort. By the to the long sides parallel welds, There is a much more stable formation of the block bottom bag in the area of the block bottom, whereby a high tightness during the Use of the bag is guaranteed. Especially in the transition from the 4-ply to the 2-ply area, the static load is on most and leads at these points very quickly to a tear, respectively it comes to a hole formation. Through the training of the area parallel to the long sides extending Abschweißungen the force is on the transition area from 4-ply to 2-ply distributed much better, which makes much more stable Block bottom bags are manufacturable.
