Description

Kunststoffbeutel-Die Erfindung bezieht sich auf einen Kunststoffbeutel, dessen Boden durch mehrere hintereinanderliegende, bis zu den beiden Seitenkanten reichende Schweißnähte gebildet ist.Plastic bag-The invention relates to a plastic bag, its bottom by several one behind the other, up to the two side edges reaching welds is formed.

Wenn bei einem solchen Kunststoffbeutel, in dem flüssiges Füllgut enthalten ist, die innere Schweißnaht undicht wird, verteilt sich das durch die Undichtigkeit gelangende Füllgut in dem zwischen der inneren und äußeren Schweißnaht liegenden Raum, und es besteht die Gefahr, daß die Undichtigkeit zunächst nicht wahrgenommen wird. If in such a plastic bag, in the liquid contents is contained, the inner weld seam is leaking, it is distributed through the Leaking filling material in the between the inner and outer weld seam lying space, and there is a risk that the leak will not initially is perceived.

Dies soll durch die Erfindung verhindert werden. This is to be prevented by the invention.

Gemäß der Erfindung sind an der Bodenseite zusätzlich zu der unteren Schweißnaht winkelige oder gebogene, z. B. wellenförmige Schweißnähte angeordnet.According to the invention are on the bottom side in addition to the lower Weld angled or curved, z. B. wave-shaped welds arranged.

Beim Auftreten einer Undichtigkeit an der inneren Schweißnaht sammelt sich das durch diese hindurchgetretene Füllgut an den tiefsten Stellen der durch die winkeligen oder gebogenen Schweißnähte gebildeten Sicherungskammern. Dadurch wird es möglich, die Undichtigkeit schon frühzeitig genug zu erkennen, um infolge dieser Warnung schon bei geringstem Verlust des Füllgutes den fehlerhaften Beutel auswechseln zu können.When a leak occurs at the inner weld seam collects the product that has passed through this is at the deepest points of the fuse chambers formed by the angular or curved weld seams. Through this it will be possible to detect the leak early enough to be able to as a result With this warning, the faulty bag is detected even if the product is lost even at the slightest loss to be able to replace.

In den Zeichnungen sind einige Ausführungsbeispiele der Erfindung schematisch dargestellt und nachstehend beschrieben. In the drawings are some embodiments of the invention shown schematically and described below.

F i g. 1 zeigt einen Beutel mit zusätzlichen zwei winkeligen Schweißnähten, Fig.2 mit zusätzlichen zwei gebogenen Schweißnähten, F i g. 3 mit zusätzlichen drei wellenförmigen Schweißnähten. F i g. 1 shows a bag with additional two angled weld seams, Fig. 2 with additional two curved welds, F i g. 3 with an additional three wavy welds.

Der oben offene Kunststoffbeutell ist zusätzlich zu der unteren Schweißnaht 2 bei der in F i g. 1 dargestellten Anordnung mit zwei übereinanderliegenden winkelförmigen Schweißnähten 3 und 4 versehen. Bei undichter Schweißnaht 3 sammelt sich das hindurchgetretene Füllgut an der tiefsten Stelle 5 der Sicherungskammer 6. The plastic bag, open at the top, is in addition to the lower weld seam 2 at the in F i g. 1 shown arrangement with two superimposed angular Weld seams 3 and 4 provided. In the event of a leaky weld seam 3, what has passed through collects Filling material at the lowest point 5 of the safety chamber 6.

Wird bei der Anordnung der Fig.2 die innere bogenförmige Schweißnaht 7 undicht, so erscheint das hindurchgetretene Füllgut an der tiefsten Stelle 8 der Sicherungskammer 9, die mit der bogenförmigen Schweißnaht 10 gebildet wird. In the arrangement of FIG. 2, the inner arcuate weld seam 7 leaking, the product that has passed through appears at the lowest point 8 of the Fuse chamber 9, which is formed with the arcuate weld seam 10.

In F i g. 3 sind drei wellenförmige Schweißnähte 11, 12 und 13 dargestellt, bei denen zwei Sicherungskammernl4 und 15 gebildet werden, an deren tiefsten Stellen 16 und 17 sich durchgetretenes Füllgut zu sammeln vermag. In Fig. 3 three wave-shaped welds 11, 12 and 13 are shown, in which two fuse chambers 4 and 15 are formed, at their lowest points 16 and 17 is able to collect the product that has passed through.
