Problems solved by technology

To this end, it is necessary to have a mechanism for detecting the position of the weakening line, in order to control the signal that can be issued thereby, as a control variable for realizing the position positioning between the packaging bag and the processing tool for opening the gap, which is very cumbersome

Embodiment Construction

[0035] The packaging bag according to the invention, like the packaging bags known from practice, has a front side 1 and a back side 2 which are at least partially welded or glued together in the edge region. These edge regions glued or welded to one another form a joint edge 3 of a predetermined edge width.

[0036] FIG. 1 a shows a top view of a first embodiment of the packaging bag according to the invention on the front side 1 . The front side 1 and the back side 2 located behind it have a rectangular shape and are connected to each other by an annular joint edge 3 .

[0037] The blank 4 for the packaging bag shown in FIG. 1 b is preferably cut to length from a web of packaging material and has twice the width of the packaging bag. The front side 1 and the back side 2 overlap each other coveringly by folding along the middle line. The crease created by folding forms one of the two sides. It is sufficient to join both the other side and the lower edge to provide a refill...

Abstract

The invention relates to a packaging bag with a tearing aid, with which it is reliably provided that the packaging bag is opened in a defined way by manual tearing by the user, so that no packaging contents are lost. The packaging bag is essentially made from a front and a back, which are connected to each other in their edge regions with a material fit and which thus forms a joint edge, in which an opening notch is formed, whose center line intersects two weakened lines at an intersection point starting at a distance from the notch tip. These weakened lines each extend across the width of the front and the back. The direction of the weakened line at the intersection point encloses, with the center line, a tear angle greater than 0 DEG and less than 90 DEG .

Description

technical field [0001] The present invention relates to a packaging bag made of flexible single-layer or multi-layer packaging material, such as paper, plastic and / or metal, with tearing aids that make it possible to achieve the specified properties of the packaging bag. torn apart. Background technique [0002] The necessity of a defined tearing of the packaging bag is particularly important when the packaged goods are, for example, liquids, granular materials or a large number of small particles, so that the packaged goods may partly or even completely leak out during an uncontrolled opening of the packaging bag, And people start from this, promptly the consumer does not need tool, but is torn by hand to realize opening. [0003] The packaging size and packaging materials of the same type of packaging bags are determined according to the type and quantity of packaging items, and can be very different. Although these packaging bags differ in shape, in the broadest sense t...
