Packaging Bag with Tearing Aid

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° and less than 90°.

1 . Packaging bag with tearing aid, comprising a front and a back, said front and back being connected to each other at least partially in their edge regions with a material fit thereby defining a joint edge of a given edge width, an opening notch formed in said joint edge, and two weakened lines which extend across the width of the packaging bag defining a tearing region on the front and the back and which divide the packaging bag into an upper bag part and a lower bag part, wherein an extension of a center line of said opening notch intersects said weakened lines at an intersection point at a distance from the tip of said notch outside of said notch forming a tear angle with said weakened lines of greater than 0° and less than 900. 
   
   
       2 . Packaging bag according to  claim 1 , wherein said front and said back have a rectangular form at least in said tearing region, and said opening notch is formed on one of the side edges, and wherein said center line of said opening notch extends perpendicular to a side edge, and wherein the direction of the line layout of said weakened lines at said intersection point encloses an angle greater than 0° and less than 90° with said side edge. 
   
   
       3 . Packaging bag according to  claim 2 , wherein the course of said weakened lines represents an angled straight line. 
   
   
       4 . Packaging bag according to  claim 2 , wherein the course of said weakened lines is a sinusoid. 
   
   
       5 . Packaging bag according to  claim 1 , wherein said front and said back have a rectangular form at least in said tearing region, wherein said opening notch is formed on one of the side edges of said bag, and wherein said center line of said opening notch extends at an angle greater than 0° and less than 90° relative to said side edge, the course of said weakened lines is a straight line. 
   
   
       6 . Packaging bag according to  claim 1 , wherein said front and said back have, at least in said tearing region, the shape of an isosceles triangle, and said opening notch is formed on one of said side edges of said bag, wherein said center line of said opening notch extends perpendicular to a side edge, and the direction of the course of said weakened lines at said intersection point encloses, with said side edge, an angle greater than 0° and less than 90°. 
   
   
       7 . Packaging bag according to  claim 1 , wherein said front and said back have the shape of an isosceles triangle, at least in said tearing region, and said opening notch is formed on one of the side edges of said bag, wherein said center line of said opening notch extends at an angle greater than 0° and less than 90° relative to said side edge, and the course of the weakened lines is a straight line. 
   
   
       8 . Packaging bag according to  claim 1 , wherein said opening notch is in the upper bag part. 
   
   
       9 . Packaging bag according to  claim 1 , wherein said intersection point lies within said joint edge. 
   
   
       10 . Packaging bag according to  claim 1 , wherein said tear angle is greater than 10° and less than 45°. 
   
   
       11 . Packaging bag according to  claim 1 , wherein said weakened line is a lased line.
