Pack having tear-open aid

Abstract

The invention relates to a pack in the form of a stick or cushion, consisting of one or two sheets ( 7, 7′ ), which has at least one aluminum layer facing the contents and one layer, which faces away from the contents, is areally connected to the aluminum layer and is made of polyethylene terephthalate (PET layer) or other materials, having a tear-open aid in one of the outer surfaces, which comprises a weakening line in the PET layer. The invention is characterized in that the tear-open aid has at least two weakening lines ( 4, 5 ), the point of intersection of which in the outer surface lies at a distance from the nearest edge of the pack, and in that the angle between the weakening lines at the point of intersection is between 60° and 90° .

1 . A packet for packaging contents, the packet comprising:
 one or two sheets, each sheet having at least one aluminum layer facing the packet contents and at least one outer surface layer that faces away from the packet contents, where the outer surface layer is made of at least one material selected from the group consisting of polyethylene terephthalate (PET), paper, oriented polypropylene (OPP) and oriented polyamide (OPA), and where the additional layer is connected to an aluminum layer over substantially their entire areas;   wherein the packet has a tear-open aid in the outer surface layer, the tear-open aid including at least two intersecting weakening lines in the outer surface layer.   
     
     
         2 . The packet as claimed in  claim 1 , wherein the point of intersection of the at least two intersecting weakening lines in the outer surface layer is non-coincident with the nearest edge of the pack. 
     
     
         3 . The packet as claimed in  claim 1 , further comprising a second tear-open aid on an opposite outer surface of the packet, configured so that the two tear-open aids are substantially aligned with one another. 
     
     
         4 . The packet as claimed in  claim 1 , wherein at least one of the tear-open aids includes double or multiple parallel weakening lines. 
     
     
         5 . The packet as claimed in  claim 1 , wherein one of the weakening lines extends parallel to an adjacent edge of the packet. 
     
     
         6 . The packet as claimed in  claim 1 , wherein the point of intersection of the weakening lines is disposed in a corner region of the packet, and wherein one of the weakening lines extends toward the corner. 
     
     
         7 . The packet as claimed in  claim 6 , wherein the packet has a rectangular or square outline, and the point of intersection of the weakening lines lies on an angle bisector of the corner at a distance of 15 to 25 mm from the apex of the corner. 
     
     
         8 . The packet as claimed in  claim 5 , wherein the distance of the weakening line from the adjacent edge is between about 3 and about 20 mm. 
     
     
         9 . The packet as claimed in  claim 4 , wherein the spacing between adjacent double or multiple parallel weakening lines is less than about 1 mm. 
     
     
         10 . The packet as claimed in  claim 1 , wherein the packet has the form of a stick or cushion. 
     
     
         11 . The packet as claimed in  claim 2 , wherein the angle defined by the at least two intersecting weakening lines is between 60° and 90° . 
     
     
         12 . The packet as claimed in  claim 5 , wherein the distance of the weakening line from the adjacent edge is between about 10 and about 15 mm. 
     
     
         13 . The packet as claimed in  claim 4 , wherein the spacing between adjacent double or multiple parallel weakening lines is less than about 0.5 mm. 
     
     
         14 . The packet as claimed in  claim 4 , wherein the spacing between adjacent double or multiple parallel weakening lines is less than about 0.1 mm.
