Tear-open seal packaging

Abstract

The invention relates to a tear-open seal packaging ( 10 ), with a packaging element ( 12 ) having an opening ( 30 ) and a tear-open film ( 14 ), which closes opening ( 30 ) and is connected along its outer edge portion ( 16 ) with the opening edge ( 32 ) of packaging element ( 12 ) by a sealing seam ( 18 ). Sealing seam ( 18 ) has at least one indentation ( 26,28 ) which extends inwards from the outer edge of sealing seam ( 18 ), and whose depth of extension is less than width (B) of sealing seam ( 18 ) at the point of the indentation ( 26,28 ).

1 . Tear-open seal packaging, comprising a packaging element having an opening and a tear-open film, which closes said opening and is connected along an outer edge portion thereof with an opening edge of said packaging element by a sealing seam, said sealing seam having at least one indentation which extends inwards from an outer edge of the sealing seam, and the at least one indentation having a depth of extension which is less than the width of the sealing seam at the point of the indentation. 
     
     
         2 . Seal packaging according to  claim 1 , wherein at least one said indentation is disposed on an approximately arc-shaped section of the sealing seam. 
     
     
         3 . Seal packaging of  claim 1 , wherein at least one said indentation is disposed in a region between an imaginary tangent of the outer edge of the sealing seam and an imaginary parallel tangent of an inner edge of the sealing seam. 
     
     
         4 . Seal packaging according to  claim 1 , wherein at least one said indentation is shaped like a recess with an arc-shaped edge. 
     
     
         5 . Seal packaging according to  claim 1 , wherein the tear-open film is provided with a free tear-open tab at one edge portion on one indentation in the sealing seam. 
     
     
         6 . Seal packaging according to  claim 1 , wherein at least two said indentations are contrived in the sealing seam, and are located at a distance from each other along the sealing seam. 
     
     
         7 . Seal packaging according to  claim 6 , wherein the tear-open film is provided with a free tear-open tab at one edge portion on one indentation in the sealing seam and the free tear-open tab is disposed between two indentations in the sealing seam. 
     
     
         8 . Seal packaging according to  claim 1 , wherein the indentations are disposed at opposite points in the sealing seam. 
     
     
         9 . Seal packaging according to  claim 1 , wherein the packaging element is an intermediate ring which forms a top edge of a container and is connected to another part of the container.
