Package made of flexible material with tearing opening

Abstract

A package for granular, pasty or liquid products, provided with a tearing opening, wherein at the tearing opening, on the inside of the package, there is applied a strip ( 3 ) pre-cut in two slices ( 4, 5 ) by a separation line ( 6 ) which extends parallel to the upper edge ( 2 ) of the package, so that during tearing the tear proceeds straight along the separation line ( 6 ).

1 - 10 . (canceled) 
     
     
         11 . A package made of flexible material upside closed by means of a weld (SP) at or close to the upper edge ( 2 ) thereof and provided with a tearing opening below said weld (SP), characterized in that, at said tearing opening below said weld (SP) and inside the package, a strip ( 3 ) made of a sheet material is applied, which is pre-cut in two halves or slices ( 4 ), ( 5 ) along a separation line ( 6 ) running parallel to said upper edge ( 2 ) of the package, such that during the tear-off operation the tearing proceeds along said separation line ( 6 ). 
     
     
         12 . The package according to  claim 11 , wherein said pre-cut strip ( 3 ) is applied within opposite walls of the package ( 10 ).
