Conical packaging having improved tearable opening

Abstract

The present invention relates to a conical packaging, in particular a pointed conical packaging ( 10 ), preferably for food, such as ice cream in wafers and the like, comprising a packaging wall that tapers conically starting from a removal end ( 10 a ) along a packaging axis (V), wherein the packaging wall has a tearing aid ( 16, 18 ) having a first material weakening ( 16 ) of the packaging wall material and having a second material weakening ( 18 ) extending at a distance to the first material weakening ( 16 ) in such a way that the first ( 16 ) and the second material weakening ( 18 ) define a tearable strip ( 14 ) therebetween, wherein the tearable strip ( 14 ) extends in the direction of the packaging axis (V) starting from the removal end ( 10 a ) of the packaging ( 10 ) with a tearable component and ends in a axially central area (A) of the packaging ( 10 ).
