Tear-open pouch

Abstract

The invention relates to a tear-open pouch ( 110 ) comprising a front face of the tear-open pouch ( 126 ) defined by an outer edge and a rear face of the tear-open pouch defined by an outer edge, the outer edges thereof being joined together in at least one join outer edge region of the tear-open pouch ( 110 ), a starting point for a predetermined tear-line (R 1 , R 2 ) being provided in such a join outer edge region. The front face of the tear-open pouch ( 126 ) and the rear face of the tear-open pouch are also joined together at least in portions in an inner region surface portion ( 130 ) arranged spaced apart from the outer edges thereof. The inner region surface portion ( 130 ) defines a predetermined tear-line deflection point, in which the tear-line (R 1 , R 2 ) is deflected, in order to terminate in a tear-line end point provided in a join outer edge region of the tear-open pouch ( 110 ), the tear-line (R 1 , R 2 ) extending between the tear-line starting point and the inner region surface portion ( 130 ) or/and between the inner region surface portion ( 130 ) and the tear-line end point through surface portions of the tear-open pouch ( 110 ) which are not joined together.
