ABSTRACT:
An apparatus for the separable attachment of a lid (1') to a bottom part is described, both parts being connected to each other by a first welded seam (3), a first tear line (5) being provided which extends parallel with the first welded seam (3).
In order no longer to have to tear the lid upwards or even bend it and in order to be able to provide such a tearing-open device for a package, it is according to the invention proposed that at a distance (a) from the first tear line (5) and at least along a first portion (5) thereof, a second tear line (4) be so disposed to extend in the lid (1') that a tear-off strip (6) can be formed between the two tear lines (4, 5).
