ABSTRACT:
A container (1) is provided with a cover (2) which has a guarantee strip (4) which can be divided along a design tearing line. In this arrangement, the guarantee strip (4) engages under a holding bead (9) and at the same time is protected from unauthorized manipulation of the guarantee strip, by a protective bead (10). So that the container which is produced by an injection moulding process can be produced by means of axially openable moulding tools, the holding bead and the protective bead are interrupted in such a way, and are arranged offset relative to each other in gaps, in such a way, that the respective holding bead (9) only extends, on the outside wall of the container, over the length over which the protective bead (10) is interrupted. In this way there is no undercut configuration at any point, which would prevent axial retraction of the moulding tools or axial ejection of the container.
