ABSTRACT:
The invention concerns a cover strip for the pouring opening of a packing container. The strip is provided with a weakening line for ease in tearing off the cover strip. The bottom part of the cover strip is attached to a wall of the container so that it remains on the container after the cover strip per se is torn off.
