Abstract
An improved opener for a packaging container arranged to form an opening in one wall to remove the contents includes a tear-open portion surrounded by a weakening line and a pull tab connected to the tear-open portion. To enable use of the pull tab as a reclosure element, it has a stopper-like lower extension which has a complemental outline to that of the tear-open portion and on which a shear edge is disposed. The pull tab is firmly connected to the tear-open portion with a narrow strip of a fusing glue.
