ABSTRACT:
The can member (10) is provided with a pair of scorings (16) which define a tear-off strip (18) laterally. A tongue (20) produced as a separate sheet-metal part is welded onto the tear-off strip (18) in a welding zone (42) at one of its ends. Between the welding zone (42) and the free end (32) of the tongue (20), a starting scoring (30) extends over the tear-off strip (18) to within the vicinity of the two lateral scorings (16). The starting scoring (30) is part of a field (28) of a plurality of scorings formed on the tear-off strip (18) below the tongue (20). The welding zone (42) partially covers over this field (28). As a result, care is taken to ensure that a tearing open operation can be reliably initiated by rolling up the tongue, substantially regardless of inaccuracies in manufacture.
