发明名称	Container part which can be torn open
摘要	The container part (10) is provided with a pair of scored lines (16) which laterally bound a tear-off strip (18). A tab (20), produced as a separate sheet-metal part, is moulded onto the tear-off strip (18) in a welding zone (42) at one of its ends. A scored starting line (30) extends over the tear-off strip (18) between the welding zone (42) and the free end (32) of the tab (20). The scored start line (30) extends only in a central region of the tear-off strip (18) essentially transversely to the lateral scored lines (16) and runs near to the two lateral scored lines (16) away from the free end (32) of the tab (20). Near to each of the two lateral scored lines (16), the welding zone (42) covers the scored start line (30). It is thus ensured, essentially irrespective of manufacturing inaccuracies, that a tearing-off operation can be reliably introduced by rolling up the tab. <IMAGE>
