摘要:
A rupturable can member (10) of sheet metal has a pair of scorings (16) which define a tearing strip (18) laterally. Welded onto the tearing strip (18) is a tongue (20) which has a thickened portion (24) at its welded-on end (22). This thickened portion is formed by a margin folded back towards the other free end (26) of the tongue (20).
