Abstract (en)
[origin: EP0221447A2] The sheet-metal blank has a tear-off strip (2) running between predetermined breaking lines (3, 4). At the end of the tear-off strip (2) opposite the tongue (5) of the same, a scratch (6) running transversely between the scribed predetermined breaking lines (3, 4) is provided in direct proximity to the corresponding edge (7) of the blank. Consequently, upon welding together, a starting opening is formed which enables the homogeneous weld to be broken without problem. <IMAGE>
