Abstract

A can body made of a sheet metal blank has a tear strip extending between opposite ends of the blank and into a tongue extending from one blank edge. An overlapping portion at overlapping ends of the blank is completely welded, and the tongue width is greater than the strip width to assure tendency of rupture of the can body from opposite side edges of the tongue toward the strip to avoid premature breaking of the strip.
