摘要

A can (1) of the type having a cylindrical body on which is seamed a end (2) of the easy open type, said end (2) being fitted with a center panel (4) delimited by a scored ring (5), being said scored ring (5) laid out under and between the region delimited by a S-shaped bend (6) formed from said center panel (4) of end (2). The patent also foresees a process for the formation of said S-shaped bend (6) in which are performed the steps of: a) forming in basic end (2) a semi-toroidal protuberance (16) being the straight cross section of this protuberance (16) preferentially semi-circular; b) coining scored ring (5) as close as possible to external edge of toroidal protuberance (16); and c) deforming protuberance (16) through a radial compression and a compression transverse to same forming thus the S-shaped bend (6) with three thicknesses of material.
