WIPO Patent Application WO/2016/170883
Kind Code:
A1
Abstract:
Provided are a can lid and can body which can form an opening without always using a tab. When a pressure-receiving section (280) is pressed and the pressure-receiving section (280) is displaced towards a second surface (222), an inclining portion (4A) of a base plate (210) that is located between a bead (231) and a weak section (270) inclines. A score line (220) is formed on the inclining portion (4A) so as to cut across the inclining portion (4A). As a result, when the pressure-receiving section (280) is pressed, a rupture of the base plate (210) occurs in the inclining portion (4A).
