PURPOSE: To provide an end structure capable of being easily opened by using thinner metals while keeping the safety in a venting action necessary for a carbonated beverage can, by mounting a venting bead on an easy-open container end by coining. CONSTITUTION: A short coined depression or bead 40 in a tear panel is formed in the public side preferably close to a score line 15 at the end of a vent region 35 opposite from an inner hook 16 located at the radially inward end of the tear panel score line. Whereby the compression force is acted, and a part of the metal of the tear panel is placed in a region where a score stopper is placed. During the initial opening or venting action, as a rivet 25 is lifted by initial tab motion, separation proceeds along the score line beneath a nose of the tab.
