摘要： An easy open can lid having: a panel portion, which is formed of an approximate disc shape, and in which a flange portion for fixing a can trunk is formed integrally on an outer circumference; a score line, which is formed near the periphery of the panel portion along the outer circumference of the panel portion; an opening piece, which is defined by the score line; and an opening tab, which is fixed near the periphery of the opening piece. This easy open can lid of the invention is characterized in that the score line is formed of an arcuate along periphery of the panel portion and both ends thereof are separated, and comprises a connecting portion connecting the opening piece with the panel portion, which is formed between the both ends of the score line, and a strength incrementing portion, in which a rupture strength thereof increases gradually toward the end portion of the score line.
