Patent attributes
A can lid is provided for excellence in an explosion-proof function and a suitability for a hammering inspection. A buckling-inducing section that is easily deformed angularly is formed on a plurality of sites in a circumferential portion of a panel section. A score line intersects with a virtual line passing through a center of the panel section and a center of the buckling-inducing section. End portions of the score line are situated closer to the center of the panel section than a virtual boundary line extending perpendicular to the virtual line. A circular depression is formed at the center of the panel section. A slant wall section is formed between the buckling-inducing section and an inner side wall, and the slant wall section is joined to the inner side wall through a curved portion.
