Abstract (en)
By conducting a strict study on a plate thickness, a pressure resistance is improved while satisfying the demand for further reduction of the plate thickness.A can lid has a center panel part, a panel wall part, a chuck wall radius part, a chuck wall part, and a curl part. t2 > t1 holds, where t1 represents a plate thickness of the center panel part, and t2 represents a plate thickness of a bottom end of the panel wall part.
