摘要： 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.

摘要： Described is an apparatus (1) for bending a cap equipped with a security seal and a closure casing defining a perimeter edge housing the security seal on a perimeter edge, comprising a support unit (2), including a seat (201) for receiving a closure casing, and a locking unit(3); the support unit (2) and the locking unit (3) are oriented along a longitudinal axis (X) and movable relative to each other along the longitudinal axis (X) between a spaced-apart position and a close-together position wherein the locking unit (3) engages the closure casing positioned in the seat (201) of the support unit. A deforming element (303) is positioned laterally to f the longitudinal axis (X) and is movable, away from and towards the longitudinal axis (X), between an inactive position and an active position, wherein it presses outside the perimeter edge of the closure casing to deform it plastically towards the longitudinal axis (X); the deforming element (303) is also movable by rotating about the longitudinal axis (X).

摘要： In a case where an indication is provided between a fixed part and a pulling-up part of a tab, the tab is provided with necessary rigidity and disturbance of the indication is suppressed. A tab for opening a can lid includes a pulling-up part provided on one end side in a longitudinal direction of the tab, a pressing-down part provided on another end side in the longitudinal direction, a fixed part provided between the pulling-up part and the pressing-down part and formed by being demarcated by a U-shaped slot and fixed to a can lid body, and a curl part formed continuously at a peripheral edge excluding a connected-piece-cutting trace provided at the pressing-down part, a surface between the fixed part and the pulling-up part is a display surface, and a back surface side of the display surface is an abutted surface against which a shaping tool is abutted.
