Claims

[Claim for Utility Model Registration] A score line for loop-shaped openings is carved on the end plate to demarcate the area of the opening piece to be removed, and a pulling tab is attached to one end of the area of the opening piece via a rivet. In a lid of a can body which is movably attached, a height is provided within the opening piece area on a tangent to the outer periphery of the rivet on the opposite side of the initial opening and perpendicular to the pulling direction of the lifting tab. Provide a rigid part,
On the other hand, the width between the opening score lines that intersect with the tangent line is set to be approximately twice the shaft diameter of the rivet, and the distance between the rivet center and an imaginary line that is parallel to the tangent line and passes through the center of the high-rigidity part. , where L is the radius of the rivet and t is the thickness of the rivet, is set in the range L-2t<<L-2t.
