Abstract: A lid for a beverage can possessing excellent characteristics in pressure resistant strength in which a predetermined pressure requirement is ensured by a simple gauging down. An annular groove portion of the can lid is formed to have such cross-sectional shapes that a panel wall portion is connected to a chuck wall radius portion so that a tangential line at a second contact point is vertical with respect to an axial direction of a center panel portion, while a chuck wall portion is connected to the chuck wall radius portion so that a tangential line at a first contact point is inclined to the radially inner side, and a curved portion with a radius R1 is provided at a height h1 from the lowest point of the chuck wall radius portion and bent to the radially outer side.

Abstract: A lid for a beverage can excellent in pressure resistant strength in which a predetermined pressure requirement is ensured by a simple gauging down. An annular groove portion 10 of the can lid is formed to have such cross-sectional shapes that a panel wall portion 3 is connected to a chuck wall radius portion 4 so that a tangential line at a second contact point e2 is vertical with respect to an axial direction of a center panel portion 1, while a chuck wall portion 5 is connected to the chuck wall radius portion 4 so that a tangential line at a first contact point e1 is inclined (inclined by ?1 in the clockwise direction) to the radially inner side, and a curved portion (hereinafter referred to as “first radius portion 5a”) with a radius R1 is provided at a height h1 from the lowest point of the chuck wall radius portion 4 and bent to the radially outer side.

Abstract: An easily unsealable container closure having re-sealing performance and comprising a closure member having an opening portion that has been formed in advance, and an unsealing tab which is so fitted to the outer surface side of the closure member as to cover the opening portion and is hermetically adhered to the periphery of the opening portion, wherein the unsealing tab includes a flexible tab member and a plug member integrally adhered to the tab member and is so formed as to be fitted to the opening portion of the closure member, and the flexible tab member is hermetically fixed to the periphery of the opening portion in the closure member so as to be torn off. The container closure offers re-sealing performance which can be repetitively effected to temporarily seal again the once unsealed opening, and further offers excellent re-sealing performance, unseal indication function and easy-to-unseal performance.

Abstract: A necked-in and flange portion is formed in the open end of a seamless can body by using a can end holder driven for rotation about its axis, an axially movable inner roll of a reduced diameter disposed adjacent the can end holder, and a spinning roll positioned axially stationary outside the can body. While the can body with the open end telescoped onto the can end holder and in contact with the inner roll is rotated together with the can end holder, the spinning roll is advanced toward the can end holder and forced into the open end, and simultaneously the can body is moved in an axial direction away from the can end holder together with the inner roll, to form the necked-in and flange portion.
