Claims

[Scope of utility model registration request]

(1) In order to tear the opening piece demarcated by the score line on the top plate of the lid body from the top plate of the lid body, a rivet or the like is attached to a part of the opening piece at a position relatively close to the outside of the top plate. In a liquid can with an opening tension piece attached, the score line is
at least a portion of a first score in a spiral shape that passes through an initial breakage position spaced apart from the stud toward the center of the lid body and a position close to the outside of the top plate of the lid body from the stud, and gradually becomes further away from the stud;
Two enlarged scores extending from both the initial breakage position and one end of the first score on the side of the rivet toward the outside of the control top plate beyond the center of the lid body, with an appropriate distance between the two ends thereof. An easy-to-seal can lid characterized by a structure in which lines are engraved.

(2) In a liquid can, in which an opening piece defined by a score line provided on the top plate of the lid body is opened by pulling up an opening tension piece fixed with a rivet at a position relatively close to the outside of the top plate, The ends of the two score lines are formed at a position close to the outside of the top plate of the lid body with an appropriate distance from each other, and the initial breakage position of the score line or its vicinity is closer to the center of the lid than the tip of the fulcrum leg of the tension piece. The score line is located in the direction of the container, and the outer position where the score line is subsequently broken at or near the initial breakage position is on the outer side of the lid top plate than the rivet, and the score line that terminates on the outside of the lid top plate is - At least one of the fulcrum leg tips extending substantially completely across the lid body and along its diametrical direction 7 and serving as a fulcrum when the opening piece is initially opened is substantially cut outside the opening piece, that is, at the time of opening. 2. The easy-open can lid according to claim 1, characterized by a structure located outside the torn portion.

(3) In order to tear the opening piece marked by a score line on the lid top plate from the lid top plate, an opening tension piece is attached to a part of the opening piece with rivets or the like. 2. The easily-sealable can lid according to claim 1, wherein the rivet for fixing the fixing portion of the opening tension piece is provided closer to the center of the lid body than the tip of the fulcrum leg of the tension piece.
