摘要： PROBLEM TO BE SOLVED: To stably reduce a can opening force by a method wherein a distance from the location of a tab fixing center and a finger-engaging gripping part, and an angle of the central line before turning are kept in specified ranges, and at the same time, a groove for opening having a bottom cross sectional shape of a specified radius of curvature, and a thinnest part of a specified thickness, is formed. SOLUTION: The central location of a tab fixing 2 is formed in a manner to be shifted by a distance (a) which satisfies (D-d)/2 L>d/2-a, and the tab 3 is rotated around the tab fixing 2 at an angle θ which satisfies -1 -(L+a)}. In addition, on the surface la of the can lid 1, a groove 6 for opening wherein the radius R is 0.01-1.0 mm, the thickness ts of a thinnest part 6a is in a range of 0.025-0.120 mm, and the bottom cross section is a curved surface shape, is formed.

摘要： PROBLEM TO BE SOLVED: To prevent the plated layer and the resin coated layer from being damaged, and eliminate a mending coating by a method wherein a groove for opening is formed on the face surface and the rear surface of a lid in such a manner that the bottom cross sectional shape may have a radius of curvature in a specified range, and the thickness of a thinnest part may stay in a specified range. SOLUTION: On a surface 1a of a can lid 1 having a resin coated layer 8 on both surfaces, a groove 2 for opening wherein a radius R has a curved surface shaped cross section of 0.1-1.0 mm, is formed. By this method, the groove 2 for opening can be formed while keeping a breaking location of the opening stable, without damaging the resin coated layer 8. Also, the thickness ts of a thinnest part 2a of the groove 2 for opening is made to stay in a range of 0.025-0.080 mm. Thus, while children or elderly people can easily open the can, when the can body receives an impact from the outside, a danger wherein the opening part is broken can be reduced.

摘要： PROBLEM TO BE SOLVED: To prevent damages from occurring to a gilt layer and resin-coated layers while stably reducing force required for opening of a can by a method wherein a first stage opening groove and a second stage opening groove each having specified front-end radius and groove width are formed in continuity. SOLUTION: Opening grooves 2 are formed respectively on the surface 1a and the reverse side 1b of a can lid 1 made of surface-treated steel plate with resin-coated layers formed on both sides thereof. The opening groove 2 is a two-stage groove that is formed in continuity of the first stage opening groove 2a and the second stage opening groove 2b. The depth D1 and the front-end radius ρ1 of the first stage opening groove 2a, the depth D2 and the front-end radius ρ2 of the second stage opening groove 2b and the thickness t of the can lid 1 shall be such that satisfies the relations represented by formulae I, II, III and IV. Therefor, corrosion resistance can be ensured without damaging resin coating while reducing force required for opening the can.
