<P>PROBLEM TO BE SOLVED: To provide a can lid or the like for preventing the operating load of a tab from increasing when a region surrounded by a score line is large or the tab is small. <P>SOLUTION: A first score line 430 is formed on the surface of a panel 400. The first score line 430 is formed so as to surround a region RA pressed by the tab, in the panel 400. The first score line 430 is also formed in an approximately U shape so as to bulge toward the outer peripheral edge 410 of the panel 400. A second score line 450 is formed in a region surrounded by the first score line 430 on the surface of the panel 400. The second score line 450 has one end 451 and the other end 452. The one end 451 of the second score line 450 is positioned inside the region surrounded by the first score line 430 and the other end 452 is connected to the first score line 430. <P>COPYRIGHT: (C)2012,JPO&INPIT |
