<P>PROBLEM TO BE SOLVED: To provide a can lid or the like suppressing deterioration in operability of a tab which may be caused when a beverage can is made smaller in size or an opening is made larger in size. <P>SOLUTION: In order to form the opening on a panel, a fourth piece part 540 shown in (A) is pulled upward and pressed in a right direction in the figure. Thus, a third piece part 530 moves in the right direction in the figure, and also a second piece part 520 rotates about a lower end in the figure. Thus, a tab 500 is deformed as shown in (A) to (F). Thereafter, an upper surface of the tab 500 is pressed by a user, and the third piece part 530 and the fourth piece part 540 are located nearer to the side of a first piece part 510 and the second piece part 520 than a virtual line L1 as shown in (G). Thereafter, the second piece part 520 shown in (G) is pressed by the user from below. Thus, a left end in the figure of the first piece part 510 presses the panel, and then the opening is formed on the panel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
