EASY OPENING CAN CAP FOR NEGATIVE PRESSURE CAN

摘要

PROBLEM TO BE SOLVED: To manufacture a tab non-separation type easy opening can cap to be used for a negative pressure can, to be easily opened and not damaging an inner face film of the can cap even when the can caps are overlapped. SOLUTION: A first recess 6 and a second recess 11 deeper than the first recess 6 are formed on a panel section 2 of an easy opening can cap 1 for a negative pressure can, and an opening piece 8 parted by a score line 7 is formed on the first recess 6. A tab 13 is so fixed by a rivet 16 as to position a pressing-down front end 7 on the upper side of the opening piece 8 and a holding-up rear end 18 on the upper side of the second recess 11. Two recessed lines 19 extending in the direction of crossing orthogonally a straight line connecting the pressing-down front end 17 with the holding-up rear end 18 are formed at an interval on the tab 13.
