EASY-OPENING CAN LID AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an easy-opening can lid in which an opening force can be stabilized at a central pushing end. SOLUTION: This easy-opening can lid 10 comprises a flange arranged at an outer circumference for engaging with an opening edge of a container; a central plate segment enclosed by the flange with its central segment being protruded to be tapered off at its end from the flange toward an outer side of the can lid; an expected opening segment 30 arranged at a substantial extremity end of the central plate segment; a breakage line 28 formed around the expected opening segment 30 while leaving a part thereof; and a sealing segment 32 arranged to cover the inner side surface at the central plate segment. A thickness of the sealing segment 32 is uniform in a circumferential direction of the expected opening-segment 30 and has a desired thickness.
