METHOD FOR MAKING EASY-OPEN LIDS WITH IMPROVED SCORING
摘要
The easily opened metal lid (1) has a central panel (3) and a crimped edge (4) and an incision (2) on an incision band (6) forming the dished bottom (20). A ring with a prong (9) allows perforating the incision and the opening. The incision band makes an angle beta which is not equal to zero with the mean plane (17) of the central panel. The incision band is situated on the periphery of the central panel and the internal skirt (5) of the crimped edge and forms a plane inclined between the panel and the skirt.
