PURPOSE:To prevent the periphery of the worktop of a cap body from adsorbing an odor in the air and prevent the reinforcement of the edge of the worktop and overcap stack from being damaged, by injecting polythylene towards a laminated plate, thereby forming the overcap for a can used for dried milk, etc. CONSTITUTION:A cap body (a) is formed by injecting thermoplastic resin into a metal mold, towards a laminated plate (b), such as a label, in which a layer of thermoplastic resin is formed at least on one side of a paper plate having a plurality of holes 3 made through it along its edge with a specific interval. Also, a reinforcement and stack-rib 5 is formed on the surface of the laminated plate (b) of the cap body (a) by the thermoplastic resin which has passed through the plurality of holes 3 positioned with spaces between them. |
