摘要： An easily openable metallic can lid and a method of manufacturing the same, in which a guide groove in the can lid for opening is S-shaped in cross section to improve an opening property, generation of resin film defects in molding process is eliminated, and repair coating on inner and outer surfaces of the can lid is unnecessary. When an opening piece, which is easily opened by a hand of a user, is formed on the metallic can lid, a property of a resin film on a metallic sheet, shapes, dimensions and clearance of shoulders on a punch and a die, a retained thickness of a guide groove for opening, a degree of press-back work and the like are specified to form a guide groove for opening, which is S-shaped in cross section, without breaking the resin film, thereby attaining a superior opening property.
