摘要： A metal easy open can lid, and a process for producing the same, wherein the can openability is improved and the occurrence of defects in the resin film at the time of shaping is eliminated whereby repair coating of the inner and outer surfaces are made unnecessary by making the cross-sectional shape of the opening guide groove of the easy open can lid an S-shape are provided, wherein, when forming the opening piece for easy manual opening in the metal lid, the properties of the resin film on the metal sheet, the shape and dimensions of the shoulder portions of the punch and die, the clearance, the residual thickness of the opening guide groove, the degree of the push-back processing, etc. are specified so as to achieve a superior can openability without breakage of the resin film by forming an opening guide groove with an S-shaped cross-section.
