摘要：
A method for manufacturing a cover for a can-like container providing improved peelability of a handle. The cover (3) is made by forming a second resin layer (58, 59) by injection molding on a multi-layer sheet (64) which oxygen, water, and the like cannot permeate. A thermally weldable first resin layer (66) is provided on the upper surface of the multi-layer sheet (64). The handle is formed by the second resin layer. A treatment is carried out for allowing the handle to be easily peeled off the multi-layer sheet to all or part of a region of the multi-layer sheet in contact with the underside of the handle.
