Abstract
An easily openable container lid has a shell and a liner embossed on the inner surface of a top panel wall and a pair of scores formed in the shell. The liner is adhered over the entire surface thereof to the inner surface of the top panel wall. At least second portions of the pair of scores are formed by forming grooves on the inner surface side of the shell, and are extended along the peripheral edge of the liner radially outwardly of the liner. Moreover, the liner has a thin-walled central section and a thick-walled peripheral edge section, and is configured to have a downwardly protruding outer sealing ridge formed in a radially outward region of the thick-walled peripheral edge section. The thickness of the thin-walled central section and the thickness of the thick-walled peripheral edge section are set within required ranges.
