Abstract: An easily-openable container lid made from a laminate material which includes a thick outer thermoplastic layer, a thin intermediate gas barrier layer, preferably of metallic foil, and a heat-sealable inner coating or film layer. A score line extends only partially through the outermost layer of this container lid to define an openable section thereof. The lid is further provided with a pull tab severing laminate material along its score line without delaminating, said tab being affixed to the openable lid section with a hollow, integrally-formed rivet. A retortable container and laminate lid combination is also disclosed.
