A can lid comprising: a main body comprising a laminate metal sheet, the laminate metal sheet comprising a metal sheet and a first resin film on a major surface of the metal sheet, the major surface having a score line delimiting an opening piece, the first resin film comprising a first resin layer comprising a dimer acid-copolymerized polyester resin and being amorphous; and a tab attached to the main body and adapted to cause a cleavage along the score line.

A method for producing a primary laminate including a tabstock by feeding a seal laminate comprising bottom food contact layers including a foil layer and a top polyester layer to a laminating station wherein either the foil layer of the underside of the polyester layer has been printed; simultaneously feeding a tabstock, which is narrower than the seal laminate, to the laminating station such that the bottom of the tabstock and the top polyester layer of the seal laminate come into contact to form a primary substrate, simultaneously feeding a plastic film stock; and continuously extruding a polymeric adhesive between the top face of the primary substrate and bottom surface of the plastic film stock.

A container lid comprising a frustum shaped sidewall, a chuck shoulder formed between an upper edge of the sidewall and a seaming panel, and at least one translative motion guide feature extending radially inward from the sidewall. A bottom (lower) edge of the sidewall can be closed by a bottom wall or rolled creating an open design. The frustum shaped sidewall and size of the translative motion guide features is designed to enable nesting of multiple container lids/caps. The lid is seamed to a container body. The lid and cap each include sealing surfaces designed to engage with one another creating a gas and liquid impervious seal, preferably capable of retaining pressure within a container. Alternatively, the translative motion guide feature can be integral with a frustum shaped container body, such as a cup.

A pull tab for a container lid includes a nose configured to apply downward pressure on a frangible region of the container lid, a rivet receiving portion adjacent to the nose that includes a rivet aperture therethrough, a lift portion located distally from the nose, and a finger hole located in proximity to the lift portion. Side edges of the finger hole include one or more upward bends, placed such that the lift portion is elevated relative to a bottom plane of the pull tab, thereby facilitating user actuation of the pull tab and enabling efficient stacking of a plurality of the container lids during manufacturing thereof to facilitate shipment and storage thereof. An indentation formed in the container lid cooperative with the lift portion provides additional grasping space. Novel methods of manufacturing are also disclosed.
