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 can end including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

A can lid includes a score line provided on an outer peripheral edge side of a disk-shaped panel portion; a rivet portion provided in the panel portion and adjacent to an inner side of the score line in a radial direction; a tab including an attachment portion including a rivet hole to be attached to the rivet portion, a tip portion continuous with the attachment portion, and a finger hook portion formed on a side opposite to the tip portion across the attachment portion; and an auxiliary score line formed in the panel portion and including a first part and a second part, the first part extending in an arc shape on an inner side of the rivet portion in a radial direction of the panel portion, the second part being continuous with the first part.
