Abstract: A container closure includes a generally planar body having a product side and a customer side. The container closure body defines a limited container opening and an actuation location. Further, the container body includes a force concentrating construction disposed adjacent the limited container opening.

Abstract: A shell 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.

Abstract: A tab is provided for a can end. The can end includes an end panel and a scoreline defining a tear panel in the end panel for providing an opening in the can end. The tab includes a body having first and second opposing ends, a nose portion located at or about the first end, a lift portion located at or about the second end, and a rivet receiving portion disposed proximate the nose portion. The rivet receiving portion includes a rivet hole. A first rivet extends outwardly from the end panel and fastens the rivet receiving portion of the tab to the can end. A second rivet extends outwardly from the end panel to cooperate with a portion of the body proximate the lift portion.

Abstract: A method of making a can end, which includes a recessed panel defined by an upwardly extending chuck wall, a peripheral scoreline disposed in a public side of the panel proximate to the base of the chuck wall, a tab fastened to the panel by a rivet, includes the step of employing tooling to form a pressure resistance bead extends around the panel inboard of the peripheral scoreline and outboard of the rivet. The tooling forms a saw tooth panel formation proximate to the pressure resistance bead inboard of the pressure resistance bead. Among other benefits, the pressure resistance bead and saw tooth panel formation created by the tooling and method combine to resist wrinkling or other undesired deformation of the can end.
