The present disclosure generally relates to containers and container end closures, and more specifically metallic end closures for small diameter metallic beverage containers. The present disclosure also relates to the tooling used to form the novel end closure, where the tooling is itself novel. The change of the angles on the die core ring improve the mobility of the metal while forming the end closure. Specifically, when manufacturing the new end closure with the new tooling, the press output is increased by over five times.

A can end including a central panel and a coined rivet disposed on the central panel. A press, a station, and/or a tooling assembly structured to form a coined rivet as well as a method to form the coined rivet is also provided.

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.

An end closure for food and beverage containers provides controlled opening characteristics to prevent the unintentional missiling of a tear panel. The end closure comprises a score line that defines a portion of the tear panel, and the end closure may comprise one or more anti-missile features that inhibit the propagation of a fracture down a score line, which reduces the likelihood that a tear panel will inadvertently detach from the end closure and injure the user or another.

After holding a metal pipe 10 using a clamping die 5, a primary formed portion 11a corresponding to the preforming surface portion 5c is formed on the metal pipe 10 by pressing an end portion of the metal pipe 10 with a pressing die 6 in a direction of a cylinder center line C1. A final formed portion 11b is formed on the metal pipe 10 by moving an outer forming die 7 to press an outer circumferential surface of the metal pipe 10 with the outer forming die 7 after aligning a rib portion 7c with the primary formed portion 11a, while moving an inner forming die 8 to press an inner circumferential surface of the metal pipe 10 with the inner forming die 8 after aligning a recessed groove portion 8c with the primary formed portion 11a.

A drawn and wall ironed beverage can body, method for forming same, and a sealed and filled can, include a through-hole or aperture in the base. A grommet for charging a propellant in can is located in the aperture. The aperture has a burr that is located on the inboard side of the rim of the aperture.

Equipment and related methods for manufacturing ring pull crowns are disclosed herein. In one embodiment, a method of manufacturing a ring pull crown may include forming a plurality of crown bodies from a first source material, and forming a plurality of pull ring and tab assemblies from a second source material. In addition, such a method may include forming a plurality of ring pull crowns by combining each crown body of the plurality of crown bodies with a corresponding pull ring and tab assembly from the plurality of pull ring and tab assemblies. Also, such method may also include forming a circumferential skirt that descends below a top of each ring pull crown, and removing the plurality of ring pull crowns from the first source material.
