An apparatus includes a tool operable to releasably join a metallic end closure to a metallic container. In one embodiment, the tool is configured to form a thread in the closure and the container. The tool may optionally crimp the closure to the container. Once sealed, the container can be opened by rotating the closure in an opening direction. The closure can subsequently re-close the container by rotating the closure in a closing direction.

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.
