A shell, a container employing the shell, and tooling and associated methods for forming the shell are provided. The shell includes a center panel, a circumferential chuck wall, an annular countersink between the center panel and the circumferential chuck wall, and a curl extending radially outwardly from the chuck wall. The material of at least one predetermined portion of the shell is selectively stretched relative to at least one other portion of the shell, thereby providing a corresponding thinned portion. The tooling includes a pressure concentrating forming surface.

In accordance with one embodiment of the invention, there is provided an improved disposable aluminum pan for use with a chaffing rack and a pair of half pans. The pan includes a base terminating to a sidewall and an rim, which terminates to a rolled bead. The pan includes an inside length measured longitudinally across opposing sidewalls from the inside edge of the rim. The inside length is configured to be shorter than a corresponding inside length of an unimproved pan. The pair of half pans when nested side by side in the improved pan can have adjacent sides of the half pans lay without overlap. The pan also allows for a lid to fit better. The pan also includes a deeper well such that the bottom is positioned closer to burners in the chaffing rack and allows more water to be added during the heating process.

Ring pull crowns require equipment and related methods for manufacturing. A method of manufacturing a ring pull crown includes 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.

A container can end includes a concave dome shape and may forgo a peripheral reinforcing bead around the center panel. The tab may also be curved. Tooling for forming the end and a corresponding method are provided.

A cap of the press-twist type for a container, includes: a metal capsule having a transversal wall of longest extension which extends transversely with respect to an axis of the container, and a lateral wall; a curling in the distal part with respect to the transversal wall of the lateral wall by means of a curling operation; a sealing gasket with an annular shape for engaging with an opening of the container. The sealing gasket is made of a PVC-free material and includes a lateral portion, positioned in contact with the lateral wall of the capsule, which includes two portions away from the transversal wall of the capsule: a first distal portion relative to the transversal wall of the capsule and a second proximal portion relative to the transversal wall of the capsule, with a thickness greater than the first distal portion.
