Abstract: Embodiments of the present invention relate to domed metal containers, and more specifically to pressurized metallic food containers with liquid nitrogen wells and various closure mechanisms. In some embodiments, the metallic food containers are thin-walled aluminum and are pressurized using liquid nitrogen to maintain strength and integrity. The container can have a nitrogen well to receive liquid nitrogen and keep the liquid nitrogen away from the food stuff packaged in the container. In various embodiments, the metallic food container comprises a domed bottom portion shaped and sized to nest with a food stuff packaged in the container. In some embodiments, the container is sealed with a tear away lid, a screw-on lid, or a metallic end closure double seamed to the container.

Abstract: A tool to remove or insert cotter keys in insulator bells having an L-shaped handle, with at least one depression on a generally flat butt end surface of the handle, a generally cylindrical rigid L-shaped member extending from the distal portion of the handle that terminates at a distal end in a second generally cylindrical tab having a smaller cross section than that of the rigid member. The method involves leveraging the member on an insulator cap while the tab is in a cotter key or for insertion, pressing the handle butt end at a depression against the key. The handle may be formed of two halves, be a unified body of synthetic material, be pliable and have an ergonomic shape, and the tab can be any of a variety of cross sectional shapes. The handle and extension may also be integrally formed and be made of similar materials.
