Claim 0:
1. An apparatus to seal a metallic container with a threaded closure inserted into an opening of the metallic container, comprising:
a first tool configured to apply a first force to the threaded closure positioned in the opening of the metallic container, the first force directed downwardly relative to a longitudinal axis of the metallic container, wherein a lower surface of the first tool that is adjacent to the threaded closure is generally planar;
wherein the threaded closure includes a closure body, an outer surface including closure threads, and an extension projecting outwardly from an upper end of the closure body at a first angle relative to the longitudinal axis;
wherein the metallic container includes a bottom portion, a sidewall portion, a neck extending upwardly from the sidewall portion, the neck being unthreaded, a curl formed at an uppermost end of the neck, and the opening positioned opposite to the bottom portion;
wherein the first tool is configured to initially contact an uppermost area of the threaded closure positioned between opposing portions of the curl of the metallic container; and
wherein the first force from the first tool is configured to elastically deform the threaded closure and alter the first angle at which the extension projects from the closure body; and
a second tool configured to apply a second force to an exterior surface of the neck of the metallic container to form container threads on the neck by pressing the neck against the closure threads, wherein the second tool is configured to apply the second force while the first tool applies the first force, and wherein the threaded closure is biased in an upward direction after the second tool forms the container threads.
