Claim 19:
20. An apparatus to seal a metallic container having a neck portion that is unthreaded with a threaded closure, comprising:
a first tool configured to apply a top-load to the threaded closure positioned in an opening of the metallic container, wherein the threaded closure comprises a closure body with an outer surface including closure threads, and wherein the metallic container includes a bottom portion, a sidewall portion, the neck portion that is unthreaded and which extends upwardly from the sidewall portion, and the opening positioned opposite to the bottom portion;
a second tool configured to apply a force to an exterior surface of the neck portion of the metallic container to form container threads on the neck portion of the metallic container which have a geometric profile which substantially coincides with the closure threads of the threaded closure; and
a mandrel operable to be inserted into an open chamber of the closure body, wherein the mandrel has a cylindrical exterior surface, wherein the mandrel has an exterior diameter that is variable,
wherein, when the mandrel is inserted into the open chamber of the closure body, the mandrel has a first exterior diameter, and
wherein, after the mandrel is positioned in the open chamber, the mandrel expands to a second exterior diameter to contact an interior surface of the open chamber, the second exterior diameter being greater than the first exterior diameter.
