The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads.
Claims16
A method of sealing a metallic container, comprising:
- providing a container body in a preferred shape, said container body comprised of a bottom portion, a sidewall portion, a neck portion extending upwardly from said sidewall portion, and an opening positioned on an uppermost portion of said neck portion;
- inserting a threaded closure into said opening of said neck portion, said threaded closure comprised of a closure body adapted to be inserted at least partially into said opening of said neck portion, said closure body having closure threads formed on at least a portion of an outer surface of said closure body;
- inserting a mandrel into a chamber formed in said closure body;
- and
- forming container threads on at least a portion of said neck portion of said container body by applying a force against an exterior surface of said neck portion to compress said portion of said neck portion against said threaded closure, wherein said mandrel supports said threaded closure when said force is applied against said exterior surface of said neck portion to form said container threads, wherein said mandrel is withdrawn from the chamber after said container threads are formed, and wherein said threaded closure is removably retained within said neck portion of said container body and seals a product within said container body.
A method of sealing a closable metallic container, comprising:
- providing a metallic container comprising a bottom portion, a sidewall portion, a neck portion extending upwardly from the sidewall portion, and an opening positioned on an uppermost portion of said neck portion;
- inserting a threaded closure at least partially into said opening of said metallic container, said threaded closure comprising a closure body, closure threads formed on at least a portion of an outside surface of said closure body, a chamber formed in said closure body, and at least one seal adapted to contact a surface of said metallic container;
- inserting a mandrel into the chamber formed in said closure body;
- and
- pressing a tool against an exterior surface of said neck portion to push said neck portion against said threaded closure to form container threads on a portion of said neck portion, wherein the mandrel supports said threaded closure when the tool is pressed against said exterior surface of said neck portion, wherein the mandrel is withdrawn from the chamber after said container threads are formed, wherein said threaded closure is removably interconnected to said opening of said metallic container by rotating said threaded closure, and wherein said threaded closure seals a product within said metallic container.
