Metallic container with a threaded closure
The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads that are formed after a threaded closure is inserted at least partially into the opening. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads.
1. A reclosable metallic container, comprising:
a container body comprised of a bottom portion, a sidewall portion, a neck portion extending upwardly from said sidewall portion, container threads that wrap at least one time around a portion of said neck portion, an opening positioned on an uppermost portion of said neck portion, and a curl formed on said uppermost portion of said neck portion, wherein said container threads include peaks that project inwardly from an interior surface of said neck portion, and wherein an exterior surface of said neck portion includes inwardly oriented valleys corresponding to said peaks; and
a threaded closure comprising:
a closure body adapted to be inserted at least partially into said opening of said neck portion;
closure threads formed on at least a portion of an outside surface of said closure body;
at least one seal adapted to contact a surface of said container body; and
a chamber with a perimeter sidewall defined by said closure body, wherein the chamber includes an upper opening which faces upwardly and away from said neck portion and is sealed with a cover.
2. The reclosable metallic container of claim 1 , further comprising a channel formed through said closure threads which is configured to allow the evacuation of a gas from within the reclosable metallic container after the threaded closure is rotated, wherein the channel is vertically oriented and extends through a lower thread of said closure threads.
3. The reclosable metallic container of claim 2 , wherein the channel extends through two threads of said closure threads.
4. The reclosable metallic container of claim 1 , further comprising a liner interconnected to a portion of said threaded closure, wherein said liner contacts at least a portion of said container body.
5. The reclosable metallic container of claim 1 , wherein a thread of said closure threads wraps at least 360° around said closure body.
6. The reclosable metallic container of claim 1 , wherein said threaded closure seals a product within said container body, wherein the container threads are formed before said threaded closure is rotated to open the container body.
7. The reclosable metallic container of claim 1 , wherein said container body is comprised of at least one of a steel, a tin, and an aluminum material, and wherein the threaded closure is comprised of at least one of a plastic and a metal material.
8. The reclosable metallic container of claim 1 , wherein said peaks of said container threads project at least partially into valleys of said closure threads.
9. The reclosable metallic container of claim 1 , wherein said container threads are formed by a thread roller that presses against the exterior surface of the neck portion.
10. The reclosable metallic container of claim 9 , wherein the thread roller presses said neck portion against said closure threads to form said container threads.
11. The reclosable metallic container of claim 1 , wherein the closure threads on the outside surface of the closure body contact the container threads projecting inwardly from the interior surface of the neck portion.
12. The reclosable metallic container of claim 1 , wherein said threaded closure further comprises:
an extension which is above the closure threads and projects outwardly from said closure body; and
a tamper indicator interconnected to said extension, the tamper indicator configured to engage the curl of the container body.
13. A reclosable metallic container, comprising:
a container body comprised of a bottom portion, a sidewall portion, a neck portion extending upwardly from said sidewall portion, container threads that wrap at least one time around a portion of said neck portion, an opening positioned on an uppermost portion of said neck portion, and a curl formed on said uppermost portion of said neck portion, wherein said container threads include peaks that project inwardly from an interior surface of said neck portion, and wherein an exterior surface of said neck portion includes inwardly oriented valleys corresponding to said peaks; and
a threaded closure comprising:
a closure body adapted to be inserted at least partially into said opening of said neck portion;
closure threads formed on at least a portion of an outside surface of said closure body;
at least one seal adapted to contact a surface of said container body;
an extension which is above the closure threads and projects outwardly from said closure body; and
a tamper indicator that is interconnected to said extension and which is configured to provide a visible indication when a seal formed between said threaded closure and said container body is broken.
14. The reclosable metallic container of claim 13 , wherein the closure threads on the outside surface of the closure body contact the container threads projecting inwardly from the interior surface of the neck portion.
15. The reclosable metallic container of claim 13 , wherein said peaks of said container threads project at least partially into valleys of said closure threads.
16. The reclosable metallic container of claim 13 , further comprising a channel formed through said closure threads which is configured to allow the evacuation of a gas from within the reclosable metallic container after the threaded closure is rotated, wherein the channel is vertically oriented and extends through a lower thread of said closure threads.
17. A reclosable metallic container, comprising:
a container body comprised of a bottom portion, a sidewall portion, a neck portion extending upwardly from said sidewall portion, container threads that wrap at least one time around a portion of said neck portion, an opening positioned on an uppermost portion of said neck portion, and a curl formed on said uppermost portion of said neck portion, wherein said container threads include peaks that project inwardly from an interior surface of said neck portion, and wherein an exterior surface of said neck portion includes inwardly oriented valleys corresponding to said peaks; and
a threaded closure comprising:
a closure body adapted to be inserted at least partially into said opening of said neck portion;
closure threads formed on at least a portion of an outside surface of said closure body;
at least one seal adapted to contact a surface of said container body; and
a tamper indicator interconnected to the closure body above the closure threads, the tamper indicator configured to engage the curl of the container body.
18. The reclosable metallic container of claim 17 , wherein said threaded closure further comprises a chamber with a perimeter sidewall defined by said closure body, and wherein the chamber includes an upper opening which faces upwardly and away from said neck portion and is sealed with a cover.
19. The reclosable metallic container of claim 17 , wherein said threaded closure further comprises an extension which is above the closure threads and projects outwardly from said closure body, and wherein the tamper indicator is interconnected to said extension and is configured to provide a visible indication when a seal formed between said threaded closure and said container body is broken.
20. The reclosable metallic container of claim 17 , further comprising a channel formed through said closure threads which is configured to allow the evacuation of a gas from within the reclosable metallic container after the threaded closure is rotated, wherein the channel is vertically oriented and extends through a lower thread of said closure threads.
