Abstract

The present invention relates to a method of manufacturing a metal vessel by way of stamping of vertical halves from a metal sheet, and in particular to a method comprising: stamping at least a first vessel half and a second vessel half from a metal sheet; adhering at least the first vessel half with the second vessel half forming a vessel, the vessel being a single piece article having an opening on one end for ingress and egress of a liquid or a gas and having a seam along two of the vessel vertical walls and along the bottom of the vessel where the first vessel half and the second vessel half make contact; and applying a top finish at the opening of the vessel allowing for a closure to be used to seal and selectively reseal the vessel.

First claim

What is claimed is:

1. A method of manufacturing a metal beverage vessel comprising:
stamping a metal sheet having an initial thickness to form vessel halves;
determining that the vessel halves do not have a polymer coating;
based on the determination, cleaning the vessel halves with commercial cleaner;
adhering the cleaned vessel halves together to form the vessel, the vessel adapted to contain a beverage and having an open end from which the beverage is to exit the vessel and a seam along vertical walls and bottom to contain the beverage within the vessel;
applying a decoration to an outside of the vessel;
applying a protective coating to an inside of the vessel;
curing the decoration on the outside of the vessel and the coating on the inside of the vessel simultaneously; and
forming a top finish at the open end adapted to receive a closure to seal the beverage within the vessel.

2. The method in accordance with claim 1 , further comprising selecting the top finish among one of a threaded outsert for receiving a screw cap closure, an insert for receiving threaded and snap closures, a flanged top for receiving a can top end, or a rolled top for receiving a crown type closure.

3. The method in accordance with claim 1 , wherein the stamping a metal sheet comprises
stamping the metal sheet into a first half having a first shape; and
stamping the metal sheet into a second half having a second shape asymmetric from the first shape.

4. The method in accordance with claim 1 , wherein the metal sheet is aluminum, aluminum alloy, steel, or a steel alloy.

5. The method in accordance with claim 1 , wherein the adhering comprises adhering by way of ultrasonic welding, magnetic pulse welding, laser welding, adhesive bond, or mechanical fit between the vessel halves.

6. The method in accordance with claim 1 , wherein applying the protective coating to the inside of the vessel comprises coating the inside of the vessel to form a barrier between a surface of the vessel and contents placed inside the vessel.

7. The method in accordance with claim 1 , wherein the vessel is capable of containing the beverage at pressures less than 100 psi.

8. The method in accordance with claim 1 , wherein applying the decoration to the outside of the vessel comprises decorating the vessel with a graphic, varnish, or shrink sleeve, wherein the graphic is applied by way of at least one roller or ink jet capable of applying a plurality of colors on a surface of the vessel.

9. The method in accordance with claim 1 , wherein forming the top finish at the open end adapted to receive the closure to seal the beverage within the vessel comprises, selecting a closure adapted to allow a consumer to open and reseal the vessel.

10. The method in accordance with claim 1 , wherein temporarily securing the vessel halves comprises one or more of:
ultrasonic welding;
magnetic pulse welding;
laser welding;
adhesive bond.

11. The method in accordance with claim 1 , further comprising precoating the metal sheet with polyethylene terephthalate (PET).

12. A method of manufacturing a metal beverage vessel comprising:
stamping a metal sheet having an initial thickness to form vessel halves;
confirming that the vessel halves do not have a polymer coating;
based on the confirming, cleaning the vessel halves with commercial cleaner;
adhering the cleaned vessel halves together to form the vessel, the vessel adapted to contain a beverage and having an open end from which the beverage is to exit the vessel and a seam along vertical walls and bottom to contain the beverage within the vessel;
forming a top finish at the open end adapted to receive a closure to seal the beverage within the vessel;
decorating an outside of the vessel with a graphic or varnish;
applying a protective coating to an inside of the vessel;
curing the graphic or varnish and the protective coating simultaneously; and
identifying defects in the vessel,
wherein the vessel is capable of containing the beverage at pressures less than 100 psi.

13. The method in accordance with claim 12 , wherein cleaning the vessel halves with commercial cleaner comprises:
precleaning the vessel halves;
rinsing the vessel halves using methods comprising:
a cold water rinse; and
a deionized water rinse; and

drying the vessel halves.

14. The method in accordance with claim 12 , wherein cleaning the vessel halves with commercial cleaner includes rinsing the vessel halves, and drying the vessel halves.

15. The method in accordance with claim 12 , further comprising securing the vessel halves against each other in preparation for adhering the vessel halves together.

16. A method of manufacturing a metal beverage vessel comprising:
stamping a metal sheet having an initial thickness to form vessel halves;
determining that the vessel halves have a polymer coating;
foregoing cleaning of the vessel halves based on the determination that the vessel halves have a polymer coating;
temporarily securing the vessel halves such that the temporarily secured vessel halves can be transferred to adhering equipment;
transferring the temporarily secured vessel halves to the adhering equipment;
adhering the vessel halves together at the adhering equipment to form a vessel adapted to contain a beverage and having an open end from which the beverage is to exit the vessel and a seam along vertical walls of the vessel and bottom to contain the beverage within the vessel; and
forming a top finish at the open end adapted to receive a closure to resealably seal the beverage within the vessel,
wherein the vessel is capable of containing the beverage at pressures less than 100 psi.

17. The method in accordance with claim 16 , wherein the stamping a metal sheet comprises
stamping the metal sheet into a first half having a first shape; and
stamping the metal sheet into a second half having a second shape asymmetric from the first shape.

18. The method in accordance with claim 16 , wherein the metal sheet is aluminum, aluminum alloy, steel, or steel alloy.

19. The method in accordance with claim 16 , wherein the adhering comprises adhering by way of ultrasonic welding, magnetic pulse welding, laser welding, adhesive bond, or mechanical fit between the vessel halves.
