Method of Manufacturing a Metal Vessel

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.

1 . A method of manufacturing a metal vessel by way of stamping of vertical halves from metal sheet, the 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   forming a top finish at the opening of the vessel allowing for a closure to be used to seal and selectively reseal the vessel.   
     
     
         2 . The method in accordance with  claim 1 , wherein the top finish is selected from the list consisting 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 first vessel half and the second vessel half are asymmetrical in shape. 
     
     
         4 . The method in accordance with  claim 1 , where in the metal sheet is aluminum, aluminum alloy, steel, or a steel alloy. 
     
     
         5 . The method in accordance with  claim 1 , wherein the step of adhering includes adhering by way of ultrasonic, magnetic pulse welding, laser welding, adhesive bond, or mechanical fit between at least the first vessel half and the second vessel half. 
     
     
         6 . The method in accordance with  claim 1 , further comprising:
 coating the inside of the vessel forming a barrier between the vessel metal surface and contents places inside the vessel.   
     
     
         7 . The vessel in accordance with  claim 1 , wherein the liquid or the gas is a carbonated beverage, the vessel being capable of containing without leak, deformation, or rupture the carbonated beverage having an internal pressure of less than 100 psi. 
     
     
         8 . The method in accordance with  claim 1 , further comprising:
 decorating the vessel with a graphic, varnish, or shrink sleeve, the graphic being applied by way of at least one roller or ink jet capable of applying a plurality of colors on the vessel surface.   
     
     
         9 . The method in accordance with  claim 1 , further comprising:
 identifying defects in the vessel by an inspection test.   
     
     
         10 . A method of manufacturing a metal vessel by way of stamping of vertical halves from metal sheet, the 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 where the first vessel half and the second vessel half make contact;   forming a top finish at the opening of the vessel allowing for a closure to be used to seal and or reseal the vessel;   decorating the vessel with a graphic or varnish;   varnishing the vessel side walls protecting decoration and metal surfaces;   curing the graphic or varnish on the vessel; and   identifying defects in the vessel by an inspection test.   
     
     
         11 . The method in accordance with  claim 10 , further comprising:
 precoating the first vessel half and the second vessel half with a polymer, wherein the polymer is polyethylene terephthalate.   
     
     
         12 . The method in accordance with  claim 10 , further comprising:
 cleaning selectively at least the first vessel half and the second vessel half.   
     
     
         13 . The method in accordance with  claim 12 , where the step of cleaning further comprising:
 cleaning at least the first vessel half and the second vessel half with commercial cleaner;   rinsing at least the first vessel half and the second vessel half; and   drying at least the first vessel half and the second vessel half.   
     
     
         14 . The method in accordance with  claim 10 , further comprising:
 securing the first vessel half against the second vessel half in preparation for adhering the first vessel half and the second vessel half together.   
     
     
         15 . A method of manufacturing a metal vessel by way of stamping of vertical halves from metal sheet, the method comprising:
 precoating the first vessel half and the second vessel half with a polymer such that further cleaning of the first vessel half and the second vessel half is avoided, 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 where the first vessel half and the second vessel half make contact; and   forming a top finish at the opening of the vessel allowing for a closure to be used to seal and or reseal the vessel.
