PUNCHING METAL (working or processing of wire B21F) ## 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. ## Claims ### Claim 1 A method of manufacturing a metal beverage vessel comprising: stamping a metal sheet having an initial thickness to form vessel halves having a wall thickness approximately equal to the initial thickness of the metal sheet; adhering the 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; and forming a top finish at the open end adapted to receive a closure to seal the beverage within the vessel. ### Claim 2 (depends on 1) 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. ### Claim 3 (depends on 1) 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. ### Claim 4 (depends on 1) The method in accordance with claim 1, wherein the metal sheet is aluminum, aluminum alloy, steel, or a steel alloy. ### Claim 5 (depends on 1) 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. ### Claim 6 (depends on 1) The method in accordance with claim 1, further comprising coating an inside of the vessel to form a barrier between a surface of the vessel and contents placed inside the vessel. ### Claim 7 (depends on 1) The method in accordance with claim 1, wherein the vessel is capable of containing the beverage at pressures less than 100 psi. ### Claim 8 (depends on 1) The method in accordance with claim 1, further comprising 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. ### Claim 9 (depends on 1) The method in accordance with claim 1, further comprising identifying defects in the vessel. ### Claim 10 A method of manufacturing a metal beverage vessel comprising: stamping a metal sheet having an initial thickness to form vessel halves having a wall thickness approximately equal to the initial thickness of the metal sheet; adhering the 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 the vessel with a graphic or varnish; curing the graphic or varnish; and identifying defects in the vessel, wherein the metal beverage vessel is capable of containing the beverage at pressures less than 100 psi. ### Claim 11 (depends on 10) The method in accordance with claim 10, further comprising precoating the vessel halves with polyethylene terephthalate. ### Claim 12 (canceled) ### Claim 13 (depends on 10) The method in accordance with claim 10, further comprising cleaning the vessel halves with commercial cleaner, rinsing the vessel halves, and drying the vessel halves. ### Claim 14 (depends on 10) The method in accordance with claim 10, further comprising securing the vessel halves against each other in preparation for adhering the vessel halves together. ### Claim 15 A method of manufacturing a metal beverage vessel comprising: stamping a metal sheet having an initial thickness to form vessel halves having a wall thickness approximately equal to the initial thickness of the metal sheet; precoating the vessel halves with a polymer such that further cleaning of the vessel halves is avoided; adhering the vessel halves together 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 seal the beverage within the vessel, wherein the metal beverage vessel is capable of containing the beverage at pressures less than 100 psi. ### Claim 16 (depends on 15) The method in accordance with claim 15, 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. ### Claim 17 (depends on 15) The method in accordance with claim 15, wherein the metal sheet is aluminum, aluminum alloy, steel, or steel alloy. ### Claim 18 (depends on 15) The method in accordance with claim 15, wherein the adhering comprises adhering by way of ultrasonic welding, magnetic pulse welding, laser welding, adhesive bond, or mechanical fit between the vessel halves. ### Claim 19 (depends on 1) The method in accordance with claim 1, further comprising coating each of the vessel halves with a polymer, and, in response to coating the vessel halves with the polymer, determining not to clean the vessel halves. ### Claim 20 (depends on 1) The method in accordance with claim 1, further comprising precoating the metal sheet with polyethylene terephthalate (PET). ### Claim 21 (depends on 1) The method in accordance with claim 1, further comprising, after the stamping and before forming a vessel halves, selectively cleaning each of the vessel halves. ### Claim 22 (depends on 10) The method in accordance with claim 10, further comprising, after the stamping and before forming a vessel halves, selectively cleaning each of the vessel halves.
