Abstract

A food or drink container kit includes a metal container including a round threaded neck having at least one integrally formed thread. The kit also includes a metal press-on, twist-off closure comprising a round skirt including a gasket material 5 located on at least a portion of the interior of the skirt, a seal forming between the neck and skirt when the closure is placed on the container and heated.

1 . A two piece container, comprising:
 a can end having an outside end diameter;   a can body formed from single sheet of metal joined with a seam to form a cylinder having a top end and a bottom end, the seam extending from the top end to the bottom end, the can body including a neck portion formed at the top end and a body portion;   the neck portion defining a can opening surrounded by a curled portion of the sheet metal and a threaded portion including at least one thread formed from the sheet metal adjacent to the curled portion;   the body portion having a variable-diameter side-wall extending from the neck portion to the bottom end, the side wall including a first lobe portion, a second lobe portion and a transition portion joining the lobed portions wherein the side-wall has a first diameter at the first lobe portion which is between 100 and 120% of the end diameter, a second diameter at the second lobe portion which is between 95 and 110% of the end diameter, and a third diameter at the transition portion which is between 80 and 95% of the end diameter; and   a double seam which hermetically seals the can end to the body portion.   
     
     
         2 . The container of  claim 1 , wherein the body portion has a length defined by the distance between the neck portion and the bottom end, the length being between 165 and 230% of the end diameter. 
     
     
         3 . The container of  claim 2 , wherein the curled portion is formed by curling an end portion of the sheet metal outwardly. 
     
     
         4 . The container of  claim 2 , wherein the curled portion is formed by curling an end portion of the sheet metal inwardly. 
     
     
         5 . The container of  claim 3 , wherein the curled portion forms a hollow toroid surrounding the opening. 
     
     
         6 . The container of  claim 4 , wherein the curled portion forms a hollow toroid surrounding the opening. 
     
     
         7 . The container of  claim 5 , wherein the toroid is a torus. 
     
     
         8 . The container of  claim 2 , wherein the thread wraps around the neck portion at least 1½ times. 
     
     
         9 . The container of  claim 8 , including a metal closure having a generally cylindrical side wall integrally formed with an end wall and integrally formed with a rim at the end of the side wall opposite the end wall, the closure further including a gasket material disposed within the closure to form a hermetic seal between the neck and closure when the closure is joined to the threaded portion, heated and then cooled. 
     
     
         10 . The container of  claim 9 , wherein the gasket material is disposed within the closure to permit the closure to be pressed onto the threaded portion to form a vacuum or hermetic seal between the closure and the neck portion when the container wall and closure are heated. 
     
     
         11 . The container of  claim 10 , wherein the gasket material hardens and forms around the first end when it is heated and then cooled. 
     
     
         12 . A two piece container, comprising:
 a can end having an outside end diameter;   a can body formed from single sheet of metal joined with a seam to form a cylinder having a top end and a bottom end, the seam extending from the top end to the bottom end, the can body including a neck portion formed at the top end and a body portion;   the neck portion defining a can opening surrounded by a toroid formed from the sheet metal and a threaded portion including at least one thread from the sheet metal adjacent to the toroid;   the body portion having a variable-diameter side-wall extending from the neck portion to the bottom end, the side wall including a first lobe portion, a second lobe portion and a transition portion joining the lobed portions wherein the side-wall has a first diameter at the first lobe portion which is between 100 and 120% of the end diameter, a second diameter at the second lobe portion which is between 95 and 110% of the end diameter, and a third diameter at the transition portion which is between 80 and 95% of the end diameter; wherein the body portion has a length defined by the distance between the neck portion and the bottom end, the length being between 165 and 230% of the end diameter; and   a double seam which hermetically seals the can end to the body portion.   
     
     
         13 . The container of  claim 12 , wherein the toroid is hollow and has a generally circular cross-section. 
     
     
         14 . The container of  claim 12 , wherein the toroid is hollow and has a generally elongated cross-section. 
     
     
         15 . The container of  claim 12 , wherein the threaded portion is a single thread which wraps around the neck portion at least 1½ times. 
     
     
         16 . The container of  claim 12 , including a metal closure having a generally cylindrical side wall integrally formed with an end wall and integrally formed with a rim at the end of the side wall opposite the end wall, the closure further including a gasket material disposed within the closure to form a hermetic seal between the neck and closure when the closure is joined to the threaded portion, heated and then cooled. 
     
     
         17 . The container of  claim 16 , wherein the gasket material is disposed within the closure to permit the closure to be pressed onto the threaded portion to form a vacuum or hermetic seal between the closure and the neck portion when the container wall and closure are heated. 
     
     
         18 . The container of  claim 17 , wherein the gasket material hardens and forms around the first end when it is heated and then cooled. 
     
     
         19 . A two piece container, comprising:
 a can end having an outside end diameter;   a can body formed from single sheet of metal joined with a seam to form a cylinder having a top end and a bottom end, the seam extending from the top end to the bottom end, the can body including a neck portion formed at the top end and a body portion;   the neck portion defining a can opening surrounded by a toroid formed from the sheet metal and a threaded portion including at least one thread formed from the sheet metal adjacent to the toroid which wraps around the neck portion at least 1½ times, the body portion having a variable-diameter side-wall extending from the neck portion to the bottom end;   the side wall including a first lobe portion, a second lobe portion and a transition portion joining the lobed portions wherein the side-wall has a first diameter at the first lobe portion which is between 100 and 120% of the end diameter, a second diameter at the second lobe portion which is between 95 and 110% of the end diameter, and a third diameter at the transition portion which is between 80 and 95% of the end diameter; wherein the body portion has a length defined by the distance between the neck portion and the bottom end, the length being between 165 and 230% of the end diameter; and   a double seam which hermetically seals the can end to the body portion.   
     
     
         20 . The container of  claim 19 , wherein the toroid is hollow and has a generally circular cross-section.
