Proportion, tapered-end can

Abstract

A multi-piece metal cylindrical can with tapered ends including a double-seam joint creating a hermetic seal. The cylindrical can includes can ends, a side wall portion, a first transition portion and a second transition portion. The can ends each have a diameter that is less than the diameter of the side wall portion.

1 . A three-piece metal can combination comprising:
 a first circular can end having a first diameter;   a second circular can end having the first diameter;   a cylindrical can side wall having a height, a first end having substantially the first diameter, a second end having substantially the first diameter, a side wall portion having a second diameter greater than the first diameter, a first transition portion which extends from the first end to the side wall, a second transition portion which extends from the second end to the side wall portion and a seam which extends from the first end to the second end, wherein the second diameter is between 80% and 120% of the height, and the second diameter is between 105% and 120% of the first diameter; and   a double-seam joint which hermetically seals the second circular can end to the side wall.   
     
     
         2 . The can of  claim 1 , wherein the side wall is fabricated from steel. 
     
     
         3 . The can of  claim 2 , wherein the interior of the side wall is coated with an organic coating. 
     
     
         4 . The can of  claim 3 , wherein the exterior of the side wall is coated with ink. 
     
     
         5 . The can of  claim 4 , wherein the first end includes a rim and a foil closure adhered to the rim. 
     
     
         6 . The can of  claim 4 , wherein the first end includes a pop top. 
     
     
         7 . A two-piece metal can comprising:
 a cylindrical can side wall having a height, a first end having substantially the first diameter, a second end having substantially the first diameter, a side wall portion having a second diameter greater than the first diameter, a first transition portion which extends from the first end to the side wall and a second transition portion which extends from the second end to the side wall portion, wherein the first diameter is between 80% and 120% of the height;   a circular can end; and   a double-seam joint which hermetically seals the bottom circular can to one of the first or second ends.   
     
     
         8 . The can of  claim 7 , wherein the second diameter is between 105% and 120% of the first diameter 
     
     
         9 . The can of  claim 8 , wherein the side wall is fabricated from steel. 
     
     
         10 . The can of  claim 9 , wherein the interior of the side wall is coated with an organic coating. 
     
     
         11 . The can of  claim 10 , wherein the exterior of the side wall is coated with ink. 
     
     
         12 . The can of  claim 11 , wherein the can end includes a rim and a foil closure adhered to the rim. 
     
     
         13 . The can of  claim 12 , wherein the can end includes a pop top. 
     
     
         14 . A two-piece metal can comprising:
 a circular can end;   a cylindrical can side wall having a height, a first end having a first diameter, a second end having a second diameter, a side wall portion having a third diameter greater than the first and second diameters, a first transition portion which extends from the first end to the side wall and a second transition portion which extends from the second end to the side wall portion, wherein the second diameter is between 80% and 120% of the height; and   a double-seam joint which hermetically seals the bottom circular can to one of the first or second ends.   
     
     
         15 . The can of  claim 14 , wherein the third diameter is between 105% and 120% of the first diameter. 
     
     
         16 . The can of  claim 15 , wherein the side wall is fabricated from steel. 
     
     
         17 . The can of  claim 16 , wherein the interior of the side wall is coated with an organic coating. 
     
     
         18 . The can of  claim 17 , wherein the exterior of the side wall is coated with ink. 
     
     
         19 . The can of  claim 18 , wherein the circular can end includes a rim and a foil closure adhered to the rim. 
     
     
         20 . The can of  claim 18 , wherein the circular can end includes a pop top. 
     
     
         21 . A three-piece metal can comprising:
 a first circular can end having a first diameter;   a second circular can end having the first diameter; and   a cylindrical can side wall having a height, a first end having substantially the first diameter, a second end having substantially the first diameter, a side wall portion having a second diameter greater than the first diameter, a first transition portion which extends from the first end to the side wall and a second transition portion which extends from the second end to the side wall portion, wherein the first diameter is between 75% and 100% of the height.
