Three-piece can

Abstract

A can for processed or non-processed foods is provided, for use by food companies or others, which is a three-piece can and which has a cylindrical shape. One of the ends is expanded (necked-out), thus top and bottom have different diameters, but within limits not to compromise rolling on flat surfaces and guides minimizing friction between the external part of the cylindrical body with the finish or artwork while rolling. The can may also be stacked, since it is provided with different diameters top and bottom, which fit in when stacked.

What is claimed is: 
     
         1 . A three-piece can comprising a cylindrical body, a top and a bottom, the cylindrical body being seamed to both top and bottom forming an upper seam and a lower seam respectively, wherein said cylindrical body comprises a first section having a first diameter (C), a second expanded section having a second diameter (D) larger than first diameter (C), said first and second diameters differing by 2 mm to 4 mm, and wherein the upper and bottom seams defining support edges for the can to be rolled on flat surfaces. 
     
     
         2 . The three-piece can of  claim 1 , wherein second expanded diameter (D) is 3 mm larger than first diameter (C). 
     
     
         3 . The three-piece can of  claim 1 , wherein the first section of cylindrical body has a first height (H2), the second expanded section has a second height (H1), and wherein the first height (H2) is 5 to 50 times the first height (H1). 
     
     
         4 . The three-piece can of  claim 1 , wherein the first section of cylindrical body comprises ribs.
