PURPOSE:To obtain a can for canned goods having an extraordinary solid and beautiful view, easy to grip on a can body and resistant enough against hitting by a method wherein a panel and a frame exist alternately in a can axial direction and a can peripheral direction, either one of the panel and the frame is molded by squeezing and the panel and the frame are respectively positioned on a cylindrical surface the diameter of which is different from each other. CONSTITUTION:A can consists of a can body 1 and top and bottom winding parts 2a and 2b. In the can body 1, a reinforcing structure 4 is introduced in a central part, leaving non-treated cylindrical parts 3a and 3b from the top and bottom winding parts 2a and 2b. The reinforcing structure consists of a panel 5 and a frame 6. The frame 6 is a non-treated part and has the same diameter as the cylindrical parts 3a and 3b. The panel 5 is a molded part molded by squeezing and has a smaller diameter than the non-treated frame 6. A staged part 7 formed by the squeezing molding exists between the frame 6 and the panel 5. The panel 5 is square, and the frame 6 surrounds the panel 5 and extends slantwise (in a spiral direction), so that the panel 5 and the frame 6 can cross each other. |
