Zusammenfassung: | PROBLEM TO BE SOLVED: To prevent paint on a fixed edge from coming off by a level difference formed by seam welding. SOLUTION: This storage can is made of a cylindrically roll formed steel sheet 27 whose both peripheral ends 28 are mutually seam welded and has a cope plate wound on the bottom part of the can. The can is provided with a curved fixed edge part 11 wound and protrusively formed on the outside of an opening positioned highest and a curved bead 12 outwardly and protrusively formed on the lower level of the edge part 11. Furthermore, the cans are stackable vertically by fitting the bead 12 of one can 1 to be stacked on top on the edge part 11 of another can 1 receiving from underneath. The bead 12 protrudes less outwardly around the seam welded peripheral edge ends 28. COPYRIGHT: (C)2008,JPO&INPIT |
