摘要： In a method for producing a two-piece can, a circular disk of a laminated steel sheet having a thermoplastic resin coating layer is subjected to multistage forming to produce a final formed body having a height h, a maximum radius r, and a minimum radius d (the case where r is equal to d is also included). Forming is performed so that the height h, maximum radius r, and minimum radius d of the final formed body satisfy the relationships 0.1≦d/R≦0.25 and 1.5≦h/(R−r)≦4 with respect to a radius R of a circular disk before forming whose weight is equal to that the final formed body. At an intermediate stage of forming, a formed body is subjected to heat treatment at a temperature of not less than a melting point of a thermoplastic resin but not more than a temperature 30° C. higher than the melting point.

This method easily produces a can body for a laminated steel sheet two-piece can at a low cost without occurrence of peeling nor breakage of a resin.

摘要： A two-piece can has sufficient can strength and excellent corrosion resistance and to provide a method for forming the two-piece can easily without generating cracks.

There is formed a bead at the opening side of the can body, being curled outward from the can at the tip of the opening in a shape of circular arc or vertically long ellipse in cross section, and is further formed a bead having a cross sectional shape of further curled at the tip thereof, an upper bead, and a lower bead: 1.5≦h/(R−r)  (1) d/R≦0.25  (2) where, h is the height from the can bottom to the tip of the opening, R is the net blank radius, r is the radius of the can bottom, and d is the radius of the tip of the opening.
