Abstract
A method for manufacturing a can body by forming a circular laminated steel sheet having a radius of Rincludes producing a form at least one time with a laminated steel sheet coated with a polyester resin, which has a plane orientation coefficient of 0.06 or less such that that the height h, the maximum radius r, and the minimum radius d of the form satisfy d≦r, 0.2≦d/R≦0.5, and 1.5≦h/(R−r)≦2.5, where R represents the radius of the laminated steel sheet having a weight equivalent to the weight of a final form; heating the resulting form at least one time at a temperature of 150° C. or higher, and lower than or equal to the melting point of the polyester resin; and working the heat-treated form into a form satisfying d≦r, 0.1≦d/R≦0.25, and 1.5≦h/(R−r)≦4.
