This invention provides a two piece can, which has satisfactory can body strength and excellent corrosion resistance, and a molding method which can easily produce the two piece can without causing cracking. The two piece can is formed of a laminated steel plate as a material and comprises a closed-end cylindrical can body part. The can body part on its opening side has been subjected to diameter reduction working to a diameter smaller than the diameter of the can body and satisfies the following formulae (1) and (2). On the can body part in its opening side, a bead part having an opening front end part curled in a sectionally arc form or a sectionally longitudinal elliptical form toward the outer side of the can and a foremost front end part having a further curled sectional form, and upper and lower bead parts are provided. 1.5 <= h/(R-r)...(1) d/R <= 0.25...(2) wherein h: height from can bottom to front end part of opening, R: radius of circular blank position, r: radius of bottom part, and d: radius of front end part of opening. |
