A method for forming a two-piece can made of a laminated steel sheet, comprising the steps of: forming a can body in a shape of cylinder integrated with a bottom by applying repeated several cycles of drawing to a circular blank of the laminated steel sheet; characterized by: applying diametral reduction to the can body at the opening end side to a diameter smaller than the diameter of the can body to form a diametral reduction part, while satisfying the formulae and: 1.5 ≤ h / R − r d / R ≤ 0.25 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; and forming a bead by forming a first curled part on the diametral reduction part by curling the tip of the opening of the diametral reduction part of the can body outward from the can in a circular arc in cross section, followed by forming a second curled part on the diametral reduction part by curling a portion of the tip of the opening end side containing the first curled part and a portion of the diametral reduction part adjacent to the first curled part in a circular arc in cross section, wherein the forming of the bead further includes pressing, after the first and second curled parts are formed, the curled parts radially inward with respect to the can to create a vertically long ellipse in cross section, and wherein the bead is formed with a cross section which allows a mounting cap to be clinched and fixed to the can body in a subsequent step. forming a can body in a shape of cylinder integrated with a bottom by applying repeated several cycles of drawing to a circular blank of the laminated steel sheet; characterized by: applying diametral reduction to the can body at the opening end side to a diameter smaller than the diameter of the can body to form a diametral reduction part, while satisfying the formulae and: 1.5 ≤ h / R − r d / R ≤ 0.25 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; and forming a bead by forming a first curled part on the diametral reduction part by curling the tip of the opening of the diametral reduction part of the can body outward from the can in a circular arc in cross section, followed by forming a second curled part on the diametral reduction part by curling a portion of the tip of the opening end side containing the first curled part and a portion of the diametral reduction part adjacent to the first curled part in a circular arc in cross section, wherein the forming of the bead further includes pressing, after the first and second curled parts are formed, the curled parts radially inward with respect to the can to create a vertically long ellipse in cross section, and wherein the bead is formed with a cross section which allows a mounting cap to be clinched and fixed to the can body in a subsequent step. applying diametral reduction to the can body at the opening end side to a diameter smaller than the diameter of the can body to form a diametral reduction part, while satisfying the formulae and: 1.5 ≤ h / R − r d / R ≤ 0.25 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; and forming a bead by forming a first curled part on the diametral reduction part by curling the tip of the opening of the diametral reduction part of the can body outward from the can in a circular arc in cross section, followed by forming a second curled part on the diametral reduction part by curling a portion of the tip of the opening end side containing the first curled part and a portion of the diametral reduction part adjacent to the first curled part in a circular arc in cross section, wherein the forming of the bead further includes pressing, after the first and second curled parts are formed, the curled parts radially inward with respect to the can to create a vertically long ellipse in cross section, and wherein the bead is formed with a cross section which allows a mounting cap to be clinched and fixed to the can body in a subsequent step.
