    摘要： The laminated metal sheet for can end is formed by laminating polyester film on both sides thereof, thus providing excellent appearance after retorting. The polyester film laminated to a side to become outer face of the formed can end has (1) half-time of crystallization of the resin of amorphous polyester layer formed near the interface between the polyester film and the metal sheet of 40 seconds or smaller at 130° C., (2) thickness of the amorphous polyester layer from 0.5 to 8 μm, (3) water vapor transmissivity of the polyester film of 100 g/m2/24 hr or smaller. The amorphous polyester layer resin is preferably a polyester composition prepared by formulating a polyester (I) (30 to 60% by weight) composed mainly of ethylene terephthalate as the main repeating unit, and a polyester (II) (40 to 70% by weight) composed mainly of butylene terephthalate as the main repeating unit.

    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.

    摘要： We manufacture a two-piece can by the method using a laminated steel sheet as the base material, having the steps of: drawing a cylindrical blank for several times to form a can body in a shape of cylinder integrated with bottom; forming a tapered part extending outward from the can body in the radial direction thereof at the tip of the opening of the can body; applying diametral reduction to the tapered part to the diameter of the can body; and applying diametral reduction to the opening side of the can body to a diameter smaller than the diameter of the can body, while satisfying the formulae (1) and (2), 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 circular blank positional radius, r is the radius of the can bottom, and d is the radius of the tip of the opening.

    摘要： A open can end of laminated steel sheet has a score formed thereon by a scoring die. The scoring die has a scoring edge having a sectional shape of an inverted triangle. The scoring edge includes a tip formed of a curve having a radius of curvature of 0.2 mm or more and 0.4 mm or less. Two sides sandwiching the tip are tangent to the curve. A function tan θ of an angle of elevation θ of each of the sides with respect to a surface of the can end is 0.3 or more and 1.0 or less. The resultant a can end being an easy open can end.
