    摘要： A laminated steel sheet for use in the manufacture of a two-piece can body that satisfies the following three formulae includes a polyester resin layer on at least one side of the steel sheet, the polyester resin layer containing 3% to 30% by volume of dispersed incompatible subphase resin having a glass transition point of 5° C. or less and a cross section aspect ratio of 0.5 or less: d≦r; 0.1≦d/R≦0.25; and 1.5≦h/(R−r)≦4, wherein R denotes the radius of a circular laminated steel sheet that has the same weight as that of the two-piece can body before processing, h denotes the height of the can body, r denotes the maximum radius of the can body, and d denotes the minimum radius of the can body. A high strain two-piece can, such as a two-piece aerosol can, formed of the laminated steel sheet is free from delamination and breakage of the resin layer.

    摘要： A method of manufacturing an easy open end includes the steps of using a laminated steel sheet with resin films formed on both surfaces of the laminated steel sheet, and forming a panel structure and a score. A score die used for forming the score includes a scoring edge having a cross section in which a tip is a curve and two sides with the tip interposed therebetween are tangent to the curve. The tip is the curve having a curvature radius ranging from 0.2 to 0.4 mm, and the two sides have elevation angles θ in a range of 0.3≦tan θ≦1.0 to an end surface. The panel structure is formed by a motion that is synchronous with a motion in which the score die is pressed to a surface of the laminated steel sheet during the formation of the score.
