摘要： There is provided a method of manufacturing a cylindrical container using a metal sheet on at least one surface of which the metal is exposed. The method includes: obtaining a blank having a hexagonal shape from the metal sheet; and processing the blank into a cylindrical shape by pressing a central part of the blank with a punch in a state in which a peripheral part of the blank is clamped between a die for drawing process and a blank holder. The method is characterized by the following features. At least one of the die for drawing process and the blank holder has a groove-formed area at a portion of a surface thereof. The portion corresponds to a side of the blank. The groove-formed area is formed with a plurality of grooves along the circumferential direction. The blank is processed into the cylindrical shape by clamping the peripheral part of the blank between the die for drawing process and the blank holder so that the surface of the blank on which the metal is exposed is in a state of facing the groove-formed area and the side of the blank is in a position that corresponds to the groove-formed area.

摘要： Provided is a container-use surface treated steel sheet which is manufactured without using chromium and exhibits excellent working adhesion with a coated organic resin, a method of manufacturing the container-use surface treated steel sheet, an organic resin coated surface treated steel sheet. The container-use surface treated steel sheet is a surface treated steel sheet where nickel plating is applied to at least one-side surface of surfaces of a steel sheet by coating, wherein nickel plating has a fine particle shape formed by fine particles which has particle density of 2 to 500 pieces/μm2 and having an average particle size of 0.05 to 0.7 μm. The container-use surface treated steel sheet is also characterized in that a coating weight of the nickel plating of the container-use surface treated steel sheet is 0.1 to 12 g/m2, metal tin is contained in coating of the nickel plating, and an amount of metal tin is 0.05 to 0.1 g/m2. The organic-resin-coated surface treated steel sheet of the present invention is characterized in that an organic resin layer is formed on at least one surface of the container-use surface treated steel sheet. The metal can is formed by working the organic-resin-coated surface steel sheet.
