  • Patent number: 10526109
    Abstract: 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/?m2 and having an average particle size of 0.05 to 0.7 ?m. 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.

  • Patent number: 8413478
    Abstract: A method of drawing and ironing a resin film laminated metal sheet for forming a can body having a bottom portion, a can wall portion and a flange-forming portion by drawing the resin film laminated metal sheet obtained by laminating at least one surface of a metal sheet with an organic resin film, followed by ironing by using a punch and a plurality of dies neighboring each other. The can wall is effectively prevented from being broken by a decrease in the thickness of the can wall, and drawn and ironed cans are efficiently formed having a thickness which is decreased as designed.

  • Patent number: 7878040
    Abstract: A method of drawn and ironed processing of a resin coated metal sheet, in which in the drawn and ironed processing of resin coated metal sheet, there can be obtained a can body of satisfactorily small wall thickness and at an opening edge part of the can body, the coating resin is free from any defect; and a resin coating drawn and ironed processed can produced thereby. There is provided a method of drawn and ironed processing of a resin coated metal sheet, comprising performing drawn and ironed processing of a resin coated metal sheet composed of a metal sheet having at least one major surface thereof coated with an organic resin with the use of a punch and a die into a can body, characterized in that ironing is conducted with the use of a punch having a small-diameter portion at its rear end so that the ratio of ironing at an opening edge part of the can body after shaping falls within the range of 0 to 15%.
