  • Patent number: 5228588
    Abstract: Disclosed is a thickness-reduced deep-draw-formed can formed of a metal plate having an organic coating. In this can, at least the inner surface organic coating is composed of a crystalline thermoplastic resin, the thickness of the barrel wall is made smaller than the thickness of the bottom, the thermoplastic resin of the barrel wall is molecularly oriented mainly in the axial direction, and the roughness of the metal surface of the barrel wall is larger than that of the metal surface of the bottom. Since the organic coating is crystalline and is molecularly oriented, the coating can resist processing deformation when the thickness is reduced by deep-draw forming and the coating is not damaged by a tool or the like at all, and therefore, the barrier property to corrosive components and the heat resistance are prominently improved.
