Abstract
A fluoropolymer coated article includes a fluoropolymer coating layer formed on a surface of a substrate. The fluoropolymer coated article has a concave formed on a fluoropolymer coating layer side surface of the fluoropolymer coated article. The concave is inlaid with a fluoropolymer composition containing a pigment. This fluoropolymer coated article can be used in for example an inner pan of a rice cooker, in order to indicate a scale, marks or letters which is very easy to see and which is excellent in durability and in corrosion resistance, while maintaining nonadhesiveness of the fluoropolymer coating.
Claims14
A fluoropolymer coated article comprising a substrate having at least one surface, a fluoropolymer coating formed to completely cover said at least one surface of the substrate, and a concave portion formed on a fluoropolymer coating side surface of the fluoropolymer coated article and recessed from said fluoropolymer coating, said concave portion being inlaid with a composition consisting essentially of a fluoropolymer and a pigment, said fluoropolymer coating and said fluoropolymer contained in said composition being fusion-bonded to each other so as to be integral with each other.
A fluoropolymer coated article comprising a substrate having at least one surface, a fluoropolymer coating formed to completely cover said at least one surface of the substrate, and an indicator formed on said fluoropolymer coating, said fluoropolymer coating having a concave portion recessed from said fluoropolymer coating, said indicator being formed of a composition consisting essentially of a pigment and a fluoropolymer and being inlaid into said concave portion, said fluoropolymer coating and said fluoropolymer contained in said composition being fusion-bonded to each other so as to be integral with each other.
An inner pan of an electric rice cooker comprising a fluoropolymer coating formed to completely cover an inner wall of the inner pan, and an indicator formed on said inner wall of the inner pan, said inner wall of said inner pan having a concave portion which is formed on said inner wall of said inner pan and which is covered with said fluoropolymer coating, said indicator being formed of a composition essentially consisting of a pigment and a fluoropolymer and being inlaid into said concave portion, said fluoropolymer coating and said fluoropolymer contained in said composition being fusion-bonded to each other so as to be integral with each other.
