  • Pressing iron soleplate having a hardened and coated surface
    Publication number: 20030177672
    Abstract: A soleplate for a clothes pressing iron, composed of: a metal sheet having a lower surface that will be directed toward fabrics to be ironed, a lower surface layer that extends form the lower surface and an interior region that is separated from the lower surface by the lower surface layer, the lower surface layer being mechanically hammer-hardened, or work hardened, to have a hardness greater than the hardness of the sheet prior to being mechanically hardened; and a coating that is hard and resistant to scratching covering the lower surface.

  • Method for making a two part reservoir and resulting reservoir
    Patent number: 6425198
    Abstract: A water reservoir for a clothes pressing iron, the reservoir being composed of two plastic parts, and a method for fabricating the reservoir by: simultaneously molding the two parts of one reservoir in a first injection molding step in two impressions of the same mold; and assembling the two parts together while, in a second injection molding step, injection molding a joint of plastic material between the two parts to connect the two parts together in a fluid-tight manner, wherein the two parts are assembled together and the second injection molding step is performed before complete crystallization of the two parts.
