  • Patent number: 4711010
    Abstract: A method of sealing off a vaporization chamber provided in a soleplate of a steam iron by means of a cover is described. The vaporization chamber has an outer wall which has an upper edge remote from the bottom surface of the soleplate and having an upwardly opening continuous recess or groove provided therein. The method comprises placing the cover over the vaporization chamber in contact with the upper edge of the outer wall and applying high pressure to the cover, the cover material being forced into the recess to sealingly connect the cover to the soleplate before the pressure is released. There is no need for any additional sealing materials between the chamber and the cover and no need to screw or rivet the cover onto the soleplate.
