  • Patent number: 5153977
    Abstract: This invention relates to a method of making a double-walled thermally insulating metal container comprising an inner casing and an outer casing having an evacuation opening. A quantity of joining material is placed near or on the evacuation opening so as to cover the opening partially or completely. The assembly is treated in a vacuum furnace to evacuate the insulating space, to melt the joining material and to solidify the joining material in situ to provide vacuum sealing without resorting to a conventional sealing plate.
