HEAT INSULATING CONTAINER

WIPO Patent Application WO/2001/076431

A1

A heat insulating container having the outer surface formed of a synthetic resin such as a vacuum bottle, a cooler box, an ice box, a heat insulating cup, a heat retaining lunch box, and a heat insulating and retaining storage container capable of preventing such problems that an available volumetric space is small as compared with large outside size because a thermal insulating effect must be increased, a metallic container causes a problem with corrosiveness, and synthetic resin container does not allow to be washed efficiently because the container is floated on a bath water surface at the time of washing, wherein a metallic container-like inside wall body (2) and a metallic container-like outside wall body (3) are disposed through a space part (4), the opening end parts (2a, 3a) of these wall bodies are formed integrally of each other, and at least one of the inner and outer surfaces of a thermal insulating layer body (1) formed by vacuating the space part (4) is covered by a synthetic resin inside container (11) or an outside container (12) and formed integrally of each other so as to increase a specific gravity.
