PROBLEM TO BE SOLVED: To keep the inner temperature efficiently by blocking transfer of heat from the inside to the outside or from the outside to the inside of a storage container. SOLUTION: The body 1 is formed by securing an exterior body 2 made of steel plate and an inner container 3 made of stainless steel at the opening. An inward joint, i.e., a flame part 5, and an outward joint, i.e., a flange part 9, are formed at the opening of the exterior body 2 and the inner container 3, respectively. The inner container 3 is inserted into the exterior body 2 and a heat insulating material 11 is sandwiched between the flame part 5 of the exterior body 2 and the flange part 9 and secured by means of screws 10. The heat insulating material 11 blocks transfer of heat from the inner container 3 to the exterior body 2 or from the exterior body 2 to the inner container 3 thus heat insulating the inside of the container efficiently.
