(57) [Problem] To provide an easy-to-manufacture and inexpensive refrigerant container without deteriorating refrigerant holding performance. SOLUTION: The refrigerant container 1 is composed of an outer container 11 and an inner container 12, and the outer container 11 and the inner container 12 have cylindrical portions 111, 121 and flat plate portions 112, 122 fitted at peripheral ends. Even if an external force acts on the plane of the flat plate portions 112 and 122, the fixing means 111a and 1a supports the flat plate portions 112, 122 against this external force, thereby preventing the flat plate portions 112, 122 from being depressed toward the hollow layer 13 side. Can be maintained. Moreover, using the cylindrical portions 111 and 121 and the flat plate portions 112 and 122 having simple shapes, Since it is not necessary to screw the flat portions 112 and 122 to the cylindrical portions 111 and 121 to reinforce them, material costs and processing costs can be reduced, and inexpensive products can be provided. |
