PURPOSE:To make it possible to be folded at the time of transport or storage, and at the same time, add a sufficient heat-insulating property by constituting a transport container of inner and outer, double and hollow mat shaped heat insulating walls. CONSTITUTION:A bottom wall 1 and peripheral side wall 2 which continues from the bottom wall 1 are respectively formed into a double hollow mat shape, with an internal film 3, intermediate film 4 and external film S. An internal side air chamber 6 and external side air chamber 7 which are formed between the internal film 3 and intermediate film 4, and between the intermediate film 4 and external film 5 are respectively constituted of a group of small chambers 9 which are mutually air permeable. A fused line 15 between the internal film 3 and intermediate film 4, and a fused line 16 between the intermediate film 4 and external film 5, which divide the small chambers 9, are alternately formed in such a manner that they are not aligned on the same line at the inside and outside, and the inside or outside of respective fused lines 15, 16 is covered by the small chamber 9. Then, an air injection valve is provided on at least one of both air chambers 6, 7, or a gas generator is encapsulated. At the time of usage, air or carbon dioxide gas is filled in the air chambers 6, 7, and the title container is expanded to its shape. |
