熱中空体の製造方法。2. A method for manufacturing a heat insulating hollow body constituted by a hollow double wall structure having an inner wall and an outer wall, the hollow double wall having a reinforcing means for integrating the inner wall and the outer wall by blow molding. The hollow double-walled structure is formed with an introduction hole for a resin having an oxygen barrier property, and an oxygen barrier resin aqueous solution or mixture obtained by mixing the solvent or water with the oxygen barrier resin is formed through the introduction hole. A liquid is introduced, and then the hollow double-walled structure is rocked so that the aqueous solution or mixed solution of the oxygen barrier resin is evenly adhered to the entire inner surface of the hollow double-walled structure. The aqueous solution or mixed solution of the oxygen barrier resin in the hollow portion is discharged to form a film of the oxygen barrier resin on the inner surface of the hollow double wall structure, and then the air in the hollow portion is removed from the hollow double wall structure. Excluded and hollow double wall structure A method for producing a heat insulating hollow body, characterized in that a hollow heat insulating container is constituted by a hollow double-walled structure which is hermetically sealed in a vacuum state.
