PROBLEM TO BE SOLVED: To prevent contents of an object (especially wine or distilled liquor which requires suppression of oxidation) from degrading in quality even when outside air temperature and pressure change and from blowing to leak, and to store the object for a long time by sealing positive pressure gas in a bag, in a storage body for receiving the object in the bag for hermetically holding. SOLUTION: The storage body 1 comprises transparent film materials 2, 3 which are overlaid with four peripheral sides 6 heat-welded to provide a sealed bag body (a swelling part for injecting air). In preserving an object using such a storage body 1, the object (wine bottle for example) is inserted into an object storage part from an opening end 8 of the body 1, and the opening end 8 is closed by using a tape or by heat-welding. Deoxidation agent is put in the object storage part at the time of closing the opening end 8. Thereafter, after air in the storage part is removed through an injection valve 45, positive pressure gas such as inert gas or carbon dioxide gas is injected via the injection valve 45 into the object storage part, and then air of an atmospheric pressure of higher is injected via an injection valve 40 into the swelling part. |
