Abstract:
An air impermeable preservation container (1,2), includes an air impermeable hollow tubular cylinder (11,21) and a soft inner tube (17). The cylinder includes a main body (111,211), a front end (112,212) and a rear end (113,213) along the axial direction. A manual air extractor (114,214) is set on the front end for extracting air out. An air suction valve (115,215) is set on the rear end for sucking air inside. Assembling means (13,14,23,24) and sealing means (15,16,25,26) are set at connection part of the main body and the front end and at connection part of the main body and the rear end. The soft inner tube is accepted inside the main body. The external shape of the soft inner tube is generally the same as the internal shape of the main body. An accommodating zone (171) is formed inside the soft inner tube, and grooves (172) for air-escaping are formed on the external surface of the soft inner tube. Or at least one air bag (29) instead of the soft inner tube is accepted inside the main body. The air bag has a sealed elastic shuck, the internal space of which is full of air. When air pressure in the container decreases, the air bag expands to enlarge the volume.
