When the storage bag is used, the valve 7 is connected with air extraction equipment, so that the interlayer 6 is in a negative pressure state, and the storage bag 3 is adsorbed by the through hole 1 and is tightly attached to the inner wall of the inner container 2. After the air extraction is finished, the valve 7 is closed, and the storage bag 3 is always adsorbed on the inner wall of the inner container 2.

In one embodiment, as shown in fig. 1 to 3, the gland 4 includes an outer cover 41 and an inner cover 42, the outer cover 41 and the inner cover 42 are concentrically disposed, and an inner wall of the outer cover 41 and an outer wall of the inner cover 42 form a sealing groove 43 to be fitted to the feed port 11. Preferably, a seal ring 44 is provided in the seal groove 43. When the storage bag is installed, the inlet 11 is placed in the sealing groove 43, and the opening of the storage bag 3 is pressed against the upper end of the inlet 11 by the elasticity of the sealing ring 44.
