Document Type and Number:
Japanese Patent JP7111409
Kind Code:
B2
Abstract:
A vacuum freshness preservation container that can be pressed on two sides provided in this application includes a container body and container cove. The container cover has chambers disposed symmetrically, a piston is slidably disposed in each chamber, and each chamber has an air outlet which communicates with an interior of the container body and where a first check valve is disposed. The piston is provided with an air discharge structure that communicates the chamber with an outside when the piston moves toward the first check valve, and the container cover is provided with a linkage mechanism such that the two pistons move in opposite directions. By alternately pressing pistons in two chambers, the chambers always keep in a vacuumizing state, thereby achieving a higher efficiency.
