Vacuum food storage container and method for using it

Abstract

A vacuum food storage container includes a bag body and a vacuum valve. The bag body is provided with a bag mouth; the vacuum valve is detachably mounted on the bag mouth; and a gas passage is provided on at least one side wall of the bag body. By providing the bag body and vacuum valve and providing the bag body with the bag mouth, the vacuum valve is detachably mounted on the bag mouth, and a gas passage is provided on at least one side wall of the bag body. The device can preserve food under vacuum by connecting the vacuum pump to the vacuum valve. In addition, during the vacuumizing process, the two side walls of the bag body are easily adsorbed together, resulting in the formation of bubbles at the bottom of the bag body, so that the gas inside the bag body cannot be discharged fully.
