Storage container with vacuum

摘要

A device comprises an upper section with a unidirectional flow valve and a lower section with a surface for adhering to a container with its own unidirectional flow valve and a passageway to circumscribe the container's unidirectional flow valve. A middle section of the device has a plurality of walls of which some may be at substantially acute angles that couple the upper section to the lower section to form a cavity between the unidirectional flow valve and the passageway.
