Abstract
A system, apparatus, and method of storing food including a storage container having a base; a resilient liner nesting in the base, and a lid that interlockingly engages with the liner and/or base to close off access to foodstuffs retained in a compartment defined by the liner. A valve assembly in the lid is actuated by a pump to evacuate air from the liner's compartment and create a vacuum or near-vacuum condition therein. Apertures defined in the wall of the base allow air to flow into a compartment of the base as the resilient liner shrinks around the food. The closed storage container may be placed in a freezer to freeze the food therein. For defrosting, the base of the closed storage container is placed in a volume of water, some of which flows through the apertures in the base's wall and comes into direct contact with the liner.
