Abstract

A low cost container for reducing oxidation, as well as moisture migration and greatly delaying spoilage of fruits, vegetables, prepared foods, spices and other foodstufs as well as protecting hardgoods. An inner partition of pliable material having a resealable opening is located within an outer partition of pliable material. The fruits, vegetables, spices, prepared foods or other foodstuffs are placed within the inner partition through the resealable opening. Between the inner partition and outer partition, gaseous and/or liquid matter is provided such that when compressive force is applied to the outer partition, the inner partition evenly conforms to the shape of its contents, evacuating air and excess liquid therein. Valves may be incorporated and connected to the respective partitions to control the flow of the gaseous and/or liquid contents into or out of each respective partition.
