Abstract
A vacuum storage system (40) for storing an article, comprises a sealable outer chamber (30) and a sealable inner chamber (20). The sealable outer chamber (30) has an evacuation valve (21) for connection to a suction device (48) for evacuation of said outer chamber (30). The sealable inner chamber (20) is adapted to receive said article and has a one-way valve (13) in communication with the outer chamber (30). The one-way valve (13) is adapted to open upon the application of suction to the outer chamber (30), thereby to enable evacuation of said inner chamber (20), but to close upon discontinuation of said suction.
