Abstract
A storage system comprising: an evacuable and reclosable bag comprising a wall made of a flexible material and a one-way valve attached to said wall of said bag; a container having walls made of a material less flexible than the flexible material; and an attachment device that attaches the bag to the container such that at least a portion of the bag resides within the container. To use this storage system, compressible articles are placed inside the evacuable bag. Then the bag is hermetically sealed and evacuated. During evacuation, the shape of the compressible articles inside the bag conform to the shape of the container interior volume. In one embodiment, when the bag with compressed articles is removed from the container, its shape facilitates stacking. In another embodiment, the storage bag with compressed articles remains inside the container.
