ABSTRACT:
An evacuable storage container for holding compressible articles including a flexible, air-impermeable bag defining an interior and having first and second openings, a one-way valve mechanism sealingly positioned over the first opening, and configured to allow fluid to pass through the valve mechanism out of the bag and to substantially prevent fluid from entering the bag, and a zipper seal adjacent the second opening that is configured to substantially close the second opening. The zipper seal is integral with the bag and includes a first strip including at least one rib that extends from the surface of the first strip, and a second strip opposite the first strip, the second strip including at least two ribs that extend from the surface of the second strip and that are offset from the rib of the first strip such that the first and second strips may be sealingly engaged.
