ABSTRACT:
A reusable, evacuable enclosure comprising a bag with an opening in which to place compressible articles, such as clothing or linen, and a one-way valve in a surface of the bag. Compressible articles may be placed in the bag and sealed from the surrounding environment by placing a seal across the opening. The excess air in the bag may then be removed by placing a cylindrical attachment of a household vacuum cleaner over the one-way valve. Once the excess air is extracted, a cap is placed over the valve to ensure a permanent seal. Removal of excess air reduces the size of the compressible article and inhibits the growth of insects and bacteria, which may damage the contents of the bag. Moreover, the enclosure is impervious to moisture, and so inhibits the growth of mildew.
