Abstract: A one-way valve allows air to be drawn from a collapsible, flexible, air-tight bag using a vacuum source. When the vacuum source is removed, the one-way valve prevents air from re-entering the bag. A filter is placed on the valve body to prevent small particles from the bag from clogging the valve or the vacuum source.
Abstract: A flexible, evacuable storage bag has a storage portion, an airtight seal, and a one-way valve. The valve includes a strip sandwiched between top and bottom sheets used to make the bag. The strip is bonded along the edges to the top and bottom sheets so as to form a single passageway extending from the storage portion to outside the bag.
Abstract: A flexible, evacuable storage bag has a storage portion, an airtight seal, and a one-way valve. The valve includes a strip sandwiched between top and bottom sheets used to make the bag. The strip is bonded along the edges to the top and bottom sheets so as to form two passageways extending from the storage portion to outside the bag.
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.
