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.
