ABSTRACT:
The flexible storage bag includes overlaying first and second sidewalls defining an internal volume that can be accessed from an open top edge. To evacuate air from the internal volume after the open top edge has been closed, the bag includes a one-way valve element attached to the first sidewall and communicating with the internal volume. To prevent the one-way valve element from becoming clogged by the opposing second sidewall, the bag also includes a textured portion that maintains at least a partial clearance between the first and second sidewalls proximate the valve element. To prevent contamination of the valve element, the textured portion can also be configured to facilitate removal of liquids and juices from air exhausting from the storage bag.
