ABSTRACT:
A self-adjusting breather bag for use in sealed storage structures to limit the contact of ambient atmosphere with the stored material. The self-adjusting of the lower part of the bag to a higher position in the structure is accomplished by strategically assembling elastic or resilient members inside or outside the bag which automatically raises the lower portion of the bag when the bag is in a substantially non-inflated condition. A retracting device may be used to store the elastic or resilient members to provide for a greater range of inflation and retraction of the bag.
