ABSTRACT:
A collapsible, bag-like container, that incorporates the features of a rigid, free-standing container, with the flexibility and collapsibility of a bulk bag. Stiffening members are placed into pockets, created by sewing together two sheets of woven polypropylene. The stiffening members may be removed and placed inside the bag for shipping, and then installed in the sewn pockets to create a collapsible container, suitable for containment, and shipment, of bulk materials of up to seventy (70) percent liquid composition. The container side walls have flaps that can be folded onto the top of the container, and tied together with flexible tie elements, such that the container has a desired transverse reinforcement.
