A container includes a flexible liner for holding fluent material, a plurality of substantially vertical rigid support walls spaced around the periphery of the liner, and a flexible skin interconnecting the walls and encircling the liner so as to laterally constrain and support the liner when fluent material is added. The container can include a bottom wall under the liner and connected to some of the support walls. Furthermore, a top platform can be removably secured over the liner so as to rest on top of the support walls. This provides the strength and rigidity to make the container system stackable. The support walls can be removably disposed in pockets or a sleeve in the flexible skin.

[ What is claimed is:] [1.] A stackable collapsible container for storing flowable materials comprising:an outer body having a plurality of substantially vertical side walls joined together to form a continuous loop, at least some of the side walls being rigid and at least other of the side walls being flexible;a liner constrained by the side walls within the loop and adapted to hold flowable material;a substantially rigid top platform extending over the liner and resting on at least some of the rigid side walls so as to distribute a compression load among said at least some of the rigid side walls; andmeans detachably securing the top platform to the outer body;whereby the outer body can be detached from the top platform, collapsed, and folded for storage when the liner is empty; andwhereby the container also can be stacked when the liner is filled with flowable material, the flowable material bearing with an equal pressure on all of the side walls of the outer body so as to keep the side walls vertical and rigid for stacking.
