Abstract
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.
