A flexible bulk container for the handling and storage of flowable materials having structural maintenance means attached to the inside surfaces of the container for providing structural support to the walls which comprise the container. The container is comprised of a plurality of walls attached together and defining an enclosure having a bottom and a top panel attached to the encircling enclosure. Several embodiments of the structural maintenance means are enclosed, the first one comprising a loops and rope combination attached to the inner surfaces of the flexible container. Loops are attached to each side of the flexible container on the inside surface at a plurality of levels. A rope is threaded through the loops on each level and its ends are attached. The rope is drawn through and adjusted in size so that it holds the container walls in a substantially vertical orientation. A second embodiment includes the use of panels arranged in a crossing formation and attached to the inside surfaces of the container walls. The third embodiment includes the use of flaps attached to each inside surface of each wall which extend from the walls toward the center of the flexible container. Each flap has a plurality of holes formed through the edge of the flap located toward the center of the container. A continuous rope is threaded through the holes in the flaps at each level and attached at its ends. A plurality of levels of the hole and rope combination are arranged on the flaps for providing the needed support to the container sides. For each embodiment, the container is filled with flowable materials and the structural maintenance means functions to provide an opposing force against the tendency of the flowable materials to push outwardly on the container, thereby maintaining the cubicle shape of the flexible container.
