ABSTRACT:
A container assembly for bulk materials and a kit for assembling same are disclosed. A forming member having a plurality of sidewalls defines an internal cavity for receiving bulk materials. The sidewalls are arranged relative to one another and are locked into position so as to define a geometric volume of predetermined shape, by means of a locking assembly. The locking assembly can be integrally attached to or can be separable from the sidewalls, and can form a bottom of the container assembly. A tubular sleeve of continuous material is sized to snugly engage and overlie substantially the entire outer surface area of the sidewalls. The sleeve provides the containment strength, while the forming member provides structural shape and stability to the container assembly. Additional layers of corrugated material or woven polypropylene material or their combination may be used as inserts engaging the inner peripheral sidewall areas of the forming member to provide additional strength to the container assembly. The forming member sidewalls may be freely slidable relative to one another or may be slidably affixed to one another by releasable glue.
