Collapsible receptacle for flowable materials

摘要

A collapsible receptacle for handling flowable materials in semi-bulk quantities comprises a generally cylindrical container supported by a sling. The container features top loading and bottom discharge. The container can be constructed of a strong weave material. Preferably, the container is constructed of a unique laminate material formed of an inner liner of polybutylene film noncontinously adhered to an outer layer of woven polypropylene. The sling is constructed of straps of polyester webbing, which are sewn to the container so that support stresses are distributed between the sling and the container. In one embodiment, the sling includes a ring for supporting the bottom of the container and lift straps attached to the ring. The ring surrounds a unique discharge spout in the container bottom. In another embodiment, the lower ends of the lift straps include guide loops for a draw rope. The draw rope surrounds a wire tie which functions to gather and close the bottom of the container. Release of the wire tie and draw rope permits discharge of the contents across the entire bottom of the container.
