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 noncontinuously 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. In another embodiment, the receptacle includes a top panel, side panels and side seams between the side panels with the lift straps encompassing at least a portion of the side seams and attached to a top stitch to the top and side panels.

A cover for a hamper bag that is supported on a hamper stand is formed of a cloth panel shaped to overlie the top opening of the bag and also fit around the top of the hamper stand. A cloth skirt extends downwardly from the panel around a panel perimeter to fit around the outside of the upper region of the stand, and an elastic strip is arranged around the bottom of the skirt and dimensioned for stretching over and snapping in under the upper region of the stand for releasably holding the panel closed over the top opening of the bag. The panel, skirt, and elastic strip are all secured to the inside of the hamper bag below the top of the bag to be disposed along the upper region of the stand in a hingedly movable orientation.
