ABSTRACT:
A material handling system for effecting the transfer of powdered fluent material with respect to a container while preventing the escape of such material to a surrounding work environment. The system comprises a container having an opening in its top, a lower closure device secured to the container at its top movable between a closed position closing the container opening and an open position for permitting access to the interior of the container opening. An upper closure device is releasably attachable to the container above the lower closure device. At least part of the upper closure device is removed from the container to permit access to the container opening when the lower closure device is open. The system also includes a tubular head comprising an outer sleeve, and an inner tube mechanism inside the outer sleeve. The container is designed to be sealingly connected to the tubular head with the outer sleeve in sealing engagement with respect to the container when at least part of the upper closure device is removed from the container. The inner tube mechanism is movable axially relative to the outer sleeve between a raised position and a lowered position in which the inner tube means extends endwise down beyond the outer sleeve.
