Abstract
An improved material handling apparatus or container for transporting, storing, and unloading a load of powder, granular, particulate or other fluidizable material. The container has a pallet base which includes a discharge opening and an inclined load supporting deck with the discharge opening located at the lowermost portion of the deck at one side of the pallet whereby substantially all the fluidizable material in the container may be readily unloaded. The container includes a porous cloth diaphragm held in place overlying the deck by means of a retainer spline inserted into a groove in the pallet along with the diaphragm in such manner that the spline self-locks in the groove upon tension loading being applied to the diaphragm thus preventing the diaphragm from pulling free of the pallet during fluidization of the load. A vent valve is provided for maintaining pressure within the container during fluidization of the lead within a predetermined pressure range to maintain shape and structure while the container is being unloaded without limiting the flow of fluidizing air but preventing excessive pressure from being applied to the bag. Another embodiment of the container is disclosed which lessens the danger of explosion or fire due to the discharge of static electricity while handling potentially dangerous materials or while operating in dangerous environments.
