A shipping container for transporting bulk particulate material includes an outer container and an inner container with tapered sides that taper or narrow downward towards a bottom portion of the inner container. As a vacuum removes particulate material from at the bottom portion of the inner container, material higher up in the outer container and/or inner container funnels downward towards a central region at the bottom portion of the inner container and near the mouth of the vacuum tube or hose, filling a void created by the extracted material that is drawn up the tube or hose. The inner container provides a continuous flow of material to the vacuum hose or tube and a more complete emptying of the container, without having to tilt the shipping container or move the vacuum hose or tube in the shipping container. |
