SHIPPING CONTAINER AND INSERT

摘要

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.

主权项

1. A shipping container assembly for transporting bulk particulate material comprising:
an outer container having an outer container storage cavity defined by an outer container base element and an outer container wall extending upward from said outer container base element; an inner container having an inner storage cavity at least partially defined by an inner container base portion and an inner container wall extending upward from said inner container base portion, wherein said inner container wall terminates at a peripheral edge that defines an inner container opening to said inner storage cavity, and wherein said inner container base portion has a smaller cross section than said inner container opening such that said inner container wall is tapered; wherein said inner container is configured to fit within said outer container storage cavity of said outer container so that said peripheral edge of said inner container wall contacts said outer container wall; and wherein, when said inner container is disposed in said outer container, said tapered inner container wall provides a lower surface of said outer container storage cavity.
