  • Patent number: 4478155
    Abstract: An improved container for bulk cargo is provided with a peripheral wall, a top, and a bottom. The top defines a longitudinally extending central ridge and the bottom defines two spaced, parallel, longitudinally extending skirts separated by a central recess. The contour of the top generally corresponds to the contour of the bottom such that multiple containers can be stacked one over the other. The container is provided with a perforated floor which simultaneously braces the peripheral wall against spreading and provides a support surface for palletized cargo and the like. The floor perforations allow bulk cargo to fall from the upper portions of the container to the lower portions of the container. A bulk cargo loading door is provided in the top along the uppermost portion of the central ridge, and two bulk unloading doors are provided along the lowermost portions of the skirts. In addition, end doors are provided for moving palletized cargo into and out of the container.
