First Claim
1. A container comprising an upright hollow body having side walls, a front wall, a rear wall, and a top wall, means on said body providing an inlet opening at the upper end thereof, and a discharge door movably mounted on the lower end of said body for movement between closed and open positions, said door in the closed position thereof forming a bottom wall for said body and in the open position thereof allowing material in said body to discharge therefrom through the bottom end thereof, a generally L-shape support frame for supporting said container and having an upright portion and a base portion, and coacting means on said container and on said upright portion for pivotally supporting said container on said frame for movement between a position in which said base portion is engaged with said door so as to retain said door in a closed position and a position in which said door is in a clearance relation with said base portion so as to be movable to an open position.

Abstract
A down flow material handling system consisting of an upright box-like container, a generally L-shape frame having an upright portion on which the upper end of the container is suspended and a generally horizontal base portion which extends underneath the container, and a transport cart. The container has an inlet opening at its upper end and a discharge door at its lower end which is hingedly mounted on the container rear wall and is releasably maintained in a closed position by the base portion of the L-shape frame. The cart is operable to remove the container from a wall support on which it is normally hung, move the container to a discharge location, and support the container during pivotal movement thereof to a discharge position in which the discharge door is clear of the L-shape frame and moves downwardly to an open position under the weight of the contents of the container.
