ABSTRACT:
A rectangular bin body having a top wall, front and back walls, side walls and bottom wall with an inlet opening in the top wall and a discharge opening in the front wall at the juncture of the front wall with the bottom wall and one of the side walls. The discharge opening is aligned with an internal corner of the bin at the juncture of the back and bottom walls with the one side wall so that when the bin is tipped upwardly about a generally horizontal axis located to one side of the bin and inclined with respect to the back the one side wall, the internal corner is located at an elevation below the remainder of the interior of the bin. In this position of the bin, the side walls, the back wall and the bottom wall function as a hopper to direct the bin contents to the internal corner so that the entire contents of the bin can be emptied by directing a suction tube inwardly of the bin straight through the discharge opening and into the internal corner. A discharge tube in the interior of the bin aligned with the discharge opening and directed toward the internal corner from which the bin is emptied, facilitates the insertion of the suction tube into the bin and ultimately into the internal corner of the bin from which the contents are removed. A valve assembly in the front wall of the bin enables samples of the bin contents to be removed without fully opening the bin.
