Abstract A bin for storing and transporting bulk material having a discharge opening located in one side wall and a door hingedly mounted on the side wall for movement to a closed position overlying the opening. A hinge is provided having horizontally disposed end pins on which the door is hung for up and down pivotal movement toward and away from the discharge opening. The construction of the hinge prevents the accumulation of contaminants and foreign matter around the door and enables the easy removal of the door from the bin.
