ABSTRACT:
A material container for bulk material having a follower disposed therein. The diaphragm of the follower is coextensive with the transverse cross-section of the container. During the removal of bulk material from the container, the follower moves downwardly in constant engagement with the upper surface of the bulk material for wiping the interior surface of the container and for applying a downward force on the bulk material. When bulk material is being discharged into the container for the filling thereof, the follower may be held at the upper portion of the container. A central access opening is formed in the top wall of the container and a central opening is formed through the diaphragm of the follower directed in the axial direction of the container. A tube through which bulk material is conducted into the container for passage below the flexible follower is fixed to the follower in communication with the central opening thereof and is arranged to receive bulk material having passage through the access opening of the container.
