<p>The interior of the container has at lest one movable partition which is normally adjacent a wall of the container and, in use can be moved towards a discharge opening of the container. The partition may be of a flexible material connected at its edges to the wall of the container. Compressed air is admitted to move the partition to form a funnel at the discharge opening. In an alternative construction, the partition may be a piston which is moved longitudinally in a horizontal cylindrical tank, for example of a tanker vehicle.</p> |
