ABSTRACT:

The bottom of a container has a discharge-fill opening, and the top has an air inlet controlled by a selectively activated air inlet valve. Opening this valve adds the contents of the container to that of the surrounding tank. The valve can be restored to closed position by buoyancy forces on the following tank fill.
