Abstract
Filling units for supplying small tanks or the like with gasoline, kerosene, or other flowable materials which attach to an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, manipulation of the displacer section vertically within the tank, as for example by sliding a section of the overall unit upward, accommodates all the liquid remaining in the funnel up to such predetermined level within the tank by occupying the volume previously occupied by the displacer section and thereby completing the filling of the tank to a full condition without any spillage. The overall unit may be such that it is intended to be removed from the tank after each filling operation, or it may be designed to fit permanently within a wide-mouth tank inlet and to be movable downward to a storage orientation which allows the unit to remain mounted in the tank inlet and covered by the protective cap that normally screws onto the inlet opening to close it.
