A nozzle assembly (44) for a filling machine, the nozzle assembly controlling foaming and dripping of the product during and after the filling operation. The nozzle assembly includes a nozzle body (46), a fixed filling tube (48), a movable tube assembly (50), and movable cam structure (52). The movable tube assembly is provided with a sealing foot (80) through which a bore extends, the body being interconnectable with a vacuum line (66) after the completion of the filling of a container (16) to prevent dripping on the container. The movement of the movable tube assembly (50) is controlled by gear structure (100) associated with a valve (38) which controls the discharge of material through the nozzle assembly, in such a manner that the nozzle assembly will be closed when the valve is closed.

A method of filling a container comprising the following steps: providing a source of fluent material, a generally vertically extending filling tube through which fluent material may be discharged into a container, a valve assembly between the source of fluent material and the filling tube, said valve assembly initially being in a closed position and shiftable to an open position, and a sealing foot movable relative to said filling tube and initially disposed in sealing relationship at the lower end of the filling tube; positioning a container below the filling tube; moving the container and tube relative to each other to position the lower end of the filling tube near the bottom of the container; simultaneously moving the valve assembly to the open position and moving the sealing foot away from the lower end of the filling tube; initiating the flow of fluent material from the source of fluent material through the valve assembly and through the filling tube into the container; moving the container and the filling tube relative to each other as the container is being filled; stopping the flow of fluent material from the source of fluent material through the valve assembly and through the filling tube into the container; and simultaneously shifting the valve assembly back to its closed position and moving the sealing foot back to its sealing position.
