an apparatus for and a method of filling a flowable product into a succession of receptacles as they pass continuously along a predetermined path is defined by an elongated hollow containment member mounted above the predetermined path which is formed with an axially extending slot therein . a metering screw having a helical thread is mounted for rotation within the containment member and is biased into sealing engagement with the containment member on each side of the slot . a distribution chamber is formed within the containment member substantially around the screw member except that the sealing engagement and the slot whereby flowable products supplied to the distribution chamber when the screw is rotated is distributed through the slot between adjacent screw portions of the screw member and leaves the containment member in a succession of spaced moving streams .
