A valved filling head for filling a container with a viscous flowable product includes means for introducing a controlled blast of fluid through the head toward the fill opening or spout of the container at the end of the fill cycle. The fluid stream is directed against accumulated viscous material in the fill opening, in order to push the viscous material down into the container away from the spout and to prevent splattering of the material onto the container and over filling apparatus when the head and spout are separated and the opening is capped.
