Abstract: Container filling apparatus having a novel, multi-purpose nozzle including a valve designed to control injection of a liquid or semi-liquid product into the container and a further means for evacuating any froth or foam from the container while simultaneously sensing when the level of product within the container reaches the predetermined full level. The valve comprises a hollow cylindrical body defining a chamber for receiving froth and foam and discharging same through a drain port. Passing longitudinally through this body member is a tubular piston having a product tube portion extending therefrom and dimensioned to fit through the neck of the container to be filled. The product tube has an exit port near its distal end and surrounding the product tube is a combination venting and level sensing tube. The space between the outside of the product tube and the inside of the venting/level sensing tube communicates with the froth/foam receiving chamber in the valve body.
