Abstract:
An anti-foam splash-proof nozzle for filling containers, comprising:a) an air gap section;b) a venturi section;c) a plenum intermediate said venturi section, said plenum being in communication with ambient air in the absence of water flow;d) said air gap section including:i) a hollow barrel having a water inlet and lateral openings;ii) an elastic sleeve surrounding said barrel and forming therewith a resiliently openable seal, said sleeve, when said seal is opened, defining a water path between said barrel and said sleeve into said plenum while at the same time sealing said plenum against ambient air; ande) said venturi section including:i) a venturi;ii) a water inlet from said plenum to said venturi;iii) a passage for conveying a foam-prone chemical into the throat of said venturi to mix it with water flowing through said venturi; andiv) an outlet adapted to communicate with a container to be filled;f) whereby said container can be filled with a minimum of foaming and no water leakage laterally of said nozzle.
