Method and assembly for preventing dripping of a liquid dispensing nozzle

In a liquid dispensing nozzle, the improvement which comprises:

• a conduit having a proximal end and an opposed distal end with a sidewall therebetween providing a channel through the conduit, the proximal end being connected to a handle of the nozzle and the sidewall having an aperture adjacent the distal end for dispensing a liquid;
• a valve means mounted in the channel at the distal end of the conduit adjacent the aperture in the sidewall and including:
• (i) a stopper to control a flow of the liquid through the aperture in the sidewall of the conduit;
• and
• (ii) a biasing means to move the stopper to close the channel of the conduit adjacent the aperture in the sidewall to prevent the liquid from exiting the conduit through the aperture in the sidewall after the nozzle has been deactivated;
• a venturi shut-off mechanism having a venturi tube extending along the channel of the conduit from the handle of the nozzle to a venturi opening in the sidewall of the conduit adjacent the aperture;
• an automatic shut-off sleeve slidably mounted around an outside surface of the conduit which acts to close off the venturi opening when the sleeve is fully forward in a closed position;
• and
• a plunger provided in the sleeve which extends into the venturi opening and seals the venturi opening so as to trigger the venturi shut-off mechanism to deactivate the nozzle and stop the flow of liquid in the nozzle.

• a venturi shut off mechanism for deactivating the nozzle, having a venturi tube extending along the channel of the conduit from the handle of the nozzle to a venturi opening in the sidewall of the conduit adjacent the distal end of the conduit, the improvement which comprises:
• a shut off sleeve slidably mounted around an outside surface of the conduit;
• a plunger mounted in the sleeve such that a ball of the plunger extends into the venturi opening when the sleeve is in the fully forward position and acts to close off the venturi opening such as to deactivate the nozzle;
• and
• a biasing means mounted around the outside surface of the conduit between the sleeve and the proximal end of the conduit to move the sleeve into the fully forward position when the nozzle is removed from a container.
