Abstract:
A nozzle comprising:a nozzle body having a proximal end and an insertion end and defining an inlet orifice at the proximal end thereof and an outlet orifice at the insertion end thereof, the nozzle body further being adapted to be attached at the proximal end thereof to an opening of a container and to be inserted at the insertion end thereof into an opening of a receiving vessel for dispensing a first fluid from the container into the receiving vessel from the inlet orifice to the outlet orifice thereof; a valve head disposed at the insertion end of the nozzle body for selectively opening and closing the outlet orifice of the nozzle body, the valve head comprising a flexible seal adapted to be compressed to sealingly abut against walls of the opening of the receiving vessel when the nozzle body is inserted into the opening of the receiving vessel for substantially preventing at least a second fluid from escaping at the opening of the receiving vessel; further comprising a venting device connected to the nozzle body and defining a vent discharge opening for venting the second fluid from the receiving vessel into the container through the vent discharge opening such that the second fluid is vented through the vent discharge opening of the venting device without traversing the first fluid in the container substantially during an entire time for a dispensing of the first fluid from the container into the receiving vessel; the container to which the proximal end of the nozzle body is attached, being substantially rigid; the container being closed other than through the nozzle; and both the venting device for the second fluid and the inlet orifice for the first fluid communicating simultaneously with the container.
