Vapor recovery nozzle

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 venting path connected to the nozzle body and defining a vent discharge opening for venting a second fluid from the receiving vessel into the container through the vent discharge opening such that a second fluid is vented out of the receiving vessel through the vent discharge opening of the venting path 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;
• comprising an attachment mechanism coupled to the nozzle body for removably attaching the nozzle body to the opening of the container;
• wherein the attachment mechanism is configured for removably sealingly attaching the nozzle body to the opening of the container for substantially preventing the first fluid and the second fluid from escaping at the opening of the container;
• and
• wherein the proximal end of the nozzle body defines a flange, and the attachment mechanism comprises:
• a cap ring threaded on inner walls thereof for attachment to corresponding threads on the opening of the container, and a cap ring seal abutting at one side thereof against the cap ring and on another side thereof against the flange of the proximal end of the nozzle body, the cap ring seal and the cap ring being effective for providing a sealed attachment of the nozzle to the opening of the container for substantially preventing the first fluid and the second fluid from escaping at the opening of the container.

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;
• and
• wherein the venting device comprises a sound generating mechanism thereon adapted to generate a sound during a venting of the second fluid into the container.

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 venting path connected to the nozzle body and defining a vent discharge opening for venting a second fluid from the receiving vessel into the container through the vent discharge opening such that a second fluid is vented out of the receiving vessel through the vent discharge opening of the venting path 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 being substantially rigid;
• the container being closed other than through the nozzle;
• and
• both the venting path for the second fluid and the inlet orifice for the first fluid communicating simultaneously with the container.

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 venting path connected to the nozzle body and defining a vent discharge opening for venting a second fluid from the receiving vessel into the container through the vent discharge opening such that a second fluid is vented out of the receiving vessel through the vent discharge opening of the venting path 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;
• and
• wherein the venting path comprises a sound generating mechanism thereon adapted to generate a sound during a venting of the second fluid into the container.

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 venting path connected to the nozzle body and defining a vent discharge opening for venting a second fluid from the receiving vessel into the container through the vent discharge opening such that a second fluid is vented out of the receiving vessel through the vent discharge opening of the venting path 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;
• and
• wherein said venting path includes a vent inlet orifice at an end of said venting path closest to said insertion end of said nozzle body, said vent inlet orifice having a portion thereof most distant from the insertion end of the nozzle body closer to the insertion end of the nozzle body than a portion of the outlet orifice closest to the insertion end, of the nozzle body.
