ABSTRACT:
Dispensing nozzles having a spout for dispensing a fluid are provided. The spout comprises a first tube for engaging the dispensing nozzle and having an outer surface, a proximal end, a distal end, and a first passage interconnecting the proximal and distal ends. A second tube is disposed within the first passage of the first tube and communicates with a first opening on the outer surface of the first tube, the first opening being located adjacent the distal end. A valve seat is disposed at least partially within the first passage at the proximal end of the first tube and has a second passage disposed therein. A plug is disposed within the first passage between the valve seat and the distal end and has a third passage extending therethrough. A valve is disposed between the plug and the valve seat for sealingly engaging the valve seat, the valve being biased into engagement with the valve seat. The second tube engages the plug and communicates with a fourth passage disposed within the plug, the first tube having a second opening disposed on the outer surface adjacent the proximal end of the first tube which communicates with the fourth passage. In addition, the second and third passages are in fluid communication with the distal end during use.
