The diving nozzle of claim 1, wherein the fluid controlled actuator is a pneumatic actuator. 3. The diving nozzle of claim 1, wherein the first material is the purging gas and the second material is a liquid product. 4. The diving nozzle of claim 3, wherein the second tube is at least partially received within the first tube and the second tube extends coaxially with the first tube. 5. The diving nozzle of claim 4, wherein the second tube is moveable with respect to the first tube so as to displace the second tube between an extended position and a retracted position, in the retracted position a distal end of the second tube is received within a distal end of the first tube to close the first outlet, and in the extended position the second tube is displaced relative to the first tube to space the distal end of the second tube from the distal end of the first tube to open the first outlet of the first tube. 6. The diving nozzle of claim 5, wherein the first material is prevented from being discharged when the second tube is in the retracted position. 7. The diving nozzle of claim 6, wherein the distal end of the second tube is formed having a stopper adjacent the distal end of the second tube, the stopper seals the first outlet when the second tube is in the retracted position. 8. The diving nozzle of claim 7, wherein the stopper includes a base portion having an outer diameter corresponding to an inner diameter of the distal end of the first tube. 9. The diving nozzle of claim 8, wherein the stopper has a generally frustoconical shaped portion positioned above the base portion, and when the second tube in in the extended position and the first material dispensed from the first outlet, the first material contacts the frustoconical shaped portion of the stopper to diffuse the first material into the package. 10. The diving nozzle of claim 9 further comprising a vertical displacement mechanism that vertically displaces the diving nozzle between a raised position and a lowered position, in the raised position the distal end of the first tube and the distal end of the second tube is positioned above an open end of the package, and in the lowered position a portion of the first tube and a portion of the second tube extend into the package. 11. The diving nozzle of claim 10, wherein upon displacement of the diving nozzle into, by the vertical displacement mechanism, the second material is dispensed through the second outlet, and wherein upon movement of the diving nozzle from the lowered position towards the raised position and movement of the second tube from the retracted position to the extended position the first material is dispensed through the first outlet.
