The application discloses a multi-chamber, multi-formulation fluid delivery system, comprising a multi-chamber applicator in fluid communication with multi-chamber packaging. Applicators according to the instant disclosure have reduced squeeze-strength requirements, and are useful for dispensing fluids, including medicaments, to animals, including livestock animals. The multi-chamber packaging provides separate storage for formulations containing incompatible active ingredients, and is suitable for use with the multi-chamber applicator. The application also discloses methods for using the system to simultaneously deliver multiple active ingredients, at least some of which are not suitable for co-formulation, thus reducing the time, economic burden and animal stress involved with applying multiple, separate formulations to animals.

1. A multi-chamber, multi-liquid delivery system comprising: an applicator having an outlet for delivering at least two liquids; anda dual chamber hose coupled to the applicator for providing parallel fluid communication from packaging, the packaging comprising at least two separate containers that prevents a liquid in each container from mixing with each other prior to entering the applicator, wherein the applicator comprises at least two barrels;each barrel comprising: an inlet that is coupled to one chamber of the dual chamber hose;a one-way valve adjacent to inlet for receiving fluid from the inlet, the one-way valve comprising means for limiting pressure within a respective barrel;wherein the pressure limiting means comprises: a first valve head and a first valve seat, wherein the first valve head can be moved from a closed position to an open position by movement of a diaphragm; anda second valve head and second valve seat, wherein the second valve head is connected to the first valve head and moves with the first valve head, such that a pressure difference across said first valve head is substantially equal to a pressure difference across said second valve head;a dispensing conduit that is in fluid communication with the one-way valve;a piston for displacing fluid through the dispensing conduit;the applicator further comprising: a mixing chamber coupled to each dispensing conduit of each barrel for mixing fluid received from each dispensing conduit to create a mixed liquid, the mixing chamber also coupled to the outlet; andan actuator coupled to each piston and for moving each piston within a respective barrel when a force is applied to the actuator, each piston when moved dispenses the mixed liquid from the mixing chamber through the outlet, whereby the applicator provides a mechanical advantage in reducing the force needed to actuate the actuator for dispensing the mixed liquid through the outlet. 2. The system of claim 1, further comprising a volume control for adjusting a fluid volume within a respective barrel received from the dual chamber hose. 3. The system of claim 2, wherein the volume control is coupled to the mixing chamber. 4. The system of claim 1, wherein the one-way valve comprises a disc. 5. The system of claim 4, wherein the disc is coupled to a spring. 6. The system of claim 5, wherein the means for limiting pressure comprises a force transfer component coupled to the spring and a ring hub, and a flexible diaphragm that engages the ring hub and a clamp ring. 7. The system of claim 1, wherein the actuator comprises a first handle coupled to a first end of each piston and a second handle coupled to the mixing chamber. 8. The system of claim 1, wherein the two containers are coupled together by a fastening device. 9. The system of claim 8, wherein the fastening device comprises at least one bracket for holding the two containers together when they are coupled to the dual chamber hose. 10. A multi-chamber, multi-formulation delivery system comprising: an applicator having an outlet for delivering at least two liquid formulations, the applicator comprises at least two barrels;each barrel comprising: an inlet;a one-way valve adjacent to inlet for receiving fluid from the inlet, the one-way valve comprising means for limiting pressure within a respective barrel;wherein the pressure limiting means comprises: a first valve head and a first valve seat, wherein the first valve head can be moved from a closed position to an open position by movement of a diaphragm; anda second valve head and second valve seat, wherein the second valve head is connected to the first valve head and moves with the first valve head, such that a pressure difference across said first valve head is substantially equal to a pressure difference across said second valve head;a dispensing conduit that is in fluid communication with the one-way valve;a piston for displacing fluid through the dispensing conduit;the applicator further comprising: a mixing chamber coupled to each dispensing conduit of each barrel for mixing fluid received from each dispensing conduit to create a mixed formulation liquid, the mixing chamber also coupled to the outlet; andan actuator coupled to each piston and for moving each piston within a respective barrel when a force is applied to the actuator, each piston when moved dispenses the mixed formulation liquid from the mixing chamber through the outlet, whereby the applicator provides a mechanical advantage in reducing the force needed to actuate the actuator for dispensing the mixed formulation liquid through the outlet. 11. The system of claim 10, further comprising a dual chamber hose coupled to the applicator for providing parallel fluid communication from packaging. 12. The system of claim 10, wherein the packaging comprises at least two separate containers, each container comprising a different liquid formulation. 13. The system of claim 12, wherein the two containers are coupled together by a fastening device. 14. The system of claim 13, wherein the fastening device comprises at least one bracket for holding the two containers together when they are coupled to the dual chamber hose. 15. The system of claim 10, further comprising a volume control for adjusting a fluid volume within a respective barrel received from the dual chamber hose. 16. The system of claim 14, wherein the volume control is coupled to the mixing chamber. 17. The system of claim 10, wherein the one-way valve comprises a disc. 18. The system of claim 17, wherein the disc is coupled to a spring. 19. The system of claim 18, wherein the means for limiting pressure comprises a force transfer component coupled to the spring and a ring hub, and a flexible diaphragm that engages the ring hub and a clamp ring. 20. The system of claim 10, wherein the actuator comprises a first handle coupled to a first end of each piston and a second handle coupled to the mixing chamber. 21. A multi-chamber, multi-formulation delivery system comprising: an applicator having an outlet for delivering at least two liquid formulations, the applicator comprises at least two barrels;each barrel comprising: an inlet;a one-way valve adjacent to inlet for receiving fluid from the inlet, the one-way valve comprising a pressure relief device for limiting pressure within a respective barrel;wherein the pressure limiting device comprises: a first valve head and a first valve seat, wherein the first valve head can be moved from a closed position to an open position by movement of a diaphragm; anda second valve head and second valve seat, wherein the second valve head is connected to the first valve head and moves with the first valve head, such that a pressure difference across said first valve head is substantially equal to a pressure difference across said second valve head;a dispensing conduit that is in fluid communication with the one-way valve;a piston for displacing fluid through the dispensing conduit;the applicator further comprising: a mixing chamber coupled to each dispensing conduit of each barrel for mixing fluid received from each dispensing conduit to create a mixed formulation liquid, the mixing chamber also coupled to the outlet; andan actuator coupled to each piston and for moving each piston within a respective barrel when a force is applied to the actuator, each piston when moved dispenses the mixed formulation liquid from the mixing chamber through the outlet, whereby the applicator provides a mechanical advantage in reducing the force needed to actuate the actuator for dispensing the mixed formulation liquid through the outlet. 22.
