摘要：
This application discloses a multi-chamber, multi-liquid delivery system comprising: an applicator having an outlet for delivering at least two liquids and a 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 and a 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 and an 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.
