Abstract
A device for mixing and dispensing fluid is disclosed and comprises first and second containers each having a valve for dispensing fluid. The valve is normally biased to a closed position and operable against said bias to an open position. Piston and cylinder elements define a chamber for receiving the fluids. The piston element is movable in response to dispensing of fluid into said chamber. The piston element is operably connected to the valves and exerts a force on the valves to maintain them in an open position. The mixed fluids in the chamber are thereafter dispensed through a handpiece.
