According to certain embodiments of the invention, a trigger sprayer may include a plunger and piston combination wherein the piston may include a flap valve or other valve system that opens upon at a certain pressure to allow fluid from within a piston chamber to pass through the plunger and out a nozzle of the trigger sprayer. According to other embodiments of the invention, an inlet valve may be seated between a container and a piston chamber such that fluid may pass the inlet valve upon return of a plunger piston combination to a non-actuated state and such that fluid is prevented from entering the container from the piston chamber when a plunger piston combination is being actuated.
