Abstract
A spray bottle combination for dispensing fluids from multiple containers, while simultaneously and instantaneously venting the fluid containers. The combination includes at least two fluid containers, a sprayer mechanism, including a sprayer actuator, for pumping fluid from the containers to dispense the fluid, a manifold and a fluid transfer mechanism. One end of the manifold is connected to an outlet end of each of the fluid containers. The manifold provides at least one fluid discharge opening and at least one vent opening for each container. The fluid transfer mechanism provides fluid communication between the fluid discharge openings of the manifold and the sprayer mechanism. The fluid transfer mechanism includes a valve arrangement, engageable with another end of the manifold, for simultaneously opening and closing the fluid discharge openings and air passage to and from the vent openings of the manifold upon a corresponding pumping actuation and deactuation of the sprayer actuator.
