Abstract:
A squeeze bottle sprayer which is actuated upon squeezing the bottle to force liquid up a dip tube and emit a liquid-air spray through a spray orifice, comprising:a squeezable bottle containing a volume of liquid and air above the liquid;a dip tube extending into said volume of liquid;a sprayer body defining a valve receptacle therein, having a valve, a tapered section defining a mixing chamber therein, the tapered section being tapered in a direction toward a spray orifice which is defined through the valve at a terminal point of the tapered section; the valve defining a liquid passageway there through connecting the dip tube with the mixing chamber in an open position of the valve, at least a portion of the liquid passageway being disposed in a direction toward the spray orifice and having a longitudinal axis aligned through said portion and said spray orifice, the valve defining a fluid control notch and an air control notch, the fluid control notch controlling the amount of communication between the dip tube and the product passageway, the air control notch controlling the amount of communication between the interior of the bottle and an air passageway, the valve and the liquid passageway being selectively rotatable about said longitudinal axis between a closed position wherein the mixing chamber is disconnected from the dip tube and an open position wherein the mixing chamber is connected to the dip tube;the air passageway, concentrically disposed around said portion of the liquid passageway, the air passageway connecting an interior of the bottle containing said volume of air with the mixing chamber and the air passageway communicating with the mixing chamber at a location directly opposite to the tapered section of the sprayer body; wherein the mixing chamber is disconnected from the interior of the bottle in a closed portion of the valve and the air control notch controls the amount of communication between the interior of the bottle and the air passageway,whereby upon actuation of the squeeze bottle sprayer a stream of air from the air passageway will be deflected by the tapered section of the sprayer body to converge and impinge upon a core stream of liquid from the liquid passageway in the mixing chamber to atomize the stream of liquid.
