The cartridge is oriented such that gravity exerts a downward force on the first fluid. The sprayer body includes a conduit for receiving a second fluid. A valve is coupled to the conduit. The valve allows the second fluid to flow through the valve, thus creating a Venturi vacuum that draws the first fluid out of the cartridge and into the valve to enable the first and second fluids to mix and form an outlet stream. An orifice meters a predetermined amount of the first fluid into the valve to achieve a predetermined ratio of the first fluid to the second fluid. The outlet stream is then dispensed from a spray nozzle. ## Claims ### Claim at position 1 1-32. (canceled) ### Claim 33 A spraying device cartridge comprising: a first liquid contained within the spraying device cartridge; a first end having a first diameter, configured to be removeably connected to a sprayer body, a second end having a second diameter and located opposite the first end wherein the second end is located in a position above the first end when the spraying device cartridge is connected to the sprayer body such that gravity exerts a downward force on the first liquid to pull the first liquid towards the first end; the first end comprising: a bore extending axially from the first end and having a diameter less than the first diameter and comprising a first set of external threads, the bore defining a fluid flow path for the first liquid, wherein a downstream direction is towards the first end and an upstream direction is towards the second end; and a check valve comprising a duckbill portion and an umbrella portion mounted in the bore, the duckbill portion comprising a path for the first liquid to flow through from the spraying device cartridge and the umbrella portion comprising an air flow path for venting of the spraying device cartridge. ### Claim 34 (depends on 33) A spraying device, comprising the spraying device cartridge of claim 33, and further comprising a sprayer body comprising: a first conduit for receiving the first liquid from the spraying device cartridge when the spraying device cartridge is coupled to the sprayer body; a second conduit for receiving a second liquid from an external source; a valve structure, comprising a first liquid passageway and a second liquid passageway, configured such that the passage of the second liquid through the valve structure creates a reduced pressure that draws the first liquid out of the spraying device cartridge and into the valve structure without the need for a dip tube; the first liquid passageway communicating with the first liquid from the first conduit and the second liquid passageway communicating with the second liquid from the second conduit, a manual actuator positioned in operative relationship with the valve structure enabling movement of the valve structure between three discrete positions comprising: a) a first position enabling the second liquid to flow through the valve structure to create a reduced pressure in the valve structure which draws the first liquid out of the spraying device cartridge and into the valve structure wherein the first and the second liquids mix to form an outlet stream which flows through the valve structure; b) a second position enabling only the second liquid to flow through the valve structure and blocking the flow of the first liquid through the valve structure, and c) a third position blocking the first and the second liquid from flowing through the valve structure; and a spray nozzle configured to discharge the outlet stream. ### Claim 35 (depends on 34) The spraying device of claim 34, further comprising: an orifice for metering a predetermined amount of the first liquid from the spraying device cartridge into the valve structure in the first position to achieve a predetermined ratio of the first liquid to the second liquid in the outlet stream. ### Claim 36 (depends on 35) The spraying device of claim 35, wherein the orifice is a variable metering disc that allows for the selection of a plurality of orifice sizes by using a selector on the sprayer body. ### Claim 37 (depends on 34) The spraying device of claim 34, wherein the spray nozzle is rotatably adjustable to provide different spray patterns. ### Claim 38 (depends on 33) The spraying device cartridge of claim 33, further comprising: a fluid filter disposed within the bore in the fluid flow path upstream of the check valve such that the fluid filter serves to filter the first liquid prior to the first liquid flowing through the check valve. ### Claim 39 (depends on 33) The spraying device cartridge of claim 33, further comprising: a secondary threaded closure being internally threaded for mounting over the first set of threads and being externally threaded for engagement with corresponding threads on the sprayer body or with corresponding threads on a closure cap, the secondary threaded closure having an aperture extending axially through a center bore that is coincident with the bore of the first end; and a metering orifice disposed in the bore, within the secondary threaded closure, located in the fluid flow path downstream of the check valve. ### Claim 40 (depends on 33) The spraying device cartridge of claim 33, further comprising: a closure cap being internally threaded for mounting over the first set of external threads; a cartridge insert configured to fit into the interior of the bore, under the closure cap; and a metering orifice, within the cartridge insert, located in the fluid flow path downstream of the check valve. ### Claim 41 (depends on 33) The spraying device cartridge of claim 33, wherein the first liquid is capable of being dispensed from the spraying device cartridge by squeezing the spraying device cartridge in an inverted position when not connected to the sprayer body.
