Abstract

A dispensing system having a treatment cartridge utilizing linear translation of the treatment cartridge within the manifold to actuate a valve to dispense a fluid. To dispense the fluid, a person pushes their glass or other container against a dispensing lever that translates the treatment cartridge within the manifold causing a cam surface on the filter's circumferential exterior to actuate a valve sending the fluid from the valve though the treatment cartridge and out a dispensing orifice in the treatment cartridge into the glass.

First claim

What is claimed is:

1. A method of dispensing a fluid comprising:
positioning a translating treatment cartridge having a housing with an inlet orifice, a dispensing orifice, and a treatment media within the housing into a manifold; the manifold having a cartridge bore surrounding a central axis of the manifold and a fluid inlet; and
moving the translating treatment cartridge linearly along the central axis from a first position to a dispensing position causing the fluid to flow from the fluid inlet, though the inlet orifice, through the translating treatment cartridge such that the fluid entering the inlet orifice passes through the treatment media and out the dispensing orifice; and
wherein the fluid inlet comprises an inlet bore, a valve seat located in the inlet bore, and a spring biased poppet valve located within the inlet bore; the translating treatment cartridge comprises a cam surface located on the housing; and wherein the spring biased poppet valve is seated against the valve seat in the first position, and the cam surface opens the spring biased poppet valve in the dispensing position.

2. The method of claim 1 comprising moving the translating treatment cartridge from the dispensing position to the first position stopping the flow of fluid from the dispensing orifice.

3. The method of claim 1 comprising biasing the translating treatment cartridge to return to the first position.

4. The method of claim 1 wherein the positioning comprises inserting an end of the translating treatment cartridge through the cartridge bore and engaging a dispensing lever with a dispensing lever engagement feature located on the translating treatment cartridge.

5. The method of claim 4 wherein engaging the dispensing lever comprises rotating the translating treatment cartridge about the central axis.

6. The method of claim 5 comprising passing a portion of the dispensing lever engagement feature though a slotted portion of the dispensing lever prior to rotating the translating treatment cartridge.

7. The method of claim 5 wherein the rotation rotates the translating treatment cartridge within the cartridge bore.

8. The method of claim 5 wherein the rotation rotates the cartridge bore and manifold about the central axis.

9. The method of claim 4 comprising passing the end of the translating treatment cartridge through a cartridge bore end of the dispensing lever.

10. The method of claim 4 comprising moving the dispensing lever causing the translating treatment cartridge to move linearly along the central axis.

11. The method of claim 10 wherein the moving comprises pushing on the dispensing lever with a glass and dispensing the fluid from the dispensing orifice into the glass.

12. The method of claim 1 comprising retracting the dispensing orifice into the cartridge bore when the translating treatment cartridge is in the first position.

13. The method of claim 12 comprising aligning the dispensing orifice with an auxiliary port in the manifold when the translating treatment cartridge is in the first position.

14. The method of claim 13 comprising activating a solenoid valve causing the fluid to flow from a second fluid inlet in the manifold, through the translating treatment cartridge, out the dispensing orifice, and into the auxiliary port.

15. The method of claim 1 wherein the translating treatment cartridge comprises:
a first dispensing orifice and a second dispensing orifice; and
wherein moving the translating treatment cartridge linearly along the central axis comprises:
moving from the first position in a first direction to a first dispensing position causes the fluid to flow from the fluid inlet, though the inlet orifice, through the translating treatment cartridge such that the fluid entering the inlet orifice passes through the treatment media and out the first dispensing orifice; and
moving from the first position in a second direction to a second dispensing position causes the fluid to flow from the fluid inlet, though the inlet orifice, through the translating treatment cartridge such that the fluid entering the inlet orifice passes through the treatment media and out the second dispensing orifice.

16. The method of claim 15 wherein the positioning comprises inserting an end of the translating treatment cartridge through the cartridge bore and engaging a dispensing lever with a dispensing lever engagement feature located on the translating treatment cartridge.

17. The method of claim 16 wherein pushing on the dispensing lever causes the fluid to be dispensed from the first dispensing orifice.

18. The method of claim 16 wherein pulling on the dispensing lever causes the fluid to be dispensed from the second dispensing orifice.

19. The method of claim 15 comprising biasing the translating treatment cartridge to return to the first position.

20. The method of claim 1 wherein moving the translating treatment cartridge linearly along the central axis from the first position towards the dispensing position varies the fluid flow from the dispensing orifice, and the fluid flow increases the farther the translating treatment cartridge is moved away from the first position until a maximum flow is obtained when the translating treatment cartridge is in the dispensing position.

21. The method of claim 1 wherein the cartridge bore has an open end for insertion and removal of the translating treatment cartridge from the manifold.

22. The method of claim 1 wherein the translating treatment cartridge comprises:
the housing having a first end, a second end, a central axis extending from the first end to the second end, a first body portion surrounding the central axis, a second body portion surrounding the central axis, and a cam surface located on the housing;
the first body portion having a larger cross-sectional area than the second body portion; and the dispensing orifice is open to the atmosphere when the translating treatment cartridge is in the dispensing position.

23. The method of claim 1 wherein the treatment media comprises a carbon block treatment media within the housing.
