Abstract

A fluid delivery device includes an accumulator, a deformable fluid reservoir, a user-actuated valve, a fluid delivery channel and an application element. The accumulator accumulates pressure and houses the fluid reservoir. The fluid delivery channel couples the fluid reservoir on a proximal end and extends to a distal end. A user-actuated valve controls a flow rate of fluid passing through the fluid delivery channel from the fluid reservoir to the distal end in response to pressure in the accumulator being above a predetermined threshold. The application element is coupled to the distal end of the fluid delivery channel to facilitate dispersal of fluid from the fluid delivery channel.

Claims

1. A hair dye application apparatus comprising:

a deformable fluid reservoir to house hair dye;

a pressure inducing element to apply a positive pressure to the fluid reservoir;

an application element to disperse the dye into hair; and

a fluid delivery channel to deliver dye from the fluid reservoir to the application element in response to the positive pressure applied to the fluid reservoir.

2. An apparatus as in claim 1, wherein the pressure inducing element comprises a port coupled to an external pressure source.

3. An apparatus as in claim 2, wherein the external pressure source is a pressurized cartridge.

4. An apparatus as in claim 2, wherein the external pressure source is a compressor.

5. An apparatus as in claim 1, wherein the pressure inducing element comprises an internal pressure source.

6. An apparatus as in claim 5, wherein the internal pressure source is a mechanical actuator to apply a mechanical force to the fluid reservoir.

7. An apparatus as in claim 6, wherein the mechanical actuator is a plunger.

8. An apparatus as in claim 6, wherein the mechanical actuator is motorized.

9. An apparatus as in claim 6, wherein the mechanical actuator includes at least one gear.

11. An apparatus as in claim 1, further comprising a grip portion disposed between the fluid reservoir and the application element.

12. An apparatus as in claim 1, wherein the application element is a brush.

13. An apparatus as in claim 12, wherein the fluid delivery channel includes a plurality of openings dispersing dye within the brush.

14. An apparatus as in claim 1, further comprising an actuation valve disposed between the fluid reservoir and the application element to selectively control a flow rate of dye to the application element.

15. An apparatus as in claim 14, further comprising a control valve disposed within the fluid delivery channel between the fluid reservoir and the actuation valve, the control valve adapted to control direction of dye flow through the apparatus.

16. An apparatus as in claim 15, wherein the control valve is a one-way valve that allows fluid flow toward the application element and prevents fluid flow of dye into the fluid reservoir.

17. An apparatus as in claim 14, further comprising an adjustable element disposed between the fluid delivery channel and the application element to selectively control a flow rate of dye to the application element.

18. An apparatus as in claim 1, wherein the fluid reservoir is a pouch.

10. An apparatus as in clam 9, wherein the at least one gear includes a worm gear.

19. An apparatus comprising:

an accumulator to accumulate pressure;

a deformable fluid reservoir disposed within the accumulator;

a fluid delivery channel coupled to the fluid reservoir on a proximal end and extending to a distal end;

a user-actuated valve to control a flow rate of fluid passing through the fluid delivery channel from the fluid reservoir to the distal end in response to pressure in the accumulator being above a predetermined threshold; and

an application element coupled to the distal end of the fluid delivery channel for dispersing fluid from the fluid delivery channel.

20. An apparatus as in claim 19, further comprising a diaphragm disposed between the fluid reservoir and the fluid delivery channel to regulate fluid flow from the fluid reservoir.

21. An apparatus as in claim 19, further comprising a mounting member disposed between the fluid reservoir and the fluid delivery channel that includes a protrusion for insertion and coupling to an orifice in the fluid delivery channel.

22. An apparatus as in claim 19, further comprising a guiding element disposed between the distal end of the fluid delivery channel and the application element to facilitate selective fluid delivery.

23. An apparatus as in claim 19, wherein the accumulator comprises a pressurization port that is adapted to be coupled to an external pressurization source.

24. An apparatus as in claim 19, further comprising an internal pressure source coupled to the accumulator.

25. An apparatus as in claim 19, wherein the internal pressure source comprises a compressor.

26. An apparatus as in claim 19, wherein the internal pressure source comprises a mechanical actuator to apply a mechanical force to the liquid reservoir.

27. An apparatus as in claim 19, wherein the accumulator comprises a pressurization chamber and a liquid reservoir chamber separated by the user-actuated valve.
