Abstract

The system includes a hair color packet assembly having several individual hair color packets and one developer packet, each packet having a pump for delivering selected amounts of material to a mixing assembly. A control assembly operable in response to a user'"'"'s input controls each of the pumps to deliver selected amounts of color material and developer material to a mixing assembly which mixes the colors and the developer and delivers it to a brushhead/distributor, which has openings through which the selected hair color formulation is delivered. The brushhead/distributor is mountable in a handle having a motor which drives the brushhead/distributor in a linear oscillating manner.

Claims

1. A hair coloring system, comprising:

a hair color packet assembly having at least two coloring material chambers each containing different coloring dye material, and one or zero developer material chamber containing developer material;

each of the coloring material chambers and the one or zero developer material chamber having a pump operatively coupled thereto for dispensing the coloring dye material or the developer material associated therewith;

each pump having an output line therefrom for receiving the coloring dye materials and the developer material dispensed by the pumps associated therewith;

the output lines merging into a mixer line containing a mixing element which receives and mixes the coloring dye materials or the coloring dye materials and the developer material dispensed by the pumps;

a control assembly including a microprocessor operable to control each of the pumps separately to dispense each of the coloring dye materials and developer material over a range of flow rates, wherein the microprocessor has control information stored therein for producing colors and responds to a user'"'"'s input of a selected color to control the pumps to dispense appropriate combinations of one or more of the hair coloring dye materials and developer material to produce the selected color, following mixing;

a brushhead connected to the mixer line via a connecting line; and

a handle extending from the brushhead

wherein the hair color packet assembly, the pumps, the output lines, the mixer line, the connecting line and the control assembly are external to the handle and the brushhead.

2. The system of claim 1, wherein the brushhead includes a plurality of tines, one or more of which include openings through which the mixed coloring dye materials or coloring dye materials and developer material move, the brushhead further including bristles positioned intermediate of successive tines.

3. The system of claim 1, including more than one brushhead, for use in coloring different parts of the user'"'"'s hair.

4. The system of claim 1, wherein the user input is in the form of information provided on cards and the control assembly includes an optical assembly for reading the card information.

5. The system of claim 1, wherein the user input is in the form of a magnetic strip reader and wherein the control assembly includes a reader for reading the magnetic strip information.

6. The system of claim 1, wherein the user input is in the form of an RFID tag and the control system includes a reader for reading the RFID information.

7. The system of claim 1, wherein the user input is in the form of a wireless command.

8. The system of claim 1, wherein the at least two coloring material chambers comprise three to five different coloring material chambers and the one or zero developer material chamber comprises one developer material chamber.

9. The system of claim 1, wherein the pumps are controlled to produce a formulation flow rate in the connecting line of approximately 1.25 ml/second.

10. The system of claim 1, wherein the one or zero developer material chamber comprises one developer material chamber and a combined flow rate of the coloring dye materials is approximately equal to a flow rate of the developer material.

11. The system of claim 2, wherein the connecting line comprises a plurality of connecting lines extending from the mixer line to the brushhead, arranged to provide different colors to different tines of the brushhead.

12. A hair coloring system, comprising:

a hair color packet assembly having at least two coloring material chambers each containing coloring dye material, and one or zero developer material chamber containing developer material;

each of the coloring material chambers and the one or zero developer material chamber having a pump operatively coupled thereto for dispensing the coloring dye materials or the developer material associated therewith;

each pump having an output line therefrom for receiving the coloring dye materials and the developer material dispensed by the pumps associated therewith;

the output lines merging into a mixer line containing a mixing element which receives and mixes the coloring dye materials or the coloring dye materials and the developer material dispensed by the pumps;

a control assembly including a microprocessor operable to control each of the pumps separately to dispense each of the coloring dye materials and developer material over a range of flow rates, wherein the microprocessor has control information stored therein for producing colors and responds to a user'"'"'s input of a selected color to control the pumps to dispense appropriate combinations of one or more of the hair coloring dye materials and developer material to produce the selected color, following mixing;

a brushhead connected to the mixer line via a connecting line;

a handle extending from the brushhead, wherein the brushhead is adapted to move in the handle; and

a motor housed in the handle and operatively coupled to the brushhead to move the brushhead back and forth in a linear movement oscillation;

wherein the hair color packet assembly, the pumps, the output lines, the mixing line, the connecting line and the control assembly are external to the handle and the brushhead.

13. The system of claim 12, wherein the brushhead includes a plurality of tines, one or more of which include openings through which the mixed coloring dye materials or coloring dye materials and developer material move, the brushhead further including bristles positioned intermediate of successive tines.

14. The system of claim 12, wherein the user input is in the form of information provided on cards and the control assembly includes an optical assembly for reading the card information.

15. The system of claim 12, wherein the user input is in the form of a magnetic strip reader and wherein the control means includes a reader for reading the magnetic strip information.

16. The system of claim 12, wherein the user input is in the form of an RFID tag and the control system includes a reader for reading the RFID information.

17. The system of claim 12, wherein the user input is in the form of a wireless command.

18. The system of claim 12, wherein the hair color packet assembly, the pumps for the coloring material and developer material, the control assembly and the mixing assembly are separable from the brushhead and disposable.

19. The system of claim 13, wherein the linear movement is greater than one-half the distance between successive tines and less than one and one-half times the distance between successive tines.

20. The system of claim 13, wherein the at least two coloring material chambers comprise three to five different coloring material chambers and the one or zero developer material chamber comprises one developer material chamber.

21. The system of claim 13, wherein the pumps are controlled to produce a formulation flow rate in the connecting line in the range of 10 cc/min-300 cc/min.

22. The system of claim 13, wherein the one or zero developer material chamber comprises one developer material chamber and a combined flow rate of the coloring dye materials is approximately equal to a flow rate of the developer material.

23. The system of claim 13, including wherein the connecting line comprises a plurality of connecting lines extending from the mixer line and connected to the brushhead and are arranged to provide different colors to different tines of the brushhead.
