## Abstract

The system includes a hair color packet assembly having one hair color packet and one developer packet and a pump assembly for moving the hair coloring material and developer material to a mixing assembly which mixes the color 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

### Claim 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;
wherein each of the coloring material chambers and the one or zero developer material chamber includes 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 material 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 hair colors and responds to a user's input of a selected hair color to control the pumps to dispense appropriate combinations of one or more of the hair coloring dye materials and developer material to produce a hair formulation for the selected hair color, following mixing;
a brushhead connected to the mixing line via a connecting line wherein the brushhead includes a plurality of tines, one or more of which include openings through which the mixed dye materials and developer material move, the brushhead further including bristles which in use extend just past lower ends of the tines, contacting the scalp and the tines are positioned slightly above the scalp to allow the hair formulation to escape therefrom;
a handle extending from the brushhead; and
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.

### Claim 2 (depends on 1)

The system of claim 1, wherein the bristles are positioned intermediate of the tines.

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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.

### Claim 6 (depends on 1)

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.

### Claim 7 (depends on 1)

The system of claim 1, 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.

### Claim 8

A single use hair color consumable assembly for use with 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 dye materiel chambers and the one or zero developer material chamber having a pump operatively coupled thereto for dispensing the coloring dye materials or the developer materials associated therewith, each pump having an output line therefrom for receiving the coloring dye materials and 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 microprocessor operably coupled to each of the pumps, wherein the microprocessor includes 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 coloring dye material and the developer material to produce a hair formulation for the selected color, and wherein the pumps are responsive to a control signal from the microprocessor for variably controlling the flow rate of the coloring dye materials and developer material to produce the hair formulation; and
a brushhead member connected to the mixing assembly by a connecting line, wherein the brushhead includes a plurality of tines, one or more of which include openings through which the mixed coloring dye materials or developer materials move, the brushhead further including bristles which in use extend just past the lower end of the tines, contacting the scalp, and the tines are positioned slightly above the scalp to allow the hair formulation to escape therefrom, wherein the hair packet assembly, the pumps, the output lines and the mixer line are separable from the brushhead and disposable.

### Claim 9 (depends on 8)

The system of claim 8, wherein the bristles are positioned intermediate of the tines.

### Claim 10

A hair coloring system, comprising;
a hair color packet assembly having at least two coloring material chambers each containing dye material and one or zero developer material chambers containing developer material;
wherein each of the coloring material chambers and the one or zero developer material chamber includes a pump operatively coupled thereto for dispensing the coloring dye material or the developer material associated therewith, each pump having an outlet line for receiving the coloring dye material 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 includes 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 a hair formulation for the selected color, following mixing;
a brushhead connected to the mixer line via a connecting line, wherein the brushhead assembly includes a plurality of tines, one or more of which include openings through which the mixed dye materials and the developer material move, the brushhead further including bristles which extend just past the lower ends of the tines, contacting the scalp, wherein the tines are positioned slightly above the scalp allowing the hair formulation to escape therefrom;
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 connected 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.

### Claim 11 (depends on 10)

The system of claim 10, wherein the bristles are positioned intermediate of the tines.

### Claim 12 (depends on 10)

The system of claim 10, wherein the linear movement of the tines is greater than ½ the distance between successive tines and no greater than 1½ times the distance between successive tines.

### Claim 13 (depends on 10)
