Abstract

A formula delivery appliance can be used for treatment of the hair and scalp, such as an appliance used to color hair. The appliance may include a consumable assembly incorporating various components of the hair and scalp treatment appliance, a portion of which may be consumed and then replaced by a user. In this regard, the consumable assembly may include one or more formulation delivery packets, nozzles, manifold chambers, distribution protrusions, and the like. The hair treatment appliance may also include a rotatable coupling having a driven gear and a drive gear, where the driven gear may selectively engage the drive gear. In another aspect, the hair treatment appliance may also include a fluid container to retain a volume of formulation for delivery to the appliance.

First claim

The invention claimed is:

1. A hair coloring appliance having a formulation delivery system, the hair coloring appliance comprising:
a handle;
a reciprocating assembly comprising a plurality of outlet nozzles;
a static mixer; and
a consumable assembly removably couplable to the handle, the consumable assembly having a first fluid container configured to retain a first formulation, and a second fluid container configured to retain a second formulation, wherein upon coupling of the consumable assembly to the handle, the first fluid container and the second fluid container are fluidically coupled to the static mixer and to the plurality of outlet nozzles.

2. The hair coloring appliance of claim 1 , wherein the reciprocating assembly includes a reciprocating wheel, wherein the reciprocating wheel is operably coupled to a motor.

3. The hair coloring appliance of claim 2 , wherein the motor is operably coupled to a pump configured to pump the first formulation and the second formulation through the static mixer.

4. The hair coloring appliance of claim 1 , wherein the static mixer is a helical static mixer fluidically connected to a manifold chamber configured to distribute a mixture of the first formulation and the second formulation to the plurality of outlet nozzles.

5. The hair coloring appliance of claim 4 , wherein the reciprocating assembly includes a reciprocating wheel, wherein the reciprocating wheel is operably coupled to a motor.

6. The hair coloring appliance of claim 5 , wherein the motor is operably coupled to a pump configured to pump the first formulation and the second formulation through the static mixer.

7. The hair coloring appliance of claim 1 , wherein the static mixer is fluidically coupled to a pump configured to pump the first formulation and the second formulation through the static mixer.

8. The hair coloring appliance of claim 1 , further comprising the first formulation, wherein the first formulation is selected from the group consisting of permanent hair dye, semi-permanent hair dye, developer, conditioner, hair growth treatment, ROGAINE®, hair protein treatment, fluid hair treatment, and fluid scalp treatment.

9. The hair coloring appliance of claim 1 , wherein the first fluid container includes an orifice configured to interface with an inlet member to allow flow of the first formulation from the first fluid container to a fluid receiving chamber.

10. The hair coloring appliance of claim 9 , wherein the first fluid container further comprises a valve configured to regulate the flow of the first formulation out of the orifice.

11. The hair coloring appliance of claim 10 , wherein the first fluid container further comprises a membrane covering the orifice, wherein the membrane is configured to allow outgassing of the first formulation.

12. The hair coloring appliance of claim 1 , wherein the first fluid container includes a flexible wall that at least partially collapses as the first formulation flows out of the first fluid container.

13. The hair coloring appliance of claim 12 , wherein the first fluid container includes a protrusion extending through a length of the first fluid container, the protrusion being configured to create a flow path for the first formulation as the flexible wall at least partially collapses.
