Abstract

A gel dispensing hair brush having a plurality of hollow bristles tapering from a head of the brush to a free end at a tip of the bristle for dispensing a gel from within a storage reservoir of the brush. The bellows or storage device from which the gel is dispensed is maintained between four guide ramps located surrounding the bellows. Each opposed set of guide ramps intersects at an obtuse angle so as to guide the sides of the bellows upwardly as the bellows is compressed by a compression plate. Compression of the bellows is achieved by rotation of a thumb wheel extending through the handle of the brush. The recesses and projections of the thumb wheel interengage with complementary shaped recesses and projections found on a toothed side of an indexing bar. On an opposite side of the indexing bar, opposite to the thumb wheel, is a smooth guide roller for maintaining an accurate movement of the indexing bar between the thumb wheel and guide roller. A dispensing plate is movable under the head of the brush. The dispensing plate includes holes approximately 2 mm in diameter, equal to approximately 2/3 of the diameter of the open base of the dispensing bristles. The diameter of the open base of the dispensing bristles is 3 to 4 mm, and preferably 3 mm.

Claims

1. A hair brush comprising:

a handle,

a head,

a plurality of hollow bristles extending from one side of said head,

a gel reservoir located in said head,

a dispensing plate slidably mounted between said gel reservoir and said hollow bristles, said dispensing plate including a plurality of apertures for allowing gel from said gel reservoir to pass into said hollow bristles when said apertures are aligned with said hollow bristles,

a slide switch located on one side of said handle and on a same side of the brush as the bristles, said slide switch moving said dispensing plate,

a compression device for forcing gel from said gel reservoir into said hollow bristles through said dispensing plate, and

a thumb wheel operable independently of said dispensing plate and located on said one side of said handle adjacent to said slide switch for actuating said compression device.

2. A hair brush as claimed in claim 1, wherein a slide switch in said handle is connected to said dispensing plate for moving said dispensing plate.

3. A hair brush as claimed in claim 1, wherein said hollow bristles taper inwardly from a base to a tip located at a free end of said hollow bristles.

4. A hair brush as claimed in claim 1, wherein said gel reservoir is located between guide plates for guiding movement of said gel reservoir as said gel reservoir is compressed.

5. A hair brush as claimed in claim 4, wherein four guide plates guide said gel reservoir.

6. A hair brush as claimed in claim 1, wherein said compression device includes a compression plate secured to said gel reservoir.

7. A hair brush as claimed in claim 6, wherein a wheel in said handle is rotated to move said compression plate.

8. A hair brush as claimed in claim 7, wherein an indexing bar is connected between said compression plate and said wheel.

9. A hair brush as claimed in claim 8, wherein said indexing bar includes a plurality of projections and recesses for engagement by a plurality of projections and recesses of said wheel.

10. A hair brush as claimed in claim 9, wherein said indexing bar is slidably mounted between upper and lower guide plates.

11. A hair brush for dispensing hair gel, said hair brush comprising:

a hollow body including a handle and a head,

a plurality of hollow bristles inter-dispersed between a plurality of rigid bristles projecting from an upper surface of said head,

a gel reservoir located in said head,

a dispensing plate slidably mounted between said gel reservoir and said hollow bristles, said dispensing plate including a plurality of apertures for allowing gel from said gel reservoir to pass into said hollow bristles when said apertures are aligned with said hollow bristles,

a compression device for forcing gel from said gel reservoir into said hollow bristles through said dispensing plate, said compression device including a compression plate secured to said gel reservoir at one end of an indexing bar and an opposite end of said indexing bar extending to said handle and engaging a thumb wheel rotatably mounted in said handle, said thumb wheel and said opposite end of said indexing bar including complementary shaped projections and recesses for moving said indexing bar by rotation of said thumb wheel, and

a slide switch located in said handle for movement of said dispensing plate so as to align said apertures of said dispensing plate with openings located at a base of said hollow bristles and allowing gel to be dispensed from said gel reservoir into said base opening,of said hollow bristles and eventually to be forced from a free tip end of said hollow bristles.

12. A hair brush as claimed in claim 11, wherein a ratio of a diameter of said free tip end of said hollow bristles to a diameter of said base opening of said hollow bristles is in the range of 1:

1 to 1;

4.

13. A hair brush as claimed in claim 12, wherein the ratio in 1:

3.

14. A hair brush as claimed in claim 11, wherein a refill passageway extends between a sidewall of said body and said gel reservoir.

15. A hair brush as claimed in claim 14, wherein said gel reservoir is a hollow bellows.

16. A hair brush as claimed in claim 15, wherein said bellows is collapsible by compression of risers and landings formed in an outer surface of said bellows.

17. A hair brush as claimed in claim 11, wherein said indexing bar is slidably mounted between upper and lower guide plates.

18. A hair brush as claimed in claim 11, wherein said one end of said indexing bar extends around a guide wheel.

19. A hair brush as claimed in claim 11, wherein said gel reservoir is located between guide plates for guiding movement of said gel reservoir as said gel reservoir is compressed.

20. A hair brush as claimed in claim 19, wherein four guide plates guide said gel reservoir.
