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.
