Abstract

A liquid-reservoir hairbrush that is capable of dispersing water-based and other thin and non-viscous liquids over the user'"'"'s scalp during routine hair combing or brushing. The brush bristles are preferably mounted to a flexible base. An absorbent filler is placed into a chamber of the brush body and absorbent feed rods are placed into bores of the brush bristles. The absorbent filler is preferably made from sufficiently spongy and/or springy material and covered by the flexible base. Liquid outlets (viz., nozzles) are mounted at distal ends of the brush bristles and have a roller ball liquid distribution mechanism, which functions such that the liquid will exit the nozzle when its roller ball makes a rolling contact with the user'"'"'s scalp. The absorbent feed rods interconnect the absorbent filler and the roller balls mounted within the nozzles. The chamber of the brush body can be divided into multiple, hermetically isolated sections. The brush body can have an optional filler inlet and can come with an optional liquid refilling unit which can hold a predetermine volume of the liquid. The hairbrush comes with a removable bristle lid to keep the brush bristles enclosed when the hairbrush is not in use and prevent the roller balls from drying out.

Claims

1. A liquid-reservoir hairbrush adapted for dispersing water-based solutions and other thin and non-viscous liquids over a user'"'"'s scalp during hair brushing, comprising:

(a) a brush body having a chamber;

(b) at least one absorbent filler adapted to store liquid and placed into the chamber; and

(c) a plurality of brush bristles, each having a proximal end and a distal end, not all of which are in a straight line, the brush bristles being mounted in the vicinity of their proximal ends to the brush body, wherein each brush bristle comprises;

an elongate body with bore formed therethrough,

a nozzle mounted at the distal end of each brush bristle comprising a rotatably mounted roller ball, and

at least one absorbent feed rod placed in the bore, wherein the absorbent feed rod interconnects the absorbent filler and the roller ball, and wherein the liquid will exit the nozzle when its roller ball makes rolling contact with the user'"'"'s scalp.

2. The hairbrush of claim 1, further comprising a flexible base mounted to the brush body, wherein the brush bristles are mounted to the flexible base.

3. The hairbrush of claim 1, further comprising a bristle lid to keep the brush bristles enclosed when the hairbrush is not in use and to help prevent the roller balls from drying out.

4. The hairbrush of claim 1, wherein the chamber is divided into at least two separate sections, and wherein these sections are preferably hermetically isolated from one another, and wherein the absorbent filler is placed into each section.

5. The hairbrush of claim 1, wherein the brush body has a filler inlet to permit the user to refill the absorbent filler with liquid.

6. The hairbrush of claim 5, further comprising a liquid refilling unit that is adapted to place liquid in the absorbent filler when the filler inlet is opened.

7. The hairbrush of claim 6, wherein the liquid refilling unit is pre-filled with the liquid and is adapted to engage with the brush body when the filler inlet is opened.

8. The hairbrush of claim 1, wherein the absorbent feed rods of the brush bristles extend into the brush body and into the absorbent filler and contact with the absorbent filler.

9. The hairbrush of claim 1, wherein the absorbent filler partially extends into the bores of the brush bristles and contacts with the absorbent feed rods located therein.
