Abstract
A fluid dispensing wand having a fluid reservoir removably attachable to a wand for applying a fluid such as hair oil, coloring, lightener, highlight, detangler, or conditioner to the hair. A fluid delivery means disperses fluid from the reservoir throughout the wand to effect even distribution of the fluid throughout the hair. The fluid delivery means comprises a series of conduits and/or a porous material. Teeth and/or fins are formed upon the wand such that the wand may be moved through the hair in a comb-like fashion to effect transfer of the fluid thereto. An absorbent covering may optionally be formed over the wand intermediate the teeth or fins to further enhance the even distribution of fluid. A plug or seal preferably closes the reservoir, thus providing a fluid cartridge. Thus, various cartridges may be installed upon the wand to effect application of various desired fluids to the hair. Several valve arrangements for selectively facilitating fluid communication between the reservoir and wand are disclosed. In additional configurations, fluid is pumped, via a plunger or bulb, from the reservoir to the wand.
