SHEEF 2 [IF 2' VARIABLE DEPTH HAIR COLORING APPLICATOR BACKGROUND OF THE INVENTION This invention relates generally to a comb dispenser utilized for coloring or dyeing human hair, and'in particular to a dispenser having a depth varying adjustment which allows for the distribution of dye into the hair at various hair lengths beginning from the roots to insure uniform coloring of the hair. In the past, various combs have been shown which provide for distribution of various hair preparations for treating the hair and scalp. However, the teeth of the comb were fixed and adjustment to various hair depths from the roots out toward the hair end had to be haphazardly accomplished because of the fixed tooth lengths. The Applicant's invention overcomes these disadvantages by providing a comb having a plurality of outer teeth which are tube shaped and a plurality of inner tubes which are adjustable within the ,outer tubes along the longitudinal axis of the tubes to provide for dispensing hair dye or the like to provide coloring throughout the human headof hair.

BRIEF DESCRIPTION OF THE INVENTION A comb applicator comprising a liquid storage compartment, a support means, plurality of elongated hollow teeth connected to said support means, each of said teeth having longitudinally disposed slots on the end opposite the connected end, a plurality of inner tubes, each of said tubes connected in a different respective tooth within and concentrically disposed and moveable ,therein,-a support passage moveably coupled to each of said inner tubes and said support, and a conduit moveably coupled and in fluid communication into said fluid passage at said other end whereby fluid in said storage container may be ejected from the end of said teeth and the fluid flow ejectment may be regulated by moving the inner tube longitudinally with respect to said outer teeth.

In operation, a dye or coloring material is placed in said container that is to be utilized on a human head of hair, or the like. The operator then adjusts the relative position of the inner tube free end portion which is positioned somewhere in and adjacent to the slotted end portion of the outer teeth. The deep root area may be utilized as a starting point at which time fluid is then ejected in the root areas. When this is completed the inner tubes are moved away from the end of the outer teeth so that fluid will be ejected at a different depth of hair relative to the scalp and the operation is continued. The adjustment is moved until the entire hair portion is uniformly dyed or colored.

Additional fluid ejecting means, such as air pressure or a valve release may be added to control or stop the flow when desired.

It is an object of this invention to provide an improved hair dyeing dispenser for home or commercial use which allows the operator to manually control the depthof flow penetration to more-easily and uniformly distribute dye throughout the hair.

And still yet another object of this invention is to provide a dispensing means having improved depth of distribution.

And yet another object of this invention is to provide a comb applicator with improved distribution characteristics. I

In accordance with these and other objects which will be apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a side, elevational view of Applicants invention.

FIG. 2 shows a bottom, plan view of Applicant's invention.

FIG. 3A shows a front elevational view of one of the PREFERRED EMBODIMENT OF THE INVENTION Referring now. to the drawings and in particular FIG.

l, Applic'ants dispenser is shown generally at 10 comprising a storage container 12, cylindrical in shape and which may be constructed of resilient material, having a neck end portion 16 which is threadably coupled to a cap 14. The neck is in fluid communication at the end of the container 12. The cap has a conduit 28 connected therethrough at its top portion, the conduit being in fluid communication with support conduit 34 which provides fluid flow into support passage 26 moveably mounted in support frame 18 which is generally rectangular in shape. Connected along one side of fluid passage 26 are a plurality of small flexible tubes 22 which are disposed concentrically within a plurality of' teeth 20 which are connected to the. top outside of support frame 18.

FIG. 2 shows abottom view of the dispenser showing the teeth 20 having elongated slots 24 disposed at their free end with the end portion of tube 22 shown therethrough. A valve means 32 may be provided for regulating the flow of liquid from the device which may include a pressurizing means to provide air pressure to force the liquid from the container 12.

FIG. 3A shows an end viewof the tooth 20 having a slotted lower portion 24 with the inner tube 22 disposed therein.

FIG. 3B and FIG. 3C show close-up views of the end slot portion. The importance of the end slot portion is that by adjusting the longitudinal relative position of the inner tubes with respect to the outer teeth and the end ejecting opening of the inner tube with respect to the teeth slots, the liquid flow to the hair may be. adjusted as to depth with the end of the teeth positioned adjacent the end of the scalp. The teeth may be slightly 7 bent downward as shown in FIG.. 1 to make it easier to work with to accommodate the curvature of the human head.

In operation, the cap is removed from the container 12 and the dye or coloring is placed within the container. The tube is then rotatably screwed onto the neck forming a sealed dispenser. The supporting passage which allows fluid to be transferred from conduit 34 into the inner tubes 22 slides relative to frame 18 in a longitudinal direction back and forth and is adjusted for the initial dyeing operation near the roots. After the root portion of the hair has been dyed, the passage is moved toward the cap to allow the fluid to be ejected at a higher region of the hair thus insuring uniform distribution. The teeth act to separate the hairs into groups for the dyeing operation. The procedure is repeated until the entire head has been dyed uniformly.

FIG. 4 shows an additional attachment which may be utilized with Applicants invention to insure further uniform distribution of the hair coloring to be added to the human head. A comb attachment having a comb base 36 and a plurality of solid teeth 38 which are curved to have substantially the curvature of the fluid admitting tubes as shown in FIG. 1 of Applicants invention has a coupling means 40 which may be a resilient-type clip which clips about each end exterior rod so that the teeth of the comb 38 will provide additional separation and alignment of the hairs while the dispenser is in operation. The attachment may be such that the comb teeth could be provided from the top or the bottom or together on the'top and bottom of the dispensing tubes to provide additional alignment as the dispenser is being utilized with the human scalp. This would further insure proper distribution of the fluid being applied to the hairs.

The instant invention has been shown and described herein in what is considered to be the most preferred and practical embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.

What I claim is:

l. A comb dispenser for dyeing human hair uniformly comprising:

a fluid receiving container means for receiving dye;

a plurality of elongated hollow teeth, each of said teeth having a slotted free end portion longitudinally disposed;

a plurality of flexible tubes, each of said tubes disposed in a different respective tooth and coupled moveably therein;

a support means connected to said teeth, said inner tubes, and said container;

means coupled to said inner tubes and said support means for moveably adjusting the longitudinal position of said tubes within said teeth; and

conduit means connecting said inner tubes and in fluid communication with said container means.

2. A dispenser, as in claim 1, wherein said inner tube adjusting means includes:

a manifold moveably coupled within said support means and in fluid communication with said flexible tubes and said conduit means.
