ABSTRACT OF THE DISCLOSURE

This invention relates to hair dyeing apparatus and in particular, to wet combs and brushes for applying developers, dyes, tints, bleaches, wave-set solutions and the like to the hair.

In “touching up” or dyeing new growth of hair after it has been first bleached, it is necessary to section the hair by making a fine part from the brow to the back of the head and then deliver the dye in a fine line along the part. Before the dye has had a chance to run, it must be carefully blended usually by a thin piece of cotton swab onto the new growth being extremely careful not to overlap the dye onto the old growth which had been previously dyed.

In order to apply this dye along the hair part, it is preferred to deliver the liquid directly to the part with the applicator nearly touching the skin as it exits. It has been found that hair brush bristles may serve to blend in the dye in the region of the new growth just as well as a cotton swab formerly used for this purpose. It is a special feature of this invention to provide as a single device a brush having a thin line of blending tufts and a detachable rubber applicator mounted on the brush handle for thumb activation and adapted to apply the bleach and the dye directly to the part prior to blending by the same device. It is thus seen that the dye applicator is an integral component separate from the brush which may be replaced as it wears out without affecting the structure or operation of the applicator.

One object of the invention is to provide a new and improved hair dye applicator.

Another object of the invention is to provide a hair brush and dye applicator as separable components but capable on assembly of delivering bleach and dye in discreet quantities to narrowly prescribed areas of the head and of blending the dye in the hair as desired.

Other objects and advantages of the invention may be appreciated on reading the following description of one copy thereof which is taken in conjunction with the acompanying drawings, in which:

FIG. 1 is a perspective view showing the brush and dye applicator as separate Units;

FIG. 2 is a perspective view showing the brush and dye applicator assembled; and

FIG. 3 is a section taken on the line 3—3 of FIG. 2.

Referring to the drawings, the numeral 6 refers to a comb and brush handle having upper comb teeth 8 and lower dye blending brush tufts 18 in one end thereof, the tufts being formed in segments each having a comparatively narrow cross-section as shown in FIG. 3.

The dye applicator 12 is formed as a single component attachable to the brush by clips 14 which yieldingly clip to the comb and brush between the teeth and the tufts, respectively. The applicator is provided with a thumb operated bulb 14 filled through capped aperture 15 and a communicating extension member 16 integrally joined thereto. Depending from the underside of the member 16 and extending nearly the full length of the blending tufts 10 are bottom aperture nobs 18 which communicate with the member 16 and are adapted to deliver bleach or dye mixtures directly to the line of hair part. The nobs 18 are slightly biased in the direction of the blending tufts 10 so that liquid can be applied between pairs of blending tufts directly to the desired area of the scalp while at the same time the tufts are positioned for the blending operation immediately after the desired liquid has been applied.

In the dyeing operation, first the hair is bleached, using a solution of ammonium chloride and hydrogen peroxide which places the hair in condition to accept the subsequently applied dye. The hair is then usually dried. The next step is to section the hair by forming a part using the comb side of the device. Then the device 12 is employed to apply the dye mixture for a given distance along the part and then to blend the dye into the hair using the blending tufts 10. If the beautician is dyeing new growth of hair in a “touching up” treatment, he must be careful to first bleach and then blend the dye into the hair just from the roots to the end of the new growth being careful not to overlap into previously dyed regions which would cause an undesired and unsightly change of color or tint in these regions. The sectioning, bleaching and blending steps are then continued until all of the new growth is dyed to the desired tint.

It may be appreciated that there is an advantage in deploying the soft rubber nobs relatively close to the blending tufts so that minimum time is lost between the liquid application and the blending which greatly facilitates the blending operation that is so critical to successful treatment. The provision of the nobs adjacent the tufts, assures that the bleach and dye is applied precisely into the part which is a necessary step prior to the blending. Also, the handle and reservoir bulb are completely separable and relatively positionable components permitting the operator to maintain a firm grip on the instrument while deftly applying just the desired amount of bleach and dye using thumb pressure for this purpose. The applicator having these features thus is believed to afford distinct advantages over priorly known like devices such as are shown, for example, in Patent No. 3,147,757.

Various modifications of the invention may be effected by persons skilled in the art without departing from the scope and principle thereof as defined in the appended claims.
