This invention is directed generally to hair coloring, and more particularly to an applicator and methods for applying hair colorants to hair.
Hair coloring is undertaken to change or cover the color of hair for many different reasons. For instance, hair is often colored to cover hair that has turned gray, to lighten or change the shade of hair, or to highlight or lowlight hair. The hair coloring procedures used to generate these results are often markedly different and use different coloring materials. The hair coloring materials may be dyes that may not be easily washed from the colored hair with conventional shampoo and water, or other materials.
For as many reasons exist for a person to color their hair, there exist nearly as many systems for applying color to hair. For instance, hair may be colored by hair professionals in salons using liquid dyes. The dyes are thoroughly mixed prior to application to the hair by a technician or stylist. This process may also be completed at home using dyes purchased at retail stores. A system for applying color to hair is shown in U.S. Pat. No. 6,053,177, which depicts a cartridge coupled to a plurality of hollow dispensing tines. The tines resemble the bristles of a common hair brush. The cartridge includes a piston that forces a hair dye through the tines to contact hair while the cartridge is passed through hair as though brushing hair using a conventional hair brush. While these systems provide methods for applying dye to hair, most of these systems do not facilitate easy to use methods of applying dye to select portions of hair on a person's head. In addition, most conventional systems involve undesirable contact of a person's hands with hair dyes, which can contain irritants.
U.S. Patent Application Publication No. 2004/0211437 describes a hair coloring apparatus including a rotating brush that may be used to apply a solid, semi-solid hair or gel colorant to a person'hair. The colorant is generally held within a cartridge positioned such that the brush comes into contact with the hair colorant during rotation, and then deposits the hair colorant onto the hair. The apparatus described in U.S. 2004/0211437 is not designed to work with liquid hair colorant, as the housing containing the rotating brush does not prevent liquid from exiting the housing. The apparatus is thus generally limited to use in a toy or novelty market, as professional-looking coloring results are difficult to obtain with a solid hair colorant.
Thus, a need exists for a hair coloring apparatus capable of overcoming these and other disadvantages of the conventional systems.
The invention relates to a hair colorant applicator including a housing, and a brush which rotates relative to the housing. Hair colorant may be placed in the housing, and thus on the brush. The housing includes at least one opening for receiving at least one strand of hair and placing the at least one strand of hair in contact with the brush. The brush may then be rotated to apply the hair colorant to the at least one strand of hair, while the hair is drawn through the applicator.
In one arrangement, the hair coloring applicator can include a body forming a handle, a brush which rotates relative to the body, and a housing. The brush is rotatable within the housing, and the housing is designed to receive a liquid hair colorant such that the brush contacts the hair colorant within the housing. The housing includes at least one opening for receiving at least one strand of hair and placing the at least one strand of hair in contact with the brush.
The applicator may be used for a variety of purposes. For instance, and not by way of limitation, the hair coloring applicator may be used to add streaks of bright colors to hair for a fun effect. The applicator may also be used to color a natural streak of hair on a person that is not the same color as the rest of the hair. For example, the applicator may be used to add color to a streak of gray hair so that the gray streak blends in with the surrounding hair. In another example, the hair coloring applicator may be used to apply a highlight, such as a blonde streak, to a head of hair. In yet another example, the applicator may be used to add streaks of multiple colors to a head of hair.
In another arrangement a hair coloring applicator is provided, including a handle, a receptacle that is coupled to the handle and is configured to receive one or more hair colorant ingredients, the receptacle having an opening through which the one or more colorant ingredients are discharged as a mixture, and a shaft that is rotatably mounted to the handle. A squeegee member is operatively coupled to the shaft so that is rotates therewith and includes a plurality of squeegee arms that extend outwardly from the shaft. A slider that slides relative to the receptacle and is positioned between a mix position in which the slider seals the opening in the receptacle during a mixing operation in which the one or more colorant ingredients are mixed into the mixture and an apply position in which the slider is spaced from the opening to create a gap for receiving at least one strand of hair and placing the strand of hair into contact with the plurality of squeegee arms so as to apply the mixture to the strand of hair.
In a further arrangement, a hair coloring applicator includes a handle, a housing that is coupled to the handle and is configured to receive one or more hair colorant ingredients, the housing having a first part and a second part that can be moved relative to the first part to create a gap for receiving a strand of hair, and a shaft that is rotatably mounted to the handle and is at least partially disposed within the receptacle. A squeegee member is coupled to the shaft so that it rotates therewith and includes a plurality of squeegee fingers that extend radially outward from the shaft into mixing contact with the one or more hair colorant ingredients to define a mixture. A motor is operatively connected to the shaft for controllably rotating the shaft and the squeegee member coupled thereto causing the squeegee fingers to contact the strand of hair so as to apply the mixture thereto, the squeegee fingers being initially positioned in a rest position prior to operation of the motor in which none of the squeegee fingers extend into the gap. A cycle switch is electrically connected to the motor for controlling the rotation of the shaft and position of the squeegee fingers such that after the motor is turned off, the squeegee fingers assume the rest position where none of the fingers extend into the gap.
In yet a further arrangement, a hair coloring applicator can included a handle, a housing that is detachably coupled to the handle and is configured to receive and hold one or more hair colorant ingredients, the housing being formed of a first part and a second part that slides relative to the first part so as to create a gap between the two parts to permit the one or more colorants to be discharged from the first part as a mixture, and a shaft that is rotatably mounted to the handle and extend at least partially into the housing. A squeegee member is coupled to the shaft so that it rotates therewith within the housing and includes a plurality of flexible squeegee fingers that extend radially outward for the shaft into mixing contacts with the one or more hair colorant ingredients to define the mixture. A control mechanism is positionable between at least a mix position in which the first and second parts are sealed to one another and the colorant is contained within the housing and an apply position in which the second part is spaced from the first part creating the gap that receives a strand of hair and places the strand of hair into contact with the plurality of squeegee members so as to apply the colorant to the strand of hair.
These and other uses will become apparent upon review of the enclosed drawings and detailed description below.
The accompanying drawings, which are incorporated in and form a part of the specification, illustrate embodiments of the presently disclosed invention and, together with the description, disclose the principles of the invention.
U.S. Patent Application Publication No. 2004/0211437 describes a hair coloring apparatus including a rotating brush that may be used to apply a solid, semi-solid hair or gel colorant to a person's hair. The entire contents of U.S. Patent Application Publication No. 2004/0211437 are incorporated herein in their entirety by reference.
This invention is directed to a hair coloring applicator 10, as shown in
The hair coloring applicator 10 may have one or more brushes 14. The brush 14 may be generally annular or cylindrical. The term “brush” when used in connection with the applicator described herein can be understood to include brushes, combs, picks, teasers, squeegees and any other arrangement having bristles, hairs, arms, fingers, tines, filaments, quills, and any similar protrusions that can apply coloring material to hair and which may be formed of flexible or non-flexible materials (which may preferably be non-absorbent), or may include arrangements having pads of napped material or other absorbent or semi-absorbent material such as a foam or sponge material. The term “napped material” can be understood to include napped, villous, piled, velvet, plush or tufted fabric or material, or any other suitable material that can apply coloring material to hair. The term “absorbent material” can be understood to include foam, sponge, woolen, matted or felted material, or any other suitable material that can apply coloring material to hair. The invention is not intended to be limited in this regard.
The brush 14 may include a plurality of tufts 16, each of which may be formed of a plurality of bristles 18. The tufts 16 may be provided on a rotatable hub 20. The hub 20 may be circular or may have any other suitable shape. The plurality of tufts 16 may together form a generally annular brush. The brush 14 may be rotatably mounted to a body 22 which forms a handle for a user to grasp. The bristles 18 may extend from the brush 14 and may be angled away from the direction of rotation of the brush 14. The body 22 contains a motor 66 (shown in
The brush 14 may be configured to be contained in a housing 24. The housing 24 may be substantially circular, and encloses the brush 14. The housing 24 may substantially prevent inadvertent contact with the bristles 18 while the brush 14 is rotating and thereby prevent the hair colorant 12 from inadvertently contacting unwanted areas such as a user's face, hands, arm, clothing, furniture, or other objects. The housing 24 may be aligned with the body 22 such that the axis of rotation of the brush 14 is generally perpendicular to the body 22. A suitable gear mechanism 68 (shown in
The housing 24 may also include at least one opening 26 for application of hair colorant 12 to at least one strand of hair. The opening 26 may be covered with a slider 28 that is used to hold at least one strand of hair against the brush 14. The slider 28 may have an inside surface that is flat or may be convex, such as a convex cylindrical shape, which enables hair placed within the opening 26 to slide smoothly past the slider 28. The slider 28 is generally L-shaped having a floor which is positioned underneath the housing 24, and is biased inwardly into a closed position by a bias such as a spring 70 (shown in
In the arrangement shown in
FIGS. 2 to 4 illustrate another arrangement of the hair coloring applicator 10. In this arrangement, a portion of the housing 24 and the brush 14 are integrated in a removable cartridge 36. The applicator 10 also includes a housing base 38 attached to the body 22 that supports the cartridge 36 when installed. The housing base 38 also supports the slider 28, and the gear mechanism 68 for the motor 66. The cartridge 36 includes a coupling 40 that can be mated with a corresponding coupling (not shown) on the housing base 38, and which connects the brush 14 to the motor.
The cartridge 36 may include the opening 26, and a second opening 42 for the coupling 40. The openings 26 and 42 may be covered by a peel-away material 44 to seal the cartridge. The cartridge 36 can thus contain liquid hair colorant 12 predisposed therein. To install the cartridge, a user first removes the material 44 covering the openings 42 and 26, and clicks the coupling 40 into place on the housing base 38. The brush 14 may then be rotated by operating the operating lever 30 to mix the hair colorant 12 thoroughly, and to coat the brush 14 with the hair colorant. Hair may then be placed within the slider 28, and the hair colorant 12 applied to the hair as in the previously described arrangement.
In the arrangement shown in
In the illustrated arrangement, each squeegee arm 76 is bifurcated into two smaller arms or fingers 80 such that the squeegee arm 76 is generally in the shape of an F. Each finger 80 extends radially outwardly from the hub 78 and has a proximal end attached to a perpendicular portion 82 that is joined to the hub 78 and also has a free distal end 84. The free distal ends 84 are cut at an inclined angle to an axis of rotation of the hub 78. The squeegee arms 76 are arranged around the hub 78 with alternate arms 76 presented in opposite orientations, such that one squeegee arm has its fingers 80 at one axial end of the hub 78, and the neighboring squeegee arm 76 has its fingers 80 at the other axial end of the hub 78. The arms may be arranged so that a finger 80 on one squeegee arm 76 is aligned with a gap between the fingers 80 on the following squeegee arm 76. Alternating the orientation of the squeegee arms 76 also ensures that the inclined free distal ends 84 of the fingers 80 are inclined in opposite directions. These arrangements aid in thorough mixing of the hair colorant 12 within the housing, and also in movement of the hair colorant 12 to the opening 26 and application to the hair.
It will be appreciated that the arrangement of squeegee arms 76 may be varied while still providing a thorough mixing and application of the hair colorant 12. For example, the squeegee arms 76 may not be bifurcated, but may have one or more apertures therein to allow the arms 76 to travel easily through the colorant 12. Single arms 76 may be provided on the hub 78, with the arms positioned at varying axial locations so that appropriate mixing of the colorant 12 is achieved. As shown in
The squeegee arms 76 may be slightly longer than an inner radius of the housing 24. In this manner, the flexible squeegee arms 76 can sweep the inner surface of the housing 24 as they are rotated by the motor 66. Additionally, this ensures that the squeegee arms 76 come into contact with hair placed within the gap 52, providing for a thorough transfer of hair colorant 12 onto the hair.
