## Background
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention generally is in the field of coloring hair, and more particularly is in the field of portable, disposable devices for coloring hair regrowth, particularly hair roots, and methods for coloring hair using such devices.
2. Prior Art
Salon owners continuously hear complaints from salon clients that their hair regrowth starts appearing shortly after receiving beautiful, expensive, professional color. More specifically, as human hair is in a continuous state of growth, very soon after a salon client has her or his hair colored, the salon client's hair roots begin to show, and the hair roots are not the colored, but are the salon client's original hair color. This can lead to multi-colored hair and public knowledge that the salon client is coloring her or his hair.
Currently, to avoid the hair regrowth from showing, the salon client has several choices for maintaining the color of the hair and for coloring the regrowth of hair roots. One such choice is commercially available hair colorants, such as those that can be purchased in the store. However, many salon clients will not use such products in fear that it will ruin the professional color. Additionally, such commercially available products can be messy and difficult to apply to the hair, and even messier and more difficult to apply just to the hair root. Further, the color choices currently on the market often will not allow the salon client a precise match to the professional color, and the salon client has to guess the quantity to apply, and has to mix various colors and other chemicals and solutions together, which can be a hit or miss process. Therefore, the use of such commercially available products is not a satisfactory option of many salon clients.
Another choice is to continuously visit the salon for hair color touch ups between major coloring visits. During such interim visits, the salon professional can color the hair root regrowth using the professional color originally used on the hair. However, such interim visits can be both time-consuming and expensive. The salon client must take time out of her or his day one a week or once every other week for such interim visits. Additionally, the salon professional often must charge the salon client for each such interim visit. Currently, many clients go to the salon every two to four weeks in need of such small but noticeable regrowth touch-ups, and in many cases, just a small perimeter touch-up. For the salon professional, this is a low profit activity and for the salon client, this is a high cost and time consuming activity. Therefore, such interim visits also are not a satisfactory option for many salon clients.
Accordingly, there is a need for a device and method that allows for the home coloring of hair regrowth, and especially hair root growth, between salon visits. There is also a need for such a device and method that is easy to use and to apply to the hair without messy or difficult mixing and application. There is a further need for such a device and method that is less costly and time-consuming than an equivalent visit to the salon for professional coloring touch-ups. There is an additional need for such a device and method that uses the same color formulation that was use by the salon professional for the initial hair coloring. There is also a need for such a device and method that is portable and compact such that the salon client can carry the device on her or his person or while traveling and can use the device and carry out the method without the need of additional devices. It is to these needs and others that the present invention is directed.
BRIEF SUMMARY OF THE INVENTION
Briefly described, the present invention is a one-step, economical, precise way for the salon client to just touch-up regrowth of hair without causing damage to the rest of the hair.

The present invention is a one-step, economical, precise way for the salon client to just touch-up regrowth of hair without causing damage to the rest of the hair. The present invention is suitable for use with most hair growth, including head hair, eyebrows, mustaches and beards. Currently, to the best of the inventor's knowledge and belief, there is nothing on the market that does not include a specific mixing step and that allows the salon client to apply the hair colorant to a precise area without effecting unwanted areas.
Referring now to FIG. 1, an illustrative example of the device 10 comprises a larger container 12, an applicator 14, and a connecting ring 16 for attaching the applicator 14 to the larger container 12. Within the container 12 are located at least one ampoule 18, two being shown in FIG. 1, and an optional mixing ball 20. As will be disclosed, various combinations of these components are contemplated in this invention. Further, throughout the drawings, hair colorant 22 is represented by circles (o), carrier 24 is represented by squiggly lines ( ̃), a first additional hair care product such as conditioner 26 is represented by xs (x), and a second additional hair care product 28 is represented by triangles (Δ). The final hair color solution 32 is represented by a squiggly line overlaying a circle.
Hair colorant 22 can be any of the known or future developed hair colorants, and can be prepackaged in ampoule 18 in a known manner. Carrier 24 can be any carrier or catalyst useful for formulating hair coloring solution 32, and also can be prepackaged in ampoule 18 in a known manner. Suitable carriers include but are not limited to peroxide and ammonia and other known carriers and catalysts. Carrier 24 preferably is a peroxide, as the combination of hair colorant 22 and peroxide 24 produces a permanent hair coloring solution 32. Additional hair care products 28 include but are not limited to conditioners 26, oils, crèmes, dyes, tints, lotions, bleaches, mousses and the like.
Larger container 12 preferably is hollow, has a closed bottom and sides and an open top, has a length between approximately 1 inch and 4 inches, and a diameter or width between approximately 1⁄4 inch and 1 inch. Larger container 12 can be somewhat larger or smaller; however, it is preferable that larger container 12 be of such a size that it can be easily manipulated by the user with one or two hands. More specifically, larger container 12 preferably is structured to hold and contain liquids. Large container 12 preferably is made from a flexible material such as an amorphous (non-crystalline) polymer such that larger container 12 can be squeezed by the salon client. Such materials are known in the art and include without limitation polyethylene terephthalate (PET) and high density polyethylene (HDPE). Other less flexible and rigid materials also can be used, but are not preferred.
Applicator 14 preferably is a material shaped to generally correspond to the cross sectional shape of larger container 12 such that applicator 14 can more easily be attached to larger container 12. Applicator 14 is manufactured from a material that will allow a fluid contained within larger container 12 to travel through applicator 14 in a controlled manner. Applicator 14 preferably is a material that falls within the general known categories of sponges, brushes, and filters that can be used as fluid or solution applicators. One of ordinary skill in the art can select an appropriate applicator 14 material for use with the hair color solution contained within larger container 12 and ampoules 18 without undue experimentation.
Connecting ring 16 is optional and can serve at least two purposes. First, connecting ring 16 can allow applicator 14 to be connected to larger container 12. Second, connecting ring 16 can comprise a breakable or puncturable membrane 30 (see FIG. 2) sealing larger container 12 closed. Connecting ring 16 is a ring-like structure having a side wall but no top or bottom walls and can be attached to larger container 12 via any conventional means, such as for example a screw thread or friction. Membrane 30 can be attached to connecting ring 16 via any conventional means, such as for example adhesive, heat welding, or sonic welding. Membrane 30 can be any suitable material such as a thin polymer. Such materials are known in the art and include without limitation low density polyethylene (LDPE). If used, membrane 30 is attached about the internal circumference or perimeter of connecting ring 16.
Ampoules 18 are relatively small breakable vials filled with a selected hair care product, preferably in solution or liquid form. Ampoules 18 are of such a size that at least one, and preferably two or more, ampoules 18 can fit within the hollow interior of larger container 12. Thus, ampoules 18 can be of various sizes so long as ampoules 18 fit within larger container 12. Ampoules 18 are structured to hold and contain liquids. Ampoules 18 preferably are made from a rigid material such as a crystalline or other brittle polymer or glass such that ampoules 18 can be broken, thus releasing the solutions contained within ampoules 18 when larger container 12 is squeezed by the salon client. Such materials are known in the art and include without limitation glass, ceramic, polyvinylchloride (PVC), polypropylene, and polystyrene. Other flexible and less rigid materials also can be used, but are not preferred.
Mixing ball 20 is a relatively small sphere or other shaped structure and is contained within larger container 12. The purpose of mixing ball 20, mixing ball 20 being optional, is to assist in mixing the solutions contained within ampoules 18 and larger container 12 together for application by the salon client.
Referring now to FIG. 2, a first embodiment of the device 10 of the present invention comprises a breakable ampoule 18 of a first solution, such as hair colorant 22, contained within larger container 12 also containing a second solution, such as carrier 24. Alternatively, as some hair colorants 22 do not need a carrier or catalyst, larger container 12 can contain only ampoule 18 containing hair colorant 22 and no second solution. Larger container 12 further comprises a sponge applicator 14 through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, sponge applicator 14 has a flat application surface 40. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed to assist in dispensing hair color solution 32. Ampoule 18 preferably is manufactured from a breakable material such that ampoule 18 can be broken and its contents released into larger container 12 (see FIG. 8). Connecting ring 16 in this example comprises membrane 30, which can be ruptured via pressure or via tube 34 (see FIG. 8). For example, after ampoule 18 is broken and hair colorant 22 is mixed with carrier 24 within larger container 12, further squeezing of larger container 12 by the salon client will increase the pressure within larger container 12, thus rupturing membrane 30 and allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50.
Referring now to FIG. 3, a second embodiment of the device 10 of the present invention comprises first ampoule 18A of a first solution, such as hair colorant 22, and second ampoule 18B of a second solution, such as carrier 24, both contained within larger container 12. Larger container 12 further comprises a filter applicator 14, such as a cotton or other fiber filter, through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, filter applicator 14 has a flat application surface 40. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed to assist in dispensing hair color solution 32. Ampoules 18A, 18B preferably are manufactured from a breakable material such that ampoules 18A, 18B can be broken and their contents released into larger container 12. Connecting ring 16 in this example does not comprise membrane 30. Either connecting ring 16 has a puncturable lower wall 36 or larger container 12 has a puncturable upper wall 38, or both, which can be ruptured via pressure or via tube 34 (see FIG. 8). For example, after ampoules 18A, 18B are broken and hair colorant 22 is mixed with carrier 24 within larger container 12, further squeezing of larger container 12 by the salon client will increase the pressure within larger container 12, thus rupturing wall 36 or 38 or both and allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50.
Referring now to FIG. 4, an alternative of the second embodiment of the device 10 of the present invention comprises first ampoule 18A of a first solution, such as hair colorant 22, and second ampoule 18B of a second solution, such as carrier 24, both contained within larger container 12. Also contained within larger container 12 is a third solution or liquid, such as an additional hair care product, such as for example hair conditioner 26. Larger container 12 further comprises a filter applicator 14, such as a cotton or other fiber filter, through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, filter applicator 14 has a tapered application surface 40. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed to assist in dispensing hair color solution 32. Ampoules 18A, 18B preferably are manufactured from a breakable material such that ampoules 18A, 18B can be broken and their contents released into larger container 12. Connecting ring 16 in this example comprises membrane 30, which can be ruptured via pressure or via tube 34 (see FIG. 8). For example, after ampoules 18A, 18B are broken and hair colorant 22 is mixed with carrier 24 and conditioner 26 within larger container 12, further squeezing of larger container 12 by the salon client will increase the pressure within larger container 12, thus rupturing membrane 30 and allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50.
Referring now to FIG. 5, a third embodiment of the device 10 of the present invention comprises first ampoule 18A of a first solution, such as colorant 22, second ampoule 18B of a second solution, such as carrier 24, and one or more additional ampoules 18C of additional solutions such as conditioners 26, oils or other hair care products, all contained within larger container 12. Larger container 12 further comprises brush applicator 14 through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, brush applicator 14 has a flat application surface 40. Brush applicator 14 is of a known type, comprising bristles 42 attached to a porous or perforated base 44. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed to assist in dispensing hair color solution 32. Ampoules 18A, 18B, 18C preferably are manufactured from a breakable material such that ampoules 18A, 18B, 18C can be broken and their contents released into larger container 12. Connecting ring 16 in this example does not comprise membrane 30. Either connecting ring 16 has a puncturable lower wall 36 or larger container 12 has a puncturable upper wall 38, or both, which can be ruptured via pressure or via tube 34 (see FIG. 8). For example, after ampoules 18A, 18B, 18C are broken and hair colorant 22 is mixed with carrier 24 and conditioner 26 within larger container 12, further squeezing of larger container 12 by the salon client will increase the pressure within larger container 12, thus rupturing wall 36 or 38 or both and allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50.
Referring now to FIG. 6, an alternative of the third embodiment of the device 10 of the present invention comprises first ampoule 18A of a first solution, such as colorant 22, second ampoule 18B of a second solution, such as carrier 24, and third ampoule 18C of and additional solution, such as conditioner 26, all contained within larger container 12. Also contained within larger container 12 is a fourth solution or liquid, such as an additional hair care product 28. Larger container 12 further comprises brush applicator 14 through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, brush applicator 14 has a tapered application surface 40. Brush applicator 14 is of a known type, comprising bristles 42 attached to a porous or perforated base 44. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed to assist in dispensing hair color solution 32. Ampoules 18A, 18B, 18C preferably are manufactured from a breakable material such that ampoules 18A, 18B, 18C can be broken and their contents released into larger container 12. Connecting ring 16 in this example comprises membrane 30, which can be ruptured via pressure or via tube 34 (see FIG. 8). For example, after ampoules 18A, 18B, 18C are broken and hair colorant 22 is mixed with carrier 24, conditioner 26 and fourth solution 28 within larger container 12, further squeezing of larger container 12 by the salon client will increase the pressure within larger container 12, thus rupturing wall 36 or 38 or both and allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50.
Referring now to FIG. 7, a fourth embodiment of the device 10 of the present invention comprises larger container 12 having first compartment 60 containing a first solution, such as colorant 22, and second compartment 62 containing a second solution, such as carrier 24. Larger container 12 further comprises sponge applicator 14 through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, sponge applicator 14 has a flat application surface 40. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed to assist in dispensing hair color solution 32. Compartments 60, 62 preferably comprise a breakable, rupturable or puncturable top wall 64 that can be broken, ruptured or punctured and the contents of compartments 60, 62 released. Connecting ring 16 in this example comprises membrane 30, which can be ruptured via pressure or via tube 34 (see FIG. 8). For example, after top walls 64 are broken by the squeezing of larger container 12 by the salon client, hair colorant 22 is mixed with carrier 24 within connecting ring 16. Then, the salon client will increase the pressure within larger container 12 by further squeezing, allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50. Alternatively, side walls 66, 68 of first compartment 60 and second compartment 62, respectively, can comprise a breakable, rupturable or puncturable material that can be broken, ruptured or punctured and the contents of compartments 60, 62 released and mixed within the now single compartment formed in larger container 12 when side walls 66, 68 rupture.
Referring now to FIG. 8, a sectional side view of the embodiment of the device 10 of the present invention shown in FIG. 3 with the two ampoules 18A, 18B broken and the solutions 22, 24 mixed in preparation for use is illustrated. In this illustrative example, the device 10 of the present invention comprises first breakable (shown as broken) ampoule 18A of a first solution, such as hair colorant 22, and second breakable (also shown as broken) ampoule 18B of a second solution, such as carrier 24, both contained within larger container 12. Larger container 12 further comprises a filter applicator 14, such as a cotton or other fiber filter, through which hair coloring solution 32 can be dispensed directly onto the chosen hair area 50 (see FIG. 9). As shown in this figure, filter applicator 14 has a flat application surface 40. Larger container 12 preferably is manufactured from a squeezable material so that larger container 12 can be squeezed by the user, as indicated by arrows S, to place pressure on and break ampoules 18A, 18B. Once ampoules 18A, 18B are broken, hair colorant 22 and carrier 24 mix within larger container 12 to form hair coloring solution 32. Connecting ring 16 in this example does not comprise membrane 30. Either connecting ring 16 has a puncturable lower wall 36 or larger container 12 has a puncturable upper wall 38, or both, which can be ruptured via pressure or via tube 34. For example, after ampoules 18A, 18B are broken and hair colorant 22 is mixed with carrier 24 within larger container 12, connecting ring 16 can be screwed or otherwise placed onto the top of larger container 12 such that tube 34, shown with a piercing end 70, punctures lower wall 36, upper wall 38, or both, or membrane 30 if a membrane 30 configuration is used. Further squeezing of larger container 12 by the salon client will increase the pressure within larger container 12, thus allowing hair coloring solution 32 to be forced through applicator 14 and dispensed onto hair area 50. Tube 34 can be attached to connecting ring 16 via struts 72 or the like.
FIG. 9 illustrates an alternative embodiment of the present invention showing an elongated larger container 12 structured to receive and hold two ampoules 18A, 18B in a stacked relationship.
