Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application is related to Australian provisional patent application number 2015900772 filed on Mar. 5, 2015, Australian standard patent application 2016201447 filed on Mar. 4, 2016, and PCT application PCT/AU2016/000066 filed on Mar. 4, 2016. The entire disclosure of the above patent applications is hereby incorporated by reference.

FIELD OF INVENTION

The present invention relates generally to the colouring of hair, and more particularly, to a hair colouring device and method that allows accurate, non-messy and even application of a hair colouring composition to the hair, in particular to one or more strands of hair more quickly and effectively.

BACKGROUND OF THE INVENTION

There are several reasons for a people to colour their hair either by themselves at home or through hair professionals in salons. The reasons for instance may be to cover hair that has turned gray, to change the shade of their hair, or to highlight hair. Also, hair colouring may be used to give glamorous look to the hair, especially with temporary colour compositions. There exist several methods or means for applying colour to hair. The dyes are often thoroughly mixed with the hair using liquid dyes by the hair professionals. This process becomes more completed at home. Generally, the professionals at salon and people at home are found colouring the hair by using a brush, comb, applicator and hair colouring composition in semi-liquid or liquid state. While this method for applying colour to the hair is very common, this method does not facilitate ease in applying colour to the selected portions of the hair, this method also involves undesirable contact of a person's hands and/or skin with hair colours, which may contain irritants.

Various hair colouring or touch up devices and methods for hair colouring or highlighting the hair has been provided in the prior art, some of which will now be described.

One such method utilizes a cap with holes therein that is placed on a person's head. Selected strands of hair that are to be highlighted, or coloured, are pulled though the holes in the cap. The colourant is then applied to the strands of hair extending through the holes in the cap. After the colourant has been applied and has been left for the required processing time to colour the hair the cap is removed. This technique is time consuming and tedious and does not allow for targeting particular hair strands.

U.S. Pat. No. 6,237,608 by Kari at al. describes about a dispensing apparatus for metallic foil that can be used by beauticians and hair stylists to colour or highlight the hair. The foil method as disclosed allows smaller, more independent, and more consistently variegated sections to be coloured effectively reducing risk of the colour bleeding onto surrounding hair. However, even with these advantages, the foil method is very time consuming and expensive and does not colour the hair all the way to the scalp.

U.S. Pat. No. 6,675,812 by Wiley et al. describes about a hand-held dispenser having a comb or brush and an optional sponge to apply, and distribute liquids such as dyes to the hair and/or that can be used to apply dye, and simultaneously comb and spread the dye onto the hair. This method colours one side of the hair and does not allow precise colouring.

U.S. Pat. No. 6,568,404 by Mitchem at al. describes about an applicator for depositing a hair treatment fluid to strands of hair. As described, the applicator is in the form of a longitudinal container with a hook-shaped end. The hair strands are placed in the hook-shaped end, and the applicator is drawn along the length of the strand to deposit the treatment fluid onto the strand. This is another exemplary prior art applicator device used for applying liquid colourants. This method colours one side of the hair and does not allow precise colouring.

Therefore prior art devices discussed above and others for hair colouring have been provided in the prior art. Though these prior art devices may be suitable for the specific individual or professional use to which they address, they differ from the present proposed invention.

Accordingly, there is a need for a hair colouring device that can address or at least ameliorate the short comings associated with conventionally employed devices, methods or techniques for hair colouring or highlighting.

Before explaining at least one embodiment of the present invention in detail, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.

In accordance with a preferred embodiment, a hair colouring device generally identified by reference numeral 10 or 40 or 50 is described with reference to FIGS. 1 through 6. As best shown in the exploded view (in FIG. 2), the hair colouring device 10 includes a top housing 11, and a bottom housing 12. The top housing 11 includes a proximal end 11a and a distal end 11b. Similarly the bottom housing 12 includes a proximal end 12a and a distal end 12b. The top housing 11 and the bottom housing 12 include openings 13 and 14 respectively.

Further referring to the FIG. 2, the hair colouring device 10 includes a first cartridge carrier 15 with an interior cavity 17 for receiving a first colourant-filled cartridge 19. The first cartridge carrier 15 is removably disposed within the opening 13 provided in the top housing 11. The device 10 also includes a second cartridge carrier 16 with an interior cavity 18 for receiving a second colourant-filled cartridge 20. The second cartridge carrier 16 is removably disposed within the opening 14 provided in the bottom housing 12. The first cartridge carrier 15 includes a proximal end 15a and a distal end 15b. Similarly the second cartridge carrier 16 includes a proximal end 16a and a distal end 16b. It should be understood that the interior cavities 17, 18 of the first cartridge carrier 15 and the second cartridge carrier 16 are suitably sized such that the first colourant-filled cartridge 19 and the second colourant-filled cartridge 20 can either tightly fit within the interior walls of the cavities 17, 18 or sized slightly larger than the size of the first colourant-filled cartridge 19 and the second colourant-filled cartridge 20.

According to some embodiment, as shown with reference to FIG. 5, the hair colouring device 50 may embody the readily designed colourant-filled cartridges 19, 20 that can easily be clipped in and out of the top housing 11 and the bottom housing 12 respectively when the device 50 is in open position. The colourant-filled cartridges 19, 20 will have applicator tips 21, 22 either fixed or removably attached thereon. According to an embodiment, the cartridges 19, 20 may be filled in an unclipped position with an external colour resource or the cartridges 19, 20 may be filled with the external colour resource through the applicator tips 19, 20 when the cartridges 19, 20 are in clipped position.

According to some embodiment, the device 10 instead of using the first colourant-filled cartridge 19, and the second colourant-filled cartridge 20 may employ suitably designed hollow cavities or reservoirs for holding the various forms of the colourants, especially colourant in liquid form that can flow through the applicator tips 21, 22 on to the strands of hair like some other texturing or hair styler devices used for colouring the hair. These reservoirs may be filled with an external colour resource removably or permanently attached with the device 10. According to an embodiment, the top housing 11 and the bottom housing 12 can be configured to be hollow inside with no cartridge carriers 15, 16 and colourant-filled cartridges 19, 20 required. The top hollow cavity within the top housing 11 and the bottom hollow cavity within the bottom housing 12 would act as the reservoirs which can be filled with various forms of the colourants through the applicator tips 21, 22 or directly injecting the colourants inside the reservoirs through suitable external means by removing the tips 21, 22. According to the same embodiment, each of the applicator tips 21, 22 may be disposed directly at proximal end of the top housing and the bottom housing respectively.

Further according to the preferred embodiment, as shown in FIG. 2, the pair of applicator tips 21 and 22 may be removably grooved to proximal ends 15a, 16a of the first cartridge carrier 15 and the second cartridge carrier 16 respectively. The applicator tips 21 and 22 preferably comprise some tiny apertures thorough which the colourant can be fed onto the strands of hair while in use. As discussed above, the applicator tips 21, 22 may also be used to fill the first colourant-filled cartridge 19, and the second colourant-filled cartridge 20 or the reservoirs. The applicator tips 21, 22 are configured to contact the strands of hair without snagging the hair. These applicator tips 21, 22 provided in the device 10 allows two sided colouring of the hair strands simultaneously. The applicator tips 21, 22 may vary in design preferably, but not limited to circular or star like. The varying designs of the applicator tips 21, 22 may then be used by the user to stamp various shapes of colour onto the strands of hair. During use, when the device 10 or 40 or 50 is in use the applicator tips 21, 22 come together to hold the one or more strand of hair therebetween for colouring. The alignment of the applicator tips 21, 22 with respect to each other depends on the pressure applied by the user using the device 10 or 40 or 50. When the user using the device applies no pressure then the applicator tips 21, 22 are normally aligned, as shown in FIG. 6A, when the user applies maximum pressure on the device while in use, the applicator tips 21, 22 are fully aligned with respect to each other as seen in FIG. 6C. Similarly, if just a small amount of pressure is applied the applicator tips 21, 22 are just partially aligned, as seen in FIG. 6B.

Referring again to FIG. 1-FIG. 2, the top housing 11 and the bottom housing 12 have an engagement mechanism 23 at the corresponding distal ends 11b and 12b. The engagement mechanism 23 helps the top housing 11 and the bottom housing 12 to snap fit and allow a user to alternate the device 10 between a closed position and an open position to dispense or block dispensing of the colouring composition or formulation. According to the described embodiment, the device 10 or 40 may include a replaceable cap 24 that fits over the pair of applicator tips 21, 22 to securely block dispensing of colouring composition when the device is not in use and to safely store the device 10 or 40 for future use. It is to be understood that any other engagement mechanism 23, as shown in FIG. 5 may also be used to meet above mentioned objective.

The first colourant-filled cartridge 19 and the second colourant-filled cartridge 20 or the reservoirs may contain hair colouring formulation in solid form or liquid form or semi solid form like cream or any combinations thereof. The colourant/dye contained in the cartridges 19 and 20 may be permanent or semi-permanent and temporary in nature.

It should also be understood that, according to at least one embodiment of the present invention, the cartridges 19, 20 contained may be permanently fixed within the device 10 or 40 or may be replaceable. Also, according to some other embodiment, the cartridges 19, 20 may be capable of being refilled using an external colour resource preferably using external means, for example a tube. Still in some other embodiment, the device 10 or 40 may deploy a canister of colour to feed the cartridges 19, 20. The canister may be permanently or removably attached to the device 10 or 40.

The devices 10 or 40 or 50 as stated above in the objectives is an instant colouring device ready for use by the user at any time that do not require a laborious work of thoroughly mixing the colourant/dyes with solvent or mixing of the liquid dyes. However, it is to be understood by those skilled in the art that the user may need to allow some processing time for the device 10 or 40 or 50 to get it ready for instant colouring in case the device 10 or 40 or 50 is not ready for instant colouring.

It is also to be understood that the scope of using the colourant filled cartridges 19, 20 is not limited to containing any specific colour. One or more colours may be contained in the cartridges 19, 20, which may include, but are not limited to, red, yellow, orange, purple, brown, black, any combinations or shades thereof, or others. According to some other embodiment, the colouring composition contained in the cartridges 19, 20 may be separated into distinct sections in the cartridge 19, 20 which may preferably be required by the user to apply different colour stripes to the strands of hair.
