HAIR COLOURING DEVICE
HELD OF INVENTION
100011 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 MENTION
J0002 1 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.
100031 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.
100041 One such method utilizes a cap with holes therein that is placed 011 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
CA 02978637 2017-09-05
WO 2016/138553 PCT/AU2016/000066
the hair the cap is removed. This technique is time consuming and tedious and
does not allow for
targeting particular hair strands.
[00051 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.
100061 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,
100071 U.S. Pat. No. 6,5611,404 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.
[00081 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.
100091 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.

applicator tips 21, 22
either fixed or removably attached thenzon. According to an embodiment, the
cartridges 19, 20
may be filled in an unclipped position with an external colour resource or the
cartridges 1.9, 20
may be filled with the external colour resource through. the applicator tips
19, 20 when the
cartridges 19, 20 are in clipped position.
100331 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 colour= 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
