CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This document claims priority to French Application Number
03 08542, filed Jul. 11, 2003 and U.S. Provisional Application No.
60/493,765, filed Aug. 11, 2003, the entire contents of which are
hereby incorporated by reference.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention concerns a device designed to isolate
a lock of hair for the purpose of applying a hair product thereto.
By way of example, the invention can be particularly advantageous
for applying a coloring/decoloring product.
[0004] 2. Discussion of Background
[0005] A variety of techniques are currently used to apply a hair
product to individual locks of hair.
[0006] According to a first method, a perforated bonnet is placed
on the customer's head. Using a tool with one end configured in the
form of a hook, the locks of hair lying directly below the
perforations are extracted from the bonnet. The product is then
applied uniformly onto these locks of hair by means of a brush.
After an appropriate treatment time, the bonnet is removed. The
action of the coloring product is then neutralized by means of a
shampoo. A method of this kind is described for example in U.S.
Pat. No . 4,961,439.
[0007] This method has numerous drawbacks. The method is painful
for the customer when the locks of hair are extracted from the
bonnet and when the bonnet is removed. In addition, this method is
time-consuming and awkward to carry out. Moreover, there is a
significant risk that the product will penetrate through the holes
in the bonnet and stain the scalp.
[0008] In another method, the lock of hair is placed on a pallet.
The product is then applied to the lock of hair by means of a
brush. The locks of hair are left exposed to the air and separated
from the rest of the hair by cotton pads placed at the roots of the
hair. After the requisite treatment time, the hair is washed in a
conventional manner. Again, this method is time-consuming and
awkward. Moreover, the locks of hair treated are unavoidably placed
in contact with the rest of the hair, which to a large degree can
spoil the appearance of the finished result.
[0009] Methods to avoid contact between the locks of treated hair
and the rest of the hair have been described, in particular in
GB2371744, WO9738602 and U.S. Pat. No. 5,816,268. In these
documents, a sheet of flexible plastic arranged under the lock of
hair to be treated is used in order to isolate it from the rest of
the hair. The product is then applied to the lock of hair. In
WO9738602, the sheet is held on the hair by means of a Velcro type
fastening strip. After applying the product, the lower part of the
sheet is folded back to cover the lock of treated hair with the
folded sheet adhering to the hair by virtue of the presence of
product. In GB2371744, the sheet arranged under the lock of hair is
bonded at its lower end to a second sheet which is folded back to
cover the lock of hair treated. A Velcro type fastening strip is
provided on each sheet to attach the two sheets together in the
folded position. In U.S. Pat. No. 5,816,268, the sheet placed under
the lock of hair is simply held in contact with a second sheet as
each of the sheets includes a folded first end into which a second
end of the other sheet is inserted, with the two sheets not being
attached together. After coating the lock of hair with product, the
second sheet is moved apart from the first and placed on the lock
of hair coated with product. In this position, the second sheet
still cannot be attached to the first sheet as no means of
attachment is provided.
[0010] In these documents, the product is applied starting from the
upper part of the isolated lock of hair. Using this method,
however, it is difficult to apply the product with a clear
demarcation at the upper part of the lock of hair, particularly if
it is desired to start applying the product some distance away from
the scalp.
SUMMARY OF THE INVENTION
[0011] One of the objects of the invention is to create a device to
isolate a lock of hair before applying a product which avoids some
or all of the drawbacks of the prior art.
[0012] Another object of the invention is to create a device which
enables a product to be applied with a clear demarcation at the
upper part of the lock of hair.
[0013] A further object of the invention is to provide a device
which enables products to be applied to the hair without risk of
the product migrating from one lock of hair to another. In
accordance with a particularly preferred form, products of
different colors or different tones can be applied to the same head
of hair while preventing migration into undesired locations.
[0014] It is also an object of the invention to create a device to
isolate a lock of hair which additionally makes it possible to
squeeze out the product applied to the lock of hair before
rinsing.
[0015] A further object of the invention is to provide a device for
isolating a lock of hair which can be used several times.
[0016] The invention provides a device to isolate at least one lock
of hair to which a product is to be applied which includes a first
and a second sheet each including a first end and a second opposite
end. The device further includes an attachment device, integral
with the first and/or the second sheet, to attach the two sheets
together in a reversible manner in proximity to their first end,
over the lock of hair to be isolated. In addition, the two sheets
are configured so as to have their second end free when they are
attached together in proximity to their first end.
[0017] According to the invention, the expression "attached in
proximity to the first end" means that the sheets are attached
together closer to the first end than to the second. Preferably the
sheets are attached as close as possible to the first end,
preferably along this end.
[0018] A device of this kind can be attached to the lock of hair to
be isolated before applying the product, and the product can be
applied by separating one of the sheets by the second end which is
free. The means of attachment thus make it possible to delineate,
in the upper part of the hair, the area in which the product is to
be applied so that the product can be applied according to a clear
demarcation at the upper part of the lock of hair. The lock of hair
isolated in this way can start in proximity to the scalp, but this
lock of hair can also be started at various distances from the
scalp, by attaching the device at a location spaced from the scalp.
Thus, on the same head of hair, colored locks of hair can be
produced at different distances from the scalp in order to achieve
particular effects on the hair.
[0019] With this device, a single piece of hair can be isolated,
for example in the form of a fringe, or as several smaller locks of
hair.
[0020] The two sheets can have the same shape, for example
rectangular or trapezoidal, so that they can be superimposed. It is
thus possible to completely isolate the lock of hair from the rest
of the hair.
[0021] The sheets can be impermeable to the product so as to
prevent the product from transferring to the rest of the hair.
[0022] At least one of the sheets can be made of a transparent or
translucent material. This enables the user to observe the lock of
hair treated during the product treatment time.
[0023] The sheets can be made of plastic material, such as a
polyolefin, for example polyethylene or polypropylene. A device of
this kind can then be readily cleaned with water, for example.
[0024] The attachment means may include a first part provided on
the first sheet and a second part provided on the second sheet,
with the two parts being capable of cooperating between them to
allow reversible attachment. As the attachment is reversible, the
device can be used several times.
[0025] The first part may include a strip equipped with loop
elements and the second part includes a strip equipped with hook
elements.
[0026] Alternatively, the attachment means can be composed of a
clamp formed by two arms connected together by a hinge, with each
arm being integral with one sheet. Here again, given that the
attachment is reversible, the device can be used several times.
[0027] The attachment means can be configured so as to attach the
two sheets together along a rectilinear edge. The product can then
be applied so that the application is started at an upper portion
of the lock of hair, along a rectilinear edge. Alternatively, means
of attachment may be chosen which enable the two sheets to be
attached together along an edge of any other shape, for example a
concave line, a convex line, a wave, etc. It is thus possible to
obtain particular effects in the hair, which can be reproduced over
the entire head of hair.
[0028] The attachment means can be configured so as to prevent the
product applied to the isolated lock of hair from being transferred
to the part of the hair adjacent to the attachment means. The
product which has been applied according to a clear demarcation is
not liable to migrate, after it has been applied, to the part of
the hair located above the attachment means.
[0029] The invention also relates to a process for the application
of a hair product to at least one lock of hair. A preferred form of
the process includes the following steps in the order listed:
[0030] a) lift at least one lock from the hair;
[0031] b) arrange a first sheet under the lock of hair;
[0032] c) arrange a second sheet over the lock of hair, against the
first;
[0033] d) attach the two sheets together using the attachment means
in proximity to one end, clamping the lock of hair;
[0034] e) lift the second sheet away from the lock of hair so as to
render it accessible; and
[0035] f) apply the product to at least part of the isolated lock
of hair.
[0036] The attachment means to clamp the hair can include, for
example, a clamp device or a hook and loop fastener arrangement as
described above. After taking up a lock of hair, it can be isolated
between the two sheets in its entirety or a number of smaller locks
can be selected from this first lock of hair, retaining only one in
two of the smaller locks for example.
[0037] After attaching the two sheets together by clamping the lock
of hair, the combination of two sheets can be slid along the
isolated lock of hair to position them at the desired distance from
the scalp.
[0038] The product can be applied to the lock of hair from the
upper end of the isolated lock of hair.
[0039] After applying the product, the two sheets can be taken off
the hair by sliding them along the lock of hair, from the upper end
of the lock of hair to the tip. The lock of hair can then be
squeezed out to scrape off the excess product to prevent the
product from touching the rest of the hair before rinsing. By
removing the excess product, subsequent rinsing of the hair is also
facilitated.
[0040] The product is, for example, a coloring and/or decoloring
product.
BRIEF DESCRIPTION OF THE DRAWINGS
[0041] The invention will become further apparent from the
following detailed description, particularly when considered in
conjunction with the drawings in which:
[0042] FIG. 1 illustrates a perspective view of a first embodiment
of a device to isolate a lock of hair according to the
invention;
[0043] FIG. 2 is a sectional view of the first embodiment of the
device according to the invention;
[0044] FIGS. 3 to 5 illustrate different steps in a process for
application of a hair product using the device according to the
invention; and
[0045] FIG. 6 illustrates a second embodiment of a device to
isolate a lock of hair according to the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0046] Examples of a device to isolate a lock of hair from a head
of hair will now be described with reference to FIGS. 1 to 5. The
device includes a first sheet 10 and a second sheet 20, which are
separate from each other.
[0047] By way of example, each of the sheets is preferably made of
plastic, more preferably the sheets are made of polyolefin.
Furthermore, the two sheets are preferably transparent so as to
enable the user to see the isolated lock of hair when the device is
arranged on the hair. In addition, the sheets 10 and 20 are
flexible so as to adapt to the shape of the hair on which they are
arranged and so as not to unduly bother the person on which they
are placed.
[0048] In the illustrated example, the two sheets are rectangular
in shape, however other shapes could be used. By way of example,
the sheets can have a length of between 10 and 30 cm, for example
10 cm, and a width of between 5 and 15 cm, for example 5 cm. They
are also preferably of limited thickness, for example on the order
of 30 .mu.m, which gives them their flexibility.
[0049] The first sheet 10 includes a first end 11 corresponding to
one of its widths and a second end 12, opposite the first, which
corresponds to the other of its widths. The second sheet 20 also
includes a first end 21 corresponding to one of its widths and a
second end 22, opposite the first, which corresponds to the other
of its widths.
[0050] The two sheets 10 and 20 are independent of each other but
are intended to be attached together over the lock of hair to be
isolated by means of attachment 30 and 31.
[0051] For this purpose, the first sheet 10 includes, at its first
end 11, a flexible strip 30 equipped with loop elements. The strip
30 is preferably arranged over the full width of the sheet 10 to
which it is glued or welded for example. The second sheet 20 also
includes, at its first end 21, a flexible strip 31 equipped in this
instance with hook elements. Here again, the strip 31 is preferably
arranged over the full width of the sheet 20 to which it is glued
for example.
[0052] The term "hook" is not to be construed in a limitative sense
and encompasses double-hook ends or spade ends. Similarly, the term
"loop" is not to be interpreted in a restrictive manner, and
encompasses open or closed loops. Thus, the strips 30 and 31
incorporate counterpart means of attachment which are spread over
their surface and which are capable of forming a mechanical
attachment when joined. The hooks and loops are capable of
cooperating with each other, with at least some of the hooks
engaging in the loops. The loop and hook elements are marketed, for
example, in the form of strips under the trademark VELCRO.RTM. and
are widely used as means of attachment, with the hooks being made
for example by molding of plastic and the loops being formed by a
woven or non-woven fabric.
[0053] The device just described can be used for example to apply a
coloring product to an isolated lock of hair.
[0054] For this purpose, the user first selects the lock of hair to
which the product is to be applied and arranges the first sheet 10
under this lock of hair. In the example illustrated in FIG. 3, this
sheet is placed in a manner such that the attachment strip 30 is
located at the upper end of the lock of hair, and in the example
shown, close to the scalp. Also, the strip 30 is arranged on the
side facing the lock of hair to be isolated.
[0055] As illustrated in FIG. 4, the user then places the second
sheet 20 on the isolated lock of hair over the first sheet, placing
the second strip 31 over the first strip, on the side facing the
lock of hair to be isolated.
[0056] The user can then exert light pressure on the sheets 10 and
20, at the level of strips 30 and 31, so that the hooks on the
second strip 20 engage with the loops on the first strip 10,
passing through the lock of hair and thereby attaching the two
strips together and to the lock of hair.
[0057] If necessary, the user may slide the two-sheet assembly thus
attached to the isolated lock of hair, in particular so as to
position them at the desired distance from the scalp.
[0058] The second ends 12 and 22 of the sheets are free with
respect to each other, the user simply has to separate the second
sheet from the lock of hair by lifting it by its second end 22 in
order to apply the product to the lock of hair. The user then
applies the product, for example by means of a brush, starting from
the upper end of the lock of hair (or the upper end between the
sheets), and spreading the product towards the tips of the
hair.
[0059] Given that the edge delineated by the attachment strips 30
and 31 is rectilinear and the attachment means 30 and 31 clamp the
lock of hair sufficiently to prevent the product from migrating
beyond the attachment strips, the starting point of the lock of
hair is colored with a clear demarcation line.
[0060] In addition, as the sheets 10 and 20 are impermeable to the
product, the remainder of the hair is perfectly isolated.
[0061] The whole of the sheet 20 arranged above the lock of hair
can then be replaced on the treated lock of hair for the holding
period during which the coloring product acts on the lock of
hair.
[0062] After the holding period, the user can remove the two sheets
by pulling on their second end 12 and 22 in the direction of the
arrow shown in FIG. 5. By moving the sheets 10 and 20 down to the
tip of hair, the lock of hair is then squeezed out as the strips 30
and 31 scrape off the excess product. The product is thus prevented
from touching the rest of the hair and subsequent rinsing is also
facilitated.
[0063] When they have been completely removed from the hair, the
two sheets 10 and 20 can then be cleaned, for example with water,
enabling them to be used a second time.
[0064] In the example illustrated, the sheets are attached in
proximity to the scalp, but they can of course be attached a
variable distance from the scalp in order to obtain particular
effects.
[0065] In a variant not illustrated, the sheets can be trapezoidal
in shape, with the first ends 11 and 21 of the sheets incorporating
the attachment means being neither parallel to the second ends 12
and 22 nor perpendicular to the other edges of the sheets. By
arranging the sheets in a manner such that the second ends 12 and
22 are aligned with the tips of the lock of hair, the attachment
strips 30 and 31 are then arranged obliquely on the lock of hair.
Colored locks of hair having an oblique upper demarcation can thus
be readily obtained.
[0066] FIG. 6 illustrates a second embodiment of a device to
isolate a lock of hair using the same reference numbers as the
first embodiment incremented by 100.
[0067] This second embodiment differs from the first by the means
used to attach the two sheets together.
[0068] In this embodiment, the first sheet 110 includes at its
first end 111 a rigid strip 130 forming the first arm of a clamp,
and the second sheet 120 includes at its first end 121 a rigid
strip 131 forming the second arm of the clamp. The two arms 130 and
131 are connected at one of their ends by a hinge 132. The hinge
132 is a film hinge for example. It is configured so that the two
arms bear on each other (e.g., they are urged or biased toward each
other) so as to perform their clamping function. With this
arrangement, when the clamp or attachment device is in an attached
state the sheets are attached proximate their first ends, while in
an unattached state the sheets are coupled (via the clamp proximate
to the hinge) at only a corner of each of the sheets.
[0069] Each sheet 110 and 120 is for example glued at its first end
111 and 121 to the inside of each of the rigid arms 131 and
132.
[0070] To use this device, the user moves the two arms 131 and 132
apart and inserts the lock of hair to be isolated between the two
sheets. The clamp is then released thereby attaching to the lock of
hair. The product can then be applied as previously described.
[0071] In the foregoing detailed description reference is made to
preferred embodiments of the invention. Obviously, numerous
modifications and variations of the present invention are possible
in light of the above teachings. It is therefore to be understood
that, within the scope of the appended claims, the invention may be
practiced otherwise than as specifically described herein.
