Description
[0001] The present description relates to a Utility Model that
proposes an innovation in a tool for dyeing hair that may be used
both in professional and home settings.
[0002] Known in the prior art are a wide variety of hair dyeing
tools, among which there is a specific model that, in general
terms, includes a flexible structure similar to tweezers with a
small tray-like part on one of its ends and a brush-like part with
groups of bristle tufts on the other end.
[0003] This type of tool is used for applying highlights to hair;
its use provides, initially, application of a dye substance or the
like directly onto the brush bristles. After that, the tweezer-like
structure is pressed at the same time that a small volume of hair
is placed on the tray-like part.
[0004] After the tool is closed, it is passed along the group of
hair strands selected with the result that they come into contact
with the dye-impregnated bristles and are then suitably dyed.
[0005] Despite the fact that this type of tool is quite easy to
use, it has a basic aspect that is open to innovation with respect
to the configuration of the tray-like part, with its substantially
flat bottom and curved, short side walls that are basically
vertical, thus forming a corner in the area of intersection between
the bottom surface and the walls.
[0006] This type of configuration given to the tray-like part makes
proper positioning of the brush bristles difficult when it is time
for the dye to be applied to the hair, given that said bristles
tend to spread in a rather disorderly fashion when they are pressed
against the flat surface at the bottom of the tray.
[0007] Therefore, one of the objects of this Utility Model is to
provide a hair dyeing tool that is similar to the prior art in its
general structure, with devices shaped like tweezers, a tray, and a
brush. The innovative tool differs from the conventional model in
that its tray-like part has, in contrast to the model currently in
use, a bottom surface essentially rounded in the longitudinal
direction of the part, thus creating a continuous, curved surface
that also includes the side walls of said part.
[0008] The innovation introduced in said tray-like part allows the
brush bristles to be positioned so as to converge toward the middle
of the brush when pressed against it. This allows the bristles to
form a tunnel-like space along the brush, through which the hair to
be dyed must pass.
[0009] The space between the bristles provides full coverage of the
hair, thus improving the conditions of dye application on the hair
and resulting, consequently, in better dye application.
[0010] The hair dyeing tool constituting an object of this Utility
Model also proposes a variant with two end walls that act so as to
better guide the volume of hair strands through a tray-shaped
passage.
[0011] The tool in question shall be described in detail with
reference to the drawings below wherein:
[0012] FIG. 1 depicts a perspective view of the proposed tool, in
its neutral state;
[0013] FIG. 2 depicts a side view of said tool, in its neutral
state;
[0014] FIG. 3 depicts a schematic view indicating the position of a
given volume of hair (in cross-section) over the tray-like
part;
[0015] FIG. 4 depicts a first step of closing the tool, wherein its
brush is pressed against the tray-like part, as is schematically
indicated by the arrows "A";
[0016] FIG. 5 depicts the step following that of FIG. 4, wherein,
due to the continuing closing of the tool as indicated by the
arrows "A", the brush bristles come into contact with the curved
surface of the tray-shaped piece and are then deflected as
indicated by the arrows "B", so as to converge, thus forming the
tunnel-like space that completely surrounds the volume of hair to
be dyed; and
[0017] FIG. 6 depicts a variant of the tool in question.
[0018] According to the figures listed above, the hair dyeing tool
in question is referenced, generally, by the number 1 and comprises
a flexible structure that is similar to tweezers 2, which has a
piece that is similar to a small tray 3 at the end of one of its
arms, and a piece similar to a brush 4 at the end of its other arm,
including on its lower face groups of bristle tufts 5, 6, and 7 of
different lengths.
[0019] The tool 1 is constructed to be handled such that when the
tweezer-like structure 2 is squeezed, the tray 3 and the brush 4
come together, as depicted schematically in FIGS. 4 and 5.
[0020] The groups of bristle tufts 5, 6, and 7 are developed such
that the group of bristle tufts 5 has bristles of a given length,
which is longer than the length of the two other groups of bristle
tufts, i.e., the groups of bristle tufts 6 and 7, whereas, in turn,
said group of bristle tufts 6 has shorter bristle length compared
to the group of bristle tufts 7.
[0021] The tray 3 has a raised, angled lateral end 8 and an
opposing end 9 which follows the general surface level of the tray
3, as depicted in FIGS. 1, 2, 3, 4, and 5.
[0022] The lateral end 8 of the tray 3 has a U-shaped opening 10,
whereas another U-shaped opening 11 (with a wider mouth) is
provided on the opposite end 9.
[0023] The tool 1 in question, in contrast to what is seen in
similar tools belonging to the prior art, has, with regard to its
tray-like part 3, a special configuration on the surface of its
bottom wall 12, which is curved and continuous with the lateral
walls 13.
[0024] The surface of the bottom wall 12 which is part of the tray
3 is implemented so as to serve as the center point for the
bristles included in the groups of the bristle tufts 5 and 7 to go
in opposite directions against one another when the brush 4 is
pressed against the tray 3 as is depicted in FIG. 5 and according
to what is indicated by the arrows "B" in said figure.
[0025] The orientation given to the bristles of the groups of
bristle tufts 5 and 7 creates a space E that is similar to a tunnel
through which hair strands C are forced to pass during the dyeing
process.
[0026] The space E, thus defined, envelops the entire volume of
hair strands C that is being dyed, thus improving the conditions of
dye transfer previously applied to the bristles of the brush 4 and
going from them to the hair strands C.
[0027] The creation of the space E is only possible due to the
curve incorporated into the surface of the bottom wall 12 of the
tray-shaped part 3, when the brush 4 is pushed against it, causing
the end of the bristles of the groups of bristle tufts 5 and 7 to
move such that they come together.
[0028] The curvature of the surface of the bottom wall 12 is
defined so as to link the center line of said wall (indicated in
the drawing as a dashed line present only in FIGS. 1 and 6, and
referenced as 12a) in a constant curved line, to the ends of walls
13, thus creating a sliding surface for the bristles of the two
groups of bristle tufts 5 and 7.
[0029] The present utility model also includes, as depicted in FIG.
6, a variant of the model of the tool 1 depicted in FIGS. 1 through
5, wherein the structure provided in an angled, raised lateral end
8 of the tray 3 is also provided on the opposite end of said part,
thereby creating a configuration that promotes greater dye
retention in the space circumscribed by the tray 3.
