Description
TECHNICAL FIELD
[0001] The present invention relates, in general, to mascara
brushes and, more particularly, to a mascara brush in which a
bristle part for applying mascara to eyelashes and a comb part for
tidying the eyelashes are formed around the brush body through a
double injection molding process, thus simplifying manufacturing
equipment and manufacturing and assembling processes, thereby
reducing production costs and enhancing workability and
productivity.
BACKGROUND ART
[0002] Generally, a mascara applicator is used to apply various
colors of mascara, which is one kind of cosmetic for women, to
eyelashes to beautify the eyes. Typically, such a mascara
applicator includes a container, which contains mascara therein,
and a handle, which is used when opening or closing the container.
The mascara applicator further includes a brush bar, which extends
from the handle downwards, and a brush, which is provided on the
brush bar. To use the mascara applicator, the mascara is applied to
the brush in a process of coupling and removing the handle to and
from the container.
[0003] Particularly, the mascara brush can conduct various
functions, for example, a volumizing function (an effect of making
eyelashes appear abundant), a curling function (an effect of
curling the ends of the eyelashes upwards), a lash lengthening
function (an effect of making the eyelashes appear long) and a
cleaning function (an effect of preventing the eyelashes from
aggregating), according to the length and shape of bristles of the
mascara brush.
[0004] Typically, mascara brushes are manufactured through a
process in which brush bristles having predetermined lengths are
placed between two strands of wire and the wires are twisted
several times such that the cross-section thereof has various
shapes, for example, a circular shape, a triangular shape or a
sectorial shape, based on the center axis of the wires. According
to the shape of the cross-section of the brush, it can exhibit a
volumizing, curling, lash lengthening or cleaning effect.
[0005] Such a mascara brush must have a superior combing effect to
evenly apply mascara, which has a relatively high viscosity, to
eyelashes and prevent the eyelashes from becoming tangled or
adhered to each other by the mascara. In the case of the
conventional mascara brush, because the bristles are arranged in a
spiral shape by twisting the wires, a relatively large amount of
mascara can be applied between the bristles, so that the effect of
volumizing the eyelashes is ensured. However, due to the viscosity
of the mascara, the eyelashes may be tangled or adhered to each
other. In this case, a separate eyelash tidying device is required
to tidy the eyelashes, or, alternatively, a user may have to
reapply mascara after removing the originally applied mascara.
[0006] In an effort to overcome the above problems, a mascara brush
having a tidying brush unit was proposed.
[0007] FIG. 1 is an exploded front view showing a conventional
mascara brush having an applying brush unit and a tidying brush
unit.
[0008] FIG. 2 is a front view showing another conventional mascara
brush.
[0009] As shown in the drawings, the mascara brush includes the
applying brush unit 3, which is a means for applying mascara to
eyelashes. To manufacture the applying brush unit 3, bristles 31,
each of which has a predetermined length, are perpendicularly
interposed between parts of a wire, which is bent at the
intermediate position thereof and is thus folded in half.
Thereafter, the folded parts of the wire are twisted a
predetermined number of times. Then, the bristles 31 are radially
fastened to the wire shaft 21, which is formed by twisting the
wire.
[0010] The applying brush unit 3 has a cut part, which is formed by
cutting some of the bristles 31, which are perpendicularly fastened
to one side of the wire shaft 21. The applying brush unit 3, which
is manufactured through the above-mentioned process, is integrally
coupled to the lower end of a brush body.
[0011] The tidying brush unit 4 is a means for tidying the
eyelashes, to which mascara is applied by the applying brush unit
3. The tidying brush unit 4 includes a comb 42, which protrudes
outwards from a support member 41.
[0012] The support member 41 serves to fasten the comb 42 to the
cut part 32 of the applying brush 3, and the circumference thereof
is equal to that of the brush body. Furthermore, the length of the
support member 41 is equal to or slightly greater than the length
of the wire shaft 21, which protrudes from the lower end of the
brush body, such that the support member 41 can be integrally
coupled to the applying brush unit 3.
[0013] The support member 41 has in the upper end thereof an insert
hole 44, through which the wire shaft 21 is inserted so as to be
integrally coupled to the support member 41. An insert seat 43 is
formed in the lower end of the support member 41, so that the lower
end of the wire shaft 21 is inserted into and fastened to the
insert seat 43 of the support member 41. Furthermore, because the
support member 41 must be disposed on the cut part 32 of the
applying brush unit 3, the upper end and the lower end of the
support member 41, having the insert hole 44 and the insert seat
43, are supported by a side bar 45. Thus, the support member 41 has
a U shape, and the cross-section thereof has a sectorial shape
corresponding to the shape of the cut part 32.
[0014] The comb 42 perpendicularly protrudes from the
circumferential outer surface of the side bar 45 of the support
member 41 to thus form a single comb, and serves to comb the
eyelashes. In detail, the comb 42 is arranged linearly and
perpendicularly extends from the side bar 45 to lengths
corresponding to the lengths to which the bristles 31 protrudes
from the wire shaft 21 of the applying brush unit 3. The teeth of
the comb 42 are made of synthetic resin, which is the same material
of the support member 41, and each comb tooth is thicker and harder
than each bristle 31 of the applying brush unit 3. The teeth of the
comb 42, which are linearly arranged, are spaced apart from each
other at regular intervals. Therefore, the tidying brush unit 4 has
a shape similar to that of a typical straight comb.
[0015] However, in the conventional mascara brush, the applying
brush unit 3 and the tidying brush unit 4 are manufactured through
separate processes and are subsequently assembled with each other.
Therefore, labor and equipment are required to conduct the
additional assembly process, thus incurring additional costs.
[0016] Furthermore, the manufacture of the applying brush unit 3
requires a complex manufacturing process, in which a large number
of bristles having predetermined lengths is held between parts of
the wire and the wire is thereafter twisted in a spiral shape such
that the bristles 31 are radially fastened to the wire shaft 21. In
addition, because the tidying brush unit 4 is manufactured through
a separate injection molding process, separate molding equipment is
required. Therefore, the conventional mascara brush has problems of
increased production costs and reduced productivity, attributable
to the complex production line.

BEST MODE FOR CARRYING OUT THE INVENTION
[0039] Hereinafter, preferred embodiments of the present invention
will be described in detail with reference to the attached
drawings.
[0040] FIGS. 3 and 4 are front views, plan views and side views of
mascara brushes according to a first embodiment of the present
invention. As shown in the drawings, the mascara brush according to
the first embodiment includes a bristle part 120, which is formed
by integrally injection-molding a cylindrical brush body 110 and
bristles 121, which are formed around the brush body 110 to apply
mascara to eyelashes, and a comb part 130, which tidies the
eyelashes and is formed through a double injection molding process
such that part of the comb part 130 is embedded in the brush body
110.
[0041] The brush body 110 has an approximately cylindrical shape,
and is coupled to a brush handle (not shown). A coupling boss 111,
through which the brush body 110 is coupled to the brush handle, is
provided on one end of the brush body 110.
[0042] The bristle part 120 and the comb part 130 are configured
such that the many bristles 121 and comb teeth 131 are arranged
around the circumferential outer surface of the brush body 110. The
bristles 121 are integrally formed with the brush body 110. The
comb part 130 is formed by injection molding using material which
is different from that of the brush body 110.
[0043] As such, an injection molding method using two kinds of
materials is called `double injection molding`. Below, the double
injection molding will be explained in detail. In such double
injection molding, using two kinds of resins or two colors of
resins, and using two injection molding apparatuses and injectors,
which are constructed such that a rotating device is coupled to a
driving plate, or cores or slide structures, a first intermediate
product is formed using a mold that can be used for double
injection molding, and a second resin is charged into a space
defined between the first intermediate product and a second cavity,
thus forming a final product.
[0044] In such double injection molding, because the first and
second cavities are precisely defined, restriction in shape is
reduced and various designs are realized, so that it can be applied
to various products. Furthermore, the injection molding is
conducted through a single process, unlike the typical injection
molding process, in which two kinds of intermediate products are
formed through two steps and the intermediate products are
thereafter produced into a final product by a secondary process,
such as welding or coating. Accordingly, there are advantages in
that the production cost is reduced, and various kinds of products
can be produced.
[0045] Furthermore, in the present invention, circular brush rows,
each of which is defined by radially forming bristles 121 of the
bristle part 120 and a comb tooth 131 or comb teeth of the comb
part 130 around the brush body 110, are repeatedly arranged on the
brush body 110 in the longitudinal direction, thus completing the
mascara brush.
[0046] Here, as a molding method used to radially form the bristles
121 of the bristle part 120 and the comb teeth 131 of the comb part
130 around the brush body 110, an injection molding method may be
used.
[0047] The injection molding method is a well known technique, and
is one molding method that has been widely used. An example of the
injection molding method used in the present invention will be
briefly explained.
[0048] First, micro molds (not shown) are provided in a shape in
which each micro mold surrounds the circumferential outer surface
of the brush body 110. Thereafter, the bristles 121 and the comb
131 are radially formed around the circumferential outer surface of
the brush body 110 by injection molding.
[0049] Here, the micro molds (not shown) are stacked on top of one
another around the brush body 110 in the longitudinal direction so
that the bristles 121 and the comb teeth 131 can be formed at one
time. Furthermore, the arrangement of the bristles 121 and the comb
teeth 131 can be easily changed depending on the shape of the
mold.
[0050] As described above, the bristle part 120 and the comb part
130 are formed using different materials. In detail, preferably,
the bristle part 120 is made of soft material such that the
bristles 121 thereof are easily bent and relatively soft, and is
thus able to conduct the same function as a conventional bristle
brush. The comb part 130 is preferably made of relatively hard
material, such that the comb teeth 131 of the comb part 130 are not
easily bent and are relatively hard, and thus is able to conduct
the same function as a typical comb used for tidying the
eyelashes.
[0051] As shown in FIG. 3, the comb part 130 may be configured such
that a center comb support part 133 is formed at the center in the
brush body 110 and one row of comb teeth 131 radially extends from
the center comb support part 133.
[0052] Alternatively, as shown in FIG. 4, the comb part 130 may he
configured such that a side comb support part 135 is formed in the
outer surface of the brush body 110 and one row of comb teeth 131
radially extends from the side comb support part 135.
[0053] As such, FIGS. 3 and 4 illustrate examples in which the
bristle part 120 and the comb part 130 are formed such that the
bristles 121 and the comb teeth 131 are arranged around the brush
body 110, and one row of comb teeth 131 of the comb part 130 is
oriented in one direction.
[0054] FIG. 5 is plan views illustrating modifications of FIG. 3.
As shown in FIG. 5, the comb part 130 may be configured such that
one row of comb teeth 131 radially extends from the outer surface
of the brush body 110, or, alternatively, several rows of comb
teeth 131 may be formed on the brush body 110.
[0055] FIGS. 6 and 7 are plan views illustrating mascara brushes
according to a second embodiment of the present invention. As shown
in the drawings, in the second embodiment, a bristle part 120 and a
comb part 130 are configured such that bristles 121 and comb teeth
131 are arranged around a brush body 110 and are oriented in radial
directions, wherein the comb part 130 extends from the brush body
110 in two opposite directions.
[0056] FIGS. 8 and 9 are plan views illustrating mascara brushes,
according to a third embodiment of the present invention. As shown
in the drawings, in the third embodiment, a bristle part 120 and a
comb part 130 are configured such that bristles 121 and comb teeth
131 are arranged around a brush body 110 and are oriented in radial

110 in four directions spaced apart from each other at regular
angular intervals.
[0058] As can be appreciated from the first through fourth
embodiments, the brush body 110 may have a polygonal cross-section
having three or more angles, as an alternative to a circular
cross-section.
[0059] If the brush body 110 has a polygonal cross-section, a
mascara brush may be constructed such that comb parts 130 are
formed on the corners of the brush body 110 and the bristle parts
120 are formed on the faces of the brush body 110. In this case,
preferably, the length of the comb teeth 131 of the comb part 130,
which are formed at the corners of the brush body 110, is shorter
than in the mascara brush having the circular brush body 110.
[0060] Alternatively, the brush body 110 may have an elliptical
cross-section. As a further alternative, the brush body 110 may be
designed to have various other shapes.
[0061] The mascara brush having the above-mentioned structure is

according to the fifth embodiment includes a bristle part 120,
which is formed by integrally injection-molding a cylindrical brush
body 110 and bristles 123, which are formed around the brush body
110, to apply mascara to eyelashes, and a comb part 130, which
tidies the eyelashes and is formed through a double injection
molding process such that part of the comb part 130 is embedded in
the brush body 110.
[0064] Here, the bristle part 120 is formed such that the bristles
123 are relatively thin, and each bristle 123 has branches so that
it thus has a snowflake shape, thus increasing the ability to
absorb mascara. The comb part 130 is made of relatively hard
material, such that the comb teeth 131 thereof have strength
appropriate to conduct an eyelash tidying operation.
[0065] As shown in FIG. 12, the comb part 130 may be configured
such that a center comb support part 133 is formed at the center in
the brush body 110 and such that at least one row of comb teeth 131
extends from the center comb support part 133.
[0066] Alternatively, as shown in FIG. 13, the comb part 130 may be
configured such that a side comb support part 135 is formed in the
outer surface of the brush body 110 and at least one row of comb
teeth 131 extends from the side comb support part 135.
[0067] As such, FIGS. 12 and 13 illustrate examples in which the
bristle part 120 and the comb part 130 are formed such that the
bristles 123 and the comb teeth 131 are arranged around the brush
body 110 and are oriented in radial directions, and the one row of
comb teeth 131 of the comb part 130 is oriented in one
direction.
[0068] FIG. 14 is plan views illustrating modifications of FIG. 12.
As shown in FIG. 14, the comb part 130 may be configured such that
from one to five rows of comb teeth 131 radially extend from the
center comb support part 133 in one direction.
[0069] FIGS. 15 and 16 are plan views of mascara brushes, according
to a sixth embodiment of the present invention. As shown in the
drawings, in the sixth embodiment, a bristle part 120 and a comb
part 130 are configured such that bristles 123 and comb teeth 131
are arranged around a brush body 110 and are oriented in radial
directions, wherein the comb part 130 extends from the brush body
110 in two opposite directions.
[0070] FIGS. 17 and 18 are plan views illustrating mascara brushes
according to a seventh embodiment of the present invention. As
shown in the drawings, in the seventh embodiment, a bristle part
120 and a comb part 130 are configured such that bristles 123 and
comb teeth 131 are arranged around a brush body 110 and are
oriented in radial directions, wherein the comb part 130 extends
from the brush body 110 in three directions spaced apart from each
other at regular angular intervals.

according to an eighth embodiment of the present invention. As
shown in the drawings, in the eighth embodiment, a bristle part 120
and a comb part 130 are configured such that bristles 123 and comb
teeth 131 are arranged around a brush body 110 and are oriented in
radial directions, wherein the comb part 130 extends from the brush
body 110 in four directions spaced apart from each other at regular
angular intervals.
[0072] As can be appreciated from the fifth through eighth
embodiments, the brush body 110 may have a polygonal cross-section
having three or more angles, or an elliptical cross-section.
[0073] If the brush body 110 has a polygonal cross-section, a
mascara brush is preferably constructed such that comb parts 130
are formed on the corners of the brush body 110 and the bristle
parts 120 are formed on the faces of the brush body 110. In this
case, preferably, the length of the comb teeth 131 of the comb part
130, which are formed at the corners of the brush body 110, is
shorter than in the mascara brush having the circular brush body
110.
[0074] Of course, the cross-sectional shape of the brush body 110
is not limited to a circular shape, a polygonal shape or an
elliptical shape, and the design of the cross-section thereof can
be easily changed in a process of producing products.
[0075] The mascara brush having the above-mentioned structure is
