Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the full benefit and priority of
pending provisional patent application No. 61/454,482, filed Mar.
18, 2011, entitled "Swirl Brush and Manufacturing Method". The
entire contents of said application are incorporated herein by
reference.
BACKGROUND OF THE INVENTION
[0002] The type of hair used in cosmetic applicators and makeup
brushes may differ depending on its intended use. For example,
natural hairs may be better suited for transferring certain
cosmetic products from a container to the skin, while synthetic
hairs may be better suited for blending the cosmetic product on the
skin. For mineral based makeup, such as powders, blushes, bronzers,
etc., it may be desired to use synthetic fibers to apply the makeup
and natural fibers to blend. For example, a blush may be applied to
the user's cheekbone with the synthetic fibers and the blush may
then be blended on the cheekbone with the natural fibers. For pan
or pressed products such as pressed powders, eye shadows, etc., it
may be desired to use natural fibers to apply and synthetic fibers
to blend. For example, eye shadow may be applied with the natural
fibers and then blended with synthetic fibers. In addition, certain
other properties of brush hairs, such as stiffness, thickness,
length, etc., may affect the quality and nature of their use in
cosmetic brushes.
[0003] Traditional cosmetic brushes are comprised of a single type
of hair. As such, the tasks of application and blending require the
use of two separate brushes. Certain brushes exist in the prior art
that incorporate a blend of natural and synthetic hair; however,
oftentimes blending one type of hair with another simply dilutes
the beneficial qualities of each type of hair. Providing separate
brushes within the same ferrule can be useful but may require
reorientation of the brush in the user's hand for effective use of
the separate fibers. Thus, there is a need for a cosmetic brush
that is capable of incorporating different types of brush hairs
while maintaining the separate qualities of the different brush
hairs and providing the ability to seamlessly switch between
different tasks such as application and blending.
[0004] There is also a need in the art for improvements relating to
brushes that have hair of different colors, but not necessarily
other different properties (natural or synthetic).
BRIEF SUMMARY OF THE INVENTION
[0005] An object of the invention is to provide a method of making
brush heads. According to one aspect of the invention, a method
comprises making elongate bundles of brush hair held by flexible
adhesive base at one hair end. According to another aspect of the

the invention, the elongate bundles are each comprised of a
different type of brush hair.
[0006] According to another aspect of the invention, the elongate
bundles are each comprised of brush hair having at least one
dissimilar property. According to another aspect of the invention,
the dissimilar property between the brush hairs may be the average
length of the brush hairs. According to another aspect of the
invention, the dissimilar property between the brush hairs may be
the color of the brush hairs. According to another aspect of the
invention, the dissimilar property between the brush hairs may be
the thickness of the brush hairs.

GENERAL OUTLINE
[0090] This disclosure includes discussions regarding three brush
head configurations and the methods for manufacturing same. These
include: [0091] A "Swirl Head" manufacturing process, hereinafter
also referenced as the First Manufacturing Process (see FIGS. 1-10)
[0092] A "Spotted Print" manufacturing process, hereinafter also
referenced as the Second Manufacturing Process (see FIGS. 11A-11H)
[0093] A "Spiral Design" manufacturing process, hereinafter also
referenced as the Third Manufacturing Process (see FIG. 12)
[0094] The First Manufacturing Process
[0095] FIGS. 1A through 1P depict an embodiment of a first
multistep brush head manufacturing method according to one aspect
of the present invention for making a brush head with two types of
brush hairs or fibers in a swirl configuration with respect to one
another in the same ferrule. In various embodiments, the two types
of brush hairs are selected or blended from a wide range of natural
hairs (e.g., goat, pony, sable, and the like), synthetic hairs well
known in the art (e.g., nylon, polyester, Taklon fiber,
polybutylene terephthalate or polyamide), or blends of synthetic
fibers. These brush hairs may vary in characteristics such as
stiffness (stiffer vs. more flexible), hardness (harder vs.
softer), or bristle end structure (for example, a simple cut end
vs. a pointed end vs. a split end). Synthetic brush hairs may be
grooved or roughened. The different types of brush hair may be a
single fiber or may be a blend or fibers or colors.
[0096] FIG. 1A shows steps 1-5 of a multistep manufacturing
process. In Steps 1 and 2, as denoted in FIG. 1A, a first type of
brush hair 120 is sorted and blended according to conventional
methods.
[0097] In Step 3, the sorted and blended brush hair 120 is combed
with a combing instrument 210, in preparation for placement in a
bundle 220, as shown in Steps 4 and 5, with the hairs roughly
parallel to one another. At Step 6 (FIG. 1-B) there is weighing
with a scale 230.
[0098] As shown in FIG. 1-C, at Step 7, the depicted manufacturing
method departs from conventional methods. As denoted in FIG. 1C, a
first type of brush hair 120 is placed into a mold 240. The mold
240 has an adjustable wall 245, the position of which can be
secured by a tightening arm 247 to form a secure fit around the
bundle, ensuring that the brush hair 120 is held in place. The wall
245 of the mold also defined a peripheral wall which, in
combination with the ends of the brush hairs, defines an upwardly
directed cavity. In Step 8, as denoted in FIG. 1D, a layer of
adhesive 250 is poured into this cavity, atop the bundle of the
first type of brush hair 120 over an area of hair ends in the mold
240 as the bundle is held in the mold 240. A suitable adhesive
known in the art is Max-Bond Glue 888.
[0099] In Step 9, as denoted in FIG. 1E, the glue 250 begins to dry
while infiltrating downward into the first type of brush hair 120
between the hair ends. As a result, the individual brush hairs are
glued together by a layer of adhesive forming a bundle base 126 at
one of the ends of the hairs, which may be referred to as their
base ends (or secured ends).
[0100] In Step 10, as denoted in FIG. 1F, the mold 240 holding the
first type of brush hair 120 and partly dried adhesive is fed
through a slicing machine 270. The slicing machine 270 has a lever
275 that holds a blade (not shown) capable of slicing through the
adhesive base 126 across the width of the mold, for at least the
depth penetrated by the adhesive. FIG. 1G shows a bundle of brush
hair still in the mold 240 after it has been sliced along cut lines
271 into a number of pieces.
[0101] As shown in FIG. 1H, a plurality of first hair slices 122
are removed from the bundle. As may be seen, they are elongate and
substantially planar as viewed in FIG. 1H. As depicted in FIG. 1H,
the first hair slices 122 have a thickness of approximately 5 mm
and a slice base 124 formed of adhesive 250. In various
embodiments, the hair slices may have a thickness of approximately
2 mm to 5 mm, and the brush hairs may have average lengths of
approximately 20 mm to 90 mm. This first hair slice could also be
referenced as a first hair strip, including a plurality of elongate
flexible bristles being generally aligned along their lengths, each
of said bristles having two opposing ends, one end being an
application end and the other end being a secured end, said first
hair strip itself also comprising an elongate strip base 124 which
interconnects said secured ends. The elongate flexible bristles
within the slice could be said to have their axes oriented
generally transverse to the elongate length or axis of the slice,
although elongate slice is not necessarily straight, but
curved.
[0102] In Step 11, as denoted in FIG. 1-I, the slice of brush hair
122 is subjected to a thinning process before the adhesive 250 of
the slice base 124 completely dries. As such, the slice 122 is fed
through an opening 285 in a hair press 280 until it reaches a
desired thickness. For example, the press 280 may feed the slice
122 between rollers separated by the desired thickness. In the
present embodiment, the slice 120 is pressed until it is
approximately 4 mm in thickness.
[0103] Drying time varies based on how large the brush is, but
typically the time is 2-5 hours,
[0104] As illustrated in FIG. 1J, the thinning process may create a
concave curvature in the base 124 such that the brush hairs
opposite the slice base fan out along the length of the slice 122.
Nevertheless, they are elongate and substantially planar as viewed
in FIG. 1J.
[0105] Steps 1A through 1L are then carried out with a second type
of brush hair 130 to create a second slice 132 of brush hair, as
shown in FIG. 1K. Depending on the desired functions and features
of the resultant brush head, the second type of brush hair could be
selected to differ from the first type of brush hair in length,
texture, stiffness, hardness, and/or structure. For example, either
or both of the first or second sets of brush hairs may be subjected
to an additional texturizing step at any point in the process. For
example, the ends of the brush hairs may be tapered or split with a
razor to create a feathered effect.
[0106] In the illustrated embodiment, the brush hairs in the second
slice 132 are generally longer than the brush hairs in the first
slice. For example, the brush hairs in the first slice 122 have an
average length of approximately 53 mm, while the average length of
the brush hairs in the second slice is approximately 60 mm.
Therefore, the average difference in length is approximately 7 mm.
In other embodiments, the average difference in length between the
first set and second set of brush hairs may be greater or less than
7 mm, depending on the size and intended use of the brush. The
desired difference in length may also vary depending on the
respective properties (e.g., stiffness, thickness, etc.) of the
first and second types of brush hair. Alternatively, in other
embodiments, the first and second sets of brush hairs may be
approximately the same length.
[0107] In Step 12, the first and second slices of brush hair to be
combined in a brush head are assembled. In the embodiment shown in
FIG. 1K, the first slice of brush hair 122 is stacked on top of the
second slice of brush hair 132 in planar contact such that a
two-layer elongate strip of hair is provided.
[0108] In Step 13, as denoted in FIG. 1L, the two-layer elongate
strip of hair is rolled up from one end to the other, while keeping
the glued bases 124 and 134 of the first and second hair slices
122, 132, substantially aligned (as illustrated in FIG. 1M), to
form a brush head 110. In Step 14(a), as denoted in FIG. 1N, the
brush head 110 is tied at its base with a cord 260.
[0109] At this point in the manufacturing process, the next step
will vary depending on the desired shape of the brush head. In
various embodiments where a domed or rounded brush head is desired,
the brush head 110 may then be subjected to a doming and shaping
process, which is depicted from Step 14(b) in FIG. 1N through Step
14(e) in FIG. 1-O.
[0110] The Doming and Shaping Process of Steps 14(b)-14(e)
[0111] In Step 14(b), as shown in FIG. 1N, the glued bases 124 and
134 are cut off of the brush head 110, forming a cut end 118
opposite an exposed end 116 of the brush head. In this way, the cut
end 118, along with the remaining portions of both the first slice
122 and the second slice 132, are free of adhesive.
[0112] In Step 14(c), as shown in FIG. 1-O, the brush head 110 is
placed into a shaping mold 265. The shaping mold 265 has an open
end 266 and a closed end 267. The open end 266 of the shaping mold
265 receives the exposed end 116 of the brush head, which situates
into the closed end 267 of the shaping mold 265. In Step 14(d), the
cord 260 is untied, allowing the brush hairs to conform to the
shape of the internal walls of the shaping mold 265 in Step 14(e).
In this step, the shaping mold 265 may be subjected to gentle
shaking or tapping in order to encourage the brush hairs into a
conforming position. In Step 15(a), as further denoted in FIG. 1-O,
the brush head 110 is then retied (or tied, in the case Steps 14(a)
through 14(e) are bypassed) at its base with the cord 260.
[0113] In the depicted embodiment of the present invention, the
interior of the closed end 267 of the shaping mold 265 is
substantially dome-like. However, in other embodiments, the
interior of the closed end 267 of the shaping mold 265 may take any
of a variety of other shapes. For example, the shaping mold may be
pointed, square, or any of a number of other shapes on the
interior. Accordingly, the brush head resulting from the shaping
step of these various shaping molds would be shaped
correspondingly.
[0114] Skipping Doming/Shaping Process
[0115] In various embodiments of the present invention, the brush
head will not be shaped as shown in Steps 14(a) through 14(e). In
this way, the process for making the brush head in these various
embodiments will therefore follow the rolling step (i.e., Step 13,
as shown in FIG. 1L) with the tying step (i.e., Step 15 or 15(a),
as shown in FIG. 1-O). For example, the brush head 300 shown in
FIGS. 5 and 6, as further described below, was manufactured
according to an embodiment of the present invention that bypassed
the shaping steps shown in Steps 14(a) through 14(e).
[0116] After Steps 14(a) through 14(e) are either used or bypassed,
as illustrated by FIGS. 1-O through 1Q, a cosmetic brush 100 is
then assembled using conventional methods. In Step 15(b), as
denoted in FIG. 1P, the brush head 110 is planted into a ferrule
140. Wrapping the head in a removable polypropylene sheet can help
this process as needed. As shown in FIG. 10, in Step 16, an open
end of the ferrule 140 is then attached to the glued end of the
brush head 110 using a ferrule press 290. Finally, in Step 17, a
handle 150 is attached to the ferrule 140 in any conventional
manner, such as crimping, with adhesive, or a combination of the
two, to create a finished cosmetic brush 100. The selection of the
ferrule 140 and the handle 150, as well as the means for attaching
the handle 150 to the ferrule 140, are known in the art.
[0117] The finished cosmetic brush 100 shown in FIGS. 2 through 4
is manufactured according to the above-described method. Rolling
the respective slices of differing hairs together results in a
swirl pattern in the brush head 110 comprised of the first slice
122 formed from the first type of brush hair 120 and the second
slice 132 formed from the second type of brush hair 130, all
secured by the ferrule 140. In the embodiment shown in FIG. 4, the
second slice 132 has been positioned to form the outer perimeter of
the brush head 110. In the alternative, the first slice 122 could
be positioned to form the outer perimeter.
[0118] One advantage of the finished cosmetic brush 100 over
brushes known in the art is that it incorporates the benefits of
both the first type of brush hair 120 and the second type of brush
hair 130 without diluting the properties of either as could happen
when conventionally blending the types of hairs and making a brush
head treating the blended hairs as a single type. When using the
brush 100, the second type of brush hair may be better suited for
applying a cosmetic powder, and the first type of brush hair may be
better suited for blending the cosmetic powder. In one embodiment,
the longer hair is natural hair, being more suited to pick up the
product, and the shorter hair is synthetic fiber, which is more
`slick` than natural or smooth so it works best with emollient
based make up.
[0119] With the cosmetic brush 100 with a swirled brush head 110 as
seen in FIGS. 2 through 4, the longer second type of brush hair
forming the outer circumference of the brush head can be used to
lightly apply the cosmetic powder without interference from the
first type of brush hair, which is recessed due to its shorter
length, thus providing discrete recessed portions. However, the
first type of brush hair can be brought in contact with the
application surface by applying slightly greater pressure on the
brush head. In this way, the first type of brush hair can be
accessed and used as desired for blending, without having to switch
cosmetic brushes or change the orientation of the user's grip on
the brush handle. Furthermore, unlike brush heads with a blended
distribution of different types of brush hairs, the properties of
the different brush hairs are not diluted in the swirled brush head
110, since the brush hairs of separate slices remain mostly
separated from one another.
[0120] Note that the "slices" or "strips" of hair can have glue
strip bases prior to final assembly, but can still be considered
"slices" or "strips" of hair even when installed and without the
glue bases.
[0121] Another finished cosmetic brush 300 manufactured according
to the above-described method is shown in FIGS. 5 and 6. This
cosmetic brush 300 comprises a swirled brush head 310 comprised of
a first slice 322 formed from a first type of brush hair 320 and a
second slice 332 formed from a second type of brush hair 330.
Unlike the brush head 110 in FIGS. 2 through 4, the brush hairs in
the first slice 322 are approximately the same length as the brush
hairs in the second slice 332.
[0122] Yet another finished cosmetic brush 340 manufactured
according to an embodiment of the present invention is shown in
FIGS. 7 and 8. Furthermore, another finished cosmetic brush 360
manufactured according to another embodiment of the present
invention is shown in FIGS. 9 and 10.
[0123] The Second Manufacturing Process (FIGS. 11A-H)
[0124] Reference is now made to FIGS. 11-A to 11-H, which describes
a "spotted print" manufacturing process, hereinafter also
referenced as the Second Manufacturing Process.
[0125] Generally described, this process includes taking various
slices of hair and overlaying them together in a different manner
than the "dual layer--rolled up" configuration of the First
Manufacturing Process described above. A core slice 430 (aka first
slice, aka first layer) is folded over itself to form a sort of
irregular core (see FIG. 11-A). As shown in FIG. 11-B, a second
slice 440 (aka second layer) having a different property such as
color, etc., is wrapped around the core slice 430. As shown in FIG.
11-C, a third slice 450 (aka third layer) of an even different
property such as color, etc.) is wrapped around the second slice
440. As shown in FIG. 11-D, (in this case) three separate outer
pieces 460 are positioned about the periphery of the third slice
450.
[0126] At FIG. 11-E the combined elements are tied together, and
placed in a forming mold with or without the assistance of first
being rolled in a polypropylene sheet (not shown) which is removed
upon insertion into the mold.
[0127] At FIG. 11-G the hair has been shaped, and retied to retain
the shape. At FIG. 11-H, the end opposite the shaped end has been
inserted into a ferrule with or without the assistance of first
being rolled in a polypropylene sheet (not shown) which is removed
upon insertion into the ferrule.
[0128] It should be noted that in the configuration above, the
first 430, second 440, and third 450 slices are of different
properties, such as color, and the outer pieces 460 are of the same
color as the second slice. However, other various substitutions of
properties of the various elements are contemplated under the
inventions.
[0129] Note that the thicknesses and lengths of the slices used for
the Animal Print could be the same or different as the slices used
in the Swirl concept, it just depends on the design desired.
[0130] The Third Manufacturing Process (FIG. 12
[0131] In the third manufacturing process, aka the "Spiral Design"
process, strips of hair are used, but in this case the strips
themselves have patterns/designs built into them (as opposed to
being substantially of one color as in the previous
configurations). The designs shown and/or desired can be provided
by rolling a single strip into a head, rolling two strips together
similar to the first method above, or folding, piecing, and/or
otherwise assembling multiple sections having similar or different
patterns/designs.
[0132] Another possible alternate is that the different colors of
hair could be `premixed` in a sense and then put into a strip,
rolled, cut etc. with another strip of pre-mixed hair to form the
desired effect. The invention anticipates that the multi color
effect would come from both the premix of colors within the strips
and then rolling and cutting multiple strips together. For example,
in the first color option shown in FIG. 12, there may be a
pre-mixing of white and teal together as one `strip` and then roll
it and slice it with a gray as a separate slice.
[0133] Other Variations
[0134] Those skilled in the art will understand that slices of
brush hair can be combined using the concepts of the present
invention in ways other than rolling two slices together. For
example, three or more slices could be rolled together, or slices
could be folded together, or short lengths of slices could be
combined and captured within surrounding slices to form areas of
different types of brush hair within a ferrule. Such areas could be
formed in various shapes. As will be appreciated by one of skill in
the art, various other embodiments of the swirl manufacturing
method described herein may be used to create a swirl brush
head.
CONCLUSION
[0135] Many modifications and other embodiments of the present
invention will come to mind to one skilled in the art to which this
invention pertains having the benefit of the teachings presented in
the foregoing descriptions and the associated drawings. Therefore,
it is to be understood that the invention is not to be limited to
the specific embodiments disclosed and that modifications and other
embodiments are intended to be included within the scope of the
appended claims. Although specific terms are employed herein, they
are used in a generic and descriptive sense only and not for
purposes of limitation.
