Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims the benefit of priority under
35 U.S.C. .sctn.119(e) from U.S. Ser. No. 62/305,856, filed Mar. 9,
2016, the entire contents of which is hereby incorporated by
reference.
FIELD OF THE INVENTION
[0002] The present disclosure relates generally to systems for
applying cosmetic compositions to keratinous material, in
particular to applicators containing a plurality of holes and
associated cosmetic compositions for application to hair, eyebrows
and/or eyelashes.
BACKGROUND OF THE INVENTION
[0003] Cosmetic compositions for making up keratinous materials
such as eyebrows and/or eyelashes (mascaras) typically are marketed
in a system including a reservoir in which the composition is
stored together with a brush for applying the composition to
eyebrows and/or eyelashes. Application of such mascaras occurs by
placing the brush into the reservoir, coating the brush with
mascara, withdrawing the brush from the reservoir, and applying the
mascara to eyebrows and/or eyelashes. This can be a problematic
process.
[0004] More specifically, traditional mascara applicators typically
include a slender brush having a cap on one end that provides a
handle, which may be threaded upon the neck of a container with the
brush located within the mascara. In operation, the cap on the end
of the brush is unscrewed from the container neck with one hand,
and the brush is removed bearing a supply of mascara on its
bristles. The user may then stroke the mascara-laden bristles upon
the eyelashes, and upon completion of the application replace the
brush back with its bristles housed within the container and its
supply of mascara. Such applicators are not as well-suited for a
single hand operation and application.
[0005] Further, the shape and orientation of brush bristles of the
applicator are normally fixed. Therefore, where the design of the
brush applicator is well-suited for applying mascara to the lashes
of one eye with one hand, they are inherently not as well suited
for applying mascara with the same hand to the other eye. For
instance, an applicator that has a generally cylindrical,
peripheral surface of its brush bristles is better-suited for
applying mascara to the central portion of the lashes than to the
end portions. In contrast, where the applicator has a conical shape
of bristles, with the apex of the conical mass located at the tip
of the brush, the brush is well suited for applying with the right
hand mascara to right eyelashes, while it is ill-suited for
applying mascara to the left eye lashes unless a hand switch is
made.
[0006] Additionally, for the above described mascara applicators,
the user needs to frequently dip the brush in the container supply
to secure more mascara on the bristles before further application.
Such a frequent dip and apply process may lead to an uneven amount
of mascara being transported to the brush bristles, which may
result in an uneven application of the mascara.
[0007] The result of the above limitations of mascaras is that many
consumers forego using mascaras, opting to avoid the often
difficult application process.
[0008] Thus, there remains a need for improved cosmetic
compositions for application to keratinous materials such as
mascaras having improved application properties.
[0009] Accordingly, one aspect of the present invention is a care
and/or makeup and/or treatment system for keratinous material which
includes a cosmetic composition having good cosmetic properties
such as, for example, long-wearing, easy to remove, possesses good
anti-flaking properties and/or possess good anti-smudging
properties, where the system allows easy application of the
composition to keratinous material.
SUMMARY OF THE INVENTION
[0010] The present invention relates to a system for applying a
cosmetic composition to a keratinous material comprising a cosmetic
applicator and a cosmetic composition. The cosmetic applicator
includes a container configured to store the cosmetic composition,
an applicator head having a linear or non-linear orientation such
as a curved, bent or conical shape with a proximal end and a distal
end, and a plurality of holes along or around the circumference of
the applicator head, the distal end connected to the container.
Preferably, the container is deformable and/or the applicator head
is flocked with flocking extending on a portion of the applicator
head, extending over a circumference of the applicator head or
extending completely around the circumference of the applicator
head, and covering or exposing the plurality of holes. Preferably,
the cosmetic composition is a mascara and/or the keratinous
material is hair, eyebrows and/or eyelashes.
[0011] The present invention relates to a system for applying a
cosmetic composition to a keratinous material comprising a cosmetic
applicator and a cosmetic composition. The cosmetic applicator
includes a deformable container configured to store the cosmetic
composition, an applicator head having a linear or non-linear
orientation such as a curved, bent or conical shape with a proximal
end and a distal end, and a plurality of holes along or around the

the deformable container. Preferably, the applicator head is
flocked with flocking extending on a portion of the applicator
head, extending over a circumference of the applicator head or
extending completely around the circumference of the applicator
head, and covering or exposing the plurality of holes. In response
to a deformation force applied to the deformable container, the
deformable container transports the cosmetic composition to the
applicator head and further to the flocked brush (if present) via
the plurality of holes for application to the keratinous material.
Preferably, the cosmetic composition is a mascara and/or the
keratinous material is hair, eyebrows and/or eyelashes.
[0012] The present invention relates to a system for applying a
cosmetic composition to a keratinous material comprising a cosmetic
applicator and a cosmetic composition. The cosmetic applicator
includes a cylindrical container (deformable or non-deformable)
configured to store the cosmetic composition, an applicator head
having a linear or non-linear orientation such as a curved, bent or
conical shape with a proximal end and a distal end, and a plurality
of holes along or around the circumference of the applicator head,
the distal end connected to the cylindrical container. Preferably,
the applicator head is flocked with flocking extending on a portion
of the applicator head, extending over a circumference of the
applicator head or extending completely around the circumference of
the applicator head, and covering or exposing the plurality of
holes. In response to a dispensing force applied to the cylindrical
container, the cylindrical container transports the cosmetic
composition to the applicator head and further to the flocked brush
(if present) via the plurality of holes. Preferably, the cosmetic
composition is a mascara and/or the keratinous material is hair,
eyebrows and/or eyelashes.

DETAILED DESCRIPTION OF THE INVENTION
[0026] In the following description of the invention and the claims
appended hereto, it is to be understood that the terms used have
their ordinary and accustomed meanings in the art, unless otherwise
specified.
[0027] "About" as used herein means within 10% of the indicated
number (e.g. "about 10%" means 9%-11% and "about 2%" means
1.8%-2.2%).
[0028] "A" or "an" as used herein means "at least one."
[0029] As used herein, all ranges provided are meant to include
every specific range within, and combination of subranges between,
the given ranges. Thus, a range from 1-5, includes specifically 1,
2, 3, 4 and 5, as well as subranges such as and 2-5, 3-5, 2-3, 2-4,
1-4, etc.
[0030] "Film former", "film-forming polymer" or "film forming
agent" or "co-film former" as used herein means a polymer or resin
that leaves a film on the substrate to which it is applied, for
example, after a solvent accompanying the film former has
evaporated, absorbed into and/ or dissipated on the substrate.
[0031] "Wax" as used herein is a lipophilic fatty compound that is
solid at ambient temperature (25.degree. C.) and changes from the
solid to the liquid state reversibly, having a melting temperature
of more than 30.degree. C. and, for example, more than 45.degree.
C., which can be as high as 150.degree. C., a hardness of more than
0.5 MPa at ambient temperature, and an anisotropic crystalline
organization in the solid state.
[0032] "Free" or "devoid" of as it is used herein means that while
it is preferred that no amount of the specific component be present
in the composition, it is possible to have very small amounts of it
in the compositions of the invention provided that these amounts do
not materially affect at least one, preferably most, of the
advantageous properties of the compositions of the invention. Thus,
for example, "free of solvents" means that non-aqueous solvents are
preferably omitted (that is 0% by weight), but can be present in
the composition at an amount of less than about 0.25% by weight,
typically less than about 0.1% by weight, typically less than about
0.05% by weight, based on the total weight of the composition.
[0033] "Makeup Result" as used herein, refers to compositions where
color remains the same or substantially the same as at the time of
application, as viewed by the naked eye, after an extended period
of time. "Makeup Result" may be evaluated by evaluating long wear
properties by any method known in the art for evaluating such
properties. For example, long wear may be evaluated by a test
involving the application of a composition to keratin materials
such as eyelashes and evaluating the color of the composition after
an extended period of time. For example, the color of a composition
may be evaluated immediately following application to keratin
materials such as eyelashes and these characteristics may then be
re-evaluated and compared after a certain amount of time. Further,
these characteristics may be evaluated with respect to other
compositions, such as commercially available compositions.
[0034] "Making up" as used herein means to provide decoration (for
example, color) to keratin materials such as the eyelashes.
[0035] "Protecting" as used herein means to inhibit damage to
keratin materials such as the eyelashes by providing a protective
layer on the keratin materials.
[0036] "Substituted" as used herein, means comprising at least one
substituent. Non-limiting examples of substituents for substitution
include atoms, such as oxygen atoms and nitrogen atoms, as well as
functional groups, such as hydroxyl groups, ether groups, alkoxy
groups, acyloxyalkyl groups, oxyalkylene groups, polyoxyalkylene
groups, carboxylic acid groups, amine groups, acylamino groups,
amide groups, halogen containing groups, ester groups, thiol
groups, sulphonate groups, thiosulphate groups, siloxane groups,
and polysiloxane groups. The substituent(s) may be further
substituted.
[0037] "Water resistance" as used herein, means resistance of a
material (substance) to the penetration of water, which may cause
degradation of that material. The method implemented if assessment
of this invention is further disclosed.
[0038] "Transfer resistance" as used herein refers to the quality
exhibited by compositions that are not readily removed by contact
with another material, such as, for example, a glass, an item of
clothing or the skin, for example, when eating or drinking.
Transfer resistance may be evaluated by any method known in the art
for evaluating such. For example, transfer resistance of a
composition may be evaluated by a "kiss" test. The "kiss" test may
involve application of the composition to human keratin material
such as hair, skin or lips followed by rubbing a material, for
example, a sheet of paper, against the hair, skin or lips after
expiration of a certain amount of time following application, such
as 2 minutes after application. Similarly, transfer resistance of a
composition may be evaluated by the amount of product transferred
from a wearer to any other substrate, such as transfer from the
hair, skin or lips of an individual to a collar when putting on
clothing after the expiration of a certain amount of time following
application of the composition to the hair, skin or lips. The
amount of composition transferred to the substrate (e.g., collar,
or paper) may then be evaluated and compared. For example, a
composition may be transfer resistant if a majority of the product
is left on the wearer's hair, skin or lips. Further, the amount
transferred may be compared with that transferred by other
compositions, such as commercially available compositions. In a
preferred embodiment of the present invention, little or no
composition is transferred to the substrate from the hair, skin or
lips.
[0039] The compositions and methods of the present invention can
comprise, consist of, or consist essentially of the essential
elements and limitations of the invention described herein, as well
as any additional or optional ingredients, components, or
limitations described herein or otherwise useful.
[0040] Referred to herein are trade names for materials including,
but not limited to polymers and optional components. The inventors
herein do not intend to be limited by materials described and
referenced by a certain trade name. Equivalent materials (e.g.,
those obtained from a different source under a different name or
catalog (reference) number) to those referenced by trade name may
be substituted and utilized in the methods described and claimed
herein.
[0041] All percentages and ratios are calculated by weight unless
otherwise indicated. All percentages are calculated based on the
total weight of a composition unless otherwise indicated. All
component or composition levels are in reference to the active
level of that component or composition, and are exclusive of
impurities, for example, residual solvents or by-products, which
may be present in commercially available sources.
[0042] Furthermore, where a range of values is provided, it is to
be understood that each intervening value between an upper and
lower limit of the range and any other stated or intervening value
in that stated range is encompassed within the disclosure. Where
the stated range includes upper and lower limits, ranges excluding
either of those limits are also included.
[0043] The following disclosure is to aid the reader in
understanding the present invention, but it is not intended to vary
or otherwise limit the meaning of the invention or terms/phrases
describing the invention.
[0044] System For Applying A Cosmetic Composition To Keratinous
Material
[0045] According to the present invention, a system for applying a
cosmetic composition to a keratinous material comprising a cosmetic
applicator and a cosmetic composition is provided. Preferably, the
cosmetic composition is a mascara and the keratinous material is
hair, eyebrows and/or eyelashes.
[0046] Cosmetic Applicator
[0047] According to the present invention, a cosmetic applicator
comprising a container configured to store the cosmetic
composition, an applicator head having a linear or non-linear
orientation such as a curved, bent or conical shape with a proximal
end and a distal end, and a plurality of holes along or around the
circumference of the applicator head, the distal end connected to
the container is provided. According to preferred embodiments, the
cosmetic applicator further comprises a flocked brush with flocking
extending on a portion of the applicator head, extending over a
circumference of the applicator head or extending completely around
the circumference of the applicator head, and covering or exposing
the plurality of holes.
[0048] According to preferred embodiments, the container is a
deformable container. In accordance with this embodiment of the
present invention, in response to a deformation force applied to
the deformable container, the container transports the cosmetic
composition to the applicator head for application to keratinous
material. According to preferred embodiments, the cosmetic
applicator further comprises a flocked brush with flocking
extending on a portion of the applicator head, extending over a
circumference of the applicator head or extending completely around
the circumference of the applicator head, and covering or exposing
the plurality of holes and the deformation force further transports
the cosmetic composition to the flocked brush via the plurality of
holes for application to the keratinous material.
[0049] According to preferred embodiments, the container is a
cylindrical container having a depressible element such as, for
example, a piston or a plunger. According to this embodiment, the
container may be deformable or non-deformable. In accordance with
this embodiment of the present invention, in response to a
dispensing force applied to the container and/or depressible
element, the container transports the cosmetic composition to the
applicator head for application to keratinous material. According
to preferred embodiments, the cosmetic applicator further comprises
a flocked brush with flocking extending on a portion of the
applicator head, extending over a circumference of the applicator
head or extending completely around the circumference of the
applicator head, and covering or exposing the plurality of holes
and the dispensing force further transports the cosmetic
composition to the flocked brush via the plurality of holes for
application to the keratinous material.
[0050] As indicated above, according to preferred embodiments of
the present invention, the cosmetic applicator comprises a flocked
brush for applying the cosmetic composition (e.g., mascara). A
"flocked brush" is constituted of a material which has been made by
standard flocking techniques. A flocked brush is preferred for
application of a composition to hair, eyebrows and/or eyelashes.
However, if the cosmetic composition is intended for application to
skin or lips (for example, a lip gloss), the cosmetic applicator of
the invention system need not include a flocked brush.
[0051] Exemplary details of the cosmetic applicator of the
invention systems will now be described.
[0052] Referring now to the drawings, like reference numerals
designate identical or corresponding parts throughout the several
views. The drawings are not drawn to scale. Accordingly, the
following discussion discloses and describes merely exemplary
embodiments of the present disclosure. As will be understood by
those of ordinary skill in the art, the present disclosure may be
embodied in other specific forms without departing from the spirit
or essential characteristics thereof. Accordingly, the present
disclosure is intended to be illustrative, but not limiting, of the
scope of the present invention. The disclosure, including any
readily discernible variants of the teachings herein, defines, in
part, the scope of the foregoing claim terminology such that no
inventive subject matter is dedicated to the public.
[0053] FIG. 1 shows an exemplary flocked mascara applicator 100 in
which one or more technologies or methodologies can be implemented,
such as, for example, having an applicator that provides a
mechanism of applying mascara in a seamless manner and/or provides
a pleasant sensation when used. In an embodiment, the flocked
mascara applicator 100 is a two- to three-piece device including an
applicator head 101 having an end portion 101a and a deformable
container 103 (also referred herein as a tube 103). In an
embodiment, the container 103 is provided as a hollow container
that carries the cosmetic composition (e.g., mascara or other fluid
material) and deforms upon application of force. The tube 103 can
be of different shape such as a pipe-shaped, grip shaped, or any
other shape that can be held and deformed with fingers or
palms.
[0054] In one embodiment, the tube 103 is essentially shaped as a
cylinder that is pinched (sealed) at one end (distal end) and
connected to the applicator head 101 at the other end (proximal
end). The tube 103 may be hermetically sealed at the distal end in
order to provide a sealed container. Furthermore, the inside walls
of the tube 103 may be coated with special coatings in order to
inhibit the tube's material from reacting with the contents.
[0055] The tube 103 may be attached at its proximal end to the
applicator head 101 via any suitable means such as, for example, a
locking mechanism such as, for example, a click-lock mechanism
during assembly or it may be twisted together with the applicator
head 101 via a threading mechanism (not shown). In one embodiment,
the tube 103 is a soft-squeezable reservoir that may be made of any
suitable deformable material such as, for example, plastic,
paperboard, aluminum or the like. The volume of the tube can be of
any size, but preferably of a size which contains 1.5 to 20 ml, 1.5
to 17 ml, and preferably 1.5 to 15 ml of cosmetic composition.
However, it must be appreciated that smaller-sized tubes can be
manufactured, for example, for a travel-size applicator.
Furthermore, the applicator 100 can be manufactured as a one-piece
unit where the tube and the applicator head forms a unitary
construction. Such applicators, upon use, can be discarded, if
desired. A refill (with cosmetic composition) provision for the
one-piece applicator can also be provided.
[0056] The applicator head 101 includes a proximal end that is
attached to the tube 101 and a distal end that includes a flocked
brush 105. The applicator head 101 may be made of a soft or hard
material. In one embodiment, the applicator head is curved in
shape, wherein the degree of curvature is such that the mascara
tube 100 provisions for easy application of the mascara to curved
surfaces such as a user's eyebrows and/or eyelashes. The degree of
curvature may be predetermined in a manner that is deemed
appropriate to one of ordinary skill in the art to achieve desired
application to the desired keratinous material. Additionally, in an
embodiment, the flocked brush 105 may be oriented in a manner such
that a longitudinal axis or the flocked brush is substantially
parallel to the longitudinal axis of the tube 103.
[0057] As shown in FIGS. 2A and 2B that depict left and right side
perspective views of the flocked applicator 100, respectively, the
flocked material (brush) 105 is extended over an end portion 101a
of the applicator head 101, and around the circumference. For
example, the flocked brush 105 can be spread partially or fully
along the circumference of the applicator head 101. In one
embodiment, the flocked brush 105 preferably covers one-third to
one-half of the circumference of the applicator head 101. In doing
so, the mascara applicator provisions for the application of the
mascara at the corners and bottom of eyelashes in an easy manner.
The extension of the flocked brush 105 over the end portion 101a of
the applicator head 101 is further shown in FIGS. 2C and 2D which
depict the front side and back side prospective views of the
mascara tube of FIG. 1. Moreover, FIGS. 2E and 2F depict exemplary
top and bottom views of the mascara tube of FIG. 1,
respectively.
[0058] Referring to FIG. 2A and 2B, the applicator head 101 has a
curvature defined by an angle .theta..sub.1. Due to the curvature,
the flocked brush 105 is inclined with respect to a longitudinal
axis of the applicator 100. Increasing or decreasing the angle
.theta..sub.1 can affect the amount of mascara transported to the
flocked brush 105. For example, an acute angle .theta..sub.1 (e.g.,
less than 90.degree.) may need higher force on the tube 103
compared to an obtuse angle .theta..sub.1 (e.g., greater than
100.degree.) to transport a particular amount of mascara to the
flocked brush 105. Providing an optimum curvature should be
maintained to allow easy transportation and application of cosmetic
composition such as mascara. Preferably, the angle .theta..sub.1 is
between about 90 and about 260, preferably between about 110 and
about 200, and preferably about 120 and about 180. The angle
.theta..sub.1 may also interact with properties of the cosmetic
composition such as, for example, viscosity, consistency, and
critical strain. For example, for a lower viscosity and/or lower
consistency mascara, a smaller angle may provide sufficient
resistance to transport an optimum amount of mascara to the flocked
brush 105 than a higher viscosity and/or consistency.
[0059] The flocked mascara applicator 100 provisions for easy
transport of the mascara from the tube to the flocked brush 105 and
utilizes the curvature of the applicator head 101 for easy
application of the mascara. Furthermore, it may be possible to
provide for refills of the tube and/or switching the applicator
head.
[0060] Referring to FIG. 2C and 2D, the applicator head 101 can be
of length L3, and the flocked brush 105 can have a length L1 on the
front side and a length L2 on the back side of the applicator head
101. The length of the flocked brush 105 can also affect an optimum
amount of mascara discharged on the flocked brush 105. For example,
if the length L1 of the flocked brush 105 is long, more mascara may
be discharged to realize a uniform wetting of the flocked brush
105.
[0061] Referring back to FIGS. 2A and 2B, the applicator head 101
has an interior applicator channel 110 conforming to the shape of
the applicator head 101. The interior applicator channel 101 can
extend from an opening of the tube 103 to the end portion 101a of
the applicator head 101. The interior applicator channel 110
receives mascara from the tube 103 via hole(s) (refer to FIG. 8)
and transports the mascara to the flocked brush 105. The interior
applicator channel 101 can have a diameter preferably ranging from
0.5 mm to 5 mm, preferably 0.75 mm to 4.5 mm, and preferably from 1
mm to 3 mm. The channel 101 can have a uniform diameter or can have
a varying diameter of any type, for example a diameter decreasing
or increasing towards the end portion 101a of the applicator head
101 resulting in a tapered shape. Such tapering is particularly
preferred in embodiments in which the applicator head has a conical
shape. The size of the hole is such that there is little or no
leakage of mascara between the tube hole(s) and the interior
applicator channel 110.
[0062] The flocked brush 105 can be made of any suitable material
used for flocking materials such as, for example, polyamides,
polyesters, rayons, cottons, celluloses, polyacryles, carbone
fibers, aramids, etc. Suitable materials include those made and
sold under the Hytrel.RTM. name. Preferably, the flocked brush 105
is made of materials having (1) 1.5 to 90 dtex, preferably 10 to 80
dtex, and preferably 15-70 dtex, including all ranges and subranges
therebetween, (2) 0.5 to 3 mm in length, preferably 0.6 to 2.9 mm
in length, and preferably 0.7 to 2.5 mm in length, including all
ranges and subranges therebetween, and/or (3) 0.03 to 0.09 mm in
diameter. The flocked brush 105 may optionally include polymeric
micro-bristles that may be adhered to the applicator head 101 by
injection molding techniques, electrostatic techniques and the
like. In use, the flocked applicator 100 can transport the mascara
from the tube 103 to the flocked brush 105 upon squeezing of the
tube 103 (deformable container) or by employing a depressible
elements such as a movable piston mechanism within the tube 103 to
push the mascara onto the flocked brush 105. The cosmetic
composition deposited on the flocked brush 105 may then be applied
to the hair, eyebrows and/or eyelashes of the user.
[0063] Referring to FIG. 3, an example of a flocked mascara
applicator 300 which is a three-piece device including an
applicator head 301 having an end portion 301a and a pen 303 that
has a pen-shaped structure is depicted. The body of the pen 303 is
a hollow cylindrical container (deformable or non-deformable) that
carries the cosmetic material (mascara). In one embodiment, the pen
is air-sealed at one end (distal end) and connected to the
applicator head 301 at the other end (proximal end). Additionally,
the inside walls of the pen may be coated with special coatings in
order to prevent the tube's material from reacting with the
contents.
[0064] The pen 303 may be attached at its proximal end to the
applicator head 301 via any suitable means such as, for example, a
locking mechanism such as, for example, a click-lock mechanism
during assembly or it may be twisted together with the applicator
head 301 via a threading mechanism. The pen 303 may be made of
plastic, aluminum or the like. The volume of the pen can be of any
size, but preferably of a size which contains 0.75 to 5 ml, 1 to
4.5 ml and preferably 1.5 to 4 ml of cosmetic composition. However,
it must be appreciated that smaller sized pens can be manufactured,
for example, a travel-size flocked applicator. Furthermore, the
applicator 300 can be manufactured as a one-piece unit where the
pen and the applicator head form a unitary construction. Such
applicators, upon use, can be discarded, if desired. A refill (with
cosmetic composition) provision for such a one-piece applicator may
further optionally be provided.
[0065] The applicator head 301 includes a proximal end that is
attached to the tube 101 and a distal end that includes a flocked
brush 305. The applicator head 301 may be made of a soft or hard
polymer-like material. In one embodiment, the applicator head is
curved in shape, wherein the degree of curvature is such that the
mascara applicator 300 provisions for easy application of the
mascara to curved surfaces such as a user's eyelashes as discussed
above.
[0066] The flocked brush 305 is preferably made of the materials
discussed above. The flocked brush 305 may optionally include
polymeric micro-bristles that may be adhered to the applicator head
301 by injection molding techniques, electrostatic techniques and
the like. In use, the flocked applicator 300 can transport the
mascara from the body of the pen 303 to the flocked brush 305 by
using a dispensing mechanism based on clicking or using a push pen
with a movable piston-like mechanism. It should be appreciated that
any structure that moves the mascara from the pen to applicator 301
can be used. Additionally, the pen 303 may transfer the cosmetic
composition to the brush 305 by shaking the pen 303 in a back and
forth manner. The cosmetic composition deposited on the flocked
brush 105 may then be applied to the hair, eyebrows and/or
eyelashes of the user.
[0067] As shown in FIGS. 4A and 4B that depict left and right side
perspective views of the flocked applicator 300, respectively, the
flocked material (brush) 305 is extended over the end portion 301a
of the applicator head 301 or around the circumference. For
example, the flocked brush 305 can be spread partially or fully
along the circumference of the applicator head 301. In one
embodiment, the flocked brush 305 can cover one-third to one-half
of the circumference of the applicator head 301. Such spread of the
flocked brush 305 enables easy application of the mascara at the
corners and bottom of eyelashes easier. This is further evident in
FIGS. 4C and 4D that depict exemplary front side and back side
prospective views of the mascara pen of FIG. 3. Accordingly, the
flocked mascara applicator 300 provisions for easy transport of the
mascara from the pen 303 to the flocked brush and utilizes the
curvature of the applicator head for easy application of the
mascara. Moreover, FIGS. 4E and 4F depict exemplary top and bottom
views of the mascara pen of FIG. 3 respectively. Furthermore, since
the flocked applicator is a three-piece device, a provision of
purchasing refills of the tube and/or switching the applicator head
can be further provided.
[0068] Referring to FIG. 4A and 4B, in one embodiment the
applicator head 301 can have a curvature defined by an angle
.theta..sub.2. The angle .theta..sub.2 can be different from the
angle .theta..sub.1, as the dispensing mechanism for the applicator
300 having the pen 303 can be different, for example, squeezing for
tube 103 and shaking or pushing by a movable piston for the pen
303. The curvature of the applicator head 301 (or 101) can be a
function of the type of reservoir (e.g., tube 103 or pen 303) and
dispensing mechanism. Providing an optimum curvature should be
maintained to allow easy transportation and application of mascara.
Preferably, the angle .theta..sub.2 is between about 90 and about
260, preferably between about 110 and 200, and preferably between
about 120 and 180. The angle .theta..sub.2 may also interact with
properties of the cosmetic composition such as, for example,
viscosity, consistency, and critical strain. For example, for a
lower viscosity and/or lower consistency mascara, a smaller angle
may provide sufficient resistance to transport an optimum amount of
mascara to the flocked brush 305 than a higher viscosity and/or
consistency.
[0069] Referring to FIG. 4C and 4D, the applicator head 301 can be
of length L6, and the flocked brush 305 can have a length L4 on the
front side and a length L5 on the back side of the applicator head
301. The length of the flocked brush 305 can affect an optimum
amount of mascara discharged on the flocked brush 305. For example,
if the length L4 of the flocked brush 305 is long, more mascara
should be discharged to wet the flocked brush 305.
[0070] It must be appreciated that the shape of the cosmetic
applicators 100 and 300 as shown in FIG. 1 and FIG. 3,
respectively, can provide for ease of application and positioning
of the flocked brush directly in contact with hair, eyelashes
and/or eyebrows. For instance, referring to FIG. 1, crimping along
the axis of the tube 103, provisions for easier grip of the tube.
Such an orientation of the cosmetic applicator positions the
flocked brush directly towards the eyelashes, thereby enhancing the
ease of cosmetic application, without the need to twist and/or roll
the applicator for applying the mascara.
[0071] Referring to FIGS. 5A and 5B, exemplary dual function caps
are illustrated. As shown in FIG. 5A, the dual function cap
includes a cap 501 and a seal 503 that are enclosed in a casing
(container) 502. The cap 501 along with the seal 503 prevents the
mascara from drying on the applicator head. In one embodiment, the
cap 501 may be a mold that has the shape of the applicator head,
and can be fitted snugly to cover the applicator head. For
instance, the applicator head may be snapped onto the cap or
attached via threading and a twist mechanism. The cap 501 can also
hold excess bulk composition preventing the applicator from drying
out. The cap 501 can also serve the role of holding product
vertically in place and can have any shape which allows it to do
so. The seal 503 can be made of a hard or soft pliable material and
is used to further prevent drying of the mascara. The cap and seal
combination may be included in the casing to provide an air tight
mechanism in which the applicator head can be maintained.
Additionally, the cap can include a holding mechanism such as a
snap-on clip, carabiner clip, or the like, which enables a user of
the cosmetic applicator to affix the applicator to a bag, pockets
of a trouser, and the like, thereby making the cosmetic applicator
portable.
[0072] The applicator head 101 (or 301) discharges the cosmetic
composition such as mascara on to the flocked brush 105 (or 305)
via a plurality of holes. According to preferred embodiments of the
present invention, the number of holes in the plurality of holes
preferably ranges from 2 to 10, preferably from 3 to 9, and
preferably from 4 to 8. The plurality of holes can be in any
orientation or pattern such as, for example, tabular (e.g., rows
and columns of holes), circular, square, triangular, or other
appropriate geometrical forms. Preferably, the plurality of holes
is in an in-line orientation or a zig-zag orientation. Also, the
holes themselves can be of any geometry such as, for example,
circular, square, amorphous, rectangular, oval, etc. Preferably,
the holes are of all the same geometry, and preferably the holes
are all circular. The plurality of holes can be positioned anywhere
along the length of the applicator head 101 (or 301) covered with
the flocked brush 105 (or 305). Preferably, the plurality of holes
are in an orientation having a length which is at least about 40%
of the length of the applicator head, preferably at least about 50%
of the length of the applicator head, and preferably at least about
60% of the length of the applicator head.
[0073] Preferably, when circular, the holes have a diameter smaller
than 2 mm, preferably smaller than 1.7 mm, preferably smaller than
1.5 mm while preferably being larger than 0.3 mm, preferably larger
than 0.5 mm, preferably larger than 0.6 mm and preferably larger
than 0.7 mm, including all ranges and subranges therebetween such
as, for example, 0.6 mm to 2.0 mm, 0.65 mm to 1.7 mm, and 0.68mm to
1.6 mm. Of course, if the holes are of different geometry, the size
of the holes would correspond to the size of the circular holes
identified above (for example, area of non-circular holes would
correspond to the area per the formula area=nr.sup.2 for the
diameters identified above).
[0074] The plurality of holes controls an amount of mascara
discharge on the flocked brush 105 (or 305). FIG. 8 illustrates a
location of the plurality of holes with respect to the applicator
head 101. The plurality of holes (e.g., H1, H2, H3, H4) is located
on applicator head 301 (or 101) under the flocked brush 305 (or
105). The mascara discharged from the plurality of holes is
received by the flocked brush 305 (or 105).
[0075] The amount of cosmetic composition such as mascara
discharged can be a function of, among other things, a diameter of
the plurality of holes, an orientation of the plurality of holes,
the number of holes, cosmetic composition (mascara) properties
including viscosity, consistency, critical strain, force applied to
the tube 103 (or 303), and flock material. An optimum amount of
mascara should be discharged to provide deposit of product on the
flocked brush 105 (or 305), so that the mascara or cosmetic
composition can be applied to a surface such as user's hair,
eyelashes or eyebrows.
[0076] FIG. 7A illustrates, in a non-limiting manner, three
variations of an applicator S100 that includes applicators with
either a head S101, a head S103, or a head S104. The heads S101,
S103, and S104 are unflocked for illustration purposes. The heads
S101, S103, and S104 each have four holes oriented in-line.
Further, each of the four holes of the head S101 (or S103 or S104)
can have different diameters. Exemplary dimension of holes of the

[0077] FIG. 7B illustrates two variations of applicator S200 that
includes applicators with either a head S201, or a head S204. The
heads S201 and S204 are unflocked for illustration purposes. The
heads S201 and S204 each have seven holes oriented in-line.
Further, each of the four holes of the head 3101 (or S103 or S104)
can have different diameters. Exemplary dimension of holes of each
head S201, and S204 are illustrated in table of FIG. 6.
[0078] FIG. 70 illustrates three variations of S300 that includes
applicators with either a head S301, a head S303, and third head
S304. The heads S301, S303, and S304 are unflocked for illustration
purposes. The heads S301, S303, and S304 each have seven holes
oriented in a zig-zag manner. Further, each of the four holes of
the head S101 (or S103 or 3104) can have different diameters.
Exemplary dimension of holes of each head S301, S303, and S304 are
illustrated in table of FIG. 6.
[0079] FIG. 7D illustrates applicator S700 that includes a head
S703. The head S703 is unflocked for illustration purposes. The
head S703 has four holes oriented in-line. Further, each of the
four holes of the head S101 (or S103 or S104) can have different
diameters. Exemplary dimension of holes of head S703 is illustrated
in table of FIG. 6.

Testing of Composition Properties
[0124] Compositions in Example 1 were tested for viscosity, complex
modulus (G*) and critical strain (yc) properties. The extrusion
force associated with applying compositions in example 1 via
applicators of the present invention was also determined. Results

Example 2A
Testing Protocols
[0125] Viscosity. Method A. The viscosity of the formulas were
measured at 25.degree. C. with a Brookfield DVIIT viscometer in the
absence of the guard leg, using the spindle and rpm listed in Table
4 (hereinafter, "Method A"). The reported viscosity is that shown
is that after 10 minutes after switching on the rotation of the
spindle (when a constant torque is read) and the values are
reported in cps.
[0126] Consistency and critical strain. Method B. Complex modulus
(G*) and critical strain (.gamma.c) of inventive compositions
determined from a strain sweep experiment at 20.degree. C. using a
TA instrument AR-G2 or AR-DH2 rheometer and a 40 mm stainless steel
2.degree. cone or crosshatch probe from 0.01 to 1000% strain at 1
rad/sec angular frequency.
[0127] Extrusion Force. Tubes were filled with 15 grams of bulk and
sealed. Tubes placed on balance on their side and balance was
tarred. Tube pressed with hand and the amount of force required to
dispense the product was recorded. The result of dispensing was
also recorded. The result of dispense was recorded as tubes, uneven
mountain, tubes that wet evenly along the applicator, even
applicator wetting.

Testing of Cosmetic Systems of the Present Invention
Example 3A
Basic Applicators for Evaluating Cosmetic Compositions
[0130] Applicators as depicted in FIGS. 7A, 7B and 7D were used in
conjunction with compositions from Example 1B. The formulations
evaluated included W/O formulation (Example 1B6), wax-free mascara
O/W formulations (Examples 1B1-3) and anhydrous lip gloss
compositions (Examples 1B4-5). Commercial products were also
tested.
[0131] FIG. 6 identifies the plurality of holes used for each
system tested as well as the orientation of the plurality of holes
(in-line or zig-zag).
Example 3B
Evaluation of Dispensing Force for Composition 1B1 in Applicators
With Varying Hole Numbers and Sizes
[0132] Dispensing force associated with Composition 1B1 was
evaluated in dispensers containing 4 or 7 holes of varying sizes
(diameters). The results determined according to Method C above are
set forth below.
[0133] The data above demonstrates that a formula with a viscosity
of 41200 cps (RV-6, 10 rpm) dispensed most uniformly across the
applicator with 4 holes in series if the holes are greater 1 mm,
but less than 1.5 mm. The larger holes allowed for too much product
to dispense. Holes of a diameter less than 1 mm resulted in
worm-like tubes an undesired result. The optimal applicator for
wetting was observed with 7 holes either in-line or in zig-zag
formation. The diameter of the hole ranging from 0.7-1.4 mm proved
optimal with all showing uniform applicator wetting. Unexpectedly,
dispensing force reduced with smaller size holes with an ideal
range for dispensing force between 700-1000 grams for this
particular example.
Example 3C
Evaluation of Dispensing Force for Composition 1B3 in Applicators
With Varying Hole Numbers and Sizes
[0134]
[0135] For Example 1B3 which was more fluid than Example 161, a
lower force (600-700 g) was required overall to dispense product.
Most applicators dispensed the more fluid product 1B3 evenly with
only applicator 303 and 703 releasing slightly more product in the
first hole, which had either 7 holes (1.1-1.4 mm) or 4 holes
(1.5-1.8 mm). In contrast to what was expected, the larger the hole
size, the more force was required to dispense. Although higher
forces were required to dispense the product, most holes displayed
even wetting across the applicators for this particular
example.
Example 3D
Evaluation of Dispensing Force for Commercial Product A in
Applicators With Varying Hole Numbers and Sizes
[0136]
[0137] For Commercial Product A (a traditional mascara containing
waxes, but has lower consistency (G*<10000 but >5000 Pa), the
product was dispensed in small tubes (an undesired result) with
applicators with 1 mm holes. But, more promising results with
Commercial Product A were seen for holes >1 mm but less than 1.5
mm.
Example 3E
Evaluation of Dispensing Force for Unflocked Applicators
[0138] The following unflocked applicators having 4 holes in-line
were evaluated.
TABLE-US-00006 Hole 1 Hole 2 Hole 3 Hole 4 ID (mm) (mm) (mm) (mm)
Comments 1 (0.7 to 1.0 mm) 4 holes 2 (0.9 to 1.2 mm) 4 holes 3 (1.1
to 1.4 mm) 4 holes 4 (0.8 mm) 4 holes 5 (1.0 mm) 4 holes 6 (1.1 mm)
4 holes
[0139] These unflocked applicators having 4 holes in-line were
evaluated in combination with fluid formulations from example 1 as
follows.
[0140] For fluid W/O formulation Example 1B6, the formula bled out
of the applicator without force. More viscous formulations Example
1B1 and 1B2 are viscous enough to not bleed out. For Example 1B2,
forces greater than 1100 grams were required to dispense the
product through all holes with product dispensed in undesired
worm-like tubes. Example 1B1 did not leak and required lower
extrusion force, with the optimal results achieved with applicator
1.
[0141] For Commercial Product A (a traditional mascara with waxes)
the product dispensed in small tubes an undesired result. The most
promising result was for holes with diameter >1.4-1.2 mm.
Summary of Evaluations
[0142] The invention systems employ fluid compositions which are
compatible with a flow-through tube with applicator. The cosmetic
compositions preferably have optimal (a) viscosity (b) consistency
(G*) and (c) critical strain (yc) to be dispensed through and
applicator with (a) series of 4-7 holes in in-line or zig-zag
orientation. The optimal force (force that is perceived as easy) to
dispense the product ranges from 100-1400 grams.
[0143] The best results obtained were with cosmetic compositions
that had a consistency (G*) of less than 11000 Pa and a critical
strain less than 6%. These compositions are identified in the Table
above along with their consistency (G*) and critical strain
values
