FIELD OF INVENTION
[0001] The present invention relates generally to applicators for cosmetics. More particularly,
the present invention relates to ergonomic applicators for applying a cosmetic composition
to eyelashes.
BACKGROUND OF THE INVENTION
[0002] Conventional applicators for applying mascara compositions to eyelashes generally
include a brush held on an elongated rod that is connected to a handle. The bristles
of the brush project radially from the rod. The brush and rod are usually housed in
a cylindrical container. The brush handle forms a closure for the container when the
mascara applicator is not in use.
[0003] When use of the mascara applicator is desired, the handle is pulled away from the
container to remove the mascara-laden brush. During application of mascara to the
eyelashes, the brush rod is generally positioned parallel to the face, and oriented
horizontally with the brush handle held beside a cheek or temple for purposes of manipulation
and alignment of the brush with the eyelashes.
[0004] During transfer of mascara to the eyelashes, the brush is twisted or rotated along
its central axis and moved in a vertical up and down motion, while held in the horizontal
position, such as up to the forehead to do the top eyelashes, and down from the forehead
to do the bottom eyelashes.
[0005] Some users will hold the mascara brush handle in the right hand to apply mascara
to the right eyelashes, and switch the brush handle to the left hand to apply mascara
to the left eyelashes. Other users favor the right or left hand and use the favored
hand to apply mascara to the eyelashes of both the right and left eyes.
[0006] However, even when the favored hand is used for the eyelashes of both eyes, it may
be necessary to hold the mascara applicator in the opposite hand to get to the extreme
ends of the eyelash that are furthest from the favored hand or closest to the nose
bridge.
[0007] It should be noted that the application of mascara with conventional mascara applicators
usually requires dozens of repeated strokes and rotations or twists to achieve the
desired eyelash appearance. Because of the manner in which a conventional mascara
applicator is held and manipulated the application of mascara can be a difficult and
tiresome exercise.
[0008] It is thus desirable to provide a mascara applicator that can be easily manipulated
with a favored or non-favored hand for applying mascara. It is also desirable to provide
a mascara applicator that can be conveniently held with the hand positioned directly
in front of the face rather than off to one side of the head. It is further desirable
to provide a mascara applicator that can be easily manipulated in the same hand to
apply mascara to the full range of eyelash for both eyes.
EP0861616 A1 discloses an applicator with the features summarized in the preamble of claim 1.
SUMMARY OF THE INVENTION
[0009] An ergonomic applicator for applying a cosmetic composition to the eyelashes is provided
comprising (i) a handle portion and (ii) a head portion. The handle portion is suitably
dimensioned to permit the applicator to be held between the thumb and fingers on opposing
faces thereof. The opposing faces are of sufficient width relative to the thickness
separating the faces to prevent rotation of the handle when held between the thumb
and fingers. Preferably, the maximum thickness separating the faces of the handle
portion compared to the maximum width of the handle portion is at a ratio from about
1:5 to about 1:50. The head portion has at its distal end at least one transfer element
comprising a textured surface for holding a charge of cosmetic composition and transferring
it to the eyelashes on contact therewith. The transfer element extends substantially
across the width of the head portion and in a direction orthogonal to a longitudinal
axis of the handle. The longitudinal axis of the head portion is oriented, or is rotatable
to be oriented, at an obtuse angle with respect to the longitudinal axis of said handle.
The obtuse angle is preferably from about 120 degree to about 170 degrees. In a preferred
embodiment, the applicator has a total length from its proximal end to its distal
end from about 35 mm to about 80 mm.
[0010] The head portion has a terminal arcuate edge at the distal end thereof, said arcuate
edge being concave with respect to the head portion. The head portion may also have
an arcuate cross-section about its longitudinal axis. Additionally, the handle portion
may include finger grip enhancements or cut-outs to increase friction between the
handle portion and the thumb or fingers.
[0011] The transfer element may be included on one or both opposing faces of the head portion,
and the transfer element is disposed along the terminal edge at the distal end of
the head portion. The transfer element includes at least one textured surface. The
textured surface includes fins or bristles. More preferably, the bristles have a length
less than 5 mm.
[0012] In certain embodiments, the head portion is rotatably adjustable with respect to
said handle portion so as to adjust the obtuse angle between said longitudinal axis
of said head portion and said longitudinal axis of said handle portion. Preferably,
the head portion and the handle portion are rotatable about an axis orthogonal to
the longitudinal axis of the head portion and the longitudinal axis of the handle
portion. The applicator may further include a hinge permitting rotation of the head
portion with respect to the handle portion.
[0013] A kit including the applicator of the present invention and a container charged with
a liquid cosmetic for application to a keratin fiber is also provided. The container
is configured to receive the head portion of the applicator when inserted into the
container so as to bring said transfer element into contact with the composition.
A wiper is attached to the container for removing excess composition from the transfer
element upon removal of the applicator from the container.
[0014] In addition, the applicator is used in a method for applying mascara to the eyelashes.
The method includes metering a charge of mascara onto the transfer element of the
applicator and transferring the composition to the eyelashes by contacting the transfer
element with the eyelashes while holding the applicator in a substantially vertical
position.
[0015] These and other aspects of the invention will become apparent to those skilled in
the art after a reading of the following detailed description of the invention, including
the figures and appended claims.

DETAILED DESCRIPTION
[0017] The inventive applicator for applying a cosmetic composition generally includes angles
and/or curvatures that provides an ergonomic shape to improve a user's comfort in
applying the cosmetic composition. Specifically, the applicator according to the invention
is particularly useful for application of a cosmetic composition, such as mascara,
to the eye. The applicator according to the invention may also be useful for application
of a variety of cosmetic and personal care products to keratin fibers or to the skin,
including without limitation, eyeliner, hair dye, lipliner, lipstick, lipcolor, lip
gloss, etc. As used herein, the term "keratin fibers" may include, without limitation,
eyelashes, eyebrows, or hair of any part of the body, including the scalp. It is believed
that the applicator of the present invention has an advantageous shape that allows
the applicator to be more conveniently held in the hand of a user and more easily
manipulated by a single hand to apply the cosmetic composition in an efficient and
even manner as compared to conventional cosmetic applicators. In addition, it is believed
that the applicator of the present invention is capable of providing increased coverage
of eyelashes with each stroke and more uniform distribution of mascara compositions
across the length of the eyelashes as compared to conventional cosmetic applicators.
Without being bound by any theory, it is believed that increased coverage of eyelashes
with each stroke is achieved by the advantageous size and shape which provides for
increased contact area with the eyelashes. Accordingly, it is believed that the applicator
can effectively deposit mascara to the eyelashes using fewer strokes than with a conventional
applicator.
[0018] A general embodiment of the applicator
10 according to the invention is shown in Figure 1. The applicator
10 for applying a cosmetic composition, such as a mascara composition, to the eyelashes
includes a handle portion
16 at the proximal end
80 and a head portion
14 at a distal end
70. The handle portion
10 may be operably linked to the head portion
14 in any suitable manner. In one embodiment, the head portion
14 and the handle portion
16 may be integral and formed together in one piece. Alternatively, the head portion
14 and the handle portion
16 may be formed as separate structures and joined together using any suitable technique
in the art. For example, the head portion
14 and the handle portion
16 may be joined by a hinge, by a friction-fit mechanism, by a locking mechanism, by
an adhesive, or by fusing a distal end of the handle portion
16 with a proximate end of the head portion
14. In one embodiment, the head portion
14 may be detachably attached to the handle portion
16. In particular, the handle portion
16 may be detachable from and interchangeably attachable to a plurality of head portions
14.
[0019] The handle portion
16 and the head portion
14 may be connected in any suitable orientation. In one embodiment, the handle portion
16 may be co-linear with the head portion
14 of the applicator
10. Preferably, the handle portion
16 is connected to or integral with the head portion
10 at an angle forming a bended shape, having a generally convex shape on one side where
the head portion
14 is linked to the handle portion
16 and a generally concave shape on an opposing side. The bended shape may be a slight
or an exaggerated deviation from a co-linear formation, forming an offset between
the head portion
10 and the handle portion
16. It is believed that this offset provides a more ergonomic shape to the applicator
10 and can facilitate application of mascara to the eyelashes in a more efficient and
uniform manner as compared to conventional mascara applicators. In certain embodiments,
the applicator
10 may be the widest at the distal end
70 and taper to the narrowest point on the applicator
10 at the bend where the head portion
14 is linked to the handle portion
16. It is also believed that the ergonomic shape of the applicator
10 can improve comfort, allow the applicator
10 to be more conveniently held in the hand of a user, and provide better ability for
manipulating the applicator
10 with a single hand.
[0020] The applicator
10 of the present invention may be in any suitable size and shape. Preferably, the size
and shape of the applicator
10 make it convenient and comfortable for use with either hand, regardless of whether
a user has a favored hand for applying mascara to the eyelashes. In situations where
a user holds the applicator
10 only with the favored hand for application of mascara to the eyelashes on both the
left and right eyes, the applicator
10 is capable of easily accessing the full range of eyelashes for both eyes, including
those eyelashes that are furthest from the favored hand or closest to the nose bridge.
[0021] Preferably, the applicator
10 may be in a relatively small and convenient size for portable use by a consumer.
More preferably, the applicator
10 may be in a size that allows the applicator
10 to be held firmly between the thumb and fingers and prevents radial movements of
the applicator
10 during use and manipulation by a consumer. For example, the total length
(L) of the applicator
10 at the longest point from the proximal end
80 to the distal end
70 may range from about 15 mm to about 80 mm, from about 25 mm to about 80 mm, from
about 25 mm to about 75 mm, from about 35 mm to about 80 mm, from about 35 mm to about
65 mm, or from about 40 mm to about 60 mm. In a specific embodiment, the total length
(L) of the applicator
10 at the longest point may be approximately two inches (or about 50.8 mm), with the
handle portion
16 being slightly more than one inch (about 25.4 mm) in length and the head portion
14 being slightly less than one inch (about 25.4 mm) in length. As used herein, the
total length of the applicator
10 is determined by measuring the length of a third side of a triangle defined on two
sides by the head portion
14 and the handle portion
16. In certain embodiments where the head portion
14 and the handle portion
16 are co-linear and do not overlap in length, the total length
(L) is the sum of the length of the head portion
14 and the length of the handle portion
16. Other suitable dimensions for a relatively small and convenient size include a width
of the distal end
70 of the head portion
14 ranging from about 10 mm to about 50 mm, from about 12.5 mm to about 45 mm, from
about 15 mm to about 40 mm, from about 17.5 mm to about 35 mm, or from about ¾ inch
(about 19.1 mm) to about 1 ¼ inch (about 31.8 mm) and a width of the applicator
10 at its narrowest point ranging from about 5 mm to about 30 mm, from about 7.5 to
about 20 mm, from about 8 mm to about 15 mm, or from about five sixteenths of an inch
(about 7.9 mm) to about three eighths of an inch (about 9.5 mm).
[0022] It is contemplated by the present invention that the head portion
14 and handle portion
16 of the applicator
10 may include other shapes and sizes that are ergonomically comfortable to hold and
manipulate.
[0023] In a preferred embodiment, the longitudinal axis
I-I of the handle portion
16 is positioned or capable of being positioned at an obtuse angle θ with respect to
the longitudinal axis
II-II of the head portion
10. By obtuse angle, it is meant that the angle is greater than 90 degrees but less than
180 degrees. The handle portion
16 and the head portion
10 of the applicator
10 may be fixed at, rotatably adjustable to, or capable of being deformed along an axis
orthogonal to the longitudinal axis
I-I of the handle portion
16 and the longitudinal axis
II-II of the head portion
14 to form the angle θ. In one embodiment, the handle portion
16 may be connected to the head portion
14 via an adjustable hinge (not shown). Specifically, the range of motion of the adjustable
hinge may be limited to form only obtuse angles. In another embodiment, the applicator
10 may be formed from a deformable material to allow a user to bend and deform the applicator
10 to a suitable angle 0. Preferably, the angle θ between the longitudinal axis
I-I of the handle portion
16 and the longitudinal axis
II-II of the head portion
14 range from about 95 to about 175 degrees, more preferably from about 115 to about
170 degrees, even more preferred from about 120 to about 170 degrees, still more preferred
from about 130 to about 165 degrees, and most preferably from about 140 to about 160
degrees.
[0024] The handle portion
14 of the applicator
10 may have any suitable dimensions that permit the applicator to be held between the
thumb and fingers and prevent rotation of the handle when held between the thumb and
fingers. Preferably, the handle portion
16 is narrower than the head portion
14. In one embodiment, as shown in the exemplary embodiments of the present invention
illustrated in Figures 2 through 16, the handle portion
14 includes two opposing faces
86,
88 having sufficient width relative to the thickness separating the faces to prevent
rotation of the handle portion
14 when held between the thumb and fingers. The thickness separating the two faces may
be uniform throughout or may be variable. Particularly, the ratio of the dimension
of the maximum thickness separating the faces to the width of the widest point of
the handle portion
14 may range from about 1:2 to about 1:50, from about 1:5 to about 1:50, from about
1:3 to about 1:25, or from about 1:4 to about 1:20, from about 1:5 to about 1:10.
In certain embodiments, the maximum thickness separating the faces may range from
about 1 mm to about 10 mm, from about 1.25 mm to about 5 mm, from about 1.5 mm to
about 3 mm. In certain embodiments, the handle portion
14 may be substantially within a linear or curved plane. In another embodiment, the
handle portion
14 may be flat.
[0025] The handle portion
14 may also include any suitable modifications that improve the comfort and/or stability
of the applicator
10 when held between the thumb and fingers. One suitable modification includes a convex
contour on at least one of the opposing faces
86 and
88 of the handle portion
14. Another suitable modification may be a convex contour on face
88 of the handle portion
14, which is adapted to be held by a thumb, and a concave contour on the opposing face
86 of the handle portion
14, which is adapted to be held by the fingers. Alternatively, another suitable modification
to the handle portion
14 is shown in the exemplary embodiments shown in Figures 2 through 12. The modification
may include finger grip enhancements
94 that are attached to or formed integrally with the handle portion
14. The finger grip enhancements
94 may include any means for increasing the friction of the handle portion
14 against the thumb and/or fingers, such as but are not limited to, raised semi-circles,
ridges, depressions, other shaped projections or void spaces between such projection.
The finger grip enhancements
94 may be formed unitarily with the handle portion
14 or may be attached by any suitable means, including an adhesive or fusion of the
enhancements
94 with the handle portion
14. The finger grip enhancements
94 may be formed using any suitable technique, including molding and finishing techniques
such as soft touch finish or co-extrusion of polymers.
[0026] Another suitable modification is shown in another exemplary embodiment of the present
invention shown in Figures 13, 15 and 16. The handle portion
14 may be modified to include cut-outs or openings
58 that increase friction between the handle portion
14 and the thumb and/or fingers, thereby facilitate gripping of the handle
16. The cut-outs or openings
58 may be in any suitable shape. Preferably, the cut-outs or openings
58 are narrow or elongated. In the specific embodiments shown in Figures 13, 15 and
16, the cut-outs or openings
58 have an oval shape. In addition, as shown in Figures 13, 15 and 16, the cut-outs
or openings
58 may be arranged parallel to each other. More preferably, the cut-outs or openings
58 having a length perpendicular to the longitudinal axis
I-I of the handle portion
14.
[0027] The head portion
16 is the part of the applicator
10 in contact with at least one transfer element
56 for applying the cosmetic composition. Preferably, the head portion
14 is narrower at its proximal end, where it is linked to the handle portion
16, than at the distal end
70. The head portion
16 provides structural support for the transfer element
56. Additionally, the surface(s) of the head portion
16 may be textured to form a transfer element
56. Preferably, the transfer element
56 extends substantially across the width of the head portion
14 and in a direction orthogonal to the longitudinal axis
I-I of the handle portion
16. By substantially across the width, it is meant that the transfer element
56 extends more than 70%, preferably more than 80%, more preferably more than 90% and
most preferably more than 95% of the width of the head portion
14. The transfer element
56 may also extend across the entire width of the head portion
14. In addition, the transfer element
56 may have any suitable shape. Specifically, the transfer element
56 may have an arcuate exterior shape that substantially conforms or conforms to at
least a quarter, at least a third, at last half or all of the contours formed by the
eyelashes or the eyelid. In certain embodiments, the arcuate exterior shape is convex
while in other embodiments, the arcuate exterior shape may be concave. In some embodiments,
the head portion
16 and the transfer element
56 may be unitary such as in the case where the transfer element
56 constitutes textured surfaces integral with the head portion
16. For example, the head portion
16 and the transfer element
56 may be molded as a solitary piece by injection-molding.
[0028] In a preferred embodiment, such as those exemplary embodiments shown in Figures 2
through 14, the head portion 16 has two opposing faces
40, 42 with a thickness in between. The thickness between opposing faces
40 and
42 may be uniform throughout or may be variable. In one preferred embodiment, the thickness
of the head portion
16 is at a maximum along its longitudinal axis
II-II and decreases as the distance from the longitudinal axis
II-II increases. The transfer element
56 extends from one or both of the opposing faces
40, 42. The transfer element
56 also extends from the distal end
70 of the head portion
14 of the applicator
10. The maximum thickness of the head portion
16 may be less than the width of the widest point of the head portion
16. In particular, the maximum thickness separating the opposing faces
40, 42 as compared to the width of the widest point of the head portion
16 may have a ratio from about 1:2 to about 1:50, from about 1:5 to about 1:25, or from
about 1:10 to about 1:20. In specific embodiments, the maximum thickness separating
the opposing faces of the head portion
16 may range from about 1 mm to about 10 mm, from about 1 mm to about 10 mm, from about
1.25 mm to about 5 mm, from about 1.5 mm to about 3 mm.
[0029] The head portion
16 may also include an additional axis of rotation perpendicular to the longitudinal
axis
II-II of the head portion
16 (not shown). The head portion
16 may be further adjustable about this additional axis. Specifically, the head portion
16 may be formed from two pieces rotatably attached to each other by an adjustable hinge
along this additional axis. The range of motion of the adjustable hinge may be limited
to form only obtuse angles. Preferably, the adjustable hinge may be limited to movements
between from about 95 to about 175 degrees, more preferably from about 100 to about
170 degrees, even more preferred from about 100 to about 170 degrees, more preferred
still from about 105 to about 165 degrees, and most preferably from about 110 to about
160 degrees.
[0030] Preferably, the head portion
16 may have any suitable shape that substantially conforms to or conforms to at least
a quarter of the contours formed by the eyelashes or the eyelid. In one preferred
embodiment, as shown in Figures 2 through 12 any cross-section about the longitudinal
axis
II-II of the head portion
16 may have an arcuate shape. Preferably, the arcuate shape substantially conforms to
or conforms to at least a quarter, at least a third, at last half or all of the contours
formed by the eyelashes or the eyelid. The arcuate cross-section of the head portion
16 about the longitudinal axis
II-II may be convex along the top face
40 and concave along the bottom face
42. Alternatively, the cross-section of the head portion along the top and bottom faces
40, 42 may be concave/concave, convex/convex, planar/planar or any combinations thereof.
The head portion
16 has a terminal arcuate concave edge, at the distal end
70 as shown in Figures 4 through 6 and 13. The terminal concave edge substantially conforms
to or conforms to at least a quarter, at least a third, at last half or all of the
contours formed by the eyelashes or the eyelid.
[0031] In an alternative embodiment, as shown in the exemplary embodiment not covered by
the present invention shown in Figures 15 and 16, the head portion
16 may include a first support, such as a first side leg
30, on a right side of the longitudinal axis
II-II of the head portion
16 and a second support, such as a second side leg
32, on the left side of the longitudinal axis
II-II. The first and second supports form an opening therebetween for receiving and supporting
a transfer element
56. In the specific embodiment show in Figures 15 and 16, the first and second supports
may be formed from a concave terminal edge at the distal end
70 of the head portion
16. The transfer element
56 may be rotatably or non-rotatably mounted along its length between the first and
second supports. The transfer element
56 may have an elongated shape, such as, but not limited to a cylinder or an elongated
oval shape having a circular cross section.
[0032] The transfer element
56, includes means for holding and releasing a cosmetic composition, such as mascara,
and includes a textured surface for holding a charge of cosmetic composition and transferring
it to a keratin fiber, e.g., eyelashes, or the skin on contact. The textured surfaces
may also be capable of imparting various types of aesthetically pleasing appearances
to the eyelashes, such as a volumized appearance, a separated appearance (i.e., the
eyelashes being individually separated from each other), a curly appearance, etc.
sponges, or flocked surfaces. The textured surfaces may be formed from any suitable
substance. In some embodiments, the textured surfaces are formed from silicone or
other soft touch materials. However, it will be understood where bristles become a
sufficient length to be readily bent such as, for example, in a paint brush, the bristles
will no longer be considered to constitute a textured surface, and in such case should
not be included on the terminal edge of the head portion. However, in some embodiments,
it is contemplated that longer bristles, for example, from about 10 to about 20 mm
are within the scope of the invention provided that they are not on the terminal edge
of the head portion, for example, longer bristles may be suitable included on one
or more of the opposing face of the head portion. Bristles according to the invention
will typically be less than 10 mm in length, less than 7.5 mm in length, less than
5 mm in length, less than 2.5 mm in length. The bristles may be, without limitation
integral with the body of the head or may be synthetic fibers implanted in the head.
In one embodiment, the transfer element
56 is not unitary with the head portion
14 and the bristles less than about 5 mm from the base of the transfer element
56. In certain embodiments, any bristles extending out of a terminal end of the applicator
parallel to a plane containing substantially the head portion
14 will be less than about 5 mm, less than about 4.5 mm, less than about 4 mm, less
than about 3.5 mm, less than about 3 mm, less than about 2 mm, or less than about
1 mm. In other embodiments, the transfer element
56 will be free of bristles extending parallel to the plane containing substantially
the head portion
14. In another embodiment, the terminal edge of said head portion is substantially free
of bristles by which is meant that the number of bristles extending from the terminal
edge in a direction parallel to the longitudinal axis
II-II of the head portion
14 are suitably low such that such bristles cannot materially contribute to the application
of mascara over a substantial number of eyelashes during regular use. In other embodiments,
the terminal edge will be free of bristles.
[0033] The texture surface comprises an array of bristles arranged in any suitable shape
or pattern and need not be symmetrical. Examples of suitable patterns include spaced
and parallel rows, staggered rows and columns, linear rows and columns. An array of
projections arranged in parallel rows in the same direction as the longitudinal axis
II-II of the head portion
14, may impart a separated appearance to the eyelashes. In contrast, an array of projections
arranged in staggered rows and columns, may impart a voluminous appearance to the
eyelashes. The density of the array may vary as shown in the exemplary embodiments
shown in Figures 3 through 5, depending on the characteristics of the cosmetic composition
being applied. Differences in the densities of the array of projections may also impart
different aesthetic looks to the eyelashes.
[0034] The cosmetic applicator
10 of the present invention may be placed in a kit with or used in combination with
a reservoir containing or charged with a cosmetic composition, preferably a liquid
cosmetic composition such as a mascara. The reservoir may include at least one wiper
for eliminating excess mascara from the transfer elements
56. In one embodiment, the applicator
10 may serve as a closure element for the reservoir, without the use of a separate closure
device, such as a cap or a cover. The applicator
10 may be used in combination with the reservoir by first placing the head portion
14 into the reservoir so as to bring the transfer element into contact with the mascara
composition and subsequently withdrawing the head portion
14 from the reservoir to meter a charge of mascara onto the transfer element
56. While the head portion
14 of the applicator
10 is being withdrawn from the reservoir, the wiper removes excess mascara from the
transfer element
56 by a smoothing motion and pushing the excess mascara back into the reservoir.
[0035] To use the applicator
10 for applying a mascara composition to the eyelashes, a user may hold the handle portion
16 of the applicator
10 between the thumb and fingers and place the head portion
14 directly in front of the eyelashes in a substantially vertical position, where the
transfer element
56 would be parallel or substantially parallel to the eyelid. By substantially vertical
it is meant generally parallel to the line of the nose. The applicator
10 is then easily moved upwardly (towards the top of the head) or downwardly (toward
the chin) in a single motion such that the transfer element
56 engages and deposits the mascara composition in a uniform manner.
[0036] The size and shape of the handle portion
16 permits the user to ergonomically and stably hold the applicator
10 between the thumb and forefingers and manipulate the applicator
10 for application of a mascara composition to the eyelashes. In particular, the applicator
10 may be suitably sized such that the hand of the user may lean on the cheek or the
forehead for additional support during application of the mascara composition. The
ability to lean on portions of the face such as the cheek or the forehead provides
increased stability and allows the user to more precisely apply mascara to the eyelashes
and avoid a smudged appearance.
[0037] Figures 2 through 12 illustrates some of the currently preferred embodiments of the
applicator
10 according to the invention. The applicator
10 includes a head portion
14 linked to a handle portion
16 at an obtuse angle, forming a generally convex surface 22 on one side where the head
portion
14 is linked to the handle portion
16 and a generally concave surface 24 on an opposing side. The head portion
14 has a side edge
32 on the right side of the longitudinal axis
II-II of the head portion
14 and an opposite side edge
30 on the left side of the longitudinal axis
II-II. The head portion
14 includes an distal end
70 having a slightly concave contour between the opposite side edges
30 and
32. As shown in the exemplary embodiments of Figures 2 through 12, the head portion
14 is narrower at its proximal end where it is linked to the handle portion
16 as compared to the distal end
70 of the head portion
14.
[0038] The embodiment illustrated in Figure 2 also includes a head portion
14 having a top face
40 and a bottom face
42. The top face
40 can be planar but is preferably convex between the opposite side edges
30 and
32. The bottom face
42 is preferably concave between the opposite side edges
30 and
32. The top and bottom faces
40, 42 can also have a concave/concave, convex/convex, planar/planar relationship or any
combinations thereof.
[0039] The thickness between of the top face
40 and the bottom face
42 of the head portion
14 may be uniform or variable. Preferably, the thickness of the head portion
14 between the top face
40 and the bottom face
42 is at a maximum midway between the opposite side edges
30 and
32 of the head portion
14. The head portion
14 may have a minimum thickness at the opposite side edges
30 and
32.
[0040] The top face
40 of the head portion
14 includes a transfer element
56 that extends substantially from the right side edge
32 to the left side edge

56 also extends a predetermined distance from the distal end
70 towards the proximal end
80. The transfer element
56 includes a textured surface for holding a charge of cosmetic composition and transferring
it to the eyelashes on contact. The textured surface includes an array of bristles
57 arranged in staggered or linear rows and columns or random patterns. The density
of the bristles
57 may vary as shown in Figures 4 through 12, depending on the characteristics of the
cosmetic composition being applied.
[0041] In the specific embodiments shown in Figures 2, 3, 4, 7, 8 and 12, the bottom face
42 of the head portion
14 includes a transfer element
56 that extends substantially from the right side edge
32 to the left side edge
30. The transfer element
56 on the bottom face
42 also extends downwardly a predetermined amount from the distal end
70 toward the proximal end
80. The transfer element
56 on the bottom face
42 also includes a surface for holding a charge of cosmetic composition and transferring
it the eyelashes on contact, which includes the array of the bristles
57 arranged in a manner similar to the arrangement of the stub-like projections or bristles
57 on the top face
40.
[0042] In other embodiments of the invention, either the transfer element 56 on the top
face
40 or the transfer element
56 on the bottom face
42 may be omitted.
