Claims
I claim:
1. An applicator for applying a false eyelash to a human eyelid in
a manner such that vision of the user in both eyes is substantially
unobstructed to permit the user to have stereoscopic vision and
good depth perception during the application of the eyelash, said
applicator comprising a pair of elongated straight flexible
resilient coextensive members, means joining said members at one
common pair of ends thereof to permit said members to be flexed
toward one another from an idle position in which they are
separated, each of said members having integral therewith at the
other end thereof an elongated flexible resilient jaw which
constitutes an extension of the member and which tapers in width
from the width of the member at said end to the tip of the jaw,
said jaws being flat from side to side, each said jaw being
disposed at an obtuse angle with respect to the member of which it
is an extension, said jaws having facing surfaces of substantially
matching configuration whereby the same are approximately parallel
in idle position of the members, the jaws being spaced apart in
idle position of the members, the longitudinal axes of one member
and its associated jaw defining one plane, the longitudinal axes of
the other member and its associated jaw defining a second plane,
said two planes being coincident, the central plane between the
members and the central plane between the jaws being inclined to
one another at said obtuse angle, so that when the jaws are moved
into engagement with one another by manual manipulation of the
members, the tips of the jaws will close upon opposite sides of the
common plane between the jaws to clamp the strands of a false
eyelash between them in order that the members, during application
of a false eyelash to an eyelid, will be in a plane perpendicular
to the length of the false eyelash strands and out of the line of
vision of the user, and the lengths of the jaws will be tangential
to the eyelid.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
An applicator for false eyelashes.
2. Description of the Prior Art
A feminine cosmetic adjunct that is coming into increasingly great
use is the artificial eyelash which originally was employed
principally by show people only, to create a more natural
appearance when viewed from a distance with stage lighting cast on
them. The lighting was so intense and the distance from which they
were viewed was so great that the delicate strands of a natural
lash became almost invisible, hence, the necessity for the
artificial lash. However, with the passage of years, and more so at
the present time, feminine makeup demands have been increasingly
emphasizing the utilization of false eyelashes to make up for the
sparseness of many natural lashes, to provide a dark lash where the
natural lash may be too light, to provide a longer lash where the
natural lash may be too short, to avoid the necessity of using
mascara and generally because with the increasing use of such
adjunct, false eyelashes have become a more or less accepted
standard of everyday feminine decor.
Essentially, a false eyelash consists of a flexible spine from
which strands of natural or synthetic hair extend, an end of each
strand being suitably secured in any of various manners to the
spine. Usually, the spine, as supplied to retail outlets, has a
curvature imparted thereto which roughly approximates the curvature
of a human eyelid. Obviously, the curvatures of various eyelids are
not identical so that, at best, the curvature of the spine is in
approximation and, indeed, the curvature of the spine at the retail
outlet generally is of a radius somewhat greater than any radius of
curvature likely to be found in an eyelid so that, customarily,
this radius of curvature of the spine must be reduced during the
application of the spine to a human eyelid above the natural
lashes. The spine is supplied with an adhesive coating, usually a
pressure sensitive adhesive coating, which enables it to be adhered
to an eyelid immediately above the lash line. In addition, adhesive
fluids are available to apply to the spine when the initial
adhesive becomes ineffective.
The basic problem with false eyelashes is that they are difficult
to apply. One method of applying them is with the use of an
individual's fingers. To do this, the individual closes the eyelid
of her eye on which the eyelash is to be applied, looks into a
mirror with her other eye and with her hands attempts to place the
adhesive side of the spine along her eyelid immediately above the
free edge of the eyelid which is immediately above her natural
lashes. This operation is actually quite difficult to practice. One
of the greatest difficulties is due to the monocular vision
involved during the application of the false lash. As is well
known, monocular vision creates an inaccurate perception of depth.
The individual cannot tell exactly where her hand is, or where the
artificial lash gripped by her hand is, in relation to her eyelid
in a front to back direction, this, despite the fact that she is
looking into a mirror. The difficulty of emplacement is enhanced by
the fact that the curvature of the spine exceeds the curvature of
her closed eyelid. Sometimes, she will place the center of the
artificial lash at the center of her eyelid immediately above the
natural eyelash and then try to force, first one side and then the
other of the false eyelash up against her eyelid--at all times her
accuracy of manipulation being lessened by her lack of accurate
depth perception.
Frequently, the spine slips vertically and will tend to adhere to
the eyelid in an improper vertical location. At other times she
will touch an end of the spine near an end of her eyelid and
gradually try to work her hands along the false eyelash and spine
to successively press succeeding increments of the spine against
her eyelid. Here too, she is hampered by her inaccurate perception
of depth which frequently causes the spine to move up and down as
it it being adhered to the lid. The results of a hasty application
are almost ludicrous so that it is not uncommon to see a woman who
is attempting to apply a false lash, rip the lash off time after
time until she arrives at an application which, although not
perfect, is to her then presently disgusted frame of mind
sufficiently good to leave alone.
Recognizing the extreme difficulty of manual manipulation, it has
been proposed to utilize implements to overcome the aforesaid
drawbacks. One implement is an ordinary pair of tweezers which is
essentially the same as a pair of hair removal tweezers. Sometimes
such tweezers have somewhat flattened tips to increase their area
of engagement with the false eyelash strands. To use these
tweezers, a person manipulates the tweezers in such a fashion that
the tips of the tweezers point directly toward the false eyelash
parallel to the strands. The shanks of the tweezers are linear
extensions of the tips and the shanks, therefore, likewise point
parallel to the false eyelash strands. Then, the user once again
looks into a mirror with the eyelid closed on the eye to which the
false eyelash is to be applied so that she is confronted with the
difficulty of monocular vision and its attendant disadvantage. The
user will either apply the center or an end of the adhesive spine
to the closed eyelid and then with her fingers attempt to force the
rest of the spine into contact with the eyelid to which it
hopefully adheres with sufficient force. The user will not
customarily use the tweezers to force successive parts of the false
eyelash against her eyelid because of fear of injuring her eye,
inasmuch as the tips of the tweezers are pointed directly at the
eye covered by the closed eyelid. This mode of application has been
frowned upon and not widely used due to its inherent disadvantages
above noted.
It also has been proposed to supply a pair of tweezers with tips in
the form of arcuate jaws which present a concave edge toward the
false eyelash strands to be engaged thereby. The planes of the
arcuate jaws were coincidental with the planes of the shanks of the
tweezer with which they were unitary. Such a modified form of
tweezer was better in that is obtained a firm grip on the false
eyelash strands. Nevertheless, it still did not prove to be a
practical instrument for several reasons, among which were the fact
that it necessitated the use of monocular vision during application
of the false eyelash and the fact that it tended, during handling,
to immobilize the curvature of the spine so that, remembering that
the natural curvature of the spine did not match the curvature of
most eyelids, the curved state of the spine held by such tweezers
did not correspond to the curvature of the eyelid and it was still
necessary to manually urge parts of the spine against the eyelid. A
tweezer with these arcuate jaws was not useful for this subsequent
urging step during which the spine had to be conformed to the
eyelid curvature.
Ancillary disadvantages of the both aforementioned tweezers were
that they did not obtain a good grip on the lashes and that if too
great a force were exerted on the shanks to improve the grip, the
tips or jaws of the tweezers tended to impart an angulation or a
crimp to the strands of the false eyelash.
Accordingly, the present state of the art is such that there still
is no good implement for convenient application of false eyelashes
to a human eyelid.
SUMMARY OF THE INVENTION
It is an object of the invention to provide an implement for
applying a false eyelash to a human eyelid which implement avoids
all of the foregoing drawbacks.
It is another object of the invention to provide an implement of
the character described which is so constructed as to permit
binocular vision during application of a false eyelash, in other
words an implement which is so constructed as to encourage
stereoscopic viewing of the eyelash during its application whereby
the user will have an accurate depth vision throughout the
installation process.
It is another object of the invention to provide an implement of
the character described which is so constructed that it minimizes
the danger of pushing the tip of the implement against the eye
inasmuch as the construction discourages handling of the implement
in such a manner that the tip is directed toward the eye, rather
the manipulation which is encouraged by such construction is one in
which the tip is tangential to the eye.
It is another object of the invention to provide an implement of
the character described which inherently will hold several strands
of the eyelash rather than just a few so that better control of the
eyelash can be maintained during its period of application.
It is another object of the invention to provide an implement of
the character described which is of such construction that it can
be readily manipulated to force against an eyelid those parts of
the spine of the false eyelash which were not initially pressed
against the eyelid during the period when the strands of the false
eyelash were firmly gripped between the tips of the implement.
It is an ancillary object of the invention to provide an implement
of the character described having a structure such that even when
the tips of the implement forcefully squeeze the strands of the
false eyelash, there is no tendency to impart an angular set or
crimp to said strands.
It is another object of the invention to provide an implement of
the character described through whose use women who have little
manual dexterity can quickly, accurately and nicely emplace false
eyelashes on their eyelids.
It is another object of the invention to provide an implement of
the character described through the use of which the entire length
of the spine can be firmly adhered to an eyelid so that during an
evening there is little chance of a part, for instance an end, of a
false eyelash becoming unanchored and springing away from the
eyelid in which position it will lend a ludicrous appearance to the
wearer.
It is another object of the invention to provide an implement of
the character described which constitutes relatively few and simple
parts, is capable of mass production and can be manufactured at a
low cost.
It is another object of the invention to provide an implement of
the character described, the use of which is immediately obvious
upon mere inspection of the implement so that no elaborate set of
instructions or training is necessary.
Other objects of the invention in part will be obvious and in part
will be pointed out hereinafter.
In general, the implement constitutes a pair of shanks and a pair
of jaws unitary with the shanks together with means for
manipulating the shanks so as to force the tips of the jaws against
one another, the tips in such position clamping many strands of a
false eyelash between them. The implement is characterized by the
fact that at least one of the tips is flexible and that the tips
are disposed at such angle to the shanks that when the tips are
moved into engagement by manipulation of the shanks, the tips will
close upon opposite sides of a plane which is at an angle to the
plane between the shanks. This in contradistinction to an implement
wherein shanks have jaws, the tips of which close upon manipulation
of the shanks, the jaws being at such angles with respect to the
shanks that the tips, when closed, close upon opposite sides of a
plane which is coplanar with the plane between the jaws. It is this
special angulation of the tips of the new implement which permit
its use in a fashion such that the jaws are tangential to an eyelid
to which a false eyelash is being applied and further causes the
implement to be out of the line of vision of the user so that the
implement can be employed for its intended purpose with both
eyelids raised so as to permit the user to enjoy binocular vision
and accurate depth perception during the installation of the false
eyelash.
The invention consists in the features of construction,
combinations of elements and arrangements of parts which will be
exemplified in the implements hereinafter described and of which
the scope of application will be indicated in the appended
claims.

PREFERRED EMBODIMENTS OF THE INVENTION
Referring now in detail to the FIGS., and, more particularly, to
FIGS. 1, 2 and 5, the reference numeral 10 denotes an applicator
constituting a preferred embodiment of the invention. The
applicator includes (see FIG. 5) a handle 12 in the shape of an
elongated cylindrical hollow tube having an open front end 14
which, for the sake of appearance, may be beveled, and a rear
closed end 16 which, again for the sake of appearance, may be
rounded. The handle can be made of any self-form-maintaining
material, e.g., metal or plastic.
The handle mounts a pair of shanks 18, 20, the shank 18 being fixed
to the handle and the shank 20 being slidable with respect to the
handle. The shanks 18, 20 likewise may be made from any
self-form-maintaining material, the material employed being one
which when sufficiently thin is flexible and resilient.
Satisfactory materials are metal and plastic. The shank 18 includes
a portion which extends deeply into the tubular handle and is fixed
rigidly thereto. The shank 20 likewise includes a portion which
extends well into the handle; however, this portion is slidable
relative to the handle. The shanks are elongated and their axes of
elongation are parallel to the longitudinal axis of the handle. As
illustrated, the shanks are of semicircular cross section, the
cross sections of the two shanks meeting adjacent and in the handle
to form a complete circle. The flats of the semicircular cross
sections are in planar juxtaposition and the movable shank 20 has
its flat in bearing engagement against the corresponding flat of
the fixed shank 18.
The movable shank 20 has secured thereto a manipulating knob 22
which is carried by that portion of the shank 20 which is disposed
within the tubular handle 12. The knob 20 is located within a
cutout or slot 24 formed in the handle to permit the knob 22 to
protrude therethrough for convenient manipulation of the shank
whereby by having a finger engaged on the knob 22, the shank 20 can
be shifted axially so as to move longitudinally with respect to the
fixed shank 18. The foregoing arrangement constitutes a means for
causing relative movement of the two shanks and, as soon will be
seen, relative movement of the jaws and tips of the shanks into and
out of mutual interengagement. The forward and rear edges of the
slot 24 constitute stop means for abutment of the knob thereagainst
to delimit movement of the shank 20 between a foremost extended
position shown in full lines in FIG. 5 and a rearmost retracted
position shown in dot-and-dash lines in the same FIG.
To enhance flexibility of the shanks, although this is not
necessary, and particularly to enhance flexibility of the forward
portions of the shanks, these forward portions may be of gradually
diminishing thickness in a direction perpendicular to the flats.
The same can be accomplished by flaring the flats slightly away
from one another as clearly indicated in FIG. 5.
Each shank carries a different jaw 26, 28, the jaw being stationary
and the jaw 28 being movable. It is a characteristic of the
invention that the jaws are at angles to their affiliated shanks.
The angulation is special. Specifically the orientation, i.e., the
plane of the angulation, is a feature of the present invention. The
angulation is such that when the jaws are moved into engagement by
manipulation of the shanks they close upon opposite sides of a
plane which forms a dihedral angle with the plane between the
shanks. This is to be contrasted, for instance, to a construction
wherein the jaws close upon one another on opposite sides of a
plane which is parallel to or coplanar with the plane between the
shanks, even if the tips happen to be angled in or parallel to such
a plane or planes. The degree of angulation, as distinguished from
the presence of a dihedral plane between the jaws and shanks is of
minor importance. Both jaws may be at the same angle to their
shanks; but in the preferred form of the invention the angles
between the jaws and shanks are almost but not quite the same.
Specifically, the jaw 26 is at an angle of 29.degree. to the
longitudinal axis of the shank 18 and the jaw 28 is at an angle of
32.degree. to the longitudinal axis of the shank 20. Hence, the two
jaws converge slightly toward one another in a direction toward
their tips. Typically the angle of conveyance is about 1.degree. to
about 5.degree. .
The thickness of the jaws, as seen in FIG. 5, tapers from the
shanks toward the tips so as to enhance flexibility of the tips.
Moreover, the width of the jaws tapers from the shanks toward the
tips as can be seen in FIG. 1 to further enhance flexibility of the
tips. Neither of these taperings is critical.
At least one of the jaws must be flexible in order that when the
jaws, which converge toward one another toward their tips, are
brought into mutual engagement by manipulation of the shanks the
jaws can bend sufficiently for the engaged parts to flex into
parallelism as shown in dot-and-dash lines in FIG. 5 whereby to
assure a substantial area of gripping. In the illustrated
embodiment of the invention both jaws are flexible.
In the operation of the applicator 10 the knob 32 is manipulated to
thrust the shank 20 forward so as to separate the jaws 26, 28 as
shown in solid lines in FIG. 5, then the opened jaws are approached
to an artificial eyelash, preferably to the center of the eyelash.
The applicator is so positioned with respect to the artificial
eyelash, which at this time may be in a carrier box, that the jaws
extend in a line perpendicular to the central lashes and are
located near the tips of these strands or about midway of the
lengths of the strands.
Because the spine of the artificial eyelash is curved the jaws will
extend over many of the strands of the eyelash but less than all,
specifically over the central strands but not over the endmost
strands so that the endmost strands are left free of the
applicator. This location of the applicator with respect to the
false eyelash is the preferred mode of operation but is not to be
construed as limitive of the invention.
Next, the applicator is manipulated so as to move the shanks in a
fashion such as to cause the jaws to mutually approach one another
and thereby clamp the aforesaid strands of the eyelash,
particularly at the center of the eyelash which they overlie. Thus,
there is at this time a firm engagement between the applicator and
the false eyelash.
Thereupon the eyelash can be lifted out of its carrier case. It
will be understood, of course, that the applicator can be caused to
engage the false eyelash even if it is not disposed within a
carrier case.
It will be appreciated that with the applicator so grasping the
false eyelash, the plane defined by the longitudinal axes of the
shanks and the elongated jaws is perpendicular to the longitudinal
axes of the eyelash strands. Hence the applicator extends laterally
away from the false eyelash, that is to say, to the side of the
false eyelash. Moreover, due to the angulation, the handle at this
time is below the false eyelash if the eyelash is held horizontally
with the handle generally disposed downwardly as shown in FIG.
1.
Now the false eyelash is applied to an eyelid. Application of one
of the eyelashes to one eyelid is illustrated in FIG. 1. At this
time, the applicator is held in the right hand of the user and it
is her left eyelid to which the false eyelash in being applied. The
shanks of the applicator cross over the bridge of the user's nose
at a rather high level depending, of course, upon the particular
configuration of the user's face. However, the plane defined by the
longitudinal axes of the jaws and shanks is roughly parallel to the
front of the user's face. Hence, the entire applicator as well as
the false eyelash about to be applied is located out of the line of
vision of the user who, at this time, can have stereoscopic viewing
and good depth perception of the applicator and the eyelash applied
by looking in a mirror. It will be seen from inspection of FIG. 1
and from an appreciation of the construction of the applicator that
the shanks after crossing the bridge of the user's nose descend
down below the right eye so as to be out of the right eye's line of
vision and that the jaws are above the open eyelid of the left eye
to which the false eyelash is being applied so that both eyes are
free to look into the mirror. The same will hold true of
application of a false eyelash to the right eye, except that there,
of course, the shanks will not cross the bridge of the user's
nose.
The instrument is symmetrical so that a left handed woman can use
it in the same manner but with her left hand holding the
handle.
The user with the applicator held as shown in FIG. 1 approaches the
false eyelash, specifically the spine of the false eyelash, and
even more specifically the pressure sensitive adhesive side of the
spine, to her eyelid with the center of the spine at the center of
her eyelid just above her lash line. It will be seen that at this
time the longitudinal axes of the jaws are substantially tangential
to her eyelid so that she will not be afraid of touching her eye or
eyelid with the somewhat narrow tips of the jaws. She then presses
the spine against her eyelid, actually the center of her eyelid,
which will cause the spine to adhere at this area to the eyelid.
Then she releases the false eyelash by moving the knob 22
rearwardly of the handle. It will be noted that with the specified
degree of angulation the forearm and elbow of the user will be
naturally positioned and not give rise to muscular stress or
fatigue.
Next, either with the jaws opened or with the jaws closed, by
further manipulation of the knob 22, she approaches the manipulator
to parts of the false eyelash between the now adhered center and
the ends of the eyelash so as to press successive parts of the
pressure sensitive area of the spine against her eyelid. She
continues to do this with the applicator until the false eyelash
adheres along its full length to the eyelid. It will be appreciated
that she has not had to use her hands at all, although she can if
she wishes, and that because of the unique construction of the
applicator, particularly the special angulation above referred to,
the applicator will not interfere with her line of vision while she
is thus adhering the remainder of the eyelash to her eyelid. All in
all, the operation is so rapid that it will be accomplished in far
less time than the reading of this segment of this
specificaton.
For the purpose of identification, in FIG. 2 the strands of the
false eyelash have been denoted by the reference numeral 30, the
spine by the reference numeral 32 and the adhesive coating by the
reference numeral 34. This FIG. also shows how the jaws of the
applicator clamp the strands between them.
If desired, the jaws 28 may be coated with a material which is
softer than the material of the jaws, such for instance as a thin
coating 36 (see FIG. 3) of rubber or polyvinyl chloride. This
minimizes any crimping or damage to the artificial strands 30
although there is very little danger of such damage because of the
flexibility of the jaws 26, 28.
Furthermore, if desired, and as illustrated in FIG. 4, the jaws 26,
28 may have their confronting surfaces configured to minimize
slippage of the jaws on an artificial eyelash when they grasp the
same (which is an additional purpose of the soft coating 36 as
shown in FIG. 3). As shown in FIG. 4, such configuration
constitutes a series of ribs 38 on the otherwise flat surfaces of
each of the jaws, i.e., facing surfaces, which ribs run
longitudinally of the jaws so that they appear as a series of
ripples in cross section, this being the view illustrated in FIG.
4.
In the applicator 10 described with respect to FIG. 1 through 5, a
specific means has been illustrated for manipulation of the shanks
in a fashion such as to move the jaws into and out of engagement
with one another under control of the user of the applicator.
Alternate means can be employed for the same purpose, two
constructions with different such means being disclosed in FIGS. 6
and 7.
Referring to FIG. 6 the shank 18' which is made of metal has a
portion thereof which is located internally of the handle 12'
welded thereto. A portion of the shank 20' which extends within the
handle 12' likewise is welded to the interior of the handle. The
welded portion of the shank 20' is located deep within the handle
so as to form a cantilever support for the shank 20'. The shank 20'
has fixed thereto a button 40 which extends through an opening 42
in the handle 12'. The shank 20' in released, i.e., idle,
condition, occupies a position in which it presses against an
interior sidewall of the handle 12'. However, by pressing the
button 40 inwardly to the dot-and-dash line position, it will cause
the flexible resilient shank 20' to swing toward the shank 18', as
shown in dot-and-dash lines, and this movement will close the jaw
28' onto the jaw 26', as shown in dot-and-dash lines, for clamping
engagement with the strands of a false eyelash which thereupon will
be manipulated in the fashion previously described.
In FIG. 7 both the flexible resilient shank 18" and the flexible
resilient shank 20" extend into the handle 12" where, as in the
case of the shank 20" in FIG. 6, they are welded at their free ends
deep within the handle so that each has a cantilever support
permitting the shanks to be flexed away from idle position in which
they are separated. The shanks 18" and 20" are embraced near the
handle 12" by a collar 44 which is a snug slidable fit on the
shanks. The portions of the shank somewhat forward of the handle
flare outwardly at a small angle, as shown in FIG. 7. Thereby when
the collar is slid forwardly on the shanks it will cause the shanks
to flex toward one another and this action will make the jaws (not
shown) interengage as shown in FIGS. 5 and 6.
It thus will be seen that there are provided applicators which
achieve the several objects of this invention and which are well
adopted to meet the conditions of practical use.
As various possible embodiments might be made of the above
invention and as various changes might be made for the embodiments
above set forth, it is to be understood that all matter described
herein or shown in the accompanying drawings is to be interpreted
as illustrative and not in a limiting sense.
