TONGS FOR HANDLING FALSE EYELASHES
Abstract
A tongs having an integral molded hinge joining a pair of legs,
each leg having a crosspiece at its outer end, the crosspieces
being curved to grasp the lashes of a false eyelash and to exert an
even pressure on all the lashes when the crosspieces flex under
closing forces, the legs having interlocking tongue-and-groove
elements to prevent relative sliding of the crosspieces.

Claims
I claim:
1. A device for holding a false eyelash having a spine from which a
plurality of lashes project, said device comprising
a. an upper jaw;
b. a lower jaw;
c. means for moving the jaws toward each other;
d. an upper gripping surface on said upper jaw;
e. a lower gripping surface on said lower jaw movable into
juxtaposition to said upper gripping surface when said jaws are
brought together; said upper and lower gripping surfaces defining
between them, when in juxtaposition, a lash-receiving slot;
f. at least one gripping surface having an arcuate outer edge
substantially equal in radius to the margin of a human eyelid, said
outer edge defining an edge plane in which it is located;

Description
BACKGROUND OF THE INVENTION
False eyelashes are comprised of a cordlike spine from which a row
of lashes or hairs projects. Such false eyelashes are attached to
the eyelids by a bead or strip of adhesive which is applied by the
wearer to the spine before putting the false eyelashes in place on
her eyelids.
Correct handling of the false eyelash is difficult for many
wearers. It is small and flexible. Placement on the eyelid is done
with a mirror while the eye in question is closed. It is an object
of the invention to provide an inexpensive tongs with which the
false eyelash may be more easily manipulated than is presently
possible when using the fingers alone.
SUMMARY OF THE INVENTION
The invention comprises a tongs which is molded in one piece of
polypropylene. The legs of the tongs can be joined by a molded-in
hinge section so that hinge barrels and pintles are unnecessary.
The outer end of each leg has a crosspiece shaped to grasp the
lashes or hairs of the false eyelash and to hold it in a position
which is convenient for application to the eyelid.
The design incorporates several features necessitated by the
flexibility of the plastic material employed and the requirements
of holding the false eyelash. The hinge is long in order to avoid
as far as possible misalignment of the ends of the legs. For the
same purpose a tongue-and-groove arrangement is provided on opposed
surfaces of the two legs. The legs are of U-shaped cross section
for rigidity, and the abutting surfaces of the crosspieces are
molded with different radii of curvature so that when flexed by the
finger pressure of the user they exert a constant gripping force on
the lashes at all points along their length.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a plan view of the tongs closed about a false
eyelash;
FIG. 2 is a side view of the tongs in use;
FIG. 3 is a side view of the open tongs in cross section;
FIG. 4 is a plan view of the inside of the tongs with the legs
extended in opposite directions; and
FIG. 5 is a front view of the tongs in closed position as seen by
the user as it approaches the user's face.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The tongs 10 is a unitary structure molded of polypropylene. It is
comprised of an upper leg 11 and a lower leg 12 connected by a
flexible web 13 which serves as a hinge. In order to insure that
the legs come together with precision, the web is relatively long;
as shown it is approximately two-thirds as long as a leg of the
tongs. As a further means of insuring that the ends of the legs
meet properly the lower leg 12 bears a tongue 14 which projects
into the space between the legs. Two ridges 15, 15 form a groove
between them into which the tongue 14 projects as the legs come
together.
Each leg of the tongs is of U-shaped cross section, with side
flanges 16, 16 and 17, 17 serving to strengthen the upper and lower
legs, respectively.
An upper crosspiece 18 on the upper leg abuts a lower crosspiece 19
on the lower leg when the tongs are closed. An arcuate edge 20 on
the upper crosspiece is aligned with an arcuate surface 21 on the
lower crosspiece when the tongs is closed. The radii of the edge
and the arcuate surface is approximately that of the lower margin
of the human eyelid (or of the spine of a false eyelash when in
place), so that the spine of a false eyelash held by the tongs is
properly shaped to adhere to the eyelid at all points along its
length.
The false eyelash 22 is comprised of a cordlike spine 23 and hair
like lashes 24 which project at right angles therefrom in a common
direction. The crosspieces of the tongs grip the lashes 24 between
them, the lower crosspiece having a concave lower gripping surface
25 and the upper crosspiece a convex upper gripping surface 26. The
provision of a slight concavity and convexity to these surfaces
allows them to grip the lashes 24, which usually curve upward at
their outer ends, without straightening them from their curved
shape. The upper gripping surface 26 is also provided with shallow
furrows in a cross-patch pattern to increase its grip on the
lashes.
The edge 20, and the mating edge of arcuate surface 21, are arcs,
and each establishes an "edge plane," which may be defined as the
plane in which the edge lies. During the normal use of the tongs
when the spine of the false eyelash is in contact with the margin
of the eyelid the edge planes will be parallel and roughly
horizontal, while the legs of the tongs extend down and away from
the face at about a 45.degree. angle to said planes. This angle is
a convenient one for a finger grip on the tongs. In addition, it
locates the legs of the tongs and the user's hand below the
horizontal line of sight between the eyes of the user and a
vertical mirror in front of the user's face.
While the spine of the false eyelash is held in an arc which lies
in a substantially horizontal edge plane during application (see
FIG. 2), the lashes will extend downward from the spine, rather
than outward in a horizontal direction (see the angle of surface 25
in FIG. 2). The shape of the gripping surfaces thus position the
lash properly for application.
The use of crosspieces at the ends of the legs of the tongs allows
the tongs to grip a false eyelash along substantially the whole
length of the spine, while at the same time minimizing the
obstruction to the user's view caused by the presence of the
tongs.
Because of the flexibility of the polypropylene used in the tongs
the gripping surfaces 25 and 26 might fail to get an even grip on
the lashes if said surfaces were congruent surfaces when not under
strain. Instead the upper gripping surface 26 has a smaller radius
of curvature than the lower gripping surface 25. As these surfaces
approach each other their outer ends meet first; as further finger
pressure is applied they flex so that they also meet in the middle.
This structure avoids the effect which would be achieved if both
surfaces were flat or if both had the same radius of curvature;
i.e., a stronger gripping of the lashes in the center of the false
eyelash than of those near the ends.
The interlocked tongue 14 and ridges 15, 15 not only guide the legs
of the tongues into proper engagement, as described above, but
serve to hold the crosspieces located at their outer ends against
sideways slippage relative to each other while so engaged. Such
slippage, which otherwise might occur, would tend to roll the hairs
of the false eyelash between the crosspieces, damaging them or
altering their curvature. Thus, the tongue 14 and ridges 15, 15
compensate for the lack of rigidity which is inherent in the use of
polypropylene for the legs and the hinge.
When the tongs if formed with the legs separated, as for example in
FIG. 4, sufficient springiness remains in the web 13 to open the
legs as shown in FIG. 3, when finger pressure is released. This is
an advantage in using the tongs to pick up a false eyelash.
The tongs described is adapted to inexpensive production by means
of plastic injection molding techniques. It enables the user to
hold a false eyelash securely while coating its spine with adhesive
and while fixing it to the eyelid. The tongs is simple, easy to
clean, and free of dangerous projections. The structure of the
crosspieces is adapted to hold a false eyelash without injuring it,
and to present it to the eyelid at the proper angle when the
handles of the tongs are held at the natural angle to the face,
i.e., sloping down and away at approximately a 45.degree. angle as
shown in FIG. 2.
