FIELD OF THE INVENTION
[0001] The present invention relates to a tool for eyelash extension. It also relates to
a method for extending eyelashes.
BACKGROUND OF THE INVENTION
[0002] Eyelash extension is used for enhancing the length of a person's natural eyelashes.
Extension elements, such as artificial eyelashes, are normally mounted to the eyelashes
to be extended one by one, using an adhesive to attach them individually. Conventionally,
an extension element is dipped in the adhesive and then directly attached to one of
the eyelashes to be extended. There are different types of adhesives available, and
a commonly used type is cyanoacrylate. Cyanoacrylate may cause skin irritation or
have other hazardous effects for both the person performing the eyelash extension,
and for the person whose eyelashes are being extended. Another drawback of dipping
the extension element in the adhesive, which is typically in its melted form, and
then attaching the extension element directly is that it is difficult to control the
amount of adhesive applied to the element.
SUMMARY OF THE INVENTION
[0003] It is an object of the present invention to alleviate at least some of the mentioned
drawbacks of the prior art and to provide an improved tool and a method for extending
eyelashes. This and other objects, which will become apparent in the following, are
accomplished by a tool and a method as defined in the accompanying independent claims.
[0004] The term exemplary should in this application be understood as serving as an example,
instance or illustration.
[0005] The present invention is based on the realisation that if the extension elements
are prepared by providing the adhesive and allowing it to bond to the extension element,
the amount of adhesive may be more easily controlled. By providing a tool comprising
a heating element, the adhesive attached to the extension element may then be melted
just before attaching the extension element to the eyelash to be extended.
[0006] According to a first aspect of the present invention, a tool for eyelash extension
is provided. The tool comprises a handle portion to be held by one hand, and a first
leg portion and a second leg portion for separating at least one eyelash from adjacent
eyelashes. The two leg portions extend from the handle portion and are held apart
by spring action. The tool further comprises a heating portion for melting an adhesive
attached to an extension element, said heating portion being attached to said handle
portion.
[0007] The handle portion may be made in one piece, or it may comprise a plurality of parts.
According to at least one exemplary embodiment, the handle portion may comprise a
first and a second handle part connected to each other in one end, like a tweezer.
The handle portion may suitably be made from a metallic and/or a plastic material.
[0008] The first leg portion and the second leg portion may suitably also be made from a
metallic and/or a plastic material. According to at least one embodiment the two leg
portions and the handle portion may be made in one piece, or they may be made from
separate parts which are attached to each other. By the two leg portions being held
apart by spring action is meant that when no external force is applied to the two
leg portions, they are held at a certain distance from each other, and when a force
is applied to both or one of the leg portions urging them to approach each other or
be brought further apart, the spring action works to return the leg portions to their
original position. This is advantageous from an ergonomic perspective for the person
performing the eyelash extension, since no force has to be applied to keep the eyelash
to be extended out of contact from the adjacent eyelashes once it has separated from
them.
[0009] By the heating portion being attached to said handle portion is meant that the heating
portion is arranged on or inside said handle portion. In some embodiments the heating
portion may be integrated into the handle portion, and in other embodiments the heating
portion may be external of the handle portion. The heating portion comprises at least
one resistor, preferably two resistors, for creating the heat. The heating portion
may further comprise additional resistors e.g. for regulating the temperature and
as disconnectors. A separate source of energy may be needed to heat the heating portion,
such as e.g. a battery or a cable for connecting the tool to a source of electricity.
[0010] According to an exemplary embodiment of the present invention, the two leg portions
are pointed. In other words, the two leg portions have a narrowing shape. This makes
it easier to separate at least one eyelash from the adjacent eyelashes.
[0011] According to an exemplary embodiment of the present invention, the tool has a length
of 8 - 20 cm, and/or the handle portion has a length of 6 - 18 cm, and/or the first
leg portion and the second leg portion have a length of 1 - 4 cm. The dimensions are
suitably adapted such that the tool may be held by one hand.
[0012] According to an exemplary embodiment of the present invention, the first leg portion
and the second leg portion are held apart 0.3 - 2 cm by said spring action. This distance
is suitable for separating the adjacent eyelashes from the eyelash to be extended
enough, such that the extension element or the adhesive is not in contact with any
of the other eyelashes while mounting it.
[0013] According to an exemplary embodiment of the present invention, the heating portion
is configured to be heated to a temperature of 80 - 150°C, preferably 110 - 130°C.
These temperature intervals are advantageous since the heating portion is to be used
to melt the adhesive attached to the extension element, and adhesives which are suitable
for eyelash extension typically have a melting point covered by these intervals.
[0014] According to an exemplary embodiment of the present invention, the two leg portions
are inclined in relation to said handle portion. In other words, the two leg portions
extend at an angle from said handle portion. The transition between the handle portion
and the two leg portions may be curved. Having leg portions inclined in relation to
the handle portion is advantageous since it enables the person performing the eyelash
extension to have a more ergonomic work position than if the two leg portions would
not be inclined.
[0015] According to an exemplary embodiment of the present invention, a surface of the heating
portion is U-shaped or V-shaped. An advantage of this is that it enables having a
more uniform distribution of heat, which will enhance melting of the adhesive.
[0016] According to an exemplary embodiment of the present invention, the heating portion
comprises at least two walls facing each other. By the two walls facing each other
is meant that the surface of each wall which is intended to be heated has a respective
surface normal, and the two respective surface normals intersect each other. This
also enables having a more uniform distribution of heat, which enhances the melting
of the adhesive.
[0017] According to an exemplary embodiment of the present invention, the heating portion
comprises a user protection cover made of a plastic material. This is advantageous
to prevent the user from burning while using the tool.
[0018] According to a second aspect of the present invention, a method for extending eyelashes
using a tool according to the first aspect of the present invention is provided. The
method comprises the steps of:
- providing an extension element provided with an adhesive,
- separating at least one eyelash to be extended from adjacent eyelashes using the first
and the second leg portions of said tool
- heating the adhesive attached to the extension element using said heating portion,
such that said adhesive melts,
- mounting the extension element to one of the eyelashes which has been separated out
by holding the extension element against the eyelash to be extended,
- fastening the extension element to the eyelash by adhering and solidification of said
adhesive.
[0019] In relation to this invention the term adhesive include compositions that may act
as bonding between the eyelash and the extension element, e.g. hot melts and waxes.
[0020] The method according to the second aspect of the present invention is a general method
which may be performed using other tools than a tool according to the first aspect
of the present invention.
[0021] The extension element may be any element suitable for attaching to an eyelash. Typically,
the extension element will be an artificial eyelash, but other types of extension
elements are also conceivable, such as for example feathers or other decorations.
[0022] The adhesive is an adhesive composition which may be heated such that it melts. The
adhesive composition may comprise a plurality of different components. The adhesive
may be provided on the extension element for example by dipping a portion of the extension
element in the adhesive while it is in its melted form. The adhesive is then allowed
to solidify e.g. while it cools, whereafter a desired amount of adhesive is attached
to the extension element. Preferably only a portion of the extension element is covered
with the adhesive, but in some embodiments the whole extension element may be covered.
[0023] By separating at least one eyelash to be extended from adjacent eyelashes is meant
that the eyelash to be extended should not be in contact with the adjacent eyelashes.
This is to avoid adhering the extension element to the adjacent eyelashes when mounting
it to the eyelash to be extended.
[0024] The step of heating the adhesive attached to the extension element using said heating
portion, such that said adhesive melts, is suitably performed by gripping the extension
element using a tool, such as a tweezer, and holding the extension element against
or above the heating portion. The temperature of the heating portion is suitably adapted
to the melting point of the adhesive, to enable melting of the adhesive.
[0025] When mounting the extension element to one of the eyelashes which has been separated
out, the extension element is suitably still gripped with tool such as a tweezer.
Once the step of fastening the extension element by solidifying of said adhesive has
been performed, the extension element may be released from the tweezer. Due to the
solidifying which results in a bonding of the adhesive, the extension element will
then stay attached to the eyelash to be extended.
[0026] According to an exemplary embodiment of the second aspect of the present invention,
the extension element comprises at least one artificial eyelash. In some exemplary
embodiments, the extension element may comprise a strand or a bundle of artificial
eyelashes. The artificial eyelashes may suitably be made of a synthetic material,
or they may be made of hair. Other types of extension elements are also conceivable,
such as feathers or other decorations of different materials and shapes.
[0027] According to an exemplary embodiment of the second aspect of the present invention,
the adhesive is a composition selected from a group comprising: hot melts, low temperature
melting hotmelts waxes such as microcrystalline waxes and combinations thereof. For
hot melts including low temperature melting hotmelts (such as ethylene vinyl acetate
polymer) and micro crystalline waxes the bond to the lash is established upon solidification.
Low temperature melting hotmelts and waxes are advantageous as they melt to liquid
form at temperatures which is safe to use close to the human eye.
[0028] According to an exemplary embodiment of the second aspect of the present invention,
said composition also comprises:
- a) one or more pigments, wherein preferably said one or more pigments is carbon black.
[0029] Using one or more pigments in the composition may be beneficial to reduce the visibility
of the adhesive, such that the extension looks more natural.

DETAILED DESCRIPTION OF EMBODIMENTS
[0031] In the following detailed description, some embodiments of the present invention
will be described. However, it is to be understood that features of the different
embodiments are exchangeable between the embodiments and may be combined in different
ways, unless anything else is specifically indicated. Even though in the following
description, numerous specific details are set forth to provide a more thorough understanding
of the present invention, it will be apparent to one skilled in the art that the present
invention may be practiced without these specific details. In other instances, well
known constructions or functions are not described in detail, so as not to obscure
the present invention.
[0032] Figure 1 illustrates use of a first exemplary embodiment of a tool for eyelash extension
according to the first aspect of the present invention. The same tool is also illustrated
in Figure 2. The tool 1 comprises a handle portion 2, which is adapted for being held
by one hand. The handle portion 2 of this exemplary embodiment comprises a first handle
part 21 and a second handle part 22 connected to each other in one end, like a tweezer.
From the first handle part 21, a first leg portion 31 extends. A second leg portion
32 extends from the second handle part 22. The two leg portions 31, 32 are used for
separating at least one eyelash 12 from the adjacent eyelashes, and they are being
held apart by spring action. In this embodiment, the spring action is arranged between
the first 21 and the second handle parts 22. The first leg portion 31 and the second
leg portion 32 are held apart 0.3 - 2 cm by the spring action. In other words, when
no external force is applied to the tool 1, the distance between the tip of the first
leg portion 31 and the tip of the second leg portion 32 is 0.3 - 2 cm. When a compressional
force is applied to the handle portion 2 and/or to one or both of the leg portions
31, 32, in a direction urging the leg portions 31, 32 towards each other, the distance
between the tip of the first leg portion 31 and the tip of the second leg portion
32 decreases. When the force is removed, the tool 1 will return to its original state
with 0.3 - 2 cm between the first leg portion 31 and the second leg portion 32.
[0033] The first leg portion 31 and the second leg portion 32 extend at an angle from the
handle portion 2. In other words, the first leg portion 31 and the second leg portion
32 are inclined in relation to the handle portion 2. In the illustrated exemplary
embodiment, the first leg portion 31 and the second leg portion 32 are partially curved.
The first leg portion 31 and the second leg portion 32 are in this embodiment also
pointed, to make it easier to separate the eyelash to be extended from the adjacent
eyelashes.
[0034] In the illustrated exemplary embodiment, the first leg portion 31 and the first handle
part 21 are made in one piece, and the second leg portion 32 and the second handle
part 32 are made in one piece. In other exemplary embodiments, the two leg portions
31, 32 and the handle parts 21, 22 of the handle portion 2 may be made from separate
pieces which are attached to each other. The leg portions 31, 32 and the handle portions
21, 22 are in this embodiment made from a metallic material, but they may also be
made from a plastic material, or a combination thereof.
[0035] The tool 1 further comprises a heating portion 4 attached to the handle portion 2.
In this exemplary embodiment, the heating portion 4 is integrated in the first handle
portion 21. This makes the tool 1 compacter and easier to hold compared to if the
heating portion 4 is not integrated. The heating portion 4 is adapted for melting
an adhesive 11 attached to an extension element 10. In the exemplary embodiment, the
heating portion 4 comprises two resistors for creating heat, one resistor for regulating
the temperature, and one resistor as a disconnector. A cable 5 runs from the first
handle part 21, for connecting the tool 1, i.e. the heating element 4, to a source
of electricity.
[0036] The heating portion 4 has a surface 40 which in this embodiment is V-shaped. This
V-shaped surface 40 is the part of the heating portion which is to be heated. The
surface 40 comprises two walls 41, 42 facing each other. When using the heating portion
4 to melt the adhesive 11 attached to the extension element 10, the part of the extension
element 10 covered by the adhesive 11 is suitably held above the surface 40, and/or
at least partly between the two walls 41, 42 facing each other.
[0037] The heating element 4 is configured to be heated to a temperature within a range
of e.g. 100°C - 120°C. This is suitable for the adhesive 11 used together with this
embodiment, which will be further described below. In other embodiments, other temperatures
may be used. The temperature of the heating element 4 is adapted to the melting point
of the adhesive 11 to be melted.
[0038] The 1 tool according to the illustrated exemplary embodiment has a length of 8 -
20 cm. The handle portion 2 has a length of 6 - 18 cm, and the first leg portion 31
and the second leg portion 32 have a length of 1 - 4 cm. Other embodiments may have
other dimensions, but the dimensions should suitably be adapted for the tool 1 to
be held by one hand.
[0039] Fig. 3 shows a second exemplary embodiment of a tool 1' according to the first aspect
of the present invention. This second exemplary embodiment has a handle portion 2'
comprising a first handle part 21' and a second handle part 22', similarly to the
first exemplary embodiment. The tool 1' also has a first leg portion 31' and a second
leg portion 32', which also have the same properties as those of the first exemplary
embodiment. The tool 1' according to the second exemplary embodiment differs from
the first exemplary embodiment in that the heating portion 4' is different. In this
second exemplary embodiment, the heating portion 4' is not integrated in the handle
portion 2', but is attached to the outside of the first handle part 21' of the handle
portion 2'. The heating portion 4' also has a V-shaped surface 40', with two walls
41', 42' facing each other. In this second exemplary embodiment, the surface 40' of
the heating element 4' is larger than the surface 40 of the heating element 4 according
to the first exemplary embodiment. This may be beneficial since it may be easier to
melt the adhesive 11 when the heat is distributed over a larger area. The heating
portion 4' in this embodiment also comprises a user protection cover 45 made of a
plastic material, to prevent the user from burning when holding the tool. A cable
5' runs directly from the heating portion 4' for connecting it to a source of power.
[0040] The heating portion 4' according to the second exemplary embodiment may be retrofitted
to a tool having a handle portion 2' and two leg portions 31', 32', or the tool 1'
may be provided as a whole.
[0041] Fig. 4a - 4c show an exemplary embodiment of a method according to the second aspect
of the present invention, using a tool 1 according to the first exemplary embodiment
illustrated in Figure 1 and Figure 2. In Fig. 4a, an extension element 10 provided
with an adhesive 11 is provided. In this particular embodiment, the extension element
10 comprises an artificial eyelash, which is partially provided with an adhesive 11.
According to this non-limiting example the adhesive 11 is Polycaprolactone Capa 6250
with a melting temperature of 60° C, where the bond to the lash is established upon
solidification.
[0042] The method further comprises a step of separating at least one eyelash to be extended
12 from adjacent eyelashes, which is also illustrated in Fig. 4a. This is done using
the first and the second leg portions 31, 32 of the tool 1. Once the eyelash to be
extended 12 has been separated out, the portion of the extension element 10 covered
in the adhesive 11 is held just above the surface 40 of the heating portion 4, such
that the adhesive 11 is heated to a temperature where it melts. This is illustrated
in Fig. 4b.
[0043] In fig. 4c, the extension element 10 is mounted to one of the eyelashes which has
been separated out by holding the extension element 10 against the eyelash to be extended
12. In this embodiment, the extension element 10 is held with a tweezer 6. It is held
in place against the eyelash to be extended 12 until the adhesive 11 has cured such
that the extension element 10 is fastened. The tweezer 6 can then be removed, and
the extension element 10 is attached to the eyelash to be extended 12.
[0044] The person skilled in the art realizes that the present invention by no means is
limited to the embodiments described above. The features of the described embodiments
may be combined in different ways, and many modifications and variations are possible
