This application claims priority to Korean Patent Application No. 10-2019-0109457 (filed on Sep. 4, 2019), which is incorporated herein by reference in its entirety.
The present invention relates to artificial eyelashes for extension, and more particularly, to artificial eyelashes for extension, in which the artificial eyelashes may be simply attached and a difficult process of applying adhesives to eyelashes of a person to be treated during an eyelash extension procedure may be omitted so as to significantly improve working efficiency and to perform high-quality treatment.
Generally, in a cosmetic aspect, eyelashes are very significant. Particularly, women generally prefer long and curled upward eyelashes the most and form such eyelashes using mascara.
The mascara corresponds to the simplest method of performing a function of first properly forming a shape of eyelashes and applying black color to the made-up eyelashes and is in general use. A method of using mascara is basically applied to long eyelashes so that more aesthetic eyelashes may be made.
However, in the case of short eyelashes, aesthetics have been improved using a method of extending eyelashes by attaching additional artificial eyelashes. Artificial eyelashes include an eyelash portion including a plurality of eyelash strands and a base portion configured to tie up and support the eyelash strands. Here, the artificial eyelashes are attached to real eyelashes on an eyelid by applying an adhesive to the base portion.
Since it is necessary for a user to directly and precisely attach the artificial eyelashes to the eyelid, when the user is not skilled, there is a disadvantage that a large amount of time is consumed in attachment which is very inconvenient.
To overcome the above disadvantage, an attachment tool capable of easily attaching eyelashes has been disclosed in Korean Utility Model Registration No. 165452. However, since the above artificial eyelashes provide excellent makeup but are used as a disposable product, there is a disadvantage of attaching new artificial eyelashes whenever necessary. Also, there is a disadvantage of carrying artificial eyelashes outdoors.
Meanwhile, in the case of short eyelashes, in addition to the artificial eyelashes, an eyelash extension method is present. The eyelash extension method is generally performed in skin care shops or hair salons and has an advantage of forming long eyelashes by attaching extending eyelashes using an adhesive and has an advantage of maintaining a treated state for several months after treatment. Related thereto, some related arts have been disclosed.
For example, Korean Patent Publication No. 10-2005-0094973 (Sep. 29, 2005) discloses a method of having eyelashes permed. The above method includes attaching extending eyelashes and setting an entirety of eyelashes and has an advantage of reducing a time of applying makeup to eyelashes by simply using mascara to make eyelashes black after perm and has an advantage of maintaining a treated shape for a relatively long time after one time treatment.
However, in the case of the above extension method, since all operations are manually performed one by one, a large amount of time is necessary and high-level of skill is needed. Particularly, since a process of attaching artificial eyelashes to real eyelashes using an adhesive is a complicated operation that should be most delicately performed, the process cannot be performed at once and it is necessary to perform the process in parts over several procedures. Additionally, according to the above related art, there is a crucial problem that a risk of nearly damaging an eyeball of a person to be treated is high.
The present invention is directed to providing artificial eyelashes for extension capable of significantly improving working efficiency and performing high-quality treatment by omitting a complicated process of applying an adhesive to eyelashes of a person to be treated and simply attaching the artificial eyelashes during an eyelash extension procedure.
According to an aspect of the present invention, there is provided artificial eyelashes for extension, which are configured to be attached to eyelashes of a person to be treated to extend a length of the eyelashes. The artificial eyelashes include a bonding member provided on a point spaced apart from a vicinity of root portions of eyelash strands, configured to be a solid member attached to the eyelash strands at room temperature, and melted with viscosity to bond the eyelash strands to the eyelashes of the person to be treated when heat at a certain temperature or higher is applied.
The bonding member may be a linear member provided to be parallel, with a gap therebetween, to a base configured to connect the root portions of the eyelash strands. The bonding member may be attached to a front or a rear of the eyelash strands while protruding therefrom. The bonding member may be provided to have a length which exceeds a region in which the eyelash strands are arranged such that ends thereof may protrude leftward and rightward. The bonding member is configured to be melted at a temperature of 90° C. to 130° C.
The bonding member may include ethylene-vinyl acetate (EVA) copolymer as a major material having the highest content. A pigment for imparting color may be further added, as an additive, to the bonding member. The vitamin A, vitamin C, vitamin E, and peptides may be added to the bonding member to be absorbed into the eyelashes of the person to be treated when the bonding member is heated and melted.
To correspond to an exclusive shield for the artificial eyelashes, which is divided into an upper body and a lower body so that front ends thereof form one pair and are opened or closed to clasp the eyelashes of the person to be treated while an extension operation of adding the artificial eyelashes to the eyelashes of the person to be treated to extend a length thereof and which includes an accommodation groove having a concave curve to accommodate a protruding eyeball of the person to be treated with an eye being closed in a front of the front end while facing the eyeball and being in contact with an eyelid of the person to be treated and includes a safety cover behind the accommodation groove and having a working space with a rearward-opening inlet to accommodate the eyelashes of the person to be treated which are clasped between the front end of the upper body and the front end of the lower body and protrude, the bonding member may be spaced at a distance of 1.0 to 5.0 mm apart from the root portions of the eyelash strands to be located in the working space provided in the safety cover of the shield when the front end of the upper body and the front end of the lower body of the shield clasp the eyelashes of the person to be treated and the root portions of the eyelash strands together. The accommodation groove of the shield may be formed to have a depth of 13.15 to 15.36 mm, a lateral width of 32.44 to 36.05 mm, and a longitudinal length 32.59 to 36.21 mm, and the bonding member may be formed to have a lateral width less than the lateral width of the accommodation groove so as to be accommodated in the working space of the safety cover through the accommodation groove of the shield.
The front of the front end where the accommodation groove of the shield is formed may have a curvature radius of 21 to 22 mm, and the bonding member may be formed as a curve corresponding to the curvature radius of the accommodation groove of the shield.
The above and other objects, features and advantages of the present invention will become more apparent to those of ordinary skill in the art by describing exemplary embodiments thereof in detail with reference to the accompanying drawings, in which:

As shown in the drawings, artificial lashes 300 for extension according to one embodiment of the present invention are configured to be added to eyelashes of a person to be treated so as to extend a length thereof and include a plurality of eyelash strands 310, a base 320 configured to connect root portions 310a of the eyelash strands 310 in a row, and a bonding member 330.
The bonding member 330 is a linear member provided to be parallel with a space from the base 320 which connects the root portions 310a of the eyelash strands 310. The bonding member 330 is provided as a solid member at a room temperature while being attached to the eyelash strands 310, is melted when heat at a temperature within a range of 90° C. to 130° C., and more particularly, about 110° C., is applied and solidified again so as to have high bonding property. To this end, when the bonding member 330 is heated using grips 210 of a thermal bonding device 200 shown in
Here, the bonding member 330 includes ethylene-vinyl acetate (EVA) copolymer as a major material having the highest content. Due to high bonding property at a high level melted state and excellent pliability, shock resistance, stress resistance, and cracking property, EVA is very appropriate for a material of the bonding member 330. The bonding member 330 formed of the above EVA material performs a function as an adhesive when being heated and melted and performs a function of holding and supporting the eyelash strands 310 with the root portions 310a connected in a row by the base 320 in an aligned state to more stably maintain the aligned state before being melted. In addition, the bonding member 330 may be formed to be a natural curve fitting in with eyelashes instead of a straight line so as to support the eyelash strands 310. While elasticity is provided by the above EVA material, even when an external force or a shock is applied, an original form is immediately restored and it is possible to continuously maintain the aligned state of the eyelash strands 310. Here, in order to compensate for a function of elasticity and the like which may be insufficient with EVA alone, a small amount of some additives may be added.
Also, a small amount of pigment for imparting color is added to the bonding member 330 as an additive. Since the bonding member 330 may have any colors which are equal or similar to a color of the eyelash strands 310 so as to be naturally harmonized with the eyelash strands 310 of the artificial eyelashes 300 and the eyelashes of the person to be treated while being melted and flowing thereinto, eco-friendly pigments or cosmetic pigments which have no harm to the skin or eyes may be used. In addition, vitamin A, vitamin C, vitamin E, and peptides are added to the bonding member so as to be absorbed by the eyelashes of the person to be treated when the bonding member is heated and melted. According to the above bonding member to which vitamin A, vitamin C, vitamin E, and peptides are added, the eyelashes of the person to be treated which are partially damaged while receiving high-temperature heat due to the eyelash extension procedure are helped in reproducing at a high speed.
Observing a shape of the bonding member 330 closely, as shown in a cross-sectional view of
According to the bonding member 330 attached to the front of the eyelash strands 310 instead of the rear while protruding therefrom, when the eyelash strands 310 are overlapped with the eyelashes of the person to be treated to be bonded thereto, it is possible to secure an adequate amount of adhesive while the bonding member 330 is melted without being interrupted by the bonding member 330.
One of very significant aspects of the artificial eyelashes 300 for extension according to one embodiment of the present invention is a shape corresponding to an exclusive shield 100 (refer to
As described above, the artificial eyelashes 300 for extension according to one embodiment of the present invention significantly enhance working efficiency in treatment of extending eyelashes and perform high-quality treatment using the exclusive shield 100 which will be described below in detail with reference to
First, as shown in
Subsequently, when the thermal bonding device 200 is operated by pushing a switch thereof while a pair of grips 210 of the thermal bonding device 200, which is heated at a high temperature, are located on both sides of the bonding member 330, as shown in
Subsequently, when the grips 210 of the thermal bonding device 200 are removed, the liquid-type bonding member 330 which has permeated into the gaps between the eyelash strands 310 and the eyelashes HR of the person to be treated with viscosity while being melted is solidified again at room temperature so as to very stably bond the eyelash strands 310 to the eyelashes HR of the person to be treated as shown in
Subsequently, an eyelash extension system including the exclusive shield for the artificial eyelashes for extension and the thermal bonding device according to one embodiment will be described below.
As shown in the drawings, the exclusive eyelash extension system for artificial eyelashes for extension according to one embodiment of the present invention includes the shield 100 and the thermal bonding device 200 to perform a series of operations of extending eyelashes of a person to be treated by bonding the artificial eyelashes 300 thereto.
It should be noted that it is possible to comfortably and safely protect an eyeball with the shield 100 ergonomically designed in consideration of a protruding level of the eyeball and a lateral width and a longitudinal length of an eye socket of the person to be treated and to significantly improve working efficiency by simplifying an eyelash extension operation.
Hereinafter, the exclusive eyelash extension system for artificial eyelashes for extension according to one embodiment of the present invention will be described in detail around the shield 100.
As shown in
The safety cover 110 is formed as a container-shaped body having an open rear side. The body is configured to be divided into the upper body 110a and the lower body 110b and front ends thereof form a pair to be opened or closed so as to clasp the eyelashes of the person to be treated.
The safety cover 110 includes the accommodation groove 111 in a front of the front end, which is formed as a concave curve to accommodate a protruding eyeball of the person to be treated with an eye being closed while facing and being in contact with the eyelid. The above accommodation groove 111 is ergonomically designed, on the basis of verified materials, in consideration of protruding levels of eyeballs and lateral widths and longitudinal lengths of eye sockets of Asians or Westerners to have a depth of 13.15 to 15.36 mm, a lateral width of 32.44 to 36.05 mm, and a longitudinal length of 32.59 to 36.21 mm. Also, as shown in
In the safety cover 110, behind the accommodation groove 111, there is provided a working space 112 having a rearward-opening inlet to perform an extension operation and a finishing operation while accommodating the eyelashes clasped between the front end of the upper body 110a and the front end of the lower body 110b and protruding rearward. Here, the safety cover 110 is formed to have a shape in which a longitudinal length and a lateral width gradually increase from the front end toward a rear end such that the working space 112 is formed to gradually increase toward the inlet. When the working space 112 is formed to increase toward the inlet, as shown in a photo of
To allow the safety cover 110 to be divided into the upper body 110a and the lower body 110b such that the front ends thereof form one pair to be opened or closed, an upper extending portion 113a and a lower extending portion 113b which extend rearward are formed on left and right lower sides of the rear end of the upper body 110a and left and right lower sides of the rear end of the lower body 110b. Also, the upper extending portion 113a and the lower extending portion 113b are pivotably hinge-coupled with support portions 121 provided on left and right sides of the support frame 120 using hinge shafts 114a and 114b. The upper extending portion 113a and the lower extending portion 113b may include a matching protrusion 117a and a matching groove 117b for matching as shown in
Meanwhile, a division line which divides the body into the upper body 110a and the lower body 110b traverses the front of the front end, which forms the accommodation groove 111 of the safety cover 110 in a vertically divided shape and continues to an end of a side surface of the safety cover 110.
In the safety cover 110, an upper lever 115a and a lower lever 115b, which have protrusion shapes respectively extending upward and downward, are provided on a top of the rear end of the upper body 110a and a bottom of the rear end of the lower body 110b. Hereby, as shown in
The support frame 120 is installed in a position spaced rearward apart from the safety cover 110 and is formed to have a quadrangular ring shape along a perimeter part of the inlet of the working space 112 of the safety cover 110. Also, as described above, the support portions 121 are formed on the left and right sides of the support frame 120 and extend forward with hinge shafts 114a and 114b on the left and right lower sides of the rear end of the upper body 110a and the left and right lower sides of the rear end of the lower body 110b being pivotable.
The springs 130a and 130b may be formed as coil-shaped compression springs 130a and 130b as shown in
Immediately after the eyelash strands 310 and the eyelashes of the person to be treated temporarily adhere to each other while being partially overlapped with each other with the bonding member 330 of the artificial eyelashes 300 for extension therebetween, the above-described shield 100 for eyelash extension clasps a region in which the root portions 310a of the eyelash strands 310 and the eyelashes of the person to be treated are overlapped with each other at the same time and is attached to an eyelid. Here, it is necessary to clasp the region such that the bonding member 330 is completely located in the working space 112 of the shield 100. When the shield 100 is precisely attached to the eyelid of the person to be treated, the artificial eyelashes 300 for extension and the eyelashes of the person to be treated are bonded to each other by heating and melting the bonding member 330 using the grips 210 of the thermal bonding device 200. Here, since the shield 100 attached to the eyelid of the person to be treated safely protects the eyeball from the grips 210 at a high temperature and clasps the eyelashes and the artificial eyelashes 300 for extension with a width adequate for completely accommodating a lateral width of the eye socket of the person to be treated, it is unnecessary to add and heat the artificial eyelashes 300 piece by piece and it is possible to perform a thermal bonding operation at once.
Subsequently, while the shield 100 is bonded to the eyelid of the person to be treated, a finishing operation of removing residual adhesives using simple tools and trimming the extended eyelashes may be performed.
As shown in
According to the embodiments of the present invention, when eyelash extension procedure is performed using artificial eyelashes for extension including a bonding member melted with viscosity when heat at a certain temperature or higher is applied and configured to bond eyelash strands to eyelashes of a person to be treated, working efficiency can be significantly improved and high-quality treatment can be performed by omitting a complicated process of applying an adhesive to the eyelashes of the person to be treated and simply attaching the artificial eyelashes.
Due to the bonding member having elasticity, even when a shock or an instantaneous external force is applied, an aligned state of the eyelash strands can be stably maintained. The artificial eyelashes are optimized for an exclusive shield thereof such that it is possible to safely and conveniently performing the eyelash extension procedure.
Although exemplary embodiments of the present invention have been described above, a variety of changes, modifications, and equivalents of the present invention may be used. It is apparent that the embodiments of the present invention may be adequately modified and equally applied. Therefore, the above description is not intended to limit the scope of the present invention which is defined by the following claims.
