Abstract

Artificial eyelashes according to the present invention are characterized in that an artificial eyelash (122) has a rectangular transverse cross-section of which at least one pair of sides facing each other are recessed. Here, it is preferred that the upper and lower sides of the rectangle are recessed, and a relationship of 0.4 x t1 < t2 < 0.8 x t1, t1 ≤ w1 ≤ 1.5 x t1 is satisfied, where w1 denotes the width of the rectangle, t1 denotes the thickness thereof, and t2 denotes the smallest thickness between the recessed portions of the upper and lower sides. The artificial eyelash is preferably tapered at one end portion (122a) thereof to have a gradually decreasing thickness toward the distal end thereof, and the end portion (122a) is preferably divided into left and right parts. According to the present invention, a natural eyelash is smoothly guided to the middle of the recessed portion of the artificial eyelash so that the natural eyelash can always be reliably attached to a predetermined location of the artificial eyelash. Further, since the natural eyelash and the artificial eyelash make surface-to-surface contact with each other, a bonding force by an adhesive and durability thereof are excellent. In addition, the artificial eyelash is lighter and softer and is more preferably dyed than a conventional one that has a circular or oval cross section.

Description

False eyelashes

The present invention relates to false eyelashes, and more particularly, to a false eyelash in which the cross section of the false eyelash strand has a rectangular shape and at least one pair of concave sides facing each other in the rectangular shape has a concave shape.

The false eyelashes have disposable accelerator eyelashes and extension eyelashes. Disposable acceleration eyebrows have a form in which a plurality of acceleration eyelash strands 12 are attached to the band 11 as shown in FIG. 1A, and the plurality of acceleration eyelash strands 12 are connected through one band 11. Although it is convenient to be able to obtain the effect of lumping together, but it is literally disposable, there is a fundamental inconvenience in that the band 11 is attached to and removed from the eyelids each time using an adhesive.

Republic of Korea Patent No. 1392845 (2014.05.09.) Has been disclosed a technique for stably connecting the eyelash strand 12 in the band 11 without falling off, Republic of Korea Patent No. 1,36,422 (2013.12.04. In the announcement), a technique for increasing the eyelash dimension by accelerating the eyelash strands 12 in one band 11 has various curls has been disclosed. Do not overcome the inconvenience of disposable.

In recent years, as shown in FIG. 1B, the eyelashes for extension can be used for a long time by adhering the eyelash strands 22 for one-to-one to the natural eyelashes in person one by one.

Republic of Korea Patent No. 915027 (2009.09.02.) Has been disclosed a technique for obtaining the effect of minimizing the shape change and removing foreign substances by allowing the eyelash strand 22 for extension to cross-link, Republic of Korea Patent No. 150341 (2004.10) [20.] has been disclosed a technique for using the bridge adhesive structure to securely attach the extension eyelash strand 22 for a long time. However, these techniques are not directly related to the shape of the cross section for improving the adhesion of the extension eyelash strand 22, and the like.

Republic of Korea Patent No.1396272 (2014.05.19.) Has been disclosed in the case where the cross-section of the extension eyelash strand 22 is elliptical, in the paragraph of this document 'adhesive portion is flat with respect to the oval. Therefore, since the surface area is wider than the round surface of the existing circular yarn, and the adhesion area is increased, the retention time (adhesion time) after adhesion to the natural eyelashes is significantly longer. '

However, even when the cross section is elliptical in shape, both the natural eyelashes and the extension eyelash strands 22 are convex, so it is difficult to precisely match them. The problem is that there are many cases.

2 is a view for explaining a conventional extension eyelash strand 22, which shows a case where the cross section of the extension eyelash strand 22 is circular. As shown in FIG. 2, when the cross-section of the extension eyelash strand 22 is circular, since the natural eyelash strand 1 and the extension eyelash strand 22 make point contact, the contact area is small and thus the adhesive 30 is applied. There is a disadvantage that the adhesion by weak.

Figure 3 is a view for explaining a conventional extension eyelash strand 22, showing a case in which the extension eyelash strand 22 has an elliptical shape as disclosed in Patent No. 13,627,021 (2014.05.19. Notification). will be. In the case of an oval, the contact area by the adhesive 30 may be wider than that of the circular shape, and thus stronger adhesion may be achieved. However, since the contact part is basically convex, the disadvantage of point contact cannot be overcome. .

On the other hand, the weight reduction of the extension eyelash strands 22 is also a significant problem, in the conventional case has not been considered at all about the weight reduction of the extension eyelash strands 22.

Therefore, the problem to be solved by the present invention, the artificial eyelashes that can solve the above-mentioned problems by being lighter than the case of the conventional circular or oval, as well as stable and reliable adhesion is made in virtually in contact with the natural eyelash strands. To provide.

The artificial eyelashes according to the present invention for achieving the above object is characterized in that the cross section of the artificial eyelash strands have a square shape but at least a pair of concave sides facing each other.

In this case, the upper and lower sides of the quadrangle have a concave shape, and the left and right widths of the quadrangle are w1, the thickness of the top and bottom are t1, and the thinnest up and down thickness of the portion concave by the top and bottom sides is t2, 0.4. It is preferable to have a relationship of x t1 < t2 < 0.8 x t1 and t1 < w1 < 1.5 x t1.

The left and right sides of the quadrangle may have a concave shape to the left and right, and in this case, when the narrowest left and right widths of the portions having the concave shape by the left and right sides are w2, 0.4 x w1 <w2 <0.8 x w1 It is desirable to have a relationship.

One end of the false eyelash strand is tapered (tapering) is preferably thinner and thinner and separated from side to side toward the end.

According to the present invention, since the natural eyelash strand is naturally guided to the center of the concave portion of the false eyelash strand, the natural eyelash strand can always be reliably attached to a certain position of the false eyelash strand. In addition, since the natural eyelash strands and the artificial eyelash strands are interviewed with each other, the adhesion by the adhesive and its durability are excellent. In addition, it is lighter and softer than the conventional case of round or oval and is more advantageous for dyeing.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. The following examples are only presented to understand the content of the present invention, and those skilled in the art will be capable of many modifications within the technical spirit of the present invention. Therefore, the scope of the present invention should not be construed as limited to these embodiments.

4 is a view for explaining the false eyelashes according to an embodiment of the present invention, Figure 4a is a perspective view, Figure 4b is a cross-sectional view taken along the line AA 'of Figure 4a.

As shown in Figure 4, the false eyelashes according to an embodiment of the present invention is a cross-section of the false eyelash strand 122 has a rectangular shape, the upper side and the lower side is recessed in a round concave shape.

It is preferable to have a relationship of 0.4 x t1 <t2 <0.8 x t1 when the left and right widths of the rectangular shape are w1, the top and bottom thickness is t1, and the thinnest up and down thickness of the part having a concave shape by the top and bottom sides is t2. Do. If the thickness of the concave portion (t2) is too thin, the false eyelash strand 122 becomes a problem because it is easy to break, and if it is too thick, it means that the radius of curvature is large and the depression is less. It is difficult to obtain a contact effect.

In this case, it is particularly desirable to have a relationship of t1 ≦ w1 ≦ 1.5 × t1. Since the concave portion will be glued to the natural eyelash strand, it is difficult to roll up the false eyelash strand 122 if the thickness t1 covers more than the left and right width w1 when the false eyelash strand 122 is concave up and down. If the left and right width w1 is larger than the thickness t1 is slightly flat overall, it is preferable because the adhesive surface with the natural eyelash strands is wider, but if too flat, the thickness t2 of the middle part is too thin, which is not preferable because it is too thin. Therefore, it is preferable that the left and right width w1 and the up and down thickness t1 satisfy the above conditions.

One end portion of the false eyelash strand 122 is tapered so that the upper and lower thicknesses t1 and t2 become thinner and closer to the ends so as to be separated from side to side. The opposite side of the tapered portion 122a will be glued to the natural eyelash strand and the tapered portion 122a will be the outer end of the eyebrow.

The tapered portion 122a has a branch that is divided into two branches as the top and bottom become thinner toward the end, so that the tapered portion can be rolled up nicely when being trimmed and also the effect of the eyelashes appearing more visible. Can be. It also has a very soft touch.

5 is a view for explaining the false eyelashes according to another embodiment of the present invention, Figure 5a is a perspective view, Figure 5b is a cross-sectional view along the line AA 'of Figure 5a.

As shown in FIG. 5, according to another example of the present invention, not only the upper and lower sides of the cross section are concave, but also the left and right sides are concave together. This has the advantage that all four sides of the false eyelash strand 122 can be utilized as an adhesive surface. At this time, when the narrowest left and right widths of the portions concave by the left side and the right side are w2, it is preferable to have a relationship of 0.4 x w1 <w2 <0.8 x w1.

As described above, the present invention is characterized in that the cross section of the false eyelash strand 122 has a quadrangular shape, but at least a pair of concave sides facing each other have a concave shape as follows.

6 is a view for explaining the adhesion of the false eyelash strand 122 and the natural eyelash strand 1 according to the present invention.

As shown in FIG. 6, according to the present invention, the natural eyelash strand 1 is naturally guided to the center of the concave portion of the false eyelash strand 122 so that the natural eyelash strand 1 always remains of the false eyelash strand 122. It is reliably attached to a certain position. In addition, since the natural eyelash strand 1 and the artificial eyelash strand 122 are interviewed with each other, the adhesive force by the adhesive 30 is further improved.

Extension false eyelashes are connected 1: 1 to a person's real eyelashes to create a natural and beautiful eyelash, which is very important because it has to last two to three weeks after a procedure. In particular, when washing the face in the conventional case, the false eyelashes tend to fall frequently, according to the present invention solves this problem.

Furthermore, assuming that the cross section is circular or elliptical in the prior art, the eyelash strands 122 may have a smaller cross sectional area than the prior art. Light weight is preferable. In addition, since the side wall of the false eyelash strand 122 is recessed along the longitudinal direction, there is an advantage that the false eyelash strand 122 is more flexible and softer than the conventional one having a circular or oval cross section in geometric structure.

Meanwhile, the artificial eyelash strand 122 according to the present invention, after spinning the polymer through an extruder (melt spinning), wet cooling (wet cooling), emulsion adsorption (adsorption of Obtained through known processes such as oil, drawing, heat setting, anti-static procedure, winding, tow bundle and tapering.

At this time, the nozzle of the extruder used in the melt spinning process (nozzle) is used in the shape of a square rather than circular, a pair of concave sides as shown in Figure 4b, or all four sides concave as shown in Figure 5b By using the false eyelashes of the present invention can be obtained.

And when we want to dye the filament into the bundle during the above process, the voids between the yarns are larger than the conventional round yarns, so more space for dye penetration can be expected. have.

7 is an actual micrograph of the false eyelash according to the present invention, Figure 7a is one end of the false eyelash strand 122, Figure 7b is a tapered portion 122a as the other end, Figure 7c is a cross section.

FIG. 8 is an actual micrograph of a conventional extension false eyelash having a circular cross section, FIG. 8A is one end of the extension false eyelash strand 22, and FIG. 8B is a tapered portion as the other end. 22a, and FIG. 8c is a cross section. If the extension false eyelash strand 22 as shown in Figure 8 has a rounded shape, the tapered end portion 22a has a sharp point in the middle as shown in Figure 8b, the thickness of the upper and lower as in the present invention It is difficult to obtain a form in which the ends are separated from side to side while being made.

As described above, according to the present invention, since the natural eyelash strand 1 is naturally guided to the center of the concave portion of the false eyelash strand 122, the natural eyelash strand 1 is always a constant position of the false eyelash strand 122. Can be reliably attached. In addition, since the natural eyelash strand 1 and the artificial eyelash strand 122 are interviewed with each other, the adhesion by the adhesive 30 and its durability are excellent. In addition, it is lighter and softer than the conventional case of round or oval and is more advantageous for dyeing.
