Description

  The present invention relates to an eyelash for extension, and more particularly, to an eyelash for extension having a rough surface.

  False eyelashes are one of the items that give the eyelashes length and volume to create a larger, beautiful and attractive eye. False eyelashes can give a length and volume to the user's eyelashes by putting together a plurality of artificial eyelashes, providing an adhesive part at the end thereof, and attaching the adhesive part to the user's eyelid (for example, Patent Documents 1 and 2). False eyelashes adhere to the user's skin, so the wearing feeling is poor, and in some cases the skin may be rashed.

  On the other hand, in recent years, artificial eyelashes called so-called extensions having a shape almost the same as a single eyelash and having a volume in length and thickness have been proposed (for example, Patent Document 3). This extension (artificial eyelashes) does not adhere to the eyelids but directly adheres to the eyelashes using an adhesive, so that the feeling of wearing is good and there is little risk of skin irritation. In addition, since the extensions are bonded one by one to each eyelash, the length and volume can be given to the eyelash more naturally than the false eyelashes.

  The extension disclosed in Patent Document 3 has a recessed portion that covers 1/4 or more of the user's eyelashes. The extension can be adhered to the eyelash while applying an adhesive to the extension having the indented portion and bringing the user's eyelash into close contact with the indented portion of the extension. By bringing the eyelashes into close contact with the indented portion, the adhesion area between the extension and the eyelashes can be increased, and as a result, it is easy to prevent the extension from peeling off or shifting.

  However, it is a difficult task to accurately fit the recessed portion of the extension from below into each eyelash. That is, when an extension without a concave portion (ordinary extension) is bonded to the eyelashes, the extension and the eyelashes may be bonded to each other via an adhesive, but in the case of the extension disclosed in Patent Document 3 It is necessary to match each eyelash to the inner surface of the recessed portion of the extension. Since the extension having the recessed portion is operated by pinching with tweezers, it takes time and effort to make the recessed portion face upward each time.

  On the other hand, in the case of an extension having no indented portion, the surface of the extension is formed smoothly, so that it cannot be said that the adhesive is always attached. That is, since the extension is manufactured by extruding a resin from a mold having an opening having a circular cross section, the surface of the manufactured extension is likely to be smooth, and therefore, the adhesive is excellently attached. hard. However, the extension with a smooth surface is standard, and the fact that the adhesive of the extension is poor has not yet been regarded as a problem in the industry.

  This invention is made | formed in view of this point, The main objective is to provide the eyelashes for an extension with good adhesion of an adhesive agent.

  An eyelash for an extension according to the present invention is an eyelash for an extension that extends the length of an eyelash, and includes an artificial eyelash main body, and the artificial eyelash main body includes a root portion that contacts the eyelash, and the root portion. Has a tip portion located on the opposite side, and the root portion has a rough surface portion.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, components having substantially the same function are denoted by the same reference numerals for the sake of brevity. In addition, this invention is not limited to the following embodiment.

  An extension eyelash 100 according to an embodiment of the present invention will be described with reference to FIG. FIG. 1 is a diagram showing a state in which the extension eyelash 100 of the present embodiment is attached to a user's (wearer) eyelash 50.

  The eyelash 100 for extension of this embodiment is an artificial eyelash that extends the length of the eyelash 50 of the user 55. In the present embodiment, the extension eyelashes are referred to as “extensions”.

  The extension 100 of this embodiment is composed of an artificial eyelash main body 10. The artificial eyelash body 10 of the present embodiment includes a root portion 15 that is in contact with the eyelash 50 and a tip portion 11 that is located on the opposite side of the root portion 15. In the configuration of the present embodiment, the root portion 15 has a rough surface portion 30.

  In the extension 100 of this embodiment, an adhesive (glue) 20 is attached to the root portion 15. Then, the extension 100 is bonded and fixed to the eyelash 50 by the adhesive 20. Specifically, the adhesive 20 is attached to the rough surface portion 30 in the root portion 15, and the extension 100 (or the artificial eyelash body portion 10) is attached to the eyelash 50 via the adhesive 20.

  FIG. 2 is a perspective view showing the configuration of the extension 100 of the present embodiment. FIG. 3 shows a cross-sectional view along the line AA in FIG. FIG. 4 shows an enlarged side view of a portion B in FIG.

  In the extension 100 of the present embodiment, the rough surface portion 30 is formed closer to the end surface 15 a side of the root portion 15 than the intermediate point in the longitudinal direction of the artificial eyelash main body portion 10. In particular, the rough surface portion 30 only needs to be formed in a region in contact with the eyelashes 50, and can be selectively formed only in a portion where the adhesive 20 is applied.

  The rough surface portion 30 of the present embodiment includes a plurality of granular irregularities 31. The rough surface portion 30 composed of the granular irregularities 31 is formed over the entire circumference of the root portion 15. Accordingly, a rough surface portion 30 is formed in all directions of the surface of the root portion 15, and the adhesive 20 is applied to the rough surface portion 30 even if it is applied to the root portion 15 from any direction. be able to.

  The artificial eyelash body 10 of the present embodiment has a shape in which the root 15 is thick and the tip 11 is thin. The artificial eyelash body 10 of the present embodiment is made of, for example, resin (typically polybutylene terephthalate, polyester, acrylic, vinyl chloride, nylon), and the length of the artificial eyelash body 10 is For example, the diameter φ (or thickness) is, for example, 0.07 mm to 0.3 mm.

  The artificial eyelash body 10 may be made of a colored material in addition to black. The artificial eyelash body 10 can be made into, for example, dark brown, purple, blue, pink, silver, green, light orange, light gold, red, wine red, white, yellow, etc. Can be realized. Moreover, although it is called the artificial eyelash body 10, it means that the length of the eyelashes is artificially extended. Therefore, the constituent material is not limited to an artificial material (resin etc.), but a natural material (for example, an animal) It is also possible to use derived materials (typically human hair, animal hair (mink or other hair) or silk), plant-derived material (typically cotton)).

  In the configuration of the present embodiment, the rough surface portion 30 of the artificial eyelash main body portion 10 is formed by performing frost processing. In other words, the artificial eyelash body 10 is provided with the irregularities 31 generated by frosting. Frost processing refers to processing that makes the surface gritty like frost (or processing that makes the surface gritty like frosted glass). In this embodiment, the irregularities 31 are formed on the artificial eyelash body 10 by sandblasting. Sand blasting is a processing method in which an abrasive such as sand is sprayed on the surface. For example, a rough surface portion 30 can be formed on the root portion 15 by spraying the root portion 15 of the artificial eyelash main body portion 10 with the abrasive mixed with the compressed air from the compressor. The sand (abrasive) used for sandblasting is not limited to so-called sand, and an abrasive suitable for forming the irregularities 31 on the artificial eyelash body 10 can be used.

  The depth of the unevenness 31 of this embodiment (the difference in height from the convex portion to the concave portion) is, for example, about 0.01 mm to 0.1 mm, but is not limited thereto. Specifically, it is determined by the conditions of the frost processing (for example, sand blasting) used to form the rough surface portion 30, and it is possible to appropriately form the irregularities 31 according to the frost processing to be used. It is.

  The rough surface portion 30 of the present embodiment can be formed by rubbing a file (specifically, a paper file). A paper file is a tool in which an abrasive is applied to a paper-like sheet used for polishing. When the rough surface portion 30 is formed by a paper file, the shape and depth of the unevenness 31 of the rough surface portion 30 can be adjusted by the roughness (count) of the paper file to be used.

  When the rough surface portion 30 is formed on the root portion 15 of the artificial eyelash main body portion 10, a large number of artificial eyelash main body portions 10 are aligned, and then sandblasting is applied to the root portion 15, so that the rough surface portion 30 is roughened. A number of artificial eyelash body portions 10 having the surface portion 30 can be formed. In addition, it is also possible to form a large number of artificial eyelash body parts 10 having a rough surface part 30 in a single process by applying a paper file to the root part 15 with a large number of artificial eyelash body parts 10 aligned. It is. Of course, the rough surface portion 30 may be formed by applying a paper file to the single artificial eyelash body 10.

  It is also possible to form a rough surface portion 30 by forming a through-hole in the artificial eyelash body 10 and using the through-hole. In that case, the length of the through-holes constituting the irregularities 31 corresponds to the diameter φ of the artificial eyelash body 10. When forming the through hole, an appropriate tool or the like for forming the through hole may be used. Further, when the through hole is formed, there is an advantage that the weight (mass) of the extension 100 can be reduced. Even if the weight of each extension 100 is light, they can be attached to the user's eyelashes, so reducing the weight of the extension affects the user's (wearer's) feeling of wearing. As a result, it is possible to realize an extension that feels comfortable to wear.

  Next, a method for attaching the extension 100 of the present embodiment to the eyelash 50 will be described with reference to FIGS.

  First, as shown in FIG. 5 (a), a part of the extension 100 of this embodiment is grasped by the tweezers 70, and the extension 100 is held near the eyelashes 50 with the adhesive 20 applied to the root portion 15. To go.

  Next, as shown in FIG. 5 (b), the adhesive 20 of the extension 100 is attached to the eyelash 50, and the extension 100 is brought into close contact with the eyelash 50. When the adhesive 20 is cured and the extension 100 is fixed to the eyelash 50, the tweezers 70 are removed as shown in FIG. 5C, and the attachment of the extension 100 is completed. This operation is performed for each eyelash 50.

  In the extension 100 of the present embodiment, since the root portion 15 of the artificial eyelash body 10 has the rough surface portion 30, the rough surface portion 30 makes it easy to hold the adhesive 20 and use it. The adhesion between the person's eyelashes 50 and the artificial eyelash body 10 can be improved. That is, since the surface of the conventional extension is formed smoothly, it cannot be said that the adhesive is always attached. However, in the case of the extension 100 of this embodiment, the rough surface portion 30 causes the surface in the case of smoothness. As a result, the surface area of the adhesive 20 is increased (or due to the unevenness 31), so that the adhesive 20 can be held well.

  Further, the holding force of the adhesive 20 is improved by the increased surface area of the rough surface portion 30. Accordingly, the area where the rough surface portion 30 is formed is preferably wider than the area where the adhesive 20 is applied, but the surface portion 30 adheres even if it is narrower than the area where the adhesive 20 is applied. It does not matter because the agent 20 can be held well.

  In recent years, due to the skin irritation or allergies of the user and the influence of other organic solvents, it is not possible to use strong adhesives, and it is necessary to use adhesives with relatively weak adhesive strength. Cases have also occurred. In such a case, in the conventional extension, the bad adhesion of the adhesive becomes more prominent, and there is a possibility that the extension mounting work may be hindered. On the other hand, in the extension 100 of this embodiment, since the adhesive 20 is attached well, such a problem can be suppressed even when an adhesive having a relatively weak adhesive force is used.

  Further, in the extension 100 of the present embodiment, the rough surface portion 30 is formed over the entire circumference of the artificial eyelash body portion 10, and therefore, the top surface of the rough surface portion 30 is not only from one direction but also from the other direction. The artificial eyelash body 10 can be adhered to the eyelash 50 by applying the adhesive 20 to the eyelash 50. Therefore, it becomes easier to attach the extension 100 to the eyelash 50 compared to an extension in which a C-shaped depression is formed in one direction.

  Further, the extension 100 of the present embodiment can be modified as follows. In the extension 100 shown in FIG. 6, the rough surface portion 30 is formed not only on the root portion 15 of the artificial eyelash body portion 10 but also on the entire artificial eyelash body portion 10. As shown in FIG. 6, even when the rough surface portion 30 is formed on the entire artificial eyelash body 10, the adhesive 20 is applied to the root portion 15 of the artificial eyelash body 10, and the artificial eyelash body 10. Can be attached to the eyelashes 50.

  The extension 100 of this embodiment as shown in FIGS. 1 and 2 can be manufactured as follows, for example. First, a resin is extruded from a mold having an opening having a circular cross section to produce a fibrous material having the same diameter φ. Next, the fibrous material is cut into the same length as the artificial eyelash body 10. Thereafter, a part of the artificial eyelash body 10 obtained by the cutting is immersed in a chemical, and the tip 11 of the artificial eyelash body 10 is thinned. Here, when the rough surface portion 30 is formed on the whole of the artificial eyelash main body 10 by frosting or the like, when the part (tip portion) of the artificial eyelash main body 10 is immersed in a chemical, The rough surface portion 30 in the portion may disappear. In that case, a rough surface portion 30 is formed on the root portion 15 (or the periphery thereof) of the artificial eyelash body portion 10.

  On the other hand, when the rough surface portion 30 is formed on the entire artificial eyelash body 10 by frosting or the like after the tip 11 of the artificial eyelash body 10 is thinned, an extension 100 as shown in FIG. 6 is obtained. be able to. Further, even after the tip 11 of the artificial eyelash body 10 is thinned, the tip 11 (or the portion excluding the root portion 15) of the artificial eyelash main body 10 is masked and subjected to frosting or the like. Thus, the rough surface portion 30 can be formed on the root portion 15 of the artificial eyelash body portion 10.

  The rough surface portion 30 may be formed on the end surface 15a of the root portion 15, or may not be formed. In the configuration of the present embodiment, as shown in FIG. 3, the rough surface portion 30 (unevenness 31) is formed over the entire circumference of the root portion 15, but a partially rough surface portion 30 (unevenness 31). A portion where no is formed may be provided. For example, the surface portion 30 (unevenness 31) that is rough in four directions (90 °) and eight directions (45 °) may be formed instead of the entire circumference of the root portion 15. Even if the surface portion 30 (unevenness 31) that is rough in four directions (90 ° each) and eight directions (45 ° each) is formed, the adhesive 20 is applied to the root portion 15 from multiple directions instead of one direction. It can apply | coat and the adhesion of the adhesive agent 20 can be improved.

  Furthermore, the extension 100 of the present embodiment can be modified as follows. In the extension 100 shown in FIG. 7, the uneven part 33 including a plurality of scratch-like grooves is formed in the root part 15 of the artificial eyelash body part 10. In other words, a rough surface portion 32 including irregularities 33 formed of scratch-like grooves is formed in the root portion 15 of the artificial eyelash body portion 10.

  The unevenness 33 composed of a plurality of scratch-like grooves can be formed, for example, by damaging the surface of the artificial eyelash body 10 using an instrument in which fine blades are arranged. Further, by devising a method of rubbing the paper file, it is possible to form the unevenness 33 composed of a plurality of scratch-like grooves. Specifically, the concave / convex 33 composed of a plurality of scratch-like grooves is formed by rubbing a paper file with the artificial eyelash body 10 so that fine grooves (short linear grooves) are not connected to each other. Can do.

  In addition, in the extension 100 shown in FIG. 7, the uneven portion 33 of the scratch-like groove (or scratch) is formed in the root portion 15 (or the periphery thereof). However, as shown in FIG. It is also possible to form the unevenness 33 on the surface.

  Also in the extension 100 shown in FIGS. 7 and 8, the rough surface portion 32 makes it easy to hold the adhesive 20, and improves the adhesiveness between the user's eyelash 50 and the artificial eyelash body 10. be able to. In addition, in the illustrated example, the rough surface portion 32 is formed over the entire circumference of the artificial eyelash main body portion 10, so that it is adhered to the rough surface portion 30 not only from one direction but also from the other direction. The artificial eyelash body 10 can be adhered to the eyelash 50 by applying the agent 20. Therefore, it becomes easier to attach the extension 100 to the eyelash 50 compared to an extension in which a C-shaped depression is formed in one direction.

  FIG. 8 shows a state in which the extension 100 is attached to each of the upper eyelashes 50. As shown in FIG. 8, extensions 100 are attached to many eyelashes 50. In the extension 100 of this embodiment, since the rough surface portion 30 (or 32) formed on the artificial eyelash body portion 10 is used, it becomes easy to attach the artificial eyelash body portion 10 to the eyelash 50. The extension 100 can be easily attached as compared with a conventional smooth surface extension.

  As mentioned above, although this invention was demonstrated by suitable embodiment, such description is not a limitation matter and of course various modifications are possible. For example, in the configuration shown in FIG. 8, the extension 100 may be attached to the lower eyelash. Furthermore, in the state shown in FIGS. 5A to 5C, not the adhesive 20 but a liquid (for example, water or a liquid having a viscosity higher than that of water (typically a liquid cosmetic). ) To temporarily fix the artificial eyelash body 10 to the eyelash 50. By this temporary fixing, the user (wearer) 55 can confirm the design and the comfort of the extension 100 of the present embodiment. In the case of the extension 100 according to the present embodiment, the liquid (water or liquid cosmetic) is held by the rough surface portion 30 (32) of the artificial eyelash body portion 10 due to the surface tension, so that it is temporarily fixed. There is also an advantage that work is easy to perform.

  Further, in the example shown in FIGS. 5A to 5C, the example in which the extension 100 of the present embodiment is attached to the eyelash 50 of the user (wearer) 55 is shown, but the eyelash 50 is an eyelash of false eyelashes. It may be a part. That is, by attaching the extension 100 of the present embodiment to the eyelash portion 50 of the false eyelash instead of the human eyelash, a unique false eyelash according to the user's preference can be produced. In addition, as an exercise for attaching the extension, the extension 100 may be attached to the eyelash portion 50 of the false eyelash. Even when the extension 100 is attached to the eyelash portion 50 of the false eyelashes, the extension 100 can be easily attached by using the rough surface portion 30 (32) in the present embodiment.

  ADVANTAGE OF THE INVENTION According to this invention, the eyelash for extensions (extension) with a sufficient adhesion of an adhesive agent can be provided.
