Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, specifically to a thick eyelash strand, eyelash cluster, and eyelash segment. Background Technology

[0002] Human eyelashes grow on the anterior lip of the eyelid margin, arranged in 2-3 rows, short and curved. Upper eyelid eyelashes are more numerous and longer, typically numbering 100-150, with an average length of 8-12 mm, and grow slightly forward and upward. The inclination of the upper eyelid hairs is generally 110-130 degrees in 79.8% of men when looking straight ahead with eyes open, and 140-160 degrees in 83.5% when eyes closed. The inclination is roughly the same in women as in men. Eyelashes also serve a protective function.

[0003] False eyelashes are artificial products used to beautify the eyes, often used to lengthen or increase the density of natural eyelashes for decorative purposes. Current technology, to improve the density of false eyelashes, often involves increasing the grafting density of the false eyelash strands or clusters, or increasing the density of the lash strands within the false eyelash segments to make the strands finer. This not only increases the difficulty and workload of grafting but also raises the manufacturing complexity of the false eyelashes themselves, resulting in poor economic returns. Utility Model Content

[0004] This utility model discloses a dense eyelash strand, eyelash cluster, and eyelash segment, which solves the technical problems of insufficient density or difficult processing of existing false eyelashes. It achieves the technical effects of reasonable structure, good density, and excellent decorative effect. The technical solution adopted is as follows:

[0005] A dense eyelash filament includes an eyelash filament body, the eyelash filament body including a root, the root extending outward to form an extension portion, the extension portion including multiple length segments, and at least one of the length segments having a plurality of tufts adhered to it. The root of the dense eyelash filament is used for adhesion to human eyelashes. Preferably, the tufts are made of nylon, polyester, or viscose fiber. Preferably, the tufts are adhered to the eyelash filament body using a flocking method.

[0006] Based on the above technical solution, some of the filaments are different in color and / or in length.

[0007] Based on the above technical solution, several filaments with different densities are arranged along the axial direction of the length segment.

[0008] Based on the above technical solution, a length segment with several filaments bonded together is arranged near the end of the extension.

[0009] Based on the above technical solution, the root tapers outwards to facilitate adhesion to human eyelashes. Preferably, the cross-section of the eyelash body is approximately circular or flat. When the cross-section of the eyelash body is approximately circular, the projection of the root on the horizontal plane is trapezoidal, triangular, or semi-elliptical, with the top larger than the bottom. When the cross-section of the eyelash body is approximately flat, the projection of the root on the horizontal plane is approximately trapezoidal, triangular, semi-elliptical, or other irregular shapes, with the top larger than the bottom.

[0010] A thick eyelash cluster includes multiple eyelash filament bodies as described above, the roots of which are connected to form a root plate. The root plate of the thick eyelash cluster is used for adhesion to human eyelashes.

[0011] Based on the above technical solution, the cross-section of the eyelash body is flat, and multiple eyelash bodies are integrally cut and formed on a flat sheet material. In this way, multiple eyelash bodies share a single sheet, which is convenient for processing and avoids the problem of weak bonding after the root sheet is too thick.

[0012] Based on the above technical solution, at least two eyelashes have different lengths, curvatures, or orientations.

[0013] A thick eyelash segment includes a band body and several eyelash filaments as described above, the roots of which are connected to the band body and arranged along its length. Preferably, at least two eyelash filaments are of different lengths, curvatures, or orientations to form various arrangements. The band body is used to adhere to human eyelashes. Preferably, the length of the band body is less than or matched to the length of human eyeliner.

[0014] Based on the above technical solution, the strut body and the eyelash body are flat, and the strut body and several eyelash bodies are integrally cut on a flat sheet material.

[0015] Beneficial effects

[0016] This invention features a rationally designed structure. In the dense eyelash extensions, at least one length of the extension portion is bonded with several fine and soft filaments. These filaments not only significantly enhance the density of the eyelashes but also provide excellent flexibility and a superior decorative effect after application. The filaments can be attached to the eyelash extensions using a flocking method, resulting in high processing efficiency and good density. Furthermore, the filaments can be extended to different lengths and / or variations, further increasing versatility and better meeting user needs. The dense eyelashes taper from the root outwards, ensuring a smooth transition at the point of contact between the root or root piece and the natural eyelash after grafting. This avoids abrupt changes in cross-section and the formation of a stepped structure, greatly improving the user experience and extending the durability of the eyelash extensions.

[0017] The dense eyelash cluster of this invention includes multiple eyelash filament bodies, and the roots of the multiple eyelash filament bodies are connected to form a root sheet. Specifically, the multiple eyelash filament bodies in the dense eyelash cluster can be integrally cut on a flat sheet material, which makes the structure lightweight and easy to process.

[0018] In this embodiment, the dense eyelash segment includes a strut body and several eyelash filament bodies. The strut body and several eyelash filament bodies can be integrally cut into a flat sheet material, which is convenient for processing and shaping. Attached Figure Description

[0036] Example 1

[0037] like Figures 1-3 The illustrated thick eyelash 10 includes an eyelash body 1, which includes a root 11. The root 11 extends outward to form an extension 12, which includes multiple length segments, and at least one of the length segments has several fine hairs 13 attached to it. Figure 1 As shown, the extension 12 is divided into upper and lower length segments, and several filaments 13 are glued to the length segment away from the root 11. Among them, the root 11 of the dense eyelash filaments 1 is used to attach to the human eyelashes.

[0038] In this embodiment, the filaments 13 are made of nylon, polyester, or viscose fiber, and the length segments to which several filaments are bonded are arranged near the end of the extension portion 12. In this embodiment, the several filaments 13 are bonded to the eyelash body 1 using a flocking method. The flocking method is existing technology and, as an example, includes the following steps:

[0039] S1. First, apply adhesive to the length of the eyelash body 1 to which the velvet 13 is to be bonded. The adhesive is existing technology, such as polyurethane adhesive.

[0040] S2. The eyelash body 1, which is evenly coated with adhesive on the length segment, is sent into the flocking chamber. In the flocking chamber, the flock 13 is charged to make it static electricity. Several flock 13 are vertically bonded to the length segment by using static electricity. The flock adhesion density and uniformity are controlled by adjusting the electric field strength and the flock delivery method.

[0041] S3. After flocking is completed, heat and cure the eyelash fiber body 1 to dry the adhesive and fix the flocking fibers.

[0042] In other embodiments of this utility model, a plurality of filaments 13 may also be bonded to the eyelash body 1 by other methods.

[0043] In this embodiment, the cross-section of the eyelash body 1 is approximately flat. The eyelash body 1 is integrally formed by laser cutting on a flat sheet material. In this embodiment, the flat sheet material is selected from plastics with a thickness of 0.02~0.4 mm, such as polyethylene, nylon, polyvinyl fluoride, polypropylene, etc., which are inexpensive and readily available. Laser cutting on plastic materials is an existing technology, such as using ultraviolet laser cutting machines or green laser cutting machines to cut thin plastic sheet materials. When using an ultraviolet laser cutting machine, its rated power is 6~12W, the laser width is 10~20µm, the processing accuracy is high, and it can be used for cutting and forming with high dimensional accuracy. In addition, the cut edges are smooth, which can eliminate the need for subsequent grinding and finishing processes, which is beneficial to improving product quality.

[0044] like Figure 4 The illustrated thick eyelash cluster 20 includes multiple eyelash filament bodies 1 as described above, with the roots 11 of the multiple eyelash filament bodies 1 connected as a single unit to form a root plate 2. The root plate 2 of the thick eyelash cluster 20 is used for bonding to human eyelashes. The cross-sections of the multiple eyelash filament bodies 1 in the thick eyelash cluster 20 are all flat, and the multiple eyelash filament bodies 1 are integrally cut from a flat sheet material. This allows multiple eyelash filament bodies 1 to share a single sheet 2, facilitating processing and avoiding weak bonding due to the thickness of the root plate. At least two eyelash filament bodies 1 may have different lengths, curvatures, or orientations to create a variety of arrangement patterns.

[0045] In other embodiments of this utility model, in the multiple eyelash bodies 1 of the dense eyelash cluster 20, several filaments 13 may be arranged at different positions on the eyelash body 1.

[0046] like Figure 5 The illustrated thick eyelash segment 30 includes a strut body 3 and several eyelash filament bodies 1 as described above. The roots 11 of the eyelash filament bodies 1 are connected to the strut body 3 and arranged along the length of the strut body 3. The strut body 3 is used to adhere to human eyelashes. In this embodiment, the length of the strut body 3 is less than the length of human eyeliner, so that thick eyelash segments can be adhered in segments as needed.

[0047] Furthermore, the strut body 3 and the eyelash filament body 1 are flat, and the strut body 3 and several eyelash filament bodies 1 are integrally cut from a flat sheet material. Similarly, at least two eyelash filament bodies 1 are of different lengths, curvatures, or orientations to form a variety of arrangement patterns.

[0048] Example 2

[0049] The difference between Example 2 and Example 1 is as follows:

[0050] Thick eyelashes, out of 10 types, have some strands of different colors and / or varying lengths, such as... Figure 6As shown;

[0051] In the 20 dense eyelash clusters, the arrangement of several fine hairs on multiple eyelash bodies 1 is different;

[0052] In the dense eyelash segment 30, on multiple eyelash strands 1, the length of the stem body 3 matches the length of the human eyeliner, and the stem body 3 extends along an arc, such as... Figure 7 As shown.

[0053] Example 3

[0054] The difference between Example 3 and Example 1 is as follows:

[0055] like Figure 8 As shown, in the thick eyelashes 10, the root 11 gradually tapers outwards; the root 11 is larger at the top and smaller at the bottom in the projection on the horizontal plane, roughly in the shape of a trapezoid, triangle, semi-ellipse or other irregular shape.

[0056] like Figure 9 and 10 In the dense lash clusters 20 shown, the root piece 2 tapers outwards, and the projection of the root piece 20 onto the horizontal plane is roughly trapezoidal, triangular, semi-elliptical, or other irregular shapes, with the larger portion at the top and the smaller portion at the bottom. This ensures a relatively smooth transition at the junction of the root 11 or root piece 2 and the human eyelash after grafting, avoiding abrupt changes in cross-section or the formation of a step-like structure, greatly improving the user experience and extending the durability of the eyelash extensions.

[0057] Example 4

[0058] The difference between Example 4 and Example 1 is as follows:

[0059] like Figure 11 As shown, in the thick eyelashes 10, the cross-section of the eyelash body 1 is roughly circular and not laser-cut. The projection of its root 11 on the horizontal plane is larger at the top and smaller at the bottom, forming a trapezoid, triangle, or semi-ellipse.

[0060] In the dense eyelash cluster 20, the roots of multiple eyelash strands 1 are bonded together with adhesive to form a root piece 2.

[0061] In the dense eyelash segment 30, the roots 11 of several eyelash strands 1 are glued to the stem strand 3 by adhesive.

[0062] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
