Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of magnetic strips, in particular to an injection-molded micro magnetic strip and a magnetic false hair decorative piece. Background Art
[0002] False eyelashes are artificial eyelashes used to beautify the eyes. Generally, the eyelashes are lengthened and thickened to make the eyes look bigger, brighter, fuller and more lively. In the prior art, magnetic false eyelashes that can be worn by magnetic force include two false eyelashes that can be adsorbed and connected. When used, the two false eyelashes clamp the real eyelashes of the human eye to achieve the wearing of false eyelashes. Generally, the roots of false eyelashes are glued and fixed on a sheet-like magnetic strip, and the surface of the sheet-like magnetic strip is flat. Since there are many nodules and hair heads at the roots of false eyelashes, after the roots of false eyelashes are fixed on the flat sheet-like magnetic strip, it is easy to rub the eyelids when worn for a long time, and the eyelids have a strong foreign body sensation, and the comfort of human use is poor.

[0034] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0038] Please refer to Figure 1-7 , which shows an injection molded micro magnetic strip 1 of the utility model. Specifically, the injection molded micro magnetic strip 1 includes a magnetic horizontal strip 11 and a magnetic vertical strip 12; the magnetic vertical strip 12 is arranged on the magnetic horizontal strip 11 along the length direction of the magnetic horizontal strip 11 to form a carrier for carrying and positioning the false hair 2, and the cross-sectional shape of the injection molded micro magnetic strip 1 along the height direction has an L-shaped area or a quasi-L-shaped area, and the root 21 of the false hair 2 is positioned on this L-shaped area or the quasi-L-shaped area when used. Wherein, the injection molded micro magnetic strip is integrally injection molded.
[0039] The injection molded micro magnetic strip 1 serves as a carrier, i.e., a hair stem, for false hair 2 such as false eyelashes or false eyebrows, wherein the carrier 13 is used to fix the root 21 of the false hair 2. The above-mentioned false hair 2 can be a single false eyelash, or a cluster of false eyelashes, or a single false eyebrow, or a cluster of false eyebrows. The false hair 2 can be made of synthetic fibers such as polyester or PBT, or natural fibers such as silk or mink. The length, curvature, color and / or thickness of the fibers can be the same or different to provide different makeup results, such as false eyelashes can make the eyes wider, open the eyes, increase the density of eyelashes, lengthen eyelashes or color eyelashes, and false eyebrows can provide color effects on certain areas of the natural edge or increase the density of human eyelashes in specific areas. Figure 8As shown, the roots 21 of several false hairs 2 can be pasted on the carrier 13, or fixed on the carrier 13 by welding, or fixed on the carrier 13 by hot pressing, or fixed on the carrier 13 by magnetic adsorption. The carrier 13 has a table 131 and a side wall 132. The table 131 and the side wall 132 are connected to form an L-shaped area or a quasi-L-shaped area, and the roots 21 of the false eyelashes are fixed on the L-shaped area or the quasi-L-shaped area. It can be understood that the table 131 can be a horizontal plane or an inclined plane; the side wall 132 can be a vertical plane or an inclined plane. The side wall 132 can be a vertical magnetic strip 12 or a part of the vertical magnetic strip 12. Preferably, the bottom surface of the root 21 of the false hair 2 abuts against the side wall 132 of the carrier 13 and the side surface of the root 21 is fixed on the table 131 of the carrier 13, so that the carrier 13 not only carries the false hair 2, but also is used to position the false hair 2, so as to facilitate the rapid fixing of the false hair 2. Since the root 21 of the false hair 2 is not higher than the top of the side wall 132, the nodules and hair heads of the root 21 of the false hair 2 can be avoided from directly contacting the eyelids, thereby protecting the eyes.
[0040] The "micro" in the injection molded micro magnetic stripe 1 can be understood as light and thin. The total length L of the injection molded micro magnetic stripe 1 is 4~28mm, the total width W is 1.0~2.0mm, and the total height H is 0.3~0.8mm; the width w1 of the table 131 of the carrier 13 is 0.5~1.0mm, the width w2 of the non-table side of the carrier 13 is 0.5~1.0mm, and the height h of the side wall 132 of the carrier 13 is 0.2~0.6mm. It should be noted that the above dimensions can be adjusted according to actual needs, such as Figure 5-7 shown.
[0041] The existing ones are generally made of rubber materials, magnetic powder (magnetic filler) and other additives, and are cut by extrusion and punching. Because a lot of magnetic chemicals are added to the rubber, the properties of the rubber are greatly reduced, the compressive strength is small, and it cannot be used as a load-bearing component, making the magnetism much smaller than that of a real magnet. In addition, it is easy to cause obvious deformation due to thermal expansion and contraction caused by temperature. In order to solve this problem, the injection-molded micro magnetic strip 1 of the utility model is an integral injection-molded body obtained by injection molding the injection-molded magnetic material. The weight of the injection-molded micro magnetic strip 1 can be controlled at 0.01~0.15g, and the injection-molded magnetic material is used for one-time injection molding production, and the finished magnetic strip 1 is produced at one time, which can be directly used as a fake hair stem, without pressing or cutting, and without secondary arrangement and bonding, and the process is simplified. The process flow is simple, and a large number of injection-molded products can be processed at the same time, the speed is fast, and no secondary processing is required. Since the injection-molded magnetic strip 1 is consistent with the injection mold cavity in size, the dimensional accuracy can be controlled to be relatively high. In this way, the injection-molded micro magnetic strip 1 is obtained based on the one-time injection molding of the injection-molded magnet, which is not only thin and light, but also has good flexibility and comfort to wear, and at the same time satisfies the magnetic adsorption performance, and is easy to wear and remove. The injection-molded micro magnetic strip 1 of the utility model is thin and light, can be deformed with the movement of the eyelids, can be well adapted to the eyes, so that the user will not have any foreign body sensation or discomfort.
[0042] The injection molded micro magnetic strip 1 is provided with several pairs of magnetic poles (not shown in the figure) along its length direction, and has a reliable connection at multiple points when in use. The bottom of the injection molded micro magnetic strip is flat, the purpose is to make the upper and lower magnetic strips fit fully. A pair of magnetic poles includes N level and S level, and the N level and S level in the magnetic strip are arranged at intervals. Regarding the magnetic field orientation, both isotropic magnetic strips and anisotropic magnetic strips can be produced during injection molding. For isotropic magnetic powder, multiple pairs of magnetic poles can be obtained by magnetizing after injection molding, and for anisotropic magnetic powder, multiple pairs of magnetic poles can be directly obtained by in-mold orientation magnetizing process. It can be understood that when two injection molded micro magnetic strips 1 are magnetically attracted to each other and used together, the magnetic poles of the two injection molded micro magnetic strips 1 are arranged oppositely, so that the two injection molded micro magnetic strips 1 are attracted to each other with different magnetic poles when connected. When in use, two injection molded micro magnetic strips 1 can be connected to the upper and lower sides of the real eyelashes 3 of the upper eyelid of the human eye by magnetic attraction using a special eyelash curler or manually, to obtain a magnetic false eyelash decoration.
[0043] The injection molded micro magnetic strip 1 is an arc-shaped structure or a linear structure, and can also be other shapes, such as adapting to the curved shape of eyelids, etc. The corresponding injection mold can be designed according to actual needs.
[0044] Please refer to Figure 1-7, the contour edge of the carrier 13 is set to an arc-shaped transition surface 133. Such a design can avoid the right-angle edge from scratching the eyelids, thereby improving the safety of use. Furthermore, the two ends of the injection-molded micro-magnetic strip 1 in the length direction are also rounded to form arc ends 14. Preferably, the side edges of the vertical magnetic strip 12 are rounded to form an arc-shaped slope 15. With such a structural design, the contour edges of the injection-molded micro-magnetic strip 1 have a certain curvature, making it round as a whole without sharp right-angle edges, avoiding scratching the eyelids and increasing safety. It should be noted that the curvature of the above-mentioned arc-shaped transition surface, arc end, and arc-shaped slope can be adjusted according to actual needs.
[0045] Please refer to 8, which shows a magnetic false hair decoration of the utility model, which includes the above-mentioned injection molded micro magnetic strip 1 and a plurality of false hairs 2 fixed on the carrier 13 of the injection molded micro magnetic strip 1. The false hair 2 can be a single false eyelash, a cluster of false eyelashes, a single false eyebrow, or a cluster of false eyebrows.
[0046] When used specifically, taking false eyelashes as an example, a pair of injection-molded micro magnetic strips 1 with different magnetic pole directions, one of which is used as an upper magnetic strip, and a plurality of false eyelashes are fixed on its carrier 13, and the eyelashes are bent and extended toward one side of the carrier 13; the other is used as a lower magnetic strip, and a plurality of false eyelashes are fixed on its carrier 13, and the eyelashes are bent and extended toward the plane side; a special eyelash curler or manual can be used to connect the upper and lower magnetic strips to the upper and lower sides of the real eyelashes 3 of the upper eyelid of the human eye through magnetic attraction to obtain a false eyelash decoration, such as Fig. 9 In another embodiment, the lower magnetic strip is a flat magnetic sheet 4, which does not fix the false eyelashes, but only attracts the upper magnetic strip. Fig.10 When disassembling, the two injection-molded micro magnetic strips 1 can be removed by gently moving them apart, so wearing and disassembling are convenient and quick. Because of the magnetic connection, wearing and disassembling will not cause any damage to the eyelash decoration, so it can be used repeatedly.
