Description

Freely combinable eyelash extensions Technical Field

[0001] This utility model relates to the field of false eyelash technology, and in particular to a freely combinable eyelash extension material. Background Technology

[0002] Existing false eyelashes consist of several eyelash strands, which are joined together at the root to form an adhesive band. After applying false eyelash glue to the adhesive band, they are bonded to the individual's natural eyelashes. However, due to the differences in the shape and curvature of the human eye, as well as the variations in the length and density of eyelashes at different locations of the eye, existing single-piece false eyelashes not only fail to adapt to different individual eye contours but also cannot be freely combined to accommodate the varying lengths and densities of eyelashes at different locations of the eye. This results in poor realism and aesthetics when worn.

[0003] Therefore, a free-combination eyelash extension material is needed to solve the above problems. Utility Model Content

[0004] This invention proposes a freely combinable eyelash extension. By setting easy-tear lines on the adhesive strip, the strip can be manually torn along any easy-tear line without the aid of tools. This allows the freely combinable eyelash extension to be worn as a whole or disassembled into at least one cluster for individual wear. When wearing it, different types of eyelash clusters can be freely combined according to the length and density of individual eyelashes, making the false eyelashes closer to natural eyelashes and improving the realism and aesthetics of the worn eyelashes.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A freely combinable eyelash extension includes multiple strip films and multiple sets of eyelash clusters. Each eyelash cluster includes multiple layers of eyelash fibers. Each strip film has at least one adhesive surface. The root of each layer of eyelash fibers is adhered to one of the adhesive surfaces. All the strip films are fixed together by pressing to form an integral adhesive strip. The adhesive strip has several easy-tear lines, and an easy-tear line is provided between the roots of two adjacent eyelash clusters.

[0007] As a preferred technical solution, a strip of film is adhered to the upper side of the root of the top layer of eyelashes.

[0008] As a preferred technical solution, the upper adhesive side of the top strip of film is covered with a peelable protective film; and / or the lower adhesive side of the bottom strip of film is covered with a peelable protective film.

[0009] As a preferred technical solution, each of the tear lines extends along the vertical direction of the adhesive strip.

[0010] As a preferred technical solution, the root of each layer of eyelashes is bonded to an adhesive surface at room temperature.

[0011] As a preferred technical solution, all the long strip films are fixed together by pressing at room temperature to form an integral adhesive strip.

[0012] As a preferred technical solution, the temperature during the pressing of the elongated diaphragm is between -10° and 180°.

[0013] As a preferred technical solution, the roots of adjacent eyelashes in each eyelash cluster are staggered; or adjacent eyelashes in each eyelash cluster are evenly distributed.

[0014] As a preferred technical solution, each of the elongated membranes can be made transparent, black, or colored.

[0015] As a preferred technical solution, the distance between each tear line and the root of the adjacent eyelash cluster is between 0 and 0.25 mm, the distance between the roots of two adjacent eyelash clusters is between 0 and 5 mm, the width of the root of each eyelash cluster is between 0.1 and 2.0 mm, and the thickness of the strip film is between 0.02 and 0.12 mm.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] Because the freely combinable eyelash extensions consist of multiple long strips of film and multiple sets of eyelash clusters, each eyelash cluster includes multiple layers of eyelash fibers. Since the long strips of film have adhesive surfaces, the roots of the multiple layers of eyelash fibers can be pressed together with the long strips of film, thus fixing the roots of the multiple sets of eyelash clusters together. After the multiple long strips of film are pressed together, they form an adhesive strip with multiple easy-tear lines. These easy-tear lines allow the strip to be manually torn along any of the lines without the aid of tools. This allows individuals to freely select one or more eyelash clusters to wear according to their eye size, enabling free choice of the width of the eyelash extensions. When wearing them, different types of eyelash clusters can be freely combined to suit the length and density of an individual's natural eyelashes. This not only makes the false eyelashes more closely resemble natural eyelashes, improving their realism and aesthetics, but also provides individuals with a variety of wearing options through free combination. Individuals can personalize their false eyelashes by combining one or more different types of eyelash clusters, thus meeting diverse individual needs.

[0018] Compared to traditional thread bonding techniques, this invention uses a room-temperature pressing method to fix the base of the eyelash clusters together, optimizing the false eyelash processing technology. It eliminates the need for heating, making the process simpler, more energy-efficient, and environmentally friendly. Simultaneously, it avoids the glue overflow issues common in traditional thread bonding processes, ensuring the stability of the freely combinable eyelash extension material. The adhesive strip formed by room-temperature pressing has a multi-layered sheet structure, providing a larger bonding area compared to traditional thread adhesive bands, resulting in a more secure fit when worn by an individual.

[0019] Since the adhesive strip has at least one adhesive side on each side, and the adhesive side is covered with a peelable protective film, the adhesive strip has self-adhesive properties when the adhesive side is set. When the entire strip needs to be worn, the protective film can be peeled off and the entire strip can be adhered to the underside or bottom side of the natural eyelashes. Alternatively, false eyelash glue can be applied to the side of the adhesive strip without an adhesive side to achieve the entire strip being adhered to the natural eyelashes. When at least one set of eyelash clusters needs to be worn in a freely combinable manner, after peeling off the protective film, the adhesive strip can be manually torn along the tear line to obtain the required number of eyelash clusters. The eyelash clusters can be adhered to the top or bottom side of the natural eyelashes. Alternatively, false eyelash glue can be applied to the side of the adhesive strip without an adhesive side to achieve the freely combinable wearing of at least one set of eyelash clusters.

[0020] This invention can be worn as a whole strip or in free combination of at least one cluster. It can be attached to the upper or lower side of natural eyelashes, offering a variety of wearing methods. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0032] As shown in Figures 1-8, the free-combination eyelash extension includes multiple strip films 1 and multiple sets of eyelash clusters 2. Each eyelash cluster 2 includes multiple layers of eyelash filaments 3. Each strip film 1 has at least one adhesive surface. The root of each layer of eyelash filaments 3 is adhered to an adhesive surface. All strip films 1 are fixed together by pressing to form an integral adhesive strip 4. The adhesive strip 4 has several easy-tear lines 5. An easy-tear line 5 is provided between the roots 6 of two adjacent eyelash clusters.

[0033] A long strip of film 1 is attached to the upper side of the root of the top layer of eyelashes 3.

[0034] The upper adhesive side of the top strip of film 1 is covered with a peelable protective film 7. And / or the lower adhesive side of the bottom strip of film 1 is covered with a peelable protective film 7.

[0035] Each tear line 5 extends along the width of the adhesive strip 4.

[0036] The base of each layer of eyelashes is bonded to an adhesive surface at room temperature.

[0037] All the long strips of film 1 are fixed together by pressing at room temperature to form a single adhesive strip 4.

[0038] The temperature during the pressing of the long strip diaphragm 1 is between -10° and 180°.

[0039] Each strip of membrane 1 can be made transparent, black, or colored.

[0040] The distance between each tear line 5 and the root of the adjacent eyelash cluster 6 is between 0 and 0.25 mm, the distance between two adjacent eyelash cluster roots 6 is between 0 and 5 mm, the width of each eyelash cluster root 6 is between 0.1 and 2.0 mm, and the thickness of the strip film 1 is between 0.02 and 0.12 mm.

[0041] When wearing customizable false eyelashes, the length of the eyelash extensions can be freely selected between 0.2 and 35 millimeters because the adhesive strip 4 has an easy-tear line 5.

[0042] Since the easy-tear line 5 is set between the roots 6 of two adjacent eyelash clusters, and the distance between the easy-tear line 5 and the roots 6 of the adjacent eyelash clusters is 0.25 mm, it ensures that after tearing the adhesive strip 4 along any easy-tear line 5, the distance between the root 6 of each eyelash cluster and the broken end of the adhesive strip 4 is 0.25 mm. The 0.25 mm adhesive strip 4 does not affect the fixation of the root 6 of the eyelash cluster, nor does it affect the wearing of the eyelash cluster 2, thus realizing the free combination wearing of at least one set of eyelash clusters 2.

[0043] The roots of adjacent eyelash strands 3 in each eyelash cluster 2 are staggered. Example

[0044] This embodiment is basically the same as Embodiment 1, except that adjacent eyelashes 3 are evenly distributed in each eyelash cluster 2.

[0045] In summary, this utility model, by setting easy-tear lines on the adhesive strip, allows the strip to be manually torn along any easy-tear line without the aid of tools. This enables the freely combinable eyelash extensions to be worn as a whole or disassembled into at least one cluster for individual wear. When wearing them, different types of eyelash clusters can be freely combined according to the length and density of individual eyelashes, making the false eyelashes closer to natural eyelashes and improving their realism and aesthetics.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
