Description

Curved eyelash extensions Technical Field

[0001] This utility model relates to the field of false eyelash technology, and in particular to an arc-shaped eyelash extension. Background Technology

[0002] In the current process of attaching false eyelashes, adhesive binds the polyester thread to the base of the false eyelashes, forming a single adhesive band. Because the polyester thread is stretched straight during placement, the resulting adhesive band is also straight. When wearing existing false eyelashes, the adhesive is applied to the adhesive band before being glued to the individual's natural eyelashes. However, since the individual's eye contour is curved, and the adhesive band is straight, it cannot conform to the curved eye contour, reducing the comfort of wearing the false eyelashes. The ends of the adhesive band need to be bent inwards before it can be glued to the individual's false eyelashes. Furthermore, because the adhesive band is stiff and inelastic, the ends of the adhesive band tend to curl up after wearing the existing false eyelashes.

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

[0004] This invention proposes an arc-shaped eyelash extension, which features an arc-shaped adhesive part on a long strip of film. After the adhesive part is pressed together, an arc-shaped connecting strip is formed. The arc-shaped connecting strip has a higher degree of fit to the individual's eye contour and avoids the occurrence of the two ends of the strip lifting up after wearing.

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

[0006] The arc-shaped eyelash extension includes multiple strips of film and multiple layers of eyelash fibers. Each strip of film is provided with an arc-shaped adhesive part, and the arc-shaped adhesive part is provided with at least one adhesive surface. The root of each layer of eyelashes is adhered to one of the adhesive surfaces. All the strips of film are fixed together by pressing to form a single adhesive strip. The corresponding adhesive parts are pressed together to form an arc-shaped adhesive strip.

[0007] As a preferred technical solution, a connecting part is provided between the two adhesive parts, and after all the connecting parts are pressed together, a connecting strip is formed for connecting the two adhesive strips.

[0008] As a preferred technical solution, the lash-adhesive portion protrudes towards the side where the eyelash strands are located, forming the arc shape.

[0009] As a preferred technical solution, all the elongated diaphragms are fixed together by pressing at room temperature.

[0010] As a preferred technical solution, the lint-adhesive part is configured in a single arc, and a single arc adhesive strip is formed after the lint-adhesive part is pressed together.

[0011] As a preferred technical solution, the lint-adhesive part is configured with a double arc, and a double arc adhesive strip is formed after the lint-adhesive part is pressed together.

[0012] As a preferred technical solution, at least one easy-tear line is provided at the connection point of adjacent arcs on the double-arc adhesive strip, and each easy-tear line extends along the vertical direction of the double-arc adhesive strip.

[0013] As a preferred technical solution, the lint-adhesive part is provided with three arcs, and a three-arc adhesive strip is formed after the lint-adhesive part is pressed together.

[0014] As a preferred technical solution, at least one easy-tear line is provided at the connection point of adjacent arcs on the three-arc adhesive strip, and each easy-tear line extends along the vertical direction of the three-arc adhesive strip.

[0015] As a preferred technical solution, an easy-tear line is provided at the connection between the connecting strip and the adhesive strip.

[0016] As a preferred technical solution, the temperature during the pressing of the elongated diaphragm is between -10° and 180°.

[0017] As a preferred technical solution, the elongated membrane can be made transparent, black, or colored.

[0018] As a preferred technical solution, the thickness of the elongated diaphragm is between 0.02 and 0.12 mm.

[0019] As a preferred technical solution, the adhesive strip has at least one adhesive surface on each side, and the adhesive surface is covered with a peelable protective film.

[0020] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0021] Because the curved eyelash extensions include adhesive strips and the hair-adhesive parts on the long film, all the hair-adhesive parts are pressed together to form a curved adhesive strip. When wearing eyelash extensions, the curved connecting adhesive strip is more compatible with the individual's eye contour, making the eyelash extensions more comfortable to wear and preventing the two ends of the adhesive strip from lifting up after wearing.

[0022] Because there is a connecting strip between the two adhesive strips, the connecting strip makes the two adhesive strips a single unit. Since eyelash extensions are usually used in pairs, the adhesive strip makes it easier to package the eyelash extensions in pairs. Before applying the eyelash extensions, simply tear off the connecting strip between the two adhesive strips along the tear line.

[0023] Since the adhesive part can be set as a double arc or a triple arc, and the adhesive strip is formed after the corresponding adhesive parts are pressed together, the connection of the arc on the adhesive strip is provided with an easy-tear line. When using the adhesive strip, the adhesive strip can be torn along the easy-tear line at the arc connection. The torn adhesive strip can be divided into an adhesive strip with an arc structure. Individuals can attach the above adhesive strip to their natural eyelashes according to the contour of their eyes. Individuals can also match different types of eyelash extensions according to the density and length of their natural eyelashes, thereby achieving high adaptability and high realism of eyelash extensions.

[0024] The easy-tear design allows individuals to separate the eyelash extensions into adhesive strips with an arc-shaped structure without the need for tools, making the segmentation of the adhesive strips simpler and more convenient when wearing arc-shaped eyelash extensions.

[0025] Since the adhesive strip has at least one adhesive side on each side, and the adhesive side is covered with a peelable protective film, after the adhesive strip is cut into adhesive strips with an arc-shaped structure, the protective film can be peeled off. The setting of the adhesive side makes the eyelash extension self-adhesive, and it can be attached to the upper or lower side of the natural eyelashes without applying false eyelash glue. The eyelash extensions in this utility model are simple, convenient and highly adaptable to wear. Attached Figure Description

[0037] 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

[0038] As shown in Figures 1-10, the arc-shaped eyelash extension includes multiple strips of film 1 and multiple layers of eyelash strands 2. Each strip of film 1 is provided with an arc-shaped sticking part 3, and the arc-shaped sticking part 3 is provided with at least one adhesive surface. The root of each layer of eyelashes is adhered to an adhesive surface. All the strips of film 1 are fixed together by pressing to form an integral adhesive strip 4. The corresponding sticking parts 3 are pressed together to form an arc-shaped adhesive strip 5.

[0039] A connecting part 6 is provided between the two adhesive parts 3. After all the connecting parts 6 are pressed together, a connecting strip 7 is formed to connect the two adhesive strips 5.

[0040] The tufted part 3 protrudes towards the side where the eyelashes 2 are located and forms an arc shape.

[0041] All the long strip diaphragms 1 are fixed together by pressing at room temperature.

[0042] As shown in Figure 2, an easy-tear line 16 is provided at the connection between the connecting strip 7 and the adhesive strip 5.

[0043] The temperature during the pressing of the long strip diaphragm 1 is between -10° and 180°.

[0044] Compared with the traditional thread bonding process, this utility model uses a room temperature pressing method to fix the two eyelash strands together, optimizing the false eyelash processing technology. It eliminates the need for heating, making the false eyelash processing simpler, more energy-efficient, and environmentally friendly. At the same time, it avoids the glue overflow that occurs in the traditional thread bonding process, thus ensuring the stability of the curved eyelash extension material. The adhesive strip 4 formed by room temperature pressing has a multi-layer sheet structure, which can bond a larger area than the traditional thread adhesive band, making the curved eyelash extensions more secure when worn by an individual.

[0045] The strip membrane 1 can be set to any of the following: transparent, black, or colored.

[0046] The thickness of the long strip diaphragm 1 is between 0.02 and 0.12 mm.

[0047] At least one adhesive surface is provided on each side of the adhesive strip 4, and a peelable protective film 8 is covered on the adhesive surface.

[0048] The adhesive strip 4 comprises the following components by weight: 60%-70% SBS, 20%-30% tackifying resin, and 5%-10% plasticizer.

[0049] In this invention, the adhesive strip 4 is a solvent-free adhesive strip that is non-toxic and toluene-free, reaching the cosmetic grade. Compared with the thread adhesive strip formed by the existing thread bonding process, the adhesive strip 4 in this invention is softer and has a certain degree of elasticity, making it more comfortable for individuals to wear and more in line with the individual's eye contour.

[0050] The lint-adhesive part 3 is designed in a single arc, and after pressing the lint-adhesive part 3 together, a single arc adhesive strip 9 is formed. Example

[0051] As shown in Figures 5 and 6, this embodiment is basically the same as the first embodiment, except that the lint-adhesive part 3 is set in a double arc, and the double arc adhesive strip 10 is formed after the lint-adhesive part 3 is pressed together.

[0052] An easy-tear line 16 is provided at the connection point of adjacent arcs on the double-arc adhesive strip 10, and the easy-tear line 16 extends along the vertical direction of the double-arc adhesive strip 10. Example

[0053] As shown in Figure 7, this embodiment is basically the same as embodiment 2, except that two or more easy-tear lines 16 are provided at the connection of adjacent arcs on the double arc adhesive strip 10. Example

[0054] As shown in Figure 8, this embodiment is basically the same as the first embodiment, except that the lint-adhesive part 3 is provided with three arcs, and the three-arc adhesive strip 11 is formed after the lint-adhesive part 3 is pressed together.

[0055] An easy-tear line 16 is provided at the connection point of adjacent arcs on the three-arc adhesive strip 11, and the easy-tear line 16 extends along the vertical direction of the three-arc adhesive strip 11. Example

[0056] As shown in Figure 9, this embodiment is basically the same as embodiment four. The difference is that two or more easy-tear lines 16 are provided at the connection of adjacent arcs on the three-arc adhesive strip 11.

[0057] In summary, this utility model provides an arc-shaped lint-adhesive section on a long strip of film, which, when pressed together, forms an arc-shaped connecting strip. This arc-shaped connecting strip has a higher degree of fit to the individual's eye contour, preventing the two ends of the strip from lifting up after wearing.

[0058] 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.
