Description

The present invention relates to ophthalmic cosmetics, in particular to artificial eyelashes that are secured to the edge of the eyelid, and in particular to rows of artificial eyelashes and methods of making same.

It is a known practice to manufacture a row of artificial eyelashes by manually gluing fibers intended to form false eyelashes to a base portion intended to adhere to the eyelid. However, such manual manufacturing methods are complex and costly. Moreover, manufacturing times can be quite lengthy, thus limiting productivity.

Furthermore, considering the fineness of the fibers that are intended to form the false eyelashes, the false eyelashes are held on the base portion by being glued to the base portion and are applied on a non-planar surface where the adhesion is very narrow. There is a risk that the false eyelashes will come off from the base part.

Patent Document 1 is also known, which patent describes two threads intended to form false eyelashes, both of which are secured by chain stitches, which are also fastened by chain stitches. It relates to an artificial eyelash manufactured by inserting in a zigzag fashion into two base threads each covered by an inserting thread.

This configuration complicates the manufacturing process by forming the false eyelashes from two threads that are inserted in a zigzag pattern and woven together by a chain stitch.

Korean Patent No. 10-1045497

There is a need to easily obtain eyelash configurations that are impossible to obtain manually, have variable curvature, and are more diverse than can be obtained manually.

There is also a need to benefit from manufacturing methods that can reduce manufacturing time and increase manufacturing regularity. In addition, it may be useful to shorten lead times and reduce acquisition costs.

Finally, there is a need to increase the quality of the false eyelash rows obtained by automated iterations, but by simple means to minimize the number of parts in the manufacturing equipment.

Braided False Eyelashes The present invention aims to address all or some of these requirements, and according to one aspect of the invention is a row of artificial eyelashes that secure to the edge of the eyelid, comprising: (i) having a base portion adapted to be secured to the edge of the eyelid; and (ii) false eyelashes;
The above object is achieved by a row of artificial eyelashes whose base part has first warp yarns interwoven by chain stitches and false eyelashes pass through the chain stitches without being tied to the chain stitches.

By “artificial eyelash row” is understood an eyelash row formed from synthetic eyelashes which are not necessarily completely natural eyelashes, in other words false eyelashes.

False eyelashes do not form a chain stitch. False eyelashes do not form a stitch with the first warp thread.

A row of false eyelashes that can be produced simply, quickly and inexpensively is obtained. Furthermore, the false eyelashes can be arranged on the base in various ways.

Furthermore, the row according to the invention has good resistance to use, especially during handling and mounting.

This row is strong, durable and can be easily handled without fear of the false eyelashes coming off the base.

In one embodiment, all false eyelashes in a row are formed from a single weft thread. Therefore, all false eyelashes are formed using only one weft thread. In alternative embodiments, a row may have multiple weft threads, eg, two or more weft threads. It is thus possible to obtain a row of false eyelashes that has a more natural look and in which some false eyelashes cross other false eyelashes.

The base portion may have a first warp yarn interwoven with a chain stitch, and the weft yarn may pass through the chain stitch without being tied to the chain stitch. The weft thread does not form a chain stitch. The weft thread does not form a stitch with the first warp thread. The weft threads alternately pass between the two base parts, which in particular run parallel to each other and symmetrically. In a variant embodiment, it is possible that the two bases are not parallel to each other, but form an angle with each other. This angle may for example have a non-zero value between 0.5° and 70°.

According to this aspect of the invention, there are no two separate weft threads forming every false eyelash.

The first warp may form a closed chain stitch. In a variant embodiment, or additionally, the first warp yarn forms an open chain stitch.

The base portion may have a second warp woven with a chain stitch, and the false eyelashes may pass through the chain stitch without being tied to the chain stitch.

The first warp and the second warp may be knitted. False eyelashes pass through the chain stitch but are not tied to the first and/or second warp threads. The weft threads mentioned above pass through the chain stitch but are not tied to the first and/or second warp threads. The weft thread does not form a stitch with the first warp thread.

The second warp may form a closed chain stitch. In one embodiment, each of the first and second warp yarns form a closed chain stitch. In an alternative embodiment, the first warp yarn forms an open chain stitch and the second warp yarn forms a closed chain stitch.

In an alternative embodiment, or additionally, the second warp thread may form an open chain stitch. In one embodiment, each of the first and second warp yarns form an open chain stitch. In an alternative embodiment, the first warp yarn forms a closed chain stitch and the second warp yarn forms an open chain stitch.

A "chain stitch" is a stitch that forms a loop that is arranged like the links of a chain one after another, i.e., the thread forms a loop that passes over the previous loop, thereby forming a train of stitches. It is understood that

An "open chain stitch" is understood to mean that the two ends of the loop cover the top of the preceding loop with a certain non-zero spacing which is approximately the width of the loop.

A "closed chain stitch" is understood to mean that the two ends of a loop cover the top of the preceding loop with approximately zero spacing, and the two ends are substantially adjacent or even touching. be.

When making open and closed stitches, each stitch is made in the opposite direction. Making both stitches at the same time around a needle with two threads provides a detangling and controllable effect.

The false eyelashes may be regularly distributed over the base part, in particular arranged at regular intervals, eg always the same.

In alternate embodiments, the spacing may be irregular. The spacing may decrease along the base and then increase. The spacing between two consecutive false eyelashes in a row of eyelashes is for example between 0.07mm and 2mm, more preferably between 0.5mm and 1.5mm, or between 0.9mm and 1.25mm, more preferably 0.99mm. to 1.11 mm, for example about 1 mm.

In one embodiment, the false eyelashes may be arranged in groups of false eyelashes, with a first smaller spacing between false eyelashes of the same group and a second larger spacing between two consecutive groups. have A group of false eyelashes may have between 2 and 12, more preferably between 3 and 10, for example 6 or 8 false eyelashes. Each group of false eyelashes in a false eyelash row may have the same number of false eyelashes, or in alternative embodiments, this number varies from group to group along the row of false eyelashes. In one embodiment, the row of false eyelashes has consecutive groups of two false eyelashes, or in a variant embodiment alternating groups of two false eyelashes and groups of eight false eyelashes, for example.

The first and second warp yarns may be made from a first synthetic material selected from, for example, but not limited to, polyolefins, PE, PP, PU, PA, PET, PBT, PES, PTFE. , or heat-activatable adhesives or heat-activatable resins composed of cores of polyolefins, PE, PP, PU, PA, PBT, PES, PTFE, TPU silicone, CoPA, CoPES, TPU, TPE, EVA (ethylene vinyl acetate), polyolefin, polyethylene, polypropylene, PA, PES, PVC coated yarn.

The color selected for the first synthetic material may be similar to or similar to the user's skin color, or in alternative embodiments the synthetic material may be transparent. . The first and second warp yarns may have one or more colors. The first and second warp yarns may have a twist as described below.

The false eyelashes, especially the weft threads, are made of a second material selected from, but not limited to, PE, PP, PU, PA, PET, PBT, PES, PTFE or any other thermoplastic or possibly natural fibres. It may be made from synthetic material. The weft yarn consists of a core of polyolefin, PE, PP, PU, PA, PBT, PES, PTFE, heat-activatable adhesive or heat-activatable resin, TPU silicone, CoPA, CoPES, TPU, TPE, Yarns coated with EVA (ethylene vinyl acetate), polyolefin, polyethylene, polypropylene, PA, PES, PVC may also be used.

It may be possible to have weft threads of different diameters and colors. False eyelashes, especially the weft threads, may have one or more colors. The weft threads may have, for example, one to five different diameters.

The first and second warp threads and/or the false eyelashes, especially the weft threads, may be washed with a washing solution as per Oekotex or REACH standards in order to meet sufficient hygiene requirements.

The base part is knitted to the first warp yarn knitted by chain stitch, in particular the first warp yarn knitted by chain stitch and the additional yarn knitted to the second warp yarn knitted by chain stitch. may have.

This additional thread may help prevent tangling and sticking. Additional yarns may allow the first and/or second warp and weft yarns to further limit the risk of unraveling. The additional thread may be able to provide a reinforcing effect for the base part to which it belongs, which is advantageous for keeping the row of artificial eyelashes in place.

Additional yarns may be added within the base portion comprising the first and second warp yarns interwoven by chain stitch. In alternative embodiments, additional threads may be added in the base portion comprising a single first warp thread interwoven by chain stitch.

This additional thread may extend in a zigzag manner within the base portion.

FIG. 1 shows a row 10 of artificial eyelashes adapted to be secured to the edge of the eyelid. This row 10 has (i) a base portion 12 adapted to be secured to the edge of the eyelid and (ii) false eyelashes 14 .

The base portion 12 has a first warp thread 16 woven by a chain stitch, and the false eyelashes 14 pass through the chain stitch without being tied to the chain stitch. False eyelashes do not form a chain stitch. The false eyelashes are bent into a U shape and the bottom of the U is held by the first warp yarn 16 without knots, as shown.

All false eyelashes 14 in row 10 are formed from a single weft thread T, as shown in the conventional schematic of FIG. 2a. Therefore, all false eyelashes are formed using only one weft thread. In a variant embodiment, there may be more than one weft thread, especially in the case of threads each having a different color. The base portion 12 has a first warp yarn 16 woven by chain stitch, and the weft yarn T passes through the chain stitch without being tied to the chain stitch. The weft thread T passes alternately between the two base parts 12, which extend parallel and symmetrically to each other.

FIG. 2a shows an assembly 20 for forming a row of artificial eyelashes to be secured to the edge of the eyelid, particularly as described above. The assembly 20 has two base parts 12, at least one of which is adapted to be fixed to the edge of the eyelid, arranged parallel to each other and symmetrical with respect to the median plane P. be done.

The assembly 20 also has false eyelashes 14, which are formed from a single weft thread T passing alternately between the two base portions 12. As shown in FIG.

The weft threads are arranged substantially perpendicular to the base portion. The weft threads separate the base parts 12 and are thus intended to be cut between the two base parts, in particular in the median plane P, so as to form a row of artificial eyelashes. The false eyelashes may be regularly distributed over the base part, in particular arranged at regular intervals, eg always the same. Instead of cutting the weft thread in the median plane P between the two bases, it is possible to cut it near one of the two bases. In this case, only one row of artificial eyelashes can be obtained.

In a variant embodiment shown in FIG. 2b, the assembly has three base parts 12 arranged parallel to each other and symmetrically with respect to the median plane P. As shown in FIG. The median plane may for example pass through the central base part and two other base parts may be arranged on each side of the central base part, parallel to each other and symmetrical to the median plane. In this case there are two weft threads T and a single weft thread alternately passes between the two base parts.

In this variant embodiment, the three base parts are parallel to one of the base parts and close to said base part, for example in a first separation plane P′ which is coplanar with said base part, and the base part parallel to one of the parts and close to said base part, for example coplanar with said base part. It is the base part.

In the assembly 20 in Figure 2a, each base portion 12 has a first warp yarn 16 interwoven by a chain stitch, and the weft yarn T passes through the chain stitch without being tied to it. The weft thread does not form a chain stitch. The weft thread does not form a stitch with the first warp thread.

A first warp yarn 16 of the base portion 12 forms a closed chain stitch in the illustrated example. In a variant embodiment, or additionally, the first warp yarn forms an open chain stitch.

In the implementations described above, the row has only one first warp yarn 16 .

In an alternative embodiment, the base portion 12 may have second warp threads 18 interwoven by chain stitches, as shown in the embodiment in Figures 3a-5b. The false eyelashes 14 pass through the chain stitch of this second warp thread 18 without being tied to the chain stitch of this second warp thread 18 . In the assembly 20 in Figures 3a-5b, each base portion has a second warp yarn 18 interwoven by a chain stitch, and the weft yarn passes through the chain stitch without being tied to it. The first warp yarn 16 and the second warp yarn 18 may be interwoven.

The second warp may form a closed chain stitch or an open chain stitch.

In the embodiment shown in Figures 3a and 3b, each of the first and second warp yarns form a closed chain stitch. The closed chain stitches are arranged symmetrically with respect to each other.

In the embodiment shown in Figures 3c and 3d, each of the first and second warp yarns form a closed chain stitch and the closed chain stitches are all superimposed, i.e. each closed chain stitch follows exactly the same path. Further, each of the first and second warp yarns form a closed chain stitch.

In an alternative embodiment, the first warp yarn forms a closed chain stitch and the second warp yarn forms an open chain stitch, as shown in Figures 4a and 4b.

In a further alternative embodiment, each of the first and second warp yarns form an open chain stitch, as shown in Figures 5a and 5b.

In the implementations described above, a row has only one weft yarn. A row may, for example, have two weft threads, as shown by way of example in Figures 5c and 5d. The second weft thread T' does not pass through all the chain stitches of the warp thread in this example. Furthermore, the second weft thread T' intersects the first weft thread T at a predetermined position. This advantageously allows a more natural looking row of eyelashes to be formed, with some false eyelashes intersecting other false eyelashes.

The embodiment of Figure 10 is similar to the embodiment of Figure 3b, with the following differences. In the embodiment of FIG. 10, the base portion 12 has additional yarns 24 interwoven with first warp yarns 16 interwoven with chain stitches and second warp yarns 18 interwoven with chain stitches. In particular, there are two additional threads, one on each base portion 12 .

The assembly 20 may be obtained by a knitting machine 30 as shown in FIG. Knitting machine 30 has compound needles 32 .

A compound needle 32 is formed of a body 33 and a sliding element 34 . The main body 33 is composed of a butting portion 33a, a stem 33b, and a hook 33c. The sliding element 34 consists of a butt 34a and a stem 34b. A sliding element may slide inside the stem of the body to open and close the hook 33c of the needle. The body of the needle and the sliding element therefore move independently and synchronously of each other.

Knitting machine 30 does not have latch needles, particularly with latches connected on stems, and does not have sinkers.

The knitting machine 30 has a thread guide 35 for depositing the weft thread T that will form the false eyelashes. This thread guide moves from right to left and from left to right over compound needle 32 .

Knitting machine 30 also has a first guide bar 36 for feeding first warp yarn 16 . This first guide bar 36 moves right to left and moves left to right, moves top to bottom and moves bottom to top to change the orientation of the compound needle. The side-to-side movement may differ depending on whether the warp yarn 16 is intended to be knitted into an open chain stitch or a closed chain stitch.

Finally, the knitting machine 30 has a second guide bar 38 for feeding the second warp yarns 18 . This second guide bar 38 moves right to left and moves left to right to allow the second warp thread to be deposited on the hook 33c of the compound needle. This second warp yarn 18 makes it possible to fix the first warp yarn 16 better, thereby making the chain stitch of the base portion less likely to unravel. Therefore, the resulting knit can be restrained from loosening.

A method for manufacturing a row of artificial eyelashes will now be described.

In the first step (a), the assembly 20 is knitted by compound needles. The assembly 20 comprises two base portions 12 arranged parallel to each other and symmetrical to the median plane P, with at least one base portion 12 between them being fixed to the edge of the eyelid. , and false eyelashes 14 formed from a single weft thread T passing alternately between the two base portions.
