Abstract

Disclosed is a rapid and efficient method for producing false eyelashes which can be easily attached and do not shift or become detached during wearing. The production method includes a step of supplying a base comprising an ultra-thin flat surface having an adhesive layer formed on the rear surface thereof; a step of supplying adhesive which forms an adhesion layer on the front surface of the base; a step of affixing hair material to the adhesive; and a step of drying the adhesive. The drying step causes the adhesive to form an adhesion layer while the base remains in a two-dimensional shape. If the base (1) is to be made into a three-dimensional shape, the hair material (3) is affixed while the adhesive forming the adhesion layer (4) is in a semi-dried state, and the drying step produces the three-dimensional shape. The hair material (3) is securely affixed to the adhesion layer while remaining in a linear arrangement on the base (1), and therefore it is possible to rapidly and efficiently produce false eyelashes with the hair material (3) remaining in an orderly aligned state.

Description

Method for manufacturing false eyelashes

The present invention relates to a method for producing false eyelashes.

In the conventional false eyelashes 103, as shown in FIG. 12, artificial eyelashes were planted on an ultrathin linear base 101 having a width of about 0.5 mm, and adhered to the eyelid just above the eyelashes 122 with an adhesive. Further, as shown in FIG. 13, there is a type in which the eyelashes 122 are dropped and attached to the other reinforcing portions in a dotted shape using tweezers or the like at a level of usually one to several locations.

In the past, since an adhesive was used for sticking, there was a risk that if one step was mistaken, the eyes could be damaged. Therefore, the sticking work was performed carefully, but it was not very successful and took time. Sometimes it could result in use in a state where it could not be applied well.

This is due to the following reason. As shown in FIG. 14, since the conventional false eyelashes are linear, the false eyelashes are deformed in various ways at the time of sticking, but the deformation is both in the vertical direction and in the horizontal direction, and is deformed in all directions of 360 degrees. . Adhesion of false eyelashes, even at the lower end of the upper eyelid, it is very difficult to align the position of sticking deformable linear eyelashes, and it requires a high level of skill. Because.

Also, even if it was able to stick well, the sticking area was very small, linear or dotted, so it was very unsightly that it could shift due to the vertical movement of the lid during mounting.

Conventional eyelashes have a base 101 that is linear or dot-shaped and has a small adhesion area, so that the usage time is short, and the base eyelashes may fall off or shift due to face washing.

Furthermore, since an adhesive containing a solvent was used, the eyes could not be opened for a certain period of time due to the volatilization of the solvent after mounting.

Furthermore, when wearing on the eyelid or during wearing, both ends of the linear base hit the eyelid, causing pain to the wearer. In addition, since a linear object is attached, there is a disadvantage that even if the duration of the attachment is long, it is as short as about 6 hours and is easily detached by face washing or tearing.

Therefore, the present applicant proposed Patent Document 2, which still had the following difficulties.

In other words, the false eyelashes according to Patent Document 2 were developed for use in wigs, that is, a base in which irregularities appear on the back surface when hair material is planted and the unevenness on the back surface is reversed when worn on the head. For this reason, it is not practical to attach the eyelids on the back of the base, which can be expected in a large area like a wig. The reason for this is that the eyelid belongs to the thinnest part of the skin of the human body and is usually about 10 to 20 μm, and it is not appropriate to apply a large pressure as in the case of wearing the head.

Therefore, only the adhesive layer attached to the convex part on the back of the base was attached to the eyelid, and the adhesive layer attached to the concave part was very difficult to attach to the eyelid.

As a result, a gap was formed between the concave portion and the eyelid, so that the mounting force was reduced and the duration of the mounting was also reduced, and there was a possibility that moisture could easily enter the concave portion due to face washing or tears and easily come off.

The object of the present invention is to eliminate the above-mentioned drawbacks. Specifically, the eyelashes that can be easily attached while keeping the hair materials arranged in an orderly manner, and quickly and efficiently produce false eyelashes that do not shift or become detached during the attachment. It is to provide a manufacturing method that can be performed. Other purposes will be made clear from the following description.

In order to achieve the above object, the method for manufacturing false eyelashes according to the present invention includes a step of supplying a base made of an extremely thin flat surface having an adhesive layer formed on the back surface, and an adhesive serving as an adhesive layer on the surface of the base.

Next, the method for producing false eyelashes according to the present invention will be described in more detail based on the drawings showing the embodiments. For convenience, portions having the same function are denoted by the same reference numerals and description thereof is omitted.

In FIG. 1, reference numeral 1 denotes a base, which is made of an extremely thin sheet (for example, 20 μm thick) of the human skin. The base 1 is made of a stretchable material such as polyurethane, has a transparent and light skin color, and is formed in a three-dimensional shape so as to match the curved shape of the upper eyelid. The base 1 is provided with a blank portion 2a along the longitudinal direction at the lower end portion 1c of the surface, and the adhesive layer 4 is formed at the lower end portion 1c leaving the blank portion 2a. In addition, margin portions 2 b having substantially the same size are provided at both end portions of the adhesive layer 4. The adhesive layer 4 is made of a UV curing agent, is formed linearly on the base 1 (shown in FIG. 6B), and the hair material 3 is adhered thereto. 1d is an upper end portion of the base 1 formed in a projecting arc shape. An adhesive layer 7 made of a medical adhesive for attaching to the human body is formed on the entire back surface of the base 1. The pressure-sensitive adhesive layer 7 is made of, for example, an acrylic pressure-sensitive adhesive, and is formed with a uniform thickness on the entire back surface of the base 1 by a transfer method. That is, the release paper on one side of the acrylic pressure-sensitive adhesive having release paper (PET) provided on both sides is peeled off and the surface is fixed to the entire back surface of the base 1, and the release paper 9 on the other side is peeled off during use. Affix to the application site of the upper eyelid 20 (shown in FIGS. 7A to 7C). Reference numeral 3 denotes a hair material individually attached to the base 1 in a separated state, and is made of, for example, polyester fiber. The hair material 3 is formed by curling the tip portion upward.

The root portion 5 of the hair material 3 is formed in a spherical shape and is adhered to the adhesive layer 4. This sticking is performed such that the root portion 5 is positioned at the lower end portion 4a of the adhesive layer 4 as shown in FIG. The reason will be described later.

In the embodiment of FIG. 1, the base 1 is bent into a three-dimensional shape after being cut into a predetermined shape of false eyelashes as will be described later. At this time, when the length f of the base end portion 1c of the base 1a is larger than the length i (shown in FIG. 8A) of the upper eyelid 20 from the human eye to the corner of the eye (f> i). , The same case (f = i) and the small case (f <i) can be considered. As a result of the experiment, if large (f> i), the same effect as that of the embodiment shown in FIG. 2, that is, the effect of preventing the eyelashes from falling off due to the base 1 having the margins 2a and 2b, etc. It has been found. This will be described later with reference to FIG. Further, in the case where they are the same (f = i), in addition to the above, it has been found that, compared with the embodiment shown in FIG. So desirable. In the case of a smaller size (f <i), in addition to the above, in comparison with the embodiment shown in FIG. 2, the attachment to the upper collar 20 becomes easier and the generation of wrinkles on the base end 1c is prevented. It is further desirable because it has been found to prevent further.

FIG. 2 shows a second embodiment of false eyelashes manufactured by the method for manufacturing false eyelashes according to the present invention. The base 1 in this embodiment is formed in a substantially flat shape that is not customized. The hair material 3 is attached to the adhesive layer 4 in a state where it is connected by the linear member 31. The rest of the configuration is the same as in the embodiment of FIG.

FIG. 3 shows the base 1 used for the false eyelashes of FIG. Here, the margin part will be described. The size of the margins 2a and 2b is set to be smaller than the diameter of one hair. Specifically, it is desirable that a ₁ = about 0.1 mm to about 0.6 mm and a ₂ = about 0.1 mm to about 0.6 mm. In this embodiment, the base 1 has a Japanese eye size i (shown in FIG. 8A) of about 30 mm on average, so the length L is about 26 mm, and the maximum width is for single use. W ₁ = about 2.6 mm, for duplex, and for back duplex W ₂ = about 4 mm. Since there are various shapes of the base 1 depending on the shape of the applied eyelid, as will be described later with reference to FIG. 7, in FIG. 3, the maximum width is generically represented as “W”.

Here, the hair material 3 will be described. In the present embodiment, a plurality of hair materials 3 individually attached in a separated state are attached to the adhesive layer 4 in a state of being connected by a linear member 31. There are various modes of the hair material 3. For example, a large number of hair materials 3 are entangled (entangled) or bound to a single or a plurality of linear members 31. For example, FIGS. 4A and 4B show a case where a large number of hair materials 3 are sandwiched between two intertwined linear members 31 and 31 and inserted into the adhesive component of the adhesive layer 4. 4C and 4D show a case where a large number of hair materials 3 are sandwiched between two parallel linear members 31 and 31 and inserted into the adhesive component of the adhesive layer 4. 4E and 4F show a case where a large number of hair materials 3 are bonded to one linear member 31 with an adhesive and inserted into the adhesive component of the adhesive layer 4 in this state. FIGS. 4G and 4H show a case where a large number of hair materials 3 are bound to one linear member 31 and inserted into the adhesive component of the adhesive layer 4 in this state. Examples of the linear member 31 include a thread and a teg. The length d of the hair material 3 is about 2 mm to 12 mm. The width e of the hair material 3 to be attached is about 10 mm to 50 mm. Each hair material 3 is curled upward from the stage of the hair material unit 3A shown in FIGS. 4A to 4H, and the hair material 3 near the center is formed longer than the other portions.

The above-described embodiment of FIGS. 1 and 2 is shipped after being cut into a predetermined shape of false eyelashes at a factory, but the third embodiment of the present invention shown in FIG. is there. In this case, the base 1 is cut into a square shape 1M larger than a predetermined shape of false eyelashes. The user himself uses the false eyelash base 1 cut into a predetermined shape along the cut line shown in FIG. In FIG. 5A, “1a” indicates the base after separation. The rest of the configuration is the same as in the embodiment of FIG.

Here, the size of each part of the false eyelashes shown in FIG. 5 will be explained. The vertical size of the base 1 before use is a personal size that is cut to the size of about 20 mm to 30 mm for business use and to the vicinity of the base end 1c. b is about 10 mm to about 15 mm, and the horizontal size c is formed about 10 mm to about 40 mm. The length d of the hair material 3 is about 2 mm to 12 mm. Each hair material 3 is curled upward from the stage of the hair material unit 3A (shown in FIG. 6C), and several near the center are formed longer than the other portions. The width L (shown in FIG. 1 (A)) to which the hair material 3 is attached is about 10 mm to 50 mm. In the case of the present embodiment, the base 1a has a Japanese eye size i (shown in FIG. 8A) of about 30 mm on average, so the length L is about 26 mm, and the maximum width W is for single use. About 2.6 mm, and for double and back duplex are about 4 mm. The shape of the base 1 varies depending on the shape of the applied eyelid, as described with reference to FIG.

In addition, FIG.1, FIG.2 and FIG.5 is a schematic diagram, and the planting number of the hair material 3 is simplified and shown.

<Manufacturing process>
The method for producing false eyelashes according to the present invention is, for example, as follows. Here, it demonstrates based on the false eyelashes shown in FIG.

First step (base supply step)
The base 1 for one section is supplied from the long base base material 1M wound on the reel 13 on the work position T of the work table 12 (FIG. 6A). A medical adhesive for attachment to the human body is formed as an adhesive layer 7 on the back surface of the base base material 1M, and a release paper 9 is pasted on the back surface.

Second step (adhesive supply step)
An adhesive to be the adhesive layer 4 is supplied to an appropriate position of the base 1 for one section (FIG. 6B). For convenience, two adhesive layers 4 are disposed in the horizontal direction in FIGS. 6B and 6D. However, the adhesive layers 4 are provided on the base base material 1M for one section so as to obtain a suitable number of yields. . The adhesive is supplied in a straight line by horizontally moving a supply pipe (not shown) on the base 1 fixed on the work table.

Third step (hair material cutting step)
A hair material unit 3A, to which the base end portion 3b of the hair material 3 is connected, is held by a pair of openable / closable robot shafts 15, and in this state, a gap between the base end portion 3b and the robot shaft 15 is shown by a laser beam (not shown). Cut (FIG. 6C). The cut line L is indicated by a one-dot chain line in FIG.

Fourth step (hair material sticking step)
Even after the cutting is completed, the hair material continues to be gripped by the robot shaft 15, and the hair material cut in the gripped state by the adhesive (which forms the "adhesive layer 4") applied in the above process. Is attached by lowering the robot shaft 15 (FIG. 6D). The hair material 3 is attached to the lower end portion 4a (shown in FIG. 5F) of the adhesive layer 4 by appropriately adjusting the position of the robot shaft 15.

5th process (Production process)
Thus, when the hair material is attached to the base 1, the adhesive is dried, and the base 1 is formed in a two-dimensional shape. Then, the base 1 is cut into one section indicated by a one-dot chain line M in FIG. In the false eyelashes shown in FIG. 2, the base 1 is shipped by being cut into a predetermined shape by the laser beam R based on the cut line shown in FIG. The cutting of the base 1 with the laser beam R will be described later with reference to FIG. Further, in the false eyelashes shown in FIG. 1, after the hair material 3 is stuck in the semi-dried state of the adhesive layer 4, the base 1 is made into a predetermined three-dimensional shape and dried in this state. Thus, the adhesive is dried to form the adhesive layer 4, and the base 1 is formed in a predetermined three-dimensional shape.

Next, the base 1 for the next one section is supplied onto the work position T, and the above-described work is performed. Such an operation is continuously repeated.

FIG. 7 shows a size pattern scale 11 of false eyelashes. FIG. 7A shows a scale used when the eye size is large, FIG. 7B shows the same size, and FIG. 7C shows a scale used for partial mounting. 11B represents the right eye. In each pattern, a cut line 11d cut along the base end portion 3b is formed in a straight line, and the cut lines 11a, 11b, and 11c at the tip end portion are upward curves 21a of the eyeball 21 (shown in FIG. 8A). It is formed in a salient arc-shaped curve that is patterned to match

7A and 7B, “11a” is a cut line for forming a double or back duplex formed at a maximum of 5 mm, and “11b” is a rear line formed at a maximum of 4 mm to 3 mm. “11c” indicates a cut line for forming a double or single layer, and “11c” indicates a cut line for forming a double or single layer formed at a maximum of 2 mm. Although the length of the cut line 11d in FIG. 7A is 30 mm and the length of the cut line 11d in FIG. 7B is 23 mm, it can be appropriately cut according to the size of the eyes. In FIG. 7C, “11a” is a cut line for forming a double or a double or more formed at a maximum of 5 mm, and “11b” is a double or a back duplex formed at a maximum of 4 to 3 mm. Each shows a cut line for forming the. Although the length of the cut line 11d is 15 mm, it can be appropriately cut according to the size of the portion to be mounted.

<Usage>
The false eyelashes according to the present invention may be produced in a state of being cut into a predetermined shape as shown in FIGS. 1 and 2, or may be a user cut specification indicated by “1M” in FIG. In the former case, the release paper 9 can be peeled off and directly attached to the upper eyelid. In the latter case, the base 1 is first placed on the desired size pattern scale 11 shown in FIG. Place in state. Next, the user draws a cut line indicated by the size pattern scale 11 on the base 1. Next, the base 1 is cut along the cut line by the user. Next, the release paper 9 is peeled off, and the sticking surface is stuck to the eyelid for use.

<Laser cutting effect>
In each said Example, since the hair material 3 is cut | disconnected and taken out from the hair material unit 3A with a laser beam, there exists the following effect.

A. Non-contact cutting Since the cutting with the laser beam is non-contact, the hair material 3 is scattered at the time of cutting, and the directionality does not vary. Further, since the hair material unit 3A is cut by the laser beam while being gripped by the robot shaft 15, only the continuous portion is cut while the direction of the curled hair tip is curled upward, and each hair material 3 is cut. Can be separated. Therefore, the alignment of the hair material 3 can be maintained.

(B) Heat cutting Since heat is generated at the time of cutting with laser light, the root portion 5 of each cut hair material 3 is melted by heat and becomes spherical. For this reason, the spherical root portion 5 can be referred to as “glue allowance”, and it is not necessary to provide a separate process for creating “glue allowance” for bonding to the base 1. Thereby, false eyelashes can be manufactured quickly and efficiently.

Since the root part 5 of the hair material 3 is formed in a spherical shape, any part of the spherical surface of the root part 5 can be attached to the adhesive layer 4, while each hair material 3 is gripped by the robot shaft 15, In addition, since the direction of the curled hair tips can be firmly attached to the adhesive layer 4 in an aligned state, each hair material 3 is point-bonded, but the direction of the hair tips varies greatly. Instead, it can be fixed to the surface of the base 1 in a predetermined direction, that is, in a state curled upward. Therefore, since the conventional uneven surface is not formed on the back surface of the base 1, the intrusion of moisture or the like during the mounting is prevented, so that the false eyelashes are prevented from being displaced or detached. In addition, since the hair material 3 is firmly attached to the adhesive layer 4 while being linearly arranged on the base 1, false eyelashes are quickly and efficiently manufactured while the hair material 3 is in an orderly arrayed state. be able to.

C. The effect of spreading the eyelids, the effect of being integrated with the own hair Each hair material 3 is stuck to the base 1 in a separated state while maintaining the curled state upward, but when attached to the eyelids, Since the upper collar 20 is opened in a projecting shape as described later, each root portion 5 of each attached hair material 3 also has a projecting shape along the upper collar 20. As a result, each hair material 3 adhered in parallel has a radial angle, and the gap formed between the hair materials 3 is further expanded.

Since the line of each hair material 3 is pasted immediately above the own eyelashes 22 as shown in FIGS. 8A to 8C, the self eyelashes 22 show their faces from the widened gaps, and each hair It is on the same line as the line of material 3. Therefore, there is an effect that the attached false eyelashes are integrated with the own hair.

D. Effect in which the root portion of the hair material 3 is formed in a spherical shape Since the root portion 5 of the hair material 3 is formed in a spherical shape, any portion of the spherical surface of the root portion 5 can be attached to the adhesive layer 4. Therefore, since the sticking angle of the hair material 3 can be adjusted, a product can be grouped according to a use and expansion of a product can be aimed at. For example, if the hair material 3 is attached to the adhesive layer 4 in an orthogonal shape, the eyelashes appear to be large, so that it is suitable for young people. For elderly people.

Moreover, since any part of the spherical surface of the base part 5 can be adhered to the adhesive layer 4, a rapid and efficient production is possible.

<Other effects>
The above-described embodiments have the following effects.

The false eyelashes manufactured by the method for manufacturing false eyelashes according to the present invention have a sticking surface that is wide in the form of a surface, and this wide sticking surface is stuck to the upper eyelid 20. In this sticking, since the base 1 has a planar shape, the base end 1c is substantially linear and the tip 1d is formed in a projecting shape, the deformation of the base 1 is conventionally performed in all directions of 360 °. In contrast to the deformation, as shown in FIG. 9, there is only one direction (vertical direction), and other deformations can be substantially ignored.

Therefore, when attaching false eyelashes, the positioning of the hair material 3 to the lower edge of the upper eyelid 20 becomes very easy, coupled with the fact that the surface of the base 1 to be handed is a wide and easy-to-handle surface, and the labor and time of the mounting work. Can save a lot. Moreover, since the sticking surface is planar and the area to be stuck to the upper eyelid 20 is large, there is no possibility that the false eyelashes are displaced or detached during the wearing. In this case, as in the embodiment of FIG. 1, when the base 1 is formed in a three-dimensional shape along the curved shape of the heel to which the base 1 is attached, the goodness and ease of attachment to the upper heel 20 are provided. Is further improved.

Here, the goodness and ease of attachment to the upper arm 20 will be described in more detail in relation to the cutting effect by the laser beam described above. First, since the hair material 3 is linearly cut by the laser beam in the gripped state, the root portion 5 of the hair material 3 is formed in a spherical shape, and any portion of the spherical surface of the root portion 5 is attached to the adhesive layer 4. can do. Therefore, the curled hair tips can be easily attached to the upper eyelid 20 with the directionality thereof being aligned.

Moreover, when the base 1 is stuck along the own hair of the lower edge of the upper collar 20, since the root part 5 of the hair material 3 is stuck to the lower end part 4 a of the adhesive layer 4, the stuck hair material 3, the base 1 can be cut in a marginal manner, leaving a slight margin 2 a. For this reason, since the own eyelashes 22 and the hair material 3 overlap on substantially the same line as shown in FIG. 8 (A) to FIG. 8 (C), they cannot be distinguished from the own eyelashes 22, and thus the appearance is very good. It becomes good. In addition, since the remainder of the adhesive layer 4 does not enter the field of view, the field of view is improved. That is, when the root part 5 of the hair material 3 is attached to the center part of the adhesive layer 4, not only the self-lashes 22 and the hair material 3 are doubled up and down, but the appearance of the hair layer 3 is not adhesive. Since the remainder of 4 enters the field of view, the field of view becomes foggy and worsens, but this is prevented.

This point will be further described. In order to cut the base 1 into the predetermined shape shown in FIGS. 1 and 2, the laser beam R is irradiated from the back surface of the base 1. This is because if the laser beam R is irradiated from the surface of the base 1, “burning” occurs in the base sheet, resulting in a defective product. In this cutting, as shown by a one-dot chain line in FIG. 10 (A), if the laser beam R is irradiated at right angles along the last line of the base 1, particularly the hair material 3, the hair material 3 may be damaged. Many. Therefore, as shown by a solid line in FIG. 10A, the laser beam R is irradiated with being inclined with respect to the adhesive layer 4 (for example, inclined at about 60 ° with respect to the adhesive layer 4) to cut the base 1. If it does in this way, it will prevent that the hair material 3 stuck by the contact bonding layer 4 vicinity is damaged. However, when the laser beam R is inclined and irradiated in this way, all or a part of the adhesive layer 7a formed on the back surface of the base 1 is melted and falls off or partially peels from the back surface. In this case, when the upper arm is attached to the upper eyelid, the ability to attach to the upper eyelid is lost, and not only the attachment force is reduced, but also when a part of the base 1 is peeled off from the upper eyelid, the base 1 is placed between the upper eyelid. Since a gap is formed, it becomes very false eyelashes and can easily be distinguished from natural hair in appearance.

Further, as shown by a solid line in FIG. 10A, when the laser beam R is applied to the adhesive layer 4 while being inclined, a part of the adhesive layer 4 to which the hair material 3 is adhered may be destroyed and damaged. Then, the hair material 3 may fall off the base 1.

In the present embodiment, as indicated by a solid line in FIG. 10B, the laser beam R is irradiated with being inclined (for example, inclined at about 60 ° with respect to the base 1) with respect to the portion to be the lower end portion 1c. Since the margin portion 2a is provided along the longitudinal direction with respect to the lower end equivalent portion 1c of the surface of the base 1, and the margin portions 2b having substantially the same size are also provided at both end portions of the adhesive layer 4, the hair material 3 is not damaged, and the output of the laser beam R can be made small, so that the adhesive layer 7 in the vicinity of irradiation is also prevented from dissolving. Therefore, it is possible to prevent the fallen eyelashes from falling off the upper eyelashes and to prevent the hair material 3 from dropping from the base 1. In addition, since the laser beam R is irradiated from the back surface of the base 1, there is no possibility of “burning” in the base sheet.

The hair material 3 is affixed to the bottom of the base 1 with a margin 2a that is not noticeable to the naked eye. For this reason, since the own eyelashes 22 and the hair material 3 overlap on substantially the same line as shown in FIG. 8 (A) to FIG. 8 (C), they cannot be distinguished from the own eyelashes 22, and thus the appearance is very good. It becomes good. In addition, since the remainder of the adhesive layer 4 does not enter the field of view, the field of view is improved. In other words, if the hair material 3 is not attached to the last minute of the base 1, not only the self eyelashes 22 and the hair material 3 are doubled up and down, but the appearance of the adhesive layer 4 is not visible. As it comes in, it gets worse as fog gets on the field of view, but this is prevented.

Moreover, since the margin part 2b is left also in the both ends of the base 1, since the hair material 3 is not affixed here, the hairline of the self eyelash 22 and the affixing site | part of the hair material 3 correspond. Therefore, there is an effect that the false eyelashes to be processed become more natural.

Furthermore, eyeline cosmetics (not shown) can be applied to a slight gap g (shown in FIG. 8C) formed between the blank portion 2a and the self eyelashes 22.

Furthermore, in the case of the embodiment shown in FIGS. 2 and 5, the base 1 is formed in a planar shape and is not processed for a specific user in both two dimensions and three dimensions. In the case of the user cut specification shown in FIG. 5, the upper space 1b (shown in FIG. 5 (A)) of the attached base 1 has a sufficient area so that it can be freely cut. The part 1d can be used by cutting into a salient shape. Thereby, there exists an effect which raises the skin of the upper eyelid 20 upwards.

The skin of the upper eyelid 20 deteriorates over time and gradually becomes slack, but this lifting effect adjusts the cut area according to the degree of sagging of the skin of the upper eyelid 20 and raises the upper eyelid 20 upward. The eyes can be made more crisp and an anti-aging effect is produced.

Furthermore, in the case where the base 1 is formed in a flat shape and the hair material 3 is formed in a straight line at the lower end of the base 1, when the base 1 is attached to the upper collar 20, the base 1 has a projecting arc shape. Since it becomes a salient arc shape along the upper collar 20, each hair material 3 stuck in the individual separation state is radially expanded. For this reason, the line of eyelashes (actually "false eyelashes") looks dark and the eyes look very large.

The method for producing false eyelashes according to the present invention is not limited to the above-described embodiments. For example, regarding the cutting of the base, the irradiation direction of the laser light is arbitrary as long as it has a predetermined inclination angle with respect to the base. For example, the irradiation may be performed from below to above.

The hair material 3 may have a curved base shape other than a spherical shape (for example, an arc shape), and the hair material 3 is cut into a flat shape by a cutter or the like as shown in FIGS. 11 (A) and 11 (B). However, it has the same effect as described above.

Moreover, the sticking angle of the root part 5 of each hair material 3 is not orthogonal as in each of the above illustrated examples, but can also be inclined downward as shown in FIG. In this case, the inclination angle may be 45 °, for example, but is appropriately selected depending on the user's purpose, age, and the like.

Further, as shown in FIG. 1, the hair material 3 can be directly adhered to a large number of hair materials on the adhesive layer 4 without the linear member 31. Moreover, the said hair material 3 and the said linear member 31 can also be formed integrally.

In addition, as an application site, the above embodiment describes the case where the false eyelashes according to the present invention are attached to the upper eyelid, but it can also be attached to the lower eyelid.

The numerical values mentioned in the text regarding the size of each part of the base 1, hair material 3, etc. should be understood as an example. In particular, the thickness of the base 1 may be, for example, 30 μ, 40 μ, 50 μ, 60 μ, 70 μ, 80 μ, and 90 μ as long as the sheet is extremely thin. In addition, the length of the hair material 3 is not ask | required.

It is conceivable to use other high frequency waves such as ultrasonic waves as non-contact heat cutting means.

The adhesive constituting the adhesive layer 4 may be an adhesive that bonds strongly and instantaneously, and for example, an instantaneous adhesive mainly composed of cyanoacrylate may be used.

Regarding the supply of the adhesive to the base 1, when the adhesive is supplied without moving the base 1 as described in the above embodiment, the base 1 is cut on the work table 12 for each section and placed in large numbers. Alternatively, the adhesive may be supplied, or the long base 1 may be left on the work table 12 and cut into sections after the supply of the adhesive.

However, contrary to the above, it is conceivable to move the base 1 and supply an adhesive during the movement. In this case, when the base 1 is supplied in one direction, the supply pipe operates on the base 1, and when the base 1 moves, the supply pipe is turned on for a predetermined time to supply the adhesive linearly onto the base 1. .

The cutting of the connecting portion of each hair material 3 may be performed before application of the adhesive layer 4 or simultaneously with the supply of the adhesive.

The length of the cut line 11d of the size pattern scale 11 can be set to other sizes.

The invention of the present application can be used for manufacturing false eyelashes.
