Description

  The present invention relates to false eyelashes.

  As shown in FIG. 8, the conventional false eyelashes 103 have artificial eyelashes planted on a very thin linear base 101 having a width of about 0.5 mm, and are adhered to the eyelids just above the eyelashes 122 with an adhesive. Further, as shown in FIG. 9, there is a type in which the eyelashes 122 are dropped and attached to the other reinforcing portions in a dotted manner using tweezers or the like at a level of usually one to several places.

  Conventionally, since an adhesive is used for sticking, there is a risk that if one step is wrong, the eyes may 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. 10, 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.

  Even when the sticking was successful, the sticking area was very small, such as a line or a dot, so that it could be displaced by the vertical movement of the lid during mounting.

  Conventional false 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 face may fall off or shift due to face washing.

  Furthermore, since an adhesive containing a solvent is used, the eye cannot be opened for a certain period of time due to the volatilization of the solvent after mounting.

  Furthermore, when wearing the eyelid or during wearing, particularly both ends of the wire 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 has proposed Patent Document 2, which still has 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.

  For this reason, only the adhesive layer attached to the convex part on the back surface of the base is attached to the eyelid, and the adhesive layer attached to the concave part is very difficult to attach to the eyelid.

  As a result, a gap is formed between the concave portion and the eyelid, so that the mounting force is reduced and the duration of the mounting is also reduced, and there is a possibility that moisture may 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, and more specifically, to provide false eyelashes that can be easily attached while keeping the hair materials arranged in an orderly manner and that do not deviate or become detached during attachment. Other purposes will be made clear from the following description.

In order to achieve the above object, the false eyelashes according to the present invention comprise an ultra-thin base formed in a substantially two-dimensional shape, an adhesive layer formed linearly on the surface of the base, and a separate state in the adhesive layer It is characterized by comprising a plurality of hair materials pasted in and an adhesive layer formed on the entire back surface of the base, and the base of the hair material is formed in a spherical shape.
The false eyelashes according to claim 1 are characterized in that the hair material is cut by laser light.
The false eyelashes according to claim 1 or 2, wherein the hair material is attached to a lower end portion of the adhesive layer.
In addition, the false eyelashes according to any one of claims 1 to 3, wherein a base portion of the hair material is stuck to the adhesive layer in an orthogonal shape.
In addition, the false eyelashes according to any one of claims 1 to 3, wherein a base part of the hair material is attached to the adhesive layer in an inclined manner.
The false eyelashes according to claim 1 are characterized in that the hair material is curled toward the upper end.
The false eyelashes according to claim 1 are characterized in that the lower end of the base is cut into a straight line and the upper end is cut into a projecting arc.
The false eyelashes according to claim 1 are characterized in that the thickness of the upper base is 20 μm or less.

In the false eyelashes according to the present invention, the hair material is cut by a non-contact heat cutting means, so the hair material is cut linearly and the base of the hair material is formed in a spherical shape. As a result, the curled hair tips can be firmly attached to the adhesive layer of the base with the directionality thereof aligned. Therefore, it is possible to easily attach false eyelashes to the eyelids in a state where the hair materials are orderly arranged.
In addition, since the hair material is formed in a straight line when wearing, the eyelashes of the own hair and the false eyelashes can be worn so as to overlap substantially on the same line, so that the false eyelashes can be distinguished from the own hair. This is not possible, so the appearance is very good. Moreover, since the remainder of the adhesive layer does not enter the field of view, the field of view is improved.
The false eyelashes according to the present invention have a sticking surface that is wide in a planar shape, and this wide sticking surface is stuck on the upper eyelid. Therefore, when attaching false eyelashes, positioning of the base end to the upper and lower edges of the upper eyelid is very easy, coupled with the fact that the surface of the base to be handled is a wide and easy-to-handle surface, greatly reducing the labor and time of the mounting work. Can save you money. Moreover, since the sticking surface is planar and the area to be stuck on the upper eyelid is large, there is no possibility that the false eyelashes will be displaced or detached during wearing.

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

  1 to 5, reference numeral 1 denotes a base, and 1a denotes a base after separation. Each of the bases is made of a very thin sheet (for example, 20 μm thick) about the human skin. Hereinafter, the term “base 1” includes the base 1a after separation unless otherwise specified. The base 1 is made of a stretchable, colorless and transparent material such as polyurethane, and is formed in a substantially flat shape. 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 front end portion 6 upward. 3b (shown in FIG. 4C) is a base end portion of the hair material 3. Reference numeral 4 denotes an adhesive layer made of a UV curing agent (shown in FIG. 4B), which is formed linearly on the base 1.

  The base 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.

  Reference numeral 7 denotes an adhesive layer, which is formed on the entire back surface of the base 1 with a uniform thickness. The adhesive layer 7 is made of, for example, an acrylic adhesive and is formed 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 FIG. 6).

  FIG. 5 shows a false eyelash size pattern scale 11. FIG. 5A shows a scale used when the eye size is large, FIG. 5B shows the same size, and FIG. 5C shows a scale used for partial wearing. 11B represents the right eye. In each pattern, the cut line 11d cut along the base end 3b is formed in a straight line, and the cut lines 11a, 11b, and 11c at the distal end are matched with the upper curve 21a (shown in FIG. 6) of the eyeball 21. It is formed into a patterned salient curve. Reference numeral 22 denotes eyelashes of the human body (shown in FIGS. 6A and 6B). FIG. 1A shows a base 1 separated along the size pattern scale 11 as “1a”. Reference numeral 2 denotes an affixing surface of the separated base 1a. In addition, FIG. 1 is a schematic diagram, and the number of planted hair materials 3 shown in FIGS. 1 (A) to 1 (E) is simplified.

Although the length of the cut line 11d in FIG. 5A is 30 mm and the length of the cut line 11d in FIG. 5B is 23 mm, it can be appropriately cut according to the size of the eyes. In FIG. 5 (C), “11a” is a cut line for forming a double or double duplex formed at a maximum of 5 mm, and “11b” is a double or deep duplex formed at a maximum of 4 mm 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.

  Here, the size of each part will be explained. As for the vertical size of the base 1 before use, the business size a is about 20 mm to about 30 mm, and the personal size b cut to the vicinity of the base end 3 b is about 10 mm to about 15 mm. The horizontal size c is formed to be approximately 10 mm to 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. 4C), and several hairs near the center are formed longer than the other parts. The width e to which the hair material 3 is attached is about 10 mm to 30 mm.

<Manufacturing process>
The false eyelashes according to the present invention are manufactured by the following steps.

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. 4A). 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)
The adhesive which becomes the contact bonding layer 4 is supplied to the appropriate position (center part) of the base 1 for said 1 division (FIG. 4 (B)). 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. 4C). The cut line L is shown with a dashed-dotted line in FIG.

Fourth step (hair material sticking step)
Even after the cutting is completed, the hair material is continuously gripped by the robot shaft 15, and the hair material cut into the adhesive applied in the above-described step (this forms the "adhesion layer 7") in the gripped state. Is attached by lowering the robot shaft 15 (FIG. 4D). The hair material 3 is attached to the lower end of the adhesive layer 7 as shown in FIG. 2 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 base 1 for one section indicated by a one-dot oblique line M in FIG. 4D is cut by a cutter (not shown) to obtain a product.

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

<Usage>
Next, a method for using false eyelashes according to the present invention will be described. First, the base 1 is placed on the desired size pattern scale 11 shown in FIG. 5 with the hair material 3 facing up. 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 2 is stuck on the eyelid.

<Laser cutting effect>
In the present embodiment, since the hair material 3 is cut out from the hair material unit 3A by the laser beam and taken out, the following effects are obtained.

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 cutting with laser light generates heat at the time of cutting, the root part 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.

  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, intrusion of moisture or the like during wearing is prevented, so that the false eyelashes are prevented from shifting or coming off.

The effect of spreading the eyelids and the effect of being united with the own hair Each hair material 3 is adhered to the base 1 in a separated state while maintaining the curled state upward, but when attached to the eyelids, As will be described later, since the upper collar 20 is opened in a projecting shape, the 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.

  As shown in FIG. 6, the line of each hair material 3 is attached immediately above the own hair lashes 22, so that the own hair lashes 22 protrude from this widened gap and are the same line as the line of each hair material 3. Become up. 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, and if the hair material 3 is attached to the adhesive layer 4 while being inclined, the amount of eyelashes is increased. For elderly people.

  In addition, since any portion of the spherical surface of the root portion 5 can be adhered to the adhesive layer 4, a quick and efficient production is possible.

<Other effects>
In the present embodiment, the following effects are further obtained.

  In the false eyelashes according to the present invention, the sticking surface 2 is configured to be wide in a planar shape, and the wide sticking surface 2 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 °. While it is deformed, it is only in one direction (vertical direction), and other deformations can be substantially ignored.

  Therefore, when attaching false eyelashes, the positioning of the hair material base end portion 3b to the lower edge of the upper eyelid 20 is very easy in combination with the fact that the surface of the base 1 to be handled is a wide and easy-to-handle surface. It can save a lot of time and effort. Moreover, since the sticking surface 2 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 wearing.

  Here, the goodness of attachment to the upper collar 20 and the ease of attachment 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, since the base part 5 of the base material 1 is attached to the lower end part of the adhesive layer 4 when the base 1 is attached along the own hair of the lower edge of the upper collar 20, the attached hair material 3 is attached. It is possible to cut the base 1 along the line. For this reason, since the eyelashes 22 of the own hair and the hair material 3 overlap substantially on the same line as shown in FIGS. 6 (A) and 6 (B), they cannot be distinguished from the own hair, 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 hair 22 and the hair material 3 are doubled up and down, but the appearance of the hair layer 3 is not good. Since the remainder of 4 enters the field of view, the field of view becomes foggy and worsens, but this is prevented.

  Furthermore, the base 1 is formed in a planar shape and is not processed for a specific user in two dimensions or three dimensions. Moreover, since the upper space 1b (shown in FIG. 1 (A)) of the attached base 1 has a sufficient area so that it can be freely cut, the tip 1d of the base 1 is cut into a projecting shape. can do. 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, since the hair material 3 is formed in a straight line shape, when the base 1 is affixed to the upper collar 20, the base portion 5 becomes a projecting shape along the projecting upper collar 20. Each attached hair material 3 is spread radially. For this reason, the line of eyelashes (actually "false eyelashes") looks dark and the eyes look very large.

  The false eyelashes according to the present invention are not limited to the above-described embodiments. For example, the sticking angle of the root portion 5 of each hair material 3 is not orthogonal as shown in FIG. 2 (A), but can be inclined downward as shown in FIG. 2 (B). 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.

  In addition, it is conceivable to use a high frequency wave such as an ultrasonic wave as the non-contact heat cutting means.

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

  The numerical values described in the text regarding the sizes of the base 1 and the hair material 3 should be understood as examples.

  Regarding the supply of the adhesive to the base 1, when supplying the adhesive 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 divided into a large number. 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 adhesive is supplied.

  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 connection part of each hair material 3 may be cut 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 present invention can be used as false eyelashes.
