The present invention relates to a false eyelash.
As shown in
Patent Document 1: JP1974-044493A(U)
Patent Document 2: JP2008-231632A
The prior arts use bonding agent for adhesion of false eyelash, which has the risk that the eye could be damaged. Accordingly, the false eyelash adhering operation should be done with case, which requires prudent attention and take a long time. In some case, the false eyelash is used even though not sufficiently adhered.
This will result from the following reasons. As shown in
Even if it is once adhered successfully, it is adhered linearly or spottily only in an extremely small area so that it could be slipped off due to up-and-down movement of the eyelid while in use, which greatly spoils appearance.
The prior art false eyelash has a linear or spotty base 101 providing a small area for adhesion, which makes it impossible to wear the false eyelash for a long period of time. It could be detached or slipped off by face-washing.
Moreover, the prior art requires use of solvent-containing bonding agent, when it is to be fitted to the eyelid or while in use, so that a wearer cannot open her eyes for a predetermined time after the false eyelash is adhered, because solvent will volatilize.
Furthermore, the linear base, especially its opposite end portions may hit against the eyelid, which causes pain to a wearer. Because of the linear body to be attached, it lasts only six hours around at the longest. It would easily be removed by face-washing or tears.
To cope with these problems, the present inventors have offered Patent Document 2, which, however, still have the following defects.
The false eyelash of Patent Document 2 utilizes a base that has been developed for a hair-transplanted wig with a rugged underside. When such base is fitted onto a head, ruggedness on the underside will turn the other way around. Such inversion of ruggedness on the underside can be expected because the wig has relatively wide area for fitting. This, however, is not practically applicable to a false eyelash to be fitted to an eyelid. This is because why an eyelid is one of the thinnest human skin sites, usually having thickness of the order of 10-20 micrometers, which could not bear a great value of pressure applicable to a head when a wig is to be fitted.
Accordingly, an adhesive layer only on the convex of the base underside is adhered to the eyelid, but the adhesive layer on the concave is very hard to be adhered to the eyelid.
As a consequence, a gap is formed between the concave and the eyelid to lower the fitting power and also lower the fitting period, by which the false eyelash once adhered could be easy to be removed due to water flooded into the concave during face-washing or by tears.
The object of the present invention is to eliminate the above-described defects, more particularly to provide a false eyelash that is easily wearable with hair segments being aligned in good order and is prevented from slippage and separation while in use. Other objects will become apparent from the following description.
To achieve the above-described objects, a false eyelash according to the present invention is characterized in that it comprises an extremely thin base, a bonding layer formed linearly on a surface of the base, a plurality of hair segments individually and separately adhered to the bonding layer, and an adhesive layer formed on an entire underside of the base, said base being formed into a three-dimensional configuration that contours a curved shape of an eyelid to which the base is fitted.
In another aspect, the false eyelash according to the present invention is characterized in that it comprises an extremely thin base, a bonding layer formed linearly on a surface of the base, a plurality of hair segments individually and separately adhered to the bonding layer, and an adhesive layer formed on an entire underside of the base, said base being formed into substantially a two-dimensional shape.
The false eyelash according to Claim 1 is further characterized in that the base is smaller than the eyelid.
The false eyelash according to Claim 1 or Claim 2 is further characterized in that a base end portion of said base is cutting linearly, and its end portion opposite to said base end portion is cut into a convex arc shape.
The false eyelash according to Claim 1 or Claim 2 is further characterized in that the thickness of said base is equal to or smaller than 20 micrometers.
The false eyelash according to Claim 1 or Claim 2 is further characterized in that a root portion of said hair segment is formed to have a curved shape in cross-section.
The false eyelash according to Claim 6 is further characterized in that said root portion is formed to have a sphere in cross-section.
The false eyelash according to Claim 7 is further characterized in that said hair segment is cut by a laser beam.
The false eyelash according to Claim 1 or Claim 2 is further characterized in that a root portion of said hair segment is formed into a planar shape.
The false eyelash according to Claim 9 is further characterized in that said hair segment is cut by a cutter.
The false eyelash according to Claim 1 or Claim 2 is further characterized in that said hair segments are adhered to said bonding layer while they are connected and aligned with each other by one or more linear members.
The false eyelash according to Claim 11 is further characterized in that said hair segments are entwined with said linear members.
The false eyelash according to Claim 11 is further characterized in that said hair segments are bonded to said linear members.
The false eyelash according to Claim 12 or Claim 13 is further characterized in that said linear member(s) comprises a single one.
The false eyelash according to Claim 12 or Claim 13 is further characterized in that said linear member(s) comprises plural ones.
The false eyelash according to Claim 12 or Claim 13 is further characterized in that said linear member(s) and said hair segments are formed in one body.
The false eyelash according to any one of Claim 6 to Claim 16 is further characterized in that said hair segments are adhered to a lower end portion of said bonding layer.
The false eyelash according to any one of Claim 6 to Claim 17 is further characterized in that said root portion of said hair segment is adhered perpendicularly to said bonding layer.
The false eyelash according to any one of Claim 6 to Claim 17 is further characterized in that said root portion of said hair segment is adhered aslant to said bonding layer.
The false eyelash according to any one of Claim 6 to Claim 17 is further characterized in that a leading end portion of said hair segment is curled outwardly in relation to a base end portion of said base.
In the false eyelash according to the present invention, since the base is formed into a three-dimensional configuration that contours a curved shape of the eyelid, it may be fitted tightly to the eyelid. Even when the base is formed into substantially a two-dimensional configuration, the base is extremely thin and, therefore, can be fitted tightly to the eyelid along the curved shape of the eyelid. At this time, the hair segments are firmly adhered to the bonding layer in such manner that they remain linearly attached to the base, by which the false eyelash with the hair segments being kept in well aligned state can easily be fitted to the eyelid.
Further, when it is fitted to the eyelid, because the hair segments are linearly attached to the lower end portion of the base, it can be fitted in such manner that the hair segments are substantially aligned with the own eyelash. Accordingly, the false eyelash could not be distinguished from the own eyelash, providing very good appearance. In addition, the remaining portion of the bonding layer is not visible, providing good visibility.
The false eyelash according to the present invention provides a planar, wide area for adhesion, and said wide adhesive area is adhered to an upper eyelid, for example. Accordingly, in addition to the fact that the surfaces of the base held by the user are wide, planar, easily-handled surfaces, it is very easy to position the base end portion to align with the lower edge of the upper eyelid when fitting the false eyelash, thereby greatly saving labor and time required for the fitting operation. Further, the adhesive surface is planar and has a wide area for adhesion to the eyelid, which prevent slippage and separation of the false eyelash while in use.
Next, the false eyelash according to the present invention will be described in more detail based on the drawings that illustrate embodiments thereof. As a matter of convenience, any part having the same facility will be represented by the same reference numeral and their explanation will be omitted.

A root portion 5 of the hair segment 3 is formed into substantially a sphere, which is adhered to the bonding layer 4. The adhesion is carried out in such a manner that the root portion 5 is positioned on the lower end portion 4a of the bonding layer 4, as shown in
In the embodiment shown in
The hair segments 3 will be explained here. In this embodiment, the plural hair segments 3 are adhered individually and separately to the bonding layer 4 in such manner that they are connected with each other by linear members 31. The above-described arrangement of the hair segments 3 may have various embodiments. For example, plural hair segments 3 may be entwined and combined with one or more linear members 31. For example,
The embodiments of
Regarding the size of various parts of the false eyelash shown in
<Manufacturing Process>
The false eyelash according to the present invention is, for example, manufactured by the following process. The process will be explained for manufacturing the false eyelash shown in
First Step (Base Supplying Step)
A base 1 for one section is supplied from long-length base material 1M wound around a reel 13 to above a working position T on a workbench 12 (
Second Step (Bonding Agent Supplying Step)
A bonding agent that will form a bonding layer 4 is supplied to an appropriate position on the base 1 of a single section (
Third Step (Hair Segment Cutting Step)
The hair segment unit 3A comprising the hair segments 3 with their end portions 3b being connected to each other are held by a pair of robot shafts 15 that can open and close. In this state, this is cut between the end portion 3b and the robot shafts 15 by a laser beam, not shown (
Fourth Step (Hair Segment Adhering Step)
The hair segment will remain held by the robot shafts 15, even after completing the cutting step. Still in this clamped state, the robot shafts 15 are lowered so that the cut hair segments 3 are adhered to the bonding agent (that forms “bonding layer 4”) that has been supplied in the above-mentioned step (
Fifth Step (Productization Step)
Once the hair segments are adhered to the base 1 in the above-described manner, the base 1 is cut by alternate long and short dash lines in
Then, the next single section of the base 1 is supplied onto the working position T and the above-described operation is practiced. Such operation will be repeated continuously.

<Usage>
The false eyelash according to the present invention has two types. One is productized in a state wherein it has been cut into a predetermined shape shown in
<Cutting Effect by Laser Beam>
In each of the above-described embodiments, the hair segment unit 3A is cut into the hair segments 3 by a laser beam, which will provide the following effects.
(1) Non-Contact Cutting
Non-contact cutting by the laser beam will prevent the hair segments 3 from unraveling and being scattered in various directions, when cut. The hair segment unit 3A is cut by the laser beam while it remains held by the robot shafts 15, so that it may be cut at the connecting portion with the hair tips maintaining the original curled shape, to thereby separating the hair segments 3 from each other. Accordingly, the hair segments 3 remain in alignment.
(2) Cutting with Heating
The cutting by the laser beam will generate heat, so that the root portion 5 at which each hair segment 3 is cut will melt into a spherical shape. As a result, this spherical root portion 5 may be used as a tab for adhesion, which will make it unnecessary to have a separate step for providing a tab for adhesion to the base 1.
Since the root portion 5 of the hair segment 3 is formed into a spherical shape, any part of the spherical surface of the root portion 5 may be adhered to the bonding layer 4. The hair segments 3 may be firmly adhered to the bonding layer 4, while they remain held by the robot shafts 15, with the tips thereof maintaining the original curled orientation. Accordingly, in spite that the respective hair segments 3 are adhered spottedly, the hair tips will not scatter in various directions, which makes it possible that the hair segments are fixed to the surface of the base 1 while maintaining the original orientation of the hair tips, that is the curled shape thereof as it is. Accordingly, the underside of the base 1 do not have an uneven surface, which was required in the prior arts, thereby preventing entry of water, etc. while in use and preventing displacement and separation of the false eyelash.
(3) Effect of Enlargement of Eyelid, Effect of Harmonization with Own Hairs
Although the hair segments 3 are adhered to the base 1 while maintaining the upwardly curled shape and being separated from each other, once fitted to the eyelid, the upper eyelid 20 will open into a convex arcuate shape so that the root portions 5 of the hair segments 3 adhered will also shaped into a convex arc along the upper eyelid 20. Consequently, the hair segments 3 that have originally been adhered in parallel will become angled radially, thereby enlarging the gaps formed between the hair segments 3.
The lines of the hair segments 3 are adhered just above the own eyelash 22, as shown in
(4) Effect of Spherically Forming Root Portion of Hair Segment 3
Since the root portion 5 of the hair segment 3 is formed into a spherical shape, any part of the spherical surface of the root portion 5 may be adhered to the bonding layer 4. This makes it possible to adjust the angle of adhesion of the hair segments 3, which facilitate grouping of the products depending upon their use and extension of the products. For example, a product wherein the hair segments 3 are adhered to the bonding layer 4 in a crosswise manner will be suitable to the youth because the eyelash looks longer, whereas another produce wherein the hair segments 3 are adhered to the bonding layer 4 in an oblique manner will be suitable to the aged because the eyelash looks thicker.
In addition, any part of the spherical surface of the root portion 5 may be adhered to the bonding layer 4, which facilitates speedy and effective production.
<Other Effects>
The above-described embodiments will further provide the following effects.
The false eyelash according to the present invention has a wide, planar adhesive surface, and this wide adhesive surface is adhered to the upper eyelid 20. When adhered, the planar base 1 having the substantially straight-extending base end portion 1c and the convex arcuate leading end portion 1d will be deformed only in one direction (up-and-down direction), as shown in
Accordingly, in addition to the fact that the surfaces of the base 1 held by the user are wide, planar, easily-handled surfaces, it is very easy to position the hair segments 3 along the lower edge of the upper eyelid 20 when fitting the false eyelash, thereby greatly saving labor and time required for the fitting operation. Further, the adhesive surface is planar and has a wide area for adhesion to the upper eyelid 20, which prevent slippage and separation of the false eyelash while in use. When, as shown in
The good-fit and easy-fit to the upper eyelid 20 will be described in more detail in relation to the above-described cutting effect by the laser beam. First, the hair segments 3 in clamped condition are cutting linearly by the laser beam, so that the root portions 5 of the hair segments 3 are formed into spherical shape, and any part of the spherical surface of the root portion 5 may be adhered to the bonding layer 4. Accordingly, it may easily be adhered to the upper eyelid 20 while remaining the orientation of the curled hair tips.
The base 1 is adhered along the own hair extending from the lower edge of the upper eyelid 20. The root portion 5 of the hair segment 3 is adhered to the lower end portion 4a of the bonding layer 4, which makes it possible to cut the base 1 just along the adhered hair segment 3 with only a small space 2a therebetween. Accordingly, as shown in
Let us talk about this in more detail. To cut the base 1 into a predetermined shape shown in
Moreover, when the laser beam R is irradiated in a slant angle to the bonding layer 4, as shown by the solid line in
In accordance with this embodiment, as shown by a solid line in
The hair segments 3 are adhered to the base 1 just along the lower edge thereof, leaving the small space 2a that is hardly be recognized by the naked eyes. Accordingly, as shown in
In addition, there also remain the spaces 2b at the opposite ends of the base 1, to which no hair segment 3 is adhered, so that the receding hairline of the own eyelash 22 is conformable with the adhesion site of the hair segments 3. This will provide an effect such that the false eyelash thus produced looks more naturally.
Furthermore, cosmetic material drawing an eye linear may be applied to a small gap g (shown in
In the embodiments shown in
The skin above the upper eyelid 20 will deteriorate with time and become flabby little by little, but this lift-up effect makes it possible to adjust an area to be cut depending upon the flabby state of the skin above the upper eyelid 20, lift up the upper eyelid 20 and thereby providing an appearance of a bright pair of eyes, which is so-called anti-aging effect.
Furthermore, in the embodiment wherein the base 1 is formed planar and the hair segments 3 are formed linearly along the lower end portion of the base 1, when the base 1 is adhered to the upper eyelid 20, the base 1 is deformed in a convex arc shape in alignment with the upper lid 20 that has a convex arc shape, so that the respective hair segments 3, which are adhered separately and individually, are enlarged radially. As a result, the eyelash (that comprises the false one in fact) provides a thick line, thereby providing an appearance of a bright pair of eyes.
The false eyelash according to the present invention is not limited to the above-identified embodiments. For example, the root portion 5 of the hair segment 3 may be of any curved shape (an arc shape in cross-section, for example) other than sphere. When it is cut flat, as shown in
The root portion 5 of the hair segment 3 is adhered perpendicular in the preceding embodiments shown in the drawings, but may extend aslant downwardly, as shown in
A plurality of hair segment 3 may be directly adhered to the bonding layer 4, without use of linear member 31, as shown in
Regarding the site of application, the false eyelash according to the present invention is adhered to the upper eyelid in the above-identified embodiments, but it may be adhered to the lower eyelid.
It is to be understood that numeral values indicating the size of various portions of the base 1, the hair segment 3 and the like are described merely as examples. Especially, the base 1 may have various thickness, including, for example, 30 micrometers, 40 micrometers, 50 micrometers, 60 micrometers, 70 micrometers, 80 micrometers and 90 micrometers, as far as it can be called an extremely thin sheet. The length of the hair segment 3 is not limitative.
Non-contact cutting means with heat may alternatively be carried out by using high frequency such as ultrasonic waves.
The bonding agent forming the bonding layer 4 may be any one, as far as it provides instant, firm bonding capability, which may be an instantaneous bonding agent including cyanoacrylate as a main ingredient.
Regarding supply of the bonding agent to the base 1, when the bonding agent is supplied to the base 1 that remains stationary, as described in connection with the preceding embodiments, the base 1 is cut into several sections that are placed on the workbench 12, to which the bonding agent may be supplied. In another embodiment, the long continuous base 1 is placed on the workbench 12, to which the bonding agent is supplied, and then the base is cut into several sections.
On the contrary, it can be imagined that the bonding agent is supplied to the moving base. In this case, the supply pipe is moved onto the base 1 while the base 1 is moved in one direction, which is turned on for a predetermined time during movement of the base 1, to thereby supply the bonding agent linearly to the base 1.
The cutting of the hair segments at the connecting portion may be done before application of the bonding layer 4 or at the same time of supplying the bonding agent.
The length of the cutting line 11d in the size pattern scale 11 may be changed to different size.
The present invention is applicable to a false eyelash.
