Definitions
- the present invention relates to a false eyelash.
- the prior art false eyelash 103 comprises an extremely thin linear base 101 having approximately 0.5mm width and artificial eyelash transplanted onto the base, which is attached with bonding agent to an eyelid just above an eyelash 122.
- Another type prior art is, as shown in Fig.13 , adhered spottedly by using tweezers, for example, to a removed part of an eyelash 122 or to other reinforcing sites, at usually one or several points.
- 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.
- the prior art false eyelash is linear and, therefore, may be variously deformed when it is to be adhered. It may be deformed in a vertical direction, in a horizontal direction and in any directions in 360 degrees.
- the false eyelash should be adhered to the lower edge of an upper eyelid, which is difficult enough as it is.
- the linear false eyelash with full deformability should be adhered to such site. This makes it extremely difficult to fit the false eyelash in position, which requires high-level skill.
- the prior art false eyelash has a linear or spotly 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the base 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.
- 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.

- Fig.1 , Fig.2 and Fig.5 are schematic views, in which the number of the transplanted hair segments 3 is shown in a simplified manner.
- 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 Fig.5 .
- a base 1 for one section is supplied from long-length base material 1 M wound around a reel 13 to above a working position T on a workbench 12 ( Fig.6(A) ).
- the underside of the base material 1M is provided with a medical-grade adhesive agent that forms an adhesive layer 7 for fitting the base to a human body, which is backed with a release paper 9.
- a bonding agent that will form a bonding layer 4 is supplied to an appropriate position on the base 1 of a single section ( Fig.6(B) ). Although two bonding layers 4 are disposed along a horizontal direction in Fig.6(B) and Fig.6(D) , any number of the bonding layers may be mounted on the single-sectional base material 1 M to provide better yield. Supply of the bonding agent is carried out in such manner that it is supplied linearly by horizontally moving a supply pipe, not shown, above the base 1 firmly fixed to the workbench.
- 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 ( Fig.6(C) ).
- the cutting line L is shown by alternate long and short dash lines in Fig.6(C) ).
- 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 ( Fig.6(D) ). The robot shafts 15 are controlled to be in appropriate position, so that the hair segments 3 are adhered to the lower end portion 4a (shown in Fig.5(F)) of the bonding layer 4.
- the base 1 is cut by alternate long and short dash lines in Fig.6(D) ) which defines a single section.
- the base 1 is shipped after being cut by a laser beam R along the cutting line shown in Fig.7 into a predetermined shape. The cutting operation by which the base 1 is cut by the laser beam R will be described in reference to Fig. 10 .
- Fig.7 shows size pattern scales 11 for false eyelashes.
- Fig.7(A) shows scales for large-size eyes
- Fig.7(B) shows scales for medium-size eyes
- Fig.7(C) shows scales for partial fitting.
- a reference numeral 11A denotes the scale for a left eye
- a reference numeral 11 B denotes the scale for a right eye.
- the scale provides a straight-extending cutting line 11 d along which the base is cut to define the end portion 3b and cutting lines 11a, 11b, 11 c at the leading ends that are formed into a patternized convex arc shape in conformity to an upper curve 21 a of an eyeball 21 (shown in Fig.8(A) ).
- a cutting line 11 a is used for forming a double-edged or internally double-edged eyelid that is formed to have a size of 5mm at the maximum
- a cutting line 11 b is used for forming an internally double-edged or single-edged eyelid that is formed to have a size of 4-3mm at the maximum
- a cutting line 11c is used for forming a double-edged or single-edged eyelid that is formed to have a size of 2mm at the maximum.
- the cutting line 11d in Fig.7(A) is 30mm in length and the cutting line 11d in Fig.7(B) is 23mm in length, which may be cut to conform with the eye size.
- a cutting line 11a is used for forming a double-edged or multi-edged eyelid that is formed to have a size of 5mm at the maximum
- a cutting line 11 b is used for forming a double-edge or internally double-edged eyelid that is formed to have a size of 4-3mm at the maximum.
- the cutting line 11d is 15mm in length, which may be cut to conform with the size of a portion to which it is to be fitted.
- 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 Fig.1 and Fig.2 , whereas the other is shown as "1M" in Fig.5 , which is cut by the user.
- the former type may directly be fitted to the upper eyelid after removing the release paper 9.
- the latter type is first placed on a desired one of the size pattern scales 11 shown in Fig.7 with the hair segments 3 upward. Then, the cutting line depicted on the size pattern scale 11 is transcribed onto the base 1 by the user. Then, the base 1 is cut along the cutting line by the user. Then, the release paper 9 is removed, and the false eyelash is used by adhering the adhering surface onto the eyelid.
- the hair segment unit 3A is cut into the hair segments 3 by a laser beam, which will provide the following effects.
- 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.
- 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.
- 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.
- 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 Fig.8(A) through Fig.8(C) , so that the own eyelash 22 will appear from the enlarged gaps to be in alignment with the lines of the hair segments 3. Accordingly, there is the effect that the false eyelash fitted will be well in harmonization with the own hairs.
- 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.
- 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.
- 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.
- 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 Fig.9 . Deformation in other directions could be ignored in substance.
- the prior art base is deformable in all directions around 360 degrees.
- 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.
- the base 1 is formed into a three-dimensional shape that conforms to the curvature of the eyelid onto which the base is fitted, it will further improve good-fit and easy-fit to the upper eyelid 20.
- 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 Fig.8(A) through Fig.8(C) , the hair segment 3 is substantially aligned with the own eyelash 22 and, therefore, could not be distinguished from the own eyelash 22, which provides very good appearance. In addition, the remaining portion of the bonding layer 4 will not come into view, which provides good visibility.
- the root portion 5 of the hair segment 3 should be adhered to the center of the bonding layer 4, the own eyelash 22 and the hair segment 3 are vertically overlapped with each other to thereby greatly reduce appearance, and the remaining portion of the bonding layer 4 should come into view to thereby worsen the visibility as if it is in a fog. Such is prevented by the present invention.
- the laser beam R is irradiated from the underside of the base 1. If this cutting operation should be carried out such that, as shown by an alternate long and short dash line in Fig.10(A) , the laser beam R is irradiated at right angle to the base 1, especially just along the line to which the hair segment 3 is adhered, it would damage the hair segment 3 in most cases.
- the laser beam R should be irradiated at an angle of inclination with respect to the bonding layer 4 (for example, at an angle of 60 degrees inclined to the bonding layer 4) to cut the base 1, as shown by a solid line in Fig.10(A) .
- This manner of irradiation will prevent the hair segment 3 from being damaged adhered near to the bonding layer 4.
- whole or a part of the adhesive layer 7a formed on the underside of the base 1 would melt, so that it could separate or partly peel off from the underside. Under such conditions, even when it is fitted to the upper eyelid, the fittability to the upper eyelid should be lost, which reduce the fitting power.
- a part of the base 1 peels off from the upper eyelid, there is formed a gap between the base 1 and the upper eyelid, so that it really looks a false eyelash, which can easily be distinguished over the natural hair in appearance.
- a solid line in Fig.10(B) there is the space 2a on a site corresponding to the lower end portion 1c of the surface of the base 1 along the longitudinal direction, and the spaces 2b of equivalent size at the opposite ends of the bonding layer 4. Accordingly, even if the laser beam R is irradiated at a slant angle (for example, about 60 degrees to the base 1) to a site to be formed as the lower end portion 1c, it will not damage the hair segment 3.
- the output of the laser beam R may be small, which prevents melting of the adhesive layer 7 in the vicinity to the irradiated area. Accordingly, it prevents removal of the fitted false eyelash from the upper eyelid and separation of the hair segments 3 from the base 1.
- 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 Fig.8(A) through Fig.8(C) , the hair segment 3 is substantially aligned with the own eyelash 22 and, therefore, could not be distinguished from the own eyelash 22, which provides very good appearance. In addition, the remaining portion of the bonding layer 4 will not come into view, which provides good visibility. If the hair segment 3 should be adhered not just along with the lower edge of the base 1, the own eyelash 22 and the hair segment 3 are vertically overlapped with each other to thereby greatly reduce appearance, and the remaining portion of the bonding layer 4 should come into view to thereby worsen the visibility as if it is in a fog. Such is prevented by the present invention.
- cosmetic material drawing an eye linear may be applied to a small gap g (shown in Fig.8(C) ) formed between the space 2a and the own eyelash 22.
- the base 1 is formed planar, which is not processed for specific users, neither in two-dimensional or three-dimensional shape.
- the embodiment of Fig.5 of a type wherein it is cut by the user, the upper space 1 b (shown in Fig.5(A) ) of the adhered base 1 has a sufficient area for cutting, so that this can be used by cutting the leading end portion 1d of the base 1 to form a convex arc shape. This will provide the effect of lifting up the skin above the upper eyelid 20.
- 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.
- the base 1 is formed planar and the hair segments 3 are formed linearly along the lower end portion of the base 1
- 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.
- the eyelash that comprises the false one in fact
- 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 Fig.11 (A) and (B) , the same effect with those described above will be achieved.
- 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 Fig.11 (C) .
- the angle of inclination in this case is 45 degrees, for example, but may be appropriately determined depending upon the use's purpose, age, etc.
- a plurality of hair segment 3 may be directly adhered to the bonding layer 4, without use of linear member 31, as shown in Fig.1 .
- the hair segment 3 and the linear member 31 may be formed in one body.
- 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.
- 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.
- the base 1 is cut into several sections that are placed on the workbench 12, to which the bonding agent may be supplied.
- 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.
- the bonding agent is supplied to the moving base.
- 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.

Abstract
To provide a false eyelash that is easily wearable and prevented from slippage and separation while in use. It comprises an extremely thin base 1, a bonding layer 4 formed linearly on a surface of said base, a plurality of hair segments 3 individually and separately adhered to said bonding layer, and an adhesive layer 7 formed on an entire underside of said base, wherein said base is formed into substantially a two-dimensional configuration or a three-dimensional configuration that contours a curved shape of an eyelid to which said base is fitted. 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. 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. 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.
Description
- The present invention relates to a false eyelash.
- As shown in
Fig.12 , the prior artfalse eyelash 103 comprises an extremely thinlinear base 101 having approximately 0.5mm width and artificial eyelash transplanted onto the base, which is attached with bonding agent to an eyelid just above aneyelash 122. Another type prior art is, as shown inFig.13 , adhered spottedly by using tweezers, for example, to a removed part of aneyelash 122 or to other reinforcing sites, at usually one or several points. -
- Patent Document 1:
JP1974-044493A - 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
Fig.14 , the prior art false eyelash is linear and, therefore, may be variously deformed when it is to be adhered. It may be deformed in a vertical direction, in a horizontal direction and in any directions in 360 degrees. The false eyelash should be adhered to the lower edge of an upper eyelid, which is difficult enough as it is.
In addition, the linear false eyelash with full deformability should be adhered to such site. This makes it extremely difficult to fit the false eyelash in position, which requires high-level skill. - 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
spotly 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 toClaim 1 is further characterized in that the base is smaller than the eyelid.
The false eyelash according toClaim 1 orClaim 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 toClaim 1 orClaim 2 is further characterized in that the thickness of said base is equal to or smaller than 20 micrometers.
The false eyelash according toClaim 1 orClaim 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 toClaim 6 is further characterized in that said root portion is formed to have a sphere in cross-section.
The false eyelash according toClaim 7 is further characterized in that said hair segment is cut by a laser beam.
The false eyelash according toClaim 1 orClaim 2 is further characterized in that a root portion of said hair segment is formed into a planar shape.
The false eyelash according toClaim 9 is further characterized in that said hair segment is cut by a cutter.
The false eyelash according toClaim 1 orClaim 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 toClaim 11 is further characterized in that said hair segments are entwined with said linear members.
The false eyelash according toClaim 11 is further characterized in that said hair segments are bonded to said linear members.
The false eyelash according toClaim 12 orClaim 13 is further characterized in that said linear member(s) comprises a single one.
The false eyelash according toClaim 12 orClaim 13 is further characterized in that said linear member(s) comprises plural ones.
The false eyelash according toClaim 12 orClaim 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 ofClaim 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 ofClaim 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 ofClaim 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 ofClaim 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.

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.
- In
Fig.1 , areference numeral 1 denotes a base consisting of an extremely thin sheet. Its thickness is equivalent to a human skin (of the order of 20 micrometers, for example). Thebase 1 is made from elastic material such as polyurethane, tinged with a transparent light skin color and contoured into a three-dimensional configuration in conformity to a curved shape of an eyelid. Thebase 1 has aspace 2a on its surface, which extends along alower end portion 1c in a lengthwise direction, and also has abonding layer 4 on thelower end portion 1c, leaving thespace 2a. At the opposite ends of thebonding layer 4, there arespaces 2b of substantially equal size. Thebonding layer 4 comprises UV-curable agent and is formed linearly on the base 1 (shown inFig.6(B) ), to whichhair segments 3 are adhered. Areference numeral 1d denotes an upper end portion of thebase 1, which is formed into a convex arc. On the entire underside of thebase 1 is formed anadhesive layer 7 comprising a medical-grade adhesive agent for fitting to a human body. Theadhesive layer 7 comprises, for example, acrylic adhesive agent, which is formed with even thickness on the entire underside of thebase 1 by transfer process. More particularly, acrylic adhesive agent having release papers (PET) on the opposite sides thereof is prepared, and one of the release papers is separated from one side so that the said side is firmly fixed to the entire underside of thebase 1. For use, arelease paper 9 at the other side is separated, and then the base is adhered to an application site of an upper eyelid 20 (shown inFig.7(A)-(C) ).Reference numerals 3 denote hair segments that are individually and separately adhered to thebase 1, which comprises polyester fiber, for example. Thehair segment 3 is formed such that its leading end portion is curled upwardly. - A
root portion 5 of thehair segment 3 is formed into substantially a sphere, which is adhered to thebonding layer 4. The adhesion is carried out in such a manner that theroot portion 5 is positioned on thelower end portion 4a of thebonding layer 4, as shown inFig.1(C) . Its reason will be described later. - In the embodiment shown in
Fig.1 , thebase 1 is curved into a three-dimensional configuration, after being cut into a predetermined false eyelash shape, as described later. In this case, the length (f) of thebase end portion 1 c of the base 1 a might be greater than the length (i) of the eyelid 20 (shown inFig.8(A) ) between the inner corner and the tail of a human eye (f>i), equal to the latter (f=i) or smaller than the latter (f<i). As a result of experiment, it has been revealed that the case of (f>i) can provide the same effect as in the case of the embodiment shown inFig.2 , and more particularly will prevent separation of the false eyelash due to presence of thespaces base 1. This will be described later based onFig.10 . It has also been found that the case of (f=i) is preferable, because it will, in addition to achieving the above effect, prevent wrinkling of thebase end portion 1 c when fitted onto theupper eyelid 20, more effectively than in the embodiment ofFig.2 . It has also been found that the case of (f<i) is still more preferable, because it will, in addition to achieving the above effects, facilitate the fitting to theupper eyelid 20 and prevent wrinkling of thebase end portion 1 c more effectively, when compared with the embodiment shown inFig.2 . -
Fig.2 shows the second embodiment of a false eyelash according to the present invention. Abase 1 of this embodiment is formed substantially planar, not customized.Hair segments 3 are adhered to thebonding layer 4 in a state wherein they are connected with each other bylinear members 31. The structure excepting these points will be similar to the embodiment ofFig.1 . -
Fig.3 shows thebase 1 used in the false eyelash ofFig.2 . The spaces will be explained here. Thespaces base 1 in this embodiment has length L of about 26mm, considering that an average eye size i of a Japanese (shown inFig.8(A) ) is about 30mm. Its maximum width is about 2.6mm (W1) for a single-edged eyelid, and about 4mm (W2) for double-edged or internally double-edged eyelid. Thebase 1 may have various shapes depending upon the shape of an eyelid to which it is to be fitted, as described later based onFig.7 . Accordingly, the maximum width is represented generally as W inFig.3 . - The
hair segments 3 will be explained here. In this embodiment, theplural hair segments 3 are adhered individually and separately to thebonding layer 4 in such manner that they are connected with each other bylinear members 31. The above-described arrangement of thehair segments 3 may have various embodiments. For example,plural hair segments 3 may be entwined and combined with one or morelinear members 31. For example,Fig.4(a) and (B) show embodiments whereinplural hair segments 3 are incorporated into twolinear members bonding layer 4.Fig.4(C) and (D) show embodiments whereinplural hair segments 3 are clamped between two parallel-extendinglinear members bonding layer 4.Fig.4(E) and (F) show embodiments whereinplural hair segments 3 are bonded to a singlelinear member 31 by bonding agent and inserted, in this state, into the bonding component of thebonding layer 4.Fig.4(G) and (H) show embodiments whereinplural hair segments 3 are tied with a singlelinear member 31 and inserted, in this state, into the bonding component of thebonding layer 4. Thelinear member 31 may be thread, silk gut or the like. The length d of the hearsegment 3 is formed to be about 2-12mm. In most cases, the width e of thehair segment 3 to be adhered is 10-50mm. Eachhair segment 3 is curled upwardly even in ahair segment unit 3A shown inFig.4(A)-(H) . Thehair segments 3 at center are longer than those in other areas. - The embodiments of
Fig.1 andFig.2 will be shipped, after being cut in a factory to a predetermined shape of a false eyelash, whereas the third embodiment of the present invention shown inFig.5 is of a type wherein it is cut by the user. In this embodiment, thebase 1 is cut into arectangular shape 1 M that is larger than a predetermined false eyelash shape. For use, the user should cut by herself thebase 1 of the false eyelash along a cutting line shown inFig.7 . InFig.5(A) , a reference numeral 1a denotes the base after having been cut. The structure excepting these points will be similar to the embodiment ofFig.1 . - Regarding the size of various parts of the false eyelash shown in
Fig.5 , the vertical length of apre-use base 1 is about 20-30mm (a) for business use, and about 10-05mm (b) for personal use where it is cut near to thebase end portion 1 c. The lateral length (c) is about 10-40mm in common. The longitudinal size (d) of thehair segment 3 is about 2-12mm. Eachhair segment 3 is curled upwardly even in ahair segment unit 3A (shown inFig.6(C) ).Several hair segments 3 at center are longer than those in other areas. The width L (shown inFig.1(A) ), to which thehair segments 3 are adhered, is about 10-50mm. The base 1a in this embodiment has length L of about 26mm, considering that an average eye size i of a Japanese (shown inFig.8(A) ) is about 30mm. Its maximum width W is about 2.6mm for a single-edged eyelid, and about 4mm for double-edged or internally double-edged eyelid. Thebase 1 may have various shapes depending upon the shape of eyelid to which it is to be fitted, as described before based onFig.7 . -
Fig.1 ,Fig.2 andFig.5 are schematic views, in which the number of the transplantedhair segments 3 is shown in a simplified manner. - 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
Fig.5 . - A
base 1 for one section is supplied from long-length base material 1 M wound around areel 13 to above a working position T on a workbench 12 (Fig.6(A) ). The underside of thebase material 1M is provided with a medical-grade adhesive agent that forms anadhesive layer 7 for fitting the base to a human body, which is backed with arelease paper 9. - A bonding agent that will form a
bonding layer 4 is supplied to an appropriate position on thebase 1 of a single section (Fig.6(B) ). Although twobonding layers 4 are disposed along a horizontal direction inFig.6(B) and Fig.6(D) , any number of the bonding layers may be mounted on the single-sectional base material 1 M to provide better yield. Supply of the bonding agent is carried out in such manner that it is supplied linearly by horizontally moving a supply pipe, not shown, above thebase 1 firmly fixed to the workbench. - The
hair segment unit 3A comprising thehair segments 3 with theirend portions 3b being connected to each other are held by a pair ofrobot shafts 15 that can open and close. In this state, this is cut between theend portion 3b and therobot shafts 15 by a laser beam, not shown (Fig.6(C) ). The cutting line L is shown by alternate long and short dash lines inFig.6(C) ). - The hair segment will remain held by the
robot shafts 15, even after completing the cutting step. Still in this clamped state, therobot shafts 15 are lowered so that thecut hair segments 3 are adhered to the bonding agent (that forms "bonding layer 4") that has been supplied in the above-mentioned step (Fig.6(D) ). Therobot shafts 15 are controlled to be in appropriate position, so that thehair segments 3 are adhered to thelower end portion 4a (shown in Fig.5(F)) of thebonding layer 4. - Once the hair segments are adhered to the
base 1 in the above-described manner, thebase 1 is cut by alternate long and short dash lines inFig.6(D) ) which defines a single section. In the false eyelash shown inFig.2 , thebase 1 is shipped after being cut by a laser beam R along the cutting line shown inFig.7 into a predetermined shape. The cutting operation by which thebase 1 is cut by the laser beam R will be described in reference toFig. 10 . - 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. -
Fig.7 shows size pattern scales 11 for false eyelashes.Fig.7(A) shows scales for large-size eyes,Fig.7(B) shows scales for medium-size eyes andFig.7(C) shows scales for partial fitting. In these figures, areference numeral 11A denotes the scale for a left eye and areference numeral 11 B denotes the scale for a right eye. In these patterns, the scale provides a straight-extendingcutting line 11 d along which the base is cut to define theend portion 3b and cuttinglines upper curve 21 a of an eyeball 21 (shown inFig.8(A) ). - In
Fig.7(A) and (B) , a cuttingline 11 a is used for forming a double-edged or internally double-edged eyelid that is formed to have a size of 5mm at the maximum, a cuttingline 11 b is used for forming an internally double-edged or single-edged eyelid that is formed to have a size of 4-3mm at the maximum, and acutting line 11c is used for forming a double-edged or single-edged eyelid that is formed to have a size of 2mm at the maximum. Thecutting line 11d inFig.7(A) is 30mm in length and thecutting line 11d inFig.7(B) is 23mm in length, which may be cut to conform with the eye size. InFig.7(C) , acutting line 11a is used for forming a double-edged or multi-edged eyelid that is formed to have a size of 5mm at the maximum, and acutting line 11 b is used for forming a double-edge or internally double-edged eyelid that is formed to have a size of 4-3mm at the maximum. Thecutting line 11d is 15mm in length, which may be cut to conform with the size of a portion to which it is to be fitted. - 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
Fig.1 andFig.2 , whereas the other is shown as "1M" inFig.5 , which is cut by the user. The former type may directly be fitted to the upper eyelid after removing therelease paper 9. On the other hand, the latter type is first placed on a desired one of the size pattern scales 11 shown inFig.7 with thehair segments 3 upward. Then, the cutting line depicted on thesize pattern scale 11 is transcribed onto thebase 1 by the user. Then, thebase 1 is cut along the cutting line by the user. Then, therelease paper 9 is removed, and the false eyelash is used by adhering the adhering surface onto the eyelid. - In each of the above-described embodiments, the
hair segment unit 3A is cut into thehair segments 3 by a laser beam, which will provide the following effects. - Non-contact cutting by the laser beam will prevent the
hair segments 3 from unraveling and being scattered in various directions, when cut. Thehair segment unit 3A is cut by the laser beam while it remains held by therobot shafts 15, so that it may be cut at the connecting portion with the hair tips maintaining the original curled shape, to thereby separating thehair segments 3 from each other. Accordingly, thehair segments 3 remain in alignment. - The cutting by the laser beam will generate heat, so that the
root portion 5 at which eachhair segment 3 is cut will melt into a spherical shape. As a result, thisspherical 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 thebase 1. - Since the
root portion 5 of thehair segment 3 is formed into a spherical shape, any part of the spherical surface of theroot portion 5 may be adhered to thebonding layer 4. Thehair segments 3 may be firmly adhered to thebonding layer 4, while they remain held by therobot shafts 15, with the tips thereof maintaining the original curled orientation. Accordingly, in spite that therespective 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 thebase 1 while maintaining the original orientation of the hair tips, that is the curled shape thereof as it is. Accordingly, the underside of thebase 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. - Although the
hair segments 3 are adhered to thebase 1 while maintaining the upwardly curled shape and being separated from each other, once fitted to the eyelid, theupper eyelid 20 will open into a convex arcuate shape so that theroot portions 5 of thehair segments 3 adhered will also shaped into a convex arc along theupper eyelid 20. Consequently, thehair segments 3 that have originally been adhered in parallel will become angled radially, thereby enlarging the gaps formed between thehair segments 3. - The lines of the
hair segments 3 are adhered just above theown eyelash 22, as shown inFig.8(A) through Fig.8(C) , so that theown eyelash 22 will appear from the enlarged gaps to be in alignment with the lines of thehair segments 3. Accordingly, there is the effect that the false eyelash fitted will be well in harmonization with the own hairs. - Since the
root portion 5 of thehair segment 3 is formed into a spherical shape, any part of the spherical surface of theroot portion 5 may be adhered to thebonding layer 4. This makes it possible to adjust the angle of adhesion of thehair segments 3, which facilitate grouping of the products depending upon their use and extension of the products. For example, a product wherein thehair segments 3 are adhered to thebonding layer 4 in a crosswise manner will be suitable to the youth because the eyelash looks longer, whereas another produce wherein thehair segments 3 are adhered to thebonding 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 thebonding layer 4, which facilitates speedy and effective production. - 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, theplanar base 1 having the substantially straight-extendingbase end portion 1c and the convex arcuateleading end portion 1d will be deformed only in one direction (up-and-down direction), as shown inFig.9 . Deformation in other directions could be ignored in substance. In contrast, the prior art base is deformable in all directions around 360 degrees. - 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 thehair segments 3 along the lower edge of theupper 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 theupper eyelid 20, which prevent slippage and separation of the false eyelash while in use. When, as shown inFig.1 , thebase 1 is formed into a three-dimensional shape that conforms to the curvature of the eyelid onto which the base is fitted, it will further improve good-fit and easy-fit to theupper eyelid 20. - 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, thehair segments 3 in clamped condition are cutting linearly by the laser beam, so that theroot portions 5 of thehair segments 3 are formed into spherical shape, and any part of the spherical surface of theroot portion 5 may be adhered to thebonding layer 4. Accordingly, it may easily be adhered to theupper 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 theupper eyelid 20. Theroot portion 5 of thehair segment 3 is adhered to thelower end portion 4a of thebonding layer 4, which makes it possible to cut thebase 1 just along the adheredhair segment 3 with only asmall space 2a therebetween. Accordingly, as shown inFig.8(A) through Fig.8(C) , thehair segment 3 is substantially aligned with theown eyelash 22 and, therefore, could not be distinguished from theown eyelash 22, which provides very good appearance. In addition, the remaining portion of thebonding layer 4 will not come into view, which provides good visibility. If theroot portion 5 of thehair segment 3 should be adhered to the center of thebonding layer 4, theown eyelash 22 and thehair segment 3 are vertically overlapped with each other to thereby greatly reduce appearance, and the remaining portion of thebonding layer 4 should come into view to thereby worsen the visibility as if it is in a fog. Such is prevented by the present invention. - Let us talk about this in more detail. To cut the
base 1 into a predetermined shape shown inFig.1 andFig.2 , the laser beam R is irradiated from the underside of thebase 1. If this cutting operation should be carried out such that, as shown by an alternate long and short dash line inFig.10(A) , the laser beam R is irradiated at right angle to thebase 1, especially just along the line to which thehair segment 3 is adhered, it would damage thehair segment 3 in most cases. Accordingly, the laser beam R should be irradiated at an angle of inclination with respect to the bonding layer 4 (for example, at an angle of 60 degrees inclined to the bonding layer 4) to cut thebase 1, as shown by a solid line inFig.10(A) . This manner of irradiation will prevent thehair segment 3 from being damaged adhered near to thebonding layer 4. However, when the laser beam R is irradiated aslant, whole or a part of theadhesive layer 7a formed on the underside of thebase 1 would melt, so that it could separate or partly peel off from the underside. Under such conditions, even when it is fitted to the upper eyelid, the fittability to the upper eyelid should be lost, which reduce the fitting power. Moreover, when a part of thebase 1 peels off from the upper eyelid, there is formed a gap between thebase 1 and the upper eyelid, so that it really looks a false eyelash, which can easily be distinguished over the natural hair in appearance. - Moreover, when the laser beam R is irradiated in a slant angle to the
bonding layer 4, as shown by the solid line inFig.10(A) , it might damage a part of thebonding layer 4 adhering thehair segment 3, by which thehair segment 3 could be separated from thebase 1. - In accordance with this embodiment, as shown by a solid line in
Fig.10(B) , there is thespace 2a on a site corresponding to thelower end portion 1c of the surface of thebase 1 along the longitudinal direction, and thespaces 2b of equivalent size at the opposite ends of thebonding layer 4. Accordingly, even if the laser beam R is irradiated at a slant angle (for example, about 60 degrees to the base 1) to a site to be formed as thelower end portion 1c, it will not damage thehair segment 3. The output of the laser beam R may be small, which prevents melting of theadhesive layer 7 in the vicinity to the irradiated area. Accordingly, it prevents removal of the fitted false eyelash from the upper eyelid and separation of thehair segments 3 from thebase 1. - The
hair segments 3 are adhered to thebase 1 just along the lower edge thereof, leaving thesmall space 2a that is hardly be recognized by the naked eyes. Accordingly, as shown inFig.8(A) through Fig.8(C) , thehair segment 3 is substantially aligned with theown eyelash 22 and, therefore, could not be distinguished from theown eyelash 22, which provides very good appearance. In addition, the remaining portion of thebonding layer 4 will not come into view, which provides good visibility. If thehair segment 3 should be adhered not just along with the lower edge of thebase 1, theown eyelash 22 and thehair segment 3 are vertically overlapped with each other to thereby greatly reduce appearance, and the remaining portion of thebonding layer 4 should come into view to thereby worsen the visibility as if it is in a fog. Such is prevented by the present invention. - In addition, there also remain the
spaces 2b at the opposite ends of thebase 1, to which nohair segment 3 is adhered, so that the receding hairline of theown eyelash 22 is conformable with the adhesion site of thehair 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
Fig.8(C) ) formed between thespace 2a and theown eyelash 22. - In the embodiments shown in
Fig.2 andFig.5 , thebase 1 is formed planar, which is not processed for specific users, neither in two-dimensional or three-dimensional shape. The embodiment ofFig.5 of a type wherein it is cut by the user, the upper space 1 b (shown inFig.5(A) ) of the adheredbase 1 has a sufficient area for cutting, so that this can be used by cutting theleading end portion 1d of thebase 1 to form a convex arc shape. This will provide the effect of lifting up the skin above theupper eyelid 20. - 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 theupper eyelid 20, lift up theupper 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 thehair segments 3 are formed linearly along the lower end portion of thebase 1, when thebase 1 is adhered to theupper eyelid 20, thebase 1 is deformed in a convex arc shape in alignment with theupper lid 20 that has a convex arc shape, so that therespective 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 thehair 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 inFig.11 (A) and (B) , the same effect with those described above will be achieved. - The
root portion 5 of thehair segment 3 is adhered perpendicular in the preceding embodiments shown in the drawings, but may extend aslant downwardly, as shown inFig.11 (C) . The angle of inclination in this case is 45 degrees, for example, but may be appropriately determined depending upon the use's purpose, age, etc. - A plurality of
hair segment 3 may be directly adhered to thebonding layer 4, without use oflinear member 31, as shown inFig.1 . Thehair segment 3 and thelinear member 31 may be formed in one body. - 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, thehair segment 3 and the like are described merely as examples. Especially, thebase 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 thehair 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 thebase 1 that remains stationary, as described in connection with the preceding embodiments, thebase 1 is cut into several sections that are placed on theworkbench 12, to which the bonding agent may be supplied. In another embodiment, the longcontinuous base 1 is placed on theworkbench 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 thebase 1 is moved in one direction, which is turned on for a predetermined time during movement of thebase 1, to thereby supply the bonding agent linearly to thebase 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 thesize pattern scale 11 may be changed to different size. - The present invention is applicable to a false eyelash.
