Description
本発明は、新規な付けまつ毛及び付けまつ毛用貼着シートに関する。 The present invention relates to a novel false eyelash and an adhesive sheet for false eyelash.
付けまつ毛は、美容等の分野において欠かせないアイテムとなっているが、ユーザーの嗜好の多様化に伴って様々なタイプの付けまつ毛が開発されている。ところが、従前の付けまつ毛は、糸状ベースにまつ毛が接着された構成であるため、その装着に熟練を要するものであったり、あるいは装着した後に発汗等によって位置ずれ、傾き等が生じたりという問題がある。 Although false eyelashes are an indispensable item in the field of beauty and the like, various types of false eyelashes have been developed with diversifying user preferences. However, since the conventional false eyelashes have a configuration in which the eyelashes are bonded to the thread base, there is a problem that the wearing requires skill, or that there is a problem of positional displacement, inclination, etc. due to sweating after wearing. is there.
これらの問題を改善するために、例えばまぶたに貼り付けることのできるフィルムにまつ毛がフィルム表面に突出して植毛され、フィルムのまつ毛植毛部の上方に二重まぶた成形部があり、二重まぶた成形部はまぶたに貼り付けるとまぶたが二重まぶたになる縦幅と横幅であり、フィルム裏面にフィルムをまぶたに付着できる粘着剤が付着されたことを特徴とする付けまつ毛が提案されている（特許文献１）。 In order to improve these problems, for example, a film that can be attached to the eyelid has eyelashes protruding on the surface of the film, and there is a double eyelid molding portion above the eyelash implantation portion of the film. There have been proposed false eyelashes characterized in that when they are attached to the eyelids, the eyelids have a vertical width and a horizontal width that make the eyelids a double eyelid, and an adhesive that can attach the film to the eyelids is attached to the back of the film (Patent Literature) 1).
また、極薄シートからなるベースと該ベースに植え付けられた植毛材と上記ベースの裏面に設けられる粘着層とからなる付けまつ毛であって、上記ベースの厚さはミクロン（μｍ）単位であり、上記粘着層は上記ベースの裏面に突出した植毛材の根部を冠着する凸部と他の部分との間に凹凸が現出される程度の薄さとして上記ベースの裏面全面に均等な厚さで形成され、さらに上瞼に付着したとき上記凸部が上記ベースの表面側に盛り上がり、上記植毛材は上瞼の下縁にそって単数又は複数の列で植え付けられ、該植毛材が植え付けられる基端部を実質上直線状に切り離し可能にするとともに、上記植毛材が植え付けられない先端部が突弧状に切り離し可能にすることを特徴とするつけまつ毛も提案されている（特許文献２）。 Further, false eyelashes consisting of a base made of an ultrathin sheet, a flocking material planted on the base, and an adhesive layer provided on the back surface of the base, and the thickness of the base is in units of microns (μm), The adhesive layer has a uniform thickness over the entire back surface of the base as thin enough that irregularities appear between the convex portion and the other portion that crown the root of the flocking material protruding from the back surface of the base. When the protrusion is further attached to the upper heel, the convex portion rises to the surface side of the base, and the flocking material is planted in one or more rows along the lower edge of the upper heel, and the flocking material is planted. There has also been proposed false eyelashes characterized in that the base end portion can be cut off in a substantially straight line shape and the tip end portion on which the flocking material is not planted can be cut off in a projecting shape (Patent Document 2).
しかしながら、上記の付けまつ毛では、まつ毛が１本ごとに粘着剤に植毛された構成であるため、例えば付けまつ毛にカールをあてるような場合にはまつ毛が個別に離脱しやすくなる。また、上記の付けまつ毛では、汗等の水分を浸透する工夫が十分になされていないため、なお離脱の問題が残っている。 However, in the above false eyelashes, since the eyelashes are each planted in an adhesive, the eyelashes are easily detached individually when curling the false eyelashes, for example. In addition, the above false eyelashes are not sufficiently devised to permeate moisture such as sweat, so that the problem of detachment still remains.
従って、本発明の主な目的は、まつ毛が離脱しにくく、なおかつ、貼着性に優れた付けまつ毛を提供することにある。 Therefore, a main object of the present invention is to provide false eyelashes that are hard to detach the eyelashes and are excellent in sticking property.
本発明者は、従来技術の問題点に鑑みて鋭意研究を重ねた結果、特定の構成を採用することにより上記目的を達成できることを見出し、本発明を完成するに至った。 As a result of intensive studies in view of the problems of the prior art, the present inventor has found that the above object can be achieved by adopting a specific configuration, and has completed the present invention.

The eyelash part 7 has a plurality of eyelashes 6 integrally formed on the support part 5. Next, each component will be described.
貼着部
貼着部は、粘着剤層、透湿性樹脂層及び熱硬化性樹脂層を有し、かつ、前記熱硬化性樹脂層が前記透湿性樹脂層表面上の一部に形成されている。
The sticking part sticking part has an adhesive layer, a moisture permeable resin layer, and a thermosetting resin layer, and the thermosetting resin layer is formed on a part of the surface of the moisture permeable resin layer. .
粘着剤層は、公知又は市販の粘着剤によって形成される層である。粘着剤としては、皮膚に粘着可能なものであれば限定されず、例えばアクリル系粘着剤、シリコン系粘着剤等を用いることができる。特に、本発明では、透湿性等の点からみて、シリコン系粘着剤を好適に用いることができる。また、図１では粘着剤層は透湿性樹脂層の下層に全面に形成されているが、一部に形成されていても良い。例えば、ドット状、ストライプ状、格子状等のいずれの形状も採用することができる。粘着剤層の厚みは限定的ではないが、透湿性等の見地より、通常は２０〜８０μｍ程度とし、特に２５〜６０μｍとすることが好ましい。 The pressure-sensitive adhesive layer is a layer formed of a known or commercially available pressure-sensitive adhesive. The pressure-sensitive adhesive is not limited as long as it can adhere to the skin, and for example, an acrylic pressure-sensitive adhesive or a silicon-based pressure-sensitive adhesive can be used. In particular, in the present invention, a silicon-based pressure-sensitive adhesive can be suitably used from the viewpoint of moisture permeability and the like. In FIG. 1, the pressure-sensitive adhesive layer is formed on the entire lower layer of the moisture-permeable resin layer, but may be formed on a part thereof. For example, any shape such as a dot shape, a stripe shape, and a lattice shape can be employed. The thickness of the pressure-sensitive adhesive layer is not limited, but it is usually about 20 to 80 μm, particularly preferably 25 to 60 μm from the viewpoint of moisture permeability and the like.
透湿性樹脂層は、透湿性を有するものであれば良く、例えばアクリル系樹脂、ポリオレフィン、ポリウレタン等の各種の樹脂を採用することができる。例えば、ポリウレタンをインフレーション成形によって得られた透湿性フィルムを前記透湿性樹脂層として好適に用いることができる。ポリウレタンとしては、ポリエステル系又はポリエーテル系のいずれでも良い。また、ポリウレタンそのものは公知のもの又は市販品を使用することもできる。また、透湿性樹脂層の透湿性（水蒸気透過率）の程度は特に制限されないが、汗等をより効果的に放散できるという点で１０００〜４０００ｇ／ｍ２・２４ｈｒ程度、特に２５００〜４０００ｇ／ｍ２・２４ｈｒとすることが好ましい。透湿性樹脂層の厚みは限定的ではないが、通常は５〜５０μｍ程度とし、特に１０〜３５μｍとすることが好ましい。このようなウレタンシートを用いることによって、ウレタンシートに粘着剤層を形成した後の透湿性も１０００ｇ／ｍ２・２４ｈｒ以上、特に１２００ｇ／ｍ２・２４ｈｒ以上、さらには１４００ｇ／ｍ２・２４ｈｒ以上を維持することができる。 The moisture-permeable resin layer only needs to have moisture permeability, and for example, various resins such as acrylic resin, polyolefin, and polyurethane can be employed. For example, a moisture permeable film obtained by blow molding polyurethane can be suitably used as the moisture permeable resin layer. Polyurethane may be either polyester-based or polyether-based. In addition, the polyurethane itself may be a known one or a commercially available product. Further, the degree of moisture permeability (water vapor permeability) of the moisture-permeable resin layer is not particularly limited, but is about 1000 to 4000 g / m 2 · 24 hr, particularly 2500 to 4000 g / m in that sweat and the like can be more effectively dissipated. 2 · 24 hr is preferable. The thickness of the moisture permeable resin layer is not limited, but is usually about 5 to 50 μm, and preferably 10 to 35 μm. By using such a urethane sheet, the moisture permeability after forming the pressure-sensitive adhesive layer on the urethane sheet is also 1000 g / m 2 · 24 hr or more, particularly 1200 g / m 2 · 24 hr or more, further 1400 g / m 2 · 24 hr or more. Can be maintained.
熱硬化性樹脂層は、まつ毛部と接合するためのものであり、ヒートシール（熱圧着）により硬化し得るものであればいずれのものも採用することができる。例えば、エポキシ樹脂、フェノール樹脂、メラミン樹脂、ポリウレタン、ポリイミド、アクリル系樹脂等の熱硬化性樹脂を適宜選択することができる。熱硬化性樹脂は、透湿性樹脂層の上層の一部に形成すれば良い。すなわち、透湿性樹脂層の上表面の一部を外気に露出するようにすれば良い。これは、例えば図１に示すように、線状の熱硬化性樹脂層を透湿性樹脂層の長手方向に平行になるように透湿性樹脂層上に形成することができる。この場合の線幅は限定的ではないが、一般的には０．５〜２ｍｍ程度とすれば良い。このように、熱硬化性樹脂を透湿性樹脂層の上層の一部に形成することによって、汗等を効果的に外気中に放出することができる。熱硬化性樹脂層の厚みは限定的ではないが、通常は５０〜７０μｍ程度とし、特に５５〜６５μｍとすることが好ましい。また、熱硬化性樹脂層を線状に形成する場合の線幅は、用いるまつ毛部の支持部の幅に合わせるようにすれば良く、通常は０．５〜１．５ｍｍの範囲内で適宜調整することができる。 The thermosetting resin layer is for bonding to the eyelash part, and any one can be adopted as long as it can be cured by heat sealing (thermocompression bonding). For example, a thermosetting resin such as an epoxy resin, a phenol resin, a melamine resin, polyurethane, polyimide, or an acrylic resin can be appropriately selected. What is necessary is just to form a thermosetting resin in a part of upper layer of a moisture-permeable resin layer. That is, a part of the upper surface of the moisture-permeable resin layer may be exposed to the outside air. For example, as shown in FIG. 1, a linear thermosetting resin layer can be formed on the moisture-permeable resin layer so as to be parallel to the longitudinal direction of the moisture-permeable resin layer. The line width in this case is not limited, but generally it may be about 0.5 to 2 mm. Thus, by forming the thermosetting resin in a part of the upper layer of the moisture-permeable resin layer, sweat or the like can be effectively released into the outside air. Although the thickness of a thermosetting resin layer is not limited, Usually, it is about 50-70 micrometers, and it is preferable to set it as 55-65 micrometers especially. In addition, the line width when the thermosetting resin layer is formed in a linear shape may be adjusted to the width of the support portion of the eyelash portion to be used, and is usually adjusted appropriately within a range of 0.5 to 1.5 mm. can do.
また、本発明では、粘着剤層の下層として離型紙を積層しても良い。例えば、合成樹脂（ポリエチレンテレフタレート等）製シート又はフィルム、紙等の公知の離型紙を採用することができる。これによって、粘着剤層を使用時まで保護し、使用時に離型紙を剥がして皮膚に貼着することができる。 In the present invention, a release paper may be laminated as a lower layer of the pressure-sensitive adhesive layer. For example, a known release paper such as a synthetic resin (polyethylene terephthalate or the like) sheet or film or paper can be employed. Thus, the pressure-sensitive adhesive layer can be protected until use, and the release paper can be peeled off at the time of use and adhered to the skin.
まつ毛部
まつ毛部は、線状の支持部に複数のまつ毛が一体的に固定されたものであって、かつ、前記支持部が前記熱硬化性樹脂層を介して前記貼着部に接合されている。
The eyelash part is an eyelash part in which a plurality of eyelashes are integrally fixed to a linear support part, and the support part is joined to the sticking part via the thermosetting resin layer. Yes.
支持部の材質は限定されないが、通常は合成樹脂、合成ゴム、金属（合金）等を単独又は２つ以上組合せて用いることができる。支持部は貼着部とともに瞼に追従するように湾曲されていることが好ましい。支持部が湾曲することにより貼着部も湾曲するため、本発明の付けまつ毛の装着時において付けまつ毛が瞼により追従しやすくなる。湾曲させる方法は公知の加工方法に従えば良い。また、その加工手順は、１）支持部を貼着部に接合する前において予め支持部を湾曲させる方法、２）支持部と貼着部を接合しながら湾曲させる方法、３）支持部と貼着部を接合した後、支持部と貼着部をともに湾曲させる方法等のいずれであっても良い。加工手段としては、公知の方法に従えば良く、例えば湾曲した熱版又は型を加熱した後、支持部（又は支持部と貼着部）を湾曲状に成形することができる。また、支持部として形状記憶合金を用いることができる。この場合、例えば所望の湾曲状に形状を予め記憶させておいた上で、製造工程では支持部を直線状で取扱い、製造仕上げ段階又は付けまつ毛使用時において湾曲状に戻るように設計することもできる。 The material of the support portion is not limited, but usually, synthetic resin, synthetic rubber, metal (alloy), or the like can be used alone or in combination of two or more. It is preferable that the support part is curved so as to follow the heel together with the sticking part. Since the support portion is curved, the sticking portion is also curved, so that the false eyelashes can easily follow the eyelashes when the false eyelashes of the present invention are attached. The method of bending may follow a known processing method. The processing procedure is as follows: 1) a method of bending the support portion in advance before joining the support portion to the sticking portion, 2) a method of bending the support portion and the sticking portion while joining, and 3) a support portion and sticking. Any method such as a method of bending the support part and the sticking part together after joining the attaching part may be used. As a processing means, a known method may be followed. For example, after heating a curved hot plate or mold, the support part (or the support part and the sticking part) can be formed into a curved shape. Moreover, a shape memory alloy can be used as a support part. In this case, for example, the shape may be stored in advance in a desired curved shape, and the support portion may be handled in a straight line in the manufacturing process, and may be designed to return to the curved shape in the manufacturing finishing stage or when using false eyelashes. it can.

In joining the eyelash part, it can be obtained by a method for producing false eyelashes, which includes a step of joining the support part and the thermosetting resin layer by thermocompression bonding.
貼着部は、各層を積層することによって製造することができる。例えば、透湿性樹脂シートの裏面に粘着剤層を形成するとともに、透湿性樹脂シートのおもて面に熱硬化性樹脂層を形成すれば良い。粘着剤層の形成は、例えば液状粘着剤を透湿性樹脂シートの裏面に塗布することによって実施することができる。また、粘着シート（例えば両面テープ）の片面を透湿性樹脂シートの裏面に貼着することにより粘着剤層を形成することもできる。熱硬化性樹脂層の形成は、例えば熱硬化性樹脂を含む粘着シートを透湿性樹脂のおもて面に貼着する方法のほか、熱硬化性樹脂を含む溶液又は分散液を透湿性樹脂シートのおもて面に塗布する方法等によって実施することができる。 A sticking part can be manufactured by laminating | stacking each layer. For example, the pressure-sensitive adhesive layer may be formed on the back surface of the moisture-permeable resin sheet and the thermosetting resin layer may be formed on the front surface of the moisture-permeable resin sheet. Formation of an adhesive layer can be implemented by apply | coating a liquid adhesive to the back surface of a moisture-permeable resin sheet, for example. Moreover, an adhesive layer can also be formed by sticking the single side | surface of an adhesive sheet (for example, double-sided tape) to the back surface of a moisture-permeable resin sheet. The thermosetting resin layer is formed by, for example, a method of sticking a pressure-sensitive adhesive sheet containing a thermosetting resin to the front surface of the moisture-permeable resin, and a solution or dispersion containing the thermosetting resin as a moisture-permeable resin sheet. It can be carried out by a method of applying to the front surface.
貼着部の熱硬化性樹脂層とまつ毛部の支持部とを熱圧着（ヒートシール）によって接合する。熱圧着時の温度条件は、熱硬化性樹脂の種類等によって異なるが、一般的には１００〜１５０℃とし、特に１１０〜１３０℃とすることが好ましい。また、圧力は、０．０３〜０．３ＭＰａ程度の範囲内で適宜設定することができる。熱圧着の時間は通常１〜２０秒程度とすれば良い。熱圧着によって、貼着部とまつ毛部とが短時間で強固に接合することが可能となる。本発明では、熱圧着（ヒートシール）は、公知又は市販のヒートシール装置を使用すれば良い。 The thermosetting resin layer of the sticking part and the support part of the eyelash part are joined by thermocompression bonding (heat sealing). Although the temperature conditions at the time of thermocompression bonding differ depending on the type of the thermosetting resin, etc., it is generally 100 to 150 ° C., particularly preferably 110 to 130 ° C. Moreover, a pressure can be suitably set within the range of about 0.03-0.3 MPa. The time for thermocompression bonding is usually about 1 to 20 seconds. By the thermocompression bonding, it is possible to firmly bond the sticking part and the eyelash part in a short time. In the present invention, a known or commercially available heat sealing device may be used for thermocompression bonding (heat sealing).
この場合、図３（ａ）に示すように、互いに噛み合う２枚の湾曲状熱版３１を備えたヒートシール装置を用い、２つの熱版３１の間で貼着部の熱硬化性樹脂層とまつ毛部の支持部との熱圧着（ヒートシール）を行うことによって湾曲状の製品３２を得ることができる。この製品３２は、予め湾曲状に形成された複数の付けまつ毛が繋がった状態であるが、これを図３（ｂ）のように１つずつ切り離せば、湾曲状に形成された複数の付けまつ毛３３を同時に得ることができる。これにより、まぶたにフィットできる付けまつ毛をより効率的に製造することができる。なお、本発明では、付けまつ毛１つずつを前記のようなヒートシール装置でヒートシールして湾曲状の付けまつ毛３２を１つずつ製造しても良い。 In this case, as shown in FIG. 3 (a), using a heat seal device provided with two curved hot plates 31 meshing with each other, the thermosetting resin layer of the sticking portion between the two hot plates 31 and The curved product 32 can be obtained by performing thermocompression bonding (heat sealing) with the support part of the eyelash part.
