　(第１実施形態)
　図１に示される美容シート１は保持層３１(図２参照)に含浸される美容成分を含む化粧料によってユーザの肌の手入れを行なうためのシートである。化粧料の一例は透明ローション、白濁ローション、乳液、および、クリームである。化粧料の状態は任意に選択できる。好ましい例では、化粧料の状態は液体またはペーストである。美容シート１の形態は任意に選択できる。図１に示される第１例では、美容シート１の形態はユーザの顔に貼り付けられるフェイスマスクである。第２例では、美容シート１の形態はユーザの身体のうちの顔以外の任意の箇所に貼り付けられるシートである。美容シート１の形状は任意に選択できる。図１に示される第１例では、美容シート１は上部１０と下部２０とに分かれた形状である。第２例では、美容シート１は上部１０と下部２０とが繋がった形状、または、３つ以上に分かれた形状である。 (First embodiment)
The beauty sheet 1 shown in FIG. 1 is a sheet for caring for a user's skin with a cosmetic containing a beauty component impregnated in the holding layer 31 (see FIG. 2). Examples of cosmetics are clear lotions, cloudy lotions, emulsions and creams. The state of the cosmetic can be arbitrarily selected. In a preferred example, the cosmetic state is a liquid or a paste. The form of the beauty sheet 1 can be arbitrarily selected. In the first example shown in FIG. 1, the form of the beauty sheet 1 is a face mask that is attached to the user's face. In the second example, the form of the beauty sheet 1 is a sheet that can be attached to any part of the user's body other than the face. The shape of the beauty sheet 1 can be arbitrarily selected. In the first example shown in FIG. 1, the beauty sheet 1 has a shape divided into an upper part 10 and a lower part 20. In the second example, the beauty sheet 1 has a shape in which the upper part 10 and the lower part 20 are connected, or a shape divided into three or more.
　上部１０はユーザの顔のうちの鼻から額を覆う。上部１０は孔１１、および、複数のスリット１２を備える。孔１１はユーザの目に対応する形状である。スリット１２はユーザの鼻翼に対応する形状である。下部２０はユーザの顔のうちの人中および頬から顎を覆う。下部２０は孔２１、および、複数のスリット２２を備える。孔２１はユーザの口に対応する形状である。複数のスリット２２は美容シート１をユーザの顔に貼り付けたときに美容シート１のうちのフェイスラインに対応する部分にしわが形成されにくくするために設けられる。 The upper part 10 covers the forehead from the nose of the user's face. The upper part 10 has a hole 11 and a plurality of slits 12. The hole 11 has a shape corresponding to the eyes of the user. The slit 12 has a shape corresponding to the nose wing of the user. The lower part 20 covers the chin from all over the user's face and from the cheeks. The lower part 20 includes a hole 21 and a plurality of slits 22. The hole 21 has a shape corresponding to the mouth of the user. The plurality of slits 22 are provided to make it difficult for wrinkles to be formed in a portion of the beauty sheet 1 corresponding to the face line when the beauty sheet 1 is attached to the face of the user.
　従来の美容シートでは美観について特に考慮されていない。その理由の１つは美容シートの典型的な使用例であると考えられる。美容シートの典型的な使用例では、ユーザは室内等のプライベート空間で美容シートを肌に貼り付け、所定時間の経過後に美容シートを肌から剥がして捨てる。このように、美容シートはユーザのプライベート空間で一時的に使用されるものであるため、美観については特に考慮されていなかったと考えられる。美容シートがユーザのプライベート空間で一時的に使用されるものであっても美観が高められることにより、美容シートの付加価値が一層高くなると考えられる。美容シート１は美観が高められるように構成された美容シートの一例である。 美 Aesthetics are not specifically considered in conventional beauty sheets. One of the reasons is considered to be a typical use example of the beauty sheet. In a typical usage example of a beauty sheet, a user attaches the beauty sheet to the skin in a private space such as a room, and after a predetermined time elapses, peels off the beauty sheet from the skin and discards it. As described above, since the beauty sheet is used temporarily in the private space of the user, it is considered that the beauty is not particularly considered. Even if the beauty sheet is used temporarily in the user's private space, it is considered that the added value of the beauty sheet is further increased by enhancing the beauty. The beauty sheet 1 is an example of a beauty sheet configured to enhance beauty.
　図２に示されるように、美容シート１は保持層３１、中間層３２、光沢層３３、および、保護層３４が積層された４層構造を備える。保持層３１は化粧料を保持する。保持層３１を構成する材料は任意に選択できる。保持層３１を構成する材料は例えば、天然繊維、合成繊維、水溶性合成樹脂、および、含水性ゲルシートである。保持層３１の一方の面３１Ａはユーザの肌と接触する面である。なお、上部１０および下部２０の層構成は同一である。 美容 As shown in FIG. 2, the beauty sheet 1 has a four-layer structure in which a holding layer 31, an intermediate layer 32, a gloss layer 33, and a protective layer 34 are laminated. The holding layer 31 holds the cosmetic. The material forming the holding layer 31 can be arbitrarily selected. The material forming the holding layer 31 is, for example, a natural fiber, a synthetic fiber, a water-soluble synthetic resin, and a hydrogel sheet. One surface 31A of the holding layer 31 is a surface that comes into contact with the skin of the user. The upper 10 and the lower 20 have the same layer configuration.
　中間層３２は保持層３１と光沢層３３とを接合する。中間層３２を構成する材料は任意に選択できる。中間層３２を構成する材料は例えば、押出ポリエチレンおよび接着材である。中間層３２は保持層３１の他方の面３１Ｂに積層される。中間層３２の厚さは任意に選択できる。中間層３２の厚さは例えば、５μｍ～５０μｍの範囲に含まれる。一例では、中間層３２の厚さは１５μｍである。 The intermediate layer 32 joins the holding layer 31 and the gloss layer 33. The material constituting the intermediate layer 32 can be arbitrarily selected. The material forming the intermediate layer 32 is, for example, extruded polyethylene and an adhesive. The intermediate layer 32 is laminated on the other surface 31B of the holding layer 31. The thickness of the intermediate layer 32 can be arbitrarily selected. The thickness of the intermediate layer 32 is, for example, in the range of 5 μm to 50 μm. In one example, the thickness of the intermediate layer 32 is 15 μm.
　光沢層３３は美観を高めることに寄与する。光沢層３３は中間層３２を介して保持層３１に積層される。光沢層３３を構成する材料は光沢を有する材料から任意に選択できる。光沢層３３を構成する材料は例えば、アルミニウム箔、アルミニウムペーストを含むインキ(銀インキ)、パール顔料を含むインキ、アルミニウム箔が蒸着された合成樹脂、および、スズが蒸着された合成樹脂である。アルミニウム箔が蒸着された合成樹脂、および、スズが蒸着された合成樹脂の一例はポリエチレンおよびポリエチレンテレフタレートである。光沢層３３の厚さは例えば、０．５μｍ～３０μｍの範囲に含まれる。一例では、光沢層３３の厚さは７μｍである。 The gloss layer 33 contributes to enhancing the appearance. The gloss layer 33 is laminated on the holding layer 31 via the intermediate layer 32. The material constituting the gloss layer 33 can be arbitrarily selected from glossy materials. The material constituting the gloss layer 33 is, for example, aluminum foil, ink containing silver paste (silver ink), ink containing pearl pigment, synthetic resin on which aluminum foil is deposited, and synthetic resin on which tin is deposited. Examples of the synthetic resin on which aluminum foil is deposited and the synthetic resin on which tin is deposited are polyethylene and polyethylene terephthalate. The thickness of the gloss layer 33 is, for example, in the range of 0.5 μm to 30 μm. In one example, the thickness of the gloss layer 33 is 7 μm.
　保護層３４は光沢層３３を保護する。このため、光沢層３３が劣化しにくい。保護層３４は光沢層３３のうちの保持層３１と反対側に積層される。すなわち、光沢層３３は、保持層３１に対向する第１の面（図２における下側の面）と、第１の面と反対側の第２の面（図２における上側の面）と、を有している。保護層３４は、光沢層３３の第２の面に設けられる。保護層３４を構成する材料は任意に選択できる。保護層３４を構成する材料は例えば、エポキシ樹脂およびアクリル樹脂である。エポキシ樹脂の一例は、ビスフェノールＡ型エポキシ樹脂である。アクリル樹脂の一例は、ポリメタクリル酸メチル樹脂(ＰＭＭＡ)である。保護層３４がエポキシ樹脂を含む場合、美容シート１がユーザの肌に貼り付けられたときに、ごわつきにくい。好ましい例では、保護層３４を構成する材料は着色剤を含む。このため、美観が一層高められる。着色剤は例えば、顔料または染料である。顔料および染料の色の一例はピンクである。保護層３４の厚さは例えば、０．５μｍ～７μｍの範囲に含まれる。保護層３４の厚さがこの範囲に含まれる場合、美容シート１がユーザの肌に貼り付けられたときに、ごわつきにくい。一例では、保護層３４の厚さは３μｍである。 (4) The protective layer 34 protects the gloss layer 33. For this reason, the gloss layer 33 does not easily deteriorate. The protective layer 34 is laminated on the gloss layer 33 on the side opposite to the holding layer 31. That is, the glossy layer 33 includes a first surface (a lower surface in FIG. 2) facing the holding layer 31, a second surface opposite to the first surface (an upper surface in FIG. 2), have. The protection layer 34 is provided on the second surface of the gloss layer 33. The material forming the protective layer 34 can be arbitrarily selected. The material forming the protective layer 34 is, for example, an epoxy resin and an acrylic resin. One example of the epoxy resin is a bisphenol A type epoxy resin. One example of an acrylic resin is polymethyl methacrylate resin (PMMA). When the protective layer 34 contains an epoxy resin, when the beauty sheet 1 is stuck on a user's skin, it is hard to be stiff. In a preferred example, the material forming the protective layer 34 includes a coloring agent. For this reason, the appearance is further enhanced. The colorant is, for example, a pigment or a dye. An example of a pigment and dye color is pink. The thickness of the protective layer 34 is, for example, in the range of 0.5 μm to 7 μm. When the thickness of the protective layer 34 is included in this range, when the beauty sheet 1 is stuck on the skin of the user, it is hard to be stiff. In one example, the thickness of the protective layer 34 is 3 μm.
　美容シート１の製造方法の一例について説明する。美容シート１の製造方法は第１工程および第２工程を含む。第１工程では、光沢層３３に保護層３４が焼き付けコートされる。第２工程では、保護層３４が焼き付けコートされた光沢層３３と保持層３１とが中間層３２を介在させた状態でラミネート加工される。中間層３２を構成する材料が押出ポリエチレンである場合、保護層３４が焼き付けコートされた光沢層３３と保持層３１とのラミネート法は押出しコートラミネート法である。中間層３２を構成する材料が接着剤である場合、保護層３４が焼き付けコートされた光沢層３３と保持層３１とのラミネート法はドライラミネート法である。 An example of a method for manufacturing the beauty sheet 1 will be described. The method for manufacturing the beauty sheet 1 includes a first step and a second step. In the first step, the glossy layer 33 is coated with the protective layer 34 by baking. In the second step, the glossy layer 33 on which the protective layer 34 is baked and coated and the holding layer 31 are laminated with the intermediate layer 32 interposed therebetween. When the material constituting the intermediate layer 32 is extruded polyethylene, the lamination method of the glossy layer 33 on which the protective layer 34 is baked and coated and the holding layer 31 is an extrusion coat lamination method. When the material forming the intermediate layer 32 is an adhesive, the laminating method of the glossy layer 33 on which the protective layer 34 is baked and coated and the holding layer 31 is a dry laminating method.

　試験では、実施例１～５、および、比較例１の試料のＭＤ(Machine Direction)方向およびＴＤ(Transverse Direction)方向のループステフネスを株式会社東洋精機製作所製のループステフネステスタ(登録商標)を用いて測定した。ループステフネステスタは、マグネットテープやフィルムなど極薄材料のステフネスを評価するもので、ループ状の極薄材料のつぶれ抵抗を測定する。図７に示されるように、実施例１～４の試料はループステフネスが比較的低いことが確認された。このため、実施例１～４の試料に関する美容シート１がユーザの肌に貼り付けられたときに、ごわつきにくい。また、実施例１～４の試料は光沢層、および、着色剤を含む保護層を備えるため、美観が非常に高いことが確認された。実施例５の試料はループステフネスが若干高い。このため、実施例５に関する美容シート１がユーザの肌に貼り付けられたときに、若干ごわつく。また、実施例５の試料は光沢層を備えるため、美観が高いことが確認された。比較例１の試料は保持層のみを備えるため、ループステフネスが極めて低いことが確認された。また、比較例１の試料は光沢層、および、着色剤を含む保護層のいずれの層も有さないため、美観が極めて低いことが確認された。 In the test, the loop stiffness in the MD (Machine Direction) direction and the TD (Transverse Direction) direction of the samples of Examples 1 to 5 and Comparative Example 1 were measured using Loop Stiffness Tester (registered trademark) manufactured by Toyo Seiki Seisakusho Co., Ltd. It measured using. The loop stiffness tester evaluates the stiffness of an ultra-thin material such as a magnetic tape or a film, and measures the crush resistance of a loop-shaped ultra-thin material. As shown in FIG. 7, it was confirmed that the samples of Examples 1 to 4 had relatively low loop stiffness. For this reason, when the beauty sheet 1 relating to the samples of Examples 1 to 4 is stuck on the skin of the user, it is hard to be stiff. In addition, since the samples of Examples 1 to 4 were provided with the glossy layer and the protective layer containing the coloring agent, it was confirmed that the appearance was very high. The sample of Example 5 has a slightly higher loop stiffness. Therefore, when the beauty sheet 1 according to the fifth embodiment is stuck on the skin of the user, it is slightly stiff. Moreover, since the sample of Example 5 was provided with the glossy layer, it was confirmed that the appearance was high. Since the sample of Comparative Example 1 was provided with only the holding layer, it was confirmed that the loop stiffness was extremely low. Further, since the sample of Comparative Example 1 did not have any of the glossy layer and the protective layer containing the colorant, it was confirmed that the appearance was extremely low.
　(変形例)
　なお、上記第１実施形態は本発明に関する美容シートが取り得る形態の例示であり、その形態を制限することを意図していない。本発明に関する美容シートは第１実施形態に例示された形態とは異なる形態を取り得る。その一例は、第１実施形態の構成の一部を置換、変更、もしくは、省略した形態、または、第１実施形態に新たな構成を付加した形態である。以下に第１実施形態の変形例の一例を示す。 (Modification)

　（第２実施形態）
　以下、本発明の第２実施形態を図８～図１３を参照しながら、更に詳しい説明を加える。ただし本発明は、ここに示す例にのみ限定されるものではない。本発明は、請求項によって限定されるものである。 (2nd Embodiment)
Hereinafter, the second embodiment of the present invention will be described in more detail with reference to FIGS. However, the present invention is not limited only to the examples shown here. The invention is limited by the claims.
　図８は、本発明に係る美容シートの一例であるフェイスマスクの基本構成を説明するための、部分断面模式図である。
　本発明は、美容や肌の手入れに用いる美容シートとしてのフェイスマスク（６０４）に関するものである。このフェイスマスク（６０４）は、肌に接する側から順に積層された保水層（６０１）、光沢層（６０２）、保護層（６０３）を含む。 FIG. 8 is a schematic partial cross-sectional view for explaining a basic configuration of a face mask which is an example of a beauty sheet according to the present invention.
The present invention relates to a face mask (604) as a beauty sheet used for beauty and skin care. The face mask (604) includes a water retention layer (601), a gloss layer (602), and a protection layer (603) which are sequentially stacked from the side in contact with the skin.
　このうち、保水層（６０１）は不織布を含む。保水層（６０１）が不織布であることによって、美容や肌の手入れのための成分を含む化粧水などの液体をフェイスマスク中に保持しておくことができ、フェイスマスクとしての使用時には、美容や肌の手入れのための成分を、肌の表面に満遍なくいきわたらせることができる。 う ち Among these, the water retention layer (601) includes a nonwoven fabric. Since the water retaining layer (601) is a nonwoven fabric, a liquid such as a lotion containing components for beauty and skin care can be retained in the face mask. Ingredients for skin care can be spread evenly on the surface of the skin.
　また、光沢層（６０２）は、金属光沢の意匠性を表現するために、金属箔、または金属蒸着フィルム、または金属を含むコーティング層を表面に有するフィルム、を含む。この金属には、たとえばアルミニウム、スズ、などの金属を用いることができる。 光 沢 The gloss layer (602) includes a metal foil, a metal vapor-deposited film, or a film having a metal-containing coating layer on the surface in order to express the design of metallic luster. As the metal, for example, a metal such as aluminum or tin can be used.
　金属箔であれば、たとえばアルミニウム、スズなどの金属箔を層として積層して用いることができる。
　また、金属蒸着フィルムであれば、たとえばアルミニウム、スズなどの金属を、プラスチックフィルムの表面に真空蒸着をして被膜形成したものを用いることができる。 If it is a metal foil, for example, a metal foil of aluminum, tin, or the like can be used as a layer.
Further, in the case of a metal vapor-deposited film, for example, a film obtained by vacuum-depositing a metal such as aluminum or tin on the surface of a plastic film to form a film can be used.
　また金属を含むコーティング層を表面に有するフィルムは、たとえばアルミニウムやスズなどの金属の微粒子を、インキ化あるいは塗料化して、印刷手法やコーティング手法を用いてプラスチックフィルムの表面に塗膜形成して用いることができる。 In addition, a film having a coating layer containing a metal on the surface is used, for example, by forming fine particles of a metal such as aluminum or tin into an ink or a paint, and forming a coating film on the surface of the plastic film using a printing technique or a coating technique. be able to.
　また、保護層（６０３）は樹脂層を含む。本発明は、この樹脂層の曲げ剛性率が、１０～１５０ＭＰａの範囲であることを特徴とする、フェイスマスク（６０４）である。我々は、本発明を鋭意検討した結果、曲げ剛性率が、１０～１５０ＭＰａの範囲であることによって、フェイスマスク（６０４）として光沢層を有して美観に優れ、かつ適度な柔軟性を有して装着時のフィット感に優れるフェイスマスク（６０４）を実現することが可能であることを見出した。 (4) The protective layer (603) includes a resin layer. The present invention provides the face mask (604), wherein the resin layer has a flexural rigidity in a range of 10 to 150 MPa. As a result of intensive studies of the present invention, we found that the flexural modulus in the range of 10 to 150 MPa provided the face mask (604) with a glossy layer, excellent aesthetics, and appropriate flexibility. It has been found that it is possible to realize a face mask (604) which is excellent in fit when worn.
　本発明においては、樹脂層の曲げ剛性率が、１０～１５０ＭＰａの範囲であるが、この範囲を超える場合には、フェイスマスクは硬い感じであって、装着時にごわつく結果となる。また反対に曲げ剛性率が１０ＭＰａに満たない場合には、安定したラミネート加工ができなくなり実用は困難である。 に お い て In the present invention, the flexural rigidity of the resin layer is in the range of 10 to 150 MPa. If the flexural modulus exceeds this range, the face mask will be hard and will be hard when worn. Conversely, if the flexural rigidity is less than 10 MPa, stable lamination cannot be performed, and practical use is difficult.
　この樹脂層に用いる樹脂には特段の制限を設けるものでは無いが、たとえばエチレン・メチルメタクリレート共重合体（ＥＭＭＡ）、エチレン・酢酸ビニル共重合体（ＥＶＡ）、エチレン・メタクリル酸共重合体（ＥＭＭＡ）、アイオノマーなどを用いることができる。 Although there is no particular limitation on the resin used for this resin layer, for example, ethylene / methyl methacrylate copolymer (EMMA), ethylene / vinyl acetate copolymer (EVA), ethylene / methacrylic acid copolymer (EMMA) ), Ionomers and the like can be used.
