Description

本発明は、口及び鼻先を含む顔面の対象部位を覆うマスクに関するものである。   The present invention relates to a mask that covers a target portion of a face including a mouth and a nose tip.

従来、マスクとしては、ガーゼを複数枚重ねて矩形状となし、その左右両側に耳掛け用のゴム紐を環状に取り付けたものが汎用されてきた。これらは形状的には平板マスクということができるタイプである。   Conventionally, a mask in which a plurality of gauze is formed into a rectangular shape and rubber bands for ear hooks are attached in an annular shape on both right and left sides has been widely used. These are types that can be called flat plate masks in terms of shape.

近年では、使い捨てを目的として、不織布を使用したマスクが開発されており、使用時において、口許、鼻の膨らみに追従して形状変形するもの（例えば特許文献１及び特許文献２参照）が提案され、商品化させているものもある。これらは形状的には立体マスクということができるタイプである。   In recent years, masks using non-woven fabrics have been developed for the purpose of disposable use, and in use, masks that deform in shape following the lip of the mouth and nose have been proposed (for example, see Patent Document 1 and Patent Document 2). Some are commercialized. These are types that can be called three-dimensional masks in terms of shape.

特許文献１のものは、耳掛け部が横方向に伸長するように形成され、覆い部（本発明の本体部に実質的に該当する）は、剛性を高くし、ほとんど伸長することがないようにすることで、覆い部の膨らみを維持し、マスクを着用する際に、口許や鼻孔の周辺に比較的広い空間を確保することができて、楽に呼吸をすることができるようにしたものである。   The thing of patent document 1 is formed so that an ear hooking part may be extended in a horizontal direction, and a cover part (substantially corresponds to the main-body part of this invention) makes rigidity high, and it is hardly extended. By keeping the bulge of the cover part, when wearing a mask, a relatively wide space can be secured around the mouthpiece and nostril so that you can breathe easily. is there.

この発明の利点は大きいものの、人には各様の顔面骨格（プロフィール及び大小）を有しており、単に横方向（口及び鼻から耳にかけての方向を言う。これに対し、縦方向は横方向に直交する方向を言う。）の伸縮性をもたせるだけで、マスクとしての汎用性を確保することは困難である。   Although the advantages of the present invention are great, a person has various facial skeletons (profile and size) and simply refers to the lateral direction (the direction from the mouth and nose to the ear. It is difficult to ensure general versatility as a mask only by having a stretchability of the direction perpendicular to the direction.

特に、鼻の両脇と対向する部分は、鼻梁及び鼻翼の突出によって隙間を生じやすく、花粉やウイルスの侵入を防止し難いという問題点がある。また、このような隙間があると、呼吸に伴って口や鼻から排出された湿気が、上端部から外部に排出されるようになるため、眼鏡着用者においては眼鏡が曇るという問題点もある。
特許３６６００３６号公報 特開２００４‐４９３５６号公報 In particular, there is a problem that the portions facing both sides of the nose are liable to cause a gap due to the projection of the nose bridge and the nose wings, and it is difficult to prevent the entry of pollen and viruses. In addition, if there is such a gap, the moisture discharged from the mouth and nose with breathing will be discharged to the outside from the upper end portion, so there is also a problem that the spectacles become cloudy in the spectacle wearer .
Japanese Patent No. 3660036 JP 2004-49356 A

そこで、本発明の主たる課題は、顔面に対するフィット性に優れたマスクを提供することにある。   Then, the main subject of this invention is providing the mask excellent in the fitting property with respect to a face.

上記課題を解決した本発明は次記のとおりである。
＜請求項１記載の発明＞
口及び鼻先を含む顔面の対象部位を覆う本体部と、この本体部を身体に係止するための係止部とを有し、
口及び鼻先と対向する部分が、その周囲部分よりも外側に膨出する立体形状を有する立体マスクにおいて、
本体部の鼻の両脇と対向する部分が、外側層、内側層およびこれらの間に配置された圧縮復元層からなる三層構造を有し、
前記圧縮復元層は、厚さが１〜１０ｍｍであり、ＪＩＳ Ｌ １０９６ ８．２７．１ Ａ法により測定される、前記圧縮復元層の通気度が５０〜４００ｃｃ／ｃｍ 2 ・ｓｅｃであり、ＪＩＳ−Ｚ−０２０８による透湿度が５０〜３００ｇ／ｍ 2 ｈｒである、
ことを特徴とするマスク。 The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
A main body covering the target portion of the face including the mouth and nose tip, and a locking portion for locking the main body to the body ,
In the three-dimensional mask having a three-dimensional shape in which the part facing the mouth and nose tip bulges outward from the surrounding part,
The part of the main body that faces both sides of the nose has a three-layer structure consisting of an outer layer, an inner layer, and a compression decompression layer disposed therebetween,
The compression restoration layer has a thickness of 1 to 10 mm, and has an air permeability of 50 to 400 cc / cm 2 · sec as measured according to JIS L 1096 8.27.1 A method. The water vapor transmission rate by -Z-0208 is 50-300 g / m < 2 > hr,
A mask characterized by that.

（作用効果）
本発明では、圧縮復元層を有することにより、顔面形状に追従して厚さが変化するため、顔面に対するフィット性に優れたものとなる。また、圧縮復元層は外側層と内側層との間に配置されるため、圧縮復元層が外面や内面に露出する場合と異なり、外観や肌触りの悪化を防止しつつフィット性を向上できる。特に、圧縮復元層を不織布等の繊維集合体により形成する場合には嵩高な素材を使用することになるが、このような素材は肌触りが悪くなりやすいため、本発明の三層構造を採用することによる利益が大きい。なお、本明細書で使用する「フィット性」は肌全体に密着することを意味するのではなく、マスクとして密着が必要な部位においては密着し、内部に呼吸に必要な空間を確保しながら、顔面に対して良好に追従することを意味するのである。
特に立体マスクは、特に鼻周りにおけるフィット性に乏しいため、本発明を適用するのに向いているものである。 (Function and effect)
In the present invention, since the thickness changes following the face shape by having the compression restoration layer, the fit to the face is excellent. In addition, since the compression restoration layer is disposed between the outer layer and the inner layer, unlike the case where the compression restoration layer is exposed on the outer surface or the inner surface, the fit can be improved while preventing the appearance and the touch from being deteriorated. In particular, when the compression restoration layer is formed of a fiber assembly such as a nonwoven fabric, a bulky material is used. However, since such a material is likely to be unpleasant to the touch, the three-layer structure of the present invention is adopted. Profits are great. In addition, "fitness" used in this specification does not mean that it adheres to the entire skin, but in close contact with a part that requires close contact as a mask, while ensuring a space necessary for breathing inside, It means to follow the face well.
In particular, the three-dimensional mask is particularly suitable for applying the present invention because it has poor fit around the nose.

また、鼻の両脇と対向する部分は、鼻梁及び鼻翼の突出によって隙間を生じやすいため、この部分に本発明の三層構造を設けるのは好ましい。フィット性の向上により、隙間が発生し難くなり、花粉やウイルス等の異物侵入を効果的に防止できるだけでなく、眼鏡着用者にあっては眼鏡の曇りも抑制できるようになる。   Moreover, since the part which opposes both sides of a nose is easy to produce a clearance gap by the protrusion of a nose bridge and a nose wing, it is preferable to provide the three-layer structure of this invention in this part. The improved fit makes it difficult for gaps to occur, and can effectively prevent foreign substances such as pollen and viruses from entering, and can also suppress fogging of spectacles for spectacle wearers.

＜請求項２記載の発明＞
前記圧縮復元層の圧縮レジリエンスＲＣが５０％以上である請求項１記載のマスク。 <Invention of Claim 2>
The mask according to claim 1, wherein the compression resilience RC of the compression restoration layer is 50% or more.

（作用効果）
圧縮レジリエンスＲＣがこの範囲内にあると、顔面凹凸に対する形状追従性が十分に発揮され、特にフィット性に優れたものとなる。なお、圧縮レジリエンス（ＲＣ）とは、素材が圧縮されたときの回復性を表すパラメータであり、回復性がよければ、圧縮レジリエンスが大きくなる。この圧縮レジリエンスは、ハンディー圧縮試験機（ＫＥＳ−Ｇ５、カトーテック社製）によって測定することができる。この試験機による場合の測定条件は、ＳＥＮＳ：２、力計の種類：１ｋｇ、ＳＰＥＥＤ ＲＡＮＧＥ：ＳＴＤ、ＤＥＦ感度：２０、加圧面積：２ｃｍ2、取り込間隔：０．１（標準）、ＳＴＲＯＫＥ ＳＥＴ：５．０、上限荷重：５０ｇｆ／ｃｍ2である。 (Function and effect)
When the compression resilience RC is within this range, the shape followability with respect to the facial irregularities is sufficiently exhibited, and the fit is particularly excellent. Note that the compression resilience (RC) is a parameter representing the recoverability when the material is compressed. If the recoverability is good, the compression resilience increases. This compression resilience can be measured with a handy compression tester (KES-G5, manufactured by Kato Tech). The measurement conditions for this tester are: SENS: 2, force meter type: 1 kg, SPEED RANGE: STD, DEF sensitivity: 20, pressurization area: 2 cm 2 , capture interval: 0.1 (standard), STROKE SET: 5.0, upper limit load: 50 gf / cm 2 .

＜請求項３記載の発明＞<Invention of Claim 3>
前記圧縮復元層が折り畳まれた圧縮復元性素材からなる請求項１又は２記載のマスク。The mask according to claim 1, wherein the compression restoration layer is made of a compression restoration material.
＜請求項４記載の発明＞<Invention of Claim 4>
前記圧縮復元層が複数層積み重ねられた圧縮復元性素材からなる請求項１又は２記載のマスク。The mask according to claim 1, wherein the compression restoration layer is made of a compression restoration material in which a plurality of layers are stacked.

（作用効果）
本項記載のように素材を折り畳んで形成された圧縮復元層はバネのようになるため、厚く、復元性に優れるようになる。また、素材を複数層積み重ねても、先述の折り畳んだ場合よりは復元性は弱まるものの、厚みの点では確保できるので、本発明に適用することができる。 (Function and effect)
Since the compression restoration layer formed by folding the material as described in this section is like a spring, it is thick and has excellent restoration properties. Further, even when a plurality of layers of materials are stacked, the restoration property is weaker than that in the case of folding as described above, but it can be secured in terms of thickness, and therefore can be applied to the present invention.

以上のとおり、本発明によれば、顔面に対するフィット性に優れたマスクとなる。   As described above, according to the present invention, the mask has excellent fit to the face.

以下、本発明の一実施形態について添付図面を参照しながら詳説する。
（第１の実施の形態）
図１〜図３は、立体マスクの第１の実施の形態を示したもので、口及び鼻先を含む顔面の対象部位を覆う本体部１０と、耳に掛け止めるための孔を有する係止部２０とを備えている。図１は接合加工前の展開状態を示したもので、図面の左右方向が横方向、上下方向が縦方向である。本体部１０の上部には谷状の切欠部が形成され、その谷に沿う部分Ｂにおいて、超音波接合や熱溶着により接合され、図３に示すように、口及び鼻先と対向する部分がその周囲部分よりも外側に膨出する立体形状を有する立体マスクとされる。なお、この立体形状は、立体的な寸法関係のみにより形成されるものであり、素材の伸縮やプリーツ等の伸縮構造を要せずに立体となるものである。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
(First embodiment)
1 to 3 show a first embodiment of a three-dimensional mask, a main body portion 10 covering a target portion of a face including a mouth and a nose tip, and a locking portion having a hole for hanging on an ear. 20. FIG. 1 shows an unfolded state before joining, in which the horizontal direction is the horizontal direction and the vertical direction is the vertical direction. A trough-shaped notch is formed in the upper part of the main body 10, and a portion B along the trough is joined by ultrasonic bonding or heat welding, and as shown in FIG. The three-dimensional mask has a three-dimensional shape that bulges outward from the surrounding portion. Note that this three-dimensional shape is formed only by a three-dimensional dimensional relationship, and becomes a three-dimensional shape without requiring a stretchable structure such as expansion / contraction of a material or pleats.

ただし、本発明は立体化手段に限定されるものではない。図示例では、立体マスクとするために、中央部分の上部で縦方向に接合する形態を採ったが、接合部は２以上でもよいし、横方向に接合するようにしてもよい。その他、適宜の方法を採ることができる。   However, the present invention is not limited to the three-dimensional means. In the illustrated example, in order to obtain a three-dimensional mask, the form of joining in the vertical direction at the upper part of the central portion is adopted. However, the number of joining parts may be two or more, or may be joined in the lateral direction. In addition, an appropriate method can be adopted.

本第１の実施形態では、外側層３０により本体部１０及び係止部２０を含むマスク全体形状を形成し、本体部１０の内面側全体を覆うように肌と接触する内側層５０を設け、この内側層５０と外側層３０との間における、鼻の両脇と対向する本体部上縁部に全体にわたり圧縮復元層４０を介在させている。   In the first embodiment, the outer layer 30 forms the entire mask shape including the main body 10 and the locking portion 20, and the inner layer 50 that contacts the skin is provided so as to cover the entire inner surface side of the main body 10. Between the inner layer 50 and the outer layer 30, the compression restoration layer 40 is interposed throughout the upper edge of the main body that faces both sides of the nose.

この圧縮復元層４０を内包する三層構造の部位は適宜定めれば良いが、本体部１０の遮断性を高めるために、周縁部の一箇所、複数箇所または全部に設けることができる。またこの三層構造の部位は、本体部１０の全体としたり、本体部１０のみならず係止部２０の一部（係止部２０の周縁部の一箇所、複数箇所または全部）あるいは全部としたりすることができる。   The portion of the three-layer structure that includes the compression / decompression layer 40 may be determined as appropriate, but may be provided at one, a plurality of, or all of the peripheral portion in order to improve the blocking performance of the main body 10. The three-layer structure may be the entire main body 10, or a part of the locking portion 20 as well as the main body 10 (one, a plurality, or all of the peripheral edge of the locking portion 20) or the entire. Can be.

圧縮復元層４０は、不織布や発泡素材等の圧縮復元性素材により形成することができる。不織布としては、メルトブローン、スパンボンド、エアスルー、ポイントボンド、ニードルパンチ、スパンレース等の製造方法から得られる不織布を用いることができる。また、発泡素材としては、ポリウレタン等を用いることができる。   The compression restoration layer 40 can be formed of a compression restoration material such as a nonwoven fabric or a foam material. As a nonwoven fabric, the nonwoven fabric obtained from manufacturing methods, such as a melt blown, a spun bond, an air through, a point bond, a needle punch, a spun lace, can be used. As the foam material, polyurethane or the like can be used.

圧縮復元層４０の厚さは適宜定めることができるが、好ましくは１〜１０ｍｍであり、さらに好ましくは１．５〜５．０ｍｍである。過度に厚くなると違和感を生じやすく、過度に薄くなると圧縮復元量が少なくなるため、形状追従性に乏しくなる。   Although the thickness of the compression restoration layer 40 can be determined as appropriate, it is preferably 1 to 10 mm, and more preferably 1.5 to 5.0 mm. When the thickness is excessively thick, a sense of incongruity is likely to be generated, and when the thickness is excessively thin, the amount of compression recovery is reduced, resulting in poor shape followability.

圧縮復元層４０の通気度（ＪＩＳ Ｌ １０９６ ８．２７．１ Ａ法）が５０〜４００ｃｃ／ｃｍ2・ｓｅｃであるのが好ましく、特に５０〜３５０ｃｃ／ｃｍ2ｓｅｃであるのが好ましい。通気度が過度に低いと息苦しさを生じ易く、通気度が高すぎると遮断すべきものも透過させてしまうおそれがある。 The air permeability (JIS L 1096 8.27.1 A method) of the compression restoration layer 40 is preferably 50 to 400 cc / cm 2 · sec, and particularly preferably 50 to 350 cc / cm 2 sec. If the air permeability is excessively low, breathing difficulty is likely to occur, and if the air permeability is excessively high, there is a risk of transmitting what should be blocked.

圧縮復元層４０の透湿度（ＪＩＳ−Ｚ−０２０８）は５０〜３００ｇ／ｍ2ｈｒであるのが好ましく、特に１００〜２００ｇ／ｍ2ｈｒであるのが好ましい。透湿度が過度に低いと、マスク内が蒸れ易くなり、通気度が高すぎるとメガネ曇り防止効果が低下する。 Is preferably a moisture permeability of compression recovery layer 40 (JIS-Z-0208) is 50~300g / m 2 hr, it is preferred particularly 100~200g / m 2 hr. If the moisture permeability is too low, the inside of the mask tends to be stuffy, and if the air permeability is too high, the effect of preventing fogging of the glasses decreases.

圧縮復元層４０において、より厚い層を形成するため、素材を複数枚積層することができる。また、より厚い層を形成するだけでなく、より高い圧縮復元性を得るために、図４に示すように、折り畳まれた圧縮復元性素材により圧縮復元層４０を構成することができる。折り畳み回数は特に限定されるものではなく、二つ折でも、三つ折（Ｚ字折）でも、それ以上でも良い。   In order to form a thicker layer in the compression restoration layer 40, a plurality of materials can be laminated. In addition to forming a thicker layer, the compression / decompression layer 40 can be formed of a folded compression / decompression material as shown in FIG. 4 in order to obtain a higher compression / decompression property. The number of times of folding is not particularly limited, and may be two folds, three folds (Z-fold), or more.

圧縮復元層４０の圧縮復元性能は適宜設計すれば良いが、圧縮レジリエンスＲＣが５０％以上、特に６０％以上であるのが好ましい。圧縮復元性が低すぎると、厚さの割に形状追従性、すなわちフィット性に劣るものとなる。   The compression / decompression performance of the compression / decompression layer 40 may be designed as appropriate, but the compression resilience RC is preferably 50% or more, particularly preferably 60% or more. If the compression recovery property is too low, the shape following property, that is, the fitting property is inferior to the thickness.

他方、外側層３０としては、メルトブローン、スパンボンド、エアスルー、ポイントボンド、ニードルパンチ、スパンレース等の製造方法で得られる各種の不織布を好適に用いることができる。また、積層不織布間に極細の糸ゴムを縦横に介在させて、縦及び横方向に伸縮性を付与することもできる。さらに、伸縮性のある不織布を使用することもでき、この具体例としてはポリエーテル系、ポリエステル系、ポリカーボネート系グリコール等をブロック共重合したポリエステル系共重合体、ポリアミド系、ポリウレタン系エラストマー、及びこれらと不織布の積層体などを挙げることができる。伸縮性を有する素材は、係止部２０に用いるのに適しているが、本体部１０に用いることもできる。   On the other hand, as the outer layer 30, various nonwoven fabrics obtained by manufacturing methods such as melt blown, spunbond, air-through, point bond, needle punch, and spunlace can be suitably used. Further, it is also possible to impart stretchability in the vertical and horizontal directions by interposing an extremely fine rubber thread between the laminated nonwoven fabrics in the vertical and horizontal directions. Further, stretchable nonwoven fabrics can also be used. Specific examples thereof include polyester-based copolymers obtained by block copolymerization of polyether-based, polyester-based, polycarbonate-based glycols, polyamide-based, polyurethane-based elastomers, and the like. And a laminate of non-woven fabric. The stretchable material is suitable for use in the locking portion 20, but can also be used in the main body portion 10.

内側層５０としては、メルトブローン、スパンボンド、エアスルー、ポイントボンド、ニードルパンチ、スパンレース等の製造方法で得られる各種の不織布を好適に用いることができる。内側層５０は、通気性であって、肌に刺激を与えない材料が好ましいため、特にメルトブローン不織布が望ましい。内側層５０として化繊混抄紙も用いることができる。化繊混抄紙の具体例としては、ＰＥ／ＰＥＴバイコンポーネント繊維３５％及びパルプ繊維３５％の配合を有するものを挙げることができる。また、内側層５０としては、孔開きプラスチックフィルムを使用して通気性を確保することもできる。孔開きプラスチックフィルムは公知の形成方法によって得ることができる。たとえば、熱可塑性フィルムをパーフォレーションまたは熱プレス等により開孔したフィルム、もしくはこれと不織布とを複合シートとしたものが挙げられる。フィルムの少なくとも内面に親水処理がなされているのが望ましい。親水化処理のための手段に限定はないが、たとえばモノオレフィン酸グリセリンやモノラウリン酸ソルビタンをフィルム内面に塗布するのが望ましい。外面（大気側）も親水処理されていてもよい。   As the inner layer 50, various nonwoven fabrics obtained by manufacturing methods such as melt blown, spun bond, air through, point bond, needle punch, and spun lace can be suitably used. Since the inner layer 50 is preferably a material that is breathable and does not irritate the skin, a meltblown nonwoven fabric is particularly desirable. A synthetic fiber mixed paper can also be used as the inner layer 50. Specific examples of the synthetic fiber mixed paper include those having a blend of 35% PE / PET bicomponent fibers and 35% pulp fibers. Further, as the inner layer 50, a perforated plastic film can be used to ensure air permeability. The perforated plastic film can be obtained by a known forming method. For example, a film obtained by perforating or hot pressing a thermoplastic film, or a composite sheet made of this and a nonwoven fabric can be used. It is desirable that at least the inner surface of the film is subjected to a hydrophilic treatment. The means for hydrophilization treatment is not limited, but it is desirable to apply glyceryl monoolefin or sorbitan monolaurate to the inner surface of the film, for example. The outer surface (atmosphere side) may also be subjected to a hydrophilic treatment.

隣接する各層３０，４０，５０は、超音波接合や熱溶着、接着剤による接着等により接合するのが望ましい。製造に際しては、例えば外側層素材上に圧縮復元層素材及び内側層素材を順に積み重ねて接合した後、上縁、下縁および耳掛け孔等を打ち抜き、さらにその後に横方向中央で折り畳んで谷状切欠部に沿う部分Ｂを接合することができる。   The adjacent layers 30, 40, 50 are desirably bonded by ultrasonic bonding, heat welding, adhesion with an adhesive, or the like. In manufacturing, for example, after compressing layer material and inner layer material are stacked and joined in order on the outer layer material, the upper edge, lower edge and ear hook are punched out, and then folded in the center in the lateral direction to form a valley shape. The part B along the notch can be joined.

（第２の実施の形態）
図５及び図６は、第２の実施形態を示しており、圧縮復元層４０の周囲で内側層５０と外側層３０とを接合してなるものである。この接合部Ｃは、超音波接合や熱溶着、接着剤による接着等により達成できる。この圧縮復元層４０周囲の接合Ｃは、図示のように周方向に連続し環状をなしているのが好ましいが、部分的、例えば点線状であっても良い。要は、圧縮復元層４０が外側層３０及び内側層間に拘束され、不用意に移動しない程度であれば良い。 (Second Embodiment)
5 and 6 show a second embodiment, in which an inner layer 50 and an outer layer 30 are joined around a compression restoration layer 40. FIG. This joint C can be achieved by ultrasonic bonding, thermal welding, adhesion with an adhesive, or the like. The joint C around the compression restoration layer 40 is preferably continuous and circumferential in the circumferential direction as shown in the figure, but may be partially, for example, dotted. In short, it is sufficient that the compression / decompression layer 40 is restrained between the outer layer 30 and the inner layer and does not move carelessly.

また、この圧縮復元層４０周囲の接合Ｃは、図示のように、立体形状とするための接合を兼ねて形成することができる。この場合、立体形状とするための接合を兼ねる接合Ｃについては、他の接合部Ｃとは別工程で接合することができる。   Further, the joint C around the compression / decompression layer 40 can also be formed as a joint for obtaining a three-dimensional shape as shown in the figure. In this case, the joint C that also serves as a joint for obtaining a three-dimensional shape can be joined in a separate process from the other joint C.

本第２の実施形態では、圧縮復元層４０は接合部Ｃにより囲まれ拘束されているため、隣接層３０，５０に対して接合しなくても良く、圧縮復元層４０として熱融着等し難い素材であっても用いることができる利点がある。その他は、第１の実施形態と同様である。   In the second embodiment, since the compression restoration layer 40 is surrounded and restrained by the joint C, the compression restoration layer 40 does not have to be joined to the adjacent layers 30 and 50. There is an advantage that even a difficult material can be used. Others are the same as in the first embodiment.

（第３の実施の形態）

（第４の実施の形態）
図９及び図１０は、第２の実施形態を基本に、圧縮復元層４０を矩形状とし、圧縮復元層４０を取り囲む内側層・外側層間の接合部Ｂを直線状とし、ライン製造における切断、配置及び接合を容易にしたものである。また、圧縮復元層４０周囲の接合Ｃは、立体形状とするための接合Ｂとは別に形成されている。その他は、第２の実施形態と同様である。 (Fourth embodiment)
9 and 10 are based on the second embodiment, the compression restoration layer 40 has a rectangular shape, the joint B between the inner layer and the outer layer surrounding the compression restoration layer 40 has a straight shape, and is cut in line production. It is easy to arrange and join. Further, the joint C around the compression restoration layer 40 is formed separately from the joint B for obtaining a three-dimensional shape. Others are the same as in the second embodiment.

また、図１１及び図１２は、第３の実施形態を基本に、各圧縮復元層を矩形状とし、圧縮復元層を取り囲む内側層・外側層間の接合部を直線状とし、ライン製造における切断、配置及び接合を容易にしたものである。また、圧縮復元層４０周囲の接合Ｃは、立体形状とするための接合Ｂとは別に形成されている。その他は、第３の実施形態と同様である。   11 and 12 are based on the third embodiment, each compression restoration layer is rectangular, the joint between the inner layer and the outer layer surrounding the compression restoration layer is linear, and cutting in line production. It is easy to arrange and join. Further, the joint C around the compression restoration layer 40 is formed separately from the joint B for obtaining a three-dimensional shape. Others are the same as in the third embodiment.

（第５の実施の形態）
図１３及び図１４に示すように、フィット性を高める部分よりも広い範囲に圧縮復元性素材を配置するとともに、この圧縮復元性素材のうちフィット性を高める部分４０を除いて、圧縮状態で且つ復元しない状態に加工する形態も提案される。この加工により、加工部では外側層３０及び内側層５０間に非復元性部分４１（復元性を有しないため圧縮復元層ではない）が形成され、非加工部では外側層３０及び内側層５０間に圧縮復元層部分４０が形成される。 (Fifth embodiment)
As shown in FIG. 13 and FIG. 14, the compression / restorability material is arranged in a wider range than the portion that enhances the fit, and the compression / restorability material is in a compressed state except for the portion 40 that enhances the fit. A form of processing in a state where no restoration is performed is also proposed. By this processing, a non-restorable portion 41 (not a compression decompression layer because it does not have resilience) is formed between the outer layer 30 and the inner layer 50 in the processed portion, and between the outer layer 30 and the inner layer 50 in the non-worked portion. Thus, the compression decompression layer portion 40 is formed.

加工方法としては、素材が熱融着性を有する場合は超音波接合や熱溶着等のように素材を圧縮しつつ加熱する加工方法を利用できるが、素材が熱融着性を有しない場合等、必要に応じて素材を圧縮しつつ接着剤により接着する加工方法を採用することもできる。この加工は、圧縮復元性素材単体の状態で施すことも、また圧縮復元性素材と外側層３０および内側層５０の少なくとも一方とを積層した後の状態で施すことも可能である。   As a processing method, when the material has heat-fusibility, a processing method of heating the material while compressing the material such as ultrasonic bonding or heat welding can be used, but the material does not have heat-fusibility, etc. A processing method in which the material is bonded with an adhesive while compressing the material as necessary can also be adopted. This processing can be performed in the state of the compression-recoverable material alone, or can be performed in a state after the compression-recoverable material and at least one of the outer layer 30 and the inner layer 50 are laminated.

圧縮復元層部分４０及び非復元性部分４１の部位は適宜定めることができる。図示例では、鼻の両脇と対向する本体部上縁部及びその下側部分全体にわたり圧縮復元性素材を配置するとともに、前者の部位には加工を施さずに圧縮復元層部分４０を設け、後者の部位に加工を施し非復元性部分４１を形成している。よって、圧縮復元層４０の形成領域は、第１の実施形態と同様となっている。もちろん、他の部位に圧縮復元層４０を形成したり、複数箇所に圧縮復元層４０を設けたりする場合にも、本形態を適用できる。   The site | parts of the compression decompression | restoration layer part 40 and the non-restorability part 41 can be defined suitably. In the illustrated example, the compression / restoration material is disposed over the entire upper edge of the main body and the lower part thereof facing both sides of the nose, and the compression / restoration layer portion 40 is provided without processing the former part. The latter part is processed to form a non-restorable part 41. Therefore, the formation region of the compression restoration layer 40 is the same as that of the first embodiment. Of course, the present embodiment can also be applied to the case where the compression / decompression layer 40 is formed in another part or the compression / decompression layer 40 is provided in a plurality of places.

（第６の実施の形態）
上記各形態において、図１５に示すように、本体部１０に対して、係止部２０、２０を別部材とすることができる。本体部１０と係止部２０、２０との連結は、接着剤などのほか、好適には超音波接合や熱溶着により接合部Ｄを形成することができる。 (Sixth embodiment)
In each said form, as shown in FIG. 15, the latching | locking parts 20 and 20 can be made into another member with respect to the main-body part 10. As shown in FIG. As for the connection between the main body portion 10 and the locking portions 20, 20, the bonding portion D can be formed by ultrasonic bonding or heat welding in addition to an adhesive or the like.
