　以下、図面を参照しながら、本発明の実施形態を詳説する。なお、各図面において、特に説明がない限り、同一の又は対応する構成については同一の符号を付して説明を省略する場合がある。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each drawing, unless there is a particular description, the same reference numerals may be attached to the same or corresponding configurations, and the description thereof may be omitted.
　（マスクの基本構成）
　本形態におけるマスクは、装着者の顔、より具体的には装着者の少なくとも鼻及び口を覆うことのできるマスクであってよい。本形態によるマスクは、異物が顔に到達することを防止したり、装着者から発生する飛沫が飛散することを防止したりする機能を有し得るものであって、衛生マスク又はサージカルマスクとも呼ばれる。本形態は、使い捨てのマスクとして好適に使用されるが、洗濯等によって繰り返し使用可能なマスクとして使用されてもよい。 (Basic configuration of mask)
The mask in this form may be a mask capable of covering the wearer's face, more specifically at least the nose and mouth of the wearer. The mask according to this embodiment can have the function of preventing foreign substances from reaching the face and preventing droplets generated from the wearer from scattering, and is also called a sanitary mask or a surgical mask. . This form is preferably used as a disposable mask, but may be used as a mask that can be used repeatedly by washing or the like.
　図１に、マスク１の平面図を示す。図１は、マスク１を外面側、すなわち装着時に顔に対向せず外部に露出させる側から見た図である。また、図２に、マスクを内面側（顔側）から見た平面図を示す。図３には、図１のＩ－Ｉ線断面図を示す。 A plan view of the mask 1 is shown in FIG. FIG. 1 is a view of the mask 1 viewed from the outside, that is, the side exposed to the outside without facing the face when worn. Further, FIG. 2 shows a plan view of the mask viewed from the inside (face side). FIG. 3 shows a sectional view taken along line II of FIG.
　図１に示すように、本形態によるマスク１は、装着時に装着者の顔の正面に配置され、装着者の主として鼻及び口を覆うことができるマスク本体１０と、マスク本体１０に結合された一対の耳掛け部材２０ａ、２０ａとを備えている。マスク本体１０は、装着時に装着者の顔の上下方向に対応する縦方向（第１方向）Ｄ１と、縦方向（第１方向）Ｄ１に直交する方向であり、装着時に装着者の顔の左右方向に対応する方向である横方向（第２方向）Ｄ２とを有する。図１の形態では、マスク本体１０は、横方向Ｄ２に長辺を有する長方形の平面視形状を有するが、マスク本体１０の平面視形状は図示のものに限られない。 As shown in FIG. 1, a mask 1 according to the present embodiment includes a mask body 10 that is placed in front of the wearer's face when worn and that can mainly cover the wearer's nose and mouth, and a mask body 10 that is connected to the mask body 10. A pair of ear hook members 20a, 20a is provided. The mask body 10 has a vertical direction (first direction) D1 corresponding to the vertical direction of the wearer's face when worn, and a direction perpendicular to the vertical direction (first direction) D1. and a lateral direction (second direction) D2, which is a direction corresponding to the direction. In the embodiment of FIG. 1, the mask body 10 has a rectangular plan view shape having long sides in the horizontal direction D2, but the plan view shape of the mask body 10 is not limited to that illustrated.
　図１及び図２に示すように、マスク本体１０は、縦方向Ｄ１に並んで配置された複数の襞（プリーツ）によって形成されるプリーツ構造１５を有している。プリーツ構造１５の襞は、マスク本体１０を構成するシートを、横方向Ｄ２に沿った折り線にて複数回折ることによって形成され得る。そして、複数の襞は、マスク本体１０の側部（横方向Ｄ２端部）で固定されている。そのため、マスク１の使用時には、プリーツ構造１５の横方向Ｄ２中央の部分を縦方向Ｄ１に広げることができ、これにより、マスク本体１０の横方向Ｄ２中央が、マスク１の外面側に突出するように湾曲して、顔の立体形状に適合するような形状に変形し得る。プリーツ構造１５の具体的な構成は特に限定されず、マスク本体に形成される公知の構成であってよい。 As shown in FIGS. 1 and 2, the mask body 10 has a pleat structure 15 formed by a plurality of folds (pleats) arranged side by side in the longitudinal direction D1. The folds of the pleated structure 15 can be formed by folding the sheet forming the mask body 10 multiple times along the folding lines along the lateral direction D2. The plurality of folds are fixed at the side portions (horizontal direction D2 end portions) of the mask body 10 . Therefore, when the mask 1 is used, the center portion of the pleat structure 15 in the horizontal direction D2 can be expanded in the vertical direction D1 so that the center of the mask body 10 in the horizontal direction D2 protrudes toward the outer surface of the mask 1. It can be curved and deformed into a shape that conforms to the three-dimensional shape of the face. A specific configuration of the pleat structure 15 is not particularly limited, and may be a known configuration formed on the mask body.
　図１～図３に示すように、一対の耳掛け部材２０ａ、２０ａは、マスク本体１０の外面に配置されている。図１に示すように、耳掛け部材２０ａはそれぞれ、平面視で環状（若しくは閉じた帯状）であってよい。装着時には、耳掛け部材２０ａの環の内側、すなわち耳掛け部材２０ａの中央の開口２９に装着者の耳が入るようにして、耳掛け部材２０ａを耳に掛けることができる。上記環の形状は、特に限定されないが、後述のように四角環状であると好ましい。しかし、環の形状は、円形又は楕円形、三角環状、その他の多角環形状であってもよい。 As shown in FIGS. 1 to 3, the pair of ear hook members 20a, 20a are arranged on the outer surface of the mask body 10. As shown in FIG. As shown in FIG. 1, each of the ear hook members 20a may be annular (or closed strip-shaped) in plan view. When worn, the ear hook member 20a can be hung on the ear such that the ear of the wearer enters the inside of the ring of the ear hook member 20a, that is, the opening 29 in the center of the ear hook member 20a. Although the shape of the ring is not particularly limited, it is preferably a quadrangular ring as described later. However, the shape of the ring may be circular, elliptical, triangular, or other polygonal ring.
　一対の耳掛け部材２０ａ、２０ａは、横方向Ｄ２中央で互いに分離可能に結合した１枚のシート状の耳掛け部材（耳掛け部材シート）２０として構成されていてよい。本明細書において、「シート状」又は「シート」とは、長さ及び幅が厚さに比べて大きく、一平面上に延在する又は延在可能な形状を指す。よって、本形態における一対の耳掛け部材２０ａ、２０ａは、紐状又は糸状の耳掛け部材とは異なっている。一対の耳掛け部材２０ａ、２０ａが耳掛け部材シート２０として構成されていることで、マスク装着時に耳掛け部材２０ａを耳に掛けた時に、耳掛け部材２０ａが耳たぶの裏面に面で接触できるので、耳及び耳の周辺部分に掛かる負担を軽減して、違和感や痛みを低減でき、快適な装着感を得ることができる。 The pair of ear hook members 20a, 20a may be configured as one sheet-like ear hook member (ear hook member sheet) 20 separably coupled to each other at the center in the lateral direction D2. As used herein, the term "sheet-like" or "sheet" refers to a shape whose length and width are greater than its thickness and which extends or can extend in one plane. Therefore, the pair of ear hook members 20a, 20a in this embodiment is different from string-like or thread-like ear hook members. Since the pair of ear hook members 20a, 20a are configured as the ear hook member sheet 20, the ear hook member 20a can come into surface contact with the back surface of the earlobe when the ear hook member 20a is hung on the ear when wearing the mask. , the burden on the ear and the peripheral part of the ear can be reduced, discomfort and pain can be reduced, and a comfortable feeling of wearing can be obtained.
　一対の耳掛け部材２０ａ、２０ａの分離可能な結合部２８の結合形式は特に限定されないが、使用者の通常の力で引っ張ることによって分離可能な結合であることが好ましい。例えば図１に示すように、不連続な切込み（カット部）を入れてミシン目として形成されていてよい。また、結合部２８は、ミシン目ではなく、シートの厚みを小さくすること又はその他の手段によって、一対の耳掛け部材２０ａ、２０ａの境界を脆弱化したり、応力が掛かりやすくしたりすることによっても形成できる。なお、図１に示すように、一対の耳掛け部材２０ａ、２０ａの構成は、結合部２８を通る縦方向Ｄ１に沿った線を対称線とする線対称となっていてよい。 Although there is no particular limitation on the type of connection of the detachable connection portion 28 of the pair of ear hook members 20a, 20a, it is preferable that the connection be separable by the user's normal pulling force. For example, as shown in FIG. 1, discontinuous cuts (cut portions) may be formed as perforations. In addition, the connecting portion 28 can also be formed by reducing the thickness of the sheet or by other means, instead of perforations, weakening the boundary between the pair of ear hook members 20a, 20a and making it easier to apply stress. can be formed. As shown in FIG. 1, the pair of ear hook members 20a, 20a may be symmetrical with respect to a line passing through the coupling portion 28 along the vertical direction D1.
　マスク本体１０は、複数の層が積層されてなる多層構造を有していてよい。例えば、異物（塵、花粉、細菌、ウィルス等）を捕集する機能が高められた中間層を、外側層及び内側層で挟んだ３層を少なくとも含む構造であってよい。マスク本体１０を構成する各層は、不織布、織物、編物等の繊維含有層を含むことが好ましく、不織布を含むことがより好ましい。不織布としては、スパンボンド不織布、スパンレース不織布、メルトブローン不織布、エアスルー不織布、ポイントボンド不織布等が挙げられる。また、中間層には、細い繊維を含み得るメルトブローン不織布が用いられることが好ましい。また、繊維含有層を構成する繊維は樹脂繊維であると好ましく、樹脂繊維の樹脂の種類としては、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ナイロン等が挙げられる。外側層及び内側層の目付は、１５～５０ｇ／ｍ２であってよい。異物捕集性の高い中間層の目付は、１０～１００ｇ／ｍ２であると好ましく、１５～５０ｇ／ｍ２であるとより好ましい。 The mask body 10 may have a multi-layer structure in which a plurality of layers are laminated. For example, it may have a structure including at least three layers in which an intermediate layer having an enhanced function to trap foreign substances (dust, pollen, bacteria, viruses, etc.) is sandwiched between an outer layer and an inner layer. Each layer constituting the mask body 10 preferably includes a fiber-containing layer such as a nonwoven fabric, a woven fabric, or a knitted fabric, and more preferably includes a nonwoven fabric. Examples of nonwoven fabrics include spunbond nonwoven fabrics, spunlace nonwoven fabrics, meltblown nonwoven fabrics, air-through nonwoven fabrics, point-bond nonwoven fabrics, and the like. In addition, it is preferable to use a meltblown nonwoven fabric that can contain fine fibers for the intermediate layer. Moreover, the fibers constituting the fiber-containing layer are preferably resin fibers, and examples of resin types for the resin fibers include polyethylene, polypropylene, polyethylene terephthalate, and nylon. The basis weight of the outer and inner layers may be 15-50 g/m 2 . The basis weight of the intermediate layer having high foreign matter trapping properties is preferably 10 to 100 g/m 2 , more preferably 15 to 50 g/m 2 .
　一対の耳掛け部材２０ａ、２０ａは、マスク本体１０の外面の両側部（横方向Ｄ２の両端部）にそれぞれ結合されている。耳掛け部材２０ａ、２０ａは、伸縮性を有する。本明細書において、「伸縮性を有する」とは、引っ張ること（引張力を加えること）によって引っ張られた方向の長さを大きくすることができ、引っ張ることをやめること（引張力を解除すること）によって、長さが元に戻るか又はほぼ元に戻る性質を有することを指す。さらに、「伸縮性」と言う場合、所定の力で引っ張った場合に材料がどの程度伸びるかという特性、及び／又は所定長さに伸長させた場合に材料にどの程度の引張応力が生じるかという特性を指す。 The pair of ear hook members 20a, 20a are coupled to both side portions (both end portions in the lateral direction D2) of the outer surface of the mask body 10, respectively. The ear hook members 20a, 20a have elasticity. As used herein, the term “stretchable” means that the length in the direction of pulling can be increased by pulling (applying tensile force), and stopping pulling (releasing tensile force) ) refers to having the property of being reversible or nearly reversible in length. Furthermore, the term "elasticity" refers to the property of how much a material stretches when stretched with a given force, and/or how much tensile stress a material experiences when stretched to a given length. refers to characteristics.
　なお、図１～図３に示す例では、一対の耳掛け部材２０ａ、２０ａはそれぞれ、補助材３０、３０を介してマスク本体１０の両側部に結合されている。補助材３０、３０は、マスク１の縦方向Ｄ１に沿って延在するシート状の部材であってよい。そして、補助材３０、３０は、マスク本体１０の横方向Ｄ２の両端部とそれぞれ、外側接合部５０、５０で接合されている。また、補助材３０、３０は、耳掛け部材シート２０の横方向Ｄ２の両端部とそれぞれ、内側接合部６０、６０で接合されている。外側接合部５０、５０、及び内側接合部６０、６０はともに、ヒートシール、超音波シール、接着剤等の接合手段によって接合されていてよい。しかしながら、本形態では、補助材３０とマスク本体１０との外側接合部５０のため、及び補助材３０と耳掛け部材シート２０との内側接合部６０のためにそれぞれ最適な結合形式を選択でき、耳掛け部材シート２０とマスク本体１０とを直接接合させた場合に比べてより堅牢なマスク１が得られる。補助材３０は伸縮性を有していてよいが、耳掛け部材シート２０の伸縮性よりも小さいことが好ましい。 In the example shown in FIGS. 1 to 3, the pair of ear hook members 20a, 20a are connected to both sides of the mask body 10 via auxiliary members 30, 30, respectively. The auxiliary members 30 , 30 may be sheet-like members extending along the longitudinal direction D<b>1 of the mask 1 . The auxiliary members 30, 30 are joined to both ends of the mask body 10 in the horizontal direction D2 at outer joining portions 50, 50, respectively. Further, the auxiliary members 30, 30 are joined to both end portions of the ear hook member sheet 20 in the lateral direction D2 at the inner joining portions 60, 60, respectively. Both the outer joints 50, 50 and the inner joints 60, 60 may be joined together by joining means such as heat sealing, ultrasonic sealing, adhesives, or the like. However, in this embodiment, it is possible to select the optimum joint form for the outer joint 50 between the auxiliary material 30 and the mask body 10 and for the inner joint 60 between the auxiliary material 30 and the ear hook member sheet 20. A stronger mask 1 can be obtained than when the ear hook member sheet 20 and the mask body 10 are directly joined. The auxiliary material 30 may have elasticity, but it is preferable that the elasticity is smaller than that of the ear hook member sheet 20 .
　（マスクの使用方法）
　以下に、図１～図３に示す本形態のマスク１の使用方法について説明する。本形態によるマスク１の使用を開始する際には、使用者は、マスク１の装着前に、一対の耳掛け部材２０ａ、２０ａ同士の分離可能な結合部２８を解除して、耳掛け部材２０ａ、２０ａを互いに分離させる。より具体的には、使用者は、一対の耳掛け部材２０ａ、２０ａをそれぞれの手で摘まんで若しくは把持して、互いに反対方向に引張ることができる。これにより、まず、分離可能な結合部２８の結合を解除できる。その後、耳掛け部材２０ａ、２０ａのマスク本体１０に接合されていない部分を横方向Ｄ２側方へ展開する。その際、使用者は、一対の耳掛け部材２０ａ、２０ａをそれぞれ把持したまま、横方向Ｄ２外方へ（側方へ）それぞれ開くことができる。 (How to use the mask)
A method of using the mask 1 of this embodiment shown in FIGS. 1 to 3 will be described below. When starting to use the mask 1 according to the present embodiment, the user releases the separable connecting portion 28 between the pair of ear hook members 20a, 20a before wearing the mask 1, and the ear hook member 20a , 20a from each other. More specifically, the user can pinch or grip the pair of ear hook members 20a, 20a with each hand and pull them in opposite directions. Thereby, first, the coupling of the separable coupling portion 28 can be released. After that, the portions of the ear hook members 20a, 20a that are not joined to the mask main body 10 are expanded in the lateral direction D2. At this time, the user can open the pair of ear hook members 20a, 20a outward (laterally) in the lateral direction D2 while holding the pair of ear hook members 20a, 20a.
　図４に、図１のマスク１の一対の耳掛け部材２０ａ、２０ａを側方に展開した後の図を示す。また、図５に、図４のＩＩ－ＩＩ線断面図を示す。図４及び図５に示すように、一対の耳掛け部材２０ａ、２０ａを開くと、耳掛け部材２０ａ、２０ａが裏返され、それまでマスク本体１０に対向していた面が露出する。そして、マスク本体１０の外面のほぼ全体も露出する。 FIG. 4 shows a view after the pair of ear hook members 20a, 20a of the mask 1 of FIG. 1 are laterally unfolded. 5 shows a cross-sectional view taken along the line II-II of FIG. As shown in FIGS. 4 and 5, when the pair of ear hook members 20a, 20a is opened, the ear hook members 20a, 20a are turned inside out, and the surface facing the mask body 10 until then is exposed. Almost the entire outer surface of the mask body 10 is also exposed.
　一対の耳掛け部材２０ａ、２０ａは、マスク本体１０の外面側に配置されていても、内面側に配置されていてもよいが、図１～５に示すようにマスク１の外面側に配置されていることが好ましい。一対の耳掛け部材２０ａ、２０ａがマスク本体１０の外面側に配置されていると、一対の耳掛け部材２０ａ、２０ａ同士の分離を解除して横方向Ｄ２外方へ開く際に、マスク本体１０の内面に触れる可能性を低減できるか又はその可能性をなくすことができ、衛生的観点から好ましい。 The pair of ear hook members 20a, 20a may be arranged on the outer surface side or the inner surface side of the mask body 10, but they are arranged on the outer surface side of the mask 1 as shown in FIGS. preferably. When the pair of ear hook members 20a, 20a are arranged on the outer surface side of the mask body 10, when the pair of ear hook members 20a, 20a are released from each other and opened outward in the lateral direction D2, the mask body 10 It is possible to reduce or eliminate the possibility of touching the inner surface of the body, which is preferable from a hygienic point of view.
　本形態によるマスク１は、実際には次のように使用できる。例えば、マスク本体１０の外面を上にしてマスク１が置かれている状態で、使用者が一対の耳掛け部材２０ａ、２０ａをそれぞれ手で把持して横方向Ｄ２外方へ開いた後、一対の耳掛け部材２０ａ、２０ａを把持したままマスク１を他人（装着者）の顔へと移動させることができる。マスク本体１０をその他人の顔の所望の位置へ配置した後、持ち方を変えることなく、一対の耳掛け部材２０ａ、２０ａをそれぞれ、他人の耳に掛けることができる。よって、本形態によるマスク１は、例えば子供、病人等の、マスクを自らで装着することが困難である人にマスクを装着させる場合に、好適に使用することができる。 The mask 1 according to this embodiment can actually be used as follows. For example, in a state in which the mask 1 is placed with the outer surface of the mask body 10 facing up, the user holds the pair of ear hook members 20a, 20a by hand and opens them outward in the lateral direction D2. The mask 1 can be moved to the face of another person (wearer) while holding the ear hook members 20a, 20a. After arranging the mask body 10 at a desired position on the other person's face, the pair of ear hook members 20a, 20a can be hung on the other person's ears without changing the way of holding the mask. Therefore, the mask 1 according to the present embodiment can be suitably used when a person, such as a child or a sick person, who has difficulty in wearing a mask by himself/herself is made to wear the mask.
　さらに、図１に示すように、一対の耳掛け部材２０ａ、２０ａには、一対の耳掛け部材２０ａ、２０ａを互いに分離して横方向Ｄ２外方に開く際に使用者が摘まむことができる摘み部２５、２５が形成されていてよい。摘み部２５、２５は、平面視でマスク本体１０の端縁から、好ましくはマスク１の下端（又はマスク本体１０の下端）から突出していると好ましい。摘み部２５、２５がマスク本体１０の端縁から突出していることで、マスク本体１０自体に、すなわちマスク本体１０の外面及び内面のどちらにも触れずに又はほとんど触れずに、使用者が両手で摘み部２５、２５を摘まむこともできる。そして、使用者は、マスク本体１０に触れずに又はほとんど触れずに一対の耳掛け部材２０ａ、２０ａを分離・展開させることができる。よって、使用者が手指の衛生に十分な配慮ができない状況であっても、良好な衛生状態のマスク１を自らに又は他人に装着できる。なお、摘み部２５がマスク本体１０の端縁から突出している場合、突出した部分の縦方向Ｄ１の最大の長さは、５～２０ｍｍであると好ましく、８～１５ｍｍであるとさらに好ましい。 Furthermore, as shown in FIG. 1, the pair of ear hook members 20a, 20a can be pinched by the user when the pair of ear hook members 20a, 20a are separated from each other and opened outward in the lateral direction D2. Knobs 25, 25 may be formed. The knobs 25, 25 preferably protrude from the edge of the mask body 10, preferably from the lower end of the mask 1 (or the lower end of the mask body 10) in plan view. Since the knobs 25, 25 protrude from the edge of the mask body 10, the user can use both hands without or almost without touching the mask body 10 itself, i.e., neither the outer surface nor the inner surface of the mask body 10. The knobs 25, 25 can also be pinched with. Then, the user can separate and deploy the pair of ear hook members 20a, 20a without touching the mask body 10 or almost without touching it. Therefore, even in a situation where the user cannot give sufficient consideration to hand hygiene, the user can wear the mask 1 in good hygiene on himself or others. When the knob portion 25 protrudes from the edge of the mask body 10, the maximum length of the protruding portion in the vertical direction D1 is preferably 5 to 20 mm, more preferably 8 to 15 mm.
　また、耳掛け部材２０ａが摘み部２５、２５を有することで、使用者は、耳掛け部材２０ａを装着者の耳に掛ける時又は掛けた後に、摘み部２５、２５を持って耳掛け部の調整を容易に行うこともできる。すなわち、摘み部２５、２５を持って、耳掛け部材２０ａを、耳に対して相対的に耳掛け部材２０ａの周方向にずらして位置調整を行うこと、或いは耳掛け部材２０ａを後側に向かって引っ張ったり緩めたりして耳掛け部材２０ａの張り具合を調整することが可能である。 In addition, since the ear hook member 20a has the knobs 25, 25, the user can hold the knobs 25, 25 to open the ear hook when or after putting the ear hook member 20a on the wearer's ear. Adjustments can also be made easily. That is, by holding the knobs 25, 25, the position of the ear hook member 20a can be adjusted by shifting the ear hook member 20a relative to the ear in the circumferential direction of the ear hook member 20a, or by moving the ear hook member 20a toward the rear side. It is possible to adjust the tension of the ear hook member 20a by pulling or loosening it.
　さらに、一対の耳掛け部材２０ａ、２０ａがマスク本体１０の内面（顔側の面）でなく、外面の両側部にそれぞれ結合されていることにより、マスク１の装着時、すなわち耳掛け部材２０ａ、２０ａを側方に開いて耳に掛けている状態では（図４及び図５）、マスク本体１０の両側部は、耳掛け部材２０ａによって外面側から顔に向かって押さえられる。これにより、マスク本体１０の両側部においてマスク本体１０と顔との隙間を小さくすることができ、マスクの機能、例えば異物を遮断する機能、装着者が発した飛沫を飛散させない機能等を向上できる。また、本体の両側部の内面側（顔側）に耳掛け部材２０ａが配置されていないことで、装着中に、マスク本体１０の両側部において耳掛け部材２０ａが装着者の顔に直接接触しないため、違和感も低減される。 Furthermore, since the pair of ear hook members 20a, 20a are connected to both sides of the outer surface of the mask body 10 instead of the inner surface (face-side surface) of the mask body 10, when the mask 1 is worn, that is, the ear hook members 20a, 20a When the mask 20a is opened to the sides and hung on the ear (FIGS. 4 and 5), both sides of the mask body 10 are pressed toward the face from the outside by the ear hooking members 20a. As a result, the gap between the mask body 10 and the face can be reduced on both sides of the mask body 10, and the functions of the mask, such as the function of blocking foreign matter and the function of preventing droplets emitted by the wearer from scattering, can be improved. . In addition, since the ear hook members 20a are not arranged on the inner surface side (face side) of both sides of the main body, the ear hook members 20a on both sides of the mask body 10 do not come into direct contact with the wearer's face during wearing. Therefore, discomfort is also reduced.
　なお、マスク本体１０には、マスク本体１０の外面及び内面の区別を可能にするマーク１８を、エンボス加工、印刷、縫込み等によって形成してもよい。マーク１８は、使用者が目視で認識できるものであれば、その形態は限定されない。マーク１８は、図１等に示すように、文字であってもよいし、数字、記号、図形、ロゴ等であってもよい。 Note that the mask body 10 may be formed with a mark 18 that enables distinction between the outer surface and the inner surface of the mask body 10 by embossing, printing, sewing, or the like. The form of the mark 18 is not limited as long as it can be visually recognized by the user. The marks 18 may be letters, numbers, symbols, graphics, logos, etc., as shown in FIG.
　（耳掛け部材）
　図６に、図１のマスク１のうち、一対の耳掛け部材２０ａ、２０ａ（耳掛け部材シート２０）のみを示す。上述のように、耳掛け部材２０ａ（又は耳掛け部材シート２０）は伸縮性を有するが、この耳掛け部材２０ａの伸縮性は、図６に示すように、環状シート状の耳掛け部材２０ａの全体にわたって、縦方向Ｄ１に離間して配置された複数の伸縮性紐材９、９、…によって得られている。複数の伸縮性紐材９、９、…はそれぞれ横方向Ｄ２に沿って延在しており、これにより、耳掛け部材２０ａの横方向Ｄ２の伸縮性を得ることができる。伸縮性紐材９、９、…の延在方向は、横方向Ｄ２に対して平行であることが好ましいが、横方向Ｄ２に対して略平行、すなわち横方向Ｄ２に対して±１０°程度、好ましくは±５°程度傾斜した方向であってよい。また、伸縮性紐材９、９、…の縦方向Ｄ１での配置間隔Ｌ（ピッチ）は、１～１０ｍｍ程度であってよい。 (Ear hook member)
FIG. 6 shows only a pair of ear hook members 20a, 20a (ear hook member sheet 20) of the mask 1 of FIG. As described above, the ear hook member 20a (or the ear hook member sheet 20) has elasticity. It is obtained by a plurality of elastic cord members 9, 9, . . . spaced apart in the longitudinal direction D1 throughout. Each of the plurality of stretchable string members 9, 9, . . . extends along the lateral direction D2, whereby the stretchability of the ear hook member 20a in the lateral direction D2 can be obtained. The extending directions of the elastic cord members 9, 9, . . . are preferably parallel to the lateral direction D2. Preferably, the direction may be inclined by about ±5°. In addition, the arrangement interval L (pitch) of the elastic cord members 9, 9, . . . in the longitudinal direction D1 may be about 1 to 10 mm.
　伸縮性紐材９は、例えば紐状又は糸状の弾性材料（糸ゴム等）であってよい。伸縮性紐材９の太さは、好ましくは２００～１，５００ｄｔｅｘ、より好ましくは４００～１，０００ｄｔｅｘであってよい。また、伸縮性紐材９の断面の形状は円形であってよいが、楕円、正方形、長方形等の四角形、その他の多角形であってもよい。また、なお、伸縮性紐材９としては、伸長引張試験機によって測定される最大伸長率が自然長の１５０％～１，０００％となるような材料を用いることができる。 The stretchable string material 9 may be, for example, a string-like or thread-like elastic material (rubber thread, etc.). The thickness of the elastic string material 9 may preferably be 200 to 1,500 dtex, more preferably 400 to 1,000 dtex. In addition, the cross-sectional shape of the stretchable string material 9 may be circular, but may be elliptical, square, quadrangular such as rectangular, or other polygonal. In addition, as the stretchable cord material 9, a material having a maximum elongation rate measured by an elongation tensile tester of 150% to 1,000% of the natural length can be used.
　図７に、図６のＩＩＩ－ＩＩＩ線断面の部分拡大図を、図８に、図６のＩＶ－ＩＶ線断面（伸縮性紐材９の中心線を通る断面図）の部分拡大図を示す。図８（ａ）には、伸縮性紐材９が外力Ｔ、Ｔによって横方向Ｄ２外方に引っ張られている状態、図８（ｂ）には、外力が掛かっていない状態（自然状態）を示す。なお、図８（ａ）は、耳掛け部材２０ａの製造工程において、伸縮性紐材９が伸長状態で第１表面材２と第２表面材３とに接着された状態を示す図でもある。また、図８（ｂ）は、製造工程において、図８（ａ）に示す状態から、伸縮性紐材９の伸長を解除した（伸縮性紐材９の引張りをやめた）後の状態も示す。 7 shows a partially enlarged view of the III-III line cross section of FIG. 6, and FIG. 8 shows a partially enlarged view of the IV-IV line cross section of FIG. . FIG. 8(a) shows a state in which the elastic cord material 9 is pulled outward in the lateral direction D2 by external forces T, T, and FIG. 8(b) shows a state in which no external force is applied (natural state). show. FIG. 8A also shows a state in which the stretchable string member 9 is adhered to the first surface member 2 and the second surface member 3 in a stretched state in the manufacturing process of the ear hook member 20a. FIG. 8(b) also shows the state after the stretching of the elastic cord member 9 is released (pulling of the elastic cord member 9 is stopped) from the state shown in FIG. 8(a) in the manufacturing process.
　耳掛け部材２０ａ（耳掛け部材シート２０）の製造をより具体的に説明すると、伸縮性紐材９、９、…を所定の伸長率で伸長させた状態で、伸縮性紐材９の一方の側に第１表面材２を配置し、他方の側に第２表面材３を配置し、伸縮性紐材９を第１表面材２及び第２表面材３のそれぞれに、接着部６、６、…で間欠的に接着させる（図８（ａ））。ここで、所定の伸長率（自然状態の長さＬｎに対する伸長状態の長さＬｅ、すなわちＬｅ／Ｌｎ×１００（％））は、好ましくは１００～４００％、より好ましくは１５０～３００％であってよい。伸縮性紐材９と表面材２、３との接着は、接着剤、縫込み等によって形成できる。また、伸縮性紐材９が配置されていない部分においては、第１表面材２と第２表面材３とが直接接合されていてよい。 More specifically, the production of the ear hook member 20a (the ear hook member sheet 20) will be described. The first surface material 2 is arranged on one side, and the second surface material 3 is arranged on the other side. , . . . intermittently (FIG. 8(a)). Here, the predetermined elongation rate (length Le in the elongated state with respect to the length Ln in the natural state, that is, Le/Ln×100 (%)) is preferably 100 to 400%, more preferably 150 to 300%. you can The adhesion between the stretchable string material 9 and the surface materials 2 and 3 can be formed by an adhesive, stitching, or the like. In addition, the first surface material 2 and the second surface material 3 may be directly joined in the portion where the stretchable cord material 9 is not arranged.
　上述の伸縮性紐材９と表面材２、３との接着後、伸縮性紐材９の伸長を解いて伸縮性紐材９を自然状態にすると、第１表面材２及び第２表面材３には柔軟性の高い材料が使用されているため、第１表面材２及び第２表面材３の、接着部６、６、…以外の部分は、伸縮性紐材９から離れる方向に盛り上がり、耳掛け部材２０ａには、縦方向Ｄ１に沿って延在する小さな皺が横方向Ｄ２に複数並んで形成される（図８（ｂ））。このような複数の皺（ギャザー）を有する伸縮性シート状体の構成は、公知の伸縮性ギャザーと同様に形成することができる。耳掛け部材２０ａの実際の製造においては、複数の伸縮性紐材９、９、…が第１表面材２及び第２表面材３に挟まれてなる接合体が形成された後、一対の耳掛け部材２０ａ、２０ａの形状に打ち抜くことができる。 After the elastic cord member 9 and the surface members 2 and 3 are adhered to each other, the elastic cord member 9 is unstretched to restore the elastic cord member 9 to its natural state, whereby the first surface member 2 and the second surface member 3 Since a highly flexible material is used for , the portions of the first surface material 2 and the second surface material 3 other than the bonded portions 6 , 6 , . . . A plurality of small wrinkles extending in the longitudinal direction D1 are formed in the lateral direction D2 on the ear hook member 20a (FIG. 8(b)). Such a stretchable sheet-like body having a plurality of wrinkles (gathers) can be formed in the same manner as known stretchable gathers. In the actual manufacture of the ear hook member 20a, after a joined body is formed by sandwiching a plurality of elastic cord members 9, 9, . . . The hanging members 20a, 20a can be punched out.
　耳掛け部材２０ａの表面に上述のような多数の皺が形成されていることで、耳掛け部材２０ａの表面が肌に接した時、耳掛け部材２０ａの素材が肌の全面に接触するのではなく、耳掛け部材２０ａと肌との間に空間が形成されるので、肌にべったり張り付くような感覚を低減でき、装着感を向上させることができる。 Since many wrinkles are formed on the surface of the ear hook member 20a as described above, when the surface of the ear hook member 20a contacts the skin, the material of the ear hook member 20a may contact the entire surface of the skin. Since a space is formed between the ear hook member 20a and the skin, it is possible to reduce the feeling of sticking to the skin and improve the wearing comfort.
　第１表面材２及び第２表面材３は柔軟性を有する材料であればよく、同じであってもよいし、異なっていてもよい。また、第１表面材２及び第２表面材３は、繊維構造体であると好ましい。繊維構造体としては、不織布、織物、編物等が挙げられ、このうち不織布は、肌触り、通気性が良く、装着感の向上に寄与するため、好ましい。不織布としては、エアスルー不織布、スパンボンド不織布、スパンレース不織布、ニードルパンチ不織布、ケミカルボンド不織布等が挙げられる。このうち、毛羽立ちがなく、強度の高いスパンボンド不織布、柔らかさのあるエアスルー不織布等が好ましい。また、不織布に含まれる繊維は樹脂繊維であってよく、樹脂繊維の樹脂の種類として、ポリエチレン、ポリプロピレン、ポリエチレンテレフタレート、ナイロン等が挙げられる。第１表面材２又は第２表面材３が不織布である場合、不織布の目付は、好ましくは５～５０ｇ／ｍ２、より好ましくは８～２５ｇ／ｍ２であってよい。 The first surface material 2 and the second surface material 3 may be materials having flexibility, and may be the same or different. Moreover, the 1st surface material 2 and the 2nd surface material 3 are preferable in it being a fiber structure. Examples of the fiber structure include nonwoven fabrics, woven fabrics, knitted fabrics, etc. Among these, nonwoven fabrics are preferable because they have good touch and breathability and contribute to improvement of wearing comfort. Nonwoven fabrics include air-through nonwoven fabrics, spunbond nonwoven fabrics, spunlace nonwoven fabrics, needle-punched nonwoven fabrics, chemical-bonded nonwoven fabrics, and the like. Among these, spunbonded nonwoven fabrics having no fluff and high strength, air-through nonwoven fabrics having softness, and the like are preferable. Also, the fibers contained in the nonwoven fabric may be resin fibers, and examples of resin types for the resin fibers include polyethylene, polypropylene, polyethylene terephthalate, and nylon. When the first surface material 2 or the second surface material 3 is a nonwoven fabric, the nonwoven fabric preferably has a basis weight of 5 to 50 g/m 2 , more preferably 8 to 25 g/m 2 .
　このように、本形態による耳掛け部材２０ａは、複数の伸縮性紐材９、９、…を用いて構成された伸縮性の部材である。そのため、伸縮性紐材９の伸縮性、すなわち所定の力で引っ張った場合に紐材がどの程度伸びるか、或いは所定長さに伸長させた場合に紐材にどの程度の引張応力が生じるかは、伸縮性紐材９の太さや材質を変更することで、容易に、また広範に調整できる。そのため、本形態による耳掛け部材２０ａの伸縮性の調整は、伸縮性不織布等を用いて構成された耳掛け部材と比べて、耳掛け部材２０ａ又は耳掛け部材シート２０の伸縮性の調整が容易である。よって、使用前の状態（自然状態）では短いが、マスク１装着時には長い長さを確保できる耳掛け部材２０ａが望まれている場合、例えば、伸縮性紐材９、９、…の製造時の伸長率（表面材に接着する時の伸縮性紐材の自然状態長さに対する長さ）を大きくすることで、引張り時に長く伸ばすことができる耳掛け部材２０ａを得ることができる。また、マスク本体１０を顔により密着させたい場合には、例えば、太さの太い（ｄｔｅｘ数の大きい）伸縮性紐材９、９、…を用いることで、耳掛け部材２０ａを引っ張った際により大きな引張応力が生じるようにでき、耳掛け部材２０ａ、２０ａがマスク本体１０を所定位置に押さえる機能を向上させることができる。また、伸縮性紐状９を特にゴム等の弾性素材で形成した場合には、伸縮性不織布等と比較して、顕著な伸縮性を実現できる。 Thus, the ear hook member 20a according to this embodiment is a stretchable member configured using a plurality of stretchable string members 9, 9, . Therefore, the stretchability of the elastic cord material 9, that is, how much the cord material stretches when it is pulled with a predetermined force, or how much tensile stress is generated in the cord material when it is stretched to a predetermined length is determined. By changing the thickness and material of the elastic string material 9, it can be easily and extensively adjusted. Therefore, adjustment of the stretchability of the ear hook member 20a according to this embodiment is easier than adjustment of the stretchability of the ear hook member 20a or the ear hook member sheet 20 compared to an ear hook member configured using a stretchable nonwoven fabric or the like. is. Therefore, when it is desired to have an ear hook member 20a that is short in the state before use (natural state) but long enough when wearing the mask 1, for example, when the elastic cord members 9, 9, By increasing the elongation rate (the length of the stretchable cord material relative to the natural length when adhered to the surface material), it is possible to obtain the ear hook member 20a that can be stretched long when pulled. In addition, when the mask body 10 is desired to be in closer contact with the face, for example, by using elastic cord members 9, 9, . A large tensile stress can be generated, and the function of the ear hook members 20a, 20a to hold the mask body 10 in place can be improved. In addition, when the stretchable string 9 is made of an elastic material such as rubber, a remarkable stretchability can be realized as compared with a stretchable nonwoven fabric or the like.
　さらに、耳掛け部材２０ａ、２０ａ（耳掛け部材シート２０）における複数の伸縮性紐材９、９、…の構成は、耳掛け部材２０ａ、２０ａ（耳掛け部材シート２０）全体にわたって同じであってもよいし、耳掛け部材２０ａ、２０ａ（耳掛け部材シート２０）の領域によって部分的に異ならせてもよい（後述）。その場合、例えば縦方向Ｄ１で見て、上方、中央、下方の領域で、伸縮性紐材９、９、…の太さ、製造時の伸長率、配置（間隔）等を異ならせてもよい。 Furthermore, the configuration of the plurality of elastic cord members 9, 9, ... in the ear hook members 20a, 20a (ear hook member sheet 20) is the same throughout the ear hook members 20a, 20a (ear hook member sheet 20). Alternatively, the regions of the ear hook members 20a, 20a (ear hook member sheet 20) may be partially different (described later). In that case, for example, when viewed in the vertical direction D1, the thickness of the elastic cord members 9, 9, . . . .
　本形態による耳掛け部材２０ａは環状であり、好ましくは、図６に示すような四角環状、好ましくは矩形環状であってよい。四角環状は、環の周方向に沿って見た時、方向が大きく変わる位置が４つ認識される形状である。図６に示すように、１つの四角環状の耳掛け部材２０ａは、四角環の上辺に対応する上辺部２３、及び四角環の下辺に対応する下辺部２６を有していてよい。上辺部２３及び下辺部２６は、装着時に、主としてマスク本体１０から耳へと横方向Ｄ２に伸ばされる部分である。さらに、耳掛け部材２０ａは、装着時に装着者の耳の後方に接して配置される耳後方配置部２４と、その大部分がマスク本体１０に接合される基部２２とを有していてよい。耳後方配置部２４は、耳掛け部材シート２０における横方向Ｄ２の中央側で、上辺部２３と下辺部２６との間に縦方向Ｄ１に沿って延在する部分であり、基部２２は、耳掛け部材シート２０における横方向Ｄ２の端部側で、上辺部２３と下辺部２６との間に縦方向Ｄ１に沿って延在する部分である。 The ear hook member 20a according to this embodiment is annular, preferably square annular as shown in FIG. 6, preferably rectangular annular. A quadrangular ring is a shape that can be recognized at four positions where the direction changes greatly when viewed along the circumferential direction of the ring. As shown in FIG. 6, one square ring-shaped ear hook member 20a may have an upper side portion 23 corresponding to the upper side of the square ring and a lower side portion 26 corresponding to the lower side of the square ring. The upper side portion 23 and the lower side portion 26 are portions that are mainly extended in the lateral direction D2 from the mask main body 10 to the ears when worn. Furthermore, the ear hook member 20a may have a behind-the-ear placement portion 24 that is arranged in contact with the back of the wearer's ear when worn, and a base portion 22, most of which is joined to the mask body 10. As shown in FIG. The ear rear portion 24 is a portion extending along the vertical direction D1 between the upper side portion 23 and the lower side portion 26 on the center side of the ear hook member sheet 20 in the horizontal direction D2. It is a portion extending along the vertical direction D1 between the upper side portion 23 and the lower side portion 26 on the end side of the hanging member sheet 20 in the horizontal direction D2.
　そして、図６に示すように、耳掛け部材２０ａは、縦方向Ｄ１で見て、上辺部２３に対応する上端部領域Ｅ１と、下辺部２６に対応する下端部領域Ｅ２と、上端部領域Ｅ１と下端部領域Ｅ２との間の中央領域Ｍを有していてよい。図６に示すような耳掛け部材２０ａの形状の場合、より具体的には、四角環の内周縁においては、曲率半径が極小となる４つの点（ｐ１、ｐ２、ｐ１’、ｐ２’）があるので、そのうちの中央寄りにある２つの点（ｐ１、ｐ２）をそれぞれ通る横方向Ｄ２に平行な直線を引いた場合、その直線間の領域を中央領域Ｍとすることができる。すなわち、上側の第１点ｐ１を通る横方向Ｄ２に平行な直線を、上端部領域Ｅ１と中央領域Ｍとの境界線とし、下側の第２点ｐ２を通る横方向Ｄ２に平行な直線を、下端部領域Ｅ２と中央領域Ｍとの境界線とすることができる。 As shown in FIG. 6, the ear hook member 20a has an upper end region E1 corresponding to the upper side portion 23, a lower end region E2 corresponding to the lower side portion 26, and an upper end region E1 when viewed in the vertical direction D1. and the bottom region E2. In the case of the shape of the ear hook member 20a as shown in FIG. 6, more specifically, four points (p1, p2, p1', p2') where the radius of curvature is minimal on the inner peripheral edge of the square ring. Therefore, when straight lines are drawn in parallel with the horizontal direction D2 passing through two points (p1, p2) near the center of them, the area between the straight lines can be defined as the central area M. That is, a straight line parallel to the horizontal direction D2 passing through the upper first point p1 is defined as the boundary between the upper end region E1 and the central region M, and a straight line parallel to the horizontal direction D2 passing through the lower second point p2 is defined as , a boundary line between the lower end region E2 and the central region M. FIG.
　（耳掛け部材の変形例）
　図９に、変形例による耳掛け部材２０ａＡ、２０ａＡ（耳掛け部材シート２０Ａ）を示す。図９に示す耳掛け部材２０ａＡの基本的な構成は、図６～８を参照して説明した耳掛け部材２０ａと同様であるが、耳掛け部材２０ａＡにおいては、上端部領域Ｅ１及び下端部領域Ｅ２で使用されている伸縮性紐材９ｔ、９ｔ、…の太さが、中央領域Ｍで使用されている伸縮性紐材９、９、…の太さより大きくなっている。例えば、中央領域Ｍにおける伸縮性紐材９、９、…の太さＤＭ（ｄｔｅｘ）対する、上端部領域Ｅ１及び／又は下端部領域Ｅ２における伸縮性紐材９ｔ、９ｔ、…の太さＤＥ（ｄｔｅｘ）の比の値（ＤＥ／ＤＭ）は、好ましくは１．１～３とすることができる。また、中央領域Ｍにおける伸縮性紐材９、９、…の太さＤＭは２００～９００ｄｔｅｘ、上端部領域Ｅ１及び／又は下端部領域Ｅ２における伸縮性紐材９ｔ、９ｔ、…の太さＤＥは２２０～１，２００ｄｔｅｘであってよい。 (Modified example of ear hanging member)
FIG. 9 shows ear hooking members 20aA, 20aA (ear hooking member sheet 20A) according to a modified example. The basic configuration of the ear hook member 20aA shown in FIG. 9 is the same as the ear hook member 20a described with reference to FIGS. The thickness of the elastic cord members 9t, 9t, . . . used in E2 is larger than the thickness of the elastic cord members 9, 9, . For example, the thickness D M (dtex) of the elastic cord members 9, 9, . . . The ratio value of E (dtex) (D E /D M ) can be preferably 1.1-3. Further, the thickness D M of the elastic cord members 9, 9, ... in the central region M is 200 to 900 dtex, and the thickness D of the elastic cord members 9t, 9t, ... in the upper end region E1 and/or the lower end region E2. E can be from 220 to 1,200 dtex.
　図９に示す耳掛け部材２０ａＡを横方向Ｄ２に引っ張った場合、上端部領域Ｅ１及び下端部領域Ｅ２では、中央領域Ｍよりも大きな引張応力が横方向Ｄ２で発生することになる。ここで、上端部領域Ｅ１及び下端部領域Ｅ２は、装着時に横方向Ｄ２に大きく引っ張られる上辺部２３及び下辺部２６にそれぞれ対応している。上辺部２３及び下辺部２６における引張応力が大きいと、上辺部２３及び下辺部２６がマスク本体１０をより大きな力で引っ張ることができるので、マスク本体を顔の方向により強く抑えることができ、マスク本体を顔により密着させることができる。一方、中央領域Ｍでは、横方向Ｄ２にもある程度の伸縮性があることが好ましいが、伸縮性紐材９、９、…の太さが細い方が、耳後方配置部２４を柔軟にでき、耳後方配置部２４が耳の後方の肌に触れた際の違和感を低減できる。よって、図９に示す例によれば、マスクのフィット性、及び耳周りの快適さを求める装着者に好適な耳掛け部材、及びマスクを提供できる。 When the ear hook member 20aA shown in FIG. 9 is pulled in the lateral direction D2, a greater tensile stress is generated in the lateral direction D2 than in the central region M in the upper end region E1 and the lower end region E2. Here, the upper end region E1 and the lower end region E2 respectively correspond to the upper side portion 23 and the lower side portion 26 that are largely pulled in the lateral direction D2 during mounting. If the tensile stress in the upper side portion 23 and the lower side portion 26 is large, the upper side portion 23 and the lower side portion 26 can pull the mask body 10 with a greater force, so that the mask body can be held down more strongly in the direction of the face. The body can be brought into closer contact with the face. On the other hand, in the central region M, it is preferable that there is some degree of elasticity in the lateral direction D2, but the thickness of the elastic cord members 9, 9, . . . It is possible to reduce discomfort when the behind-the-ear placement part 24 touches the skin behind the ear. Therefore, according to the example shown in FIG. 9, it is possible to provide an ear hook member and a mask that are suitable for a wearer who seeks fit of the mask and comfort around the ears.
　図１０に、別の変形例による耳掛け部材２０ａＢ、２０ａＢ（耳掛け部材シート２０Ｂ）を示す。図１０に示す耳掛け部材２０ａＢの基本的な構成は、図６～８を参照して説明した耳掛け部材２０ａと同様であるが、耳掛け部材２０ａＢにおいては、上端部領域Ｅ１及び下端部領域Ｅ２で使用されている伸縮性紐材９ｓ、９ｓ、…の伸長率が、中央領域Ｍで使用されている伸縮性紐材９、９、…の伸長率より大きくなっている。例えば、中央領域Ｍにおける伸縮性紐材９、９、…の伸長率ＲＭ（％）に対する、上端部領域Ｅ１及び／又は下端部領域Ｅ２における伸縮性紐材９ｓ、９ｓ、…の伸長率ＲＥ（％）の比の値（ＲＥ／ＲＭ）は、好ましくは１．１～２とすることができる。また、中央領域Ｍにおける伸縮性紐材９、９、…の伸長率ＲＭは１００～３００％、上端部領域Ｅ１及び／又は下端部領域Ｅ２における伸縮性紐材９ｓ、９ｓ、…の伸長率ＲＥは１１０～４００％であってよい。 FIG. 10 shows ear hooking members 20aB, 20aB (ear hooking member sheet 20B) according to another modification. The basic configuration of the ear hook member 20aB shown in FIG. 10 is similar to the ear hook member 20a described with reference to FIGS. The stretch rate of the stretchable cord members 9s, 9s, . . . For example, the elongation rate R of the elastic cords 9s, 9s, ... in the upper end region E1 and/or the lower end region E2 with respect to the elongation rate R M (%) of the elastic cords 9, 9, ... in the central region M The E (%) ratio value (R E /R M ) can preferably be 1.1-2. Further, the elongation rate RM of the elastic cord members 9, 9, ... in the central region M is 100 to 300%, and the elongation rate of the elastic cord members 9s, 9s, ... in the upper end region E1 and/or the lower end region E2. RE may be 110-400 %.
　上端部領域Ｅ１及び下端部領域Ｅ２において伸縮性紐材９、９、…の伸長率が高いということは、それらの領域を引張った時の最大長さが長いということである。よって、上端部領域Ｅ１及び下端部領域Ｅ２にそれぞれ対応する上辺部２３及び下辺部２６を大きく引き伸ばすことができるので、引張り力を受ける前の状態では横方向Ｄ２の長さが短くとも、装着時には長さを長く、マスク本体から耳までの距離が長い場合にも対応できる耳掛け部材が得られる。一方、中央領域Ｍに対応する耳後方配置部２４にも、自然な変形ができるようある程度の伸縮性があることが好ましいが、伸長率が過度に大きくない方が、横方向Ｄ２長さが当たりの表面材の皺が過度に密に形成されない又は厚く形成されないため、耳に当たった時の感触が向上する。よって、中央領域Ｍにおける伸縮性紐材９、９、…の伸長率が比較的低いことで、耳周りでの感触が快適になる。なお、図１０には、第１表面材２の縦方向Ｄ１に延びる皺の例を模式的に図示する。図１０に示すように、上端部領域Ｅ１及び下端部領域Ｅ２においては表面材の皺同士の横方向Ｄ２のピッチは小さく、皺が密集して形成されている一方、中央領域Ｍにおいては表面材の皺同士の横方向Ｄ２のピッチはより大きく、皺が疎らに形成されている。よって、図１０に示す例では、マスク本体の横方向Ｄ２の端部から耳までの長さが長い条件、及び耳周りの快適さを求める装着者に好適なマスクを提供できる。 The high elongation rate of the elastic cord members 9, 9, ... in the upper end region E1 and the lower end region E2 means that the maximum length when these regions are pulled is long. Therefore, the upper side portion 23 and the lower side portion 26 corresponding to the upper end region E1 and the lower end region E2, respectively, can be greatly stretched. To obtain an ear hook member which is long and can be used even when the distance from the mask body to the ear is long. On the other hand, it is preferable that the ear rear portion 24 corresponding to the central region M also has a certain degree of elasticity so that it can be naturally deformed. Since the wrinkles of the surface material are not formed too densely or thickly, the feeling when hitting the ear is improved. Therefore, the elastic cord members 9, 9, . In addition, FIG. 10 schematically illustrates an example of wrinkles extending in the longitudinal direction D1 of the first surface material 2 . As shown in FIG. 10, in the upper end region E1 and the lower end region E2, the pitch of the wrinkles of the surface material in the lateral direction D2 is small, and the wrinkles are densely formed. The pitch of the wrinkles in the lateral direction D2 is larger, and the wrinkles are sparsely formed. Therefore, in the example shown in FIG. 10, it is possible to provide a suitable mask for a wearer who requires a long length from the end of the mask main body in the lateral direction D2 to the ear and who desires comfort around the ear.
　図１１に、さらに別の変形例による耳掛け部材２０ａＣ、２０ａＣ（耳掛け部材シート２０Ｃ）を示す。図１１に示す耳掛け部材２０ａＣの基本的な構成は、図６～８を参照して説明した耳掛け部材２０ａと同様であり、耳掛け部材２０ａＣ全体にわたって、縦方向Ｄ１に離間して横方向Ｄ２延在する複数の伸縮性紐材９、９、…が設けられているが、耳掛け部材２０ａＣにおいては、上端部領域Ｅ１及び下端部領域Ｅ２における伸縮性紐材９、９、…の配置間隔（ピッチ）が、中央領域Ｍにおける配置間隔よりも小さくなっている。例えば、中央領域Ｍにおける伸縮性紐材９、９、…の配置間隔ＬＭに対する、上端部領域Ｅ１及び／又は下端部領域Ｅ２における伸縮性紐材９、９、…の配置間隔ＬＥの比の値（ＬＥ／ＬＭ）は、好ましくは１．１～２とすることができる。また、中央領域Ｍにおける伸縮性紐材９、９、…の配置間隔ＬＭは１.１～１０ｍｍ、上端部領域Ｅ１及び／又は下端部領域Ｅ２における伸縮性紐材９、９、…の配置間隔ＬＥは１～５ｍｍであってよい。 FIG. 11 shows ear hooking members 20aC, 20aC (ear hooking member sheet 20C) according to still another modification. The basic configuration of the ear hook member 20aC shown in FIG. 11 is similar to the ear hook member 20a described with reference to FIGS. A plurality of elastic cord members 9, 9, ... extending D2 are provided. In the ear hook member 20aC, the elastic cord members 9, 9, ... The interval (pitch) is smaller than the arrangement interval in the central region M. For example, the ratio of the arrangement interval LE of the elastic cord members 9, 9, . . . The value of (L E /L M ) can preferably be 1.1-2. Further, the arrangement interval L M of the elastic cord members 9, 9, ... in the central region M is 1.1 to 10 mm, and the arrangement of the elastic cord members 9, 9, ... in the upper end region E1 and/or the lower end region E2. The spacing L E may be 1-5 mm.
　端部領域Ｅ１及び下端部領域Ｅ２において伸縮性紐材９、９、…の配置間隔が小さいと、伸縮性紐材９、９、…の数がより密集していることになる。よって、これらの領域、及びこれらの領域にそれぞれ対応する上辺部２３及び下辺部２６を横方向Ｄ２に引張った時に発生する引張応力は、中央領域Ｍで発生する引張応力より大きくなる。上辺部２３及び下辺部２６における引張応力が大きいと、上辺部２３及び下辺部２６がマスク本体１０をより大きな力で引っ張ることができるので、マスク本体を顔の方向により強く抑えることができ、マスク本体を顔により密着させることができる。一方、中央領域Ｍでは、横方向Ｄ２にもある程度の伸縮性があることが好ましいが、伸縮性紐材９、９、…が領域内に密集していない方が耳後方配置部２４を柔軟にでき、装着時の耳周りの違和感を低減できる。よって、図１１に示す例によれば、マスクのフィット性、及び耳周りの快適さを求める装着者に好適な耳掛け部材、及びマスクを提供できる。 When the arrangement intervals of the elastic cord members 9, 9, ... are small in the end region E1 and the lower end region E2, the number of the elastic cord members 9, 9, ... is denser. Therefore, the tensile stress generated when these regions and the upper side portion 23 and the lower side portion 26 corresponding to these regions are pulled in the lateral direction D2 is greater than the tensile stress generated in the central region M. If the tensile stress in the upper side portion 23 and the lower side portion 26 is large, the upper side portion 23 and the lower side portion 26 can pull the mask body 10 with a greater force, so that the mask body can be held down more strongly in the direction of the face. The body can be brought into closer contact with the face. On the other hand, it is preferable that the central region M has a certain degree of elasticity in the lateral direction D2. It is possible to reduce discomfort around the ear when wearing. Therefore, according to the example shown in FIG. 11, it is possible to provide an ear hook member and a mask suitable for a wearer who seeks fit of the mask and comfort around the ears.
　さらに、図１２に、伸縮性紐材の変形例を示す。図１２に示す伸縮性紐材９ｗ、９ｗ、…は、横方向Ｄ２に沿って直線状に延びているのではなく、縦方向Ｄ１に振幅を有する波の形状になっている。図１２（ａ）には、引張力が掛かっていない状態の平面図を示し、図１２（ｂ）には、横方向Ｄ２で両側から引張られた状態の平面図を示す。波状の伸縮性紐材９ｗ、９ｗ、…は、横方向Ｄ２で両側から引張力を受けると、伸縮性紐材９ｗ自体が横方向Ｄ２に伸長するとともに、縦方方向Ｄ１の波形状の振幅が小さくなって、より直線に近付く（図１２（ｂ））。すなわち、波状の伸縮性紐材９ｗ、９ｗ、…が横方向Ｄ２に延在して配置された材料は、横方向Ｄ２に引っ張られた場合に、横方向Ｄ２の長さが長くなるとともに、縦方向Ｄ１の長さが短くなり、その分の材料が横方向Ｄ２の伸長に寄与する。よって、波状の伸縮性紐材９ｗ、９ｗ、…を含む耳掛け部材は、同じ引張力を受けた条件で、直線状の伸縮性紐材９、９、…を含む耳掛け部材（図６等）と比較した場合、横方向Ｄ２により長く伸長できる（伸長性が高い）。言い換えると、波状の伸縮性紐材９ｗ、９ｗ、…を含む耳掛け部材の場合、伸長度合いが同じであっても発生する応力が小さい。そのため、図１２に示す伸縮性紐材９ｗ、９ｗ、…を含む耳掛け部材を用いることで、マスク本体が顔に過度に押し付けられること、また耳掛け部材が耳に押し付けられることを避けたい装着者に好適なマスクを提供できる。 Furthermore, FIG. 12 shows a modified example of the elastic string material. 12 do not extend linearly along the horizontal direction D2, but have a wave shape with amplitude in the vertical direction D1. FIG. 12(a) shows a plan view of a state in which no tensile force is applied, and FIG. 12(b) shows a plan view of a state in which it is pulled from both sides in the lateral direction D2. When the wavy stretchable cord members 9w, 9w, . It becomes smaller and approaches a straight line (Fig. 12(b)). That is, when the material in which the wavy elastic cord members 9w, 9w, . . . The length in direction D1 is shortened, and the corresponding amount of material contributes to the elongation in lateral direction D2. Therefore, the ear hook member including the wavy stretchable cord members 9w, 9w, . . . ), it can be stretched longer in the lateral direction D2 (high stretchability). In other words, in the case of the ear hook member including the wavy stretchable cord members 9w, 9w, . Therefore, by using the ear hook members including the elastic cord members 9w, 9 w, . . . shown in FIG. It is possible to provide a suitable mask for a person.
　以上においては、マスク本体と一対の耳掛け部材とが補助材を介して接合されている形態について説明したが、マスクは、補助材のない構成とすることもできる。図１３に、補助材なしで構成されたマスク１０１を示す。マスク１０１では、一対の耳掛け部材１２０ａ、１２０ａがそれぞれ、マスク本体１０の横方向Ｄ２の端部に、接合部７０、７０で直接接合されている。接合部７０、７０は、マスク１（図１～図５）における外側接合部５０、５０、内側接合部６０、６０と同様の接合手段によって形成できる。また、一対の耳掛け部材１２０ａ、１２０ａは、１枚の耳掛け部材シート１２０を形成している。 In the above description, the mask main body and the pair of ear hook members are joined via the auxiliary material, but the mask can also be configured without the auxiliary material. FIG. 13 shows a mask 101 constructed without auxiliary materials. In the mask 101, a pair of ear hook members 120a, 120a are directly joined to ends of the mask main body 10 in the lateral direction D2 at joining portions 70, 70, respectively. The joints 70, 70 can be formed by the same joint means as the outer joints 50, 50 and the inner joints 60, 60 in the mask 1 (FIGS. 1-5). A pair of ear hook members 120 a and 120 a form one ear hook member sheet 120 .
　なお、図面を参照しながら説明した上記の例及び形態の特徴は、それぞれ単独で構成に含めることができるし、該特徴の２以上を組み合わせて構成に含めることができる。例えば、上端部領域Ｅ１及び下端部領域Ｅ２において伸縮性紐材の太さ及び伸長率を変更した形態の耳掛け部材を構成することもできる。 The features of the above examples and forms described with reference to the drawings can be included in the configuration independently, or two or more of the features can be included in the configuration in combination. For example, it is possible to configure an ear hook member in which the thickness and elongation rate of the elastic cord material are changed in the upper end region E1 and the lower end region E2.
　以下、本発明の具体的な態様を記載する。 Specific embodiments of the present invention are described below.
　（付記１）
　付記１に係る態様は、環状シート状のマスク用耳掛け部材であって、平面視で、マスクの上下方向に対応する第１方向と、前記第１方向に直交する第２方向とを有し、第１表面材と、前記第１表面材と反対側に配置された第２表面材と、前記第１表面材と前記第２表面材との間に、前記第１方向に離間し且つそれぞれ前記第２方向に沿って延在する複数の伸縮性紐材とを備え、前記伸縮性紐材が、伸長状態で前記第１表面材及び前記第２表面材にそれぞれ接着されている。 (Appendix 1)
An aspect according to appendix 1 is an annular sheet-shaped ear hook member for a mask, which has a first direction corresponding to the vertical direction of the mask and a second direction perpendicular to the first direction in plan view. , a first surface, a second surface disposed opposite the first surface, and spaced apart in the first direction between the first surface and the second surface, and respectively and a plurality of stretchable cords extending along the second direction, the stretchable cords being adhered to the first surface member and the second surface member respectively in a stretched state.
　上記付記１に係る態様では、耳掛け部材の伸縮性を、複数の伸縮性紐材を用いることで得ている。そのため、伸縮性紐材（例えば糸ゴム）の材料、太さを適宜選択することで、且つ／又は伸縮性紐材の配置、伸長率等を適宜選択することで、耳掛け部材に任意の伸縮性を付与できる。そのため、使用者の要望に応じた様々なマスク用耳掛け部材を、比較的容易に製造できる。 In the aspect of Supplementary Note 1 above, the stretchability of the ear hook member is obtained by using a plurality of stretchable string members. Therefore, by appropriately selecting the material and thickness of the elastic string (for example, rubber thread) and/or by appropriately selecting the arrangement and elongation rate of the elastic string, the ear hook member can be arbitrarily stretched. can give gender. Therefore, it is possible to relatively easily manufacture various mask ear hook members that meet the needs of users.
　また、伸縮性紐材が、耳掛け部材の全体にわたって設けられており、耳掛け部材の、装着時に装着者の耳の後方に配置される耳後方配置部にも設けられている。これにより、耳掛け部材の、装着時にマスク本体から耳に向かって延びる上辺部及び下辺部のみならず、耳後方配置部もある程度の横方向Ｄ２の伸縮性を有することができるので、快適な装着感を高めることができる。 In addition, the stretchable cord member is provided over the entire ear hook member, and is also provided in the behind-the-ear placement portion of the ear hook member, which is placed behind the wearer's ear when the ear hook member is worn. As a result, not only the upper and lower side portions of the ear hook member extending from the mask main body toward the ear when worn, but also the portion arranged behind the ear can have a certain degree of elasticity in the lateral direction D2, thereby providing comfortable wearing. can heighten your senses.
　（付記２）
　付記２に係る態様では、前記第１表面材及び第２表面材が不織布から構成されている。 (Appendix 2)
In the aspect according to Supplementary Note 2, the first surface material and the second surface material are made of nonwoven fabric.
　上記付記２に係る態様によれば、耳掛け部材における表面材として不織布を用いるので、肌触りのよい耳掛け部材を得ることができる。 According to the aspect according to the second note, a non-woven fabric is used as the surface material of the ear hook member, so it is possible to obtain an ear hook member that feels good on the skin.
　（付記３）
　付記３に係る態様では、前記伸縮性紐材が、前記第１方向に振幅を有する波状に延在している。 (Appendix 3)
In the aspect according to Supplementary Note 3, the elastic cord member extends in a wavy shape having amplitude in the first direction.
　上記付記３に係る態様によれば、波状に配置された伸縮性紐材により、より高い伸長性、すなわち、同じ引張力で比較した場合、自然状態に対する伸長長さをより長くすることができる。 According to the aspect of Appendix 3 above, the stretchable cord material arranged in a wavy pattern has higher stretchability, that is, when compared with the same tensile force, it is possible to increase the stretched length with respect to the natural state.
　（付記４）
　付記４に係る態様では、四角環の形状を有し、前記四角環の上辺及び下辺にそれぞれ相当する上辺部及び下辺部を有し、前記第１方向で見て、前記上辺部の延在範囲に相当する上端部領域と、前記下辺部の延在範囲に相当する下端部領域と、前記上端部領域と前記下端部領域との間の中央領域とを有し、前記複数の伸縮性紐材の太さ、伸長率、及び配置間隔の１以上が、前記上端部領域及び前記下端部領域の少なくとも一方と、前記中央領域とで異なる。 (Appendix 4)
In the aspect according to Supplementary Note 4, it has a quadrangular ring shape, has an upper side portion and a lower side portion respectively corresponding to the upper side and the lower side of the quadrangular ring, and the extension range of the upper side portion when viewed in the first direction , a lower end region corresponding to the extension range of the lower side portion, and a central region between the upper end region and the lower end region, and the plurality of elastic cord materials At least one of the thickness, the elongation rate, and the arrangement interval is different between at least one of the upper end region and the lower end region and the central region.
　上記付記４に係る態様によれば、縦方向で見て、耳掛け部材の領域によって伸縮挙動を異ならせることができる。例えば、上端部領域及び下端部領域に配置された伸縮性紐材の太さをより太く、中央領域に配置された伸縮性紐材の太さをより細くすることで、装着時に耳掛け部材が引っ張られた時に上端部領域及び下端部領域で生じる引張応力を、中央領域で生じる引張応力よりも大きくできる。上端部領域及び下端部領域は、耳掛け部材の、装着時に横方向Ｄ２に大きく引っ張られる上辺部及び下辺部にそれぞれ対応している。上辺部及び下辺部における引張応力が大きいと、マスク本体が耳の方へより強く引っ張られるため、マスク本体を顔により密着させることができる。一方、耳掛け部材の中央領域に対応する耳後方配置部にも、当該部分が耳のカーブに沿って変形できるよう横方向Ｄ２の伸縮性があることが好ましいが、伸縮性部材が太いと装着感を損ねる場合がある。よって、中央領域の伸縮性紐材の太さがより細くなっていることで、耳後方配置部を柔軟に保つことができる。 According to the aspect of Supplementary Note 4, when viewed in the vertical direction, the expansion and contraction behavior can be varied depending on the region of the ear hook member. For example, by increasing the thickness of the elastic cords arranged in the upper end region and the lower end region and by making the thickness of the elastic cords arranged in the central region thinner, the ear hook member can be worn when worn. The tensile stress that occurs in the upper and lower end regions when pulled can be greater than the tensile stress that occurs in the central region. The upper end region and the lower end region respectively correspond to the upper side portion and the lower side portion of the ear hook member that are largely pulled in the lateral direction D2 when worn. When the tensile stress in the upper and lower sides is large, the mask body is pulled more strongly toward the ears, so that the mask body can be brought into closer contact with the face. On the other hand, it is preferable that the behind-the-ear portion corresponding to the central region of the ear hook member also has elasticity in the lateral direction D2 so that the portion can deform along the curve of the ear. It can hurt your feelings. Therefore, since the thickness of the stretchable string material in the central region is thinner, the ear rear portion can be kept flexible.
