しかしながら、従来のものは、ガーゼや不織布などの素材の特性上、透明なマスクを作ることが非常に困難であるため、マスク装着時に装着者の口および鼻がよく見えないという問題がある。特に、従来のように顔面の半分以上が不透明なマスクで覆われた場合、外見上、相対する人に対して大きな違和感を生じさせる。   However, the conventional one has a problem that the mouth and nose of the wearer cannot be seen well when the mask is worn because it is very difficult to make a transparent mask due to the characteristics of materials such as gauze and nonwoven fabric. In particular, when more than half of the face is covered with an opaque mask as in the prior art, a great sense of discomfort is caused to the person facing each other.

そこで本発明では、マスク装着者の口および鼻がよく見え、かつ、従来のマスクと同様の機能を維持し、上述の場面1)〜場面7)などの広い用途で外見上違和感なく使用することができるマスクを提供することを目的とする。   Therefore, in the present invention, the mask wearer's mouth and nose can be seen well, and the same function as that of the conventional mask can be maintained, and used in a wide range of applications such as the above-mentioned scenes 1) to 7) without any uncomfortable appearance. An object of the present invention is to provide a mask that can be used.

本発明は次のような特徴を有し、前記課題を解決する。
・第1に、マスク本体部が透明シート材などの透明または半透明な合成樹脂等による素材で作られるため、装着時に顔の大半が隠れることはない。
・第2に、マスク本体部は、装着時に鼻口部との間に空間が生じる立体形状を有する。
・第3に、マスク本体部は、顎側下部に開口方向が下向きの吹き抜き口を有し、通気性のある通気性素材部が、その吹き抜き口を塞ぐ態様で係合される。
The present invention has the following features and solves the above problems.
First, since the mask body is made of a material such as a transparent sheet material such as a transparent or translucent synthetic resin, most of the face is not hidden when worn.
Second, the mask body has a three-dimensional shape that creates a space between the mask body and the nostril when worn.
Thirdly, the mask main body has a blowout opening whose opening direction is downward in the lower part of the chin side, and a breathable material part having air permeability is engaged in a manner of closing the blowout opening.

すなわち、本発明は、透明または半透明な素材によって形成されるマスク本体部と、前記マスク本体部を顔部に装着させるための係止用部と、通気性を有する素材によって形成される通気性素材部とから構成され、前記マスク本体部は、装着時に鼻口部との間に空間が生じる立体形状であり、該マスク本体部の顎側下部に開口方向が下向きの吹き抜き口を有し、前記通気性素材部は、前記マスク本体部に設けられた吹き抜き口を塞ぐ態様で係合されることを特徴とする。   That is, the present invention relates to a mask main body portion formed of a transparent or translucent material, a locking portion for attaching the mask main body portion to the face, and a breathability formed of a breathable material. The mask main body portion is a three-dimensional shape in which a space is formed between the mask main body portion and the nose mouth portion when worn, and has a blowout opening whose opening direction is downward at the lower jaw side of the mask main body portion. The breathable material portion is engaged in a manner that closes a blowout opening provided in the mask main body portion.

前記マスク本体部の立体形状は、透明または半透明な素材の上部に設けられたV字状切り抜き部の両端部を合わせ、V字状切り抜き部を接合して形成することができる。   The three-dimensional shape of the mask main body can be formed by joining both ends of a V-shaped cutout provided on the top of a transparent or translucent material and joining the V-shaped cutout.

本発明によれば、対面者にとってマスク装着者の顔がよく見え、表情を自然に見せることができるようになり、マスクと装着者の顔部によって生じる空間をよく密閉でき、従来と同様の用途で外見上違和感なく使用可能なマスクを実現できるようになる。   According to the present invention, the face of the mask wearer can be seen well for the face-to-face person, and the expression can be seen naturally, the space created by the mask and the face of the wearer can be well sealed, This makes it possible to realize a mask that can be used without any sense of incongruity.

以下では、図面を参照しながら、本発明の一実施形態を詳細に説明する。   Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

図1は、本実施形態に係る呼吸用透明マスクを斜めから立体的に見た斜視図、図2は、本実施形態に係る呼吸用透明マスクを正面から見た正面図、図3は、本実施形態に係る呼吸用透明マスクの装着時の正面図、図4は、本実施形態に係る呼吸用透明マスクの装着時の横図である。なお、明確化のためマスク装着時の鼻側方向を上部、顎側方向を下部として説明する。   FIG. 1 is a perspective view of the breathing transparent mask according to the present embodiment viewed obliquely and three-dimensionally, FIG. 2 is a front view of the breathing transparent mask according to the present embodiment as viewed from the front, and FIG. FIG. 4 is a front view when the breathing transparent mask according to the embodiment is worn, and FIG. 4 is a horizontal view when the breathing transparent mask according to the embodiment is worn. For clarity, the description will be made with the nose side direction at the time of wearing the mask as the upper part and the chin side direction as the lower part.

図中、1は本実施形態に係るマスク、2は透明(または半透明)なシート材で作られるマスク本体部、2aはマスク本体部2の下部に設けられた吹き抜き口、2bはマスク本体部2の中心線、2cは折れ曲がり部、2dは庇部、2eは襟部、3はマスク本体部2の吹き抜き口2aを覆う通気性素材部、4はマスク本体部2を顔面に装着させるための係止用部、Zは顔の中心線を表している。   In the figure, 1 is a mask according to the present embodiment, 2 is a mask body made of a transparent (or translucent) sheet material, 2a is a blowout port provided at the lower part of the mask body 2, and 2b is a mask body. The center line of the part 2, 2 c is a bent part, 2 d is a collar part, 2 e is a collar part, 3 is a breathable material part covering the blowout opening 2 a of the mask body part 2, and 4 is a mask body part 2 attached to the face For this purpose, Z represents the center line of the face.

マスク本体部2は、ポリエチレン(PET)などの透明な合成樹脂であり、立体的形態を保って顔面にしっかり密着できる程度の硬さと、熱、湿度、酸および塩基、電気分解性などの化学変化に十分な強度を有するものであればよく、体に有害なものでない限り、樹脂原料、製造工程等は特に限定されない。当然のことながら、装着者のそれぞれの使用用途、使用場所および使用目的に従い、採用する合成樹脂は硬度や温度や湿度などに対して異なる性質を有するものを選択できる。   The mask body 2 is a transparent synthetic resin such as polyethylene (PET), and has a hardness that can be firmly attached to the face while maintaining a three-dimensional shape, and chemical changes such as heat, humidity, acid and base, and electrolysis. The resin raw material, the manufacturing process, and the like are not particularly limited as long as they have sufficient strength. As a matter of course, the synthetic resin to be used can be selected from those having different properties with respect to hardness, temperature, humidity, and the like according to each use application, use place, and use purpose of the wearer.

マスク本体部2は、中心線2bに対して対称であり、図4のように、装着時に鼻口部との間に空間が生じる立体形状であり、上部にV字状に折れ曲がり部2cがあり、折れ曲がり部2cで凸状に折れ曲がることにより、上部に庇部2dが形成される。マスク本体部2は、左右横方向に対して「く」の字型もしくは放物状に中心線2bで屈曲し、庇部2dを使用してマスク本体を鼻翼の上を覆う形で押さえて、顔面との固定作用を発揮し、さらに庇部2dを使用して装着時に中心線2bを、図4のように顔の中心面に対して平行もしくは中心線2bの延長と顔の中心線が下部で交わるようにして、マスク本体部2が装着者の顔から大きく飛び出ないようにする。こうして、中心線2bと左右の折れ曲がり部2cの交点からマスク本体部2が顔に向かうようにし、鼻や口などの顔面の凹凸を違和感なくマスク本体部2に収納することができるように形成される。   The mask main body 2 is symmetric with respect to the center line 2b, and has a three-dimensional shape in which a space is formed between the nose and mouth when worn, as shown in FIG. 4, and has a bent portion 2c in a V shape at the top. By bending the bent portion 2c into a convex shape, the flange portion 2d is formed on the upper portion. The mask body 2 is bent at the center line 2b in the shape of a "<" or a parabola in the lateral direction, and holds the mask body over the nose wings using the heel 2d, The centerline 2b is exerted on the face when it is worn using the buttocks 2d, and the centerline 2b is parallel to the center plane of the face as shown in FIG. So that the mask main body 2 does not jump out of the face of the wearer. In this way, the mask main body 2 is directed toward the face from the intersection of the center line 2b and the left and right bent portions 2c, and the mask main body 2 can be accommodated in the mask main body 2 without a sense of incongruity. The

また、マスク本体部2は襟部2eを有し、襟部2eに沿って図3および図4に示されるような顔の鼻屋、頬、顎部に至るまで覆うような立体形状を持ち、また顎部の下側に下向きの吹き抜き口2aを有する。この吹き抜き口2aは、装着時、顔の中心線Zに対して垂直な面上で、略楕円形状、略半楕円形状、または略三角形状の形に形成されている。本発明の目的を損なわない範囲においてマスク本体部2を頬全体に至る範囲までを覆うことも可能である。   Further, the mask body 2 has a collar 2e, and has a three-dimensional shape covering the face nose, cheek, and chin as shown in FIGS. 3 and 4 along the collar 2e. Moreover, it has a downward opening 2a on the lower side of the jaw. The blowout opening 2a is formed in a substantially elliptical shape, a substantially semi-elliptical shape, or a substantially triangular shape on a surface perpendicular to the center line Z of the face when worn. It is also possible to cover the mask main body 2 up to the entire cheek within a range that does not impair the object of the present invention.

通気性素材部3は、マスク本体部2の吹き抜き口2a部分を塞ぐ形で設けられる。この通気性素材部3は、不織布やガーゼなどの通気性のある繊維で作られているが、その原料素材と加工方法、積層条件は特に制限されない。例えば、原料素材では合成繊維、再生繊維、天然繊維もしくはこれら2種類以上で加工された混合繊維などを使用してもよい。また、加工方法として不織布の場合、スパレース不織布、スパンボンド不織布、サーマルボンド不織布、メルトブローン不織布、ニードルパンチ不織布などの公知の製法で製造された不織布を使用してもよい。また積層条件は、光触媒、銀系抗菌剤もしくはこれらの混合物を添着か練り込んだ、SMS不織布、SMMS不織布からなる層を有する積層型不織布を使用してもよい。装着者のそれぞれの使用用途、使用場所および使用目的に従い、様々な繊維を採用できる。   The breathable material portion 3 is provided in a form that closes the blowout opening 2a portion of the mask main body portion 2. The breathable material portion 3 is made of a breathable fiber such as a nonwoven fabric or gauze, but the raw material, processing method, and lamination conditions are not particularly limited. For example, as the raw material, synthetic fiber, regenerated fiber, natural fiber, or mixed fiber processed with two or more of these may be used. Moreover, in the case of a nonwoven fabric as a processing method, you may use the nonwoven fabric manufactured by well-known manufacturing methods, such as a spalace nonwoven fabric, a spun bond nonwoven fabric, a thermal bond nonwoven fabric, a melt blown nonwoven fabric, a needle punch nonwoven fabric. The lamination condition may be a laminated nonwoven fabric having a layer made of an SMS nonwoven fabric or an SMMS nonwoven fabric, which is impregnated or kneaded with a photocatalyst, a silver-based antibacterial agent, or a mixture thereof. Various fibers can be employed according to each use application, use place, and use purpose of the wearer.

通気性素材部3は吹き抜き口2aの周辺縁部で係合され、吹き抜き口2aに嵌まって吹き抜き口2aを覆い、覆い面は下に垂れないように顔の中心線Zに対してほぼ垂直になるように取り付けられる。これにより、装着時の不透明な不織布やガーゼの可視範囲は実面積よりも相当小さくなる。   The breathable material portion 3 is engaged at the peripheral edge of the blowout port 2a, fits into the blowout port 2a and covers the blowout port 2a, and the covering surface does not hang down with respect to the center line Z of the face. So that it is almost vertical. Thereby, the visible range of the opaque nonwoven fabric or the gauze at the time of wearing becomes considerably smaller than the actual area.

係止用部4は、耳掛け用紐の形態、もしくは後頭部に紐を回して装着するような頭掛け用紐の形態、またはマスク本体部2と別体のシート材に細長い形状の切り欠き穴もしくはスリットを設けた形態であり、顔へマスクを密着固定するためにマスク本体部2の上部の適切な位置に接合される。係止用部4がシート材に細長い形状の切り欠け穴もしくはスリットを設けた形態の場合、マスク本体部2と係止用部4とが一体化されて形成されてもよい。   The locking portion 4 is in the form of an ear strap, or a head strap in which the strap is attached to the back of the head, or a notch hole that is elongated in the sheet material separate from the mask body 2. Or it is a form which provided the slit, and in order to fix the mask tightly to the face, it joins to the suitable position of the upper part of mask body part 2. In the case where the locking portion 4 has a form in which a sheet material is provided with an elongated cutout hole or slit, the mask main body portion 2 and the locking portion 4 may be integrally formed.

係止用部4の素材は、従来のマスクに使用されている伸縮性のある不織布や、係止用部4が耳掛け用紐もしくは頭掛け用紐の場合は、糸ゴム等の弾性伸縮部材を挟んだ伸縮性不織布などを使用してもよいが、特に伸縮性や弾性を有し、透き通ったものが好ましい。例えば、弾性伸縮性透明フィルムを素材とし、その表面を肌への刺激の少ないほぼ透き通った吸収性ポリマーで覆ったものなどである。   The material of the locking portion 4 is a stretchable nonwoven fabric used in conventional masks, or an elastic elastic member such as rubber thread when the locking portion 4 is an ear strap or a head strap A stretchable nonwoven fabric or the like sandwiching between layers may be used, but a transparent fabric having stretchability and elasticity is particularly preferable. For example, an elastic stretchable transparent film is used as a raw material, and the surface thereof is covered with a substantially transparent absorbent polymer that is less irritating to the skin.

マスク本体部2、通気性素材部3、係止用部4の部材相互は、ホットメルト接着、ヒートシール接着、超音波溶着、熱圧縮溶着などの公知の接合手段により係合させることができる。また、各部材を一回以上自由に着脱可能なように、例えばメカニカルファスナーを利用してつなぎ止めてもよい。この場合には、各部材の部品の付け替え交換ができ、例えばマスク本体部2を洗って再び使用し、通気性素材部3または係止用部4を使用済みのものから未使用のものにして再使用のマスク本体部2に取り付けることができる。   The members of the mask main body 2, the breathable material portion 3, and the locking portion 4 can be engaged with each other by known joining means such as hot melt adhesion, heat seal adhesion, ultrasonic welding, and thermal compression welding. In addition, each member may be secured using, for example, a mechanical fastener so that it can be freely attached and detached once or more. In this case, the parts of each member can be replaced and replaced. For example, the mask main body 2 is washed and used again, and the breathable material portion 3 or the locking portion 4 is changed from a used one to an unused one. It can be attached to the reusable mask body 2.

上述の本発明の形態により、透明なシート材から形成される立体形状のマスク本体部2で、装着者の口、鼻、頬を覆うため、対面者にマスク装着者の顔がよく見え、かつマスク本体部2は装着時の顎部下部に顔の中心線Zに対して垂直な吹き抜き口2aを有し、その吹き抜き口2aを通気性素材部3が覆うように係合されて構成されるため、通気性素材部3も装着者の顔の中心線Zとほぼ垂直に位置し、通気性素材部3の素材が不透明であっても、通気性素材部3の他者からの可視面積は実面積よりも小さくなる。そのため、外見上違和感なく異物除去フィルターとしてのバリヤ性と呼吸をするための通気性の機能を十分に発揮できるように通気性素材部3の面積を大きくとることができる。   According to the above-described embodiment of the present invention, the mask body 2 having a three-dimensional shape formed of a transparent sheet material covers the wearer's mouth, nose, and cheeks. The mask main body 2 has a blowout opening 2a perpendicular to the center line Z of the face at the lower part of the jaw when worn, and the blowout opening 2a is engaged so that the breathable material part 3 covers it. Therefore, even if the breathable material portion 3 is located substantially perpendicular to the center line Z of the wearer's face and the breathable material portion 3 is opaque, the breathable material portion 3 is visible to others. The area is smaller than the actual area. Therefore, the area of the breathable material portion 3 can be increased so that the barrier function as a foreign matter removal filter and the breathability function for breathing can be sufficiently exhibited without any unnatural appearance.

本発明のマスク装着時に他者からの通気性素材部3の可視面積がどのくらい小さくなるかを、図5を参照しながら説明する。図5は、マスク装着者と他者の真横からの位置関係を模式的に示しており、5aは他者の目、5bは他者からの可視線を表している。   How small the visible area of the breathable material portion 3 from others when the mask of the present invention is worn will be described with reference to FIG. FIG. 5 schematically shows the positional relationship between the mask wearer and the other person from the side, 5a represents the eyes of the other person, and 5b represents the visible line from the other person.

顔の中心線に対して垂直に張られた通気性素材部3の実面積をSとし、通気性素材部3と可視線5bとのなす角度をθとすると、通気性素材部3の他者からの可視範囲はS×sin θとなり、実面積よりも相当小さくなる。例えば、15cmの身長の差がある他者がマスク装着者と50cmの距離でマスク装着を見た場合、通気性素材部3と可視線5bとのなす角度θは約15度であり、可視範囲は実面積の約4分の1となる。他者とマスク装着者との距離が遠ければ遠いほど、可視範囲はかなりの割合で小さくなる。通気性素材部3と可視線5bとのなす角度θは、小さければ小さいほど視覚上望ましいが、30度以下であればほとんど表情を隠すことはない。この角度θは、20度以下であればさらに好ましい。   If the actual area of the breathable material part 3 stretched perpendicularly to the center line of the face is S and the angle between the breathable material part 3 and the visible line 5b is θ, The visible range from is S × sin θ, which is considerably smaller than the actual area. For example, when another person with a height difference of 15 cm looks at the mask wearing at a distance of 50 cm from the mask wearer, the angle θ formed by the breathable material portion 3 and the visible line 5b is about 15 degrees, and the visible range Is about one-fourth of the actual area. The farther the distance between the other person and the mask wearer is, the smaller the visible range becomes. The smaller the angle θ formed between the breathable material portion 3 and the visible line 5b, the better visually, but if it is 30 degrees or less, the expression is hardly hidden. More preferably, the angle θ is 20 degrees or less.

通気性素材部3が覆う吹き抜き口2aの位置は装着時に口の下にあればよく、顎の下であるか否かは特に限定されないが、可視面積よりも相当小さい通気性素材部3の実面積を大きくすること、マスクと顔の作る空間の密閉性を高めることを考慮すれば、顎の下であることが好ましい。また吹き抜き口2aの形状はマスク装着状態時に上から見たとき、図6(A)〜(C)等に示されるように略楕円型形状、略台形型形状、略三角形状のいずれの形状をとってもよく、これ以外の形状をとってもよいが、その形状について重要な点はマスクと顔の作る空間の密閉性を高めることである。なお、図6において、図の右側方向が装着者の顔側となっている。   The position of the blowout opening 2a covered by the breathable material portion 3 only needs to be below the mouth at the time of wearing, and whether or not it is under the chin is not particularly limited, but the breathable material portion 3 considerably smaller than the visible area. In consideration of increasing the actual area and enhancing the sealing of the space formed by the mask and the face, it is preferably under the chin. Further, the shape of the blowout opening 2a is any of a substantially elliptical shape, a substantially trapezoidal shape, and a substantially triangular shape as shown in FIGS. However, an important point about the shape is to enhance the sealing of the space formed by the mask and the face. In FIG. 6, the right side of the figure is the wearer's face side.

さらに、装着時に通気性素材部3の形状は顔の中心線Zと垂直になるようにしてもよいが、通気性素材部3の実面積を大きくとるために、上部に湾曲した形状であってよく、このとき、成形用の芯材を通気性素材部3に取り付けてもよい。また、通気性素材部3はプリーツ加工したものでもよい。   Furthermore, the shape of the breathable material portion 3 may be perpendicular to the center line Z of the face when worn, but in order to increase the actual area of the breathable material portion 3, the shape is curved upward. At this time, a molding core material may be attached to the breathable material portion 3. The breathable material portion 3 may be pleated.

特に、本実施形態における吹き抜き口2aを覆う通気性素材部3は、装着時に鼻や口に直接当たらないため、通気性素材部3に用いる無機抗菌材、抗菌消臭材、香料を、従来のマスクよりも広い許容範囲で使用することができる。   In particular, the breathable material portion 3 that covers the blowout opening 2a in this embodiment does not directly hit the nose or mouth when worn, so that the inorganic antibacterial material, antibacterial deodorant material, and fragrance used in the breathable material portion 3 are conventionally used. It can be used with a wider tolerance than that of the mask.

マスク本体部2が有する襟部2eは顔とマスクが当接する箇所であり、マスク本体部2に対して折り曲げているのが好ましいが、折り曲げていなくてもよい。なお、圧接跡がつき、着用の不快感、つまりかゆみや痛みを伴わないようにするために、襟部2eにほぼ透き通った吸収性ポリマーや薄い不織布や層の薄いガーゼなどを付加して肌への刺激を軽減させるようにすることも好ましい。   The collar 2e of the mask main body 2 is a portion where the face and the mask come into contact with each other, and is preferably bent with respect to the mask main body 2 but may not be bent. In addition, in order to avoid the impression of pressure contact and wearing discomfort, that is, itching and pain, almost transparent absorbent polymer, thin non-woven fabric and thin layer of gauze are added to the collar 2e to the skin. It is also preferable to reduce the irritation.

マスク本体部2の素材は従来の不織布などを使用したマスクよりも硬いことから、マスク本体部2の立体形状を保った状態で、マスクを装着者の顔によく密着させ、マスクと顔の間に生じる空間を長時間よく密閉でき、さらにその空間を広くすることができる。したがって、マスクを装着した状態で口を大きく開いて会話することができ、また、口紅や化粧の付着を防ぐことができる。   Since the material of the mask body 2 is harder than a mask using a conventional nonwoven fabric, the mask body 2 is kept in close contact with the face of the wearer while maintaining the three-dimensional shape of the mask body 2. It is possible to seal the generated space well for a long time and further widen the space. Therefore, it is possible to talk with the mouth wide open while wearing the mask, and it is possible to prevent the attachment of lipstick and makeup.

また、本実施形態のマスクは折り畳み可能であり、例えば図7のように、ある程度フラットに折り畳むことができる。したがって、収納性にも優れている。   Further, the mask of the present embodiment can be folded, and can be folded flat to some extent as shown in FIG. 7, for example. Therefore, the storage property is also excellent.

さらに、マスク本体部2の一部に、吹き抜き口2a以外の切り抜き穴を設け、この切り抜き穴を不織布やガーゼなどで係合して覆うことにより、通気性の機能を高めてもよい。   Furthermore, a breathable function may be enhanced by providing a cutout hole other than the blowout opening 2a in a part of the mask body 2 and covering the cutout hole with a nonwoven fabric or gauze.

また、マスク本体部2の素材が紫外線防止用のシート材であったり、シート材に装着者の口および鼻が見える範囲で色づけをしたり、絵柄が描かれていてもよい。なお、口および鼻が見えない範囲でマスク本体部2を色づけしても、マスク本体部2の立体形状を保った状態でマスクは顔部によく密着し、マスクと顔部に生じる空間を長時間よく密閉でき、その空間を広くすることができるという効果は活かされる。   The material of the mask main body 2 may be a sheet material for preventing ultraviolet rays, the sheet material may be colored in a range where the wearer's mouth and nose can be seen, or a picture may be drawn. Even if the mask main body 2 is colored in a range where the mouth and nose are not visible, the mask adheres well to the face while maintaining the three-dimensional shape of the mask main body 2, and the space generated between the mask and the face is lengthened. The effect of being able to seal well and widen the space is utilized.

通気性素材部3の通気性を有する素材は白色のみに限らず、色づけをしたものを使用してもよく、係止用部4も色づけをしたものを使用してもよい。   The breathable material part 3 is not limited to white but may be colored, or the locking part 4 may be colored.

さらに、装着時の温度環境に大きく影響される装着者の呼吸息によるマスク本体部2の内側のくもりを、例えば、水分の透過性が高く、吸収性を有するセルロースなどを加工した透明な薄膜をマスク本体部2の内側に付加したり、もしくは、マスク本体部2の素材に、水分の透過性が高く、吸収性を有するように加工した素材を用いたりすることにより、かなり抑えることができる。   Further, the cloud inside the mask main body 2 due to the breathing breath of the wearer greatly influenced by the temperature environment at the time of wearing, for example, a transparent thin film processed with cellulose having a high moisture permeability and absorptivity. It can be considerably suppressed by adding it inside the mask body 2 or using a material processed so as to have high moisture permeability and absorbability as the material of the mask body 2.

図8は、マスク本体部2における庇部2dの形成方法の一例を示している。庇部2dは、マスク本体部2の素材である合成樹脂材を加熱による曲げ加工によって形成することもできるが、次のようにして形成することもできる。   FIG. 8 shows an example of a method of forming the flange 2d in the mask main body 2. The flange portion 2d can be formed by bending a synthetic resin material that is a material of the mask main body portion 2 by heating, but can also be formed as follows.

図8(A)に示すように、マスク本体部2のシート材の上部をV字状に切り抜き、V字状切り抜き部6を設ける。このV字状切り抜き部6の両端部を合わせ、図8(B)に示すように、接合部7で接合する。こうすることによって、装着時に鼻の上に庇部2dがくるようにし、マスク本体部2と鼻口部との間に適切な空間が生じるように立体形状を容易に形成することができる。   As shown in FIG. 8A, the upper part of the sheet material of the mask main body 2 is cut out in a V shape, and a V-shaped cutout portion 6 is provided. The both ends of the V-shaped cutout 6 are put together and joined at the joint 7 as shown in FIG. By doing so, it is possible to easily form a three-dimensional shape so that the heel portion 2d is placed on the nose when worn, and an appropriate space is formed between the mask main body portion 2 and the nostril portion.
