Description

本発明は、花粉アレルギーや感染症の予防、飛沫の飛散防止などのために装着される衛生マスクに関する。 The present invention relates to a sanitary mask worn for prevention of pollen allergy and infectious diseases, prevention of splashing, and the like.

花粉アレルギーや感染症の予防などの観点から、マスクを装着する場面が増えている。特に、新型コロナウイルスなどの感染症の世界的な流行により、従来に比べてより長時間にわたって、マスクを装着したままの状態で、日常生活を送る必要性が生じている。 From the viewpoint of preventing pollen allergies and infectious diseases, the number of people wearing masks is increasing. In particular, due to the worldwide epidemic of infectious diseases such as the new coronavirus, it has become necessary to live a daily life while wearing a mask for a longer period of time than in the past.

衛生マスクとしては、幾つかの形態が提案されているが、装着者の耳に掛けて使用するものが広く普及している。このようなマスクの耳掛け紐は、ゴム紐や布片などの伸縮性の素材で構成されている。耳掛け紐の伸縮性による引張力が、衛生マスクにおける布体を、装着者の顔に密着させる力を生じる。 Although several forms of hygiene masks have been proposed, those that are worn on the wearer's ears are widely used. The ear strap of such a mask is made of an elastic material such as a rubber strap or a piece of cloth. The tensile force due to the elasticity of the ear strap creates a force to bring the cloth in the sanitary mask into close contact with the wearer's face.

このような耳掛け紐の引張力は、衛生マスクにおける布体と、装着者の鼻や口元との間に形成される隙間を小さくするために有効ではある。しかしながら、耳かけ紐が装着者の耳と接触する力は、耳掛け紐の引張力が強まることにより増大し、装着者に不快感や痛みを生じさせる問題があった。特に、マスクを長時間装着すると、たとえ耳掛け紐が装着者の耳を圧迫する力が大きくない場合であっても、不快感や痛みが生じやすくなる傾向にあり、問題となっている。 Such a tensile force of the ear strap is effective for reducing the gap formed between the cloth body in the sanitary mask and the wearer's nose and mouth. However, the force with which the ear strap comes into contact with the wearer's ear is increased by increasing the tensile force of the ear strap, which causes a problem of causing discomfort and pain to the wearer. In particular, when the mask is worn for a long time, discomfort and pain tend to occur even when the force of the ear strap to press the wearer's ear is not large, which is a problem.

このようなマスク装着時に生じる耳の不快感や痛みを軽減するアイデアとして、耳掛け紐を太くして接触面積を広げたり、耳掛け紐を柔軟な素材でカバーしたりするものが提案されている（特許文献１等参照）。しかしながら、従来の衛生マスクの耳掛け紐では、耳介の上下の付け根部分のような敏感な部分を圧迫する場合があり、不快感や痛みを十分に解消できない問題がある。 As an idea to reduce the discomfort and pain of the ear caused by wearing such a mask, it has been proposed to thicken the ear strap to increase the contact area or to cover the ear strap with a flexible material. (See Patent Document 1 etc.). However, the ear strap of the conventional hygiene mask may press sensitive parts such as the upper and lower bases of the auricle, and there is a problem that discomfort and pain cannot be sufficiently eliminated.

本発明は、上述した課題を解決するためになされたものであり、長時間装着しても耳が痛くなりにくい耳掛け紐を有する衛生マスクを提供する。 The present invention has been made to solve the above-mentioned problems, and provides a hygienic mask having an ear strap that does not hurt the ears even when worn for a long time.

本発明に係る衛生マスクは、
装着者の口および鼻を覆う布体と、前記布体の両側に取り付けられ前記装着者の耳に掛けられる一対の耳掛け部と、を有する衛生マスクであって、
前記耳掛け部は、曲げ方向の力に対して弾性変形および塑性変形する線材を内蔵する線材部と、少なくとも前記線材部の一方の端部と前記布体の上コーナー部との間を伸縮可能に接続する上側伸縮ひも部と、少なくとも前記線材部の他方の端部と前記布体の下コーナー部との間を伸縮可能に接続する下側伸縮ひも部と、を有し、
前記線材部の長さは、前記上側伸縮ひも部の前記上コーナー部に対する接続位置と、前記下側伸縮ひも部の前記下コーナー部に対する接続位置との間の長さの８０～１５０％である。 The sanitary mask according to the present invention is
A sanitary mask comprising a cloth covering the wearer's mouth and nose, and a pair of ear hooks attached to both sides of the cloth and hung on the wearer's ears.
The ear hook can be expanded and contracted between a wire rod portion containing a wire rod that is elastically deformed and plastically deformed by a force in the bending direction, and at least one end portion of the wire rod portion and the upper corner portion of the cloth body. It has an upper telescopic string portion connected to, and a lower telescopic string portion connecting at least between the other end portion of the wire rod portion and the lower corner portion of the cloth body in a stretchable manner.
The length of the wire rod portion is 80 to 150% of the length between the connection position of the upper telescopic string portion with respect to the upper corner portion and the connection position of the lower telescopic string portion with respect to the lower corner portion. ..

本発明に係る衛生マスクは、耳掛け部に、曲げ方向の力に対して弾性変形および組成変形する線材を内蔵する線材部を有し、その線材部の長さは、上側伸縮ひも部と下側伸縮ひも部の接続位置との間の長さの８０～１５０％である。本願発明に係る衛生マスクでは、曲げ方向の力に対して弾性変形および組成変形する線材が、線材部において芯または骨の役割を果たし、上下伸縮ひも部や下側伸縮ひも部などの引張力とバランスして変形することにより、装着者の耳介の上下端部分と、耳掛け紐との間にすき間を形成する。 The sanitary mask according to the present invention has a wire rod portion containing a wire rod that elastically deforms and compositionally deforms with respect to a force in the bending direction in the ear hook portion, and the length of the wire rod portion is the upper telescopic string portion and the lower portion. It is 80 to 150% of the length between the side expansion and contraction string portion and the connection position. In the sanitary mask according to the present invention, the wire rod elastically deformed and compositionally deformed with respect to the force in the bending direction plays the role of a core or a bone in the wire rod portion, and with the tensile force of the vertical stretchable string portion and the lower stretchable string portion. By being balanced and deformed, a gap is formed between the upper and lower ends of the wearer's auricle and the ear hook string.

耳介の上下端部分は、耳介の中でも比較的柔らかい部分であって敏感であるが、この部分と耳掛け部の間に隙間を形成し、耳掛け部が耳介の敏感な部分に接触することを防止し、長時間装着しても耳が痛くなりにくい耳掛け紐を実現する。なお、線材部は、耳介の上下方向中央付近に対して接触するが、耳介におけるこの部分には軟骨があり、耳介の中でも比較的硬く、耳介の上下端部分ほど敏感ではないと考えられる。このため、本発明に係る衛生マスクは、しっかりと耳に掛けられた状態で長時間装着しても、耳が痛くなりにくい。 The upper and lower ends of the auricle are relatively soft and sensitive in the auricle, but a gap is formed between this part and the auricle, and the auricle contacts the sensitive part of the auricle. It prevents this from happening and realizes an ear hook that does not hurt your ears even when worn for a long time. The wire rod part contacts the vicinity of the center of the auricle in the vertical direction, but this part of the auricle has cartilage, is relatively hard in the auricle, and is not as sensitive as the upper and lower ends of the auricle. Conceivable. Therefore, the sanitary mask according to the present invention is less likely to hurt the ears even when worn for a long time while being firmly hung on the ears.

また、たとえば、前記布体の上辺部には、曲げ方向の力に対して弾性変形および塑性変形する線材を有するノーズフィット部が形成されていてもよく、
前記ノーズフィット部が有する線材と、前記線材部が内蔵する線材とは、同じ材質であってもよい。 Further, for example, a nose fit portion having a wire rod that is elastically deformed and plastically deformed with respect to a force in the bending direction may be formed on the upper side portion of the cloth body.
The wire rod included in the nose-fitting portion and the wire rod contained in the wire rod portion may be made of the same material.

このような衛生マスクは、ノーズフィット部を有することにより、布体の上辺部を、装着者の顔の鼻梁による起伏に沿って塑性変形させることができ、布体と装着者の顔との間の隙間を小さくすることができる。また、耳掛け部における線材部が内蔵する線材と、ノーズフィット部が有する線材とが同じ材質であることにより、布体の上辺と線材部とのしなやかさおよび腰の強さのバランスを好適に保つことができるとともに、材料を調達しやすくしてコストを抑制できる。 By having a nose-fitting portion, such a sanitary mask can plastically deform the upper side portion of the cloth body along the undulations of the wearer's face due to the nasal bridge, and between the cloth body and the wearer's face. The gap between the two can be reduced. Further, since the wire rod built in the wire rod portion in the ear hook portion and the wire rod having the nose fit portion are made of the same material, the balance between the flexibility and the strength of the waist between the upper side of the cloth and the wire rod portion is suitable. It can be kept, and it is easy to procure materials and the cost can be suppressed.

また、たとえば、前記耳掛け部は、前記上側伸縮ひも部と前記下側伸縮ひも部とを繋ぐ中間ひも部をさらに有してもよく
前記上側伸縮ひも部と、前記下側伸縮ひも部と、前記中間ひも部とは、連続するひと繋ぎの伸縮ひも部で構成されていてもよく、
前記線材部は、前記伸縮ひも部を挿通する挿通孔を有してもよい。 Further, for example, the ear hook portion may further have an intermediate string portion connecting the upper telescopic string portion and the lower telescopic string portion, and the upper telescopic string portion, the lower telescopic string portion, and the lower telescopic string portion. The intermediate string portion may be composed of a continuous continuous telescopic string portion.
The wire rod portion may have an insertion hole through which the telescopic string portion is inserted.

このような衛生マスクの耳掛け部は、伸縮ひも部の単位長さ当りの伸縮量を低減することができるため、耐久性が良好である。また、伸縮ひも部を通していることにより、線材部の外径が大きくなり、耳への接触圧を軽減できる。 The ear hook portion of such a sanitary mask has good durability because the amount of expansion and contraction per unit length of the expansion and contraction string portion can be reduced. Further, by passing through the telescopic string portion, the outer diameter of the wire rod portion becomes large, and the contact pressure to the ear can be reduced.

また、たとえば、前記線材部は、前記伸縮ひも部に沿って移動可能であってもよい。 Further, for example, the wire rod portion may be movable along the telescopic string portion.

このような衛生マスクは、耳掛け部における線材部の位置を調整することができるため、耳掛け紐が装着者の耳の敏感な部分に触れないように、線材部の位置を調整することができる。 Since such a sanitary mask can adjust the position of the wire rod in the ear hook, the position of the wire rod can be adjusted so that the ear strap does not touch the sensitive part of the wearer's ear. can.

前記布体は不織布で構成される布本体部を有してもよく、
前記線材部は、前記線材部が内蔵する線材を被覆しており前記布本体部の不織布と同じ材質の不織布で構成される被覆部を有してもよい。 The cloth body may have a cloth body portion made of a non-woven fabric.
The wire rod portion may have a covering portion that covers the wire rod built in the wire rod portion and is made of a non-woven fabric of the same material as the non-woven fabric of the cloth main body portion.

線材部が不織布で構成される被覆部を有することにより、線材部と耳介との接触部分における接触圧を軽減し、マスクの装着感をより向上させることができる。また、布本体部と被覆部とを同じ材質の不織布とすることにより、廃棄物の分別の手間を軽減するとともに、材料を調達しやすくしてコストを抑制できる。 Since the wire rod portion has a covering portion made of a non-woven fabric, the contact pressure at the contact portion between the wire rod portion and the auricle can be reduced, and the wearing feeling of the mask can be further improved. Further, by using a non-woven fabric of the same material for the cloth main body and the covering part, it is possible to reduce the labor of separating waste and to make it easier to procure the material and reduce the cost.

第１実施形態
図１は、本発明の第１実施形態に係る衛生マスク１０を、装着者の顔に面する側とは反対側から見た正面図である。図１に示すように、衛生マスク１０は、装着者の口および鼻を覆う布体２０と、布体２０の両側に取り付けられる一対の耳掛け部３０、３５とを有する。図３に示すように、衛生マスク１０は、耳掛け部３０、３５を、それぞれ装着者の左右の耳に掛けることにより、装着される。 1st Embodiment FIG. 1 is a front view of the hygiene mask 10 according to the first embodiment of the present invention as viewed from the side opposite to the side facing the face of the wearer. As shown in FIG. 1, the hygiene mask 10 has a cloth body 20 that covers the wearer's mouth and nose, and a pair of ear hooks 30 and 35 that are attached to both sides of the cloth body 20. As shown in FIG. 3, the hygiene mask 10 is worn by hanging the ear hooks 30 and 35 on the left and right ears of the wearer, respectively.

衛生マスク１０は、花粉アレルギーや感染症の予防、飛沫の飛散防止などのために、家庭や職場など、さまざまなシチュエーションで使用される。衛生マスク１０としては、家庭用のみには限定されず、病院などで医療用に用いられるものであってもよい。 The hygiene mask 10 is used in various situations such as at home and at work in order to prevent pollen allergies and infectious diseases, and to prevent droplets from scattering. The hygiene mask 10 is not limited to household use, and may be used for medical purposes in hospitals and the like.

図１に示すように、布体２０は、不織布で構成される布本体部２０ａと、布体２０の上辺部２５に形成されるノーズフィット部２６とを有する。布本体部２０ａは、略矩形の外観形状を有する。布体２０の中央部付近には、上辺部２５に平行なプリーツ２８が複数形成されている。図３に示すように、衛生マスク１０を装着した際、プリーツ２８が広がることにより、布体２０が装着者の顔を立体的に覆うことができる。 As shown in FIG. 1, the cloth body 20 has a cloth main body portion 20a made of a non-woven fabric and a nose fit portion 26 formed on the upper side portion 25 of the cloth body 20. The cloth main body portion 20a has a substantially rectangular appearance shape. A plurality of pleats 28 parallel to the upper side portion 25 are formed in the vicinity of the central portion of the cloth body 20. As shown in FIG. 3, when the sanitary mask 10 is worn, the pleats 28 are expanded so that the cloth 20 can three-dimensionally cover the wearer's face.

ただし、衛生マスク１０における布本体部２０ａの材質は、不織布のみには限定されず、ウレタンなどの発泡性樹脂や、綿糸などによるガーゼなど、不織布以外の材質であってもよい。また、布本体部２０ａの形状も、プリーツ２８を有する矩形形状のもののみには限定されず、複数の布片を繋ぎ合わせて立体形状を構成するものであってもよい。 However, the material of the cloth main body 20a in the sanitary mask 10 is not limited to the non-woven fabric, and may be a material other than the non-woven fabric such as a foamable resin such as urethane or gauze made of cotton thread or the like. Further, the shape of the cloth main body portion 20a is not limited to the rectangular shape having the pleats 28, and may be formed by connecting a plurality of cloth pieces to form a three-dimensional shape.

布本体部２０ａのノーズフィット部２６は、曲げ方向の力に対して弾性変形および塑性変形する線材を有する。ノーズフィット部２６が有する線材の材質としては、たとえば、アルミニウムや鉄またはこれらを含む合金のような金属や、形状保持プラスチック（たとえば登録商標「テクノロート」として製品化されているプラスチック材料）などが挙げられる。ノーズフィット部２６は、弾性により布本体部２０ａの上辺部２５に腰の強さを与えるとともに、塑性により人の手の力で形状を変形させることができ、かつ、力が除去された後も変形した形状を保持できるため、布体２０の上辺部２５を、装着者の鼻梁の形状にフィットするように変形させることができる。 The nose-fitting portion 26 of the cloth main body portion 20a has a wire rod that is elastically deformed and plastically deformed with respect to a force in the bending direction. As the material of the wire rod possessed by the nose fit portion 26, for example, a metal such as aluminum, iron or an alloy containing these, a shape-retaining plastic (for example, a plastic material commercialized under the registered trademark “Technoroth”) and the like are used. Can be mentioned. The nose fit portion 26 gives the upper side portion 25 of the cloth main body portion 20a the strength of the waist by elasticity, and can be deformed by the force of a human hand by plasticity, and even after the force is removed. Since the deformed shape can be maintained, the upper side portion 25 of the cloth body 20 can be deformed to fit the shape of the wearer's nasal bridge.

図１に示すように、衛生マスク１０における耳掛け部３０、３５は、布体２０の左右の縦辺に取り付けられている。耳掛け部３０と耳掛け部３５は、衛生マスク１０に略対称に取り付けられている。 As shown in FIG. 1, the ear hooks 30 and 35 in the sanitary mask 10 are attached to the left and right vertical sides of the cloth 20. The ear hook portion 30 and the ear hook portion 35 are attached to the sanitary mask 10 substantially symmetrically.

耳掛け部３０は、線材部３２と、伸縮ひも部３４とを有する。伸縮ひも部３４は、上側伸縮ひも部３４ａと、中間ひも部３４ｃと、下側伸縮ひも部３４ｂとで構成される。上側伸縮ひも部３４ａと、下側伸縮ひも部３４ｂと、中間ひも部３４ｃとは、連続するひと繋ぎのひもとなっている。 The ear hook portion 30 has a wire rod portion 32 and an elastic string portion 34. The telescopic string portion 34 is composed of an upper telescopic string portion 34a, an intermediate string portion 34c, and a lower telescopic string portion 34b. The upper telescopic string portion 34a, the lower telescopic string portion 34b, and the intermediate string portion 34c form a continuous continuous string.

図１に示すように、上側伸縮ひも部３４ａは、少なくとも線材部３２の一方の端部３２ａと布体２０の上コーナー部２１との間を伸縮可能に接続する。また、下側伸縮ひも部３４ｂは、少なくとも線材部３２の他方の端部３２ｂと布体２０の下コーナー部２３との間を伸縮可能に接続する。中間ひも部３４ｃは、線材部３２における挿通孔３２ｃの内部に収容されており、上側伸縮ひも部３４ａと、下側伸縮ひも部３４ｂとを繋いでいる。 As shown in FIG. 1, the upper telescopic string portion 34a is stretchably connected between at least one end portion 32a of the wire rod portion 32 and the upper corner portion 21 of the cloth body 20. Further, the lower telescopic string portion 34b is connected to at least the other end portion 32b of the wire rod portion 32 and the lower corner portion 23 of the cloth body 20 in a stretchable manner. The intermediate string portion 34c is housed inside the insertion hole 32c in the wire rod portion 32, and connects the upper telescopic string portion 34a and the lower telescopic string portion 34b.

図１に示す衛生マスク１０では、伸縮ひも部３４は、上コーナー部２１と下コーナー部２３とに接続するひと繋ぎのゴム紐で構成されているが、耳掛け部３０としては、このような伸縮ひも部３４を有するもののみには限定されない。たとえば、図５に示す衛生マスク１１０のように、上側伸縮ひも部１３４ａが線材部３２の一方の端部１３２ａに固定されており、下側伸縮ひも部１３４ｂが線材部の他方の端部１３２ｂに固定されており、図１に示す中間ひも部３４ｃに相当する構造がない耳掛け部１３０を、耳掛け部３０に代えて用いることも可能である。 In the sanitary mask 10 shown in FIG. 1, the telescopic string portion 34 is composed of a continuous rubber cord connected to the upper corner portion 21 and the lower corner portion 23, but the ear hook portion 30 is as such. It is not limited to those having the telescopic string portion 34. For example, as in the sanitary mask 110 shown in FIG. 5, the upper telescopic string portion 134a is fixed to one end 132a of the wire rod portion 32, and the lower telescopic string portion 134b is attached to the other end portion 132b of the wire rod portion. It is also possible to use the ear hook portion 130 which is fixed and does not have a structure corresponding to the intermediate string portion 34c shown in FIG. 1 in place of the ear hook portion 30.

また、上側伸縮ひも部３４ａおよび下側伸縮ひも部３４ｂを含む伸縮ひも部３４としては、天然ゴム糸やポリウレタン糸などの弾性糸が入った繊維ひもであるゴム紐のほか、ひも状にしたポリウレタンなどの樹脂や、コイル状の弾性ひもなどが挙げられるが、特に限定されない。 Further, the telescopic string portion 34 including the upper telescopic string portion 34a and the lower telescopic string portion 34b includes a rubber string which is a fiber string containing an elastic thread such as a natural rubber thread or a polyurethane thread, and a string-shaped polyurethane. Examples thereof include resins such as, and coiled elastic cords, but the present invention is not particularly limited.

図１に示す耳掛け部３０の線材部３２は、曲げ方向の力に対して弾性変形および塑性変形する線材３２ｅを内蔵する。線材部３２の断面図である図４に示すように、線材部３２は、平板状の線材３２ｅと、線材部３２が内蔵する線材３２ｅを被覆する被覆部３２ｄとを有する。 The wire rod portion 32 of the ear hook portion 30 shown in FIG. 1 contains a wire rod portion 32e that is elastically deformed and plastically deformed with respect to a force in the bending direction. As shown in FIG. 4, which is a cross-sectional view of the wire rod portion 32, the wire rod portion 32 has a flat plate-shaped wire rod 32e and a covering portion 32d that covers the wire rod 32e incorporated in the wire rod portion 32.

線材部３２が内蔵する線材３２ｅの材質は、線材３２ｅを曲げる曲げ方向の力に対して弾性変形および塑性変形するものであれば特に限定されず、たとえば、アルミニウムや鉄またはこれらを含む合金のような金属や、形状保持プラスチック（たとえば登録商標「テクノロート」として製品化されているプラスチック材料）などが挙げられる。 The material of the wire rod 32e incorporated in the wire rod portion 32 is not particularly limited as long as it is elastically deformed and plastically deformed with respect to the force in the bending direction of bending the wire rod 32e, and is, for example, aluminum, iron, or an alloy containing these. Metals and shape-retaining plastics (for example, plastic materials commercialized under the registered trademark "Techno Roth").

線材３２ｅは、耳掛け部３０の連続する方向に沿って設けられている。線材３２ｅは、弾性により線材部３２に腰の強さを与える。そのため、衛生マスク１０の装着時において、線材部３２は、上側伸縮ひも部３８ａおよび下側伸縮ひも部３８ｂなどによる布体２０側への引張力と釣り合って湾曲する（図３参照）。 The wire rod 32e is provided along the continuous direction of the ear hook portion 30. The wire rod 32e gives the wire rod portion 32 the strength of the waist by elasticity. Therefore, when the sanitary mask 10 is attached, the wire rod portion 32 is curved in balance with the tensile force toward the cloth body 20 by the upper telescopic string portion 38a, the lower telescopic string portion 38b, and the like (see FIG. 3).

また、線材部３２は、線材３２ｅの塑性により人の手の力で形状を変形させることができ、かつ、力が除去された後も変形した形状を保持できる。そのため、衛生マスク１０の装着者は、線材部３２をノーズフィット部２６と同様に塑性変形させ、装着時における線材部３２の一方の端部３２ａおよび他方の端部３２ｂの位置を、付け心地が最適となる位置に調整することが可能である。また、衛生マスク１０の装着者は、線材部３２を塑性変形させることにより、耳との引っ掛かりを調整することができる。 Further, the wire rod portion 32 can be deformed by the force of a human hand due to the plasticity of the wire rod 32e, and can maintain the deformed shape even after the force is removed. Therefore, the wearer of the sanitary mask 10 plastically deforms the wire rod portion 32 in the same manner as the nose fit portion 26, and the positions of one end portion 32a and the other end portion 32b of the wire rod portion 32 at the time of wearing are comfortable to wear. It is possible to adjust to the optimum position. Further, the wearer of the sanitary mask 10 can adjust the catching with the ear by plastically deforming the wire rod portion 32.

線材部３２が内蔵する線材３２ｅと、布体２０におけるノーズフィット部２６が有する線材３２ｅとは、同じ材質であることが好ましい。これにより、布体２０の上辺部２５と線材部３２とのしなやかさおよび腰の強さのバランスを好適に保つことができるとともに、材料を調達しやすくして、衛生マスク１０の製造コストを抑制できる。なお、衛生マスク１０の製造工程をより合理化するために、ノーズフィット部２６が有する線材と、線材部３２が内蔵する線材３２ｅは、同材質であるだけでなく、長さおよび太さを含む形状についても、共通とすることができる。 It is preferable that the wire rod 32e incorporated in the wire rod portion 32 and the wire rod 32e included in the nose fit portion 26 of the cloth body 20 are made of the same material. As a result, the balance between the suppleness and the strength of the waist between the upper side portion 25 of the cloth body 20 and the wire rod portion 32 can be appropriately maintained, the material can be easily procured, and the manufacturing cost of the sanitary mask 10 can be suppressed. can. In order to further streamline the manufacturing process of the sanitary mask 10, the wire rod included in the nose fit portion 26 and the wire rod 32e incorporated in the wire rod portion 32 are not only made of the same material but also have a shape including length and thickness. Can also be shared.

図２は、衛生マスク１０を、装着者の顔に面する側から見た背面図である。図２に示すように、線材部３２の長さＬ１は、上側伸縮ひも部３８ａの上コーナー部２１に対する接続位置２１ａと、下側伸縮ひも部３４ｂの下コーナー部２３に対する接続位置２３ａとの間の長さＬ２の８０～１５０％であることが好ましく、１００～１５０％であることがさらに好ましい。 FIG. 2 is a rear view of the hygiene mask 10 as viewed from the side facing the wearer's face. As shown in FIG. 2, the length L1 of the wire rod portion 32 is between the connection position 21a of the upper telescopic string portion 38a with respect to the upper corner portion 21 and the connection position 23a of the lower telescopic string portion 34b with respect to the lower corner portion 23. The length L2 is preferably 80 to 150%, more preferably 100 to 150%.

線材部３２の長さＬ１を、接続位置２１ａ、２３ａ間の長さＬ２に対して所定の比率以上とすることにより、装着者の耳介における繊細な部分に、耳掛け部３０が接触することを好適に防止できる。また、線材部３２の長さＬ１を、接続位置２１ａ、２３ａ間の長さＬ２に対して所定の比率以下とすることにより、耳掛け部３０の着脱時に、耳掛け部３０が頭髪などに引っ掛かりやすくなることを防止したり、衛生マスク１０の装着時に耳掛け部３０が目立ちすぎることを防止したりすることができる。なお、線材部３２の長さＬ１および接続位置２１ａ、２３ａ間の長さＬ２は、布体２０に外力が加えられていない状態を基準とする。 By setting the length L1 of the wire rod portion 32 to a predetermined ratio or more with respect to the length L2 between the connection positions 21a and 23a, the ear hook portion 30 comes into contact with the delicate portion of the auricle of the wearer. Can be suitably prevented. Further, by setting the length L1 of the wire rod portion 32 to a predetermined ratio or less with respect to the length L2 between the connection positions 21a and 23a, the ear hook portion 30 is caught on the hair or the like when the ear hook portion 30 is attached or detached. It is possible to prevent the ear hook portion 30 from becoming too conspicuous when the sanitary mask 10 is worn. The length L1 of the wire rod portion 32 and the length L2 between the connection positions 21a and 23a are based on the state in which no external force is applied to the cloth body 20.

図１および図４に示すように、線材部３２の線材３２ｅは、布本体部２０ａを構成する不織布と同じ材質の不織布で構成される被覆部３２ｄにより被覆されていてもよい。線材部３２が不織布による被覆部３２ｄを有することにより、線材部３２と装着者の耳介との接触部分における接触圧を軽減し、衛生マスク１０の装着感をより向上させることができる。また、装着者の耳付近の肌に触れる可能性の高い線材部３２の表面の材質を、顔に触れる布体２０と共通の不織布とすることにより、線材部３２が肌に接触することによる肌荒れの防止も、図ることができる。 As shown in FIGS. 1 and 4, the wire rod 32e of the wire rod portion 32 may be covered with a covering portion 32d made of a nonwoven fabric of the same material as the nonwoven fabric constituting the cloth main body portion 20a. Since the wire rod portion 32 has the covering portion 32d made of the non-woven fabric, the contact pressure at the contact portion between the wire rod portion 32 and the wearer's auricle can be reduced, and the wearing feeling of the sanitary mask 10 can be further improved. Further, by using a non-woven fabric common to the cloth body 20 that touches the face, the surface material of the wire rod portion 32 that is likely to touch the skin near the wearer's ear is used, so that the wire rod portion 32 comes into contact with the skin and causes rough skin. Can also be prevented.

また、図１、図２および図４に示すように、線材部３２は、伸縮ひも部３４を挿通する挿通孔３２ｃを有しており、線材部３２は、伸縮ひも部３４に沿って移動可能である。このような衛生マスク１０は、耳掛け部３０における線材部３２の位置を調整することができるため、耳掛け部３０が装着者の耳の敏感な部分に触れないように、線材部３２の位置を調整することができる。挿通孔３２ｃを有する線材部３２は、たとえば被覆部３２ｂを構成する不織布を筒状に接着または縫い合わせることにより形成することができるが、線材部３２に製造方法はこれのみには限定されない。 Further, as shown in FIGS. 1, 2 and 4, the wire rod portion 32 has an insertion hole 32c through which the telescopic string portion 34 is inserted, and the wire rod portion 32 can move along the telescopic string portion 34. Is. Since such a sanitary mask 10 can adjust the position of the wire rod portion 32 in the ear hook portion 30, the position of the wire rod portion 32 is prevented so that the ear hook portion 30 does not touch the sensitive portion of the wearer's ear. Can be adjusted. The wire rod portion 32 having the insertion hole 32c can be formed, for example, by adhering or sewing the non-woven fabric constituting the covering portion 32b in a tubular shape, but the manufacturing method for the wire rod portion 32 is not limited to this.

図１および図２に示す耳掛け部３５は、線材部３６と、上側伸縮ひも部３８ａおよび下側伸縮ひも部３８ｂを含む伸縮ひも部３８と、を有する。耳掛け部３５は、上側伸縮ひも部３８ａが布体２０の上コーナー部２２に接続しており、下側伸縮ひも部３８ｂが布体２０の下コーナー部２４に接続しており、布体２０に対する取付位置が、耳掛け部３０に対して対称である。 The ear hook portion 35 shown in FIGS. 1 and 2 has a wire rod portion 36 and a telescopic string portion 38 including an upper telescopic string portion 38a and a lower telescopic string portion 38b. In the ear hook portion 35, the upper telescopic string portion 38a is connected to the upper corner portion 22 of the cloth body 20, and the lower telescopic string portion 38b is connected to the lower corner portion 24 of the cloth body 20. The mounting position with respect to the ear hook portion 30 is symmetrical with respect to the ear hook portion 30.

しかし、耳掛け部３５は、布体２０に対する取付位置が異なることを除き、耳掛け部３０と同様の構成であるため、耳掛け部３５の詳細については、説明を省略する。図３は、衛生マスク１０を装着した装着者を、側方からみた概念図である。図３に示すように、衛生マスク１０は、耳掛け部３０、３５を耳介９２に掛けて装着される。 However, since the ear hook portion 35 has the same configuration as the ear hook portion 30 except that the mounting position with respect to the cloth body 20 is different, the details of the ear hook portion 35 will be omitted. FIG. 3 is a conceptual diagram of a wearer wearing the sanitary mask 10 as viewed from the side. As shown in FIG. 3, the hygiene mask 10 is worn by hanging the ear hooks 30 and 35 on the pinna 92.

図３に示すように、衛生マスク１０では、装着時において、上側伸縮ひも部３８ａおよび下側伸縮ひも部３８ｂなどによる布体２０側への引張力と釣り合って、線材部３２が湾曲する。この際、図３に示すように、線材部３２に内蔵された線材３２ｅ（図４参照）により、線材部３２には腰がある（曲げ方向の力に対して抗する剛性がある）ため、装着者の耳介９２の上下端部分と耳掛け部３５との間には、隙間８２が形成される。 As shown in FIG. 3, in the sanitary mask 10, the wire rod portion 32 is curved in balance with the tensile force toward the cloth body 20 by the upper telescopic string portion 38a, the lower telescopic string portion 38b, and the like when the mask 10 is attached. At this time, as shown in FIG. 3, the wire rod 32e (see FIG. 4) built in the wire rod portion 32 has a waist (the wire rod portion 32 has rigidity to resist the force in the bending direction). A gap 82 is formed between the upper and lower end portions of the wearer's auricle 92 and the ear hook portion 35.

耳介の付け根の上下端部分は、耳介の中でも比較的柔らかい部分であって敏感であり肌荒れも生じやすく、長時間に渡る異物の接触により痛みが生じやすい部分である。衛生マスク１０では、図３に示すように、耳介９２の上下端部分と耳掛け部３５との間に隙間８２を形成し、耳掛け部３５が耳介９２の敏感な部分に接触することを防止することにより、長時間装着しても耳が痛くなりにくい。 The upper and lower ends of the base of the auricle are relatively soft parts of the auricle, which are sensitive and prone to rough skin, and are prone to pain due to contact with foreign substances for a long period of time. In the sanitary mask 10, as shown in FIG. 3, a gap 82 is formed between the upper and lower end portions of the auricle 92 and the auricle portion 35, and the auricle portion 35 comes into contact with the sensitive portion of the auricle 92. By preventing this, your ears will not hurt even if you wear it for a long time.

また、図３に示すように、線材部３２が適度に湾曲することにより、線材部３２が耳介９２の上下方向中央部付近に適切にホールドされて、線材部３２が下方にずれることが防止され、耳介９２と耳掛け部３５との間にできる隙間８２が、衛生マスク１０の装着中、常に維持される。なお、線材部３２は、耳介９２の上下方向中央付近に対して接触するが、耳介９２におけるこの部分には軟骨があり、耳介の中でも比較的硬く、耳介の上下端部分ほど敏感ではないと考えられる。したがって、図３に示す衛生マスク１０は、しっかりと耳に掛けられた状態で長時間装着しても、耳が痛くなりにくい。 Further, as shown in FIG. 3, by appropriately bending the wire rod portion 32, the wire rod portion 32 is appropriately held near the central portion in the vertical direction of the pinna 92, and the wire rod portion 32 is prevented from being displaced downward. The gap 82 formed between the pinna 92 and the ear hook 35 is always maintained while the sanitary mask 10 is worn. The wire rod portion 32 comes into contact with the vicinity of the center of the auricle 92 in the vertical direction, but this part of the auricle 92 has cartilage, is relatively hard in the auricle, and is more sensitive to the upper and lower ends of the auricle. Not considered. Therefore, the hygiene mask 10 shown in FIG. 3 is less likely to hurt the ears even when worn for a long time while being firmly hung on the ears.

第２実施形態
図５は、本発明の第２実施形態に係る衛生マスク１１０を示す正面図である。衛生マスク１１０は、布体２０については図１に示す衛生マスク１０と同様であるが、耳掛け部１３０、１３５の構造が、衛生マスク１０の耳掛け部３０、３５とは異なる。衛生マスク１１０の説明では、衛生マスク１０との相違点のみを説明し、共通点については、衛生マスク１０と同様の符号を付し、説明を省略する。 The second embodiment FIG. 5 is a front view showing the sanitary mask 110 according to the second embodiment of the present invention.
