Description

本発明は、装着者の顔面の鼻や口等を覆うマスクに関するものである。 The present invention relates to a mask that covers a nose, a mouth, and the like of a wearer's face.

前記マスクは、花粉や細菌や塵埃等から鼻や口を保護したり、咳やくしゃみに伴う唾等を捕捉したりするようになっている。このマスクは、ガーゼや不織布等から成るマスク本体と、マスク本体の左右に設けた一対の耳掛けとを有している。 The mask protects the nose and mouth from pollen, bacteria, dust, and the like, and captures saliva and the like associated with coughing and sneezing. This mask has a mask body made of gauze, nonwoven fabric, or the like, and a pair of ear hooks provided on the left and right sides of the mask body.

従来のマスクは、息を吐く際にマスク本体が抵抗となるために、装着者が息苦しさを感じ易いことになる。これに対して、マスク本体に排気弁や排気孔を設けて、鼻や口から息を容易に吐き出すようにしたものは公知である（例えば、特許文献１〜３参照）。 In the conventional mask, since the mask main body becomes a resistance when exhaling, the wearer is likely to feel breathlessness. On the other hand, a mask body provided with an exhaust valve and an exhaust hole so as to easily exhale from the nose or mouth is known (see, for example, Patent Documents 1 to 3).

つまり、特許文献１には、排気弁を設けた防塵マスクが開示されている。特許文献２には、口から吐き出した息を排出する排気弁を設けたマスクが開示されている。特許文献３には、息を排出するための孔を設けたマスクが開示されている。 That is, Patent Document 1 discloses a dust-proof mask provided with an exhaust valve. Patent Document 2 discloses a mask provided with an exhaust valve for discharging breath exhaled from a mouth. Patent Document 3 discloses a mask provided with a hole for discharging breath.

特開２０００−２８８１０４号公報（図１−２）JP 2000-288104 A (FIG. 1-2) 特開２００２−３４５９８５号公報（図２・５）JP 2002-345985 A (FIGS. 2 and 5) 特開２００３−２１０６００号公報（図１）JP 2003-210600 A (FIG. 1)

特許文献１では、排気筒に排気弁が配されており、その分だけ構造が複雑になるうえにマスクが嵩張ることになる。特許文献２でも、排気弁を配する分だけ構造が複雑になる。特許文献３では、排気孔が呼吸口に連通しており、息を吸う際にも外気が呼吸口から吸い込まれてしまい、マスクとしての機能が果たせないおそれがあるところに問題がある。 In Patent Document 1, an exhaust valve is arranged in the exhaust tube, and the structure becomes complicated and the mask is bulky. Even in Patent Document 2, the structure is complicated by the amount of the exhaust valve. In Patent Document 3, the exhaust hole communicates with the breathing port, and there is a problem in that outside air is sucked from the breathing port even when breathing in, and the function as a mask may not be performed.

そこで本発明の目的は、マスクとしての機能を果たしながら鼻や口から息を容易に吐き出すことができ、そのうえで構成が簡単であって安価に製造できるマスクを提供することにある。 Accordingly, an object of the present invention is to provide a mask that can easily exhale from the nose or mouth while fulfilling the function as a mask, and has a simple configuration and can be manufactured at low cost.

本発明に係るマスクの第１１の特徴は、前記第１、第２、第３、第４、第５、第６、第７、第８、第９、第１０の何れかの特徴に加えて、本体基布７を構成する不織布が、極細繊維を含んでいる点にある。 The eleventh feature of the mask according to the present invention is in addition to any of the first, second, third, fourth, fifth, sixth, seventh, eighth, ninth, and tenth features. The nonwoven fabric that constitutes the main body base fabric 7 includes ultrafine fibers.

本発明のマスクは、本体基布７の中央部１２に複数の切り込み１３を入れたので、マスクを装着した状態で鼻や口から息を吐き出したときには、本体基布７の中央部１２の各切り込み１３が開いて（図４の（ａ）参照）、息の一部が各切り込み１３を通ってマスク外へ排出でき、残りの息がマスク本体１を透過してマスク外へ排出できる。
つまり、咳やくしゃみに伴う唾等はマスク本体１でほぼ確実に捕捉されながら、息の一部が各切り込み１３を介してマスク外へ排出されることで、マスク本体１が息の吐き出しの際の抵抗になることが低減される。 In the mask of the present invention, since a plurality of cuts 13 are made in the central portion 12 of the main body base cloth 7, when breathing out from the nose or mouth with the mask attached, each of the central portions 12 of the main body base cloth 7. The cuts 13 are opened (see FIG. 4A), and a part of the breath can be discharged out of the mask through the cuts 13, and the remaining breath can pass through the mask body 1 and be discharged out of the mask.
That is, saliva and the like due to coughing and sneezing are almost certainly captured by the mask body 1, and a part of the breath is discharged out of the mask through each notch 13, so that the mask body 1 discharges the breath. It becomes less to become resistance of.

これにより、装着者３１は、マスクを装着していても呼吸を楽に行うことができる。鼻や口で外気を吸い込んだときには、各切り込み１３がほぼ閉じて（図４の（ｂ）参照）、外気はマスク本体１を透過して鼻や口に吸い込まれる。
つまり、息を吸い込む際には、外気が、マスク本体１で粉塵や花粉や細菌等がほぼ濾過されたのちに、口や鼻から吸い込まれることになる。
その際、本体基布７が不織布に成るので切り込み１３からの繊維の解れ出しがなく、外気が口や鼻から吸い込まれるときは顔面に密着して切り込み１３が開くことがなく、切り込み１３から粉塵や花粉や細菌等が吸い込まれることはなく、マスクの機能が損なわれることはない。 Thus, the wearer 31 can easily breathe even when the mask is worn. When the outside air is sucked in through the nose or mouth, the respective cuts 13 are almost closed (see FIG. 4B), and the outside air passes through the mask body 1 and is sucked into the nose or mouth.
That is, when breathing in, outside air is sucked from the mouth and nose after dust, pollen, bacteria, and the like are almost filtered by the mask body 1.
At that time, since the main body base fabric 7 is a non-woven fabric, there is no unraveling of fibers from the cut 13, and when the outside air is sucked in from the mouth or nose, the cut 13 does not open due to close contact with the face, and the dust from the cut 13. No pollen, bacteria, etc. are inhaled and the function of the mask is not impaired.

本発明では、吐き出された息の一部が各切り込み１３を介して排出されるので、前記息がマスク外へ迅速に排出される。
したがって、吐き出された息に含まれる湿気がマスクに溜まることが低減されて、装着者３１に不快感を与えることが低減される。
また、吐き出された息の一部が各切り込み１３を介して排出される分だけ、息がマスク本体１の縁から吹き出てメガネを曇らすような不都合は回避される。
しかも、マスク本体１に切り込み１３を形成するだけでよいので、弁等の部材を取り付けなくても済み、その分だけマスクの構成が簡単になってコストアップを抑えることができる。
そして、本体基布７が、柔軟可撓で形状が不安定な編物や織物によってではなく、紙と同様に定形のある不織布に成るので裁断や縫製が容易であり、編物や織物に成る在来品に比して効率的にマスクを得ることができる。 In the present invention, since a part of the exhaled breath is discharged through each notch 13, the breath is quickly discharged out of the mask.
Therefore, the moisture contained in the exhaled breath is reduced from being accumulated in the mask, and discomfort to the wearer 31 is reduced.
In addition, inconvenience that the breath blows out from the edge of the mask body 1 and fogs the glasses is avoided by the amount that a part of the exhaled breath is discharged through each notch 13.
In addition, since it is only necessary to form the notch 13 in the mask main body 1, it is not necessary to attach a member such as a valve, and the configuration of the mask can be simplified correspondingly, and the cost increase can be suppressed.
And since the main body base fabric 7 is not a soft, flexible and unstable knitted fabric or woven fabric, but a regular non-woven fabric like paper, it is easy to cut and sew. A mask can be obtained more efficiently than a product.

本発明では、本体基布７を左右に二等分する中心線Ｘ−Ｘに沿って裁断した本体基布７の裁断縁１０が本体基布７の外側に突き出る彎曲した曲線形状を成すので、左側頬当縁３と右側頬当縁５の間を拡布して装着するとき、その裁断縁１０の中央部が外側に向けて隆起し、鼻や口に強く触れ合うことはなく、本体基布７と鼻や口の間に暖気が滞留し、寒気を直接吸い込まれることがなく、鼻や口に強く触れ合って不快感を与えることもなくなる。 In the present invention, since the cutting edge 10 of the main body base cloth 7 cut along the center line XX that bisects the main body base cloth 7 to the left and right forms a curved curve shape that protrudes to the outside of the main body base cloth 7, When the left cheek edge 3 and the right cheek edge 5 are spread and attached, the central portion of the cutting edge 10 is raised outward and does not touch the nose or mouth strongly. The warm air stays between the nose and mouth, and the cold is not directly sucked in, and the nose and mouth are touched strongly and no discomfort is caused.

本発明によると、左側頬当縁３と右側頬当縁５との間の鼻当部１９に切り込み１３を入れたので、口や鼻から吐き出した息が効率よく切り込み１３に当たってマスク外へより迅速に排出することができる。 According to the present invention, since the cut 13 is made in the nose pad 19 between the left cheek edge 3 and the right cheek edge 5, the breath exhaled from the mouth and nose efficiently hits the slit 13 and more quickly out of the mask. Can be discharged.

本発明によると、口の当たる中央部１２の下側部分１５に息が出入りし易い切り込み１３を入れたので、粉塵や花粉や細菌等が外気と共に鼻から直接吸い込まれる虞れは更に軽減する。 According to the present invention, since the notch 13 that allows easy breathing into the lower portion 15 of the central portion 12 where the mouth hits is made, the possibility that dust, pollen, bacteria, and the like are directly sucked from the nose together with the outside air is further reduced.

切り込み１３を曲線形状にすると、切り込み１３の両端間が舌片状に膨出し、息を吐くときは外側に向けて突き出て切り込み１３が開き、息を吸うときは口元等に当って内側に向けて突き出ることはなく切り込み１３が閉じる。
このため、息を吐き出し易く、粉塵や花粉や細菌等が吸い込まれ難くなる。
そして、そのように息を吸うとき、切り込み１３が閉じるとしても、本体基布７が通気性のある不織布で出来ているので、息苦しさを感じさせることはない。 When the notch 13 is curved, both ends of the notch 13 swell in a tongue-like shape. When exhaling, the notch 13 projects outward and the notch 13 opens, and when inhaling, hits the mouth and inward. The notch 13 is closed without protruding.
For this reason, it is easy to exhale, and it becomes difficult for dust, pollen, bacteria, etc. to be inhaled.
And when inhaling in that way, even if the notch 13 is closed, the main body base fabric 7 is made of a breathable nonwoven fabric, so that it does not feel breathless.

本発明のマスクは、本体基布７が複数枚の不織布を重ね合わせた積層構造を成し、各不織布に切り込み１３がそれぞれ設けられているので、積層構造の不織布毎に、繊維密度や繊維の伸び性等を異ならせて、花粉対策用等の使用目的等に応じた種々の仕様のマスクを得ることができる。
そして着用の際には、重なり合う不織布間の切り込み１３と切り込み１３の間に位置ズレが起こり、外気が位置のずれた切り込み１３と切り込み１３の間を迂回して鼻に入り、その迂回経路の数箇所の切り込み１３・１３・１３………に粉塵や花粉や細菌等が捕捉されるので、粉塵や花粉や細菌等が鼻に入り難くなる。 In the mask of the present invention, the main body base fabric 7 has a laminated structure in which a plurality of nonwoven fabrics are overlapped, and the cuts 13 are provided in each nonwoven fabric. It is possible to obtain masks with various specifications according to the purpose of use, such as for pollen countermeasures, by varying the elongation and the like.
When wearing, a positional deviation occurs between the cuts 13 and 13 between the overlapping nonwoven fabrics, and outside air enters the nose by bypassing the positions of the cuts 13 and 13 where the positions are shifted. Since dust, pollen, bacteria, etc. are trapped in the notches 13, 13, 13,..., The dust, pollen, bacteria, etc. are difficult to enter the nose.

左側頬当縁３と右側頬当縁５との向き合う方向に複数条の切り込み１３を断続的に配置するときは、その切り込み１３を細かく（短く）することができ、切り込み１３からの粉塵や花粉や細菌等の入り込みを少なくすることができ、本体基布７も強度的に安定したものとなる。 When the plurality of cuts 13 are intermittently arranged in the direction in which the left cheek edge 3 and the right cheek edge 5 face each other, the cuts 13 can be made fine (short), and dust and pollen from the cut 13 And the entry of bacteria and the like can be reduced, and the main body base fabric 7 is also stable in strength.

本発明のマスクでは、切り込み１３の鼻当縁２側の配置幅Ｗ_u を顎当縁６側の配置幅Ｗ_d よりも狭くしたので、口から吐き出した息が外部に吐き出し易くなる。 In the mask of the present invention, the arrangement width W _u on the nose pad edge 2 side of the notch 13 is narrower than the arrangement width W _d on the chin pad edge 6 side, so that the breath exhaled from the mouth can be easily discharged to the outside.

本発明では、本体基布７と共に耳掛け９・９をも不織布によって構成し、耳掛け９・９の不織布の目付けを本体基布７の不織布の目付けよりも軽くし、耳掛け９・９の不織布の破断時の伸び率を本体基布７の不織布の破断時の伸び率も大きくし、耳掛け９・９の不織布の５％の伸長時の伸長応力を本体基布７の不織布の５％の伸長時の伸長応力よりも小さくし、耳掛け９・９の不織布を本体基布７の不織布よりも伸び易くしたので、装着時に本体基布７が形崩れを起こさず、耳掛け９・９が適度に伸びて耳を強圧することがなく、着用し易いマスクが得られる。 In the present invention, the ear hooks 9 and 9 are made of non-woven fabric together with the main body base fabric 7, and the weight of the non-woven fabric of the ear hooks 9 and 9 is made lighter than the non-woven fabric weight of the main body base cloth 7. The elongation at break of the nonwoven fabric is also increased at the break of the nonwoven fabric of the main fabric 7, and the elongation stress at the elongation of 5% of the nonwoven 9/9 is 5% of the nonwoven fabric of the main fabric 7. Since the non-woven fabric of the ear hooks 9 and 9 is made easier to stretch than the non-woven fabric of the main body base fabric 7, the main base fabric 7 does not lose its shape when worn, and the ear hooks 9 and 9 are not stretched. It is possible to obtain a mask that is easy to wear without stretching the ears to an appropriate level.

本発明では、耳掛け９・９の不織布と本体基布７の不織布に、芯成分が鞘成分のポリマーよりも融点が高い高融点ポリマーに成り、鞘成分が熱融着性低融点ポリマーに成る芯鞘複合合成繊維を使用し、その熱融着性鞘成分によって、耳掛け９・９の不織布や本体基布７の不織布を構成している繊維間を接合したので、形崩れを起こさず、耐久性のあるマスクが得られる。 In the present invention, the non-woven fabric of the ear hooks 9 and 9 and the non-woven fabric of the main body base fabric 7 are high melting point polymers having a melting point higher than that of the sheath component polymer, and the sheath component is a heat-fusible low melting point polymer. Because the core-sheath composite synthetic fiber is used and the fibers constituting the non-woven fabric of the ear hooks 9 and 9 and the non-woven fabric of the main body base fabric 7 are joined by the heat-fusible sheath component, the shape is not deformed. A durable mask is obtained.

本発明では、本体基布７を構成する不織布が極細繊維を含んでいるので、ウィルス等の微細なものであっても確りと捕捉することができる。 In this invention, since the nonwoven fabric which comprises the main body base fabric 7 contains an ultrafine fiber, even if it is fine things, such as a virus, it can capture reliably.

（実施例１）図１ないし図３は、本発明の係るマスクの実施例１を示している。マスク本体１は、図１および図２に示すように、装着者３１の顔面の鼻および鼻の周辺に接する上側の鼻当縁２と、頬に接する左側の頬当縁３および右側の頬当縁５と、顎に接する下側の顎当縁６とで上下左右が縁取られた本体基布７を有しており、その本体基布７の左右の頬当縁３・５に、装着者３１の耳に引っ掛ける左右一対の耳掛け９・９を設けてある。マスクは、粉塵や花粉の捕集、細菌やウィルスの捕集、および咳やくしゃみに伴う唾等の飛来防止のために使用される。 Example 1 FIGS. 1 to 3 show Example 1 of a mask according to the present invention. As shown in FIGS. 1 and 2, the mask body 1 includes an upper nose pad edge 2 in contact with the nose of the face of the wearer 31 and the periphery of the nose, a left cheek pad edge 3 in contact with the cheek, and a right cheek pad. It has a body base cloth 7 whose upper and lower left and right edges are bordered by an edge 5 and a lower jaw contact edge 6 in contact with the chin, and a wearer is attached to the left and right cheek contact edges 3 and 5 of the main body base cloth 7. A pair of left and right ear hooks 9 and 9 are provided to be hooked on 31 ears. The mask is used for collecting dust and pollen, collecting bacteria and viruses, and preventing saliva and the like coming from coughing and sneezing.

マスク本体１は、熱可塑性の合成樹脂繊維からなる不織布を裁断して形成されており、左頬縁側と右頬縁側とに本体基布７を二等分する中心線（Ｘ−Ｘ）に沿って裁断した裁断縁１０が、図２に示すように、本体基布７の前方外側（図２では左側）に突き出る曲線を描いている。前記不織布は、所定の通気性を有している。 The mask body 1 is formed by cutting a nonwoven fabric made of thermoplastic synthetic resin fibers, and is along a center line (XX) that bisects the body base fabric 7 on the left cheek edge side and the right cheek edge side. As shown in FIG. 2, the cut edge 10 cut in this way draws a curve protruding outward from the front side of the main body base fabric 7 (left side in FIG. 2). The nonwoven fabric has a predetermined air permeability.

すなわち、マスク本体１は、左右対称形をなす左半部と右半部とを構成する不織布を二枚重ねにし、前記裁断縁１０で裁断して左半部と右半部とを一体に熱溶着しており、その裁断縁１０が前方外側へ上下間にわたって突出形成されたものとなっている。これによって、装着者３１の顔面に装着した状態で、マスク本体１の前面の左右中央において前方に突曲する立体形状に造形される。マスク本体１の裁断縁１０は、シールすると同時に切断する溶断シールの手法等を用いて形成してもよい。 That is, the mask body 1 is formed by stacking two non-woven fabrics constituting a left half part and a right half part that are symmetric, and is cut by the cutting edge 10 to thermally weld the left half part and the right half part together. The cutting edge 10 is formed so as to protrude forward and outward from the top to the bottom. Thereby, it is shaped into a three-dimensional shape that curves forward at the left and right center of the front surface of the mask body 1 in a state of being worn on the face of the wearer 31. The cutting edge 10 of the mask main body 1 may be formed by using a fusing seal technique for cutting simultaneously with sealing.

不織布には、ポリプロピレン繊維、ポリエチレン繊維、ポリウレタン繊維（スパンデックス）、ポリエチレンテレフタレート繊維、ポリトリメチレンテレフタレート繊維、ポリアミド繊維（ナイロン）、アクリル繊維、セルローズ繊維（レーヨン、コットン、ラミー、ケナフ、パルプ等）等がマスクの使用目的等に応じて選択的に、適宜混合して使用される。中でも、好ましい繊維は、ポリエチレンテレフタレート繊維とポリトリメチレンテレフタレート繊維であり、特に、ストレッチ性に優れたポリトリメチレンテレフタレート繊維を他の繊維と混用することが望ましい。
更に、不織布には、芯成分が鞘成分のポリマーよりも融点が高い高融点ポリマーに成り、鞘成分が熱融着性低融点ポリマーに成る芯鞘複合合成繊維、好ましくはポリエチレンテレフタレート系芯鞘複合合成繊維、更に好ましくは、ポリトリメチレンテレフタレートを鞘成分とするポリトリメチレンテレフタレート系芯鞘複合合成繊維を混用することが望ましい。 Nonwoven fabrics include polypropylene fiber, polyethylene fiber, polyurethane fiber (spandex), polyethylene terephthalate fiber, polytrimethylene terephthalate fiber, polyamide fiber (nylon), acrylic fiber, cellulose fiber (rayon, cotton, ramie, kenaf, pulp, etc.), etc. Are selectively mixed according to the purpose of use of the mask, etc. Among them, preferred fibers are polyethylene terephthalate fiber and polytrimethylene terephthalate fiber, and it is particularly desirable to mix polytrimethylene terephthalate fiber excellent in stretchability with other fibers.
Further, the non-woven fabric has a core-sheath composite synthetic fiber, preferably a polyethylene terephthalate-based core-sheath composite, in which the core component is a high-melting polymer having a higher melting point than the polymer of the sheath component, and the sheath component is a heat-fusible low-melting polymer. It is desirable to use a synthetic fiber, more preferably, a polytrimethylene terephthalate-based core / sheath composite synthetic fiber containing polytrimethylene terephthalate as a sheath component.

各耳掛け９は、本体基布７と一体形成してもよいが、各耳掛け９と本体基布７とを別々に裁断して、例えば、本体基布７の左右の頬当縁３・５に各耳掛け９をそれぞれ熱溶着等で接合してもよい。各耳掛け２における耳を通すための孔１１は、型で抜き加工してもよいし、切れ目を入れておき、切れ目で引き裂くことで形成するようにしてもよい。 Each ear hook 9 may be integrally formed with the main body base cloth 7, but each ear hook 9 and the main body base cloth 7 are cut separately, for example, left and right cheek edges 3 of the main body base cloth 7. Each ear hook 9 may be joined to 5 by thermal welding or the like. The holes 11 for passing the ears in each ear hook 2 may be punched with a mold, or may be formed by making a cut and tearing at the cut.

本体基布７は、図１に示すように、その本体基布７の左側の頬当縁３と右側の頬当縁５との間を、左右の頬当部１６・１７と左右中央部の鼻当部１９とに区分してあり、左右中央部の鼻当部１９には、線分状に切り込んだ複数の切り込み１３を入れてある。各切り込み１３は、裁断縁１０の左右両側にそれぞれ一列づつ上下方向に並べて配してある。各切り込み１３は、左側の頬当縁３と右側の頬当縁５との向き合う左右方向に続く直線状に延びており、図３に示すように本体基布７を前後に貫通している。 As shown in FIG. 1, the main body base cloth 7 is formed between the left cheek edge 3 and the right cheek edge 5 between the left and right cheek portions 16, 17 and the left and right central portions. It is divided into a nose pad portion 19, and a plurality of cuts 13 cut into line segments are made in the right and left nose pad portion 19. The notches 13 are arranged in a line on the left and right sides of the cutting edge 10 in a vertical direction. Each incision 13 extends in a straight line extending in the left-right direction where the left cheek edge 3 and the right cheek edge 5 face each other, and penetrates the main body base fabric 7 forward and backward as shown in FIG.

左右の頬当部１６・１７の左右方向の長さ寸法Ｙ（図１・図２）は、それぞれ４３〜４７ｍｍ（約４５ｍｍ）の範囲内になっており、鼻当部１９の左右方向の長さ寸法Ｚ（図１）は、４３〜４７ｍｍ（約４５ｍｍ）の範囲内になっている。
各切り込み１３の左右方向の長さ寸法Ｓ（図２）は、５〜２５ｍｍの範囲内であることが好ましく、７〜２０ｍｍの範囲内であることがより好ましい。上下の切り込み１３・１３間の間隔寸法Ｐ（図２）は、３〜１２ｍｍの範囲内であることが好ましく、５〜１０ｍｍの範囲内であることがより好ましい。 The length dimension Y (FIGS. 1 and 2) in the left-right direction of the left and right cheek support portions 16 and 17 is in the range of 43 to 47 mm (about 45 mm), respectively. The dimension Z (FIG. 1) is in the range of 43 to 47 mm (about 45 mm).
The length dimension S (FIG. 2) in the left-right direction of each cut 13 is preferably in the range of 5 to 25 mm, and more preferably in the range of 7 to 20 mm. The distance P (FIG. 2) between the upper and lower cuts 13 and 13 is preferably in the range of 3 to 12 mm, and more preferably in the range of 5 to 10 mm.

そのように寸法を設定するのは、切り込み１３の左右方向の長さ寸法Ｓが長くなり過ぎると、呼吸に関係なく切り込み１３が開いたままになる虞れがあり、その長さ寸法Ｓが短か過ぎると、息を吐き出す際に切り込み１３が十分に開かずに呼吸が楽にならない虞れが生じるためである。
又、上下の切り込み１３・１３間の間隔寸法Ｐが長くなり過ぎると、本体基布７に形成できる切り込み１３の本数を少なくせざるを得なくなり、その間隔寸法Ｐが短か過ぎると、マスク本体１の強度が低下して立体形状を保ち難くなるからである。 The dimension is set in such a manner that if the length dimension S in the left-right direction of the notch 13 becomes too long, the notch 13 may remain open regardless of breathing, and the length dimension S is short. This is because when the air is exhaled, the notch 13 is not sufficiently opened when breathing out, and there is a possibility that breathing may not be easy.
If the distance P between the upper and lower cuts 13 and 13 becomes too long, the number of cuts 13 that can be formed in the main body base fabric 7 must be reduced. If the distance P is too short, the mask body This is because the strength of 1 is lowered and it is difficult to maintain a three-dimensional shape.

マスク本体１の本体基布７には、抗菌機能や清涼感機能等を有する機能性液剤等を含浸させてもよく、また本体基布７は、その裏面と表面とで繊維密度や繊維の太さや伸び性等を変えてもよい。
中央部１２には、口に向き合う部分を含んでもよく、あるいは顎や頬に向き合う部分を含んでもよい。 The body base fabric 7 of the mask body 1 may be impregnated with a functional liquid agent having an antibacterial function, a refreshing feeling function, or the like. The sheath elongation may be changed.
The central portion 12 may include a portion facing the mouth, or may include a portion facing the chin or cheek.

実施例１のマスクの作用を説明すると、マスクを装着した状態で鼻や口から息を吐き出したときには、その息によって顔面とマスクとの間の気圧が上昇し、図４の（ａ）に示すように、各切り込み１３が大きく開いて、息の一部が各切り込み１３を通ってマスク外へ排出される。
残りの息は、マスク本体１の本体基布７を透過してマスク外へ排出される。これにより、咳やくしゃみに伴う唾等が本体基布７でほぼ捕捉される一方で、息の一部が各切り込み１３を介してマスク外へ排出される分だけ、マスク本体１が息の吐き出しの際の抵抗になることが低減される。 The operation of the mask of Example 1 will be described. When breathing out from the nose or mouth while wearing the mask, the air pressure between the face and the mask increases due to the breath, as shown in FIG. Thus, each notch 13 opens widely, and a part of the breath passes through each notch 13 and is discharged out of the mask.
The remaining breath passes through the main body cloth 7 of the mask main body 1 and is discharged out of the mask. Thereby, while the saliva etc. accompanying coughing and sneezing are almost captured by the main body base cloth 7, the mask main body 1 exhales as much as a part of the breath is discharged out of the mask through each notch 13. It is reduced to become resistance at the time of.

鼻や口で外気を吸い込んだときには、それに伴って顔面とマスクとの間の気圧が低下して、各切り込み１３の縁がマスクの内側へ吸い込まれ、図４の（ｂ）に示すように、各切り込み１３がほぼ閉じる。
外気は、マスク本体１の本体基布７を透過して粉塵や花粉や細菌等が濾過された後に口や鼻に吸い込まれる。 When the outside air is inhaled by the nose or mouth, the air pressure between the face and the mask is lowered accordingly, and the edge of each incision 13 is inhaled to the inside of the mask, as shown in FIG. Each cut 13 is substantially closed.
The outside air passes through the main body cloth 7 of the mask main body 1 and is sucked into the mouth and nose after dust, pollen, bacteria, and the like are filtered.

（実施例２）図５は、発明に係るマスクの実施例２を示している。
実施例２では、マスク本体１の本体基布７の左右中央部の鼻当部１９における鼻当縁２と顎当縁６との中間に位置する中央部１２より顎当縁６に向かう下側部分１５に複数条の切り込み１３が入れられている。
各切り込み１３は、本体基布７の下側部分１５において、裁断縁１０の左右両側にそれぞれ一列づつ上下方向に並んでいる。 Example 2 FIG. 5 shows Example 2 of the mask according to the invention.
In the second embodiment, the lower side toward the jaw contact edge 6 from the center portion 12 located in the middle of the nose contact edge 2 and the jaw contact edge 6 in the right and left center nose contact portion 19 of the body base cloth 7 of the mask body 1. A plurality of notches 13 are formed in the portion 15.
The cuts 13 are arranged in the vertical direction in a row on the left and right sides of the cutting edge 10 in the lower portion 15 of the main body base fabric 7.

実施例２の各切り込み１３も、左側の頬当縁３と右側の頬当縁５との向き合う左右方向に続く直線状に延びており、マスク本体１を貫通している。
切り込み１３の配置幅Ｗは、切り込み１３の鼻当縁２側の配置幅Ｗ_u から顎当縁６側の配置幅Ｗ_d にかけて漸次広く（長く）なっている。 Each notch 13 of the second embodiment also extends in a straight line extending in the left-right direction where the left cheek contact edge 3 and the right cheek contact edge 5 face each other, and penetrates the mask body 1.
The arrangement width W of the cut 13 gradually becomes wider (longer) from the arrangement width W _u on the nose pad edge 2 side of the cut 13 to the arrangement width W _d on the jaw pad edge 6 side.

鼻当縁２の前端から下側部分１５の上端までの長さ寸法Ｈ（図６）は、８５〜９５ｍｍ（約９０ｍｍ）の範囲内であり、下側部分１５の上端から顎当縁６の前端までの長さ寸法Ｋ（図６）は、５５〜６５ｍｍ（約６０ｍｍ）の範囲内である。尚、鼻当縁２の前端から顎当縁６の前端までの長さ寸法Ｇは、１４５〜１５５ｍｍ（約１５０ｍｍ）の範囲内であり、鼻当縁２の前端から顎当縁６の前端までを繋いだ直線に対するマスク本体１の前縁の最大突出寸法Ｆ（図６）は、２０〜２４ｍｍ（約２２ｍｍ）の範囲内である。 A length dimension H (FIG. 6) from the front end of the nose contact edge 2 to the upper end of the lower portion 15 is in a range of 85 to 95 mm (about 90 mm), and the upper end of the lower portion 15 to the jaw contact edge 6. The length dimension K (FIG. 6) to the front end is in the range of 55 to 65 mm (about 60 mm). In addition, the length dimension G from the front end of the nose contact edge 2 to the front end of the jaw contact edge 6 is in the range of 145 to 155 mm (about 150 mm), and from the front end of the nose contact edge 2 to the front end of the jaw contact edge 6. The maximum protruding dimension F (FIG. 6) of the front edge of the mask body 1 with respect to the straight line connecting the two is in the range of 20 to 24 mm (about 22 mm).

切り込み１３の鼻当縁２側の配置幅Ｗ_u は、５〜１２ｍｍの範囲内にするとよく、好ましくは、７〜１０ｍｍの範囲内にする。
切り込み１３の顎当縁６側の配置幅Ｗ_d は、１５〜２５ｍｍの範囲内にするとよく、好ましくは、１５〜２０ｍｍの範囲内にする。
切り込み１３の鼻当縁２側の配置幅Ｗ_u と顎当縁６側の配置幅Ｗ_d との比（Ｗ_u ／Ｗ_d ）は、０．４〜０．６の範囲内にするとよく、好ましくは０．５にするとよい。 The arrangement width W _u on the nose pad edge 2 side of the cut 13 may be in the range of 5 to 12 mm, and preferably in the range of 7 to 10 mm.
The arrangement width W _d on the jaw abutment edge 6 side of the cut 13 is preferably in the range of 15 to 25 mm, and preferably in the range of 15 to 20 mm.
The ratio (W _u / W _d ) between the arrangement width W _u on the nose pad edge 2 side of the cut 13 and the arrangement width W _d on the chin pad edge 6 side is preferably within a range of 0.4 to 0.6, Preferably it is 0.5.

各切り込み１３の左右方向の長さ寸法Ｓや、上下の切り込み１３・１３間の間隔寸法Ｐは、実施例１と同様の範囲内に設定するとよい。
その他の点は、実施例１と同じであるので説明を省略する。
切り込み１３の配置幅Ｗは、切り込み１３の鼻当縁２側の配置幅Ｗ_u よりも顎当縁６側の配置幅Ｗ_d の方が階段状に広くなるように設定してもよい。 The length dimension S in the left-right direction of each notch 13 and the distance dimension P between the upper and lower notches 13 and 13 are preferably set within the same ranges as in the first embodiment.
Since the other points are the same as those of the first embodiment, description thereof is omitted.
The arrangement width W of the cut 13 may be set so that the arrangement width W _d on the jaw contact edge 6 side is wider than the arrangement width W _u on the nose contact edge 2 side of the cut 13.

各切り込み１３は、図６に示すように、裁断縁１０でのシール部分を含むように切り込んで形成してもよい。
この場合も、切り込み１３の配置幅Ｗは、切り込み１３の鼻当縁２側の配置幅Ｗ_u よりも顎当縁６側の配置幅Ｗ_d の方が階段状に広くなるように設定してもよい。
各切り込み１３の左右方向の長さ寸法Ｓや、上下の切り込み１３・１３間の間隔寸法Ｐは、実施例１と同様に設定することが好ましい。 As shown in FIG. 6, each cut 13 may be formed by cutting so as to include a seal portion at the cutting edge 10.
Also in this case, the arrangement width W of the cut 13 is set so that the arrangement width W _d on the chin abutment edge 6 side is wider than the arrangement width W _u on the nose pad edge 2 side of the cut 13. Also good.
The length dimension S in the left-right direction of each notch 13 and the distance dimension P between the upper and lower notches 13 and 13 are preferably set in the same manner as in the first embodiment.

切り込み１３の形状としては、任意の形状に設定することができ、例えば図７に示すように、＋字形状（図７の（ａ））、三叉形状（図７の（ｂ））、横向きのＶ字形状（図７の（ｃ））、横向きのＵ字形状（図７の（ｄ））、横向きのＳ字形状（図７の（ｅ））、Ｗ字形状（図７の（ｆ））あるいは格子状（図７の（ｇ））等であってもよく、これらを横方向や縦方向に並べたものであってもよい。 The shape of the notch 13 can be set to an arbitrary shape. For example, as shown in FIG. 7, a + character shape (FIG. 7A), a trident shape (FIG. 7B), a lateral orientation V-shape (FIG. 7C), horizontal U-shape (FIG. 7D), horizontal S-shape (FIG. 7E), W-shape (FIG. 7F) ) Or a lattice shape ((g) in FIG. 7) or the like may be arranged in the horizontal direction or the vertical direction.

マスク本体１の本体基布７は、図８の（ａ）に示すように、通気性を有する２枚の不織布２０・２１を、前後に重ね合わせた２層の積層構造であってもよく、図９の（ａ）に示すように、通気性を有する３枚の不織布２２・２３・２４を、前後に３層に重ね合わせた積層構造であってもよい。
この場合、各不織布２０〜２４には、実施例１や実施例２と同様に、複数条の切り込み１３を設ける。
この例によれば、図８の（ｂ）や図９の（ｂ）に示すように、着用の際に重なり合う不織布間の切り込み１３と切り込み１３の間に位置ズレが起こり、外気が位置のずれた切り込み１３と切り込み１３の間を迂回して鼻に入り、その迂回経路の数箇所の切り込み１３・１３・１３………に粉塵や花粉や細菌等が捕捉される。従って、粉塵や花粉や細菌等が鼻に入り難くなる。 As shown in FIG. 8 (a), the main body fabric 7 of the mask main body 1 may have a two-layer laminated structure in which two nonwoven fabrics 20 and 21 having air permeability are overlapped on the front and back. As shown to (a) of FIG. 9, the laminated structure which piled up the nonwoven fabric 22 * 23 * 24 of 3 sheets which has air permeability on the back and front may be sufficient.
In this case, each of the nonwoven fabrics 20 to 24 is provided with a plurality of cuts 13 as in the first and second embodiments.
According to this example, as shown in FIG. 8 (b) and FIG. 9 (b), misalignment occurs between the notch 13 and the notch 13 between the nonwoven fabrics that overlap each other when worn, and the outside air is displaced. A detour between the cuts 13 and 13 enters the nose, and dust, pollen, bacteria, and the like are captured at several cuts 13, 13, 13... In the detour path. Accordingly, it is difficult for dust, pollen, bacteria, etc. to enter the nose.

また、マスク本体１の本体基布７は、図１０に示すように、通気性を有する不織布製の４枚の不織布２６・２７・２８・２９を、前後（図１０では上下方向）に４層に重ね合わせた積層構造であってもよく、５枚以上の不織布を前後に重ね合わせた積層構造であってもよい。
この場合も、実施例１や実施例２と同様に、各不織布に複数条の切り込み１３が設けられ、着用の際に重なり合う不織布間の切り込み１３と切り込み１３の間に位置ズレが起こることになる。 Further, as shown in FIG. 10, the main body base fabric 7 of the mask main body 1 has four layers of nonwoven fabrics 26, 27, 28, and 29 made of nonwoven fabric having air permeability in the front-rear direction (vertical direction in FIG. 10). It may be a laminated structure superposed on each other, or may be a laminated structure obtained by superposing five or more nonwoven fabrics on the front and back.
Also in this case, similarly to Example 1 and Example 2, each nonwoven fabric is provided with a plurality of cuts 13, and misalignment occurs between the cuts 13 and the cuts 13 between the overlapping nonwoven fabrics when worn. .

マスク本体１の本体基布７を複数枚の不織布で積層構造にする場合、各層の不織布の材質や厚さや繊維密度や繊維の伸び性等を変えることができる。
つまり、各層で伸縮率、吸水率、吸水膨張率あるいは加湿性能を変えて、使用目的等に的確に合ったマスクを形成することができる。 When the main body fabric 7 of the mask main body 1 is formed into a laminated structure with a plurality of nonwoven fabrics, the material, thickness, fiber density, fiber elongation, etc. of the nonwoven fabric of each layer can be changed.
That is, it is possible to change the expansion / contraction rate, the water absorption rate, the water absorption expansion rate, or the humidification performance in each layer to form a mask that exactly matches the purpose of use.

積層構造の本体基布７では、マスクを装着者３１の顔面に装着したときに本体基布７が湾曲し、その本体基布７の湾曲によって、図８の（ｂ）や図９の（ｂ）に示すように各不織布の切り込み同士１３・１３がズレ易くなり、それによって、鼻や口で外気を吸い込んだときには、各不織布の切り込み１３が隣りの不織布で塞がれて、外気が切り込み１３のみを通って鼻や口に吸い込まれることが防止される。
つまり、外気は、マスク本体１の本体本体基布７を確実に透過して濾過される。 In the main body cloth 7 having a laminated structure, the main body cloth 7 is curved when the mask is attached to the face of the wearer 31, and the bending of the main body cloth 7 causes the bending of the main body cloth 7 of FIG. ), The cuts 13 and 13 of each nonwoven fabric are easily misaligned, so that when the outside air is inhaled by the nose or mouth, the cuts 13 of each nonwoven fabric are blocked by the adjacent nonwoven fabric and the outside air is cut 13. It is prevented from being sucked into the nose and mouth only through.
That is, the outside air is surely permeated through the main body base fabric 7 of the mask main body 1 and filtered.

（実施例３）図１１は、発明に係るマスクの実施例３を示しており、実施例３では、各切り込み１３が、左側の頬当縁３と右側の頬当縁５との向き合う方向に続く曲線を描いており、その各切り込み１３の曲線の長さ寸法Ｍが、切り込み１３の両端間の距離Ｌよりも長くなるよう設定してある。
実施例３では、複数条の各切り込み１３が、左側頬当縁３と右側頬当縁５が向き合う方向に断続的に配置されている。 (Example 3) FIG. 11 shows Example 3 of the mask according to the invention. In Example 3, each notch 13 is in a direction in which the left cheek edge 3 and the right cheek edge 5 face each other. The following curve is drawn, and the length dimension M of each cut 13 is set to be longer than the distance L between both ends of the cut 13.
In the third embodiment, the plurality of notches 13 are intermittently arranged in a direction in which the left cheek edge 3 and the right cheek edge 5 face each other.

また、マスク本体１の本体基布７の内側には、補助フィルタ３０が配される。
補助フィルタ３０には、遠赤外線放射作用等を有する粉末等の付着による保温やマイナスイオン発生機能、銀イオンの付着による抗菌機能、活性炭や消臭剤等の付着による消臭機能、植物エキスや各種効能を有する薬剤の配合や付着による薬効機能、清涼剤の配合等による清涼感機能、ミネラル水や還元電位水や電子磁場水等による濾過作用の向上機能等の機能性を付与することができる。
その他の点は、実施例１と同じであるので説明を省略する。 In addition, an auxiliary filter 30 is disposed inside the main body base fabric 7 of the mask main body 1.
Auxiliary filter 30 has heat retention and negative ion generation function by adhesion of powder having far infrared radiation action, antibacterial function by adhesion of silver ion, deodorization function by adhesion of activated carbon and deodorant, plant extract and various kinds Functionality such as a medicinal effect function by blending or adhering a drug having efficacy, a refreshing feeling function by blending with a refreshing agent, a function of improving filtration by mineral water, reducing potential water, electronic magnetic field water, or the like can be imparted.
Since the other points are the same as those of the first embodiment, description thereof is omitted.

実施例３において、各切り込み１３の曲線の長さ寸法Ｍは１０〜１５ｍｍの範囲内に設定され、直線距離Ｌは５〜１０ｍｍの範囲内に設定される。
その長さ寸法Ｍと直線距離Ｌが長過ぎると、呼吸に関係なく切り込み１３が開いたままになる虞がある。
それとは逆に、その長さ寸法Ｍと直線距離Ｌが短か過ぎると、息を吐き出す際に切り込み１３が十分に開かず、息苦しくなる虞がある。 In Example 3, the length dimension M of the curve of each incision 13 is set within a range of 10 to 15 mm, and the linear distance L is set within a range of 5 to 10 mm.
If the length dimension M and the linear distance L are too long, the cut 13 may remain open regardless of breathing.
On the contrary, if the length dimension M and the linear distance L are too short, the notch 13 does not open sufficiently when exhaling, and there is a possibility that the patient may become stuffy.

実施例３の各切り込み１３は、直径１ｃｍの円で示す単位面積３．１４ｃｍ² の中に１〜５個程度含まれるようにマスク本体１の前面の上下左右に並べられる。
実施例３においても、左側の頬当縁３と右側の頬当縁５との向き合う方向に続く切り込み１３の配置幅Ｗは、切り込み１３の鼻当縁２側の配置幅Ｗ_u から顎当縁６側の配置幅Ｗ_d にかけて漸次広くなるように設定してもよい。 The cuts 13 of the third embodiment are arranged vertically and horizontally on the front surface of the mask body 1 so that about 1 to 5 are included in a unit area of 3.14 cm ² indicated by a circle having a diameter of 1 cm.
Also in the third embodiment, the arrangement width W of the cut 13 following the facing direction of the left cheek edge 3 and the right cheek edge 5 is determined from the arrangement width W _u of the cut 13 on the nose pad edge 2 side. it may be set to become gradually wider toward 6 side of the arrangement width W _d.

マスク本体１の本体基布７は、装着者３１の顔面に装着したときには、顔面の凹凸に応じて、図１２の（ａ）から図１２の（ｂ）や（ｃ）や（ｄ）に示すように湾曲し、それに合わせて各切り込み１３が開き易くなるので、息の吐き出しの際に受ける抵抗感が確実に軽減される。 When the body base fabric 7 of the mask body 1 is worn on the face of the wearer 31, it is shown in FIGS. 12 (a) to 12 (b), 12 (c) and 12 (d) according to the unevenness of the face. Since each notch 13 is easily opened in accordance with the curve, the feeling of resistance received when exhaling is surely reduced.

なお、実施例１の各切り込み１３では、マスク本体１が、図１２の（ｃ）に示すように左右方向に湾曲したときには、各切り込み１３が開き難く、図１２の（ｂ）や（ｄ）に示すように上下方向に湾曲したときには、各切り込み１３が開き易くなる。
各切り込み１３の方向や形状は、これらの点を考慮して設定される。 In addition, in each notch 13 of Example 1, when the mask main body 1 curves in the left-right direction as shown in FIG. 12C, each notch 13 is difficult to open, and FIG. 12B and FIG. As shown in FIG. 5, when the curve is made in the vertical direction, each notch 13 is easily opened.
The direction and shape of each cut 13 are set in consideration of these points.

マスク本体１の本体基布７を、前記不織布の積層構造にする場合には、各層の不織布をエンボスローラ等を用いて各層どうしを部分的あるいは不織布全体を溶着させてもよい。
切り込み１３は、アールカッター（回転ロールカッター）を用いた工程等で形成してもよい。 When the main body base fabric 7 of the mask main body 1 has a laminated structure of the nonwoven fabric, the nonwoven fabric of each layer may be welded partially or entirely with each other using an embossing roller or the like.
The cut 13 may be formed by a process using a round cutter (rotary roll cutter).

補助フィルタ３０は、装着者３１の顔面にマスク本体１と共に装着した場合に、前面の左右中央において前方に円弧状に突曲する立体形状に成形してもよい。 When the auxiliary filter 30 is mounted on the face of the wearer 31 together with the mask body 1, the auxiliary filter 30 may be formed into a three-dimensional shape that curves forward in an arc shape at the left and right center of the front surface.

本体基布７には、目付け３０〜１５０ｇ／ｃｍ² の不織布、好ましくは目付５０〜１２０ｇ／ｃｍ² の不織布を用いるとよい。
耳掛け９には、目付け２０〜５０ｇ／ｃｍ² の不織布、好ましくは４０ｇ／ｃｍ² 前後（４０±５ｇ／ｃｍ² ）の不織布、特に、長繊維に成る不織布を用いることが望ましい。
本体基布７に用いる不織布は、短繊維に成るものであってもよい。 The body base cloth 7, basis weight 30 to 150 g / cm ² of nonwoven, preferably in an basis weight 50 to 120 / cm ² nonwoven fabric.

The nonwoven fabric used for the main body base fabric 7 may be a short fiber.

切り込み１３は、例えば図１３に示すように、平面状のマスク本体１の本体基布７に設けてもよい。
平面状のマスク本体１の場合、各切り込み１３は、鼻孔に向き合う本体基布７の左右方向の中央部１２に設けることになる。
耳掛け９には、ゴム紐を使用することもできる。
補助フィルタ３０には、紙を含む種々の不織布を使用することができる。 For example, as shown in FIG. 13, the notch 13 may be provided in the main body base fabric 7 of the planar mask main body 1.
