Description

本発明は、密着性及び装着感を向上させた医療用、防塵用、花粉症対策などに有効なマスクに関するものである。
The present invention relates to a mask effective for medical use, dustproof use, hay fever countermeasures, etc. with improved adhesion and wearing feeling.

マスクは、顔面の密着性を高め微小粒子の吸い込みを防止する観点から重要である。マスクの形状は、大きく分けるとプリーツ型のものと立体型のものとがあり、蛇腹に畳んであるものを広げて使うプリーツ型と、顔の形状に沿ったデザインの形成タイプの立体型があるが、マスクを効果的に使用するには、マスクを顔面に密着させ、尚且つ息苦しくなく、長時間使用できることが重要である。
従来から種々のタイプのマスクが提案されている。例えば特許文献１には、マスク着用前の覆い部が、鼻部分に当たる中央部から縦方向に折り曲げられ、着用時にマスクを上下方向に引っ張ることで、マスクの鼻部分が、三角形の立体形状になり、これによって顔面の鼻部分の隙間を解消し、密着性を高めるマスクが記載されている。
また、特許文献２には、マスクと鼻部分の隙間を塞ぎ、顔面に密着させて使用するマスクが記載されている。
さらに、特許文献３、４、５には、プリーツ型マスクと顔面との隙間を塞ぎ、密着性を高めたマスクが記載されている。
さらに、特許文献６、７にあるように、立体形状タイプのマスクは、顔の形状に沿った覆い部を形成することで、口や鼻の周りに空間を確保し、併せて鼻や頬の隙間を無くすことで、密閉性を高めている。 The mask is important from the viewpoint of enhancing the adhesion of the face and preventing the inhalation of fine particles. The shape of the mask can be broadly divided into pleat type and three-dimensional type. There is a pleat type that uses a foldable bellows, and a three-dimensional type that forms the design according to the shape of the face. However, in order to use the mask effectively, it is important that the mask is in close contact with the face and is not stuffy and can be used for a long time.
Conventionally, various types of masks have been proposed. For example, in Patent Document 1, the cover part before wearing the mask is bent in the vertical direction from the center part that hits the nose part, and the nose part of the mask becomes a triangular three-dimensional shape by pulling the mask up and down during wearing. Thus, a mask is described that eliminates the gap in the nose of the face and improves the adhesion.
Patent Document 2 describes a mask that is used by closing a gap between a mask and a nose portion and in close contact with the face.
Further, Patent Documents 3, 4, and 5 describe a mask that closes a gap between a pleated mask and a face to improve adhesion.
Furthermore, as disclosed in Patent Documents 6 and 7, the three-dimensional shape mask secures a space around the mouth and nose by forming a cover portion along the shape of the face. Sealing is improved by eliminating the gap.

しかしながら、特許文献１、２、３、４、５の形態では、マスク装着時に覆い部を上下方向に引き伸ばす力が、マスクの左右両端部に掛かり、頬に面した覆い部が前方に引かれ、頬部で大きく湾曲して頬部に隙間が生じる。また、鼻の形状は、装着者により多種多様であるため、装着者の鼻の形状に合わすのは困難であり、しかも、鼻の両脇に隙間が生じてマスクとしての効果を十分発揮させることができない。 However, in the forms of Patent Documents 1, 2, 3, 4, and 5, when the mask is worn, the force that stretches the cover in the vertical direction is applied to the left and right ends of the mask, and the cover facing the cheek is pulled forward, A large curve is formed at the cheek and a gap is formed at the cheek. In addition, since the shape of the nose varies depending on the wearer, it is difficult to match the shape of the wearer's nose. I can't.

また、特許文献６，７の形態では、覆い部は、前方に立体形成し、マスクを効果的に装着者の顔面に密着させて口や鼻の空間を確保することができる。しかし、微小粒子の吸い込み防止性能が高いマスクは、隙間を塞ぎ、密閉性が高く設定されているので、マスク装着時に呼吸が苦しくなり、長時間の使用ができない課題がある。
さらに、安価で購入できるマスクの構造では、マスク装着時のマスク内の呼吸気圧を調整することは難しく、マスクのシート面を介して通気できない呼気や吸気がマスクの隙間から吸排し、マスクの密閉性が保てない課題がある。
本発明は、マスクと着用者の鼻の両脇や頬と顎との隙間を解消し、密着性と装着感を高め、プリーツ型マスクと立体型マスクとの双方の利点と欠点を重視することで、マスクの効果をより発揮するマスクの提供を目的とする。 Further, in the forms of Patent Documents 6 and 7, the cover part can be three-dimensionally formed forward, and the mask and the face of the wearer can be effectively brought into close contact with each other to ensure the mouth and nose spaces. However, since a mask with high performance for preventing the inhalation of fine particles closes the gap and has high sealing properties, breathing becomes difficult when the mask is worn, and there is a problem that it cannot be used for a long time.
Furthermore, with a mask structure that can be purchased at low cost, it is difficult to adjust the respiration pressure in the mask when the mask is worn, and exhaled air or inhalation that cannot be vented through the mask seat surface is sucked and exhausted from the gap of the mask, and the mask is sealed. There is a problem that cannot be maintained.
The present invention eliminates the gap between the mask and both sides of the wearer's nose and cheeks and chin, enhances the adhesion and wearing feeling, and emphasizes the advantages and disadvantages of both the pleated mask and the three-dimensional mask. Therefore, an object of the present invention is to provide a mask that exhibits the effect of the mask.

本発明の請求項１に係るマスクは、少なくとも鼻と口を覆う覆い部と、前記覆い部を耳に掛けて保持する左右の耳掛け部とを備え、前記覆い部は、上下方向に広がる複数段のプリーツと、前記各プリーツの上下方向の広がりに伴って前記覆い部の左右両端部をアーチ状に立ち上がらせる左右の起伏部とを備え、前記各プリーツの左右両端部の所定幅は、上下方向に広がらないように折り畳まれた状態で接合されて平坦な左右のサイドシール部とされ、前記左右の起伏部は、左側の前記サイドシール部と右側の前記サイドシール部を、それぞれ左右方向に折って折り返すことにより、左右方向に伸縮する蛇腹折りにされ、その蛇腹折りによって形成された各襞と、前記サイドシール部との上端部と下端部とが、それらが互いに折り重なった状態で接合されて、前記各襞が前記サイドシール部から立ち上がるように形成されていることを特徴とする。 A mask according to a first aspect of the present invention includes a cover portion that covers at least the nose and the mouth, and left and right ear hook portions that hold the cover portion over an ear, and the cover portion is a plurality that extends in the vertical direction. A pleat of a step and left and right undulations that cause the left and right ends of the cover to rise in an arch shape as the pleats expand in the vertical direction, and the predetermined width of the left and right ends of each pleat is The left and right undulating parts are joined to each other in a folded state so as not to spread in the direction, and the left and right undulating parts are respectively connected to the left side seal part and the right side seal part in the left and right direction. By folding and folding, the bellows folds that expand and contract in the left-right direction, and the folds formed by the bellows fold, the upper end portion and the lower end portion of the side seal portion are in a state where they are folded on each other Are joined, each fold is characterized in that it is formed so as to rise from the side seal portion.

これにより、各プリーツの上下方向の広がりに伴って左右の襞が伸びるため、左右の起伏部がアーチ状に立ち上がって、鼻と口を覆う覆い部が口から浮いた状態になる。そのため、マスクをしたままで会話や呼吸が楽にできるようになる。 As a result, the left and right ridges extend as the pleats expand in the vertical direction, so that the left and right undulations rise in an arch shape, and the covering portion that covers the nose and mouth floats from the mouth. This makes it easy to talk and breathe with the mask on.

また、請求項２に記載のマスクは、請求項１に記載のマスクにおいて、蛇腹折りによって形成された前記各襞は、通気性シートで形成されていることを特徴とする。 The mask of claim 2, in the mask according to claim 1, wherein each fold formed by the folding bellows, characterized in that it is formed by breathable sheet.

これにより、通気性シートを用途に応じた透過度のものにすることにより、粉塵や花粉等が遮断できるマスクとすることができる。しかも、通気性シートが、覆い部の左右両側部に設けられているから、呼気を左右方向に排気して、冬場であっても、メガネが曇る等の問題を解消することができる。 Thereby, it can be set as the mask which can block dust, pollen, etc. by making a breathable sheet the thing of the permeability according to a use. Moreover, since the breathable sheets are provided on both the left and right sides of the cover, it is possible to exhaust the exhaled air in the left-right direction and solve the problem of glasses becoming cloudy even in winter.

また、請求項３に係るマスクは、請求項１又は２に記載のマスクにおいて、前記覆い部の各プリーツが上下方向に広がるときに、前記覆い部の左右の上部と前記鼻の両脇との間に生ずる隙間を埋める折り畳み隙間防止部がさらに設けられていることを特徴とする。 Further, the mask according to claim 3 is the mask according to claim 1 or 2 , wherein each pleat of the covering portion spreads in the vertical direction between the upper left and right sides of the covering portion and both sides of the nose. A folding gap preventing portion is further provided to fill a gap formed therebetween.

これにより、人によって鼻の形状が異なっても、覆い部の上部と鼻の両脇との間にできる隙間が、折り畳み隙間防止部によって塞がれるから、密閉性の高いマスクを提供することができる。 Thereby, even if the shape of the nose differs depending on the person, the gap formed between the upper part of the cover part and both sides of the nose is closed by the folding gap prevention part, and therefore, a mask with high sealing performance can be provided. it can.

また、請求項４に係るマスクは、請求項３に係るマスクにおいて、前記プリーツの上下方向の広がりに伴って前記襞が広がると、前記プリーツが口から離れた状態で、前記折り畳み隙間防止部と、それを除く前記覆い部の三辺が顔に密着する形状であることを特徴とする。 Further, the mask according to claim 4 is the mask according to claim 3, wherein when the fold spreads along with the vertical spread of the pleat, the folding gap preventing portion The three sides of the covering portion excluding the shape are in close contact with the face.

これにより、マスクと顔面との間にできる隙間が塞がれて、密閉性の高いマスクとすることができる。特に、マスクの左右両端部には、各プリーツを折り畳んだ状態で接合させた平坦なサイドシール部が形成されているから、覆い部が耳掛け部によって左右に引っ張られても、サイドシール部がくの字に折れずに、頬に密着する。それに加え、吸排気を左右の通気性シートに限定することができるから、通気性シートを交換したり、その透過度を変えたりすることにより、使用環境に応じたマスクとすることができる。 As a result, a gap formed between the mask and the face is closed, and a highly airtight mask can be obtained. In particular, the left and right ends of the mask are formed with flat side seals that are joined together in the folded state of each pleat. It sticks to your cheeks without breaking into a letter. In addition, since the intake / exhaust can be limited to the left and right breathable sheets, the mask according to the use environment can be obtained by replacing the breathable sheet or changing its permeability.

請求項５に係るマスクは、請求項３又は４に記載のマスクにおいて、前記折り畳み隙間防止部は、前記鼻から前記サイドシール部までの長さを有する上部が開口した袋であり、その開口した口の一方の上縁は、前記覆い部の上縁に接合され、他方の上縁は、頬に接するシート状の接合部の上縁に接合され、前記接合部は、頬に接する前記サイドシール部に接合されていることを特徴とする。
これにより、各プリーツの上下方向の広がりに伴って左右の起伏部が立ち上がると、覆い部の上縁は、サイドシール部を軸として、サイドシール部に接合された接合部から離れる。そのため、覆い部の上縁と、シート状の接合部に接合された袋の口が開き、同時に、鼻に近接する袋の先端部が、小鼻で左右方向に押されるため、覆い部の上縁と鼻の両脇との間に生ずる隙間が、袋によって完全に密閉される。 The mask according to claim 5 is the mask according to claim 3 or 4 , wherein the folding gap preventing portion is a bag having an open top having a length from the nose to the side seal portion. One upper edge of the mouth is joined to the upper edge of the covering part, the other upper edge is joined to the upper edge of the sheet-like joint part in contact with the cheek, and the joint part is in contact with the cheek. It is characterized by being joined to the part.
Thus, when the left and right undulations rise as the pleats expand in the vertical direction, the upper edge of the cover part is separated from the joint part joined to the side seal part with the side seal part as an axis. Therefore, the upper edge of the cover part and the mouth of the bag joined to the sheet-like joint part are opened, and at the same time, the front end part of the bag close to the nose is pushed left and right with the small nose. And the gap between the sides of the nose is completely sealed by the bag.

請求項６に係るマスクは、請求項５に記載のマスクにおいて、前記耳掛け部の両端部が前記接合部の上下の端部にそれぞれ取り付けられていることを特徴とする。
これにより、頬に接する接合部が耳掛け部に引っ張られて頬に密着するから、マスクの密閉度を高めることができる。 According to a sixth aspect of the present invention, in the mask according to the fifth aspect, both end portions of the ear hooking portion are respectively attached to upper and lower end portions of the joint portion.
Thereby, since the junction part which touches a cheek is pulled by the ear hook part, and closely_contact | adheres to a cheek, the sealing degree of a mask can be raised.

本発明に係るマスクによれば、プリーツを上下方向に広げるだけで、左右の起伏部が隆起して、覆い部を口から浮かせることができるから、マスクをしたまま会話や呼吸が楽にできる。また、マスクと頬との間にできる隙間を塞ぐことができるから、密閉性の高いマスクとすることができる。併せて、通気性シートにより呼気や吸気の息苦しさを解消すると共に、微小粒子の吸入を効果的に阻止して、長時間使用できるマスクを提供することができる。 According to the mask of the present invention, the left and right undulations can be raised and the cover can be lifted from the mouth simply by spreading the pleats in the vertical direction, so that conversation and breathing can be facilitated with the mask on. Further, since the gap formed between the mask and the cheek can be closed, a highly airtight mask can be obtained. In addition, it is possible to provide a mask that can be used for a long time by eliminating breathing of breath and inhalation by the breathable sheet and effectively preventing inhalation of fine particles.

以下、本発明の実施形態を、添付図面を参照しながら説明する。
図１〜図８に示すマスクは、本発明に係るマスク１の一例を示したものである。これらの図において、マスク１は、少なくとも鼻と口を覆う覆い部２と、その覆い部２を耳に掛けて保持する左右の耳掛け部７と、覆い部２の左右の上部と鼻の両脇との間に生ずる隙間を埋める折り畳み隙間防止部４とを備えている。
覆い部２は、着用者の鼻や口を覆うことが可能な形状と大きさを有し、１枚または複数枚の不織布シートを積層したものである。また、覆い部２は、上下方向に広がる複数段のプリーツ２１〜２４と、各プリーツ２１〜２４の上下方向の広がりに伴って覆い部２の左右両端部をアーチ状に立ち上がらせる左右の起伏部３とを備えている。図では、プリーツを４段設けているが、これには限定されない。また、図５では、各プリーツ２１〜２４が折り重なった時に隠れる部分を上向きに形成しているが、逆向きであっても良い。さらに、左右の起伏部３には、各プリーツ２１〜２４を横断する方向の襞３１が形成されている。また、耳掛け部７は、弾性部材で成形された紐等で耳に掛けられる形状である。
各プリーツ２１〜２４は、図７（１）に示すように、折り畳まれた状態で、それらの左右両端部が一体的に接合されることにより、平坦で上下方向に広がらないサイドシール部３２が形成されている。
左右の起伏部３は、このサイドシール部３２を、それと並行な谷折れ線（サイドシール部３２と略同じ幅を有する襞３１となる幅の内側の線）で内側に折り返して図７（２）の状態にしてから、再びそのサイドシール部３２を外側に折り返すと（図７（３）参照）、各プリーツ２１〜２４の左右端部に、それらを横断する方向の襞３１が形成される。この状態で襞３１の上下端部３３，３４と、サイドシール部３２の上下端部とを一体的に結合すれば、起伏部３が形成される。そして、各プリーツ２１〜２４を図２（ｂ）に示すように上下方向に広げると、それに伴って襞３１が伸びて、左右の起伏部３が立ち上がる。その際、サイドシール部３２が伸びないために、襞３１が扇状に広がって、起伏部３が立ち上がる。その結果、覆い部２の少なくとも三辺が顔に密着した状態で、覆い部２の中央部分が口の周りから離れるようになる。
折り畳み隙間防止部４は、装着者の鼻の両脇から前記サイドシール部３２までの長さを有する、上部が開口した袋状（図７（４）参照）であり、それらの開口した口の一方の縁は、覆い部２の上縁に接合され、前記口の他方の縁は、頬に接するシート状の接合部３５の上縁に接合されている。さらに左右の接合部３５は、頬に接する左右のサイドシール部３２に接合されて頬に密着するから、プリーツ２１〜２４が上下方向に広がって、起伏部３がサイドシール部３２から立ち上がると、袋の口が接合部３５を軸として広がり、装着者の鼻の両脇を塞ぐようになる。すなわち、覆い部２の上縁が、サイドシール部３２を軸として、サイドシール部３２に接合された接合部３５から離れるために、覆い部２の上縁と、シート状の接合部３５に接合された袋の口が開く。同時に、鼻の両脇に位置する袋の先端部が、小鼻で左右方向に押されるため、覆い部２の上縁と鼻の両脇との間に生ずる隙間が、袋によって完全に密閉されるのである。
従来のマスクは、装着時に各プリーツを上下方向に引き伸ばすと、マスクの左右両端部が、くの字に折れて、頬部６２との間に隙間が生じていた。しかし、本発明に係るマスク１では、覆い部２の左右両側部に、平坦なサイドシール部３２から立ち上がる起伏部３を設けることで、頬部６２に接する面は、形状を維持したまま頬部６２に密着する。これにより、マスク１の密閉度を高めている。
また、襞３１に通気性に優れた通気性シートを設けることで、呼気の透過度を加減することができる。これにより、密閉性の高いマスク１であっても、通気性シートを介して楽に呼吸することができる。
また、頬に接するシート状の接合部３５は、頬に密着するサイドシール部３２に接合されているから、その接合部３５の上下の端部に耳掛け部７の両端部を取り付けることで、サイドシール部３２に耳掛け部７の力が作用せずに、サイドシール部３２を頬に密着させることができる。これにより、マスク１の四辺を頬部６２に密着させることができる。
着用前のマスク１は、図２（ａ）や図７（５）に示すように、折り畳んだ状態になっている。それを着するときは、覆い部２のプリーツ２１〜２４を上下方向に広げる。すると、各プリーツ２１〜２４が図２（ｂ）に示すように隆起し、同時に左右の起伏部３が立ち上がって、覆い部２の中央部分が口の周りから離れるようになる。同時に、覆い部２の上部に設けた折り畳み隙間防止部４が広がって小鼻の両脇にできる隙間を塞ぐから、マスク１の周縁は、口を覆った状態で密閉される。したがって、両サイドの通気性シートを介して吸排気が行われるから、周囲環境に応じた透過度の通気性シート選ぶことで、安心して呼吸することができる。
以上、本発明の好ましい実施形態を説明したが、本発明は、この実施形態に制限されない。例えば図４乃至図５に示す実施形態においては、覆い部２のプリーツや伸張部２５の数や形状は実施形態に制限されない。また、覆い部２の左右両側部の、起伏部３の襞３１および接合部３５は、折り畳み型、形状、折り返しの数を多く形成してもよく、襞３１の層を増やすことも可能である。
また、覆い部２の左右両側部の起伏部３の構成は、１枚のシートから覆い部２の左右両側部を折り畳むことで、襞３１とサイドシール部３２とを形成しているが、１枚のシートであっても良いし、異なる構成であっても良い。ここでは、一枚のシートで構成した例を示しているが、これに限定されるものではない。
また、覆い部２の左右両側部の襞３１には、粉塵や花粉等に応じた通気性シート材を使用することで微小粒子の吸引を効果的に阻止できる。さらに、通気性に優れた通気性シート材は、多層構造シート材、または、別体の構造であっても良いし、一体の構造であっても良い。さらに、折り畳み隙間防止部４は、形状を変えることが可能であり、ここに示した実施形態に制限されない。
また、マスク１の構成は、覆い部２と起伏部３と接合部３５と折り畳み隙間防止部４と耳掛け部７と、の組み合わせを変えることが可能であり、ここに示した実施形態に制限されない。 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
The mask shown in FIGS. 1-8 shows an example of the mask 1 which concerns on this invention. In these drawings, the mask 1 includes a cover 2 that covers at least the nose and mouth, left and right ear hooks 7 that hold the cover 2 on the ears, and both the left and right upper portions of the cover 2 and the nose. The folding gap prevention part 4 which fills the gap produced between the sides is provided.
The cover part 2 has a shape and size that can cover the wearer's nose and mouth, and is formed by laminating one or a plurality of non-woven sheets. The cover portion 2 includes a plurality of pleats 21 to 24 that extend in the vertical direction, and left and right undulation portions that cause the left and right ends of the cover portion 2 to rise in an arch shape as the pleats 21 to 24 expand in the vertical direction. 3 is provided. In the figure, four pleats are provided, but the present invention is not limited to this. Moreover, in FIG. 5, although the part which is hidden when each pleats 21-24 are folded up is formed upward, it may be reverse. Further, the left and right undulations 3 are formed with ridges 31 in a direction crossing the pleats 21 to 24. The ear hook 7 has a shape that can be hung on the ear by a string formed of an elastic member.
As shown in FIG. 7 (1), each pleat 21 to 24 has a flat side seal portion 32 that does not spread in the vertical direction by integrally joining the left and right ends thereof in a folded state. Is formed.
The left and right undulations 3 fold the side seal part 32 inward along a valley fold line parallel to the side seal part 32 (a line on the inner side of the width of the flange 31 having substantially the same width as the side seal part 32). When the side seal portion 32 is turned back to the outside again (see FIG. 7 (3)), the ridges 31 are formed at the left and right end portions of the pleats 21 to 24 in the direction crossing them. In this state, when the upper and lower end portions 33 and 34 of the flange 31 and the upper and lower end portions of the side seal portion 32 are integrally coupled, the undulating portion 3 is formed. And if each pleat 21-24 is spread up and down as shown in FIG.2 (b), the collar 31 will be extended in connection with it and the right and left undulation part 3 will stand up. At that time, since the side seal portion 32 does not extend, the flange 31 spreads in a fan shape and the undulating portion 3 rises. As a result, the central portion of the cover 2 is separated from the periphery of the mouth in a state where at least three sides of the cover 2 are in close contact with the face.
The folding gap prevention part 4 has a length from both sides of the wearer's nose to the side seal part 32 and has a bag shape (see FIG. 7 (4)) with an open top. One edge is joined to the upper edge of the cover 2, and the other edge of the mouth is joined to the upper edge of the sheet-like joint 35 that contacts the cheek. Furthermore, since the left and right joint portions 35 are joined to the left and right side seal portions 32 that are in contact with the cheeks and are in close contact with the cheeks, when the pleats 21 to 24 spread in the vertical direction and the undulating portion 3 rises from the side seal portions 32, The mouth of the bag spreads with the joint 35 as an axis, and closes both sides of the wearer's nose. That is, the upper edge of the cover portion 2 is separated from the joint portion 35 joined to the side seal portion 32 with the side seal portion 32 as an axis, so that the upper edge of the cover portion 2 and the sheet-like joint portion 35 are joined. The opened bag mouth opens. At the same time, since the tip of the bag located on both sides of the nose is pushed in the left and right direction with a small nose, the gap formed between the upper edge of the cover 2 and both sides of the nose is completely sealed by the bag. It is.
In the conventional mask, when each pleat is stretched in the vertical direction at the time of wearing, the left and right end portions of the mask are folded into a dogleg shape, and a gap is formed between the cheek portion 62. However, in the mask 1 according to the present invention, the undulating portions 3 rising from the flat side seal portion 32 are provided on the left and right side portions of the cover portion 2, so that the surface in contact with the cheek portion 62 maintains the shape of the cheek portion. It sticks to 62. Thereby, the sealing degree of the mask 1 is raised.
Moreover, the permeability | transmittance of an expiration can be adjusted by providing the air permeable sheet excellent in air permeability in the collar 31. FIG. Thereby, even if it is the mask 1 with high airtightness, it can breathe easily through a breathable sheet.
In addition, since the sheet-like joint portion 35 in contact with the cheek is joined to the side seal portion 32 that is in close contact with the cheek, by attaching both ends of the ear hooking portion 7 to the upper and lower ends of the joint portion 35, The side seal portion 32 can be brought into close contact with the cheek without the force of the ear hook portion 7 acting on the side seal portion 32. Thereby, the four sides of the mask 1 can be brought into close contact with the cheek 62.
The mask 1 before wearing is in a folded state as shown in FIGS. 2 (a) and 7 (5). When wearing it, the pleats 21 to 24 of the cover part 2 are spread vertically. Then, the pleats 21 to 24 are raised as shown in FIG. 2B, and the left and right undulations 3 are raised at the same time, so that the central portion of the cover 2 is separated from the periphery of the mouth. At the same time, the folding gap prevention part 4 provided on the upper part of the cover part 2 spreads to close the gaps formed on both sides of the nose, so that the periphery of the mask 1 is sealed with the mouth covered. Therefore, since intake and exhaust are performed through the air-permeable sheets on both sides, it is possible to breathe in peace by selecting a gas-permeable sheet having a permeability according to the surrounding environment.
As mentioned above, although preferable embodiment of this invention was described, this invention is not restrict | limited to this embodiment. For example, in the embodiment shown in FIG. 4 to FIG. Further, the ridges 31 and the joints 35 of the undulating portion 3 on both the left and right sides of the cover portion 2 may be formed with a large number of folding types, shapes, and folds, and the number of layers of the ridges 31 can be increased. .
In addition, the structure of the undulating portions 3 on both the left and right sides of the cover portion 2 forms the ridge 31 and the side seal portion 32 by folding the left and right side portions of the cover portion 2 from one sheet. It may be a single sheet or a different configuration. Here, an example of a single sheet is shown, but the present invention is not limited to this.
Moreover, the suction | attraction | suction of microparticles | fine-particles can be effectively prevented by using the air permeable sheet material according to dust, pollen, etc. for the ridges 31 on the left and right sides of the cover portion 2. Further, the breathable sheet material having excellent breathability may be a multilayer structure sheet material, a separate structure, or an integral structure. Furthermore, the folding gap prevention unit 4 can be changed in shape and is not limited to the embodiment shown here.
Moreover, the structure of the mask 1 can change the combination of the cover part 2, the undulation part 3, the junction part 35, the folding clearance prevention part 4, and the ear hook part 7, and is limited to the embodiment shown here. Not.
