Description

本発明は、マスク用フィルタ材とこれを用いたマスクに関し、着脱が容易でありながら、口や鼻孔の周囲を隙間なく覆うことができ、呼・吸気からウイルスや花粉、塵埃などの微細な異物を効率的に除去できる、マスク用フィルタ材とこれを用いたマスクに関する。   The present invention relates to a filter material for a mask and a mask using the same, and can easily cover and detach the mouth and nostrils without any gaps, and from a call / inhalation to a minute foreign matter such as virus, pollen, dust, etc. The present invention relates to a mask filter material and a mask using the same.

近年、花粉症の患者が増大しており、社会的にも大きな問題となってきている。また、新型インフルエンザウイルスのように、抗体保持者が少なく、爆発的に感染が広がる場合もある。これらのウイルスや花粉から身を守る方法の1つとして、衛生マスクの使用が考えられる。   In recent years, the number of patients with hay fever has increased and has become a major social problem. In addition, like the new influenza virus, there are few antibody holders and the infection may spread explosively. One way to protect yourself from these viruses and pollen is to use a sanitary mask.

従来、上記の衛生マスクとしては、ガーゼや木綿布などよりなるマスク本体と、その両側に付設した耳掛け部などの保持部材とを備えており、マスク本体の内面にガーゼを折り畳んだ当て材を配置したものがある。しかし、この当て材のみではウイルスなどの侵入、放散や、花粉、塵埃などの微細な異物の侵入を阻止することが容易でない。そこでこれを解消するため、殺菌性を有する湿式フィルタ材シートを上記の当て材の中間に介装したものが提案されている(例えば、特許文献1参照、以下、従来技術1という。)。   Conventionally, the sanitary mask includes a mask body made of gauze, cotton cloth, etc., and holding members such as ear hooks attached to both sides of the mask body. There is something arranged. However, it is not easy to prevent intrusion and diffusion of viruses and the like, and entry of fine foreign matters such as pollen and dust, only with the contact material. Therefore, in order to solve this problem, there has been proposed a wet filter material sheet having sterilization properties interposed between the above-mentioned contact materials (for example, refer to Patent Document 1 and hereinafter referred to as Prior Art 1).

上記の従来技術1のマスクは、装着時に上記の保持部材で後方へ引張ることにより、マスク本体の内側表面を装着者の顔面へ押圧してある。しかし、このマスク本体は薄いシート状の布帛で形成されているので、保持部材の引張り力だけでは、内側表面の周縁部分を装着者の顔面に隙間なく密着させることが容易でない。そしてこの周縁部分で顔面との間に隙間が形成されると、装着者の呼気や吸気がこの隙間を流通する問題がある。特に、装着者が咳やくしゃみをすると、その勢いでマスク本体が顔面から浮き上がり、上記の隙間が一層拡大することとなる。このため、装着者の呼気や吸気は、上記のマスク本体や当て材以外に、マスク本体と顔面との間に形成された隙間をも通じて流通し、上記の湿式フィルタ材シート等に抗菌作用を持たせたとしても、インフルエンザウイルスや花粉、塵埃などを効率よく捕捉することができない問題があつた。   The mask of the above prior art 1 presses the inner surface of the mask main body against the face of the wearer by pulling backward with the holding member at the time of wearing. However, since the mask main body is formed of a thin sheet-like fabric, it is not easy to bring the peripheral portion of the inner surface into close contact with the wearer's face without a gap only by the pulling force of the holding member. If a gap is formed between the peripheral edge portion and the face, there is a problem that the exhalation or inhalation of the wearer flows through the gap. In particular, when the wearer coughs or sneezes, the mask body rises from the face with the momentum, and the gap is further enlarged. Therefore, exhalation and inhalation of the wearer circulates through a gap formed between the mask main body and the face in addition to the mask main body and the covering material, and has antibacterial action on the wet filter material sheet and the like. However, even if it was provided, there was a problem that influenza virus, pollen, dust, etc. could not be captured efficiently.

上記の問題点を解消するため、例えば上記の保持部材を、装着者の頭部の後方へ回して強い力でマスク本体を引張ることにより、マスク本体の周縁を装着者の顔面に確りと密着させるマスクが提案されている(例えば、特許文献2参照、以下、従来技術2という。)。また、マスク本体の周縁を装着者の顔面に粘着剤等で接着させることにより、気密状に固定するマスクが提案されている(例えば、特許文献3参照、以下、従来技術3という。)。さらに、マスクの内側表面の上端に立体形状のパットを固定して、装着者の鼻梁の両側にできる隙間を遮断するマスクが提案されている(例えば、特許文献4参照、以下、従来技術4という。)。   In order to solve the above problems, for example, by rotating the holding member to the back of the wearer's head and pulling the mask body with a strong force, the peripheral edge of the mask body is firmly attached to the wearer's face. A mask has been proposed (see, for example, Patent Document 2, hereinafter referred to as Prior Art 2). Further, a mask that is fixed in an airtight manner by adhering the periphery of the mask body to the face of the wearer with an adhesive or the like has been proposed (for example, see Patent Document 3 and hereinafter referred to as Prior Art 3). Furthermore, a mask has been proposed in which a three-dimensional pad is fixed to the upper end of the inner surface of the mask to block a gap formed on both sides of the wearer's nasal bridge (see, for example, Patent Document 4; .).

しかし上記の従来技術2のマスクにあっては、マスク本体の周縁部分を装着者の顔面へ確りと密着させるため、上記の保持部材は強い引張り力を有することから、これを頭部の後方へ回す装着操作やこれを取り外す操作が容易でない問題がある。さらに、強い力でマスク本体の周縁部分を顔面に押圧するため、その顔面にくっきりとした装着跡が付く問題もある。   However, in the mask of the above prior art 2, since the holding member has a strong pulling force in order to bring the peripheral portion of the mask body into close contact with the face of the wearer, this is moved to the rear of the head. There is a problem that it is not easy to turn and remove it. Furthermore, since the peripheral portion of the mask body is pressed against the face with a strong force, there is a problem that a clear wearing trace is attached to the face.

一方、上記の従来技術3のマスクにあっては、装着したのち取り外すとその接着力が低下しているので、再装着の際に密着させることが容易でなく、装着者の顔面との間に隙間を生じて、呼・吸気がその隙間を流通する問題がある。また、マスクは飲食や会話の際にしばしば着脱されることがあるが、その都度、接着力の優れた新しいマスクに交換することは、装着者に大きなコスト負担となる問題もある。   On the other hand, in the mask of the above-described prior art 3, since the adhesive strength is reduced when the mask is removed after being mounted, it is not easy to make close contact at the time of re-mounting, and between the face of the wearer. There is a problem in that a gap is generated and the call / intake flows through the gap. In addition, the mask is often attached and detached during eating and drinking, and each time it is replaced with a new mask with excellent adhesive strength, there is a problem that a large cost is imposed on the wearer.

また上記の従来技術4のマスクにあっては、装着者の鼻梁の両側にできる隙間を遮断できるものの、人の顔は千差万別であり、部分的に立体形状のパットを付設しただけでは、マスクでの周縁部分を全周に亘って隙間なく密着させることが容易でない。このため、前記の従来技術1と同様、装着者の頬とマスク本体の内側表面との間に隙間が形成され、この隙間を介して装着者の呼・吸気が流通する問題がある。   Moreover, in the mask of the above-mentioned prior art 4, although the gap formed on both sides of the wearer's nasal bridge can be blocked, the human face is various, and only by attaching a three-dimensional pad partly In addition, it is not easy to bring the peripheral edge of the mask into close contact with the entire circumference without any gaps. For this reason, there is a problem that a gap is formed between the cheek of the wearer and the inner surface of the mask body, and the caller's call / intake is circulated through the gap, as in the prior art 1.

本発明の技術的課題は上記の問題点を解消し、着脱が容易でありながら、口や鼻孔の周囲を隙間なく覆うことができ、呼・吸気からウイルスや花粉、塵埃などの微細な異物を効率的に除去できる、マスク用フィルタ材とこれを用いたマスクを提供することにある。   The technical problem of the present invention is to solve the above-mentioned problems, and can easily cover and detach the mouth and nostrils without gaps, so that fine foreign substances such as viruses, pollen and dust can be removed from the call and inhalation. An object of the present invention is to provide a mask filter material and a mask using the same that can be efficiently removed.

本発明は上記の課題を解決するために、例えば本発明の実施の形態を示す図1から図3に基づいて説明すると、次のように構成したものである。
即ち本発明1はマスク用フィルタ材に関し、装着者の顔面とマスク本体(2)との間に配置されるフィルタ材(4)であって、少なくとも周縁部分(7)が、復元可能に厚さ方向へ圧縮変形できるクッション性と、装着者の呼・吸気が通過できる通気性とを有し、上記のマスク本体(2)の装着時は、周縁部分(7)が装着者の口と鼻孔を取り囲む状態に配置され、そのマスク本体(2)の装着力で装着者の顔面側へ押圧されて、復元可能に厚さ方向へ圧縮変形することを特徴とする。
In order to solve the above problems, the present invention will be described as follows, for example, based on FIGS. 1 to 3 showing an embodiment of the present invention.
That is, the present invention relates to a filter material for a mask, which is a filter material (4) disposed between the face of the wearer and the mask main body (2), and at least the peripheral portion (7) is restoreably thick. It has a cushioning property that can compressively deform in the direction and a breathability that allows the wearer's call and inhalation to pass through. When the mask body (2) is worn, the peripheral portion (7) covers the wearer's mouth and nostrils. It is arranged in a surrounding state, and is pressed against the face side of the wearer with the mounting force of the mask main body (2), and is compressively deformed in the thickness direction so that it can be restored.

また、本発明2はマスクに関し、装着者の口と鼻孔を覆うマスクであって、マスク本体(2)と、このマスク本体(2)を装着者の顔面前方の所定位置に保持する保持部材(3)と、このマスク本体(2)と装着者の顔面との間に配置される上記の本発明1のマスク用フィルタ材(4)とを備えることを特徴とする。   The present invention 2 also relates to a mask, which is a mask that covers a wearer's mouth and nostril. The mask main body (2) and a holding member that holds the mask main body (2) in a predetermined position in front of the wearer's face ( 3) and the mask filter material (4) of the present invention 1 disposed between the mask body (2) and the face of the wearer.

また本発明3はマスクに関し、装着者の口と鼻孔を覆うマスクであって、装着者の顔面と対面する側の少なくとも周縁部分にフィルタ材(4)を備え、このフィルタ材(4)は、復元可能に厚さ方向へ圧縮変形できるクッション性と、装着者の呼・吸気が通過できる通気性とを有することを特徴とする。   The present invention 3 also relates to a mask, which is a mask that covers the mouth and nostril of the wearer, and is provided with a filter material (4) at least at the peripheral portion on the side facing the wearer's face. It has a cushioning property that can be compressed and deformed in the thickness direction so that it can be restored, and a breathability that allows a wearer's call / inhalation to pass through.

上記のマスク用フィルタ材を備えたマスクを装着すると、マスク用フィルタ材はマスク本体の装着力で装着者の顔面側へ押圧されるが、このフィルタ材はクッション性があるので、装着者の顔面に沿って圧縮変形し、これによりそのフィルタ材の内側表面が装着者の顔面に隙間なく密着する。装着者の咳やくしゃみでマスク本体が顔面から離隔しようとすると、上記のフィルタ材は厚さ方向に復元し、装着者の顔面との間の隙間の形成が防止される。ここで、上記のクッション性とは、装着者の顔面の凹凸を吸収できる程度以上の、復元可能な圧縮性を備えていることをいう。   When a mask equipped with the above-described mask filter material is worn, the mask filter material is pressed toward the face of the wearer by the wearing force of the mask body, but this filter material has cushioning properties, so the face of the wearer , So that the inner surface of the filter material is in close contact with the face of the wearer without any gaps. When the mask body tries to separate from the face due to the wearer's coughing or sneezing, the filter material is restored in the thickness direction, and formation of a gap with the wearer's face is prevented. Here, the above cushioning property means that it has a compressible property that can be restored to a level that can absorb irregularities on the wearer's face.

装着者の吸気は、マスク本体とマスク用フィルタ材内とを順に経て、口や鼻孔から吸い込まれるほか、マスク本体の周縁部分と顔面との間の隙間を通過した外気が、フィルタ材の周縁部分からフィルタ材の内部を経て口や鼻孔から吸い込まれる。一方、装着者の呼気は、マスク用フィルタ材内とマスク本体を順に経て外部へ放出されるほか、フィルタ材内を通過したのちそのフィルタ材の周縁部分から、マスク本体の周縁部分と顔面との間の隙間を通過して外部へ放出される。   The wearer's inspiration passes through the mask body and the mask filter material in order, and is sucked in through the mouth and nostril, and outside air that has passed through the gap between the periphery of the mask body and the face becomes the periphery of the filter material. From the mouth and nostril through the inside of the filter material. On the other hand, the exhalation of the wearer is discharged to the outside through the filter material for the mask and the mask body in order, and after passing through the filter material, from the peripheral part of the filter material, the peripheral part of the mask body and the face It passes through the gap between them and is discharged to the outside.

上記のフィルタ材は、装着時に周縁部分が口と鼻孔を取り囲む状態に配置されておればよく、外側表面がマスク本体の内側表面に密着している場合は、中間部分に開口部が形成されていてもよい。この場合、装着者の呼・吸気は、口や鼻孔の前面のマスク本体を通過するほか、フィルタ材の内部を経たのち、マスク本体の周縁部分と顔面との間の隙間を通過する。このため、マスク本体も優れた濾過性能を備えると好ましく、抗菌加工が施されているとさらに好ましい。これに対し、上記のフィルタ材が中間部分に開口部を備えていない場合は、装着者の呼・吸気は必ずこのフィルタ材の内部を通過するので、マスク本体は、例えばネットからなるシート材などのように、濾過性能が低くてもよく、さらに抗菌加工等が施されていなくてもよい。   The filter material may be arranged so that the peripheral portion surrounds the mouth and nostril when attached, and when the outer surface is in close contact with the inner surface of the mask body, an opening is formed in the intermediate portion. May be. In this case, the wearer's call / intake passes through the mask body in front of the mouth and nostrils, and after passing through the inside of the filter material, passes through the gap between the peripheral portion of the mask body and the face. For this reason, it is preferable that the mask body also has excellent filtration performance, and it is more preferable that antibacterial processing is applied. On the other hand, if the filter material does not have an opening in the middle portion, the wearer's call / intake always passes through the inside of the filter material, so the mask body is, for example, a sheet material made of a net, etc. As described above, the filtration performance may be low and antibacterial processing may not be applied.

上記のフィルタ材は、装着者の顔面に良好に沿うので、装着前は特定の形状に限定されず、例えば平面状であってもよい。しかし、人の顔は、特に鼻梁の両側で段差が大きいので、このような段差等に対応した立体形状であると、一層良好に顔面に沿って隙間なく密着でき、好ましい。
また、中央部分が装着者の顔面から離隔する方向に湾曲した立体形状に形成してあり、この中央部分と装着者の顔面との間に空間が形成してあると、装着者の唇とフィルタ材の内側表面とが離隔するので、口紅などがフィルタ材に付く虞を低減できるうえ、その空間を介してマスクの全面を介して通気できるので、装着者は楽に呼吸ができて好ましい。
Since said filter material follows a wearer's face favorably, it is not limited to a specific shape before mounting | wearing, For example, planar shape may be sufficient. However, since the human face has a large step particularly on both sides of the nose bridge, it is preferable that the human face has a three-dimensional shape corresponding to such a step or the like because it can be more closely adhered to the face without a gap.
In addition, when the central portion is formed in a three-dimensional shape curved in a direction away from the wearer's face, and a space is formed between the central portion and the wearer's face, the wearer's lips and the filter Since it is separated from the inner surface of the material, it is possible to reduce the possibility of lipstick and the like adhering to the filter material and to allow ventilation through the entire surface of the mask through the space.

上記のフィルタ材は、所望のクッション性と通気性を備えておればよく、特定の材質に限定されず、例えば連続気泡の発泡体などであってもよいが、不織布であると、優れたクッション性と通気性を容易に備えることができて好ましい。
上記の不織布は、特定の寸法や密度のものに限定されないが、例えば、装着前の少なくとも周縁部分での空隙率が90〜99%程度であると異物を効率的に捕捉できるうえ、良好に通気できるので好ましく、さらに95%程度であると一層良好に通気できて装着者が息苦しさを感じることがなく、より好ましい。
The filter material is not limited to a specific material as long as it has a desired cushioning property and air permeability, and may be, for example, an open-celled foam or the like. And air permeability can be easily provided.
The non-woven fabric is not limited to a specific size or density. For example, when the void ratio at least at the peripheral portion before mounting is about 90 to 99%, foreign matter can be efficiently captured and air can be well ventilated. Since it is possible, it is preferable, and it is more preferable that it is about 95%, since it can ventilate better and a wearer does not feel breathlessness.

また上記の不織布を構成する繊維の直径は、特定の寸法のものに限定されないが、過剰に細いものを使用すると通気性を阻害する虞があるので、通常、10μm以上のものが用いられ、より好ましくは20μm以上のものが用いられる。さらに上記の不織布は、装着前の周縁部分での厚みが5〜20mmであると、クッション性に優れ、装着者の顔面との間に隙間を形成することなく密着できるので好ましい。   In addition, the diameter of the fiber constituting the nonwoven fabric is not limited to a specific size, but if an excessively thin one is used, there is a risk of impairing air permeability. Those having a thickness of 20 μm or more are preferably used. Furthermore, it is preferable that the above-mentioned nonwoven fabric has a thickness of 5 to 20 mm at the peripheral edge before wearing because it is excellent in cushioning properties and can be in close contact with the face of the wearer without forming a gap.

なお上記の不織布の空隙率は、次式で算出される。
空隙率(%)={1−目付(g/m2)÷厚さ(mm)÷1000÷比重(g/cm)}×100(%) ……(式1)
ここで、上記の比重は、不織布を構成する各繊維の比重の、混紡比率に応じた加重平均値が用いられる。
In addition, the porosity of said nonwoven fabric is computed by following Formula.
Porosity (%) = {1 per unit area (g / m 2 ) ÷ thickness (mm) ÷ 1000 ÷ specific gravity (g / cm 3 )} x 100 (%) …… (Formula 1)
Here, as the specific gravity, a weighted average value according to the blending ratio of specific gravity of each fiber constituting the nonwoven fabric is used.

上記の不織布を構成する繊維としては、綿などの天然繊維、レーヨンなどの化学繊維、ポリエステルなどの合成繊維のいずれであってもよく、これらを任意に組み合わせたものであってもよい。例えば高捲縮性の合成繊維を用いると、クッション性と通気性を良好にできて好ましく、特にコンジュゲートタイプのポリエステルなどの合成繊維を用いると、クッション性と通気性を一層良好にできてさらに好ましい。
また上記の不織布は、例えばポリエステル共重合体などの、低融点熱可塑性合成繊維を含有すると、その低融点熱可塑性合成繊維を溶融することで、これを介して他の繊維を互いに接着することができるので、不織布全体の強度を向上できるうえ、クッション性と通気性を保持しながら、毛羽立ち防止(いわゆる、リントフリー)の効果をも有し、しかも、その不織布を所望の立体形状に容易に成形することができて好ましい。
As a fiber which comprises said nonwoven fabric, any of natural fibers, such as cotton, chemical fibers, such as rayon, and synthetic fibers, such as polyester, may be combined arbitrarily. For example, it is preferable to use a highly crimped synthetic fiber because the cushioning property and air permeability can be improved. Particularly, when a synthetic fiber such as a conjugate type polyester is used, the cushioning property and air permeability can be further improved. preferable.
In addition, when the above-mentioned nonwoven fabric contains a low-melting thermoplastic synthetic fiber such as a polyester copolymer, the low-melting thermoplastic synthetic fiber can be melted to bond other fibers to each other through this. As a result, the overall strength of the nonwoven fabric can be improved, and while maintaining cushioning and breathability, it has the effect of preventing fuzz (so-called lint-free), and the nonwoven fabric can be easily formed into the desired three-dimensional shape. This is preferable.

上記のフィルタ材は、ウイルスや花粉、塵埃などの異物を捕捉できるものであればよいが、少なくとも呼・吸気が通過する部位に抗菌剤や殺菌剤を坦持させてあると、呼気や吸気に含まれるウイルス、細菌などを良好に無害化でき、或いは補足したウイルス等の増殖を防止できて好ましい。   The filter material is not limited as long as it can capture foreign substances such as viruses, pollen, and dust, but at least if antibacterial and bactericidal agents are carried in the area where exhaled and inhaled air passes, It is preferable because the contained virus, bacteria, etc. can be detoxified well, or the growth of the supplemented virus, etc. can be prevented.

上記の抗菌剤は、無機抗菌剤と有機抗菌剤とのいずれであってもよく、特定の抗菌剤に限定されない。
無機抗菌剤としては、例えば、銀ブロムまたはヨード錯塩、あるいは銀、銅、亜鉛、白金、ニッケル、コバルト、クロム、チタン等の金属イオン、またはそれら金属の酸化物、水酸化物などの金属化合物等が挙げられる。この中で銀の金属イオンが好ましい。これらの無機抗菌剤は1種類を単独で用いてもよいし、複数種類を組み合わせて用いてもよい。
The antibacterial agent may be either an inorganic antibacterial agent or an organic antibacterial agent, and is not limited to a specific antibacterial agent.
Examples of inorganic antibacterial agents include silver bromide or iodine complex salts, metal ions such as silver, copper, zinc, platinum, nickel, cobalt, chromium, titanium, or metal compounds such as oxides and hydroxides of these metals. Is mentioned. Of these, silver metal ions are preferred. These inorganic antibacterial agents may be used alone or in combination of a plurality of types.

上記の有機抗菌剤としては、例えば、第4級アンモニウム、チアペンタゾール、バイアジンあるいはキチン、キトサンの如きポリカチオン等が挙げられる。この中で第4級アンモニウム、キトサンが好ましい。これらの有機抗菌剤は1種類を単独で用いてもよいし、複数種類を組み合わせて用いてもよい。さらには無機抗菌剤と有機抗菌剤とを組み合わせて用いることも可能である。   Examples of the organic antibacterial agent include quaternary ammonium, thiapentazole, viaazine, or polycation such as chitin and chitosan. Of these, quaternary ammonium and chitosan are preferable. One type of these organic antibacterial agents may be used alone, or a plurality of types may be used in combination. Furthermore, it is also possible to use a combination of an inorganic antibacterial agent and an organic antibacterial agent.

上記の抗菌剤や殺菌剤は、任意の方法で上記のフィルタ材に坦持させることができる。しかし、上記のフィルタ材がペクチンを含むセルロース系繊維を含有している場合には、例えば特開2004−277901号公報に記載のように処理することで、このセルロース系繊維に上記の抗菌剤等を強固に坦持することができ、安定的に且つ持続的に抗菌剤等をセルロース繊維に結合させることができるので、好ましい。なお上記の抗菌剤等を坦持させる処理とは、具体的には、例えば、ペクトセルロース繊維またはペクトセルロース繊維布帛を、ペクトセルロース繊維中に存在するペクチン含有量が処理前のペクチン含有量に対して1〜80質量%になるように、酸、塩基、それらの塩類、キレート剤およびペクチン分解酵素から成る群から選ばれる少なくとも一つの化学物質で処理してペクチン含有量を減少させ、処理したペクトセルロース繊維またはペクトセルロース繊維布帛にイオン性の無機化合物抗菌剤や有機化合物抗菌剤等を担持させる方法である。   Said antibacterial agent and disinfectant can be carried on said filter material by arbitrary methods. However, when the filter material contains a cellulosic fiber containing pectin, the antibacterial agent is added to the cellulosic fiber by, for example, treating as described in JP-A-2004-277901. Can be firmly supported, and an antibacterial agent or the like can be bound to the cellulose fiber stably and continuously, which is preferable. The treatment for carrying the antibacterial agent or the like specifically refers to, for example, pectincellulose fiber or pectincellulose fiber fabric, in which the pectin content present in the pectincellulose fiber is compared to the pectin content before treatment. Treated with at least one chemical selected from the group consisting of acids, bases, salts thereof, chelating agents and pectin-degrading enzymes so as to reduce the pectin content, In this method, an ionic inorganic compound antibacterial agent, an organic compound antibacterial agent, or the like is supported on cellulose fiber or pectcellulose fiber fabric.

なお、フィルタ材に占める上記のセルロース系繊維は、含有率が好ましくは10〜70重量%であり、他は通常のポリエステルなどの合成繊維であってもよい。   In addition, said cellulosic fiber which occupies for a filter material becomes like this. Preferably content rate is 10 to 70 weight%, and others may be synthetic fibers, such as normal polyester.

上記のフィルタ材は、少なくとも片側の表面に、伸縮性と通気性とを備えた保護層を備えると、例えば抗菌加工などの際のハンドリングを良好にできて好ましい。特にこの保護層を装着者の顔面と対面する表面に形成してあると、フィルタ材の毛羽立ちを抑え、装着者の顔面に対して肌触りを良好にできる利点がある。これらの保護層は、ニット材や高密度不織布などの任意の材料で形成され、ライニング、ラミネート、表面加工など、任意の加工によりフィルタ材と一体化される。   It is preferable that the above filter material is provided with a protective layer having stretchability and air permeability on at least one surface, for example, because the handling during antibacterial processing can be improved. In particular, when this protective layer is formed on the surface facing the wearer's face, there is an advantage that fuzz of the filter material can be suppressed and the feel of the wearer's face can be improved. These protective layers are formed of an arbitrary material such as a knit material or a high-density nonwoven fabric, and are integrated with the filter material by an arbitrary process such as lining, laminating, or surface processing.

上記のフィルタ材は、マスク本体とは別体に形成されていてもよく、この場合は既存のマスクをマスク本体として採用でき、安価に実施することができる。しかし上記のフィルタ材はマスク本体に固定してあってもよく、この場合はマスクの装着を一層簡略にできて好ましい。このフィルタ材とマスク本体との固定は、例えば面ファスナ等で着脱可能に固定してもよく、或いは接着剤や縫製などで離脱不能に固定してもよい。   The filter material may be formed separately from the mask body. In this case, an existing mask can be adopted as the mask body and can be implemented at low cost. However, the above filter material may be fixed to the mask body, and in this case, it is preferable because the mask can be further simplified. The filter material and the mask body may be fixed detachably with, for example, a hook-and-loop fastener or the like, or may be fixed so as not to be detached with an adhesive or sewing.

上記のマスク本体は、不織布や織布などからなる汎用のマスクが一般に使用されるが、このマスク本体は、上記のフィルタ材を装着者の顔面側へ押圧できる押圧部材であればよく、特定の材質や形状のものに限定されない。またフィルタ材で異物を捕捉できるので、マスク本体の濾過性能や抗菌性能は必須でない。例えば、ネットなどの伸縮性を備えた平面状の布帛であってもよく、中央が装着者の顔面から離れる方向に湾曲した曲面状の不織布などであってもよい。   As the mask body, a general-purpose mask made of a nonwoven fabric or a woven fabric is generally used. The mask body may be a pressing member that can press the filter material toward the face of the wearer. It is not limited to the material or shape. Moreover, since the foreign material can be captured by the filter material, the filtering performance and antibacterial performance of the mask body are not essential. For example, a flat fabric having elasticity such as a net may be used, or a curved nonwoven fabric having a center curved in a direction away from the face of the wearer.

また、上記のマスク本体を装着者の顔面前方の所定位置に保持する保持部材は、特定の形状や材質のものに限定されず、例えば、ゴム弾性を備えた紐や、マスク本体の両端に延設した保持部などで形成され、装着者の耳に掛けるように構成してもよく、或いは、装着者の頭部の後方を通過させるように装着するものであってもよい。   Further, the holding member for holding the mask main body at a predetermined position in front of the face of the wearer is not limited to a specific shape or material, and for example, a string having rubber elasticity or extending to both ends of the mask main body. It may be formed by a holding portion or the like provided and hung on the wearer's ear, or may be worn so as to pass behind the head of the wearer.

本発明のマスク用フィルタ材とマスクは、上記のように構成され作用することから、次の効果を奏する。   Since the mask filter material and the mask of the present invention are configured and act as described above, the following effects can be obtained.

(1)上記のフィルタ材はクッション性があるので、装着者の顔面に沿って圧縮変形することにより、内側表面が装着者の顔面に容易に隙間なく密着し、装着者の顔面との間の隙間の形成を確実に防止できる。しかも、復元性があるうえ、通気性が高いので、咳やくしゃみをした場合も、装着者の顔面に良好に密着させておくことができる。これにより、装着者の口や鼻孔の周囲をフィルタ材で隙間なく覆うことができる。   (1) Since the above-mentioned filter material has a cushioning property, by compressing and deforming along the wearer's face, the inner surface easily adheres to the wearer's face without a gap, and between the face of the wearer The formation of a gap can be reliably prevented. In addition, since it is restorable and highly breathable, it can be kept in good contact with the wearer's face even when coughing or sneezing. Thereby, the circumference | surroundings of a wearer's mouth and nostril can be covered with a filter material without a gap.

(2)呼気や吸気はフィルタ材内を必ず通過するので、その呼・吸気に含まれるウイルスや花粉、塵埃などの異物を効率的に捕捉して除去することができ、装着者が吸い込むことや外部へ放出することを抑制できる。   (2) Since exhaled air and inhaled air always pass through the filter material, foreign substances such as viruses, pollen and dust contained in the exhaled air and inhaled air can be efficiently captured and removed. Release to the outside can be suppressed.

(3)上記のフィルタ材はクッション性を備えるので、軽い押圧力で装着者の顔面に沿うことができ、従って保持部材を強力に引張る必要がないので、装着者は簡単に装着でき、取り外しも容易である。また、装着者の口や鼻孔の周囲を隙間なく覆えるものでありながら、前記の従来技術2と異なって、装着者の顔面に装着跡が付く虞がない。   (3) Since the above filter material has cushioning properties, it is possible to follow the wearer's face with a light pressing force, and therefore it is not necessary to pull the holding member strongly. Easy. Moreover, unlike the prior art 2, the wearer's face and the nostril can be covered without any gaps, and there is no possibility that the wearer's face will be marked.

(4)フィルタ材は、マスク本体の押圧力で装着者の顔面に沿うので、前記の従来技術3とは異なって接着剤などを用いる必要がなく、取り外したのちも確実に且つ容易に再装着することができる。   (4) Since the filter material follows the face of the wearer with the pressing force of the mask body, unlike the prior art 3, it is not necessary to use an adhesive or the like, and it is securely and easily reattached after removal. can do.

(5)フィルタ材はマスク本体がある前方だけでなく、フィルタ材の周縁部分の全周に亘って、マスク本体と顔面との間に形成される隙間からも、外気を吸入でき、或いは外部へ呼気を排出できる。このため、マスク全体の通気面積が大きいので、装着者は楽に呼吸をすることができる。   (5) The filter material can inhale outside air not only from the front where the mask body is located, but also from the gap formed between the mask body and the face over the entire periphery of the filter material, or to the outside. Exhale can be discharged. For this reason, since the ventilation area of the whole mask is large, the wearer can breathe easily.

以下、本発明の実施の形態を図面に基づき説明する。
図1に示すように、このマスク(1)は、装着者の口と鼻孔を覆うことができ、シート状布帛からなるマスク本体(2)と、ゴム弾性を備えた紐状の保持部材(3)と、このマスク本体(2)と装着者の顔面との間に配置されるフィルタ材(4)とを備える。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, this mask (1) can cover a wearer's mouth and nostril, and comprises a mask body (2) made of sheet-like fabric, and a string-like holding member (3 And a filter material (4) disposed between the mask body (2) and the face of the wearer.

上記のマスク本体(2)は、例えば平面状の不織布に襞が形成してあり、中央部を装着者の顔面から離隔する方向へ、即ち外側へ湾曲させることができ、装着者の顔面に沿った立体形状にすることができる。このマスク本体(2)の両側部には、それぞれ上記の保持部材(3)の両端が熱融着等で固定してある。この保持部材(3)はゴム弾性を備えており、これを装着者の両耳に掛けることで、上記のマスク本体(2)が引っ張られて装着者の顔面前方の所定位置に保持される。   The mask main body (2) has, for example, a flat non-woven fabric formed with wrinkles, and can be curved in a direction away from the wearer's face, that is, outward, along the face of the wearer. 3D shape can be obtained. On both sides of the mask body (2), both ends of the holding member (3) are fixed by heat sealing or the like. This holding member (3) is provided with rubber elasticity, and when this is put on both ears of the wearer, the mask body (2) is pulled and held at a predetermined position in front of the face of the wearer.

上記のフィルタ材(4)は、上記のマスク本体(2)とは別体に形成してあり、そのマスク本体(2)に固定されていない。しかし、装着時には上記の保持部材(3)によるマスク本体(2)の装着力により、装着者の顔面側へ押圧されて保持される。即ち、上記のマスク本体(2)は、このフィルタ材(4)を装着者の顔面側へ押圧する押圧部材(5)となっている。   The filter material (4) is formed separately from the mask body (2) and is not fixed to the mask body (2). However, at the time of wearing, the mask body (2) is pushed and held to the face side of the wearer by the wearing force of the mask body (2) by the holding member (3). That is, the mask body (2) is a pressing member (5) that presses the filter material (4) toward the face of the wearer.

図1と図2に示すように、上記のフィルタ材(4)は、装着者の顔面形状に沿った立体形状に形成してあり、中央部分(6)を外側(装着者の顔面から離隔する方向)へ湾曲させるとともに、周縁部分(7)の厚みを厚く形成してある。装着時は、その周縁部分(7)が装着者の口と鼻孔を取り囲む状態に配置され、上記の中央部分(6)と装着者の顔面との間に空間が形成される。そして上記の周縁部分(7)は、上記のマスク本体(2)の装着力で装着者の顔面側へ押圧されて、復元可能に厚さ方向へ圧縮変形する。   As shown in FIGS. 1 and 2, the filter material (4) is formed in a three-dimensional shape along the wearer's face shape, and the central portion (6) is outside (separated from the wearer's face). And the peripheral portion (7) is formed thick. At the time of wearing, the peripheral portion (7) is arranged so as to surround the mouth and nostril of the wearer, and a space is formed between the central portion (6) and the face of the wearer. The peripheral portion (7) is pressed toward the face of the wearer by the mounting force of the mask body (2), and is compressed and deformed in the thickness direction so as to be restored.

上記のフィルタ材(4)は、例えば、30重量%の綿と、55重量%のレギュラータイプのポリエステル繊維(例えば、太さ4.4dtex、長さ51mm)と、15重量%の低融点ポリエステル共重合体繊維(例えば、太さ1.7dtex、長さ51mm)とを混紡した不織布が用いてある。なお、上記の低融点ポリエステル共重合体繊維は、例えば融点が110℃である。この不織布は、例えば目付が200g/mであり、厚さは中央部分(6)が約5mmであり、周縁部分(7)が8mmである。この不織布は、上記の混紡比率で加重平均した比重が1.1g/cmであるので、前記の式1により算出した空隙率は、周縁部分で約97.7%となっており、中央部分(6)で約96.4%となっている。 The filter material (4) is made of, for example, 30% by weight of cotton, 55% by weight of a regular type polyester fiber (for example, 4.4 dtex in thickness and 51 mm in length) and 15% by weight of a low-melting polyester. A nonwoven fabric blended with polymer fibers (for example, a thickness of 1.7 dtex and a length of 51 mm) is used. The low melting point polyester copolymer fiber has a melting point of 110 ° C., for example. This nonwoven fabric has, for example, a basis weight of 200 g / m 2 , a thickness of about 5 mm in the central portion (6), and a peripheral portion (7) of 8 mm. Since this non-woven fabric has a weighted average specific gravity of 1.1 g / cm 3 at the above blend ratio, the porosity calculated by the above equation 1 is about 97.7% at the peripheral portion, and the central portion In (6), it is about 96.4%.

上記の不織布の両面には、伸縮性と通気性とを備えた保護層(8)が一体的に積層してある。この保護層(8)は、例えばポリエステル繊維などの合成繊維を、丸編みの天竺編で形成され、使用された編糸の太さは、例えば83dtexなどの細い糸が用いてある。このためこの保護層(8)は極めて薄く形成してあるが、後述の抗菌加工処理や成形加工処理などのハンドリングに必要な引張強度等が、この保護層(8)で確保されている。   A protective layer (8) having stretchability and breathability is integrally laminated on both surfaces of the nonwoven fabric. The protective layer (8) is made of synthetic fiber such as polyester fiber by circular knitting, and thin yarn such as 83 dtex is used as the thickness of the used knitting yarn. For this reason, the protective layer (8) is formed extremely thin, but the protective layer (8) has a tensile strength necessary for handling such as antibacterial processing and molding processing described later.

上記の不織布を構成する、セルロース系繊維である綿には、全体に銀の金属イオンを含有する抗菌剤が坦持させてある。この抗菌剤は、例えば次の抗菌処理加工により坦持させることができる。
最初に、上記の不織布を、濃度が3000ユニット/mlのペクチン分解酵素と0.1重量%の界面活性剤とを含む水溶液に、室温で2時間浸漬したのち、水洗して乾燥させる。次いで、10mM濃度の銀イオン水溶液に1時間浸漬し、これを取り出して水溶液を絞りとったのち、洗浄して乾燥して、抗菌処理加工を終了する。なお、上記の銀イオン水溶液は、例えば三菱重工産業機器株式会社製の銀イオン水生成装置により製造することができる。
Cotton, which is a cellulosic fiber that constitutes the above-mentioned nonwoven fabric, carries an antibacterial agent containing silver metal ions as a whole. This antibacterial agent can be carried, for example, by the following antibacterial treatment.
First, the non-woven fabric is immersed in an aqueous solution containing a pectin-degrading enzyme having a concentration of 3000 units / ml and a surfactant of 0.1% by weight at room temperature for 2 hours, washed with water and dried. Next, it is immersed in a 10 mM aqueous silver ion solution for 1 hour, taken out and squeezed, and then washed and dried to finish the antibacterial treatment. In addition, said silver ion aqueous solution can be manufactured with the silver ion water production | generation apparatus by Mitsubishi Heavy Industries Industrial Equipment Co., Ltd., for example.

上記の抗菌加工処理を終えたフィルタ材(4)は、所定形状にカットされたのち、金型内にセットして、130℃に加熱することで、上記の所定の形状に成形される。このとき、フィルタ材(4)の中央部分(6)は外側へ湾曲されるとともに圧縮されて、厚さが5mmとなり、これに対し周縁部分(7)は、厚さが8mmに維持される。   The filter material (4) having been subjected to the antibacterial processing is cut into a predetermined shape, and then set in a mold and heated to 130 ° C. to be molded into the predetermined shape. At this time, the central portion (6) of the filter material (4) is curved outward and compressed to a thickness of 5 mm, while the peripheral portion (7) is maintained at a thickness of 8 mm.

上記の第1実施形態では、フィルタ材(4)をマスク本体(2)とは別体に形成した。しかし本発明では、このフィルタ材をマスク本体に固定してもよい。
即ち図3に示す第2実施形態では、フィルタ材(4)の外側表面の周縁部分に沿って接着剤(9)が付設してあり、この接着剤(9)を介してフィルタ材(4)がマスク本体(2)に固定してある。
In the first embodiment, the filter material (4) is formed separately from the mask body (2). However, in the present invention, this filter material may be fixed to the mask body.
That is, in 2nd Embodiment shown in FIG. 3, the adhesive agent (9) is attached along the peripheral part of the outer surface of filter material (4), and filter material (4) is passed through this adhesive agent (9). Is fixed to the mask body (2).

この第2実施形態では、マスク本体(2)が所定形状に形成した2片の一端部を互いに接合した構造となっており、この2片を左右に開くことで、このマスク本体(2)が立体形状となる。各片の接合端部とは反対側の端部に、保持部材(3)が延設してある。   In the second embodiment, the mask body (2) has a structure in which one end of two pieces formed in a predetermined shape are joined to each other. By opening the two pieces to the left and right, the mask body (2) It becomes a three-dimensional shape. A holding member (3) extends from the end opposite to the joining end of each piece.

また上記のフィルタ材(4)は、上記の第1実施形態と同様、周縁部分(7)が厚く形成してあるが、第1実施形態と異なり、装着者の鼻梁の両側部に対応する部位(7a)は、他の周縁部分(7)よりも特に厚く形成してある。これにより、装着時に装着者の鼻梁の両側部と確実に隙間なく密着できるようにしてある。その他の構成は上記の第1実施形態と同様であり、同様に作用するので説明を省略する。   The filter material (4) has a thick peripheral portion (7) as in the first embodiment, but unlike the first embodiment, portions corresponding to both sides of the wearer's nasal bridge. (7a) is formed to be particularly thicker than the other peripheral portion (7). This ensures that it can be in close contact with both sides of the wearer's nasal bridge without any gaps. The other configuration is the same as that of the first embodiment described above, and functions in the same manner, so that the description is omitted.

上記の実施形態で説明したマスク用フィルタ材とこれを用いたマスクは、本発明の技術的思想を具体化するために例示したものであり、各部の形状や寸法、材質、構造、加工処理方法などをこの実施形態のものに限定するものではなく、本発明の特許請求の範囲内において種々の変更を加え得るものである。   The mask filter material and the mask using the mask material described in the above embodiment are illustrated to embody the technical idea of the present invention, and the shape, dimensions, material, structure, and processing method of each part. Are not limited to those of this embodiment, and various modifications can be made within the scope of the claims of the present invention.

例えば、上記のフィルタ材等に用いた繊維の種類や、太さ、繊維長などは、単なる例示であり、本発明では他の種類や寸法の繊維を用いてもよいことは言うまでもない。
また上記の実施形態では、マスク本体に不織布を用いたが、本発明のマスク本体や押圧部材は、フィルタ材を装着者の顔面側へ押圧できるものであればよく、例えば織布であってもよく、目の粗い網状体であってもよい。従って、上記の保護層をこのマスク本体や押圧部材として用いることも可能である。
For example, the types, thicknesses, fiber lengths, and the like of the fibers used in the filter material are merely examples, and it goes without saying that fibers of other types and dimensions may be used in the present invention.
In the above embodiment, a non-woven fabric is used for the mask main body. However, the mask main body and the pressing member of the present invention are not limited as long as they can press the filter material toward the face of the wearer. It may be a mesh with a coarse mesh. Therefore, it is possible to use the protective layer as the mask body or the pressing member.

また上記の各実施形態では、フィルタ材(4)の両面にポリエステル繊維製の保護層(8)を形成したが、本発明ではフィルタ材の片面にのみこの保護層を形成したものであってもよく、或いはこれを省略したものであってもよい。この保護層は伸縮性と通気性があればよく、ポリエステル繊維以外の繊維を用いてもよく、他の編み方等であってもよい。   In each of the above embodiments, the protective layer (8) made of polyester fiber is formed on both sides of the filter material (4). However, in the present invention, this protective layer may be formed only on one side of the filter material. Or it may be omitted. The protective layer only needs to be stretchable and breathable, and may use fibers other than polyester fibers, or other knitting methods.

上記の各実施形態では、フィルタ材の周縁部分を厚く形成し、中央部分をこれよりも薄く形成したが、本発明のフィルタ材は全体が均一な厚さであってもよい。
また上記の第1実施形態では、このフィルタ材に抗菌剤を坦持させた場合について説明した。しかし本発明では、この抗菌剤に代えて殺菌剤を坦持させてもよく、或いはこれらを坦持させないものであってもよい。また上記の第1実施形態では抗菌剤等をフィルタ材の全体に坦持させたので、抗菌処理加工を簡略にできたが、本発明では呼・吸気が通過する部位に坦持させてあればよく、例えば周縁部分のみに抗菌剤等を坦持させてもよい。
In each of the above embodiments, the peripheral portion of the filter material is formed thick and the central portion is formed thinner than this, but the filter material of the present invention may have a uniform thickness as a whole.
Moreover, said 1st Embodiment demonstrated the case where an antibacterial agent was made to carry on this filter material. However, in the present invention, a bactericidal agent may be carried instead of the antibacterial agent or may not be carried. In the first embodiment, the antibacterial agent or the like is carried on the entire filter material, so that the antibacterial processing can be simplified. However, in the present invention, the antibacterial agent can be carried on the part through which the call / intake passes. For example, an antibacterial agent or the like may be carried only on the peripheral portion.

上記の第1実施形態では、成形加工処理前の不織布に抗菌加工処理を施した。しかし本発明では、成形加工処理後に抗菌加工処理等を施してもよく、或いは、不織布にする前の繊維の状態で抗菌加工処理等を施してもよい。   In said 1st Embodiment, the antibacterial processing was given to the nonwoven fabric before a shaping | molding process. However, in the present invention, the antibacterial processing or the like may be performed after the molding processing, or the antibacterial processing or the like may be performed in a fiber state before forming the nonwoven fabric.

また上記の各実施形態では上記の保持部材を、いずれも装着者の耳に掛けることでマスク本体を装着するように構成した。しかし本発明ではこの保持部材を、装着者の頭部の後方へ回すことで、マスク本体を装着するものであってもよい。
また上記の各実施形態ではフィルタ材に不織布を用いたが、本発明では連続気泡の発泡体を用いてもよい。さらに上記の第1実施形態では、上記の不織布に綿を混紡したが、レーヨンや他の合成繊維等の不織布を用いてもよいことは、いうまでもない。
In each of the above-described embodiments, the mask main body is mounted by hanging the holding members on the wearer's ears. However, in the present invention, the mask body may be mounted by turning the holding member to the back of the wearer's head.
In each of the above embodiments, a nonwoven fabric is used as the filter material. However, in the present invention, an open-cell foam may be used. Furthermore, in said 1st Embodiment, although cotton was mixed with said nonwoven fabric, it cannot be overemphasized that nonwoven fabrics, such as rayon and another synthetic fiber, may be used.

本発明のマスク用フィルタ材とこれを用いたマスクは、着脱が容易でありながら、口や鼻孔の周囲を隙間なく覆うことができ、呼・吸気からウイルスや花粉、塵埃などの微細な異物を効率的に除去できるので、ウイルスや細菌などから身を守る衛生マスクとして特に好適であるが、粉塵処理など、塵埃の多い場所で作業する際に装着する防塵マスクとしても好適である。   The filter material for a mask of the present invention and a mask using the mask material can cover the mouth and nostrils without gaps while being easy to attach and detach, and can collect fine foreign matters such as viruses, pollen and dust from the call and inhalation. Since it can be efficiently removed, it is particularly suitable as a sanitary mask that protects itself from viruses and bacteria, but is also suitable as a dust mask to be worn when working in dusty places such as dust treatment.
