本考案に係る不織布製マスクの第５の特徴は、上記第１、第２、第４および第４の何れかの特徴に加えて、生地５１（５２）が複数枚の不織布を重ねて構成されている点にある。 The fifth feature of the non-woven fabric mask according to the present invention is that, in addition to any of the first, second, fourth and fourth features, the fabric 51 (52) is formed by stacking a plurality of non-woven fabrics. There is in point.

本考案（請求項１）において、不織布６１に使用の繊維５６は、単繊維繊度が５ｄｔｅｘ以下で細く、繊維長が１０〜７０ｍ／ｍの短繊維であり、紡績カードによってラップ（繊維集積シート）に調製されて不織布を構成しているので、その不織布は、目付けが２５〜５５ｇ／ｍ² であっても嵩高で繊維間の隙間も細かく、塵埃が透過し難く、低目付けであることからして通気性に富み、フィルターとしての防塵機能に富む。 In the present invention (Claim 1), the fibers 56 used in the nonwoven fabric 61 are short fibers having a single fiber fineness of 5 dtex or less and a fiber length of 10 to 70 m / m, and are wrapped by a spinning card (fiber integrated sheet). The non-woven fabric is made of a non-woven fabric, so that the non-woven fabric is bulky and has a fine gap between fibers even when the basis weight is 25 to 55 g / m ² , and it is difficult for dust to permeate and has a low basis weight. Rich in air permeability and dustproof function as a filter.

その不織布は、目付けが２５〜５５ｇ／ｍ² で軽く、通気性に富むので、本考案のマスクは、格別着用しているとの感触を与えず、着用して息苦しく感じられることもない。
又、そのように生地５１・５２の目付けが２５〜５５ｇ／ｍ² であれば、乾燥し易く、吐息が結露し難く、結露による蒸れやベトツキ、結露による汚染も少なく、不快感を与えず、マスクの洗浄・乾燥が容易で清潔に保たれる。 Since the non-woven fabric is light in weight of 25 to 55 g / m ² and rich in air permeability, the mask of the present invention does not give a feeling that it is particularly worn and does not feel stuffy when worn.
In addition, if the fabric weight of the dough 51, 52 is 25 to 55 g / m ² , it is easy to dry, the sighs are not easily condensed, there is little stuffiness or stickiness due to condensation, no contamination due to condensation, and no discomfort. Mask cleaning and drying is easy and clean.

特に、短繊維に成る低目付けの不織布は、伸び易く形状が不安定であるが、本考案では、飛び飛びに窪んだ窪み５３において繊維間が融着しているので形状が安定し、窪み５３と窪み５３の間の未接合部分５９では繊維間がフリーになっていて伸縮し、顔肌の起伏に馴染み易い。
そして、鼻先縁の融着代５７や閉じ紐５５の接合箇所５０では、繊維間が融着して固い溶融皮膜を形成しているとしても、それらの露出面は生地の同じ片面であり、その露出面を外側に向ければ、その固い溶融皮膜が不快感を与えることがなく、又、窪み５３における溶融皮膜５４も窪んだ谷底にあって直接顔肌に触れることがなく不快感を与えない。
却って、細かい間隔（ｘ，ｙ）で飛び飛びに窪み５３を設けるときは、生地５１（５２）と顔肌との接触面積が少なくなるので、着用してマスクから受ける蒸れやベトツキ感も解消される。
目付けが２５〜５５ｇ／ｍ² の不織布は、閉じ紐５５よりも弱く、その閉じ紐５５との接合箇所５０は、閉じ紐５５よりも更に脆弱なので、マスクの廃棄時に閉じ紐５５を強く引っ張れば、その接合箇所５０が破れて生地５１・５２と閉じ紐５５とに容易に分離するので、生地５１・５２と閉じ紐５５の材質が異なっていても、それらを分別して回収し易くなり、それらの資材のリサイクルが容易になる。 In particular, a low-weight nonwoven fabric made of short fibers is easy to stretch and has an unstable shape. However, in the present invention, the fibers are fused in the hollows 53 that are hollowed out so that the shape is stable. In the unjoined part 59 between the dents 53, the fiber is free and expands and contracts, so that it is easy to become familiar with the undulations of the facial skin.
And, in the fusion margin 57 of the nose tip edge and the joint portion 50 of the closing string 55, even if the fibers are fused to form a hard melt film, those exposed surfaces are the same one side of the fabric, If the exposed surface is directed outward, the hard molten film does not give an unpleasant feeling, and the molten film 54 in the depression 53 is also in the recessed valley bottom and does not touch the face skin directly and does not give an unpleasant feeling.
On the other hand, when the dents 53 are provided so as to fly away at a fine interval (x, y), the contact area between the fabric 51 (52) and the face skin is reduced, so that the feeling of stuffiness and stickiness received from the mask is also eliminated. .
A non-woven fabric having a basis weight of 25 to 55 g / m ² is weaker than the closing string 55, and the joint 50 with the closing string 55 is more fragile than the closing string 55. Therefore, if the closing string 55 is pulled strongly when the mask is discarded. Since the joint portion 50 is broken and easily separated into the fabrics 51 and 52 and the closing string 55, even if the materials of the fabrics 51 and 52 and the closing string 55 are different, they can be easily separated and collected. Recycling of materials becomes easy.

本考案（請求項２）では、鼻先縁４３が、鼻先縁４３と頬側縁４２とのコーナーＣと、鼻先縁４３と顎側縁４４とのコーナーＤを結ぶ直線（ＣＤ）よりも生地５１（５２）の外側に膨出し、マスクの鼻先部分が袋状になっており、着用時に、その袋状部分に鼻先が嵌まり込む恰好になり、鼻先が生地に直接触れ難い。
一方、頬側縁４２が、耳側縁４１と頬側縁４２とのコーナーＢと、鼻先縁４３と頬側縁４２とのコーナーＣを結ぶ直線（ＢＣ）よりも生地５１（５２）の内側に窪んでおり、又、顎側縁４４も、鼻先縁４３と顎側縁４４とのコーナーＤと、耳側縁４１と顎側縁４４とのコーナーＡを結ぶ直線（ＤＡ）よりも生地５１（５２）の内側に窪んでおり、頬側縁４２と顎側縁４４が頬肌や顎肌の起伏に馴染んで密着し易く、その密着する頬側縁４２や顎側縁４４によって相対的に鼻先縁４３が押し上げられて鼻先から離れ易くなり、マスクの鼻先部分と鼻先の間に隙間が出来易く、着用時に息苦しさを与えず、鼻先部分と鼻先の間に隙間が断熱層を構成し、又、その隙間に籠もる吐息によって保温感を受けることになる。 In the present invention (Claim 2), the nose tip edge 43 has a cloth 51 rather than a straight line (CD) connecting the corner C of the nose tip edge 43 and the cheek side edge 42 and the corner D of the nose tip edge 43 and the jaw side edge 44. It bulges outside (52), and the nose tip portion of the mask is in a bag shape. When worn, the nose tip fits into the bag-like portion and the nose tip is difficult to touch the fabric directly.
On the other hand, the cheek side edge 42 is inside the fabric 51 (52) rather than the straight line (BC) connecting the corner B of the ear side edge 41 and the cheek side edge 42 and the corner C of the nose tip edge 43 and the cheek side edge 42. Further, the chin side edge 44 is also a fabric 51 than a straight line (DA) connecting the corner D of the nose tip edge 43 and the chin side edge 44 and the corner A of the ear side edge 41 and the chin side edge 44. (52), and the cheek side edge 42 and the chin side edge 44 are easy to adhere to and adhere to the undulations of the cheek skin and the chin skin, and the cheek side edge 42 and the chin side edge 44 are relatively close to each other. The nose tip edge 43 is pushed up and easily separated from the nose tip, a gap is easily formed between the nose tip portion and the nose tip of the mask, does not give breathiness when worn, and the gap constitutes a heat insulating layer between the nose tip portion and the nose tip, Moreover, a warm feeling is received by the sigh which stagnates in the gap.

特に、頬側縁４２の生地５１（５２）の内側に窪む窪み量Ｓを、顎側縁４４の生地５１（５２）の内側に窪む窪み量Ｕよりも大きくすると、マスクの鼻先部分がこめかみまで膨出し、鼻先縁４３と頬側縁４２とのコーナー部分（Ｃ）が鼻と頬の間の窪みに密着し、にこめかみに到る鼻先全体が、キャップを被せたかの如く、鼻先縁４３と、鼻先縁４３と頬側縁４２とのコーナーＣと鼻先縁４３と顎側縁４４とのコーナーＤを結ぶ直線（ＣＤ）に囲まれる鼻先縁の袋状部分に包まれる一方、頬側縁４２や顎側縁４４が頬肌や顎肌の起伏に馴染んで密着し易くなる。
その結果、頬側縁４２と頬肌の間、および、顎側縁４４と顎肌の間からの空気の出入りが抑えられ、生地５１（５２）を透過する空気の透過量が相対的に増えて、マスクのフィルター機能が高まる。 In particular, if the amount of depression S recessed inside the fabric 51 (52) of the cheek side edge 42 is larger than the amount of depression U recessed inside the fabric 51 (52) of the jaw side edge 44, the nose tip portion of the mask The corner of the nose tip 43 and the cheek side edge 42 is in close contact with the dent between the nose and the cheek, and the nose tip 43 as if the entire nose leading to the temple is covered with a cap.
