Description

マスクmask
　本発明は、マスクに関する。 The present invention relates to a mask.
　従来、鼻及び口を覆うマスクの素材としては、不織布の他、ガーゼのような織布又は編地等の生地が用いられている。不織布は密度が高いため、フィルター機能に優れるが、肌触りは柔らかい生地の方が良好である（例えば特許文献１参照）。 Conventionally, as the material of the mask covering the nose and mouth, in addition to the non-woven fabric, a woven fabric such as gauze or a fabric such as a knitted fabric has been used. Since the non-woven fabric has a high density, it has an excellent filter function, but a soft fabric is better to the touch (see, for example, Patent Document 1).
実用新案登録第３２２１０９５号Utility model registration No. 3221095
　生地を用いたマスクのなかには、複数枚の生地が重ねられ、その端部が縫い合わされたマスクがある。通常は、ほつれを防ぐために生地の端が内側に折り込まれて縫い合わされる。 Among the masks using fabrics, there are masks in which multiple fabrics are layered and the ends are sewn together. Usually, the edges of the fabric are folded inward and sewn together to prevent fraying.
　そのため、マスクの端部では重ねられる生地の枚数が多くなり、厚みが増える。端部が厚すぎると、鼻の形や顔の表面にマスクがフィットせず、着用者が違和感を覚えることがある。 Therefore, the number of layers of fabric at the end of the mask increases, and the thickness increases. If the edges are too thick, the mask will not fit the shape of the nose or the surface of the face, and the wearer may feel uncomfortable.
　本発明は、フィット性に優れたマスクの提供を目的とする。 An object of the present invention is to provide a mask having excellent fit.
　本発明の一態様は、表面生地（１１）と裏面生地（１２）とが縫着されたマスク（１０）である。表面生地（１１）及び裏面生地（１２）は、上端部（１ａ）が左右に連続し、上端部（１ａ）よりも下方が左右に分離している形状を有する。 One aspect of the present invention is a mask (10) in which a front surface fabric (11) and a back surface fabric (12) are sewn together. The front surface fabric (11) and the back surface fabric (12) have a shape in which the upper end portion (1a) is continuous to the left and right and the lower end portion (1a) is separated to the left and right.
　本発明によれば、フィット性に優れたマスクを提供することができる。 According to the present invention, it is possible to provide a mask having excellent fit.

　編地の編組織としては、フライス、スムース、天竺、ベア天竺、鹿の子、片袋、ポンチローマ、ミラノリブ、パール編等が例示される。着用のしやすさの観点からは、伸度及び弾力性が高い緯編地が好ましい。マスク１０のフィット性を高める観点からは、ベア天竺が好ましい。 Examples of the knitting structure of the knitted fabric include milling, smooth, tenjiku, bear tenjiku, Kanoko, one bag, punch roma, Milan rib, and pearl knitting. From the viewpoint of ease of wearing, a weft knitted fabric having high elongation and elasticity is preferable. From the viewpoint of improving the fit of the mask 10, a bare cloth is preferable.
　表面生地１１及び裏面生地１２は、通気性に優れた編地であることが好ましい。マスク１０内部に呼気がこもりにくく、着用時の不快感を減らすことができる。通気性は、使用する繊維、繊維の細さ、又は編組織等によって高めることができる。 The front surface fabric 11 and the back surface fabric 12 are preferably knitted fabrics having excellent breathability. Exhalation is less likely to be trapped inside the mask 10, and discomfort during wearing can be reduced. Breathability can be enhanced by the fibers used, the fineness of the fibers, the knitting structure, and the like.
　例えば、キュプラ等のセルロース繊維の割合を減らし、ポリエステル等の合成繊維の割合を増やした編地は通気性に優れ、表面生地１１及び裏面生地１２の編地として好ましく使用することができる。 For example, a knitted fabric having a reduced proportion of cellulose fibers such as cupra and an increased proportion of synthetic fibers such as polyester has excellent breathability and can be preferably used as a knitted fabric for the front surface fabric 11 and the back surface fabric 12.
　通気性に優れた編組織としては、例えばハニカムメッシュ、ダブルフェイス、鹿の子等が挙げられる。 Examples of the knitting structure having excellent breathability include honeycomb mesh, double face, and Kanoko.
　着用者の顔に接する裏面生地１２は、接触冷感を有してもよい。接触冷感は、上述したポリアミド、ポリオレフィン、又はポリウレタン等の合成繊維を用いることにより高めることができる。 The back surface fabric 12 in contact with the wearer's face may have a cool contact feeling. The cool contact feeling can be enhanced by using the above-mentioned synthetic fibers such as polyamide, polyolefin, and polyurethane.
　接触冷感を有し、かつ肌触りも良好な編地としては、例えば特許第６１６６２９９５号に開示された編地を使用できる。これは、単糸繊度が０．８～４ｄｔｅｘのセルロース繊維を２０質量％以上使用した編地であって、編地の充填密度が０．２６～０．５ｇ／ｍ３である。この編地は、吸湿性及び消臭機能にも優れる。 As a knitted fabric having a cool contact feeling and a good touch, for example, the knitted fabric disclosed in Japanese Patent No. 616629295 can be used. This is a knitted fabric using 20% by mass or more of cellulose fibers having a single yarn fineness of 0.8 to 4 dtex, and the filling density of the knitted fabric is 0.26 to 0.5 g / m 3 . This knitted fabric is also excellent in hygroscopicity and deodorant function.
　特許第６３７１５９３号に開示された編地も好適に使用できる。この編地は、セルロース繊維と合成繊維とが混繊された複合糸条と、合成繊維の糸条とが交編されたベア天竺の編地であって、編地におけるセルロース繊維の割合が２０％以上である。 The knitted fabric disclosed in Japanese Patent No. 6371593 can also be preferably used.

　フィルター１３は、表面生地１１又は裏面生地１２よりも密度が高く、花粉等の異物の遮蔽率を高めることができる。 The filter 13 has a higher density than the front surface fabric 11 or the back surface fabric 12, and can increase the shielding rate of foreign substances such as pollen.
　本実施形態のフィルター１３は単層構造であるが、フィルター１３は多層構造であってもよい。複数のフィルター１３は、着用者に近いほどろ過効率が高くなるように配置され得る。 The filter 13 of the present embodiment has a single-layer structure, but the filter 13 may have a multi-layer structure. The plurality of filters 13 may be arranged so that the closer to the wearer, the higher the filtration efficiency.
　衛生性の観点からは、フィルター１３のバクテリア（細菌）ろ過効率（ＢＦＥ：Bacterial Filtration Efficiency）が高いことが好ましい。ＢＦＥは、ＡＳＴＭ　Ｆ２１０１に準拠して測定される。 From the viewpoint of hygiene, it is preferable that the filter 13 has a high bacterial filtration efficiency (BFE: Bacterial Filtration Efficiency). BFE is measured according to ASTM F2101.
　花粉拡散を抑える観点からは、フィルター１３の花粉ろ過効率が高いことが好ましい。飛沫拡散を抑える観点からは、微粒子ろ過効率（ＰＦＥ：Particle Filtration Efficiency）が高いことが好ましい。ＰＦＥは、ＡＳＴＭ　Ｆ２２９９に準拠して測定される。 From the viewpoint of suppressing pollen diffusion, it is preferable that the pollen filtration efficiency of the filter 13 is high. From the viewpoint of suppressing the diffusion of droplets, it is preferable that the particle filtration efficiency (PFE: Particle Filtration Efficiency) is high. PFE is measured according to ASTM F2299.
　フィルター１３の例としては、ｎｍ単位の極細繊維、例えばポリテトラフルオロエチレン（ＰＴＦＥ）のナノファイバーを用いた不織布シート、ポリエチレン樹脂、ポリプロピレン樹脂等の合成繊維の不織布シート等が挙げられる。 Examples of the filter 13 include a non-woven fabric sheet using nanofibers of nm unit, for example, polytetrafluoroethylene (PTFE) nanofibers, a non-woven fabric sheet of synthetic fibers such as polyethylene resin and polypropylene resin, and the like.
（耳掛け部）
　耳掛け部２は、本体部１の左右両端に設けられるループ状のテープ部材である。例えば、テープ部材は伸縮性を有するゴムひも等である。テープ部材の一端が本体部１の左右両端の上側に、他端が下側に取り付けられて、ループが形成される。 (Ear hook)
The ear hook portion 2 is a loop-shaped tape member provided at both left and right ends of the main body portion 1. For example, the tape member is an elastic rubber string or the like. One end of the tape member is attached to the upper side of the left and right ends of the main body 1, and the other end is attached to the lower side to form a loop.
（マスクの製造方法）
　マスク１０は、本体部１を形成し、本体部１に耳掛け部２を設けることにより、形成され得る。 (Mask manufacturing method)
The mask 10 can be formed by forming the main body 1 and providing the ear hook 2 on the main body 1.
　本体部１は、表面生地１１、フィルター１３及び裏面生地１２を重ねて縫着することにより、形成される。縫着前の表面生地１１、裏面生地１２及びフィルター１３は、前中心Ｍにおいて左右対称の形状を有する。 The main body portion 1 is formed by overlapping and sewing the front surface fabric 11, the filter 13, and the back surface fabric 12. The front surface fabric 11, the back surface fabric 12, and the filter 13 before sewing have a symmetrical shape at the front center M.
　図３は、表面生地１１の展開図である。裏面生地１２及びフィルター１３も、表面生地１１と同じ形状を有する。 FIG. 3 is a developed view of the surface fabric 11. The back surface fabric 12 and the filter 13 also have the same shape as the front surface fabric 11.
　表面生地１１は、上端部１ａが前中心Ｍにおいて左右に連続し、上端部１ａより下方が前中心Ｍにおいて左右に分離されている形状を有する。 The surface fabric 11 has a shape in which the upper end portion 1a is continuous to the left and right at the front center M, and the lower end portion 1a is separated to the left and right at the front center M.
　左右に分離された生地部分ｗ１及びｗ２の離間距離ｄは、下方に向かうほど長い。そのため、生地部分ｗ１及びｗ２の前中心Ｍ側の側端１ｂは、湾曲する形状を有する。 The separation distance d between the fabric portions w1 and w2 separated to the left and right is longer toward the bottom. Therefore, the side ends 1b of the fabric portions w1 and w2 on the front center M side have a curved shape.
　まずフィルター１３が表面生地１１に重ねられる。フィルター１３が重ねられた状態で、表面生地１１の生地部分ｗ１の側端１ｂと生地部分ｗ２の側端１ｂとが、互いに対面するように重ねられる。このとき、フィルター１３の生地部分ｗ１及び生地部分ｗ２は、重ねられた表面生地１１の両側に位置する。 First, the filter 13 is layered on the surface fabric 11. With the filters 13 stacked, the side end 1b of the dough portion w1 of the surface fabric 11 and the side end 1b of the dough portion w2 are overlapped so as to face each other. At this time, the fabric portion w1 and the fabric portion w2 of the filter 13 are located on both sides of the overlapped surface fabric 11.
　次いで、重ねられた表面生地１１の側端１ｂ同士が、フィルター１３とともに縫着される。糸のほつれを減らすため、側端の縫着方法としては、かがり縫い、ジグザグ縫い等が使用できる。 Next, the side edges 1b of the stacked surface fabrics 11 are sewn together with the filter 13. In order to reduce the fraying of the thread, overlock stitching, zigzag stitching and the like can be used as the sewing method of the side end.
　側端１ｂの縫着線は、マスク１０の着用時に前中心Ｍに位置する。側端１ｂは湾曲するため、縫着によって、前中心Ｍに沿って前側に膨出する立体形状が形成される。 The sewing line of the side end 1b is located at the front center M when the mask 10 is worn. Since the side end 1b is curved, a three-dimensional shape that bulges forward along the front center M is formed by sewing.
　側端１ｂの縫着方法は、伸ばし縫いであることが好ましい。伸ばし縫いとは、ミシンの差動送り機構によって生地の送り量を調整することにより、生地を伸ばしながら縫着する方法をいう。 The sewing method of the side end 1b is preferably stretch stitching. Stretch stitching is a method of sewing while stretching the fabric by adjusting the feed amount of the fabric by the differential feed mechanism of the sewing machine.
　伸ばし縫いにより、縫製による編地の縮みを抑え、張りのある自然な曲線状の前中心Ｍを形成できる。また前中心Ｍの周辺の生地に生じる皺や陥没を減らしてデザイン性を高めることができる。 By stretch stitching, shrinkage of the knitted fabric due to sewing can be suppressed, and a natural curved front center M with tension can be formed. In addition, wrinkles and depressions that occur in the fabric around the front center M can be reduced to improve the design.
　編地の伸び過ぎを避ける観点から、側端１ｂの縫い代にウーリースピンテープ等の伸び止めテープが縫着されてもよい。 From the viewpoint of avoiding overstretching of the knitted fabric, a stretch-preventing tape such as wooly spin tape may be sewn to the seam allowance of the side end 1b.
　裏面生地１２においても、生地部分ｗ１の側端１ｂと生地部分ｗ２の側端１ｂとが縫着される。これにより、表面生地１１と同じ立体形状が形成される。立体形状が形成された表面生地１１と裏面生地１２とは、前中心Ｍにおいて縫い代を有しない面が互いに対面するように重ねられる。 Also in the back surface fabric 12, the side end 1b of the fabric portion w1 and the side end 1b of the fabric portion w2 are sewn. As a result, the same three-dimensional shape as the surface fabric 11 is formed. The front surface fabric 11 and the back surface fabric 12 on which the three-dimensional shape is formed are overlapped so that the surfaces having no seam allowance face each other at the front center M.
　このとき、表面生地１１の縫い代は前中心Ｍにおいて左右のいずれか一方側に倒される。裏面生地１２の縫い代は、前中心Ｍにおいて表面生地１１の縫い代とは逆方向に倒される。互いの縫い代が重ならないため、前中心Ｍにおける厚みを抑えることができる。 At this time, the seam allowance of the surface fabric 11 is tilted to either the left or right side at the front center M. The seam allowance of the back surface fabric 12 is tilted in the direction opposite to the seam allowance of the front surface fabric 11 at the front center M. Since the seam allowances do not overlap each other, the thickness at the front center M can be suppressed.
　次いで、表面生地１１上にその上端に沿って伸縮テープ１４が配置される。表面生地１１は、伸縮テープ１４とともに上端及び下端において裏面生地１２と縫着される。糸のほつれを減らすため、上端及び下端の縫着方法としては、かがり縫い、ジグザグ縫い等が使用できる。 Next, the elastic tape 14 is placed on the surface fabric 11 along the upper end thereof. The front surface fabric 11 is sewn with the back surface fabric 12 at the upper and lower ends together with the elastic tape 14. In order to reduce the fraying of the thread, overlock stitching, zigzag stitching and the like can be used as the sewing method of the upper end and the lower end.
　上端及び下端が縫着されると、左右が開口する筒状の本体部１が得られる。この筒状の本体部１は裏返されて、前中心Ｍの縫い代が本体部１の内側に位置する。 When the upper end and the lower end are sewn, a cylindrical main body portion 1 having left and right openings is obtained. The tubular main body 1 is turned inside out, and the seam allowance of the front center M is located inside the main body 1.
　本体部１の左右の端部は、内側に折り返される。これにより、端部を縫着したときに縫い代を内側に位置させることができる。表面生地１１の折り返し部分と裏面生地１３の折り返し部分とは対面するように重ねられる。各折り返し部分の間には、耳掛け部２のテープ部材が配置される。 The left and right ends of the main body 1 are folded inward. As a result, the seam allowance can be positioned inward when the end portion is sewn. The folded portion of the front surface fabric 11 and the folded portion of the back surface fabric 13 are overlapped so as to face each other. A tape member of the ear hook 2 is arranged between the folded portions.
　次いで、本体部１の上下左右の端部が縫着され、縫着線３が設けられる。例えば縫着線３は、端から２ｍｍ等の一定距離離れた位置に設けられる。この縫着線３により、表面生地１１と裏面生地１２とが縫着される。またテープ部材が本体部１に縫着され、耳掛け部２が形成される。 Next, the upper, lower, left, and right ends of the main body 1 are sewn, and the sewing line 3 is provided. For example, the sewing line 3 is provided at a position separated from the end by a certain distance such as 2 mm. The front surface fabric 11 and the back surface fabric 12 are sewn by the sewing line 3. Further, the tape member is sewn to the main body portion 1 to form the ear hook portion 2.
　なお前中心Ｍに沿って縫着線が設けられてもよい。縫着線により、表面生地１１と裏面生地１２とが前中心Ｍにおいて接続されるため、使用中における表面生地１１と裏面生地１２とのずれを防ぐことができる。洗濯によるマスク１０の型崩れも防ぐことができる。 A sewing line may be provided along the front center M. Since the front surface fabric 11 and the back surface fabric 12 are connected at the front center M by the sewing line, it is possible to prevent the front surface fabric 11 and the back surface fabric 12 from slipping during use. It is also possible to prevent the mask 10 from losing its shape due to washing.
　図４は、Ａ－Ａ線における断面図である。Ａ－Ａ線は、本体部１の上端部１ａを前中心Ｍにおいて切断する。図５は、Ｂ－Ｂ線における断面図である。Ｂ－Ｂ線は、本体部１の上端部１ａより下方を前中心Ｍにおいて前中心Ｍに直交する方向に切断する。 FIG. 4 is a cross-sectional view taken along the line AA. The AA line cuts the upper end portion 1a of the main body portion 1 at the front center M. FIG. 5 is a cross-sectional view taken along the line BB. The BB line is cut below the upper end portion 1a of the main body portion 1 in the direction orthogonal to the front center M at the front center M.
　表面生地１１の上端部１ａと裏面生地１２の上端部１ａとは、互いの折り返された部分が対面するように重ねられ、縫着されている。フィルター１３は表面生地１１とともに折り返されるので、伸縮テープ１４を除いて上端部１ａにおいて重ねられる生地の枚数は、少なくとも６枚である。 The upper end portion 1a of the front surface fabric 11 and the upper end portion 1a of the back surface fabric 12 are overlapped and sewn so that the folded portions face each other. Since the filter 13 is folded back together with the surface fabric 11, the number of fabrics stacked at the upper end portion 1a except for the elastic tape 14 is at least six.
　一方、上端部１ａより下方においては、表面生地１１とフィルター１３とが２枚ずつ重ねられた縫い代が右側に倒される。この縫い代は裏面生地１２と重ねられる。よって、前中心Ｍの左側においては合計７枚の生地が重ねられる。 On the other hand, below the upper end 1a, the seam allowance in which the surface fabric 11 and the filter 13 are stacked two by two is tilted to the right. This seam allowance is overlapped with the back surface fabric 12. Therefore, a total of seven fabrics are stacked on the left side of the front center M.
　また２枚の裏面生地１２が重ねられた縫い代は左側に倒されている。この縫い代は表面生地１１とフィルター１３と重ねられる。よって、右側においては合計５枚の生地が重ねられる。 Also, the seam allowance on which the two back fabrics 12 are stacked is tilted to the left. This seam allowance is overlapped with the surface fabric 11 and the filter 13. Therefore, on the right side, a total of 5 pieces of dough are stacked.
　上端部１ａが前中心Ｍにおいて左右に連続しておらず、上端部１ａより下方の領域と同様に分離されている場合、折り返しにより、上端部１ａでは上端部１ａより下方の領域に比べて２倍の枚数の生地が重ねられることになる。すなわち、前中心Ｍの右側においては合計１４枚の生地が重ねられ、左側においては合計１０枚の生地が重ねられる。 When the upper end portion 1a is not continuous to the left and right in the front center M and is separated in the same manner as the region below the upper end portion 1a, the upper end portion 1a is separated from the region below the upper end portion 1a by folding back. Double the number of fabrics will be stacked. That is, a total of 14 fabrics are stacked on the right side of the front center M, and a total of 10 fabrics are stacked on the left side.
　このように、上端部１ａにおいて左右の生地を連続させる本実施形態によれば、上端部１ａにおいて重ねられる生地の枚数を半分に減らして、薄くすることができる。薄い上端部１ａは、突出する鼻及び湾曲する頬の形状に合わせて変形しやすく、凹凸を有する顔のラインに沿って密着する。したがって、鼻に当接する部分にワイヤ等を設けることなく、フィット性に優れたマスク１０を提供できる。 As described above, according to the present embodiment in which the left and right doughs are continuous at the upper end portion 1a, the number of doughs to be stacked at the upper end portion 1a can be reduced by half to make the dough thinner. The thin upper end portion 1a is easily deformed according to the shape of the protruding nose and the curved cheek, and adheres along the uneven face line. Therefore, it is possible to provide the mask 10 having excellent fit without providing a wire or the like in the portion in contact with the nose.
　上端部１ａの領域は、適宜設定することができる。例えば、上端部１ａは、本体部１の上端から０．５～３ｃｍ程度の領域である。なかでも上端部１ａは上端から０．７～１．５ｃｍの領域であることが好ましい。上端から０．７ｃｍ以上であれば、十分なフィット性が得られやすく、上端から１．５ｃｍ以下であれば過剰な密着を避けて呼吸しやすい空間が形成されやすい。 The area of the upper end portion 1a can be appropriately set. For example, the upper end portion 1a is a region of about 0.5 to 3 cm from the upper end of the main body portion 1. Above all, the upper end portion 1a is preferably a region of 0.7 to 1.5 cm from the upper end. If it is 0.7 cm or more from the upper end, it is easy to obtain a sufficient fit, and if it is 1.5 cm or less from the upper end, it is easy to form a space where it is easy to breathe while avoiding excessive adhesion.
　表面生地１１、フィルター１３及び裏面生地１２のサイズは、上記上端部１ａの領域のサイズに縫い代のサイズを考慮して決定することができる。 The sizes of the front surface fabric 11, the filter 13, and the back surface fabric 12 can be determined in consideration of the size of the region of the upper end portion 1a and the size of the seam allowance.
　以上のように、本実施形態によれば、表面生地１１、裏面生地１２及びフィルター１３は、上端部１ａが左右に連続し、上端部１ａより下方が左右に分離する形状を有する。マスク１０において、左右に分離された生地部分ｗ１及びｗ２は、前中心Ｍにおいて縫着されている。 As described above, according to the present embodiment, the front surface fabric 11, the back surface fabric 12, and the filter 13 have a shape in which the upper end portion 1a is continuous to the left and right and the lower end portion 1a is separated to the left and right. In the mask 10, the fabric portions w1 and w2 separated to the left and right are sewn at the front center M.
　このように生地が左右に分離されていない上端部１ａでは重なる生地の枚数が少なく、薄いため、突出する鼻及び湾曲する頬の形状に合わせて上端部１ａが変形しやすく、凹凸を有する顔のラインに沿って密着する。したがって、フィット性に優れたマスク１０を提供できる。 Since the number of overlapping fabrics is small and thin at the upper end portion 1a where the fabrics are not separated to the left and right, the upper end portion 1a is easily deformed according to the shape of the protruding nose and the curved cheeks, and the face has irregularities. Adhere along the line. Therefore, it is possible to provide the mask 10 having excellent fit.
　上端部１ａが薄いと、柔らかくなるため、顔から外したマスク１０を机の上に置いたときに自重によりマスク１０が折りたたまれやすい。顔と接触するマスク１０の後ろ側が露出しにくく、衛生的である。 If the upper end 1a is thin, it becomes soft, so when the mask 10 removed from the face is placed on the desk, the mask 10 is easily folded by its own weight. The back side of the mask 10 that comes into contact with the face is not easily exposed and is hygienic.
　また上端部１ａには伸縮テープ１４が設けられる。伸縮テープ１４により鼻や頬の曲面に本体部１の上端部１ａがよりフィットしやすくなる。さらに伸縮テープ１４によりテンションが加わり、上端部１ａより下方の生地が前側へ張り出しやすくなる。口周辺の空間が形成されやすく、呼吸による張り付きが減るため、マスク１０の着用感が向上する。 Further, an elastic tape 14 is provided on the upper end portion 1a. The elastic tape 14 makes it easier for the upper end portion 1a of the main body portion 1 to fit on the curved surface of the nose or cheek. Further, tension is applied by the elastic tape 14, and the fabric below the upper end portion 1a is easily projected to the front side. Since the space around the mouth is easily formed and the sticking due to breathing is reduced, the wearing feeling of the mask 10 is improved.
　マスク１０は、本体部１に編地を使用しており、洗濯可能である。汚れを落として繰り返し使用した場合も衛生性を維持することができる。 The mask 10 uses a knitted fabric for the main body 1 and is washable. Hygiene can be maintained even when the dirt is removed and used repeatedly.
　以上、本発明の好ましい実施形態について説明したが、本発明は、これらの実施形態に限定されず、その発明の範囲内で種々の変形及び変更が可能である。 Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and modifications can be made within the scope of the invention.
　例えば、表面生地１１の上端部１ａと裏面生地１２の上端部１ａとは、熱圧着により接合されていてもよい。熱圧着の場合、生地端のほつれがないため、縫い代が内側に位置するように上端部１ａを折り返す必要がない。 For example, the upper end portion 1a of the front surface fabric 11 and the upper end portion 1a of the back surface fabric 12 may be joined by thermocompression bonding. In the case of thermocompression bonding, since there is no fraying at the edges of the fabric, it is not necessary to fold back the upper end portion 1a so that the seam allowance is located inside.
　したがって、上端部１ａにおいて重なる生地の枚数を、縫着する場合の半分に減らすことができる。上端部１ａがより薄くなり、鼻への密着性が高まるため、フィット性により優れたマスク１０を提供できる。 Therefore, the number of overlapping fabrics at the upper end 1a can be reduced to half that of sewing. Since the upper end portion 1a becomes thinner and the adhesion to the nose is enhanced, it is possible to provide the mask 10 having a better fit.
　表面生地１１及び裏面生地１２の素材としては、ポリプロピレン等の熱可塑性樹脂のように熱圧着しやすい素材を選択することが好ましい。 As the material of the front surface fabric 11 and the back surface fabric 12, it is preferable to select a material that is easily thermocompression bonded, such as a thermoplastic resin such as polypropylene.
　本出願は、２０２０年１０月２７日に出願された日本特許出願である特願２０２０－１７９４５０号に基づく優先権を主張し、当該日本特許出願のすべての記載内容を援用する。 This application claims priority based on Japanese Patent Application No. 2020-179450, which is a Japanese patent application filed on October 27, 2020, and incorporates all the contents of the Japanese patent application.
