Description

マスクmask
　本発明は、着用者の顔面との間の空間の保持性が向上したマスクに関する。 The present invention relates to a mask having improved retention of space between the wearer's face.
　背景技術に係るマスクは、横方向に平行な複数のプリーツが設けられ、このプリーツを介して縦方向に展開することで前方に立体的に広がる構成である。このようなマスクの着用の際には、着用者とマスク本体との間には、複数のプリーツの展開により立体的に広がったマスク本体の形状に応じた空間が形成される。
　このような空間を安定して保持するための技術が開示されている。特許文献１には、マスクを長時間、使用しても、その口当て部の立体形状が保持されると共に、その立体形状が使用者の顔の大きさに簡単に調整することができる立体可変式の衛生用マスクが開示されている。特許文献１のマスクは、複数枚の不織布を重ね合わせた状態で左右方向に細長く延びる折り畳み部を有する扁平状の口当て部と、その口当て部の両側に有する耳に装着するための引っ掛け部とからなる立体可変式の衛生用マスクにおいて、前記折り畳み部の中に可撓性を有する形状保持部材を収容している立体可変式の衛生用マスクが開示されている。 The mask according to the background technique has a configuration in which a plurality of pleats parallel to each other in the horizontal direction are provided, and the mask expands in the vertical direction through the pleats to spread three-dimensionally forward. When wearing such a mask, a space is formed between the wearer and the mask body according to the shape of the mask body which is three-dimensionally expanded by the development of a plurality of pleats.
A technique for stably holding such a space is disclosed. According to Patent Document 1, even if the mask is used for a long time, the three-dimensional shape of the mouthpiece is maintained and the three-dimensional shape can be easily adjusted to the size of the user's face. The formula hygiene mask is disclosed. The mask of Patent Document 1 has a flat mouthpiece having a folded portion extending in the left-right direction in a state where a plurality of non-woven fabrics are stacked, and hooks for attaching to the ears held on both sides of the mouthpiece.

　特許文献１では、形状維持のための可撓性を有する形状保持部材を要するため、この部材をマスク本来の機能となるフィルタとしての複数枚の不織布に別途加えてマスク本体に配置する構成であることから、製造工程が複雑化して手間がかかり、更に、この部材を用意するための材料コストと共に製造コストがかかるという課題があった。また、特許文献１のマスクは、複数枚の不織布とは異なり通気性のない形状保持部材が収容されて構成されることから、マスクの通気性を低下させるという課題があった。
　本発明は、前述のような課題を解決するためになされたもので、マスク本体の通気性を阻害することなく、より容易に、より安価に、着用者とマスク本体との間の空間を安定して維持できるマスクを提供することを目的とする。 In Patent Document 1, since a shape-retaining member having flexibility for maintaining the shape is required, this member is separately added to a plurality of non-woven fabrics as a filter which is an original function of the mask and arranged on the mask body. Therefore, there is a problem that the manufacturing process is complicated and time-consuming, and further, the manufacturing cost is high as well as the material cost for preparing this member. Further, unlike a plurality of non-woven fabrics, the mask of Patent Document 1 is configured by accommodating a shape-retaining member having no air permeability, and therefore has a problem of reducing the air permeability of the mask.
The present invention has been made to solve the above-mentioned problems, and stabilizes the space between the wearer and the mask body more easily and cheaply without impairing the air permeability of the mask body. The purpose is to provide a mask that can be maintained.
　本発明に係るマスクは、マスク本体と、前記マスク本体の折り畳み、及び、展開に用いられ、前記マスク本体に設けられた複数のプリーツと、前記マスク本体の一部が固定された線状の固定部であって、前記複数のプリーツに含まれるプリーツ上、若しくは、前記プリーツの近傍に前記プリーツに沿って、前記マスク本体の側端側から前記マスク本体の側方向中央に向かって延出して設けられた延設固定部と、を備えるものである。
　このように、本発明に係るマスクは、マスク本体のプリーツに沿う延設固定部を備える。そのため、対応するプリーツの近傍部分は、固定により硬化する。この結果、対応するプリーツは、マスク本体の展開状態における形状をより安定して保持する。結果として、マスク本体は、折り畳みによる剛性の強化と共に、この折り畳みで形成されたプリーツ上、若しくは、この近傍における固定による硬化と相俟って、着用者の顔面との間の空間をより安定して保持する。すなわち、本発明に係るマスクは、マスク本体の展開状態の形状を維持するための追加の形状保持部材を要せず、マスク本体の通気性を阻害することなく、延設固定部を介してマスク本体と着用者の顔面との間の空間を保持する。このように、本発明に係るマスクは、形状保持部材をマスク本体に配置する手間、及び、形状保持部材にかかる材料コスト及び製造コストを抑制でき、マスク本体の通気性を阻害することなく、より容易に、より安価にマスク本体と着用者の顔面との間の空間をより安定して保持できる。 The mask according to the present invention is used for folding and unfolding the mask main body, the mask main body, and a plurality of pleats provided on the mask main body, and a linear fixing in which a part of the mask main body is fixed. A portion, which is provided on the pleats included in the plurality of pleats or in the vicinity of the pleats so as to extend from the side end side of the mask body toward the center in the lateral direction of the mask body along the pleats. It is provided with an extended fixing portion.
As described above, the mask according to the present invention includes an extension fixing portion along the pleats of the mask body. Therefore, the vicinity of the corresponding pleats is hardened by fixing. As a result, the corresponding pleats more stably retain the shape of the mask body in the unfolded state. As a result, the mask body becomes more stable in the space between the wearer's face and the wearer's face, combined with the increased rigidity of the folds and the hardening of the pleats formed by the folds or in the vicinity of the pleats. Hold. That is, the mask according to the present invention does not require an additional shape-retaining member for maintaining the shape of the mask body in the unfolded state, and does not impede the air permeability of the mask body, and the mask is passed through the extended fixing portion. Maintains space between the body and the wearer's face. As described above, the mask according to the present invention can reduce the trouble of arranging the shape-retaining member on the mask body, the material cost and the manufacturing cost of the shape-retaining member, and can further reduce the air permeability of the mask body. The space between the mask body and the wearer's face can be easily and inexpensively maintained more stably.
　また、本発明に係るマスクは、必要に応じて、前記延設固定部が、前記マスク本体の一部が溶着により硬化されることで、前記マスク本体の一部が固定されて形成されていることが好ましい。
　前記延設固定部は、溶着により硬化されることで、より適切に硬化する。これにより、本発明に係るマスクは、マスク本体と着用者の顔面との間の空間をより安定して保持できる。 Further, the mask according to the present invention is formed by fixing a part of the mask main body by hardening a part of the mask main body by welding to the extended fixing portion, if necessary. Is preferable.
The extended fixing portion is cured by welding to be cured more appropriately. Thereby, the mask according to the present invention can more stably hold the space between the mask body and the wearer's face.
　また、本発明に係るマスクは、必要に応じて、前記マスク本体が、複数のシート体が積層されて形成され、前記延設固定部が、前記複数のシート体のうち前記マスクの着用の際における着用者の顔面と反対側の最外層のシート体を含まないように設けられていることが好ましい。
　マスク本体における着用者の顔面と反対側の最外層のシート体に延設固定部が設けられていないため、外から延設固定部を見えなくできる。これにより、本発明に係るマスクは、着用の際のマスクの見栄えを向上できる。 Further, in the mask according to the present invention, if necessary, the mask body is formed by laminating a plurality of sheet bodies, and the extended fixing portion is formed when the mask is worn among the plurality of sheet bodies. It is preferable that the sheet body of the outermost layer on the opposite side of the wearer's face is not included.
Since the extending fixing portion is not provided on the outermost sheet body on the opposite side of the mask body from the wearer's face, the extending fixing portion can be made invisible from the outside. Thereby, the mask according to the present invention can improve the appearance of the mask when worn.
　また、本発明に係るマスクは、必要に応じて、前記延設固定部が、前記マスク本体の側端側から前記マスク本体の側方向中央に向かって延出し、前記マスク本体の側方向中央まで延出しないことが好ましい。
　これにより、延設固定部それぞれは、マスク本体の両側に間隔を置いて配置された２つの固定部を備えることとなる。延設固定部それぞれは、この２つの固定部を介して、マスク本体の形状を保持する。仮に、マスク本体における側方向片側に変形が生じた場合、この２つの固定部の一方の近傍に変形が生じる。この場合、この２つの固定部は、間隔を空けているため、他方の固定部には変形の影響が伝搬しにくい。
　対して、延設固定部が、両側の側端側からそれぞれマスク本体の側方向中央まで延出した固定部を備える場合、延設固定部は、一方の側端側から他方の側端側にわたって設けられる。これにより、マスク本体の側方向片側で変形が生じた場合、延設固定部を介して変形の影響がマスク本体の他方の側方向片側にも伝搬することとなる。このため、延設固定部は、マスク本体を支持し、マスク本体の両側に間隔を置いて配置された２つの固定部を備えることで、より安定してマスク本体と顔面との間の空間を保持できる。 Further, in the mask according to the present invention, if necessary, the extension fixing portion extends from the side end side of the mask body toward the center of the mask body in the lateral direction to the center of the mask body in the side direction. It is preferable not to extend.
As a result, each of the extended fixing portions is provided with two fixing portions arranged at intervals on both sides of the mask main body. Each of the extended fixing portions holds the shape of the mask body via these two fixing portions. If deformation occurs on one side of the mask body in the lateral direction, deformation occurs in the vicinity of one of the two fixing portions. In this case, since the two fixed portions are spaced apart from each other, the influence of deformation is unlikely to propagate to the other fixed portion.
On the other hand, when the extension fixing portion includes a fixing portion extending from the side end sides on both sides to the center in the lateral direction of the mask body, the extension fixing portion extends from one side end side to the other side end side. Provided. As a result, when deformation occurs on one side of the mask body in the lateral direction, the effect of the deformation is propagated to one side in the other side of the mask body via the extension fixing portion. For this reason, the extended fixing portion supports the mask main body and is provided with two fixing portions arranged at intervals on both sides of the mask main body to provide a more stable space between the mask main body and the face. Can be retained.
　また、本発明に係るマスクは、必要に応じて、前記延設固定部が、前記マスク本体における前記複数のプリーツで区切られた複数の領域のうち、前記マスクの着用の際に着用者の口に対向する領域である対向領域を挟む２つのプリーツ上、若しくは、前記２つのプリーツそれぞれの近傍に設けられていることが好ましい。
　着用者がマスク本体を着用している場合、マスク本体が着用者の口に接触すると着用者に不快感が生じたり、口の化粧、リップクリーム等が落ちたりする事態が生じる。対向領域を挟むプリーツ上、若しくは、この近傍に延設固定部が設けられることで、本発明に係るマスクは、着用者の口とマスク本体との間により安定して空間を保持し、このような事態が生じることを抑制できる。 Further, in the mask according to the present invention, if necessary, the extension fixing portion is the mouth of the wearer when the mask is worn, out of a plurality of regions in the mask body separated by the plurality of pleats. It is preferable that the pleats are provided on two pleats sandwiching the facing region, which is a region facing the pleats, or in the vicinity of each of the two pleats.
When the wearer wears the mask body, if the mask body comes into contact with the wearer's mouth, the wearer may feel uncomfortable, or the makeup of the mouth, lip balm, etc. may come off. By providing an extended fixing portion on or near the pleats sandwiching the facing region, the mask according to the present invention maintains a more stable space between the wearer's mouth and the mask body. It is possible to suppress the occurrence of such a situation.
　また、本発明に係るマスクは、必要に応じて、前記延設固定部が、更に、前記複数の領域のうち前記対向領域に隣接する領域を挟む２つのプリーツのうち前記対向領域と逆方向に位置するプリーツ上、若しくは、この近傍にも設けられていることが好ましい。
　対向領域に隣接する領域を挟む２つのプリーツのうち対向領域と逆方向に位置するプリーツの近傍に延設固定部を設けることで、対向領域の直近の４つのプリーツについて、展開状態における形状を保持でき、より安定して、マスク本体と着用者の顔面との間の空間を保持できる。 Further, in the mask according to the present invention, if necessary, the extension fixing portion further, in the direction opposite to the facing region of the two pleats that sandwich the region adjacent to the facing region of the plurality of regions. It is preferably provided on or near the pleats where it is located.
By providing an extension fixing portion in the vicinity of the pleats located in the opposite direction to the facing region among the two pleats sandwiching the region adjacent to the facing region, the shape of the four pleats closest to the facing region in the deployed state is maintained. It can and more stably maintain the space between the mask body and the wearer's face.
　また、本発明に係るマスクは、必要に応じて、前記複数のプリーツが、折りたたみ状態の前記マスク本体における前記マスクの着用者の顔面と対向しない方の表面において、前記複数の領域のうち前記複数のプリーツが折り畳まれた状態における前記マスク本体の上下方向中央を含む中央領域に対して上側には上向きの１つ以上のヒダ山が形成され、前記中央領域の下側には下向きの１つ以上のヒダ山が形成されるように設けられ、前記対向領域が、前記中央領域であり、前記延設固定部が、前記中央領域を囲む２つのプリーツの近傍であって、前記中央領域の外部に設けられていることが好ましい。
　マスク本体の複数のプリーツがこのように設けられているため、プリーツの展開状態において、対向領域は、最も前方に配置される。そして、延設固定部は、対向領域を挟むプリーツ近傍で、対向領域の外部に設けられるため、背面側から前面側の対向領域を支持する。これにより、本発明に係るマスクは、対向領域の形状をプリーツの展開状態の形状により安定して維持し、マスク本体と着用者の顔面との間の空間をより安定して保持できる。 Further, in the mask according to the present invention, if necessary, the plurality of pleats among the plurality of regions on the surface of the mask body in a folded state which does not face the face of the wearer of the mask. One or more upward folds are formed on the upper side of the central region including the vertical center of the mask body in the folded state of the pleats, and one or more downward folds are formed on the lower side of the central region. The facing region is the central region, and the extension fixing portion is in the vicinity of two pleats surrounding the central region and outside the central region. It is preferable that it is provided.
Since the plurality of pleats of the mask body are provided in this way, the facing regions are arranged in the foremost position in the unfolded state of the pleats. Since the extended fixing portion is provided outside the facing region in the vicinity of the pleats sandwiching the facing region, the extending fixing portion supports the facing region from the back side to the front side. As a result, the mask according to the present invention can stably maintain the shape of the facing region by the shape of the pleats in the unfolded state, and can more stably maintain the space between the mask body and the wearer's face.
　また、本発明に係るマスクは、必要に応じて、前記対向領域に、前記マスク本体の一部が固定されたＸ字状の固定部であって、前記マスク本体の一方の側端側から他方の側端側へ延出する２つの交差する線状の固定部から形成される固定部であるＸ字状固定部を更に備えることが好ましい。
　本発明に係るマスクは、更に、対向領域内に設けられたＸ字状固定部を介して、マスク本体における対向領域の部分を展開状態の形状に保持することで、より安定して、マスク本体と着用者の顔面との間の空間を保持できる。 Further, the mask according to the present invention is an X-shaped fixing portion in which a part of the mask body is fixed to the facing region, if necessary, from one side end side of the mask body to the other. It is preferable to further include an X-shaped fixing portion which is a fixing portion formed from two intersecting linear fixing portions extending toward the side end side of the above.
Further, the mask according to the present invention is more stable by holding the portion of the facing region in the mask main body in the unfolded shape via the X-shaped fixing portion provided in the facing region, so that the mask main body is more stable. The space between the wearer's face and the wearer's face can be maintained.
　また、本発明に係るマスクは、必要に応じて、前記対向領域内に、前記マスク本体の一部が固定された線状の固定部であって、前記対向領域における上下方向の中部に、前記マスク本体の側端部から前記マスク本体の側方向中央に向かって延出して設けられた固定部である線状固定部を更に備えることが好ましいものである。
　本発明に係るマスクは、更に、対向領域内に設けられた線状固定部を介して、マスク本体における対向領域の部分を、展開状態の形状に保持することで、より安定して、マスク本体と着用者の顔面との間の空間を保持できる。 Further, the mask according to the present invention is, if necessary, a linear fixing portion in which a part of the mask body is fixed in the facing region, and the mask is located in the middle portion in the vertical direction in the facing region. It is preferable to further provide a linear fixing portion which is a fixing portion provided so as to extend from the side end portion of the mask body toward the center in the lateral direction of the mask body.
Further, the mask according to the present invention is more stable by holding the portion of the facing region in the mask main body in the unfolded shape via the linear fixing portion provided in the facing region, so that the mask main body is more stable. The space between the wearer's face and the wearer's face can be maintained.
　また、本発明に係るマスクは、必要に応じて、前記マスク本体における、前記マスク本体の側方下部に設けられた、前記複数のプリーツの一部を介した展開ができないように前記マスク本体を拘束する下方拘束部を更に備えるものである。

　図３を用いて、マスク１の使用の際の状況について説明する。
　図３に、着用者に着用された状態におけるマスク１の断面Ａにおける端面図を示す。図３に示すように、プリーツ１１５それぞれが展開することで、マスク本体１１が前方に向かって広がっていることが分かる。着用状態のマスク本体１１は、上端部が着用者の鼻部に接触し、下端部が着用者の顎部に接触するように、着用者の顔面に配置されている。この状態で、着用者が息を吸うとマスク本体１１が着用者の顔面の方向に吸い寄せられ、マスク本体１１と着用者の顔面との間に形成された空間が保持できずに、マスク本体１１が着用者の顔面に接触する場合がある。マスク本体１１が着用者の顔面に接触すると着用者に不快感が生じたり、化粧等が落ちたりする事態が生じうるため、この空間が安定して保持されることが望ましい。 The situation when the mask 1 is used will be described with reference to FIG.
FIG. 3 shows an end view of the mask 1 in a cross section A when worn by the wearer. As shown in FIG. 3, it can be seen that the mask main body 11 spreads forward as each of the pleats 115 unfolds. The mask body 11 in the worn state is arranged on the wearer's face so that the upper end portion contacts the wearer's nose portion and the lower end portion contacts the wearer's chin portion. In this state, when the wearer inhales, the mask body 11 is attracted toward the wearer's face, and the space formed between the mask body 11 and the wearer's face cannot be maintained, so that the mask body 11 cannot be maintained. May come into contact with the wearer's face. When the mask body 11 comes into contact with the wearer's face, the wearer may feel uncomfortable or the makeup or the like may come off. Therefore, it is desirable that this space be stably maintained.
　本実施形態のマスク本体１１のプリーツ１１５Ｃ～１１５Ｅの近傍には、延設固定部１１６Ａ～Ｄが設けられている。そのため、プリーツ１１５Ｃ～１１５Ｅの近傍部分は、延設固定部１１６における固定（本実施形態では、溶着）により硬化している。このように、マスク１は、プリーツ１１５における折り畳みによる剛性の強化と共に、延設固定部１１６における固定による硬化と相俟って、プリーツ１１５が展開されたマスク本体１１の形状をより安定して保持する。この結果、マスク１は、マスク本体１１と着用者の顔面との間の空間をより安定して保持できる。 Extension fixing portions 116A to D are provided in the vicinity of the pleats 115C to 115E of the mask main body 11 of the present embodiment. Therefore, the portion in the vicinity of the pleats 115C to 115E is hardened by fixing (welding in this embodiment) in the extended fixing portion 116. In this way, the mask 1 holds the shape of the mask body 11 in which the pleats 115 are deployed more stably, in combination with the strengthening of the rigidity by folding the pleats 115 and the hardening by the fixing in the extended fixing portion 116. do. As a result, the mask 1 can more stably hold the space between the mask body 11 and the wearer's face.
　また、本実施形態では、延設固定部１１６Ｂ、１１６Ｃは、対向領域である中央領域を挟む２つのプリーツ１１５の近傍に設けられている。
　着用者がマスク１を着用している場合、マスク本体１１が着用者の口に接触するとマスク本体１１が顔面の他の部分に接触する場合よりも強い不快感が生じたり、口の化粧、リップクリーム等が落ちたりする事態が生じる。マスク１は、対向領域を挟むプリーツ１１５の近傍に延設固定部１１６が設けられることで、対向領域と口との間の空間をより安定して保持し、このような事態が生じることを抑制できる。
　また、マスク本体１１は、延設固定部１１６Ｂ、１１６Ｃに加えて、対向領域に隣接する領域における対向領域と逆方向のプリーツ１１５Ｃ、１１５Ｆそれぞれの近傍に設けられた延設固定部１１６Ａ、１１６Ｄを備える。すなわち、延設固定部１１６Ａ～１１６Ｄは、対向領域の直近の４つのプリーツ１１５の近傍に設けられる。これにより、延設固定部１１６Ａ～１１６Ｄは、延設固定部１１６Ｂ、１１６Ｃしか設けられない場合に比べて、より安定して、マスク本体１１と着用者の顔面との間の空間を保持できる。 Further, in the present embodiment, the extension fixing portions 116B and 116C are provided in the vicinity of the two pleats 115 that sandwich the central region which is the opposite region.
When the wearer wears the mask 1, when the mask body 11 comes into contact with the wearer's mouth, it causes stronger discomfort than when the mask body 11 touches other parts of the face, and the makeup and lip of the mouth. The cream etc. may fall off. The mask 1 is provided with an extension fixing portion 116 in the vicinity of the pleats 115 sandwiching the facing region, so that the space between the facing region and the mouth is more stably maintained, and such a situation is suppressed. can.
Further, in addition to the extension fixing portions 116B and 116C, the mask main body 11 includes extension fixing portions 116A and 116D provided in the vicinity of the pleats 115C and 115F in the opposite direction to the facing region in the region adjacent to the facing region. Be prepared. That is, the extension fixing portions 116A to 116D are provided in the vicinity of the four pleats 115 closest to the facing region. As a result, the extended fixing portions 116A to 116D can maintain the space between the mask main body 11 and the wearer's face more stably as compared with the case where only the extended fixing portions 116B and 116C are provided.
　また、本実施形態では、複数のプリーツ１１５は、対向領域である中央領域を基準に上方向にマスク本体１１の前方の表面において上向きのヒダ山が形成され、中央領域を基準に下方向にマスク本体１１の前方の表面において下向きのヒダ山が形成されるように設けられている。そのため、図３に示すように、プリーツ１１５の展開状態において、対向領域は、最も前方に突出することとなる。また、対向領域を挟むプリーツ１１５の近傍に設けられる延設固定部１１６Ｂ、１１６Ｃは、それぞれ対向領域の外側に設けられている。そのため、延設固定部１１６Ｂ、１１６Ｃは、最前面に位置する対向領域を背面側から支持することとなる。これにより、マスク１は、対向領域の形状をプリーツ１１５の展開状態の形状により安定して維持し、マスク本体１１と着用者の顔面との間の空間をより安定して保持できる。 Further, in the present embodiment, the plurality of pleats 115 have upward folds formed on the surface in front of the mask main body 11 with reference to the central region, which is the opposite region, and mask downward with reference to the central region. It is provided so that downward folds are formed on the front surface of the main body 11. Therefore, as shown in FIG. 3, in the deployed state of the pleats 115, the facing region protrudes most forward. Further, the extension fixing portions 116B and 116C provided in the vicinity of the pleats 115 sandwiching the facing region are provided outside the facing region, respectively. Therefore, the extended fixing portions 116B and 116C support the facing region located at the foremost surface from the back surface side. As a result, the mask 1 can stably maintain the shape of the facing region by the shape of the pleats 115 in the unfolded state, and can more stably maintain the space between the mask main body 11 and the wearer's face.
　本実施形態では、延設固定部１１６は、マスク本体１１の積層された複数のシート体のうち、最前面のシート体を含まないように設けられている。そのため、使用状態において、外部から延設固定部１１６は、視認できない。マスク本体１１の前面側の固定部は、マスク１の使用状態において、外部から見れば見苦しさを喚起する場合がある。そのため、本実施形態のマスク１は、延設固定部１１６が外部から見えないようにすることで、使用状態におけるマスク１の見栄えを向上できる。 In the present embodiment, the extended fixing portion 116 is provided so as not to include the frontmost sheet body among the plurality of laminated sheet bodies of the mask main body 11. Therefore, in the used state, the extended fixing portion 116 cannot be visually recognized from the outside. The fixed portion on the front surface side of the mask main body 11 may arouse unsightly when viewed from the outside when the mask 1 is in use. Therefore, in the mask 1 of the present embodiment, the appearance of the mask 1 in the used state can be improved by making the extended fixing portion 116 invisible from the outside.
　以上、本実施形態のマスク１は、延設固定部１１６を介して、マスク本体１１のプリーツ１１５に沿う延設固定部１１６を介して、マスク本体１１と着用者の顔面との間の空間をより安定して保持できる。すなわち、本発明に係るマスク１は、マスク本体１１の展開状態の形状を維持するための追加の形状保持部材を要せず、延設固定部１１６を介してマスク本体１１と着用者の顔面との間の空間を保持する。このように、マスク１は、形状保持部材をマスク１に配置することで生じる通気性の低下を防止しつつ、形状保持部材をマスク本体１１に配置する手間、及び、形状保持部材にかかる材料コスト、製造コストを要さず、より容易に、より安価にマスク本体１１と着用者の顔面との間の空間をより安定して保持できる。 As described above, the mask 1 of the present embodiment provides a space between the mask body 11 and the wearer's face via the extension fixing portion 116 and the extension fixing portion 116 along the pleats 115 of the mask body 11. Can be held more stably. That is, the mask 1 according to the present invention does not require an additional shape-retaining member for maintaining the shape of the mask body 11 in the unfolded state, and the mask body 11 and the wearer's face are connected to the mask body 11 via the extension fixing portion 116. Keep the space between. As described above, the mask 1 prevents the decrease in air permeability caused by arranging the shape-retaining member on the mask 1, the trouble of arranging the shape-retaining member on the mask main body 11, and the material cost for the shape-retaining member. The space between the mask body 11 and the wearer's face can be more stably maintained more easily and cheaply without requiring a manufacturing cost.
　本実施形態では、延設固定部１１６は、マスク本体１１の両側の側端拘束部１１４それぞれにおけるマスク本体１１の上下方向の同じ位置それぞれから前記マスク本体１１の側方向中央まで延出し、結果として、一方の側端拘束部１１４から他方の側端拘束部１１４にわたって延出していることとした。ただし、延設固定部１１６は、マスク本体１１の側端側からマスク本体１１の側方向中央に向かって延出し、マスク本体１１の側方向中央まで延出しないように設けられてもよい。
　これにより、延設固定部１１６は、側端拘束部１１４を基準にマスク本体１１を支持し、マスク本体１１の両側に間隔を置いて配置された２つの溶着部を備えることとなる。延設固定部１１６は、この２つの溶着部を介して、マスク本体１１の形状を保持する。仮に、マスク本体１１における側方向片側に変形が生じた場合、この２つの溶着部の一方の近傍に変形が生じる。この場合、この２つの溶着部は間隔を置いて設けられているため、他方の溶着部には変形の影響が伝搬しにくい。対して、延設固定部１１６が、一方の側端拘束部１１４から他方の側端拘束部１１４にわたって設けられている場合、マスク本体１１における側方向片側に変形が生じると、延設固定部１１６を介して変形の影響がマスク本体１１の他方の側方片側に伝搬しやすくなる。このため、延設固定部１１６は、側端拘束部１１４を基準にマスク本体１１を支持し、マスク本体１１の両側に間隔を置いて配置された２つの溶着部を備えることで、より安定してマスク本体１１と顔面との間の空間を保持できる。 In the present embodiment, the extended fixing portion 116 extends from the same vertical position of the mask main body 11 in each of the side end restraint portions 114 on both sides of the mask main body 11 to the center in the lateral direction of the mask main body 11, as a result. , It was decided to extend from one side end restraint portion 114 to the other side end restraint portion 114. However, the extension fixing portion 116 may be provided so as to extend from the side end side of the mask main body 11 toward the center of the mask main body 11 in the lateral direction and not to extend to the center of the mask main body 11 in the lateral direction.
As a result, the extended fixing portion 116 supports the mask main body 11 with reference to the side end restraint portion 114, and includes two welding portions arranged at intervals on both sides of the mask main body 11. The extended fixing portion 116 holds the shape of the mask main body 11 via the two welding portions. If deformation occurs on one side of the mask body 11 in the lateral direction, deformation occurs in the vicinity of one of the two welded portions. In this case, since the two welded portions are provided at intervals, the influence of deformation is unlikely to propagate to the other welded portion. On the other hand, when the extension fixing portion 116 is provided from one side end restraint portion 114 to the other side end restraint portion 114, when deformation occurs on one side in the side direction of the mask main body 11, the extension fixing portion 116 The effect of deformation is likely to propagate to the other side of the mask body 11 via. Therefore, the extended fixing portion 116 is more stable by supporting the mask main body 11 with reference to the side end restraint portion 114 and providing two welding portions arranged at intervals on both sides of the mask main body 11. The space between the mask body 11 and the face can be maintained.

The mask 4 of the present embodiment will be described with reference to FIG. FIG. 6 shows a front view of the mask 4 in a folded state. The direction in which the mask 4 comes into contact with the wearer's face when worn is the back side, and the opposite direction is the front side. Further, the upward direction and the downward direction of the mask 4 when worn are defined as upward and downward, respectively.
In FIG. 6, the mask 4 is the same elements 41 to 44, 411 to 414, 415 as the elements 11 to 14, 111 to 114, 115 (115A to 115H), 116 (116A to 116D) of the mask 1 of the first embodiment. (415A to 415H), 416 (416A to 416D), and further restrain the mask body 41 so that it cannot be deployed through a part of a plurality of pleats 415 provided at the lower side of the mask body 41. A lower restraint portion 417 is provided.
　本実施形態では、下方拘束部４１７は、マスク本体４１の側方下部に設けられている。より詳細には、下方拘束部４１７は、折り畳み状態のマスク本体４１における中央領域よりも下のプリーツ４１５Ｇとプリーツ４１５Ｈとの間の位置であって、マスク本体４１の側方向中央と側方拘束部４１４それぞれとの間の位置に設けられている。下方拘束部４１７は、マスク本体４１の厚さ方向に重なっている全てのシート体を一体とするよう溶着することで設けられており、プリーツ４１５Ｇとプリーツ４１５Ｈとを介した展開ができないようにマスク本体４１を拘束する。これにより、下方拘束部４１７から下であり、且つ、下方拘束部４１７よりもマスク本体４１の横方向外側であるマスク本体４１の部分は、プリーツ４１５Ｇとプリーツ４１５Ｈとを介して展開できなくなる。 In the present embodiment, the lower restraint portion 417 is provided on the lower side of the mask main body 41. More specifically, the lower restraint portion 417 is a position between the pleats 415G and the pleats 415H below the central region of the folded mask main body 41, and is a lateral center and lateral restraint portion of the mask main body 41. It is provided at a position between each of the 414s. The lower restraint portion 417 is provided by welding all the sheet bodies overlapping in the thickness direction of the mask body 41 into one body, and is a mask so as not to be deployed via the pleats 415G and the pleats 415H. Restrain the main body 41. As a result, the portion of the mask body 41 that is below the lower restraint portion 417 and laterally outside the mask body 41 from the lower restraint portion 417 cannot be deployed via the pleats 415G and the pleats 415H.
　このように、下方拘束部４１７が設けられることにより、下方拘束部４１７よりも下側、且つ、外側の部分でプリーツ４１５が展開しなくなる。

　以上、本実施形態のマスク４は、下方拘束部４１７によりマスク本体４１をより顎部分にフィットさせつつ、延設固定部４１６により、より安定してマスク本体４１と着用者の顔面との間の空間を保持する。すなわち、マスク４は、マスク本体４１と着用者の顔面との間により適切な空間をより安定して保持できる。 By providing the lower restraint portion 417 in this way, the pleats 415 do not expand in the portion below and outside the lower restraint portion 417.
On the face, the width of the face becomes narrower as it approaches the chin from the mouth. The lower restraint portion 417 prevents the mask body 41 from being pleated unfolded at a portion below and outside the lower restraint portion 417. As a result, the lower restraint portion 417 suppresses the spread in the unfolded state of the pleats 415 at a portion below and outside the lower restraint portion 417 in the mask main body 41. As a result, the space formed by the mask body 41 when the pleats 415 is deployed is lower than the lower restraint portion 417 and the outer portion is narrower so as to fit the shape of the wearer's jaw better. Become.
As described above, in the mask 4 of the present embodiment, the mask main body 41 is more stably fitted to the chin portion by the lower restraint portion 417, and the mask main body 41 is more stably between the mask main body 41 and the wearer's face by the extended fixing portion 416. Hold space. That is, the mask 4 can more stably hold a more appropriate space between the mask body 41 and the wearer's face.
