本発明において、「３面折り畳み式マスク」という用語は、図３乃至図５に示すように、（ｉ）マスクの中央部に位置する中央フィルター紙２、（ｉｉ）前記中央フィルター紙２の上方に延設されて折り曲げ線７ａに沿って中央フィルター紙２の長さ方向に折り畳まれる上部フィルター紙１、（ｉｉｉ）前記中央フィルター紙２の下方に延設されて折り曲げ線７ｂに沿って中央フィルター紙２の長さ方向に折り畳まれる下部フィルター紙３、（ｉｖ）前記上部フィルター紙１の中央内部に挿設されているアルミ平板の鼻掛け金具４と、（ｖ）前記中央フィルター紙２の両端部のそれぞれに設けられる２つの耳掛け紐５と、を含み、マスクの長さ方向に沿って3重に折り畳むことができるマスクを称するものとして使用する。 In the present invention, as shown in FIGS. 3 to 5, the term “three-side foldable mask” refers to (i) a central filter paper 2 located at the center of the mask, and (ii) above the central filter paper 2. An upper filter paper 1 extending in the length direction of the central filter paper 2 along the fold line 7a, and (iii) extending below the central filter paper 2 and extending along the fold line 7b. A lower filter paper 3 that is folded in the length direction of the paper 2; (iv) an aluminum flat nose hanger 4 that is inserted inside the center of the upper filter paper 1; and (v) both ends of the central filter paper 2 And two ear hook straps 5 provided in each of the parts, and used as a mask that can be folded three times along the length of the mask.
最近は、便利に携帯や保管できるように３面折り畳み式マスクが広く使用されている。 Recently, a three-side foldable mask has been widely used for convenient carrying and storage.
マスクは大きく保健用の衛生マスクと産業用の防塵マスクに大別される。 Masks can be broadly divided into health hygiene masks and industrial dust masks.
衛生マスクは日常生活の中で多く使用されている。最近、頻繁な黄砂風のため大気汚染が日増しにひどくなっているため、一般人も健康上の理由でマスクを多く着用している実情である。 Sanitary masks are often used in daily life. In recent years, air pollution has become more and more severe due to frequent yellow sand winds, so the general public is also wearing a lot of masks for health reasons.
防塵マスクは有毒ガスの排出が激しい化学工程、金属粉の発生が非常に多い金属製錬工場、粉塵発生が非常に多い紡織工場などの産業現場で作業者の健康のために多く使用されている。 Dust masks are often used for workers' health in industrial sites such as chemical processes where toxic gas emissions are intense, metal smelting plants where metal dust is very much generated, and textile factories where dust is very much generated. .
従来の折り畳み式マスクとしては、図１及び図２に示すように、中央フィルター紙２、前記中央フィルター紙２の上方に延設された上部フィルター紙１、及び前記中央フィルター紙２の下方に延設された下部フィルター紙３を含む３面折り畳み式マスクが使用されてきた。 As shown in FIGS. 1 and 2, the conventional folding mask includes a central filter paper 2, an upper filter paper 1 extending above the central filter paper 2, and a lower part of the central filter paper 2. A three-sided foldable mask has been used that includes the lower filter paper 3 provided.
前記従来の３面折り畳み式マスクは、上部フィルター紙１の中央上端部に鼻掛け金具４が設けられており、中央のフィルター紙２の両端部には、耳掛け紐５が連結された構造を有する。 The conventional three-side foldable mask has a structure in which a nose hanger 4 is provided at the center upper end of the upper filter paper 1, and ear hook strings 5 are connected to both ends of the center filter paper 2. Have.
しかし、前記従来の３面折り畳み式マスクは着用者の鼻面及び頬骨部分に密着される上部フィルター紙１の上段部分と、着用者の顎線部分に密着される下部フィルター紙３の下段部分が不織布または不織布積層体からなっているため、弾性が不足している。その結果、着用者の顔面屈曲に沿って完全に密着されないため、微細粉塵の濾過性能が低下する問題があった。 However, the conventional three-side foldable mask has a nonwoven fabric in which the upper part of the upper filter paper 1 that is in close contact with the wearer's nose and cheekbones and the lower part of the lower filter paper 3 that is in close contact with the jawline of the wearer Or since it consists of a nonwoven fabric laminated body, elasticity is insufficient. As a result, there is a problem that the filtration performance of fine dust is deteriorated because it is not completely adhered along the bending of the face of the wearer.
また、前記従来の３面折り畳み式マスクは、図１及び図２に示すように、中央フィルター紙２の両端上縁部２ａと両端下縁部２ｂが耳掛け紐５の方向に沿って同じ長さに延びているため、着用者のＶ字状の顔形態に完全に密着されない。それによって、微細粉塵の濾過性能が低下する問題があった。 In addition, the conventional three-side foldable mask has the same length of the upper edge 2a and the lower edge 2b of the center filter paper 2 along the direction of the ear strap 5 as shown in FIGS. Therefore, it is not completely adhered to the wearer's V-shaped face form. As a result, there has been a problem that the filtration performance of fine dust is lowered.
参考に、マスクを着用する人は通常、Ｖ字状の顔形態、つまり頬骨部分は広いが、顎部分は狭いＶ字状の顔形態を有している。そのため、マスクが着用者の顔屈曲に沿って完全に密着されるためには、中央フィルター紙２の両端上縁部２ａが中央フィルター紙２の両端下縁部２ｂより耳掛け紐５の方向に相対的に長く突設することが好ましい。しかし、前記従来の３面折り畳み式マスクは前述のような要件を備えていなかった。 For reference, a person wearing a mask usually has a V-shaped facial form, that is, a cheekbone part is wide but a chin part has a narrow V-shaped facial form. Therefore, in order for the mask to be completely adhered along the bend of the wearer's face, the upper edge portions 2a at both ends of the central filter paper 2 are in the direction of the ear strap 5 from the lower edge portions 2b at both ends of the central filter paper 2. It is preferable to project relatively long. However, the conventional three-side foldable mask does not have the above-described requirements.
本発明は前述の問題点に鑑みてなされたものであり、その目的は、着用者の顔面屈曲に沿ってマスクが完全に密着されて微細粉塵の濾過性能がさらに向上し、携帯や保管が容易であり、着用感及び外観に優れた３面折り畳み式マスクを提供することにある。 The present invention has been made in view of the above-described problems, and its purpose is to further improve the filtering performance of fine dust by fully attaching the mask along the bending of the face of the wearer, and easy to carry and store.
