Description

【０００１】
【発明の属する技術分野】
本発明は花粉、ウィルス、埃等が呼吸に伴って体内に吸引されることを防止するため鼻と口を覆う衛生マスクに関する。
【０００２】
【従来の技術】
この種の衛生マスクの一形式として、鼻の先端高部と唇にマスク生地が局部的に強く密着して息苦しくなるのを防止するため、マスクの内部に金属又はプラスチックの骨材を入れて立体構造にしたものが知られている。
【０００３】
【発明が解決しようとする課題】
従来の衛生マスクは硬い骨材を使って立体構造にしているため、使用時に骨材の当たる違和感が生じ、使い心地が悪い。また、骨材が折れると顔面を傷付けるおそれがある。
本発明はかかる問題点に鑑み、骨材を使わないで、マスク生地が鼻の先端高部や唇等に局部的に強く密着するのを防止できる構造を備えた衛生マスクを提供することを目的とする。
【０００４】
【課題を解決するための手段】
上記目的を達成するため本発明は、略横長矩形の衛生マスクにおいて、衛生マスク本体に略横幅分の長さを有する少なくとも上下２本の横に延びる長いプリーツを形成し、衛生マスク本体の左右両端を裏側に折り重ね、同本体の上端から上側の長いプリーツまでミシン目を入れて縫い着けるとともに、同本体の下端から下側の長いプリーツまでミシン目を入れて縫い着けて前記衛生マスク本体の左右両側に上下両端を開いた袋状の帯部を形成し、該帯部の中間部に略帯部の幅分の長さを有する少なくとも１本の横に延びる短いプリーツを前記上下２本の長いプリーツの間に形成し、前記帯部に耳掛け紐を挿通したことを特徴とする。
【０００５】
【発明の作用・効果】
本発明によれば、衛生マスク本体にその横幅分の長さを有する上下２本の長いプリーツを形成するとともに、本体左右両側の帯部の中間部に短いプリーツを形成し、かつ帯部の上下両側はミシン目で縫い着けるものの、中央部は縫い着けていないので、マスク着用時にマスク本体が船底状の立体構造になる。そのため、マスク生地が鼻や唇に局部的に強く密着するのを防止できる。
しかして、本発明に係る衛生マスクは骨材を用いることなく船底状の立体構造にできるため、安全性が高く、かつ使い心地が良い。
【０００６】
【発明の実施の形態】
以下に本発明を図面に基づき説明するに、図１には本発明の一実施形態に係る衛生マスクの表側が示されている。また、図２には同衛生マスクの裏側が示されている。当該衛生マスク１０は略横長矩形の本体１１と本体１１に内包したフィルター１２と、本体の左右両側に取り付けた耳掛け紐を備えている。
【０００７】
マスク本体１１には略その横幅分の長さを有し、横に延びる長いプリーツ１１ａが上下２本形成されている。また、マスク本体１１の左右両側には上下両端を開いた帯部１１ｂが形成され、帯１１ｂ部に耳掛け紐１３が挿通されている。この帯部１１ｂの中間部には略帯部１１ｂの横幅分の長さを有する短いプリーツ１１ｃが上下２本の長いプリーツ１１ａの間に形成されている。
【０００８】
図３〜図１６に、この衛生マスク１０の製作手順を示す。図３に示すように、所要寸法に裁断した矩形のマスク生地ｍに、フィルター生地ｆを載せる。そして、図４及び図５に示すように、マスク生地ｍを四つ折りに重ねてフィルター生地ｆを包み込む。四つに折り重ねて横長にしたマスク生地ｍを図６及び図７に示すように上下両端を裏側に折ねるようにして三つに折り重ねる。
【０００９】
そして、図８及び図９に示すように、下側の折り重ね部の左右両端を各短い一本のミシン目ｅで縫い着けると共に、上側の折り重ね部の左右両端を各一本の短いミシン目ｅで縫い着ける。四つ折りにしたマスク生地ｍの中央部は図１０に示すように、縫い着けないでおく。
【００１０】
次ぎに、図１１、図１２及び図１３に示すように、四つ折りにしたマスク生地ｍの上下の折り重ね部を短いミシン目ｅから折り返して、上下２本の長いプリーツ１１ａを形成し、マスク本体の左右両端部にロックｇを施す。
【００１１】
続いて、図１４、図１５及び図１６に示すようにマスク本体の中央部の左右両側にタックｈを施し、左右両端から少し内側に縦のミシン目ｋを入れて縫い着ける。
【００１２】
次ぎに、図２に示すようにマスク生地ｍの左右両端を縦のミシン目ｋから裏側に折り重ねる。そして、長いプリーツ１１ａを開いて、上下両端から短いミシン目ｅまで縦に短いミシン目ｎを入れて縫い着ける。こうして、上下両端の開いた帯部１１ｂと、帯部１１ｂの中間に略帯部１１ｂの幅分の長さを有する短いプリーツ１１ｃを形成し、帯部１１ｂに耳掛け紐１３を挿通する。
【００１３】
本実施形態に係る衛生マスクの構造及び製作手順は以上の通りであって、上下２本の長いプリーツ１１ａと左右各１本の短いプリーツ１１ｃを形成したので、マスク１０の着用時にマスク本体１１が船底状の立体構造になり、鼻先や唇に局部的に密着するのを防止できる。
とりわけ本実施形態の衛生マスク１０では帯部１１ｂの上下両側はミシン目ｎで縫い着けるものの、中央部は縫い着けていないことと、帯部１１ｂにタックｈを施して短いプリーツ１１ｃを形成することによりマスク本体１１の左右両端部１１ｄを緩やかに湾曲した形状としたことにより、着用時にマスク本体１１の左右の端部１１ｄが頬に密着し易く、マスク本体１１の左右の端部１１ｄと頬の隙間から花粉等が鼻や口の中に侵入するのを防止できる。
また、図１７〜図１９に示すように上下２本のプリーツ１１ａを必要に応じて延ばすことで、マスク本体１１によって覆われる顔の面積や部位を調整できる。
