200902116 九、發明說明 【發明所屬之技術領域】 本發明，是關於裝著於臉部的口罩。 【先前技術】 以往，在口罩戴用者的口部周圍形成空間的口罩本體 部’是於口罩戴用時成爲立體狀的口罩（被稱之爲「立體 口罩」），例如，專利文獻1所揭示者。當戴用此口罩時 ’由於在口罩本體部與口罩戴用者的口部之間形成有空間 (口部空間），所以可以消除難以呼吸等之不舒服感。此 種口罩，一般是被使用在對抗花粉或是對抗感冒，近年， 正檢討爲了要給口罩戴用者作出一個舒適有益的環境。例 如，正硏究檢討將芳香成分等之揮發成分供給於口罩本體 部與口罩戴用者的口部之間所形成的空間。因此，要求對 口罩戴用者之口部空間供給揮發成分等的有效技術。 〔專利文獻1〕 日本特開平7-275384號公報 【發明內容】 〔發明所要解決之問題〕 本發明，其目的係在於提供一種針對於口罩戴用時， 具備有於口罩戴用者之口部以形成空間（口部空間）之方 式所構成之口罩本體部的口罩，對口部空間供給揮發成分 等的有效技術。 -5- 200902116 〔發明解決問題之技術手段〕 本發明之第一發明，是關於具備口罩本體部、左右一 對的掛耳部、以及被安裝構件的口罩。口罩，也可以是被 設定爲一次性使用至複數次使用的用後即棄型形態者。或 者是，藉由進行洗滌而能夠重覆使用之形態者亦可。 口罩本體部，係至少覆蓋口罩戴用者之口及鼻。口罩 本體部，是由不織布所構成之薄片所形成，並於口罩戴用 時以成爲立體狀之方式所構成。藉由口罩本體部成爲立體 狀，於口罩戴用者之口部周圍（口罩本體部與口罩戴用者 的口部之間）形成空間（口部空間）。口罩本體部，可以 由1薄片或是複數片薄片所形成。例如，是藉由局部性地 接合1薄片所形成。或是，藉由接合複數片薄片的全部或 是一部分所形成。該口罩本體部，只要至少於口罩戴用時 會成爲立體狀即可。例如，也可以是在口罩戴用時（口罩 使用時）就成爲立體狀，於口罩未戴用時（口罩未使用時 )折疊成平面狀。或是，不僅在口罩戴用時，於口罩未戴 用時亦成爲立體狀亦可。形成口罩本體部之薄片，是由機 械性、化學性、熱性等之處理讓纖維固定或相交絡所製作 之薄片狀的構成物。於典型上，是藉由包含一部分熱熔融 性纖維（熱可塑性纖維）而能夠融著（熔著）的不織布所 構成。一對掛耳部，是分別從口罩本體部的右側及左側延 伸，再拉掛於口罩戴用者的耳朵。 被安裝構件，係具有透氣性不同的複數片薄片，此等 -6 - 200902116 複數片薄片’是以透氣性最低的薄片被配置於一方側之方 式重疊著’並且，被安裝構件，係在其一方側的面（透氣 性最低之薄片的面）被配置於與口罩戴用者相反側之狀態 下’被安裝於口罩本體部的戴用面側。被安裝構件，爲預 先被安裝於口罩本體部之戴用面側亦可；或是，於口罩戴 用時’再安裝於口罩本體部的戴用面側亦可。「安裝於口 罩本體的戴用面側」在形態上，係包含：藉由接著帶或是 黏扣帶等之接著力將被安裝構件貼著在口罩本體部之戴用 面側的形態、或是將構成口罩本體部之薄片作成雙重構造 ’將被安裝構件插入於薄片之間的形態等。又，對於「貼 著於口罩本體部的戴用面側」在形態上，是包含：貼著於 口罩本體部或是掛耳部之戴用面（口罩戴用者側的面）的 形態。 又，被安裝構件，只要其一方側的面（透氣性最低的 薄片）配置在口罩戴用者的相反面側即可，而薄片數目可 以適當地選擇。又，作爲將被安裝構件安裝於口罩本體部 之戴用面的手法可以使用適當的手法。又，被安裝構件， 可以是固定於口罩本體部的戴用面，也可以是能夠裝卸地 安裝。「被安裝構件之一方側的面被配置於口罩戴用者的 相反側」之形態，例如，被安裝構件貼著於口罩本體部之 戴用面之情形時’其一方側的面爲配置於口罩本體部的戴 用面側。 於本發明之口罩，將揮發性物質配置於比構成被安裝 構件之薄片當中透氣性最低的薄片還靠近口罩戴用者側之 200902116 情形時，藉由透氣性最低之薄片’抑制來自揮發性物質所 產生之揮發成分排出到口罩本體部之戴用面相反側（口罩 戴用者相反側）。作爲配置揮發性物質之方法，例如，可 以使用：讓配置在比透氣性最低之薄片還要靠近口罩戴用 者側的薄片含有揮發性物質之方法等。藉此，於口罩本體 部與口罩戴用者之口部之間所形成的空間（口部空間）內 ，成爲含有揮發成分等之有益環境。 在其他形態之口罩，被安裝構件係形成爲帶狀。並且 ，被安裝構件，於口罩戴用時以延伸於口罩戴用者之左右 方向之方式被安裝於口罩本體部的戴用面側。被安裝構件 的安裝處，爲了防止妨礙到口部呼吸，故以除了口部正面 之處所以外，特別是，比口部更上側之處爲佳。再者，爲 了防止鼻子呼吸受到妨礙，故以比鼻尖（鼻孔）還上側之 處爲更佳。藉由如此之構成，可以形成良好的口部空間。 再者在其他形態之口罩，是於口罩本體部的戴用面側 及被安裝構件之一方側之面之至少一方設有接著體。並且 ，藉由該接著體的接著力，使被安裝構件被安裝於口罩本 體部的戴用面側。作爲接著體者，例如，使用具備接著劑 或黏著劑之接著體，具有構成黏扣帶之插入部或被插入部 之接著體。又，可以是當地選擇將接著體設於口罩本體部 之戴用面側及被安裝構件之一方側之面的兩方之構成，或 是設於其中任一方之構成。「將接著體設於口罩本體部之 戴用面側」之形態上，亦包含設於口罩本體或掛耳部之口 罩戴用者相反側之面的形態。藉由如此之構成，可以容易 -8- 200902116 地將被安裝構件安裝於口罩本體部的戴用面側。 再者在其他形態之口罩，接著體，是使被安裝構件裝 卸自如地安裝於口罩本體部的戴用面側。例如，接著體的 接著力，是以高於將被安裝構件保持在安裝於口罩本體部 之戴用面側的狀態所必須之保持力以上，並低於用以將被 安裝構件卸下之特定力以下之方式來設定。藉由如此之構 成，可以反覆使用被安裝構件。 再者在其他形態之口罩，接著體，至少設置於被安裝 構件之至少2處。此2處，是設定於被安裝構件之長邊方 向的兩端部。在本發明中，例如，具有接著劑或黏著劑之 接著體設於被安裝構件。將接著體僅設在被安裝構件之情 形時，由於可以將被安裝構件，貼著於口罩本體部之戴用 面側的任意位置，所以可以容易地變更被安裝構件的安裝 位置。 再者在其他形態之口罩，接著體，係設置於口罩本體 部之戴用面側的至少2處。此2處，是以在口罩戴用時配 置在口罩戴用者之左右之方式來設定。在本發明中，例如 ，具有接著劑或黏著劑之接著體設於口罩本體部的戴用面 側，藉由如此之構成，可以容易地辨別被安裝構件的安裝 位置。 再者在其他形態之口罩，設有接著體之2處，是以於 口罩戴用時朝口罩戴用者之上下方向偏離之方式來設定。 藉由如此之構成，口罩本體部或被安裝構件，特別是口罩 本體部於折疊時，可以防止設於左右的接著體彼此相互接 -9- 200902116 著。 再者其他形態之口罩，作爲設於口罩本體部之戴用面 側的接著體以及設於被安裝構件之一方側之面之接著體當 中之一方的接著體，是使用具有構成黏扣帶之插入部及被 插入部當中之一方的接著體，作爲另一方的接著體，是使 用具有構成黏扣帶之插入部及被插入部當中之另一方的接 著體。一般而言，插入部是由鉤所構成，被插入部是由環 所構成。藉由如此之構成，可以容易地將被安裝構件安裝 於口罩本體部的戴用面側。又，藉由調整黏扣帶之接著力 ，可以裝卸自如地將被安裝構件安裝於口罩本體部的戴用 面側。 再者在其他形態之口罩，作爲設於被安裝構件之一方 側之面的接著體，是使用構成黏扣帶的插入部。並且，作 爲構成黏扣帶的被插入部，是使用藉由口罩本體部或是掛 耳部的纖維所構成的插入部。藉由如此之構成，由於不必 再另行設置構成黏扣帶的被插入部，所以可以使構成簡單 化。 再者在其他形態之口罩，被安裝構件，係具備有折疊 線，在該折疊線之處折疊著。藉此，被安裝構件，成爲以 折疊線作爲突出前端的凸形狀。此凸形狀係卡合於口罩本 體部之戴用面側的凹窪。藉由如此之構成，可以容易地將 被安裝構件定位於口罩本體部的戴用面。又，藉由將折疊 線形成於被安裝構件之長邊方向（左右方向）的中央，可 以將接著體僅設於被安裝構件之長邊方向（左右方向）兩 -10- 200902116 側的端部。 本發明之第二發明，是關於口罩用被安裝構件。本發 明之口罩用被安裝構件，係具備覆蓋口罩戴用者之口及鼻 的口罩本體部、及左右一對的掛耳部，且至少於口罩戴用 時被安裝於口罩本體部成爲立體狀的口罩（立體口罩）上 。口罩用被安裝構件，爲具有透氣性不同的複數片薄片體 。該複數片薄片’是以透氣性最低之薄片被配置於一方側 之方式而重疊著。並且，口罩用被安裝構件，是使其一方 側之面（透氣性最低的薄片）被配置在與口罩戴用者相反 側的狀態下來安裝於口罩本體部的戴用面側。將口罩用被 安裝構件安裝於與口罩戴用者相反側的構成，對於口罩用 被安裝構件之構成爲如前所述者。 藉由如此之構成，可以抑制口部空間內之揮發成分等 排出至口罩本體部之戴用相反面側。因此，可以將口部空 間內創造出適合於口罩戴用者之環境。 再者在其他形態之口罩用被安裝構件，是於一方面側 之面設置接著體。並且，藉由該接著體的接著力，使口罩 用安裝構件貼著於口罩本體部的戴用面側。藉由如此之構 成，可以容易地將口罩用被安裝構件安裝於口罩本體部的 戴用面側。 再者在其他形態之口罩用被安裝構件’是形成爲帶狀 。並且，接著體，是設於長邊方向的兩端部。在本形態中 ，例如，將具有接著劑或黏著劑之接著體設於口罩用被安 裝構件。藉由如此之構成’可以容易地變更口罩用被安裝 -11 - 200902116 構件對口罩本體部之戴用面側的安裝位置。 再者在其他形態之口罩用被安裝構件，爲具有折疊線 ，在該折疊線之處折疊。藉此，口罩用被安裝構件，成爲 以折疊線作爲突出前端的凸形狀。此凸形係卡合於狀口罩 本體部之戴用面側的凹窪。藉由如此之構成，可以容易地 將口罩用被安裝構件定位於口罩本體部的戴用面側。又， 藉由使折疊線形成在被安裝構件之長邊方向（左右方向） 的中央，可以僅在口罩用被安裝構件之長邊方向（左右方 向）兩側的端部設置接著體。 〔發明效果〕 如上所述般，在本發明中，針對於至少在口罩戴用時 於口罩戴用者的口部周圍形成空間（口部空問）之口罩， 可以使口部空間內保持含有揮發成分等之適宜環境。又， 對於至少在口罩戴用時於口罩戴用者之口部周圍形成空間 (口部空間）之口罩，可以取得用以使口部空間內保持含 有揮發成分等之適宜環境的口罩用被安裝構件。 【實施方式】 於以下，參照第1圖〜第6圖詳細說明本發明之口罩 之一實施例的構成。本實施例之口罩1，是由預設可使用 1次至數次之用後即棄型口罩所構成。又，本實施例之口 罩1，不僅具備防止花粉或防止病毒（例如，感冒病毒） 之阻絕功能，並可以使用來作爲具有調整包含口部或鼻腔 -12- 200902116 空間內之環境的環境調整功能的口罩。 本實施例之口罩1的整體構成，是顯示於第1圖及第 2圖。於第1圖，是顯示口罩1的立體圖；於第2圖，是 顯示從口罩戴用者側（內側）所觀察之將口罩1擴開後之 狀態（「口罩戴用狀態」或「口罩使用狀態」）的圖面。 如第1圖及第2圖所示，本實施例之口罩1，是由覆 蓋口罩戴用者之口及鼻的口罩本體部2、掛耳部3、以及 被安裝構件（被貼著構件）1 〇所構成。被安裝構件1 0， 爲對應於本發明之「口罩用被安裝構件」。 (口罩本體部2) 口罩本體部2，係具有覆蓋口罩戴用者之右顏面的右 側薄片2a及覆蓋左顏面的左側薄片2b。右側薄片2a與 左側薄片2b，是藉由熱熔著而接合。於右側薄片2a與左 側薄片2b的接合部分，形成有延伸於上下方向的接合緣 2c。藉此，口罩本體部2，以接合緣2c爲交界二分爲左 右。右側薄片2a與左側薄片2b之形狀及接合處，於口罩 非戴用時（口罩未使用時〉，是以右側薄片2a與左側薄 片2b成相互抵接之折疊狀態（平面狀）之方式而設定。 又，如第1圖及第2圖所示，於右側薄片2a與左側薄片 2b爲開離之口罩戴用時（口罩使用時），是以於口罩本 體部2之戴用面（背面）2d側形成凹狀空間（凹窪4 )之 立體狀之方式而設定。亦即，本實施例之口罩1，是作爲 立體口罩而構成。又，口罩本體部2，只要至少於口罩戴 -13- 200902116 用時以成爲立體狀之方式來構成即可’以口罩戴用時（口 罩使用時）及口罩非戴用時（口罩非使用時）皆成爲立體 狀之方式來構成亦可。 右側薄片2a與左側薄片2b，乃對應於本發明之「構 成口罩本體部的複數個薄片」。 於本實施例中，口罩本體部2，亦即右側薄片2a與 左側薄片2b，是由熱可塑性合成纖維之不織布所形成。 作爲熱可塑性纖維者，可使用聚乙烯、聚丙烯、聚對苯二 甲酸乙酯等，利用氣流法、紡黏法、熱熔法、水針法、點 黏法、熔吹法、縫編法、化學非織物熱熔法、針刺法等所 製造，可以適切地使用基重（密度）30〜150g/m2者。作 爲口罩本體部2之不織布者，可使用具有透氣性，肌膚觸 感良好者。又，於口罩戴用時，爲使口罩本體部2易於保 持於立體狀，以使用伸縮性較掛耳部3還低者爲佳。 (掛耳部3) 掛耳部3，是分別從口罩本體部2的右側及左側，也 就是從右側薄片2a及左側薄片2b各別之端部延伸。各掛 耳部3，是由不同於口罩本體部2之個體所形成’局部性 疊合地接合於口罩本體部2。又，各掛耳部3’亦可與口 罩本體部2 —體地形成。 又，各掛耳部3，形成爲具有開口 3 a之環狀。於口 罩戴用時，口罩戴用者之臉面，特別是在，藉由口罩本體 部2將鼻及口予以被覆之狀態下，掛耳部3之開口 3 a爲 -14- 200902116 掛套於口罩戴用者的耳朵。掛耳部3，是與口罩本體部2 同樣地’由熱可塑性合成纖維之不織布所形成。又，爲了 不對耳朵造成痛楚，以使用具有伸縮性之材料來形成者爲 佳。例如，可以適宜地採用：由能夠非彈性地伸長之伸長 性纖維所形成的伸長層（例如’聚丙烯連續纖維相互熔著 成的不織布）’與由能夠彈性伸縮之彈性伸縮性纖維所形 成的彈性層（例如’使用由熱可塑性合成纖維之彈性體或 氨基甲酸乙酯等所形成之彈性線的不織布）所相互積層之 構成。 (被安裝構件1 0 ) 在本實施例中，被安裝構件（被貼著構件）10，是形 成爲帶狀（「膠帶狀」或「板狀」）之薄片。被安裝構件 10，是被安裝在口罩本體部2之戴用面2d側，使長邊方 向（長邊方向）成爲左右方向（於口罩戴用時之口罩戴用 者的左右方向）地安裝。特別是，被安裝構件10，於口 罩本體部2之戴用面2d側之預定的安裝區域（被貼著區 域）B，爲能夠裝卸地安裝。亦即，成爲可以選擇：被安 裝構件1 0已安裝於戴用面2d側之安裝區域B的狀態（於 第1圖以虛線所顯示之狀態或是於第2圖以實線所顯示之 狀態），和被安裝構件1 〇已從戴用面2d側之安裝區域B 取下的狀態（於第1圖以兩點鎖線所顯示之狀態）。又， 被安裝構件10’爲預先安裝於口罩本體部2之戴用面2d 側的安裝區域B亦可。或是，被安裝構件1〇，於口罩戴 -15- 200902116 用時’再安裝於口罩本體部2之戴用面2d側的安裝區域 B亦可。「安裝於口罩本體2的戴用面2d側」在形態上 ’係包含：藉由接著帶或是黏扣帶等之接著力將被安裝構 件1 0貼著在口罩本體部2之戴用面2d側的形態、或是將 構成□罩本體部2之薄片作成雙重構造，將被安裝構件 1 〇插入於薄片之間的形態等。對於「貼著於口罩本體部2 的戴用面2d側」在形態上，是包含：貼著於口罩本體部 2或是掛耳部3之戴用面（口罩戴用者側的面）的形態。 被安裝構件10之具體性構造，顯示於第3圖及第4 圖。於第3圖是顯示被安裝構件1〇的立體圖，於第4圖 是顯示第1圖之A - A線的斷面構造。 如第3圖及第4圖所示，被安裝構件10，是使第1 薄片12與第2薄片13相疊合地接合於樹脂製（例如，聚 乙烯製）的薄膜薄片11，而形成爲長方形的薄片。薄膜 薄片11’是由透氣性比第1薄片12及第2薄片13更低 的薄膜材料來形成爲薄片狀形。第1薄片12，爲含有預 定的揮發性物質等，而形成爲薄片狀。第1薄片12，是 被包夾於薄膜薄片11與第2薄片13之間。第1薄片12 ’可以含有揮發性物質等，只要能夠將來自於揮發性物質 等所產生的揮發成分是釋放出即可。例如，可以使用不織 布來形成。或是，也可以使用凝膠狀物質來形成。第2薄 片13，只要使第1薄片所含有的揮發性物質等所產生的 揮發成分能夠透過即可。例如，第2薄片1 3，可以使用 與第1薄片12同樣的不織布來形成。藉由此之第2薄片 -16- 200902116 13，防止含有揮發物質等之第1薄片12直接接觸於口罩 戴用者的臉部。 薄膜薄片11、第1薄片12、及第2薄片13,是對應 於本發明之「透氣性不同的複數片薄片」；薄膜薄片11 ，是對應於本發明之「透氣性最低的薄片」：被安裝構件 10，是對應於本發明之「具備有透氣性不同的複數片薄片 ’複數片薄片，是使透氣性最低的薄片以配置於一方側之 方式而重疊的被安裝構件」。 被安裝構件1 〇，是形成爲例如，具有其縱向方向（ 正交於長邊方向之方向）的長度dl爲1〇〜40mm，橫向 方向（長邊方向）的長度d2爲100〜150mm之長方形的 薄片（帶狀體）。又’詳細如後所述，在此爲了確保吾人 對口罩本體部2之所期望的透氣性，故使被安裝構件i 〇 之面積（dlxd2 )相對於口罩本體部2 (戴用面2d)之面 積的比率（面積比率）以在預定範圍內之方式，來形成被 安裝構件10爲佳。被安裝構件10，其面積比率只要是滿 足該預定範圍內之面積比率的形狀，可以形成爲長方形以 外的形狀’例如，正方形、圓形、橢圓形、多角形等之形 狀。 又，被安裝構件10，於長邊方向（左右方向）的中 央位置（包含大致中央位置），具備有延伸於與長邊方向 垂直相交（包含大致垂直相交）之方向（上下方向）的折 疊線L。並且’被安裝構件10,是在該折疊線L之處被 折疊。 -17- 200902116 於口罩收納時或是口罩非戴用時（口罩未使用時）， 被安裝構件1 0 ’於折疊方向施加有力量。藉此，如第3 圖之「折疊時」，折疊線L之右側的部分與左側的部分相 疊合。此時，口罩本體部2亦在接合緣2c處被折疊。 另一方面，將被安裝構件10安裝於口罩本體部2之 情形時，除去朝向折疊方向的力。藉此，如第3圖之「安 裝時」，是以折疊線L爲支點而擴開。亦即，藉由除去朝 向折疊方向的力，使折疊線L之右側的部分與左側的部分 開離。此時，被安裝構件1 〇，成爲以折疊線L作爲突出 前端的凸形狀。該凸形狀由於卡合於戴用面2d側之凹窪 4，故可以容易地將被安裝構件10定位於口罩本體部2。 又，藉由該凸形狀與戴用面2d側的凹窪4卡合，可以將 用以使被安裝構件10貼著於口罩本體部2之戴用面2d的 接著體1 0 a (詳細後述之），僅設於被安裝構件1 〇之長 邊方向（左右方向）兩端部。於被安裝構件1 0之折疊線 L處所形成的凸形狀，是對應於卡合於口罩本體部2之戴 用面2d側之凹窪4的「卡合部」。 於第5圖，是顯不被安裝構件1〇〇之另一實施例的立 體圖。於第5圖所示的被安裝構件10，折疊線L之右側 的部分與左側的部分，是在折疊線L的附近相互接合。於 第5圖中，折疊線L之右側的部分與左側的部分，是沿著 沿折疊線L的接合部1 4接合成線狀。於第5圖所示的被 安裝構件1 〇中，由於形成接合部1 4的部分變得較硬，所 以突出前端部分（折疊線L與接合部1 4之間的部分）變 -18- 200902116 得較硬。因此’將以折疊線L作爲突出前端之前端部分定 位於戴用面2d側之凹窪4的定位作業變得較爲容易，而 可以容易地將被安裝構件1〇定位於口罩本體部的戴用面 2d側。 又，於本實施例之被安裝構件1 0，係於薄膜薄片11 之左右方向的兩端部設有接著體10a。該接著體10a，是 用以將被安裝構件1〇’貼著於口罩本體部2之戴用面2d 側的安裝區域B。藉由使用接著體i〇a，可使將被安裝構 件1〇安裝於口罩本體部之作業變得簡單。例如，在將被 安裝構件插入於構成口罩本體部的不織布間之時，由於不 會如先行技術般地使被安裝構件與構成口罩本體部之不織 布造成干涉。因此，提升被安裝構件對口罩本體部之安裝 作業性。 (第1接著構造） 在第1接著構造中，係使用的接著劑帶或是黏著劑帶 來作爲接著體10a。作爲接著劑帶或是黏著劑帶者，與不 織布之間可以使用具有特定接著力之習知所構成的帶。此 時’是將接著劑帶或黏著劑帶與不織布之間的接著力，以 高於讓被安裝構件10保持在接著於口罩本體部2之狀態 所必須之保持力以上，並低於用以將被安裝構件1 〇從口 罩本體部2卸下之特定力以下之方式來設定爲佳。藉由將 接著力如此地設定，由於可以將被安裝構件丨〇貼著於口 罩本體部2的戴用面2d側或是從口罩本體部2的戴用面 -19- 200902116 2 d側取下，所以被安裝構件1 〇可以重複地使用。 又，接著劑帶或黏著劑帶，可以設在被安裝構件1 〇 的薄膜薄片11及口罩本體部2的戴用面2d側之至少一方 。當然，也可以兩方都設置。對於「將接著體10a設置在 口罩本體部2之戴用面2d側」之形態上，亦包含將接著 體l〇a，設置在口罩本體部2或是掛耳部3的戴用面（口 罩戴用者側之面）之形態。又，在第1接著構造中，配置 左右（口罩戴用者之左右）兩端部之接著體10a之處所， 係以朝上下方向（口罩戴用者的上下方向）偏離之方式來 設定爲佳。藉由如此配置接著體1 〇a，口罩本體部2於折 疊時，可以防止配置在口罩本體部2之戴用面2d左右兩 端部處的接著體1 〇a彼此相互接著。又，於被安裝構件 10的戴用面2d側與口罩本體部2的薄膜薄片11其兩方 都設置接著體l〇a之情形時，是將被安裝構件1〇之薄膜 薄片11之長邊方向（左右方向）兩端部的接著體l〇a， 只有：對應於口罩本體部2之戴用面2d側之長邊方向（ 左右方向）兩端部的接著體l〇a之上下方向之偏移量的偏 移量，來使其朝上下方向偏離配置。 (第2接著構造） 在第2接著構造中，使用接著體l〇a來構成黏扣帶。 作爲黏扣帶者，可以使用周知之構成的黏扣帶。黏扣帶’ 是藉由設置於一方側之構件的插入部，以及設在另一方側 之構件的被插入部所構成。例如’插入部，係具有小磨薛 -20- 200902116 型的鉤（或’鎖鑰型的鉤）’被插入部，係具有環。當將 一方之構件與另一方之構件貼合時，藉由插入部的鉤鉤卡 (纏繞）於被插入部的環使兩者貼著。又，當將一方之構 件與另一方之構件朝相反方向拉開時，藉由插入部的鉤從 被插入部的環拔開使兩者開離。藉由將此黏扣帶的接著力 ，以高於讓被安裝構件10保持在貼著於口罩本體部2之 狀態所必須之保持力以上，並低於用以將被安裝構件i 〇 從口罩本體部2卸下之特定力以下之方式來設定，使被安 裝構件10成爲能夠裝卸於口罩本體部2之戴用面2d側的 安裝區域B。 在第2接著構造中，於被安裝構件10之薄膜薄片n 或口罩本體部2之戴用面2d側之一方，配置具有插入部 的接著體20a ’於另一方配置具有被插入部的接著體1〇a 〇 又，在第2接著構造中，可以於被安裝構件1〇的薄 膜薄片11，配置具有插入部的接著體l〇a，於口罩本體部 2的戴用面2d或是掛耳部3，配置具有被插入部的構件。 或是，於被安裝構件10的薄膜薄片11，配置具有插 入部的接著體1 0a，也可以將形成口罩本體部2或掛耳部 3的不織布本身的纖維作爲被插入部來使用。將不織布本 身的纖維作爲被插入部來使用時，由於被插入部部必另外 再安裝，所以可以將構成簡約化。藉由伸縮性比形成口罩 本體部2之不織布還高之較粗不織布來形成掛耳部3之情 形時，以形成掛耳部3的不織布作爲黏扣帶之被插入部來 -21 - 200902116 使用爲佳。 從側面觀察口罩戴用者在戴用本實施例之口罩1的狀 態之圖面係如第6圖所示。如第6圖所示，於口罩戴用時 口罩本體部2成爲立體狀之口罩（立體口罩），於口罩戴 用者之口部周圍（口罩本體部2與口罩戴用者的口部之間 )形成有空間（口部空間）5。藉由該空間5，可以消除 呼吸不易等之不舒適感。 再者，藉由將含有揮發性物質等之被安裝構件10安 裝於口罩本體部2的戴用面2d，使從揮發性物質等所產 生的揮發成分釋放至空間5內。藉此，於口部周圍的空間 5內，可以製造出對口罩戴用者有益的環境。 此時，安裝被安裝構件1 〇的安裝區域B，較佳是爲 了防止會妨礙到口呼吸，因此除了口部正面之區域，例如 ，選擇出比口部更上方的區域（於第6圖以虛線所顯示的 位置）。更佳爲，爲了防止會妨礙到鼻呼吸妨，因此選擇 比鼻尖（鼻孔）更上方的區域（於第6圖以兩點鎖線所顯 示的位置）。將被安裝構件1 〇安裝於比鼻尖（鼻孔）還 要靠近上方的區域時，釋放至空間5內的揮發成分等，從 口罩戴用者的鼻尖朝向上方移動是受到被安裝構件10所 阻止。藉此，由於揮發成分等被滯留於形成在比鼻尖還要 下方的口罩本體部2與口罩戴用者的口部之間的空間（口 部空間）5內，所以可以給口罩戴用者長時間維持有效用 的環境。 又，若當被安裝構件1 0之面積（戴用面2d側的面積 -22- 200902116 )相對於口罩本體部2的面積（戴用面2d的面積）的比 率（面積比率）太大時，則口罩本體部2的透氣性會降低 。此時，恐怕口罩戴用者會感到不易呼吸。 在此，本發明者們，爲了設定出良好的口罩本體部2 之透氣性，因此針對於較佳的面積比率進行檢討。具體上 ，是設定出口罩戴用者難以感到不易呼吸之口罩內壓力的 範圍。並且，測定：使被安裝構件的面積，亦即被安裝構 件1 〇之面積相對於口罩本體部2之面積的比率（面積比 率）變化時的口罩內壓力。藉此，能夠判別較佳的面積比 率。 於第7圖及第8圖，是模式性地顯示測定口罩內壓力 之狀態。 首先，如第7圖所示，先設定測量機器。作爲測量機 器者，是使用配置在口罩內的壓力檢測管（例如， MISUMI公司製的 SPLS2-I〇〇〇0 2x(/>1)、壓力檢測軟管 (例如，SMC公司製的 TH0425BU-20)、壓力檢測轉換 器（例如，Aivision公司製的0580D型）、資料記錄器（ 例如，ROHRM理硏公司製的Lab-Pico-Q2型）、PC (個 人電腦）。其次，在口罩戴用者所戴用著的口罩上開孔， 將壓力檢測管穿通開孔。然後，將壓力檢測管的前端，以 與鼻氣息垂直之方式配置於口罩戴用者之鼻下lcm之位 置（請參照第8圖）。被安裝構件1 0，以安裝（被覆附 著）在比口罩戴用者之口部更上方的區域爲佳。其次，以 p c設定好資料收集方法之後，按壓資料記錄器的開始按 -23- 200902116 鈕開始測量。藉此，將口罩內壓力的資料記錄至pc。測 量開始後，在經過了規定的測量時間（例如，1 〇〇秒）之 時點後結束測量。從記錄於PC之資料，計算出口罩戴用 者吐氣時之壓力峰値的平均値、口罩戴用者吸氣時之壓力 峰値的平均値。 如以上般地實施，在測量後之口罩戴用時之口罩內壓 力如第9圖及第10圖所示。於第9圖，是顯示使用透氣 性（140cc/cm2 · sec )之口罩本體部2之情形時的測量結

超出（±0.6mmaq )的範圍。 如第9圖所示地，使用透氣性（140cc/cm2· sec)之 口罩本體部2之情形時，爲了確保所期望的透氣性以實施 例1〜3爲佳。因此，藉由將面積比率設定在10〜60%的 範圍內可以確保所期望的透氣性。 又，如第10圖所示地，使用透氣性（200cc/cm2 · s e c )之口罩本體部2之情形時，爲了確保所期望的透氣 性以實施例1〜4爲佳。因此，藉由將面積比率設定在1 0 〜75 %的範圍內可以確保所期望的透氣性。 -24- 200902116 又，關於面積比率的下限値，被安裝構件10所含有 的揮發性物質等對於口罩戴用者可以賦予之最低限度之效 果的範圍內，以因應揮發性物質等之特性等來進行適當設 定爲佳。又’作爲口罩本體部2’爲了確保一定的阻絕特 性，以使用透氣性（200cc/cm2 · sec )以下者爲佳。 又，被安裝構件1 〇之剛性較低之情形時，會容易產 生被安裝構件1 〇的彎曲、撓彎、縐褶等，恐怕將被安裝 構件10安裝於口罩本體部2之戴用面2d側之安裝區域B 的作業會有困難。在此，本發明者們，對於被安裝構件 1 〇之安裝作業性良好的被安裝構件1 0之較佳的硬挺度進 行了檢討。 被安裝構件1 〇之硬挺度（硬度、柔軟性）之測量結 果顯示於第1 1圖。於第11圖，是顯示定性評估出以懸臂 法（JIS L 1 096 )測量使用硬挺度不同之被安裝構件1〇時 其安裝作業性之結果。從第1 1圖之測量結果，爲了易於 進行安裝被安裝構件20之作業（例如，貼著作業），將 被安裝構件10之長邊方向的硬挺度設定爲l〇〇mm以上爲 佳。又’第1 1圖中之PE、PP、PET，分別表示聚乙烯、 聚丙烯、聚對苯二甲酸乙酯。 如以上所述，在本實施例中，是將含有揮發性物質等 之第1薄片12配置在：比構成被安裝構件1〇之薄片當中 之透氣性最低的薄膜薄片1 1更靠近口罩戴用者側。藉此 ’可以抑制從揮發性物質等所產生的揮發成分釋放於口罩 本體部2之戴用面相反側。因此，口部空間5內可以成爲 -25- 200902116 包含揮發成分等之良好的環境。 特別是，被安裝構件1〇，是形成爲帶狀，其長邊方 向以延伸於口罩戴用者的左右方向之方式，來安裝於口罩

(hanging ear 3) hanging ear 3, It is from the right side and the left side of the mask body 2, respectively. That is, it extends from the respective ends of the right side sheet 2a and the left side sheet 2b. Each ear 3, The mask body portion 2 is joined locally by a portion formed by an individual different from the mask body portion 2. also, Each of the ear straps 3' may also be formed integrally with the mask body portion 2. also, Each ear 3, It is formed into a ring shape having an opening 3a. When the mask is worn, The face of the mask wearer, especially in, The nose and the mouth are covered by the mask body 2, The opening of the ear strap 3 3 a is -14- 200902116 Hanging on the ear of the wearer of the mask. Hanging ears 3, In the same manner as the mask body 2, it is formed of a non-woven fabric of thermoplastic synthetic fibers. also, In order not to cause pain to the ears, It is preferred to use a material that is stretchable. E.g, Can be suitably used: An elongated layer formed of an extensible fiber that can be inelastically elongated (for example, a non-woven fabric in which polypropylene continuous fibers are fused together) and an elastic layer formed of elastically stretchable elastically stretchable fibers (for example, 'used by The elastomer of the thermoplastic synthetic fiber or the non-woven fabric of the elastic threads formed by the urethane or the like is laminated to each other. (mounted member 10) In this embodiment, The mounted member (attached to the member) 10, It is a sheet that is formed into a strip shape ("tape-like" or "plate-like"). Installed component 10, It is attached to the wearing surface 2d side of the mask body 2, The longitudinal direction (longitudinal direction) is attached in the left-right direction (the left-right direction of the wearer wearing the mask when the mask is worn). especially, The component 10 is mounted, a predetermined mounting area (attached to the area) B on the wearing surface 2d side of the mask body 2, For detachable installation. that is, Become an option: The state in which the mounting member 10 is mounted on the mounting area B on the side of the wearing surface 2d (the state shown by the broken line in Fig. 1 or the state shown by the solid line in Fig. 2), And the state in which the mounted member 1 is removed from the mounting area B on the side of the wearing surface 2d (the state shown by the two-point lock line in Fig. 1). also, The member to be attached 10' may be attached to the mounting area B on the wearing surface 2d side of the mask body 2 in advance. Or, Installed component 1〇, When the mask is worn -15-200902116, it is also attached to the mounting area B on the wearing surface 2d side of the mask body 2. "The side of the wearing surface 2d attached to the mask body 2" is in the form of: The attached member 10 is attached to the wearing surface 2d side of the mask body 2 by an adhesive force such as a belt or a fastening tape, Or to form a double structure of the sheets constituting the cover body portion 2, A form in which the member to be mounted 1 is inserted between the sheets, and the like. In the form of "the side of the wearing surface 2d that is attached to the mask body 2", Yes contains: It is attached to the mask main body 2 or the wearing surface of the ear strap 3 (the surface on the wearer side of the mask). The specific construction of the mounted member 10, Shown in Figures 3 and 4. Figure 3 is a perspective view showing the mounted member 1〇, Fig. 4 is a sectional view showing the A-A line of Fig. 1. As shown in Figures 3 and 4, The component 10 is mounted, The first sheet 12 and the second sheet 13 are joined to each other by resin (for example, a film sheet 11 made of polyethylene), It is formed into a rectangular sheet. The film sheet 11' is formed into a sheet shape by a film material having a lower gas permeability than the first sheet 12 and the second sheet 13. First sheet 12, In order to contain predetermined volatile substances, etc. It is formed into a sheet shape. First sheet 12, It is sandwiched between the film sheet 11 and the second sheet 13. The first sheet 12' may contain a volatile substance or the like. It suffices that volatile components derived from volatile substances and the like can be released. E.g, It can be formed using a non-woven fabric. Or, It can also be formed using a gelatinous substance. The second sheet 13, It suffices that the volatile component generated by the volatile matter or the like contained in the first sheet can be transmitted. E.g, Second sheet 1 3, It can be formed using the same nonwoven fabric as the first sheet 12. By the second sheet -16- 200902116 13, The first sheet 12 containing a volatile substance or the like is prevented from directly contacting the face of the wearer of the mask. Film sheet 11, First sheet 12, And the second sheet 13, It is a "multiple sheet having different gas permeability" corresponding to the present invention; Film sheet 11, It is the "lowest permeability sheet" corresponding to the present invention: Installed component 10, It is a plurality of sheets having a plurality of sheets having different gas permeability, corresponding to the present invention. It is an attached member in which the sheet having the lowest gas permeability is superimposed so as to be disposed on one side. Installed component 1 〇, Is formed as, for example, The length dl having its longitudinal direction (the direction orthogonal to the longitudinal direction) is 1 〇 to 40 mm, The length d2 in the transverse direction (longitudinal direction) is a rectangular sheet (band-like body) of 100 to 150 mm. Again, as described later, Here, in order to ensure the desired air permeability of the mask body 2, Therefore, the ratio (area ratio) of the area (dlxd2) of the member to be mounted i 相对 to the area of the mask body 2 (wearing surface 2d) is within a predetermined range. It is preferable to form the member to be mounted 10. The component 10 is mounted, The area ratio is as long as it is a shape that satisfies the area ratio within the predetermined range. It may be formed into a shape other than a rectangle', for example, square, Round, Oval, Polygonal shape, etc. also, The component 10 is mounted, The center position in the long side direction (left and right direction) (including the approximate center position), It has a folding line L extending in a direction (up-and-down direction) perpendicular to the longitudinal direction (including substantially perpendicular intersection). And 'the member 10 is mounted, It is folded at the fold line L. -17- 200902116 When the mask is stored or when the mask is not worn (when the mask is not in use), The mounted member 10' has a force applied in the folding direction. With this, As shown in Figure 3, "Folding," The portion on the right side of the folding line L overlaps the portion on the left side. at this time, The mask body 2 is also folded at the joint edge 2c. on the other hand, When the member to be mounted 10 is attached to the mask body portion 2, Remove the force toward the folding direction. With this, As shown in Figure 3, "When installing," It is expanded by the folding line L as a fulcrum. that is, By removing the force in the direction of folding, The portion on the right side of the folding line L is separated from the portion on the left side. at this time, Installed component 1 〇, It becomes a convex shape with the folding line L as a protruding front end. The convex shape is engaged with the concave portion 4 on the side of the wearing surface 2d. Therefore, the member to be mounted 10 can be easily positioned to the mask body portion 2. also, By engaging the convex shape with the recess 4 on the side of the wearing surface 2d, The following body 10a (described later in detail) for attaching the member 10 to be attached to the mask body 2 can be attached. It is provided only at both ends of the long side direction (left-right direction) of the member to be attached 1 . a convex shape formed at the folding line L of the mounted member 10, It is an "engagement portion" corresponding to the recess 4 that is engaged with the wearing surface 2d side of the mask main body portion 2. In Figure 5, It is a perspective view of another embodiment in which the member 1 is not mounted. The mounted member 10 shown in Fig. 5, The part on the right side of the fold line L and the part on the left side, It is joined to each other in the vicinity of the folding line L. In Figure 5, The part on the right side of the fold line L and the part on the left side, It is joined in a line shape along the joint portion 14 along the folding line L. In the mounted member 1 所示 shown in Fig. 5, Since the portion where the joint portion 14 is formed becomes hard, Therefore, the front end portion (the portion between the folding line L and the joint portion 14) is changed to -18-200902116 to be hard. Therefore, it is easier to position the folding line L as the front end portion of the protruding front end on the side of the wearing surface 2d. On the other hand, the member to be mounted 1 can be easily positioned on the wearing surface 2d side of the mask body. also, The mounted member 10 in this embodiment, Attachments 10a are provided at both end portions of the film sheet 11 in the left-right direction. The body 10a, It is a mounting region B for attaching the member to be attached 1' to the wearing surface 2d side of the mask body 2. By using the junction i〇a, The operation of attaching the member to be mounted 1 to the body portion of the mask can be simplified. E.g, When the member to be mounted is inserted between the nonwoven fabrics constituting the body portion of the mask, Since the mounted member does not interfere with the non-woven fabric constituting the body portion of the mask as in the prior art. therefore, Improve the workability of the mounted member to the mask body. (first following structure) In the first subsequent structure, An adhesive tape or an adhesive tape is used as the adhesive body 10a. As an adhesive tape or adhesive tape, A belt composed of a conventional one having a specific adhesion force can be used with the non-woven fabric. At this time, ' is the adhesion between the adhesive tape or the adhesive tape and the non-woven fabric. It is higher than the holding force necessary for the member to be mounted 10 to be held in the state adjacent to the mask body 2, It is preferably set to be lower than a specific force for removing the member to be attached 1 from the mask body portion 2 or less. By setting the force accordingly, Since the member to be attached can be attached to the wearing surface 2d side of the mask body 2 or from the wearing surface of the mask body 2 to the side of the wearing surface -19-200902116 2 d, Therefore, the mounted member 1 can be used repeatedly. also, Then with a belt or adhesive tape, At least one of the film sheet 11 of the member to be attached 1 and the wearing surface 2d side of the mask body 2 may be provided. of course, It can also be set on both sides. In the form of "the attachment body 10a is provided on the wearing surface 2d side of the mask body 2", Also includes the body l〇a, It is provided in the mask body 2 or the wearing surface of the ear strap 3 (the surface on the wearer side of the mask). also, In the first subsequent construction, Arrange the left and right (the left and right sides of the mask wearer) at the ends of the body 10a at both ends, It is preferable to set the deviation in the up-and-down direction (the upper and lower directions of the wearer of the mask). By configuring the body 1 〇a in this way, When the mask body 2 is folded, It is possible to prevent the adhering bodies 1 〇 a disposed at the left and right end portions of the wearing surface 2d of the mask body 2 from coming back to each other. also, When the wear surface 2d side of the member to be mounted 10 and the film sheet 11 of the mask body portion 2 are provided with the body l〇a, It is a bonding body l〇a at both ends in the longitudinal direction (left-right direction) of the film sheet 11 to be attached to the member to be mounted, only: The amount of deviation of the amount of displacement of the upper and lower sides of the longitudinal direction (left-right direction) of the wearer's surface 2d side of the mask body 2 on the upper and lower directions is To make it deviate from the configuration in the up and down direction. (second following structure) In the second subsequent structure, The adhesive tape is constructed using the adhesive l〇a. As a fastener, A fastening tape of a well-known composition can be used. The fastening tape ′ is an insertion portion of a member provided on one side. And an inserted portion of the member provided on the other side. For example, the 'insert part, A hook (or 'lock key type') inserted with a small mill -20-200902116 type, It has a ring. When one member is attached to the other member, The hooks are hooked (wound) around the inserted portion by the hook of the insertion portion to stick the two. also, When pulling one component and the other component in the opposite direction, The hook of the insertion portion is pulled away from the loop of the inserted portion to separate the two. By the adhesive force of the fastening tape, More than the holding force necessary to hold the member 10 to be attached to the mask body 2, And set lower than a specific force for removing the mounted member i 〇 from the mask body 2, The mounted member 10 is attached to the mounting area B on the wearing surface 2d side of the mask body 2. In the second subsequent construction, On one side of the film sheet n of the member to be mounted 10 or the wearing surface 2d side of the mask body portion 2, The bonding body 20a' having the insertion portion is disposed on the other side, and the bonding body 1a with the inserted portion is disposed, In the second subsequent construction, The film sheet 11 which can be attached to the member 1 to be mounted, Configuring a body l〇a having an insertion portion, The wearing surface 2d of the mask body 2 or the ear strap 3, A member having the inserted portion is configured. Or, On the film sheet 11 of the member 10 to be mounted, Configuring the insulator 10a with the insertion portion, The fiber of the nonwoven fabric itself forming the mask body 2 or the ear strap 3 may be used as the inserted portion. When the fiber of the non-woven fabric is used as the inserted portion, Since the inserted part must be installed separately, Therefore, the composition can be simplified. When the lug portion 3 is formed by a thicker non-woven fabric having a higher stretch than the non-woven fabric forming the mask body portion 2, The non-woven fabric forming the hanging ear portion 3 is used as the inserted portion of the fastening tape - 21 - 200902116 is preferably used. The figure in which the mask wearer wears the mask 1 of the present embodiment as seen from the side is shown in Fig. 6. As shown in Figure 6, When the mask is worn, the mask body 2 is a three-dimensional mask (three-dimensional mask). A space (mouth space) 5 is formed around the mouth of the mask wearer (between the mask body 2 and the mouth of the mask wearer). With this space 5, It can eliminate the uncomfortable feeling of breathing. Furthermore, The mounting member 10 containing a volatile substance or the like is attached to the wearing surface 2d of the mask body 2, The volatile component generated from the volatile matter or the like is released into the space 5. With this, In the space around the mouth 5, An environment that is beneficial to the wearer of the mask can be created. at this time, Install the mounting area B of the mounted component 1 ,, Preferably, to prevent obstruction to mouth breathing, So in addition to the area on the front of the mouth, E.g , Select the area above the mouth (the position shown by the dotted line in Figure 6). Better yet, In order to prevent it from obstructing the nose, So choose the area above the tip of the nose (nostrils) (shown in Figure 6 with the two-point lock line). When the mounted member 1 is mounted on an area closer to the top than the tip of the nose (nostrils), Released to volatile components in space 5, etc. Moving upward from the nose tip of the mask wearer is prevented by the mounted member 10. With this, The volatile component or the like is retained in the space (oral space) 5 formed between the mask body 2 below the tip of the nose and the mouth of the mask wearer. Therefore, the mask wearer can maintain an effective environment for a long time. also, When the ratio (area ratio) of the area of the member to be mounted 10 (the area of the wearing surface 2d side -22 to 200902116) to the area of the mask body 2 (the area of the wearing surface 2d) is too large, Then, the gas permeability of the mask body 2 is lowered. at this time, I am afraid that the wearer of the mask will feel that it is not easy to breathe. here, The inventors, In order to set a good breathability of the mask body 2, Therefore, a review is made for a better area ratio. Specifically, It is a range in which the pressure inside the mask which the outlet cover wearer hardly feels difficult to breathe is set. and, Determination: The area of the component to be mounted, That is, the pressure in the mask when the ratio of the area of the member to be mounted 1 to the area of the mask body 2 (area ratio) is changed. With this, A better area ratio can be discriminated. In Figures 7 and 8, It is a state in which the pressure inside the mask is measured in a pattern. First of all, As shown in Figure 7, Set the measuring machine first. As a measuring machine, Is to use a pressure detecting tube disposed inside the mask (for example, SPLS2-I〇〇〇0 2x (/> manufactured by MISUMI 1), Pressure detection hose (for example, THMC25BU-20) made by SMC, Pressure detection converter (for example, Aivision company's 0580D type), Data logger (for example, ROHRM Technology Co., Ltd. Lab-Pico-Q2 type), PC (personal computer). Secondly, Opening a hole in the mask worn by the wearer of the mask, Pass the pressure detection tube through the opening. then, Put the front end of the pressure detection tube, It is placed at a position lcm below the nose of the mask wearer perpendicular to the nasal breath (please refer to Figure 8). Installed component 10, It is preferable to mount (covering) in an area above the mouth of the wearer of the mask. Secondly, After setting the data collection method with p c, Press the -23- 200902116 button to start the measurement by pressing the data logger. With this, Record the data of the pressure inside the mask to the pc. After the measurement starts, After the specified measurement time (for example, The measurement is ended after 1 o'clock. From the information recorded on the PC, Calculate the average value of the pressure peaks at the exit of the outlet wearer, The pressure of the mask wearer when inhaling. Implemented as above, The pressure inside the mask when the mask is worn after the measurement is as shown in Figs. 9 and 10. In Figure 9, It is a measurement result 1 when the mask body 2 of the gas permeability (140 cc/cm2 · sec) is used. In Figure 10, The measurement result 2 when the mask body 2 of the gas permeability (200 cc/cm2 · sec) is used is shown. also, In the following assessments, It is difficult for the wearer of the mask to feel the range of pressure in the mask that is not easy to breathe, and the range of the pressure inside the mask that the wearer of the mask is likely to feel difficult to breathe. It is set based on statistics. Specifically, It is to set the pressure inside the mask that the mask wearer is difficult to feel difficult to breathe (± 〇. In the range of 6mm aq ), the pressure inside the mask that the mask wearer can easily feel difficult to breathe is set to exceed (±0. 6mmaq) range. When the mask body 2 having a gas permeability (140 cc/cm 2 · sec) is used as shown in Fig. 9, it is preferable to use the first to third embodiments in order to secure desired gas permeability. Therefore, the desired gas permeability can be ensured by setting the area ratio in the range of 10 to 60%. Further, as shown in Fig. 10, in the case of using the mask body 2 having gas permeability (200 cc/cm2 · s e c ), it is preferable to use the first to fourth embodiments in order to secure desired gas permeability. Therefore, the desired gas permeability can be ensured by setting the area ratio in the range of 10 to 75%. -24- 200902116 In addition, the lower limit of the area ratio 値, the volatile substance contained in the member to be attached 10, etc., in the range which can provide the minimum effect to a mask wearer, in response to the characteristics of a volatile substance etc. It is better to make appropriate settings. Further, in order to secure a certain barrier property as the mask body 2', it is preferable to use a gas permeability (200 cc/cm2 · sec) or less. Further, when the rigidity of the member to be attached 1 is low, bending, bending, creases, and the like of the member to be attached 1 are likely to occur, and the wearing member 10 may be attached to the wearing surface 2d of the mask body 2. The operation of the installation area B on the side may be difficult. Here, the inventors of the present invention reviewed the preferable stiffness of the member to be mounted 10 which is excellent in the mounting workability of the member to be mounted. The measurement results of the stiffness (hardness, flexibility) of the member to be mounted 1 are shown in Fig. 11. In Fig. 11, it is shown that the mounting workability when the mounted member 1 having different stiffness is measured by the cantilever method (JIS L 1 096 ) is qualitatively evaluated. From the measurement results of the above-mentioned Fig. 1, it is preferable to set the stiffness of the longitudinal direction of the member to be mounted 10 to l〇〇mm or more in order to facilitate the work of mounting the member 20 to be mounted (e.g., the art). Further, PE, PP, and PET in Fig. 1 show polyethylene, polypropylene, and polyethylene terephthalate, respectively. As described above, in the present embodiment, the first sheet 12 containing a volatile substance or the like is disposed closer to the mask than the film sheet 1 1 having the lowest gas permeability among the sheets constituting the member to be attached 1 Side. Thereby, it is possible to suppress the release of volatile components generated from volatile substances or the like on the opposite side of the wearing surface of the mask body portion 2. Therefore, the mouth space 5 can be a good environment containing a volatile component, such as -25-200902116. In particular, the member to be attached 1b is formed in a strip shape, and the longitudinal direction thereof is attached to the mounting region B on the wearing surface 2d side of the mask body 2 so as to extend in the left-right direction of the mask wearer. Thereby, it is possible to prevent the volatile components and the like in the oral space 5 from being discharged from above the mouth space 5. Therefore, the inside of the mouth space 5 can be a good environment including a volatile component or the like. As described above, in the present embodiment, the adhesion is provided by the attachment member 10 and the body 10a of the mask body portion 2. The member to be attached 1 is attached to the wearing surface 2 d side of the mask body 2 . Thereby, the member to be mounted 10 can be easily attached to the wearing surface 2d side of the mask body 2, and the workability for attaching the mask body 2 to the member 10 to be attached can be improved. Further, in the present embodiment, the first sheet 12 containing a volatile substance or the like is disposed closer to the mask wearer side than the film sheet 11 having the lowest air permeability among the sheets constituting the member to be attached 1 . Thereby, it is possible to suppress the release of volatile components generated from volatile substances or the like on the opposite side of the wearing surface of the mask body 2. Therefore, the inside of the mouth space 5 can be a good environment including a volatile component or the like. In particular, the member to be attached 10 is formed in a belt shape, and its longitudinal direction is attached to the attachment region B on the wearing surface 2d side of the mask body 2 so as to extend in the left-right direction of the mask wearer. Thereby, it is possible to prevent the volatile components and the like in the oral space 5 from being discharged from above the mouth space 5. Therefore, the inside of the mouth space 5 can be a good environment including a volatile component or the like. -26-200902116 Further, in the present embodiment, the attachment body 10a is installed on the wearing surface 2d side of the mask body 2 At least one of the area B and the member to be mounted 1 . Thereby, the member to be attached 10 can be easily attached to the mounting region B on the wearing surface 2d side of the mask body 2 by the adhesion of the body 10a. Further, in the present embodiment, the attachment member 10a can be disposed such that the longitudinal direction thereof is the both end portions of the member to be mounted 1 which are disposed so as to extend in the left-right direction of the mask wearer. In this case, the mounting position of the mounting member 1 to the wearing surface 2d side of the mask body 2 can be easily changed. Further, in the present embodiment, the attachment body 10a can be provided in the attachment region B on the wearing surface 2d side of the mask body portion 2. In this case, by the attachment body 10a provided in the attachment region B, the mounting position of the mounted member 1A can be easily grasped. Further, in the present embodiment, a convex shape of the concave portion 4 that is engaged with the wearing surface 2d of the mask main body portion 2 is formed at the folding line L of the member 1 to be attached. Thereby, the member to be attached 1 can be easily positioned on the wearing surface 2d of the mask body 2. Further, since the folding line L of the member to be attached 1 is positioned by the convex shape, the bonding body 1 〇a can be provided only at both end portions in the longitudinal direction (left-right direction) of the member to be mounted 10. When the adhesive body 10a is provided only at both end portions in the longitudinal direction (left-right direction) of the member 10 to be attached, the wearing member 1 can be easily changed to the wearing surface 2d side of the mask main body portion 2 Installation location. Further, in the present embodiment, as the adhesive body 10a, an adhesive tape or an adhesive tape which is followed by a -27-200902116 or an insertion portion or an inserted portion which constitutes the adhesive tape can be used. In this case, by adjusting the adhesion force from the bonding body 1 〇a and detachably attaching the mounted member 10 to the wearing surface 2d side of the mask body 2, it can be installed repeatedly. Component 10. The present invention is not limited to the embodiments described above, but can be applied in various applications or variations. For example, the above-described embodiment may be modified as follows. In the above embodiment, the first sheet 12 and the second sheet 13 are superposed on the sheet film Π to form the member 10 to be three-layered. However, the sheet having the lowest gas permeability may be disposed on the opposite side of the wearer. On the side, the number of sheets (layer number) constituting the member to be mounted 10 can also be appropriately selected. Further, in the above-described embodiment, the first sheet 12 sandwiched between the sheet film 11 and the second sheet 13 contains a volatile substance or the like, but a volatile substance or the like is disposed on the member to be attached 1 and Not limited to this. For example, it is also possible to use a sheet having a higher gas permeability among two sheets having different gas permeability, 'coating a liquid, a paste, or a gel-like volatile substance, or the like, or in two sheets. A solid or gel-like volatile substance is sandwiched between the two. Further, in the above-described embodiment, the member to be mounted 10 is attached to the wearing surface 2d side of the mask body 2 by using the adhesive force of the bonding body 1 〇a. However, the member 10 to be attached is attached to the mask body. The configuration of the wearing surface 2 d side of the portion 2 is not limited to this. For example, a configuration in which the mask body 2 is formed by a sheet having a two-layer structure and the member to be attached 10 is inserted between the sheets may be employed. Further, in the above embodiment, the mask main body portion 2 is formed by thermally fusing the right side sheet 2a and the left side sheet 2b. However, the number of sheets or the joining method can be appropriately selected. A perspective view of the mask body portion 102 formed using a single sheet is as shown in Fig. 12. The mask body portion 102 shown in Fig. 12 is formed by cutting a piece of the sheet 102a at the upper end portion and joining the cut portions to each other. In the upper end portion of the mask body portion 102, a joint edge l2b extending in the upper and lower directions of the mask wearer is formed in the same manner as the joint edge 2c of the mask body portion 2.
