有：前後腰圍區域及跨下區域；包含身體側內面及穿衣側 外面之吸液性本體；及形成於前後腰圍區域的側緣部之鉤 要素與環要素。在前腰圍區域的穿衣側外面之其側緣部具 備有環要素，在後腰圍區域的身體側內面之其側緣部具備 有鉤要素，藉由使該溝要素與環要素卡合，能夠形成短褲 ❹形狀。 [專利文獻1]日本特表2002-532147號公報 【發明內容】 [發明所欲解決之課題] 鉤要素及環要素係沿著前後腰圍區域的側緣部，朝縱 方向延伸。藉由將側緣部的長度與鉤要素及環要素的長度 作成大致相同尺寸，增大卡合面積，來將這些側緣部彼此 予以強固地卡合。鉤要素與環要素之卡合係以例如下述方 -4- 200924724 式進行。將飽要素的縱方向上端部與環要素的縱方向 部卡合並疋位’之後’卡合其他部分。但，於在上端 行定位之期間’會有鉤要素及環要素的縱方向下端部 小心地被卡合而彎曲並安裝之情況生。在這樣的情況 須取下不小心而被卡合之部分，在正確的位置重新進 合，手續、時間均會花費之問題產生。此問題特別是 寸大的大人用紙尿褲尤爲顯著。 0 本發明之課題在於提供能容易且確實地進行前腰 域與後腰圍區域之卡合之穿著用物品。 [用以解決課題之手段] 本發明包含第1發明與第2發明。 第1發明係關於，包含具有縱方向及横方向、身 內面及穿衣側外面、前腰圍區域、後腰圍區域、位於 腰圍區域間的跨下區域之吸液性本體；及將與前述前 〇 圍區域的前述横方向相對向且延伸於前述縱方向的側 可相互裝卸地連結之扣合手段的穿著用物品之改良。 第1發明係針對前述穿著用物品，其特徵爲：前 合手段包含有：接合於前述前腰圍區域的前述側緣部 伸於前述縱方向之第1扣合要素；與可裝卸地卡合於 第1扣合要素，並且接合於前述後腰圍區域的前述側

構件所形成’前述彈性構件係在前述第i扣合要素或 第2扣合要素’在朝前述縱方向伸長狀態下被安裝著 作爲理想的其他實施態様之一，具備前述蛇腹構 前述第1扣合要素或前述第2扣合要素係以熱可塑性 所形成’前述蛇腹構造係藉由將前述第〗扣合要素或 φ 第2扣合要素加熱並使其變形來形成。 作爲理想的其他實施態樣之一，前述頂部係藉由 沖壓’使得在前述頂部，作成爲前述第i扣合要素與 第2扣合要素不能卡合。 作爲理想的其他實施態樣之一，具備前述蛇腹構 前述第1扣合要素或前述第2扣合要素，係在與前述 向相對向的上端部或下端部的至少其中一方，具有未 有前述頂部之平坦區域。 〇 作爲理想的其他實施態樣之一，前述第1扣合要 前述第2扣合要素中的一方爲具有多數個鉤之鉤要素 一方爲具有多數個環且可裝卸地卡合於前述鉤要素之 素。 第2發明係關於包含具有縱方向及横方向 '身體 面及穿衣側外面、前腰圍區域、後腰圍區域、位於前 圍區域間的跨下區域之本體；及將與前述前後腰圍區 前述横方向相對向且延伸於前述縱方向的側緣部可相 卸地連結之扣合手段’藉由前述扣合手段，將前述前 彈性 前述 〇 造之 樹脂 前述 加熱 前述 造之 縱方 形成 素及 ，另 環要 側內 後腰 域的 互裝 後腰 -6- 200924724 圍區域連結於周方向之穿著用物品的改良。 第2發明係針對前述穿著用物品，其特徵爲：前述扣 合手段包含有：當進行前述前後腰圍區域的連結時，位於 周方向內側之第1扣合要素；與位於前述周方向外側之第 2扣合要素與’前述第1扣合要素包含有接合於前述側緣 部且延伸於前述縱方向，並且與前述横方向相對向之內外 側緣，前述第2扣合要素係可裝卸地與前述第1扣合要素 0 卡合，包含有接合於前述側緣部且延伸於前述縱方向，並 且與前述横方向相對向之內外側緣，在安裝有前述第2扣 合要素及前述第2扣合要素之前述側緣部的至少其中一方 ，具備有經由折彎區域可將前述第2扣合要素折彎之折彎 誘導手段。 作爲理想的實施態樣之一，前述折彎區域係由前述外 側緣朝前述內側緣延伸，前述折彎區域與對將前述第2扣 合要素的前述橫方向分成二等分之縱中心線的垂線所成之 ® 角度α爲30〜60°。 作爲理想的其他實施態樣之一，前述第2扣合要素係 包含有與前述縱方向相對向且延伸於前述横方向之上下端 緣’前述折彎區域包含有位於前述外側緣之外側端緣部； 與位於前述內側緣之內側端緣部’藉由前述外側端緣部比 起前述內側端緣部更位於前述上端緣側’使得前述折彎區 域傾斜。 作爲理想的其他實施態樣之一’前述折彎誘導手段係 藉由熱加工來形成的 -7- 200924724 作爲理想的其他實施態樣之一’前述折彎誘導手段係 包含形成有縫隙之縫隙部。 作爲理想的其他實施態樣之一 ’前述折彎誘導手段11 包含藉由切除前述第2扣合要素的一部分所形成之分離部 〇 作爲理想的其他實施態樣之一，前述折彎誘導手段包 含安裝於前述第2扣合要素之高剛性構件。 ❹ [發明效果] 若根據第1發明的話，因在第1扣合要素或第2扣合 要素的其中一方，形成有具有朝横方向延伸並朝縱方向分 離複數個頂部之蛇腹構造，所以當蛇腹收縮而重疊時，在 其頂部，第1扣合要素與第2扣合要素卡合。此卡合力小 ’即使這些要素部不小心而卡合，也可容易使其脫離。若 拉引蛇腹使其伸長來將第1扣合要素與第2扣合要素卡合 〇 的話，能以寬廣的面積，強固且正確地卡合。 藉由對頂部進行加熱沖壓，使第1扣合要素與第2扣 合要素不能卡合’能夠容易進行不小心卡合之情況的脫離 〇 因在具有蛇腹構造之第1扣合要素或第2扣合要素， 於縱方向上下端部的其中一方形成不具有頂部之平坦部位 ’所以’能夠先將平坦部位進行卡合並定位後，使蛇腹伸 長來將扣合要素全體予以卡合。 若根據第2發明的話’因在第2扣合要素設有折彎誘 -8- 200924724 導手段，所以，能一邊維持第2扣合要素的折彎狀態，一 邊將第1扣合要素與第2扣合要素之上端緣卡合。將上端 緣卡合後，返回至折彎的下端緣側，卡合第1扣合要素與 第2扣合要素之下端緣。因此’在卡合第1扣合要素與第 2扣合要素之上端緣之期間，能夠防止下端緣不小心卡合 之情況產生。 因折彎區域與對第2扣合要素的縱中心線呈垂直之垂 φ 直線所成的角度α爲30〜60°，沿著此折彎區域將第2扣 合要素折彎，所以，容易折彎第2扣合要素，且容易維持 折彎狀態。 因折彎區域的外側端緣部係藉由位於較內側端緣部更 靠近上端緣側的位置，使折彎區域傾斜，所以，能夠由內 側朝外側折彎第2扣合要素，容易進行在折彎狀態下的第 1扣合要素之卡合。 Q 【實施方式】 <第1發明> 圖1〜5係顯示第1發明之第1實施形態，以大人用 紙尿褲爲例進行說明。如圖1所示，紙尿褲1包含吸液性 本體2與扣合手段3。吸液性本體2具有縱方向Υ、横方 向X及腰圍周圍方向Ζ、和身體側內面4及穿衣側外面5 。吸液性本體2包含有：形成身體側內面4之內面薄片6 、形成穿衣側外面5之外面薄片7、及介裝於這些內外面 薄片6、7之間的吸液性芯材（未圖示）。這樣的吸液性 -9- 200924724 本體2係包含有前腰圍區域8、後腰圍區域9及位於前後 腰圍區域8、9之間的跨下區域1〇。 在前腰圍區域8，形成有與横方向X相對向並延伸於 縱方向Y之前側緣部11’在後腰圍區域9,形成有與横方 向X相對向並延伸於縱方向Y之後側緣部1 2。在前側緣 部11的外面薄片7，藉由接著或熔融來安裝由鉤要素所構 成之第1扣合要素13。 0 在後側緣部12的內面薄片6，藉由接著或熔融，來 安裝可與第1扣合要素13裝卸地卡合之由環要素所構成 的第2扣合要素14。在內面薄片6與第2扣合要素14之 間，延伸於縱方向Y之彈性構件1 5在伸長狀態下被安裝 著。又，第1扣合要素13具有與前側緣部11的縱方向γ 的尺寸大致相同之尺寸。在圖1，第2扣合要素14及後側 緣部12藉由彈性構件15進行收縮，這些構件在其伸長狀 態，縱方向Y的尺寸大致相同，第1扣合要素13與第2 φ 扣合要素14之縱方向Y的尺寸也大致相同。 圖2係圖1的II-II線端面圖。如圖所示，使用4條 之橡膠線作爲彈性構件1 5 ’在寬度方向X以5 m m間隔配 置著。此橡膠線爲聚胺甲酸酯的合成橡膠，但彈性構件j 5 的種類不限於此’亦可使用其他材料。彈性構件15的使 用條數也能以其他材料之關係予以適宜選擇。 如圖1所不’因彈性構件1 5在伸長狀態下被安裝， 當這些彈性構件收縮時’在第2扣合要素1 4，會形成具有 蛇腹構造之蛇腹形成區域1 6。彈性構件1 5係安裝於第2 -10- 200924724 扣合要素14的縱方向Y的大致中央’在此中央部分形成 有蛇腹形成區域16。在蛇腹形成區域16 ’藉由彈性構件 15的收縮力，形成皺摺’藉由此皺摺’形成對第1扣合要 素13側呈凸狀之複數個頂部17。頂部17係延伸於横方向 X並且分離於縱方向Υ。第2扣合要素14固定於吸液性 本體2的後側緣部1 2 ’但因吸液性本體2係使用肌膚觸感 柔軟之不織布，所以’若蛇腹形成區域1 6收縮的話’吸 φ 液性本體2也伴隨此收縮而收縮。 彈性構件1 5未使收縮力作用於第2扣合要素1 4的上 端部1 8及下端部1 9。即，在上下端部1 8、1 9 ’形成不具 有頂部17之平坦區域20、21。平坦區域20、21，其縱方 向Υ的尺寸大約爲30mm，但能將此尺寸設定於10mm以 上50mm以下。這是由於若較10mm小之情況時，如後述 說明之定位時的卡合變弱，此卡合不穩定，而當較50mm 大時，在進行定位時折皺，造成皺摺進入之故。第2扣合 φ 要素14的彈性構件15之未使收縮力作用之狀態的縱方向 Y的尺寸及第1扣合要素13的縱方向Y的尺寸大約設爲 13〇mm，這些第1及第2扣合要素13、14的横方向X的 尺寸大約設爲20mm。 藉由卡合這些第1及第2扣合要素13、14,連結前 腰圍區域8與後腰圍區域9，紙尿褲1成爲圖1所示之短 褲形狀。在短褲形狀的紙尿褲1，藉由前腰圍區域8與後 腰圍區域9的開口緣22、23區劃成腰圍開口 24，藉由跨 下區域10的腳開口緣25區劃成一對的腳開口 26。在前後 -11 - 200924724 腰圍開口緣22、23，沿著此開口緣22、23將腰圍彈性構 件27在伸長狀態下予以安裝，在腳開口緣25，沿著開口 緣2 5將腳彈性構件2 8在伸長狀態下予以安裝。腰圍彈性 構件27及腳彈性構件28具有複數條的橡膠線’藉由运些 橡膠線的收縮力，使前後腰圍開口緣22、23及腳開口緣 25與穿著用者吻合（合身）° 在前後腰圍區域8、9的縱方向Y之大致中央區域’ ❹ 用來提昇紙尿褲對穿著用者之吻合性的補助彈性構件29 在伸長狀態下被安裝著。補助彈性構件2 9係具有朝腰圍 周圍方向Z延伸且分離於縱方向Y之複數條的橡膠線’藉 由這些橡膠線的收縮力，使得前後腰圍區域的中央區域與 穿著用者吻合。 腰圍彈性構件27、腳彈性構件28及補助彈性構件29 能夠使用天然橡膠或聚胺甲酸酯等的合成橡膠，亦可使用 具有彈性的纖維不織布、塑膠薄片等，來代替橡膠線。 Ο 在這樣的紙尿褲1，使用圖3〜5，針對卡合第1扣合 要素13與第2扣合14之情況進行說明。圖3係顯示第1 扣合要素13與第2扣合要素14之卡合部分的圖，圖4係 圖3的IV-IV線端面圖。 如圖3及4所示’在第1扣合要素13的上端部30重 疊第2扣合要素14的上端部18即平坦區域2〇，將這些要 素卡合。第1扣合要素13在其縱方向Y的全長範圍呈平 坦’由於在該上端部3〇重疊第2扣合要素14的平坦區域 20’故’迫些要素在其全面上卡合’能夠進行第1扣合要 -12- 200924724 素13與第2扣合要素14之定位。 如圖4所示，在使第！扣合要素13的上端部3〇與第 2扣合要素14的平坦區域20卡合之期間，會有第〗扣合 要素13與第2扣合要素14之其他區域不小心接觸而卡合 之情況。但’在第2扣合要素14’因在其中央部分具備有 蛇腹形成區域1 6 ’此蛇腹形成區域1 6具有複數個頂部}7 ，所以’僅該頂部17卡合於第1扣合要素I〗。即，卡合 〇 之面積僅有稍許，容易使這些要素之卡合脫離。例如，僅 夾持第2扣合要素14的下端部19的附近，朝第1扣合要 素13分離的方向（圖4的左側）拉引，可使得蛇腹形成 區域16容易從第1扣合要素13剝離。如此，即使夾持下 端部19來剝離蛇腹形成區域16，也因第1扣合要素13的 上端部30與第2扣合要素14的平坦區域20係在其全面 強固地卡合，所以，不會有隨著蛇腹形成區域1 6的剝離 而被剝離之情況產生。 〇 其次，在適當的位置使已剝離的第2扣合要素丨4的 蛇腹形成區域1 6卡合於第1扣合要素1 3。即，例如夾持 形成於第2扣合要素14的下端部19之平坦區域21，將其 朝縱方向Y的下方（圖4的下側）拉引。第2扣合要素 14在其上端部18的平坦區域20，與第1扣合要素13強 固地卡合，因此，當拉引下端部19的平坦區域21時，則 如圖5所示，蛇腹形成區域16的蛇腹構造伸長，第2扣 合要素14全體朝縱方向Y的下方伸長。在蛇腹形成區域 16伸長的狀態下，將此下端部I9的平坦區域21卡合於第 -13- 200924724 1扣合要素13的下端部31，進一步將已經伸長的蛇腹形 成區域16壓於第1扣合要素13後進行卡合。因伸長的蛇 腹形成區域16大致成爲平坦狀，所以，在其全面卡合於 第1扣合要素1 3，能夠增強卡合力。 如以上所述’藉由在第2扣合要素14設置蛇腹形成 區域16’即使在第1扣合要素13與第2扣合要素14不小 心卡合之情況’也能容易使該卡合脫離而重新進行卡合， 0 在以全體將第1扣合要素13與第2扣合要素14卡合之情 況，能夠強固且正確地卡合。 因將後腰圍區域9重疊於前腰圍區域8的外側，將該 等區域予以連結，所以，第2扣合要素14安裝於位在外 側之後腰圍區域9。因第2扣合要素14的蛇腹形成區域 1 6位於所重疊的外側的側緣部，所以容易進行將其延伸之 作業。在將前腰圍區域8重疊於後腰圍區域9的外側之情 況，亦可在第1扣合要素13形成蛇腹形成區域。 Φ 將第1扣合要素13作爲鉤要素，並將第2扣合要素 14作爲環要素，但並非僅限於此，若爲可將前後腰圍區域 8、9能裝卸地加以連結者的話，亦可使用例如感壓性黏合 帶等的其他扣合要素。又，亦可將第1扣合要素13作爲 環要素’而將第2扣合要素14作爲鉤要素。在此實施形 態’將第1扣合要素13直接安裝於外面薄片7，而將第2 扣合要素14直接安裝於內面薄片6，但，亦可另外設置用 來保持這些扣合要素之薄片，再將此保持薄片安裝於內面 薄片6或外面薄片7。 -14- 200924724 彈性構件15,於第2扣合要素14與內面薄片6之間 在伸長狀態下被安裝著，但，亦可在將第2扣合要素14 安裝於內面薄片6之際同時安裝，亦可在將彈性構件15 安裝於第2扣合要素14後，將這些構件安裝於內面薄片6 。若爲可將彈性構件15的收縮力賦予第2扣合要素14者 的話即可。 圖6〜8係顯示第1發明之第2實施形態的圖。此第 φ 2實施形態，在第2扣合要素1 4的蛇腹構造之形成方法上 與第1實施形態不同。針對其他構成要素，因與第1實施 形態相同，針對相同的構成要素省略其詳細說明。 在此第2實施形態，藉由利用齒輪機構32之加熱變 形，來形成第2扣合要素14的蛇腹構造。因此，至少第2 扣合要素1 4係以熱可塑性樹脂形成的。 如圖6所示，使第2扣合要素14通過構成齒輪機構 32的第1齒輪33與第2齒輪34之間，來在第2扣合要素 φ 14形成蛇腹構造。第2扣合要素14在安裝於後腰圍區域 9之內面薄片6的後側緣部12的狀態下，與內外面薄片6 、7 —同供給至齒輪機構32。第1齒輪33被加熱至大約 140 °C，對第1齒輪33，第2扣合要素14的環能與其接觸 的方式加以供給第2扣合要素14。第2齒輪34設置於大 約 20°C。 第1齒輪33及第2齒輪34具有如圖7所示的這種嚙 合狀。即，在第1齒輪33的凹部33a與第2齒輪34的凸 部3 4b之嚙合，凹部33a與凸部34b之間隔狹窄，所供給 -15- 200924724 之第2扣合要素14及內外面薄片6、7作成爲與凹部33a 及凸部34b接觸之尺寸關係。在第1齒輪33的凸部33b 與第2齒輪34的凹部34a之嚙合’凸部33b與凹部34a 之間隔，比起凹部33a與凸部34b之間隔寬廣，作成爲即 使供給有第2扣合要素14及內外面薄片6、7之情況，第 1齒輪33或第2齒輪34也不會與其接觸之尺寸關係。 藉由對齒輪機構32供給第2扣合要素14及內外面薄 φ 片6、7並予以加熱，在第2扣合要素14及內外面薄片6 、7，形成配合齒輪形狀之蛇腹構造。即，藉由第1齒輪 33的凹部33a與第2齒輪34的凸部3 4b，形成複數個頂 部17。且，由於在第1齒輪33的凹部33a與第2齒輪34 的凸部34b之間，第2扣合要素14的環被壓於凸部34b 後再與凹部33a接觸，故，所按壓之環被加熱沖壓。因加 熱沖壓，使得環熔融，不會維持環的形狀，使得無法進行 與第1扣合要素13的鉤之卡合。即，在頂部17，未形成 ❹ 環。 將這樣的第2扣合要素14安裝於第1扣合要素13之 順序，係與第1實施形態相同。在此第2實施形態，在將 第1扣合要素13的上端部30與第2扣合要素14的上端 部1 8即平坦區域20接合並予以定位的期間，即使在第2 扣合要素14的蛇腹形成區域16與第1扣合要素13接觸 的情況，因在頂部1 7，形成爲不能卡合，所以，不會產生 第1扣合要素13a與第2扣合要素14不小心卡合一事產 生。在定位後，拉引位於第2扣合要素14的下端部19之 -16- 200924724 平坦區域21使蛇腹構造伸長，並卡合至第1扣合 ，藉此可將這些要素予以強固地卡合。 若根據此實施形態的話，因藉由齒輪機構32 蛇腹形成區域16，所以，蛇腹的尺寸即由頂部17 35爲止之尺寸呈一定，並且在寬度方向X全範圍 成頂部17及底部35。因此，當拉引了平坦區域21 夠使蛇腹構造均等地伸長，能夠在更接近平坦之狀 0 卡合至第1扣合要素13，達到強固的卡合。 在此實施形態之蛇腹構造收縮時的頂部17間 大約爲7mm，由頂部17至底部35爲止之尺寸大約 。該尺寸係依據第2扣合要素14或內外面薄片6、 性等加以適宜決定者，不限於此數値。 在齒輪機構32，將第2扣合要素14在安裝於 片6的狀態下加以供給，但，亦可僅供給第2扣合 來形成蛇腹構造，然後再將第2扣合要素14安裝 ❹ 薄片6。 亦可將第1實施形態之彈性構件1 5設置於第 形態之第2扣合要素1 4。在此情況，僅將第2扣 14供給至齒輪機構32，形成蛇腹構造後，將其伸 裝於後側緣部12，並且，在第2扣合要素14與後 1 2的內面薄片6之間將彈性構件1 5在伸長狀態下 裝。藉由具備有彈性構件15,使得即使在反復進行 合要素13與第2扣合要素14之裝卸的情況，也能 蛇腹形成區域1 6之蛇腹構造。 要素13 來形成 至底部 上，形 時，能 態下， 之尺寸 爲3mm 7的剛 內面薄 要素1 4 至內面 2實施 合要素 長並安 側緣部 予以安 第1扣 夠維持 -17- 200924724 <第2發明> 圖9〜12係顯示第2發明之第1實施形態的圖，以大 人用紙尿褲爲例進行說明。如圖9所示，紙尿褲201包含 具有吸液性的本體202與扣合手段3 03。本體202具有縱 方向Y、橫方向X及周方向Z、以及身體側內面204及穿 衣側外面205。本體202包含有：形成身體側內面204之 內面薄片206 ;形成穿衣側外面205之外面薄片207 ;及 φ 介裝於這些內外面薄片206、20 7之間的吸液性芯材（未 圖示）。內面薄片206能夠使用透液性的不織布等、外面

前側緣部211的外面薄片207，藉由接著或熔融安裝有由 環要素所構成之第1扣合要素213。 在後側緣部212的內面薄片206，藉由接著或熔融， 安裝有與第1扣合要素213可裝卸地卡合並由鉤要素所構 成之第2扣合要素214。藉由第1扣合要素213與第2扣 合要素214’形成第2發明的扣合手段303。 第1及第2扣合要素2 1 3、2 1 4具有與前後側緣部 -18- 200924724 211、212的縱方向γ的尺寸大致相同之長度尺 扣合要素213包含有：與横方向X相對向並延伸 Υ之內外側緣215、216;及與縱方向Υ相對向 横方向X之上下端緣217、218。第2扣合要素 有：與横方向X相對向並延伸於縱方向Υ之內外 ’ 220 ;及與縱方向γ相對向並延伸於横方向X 緣2 1 2、222。內側緣2 1 5、2 1 9係比起外側緣2 1 0 分別位於更靠近本體202的横方向X的內側。 圖10係詳細地顯示第2扣合要素214之圖 般’在第2扣合要素214，形成有容易進行此第 素2 14的折彎作業之折彎誘導手段223。第2 214係藉由聚烯烴系樹脂特別是聚丙烯與聚乙烯 所形成之具熱可塑性的要素，折彎誘導手段223 藉由對第2扣合要素214進行熱加工所形成之 224。藉由對具有熱可塑性之第2扣合要素214 φ 工’比起折彎區域224中未進行熱加工之其他部 性高且厚度薄，依據該剛性及厚度之差異，容易; 折彎區域224包含有上端緣221側的上端折 、和下端緣222側的下端折彎線226，第2扣合 在上端折彎線225與下端折彎線226之間被折彎 折彎線225至下端折彎線226爲止的尺寸t大 20mm。這是由於當尺寸t爲3mm以下時，則形 2扣合要素214的厚度窄變得不易折彎，而當較 廣時’則未與第1扣合要素213接合之部分變大 寸。第1 於縱方向 並延伸於

224容易折彎。又，因折彎區域224傾斜成從外側緣220 朝內側緣2 1 9後退，所以能夠將下部2 2 8朝周方向Z外側 折彎。因將下部2 2 8朝周方向Z外側折彎，所以，比起朝 內側折彎之操作，更容易進行折彎操作，能夠防止下部 228不小心卡合至桌1扣合要素213，並且能夠防止因下 部228的鉤要素造成穿著用者肌膚受傷。 如前述記載，將折彎區域224的角度《設爲30〜60。 Q 。當角度α較30°小時，必須折彎成使下部228與上部 227重疊，不易折彎’並且因該折彎操作會受到腳開口緣 234所阻礙。當角度〇；較60°大時，將上部227卡合至第1 扣合要素213之際的縱方向Y的接合距離實質上變長，將 上部22 7正確地安裝至第1扣合要素213作業變得困難。 在將下部228折彎狀態下，使第2扣合要素214的上 端緣22 1與第1扣合要素213的上端緣217重疊的方式， 將第2扣合要素214的上部227卡合至第1扣合要素213 。如圖12所示，因在已經卡合了上部227之狀態下，下 -22- 200924724 部228被折彎’所以’不會有該下部228不小心卡合至第 1扣合要素213 —事產生。在將上部227與第1扣合要素 213穩固地卡合後’使下部228的折彎返回至原狀，再將 其與第1扣合要素213卡合。此時，因上部22 7穩固地卡

Q [Embodiment] <First Invention> Figs. 1 to 5 show a first embodiment of the first invention, and an adult diaper will be described as an example. As shown in Fig. 1, the diaper 1 includes a liquid-absorbent body 2 and a fastening means 3. The liquid-absorbent body 2 has a longitudinal direction Υ, a lateral direction X and a waist circumference direction Ζ, and a body side inner surface 4 and a garment side outer surface 5 . The liquid-absorbent body 2 includes an inner sheet 6 forming a body-side inner surface 4, an outer sheet 7 forming a garment-side outer surface 5, and a liquid-absorbent core material interposed between the inner and outer sheets 6, 7. (not shown). Such liquid absorbing property -9-200924724 The main body 2 includes a front waistline region 8, a rear waistline region 9, and a cross-sectional area 1〇 between the front and rear waistline regions 8, 9. In the front waistline region 8, a side edge portion 11' is formed in the rear waistline region 9 so as to face the lateral direction X and extend in the longitudinal direction Y, and a side edge portion is formed to extend in the lateral direction X and extend in the longitudinal direction Y. 1 2. The first fastening element 13 composed of the hook elements is attached to the outer sheet 7 of the front side edge portion 11 by melting or melting. In the inner sheet 6 of the rear side edge portion 12, the second fastening element 14 composed of the loop elements that can be detachably engaged with the first fastening element 13 is attached or fused. The elastic member 15 extending in the longitudinal direction Y between the inner sheet 6 and the second fastening element 14 is attached in an extended state. Further, the first engagement element 13 has a size that is substantially the same as the dimension of the front side edge portion 11 in the longitudinal direction γ. In Fig. 1, the second engaging element 14 and the rear side edge portion 12 are contracted by the elastic member 15, and in the extended state, the members are substantially the same in the longitudinal direction Y, and the first engaging element 13 and the second φ buckle are The dimension of the vertical direction Y of the combined element 14 is also substantially the same. Fig. 2 is a cross-sectional view taken along line II-II of Fig. 1. As shown in the figure, four rubber cords were used as the elastic members 1 5 ' at intervals of 5 m in the width direction X. This rubber cord is a synthetic rubber of polyurethane, but the kind of the elastic member j 5 is not limited thereto. Other materials may be used. The number of the elastic members 15 to be used can also be appropriately selected in accordance with the relationship of other materials. As shown in Fig. 1, the elastic member 15 is attached in an extended state, and when these elastic members are contracted, a bellows forming region 16 having a bellows structure is formed in the second engaging element 14. The elastic member 15 is attached to the substantially central portion of the longitudinal direction Y of the second -10-200924724 fastening element 14, and a bellows formation region 16 is formed at the central portion. In the bellows forming region 16', a wrinkle is formed by the contraction force of the elastic member 15, and a plurality of top portions 17 which are convex toward the first engaging element 13 side are formed by the wrinkles. The top 17 series extends in the transverse direction X and is separated from the longitudinal direction. The second fastening element 14 is fixed to the rear edge portion 1 2 ' of the liquid-absorbent main body 2, but the liquid-absorbent main body 2 is a non-woven fabric which is soft to the touch of the skin, so if the bellows formation region 16 contracts, the suction φ The liquid body 2 also contracts with this shrinkage. The elastic member 15 does not apply a contracting force to the upper end portion 18 and the lower end portion 19 of the second engaging element 14 . That is, the flat regions 20, 21 having no top portion 17 are formed at the upper and lower end portions 18, 19'. The flat regions 20, 21 have a dimension of about 30 mm in the longitudinal direction, but the size can be set to be 10 mm or more and 50 mm or less. This is because if the case is smaller than 10 mm, the engagement at the time of positioning as described later becomes weak, and the engagement is unstable, and when it is larger than 50 mm, it wrinkles during positioning, causing wrinkles to enter. The dimension of the longitudinal direction Y of the elastic member 15 of the second engagement φ element 14 that does not cause the contraction force to act and the dimension of the longitudinal direction Y of the first fastening element 13 are approximately 13 mm, and these first and second The dimension of the lateral direction X of the fastening elements 13 and 14 is approximately 20 mm. By engaging the first and second fastening elements 13 and 14, the front waistline region 8 and the rear waistline region 9 are coupled, and the diaper 1 has the shape of a pants as shown in Fig. 1 . The diaper 1 in the shape of a shorts is divided into a waist opening 24 by the front waist regions 8 and the opening edges 22, 23 of the rear waist region 9, and is divided into a pair of foot openings 26 by the foot opening edges 25 of the straddle region 10. The waist elastic members 27 are attached to the waist opening members 22, 23 in the front and rear -11 - 200924724, and the waist elastic members 27 are attached in the extended state along the opening edges 22, and the foot elastic members 2 are formed along the opening edges 25 at the foot opening edges 25. 8 Installed in an extended state. The waist elastic member 27 and the leg elastic member 28 have a plurality of rubber threads'. By the contraction force of the rubber wires, the front and rear waist opening edges 22, 23 and the foot opening edge 25 are fitted (fitted) with the wearer. A substantially central region of the waist regions 8 and 9 in the longitudinal direction Y ❹ The auxiliary elastic member 29 for improving the fit of the diaper to the wearer is attached in an extended state. The auxiliary elastic member 209 has a plurality of rubber cords extending in the waist-surrounding direction Z and separated from the longitudinal direction Y by the contraction force of the rubber threads, so that the central region of the front and rear waist regions coincides with the wearer. The waist elastic member 27, the leg elastic member 28, and the auxiliary elastic member 29 can be made of a synthetic rubber such as natural rubber or polyurethane, or a flexible fiber nonwoven fabric, a plastic sheet or the like can be used instead of the rubber thread. In the case of such a diaper 1, the case where the first fastening element 13 and the second fastening 14 are engaged will be described with reference to Figs. Fig. 3 is a view showing an engagement portion between the first engagement element 13 and the second engagement element 14, and Fig. 4 is an end view taken along line IV-IV of Fig. 3. As shown in Figs. 3 and 4, the upper end portion 30 of the first engaging element 13 overlaps the upper end portion 18 of the second engaging element 14, that is, the flat portion 2, and these elements are engaged. The first fastening element 13 is flat over the entire length of the longitudinal direction Y. Since the flat portion 20 of the second fastening element 14 is superposed on the upper end portion 3, the component is forced to be fully engaged. The first snap-in -12- 200924724 Prime 13 and the second snap-in element 14 are positioned. As shown in Figure 4, in making the first! While the upper end portion 3 of the engaging element 13 is engaged with the flat region 20 of the second fastening element 14, the first fastening element 13 and the other regions of the second fastening element 14 are inadvertently contacted and engaged. Happening. However, 'the second fastening element 14' has a bellows formation region 16' in the central portion thereof. The bellows formation region 16 has a plurality of tops}7, so that only the top portion 17 is engaged with the first fastening element. I〗. That is, the area of the engagement 仅有 is only slightly, and it is easy to disengage these elements. For example, the vicinity of the lower end portion 19 of the second engaging element 14 is sandwiched, and the direction in which the first engaging element 13 is separated (the left side in FIG. 4) is pulled, so that the bellows forming region 16 can be easily removed from the first engaging element. 13 peeling. In this manner, even if the lower end portion 19 is sandwiched to peel the bellows formation region 16, the upper end portion 30 of the first fastening element 13 and the flat region 20 of the second fastening element 14 are strongly engaged with each other. Therefore, There is a case where it is peeled off as the bellows forming region 16 is peeled off. Next, the bellows formation region 16 of the peeled second fastening element 丨4 is engaged with the first fastening element 13 at an appropriate position. In other words, for example, the flat region 21 formed on the lower end portion 19 of the second engaging element 14 is sandwiched and pulled downward in the longitudinal direction Y (lower side in Fig. 4). The second engaging element 14 is strongly engaged with the first engaging element 13 in the flat region 20 of the upper end portion 18. Therefore, when the flat portion 21 of the lower end portion 19 is pulled, as shown in FIG. 5, the bellows The bellows structure of the formation region 16 is elongated, and the entire second fastening element 14 is elongated downward in the longitudinal direction Y. In a state in which the bellows forming region 16 is elongated, the flat region 21 of the lower end portion I9 is engaged with the lower end portion 31 of the engaging element 13 of the -13 to 200924724, and the bellows forming region 16 that has been elongated is further pressed to the first portion. After the element 13 is fastened, the engagement is performed. Since the stretched bellows forming region 16 is substantially flat, the engaging force can be enhanced by fully engaging the first engaging element 13 with the engaging element. As described above, by providing the bellows forming region 16' in the second fastening element 14 even if the first fastening element 13 and the second fastening element 14 are accidentally engaged, the engagement can be easily released. When the first engagement element 13 and the second engagement element 14 are engaged with each other, 0 can be strongly and accurately engaged. Since the rear waistline region 9 is superposed on the outer side of the front waistline region 8, the regions are connected. Therefore, the second fastening component 14 is attached to the waistline region 9 after being positioned on the outer side. Since the bellows forming region 16 of the second engaging element 14 is located at the side edge portion of the outer side which is overlapped, it is easy to perform the work of extending the same. In the case where the front waistline region 8 is superposed on the outer side of the rear waistline region 9, a bellows formation region may be formed in the first fastening element 13. Φ The first fastening element 13 is used as the hook element, and the second fastening element 14 is used as the ring element. However, the second fastening element 14 is not limited thereto, and the front and rear waist regions 8 and 9 can be detachably coupled. Other fastening elements such as a pressure-sensitive adhesive tape are used. Further, the first fastening element 13 may be referred to as a loop element ', and the second fastening element 14 may be a hook element. In this embodiment, the first fastening element 13 is directly attached to the outer sheet 7, and the second fastening element 14 is directly attached to the inner sheet 6. However, a sheet for holding the fastening elements may be separately provided. Then, the holding sheet is attached to the inner sheet 6 or the outer sheet 7. -14- 200924724 The elastic member 15 is attached between the second fastening element 14 and the inner surface sheet 6 in an extended state, but the second fastening element 14 may be attached to the inner surface sheet 6 At the same time, the elastic member 15 may be attached to the second fastening element 14 and then attached to the inner surface sheet 6. It suffices that the contraction force of the elastic member 15 can be applied to the second fastening element 14. 6 to 8 are views showing a second embodiment of the first invention. This first φ 2 embodiment differs from the first embodiment in the method of forming the bellows structure of the second fastening element 14. The other components are the same as in the first embodiment, and the detailed description of the same components will be omitted. In the second embodiment, the bellows structure of the second engaging element 14 is formed by the heating deformation of the gear mechanism 32. Therefore, at least the second fastening element 14 is formed of a thermoplastic resin. As shown in Fig. 6, the second engagement element 14 is passed between the first gear 33 and the second gear 34 which constitute the gear mechanism 32, and the bellows structure is formed in the second engagement element φ14. The second engaging element 14 is supplied to the gear mechanism 32 together with the inner and outer sheets 6 and 7 in a state of being attached to the rear side edge portion 12 of the inner sheet 6 of the rear waist region 9. The first gear 33 is heated to approximately 140 °C, and the second engagement element 14 is supplied to the first gear 33 so that the ring of the second engagement element 14 can come into contact therewith. The second gear 34 is set at about 20 °C. The first gear 33 and the second gear 34 have such a meshing shape as shown in Fig. 7 . In other words, the concave portion 33a of the first gear 33 meshes with the convex portion 34b of the second gear 34, and the interval between the concave portion 33a and the convex portion 34b is narrow, and the second fastening element 14 and the inner and outer sheets of -15-200924724 are supplied. 6, 7 is made to have a dimensional relationship with the concave portion 33a and the convex portion 34b. The distance between the convex portion 33b of the first gear 33 and the concave portion 34a of the second gear 34 is such that the distance between the convex portion 33b and the concave portion 34a is wider than the distance between the concave portion 33a and the convex portion 34b, so that even if the second fastening is supplied In the case of the element 14 and the inner and outer sheets 6, 7, the first gear 33 or the second gear 34 does not have a dimensional relationship with it. By supplying the second engaging element 14 and the inner and outer thin φ sheets 6, 7 to the gear mechanism 32 and heating the same, the second engaging element 14 and the inner and outer sheets 6 and 7 are formed into a bellows structure having a gear shape. That is, a plurality of top portions 17 are formed by the concave portion 33a of the first gear 33 and the convex portion 34b of the second gear 34. Further, since the ring of the second engaging element 14 is pressed against the convex portion 34b between the concave portion 33a of the first gear 33 and the convex portion 34b of the second gear 34, and then the concave portion 33a is in contact with each other, the pressed ring is pressed. It is heated and stamped. Since the ring is melted by the hot stamping, the shape of the ring is not maintained, and the engagement with the hook of the first fastening element 13 cannot be performed. That is, at the top portion 17, no ❹ ring is formed. The order in which such a second fastening element 14 is attached to the first fastening element 13 is the same as that of the first embodiment. In the second embodiment, the upper end portion 30 of the first engaging element 13 and the upper end portion 18 of the second engaging element 14 are joined and positioned, even in the second engaging element 14 When the bellows forming region 16 is in contact with the first engaging element 13, the top portion 17 is formed so as not to be engaged, so that the first engaging element 13a and the second engaging element 14 are not accidentally engaged. The matter arises. After positioning, the 16-200924724 flat region 21 located at the lower end portion 19 of the second fastening element 14 is stretched to extend the bellows structure and snap to the first snap, whereby the elements can be firmly engaged. . According to this embodiment, since the region 16 is formed by the bellows mechanism 32, the size of the bellows is constant from the top portion 1735, and the top portion 17 and the bottom portion 35 are formed in the width direction X. Therefore, when the flat region 21 is pulled up so that the bellows structure is equally elongated, it can be engaged to the first fastening element 13 in a more flat state, and a strong engagement can be achieved. When the bellows structure of this embodiment is contracted, the top 17 is about 7 mm, and the size from the top 17 to the bottom 35 is about. The size is appropriately determined depending on the second fastening element 14 or the inner and outer sheets 6, the properties, and the like, and is not limited to this number. In the gear mechanism 32, the second fastening element 14 is supplied while being attached to the sheet 6. However, the second fastening may be supplied only to form the bellows structure, and then the second fastening element 14 may be attached to the sheet. 6. The elastic member 15 of the first embodiment may be provided in the second fastening element 14 of the first embodiment. In this case, only the second buckle 14 is supplied to the gear mechanism 32, and after forming the bellows structure, it is stretched to the rear side edge portion 12, and the inner surface sheet 6 of the second fastening element 14 and the rear portion 12 is formed. The elastic member 15 is mounted between the stretched states. By providing the elastic member 15, the bellows structure of the region 16 can be formed even if the combined element 13 and the second fastening element 14 are repeatedly attached or detached. The element 13 is formed on the bottom portion. When the shape is in the energy state, the inner thin surface element 1 4 to the inner surface 2 having a size of 3 mm 7 are subjected to the length of the joint element and the side edge portion is secured by the first one to maintain -17. - 200924724 <Second Invention> Figs. 9 to 12 are views showing a first embodiment of the second invention, and an adult diaper will be described as an example. As shown in Fig. 9, the diaper 201 includes a body 202 having a liquid absorbing property and a fastening means 303. The body 202 has a longitudinal direction Y, a lateral direction X, and a circumferential direction Z, and a body side inner surface 204 and a garment side outer surface 205. The body 202 includes: an inner surface sheet 206 forming a body side inner surface 204; an outer surface sheet 207 forming a garment side outer surface 205; and a liquid absorbing core material interposed between the inner and outer sheets 206, 20 7 ( Not shown). The inner sheet 206 can be a liquid-permeable nonwoven fabric or the like, the outer sheet 207 can be a liquid-impermeable film or the like, and the liquid-absorbent core material can be used as a mixture of fluff pulp and superabsorbent polymer particles, and the like. Conventional materials. Such body 202 includes a front waistline region 208: a rear waistline region 209; and a straddle region 210 between the front and rear waist regions 208,209. In the front waistline region 208, a side edge portion 211 that faces the lateral direction X and extends in the longitudinal direction Y is formed, and in the rear waistline region 209, a side edge portion that faces the lateral direction X and extends in the longitudinal direction γ is formed. 2丨2. In the outer sheet 207 of the front side edge portion 211, the first fastening element 213 composed of the loop elements is attached or fused. The inner surface sheet 206 of the rear side edge portion 212 is attached to the second fastening element 214 which is detachably engaged with the first fastening element 213 by hook elements. The fastening means 303 of the second invention is formed by the first fastening element 213 and the second fastening element 214'. The first and second engaging elements 2 1 3 and 2 1 4 have substantially the same length dimension γ as the longitudinal direction γ of the front and rear side edge portions -18-200924724 211 and 212, and include: lateral direction X The inner and outer edges 215, 216 of the ridges are opposite to each other and extend, and the lower edges 217, 218 are opposed to the lateral direction X with respect to the longitudinal direction. The second engaging element has an inner and outer portion '220 that faces the lateral direction X and extends in the longitudinal direction ;; and extends in the lateral direction γ and extends in the lateral direction X edge 2 1 2, 222. The inner edges 2 1 5 and 2 1 9 are located closer to the inner side of the main body 202 in the lateral direction X than the outer edges 2 1 0 , respectively. Fig. 10 is a view showing the second fastening element 214 in detail. In the second fastening element 214, a bending inducing means 223 for facilitating the bending operation of the first element 2 14 is formed. The second 214 is a thermoplastic element formed of a polyolefin resin, particularly polypropylene and polyethylene, and the bending inducing means 223 is formed by thermally processing the second fastening element 214. It is easy to make the second fastening element 214 φ φ with thermoplasticity higher than the other portions of the bending region 224 that are not subjected to hot working, and the thickness is thin, depending on the difference in rigidity and thickness; the bending region 224 The lower end folding line 226 on the side of the upper end edge 221 and the lower end bending line 226 on the lower end edge 222 side are included. The second fastening is folded between the upper end bending line 225 and the lower end bending line 226 by the bending line 225 to the lower end. The dimension t up to the curved line 226 is 20 mm. This is because when the dimension t is 3 mm or less, the thickness of the shape 2 fastening element 214 becomes too small to be bent, and when it is wider, the portion which is not joined to the first fastening element 213 becomes large. The first direction is in the longitudinal direction and extends from 214 to include the lower end 6' 220 above the side edge 2 1 9 . As shown in the figure 2, the mixture of the fastening elements includes: Bending area For hot addition, it is just: Bend line 2 2 5 Element 214. From the upper end of about 3~ to be more than the 20th m m, the engagement of the front waistline regions 208, 2 09 of the front -19-200924724 is easily separated. The upper and lower end bending lines 225 and 226 are respectively formed in the range from the outer edge 220 to the inner edge 2 1 9 , and include the outer edge portions 225 a and 226 a on the outer edge 220 and the inner edge portion 225 b on the inner edge 219 . 22 Bb. The upper and lower end bending lines 225 and 226 are formed in a substantially parallel shape, and the outer end edge portions 225a and 226a are located closer to the upper end edge 221 than the inner end edge portions 225b and 226b. That is, the bending region 224 is inclined to the longitudinal center line P-P in which the H 2 fastening element 214 is divided into two equal parts in the lateral direction X. The angle α formed by the vertical line Q-Q of the longitudinal center line P-P and the extension line of the upper end bending line 22 5 is set to 3 0 to 60 °. More preferably, it is about 4 5 °. The dimension Α of the longitudinal direction 为止 from the upper edge 221 to the lower edge 222 of the second fastening element 214 is approximately 130 mm, and the dimension B of the longitudinal direction Y from the upper edge 221 to the outer edge 225a is approximately 10 to 50 mm. The dimension C in the width direction X from the inner edge 219 to the outer edge 220 of the second fastening element 2I4 is approximately 15 mm. However, these dimensions may be suitably changed depending on the size of the diaper pants or the type of material selected. The second fastening element 214 is defined by the bending region 224, and the upper end edge 221 side is the upper portion 227 and the lower end edge 222 side is the lower portion 228, and is vertically divided into two. Figure 11 is an end view of the longitudinal center line P-P of Figure 10 . The second fastening element 214 is heated and pressurized at about 120 °C from the joint surface 229 side of the main body 202. Since the second fastening element 214 has thermoplasticity, it is melted by heat and is pressurized. Thus, as shown in the figure, it is crushed to form a concave strip shape. At the same time, the hook forming surface 23 0 of the second engaging element 214 is also pressurized by -20-200924724, so that the hook element is crushed. The portion thus heated and pressurized is used as the bending region 224. Since the bending region 224 is higher in rigidity and thinner than the other portions, the second fastening element 2 1 4 is easily bent along the bending region 224. The front waistline region 208 and the rear waistline region 209 are joined by engaging the first and second fastening elements 213 and 214'. The diaper 201 has a shorts shape as shown in Fig. 9 . As shown in Fig. 9, the φ diaper 201 in the shape of a shorts forms a waist opening 233' by the front and rear waist opening edges 231, 232 of the front waist region 2 〇 8 and the rear waist region 209 by the foot opening edge of the straddle region 210 234' forms a pair of foot openings 235° on the inside of the front and rear waist opening edges 231, 232, along which the waist elastic members 23 6 are mounted in an extended state, and on the inside of the foot opening edges 234 The foot elastic member 2 3 7 is attached in an extended state along the opening edge 234. The waist elastic member 2 3 6 and the leg elastic member 2 3 7 have a plurality of rubber threads, and the front and rear waist openings φ the edges 231 and 232 and the foot opening edge 234 are fitted to the wearer by the contraction force of the rubber threads. On the inner side of the substantially central portion of the longitudinal direction Y of the front and rear waist regions 208, 209, the auxiliary elastic member 23 8 for improving the fit of the diaper to the wearer is attached in an extended state. The auxiliary elastic member 23 8 has a plurality of rubber cords extending in the circumferential direction Z and separated from the longitudinal direction Y. By the contraction force of the rubber threads, the central regions of the front and rear waist regions 208 and 209 are fitted to the wearer. The waist elastic member 263, the leg elastic member 273 and the auxiliary elastic member 238' can be made of synthetic rubber such as natural rubber or polyurethane, and also - 21 - 200924724 can use elastic fiber non-woven fabric, plastic sheet, etc. In place of the rubber thread, such a diaper 201, the case where the first fastening element 213 and the second fastening element 214 are engaged will be described with reference to FIG. The second engaging element 214 located on the outer side in the circumferential direction Z is engaged with the first engaging element 2 1 3 located on the wearer side inside the circumferential direction Z. When the engagement is performed, the second fastening element 214 is bent in advance along the bending region 224. Since the bending region 0 is different from the rigidity and thickness of the other portions, the bending region 224 is easily bent. Further, since the bent region 224 is inclined to retreat from the outer edge 220 toward the inner edge 2 1 9 , the lower portion 2 28 can be bent outward in the circumferential direction Z. Since the lower portion 2 2 8 is bent outward in the circumferential direction Z, the bending operation can be more easily performed than the operation of bending toward the inner side, and the lower portion 228 can be prevented from being inadvertently engaged to the table 1 fastening element 213, and The wearer's skin is prevented from being injured by the hook elements of the lower portion 228. As described above, the angle "the bending region 224" is set to 30 to 60. Q. When the angle α is smaller than 30°, it must be bent such that the lower portion 228 overlaps the upper portion 227, which is less likely to be bent' and is obstructed by the foot opening edge 234 due to the bending operation. When the angle 〇 is larger than 60°, the joining distance of the longitudinal direction Y when the upper portion 227 is engaged with the first engaging element 213 is substantially longer, and the upper portion 227 is correctly attached to the first fastening element 213. Homework has become difficult. The upper portion 227 of the second fastening element 214 is engaged to the upper portion 227 of the second fastening element 214 so that the upper end edge 22 1 of the second fastening element 214 overlaps the upper end edge 217 of the first fastening element 213 in a state where the lower portion 228 is bent. 1 button element 213. As shown in Fig. 12, in the state in which the upper portion 227 has been engaged, the lower portion -22-200924724 portion 228 is bent 'so' so that the lower portion 228 is inadvertently engaged to the first fastening element 213. produce. After the upper portion 227 and the first fastening element 213 are firmly engaged, the bending of the lower portion 228 is returned to the original shape, and the first fastening element 213 is engaged with the first fastening element 213. At this time, since the upper portion 22 7 is firmly engaged with the first engaging element 213, no displacement occurs, and the desired position can be surely engaged. By providing the bending inducing means 223, the engagement between the first engaging element 213 and the second engaging element 214 is facilitated, and these elements can be surely engaged. As described above, the dimension b from the upper end portion 21 to the outer end edge portion 225a of the second fastening element 214 is set to 1 〇 to 50 mm. When it is shorter than 10 mm, the engagement force between the upper portion 22 7 and the first fastening element 213 is too small 'the possibility of engagement of the upper portion 227 when the lower portion 228 is engaged', and when it is longer than 50 mm At this time, it is difficult to accurately engage the upper portion 227 with the first fastening element 213. By forming the bending inducing means 223 in the rear side edge portion 212, it is possible to achieve an effect of improving the wearing feeling when the diaper 201 is worn. The folding inducing means 22 3 is more easily bent than the other parts when the diaper 201 is worn, and can be flexibly bent in accordance with the movement of the wearer's body to be deformed in accordance with the wearer's body. When the bending induction means 2 2 3 is not formed, the wearing feeling is deteriorated due to the rigidity of the first and second fastening elements 213 and 214. In the above description, the first fastening element 213 is used as the ring element, and the second fastening element 214 is used as the hook element. However, the first fastening element 213 may be used as the hook element 'the second fastening element 214 as the ring element. . However, in general, -23-200924724 is more rigid than the ring element, and the hook element having a high rigidity is pressed firmly to the ring element, so that the outer side of the circumferential direction Z is used as a hook. The elements are better. As the fastening means 303, if the front and rear waist regions 208, 209 can be detachably coupled, other means such as a pressure-sensitive adhesive tape can be used. In the above, the 'bend inducing means 223' is formed only in the second engaging element 214, but may be formed in the second engaging element 213 as well. When the bending inducing means 223 is formed in both the first and second φ engaging elements 213 and 214, the card cooperation industry can be made easier. Further, the first fastening element 213 is directly attached to the outer sheet 2〇7, and the second fastening element 214 is directly attached to the inner sheet 206'. However, the sheet for holding the fastening elements may be separately provided. The holding sheet is attached to the inner sheet 206 or the outer sheet 207. In this embodiment, after the second fastening element 214 is formed with the bending inducing means 223, the second fastening element 2 1 4 is joined to the rear edge portion 2 2, but φ ' may be formed by joining the second fastening element 2 1 4 to the rear side edge portion 212 of the main body 202 to form the bending inducing means 223. Fig. 13 is a view showing a second embodiment of the second invention, showing the body side inner surface 204 of the diaper 201. In the second embodiment, the bending inducing means 223 is different from the first embodiment, and other components are the same as those in the first embodiment, and thus detailed description thereof will be omitted. In this embodiment, the bending inducing means 2 2 3 is formed by the slit portion 23 9 formed in the second fastening element 214 and the rear side edge portion 212 of the main body 202. -24- 200924724 The slit portion 2 3 9 is formed by arranging a plurality of slits 240 ′ having a plurality of slit sheets at regular intervals in a longitudinal direction in five substantially parallel rows. The length of a slit sheet is about 3 mm, and the gap between the slit sheet and the slit sheet is about 3 mm' as a slit 2400. The slit portion 239 is formed by joining the rear side edge portion 212 of the main body 202 to the second fastening element 214 and supplying it to, for example, a gear mechanism including a cutter. The position of the bending inducing means 223 formed by the slit portion 23 9 is the same as that of the first embodiment. However, the angle α of the bending region 224 is defined by the angle formed by the extension line of the slit 240 and the vertical line QQ, and the portion where the slit portion 23 9 is formed is formed, and the slit portion is not formed. In other parts, the rigidity becomes lower and it becomes easier to bend. Therefore, the lower portion 228 can be bent outward, and the upper portion 227 can be engaged with the first fastening element 213, so that the second fastening element 214 can be easily and surely engaged with the first fastening element 2 1 3 . ❾ In the above, after the second fastening element 214 is joined to the main body 202, the slit 240' is formed. However, the second fastening element 214 may be formed into the slit 240 and then joined to the main body 202. In this case, the slit 240 is formed only in the second fastening element 2 14 , and no slit is formed in the main body 202. The size of the slit sheet, the number of slits 240, and the like are not limited to the embodiment, and can be appropriately changed. Fig. 14 is a view showing a third embodiment of the second invention, characterized in that a separation portion 241' separating the upper portion 227 and the lower portion 228 of the second engagement element 214 is formed as the bending inducing means 223. The other constituent elements other than -25-200924724 are the same as those of the first embodiment, and detailed description thereof will be omitted. The separation unit 241 is formed by cutting a part of the second fastening element 214 to form a bending inducing means 223. In the second engaging element 214, the upper end bending line 225 is formed on the upper portion 227 side of the separating portion 241, and the lower end bending line 226 is formed on the lower portion 228 side. The position of the bending inducing means 223 formed by the separating portion 241 is the same as that of the first embodiment. In this embodiment, since the second engaging element 214 does not exist in the separating portion 241' where the bending inducing means 223 is formed, the rigidity of the separating portion 241 can be lowered as compared with the other portions. Therefore, the second engagement element 214 can be easily bent by the separation portion 24 1 . Fig. 15 shows a fourth embodiment of the second invention, characterized in that a high-rigidity member 242 is provided in the upper portion 227 of the second fastening element 214 as the bending inducing means 223. The components other than the features are the same as those of the first embodiment, and detailed description thereof will be omitted. 〇 As the high-rigidity member 242, a sheet-like member such as a nonwoven fabric, a woven fabric, or a film can be used, and the high-rigidity member 242 can be joined between the second fastening element 214 and the inner surface sheet 206. The high-rigidity member 242 has its upper end edge 243 substantially aligned with the upper end edge 221 of the second fastening element 214, and the lower end edge is defined as the upper end bending line 225. Further, the upper end bending line 225 also serves as the lower end bending line 226, and the lower end bending line 226 is not separately formed. In this embodiment, the upper portion 22 7 is formed by the second fastening element 214 and the high rigidity member 242, and the lower portion 228 is formed only by the second fastening element -26-200924724 214. Therefore, the difference in rigidity between the upper and lower portions 227 and 228 can be easily bent at the upper end bending line 225. In this embodiment, the high-rigidity member 242 is disposed in the entire upper portion 227. However, the high-rigidity member may be disposed only in the vicinity of the upper end bending line 22 5 . Further, the high rigidity member 242 may be disposed on the lower portion 228 side to cause a difference in rigidity from the upper portion 227.
