592675 ⑴ 玖、發明說明 【發明所屬之技術領域】 本發明，係關於被稱爲平日用棉墊之可吸收分泌物或 經血之吸收薄片、失禁患者用之吸尿薄片，再者作爲在經 血量較少日使用之經血吸收衛生棉等使用之吸收性物品， 特別是關於適於接著於內褲使用之吸收性物品。 【先前技術】 作爲薄型之吸收性物品者，有被稱爲平日用棉墊之可 吸收分泌物或經血之吸收薄片。該吸收薄片，夾介感壓接 著層接著固定於內褲之胯下部內側穿著。該以往之吸收薄 片，一般是於不透液性之背面薄片與由水針不織布等所形 成之表面薄片之間，夾介有積層纖維紙、氣流成型（air laid)紙漿等之薄型吸收層之構造。 該種吸收薄片，爲薄型且穿著者可感到與內褲同等之 軟質感者較受歡迎，且，必須於穿著狀態下不易因大腿部 之動作產生扭曲或變形，受液側之表面可維持隨時緊密接 著於身體排泄部之狀態。 【發明內容】 [發明所欲解決之技術問題] 但是，該種平日用棉墊，與平常使用之生理用衛生棉 等比較，一天內交換之頻度較小，長時間使用一片平日用 棉墊爲一般情形。因此使用時由於大腿部之動作而傳至平 (2) 曰用棉墊之變形應力，會因長時間持續作用而易於產生扭 曲或變形。如此之縐褶或變形若變得顯著，則易於產生表 面積實質上減少、液體之吸收容量降低、與身體排泄部之 緊密接著性降低無法確實捕捉排泄液，等之問題。 作爲著眼於如此之變形者，例如於日本特開 200 1 -2 76 1 26號公報，揭示有於表面薄片與吸收體之間夾介有 彈性層之平日用棉墊。又，該平日用棉墊，其上述表面薄 片及吸收層及彈性層以及位於背面之防漏薄片，是藉由形 成於比上述平日用棉墊之兩側緣部更內側之複數個壓縮部 而被壓縮固定。該平日用棉墊，是利用上述彈性層之彈性 力，對發生於穿著狀態下之扭曲賦予彈性復原力，防止上 述扭曲之產生，藉此欲提昇合貼性者。 但是，即使是如上述般具備有彈性層者，若在吸收了 體液之狀態下從兩側面重覆作用變形力時，由於該變形力 直接傳導至中央領域，故難以避免從平日用棉墊之兩側緣 部到中央領域產生大型縐褶或變形。 又’上述公報所記載者，由於在比平日用棉墊之兩側 緣部更內側處隔開較寬間隔形成有面積較大之壓縮部，故 上述縐褶或變形易於從壓縮部與壓縮部之間傳導至中央領 域。又由於個別之上述壓縮部具備有較大面積，故若該壓 縮部爲剛直者時，會有該壓縮部擋接於女性之性器而產生 不適感之虞，易於成爲裝著觸感低劣者。 本發明爲解決上述以往之課題者，目的在提供一種不 會妨礙整體之軟質感，而且來自大腿部之壓力不易傳導至 -6 - (3) (3)592675 中央領域，不易產生扭曲或縐褶等之變形之吸收性物品。 [解決問題之技術手段] 本發明之第1發明，是針對於複數片薄片重疊一起， 具備有延伸於縱長方向之左右兩側緣部、及前緣部以及後 緣部並形成爲縱長型之吸收性物品，其特徵爲： 於橫過將吸收性物品於縱長方向一分爲二之橫向方向 中心線，並延伸於縱長方向之所定長度之範圍內，於上述 兩側緣部之內側設置有第1群複數個壓著部， 上述第1群複數個壓著部，隔開所定之間隔並仿照上 述兩側緣部之形狀排列成一列，於上述壓著部所形成之排 列之兩側，分別設置有沿著複數個壓著部之排列方向延伸 之非壓著領域。 該吸收性物品若接著於內褲之胯下部之內面等穿著 時，則來自大腿部之壓力會作用於兩側緣部。由於在上述 兩側緣部之內側，隔開間隔配置有仿照兩側緣部形成排列 之壓著部，且於其兩側以具有非壓著領域之方式配置，故 藉由位於沿著排列之壓著部與壓著部中間之非壓著部及延 伸於排列兩側之非壓著領域，以及個別之壓著部之間之剛 性差或厚度之差，於壓著部，及上述非壓著部以及非壓著 領域之間會產生細微之變形，不過由於上述壓力之力量， 會藉由該細微變形而被吸收，故從外部來之壓力不易對中 央領域產生太大影響。因此，可防止大型縐褶或扭曲等之 變形產生於中央領域上。 -7- (4) (4)592675 如上述般，爲了藉兩側緣部內側之細微變形吸收作用 於兩側緣部之壓力，於上述排列內互鄰之壓著部之間隔以 在 0.5〜5 mm爲理想，上述壓著部之底面面積，以在 0.25mm2以上6mm2以下爲理想。 又在上述面積之範圍內，於上述第1群之至少一部 分，以沿著上述排列並隔開一定之間距排列有底面之形狀 爲圓、長圓、或多角形之壓著部者爲理想。不過壓著部分 別不限於上述形狀，亦可爲星型、月型等之各種形狀。 於本發明，上述兩側緣部爲凹曲線狀，上述第1群壓 著部所形成之上述排列也以凹曲線狀爲理想。 此時，來自大腿部之壓力會作用於凹曲線狀之緣部， 不過由於壓著部沿著上述凹曲線排列，故上述來自大腿部 之壓力可於分別沿著凹曲線排列之壓著部與壓著部間之非 壓著部處被吸收。 再者，於比上述第1群壓著部內側處，以夾介上述非 壓著領域設置有第2群複數個壓著部爲理想。 於該構造，在變形力超過形成排列之第1群壓著部朝 向中心方向作用時，可藉由第2群壓著部阻止該變形之傳 導，更易於防止縐褶或扭曲發生於中央領域。 該第2群壓著部之面積，亦以在0.25mm2以上6mm2 以下爲理想。 本發明之第2發明，是針對於複數片薄片重疊一起， 具備有延伸於縱長方向之左右兩側緣部，以及前緣部與後 緣部並形成爲縱長形之吸收性物品，其特徵爲： -8- (5) (5)592675 於上述兩側緣部之內側，設置有被複數個壓著部圍住 之所定面積之非壓著區劃領域，在橫斷將吸收性物品於縱 長方向一分爲二之中心線並延伸於縱長方向之所定長度之 範圍，複數個上述區劃領域沿著兩側緣部排列。 於該吸收性物品，在來自大腿部之壓力作用於兩側緣 部時，藉由因每個壓著部，以及形成於鄰接之壓著部與壓 著部間之非壓著部之剛性之差引起之細微變形，不僅可防 止應力傳導於中央領域，於被複數個壓著部圍住之非壓著 區劃領域，由於在有限之領域內，各薄片是在可彈性變形 之狀態，故該區劃領域會對於從外部來之壓力發揮緩衝機 能，中央領域之縐摺或扭曲等之變形會變得不易傳導。 此時，沿著上述兩側緣部排列之複數個上述區劃領 域，以相同形狀且相同面積爲理想。 若爲如此構成時，區劃領域會分別發揮均等之緩衝作 用，又外觀設計亦會變佳。 此時，圍住上述區劃領域之複數個壓著部之至少一部 分，底面之形狀以圓、長圓、或多角形爲理想，又上述壓 著部之底面之面積，以在0.25mm2以上6mm2以下爲理 想。 又，若在被位於一方之側緣部內側之壓著部，與位於 另一方之側緣部內側之壓著部夾住之非壓著領域之橫向方 向之距離之最小値爲20mm以上，則上述壓著部不易給予 女性性器僵硬感。又，若考慮前述之緩衝作用時，於作爲 吸收分泌物用之平日用棉墊使用時，上述距離之最小値， -9- (6) (6)592675 以在20〜35mm爲理想。 再者，在被位於一方之側緣部內側之壓著部，與位於 另一方之側緣部內側之壓著部夾住之非壓著領域上，出現 於最表面之薄片上，於橫向方向交互排列有延伸於縱長方 向之壟及溝者，最適合於本發明。 如上述般若於表面之至少中央領域具備有壟溝之構造 部，則中央領域柔軟，可減少對身體接觸刺激。但是，即 使中央領域是如此之軟質者，由於作用於兩側緣部之壓力 也易於被上述壓著部吸收，故易於防止大型縐褶、扭曲發 生於軟質之中央領域上。 【實施方式】 第1圖是將作爲本發明之一實施形態被稱爲薄型之吸 收性物品之平日用棉墊之吸收分泌物或經血之吸收薄片1 之表面側朝向面前顯示之平面圖；第2圖是將第1圖所示 之吸收薄片以將縱長方向一分爲二之橫向方向中心線Ox-Ox切開後，顯示從II箭頭方向觀察之斷面圖中之右半邊 之半斷面圖；第3圖是顯示第2圖所示之半斷面圖中之壓 著部之構造之放大斷面圖；第4圖（A) (B)是顯示於 側面固定部上之壓著部之排列圖案之第1圖之部分放大 圖。 藉以下實施形態顯示之吸收薄片1，是作爲女性將其 固定於內褲胯下部之內面，與內褲一體化者而使用之薄型 吸收性物品，是以吸收女性排泄之分泌物或生理開始時之 -10 - (7) 經血等作爲目的者。又，本發明之薄型吸收性物品，亦可 固定於女性內褲胯下部之內面作爲吸收尿失禁時之微少尿 量者而使用。 顯示於第1圖之該吸收薄片1之平面形狀爲縱長形， 具備有延伸於縱長方向之右側緣部1 A與左側緣部1 B，以 及爲朝向縱長方向兩側之端部之前緣部1 c與後緣部1 d。 右側緣部1 A及左側緣部1 B，爲凹曲線狀，在將吸收薄片 1接著於內褲胯下部之內側時，上述右側緣部1 A及左側 緣部1 B，會沿著內褲開口部之緣部。又，前緣部1 c及後 緣部1 d，爲凸曲線狀。 上述吸收薄片1之平面形狀，是夾介延伸於縱長方向 之縱長方向中心線〇y-〇y並左右對稱之形狀，又是夾介 將吸收薄片1於縱長方向一分爲二之橫向方向中心線〇χ-〇χ並前後對稱之形狀。但是’作爲該種吸收薄片1，亦 可爲夾住上述橫向方向中心線〇 X - 〇 X且前方部分及後方 部分爲非對稱之形狀者。即使是該非對稱形狀之吸收薄片 也可採用以下之構造。 如第2圖所示，上述吸收薄片1之本體部2，是藉由 背面薄片3、設置於上述背面薄片3上之中間薄片4，以 及設置於上述中間薄片4上之表面薄片5之積層體而構 成。 如第2圖所示，於上述本體部2之背面亦即上述背面 薄片3之外表面，設置有用以固定於內褲之感壓接著劑層 6。該感壓接著劑層6，是朝向寬幅方向（X方向）隔開 -11 - (8) (8)592675 間隔，並朝向縱長方向（Y方向）以直線帶狀地延伸之方 式平行地形成。而，使用前，上述感壓接著劑層6之外面 覆蓋有離型薄片7。 上述背面薄片3、中間薄片4、表面薄片5及離型薄 片7全部爲相同之平面形狀。於製造過程，背面薄片3、 中間薄片4、表面薄片5及離型薄片7是在重疊之狀態下 修剪成型，如第1圖所示，成爲具備有右側緣部1 A、左 側緣部1 B、前緣部1 c以及後緣部1 d之形狀。 於該實施形態，在縱長方向之尺寸LA之範圍內，上 述右側緣部1 A及左側緣部1 B是凹曲線狀，於上述L A之 在範圍內，在上述右側緣部1 A之內側形成有右側方固定 部1 〇。於該右側方固定部1 0，以仿照上述右側緣部1 A 之凹曲線之方式排列壓著部。同樣地，在上述LA之範圍 內，於上述左側緣部1 B之內側，以仿照上述左側緣部1 B 之凹曲線之方式形成排列有壓著部之左側方固定部1 1。 於上述前緣部1 c之內側，以仿照上述前緣部1 c之凸 曲線狀之方式設置排列有壓著部之前方固定部1 2，於後 緣部1 d之內側，以仿照上述後緣部1 d之凸曲線狀之方式 設置排列有壓著部之後方固定部1 3。 形成上述本體部2之背面薄片3、中間薄片4及表面 薄片5，是以不妨礙液體之透過及吸收之方式藉由網狀或 櫛梳狀或是螺旋狀等之圖案塗佈之熱熔型接著劑相互接著 固定一起，同時，於上述右側方固定部1 〇、左側方固定 部Π、前方固定部1 2以及後方固定部1 3，薄片彼此間被 -12- (9) (9)592675 加熱壓著固定一起。 上述背面薄片3，爲不透液性，例如是基重在2丨〜2 5 g /m2之範圍內之較薄之聚乙烯薄膜。具體上爲，將含有 無機塡充料之聚乙烯樹脂予以熔融押出，再使其延展並藉 由其含有上述無機塡充料形成有多數之微小通氣孔者。 或，上述背面薄片3，亦可爲疏水性之紡黏（spunb〇nd ) 不織布或是點黏（pointbond )不織布，或於此等不織布 層壓以通氣性之樹脂薄膜者。 中間薄片4，是具備有液體吸收機能之例如水針 (spunlace )不織布，作爲親水性纖維，是含有5 5質量 %之纖度爲1.38dtex且纖維長爲44mm之嫘縈纖維，30 質量％之纖度爲1.43dtex且纖維長爲38mm之聚酯纖維， 15質量％之纖度爲1.65dtex且纖維長爲45mm之聚丙烯 纖維者。又基重爲30〜50g/m2。 上述表面薄片5，是由第1表面薄片5A及第2表面 薄片2之2片透液性不織布所形成。 第1表面薄片5A及第2表面薄片5B，同爲由纖度爲 1.98〜2.64dtex之聚丙烯樹脂纖維所形成之紡黏不織布， 第1表面薄片5A之基重調整在20〜2 5g/m2之範圍，第2 表面薄片5B，其基重調整在20〜3 0g / m2之範圍。又亦可 爲於該紡黏不織布形成有多數之透液孔者。 如第1圖所示，於上述第1表面薄片5 A，以縱長方 向中心線〇y-〇y爲中心之所定寬幅WA之範圍內，設置有 帶狀延伸於縱長方向之壟溝成形領域1 5。如第2圖所 -13- (10) 示，於上述壟溝成形領域1 5，與延伸於縱長方向全長之 壟部1 5 A同爲延伸於縱長方向全長之溝部丨5 b，是於橫向 方向以一定之間距交互重覆地形成。 上述壟部1 5 A之高度，亦即從壟溝成形領域1 5上之 第1表面薄片5A整體之局度尺寸減掉第1表面薄片5A 之厚度之尺寸，爲0.3〜2mm之範圍，壟部15A之間距及 溝部15B之間距，爲1〜3mm之範圍。又，壟溝成形領域 15之寬幅尺寸WA，爲15〜35mm。 於第1表面薄片5 A，壟溝成形領域1 5，藉由在中央 部於所定寬幅WA之範圍內且延伸於縱長方向全長，可減 低對女性性器接觸時之刺激，成爲穿著感優異者。 第2表面薄片5B，其全面成爲壟溝成形領域16。如 第2圖及弟3圖所不’於上述第2表面薄片5B之鹽溝成 形領域1 6，延伸於縱長方向之壟部1 6 A及延伸於縱長方 向之溝部1 6 B，也於橫向方向以一定之間距交互重覆地形 成。於上述第2表面薄片5B之壟溝成形領域16之壟部 1 6 A之高度尺寸之理想範圍，以及壟部1 6 A之間距與溝部 1 6 B之間距之理想範圍，是與上述第1表面薄片5 A之壟 溝成形領域1 5 A相同。 如此，藉由在第2表面薄片5B之全面設置有壟溝成 形領域1 6，即使將本體部2整體作成薄型，將中間薄片4 作成密度高之構造，也可提高於表面側之緩衝性。又，藉 由在第1表面薄片5A以及第2表面薄片5B設置有壟溝 成形領域1 5、1 6，可將吸收薄片1之中央領域作成軟質 -14- (11) (11)592675 者，該部分會變得易於追隨配合內褲胯下部之變形。因 此，會提高對女性性器朝之緊密接著度，且於穿著中股胯 部不易感到不適。 上述壟溝成形領域1 5及1 6之成形，是藉由使形成有 對應壟溝形狀之凹凸之一對輥筒互相_合，於加熱至1 2 0 左右之輥筒間供給上述紡黏不織布之進行。藉由該加熱 以及夾壓，於不織布上賦形以壟部及溝邰。 如放大顯示於第4圖（A ) ( B )所示，上述右側方 固定部1 〇，是藉由排列3種大小之壓著部而形成。該壓 著部，具備有平面形狀爲直徑較小之圓形之第1壓著部 21、直徑比上述第1壓著部21稍微大之圓形之第2壓著 部22，以及平面爲月形之第3壓著部23。 該第1壓著部21第2壓著部22及第3壓著部23 ’ 是藉由熱壓花加工而形成。亦即’於背面薄片3之外面’ 擋接表面平滑之輥筒，從第1表面薄片5 A側，擋接具備 有對應上述各壓著部圖案之突起之壓花輥筒，藉由本體部 2被夾壓於加熱120 °C以上之上述輥筒間，進行上述熱壓 花加工。 於第2圖及第3圖，顯示上述第1壓著部21之斷面 圖。如該斷面圖所示，第1壓著部21之底面21A，藉由 上述熱壓花加工被平坦化。又，由於背面薄片3中間薄片 4及表面薄片5分別含有熱可塑性材料，故於上述底面 2 1 A，上述熱可塑性材料熔融，可使其不出現纖維凹凸之 程度地平滑化，底面21A之表面大致成爲與薄膜面同等 -15- (12) (12)592675 平滑。 又’爲了使底面21A如上述般成爲平滑之薄膜面， 使表面薄片5含有熱可塑性材料爲理想。不過，若不拘泥 於上述壓著部之底面2 1 A必須作成平滑之薄膜面，則於 表面薄片5亦可不含熱可塑性材料。例如於使用由纖維素 纖維等形成之不可熱壓著之表面薄片5時，藉由將其下面 以熱熔型接著劑接著於下層再施以熱壓花加工，亦可形成 剛性高之上述壓著部。 此於第2壓著部22及第3壓著部23也相同，第2壓 著部22之底面22A，也可作成圓形且表面平滑化者，第 3壓著部23之底面23 A，也可作成月形且表面平滑者。 如第4圖（A)所示，於上述右側方固定部1 〇，沿著 仿照右側緣部1 A之凹狀之列L 1，排列有一列第1群複數 個壓著部。於該第1群複數個壓著部，規則排列有第1壓 著部2 1及第3壓著部23。排列有上述第1群壓著部之列 L 1，是與上述右側緣部1 A相似之凹曲線狀，該曲率半徑 爲120〜3 0 0mm。又，如第3圖所示，從右側緣部1A至第 1壓著部21之底面21A之邊緣之寬幅尺寸，亦即從右側 緣部1 A至右側方固定部1 〇間之非壓著領域之寬幅尺寸 WB爲1〜8mm左右。 於該實施形態之上述第1群壓著部，成爲沿著上述列 L1，其3個第1壓著部21以及1個第3壓著部23，沿著 列L 1重覆隔開一定之間隔排列成一列之圖案。 又，於右側方固定部1 0，在上述第1群壓著部之列 -16- (13) (13)592675 L1之內側，第2群壓著部沿著列L 2排列，於該第2群壓 著部，上述第1壓著部21及第2壓著部22沿著上述列 L 2規則地排列。於該實施形態之第2群壓著部’是藉由5 個第1壓著部2 1及1個第2壓著邰2 2沿著列L 2規則地 重覆排列而形成。又構成第2群壓著部之第2壓著部 22，與構成第1群壓著部之月形之第3壓著部23相鄰 接。 排列有上述第2群壓著部之上述列L2，是於第2壓 著部2 2與第2壓著部2 2之間朝向縱長方向中心線0 y _ 〇 y 之突曲線R 1於縱長方向重覆之形狀，於該突曲線R 1 上，上述第1壓著部2 1以一定之間距間隔開排列著。 而，於被爲沿著上述列L 1排列之第1群壓著部之上 述第1壓著部21與第3壓著部23，以及爲沿著上述突曲 線R 1排列之第2群壓著部之第1壓著部2 1與第2壓著 部2 2圍住之部分形成有區劃領域2 4。於該區劃領域2 4， 背面薄片3、及中間薄片4、及第1表面薄片5A以及第2 表面薄片5B，是以沒有耢由壓花加工壓著之非壓著狀態 而存在。不過上述如般，於上述區劃領域2 4內，上述背 面薄片3、及中間薄片4、及第1表面薄片5A以及第2 表面薄片5 B，分別藉由以網狀或櫛梳狀或螺旋狀等之圖 案塗布之熱熔接著劑接著。 於上述列L2，由於是於縱長方向重覆上述突曲線r 1 而形成，故於右側方固定部1 〇，相同面積之複數個上述 區劃領域2 4，是沿著上述側緣部1 a重覆設置。又於鄰接 -17· (14) (14)592675 之區劃領域24之間位有第2壓著部22及第3壓著部 23，區間領域24及區劃領域24，成爲中間夾著壓著部地 鄰接而形成之關係。 弟3圖所不之第1壓著部21、第2壓著部22及第3 壓著部23分別之底部之橫向方向寬幅尺寸wc，是與上述 壟部15A之間距相同或其以下，Wc以在〇.5〜2.5 mm之範 圍爲理想，壓著部之底面面積以在〇.2 5〜6mm2之範圍爲理 想。若壓著部之橫向寬幅尺寸是在上述範圍且面積是在上 述範圍內，且在壟部1 5 A之間距以下，則壓著部之存在 不易被肌膚感覺到。於本發明，雖不會妨礙壟部1 5 A及 溝部1 5 B形成於第1表面薄片5 A之全面，不過於如此之 情形時只要壓著部之橫向寬幅尺寸在上述範圍內，則因壓 著部之存在而壓扁壟部15A之確率會變低，肌膚不易感 覺壓著部之存在。 又沿著列L 1之第1群壓著部之間隔5，以及沿著列 L2之第2群壓著部之間隔6，亦即位於沿著上述列L 1而 鄰接之壓著部間之非壓著部1 〇 A之尺寸ό ，以及位於沿 著列L2而鄰接之壓著部間之非壓著部1 0Β之尺寸（5以在 0.5〜5mm左右爲理想。又第1群壓著部與第2群壓著部之 橫向方向之間距Wd，在最大地方以在3〜8mm爲理想，上 述區劃領域24之面積以在15〜5 0mm2之範圍爲理想。只 要在該範圍，藉由區劃領域24之彈性變形力，作用於兩 側緣部1 A、1 B之力會不易傳導至中央部分以在。 在此，再參照放大之第4圖（B )著眼於形成沿著列 -18- (15) (15)592675 L1排列之第1群之複數個壓著部時，如上述般’壓著部 是沿著L 1排列成一列，同時於與排列方向鄰接之壓著部 間，存在有寬幅尺寸爲5之非壓著部1 Ο A。而’於沿著列 L1排列之3個第1壓著部21之左右兩側，沿著上述3個 第 1壓著部 21之排列方向，存在有延伸於以（i )及 (Π )顯示之方向之非壓著領域，第1壓著部21分別於 橫向方向成爲非壓著領域內之獨立存在者。 同樣地，若著眼於形成第2群之複數個壓著部時’如 上述般，壓著部沿著列L2之突曲線R 1排列成一列，同 時於鄰接於排列方向之壓著部間存在有寬幅尺寸6之非壓 著部1 0B。而於沿著突曲線R 1排列之5個第1壓著部2 1 之左右兩側，存在有沿著上述5個第1壓著部21之排列 方向延伸於以（iii )及（iv )顯示之方向之非壓著領域， 於第2群之第1壓著部2 1也成爲分別於橫向方向在非壓 著領域內獨立存在者。 亦即，於該實施形態，在第1群之複數個壓著部中之 任一複數個壓著部之兩側，形成有沿著該壓著部間延伸之 非壓著領域，而於該非壓著領域內分開獨立，複數個壓著 部群獨立分開踞處。而獨立壓著部群，成爲沿著上述列 L 1於複數處有間斷地排列者。此於沿著上述列L2之第2 群複數個壓著部也相同。 又，於左側方固定部1 1之各壓著部之排列狀態，是 與於右側方固定部1 〇之上述各壓著部之排列狀態左右對 稱。如第1圖所示，於右側方固定部1 〇之第2群第1壓 -19- (16) (16)592675 著部2 1，與於左側方固定部1 1之第2群第1壓著部2 1 間之間隔爲We，在橫向方向中心線Ox-Ox之位置上爲最 窄，該最窄之間隔We是20〜35 mm。若未滿上述範圍，則 右側方固定部1 〇及左側方固定部1 1之分別之壓著部會變 得易於擋接到陰唇等有損害穿著感之虞。若超過上述範 圍，則沿著列L1排列之第1群壓著部，與沿著L2排列 之第2群壓著部之間隔會變窄，區劃領域24之面積會變 太窄，於區劃領域24不能得到充分之緩衝效果。 如第1圖所示，於前方固定部12，沿著仿照吸收薄 片1之前緣部1 c之突曲線之列，規則排列有上述第1壓 著部21以及第2壓著部22。後方固定部13，是與上述前 方固定部1 2對稱，同樣地，第1壓著部2 1及第2壓著部 2 2也規則排列地形成。於設置於前方固定部1 2及後方固 定部1 3之各壓著部之底面之理想寬幅尺寸Wc及面積， 以及於排列方向之理想間隔尺寸（5等，是與上述右側方固 定部1 〇及左側方固定部Π相同。 於使用該吸收薄片1之時，要將背面側之離型薄片7 剝離，夾介感壓接著劑層6接著固定於內褲胯下部之內側 穿著。 該吸收薄片1，由於其兩側緣部1A及1 B爲凹曲線 狀’故裝著於內褲之胯下部時，兩側緣部1 A、1 B之凹曲 線，會與內褲開口部之邊緣大致一致。 於吸收性薄片1裝著於內褲之使用狀態，由於股胯部 之動作或因大腿部之緊束力，內褲之胯下部會變形。不 -20- (17) 過，由於該吸收薄片2整體爲薄型，且背面薄片3、中間 薄片4以及表面薄片5是由軟質材料所形成，故吸收薄片 1整體會易於追隨配合內褲之胯下部之變形，而於股胯部 不易產生不適感。特別是於第2表面薄片5B之全面設置 有壟溝成形領域1 6，於第1表面薄片5 A由於在中央部形 成有帶狀之壟溝成形領域1 5，故吸收薄片1之中央部分 柔軟，該中央領域會變得易於追隨配合內褲之變形。又由 於第1表面薄片5 A之壟溝成形領域1 5是要擋接女性之 性器，故對女性之性器觸感柔軟。 不過，若吸收薄片整體爲軟質者，則藉由來自大腿部 作用於兩側緣部1 A、LB之緊束壓力，首先變形力會作用 於兩側緣部1 A、1 B，該變形力會易於傳導至吸收薄片之 中央領域，其結果，會有在備有壟溝成形領域之軟質之中 央領域發生大型扭曲或縐褶之虞。 但是，於該實施形態之吸收薄片1，沿著仿照兩側緣 部1 A、1 B之列L 1，排列有隔開適度間隔之多數之較小之 第1壓著部21以及第3壓著部23，而且如第4圖（B) 所示，沿著L1之複數個第1壓著部21，在非壓著領域內 獨立踞處，因此藉由來自大腿部之緊束力等，若變形力同 時作用於內褲胯下部之緣部與上述兩側緣部1 A、1 B時， 藉由上述沿著列L 1存在之壓著部2 1、23，以及位於其間 之非壓著部1 Ο A之間之剛性差與厚度差，再者，藉由沿 著列L 1排列之複數個壓著部2 ；!以及於該兩側如（i ) (ii )所示般延伸之非壓著領域之剛性差與厚度差，在壓 -21 - (18) 著部2 1、2 3及非壓著部1 〇 A以及上述非壓著領域之間會 產生細微變形，藉此會變得可吸收且分散上述變形壓力。 因此作用於兩側緣部1 A、1 B之變形力會變得不易直接傳 導至吸收薄片1之中央領域，藉由來自側面之作用力可防 止於中央領域發生大型扭曲或縐褶。 如上述般，爲了要藉由壓著部21、23及非壓著部 1 〇 A之剛性差與厚度差，以及沿著列L 1排列之複數個壓 著部2 1及於其兩側如（i ) ( i i )所示般延伸之非壓著領 域之剛性差與厚度差，用以分散從側面來之變形力之力 量，須於上述壓著部底面之吸收薄片之厚度，及非壓著部 1 〇 A以及於上述非壓著領域之吸收薄片之厚度之差在 0 · 2 mm以上爲理想。又該差之上限沒有特別規定，不過由 於爲了作成薄型之吸收薄片，於吸收薄片之整體之厚度以 作成3mm左右爲理想，故上述厚度差之理想範圍在 0.2 〜3 m m 〇 於又上述吸收薄片1之右側方固定部1 0及左側方固 定部，在比沿著上述列L1排列之第1群壓著部更內側 處，存在有斷續之沿著列L2排列之第2群壓著部。因此 於第1群壓著部沒有被完全分散之變形應力作用於列L2 之時，構成第2群之壓著部2 1、22，及位於該壓著部間 之非壓著部1 OB，再加上於沿著列L2之壓著部2 1之兩側 如（iii ) ( iv )所示般延伸之非壓著領域，是與上述般同 樣發揮分散變形能量之機能，因此可有效阻止變形力傳導 至中央領域。 -22- (19) (19)592675 再者，由於爲斷續之壓著部圍住之區劃領域24 ’是 沿著兩側緣部1 A、1 B排列，故作用於兩側緣部1 A、1 B 之較大之縐褶等之變形力，會於上述區劃領域24被吸收 緩和。 亦即，上述區劃領域24，以所定之面積相互分開獨 立，於該內部背面薄片3、中間薄片4以及表面薄片5是 非壓著之重疊狀態。因此兩側緣部1 A、1 B承受較大之變 形力時，在各個區劃領域24內之有限之範圍內’上述各 薄片彎曲，而後發揮彈性復原力。藉由在該有限之領域內 之彎曲及彈性復原力，可防止作用於兩側緣部1 A ' 1 B之 變形力傳導於中央領域。 又，沿著列L1排列之第1群壓著部，以及沿著列L2 排列之第2群壓著部，分別爲較小，且隔開間隔地排列 者，由於各個壓著部之橫向寬幅尺寸Wc，比壟部1 5 A或 壟部1 6 A之排列間距小者爲較佳，故各個壓著部不會給 予身體僵硬感。又，較小之壓著部是沿著側緣部1 A、1 B 形成一列並斷續地配置著，而且於該兩側位有非壓著領 域，由於上述排列是獨立存在於非壓著領域內’故於兩側 緣部1 A、1 B近邊之吸收薄片1本身之剛性並沒有非常 高，並不能妨礙吸收薄片1之兩側緣部1 A、1 B沿著股胯 部彎曲變形。因此，於身體之股胯部，吸收薄片1不會給 予僵硬感。 此若與形成有沿著上述列L 1直線延伸之帶狀壓著 部，或是直線延伸之所定寬度之滾花圖案形狀之壓著部等 -23- (20) 者作對比時就更明白了。於具備有上述直線狀之壓著部或 滾花圖案形狀之壓著部者，其兩側緣部1A、1B不易彎 曲，而成爲給予身體僵硬感者，但於上述實施形態之吸收 薄片1，如上述般具備有可分散作用於兩側緣部1 A、1 B 之緊束力之力量之效果，而且不會給予身體僵硬感。 又，該吸收薄片1，於前緣部1 c以及後緣部1 d之內 側，設置有前方固定部1 2以及後方固定部1 3，其分別形 成有隔開一定間距之第1壓著部2 1及第2壓著部22。因 此於前緣部1 c及後緣部1 d附近，吸收薄片1也不會給予 身體僵硬感，而且作用於前緣部1 c及後緣部1 d之內褲之 縐褶發生力或扭曲力會與上述同樣般被吸收、分散。 以下，說明各壓著部之排列圖案之變形例。於以下之 變形例，壓著部之圖案以外之薄片積層構造、壟溝構造 等，以及其他種種理想條件等，是與上述第1圖所示之吸 收薄片1相同。 第5圖所示之實施形態之吸收薄片1 A，其在右側方 固定部1 0及左側方固定部11之壓著部之大小及排列圖 案，是與第1圖所示之吸收薄片1相同。不過於第5圖， 沒有設置前方固定部1 2及後方固定部1 3之壓著部。又， 第1表面薄片5 A之壟溝成形領域1 5，亦可設置於第5 圖，或是不設置。 於第5圖所示之吸收薄片1 A，即使無於前方固定部 1 2及後方固定部1 3之壓著部，由於亦可藉由形成於兩側 面固定部1 0及1 1之壓著部之圖案，吸收分散作用於吸收 -24- (21) (21)592675 薄片1之兩側緣部1 A、1 B之緊束力，故可有效地防止大 型縐褶或扭曲等產生於吸收薄片之中央領域。 於第6圖所示之實施形態之吸收薄片1 B，其右側方 固定部1 1 〇及左側方固定部1 1 1，是夾著縱長方向中心線 〇y-〇y成左右對稱形狀。僅說明左側方固定部111，於該 固定部111，其虛線狀之壓著部2 5是以波狀圖案形成二 列，各列之波狀圖案互相交叉，形成有由上述虛線狀之壓 著部2 5圍住之非壓著之區劃領域2 6。複數個區劃領域2 6 以仿照左側緣部1 B之方式沿著上述左側緣部丨b排列， 各個區劃領域2 6之面積皆相同。又互鄰之區劃領域2 6與 區劃領域2 6，是夾著壓著部2 5鄰接。於該實施形態，區 劃領域2 6之面積之理想範圍等，亦與第1圖所示之區劃 領域24相同。 再者於接近於左側緣邰1 B之位置，在上述虛線狀之 壓著部2 5之交叉位置，形成有2個點狀之壓著部2 7。因 此，在設定上述虛線狀之壓著部2 5，以及連結上述點狀 之壓著部2 7之線條L 3時，位於該L 3上之壓著部2 5以 及壓著部2 7，與第4圖所示之位於列L 1之壓著部同樣是 構成第1群壓著部。而，於沿著L 3排列之第1群壓著部 之內側，是夾著上述區劃領域26配置第2群壓著部之構 造。 因此，於該吸收薄片1 B，也可吸收分散作用於兩側 緣部1 A、1 B之變形應力，可防止於中央領域發生大型縐 褶或扭曲。 -25- (22) (22)592675 又’於第6圖所示之吸收薄片1 b，在前緣部1 c之內 側形成有前方固定部1 i 2，在後緣部丨d之內側形成有後 方固定部Π 3。該固定部丨丨2及〗〗3，是沿著仿照前緣部 1 c及後緣部1 d之曲線，上述第1壓著部21及第2壓著 部2 2隔開間隔而形成者，其變形力之吸收、分散機能是 與上述吸收薄片1相同。 於第7圖所示之吸收薄片1 c，其右側方固定部2 1 0 及左側方固定部2 1 1，具備有虛線狀之波浪形之壓著部 2 8 ’被該壓著部2 8圍住之部分成爲非壓著之區劃領域 2 9。於右側方固定部2〗〇及左側方固定部2丨〗，皆有相同 面積之沿著兩側緣部1 A、1 B複數排列之區劃領域2 9。 又’於前方固定部1 1 2及後方固定部2 1 3，在前緣部 1 c及後緣部1 d之內側，沿著前緣部1 ◦及後緣部1 d形成 有直線狀之壓著部3 1、3 1。 於該吸收薄片1 C，與上述同樣地亦可藉由斷續之壓 著部2 8及區劃領域2 9，吸收分散作用於兩側緣部1 A、 1 B之變形力’又可作成比兩側緣部1 A、1 B近邊更軟質 者。 於第8圖所示之吸收薄片1 D，在右側緣部1 a之內側 形成有右側方固定部3 1 0，於左側緣部1 B之內側形成有 左側方固定部3 1 1。於兩側面固定部3〗〇、3〗〗，沿著仿照 兩側緣部1 A、1 B之凹曲線之列L4，配置有直徑較小之隔 開等距間隔之壓著部3 5，而形成有第1群之壓著部。該 第1群壓著部沿著上述列L4排列成一列，於排列於該列 -26- (23) (23)592675 之第1壓著部之兩側，形成有沿著上述列L4延伸之非壓 著領域，各壓著部3 5是獨立存在於非壓著領域內。 又，於上述第1群壓著部之內側，同樣地也沿著仿照 兩側緣部1 A、1 B之凹曲線之列L5，排列有直徑較小之隔 開等距間隔之壓著部3 6，藉此形成有第2群壓著部。該 壓著部3 6也於左右延伸有非壓著領域，各壓著部3 6是獨 立存在於非壓著領域內。 而，上於述第1群壓著部及第2群壓著部之間’用以 獨立兩群壓著部之非壓著領域3 7、3 7，沿著兩側緣部 1 A、1 B延伸於圓弧狀之帶狀地存在。 於該吸收薄片1 D，作用於兩側緣部1 A、1 B之變形 應力，也藉由構成沿著列L4之第1群壓著部之各個壓著 部3 5之排列被吸收、分散，再藉由構成沿著其內側之列 L5之第2群壓著部之各個壓著部3 6被吸收、分散。特別 是，於該實施形態，第1群各個壓著部3 5之於縱長方向 之排列周期，與第2群各個壓著部3 6之於縱長方向之排 列周期，是相差半周期。故爲於第1群壓著部3 5 3與壓著 部3 5之間，位有第2群壓著部3 6之關係。因此，超過第 1群壓著部欲朝向中央傳導之變形力，可藉由第2壓著部 再予以有效分散。 又前方固定部12及後方固定部13之構造，是與第i 圖所示之實施形態之吸收薄片1相同。 第9圖所示之吸收薄片1 E，於其右側緣部1 a之內側 形成有右側方固定部4 1 0，於左側緣部1 b之內側設置有 -27- (24) 左側方固定部4 1 1。該右側方固定部4 1 0及左側方固定部 4 1 1，是於第1圖之右側方固定部1 〇及左側方固定部1 1 沒有形成第2群壓著部，僅在沿著列L1之壓著部21及 23，形成排成一列之第1群壓著部，再於其內側形成規則 散佈之複數個壓著部22之構造。因此沒有設置區劃領 域。又，也沒有設置前方固定部及後方固定部。 於該吸收薄片1Ε，藉由沿著列L1形成之第1群壓著 部，如上述之各實施形態所示， 雖不如具備有第2群壓著部者之吸收分散變形應力之 效果顯著，但可成爲在吸收、分散作用於兩側緣部1 A、 1 B之變形應力之點上可發揮效果者。 又，吸收薄片之各層之構造亦有以下之變形。 例如，亦可爲上述表面薄片5僅1層且具備有液體之 吸收能力者。不過，爲了將壓著部之底面藉由熱壓花加工 予以平滑化作成薄膜面狀，上述表面薄片5必須包含熱可 塑性纖維。例如上述表面薄片5，爲水針不織布，作爲親 水性纖，可使用含有55質量％之維纖度爲1 .3 8dtex而纖 維長爲44mm之嫘縈纖維、30質量％之纖度爲1.43 dtex 而纖維長爲

cotton pad for weekday use, an absorbent sheet for menstrual blood, a urine-absorbent sheet for incontinent patients, and as a menstrual Absorbent articles such as sanitary absorbent napkins used in relatively small amounts, and particularly absorbent articles suitable for subsequent use in underwear. [Prior art] As thin absorbent articles, there are absorbent sheets known as cotton pads for weekdays that can absorb secretions or menstrual blood. This absorbent sheet is sandwiched between the pressure-sensitive pressure-sensitive adhesive layer and fixed to the inside of the lower part of the undergarment for wearing. The conventional absorbent sheet is generally a thin absorbent layer between a liquid-impervious back sheet and a surface sheet formed of a water-jet nonwoven fabric and the like, with a laminated absorbent paper and air-laminated pulp. structure. This kind of absorbent sheet is thin and the wearer can feel the same soft texture as the underwear. It must be easy to be distorted or deformed by the movement of the thigh in the wearing state, and the surface on the receiving side can be maintained at any time. Close to the state of the body excretion. [Summary of the Invention] [Technical Problems to be Solved by the Invention] However, compared with the normal use of sanitary napkins, the cotton pads of this type are less frequently exchanged in a day, and a piece of cotton pads used for a long time is The general situation. Therefore, due to the movement of the thighs, the deformation stress transmitted to the flat (2) cotton pad is likely to be twisted or deformed due to continuous action for a long time. If such creases or deformations become noticeable, problems such as a substantial reduction in surface area, a decrease in liquid absorption capacity, and a decrease in adhesion with the body excretory part, and the like are not easily captured. As a person focusing on such a deformation, for example, Japanese Unexamined Patent Publication No. 200 1 -2 76 1 26 discloses a cotton pad for daily use with an elastic layer interposed between a surface sheet and an absorbent body. In addition, in the cotton pad for weekdays, the surface sheet, the absorbent layer and the elastic layer, and the leakage-preventing sheet on the backside are formed by a plurality of compression portions formed on the inner side than the edges of both sides of the cotton pad for weekdays. Compressed and fixed. The cotton pad for weekdays uses the elastic force of the above-mentioned elastic layer to impart elastic restoring force to the distortion occurring in the wearing state to prevent the above-mentioned distortion from occurring, thereby improving the fit. However, even with the elastic layer as described above, if the deformation force is repeatedly applied from both sides while absorbing body fluid, the deformation force is directly transmitted to the central area, so it is difficult to avoid the use of cotton pads on weekdays. Large creases or deformations occur from the edges of the sides to the central area. It is also described in the above-mentioned publication that since the compression portions having a large area are formed at a wider interval than the edges of both sides of the cotton pads on weekdays, the creases or deformations are easily separated from the compression portions and the compression portions. Between the conduction to the central area. In addition, since each of the compression portions has a relatively large area, if the compression portion is a straight person, the compression portion may be blocked from a woman's sexual organs to cause discomfort, and it may easily become a person with a poor touch feeling. In order to solve the above-mentioned conventional problems, the present invention aims to provide a soft texture that does not hinder the whole, and the pressure from the thigh is not easily transmitted to the -6-(3) (3) 592675 central area, and it is not easy to produce distortion or crepe. Wrinkled and deformed absorbent articles. [Technical Means for Solving the Problem] The first invention of the present invention is directed to a plurality of sheets that are stacked together, and are provided with left and right edge portions extending in the lengthwise direction, a leading edge portion, and a trailing edge portion and are formed in a lengthwise manner. Type absorbent article, characterized in that: it crosses the center line of the transverse direction which divides the absorbent article in the longitudinal direction and extends within a range of a predetermined length in the longitudinal direction, at the edges of the above two sides A first group of a plurality of crimping portions is provided on the inner side, and the first group of a plurality of crimping portions are arranged at a predetermined interval and arranged in a row following the shape of the edge portions on the two sides, and are arranged in an array formed on the pressure crimping portions. Non-pressing areas extending along the arrangement direction of the plurality of pressing portions are respectively provided on both sides. When the absorbent article is worn next to the inner surface of the lower part of the panties, the pressure from the thighs acts on the edges of both sides. Since the crimping portions are arranged at intervals on the inner sides of the above-mentioned two edge portions to form an array, and the non-pressing areas are arranged on both sides of the crimping portions. The non-pressed part in the middle of the pressed part and the pressed part, the non-pressed area extending on both sides of the array, and the difference in rigidity or thickness between the individual pressed parts, in the pressed part, and the above non-pressed part Subtle deformations occur between the landing and non-pressed areas, but because the power of the pressure described above is absorbed by the slight deformations, it is not easy for the pressure from the outside to have much influence on the central area. Therefore, it is possible to prevent deformation such as large creases or twists from occurring in the center area. -7- (4) (4) 592675 As mentioned above, in order to absorb the pressure acting on the two side edges by the slight deformation of the inner sides of the two side edges, the interval between the adjacent pressure parts in the above arrangement is set to 0. 5 ~ 5 mm is ideal, and the area of the bottom surface of the above-mentioned crimping portion is within 0. It is preferably 25 mm2 or more and 6 mm2 or less. Also within the range of the area, it is preferable that at least a part of the first group is a circle, an oblong, or a polygonal pressing portion in which the bottom surface is arranged along the above-mentioned arrangement with a certain interval. However, the pressing portion is not limited to the above-mentioned shape, and may have various shapes such as a star shape and a moon shape. In the present invention, the edge portions on both sides are concavely curved, and the arrangement formed by the first group of pressing portions is also preferably concavely curved. At this time, the pressure from the thighs will act on the concave curved edge, but since the pressing parts are arranged along the concave curve, the pressure from the thighs can be pressed along the concave curve. The non-crimped portion between the portion and the crimped portion is absorbed. Furthermore, it is preferable that a plurality of second-group crimping portions are provided on the inner side of the first-group crimping portion so as to sandwich the non-pressing region. With this structure, when the deformation force acts toward the center in the first group of pressing portions forming the array, the second group of pressing portions can prevent the deformation from being conducted, and it is easier to prevent creases or distortions from occurring in the central area. The area of the second group of pressing parts is also 0. It is preferably 25 mm2 or more and 6 mm2 or less. The second invention of the present invention is an absorbent article in which a plurality of sheets are overlapped, and includes edge portions extending on the left and right sides in the lengthwise direction, and a front edge portion and a rear edge portion formed in an elongated shape. Features are: -8- (5) (5) 592675 Inside the edge of the two sides, a non-compressed area with a predetermined area surrounded by a plurality of crimping sections is provided. The longitudinal direction is divided into two center lines and extends over a range of a predetermined length in the longitudinal direction. A plurality of the above-mentioned division areas are arranged along the edges of both sides. In this absorbent article, when the pressure from the thighs is applied to the edge portions on both sides, the rigidity of each of the crimping portions and the non-crimping portion formed between the adjacent crimping portions and the crimping portions is caused by The slight deformation caused by the difference can not only prevent the stress from being transmitted in the central area, but also in the non-compressed area surrounded by a plurality of crimped parts. Since each sheet is elastically deformable in a limited area, This zoning area will act as a buffer against pressure from the outside, and deformations such as creases or distortions in the central area will become difficult to conduct. At this time, it is preferable that a plurality of the above-mentioned division areas arranged along the edges of both sides have the same shape and the same area. With this structure, the zoning area will play an equal buffering role, and the design will be better. At this time, the shape of the bottom surface surrounding at least a part of the plurality of pressing portions in the above zoning area is preferably a circle, an oblong, or a polygon, and the area of the bottom surface of the pressing portion is in the range of 0. 25mm2 to 6mm2 is ideal. In addition, if the minimum distance in the lateral direction between the pressing portion located inside the one side edge portion and the non-pressing area sandwiched by the pressing portion located inside the other side edge portion is 20 mm or more, The crimping part is difficult to give a female organ a stiff feeling. When considering the buffering effect described above, when the cotton pad is used as a weekday cotton pad for absorbing secretions, the minimum distance is preferably -9- (6) (6) 592675, preferably 20 to 35 mm. Furthermore, in the non-pressing area sandwiched between the pressing portion located inside the one side edge portion and the pressing portion located inside the other side edge portion, it appears on the outermost sheet in the lateral direction Those having alternately arranged ridges and ditches extending in the longitudinal direction are most suitable for the present invention. As described above, if the structure is provided with a ditch structure in at least the central area of the surface, the central area is soft and can reduce physical contact irritation. However, even if the central area is so soft, the pressure applied to the edges of both sides is easily absorbed by the above-mentioned crimping portion, so it is easy to prevent large creases and distortions from occurring in the soft central area.

It is also possible to form a large number of liquid-permeable holes in the spunbond nonwoven fabric. As shown in Fig. 1, in the first surface sheet 5 A, a ditch forming extending in the longitudinal direction is provided in a range of a predetermined width WA centered on the longitudinal centerline 〇y-〇y. Sphere 1 5. As shown in Figure 13-13 (10) in Figure 2, in the above-mentioned ditch forming area 15, the same as the ridge portion 15 A extending over the full length in the longitudinal direction is the same as the groove portion extending over the full length in the longitudinal direction. The lateral direction is repeatedly formed with a certain interval. The height of the ridge portion 1 5 A, that is, the size of the first surface sheet 5A minus the thickness of the first surface sheet 5A on the ridge forming area 15 is 0. In a range of 3 to 2 mm, the distance between the ridge portions 15A and the groove portion 15B is within a range of 1 to 3 mm. The wide size WA of the ditch forming area 15 is 15 to 35 mm. In the first surface sheet 5 A, the ditch forming area 15, by extending the entire length in the lengthwise direction in the central portion within a predetermined wide WA range, it can reduce the irritation of female sexual organs when they are in contact, and become an excellent wearer. . The second surface sheet 5B becomes the ditch forming area 16 in its entirety. As shown in Fig. 2 and Fig. 3, in the salt groove forming area 16 of the second surface sheet 5B, the ridge portion 16 A extending in the longitudinal direction and the groove portion 16 B extending in the longitudinal direction are also It is formed repeatedly at a certain interval in the transverse direction. The ideal range of the height dimension of the ridge portion 16 A in the ridge forming area 16 of the second surface sheet 5B mentioned above, and the ideal range of the distance between the ridge portion 16 A and the groove portion 16 B is from the first surface The ridge forming area of the sheet 5 A is the same as that of the field 15 A. As described above, by providing the ditch forming area 16 in the entirety of the second surface sheet 5B, even if the entire body portion 2 is made thin and the intermediate sheet 4 is made of a high-density structure, the cushioning property on the surface side can be improved. Further, by providing the ditch forming areas 15 and 16 on the first surface sheet 5A and the second surface sheet 5B, the central region of the absorption sheet 1 can be made soft -14- (11) (11) 592675. Part will become easy to follow the deformation of the lower part of the fit panties. Therefore, it will improve the close adherence of female sexual organs, and it will not be easy to feel discomfort when wearing the femoral palate. The forming of the above-mentioned ditch forming areas 15 and 16 is performed by combining a pair of rollers having unevenness corresponding to the shape of the ditch to supply the spunbond nonwoven fabric between the rollers heated to about 120. . By this heating and pinching, ridges and gullies are formed on the nonwoven fabric. As shown in Fig. 4 (A) (B), the right-side fixing portion 10 is formed by arranging pressing portions of three sizes. The crimping portion includes a first crimping portion 21 having a circular shape with a small diameter in a planar shape, a second crimping portion 22 having a circular shape having a slightly larger diameter than the first crimping portion 21, and a flat surface having a moon shape形 之 三 压 压 部 23。 The third pressing section 23. The first pressing portion 21, the second pressing portion 22, and the third pressing portion 23 'are formed by hot embossing. That is, 'on the outer surface of the back sheet 3', the blocking surface has a smooth roller. From the side of the first surface sheet 5 A, an embossing roller having protrusions corresponding to the above-mentioned pressing portion patterns is blocked. 2 Squeeze between the rollers heated above 120 ° C to perform the hot embossing process. 2 and 3 are sectional views of the first crimping portion 21 described above. As shown in the cross-sectional view, the bottom surface 21A of the first crimping portion 21 is flattened by the above-mentioned hot embossing. In addition, since the back sheet 3, the middle sheet 4 and the surface sheet 5 each contain a thermoplastic material, the above-mentioned bottom surface 2 1 A, the above-mentioned thermoplastic material is melted, so that it can be smoothed to the extent that there are no fiber irregularities, and the surface of the bottom surface 21A Roughly the same as the film surface -15- (12) (12) 592675 Smooth. In order to make the bottom surface 21A a smooth film surface as described above, it is desirable that the surface sheet 5 contains a thermoplastic material. However, if the bottom surface 2 1 A of the pressing portion is not restricted to a smooth film surface, the surface sheet 5 may not include a thermoplastic material. For example, when a non-heat-pressable surface sheet 5 made of cellulose fibers is used, a hot-melt adhesive is applied to the lower surface thereof and then the lower layer is subjected to heat embossing to form a high-rigidity pressure.着 部。 The Ministry. This is the same for the second crimping section 22 and the third crimping section 23, and the bottom surface 22A of the second crimping section 22 can also be rounded and smoothed. The bottom surface 23A of the third crimping section 23, Can also be made into a moon shape and smooth surface. As shown in Fig. 4 (A), a first group of a plurality of crimping portions are arranged along the concave column L 1 imitating the right edge portion 1 A on the right side fixing portion 10. In the first group of the plurality of crimping portions, a first crimping portion 21 and a third crimping portion 23 are regularly arranged. The line L 1 in which the first group of crimping portions are arranged is a concave curved shape similar to the right edge portion 1 A, and has a curvature radius of 120 to 300 mm. In addition, as shown in FIG. 3, the width from the right edge portion 1A to the edge of the bottom surface 21A of the first pressing portion 21 is a wide dimension, that is, the non-pressure between the right edge portion 1 A to the right side fixed portion 10. The wide size WB of the landing area is about 1 ~ 8mm. In the first group of crimping portions in this embodiment, three first crimping portions 21 and one third crimping portion 23 are arranged along the line L1, and are repeatedly spaced along the line L1. A pattern arranged at intervals. Further, on the right side fixing portion 10, inside the first group of pressing portions -16- (13) (13) 592675 L1, the second group of pressing portions are arranged along the column L 2 in the first group. There are two groups of crimping portions, and the first crimping portion 21 and the second crimping portion 22 are regularly arranged along the row L 2. The second group of crimping portions' in this embodiment are formed by regularly repeating five first crimping portions 21 and one second crimping portion 2 2 along the line L 2. The second crimping portion 22, which also constitutes the second group crimping portion, is adjacent to the third crimping portion 23, which constitutes the first group of crimping portions. The above-mentioned row L2 in which the second group of crimping portions are arranged is a sudden curve R 1 between the second crimping portion 22 and the second crimping portion 22 toward the longitudinal centerline 0 y _ 0y. In the shape repeated in the longitudinal direction, the first pressing portions 21 are arranged at regular intervals on the convex curve R 1. Further, the first crimped portion 21 and the third crimped portion 23 which are the first crimped portions arranged along the column L 1, and the second crimped portions arranged along the convex curve R 1. The area surrounded by the first crimping portion 21 and the second crimping portion 2 2 forms a zoning area 2 4. In this division area 24, the back sheet 3, the middle sheet 4, and the first surface sheet 5A and the second surface sheet 5B exist in a non-pressed state without being pressed by embossing. However, as described above, in the above-mentioned division area 24, the back sheet 3, the middle sheet 4, and the first surface sheet 5A and the second surface sheet 5B are respectively formed in a mesh shape, a comb shape, or a spiral shape. The pattern is applied by a hot-melt adhesive. In the row L2, the protrusion curve r 1 is formed by overlapping the protrusion curve r 1 in the longitudinal direction. Therefore, the plurality of the division areas 2 4 of the same area on the right side fixing portion 10 are along the side edge portion 1 a. Repeat settings. There are second crimping section 22 and third crimping section 23, zone area 24 and zoning area 24 between the division area 24 adjacent to -17 (14) (14) 592675, and become the sandwiching crimping section in the middle. The relationship formed by land abutment. The width dimension wc in the lateral direction of the bottoms of the first crimping part 21, the second crimping part 22, and the third crimping part 23 shown in FIG. 3 is the same as or less than the distance between the ridges 15A. Wc at 0. 5 ~ 2. The range of 5 mm is ideal, and the area of the bottom surface of the crimping part is within 0. The range of 2 5 to 6 mm2 is ideal. If the widthwise width of the crimping portion is within the above range and the area is within the above range, and the distance between the ridge portions is 15 A or less, the existence of the crimping portion is not easily felt by the skin. In the present invention, although the ridge portion 15 A and the groove portion 15 B are not prevented from being formed on the entire surface of the first surface sheet 5 A, in this case, as long as the lateral width of the pressing portion is within the above range, then Due to the existence of the crimping portion, the accuracy of flattening the ridge portion 15A becomes low, and the skin does not easily feel the existence of the crimping portion. The interval 5 of the first group of crimping sections along the column L 1 and the interval 6 of the second group of crimping sections along the column L 2 are located between the adjacent crimping sections along the above-mentioned column L 1. The size of the non-pressing portion 10A, and the size of the non-pressing portion 1 0B (5 to 0. About 5 to 5 mm is ideal. The distance Wd between the first group of crimping portions and the second group of crimping portions in the lateral direction is preferably 3 to 8 mm in the largest place, and the area of the above-mentioned zoning area 24 is preferably in the range of 15 to 50 mm2. As long as it is in this range, the elastic deformation force of the division area 24 makes it difficult for the forces acting on the side edge portions 1 A and 1 B to be transmitted to the central portion. Here, referring to the enlarged fourth figure (B), focusing on forming a plurality of crimping portions of the first group arranged along the column -18- (15) (15) 592675 L1, the crimping portions are as described above. It is arranged in a line along L 1, and at the same time, there is a non-crimped portion 10 A with a width of 5 between the crimped portions adjacent to the arrangement direction. On the left and right sides of the three first crimping portions 21 arranged along the column L1, along the arrangement direction of the three first crimping portions 21, there are extensions indicated by (i) and (Π) In the non-pressing area in the direction, the first pressing part 21 becomes an independent existence in the non-pressing area in the lateral direction, respectively. Similarly, when focusing on forming the plurality of crimping portions of the second group, as described above, the crimping portions are arranged in a row along the convex curve R 1 of the column L2, and exist between the crimping portions adjacent to the arrangement direction. There is a non-crimped portion 10B with a wide size 6. On the left and right sides of the five first pressing portions 21 arranged along the convex curve R1, there are extending along the arrangement direction of the five first pressing portions 21 to (iii) and (iv). In the non-pressed area in the direction shown, the first pressed part 21 in the second group also exists independently in the non-pressed area in the lateral direction. That is, in this embodiment, on both sides of any one of the plurality of pressing portions in the first group, a non-pressing area extending along the pressing portions is formed. Separate and independent in the crimping area, multiple crimping groups are separated separately. On the other hand, the group of independent pressing portions is arranged intermittently at plural places along the above-mentioned column L 1. This is also the same for the plurality of pressing portions in the second group along the above-mentioned column L2. The arrangement of the pressing portions on the left fixing portion 11 is symmetrical to the arrangement of the pressing portions on the right fixing portion 10. As shown in Fig. 1, the second group of the first fixed portion 10 is -19- (16) (16) 592675 the landing portion 2 1 and the second group of the left fixed portion 1 1 is the first The interval between the crimping portions 21 is We, and it is the narrowest at the position of the lateral centerline Ox-Ox. The narrowest interval We is 20 to 35 mm. If it is not within the above range, the respective crimping portions of the right side fixing portion 10 and the left side fixing portion 11 may be easily blocked against the labia, which may damage the wearing feeling. If it exceeds the above range, the distance between the first group of crimping portions arranged along the column L1 and the second group of crimping portions arranged along the L2 will be narrowed, and the area of the zoning area 24 will be too narrow. 24 can not get a sufficient buffer effect. As shown in Fig. 1, the first pressing portion 21 and the second pressing portion 22 are regularly arranged on the front fixing portion 12 along the line of the convex curve imitating the front edge portion 1c of the absorbent sheet 1. The rear fixing portion 13 is symmetrical to the front fixing portion 12 described above. Similarly, the first crimping portion 21 and the second crimping portion 22 are also regularly arranged. The ideal wide size Wc and area on the bottom surface of each pressing portion provided on the front fixing portion 12 and the rear fixing portion 13, and the ideal interval size in the arrangement direction (5 and so on, are the same as the right side fixing portion 1 above). 〇 It is the same as the left side fixing portion Π. When using the absorbent sheet 1, the release sheet 7 on the back side is peeled off, and the pressure-sensitive adhesive layer 6 is then fixed on the inner side of the lower part of the panty and worn. 1. Because the edges 1A and 1B on both sides are concavely curved, the concave curves of the edges 1A and 1B on the sides of the underwear will be approximately the same as the edges of the opening of the underwear when they are mounted on the lower part of the panty. If the absorbent sheet 1 is worn in the panty, the lower part of the panty will be deformed due to the movement of the femoral crotch or the tightening force of the thigh. No -20- (17) Yes, because the absorbent sheet 2 The whole is thin, and the back sheet 3, the middle sheet 4 and the surface sheet 5 are formed of a soft material. Therefore, the entire absorption sheet 1 can easily follow the deformation of the lower part of the panty that fits the panties, and it is not easy to cause discomfort in the crotch region. Especially It's all in the second surface sheet 5B A ditch forming area 16 is provided, and a strip-shaped ditch forming area 15 is formed at the center of the first surface sheet 5A. Therefore, the center portion of the absorbent sheet 1 is soft, and the center area becomes easy to follow the matching underwear. Deformation. Since the first surface sheet 5 A in the ditch forming area 15 is to block the female sexual organs, the female sexual organs are soft to the touch. However, if the entire absorbent sheet is soft, it will come from the thighs. The tight bundle pressure acting on the edges 1 A and LB on both sides will first be deformed on the edges 1 A and 1 B on the sides. This deformation force will be easily transmitted to the central area of the absorbent sheet. As a result, there will be There may be large distortion or creases in the soft central area where the ditch forming area is provided. However, the absorbent sheet 1 in this embodiment is arranged along a line L 1 imitating the edge portions 1 A and 1 B on both sides. The first crimping portion 21 and the third crimping portion 23 with a small number of moderately spaced intervals are opened, and as shown in FIG. 4 (B), the plurality of first crimping portions 21 along L1 are in a non-pressed state. Independent areas in the field, so with the tight restraint from the thighs If the deformation force acts on the edge portion of the lower part of the panty and the above-mentioned side edge portions 1 A and 1 B at the same time, the pressing portions 2 1 and 23 existing along the line L 1 and the non-positioned portions therebetween. The difference in rigidity and thickness between the crimping portions 10A, and further, by a plurality of crimping portions 2 arranged along the column L1;! And as shown in (i) (ii) on both sides The difference in rigidity and thickness between the extended non-pressed areas will cause slight deformation between the pressed -21-(18) contact areas 2 1, 2 3 and the non-pressed areas 10A and the aforementioned non-pressed areas. As a result, the deformation pressure can be absorbed and dispersed. Therefore, the deformation force acting on the edge portions 1 A and 1 B on both sides becomes difficult to be directly transmitted to the central area of the absorption sheet 1 and can be prevented by the force from the side. Large twists or creases occur in the central area. As described above, in order to make use of the difference in rigidity and thickness of the crimping portions 21, 23 and the non-crimping portion 10A, and a plurality of crimping portions 21 arranged along the line L 1 and on both sides thereof, such as (I) (ii) The rigidity difference and thickness difference of the non-pressing area extending as shown in (ii). The force used to disperse the deformation force from the side must be the thickness of the absorbent sheet on the bottom surface of the pressing section, and the non-pressing It is preferable that the difference between the thicknesses of the landing portion 10A and the absorbent sheet in the non-pressed area is at least 0.2 mm. The upper limit of the difference is not particularly specified, but in order to make a thin absorbent sheet, the thickness of the entire absorbent sheet is preferably about 3 mm, so the ideal range of the thickness difference is 0. 2 to 3 mm 〇 There are intermittent edges along the right side fixing part 10 and the left side fixing part of the absorption sheet 1 above the first group of pressing parts arranged along the above-mentioned column L1. The second group of crimping portions arranged in the row L2. Therefore, when the deformation stress of the first group of crimping portions is not applied to the column L2, the crimping portions 21, 22 constituting the second group, and the non-crimping portion 1 OB located between the crimping portions, In addition, the non-pressing area extending as shown in (iii) (iv) on both sides of the pressing portion 21 along the line L2 has the same function of dispersing deformation energy as the above, so it can effectively prevent The deformation force is transmitted to the central area. -22- (19) (19) 592675 Furthermore, since the zoning area 24 'surrounded by the intermittent crimping portion is arranged along the edges 1A and 1B on both sides, it acts on the edges 1 on both sides The large creases such as A and 1 B will be absorbed and alleviated in the aforementioned zoning area 24. That is, the above-mentioned zoning areas 24 are separated from each other by a predetermined area, and the inner back sheet 3, the middle sheet 4, and the front sheet 5 are in a non-pressed overlapping state. Therefore, when the edge portions 1 A and 1 B on both sides are subjected to a large deformation force, the above-mentioned sheets are bent within a limited range within each division area 24, and then the elastic restoring force is exerted. By bending and elastic restoring force in this limited area, it is possible to prevent the deformation force acting on the edge portions 1 A ′ 1 B from being transmitted to the central area. In addition, the first group of crimping portions arranged along the column L1 and the second group of crimping portions arranged along the column L2 are smaller and arranged at intervals, because of the lateral width of each crimping portion. The width Wc is preferably smaller than the arrangement pitch of the ridge portion 15 A or the ridge portion 16 A. Therefore, each pressing portion does not give the body a rigid feeling. In addition, the smaller crimping portions are arranged in a row along the side edge portions 1 A and 1 B and are arranged intermittently, and there are non-pressing areas on the two sides. The above arrangement is independent of the non-pressing areas. In the field, the absorption sheet 1 near the edges 1 A, 1 B on both sides is not very rigid, and cannot prevent the edges 1 A, 1 B on both sides of the absorption sheet 1 from bending along the crotch region. Deformation. Therefore, the absorbent sheet 1 does not give a stiff feeling to the crotch region of the body. This will become clearer when comparing it with -23- (20) where a strip-shaped crimping portion extending linearly along the above-mentioned column L 1 or a knurling pattern shape of a predetermined width extending linearly is formed. Already. Those who have the above-mentioned linear crimping portion or knurling pattern crimping portion have edges 1A and 1B on both sides that are not easily bent and become a person who imparts a stiff feeling to the body. However, in the absorbent sheet 1 of the above embodiment, As described above, it has the effect of dispersing the tightening force acting on the edges 1 A and 1 B on both sides, and does not give the body a sense of stiffness. In addition, the absorbent sheet 1 is provided with a front fixing portion 12 and a rear fixing portion 13 inside the front edge portion 1 c and the rear edge portion 1 d, and the first pressing portions are formed with a certain interval therebetween. 2 1 and second crimping portion 22. Therefore, in the vicinity of the leading edge portion 1 c and the trailing edge portion 1 d, the absorbent sheet 1 does not give the body a stiff feeling, and acts on the crease generating force or twisting force of the underwear of the leading edge portion 1 c and the trailing edge portion 1 d. It will be absorbed and dispersed like the above. Hereinafter, a modification example of the arrangement pattern of each pressing portion will be described. In the following modification examples, the laminated sheet structure, ditch structure, etc. other than the pattern of the crimping portion, and various other ideal conditions are the same as those of the absorbent sheet 1 shown in Fig. 1 above. The absorbent sheet 1 A of the embodiment shown in FIG. 5 has the same size and arrangement pattern of the pressing portions on the right fixing portion 10 and the left fixing portion 11 as the absorbent sheet 1 shown in FIG. 1. . However, in FIG. 5, the pressing portions of the front fixing portion 12 and the rear fixing portion 13 are not provided. In addition, the ditch forming area 15 of the first surface sheet 5 A may be provided in Fig. 5 or not provided. Since the absorbent sheet 1 A shown in FIG. 5 is not in the pressing portion of the front fixing portion 12 and the rear fixing portion 13, it can be pressed by the fixing portions 10 and 11 formed on both side surfaces. The pattern of the part absorbs and disperses and acts on the absorption -24- (21) (21) 592675 The tightening force of the edges 1 A and 1 B on the sides of the sheet 1 can effectively prevent large creases or distortions from occurring in the absorption. The central area of the sheet. In the absorbent sheet 1 B of the embodiment shown in Fig. 6, the right-side fixing portion 1 1 0 and the left-side fixing portion 1 1 1 are left-right symmetrically sandwiched with the longitudinal centerline 0y-〇y. Only the left side fixing portion 111 will be described. In this fixing portion 111, the dotted crimping portions 25 are formed in two rows in a wavy pattern, and the wavy patterns in each row cross each other to form the crimping formed by the dotted line. Non-pressed zoning areas surrounded by Departments 2 5 2 6. The plurality of division areas 2 6 are arranged along the left edge portion 丨 b in a manner similar to the left edge portion 1 B, and the area of each division area 2 6 is the same. The adjacent zoning area 26 and the zoning area 26 are adjacent to each other with the pressing portion 25 interposed therebetween. In this embodiment, the ideal range of the area of the division area 26 is also the same as that of the division area 24 shown in FIG. 1. Further, at a position close to the left edge 邰 1 B, two point-shaped crimping portions 27 are formed at the crossing positions of the dotted-line crimping portions 25. Therefore, when the dotted-line crimping portion 25 and the line L 3 connecting the dot-shaped crimping portion 27 are set, the crimping portion 25 and the crimping portion 27 located on the L 3 and The crimping portions located in the row L 1 shown in FIG. 4 also constitute the first group of crimping portions. In addition, a structure in which the second group of crimping portions are arranged on the inside of the first group of crimping portions arranged along L 3 is sandwiched by the above-mentioned division area 26. Therefore, the absorbent sheet 1 B can also absorb and disperse the deformation stress acting on the edge portions 1 A and 1 B on both sides, and prevent large creases or distortions from occurring in the central area. -25- (22) (22) 592675 Also shown in the absorbent sheet 1 b shown in FIG. 6, a front fixing portion 1 i 2 is formed inside the front edge portion 1 c, and is formed inside the rear edge portion 丨 d. There are rear fixing parts Π 3. The fixed portions 丨 2 and 〖〗 3 are formed along the curve imitating the leading edge portion 1 c and the trailing edge portion 1 d, and the first pressing portion 21 and the second pressing portion 22 are formed at intervals. The absorbing and dispersing function of the deforming force is the same as that of the absorbing sheet 1 described above. The absorbent sheet 1 c shown in FIG. 7 includes a right-side fixing portion 2 1 0 and a left-side fixing portion 2 1 1 and is provided with a wavy crimping portion 2 8 ′ formed by the dotted line. The enclosing part becomes a non-pressing zoning area. In the right fixed part 2 and the left fixed part 2 丨, there are two divided areas 2 9 with the same area along the edges 1 A and 1 B. Also, a straight line is formed along the front edge portion 1 c and the rear edge portion 1 d on the inner side of the front edge portion 1 c and the rear edge portion 1 d on the front fixing portion 1 1 2 and the rear fixing portion 2 1 3. Crimping section 3 1, 31. In this absorbent sheet 1 C, similar to the above, it is also possible to absorb and disperse the deformation forces' acting on the edges 1 A, 1 B on both sides by the intermittent crimping portion 28 and the zoning area 29. Those with soft edges near the edges 1 A, 1 B on both sides. In the absorbent sheet 1 D shown in FIG. 8, a right side fixing portion 3 1 0 is formed inside the right edge portion 1 a, and a left side fixing portion 3 1 1 is formed inside the left edge portion 1 B. On both sides of the fixed portion 3〗 〇, 3〗, along the line L4 imitating the concave curve of the edge portions 1 A, 1 B on both sides, the crimping portions 3 5 with smaller diameters are arranged at equal intervals. A crimping portion of the first group is formed. The first group of crimped portions are arranged in a row along the above-mentioned column L4, and on both sides of the first crimped portion arranged in the column -26- (23) (23) 592675, there are formed extending along the above-mentioned column L4. In the non-pressing area, each of the pressing portions 35 exists independently in the non-pressing area. In addition, inside the first group of crimping portions, similarly, the crimping portions having smaller diameters at equal intervals are arranged along the line L5 that imitates the concave curve of the edge portions 1 A and 1 B on both sides. 36, whereby a second group of crimping portions is formed. This pressing portion 36 also extends in the non-pressing area on the left and right, and each pressing portion 36 is independently present in the non-pressing area. In the above, between the first group of crimped portions and the second group of crimped portions, the non-pressed areas 3 7, 3, which are used to separate the two groups of crimped portions, are along the edges 1 A, 1 on both sides. B extends in an arc-shaped band. In this absorbent sheet 1 D, the deformation stress acting on the edge portions 1 A and 1 B on both sides is also absorbed and dispersed by the arrangement of each of the pressing portions 35 forming the first group of pressing portions along the row L4. Then, each of the pressing portions 36 constituting the second group of pressing portions along the inner row L5 is absorbed and dispersed. In particular, in this embodiment, the arrangement period of the respective crimping portions 35 in the first group in the longitudinal direction is different from the arrangement period of the respective crimping portions 35 in the second group in the longitudinal direction by a half cycle. Therefore, the relationship between the second group of crimping portions 3 5 3 and the first group of crimping portions 3 5 3 is 3 6. Therefore, the deformation force exceeding the first group of pressing portions to be transmitted toward the center can be effectively dispersed by the second pressing portion. The structures of the front fixing portion 12 and the rear fixing portion 13 are the same as the absorbent sheet 1 of the embodiment shown in FIG. I. In the absorbent sheet 1 E shown in FIG. 9, a right-side fixing portion 4 1 0 is formed on the inner side of the right edge portion 1 a, and a left-side fixing portion is provided on the inner side of the left edge portion 1 b. 4 1 1. The right-side fixing portion 4 1 0 and the left-side fixing portion 4 1 1 are the right-side fixing portion 10 and the left-side fixing portion 1 1 in FIG. 1, and the second group of crimping portions are not formed. The crimping portions 21 and 23 of L1 form a first group of crimping portions arranged in a row, and a structure in which a plurality of crimping portions 22 are regularly dispersed is formed inside. Therefore, no zoning area is set. Moreover, neither the front fixing part nor the rear fixing part was provided. As shown in each of the above embodiments, the first group of pressing portions formed along the line L1 in the absorbent sheet 1E is not as effective as the one having the second group of pressing portions in absorbing and dispersing deformation stress. However, it can be effective in that it can absorb and disperse the deformation stress acting on the edge portions 1 A and 1 B on both sides. The structure of each layer of the absorbent sheet also has the following deformations. For example, the surface sheet 5 may have only one layer and have a liquid-absorbing ability. However, in order to smooth the bottom surface of the crimping portion into a film surface shape by heat embossing, the surface sheet 5 must contain thermoplastic fibers. For example, the above-mentioned surface sheet 5 is a water needle nonwoven fabric, and as the hydrophilic fiber, a dimensional fineness containing 55% by mass can be used. 3 8 dtex with a fiber length of 44 mm, and a fineness of 30% by mass is 1. 43 dtex polyester fiber with a fiber length of 38mm and a fineness of 5% by mass is 1. 65 dtex polypropylene fiber with a fiber length of 45mm 1 has a basis weight of about 38 g / m2. In addition, as described above, if the bottom of the pressing portion is not restricted to a thin film surface, a cellulose fiber such as cotton or paper pulp may be used as the main body, or a surface composed of only cellulose fibers may be used. Sheet-28- (25) (25) 592675 At this time, the 'intermediate sheet 4 is made of a core-sheath composite synthetic fiber with a polyester core and a polyethylene sheath, and a basis weight of about 25 g / m2 It is formed by air-through non-woven fabric. The intermediate sheet 4 is considered to be used for absorbing liquid, so it is better to regard it as a buffer layer and exert the function of reducing the pressure on the skin. Alternatively, the back sheet 3, the intermediate sheet 4, and the front sheet 5 may be formed of a hydrolyzable material or a biodegradable material. This allows the absorbent sheet to be discarded into a flush toilet after use. At this time, the back sheet 3 may be made of rayon fiber, cotton fiber, biodegradable resin fiber, etc. having a fiber length of 1 to 10 mm, and a water-jet non-woven fabric or paper using a water-soluble adhesive such as PVA resin. form. Or it can be used in the above non-woven fabric or paper coating with PVA, water-decomposable ester urethane, etc., or polylactic acid, polybutyl succinate, polybutyric acid (Poly Hydroxy Butyrate; PHB) and other biodegradable resin films. The intermediate sheet 4 can be a water-jet needle-woven fabric or paper formed by a fiber with a fiber length of 1 mm to 10 mm, such as woven fibers, cotton fibers, and biodegradable resin fibers, or polyvinyl alcohol (PVA) can be added here. Resins, etc. are used as adhesives, or air-laid non-woven fabrics that use chemical-bonding (chemical-bonding) using a small amount of water-soluble materials such as acrylate or pVA as adhesives. The surface sheet 5 may be made of the above-mentioned hydrolyzable water-jet nonwoven fabric. Alternatively, it may be one in which a large number of liquid-permeable holes are formed in the water-soluble resin film. -29- (26) (26) 592675 Also absorbs the size of the sheet, the length of the centerline 〇y-〇y in the longitudinal direction is 604 40111111, and the width of the centerline 〇χ-〇χ in the transverse direction is 45 ~ 65mm. [Effects of the invention] As described above, the absorbent article of the present invention does not impair the overall softness, and can prevent large creases or distortions from occurring in the central area. It can ensure that the area of the surface receiving liquid is wide at any time, which is a good Those with good adhesion to the excretory part of the body. Since it is soft as a whole, it is less likely to give the body stiffness from the side edges. Furthermore, it is particularly suitable for thin absorbent articles such as sheets for absorbing secretions.
