200913965 九、發明說明 【發明所屬之技術領域】 本發明是有關一種吸收性物品及其製造方法。特別是 有關一種密著性及防漏性優的吸收性物品及其製造方法。 【先前技術】 自以往，據知供吸收經血等之排泄物的吸收性物品， 例如有生理用衛生棉、衛生護墊、尿片等。該等之吸收性 物品具有：吸收保持全部經血等的吸收體、和配置在吸收 性物品的肌膚抵接面的透液性的表面薄片、和配置在吸收 性物品的著衣抵接面的不透液性的背面薄片，例如以黏著 在內褲的狀態穿著使用。 可是，如上述的吸收性物品，爲了確實捕捉來自穿用 者之排泄部的排泄物’希望使吸收體的吸收部密貼在排泄 部使用。例如，如果穿用者之排泄部與吸收性物品之間產 生間隙，溢出吸收性物品之表面薄片的排泄物沿著表面薄 片流出，藉此產生排泄物往吸收性物品的側方或臀部方向 外漏，有弄髒內褲或衣服之虞。 尤其在生理用衛生棉固定在內褲穿用的情況下，以此 狀態移動身體的話’在內褲與排泄物之間容易產生相對性 的位移’該位移爲造成橫漏的原因。又，例如由於生理用 衛生棉通常是處於與內褲一同夾持在穿用者的大腿部之間 的狀態，因此由穿用者的大腿部受到橫向的壓縮力，產生 壓縮變形。藉此’因吸收體的變形狀態，在穿用者的排泄 -4- 200913965 部與生理用衛生棉之間形成間隙，如上述有弄髒內褲或衣 服之虞。 對此’例如日本特開平第09- 1 08262號公報（以下稱專 利文獻1)中，揭示連續的擠壓處理表面薄片與吸收體，藉 此形成一對擠壓溝，將各擠壓溝分別設置在生理用衛生棉 的長邊方向，藉此防止由吸收體的扭曲所產生的排泄物等 橫漏的生理用衛生棉。 曰本專利文獻1所記載的生理用衛生棉，例如將一對 擠壓溝配置成夾介設置在生理用衛生棉之寬度方向的略中 心部的芯部。該擠壓溝是相對式的接連著密度高的擠壓部 與密度低的擠壓部，以溝狀形成在生理用衛生棉的肌膚抵 接面側。藉此’自穿用者的大腿部承受橫向的壓縮力，即 使在吸收體的略中央部產生扭曲，也可防止該扭曲延伸到 周緣部。如此一來，經血等沿著該扭曲流出，防止從周緣 部橫漏。 又’例如在日本特開平1 0-993 72號公報（以下稱日本 專利文獻2)中揭示一種從肌膚抵接面側進行壓花加工，設 有形成朝穿用者之肌膚抵接面側彎曲的第1可撓軸、和從 著衣抵接面側進行壓花加工，形成朝著衣抵接面側彎曲的 第2可撓軸，藉此使吸收體朝肌膚抵接面變形提昇密著性 的吸收性物品。 曰本專利文獻2所揭示的吸收性物品，分別在吸收性 物品的肌膚抵接面側及著衣抵接面側設置第1及第2可撓 軸。藉此，即使在自穿用者的大腿部承受橫向之壓縮力的 -5- 200913965 情形下，由於吸收體分別在肌膚抵接面側及著衣抵接面側 易於彎曲，因此易變形成所要的形狀。 【發明內容】 〔發明欲解決之課題〕 但是’日本專利文獻1所揭示的生理用衛生棉，例如 擠壓溝是配置在芯部之厚度方向的略中央部至芯部的背面 之間。因而’自穿用者的大腿部朝寬度方向施加壓縮力的 情形下，從擠壓溝傳遞到芯部的力，會從吸收體之厚度方 向的肌膚抵接面側擴散至著衣抵接面側的各個方向。藉此 ，芯部有朝各個方向彎曲之虞，有無法經常得到穩定之變 形形態的問題。 又，日本專利文獻2所揭示的吸收性物品，由於在厚 度方向，第1可撓軸是形成在比吸收體的著衣抵接面側更 靠近肌膚抵接面側，因此在從穿用者的大腿部朝寛度方向 施加壓縮力的情形下，從第1可撓軸傳遞的力，會擴散到 吸收性物品之厚度方向的肌膚抵接面側及著衣抵接面側等 的各個方向。且，由於也在第2可撓軸的肌膚抵接面側形 成溝，因此即使在第2可撓軸的穿衣抵接面側，力作用於 穿衣抵接面側方向，仍有無法得到朝肌膚抵接面側穩定變 形之虞。 本發明是有鑑於如上課題所完成的發明，目的在於提 供一種確保穩定的變形形態，藉此提昇對肌膚的密著性， 減輕體液等漏出的吸收性物品。 -6 - 200913965 本發明人等，爲了達成上述目的’在吸收性物 既的擠壓溝，在該擠壓溝的著衣抵接面側之面的兩 既定的空間部，藉此發現能有效的使吸收體變形， 成本發明。具體上是提供如下的吸收性物品。 (1) 一種吸收性物品，係爲具備：配置在肌膚抵

. 全體 根據本發明之第1實施形態的生理用衛生棉1 ’針對 本發明之吸收性物品的整體構造做說明。 如第1圖至第3B圖所示’有關本發明之第1實施形 態的吸收性物品的生理用衛生棉1具備：設置在穿用者的 肌膚抵接面側，構成表面層的透液性的表面薄片2、和設 置在穿用者的著衣抵接面側，構成背面層的不透液性的背 面薄片3、和被包覆在拭紙7，構成吸收層的保液性的吸 收體4。在背面薄片3的著衣抵接面側設有黏著部8’在 該黏著部8，生理用衛生棉1是與穿用者的內褲等黏固。 更在第1實施形態中，生理用衛生棉1具備：配置在表面 薄片2與吸收體4之間的透液性的中間薄片5、和構成表 面層之一部分的側面薄片6、和生理用衛生棉1之寬度方 向（WD)延伸的側翼Wl、W2。 又，生理用衛生棉1具備：由表面薄片2的肌膚抵接 面側向著背面薄片3形成凹狀的擠壓溝部的擠壓溝1 1。生 -11 - 200913965 理用衛生棉1藉由該擠壓溝1 1將吸收體4劃分成芯部40 與側部4 1。又，在擠壓溝1 1的著衣抵接面側，形成背溝 部的突出部15。在夾著突出部15的兩側設有由著衣抵接 面側向著肌膚抵接面側形成凸狀的空間部1 6。 1-2.表面薄片等 表面薄片2使用時被配置在穿用者之身體側的同時抵 接在排泄部。表面薄片2可整面爲透液性，也可一部分爲 透液性。又，可以一片的薄片構件所構成，也可接合複數 片薄片構件所構成。在本實施形態中，表面薄片2係在生 理用衛生棉1的寬度方向（WD)之略中央部具備透液性區域 ，且寬度方向（WD)的端部側以不透液性的側面薄片6覆蓋 〇 中間薄片5係使滲透表面薄片2的排泄物滲透到吸收 體4的同時，也作爲使用時的緩衝作用。吸收體4被包覆 在拭紙7，在生理用衛生棉1的寬度方向（WD)的略中央部 具備略橢圓形的芯部40。芯部40是藉由擠壓溝11被圍住 的區域。在芯部40的寬度方向（WD)的兩側形成有側部41 。芯部40與側部4 1是藉由擠壓溝1 1所劃分。背面薄片3 係使用不透液性的薄片構件，藉此防止保持在吸收體4的 排泄物等滲漏到穿用者的著衣抵接面側。 1-3.擠壓溝及空間部 擠壓溝1 1是以夾持芯部4 0的方式，設置成向著生理 -12- 200913965 用衛生棉1的長邊方向（LD)延伸。具體上，如第3A圖及 第3B圖所示，擠壓溝11具備：因高擠壓形成的凹部12 、和因低擠壓形成的凸部1 3，藉由各別連續擠壓高擠壓與 低擠壓所形成。 生理用衛生棉1係在擠壓溝11的背側，總之，在著 衣抵接面側，具備比芯部40的著衣抵接面側的背面42更 突出於著衣抵接面側的突出部1 5。在夾著突出部1 5的兩 側設有由著衣抵接面側向著肌膚抵接面側形成凸狀的空間 部16。 在本實施形態中，空間部1 6是以夾著突出部1 5的方 式形成在其兩側，且在吸收體4的著衣抵接面側，形成由 著衣抵接面側向著肌膚抵接面側凸出的凸狀。空間部1 6 的頂部，例如以較芯部40的背面42高2mm設置在肌膚 抵接面側的方式所形成。換言之，以形成在擠壓溝1 1之 底部的凹部1 2與空間部1 6的頂部之吸收體4的厚度方向 (TD)的高度差爲2mm的方式形成。理想上舉例表示，形 成在擠壓溝1 1之底部的凹部1 2與空間部1 6的頂部之吸 收體4的厚度方向（TD)的高度差是0.5〜10mm的範圍。只 要凹部1 2與空間部1 6的頂部之吸收體4的厚度方向（TD) 的高度差是0.5〜l〇mm的範圍，突出部15就更容易深入 形成在芯部40之著衣抵接面側的空間部1 6。 再者，在本實施形態中，雖然空間部1 6是以夾著突 出部1 5的方式設置在其兩側，但例如第4圖所示，也可 以只設置在芯部40側。空間部1 6是設置在芯部40側， -13- 200913965 藉此突出部1 5就可在空間部1 6彎折。換言之，可作用成 透過空間部1 6讓突出部1 5朝生理用衛生棉1的寬度方向 (WD)的中央部側傾倒。藉此就能確保突出部1 5已穩定的 變形形態與芯部40已穩定的變形形態，且能提昇對肌膚 的密著性。 擠壓溝11具備藉由利用後述之壓花裝置的嚙合所形 成的一對壁部1 4。壁部14例如將表面薄片2及吸收體4 朝生理用衛生棉1的厚度方向（TD)擠壓時，在生理用衛生 棉1的厚度方向（TD)的略中央產生強烈拉伸應力，藉由該 拉伸應力使吸收體4形成拉伸。而且，已被拉伸的吸收體 4的壁部1 4，係在該略中央形成低密度。該低密度部分， 係可抑制在芯部40吸收排泄物的情況下，由高密度部分 所傳來的排泄物擴散。 雖然擠壓溝1 1是例如藉由分別自肌膚抵接面側及著 衣抵接面側連續的擠壓表面薄片2及吸收體4所形成，但 本發明並不限於此。例如第5圖所示，亦可藉由分別自肌 膚抵接面側及著衣抵接面側只連續的擠壓吸收體4，形成 擠壓溝1 1。只在吸收體4形成擠壓溝1 1的情形下，由於 表面薄片2不會因擠壓而按壓吸收體4，因此吸收體4易 變形。又，亦可藉由分別自肌膚抵接面側及著衣抵接面側 連續的擠壓中間薄片5及吸收體4，形成擠壓溝1 1。例如 在分別自肌膚抵接面側及著衣抵接面側連續的擠壓利用合 成樹脂纖維等形成的中間薄片5與吸收體4的情形下，擠 壓溝Π爲形成易於保持突出著衣抵接面側的形狀。 -14- 200913965 擠壓溝11亦可在凹部12設置開口 17°藉由設置該開 口 1 7，可讓從表面薄片2傳過來的排泄物，掉落到設置在 芯部4 0之下層的著衣抵接面側的背面薄片3 ’讓排泄物掉 落到背面薄片3，就能抑制排泄物擴散到包含表面薄片2 的表面層。又，亦可在側壁部1 4設置開口 1 8。在此情形 下，亦同樣的，可讓從表面薄片2傳過來的排泄物’掉落 到設置在芯部4 0之下層的著衣抵接面側的背面薄片3。再 者，開口 1 8在擠壓時，以側壁部不會斷開之程度的大小 爲宜。 又，在本實施形態中，雖在相當於擠壓溝11之背面 的突出部1 5之位置的全部設有黏著部8 ’但本發明並不限 於此。至少在相當於突出部1 5之一部分的位置設有黏著 部8即可。 在本實施形態中，雖然在背面薄片3，藉由將防止偏 移用的黏著部8配置在擠壓溝1 1的著衣抵接面側，形成 不妨礙朝芯部40之肌膚抵接面側變形成凸狀，但本發明 並不限於此。例如，亦可在背面薄片3的著衣抵接面側， 以包含生理用衛生棉1之長邊方向（LD)之中心的狀態來設 置黏著部8。藉此，突出部！ 5可藉由接合吸收體4與背面 薄片3的熱熔膠8a比芯部40更經常的往著衣抵接面側配 置的同時’芯部40就能連同與芯部4〇接合的內褲70 — 起變形成凸狀。 又’吸收體4與背面薄片3的熱熔膠8a，亦可能離開 背面薄片3的接合著芯部4〇的背面42。具體上，至少接 -15- 200913965 合著擠壓溝11的背面與背面薄片3即可。藉此’由穿用 者的大腿部朝寬度方向（W D )施加壓縮力的情形下’背面薄 片3與芯部40的背面42可分開，形成既定的空間28 ’藉 由突出部1 5潛入到空間2 8，芯部4 0就能穩定的變形。 像這樣，生理用衛生棉1藉由設置擠壓溝1 1及空間 部1 6 ’芯部4 0就能在肌膚抵接面側變形成穩定的凸狀。 例如由穿用者的大腿部施加壓縮力的情形下，朝第6 A圖 所示的箭頭方向，施加壓縮力。此時，壓縮力會通過擠壓 溝1 1 ’傳遞到芯部40。在此，突出部1 5，如第6B圖所 示’於由空間部1 6是設置其兩側，因此會朝芯部4 0的背 面42側變形移動。具體上，突出部1 5，以潛入到形成在 突出部1 5與相鄰的芯部40的背面42之間的空間部1 6的 方式移動。以潛入方式移動的突出部15，係以自芯部40 的背面42按壓在芯部40的方式更進一步傳遞壓縮力。藉 此，芯部40是變形成突出肌膚抵接面側，密著於穿用者 的排泄部。 又，生理用衛生棉1，如第7A圖及第7B圖所示，在 擠壓溝1 1的著衣抵接面側，亦即突出部1 5，與內褲70固 定，藉此例如擠壓溝1 1能位在比芯部40更靠近著衣抵接 面側，因此芯部40能變形成穩定的凸狀。 又，生理用衛生棉1 ’係以折入到內褲7 〇之著衣抵接 面側，使該側翼W1、W2接著’藉此例如自穿用者的大腿 部朝寬度方向（WD)施加壓縮力的情形下，由於朝側部4 1 之厚度方向（T D )的移動受到限制’因此突出部1 5變得很 -16- 200913965 容易潛入空間部1 6，能穩定的變形。 2 .其他實施形態 採用第8圖至1 3圖’針對其他實施形態做說明。再 者，在以上實施形態中，未特別說明的部分’與第1實施 形態相同，附於圖面的標號也與第1實施形態相同的情形 下，附上相同標號。 2-1.第2實施形態 採用第8圖說明第2實施形態的生理用衛生棉1 A。 於第8圖中，爲了易於理解本發明的特徵，圖面僅爲表示 生理用衛生棉1A之擠壓溝的部分放大圖。如第8圖所示 ，第2實施形態的生理用衛生棉1 A，是在比芯部4 0的背 面42更靠近肌膚抵接面側設有擠壓溝1 1的凹部1 2。像這 樣，在擠壓溝1 1的凹部1 2爲設置在比芯部40的背面42 更靠近肌膚抵接面側的情形下，由於亦在擠壓溝1 1的兩 側形成空間部1 6，因此由穿用者的大腿部朝寬度方向 (WD)施加壓縮力的情形下，突出部1 5能潛入到空間部1 6 。藉此，就能令芯部40突出肌膚抵接面側。 2-2.第3實施形態 採用第9圖至第1 3圖，說明第4實施形態的生理用 衛生棉1C。如第9圖至第1 1圖所示，第4實施形態的生 理用衛生棉1 C ’係分別在表面薄片2、中間薄片5及拭紙 -17- 200913965 7設有朝生理用衛生棉1C的長邊方向（LD)延伸，形成略 縱長的複數個開孔部101、102、103。開孔部1〇1、1〇2、 1 03，係形成狹縫狀，以沿著擠壓溝1 1的方式形成在芯部 40 〇 像這樣，分別在表面薄片2、中間薄片5及拭紙7設 置開孔部1 0 1、1 02、1 03，藉此例如芯部40變形成凸狀的 情形下，由於各開孔部101、102、103是朝寬度方向（WD) 拉伸，可變形成略菱形（參照第1 1圖），因此表面薄片2、 中間薄片5及拭紙7可各自朝寬度方向（WD)拉伸。例如， 產生來自穿用者之大腿部的壓縮力，芯部40變形成凸狀 的情形下，如第1 1圖所示，開孔部1 〇 1、102、103是形 成寬闊開孔，藉此並不會阻礙芯部40的凸狀變形，能使 其變形。再者，爲了不按壓芯部40，使其變形成凸狀，只 要至少配置在比吸收體4更靠近肌膚抵接面側的薄片構件 具有拉伸性即可。 又，由於分別在表面薄片2、中間薄片5及拭紙7設 置開孔部1 0 1、1 02、1 03，藉此就能具有使其往生理用衛 生棉1的寬度方向（W D)的拉伸性或伸縮性，因此例如藉由 自側部4 1傳遞來的力，使芯部4 0變形成凸狀的情形下， 亦不會壓迫吸收體4。藉此，能將表面薄片2等保持低密 度，例如變形成凸狀之後，在加上隨著穿用者之移動的壓 力之情形下，液體等亦難以回流到表面薄片側。亦即’能 減輕因再濕潤的不快感。進而，由於表面薄片2並未壓迫 到吸收體4等，因此凸狀變形時亦能減輕液體等自吸收體 -18- 200913965 4回流。 又’如第12圖所示，生理用衛生棉1C，亦可在表面 薄片2形成凹凸的賦型。藉此，確保表面薄片2的寬度方 向（WD)的拉伸量，表面薄片2就能輕易的朝寬度方向 (WD)拉伸。又，包住吸收體4的拭紙7，也可設置折回部 71。藉由設置折回部71，賦予凸狀變形時所要的延伸份量 。藉此’吸收體4就只有延伸份量的部分能朝寬度方向 (WD)拉伸（參照第13圖）。 又，也可以不在所有的薄片構件使用如上述的拉伸手 段。如果考慮配置在肌膚抵接面側的薄片構件爲延伸的最 長距離的話，至少設置在肌膚抵接面側的表面層側爲宜。 又，不光是加工，亦可使用薄片本身爲線圈狀的捲縮纖維 、聚胺酯等可拉伸的纖維，或使薄片之融合點減少易朝寬 度方向（WD)延伸者。又，可朝長邊方向（LD)加強纖維定向 ，具有使得朝寬度方向（WD)之拉伸強度減少的拉伸性，也 可設置開孔部，具有朝寬度方向（WD)的拉伸性。進而， 加工薄片，即使薄片本身不會延伸，亦可以設置既定之空 間部的方式配置在表面薄片2與吸收體4之間等。藉此， 由於形成有用以使吸收體4等產生變形的變形空間，因與 上述同樣的很容易促進變形。 表面薄片2、中間薄片5及拭紙7，各自以不會阻礙 朝寛度方向之拉伸性的方式，利用螺旋狀的熱熔膠接著劑 接合爲宜。又，例如亦可藉由噴霧法等塗佈，或藉由朝長 邊方向延伸的條紋狀的熱熔膠接著劑等接合。進而，例如 -19- 200913965 亦可將各開孔部1 〇

Description of the Invention [Technical Field] The present invention relates to an absorbent article and a method of manufacturing the same. In particular, it relates to an absorbent article excellent in adhesion and leakproofness and a method for producing the same. [Prior Art] Conventionally, an absorbent article for absorbing excrement such as menstrual blood has been known, for example, a sanitary napkin, a sanitary pad, a diaper, or the like. The absorbent article has an absorbent body that absorbs and retains all menstrual blood, and a liquid-permeable surface sheet disposed on the skin contact surface of the absorbent article, and a non-liquid surface disposed on the garment abutment surface of the absorbent article. The liquid permeable back sheet is worn and worn, for example, in a state of being attached to the underpants. However, in the above absorbent article, in order to surely capture the excrement from the excretory portion of the wearer, it is desirable to use the absorbent portion of the absorbent body in close contact with the excretion portion. For example, if a gap is formed between the wearer's excretion portion and the absorbent article, the excrement of the surface sheet overflowing the absorbent article flows out along the surface sheet, thereby generating excrement to the side of the absorbent article or the hip. Leak, dirty underwear or clothes. In particular, when the sanitary tampon is fixed to the undergarment, if the body is moved in this state, a relative displacement between the underpants and the excrement is likely to occur. This displacement is a cause of the horizontal leakage. Further, for example, since the sanitary napkin is usually held between the wearer's thighs together with the underpants, the wearer's thigh is subjected to a lateral compressive force to cause compression deformation. Thereby, a gap is formed between the wearer's excretion -4-200913965 and the sanitary napkin due to the deformed state of the absorbent body, as described above, which stains the underpants or clothes. In the Japanese Patent Publication No. 09-108262 (hereinafter referred to as Patent Document 1), it is disclosed that the continuous surface sheet and the absorbent body are continuously pressed, thereby forming a pair of pressing grooves, and the respective pressing grooves are respectively The sanitary napkin is disposed in the longitudinal direction of the sanitary napkin to prevent leakage of excrement or the like caused by the distortion of the absorbent body. In the sanitary napkin described in Patent Document 1, for example, a pair of pressing grooves are disposed so as to sandwich a core portion provided at a slightly center portion in the width direction of the sanitary napkin. The squeezing groove is a relatively high-pressure pressing portion and a low-density pressing portion, and is formed in a groove shape on the skin abutting surface side of the sanitary napkin. Thereby, the thigh portion of the wearer is subjected to a lateral compressive force, and even if a distortion is generated in a slightly central portion of the absorbent body, the twist can be prevented from extending to the peripheral portion. As a result, menstrual blood or the like flows out along the twist to prevent leakage from the peripheral portion. In the Japanese Patent Publication No. Hei 10-99372 (hereinafter referred to as Japanese Patent Publication No. 2), it is disclosed that embossing is performed from the skin contact surface side, and is formed to be bent toward the wearer's skin contact surface side. The first flexible shaft and the embossing process from the garment abutting surface side form a second flexible shaft that is curved toward the garment abutting surface side, thereby deforming and absorbing the absorbent body toward the skin abutting surface. Sexual absorbent items. In the absorbent article disclosed in Patent Document 2, the first and second flexible shafts are provided on the skin contact surface side and the garment abutting surface side of the absorbent article, respectively. Therefore, even in the case of -5-200913965 in which the lateral compression force is applied to the thigh portion of the wearer, the absorbent body is easily deformed because it is easily bent on the skin abutting surface side and the garment abutting surface side. The desired shape. [Problems to be Solved by the Invention] However, the sanitary napkin disclosed in Japanese Patent Laid-Open Publication No. Hei. No. 1, the squeezing groove is disposed between a slightly central portion in the thickness direction of the core portion and the back surface of the core portion. Therefore, when the compressive force is applied to the thigh portion of the wearer in the width direction, the force transmitted from the squeeze groove to the core portion spreads from the skin contact surface side in the thickness direction of the absorber to the garment abutment. All directions on the side of the face. Thereby, the core has a tendency to bend in all directions, and there is a problem that a stable deformed shape cannot be obtained frequently. Further, in the absorbent article disclosed in Japanese Patent Laid-Open No. 2, the first flexible shaft is formed closer to the skin contact surface side than the garment abutting surface side of the absorbent body in the thickness direction, and thus the wearer is When the thigh is applied with a compressive force in the direction of the twist, the force transmitted from the first flexible shaft is diffused to the skin contact surface side and the clothing contact surface side in the thickness direction of the absorbent article. direction. In addition, since the groove is formed on the skin contact surface side of the second flexible shaft, even if the force acts on the garment abutting surface side in the garment abutting surface side of the second flexible shaft, it is not possible to obtain the groove. Stable deformation toward the skin side. The present invention has been made in view of the above-described problems, and an object of the invention is to provide an absorbent article which is capable of improving the adhesion to the skin and reducing the leakage of body fluids and the like. -6 - 200913965 In order to achieve the above object, the inventors of the present invention have found that the squeezing groove of the absorbent article is effective in the two predetermined space portions on the surface of the squeezing groove on the side of the garment abutting surface.

Body 4. An adhesive portion 8' is provided on the garment abutting surface side of the back sheet 3 at the adhesive portion 8, and the sanitary napkin 1 is adhered to the wearer's underwear or the like. In the first embodiment, the sanitary napkin 1 includes a liquid-permeable intermediate sheet 5 disposed between the surface sheet 2 and the absorbent body 4, and a side sheet 6 constituting one of the surface layers, and a sanitary napkin. The flanks W1, W2 of the cotton 1 extending in the width direction (WD). Further, the sanitary napkin 1 includes a pressing groove 1 1 in which a concave pressing groove portion is formed toward the back sheet 3 from the skin contact surface side of the surface sheet 2. Health -11 - 200913965 The sanitary napkin 1 divides the absorbent body 4 into a core portion 40 and a side portion 41 by the pressing groove 11. Further, the projecting portion 15 of the back groove portion is formed on the garment abutting surface side of the crush groove 11. On both sides of the protruding portion 15, a space portion 16 is formed which is convex toward the skin contact surface side from the garment abutting surface side. 1-2. The surface sheet 2 such as a surface sheet is placed on the body side of the wearer while being in contact with the excretion portion. The surface sheet 2 may be liquid permeable on the entire surface or partially liquid permeable. Further, it may be constituted by one sheet member or a plurality of sheet members. In the present embodiment, the surface sheet 2 is provided with a liquid permeable region at a substantially central portion in the width direction (WD) of the sanitary napkin 1 and a liquid-impermeable side sheet at the end portion of the width direction (WD). The cover 〇 intermediate sheet 5 is such that the excrement of the permeable surface sheet 2 penetrates into the absorber 4, and also serves as a buffering action at the time of use. The absorbent body 4 is coated on the wipe paper 7 and has a substantially elliptical core portion 40 at a substantially central portion in the width direction (WD) of the sanitary napkin 1. The core portion 40 is a region surrounded by the pressing groove 11. Side portions 41 are formed on both sides of the width direction (WD) of the core portion 40. The core portion 40 and the side portion 41 are divided by the pressing groove 11. In the back sheet 3, a liquid-impermeable sheet member is used, whereby excrement or the like held in the absorbent body 4 is prevented from leaking to the garment abutting surface side of the wearer. 1-3. Squeeze groove and space portion The squeezing groove 1 1 is provided so as to be sandwiched by the core portion 40 so as to extend in the longitudinal direction (LD) of the sanitary napkin 1 toward the physiological -12-200913965. Specifically, as shown in FIGS. 3A and 3B, the pressing groove 11 is provided with a concave portion 12 formed by high pressing and a convex portion 13 formed by low pressing, and the high extrusion by continuous extrusion Pressure and low extrusion are formed. The sanitary tampon 1 is attached to the back side of the squeezing groove 11, and is provided on the garment abutting surface side, and has a rear surface 42 that is closer to the garment abutting surface side than the garment abutting surface side of the core portion 40. Projection 1 5 . On both sides of the protruding portion 15 are provided, a space portion 16 which is convex toward the skin contact surface side from the garment abutting surface side is provided. In the present embodiment, the space portion 16 is formed on both sides of the protruding portion 15 so as to sandwich the protruding portion 15 on the side of the garment abutting surface of the absorbent body 4, and the garment abutting surface is laterally directed toward the skin. The convex side of the junction side is convex. The top of the space portion 16 is formed, for example, so as to be disposed on the skin contact surface side 2 mm higher than the back surface 42 of the core portion 40. In other words, the difference in height in the thickness direction (TD) of the absorbent body 4 formed at the bottom of the pressing groove 1 1 and the top of the space portion 16 is 2 mm. Ideally, the height difference (TD) in the thickness direction (TD) of the concave portion 12 formed at the bottom of the pressing groove 1 1 and the top portion of the space portion 16 is 0. 5 to 10mm range. As long as the height difference (TD) of the absorber 4 at the top of the recess 1 2 and the space portion 16 is 0. In the range of 5 to 10 mm, the protruding portion 15 is more easily formed in the space portion 16 formed on the garment abutting surface side of the core portion 40. Further, in the present embodiment, the space portion 16 is provided on both sides of the protruding portion 15 so as to sandwich the protruding portion 15, but it may be provided only on the side of the core portion 40 as shown in Fig. 4, for example. The space portion 16 is disposed on the side of the core portion 40, and -13-200913965, whereby the protruding portion 15 can be bent at the space portion 16. In other words, it is possible to cause the protruding portion 15 to tilt toward the central portion side in the width direction (WD) of the sanitary napkin 1 through the space portion 16. Thereby, it is possible to ensure a stable deformation form of the protruding portion 15 and a stable deformation form of the core portion 40, and to improve adhesion to the skin. The pressing groove 11 is provided with a pair of wall portions 14 formed by engagement of an embossing device to be described later. When the surface sheet 2 and the absorber 4 are pressed toward the thickness direction (TD) of the sanitary napkin 1, for example, the wall portion 14 generates a strong tensile stress in the center of the thickness direction (TD) of the sanitary napkin 1. The tensile body 4 is stretched by the tensile stress. Further, the wall portion 14 of the absorbent body 4 which has been stretched has a low density at the center. This low-density portion suppresses the diffusion of excrement from the high-density portion when the core portion 40 absorbs the excrement. The pressing groove 11 is formed by, for example, pressing the surface sheet 2 and the absorbent body 4 which are continuous from the skin contact surface side and the garment abutting surface side, respectively, but the present invention is not limited thereto. For example, as shown in Fig. 5, the squeezing groove 1 1 may be formed by continuously squeezing the absorbent body 4 from the skin abutting surface side and the garment abutting surface side, respectively. In the case where the absorbing body 4 forms the squeezing groove 1 1 , since the surface sheet 2 does not press the absorbing body 4 by pressing, the absorbing body 4 is easily deformed. Further, the pressing groove 1 1 can be formed by continuously pressing the intermediate sheet 5 and the absorbent body 4 from the skin contact surface side and the garment abutting surface side, respectively. For example, in the case where the intermediate sheet 5 formed of synthetic resin fibers or the like and the absorbent body 4 are continuously pressed from the skin contact surface side and the garment abutting surface side, the pressing groove is formed so as to easily maintain the protruding clothing. The shape of the junction side. -14- 200913965 The pressing groove 11 can also be provided with an opening 17 in the recess 12. By providing the opening 17, the excrement transferred from the surface sheet 2 can be dropped to the lower layer of the core 40. The back sheet 3' on the side of the garment abutting surface allows the excrement to fall to the back sheet 3, thereby suppressing the diffusion of excrement to the surface layer containing the surface sheet 2. Further, an opening 18 may be provided in the side wall portion 14. Also in this case, the excrement "conveyed from the surface sheet 2 can be dropped to the back sheet 3 provided on the garment abutting surface side of the layer below the core portion 40. Further, it is preferable that the opening 18 is pressed so that the side wall portion does not break. Further, in the present embodiment, the adhesive portion 8' is provided at all positions corresponding to the protruding portion 15 of the back surface of the pressing groove 11, but the present invention is not limited thereto. The adhesive portion 8 may be provided at least at a position corresponding to a portion of the protruding portion 15. In the present embodiment, the adhesive sheet 8 for preventing the offset is disposed on the garment abutting surface side of the crushing groove 1 1 in the back sheet 3, thereby forming a skin contact surface that does not interfere with the core portion 40. The side changes are convex, but the invention is not limited thereto. For example, the adhesive portion 8 may be provided on the garment abutting surface side of the back sheet 3 in a state including the center of the longitudinal direction (LD) of the sanitary napkin 1. By this, the highlights! 5, the core 40 can be placed together with the undergarment 70 joined to the core 4 by the hot melt adhesive 8a joining the absorber 4 and the back sheet 3 more often than the core 40 is disposed on the abutting side of the garment. — The deformation is convex. Further, the hot melt adhesive 8a of the absorbent body 4 and the back sheet 3 may leave the back surface 42 of the back sheet 3 joined to the core portion 4''. Specifically, at least -15-200913965 may be combined with the back surface of the squeezing groove 11 and the back sheet 3. By this, the back sheet 3 and the back surface 42 of the core 40 can be separated from each other by the application of the compressive force in the width direction (WD) by the wearer's thigh portion, forming a predetermined space 28' by sneaking into the protrusion 15 To the space 2, the core 40 can be stably deformed. In this manner, the sanitary napkin 1 can be formed into a stable convex shape on the skin contact surface side by providing the pressing groove 1 1 and the space portion 1 6 ' core portion 40. For example, when a compressive force is applied from the wearer's thigh, a compressive force is applied in the direction of the arrow shown in Fig. 6A. At this time, the compressive force is transmitted to the core 40 through the squeezing groove 1 1 '. Here, the protruding portion 15 as shown in Fig. 6B is disposed on both sides of the space portion 16 and thus is deformed and moved toward the back surface 42 side of the core portion 40. Specifically, the protruding portion 15 moves so as to sneak into the space portion 16 formed between the protruding portion 15 and the back surface 42 of the adjacent core portion 40. The protruding portion 15 that moves in a submerged manner further transmits a compressive force so that the back surface 42 of the core portion 40 is pressed against the core portion 40. Thereby, the core portion 40 is formed to protrude from the abutting surface side of the skin, and is adhered to the excretory portion of the wearer. Further, as shown in Figs. 7A and 7B, the sanitary napkin 1 is fixed to the garment abutting surface side of the pressing groove 1 1 , that is, the protruding portion 15 , and is fixed to the underpants 70, for example, by squeezing The groove 1 1 can be positioned closer to the garment abutting surface side than the core portion 40, so that the core portion 40 can be deformed into a stable convex shape. Further, the sanitary napkin 1' is folded into the garment abutting surface side of the underpants 7 , so that the side flaps W1, W2 are then 'by, for example, applied from the wearer's thigh portion in the width direction (WD) In the case of the compressive force, since the movement in the thickness direction (TD) toward the side portion 4 1 is restricted, the projection portion 15 becomes very large - 1613, and it is easy to sneak into the space portion 1 6 to be stably deformed. 2 . Other Embodiments The other embodiments will be described with reference to Figs. 8 to 13'. In the above embodiment, the portion which is not particularly described is the same as that of the first embodiment, and the same reference numerals are attached to the same reference numerals as in the first embodiment. 2-1. (Second Embodiment) The sanitary napkin 1A of the second embodiment will be described with reference to Fig. 8. In Fig. 8, in order to facilitate the understanding of the features of the present invention, the drawings are only partially enlarged views showing the squeezing grooves of the sanitary napkin 1A. As shown in Fig. 8, the sanitary napkin 1A of the second embodiment is a recessed portion 1 2 in which the pressing groove 1 1 is provided closer to the skin contact surface than the back surface 42 of the core portion 40. In this manner, in the case where the concave portion 1 2 of the pressing groove 1 1 is provided closer to the skin contact surface side than the back surface 42 of the core portion 40, the space portion 16 is also formed on both sides of the pressing groove 1 1 . Therefore, in a case where a compressive force is applied to the widthwise direction (WD) of the wearer's thigh portion, the protruding portion 15 can sneak into the space portion 16 . Thereby, the core 40 can be made to protrude from the skin abutting side. 2-2. (Third Embodiment) The sanitary napkin 1C of the fourth embodiment will be described with reference to Figs. 9 to 13 . As shown in Fig. 9 to Fig. 1, the sanitary napkin 1 C ' of the fourth embodiment is provided with a sanitary napkin 1C for the surface sheet 2, the intermediate sheet 5, and the wipe sheet -17-200913965, respectively. The longitudinal direction (LD) extends to form a plurality of openings 101, 102, and 103 that are slightly longer. The opening portions 1〇1, 1〇2, and 203 are formed in a slit shape so as to be formed on the core portion 40 along the pressing groove 1 1 so as to be in the surface sheet 2, the intermediate sheet 5, and the wiper, respectively. The paper 7 is provided with the opening portions 1 0 1 , 102 , and 103 , whereby, for example, when the core portion 40 is deformed into a convex shape, since the respective opening portions 101, 102, and 103 are stretched in the width direction (WD), The shape may be slightly diamond-shaped (refer to FIG. 1), and thus the surface sheet 2, the intermediate sheet 5, and the wipe sheet 7 may each be stretched in the width direction (WD). For example, when a compressive force is generated from the thigh of the wearer and the core 40 is deformed into a convex shape, as shown in FIG. 1, the opening portions 1 〇 1, 102, and 103 are formed into wide openings. Thereby, the convex deformation of the core portion 40 is not hindered, and it can be deformed. Further, in order to prevent the core portion 40 from being pressed, the sheet member is formed into a convex shape, and at least the sheet member disposed closer to the skin contact surface side than the absorbent body 4 may have stretchability. Further, since the opening portions 10, 01, and 103 are provided in the surface sheet 2, the intermediate sheet 5, and the wiper 7, respectively, the width direction (WD) of the sanitary napkin 1 can be made. Since the stretchability or the stretchability is made, for example, when the core portion 40 is deformed into a convex shape by the force transmitted from the side portion 41, the absorber 4 is not pressed. Thereby, the surface sheet 2 or the like can be kept at a low density, for example, after being deformed into a convex shape, it is difficult to return the liquid or the like to the surface sheet side with the pressure of the movement of the wearer. That is, it can reduce the unpleasant feeling of rewetting. Further, since the surface sheet 2 is not pressed against the absorber 4 or the like, it is possible to reduce the backflow of the self-absorbent body such as a liquid during the convex deformation. Further, as shown in Fig. 12, the sanitary napkin 1C can also form irregularities on the surface sheet 2. Thereby, the amount of stretching of the width direction (WD) of the surface sheet 2 is ensured, and the surface sheet 2 can be easily stretched in the width direction (WD). Further, the folded portion 71 may be provided to wrap the wiper 7 of the absorbent body 4. By providing the folded portion 71, the amount of extension required for the convex deformation is given. Thereby, only the portion of the absorbent body 4 which is stretched can be stretched in the width direction (WD) (refer to Fig. 13). Further, the stretching means as described above may not be used for all of the sheet members. When it is considered that the sheet member disposed on the skin contact surface side is the longest distance to extend, it is preferable to provide at least the surface layer side on the skin contact surface side. Further, not only the processing, but also a stretchable fiber such as a coiled fiber or a polyurethane such as a melamine, or a fused point of the sheet may be used to easily extend in the width direction (WD). Further, the fiber orientation can be reinforced in the longitudinal direction (LD), and the stretchability in the tensile direction in the width direction (WD) can be reduced, and the opening portion can be provided, and the stretchability in the width direction (WD) can be provided. . Further, the sheet is processed, and even if the sheet itself does not extend, it can be disposed between the surface sheet 2 and the absorber 4 so as to be provided with a predetermined space. As a result, a deformation space which is useful for deforming the absorber 4 or the like is formed, and deformation is easily promoted in the same manner as described above. The surface sheet 2, the intermediate sheet 5, and the wipe sheet 7 are preferably joined by a spiral hot melt adhesive, so as not to impede the stretchability in the twist direction. Further, for example, it may be applied by a spray method or the like, or may be joined by a stripe-shaped hot melt adhesive or the like extending in the longitudinal direction. Further, for example, -19-200913965 may also perform embossing between each of the opening portions 1 〇 1 by using a predetermined embossing 1 14 , whereby the respective bonding surface sheets 2, the intermediate sheets 5 and the wipes are used. Paper 7. At this time, the shape of the embossing 1 14 may be, for example, a polygonal shape, an elliptical shape, a vertically long shape, a star shape or the like in addition to the slightly circular shape shown in Fig. 9. Further, if the joining in the twist direction is considered, and the stretchability is hindered, it is preferable to use discontinuous joining. 3 .

Further, as shown in Fig. 19, in the second embodiment of the present invention, for example, the convex portion pitch A of the upper embossing roller 1 〇1 can be used as 37 mm, the upper embossing roller 1 〇1 and the lower embossing. The spacing of the meshing portions of the roller 1 〇 2 is 0. 75mm, the depth of engagement C below the protruding groove 11 is 3. 0mm, the side wall portion angle D of the pressing groove 1 1 facing the lower embossing roller 1 〇 2 is 80, and the embossing distance from the bottom surface of the upper embossing roller 〇1〇1 to the bottom surface of the lower embossing roller 102 is 12 mm. Rollers 101, 102. The convex portion pitch A of the upper embossing roller 1 〇1 is preferably in the range of 20 to 60 mm in order to deform the core portion 40 into a convex shape, and the range of 3 〇 to 5 〇 mm is preferably such that the convex portion pitch A is Below 25 mm, for example, the distance from the center of the pressing groove n to the center of the core portion 4 is too short, and it takes a large force to form a convex shape, and deformation is not easy. Further, if the pitch A of the convex portion is 50 m or more, for example, the distance of the pressure groove j is too long, and in the deformation, the bending is caused in the crush groove 11. The interval b ′ of the meshing portion of the upper pressure roller 1 与 1 and the lower pressure roller 1 0 2 is 0. A range of 3 to 10 mm is suitable. Better yet. 5~5. The range of 〇mm is appropriate. When the interval B of the engaging portion is 〇 · 3 m m or less, for example, when the basis weight of the absorbent body 4 - 25 - 200913965 is increased, it becomes difficult to mesh. Further, when the interval B of the engaging portion is 10 mm or more, for example, when the basis weight of the absorbent body 4 is low, it is impossible to form a mold for causing the pressing groove to protrude. The depth of engagement for the pressing groove to protrude downward is preferably in the range of 1 to 10 mm. More preferably, the range of 2 to 6 mm is suitable. If the meshing depth C is 1 mm or less, for example, the meshing concave portion 1 1 2 cannot be sufficiently formed, and the deformation is not smooth. Further, if the meshing depth C is 10 mm, for example, the suction body 4 of the meshing portion cannot be stretched, the absorber 4 is broken, and the crush groove 11 and the core portion 40 are separated from each other. The angle D of the side wall portion of the pressing groove 11 facing the lower embossing roller 102 is preferably in the range of 30 to 12 〇. More preferably, the range of 45 to 100 ° is suitable. When the side wall portion angle D is 30 or less, for example, no protrusion is formed on the garment abutting surface side of the pressing groove n. In addition, when the angle D of the side wall portion is 1 to 20 or less, for example, it is difficult to separate the metal plate (or the metal roller) which is engaged with the engagement groove 1 1 at the biting portion after the biting, and the continuous production is hindered. The distance E from the bottom surface of the upper embossing roller 101 to the bottom surface of the lower embossing roller is preferably 5 to 30 mm. More preferably, the range of 8 to 15 mm is suitable. Further, although in the present embodiment, it is a case where the lower embossing roller 102 formed by the corresponding embossing roller 101 is added to the concave portion, or the upper embossing roller 1 〇1 is engaged to engage the lower embossing roller 1 0 2 The manner of forming is convex, but the invention is not limited thereto. The lower embossing roller 012 is formed into a flat surface having no irregularities. When the upper embossing roller 101 is engaged with the upper embossing roller 101, the same configuration can be realized by the manufacturing device which is a concave portion. For example, materials such as paper or hard rubber which are highly variable in compression can also be used. -26- 200913965 Further, the engagement concave portion 112 and the embossing wheels 110 and 1 1 1 for forming the pressing groove 11 are also different depending on the place where the pressing groove 1 1 is formed. For example, Fig. 20 shows the arrangement of the engaging recess 112 and the embossing wheels 110, 111. As shown in Fig. 20, the shape in which the engagement recess 11 2 and the embossing wheels 1 1 〇 and 11 11 are used differs depending on the A portion, the B portion, and the C portion. For the A portion, for example, the engagement recess 1 1 2 and the embossing wheel 110' 111 of the shape shown in Fig. 21 are preferable. Further, in the case of the B portion, the difference from the A portion is the most likely to be subjected to the pressure from the thigh portion and is located in the vicinity of the excretion portion. Therefore, it is necessary to accurately protrude the garment abutting surface side. Therefore, the engagement is stronger than the peripheral area, and it is necessary to increase the distance to extend, for example, the meshing concave portion 112 and the embossing wheels 110, 111 shown in Fig. 2B. Further, with respect to the C portion, since the protruding portion extending in the width direction (WD) is formed, the absorbent body 4 is liable to block the slightly splayed portion of the engaging portion of the embossing roller 102. Therefore, it is necessary to have the side of the embossing wheel 1 1 0, 1 1 1 engaged with the engaging recess 1 1 2 inclined, for example, the shape shown in the 2 1 C figure, after the engagement, with the absorbent body 4 being easily pulled out. Preferably, the engaging recess 1 1 2 is suitable. Further, since it is an embossing extending in the width direction (WD), as shown in Fig. 21C, the corner of the embossing wheel 111 is inclined to reduce the breakage of the sheet.
