201103507 體的內部側或外部側的至少其中一方。 作爲其他理想實施形態之一，前述空間是藉 述開口部的周緣與前述支承體之間的間隔件所區 ，藉由前述間隔件的周壁、前述支承體、以及前 的周緣，來限制前述閥體的縱方向及橫方向的移 作爲其他理想實施形態之一，前述支承體包 液性之纖維不織布。 第2發明是關於包含主體，該主體具有縱方 向；身體側及其相反側；及相連於前述縱方向之 域、後腰圍區域及位於前述前後腰圍區域間的胯 穿著用物品的改良。 此第2發明是至少包含位於前述胯部區域之 處理用品，前述體液處理用品的開口部是朝前述 □。 作爲第2發明理想實施形態之一，前述主體 成於前述胯部區域之主體開□，該主體開口位於 處理用品的開口部，而前述收容體位於前述主體 反側。 作爲其他理想實施形態之一，至少在前述胯 包含可吸收體液的吸液構造體，前述吸液構造體 體側及其相反側、和將其朝厚度方向貫通之吸液 吸液開口位於前述體液處理用品的開口部，而前 位於前述吸液構造體的前述相反側。 由位於前 劃而成的 述開口部 勖。 含具有透 向及橫方 前腰圍區 部區域之 前述體液 身體側開 是包含形 前述體液 的前述相 部區域， 是包含身 開口，該 述收容體 201103507 [發明效果] 在第1發明的體液處理用品，因在收容體的開口部， 形成有可供體液自收容體外部朝內部流入，並且可防止體 液自收容體內部朝外部逆流之逆流防止手段，所以，可抑 制體液自體液處理用品漏出。作爲體液處理用品，包含可 與開口部水密地接觸之閥體，當閥體與開口部的周緣接觸 時，可抑制體液自收容體內部漏出。 針對第2發明的穿著用物品，因使體液處理用品至少 位於胯部區域，而收容體的開口部朝身體側開口，所以， 在例如使用紙尿布等的穿著用物品之情況，能以體液處理 用品保持已排泄的尿液。因此，能夠抑制尿液等自穿著用 物品漏出。 【實施方式】 [實施例1] 圖1〜4是顯示本發明的體液處理用品的一例，圖1爲 體液處理用品1的平面圖，圖2爲圖1的II-II線斷面槪要圖 ，圖3是體液處理用品1的部分斜視圖，圖4是體液處理用 品1的說明圖。在圖1及3，爲了說明，將其一部分予以剖 面顯示。如圖所示，體液處理用品1是具有縱方向γ及橫方 向X，包含具有複數個開口部11之不透液性的收容體10; 和形成於與開口部1 1相對應的位置之逆流防止手段20。 收容體10是包含位於身體側之第1薄片12、與位於身 體側相反側之穿衣側的第2薄片1 3，在其周圍將這些第1及 -8- 201103507 第2薄片12’ 13接合’形成爲袋狀。在第1薄片12，形成有 朝厚度方向貫通之開口部1 1，作爲體液之尿液從該開口部 11流入。鄰接的開口部11是配置成在縱方向γ及橫方向X 上不會相互重疊。作爲第1及第2薄片12，13，能夠採用不 透液性的薄片’例如，塑膠薄膜與纖維不織布之層積體、 具有極細纖維的較高密度之熔噴纖維不織布等的纖維不織 布。 逆流防止手段2 0是包含：與開口部1 1相對應，並且位 於第1薄片1 2的收容體1 〇內部側，比重較尿液等的體液小 的平板狀的閥體30;防止閥體30脫落至收容體1〇內部之薄 片狀的支承體40;和介裝於第1薄片12與支承體40之間的 間隔件5 0。 閥體30是例如能夠使用由較收容體1〇、支承體40等更 高剛性、且具有耐水性之纖維薄片體、發泡塑膠、紙質材 料所構成之不透液性薄片，具有：位於第1薄片1 2側之閥 體上面31;位於第2薄片13側之閥體下面32。閥體30是與 複數個開口部11相對應而形成有複數個，並且其面積較開 口部11的開口面積更廣，閥體上面31的周緣部可與開口部 1 1的收容體1 〇內部側的開口部周緣1 4水密地接觸。在此實 施形態，開口部1 1的直徑作成爲大約6mm，閥體30的直徑 作成爲大約12.5mm。但是，不限於此尺寸’可因應開口部 1 1的數量、位置、體液處理用品1的大小等等作適宜地變 更。 在第1薄片12與支承體40之間，配置有間隔件5〇。作 201103507 爲間隔件5 0 ’可使用例如纖維薄片體、發泡塑膠、紙質材 料等保形性較高者。間隔件50是大致呈橢圓形，具有覆蓋 所有複數形成的開口部11之面積，使長徑方向縱方向γ — 致’而使短徑方向與橫方向X—致。間隔件50包含位於第1 薄片1 2側之間隔件上面5丨、和位於第2薄片丨3側之間隔件 下面52，間隔件上面5 1抵接於第1薄片1 2，間隔件下面52 抵接於支承體40，分別藉由接著劑等的接合手段接合著。 在間隔件5 0，與開口部1 1對應形成有從間隔件上面5丨朝間 隔件下面52貫通的間隔件開口 53，在間隔件開口 53，分別 配置有閥體3 0。作爲支承體40，可使用例如透液性的纖維 不織布。 在第1薄片1 2與支承體4 0之間，藉由間隔件開口 5 3形 成有空間15。閥體30是在此空間15，可朝間隔件50的厚度 方向移動地被支承著。即，間隔件開口 5 3的直徑是較開口 部1 1的直徑更大，且較閥體3 0的直徑更大。間隔件5 0的厚 度尺寸是較閥體30更大。具體而言，閥體30的厚度大約爲 0.5mm，間隔件50的厚度尺寸大約爲2mm。 因在間隔件下面52接合有支承體40，所以不會有閥體 30脫落至收容體10內部的情況。又，閥體30藉由間隔件50 的周壁、開口部周緣1 4、和支承體40，限制其縱方向Y及 橫方向X的移動。 當尿液等的體液排泄到這樣的體液處理用品1的開口 部1 1時，因體液的重量使得閥體30朝支承體40側被壓下， 閥體下面32與支承體40接觸而被支承。開口部周緣14與閥 -10 - 201103507 體上面31分離，體液通過閥體30的周圍而流入到空間15。 且體液通過支承體40而流入到收容體〗0的內部。因收容體 10爲不透液性且呈袋狀，所以體液在收容體10內被保持》 從體液被保持於收容體10內之狀態，如圖4所示，在 收容體1 〇上下顛倒的情況，體液會朝開口部1 1移動，閥體 30的閥體下面32被透過支承體40的體液所按壓，朝第1薄 片12側移動。閥體30之閥體上面31與開口部周緣14接觸。 由於閥體30被體液所按壓，故可在與開口部周緣14之間水 密地接觸，可防止體液朝收容體10外部流出。 又，因閥體3 0之比重較體液小，所以可浮在體液中。 在收容體10爲圖2所示的狀態下，尿液等的體被保持於收 容體10內之情況，因閥體30浮在體液中，所以在體液要從 開口部1 1流出之前，開口部1 1會被閥體3 0關閉。因此，即 使在此情況，亦可防止體液朝收容體10外部流出。 當在閥體30與第1薄片12之間殘存有稍許體液這樣的 情況，藉由體液的表面張力，可使閥體上面31與第1薄片 1 2的開口部周緣1 4更水密地接觸，能使防止收容體1 0內部 的體液流出之效果提升。 因藉由形成複數個開口部11及逆流防止手段20，所以 因某些理由造成任一閥體30無法朝厚度方向移動，也能迴 避逆流防止手段20的領區域之全面性功能不全的情況產生 。又，亦可因應需要將複數個開口部11及逆流防止手段20 形成於廣範圍，可確實地將體液收容於收容體10內部。 圖5〜7是顯示包含前述這樣的體液處理用品1之穿著 -11 - 201103507 用物品的一例者。作爲穿著用物品’以用後即棄式紙尿布 2作爲其一例進行說明。 圖5爲紙尿布2的斜視圖，圖6爲解除圖5的兩側緣的接 合時之紙尿布2的平面圖’圖7爲圖6的VII-VII線斷面圖。 在圖5及6中，爲了說明而將其一部分剖斷，顯示讓各彈性 構件抗衡其收縮力而伸長，將紙尿布2保持成平面狀之狀 態。紙尿布2包含主體60、和吸液構造體70。主體60包含 相連於縱方向Y之前腰.圍區域61、後腰圍區域62、以及位 於前後腰圍區域61，62間的胯部區域63，並且具有將橫方 向X的尺寸分成兩分之縱假想中心線P-P、和縱方向Y的尺 寸分成兩分之橫假想中心線Q-Q。 主體60是包含有形成於身體側之襯墊64、位於其相反 側之穿衣側的外面65、朝縱方向Y延伸的主體兩側緣66、 以及朝橫方向X延伸的主體前後端線67，68。主體兩側緣 66是在胯部區域63朝假想中心線P-P彎曲。襯墊64及外面 65可採用液透過性的纖維不織布等在本發明所屬之技術領 域中的慣用材料。 沿著主體兩側緣66，至少在胯部區域63，腳彈性體82 在伸長狀態下可收縮地被安裝著。腳彈性體82是在襯墊64 與外面65之間，至少接合於其中一方。 沿著主體前後端緣67，68，寬度較廣的腰圍彈性體81 在伸長狀態下可朝橫方向X收縮地被安裝著。腰圍彈性體 8 1是接合於襯墊64之更靠近身體側。作爲腰圍彈性體8 1及 腳彈性體82，可使用伸縮性的纖維不織布。但是’不限於 -12- 201103507 伸縮性纖維不織布，能夠使用這種物品之習知的彈性體。 如圖5所示’主體兩側緣66是在前後腰圍區域61，62相互 地接合，形成短褲型的紙尿布2。 在主體60，形成有至少在胯部區域63，將襯墊64及外 面65朝厚度方向貫通的主體開口 69。在此實施形態，主體 開口 69是形成爲從胯部區域63朝前後腰圍區域61，62延伸 之略橢圓形。在這些襯墊64與外面65之間，以封住主體開 口 69的方式，配置有頂薄片17。在頂薄片17，比起橫假想 中心線Q-Q更靠近主體前端緣67側之位置，形成有略圓形 的頂開口 1 8。頂開口 1 8是將頂薄片1 7朝其厚度方向貫通， 具有較主體開口 69的開口面積更小的面積。 在外面65的穿衣側，以封住主體開口 69的方式即與頂 薄片17重疊的方式，形成有吸液構造體70。吸液構造體70 包含有身體側及其相反側之穿衣側、吸液性芯材7 1、和覆 蓋此吸液性芯材7 1之被覆薄片72，在比起橫假想中心線Q-Q更靠近主體前端緣67側的位置，以與頂開口 18重疊的方 式形成有吸液開口 74。吸液開口 74是將吸液性芯材7 1朝其 厚度方向貫通。吸液性芯材7 1是絨毛漿與高吸收性聚合物 粒子之混合物等這種該發明所屬之技術領域中的慣用材料 ，而被覆薄片72是液擴散性的薄紙等這種該發明所屬之技 術領域中的慣用材料。 在吸液構造體7〇的穿衣側，安裝有體液處理用品1， 且在該穿衣側尙安裝有覆蓋薄片73。覆蓋薄片73能夠使用 不透液性的薄膜等。又，在覆蓋薄片73的更靠近穿衣側的 -13- 201103507 位置，亦可配置纖維不織布來提升肌膚觸感。 配置於吸液構造體70與覆蓋薄片73之間的體液處理用 品1，其第1薄片12位於吸液構造體70側，而第2薄片13位 於覆蓋薄片73側。體液處理用品1的開口部1 1是配置於比 起橫假想中心線Q-Q更靠近主體前端緣67側的位置，經由 吸液構造體70的吸液開口 74及頂開口 18，朝身體側露出。 開口部1 1是位於可與穿用者的外性器對應的位置。 在前述這樣的紙尿布2，在有穿用者排尿液之情況， 尿液會從開口部1 1被收容到體液處理用品1的收容體1 0。 當體液處理用品1處於圖2的狀態時，尿液會通過閥體30的 周圍而被收容體10收容，而當穿用者橫躺或趴下而成爲圖 4的狀態時，閥體30與第1薄片12的開口部周緣14水密地接 觸，可防止已被收容體1 0所收容的尿液朝穿用者側逆流。 又，在穿用者坐下使體壓作用於體液處理用品1的情況， 被收容於收容體10之尿液的水位在收容體10內會上升，但 是因閥體30之比重較尿液等的體液更小，所以可浮在尿液 中，其結果，在尿液自收容體10流出之前，閥體30的閥體 上面21會與第1薄片12的開口部周緣14接觸。因此，在此 情況亦可防止尿液朝身體側逆流。因可防止尿液自體液處 理用品1的逆流，所以能夠抑制尿液從紙尿布2漏出。 就算尿液從體液處理用品1的開口部1 1偏移排泄，或 自收容體10滴下，在開口部11的周圍存在有吸液構造體7〇 ，所以能夠藉由吸液構造體70來吸收漏出的尿液。因此， 能夠更進一步抑制尿液從紙尿布1漏出。又，雖然保持閥 -14- 201103507 體3 0之空間1 5是藉由間隔件5 0來形成的，但是藉由將閥體 作成爲薄片狀，能夠縮小間隔件5 0的厚度方向的尺寸，可 減少對穿用者之不舒適感。 在此實施形態’作成爲於紙尿布2的吸液構造體70形 成有吸液開口 74’讓體液處理用品1的開口部丨丨露出於吸 液開口 74的結構’但是亦可使體液處理用品1全體位於吸 液構造體7〇的身體側。在此情況，能夠在主體60與吸液構 造體70之間形成體液處理用品1。 在主體60形成有主體開口 69，但是並非一定需要形成 主體開口 69。在此情況，藉由至少將體液處理用品1的開 口部1 1所位在的部分作成爲液透過性，能夠使尿液等的體 液透過位於主體60的穿衣側之體液處理用品1。又，亦可 在主體60的身體側形成體液處理用品1。不論何種情況， 只要可經由體液處理用品1的開口部1 1讓尿液等的體液收 容至收容體10即可。作爲收容體10採用不透液性者，但是 不限於不透液性者。若爲可收容經由開口部1 1所流入的體 液者，則亦可爲透液性者，或亦包含例如以吸液性芯材保 持體液這種的情況。但是，在使用透液性薄片作爲第1薄 片12之情況，爲了可達到開口部周緣14與閥體30之水密接 觸，至少需要開口部周緣1 4爲不透液性。例如，在使用透 液性纖維不織布作爲第1薄片12之情況，可藉由在開口部 周緣1 4黏貼不透液性的薄膜來實現，又，在將對疏水性纖 維不織布實施親水處理者作爲第1薄片12來使用之情況， 亦可藉由僅在開口部周緣14不實施親水處理來實現。 -15- 201103507 [實施例2] 圖8及圖9是顯示本發明的實施例2的圖，圖8爲體液處 理用品1的部分平面圖，爲了說明而將其一部分剖斷，圖9 爲圖8的IX-IX線斷面圖。在此實施例2，體液處理用品1並 非將開口部1 1直接形成於第1薄片1 2，而是另外具備形成 有開口部1 1之保形構件90爲其特徵。關於此特徴以外的其 他構成要素，是與實施例1相同，針對相同的構成要素省 略其詳細說明。 在形成有收容部10之第1薄片12，形成有用來安裝保 形構件90之安裝開口 16。在安裝開口 16的第2薄片13側， 形成有開口部Π之保形構件90是經由接著劑等的接合手段 接合著。保形構件90能夠使用例如，纖維薄片體、發泡塑 膠、紙質材料等保形性較高者，具有較第1薄片12更高的 剛性。保形構件90包含有位於第1薄片12側之保形上面91 、和位於第2薄片13側之保形下面92，保形上面91接合於 第1薄片12的安裝開口 16的周緣，而保形下面92接合於間 隔件50的間隔件上面51。 藉由在保形構件90形成開口部11，將其形成於第1薄 片1 2，比起直接在第1薄片1 2形成開口部1 1之情況，能夠 保持開口部1 1的形狀。在開口部1 1歪曲造成其形狀崩潰之 情況，閥體30變得不易密接於開口部周緣1 4，會有在這些 之間產生間隙之可能性。當產生間隙時，會有尿液等的體 液從該處漏出之可能性，但是藉由保持開口部1 1的形狀， -16- 201103507 可使閥體3 0更確實水密地接觸，能夠防止體液漏出。在此 實施例’開口部周緣14是藉由保形構件90的保形下面91來 形成的。 因在保形構件90形成開口部11，將其接合於第I薄片 1 2即可，所以比起在第1薄片1 2直接形成開口部1 1之情況 ，能更容易進行形成作業。即，因保形構件9 0具有較第1 薄片1 2更窄的面積、且剛性高，所以容易進行處理，且亦 容易形成開口部1 1。又，雖然將保形構件90與間隔件50作 成爲不同構件，但是亦能以相同構件來形成這兩個構件。 保形構件90是安裝於第1薄片12的第2薄片13側，即， 收容體1 〇內部側，但是亦可安裝於其相反側之收容體1 0外 部側。這樣的體液處理用品1能夠如實施例1 一樣地使用於 紙尿布2這樣的穿著用物品。 [實施例3] 圖10及11是顯示本發明的實施例3者，圖10是將體液 處理用品1的平面圖的一部分剖斷者，圖1 1爲圖10的ΧΙ-ΧΙ 線斷面圖。在此實施例3，於第1薄片1 2形成有1個開口部 11爲其特徵，其他的構成要素是與實施例1相同。針對相 同構成要素，省略其詳細說明。 在第1薄片12，形成有1個開口部11。在第1薄片12與 第2薄片13之間，可與開口部周緣14接合分離地形成有閥 體30。 因將開口部1 1作成一部位，所以容易形成該開口部， -17- 201103507 且安裝於開口部1 1之閥體30也爲一個即可，所以能夠削減 零件數量。在此實施例3 ’亦可如實施例2同樣地在保形構 件形成開口部11 ’而將保形構件安裝於第1薄片12。又， 這樣的體液處理用品1能夠使用於如實施例1這樣的紙尿布 2。 【圖面簡單說明】 圖1是實施例1的體液處理用品的平面槪要圖。 圖2是圖1的II-II線斷面槪要圖》 圖3是體液處理用品的說明圖。 圖4是體液處理用品的說明圖。 圖5是紙尿布的斜視圖。 圖6是紙尿布的展開平面圖。 圖7是圖6的VII-VII線斷面圖。 圖8是實施例2的體液處理用品的部分槪要圖》 圖9是圖8的IX-IX線斷面槪要圖。 圖〗〇是實施例3的體液處理用品的部分槪要圖。 圖1 1是圖10的XI-XI線斷面槪要圖。 【主要元件符號說明】 1 :體液處理用品 2 :紙尿布（穿著用物品） 1 0 :收容體 1 1 :開口部 -18- 201103507 1 4 :開口部周緣 1 5 :空間 20 :逆流防止手段 3 〇 :閥體 40 :支承體 5 〇 :間隔件 60 :主體 61 :前腰圍區域 62 :後腰圍區域 6 3 :胯部區域 6 9 :主體開口 70 :吸液構造體 7 4 :吸液開口 90 :保形構件 -19BACKGROUND OF THE INVENTION 1.

Therefore, for example, when a wearing article such as a disposable diaper is used, it can be treated with body fluid. Supplies keep the excreted urine. Therefore, leakage of urine or the like from the wearing article can be suppressed. [Embodiment] [Embodiment 1] Figs. 1 to 4 are views showing an example of a body fluid treatment article of the present invention, Fig. 1 is a plan view of a body fluid treatment article 1, and Fig. 2 is a schematic sectional view taken along line II-II of Fig. 1. 3 is a partial perspective view of the body fluid treatment article 1, and FIG. 4 is an explanatory view of the body fluid treatment article 1. In Figs. 1 and 3, a part of the same is shown for the sake of explanation. As shown in the figure, the body fluid treatment article 1 is a container body 10 having a liquid crystallinity having a plurality of openings 11 in the longitudinal direction γ and the lateral direction X, and a counterflow formed at a position corresponding to the opening portion 1 1 Prevention means 20. The container 10 includes a first sheet 12 on the body side and a second sheet 13 on the side opposite to the body side, and the first and -8-201103507 second sheets 12' 13 are joined around the body. 'Formed in a bag shape. In the first sheet 12, an opening portion 1 which penetrates in the thickness direction is formed, and urine which is a body fluid flows in from the opening portion 11. The adjacent opening portions 11 are arranged so as not to overlap each other in the longitudinal direction γ and the lateral direction X. As the first and second sheets 12, 13, a liquid-impermeable sheet, for example, a laminate of a plastic film and a fiber nonwoven fabric, or a fiber nonwoven fabric of a high-density melt-blown fiber nonwoven fabric having extremely fine fibers can be used. The backflow prevention means 20 includes a flat valve body 30 which is located on the inner side of the housing 1 of the first sheet 12 and which is smaller than the body fluid such as urine, and the valve body 30 30, a sheet-like support body 40 that has fallen into the inside of the housing 1; and a spacer 50 interposed between the first sheet 12 and the support 40. The valve body 30 is, for example, a liquid-impermeable sheet made of a fiber sheet, a foamed plastic or a paper material which is more rigid and has water resistance, such as a container 1 or a support 40, and has a liquid-impermeable sheet. 1 a valve body upper surface 31 on the side of the sheet 1 2; and a valve body lower surface 32 on the side of the second sheet 13 side. The valve body 30 is formed in plural numbers corresponding to the plurality of openings 11 and has a larger opening area than the opening portion 11, and the peripheral portion of the valve body upper surface 31 and the housing 1 of the opening portion 1 are inside. The peripheral edge of the opening portion 14 is in watertight contact. In this embodiment, the diameter of the opening portion 1 1 is approximately 6 mm, and the diameter of the valve body 30 is approximately 12.5 mm. However, the present invention is not limited to this size, and may be appropriately changed in accordance with the number, position of the opening portion 1, the size of the body fluid treatment article 1, and the like. A spacer 5 is disposed between the first sheet 12 and the support 40. For the case of 201103507, for example, a fibrous sheet, a foamed plastic, a paper material or the like can be used as the spacer 50'. The spacer 50 has a substantially elliptical shape and covers an area of the opening portion 11 formed by all the plural numbers, so that the longitudinal direction of the longitudinal direction is γ-induced and the direction of the minor axis is aligned with the lateral direction X. The spacer 50 includes a spacer upper surface 5' on the side of the first sheet 12 and a spacer lower surface 52 on the side of the second sheet 3, the spacer upper surface 51 abuts the first sheet 12, and the spacer 52 The contact body 40 is brought into contact with each other by a joining means such as an adhesive. In the spacer 50, a spacer opening 53 penetrating from the upper surface 5b of the spacer toward the spacer lower surface 52 is formed corresponding to the opening portion 1 1. The valve body 30 is disposed in the spacer opening 53, respectively. As the support 40, for example, a liquid permeable fibrous nonwoven fabric can be used. Between the first sheet 12 and the support 40, a space 15 is formed by the spacer opening 53. The valve body 30 is in this space 15 and is supported to be movable in the thickness direction of the spacer 50. That is, the diameter of the spacer opening 53 is larger than the diameter of the opening portion 1 1 and larger than the diameter of the valve body 30. The thickness of the spacer 50 is larger than that of the valve body 30. Specifically, the valve body 30 has a thickness of about 0.5 mm, and the spacer 50 has a thickness of about 2 mm. Since the support body 40 is joined to the lower surface 52 of the spacer, the valve body 30 does not fall into the inside of the housing 10. Further, the valve body 30 restricts the movement in the longitudinal direction Y and the lateral direction X by the peripheral wall of the spacer 50, the peripheral edge 14 of the opening, and the support 40. When the body fluid such as urine is discharged to the opening portion 1 of the body fluid treatment article 1, the valve body 30 is pressed toward the support body 40 by the weight of the body fluid, and the valve body lower surface 32 is supported by the support body 40 to be supported. . The peripheral edge 14 of the opening is separated from the upper surface 31 of the valve -10 - 201103507, and the body fluid flows into the space 15 through the periphery of the valve body 30. The body fluid flows into the inside of the container "0" through the support 40. Since the container 10 is liquid-impermeable and has a bag shape, the body fluid is held in the container 10 in a state in which the body fluid is held in the container 10, as shown in Fig. 4, the container body 1 is turned upside down. In this case, the body fluid moves toward the opening 1 1 , and the valve body lower surface 32 of the valve body 30 is pressed by the body fluid that has passed through the support body 40 and moves toward the first sheet 12 side. The valve body upper surface 31 of the valve body 30 is in contact with the opening peripheral edge 14. Since the valve body 30 is pressed by the body fluid, it can be intimately contacted with the peripheral edge 14 of the opening, and the body fluid can be prevented from flowing out of the outside of the container 10. Further, since the valve body 30 has a smaller specific gravity than the body fluid, it can float in the body fluid. When the container 10 is in the state shown in FIG. 2, the body such as urine is held in the container 10. Since the valve body 30 floats in the body fluid, the body fluid is opened before flowing out of the opening portion 1 1 . The portion 1 1 is closed by the valve body 30. Therefore, even in this case, it is possible to prevent the body fluid from flowing out of the outside of the container 10. When a slight body fluid remains between the valve body 30 and the first sheet 12, the valve body upper surface 31 and the opening peripheral edge 14 of the first sheet 12 are more watertightly contacted by the surface tension of the body fluid. The effect of preventing the body fluid inside the container 10 from flowing out can be improved. Since the plurality of openings 11 and the backflow prevention means 20 are formed, the valve body 30 cannot be moved in the thickness direction for some reason, and the comprehensive function of the collar region of the backflow prevention means 20 can be avoided. . Moreover, the plurality of openings 11 and the backflow prevention means 20 can be formed in a wide range as needed, and the body fluid can be reliably accommodated inside the container 10. Figs. 5 to 7 show an example of the article for wearing -11 - 201103507 including the body fluid treatment article 1 described above. The disposable diaper 2 will be described as an example of the article for wearing. Fig. 5 is a perspective view of the disposable diaper 2, and Fig. 6 is a plan view of the disposable diaper 2 when the both side edges of Fig. 5 are released. Fig. 7 is a sectional view taken along line VII-VII of Fig. 6. In Figs. 5 and 6, a part of the elastic member is stretched to withstand the contraction force for the purpose of explanation, and the disposable diaper 2 is held in a planar shape. The disposable diaper 2 includes a main body 60 and a liquid absorbing structure 70. The main body 60 includes a waist region surrounding the longitudinal direction Y, a rear waist region 62, and a crotch region 63 between the front and rear waist regions 61, 62, and has a vertical imaginary center that divides the dimension of the lateral direction X into two. The line PP and the dimension of the longitudinal direction Y are divided into two-dimensional imaginary center line QQ. The main body 60 is a main body 60 including a spacer 64 formed on the body side, an outer surface 65 on the opposite side to the garment side, a main body side edge 66 extending in the longitudinal direction Y, and a main body front and rear end line 67 extending in the lateral direction X. , 68. The main body side edges 66 are curved toward the imaginary center line P-P at the crotch region 63. The spacer 64 and the outer surface 65 may be a conventional material in the technical field to which the present invention pertains, such as a liquid permeable fiber nonwoven fabric. Along the side edges 66 of the body, at least in the crotch region 63, the foot elastics 82 are retractably mounted in an extended state. The foot elastic body 82 is between the spacer 64 and the outer surface 65, and is joined to at least one of them. Along the front and rear end edges 67, 68 of the main body, the waist elastic body 81 having a wide width is contracted in the lateral direction X in an extended state. The waist elastic 81 1 is joined to the side of the pad 64 closer to the body. As the waist elastic body 81 and the leg elastic body 82, a stretchable fiber nonwoven fabric can be used. However, it is not limited to -12-201103507 stretchable fiber nonwoven fabric, and a conventional elastic body of such an article can be used. As shown in Fig. 5, the main body side edges 66 are joined to each other at the front and rear waist regions 61, 62 to form a pants-type disposable diaper 2. In the main body 60, a main body opening 69 through which the spacer 64 and the outer surface 65 penetrate in the thickness direction is formed at least in the crotch region 63. In this embodiment, the main body opening 69 is formed in a slightly elliptical shape extending from the crotch region 63 toward the front and rear waist regions 61, 62. Between the spacer 64 and the outer surface 65, a top sheet 17 is disposed to seal the main body opening 69. In the top sheet 17, a slightly circular top opening 18 is formed at a position closer to the side of the front end edge 67 of the main body than the horizontal imaginary center line Q-Q. The top opening 18 penetrates the top sheet 17 in the thickness direction thereof and has an area smaller than the opening area of the main body opening 69. On the dressing side of the outer surface 65, a liquid absorbing structure 70 is formed so as to cover the main body opening 69, that is, to overlap the top sheet 17. The liquid-absorbent structure 70 includes a garment side on the body side and the opposite side, a liquid-absorbent core member 71, and a cover sheet 72 covering the liquid-absorbent core member 71, which is more than the transverse imaginary center line QQ. A liquid suction opening 74 is formed in a position close to the front end edge 67 of the main body so as to overlap the top opening 18. The liquid absorbing opening 74 penetrates the liquid-absorbent core member 7 1 in the thickness direction thereof. The liquid-absorbent core material 71 is a conventional material in the technical field to which the invention belongs, such as a mixture of fluff pulp and superabsorbent polymer particles, and the coated sheet 72 is a liquid-diffusing thin paper or the like. Conventional materials in the technical field. The body fluid treatment article 1 is attached to the dressing side of the liquid-absorbent structure 7A, and the cover sheet 73 is attached to the dressing side. As the cover sheet 73, a liquid-impermeable film or the like can be used. Further, in the position of -13-201103507 of the cover sheet 73 closer to the dressing side, a fiber non-woven fabric may be disposed to enhance the touch of the skin. The body fluid processing product 1 disposed between the liquid-absorbent structure 70 and the cover sheet 73 has the first sheet 12 on the side of the liquid-absorbent structure 70 and the second sheet 13 on the side of the cover sheet 73. The opening portion 1 1 of the body fluid treatment article 1 is disposed closer to the body leading end edge 67 than the lateral imaginary center line Q-Q, and is exposed to the body side via the liquid suction opening 74 and the top opening 18 of the liquid absorbing structure 70. The opening portion 1 1 is located at a position corresponding to the wearer's external device. In the disposable diaper 2 described above, when the wearer urinates, the urine is stored in the container 10 of the body fluid treatment article 1 from the opening portion 1 1 . When the body fluid treatment article 1 is in the state of FIG. 2, the urine is received by the container 10 through the periphery of the valve body 30, and when the wearer lie down or squats to the state of FIG. 4, the valve body 30 and The peripheral edge 14 of the opening of the first sheet 12 is in watertight contact, and it is possible to prevent the urine contained in the container 10 from flowing back toward the wearer side. Further, when the wearer sits down to apply the body pressure to the body fluid treatment article 1, the water level of the urine contained in the container 10 rises in the container 10, but the specific gravity of the valve body 30 is higher than that of the urine. Since the body fluid is smaller, it can float in the urine, and as a result, the valve body upper surface 21 of the valve body 30 comes into contact with the peripheral edge 14 of the opening of the first sheet 12 before the urine flows out of the container 10. Therefore, it is also possible to prevent the urine from flowing back toward the body side in this case. Since the urine can be prevented from flowing back from the body fluid treatment article 1, it is possible to suppress leakage of urine from the disposable diaper 2. Even if the urine is discharged from the opening 1 1 of the body fluid treatment article 1 or dripped from the container 10, the liquid-absorbent structure 7 is present around the opening 11, so that it can be absorbed by the liquid-absorbent structure 70. Leaked urine. Therefore, leakage of urine from the disposable diaper 1 can be further suppressed. Further, although the space 15 of the holding valve-14-201103507 body 30 is formed by the spacer 50, the size of the spacer 50 in the thickness direction can be reduced by forming the valve body into a sheet shape. Can reduce the discomfort to the wearer. In the embodiment, the liquid-absorbent structure 70 of the disposable diaper 2 is formed with a liquid-absorbent opening 74' for exposing the opening of the body fluid treatment article 1 to the liquid-absorbent opening 74. 1 is located on the body side of the liquid-absorbent structure 7〇. In this case, the body fluid treatment article 1 can be formed between the main body 60 and the liquid absorbing structure 70. A body opening 69 is formed in the body 60, but it is not always necessary to form the body opening 69. In this case, at least the portion where the opening portion 1 1 of the body fluid treatment article 1 is placed is made liquid-permeable, and the body fluid such as urine can be transmitted through the body fluid treatment article 1 located on the dressing side of the main body 60. Further, the body fluid treatment article 1 may be formed on the body side of the main body 60. In any case, it is sufficient that the body fluid such as urine can be accommodated in the container 10 through the opening 1 1 of the body fluid treatment article 1. The container 10 is liquid-impermeable, but is not limited to liquid-impermeable. If it is a liquid permeable body that can be accommodated through the opening 1 1 , it may be liquid permeable or may contain a body fluid such as a liquid absorbing core material. However, in the case where the liquid permeable sheet is used as the first sheet 12, in order to achieve watertight contact between the peripheral edge 14 of the opening and the valve body 30, at least the peripheral edge 14 of the opening is required to be liquid-impermeable. For example, when a liquid permeable fibrous nonwoven fabric is used as the first sheet 12, it can be realized by adhering a liquid-impermeable film to the peripheral edge 14 of the opening, and also applying hydrophilic treatment to the hydrophobic fiber nonwoven fabric. When the first sheet 12 is used, it may be realized by not performing the hydrophilic treatment only on the peripheral edge 14 of the opening. -15-201103507 [Embodiment 2] Figs. 8 and 9 are views showing a second embodiment of the present invention, and Fig. 8 is a partial plan view of the body fluid treatment article 1, which is partially cut away for the sake of explanation, and Fig. 9 is Fig. 8 Sectional view of the IX-IX line. In the second embodiment, the body fluid treatment article 1 is not characterized in that the opening portion 1 1 is directly formed on the first sheet 12, and the shape retaining member 90 having the opening portion 1 is additionally provided. Other components other than this feature are the same as those in the first embodiment, and detailed descriptions thereof will be omitted for the same components. In the first sheet 12 on which the accommodating portion 10 is formed, a mounting opening 16 for mounting the shape retaining member 90 is formed. On the side of the second sheet 13 on which the opening 16 is attached, the shape retaining member 90 in which the opening portion is formed is joined via a bonding means such as an adhesive. The shape retaining member 90 can have a higher rigidity than the first sheet 12, for example, a fiber sheet, a foamed plastic, a paper material or the like having a higher shape retention property. The shape retaining member 90 includes a conformal upper surface 91 on the side of the first sheet 12 and a conformal lower surface 92 on the side of the second sheet 13, and the conformal upper surface 91 is joined to the periphery of the mounting opening 16 of the first sheet 12, and The lower surface 92 is joined to the spacer upper surface 51 of the spacer 50. By forming the opening 11 in the shape retaining member 90 and forming it in the first sheet 1 2, the shape of the opening 1 1 can be maintained as compared with the case where the opening 1 1 is formed directly in the first sheet 1 2 . When the opening portion 1 1 is distorted and the shape thereof is collapsed, the valve body 30 is less likely to be in close contact with the peripheral edge 14 of the opening portion, and there is a possibility that a gap is formed therebetween. When a gap is generated, there is a possibility that body fluid such as urine leaks from the place, but by maintaining the shape of the opening portion 1 -16-201103507, the valve body 30 can be more reliably and watertightly contacted, and body fluid can be prevented. leakage. In this embodiment, the peripheral edge 14 of the opening is formed by the conformal underside 91 of the conformal member 90. Since the opening portion 11 is formed in the shape retaining member 90, it can be joined to the first sheet 1 2, so that the forming operation can be performed more easily than when the opening portion 1 1 is directly formed in the first sheet 12. In other words, since the shape retaining member 90 has a narrower area than the first sheet 1 2 and has high rigidity, it is easy to handle, and the opening portion 1 is also easily formed. Further, although the shape retaining member 90 and the spacer 50 are made as different members, the two members can be formed by the same member. The shape retaining member 90 is attached to the second sheet 13 side of the first sheet 12, that is, the inside of the container body 1 but may be attached to the outer side of the housing 10 on the opposite side. Such a body fluid treatment article 1 can be used for the wearing article such as the disposable diaper 2 as in the first embodiment. [Embodiment 3] Figs. 10 and 11 are views showing a third embodiment of the present invention, and Fig. 10 is a cross-sectional view showing a portion of the plan view of the body fluid treatment article 1. Fig. 11 is a cross-sectional view taken along line ΧΙ-ΧΙ of Fig. 10. In the third embodiment, one opening portion 11 is formed in the first sheet 12, and the other constituent elements are the same as those in the first embodiment. Detailed descriptions of the same components will be omitted. In the first sheet 12, one opening portion 11 is formed. A valve body 30 is formed between the first sheet 12 and the second sheet 13 so as to be separable from the peripheral edge 14 of the opening. Since the opening portion 1 1 is formed as one portion, the opening portion can be easily formed, and -17-201103507 and the valve body 30 attached to the opening portion 1 1 are also required. Therefore, the number of parts can be reduced. In the third embodiment, the opening portion 11' can be formed in the conformal member in the same manner as in the second embodiment, and the conformal member can be attached to the first sheet 12. Further, such a body fluid treatment article 1 can be used for the disposable diaper 2 as in the first embodiment.
