Description

吸收性物品Absorbent article

本創作係關於一種經期衛生棉等吸收性物品(女性用吸收性物品)。This creation is about an absorbent article such as menstrual cotton (absorbent for women).

先前，於經期衛生棉等吸收性物品中，眾所周知有為了提高防漏性或穿著性，而於其肌膚對向面，形成正面片材及吸收體朝向背面片材側而一體地凹陷之槽。又，作為適於就寢時等長時間使用之經期衛生棉，眾所周知有於縱向(衛生棉長度方向)之前方(排泄部對向部)具備側翼部，於後方具備後方翼部者。In the absorbent articles such as menstrual napkins, it has been known that in order to improve leakproofness or wearability, a groove in which the front sheet and the absorbent body are integrally recessed toward the back sheet side are formed on the skin facing surface. In addition, it is known that the menstrual sanitary napkin which is suitable for use for a long period of time, such as when sleeping, has a side flap portion in the longitudinal direction (the longitudinal direction of the tampon), and a rear wing portion in the rear.

關於具備側翼部及後方翼部、且於肌膚對向面形成有槽之經期衛生棉，例如於日本專利特開2009-261777號公報中記載有如下者：於穿著時配置於穿著者之臀部側的衛生棉之後部之肛門對向部周邊區域，以使槽於縱向中斷的方式設置有未配置槽之槽非配設部。該肛門對向部周邊區域形成為將自大概對向於穿著者之肛門之部分起包含其稍微背側上部在內之縱向劃分而成之區域，根據日本專利特開2009-261777號公報之圖1之記載，其係於後方翼部之前方側處於比較接近與側翼部之交界之位置。根據日本專利特開2009-261777號公報，於穿著衛生棉時該槽非配設部朝向穿著者之肌膚適當隆起而服貼，故而可抑制經血等洩漏。A menstrual sanitary napkin having a side flap portion and a rear wing portion and having a groove formed on the opposite surface of the skin is described in Japanese Laid-Open Patent Publication No. 2009-261777, which is laid on the buttock side of the wearer when worn. The peripheral portion of the anal door opposite portion of the tampon is provided with a groove non-arrangement portion in which the groove is not interrupted in the longitudinal direction. The peripheral region of the anal portion is formed in a longitudinally divided region from a portion opposite to the anus of the wearer, including a slightly back upper portion thereof, according to the Japanese Patent Laid-Open Publication No. 2009-261777. In the description of 1, the front side of the rear wing portion is located closer to the boundary between the side wing portions. According to Japanese Laid-Open Patent Publication No. 2009-261777, when the sanitary napkin is worn, the non-arrangement portion of the groove is appropriately swelled toward the skin of the wearer, so that leakage of menstrual blood or the like can be suppressed.

又，於專利第4252439號公報中記載有如下情況：為了提高穿著衛生棉時之後方翼部之形狀穩定性、防止經血等洩漏，而使後方翼部 之俯視形狀成為寬度尺寸於縱向之前方為最大且隨著朝向後方而寬度尺寸(橫向之長度)逐漸變小的形狀。於專利第4252439號公報中記載之衛生棉中，於一對後方翼部各自之非肌膚對向面，形成有將該後方翼部固定於穿著之衣服的縱長的後方黏著部。又，根據專利第4252439號公報之圖1及圖5之記載，於衛生棉之後方部之肌膚對向面之左右兩側部，形成有沿著縱向延伸之一對槽、及位於較一對該槽更靠橫向外側的位置且沿著縱向延伸之一對外側槽，該一對外側槽於較上述後方黏著部更靠縱向前方側的位置中斷。但，於專利第4252439號公報中，未對該外側槽之中斷部之技術性意義等進行特別記載。Further, Japanese Patent No. 4252439 discloses a case where the rear wing portion is formed in order to improve the shape stability of the wing portion after wearing the sanitary napkin and prevent leakage of menstrual blood or the like. The shape of the plan view is a shape in which the width dimension is the largest in the longitudinal direction and the width dimension (the length in the lateral direction) gradually decreases toward the rear. In the sanitary napkin described in Japanese Patent No. 4252439, a long rear adhesive portion that fixes the rear wing portion to the worn clothes is formed on each of the pair of rear wing portions on the non-skin opposing surface. Further, according to FIG. 1 and FIG. 5 of Japanese Patent No. 4252439, a pair of grooves extending in the longitudinal direction and a pair are formed on the left and right sides of the skin facing surface of the sanitary napkin. The groove is further laterally outward and extends in the longitudinal direction to the outer groove, and the pair of outer grooves are interrupted at a position closer to the longitudinal front side than the rear adhesive portion. However, in Patent No. 4252439, the technical meaning of the interruption portion of the outer groove is not specifically described.

圖5係作為本創作之吸收性物品之一實施形態之經期衛生棉之另一例之相當於圖2之圖。Fig. 5 is a view corresponding to Fig. 2 showing another example of menstrual sanitary napkin as an embodiment of the absorbent article of the present invention.

以經期衛生棉為代表之此種吸收性物品通常穿著於短褲等穿著之衣服上，且穿在胯下部。然而，該胯下部由於步行等身體之活動，而容易大幅變動，從而經期衛生棉容易產生褶皺。此處所言之褶皺並非以服貼性等之特性提高之目的而有意地產生之變形，係非有意之變形，其係指會成為服貼性之降低或側漏等之不良情況之原因者。尤其，於具備後方翼部之經期衛生棉中，若於其肌膚對向面形成有自排泄部對向部遍及後方部而於縱向連續之槽，則於排泄部對向部產生之褶皺藉由該槽而向後方部傳遞，從而有誘發後方翼部之褶皺或捲縮之虞。排泄部對向部為由穿著衛生棉時穿著者之大腿部夾持之部位，故而容易自橫向受到外力(壓縮力)，與後方部相比容易產生褶皺(變形)。Such absorbent articles represented by menstrual sanitary napkins are usually worn on clothes worn on shorts and the like, and are worn on the lower part of the crotch. However, the lower part of the crotch is easily changed greatly due to the movement of the body such as walking, so that the sanitary napkin is prone to wrinkles. The wrinkles described herein are not intentionally deformed by the purpose of improving the characteristics such as the conformity, and are unintentional deformations, which means that the defects may be caused by a decrease in the conformability or a side leakage. In particular, in the menstrual sanitary napkin having the rear wing portion, when the skin facing surface is formed with a groove continuous in the longitudinal direction from the rear portion of the excretory portion, the wrinkles generated in the opposing portion of the excretory portion are caused by The groove is transmitted to the rear portion, and the wrinkles or curls of the rear wing portion are induced. Since the opposing portion of the excretory portion is a portion that is held by the thigh portion of the wearer wearing the sanitary napkin, it is easy to receive an external force (compression force) from the lateral direction, and wrinkles (deformation) are likely to occur as compared with the rear portion.

相對於此，如日本專利特開2009-261777號公報及專利第4252439號公報中所記載般，若自排泄部對向部遍及後方部而於縱向延伸之槽於中途中斷，則於排泄部對向部產生之褶皺不會傳遞至該中斷部的縱向後方，故而難以產生後方翼部之褶皺或捲縮。然而，若於沿著縱向延伸於後方部之槽簡單地設置中斷部，則位於該中斷部之側方之部分(衛生棉之後方部之橫向中央部)於穿著衛生棉時朝向穿著者之肌膚側 大幅隆起，其結果，有導致位於該隆起部之側方之部分(後方翼部)之褶皺或捲縮之虞。仍然未提供難以產生後方部之褶皺或捲縮，具有可追隨穿著者之各種活動或姿勢之變化之高身體追隨性之吸收性物品。On the other hand, as described in Japanese Patent Laid-Open Publication No. 2009-261777 and No. 4252439, if the groove extending in the longitudinal direction from the opposing portion of the excretory portion is interrupted in the middle, the excretion portion is The wrinkles generated in the portion are not transmitted to the longitudinal rear side of the interruption portion, so that it is difficult to cause wrinkles or curling of the rear wing portion. However, if the interruption portion is simply provided in the groove extending in the longitudinal direction in the rear portion, the portion located on the side of the interruption portion (the lateral central portion of the rear portion of the sanitary napkin) faces the wearer's skin when wearing the sanitary napkin. side As a result, the bulge is large, and as a result, there is a wrinkle or curl which is located on the side (the rear wing portion) of the ridge portion. There is still no absorbent article that is difficult to produce wrinkles or curls at the rear, and has high body followability that can follow changes in various activities or postures of the wearer.

因此，本創作係關於一種難以產生後方部之褶皺或捲縮、具有高身體追隨性之吸收性物品。Therefore, the present invention relates to an absorbent article which is difficult to produce wrinkles or curls in the rear portion and has high body followability.

本創作係一種吸收性物品，其包括吸收性本體，且具有相當於穿著者之前後方向之縱向及與其正交之橫向，上述吸收性本體具備液體保持性之吸收體、以及配置於該吸收體之肌膚對向面側之正面片材及配置於該吸收體之非肌膚對向面側之背面片材，且具有：排泄部對向部，其於穿著時對向於穿著者之排泄部而配置；及後方部，其配置於較該排泄部對向部更靠穿著者之背側的位置；具備自上述吸收性本體中之沿著上述後方部之縱向之兩側部各自而向橫向外側外延之一對後方翼部，且於一對該後方翼部各自之非肌膚對向面，形成有將該後方翼部固定於穿著之衣服的縱長之後方黏著部，於上述吸收性本體之肌膚對向面，形成有上述正面片材及上述吸收體朝向上述背面片材側而一體地凹陷而成之線狀槽，該線狀槽包含縱向延伸於上述後方部之縱槽、及於該後方部位於較該縱槽靠橫向內側之內側槽，上述縱槽具有於縱向中斷之中斷部，該中斷部存在於由2條假想直線夾持之後方部特定區域內，且上述內側槽存在於該後方部特定區域內，該2條假想直線係通過上述後方黏著部之縱向前後端各自且沿著橫向延伸。The present invention relates to an absorbent article comprising an absorbent body having a longitudinal direction corresponding to a longitudinal direction of a wearer and a transverse direction orthogonal thereto, the absorbent body having a liquid retaining property, and an absorbent body disposed thereon The front sheet on the opposite side of the skin and the back sheet disposed on the non-skin facing side of the absorbent body, and having an excretion portion facing portion that faces the excretory portion of the wearer when worn And a rear portion disposed at a position closer to the back side of the wearer than the opposing portion of the drain portion; and provided laterally outward from each of the two sides of the absorbent body along the longitudinal direction of the rear portion One of the extensions is opposite to the rear wing portion, and the non-skin opposing surface of each of the pair of rear wing portions is formed with a longitudinally long rear adhesive portion that fixes the rear wing portion to the worn garment, and is disposed on the absorbent body a linear groove formed integrally with the front surface sheet and the absorbent body toward the back surface sheet side, wherein the linear groove includes a longitudinal groove extending longitudinally in the rear portion, and The square portion is located at an inner side groove on the inner side of the longitudinal groove, and the longitudinal groove has an interruption portion interrupted in the longitudinal direction, and the interruption portion exists in a specific region of the square portion after being sandwiched by two imaginary straight lines, and the inner groove is present in the inner groove In the specific region of the rear portion, the two imaginary straight lines extend through the longitudinal front and rear ends of the rear adhesive portion and extend in the lateral direction.

本創作之吸收性物品難以產生後方部(例如經期衛生棉中之後方翼部)之褶皺或捲縮，具有高身體追隨性，難以產生側漏。The absorbent article of the present invention is difficult to produce wrinkles or curls in the rear portion (for example, the rear wing portion of the menstrual sanitary napkin), has high body followability, and is difficult to generate side leakage.

以下，基於作為本創作之吸收性物品之較佳之一實施形態之經期衛生棉參照圖式對本創作之吸收性物品進行說明。如圖1及圖2所示，本實施形態之衛生棉1包括吸收性本體5，且具有相當於穿著者之前後方向之縱向X及與其正交之橫向Y，上述吸收性本體5具備液體保 持性之吸收體4、以及配置於該吸收體4之肌膚對向面側之正面片材2及配置於該吸收體4之非肌膚對向面側之背面片材3。Hereinafter, the absorbent article of the present invention will be described based on a menstrual sanitary napkin as a preferred embodiment of the absorbent article of the present invention with reference to the drawings. As shown in Fig. 1 and Fig. 2, the sanitary napkin 1 of the present embodiment includes an absorbent body 5 having a longitudinal direction X corresponding to the front and rear directions of the wearer and a transverse direction Y orthogonal thereto, and the absorbent body 5 is provided with a liquid protection. The absorbent body 4 and the front sheet 2 disposed on the skin facing surface side of the absorbent body 4 and the back sheet 3 disposed on the non-skin opposing surface side of the absorbent body 4.

再者，於本說明書中，肌膚對向面係吸收性物品或其構成部材(例如吸收性本體5)中之吸收性物品之穿著時朝向穿著者之肌膚側之面，非肌膚對向面係吸收性物品或其構成部材中之吸收性物品之穿著時朝向與肌膚側相反側(穿著之衣服側)之面。又，縱向X與沿著吸收性物品(吸收性本體)之長邊之方向(長度方向)一致，橫向Y與吸收性物品(吸收性本體)之寬度方向(與長度方向正交之方向)一致。Further, in the present specification, the absorbent article in the face-to-face absorbent article or the constituent member (for example, the absorbent body 5) is worn toward the skin side of the wearer, and the non-skin facing surface is worn. The absorbent article in the absorbent article or the constituent member thereof faces the side opposite to the skin side (the side of the garment to be worn) when worn. Further, the longitudinal direction X coincides with the direction (longitudinal direction) along the long side of the absorbent article (absorbent body), and the transverse direction Y coincides with the width direction (direction orthogonal to the longitudinal direction) of the absorbent article (absorbent body). .

吸收性本體5於縱向X具有：排泄部對向部B，其於穿著時對向於穿著者之排泄部而配置；前方部A，其於穿著時配置於較排泄部對向部B更靠穿著者之腹側(前側)的位置；及後方部C，其於穿著時配置於較排泄部對向部B更靠穿著者之背側(後側)的位置。此處所言之「穿著時」，係指維持通常之適當之穿著位置(該吸收性物品之正確之穿著位置)之狀態，不包含處於吸收性物品自該穿著位置偏移之狀態之情形。The absorbent body 5 has a drain portion facing portion B that is disposed opposite to the wearer's excretion portion when worn, and a front portion A that is disposed closer to the excretory portion facing portion B when worn. The position of the ventral side (front side) of the wearer and the rear portion C are disposed at a position closer to the back side (rear side) of the wearer than the vent portion B toward the rear portion B when worn. The term "when worn" as used herein refers to a state in which the usual proper wearing position (the correct wearing position of the absorbent article) is maintained, and the state in which the absorbent article is displaced from the wearing position is not included.

衛生棉1除了具有吸收性本體5以外，進而具有：一對側翼部7、7，其自吸收性本體5中之沿著排泄部對向部B之縱向X之兩側部各自而向橫向Y之外側外延；及一對後方翼部8、8，其自吸收性本體5中之沿著後方部C之縱向X之兩側部各自而向橫向Y之外側外延。如此之具有後方翼部之經期衛生棉適於就寢等時長時間使用，作為夜用之經期衛生棉特別有用。The sanitary napkin 1 has, in addition to the absorbent body 5, a pair of side flap portions 7, 7 which are respectively in the lateral direction of the both sides of the longitudinal direction X of the opposing portion B of the excretory portion in the self-absorbent body 5. The outer side extensions; and a pair of rear wing portions 8, 8 are respectively extended toward the outer side of the lateral direction Y from both sides of the self-absorbent body 5 along the longitudinal direction X of the rear portion C. Such a menstrual sanitary napkin having a rear wing is suitable for long-term use when sleeping, etc., and is particularly useful as a sanitary napkin for night use.

再者，於本創作之吸收性物品中，排泄部對向部於如本實施形態之衛生棉1般具有側翼部之情形時，為於吸收性物品之縱向(吸收性物品之長度方向，圖中之X方向)具有側翼部之區域(由側翼部之縱向一側之根部與另一側之根部夾持之區域)。當將吸收性物品摺疊為3折之單個包裝形態時會產生2條折曲線(未圖示)，不具有側翼部之吸收 性物品中之排泄部對向部即為與自該吸收性物品之縱向之前端數起由第1折曲線與第2折曲線包圍之區域相同或較該區域更窄之區域，該2條折曲線將該吸收性物品於橫向(吸收性物品之寬度方向，圖中之Y方向)橫切。Further, in the absorbent article of the present invention, when the opposing portion of the excretory portion has a side flap portion as in the sanitary napkin 1 of the present embodiment, it is in the longitudinal direction of the absorbent article (the longitudinal direction of the absorbent article, In the X direction), the region having the side flaps (the region sandwiched by the root portion of the longitudinal side of the side flap portion and the root portion of the other side). When the absorbent article is folded into a single package form of 3 fold, two fold curves (not shown) are generated, and there is no absorption of the side flaps. In the sexual article, the opposing portion of the excretion portion is an area which is the same as or narrower than the area surrounded by the first folding curve and the second folding curve from the front end of the longitudinal direction of the absorbent article, and the two folding portions The curve crosses the absorbent article in the lateral direction (the width direction of the absorbent article, in the Y direction in the drawing).

如圖2所示，正面片材2被覆吸收體4之整個肌膚對向面，進而自沿著吸收體4之縱向X之兩側緣向橫向Y之外側外延。另一方面，背面片材3被覆吸收體4之整個非肌膚對向面，進而自沿著吸收體4之縱向X之兩側緣向橫向Y之外側外延，與下述側片材10一起形成側翼部6。背面片材3與側片材10係於自沿著吸收體4之縱向X之兩側緣之外延部，藉由接著劑、熱密封、超音波密封等公知之接合方法而相互接合。正面片材2及背面片材3各自與吸收體4之間亦可藉由接著劑而接合。As shown in Fig. 2, the front sheet 2 covers the entire skin facing surface of the absorbent body 4, and is further extended from the both side edges of the longitudinal direction X of the absorbent body 4 to the outer side of the lateral direction Y. On the other hand, the back sheet 3 covers the entire non-skin opposing surface of the absorbent body 4, and is further extended from the both side edges of the longitudinal direction X of the absorbent body 4 to the outer side of the lateral direction Y, and is formed together with the side sheet 10 described below. Flanking portion 6. The back sheet 3 and the side sheet 10 are joined to each other from the outer side edges of the longitudinal direction X of the absorbent body 4, and are joined to each other by a known joining method such as an adhesive, heat sealing, or ultrasonic sealing. The front sheet 2 and the back sheet 3 may be joined to the absorber 4 by an adhesive.

如圖2所示，本實施形態中之吸收體4包括吸收性片材401~403之積層體，如圖1及圖2所示，於排泄部對向部B具有中高部42。吸收體4具有於2片吸收性片材401、402間夾持有另一吸收性片材403之構造，該另一吸收性片材403配置於中高部42。中高部42僅形成於排泄部對向部B，而不形成於前方部A及後方部C。如圖2所示，中高部42係構成吸收體4之吸收性片材之積層片數較位於其周圍之部分更多、且厚度更大之部分。因此，衛生棉1係於排泄部對向部B形成有向正面片材2側(衛生棉1之肌膚對向面側)突出之隆起部。又，吸收體4具有形成吸收體4之外形之主吸收體40、及重疊配置於主吸收體40之一部分且較主吸收體40小型之輔助吸收體41。主吸收體40包括於俯視時呈角部帶弧度之大致矩形形狀且自前方部A經過排泄部對向部B遍及後方部C而延伸之2片形狀相同大小相同的吸收性片材401、402；輔助吸收體41於俯視時為大致矩形形狀，且自排泄部對向部B遍及其附近之後方部C而配置。輔助吸收體41係將1片吸收性片材403摺疊而形 成2層構造者，且配置於構成主吸收體40之2片吸收性片材401、402間。於中高部42，配置有該輔助吸收體41(將1片吸收性片材403摺疊而成為複數層之構造者)。藉由於主吸收體40之一部分配置輔助吸收體41，可使吸收體4之一部分之吸收容量容易且有效率地增大。輔助吸收體41可並非配置於構成主吸收體40之2片吸收性片材401、402間，而既可積層於構成主吸收體40之上側之吸收性片材401之肌膚對向面側，亦可積層於構成主吸收體40之下側之吸收性片材402之非肌膚對向面側。又，吸收性片材間既可不接合，亦可藉由稀疏地散佈之接著劑等而接著。As shown in Fig. 2, the absorbent body 4 of the present embodiment includes a laminate of the absorbent sheets 401 to 403. As shown in Figs. 1 and 2, the absorbent portion 4 has a middle portion 42 at the opposing portion B of the excretion portion. The absorber 4 has a structure in which another absorbent sheet 403 is sandwiched between two sheets of absorbent sheets 401 and 402, and the other absorbent sheet 403 is disposed in the middle-high portion 42. The middle portion 42 is formed only in the excretion portion opposing portion B, and is not formed in the front portion A and the rear portion C. As shown in Fig. 2, the middle-high portion 42 is a portion in which the number of laminated sheets of the absorbent sheet constituting the absorbent body 4 is larger than that of the portion around the absorbent sheet. Therefore, the sanitary napkin 1 is formed with a raised portion that protrudes toward the front sheet 2 side (the skin facing surface side of the sanitary napkin 1) in the excretion portion facing portion B. Further, the absorber 4 has a main absorber 40 which is formed in a shape other than the absorber 4, and an auxiliary absorber 41 which is disposed to overlap one of the main absorbers 40 and which is smaller than the main absorber 40. The main absorbent body 40 includes two absorbent sheets 401 and 402 having the same rectangular shape and having the same rectangular shape extending from the front portion A through the excretory portion facing portion B over the rear portion C in a plan view. The auxiliary absorber 41 has a substantially rectangular shape in a plan view, and is disposed from the rear portion B to the rear portion C of the vicinity of the drain portion B. The auxiliary absorbent body 41 is formed by folding one sheet of the absorbent sheet 403 The two-layer structure is disposed between the two sheets of absorbent sheets 401 and 402 constituting the main absorber 40. In the middle-high portion 42, the auxiliary absorbent body 41 (a structure in which one sheet of the absorbent sheet 403 is folded to form a plurality of layers) is disposed. By arranging the auxiliary absorber 41 in one of the main absorbers 40, the absorption capacity of a portion of the absorber 4 can be easily and efficiently increased. The auxiliary absorber 41 may be disposed not between the two sheets of absorbent sheets 401 and 402 constituting the main absorbent body 40, but may be laminated on the skin facing side of the absorbent sheet 401 constituting the upper side of the main absorbent body 40. It is also possible to laminate the non-skin opposing side of the absorbent sheet 402 constituting the lower side of the main absorbent body 40. Further, the absorbent sheets may be joined without being joined, or may be followed by a sparsely spread adhesive or the like.

吸收體4中，中高部42之厚度較佳為0.7mm以上，更佳為1mm以上，又，較佳為5mm以下，更佳為4mm以下。更具體而言，中高部42之厚度較佳為0.7mm以上5mm以下，更佳為1mm以上4mm以下。藉由使中高部42之厚度為該範圍，而容易同時實現形成有中高部42之排泄部對向部B的良好之穿著感與高吸收性能。又，如本實施形態之衛生棉1般吸收性物品具備側翼部之情形時，容易抑制於其穿著時排泄部對向部中之吸收體之褶皺。關於中高部42以外之吸收體4之厚度，即主吸收體40(2片吸收性片材401、402之積層體)之厚度，較佳為0.3mm以上，更佳為0.5mm以上，又，較佳為3mm以下，更佳為2.5mm以下。更具體而言，自提高高吸收性能與隨著穿著者之活動之追隨性之觀點而言，主吸收體40之厚度為0.5mm以上3mm以下，進而為0.6mm以上2.5mm以下較佳。In the absorbent body 4, the thickness of the middle-high portion 42 is preferably 0.7 mm or more, more preferably 1 mm or more, further preferably 5 mm or less, and more preferably 4 mm or less. More specifically, the thickness of the middle-high portion 42 is preferably 0.7 mm or more and 5 mm or less, more preferably 1 mm or more and 4 mm or less. By setting the thickness of the middle-high portion 42 to this range, it is easy to simultaneously achieve a good wearing feeling and high absorption performance of the excretion portion opposing portion B in which the middle-high portion 42 is formed. Further, when the absorbent article of the sanitary napkin 1 of the present embodiment includes the side flap portion, it is easy to suppress the wrinkles of the absorbent body in the opposing portion of the excretion portion during wearing. The thickness of the absorber 4 other than the middle-high portion 42, that is, the thickness of the main absorber 40 (the laminate of the two sheets of the absorbent sheets 401 and 402) is preferably 0.3 mm or more, more preferably 0.5 mm or more. It is preferably 3 mm or less, more preferably 2.5 mm or less. More specifically, from the viewpoint of improving the high absorption performance and the followability with the activity of the wearer, the thickness of the main absorbent body 40 is preferably 0.5 mm or more and 3 mm or less, and more preferably 0.6 mm or more and 2.5 mm or less.

又，於吸收體4中，中高部42與其周邊部之交界或其附近之兩者之厚度差(階差)較佳為2mm以下，更佳為1.5mm以下。該目的為：於排泄部對向部B中，抑制中高部42與其周邊部分之僅存在主吸收體40之區域之交界附近之褶皺之產生。若該階差較大，則於穿著中衛生棉1追隨穿著者之活動時，為了填埋由階差所引起之間隙，結果有時會 因階差之影響而容易產生褶皺，藉由將該階差設定於上述範圍內，而抑制排泄部對向部B中之褶皺之產生之效果提高。上述吸收體4之各部之厚度可藉由下述方法而測定。Further, in the absorber 4, the thickness difference (step difference) between the intermediate portion 42 and the peripheral portion thereof or the vicinity thereof is preferably 2 mm or less, more preferably 1.5 mm or less. This object is to suppress the occurrence of wrinkles in the vicinity of the boundary between the intermediate portion 42 and the peripheral portion of the region where only the main absorber 40 is present in the opposing portion B of the excretory portion. If the step is large, when the sanitary napkin 1 follows the wearer's activity while wearing, the gap may be caused by filling the gap caused by the step difference. The wrinkles are likely to occur due to the influence of the step, and by setting the step in the above range, the effect of suppressing the occurrence of wrinkles in the opposing portion B of the excretory portion is improved. The thickness of each portion of the above-mentioned absorbent body 4 can be measured by the following method.

<吸收體之厚度之測定方法><Method for Measuring Thickness of Absorber>

將作為測定對象物之吸收體以無皺褶或折彎之方式靜置於水平之場所，測定5cN/cm2 之負載下之厚度。本創作中之厚度之測定係使用厚度計PEACOCK DIAL UPRIGHT GAUGES R5-C(OZAKI MFG.CO.LTD.製造)。此時，於厚度計之前端部與測定對象物中之測定部分之間，配置俯視時呈圓形狀或正方形狀之板(厚度為5mm左右之丙烯酸板)，以負載成為5cN/cm2 之方式調整板之大小。The absorber as the object to be measured was placed in a horizontal position without wrinkles or bending, and the thickness under a load of 5 cN/cm 2 was measured. The thickness of the present invention was measured using a thickness gauge PEACOCK DIAL UPRIGHT GAUGES R5-C (manufactured by OZAKI MFG. CO. LTD.). At this time, a plate having a circular or square shape (acrylic plate having a thickness of about 5 mm) in a plan view is placed between the end portion of the thickness gauge and the measurement portion in the measurement target, and the load is 5 cN/cm 2 . Adjust the size of the board.

如圖1所示，於吸收性本體5之肌膚對向面(正面片材2之肌膚對向面)中之沿著縱向X之兩側部，以於俯視時重疊於沿著吸收體4之縱向X之左右兩側部之方式，遍及吸收性本體5之縱向X之大致全長而配置有一對側片材10、10。一對側片材10、10分別由位於排泄部對向部B之線狀的第1接合線11與位於該第1接合線11之縱向X之前後(前方部A及後方部C)之線狀的第2接合線12而接合於吸收性本體5(正面片材2)。第1接合線11為於俯視時朝向橫向Y之外側凸出之曲線狀，第2接合線12為於俯視時以與縱向交叉之方式延伸之線狀(鋸齒狀線狀)。側片材10包括撥水性之不織布。如此，若側片材10由接合線11、12而接合於吸收性本體5之肌膚對向面(正面片材2)，則如圖2所示，於較接合線11、12更靠橫向Y之內側的位置，形成由側片材10與正面片材2而劃分形成之空間部P。該空間部P朝向吸收性本體5之橫向Y之中央開口，故而自橫向Y之中央向外側流動之經血等排泄液被收納於空間部P，結果可有效地防止排泄液之洩漏。As shown in FIG. 1 , on both sides of the longitudinal direction X in the skin facing surface of the absorbent body 5 (the skin facing surface of the front sheet 2 ), it is superposed on the absorbent body 4 in plan view. A pair of side sheets 10 and 10 are disposed over substantially the entire length of the longitudinal direction X of the absorbent body 5 in the left and right side portions of the longitudinal direction X. The pair of side sheets 10 and 10 are respectively formed by a line of the first bonding wire 11 located in the opposing portion B of the drain portion and before and after the longitudinal direction X of the first bonding wire 11 (front portion A and rear portion C) The second bonding wire 12 is joined to the absorbent body 5 (front sheet 2). The first bonding wire 11 has a curved shape that protrudes toward the outer side in the lateral direction Y in a plan view, and the second bonding wire 12 has a linear shape (a zigzag shape) extending in a longitudinal direction so as to intersect the vertical direction. The side sheet 10 includes a water-repellent non-woven fabric. As described above, when the side sheet 10 is joined to the skin facing surface (front sheet 2) of the absorbent body 5 by the bonding wires 11 and 12, as shown in FIG. 2, it is closer to the lateral direction than the bonding wires 11 and 12. At the inner side position, a space portion P defined by the side sheet 10 and the front sheet 2 is formed. Since the space portion P is opened toward the center of the lateral direction Y of the absorbent body 5, excretory fluid such as menstrual blood flowing outward from the center of the lateral direction Y is accommodated in the space portion P, and as a result, leakage of the excretory liquid can be effectively prevented.

如圖1所示，側翼部6於排泄部對向部B朝向橫向Y之外側大幅突出，藉此，於吸收性本體5之沿著縱向X之左右兩側，延伸設置有一 對側翼部7、7。又，側翼部6亦於後方部C朝向橫向Y之外側大幅突出，藉此，於本體5之沿著縱向X之左右兩側，延伸設置有一對後方翼部8、8。又，如圖1所示，正面片材2及背面片材3自吸收體4之縱向X之前端及後端各自而向縱向X之外側外延，於該等外延部中，藉由接著劑、熱密封、超音波密封等公知之接合方法而相互接合，從而形成端封部。As shown in FIG. 1 , the side flap portion 6 largely protrudes toward the outer side of the lateral direction Y of the excretory portion opposing portion B, whereby one of the left and right sides of the longitudinal direction X of the absorbent body 5 is extended. Pair of wing portions 7, 7. Further, the side flap portion 6 also largely protrudes toward the outer side of the lateral direction Y at the rear portion C, whereby a pair of rear wing portions 8, 8 are extended on both sides of the main body 5 along the longitudinal direction X. Further, as shown in FIG. 1, the front sheet 2 and the back sheet 3 are respectively extended from the front end and the rear end of the longitudinal direction X of the absorber 4 toward the outer side of the longitudinal direction X, and in the extension portions, by the adhesive, A known sealing method such as heat sealing or ultrasonic sealing is joined to each other to form an end seal portion.

側翼部7係折回至短褲等穿著之衣服之褲襠部之非肌膚對向面(外表面)而使用者。如圖1所示，側翼部7於俯視時具有下底(較上底更長之邊)位於吸收性本體5之側部側之大致梯形形狀。於側翼部7之非肌膚對向面，形成有將該側翼部7(衛生棉1)固定於短褲等穿著之衣服(未圖示)的側翼部黏著部(未圖示)，藉由該側翼部黏著部，而於使用時，可將折回至穿著之衣服之褲襠部之非肌膚對向面(外面)側之側翼部7黏著固定於該褲襠部。再者，於衛生棉1中，吸收性本體5與側翼部7之交界線為將側翼部7之縱向X之兩根部連接之直線(未圖示)。The side flap portion 7 is folded back to the non-skin opposing surface (outer surface) of the crotch portion of the wearing clothes such as shorts. As shown in FIG. 1, the side flap portion 7 has a substantially trapezoidal shape in which the lower bottom (the longer side than the upper base) is located on the side of the side of the absorbent body 5 in plan view. A flanking portion adhesion portion (not shown) for fixing the side flap portion 7 (sanitary napkin 1) to a garment such as a pair of shorts (not shown) is formed on the non-skin opposing surface of the side flap portion 7, and the flap is formed by the flap The adhesive portion is adhered to the crotch portion of the non-skin opposing (outer) side of the crotch portion of the worn garment when it is used. Further, in the sanitary napkin 1, the boundary line between the absorbent main body 5 and the side flap portion 7 is a straight line (not shown) that connects the two ends of the longitudinal direction X of the side flap portion 7.

於一對後方翼部8、8各自之非肌膚對向面(側片材10之非肌膚對向面)，形成有將該後方翼部8(衛生棉1)固定於短褲等穿著之衣服(未圖示)的縱長之後方黏著部9。後方黏著部9於俯視時呈縱向X較長之矩形形狀。如圖1所示，一個後方翼部8中之後方黏著部9與另一個後方翼部8中之後方黏著部9係相同形狀相同尺寸且於縱向X上存在於相同位置，且以將吸收性本體5於橫向Y分成兩部分之中心線(未圖示)為基準而左右對稱地形成。後方翼部8係於將其固定於穿著之衣服時不折回，於其非肌膚對向面擴展之狀態(向吸收性本體5之側方延伸之狀態)下，經由後方黏著部9而黏著固定於穿著之衣服的肌膚對向面(內表面)。後方黏著部9及上述側翼部黏著部係藉由將熱熔黏著劑塗佈於特定部位而設置，於衛生棉1使用前藉由包括膜、不織布、紙等之未圖示之剝離片材而被覆。The non-skin opposing surface of each of the pair of rear wing portions 8 and 8 (the non-skin opposing surface of the side sheet 10) is formed with a garment for fastening the rear flap portion 8 (sanitary napkin 1) to a pair of shorts or the like ( The longitudinally long side adhesive portion 9 (not shown). The rear adhesive portion 9 has a rectangular shape in which the longitudinal direction X is long in plan view. As shown in FIG. 1, the rear side adhesive portion 9 of one rear wing portion 8 has the same shape and the same shape as the rear side adhesive portion 9 of the other rear wing portion 8, and exists in the same position in the longitudinal direction X, and is absorbent. The main body 5 is formed bilaterally symmetrically with respect to a center line (not shown) in which the lateral direction Y is divided into two parts. The rear wing portion 8 is not folded back when it is fixed to the clothes to be worn, and is adhered and fixed via the rear adhesive portion 9 in a state in which the non-skin opposing surface is expanded (a state extending toward the side of the absorbent body 5). On the opposite side (inner surface) of the skin of the dress. The rear adhesive portion 9 and the side flap portion are provided by applying a hot-melt adhesive to a specific portion, and the sanitary sheet 1 includes a release sheet (not shown) such as a film, a nonwoven fabric, or a paper before use. Covered.

如圖1~圖3所示，於吸收性本體5之肌膚對向面(正面片材2之肌膚對向面)，形成有正面片材2及吸收體4朝向背面片材3側而一體地凹陷而成之線狀槽，該線狀槽包含於後方部C沿著縱向X延伸之縱槽51、及於後方部C位於較縱槽51靠橫向Y之內側之內側槽61。縱槽51為位於較內側槽61靠橫向Y之外側之槽，故而亦稱為外側槽(外側縱槽)。此處，關於內側槽61，所謂「位於較縱槽靠橫向之內側」，係指於與橫向Y平行之同一之假想直線上內側槽61位於較縱槽51更靠內側的位置。線狀槽可藉由伴隨熱或不伴隨熱之壓縮加工、或者超音波壓紋等壓紋加工且按照常用方法形成。於線狀槽中，正面片材2及吸收體4藉由熱融黏等而一體化。As shown in FIG. 1 to FIG. 3, the skin facing surface (the skin facing surface of the front sheet 2) of the absorbent main body 5 is formed integrally with the front sheet 2 and the absorbent body 4 toward the back sheet 3 side. The linear groove formed by the recess includes a vertical groove 51 extending in the longitudinal direction X at the rear portion C, and an inner groove 61 located at the inner side of the longitudinal groove Y in the lateral direction Y at the rear portion C. The vertical groove 51 is a groove located on the outer side of the inner side groove 61 in the lateral direction Y, and is therefore also referred to as an outer groove (outer longitudinal groove). Here, the inner groove 61 is referred to as "the inner side in the lateral direction of the longitudinal groove", and the inner groove 61 on the imaginary straight line which is parallel to the lateral direction Y is located further inside than the vertical groove 51. The linear grooves can be formed by embossing with or without heat, or embossing such as ultrasonic embossing, and according to a usual method. In the linear groove, the front sheet 2 and the absorber 4 are integrated by heat fusion or the like.

若如此之線狀槽形成於衛生棉1之肌膚對向面，則可有效地抑制吸收體4之平面方向上的液體之擴散，又，可防止吸收體4之褶皺。線狀槽之形成對防止經血等排泄液之擴散、提高穿著時相對於身體之密接性等特別有效。尤其是，位於後方部C之縱槽51可有效地防止後方部C之褶皺及後斜方向之洩漏，內側槽61於穿著衛生棉1時沿著穿著者之臀部之槽，藉此可有效地防止後漏。線狀槽之寬度(與長度方向正交之方向之長度)及深度與此種吸收性物品中之線狀槽同樣地設定即可。When such a linear groove is formed on the skin facing surface of the sanitary napkin 1, the diffusion of the liquid in the planar direction of the absorbent body 4 can be effectively suppressed, and the wrinkles of the absorbent body 4 can be prevented. The formation of the linear groove is particularly effective for preventing the diffusion of excretory fluid such as menstrual blood and improving the adhesion to the body during wearing. In particular, the longitudinal groove 51 at the rear portion C can effectively prevent the wrinkles of the rear portion C and the leakage of the rear oblique direction, and the inner groove 61 can follow the groove of the wearer's buttocks when the sanitary napkin 1 is worn, thereby effectively Prevent leaks afterwards. The width of the linear groove (the length in the direction orthogonal to the longitudinal direction) and the depth may be set in the same manner as the linear groove in the absorbent article.

此處，所謂關於縱槽之「延伸」，並不限定於縱槽於中途不中斷而連續之狀態，亦可如下述中斷部52A、52B般，為比較短之長度(大概8mm以下)、不存在構成縱槽之凹陷部(壓紋部)的部分(非凹陷部)，只要縱槽整體上實質上於縱向連續即可。又，所謂線狀槽之「線狀」，並不限定於槽(凹陷部)之形狀於俯視時為直線，亦包含曲線，各線既可為連續線亦可為虛線。例如，線狀槽亦可由不連續之多數之壓紋(例如，點壓紋)所成之行而構成。於該情形時，鄰接之壓紋間之距離較中斷部之長度更短。Here, the "extension" of the vertical grooves is not limited to the state in which the vertical grooves are continuous without interruption in the middle, and may be a relatively short length (approximately 8 mm or less) or the like as in the following interruption portions 52A and 52B. There is a portion (non-recessed portion) constituting the depressed portion (embossed portion) of the vertical groove, and the longitudinal groove as a whole may be substantially continuous in the longitudinal direction. Further, the "linear shape" of the linear grooves is not limited to the shape of the grooves (recessed portions), and is a straight line in a plan view, and includes a curved line. Each of the lines may be a continuous line or a broken line. For example, the linear grooves may also be formed by a discontinuous majority of embossing (e.g., dot embossing). In this case, the distance between adjacent embossments is shorter than the length of the interruption.

如圖1所示，縱槽51係隔著將吸收性本體5於橫向Y分成兩部分之中心線(未圖示)而形成有一對，該等一對縱槽51、51以該中心線為基準而左右對稱地形成。一對縱槽51、51分別不僅延伸至後方部C，亦延伸至排泄部對向部B及前方部A，於排泄部對向部B中，將中高部42之橫向Y之外側沿著縱向X延伸。又，排泄部對向部B中，縱槽51成為朝向橫向Y之內側凸出之曲線狀，一對縱槽51、51間之間隔自排泄部對向部B之縱向X之前後端側朝向中央側而變窄。本實施形態之衛生棉1中，於排泄部對向部B配置有吸收體4之中高部42，藉由該構成之一對縱槽51、51，而使中高部42之縱向X之中央容易朝向穿著者肌膚側隆起。又，側片材10與吸收性本體5之第1接合線11、11成為於排泄部對向部B朝向橫向Y之外側凸出之曲線狀，故而，如圖1所示，排泄部對向部B之縱向X之中央區域中，槽51與第1接合線11之間隔較其前後區域變寬。因此，越過槽51之體液一面向縱向X之前後方向擴散一面導向由側片材10與正面片材2而劃分形成之空間部P(參照圖2)，故而可抑制向橫向側部之液流速度。而且，因第1接合線11成為朝向橫向Y之外側凸出之曲線狀，故而，排泄部對向部B之縱向X之中央區域與其前後區域相比空間部P之容量較大，因此容易抑制體液越過側片材10而向橫向側部洩漏之不良情況。As shown in Fig. 1, the vertical groove 51 is formed with a pair of center lines (not shown) that divide the absorbent body 5 into two portions in the lateral direction Y, and the pair of longitudinal grooves 51, 51 are centered on the center line. The reference is formed bilaterally symmetrically. The pair of longitudinal grooves 51 and 51 extend not only to the rear portion C but also to the drain portion facing portion B and the front portion A. In the drain portion facing portion B, the lateral direction Y of the middle portion 42 is along the longitudinal direction. X extension. Further, in the opposing portion B of the excretion portion, the vertical groove 51 has a curved shape that protrudes toward the inner side of the lateral direction Y, and the interval between the pair of longitudinal grooves 51 and 51 is directed from the front end side of the longitudinal direction X of the opposing portion B of the excretory portion. It narrows on the center side. In the sanitary napkin 1 of the present embodiment, the upper portion 42 of the absorbent body 4 is disposed in the opposing portion B of the excretory portion, and by the pair of the longitudinal grooves 51 and 51, the center of the longitudinal direction X of the intermediate portion 42 is made easy. It bulges toward the wearer's skin. Further, the first bonding wires 11 and 11 of the side sheet 10 and the absorbent main body 5 have a curved shape in which the excretory portion opposing portion B protrudes toward the outer side of the lateral direction Y. Therefore, as shown in Fig. 1, the excretory portion is opposed to each other. In the central region of the longitudinal direction X of the portion B, the interval between the groove 51 and the first bonding wire 11 is wider than the front and rear regions. Therefore, the body liquid that has passed through the groove 51 is diffused toward the longitudinal direction X and is guided toward the space portion P (see FIG. 2) formed by the side sheet 10 and the front sheet 2, so that the flow to the lateral side portion can be suppressed. speed. Further, since the first bonding wire 11 has a curved shape that protrudes toward the outer side of the lateral direction Y, the central portion of the longitudinal direction X of the opposing portion B of the excretory portion has a larger capacity than the front and rear regions of the space portion P, so that it is easy to suppress The problem that the body fluid leaks over the side sheet 10 and leaks to the lateral side.

於本實施形態中，作為上述線狀槽，如圖1所示，除了沿著縱向X延伸之槽51、61以外，沿著橫向Y延伸之橫槽71、72自吸收性本體5之縱向X之前側朝向後側按照該順序形成。橫槽71位於前方部A，俯視時朝向吸收性本體5之縱向X之前端凸狀地彎曲，又，橫槽72位於後方部C，俯視時朝向吸收性本體5之縱向X之後端凸狀地彎曲，兩槽71、72係僅其凸出之方向不同而俯視形狀相同。橫槽71、72各自之凸出之頂部位於吸收性本體5之橫向Y之中央。一對縱槽51、51與橫槽71、72於其等之長度方向之端部連接，藉此，於吸收性本體5之肌膚 對向面形成有俯視時呈環狀(大致長橢圓形狀)之槽。此處所謂「俯視」，係指如圖1般，自肌膚抵接面側平面狀地觀察衛生棉1。In the present embodiment, as the linear groove, as shown in Fig. 1, except for the grooves 51, 61 extending in the longitudinal direction X, the lateral grooves 71, 72 extending in the lateral direction Y are from the longitudinal direction X of the absorbent body 5. The front side is formed toward the rear side in this order. The lateral groove 71 is located at the front portion A, and is convexly curved toward the front end of the longitudinal direction X of the absorbent body 5 in plan view, and the lateral groove 72 is located at the rear portion C, and is convex toward the rear end of the longitudinal direction X of the absorbent body 5 in plan view. In the case of bending, the two grooves 71 and 72 are different in plan view shape only in the direction in which they protrude. The convex tops of the lateral grooves 71, 72 are located at the center of the lateral direction Y of the absorbent body 5. The pair of longitudinal grooves 51 and 51 are connected to the end portions of the lateral grooves 71 and 72 in the longitudinal direction thereof, thereby absorbing the skin of the absorbent body 5 The opposing surface is formed with a groove having a ring shape (a substantially elliptical shape) in plan view. Here, "looking up" means that the sanitary napkin 1 is viewed in a planar shape from the skin contact surface side as shown in FIG.

內側槽61如圖1所示，於俯視時，呈朝向吸收性本體5之縱向X之後端凸出之大致U字狀，其凸出之頂部成為縱向X之後端61b。U字狀之內側槽61之後端61b(U字之凸出之頂部)位於後方翼部8之縱向X之大致中央。又，U字狀之內側槽61之縱向X之前端61a、61a位於排泄部對向部B與後方部C之交界15或其附近(距交界15為5mm以內)，藉此，藉由內側槽61可有效地防止自排泄部對向部B漏出之經血等排泄液之平面方向上之擴散。排泄部對向部B與後方部C之交界15與「將一對側翼部7、7各自之縱向X之後方側之根部連接之直線」或「通過中高部42之縱向X之後端沿著橫向Y延伸之直線」一致，亦為後方翼部8之縱向前端8a存在之位置。於U字狀之內側槽61中沿著縱向延伸之部分(後端61b及其附近以外之部分)以於俯視時其縱向X之前端61a位於較後端靠橫向Y之外側之方式，相對於縱向X而傾斜。即，內側槽61於俯視時，為其前端61a側向較後端61b側更向橫向外側擴散且朝向前方部A側打開的U字狀，且為構成該U字之一對槽61、61之間隔(橫向寬度)隨著朝向後端部61b而較窄的形狀。藉此，可有效地同時實現相對於穿著者臀部之服貼性與排泄物之洩漏抑制。As shown in FIG. 1, the inner groove 61 has a substantially U-shape that protrudes toward the rear end of the longitudinal direction X of the absorbent body 5 in plan view, and the convex top portion becomes the longitudinal direction X rear end 61b. The U-shaped inner groove 61 rear end 61b (the top of the U-shaped projection) is located substantially at the center of the longitudinal direction X of the rear wing portion 8. Further, the longitudinal X front ends 61a and 61a of the U-shaped inner groove 61 are located at or near the boundary 15 between the opposing portion B and the rear portion C of the drain portion (within 5 mm from the boundary 15), whereby the inner groove 61 can effectively prevent the diffusion in the plane direction of the excretory fluid such as menstrual blood leaking from the opposing portion B of the excretory portion. The boundary between the opposing portion B and the rear portion C of the excretory portion and the "straight line connecting the root portion of the longitudinal side of each of the pair of side flap portions 7 and 7" or "the longitudinal end of the intermediate portion 42 through the longitudinal direction X" along the lateral direction The straight line of the Y extension is uniform, and is also the position where the longitudinal front end 8a of the rear wing portion 8 exists. a portion extending in the longitudinal direction of the U-shaped inner groove 61 (portion other than the rear end 61b and its vicinity) such that the longitudinal end X of the longitudinal direction X is located on the outer side of the lateral direction Y from the rear end in a plan view, with respect to Tilt in the longitudinal direction X. In other words, the inner groove 61 is formed in a U shape in which the front end 61a side is more outwardly spread toward the outer side than the rear end 61b side and is opened toward the front portion A side, and is formed as a pair of grooves 61 and 61. The interval (lateral width) is a narrower shape toward the rear end portion 61b. Thereby, it is possible to effectively achieve both the conformability of the wearer's buttocks and the leakage suppression of the excrement.

作為本實施形態之衛生棉1之主要特徵之一，可列舉如下方面：如圖1及圖3所示，縱槽51於縱向X中斷，其中斷部52A、52B存在於由2條假想直線L1、L2夾持之後方部特定區域CS內，且內側槽61存在於後方部特定區域CS內，該2條假想直線L1、L2係分別通過後方黏著部9之縱向X之前後端9a、9b且沿著橫向Y延伸。As one of the main features of the sanitary napkin 1 of the present embodiment, as shown in FIGS. 1 and 3, the vertical groove 51 is interrupted in the longitudinal direction X, and the interruption portions 52A and 52B are present in the two imaginary straight lines L1. The L2 is sandwiched in the square specific region CS, and the inner groove 61 is present in the rear specific region CS. The two imaginary straight lines L1 and L2 pass through the longitudinal X front end 9a, 9b of the rear adhesive portion 9, respectively. Extending along the lateral direction Y.

此處，所謂「縱槽(沿著縱向延伸之槽)於縱向中斷」，係指於沿著縱向X觀察縱槽時，存在無構成該縱槽之凹陷部(壓紋部)之部分(非凹陷部，非壓紋部)的狀態。即，使將縱槽於橫向Y橫切之1條假想直 線，維持使該假想直線之長度方向與橫向Y一致的狀態而遍及該縱槽之全長地於縱向X移動時，於存在該假想直線與構成該縱槽之凹陷部不重疊之部分之情形時，該縱槽於縱向X中斷，該不重疊之部分為「中斷部」。因此，例如，即便於較縱槽之「中斷部」更靠縱向X之前方側的位置，吸收性本體產生褶皺(變形)，且該褶皺經由該縱槽而傳遞至縱向X之後方側，該褶皺之傳遞亦會於「中斷部」中斷，不會傳遞至較「中斷部」靠縱向X之後方側。圖1及圖3中符號52A、52B所示之「中斷部」滿足該縱槽之中斷之條件。Here, the term "the longitudinal groove (the groove extending in the longitudinal direction) is interrupted in the longitudinal direction" means that when the longitudinal groove is observed along the longitudinal direction X, there is a portion where the depressed portion (embossed portion) constituting the longitudinal groove is present (non- The state of the depressed portion, the non-embossed portion). That is, an imaginary straight line that cuts the longitudinal groove in the lateral direction Y When the length of the imaginary straight line is aligned with the lateral direction Y and the movement is continued in the longitudinal direction X over the entire length of the vertical groove, the line is in a state where the imaginary straight line does not overlap with the depressed portion constituting the vertical groove. The vertical slot is interrupted in the longitudinal direction X, and the non-overlapping portion is the "interruption portion". Therefore, for example, even in a position closer to the front side than the longitudinal direction X of the "interrupted portion" of the vertical groove, the absorbent body is wrinkled (deformed), and the wrinkles are transmitted to the side after the longitudinal direction X through the longitudinal groove, which The transfer of the pleats will also be interrupted at the "interruption" and will not be transmitted to the side of the "interruption" in the longitudinal direction X. The "interrupt portion" shown by reference numerals 52A and 52B in Figs. 1 and 3 satisfies the condition of the interruption of the vertical groove.

相對於此，例如，就圖4所示之縱槽80而言，構成該縱槽80之2條連續直線狀之槽81、82不連接，於兩槽81、82間存在非凹陷部(非壓紋部)83，但於使將縱槽80於橫向Y橫切之1條假想直線L0維持使其長度方向與橫向Y一致之狀態而於縱向X移動之情形時，假想直線L0始終與包含存在非凹陷部83之部分在內的、構成縱槽80之凹陷部重疊，縱槽80於縱向中斷，非凹陷部83並非本創作中所言之「中斷部」。因此，假使於較非凹陷部83更靠縱向X之前方側(圖4之上方側)的位置、吸收性本體產生褶皺之情形時，該褶皺會經由非凹陷部83存在之部分，而傳遞至縱向X之後方側(圖4之下方側)。On the other hand, for example, in the vertical groove 80 shown in FIG. 4, the two straight linear grooves 81 and 82 constituting the vertical groove 80 are not connected, and there is a non-recessed portion between the two grooves 81 and 82. In the embossed portion 83, when the longitudinal line L0 in which the longitudinal groove 80 is transversely cut in the lateral direction Y is maintained in a state in which the longitudinal direction is aligned with the lateral direction Y and is moved in the longitudinal direction X, the imaginary straight line L0 is always included. The recessed portions constituting the vertical grooves 80 are overlapped in the non-recessed portion 83, and the longitudinal grooves 80 are interrupted in the longitudinal direction, and the non-recessed portions 83 are not the "interrupted portions" as referred to in the present creation. Therefore, if the position of the absorbent body is wrinkled more than the position of the non-recessed portion 83 in the longitudinal direction X (the upper side of FIG. 4), the wrinkles are transmitted to the portion where the non-recessed portion 83 exists, and are transmitted to The side of the longitudinal direction X (the lower side of Figure 4).

又，關於本創作之「後方部特定區域」，於本實施形態中，如圖1及圖3所示，一對後方翼部8、8中之一個後方黏著部9與另一個後方黏著部9以將吸收性本體5於橫向Y分成兩部分之中心線(未圖示)為基準而左右對稱地形成，故而，兩黏著部9、9彼此的、決定後方部特定區域CS之假想直線L1、L2一致，但當一個後方黏著部與另一個後方黏著部左右非對稱地形成之情形時，於其等左右非對稱之一對黏著部彼此的、通過縱向前後端隔著且沿著橫向延伸之2條假想直線不一致，通過一個後方黏著部之縱向前後端之2條假想直線與通過另一個後方黏著部之縱向前後端之2條假想直線之合計4條假想直線係不重疊 地分別獨立存在。於該情形時，將由通過左右任一個後方黏著部9之縱向前後端部各自且沿著橫向Y平行地延伸之2條假想直線夾持之區域設為「後方部特定區域」即可，較佳為，將由該等4條假想直線之中位於縱向內側之2條決定之區域(於縱向一個後方黏著部與另一個後方黏著部重疊之區域)設為「後方部特定區域」。Further, in the present embodiment, in the present embodiment, as shown in Figs. 1 and 3, one of the pair of rear wing portions 8 and 8 has a rear adhesive portion 9 and the other rear adhesive portion 9 as shown in Figs. 1 and 3 . The center line (not shown) in which the absorptive body 5 is divided into two portions in the lateral direction Y is formed bilaterally symmetrically. Therefore, the imaginary straight line L1 of the specific portions CS of the rear portions of the two adhesive portions 9 and 9 is determined. L2 is the same, but when one rear adhesive portion is formed asymmetrically with the other rear adhesive portion, one of the left and right asymmetrical portions of the adhesive portion is separated from each other by the longitudinal front and rear ends and extends in the lateral direction. The two imaginary straight lines do not overlap, and the two imaginary straight lines passing through the longitudinal front and rear ends of one rear adhesive portion and the two imaginary straight lines passing through the longitudinal front and rear ends of the other rear adhesive portion do not overlap. The grounds exist independently. In this case, it is preferable that the region sandwiched by the two imaginary straight lines extending in parallel with each other in the longitudinal direction of the left and right longitudinal end portions of the left and right rear adhesive portions 9 is a "rear portion specific region". The area determined by the two of the four imaginary straight lines on the inner side in the longitudinal direction (the area in which one rear adhesive portion overlaps the other rear adhesive portion in the longitudinal direction) is referred to as "the rear specific region".

如圖1及圖3所示，一對縱槽51、51分別具有複數個(2個)中斷部52A、52B，該複數個中斷部52A、52B全部存在於後方部特定區域CS內。又，複數個中斷部52A、52B之中僅位於縱向X之最前方之中斷部52A存在於內側槽61之側方，位於後方之中斷部52B不存在於內側槽61之側方。內側槽61不具有本創作中所言之「中斷部」，而為連續。內側槽61之後端61b(U字之凸出之頂部)位於縱槽51所具有之複數個上述中斷部中之位於後方部特定區域CS內之縱向X之最前方之中斷部52A與位於最後方之中斷部52B之間。As shown in FIGS. 1 and 3, each of the pair of vertical grooves 51 and 51 has a plurality of (two) interruption portions 52A and 52B, and all of the plurality of interruption portions 52A and 52B are present in the rear specific region CS. Further, among the plurality of interruption portions 52A and 52B, only the interruption portion 52A located at the forefront of the longitudinal direction X exists on the side of the inner groove 61, and the interruption portion 52B located at the rear side does not exist on the side of the inner groove 61. The inner groove 61 does not have the "interruption portion" as described in the present creation, but is continuous. The rear end 61b of the inner groove 61 (the top of the U-shaped projection) is located at the foremost end of the longitudinal direction X of the plurality of the interruption portions of the longitudinal groove 51 located in the rear specific region CS. Between the interruptions 52B.

於衛生棉1中，縱槽51於後方部C在縱向X上中斷，藉此，於穿著衛生棉1時，於排泄部對向部B產生之褶皺不會傳遞至較該中斷部52A(複數個中斷部中之位於縱向X之最前方之中斷部)更靠縱向X之後方，故而難以產生後方翼部8之褶皺或捲縮，並且，由位於中斷部52A之橫向Y之內側的吸收性本體5之橫向中央部、尤其是俯視時呈U字狀之內側槽61包圍之部分朝向穿著者之肌膚側適當地隆起，結果，後方部C追隨穿著者之各種活動或姿勢之變化而服貼於身體。若該中斷部52A之橫向Y之內側之隆起過大，則有導致中斷部52A之橫向Y之外側(後方翼部8)之褶皺或捲縮之虞，但於衛生棉1中，中斷部52A存在於由一對後方黏著部9、9夾持之區域即後方部特定區域CS內，故而該隆起被適當地抑制為後方翼部8不會產生褶皺或捲縮之程度。又，中斷部52B存在於較內側槽61更靠縱向X之後方的位置，藉此，較內側槽61更靠後方側的位置不會產生由內側槽61所引起之適當之隆 起，於吸收性本體5維持大致平面狀態之狀態下，中斷部52B成為起點而變得容易沿著身體，故而後方部C之身體追隨性提高。因此，衛生棉1之後方部C(後方翼部8)難以產生褶皺或捲縮，具有可追隨穿著者之各種活動或姿勢之變化之高身體追隨性。In the sanitary napkin 1, the longitudinal groove 51 is interrupted in the longitudinal direction X at the rear portion C, whereby when the sanitary napkin 1 is worn, wrinkles generated in the opposing portion B of the excretory portion are not transmitted to the interruption portion 52A (plurality The interruption portion of the interruption portion located at the forefront of the longitudinal direction X is further behind the longitudinal direction X, so that it is difficult to generate wrinkles or curls of the rear wing portion 8, and the absorption is located inside the lateral direction Y of the interruption portion 52A. The central portion of the main body 5, which is surrounded by the U-shaped inner groove 61 in a plan view, is appropriately raised toward the skin side of the wearer. As a result, the rear portion C follows the changes in the various activities or postures of the wearer. In the body. If the ridge of the inner side of the lateral direction Y of the interruption portion 52A is excessively large, the outer side (the rear wing portion 8) of the interruption portion 52A may be wrinkled or curled. However, in the sanitary napkin 1, the interruption portion 52A exists. In the region of the rear portion specific region CS which is sandwiched by the pair of rear adhesive portions 9, 9, the ridge is appropriately suppressed so that the rear wing portion 8 does not wrinkle or curl. Further, the interruption portion 52B exists at a position further behind the inner side groove 61 in the longitudinal direction X, whereby the position on the rear side of the inner groove 61 does not cause an appropriate bulging caused by the inner groove 61. In the state in which the absorptive main body 5 maintains a substantially planar state, the interruption portion 52B becomes a starting point and becomes easy to follow the body, so that the body followability of the rear portion C is improved. Therefore, the rear side portion C (the rear wing portion 8) of the sanitary napkin 1 is less likely to wrinkle or curl, and has high body followability which can follow changes in various activities or postures of the wearer.

若要體現上述作用效果(難以產生後方部之褶皺或捲縮，身體追隨性優異)，則需要「縱槽51於縱向X中斷，其中斷部存在於後方部特定區域CS內，且內側槽61存在於後方部特定區域CS內」之構成(基本構成)，不需要具備本實施形態之衛生棉1之其他構成，例如下述構成1及2。因此，於本創作中，只要縱槽51所具有之複數個中斷部之任一個存在於後方部特定區域CS內即可，又，於後方部特定區域CS內，內側槽亦可不存在於中斷部之側方。但，除了具備上述基本構成以外進而具備下述構成1及構成2之至少1個，藉此，可進一步確實地體現上述作用效果。In order to exhibit the above-described effects (it is difficult to produce wrinkles or curls in the rear portion, and excellent body followability), it is necessary that "the longitudinal groove 51 is interrupted in the longitudinal direction X, and the interruption portion exists in the specific portion CS in the rear portion, and the inner groove 61 is provided. The configuration (basic configuration) of the present invention in the rear specific region CS does not require the other configuration of the sanitary napkin 1 of the present embodiment, and for example, the following configurations 1 and 2. Therefore, in the present creation, any one of the plurality of interruption portions of the vertical groove 51 may exist in the rear specific region CS, and the inner groove may not exist in the interruption portion in the rear specific region CS. Side of the side. However, in addition to the above-described basic configuration, at least one of the following configurations 1 and 2 is provided, whereby the above-described operational effects can be further reliably obtained.

．構成1：縱槽51所具有之複數個(2個)中斷部52A、52B之中、位於縱向X之最前方之最前方中斷部52A存在於後方部特定區域CS內(縱槽51所具有之複數個中斷部52A、52B全部存在於後方部特定區域CS內)。. In the configuration 1, the foremost interruption portion 52A located at the forefront of the longitudinal direction X among the plurality of (two) interruption portions 52A and 52B of the vertical groove 51 is present in the rear portion specific region CS (the vertical groove 51 has All of the plurality of interruption units 52A and 52B are present in the rear specific region CS).

．構成2：於後方部特定區域CS內，內側槽61存在於縱槽51之中斷部(尤其最前方中斷部52A)之側方(橫向Y之外側)。. Configuration 2: In the rear specific region CS, the inner groove 61 is present on the side of the interruption portion (particularly the frontmost interruption portion 52A) of the vertical groove 51 (outside of the lateral direction Y).

自進一步確實地體現上述作用效果之觀點考慮，後方黏著部9之縱向X上之長度T1(參照圖1)相對於後方翼部8之縱向X之長度T2(參照圖1)而言較佳為10%以上，更佳為15%以上，而且，較佳為30%以下，更佳為25%以下，更具體而言，較佳為10~30%，更佳為15~25%。又，後方黏著部9之長度T1較佳為15mm以上，更佳為20mm以上，而且，較佳為50mm以下，更佳為45mm以下，更具體而言，較佳為15~50mm，更佳為20~45mm。再者，後方黏著部9亦可由排列 於縱向X之複數個黏著要素而構成。該情形時之縱向X之長度為存在於最前側之黏著要素之前側端部至存在於最後側之黏著要素之後側端部為止之距離。From the viewpoint of further realizing the above-described effects, the length T1 (refer to FIG. 1) in the longitudinal direction X of the rear adhesive portion 9 is preferably the length T2 (refer to FIG. 1) of the longitudinal direction X of the rear wing portion 8 (see FIG. 1). More than 10%, more preferably 15% or more, and further preferably 30% or less, more preferably 25% or less, and more specifically, preferably 10 to 30%, more preferably 15 to 25%. Further, the length T1 of the rear adhesive portion 9 is preferably 15 mm or more, more preferably 20 mm or more, and is preferably 50 mm or less, more preferably 45 mm or less, and more specifically, preferably 15 to 50 mm, more preferably 20~45mm. Furthermore, the rear adhesive portion 9 can also be arranged It is composed of a plurality of adhesive elements in the longitudinal direction X. In this case, the length of the longitudinal direction X is the distance from the front end portion of the adhesive element on the foremost side to the rear end portion of the adhesive element existing on the last side.

自相同之觀點考慮，自排泄部對向部B與後方部C之交界15(後方翼部8之縱向前端8a)至後方黏著部9之縱向前端9a為止之長度T3(參照圖1)較佳為60mm以上，更佳為65mm以上，而且，較佳為90mm以下，更佳為80mm以下，更具體而言，較佳為60~90mm，更佳為65~80mm。From the same viewpoint, the length T3 (refer to FIG. 1) from the boundary 15 between the opposing portion B and the rear portion C of the excretory portion (the longitudinal front end 8a of the rear wing portion 8) to the longitudinal front end 9a of the rear adhesive portion 9 is preferable. It is 60 mm or more, more preferably 65 mm or more, and further preferably 90 mm or less, more preferably 80 mm or less, and more specifically, preferably 60 to 90 mm, more preferably 65 to 80 mm.

自相同之觀點考慮，中斷部52A、52B各自之縱向X之長度較佳為3mm以上，更佳為3.5mm以上，而且，較佳為8mm以下，更佳為7mm以下，更具體而言，較佳為3~8mm，更佳為3.5~7mm。From the same viewpoint, the length of each of the interruption portions 52A and 52B in the longitudinal direction X is preferably 3 mm or more, more preferably 3.5 mm or more, and further preferably 8 mm or less, more preferably 7 mm or less, and more specifically, more specifically Good for 3~8mm, better for 3.5~7mm.

再者，若縱槽51具有中斷部52A、52B，則可能會根據中斷部52A、52B之縱向X之長度之程度，而使存在於縱槽51之橫向Y之內側之經血等排泄液通過中斷部52A、52B向橫向Y之外側移行，從而誘發側漏。然而，於本實施形態中，如上所述，於中斷部52A、52B之橫向Y之外側，形成有由側片材10與正面片材2而劃分形成之空間部P(參照圖2)，故而即便排泄液通過中斷部52A、52B向橫向Y之外側移行，該排泄液亦會被收納於空間部P，因此難以移行至較第2接合線12靠橫向Y之外側，從而難以產生側漏。Further, when the vertical grooves 51 have the interruption portions 52A and 52B, the menstrual blood excretions existing inside the lateral direction Y of the longitudinal grooves 51 may be interrupted by the length of the longitudinal direction X of the interruption portions 52A and 52B. The portions 52A, 52B move toward the outer side of the lateral direction Y to induce side leakage. However, in the present embodiment, as described above, the space portion P (see FIG. 2) defined by the side sheet 10 and the front sheet 2 is formed on the outer side of the lateral direction Y of the interruption portions 52A and 52B. Even if the excretion liquid moves toward the outer side of the lateral direction Y by the interruption portions 52A and 52B, the excretion liquid is stored in the space portion P. Therefore, it is difficult to move to the outer side of the lateral direction Y of the second bonding wire 12, and it is difficult to cause side leakage.

如圖3所示，一對縱槽51、51係分別於後方部特定區域CS內具有由鄰接於縱向X之2個中斷部52A、52B夾持之分斷區域53。各分斷區域53係以於俯視時其縱向前端53a位於較縱向後端53b靠橫向Y之內側之方式，相對於縱向X而傾斜，一對分斷區域53、53之間隔隨著朝向縱向X之前方而逐漸變短。即，後方部特定區域CS內之一對分斷區域53、53於俯視時呈字(八字)狀，藉此，分斷區域53可更穩定性地維持面形狀且沿著穿著者之身體，從而可進一步謀求身體追隨性之提 高。As shown in FIG. 3, the pair of vertical grooves 51 and 51 respectively have a breaking region 53 sandwiched by two interrupting portions 52A and 52B adjacent to the longitudinal direction X in the rear specific region CS. Each of the breaking regions 53 is inclined with respect to the longitudinal direction X such that the longitudinal front end 53a thereof is located inside the lateral direction Y of the longitudinal rear end 53b in plan view, and the interval between the pair of breaking regions 53 and 53 is toward the longitudinal direction X. It gradually became shorter in the past. That is, one of the pair of divided regions 53, 53 in the rear specific region CS is in a plan view In the shape of a word (eight characters), the breaking region 53 can maintain the surface shape more stably and along the body of the wearer, thereby further improving the body followability.

As the front sheet 2, for example, a liquid-permeable sheet such as various nonwoven fabrics or perforated films subjected to hydrophilization treatment can be used. Further, as the back sheet 3, a material which is liquid impermeable or a material which is water-repellent can be used. As a material which is impervious to liquid, a resin film, a resin film having micropores and moisture permeability, a laminate such as a resin film and a non-woven fabric, or the like can be used, and as a water-repellent material, it can be used to include spunbonding and melting. Composite non-woven fabric, spunbonded non-woven fabric, hot-adhesive non-woven fabric, hot air non-woven fabric, etc., which are multi-layered structures such as spray and spunbond.

作為吸收體4，自衛生棉1之薄型化、低剛性化之觀點考慮，較理想的是並非使用將木材紙漿等之纖維材料進行纖維堆積而成之纖維堆積體，而使用與該纖維堆積體相比厚度較薄且低剛性之吸收性片材。於本實施形態之衛生棉1中，作為吸收性片材401~403，可較佳地使用經由處於濕潤狀態之吸水性聚合物所產生之黏著力、或另外添加之接著劑或接著性纖維等之黏合劑，使構成纖維間或構成纖維與吸水性聚合物之間結合，從而形成片材狀者等。又，作為吸收性片材，可使用利用日本專利特開平8-246395號公報記載之方法製造之吸收性片材；使隨著氣流而供給之粉碎紙漿及吸水性聚合物堆積之後，利用接著劑(例如乙酸乙烯酯系之接著劑，PVA(Polyvinyl Alcohol，聚乙烯醇)等)固定之乾式片材；於紙或不織布之間塗佈熱熔接著劑等之後，散佈高吸收性聚合物而獲得之吸收性片材；於紡黏或熔噴不織布製造步驟中調配高吸收性聚合物而獲得之吸收性片材等。作為吸收性片材作為較佳者，可列舉使吸水性聚合物固定於紙漿纖維之集合體而成者；使粒子狀之吸水性聚合物散佈於利用氣流成網法製造之乾式紙漿片材、2片不織布間而成者。該等吸收性片材可將一片裁斷為特定形狀而作為片材狀吸收體使用。作為吸收性片材之每1片之厚度，較佳 為0.1mm以上，尤佳為0.3mm以上，又，較佳為2mm以下，尤佳為1.5mm以下。更具體而言，較佳為0.1mm以上2mm以下，尤佳為0.3mm以上1.5mm以下。In view of the reduction in thickness and the low rigidity of the sanitary napkin 1, it is preferable to use a fiber deposit which is obtained by depositing a fiber material such as wood pulp, and to use the fiber deposit. Compared to thinner and less rigid absorbent sheets.
