Description

吸收性物品 Absorbent article

本發明係關於一種經期衛生棉等吸收性物品。 The present invention relates to an absorbent article such as menstrual napkin.

於經期衛生棉等吸收性物品中，已知有如下技術，即，以提高物品向穿著者之身體之服貼性，或將所排泄之液體向特定之方向誘導為目的，而形成將正面片材與吸收體一體地壓擠而成之壓擠條槽。若自正面片材側一體地壓擠該正面片材與吸收體，則因作為平坦之素材之正面片材被不均勻地拉伸而導致容易於壓擠條槽之附近出現皺紋。 以防止該皺紋之產生為目的，例如專利文獻1中提出有於形成自正面片材陷入至吸收體內之壓紋凹部時，於該壓紋凹部之底部之附近形成狹縫或衝壓孔，使壓紋凹部之與延伸方向正交之方向之伸縮性高於其他部分。 In absorbent articles such as menstrual sanitary napkins, there is known a technique of forming a front sheet for the purpose of improving the conformability of the article to the wearer's body or inducing the discharged liquid to a specific direction. The extruded strip is extruded integrally with the absorbent body. When the front sheet and the absorbent body are integrally pressed from the side of the front sheet, the front sheet which is a flat material is unevenly stretched, and wrinkles are likely to occur in the vicinity of the pressed strip groove. For the purpose of preventing the generation of the wrinkles, for example, in Patent Document 1, it is proposed to form a slit or a punched hole in the vicinity of the bottom of the embossed concave portion when forming the embossed concave portion from the front sheet into the absorbent body. The direction in which the groove concave portion is orthogonal to the extending direction is higher than that of the other portions.

由壓擠條槽之形成所引起之正面片材之皺紋之產生，於該正面片材具有凹凸構造之情形時變得更顯著。例如，專利文獻2及3中記載有如下之吸收性物品，該吸收性物品將於肌膚對向面側形成有線狀之複數條凹部及位於相鄰之該凹部間之凸部之正面片材、與吸收體一體地壓擠而形成壓擠條槽。於該等文獻中記載之吸收性物品中，除因壓擠條槽之形成而導致容易產生皺紋以外，亦因於正面片材形成凹部而導致容易產生皺紋。其原因在於，於吸收性物品之穿著狀態下，凹部作為變形之可撓軸而發揮作用，從而容易產生較深之皺紋。 The generation of wrinkles of the front sheet caused by the formation of the extruded strip grooves becomes more remarkable when the front sheet has a concave-convex structure. For example, Patent Literatures 2 and 3 disclose an absorbent article in which a plurality of linear concave portions and a front surface of a convex portion located between the adjacent concave portions are formed on the opposite side of the skin. The extruded body is pressed integrally with the absorbent body to form a squeeze groove. In the absorbent article described in these documents, wrinkles are easily formed in addition to the formation of the squeeze groove, and wrinkles are likely to occur due to the formation of the concave portion on the front sheet. The reason for this is that in the wearing state of the absorbent article, the concave portion functions as a flexible axis of deformation, and it is easy to generate deep wrinkles.

以下，參照圖式對本發明之吸收性物品，基於作為其較佳之一實施形態之經期衛生棉進行說明。如圖1及圖2所示，本實施形態之衛生棉1具備吸收性本體5，且具有相當於穿著者之前後方向之縱方向X及與其正交之橫方向Y，該吸收性本體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 an embodiment of the preferred embodiment with reference to the drawings. As shown in FIG. 1 and FIG. 2, the sanitary napkin 1 of the present embodiment includes an absorbent main 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 main body 5 is provided. The liquid-retaining 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構件(例如吸收性本體5)之於穿著吸收性物品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構件之於穿著吸收性物品時朝向與肌膚側為相反側(穿衣側)之面。又，縱方向X係與沿吸收性物品(吸收性本體)之長邊之方向(長度方向)一致，橫方向Y係與吸收性物品(吸收性本體)之寬度方向(與長度方向正交之方向)一致。 Furthermore, in the present specification, the skin facing absorbent article or its constituent members (for example, the absorbent main body 5) are applied to the skin side of the wearer when the absorbent article is worn, and the non-skin opposing surface is absorbed. The article or its constituent member faces the side opposite to the skin side (dressing side) when the absorbent article is worn. Further, the longitudinal direction X corresponds to the direction (longitudinal direction) along the long side of the absorbent article (absorbent body), and the transverse direction Y is the width direction of the absorbent article (absorbent body) (orthogonal to the longitudinal direction) The direction is the same.

吸收性本體5於縱方向X上具有：排泄部對向部B，其於穿著時與穿著者之排泄部對向配置；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)；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)。此處所提及之「穿著時」意 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，不包含衛生棉1處於自該穿著位置偏離之狀態之情形。 The absorbent body 5 has a drain portion facing portion B that faces the excretion portion of the wearer when worn in the longitudinal direction X, and a front portion A that is disposed at the opposite portion B of the excretory portion when worn. The ventral side (front side) of the wearer and the rear portion C are disposed on the back side (rear side) of the wearer facing portion B at the time of wearing. The term "when worn" as mentioned here It refers to a state in which the usual proper wearing position (the correct wearing position of the absorbent article) is maintained, and the sanitary napkin 1 is not in a state of being deviated from the wearing position.

衛生棉1除包含吸收性本體5以外，進而包含：一對側翼部7、7，其等分別自吸收性本體5之排泄部對向部B之沿縱方向X之兩側部向橫方向Y之外側延伸；及一對後方副翼部8、8，其等分別自吸收性本體5之後方部C之沿縱方向X之兩側部向橫方向Y之外側延伸。此種具有後方副翼部8之經期衛生棉適於在自寢時等長時間地使用，作為夜用經期衛生棉而尤其有用。 The sanitary napkin 1 further includes a pair of side flap portions 7 and 7 in addition to the absorbent body 5, and the like, respectively, from the side portions of the opposing portion B of the absorbent body 5 in the longitudinal direction X to the lateral direction Y. The outer side extends; and the pair of rear aileron portions 8, 8 extend from the outer side of the longitudinal direction X of the rear side portion C of the absorbent body 5 to the outer side of the lateral direction Y. Such a menstrual sanitary napkin having a rear aileron portion 8 is suitable for use for a long period of time from bed, and is particularly useful as a nighttime sanitary napkin.

再者，於本發明之吸收性物品中，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，通常係於吸收性物品之縱方向(吸收性物品之長度方向，圖中之X方向)具有側翼部之區域(夾於側翼部之縱方向一側之根部與另一側之根部之區域)。不具有側翼部之吸收性物品之排泄部對向部係與如下區域相同或較該區域窄之區域，該區域係將吸收性物品摺疊為3折之單個包裝形態時產生之於橫方向(吸收性物品之寬度方向，圖中之Y方向)橫穿該吸收性物品之兩條折彎線(未圖示)中、自該吸收性物品之縱方向之前端數起第1折彎線與第2折彎線所包圍之區域。 Further, in the absorbent article of the present invention, when the excretory portion facing portion has the side flap portion as in the sanitary napkin 1 of the present embodiment, it is usually in the longitudinal direction of the absorbent article (the longitudinal direction of the absorbent article) (X direction in the figure) A region having a side wing portion (a region sandwiched between a root portion on one side in the longitudinal direction of the side wing portion and a root portion on the other side). The excretory portion of the absorbent article having no side flap portion is the same as or narrower than the region in which the absorbent article is folded into a three-fold single package form in the lateral direction (absorption) The width direction of the article, the Y direction in the figure) traverses the two bend lines (not shown) of the absorbent article, and the first bend line and the number from the front end of the absorbent article in the longitudinal direction The area enclosed by 2 bend lines.

如圖2所示，正面片材2被覆吸收體4之肌膚對向面之整個區域，進而自吸收體4之沿縱方向X之兩側緣向橫方向Y之外側延伸。另一方面，背面片材3被覆吸收體4之非肌膚對向面之整個區域，進而自吸收體4之沿縱方向X之兩側緣向橫方向Y之外側延伸，而與下述之側片材10一同形成側副翼部6。背面片材3與側片材10於自吸收體4之沿縱方向X之兩側緣之延伸部藉由接著劑、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各者與吸收體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 area of the skin facing surface of the absorbent body 4, and further extends from the both side edges of the absorbent body 4 in the longitudinal direction X toward the outside of the lateral direction Y. On the other hand, the back sheet 3 covers the entire area of the non-skin opposing surface of the absorber 4, and further extends from the both sides of the longitudinal direction X of the absorber 4 to the outside of the lateral direction Y, and the side to the side below The sheet 10 forms the side ailerons 6 together. The back sheet 3 and the side sheet 10 are joined to each other at the extending portions of the side edges of the self-absorbent body 4 in the longitudinal direction X by a known joining method such as an adhesive, heat sealing, or ultrasonic sealing. Each of 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包含吸收性片材401~403 之積層體，如圖1及圖2所示，於排泄部對向部B具有多層部42。如圖2所示，多層部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多之部分。本實施形態中之多層部42之厚度較位於其周圍之部分厚，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包含：主吸收體40，其形成吸收體4之外形；及輔助吸收體41，其重疊配置於主吸收體40之一部分，且較主吸收體40小型。主吸收體40包含於俯視下為角度帶有弧度之大致矩形形狀且自前方部A經由排泄部對向部B而遍及至後方部C延伸之兩片相同形狀且相同大小之吸收性片材401、402，且輔助吸收體41於俯視下為大致矩形形狀，且自排泄部對向部B遍及至其附近之後方部C而配置。再者，亦可代替使用兩片吸收性片材401、402構成主吸收體40，而將一片吸收性片材摺疊為兩層來構成主吸收體40。輔助吸收體41係將1片吸收性片材403摺疊而形成為兩層構造者，配置於構成主吸收體40之兩片吸收性片材401、402之間。藉由於主吸收體40之一部分配置輔助吸收體41，可容易且有效率地使吸收體4之一部分之吸收容量增大。輔助吸收體41可代替配置於構成主吸收體40之兩片吸收性片材401、402間，而積層於構成主吸收體40之上側吸收性片材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，吸收性片材間亦可不接合，亦可藉由零星地散佈之接著劑等而接著。 As shown in Fig. 2, the absorbent body 4 of the present embodiment comprises absorbent sheets 401 to 403. As shown in FIGS. 1 and 2, the laminated body has a multilayer portion 42 in the opposing portion B of the excretory portion. As shown in Fig. 2, the multilayer portion 42 is a portion in which the number of laminated sheets constituting the absorbent sheet 4 is larger than the portion around the absorbent sheet. In the present embodiment, the thickness of the multi-layered portion 42 is thicker than the portion around the portion, and the slanting portion B is formed with a bulging portion that protrudes toward the front sheet 2 side (the skin facing surface side of the tampon 1). Further, the absorber 4 includes a main absorber 40 which is formed into an outer shape of 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 absorber 40 includes two sheets of the same shape and the same size of the absorbent sheet 401 extending from the front portion A through the drain portion facing portion B to the rear portion C in a substantially rectangular shape having an arc angle in a plan view. And 402, and the auxiliary absorber 41 is a substantially rectangular shape in plan view, and is disposed from the drain portion 44 to the vicinity of the portion C in the vicinity thereof. Further, instead of using the two sheets of absorbent sheets 401 and 402, the main absorbent body 40 may be formed, and one sheet of the absorbent sheet may be folded into two layers to constitute the main absorbent body 40. The auxiliary absorbent body 41 is formed by folding one sheet of the absorbent sheet 403 into a two-layer structure, and is disposed between the two sheets of absorbent sheets 401 and 402 constituting the main absorbent body 40. By arranging the auxiliary absorber 41 in one part of the main absorber 40, the absorption capacity of a part of the absorber 4 can be easily and efficiently increased. The auxiliary absorber 41 may be disposed between the two sheets of absorbent sheets 401 and 402 constituting the main absorbent body 40, and may be laminated on the opposite side of the skin constituting the upper absorbent sheet 401 of the main absorbent body 40, or may be laminated.

正面片材2與第二片材較佳為局部性地固定。藉此，抑制正面片材2之鼓起，提高正面片材2與第二片材之密接性，且使液體容易移行。因同樣之理由而較佳為第二片材與吸收體4之間亦局部性地固定。所謂局部性地固定係指具有包含點或線之固定部，該固定部分佈於整個片材面，雖無需均勻地分佈，但並非將固定之片材間整個面地固定。該固定部之面積較佳為被固定片材總面積之10%以上且60%以下左右。具體而言，間歇地塗佈接著劑，或間歇地實施熱密封而將正面片材2與第二片材局部性地固定。於間歇地塗佈接著劑之情形時，使用公知之方法，例如使用狹縫式塗佈槍間歇地塗佈接著劑，或使用螺旋噴槍呈螺旋狀地塗佈接著劑，或使用噴槍間歇地呈霧狀地塗佈接著劑，或使用點式塗佈槍呈點狀地塗佈接著劑而以正面片材2與第二片材之間維持體液之透過性之狀態將正面片材2與第二片材局部性地接著。作為塗佈之接著劑，例如較佳地使用熱熔接著劑。 The front sheet 2 and the second sheet are preferably partially fixed. Thereby, the bulging of the front sheet 2 is suppressed, the adhesion of the front sheet 2 and the second sheet is improved, and the liquid is easily moved. For the same reason, it is preferred that the second sheet and the absorbent body 4 are also locally fixed. By local fixation is meant a fixed portion having dots or lines that are disposed over the entire sheet surface and that do not need to be evenly distributed, but do not secure the entire surface between the fixed sheets. The area of the fixing portion is preferably about 10% or more and 60% or less of the total area of the fixed sheet. Specifically, the adhesive is applied intermittently, or heat sealing is intermittently performed to locally fix the front sheet 2 and the second sheet.

如圖1及2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側一體地凹陷而成之線狀槽，該線狀槽包含：縱槽51，其於後方部C沿縱方向X延伸；及內側槽61，其於後方部C位於較縱槽51更靠橫方向Y之內側。由於縱槽51為位於較內側槽61更靠橫方向Y之外側之槽，故而亦可稱為外側槽(外側縱槽)。線狀槽可藉由伴隨熱或不伴隨熱之壓紋、或超音波壓紋等壓紋加工而按照常規方法形成。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 FIGS. 1 and 2, the front surface 2 and the absorbent body 4 are integrally recessed toward the back sheet 3 on the skin facing surface of the absorbent body 5 (the skin facing surface of the front sheet 2). The linear groove 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. Since the vertical groove 51 is a groove located on the outer side of the inner groove 61 in the lateral direction Y, it may be referred to as an outer groove (outer longitudinal groove). The linear grooves can be formed by a conventional method by embossing with heat or embossing without heat, or ultrasonic embossing. In the linear groove, the front sheet 2 and the absorber 4 are integrated by heat fusion or the like.

若此種線狀槽形成於衛生棉1之肌膚對向面，則有效地抑制吸收體4之平面方向之液體之擴散，又，可防止吸收體4之褶皺。線狀槽之形成對於防止經血等排泄液之擴散、及於穿著時提昇對身體之密接性等尤其有效。尤其是，通過後方部C之縱槽51有效地防止後方部C之褶皺及後斜方向之漏出，內側槽61藉由於穿著衛生棉1時沿著穿著者之臀部之槽，而可有效地防止後漏。線狀槽之寬度(與長度方向正交之方向之長度)及深度只要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 is 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 spread of excretion fluid such as menstrual blood and for improving the adhesion to the body during wearing. In particular, the longitudinal groove 51 of the rear portion C effectively prevents the wrinkles of the rear portion C and the leakage of the rear oblique direction, and the inner groove 61 can be effectively prevented by the groove of the wearer's buttocks when the sanitary napkin 1 is worn. After leaking. 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.

The lateral groove 71 is located at the front portion A, and is curved convexly toward the front end in 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 faces the longitudinal direction of the absorbent body 5 in plan view. The rear end of the X is curved in a convex shape, and the two grooves 71 and 72 have the same convex shape and the same shape in plan view. The convex top of each of the lateral grooves 71, 72 is located at the center of the lateral direction Y of the absorbent body 5. The pair of vertical grooves 51 and 51 are connected to the end portions of the lateral grooves 71 and 72 in the longitudinal direction thereof, whereby a groove having a plan view (a substantially elliptical shape) is formed on the skin facing surface of the absorbent body 5 . .

內側槽61於如圖1所示之俯視下，形成朝向吸收性本體5之縱方向X之後端凸出之大致U字狀，該凸出之頂部成為縱方向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)位於後方副翼部8之縱方向X之大致中央。又，U字狀之內側槽61之縱方向X之前端61a、61a位於排泄部對向部B與後方部C之分界15或其附近，藉此，藉由內側槽61而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之擴散。排泄部對向部B與後方部C之分界15，與「連結一對側翼部7、7各者之縱方向X之後方側之根部之直線」、或「通過多層部42之縱方向X之後端而沿橫方向Y延伸之直線」一致，且亦為後方副翼部8之縱方向前端8a所處之位置。於U字狀之內側槽61中沿縱方向延伸之部分(後端61b及其附近以外之部分)，以於俯視下其縱方向X之前端61a位於較後端更靠橫方向Y之外側之方式，相對於縱方向X傾斜。 The inner groove 61 has a substantially U-shape which is convex toward the rear end of the longitudinal direction X of the absorbent body 5 in a plan view as shown in FIG. 1, and the top of the projection is a 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 rear aileron portion 8 in the longitudinal direction X. Further, the front end 61a, 61a of the U-shaped inner groove 61 in the longitudinal direction X is located at or near the boundary 15 between the opposing portion B of the drain portion and the rear portion C, whereby the inner groove 61 is effectively prevented from self-discharging.

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 pair of side flap portions 7 and 7 in the longitudinal direction X" or "through the longitudinal direction X of the multilayer portion 42" The straight line extending in the lateral direction Y at the end is uniform, and is also the position at which the longitudinal front end 8a of the rear aileron portion 8 is located. A portion extending in the longitudinal direction of the U-shaped inner groove 61 (a portion other than the rear end 61b and its vicinity) is located at the outer side of the longitudinal direction X in the longitudinal direction X in the plan view, and is located on the outer side of the lateral direction Y. The mode is inclined with respect to the longitudinal direction X.

於圖3中，將正面片材2之肌膚對向面之主要部分放大而表示。於正面片材2之肌膚對向面2a(衛生棉1之肌膚對向面)，沿分別與縱方向X及橫方向Y交叉之方向(即傾斜方向)延伸之凹陷部20形成為斜格子狀，藉由凹陷部20將正面片材2劃分為多個區域，而形成有多個劃分區域22。於圖3所示之實施形態中，凹陷部20遍及正面片材20之整個 區域而形成。亦可代替此，而至少於排泄部對向部B形成凹陷部20。再者，圖3中之X方向係與正交於正面片材製造時之片材之流動方向之方向(CD)相同之方向，且為亦與衛生棉1之縱方向X(參照圖1)相同之方向。又，圖3中之Y方向係與正面片材製造時之片材之流動方向(MD)相同之方向，且為亦與衛生棉1之橫方向Y(參照圖1)相同之方向。 In Fig. 3, the main part of the skin facing surface of the front sheet 2 is enlarged and shown. The concave portion 20 extending in the direction intersecting the longitudinal direction X and the lateral direction Y (that is, the oblique direction) on the skin facing surface 2a of the front sheet 2 (the skin facing surface of the sanitary napkin 1) is formed in a diagonal lattice shape. The front sheet 2 is divided into a plurality of regions by the depressed portion 20, and a plurality of divided regions 22 are formed. In the embodiment shown in FIG. 3, the recess 20 extends over the entire front sheet 20. Formed by the area. Instead of this, the recessed portion 20 may be formed at least at the opposing portion B of the drain portion. Further, the X direction in FIG. 3 is the same direction as the direction (CD) of the flow direction of the sheet when the front sheet is manufactured, and is also in the longitudinal direction X of the sanitary napkin 1 (refer to FIG. 1). The same direction. Moreover, the Y direction in FIG. 3 is the same direction as the flow direction (MD) of the sheet at the time of manufacture of the front sheet, and is also the same direction as the horizontal direction Y (refer FIG. 1) of the sanitary napkin 1.

若進而對正面片材2進行說明，則正面片材2例如包含單層構造或多層構造之不織布等纖維片材，且其肌膚對向面2a之整個區域如圖3所示般具有凹凸形狀，該凹凸形狀分別具有多個形成為斜格子狀之凹陷部20及由該凹陷部20包圍之凸部21。另一方面，正面片材2之非肌膚對向面2b實質上不具有凹凸形狀，成為大致平坦。 When the front sheet 2 is further described, the front sheet 2 includes, for example, a fiber sheet such as a nonwoven fabric of a single layer structure or a multilayer structure, and the entire area of the skin facing surface 2a has an uneven shape as shown in FIG. Each of the uneven shapes has a plurality of depressed portions 20 formed in a diagonal lattice shape and convex portions 21 surrounded by the depressed portions 20. On the other hand, the non-skin opposing surface 2b of the front sheet 2 has substantially no uneven shape and is substantially flat.

凹陷部20係將包含纖維片材之正面片材2之構成纖維壓接或接著而形成。作為壓接纖維之方法可列舉伴隨熱或不伴隨熱之壓擠加工、超音波壓擠加工等壓紋加工等。其結果，於正面片材2中，凹陷部20之密度變得較凸部21之密度高。由此而引起於對正面片材2施加有外力之情形時，凹陷部20容易作為變形之可撓軸發揮作用。本實施形態之正面片材2之凹陷部20係對藉由梳棉法而形成之纖維網狀物實施熱壓紋加工而形成。於凹陷部20中，正面片材2或構成該正面片材2之不織布之構成纖維即熱融黏性纖維藉由熱融黏而一體化。凹陷部20中之熱融黏性纖維之熱融黏成分熔融而不維持纖維之形態。 The depressed portion 20 is formed by crimping or structuring the constituent fibers of the front sheet 2 including the fiber sheet. Examples of the method of crimping the fibers include embossing such as pressing with or without heat, and embossing such as ultrasonic pressing. As a result, in the front sheet 2, the density of the depressed portion 20 becomes higher than the density of the convex portion 21. As a result, when an external force is applied to the front sheet 2, the recessed portion 20 easily functions as a flexible axis of deformation. The depressed portion 20 of the front sheet 2 of the present embodiment is formed by subjecting the fibrous web formed by the carding method to heat embossing. In the depressed portion 20, the front sheet 2 or the constituting fibers constituting the non-woven fabric of the front sheet 2, that is, the heat-fusible fibers are integrated by heat fusion. The hot melt adhesive component of the heat-fusible fiber in the depressed portion 20 is melted without maintaining the form of the fiber.

於正面片材2中，凹陷部20僅形成於正面片材2，未形成於鄰接於該正面片材2而配置於該正面片材2之下方之吸收體4。因此，正面片材2與吸收體4隔著凹陷部20而未接合。 In the front sheet 2, the depressed portion 20 is formed only on the top sheet 2, and is not formed on the absorber 4 disposed adjacent to the front sheet 2 adjacent to the front sheet 2. Therefore, the front sheet 2 and the absorber 4 are not joined via the recessed portion 20.

凹陷部20較佳為線狀。此處所謂「線狀」並不限於凹陷部20之形狀於俯視下為如圖3所示之直線，亦包含曲線，且各線可為連續線，或者亦可為於俯視下長方形、正方形、菱形、圓形、十字等之多 個凹部(壓紋部)實質上未隔開間隔而相連且作為整體形成連續線。「實質上未隔開間隔」係指凹部之相鄰之間隔為5mm以內。 The depressed portion 20 is preferably linear. Here, the "linear shape" is not limited to the shape of the depressed portion 20, which is a straight line as shown in FIG. 3 in plan view, and also includes a curved line, and each line may be a continuous line, or may be a rectangular shape, a square shape, or a diamond shape in plan view. , round, cross, etc. The recesses (embossed portions) are connected substantially without being spaced apart and form a continuous line as a whole. "Substantially unseparated intervals" means that the interval between adjacent portions of the concave portion is within 5 mm.

凹陷部20如圖3所示般形成為斜格子狀。更具體而言，於正面片材2，作為凹陷部20而具有相互平行且以特定之間隔形成之多條第1線狀之凹陷部20a、及相互平行且以特定之間隔形成之多條第2線狀之凹陷部20b，且第1線狀之凹陷部20a與第2線狀之凹陷部20b構成特定之角度而相互交叉。第1線狀之凹陷部20a及第2線狀之凹陷部20b均沿分別與縱方向X及橫方向Y交叉之方向(即斜方向)直線狀地延伸。第1線狀之凹陷部20a之寬度與第2線狀之凹陷部20b之寬度可相同，或者亦可不同。第1線狀之凹陷部20a彼此間之間隔與第2線狀之凹陷部20b彼此間之間隔可相同，或者亦可不同。 The recessed portion 20 is formed in a diagonal lattice shape as shown in FIG. More specifically, the front sheet 2 has a plurality of first linear recessed portions 20a which are formed parallel to each other and which are formed at a predetermined interval, and a plurality of strips which are formed in parallel with each other at a predetermined interval. In the two-line recessed portion 20b, the first linear recessed portion 20a and the second linear recessed portion 20b form a specific angle and intersect each other. Each of the first linear recessed portion 20a and the second linear recessed portion 20b extends linearly in a direction intersecting the longitudinal direction X and the lateral direction Y (that is, an oblique direction). The width of the first linear recessed portion 20a may be the same as or different from the width of the second linear recessed portion 20b. The interval between the first linear recess portions 20a and the second linear recess portions 20b may be the same or different.

各個劃分區域22係周圍分別由線狀之凹陷部20包圍之區域，於俯視下為菱形形狀。各個劃分區域22之面積例如較佳為0.25cm2以上且2cm2以下。劃分區域22於俯視下可形成為相較縱方向X而於橫方向Y更長之菱形形狀。或者，亦可與此相反，形成為相較橫方向Y而於縱方向X上更長之菱形形狀。於劃分區域22呈於衛生棉1之橫方向Y上較長之形狀之情形時，形成有多個凹陷部20之正面片材2於橫方向Y保持較高之剛性，藉此有效地防止衛生棉1之穿著狀態下之褶皺或皺紋。衛生棉1之穿著狀態下之褶皺或皺紋主要起因於夾於穿著者之兩大腿部間之衛生棉1被該大腿部自橫方向Y擠壓，若正面片材2於橫方向Y保持較高之剛性，則即便自橫方向Y被擠壓亦容易維持衛生棉1之形狀，而不易產生褶皺或皺紋。 Each of the divided regions 22 is surrounded by a linear recessed portion 20, and has a rhombic shape in plan view. The area of each of the divided regions 22 is, for example, preferably 0.25 cm 2 or more and 2 cm 2 or less. The divided region 22 may be formed in a rhombic shape that is longer than the longitudinal direction X and longer in the lateral direction Y in plan view. Alternatively, it may be formed in a rhombic shape which is longer than the lateral direction Y and longer in the longitudinal direction X. In the case where the divided region 22 has a long shape in the lateral direction Y of the sanitary napkin 1, the front sheet 2 on which the plurality of depressed portions 20 are formed maintains a high rigidity in the lateral direction Y, thereby effectively preventing hygiene. Wrinkles or wrinkles in the state of wearing cotton 1. The wrinkles or wrinkles in the wearing state of the sanitary napkin 1 are mainly caused by the sanitary napkin 1 sandwiched between the two thighs of the wearer being pressed by the thigh portion from the transverse direction Y, if the front sheet 2 is held in the transverse direction Y With higher rigidity, it is easy to maintain the shape of the sanitary napkin 1 even if it is pressed from the transverse direction Y, and wrinkles or wrinkles are less likely to occur.

於各劃分區域22形成有相對於包圍該劃分區域22之凹陷部20而相對性地隆起之凸部21，各劃分區域22呈於肌膚對向面2a側具備頂部21a之凸形狀。凸部21之頂部21a位於劃分區域22之中央部。凸部21內由正面片材2之構成纖維25填滿。如下述般，本發明中不排除線狀以 外之凹陷部，但自形成良好之凸部21之觀點而言，凹陷部較佳為線狀。 Each of the divided regions 22 is formed with a convex portion 21 that is relatively raised with respect to the depressed portion 20 surrounding the divided region 22, and each of the divided regions 22 has a convex shape with a top portion 21a on the skin facing surface 2a side. The top portion 21a of the convex portion 21 is located at the central portion of the divided region 22. The inside of the convex portion 21 is filled with the constituent fibers 25 of the front sheet 2. As described below, the linear shape is not excluded in the present invention. The depressed portion is external, but the depressed portion is preferably linear from the viewpoint of forming the convex portion 21.

如此，凹陷部20與凸部21分別於正面片材2之縱方向X及橫方向Y上交替地配置，藉此，減少衛生棉1與穿著者之肌膚之接觸面積，而有效地防止悶熱或斑疹。又，凸部21(劃分區域22)由凹陷部20包圍，且於俯視下為閉合之形狀，藉此，與凸部21未由凹陷部20包圍之情形相比，凸部21中之構成纖維容易朝向正面片材2之厚度方向伸展，因此凸部21之厚度增加，藉此，發揮如下效果等：1)液體迅速地透過，且液體殘留較少，正面片材2與肌膚之接觸面積減少；2)由於凸部21由規則之圖案形成，故而視覺印象良好。 In this manner, the recessed portion 20 and the convex portion 21 are alternately arranged in the longitudinal direction X and the lateral direction Y of the front sheet 2, thereby reducing the contact area between the sanitary napkin 1 and the wearer's skin, thereby effectively preventing sultry heat or Spotted rash. Further, the convex portion 21 (the divided portion 22) is surrounded by the depressed portion 20 and has a closed shape in plan view, whereby the constituent fibers in the convex portion 21 are compared with the case where the convex portion 21 is not surrounded by the depressed portion 20. Since it is easy to extend in the thickness direction of the front sheet 2, the thickness of the convex portion 21 is increased, thereby exerting the following effects: 1) the liquid is quickly transmitted, and the liquid remains less, and the contact area between the front sheet 2 and the skin is reduced. 2) Since the convex portion 21 is formed by a regular pattern, the visual impression is good.

於圖4中示出了吸收體4之主要部分。如圖4所示，吸收體4於排泄部對向部B具有將複數條沿著縱方向X之縱狹縫43形成為分散之狀態之排泄部狹縫區域S。縱狹縫43形成於排泄部對向部B中之多層部42、及除多層部42以外之部位之兩者。 The main part of the absorbent body 4 is shown in FIG. As shown in Fig. 4, the absorbent body 4 has a drain portion slit region S in a state in which a plurality of slits 43 are formed in a state in which the longitudinal slits 43 are dispersed in the longitudinal direction X. The vertical slits 43 are formed in the multi-layer portion 42 of the excretion portion opposing portion B and the portions other than the multi-layer portion 42.

各縱狹縫43各自獨立，非狹縫部43'位於相鄰之縱狹縫43彼此之間。而且，各縱狹縫43之周圍之整個區域由非狹縫部43'包圍。 Each of the vertical slits 43 is independent, and the non-slit portion 43' is located between the adjacent longitudinal slits 43. Moreover, the entire area around the respective longitudinal slits 43 is surrounded by the non-slit portion 43'.

縱狹縫43係對吸收體4遍及其厚度方向切出切口而形成者，且係由實質上不具有寬度之切口形成，或較佳為成為1.5mm以下之窄幅之空間。於縱狹縫43具有寬度之情形時，該寬度係指與縱狹縫43之延伸方向正交之方向上之該縱狹縫43之長度。 The vertical slit 43 is formed by cutting a slit in the thickness direction of the absorber 4, and is formed by a slit having substantially no width, or preferably a space of a narrow width of 1.5 mm or less. In the case where the longitudinal slit 43 has a width, the width means the length of the longitudinal slit 43 in the direction orthogonal to the extending direction of the longitudinal slit 43.

縱狹縫43較佳為如圖2所示般遍及厚度方向之整個區域而貫通構成吸收體4之吸收性片材之積層體。較佳為縱狹縫43未形成於配置於吸收體4之上下之正面片材2及背面片材3，且亦未形成於有時會配置於正面片材2與吸收體4之間之包含不織布之第二片材(未圖示)。 The vertical slit 43 is preferably a laminated body that penetrates the entire surface in the thickness direction as shown in FIG. 2 and penetrates the absorbent sheet constituting the absorbent body 4. It is preferable that the vertical slits 43 are not formed on the front sheet 2 and the back sheet 3 disposed above and below the absorber 4, and are not formed in the case where they are disposed between the front sheet 2 and the absorber 4. Non-woven second sheet (not shown).

如圖4之主要部分放大圖即圖5及圖6所示，於吸收體4中，包含沿衛生棉1之橫方向Y隔開之複數條縱狹縫43之狹縫行R1、R2於衛生 棉1之縱方向X上形成有複數行。圖5中示出了包含沿橫方向Y上隔開之兩條縱狹縫43之狹縫行R1與包含沿橫方向Y上隔開之3條縱狹縫43之狹縫行R2於縱方向X上交替地形成之例，但於本發明之狹縫區域S中，最低包含橫方向Y上隔開之兩條縱狹縫之狹縫行於縱方向X上形成兩行即可。但是，較佳為狹縫行於縱方向X上形成有3行以上，更佳為形成有4行以上，進而佳為形成有5行以上。又，各個狹縫行所包含之於橫方向X上隔開之縱狹縫之條數較佳為兩條以上，更佳為3條以上，進而佳為4條以上。 As shown in FIG. 5 and FIG. 6 in the enlarged view of the main part of FIG. 4, the absorbent body 4 includes slit rows R1 and R2 of a plurality of longitudinal slits 43 spaced along the transverse direction Y of the sanitary napkin 1 for hygiene. A plurality of rows are formed in the longitudinal direction X of the cotton 1. 5 shows a slit row R1 including two longitudinal slits 43 spaced apart in the lateral direction Y and a slit row R2 including three longitudinal slits 43 spaced apart in the lateral direction Y in the longitudinal direction. Although X is alternately formed, in the slit region S of the present invention, the slits including the two longitudinal slits spaced apart in the lateral direction Y may form two rows in the longitudinal direction X. However, it is preferable that the slit row is formed in three or more rows in the longitudinal direction X, more preferably four rows or more, and more preferably five rows or more. Further, the number of the slits which are spaced apart in the lateral direction X by the slit rows is preferably two or more, more preferably three or more, and still more preferably four or more.

衛生棉1之於縱方向X上相鄰之狹縫行間具有間隔P。即，於縱方向X上相鄰之兩個狹縫行R1、R2間如圖5所示般設置有間隔P。間隔P較佳為構成狹縫行之縱狹縫43之縱方向X之長度L1之50%以下，進而佳為35%以下。又，較佳為5%以上，進而佳為10%以上。 The sanitary napkin 1 has a spacing P between adjacent rows of slits in the longitudinal direction X. That is, a gap P is provided between the two slit rows R1 and R2 adjacent in the longitudinal direction X as shown in FIG. The interval P is preferably 50% or less of the length L1 of the longitudinal direction X of the slit slits constituting the slit row, and more preferably 35% or less. Further, it is preferably 5% or more, and more preferably 10% or more.

衛生棉1之於縱方向X上相鄰之狹縫行之縱狹縫43之位置於衛生棉1之橫方向Y上錯開。如圖5所示，於縱方向X上相鄰之兩個狹縫行R1、R2中之縱狹縫43，較佳為一狹縫行R1之狹縫43位於另一狹縫行R2之狹縫43間之中央部，但一狹縫行R1之狹縫43亦可偏靠另一狹縫行R2之狹縫43間之任一側而形成。圖6係表示於縱方向X上相鄰之狹縫行R1、R2之狹縫之位置於橫方向Y上未錯開之例的圖。 The position of the longitudinal slits 43 of the adjacent rows of the sanitary napkins 1 in the longitudinal direction X is shifted in the transverse direction Y of the sanitary napkin 1. As shown in FIG. 5, the longitudinal slit 43 of the two adjacent slit rows R1, R2 in the longitudinal direction X is preferably a slit 43 of the slit row R1 located at the narrowness of the other slit row R2. The central portion of the slit 43 is formed, but the slit 43 of one slit row R1 may be formed to be biased against either side between the slits 43 of the other slit row R2. Fig. 6 is a view showing an example in which the positions of the slits of the slit rows R1 and R2 adjacent in the longitudinal direction X are not shifted in the lateral direction Y.

於圖7(a)及(b)中示出了排泄部狹縫區域S之另一形態。於該等圖所示之排泄部狹縫區域S中，衛生棉1之於縱方向X上相鄰之狹縫行間不具有間隔P。即，於縱方向X上相鄰之兩個狹縫行R1、R2間未設置如圖5所示之間隔P。於相鄰之狹縫行間不具有間隔P之表述中包含如下兩種情形，即：如圖7(a)所示，相鄰之狹縫行之狹縫43之端部彼此之位置一致之情形；及如圖7(b)所示般，相鄰之狹縫行於縱方向X上一部分重疊之情形。於如圖7(b)所示般以使兩條狹縫行彼此之一部分重疊之狀態配置於縱方向X之情形時，其重疊之長度L2較佳為構成狹 縫行之縱狹縫43之縱方向X之長度L1之20%以下，進而佳為10%以下。又，較佳為1%以上，進而佳為5%以上。 Another form of the excretory portion slit region S is shown in Figs. 7(a) and (b). In the excretory section slit region S shown in the figures, the sanitary napkin 1 does not have a space P between adjacent slit rows in the longitudinal direction X. That is, the interval P shown in FIG. 5 is not provided between the two slit rows R1 and R2 adjacent in the longitudinal direction X. The expression having no interval P between adjacent slit rows includes the following two cases, that is, as shown in Fig. 7(a), the positions of the ends of the slits 43 of the adjacent slit rows are identical to each other. And as shown in FIG. 7(b), the adjacent slits are partially overlapped in the longitudinal direction X. When the two slit rows are partially overlapped with each other in the longitudinal direction X as shown in FIG. 7(b), the overlapping length L2 is preferably narrow. The length L1 of the longitudinal slits S of the slits is 20% or less, and more preferably 10% or less. Further, it is preferably 1% or more, and more preferably 5% or more.

根據本實施形態之衛生棉1，如圖4所示，包含吸收性片材之積層體之吸收體4於排泄部對向部B具有使複數條縱狹縫43形成為分散之狀態之排泄部狹縫區域S，因此，於穿著衛生棉1時，即便由穿著者之大腿部施加於橫方向X上壓縮吸收體4之力，吸收體4亦於排泄部狹縫區域S之多個部位細微變形，因此，不易於吸收體4或衛生棉1產生深度較深之折紋。因此，亦防止因較深之折紋導致穿著者感到不適感，或液體沿著折紋流動而導致漏出等。尤其是，於在排泄部狹縫區域S中之相鄰之狹縫行R1、R2間未設置圖5所示之間隔P之圖7(a)及(b)所示之情形時，縱狹縫之條數變多，因此於產生穿著者之動作等時，容易於多個部位細微地變形，因此更難以產生折紋。又，由於縱狹縫具有阻擋液體之效果，故而可控制液體向橫方向之擴散，而可抑制漏出。 In the sanitary napkin 1 of the present embodiment, as shown in FIG. 4, the absorbent body 4 including the laminated body of the absorbent sheet has a discharge portion in which the plurality of longitudinal slits 43 are dispersed in the excretion portion facing portion B. In the slit region S, when the sanitary napkin 1 is worn, even if the force of the absorbent body 4 is applied to the lateral direction X by the thigh portion of the wearer, the absorbent body 4 is also in the plurality of portions of the discharge portion slit region S. It is slightly deformed, and therefore, it is not easy to absorb the body 4 or the sanitary napkin 1 to produce a deeper crease. Therefore, it is also prevented that the wearer feels uncomfortable due to the deep crease, or the liquid flows along the crease to cause leakage or the like. In particular, when the interval P shown in FIG. 5 is not provided between the adjacent slit rows R1 and R2 in the drain portion slit region S, the case shown in FIGS. 7(a) and (b) is vertical and narrow. Since the number of slits is increased, it is easy to slightly deform a plurality of portions when a wearer's motion or the like occurs, and thus it is more difficult to generate creases. Further, since the vertical slit has the effect of blocking the liquid, it is possible to control the diffusion of the liquid in the lateral direction and to suppress leakage.

自進一步確實地獲得上述效果之觀點等而言，吸收體4較佳為具有以下一種或兩種以上之構成。 The absorber 4 preferably has one or two or more of the following configurations from the viewpoint of obtaining the above-described effects.

排泄部狹縫區域S中之縱狹縫43之長度L1(參照圖5)較佳為10mm以上，進而佳為15mm以上，又，較佳為35mm以下，進而佳為25mm以下，又，較佳為10mm以上且35mm以下，進而佳為15mm以上且25mm以下。 The length L1 (see FIG. 5) of the slits 43 in the slit portion S of the excretion portion is preferably 10 mm or more, more preferably 15 mm or more, further preferably 35 mm or less, more preferably 25 mm or less, and further preferably It is 10 mm or more and 35 mm or less, and further preferably 15 mm or more and 25 mm or less.

排泄部狹縫區域S中之同一狹縫行內之縱狹縫43之間隔L5(參照圖5)較佳為3mm以上，進而佳為5mm以上，又，較佳為20mm以下，進而佳為15mm以下，又，較佳為3mm以上且20mm以下，進而佳為5mm以上且15mm以下。 The interval L5 (see FIG. 5) of the slits 43 in the same slit row in the drain portion slit region S is preferably 3 mm or more, more preferably 5 mm or more, further preferably 20 mm or less, and further preferably 15 mm. Hereinafter, it is preferably 3 mm or more and 20 mm or less, and more preferably 5 mm or more and 15 mm or less.

排泄部狹縫區域S之橫方向Y之長度L4(參照圖4)，較佳為排泄部對向部B上之吸收體4之相同方向Y之長度之30%以上，進而佳為40% 以上，又，較佳為85%以下，進而佳為75%以下。排泄部狹縫區域S之橫方向Y之長度L4較佳為30mm以上，進而佳為40mm以上，又，較佳為55mm以下，進而佳為45mm以下。 The length L4 (see FIG. 4) of the lateral direction Y of the excretory portion slit region S is preferably 30% or more, and more preferably 40%, of the length of the absorbent body 4 in the same direction Y on the opposing portion B of the excretory portion. The above is preferably 85% or less, and more preferably 75% or less. The length L4 of the lateral direction Y of the excretory portion slit region S is preferably 30 mm or more, more preferably 40 mm or more, further preferably 55 mm or less, and further preferably 45 mm or less.

圖8中表示形成於吸收體4之縱狹縫43與形成於正面片材2之凹陷部20之位置關係。如圖8所示，於衛生棉1之俯視下，縱狹縫43與凹陷部20以特定之角度交叉。於著眼於一個縱狹縫43之情形時，該縱狹縫43與一條凹陷部20交叉，或與兩條以上之凹陷部20交叉。縱狹縫43存在與凹陷部20中之第1線狀之凹陷部20a交叉之情形，或者亦存在與第2線狀之凹陷部20b交叉之情形。或者縱狹縫43亦存在與第1線狀之凹陷部20a及第2線狀之凹陷部20b之兩者交叉之情形。 FIG. 8 shows the positional relationship between the vertical slits 43 formed in the absorbent body 4 and the depressed portions 20 formed in the front sheet 2. As shown in Fig. 8, in the plan view of the sanitary napkin 1, the longitudinal slits 43 and the recessed portions 20 intersect at a specific angle. When viewed in the case of one longitudinal slit 43, the longitudinal slit 43 intersects with one recessed portion 20 or intersects two or more recessed portions 20. The vertical slit 43 may intersect the first linear recessed portion 20a of the recessed portion 20, or may intersect the second linear recessed portion 20b. Alternatively, the vertical slits 43 may intersect with both the first linear recessed portion 20a and the second linear recessed portion 20b.

藉由縱狹縫43與凹陷部20交叉，於在衛生棉1之穿著狀態下正面片材2以凹陷部20為可撓軸而變形時，與該凹陷部20交叉之縱狹縫43會分散外力，因此，產生不易於正面片材2出現較深之皺紋之有利之效果。其結果，衛生棉1之穿著感不易降低。又，可穩定地確保衛生棉1之肌膚對向面上之吸液區域。尤其是，若凹陷部20之寬度大於縱狹縫43之寬度，則該效果進一步變得顯著。自該觀點而言，凹陷部20之寬度較佳為0.2mm以上，進而佳為0.5mm以上。又，凹陷部20之寬度較佳為1.5mm以下，進而佳為1.2mm以下。例如，凹陷部20之寬度較佳為0.2mm以上且1.5mm以下，進而佳為0.5mm以上且1.2mm以下。所謂凹陷部20之寬度係指與該凹陷部20之延伸方向正交之方向上之該凹陷部20之長度。 When the longitudinal slits 43 are intersected with the recessed portions 20, when the front sheet 2 is deformed by the recessed portion 20 in the wearing state of the sanitary napkin 1, the longitudinal slits 43 intersecting the recessed portions 20 are dispersed. The external force, therefore, produces an advantageous effect that it is not easy for the front sheet 2 to have deep wrinkles. As a result, the wearing feeling of the sanitary napkin 1 is not easily lowered. Further, it is possible to stably ensure the liquid absorbing area on the opposite surface of the skin of the sanitary napkin 1. In particular, if the width of the depressed portion 20 is larger than the width of the vertical slit 43, the effect is further remarkable. From this point of view, the width of the depressed portion 20 is preferably 0.2 mm or more, and more preferably 0.5 mm or more. Further, the width of the depressed portion 20 is preferably 1.5 mm or less, and more preferably 1.2 mm or less. For example, the width of the depressed portion 20 is preferably 0.2 mm or more and 1.5 mm or less, and more preferably 0.5 mm or more and 1.2 mm or less. The width of the depressed portion 20 means the length of the depressed portion 20 in a direction orthogonal to the extending direction of the depressed portion 20.

上述之有利效果於形成有正面片材2與吸收體4係朝向背面片材3側一體地凹陷而成之線狀槽51、61、71之情形時尤其顯著。特別是，於線狀槽中之於衛生棉1之沿著縱方向X之兩側部之位置沿著該縱方向X延伸之縱槽51(參照圖1)，以與縱狹縫43及非狹縫部43'兩者交叉之方式延伸之情形時，更有效地防止於正面片材2產生較深之皺紋。 The above advantageous effects are particularly remarkable in the case where the linear sheets 51, 61, and 71 in which the front sheet 2 and the absorbent body 4 are integrally recessed toward the side of the back sheet 3 are formed. In particular, in the linear groove, the longitudinal groove 51 (refer to FIG. 1) extending along the longitudinal direction X at the position of the both sides of the sanitary napkin 1 along the longitudinal direction X, and the longitudinal slit 43 and When the slit portion 43' is extended in such a manner as to intersect, it is more effectively prevented from generating deep wrinkles on the front sheet 2.

於圖8所示之實施形態中，凹陷部20與縱狹縫43以特定之角度(超過0度且為90度以下)交叉。如此，將凹陷部20形成為向一方向延伸之線狀之形狀，且使該凹陷部20之延伸方向與縱方向X及橫方向Y不一致，而使凹陷部20與縱狹縫43以特定之角度交叉，自可更有效地防止於正面片材2形成較深之皺紋之觀點而言較佳。自該觀點而言，凹陷部20較佳為如圖8所示般為斜格子狀。交叉角度之範圍較佳為5度以上且90度以下，進而佳為10度以上且90度以下。 In the embodiment shown in FIG. 8, the recessed portion 20 and the vertical slit 43 intersect at a specific angle (more than 0 degrees and 90 degrees or less). In this manner, the depressed portion 20 is formed in a linear shape extending in one direction, and the extending direction of the depressed portion 20 does not coincide with the longitudinal direction X and the lateral direction Y, and the depressed portion 20 and the longitudinal slit 43 are specified. The angle crossing is preferable from the viewpoint of more effectively preventing the front sheet 2 from forming deep wrinkles. From this point of view, the depressed portion 20 is preferably in the form of a diagonal lattice as shown in FIG. The range of the intersecting angle is preferably 5 degrees or more and 90 degrees or less, and more preferably 10 degrees or more and 90 degrees or less.

若返回圖4，則如圖4所示，吸收體4於位於較排泄部對向部B更靠後方之後方部C具有沿著與衛生棉1之縱方向X交叉之方向延伸之複數條後方狹縫45。該後方狹縫45具有如下俯視形狀，即，狹縫45之長度方向之中央部45a之位置，位於較該長度方向之兩端部45b、45b之位置更靠前方部A側，更佳為具有朝向前方部A側凸出地彎曲之俯視形狀。又，後方狹縫45於衛生棉1之縱方向X上隔開間隔而形成有複數條。進而，如圖4所示，後方狹縫45之衛生棉1之橫方向Y上之長度L3較排泄部狹縫區域S之相同方向Y之長度L4短。 Returning to Fig. 4, as shown in Fig. 4, after the absorbent body 4 is located further rearward than the opposing portion B of the excretory portion, the square portion C has a plurality of rear portions extending in a direction crossing the longitudinal direction X of the sanitary napkin 1. Slit 45. The rear slit 45 has a plan view in which the position of the central portion 45a in the longitudinal direction of the slit 45 is located closer to the front portion A than the positions of the end portions 45b and 45b in the longitudinal direction, and more preferably It has a planar shape which is convexly curved toward the front portion A side. Further, a plurality of rear slits 45 are formed at intervals in the longitudinal direction X of the sanitary napkin 1. Furthermore, as shown in FIG. 4, the length L3 of the sanitary napkin 1 of the rear slit 45 in the lateral direction Y is shorter than the length L4 of the same direction Y of the drain portion slit region S.

藉由形成複數條後方狹縫45，即便於自排泄部對向部B之後端部附近至後方部C之必須承受來自大腿部之力並且配合身體之形狀而向前後方向彎曲之部位，吸收體4及衛生棉1亦容易沿著穿著者之動作或身體形狀而變形。因此，即便使用包含吸收性片材之積層體之吸收體4，亦可獲得優異之服貼性、漏出防止性、穿著感。尤其是，藉由使後方狹縫45之長度L3較排泄部狹縫區域S之長度L4短，因自大腿部受到之力而於排泄部對向部B產生之皺紋難以自該排泄部對向部B朝向後方部C連續地形成，從而可獲得優異之服貼性、漏出防止性及穿著感。又，由於人體之臀部之溝寬(臀溝之寬度)為20mm以上且40mm以下，故而衛生棉1不會過於進入臀溝，而不易產生穿著感之劣化，因此較佳。 By forming a plurality of rear slits 45, even in the vicinity of the end portion from the rear portion B to the rear portion C of the drain portion B, it is necessary to withstand the force from the thigh portion and to match the shape of the body to bend forward and backward. The body 4 and the sanitary napkin 1 are also easily deformed along the movement of the wearer or the shape of the body. Therefore, even if the absorber 4 containing the laminated body of the absorbent sheet is used, excellent adhesiveness, leakage prevention, and wearing feeling can be obtained. In particular, by making the length L3 of the rear slit 45 shorter than the length L4 of the drain portion slit region S, it is difficult for the wrinkles generated in the opposing portion B of the excretory portion due to the force received from the thigh portion from the excretion portion. The portion B is continuously formed toward the rear portion C, whereby excellent conformability, leakage prevention, and wearing feeling can be obtained. Further, since the width of the buttocks of the human body (the width of the gluteal groove) is 20 mm or more and 40 mm or less, the sanitary napkin 1 does not excessively enter the gluteal groove, and is less likely to cause deterioration in wearing feeling, and therefore is preferable.

與排泄部對向部B同樣，於後方部C，於衛生棉1之俯視下，後方狹縫45與凹陷部20亦以特定之角度交叉。於著眼於一後方狹縫45之情形時，該後方狹縫45與一條凹陷部20交叉，或與兩條以上之凹陷部20交叉。後方狹縫45存在與凹陷部20中之第1線狀之凹陷部20a交叉之情形，或者亦存在與第2線狀之凹陷部20b交叉之情形。或者後方狹縫45亦存在與第1線狀之凹陷部20a及第2線狀之凹陷部20b兩者交叉之情形。藉由該交叉，即便於後方部C亦可有效地防止於正面片材2產生較深之皺紋。尤其是，若凹陷部20之寬度大於後方狹縫45之寬度，則該效果變得更顯著。自該觀點而言，後方狹縫45之寬度較佳為0.3mm以上，進而佳為0.5mm以上。又，較佳為1.5mm以下，進而佳為1.2mm以下。例如，後方狹縫45之寬度較佳為0.3mm以上且1.5mm以下，進而佳為0.5mm以上且1.2mm以下。所謂後方狹縫45之寬度係指與該後方狹縫45之延伸方向正交之方向上之該後方狹縫45之長度。於寬度根據後方狹縫45之位置而不同之情形時，將最寬之部分之寬度設為後方狹縫45之寬度。 Similarly to the opposing portion B of the excretory portion, in the rear portion C, the rear slit 45 and the recessed portion 20 intersect at a specific angle in a plan view of the sanitary napkin 1. The rear slit 45 intersects with one recessed portion 20 or intersects two or more recessed portions 20 when focusing on a rear slit 45. The rear slit 45 may intersect the first linear recessed portion 20a of the recessed portion 20, or may intersect the second linear recessed portion 20b. Alternatively, the rear slit 45 may intersect with both the first linear recessed portion 20a and the second linear recessed portion 20b. By this intersection, even in the rear portion C, it is possible to effectively prevent the front sheet 2 from generating deep wrinkles. In particular, if the width of the depressed portion 20 is larger than the width of the rear slit 45, the effect becomes more remarkable. From this point of view, the width of the rear slit 45 is preferably 0.3 mm or more, and more preferably 0.5 mm or more. Further, it is preferably 1.5 mm or less, and more preferably 1.2 mm or less. For example, the width of the rear slit 45 is preferably 0.3 mm or more and 1.5 mm or less, and more preferably 0.5 mm or more and 1.2 mm or less. The width of the rear slit 45 means the length of the rear slit 45 in the direction orthogonal to the extending direction of the rear slit 45. When the width differs depending on the position of the rear slit 45, the width of the widest portion is set as the width of the rear slit 45.

自使上述效果更顯著之觀點而言，後方狹縫45之橫方向Y之長度L3較佳為具有該後方狹縫45之部位上之吸收體4之相同方向Y之長度的30%以上，進而佳為40%以上，又，較佳為65%以下，進而佳為55%以下。又，後方狹縫45之上述橫方向Y之長度L3較佳為30mm以上，進而佳為40mm以上，又，較佳為55mm以下，進而佳為45mm以下。 From the viewpoint of making the above effect more remarkable, the length L3 of the lateral direction Y of the rear slit 45 is preferably 30% or more of the length of the same direction Y of the absorber 4 at the portion of the rear slit 45, and further Preferably, it is 40% or more, and more preferably, it is 65% or less, and further preferably 55% or less. Further, the length L3 of the rear slit 45 in the lateral direction Y is preferably 30 mm or more, more preferably 40 mm or more, further preferably 55 mm or less, and further preferably 45 mm or less.

又，於吸收體4之後方部C，於著眼於在縱方向X上相鄰之兩個後方狹縫45之情形時，位於前方側之後方狹縫45之後端位置與位於後方側之後方狹縫45之前端位置之間之距離L8(參照圖4)較佳為2mm以上，進而佳為4mm以上，又，自向臀部之服貼性之觀點而言，較佳為10mm以下，進而佳為7mm以下。例如，L8較佳為2mm以上且10 mm以下。 Further, in the case where the rear portion C of the absorber 4 is focused on the two rear slits 45 adjacent in the longitudinal direction X, the rear end portion is located at the rear end side of the slit 45 and the rear side is located at the rear side. The distance L8 (refer to FIG. 4) between the positions of the front end of the slit 45 is preferably 2 mm or more, and more preferably 4 mm or more, and is preferably 10 mm or less from the viewpoint of the conformability to the buttocks, and further preferably 7mm or less. For example, L8 is preferably 2 mm or more and 10 Below mm.

本實施形態之衛生棉1之吸收體4如上所述於排泄部對向部B具有多層部42，且排泄部狹縫區域S形成於包含該多層部42之區域。另一方面，後方狹縫45形成於位於多層部42之後方之吸收性片材之積層片數較該多層部42少之部位。由此引起相對於在衛生棉1之穿著狀態下該衛生棉1自大腿部等受到之外部壓力，而後方狹縫45之寬度容易變大。其結果，發揮如下有利之效果，即，可使後方狹縫45相對於穿著者之複雜之身體形狀而有彈性地變形誘導。 The absorbent body 4 of the sanitary napkin 1 of the present embodiment has the multi-layered portion 42 in the excretory portion opposing portion B as described above, and the excretory portion slit region S is formed in the region including the multi-layered portion 42. On the other hand, the rear slit 45 is formed in a portion where the number of laminated sheets of the absorbent sheet located behind the multilayered portion 42 is smaller than that of the multilayered portion 42. This causes external pressure to be applied to the sanitary napkin 1 from the thigh portion or the like in the wearing state of the sanitary napkin 1, and the width of the rear slit 45 is likely to become large. As a result, there is an advantageous effect that the rear slit 45 can be elastically deformed and induced with respect to the complicated body shape of the wearer.

若具體地說明本發明之更佳之實施形態，則於正面片材2與吸收體4之間配置有第二片材(未圖示)，凹陷部20僅設置於正面片材2，於吸收體4之多層部42形成縱狹縫43，而且第二片材設為既未設置凹陷部20亦未設置縱狹縫43之平坦之構造。藉由設為此種構造，更容易抑制於正面片材2側產生皺紋，並且流經正面片材2之表面之凹處之體液容易順利地流至吸收體4。 When a preferred embodiment of the present invention is specifically described, a second sheet (not shown) is disposed between the front sheet 2 and the absorber 4, and the recessed portion 20 is provided only on the front sheet 2 in the absorbent body. The multi-layer portion 42 of the fourth portion 42 forms the vertical slit 43, and the second sheet material has a flat structure in which neither the recess portion 20 nor the vertical slit 43 is provided. With such a configuration, it is easier to suppress generation of wrinkles on the side of the front sheet 2, and the body fluid flowing through the concave portion of the surface of the front sheet 2 easily flows smoothly to the absorber 4.

若對衛生棉1中之各部分之形成材料進行說明，則作為背面片材3，可無特別限制地使用該技術領域中先前所使用之各種材料。例如，可使用液體不透過性之材料或撥水性之材料。作為液體不透過性之材料可使用樹脂薄膜、或具有微細孔，且具有透濕性之樹脂薄膜、及樹脂薄膜與不織布等之層壓材等，作為撥水性之材料可使用包含紡黏‧熔噴‧紡黏等之多層構造之複合不織布、紡黏不織布、熱黏不織布、通氣不織布等。 When the material for forming each part of the sanitary napkin 1 is described, various materials previously used in the technical field can be used as the back sheet 3 without any particular limitation. For example, a liquid impervious material or a water repellent material can be used. As the material for liquid impermeability, a resin film or a resin film having micropores and having moisture permeability, a laminate of a resin film and a non-woven fabric, or the like can be used, and as a water-repellent material, a spun bond can be used. A composite non-woven fabric, a spunbonded non-woven fabric, a thermo-bonded non-woven fabric, a ventilated non-woven fabric, and the like having a multi-layer structure such as a spray and a spunbond.

作為構成吸收體4之吸收性片材401~403，可較佳地使用經由濕潤狀態之吸水性聚合物中產生之黏著力或另行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而形成片材狀者等。又，作為吸收性片材，可使用如下等，即：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；於使隨 著氣流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使高吸收性聚合物分散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。可將一片該等吸收性片材裁斷為特定形狀而作為片材狀吸收體使用。 As the absorbent sheets 401 to 403 constituting the absorbent body 4, it is preferable to use an adhesive force generated in a water-absorbent polymer in a wet state or an adhesive agent or an adhesive which is additionally added to form an interfiber. Or a combination of a constituent fiber and a water-absorptive polymer to form a sheet shape or the like. In addition, as the absorbent sheet, an absorbent sheet produced by the method described in JP-A-H08-246395 can be used. After the pulverized pulp and the water-absorbing polymer which are supplied by the airflow are deposited, the dry sheet is fixed by an adhesive (for example, a vinyl acetate-based adhesive, PVA (polyvinyl alcohol) or the like); between paper or non-woven fabric An absorbent sheet obtained by dispersing a superabsorbent polymer after application of a hot-melt adhesive or the like; and an absorbent sheet obtained by disposing a superabsorbent polymer in a spunbond or melt-blown nonwoven fabric manufacturing step. One of the absorbent sheets can be cut into a specific shape and used as a sheet-like absorbent.

本發明中之吸收性片材之積層體可為將單張之吸收性片材貼合複數片進行積層而成者，亦可為將一片吸收性片材摺疊並且將該等之層間接著而製成積層體者。又，亦可為將此種積層體夾於兩片吸收性片材間或摺疊而製成為兩層以上之積層體之層間，或積層於其他吸收性片材之肌膚對向面側或非肌膚對向面側而成者。又，吸收性片材之摺疊方法亦可採用多種摺疊方法，例如，上述實施形態中之輔助吸收體亦可為將吸收性片材403以如圖9(a)~圖9(d)所示之摺疊方法摺疊而成者。 In the laminate of the absorbent sheet of the present invention, a single sheet of the absorbent sheet may be laminated by laminating a plurality of sheets, or a sheet of the absorbent sheet may be folded and the layers may be laminated. A layered body. Further, the laminated body may be sandwiched between two sheets of absorbent sheets or folded to form a layer of two or more layers, or laminated on the opposite side of the skin of other absorbent sheets or non-skin. The opposite side is made up. Further, the folding method of the absorbent sheet may be carried out by various folding methods. For example, the auxiliary absorbent body in the above embodiment may be such that the absorbent sheet 403 is as shown in Figs. 9(a) to 9(d). The folding method is folded.

吸收體4之多層部42之厚度較佳為0.7mm以上，尤其較佳為1mm以上，又，較佳為5mm以下，進而佳為4mm以下。更具體而言，較佳為0.7mm以上且5mm以下，進而佳為1mm以上且4mm以下。藉由設為該範圍，容易同時實現排泄部對向部B上之良好之穿著感與較高之吸收性能。又，於衛生棉1具備側翼部7之情形時，容易抑制於穿著衛生棉1時排泄部對向部C上之吸收體4產生褶皺。 The thickness of the multilayer portion 42 of the absorber 4 is preferably 0.7 mm or more, particularly preferably 1 mm or more, more preferably 5 mm or less, and still more preferably 4 mm or less. More specifically, it is preferably 0.7 mm or more and 5 mm or less, and more preferably 1 mm or more and 4 mm or less. By setting it as this range, it is easy to achieve the favorable wearing feeling and the high absorption performance on the opposing part B of the excretion part simultaneously. Further, when the sanitary napkin 1 is provided with the side flap portion 7, it is easy to suppress wrinkles of the absorbent body 4 on the opposing portion C of the excretion portion when the sanitary napkin 1 is worn.

吸收體4之除多層部42以外之部分之厚度較佳為0.3mm以上，尤其較佳為0.5mm以上，又，較佳為3mm以下，尤其較佳為2.5mm以下。更具體而言，較佳為0.3mm以上且3mm以下，進而佳為0.5mm以上且2.5mm以下。若為該範圍，則自可提高較高之吸收性能及對穿著者之動作之追隨性之觀點而言較佳。 The thickness of the portion of the absorber 4 other than the multilayer portion 42 is preferably 0.3 mm or more, particularly preferably 0.5 mm or more, more preferably 3 mm or less, and particularly preferably 2.5 mm or less. More specifically, it is preferably 0.3 mm or more and 3 mm or less, and more preferably 0.5 mm or more and 2.5 mm or less. If it is this range, it is preferable from the viewpoint of improving the high absorption performance and the followability of the wearer's action.

又，吸收體4之多層部42之厚度與除該多層部42以外之部分之分 界線附近之厚度差較佳為2mm以下，進而佳為1.5mm以下。其原因係為了抑制於排泄部對向部B上，在多層部42與其周邊部分之僅存在下層吸收體40之區域之分界附近產生褶皺。若該厚度差較大，則於在穿著狀態下衛生棉1追隨穿著者之動作時，欲填埋由厚度差所致之間隙，因此其結果，有時因厚度差之影響而容易產生褶皺，但藉由將厚度差設為上述值以下，抑制排泄部對向部B上之褶皺之產生之效果提高。吸收體4上之各部分之厚度之測定方法係如下所述。 Further, the thickness of the multilayer portion 42 of the absorber 4 and the portion other than the multilayer portion 42 are divided. The difference in thickness near the boundary is preferably 2 mm or less, and more preferably 1.5 mm or less. The reason for this is that wrinkles are generated in the vicinity of the boundary between the multi-layered portion 42 and the region of the peripheral portion where only the lower layer absorber 40 exists, in order to suppress the opposing portion B of the excretory portion. When the difference in thickness is large, when the sanitary napkin 1 follows the action of the wearer in the wearing state, the gap due to the difference in thickness is to be filled, and as a result, wrinkles are likely to occur due to the influence of the thickness difference. However, by setting the thickness difference to be equal to or less than the above value, the effect of suppressing the occurrence of wrinkles on the opposing portion B of the excretion portion is improved. The method for measuring the thickness of each portion on the absorbent body 4 is as follows.

<厚度測定方法> <Measurement method of thickness>

將吸收體4以不存在皺紋或折彎之方式靜置於水平之場所，並測定5cN/cm2之負荷下之厚度。於測定厚度時，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之間之測定部分配置平板(厚度5mm左右之壓克力板)，以負荷成為5cN/cm2之方式調整平板之大小。平板之形狀設為圓形或正方形。 The absorbent body 4 was allowed to stand at a level where no wrinkles or bends were present, and the thickness under a load of 5 cN/cm 2 was measured. For the thickness measurement, a thickness gauge PEACOCK DIAL UPRIGHT GAUGES R5-C (manufactured by OZAKI MFG. CO. LTD.) was used. At this time, a flat plate (acrylic plate having a thickness of about 5 mm) was placed on the measurement portion between the end portion of the thickness gauge and the object to be measured, and the size of the flat plate was adjusted so that the load became 5 cN/cm 2 . The shape of the flat plate is set to a circle or a square.

為於吸收體4形成狹縫，只要藉由公知之切斷方法而將吸收性片材之積層體局部性地切斷即可，例如，可使用如下切斷裝置，其具備：切割輥，其於輥之周面上，使沿周向延伸之切斷刃於輥之周向及軸長方向上分散而形成有多個；及砧輥，其承接該切割輥之刃。 In order to form a slit in the absorber 4, the laminate of the absorbent sheet may be partially cut by a known cutting method. For example, a cutting device including a cutting roll may be used. On the circumferential surface of the roller, a plurality of cutting blades extending in the circumferential direction are dispersed in the circumferential direction and the axial direction of the roller to form a plurality of; and an anvil roller receives the blade of the cutting roller.

And its saponified compound, polyaspartic acid and the like.

作為側片材10，可無特別限制地使用該技術領域中先前使用之各種材料，例如可使用液體不透過性或撥水性之樹脂薄膜、樹脂薄膜與不織布之積層體等。作為其他材料例如可列舉紡黏不織布、紡黏不織布(S)與熔噴不織布(M)複合化而成之片材(例如SM、SMS、SMMS等)、熱軋不織布、通氣不織布等撥水性(疏水性)不織布。尤其是使用 撥水性之通氣不織布自肌膚觸感佳及防止側漏之方面而言較佳。 As the side sheet 10, various materials previously used in the art can be used without particular limitation, and for example, a liquid impervious or water-repellent resin film, a laminate of a resin film and a non-woven fabric, or the like can be used. Examples of other materials include water-repellent materials such as a spunbonded nonwoven fabric, a spunbonded nonwoven fabric (S) and a melt-blown nonwoven fabric (M) (for example, SM, SMS, SMMS, etc.), a hot-rolled nonwoven fabric, and a ventilated nonwoven fabric ( Hydrophobic) Non-woven. Especially use Water-repellent ventilation non-woven fabric is preferred from the viewpoint of good skin feel and prevention of side leakage.
