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.

為了防止經期衛生棉或失禁護墊等吸收性物品之側漏，考慮使吸收性物品或其吸收體之寬度較寬地構成而增加吸收容量。然而，於僅擴寬吸收體之寬度之情形時，有吸收體之側部自短褲等衣物之褲襠部之側緣延伸，而將翼形部以翻折至褲襠部之方式固定時之作業性變差，或於自褲襠部伸出之部分產生褶皺而使穿著感惡化之虞。褶皺並非以服貼性等性能提高之目的產生之變形，而是不理想之變形。 In order to prevent side leakage of an absorbent article such as a menstrual napkin or an incontinence pad, it is conceivable to increase the absorbent capacity by making the width of the absorbent article or the absorbent body wider. However, in the case where only the width of the absorbent body is widened, the side portion of the absorbent body extends from the side edge of the crotch portion of the garment such as a shorts, and the workability when the wing portion is folded to the crotch portion is fixed. Deterioration, or wrinkles in the portion protruding from the crotch portion to deteriorate the wearing feeling. Wrinkles are not deformations that are produced for the purpose of improving performance such as conformity, but are not ideal deformations.

又，已知有於吸收體形成狹縫或開口之技術。 Further, a technique of forming a slit or an opening in an absorbent body is known.

例如，於專利文獻1中記載，於吸收體中之除去周邊以外之部分，以特定之間隔形成具有特定之長度之4行以上之狹縫。 For example, Patent Document 1 discloses that slits having a specific length of four or more rows are formed at specific intervals in portions other than the periphery of the absorber.

又，於專利文獻2中記載，於由正面片材及液體吸收層接合而成之接合圖案包圍之低剛性部，形成複數個切口部。 Further, Patent Document 2 discloses that a plurality of slit portions are formed in a low rigidity portion surrounded by a joint pattern in which a front sheet and a liquid absorbing layer are joined.

本發明者等人對在吸收體呈分散狀態形成狹縫而提高吸收體之柔軟性一事進行了研究，得知，若於吸收體形成狹縫，則於一面拉伸 翼形部一面將其固定於褲襠部時，狹縫開口，正面片材自吸收體分離而引起吸收阻礙，故而產生如下等不良情況，即，無法向吸收體順利地移行之***液殘留於正面片材而給穿著者以濕潤感，或產生液體積存而使液體於正面片材之表面流動而易產生液體漏出。 The present inventors have studied the formation of a slit in a dispersed state of the absorbent body to improve the flexibility of the absorbent body, and it has been found that when the absorbent body is formed into a slit, it is stretched on one side. When the wing portion is fixed to the crotch portion, the slit is opened, and the front sheet is separated from the absorbent body to cause absorption hindrance. Therefore, there is a problem that the excretion liquid which cannot smoothly move to the absorbent body remains on the front side. The sheet gives the wearer a moist feeling or a liquid volume to cause the liquid to flow on the surface of the front sheet to easily leak liquid.

於專利文獻1中，關於形成於吸收體之狹縫，分別個別地揭示有沿著吸收體之長度方向形成狹縫者、及沿著寬度方向形成狹縫者，關於沿著長度方向之狹縫係跨及吸收體之大致全長而連續地形成。即便於吸收體以沿著其長度方向之方式設置有狹縫，亦有易產生沿吸收性物品之長度方向延伸之皺折，而因該皺折導致穿著者感覺到不適感或引起漏出之虞。 In the slits formed in the absorbent body, the slits formed along the longitudinal direction of the absorbent body and the slits formed along the width direction are individually disclosed in the slits of the absorbent body, and the slits along the longitudinal direction are separately disclosed. The cross-over and the absorbent body are formed continuously over substantially the entire length. That is, the absorbent body is provided with slits along the longitudinal direction thereof, and wrinkles extending along the longitudinal direction of the absorbent article are easily generated, and the wrinkles cause the wearer to feel uncomfortable or cause leakage. .

專利文獻2之技術係利用正面片材補強低剛性部而保持液體吸收層之強度之技術。於專利文獻2中亦未記載既提高使用翼形部固定時之作業性或穿著感、且亦防止因狹縫之開口導致之不良情況的方法。 The technique of Patent Document 2 is a technique for reinforcing the strength of the liquid absorbing layer by reinforcing the low rigidity portion with the front sheet. Further, Patent Document 2 does not describe a method for improving the workability and wearing feeling when the wing portion is fixed, and also preventing the problem caused by the opening of the slit.

因此，本發明係關於一種可解決先前技術所具有之解決問題之吸收性物品。 Accordingly, the present invention is directed to an absorbent article that solves the problems of the prior art.

藉由配置與縱槽51重疊之狹縫，可適度地抑制在衛生棉1之橫向Y上較縱槽51更靠外側之狹縫及較該縱槽51更靠內側之狹縫(中央狹縫區域S1之狹縫)之兩者之開口。又，與縱槽51重疊之狹縫可藉由抑制將來自在較縱槽51更靠外側之區域產生之褶皺之影響傳遞至較縱槽51更靠內側之區域，而維持中央狹縫區域S1之柔軟性、或物品向身體之易服帖性。另一方面，根據該構成，可提高衛生棉1之沿著縱向X之兩側部之服貼性及翼形部之操作性之兩者。就進一步確實地取得該等效果之觀點而言，相較於狹縫之全長重疊，縱狹縫43與縱槽51較佳為部分地重疊之情形。就此點而言，相較於與縱狹縫43並行之直線之形狀，中央狹縫區域S1內之縱槽51較佳為具有曲線部或彎曲部之波線狀或如圖3所示之具有平緩之傾斜部之槽形狀。 By arranging the slits that overlap the vertical grooves 51, the slits on the outer side of the longitudinal grooves 51 in the lateral direction Y of the sanitary napkin 1 and the slits on the inner side of the longitudinal grooves 51 can be appropriately suppressed (the central slit) The opening of both of the slits of the region S1. Further, the slit overlapping the vertical groove 51 can maintain the central slit region S1 by suppressing the influence of the wrinkles generated from the region outside the longitudinal groove 51 to the inner side of the longitudinal groove 51. Softness, or the object is easy to conform to the body. On the other hand, according to this configuration, both the conformability of the sanitary napkin 1 along both sides in the longitudinal direction X and the operability of the wing portion can be improved. From the viewpoint of further obtaining such effects, the vertical slits 43 and the vertical grooves 51 preferably partially overlap each other as compared with the entire length of the slit. In this regard, the longitudinal groove 51 in the central slit region S1 preferably has a wavy shape having a curved portion or a curved portion or a gentle shape as shown in FIG. 3 as compared with the shape of a straight line parallel to the longitudinal slit 43. The groove shape of the inclined portion.

根據本實施形態之衛生棉1，吸收體4於***部對向部B具有***部狹縫區域S，該***部狹縫區域S係沿著縱向之複數個縱狹縫43形成為向縱向X及橫向Y之兩個方向分散之狀態而成，並且於吸收體4之兩側部具有位於較縱槽51、51之位置更靠外側而不與縱槽51重疊之縱狹縫43f、43g，故而於將翼形部7、7以翻折至短褲等衣物之褲襠部之方式固定時，吸收體4之側部藉由各部之縱狹縫而靈活地變形，因此使用翼形部固定時之作業性優異。此時，由於縱槽51位於較縱狹縫 43f、43g更靠內側，故而藉由其剛性可提高狹縫部分之變形容易度，且抑制其他部位之變形。又，由於在中央狹縫區域S1之兩側具有與縱槽51重疊之縱狹縫43a~43e，故而吸收體4於橫向Y上之具有縱槽51之部位亦易於變形，故而使將翼形7、7固定於短褲等之褲襠部時之操作性更加優異。尤其，於***部對向部B，就藉由不與縱槽51重疊之縱狹縫43f、43g而實現之翼形7、7之操作性提高而言較佳為，如圖3所示般縱槽51為向內側呈凸狀之曲線形狀。 According to the sanitary napkin 1 of the present embodiment, the absorbent body 4 has the excretion portion slit region S in the excretion portion opposing portion B, and the excretion portion slit region S is formed in the longitudinal direction by a plurality of longitudinal slits 43 in the longitudinal direction. And a state in which the two directions of the lateral direction Y are dispersed, and the longitudinal slits 43f and 43g which are located outside the longitudinal grooves 51 and 51 and do not overlap the longitudinal grooves 51 are provided on both sides of the absorber 4, Therefore, when the wing portions 7 and 7 are folded to the crotch portion of the garment such as the shorts, the side portions of the absorbent body 4 are flexibly deformed by the longitudinal slits of the respective portions, so that when the wing portions are fixed, Excellent workability. At this time, since the longitudinal groove 51 is located in the longitudinal slit Since 43f and 43g are further on the inner side, the rigidity of the slit portion can be improved by the rigidity thereof, and deformation of other portions can be suppressed. Further, since the longitudinal slits 43a to 43e overlapping the vertical grooves 51 are provided on both sides of the central slit region S1, the portion of the absorbent body 4 having the longitudinal grooves 51 in the lateral direction Y is also easily deformed, so that the wing shape is formed. 7, 7 is more excellent in operability when it is fixed to the crotch portion of the shorts or the like. In particular, in the opposing portion B of the excretory portion, it is preferable that the operability of the airfoil 7 and 7 is improved by the vertical slits 43f and 43g which are not overlapped with the vertical groove 51, as shown in FIG. The vertical groove 51 has a curved shape that is convex toward the inside.

又，於本實施形態之衛生棉1中，在中央狹縫區域S1之前後，具有與前方橫槽52或後方橫槽54交叉之縱狹縫43h及43i，進而在中央狹縫區域S1之兩側，具有與縱槽51重疊之縱狹縫43a~43e，故而吸收體4於縱向X上之具有前方橫槽52及後方橫槽54之部位、或橫向Y上之具有縱槽51之部位亦易於變形，因此使將翼形7、7固定於短褲等之褲襠部時之操作性更加優異。又，此種構成亦可有效地防止於吸收體4之側部產生褶皺，而使本實施形態之衛生棉1之穿著感亦優異。相對於此，於在較縱槽51、51更靠外側不具有縱狹縫之情形時，吸收體4於縱槽51之位置較大程度地變形，而於吸收體4之側部易於產生褶皺。 Further, in the sanitary napkin 1 of the present embodiment, before and after the center slit region S1, the slits 43h and 43i intersecting the front lateral groove 52 or the rear lateral groove 54 and the second slit region S1 are further provided. The side has longitudinal slits 43a to 43e overlapping the longitudinal grooves 51. Therefore, the portion of the absorbent body 4 having the front lateral groove 52 and the rear lateral groove 54 in the longitudinal direction X or the longitudinal groove 51 in the lateral direction Y is also Since it is easy to deform, the operability in fixing the wing shapes 7, 7 to the crotch portion of the shorts or the like is further improved. Moreover, such a configuration can also effectively prevent wrinkles from occurring on the side portions of the absorbent body 4, and the sanitary napkin 1 of the present embodiment is also excellent in wearing feeling. On the other hand, when there is no longitudinal slit on the outer side of the longitudinal grooves 51 and 51, the position of the absorber 4 is largely deformed at the position of the longitudinal groove 51, and wrinkles are likely to occur on the side of the absorbent body 4. .

***部狹縫區域S亦可自***部對向部B向前方部A及後方部C之至少一者延伸，***部狹縫區域S亦較佳為於位於前方部A及後方部C之部分具有與縱槽51重疊之縱狹縫。 The excretory portion slit region S may extend from the excretory portion opposing portion B to at least one of the front portion A and the rear portion C, and the excretory portion slit region S is also preferably located at the front portion A and the rear portion C. There is a longitudinal slit that overlaps the longitudinal groove 51.

又，於本實施形態之衛生棉1中，在前方橫槽52、後方橫槽54及縱槽51之各位置，將縱狹縫43配置為與該等各位置交叉或者一部分或全部重疊之狀態。因此，即便在橫向Y上對衛生棉1施加張力，亦可藉由在各狹縫之兩側結合有正面片材2或配置於其下之第二片材等，抑制該等狹縫之開口。又，藉由抑制與前方橫槽52、後方橫槽54交叉之縱狹縫43h、43i之開口，亦在某種程度上抑制位於中央狹縫區域S1之縱狹縫43之開口。因此，可防止於各部之縱狹縫開口之情形時易產 生之吸收阻礙，從而亦防止因殘留於正面片材之液體而導致穿著者感到濕潤感、或易產生液體漏出。 Further, in the sanitary napkin 1 of the present embodiment, the vertical slits 43 are disposed at positions overlapping the respective positions or partially or completely at the respective positions of the front lateral groove 52, the rear lateral groove 54, and the vertical groove 51. . Therefore, even if tension is applied to the sanitary napkin 1 in the lateral direction Y, the opening of the slits can be suppressed by combining the front sheet 2 or the second sheet disposed therebelow on both sides of each slit. . Further, by suppressing the openings of the vertical slits 43h and 43i that intersect the front lateral groove 52 and the rear lateral groove 54, the opening of the longitudinal slit 43 located in the central slit region S1 is also suppressed to some extent. Therefore, it is easy to prevent the production of the longitudinal slits of the respective sections. The absorption of the raw material is hindered, so that the wearer feels moist or leaks due to the liquid remaining on the front sheet.

就進一步確實地獲得上述效果之觀點等而言，吸收體4較佳為具有以下之一個或二個以上之構成。 The absorbent body 4 preferably has one or two or more of the following points in terms of obtaining the above-described effects and the like.

***部狹縫區域S中之縱狹縫43之長度L2(參照圖4)較佳為10mm以上，進而較佳為15mm以上，又，較佳為35mm以下，進而較佳為25mm以下，又，較佳為10~35mm，進而較佳為15~25mm。 The length L2 (see FIG. 4) of the slits 43 in the drain portion slit region S is preferably 10 mm or more, more preferably 15 mm or more, further preferably 35 mm or less, and further preferably 25 mm or less. It is preferably 10 to 35 mm, and more preferably 15 to 25 mm.

Further, it 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.

於圖1(b)中，為了避免於縱向X及橫向Y之任一方向上，縱狹縫43與表示***部狹縫區域S之單點鏈線重疊而難以看清，換言之，就觀察容易度之觀點而言，為方便起見，將***部狹縫區域S以較縱狹縫43所分佈之範圍稍大之範圍表示。然而，本發明中之***部狹縫區域S為縱狹縫43所分佈之範圍，其橫向Y之長度L4如圖1(b)所示為位於橫向Y之兩端之縱狹縫44之外緣間的距離。 In FIG. 1(b), in order to avoid the vertical slit 43 and the single-point chain line indicating the slit portion S of the excretion portion, it is difficult to see in any direction in the longitudinal direction X and the lateral direction Y, in other words, the ease of observation is observed. From the viewpoint of the convenience, the excretion slit region S is expressed by a range slightly larger than the range in which the longitudinal slits 43 are distributed. However, the excretory portion slit region S in the present invention is a range in which the longitudinal slits 43 are distributed, and the length L4 of the lateral direction Y is outside the longitudinal slits 44 at both ends of the lateral direction Y as shown in Fig. 1(b). The distance between the edges.

於中央狹縫區域S1之兩外側之各者，與縱槽51整體或一部分重疊之縱狹縫43之條數亦可為1條，但較佳為複數條，進而較佳為3條以上。又，就兼顧翼形之操作性與吸收性之方面而言，吸收體4較佳為包含具有與縱槽51重疊之部分及不重疊之部分之縱狹縫作為與縱槽51 重疊之縱狹縫。 The number of the longitudinal slits 43 that overlap the entire longitudinal groove 51 may be one in each of the outer sides of the central slit region S1, but it is preferably plural, and more preferably three or more. Further, in terms of both the operability and the absorptivity of the airfoil, the absorber 4 preferably includes a longitudinal slit having a portion overlapping the longitudinal groove 51 and a portion not overlapping as the longitudinal groove 51. Overlapping longitudinal slits.

又，於中央狹縫區域S1之兩外側之各者，位於較縱槽51更靠外側之縱狹縫之條數亦可為1條，但較佳為複數條。就防漏效果提高之方面而言，較佳為位於較縱槽51更靠外側之縱狹縫43f、43g形成於圖2所圖示之側部片材10之物品內側端部與縱槽51之間之區域。 Further, in each of the outer sides of the central slit region S1, the number of the longitudinal slits located outside the longitudinal grooves 51 may be one, but it is preferably plural. In terms of improving the leakage preventing effect, it is preferable that the longitudinal slits 43f and 43g located outside the longitudinal groove 51 are formed at the inner side end of the article and the longitudinal groove 51 of the side sheet 10 illustrated in Fig. 2 . The area between.

又，與前方橫槽52交叉之縱狹縫43h、及與後方橫槽54交叉之縱狹縫43i之條數亦可分別為1條，但較佳為分別為複數條，進而較佳為分別為3條以上。於此情形時，若與橫槽52、54交叉之縱狹縫43h、43i於橫槽之長度方向兩側各存在1條以上，則褶皺抑制效果較高，故而較佳。又，前方橫槽52及後方橫槽54較佳為與縱狹縫43h或縱狹縫43i十字狀地交叉而非T字狀地交叉。 Further, the number of the vertical slits 43h intersecting the front lateral grooves 52 and the longitudinal slits 43i intersecting the rear lateral grooves 54 may be one, but preferably plural, and preferably each It is more than three. In this case, if the longitudinal slits 43h and 43i which intersect with the lateral grooves 52 and 54 are one or more on both sides in the longitudinal direction of the lateral groove, the wrinkle suppression effect is high, which is preferable. Further, it is preferable that the front lateral groove 52 and the rear lateral groove 54 cross the vertical slit 43h or the vertical slit 43i in a cross shape instead of intersecting in a T shape.

如圖1(b)所示，本實施形態之衛生棉1之吸收體4係***部狹縫區域S之周圍被不存在狹縫之環狀之非狹縫區域N包圍。 As shown in Fig. 1(b), the absorbent body 4 of the sanitary napkin 1 of the present embodiment is surrounded by the annular non-slit region N in which the slit portion S of the excretory portion is not present.

藉由利用非狹縫區域N包圍***部狹縫區域S之周圍，可確實地防止因液體沿著縱狹縫滲入而導致之液體漏出。 By surrounding the periphery of the drain portion slit region S by the non-slit region N, it is possible to surely prevent liquid leakage due to penetration of liquid along the longitudinal slit.

又，於本實施形態之衛生棉1中，如圖3所示，中央狹縫區域S1形成於多層部42，縱狹縫43h所交叉之前方橫槽52及縱狹縫43i所交叉之後方橫槽54之橫向Y之長度L6、L7分別短於該多層部42之橫向Y之長度L8。 Further, in the sanitary napkin 1 of the present embodiment, as shown in Fig. 3, the central slit region S1 is formed in the multilayer portion 42, and the vertical slit 43h intersects before the horizontal groove 52 and the longitudinal slit 43i intersect. The lengths L6, L7 of the lateral direction Y of the groove 54 are shorter than the length L8 of the lateral direction Y of the multilayer portion 42, respectively.

藉由使前方橫槽52之長度L6及後方橫槽54之長度L7分別短於多層部42之橫向Y之長度L8，可一面抑制在吸收體4之寬度方向中央，與橫槽52、54交叉之縱狹縫43h、43i或位於橫槽52、54間之中央狹縫區域S1之縱狹縫之開口，一面良好地維持側部之服貼性。多層部42由於與***部對向，故而較佳為使***液儘可能迅速地吸收至吸收體之內部。因此，使橫槽52、54以不與位於多層部之前後之縱狹縫43h、43i重疊之方式形成，以免多層部42上之狹縫過度開口而引起吸收阻 礙。***液一旦被正面片材吸收後，便向吸收體浸透，但若過度開口，則未藉由吸收體與正面片材接著之部位增加，故而液體自***液向吸收體之移行無法順利進行。藉由預先使橫槽54之長度L7短於多層部42之橫向Y之長度L8，而令使用者不易感覺到橫槽52、54之硬度，並且不易抑制形成於多層部以外之吸收體側部之縱狹縫之開口。結果不會妨礙翼形之操作性、及穿著容易度，而無使用中之不適感。 By making the length L6 of the front lateral groove 52 and the length L7 of the rear lateral groove 54 shorter than the length L8 of the lateral direction Y of the multilayer portion 42, respectively, it is possible to suppress the intersection with the lateral grooves 52, 54 at the center in the width direction of the absorbent body 4. The longitudinal slits 43h and 43i or the slits of the longitudinal slits located in the central slit region S1 between the lateral grooves 52 and 54 satisfactorily maintain the conformability of the side portions. Since the multilayer portion 42 faces the excretion portion, it is preferable that the excretion liquid is absorbed into the inside of the absorbent body as quickly as possible. Therefore, the lateral grooves 52, 54 are formed so as not to overlap with the longitudinal slits 43h, 43i located before and after the multilayer portion, so that the slits on the multilayer portion 42 are excessively opened to cause absorption resistance. hinder. When the excretion liquid is absorbed by the front sheet, it permeates into the absorber. However, if it is excessively opened, the portion which is not incident on the front sheet by the absorber is increased. Therefore, the migration of the liquid from the excrement to the absorber cannot be smoothly performed. By making the length L7 of the lateral groove 54 shorter than the length L8 of the lateral direction Y of the multilayer portion 42, the hardness of the lateral grooves 52, 54 is hardly felt by the user, and it is difficult to suppress the side of the absorbent body formed outside the multi-layered portion. The opening of the longitudinal slit. As a result, the operability of the wing shape and the ease of wearing are not hindered, and there is no discomfort in use.

前方橫槽52之長度L6及後方橫槽54之長度L7分別相對於多層部42之橫向Y之長度L8之比率較佳為90%以下，進而較佳為85%以下，又，較佳為50%以上，進而較佳為60%以上。 The ratio of the length L6 of the front lateral groove 52 and the length L7 of the rear lateral groove 54 to the length L8 of the lateral direction Y of the multilayer portion 42 is preferably 90% or less, more preferably 85% or less, and further preferably 50. More than %, more preferably 60% or more.

於多層部42之上述長度L8在縱向X上不固定之情形時，多層部42之橫向Y之長度L8設為製品寬度方向上長度最小之部位之長度。 In the case where the length L8 of the multilayer portion 42 is not fixed in the longitudinal direction X, the length L8 of the lateral direction Y of the multilayer portion 42 is the length of the portion having the smallest length in the product width direction.

又，於本實施形態之衛生棉1中，如圖1及如圖3所示，一對縱槽51、51於較多層部42之縱向X之兩側緣更靠外側，分別形成為朝向多層部42側凸出地彎曲之形狀。 Further, in the sanitary napkin 1 of the present embodiment, as shown in Fig. 1 and Fig. 3, the pair of vertical grooves 51, 51 are formed on the outer side of the longitudinal direction X of the plurality of layer portions 42 so as to face the plurality of layers. The portion 42 is convexly curved.

為了提高衛生棉1或吸收體對於穿著者之服貼性，較佳為，將吸收體4之橫向Y之中央部作為多層部42，並使其剛性高於其兩側之形成縱槽之部分之剛性，但若多層部42與縱槽51之間之距離過大，則因剛性差而導致於多層部42與縱槽51之間之部位易產生褶皺。相對於此，藉由如本實施形態般，將縱槽51設為朝向多層部42凸出地彎曲之形狀，可防止產生此種褶皺。 In order to improve the conformability of the sanitary napkin 1 or the absorbent body to the wearer, it is preferable to use the central portion of the lateral direction Y of the absorbent body 4 as the multi-layer portion 42 and to make the rigidity higher than the portion forming the longitudinal groove on both sides thereof. Although the rigidity is too large, if the distance between the multilayer portion 42 and the vertical groove 51 is too large, wrinkles are likely to occur at a portion between the multilayer portion 42 and the vertical groove 51 due to poor rigidity. On the other hand, as in the present embodiment, the vertical groove 51 is formed to be convexly curved toward the multilayer portion 42, and such wrinkles can be prevented from occurring.

縱槽51與多層部42於***部對向部B之兩者的最接近部之分隔距離較佳為7mm以下，進而較佳為5mm以下。 The distance between the vertical groove 51 and the closest portion of the multi-layer portion 42 to the opposing portion B of the excretory portion is preferably 7 mm or less, and more preferably 5 mm or less.

圖6係表示縱槽51、前方橫槽52及後方橫槽54之較佳構成的吸收體之模式放大俯視圖。縱槽51、前方橫槽52及後方橫槽54分別於槽內具有高壓縮部56及壓縮之程度低於其之低壓縮部57，各高壓縮部56之形狀係於各槽之長度方向較長之形狀。又，前方橫槽52及後方橫槽54 之寬度W寬於縱槽51。 Fig. 6 is a schematic enlarged plan view showing an absorbent body of a preferred configuration of the vertical groove 51, the front lateral groove 52, and the rear lateral groove 54. The longitudinal groove 51, the front lateral groove 52, and the rear lateral groove 54 respectively have a high compression portion 56 in the groove and a lower compression portion 57 than the compression portion, and the shape of each high compression portion 56 is in the longitudinal direction of each groove. Long shape. Also, the front lateral groove 52 and the rear lateral groove 54 The width W is wider than the longitudinal groove 51.

對於縱槽51，將各高壓縮部56之形狀設為作為例如圖6所示之形狀的於槽之長度方向較長之形狀，藉此可容易地引導衛生棉1之沿著縱向之彎曲，從而可進一步提高服貼性。 In the vertical groove 51, the shape of each of the high-compression portions 56 is a shape that is long in the longitudinal direction of the groove, for example, as shown in Fig. 6, whereby the longitudinal bending of the sanitary napkin 1 can be easily guided. Thereby, the adaptability can be further improved.

對於前方橫槽52及後方橫槽54，將各高壓縮部56之形狀設為作為例如圖6所示之形狀的於槽之長度方向較長之形狀，藉此可進一步確實地抑制狹縫之開口，從而可進一步確實地抑制因狹縫之開口導致之不良情況。 In the front lateral groove 52 and the rear lateral groove 54, the shape of each of the high compression portions 56 is a shape having a shape as shown in FIG. 6, which is long in the longitudinal direction of the groove, whereby the slit can be further reliably suppressed. The opening makes it possible to further surely suppress the trouble caused by the opening of the slit.

對於高壓縮部56，所謂於槽之長度方向上較長之形狀係指沿著槽之方向之長度L9長於與槽正交之方向之長度L10。又，低壓縮部57可為於用以形成各槽之壓紋加工時未被直接擠壓之部位，作為高壓縮部56亦可為如圖6之較長之形狀者與如點之並非較長之形狀之形狀者交替地排列。 The shape of the high compression portion 56 that is longer in the longitudinal direction of the groove means that the length L9 along the direction of the groove is longer than the length L10 in the direction orthogonal to the groove. Moreover, the low-compression portion 57 may be a portion that is not directly pressed during embossing for forming each groove, and the high-compression portion 56 may have a longer shape as shown in FIG. The shape of the long shape is alternately arranged.

進而，藉由使前方橫槽52及後方橫槽54之寬度W寬於縱槽51之寬度W，不僅可抑制***部之狹縫之開口亦可防止***部之褶皺，從而取得可更加提高翼形之操作性且降低不適感之有利效果。 Further, by making the width W of the front lateral groove 52 and the rear lateral groove 54 wider than the width W of the vertical groove 51, it is possible to suppress not only the opening of the slit of the drain portion but also the wrinkles of the excretion portion, thereby obtaining a wing that can be further improved. The operability of the shape and the advantageous effect of reducing the discomfort.

如圖1(a)及圖2所示，本實施形態之衛生棉1之吸收體4於***部對向部B具有多層部42，***部狹縫區域S及中央狹縫區域S1形成於包含該多層部42之區域。因此，取得更加提高防漏效果及獲得跟隨身體活動之服貼性之有利效果。 As shown in Fig. 1 (a) and Fig. 2, the absorbent body 4 of the sanitary napkin 1 of the present embodiment has a multi-layer portion 42 in the excretion portion opposing portion B, and the excretion portion slit region S and the central slit region S1 are formed in the inclusion portion. The area of the multilayer portion 42. Therefore, it is advantageous to achieve a more improved leakage prevention effect and a conformity of following physical activity.

雖未圖示，但衛生棉1亦較佳為於吸收體4與正面片材2之間進而具備第二片材。第二片材較佳為其構成纖維為合成纖維之液體透過性之纖維片材。若第二片材由合成纖維構成，則可將液體之擴散性抑制得較低。又，構成第二片材之合成纖維將擴散性抑制得較低，並且就機械適合性之觀點而言，較佳為弱親水性之纖維。第二片材可將包含聚乙烯、聚丙烯、聚對苯二甲酸乙二酯、聚對苯二甲酸丁二酯等聚 酯、及尼龍-6或尼龍-66等聚醯胺等樹脂之纖維單獨、或混合2種以上而形成。再者，此處所謂之混合，包含將熔點不同之2種以上之樹脂製成芯鞘型複合纖維或並列型複合纖維而使用之情況。 Although not shown, the sanitary napkin 1 preferably further includes a second sheet between the absorbent body 4 and the topsheet 2. The second sheet is preferably a fibrous sheet in which the constituent fibers are liquid permeability of synthetic fibers. If the second sheet is composed of synthetic fibers, the diffusibility of the liquid can be suppressed to be low. Further, the synthetic fiber constituting the second sheet suppresses diffusibility to be low, and from the viewpoint of mechanical suitability, a fiber having weak hydrophilicity is preferable. The second sheet may comprise polyethylene, polypropylene, polyethylene terephthalate, polybutylene terephthalate, etc. The fibers of the resin such as an ester or a polyamide such as nylon-6 or nylon-66 are formed singly or in combination of two or more kinds. In addition, the mixing here is a case where two or more types of resins having different melting points are used as the core-sheath type composite fiber or the side-by-side type composite fiber.
