本發明係關於一種可消除上述先前技術所具有之缺點之吸收性物品。 以下，基於本發明之較佳之實施形態，一面參照圖式，一面對本發明進行說明。 於圖1及圖2中，示有作為本發明之吸收性物品之一實施形態之拋棄式尿布100(以下，亦簡稱為尿布100)之基本構造。 如圖1及圖2所示，尿布100具備液體透過性之正面片材12、液體不透過性之背面片材13、及配置於兩片材12、13之間之吸收體14。關於背面片材13，所謂液體不透過性係亦包括液體難透過性之概念，背面片材13除完全不讓液體通過之情形以外，亦包括包含撥水性之片材等之情形等。 尿布100具有：物品長度方向Xa，其係穿著時與穿著者之前後方向一致之方向；及物品寬度方向Ya，其於將尿布100如圖1所示呈平面狀鋪展之狀態下，與物品長度方向Xa正交。又，尿布100於物品長度方向Xa具有穿著時配置於穿著者之腹側之腹側部A、穿著時配置於穿著者之背側之背側部B、及位於腹側部A與背側部B之間之胯下部C。尿布100係展開型之拋棄式尿布，於背側部B之兩側緣部設置有黏扣帶17，於腹側部A之外表面，設置有固定該黏扣帶17之著扣區域18。 尿布100之吸收體14具備吸收性芯體14a及包裹該吸收性芯體14a之包芯片材14b。吸收性芯體14a可包含例如紙漿纖維等吸液性纖維之纖維堆積體、或吸液性纖維與吸水性聚合物之混合纖維堆積體。作為吸液性纖維，例如可列舉紙漿纖維、嫘縈纖維、棉纖維、乙酸纖維素等纖維素系之親水性纖維。除纖維素系之親水性纖維以外，亦可使用藉由界面活性劑等將包含聚烯烴、聚酯、聚醯胺等合成樹脂之纖維親水化而成者。作為包芯片材14b，例如可使用衛生紙或透水性之不織布。包芯片材14b既可為以1片包裹吸收性芯體14a之整體，亦可為使2片以上組合而包裹吸收性芯體14a。作為背面片材13，可使用液體不透過性或撥水性之樹脂膜、樹脂膜與不織布之層壓片材等。 於尿布100之物品長度方向Xa之兩側，配設有具有彈性構件15a之立體褶皺形成用之片材15，藉由該彈性構件15a之收縮，會於穿著狀態下之胯下部C形成向穿著者之肌膚側立起之立體褶皺。又，於胯下部C之配設於腿圍之部位，以伸長狀態配設有腿部彈性構件16，藉由其收縮，會於穿著狀態下之胯下部C形成使對穿著者之腿圍之服貼性提高之腿褶皺。 第1實施形態之拋棄式尿布100之正面片材12包含圖3所示之複合片材10。 如圖3所示，複合片材10具有沿尿布100之長度方向(物品長度方向)Xa之第1方向X、及沿尿布100之寬度方向(物品寬度方向)Ya之第2方向Y。又，如圖3所示，複合片材10具有以互不相同之圖案形成有凸部4之中央區域M、及位於該中央區域M之兩側之一對側部區域S、S。中央區域M位於尿布100之寬度方向(物品寬度方向)Ya之中央部，一對側部區域S、S形成於中央區域M之沿第2方向Y之兩側緣之外側。具有以互不相同之圖案形成之凸部4之中央區域M及其兩側之一對側部區域S、S於尿布100之長度方向Xa上，較佳為至少形成於胯下部C，較佳為自胯下部C跨及至腹側部A及背側部B中之任一者或兩者而形成、或跨及吸收體14之全長，更佳為跨及尿布100之全長。 於圖4中，示有將複合片材10之中央區域M之一部分放大而表示之立體圖，於圖5中，示有將複合片材10之側部區域S之一部分放大而表示之立體圖。側部區域S形成於相對於沿尿布100之長度方向Xa之中央線(未圖示)左右對稱之位置，於側部區域S各者，以圖5所示之圖案形成有凹凸。 如圖4及圖5所示，複合片材10於中央區域M及側部區域S之任一者，均為經積層之第1片材1及第2片材2藉由壓紋加工局部接合而形成有複數個接合部，且經積層之第1片材及第2片材於複數個接合部相互接合。而且，於中央區域M及側部區域S之任一者，均為第1片材1於上述接合部以外之部位向遠離第2片材2之方向突出，而形成有向穿著者之肌膚側突出之凸部。複合片材10於中央區域M及側部區域S之任一者，均為第2片材2側之面大致平坦，且於第1片材1側形成有起伏較大之凹凸。 第1片材1及第2片材2由片材材料構成。作為片材材料，例如可使用不織布、織布及針織布等纖維片材、或膜等，就肌膚觸感等觀點而言，較佳為使用纖維片材，尤佳為使用不織布。構成第1片材1及第2片材2之片材材料之種類既可相同，或亦可不同。 作為將不織布用作構成第1片材1及第2片材2之片材材料之情形時之不織布，例如可列舉熱風不織布、紡黏不織布、水刺不織布、熔噴不織布、樹脂黏合不織布、針刺不織布等。亦可使用將該等不織布組合2種以上而成之積層體、或將該等不織布與膜等組合而成之積層體。其等之中，較佳為使用熱風不織布或紡黏不織布。用作構成第1片材1及第2片材2之片材材料之不織布之基重較佳為10 g/m2
以上，更佳為15 g/m2
以上，又，較佳為40 g/m2
以下，更佳為35 g/m2
以下。不織布之基重較佳為10 g/m2
以上40 g/m2
以下，進而較佳為15 g/m2
以上35 g/m2
以下。 作為構成不織布之纖維，可使用包含各種熱塑性樹脂之纖維。作為熱塑性樹脂，可列舉聚乙烯或聚丙烯等聚烯烴、聚對苯二甲酸乙二酯等聚酯、尼龍6或尼龍66等聚醯胺、聚丙烯酸、聚甲基丙烯酸烷基酯、聚氯乙烯、聚偏二氯乙烯等。該等樹脂可單獨使用1種，或作為2種以上之摻合物而使用。又，可以芯鞘型或並列型等複合纖維之形態使用。 於複合片材10之中央區域M，如圖4所示，於第1方向X隔開固定距離而形成有複數條沿第2方向Y連續延伸之中央連續凸部40。於複合片材10之中央區域M，形成有第1接合部31及第2接合部32。 另一方面，於複合片材10之一對側部區域S、S，如圖5所示，第1片材1於第3接合部33以外之部位向遠離第2片材2之方向突出而形成之邊側第1凸部41'於俯視時形成為散點狀，且形成為沿第1方向X及第2方向Y之各者分散之狀態。 邊側第1凸部41'係以與中央區域M之中央連續凸部40、或構成該中央連續凸部40之中央第1凸部41及中央第2凸部42不同之圖案所形成。凸部之圖案不同之表現包括僅凸部之配置不同之情形、凸部之形態不同之情形、及該等兩者均不同之情形中之任一者。凸部之配置不同之態樣亦包括凸部間之距離不同之情形。又，凸部之形態不同之態樣亦包括凸部之俯視形狀不同之情形。 於本實施形態之複合片材10中，凸部之配置及形態於中央區域M與一對側部區域S、S不同。 又，於側部區域S之第3接合部33之各者，成為第1片材1及第2片材2中之一者或兩者之構成纖維之構成樹脂經熔融固化之狀態，又，於第3接合部33之各者，第1片材1及第2片材2與其他部分(接合部以外之部分)相比均高密度化。即，複合片材10之第3接合部33係第1片材1與第2片材2被一體地加熱及加壓而形成之熱熔合部，藉由一片材或兩片材之構成纖維之構成樹脂之熔融及其後之固化而將兩片材相互結合。 又，中央區域M之第1及第2接合部31、32亦同樣，成為第1片材1及第2片材2中之一者或兩者之構成纖維之構成樹脂經熔融固化之狀態，又，於第1及第2接合部31、32，第1片材1及第2片材2與其他部分(接合部以外之部分)相比均高密度化。即，複合片材10之第1及第2接合部31、32亦係第1片材1與第2片材2被一體地加熱及加壓而形成之熱熔合部，藉由一片材或兩片材之構成纖維之構成樹脂之熔融及其後之固化而將兩片材相互結合。 再者，於第1～第3接合部31、32及33之各者，分別較佳為第1片材1及第2片材2兩者熔融固化。又，關於中央區域M之第1及第2接合部31、32，亦可將第1片材1與第2片材2之間藉由熱熔合以外之接合手段、例如熱熔接著劑等接著劑而形成該等接合部。 又，側部區域S之第3接合部33為熱熔合部，並且第3接合部33中之一部分接合部33a具有貫通孔33c。如圖6所示，貫通孔33c於接合部33a，沿厚度方向貫通複合片材10。又，貫通孔33c形成於接合部33a之中央部，且於俯視複合片材10時之貫通孔33c之周圍，呈環狀存在有第1片材1及第2片材2中之一者或兩者熔融後固化之部分。 根據第1實施形態之尿布100，構成正面片材12之複合片材10於尿布100之胯下部C，具有凸部之圖案不同之中央區域M及一對側部區域S、S，又，形成於該一對側部區域S、S之第3接合部33之一部分係具有貫通孔33c之接合部33a，因此與胯下部C之形成於一對側部區域S、S之第3接合部33均不具有貫通孔33c之情形時相比，一對側部區域S、S易於沿尿布100之長度方向(物品長度方向)Xa折曲，從而於穿著尿布100時，配設有複合片材10之側部區域S之尿布100之兩側部部分易於沿穿著者之腿圍彎曲，而不易對穿著者之腿圍造成不適感。 又，由於將貫通孔33c形成於作為熱熔合部之第3接合部33，故而於由穿著者之左右之大腿部等對尿布100之胯下部C之兩側部施加自左右朝向中央方向之壓縮力時，第3接合部33之形狀及邊側第1凸部41'之立體形狀相對較穩定地得到維持。 藉此，第1實施形態之尿布100不易對穿著者之腿圍造成不適感，此外，正面片材12之邊側第1凸部41'之保形性優異，透氣性亦優異。再者，於本實施形態之複合片材10中，邊側第1凸部41'之形狀、大小及配置主要係由第3接合部33之形狀、大小及配置所決定。 對第1實施形態之尿布100之正面片材12中所使用之上述複合片材10進而進行說明。 於圖7中，示有圖3所示之複合片材10之中央區域M之放大俯視圖。圖8(a)～圖8(c)係圖7之Va-Va線剖視圖、Vb-Vb線剖視圖及Vc-Vc線剖視圖。 如圖3、圖4及圖7所示，於複合片材10之中央區域M，於第1方向X隔開固定距離而形成有複數條沿第2方向Y連續延伸之中央連續凸部40。藉由於胯下部C之中央區域M，於沿物品長度寬方向Xa之第1方向X配設複數條於沿物品寬度方向Ya之第2方向Y延伸之複數條中央連續凸部40，可使於使用過程中容易悶濕之排尿部附近之透氣性提高。 於第1實施形態中所使用之複合片材10中，在中央連續凸部40之各者，如圖7及圖8(a)所示，於第2方向Y交替配置之中央第1凸部41與高度較中央第1凸部41低之中央第2凸部42相互連結。於本說明書中，所謂凸部連結係指相鄰之2個凸部未被接合部隔開，而為一凸部之一部分形成另一凸部之一部分，且另一凸部之一部分形成一凸部之一部分。 構成中央連續凸部40之中央第1凸部41及中央第2凸部42較佳為至少於中央第1凸部41之背面側存在空洞，進而較佳為於各自之背面側存在空洞，且中央第1凸部41之背面之空洞與中央第2凸部42之背面之空洞連續，於中央連續凸部40之背面側形成有沿第2方向Y連續延伸之連續中空部40V。 如圖7所示，構成中央連續凸部40之中央第1凸部41及中央第2凸部42之俯視下之形狀均為大致圓形狀。又，中央第1凸部41及中央第2凸部42於第1方向X及第2方向Y中之任一方向之剖面均呈具有頂部之形狀。 如圖7所示，於複合片材10之中央區域M，於第1方向X交替形成有非壓紋區域N及壓紋區域E，該非壓紋區域N沿第2方向Y延伸，於第2方向Y連續且不具有接合部，該壓紋區域E沿第2方向Y延伸，且以規則之圖案形成有接合部。 於壓紋區域E，形成有第1接合部31及第2接合部32作為經積層之第1片材1及第2片材2藉由壓紋加工局部接合而形成之接合部。 於各個壓紋區域E，如圖7所示，第1接合部31與第2接合部32之第2方向Y上之配置位置不同。又，第1接合部31與第2接合部32之沿第2方向Y之長度L1、L2亦不同。第1接合部31之俯視形狀均為矩形，該矩形之各邊與第1方向X或第2方向Y一致。第2接合部32之俯視形狀為大致正方形，該正方形之各邊與第1方向X或第2方向Y一致。 形成為矩形之第1接合部31使其長邊與第1方向X一致，且沿第2方向Y隔開間隔而配置成一行。藉此，形成有沿第2方向Y之第1接合部行R1。第2接合部32使相互正交之2邊中之一邊與第2方向Y一致，另一邊與第1方向X一致，且沿第2方向Y隔開間隔而配置成一行。藉此，形成有沿第2方向Y之第2接合部行R2。 於各第1接合部行R1，第2方向Y上之第1接合部31之配置間隔固定。於各第2接合部行R2，第2方向Y上之第2接合部32之配置間隔具有2種間隔，交替具有間隔較寬之部分與間隔較窄之部分。於各第1接合部行R1，沿第2方向Y觀察時之第1接合部31之配置位置均相同。於各第2接合部行R2，沿第2方向Y觀察時之第2接合部32之配置位置亦均相同。 如圖7所示，各個壓紋區域E包含1個第1接合部行R1、及於第1方向X上位於其兩側之2個第2接合部行R2。 若著眼於構成第1接合部行R1之1個第1接合部31，則構成2個第2接合部行R2之共計4個第2接合部32以使各自之角部與該第1接合部31之4個角部對向之狀態近接配置於該第1接合部31之周圍。藉此，形成有包含1個第1接合部31及位於其周圍之4個第2接合部32之一組接合部群30。於各個壓紋區域E，沿第2方向Y隔開固定間隔而形成有複數個相同之接合部群30。 於複合片材10中，藉由以上述態樣形成有第1接合部31及第2接合部32，以及於製造複合片材10時自背面側按壓、或自正面側抽吸第1片材1之相當於非壓紋區域N之部分或相當於壓紋區域E之第1接合部31彼此間之部位之部分等，而於複合片材10之中央區域M形成有如圖7及圖8所示之俯視形狀及剖面形狀之包含中央第1凸部41之中央連續凸部40、及中央第3凸部43等。 第1實施形態中所使用之複合片材10之中央區域M之中央連續凸部40具有沿第2方向Y連續延伸並且於第2方向Y寬度規則地內縮之部分。詳細而言，如圖7所示，於隔著非壓紋區域N而對向之一對第1接合部31彼此間，形成有中央第1凸部41，於被包含隔著非壓紋區域N而對向之兩對第2接合部32之共計四個第2接合部32包圍之區域，形成有中央第2凸部42，關於沿第1方向X之方向之長度，中央第2凸部42之長度L42短於中央第1凸部41之長度L41。中央連續凸部40之包含該中央第2凸部42之部分成為與包含中央第1凸部41之部分相比寬度(第1方向X之長度)較窄之內縮部分。 第1實施形態中所使用之複合片材10之中央區域M之壓紋區域E上成為與夾著非壓紋區域N之兩側之中央連續凸部40相比高度較低之槽部5(參照圖4)，又，側部區域S之邊側第1凸部41'間成為凹部，更詳細而言，圖10所示之第3方向接合部行R5上及第4方向接合部行R6上成為槽狀之凹部5S(參照圖9)。而且，如圖9所示，於中央區域M與側部區域S之交界部，中央連續凸部40彼此間之槽部5與形成於側部區域S之凸部間之凹部5S連續。所謂連續表示槽部5內之空間與凹部5S內之空間於複合片材10之平面方向上連通。 藉此，槽部5成為導液路徑，而可將供給至胯下部C等之中央區域M上之尿等液體引導至側部區域S，亦可自側部區域S將該液體吸收至吸收體14，從而可促進尿等排泄物被吸收體14之全域均勻吸收。就提高液體之吸收性而防止漏液之方面而言，與中央連續凸部40彼此間之槽部5連續之凹部5S較佳為包含具有貫通孔33c之接合部33a上之空間。 又，如圖7及圖8(c)所示，第1實施形態中所使用之複合片材10於壓紋區域E內，具有周圍被環狀凹部包圍之非連續之中央第3凸部43。中央第3凸部43於第1方向X及第2方向Y中之任一方向之剖面均呈具有頂部之形狀。中央第3凸部43之高度低於中央第1凸部41。中央第3凸部43於各自之背面側具有空洞43V，但亦可不具有此種空洞43V。 如圖7所示，中央第3凸部43係沿第2方向Y隔開固定距離而直線性地呈行狀配置有複數個，從而構成有中央第3凸部行。中央第2凸部42亦係沿第2方向Y隔開固定距離而直線性地呈行狀配置有複數個，從而構成有中央第2凸部行。中央第2凸部42與中央第3凸部43形成於第2方向Y上之相同位置。更詳細而言，中央第2凸部42與中央第3凸部43係沿第1方向X交替地且呈直線狀配置。中央第3凸部43之第1方向X上之配置位置位於中央第1凸部41、41彼此間。所謂第1方向X上之配置位置係指無視第2方向Y之位置，而僅觀察第1方向X上之位置時之配置位置。進而，如圖7所示，若除中央第2凸部42及中央第3凸部43以外亦著眼於第4凸部44，則該等3種凸部係以中央第2凸部42、第4凸部44、中央第3凸部43、及第4凸部44之順序，沿第1方向X規則地且呈直線狀配置。 第4凸部44之上表面大致平坦。再者，第4凸部44如字面意思所示為「凸部」，但該第4凸部44之高度較構成中央連續凸部40之中央第1及第2凸部41、42中之任一者均相對低，且其高度較中央第3凸部43相對低，因此自該等凸部觀察相對性地成為凹部。 本實施形態中所使用之複合片材10之中央區域M於構成其之第1片材1，形成有上述中央第1凸部41、中央第2凸部42、中央第3凸部43及第4凸部44。第4凸部44之高度較中央第1凸部41、中央第2凸部42及中央第3凸部43中之任一者均低。 於圖10中，示有圖3所示之複合片材10之側部區域S之放大俯視圖。圖11係圖10中之Vd-Vd線剖視圖。圖6係圖10中之Ve-Ve線剖視圖。 如該等圖所示，複合片材10之側部區域S於第2方向Y具有複數行由複數個第3接合部33於第1方向X串聯而成之第1方向接合部行Rx，且於第1方向X具有複數行由複數個第3接合部33於第2方向Y串聯而成之第2方向接合部行Ry。 於複合片材10之側部區域S，於第2方向Y形成有複數行由第3接合部33沿第1方向X以相等間隔配置而成之第1方向接合部行Rx。於第2方向Y形成有複數行之第1方向接合部行Rx係於第2方向Y交替具有第1方向X上之第3接合部33之配置位置一致之相鄰2行、及第1方向X上之第3接合部33之配置位置與該2行不同之其他相鄰2行。 於複合片材10之側部區域S，於第1方向X形成有複數行由第3接合部33沿第2方向Y以2種間隔La、Lb規則地配置而成之第2方向接合部行Ry。更詳細而言，第2方向接合部行Ry具有第1間隔La、及較第1間隔La寬之第2間隔Lb作為第2方向Y上之第3接合部33彼此間之間隔，且第2方向接合部行Ry中之複數個第3接合部33係以於第2方向Y交替具有該等2種間隔之方式於第2方向Y間歇配置。 構成各個第2方向接合部行Ry之複數個第3接合部33之第1方向X上之長度及配置位置一致，且於在第1方向X上相鄰之第2方向接合部行Ry間形成有固定寬度W之間隙。又，於第1方向X形成有複數行之第2方向接合部行Ry每隔一行，第2方向Y上之第3接合部33之配置位置一致，而相鄰之第2方向接合部行Ry彼此之第2方向Y上之第3接合部33之配置位置互不相同。詳細而言，如圖10所示，於本實施形態中之複合片材10之側部區域S，於第1方向X交替形成有第2方向Y上之第3接合部33之配置位置互不相同之第2方向第1接合部行Ry1及第2方向第2接合部行Ry2作為第2方向接合部行Ry，關於第2方向Y上之第3接合部33之配置位置，第2方向第1接合部行Ry1及第2方向第2接合部行Ry2係於一者中之以第2間隔Lb相鄰之第3接合部33彼此間存在另一第2方向接合部行Ry中之以第1間隔La相鄰之一對第3接合部33。 而且，如圖10所示，於被包含在第2方向接合部行Ry中相鄰之2個第3接合部33、33之共計6個第3接合部33包圍之區域內，形成有上述邊側第1凸部41'。 於本實施形態之複合片材10中，於各個第2方向接合部行Ry，包含沿第2方向Y以第1間隔La近接配置之一對第3接合部33的接合部對34在第2方向Y以第1間隔La之2倍以上之間隔Lb間歇配置，邊側第1凸部41'形成於在第2方向Y上相鄰之接合部對34、34彼此間。接合部對34包含於第2方向接合部行Ry中以最窄之間隔La相鄰之一對第3接合部33。 於複合片材10中，藉由以上述態樣形成有第3接合部33，以及於製造複合片材10時自背面側按壓、或自正面側抽吸第1片材1之相當於被共計6個第3接合部33包圍之區域之部分等，而於複合片材10之側部區域S形成有多個如圖10及圖11所示之俯視形狀及剖面形狀之邊側第1凸部41'。 關於第1實施形態中之複合片材10之側部區域S，如圖10所示，上述第1方向接合部行Rx與上述第2方向接合部行Ry中之第2方向接合部行Ry包含具有貫通孔33c之接合部33a之比率最高之最大比率接合部行Rym。 藉由第2方向接合部行Ry包含最大比率接合部行Rym，而易於沿尿布100之寬度方向(物品寬度方向)折曲，從而於穿著尿布100時，配設有複合片材10之側部區域S之尿布100之兩側部部分易於沿穿著者之腿圍之彎曲形狀彎曲，對腿圍之服貼感提高，不易對穿著者之腿圍造成不適感。 此處，所謂「最大比率接合部行」係對自1片尿布之各側部區域S任意各切出2片之、第1方向之長度為20 mm、第2方向之長度為100 mm之矩形狀之測定片進行觀察，按照以下順序(1)～(3)予以決定。 (1)自第1方向接合部行Rx之中，選擇具有貫通孔33c之接合部33a之比率最高之接合部行，將該接合部行設定為第1方向最大比率接合部行Rxm。例如，如圖10所示，作為第1方向接合部行Rx，具有第1方向第1接合部行Rx1及第1方向第2接合部行Rx2，該第1方向第1接合部行Rx1係在第1方向X交替地具有不具有貫通孔之第3接合部33與具有貫通孔33c之第3接合部33a，且構成該接合部行之接合部之個數中具有貫通孔33c之接合部33a之比率(以下，亦稱為「帶孔接合部比率」)為50%，該第1方向第2接合部行Rx2係構成該接合部行之接合部之個數中全部為不具有貫通孔33c之接合部33，上述帶孔接合部比率為0%，於此情形時，上述帶孔接合部比率最高之第1方向第1接合部行Rx1成為第1方向最大比率接合部行Rxm。 (2)自第2方向接合部行Ry之中，選擇具有貫通孔33c之接合部33a之比率最高之接合部行，將該接合部行設定為第2方向最大比率接合部行Rym。例如，如圖10所示，作為第2方向接合部行Ry，具有第1第2方向第1接合部行Ry1、以及第2第2方向第1接合部行Ry1及第2方向第2接合部行Ry2，該第1第2方向第1接合部行Ry1係構成接合部行之接合部之個數中全部為具有貫通孔33c之接合部33a，帶孔接合部比率為100%，該第2第2方向第1接合部行Ry1及第2方向第2接合部行Ry2係構成接合部行之接合部之個數中全部為不具有貫通孔33c之接合部33，上述帶孔接合部比率為0%，於此情形時，上述帶孔接合部比率最高之第1第2方向第1接合部行Ry1成為第2方向最大比率接合部行Rym。於圖10所示之例中，於第1方向X每隔3行而配置之第1第2方向第1接合部行Ry1係第2方向最大比率接合部行Rym。 (3)對第1方向最大比率接合部行Rxm之帶孔接合部比率與第2方向最大比率接合部行Rym之帶孔接合部比率進行比較，將帶孔接合部比率更高者作為最大比率接合部行。於圖10所示之例中，第1方向最大比率接合部行Rxm之帶孔接合部比率為50%，相對於此，第2方向最大比率接合部行Rym之帶孔接合部比率為100%，因此帶孔接合部比率為100%之第2方向最大比率接合部行Rym成為最大比率接合部行。 又，如圖10所示，第1實施形態中之複合片材10之側部區域S於第1方向X週期性地具有第2方向最大比率接合部行Rym，該第2方向最大比率接合部行Rym於第1方向X上具有複數行之第2方向接合部行Ry中具有貫通孔33c之接合部33a之比率(上述帶孔接合部比率)最高。 若於第1方向X週期性地具有第2方向最大比率接合部行Rym，則易於沿尿布100之寬度方向(物品寬度方向)規則地折曲，從而於穿著尿布100時，配設有複合片材10之側部區域S之尿布100之兩側部部分沿穿著者之腿圍之彎曲形狀服貼感進而提高，更不易對穿著者之腿圍造成不適感。 「第2方向最大比率接合部行」係藉由上述順序(2)中所記載之方法而決定。 於圖10所示之例中，第2方向最大比率接合部行Rym於第1方向X上，每隔3行而配設，但亦可每隔1行、每隔2行、或每隔4行而配設。又，除帶孔接合部比率為100%及0%之第2方向接合部行Ry以外，亦可具有帶孔接合部比率超過0%且未達100%之第2方向接合部行Ry。 再者，第2方向最大比率接合部行Rym之帶孔接合部比率較佳為10%以上100%以下，更佳為15%以上100%以下。又，第2方向最大比率接合部行Rym與第2方向接合部行Ry中帶孔接合部比率最低之第2方向接合部行Ry之差較佳為5%點以上，更佳為10%點以上，又，較佳為100%點以下，更佳為95%點以下。 又，第1方向最大比率接合部行Rxm之帶孔接合部比率較佳為10%以上100%以下，更佳為15%以上95%以下。又，第1方向最大比率接合部行Rxm與第1方向接合部行Rx中帶孔接合部比率最低之第1方向接合部行Rx之差較佳為0%點以上，更佳為5%點以上，又，較佳為95%點以下，更佳為90%點以下。 又，第2方向最大比率接合部行Rym與第1方向最大比率接合部行Rxm之帶孔接合部比率之差較佳為5%點以上，更佳為10%點以上，又，較佳為90%點以下，更佳為80%點以下。 又，就使尿布100等吸收性物品柔軟，並抑制因應力而導致之邊側第1凸部41'之立體形狀之變形之觀點而言，於複合片材10之側部區域S，側部區域S內所包含之接合部33中具有貫通孔33c之接合部33a之比率較佳為5%以上，更佳為10%以上，進而較佳為15%以上，又，較佳為80%以下，更佳為75%以下，進而較佳為70%以下。 此處所謂之「比率(%)」係將自側部區域S各切出2片之、第1方向X之長度為20 mm、第2方向Y之長度為100 mm之矩形狀之測定片中所包含之具有貫通孔33c之接合部33a之個數除以該測定片中所包含之接合部之總數所得之數值轉換成百分比而求出。又，其為4個樣本之平均值。 對第1實施形態中之複合片材10之側部區域S之構成進而進行說明。 如圖3、圖5及圖10所示，於複合片材10之側部區域S，邊側第1凸部41'於俯視時呈散點狀、更詳細而言為錯位狀形成於複合片材10。邊側第1凸部41'被上述6個第3接合部33包圍。包圍邊側第1凸部41'之6個第3接合部33及6個第3接合部33中相互相鄰之第3接合部33間之部位於邊側第1凸部41'之中央部之周圍形成環狀之凹部，邊側第1凸部41'形成為沿複合片材10之平面方向分散之狀態。 更詳細而言，如圖10所示，於在俯視之複合片材10上假定相互平行之複數條第1假想直線L3、及於與第1假想直線L3之間具有角度θ(參照圖10)的相互平行之複數條第2假想直線L4時，邊側第1凸部41'位於第1假想直線L3與第2假想直線L4之各交點。 藉由將邊側第1凸部41'配置於格子之交點，沿第2方向Y配置之槽部5成為導液路徑，而可將供給至胯下部C等之中央區域M上之液體引導至側部區域S，呈格子狀配置於側部區域S之邊側第1凸部41'成為障壁而亦可促進向第1方向X之擴散，從而可進而促進尿等排泄物被吸收體14之全域均勻吸收。 第1假想直線L3與第2假想直線L4所成之角度θ(參照圖10)較佳為30°以上165°以下，進而較佳為45°以上150°以下。再者，於圖10所示之例中，第1假想直線L3及第2假想直線L4均相對於第1方向X及第2方向Y傾斜，但亦可使第1假想直線L3或第2假想直線L4中之任一者或兩者與第1方向X或第2方向Y平行。 於複合片材10之側部區域S，形成有由複數個邊側第1凸部41'以固定間隔沿第1假想直線L3串聯而成之複數條第3方向凸部行、及由複數個邊側第1凸部41'以固定間隔沿第2假想直線L4串聯而成之複數條第4方向凸部行。又，於相鄰之第3方向凸部行彼此間，形成有由複數個接合部對34以固定間隔串聯而成之第3方向接合部行R5，於相鄰之第4方向凸部行彼此間，形成有由複數個接合部對34以固定間隔串聯而成之第4方向接合部行R6。構成各個接合部對34之一對第3接合部間及於邊側第1凸部41'之周圍相互相鄰之接合部對34彼此間成為微小凸部44'，但微小凸部44'之高度係自第3接合部33之上表面略微突出之程度，通常，該高度H4'為邊側第1凸部41'之1/3以下。 因此，第3方向凸部行彼此間及第4方向凸部行彼此間成為空氣易於流通之通氣路徑，而可獲得優異之透氣性。 就使上述一種或兩種以上效果進一步確實地奏效之觀點而言，複合片材之凸部較佳為具有以下構成。 又，形成於中央區域M之高度最大之凸部、即構成中央連續凸部40或該中央連續凸部40之高度最高之部分之中央第1凸部41之高度H1[參照圖8(a)]較佳為0.5 mm以上，進而較佳為1.0 mm以上，又，較佳為5.0 mm以下，進而較佳為4.0 mm以下，又，較佳為0.5 mm以上5.0 mm以下，進而較佳為1.0 mm以上4.0 mm以下。 又，形成於側部區域S之高度最大之凸部即邊側第1凸部41'之高度H1'較佳為0.3 mm以上，進而較佳為0.6 mm以上，又，較佳為4.0 mm以下，進而較佳為3.0 mm以下，又，較佳為0.3 mm以上4.0 mm以下，進而較佳為0.6 mm以上3.0 mm以下。 所謂複合片材之凸部4之高度係指朝向吸收體14側之下表面至凸部4之頂部之高度。 又，第1接合部31較佳為沿第1方向X之長度為沿第2方向Y之長度之1.2倍以上，尤佳為1.5倍以上，又，較佳為5.0倍以下，尤佳為3.0倍以下，更具體而言，較佳為1.2倍以上5.0倍以下，尤佳為1.5倍以上3.0倍以下。 又，第1接合部31之沿第1方向X之長度較佳為第2接合部32之沿第1方向X之長度的1.2倍以上，尤佳為1.5倍以上，又，較佳為5.0倍以下，尤佳為3.0倍以下，更具體而言，較佳為1.2倍以上5.0倍以下，尤佳為1.5倍以上3.0倍以下。 第1接合部31之沿第1方向X之長度較佳為0.5 mm以上，尤佳為1.0 mm以上，又，較佳為10.0 mm以下，尤佳為5.0 mm以下，更具體而言，較佳為0.5 mm以上10.0 mm以下，尤佳為1.0 mm以上5.0 mm以下。 又，第2接合部32之沿第1方向X之長度較佳為0.1 mm以上5.0 mm以下，尤佳為0.2 mm以上3.0 mm以下，沿第2方向Y之長度較佳為0.1 mm以上5.0 mm以下，尤佳為0.5 mm以上3.0 mm以下。 又，第3接合部33之沿第1方向X之長度較佳為1.2 mm以上5.0 mm以下，尤佳為1.5 mm以上3.0 mm以下，沿第2方向Y之長度較佳為1.2 mm以上5.0 mm以下，尤佳為1.5 mm以上3.0 mm以下。 又，關於第3接合部33之第2方向接合部行Ry係第2方向Y上之第3接合部33間之間隔較大之部分之間隔La相對於間隔較窄之部分之第3接合部33間之間隔，較佳為2.0倍以上，尤佳為2.5倍以上，較佳為5.0倍以下，尤佳為4.0倍以下，較佳為2.0倍以上5.0倍以下，尤佳為2.5倍以上4.0倍以下。 各凸部41、41'、42、43、46之高度H1、H1'、H2、H3、H4如圖8及圖11所示，被定義為第2片材2之下表面至第1片材1之上表面之距離。又，高度H1、H1'、H2、H3、H4設定為使用數位顯微鏡(Keyence製造)觀察各凸部剖面而計測出第2片材2之下表面與凸部頂部之最短距離所獲得之值。 於製造上述構成之複合片材10時，以與日本專利特開2015-112343號公報中所記載之方法同樣之方式，將帶狀之第1片材1供給至周面互為嚙合形狀之第1輥與第2輥之間，使第1片材1變形為凹凸形狀之後，使第1片材1沿第1輥之周面部自嚙合部分移動，然後以與第1片材1重合之方式供給第2片材2，將兩片材1、2於加熱下夾壓於第1輥之凸部與加熱輥之間使之局部接合。而且，此時，使第1輥及第2輥之凹凸形狀、以及藉由第1輥與加熱輥而形成之接合部之圖案於第1片材之中央部與側部不同。又，藉由匣式加熱器等加熱機構，將第1輥或加熱輥之圓周方向或軸向之一部分加熱至高於其他部分之溫度，於被藉由該加熱而成為高溫之部分夾壓之部分，形成具有貫通孔之接合部。 亦可於第1輥之凸部之前端進而設置突出之銷，於被該銷強力加壓後之部分，形成接合部之貫通孔，以代替使第1輥或加熱輥之圓周方向或軸長方向之一部分之溫度高於其他部分之方法。再者，於將第1片材1嚙入至第1輥與第2輥之嚙合部使之變形為凹凸形狀時，較佳為將第1片材向輥內部方向抽吸，而促進第1片材1向凹凸形狀變形。 以上，基於本發明之較佳之實施形態對本發明進行了說明，但本發明並不受上述實施形態所限制。例如，作為吸收性物品之正面片材，上述複合片材10之中央區域M之縱長之第1接合部31及第2接合部32亦可使第2方向Y上之寬度相同，而於第2方向Y隔開間隔交替地且以相等間隔而配置。中央連續凸部40亦可為高度跨及第2方向Y之全長而固定。又，中央區域M之凸部亦可形成為散點狀。又，貫通孔33c之俯視形狀可採用橢圓形、長圓形、三角形、四角形、五角形、六角形、星形、心形、三角形等任意之形狀，而代替圓形。又，亦可於一個接合部33a形成有2個以上貫通孔，但形成於各個接合部之貫通孔較佳為1個以上30個以下。 又，本發明之吸收性物品亦可為短褲型(套穿型)之拋棄式尿布，又，亦可為短褲型或普通非短褲型之經期衛生棉，亦可為失禁護墊、衛生護墊等，而代替展開型之拋棄式尿布。 關於上述實施形態，本發明進而揭示以下吸收性物品。 ＜1＞

In addition, it can be used in the form of a composite fiber such as a core-sheath type or a side-by-side type. In the central area M of the composite sheet 10, as shown in FIG. 4, a plurality of central continuous convex portions 40 continuously extending in the second direction Y are formed at a fixed distance in the first direction X. In the central region M of the composite sheet 10, a first joining portion 31 and a second joining portion 32 are formed. On the other hand, in one of the pair of side regions S and S of the composite sheet 10, as shown in FIG. 5, the first sheet 1 protrudes away from the second sheet 2 at a location other than the third joining portion 33. The formed side first convex portion 41' is formed in a scatter shape in a plan view, and is formed in a state of being dispersed in each of the first direction X and the second direction Y. The side first convex portion 41 ′ is formed in a pattern different from the central continuous convex portion 40 of the central region M, or the central first convex portion 41 and the central second convex portion 42 constituting the central continuous convex portion 40. The manifestations of the different patterns of the convex portions include any one of a situation where only the arrangement of the convex portion is different, a situation where the shape of the convex portion is different, and a situation where both of them are different. The different configurations of the convex parts also include the different distances between the convex parts. In addition, the aspect in which the shape of the convex portion is different also includes the situation in which the shape of the convex portion is different in plan view. In the composite sheet 10 of the present embodiment, the arrangement and form of the convex portions are different in the central region M and the pair of side regions S and S. In addition, each of the third joining portions 33 in the side region S becomes a state in which the constituent resins of the constituent fibers of one or both of the first sheet 1 and the second sheet 2 are melted and solidified, and, In each of the third joining parts 33, the first sheet 1 and the second sheet 2 are denser than the other parts (parts other than the joining part). That is, the third joining portion 33 of the composite sheet 10 is a thermal fusion portion formed by heating and pressing the first sheet 1 and the second sheet 2 integrally. The melting of the constituent resin and subsequent solidification combine the two sheets with each other. In addition, the first and second joining parts 31 and 32 of the central region M are also in a state in which the constituent resins of one or both of the first sheet 1 and the second sheet 2 are melted and solidified. In addition, in the first and second joining parts 31 and 32, the first sheet 1 and the second sheet 2 are both higher in density than other parts (parts other than the joining part). That is, the first and second joining parts 31 and 32 of the composite sheet 10 are also heat fusion parts formed by the first sheet 1 and the second sheet 2 being heated and pressurized integrally. The melting and subsequent solidification of the constituent resins of the constituent fibers of the two sheets combine the two sheets with each other. Furthermore, in each of the first to third joining parts 31, 32, and 33, it is preferable that both the first sheet 1 and the second sheet 2 are melted and solidified, respectively. In addition, regarding the first and second joining parts 31 and 32 of the central region M, the first sheet 1 and the second sheet 2 may be joined by a joining means other than thermal fusion, such as a hot melt adhesive. Agent to form these joints. In addition, the third joining portion 33 of the side region S is a thermally fused portion, and a part of the joining portion 33a of the third joining portion 33 has a through hole 33c. As shown in FIG. 6, the through hole 33c penetrates the composite sheet 10 in the thickness direction in the junction part 33a. In addition, the through hole 33c is formed in the center of the joint 33a, and around the through hole 33c when the composite sheet 10 is viewed from above, one of the first sheet 1 and the second sheet 2 exists in a ring shape, or The solidified part after both melting. According to the diaper 100 of the first embodiment, the composite sheet 10 constituting the front sheet 12 is formed on the lower part C of the crotch of the diaper 100, and has a central area M with different patterns of convex portions and a pair of side areas S, S, and also forms A part of the third joining portion 33 in the pair of side regions S and S is a joining portion 33a having a through hole 33c, so it is connected to the third joining portion 33 formed in the pair of side regions S and S in the lower part of the crotch C Compared with the case where none of the through holes 33c are provided, the pair of side regions S and S are easier to bend along the longitudinal direction (article length direction) Xa of the diaper 100, so that the composite sheet 10 is provided when the diaper 100 is worn. The side parts of the diaper 100 in the side region S are easy to bend along the wearer's leg circumference, and it is not easy to cause discomfort to the wearer's leg circumference. In addition, since the through hole 33c is formed in the third joining portion 33 as the heat fusion portion, the wearer’s left and right thighs are applied to the both sides of the lower crotch C of the diaper 100 from left to right toward the center. Under the compression force, the shape of the third joining portion 33 and the three-dimensional shape of the side first convex portion 41' are maintained relatively stably. Thereby, the diaper 100 of the first embodiment is less likely to cause discomfort to the wearer's leg circumference. In addition, the side first convex portion 41' of the front sheet 12 has excellent shape retention and excellent air permeability. Furthermore, in the composite sheet 10 of this embodiment, the shape, size, and arrangement of the side first convex portion 41' are mainly determined by the shape, size, and arrangement of the third joining portion 33. The above-mentioned composite sheet 10 used in the surface sheet 12 of the diaper 100 of the first embodiment will be further described. In FIG. 7, an enlarged plan view of the central area M of the composite sheet 10 shown in FIG. 3 is shown. 8(a) to 8(c) are the Va-Va line cross-sectional view, the Vb-Vb line cross-sectional view, and the Vc-Vc line cross-sectional view of FIG. 7. As shown in FIGS. 3, 4 and 7, in the central region M of the composite sheet 10, a plurality of central continuous convex portions 40 continuously extending in the second direction Y are formed at a fixed distance in the first direction X. Due to the central area M of the lower part C of the crotch, a plurality of central continuous convex portions 40 extending in the second direction Y along the article width direction Ya are arranged in the first direction X along the article length width direction Xa. During use, the air permeability near the urinating part, which is prone to become stuffy and wet, is improved. In the composite sheet 10 used in the first embodiment, each of the continuous convex portions 40 in the center is, as shown in FIGS. 7 and 8(a), the first convex portions in the center alternately arranged in the second direction Y 41 and the central second convex portion 42 whose height is lower than that of the central first convex portion 41 are connected to each other. In this specification, the so-called convex part connection means that two adjacent convex parts are not separated by the joining part, but a part of one convex part forms a part of the other convex part, and a part of the other convex part forms a convex part. Part of the Ministry. The central first convex portion 41 and the central second convex portion 42 constituting the central continuous convex portion 40 preferably have a cavity at least on the back side of the central first convex portion 41, and more preferably have a cavity on the back side of each, and The cavity on the back of the central first convex portion 41 and the cavity on the back of the central second convex portion 42 are continuous, and a continuous hollow portion 40V continuously extending in the second direction Y is formed on the back side of the central continuous convex portion 40. As shown in FIG. 7, the shape of the center 1st convex part 41 and the center 2nd convex part 42 which comprise the center continuous convex part 40 is a substantially circular shape in plan view. In addition, the cross section of the central first convex portion 41 and the central second convex portion 42 in any one of the first direction X and the second direction Y has a shape having a top. As shown in FIG. 7, in the central area M of the composite sheet 10, non-embossed areas N and embossed areas E are alternately formed in the first direction X. The non-embossed areas N extend in the second direction Y and are formed in the second direction. The direction Y is continuous and has no joints, and the embossed area E extends along the second direction Y, and the joints are formed in a regular pattern. In the embossing area E, a first joining portion 31 and a second joining portion 32 are formed as a joining portion formed by partially joining the laminated first sheet 1 and the second sheet 2 by embossing. In each embossing area E, as shown in FIG. 7, the arrangement positions of the first joining portion 31 and the second joining portion 32 in the second direction Y are different. In addition, the lengths L1 and L2 of the first joining portion 31 and the second joining portion 32 along the second direction Y are also different. The planar shape of the first joining portion 31 is all a rectangle, and each side of the rectangle coincides with the first direction X or the second direction Y. The planar shape of the second joining portion 32 is a substantially square, and each side of the square coincides with the first direction X or the second direction Y. The first joining parts 31 formed in a rectangular shape have their long sides aligned with the first direction X, and are arranged in a row at intervals along the second direction Y. Thereby, the first joining portion row R1 along the second direction Y is formed. The second joining portion 32 is arranged such that one of the two sides orthogonal to each other coincides with the second direction Y, and the other side coincides with the first direction X, and is arranged in a row with an interval in the second direction Y. Thereby, the second joining portion row R2 along the second direction Y is formed. In each first joining part row R1, the arrangement interval of the first joining parts 31 in the second direction Y is constant. In each second joining portion row R2, the arrangement interval of the second joining portion 32 in the second direction Y has two kinds of intervals, and there are alternately a portion with a wider interval and a portion with a narrow interval. The arrangement position of the first joining part 31 when viewed in the second direction Y in each first joining part row R1 is the same. The arrangement positions of the second joining parts 32 when viewed in the second direction Y in each of the second joining part rows R2 are also the same. As shown in FIG. 7, each embossing area E includes one first joining portion row R1 and two second joining portion rows R2 located on both sides of the first joining portion row R1 in the first direction X. Focusing on one first joining part 31 constituting the first joining part row R1, a total of four second joining parts 32 of the two second joining part rows R2 are formed so that the corners of each of the first joining parts are connected to the first joining part. The four corners of 31 are arranged close to the periphery of the first joint 31 in a state where the four corners are facing each other. Thereby, a bonding part group 30 including one first bonding part 31 and four second bonding parts 32 located around it is formed. In each embossing area E, a plurality of the same joining part groups 30 are formed at a fixed interval along the second direction Y. In the composite sheet 10, the first joining portion 31 and the second joining portion 32 are formed in the above-mentioned manner, and the first sheet is pressed from the back side or sucked from the front side when the composite sheet 10 is manufactured. 1 corresponds to the part of the non-embossed area N or the part corresponding to the first joint 31 of the embossed area E, etc., and the central area M of the composite sheet 10 is formed as shown in FIGS. 7 and 8 The shown plan and cross-sectional shapes include the central continuous convex portion 40 of the central first convex portion 41, the central third convex portion 43, and the like. The central continuous convex portion 40 of the central region M of the composite sheet 10 used in the first embodiment has a portion that continuously extends in the second direction Y and is regularly contracted in width in the second direction Y.

N and the area surrounded by the four second joints 32 of the two pairs of opposing second joints 32 is formed with a central second convex part 42. Regarding the length along the first direction X, the central second convex part The length L42 of 42 is shorter than the length L41 of the central first convex portion 41. The portion of the central continuous convex portion 40 including the central second convex portion 42 becomes an indented portion having a narrower width (length in the first direction X) than the portion including the central first convex portion 41. The embossed area E of the central area M of the composite sheet 10 used in the first embodiment has grooves 5 (5) having a lower height than the central continuous protrusions 40 on both sides of the non-embossed area N. Referring to FIG. 4), the side first convex portions 41' of the side region S become concave portions. In more detail, the third direction joint portion row R5 and the fourth direction joint portion row R6 shown in FIG. The upper part becomes a groove-shaped recess 5S (refer to FIG. 9). Moreover, as shown in FIG. 9, at the boundary between the central area M and the side area S, the groove 5 between the central continuous protrusions 40 and the recess 5S formed between the protrusions of the side area S are continuous. The term “continuous” means that the space in the groove 5 and the space in the recess 5S are connected in the plane direction of the composite sheet 10. Thereby, the groove portion 5 becomes a liquid guiding path, and the liquid such as urine supplied to the central area M such as the lower part C of the crotch can be guided to the side area S, and the liquid can also be absorbed from the side area S to the absorber 14, thereby promoting the uniform absorption of excrement such as urine by the entire area of the absorber 14. In terms of improving liquid absorption and preventing liquid leakage, the concave portion 5S continuous with the groove portion 5 between the central continuous convex portions 40 preferably includes a space on the joint portion 33a having the through hole 33c.

The cross section of the central third convex portion 43 in any one of the first direction X and the second direction Y has a shape having a top. The height of the central third convex portion 43 is lower than that of the central first convex portion 41. The center third convex portion 43 has a cavity 43V on the back side of each, but it may not have such a cavity 43V. As shown in FIG. 7, a plurality of central third convex portions 43 are arranged linearly in a row with a fixed distance in the second direction Y, thereby constituting a central third convex portion row. A plurality of central second convex portions 42 are also arranged linearly in a row with a fixed distance along the second direction Y, thereby constituting a central second convex portion row. The central second convex portion 42 and the central third convex portion 43 are formed at the same position in the second direction Y. In more detail, the central second convex portions 42 and the central third convex portions 43 are alternately arranged in a linear shape along the first direction X. The arrangement position of the central third convex portion 43 in the first direction X is between the central first convex portions 41 and 41. The arrangement position in the first direction X refers to the arrangement position when the position in the second direction Y is ignored and only the position in the first direction X is observed. Furthermore, as shown in FIG. 7, if the fourth convex portion 44 is focused in addition to the central second convex portion 42 and the central third convex portion 43, the three types of convex portions are the central second convex portion 42 and the third convex portion. The order of the four convex portions 44, the central third convex portion 43, and the fourth convex portion 44 is regularly and linearly arranged along the first direction X. The upper surface of the fourth convex portion 44 is substantially flat. Furthermore, the fourth convex portion 44 is literally referred to as a "convex portion", but the height of the fourth convex portion 44 is higher than any of the central first and second convex portions 41, 42 constituting the central continuous convex portion 40 All of them are relatively low, and their height is relatively lower than that of the central third convex portion 43, and therefore relatively becomes a concave portion when viewed from these convex portions.
