Description
本發明係關於一種拋棄式尿布或吸收墊等吸收性物品、以及其製造裝置及製造方法。The present invention relates to an absorbent article such as a disposable diaper or an absorbent pad, and a manufacturing apparatus and a manufacturing method thereof.
吸收性物品藉由吸收體而吸收所排出之體液之大致全部。此處,尿布因係覆蓋腹部、臀部、及大腿部分者,故受到步行或翻身、嬰兒之爬行等各種身體、尤其腿之活動之影響。尤其,吸收體存在因身體之各種活動而歪扭、曲折、或斷裂之情形。如此一來,尿布對胯間之服貼性降低,而容易引起液體洩漏。因此,為了維持服貼性,而例如有如於專利文獻1所見般於吸收體之非肌膚抵接面側進行壓紋加工者。藉由對吸收體實施壓紋加工,而強化吸收體之剛性,從而對於因身體之活動施加之力,吸收體不易歪扭、且不易斷裂。 又,有如於專利文獻2及專利文獻3所見般,於吸收體之肌膚抵接面側實施相對於自尿布之前身片至後身片之方向傾斜地延伸之斜向格子狀之壓縮槽即壓紋加工者。 另一方面,一般於吸收性物品使用之吸收體係為了吸收及保持尿等液體,而主要以絨毛狀紙漿與高吸水性樹脂(Super Absorbent Polymer,以下稱為「SAP」)之混合體即吸收性芯體、及包覆該吸收性芯體之薄紙等芯體被覆材構成。 對於此種吸收性物品,就省資源化、物流成本之削減、於零售店等之收納效率之改善等觀點而言,需求被稱為超薄型等之輕量且小型者,而其逐漸成為主流。此種超薄型之吸收性物品可藉由將佔據吸收性物品之重量及體積之大部分之吸收體之重量降低、且設為小型而實現。即,以絨毛狀紙漿與SAP之混合體構成之吸收體芯體之薄型化可藉由提高SAP之相對含有率、或取代混合體而使用片狀之SAP來實現化。 但是,具有隨著提高吸收體中之SAP之含有率,而喪失吸收體本身之柔軟性之傾向從而吸收體之柔軟性受損,會導致吸收性物品之穿著時之不適感進一步增大。 針對於該問題,亦認為專利文獻1~3提出之技術較為有效,該技術係於吸收體之表面形成斜向格子形狀之壓縮槽,而追隨於對吸收體施加之扭曲力使吸收體自該等壓縮槽之部分容易地彎曲。其原因在於,藉由該等專利文獻之吸收體之構成,可保持吸收體之柔軟性,提高對穿著者之服貼性即對腿之前後運動或臀部之弧度之服貼性,而提昇對穿著者之肌膚之服貼性。進而,於專利文獻2及3中,藉由於肌膚抵接面側呈斜向格子形狀地形成有槽,而亦提昇於吸收體表面之液體之擴散性。此點亦可提高吸收體之利用效率,故亦可期待成本之降低。 壓縮槽係藉由使於表面壓紋圖案突起之壓紋輥於長條之吸收體片材上旋轉移動而形成。於製造尿布時,使壓紋輥於長條之吸收體片材等上旋轉而進行壓紋加工之後,將各種片材進行積層等之後切斷成所需大小。 [先前技術文獻] [專利文獻] [專利文獻1]日本專利特開2014-69002號公報 [專利文獻2]日本專利特開2015-16218號公報 [專利文獻3]日本專利特開2013-135824號公報The absorbent article absorbs substantially all of the discharged body fluid by the absorbent body. Here, since the diaper covers the abdomen, the buttocks, and the thighs, it is affected by various activities such as walking or turning over, crawling of the baby, and the like, particularly the legs. In particular, the absorbent body is awkward, tortuous, or broken due to various activities of the body. As a result, the diaper has a reduced conformability to the day, and is liable to cause liquid leakage. Therefore, in order to maintain the conformability, for example, as shown in Patent Document 1, the embossing process is performed on the non-skin contact surface side of the absorbent body. By embossing the absorbent body, the rigidity of the absorbent body is enhanced, so that the absorbent body is less likely to be twisted and less likely to be broken due to the force exerted by the activity of the body. Further, as seen in Patent Document 2 and Patent Document 3, the embossing is performed on the skin contact surface side of the absorbent body in an obliquely lattice-shaped compression groove extending obliquely from the front surface of the diaper to the back body piece. Processor. On the other hand, in general, an absorption system used for an absorbent article absorbs and retains a liquid such as urine, and is mainly a mixture of a fluffy pulp and a superabsorbent polymer (hereinafter referred to as "SAP"). A core body and a core covering material such as a tissue coated with the absorbent core are formed. In view of the reduction in resources, the reduction in the cost of logistics, and the improvement in the storage efficiency of retail stores, etc., the demand for such absorbent articles is called lightweight and small, such as ultra-thin, and gradually becomes Mainstream. Such an ultra-thin absorbent article can be realized by reducing the weight of the absorbent body which occupies most of the weight and volume of the absorbent article and making it small. That is, the thinning of the absorber core body composed of a mixture of fluff pulp and SAP can be achieved by increasing the relative content of SAP or replacing the mixture and using a sheet-shaped SAP. However, as the content of SAP in the absorbent body is increased, the flexibility of the absorbent body itself tends to be lost, and the softness of the absorbent body is impaired, which further causes an increase in discomfort during wearing of the absorbent article. In view of this problem, the techniques proposed in Patent Documents 1 to 3 are also considered to be effective, and the technique is to form a compression groove of an oblique lattice shape on the surface of the absorber, and to follow the twisting force applied to the absorber to cause the absorber to The portion of the compression groove is easily bent. The reason for this is that, by the constitution of the absorbent body of the patent documents, the flexibility of the absorbent body can be maintained, and the conformability to the wearer, that is, the compliance of the front and rear movements of the legs or the curvature of the buttocks can be improved, and the pair is improved. Wear the skin of the wearer's skin. Further, in Patent Documents 2 and 3, since the skin contact surface side is formed with a groove in an oblique lattice shape, the liquid diffusing property on the surface of the absorber is also enhanced. This also improves the utilization efficiency of the absorber, so that the cost can be expected to decrease. The compression groove is formed by rotationally moving an embossing roll having a surface embossed pattern projection on the elongated absorbent sheet. When the diaper is produced, the embossing roll is embossed by rotating the long absorbent sheet or the like, and then the various sheets are laminated or the like to be cut into a desired size.

[發明所欲解決之問題] 然而,如專利文獻1~3所記載之斜向格子形狀會於壓紋加工之過程中,於形成吸收體之格子之2條壓縮槽之交叉區域引起吸收體表面之緊繃,而有吸收體破裂之虞。又,於該交叉區域,因素材較吸收體表面之其他部分更集中,故吸收體變硬,而有肌膚觸感變差且柔軟性受損之問題。於吸收體之正面片材側之面配設槽之專利文獻2及3所揭示之構成雖與專利文獻1所揭示之構成相比具有於吸收體表面之液體之擴散性提昇之優點,但該問題更加顯著。 又,於設置壓縮槽之情形時,重要的是,即便施加因穿著者之體重形成之壓力,槽亦不會鬆弛。因此,本發明者試製了一種自配置於吸收體之肌膚抵接面側之正面片材(頂層片材)側將正面片材與吸收體一併壓縮而形成更不易鬆弛之壓縮槽之吸收性物品。於該情形時亦如上所述,藉由使壓紋輥於積層有正面片材之吸收體上旋轉而形成壓縮槽。以如此方式形成壓縮槽時,藉由壓紋輥之按壓,較吸收體位於更上層之正面片材等朝向槽陷入,而正面片材等容易成為高度緊繃之狀態。尤其,斜向格子狀等、具有於傾斜方向延伸之成分之壓紋圖案有格子點附近等、同時壓縮之地點間之距離變短(間隔變窄)之部分。若同時壓縮之地點間之距離變短,則自相鄰之壓縮地點雙方拉伸正面片材之力強烈地發揮作用,而容易成為正面片材高度緊繃之狀態。 雖壓縮槽本身因位於比未壓縮之部位低之位置,故而不與穿著者之肌膚直接接觸,但於格子之交點(格子點)附近、即格子之角附近,正面片材及吸收體被拉伸而以高度緊繃之狀態固定。因此,SAP抵接於正面片材,故正面片材之肌膚抵接面之格子之角附近成為高吸水性樹脂之凹凸不平感作為手感傳遞等、而成為比其他部分硬者。 進而,由於該格子之角附近位於比壓縮槽之底高之(接近穿著者之肌膚之)位置,故容易與穿著者之肌膚接觸,而對穿著者賦予肌膚觸感之堅硬或硬邦邦之觸覺。吸收性物品由於與胯間等細嫩之肌膚部分接觸,故尤其要求柔軟之肌膚觸感,因此格子之角部分較硬之情形不佳。 另一方面,正面片材由於為穿著者之肌膚抵接面,故為於穿著時等穿著者容易觀察之部位。若壓紋圖案為不太能感覺到規則性或設計性者,則美觀效果較低,視情形而有被穿著者誤認為製造不良導致之皺褶等之可能性。 本發明之目的在於提供一種吸收性物品,其係鑒於如以上之問題而成者,其目的係使吸收體之柔軟性或服貼性提昇。 本發明之另一目的之課題在於提供一種吸收性物品,其係將正面片材與吸收體一併壓縮而形成具有於傾斜方向延伸之成分之視覺上優美之壓紋圖案,並且即便於在傾斜方向延伸之成分交叉之交叉點附近亦對穿著者賦予柔軟之肌膚觸感。 本發明之課題在於提供一種吸收性物品,其係將正面片材與吸收體一併壓縮而形成具有於傾斜方向延伸之成分之壓紋圖案者,且即便於在傾斜方向延伸之成分交叉之部分亦對穿著者賦予柔軟之肌膚觸感。 [解決問題之技術手段] 本發明之第1形態係一種吸收性物品,其特徵在於:其具備透液性之正面片材、不透液性之背面片材、及配置於上述正面片材與上述背面片材之間之吸收體,且 於上述吸收體之上述正面片材側之面具有薄化部,該薄化部形成為,對於由與第1方向平行地延伸之第1直線之群、及與和第1方向交叉之第2方向平行地延伸之第2直線之群界定之格子,沿上述格子之格子線設置,且具有較上述正面片材側之上述吸收體之面更為凹陷之部分; 上述薄化部係於包含上述格子線之交叉點及其周邊之交叉區域設有邊界。 本發明之基本概念係藉由該形態表現。藉此,提供一種藉由複數個薄化部交叉之區域附近之剛性不易變高而提昇吸收體之柔軟性,且提昇服貼性之吸收性物品。 本發明之基本概念係於如下般之各實施形態展開。即: ·交叉區域壓縮成自正面片材側之面起之深度淺於薄化部之上述凹陷部分之第1實施形態; ·交叉區域包括包含交叉點之中央區域與其外側之區域,且其外側區域壓縮成自正面片材側之面起之深度淺於薄化部之上述凹陷部分、深於中央區域之第2實施形態; ·交叉區域包括包含交叉點之中央區域與其外側之外側區域,且中央區域壓縮成自正面片材側之面起之深度深於外側區域之第3實施形態; ·交叉區域為非壓縮區域之第4實施形態;及 ·交叉區域以自正面片材側之面起之深度淺於薄化部之上述凹陷部分、且於對應之吸收體之上述背面片材側之面產生***部之方式被按壓之第5實施形態。 又,本發明之另一形態在於一種製造裝置,其係製造如第5實施形態之吸收性物品者,且具備: 第1旋轉構件,其具有形成有凸部之外周面部,且構成為藉由上述凸部按壓上述吸收體之上述正面片材側,上述凸部包含:以於上述吸收體之上述正面片材側,形成沿第1方向延伸之第1凹部之方式構成之第1凸部、及以相對於上述第1凹部以交叉狀態形成沿與上述第1方向不同之第2方向延伸之第2凹部之方式構成之第2凸部;及 第2旋轉構件,其具有形成有凹陷部之外周面部,且構成為藉由與上述第1旋轉構件一同旋轉,夾持上述吸收體,而抵接於上述吸收體之上述背面片材側,上述凹陷部配置於對應於上述第1凸部與上述第2凸部交叉之區域之位置。 進而,本發明之又一形態亦在於一種製造方法,其係製造具備透液性之正面片材、不透液性之背面片材、及配置於上述正面片材與上述背面片材之間之吸收體之吸收性物品者,且具備如下步驟: 以於上述吸收體之上述正面片材側,形成沿上述第1方向延伸之第1凹部、及相對於上述第1凹部以交叉狀態沿與上述第1方向不同之第2方向延伸之第2凹部之方式,按壓上述吸收體之上述正面片材側;及 與上述按壓之步驟同時,以於對應於上述第1凹部與上述第2凹部交叉之區域的上述吸收體之上述背面片材側形成***部之方式,使上述吸收體之上述背面片材側變形;且 該製造方法係應用於第5實施形態之吸收性物品之製造者。[Problems to be Solved by the Invention] However, the oblique lattice shape described in Patent Documents 1 to 3 causes the surface of the absorbent body at the intersection of the two compression grooves forming the lattice of the absorbent body during the embossing process. Tight, and there is a rupture of the absorber. Further, in the intersection region, the factor material is more concentrated than the other portions of the surface of the absorber, so that the absorber becomes hard and the skin feels poor and the softness is impaired. The structures disclosed in Patent Documents 2 and 3 in which the grooves are disposed on the surface of the front surface of the absorbent body have an advantage of improving the diffusibility of the liquid on the surface of the absorbent body as compared with the configuration disclosed in Patent Document 1. The problem is even more pronounced. Further, in the case where the compression groove is provided, it is important that the groove does not slack even if a pressure due to the weight of the wearer is applied. Therefore, the inventors of the present invention have experimentally produced a surface of the front sheet (top sheet) disposed on the side of the skin contact surface of the absorbent body, and the front sheet and the absorbent body are compressed together to form an absorbent groove which is less likely to be loosened. article. Also in this case, as described above, the compression groove is formed by rotating the embossing roll on the absorbent body in which the front sheet is laminated. When the compression groove is formed in this manner, the front sheet or the like which is located above the upper layer is caught in the groove by the pressing of the embossing roll, and the front sheet or the like is likely to be highly tight. In particular, the embossed pattern having a component extending in the oblique direction, such as an oblique lattice shape, has a portion in the vicinity of the lattice point or the like, and the distance between the places where the compression is performed is shortened (the interval is narrowed). When the distance between the places to be compressed at the same time becomes short, the force for stretching the front sheet from both adjacent compression points strongly acts, and it is easy to become a state in which the front sheet is highly tight. Although the compression groove itself is located at a position lower than the uncompressed portion, it does not directly contact the wearer's skin, but the front sheet and the absorbent body are pulled near the intersection of the lattice (lattice point), that is, near the corner of the lattice. Stretched and fixed in a state of high tension. Therefore, since the SAP is in contact with the front sheet, the unevenness of the superabsorbent resin in the vicinity of the corner of the lattice contact surface of the front sheet is transmitted as a feeling of the hand, and is harder than other parts. Further, since the corner of the lattice is located higher than the bottom of the compression groove (close to the skin of the wearer), it is easy to come into contact with the wearer's skin, and the wearer gives the touch of the skin a hard or hard touch. Since the absorbent article is in contact with the delicate skin portion such as the daytime, it is particularly required to have a soft touch, so that the corner portion of the lattice is hard. On the other hand, since the front sheet is a contact surface of the wearer's skin, it is a part that the wearer can easily observe when wearing. If the embossed pattern is less likely to feel regular or design, the aesthetic effect is low, and depending on the situation, there is a possibility that the wearer mistakenly believes that wrinkles or the like are caused by manufacturing defects. It is an object of the present invention to provide an absorbent article which is based on the above problems and which aims to improve the softness or conformability of the absorbent body. Another object of the present invention is to provide an absorbent article which is formed by compressing a front sheet and an absorbent body to form a visually beautiful embossed pattern having a component extending in an oblique direction, and even if inclined The vicinity of the intersection where the components of the direction extend intersect also impart a soft touch to the wearer. An object of the present invention is to provide an absorbent article which is obtained by compressing a front sheet and an absorbent body to form an embossed pattern having a component extending in an oblique direction, and even a portion intersecting in a direction extending in an oblique direction It also gives the wearer a soft touch. [Means for Solving the Problems] The first aspect of the present invention provides an absorbent article comprising: a liquid-permeable front sheet; a liquid-impermeable back sheet; and the front sheet and the surface sheet. The absorber between the back sheets has a thinned portion on a surface of the absorber on the side of the front sheet, and the thinned portion is formed as a group of first straight lines extending in parallel with the first direction And a lattice defined by the group of the second straight lines extending in parallel with the second direction intersecting the first direction, disposed along the lattice line of the lattice, and having a depression more than the surface of the absorber on the front sheet side The thinned portion is provided with a boundary at an intersection including the intersection of the lattice lines and the periphery thereof. The basic concept of the invention is manifested by this form. Thereby, an absorbent article in which the rigidity of the vicinity of the region where the plurality of thinned portions intersect is not easily increased, the flexibility of the absorbent body is improved, and the conformability is improved. The basic concept of the present invention is developed in the following embodiments. That is, the first embodiment in which the intersection region is compressed to have a depth from the surface on the front sheet side that is shallower than the recessed portion of the thinned portion; the intersection region includes a central region including the intersection and an outer region thereof, and the outer portion thereof The second embodiment in which the region is compressed from the surface on the front sheet side to the depth of the thinned portion and deeper than the central portion; the intersection region includes a central region including the intersection and an outer region on the outer side thereof, and The third embodiment in which the central region is compressed to a depth from the surface on the front sheet side is deeper than the outer region; the fourth embodiment in which the intersection region is an uncompressed region; and the intersection region is from the surface on the front sheet side The fifth embodiment in which the depth is shallower than the recessed portion of the thinned portion and the raised portion is formed on the surface of the corresponding back sheet side of the absorbent body. According to another aspect of the present invention, in a manufacturing apparatus, the absorbent article according to the fifth embodiment is provided, comprising: a first rotating member having a peripheral surface formed with a convex portion, and configured to The convex portion presses the side of the front sheet of the absorbent body, and the convex portion includes a first convex portion configured to form a first concave portion extending in the first direction on the side of the front sheet of the absorbent body, And a second convex portion configured to form a second concave portion extending in a second direction different from the first direction with respect to the first concave portion; and a second rotating member having a depressed portion The outer peripheral surface portion is configured to be rotatable together with the first rotating member, to sandwich the absorber, and to abut against the back sheet side of the absorber, and the recessed portion is disposed to correspond to the first protrusion and The position of the region where the second convex portion intersects. Furthermore, another aspect of the present invention provides a method for producing a liquid-permeable front sheet, a liquid-impermeable back sheet, and a surface sheet disposed between the front sheet and the back sheet. The absorbent article of the absorbent body includes the steps of: forming a first concave portion extending in the first direction on the side of the front sheet of the absorbent body, and intersecting the first concave portion with the first concave portion The second concave portion extending in the second direction different from the first direction is pressed against the front sheet side of the absorbent body; and the step of pressing is performed to intersect the first concave portion and the second concave portion In the region of the absorbent body, the embossed portion is formed on the back sheet side to deform the back sheet side of the absorbent body, and the manufacturing method is applied to the manufacturer of the absorbent article according to the fifth embodiment.

本實施形態之尿褲型布10具有:前身片區域10F、後身片區域10R、及連接前身片區域10F及後身片區域10R之***區域10C。又,形成有於穿著時以前身片區域10F與後身片區域10R包圍穿著者之腰之部分之腰圍開口部10W。同樣,形成有以前身片區域10F及後身片區域10R之下端部與***區域10C包圍穿著者之兩腿之自大腿根至大腿肚附近之區域之任一區域之左右一對腿圍開口部10L。 於穿著尿褲型尿布10時,前身片區域10F位於穿著者之腹側,後身片區域10R位於穿著者之背側。且,***區域10C覆蓋穿著者之***,而成為穿著者之腿分別通過左右一對腿圍開口部10L之樣式。因此,腿圍開口部10L成為位於穿著者之兩腿之自根部至大腿肚附近之任意位置。 尿褲型尿布10係以與***區域10C一併覆蓋前身片區域10F及後身片區域10R之方式設置覆蓋片11,且將覆蓋片11之左右兩側緣部相互接合而形成有閉合部10J。藉此,劃分形成腰圍開口部10W與左右一對腿圍開口部10L。 於本實施形態之尿褲型尿布10中,假設於尿褲型尿布10之寬度方向之中央或其附近自腹側朝向背側通過***區域10C延伸之假想線P。具體而言,假想線P係例如若以尿褲型尿布10之穿著時之腰側為上、***側為下,則沿尿布10之腹側表面且沿上下方向延伸,並且經由***區域10C,而於背側亦沿尿褲型尿布10之表面於上下方向延伸者。本實施形態之尿褲型尿布10係吸收體13沿假想線P變長者,其長度方向平行於假想線P。且,將相對於假想線P正交之方向設為寬度方向。再者,尿褲型尿布之長度方向與寬度方向之比率可根據穿著者之體型適當變更。 如圖2所示,於覆蓋片11之長度方向之左右兩側緣部之中央,分別形成有成為圖1之腿圍開口部10L之呈半圓弧狀之一對缺口部11A。於覆蓋片11之與穿著者之肌膚接觸之面,以遍及前身片區域10F、***區域10C及後身片區域10R之方式,配置有呈細長矩形之形狀之吸收體13。吸收體13與底層片材12接合。與吸收體13接合之底層片材12係以成為其長度方向為與假想線P大致平行之方向、且假想線P通過其寬度方向之中央或其附近之位置之方式接合於覆蓋片11上。於吸收體13之表面上,接合有與穿著者之肌膚接觸之透液性之頂層片材14。 於覆蓋片11,分別以伸長狀態接合有用於形成腿圍皺褶之橡膠線15、與用於形成腰部皺褶之橡膠線17。 又,於頂層片材14之左右兩側緣部,具備有形成立體皺褶之一對側部片材18。一對側部片材18係用於在穿著時沿吸收體13之兩側緣部立起而防止穿著者***之尿之側漏之不透液性之構件。於側部片材18之各者,以使其內側端緣部向吸收體13側回折並固持之形狀配置有作為立體皺褶伸縮材之橡膠線19,並於橡膠線19收縮時,朝向穿著者之肌膚抵接方向立起。立體皺褶可採用於先前之尿布使用之眾所周知之構成。例如,可藉由於撥水性片材之層間夾入伸展狀態之立體皺褶伸縮材並固定而形成。 圖3係表示將本實施形態之尿褲型尿布10破斷展開之分解狀態之立體投影圖。使用圖3對尿褲型尿布10之積層構造進行說明。 如圖3所示,尿褲型尿布10係自外側依序將覆蓋片11、不透液性之底層片材12、吸收體13、及頂層片材14依序重疊並接合。 形成有一對缺口部11A之覆蓋片11係以穿著者之肌膚側之內部覆蓋片11B及接合於內部覆蓋片11B之外側之外部覆蓋片11C形成。內部覆蓋片11B接合於底層片材12。吸收體13係配置於底層片材12與頂層片材14之間,且隔著吸收體13將頂層片材14接合於底層片材12。外部覆蓋片11C係為了獲得良好之手感而以較薄之不織布形成,且於內部覆蓋片11B與外部覆蓋片11C之間,分別以伸長狀態接合有橡膠線15及17。又,於頂層片材14之左右兩側緣部,具備有形成立體皺褶之一對側部片材18。一對側部片材18係用於在穿著時沿吸收體13之兩側緣部立起而防止穿著者***之尿之側漏之構件。於側部片材18之各者,以使其內側端緣部向吸收體13側回折並固持之形狀配置有橡膠線19作為立體皺褶伸縮材。 再者,亦可利用底層片材12、吸收體13及頂層片材14形成接合於內褲等而吸收液體之吸收性物品。 圖4係將本實施形態之尿褲型尿布10於圖2之IV-IV剖面線切斷之剖視圖。使用圖4對尿褲型尿布10之吸收體13之剖面形狀進行說明。 於頂層片材14之表面,藉由間斷之壓紋加工,將吸收體13及頂層片材14壓縮,而一體形成四邊形狀之複數個凹部。藉由將複數個凹部空出間隔排列,而形成發揮使尿等液體通過之槽之功能之薄化部401。薄化部401係自吸收體13之頂層片材14側之面朝向底層片材12側具有其深度者。將由形成於吸收體13之表面之薄化部401包圍之部分稱為變形抑制部402。關於變形抑制部402之細節於下文敍述。再者,薄化部401之上部之稜線表示於以剖面切斷時看到之非薄化部401之部分之輪廓線403。 其次,使用圖5及圖6對本實施形態之尿褲型尿布10之吸收體13進行說明。圖5係本實施形態之尿褲型尿布10之吸收體13之以頂層片材14側之面為上之俯視圖。使用圖5對吸收體13之表面形狀進行說明。 吸收體13係主要包含紙漿與SAP者。吸收體13係以遍及前身片區域10F、***區域10C及後身片區域10R之方式,呈細長之矩形之形狀。吸收體13於長度方向,劃分成前身片部分M1、***部分M2、後身片部分M3之三部分。再者,於***部分M2,亦可對照包圍穿著者兩腿之大腿肚部分之左右一對腿圍開口部10L,而形成呈圓弧狀之一對缺口部。吸收體13係以自***部分M2向前身片部分M1之方向為前(上)方向,以自***部分M2向後身片部分M3之方向為後(下)方向,以與前後方向(長度方向)正交之方向為左右方向(寬度方向)。又,吸收體13為矩形,但本發明之吸收體之形狀並不限於此。例如,吸收體之形狀包含將前後(上下)端之角切成圓形者、於前後(上下)延伸之橢圓形者、圓形者、前後(上下)左右之長度為同等程度之矩形者等各種形狀。 進而,於吸收體13,形成有呈斜向格子狀延伸之薄化部501。本實施形態係薄化部501自薄化部形成區域N1之一端朝向另一端呈斜向格子狀不連續地延伸者。且,作為以吸收體13之凹部502為中心壓縮後之結果形成之薄化部501,根據凹部502之間隔及深度等既可為間斷之情形,亦可為連續之情形,還可為兩者之混合。又,吸收體13係由未圖示之包芯材(薄紙)包覆。包芯材係親水性之較薄之片材。再者,於本實施形態中,雖使用由包芯材包覆之吸收體13,但本發明之吸收體亦可不由 包芯材包覆。此點在下述之其他實施形態中亦相同。 如圖5所示,於本實施形態中,於薄化部形成區域N1,藉由將複數個凹部502按特定間隔排列之圖案而形成有薄化部501。薄化部501係由自與為平行於吸收體13之長度方向之假想線P所示之方向(長度方向)正交的吸收體13之寬度方向(左右方向)之一上側向另一下側(圖5中之朝向紙面自右上側向左下側)傾斜延伸之第1方向之複數個第1薄化部(第1圖案)501a、與自另一上側向一下側(圖5中之朝向紙面自左上側向右下側)傾斜延伸之第2方向之複數個第2薄化部(第2圖案)501b構成。各第1薄化部501a係相互平行且按特定間隔配置。同樣,各第2薄化部501b係相互平行且按特定間隔配置。但,複數個薄化部501亦可不相互完全平行,又,相互之間隔亦可不固定。 於圖5中,複數個第1薄化部501a係相對於假想線P分別以相同角度傾斜,且按特定間隔配置。即,各第1薄化部501a平行且按特定間隔配置,但本發明並不限於此,亦包含薄化部之間隔不固定者、或各薄化部之傾斜角度不同者。關於第2薄化部501b亦相同。又,於吸收體13,第1薄化部501a及第2薄化部501b均形成有複數條,但只要為形成有於傾斜方向延伸之第1薄化部及第2薄化部者,則不限定薄化部之條數。雖較佳為兩者交叉,但本發明並不限於此,亦包含兩者不交叉者等。關於薄化部之作用之細節於下文敍述。 又,吸收體13於寬度方向之中央區域具有薄化部形成區域N1,且於其兩側具有薄化部非形成區域N2。吸收體13之寬度方向之兩側緣部為薄化部非形成區域N2,且於中央區域,薄化部形成區域N1自假想線P所示方向之一端朝向另一端呈帶狀地延伸。 圖6係本實施形態之尿褲型尿布10之基於圖5之VI-VI剖面線之局部剖視圖。 於薄化部501,藉由自吸收體13之頂層片材14側之面,以形成有特定之薄化部圖案之構件,將吸收體13視情形一面加熱一面壓縮而形成凹部502。且,各薄化部501之寬度及深度既可均一,亦可根據與相鄰之薄化部之間隔、薄化部之位置等而變化。又,設置於薄化部501之凹部502之側壁部分既可如圖6所示,為自吸收體表面斜向傾斜之V字狀,亦可為大致垂直延伸者。再者,凹部502之上部之稜線表示於以剖面切斷時看到之非凹部502之部分之輪廓線601。 藉由用於形成具有凹部502之薄化部501之上述壓縮,將薄化部凹部502及視情形將其附近(包含凹部間之間隙部分)比其他部分壓縮程度更大,而提高吸收體13之密度。壓縮程度最大之薄化部凹部502之壓縮率較佳為約4倍至7倍左右,且根據吸收體13之材質或所要吸收之液體,亦包含其他壓縮率之範圍。又,經壓縮之部分之吸收體密度與非壓縮部分相比成為2倍以上。吸收體密度主要為紙漿之密度。 如上所述,吸收體13中之薄化部501之凹部502係將吸收體13壓縮而形成者。因此,薄化部501之凹部502及視情形其附近相較於吸收體13之其他部分,吸收體13壓縮程度更大而變硬。 又,變形抑制部402因藉由凹部502按壓變形抑制部402內之吸收體外周,故不易變形。因此,即便相對於長度方向於傾斜方向產生拉伸力,吸收體13亦因凹部502之剛性而不易斜向歪扭出皺褶,且變形抑制部402亦不易變形,結果,抑制了關於傾斜方向之變形。因此,即便在腿之前後運動下,吸收體13亦不會大幅度歪扭而變形。因吸收體13不會歪扭,故可維持對胯間之服貼性,而不易引起體液洩漏。又,因藉由變形,亦可抑制吸收體13斷開,故可維持吸收性能。 再者,於本實施形態中,薄化部形成區域N1為自吸收體13之前身片部分M1遍及至後身片部分M3而延伸者,但本發明並不限於此。即,薄化部形成區域N1亦可為僅形成於***部分M2者。又,薄化部形成區域N1既可為僅形成於前身片部分M1、僅形成於後身片部分M3者,亦可為不形成於長度方向端部者。接近腰部分之部分因藉由腰部皺褶與皮膚密接,故可藉由使薄化部501之較硬之部分不抵接於皮膚,而提昇穿著感。 本實施形態之尿褲型尿布10係藉由以於吸收體13之表面積層頂層片材14之構成自頂層片材14之表面壓縮而形成具有凹部502之薄化部501者。即,頂層片材14以密接於薄化部501之狀態固定。如此,藉由將頂層片材14亦一併壓縮,而於頂層片材14亦形成變形抑制部402,從而抑制相對於步行時之活動而歪扭或斷裂。 於如上述所示,將積層於吸收體13之上之片材亦一併壓縮而形成凹部502之情形時,藉由該壓縮,吸收體13上之頂層片材14於凹部502及其附近之部分陷入至吸收體13側,而與吸收體13一體化。藉由此種牢固之吸收體13與各種片材之固定,即便在腿之前後運動下,亦抑制吸收體13之歪扭或偏移。 圖7係表示本實施形態之吸收體13上表面之薄化部501之一部分(圖5中虛線橢圓VII所包圍之吸收體13之薄化部501)之放大圖。 薄化部501可藉由將複數個凹部502空出間隔L1(即不連續地)排列而構成。於本實施形態中凹部502例如為四邊形狀,可藉由以同形狀之壓紋模壓縮吸收體13而形成。間隔L1為約2 mm。又,凹部之長度L2為約2.4 mm。又,凹部之寬度L3為約2 mm。L1、L2及L3分別以1 mm≦L1≦5 mm、1 mm≦L2≦50 mm、及1 mm≦L3≦5 mm之範圍為佳。再者,凹部502係模式性表示者,其數量或大小遵照該範圍。 凹部502空出間隔L1排列,但相鄰之凹部502間之間隙701較薄化部501所包圍之變形抑制部402更凹陷。即,伴隨形成凹部502時之壓縮,該間隙701部分之吸收體13被拉伸,而凹部502變得比變形抑制部402更凹陷。因此,凹部502與間隙701之間雖有高低差,但均比非壓縮部分低,而形成整體低於變形抑制部402之薄化部501。 於此種藉由間斷之壓紋加工構成之薄化部501中,壓縮率於凹部502之部分較佳為約4至7倍左右,但並非限定於該範圍,而係根據吸收體13之材質或所要吸收之液體,亦包含其他範圍。 如此,薄化部501可藉由間斷之壓紋加工構成。藉此,可抑制因腿之前後運動等所引起之吸收體之歪扭或變形。此外,於薄化部501之壓紋加工為間斷性之情形時,薄化部501本身亦變得容易彎曲,而更加服貼於身體,且容易追隨身體之活動,從而可抑制硬質感。 圖8係形成於本實施形態之吸收體13之上表面之薄化部501之說明圖,且係將圖5中虛線圓Q所包圍之薄化部形成區域N1內之1個格子形狀放大表示之圖。如圖8所示,具有如下構成:於藉由於交點A、B、C及D正交而形成斜向格子ABCDA之4條格子線AB、BC、CD、DA之各者設置薄化部501,且於各薄化部501,空出間隔排列有複數個凹部502。凹部502具有對吸收體13賦予凹凸形狀,而使吸收體13上之液體等擴散之作用。再者,圖8中之格子線AB、BC、CD及DA係模式性表示者。於本實施形態中,作為一例,凹部502為四邊形狀,可藉由以同形狀之壓紋模壓縮吸收體13而形成。又,較佳為,複數個凹部502之間隔為1 mm~5 mm、凹部502之長度為1 mm~50 mm、及凹部502之寬度為1 mm~5 mm之範圍。 如圖8所示,於線段AB上,間斷地排列有3個凹部502。位於線段AB上之中點附近之凹部502被壓縮得最深,線段AB上之交點A及交點B附近較凹部502壓縮得更淺。再者,凹部502之數量並非如本實施形態般限於3個。 圖9係形成於本實施形態之吸收體13之上表面之薄化部501之圖8之IX-IX剖面線之剖視圖。如圖9所示,薄化部501係以於線段AB上之自交點A至交點B之部分間斷地排列凹部502之方式構成。格子線AB及DA之交叉區域(交點A及其附近)901與格子線AB及BC之交叉區域(交點B及其附近)902壓縮得最淺,位於相鄰之2個交叉區域901及902之間之中間區域903之凹部502壓縮得最深。如此,格子線AB由壓縮為複數種深度之區域形成。換言之,於本實施形態中,薄化部501於交叉區域具有以自吸收體13之正面片材側之面起之深度淺於薄化部501之壓縮得最深之部分之方式被壓縮之邊界。再者,於本實施形態中,示出薄化部501間斷地形成有凹部502之例,但本發明並不限於此。例如,亦可為凹部502連續相連而形成薄化部501,且凹部502之深度自中間區域903之中央部朝向交叉區域901及902逐漸變淺。 於格子線AB間,於薄化部501之深度最深之凹部502之底部,間斷地形成有較凹部502之深度進而更深之層間接合壓縮部904。藉由形成層間接合壓縮部904,可藉由壓縮而使吸收體13與重疊於吸收體13之背面片材12成為一體之狀態。再者,層間接合壓縮部904既可形成1個,亦可形成複數個。又,凹部502之上部之稜線表示於以剖面切斷時看得到之非凹部502之部分之輪廓線905。 其次,使用圖8及圖9對本實施形態之吸收體13之表面形狀之加工方法之一例進行說明。 於在本實施形態之吸收體13之上表面形成斜向格子ABCDA之情形時,通常,利用壓紋加工之技術排列凹部502而構成格子線AB、BC、CD及DA,藉此形成斜向格子ABCDA。具體而言,例如,使成形輥於與其旋轉軸之延伸方向正交之方向旋轉而形成凹部502。於圖8中,使成形輥之旋轉軸之延伸方向與線段CA正交,而使成形輥與線段CA平行地自交點C朝向交點A旋轉(圖8之箭頭方向)。此處,於形成格子線AB及DA上之薄化部501之凹部之深度為固定之情形時,當成形輥靠近交點A附近之交叉區域901時,會有吸收體13表面之素材逐漸靠向交點A而引起緊繃之虞。 然而,關於本實施形態之形成薄化部501之部分之凹部502,由於交叉區域901之深度淺於中間區域903之凹部502之深度,故可防止吸收體13表面之素材靠向交點A。藉此,於中間區域903,由於一方面將吸收體13向背面片材12壓縮,一方面於交叉區域901內不會引起緊繃,故交點A附近之吸收體13之素材不會破裂,而可使吸收體13之柔軟性提昇。進而,由於可降低吸收體13之表面之硬度,故可提高穿著者之服貼性,且提昇穿著舒適感或肌膚觸感。 再者,薄化部之形狀並不限於本實施形態之形狀,可於延伸方向呈連續線地形成薄化部,或亦可就與延伸方向正交之剖面之寬度將其於中間區域擴大,而於交叉區域較窄地形成。又,既可將薄化部就其一部分以連續線形成,其餘間斷地形成,亦可使薄化部之與延伸方向正交之剖面面積根據其寬度、其深度之變化之組合而變化。 3.吸收性物品之第2實施形態 圖10係形成於可應用於圖1所示之尿褲型尿布之第2實施形態之吸收體13之上表面之薄化部1001之說明圖,且係將第1實施形態之圖5中虛線圓Q所包圍之薄化部形成區域N1內之1個格子形狀放大表示之圖。本實施形態之吸收體13之形狀與第1實施形態之吸收體13之形狀之不同點在於:於格子線AB形成連續之槽形狀之凹部1002,但其中,凹部1002之點bc間之部分形成薄化部1001,因此成為較位於交叉區域之凹部1002之點Ab間及點cB間之部分進而更深之凹部。 更具體而言,如圖10所示,於格子線AB上,位於交點A附近及交點B附近之凹部1002之點Aa間及點dB間之部分壓縮得最淺,分別與點Aa間及點dB間相鄰之凹部1002之點ab間部分及點cd間之部分壓縮得相對較深。且,位於格子線AB上之中央部之凹部1002之點bc間之部分(中間區域)壓縮得最深,而形成薄化部1001。換言之,於本實施形態中,將於格子線AB連續形成之凹部1002之中、點Ab間之區域及點cB間之區域規定為屬於交叉區域者,而交叉區域成為包含中間區域即點Aa間之區域及點dB間之區域、與各者之外側區域即點ab間之區域及點cd間之區域者。且,點bc間之部分成為本實施形態之薄化部1001。 圖11係本實施形態之吸收體13之圖10之XI-XI剖面線之剖視圖。如圖11所示,於自線段AB上之交點A至交點B連續地相連形成有凹部1002之本實施形態中,位於格子線AB及DA之交叉區域之中央區域(點Aa間)1101與格子線AB及BC之交叉區域之中央區域(點dB間)1102之凹部1002之部分壓縮得最淺。在位於相鄰之2個中央區域1101及1102之間之交叉區域之外側區域1103及1104(點ab間及點cd間)之凹部1002之部分壓縮得相對較深。且,在位於外側區域1103及1104之間之中間區域1105(點bc間)之凹部1002之部分成為被壓縮得最深之薄化部1001。如此,格子線AB由階段性地壓縮成複數種深度之區域形成。再者,於本實施形態中,示出薄化部1001具有一樣之深度而連續地形成之例,但本發明並不限於此。例如,亦可與上述之第1實施形態同樣,將凹陷部分間斷地排列而形成薄化部1001。又,點ab間之區域及點cd間之區域之階段性之深度亦可為3階段以上而非僅2階段。 於格子線AB間,於凹部1002之深度最深之中間區域1105之底部,間斷地形成有較中間區域1105之深度進而更深之層間接合壓縮部1106。藉由形成層間接合壓縮部1106,可藉由壓縮將吸收體13與重疊於吸收體13之背面片材12設為一體之狀態。再者,層間接合壓縮部1106既可形成1個,亦可形成複數個。又,凹部1002之上部之稜線表示於以剖面切斷時看到之非薄化部1001之部分之輪廓線1107。 本實施形態之吸收體13由於凹部1002之深度隨著自中間區域1105經由交叉區域之外側區域1103及1104朝向交叉區域之中央區域1101及1102階段性地變淺,故與第1實施形態同樣,可防止吸收體13表面之素材靠向交點A。藉此,於外側區域1103或中間區域1105(尤其是中間區域1105)中,由於一面將吸收體13向背面片材12壓縮,一面於中央區域1101內不會引起緊繃,故交點A附近之吸收體13之素材不會破裂,而可提昇吸收體13之柔軟性。進而,由於可降低吸收體13之表面之硬度,故可提高穿著者之服貼性,且提昇穿著舒適感或肌膚觸感。 此處,第1實施形態之吸收體13係輪廓線905與中間區域903之深度之差較小。相對於此,本實施形態之吸收體13係輪廓線1107與外側區域1103及1004之深度之差較大,故吸收體13容易沿著凹部1002彎曲。藉此,於本實施形態中可較實施形態1進一步提昇吸收體13之柔軟性。 圖12係形成於第2實施形態之變化例之吸收體13之上表面之薄化部1201之說明圖,且係將第1實施形態之圖5中虛線圓Q所包圍之薄化部形成區域N1內之1個格子形狀放大表示之圖。本實施形態之吸收體13之形狀與第2實施形態之吸收體13之形狀之不同點在於:於格子線AB形成連續之槽形狀之凹部1002,但其中,於點be間之薄化部1201,間斷地形成有2處凹陷得最深之凹部1202。 更具體而言,如圖12所示,於格子線AB上,交點A附近(點Aa間)及交點B附近(點fB間)即交叉區域之中央區域壓縮得最淺,於與點Aa間及點dB間相鄰之點af間較中央區域壓縮得相對更深。且,位於格子線AB上之點af間之中點之兩側之點bc間及點de間之凹部1202進而壓縮得最深。亦即,本實施形態之薄化部1201係間斷地設置有壓縮得最深之凹部1202者。 圖13係本實施形態之吸收體13之圖12之XIII-XIII剖面線之剖視圖。如圖13所示,於自線段AB上之交點A至交點B,位於格子線AB及DA之交叉區域之中央區域1301與格子線AB及BC之交叉區域之中央區域1302之點Aa間及點fB間之部分壓縮得最淺,位於相鄰之2個交叉區域之中央區域1301及1302間之交叉區域之外側區域1303及1305間之點ab間及點ef間之部分壓縮得相對較深。且,於位於外側區域1303及1305間之中間區域(點be間),一方面將相鄰於外側區域1304之點bc間之部分1306與相鄰於外側區域1305之點de間之部分1307壓縮為最深而形成2個凹部1202,另一方面,該等凹部1202間之點cd間之部分1304之深度較凹部1202相對更淺。如此,格子線AB被階段性地壓縮為複數種深度,且形成有複數個壓縮得最深之區域。再者,於本實施形態中,與第2實施形態同樣,示出於格子線上形成為連續相連之槽形狀之例,但本發明並不限於此。例如,亦可僅將最深之凹部1202間斷地排列而形成薄化部1201。又,階段性之深度亦可為3階段以上而非僅2階段。進而,最深之凹部1202之區域亦可為3個以上。 於格子線AB間,於凹部1202之底部,間斷地形成有較凹部1202之深度進而更深之層間接合壓縮部1308及1309。藉由形成層間接合壓縮部1308及1309,可藉由壓縮將吸收體13與重疊於吸收體13之背面片材12設為一體之狀態。再者,層間接合壓縮部1308及1309既可分別形成1個,亦可形成複數個。又,凹部1202之上部之稜線表示於以剖面切斷時看到之非薄化部1201之部分之輪廓線1310。 本實施形態之吸收體13由於格子線上之連續之凹部(槽)之深度隨著自中間區域經由交叉區域之外側區域1303及1305朝向交叉區域之中央區域1301及1302階段性地變淺,故與第1及第2實施形態同樣,可防止吸收體13表面之素材靠向交點A。藉此,於外側區域1303或薄化部之區域1307(尤其是區域1306及1307)中,由於一面將吸收體13向背面片材12壓縮,一面於中央區域1301不會引起緊繃,故交點A附近之吸收體13之素材不會破裂,而可提昇吸收體13之柔軟性。進而,由於可降低吸收體13之表面之硬度,故可提高穿著者之服貼性,且提昇穿著舒適感或肌膚觸感。 又,本實施形態之吸收體13因藉由於薄化部形成最深之凹部1202而薄化部成為容易彎曲之波狀,故可進一步提昇吸收體13之柔軟性。 本發明之吸收體亦可由親水性片材(包芯材等)包覆,並與親水性片材一併壓縮而形成凹部。又,亦可將吸收體、親水性片材及頂層片材自頂層片材之表面一併壓縮,而形成凹部。 又,凹部之形狀並不限於四邊形狀,可使用各種形狀。例如為圓、橢圓、正方形、三角形等。於該等任意形狀中,只要可於吸收體之表面形成薄化部即可。再者,於上述實施形態中,各凹部之寬度或深度等數值係以於各凹部中其寬度或深度成為最大值鄰域之中央附近為基準而測定者。如此,各凹部之寬度或深度等數值之原則為使用以各凹部之中心附近為基準而測定之值,但於各凹部之形狀複雜之情形時等,亦可將各凹部之其他部分作為寬度或深度等數值之測定基準。 本發明除上述之效果以外,亦可藉由利用斜向格子形狀使於吸收體表面之液體之擴散性提昇,而提高吸收體之利用效率,且可降低成本。再者,本發明之第1至第3實施形態之吸收體13之形態亦可相互組合。 4.吸收性物品之第3實施形態 一面參照圖14至圖21,一面對本發明之第3實施形態之吸收性物品進行詳細說明。本發明之第3實施形態亦可應用於第1實施形態之圖1所示之尿褲型尿布,於圖14至圖21中,對與第1或第2實施形態同樣地構成之部分,於對應部位標註同一符號。 圖14係自肌膚抵接面側觀察本實施形態之尿褲型尿布之俯視圖,對應於將圖1所示之尿布展開之狀態。於圖15表示圖14之XV-XV線破斷剖視圖,且於圖16表示圖14所示之尿褲型尿布之分解立體圖。又,圖17係自頂層片材14側觀察本實施形態之吸收體3013及頂層片材14所處之部分之局部俯視圖,圖18係表示圖17之斜向格子狀之壓紋圖案部分之模式性局部俯視圖。 本實施形態之吸收體3013基本上以與第1及第2實施形態同樣之材料構成。吸收體3013係以遍及前身片、***、後身片之方式,呈細長之形狀。且,於劃分成前身片部分M1、***部分M2、後身片部分M3之三部分時,於***部分M2,對照包圍兩腿之大腿肚部分之左右一對腿圍開口部10L,而形成有呈圓弧狀之一對缺口部3013a。再者,該缺口部3013a根據吸收體3013之大小亦可不形成。又,本實施形態之吸收體3013雖為中央部之寬度比前後端窄之沙漏型者,但本發明之吸收體之形狀並不限於此。若以自前身片部分向後身片部分為前後(上下)方向,且以與其正交之方向為左右方向,則包含例如將前後(上下)端之角切成圓形者、於前後(上下)延伸之橢圓形者、圓形者、前後(上下)左右之長度為同等程度之矩形者等各種形狀。此點於上述之第1及第2實施形態中設置缺口部之情形時亦相同。 並且,如圖17及圖18所示,尿布10具有藉由自頂層片材14表面朝向吸收體3013實施利用規則之壓紋加工進行之壓縮之薄化部形成區域(壓紋圖案形成區域)N1。於薄化部形成區域N1,藉由利用壓縮形成之複數個凹部3021、3023之排列,而形成有整體遠觀成為斜向格子狀之圖案之壓紋圖案。具體而言,具備位於格子之交點之凹部3023(以下,亦稱為「第1凹部」、「短凹部」)、與位於該等凹部3023之間之凹部3021(相當於本發明所規定之「薄化部」,具有連續之長槽形狀;於本實施形態中亦稱為「第2凹部」、「長凹部」)而形成。即,形成複數行將凹部3021與凹部3023交替排列成之壓縮行3022,並藉由該等複數行壓縮行3022之排列,而形成有分別斜向延伸之格子狀之壓紋圖案。雖於圖中未表示,但凹部3021係自頂層片材14表面將包芯材、吸收體3013一併壓縮而形成。 本實施形態之長凹部3021係在穿著尿布時相對於沿穿著者之身體之中心軸之假想線P傾斜者。具體而言,長凹部3021設置有相對於假想線P以特定角度α向第1方向即圖中右方向傾斜之右向長凹部3021a、與以特定角度β向第2方向即圖中左方向傾斜之左向長凹部3021b。且,如圖7所示,以交替地空出特定間隔L1形成行之方式配置有向同方向傾斜之長凹部3021、與短凹部3023。 如圖17所示,將右向長凹部3021a排列之行設為第1壓縮行3022a,將左向長凹部3021b排列之行設為第2壓縮行3022b。該等壓縮行3022係成為相對於假想線P以與長凹部3021之傾斜角度相同角度傾斜之直線狀者。進而,複數行第1壓縮行3022a係相互空出間隔S1平行地配置。又,複數行第2壓縮行3022b係相互空出間隔S2平行地配置。且,以短凹部3023位於第1壓縮行3022a與第2壓縮行3022b之交點之方式,決定各行3022之間隔S1、S2、及凹部3021、3023之排列之間隔L1。如此,藉由配置複數行第1壓縮行3022a與第2壓縮行3022b,而形成短凹部3023位於交點之斜向格子狀之壓紋圖案。於本實施形態中,間隔S1及S2雖設為相同值,但兩者亦可為不同值。 且,如自圖17及圖18可理解般,格子之一格(方格)為以下之構成。四邊以各長凹部3021形成,且4個頂點以短凹部3023形成。此處,長凹部21之長度短於先前之間隔S1、S2。如圖17所示,於格子點,右向長凹部3021a與左向長凹部3021b不重疊。換言之,於本實施形態中,將該不重疊之區域規定為交叉區域,而交叉區域成為包含形成有短凹部3023之中央區域與其外側之隔開短凹部3023與長凹部3021之外側區域者。 再者,如圖17所示,壓紋圖案未形成於吸收體3013之兩端。因此,吸收體3013係壓縮部非形成區域(壓紋圖案非形成區域)N2位於壓縮部形成區域(壓紋圖案形成區域)N1之兩側者。其係為了防止體液沿著壓紋圖案而自腿圍開口部10L洩漏。 圖19係將圖18之壓縮行之交點附近放大之模式圖,圖20係表示基於圖19之XX-XX線之剖面之圖。圖21係表示基於圖19之XXI-XXI線之剖面之圖。 如圖19所示,以包圍長凹部3021、及短凹部3023之周圍之虛線所示之區域為準壓縮區域3024。即,為了形成長凹部3021、短凹部3023而將頂層片材14與吸收體3013較強程度地直接壓縮,藉此,長凹部3021、短凹部3023之周圍之頂層片材14及吸收體3013因被拉伸而被間接壓縮。將如此般藉由壓紋模較強程度地壓縮之區域即凹部之周圍之被輕度壓縮之區域稱為準壓縮區域3024。因此,吸收體3013等被壓縮之區域、即壓縮區域成為各凹部3021、3023、及其周圍之準壓縮區域3024。且,吸收體3013等中之該等壓縮區域以外之區域未被壓縮,而成為非壓縮區域。即,位於作為格子之交點之短凹部3023與長凹部3021之間之外側區域即交點附近部3026、格子之內部即主吸收區域3025為非壓縮區域。 如圖20及圖21所示,非壓縮區域即主吸收區域3025與交點附近部3026係吸收體3013等之厚度(高度)相同。另一方面,長凹部3021、短凹部3023係吸收體3013等被壓縮,而比非壓縮區域更凹陷。且,連接非壓縮區域與各凹部3021、3023且吸收體3013之厚度逐漸變化之部分為準壓縮區域3024。 其次,對各凹部之形狀進行具體說明。 如圖19及圖20所示,長凹部3021係由形成其外形之長凹部第1部3211、與間斷地配置於長凹部第1部3211內且較長凹部第1部3211進而更深地凹陷之圓狀之長凹部第2部3212構成。長凹部第1部3211係如圖7所示般,較格子之邊之長度S1、S2更短之長度U與寬度V之細長者。具體而言,為其兩端成為圓弧之形狀。且,於長凹部第1部3211之內部,相對於其長度方向中心軸,以特定間隔交錯之方式配置有圓形之長凹部第2部3212。長凹部第2部3212較長凹部第1部3211向吸收體之厚度方向更深地凹陷。 如圖20所示,於長凹部3021中,長凹部第2部3212位於最深地點,長凹部第1部3211位於自長凹部第2部3212之底部稍微上升之位置。若將至長凹部3021之最深位置、即長凹部第2部3212之底之深度設為Q1,並將至長凹部第1部3211之底部之深度設為Q2,則自Q1減去Q2之差分即Q3成為至長凹部第2部3212之底之深度Q1之約3.5~15%左右。且,若將非壓縮區域之包含吸收體3013與頂層片材14之厚度設為Q4,則至長凹部第2部3212之底之深度Q1為厚度Q4之42.5%~97.5%左右。且,至長凹部第1部3211之底之深度Q2為厚度Q4之37.5%~95.0%左右。如此,本實施形態之長凹部3021係將吸收體3013壓縮至極深處而形成。且,成為具有2階段之深度之形狀。 另一方面,如圖9所示,位於格子之交點之短凹部3023係將吸收體3013等壓縮與長凹部第1部3211相同深度Q2而形成。 形成長凹部3021及短凹部3023之壓紋加工係於頂層片材14與吸收體3013之間介置有接著劑,並自頂層片材14表面將頂層片材14與吸收體3013一併壓縮者。長凹部3021、短凹部3023係藉由形成於壓紋輥之特定之模,自頂層片材14之表面將頂層片材14與吸收體3013一併壓縮而形成者。 且,於長凹部3021中,長凹部第2部3212為較小之圓,其面積較小。因此,於藉由壓紋輥進行之按壓中,壓力集中於長凹部第2部3212,將吸收體13與頂層片材14較強程度地壓縮。於該壓縮時,吸收體3013之紙漿纖維與頂層片材14之纖維牢固纏結,而以兩者成為一體之狀態接合。其次,雖於長凹部第1部3211亦於壓縮時施加相同按壓力,但面積較廣,相應地,壓力不似長凹部第2部3212般集中。因此,吸收體3013與頂層片材14之接合比長凹部第2部3212稍弱,但足以形成該凹部形狀。如此,於長凹部第2凹部3212中吸收體3013被較強程度地壓縮,且吸收體3013與頂層片材14牢固接合,藉此維持長凹部3021之形狀。例如,即便於穿著者坐下等,而對吸收體3013表面施加穿著者之體重引起之壓力時,該長凹部21亦不會鬆弛,而維持其形狀。並且,即便因腿之各種活動而將尿布10強力拉伸,頂層片材14與吸收體3013亦牢固接合,而長凹部3021維持其形狀。此處,亦可考慮不設為長凹部第1部3211與長凹部第2部3212之雙階段構造,而對長凹部3021整體施加較強之壓縮力而形成。即,於壓紋加工中,亦可考慮於對照長凹部第1部3211之大致橢圓狀之突起之內部,進而使用表面平緩之僅大致橢圓狀之突起之模壓縮,而非使對照長凹部第2部3212之圓形突起突出之模。然而,因以此種模無法製作壓力集中之部位,故若不整體地施加較強壓力,則無法製出正面片材與吸收體之纖維以較強程度地纏結之狀態接合之部位。作為結果,需要之按壓力變得非常強,而存在頂層片材14破裂之情形。又,於對整體以較弱按壓力進行之壓縮中,難以形成可承受穿著者之體重或各種活動之長凹部3021。於本實施形態中,於壓紋加工之模設置有對應於長凹部第2部3212之突起,而藉由局部較強程度地壓縮,製作將頂層片材14與吸收體3013牢固接合之部位,且於製造時防止頂層片材14破裂等不良產生。再者,根據頂層片材14之強度或壓縮量,亦可不使用此種雙階段之壓縮構造,而藉由間斷地排列點狀之凹部等之構成,形成壓縮行。 進而,設置於格子之交點之短凹部3023係如上所述,藉由該壓紋輥將吸收體3013與長凹部第1部3211相同程度地按壓而壓縮,藉此而形成。該按壓之強度係頂層片材14不破裂,而實現頂層片材14與吸收體3013之一體之接合之程度之強度。 如圖20、圖21所示,於吸收體3013中,長凹部第2部3212之底面部分為吸收體之密度最高之高密度部3013A。且,主吸收區域3025、交點附近部3026等非壓縮區域為吸收體之密度最低之低密度部3013D。且,長凹部第1部3211之底面部分及短凹部3023底部為中密度部3013B。準壓縮區域3024成為朝向非壓縮區域密度逐漸變低之密度變化部3013C。 此處,吸收體3013係如上述般主要包含SAP與紙漿者,且密度主要與紙漿纖維密度相關。因此,一方面,高密度部3013A為紙漿被壓縮而紙漿間之間隙較少之狀態,另一方面,低密度部3013D為紙漿間之間隙比高密度部3013A多之狀態。 此外,由於凹部3021、3023係將為合成纖維之頂層片材14與主要成分為紙漿之吸收體3013一併壓縮接合而形成,故凹部3021、3023之底面成為膜狀而被視為基本不吸收液體。因此,排出至凹部3021、3023上之體液於凹部3021、3023之側壁即密度變化部3013C被吸收,而向主吸收區域3025輸送。 如上所述,於本實施形態中,於形成壓縮行3022時,並非設為連續之凹部,而係間斷地排列凹部3021、3023而形成。尤其是,於該斜向格子之交點設置短凹部23,且下一長凹部3021位於與交點相隔之處所。關於如此設置間隔L1之理由於以下進行說明。 如上所述,斜向格子之壓縮行3022係藉由使於表面形成有對照各凹部3021、3023之模之壓紋輥一面旋轉、一面按壓而形成。如圖18所示,若壓紋輥一面旋轉,一面向箭頭W方向行進,則於相對於壓紋輥之行進方向W正交之方向(平行於旋轉軸之方向)排列之長凹部3021部分全部同時被按壓。於本實施形態中,雖以壓紋輥之圓周相當於吸收體3013之長度方向之長度之方式決定壓紋輥之尺寸,但並不限於此。 再者,於本實施形態中,壓紋輥之行進方向W係與壓紋輥之旋轉軸正交之方向,且於完成尿布10時,平行於成為先前之假想線P之方向。如上所述,於將頂層片材14與吸收體3013一併以壓紋輥壓縮之後,將所需之其他片材等進行積層等,並切斷成尿布10之尺寸。由於切斷係以遍及尿布10之前身片、***、後身片之長度進行,故可藉由將壓紋輥之行進方向W亦設為與假想線P平行,而形成相對於假想線P傾斜之斜向格子狀之壓紋圖案。 因此,右向長凹部3021a相對於行進方向W亦向右方向傾斜,且左向長凹部3021b向左方向傾斜。因此,隨著壓紋輥於行進方向W行進,朝向交叉部分3023相鄰之右向長凹部3021a與左向長凹部3021b間之距離逐漸變短。 此處,於形成凹部3021、3023之壓紋輥之按壓時,頂層片材14被引入至凹部3021、3023內。尤其是,長凹部3021因將右向長凹部3021a與左向長凹部3021b相鄰配置,故形成該等時自左右引入頂層片材14。亦即,於圖18中,於左右同時施加以箭頭A表示之引入力而拉伸頂層片材14。由於相鄰之右向凹部3021a與左向凹部3021b之距離越短,頂層片材14相對於引入力A之拉伸之餘裕部分越少,故頂層片材14逐漸成為高度緊繃狀態。 例如,若假設於製作相同大小之格子時,形成為不空出間隔L1而右向長凹部3021a與左向長凹部3021b於格子之交點接合之樣式,則於格子之角附近,右向長凹部3021a與左向長凹部3021b非常接近而配置。如此一來,於交點附近,吸收體3013自身之密度較高而為較硬狀態,此外,因接近之左右之長凹部3021a、3021b之引入力而使頂層片材14以高度緊繃之狀態與吸收體3013接觸。於交點附近之主吸收區域25中,吸收體3013中之SAP抵接於頂層片材14,而成為凹凸不平之手感。此點由於對穿著者之肌膚成為刺激,故而不佳。 因此,於本實施形態中,藉由不壓縮相鄰之長凹部3021間之距離未達特定距離T之交點附近部3026,而不將頂層片材14設為高度緊繃之狀態。即,將吸收體3013之壓縮及吸收體3013與頂層片材14之接合限定至主吸收區域3025內之頂層片材14能夠以具有餘裕之狀態維持之範圍。藉此,抑制起因於SAP之凹凸不平之手感及格子之角部分變硬。 亦即,如圖18、圖19所示,將右向長凹部3021a、左向長凹部3021b間之最短距離設為T,且僅於兩者間之距離成為T以上之部分形成有長凹部3021。因此,頂層片材14以鬆軟之狀態固定,而可避免較硬之手感。於圖中,距離T雖記為相對於行進方向W正交之方向,但關於平行於行進方向W之方向,亦由於產生因角部分變硬引起之問題,故較佳為同樣隔開固定距離以上,形成各長凹部3021。於本實施形態中,由於將右向長凹部3021a、左向長凹部3021b之長度設為相等,且將其形成間隔L1亦設為相等,故關於平行於行進方向W之方向亦同樣隔開距離T以上而形成各長凹部3021。 換言之,於決定壓紋圖案時,於平行於藉由第1壓縮行3022a與第2壓縮行3022b劃分形成之四邊形(格)之對角線之方向上,以相鄰之凹部間之距離成為T以上之方式,決定各長凹部3021之配置間隔。 再者,如上所述,由於引入力A係對相對於壓紋輥之行進方向W正交之方向強力作用,故可謂關於相對於壓紋輥之行進方向W平行之對角線,即便相鄰之凹部間之距離較T略短,其影響亦較小。 例如於本實施形態中吸收體之厚度為8 mm、第1凹部之深度Q2為6 mm之情形時,該T為7 mm左右。其亦根據吸收體3013中之SAP之量與紙漿纖維量之關係、或頂層片材14之厚度而變化。於本發明中重要之點在於,於使用具有斜向格子狀等斜向之成分之壓紋圖案時,於相鄰之凹部間之間隔變窄之部分不形成壓紋圖案。 另一方面,由於格子之交點自身並非接近而自左右雙方同時被按壓之處所,故不會強烈地拉伸頂層片材14。若考慮頂層片材14之拉緊,而於壓縮行3022中,採取過寬之未形成凹部之間隔,則有無法將壓縮行3022識別為行,而無法辨識格子之可能性。又,若長凹部3021間之間隔太寬,則吸收體3013難以發揮容易追隨身體之活動而斜向曲折之作用。因此,於不影響頂層片材14之拉緊之交點,設置凹部3023,而提高格子之辨識性,從而進一步提昇壓紋圖案之視覺效果。又,無需將格子方格之角設為較硬,而吸收體3013成為容易追隨身體之活動而曲折者。 如此,於本實施形態中,相鄰之凹部3021間之最短距離不會未達T。亦即,藉由設為將凹部3021隔開距離T以上配置之壓紋圖案、即格子之交點附近3026不進行壓紋加工之壓紋圖案,而防止肌膚抵接面之肌膚觸感變硬。且,因格子之角與主吸收區域3025同樣為鬆軟之狀態,故即便使用斜向格子狀之壓紋圖案,格子方格之角亦不會成為堅硬尖銳之手感,而可給予穿著者鬆軟之肌膚觸感。 又,於第1壓縮行3022a與第2壓縮行3022b之交點,藉由設置短凹部3023,而使格子之交點(方格之頂點)清晰,從而提昇美觀性、設計性。又,該斜向延伸之壓縮行3022不會被誤認為製造不良導致之皺褶、或不規則地排列之凹部等。又,於追隨身體之活動之吸收體3013之傾斜方向亦容易變形。 再者,於本實施形態中,壓紋加工雖係對使用壓紋輥者予以說明,但不限於該方法,亦可藉由對照尿布之大小之板狀之壓紋板以尿布之大小單位按壓壓紋者等。 其次對藉由壓紋加工形成之壓紋圖案之細節進行說明。 如圖18所示,本實施例之壓紋圖案係將右向長凹部3021a、與位於右向長凹部3021a之長度方向之前後之短凹部3023相互空出間隔L1而形成第1壓縮行3022a。左向長凹部3021b亦同樣地,與短凹部3023相互空出間隔L1而形成第2壓縮行3022b。該等中,第1壓縮行3022a係以間隔S1平行地配置複數行,第2壓縮行3022b係以間隔S2平行地配置複數行。並且,藉由該等第1壓縮行3022a與第2壓縮行3022b,如該圖所示般,形成遠觀成為斜向格子狀之壓紋圖案。 本實施形態之格子之1邊之長度S1及S2相等,為27.0 mm。格子之間隔較佳為13.0 mm以上54.0 mm以下。又,長凹部3021之長度方向之長度U為19.0 mm,且長度U較佳為格子之1邊之長度S1、S2之55%至85%。又,長凹部3021之寬度V為3.0 mm。寬度V較佳為2.0 mm以上、4.0 mm以下。又,短凹部3023之寬度V1與長凹部21之寬度V相同,或較其窄。本實施形態中之寬度V1為2.0 mm。寬度V1較佳為1.0 mm以上、4.0 mm以下。又,凹部3021、3023間之間隔L1為4.4 mm。間隔L1較佳為2.0 mm以上6.0 mm以下。藉由設為此種關係,除交點以外,相鄰之長凹部3021間之距離T未達6.0 mm之部位成為無凹部之狀態。 又,於本實施形態中,進行壓紋加工前之吸收體3013與頂層片材14之厚度為8.0 mm,如圖8所示,長凹部3021之最深部位之深度Q1為7.8 mm。且,其次深之部位之深度Q2為7.5 mm。且,非壓縮區域之厚度Q4為8.0 mm。 再者,壓紋加工前之包含吸收體3013及頂層片材14之厚度較佳為5.0 mm~20.0 mm。又,藉由凹部3021而壓縮之部分之最大深度Q1較佳為3.0 mm~8.0 mm。且,與其次深之部位之差Q3較佳為0.1 mm~0.5 mm。又,非壓縮區域之厚度(高度)Q4較佳為5.0 mm~20.0 mm。 藉由將各凹部3021、3023按此種深度及間隔形成,即便施加體重,亦可維持該薄化部,且於尿布之***部之肌膚抵接面,可維持柔軟之肌膚觸感。因此,藉由斜向格子狀之壓紋圖案,可抑制因腿之各種動作而使得尿布歪扭等變形,且使其肌膚觸感為柔軟者,可極力抑制對肌膚之刺激。 再者,於本實施形態中,長凹部3021雖藉由細長之大致橢圓形之長凹部第1部3211確定其外形,但本發明並不限於此,亦可間斷地配置複數個點或平行四邊形等之凹部而形成斜向格子狀之壓縮行。即,於本實施形態中,重要的是將未形成凹部之交點附近部3026僅設置特定之大小,以構成格子之各邊之長凹部21劃定之部分之凹部之形狀並不限定於本實施形態。排列上述之複數個點等亦可獲得同樣之效果。於該情形時,亦以與上述格子之方格之對角線平行之方向上之相鄰之凹部間之距離成為T以上之方式配置凹部。 又,於本實施形態中,亦可藉由縮短其長度方向之長度之2個以上之長凹部3021而非一個長凹部3021,而形成方格之一邊。又,長凹部第1部3211內之長凹部第2部3212之配置係以交錯之方式分配於寬度方向外側,但本發明並不限於此,亦可為於中央排列成一行之構成等任意者。又,長凹部第2部3212之形狀並不限於本實施形態所示之形狀,可採取四邊形、橢圓形、三角形等各種形狀。 又,於本實施形態中,短凹部設為4頂點尖銳之星狀,但本發明並不限於此,亦可為四邊形、圓等。即,只要為適於辨識格子之方格之頂點(角)之形狀,便可為任意者。 5.吸收性物品之第4實施形態 一面參照圖22至圖29,一面對本發明之吸收性物品之實施形態進行詳細說明。本發明之第4實施形態亦可應用於第1實施形態之圖1所示之尿褲型尿布,於圖22至圖29中,對與第1~第3實施形態同樣地構成之部分,於對應部位標註同一符號。 圖22係自肌膚抵接面側觀察本實施形態之尿褲型尿布之俯視圖,對應於將圖1所示之尿布展開之狀態。於圖23表示圖22之XXIII-XXIII線破斷剖視圖,且於圖24表示圖22所示之尿褲型尿布之分解立體圖。 又,圖25係自頂層片材14側觀察本實施形態之吸收體4013及頂層片材14所處之部分之局部俯視圖,圖26係表示圖25中之斜向格子狀之壓紋圖案部分之模式性局部俯視圖。 本實施形態之吸收體4013亦基本上以與第1及第2實施形態同樣之材料構成。又,吸收體4013之形狀係與第3實施形態之吸收體3013同樣,於劃分成前身片部分M1、***部分M2、後身片部分M3之三部分時,於***部分M2,對照包圍兩腿之大腿肚部分之左右一對腿圍開口部10L,而形成有呈圓弧狀之一對缺口部4013a。 且,如圖25及圖26所示,尿褲型尿布10具有自頂層片材14表面朝向吸收體4013實施藉由規則之壓紋加工進行之壓縮之壓縮部形成區域(壓紋圖案形成區域)N1。於壓縮部形成區域N1形成有藉由壓縮形成之複數個凹部4021,且形成有藉由該凹部之排列而遠觀成為斜向格子狀之圖案之複數行壓縮行4022。本實施形態之凹部4021係在穿著尿布時相對於沿穿著者之身體之中心軸之假想線P傾斜者。具體而言,凹部4021設置有相對於假想線P以特定角度α向第1方向即圖中右方向傾斜之長槽狀之右向凹部4021a、與以特定角度β向第2方向即圖中左方向傾斜之長槽狀之左向凹部4021b(以下,於無需區分該等時,以符號4021統一參照)。且,朝同方向傾斜之凹部4021係以空出特定間隔L1而形成行之方式配置,且形成有遠觀成為各者斜向延伸之格子狀之壓紋圖案。即,本實施形態之各凹部4021相當於本發明所規定之薄化部,且對應於第3實施形態之長凹部3021。雖於圖中未表示,但凹部4021係自頂層片材14表面將包芯材、吸收體13一併壓縮而形成。 再者,如圖25所示,壓紋圖案未形成於吸收體4013之兩端。因此,吸收體13係壓縮部非形成區域(壓紋圖案非形成區域)N2位於壓縮部形成區域(壓紋圖案形成區域)N1之兩側者。其係為了防止體液沿著壓紋圖案而自腿圍開口部10L洩漏。 如圖25所示,將右向凹部4021a排列之行設為第1壓縮行4022a,將左向凹部4021a排列之行設為第2壓縮行4022b(以下,於無需區分該等時,以符號4022統一參照)。該等壓縮行4022係成為相對於假想線P以與凹部4021之傾斜角度相同角度傾斜之直線狀者。複數行第1壓縮行4022a係相互空出間隔S1平行地配置。又,複數行第2壓縮行4022b係相互空出間隔S2平行地配置。如此,藉由配置複數行第1壓縮行4022a與第2壓縮行4022b,而形成有斜向格子狀之壓紋圖案。於本實施形態中,亦係間隔S1與S2設為相同值,但兩者亦可為不同值。 且,如自圖25可理解般,各凹部4021為可形成基於格子之方格之程度之長度。此處,凹部4021之長度短於先前之間隔S1、S2。即,如上所述,複數個凹部4021藉由空出特定間隔L1排列而形成壓縮行4022,但以凹部不位於該格子之交叉區域4023之方式,決定凹部之長度與格子之間隔。因此,右向凹部4021a與左向凹部4021a不重疊,成為藉由各凹部4021形成之斜向格子之交叉區域4023之頂層片材14與吸收體13未被壓縮之非壓縮區域。同樣,即便於藉由各凹部4021劃分形成之方格之內部區域即主吸收區域4025中,亦成為頂層片材14及吸收體4013未被壓縮之非壓縮區域。亦即,於本實施形態中,將分別相當於薄化部之右向凹部4021a與左向凹部4021a不重疊之區域規定為交叉區域4023,而該交叉區域4023成為非壓縮區域。 圖27係將圖26中之壓縮行之交點附近放大之模式圖,圖28係表示基於圖7之XXVIII-XXVIII線之剖面之圖。圖29係表示基於圖7之XXIX-XXIX線之剖面之圖。 如圖27及圖28所示,凹部4021係由形成其外形之第1凹部4211,與間斷地配置於第1凹部4211內且較第1凹部4211進而更深地凹陷之圓狀之第2凹部4212構成。第1凹部4211係如圖27所示般,為較格子之邊之長度S1、S2更短之長度U與寬度V之細長者。具體而言,為其兩端成為圓弧之形狀。並且,於第1凹部4211之內部,相對於其長度方向中心軸,圓形之第2凹部4212以特定間隔交錯之方式配置。第2凹部4212較第1凹部4211向吸收體4013之厚度方向更深凹陷。 如圖28所示,於凹部4021中,第2凹部4212位於最深地點,第1凹部4211位於自第2凹部4212之底部稍微上升之位置。將至凹部4021之最深位置、即第2凹部4212之底之深度設為Q1,並將至第1凹部4211之底部之深度設為Q2,自Q1減去Q2之差分即Q3、及非壓縮區域之包含吸收體4013與頂層片材14之厚度Q4之關係與第3實施形態相同。又,關於形成凹部4021之壓紋加工,亦可與第3實施形態同樣地進行,而可獲得與如第3實施形態般形成長凹部3021之情形同等之效果。 並且,於圖27中,以包圍凹部4021之周圍之虛線所表示之區域為準壓縮區域4024。即,為了形成凹部4021而將頂層片材14與吸收體4013較強程度地壓縮,藉此,凹部4021之周圍之頂層片材14及吸收體4013因被拉伸而壓縮。因此,與交叉區域4023或主吸收區域4025等非壓縮區域相比,準壓縮區域4024係吸收體13被間接地壓縮之區域。 如圖28所示,於吸收體4013中,第2凹部4212之底面部分為吸收體之密度最高之高密度部4013A。且,主吸收區域4025等非壓縮區域為吸收體密度最低之低密度部4013D。且,第1凹部4211之底面部分為中密度部4013B。準壓縮區域4024成為朝向非壓縮區域密度逐漸變低之密度變化部4013C。 此處,吸收體4013係如上述般主要包含SAP與紙漿者,且密度主要與紙漿纖維密度相關。因此,一方面,高密度部4013A為紙漿被壓縮而紙漿間之間隙較少之狀態,另一方面,低密度部4013D為紙漿間之間隙比高密度部4013A多之狀態。 此外,由於凹部4021係將為合成纖維之頂層片材14與主要成分為紙漿之吸收體4013一併壓縮接合而形成,故凹部4021之底面成為膜狀而被視為基本不吸收液體。因此,排出至凹部4021上之體液於凹部21之側壁即密度變化部4013C被吸收,而向主吸收區域4025輸送。 其次,於本實施形態中,於該斜向格子狀之壓紋圖案中之交叉區域4023,未設置凹部4021。亦即,作為薄化部之凹部4021於交叉區域4023具有邊界。如與上述之第3實施形態同樣,凹部4021係藉由使於表面形成有對照凹部4021之模之壓紋輥一面旋轉、一面按壓而形成。如圖26所示,若壓紋輥一面旋轉,一面向箭頭W方向行進,則於相對於壓紋輥之行進方向W正交之方向排列之凹部4021部分全部同時被按壓。於本實施形態中,雖亦以壓紋輥之圓周相當於吸收體4013之長度方向之長度之方式決定壓紋輥之尺寸,但並不限於此。 於本實施形態中,亦與第3實施形態同樣,壓紋輥之行進方向W於完成尿布10時,平行於成為先前之假想線P之方向。且,如關於第3實施形態於上文敍述般,於將頂層片材14與吸收體13一併以壓紋輥壓縮之後,將所需之其他片材等進行積層等,並切斷成尿布10之尺寸。由於切斷係以遍及尿布10之前身片、***、後身片之長度進行,故可藉由將壓紋輥之行進方向W亦設為與假想線P平行,而形成相對於假想線P傾斜之斜向格子狀之壓紋圖案。且,對於藉此形成之右向凹部4021a及左向凹部4021b間之間隔L1、最短距離T及相對於行進方向W之傾斜等,亦因與第3實施形態中關於長凹部3021所說明者相同,故省略說明。 於本實施形態中,相鄰之凹部4021間之最短距離亦不會未達T。亦即,藉由設為將凹部4021隔開距離T以上配置之壓紋圖案、即格子之交點附近不進行壓紋加工之壓紋圖案,而防止肌膚抵接面之肌膚觸感變硬。並且,因格子之角與主吸收區域4025同樣為鬆軟之狀態,故即便使用斜向格子狀之壓紋圖案,格子之角亦不會成為堅硬尖銳之手感,故可給予穿著者鬆軟之肌膚觸感。因此,第1壓縮行4022a與第2壓縮行4022b之交叉區域4023係藉由設為不設置凹部4021之非壓縮區域,而格子之角不會成為堅硬尖銳者,又,交叉區域4023之吸收體4013之厚度、高度成為與主吸收區域4025相同者。因此,即便形成斜向格子狀之壓紋圖案,尿布10之肌膚抵接面亦給予穿著者整體上鬆軟之肌膚觸感,且格子之角部分亦不會刺激皮膚。 再者,於本實施形態中,壓紋加工亦不限於使用壓紋輥進行者,亦可為藉由對照尿布之大小之板狀之壓紋板以尿布之大小單位按壓壓紋者等。又,關於藉由壓紋加工形成之壓紋圖案,亦與第3實施形態中關於長凹部3021或壓縮行3021a、3021b所說明者大致相同。 本實施形態中之格子之1邊之長度S1及S2相等,為27.0 mm。格子之間隔較佳為13.0 mm以上54.0 mm以下。又,並且,凹部4021之長度方向之長度U較佳為格子之1邊之長度S1、S2之約55%至約90%左右,於本實施形態中,長度U為19.0 mm。又,凹部4021之寬度V為3.0 mm。寬度V較佳為2.0 mm以上、4.0 mm以下。又,凹部4021間之間隔L1為8.8 mm。間隔L1較佳為4.0 mm以上12.0 mm以下。藉由設為此種關係,相鄰之凹部21間之距離T未達6.0 mm之部位成為無凹部之狀態。 又,於本實施形態中,進行壓紋加工前之吸收體4013與頂層片材14之厚度為8.0 mm,如圖28所示,凹部21之最深部位之深度Q1為7.8 mm。且,其次深之部位之深度Q2為7.5 mm。且,非壓縮區域之厚度Q4為8.0 mm。 再者,壓紋加工前之包含吸收體4013及頂層片材14之厚度、藉由凹部4021壓縮之部分之最大深度Q1、及與其次深之部位之差Q3亦可於與第3實施形態相同之範圍選擇,藉此可獲得同樣之效果。 又,關於本實施形態之凹部4021、第1凹部4211及第2凹部4212之形狀或配置,亦可如於第3實施形態中關於長凹部3021所說明般適當決定。 6.吸收性物品之第5實施形態以及其製造裝置及製造方法之實施形態 一面參照圖1至圖14,一面對本發明之吸收性物品之第5實施形態以及其製造裝置及製造方法進行詳細說明。 再者,於本實施形態中,「凹部」係參照作為包含藉由利用壓紋加工壓縮吸收體而形成之薄化部者。吸收體之中形成有凹部之部位與此外之部位相比成為高壓縮、高密度。又,於形成有該凹部之部位之密度與此外之部位相同之情形時,形成有該凹部之部位之厚度亦與此外之部位相同。 本實施形態之吸收性物品係構成為於形成於吸收體之頂層片材側之複數個凹部交叉之區域中,該區域之底層片材側***。亦即,本實施形態之凹部雖具有於格子一致之構成,但由在底層片材側具有***部且頂層片材側凹陷之交叉區域、與藉由該交叉區域確定邊界之薄化部構成者。藉由該構成,於複數個凹部交叉之區域附近剛性變低,結果,於該區域中容易曲折,而可提昇服貼性。 再者,於以頂層片材側之吸收體之面為基準時,交叉區域之凹陷之深度既可以與薄化部之凹部之深度一致之方式(即,沿格子出現均一之深度之槽)形成,亦可以不一致之方式(例如以變淺之方式)形成。 首先,於以下說明將本發明應用於拋棄式展開型尿布(以下,「展開型尿布」,或於本實施形態中亦簡稱為「尿布」)之一實施形態。 <構成> 於圖30表示本發明之一實施形態之尿布之一例之外觀中自正面側觀察之立體圖。本實施形態之尿布5010係展開型尿布,且具有:前身片區域5010F、後身片區域5010R、及連接該等前身片區域5010F及後身片區域5010R之***區域5010C。又,形成有於穿著時以前身片區域5010F與後身片區域5010R包圍穿著者之腰之部分之腰圍開口部5010W。同樣,形成有以前身片區域5010F及後身片區域5010R之下端部與***區域5010C包圍穿著者之兩腿之大腿肚部分之左右一對腿圍開口部5010L。 於穿著時前身片區域5010F位於穿著者之腹側,後身片區域5010R位於穿著者之背側。並且,於穿著時***區域5010C覆蓋穿著者之***,而成為穿著者之腿分別通過左右一對腿圍開口部5010L之樣式。因此,腿圍開口部5010L位於穿著者之兩腿之自根部至大腿肚附近之任意位置。 假想線P係於尿布中央部自腹側朝向背側通過***部分延伸者。具體而言,假想線P係例如:若以展開型尿布之腰側定義為上、***側定義為下,則沿尿布之表面且沿上下方向延伸,並且經由***部分,於背側亦沿上下方向延伸者。 於位於展開型尿布5010之外側之覆蓋片5011之後身片區域5010R之左右兩端緣部,接著有於穿著時重疊於前身片區域5010F之左右兩端緣部而連接該等,而可形成腿圍開口部5010L之左右一對黏扣帶5010A。該黏扣帶5010A係相對於接著於前身片區域10F之覆蓋片5011上之前貼片片材5010B可反覆剝離地接著。 圖31係圖30所示之展開型尿布10之模式性分解立體圖,圖32係自頂層片材14側觀察本發明之一實施形態之伸展狀態之尿布5010之模式性俯視圖。對於圖31之吸收體5013及圖32之展開型尿布5010,為了便於說明而分別表示局部破斷之狀態。 如圖31所示,本實施形態之展開型尿布5010具有積層構造,該積層構造係自外側依序重疊為了獲得良好之手感而以較薄之不織布形成之覆蓋片5011、具有不透液性之底層片材(背面片材)5012、細長之吸收體5013、具有透液性之頂層片材(正面片材)5014、及以撥水性之片材構件構成之一對立體皺褶(側部片材)5015而成。 於覆蓋片5011之***區域5010C之左右兩側,分別形成有成為腿圍開口部5010L之一對缺口部5011N。於覆蓋片5011與一對立體皺褶5015之間,將用於形成腿圍皺褶之一對橡膠線5016分別以伸展狀態接著。 底層片材5012係接合於覆蓋片5011,且吸收體5013係配置於該底層片材5012與頂層片材5014之間,隔著該吸收體5013將頂層片材5014接合於底層片材5012。又,於底層片材5012之中對應於後身片區域5010R之上端部之區域,接合有沿底層片材5012之寬度方向延伸、且用於對穿著者賦予於腰圍適度之穿著感之彈性片材5010D。 位於頂層片材5014之下之本實施形態之吸收體5013係藉由薄紙或不織布等被覆構件(包芯材)5018包覆主要包含紙漿與SAP之吸收性本體5017之墊狀者。於本實施形態中,吸收體本體5017雖為包含SAP者,但本發明中亦可為不包含SAP者。藉由利用被覆構件5018包覆吸收性本體5017而形成之接縫係例如如圖31所示,以於吸收體5013之上表面且沿長度方向延伸之方式形成。本實施形態之吸收體5013係以遍及前身片、***、後身片之方式,呈細長之形狀。此處,若將自前身片部分向後身片部分設為前後(上下)方向,並將與其正交之方向設為左右方向,則本實施形態之吸收體5013為前後(上下)左右之長度不同之矩形者(於圖31及圖32中,前後(上下)之長度長於左右之長度)。再者,本實施形態之吸收體5013之形狀並不限於此,包含例如前後(上下)左右之長度為同等程度之大致正方形者、前後(上下)端之角切成圓形者、於前後(上下)延伸之橢圓形者、圓形者等各種形狀。又,於吸收體5013之***部分,亦可以與一對腿圍開口部5010L對應之方式,形成呈圓弧狀之一對缺口部。於本實施形態中,如圖32所示,於吸收體5013之表面,連續地形成複數個凹部5020並排列成斜向格子狀。藉由連續地形成凹部5020,空氣能夠通過腹側或背側,從而可確保透氣性。又,於本實施形態中,於吸收體5013,於複數個凹部5020交叉之區域中,以該區域之底層片材5012側***之方式設置***部(參照下述之圖33之符號5021)。該等凹部5020及***部係例如藉由利用旋轉之2個輥夾持壓縮吸收體5013而分別形成(參照下述之圖37)。 一對立體皺褶5015係沿吸收體5013之長度方向設置且沿吸收體5013之長度方向延伸之兩側緣部之中,一側緣部呈大致直線形狀,於另一側緣部,於***附近形成有缺口部5015N。一對立體皺褶5015之內側部分相對於頂層片材5014成為非接合狀態,且立體皺褶5015於其大致直線形狀之側緣部包含自由端。於立體皺褶5015之自由端,如圖32所示,沿吸收體5013之長度方向以伸展狀態配置有作用拉伸力之彈性構件即橡膠線5019。一對立體皺褶5015藉由該橡膠線5019而可於穿著狀態下沿吸收體5013之兩側緣部立起。 <凹部及***部> 圖33係對圖32之XXXIII-XXXIII方向剖面予以表示之模式圖。該XXXIII-XXXIII方向之剖面指示線於圖32中係以通過複數個凹部5020交叉之區域之中央部之方式劃出。亦即,圖33所示之2個凹部5020係指複數個凹部5020交叉之區域者。圖34係對圖32中之XXXIV-XXXIV方向剖面予以表示之模式圖。該XXXIV-XXXIV方向之剖面指示線於圖32中係以通過自複數個凹部5020交叉之區域偏離之位置之方式劃出。亦即,圖34所示之4個凹部5020係指複數個凹部5020不交叉之區域者。圖35係對圖32中之XXXV-XXXV方向剖面予以表示之模式圖。又,圖36係本實施形態之自頂層片材5014側觀察吸收體5013之模式性俯視圖。圖36所示之實線表示凹部5020,複數個點狀之影線區域表示***部5021。圖36所示之虛線係以包含複數個***部5021之方式於吸收體5013之長度方向劃出者,且係對應於在下述之圖37所說明之「第2輥5040之凹陷部5041」者。 如圖33所示,於相當於複數個凹部5020交叉之區域之下方之位置、且吸收體5013之底層片材5012側,分別形成有***部5021。亦即,***部5021於複數個凹部5020交叉之區域中,形成於對應於該區域之吸收體5013之底層片材5012側。於本實施形態中,***部5021係以對應於第1凹部5020a與第2凹部5020b交叉之區域的吸收體5013之底層片材5012側較對應於該交叉區域以外之第1凹部5020a或第2凹部5020b的吸收體5013之底層片材5012側更***之方式形成。此處,對應於該交叉區域以外之第1凹部5020a或第2凹部5020b的吸收體5013之底層片材5012側如圖34所示係對應於複數個凹部5020不交叉之區域的吸收體5013之底層片材5012側。可看到圖33所示之凹部5020下方之吸收體5013之底層片材5012側之表面比圖34所示之凹部5020下方之吸收體5013之底層片材5012側之表面更***。 因藉由於複數個凹部5020交叉之區域形成該***部5021,而於吸收體5013之該部分中壓縮之程度較小,故紙漿或SAP之結合變弱,結果,吸收體5013於複數個凹部5020交叉之區域容易彎曲,而可提昇尿布10之服貼感。 於本實施形態中,***部5021之***雖如圖33所示般以向展開型尿布5010之外側突出之方式形成,但本發明中,並不限於此。若***部5021以相對於與上述交叉之區域以外之凹部5020之底部對應之表面***之方式形成,則***部5021亦可不以向尿布5010之外側突出之方式形成。其可例舉例如對應於複數個凹部5020不交叉之區域之吸收體5013之背面片材5012側之表面相對於尿布5010向內側凹陷之情形。 又,於本實施形態中,***部5021至少形成於複數個凹部5020交叉之區域。於本發明中,亦可於對應於交叉之區域以外之第1凹部5020a或第2凹部5020b的吸收體5013之背面片材5012側形成***部5021。藉由該構成,吸收體5013中交叉之區域以外之凹部5020之底部變柔軟,故可進一步使服貼感提昇。 對應於凹部5020之底部之吸收體5013中包含被覆構件5018之最薄部分之厚度為0.1 mm~1.0 mm對有效地發揮本發明之效果而言較佳。又,吸收體5013中對應於形成有***部5021之凹部5020之區域之厚度較佳為較上述最薄部分之厚度厚0.1 mm~1.0 mm,且厚0.2 mm~0.4 mm對有效地發揮本發明之效果而言更佳。該情形時,混合SAP與紙漿而成之吸收性本體(吸收墊)5017之基重之範圍為170 g/m2 ~600 g/m2 較合適,且為240 g/m2 ~530 g/m2 更合適(紙漿之基重之範圍為80 g/m2 ~300 g/m2 較合適,且為160 g/m2 ~240 g/m2 更合適)。 轉移至圖36,於吸收體5013之頂層片材5014側,如圖36所示,形成有沿第1方向延伸之第1凹部5020a、與相對於第1凹部5020a以交叉狀態沿與第1方向不同之第2方向延伸之第2凹部5020b。且,第1凹部5020a及第2凹部5020b係以相互平行排列之複數個薄化部分別構成。又,***部5021係如圖36所示般,於對應於第1凹部5020a與第2凹部5020b交叉之區域的吸收體5013之底層片材5012側,以相對於對應於第1凹部5020a或第2凹部5020b之底部之表面更***之方式形成。 於本實施形態中,凹部5020係形成為沿吸收體5013之長度方向(圖36中之上下方向)之帶狀,而非形成至吸收體13之寬度方向(圖36中之左右方向)之端部。將吸收體13之形成有凹部5020之區域設為凹部形成區域N1,且將吸收體5013之未形成凹部5020之寬度方向兩端部之區域設為凹部非形成區域N2。於本實施形態中,具備凹部非形成區域N2,但本發明不限於該形態,當然亦可將凹部5020設置至吸收體5013之端部。因此,本發明亦可為不設置凹部非形成區域N2之構成。又,本發明係容許凹部5020未形成至吸收體5013之長度方向(圖36中之上下方向)之端部之態樣、或形成至該端部之態樣者。於形成至該端部之情形時,可提昇透氣性及防悶。 本實施形態中,凹部5020係由吸收體5013之寬度方向上之向一側(圖36中,朝向右側)傾斜延伸之第1凹部5020a、與向另一側(圖36中,朝向左側)延伸之第2凹部5020b構成。假想線P之於吸收體5013上之位置成為自前身片部分上端朝向後身片部分下端延伸者。具體而言,如圖36所示,於吸收體5013為細長形狀之情形時,為沿長度方向延伸者。凹部5020相對於該假想線P傾斜而延伸。即,相對於以假想線P為軸沿側邊之方向、例如長度方向,第1凹部5020a向一側以角度α傾斜,第2凹部5020b向另一側以角度β傾斜。角度α與角度β既可相同,亦可不同。又,於圖36中,複數個第1凹部5020a分別以相同角度傾斜,並以固定間隔配置。即,將各第1凹部5020a平行且以固定間隔配置,但本發明並不限於此,亦包含凹部5020之間隔並不固定者、或各凹部5020之傾斜角度不同者。關於第2凹部5020b亦相同。 又,於本實施形態中,***部5021係如圖36所示般,至少具有一對平行之輪廓,且複數個***部5021係沿斜向格子整齊排列,相互平行地形成。進而,藉由***部5021具有平行之輪廓,可使吸收體5013容易於該輪廓部分曲折。因此,藉由決定***部5021之輪廓形狀,可任意地設定吸收體5013之曲折部分。 根據本實施形態之尿布5010之構成,於複數個凹部交叉之區域中使柔軟性提昇,而容易將吸收體5013於複數個凹部曲折,故可提昇尿布5010之服貼性。 圖37係用以說明本發明之一實施形態之以2個輥夾持壓縮吸收體5013之情況之圖,圖38A及圖38B係以凸部5031與凹陷部5041夾持壓縮吸收體時之剖視圖,圖38A係MD方向(行進方向)上者,圖38B係CD方向(寬度方向)上者。圖38A及圖38B之剖面係以通過複數個凹部5020交叉之區域之中央部之方式切斷者。亦即,圖38A及圖38B所示之凹部5020分別表示複數個凹部5020交叉之區域。 製造本實施形態之尿布5010之製造裝置5100構成為具備第1輥(第1旋轉構件)5030、及與第1輥5030一併旋轉之第2輥(第2旋轉構件)5040。第1輥5030具有形成有凸部5031之外周面部,且抵接於吸收體5013之頂層片材5014側之面。第2輥5040具有形成有凹陷部5041之外周面部,且抵接於吸收體5013之底層片材5012側之面。亦即,吸收體5013係藉由第1輥5030與第2輥5040一併旋轉、且被夾在該等輥間而形成壓紋圖案。 凸部5031包含:第1凸部5031a,其係以形成第1凹部5020a之方式構成,且沿對應於第1方向(圖36所示之第1凹部5020a之形成方向)之第3方向延伸;及第2凸部5031b,其係以形成第2凹部5020b之方式構成,且以相對於第1凸部5031a交叉之狀態,沿對應於與第3方向不同之第2方向(圖36所示之第2凹部5020b之形成方向)之第4方向延伸。 凹陷部5041配置於第2輥5040之中、對應於第1凸部5031a與第2凸部5031b交叉之區域之位置。於本實施形態中,凹陷部5041係以相互平行地排列之複數個凹陷形成。因此,因凹陷部5041為簡單之構造,故可容易地形成於第2輥5040。 對有效地發揮本發明之效果而言,第1輥5030之凸部5031與第2輥5040之凹陷部5041之關係中,第1輥5030之徑向上之凸部5031之高度(厚度)較佳為2 mm~20 mm,且更佳為5 mm~10 mm。又,第2輥5040之徑向上之凹陷部5041之深度較佳為0.05 mm~5 mm,更佳為0.1 mm~0.5 mm。 本實施形態之尿布5010係例如藉由以下之製造方法或用以實施該方法之製造裝置製造。 首先,利用被覆構件5018包覆由紙漿與SAP構成之吸收性本體5017,產生連續之墊狀之吸收體5013。 然後,如圖37所示,一面第1輥5030向B方向旋轉且第2輥5040向C方向旋轉,一面夾持自MD方向之上游於A方向流動來之連續之吸收體5013,而對連續之吸收體5013實施壓紋加工。藉由該壓紋加工,於連續之吸收體5013形成凹部5020及***部5021。具體而言,藉由第1輥5030,以形成第1凹部5020a與第2凹部5020b之方式,壓縮連續之吸收體5013之頂層片材5014側,與此同時,藉由第2輥5040,以於對應於第1凹部5020a與第2凹部5020b交叉之區域的吸收體5013之底層片材5012側形成***部5021之方式,使連續之吸收體5013之底層片材5012側變形。亦即,格子線即凹部5020之交叉區域容許吸收體5013向第2輥5040之凹陷部5041內之變形,而成為即便自第1輥5030按壓亦不產生壓縮(即不成為高密度)、或實質上不產生壓縮之部位。 其次,將壓紋加工後之連續之吸收體5013流向MD方向之下游,並藉由切斷裝置按每1片尿布份量所需之長度切斷,於將頂層片材5014、底層片材5012、覆蓋片5011等接合之後,製造尿布10。 於本實施形態中,藉由壓縮吸收性本體5017與被覆構件5018,形成凹部5020及***部5021,但本發明並不限於此。例如,亦可藉由對將吸收性本體5017、被覆構件5018(即吸收體5013)及頂層片材5014積層而成者進行壓縮(參照下述之圖39)、或僅壓縮吸收性本體5017,而形成凹部5020及***部5021。僅壓縮吸收性本體5017之情形時,亦可對該吸收性本體5017使用不包含SAP者。 於對將吸收體5013與頂層片材5014積層而成者進行壓縮之情形時,亦可對將預先分開(例如切斷)之吸收體5013與頂層片材5014接合而成者實施壓縮。圖39係用以對本發明之其他實施形態之以2個輥夾持壓縮吸收體5013及頂層片材5014之情況予以說明之MD方向上之模式性剖視圖。頂層片材5014係如圖39所示般連續。複數個吸收體5013係分別預先被積層而成為墊狀,且分成1片尿布10之份量。複數個吸收體5013係如圖39所示般,分別空出固定間隔,接合(例如接著)於連續之頂層片材5014。 將複數個吸收體5013與頂層片材5014積層而成者係如圖39所示般,向A方向行進,與上述實施形態同樣地,由製造裝置5100之第1輥5030與第2輥5040夾持壓縮。藉此,將吸收體5013與頂層片材5014一併夾持壓縮,而於將吸收體13與頂層片材5014積層而成者,形成凹部5020及***部5021。於壓縮後之吸收體5013及頂層片材5014,接合底層片材5012、覆蓋片5011等,並切斷為所需之長度,而製造1片尿布10。 又,於本實施形態中,雖藉由以第1輥5030及第2輥5040夾持壓縮,而於吸收體5013之底層片材5012側設置***部5021,但並不限於此,於本發明中,例如亦可藉由吸引吸收體5013之底層片材5012側而設置***部5021。 可對上述之第5實施形態,進行適當之變更或變化。 例如,本發明之尿布之構造並非限定於如上述般之展開型,只要為包含申請專利範圍所規定之吸收性物品之構成之尿布,則可為任意之構成。例如,即便為如圖1所示般之尿褲型尿布、或其他尿墊等亦可應用本發明。 此外,於上述實施形態中,雖藉由於吸收體5013之表面連續形成複數個凹部5020,而製成斜向格子狀之排列圖案,但並不限於此。於本發明中,只要存在複數個凹部5020交叉之區域,則例如亦可於吸收體5013之表面間斷地形成複數個凹部5020,且凹部5020之排列圖案亦可為例如三角形、六邊形等多邊形之排列圖案、將直線狀、曲線狀、或波狀者並列之圖案等各種排列圖案。 上述實施形態中,於凹部5020及***部5021中,頂層片材5014、吸收體5013、底層片材5012、及覆蓋片5011整面接合,但於本發明中,亦可局部地接合。 於上述實施形態中,第1凸部5031a與第2凸部5031b之山之高度相等,亦即,第1凹部5020a與第2凹部5020b之底部之深度相等,但本發明係即便不相等亦可發揮複數個凹部交叉之區域變柔軟之效果者。關於複數個凹陷部5041之深度或複數個***部5021之***部分之高度亦同樣,可各不相等。 進而,於上述實施形態中,並不限於圖33至圖39所示之***部5021、凸部5031、凹陷部5041之各形狀或各圖案,本發明中,亦可包含如以下之變化例。 圖40A及圖40B係表示第1輥5030之表面之凸部圖案之2例之俯視圖,圖40A表示斜向格子狀之圖案,圖40B表示縱橫格子狀之圖案。圖41A~圖41D係表示第2輥5040之表面之凹陷部圖案之例之俯視圖,圖41A表示縱(第2輥5040之周向)條紋狀之圖案,圖41B表示棋盤格花紋之圖案,圖41C表示將菱形整齊地排列成斜向格子狀之圖案,圖41D表示將正方向整齊地排列為縱橫格子狀之圖案。圖42A~圖42F係表示形成於吸收體5013之***部圖案之例之圖,圖42A表示將蝶形整齊排列為斜向格子狀之圖案,圖42B表示大致斜向十字連續之圖案,圖42C表示將菱形整齊地排列成斜向格子狀之圖案,圖42D表示縱條紋狀之圖案,圖42E表示將正方向整齊地排列為縱橫格子狀之圖案,圖42F表示將X形整齊排列成斜向格子狀之圖案。於圖40A及圖40B中以點狀之影線表示凸部5031,於圖41A至圖41D中以網眼狀之影線表示凹陷部5041,於圖42A至圖42F中以複數條斜線之影線表示***部5021。圖40A、圖41A及圖42A為與上述實施形態相同之圖案。再者,第1凸部5031a與第2凸部5031b交叉之區域、與凹陷部5041係以分別對應之方式配置,且以於第1輥5030及第2輥5040旋轉時相互重疊之方式,與該等2個輥之旋轉取得同步者。 形成於第1輥5030之表面之凸部圖案、形成於第2輥5040之表面之凹陷部圖案、及形成於吸收體13之***部圖案可設為各種形狀,且可進行各種組合。例如,若以具有圖40A所示之凸部圖案之第1輥5030、與具有圖41B所示之凹陷部圖案之第2輥5040夾持吸收體5013,則於吸收體5013形成如圖42B所示之大致斜向十字連續之圖案之***部5021。藉由***部5021成為該形狀,吸收體5013之中,除形成於複數個凹部5020交叉之區域之***部5021以外,於複數個凹部5020不交叉之區域亦形成***部5021,而對於複數個凹部5020不交叉之區域亦增加柔軟性,因此,可進一步提昇服貼性。 又,若以具有圖40A所示之凸部圖案之第1輥5030、與具有圖41C所示之凹陷部圖案之第2輥5040夾持吸收體5013,則於吸收體5013形成如圖42C所示之菱形之圖案之***部5021。 進而,若以具有圖40B所示之凸部圖案之第1輥5030、與具有圖41A所示之凹陷部圖案之第2輥5040夾持吸收體5013,則於吸收體5013形成如圖42D所示之縱條紋狀之圖案之***部5021。藉由***部5021成為該形狀,吸收體5013之中,除形成於複數個凹部5020交叉之區域之***部5021以外,於複數個凹部5020不交叉之區域亦形成***部5021,從而具有如於圖42B所說明之效果。 且,若以具有圖40B所示之凸部圖案之第1輥5030、與具有圖41D所示之凹陷部圖案之第2輥5040夾持吸收體5013,則於吸收體5013形成如圖42E所示之正方形之圖案之***部5021。 此外,於使用具有圖40A所示之凸部圖案之第1輥5030夾持吸收體5013之情形時,若使用將圖41A之複數個凹陷部5041之寬度分別擴寬者,則於吸收體5013形成如圖42F所示之X形之圖案之***部5021。於本發明中,當然並非限於上述之圖案或組合。此外,作為第1輥5030之表面之凸部圖案之例,列舉橫(CD方向)或傾斜方向之條紋狀之圖案、採用曲線之圖案等。此點關於凹陷部圖案亦相同。又,於圖42A至圖42F中,***部5021以直線構成,但於可獲得本發明之效果之範圍內亦可為曲線。 又,上述之複數個***部5021各者形狀或大小(面積)相同,但於本發明中,亦可不同。例如,亦可於欲使吸收體5013大幅度彎曲之部位設置較大之***部5021。所謂欲大幅度彎曲之部位係例如於***區域5010C之兩旁側(腿側)欲將吸收體5013設為袋狀之處所、***區域5010C與後身片區域5010R(背側)之邊界線部分、***區域5010C與前身片區域5010F(腹側)之邊界線部分、欲使其沿穿著者之身體之曲線變形之腰圍等。 又,於上述實施形態中,並不限於圖38A及圖38B所示之凹陷部5041之剖面形狀,於本發明中,亦可如以下般變化。 圖43A及圖43B係表示凹陷部5041之剖面形狀之2例之圖,圖43A表示梯形形狀,圖43B表示側壁成為2段之凹陷。圖43A係與上述實施形態同樣之凹陷部5041之剖面形狀。即便藉由利用具有側壁成為2段之凹陷之凹陷部5041與凸部5031夾持壓縮吸收體5013,亦可與上述實施形態同樣地形成凹陷部5041,故可於凹部交叉之區域獲得柔軟性。1. In the description of the specification and the patent application, "lattice" means a group of first straight lines extending in parallel with the first direction and a second straight line extending in parallel with the second direction intersecting the first direction. The group is defined, but the first and second directions may not be orthogonal. The "intersection point" refers to a portion which is a lattice line of the first straight line and intersects the lattice line which is the second straight line, but may be referred to as a "lattice point" in the following description. "Compression" means reducing the thickness of the absorber by the action of force to increase the density. On the other hand, "pressing" does not mean that the thickness of the absorber is necessarily reduced by the action of the force, and the density is increased. That is, for example, the case where the force is applied to the intersecting region causes a bulge due to the surface on the opposite side of the absorbent body, and substantially the thickness of the absorbent body is not reduced, and the density is not increased. Moreover, "compression" or "pressing" is not only directly generated by the action of force, but also includes an indirect connection caused by the sinking of the action part following the direct force. Further, in the description of the present specification and the patent application, the "thinned portion" refers to a linear region which is formed along a lattice line of a lattice and has a portion which is more concave than a surface on the front sheet side of the absorbent body. The "thinning portion" is defined as a boundary between the intersection portion including the intersection of the lattice lines and the periphery thereof, that is, extending between the intersection region and the intersection region so as not to exceed the intersection region. Further, the "thinned portion" may be a shape of a long groove which is a continuous concave portion in the extending range (which is mainly exemplified in the second to fifth embodiments), or may have a plurality of concave portions which are discontinuous. Shape (in the first embodiment, the shape is mainly exemplified). 2. First Embodiment of the absorbent article Hereinafter, a first embodiment of the absorbent article of the present invention will be described in detail with reference to the drawings. In addition, this embodiment is described as being applied to a disposable diaper type diaper (hereinafter also referred to as "diaper type diaper" or "diaper only"). The diaper type diaper can be applied to adults and children. Further, in the present embodiment, the diaper diaper is described as an example, but it is of course also applicable to the unfolded diaper (so-called diaper) described in the fifth embodiment. Further, the absorbent article of the present invention is not limited to only a diaper, but is applied to an absorbent pad or the like and other general absorbent articles as a whole. For example, as shown in Fig. 5, the present invention can also be applied to an absorbent pad or the like in terms of the structure of the absorbent body 13 and the portion of the top sheet 14, and has the same effects as those of the diaper. That is, the present invention is not limited to the embodiments and the other embodiments described below, and includes other absorbent articles that are subject to the concept of the present invention. First, the overall shape of the diaper-type diaper to which the absorbent article according to the first embodiment of the present invention is applied will be described with reference to Figs. 1 to 4 . Fig. 1 is a perspective view showing the appearance of the diaper-type diaper to which the absorbent article of the present embodiment is applied, viewed from the front side. Fig. 2 is a developed view of the diaper-type diaper of the embodiment. The diaper cloth 10 of the present embodiment has a front body region 10F, a back body region 10R, and a crotch region 10C connecting the front body region 10F and the back body region 10R. Further, a waist opening portion 10W that surrounds the waist of the wearer in the front body region 10F and the back body region 10R at the time of wearing is formed. Similarly, a pair of left and right leg openings are formed in any region of the region from the thigh root to the vicinity of the thigh, which is formed by the lower body portion 10F and the lower body region 10R and the underarm region 10C surrounding the wearer's legs. Department 10L. When the diaper-type diaper 10 is worn, the front body panel region 10F is located on the ventral side of the wearer, and the back body panel region 10R is located on the back side of the wearer. Further, the crotch region 10C covers the underarm of the wearer, and the leg of the wearer passes through the left and right pair of leg-opening portions 10L. Therefore, the leg-opening portion 10L is located at any position from the root portion to the vicinity of the calf in the legs of the wearer. The diaper-type diaper 10 is provided with a cover sheet 11 so as to cover the front body piece region 10F and the back body piece region 10R together with the crotch region 10C, and the left and right side edges of the cover sheet 11 are joined to each other to form a closed portion. 10J. Thereby, the waist opening portion 10W and the pair of left and right leg circumference opening portions 10L are divided. In the diaper-type diaper 10 of the present embodiment, an imaginary line P extending through the crotch region 10C from the ventral side toward the back side in the center of the diaper-type diaper 10 in the width direction or in the vicinity thereof is assumed. Specifically, the imaginary line P is extended along the ventral surface of the diaper 10 and in the up-and-down direction, for example, when the diaper-type diaper 10 is worn with the waist side as the upper side and the lower squat side as the lower side, and is passed through the underarm area. 10C, and the back side also extends along the surface of the diaper-type diaper 10 in the up and down direction. In the diaper-type diaper 10 of the present embodiment, the absorbent body 13 is elongated along the imaginary line P, and its longitudinal direction is parallel to the imaginary line P. Further, the direction orthogonal to the imaginary line P is defined as the width direction. Further, the ratio of the longitudinal direction to the width direction of the diaper-type diaper can be appropriately changed depending on the body type of the wearer. As shown in FIG. 2, in the center of the left and right side edge portions in the longitudinal direction of the cover sheet 11, one of the semi-arc-shaped notch portions 11A which is the leg-surrounding opening portion 10L of Fig. 1 is formed. The absorber 13 having an elongated rectangular shape is disposed on the surface of the cover sheet 11 that is in contact with the wearer's skin so as to extend over the front body region 10F, the crotch region 10C, and the back body region 10R. The absorbent body 13 is joined to the back sheet 12. The back sheet 12 joined to the absorber 13 is joined to the cover sheet 11 such that the longitudinal direction thereof is substantially parallel to the imaginary line P and the imaginary line P passes through the center of the width direction or a position in the vicinity thereof. On the surface of the absorbent body 13, a liquid permeable top sheet 14 that is in contact with the wearer's skin is joined. The cover sheet 11 is joined with a rubber thread 15 for forming a leg gather wrinkle and a rubber thread 17 for forming a waist gather, respectively, in an extended state. Further, the left and right side edges of the top sheet 14 are provided with a side sheet 18 which forms one of the three-dimensional gathers. The pair of side sheets 18 are members for liquid impervious to stand on both side edges of the absorbent body 13 at the time of wearing to prevent side leakage of urine excreted by the wearer. Each of the side sheets 18 is provided with a rubber thread 19 as a three-dimensional gather stretch material in a shape in which the inner end edge portion thereof is folded back and held toward the absorber 13 side, and is worn toward the wear when the rubber thread 19 is contracted. The skin of the person stands up in the direction of contact. The three-dimensional wrinkles can be used in the well-known construction of previous diapers. For example, it can be formed by sandwiching and fixing the three-dimensional pleated stretch material in an extended state between the layers of the water-repellent sheet. Fig. 3 is a perspective view showing an exploded state in which the diaper diaper 10 of the present embodiment is broken and unfolded. The laminated structure of the diaper diaper 10 will be described with reference to Fig. 3 . As shown in FIG. 3, the diaper-type diaper 10 sequentially overlaps and joins the cover sheet 11, the liquid-impermeable back sheet 12, the absorbent body 13, and the top sheet 14 from the outside. The cover sheet 11 on which the pair of notch portions 11A are formed is formed by the inner cover sheet 11B on the skin side of the wearer and the outer cover sheet 11C joined to the outer side of the inner cover sheet 11B. The inner cover sheet 11B is joined to the back sheet 12. The absorbent body 13 is disposed between the back sheet 12 and the top sheet 14, and joins the top sheet 14 to the back sheet 12 via the absorbent body 13. The outer cover sheet 11C is formed of a thin non-woven fabric in order to obtain a good hand feeling, and rubber lines 15 and 17 are respectively joined between the inner cover sheet 11B and the outer cover sheet 11C in an extended state. Further, the left and right side edges of the top sheet 14 are provided with a side sheet 18 which forms one of the three-dimensional gathers. The pair of side sheets 18 are members for erecting along the both side edges of the absorbent body 13 at the time of wearing to prevent side leakage of urine excreted by the wearer. Each of the side sheets 18 has a rubber thread 19 as a three-dimensional gather stretch material in a shape in which the inner end edge portion is folded back and held toward the absorber 13 side. Further, the base sheet 12, the absorbent body 13, and the top sheet 14 may be used to form an absorbent article which is joined to a pair of pants or the like to absorb liquid. Fig. 4 is a cross-sectional view showing the diaper diaper 10 of the present embodiment taken along line IV-IV of Fig. 2 . The cross-sectional shape of the absorber 13 of the diaper diaper 10 will be described with reference to Fig. 4 . On the surface of the top sheet 14, the absorbent body 13 and the top sheet 14 are compressed by intermittent embossing to integrally form a plurality of concave portions of a quadrangular shape. The thin portions 401 which function as a groove for allowing a liquid such as urine to pass through are formed by arranging a plurality of concave portions at intervals. The thinned portion 401 has a depth from the side of the top sheet 14 side of the absorber 13 toward the side of the back sheet 12 . A portion surrounded by the thinned portion 401 formed on the surface of the absorber 13 is referred to as a deformation suppressing portion 402. Details of the deformation suppressing portion 402 will be described later. Further, the ridge line at the upper portion of the thinned portion 401 indicates the outline 403 of the portion of the non-thinned portion 401 which is seen when cut in the cross section. Next, the absorbent body 13 of the diaper diaper 10 of the present embodiment will be described with reference to Figs. 5 and 6 . Fig. 5 is a plan view showing the upper surface of the absorbent body 13 of the diaper diaper 10 of the present embodiment on the side of the top sheet 14. The surface shape of the absorber 13 will be described with reference to Fig. 5 . The absorbent body 13 is mainly composed of pulp and SAP. The absorber 13 has an elongated rectangular shape so as to extend over the front body region 10F, the crotch region 10C, and the back body region 10R. The absorber 13 is divided into three parts of the front body piece portion M1, the crotch portion M2, and the back body piece portion M3 in the longitudinal direction. Further, in the crotch portion M2, a pair of left and right leg-opening portions 10L surrounding the thigh portions of the wearer's legs may be formed to form one of the arc-shaped notch portions. The absorber 13 is in the front (upper) direction from the lower body portion M2 to the front body portion M1, and is in the rear (lower) direction from the lower jaw portion M2 toward the rear body portion M3, and in the front-rear direction (length) Direction) The direction orthogonal to the left and right direction (width direction). Further, the absorber 13 is rectangular, but the shape of the absorber of the present invention is not limited thereto. For example, the shape of the absorber includes a shape in which the angles of the front and rear (upper and lower) ends are cut into a circle, an ellipse extending in the front and rear (up and down), a circle, and a length of the front and rear (up and down) are equal to each other. Various shapes. Further, in the absorber 13, a thinned portion 501 extending in a diagonal lattice shape is formed. In the present embodiment, the thinned portion 501 extends from one end of the thinned portion forming region N1 toward the other end in a staggered lattice shape. Further, the thinned portion 501 formed as a result of being compressed around the concave portion 502 of the absorbent body 13 may be intermittent or intermittent depending on the interval and depth of the concave portion 502, and may be continuous or both. Mix of. Moreover, the absorber 13 is covered with a core material (thin paper) not shown. The core material is a relatively thin sheet of hydrophilicity. Further, in the present embodiment, the absorber 13 coated with the core material is used, but the absorber of the present invention may not be coated with the core material. This point is also the same in the other embodiments described below. As shown in FIG. 5, in the present embodiment, the thinned portion 501 is formed in the thinned portion forming region N1 by patterning a plurality of concave portions 502 at a predetermined interval. The thinned portion 501 is formed from one side in the width direction (left-right direction) of the absorber 13 orthogonal to the direction (longitudinal direction) indicated by the imaginary line P in the longitudinal direction of the absorber 13 to the other lower side ( a plurality of first thinned portions (first patterns) 501a in the first direction obliquely extending toward the paper surface in FIG. 5 from the upper right side to the lower left side, and the lower side from the other upper side (the paper surface in FIG. 5) The upper left side to the lower right side is configured by a plurality of second thinned portions (second patterns) 501b that are obliquely extended in the second direction. Each of the first thinned portions 501a is arranged parallel to each other and at a predetermined interval. Similarly, each of the second thinned portions 501b is arranged parallel to each other and at a predetermined interval. However, the plurality of thinned portions 501 may not be completely parallel to each other, and may not be fixed to each other. In FIG. 5, the plurality of first thinned portions 501a are inclined at the same angle with respect to the imaginary line P, and are arranged at a specific interval. In other words, each of the first thinned portions 501a is arranged in parallel and at a predetermined interval. However, the present invention is not limited thereto, and includes a case where the interval between the thinned portions is not fixed or the inclined portions of the thinned portions are different. The same applies to the second thinned portion 501b. Further, in the absorber 13, the first thinned portion 501a and the second thinned portion 501b are each formed in a plurality of strips. However, if the first thinned portion and the second thinned portion are formed in the oblique direction, the first thinned portion and the second thinned portion are formed. The number of thinning portions is not limited. Although it is preferable to cross the two, the present invention is not limited thereto, and includes a case where the two do not intersect. Details regarding the role of the thinning portion are described below. Further, the absorber 13 has a thinned portion forming region N1 in the central portion in the width direction, and has a thinned portion non-formed region N2 on both sides thereof. Both side edges in the width direction of the absorber 13 are thinned portion non-formation regions N2, and in the central region, the thinned portion forming region N1 extends in a strip shape from one end in the direction indicated by the imaginary line P toward the other end. Fig. 6 is a partial cross-sectional view showing the diaper diaper 10 of the present embodiment based on a line VI-VI of Fig. 5. In the thinned portion 501, the member 13 having the specific thinned portion pattern is formed on the surface of the top sheet 14 of the self-absorbent body 13, and the absorbent body 13 is compressed while being heated to form the concave portion 502. Further, the width and depth of each thinned portion 501 may be uniform, or may vary depending on the interval from the adjacent thinned portion, the position of the thinned portion, and the like. Further, the side wall portion of the concave portion 502 provided in the thinned portion 501 may be a V-shaped obliquely inclined from the surface of the absorber as shown in FIG. 6, or may be a substantially vertical extension. Further, the ridge line at the upper portion of the concave portion 502 indicates the outline 601 of the portion of the non-recessed portion 502 which is seen when cut in the cross section. By the above-described compression for forming the thinned portion 501 having the concave portion 502, the thinned portion concave portion 502 and the vicinity thereof (including the gap portion between the concave portions) are more compressed than the other portions, thereby enhancing the absorbent body 13 The density. The compression ratio of the thinned portion concave portion 502 having the largest degree of compression is preferably about 4 times to 7 times, and the range of other compression ratios is also included depending on the material of the absorbent body 13 or the liquid to be absorbed. Further, the density of the absorber in the compressed portion is twice or more as compared with the uncompressed portion. The density of the absorbent body is mainly the density of the pulp. As described above, the concave portion 502 of the thinned portion 501 in the absorbent body 13 is formed by compressing the absorbent body 13. Therefore, the concave portion 502 of the thinned portion 501 and, as the case may be, the absorbent body 13 is compressed to a greater extent and harder than the other portions of the absorbent body 13. Further, since the deformation suppressing portion 402 presses the outer peripheral portion of the absorption in the deformation suppressing portion 402 by the concave portion 502, it is less likely to be deformed. Therefore, even if the tensile force is generated in the oblique direction with respect to the longitudinal direction, the absorbent body 13 is less likely to be twisted and twisted due to the rigidity of the concave portion 502, and the deformation suppressing portion 402 is not easily deformed, and as a result, the tilting direction is suppressed. The deformation. Therefore, even after the front and rear movement of the leg, the absorbent body 13 is not deformed and deformed. Since the absorbent body 13 is not twisted, the conformity to the sputum can be maintained, and the body fluid leakage is not easily caused. Further, since the deformation of the absorber 13 can be suppressed by the deformation, the absorption performance can be maintained. Further, in the present embodiment, the thinned portion forming region N1 extends from the front body portion M1 of the self-absorbing body 13 to the rear body portion M3, but the present invention is not limited thereto. In other words, the thinned portion forming region N1 may be formed only in the underarm portion M2. Further, the thinned portion forming region N1 may be formed only in the front piece portion M1, only in the back piece portion M3, or in the longitudinal direction end portion. Since the portion close to the waist portion is in close contact with the skin by the waist wrinkles, the wearing portion can be improved by making the hard portion of the thinned portion 501 not abut against the skin. The diaper diaper 10 of the present embodiment is formed by compressing the surface of the top sheet 14 from the surface layer of the top surface sheet 14 of the absorbent body 13 to form the thinned portion 501 having the concave portion 502. That is, the top sheet 14 is fixed in a state of being in close contact with the thinned portion 501. Thus, by compressing the top sheet 14 together, the deformation suppressing portion 402 is also formed on the top sheet 14, thereby suppressing twisting or breaking with respect to the movement during walking. As described above, when the sheet laminated on the absorbent body 13 is also compressed together to form the concave portion 502, the top sheet 14 on the absorbent body 13 is in the vicinity of the concave portion 502 by the compression. Partially sinks to the side of the absorber 13 and is integrated with the absorber 13. By the fixation of such a firm absorbent body 13 with various sheets, the twisting or offset of the absorbent body 13 is suppressed even after the front and rear movement of the legs. Fig. 7 is an enlarged view showing a part of the thinned portion 501 on the upper surface of the absorbent body 13 of the present embodiment (the thinned portion 501 of the absorber 13 surrounded by the broken line VII in Fig. 5). The thinned portion 501 can be configured by arranging a plurality of concave portions 502 at intervals L1 (i.e., discontinuously). In the present embodiment, the concave portion 502 has a quadrangular shape, for example, and can be formed by compressing the absorbent body 13 with an embossing die of the same shape. The interval L1 is about 2 mm. Moreover, the length L2 of the recess is about 2. 4 mm. Further, the width L3 of the concave portion is about 2 mm. L1, L2 and L3 are preferably in the range of 1 mm ≦ L1 ≦ 5 mm, 1 mm ≦ L2 ≦ 50 mm, and 1 mm ≦ L3 ≦ 5 mm, respectively. Furthermore, the recess 502 is a pattern representative, the number or size of which follows this range. The concave portions 502 are arranged at intervals L1, but the gap 701 between the adjacent concave portions 502 is further recessed than the deformation suppressing portion 402 surrounded by the thinned portion 501. That is, as the compression at the time of forming the concave portion 502, the absorber 13 of the gap 701 portion is stretched, and the concave portion 502 becomes more concave than the deformation suppressing portion 402. Therefore, although there is a difference in height between the concave portion 502 and the gap 701, they are lower than the uncompressed portion, and the thinned portion 501 which is lower than the deformation suppressing portion 402 as a whole is formed. In the thinned portion 501 which is formed by intermittent embossing, the compression ratio is preferably about 4 to 7 times in the portion of the concave portion 502, but is not limited to the range, and is based on the material of the absorbent body 13. Or the liquid to be absorbed, and other ranges. Thus, the thinned portion 501 can be formed by intermittent embossing. Thereby, it is possible to suppress the twisting or deformation of the absorbent body caused by the front and rear movement of the leg or the like. Further, when the embossing of the thinned portion 501 is intermittent, the thinned portion 501 itself is easily bent, and is more conformable to the body, and is easy to follow the movement of the body, thereby suppressing the hard feeling. FIG. 8 is an explanatory view of the thinned portion 501 formed on the upper surface of the absorber 13 of the present embodiment, and is enlarged in a lattice shape in the thinned portion forming region N1 surrounded by the broken line circle Q in FIG. 5 . Picture. As shown in FIG. 8, the thinning portion 501 is provided in each of four grid lines AB, BC, CD, and DA which form an oblique lattice ABCDA by orthogonally intersecting points A, B, C, and D, Further, in each of the thinned portions 501, a plurality of concave portions 502 are arranged at intervals. The concave portion 502 has a function of imparting an uneven shape to the absorbent body 13 and diffusing the liquid or the like on the absorbent body 13. Furthermore, the lattice lines AB, BC, CD, and DA in Fig. 8 are schematically represented. In the present embodiment, as an example, the concave portion 502 has a rectangular shape and can be formed by compressing the absorbent body 13 with an embossing die of the same shape. Further, it is preferable that the interval between the plurality of concave portions 502 is 1 mm to 5 mm, the length of the concave portion 502 is 1 mm to 50 mm, and the width of the concave portion 502 is in the range of 1 mm to 5 mm. As shown in FIG. 8, three recesses 502 are intermittently arranged on the line segment AB. The concave portion 502 located near the midpoint of the line segment AB is compressed to the deepest, and the vicinity of the intersection point A and the intersection point B on the line segment AB is compressed shallower than the concave portion 502. Further, the number of the concave portions 502 is not limited to three as in the present embodiment. Fig. 9 is a cross-sectional view taken along the line IX-IX of Fig. 8 formed on the upper surface of the absorbent body 13 of the present embodiment. As shown in FIG. 9, the thinned portion 501 is configured such that the concave portion 502 is intermittently arranged at a portion from the intersection point A to the intersection point B on the line segment AB. The intersection area of the grid lines AB and DA (intersection point A and its vicinity) 901 and the intersection area of the grid lines AB and BC (intersection point B and its vicinity) 902 are compressed to the shallowest, and are located in the adjacent two intersection areas 901 and 902. The recess 502 of the intermediate portion 903 is compressed the deepest. Thus, the lattice line AB is formed by a region compressed into a plurality of depths. In other words, in the present embodiment, the thinned portion 501 has a boundary that is compressed so that the depth from the surface of the front sheet side of the absorber 13 is shallower than the portion where the thinned portion 501 is the deepest. Further, in the present embodiment, the example in which the thin portion 501 is formed with the concave portion 502 intermittently is shown, but the present invention is not limited thereto. For example, the recessed portion 502 may be continuously connected to form the thinned portion 501, and the depth of the recessed portion 502 gradually becomes shallower from the central portion of the intermediate portion 903 toward the intersecting regions 901 and 902. Between the lattice lines AB, at the bottom of the recess 502 having the deepest depth of the thinned portion 501, an interlayer joint compressing portion 904 having a depth deeper than the concave portion 502 and deeper is formed intermittently. By forming the interlayer joint compressing portion 904, the absorber 13 can be integrated with the back sheet 12 superposed on the absorber 13 by compression. Further, the interlayer bonding and compressing portion 904 may be formed in one or a plurality of layers. Further, the ridge line at the upper portion of the concave portion 502 indicates the outline 905 of the portion of the non-recessed portion 502 which is seen when cut in the cross section. Next, an example of a method of processing the surface shape of the absorbent body 13 of the present embodiment will be described with reference to Figs. 8 and 9 . In the case where the oblique lattice ABCDA is formed on the upper surface of the absorber 13 of the present embodiment, the concave portions 502 are generally arranged by the embossing technique to form the lattice lines AB, BC, CD, and DA, thereby forming the oblique lattice. ABCDA. Specifically, for example, the forming roller is rotated in a direction orthogonal to the extending direction of the rotating shaft to form the concave portion 502. In Fig. 8, the extending direction of the rotating shaft of the forming roll is orthogonal to the line segment CA, and the forming roll is rotated from the intersection point C toward the intersection point A in parallel with the line segment CA (in the direction of the arrow in Fig. 8). Here, when the depth of the concave portion of the thinned portion 501 on the lattice lines AB and DA is fixed, when the forming roller approaches the intersection region 901 near the intersection A, the material on the surface of the absorber 13 gradually approaches. Intersection point A causes tension. However, in the concave portion 502 of the portion where the thinned portion 501 is formed in the present embodiment, since the depth of the intersecting region 901 is shallower than the depth of the concave portion 502 of the intermediate portion 903, the material on the surface of the absorbent body 13 can be prevented from approaching the intersection A. Thereby, in the intermediate portion 903, since the absorbent body 13 is compressed toward the back sheet 12 on the one hand, the tension is not caused in the intersection region 901, and the material of the absorbent body 13 in the vicinity of the intersection A is not broken. The flexibility of the absorbent body 13 can be improved. Further, since the hardness of the surface of the absorbent body 13 can be lowered, the wearability of the wearer can be improved, and the wearing comfort or the skin feel can be improved. Further, the shape of the thinned portion is not limited to the shape of the embodiment, and the thinned portion may be formed in a continuous line in the extending direction, or may be enlarged in the intermediate portion in the width of the cross section orthogonal to the extending direction. The intersection area is formed narrower. Further, the thinned portion may be formed as a continuous line, and the remaining portions may be formed intermittently, or the cross-sectional area of the thinned portion orthogonal to the extending direction may be changed according to a combination of the width and the change in depth. 3. (Second Embodiment of the absorbent article) Fig. 10 is an explanatory view showing a thinned portion 1001 which is formed on the upper surface of the absorbent body 13 of the second embodiment of the diaper diaper shown in Fig. 1, and 1 is an enlarged view showing one lattice shape in the thinned portion forming region N1 surrounded by the broken line circle Q in the fifth embodiment of the embodiment. The shape of the absorber 13 of the present embodiment is different from the shape of the absorber 13 of the first embodiment in that a groove portion 100 is formed in a continuous groove shape in the lattice line AB. However, a portion between the points bc of the recess 1002 is formed. Since the thinned portion 1001 is a recess portion which is located deeper between the point Ab and the point cB of the concave portion 1002 of the intersecting region. More specifically, as shown in FIG. 10, on the lattice line AB, the portion between the point Aa of the concave portion 1002 near the intersection point A and the vicinity of the intersection point B and the point dB is the shallowest, and the point and the point Aa are respectively The portion between the points ab and the point cd between the adjacent recesses 1002 between dB is relatively deep compressed. Further, a portion (intermediate region) between the points bc of the concave portion 1002 located at the central portion of the lattice line AB is compressed the deepest, and the thinned portion 1001 is formed. In other words, in the present embodiment, among the concave portions 1002 in which the lattice lines AB are continuously formed, the region between the points Ab and the region between the points cB are defined as belonging to the intersection region, and the intersection region is included between the points Aa including the intermediate region. The area between the area and the point dB, and the area between the area outside the point, that is, the area between the point ab and the point cd. Further, a portion between the points bc is the thinned portion 1001 of the present embodiment. Fig. 11 is a cross-sectional view taken along line XI-XI of Fig. 10 of the absorbent body 13 of the present embodiment. As shown in FIG. 11, in the present embodiment in which the concave portion 1002 is continuously formed from the intersection point A to the intersection point B on the line segment AB, the central region (between the points Aa) 1101 and the lattice located at the intersection of the lattice lines AB and DA are formed. The portion of the recess 1002 of the central region (between the points dB) 1102 of the intersection area of the lines AB and BC is compressed to the shallowest. The portion of the recess 1002 outside the intersection regions 1103 and 1104 (between the points ab and the dots cd) between the adjacent two central regions 1101 and 1102 is relatively deep compressed. Further, a portion of the concave portion 1002 located in the intermediate portion 1105 (between the points bc) between the outer regions 1103 and 1104 is the thinned portion 1001 that is compressed the deepest. Thus, the lattice line AB is formed by a region that is compressed stepwise into a plurality of depths. In the present embodiment, the thinned portion 1001 is formed to have the same depth and continuously formed, but the present invention is not limited thereto. For example, similarly to the first embodiment described above, the recessed portions may be intermittently arranged to form the thinned portion 1001. Moreover, the depth of the phase between the area between the points ab and the area between the points cd may be three stages or more instead of only two stages. Between the lattice lines AB, at the bottom of the intermediate portion 1105 having the deepest depth of the concave portion 1002, an interlayer joint compressing portion 1106 having a depth deeper than the intermediate portion 1105 and deeper is formed intermittently. By forming the interlayer joint compressing portion 1106, the absorber 13 and the back sheet 12 superposed on the absorber 13 can be integrated by compression. Further, the interlayer bonding and compressing portion 1106 may be formed in one or a plurality of layers. Moreover, the ridge line of the upper part of the recessed part 1002 is shown by the outline 1107 of the part of the non-thinning part 1001 seen by the cross section. In the absorber 13 of the present embodiment, since the depth of the recessed portion 1002 gradually becomes shallower toward the central regions 1101 and 1102 of the intersecting region from the intermediate portion 1105 via the intersecting region outer regions 1103 and 1104, the same manner as in the first embodiment. The material on the surface of the absorber 13 can be prevented from approaching the intersection point A. Thereby, in the outer region 1103 or the intermediate region 1105 (especially the intermediate region 1105), since the absorber 13 is compressed toward the back sheet 12, the tension does not occur in the central region 1101, so that the vicinity of the intersection A is The material of the absorbent body 13 is not broken, and the softness of the absorbent body 13 can be improved. Further, since the hardness of the surface of the absorbent body 13 can be lowered, the wearability of the wearer can be improved, and the wearing comfort or the skin feel can be improved. Here, the difference between the depths of the contour line 905 and the intermediate portion 903 of the absorber 13 of the first embodiment is small. On the other hand, in the absorber 13 of the present embodiment, the difference between the depth of the outline 1107 and the outer areas 1103 and 1004 is large, so that the absorber 13 is easily bent along the recess 1002. Thereby, in the present embodiment, the flexibility of the absorber 13 can be further improved as compared with the first embodiment. Fig. 12 is an explanatory view showing a thinned portion 1201 formed on the upper surface of the absorber 13 according to the modification of the second embodiment, and is a thinned portion forming region surrounded by a broken line circle Q in Fig. 5 of the first embodiment. One grid shape in N1 is enlarged to show a map. The shape of the absorber 13 of the present embodiment is different from the shape of the absorber 13 of the second embodiment in that a groove portion 100 is formed in a continuous groove shape in the lattice line AB. However, the thin portion 1201 between the points be Two recessed portions 1202 are formed intermittently. More specifically, as shown in FIG. 12, on the lattice line AB, the vicinity of the intersection A (between the points Aa) and the vicinity of the intersection B (between the points fB), that is, the central area of the intersection area is compressed to the shallowest, between the point Aa and The point af between adjacent points dB is compressed deeper than the central area. Further, the concave portion 1202 between the points bc on the both sides of the point between the points af on the lattice line AB and the point de is further compressed to the deepest. That is, the thinned portion 1201 of the present embodiment is provided with the recessed portion 1202 that is the deepest compressed. Fig. 13 is a cross-sectional view taken along line XIII-XIII of Fig. 12 of the absorbent body 13 of the present embodiment. As shown in FIG. 13, between the intersection A and the intersection B on the line segment AB, between the central area 1301 of the intersection area of the lattice lines AB and DA and the point Aa of the central area 1302 of the intersection area of the lattice lines AB and BC The portion between fB is compressed to the shallowest extent, and the portion between the points ab and the point ef between the outer regions 1303 and 1305 outside the intersection region between the central regions 1301 and 1302 of the adjacent two intersecting regions is relatively deep compressed. Moreover, in the middle region (between the points be) between the outer regions 1303 and 1305, on the one hand, the portion 1306 between the point bc adjacent to the outer region 1304 and the portion 1307 between the dots adjacent to the outer region 1305 are compressed. The two recesses 1202 are formed to be the deepest. On the other hand, the depth of the portion 1304 between the points cd between the recesses 1202 is relatively shallower than the recess 1202. Thus, the lattice line AB is progressively compressed into a plurality of depths, and a plurality of regions that are compressed the deepest are formed. In the present embodiment, as in the second embodiment, an example in which the groove lines are formed in a continuous groove shape is shown, but the present invention is not limited thereto. For example, only the deepest recessed portions 1202 may be intermittently arranged to form the thinned portion 1201. Also, the depth of the stage can be more than 3 stages rather than only 2 stages. Further, the area of the deepest recess 1202 may be three or more. Between the lattice lines AB, at the bottom of the concave portion 1202, interlaminar joint compression portions 1308 and 1309 which are deeper than the depth of the concave portion 1202 and deeper are formed intermittently. By forming the interlayer joint compressing portions 1308 and 1309, the absorber 13 and the back sheet 12 superposed on the absorber 13 can be integrated by compression. Further, the interlayer bonding compression portions 1308 and 1309 may be formed separately or in plural. Further, the ridge line of the upper portion of the concave portion 1202 is shown as a contour line 1310 of a portion of the non-thinned portion 1201 which is seen when cut in a cross section. In the absorber 13 of the present embodiment, since the depth of the continuous concave portion (groove) on the grid line gradually becomes shallower toward the central regions 1301 and 1302 of the intersection region from the intermediate portion via the intersection region outer regions 1303 and 1305, Similarly to the first and second embodiments, it is possible to prevent the material on the surface of the absorber 13 from approaching the intersection point A. Thereby, in the outer region 1303 or the thinned portion region 1307 (particularly, the regions 1306 and 1307), since the absorber 13 is compressed toward the back sheet 12, the center region 1301 does not cause tightness, so the intersection point The material of the absorbent body 13 near A is not broken, and the softness of the absorbent body 13 can be improved. Further, since the hardness of the surface of the absorbent body 13 can be lowered, the wearability of the wearer can be improved, and the wearing comfort or the skin feel can be improved. Further, in the absorbent body 13 of the present embodiment, since the thinned portion is formed into a wave shape which is easily bent by forming the deepest concave portion 1202 in the thinned portion, the flexibility of the absorbent body 13 can be further improved. The absorbent body of the present invention may be coated with a hydrophilic sheet (such as a core material) and compressed together with the hydrophilic sheet to form a concave portion. Further, the absorbent body, the hydrophilic sheet, and the top sheet may be collectively compressed from the surface of the top sheet to form a concave portion. Further, the shape of the concave portion is not limited to the rectangular shape, and various shapes can be used. For example, circles, ellipses, squares, triangles, and the like. In any of these arbitrary shapes, a thinned portion may be formed on the surface of the absorber. Further, in the above-described embodiment, the numerical values such as the width or the depth of each concave portion are measured based on the vicinity of the center of the vicinity of the maximum width or depth of each concave portion. In this way, the principle of the numerical value such as the width or the depth of each concave portion is a value measured based on the vicinity of the center of each concave portion. However, when the shape of each concave portion is complicated, the other portions of the concave portions may be used as the width or The basis for the measurement of the value such as depth. In addition to the above effects, the present invention can improve the diffusing property of the liquid on the surface of the absorber by using the oblique lattice shape, thereby improving the utilization efficiency of the absorber and reducing the cost. Further, the forms of the absorber 13 according to the first to third embodiments of the present invention may be combined with each other. 4. In the third embodiment of the absorbent article, the absorbent article according to the third embodiment of the present invention will be described in detail with reference to Figs. 14 to 21 . The third embodiment of the present invention can also be applied to the diaper-type diaper shown in Fig. 1 of the first embodiment, and the same configuration as that of the first or second embodiment is shown in Figs. 14 to 21 . The corresponding parts are marked with the same symbol. Fig. 14 is a plan view of the diaper-type diaper according to the embodiment as seen from the skin contact surface side, and corresponds to a state in which the diaper shown in Fig. 1 is unfolded. Fig. 15 is a cross-sectional view showing the broken line of Fig. 14 taken along the line XV-XV, and Fig. 16 is an exploded perspective view showing the diaper type diaper shown in Fig. 14. Further, Fig. 17 is a partial plan view showing a portion where the absorbent body 3013 and the top sheet 14 of the present embodiment are located from the side of the top sheet 14, and Fig. 18 is a view showing a pattern of the oblique pattern of the embossed pattern of Fig. 17. Sexual top view. The absorber 3013 of the present embodiment is basically made of the same material as the first and second embodiments. The absorbent body 3013 has an elongated shape so as to extend over the front piece, the underarm, and the back piece. Further, when divided into three parts of the front piece portion M1, the crotch portion M2, and the back piece portion M3, the left and right portions M2 are compared with the left and right pair of leg-opening portions 10L surrounding the thigh portions of the legs. One of the pair of notches 3013a is formed in an arc shape. Further, the notch portion 3013a may not be formed depending on the size of the absorber 3013. Further, the absorber 3013 of the present embodiment is an hourglass type in which the width of the center portion is narrower than the front and rear ends, but the shape of the absorber of the present invention is not limited thereto. If the front body portion is in the front-rear (up and down) direction from the front body portion and the direction orthogonal thereto is the left-right direction, for example, the corners of the front and rear (upper and lower) ends are cut into a circle, and the front and rear (up and down) are used. The shape of the elliptical shape, the round shape, and the length of the front and rear (up and down) are equal to each other. This point is also the same in the case where the notch portion is provided in the first and second embodiments described above. Further, as shown in FIG. 17 and FIG. 18, the diaper 10 has a thinned portion forming region (embossed pattern forming region) N1 which is compressed by regular embossing from the surface of the top sheet 14 toward the absorber 3013. . In the thinned portion forming region N1, an embossed pattern having a pattern that is substantially obliquely latticed is formed by the arrangement of the plurality of recessed portions 3021 and 3023 formed by compression. Specifically, the concave portion 3023 (hereinafter also referred to as "first concave portion" or "short concave portion") located at the intersection of the lattices and the concave portion 3021 located between the concave portions 3023 are provided (corresponding to the provisions of the present invention) The thinned portion has a continuous long groove shape, and is also referred to as a "second concave portion" or a "long concave portion" in the present embodiment. That is, the plurality of rows are formed by alternately arranging the concave portion 3021 and the concave portion 3023 into the compressed row 3022, and by arranging the plurality of rows of the compressed rows 3022, the lattice-shaped embossed pattern extending obliquely is formed. Although not shown in the drawing, the concave portion 3021 is formed by collectively compressing the core material and the absorbent body 3013 from the surface of the top sheet 14. The long recessed portion 3021 of the present embodiment is inclined with respect to the imaginary line P along the central axis of the wearer's body when the diaper is worn. Specifically, the long concave portion 3021 is provided with a rightward long concave portion 3021a that is inclined at a specific angle α with respect to the imaginary line P in the first direction, that is, in the right direction in the drawing, and is inclined at a specific angle β in the second direction, that is, in the left direction in the drawing. The leftwardward long recess 3021b. Further, as shown in FIG. 7, the long concave portion 3021 and the short concave portion 3023 which are inclined in the same direction are disposed so as to alternately vacate the specific interval L1. As shown in FIG. 17, the row in which the rightward long recessed portion 3021a is arranged is referred to as a first compressed row 3022a, and the row in which the left elongated recessed portion 3021b is arranged is referred to as a second compressed row 3022b. These compression lines 3022 are linearly inclined with respect to the imaginary line P at the same angle as the inclination angle of the long concave portion 3021. Further, the plurality of rows of first compressed rows 3022a are arranged in parallel with each other at an interval S1. Further, the plurality of rows of second compressed rows 3022b are arranged in parallel with each other at an interval S2. Further, the interval S1 between the rows 3022 and the interval L1 between the rows of the recesses 3021 and 3023 is determined such that the short concave portion 3023 is located at the intersection of the first compressed row 3022a and the second compressed row 3022b. In this manner, by arranging the plurality of rows of the first compressed row 3022a and the second compressed row 3022b, the embossed pattern in which the short concave portions 3023 are located at the intersection point in the diagonal lattice shape is formed. In the present embodiment, the intervals S1 and S2 are the same value, but they may be different values. Further, as can be understood from Fig. 17 and Fig. 18, one of the lattices (squares) has the following constitution. The four sides are formed by the respective long recesses 3021, and the four apexes are formed by the short recesses 3023. Here, the length of the long recess 21 is shorter than the previous intervals S1, S2. As shown in FIG. 17, at the lattice point, the rightward long concave portion 3021a and the left long long concave portion 3021b do not overlap. In other words, in the present embodiment, the non-overlapping region is defined as an intersection region, and the intersection region is a region including the central portion of the short concave portion 3023 and the outer short portion 3023 and the outer concave portion 3021. Further, as shown in FIG. 17, the embossed pattern is not formed at both ends of the absorber 3013. Therefore, the absorber 3013 is a compression portion non-formation region (embossed pattern non-formation region) N2 located on both sides of the compression portion formation region (emboss pattern formation region) N1. This is to prevent the body fluid from leaking from the leg-opening portion 10L along the embossed pattern. Fig. 19 is a schematic enlarged view of the vicinity of the intersection of the compressed lines of Fig. 18, and Fig. 20 is a view showing a section based on the line XX-XX of Fig. 19. Fig. 21 is a view showing a section based on the XXI-XXI line of Fig. 19. As shown in FIG. 19, a region indicated by a broken line surrounding the long recessed portion 3021 and the periphery of the short recessed portion 3023 is a quasi-compressed region 3024. That is, in order to form the long recessed portion 3021 and the short recessed portion 3023, the top sheet 14 and the absorber 3013 are directly compressed to a greater extent, whereby the top sheet 14 and the absorber 3013 around the long recess 3021 and the short recess 3023 are Stretched and indirectly compressed. The region which is thus strongly compressed by the embossing die, that is, the slightly compressed region around the concave portion is referred to as a quasi-compression region 3024. Therefore, the compressed region of the absorber 3013 or the like, that is, the compressed region becomes the respective concave portions 3021 and 3023, and the quasi-compression region 3024 around them. Further, the regions other than the compressed regions in the absorber 3013 or the like are not compressed, but become uncompressed regions. In other words, the vicinity of the intersection point 3026 which is the outer side region between the short concave portion 3023 and the long concave portion 3021 which is the intersection of the lattice, and the main absorption region 3025 which is the inside of the lattice, are the uncompressed regions. As shown in FIGS. 20 and 21, the unabsorbed region, that is, the main absorption region 3025 is the same as the thickness (height) of the absorber 3013 or the like in the vicinity of the intersection portion 3026. On the other hand, the long recessed portion 3021 and the short recessed portion 3023 are compressed by the absorber 3013 and the like, and are more recessed than the uncompressed region. Further, a portion where the uncompressed region and each of the concave portions 3021 and 3023 are connected and the thickness of the absorbent body 3013 gradually changes is a quasi-compression region 3024. Next, the shape of each concave portion will be specifically described. As shown in FIG. 19 and FIG. 20, the long recessed portion 3021 is formed by the long recessed portion first portion 3211 having the outer shape and the recessed portion first portion 3211 and the longer recessed portion first portion 3211. The circular long recessed portion second portion 3212 is formed. The long recessed portion first portion 3211 is elongated as the length U and the width V shorter than the lengths S1 and S2 of the side of the lattice as shown in FIG. Specifically, the two ends have a circular arc shape. Further, inside the long recessed portion first portion 3211, a circular long recessed portion second portion 3212 is disposed so as to be staggered at a predetermined interval with respect to the longitudinal center axis. The long recessed portion second portion 3212 has a longer recessed portion first portion 3211 that is recessed deeper in the thickness direction of the absorber. As shown in FIG. 20, in the long recessed portion 3021, the long recessed portion second portion 3212 is located at the deepest point, and the long recessed portion first portion 3211 is located slightly raised from the bottom of the long recessed portion second portion 3212. When the depth to the deepest position of the long concave portion 3021, that is, the depth of the bottom portion of the long concave portion second portion 3212 is Q1, and the depth to the bottom portion of the long concave portion first portion 3211 is Q2, the difference of Q2 is subtracted from Q1. That is, Q3 is about 3. The depth Q1 to the bottom of the second portion 3212 of the long recess. 5 to 15% or so. Moreover, if the thickness of the absorber 3013 and the top sheet 14 in the uncompressed region is Q4, the depth Q1 to the bottom of the second portion 3212 of the long recess is 42. 5%~97. About 5%. Further, the depth Q2 to the bottom of the first recess 3211 of the long recess is 37 of the thickness Q4. 5% to 95. 0% or so. As described above, the long recessed portion 3021 of the present embodiment is formed by compressing the absorber 3013 to an extremely deep position. Moreover, it has a shape having a depth of two stages. On the other hand, as shown in FIG. 9, the short recessed portion 3023 located at the intersection of the lattices is formed by compressing the absorber 3013 or the like to have the same depth Q2 as the long recessed portion first portion 3211. The embossing process for forming the long concave portion 3021 and the short concave portion 3023 is such that an adhesive is interposed between the top sheet 14 and the absorbent body 3013, and the top sheet 14 and the absorbent body 3013 are compressed together from the surface of the top sheet 14. . The long recessed portion 3021 and the short recessed portion 3023 are formed by compressing the top sheet 14 and the absorber 3013 from the surface of the top sheet 14 by a specific mold formed on the embossing roll. Further, in the long recessed portion 3021, the second recessed portion 3212 is a small circle having a small area. Therefore, in the pressing by the embossing roller, the pressure is concentrated on the second recess portion 3212, and the absorber 13 and the top sheet 14 are strongly compressed. At the time of this compression, the pulp fibers of the absorbent body 3013 are firmly entangled with the fibers of the top sheet 14, and joined together in a state in which they are integrated. Next, the first pressing portion 3211 of the long recess portion also applies the same pressing force at the time of compression, but the area is wide, and accordingly, the pressure does not concentrate as the second recess portion 3212 of the long recessed portion. Therefore, the engagement of the absorber 3013 with the top sheet 14 is slightly weaker than the long recess portion 212, but is sufficient to form the recess shape. As described above, in the second concave portion 3212 of the elongate portion, the absorber 3013 is strongly compressed, and the absorber 3013 is firmly joined to the top sheet 14, thereby maintaining the shape of the long recess 3021. For example, even when the wearer sits down and the like, and the pressure caused by the weight of the wearer is applied to the surface of the absorbent body 3013, the long concave portion 21 does not slack and maintain its shape. Further, even if the diaper 10 is strongly stretched by various activities of the legs, the top sheet 14 and the absorbent body 3013 are firmly joined, and the long recess 3021 maintains its shape. Here, it is also possible to form a two-stage structure in which the long recessed portion first portion 3211 and the long recessed portion second portion 3212 are not provided, and a strong compressive force is applied to the entire long recessed portion 3021. That is, in the embossing process, it is also possible to consider the inside of the substantially elliptical protrusion of the first recessed portion 1311 of the long recessed portion, and further compress the mold of the substantially elliptical projection having a gentle surface instead of making the control long recessed portion Two 3212 round protrusions protrude from the mold. However, since a portion where the pressure is concentrated cannot be produced by such a mold, if a strong pressure is not applied as a whole, a portion where the fibers of the front sheet and the absorber are joined in a state of being strongly entangled cannot be produced. As a result, the pressing force required becomes very strong, and there is a case where the top sheet 14 is broken. Further, in the compression by the weak pressing force as a whole, it is difficult to form the long recess 3021 which can withstand the weight of the wearer or various activities. In the present embodiment, the embossing die is provided with a projection corresponding to the second recessed portion 3212, and the portion of the top sheet 14 and the absorber 3013 is firmly joined by locally compressing to a greater extent. Moreover, the occurrence of defects such as cracking of the top sheet 14 at the time of manufacture is prevented. Further, depending on the strength or the amount of compression of the top sheet 14, the compression line may be formed by intermittently arranging the dot-like recesses or the like without using such a two-stage compression structure. Further, the short concave portion 3023 provided at the intersection of the lattices is formed by pressing the absorbent body 3013 and the long recessed portion first portion 3211 to the same extent as described above by the embossing roller. The strength of the pressing is such that the top sheet 14 does not break, and the strength of the joining of the top sheet 14 to one of the absorbent bodies 3013 is achieved. As shown in FIG. 20 and FIG. 21, in the absorber 3013, the bottom surface portion of the long recessed portion second portion 3212 is the high-density portion 3013A having the highest density of the absorber. Further, the uncompressed region such as the main absorption region 3025 and the vicinity of the intersection portion 3026 is the low density portion 3013D having the lowest density of the absorbent body. Further, the bottom surface portion of the long recessed portion first portion 3211 and the bottom portion of the short recessed portion 3023 are the medium density portion 3013B. The quasi-compression region 3024 is a density changing portion 3013C whose density gradually decreases toward the uncompressed region. Here, the absorbent body 3013 mainly contains SAP and pulp as described above, and the density is mainly related to the density of the pulp fibers. Therefore, the high-density portion 3013A is in a state in which the pulp is compressed and the gap between the pulps is small. On the other hand, the low-density portion 3013D is in a state in which the gap between the pulps is larger than the high-density portion 3013A. Further, since the concave portions 3021 and 3023 are formed by compressively joining the top sheet 14 which is a synthetic fiber and the absorbent body 3013 whose main component is pulp, the bottom surfaces of the concave portions 3021 and 3023 are formed into a film shape and are regarded as substantially non-absorbent. liquid. Therefore, the body fluid discharged to the concave portions 3021 and 3023 is absorbed by the density changing portion 3013C which is the side wall of the concave portions 3021 and 3023, and is transported to the main absorption region 3025. As described above, in the present embodiment, when the compressed row 3022 is formed, the recesses 3021 and 3023 are not formed as continuous recesses, and the recesses 3021 and 3023 are intermittently arranged. In particular, the short concave portion 23 is provided at the intersection of the oblique lattice, and the next long concave portion 3021 is located away from the intersection. The reason why the interval L1 is set in this way will be described below. As described above, the compressed row 3022 of the oblique lattice is formed by pressing the embossing roll having the molds facing the concave portions 3021 and 3023 on the surface while rotating. As shown in Fig. 18, when the embossing roller rotates one side and travels in the direction of the arrow W, all of the long recessed portions 3021 are arranged in a direction orthogonal to the traveling direction W of the embossing roller (parallel to the direction of the rotating shaft). At the same time being pressed. In the present embodiment, the size of the embossing roller is determined such that the circumference of the embossing roller corresponds to the length of the absorbent body 3013 in the longitudinal direction, but the invention is not limited thereto. Further, in the present embodiment, the traveling direction W of the embossing roller is perpendicular to the rotation axis of the embossing roller, and when the diaper 10 is completed, it is parallel to the direction of the previous imaginary line P. As described above, after the top sheet 14 and the absorber 3013 are compressed together by the embossing roll, the other sheets and the like which are required are laminated and the like, and cut into the size of the diaper 10. Since the cutting is performed over the length of the front piece, the underarm, and the back piece of the diaper 10, the traveling direction W of the embossing roll can be made parallel to the imaginary line P to form an imaginary line P. An oblique embossed plaid pattern. Therefore, the rightward long concave portion 3021a is also inclined to the right direction with respect to the traveling direction W, and the leftward long concave portion 3021b is inclined to the left direction. Therefore, as the embossing roller travels in the traveling direction W, the distance between the rightward long concave portion 3021a and the leftward long concave portion 3021b which are adjacent to the intersecting portion 3023 is gradually shortened. Here, the top sheet 14 is introduced into the recesses 3021, 3023 at the time of pressing the embossing rolls forming the recesses 3021, 3023. In particular, since the long concave portion 3021 is disposed adjacent to the left long concave portion 3021a and the left long concave portion 3021b, the top sheet 14 is introduced from the left and right at the same timing. That is, in Fig. 18, the top sheet 14 is stretched by simultaneously applying the introduction force indicated by the arrow A to the left and right. Since the shorter the distance between the adjacent rightward concave portion 3021a and the leftward concave portion 3021b, the less the margin of the top sheet 14 relative to the drawing force A is stretched, the top sheet 14 gradually becomes a highly tight state. For example, if it is assumed that a grid of the same size is produced, a pattern in which the rightward long recessed portion 3021a and the leftwardly elongated recessed portion 3021b are joined at the intersection of the lattices without forming the space L1 is formed, and the rightward long concave portion is formed near the corner of the lattice. The 3021a is disposed in close proximity to the left long recess 3021b. In this way, in the vicinity of the intersection, the density of the absorber 3013 itself is relatively high and is in a relatively hard state, and in addition, the top sheet 14 is highly tight due to the introduction force of the elongated recesses 3021a, 3021b. The absorber 3013 is in contact. In the main absorption region 25 near the intersection, the SAP in the absorbent body 3013 abuts against the top sheet 14, and becomes a rough feeling. This is not good because it is irritating to the wearer's skin. Therefore, in the present embodiment, the top sheet 14 is not placed in a state of being highly tight by not compressing the distance between the adjacent long recesses 3021 so as not to reach the vicinity of the intersection 3026 of the specific distance T. That is, the compression of the absorbent body 3013 and the engagement of the absorbent body 3013 with the top sheet 14 are limited to a range in which the top sheet 14 in the main absorbent region 3025 can be maintained in a margined state. Thereby, the feeling of the unevenness due to SAP and the corner portion of the lattice are suppressed from being hardened. In other words, as shown in FIG. 18 and FIG. 19, the shortest distance between the rightward long concave portion 3021a and the left long concave portion 3021b is T, and the long concave portion 3021 is formed only in a portion where the distance between the two is longer than T. . Therefore, the top sheet 14 is fixed in a soft state, and a hard touch can be avoided. In the figure, although the distance T is referred to as a direction orthogonal to the traveling direction W, the direction parallel to the traveling direction W is also caused by the problem that the corner portion is hardened, so it is preferable to equally separate the fixed distance. As described above, each of the long recessed portions 3021 is formed. In the present embodiment, since the lengths of the rightward long recessed portion 3021a and the leftwardly elongated recessed portion 3021b are made equal, and the interval L1 is also made equal, the distance parallel to the traveling direction W is also equally spaced. Each of the long recesses 3021 is formed above T. In other words, when the embossed pattern is determined, the distance between the adjacent concave portions becomes T in a direction parallel to the diagonal line of the quadrilateral (division) formed by the first compressed row 3022a and the second compressed row 3022b. In the above manner, the arrangement interval of each of the long recessed portions 3021 is determined. Further, as described above, since the introduction force A acts strongly against the direction orthogonal to the traveling direction W of the embossing roller, it can be said that the diagonal is parallel with respect to the traveling direction W of the embossing roller, even if adjacent The distance between the recesses is slightly shorter than T, and the influence is also small. For example, in the case where the thickness of the absorber is 8 mm and the depth Q2 of the first recess is 6 mm, the T is about 7 mm. It also varies depending on the relationship between the amount of SAP in the absorbent body 3013 and the amount of pulp fibers, or the thickness of the top sheet 14. An important point in the present invention is that when an embossed pattern having a diagonally-shaped lattice-like component is used, an embossed pattern is not formed in a portion where the interval between adjacent concave portions is narrowed. On the other hand, since the intersection of the lattices is not close to each other and the left and right sides are simultaneously pressed, the top sheet 14 is not strongly stretched. If the tension of the top sheet 14 is considered, and in the compressed row 3022, the interval in which the recess is not formed is too wide, there is a possibility that the compressed line 3022 cannot be recognized as a line, and the lattice cannot be recognized. Further, when the interval between the long recessed portions 3021 is too wide, it is difficult for the absorber 3013 to exhibit an effect of tending to follow the movement of the body and to bend obliquely. Therefore, the concave portion 3023 is provided without affecting the intersection of the tension of the top sheet 14, and the visibility of the lattice is improved, thereby further enhancing the visual effect of the embossed pattern. Further, it is not necessary to make the corner of the grid square hard, and the absorber 3013 is a person who can easily follow the movement of the body and bend. As described above, in the present embodiment, the shortest distance between the adjacent concave portions 3021 does not become less than T. In other words, the embossing pattern in which the concave portion 3021 is separated by a distance T or more, that is, the embossed pattern in which the embossing process is not performed in the vicinity of the intersection 3022 of the lattice, prevents the skin contact feeling on the skin contact surface from becoming hard. Moreover, since the corner of the lattice is in a soft state similar to the main absorption region 3025, even if an oblique plaque pattern is used, the corner of the lattice square does not become a hard and sharp hand, and the wearer can be softened. Skin feels. Further, at the intersection of the first compressed row 3022a and the second compressed row 3022b, by providing the short concave portion 3023, the intersection of the lattices (the vertices of the squares) is made clear, thereby improving the aesthetics and design. Further, the obliquely extending compressed row 3022 is not mistaken for wrinkles caused by defective manufacturing, or irregularly arranged recesses or the like. Moreover, the inclination direction of the absorber 3013 which follows the activity of the body is also easily deformed. Further, in the present embodiment, the embossing process is described for the use of the embossing roller, but the method is not limited to this method, and the embossed plate of the size of the diaper may be pressed in the size of the diaper. Embossed and so on. Next, the details of the embossed pattern formed by embossing will be described. As shown in Fig. 18, in the embossing pattern of the present embodiment, the first compressed row 3022a is formed by arranging the rightward long concave portion 3021a and the short concave portion 3023 located before and after the longitudinal direction of the rightward long concave portion 3021a. Similarly, the left long concave portion 3021b is formed with a gap L1 from the short concave portion 3023 to form a second compressed row 3022b. In the above, the first compressed row 3022a is arranged in parallel with the plurality of rows at intervals S1, and the second compressed row 3022b is arranged in parallel with the plurality of rows at intervals S2. Further, as shown in the figure, the first compressed row 3022a and the second compressed row 3022b form an embossed pattern having a diagonal lattice shape as viewed from the figure. The lengths S1 and S2 of one side of the lattice of the present embodiment are equal to 27. 0 mm. The spacing between the grids is preferably 13. 0 mm or more 54. 0 mm or less. Moreover, the length U of the long recess 3021 in the longitudinal direction is 19. 0 mm, and the length U is preferably 55% to 85% of the length S1, S2 of one side of the lattice. Moreover, the width V of the long recess 3021 is 3. 0 mm. The width V is preferably 2. 0 mm or more, 4. 0 mm or less. Further, the width V1 of the short concave portion 3023 is the same as or narrower than the width V of the long concave portion 21. In the present embodiment, the width V1 is 2. 0 mm. The width V1 is preferably 1. 0 mm or more, 4. 0 mm or less. Moreover, the interval L1 between the recesses 3021 and 3023 is 4. 4 mm. The interval L1 is preferably 2. 0 mm or more 6. 0 mm or less. By setting this relationship, the distance T between the adjacent long recesses 3021 is less than 6. The portion of 0 mm is in a state of no recess. Further, in the present embodiment, the thickness of the absorbent body 3013 and the top sheet 14 before the embossing is 8. 0 mm, as shown in Fig. 8, the depth Q1 of the deepest portion of the long recess 3021 is 7. 8 mm. And, the depth Q2 of the second deep part is 7. 5 mm. Moreover, the thickness Q4 of the uncompressed region is 8. 0 mm. Furthermore, the thickness of the absorber 3013 and the top sheet 14 before the embossing is preferably 5. 0 mm~20. 0 mm. Moreover, the maximum depth Q1 of the portion compressed by the recess 3021 is preferably 3. 0 mm~8. 0 mm. Moreover, the difference Q3 from the second deep portion is preferably 0. 1 mm to 0. 5 mm. Further, the thickness (height) Q4 of the uncompressed region is preferably 5. 0 mm~20. 0 mm. By forming each of the concave portions 3021 and 3023 at such a depth and space, even if the weight is applied, the thinned portion can be maintained, and the skin contact surface on the lower portion of the diaper can maintain a soft touch. Therefore, by embossing the embossed pattern in a lattice shape, it is possible to suppress deformation of the diaper due to various movements of the leg, and to make the skin feel soft, and to suppress the irritation to the skin as much as possible. Further, in the present embodiment, the long recessed portion 3021 is defined by the elongated elliptical long recessed portion first portion 3211. However, the present invention is not limited thereto, and a plurality of dots or parallelograms may be intermittently arranged. The concave portion is formed to form a compressed row in a diagonal lattice shape. In other words, in the present embodiment, it is important that the vicinity of the intersection portion 3026 where the concave portion is not formed is provided only in a specific size, and the shape of the concave portion defined by the long concave portion 21 constituting each side of the lattice is not limited to this embodiment. form. The same effect can be obtained by arranging the above plurality of points and the like. In this case, the concave portion is also disposed such that the distance between the adjacent concave portions in the direction parallel to the diagonal of the square of the lattice is T or more. Further, in the present embodiment, one or more of the long recesses 3021 and the one long recesses 3021 may be formed by shortening the length in the longitudinal direction.

That is, any shape can be used as long as it is a shape suitable for recognizing the apex (corner) of the square of the lattice. 5. In the fourth embodiment of the absorbent article, an embodiment of the absorbent article of the present invention will be described in detail with reference to Figs. 22 to 29 . The fourth embodiment of the present invention can also be applied to the diaper-type diaper shown in Fig. 1 of the first embodiment, and the same configuration as that of the first to third embodiments is shown in Figs. 22 to 29 . The corresponding parts are marked with the same symbol. Fig. 22 is a plan view of the diaper-type diaper according to the embodiment as seen from the skin contact surface side, and corresponds to a state in which the diaper shown in Fig. 1 is unfolded. Fig. 23 is a broken sectional view taken along line XXIII-XXIII of Fig. 22, and Fig. 24 is an exploded perspective view showing the diaper diaper shown in Fig. 22. Further, Fig. 25 is a partial plan view showing a portion where the absorbent body 4013 and the top sheet 14 of the present embodiment are located from the side of the top sheet 14, and Fig. 26 is a view showing an oblique pattern of the embossed pattern in Fig. 25. Modeal partial top view. The absorber 4013 of the present embodiment is basically basically made of the same material as the first and second embodiments. Further, the shape of the absorber 4013 is similar to that of the absorber 3013 of the third embodiment, and is divided into three parts of the front body piece portion M1, the crotch portion M2, and the back body piece portion M3, and is surrounded by the armpit portion M2. The left and right pair of leg-opening portions 10L of the thigh portions of the two legs are formed with one of the arc-shaped notch portions 4013a. Further, as shown in FIG. 25 and FIG. 26, the diaper diaper 10 has a compression portion forming region (embossed pattern forming region) which is compressed by the regular embossing process from the surface of the top sheet 14 toward the absorber 4013. N1. A plurality of concave portions 4021 formed by compression are formed in the compressed portion forming region N1, and a plurality of line compressed rows 4022 which are patterned in a diagonal lattice shape by the arrangement of the concave portions are formed. The concave portion 4021 of the present embodiment is inclined with respect to the imaginary line P along the central axis of the wearer's body when the diaper is worn. Specifically, the concave portion 4021 is provided with a long groove-shaped rightward concave portion 4021a that is inclined at a specific angle α toward the first direction, that is, in the right direction in the drawing, with respect to the imaginary line P, and is oriented to the second direction at a specific angle β, that is, left in the figure. The leftward recessed portion 4021b having a long groove shape which is inclined in the direction (hereinafter, when it is not necessary to distinguish the same, it is collectively referred to by reference numeral 4021). Further, the concave portions 4021 which are inclined in the same direction are arranged so as to form a row at a predetermined interval L1, and an embossed pattern having a lattice shape in which each of them is obliquely extended is formed. In other words, each of the recessed portions 4021 of the present embodiment corresponds to the thinned portion defined by the present invention, and corresponds to the elongated recessed portion 3021 of the third embodiment. Although not shown in the drawing, the concave portion 4021 is formed by collectively compressing the core material and the absorbent body 13 from the surface of the top sheet 14. Further, as shown in FIG. 25, the embossed pattern is not formed at both ends of the absorber 4013. Therefore, the absorber 13 is a compression portion non-formation region (embossed pattern non-formation region) N2 located on both sides of the compression portion formation region (emboss pattern formation region) N1. This is to prevent the body fluid from leaking from the leg-opening portion 10L along the embossed pattern. As shown in FIG. 25, the row in which the rightward concave portion 4021a is arranged is referred to as a first compressed row 4022a, and the row in which the left concave portion 4021a is arranged is referred to as a second compressed row 4022b (hereinafter, when it is not necessary to distinguish the same, the symbol 4022 is used) Unified reference). These compression lines 4022 are linearly inclined with respect to the imaginary line P at the same angle as the inclination angle of the concave portion 4021. The plurality of rows of first compressed rows 4022a are arranged in parallel with each other at an interval S1. Further, the plurality of rows of the second compressed rows 4022b are arranged in parallel with each other at an interval S2. In this manner, by arranging the plurality of rows of the first compressed row 4022a and the second compressed row 4022b, an embossed pattern having an oblique lattice shape is formed. In the present embodiment, the intervals S1 and S2 are also set to the same value, but they may be different values. Further, as can be understood from Fig. 25, each of the concave portions 4021 is a length that can form a square based on the lattice. Here, the length of the recess 4021 is shorter than the previous intervals S1, S2. That is, as described above, the plurality of concave portions 4021 are formed by arranging the specific interval L1 to form the compressed row 4022, but the length of the concave portion and the lattice are determined so that the concave portion is not located at the intersection portion 4023 of the lattice. Therefore, the rightward concave portion 4021a and the leftward concave portion 4021a do not overlap, and the top sheet 14 and the absorbent body 13 which are formed by the concave portion 4021 in the intersecting region 4023 are uncompressed. Similarly, even in the main absorption region 4025 which is an inner region of the square formed by the respective recess portions 4021, the top sheet 14 and the absorber 4013 are uncompressed. In other words, in the present embodiment, the region that does not overlap the rightward concave portion 4021a and the leftward concave portion 4021a corresponding to the thinned portion is defined as the intersection region 4023, and the intersection region 4023 becomes the uncompressed region. Fig. 27 is a schematic enlarged view of the vicinity of the intersection of the compressed lines in Fig. 26, and Fig. 28 is a view showing a section based on the line XXVIII-XXVIII of Fig. 7. Figure 29 is a view showing a section based on the line XXIX-XXIX of Figure 7; As shown in FIG. 27 and FIG. 28, the recessed portion 4021 is formed by a first recessed portion 4211 having an outer shape, and a second recessed portion 4212 which is disposed in the first recessed portion 4211 intermittently and further recessed further than the first recessed portion 4211. Composition. As shown in FIG. 27, the first recessed portion 4211 is a shorter length U and a shorter width V than the lengths S1 and S2 of the side of the lattice. Specifically, the two ends have a circular arc shape. Further, inside the first recessed portion 4211, the circular second recessed portions 4212 are arranged at a predetermined interval with respect to the central axis in the longitudinal direction. The second recess 4212 is recessed deeper in the thickness direction of the absorber 4013 than the first recess 4211. As shown in FIG. 28, in the recessed portion 4021, the second recessed portion 4212 is located at the deepest point, and the first recessed portion 4211 is located slightly raised from the bottom of the second recessed portion 4212. The depth to the deepest position of the concave portion 4021, that is, the depth of the bottom of the second concave portion 4212 is Q1, and the depth to the bottom of the first concave portion 4211 is Q2, and the difference Q2 from Q1, that is, Q3, and the uncompressed region are subtracted from Q1. The relationship between the thickness of the absorbent body 4013 and the top sheet 14 is the same as that of the third embodiment. In addition, the embossing process for forming the concave portion 4021 can be performed in the same manner as in the third embodiment, and the same effect as the case where the long concave portion 3021 is formed as in the third embodiment can be obtained. Further, in FIG. 27, a region indicated by a broken line surrounding the periphery of the concave portion 4021 is referred to as a quasi-compression region 4024. That is, in order to form the concave portion 4021, the top sheet 14 and the absorbent body 4013 are strongly compressed, whereby the top sheet 14 and the absorbent body 4013 around the concave portion 4021 are compressed by being stretched. Therefore, the quasi-compression region 4024 is a region in which the absorber 13 is indirectly compressed, compared to an uncompressed region such as the intersection region 4023 or the main absorption region 4025. As shown in Fig. 28, in the absorber 4013, the bottom surface portion of the second recessed portion 4212 is the high-density portion 4013A having the highest density of the absorber. Further, the uncompressed region such as the main absorption region 4025 is the low density portion 4013D having the lowest absorbent density. Further, the bottom surface portion of the first recess 4211 is the medium density portion 4013B. The quasi-compression region 4024 is a density changing portion 4013C whose density gradually decreases toward the uncompressed region. Here, the absorbent body 4013 mainly contains SAP and pulp as described above, and the density is mainly related to the density of the pulp fibers. Therefore, on the other hand, the high-density portion 4013A is in a state in which the pulp is compressed and the gap between the pulps is small. On the other hand, the low-density portion 4013D is in a state in which the gap between the pulps is larger than the high-density portion 4013A. Further, since the concave portion 4021 is formed by compression-bonding the top sheet 14 of the synthetic fiber together with the absorbent member 4013 whose main component is pulp, the bottom surface of the concave portion 4021 is formed into a film shape and is considered to be substantially non-absorbent. Therefore, the body fluid discharged to the concave portion 4021 is absorbed by the density changing portion 4013C which is the side wall of the concave portion 21, and is transported to the main absorption region 4025. Next, in the present embodiment, the concave portion 4021 is not provided in the intersection region 4023 in the oblique lattice-shaped embossed pattern. That is, the concave portion 4021 as the thinned portion has a boundary at the intersection region 4023. As in the third embodiment described above, the concave portion 4021 is formed by pressing and pressing the embossing roller having the mold having the control concave portion 4021 formed on the surface thereof. As shown in Fig. 26, when the embossing roller rotates in one direction and faces in the direction of the arrow W, all the portions of the concave portion 4021 arranged in the direction orthogonal to the traveling direction W of the embossing roller are simultaneously pressed. In the present embodiment, the size of the embossing roller is determined such that the circumference of the embossing roller corresponds to the length of the absorbent body 4013 in the longitudinal direction, but the invention is not limited thereto. Also in the present embodiment, as in the third embodiment, the traveling direction W of the embossing roller is parallel to the direction of the previous imaginary line P when the diaper 10 is completed. In the third embodiment, as described above, after the top sheet 14 and the absorber 13 are collectively compressed by an embossing roll, the other sheets required are laminated, etc., and cut into diapers. 10 size. Since the cutting is performed over the length of the front piece, the underarm, and the back piece of the diaper 10, the traveling direction W of the embossing roll can be made parallel to the imaginary line P to form an imaginary line P. An oblique embossed plaid pattern. Further, the interval L1 between the rightward concave portion 4021a and the leftward concave portion 4021b formed by this, the shortest distance T, and the inclination with respect to the traveling direction W are also the same as those described for the long concave portion 3021 in the third embodiment. Therefore, the description is omitted. In this embodiment, the shortest distance between adjacent recesses 4021 does not fall below T. In other words, the embossing pattern in which the concave portion 4021 is disposed at a distance equal to or greater than the distance T, that is, the embossed pattern in which the embossing is not performed in the vicinity of the intersection of the lattice, prevents the skin contact feeling on the skin contact surface from becoming hard. Further, since the corner of the lattice is as soft as the main absorption region 4025, even if an oblique embossed pattern is used, the corner of the lattice does not become a firm and sharp hand, so that the wearer can be softened. sense. Therefore, the intersection region 4023 between the first compressed row 4022a and the second compressed row 4022b is an uncompressed region in which the concave portion 4021 is not provided, and the corner of the lattice does not become a hard sharp, and the absorber of the intersecting region 4023 The thickness and height of the 4013 are the same as those of the main absorption region 4025. Therefore, even if an oblique embossed pattern is formed, the skin abutting surface of the diaper 10 gives the wearer a soft feeling of the whole skin, and the corner portion of the lattice does not irritate the skin. Further, in the present embodiment, the embossing is not limited to the use of an embossing roll, and the embossing plate or the like may be used to press the embossing unit in the size of the diaper by the embossed plate having the size of the diaper. Further, the embossing pattern formed by the embossing is substantially the same as that described in the third embodiment with respect to the long recess 3021 or the compressed rows 3021a and 3021b. In the present embodiment, the lengths S1 and S2 of one side of the lattice are equal to 27. 0 mm. The spacing between the grids is preferably 13. 0 mm or more 54. 0 mm or less. Moreover, the length U of the concave portion 4021 in the longitudinal direction is preferably about 55% to about 90% of the length S1 and S2 of one side of the lattice. In the present embodiment, the length U is 19. 0 mm. Moreover, the width V of the recess 4021 is 3. 0 mm. The width V is preferably 2. 0 mm or more, 4. 0 mm or less. Moreover, the interval L1 between the recesses 4021 is 8. 8 mm. The interval L1 is preferably 4. 0 mm or more 12. 0 mm or less. By setting this relationship, the distance T between the adjacent recesses 21 is less than 6. The portion of 0 mm is in a state of no recess. Further, in the present embodiment, the thickness of the absorber 4013 and the top sheet 14 before the embossing is 8. 0 mm, as shown in Fig. 28, the depth Q1 of the deepest portion of the recess 21 is 7. 8 mm. And, the depth Q2 of the second deep part is 7. 5 mm. Moreover, the thickness Q4 of the uncompressed region is 8. 0 mm. Further, the thickness of the absorber 4013 and the top sheet 14 before the embossing, the maximum depth Q1 of the portion compressed by the recess 4021, and the difference Q3 between the portions deeper than the second portion may be the same as in the third embodiment. The range is selected so that the same effect can be obtained. In addition, the shape or arrangement of the concave portion 4021, the first concave portion 4211, and the second concave portion 4212 of the present embodiment can be appropriately determined as described in the third embodiment with respect to the long concave portion 3021. 6. The fifth embodiment of the absorbent article, and the embodiment of the manufacturing apparatus and the manufacturing method thereof, will be described in detail with reference to Figs. 1 to 14 and a fifth embodiment of the absorbent article of the present invention, a manufacturing apparatus and a manufacturing method thereof. . In the present embodiment, the "concave portion" is referred to as a thinned portion formed by compressing the absorber by embossing. The portion in which the concave portion is formed in the absorber has high compression and high density as compared with the other portion. Further, when the density of the portion where the concave portion is formed is the same as the other portion, the thickness of the portion where the concave portion is formed is also the same as the other portion. The absorbent article of the present embodiment is configured such that it is formed in a region where a plurality of concave portions on the side of the top sheet of the absorbent body intersect, and the back sheet side of the region is raised. In other words, the concave portion of the present embodiment has a configuration in which the lattices are uniform. However, the concave portion has a raised portion on the side of the back sheet, and the intersection portion of the top sheet side is recessed and the thinned portion is defined by the intersection portion. . According to this configuration, the rigidity is reduced in the vicinity of the region where the plurality of concave portions intersect, and as a result, it is easy to bend in the region, and the conformability can be improved. Furthermore, when the surface of the absorber on the top sheet side is used as a reference, the depth of the recess of the intersection region can be formed in a manner consistent with the depth of the concave portion of the thinned portion (ie, a groove having a uniform depth along the lattice). , can also be formed in an inconsistent manner (for example, in a shallow manner). First, an embodiment in which the present invention is applied to a disposable unfolded diaper (hereinafter, "expanded diaper" or simply "diaper" in the present embodiment) will be described below. <Structure> Fig. 30 is a perspective view showing the appearance of an example of the diaper according to the embodiment of the present invention as seen from the front side. The diaper 5010 of the present embodiment is an unfolded diaper, and has a front body region 5010F, a back body region 5010R, and a crotch region 5010C that connects the front body region 5010F and the back body region 5010R. Further, a waist opening portion 5010W that surrounds the waist of the wearer in the front body region 5010F and the back body region 5010R at the time of wearing is formed. Similarly, a pair of right and left leg-opening portions 5010L of the calf portion in which the lower portion of the front body region 5010F and the rear body region 5010R and the underarm region 5010C surround the legs of the wearer are formed. The front body region 5010F is located on the ventral side of the wearer when worn, and the back body region 5010R is located on the back side of the wearer. Further, the underarm region 5010C covers the underarm of the wearer when worn, and the wearer's legs pass through the pair of left and right leg-opening portions 5010L. Therefore, the leg-opening portion 5010L is located at any position from the root portion of the wearer's legs to the vicinity of the calf. The imaginary line P is extended from the ventral side toward the back side through the crotch portion in the central portion of the diaper. Specifically, the imaginary line P is, for example, such that the waist side of the unfolded diaper is defined as the upper side and the lower side of the underarm is defined as the lower side, and extends along the surface of the diaper in the up and down direction, and also via the underarm portion and the back side. Extend in the up and down direction. The left and right end edges of the body sheet region 5010R on the outer side of the cover sheet 5011 on the outer side of the unfolded diaper 5010 are then joined to the left and right end edges of the front body panel region 5010F when worn, and are connected to form legs. A pair of left and right fastening tapes 5010A are formed around the opening 5010L. The adhesive tape 5010A is attached to the cover sheet 5011 next to the front sheet region 10F before the patch sheet 5010B can be peeled off. Fig. 31 is a schematic exploded perspective view of the unfolded diaper 10 shown in Fig. 30, and Fig. 32 is a schematic plan view of the diaper 5010 in an extended state according to an embodiment of the present invention viewed from the side of the top sheet 14. The absorbent body 5013 of Fig. 31 and the unfolded diaper 5010 of Fig. 32 each show a state of partial breakage for convenience of explanation. As shown in Fig. 31, the unfolded diaper 5010 of the present embodiment has a laminated structure in which a cover sheet 5011 formed of a thin non-woven fabric in order to obtain a good hand is superposed on the outer layer, and has a liquid-impermeable property. The bottom sheet (back sheet) 5012, the elongated absorbent body 5013, the liquid permeable top sheet (front sheet) 5014, and the water-repellent sheet member constitute one of the three-dimensional wrinkles (side sheets) Material) 5015. On the left and right sides of the crotch region 5010C of the cover sheet 5011, a pair of notch portions 5011N which are one of the leg-opening portions 5010L are formed. Between the cover sheet 5011 and the pair of three-dimensional gathers 5015, one of the leg gather wrinkles is formed to extend the rubber line 5016 in an extended state. The back sheet 5012 is bonded to the cover sheet 5011, and the absorber 5013 is disposed between the back sheet 5012 and the top sheet 5014, and the top sheet 5014 is joined to the back sheet 5012 via the absorber 5013. Further, in an area corresponding to the upper end portion of the back sheet region 5010R among the back sheet members 5012, an elastic sheet extending in the width direction of the back sheet member 5012 and imparting a moderate wearing feeling to the wearer is bonded to the wearer. Material 5010D. The absorbent body 5013 of the present embodiment, which is located under the top sheet 5014, is covered with a cushion member (core material) 5018 such as a tissue or a nonwoven fabric to cover the cushion body mainly comprising the absorbent body 5017 of the pulp and SAP. In the present embodiment, the absorber main body 5017 is made of SAP, but in the present invention, it may be a case where SAP is not included. The seam formed by coating the absorbent body 5017 by the covering member 5018 is formed, for example, as shown in FIG. 31, on the upper surface of the absorbent body 5013 and extending in the longitudinal direction. The absorbent body 5013 of the present embodiment has an elongated shape so as to extend over the front body piece, the underarm, and the back body piece. Here, when the front body portion is set to the front-rear (up and down) direction, and the direction orthogonal thereto is the left-right direction, the absorber 5013 of the present embodiment has different lengths from front to back (up and down). The rectangle is (in FIGS. 31 and 32, the length of the front and rear (upper and lower) is longer than the length of the left and right). Further, the shape of the absorber 5013 of the present embodiment is not limited thereto, and includes, for example, a substantially square shape in which the lengths of the front and rear (up and down) are equal to each other, and the corners of the front and rear (upper and lower) ends are cut into a circle, before and after (before and after (before and after) Up and down) various shapes such as an elliptical shape and a round shape. Further, in the crotch portion of the absorber 5013, one of the arc-shaped notch portions may be formed so as to correspond to the pair of leg-opening portions 5010L. In the present embodiment, as shown in FIG. 32, a plurality of concave portions 5020 are continuously formed on the surface of the absorber 5013 and arranged in an oblique lattice shape. By continuously forming the recess 5020, air can pass through the ventral side or the back side, thereby ensuring gas permeability. Further, in the present embodiment, in the region where the plurality of concave portions 5020 intersect, the absorbing body 5013 is provided with a ridge portion so as to be swelled on the side of the back sheet 5012 of the region (see reference numeral 5021 in Fig. 33 below). The recesses 5020 and the ridges are formed by, for example, sandwiching the compression absorbers 5013 by two rollers that rotate (see FIG. 37 below). The pair of three-dimensional gathers 5015 are provided along the longitudinal direction of the absorber 5013 and extend along the longitudinal direction of the absorber 5013, and one side edge portion has a substantially linear shape, and the other side edge portion is in the side edge portion. A notch portion 5015N is formed in the vicinity of the lower side. The inner portion of the pair of three-dimensional gathers 5015 is in a non-joined state with respect to the top sheet 5014, and the three-dimensional gathers 5015 include free ends at the side edges of the substantially straight shape. At the free end of the three-dimensional gathers 5015, as shown in Fig. 32, a rubber thread 5019 which is an elastic member that exerts a tensile force is disposed in an extended state along the longitudinal direction of the absorbent body 5013. The pair of three-dimensional gathers 5015 can be erected along the both side edges of the absorber 5013 in the worn state by the rubber thread 5019. <Concave portion and ridge portion> Fig. 33 is a schematic view showing a cross section taken along line XXXIII-XXXIII of Fig. 32. The section line of the XXXIII-XXXIII direction is drawn in the center of the area where the plurality of recesses 5020 intersect in FIG. That is, the two recesses 5020 shown in FIG. 33 mean the area where the plurality of recesses 5020 intersect. Figure 34 is a schematic view showing a cross section taken along the line XXXIV-XXXIV in Figure 32. The section line of the XXXIV-XXXIV direction is drawn in FIG. 32 by the position where the area intersected by the plurality of recesses 5020 deviates. That is, the four recesses 5020 shown in FIG. 34 are those in which the plurality of recesses 5020 do not intersect. Fig. 35 is a schematic view showing a cross section taken along the line XXXV-XXXV in Fig. 32; Moreover, Fig. 36 is a schematic plan view of the absorber 5013 viewed from the side of the top sheet 5014 in the present embodiment. The solid line shown in FIG. 36 indicates the concave portion 5020, and a plurality of dot-shaped hatched areas indicate the raised portion 5021. The broken line shown in FIG. 36 is drawn in the longitudinal direction of the absorber 5013 so as to include the plurality of raised portions 5021, and corresponds to the "recessed portion 5041 of the second roller 5040" described in FIG. 37 described below. . As shown in FIG. 33, a raised portion 5021 is formed at a position below the region where the plurality of concave portions 5020 intersect, and on the side of the back sheet 5012 of the absorber 5013. That is, the raised portion 5021 is formed in the region where the plurality of recesses 5020 intersect, and is formed on the side of the back sheet 5012 of the absorber 5013 corresponding to the region. In the present embodiment, the raised portion 5021 corresponds to the first concave portion 5020a or the second portion other than the intersection region of the absorbent sheet 5013 corresponding to the region where the first concave portion 5020a and the second concave portion 5020b intersect. The side of the back sheet 5012 of the absorber 5013 of the recess 5020b is formed in a more bulging manner. Here, the side of the back sheet 5012 of the absorber 5013 corresponding to the first recess 5020a or the second recess 5020b other than the intersection area is an absorber 5013 corresponding to a region where the plurality of recesses 5020 do not intersect as shown in FIG. The bottom sheet 5012 side. It can be seen that the surface of the bottom sheet 5012 side of the absorbent body 5013 below the recess 5020 shown in Fig. 33 is more swelled than the surface of the bottom sheet 5012 side of the absorbent body 5013 below the recess 5020 shown in Fig. 34. Since the ridge portion 5021 is formed by the region where the plurality of recesses 5020 intersect, the degree of compression in the portion of the absorber 5013 is small, so that the bonding of the pulp or the SAP becomes weak, and as a result, the absorber 5013 is in the plurality of recesses 5020. The area of the intersection is easily bent, and the feeling of the diaper 10 can be improved. In the present embodiment, the bulging of the raised portion 5021 is formed so as to protrude toward the outer side of the unfolded diaper 5010 as shown in Fig. 33. However, the present invention is not limited thereto. If the raised portion 5021 is formed so as to be raised with respect to the surface corresponding to the bottom of the concave portion 5020 other than the intersecting region, the raised portion 5021 may not be formed to protrude toward the outer side of the diaper 5010. For example, the surface of the back surface sheet 5012 of the absorber 5013 corresponding to the region where the plurality of recesses 5020 do not intersect is recessed inward with respect to the diaper 5010. Further, in the present embodiment, the raised portion 5021 is formed at least in a region where the plurality of concave portions 5020 intersect. In the present invention, the ridge portion 5021 may be formed on the side of the back sheet 5012 of the absorber 5013 corresponding to the first recess 5020a or the second recess 5020b other than the intersecting region. According to this configuration, the bottom portion of the concave portion 5020 other than the region intersecting the absorbent body 5013 is softened, so that the feeling of wearing can be further improved. The thickness of the thinnest portion of the covering member 5018 corresponding to the bottom of the recess 5020 is 0. 1 mm to 1. 0 mm is preferable for effectively exerting the effects of the present invention. Further, the thickness of the region of the absorber 5013 corresponding to the recess 5020 in which the raised portion 5021 is formed is preferably thicker than the thickness of the thinnest portion. 1 mm to 1. 0 mm and 0. 2 mm to 0. 4 mm is more effective in effectively exerting the effects of the present invention. In this case, the basis weight of the absorbent body (absorbent pad) 5017 in which SAP and pulp are mixed is 170 g/m. 2 ~600 g/m 2 More suitable and is 240 g/m 2 ~530 g/m 2 More suitable (the basis weight of pulp is 80 g/m 2 ~300 g/m 2 More suitable and is 160 g/m 2 ~240 g/m 2 more suitable). 36, on the side of the top sheet 5014 of the absorber 5013, as shown in FIG. 36, the first recess 5020a extending in the first direction is formed, and the first recess 5020a is crossed and the first direction is formed with respect to the first recess 5020a. The second recess 5020b extends in the second direction. Further, the first concave portion 5020a and the second concave portion 5020b are each formed of a plurality of thinned portions arranged in parallel with each other. Further, as shown in FIG. 36, the raised portion 5021 is formed on the side of the back sheet 5012 of the absorber 5013 corresponding to the region where the first recess 5020a and the second recess 5020b intersect, with respect to the first recess 5020a or the first portion. 2 The surface of the bottom of the recess 5020b is formed in a more bulging manner. In the present embodiment, the concave portion 5020 is formed in a strip shape along the longitudinal direction of the absorbent body 5013 (upward and downward direction in Fig. 36), and is not formed at the end in the width direction (left-right direction in Fig. 36) of the absorbent body 13. unit. A region in which the concave portion 5020 is formed in the absorber 13 is referred to as a concave portion forming region N1, and a region in which both ends of the absorbent body 5013 in the width direction of the concave portion 5020 are not formed is referred to as a concave portion non-formation region N2. In the present embodiment, the concave portion non-formation region N2 is provided. However, the present invention is not limited to this embodiment, and of course, the concave portion 5020 may be provided to the end portion of the absorber 5013. Therefore, the present invention may be configured not to provide the recess non-formation region N2. Further, the present invention allows the concave portion 5020 to be formed not to the end portion of the longitudinal direction of the absorbent body 5013 (the upper and lower directions in FIG. 36) or to be formed to the end portion. In the case of forming to the end portion, the gas permeability and the suffocation can be improved. In the present embodiment, the recess 5020 is extended from the first recess 5020a that extends obliquely toward one side (toward the right side in FIG. 36) in the width direction of the absorber 5013, and extends to the other side (toward the left side in FIG. 36). The second recess 5020b is configured. The position of the imaginary line P on the absorber 5013 is extended from the upper end of the front body portion toward the lower end of the back body portion. Specifically, as shown in FIG. 36, when the absorber 5013 has an elongated shape, it is extended in the longitudinal direction. The recess 5020 extends obliquely with respect to the imaginary line P. In other words, the first concave portion 5020a is inclined at one angle by one angle with respect to the direction along the side of the imaginary line P, for example, the longitudinal direction, and the second concave portion 5020b is inclined at the angle β toward the other side. The angle α and the angle β may be the same or different. Further, in Fig. 36, the plurality of first recesses 5020a are inclined at the same angle and arranged at regular intervals. In other words, each of the first recesses 5020a is arranged in parallel at a fixed interval. However, the present invention is not limited thereto, and the interval between the recesses 5020 is not fixed, or the inclination angles of the recesses 5020 are different. The second recess 5020b is also the same. Further, in the present embodiment, as shown in Fig. 36, the raised portion 5021 has at least a pair of parallel contours, and the plurality of raised portions 5021 are aligned in an oblique lattice and are formed in parallel with each other. Further, by having the ridge portion 5021 having a parallel contour, the absorber 5013 can be easily bent at the contour portion. Therefore, by determining the contour shape of the raised portion 5021, the meandering portion of the absorbent body 5013 can be arbitrarily set. According to the configuration of the diaper 5010 of the present embodiment, the flexibility is improved in the region where the plurality of concave portions intersect, and the absorbent body 5013 is easily bent in the plurality of concave portions, so that the adaptability of the diaper 5010 can be improved. 37 is a view for explaining a state in which the compression absorber 5013 is sandwiched between two rolls according to an embodiment of the present invention, and FIGS. 38A and 38B are cross-sectional views when the compression member is sandwiched by the convex portion 5031 and the recess portion 5041. 38A is the MD direction (the traveling direction), and FIG. 38B is the CD direction (the width direction). The cross-sections of FIGS. 38A and 38B are cut so as to pass through the central portion of the region where the plurality of recesses 5020 intersect. That is, the recesses 5020 shown in FIGS. 38A and 38B respectively indicate the areas where the plurality of recesses 5020 intersect. The manufacturing apparatus 5100 of the diaper 5010 of the present embodiment is configured to include a first roller (first rotating member) 5030 and a second roller (second rotating member) 5040 that rotates together with the first roller 5030. The first roller 5030 has a peripheral surface portion on which the convex portion 5031 is formed, and abuts against the surface of the top sheet 5014 of the absorber 5013. The second roller 5040 has a peripheral surface portion on which the recessed portion 5041 is formed, and abuts against the surface of the bottom sheet 5012 of the absorber 5013. In other words, the absorber 5013 is formed by the first roller 5030 and the second roller 5040 rotating together and sandwiched between the rollers to form an embossed pattern. The convex portion 5031 includes a first convex portion 5031a configured to form the first concave portion 5020a, and extending in a third direction corresponding to the first direction (the direction in which the first concave portion 5020a is formed in FIG. 36); And the second convex portion 5031b is configured to form the second concave portion 5020b, and is in a second direction different from the third direction in a state of intersecting with the first convex portion 5031a (shown in FIG. 36). The fourth direction in which the second recess 5020b is formed extends in the fourth direction. The recessed portion 5041 is disposed in the second roller 5040 at a position corresponding to a region where the first convex portion 5031a and the second convex portion 5031b intersect. In the present embodiment, the depressed portion 5041 is formed by a plurality of recesses arranged in parallel with each other. Therefore, since the recessed portion 5041 has a simple structure, it can be easily formed on the second roller 5040. In order to effectively exhibit the effect of the present invention, in the relationship between the convex portion 5031 of the first roller 5030 and the depressed portion 5041 of the second roller 5040, the height (thickness) of the convex portion 5031 in the radial direction of the first roller 5030 is preferably It is from 2 mm to 20 mm, and more preferably from 5 mm to 10 mm. Further, the depth of the depressed portion 5041 in the radial direction of the second roller 5040 is preferably from 0.05 mm to 5 mm, more preferably from 0.1 mm to 0.5 mm. The diaper 5010 of the present embodiment is produced, for example, by the following manufacturing method or a manufacturing apparatus for carrying out the method. First, the absorbent body 5017 composed of pulp and SAP is coated by the covering member 5018 to produce a continuous cushion-shaped absorbent body 5013. Then, as shown in FIG. 37, the first roller 5030 rotates in the B direction and the second roller 5040 rotates in the C direction, and the continuous absorber 5013 that flows from the upstream direction in the MD direction in the A direction is sandwiched, and the continuous absorber 5013 is continuous. The absorber 5013 is subjected to embossing. By the embossing, the concave portion 5020 and the raised portion 5021 are formed in the continuous absorbent body 5013. Specifically, the first roll 5030 compresses the side of the top sheet 5014 of the continuous absorbent body 5013 so that the first recess 5020a and the second recess 5020b are formed, and at the same time, by the second roll 5040 The embossed portion 5021 is formed on the side of the back sheet 5012 of the absorber 5013 corresponding to the region where the first recess 5020a and the second recess 5020b intersect, and the back sheet 5012 side of the continuous absorber 5013 is deformed. In other words, the intersection of the lattice line, that is, the recess 5020, allows the absorber 5013 to be deformed into the recess 5041 of the second roller 5040, so that compression does not occur even if it is pressed from the first roller 5030 (that is, it does not become high density), or Substantially no compression is produced. Next, the continuous absorbent body 5013 after the embossing is flowed downstream of the MD direction, and cut by the cutting device for the length required for each diaper portion, and the top sheet 5014 and the bottom sheet 5012 are used. After the cover sheets 5011 and the like are joined, the diaper 10 is manufactured. In the present embodiment, the concave portion 5020 and the raised portion 5021 are formed by compressing the absorbent main body 5017 and the covering member 5018. However, the present invention is not limited thereto. For example, the absorbent body 5017, the covering member 5018 (that is, the absorbent body 5013) and the top sheet 5014 may be laminated (see FIG. 39 below) or the absorbent body 5017 may be compressed. The concave portion 5020 and the raised portion 5021 are formed. In the case where only the absorbent body 5017 is compressed, the person who does not include SAP may also be used for the absorbent body 5017. When the absorber 5013 and the top sheet 5014 are laminated, it is also possible to compress the absorber 5013 which is previously separated (for example, cut) and the top sheet 5014. Fig. 39 is a schematic cross-sectional view showing the MD direction in the case where the compression absorber 5013 and the top sheet 5014 are sandwiched by two rolls in another embodiment of the present invention. The top sheet 5014 is continuous as shown in FIG. Each of the plurality of absorbers 5013 is laminated in advance and formed into a mat shape, and is divided into a portion of one diaper 10. A plurality of absorbers 5013, as shown in FIG. 39, are vacant at regular intervals, respectively (for example, following) the continuous topsheet 5014. As shown in FIG. 39, the plurality of absorbers 5013 and the top sheet 5014 are stacked in the direction A, and the first roll 5030 and the second roll 5040 of the manufacturing apparatus 5100 are sandwiched in the same manner as in the above embodiment. Hold compression. Thereby, the absorber 5013 is sandwiched and compressed together with the top sheet 5014, and the absorbent body 13 and the top sheet 5014 are laminated to form the concave portion 5020 and the raised portion 5021. After the compressed absorbent body 5013 and the top sheet 5014, the back sheet 5102, the cover sheet 5011 and the like are bonded and cut to a desired length to produce one diaper 10. Further, in the present embodiment, the ridge portion 5021 is provided on the back sheet 5012 side of the absorber 5013 by the first roll 5030 and the second roll 5040, but the present invention is not limited thereto. For example, the ridge portion 5021 may be provided by suctioning the side of the back sheet 5012 of the absorber 5013. The fifth embodiment described above can be appropriately changed or changed. For example, the structure of the diaper of the present invention is not limited to the above-described expanded type, and may be any configuration as long as it is a diaper comprising the absorbent article as defined in the patent application. For example, the present invention can be applied even to a diaper-type diaper as shown in Fig. 1, or another urine pad. Further, in the above-described embodiment, the plurality of concave portions 5020 are continuously formed on the surface of the absorber 5013 to form an oblique grid-like array pattern, but the invention is not limited thereto. In the present invention, as long as a plurality of recessed portions 5020 intersect with each other, for example, a plurality of recesses 5020 may be intermittently formed on the surface of the absorber 5013, and the arrangement pattern of the recesses 5020 may be a polygon such as a triangle or a hexagon. The arrangement pattern, various arrangement patterns such as a linear, curved, or wavy pattern. In the above embodiment, the top sheet 5014, the absorber 5013, the back sheet 5012, and the cover sheet 5011 are joined to the entire surface of the recess 5020 and the raised portion 5021. However, in the present invention, the sheet may be partially joined. In the above embodiment, the heights of the first convex portion 5031a and the second convex portion 5031b are equal to each other, that is, the depths of the bottom portions of the first concave portion 5020a and the second concave portion 5020b are equal, but the present invention is not equal. The effect of softening the area where a plurality of concave portions intersect is exerted. The depth of the plurality of depressed portions 5041 or the height of the raised portions of the plurality of raised portions 5021 may be the same, and may be unequal. Further, in the above-described embodiment, the shape or the respective patterns of the raised portion 5021, the convex portion 5031, and the depressed portion 5041 shown in FIGS. 33 to 39 are not limited, and the present invention may include the following modifications. 40A and 40B are plan views showing two examples of the convex portion pattern on the surface of the first roller 5030, wherein FIG. 40A shows a pattern in a diagonal lattice shape, and FIG. 40B shows a vertical and horizontal lattice pattern. 41A to 41D are plan views showing an example of a depressed portion pattern on the surface of the second roller 5040, and FIG. 41A shows a stripe pattern in the longitudinal direction (the circumferential direction of the second roller 5040), and FIG. 41B shows a pattern of a checkerboard pattern. 41C shows that the rhombuses are arranged neatly in a diagonal grid pattern, and FIG. 41D shows a pattern in which the positive directions are arranged neatly in a vertical and horizontal grid pattern. 42A to 42F are views showing an example of a raised portion pattern formed on the absorber 5013, wherein Fig. 42A shows a pattern in which the butterfly shapes are arranged in an oblique lattice shape, and Fig. 42B shows a pattern in which the obliquely continuous cross is continuous, Fig. 42C Fig. 42D shows a pattern in which the rhombuses are arranged neatly in a diagonal lattice pattern, Fig. 42D shows a pattern in which the positive direction is neatly arranged in a vertical and horizontal grid pattern, and Fig. 42F shows that the X shapes are arranged neatly in an oblique direction. Grid-like pattern. 40A and 40B, the convex portion 5031 is indicated by a dotted line, and the concave portion 5041 is indicated by a hatching in the form of a mesh in FIGS. 41A to 41D, and a plurality of oblique lines are formed in FIGS. 42A to 42F. The line indicates the ridge 5021. 40A, 41A, and 42A are patterns similar to those of the above embodiment. In addition, the region where the first convex portion 5031a and the second convex portion 5031b intersect with each other is disposed so as to correspond to the concave portion 5041, and the first roller 5030 and the second roller 5040 overlap each other when rotating. The rotation of the two rollers is synchronized. The convex portion pattern formed on the surface of the first roller 5030, the depressed portion pattern formed on the surface of the second roller 5040, and the raised portion pattern formed on the absorber 13 can be various shapes and can be variously combined. For example, when the first roller 5030 having the convex portion pattern shown in FIG. 40A and the second roller 5040 having the concave portion pattern shown in FIG. 41B sandwich the absorbent body 5013, the absorbent body 5013 is formed as shown in FIG. 42B. The raised portion 5021 of the pattern is substantially obliquely crossed. The shape of the raised portion 5021 is such that, in addition to the raised portion 5021 formed in the region where the plurality of concave portions 5020 intersect, the raised portion 5021 is formed in the region where the plurality of concave portions 5020 do not intersect, and the plurality of concave portions 5021 are formed. The area where the recesses 5020 do not intersect also increases the flexibility, so that the conformability can be further improved. When the first roller 5030 having the convex portion pattern shown in FIG. 40A and the second roller 5040 having the concave portion pattern shown in FIG. 41C sandwich the absorbent body 5013, the absorbent body 5013 is formed as shown in FIG. 42C. A raised portion 5021 of a diamond pattern is shown. Further, when the first roller 5030 having the convex portion pattern shown in FIG. 40B and the second roller 5040 having the concave portion pattern shown in FIG. 41A sandwich the absorbent body 5013, the absorbent body 5013 is formed as shown in FIG. 42D. A raised portion 5021 of a vertical stripe pattern is shown. The shape of the raised portion 5021 is such that, in addition to the raised portion 5021 formed in the region where the plurality of concave portions 5020 intersect, the raised portion 5021 is formed in the region where the plurality of concave portions 5020 do not intersect, thereby forming the raised portion 5021. The effect illustrated in Fig. 42B. When the first roller 5030 having the convex portion pattern shown in FIG. 40B and the second roller 5040 having the concave portion pattern shown in FIG. 41D sandwich the absorbent body 5013, the absorbent body 5013 is formed as shown in FIG. 42E. A raised portion 5021 of the square pattern shown. Further, when the first roller 5030 having the convex portion pattern shown in FIG. 40A is used to sandwich the absorber 5013, if the widths of the plurality of depressed portions 5041 of FIG. 41A are respectively widened, the absorber 5013 is used. A ridge 5021 is formed in an X-shaped pattern as shown in Fig. 42F. In the present invention, of course, it is not limited to the above-described patterns or combinations. Further, examples of the convex portion pattern on the surface of the first roller 5030 include a stripe pattern in the horizontal direction (CD direction) or the oblique direction, a pattern in which a curve is used, and the like. This point is also the same for the recess pattern. Further, in FIGS. 42A to 42F, the raised portion 5021 is formed by a straight line, but may be a curved line within a range in which the effects of the present invention can be obtained. Further, each of the plurality of raised portions 5021 has the same shape or size (area), but may be different in the present invention. For example, a large ridge 5021 may be provided at a portion where the absorber 5013 is to be largely bent. The portion to be largely bent is, for example, a boundary line between the side of the underarm region 5010C (leg side) where the absorbent body 5013 is to be pocket-shaped, the underarm region 5010C and the back body region 5010R (back side). The portion, the boundary line portion of the underarm region 5010C and the front body region 5010F (ventral side), the waist circumference to be deformed along the curve of the wearer's body, and the like. Further, in the above embodiment, the cross-sectional shape of the depressed portion 5041 shown in Figs. 38A and 38B is not limited, and the present invention may be changed as follows. 43A and 43B are views showing two examples of the cross-sectional shape of the depressed portion 5041, wherein FIG. 43A shows a trapezoidal shape, and FIG. 43B shows a concave portion in which the side wall has two stages. Fig. 43A is a cross-sectional view of a depressed portion 5041 similar to that of the above embodiment. Even if the depressed portion 5041 is sandwiched between the depressed portion 5041 having the recessed portion having the side wall and the convex portion 5031, the depressed portion 5041 can be formed in the same manner as in the above embodiment, so that flexibility can be obtained in the region where the concave portion intersects.
