吸收性物品 Absorbent articles

本發明是關於吸收性物品。 The present invention relates to absorbent articles.

就吸收性物品來說，已知有例如如專利文件1，具有：在液透過性薄片與液不透過性薄片之間具備吸收性芯，且沿著縱向的吸收性本體；以及沿著橫向的腰帶部，從腰圍開口部的橫方向中心朝向兩側腿圍開口部呈傾斜狀，將腰帶部的兩端部結合在吸收性本體，而形成一個腰圍開口部、與一對的腿圍開口部者。這樣的吸收性物品，吸收性本體具有：在液透過性薄片與液不透過性薄片之間存在吸收性芯的區域、以及僅由在薄片之間吸收性芯不存在的薄片所形成的區域。 As for absorbent articles, for example, Patent Document 1 is known, which has: an absorbent core provided between a liquid-permeable sheet and a liquid-impermeable sheet, and an absorbent body along the longitudinal direction; and an absorbent body along the transverse direction. The waistband is inclined from the center of the waist opening in the horizontal direction to the leg openings on both sides. The two ends of the waistband are joined to the absorbent body to form a waist opening and a pair of leg openings By. In such an absorbent article, the absorbent body has an area where an absorbent core exists between the liquid-permeable sheet and the liquid-impermeable sheet, and an area formed only by the sheet where the absorbent core does not exist between the sheets.

上述的吸收性物品，因為將腰帶部的兩端部傾斜狀結合在吸收性本體，所以在吸收性本體沒有配置伸縮性構件等。亦即，在薄片間存在吸收性芯的區域與在薄片間吸收性芯不存在的區域沒有配置伸縮性構件等。因此，在吸收性本體與穿用者的身體之間容易產生間隙。再者，在前述區域的邊界周邊，亦即，在吸收性芯的上端周邊，若吸收性芯柔軟則其本身容易變形，或因為吸收性芯存在的區域與不存在的區域的厚度不同等，薄片容易彎折或變形，在吸收性芯的上端周邊會出現皺紋、或吸收性芯的輪廓浮出的情況。這麼一來，會有***物從皺紋漏出，或外觀降低的情況。 In the above-mentioned absorbent article, since the both ends of the waistband portion are joined to the absorbent body in an oblique manner, no stretchable member or the like is arranged in the absorbent body. That is, the stretchable member etc. are not arrange|positioned in the area|region where the absorptive core exists between the sheets and the area|region where the absorptive core does not exist between the sheets. Therefore, a gap is easily generated between the absorbent body and the wearer's body. Furthermore, around the boundary of the aforementioned area, that is, around the upper end of the absorbent core, if the absorbent core is soft, it is easy to deform, or because the thickness of the area where the absorbent core exists is different from the area where it does not exist, etc. The sheet is easily bent or deformed, and wrinkles may appear around the upper end of the absorbent core, or the outline of the absorbent core may appear. As a result, excrement may leak from the wrinkles, or the appearance may decrease.

本發明，是有鑑於上述這樣的問題而研發者，作為其目的之處，是在提供抑制來自皺紋的***物的漏出、外觀降低的吸收性物品。 The present invention was developed in view of the above-mentioned problems, and its purpose is to provide an absorbent article that suppresses the leakage of excrement from wrinkles and reduces the appearance.

In particular, the reinforcing sheet is arranged on the skin side more than the absorbent core. When the reinforcing means compresses the upper end of the absorbent core to increase the average density, the reinforcing sheet can be used to cover the part of the absorbent core hardened by compression, which can further reduce wearing Discomfort at times.

這樣的吸收性物品，其中，設有前述補強手段的區域的下端較前述補強薄片的下端更位在前述縱向的下方側。 In such an absorbent article, the lower end of the region where the reinforcing means is provided is positioned on the lower side of the longitudinal direction than the lower end of the reinforcing sheet.

根據這樣的吸收性物品，可讓吸收性芯的上端部周邊剛性產生複數變化，可減低穿用時的不舒適感。 According to such an absorbent article, the rigidity around the upper end of the absorbent core can be changed in multiple ways, and the discomfort during wearing can be reduced.

這樣的吸收性物品，其中，前述補強薄片的下端與前述一對的接合部的下端一致、或較前述一對的接合部的下端更位在前述縱向的上方側。 In such an absorbent article, the lower end of the reinforcing sheet coincides with the lower end of the pair of joint parts, or is positioned on the upper side of the longitudinal direction than the lower end of the pair of joint parts.

根據這樣的吸收性物品，可抑制補強薄片阻礙穿用者的腳的動作。 According to such an absorbent article, it is possible to prevent the reinforcing sheet from hindering the movement of the wearer's foot.

這樣的吸收性物品，其中，前述補強薄片的前述橫向的末端與前述吸收性芯的前述橫向的末端一致、或較前述吸收性芯的前述橫向的末端更位於前述橫向的外側。 In such an absorbent article, the end in the transverse direction of the reinforcing sheet coincides with the end in the transverse direction of the absorbent core or is located outside the transverse end of the absorbent core.

根據這樣的吸收性物品，藉由補強薄片在吸收性芯的橫向全域使吸收性芯的上端周邊的剛性提高。因此，吸收性芯的上端周邊更加不易彎折不易變形，並容易維持平面狀態。 According to such an absorbent article, the rigidity of the upper end periphery of the absorbent core is improved by the reinforcing sheet in the entire lateral direction of the absorbent core. Therefore, the periphery of the upper end of the absorbent core is more difficult to bend and deform, and to maintain a flat state.

這樣的吸收性物品，其中，前述吸收性芯，是被芯包層薄片被覆，前述補強薄片被接合在前述芯包層薄片。 In such an absorbent article, the absorbent core is covered with a core-cladding sheet, and the reinforcing sheet is joined to the core-cladding sheet.

根據這樣的吸收性物品，經由芯包層薄片將補強薄片與吸收性芯一體化。因此，吸收性芯的上端周邊更加不易彎折不易變形，並容易維持平面狀態。 According to such an absorbent article, the reinforcing sheet and the absorbent core are integrated via the core-cladding sheet. Therefore, the periphery of the upper end of the absorbent core is more difficult to bend and deform, and to maintain a flat state.

這樣的吸收性物品，其中，前述補強薄片具有透氣性。 In such an absorbent article, the aforementioned reinforcing sheet has air permeability.

根據這樣的吸收性物品，所層積的薄片數雖增加，可是可抑制燜、熱的停滯，讓穿用感提升。 According to such an absorbent article, although the number of laminated sheets is increased, it is possible to suppress simmering and heat stagnation, and to improve the wearing feeling.

這樣的吸收性物品，其中，前述補強薄片被設在前述液透過性薄片與前述吸收性芯之間。 In such an absorbent article, the reinforcing sheet is provided between the liquid-permeable sheet and the absorbent core.

根據這樣的吸收性物品，隨著愈朝向縱向的上方側可慢慢降低吸收性本體的剛性，可抑制局處的剛性的變化。因此，吸收性芯的上端周邊更加不易彎折不易變形，穿用時的不舒適感也可減輕。 According to such an absorbent article, the rigidity of the absorbent body can be gradually reduced as it goes to the upper side in the longitudinal direction, and local changes in rigidity can be suppressed. Therefore, the periphery of the upper end of the absorbent core is more difficult to bend and deform, and the discomfort during wearing can be reduced.

這樣的吸收性物品，其中，前述吸收性芯被芯包層薄片被覆，前述芯包層薄片較前述吸收性芯的上端部朝前述縱向的上方側延伸出。 In such an absorbent article, the absorbent core is covered with a core-cladding sheet, and the core-cladding sheet extends toward the upper side of the longitudinal direction from the upper end of the absorbent core.

根據這樣的吸收性物品，藉由芯包層薄片可提高吸收性芯的上端周邊的剛性。尤其，在吸收性本體設有補強薄片時，在芯包層薄片與補強薄片的兩方可提高吸收性芯的上端周邊的剛性。因此，吸收性芯的上端周邊更加不易彎折不易變形，並容易維持平面狀態。又，可讓吸收性芯的上端周邊的剛性產生複數變化，可減輕穿用時的不舒適感。 According to such an absorbent article, the core-wrap sheet can increase the rigidity around the upper end of the absorbent core. In particular, when the absorbent main body is provided with a reinforcing sheet, the rigidity around the upper end of the absorbent core can be increased on both the core-cladding sheet and the reinforcing sheet. Therefore, the periphery of the upper end of the absorbent core is more difficult to bend and deform, and to maintain a flat state. In addition, the rigidity around the upper end of the absorbent core can be changed in multiple ways, and the discomfort during wearing can be reduced.

這樣的吸收性物品，其中，前述補強手段為不同的補強薄片。 In such an absorbent article, the aforementioned reinforcing means is a different reinforcing sheet.

In addition, the waist side of the wearer in the longitudinal direction is referred to as the upper side (upper), and the underside of the wearer's crotch is referred to as the lower side (lower). In addition, the ventral side of the wearer in the front-rear direction is referred to as the front side (front), and the back side of the wearer is referred to as the back side (rear).

紙尿褲1具有：沿著縱向的吸收性本體2及一對的腿褶邊部3、沿著橫向的一對的腰帶部4、一個腰圍開口部WH、以及一對的腿圍開口部LH。在褲型狀態的紙尿褲1(圖1)，吸收性本體2的長方向的一端部位在前方的上方，吸收性本體2的長方向的另一端部經由穿用者的***位在後方的上方。一對的腿褶邊部3沿著吸收性本體2的橫向兩側部位於此。 The diaper 1 has an absorbent body 2 along the longitudinal direction, a pair of leg hem portions 3, a pair of waistband portions 4 along the lateral direction, a waist opening WH, and a pair of leg openings LH. In the pants-shaped diaper 1 (FIG. 1 ), one end in the longitudinal direction of the absorbent main body 2 is located above the front, and the other end in the longitudinal direction of the absorbent main body 2 is located above the rear through the wearer's crotch. A pair of leg frills 3 are located here along the lateral sides of the absorbent body 2.

吸收性本體2是如圖2B所示，從其厚度方向的肌膚側(接觸穿用者之側)依序重疊液透過性薄片5(例如不織布等)、吸收體6、液不透過性薄片7(例如聚乙烯(PE)薄膜、聚丙烯(PP)薄膜等)、以及外裝薄片8(例如不織布等)。此外，和厚度方向鄰接的薄片5、7、8、吸收體6，是由不圖示的接著劑被接合。 As shown in FIG. 2B, the absorbent body 2 is formed by sequentially stacking a liquid-permeable sheet 5 (for example, non-woven fabric, etc.), an absorbent body 6, and a liquid-impermeable sheet 7 from the skin side (side contacting the wearer) in the thickness direction (For example, polyethylene (PE) film, polypropylene (PP) film, etc.), and the exterior sheet 8 (for example, non-woven fabric, etc.). In addition, the sheets 5, 7, 8, and the absorber 6 adjacent to the thickness direction are joined by an adhesive not shown.

吸收體6具備有：吸收性芯61、被覆吸收性芯61的外周面的芯包層薄片62。吸收性芯61，是將液體吸收性素材成形成預定的形狀者，在該實施形態，是將長 方向的兩端作成彎曲後的大致長方形狀。就液體吸收性素材來說，可例示紙漿纖維等的液體吸收性纖維、高吸收性聚合物(所謂SAP)等的液體吸收性粒狀物。就芯包層薄片62來說，可例示薄紙、不織布等的液透過性薄片。此外，吸收性芯61沒有被芯包層薄片62覆蓋亦可。 The absorber 6 includes an absorbent core 61 and a core-cladding sheet 62 covering the outer peripheral surface of the absorbent core 61. The absorbent core 61 is a liquid-absorbent material formed into a predetermined shape. In this embodiment, the long The two ends of the direction are bent into a roughly rectangular shape. As the liquid-absorbent material, liquid-absorbent fibers such as pulp fibers, and liquid-absorbent granular materials such as superabsorbent polymers (so-called SAP) can be exemplified. As the core-cladding sheet 62, liquid-permeable sheets such as tissue paper and non-woven fabric can be exemplified. In addition, the absorbent core 61 may not be covered by the core-cladding sheet 62.

在腿褶邊部3，是在橫向排列配置有可在縱向伸縮的複數個絲狀伸縮性構件3a(例如絲線橡膠等)。在腰帶部4，是在縱向排列配置有可在橫向伸縮的複數個絲狀伸縮性構件4a(例如絲線橡膠等)。又，沿著腿圍開口部LH設有伸縮性薄片10。因此，紙尿褲1貼合在穿用者的腰圍、腿圍。 In the leg hem portion 3, a plurality of thread-like stretchable members 3a (for example, thread rubber, etc.) that can stretch in the longitudinal direction are arranged in a horizontal direction. In the waistband portion 4, a plurality of thread-like stretchable members 4a (for example, thread rubber, etc.) that can stretch and contract in the lateral direction are arranged in a longitudinal direction. In addition, a stretchable sheet 10 is provided along the leg opening LH. Therefore, the diaper 1 fits the waist and leg circumferences of the wearer.

在紙尿褲1的前側，是利用一對的第1接合部51接合吸收性本體2的長方向的一端部中的橫向的側端、以及腿褶邊部3的上端、與一對的腰帶部4的各長方向的一端。在紙尿褲1的後側，是利用一對的第2接合部52接合吸收性本體2的長方向的另一端部中的橫向的側端、以及腿褶邊部3的上端、與一對的腰帶部4的各長方向的另一端。一對的第1接合部51，是從縱向的上方側(從腰圍開口部WH的橫方向中心)朝向一對的各腿圍開口部LH朝橫向外側傾斜。一對的第2接合部52也同樣地傾斜。 On the front side of the diaper 1, a pair of first joining parts 51 are used to join the lateral side end of the longitudinal end part of the absorbent body 2, the upper end of the leg hem part 3, and the pair of waistband parts 4 One end of each long direction. On the back side of the diaper 1, a pair of second joining parts 52 are used to join the lateral side end of the other end of the absorbent body 2 in the longitudinal direction, the upper end of the leg hem part 3, and a pair of waistbands. The other end in each longitudinal direction of the portion 4. The pair of first joining parts 51 are inclined laterally outward from the upper side in the longitudinal direction (from the center of the waist opening WH in the horizontal direction) toward the pair of leg openings LH. The pair of second joining parts 52 are also inclined in the same manner.

<紙尿褲1的製造方法> <Manufacturing method of diaper 1>

紙尿褲1在製造工程的最終階段成為圖2A所示的俯 視狀態。俯視狀態的紙尿褲1，是吸收性本體2與一對的腿褶邊部3及一對的腰帶部4的各長方向一致，使一對的腰帶部4重疊在吸收性本體2及一對的腿褶邊部3的肌膚側面，並且將一對的腿褶邊部3及一對的腰帶部4朝長方向伸長。在俯視狀態的紙尿褲1，將一對的腰帶部4的各橫向的內側端4b朝橫向外側打開，邊將一對的腰帶部4分別在其長方向的中央部對折，邊將吸收性本體2及一對的腿褶邊部3在各自的長方向的中央部對折，而形成褲型狀態的紙尿褲1(圖1)。 In the final stage of the manufacturing process, the diaper 1 becomes the top view shown in Figure 2A. Depending on the state. The diaper 1 in a plan view has the absorbent body 2 and a pair of leg ruffles 3 and a pair of waistbands 4 in the same longitudinal direction, so that the pair of waistbands 4 overlap the absorbent body 2 and a pair of On the skin side of the leg frill part 3, a pair of leg frill parts 3 and a pair of waistband parts 4 are extended in the longitudinal direction. In the diaper 1 in a plan view, the lateral inner ends 4b of the pair of waistband portions 4 are opened to the laterally outer side, and the pair of waistband portions 4 are respectively folded in half at the center of the longitudinal direction, and the absorbent body 2 is folded. And a pair of leg hemming parts 3 are folded in half at the center part of each longitudinal direction, and the diaper 1 (FIG. 1) of a pants-shaped state is formed.

腿褶邊部3及腰帶部4，是由相同的薄片構件9所形成。如圖3B所示在薄片構件9，是在厚度方向重疊不織布等的二片的薄片91、91，將腿褶邊部3用的絲狀伸縮性構件3a與腰帶部4用的絲狀伸縮性構件4a及伸縮性薄片10，以朝長方向被伸長的狀態下被固定在這之間。一對的薄片構件9，是沿著吸收性本體2的橫向兩側部被設置，薄片構件9的橫向內側的端部被接合在液透過性薄片5與液不透過性薄片7之間。而且，在薄片構件9中伸縮性薄片10存在的部位挖空腿圍開口部LH用的孔。因此，形成伸縮性薄片10沿著腿圍開口部LH存在於全周。又，因為薄片構件9的橫向外側的端部，是朝橫向內側折疊2次，所以，能減輕穿用時施加在腰圍部分的壓力。 The leg hem portion 3 and the waistband portion 4 are formed of the same sheet member 9. As shown in Fig. 3B, in the sheet member 9, two sheets 91, 91 such as non-woven fabrics are stacked in the thickness direction, and the thread-like stretchable member 3a for the leg hem part 3 and the waistband part 4 The member 4a and the stretchable sheet 10 are fixed between them in a state extended in the longitudinal direction. A pair of sheet members 9 are provided along both lateral sides of the absorptive main body 2, and the lateral inner ends of the sheet members 9 are joined between the liquid-permeable sheet 5 and the liquid-impermeable sheet 7. In addition, a hole for the leg opening LH is hollowed out in the sheet member 9 where the stretchable sheet 10 exists. Therefore, the stretchable sheet 10 is formed over the entire circumference along the leg opening LH. In addition, since the laterally outer end of the sheet member 9 is folded toward the laterally inner side twice, the pressure applied to the waist portion during wearing can be reduced.

薄片構件9在朝長方向延伸的折疊線FL朝吸收性本體2的肌膚側面側被折疊。與吸收性本體2在橫向 排列的薄片構件9的部位成為腿褶邊部3，與吸收性本體2及腿褶邊部3在厚度方向重疊的薄片構件9的部位成為腰帶部4。而且，由一對的第1接合部51及一對的第2接合部52接合吸收性本體2及腿褶邊部3、與腰帶部4。之後，藉由切斷去除較一對的第1接合部51及一對的第2接合部52更位於長方向外側的部位，製造圖2A所示的俯視狀態的紙尿褲1。此外，就由第1接合部51及第2接合部52的接合方法來說，是例如，可例示接著劑、熱密封、超音波密封、該等的組合等公知的接合方法。 The sheet member 9 is folded toward the skin side of the absorbent main body 2 along a folding line FL extending in the longitudinal direction. With absorptive body 2 in horizontal The part of the sheet members 9 arranged in line becomes the leg hem part 3, and the part of the sheet member 9 overlapping the absorbent main body 2 and the leg hem part 3 in the thickness direction becomes the waistband part 4. Furthermore, the absorptive main body 2 and the leg gathers 3 and the waistband 4 are joined by a pair of first joining parts 51 and a pair of second joining parts 52. After that, by cutting and removing the part located on the outer side in the longitudinal direction from the pair of the first joining part 51 and the pair of the second joining part 52, the diaper 1 in the plan state shown in FIG. 2A is manufactured. In addition, as for the joining method of the first joining part 51 and the second joining part 52, for example, known joining methods such as adhesives, heat sealing, ultrasonic sealing, and combinations of these can be exemplified.

<補強手段20及補強薄片30> <Reinforcement means 20 and reinforcement sheet 30>

如圖3A所示，作為構成吸收性本體2的薄片的液透過性薄片5、液不透過性薄片7、以及外裝薄片8的長方向的長度，是比吸收性芯61的長方向的長度更長，比吸收性芯61的長方向的兩端更來到長方向的兩外側。換言之，在褲型狀態的紙尿褲(圖1)的前側及後側，構成吸收性本體2的薄片5、7、8，是超過吸收性芯61來到縱向的上方側。因此，在吸收性本體2形成從縱向上方排列在薄片間僅吸收性芯61不存在的薄片的區域、以及在薄片間吸收性芯61存在的區域的狀況。 As shown in FIG. 3A, the length in the longitudinal direction of the liquid-permeable sheet 5, the liquid-impermeable sheet 7, and the outer cover sheet 8 as the sheets constituting the absorbent body 2 is greater than the length in the longitudinal direction of the absorbent core 61 It is longer and comes to both outer sides of the longitudinal direction than the both ends of the absorbent core 61 in the longitudinal direction. In other words, on the front and back sides of the pants-shaped diaper (FIG. 1 ), the sheets 5, 7, and 8 constituting the absorbent main body 2 extend beyond the absorbent core 61 to the upper side in the longitudinal direction. Therefore, in the absorptive main body 2, the area of the sheet where only the absorbent core 61 does not exist between the sheets and the area where the absorbent core 61 exists between the sheets are arranged in the absorbent main body 2 from above in the longitudinal direction.

前述區域的邊界周邊，亦即，在吸收性芯61的上端61a周邊，若吸收性芯61柔軟則其本身容易變形，或因僅薄片的區域與吸收性芯61存在的區域的厚度不同等，使薄片容易彎折或變形。此時，在吸收性芯61 的上端61a周邊產生皺紋，或吸收性芯61的輪廓浮起。這麼一來，會有***物從因皺紋產生的間隙漏出，或紙尿褲1的外觀降低的情況。又，紙尿褲1，是藉由第1接合部51及第2接合部52將腰帶部4的長方向的末端接合在吸收性本體2的橫向的側端，而使腰帶部4的絲狀伸縮性構件4a不會橫切吸收性本體2。亦即，因為吸收性本體2為非伸縮性的構件，所以，在吸收性芯61的上端61a周邊與穿用者的身體之間容易產生間隙。 The periphery of the boundary of the aforementioned area, that is, around the upper end 61a of the absorbent core 61, if the absorbent core 61 is soft, the absorbent core itself is easily deformed, or only the sheet area and the area where the absorbent core 61 exists have different thicknesses. Make the sheet easy to bend or deform. At this time, in the absorbent core 61 Wrinkles are generated around the upper end 61a of the tube, or the contour of the absorbent core 61 rises. In this way, excrement may leak from the gaps due to wrinkles, or the appearance of the diaper 1 may decrease. In addition, the diaper 1 connects the longitudinal ends of the waistband 4 to the lateral side ends of the absorbent body 2 by the first joining part 51 and the second joining part 52, thereby making the waistband 4 more flexible The member 4a does not cross the absorbent body 2. That is, because the absorbent body 2 is a non-stretchable member, a gap is likely to be generated between the periphery of the upper end 61a of the absorbent core 61 and the body of the wearer.

於此，紙尿褲1，是在褲型狀態中的前後方向的兩方(腹側及背側)，在吸收性芯61的上端部設有提高其吸收性芯61的上端部剛性的補強手段20(圖3A的格網部)。亦即，在吸收性芯61的長方向兩端部設有補強手段20。補強手段20，是指在吸收性芯61設置朝厚度方向壓縮吸收性芯61提高該吸收性芯61的平均密度的部位。因此，設有補強手段20的區域(以下補強區域21)中的吸收性芯61的平均密度較鄰接補強區域21的區域中的吸收性芯61的平均密度變的更高。 Here, the diaper 1 is in both the front and rear directions (ventral side and back side) in the pants-shaped state, and the upper end of the absorbent core 61 is provided with reinforcing means 20 for increasing the rigidity of the upper end of the absorbent core 61. (The grid part of Figure 3A). That is, the reinforcing means 20 are provided at both ends in the longitudinal direction of the absorbent core 61. The reinforcing means 20 means that the absorbent core 61 is provided at a location where the absorbent core 61 is compressed in the thickness direction to increase the average density of the absorbent core 61. Therefore, the average density of the absorbent core 61 in the region where the reinforcing means 20 is provided (hereinafter the reinforcing region 21) is higher than the average density of the absorbent core 61 in the region adjacent to the reinforcing region 21.

具體而言，可舉分散設置壓縮吸收性芯61使吸收性芯61的密度(g/m3)提高的複數個凹部的方法，亦即，可舉在吸收性芯61的上端部施予壓花圖案，部分壓縮吸收性芯61的上端部的方法。其他，也可在吸收性芯61的上端部施予沖壓加工，壓縮吸收性芯61的上端部全域。此外，補強區域21中的被壓縮的部位的厚度，是例如可設在鄰接補強區域21的區域的厚度的一半以下。 又，鄰接補強區域21的區域，是可例示較補強區域21更下方(長方向的中央側)的吸收性芯61的區域，即與補強區域21相同大小及相同形狀的區域，可是，不限於此，也可與補強區域21不同大小、不同形狀的區域。就吸收性芯61的平均密度的比較方法來說，是可例示分別切出補強區域21及鄰接補強區域21的區域測量質量，其質量除以區域的面積算出基量(g/cm2)，其基量除以區域的厚度算出平均密度(g/cm3)進行比較的方法；藉由電子顯微鏡等對朝厚度方向切補強區域21等的剖面進行攝影，以目視比較構成吸收性芯61的液體吸收性素材的密度、或以液體吸收性素材的數量進行比較的方法。可是不限於此，只要可在補強區域21與鄰接補強區域21的區域比較吸收性芯61的平均密度的方法，則任何的方法亦可。 Specifically, a method of distributing a plurality of recesses to increase the density (g/m 3 ) of the absorbent core 61 by compressing the absorbent core 61 can be cited, that is, applying pressure to the upper end of the absorbent core 61 Flower pattern, a method of partially compressing the upper end of the absorbent core 61. In addition, press processing may be applied to the upper end of the absorbent core 61 to compress the entire upper end of the absorbent core 61. In addition, the thickness of the compressed portion in the reinforced region 21 can be set to be less than half of the thickness of the region adjacent to the reinforced region 21, for example. In addition, the area adjacent to the reinforced area 21 is an area that can exemplify the absorbent core 61 below the reinforced area 21 (the center side in the longitudinal direction), that is, an area of the same size and shape as the reinforced area 21, but is not limited to Therefore, it may be a region of a different size and shape from the reinforcement region 21. As for the method of comparing the average density of the absorbent core 61, it is exemplified to cut out the reinforced area 21 and the area adjacent to the reinforced area 21 to measure the mass, divide the mass by the area of the area to calculate the basis weight (g/cm 2 ), The base amount is divided by the thickness of the area to calculate the average density (g/cm 3 ) for comparison; the cross section of the reinforced area 21 etc. cut in the thickness direction is photographed with an electron microscope or the like, and the components constituting the absorbent core 61 are visually compared A method of comparing the density of liquid-absorbing materials or the number of liquid-absorbing materials. However, it is not limited to this, and any method may be used as long as the average density of the absorbent core 61 can be compared between the reinforced region 21 and the region adjacent to the reinforced region 21.

如此，在吸收性芯61的上端部設置補強手段20，使吸收性芯61的上端部的剛性提高，使吸收性芯61的上端部成為不易彎折不易變形。又，吸收性芯61的上端部維持平面狀態，較吸收性芯61更上方的僅由薄片形成的柔軟的區域也受到吸收性芯61的上端部的影響而維持平面狀態。亦即，在吸收性芯61的上端61a周邊維持吸收性本體2的平面狀態。因此，在吸收性本體2與穿用者的身體之間不易產生間隙，使紙尿褲1的貼合性提升。又，抑制在吸收性芯61的上端周邊的皺紋的發生、吸收性芯61的輪廓的浮起，可抑制來自皺紋的***物的漏 出、紙尿褲1的外觀的降低。此外，就吸收性芯61的剛性值來說，例如可例示藉由格利剛軟度所測量的值除以樣本片的長度的值。格利剛軟度的測量，是可使用(株)安田精機製作所製的No311的格利式柔軟度試驗機，以JIS-L1096為依據進行測量。 In this way, the reinforcing means 20 is provided on the upper end of the absorbent core 61 to increase the rigidity of the upper end of the absorbent core 61 and make the upper end of the absorbent core 61 hard to bend and deform. In addition, the upper end of the absorbent core 61 maintains a flat state, and the soft region formed only by the sheet above the absorbent core 61 is also affected by the upper end of the absorbent core 61 to maintain the flat state. That is, the planar state of the absorbent main body 2 is maintained around the upper end 61a of the absorbent core 61. Therefore, a gap is not easily generated between the absorbent body 2 and the wearer's body, and the fit of the diaper 1 is improved. In addition, the occurrence of wrinkles around the upper end of the absorbent core 61 and the floating of the contour of the absorbent core 61 are suppressed, and the leakage of excrement from wrinkles can be suppressed. Out, the appearance of the diaper 1 is reduced. In addition, as for the rigidity value of the absorbent core 61, for example, the value measured by the Gurley stiffness divided by the length of the sample piece can be exemplified. The Gurley stiffness and softness can be measured by using the No311 Gurley-type softness tester manufactured by Yasuda Seiki Seisakusho Co., Ltd. based on JIS-L1096.

尤其，紙尿褲1，是藉由從腰圍開口部WH朝向腿圍開口部LH朝橫向外側傾斜的第1接合部51及第2接合部52接合吸收性本體2與腰帶部4，而使紙尿褲1接近內褲的形狀。因此，抑制吸收性芯61的輪廓的浮起，使得像似紙尿褲的印象更薄，可減輕對穿用紙尿褲的抵抗感。又，在紙尿褲1，腰帶部4的絲狀伸縮性構件4a不會橫切吸收性本體2。因此，在吸收性本體2不會產生因伸縮性構件的收縮造成的縱皺紋。另一方面，即使在吸收性本體2不配置伸縮性構件，在紙尿褲1是如上述，在吸收性芯61的上端周邊可維持吸收性本體2的平面狀態，也可獲得貼合性。 In particular, in the diaper 1, the first joining portion 51 and the second joining portion 52 that are inclined laterally outward from the waist opening WH toward the leg opening LH join the absorbent body 2 and the waistband 4, so that the diaper 1 approaches The shape of the panties. Therefore, the floating of the contour of the absorbent core 61 is suppressed, the impression of a diaper is made thinner, and the resistance to wearing the diaper can be reduced. In addition, in the diaper 1, the filamentous elastic member 4a of the waistband 4 does not cross the absorbent main body 2. Therefore, the absorptive main body 2 does not generate longitudinal wrinkles due to the contraction of the stretchable member. On the other hand, even if a stretchable member is not arranged in the absorbent main body 2, as in the diaper 1 as described above, the flat state of the absorbent main body 2 can be maintained around the upper end of the absorbent core 61, and fitability can be obtained.

又，壓花加工、沖壓加工等壓縮吸收性芯61的上端部的至少一部分提高吸收性芯61的剛性時，吸收性芯61的上端部的厚度變薄，且與較吸收性芯61更上方的僅由薄片形成的區域的厚度的差變小。因此，吸收性芯61的上端61a周邊更加不易彎折不易變形，能抑制皺紋的發生等。又，壓花加工、沖壓加工的條件例如依據壓縮後的吸收性芯61的厚度、壓縮的部位的大小、形狀、數量、配置等可自由設定吸收性芯61的上端部的剛性值。 Moreover, when at least a part of the upper end portion of the absorbent core 61 is compressed by embossing or press processing to increase the rigidity of the absorbent core 61, the thickness of the upper end portion of the absorbent core 61 becomes thinner and higher than the absorbent core 61 The difference in the thickness of the region formed only by the flakes becomes smaller. Therefore, the periphery of the upper end 61a of the absorbent core 61 is more difficult to bend and deform, and the occurrence of wrinkles and the like can be suppressed. In addition, the conditions of embossing and press processing can freely set the rigidity value of the upper end of the absorbent core 61 according to the thickness of the compressed absorbent core 61, the size, shape, number, and arrangement of the compressed portion, for example.

再者，紙尿褲1，是在褲型狀態中的前後方向的兩方(腹側及背側)，設有跨吸收性芯61的上端61a的補強薄片30。亦即，在吸收性芯61的長方向兩端61a周邊分別設有補強薄片30。又，補強薄片30與補強區域21的一部分在厚度方向重疊。因此，在吸收性芯61的上端61a周邊吸收性本體2的剛性進一步提高。因此，更確實維持吸收性本體2的平面狀態，可抑制來自皺紋的***物的漏出等。尤其，可抑制較吸收性芯61更上方的僅由薄片形成的區域中的皺紋的產生。又，因為補強薄片30跨吸收性芯61的上端61a，所以，僅由薄片形成的區域與吸收性芯61存在的區域的邊界不易彎折，吸收性芯61的輪廓不易浮起。 In addition, the diaper 1 is provided with reinforcing sheets 30 spanning the upper end 61a of the absorbent core 61 on both sides (ventral side and back side) in the front-rear direction in the pants-shaped state. That is, the reinforcing sheet 30 is respectively provided around both ends 61 a in the longitudinal direction of the absorbent core 61. In addition, the reinforcing sheet 30 overlaps a part of the reinforcing region 21 in the thickness direction. Therefore, the rigidity of the absorbent main body 2 around the upper end 61a of the absorbent core 61 is further improved. Therefore, the flat state of the absorptive main body 2 is more reliably maintained, and the leakage of excrement from wrinkles and the like can be suppressed. In particular, it is possible to suppress the generation of wrinkles in the region formed only of the sheet above the absorbent core 61. In addition, since the reinforcing sheet 30 straddles the upper end 61a of the absorbent core 61, the boundary between the area formed only by the sheet and the area where the absorbent core 61 exists is not easily bent, and the outline of the absorbent core 61 is not easily raised.

補強薄片30，是如圖2B所示，被設在液透過性薄片5與吸收性芯61之間。此時，例如即使構成吸收性芯61的粒狀的高吸收性聚合物從芯包層薄片62的長方向的末端漏出，也可用補強薄片30壓住，可抑制高吸收性聚合物跑出到液透過性薄片5的表面的情況。又，為了提高剛性可用補強薄片30覆蓋被壓縮變硬的吸收性芯61的上端部，可減輕穿用時的不舒適感。 The reinforcing sheet 30 is provided between the liquid-permeable sheet 5 and the absorbent core 61 as shown in FIG. 2B. At this time, for example, even if the particulate superabsorbent polymer constituting the absorbent core 61 leaks from the end of the core clad sheet 62 in the longitudinal direction, it can be suppressed by the reinforcing sheet 30 to prevent the superabsorbent polymer from escaping to The surface of the liquid-permeable sheet 5. In addition, in order to increase rigidity, the upper end portion of the absorbent core 61 that has been compressed and hardened can be covered with the reinforcing sheet 30, so that the discomfort during wearing can be reduced.

又，在褲型狀態的紙尿褲1，補強薄片30的縱向的長度比吸收性芯61的縱向的長度(即從製品長邊中央到吸收性芯61的上端61a的長度)更短。因此，補強薄片30只有與吸收性芯61的長方向的兩端部在厚度方向重疊，與兩端部以外的部位沒有重疊。如此，不要將補 強薄片30作成的太長為理想。這樣一來，可實現低成本化。又，可防止較吸收性芯61更位於肌膚側的補強薄片30阻礙吸收性芯61的液體吸收的情況。 In addition, in the pants-shaped diaper 1, the longitudinal length of the reinforcing sheet 30 is shorter than the longitudinal length of the absorbent core 61 (that is, the length from the center of the long side of the product to the upper end 61a of the absorbent core 61). Therefore, the reinforcing sheet 30 only overlaps the both ends in the longitudinal direction of the absorbent core 61 in the thickness direction, and does not overlap with parts other than the both ends. So, don’t make up It is ideal that the strong sheet 30 is made too long. In this way, cost reduction can be achieved. In addition, it is possible to prevent the reinforcing sheet 30 on the skin side than the absorbent core 61 from hindering the absorption of liquid by the absorbent core 61.

又，補強薄片30具有透氣性為理想。這樣一來，即使為了提高吸收性芯61的上端61a周邊的剛性而增加薄片的層積數，也能抑制燜、熱的停滯，使穿用感提升。又，補強薄片30具有透液過性為理想。這樣一來，可防止較吸收性芯61更位於肌膚側的補強薄片30阻礙吸收性芯61的液體吸收的情況。具體而言，雖可例示基重為30g/cm2左右的紡黏不織布、SMS不織布等作為補強薄片30，可是不限於此。 In addition, it is desirable that the reinforcing sheet 30 has air permeability. In this way, even if the number of layers of the sheet is increased in order to increase the rigidity around the upper end 61a of the absorbent core 61, the stagnation of simmering and heat can be suppressed and the wearing feeling can be improved. In addition, it is desirable that the reinforcing sheet 30 has liquid permeability. In this way, it is possible to prevent the reinforcing sheet 30 on the skin side than the absorbent core 61 from hindering the absorption of liquid by the absorbent core 61. Specifically, although spunbonded nonwoven fabric, SMS nonwoven fabric, etc., having a basis weight of about 30 g/cm 2 can be exemplified as the reinforcing sheet 30, it is not limited to this.

又，補強薄片30，是用熱熔接著劑等的接著劑31被接合在芯包層薄片62。這樣一來，補強薄片30經由芯包層薄片62與吸收性芯61一體化，在吸收性芯61的上端61a周邊吸收性本體2的剛性進一步提高。因此，更確實維持吸收性本體2的平面狀態，可抑制來自皺紋的***物的漏出等。此外，就接著劑31的塗佈圖案來說，可舉螺旋圖案、條狀圖案。又，不限於用接著劑接合補強薄片30與芯包層薄片62，例如也可用熱密封、超音波密封等接合。可是不限於此，沒有接合補強薄片30與芯包層薄片62亦可。又，吸收性芯61沒有被芯包層薄片62被覆時，將補強薄片30直接接合在吸收性芯61即可。 In addition, the reinforcing sheet 30 is bonded to the core cladding sheet 62 with an adhesive 31 such as a hot melt adhesive. In this way, the reinforcing sheet 30 is integrated with the absorbent core 61 via the core-cladding sheet 62, and the rigidity of the absorbent main body 2 around the upper end 61a of the absorbent core 61 is further improved. Therefore, the flat state of the absorptive main body 2 is more reliably maintained, and the leakage of excrement from wrinkles and the like can be suppressed. In addition, examples of the coating pattern of the adhesive 31 include a spiral pattern and a striped pattern. In addition, it is not limited to joining the reinforcing sheet 30 and the core cladding sheet 62 with an adhesive, and may be joined by heat sealing, ultrasonic sealing, or the like, for example. However, it is not limited to this, and the reinforcing sheet 30 and the core cladding sheet 62 may not be joined. In addition, when the absorbent core 61 is not covered by the core-cladding sheet 62, the reinforcing sheet 30 may be directly joined to the absorbent core 61.

此外，如圖3A所示，在紙尿褲1製造途中， 補強薄片30是長方形狀的薄片，其薄片的一邊對齊吸收性本體2的長方向的末端被配置。而且，補強薄片30，是藉由一對的第1接合部51或一對的第2接合部52接合吸收性本體2與腰帶部4。之後，將較第1接合部51及第2接合部52更朝縱向外側延伸出的補強薄片30的部位與其他的薄片一起切斷，補強薄片30成為六角形。 In addition, as shown in FIG. 3A, during the manufacture of the diaper 1, The reinforcing sheet 30 is a rectangular sheet, and one side of the sheet is arranged to be aligned with the longitudinal end of the absorbent body 2. In addition, the reinforcing sheet 30 joins the absorptive main body 2 and the waistband 4 by a pair of first joining parts 51 or a pair of second joining parts 52. After that, the part of the reinforcing sheet 30 that extends further in the longitudinal direction than the first joining portion 51 and the second joining portion 52 is cut together with other sheets, and the reinforcing sheet 30 becomes a hexagon.

又，在褲型狀態的紙尿褲1，補強薄片30的下端30a位在一對的第1接合部51的下端51a或較一對的第2接合部52的下端52a更位在縱向的上方側。此時，如圖3A的製造途中的紙尿褲1所示，補強薄片30的下端30a成為較腿圍開口部LH更位於上方(長方向的外側)。因此，可防止補強薄片30阻礙穿用者的腿的動作，可減輕穿用時的不舒適感。如此，不要將補強薄片30作的太長，實現低成本化，又，可防止較吸收性芯61更位於肌膚側的補強薄片30阻礙吸收性芯61的液體吸收的情況。此外，補強薄片30的下端30a與第1接合部51的下端51a或第2接合部52的下端52a一致亦可，此時也可獲得上述的效果。又，不限於上述，補強薄片30的下端30a也可較第1接合部51的下端51a、第2接合部52的下端52a更位在縱向的下方側。 In the diaper 1 in the pant-shaped state, the lower end 30a of the reinforcing sheet 30 is located at the lower end 51a of the pair of first joining parts 51 or is located on the upper side in the longitudinal direction than the lower end 52a of the pair of second joining parts 52. At this time, as shown in the diaper 1 in the middle of manufacturing of FIG. 3A, the lower end 30a of the reinforcing sheet 30 is positioned above the leg opening LH (outside in the longitudinal direction). Therefore, the reinforcing sheet 30 can be prevented from hindering the movement of the wearer's legs, and the discomfort during wearing can be reduced. In this way, it is not necessary to make the reinforcing sheet 30 too long to realize cost reduction, and to prevent the reinforcing sheet 30 on the skin side than the absorbent core 61 from hindering the absorption of liquid by the absorbent core 61. In addition, the lower end 30a of the reinforcing sheet 30 may coincide with the lower end 51a of the first joining portion 51 or the lower end 52a of the second joining portion 52, and the above-mentioned effects can also be obtained in this case. In addition, not limited to the above, the lower end 30a of the reinforcing sheet 30 may be positioned on the lower side in the longitudinal direction than the lower end 51a of the first joint 51 and the lower end 52a of the second joint 52.

又，補強區域21的下端21a，是縱向的上方側成凸地彎曲。因此，在吸收性芯61的橫向中的端部區域，是補強薄片30的下端30a與補強區域21的下端21a的縱向位置幾乎相同，而相對於此，在吸收性芯61的橫 向中的中央區域，是補強薄片30的下端30a較補強區域21的下端21a更位於下方。因此，為了提高剛性可用補強薄片30覆蓋被壓縮變硬的吸收性芯61的上端部的大部分，可減輕穿用時的不舒適感。可是不限於此，在吸收性芯61的橫向的全域，補強薄片30的下端30a也可較補強區域21的下端21a更位於下方。 In addition, the lower end 21a of the reinforced region 21 is convexly curved on the upper side in the longitudinal direction. Therefore, in the end region in the transverse direction of the absorbent core 61, the longitudinal positions of the lower end 30a of the reinforcing sheet 30 and the lower end 21a of the reinforcing region 21 are almost the same, and in contrast to this, in the transverse direction of the absorbent core 61 In the central area in the middle, the lower end 30a of the reinforcing sheet 30 is located below the lower end 21a of the reinforcing area 21. Therefore, in order to increase the rigidity, most of the upper end of the absorbent core 61 that has been compressed and hardened can be covered with the reinforcing sheet 30, so that the discomfort during wearing can be reduced. However, it is not limited to this, and the lower end 30a of the reinforcing sheet 30 may be located below the lower end 21a of the reinforcing region 21 in the entire horizontal direction of the absorbent core 61.

圖4，是吸收性本體2中的橫向的中央區域的剖視圖。如圖示，在吸收性本體2中的橫向的中央區域，是從其上端朝向下方側排列：構成吸收性本體2的薄片5、7、8與補強薄片30重疊的區域A1；構成吸收性本體2的薄片5、7、8與補強薄片30和吸收性芯61的補強區域21重疊的區域A2；構成吸收性本體2的薄片5、7、8與補強薄片30和補強區域21外的吸收性芯61重疊的區域A3；以及重疊構成吸收性本體2的薄片5、7、8與補強區域21外的吸收性芯61的區域A4。在該等的區域A1~A4，吸收性本體2的剛性不同。亦即，在縱向錯開補強薄片30的下端30a與補強區域21的下端21a，在吸收性芯61的上端61a周邊，可讓吸收性本體2的剛性在縱向產生複數變化。因此，可減輕穿用時的不舒適感。 FIG. 4 is a cross-sectional view of the central area in the horizontal direction in the absorbent body 2. As shown in the figure, the horizontal central area in the absorbent body 2 is arranged from its upper end toward the lower side: the area A1 where the sheets 5, 7, 8 constituting the absorbent body 2 and the reinforcing sheet 30 overlap; constituting the absorbent body 2 The area A2 where the sheets 5, 7, 8 overlap the reinforcing sheet 30 and the reinforcing area 21 of the absorbent core 61; the sheets 5, 7, 8 and the reinforcing sheet 30 and the reinforcing area 21 constituting the absorbent body 2 are absorptive The area A3 where the core 61 overlaps; and the area A4 where the sheets 5, 7, 8 constituting the absorbent body 2 and the absorbent core 61 outside the reinforcing area 21 overlap. In these areas A1 to A4, the rigidity of the absorbent main body 2 is different. That is, the lower end 30a of the reinforcing sheet 30 and the lower end 21a of the reinforcing region 21 are staggered in the longitudinal direction, and around the upper end 61a of the absorbent core 61, the rigidity of the absorbent body 2 can be changed in the longitudinal direction. Therefore, discomfort during wearing can be reduced.

又，紙尿褲1，是被覆吸收性芯61的芯包層薄片62比吸收性芯61的上端部朝縱向的上方側延伸出。此時，除了上述的區域A1~A4之外，有構成吸收性本體2的薄片5、7、8與補強薄片30和芯包層薄片62重疊的區域A5存在。亦即，因為有吸收性本體2的剛性與上述 的區域A1~A4不同的區域A5存在，所以，可讓吸收性本體2的剛性較縱向更多階段變化，可更進一步減輕穿用時的不舒適感。 In addition, in the diaper 1, the core-cladding sheet 62 covering the absorbent core 61 extends toward the upper side in the longitudinal direction from the upper end portion of the absorbent core 61. At this time, in addition to the aforementioned areas A1 to A4, there is an area A5 where the sheets 5, 7, and 8 constituting the absorbent body 2 overlap with the reinforcing sheet 30 and the core-cladding sheet 62. That is, because of the rigidity of the absorbent body 2 and the above There are different areas A1 to A4 in the area A5, so the rigidity of the absorbent body 2 can be changed in more stages than the longitudinal direction, which can further reduce the discomfort when wearing.

又，從吸收性芯61的上端61a延伸出的芯包層薄片62發揮與補強薄片30同樣的功用。因此，在吸收性芯61的上端61a周邊，吸收性本體2的剛性進一步提高，維持吸收性本體2的俯視狀態，可抑制來自皺紋的***物的漏出等。尤其，在紙尿褲1設有補強薄片30時，在芯包層薄片62與補強薄片30的兩方可提高吸收性芯61的上端61a周邊的剛性。可是不限於此，例如吸收性芯61的上端61a與芯包層薄片62的上端一致亦可。 In addition, the core-cladding sheet 62 extending from the upper end 61 a of the absorbent core 61 performs the same function as the reinforcing sheet 30. Therefore, in the vicinity of the upper end 61a of the absorbent core 61, the rigidity of the absorbent body 2 is further improved, the plan view state of the absorbent body 2 is maintained, and the leakage of excrement from wrinkles and the like can be suppressed. In particular, when the diaper 1 is provided with the reinforcing sheet 30, the rigidity around the upper end 61a of the absorbent core 61 can be increased in both the core-cladding sheet 62 and the reinforcing sheet 30. However, it is not limited to this. For example, the upper end 61a of the absorbent core 61 may coincide with the upper end of the core-cladding sheet 62.

又，補強區域21的下端，亦即，吸收性芯61的上端61a，是縱向的上方側成凸地彎曲。因此，補強區域21的橫向長度，是隨著朝向縱向的上方側變短，並隨著朝向縱向的上方側慢慢降低吸收性本體2的剛性，可抑制局處的剛性的變化。因此，吸收性芯61的上端周邊更加不易彎折不易變形，且穿用時的不舒適感也可減輕。可是不限於此，例如補強區域21的橫向的長度不限縱向的位置也可一定。 In addition, the lower end of the reinforcing region 21, that is, the upper end 61a of the absorbent core 61, is convexly curved on the upper side in the longitudinal direction. Therefore, the lateral length of the reinforcing region 21 becomes shorter toward the upper side in the longitudinal direction, and gradually decreases the rigidity of the absorbent body 2 toward the upper side in the longitudinal direction, so that local changes in rigidity can be suppressed. Therefore, the periphery of the upper end of the absorbent core 61 is more difficult to bend and deform, and the discomfort during wearing can be reduced. However, it is not limited to this. For example, the lateral length of the reinforcing region 21 may be constant regardless of the longitudinal position.

===第2實施形態=== ===Second Embodiment ===

圖5，是第2實施形態的紙尿褲1的剖視圖。在第2實施形態的紙尿褲1沒有設置補強薄片30。此時，也只要在紙尿褲1設置提高吸收性芯61的上端部的剛性的補 強手段20，則提高吸收性芯61的上端周邊中的吸收性本體2的剛性，可維持吸收性本體2的平面狀態，可抑制來自皺紋的***物的漏出等。 Fig. 5 is a cross-sectional view of the diaper 1 according to the second embodiment. In the diaper 1 of the second embodiment, the reinforcing sheet 30 is not provided. At this time, it is only necessary to provide a supplement to increase the rigidity of the upper end of the absorbent core 61 in the diaper 1. The strong means 20 increases the rigidity of the absorptive main body 2 in the periphery of the upper end of the absorptive core 61, can maintain the flat state of the absorptive main body 2, and can suppress the leakage of excrement from wrinkles.

===第3實施形態=== ===The third embodiment ===

圖6，是第3實施形態的紙尿褲1的製造途中的俯視圖。第3實施形態的紙尿褲1，是補強薄片30的橫向的末端30b較吸收性芯61的橫向的末端61b更位橫向的外側。因此，在吸收性芯61的橫向全域可提高吸收性芯61的上端周邊中的吸收性本體2的剛性。又，構成吸收性本體2的薄片5、7、8，較吸收性芯61的橫向的末端61b更來到橫向外側時，在橫向也排列只有薄片的區域與在薄片間吸收性芯61存在的區域。因此，如上述，將補強薄片30的橫向長度增長，使橫向中的前述區域的邊界周邊不易彎折不易變形。因此，吸收性芯61的輪廓更不易浮出。此外，補強薄片30的橫向的末端與吸收性芯61的橫向的末端一致亦可，此時也可獲得上述的效果。 Fig. 6 is a plan view in the process of manufacturing the diaper 1 of the third embodiment. In the diaper 1 of the third embodiment, the lateral end 30b of the reinforcing sheet 30 is positioned on the lateral outer side than the lateral end 61b of the absorbent core 61. Therefore, the rigidity of the absorbent body 2 in the upper end periphery of the absorbent core 61 can be increased in the entire lateral direction of the absorbent core 61. Furthermore, when the sheets 5, 7, and 8 constituting the absorbent main body 2 are positioned further to the outside in the lateral direction than the lateral end 61b of the absorbent core 61, the area where only the sheets and the absorbent core 61 exist between the sheets are also arranged in the lateral direction. area. Therefore, as described above, the lateral length of the reinforcing sheet 30 is increased, so that the periphery of the boundary of the aforementioned region in the lateral direction is not easily bent and deformed. Therefore, the outline of the absorbent core 61 is less likely to rise. In addition, the lateral end of the reinforcing sheet 30 may coincide with the lateral end of the absorbent core 61, and the above-mentioned effects can also be obtained in this case.

===第4實施形態=== === Fourth Embodiment ===

圖7A，是第4實施形態的紙尿褲1的一部分的俯視圖，圖7B，是第4實施形態的紙尿褲1的剖視圖。第4實施形態的紙尿布1，是如圖7A所示，補強區域21的下端21a不彎曲地沿著橫向。而且，補強區域21的下端21a在橫向全域較補強薄片30的下端30a更位在縱向的下方 側。此時也與第1實施形態同樣，如圖7B所示，在吸收性芯61的上端周邊因為可設置吸收性本體2的剛性不同的複數個區域A1’~A4’，所以可減輕穿用時的不舒適感。可是不限於此，例如補強區域21的下端21a也僅在吸收性芯61的橫向中的一部分的區域較補強薄片30的下端30a更位於下方側。又，補強區域21的全部也可與補強薄片30重疊。 Fig. 7A is a plan view of a part of the diaper 1 of the fourth embodiment, and Fig. 7B is a cross-sectional view of the diaper 1 of the fourth embodiment. In the paper diaper 1 of the fourth embodiment, as shown in FIG. 7A, the lower end 21a of the reinforced region 21 is not bent in the horizontal direction. In addition, the lower end 21a of the reinforcing region 21 is positioned below the lower end 30a of the reinforcing sheet 30 in the longitudinal direction in the entire horizontal direction. side. At this time, as in the first embodiment, as shown in FIG. 7B, a plurality of regions A1' to A4' with different rigidities of the absorbent body 2 can be provided around the upper end of the absorbent core 61, so that the wear time can be reduced. Of discomfort. However, it is not limited to this. For example, the lower end 21a of the reinforcing region 21 is also located on the lower side of the lower end 30a of the reinforcing sheet 30 only in a part of the area in the lateral direction of the absorbent core 61. In addition, the entire reinforcement area 21 may overlap with the reinforcement sheet 30.

===第5實施形態=== ===Fifth Embodiment ===

圖8，是第5實施形態的紙尿褲1的剖視圖。第5實施形態，是將提高吸收性芯61的上端部的剛性的補強手段設成與補強薄片30不同的補強薄片22，並在縱向中的吸收性芯61的上端部的位置設置不同的補強薄片22。例如，如圖8所示，在吸收性芯61的上端部的非肌膚側面可用接著劑等接合不同的補強薄片22。此時，提高吸收性芯61的上端周邊中的吸收性本體2的剛性，也可維持吸收性本體2的平面狀態，可抑制來自皺紋的***物的漏出等。此外，只要在縱向中的吸收性芯61的上端部的位置設置不同的補強薄片22即可，不同的補強薄片22的厚度方向的位置並沒有被限制，在吸收性芯61、芯包層薄片62不限於接合不同的補強薄片22。又，除了壓縮吸收性芯61的上端部，也可設置不同的補強薄片22。 Fig. 8 is a cross-sectional view of the diaper 1 according to the fifth embodiment. In the fifth embodiment, the reinforcing means for increasing the rigidity of the upper end of the absorbent core 61 is provided as a reinforcing sheet 22 different from the reinforcing sheet 30, and different reinforcing is provided at the position of the upper end of the absorbent core 61 in the longitudinal direction.片22。 Sheet 22. For example, as shown in FIG. 8, the non-skin side surface of the upper end part of the absorptive core 61 can join the different reinforcing sheet 22 with an adhesive agent etc.. At this time, the rigidity of the absorptive main body 2 in the periphery of the upper end of the absorptive core 61 is increased, the planar state of the absorptive main body 2 can be maintained, and the leakage of excrement from wrinkles can be suppressed. In addition, as long as the position of the upper end portion of the absorbent core 61 in the longitudinal direction is different, the position of the different reinforcing sheet 22 in the thickness direction is not limited. The absorbent core 61, the core-cladding sheet 62 is not limited to joining different reinforcing sheets 22. In addition to compressing the upper end of the absorbent core 61, different reinforcing sheets 22 may be provided.

===其他的實施形態=== ===Other implementation forms===

上述實施形態，雖在褲型狀態的紙尿褲1的前後方向兩方(腹側及背側)設有補強區域21(補強手段20)、補強薄片30，可是不限於此，也可僅設在任一方。 In the above-mentioned embodiment, although the trouser-shaped diaper 1 is provided with reinforcing regions 21 (reinforcing means 20) and reinforcing sheets 30 in both the front and rear directions (ventral side and back side), it is not limited to this, and may be provided on either side. .

上述實施形態，雖在液透過性薄片5與吸收性芯6之間設有補強薄片30，可是不限於此。例如，補強薄片30也可較吸收性芯6更被設在非肌膚側。此時，在補強薄片30施予顏色、文字、花樣等，可從紙尿褲1外視認補強薄片30，來增加紙尿褲1的設計性。又，讓補強薄片30的顏色等在腹側與背側不同，使紙尿褲1的前後判斷變的容易。又，例如將腹側的補強薄片30配置在比吸收性芯61更位於肌膚側，將背側的補強薄片30配置在比吸收性芯61更位於非肌膚側等，在腹側與背側因補強薄片30讓厚度方向的位置不同。此時，紙尿褲1的前後判斷也變的容易。又，也可將腹側與背側的補強薄片30一起配置在比液透過性薄片5更位於肌膚側。此時，在補強薄片30與液透過性薄片5之間，設置朝縱向下方開口的空間，可在其空間接住***物。又，將與紙尿布1不同的帶狀的吸收墊片的端部***前述空間可固定吸收墊片。 In the above-mentioned embodiment, the reinforcing sheet 30 is provided between the liquid-permeable sheet 5 and the absorbent core 6, but it is not limited to this. For example, the reinforcing sheet 30 may be provided on the non-skin side than the absorbent core 6. At this time, colors, characters, patterns, etc. are applied to the reinforcing sheet 30, so that the reinforcing sheet 30 can be seen from the outside of the diaper 1 to increase the design of the diaper 1. In addition, the color of the reinforcing sheet 30 is made different on the ventral side and the back side, which makes it easier to judge the front and back of the diaper 1. In addition, for example, the reinforcing sheet 30 on the ventral side is arranged on the skin side than the absorbent core 61, and the reinforcing sheet 30 on the back side is arranged on the non-skin side than the absorbent core 61. The reinforcing sheet 30 has different positions in the thickness direction. At this time, the front and back judgment of the diaper 1 also becomes easy. In addition, the reinforcing sheet 30 on the ventral side and the back side may be arranged on the skin side than the liquid-permeable sheet 5 together. At this time, between the reinforcing sheet 30 and the liquid-permeable sheet 5, a space that is opened vertically downward is provided, and excrement can be caught in the space.
