特許第5843598号公報Japanese Patent No. 5842598
 着用者が、特許文献1に記載された吸収性物品を着用したとき、着用者の排泄口に対向する股下域は、着用者の両脚の間に挟まれる。このときに、吸収体の目付が高い中高部を股下域に設けたり、中高部を挟んで両側に一対の圧搾溝を設けたりすることにより、吸収性物品が着用者の排泄口にフィットし易くなっている。 When the wearer wears the absorbent article described in Patent Document 1, the crotch region facing the wearer's excretion opening is sandwiched between the wearer's legs. At this time, it is easy to fit the absorbent article to the wearer's excretion opening by providing a mid-high portion with a high basis weight of the absorbent body in the crotch region or by providing a pair of squeezing grooves on both sides across the mid-high portion. It has become.
 しかしながら、本願の発明者は、このような吸収性物品について以下のような課題を発見した。吸収性物品は、使用前には概ね平らな状態であるが、使用時には下着に沿って前後方向に湾曲した状態になる。使用時における前後方向の湾曲によって、吸収体の一部が着用者の肌から離れるような歪みが生じることがある。この吸収体の歪みは、排泄口対向領域の後側で最も着用者の身体の曲率の高い領域、具体的には着用者の会陰部に対向する領域に生じ易い。この歪みのせいで吸収体と会陰部との間に隙間が生じることがあり、経血のような体液が、この隙間の領域で着用者の脚を伝って吸収性物品の幅方向へ流れ、吸収性物品の側方へ漏れてしまうことがある。 However, the inventor of the present application has discovered the following problems regarding such an absorbent article. The absorbent article is generally flat before use, but is curved in the front-rear direction along the underwear during use. Due to the bending in the front-rear direction at the time of use, a distortion may occur in which a part of the absorbent body is separated from the wearer's skin. This distortion of the absorber is likely to occur in the region having the highest curvature of the wearer's body, specifically in the region facing the perineum of the wearer, on the rear side of the excretory opening facing region. Due to this distortion, there may be a gap between the absorbent body and the perineum, and body fluid such as menstrual blood flows in the width direction of the absorbent article along the leg of the wearer in the area of this gap, It may leak to the side of the absorbent article.
 したがって、排泄口対向領域の後側、具体的には着用者の会陰部に対向する領域におけるフィット性をより向上させることができる吸収性物品が望まれる。 Therefore, an absorbent article that can further improve the fit in the rear side of the excretory opening facing region, specifically in the region facing the perineum of the wearer is desired.
 一態様に係る吸収性物品は、互いに直交する前後方向及び幅方向と、吸収体と、少なくとも前記吸収体に形成された圧搾部と、を備えた吸収性物品であって、前記圧搾部は、着用者の排泄口に対向する領域である排泄口対向領域の後側の領域に、前側又は後側へ向かうにつれて前記幅方向における外側へ延びる複数の第1圧搾部を有し、前記複数の第1圧搾部は、前記幅方向における前記吸収性物品の中心を通る中心線を挟んで両側に配置されており、前記前後方向に並んで配置されており、前記複数の第1圧搾部は、着用者の会陰部に対向する領域である会陰部対向領域に設けられている。 The absorbent article which concerns on 1 aspect is an absorbent article provided with the front-back direction and the width direction which mutually orthogonally cross, an absorber, and the pressing part formed in the said absorber at least, Comprising: The said pressing part is In the rear region of the excretion port facing region, which is a region facing the excretion port of the wearer, has a plurality of first pressing portions extending outward in the width direction as going to the front side or the rear side, 1 compression part is arrange | positioned on both sides across the centerline which passes along the center of the said absorbent article in the said width direction, is arrange | positioned along with the said front-back direction, and these 1st compression parts are worn It is provided in the perineum facing region, which is a region facing the perineum of the person.

 (1)実施形態の概要
 本明細書及び添付図面の記載により、少なくとも以下の事項が明らかとなる。
(1) Outline of Embodiments At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
 一態様に係る吸収性物品は、互いに直交する前後方向及び幅方向と、吸収体と、少なくとも前記吸収体に形成された圧搾部と、を備え、前記圧搾部は、着用者の排泄口に対向する領域である排泄口対向領域の後側の領域に、前側又は後側へ向かうにつれて前記幅方向における外側へ延びる複数の第1圧搾部を有し、前記複数の第1圧搾部は、前記幅方向における前記吸収性物品の中心を通る中心線を挟んで両側に配置されており、前記前後方向に並んで配置されており、前記複数の第1圧搾部は、着用者の会陰部に対向する領域である会陰部対向領域に設けられている。 The absorbent article which concerns on 1 aspect is equipped with the front-back direction and the width direction which are mutually orthogonal, an absorber, and the pressing part formed in the said absorber at least, The said pressing part opposes a wearer's excretion opening | mouth A plurality of first pressing portions extending outward in the width direction toward the front side or the rear side in the region on the rear side of the excretion opening facing region, which is a region to perform, wherein the plurality of first pressing portions have the width It is arrange | positioned on both sides across the centerline which passes along the center of the said absorbent article in a direction, is arrange | positioned along with the said front-back direction, and these 1st pressing parts oppose a wearer's perineum part. It is provided in the perineum facing region that is the region.
 吸収性物品の排泄口対向領域は、着用中に着用者の両脚に挟まることによって比較的高い剛性になるとともに、着用者の排泄口にフィットするように構成されている。このような状態で、吸収性物品は、着用者の身体の湾曲に沿って前後方向にも湾曲される。 The region opposite to the excretion port of the absorbent article is configured to be relatively high rigidity by being sandwiched between both legs of the wearer during wearing, and to fit the excretion port of the wearer. In such a state, the absorbent article is also curved in the front-rear direction along the curve of the wearer's body.
 上記態様によれば、吸収性物品の幅方向内側へ向かう力は、中心線を挟んで両側に配置された一対の第1圧搾部へ伝わる。各々の第1圧搾部は、前側又は後側へ向かうにつれて幅方向における外側へ延びているため、第1圧搾部の外側部分へ伝わった力は第1圧搾部に沿って幅方向の内側へ向かう。そのため、中心線を挟んで両側に配置された一対の第1圧搾部の幅方向の内側の端部どうし結ぶ仮想折線(図1の符号FL参照)上に力が加わり、その結果、吸収性物品は、仮想折線を基点に前後方向に曲がり易くなる。 According to the said aspect, the force which goes to the width direction inner side of an absorbent article is transmitted to a pair of 1st pressing part arrange | positioned on both sides on both sides of a centerline. Since each 1st pressing part is extended to the outer side in the width direction as it goes to the front side or the back side, the force transmitted to the outer side part of the 1st pressing part goes to the inner side of the width direction along the 1st pressing part. . Therefore, a force is applied to a virtual fold line (see symbol FL in FIG. 1) connecting the inner ends in the width direction of the pair of first pressing portions arranged on both sides across the center line. As a result, the absorbent article Is easy to bend in the front-rear direction with the virtual broken line as a base point.
 複数の第1圧搾部が前後方向に複数並んでいるので、上記の仮想折線は、排泄口対向領域の後側の領域に複数形成される。この複数の仮想折線を基点に前後方向に吸収体が徐々に曲がるため、吸収体に意図しない大きな歪が生じ難い。その結果、着用者の肌と吸収体との間に隙間が生じ難く、排泄口対向領域の後側の領域におけるフィット性をより向上させることができる。 Since a plurality of first pressing parts are arranged in the front-rear direction, a plurality of the above-mentioned virtual folding lines are formed in the rear side area of the excretory opening facing area. Since the absorber gradually bends in the front-rear direction with the plurality of virtual broken lines as base points, large unintended distortion is unlikely to occur in the absorber. As a result, it is difficult for a gap to be generated between the wearer's skin and the absorbent body, and the fit in the rear region of the excretory opening facing region can be further improved.
 特に、会陰部対向領域は、着用者の会陰部、すなわち膣口と肛門との間の領域に相当する。着用者の会陰部は、前後方向における着用者の身体の湾曲が大きい領域に相当する。この領域に複数の第1圧搾部が設けられていることで、複数の仮想折線が会陰部対向領域に形成されることになる。これにより、会陰部対向領域において、複数の仮想折線を基点に前後方向に吸収体が徐々に曲がるため、会陰部対向領域におけるフィット性をより向上させることができる。 In particular, the perineum facing region corresponds to the perineum of the wearer, that is, the region between the vaginal opening and the anus. The perineum part of the wearer corresponds to a region where the wearer's body is curved in the front-rear direction. By providing a plurality of first pressing parts in this region, a plurality of virtual folding lines are formed in the perineum region facing region. Thereby, in an perineum part opposing area | region, since an absorber gradually bends in the front-back direction on the basis of several virtual folding lines, the fitting property in a perineum part opposing area | region can be improved more.
 好ましい一態様によれば、前記複数の第1圧搾部は前記前後方向に互いに連結している。 According to a preferred aspect, the plurality of first compressed parts are connected to each other in the front-rear direction.
 前後方向において第1圧搾部どうしの間にギャップが存在すると、そのギャップのところで吸収体が意図せず大きく歪んでしまう可能性がある。複数の第1圧搾部が前後方向に互いに連結しているので、このような吸収体の意図しない歪みを抑制することができ、前述の仮想折線のところで吸収体を意図的に曲げ易くなる。 If there is a gap between the first compressed parts in the front-rear direction, the absorbent body may be unintentionally distorted at the gap. Since the several 1st pressing part is mutually connected in the front-back direction, the distortion which such an absorber does not intend can be suppressed, and it becomes easy to bend an absorber intentionally in the above-mentioned virtual broken line.
 好ましい一態様によれば、前記複数の第1圧搾部の各々は、前記幅方向における外側へ向かうとともに曲線的に湾曲している。 According to a preferred aspect, each of the plurality of first pressing portions is curved in a curved manner toward the outside in the width direction.
 会陰部対向領域は、着用者の両脚に挟まれる領域に位置する。会陰部対向領域に設けられた第1圧搾部が幅方向における外側に直線的に延びていると、比較的剛性の高い第1圧搾部の外側端部が着用者の両脚に強く圧力を与えることがある。本態様では、複数の第1圧搾部の各々が幅方向における外側へ向かうとともに曲線的に湾曲しているため、着用者の両脚に与えられる圧力が緩和され、吸収性物品の履き心地を良くすることができる。 The perineum facing region is located in the region sandwiched between the wearer's legs. When the first squeezing part provided in the perineum facing region extends linearly outward in the width direction, the outer end of the first squeezing part having relatively high rigidity strongly applies pressure to the wearer's legs. There is. In this aspect, since each of the plurality of first pressing parts goes outward in the width direction and is curved in a curved manner, the pressure applied to both legs of the wearer is relieved, and the comfort of the absorbent article is improved. be able to.
 好ましい一態様によれば、前記幅方向における前記複数の第1圧搾部どうしの間の領域は、前記幅方向における前記複数の第1圧搾部よりも外側に位置する前記吸収体の領域よりも低い剛性を有する低剛性領域を有する。 According to one preferable aspect, the area | region between these 1st pressing parts in the said width direction is lower than the area | region of the said absorber located outside the said several 1st pressing parts in the said width direction. It has a low rigidity region having rigidity.
 複数の第1圧搾部どうしの間に低剛性領域が存在することにより、複数の第1圧搾部どうしの間の領域が、着用者の会陰部又は肛門の方に向けて突出するように変形し易くなる。これにより、排泄口対向領域の後側の領域におけるフィット性を向上させることができる。 Due to the presence of the low-rigidity region between the plurality of first pressing parts, the region between the plurality of first pressing parts is deformed so as to protrude toward the wearer's perineum or anus. It becomes easy. Thereby, the fitting property in the area | region of the back side of an excretion mouth opposing area | region can be improved.
 また、このように、排泄口対向領域の後側の領域を着用者の会陰部又は肛門の方に向けて突出させた場合であっても、前述した複数の仮想折線を基点に吸収体が前後方向に徐々に曲がり易くなっているので、意図しない大きな歪に起因するフィット性の低下を抑制することができる。 Further, in this way, even when the rear region of the excretory opening facing region is protruded toward the wearer's perineum or anus, the absorbent body moves back and forth based on the plurality of virtual folding lines described above. Since it becomes easy to bend gradually in the direction, it is possible to suppress a decrease in fit due to a large unintended distortion.
 好ましい一態様によれば、前記低剛性領域は、前記複数の第1圧搾部どうしの間の領域よりも後方へ延びており、前記圧搾部は、前記複数の第1圧搾部よりも後側で、前記低剛性領域を挟んで両側に配置された第3圧搾部を有する。 According to a preferred aspect, the low-rigidity region extends rearward from a region between the plurality of first pressing portions, and the pressing portion is located behind the plurality of first pressing portions. And a third pressing part disposed on both sides of the low-rigidity region.
 第3圧搾部が吸収体の曲げ基点になっており、かつ低剛性領域が複数の第1圧搾部どうしの間の領域よりも後方へ延びている。これにより、着用者の臀裂に向かって吸収体が突出し易くなる。これにより、排泄口対向領域から後側域にわたって、吸収体が着用者の肌にフィットし易くなる。 The third pressing part is the bending base point of the absorber, and the low-rigidity area extends rearward from the area between the plurality of first pressing parts. Thereby, an absorber becomes easy to protrude toward a wearer's crack. Thereby, an absorber becomes easy to fit a wearer's skin over a rear side area from an excretion mouth opposing field.
 好ましい一態様によれば、前記低剛性領域は、前記幅方向における前記複数の第1圧搾部よりも外側に位置する前記吸収体の目付よりも低い目付を有する前記吸収体によって構成される。吸収体の目付の調節によって低剛性領域を容易に形成することができる。 According to a preferred aspect, the low-rigidity region is configured by the absorbent body having a basis weight lower than the basis weight of the absorbent body positioned outside the plurality of first compressed portions in the width direction. The low rigidity region can be easily formed by adjusting the basis weight of the absorber.
 好ましい一態様によれば、前記幅方向における前記排泄口対向領域の中央に、前記幅方向における前記排泄口対向領域の端部の前記吸収体の目付よりも高い目付を有する高目付領域が設けられている。 According to a preferred aspect, a high-weight area having a higher weight per unit area than the weight of the absorber at the end of the excretion-facing area in the width direction is provided in the center of the excretion-facing area in the width direction. ing.
 吸収性物品の排泄口対向領域は、着用中に着用者の両脚に挟まることによって幅方向の内側へ力を受ける。この力により、比較的高い剛性の高目付領域が着用者の排泄口に向けて変形する。 The excretion opening facing region of the absorbent article receives a force inward in the width direction by being sandwiched between both legs of the wearer during wearing. Due to this force, the high-weight area with relatively high rigidity is deformed toward the excretion opening of the wearer.
 好ましい一態様によれば、前記圧搾部は、前記中心線を挟んで両側に、前記前後方向に延びる一対の第2圧搾部を前記排泄口対向領域に有する。 According to a preferred aspect, the squeezing portion has a pair of second squeezing portions extending in the front-rear direction on both sides of the center line in the excretory opening facing region.
 一対の第2圧搾部は吸収体の変形基点になるため、着用者の両脚から幅方向の内側へかかる力によって、一対の第2圧搾部によって挟まれた領域が着用者の肌に向かって凸に変形し易くなる。これにより、排泄口対向領域におけるフィット性を向上させることができる。 Since the pair of second pressing parts serves as a deformation starting point of the absorbent body, the region sandwiched between the pair of second pressing parts protrudes toward the wearer's skin by the force applied to the inner side in the width direction from both legs of the wearer. It becomes easy to deform. Thereby, the fitting property in an excretion mouth opposing area | region can be improved.
 好ましい一態様によれば、前記複数の第1圧搾部の前側の端部は、前記第2圧搾部の後側の端部よりも、前記幅方向における内側に配置されている。 According to a preferred embodiment, the front end of the plurality of first pressing parts is arranged on the inner side in the width direction than the rear end of the second pressing part.
 着用者の両脚から幅方向の内側へ向けた力は第2圧搾部にかかり易い。第1圧搾部の前側の端部が第2圧搾部の後側の端部よりも幅方向における内側に配置されているため、第2圧搾部にかかった力が、第1圧搾部へ伝わり易くなる。これにより、第1圧搾部から第2圧搾部にわたる領域において、吸収体が着用者の肌に向かって凸に変形し、この凸状の吸収体が意図しない形状に崩れることなく上記の仮想折線が形成されるようになる。したがって、吸収体の凸状の変形を意図しないように崩すことなく複数の仮想折線を基点に前後方向に吸収体が徐々に曲がり易くなる。 The force directed from the wearer's legs toward the inside in the width direction is likely to be applied to the second pressing portion. Since the end on the front side of the first pressing part is arranged on the inner side in the width direction than the end on the rear side of the second pressing part, the force applied to the second pressing part is easily transmitted to the first pressing part. Become. Thereby, in the area | region ranging from a 1st pressing part to a 2nd pressing part, an absorber deform | transforms convex toward a wearer's skin, and said virtual folding line does not collapse into the shape which this convex absorber does not intend. Will be formed. Therefore, the absorber is likely to bend gradually in the front-rear direction based on a plurality of virtual broken lines without unintentionally deforming the convex shape of the absorber.
 好ましい一態様によれば、吸収性物品は、前記吸収性物品を下着に固定する接合部を有し、前記複数の第1圧搾部の少なくとも1つは、厚み方向において前記接合部と重ならない領域に配置されている。 According to a preferred aspect, the absorbent article has a joint that fixes the absorbent article to underwear, and at least one of the plurality of first pressing parts is a region that does not overlap the joint in the thickness direction. Is arranged.
 上記態様により、吸収体を意図的に変形させるための上述の複数の仮想折線のうちの少なくとも1つが、接合部と重ならない領域に配置される。したがって、仮想折線に起因する吸収体の意図的な変形が、接合部を介して下着に拘束され難くなっている。よって、仮想折線を基点に前後方向に吸収体を徐々により曲がり易くすることができる。 According to the above aspect, at least one of the plurality of virtual broken lines for intentionally deforming the absorber is disposed in a region that does not overlap the joint. Therefore, the intentional deformation of the absorber due to the virtual broken line is less likely to be restrained by the undergarment via the joint. Accordingly, the absorber can be gradually bent more easily in the front-rear direction with the virtual broken line as a base point.

 図2に示すように、非肌面シート20の非肌対向面には、吸収性物品1を下着に接合するための接合部60が設けられていてよい。接合部60は、吸収体30と重なる領域に配置された本体接合部61と、ウイング3に配置されたウイング接合部62と、ヒップフラップ4に配置されたフラップ接合部63と、を有する。 As shown in FIG. 2, a non-skin facing surface of the non-skin surface sheet 20 may be provided with a joint 60 for joining the absorbent article 1 to the underwear. The joint portion 60 includes a main body joint portion 61 disposed in a region overlapping the absorber 30, a wing joint portion 62 disposed in the wing 3, and a flap joint portion 63 disposed in the hip flap 4.
 本体接合部61は、幅方向Wにおける吸収体30の中心と重ならないように配置されていてよい。本体接合部61は、幅方向Wに離間して複数設けられていてよい。各々の本体接合部61は、前後方向Lに沿って延びていて良い。 The main body joint portion 61 may be disposed so as not to overlap the center of the absorber 30 in the width direction W. A plurality of main body joint portions 61 may be provided apart from each other in the width direction W. Each main body joint portion 61 may extend along the front-rear direction L.
 吸収体30は、吸収材料の目付が異なる複数の領域を有する。吸収体30は、少なくとも、高目付領域31と、低目付領域32と、第1側部領域33と、第2側部領域34と、を有する。高目付領域31及び低目付領域32は、吸収体30の幅方向Wの中央に設けられている。第1側部領域33は、幅方向Wにおいて高目付領域31の両外側に位置する。第2側部領域34は、幅方向Wにおいて低目付領域32の両外側に位置する。 The absorber 30 has a plurality of regions with different basis weights of the absorbent material. The absorber 30 includes at least a high weight area 31, a low weight area 32, a first side area 33, and a second side area 34. The high weight area 31 and the low weight area 32 are provided in the center of the absorbent body 30 in the width direction W. The first side region 33 is located on both outer sides of the high weight area 31 in the width direction W. The second side area 34 is located on both outer sides of the low weight area 32 in the width direction W.
 高目付領域31は、幅方向Wにおける排泄口対向領域S1の中央に設けられる。さらに、高目付領域31は、前後方向Lにおけるウイングの中心を通り、幅方向Wに延びるウイング中心線3CLに配置されている。高目付領域31は、着用時に排泄口(膣口)に対向して配置される。高目付領域31全体が排泄口当接域S1に設けられていてよい。高目付領域31の吸収材料の目付は、幅方向Wにおける排泄口対向領域S1の端部の吸収体30の目付よりも高い目付を有する。より具体的には、高目付領域31の吸収材料の目付は、周囲の領域(低目付領域32及び第1側部領域33)の吸収材料の目付よりも高い。高目付領域31は、周囲の領域(低目付領域32及び第1側部領域33)よりも厚く構成されていてもよい。これにより、排泄口当接域S1が着用者の膣口に対してフィットし易くなる。 The high basis weight area 31 is provided in the center of the excretion opening facing area S1 in the width direction W. Further, the high basis weight region 31 is disposed on a wing center line 3CL that passes through the center of the wing in the front-rear direction L and extends in the width direction W. The high weight area 31 is disposed to face the excretion opening (vaginal opening) when worn. The entire high weight area 31 may be provided in the excretion opening contact area S1. The basis weight of the absorbent material in the high basis weight region 31 has a basis weight higher than the basis weight of the absorber 30 at the end of the excretory opening facing region S1 in the width direction W. More specifically, the weight of the absorbent material in the high weight area 31 is higher than the weight of the absorbent material in the surrounding areas (the low weight area 32 and the first side area 33). The high weight area 31 may be configured to be thicker than the surrounding areas (the low weight area 32 and the first side area 33). Thereby, the excretion opening contact area S1 is easily fitted to the wearer's vaginal opening.
 低目付領域32は、高目付領域31の後側に配置されている。低目付領域32の吸収材料の目付は、幅方向Wにおける後述の複数の第1圧搾部81よりも外側に位置する吸収体30の目付よりも低い目付を有する吸収体30によって構成される。より具体的には、低目付領域32は、周囲の領域(高目付領域31及び第2側部領域34)の吸収材料の目付よりも低い。低目付領域32は、少なくとも会陰部当接域S4と後側域S3とにわたって延びている。このような構成によれば、低目付領域32と周囲の領域との剛性差が顕著になり、着用時に容易に変形して、低目付領域32が着用者の臀部の亀裂に向かって隆起し易くなる。 The low weight area 32 is disposed on the rear side of the high weight area 31. The basis weight of the absorbent material in the low basis weight region 32 is configured by the absorbent body 30 having a lower basis weight than the basis weight of the absorbent body 30 positioned outside a plurality of first pressing portions 81 described later in the width direction W. More specifically, the low weight area 32 is lower than the weight of the absorbent material in the surrounding areas (the high weight area 31 and the second side area 34). The low weight area 32 extends over at least the perineum area contact area S4 and the rear side area S3. According to such a configuration, the difference in rigidity between the low weight area 32 and the surrounding area becomes significant, and the low weight area 32 is easily deformed at the time of wearing, and the low weight area 32 is easily raised toward the crack of the wearer's buttocks. Become.
 高目付領域31の幅方向の長さは、低目付領域32の幅方向の長さよりも長い。股下域S1の中央に位置する高目付領域31の幅方向の長さが低目付領域32の幅方向の長さよりも長いため、高目付領域31において広い幅で体液を吸収できる。一方、低目付領域32の幅方向の長さが高目付領域31の幅方向の長さよりも短いため、着用者側に隆起する領域が狭い幅となり、着用者の会陰部にフィットし易くなる。 The length in the width direction of the high weight area 31 is longer than the length in the width direction of the low weight area 32. Since the length in the width direction of the high weight area 31 located at the center of the crotch area S1 is longer than the length in the width direction of the low weight area 32, the body weight can be absorbed in a wide width in the high weight area 31. On the other hand, since the length in the width direction of the low weight area 32 is shorter than the length in the width direction of the high weight area 31, the area that protrudes toward the wearer has a narrow width and is easily fitted to the perineum of the wearer.
 吸収性物品は、少なくとも吸収体30に形成された圧搾部80を有する。圧搾部80は、複数の第1圧搾部81と、第2圧搾部82と、第3圧搾部83と、を有する。 The absorbent article has at least a pressing part 80 formed in the absorbent body 30. The pressing unit 80 includes a plurality of first pressing units 81, a second pressing unit 82, and a third pressing unit 83.
 複数の第1圧搾部81は、排泄口対向領域S1の後側の領域に設けられ、前側又は後側へ向かうにつれて幅方向Wにおける外側へ延びる。複数の第1圧搾部81は、幅方向Wにおける吸収性物品1の中心を通る中心線CLを挟んで両側に配置されており、前後方向Lに並んで配置されている。複数の第1圧搾部81は、着用者の会陰部に対向する領域である会陰部対向領域S4に設けられている。なお、各々の第1圧搾部81のうちの少なくとも一部が、前側又は後側へ向かうにつれて幅方向Wにおける外側へ延びていればよい。 The plurality of first pressing portions 81 are provided in the rear region of the excretion opening facing region S1, and extend outward in the width direction W toward the front side or the rear side. The plurality of first pressing parts 81 are arranged on both sides with a center line CL passing through the center of the absorbent article 1 in the width direction W, and are arranged side by side in the front-rear direction L. The several 1st pressing part 81 is provided in perineum part opposing area | region S4 which is an area | region facing a wearer's perineum part. In addition, at least one part of each 1st pressing part 81 should just extend to the outer side in the width direction W as it goes to the front side or the rear side.
 好ましくは、図1に示すように、複数の第1圧搾部81は前後方向Lに互いに連結している。この場合であっても、前側又は後側へ向かうにつれて幅方向Wにおける外側へ延びる第1圧搾部81の部分が、前後方向Lに複数並んでいることに留意されたい。 Preferably, as shown in FIG. 1, the plurality of first pressing portions 81 are connected to each other in the front-rear direction L. Even in this case, it should be noted that a plurality of portions of the first pressing portion 81 extending outward in the width direction W are arranged in the front-rear direction L toward the front side or the rear side.
 好ましくは、複数の第1圧搾部81の各々は、幅方向Wにおける外側へ向かうとともに曲線的に湾曲している。会陰部対向領域S4は、着用者の両脚に挟まれる領域に位置する。会陰部対向領域S4に設けられた第1圧搾部81が幅方向Wにおける外側に直線的に延びていると、比較的剛性の高い第1圧搾部81の外側端部が着用者の両脚に強く圧力を与えることがある。本態様では、複数の第1圧搾部81の各々が幅方向Wにおける外側へ向かうとともに曲線的に湾曲しているため、着用者の両脚に与えられる圧力が緩和され、吸収性物品の履き心地を良くすることができる。 Preferably, each of the plurality of first squeezing portions 81 is curved in a curved manner toward the outside in the width direction W. The perineum facing region S4 is located in a region sandwiched between both legs of the wearer. When the 1st pressing part 81 provided in perineum part opposing area | region S4 has extended linearly in the outer side in the width direction W, the outer side edge part of the 1st pressing part 81 with comparatively high rigidity is strong to a wearer's both legs. May give pressure. In this aspect, since each of the plurality of first squeezing parts 81 goes outward in the width direction W and is curved in a curved manner, the pressure applied to both legs of the wearer is relieved, and the comfort of the absorbent article is reduced. Can be better.
 好ましくは、複数の第1圧搾部81の少なくとも1つは、厚み方向において接合部80と重ならない領域に配置されている。より好ましくは、複数の第1圧搾部81が、厚み方向において接合部80と重ならない領域に配置される。 Preferably, at least one of the plurality of first pressing parts 81 is arranged in a region that does not overlap with the joint part 80 in the thickness direction. More preferably, the plurality of first pressing parts 81 are arranged in a region that does not overlap with the joint part 80 in the thickness direction.
 好ましくは、幅方向Wにおける複数の第1圧搾部81どうしの間の領域は、幅方向Wにおける複数の第1圧搾部81よりも外側に位置する吸収体30の領域よりも低い剛性を有する低剛性領域を有する。低剛性領域は、例えば、吸収体30の目付を低くすることによって実現することができる。本実施形態では、一例として、低剛性領域は、低目付領域32によって構成されている。したがって、以下では、「低剛性領域」という用語に対しても、「低目付領域」付した符号と同じ符号「32」を付すことがある。 Preferably, the area | region between the some 1st pressing parts 81 in the width direction W has low rigidity lower than the area | region of the absorber 30 located in the outer side rather than the some 1st pressing parts 81 in the width direction W. Has a rigid region. The low rigidity region can be realized, for example, by lowering the basis weight of the absorber 30. In the present embodiment, as an example, the low-rigidity area is configured by the low weight area 32. Therefore, hereinafter, the term “low-rigidity region” may be denoted by the same reference numeral “32” as the reference numeral “low-weight area”.
 好ましくは、低剛性領域32は、複数の第1圧搾部81どうしの間の領域よりも後方へ延びている。低剛性領域32は、後述の第3圧搾部83よりもさらに後方まで延びていてよい。 Preferably, the low-rigidity region 32 extends rearward from the region between the plurality of first compressed parts 81. The low-rigidity region 32 may extend further to the rear than a third pressing portion 83 described later.
 第2圧搾部82は、排泄口対向領域S1に設けられている。第2圧搾部82は、中心線CLを挟んで両側に設けられており、前後方向Lに延びている。高目付領域31は、一対の第2圧搾部82の間に配置されていることが好ましい。また、複数の第1圧搾部81の前側の端部は、第2圧搾部82の後側の端部よりも、幅方向Wにおける内側に配置されていてよい。 The 2nd pressing part 82 is provided in the excretion mouth opposing area | region S1. The 2nd pressing part 82 is provided in the both sides on both sides of the centerline CL, and is extended in the front-back direction L. It is preferable that the high weight area 31 is disposed between the pair of second pressing portions 82. Further, the front end portions of the plurality of first pressing portions 81 may be disposed on the inner side in the width direction W than the rear end portion of the second pressing portion 82.
 第3圧搾部83は、複数の第1圧搾部81よりも後側で、後側域S3に設けられている。第3圧搾部83は、中心線CLを挟んで両側に設けられている。第3圧搾部83は、低剛性領域32を挟んで両側に配置されていてよい。 The third pressing part 83 is provided in the rear side region S3 on the rear side of the plurality of first pressing parts 81. The 3rd pressing part 83 is provided in the both sides on both sides of the centerline CL. The 3rd pressing part 83 may be arrange | positioned on both sides on both sides of the low-rigid area | region 32.
 また、本明細書における「吸収体の目付」の測定は、以下の測定方法によって行われるものとする。 In addition, the measurement of “weight of absorbent” in this specification is performed by the following measurement method.
 吸収性物品がパッケージなどに封入されている場合には、パッケージから取り出し、その状態にて20℃±2℃、相対湿度60%±5%RHの雰囲気下において12時間放置したサンプルを用いる。 If the absorbent article is enclosed in a package or the like, use a sample that is removed from the package and left in that state for 12 hours in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH.
 包装体によって包装された吸収性物品においては包装体を開封し、折り畳まれた吸収性物品を展開して、目付を測定する部分の厚み及び面積を測定する。次いで、目付を測定する部分を吸収性物品から切り出し、切り出した部分の重量を測定する。次いで、切り出した部分から肌面シート及び非肌面シート等、吸収体以外の部分を取り除き、吸収体の重量を測定する。吸収体の重量と、目付を測定する部分の面積とに基づいて目付を算出する。 In the absorbent article packaged by the packaging body, the packaging body is opened, the folded absorbent article is developed, and the thickness and area of the portion where the basis weight is measured are measured. Next, a portion for measuring the basis weight is cut out from the absorbent article, and the weight of the cut out portion is measured. Next, parts other than the absorber, such as a skin sheet and a non-skin sheet, are removed from the cut out part, and the weight of the absorber is measured. The basis weight is calculated based on the weight of the absorber and the area of the portion where the basis weight is measured.
 本明細書における「剛性」は、幅方向に沿う力に対する変形し難さを指標するものであり、剛性が高いほど、曲がり難い。剛性は、吸収体を構成する吸収材料の目付に応じており、目付が高いほど、剛性が高くなる。よって、吸収体の目付を目視等で確認することにより、剛性を確認することができる。また、剛性は、JIS L 1096の測定方法に準拠したガーレー剛性値によって測定することもできる。 “Rigidity” in the present specification indicates the difficulty of deformation with respect to the force along the width direction, and the higher the rigidity, the less likely it is to bend. The rigidity depends on the basis weight of the absorbent material constituting the absorber, and the higher the basis weight, the higher the rigidity. Therefore, the rigidity can be confirmed by visually confirming the basis weight of the absorber. The stiffness can also be measured by a Gurley stiffness value that conforms to the measurement method of JIS L 1096.
 (3)着用時の変形態様
 次いで、着用時の吸収性物品の変形態様について図6~8を参照して詳細に説明する。図6は、図1のA-A線を基準とした着用状態の吸収性物品の断面図である。図7は、図1のC-C線を基準とした着用状態の吸収性物品の断面図である。図8は、着用状態の吸収性物品の前後方向Lに沿った部分的断面図である。図8は、会陰部対向領域S4を示している。
(3) Deformation mode at the time of wearing Next, the deformation mode of the absorbent article at the time of wearing will be described in detail with reference to FIGS. 6 is a cross-sectional view of the absorbent article in a worn state with reference to the line AA in FIG. 7 is a cross-sectional view of the absorbent article in a worn state with reference to the line CC in FIG. FIG. 8 is a partial cross-sectional view along the front-rear direction L of the absorbent article in a worn state. FIG. 8 shows the perineum region facing region S4.
 吸収性物品1は、着用者の両足によって挟まれ、幅方向Wの外側から幅方向Wの内側に向かう力がかかる。吸収性物品1の排泄口対向領域S1は、着用中に着用者の両脚に挟まることによって比較的高い剛性になるとともに、着用者の排泄口にフィットするように構成されている(図6参照)。 The absorbent article 1 is sandwiched between both legs of the wearer, and a force is applied from the outside in the width direction W to the inside in the width direction W. The excretion opening opposing region S1 of the absorbent article 1 is configured to be relatively high in rigidity by being sandwiched between both legs of the wearer during wearing, and to fit the excretion opening of the wearer (see FIG. 6). .
 特に、排泄口対向領域S1に前述の高目付領域31が設けられている場合、比較的高い剛性の高目付領域31が着用者の排泄口に向けて変形し、着用者の排泄口に対するフィット性が向上する。 In particular, when the above-described high weight area 31 is provided in the excretion opening facing area S1, the relatively high rigidity high weight area 31 is deformed toward the wearer's excretion opening, and fit property to the wearer's excretion opening. Will improve.
 さらに、前述の第2圧搾部82が設けられている場合、一対の第2圧搾部82は吸収体30の変形基点になるため、着用者の両脚から幅方向の内側へかかる力によって、一対の第2圧搾部82に挟まれた領域が着用者の肌に向かって凸に変形し易くなる。これにより、排泄口対向領域S1におけるフィット性をさらに向上させることができる。 Furthermore, when the above-mentioned 2nd pressing part 82 is provided, since a pair of 2nd pressing part 82 becomes a deformation | transformation base point of the absorber 30, a pair of force is applied to the inner side of a width direction from a wearer's both legs. The region sandwiched between the second pressing portions 82 is easily deformed convexly toward the wearer's skin. Thereby, the fitting property in the excretion mouth opposing area | region S1 can further be improved.
 上記のような状態で、吸収性物品1は、着用者の身体の湾曲に沿って前後方向Lにも湾曲される(図8参照)。 In the state as described above, the absorbent article 1 is also bent in the front-rear direction L along the curve of the wearer's body (see FIG. 8).
 上記実施形態によれば、吸収性物品1の幅方向内側へ向かう力は、中心線CLを挟んで両側に配置された一対の第1圧搾部81へ伝わる。各々の第1圧搾部81は、前側又は後側へ向かうにつれて幅方向における外側へ延びているため、第1圧搾部81の外側部分へ伝わった力は第1圧搾部81に沿って幅方向Wの内側へ向かう。そのため、中心線CLを挟んで両側に配置された一対の第1圧搾部81の幅方向Wの内側の端部どうし結ぶ仮想折線(図1の符号FL参照)上に強い力が加わり、その結果、吸収性物品1は、仮想折線FLを基点に前後方向Lに曲がり易くなる(図8参照)。 According to the above embodiment, the force toward the inner side in the width direction of the absorbent article 1 is transmitted to the pair of first pressing parts 81 arranged on both sides with the center line CL interposed therebetween. Since each 1st pressing part 81 is extended to the outer side in the width direction as it goes to the front side or the back side, the force transmitted to the outer side part of the 1st pressing part 81 is width direction W along the 1st pressing part 81. Head inside. Therefore, a strong force is applied on a virtual fold line (see symbol FL in FIG. 1) connecting the inner ends of the pair of first pressing portions 81 arranged on both sides with the center line CL interposed therebetween, as a result. In addition, the absorbent article 1 is easily bent in the front-rear direction L with the virtual folding line FL as a base point (see FIG. 8).
 複数の第1圧搾部81が前後方向Lに複数並んでいるので、上記の仮想折線FLは、排泄口対向領域S1の後側の領域に複数形成される。この複数の仮想折線を基点に前後方向Lに吸収体30が徐々に曲がるため、吸収体30に意図しない大きな歪が生じ難い。その結果、着用者の肌と吸収体との間に隙間が生じ難く、排泄口対向領域S1の後側の領域におけるフィット性をより向上させることができる。 Since a plurality of first compressed parts 81 are arranged in the front-rear direction L, a plurality of the above-described virtual folding lines FL are formed in the rear region of the excretory opening facing region S1. Since the absorber 30 gradually bends in the front-rear direction L based on the plurality of virtual broken lines, it is difficult for unintended large distortion to occur in the absorber 30. As a result, it is difficult for a gap to be generated between the wearer's skin and the absorbent body, and the fit property in the rear region of the excretion opening facing region S1 can be further improved.
 特に、会陰部対向領域S4は、着用者の会陰部、すなわち膣口と肛門との間の領域に相当する。着用者の会陰部は、前後方向Lにおける着用者の身体の湾曲が大きい領域に相当する。この領域に複数の第1圧搾部81が設けられていることで、複数の仮想折線FLが会陰部対向領域S4に形成されることになる。これにより、会陰部対向領域S4において、複数の仮想折線FLを基点に前後方向Lに吸収体30が徐々に曲がるため、会陰部対向領域S4におけるフィット性をより向上させることができる。 In particular, the perineum facing region S4 corresponds to the perineum of the wearer, that is, the region between the vaginal opening and the anus. The perineal part of the wearer corresponds to a region where the wearer's body is curved in the front-rear direction L. By providing the plurality of first pressing parts 81 in this region, a plurality of virtual folding lines FL are formed in the perineum facing region S4. Thereby, in the perineum part opposing area | region S4, since the absorber 30 bend | curves gradually in the front-back direction L on the basis of several virtual broken line FL, the fitting property in the perineum part opposing area | region S4 can be improved more.
 なお、会陰部対向領域S4におけるフィット性を一層向上させるには、3つ以上の第1圧搾部81が、会陰部対向領域S4内に配置されていることがより好ましい。 In addition, in order to further improve the fit in the perineum part facing region S4, it is more preferable that three or more first pressing parts 81 are arranged in the perineum part facing region S4.
 特に、前述の仮想折線FLが、会陰部対向領域S4に内で5mm以上の間隔を開けて少なくとも2つ、好ましくは3つ並んで形成されるように、第1圧搾部81が、設けられるとよい。このため、第1圧搾部81の幅方向の内側の端点が、会陰部対向領域S4内で5mm以上の間隔を開けて少なくとも2つ、好ましくは3つ並んで形成されるとよい。 In particular, when the first squeezed portion 81 is provided so that the above-mentioned virtual fold line FL is formed in the perineum-facing region S4 with an interval of 5 mm or more therebetween and preferably three in a line. Good. For this reason, the end points on the inner side in the width direction of the first pressing portion 81 may be formed in a line at least two, preferably three, with an interval of 5 mm or more in the perineum facing region S4.
 また、複数の第1圧搾部81どうしの間に低剛性領域32が存在する場合、複数の第1圧搾部81どうしの間の領域が、着用者の会陰部又は肛門の方に向けて突出するように変形し易くなる。これにより、排泄口対向領域S1の後側の領域におけるフィット性をより向上させることができる。また、このように、排泄口対向領域S1の後側の領域を着用者の会陰部又は肛門の方に向けて突出させた場合であっても、前述した複数の仮想折線FLを基点に吸収体30が前後方向Lに徐々に曲がり易くなっているので、意図しない大きな歪に起因するフィット性の低下を抑制することができる。 Moreover, when the low-rigid area | region 32 exists between the some 1st pressing parts 81, the area | region between the some 1st pressing parts 81 protrudes toward a wearer's perineum part or an anus. It becomes easy to deform. Thereby, the fitting property in the area | region of the rear side of the excretion mouth opposing area | region S1 can be improved more. In addition, even when the rear region of the excretory opening facing region S1 is protruded toward the perineum or the anus of the wearer as described above, the absorbent body is based on the plurality of virtual folding lines FL described above. Since 30 gradually bends gradually in the front-rear direction L, it is possible to suppress a decrease in fit due to unintended large distortion.
 また、フィット性のため、複数の第1圧搾部81の前側の端部が第2圧搾部82の後側の端部よりも、幅方向Wにおける内側に配置されていることが好ましい。着用者の両脚から幅方向の内側へ向けた力は第2圧搾部82にかかり易い。第1圧搾部81の前側の端部が第2圧搾部82の後側の端部よりも幅方向Wにおける内側に配置されているため、第2圧搾部82にかかった力が、第1圧搾部81へ伝わり易くなる。これにより、第1圧搾部81から第2圧搾部82にわたる領域において、吸収体30が着用者の肌に向かって凸に変形し、この凸状の吸収体30が意図しない形状に崩れることなく上記の仮想折線FLが形成されるようになる。したがって、吸収体30の凸状の変形を意図しないように崩すことなく複数の仮想折線FLを基点に前後方向Lに吸収体30が徐々に曲がり易くなる。 Moreover, it is preferable that the edge part of the front side of the some 1st pressing part 81 is arrange | positioned inside the width direction W rather than the edge part of the rear side of the 2nd pressing part 82 for fitting property. The force directed from the wearer's legs toward the inside in the width direction is likely to be applied to the second pressing portion 82. Since the end part of the front side of the 1st pressing part 81 is arranged inside the width direction W rather than the end part of the back side of the 2nd pressing part 82, the force concerning the 2nd pressing part 82 is the 1st pressing part. It becomes easy to be transmitted to the part 81. Thereby, in the area | region ranging from the 1st pressing part 81 to the 2nd pressing part 82, the absorber 30 deform | transforms convexly toward a wearer's skin, and the said convex-shaped absorber 30 does not collapse | crumble in the shape which is not intended. The virtual fold line FL is formed. Therefore, the absorber 30 gradually bends gradually in the front-rear direction L with the plurality of virtual folding lines FL as the base point without breaking the convex shape of the absorber 30 unintentionally.
 また、第1圧搾部81が接合部80と重ならない領域に配置されている場合、吸収体30を意図的に変形させるための上述の複数の仮想折線FLのうちの少なくとも1つが、接合部80と重ならない領域に配置される。したがって、仮想折線FLに起因する吸収体30の意図的な変形が、接合部80を介して下着Sに拘束され難くなっている。よって、仮想折線FLを基点に前後方向Lに吸収体30を徐々により曲がり易くすることができる。 Moreover, when the 1st pressing part 81 is arrange | positioned in the area | region which does not overlap with the junction part 80, at least 1 of the above-mentioned several virtual broken lines FL for changing the absorber 30 intentionally is the junction part 80. It is placed in an area that does not overlap with Therefore, the intentional deformation of the absorbent body 30 due to the imaginary broken line FL is not easily restrained by the undergarment S via the joint 80. Therefore, the absorber 30 can be gradually bent more easily in the front-rear direction L with the virtual folding line FL as a base point.
 さらに、前述の仮想折線FLのところで吸収体30を意図的に曲げ易くするため、複数の第1圧搾部81が前後方向Lに互いに連結していることが好ましい。仮に、前後方向Lにおいて第1圧搾部81どうしの間にギャップが存在すると、そのギャップのところで吸収体30が意図せず大きく歪んでしまう可能性がある。複数の第1圧搾部81が前後方向Lに互いに連結しているので、このような吸収体30の意図しない歪みを抑制することができ、前述の仮想折線FLのところで吸収体30を意図的に曲げ易くなる。 Furthermore, it is preferable that the plurality of first pressing parts 81 are connected to each other in the front-rear direction L so that the absorber 30 can be easily bent intentionally at the virtual folding line FL. If there is a gap between the first pressing parts 81 in the front-rear direction L, the absorber 30 may be unintentionally distorted at the gap. Since the plurality of first pressing parts 81 are connected to each other in the front-rear direction L, such unintended distortion of the absorbent body 30 can be suppressed, and the absorbent body 30 is intentionally formed at the virtual folding line FL described above. It becomes easy to bend.
 また、複数の第1圧搾部81が前後方向Lに互いに連結している場合、前後方向Lに隣接する第1圧搾部81は、幅方向Wにおける内側縁で角度を持って連結していることが好ましい。これにより、中心線CLを挟んで両側に位置する一対の第1圧搾部81の内側縁どうしの間により強い力が働くため、後述する仮想折線FLのところで吸収性物品がより曲がり易くなる。特に、このように前後方向Lに隣接する第1圧搾部81どうしの角度を持った連結部分は、会陰部対向領域S4内で、前後方向Lに少なくとも2つ並んでいることがより好ましい。 Moreover, when the some 1st pressing part 81 mutually connects in the front-back direction L, the 1st pressing part 81 adjacent to the front-back direction L has connected with the angle in the inner edge in the width direction W. Is preferred. Thereby, since stronger force works between the inner edges of a pair of 1st pressing parts 81 located on both sides on both sides of center line CL, an absorptive article becomes easy to bend in the virtual folding line FL mentioned below. In particular, it is more preferable that at least two connecting portions having an angle between the first pressing portions 81 adjacent to each other in the front-rear direction L are arranged in the front-rear direction L within the perineal region facing region S4.
 また、低剛性領域32を挟んで両側に配置された第3圧搾部83が設けられている場合、第3圧搾部83が吸収体30の曲げ基点になる。さらに、低剛性領域32が複数の第1圧搾部81どうしの間の領域よりも後方へ延びていため、着用者の臀裂に向かって吸収体30が突出し易くなる。これにより、排泄口対向領域S1から後側領S3にわたって、吸収体30が着用者の肌にフィットし易くなる(図7も参照)。 Moreover, when the 3rd pressing part 83 arrange | positioned on both sides on both sides of the low-rigid area | region 32 is provided, the 3rd pressing part 83 becomes a bending base point of the absorber 30. FIG. Furthermore, since the low rigidity area | region 32 is extended back rather than the area | region between the some 1st pressing parts 81, the absorber 30 tends to protrude toward a wearer's crack. Thereby, the absorber 30 becomes easy to fit a wearer's skin over the rear side area | region S3 from the excretion mouth opposing area | region S1 (refer also FIG. 7).
