Description

本発明は、生理用ナプキン等の吸収性物品に関する。 The present invention relates to an absorbent article such as a sanitary napkin.

生理用ナプキン、パンティーライナー、失禁パッド等、下着に装着される吸収性物品が知られている。吸収性物品の非肌対向面には、下着に接合するための接合部が設けられている。特許文献１に記載された吸収性物品は、少なくともウイング接合部とヒップフラップ接合部を有する。特許文献１の吸収性物品を装着する際は、下着を体から離した状態でウイング接合部及びヒップフラップ接合部を下着に接合し、下着を介して吸収性物品を引き上げる。 Absorbent articles to be attached to underwear such as sanitary napkins, panty liners, incontinence pads and the like are known. The non-skin facing surface of the absorbent article is provided with a joint for joining to underwear. The absorbent article described in Patent Document 1 has at least a wing joint and a hip flap joint. When wearing the absorbent article of Patent Document 1, the wing joint and the hip flap joint are joined to the underwear while the underwear is separated from the body, and the absorbent article is pulled up through the underwear.

特開２０１１−７２６５１号公報JP 2011-72651 A

一般的に、下着は、伸縮性を有する素材によって構成されており、装着時に着用者の身体に馴染むように伸長する。一方、吸収性物品の全体は、装着時に身体に馴染むように伸長しない。そのため、装着時に吸収性物品と下着とを共に引き上げると、下着だけが伸長し、ウイング接合部及びヒップフラップ接合部にせん断力が生じる。特に、着用者が下着の腰周りを把持して下着を引き上げるため、製品後方に位置するヒップフラップ接合部にせん断力が生じ、ヒップフラップ接合部が下着から離れることがある。ヒップフラップ接合部等の吸収性物品の後側域に位置する接合部が下着から離れると、装着時に吸収性物品の後端縁が肌対向面側に折れ曲がったり、吸収性物品の後側域の位置が幅方向においてずれてしまったりして、着用時の違和感や***物の漏れが生じることがある。 In general, the underwear is made of a stretchable material and extends to fit the wearer's body when worn. On the other hand, the entire absorbent article does not stretch so as to become familiar with the body when worn. Therefore, when the absorbent article and the undergarment are pulled up together during wearing, only the undergarment is stretched and a shearing force is generated at the wing joint and the hip flap joint. In particular, since the wearer holds the underwear around the waist and pulls up the underwear, a shearing force is generated at the hip flap joint located behind the product, and the hip flap joint may be separated from the underwear. When the joint located in the rear area of the absorbent article such as a hip flap joint is separated from the underwear, the rear edge of the absorbent article may be bent to the skin facing surface side when worn, or the rear area of the absorbent article The position may be shifted in the width direction, which may cause a sense of incongruity or leakage of excrement when worn.

そこで、着用時の違和感を抑制し、かつ***物の漏れを抑制できる吸収性物品を提供することを目的とする。 Then, it aims at providing the absorbent article which can suppress the discomfort at the time of wear and can suppress the leakage of excrement.

本開示に係る吸収性物品（吸収性物品１）は、互いに直交する前後方向(前後方向Ｌ)及び幅方向（幅方向Ｗ）と、着用者の股下に配置される中央域（中央域Ｓ１）と、前記中央域の後側に位置する後側域（後側域Ｓ３）と、前記中央域及び前記後側域に配置される吸収体（吸収体３０）と、前記前後方向に伸縮する弾性部材（弾性部材９１）と、吸収性物品の非肌対向面に設けられ、下着に接合するための接合部（接合部６０）と、前記幅方向に延び、かつ前記吸収性物品の肌対向面同士が対向するように折り畳むための折り線（折り線ＦＬ１）と、を有する吸収性物品であって、前記吸収体は、前記中央域と前記後側域の境界に設けられ、かつ前記幅方向に延びる低目付部（低目付部４１）を有し、前記低目付部の目付は、前記中央域の前記前後方向の中心部の目付よりも低く、前記接合部は、前記低目付部よりも前方に位置する第１接合部（第１接合部６１）と、前記低目付部よりも後方に位置する第２接合部（第２接合部６２）と、を有し、前記弾性部材（弾性部材９１）は、前記低目付部又は前記低目付部から前記幅方向の外側に延びる領域を跨いでおり、前記折り線は、前記吸収性物品が展開された展開状態において前記弾性部材の収縮によって前記低目付部が着用者側に***するように、前記低目付部に設けられることを要旨とする。 The absorbent article (absorbent article 1) according to the present disclosure includes a front-rear direction (front-rear direction L) and a width direction (width direction W) that are orthogonal to each other, and a central region (central region S1) that is disposed in the wearer's crotch A rear side region (rear side region S3) located on the rear side of the central region, an absorber (absorber 30) disposed in the central region and the rear side region, and elasticity that expands and contracts in the front-rear direction.

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。 At least the following matters will become apparent from the description of the present specification and the accompanying drawings.

互いに直交する前後方向及び幅方向と、
着用者の股下に配置される中央域と、
前記中央域の後側に位置する後側域と、
前記中央域及び前記後側域に配置される吸収体と、
前記前後方向に伸縮する弾性部材と、
吸収性物品の非肌対向面に設けられ、下着に接合するための接合部と、
前記幅方向に延び、かつ前記吸収性物品の肌対向面同士が対向するように折り畳むための折り線と、を有する吸収性物品であって、
前記吸収体は、前記中央域と前記後側域の境界に設けられ、かつ前記幅方向に延びる低目付部を有し、
前記低目付部の目付は、前記中央域の前記前後方向の中心部の目付よりも低く、
前記接合部は、前記低目付部よりも前方に位置する第１接合部と、前記低目付部よりも後方に位置する第２接合部と、を有し、
前記弾性部材は、前記低目付部又は前記低目付部から前記幅方向の外側に延びる領域を跨いでおり、
前記折り線は、前記吸収性物品が展開された展開状態において前記弾性部材の収縮によって前記低目付部が着用者側に***するように、前記低目付部に設けられる、吸収性物品。 The front-rear direction and the width direction orthogonal to each other;
A central area located in the inseam of the wearer;
A rear side region located on the rear side of the central region;
An absorber disposed in the central region and the rear side region;
An elastic member that expands and contracts in the front-rear direction;
Provided on the non-skin facing surface of the absorbent article, and a joint for joining to the underwear;
A fold line extending in the width direction and folded so that the skin facing surfaces of the absorbent article face each other,
The absorbent body is provided at the boundary between the central region and the rear side region, and has a low weight portion extending in the width direction,
The basis weight of the low basis weight is lower than the basis weight of the central portion in the front-rear direction of the central area,
The joint has a first joint located forward of the low weight per unit and a second joint located rearward of the low perimeter,
The elastic member straddles a region extending outward in the width direction from the low weight part or the low weight part,
The said folding line is an absorbent article provided in the said low fabric weight part so that the said low fabric weight part may protrude to a wearer side by shrinkage | contraction of the said elastic member in the expansion | deployment state which the said absorbent article was expand | deployed.

低目付部は、中央域の前後方向の中心部よりも目付が低く、変形し易い。低目付部又は低目付部から幅方向の外側に延びる領域を弾性部材が跨いでいるため、展開状態において弾性部材が収縮することにより、低目付部の前後方向の長さが短くなるように変形し、低目付部が前後方向に縮んだ状態となる。 The low basis weight has a lower basis weight than the central portion in the front-rear direction of the central area, and is easily deformed. Since the elastic member straddles the low weight part or the region extending from the low weight part to the outside in the width direction, the elastic member contracts in the expanded state, so that the length in the front-rear direction of the low weight part is shortened. In addition, the low basis weight portion is contracted in the front-rear direction.

装着時に吸収性物品は、低目付部が縮んだ状態で第１接合部及び第２接合部を介して下着に固定された後に、下着と共に引き上げられる。このとき、下着の伸長に伴って低目付部の縮んだ領域が延び、下着の変形に追従して吸収性物品が変形する。よって、第１接合部及び第２接合部は、装着時に下着から離れ難く、下着を引き上げる前に固定された位置を維持し易い。装着時に吸収性物品が意図せずに折れ曲がったり、位置がずれたりすることを抑制し、着用時の違和感や***物の漏れを抑制することができる。特に、着用者が下着の腰周りを把持して下着を引き上げた際に、製品後方に位置する第２接合部にせん断力が生じた場合であっても、第２接合部の接合状態を維持でき、装着時に吸収性物品の後端縁が肌対向面側に折れ曲がったり、吸収性物品の後側域の位置が幅方向においてずれたりする不具合を抑制し、着用時の違和感や***物の漏れを抑制できる。 At the time of wearing, the absorbent article is pulled up together with the underwear after being fixed to the underwear through the first joint portion and the second joint portion in a state where the low basis weight portion is contracted. At this time, as the underwear is extended, a region with a low basis weight is contracted, and the absorbent article is deformed following the deformation of the underwear. Therefore, the first joint portion and the second joint portion are unlikely to be separated from the underwear at the time of wearing, and it is easy to maintain a fixed position before pulling up the underwear. It is possible to prevent the absorbent article from being unintentionally bent or displaced from being attached at the time of wearing, and to suppress a sense of incongruity and excrement leakage during wearing. In particular, when the wearer pulls up the underwear by gripping the circumference of the underwear, even if a shearing force is generated at the second joint located at the rear of the product, the joined state of the second joint is maintained. It is possible to suppress problems such as the rear edge of the absorbent article being bent to the skin-facing surface side when worn or the position of the rear side area of the absorbent article being shifted in the width direction. Can be suppressed.

また、展開状態において低目付部が着用者側に***するように低目付部に折り線が設けられているため、低目付部が下着と接合部の接合を阻害せず、吸収性物品の接合位置を維持して、着用時の違和感や***物の漏れを抑制することができる。 Further, since the fold line is provided in the low weight portion so that the low weight portion is raised on the wearer side in the unfolded state, the low weight portion does not hinder the bonding of the underwear and the bonding portion, and the absorbent article is bonded. A position can be maintained and the uncomfortable feeling at the time of wear and the leakage of excrement can be suppressed.

かかる吸収性物品であって、
前記折り線の少なくとも一部は、前記低目付部の前後方向の中心と一致しない位置に設けられることが望ましい。 Such an absorbent article,
It is desirable that at least a part of the fold line is provided at a position that does not coincide with the front-rear direction center of the low weight portion.

このような吸収性物品によれば、折り線が着用者に対して谷折りであるため、低目付部内の折り線に隣接する隣接領域は、展開状態において折り線を基点にして着用者側に***する。折り線は、低目付部の前後方向の中心と一致せずに、低目付部の前後方向の中心に対して前後方向にずれて設けられる。低目付部の前端縁と低目付部の後端縁のうち折り線と離れて配置される側に位置する隣接領域は、吸収性物品の展開状態で、***する前後方向の長さが長くなり、着用者側により***し易くなる。低目付部が下着と接合部の接合を阻害せず、吸収性物品の接合位置を維持して、着用時の違和感や***物の漏れを更に抑制することができる。 According to such an absorbent article, since the fold line is a valley fold with respect to the wearer, the adjacent region adjacent to the fold line in the low weight portion is on the wearer side with the fold line as a base point in the unfolded state. Raise. The fold line does not coincide with the center in the front-rear direction of the low weight portion, and is provided so as to be shifted in the front-rear direction with respect to the center in the front-rear direction of the low weight portion. The adjacent area located on the side of the front edge of the low weight part and the rear edge of the low weight part that is located away from the fold line is longer in the front-rear direction in which the absorbent article is unfolded. It becomes easy to be raised by the wearer side. The low basis weight does not hinder the bonding between the underwear and the bonding portion, maintains the bonding position of the absorbent article, and can further suppress the uncomfortable feeling during wearing and the excrement leakage.

かかる吸収性物品であって、
前記吸収体よりも肌対向面側に設けられた肌面シートと、
前記肌面シートは、前記低目付部と重なる領域において、前記肌面シートよりも非肌対向面側に設けられた部材と接合されていないことが望ましい。 Such an absorbent article,
A skin sheet provided on the skin-facing surface side of the absorber, and
It is desirable that the skin sheet is not joined to a member provided on the non-skin facing surface side of the skin sheet in a region overlapping with the low basis weight portion.

このような吸収性物品によれば、低目付部において肌面シートが肌面シートよりも非肌対向面側に設けられた部材と接合されていないため、弾性部材によって低目付部が縮むように変形する際に、肌面シートが着用者側に膨らむように変形し易くなる。肌面シートが着用者側に***するように変形することにより、下着の引き上げ時に下着の伸長に伴って肌面シートが伸長し、接合部に生じするせん断力を抑制できる。 According to such an absorbent article, since the skin sheet is not joined to the member provided on the non-skin facing surface side of the skin sheet in the low basis weight portion, the low basis weight portion is deformed so as to be contracted by the elastic member. When doing, it becomes easy to change so that a skin sheet may swell to a wearer side. By deforming the skin sheet so that it rises toward the wearer, the skin sheet stretches with the extension of the undergarment when the undergarment is pulled up, and the shearing force generated at the joint can be suppressed.

かかる吸収性物品であって、
前記吸収体よりも非肌対向面側に設けられた非肌面シートと、を有し、
前記肌面シートは、前記低目付部と重なる領域において、前記吸収体と接合されてなく、
前記非肌面シートは、前記低目付部と重なる領域において、前記吸収体と接合されていることが望ましい。 Such an absorbent article,
A non-skin surface sheet provided on the non-skin facing surface side of the absorber,
The skin sheet is not joined to the absorber in a region overlapping with the low basis weight,
It is desirable that the non-skin surface sheet is bonded to the absorber in a region overlapping with the low basis weight.

このような吸収性物品によれば、肌面シートと吸収体が接合されておらず、かつ非肌面シートと吸収体とが接合されているため、吸収体の非肌対向面側よりも吸収体の肌対向面側の剛性が低くなる。そのため、弾性部材によって低目付部が縮むように変形する際に低目付部が肌対向面側に***し易くなる。前後方向に縮んだ状態の低目付部が下着と接合部の接合を阻害せず、吸収性物品の接合位置を維持して、着用時の違和感や***物の漏れを更に抑制することができる。 According to such an absorbent article, since the skin sheet and the absorbent body are not joined and the non-skin face sheet and the absorbent body are joined, the absorbent body absorbs more than the non-skin facing surface side of the absorbent body. The rigidity on the skin facing surface side of the body is lowered. For this reason, when the elastic member is deformed so that the low-weight area is contracted, the low-weight area is likely to rise to the skin facing surface side. The low basis weight portion in the contracted state in the front-rear direction does not hinder the bonding between the underwear and the bonding portion, maintains the bonding position of the absorbent article, and can further suppress discomfort during wearing and excrement leakage.

かかる吸収性物品であって、
前記低目付部は、前記接合部に重ならない領域に配置されることが望ましい。 Such an absorbent article,
It is desirable that the low basis weight is disposed in a region that does not overlap the joint.

このような吸収性物品によれば、低目付部が縮んだ際に、接合部同士がくっつくことを抑制し、接合部を介して吸収性物品と下着との接合状態を維持できる。装着時に吸収性物品が意図せずに折れ曲がったり、位置がずれたりすることを抑制し、着用時の違和感や***物の漏れを更に抑制することができる。 According to such an absorbent article, it is possible to prevent the bonded portions from sticking to each other when the low weight per unit area shrinks, and to maintain the bonded state between the absorbent article and the undergarment via the bonded portion. It is possible to prevent the absorbent article from being unintentionally bent or displaced from being attached at the time of wearing, and to further suppress discomfort and leakage of excrement during wearing.

かかる吸収性物品であって、
前記第２接合部の後端縁は、前記弾性部材によって前後方向に収縮する収縮領域よりも後方に配置されることが望ましい。 Such an absorbent article,
It is preferable that the rear end edge of the second joint portion is disposed behind a contraction region contracted in the front-rear direction by the elastic member.

このような吸収性物品によれば、収縮領域よりも後方に位置する第２接合部は、展開状態において弾性部材の収縮によって縮み難く、下着に対する接合状態を維持し易い。また、下着が引き上げられた際に、下着の変形に伴って収縮領域が伸長し、収縮領域よりも後方に位置する第２接合部と下着との接合状態を維持し易い。よって、吸収性物品の接合位置を維持して、着用時の違和感や***物の漏れを更に抑制することができる。 According to such an absorbent article, the 2nd junction part located back rather than a contraction field cannot be shrunk easily by contraction of an elastic member in a deployment state, and it is easy to maintain the joined state to underwear. In addition, when the underwear is pulled up, the contraction region expands along with the deformation of the underwear, and it is easy to maintain the joint state between the second joint portion and the underwear located behind the contraction region. Therefore, it is possible to maintain the bonding position of the absorbent article and further suppress the uncomfortable feeling at the time of wearing and the leakage of excrement.

かかる吸収性物品であって、
前記後側域において前記幅方向の外側に膨らむヒップフラップを有し、
前記接合部は、前記ヒップフラップに設けられた第３接合部を有し、

A hip flap that bulges outward in the width direction in the rear side region;
The joint has a third joint provided on the hip flap,
It is desirable that the third joint is disposed behind a contraction region that contracts in the front-rear direction by the elastic member.

このような吸収性物品によれば、収縮領域よりも後方に位置する第３接合部は、展開状態において弾性部材の収縮によって縮み難く、下着に対する接合状態を維持し易い。また、下着が引き上げられた際に、下着の変形に伴って収縮領域が伸長し、収縮領域よりも後方に位置する第３接合部と下着との接合状態を維持し易い。ヒップフラップの折り返しや皺の発生を抑制し、着用時の違和感や***物の漏れを更に抑制することができる。 According to such an absorbent article, the third joint located behind the contracted region is not easily contracted by the contraction of the elastic member in the deployed state, and it is easy to maintain the joint state with the undergarment. In addition, when the underwear is pulled up, the contraction region expands along with the deformation of the underwear, and it is easy to maintain the joint state between the third joint located behind the contraction region and the underwear. It is possible to suppress hip flap folding and wrinkle generation, and to further suppress discomfort during wearing and leakage of excrement.

かかる吸収性物品であって、
前記後側域において前記幅方向の外側に膨らむヒップフラップと、
前記ヒップフラップに隣接し、かつ前記中央域において前記幅方向の外側に膨らむウイングと、を有し、
前記低目付部は、前記ヒップフラップの外縁及び前記ウイングの外縁が幅方向の内側に括れた括れ部、又は前記括れ部から前記幅方向の外側に延びる領域に設けられていることが望ましい。 Such an absorbent article,
A hip flap that swells outward in the width direction in the rear side region;
A wing that is adjacent to the hip flap and swells outward in the width direction in the central region;
It is desirable that the low weight portion is provided in a constricted portion in which an outer edge of the hip flap and an outer edge of the wing are constricted on the inner side in the width direction, or an area extending from the constricted portion to the outer side in the width direction.

中央域は、着用者の脚によって挟まれ、幅方向の外側から幅方向の内側に向かう力等がかかり変形し易い。低目付部が括れ部又は括れ部から幅方向の外側に延びる領域に設けられているため、低目付部によって中央域の変形がヒップフラップに伝播することを抑制できる。よって、ヒップフラップのよれや皺を抑制し、着用時の違和感や***物の漏れを抑制することができる。 The central region is sandwiched between the legs of the wearer, and is easily deformed by applying a force or the like from the outer side in the width direction toward the inner side in the width direction. Since the low weight portion is provided in the constricted portion or the region extending outward in the width direction from the constricted portion, it is possible to suppress the deformation of the central region from being propagated to the hip flap by the low weight portion. Accordingly, it is possible to suppress hip flap flaps and wrinkles, and to suppress a sense of incongruity and leakage of excrement when worn.

かかる吸収性物品であって、
前記後側域において前記幅方向の外側に膨らむヒップフラップを有し、
前記ヒップフラップの外縁は、前記幅方向の内側に凹む凹部を有し、

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１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。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、目付及び密度を測定する部分の厚み及び面積を測定する。次いで、目付及び密度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表面シート及び裏面シート等、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、目付及び密度を測定する部分の面積とに基づいて目付を算出する。 When the absorbent article 1 is enclosed in a package or the like, a sample that is removed from the package and left in that state in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH is used. 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 and density are measured are measured. Subsequently, the part which measures a fabric weight and a density is cut out from an absorbent article, and the weight of the cut-out part is measured. Next, parts other than the absorber, such as the top sheet and the back 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 absorbent body and the area of the portion where the basis weight and density are measured.

本明細書における「吸収体の厚さ」の測定は、以下の測定方法によって行われるものとする。吸収性物品１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。測定する際は、吸収性物品が縮んだ状態ではなく、吸収性物品の伸縮性部材を伸張させた状態として測定する。また、吸収体以外の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く。尾崎製作所（株）製のダイアルゲージＰＥＡＣＯＣＫを使用し、測定子には直径１０ｍｍのものを採用し、大きさが３０ｍｍ×３０ｍｍの試片を用意して、当該試片の厚みを測定する。測定器は、試片に対する測定圧が３ｇ／ｃｍ^２となるように調整する。ここで、１０サンプルに対して、それぞれの状態で上述の測定を行い、その平均値を、厚さとした。 The “thickness of the absorber” in this specification is measured by the following measurement method. When the absorbent article 1 is enclosed in a package or the like, a sample that is removed from the package and left in that state in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH is used. When measuring, it is measured not in a state where the absorbent article is contracted but in a state where the elastic member of the absorbent article is extended. Moreover, parts other than an absorber, such as a skin surface sheet other than an absorber, and a non-skin surface sheet, are removed. A dial gauge PEACOCK manufactured by Ozaki Mfg. Co., Ltd. is used, a measuring element having a diameter of 10 mm is used, a specimen having a size of 30 mm × 30 mm is prepared, and the thickness of the specimen is measured. A measuring device adjusts so that the measurement pressure with respect to a test piece may be 3 g / cm < ² >. Here, with respect to 10 samples, the above-described measurement was performed in each state, and the average value was defined as the thickness.

また、本明細書における「長さ」の測定は、以下の測定方法によって行われるものとする。吸収性物品１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。次いで、シンワ測定株式会社製のスプリングメジャー（テープ：ガラス繊維入塩ビ被覆）を用いて、測定対象部位に沿わせるようにして、測定対象部位のこの状態の長さを測定する。ここで、１０サンプルに対して、それぞれの状態で上述の測定を行い、その平均値を、長さとした。 In addition, the “length” in this specification is measured by the following measurement method. When the absorbent article 1 is enclosed in a package or the like, a sample that is removed from the package and left in that state in an atmosphere of 20 ° C. ± 2 ° C. and a relative humidity of 60% ± 5% RH is used. Next, using a spring measure (tape: glass fiber-containing polyvinyl chloride coating) manufactured by Shinwa Measurement Co., Ltd., the length of this state of the measurement target part is measured so as to be along the measurement target part. Here, with respect to 10 samples, the above-described measurement was performed in each state, and the average value was defined as the length.

（２）吸収体の詳細構成
吸収体３０は、低目付部４１を有する。低目付部４１の吸収材料の目付は、中央域の前後方向の中心部における吸収材料の目付よりも低い。「低目付部」は、中央域の前後方向の中心に位置する吸収コア３１よりも低い目付を有する吸収コア３１からなる領域、又は吸収コア３１を有していない領域を意味する。このように、「低目付部」は、吸収コア３１の目付が零である領域を含む概念である。「低目付部４１」が吸収コア３１を有していない領域である場合でも、コアラップ３２は、低目付部４１を跨いで吸収コア３１全体を包んでいてよい。この場合、吸収コア３１が複数の領域に分断されていたとしても、吸収体３０は、コアラップ３２によって一体的に形成される。 (2) Detailed Configuration of Absorber The absorber 30 has a low basis weight 41. The basis weight of the absorbent material in the low basis weight portion 41 is lower than the basis weight of the absorbent material in the center portion in the front-rear direction of the central area. The “low weight portion” means a region composed of the absorbent core 31 having a lower weight than the absorbent core 31 located at the center in the front-rear direction of the central region, or a region not having the absorbent core 31. As described above, the “low weight portion” is a concept including a region where the weight of the absorbent core 31 is zero. Even when the “low weight portion 41” is a region that does not have the absorbent core 31, the core wrap 32 may wrap the entire absorbent core 31 across the low weight portion 41. In this case, even if the absorbent core 31 is divided into a plurality of regions, the absorbent body 30 is integrally formed by the core wrap 32.

低目付部４１は、吸収体３０の剛性が変化する境目となる。したがって、低目付部４１は、吸収体３０が変形し易い領域に相当する。低目付部４１は、幅方向Ｗに延びており、吸収性物品１が厚み方向Ｔに曲がることができるように構成されている。低目付部４１は、幅方向Ｗにおいて、吸収体３０の一端から他端まで延びている。 The low basis weight 41 is a boundary where the rigidity of the absorber 30 changes. Therefore, the low basis weight 41 corresponds to a region where the absorber 30 is easily deformed. The low basis weight 41 extends in the width direction W and is configured so that the absorbent article 1 can be bent in the thickness direction T. The low basis weight 41 extends from one end of the absorber 30 to the other end in the width direction W.

本実施形態では、低目付部４１は、低目付部４１の幅方向Ｗの中央が後方に突出した曲線形状である。より詳細には、低目付部４１の幅方向Ｗの中心は、低目付部４１の外側縁よりも後方に位置する。低目付部４１の前後方向Ｌにおける長さは、一定であってもよいし、一定でなくてもよい。本実施の形態の低目付部４１は、幅方向において前後方向の位置が変化しており、低目付部４１の前後方向の中心４１ＣＬを繋いだ線も、幅方向において前後方向の位置が変化し、幅方向Ｗの中央が後方に突出した曲線形状である。低目付部４１の前端縁４１Ｆは、低目付部全体の前端縁であり、低目付部４１の外側縁４１Ｅにおける低目付部の前端縁である。低目付部４１の後端縁４１Ｒは、低目付部全体の後端縁であり、低目付部４１の幅方向Ｗの中心における低目付部４１の後端縁である。 In the present embodiment, the low weight portion 41 has a curved shape in which the center in the width direction W of the low weight portion 41 protrudes rearward. More specifically, the center of the low weight portion 41 in the width direction W is located behind the outer edge of the low weight portion 41. The length in the front-rear direction L of the low basis weight 41 may be constant or may not be constant. The position of the low weight portion 41 of the present embodiment changes in the front-rear direction in the width direction, and the position connecting the center 41CL in the front-rear direction of the low weight portion 41 also changes the position in the front-rear direction in the width direction. The curved shape is such that the center in the width direction W protrudes backward. The front edge 41F of the low weight part 41 is a front edge of the whole low weight part, and is a front edge of the low weight part in the outer edge 41E of the low weight part 41. The rear edge 41R of the low weight portion 41 is the rear edge of the entire low weight portion, and is the rear edge of the low weight portion 41 at the center of the low weight portion 41 in the width direction W.

低目付部４１は、前後方向Ｌにおける中央域Ｓ１（ウイング３）の中心よりも後側かつ吸収体３０の後側縁よりも前側に設けられていている。低目付部４１の少なくとも一部は、中央域Ｓ１と後側域Ｓ３との境界に設けられている。低目付部４１は、中央域Ｓ１と後側域Ｓ３との境界の少なくとも一部に設けられていればよく、境界の全域に設けられていなくてよい。低目付部４１の少なくとも一部は、ヒップフラップ４の外縁及びウイングの外縁が幅方向の内側に括れた括れ部５であるウイング３の後端縁（ヒップフラップ４の前端縁）又は括れ部５から幅方向の外側に延びる領域に設けられている。中央域Ｓ１は、着用者の脚によって挟まれ、幅方向Ｗの外側から幅方向の内側に向かう力等がかかり変形し易い。括れ部５又は括れ部５から幅方向の外側に延びる領域に低目付部４１が設けられているため、低目付部４１によって中央域Ｓ１の変形を吸収し、当該変形がヒップフラップ４に伝播することを抑制できる。よって、ヒップフラップ４のよれや皺の発生を抑制し、着用時の違和感や***物の漏れを抑制することができる。 The low basis weight 41 is provided on the rear side of the center of the central region S1 (wing 3) in the front-rear direction L and on the front side of the rear edge of the absorber 30. At least a part of the low basis weight 41 is provided at the boundary between the central area S1 and the rear side area S3. The low basis weight 41 may be provided at least at a part of the boundary between the central region S1 and the rear region S3, and may not be provided over the entire boundary. At least a part of the low weight portion 41 is a rear end edge of the wing 3 (a front end edge of the hip flap 4) or a constricted portion 5 which is a constricted portion 5 in which the outer edge of the hip flap 4 and the outer edge of the wing are constricted inward in the width direction. Is provided in a region extending outward in the width direction. The central area S1 is sandwiched between the legs of the wearer and is easily deformed by applying a force or the like from the outer side in the width direction W toward the inner side in the width direction. Since the low weight portion 41 is provided in the narrow portion 5 or the region extending outward in the width direction from the narrow portion 5, the low weight portion 41 absorbs the deformation of the central region S 1, and the deformation propagates to the hip flap 4. This can be suppressed. Therefore, generation | occurrence | production of the hip flap 4 and a wrinkle can be suppressed, and the uncomfortable feeling at the time of wear and the leakage of excrement can be suppressed.

低目付部４１の後端縁４１Ｒよりも後方の領域には、ヒップフラップ４の複数の凹部４Ｃのうち、少なくとも一部の凹部４Ｃが配置されている。低目付部４１の後端縁４１Ｒよりも後方の領域に凹部４Ｃが配置されるため、低目付部４１の変形を凹部４Ｃによって分断し、当該変形が凹部４Ｃよりも後方に伝播することを抑制し、ヒップフラップ４全体に折れや皺が発生することを抑制できる。よって、ヒップフラップ４のよれや皺の発生を抑制し、着用時の違和感や***物の漏れを抑制することができる。 In the region behind the rear edge 41R of the low basis weight portion 41, at least some of the recesses 4C among the plurality of recesses 4C of the hip flap 4 are arranged. Since the recess 4C is arranged in the region behind the rear end edge 41R of the low basis weight 41, the deformation of the low basis weight 41 is divided by the recess 4C, and the deformation is prevented from propagating rearward than the recess 4C. And it can suppress that a fold and a wrinkle generate | occur | produce in the hip-flap 4 whole. Therefore, generation | occurrence | production of the hip flap 4 and a wrinkle can be suppressed, and the uncomfortable feeling at the time of wear and the leakage of excrement can be suppressed.

（３）吸収性物品の折り畳み
吸収性物品１は、使用前には折り線ＦＬ１を基点に折り畳まれている。折り線ＦＬ１は、吸収性物品１の肌対向面同士が対向するように折り畳むための線であり、当該折り畳まれた状態で形成される。折り線ＦＬ１は、着用者に対して谷折りとなる折り癖を形成する。 (3) Folding of absorbent article The absorbent article 1 is folded around the fold line FL1 before use. The fold line FL1 is a line for folding so that the skin facing surfaces of the absorbent article 1 face each other, and is formed in the folded state. The fold line FL1 forms a crease that is a valley fold with respect to the wearer.

図６は、折り線を基点に折り畳まれた吸収性物品１を展開した展開状態の吸収性物品１の模式的斜視図である。図６に示す吸収性物品は、防漏カフを構成する弾性部材９１の収縮によって、低目付部４１及び低目付部４１と重なる領域が着用者側に***している。図７は、図５に示す低目付部４１の模式的拡大図である。図７（ａ）は、吸収性物品が展開し、かつ弾性部材９１が伸長した伸長状態であり、図７（ｂ）は、吸収性物品が展開し、かつ弾性部材９１が収縮した収縮状態である。 FIG. 6 is a schematic perspective view of the absorbent article 1 in an unfolded state in which the absorbent article 1 folded from the fold line is developed. In the absorbent article shown in FIG. 6, due to the contraction of the elastic member 91 constituting the leak-proof cuff, the low weight portion 41 and the region overlapping the low weight portion 41 are raised on the wearer side. FIG. 7 is a schematic enlarged view of the low basis weight 41 shown in FIG. FIG. 7A is an expanded state in which the absorbent article is expanded and the elastic member 91 is expanded. FIG. 7B is a contracted state in which the absorbent article is expanded and the elastic member 91 is contracted. is there.

折り線ＦＬ１は、吸収性物品が展開された展開状態において弾性部材９１の収縮によって低目付部４１が着用者側に***するように設けられている。展開状態において低目付部４１が着用者側に***するように低目付部４１に折り線が設けられているため、第１接合部６１及び第２接合部６２等の接合部６０を下着に接合する際に、低目付部４１が下着Ｓと接合部６０の間に配置され難い。よって、低目付部４１が下着Ｓと接合部６０の接合を阻害せず、接合部６０が意図しない位置に接合したり、接合部６０が折れ曲がったりする不具合を抑制し、接合部６０による接合状態を維持し易い。よって、吸収性物品１の接合位置を維持して、着用時の違和感や***物の漏れを抑制することができる。 The fold line FL1 is provided such that the low basis weight portion 41 is raised on the wearer side by contraction of the elastic member 91 in the expanded state where the absorbent article is expanded. Since the crease line is provided in the low weight portion 41 so that the low weight portion 41 protrudes toward the wearer in the unfolded state, the joint portions 60 such as the first joint portion 61 and the second joint portion 62 are joined to the underwear. When doing so, it is difficult to arrange the low weight per unit area 41 between the undergarment S and the joint 60. Therefore, the low fabric weight part 41 does not inhibit the joining of the undergarment S and the joint part 60, the joint part 60 is joined at an unintended position, or the joint part 60 is bent and the joint state by the joint part 60 is suppressed. Easy to maintain. Therefore, the joining position of the absorbent article 1 can be maintained, and the uncomfortable feeling at the time of wearing and excrement leakage can be suppressed.

折り線ＦＬ１は、幅方向Ｗに延びている。折り線ＦＬ１は、低目付部と、低目付部に隣接する吸収コアと、を跨いで設けられている。折り線ＦＬ１は、低目付部４１の前後方向の中心４１ＣＬと前後方向において離間している。折り線ＦＬ１の少なくとも一部は、低目付部４１の前後方向の中心４１ＣＬと一致しない位置に設けられる。折り線ＦＬ１は、少なくとも一部において低目付部４１の前後方向の中心４１ＣＬと離間して設けられていればよく、部分的に前後方向の中心４１ＣＬと重なるように設けられていてもよい。低目付部４１内には、折り線ＦＬ１と、前後方向Ｌにおいて折り線に隣接した隣接領域と、が形成されている。隣接領域は、低目付部４１よりも前側に位置する吸収コア３１と折り線ＦＬ１との間の前側隣接領域４１１と、低目付部４１よりも後側に位置する吸収コア３１と折り線ＦＬ１との間の後側隣接領域４１２と、が設けられる。 The fold line FL1 extends in the width direction W. The fold line FL1 is provided across the low weight portion and the absorbent core adjacent to the low weight portion. The fold line FL1 is separated from the center 41CL in the front-rear direction of the low weight portion 41 in the front-rear direction. At least a part of the folding line FL1 is provided at a position that does not coincide with the center 41CL in the front-rear direction of the low weight portion 41. The fold line FL1 only needs to be provided at least partially apart from the center 41CL in the front-rear direction of the low weight portion 41, and may be provided so as to partially overlap the center 41CL in the front-rear direction. In the low basis weight 41, a fold line FL1 and an adjacent region adjacent to the fold line in the front-rear direction L are formed. The adjacent region includes a front adjacent region 411 between the absorbent core 31 located on the front side of the low weight part 41 and the fold line FL1, and an absorbent core 31 and a fold line FL1 located on the rear side of the low weight part 41. And a rear adjacent region 412 between.

折り線ＦＬ１が着用者に対して谷折りであるため、折り線ＦＬ１に隣接する隣接領域は、図６及び図７（ｂ）に示す状態において折り線ＦＬ１を基点にして着用者側に***する。折り線ＦＬ１の少なくとも一部は、低目付部４１の前後方向の中心４１ＣＬと一致せずに、低目付部４１の前後方向の中心に対して前後方向にずれている。折り線ＦＬ１が低目付部の前後方向の中心に対してずれた領域では、隣接領域のうち一方（本実施の形態における後側隣接領域４１２）の前後方向Ｌの長さが、他方（本実施の形態における前側隣接領域４１１）の前後方向Ｌの長さよりも長い。一方の隣接領域は、他方の隣接領域よりも吸収性物品の展開状態で***する前後方向の長さが長くなり、着用者側により***し易くなる。 Since the fold line FL1 is a valley fold with respect to the wearer, the adjacent region adjacent to the fold line FL1 is raised on the wearer side with the fold line FL1 as a base point in the state shown in FIGS. 6 and 7B. . At least a part of the folding line FL1 does not coincide with the center 41CL in the front-rear direction of the low basis weight 41, but is shifted in the front-rear direction with respect to the center in the front-rear direction of the low basis weight 41. In the region where the fold line FL1 is shifted from the center in the front-rear direction of the low weight portion, the length in the front-rear direction L of one of the adjacent regions (the rear adjacent region 412 in the present embodiment) is the other (this embodiment) The length in the front-rear direction L of the front side adjacent region 411) is longer. One adjacent region has a longer length in the front-rear direction in which the absorbent article is raised in the deployed state than the other adjacent region, and is more likely to be raised on the wearer side.

（４）吸収性物品の装着態様
次いで、このように構成された吸収性物品の下着Ｓへの装着態様について説明する。着用者は、吸収性物品を下着に装着する際に、まず折り畳まれた折り畳み状態の吸収性物品１を展開する。図６に示すように展開状態において、低目付部４１は、弾性部材９１の収縮によって前後方向Ｌに縮んだ状態となる。次いで、着用者は、展開状態の吸収性物品の接合部を下着に接合する。このとき、下着Ｓは、身体から離された状態であり、具体的には、着用者の股下の下方に配置されている。図８は、装着状態の吸収性物品の、図１のＣ−Ｃ線に沿った模式的断面図である。図８(a)は、展開状態の吸収性物品１を下着に接合し、下着を引き上げる前の状態である。引き上げ前の状態において、吸収性物品１は、第１接合部６１及び第２接合部６２を介して下着に接合され、第１接合部６１と第２接合部６２の間の低目付部４１が前後方向Ｌに収縮している。次いで、着用者は、図８（ａ）に示す吸収性物品を引き上げ、着用者の腰周りに下着Ｓ及び吸収性物品１を配置する。図８（ｂ）は、下着を引き上げ後の状態である。 (4) Mounting Mode of Absorbent Article Next, a mounting mode of the absorbent article configured as described above to the undergarment S will be described. When the wearer attaches the absorbent article to the underwear, the wearer first unfolds the absorbent article 1 in a folded state. As shown in FIG. 6, in the unfolded state, the low basis weight portion 41 is in a state of being contracted in the front-rear direction L due to contraction of the elastic member 91. Next, the wearer joins the joint portion of the developed absorbent article to the underwear. At this time, the underwear S is in a state of being separated from the body, and is specifically arranged below the wearer's crotch. FIG. 8 is a schematic cross-sectional view of the absorbent article in a worn state along the line CC in FIG. FIG. 8 (a) shows a state before the absorbent article 1 in an unfolded state is joined to the underwear and the underwear is pulled up. In the state before pulling up, the absorbent article 1 is joined to the undergarment via the first joint portion 61 and the second joint portion 62, and the low basis weight 41 between the first joint portion 61 and the second joint portion 62 is formed. Shrink in the front-rear direction L. Next, the wearer pulls up the absorbent article shown in FIG. 8A and arranges the underwear S and the absorbent article 1 around the waist of the wearer. FIG. 8B shows a state after the underwear is pulled up.

着用者の腰周りに下着Ｓ及び吸収性物品１が配置される際に、下着Ｓは、着用者の身体に馴染むように伸長する。このとき、下着Ｓの伸長に伴って低目付部４１の縮んだ領域が延び、下着の変形に追従して吸収性物品１が変形する。装着後の状態における第１接合部６１と第２接合部６２との前後方向Ｌの距離は、装着前の状態における第１接合部６１と第２接合部６２との距離よりも長い。第１接合部６１及び第２接合部６２は、装着時に下着から離れ難く、下着を引き上げる前に固定された位置を維持し易い。装着時に吸収性物品１が意図せずに折れ曲がったり、位置がずれたりすることを抑制し、着用時の違和感や***物の漏れを抑制することができる。 When the undergarment S and the absorbent article 1 are disposed around the waist of the wearer, the undergarment S extends so as to become familiar with the wearer's body. At this time, as the undergarment S expands, the region where the low weight per unit area 41 contracts extends, and the absorbent article 1 deforms following the deformation of the undergarment. The distance in the front-rear direction L between the first joint 61 and the second joint 62 in the state after mounting is longer than the distance between the first joint 61 and the second joint 62 in the state before mounting. The first joint portion 61 and the second joint portion 62 are unlikely to be separated from the underwear at the time of wearing, and it is easy to maintain a fixed position before pulling up the underwear. It is possible to prevent the absorbent article 1 from being unintentionally bent or displaced from being attached at the time of wearing, and to suppress a sense of incongruity or leakage of excrement during wearing.

（５）防漏カフ
吸収性物品１は、一対の防漏カフを有する。防漏カフは、着用者側に立ち上がり可能な起立性のギャザーである。防漏カフは、サイドシート１２と、弾性部材９１と、によって構成されている。サイドシート１２の内側縁１２Ｅは、前後方向Ｌに沿って幅方向Ｗの外側に折り返されている。当該折り返されたサイドシート１２間に、前後方向Ｌに伸縮する弾性部材９１が配置されている。サイドシート１２の内側縁１２Ｅは、表面シート１１に接合されていない。サイドシート１２の内側縁１２Ｅ及び弾性部材９１は、起立性の防漏カフを構成する。吸収性物品は、弾性部材９１によって前後方向に収縮する収縮領域を有する。収縮領域とは、弾性部材９１が伸長状態で配置された領域であり、弾性部材によって前後方向に収縮する力がかかる領域である。収縮領域は、弾性部材が非伸長状態で配置された領域を除く概念である。図１における弾性部材９１は、収縮領域のみを示しており、非伸長状態で弾性部材が配置された領域を示していない。そのため、図１における弾性部材９１の範囲は、収縮領域の範囲と一致する。収縮領域は、前後方向Ｌにおいて中央域Ｓ１を跨って配置されている。 (5) Leak-proof cuff The absorbent article 1 has a pair of leak-proof cuffs. The leak-proof cuff is an upright gather that can stand on the wearer side. The leak-proof cuff is configured by the side seat 12 and the elastic member 91. The inner edge 12 E of the side seat 12 is folded back along the front-rear direction L in the width direction W. An elastic member 91 that expands and contracts in the front-rear direction L is disposed between the folded side sheets 12. The inner edge 12 E of the side sheet 12 is not joined to the top sheet 11. The inner edge 12E and the elastic member 91 of the side seat 12 constitute an upright leakproof cuff. The absorbent article has a contraction region that contracts in the front-rear direction by the elastic member 91. A contraction area | region is an area | region where the elastic member 91 is arrange | positioned in the expansion | extension state, and is an area | region where the force contracted in the front-back direction by an elastic member is applied. A contraction area | region is a concept except the area | region where the elastic member is arrange | positioned in the non-expanded state. The elastic member 91 in FIG. 1 shows only the contraction region, and does not show the region where the elastic member is arranged in a non-expanded state. Therefore, the range of the elastic member 91 in FIG. 1 matches the range of the contraction region. The contraction region is arranged across the central region S1 in the front-rear direction L.

防漏カフを構成する弾性部材９１は、前後方向Ｌにおいて低目付部４１又は低目付部４１から幅方向の外側に延びる領域を跨いで配置される。より詳細には、弾性部材９１の前端縁９１Ｆは、低目付部４１の前端縁４１Ｆよりも前方に位置し、弾性部材９１の後端縁９１Ｒは、低目付部４１の後端縁４１Ｒよりも後方に位置する。低目付部４１から幅方向の外側に延びる領域とは、低目付部４１の前端縁４１Ｆと低目付部４１の後端縁４１Ｒとの間の領域から幅方向に延びる領域である。低目付部４１は、中央域の前後方向の中心よりも目付が低く、変形し易い。また、低目付部４１は、隣接する中央域Ｓ１（又は後側域Ｓ３）の吸収コア３１と目付が異なり、剛性が変化する境界である。よって、低目付部４１と隣接する吸収コアとの境界を基点に変形し易い。加えて、弾性部材９１が低目付部４１又は低目付部４１から幅方向の外側に延びる領域を跨いでいる。このような構成により、弾性部材９１の収縮に伴い、低目付部４１の前後方向の長さが短くなるように変形し、低目付部４１が前後方向に縮んだ状態となる。よって、装着時の下着Ｓの伸長に伴って低目付部４１の縮んだ領域が延び、下着の変形に追従して吸収性物品１が変形できる。第１接合部６１及び第２接合部６２は、装着時に下着から離れ難く、下着を引き上げる前に固定された位置を維持し易い。装着時に吸収性物品１が意図せずに折れ曲がったり、位置がずれたりすることを抑制し、着用時の違和感や***物の漏れを抑制することができる。 The elastic member 91 constituting the leak-proof cuff is disposed across the low weight part 41 or the region extending from the low weight part 41 to the outside in the width direction in the front-rear direction L. More specifically, the front end edge 91F of the elastic member 91 is positioned in front of the front end edge 41F of the low weight portion 41, and the rear end edge 91R of the elastic member 91 is more than the rear end edge 41R of the low weight portion 41. Located behind. The region extending outward in the width direction from the low weight portion 41 is a region extending in the width direction from a region between the front end edge 41F of the low weight portion 41 and the rear end edge 41R of the low weight portion 41. The low basis weight 41 has a lower basis weight than the center of the central area in the front-rear direction and is easily deformed. The low basis weight 41 is a boundary where the basis weight is different from the absorption core 31 of the adjacent central area S1 (or the rear side area S3) and the rigidity changes. Therefore, it is easy to deform | transform using the boundary of the low fabric weight part 41 and the adjacent absorption core as a base point. In addition, the elastic member 91 straddles the low weight portion 41 or the region extending from the low weight portion 41 to the outside in the width direction. With such a configuration, as the elastic member 91 contracts, the low basis weight 41 is deformed so that the length in the front-rear direction is shortened, and the low basis weight 41 is contracted in the front-rear direction. Therefore, the area | region where the low weight part 41 contracted extended with the expansion | extension of the underwear S at the time of mounting | wearing, and the absorbent article 1 can deform | transform following the deformation | transformation of underwear. The first joint portion 61 and the second joint portion 62 are unlikely to be separated from the underwear at the time of wearing, and it is easy to maintain a fixed position before pulling up the underwear. It is possible to prevent the absorbent article 1 from being unintentionally bent or displaced from being attached at the time of wearing, and to suppress a sense of incongruity or leakage of excrement during wearing.

（６）肌面シートと吸収体との間の非接合領域及び非肌面シートと吸収体との間の接合領域
肌面シート１０は、低目付部４１と重なる領域において、肌面シート１０よりも非肌対向面側に設けられた部材と接合されていない。肌面シート１０よりも非肌対向面側に設けられた部材とは、吸収体及びセカンドシートを例示できる。より具体的には、図１に示す非接合領域４６において、肌面シート１０と吸収体３０を構成するコアラップ３２とは、接合されていない。非接合領域４６は、図１において、破線で囲まれた領域によって示されている。非接合領域４６は、少なくとも、幅方向Ｗにおける低目付部４１の一端から他端まで延びていてよい。この代わりに、非接合領域４６は、幅方向Ｗにおいて低目付部４１の両端部まで延びていなくてもよい。低目付部４１において肌面シートが肌面シートよりも非肌対向面側に設けられた部材と接合されていないため、弾性部材によって低目付部４１が縮むように変形する際に、肌面シートが着用者側に膨らむように変形し易くなる。 (6) Non-joint region between skin sheet and absorbent body and joint region between non-skin face sheet and absorbent body Skin sheet 10 is in a region overlapping with low basis weight portion 41 than skin sheet 10. Is not joined to a member provided on the non-skin facing surface side. Examples of the member provided on the non-skin facing surface side with respect to the skin sheet 10 include an absorber and a second sheet. More specifically, in the non-joining region 46 shown in FIG. 1, the skin sheet 10 and the core wrap 32 constituting the absorbent body 30 are not joined. The non-bonding region 46 is indicated by a region surrounded by a broken line in FIG. The non-joining region 46 may extend at least from one end to the other end of the low weight portion 41 in the width direction W. Instead, the non-joining region 46 may not extend to both ends of the low weight portion 41 in the width direction W. Since the skin sheet is not joined to the member provided on the non-skin facing surface side than the skin sheet in the low basis weight 41, the skin sheet is deformed so that the low basis weight 41 is contracted by the elastic member. It becomes easy to deform so as to swell toward the wearer.

非肌面シート２０は、低目付部４１と重なる領域において、非肌面シート２０よりも肌対向面側に設けられた部材と接合されている。より、具体的には、非肌面シート２０と吸収体を構成するコアラップとは、接合されている。肌面シート１０と吸収体３０が接合されておらず、かつ非肌面シート２０と吸収体３０とが接合されているため、吸収性物品の非肌対向面側よりも肌対向面側の剛性が低くなり、弾性部材によって低目付部４１が縮むように変形する際に低目付部４１が肌対向面側に***し易くなる。低目付部４１が下着と接合部の接合を阻害せず、吸収性物品の接合位置を維持して、着用時の違和感や***物の漏れを更に抑制することができる。 The non-skin surface sheet 20 is joined to a member provided on the skin facing surface side of the non-skin surface sheet 20 in a region overlapping with the low basis weight portion 41. More specifically, the non-skin surface sheet 20 and the core wrap constituting the absorber are joined. Since the skin sheet 10 and the absorbent body 30 are not joined and the non-skin face sheet 20 and the absorbent body 30 are joined, the rigidity of the absorbent article on the skin facing surface side rather than the non-skin facing surface side of the absorbent article The lower weight portion 41 is easily raised on the skin facing surface side when the lower weight portion 41 is deformed so as to be contracted by the elastic member. The low basis weight 41 does not hinder the bonding between the undergarment and the bonding portion, maintains the bonding position of the absorbent article, and can further suppress a sense of incongruity and leakage of excrement during wearing.

（７）接合部
第１接合部６１は、第２接合部６２よりも前方、かつ低目付部４１よりも前方に配置されている。第２接合部６２は、前後方向Ｌにおいて第１接合部６１と離間して配置されている。第２接合部６２は、低目付部４１よりも後方に配置されている。第１接合部６１と第２接合部６２とが低目付部４１を挟んで配置されているため、引き上げ前の状態から引き上げ後の状態に変化する際に、下着の伸長に伴って第１接合部６１と第２接合部６２との距離が離れるように引っ張られても、低目付部４１が伸長し、第１接合部６１と第２接合部６２の接合を維持することができる。後側域Ｓ３に位置する第２接合部が下着から離れることを抑制し、装着時に吸収性物品の後端縁が肌対向面側に折れ曲がったり、吸収性物品の後側域の位置が幅方向においてずれてしまったりする不具合を抑制できる。これにより、着用時の違和感や***物の漏れを抑制できる。 (7) Joining portion The first joining portion 61 is disposed in front of the second joining portion 62 and in front of the low weighted portion 41. The second joint portion 62 is disposed away from the first joint portion 61 in the front-rear direction L. The second joint portion 62 is disposed behind the low weight portion 41. Since the 1st junction part 61 and the 2nd junction part 62 are arrange | positioned on both sides of the low fabric weight part 41, when changing from the state before raising to the state after raising, it is 1st joining with extension of underwear. Even if the portion 61 and the second joint portion 62 are pulled away from each other, the low basis weight portion 41 is extended, and the first joint portion 61 and the second joint portion 62 can be kept joined. The second joint portion located in the rear side region S3 is prevented from separating from the underwear, the rear end edge of the absorbent article is bent toward the skin facing surface side when worn, and the position of the rear side region of the absorbent article is the width direction It is possible to suppress problems such as slipping. Thereby, the uncomfortable feeling at the time of wear and the leakage of excrement can be suppressed.

低目付部４１は、接合部６０に重ならない領域に配置される。このような構成によれば、弾性部材９１の収縮によって低目付部４１が縮んだ際に、接合部６０同士がくっつくことを抑制できる。接合部６０が位置しない箇所に接合することを防止し、接合部６０を介して吸収性物品１と下着Ｓとの接合状態を維持できる。装着時に吸収性物品が意図せずに折れ曲がったり、位置がずれたりすることを抑制し、着用時の違和感や***物の漏れを更に抑制することができる。 The low basis weight 41 is disposed in a region that does not overlap the joint 60. According to such a configuration, when the low basis weight portion 41 is contracted by the contraction of the elastic member 91, it is possible to suppress the joint portions 60 from sticking to each other. It can prevent joining to the location where junction part 60 is not located, and can maintain the joined state of absorptive article 1 and underwear S via junction part 60. It is possible to prevent the absorbent article from being unintentionally bent or displaced from being attached at the time of wearing, and to further suppress discomfort and leakage of excrement during wearing.

第３接合部６３と第４接合部６４の間には、低目付部４１から幅方向に延びる領域の少なくとも一部が配置される。そのため、下着の伸長に伴って第３接合部６３と第４接合部６４との距離が離れるように引っ張られても、低目付部４１が伸長し、第３接合部６３と第４接合部６４の接合を維持することができる。吸収性物品の後側域に位置する第３接合部６３が下着から離れることを抑制し、装着時にヒップフラップ４が肌対向面側に折れ曲がったり、ヒップフラップ４の位置が幅方向においてずれてしまったりする不具合を抑制できる。これにより、着用時の違和感や***物の漏れを抑制できる。 Between the third joint portion 63 and the fourth joint portion 64, at least a part of a region extending in the width direction from the low weight portion 41 is disposed. Therefore, even if the third joint portion 63 and the fourth joint portion 64 are pulled away from each other along with the extension of the underwear, the low basis weight portion 41 extends, and the third joint portion 63 and the fourth joint portion 64 are stretched. Can be maintained. The third joint portion 63 located in the rear region of the absorbent article is prevented from separating from the underwear, the hip flap 4 is bent to the skin facing surface side when worn, and the position of the hip flap 4 is shifted in the width direction. It is possible to suppress troubles that occur. Thereby, the uncomfortable feeling at the time of wear and the leakage of excrement can be suppressed.

第２接合部６２の後端縁は、弾性部材９１によって前後方向に収縮する収縮領域よりも後方に配置される。収縮領域よりも後方に位置する第２接合部６２は、展開状態において弾性部材９１の収縮によって縮まり難く、下着に対する接合状態を維持し易い。また、下着が引き上げられた際に、下着の変形に伴って収縮領域が伸長し、収縮領域よりも後方に位置する第２接合部６２と下着との接合状態を維持し易い。よって、吸収性物品の接合位置を維持して、着用時の違和感や***物の漏れを更に抑制することができる。 The rear end edge of the second joint portion 62 is disposed behind the contracted region that contracts in the front-rear direction by the elastic member 91. The second joint portion 62 located behind the contraction region is not easily contracted by the contraction of the elastic member 91 in the deployed state, and it is easy to maintain the joint state with the underwear. In addition, when the underwear is pulled up, the contraction region expands along with the deformation of the underwear, and it is easy to maintain the joint state between the second joint portion 62 located behind the contraction region and the underwear. Therefore, it is possible to maintain the bonding position of the absorbent article and further suppress the uncomfortable feeling at the time of wearing and the leakage of excrement.

第３接合部６３の前端縁６３Ｆ及び第３接合部６３の後端縁６３Ｒは、弾性部材によって前後方向に収縮する収縮領域よりも後方に配置される。収縮領域よりも後方に位置する第３接合部は、展開状態において弾性部材の収縮によって縮まり難く、下着に対する接合状態を維持し易い。また、収縮領域と第３接合部が前後方向に離間しているため、下着の変形に伴って収縮領域が伸長した際に、第３接合部と下着との接合状態を維持し易い。ヒップフラップの折り返しや皺の発生を抑制し、着用時の違和感や***物の漏れを更に抑制することができる。 The front end edge 63F of the third joint portion 63 and the rear end edge 63R of the third joint portion 63 are disposed behind the contraction region contracted in the front-rear direction by the elastic member. The third joint located behind the contraction region is unlikely to shrink due to contraction of the elastic member in the deployed state, and it is easy to maintain the joint state with the undergarment. In addition, since the contraction region and the third joint portion are separated from each other in the front-rear direction, it is easy to maintain the joint state between the third joint portion and the undergarment when the contraction region expands with the deformation of the underwear. It is possible to suppress hip flap folding and wrinkle generation, and to further suppress discomfort during wearing and leakage of excrement.

第４接合部６４は、低目付部４１と離間しており、低目付部４１の前端縁４１Ｆとよりも前方に配置される。第４接合部６４は、装着された状態で下着のクロッチ部に接合する。下着のクロッチ部は、二重布等で構成されており、下着の臀部に当てられる領域よりも剛性が高く伸長し難い。また、下着のクロッチ部は、吸収性物品１の第１接合部６１と第４接合部６４が接合し、厚み方向Ｔにおいて吸収性物品１に挟まれており、下着の臀部に当てられる領域と比較して伸長し難い。すなわち、第４接合部６４が接合する領域は、伸長し難い領域である。これに対して、下着の臀部に当てられる領域は、下着のクロッチ部よりも伸長し易い領域である。第４接合部６４よりも後方に低目付部４１が配置されているため、下着の臀部に当てられる領域の伸長に伴って低目付部４１が前後方向に伸長し易くなり、下着の変形に追従して吸収性物品がより変形し易くなる。 The fourth joint portion 64 is separated from the low weight portion 41 and is disposed further forward than the front end edge 41F of the low weight portion 41. The fourth joint portion 64 is joined to the crotch portion of the underwear in a mounted state. The crotch part of the underwear is composed of a double cloth or the like, and has a higher rigidity than the region applied to the heel part of the underwear and hardly stretches. Further, the crotch portion of the underwear is a region where the first joint portion 61 and the fourth joint portion 64 of the absorbent article 1 are joined and sandwiched between the absorbent articles 1 in the thickness direction T and applied to the heel portion of the underwear. It is hard to extend compared with. That is, the region where the fourth joint portion 64 is joined is a region that is difficult to extend. On the other hand, the area | region applied to the collar part of underwear is an area | region which expand | extends easily rather than the crotch part of underwear. Since the low basis weight 41 is arranged behind the fourth joint portion 64, the low basis weight 41 easily extends in the front-rear direction along with the extension of the area applied to the buttocks of the underwear, and follows the deformation of the underwear. Thus, the absorbent article is more easily deformed.

（８）圧搾部
吸収性物品１は、少なくとも吸収コア３１が厚み方向に圧縮されることによって形成された圧搾部を有する。圧搾部は、前側圧搾部８１と後側圧搾部８２を有する。前側圧搾部８１と後側圧搾部８２は、前後方向において離間している。前側圧搾部８１の少なくとも一部及び後側圧搾部８２の少なくとも一部は、弾性部材９１の収縮領域の前後方向の範囲内に設けられる。前側圧搾部８１は、低目付部４１を前後方向に跨って配置されていない。また、後側圧搾部８２は、低目付部４１内に設けられていない。このような構成によれば、低目付部４１よりも前側の領域は、前側圧搾部によって剛性が高くなり、弾性部材の収縮力に対して変形し難く、フラットな状態で吸収体が維持され易い。同様に、低目付部４１よりも後側の領域は、後側圧搾部によって剛性が高くなり、弾性部材の収縮力に対して変形し難く、フラットな状態で吸収体が維持され易い。吸収体がフラットな状態で維持され易いため、着用者の肌に対して平滑な面で当接し、装着時の違和感の発生を抑制できる。一方、低目付部４１は、前後方向の全域にわたって圧搾部が形成されないため、弾性部材の収縮によって縮むように変形し易く、下着の伸長に伴って伸長するように変形できる。弾性部材の収縮力が高く、低目付部４１の収縮量が大きい構成であっても、吸収体の型崩れを抑制し、良好な使用感を維持できる。吸収性物品の下着に対する追従性能を高めることができる。 (8) Compressed part The absorbent article 1 has a compressed part formed by compressing at least the absorbent core 31 in the thickness direction. The pressing part has a front pressing part 81 and a rear pressing part 82. The front pressing part 81 and the rear pressing part 82 are separated in the front-rear direction. At least a part of the front pressing part 81 and at least a part of the rear pressing part 82 are provided within a range in the front-rear direction of the contraction region of the elastic member 91. The front side compressed portion 81 is not disposed across the low basis weight portion 41 in the front-rear direction. Further, the rear pressing part 82 is not provided in the low basis weight part 41. According to such a configuration, the region on the front side of the low basis weight portion 41 is increased in rigidity by the front side squeezing portion, hardly deforms due to the contraction force of the elastic member, and the absorber is easily maintained in a flat state. . Similarly, the region on the rear side of the low basis weight portion 41 is increased in rigidity by the rear side compressed portion, is not easily deformed by the contraction force of the elastic member, and the absorber is easily maintained in a flat state. Since it is easy to maintain an absorber in a flat state, it contacts with a wearer's skin by a smooth surface, and generation | occurrence | production of the uncomfortable feeling at the time of mounting | wearing can be suppressed. On the other hand, since the pressing part is not formed over the whole area in the front-rear direction, the low basis weight part 41 can be easily deformed so as to be contracted by the contraction of the elastic member, and can be deformed so as to be expanded as the underwear is expanded. Even when the elastic member has a high contraction force and the low basis weight 41 has a large contraction amount, the absorber can be prevented from being deformed and a good feeling of use can be maintained. The follow-up performance with respect to the underwear of an absorbent article can be improved.

（９）変形例
次いで、図９及び１０に基づいて変形例に係る実施形態について説明する。なお、変形例の実施形態の説明において、上述の実施形態と同様の構成については同符号を用いて説明を省略する。図９は、変形例に係る吸収性物品の平面図であり、図１０は、変形例に係る吸収性物品の背面図である。変形例に係る吸収性物品１Ａは、複数の低目付部４１が設けられている。複数の低目付部４１は、前後方向に間隔を空けて配置されている。複数の低目付部４１を有する構成にあっては、折り線ＦＬ１は、少なくとも一部の低目付部に設けられていればよく、変形例に係る吸収性物品１Ａは、最も前側に位置する低目付部４１に折り線ＦＬ１が設けられている。 (9) Modified Example Next, an embodiment according to a modified example will be described based on FIGS. In the description of the embodiment of the modification, the same reference numerals are used for the same configurations as those of the above-described embodiment, and the description thereof is omitted. FIG. 9 is a plan view of an absorbent article according to a modified example, and FIG. 10 is a rear view of the absorbent article according to the modified example. The absorbent article 1 A according to the modification is provided with a plurality of low weight parts 41. The plurality of low weight portions 41 are arranged at intervals in the front-rear direction. In the configuration having a plurality of low basis weights 41, the fold line FL1 only needs to be provided in at least a part of the low basis weights, and the absorbent article 1A according to the modified example has a low front position. A fold line FL 1 is provided in the basis weight 41.
