上記のように、パンツやショーツ等の下着の肌面側に設置して使用する吸収性物品には、粘着部や滑り止め部が設けられたものが様々知られているが、このような吸収性物品は、着用者の股間の肌と下着の間に好適に設置できるとともに、着用者から排泄された尿等を確実に吸収し、尿等の漏れを効果的に防止することが望まれる。本発明は前記事情に鑑みてなされたものであり、その目的は、着用者の股間に好適に装着することができ、尿等の漏れを効果的に防止できる吸収性物品を提供することにある。 As described above, various absorbent articles such as pants and shorts that are installed and used on the skin side of underwear are provided with an adhesive portion and a non-slip portion. Such absorption It is desired that the sex article can be suitably installed between the skin of the wearer's crotch and the underwear, and that the urine or the like excreted from the wearer is surely absorbed and the leakage of the urine or the like is effectively prevented. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an absorbent article that can be suitably worn in the crotch of a wearer and can effectively prevent leakage of urine or the like. ..

前記課題を解決することができた本発明の吸収性物品とは、前後方向と幅方向を有し、トップシートとバックシートとこれらの間に設けられた吸収体を有する吸収性物品であって、トップシートの幅方向の両側に立ち上がりフラップが設けられ、立ち上がりフラップは、前側固定部と後側固定部とこれらの間の中間部を有し、少なくとも中間部に前後方向に延びるフラップ弾性部材が設けられ、前側固定部と後側固定部がトップシートに接合されることにより中間部が起立可能に形成され、トップシートの肌面側には、前側固定部の後側端よりも前側および後側固定部の前側端よりも後側にそれぞれ粘着部が設けられ、バックシートの非肌面側には、前側固定部の後側端よりも後側かつ後側固定部の前側端よりも前側に滑り止め部が設けられているところに特徴を有する。 The absorbent article of the present invention that has been able to solve the above problems is an absorbent article having a front-rear direction and a width direction, and having a top sheet, a back sheet, and an absorber provided between them. , The rising flaps are provided on both sides in the width direction of the top sheet, and the rising flap has an intermediate portion between the front fixing portion and the rear fixing portion, and at least the intermediate portion has a flap elastic member extending in the front-rear direction. An intermediate portion is formed so as to be able to stand up by being provided and the front fixing portion and the rear fixing portion are joined to the top sheet, and the skin surface side of the top sheet is front and rear of the rear end of the front fixing portion. Adhesive portions are provided on the rear side of the front end of the side fixing portion, and on the non-skin surface side of the back sheet, the back side of the front fixing portion and the front side of the front end of the rear fixing portion. It is characterized in that a non-slip portion is provided on the.

本発明の吸収性物品は、トップシートの肌面側に設けられた粘着部によって着用者の股間部の肌に貼り付けることができ、着用者の股間の所望の位置に密着性良く設置することができる。この際、前側固定部の後側端よりも前側および後側固定部の前側端よりも後側に粘着部を設けることによって、立ち上がりフラップの中間部を好適に起立させることができるため、尿等の横漏れを効果的に防止することができる。また、粘着部は排尿部から離れた位置に設けられるため、粘着部が尿等によって濡れにくくなり、粘着力を長く持続させやすくなる。一方、バックシートの非肌面側に設けられた滑り止め部によって、吸収性物品をパンツやショーツ等の下着の所定の位置に設置することができ、吸収性物品が下着からはみ出したりすることを防ぐことができる。また、粘着部ではなく滑り止め部をバックシートの非肌面側に設けることにより、バックシートと下着との間のずれ応力が大きくなったときに、当該ずれ応力を緩和するように互いの接触位置をずらすことができ、吸収性物品や下着に大きな歪みやしわが生じにくくなる。そのため、本発明の吸収性物品によれば、着用者の股間に好適に装着することができ、尿等の漏れを効果的に防止できる。 The absorbent article of the present invention can be attached to the skin of the wearer's crotch portion by the adhesive portion provided on the skin surface side of the top sheet, and is installed at a desired position of the wearer's crotch with good adhesion. Can be done. At this time, by providing the adhesive portion on the front side of the rear end of the front fixing portion and on the rear side of the front end of the rear fixing portion, the intermediate portion of the rising flap can be suitably erected, so that urine or the like can be urinated. Side leakage can be effectively prevented. Further, since the adhesive portion is provided at a position away from the urination portion, the adhesive portion is less likely to get wet by urine or the like, and the adhesive force can be easily maintained for a long time. On the other hand, the non-slip portion provided on the non-skin surface side of the back sheet allows the absorbent article to be installed at a predetermined position of the underwear such as pants and shorts, so that the absorbent article may protrude from the underwear. Can be prevented. In addition, by providing a non-slip portion instead of an adhesive portion on the non-skin surface side of the back sheet, when the displacement stress between the back sheet and the underwear becomes large, they come into contact with each other so as to alleviate the displacement stress. The position can be shifted, and large distortions and wrinkles are less likely to occur in absorbent articles and underwear. Therefore, according to the absorbent article of the present invention, it can be suitably worn in the crotch of the wearer, and leakage of urine or the like can be effectively prevented.

滑り止め部は、前後方向に並んで複数設けられていることが好ましい。このように滑り止め部を設けることにより、吸収性物品を前後方向に湾曲させることが容易になり、吸収性物品の着用者の股間部へのフィット性を高めることができる。 It is preferable that a plurality of non-slip portions are provided side by side in the front-rear direction. By providing the non-slip portion in this way, it becomes easy to bend the absorbent article in the front-rear direction, and the fit of the absorbent article to the wearer's crotch portion can be improved.

粘着部は、吸収体の前側端と重なって設けられるか、前側端よりも前側に設けられ、吸収体の後側端と重なって設けられるか、後側端よりも後側に設けられていることが好ましい。このように粘着部を設けることにより、吸収性物品を安定して着用者の肌に貼り付けることができる。また、吸収体のより広い範囲が尿等の吸収に寄与できるものとなる。 The adhesive portion is provided so as to overlap the front end of the absorber, or be provided on the front side of the front end, overlap with the rear end of the absorber, or be provided on the rear side of the rear end. Is preferable. By providing the adhesive portion in this way, the absorbent article can be stably attached to the wearer's skin. In addition, a wider range of absorbers can contribute to the absorption of urine and the like.

吸収体は高剛性部と低剛性部とを有し、高剛性部と低剛性部はそれぞれ前後方向に延在し、高剛性部と低剛性部が幅方向に交互に並んで配されており、滑り止め部が複数の高剛性部に跨がって設けられているものであってもよい。このように吸収体が形成されていれば、吸収性物品が着用者の両大腿部に挟まれて幅方向の内方に向かう力がかかっても、吸収体に不規則な折り目が形成されにくくなり、幅方向の内方に向かう力を好適に吸収することができる。また滑り止め部が複数の高剛性部に跨がって設けられることにより、吸収性物品に幅方向への剛性が付与され、吸収性物品の幅方向の内方に向かう力が解除されると、吸収性物品がもとの平面状に広がりやすくなる。 The absorber has a high-rigidity portion and a low-rigidity portion, the high-rigidity portion and the low-rigidity portion extend in the front-rear direction, respectively, and the high-rigidity portion and the low-rigidity portion are arranged alternately in the width direction. , The non-slip portion may be provided so as to straddle a plurality of high-rigidity portions. If the absorber is formed in this way, irregular creases are formed in the absorber even if the absorbent article is sandwiched between the wearer's thighs and an inward force is applied in the width direction. It becomes difficult and can preferably absorb the inward force in the width direction. Further, when the non-slip portion is provided across the plurality of high-rigidity portions, the absorbent article is imparted with rigidity in the width direction, and the inward force in the width direction of the absorbent article is released. , The absorbent article tends to spread in its original flat shape.

吸収体は、シート部材の間に吸水性樹脂を有しパルプ繊維を有しないように構成され、シート部材どうしが接合された封止部と、シート部材どうしが接合されない非封止部とを有し、非封止部に吸水性樹脂が配されているものであってもよい。この場合、封止部が低剛性部を形成し、非封止部が高剛性部を形成することができる。 The absorber is configured to have a water-absorbent resin between the sheet members and not to have pulp fibers, and has a sealing portion in which the sheet members are bonded to each other and a non-sealing portion in which the sheet members are not bonded to each other. However, a water-absorbent resin may be arranged in the non-sealing portion. In this case, the sealed portion can form a low-rigidity portion, and the non-sealed portion can form a high-rigidity portion.

滑り止め部は、吸収体よりも幅方向に狭く形成されていることが好ましい。このように滑り止め部を設けることにより、吸収性物品の幅方向の両端部の下着の動きへの滑り性が高まる。そのため、吸収性物品を下着に取り付けた状態で着用者が大腿部を大きく動かしても、吸収性物品に歪みが生じにくくなる。 The non-slip portion is preferably formed narrower in the width direction than the absorber. By providing the non-slip portion in this way, the slipperiness to the movement of the underwear at both ends in the width direction of the absorbent article is enhanced. Therefore, even if the wearer moves the thigh greatly with the absorbent article attached to the underwear, the absorbent article is less likely to be distorted.

吸収性物品は、肌面側を内側にして、幅方向に延びる第１の折り目とそれより後側に位置する第２の折り目で折り返されることにより前後方向に３つ折りされるものであってもよい。この場合、粘着部は、第１の折り目よりも前側および第２の折り目よりも後側にそれぞれ設けられていることが好ましい。このように折り畳まれた吸収性物品は、吸収性物品の折り畳みを展開して着用者の股間に取り付ける際、第１の折り目と第２の折り目の折り癖によって、吸収性物品の第１の折り目よりも前側の部分および第２の折り目よりも後側の部分が着用者の肌に向かって立ち上がりやすくなる。そのため、当該部分に粘着部を設けることにより、粘着部によって吸収性物品を着用者の肌に好適に取り付けやすくなる。 Even if the absorbent article is folded in three in the front-rear direction by being folded back at the first crease extending in the width direction and the second crease located behind it with the skin surface side inside. Good. In this case, it is preferable that the adhesive portion is provided on the front side of the first fold and on the rear side of the second fold, respectively. When the absorbent article folded in this way is unfolded and attached to the wearer's crotch, the first fold of the absorbent article is caused by the fold habit of the first crease and the second fold. The anterior portion and the posterior portion of the second crease are more likely to stand up toward the wearer's skin. Therefore, by providing the adhesive portion in the portion, the adhesive portion makes it easier to suitably attach the absorbent article to the wearer's skin.

滑り止め部は、第１の折り目から前後方向に１０ｍｍ以内の領域に設けられ、第２の折り目から前後方向に１０ｍｍ以内の領域に設けられていることが好ましい。第１の折り目とその近傍および第２の折り目とその近傍では、折り畳まれた吸収性物品を展開した際に、当該部分で吸収性物品が下着と接しやすくなる。従って、第１の折り目またはその近傍および第２の折り目またはその近傍に滑り止め部を設けることにより、吸収性物品をパンツやショーツ等の下着の所定の位置に固定させやすくなる。 It is preferable that the non-slip portion is provided in a region within 10 mm in the front-rear direction from the first crease, and is provided in a region within 10 mm in the front-rear direction from the second fold. At the first fold and its vicinity and at the second fold and its vicinity, when the folded absorbent article is unfolded, the absorbent article easily comes into contact with the underwear at that portion. Therefore, by providing the non-slip portion at or near the first fold and at or near the second crease, it becomes easy to fix the absorbent article at a predetermined position of underwear such as pants and shorts.

本発明の吸収性物品によれば、着用者の股間の所望の位置に密着性良く装着することができ、尿等の漏れを効果的に防止できる。 According to the absorbent article of the present invention, it can be attached to a desired position in the crotch of the wearer with good adhesion, and leakage of urine or the like can be effectively prevented.

In the figure of the present application, the arrow x represents the width direction, the arrow y represents the front-back direction, and the direction perpendicular to the plane formed by the arrows x, y represents the thickness direction z. In FIGS. 1 and 2, the upper side of the drawing corresponds to the front side of the absorbent article, and the lower side of the drawing corresponds to the rear side of the absorbent article.

吸収性物品１は、トップシート２とバックシート３とこれらの間に設けられた吸収体４とを有する。トップシート２は吸収体４の肌面側に配され、バックシート３は吸収体４の非肌面側に配されている。トップシート２を透過した排泄物は、吸収体４により収容される。バックシート３は排泄物が外へ漏れるのを防いでいる。 The absorbent article 1 has a top sheet 2, a back sheet 3, and an absorber 4 provided between them. The top sheet 2 is arranged on the skin surface side of the absorber 4, and the back sheet 3 is arranged on the non-skin surface side of the absorber 4. The excrement that has passed through the top sheet 2 is contained by the absorber 4. The back sheet 3 prevents excrement from leaking to the outside.

吸収性物品１は、前後方向ｙと幅方向ｘを有する。前後方向ｙとは、吸収性物品を着用した際に着用者の股間の前後方向に延びる方向に相当する。幅方向ｘとは、吸収性物品と同一面上にあり前後方向ｙと直交する方向を意味し、吸収性物品を着用した際の着用者の左右方向に相当する。また、吸収性物品を着用者が着用した際に、着用者の肌に向かう側を肌面側とし、その反対側を非肌面側とする。 The absorbent article 1 has a front-rear direction y and a width direction x. The anteroposterior direction y corresponds to a direction extending in the anteroposterior direction of the wearer's crotch when the absorbent article is worn. The width direction x means a direction that is on the same plane as the absorbent article and orthogonal to the front-rear direction y, and corresponds to the left-right direction of the wearer when the absorbent article is worn. Further, when the wearable article is worn by the wearer, the side facing the wearer's skin is the skin surface side, and the opposite side is the non-skin surface side.

トップシート２は吸収体４の肌面側に配され、吸収性物品の着用の際に着用者の肌に面するように設けられる。トップシート２は、液透過性であることが好ましい。トップシート２としては、例えば、セルロース、レーヨン、コットン等の親水性繊維から形成された不織布や；ポリオレフィン（例えば、ポリプロピレン、ポリエチレン）、ポリエステル（例えば、ＰＥＴ）、ポリアミド（例えば、ナイロン）等の疎水性繊維から形成された不織布であって、疎水性繊維の表面が界面活性剤により親水化されたもの等を用いることができる。また、トップシート２として、織布、編布、有孔プラスチックフィルム等を用いてもよい。 The top sheet 2 is arranged on the skin surface side of the absorber 4 and is provided so as to face the wearer's skin when the absorbent article is worn. The top sheet 2 is preferably liquid permeable. The top sheet 2 includes, for example, a non-woven fabric formed from hydrophilic fibers such as cellulose, rayon, and cotton; and hydrophobic such as polyolefin (for example, polypropylene, polyethylene), polyester (for example, PET), and polyamide (for example, nylon). A non-woven fabric formed of rayon, in which the surface of the hydrophobic fiber is hydrophilized by a surfactant, or the like can be used. Further, as the top sheet 2, a woven cloth, a knitted cloth, a perforated plastic film or the like may be used.

バックシート３は吸収体４の非肌面側に配され、液不透過性であることが好ましい。バックシート３としては、ポリオレフィン（例えば、ポリプロピレン、ポリエチレン）、ポリエステル（例えば、ＰＥＴ）、ポリアミド（例えば、ナイロン）等の疎水性繊維から形成された不織布や、プラスチックフィルム等を用いることができる。また、バックシート３として、不織布とプラスチックフィルムとの積層体を用いてもよい。バックシート３の非肌面側は、吸収性物品をパンツやショーツ等の下着に取り付けて使用する際の下着対向面となる。 The back sheet 3 is preferably arranged on the non-skin surface side of the absorber 4 and is impermeable to liquid. As the back sheet 3, a non-woven fabric formed of hydrophobic fibers such as polyolefin (for example, polypropylene, polyethylene), polyester (for example, PET), and polyamide (for example, nylon), a plastic film, or the like can be used. Further, as the back sheet 3, a laminate of a non-woven fabric and a plastic film may be used. The non-skin surface side of the back sheet 3 serves as an underwear facing surface when the absorbent article is attached to underwear such as pants or shorts.

トップシート２やバックシート３として不織布を用いる場合、不織布としては、スパンボンド不織布、エアスルー不織布、ポイントボンド不織布、メルトブロー不織布、エアレイド不織布、ＳＭＳ不織布等を用いることが好ましい。 When a non-woven fabric is used as the top sheet 2 or the back sheet 3, it is preferable to use a spunbonded non-woven fabric, an air-through non-woven fabric, a point-bonded non-woven fabric, a melt-blown non-woven fabric, an air-laid non-woven fabric, an SMS non-woven fabric, or the like.

吸収体４は、尿等の排泄物を吸収できる吸収性材料を含むものであれば特に限定されない。吸収体４としては、例えば、吸収性材料を所定形状に成形した成形体を用いたり、あるいは当該成形体を紙シート（例えば、ティッシュペーパーや薄葉紙）や液透過性不織布シート等の被覆シートで覆ったものを用いることができる。吸収性材料としては、例えば、パルプ繊維等の親水性繊維や、ポリアクリル酸系、ポリアスパラギン酸系、セルロース系、デンプン・アクリロニトリル系等の吸水性樹脂等が挙げられる。また、吸水性材料には、ポリエチレン、ポリプロピレン等のポリオレフィン繊維や、ＰＥＴ等のポリエステル繊維、ポリアミド繊維等の熱融着性繊維が含まれてもよい。これらの熱融着性繊維は、尿等との親和性を高めるために、界面活性剤等により親水化処理がされていてもよい。 The absorber 4 is not particularly limited as long as it contains an absorbent material capable of absorbing excrement such as urine. As the absorber 4, for example, a molded body obtained by molding an absorbent material into a predetermined shape is used, or the molded body is covered with a covering sheet such as a paper sheet (for example, tissue paper or thin paper) or a liquid-permeable non-woven fabric sheet. Can be used. Examples of the absorbent material include hydrophilic fibers such as pulp fibers and water-absorbent resins such as polyacrylic acid-based, polyaspartic acid-based, cellulosic-based, and starch / acrylonitrile-based. Further, the water-absorbent material may include polyolefin fibers such as polyethylene and polypropylene, polyester fibers such as PET, and heat-sealing fibers such as polyamide fibers. These heat-sealing fibers may be hydrophilized with a surfactant or the like in order to enhance the affinity with urine or the like.

吸収性材料は、尿等の吸収速度を高める点から、親水性繊維を含むことが好ましい。また、吸収容量を高める点からは、吸収性材料は吸水性樹脂を含むことが好ましい。従って、吸収体４は親水性繊維（特にパルプ繊維）と吸水性樹脂を含むことが好ましい。この場合、例えば、親水性繊維の集合体に吸水性樹脂を混合または散布したものを用いることが好ましい。 The absorbent material preferably contains hydrophilic fibers from the viewpoint of increasing the absorption rate of urine and the like. Further, from the viewpoint of increasing the absorption capacity, the absorbent material preferably contains a water-absorbent resin. Therefore, the absorber 4 preferably contains hydrophilic fibers (particularly pulp fibers) and a water-absorbent resin. In this case, for example, it is preferable to use an aggregate of hydrophilic fibers mixed or sprayed with a water-absorbent resin.

吸収体４は、シート状吸収体であってもよい。シート状吸収体としては、不織布間に吸水性樹脂を有しパルプ繊維を有しないように形成されたものが挙げられる。このように形成されたシート状吸収体は、不織布間に吸水性樹脂を有するため、高い吸収容量を実現できる。また、シート状吸収体は不織布間にパルプ繊維を有しないため、嵩張らず薄型に形成することができる。 The absorber 4 may be a sheet-shaped absorber. Examples of the sheet-shaped absorber include those formed so as to have a water-absorbent resin between the non-woven fabrics and not to have pulp fibers. Since the sheet-shaped absorber formed in this way has a water-absorbent resin between the non-woven fabrics, a high absorption capacity can be realized. Further, since the sheet-shaped absorber does not have pulp fibers between the non-woven fabrics, it can be formed thin without being bulky.

吸収体４の形状（平面形状）は特に限定されない。吸収体４の形状は、用途に応じて適宜決定すればよく、例えば、略長方形、砂時計形、ひょうたん形、羽子板形等が挙げられる。 The shape (planar shape) of the absorber 4 is not particularly limited. The shape of the absorber 4 may be appropriately determined according to the intended use, and examples thereof include a substantially rectangular shape, an hourglass shape, a gourd shape, and a battledore shape.

図面では吸収体４とバックシート３との間に繊維シート５が設けられており、繊維シート５により吸収性物品１の形状保持性を向上させることができる。繊維シート５は、クレープ紙や不織布から構成することができる。 In the drawing, the fiber sheet 5 is provided between the absorber 4 and the back sheet 3, and the fiber sheet 5 can improve the shape retention of the absorbent article 1. The fiber sheet 5 can be made of crepe paper or non-woven fabric.

トップシート２の幅方向ｘの両側には立ち上がりフラップ６が設けられる。立ち上がりフラップ６により、尿等の横漏れが防止される。立ち上がりフラップ６は、バックシート３に使用可能なシート部材から構成することができ、液不透過性のプラスチックフィルムや液不透過性の不織布から構成されることが好ましい。立ち上がりフラップ６は、前側固定部６Ｆと後側固定部６Ｂとこれらの間の中間部６Ｍを有し、少なくとも中間部６Ｍに前後方向ｙに延びるフラップ弾性部材７が設けられ、前側固定部６Ｆと後側固定部６Ｂがトップシート２に接合されることにより、中間部６Ｍが起立可能に形成される。立ち上がりフラップ６の前側固定部６Ｆと後側固定部６Ｂは、直接または間接的にトップシート２に接合されればよく、これにより前側固定部６Ｆと後側固定部６Ｂが起立しないように形成されていればよい。 Rising flaps 6 are provided on both sides of the top sheet 2 in the width direction x. The rising flap 6 prevents lateral leakage of urine and the like. The rising flap 6 can be made of a sheet member that can be used for the back sheet 3, and is preferably made of a liquid-impermeable plastic film or a liquid-impermeable non-woven fabric. The rising flap 6 has a front fixing portion 6F, a rear fixing portion 6B, and an intermediate portion 6M between them, and at least the intermediate portion 6M is provided with a flap elastic member 7 extending in the front-rear direction y, and the front fixing portion 6F and the rising flap 6. By joining the posterior fixing portion 6B to the top sheet 2, the intermediate portion 6M is formed so as to be able to stand upright. The front fixing portion 6F and the rear fixing portion 6B of the rising flap 6 may be directly or indirectly joined to the top sheet 2, whereby the front fixing portion 6F and the rear fixing portion 6B are formed so as not to stand up. I just need to be there.

立ち上がりフラップ６は、立ち上がる起点となる基部と立ち上がった先端となる自由端を有し、基部と自由端の間にフラップ弾性部材７が設けられる。フラップ弾性部材７は伸張状態で立ち上がりフラップ６に接着剤等で固定されることが好ましく、フラップ弾性部材７の収縮力によって、立ち上がりフラップ６の起立が促進される。立ち上がりフラップ６は、トップシート２の幅方向ｘの両側に、前後方向ｙに延在するサイドシート８を接合し、サイドシート８の幅方向ｘの内方部にフラップ弾性部材７を設けることにより形成することができる。 The rising flap 6 has a base portion as a starting point for rising and a free end as a rising tip, and a flap elastic member 7 is provided between the base portion and the free end. It is preferable that the flap elastic member 7 stands up in an extended state and is fixed to the flap 6 with an adhesive or the like, and the contraction force of the flap elastic member 7 promotes the standing up of the rising flap 6. The rising flap 6 is formed by joining side sheets 8 extending in the front-rear direction y to both sides of the top sheet 2 in the width direction x, and providing flap elastic members 7 in the inner portion of the side sheet 8 in the width direction x. Can be formed.

図面に示した吸収性物品１では、サイドシート８が幅方向ｘの断面でＺ字状に折りたたまれており、折りたたまれたサイドシート８の自由端を含む面にフラップ弾性部材７が取り付けられている。すなわち、立ち上がりフラップ６は、基部から自由端の間で前後方向ｙに延びる折り返し線に沿って折り返されて、折り返し線と自由端の間にフラップ弾性部材７が設けられている。 In the absorbent article 1 shown in the drawing, the side sheet 8 is folded in a Z shape in a cross section in the width direction x, and the flap elastic member 7 is attached to the surface including the free end of the folded side sheet 8. There is. That is, the rising flap 6 is folded back along a folding line extending in the front-rear direction y from the base portion to the free end, and a flap elastic member 7 is provided between the folding line and the free end.

前側固定部６Ｆと後側固定部６Ｂでは、Ｚ字状に折りたたまれたサイドシート８の各面が相互に接合され、これにより前側固定部６Ｆと後側固定部６Ｂが間接的に（すなわちサイドシート８を介して）トップシート２に固定されている。また、このように前側固定部６Ｆと後側固定部６Ｂにおいてサイドシート８の各面が相互に接合されることにより、Ｚ字状の折りたたみが維持されることが好ましい。図面に示した吸収性物品１では、立ち上がりフラップ６の折り返し線より基部側の部分と自由端側の部分とが前側固定部６Ｆと後側固定部６Ｂにおいて一緒にエンボス処理されており、これによりＺ字状に折りたたまれたサイドシート８の各面が相互に接合されている。 In the front fixing portion 6F and the rear fixing portion 6B, each surface of the side sheet 8 folded in a Z shape is joined to each other, whereby the front fixing portion 6F and the rear fixing portion 6B are indirectly (that is, the side). It is fixed to the top sheet 2 (via the sheet 8). Further, it is preferable that the Z-shaped folding is maintained by joining the surfaces of the side sheets 8 to each other in the front fixing portion 6F and the rear fixing portion 6B in this way. In the absorbent article 1 shown in the drawing, the portion on the base side and the portion on the free end side of the folding line of the rising flap 6 are embossed together in the front fixing portion 6F and the rear fixing portion 6B. Each surface of the side sheet 8 folded in a Z shape is joined to each other.

吸収性物品１は、トップシート２の肌面側に粘着部９が設けられ、バックシート３の非肌面側に滑り止め部１０が設けられている。吸収性物品１をパンツやショーツ等の下着の肌面側に設置して装着した際、粘着部９は着用者の肌に面するように設けられ、滑り止め部１０は下着の肌面側に面するように設けられる。 The absorbent article 1 is provided with an adhesive portion 9 on the skin surface side of the top sheet 2 and a non-slip portion 10 on the non-skin surface side of the back sheet 3. When the absorbent article 1 is installed and worn on the skin side of underwear such as pants or shorts, the adhesive portion 9 is provided so as to face the wearer's skin, and the non-slip portion 10 is on the skin surface side of the underwear. It is provided so as to face it.

粘着部９は、トップシート２の肌面側において、前側固定部６Ｆの後側端よりも前側および後側固定部６Ｂの前側端よりも後側にそれぞれ設けられ、滑り止め部１０は、バックシート３の非肌面側において、前側固定部６Ｆの後側端よりも後側かつ後側固定部６Ｂの前側端よりも前側に設けられる。吸収性物品１はこのように粘着部９と滑り止め部１０が設けられることにより、着用者の股間に好適に装着することができるとともに、尿等の漏れを効果的に防止できる。すなわち吸収性物品１は、トップシート２の肌面側に設けられた粘着部９によって着用者の股間部の肌に貼り付けることができ、着用者の股間の所望の位置に密着性良く設置することができる。この際、前側固定部６Ｆの後側端よりも前側および後側固定部６Ｂの前側端よりも後側に粘着部９を設けることによって、立ち上がりフラップ６の中間部６Ｍを好適に起立させることができ、尿等の横漏れを効果的に防止することができる。また、粘着部９は排尿部から離れた位置に設けられるため、粘着部９が尿等によって濡れにくくなり、粘着力を長く持続させやすくなる。一方、バックシート３の非肌面側に設けられた滑り止め部１０によって、吸収性物品１をパンツやショーツ等の下着の所定の位置に設置することができ、吸収性物品１が下着からはみ出したりすることを防ぐことができる。また、粘着部ではなく滑り止め部１０をバックシート３の非肌面側に設けることにより、バックシート３と下着との間のずれ応力が大きくなったときに、当該ずれ応力を緩和するように互いの接触位置をずらすことができるため、吸収性物品１や下着に大きな歪みやしわが生じにくくなる。これにより、下着の見栄えを良くすることができるとともに、吸収性物品１の着用者の肌への密着性も高めることができる。 The adhesive portion 9 is provided on the skin surface side of the top sheet 2 on the front side of the front side fixing portion 6F and on the rear side of the front side end of the rear side fixing portion 6B, and the non-slip portion 10 is provided on the back side. On the non-skin surface side of the sheet 3, it is provided on the rear side of the rear end of the front fixing portion 6F and on the front side of the front end of the rear fixing portion 6B. By providing the adhesive portion 9 and the non-slip portion 10 in this way, the absorbent article 1 can be suitably worn in the crotch of the wearer and can effectively prevent leakage of urine and the like. That is, the absorbent article 1 can be attached to the skin of the wearer's crotch portion by the adhesive portion 9 provided on the skin surface side of the top sheet 2, and is installed at a desired position of the wearer's crotch with good adhesion. be able to. At this time, by providing the adhesive portion 9 on the front side of the front side fixing portion 6F and on the rear side of the front side end of the rear side fixing portion 6B, the intermediate portion 6M of the rising flap 6 can be suitably raised. It is possible to effectively prevent lateral leakage of urine and the like. Further, since the adhesive portion 9 is provided at a position away from the urination portion, the adhesive portion 9 is less likely to get wet by urine or the like, and the adhesive force can be easily maintained for a long time. On the other hand, the non-slip portion 10 provided on the non-skin surface side of the back sheet 3 allows the absorbent article 1 to be installed at a predetermined position of underwear such as pants and shorts, and the absorbent article 1 protrudes from the underwear. It is possible to prevent it from happening. Further, by providing the non-slip portion 10 instead of the adhesive portion on the non-skin surface side of the back sheet 3, when the displacement stress between the back sheet 3 and the underwear becomes large, the displacement stress is relaxed. Since the contact positions can be shifted from each other, the absorbent article 1 and the underwear are less likely to be greatly distorted or wrinkled. As a result, the appearance of the underwear can be improved, and the adhesion of the absorbent article 1 to the skin of the wearer can be improved.

以下において、前側固定部６Ｆの後側端よりも前側に設けられた粘着部を「粘着部９Ｆ」と称し、後側固定部６Ｂの前側端より後側に設けられた粘着部を「粘着部９Ｂ」と称する。また、粘着部９Ｆと粘着部９Ｂをまとめて粘着部９と称する場合がある。 In the following, the adhesive portion provided on the front side of the front end of the front fixing portion 6F is referred to as "adhesive portion 9F", and the adhesive portion provided on the rear side of the rear fixing portion 6B from the front end is referred to as "adhesive portion". It is called "9B". Further, the adhesive portion 9F and the adhesive portion 9B may be collectively referred to as the adhesive portion 9.

粘着部９は、吸収体４の前側端または後側端と重なって設けられるか、それよりも前後方向ｙの外方に設けられることが好ましい。具体的には、前側固定部６Ｆの後側端よりも前側に設けられる粘着部９Ｆは、吸収体４の前側端と重なって設けられるか、当該前側端よりも前側に設けられ、後側固定部６Ｂの前側端より後側に設けられる粘着部９Ｂは、吸収体４の後側端と重なって設けられるか、当該後側端よりも後側に設けられることが好ましい。このように粘着部９を設けることにより、吸収性物品１を安定して着用者の肌に貼り付けることができる。また、吸収体４のより広い範囲が尿等の吸収に寄与できるものとなる。 The adhesive portion 9 is preferably provided so as to overlap the front end or the rear end of the absorber 4, or is provided outside in the front-rear direction y. Specifically, the adhesive portion 9F provided on the front side of the front end of the front fixing portion 6F is provided so as to overlap the front end of the absorber 4 or is provided on the front side of the front end and fixed on the rear side. The adhesive portion 9B provided on the rear side of the front end of the portion 6B is preferably provided so as to overlap the rear end of the absorber 4, or is provided on the rear side of the rear end. By providing the adhesive portion 9 in this way, the absorbent article 1 can be stably attached to the wearer's skin. In addition, a wider range of the absorber 4 can contribute to the absorption of urine and the like.

吸収性物品１をより安定して着用者の肌に固定する点からは、粘着部９Ｆは吸収体４の前側端と重なって設けられ、粘着部９Ｂは吸収体４の後側端と重なって設けられることが好ましい。吸収性物品１は、吸収体４の前側端と後側端において剛性が不連続的に変化することにより、吸収体４の前側端と後側端に沿って折れ曲がりやすくなる。しかし、粘着部９Ｆを吸収体４の前側端と重なって設け、粘着部９Ｂを吸収体４の後側端と重なって設けることにより、吸収性物品１が吸収体４の前側端と後側端に沿って折れ曲がることを抑えることができる。特に、吸収性物品１を装着する際に吸収性物品１の前後端部の折れ曲がりを防ぐことで、吸収性物品１を着用者の肌に取り付けることが容易になる。 From the point of fixing the absorbent article 1 to the wearer's skin more stably, the adhesive portion 9F is provided so as to overlap the front end of the absorber 4, and the adhesive portion 9B overlaps with the rear end of the absorber 4. It is preferable to be provided. Since the rigidity of the absorbent article 1 changes discontinuously at the front end and the rear end of the absorber 4, the absorbent article 1 tends to bend along the front end and the rear end of the absorber 4. However, by providing the adhesive portion 9F so as to overlap the front end of the absorber 4 and the adhesive portion 9B so as to overlap the rear end of the absorber 4, the absorbent article 1 is provided at the front end and the rear end of the absorber 4. It is possible to prevent bending along the line. In particular, by preventing the front and rear ends of the absorbent article 1 from bending when the absorbent article 1 is attached, the absorbent article 1 can be easily attached to the wearer's skin.

粘着部９Ｆは、１つのみ設けられてもよく、複数設けられてもよい。後者の場合、粘着部９Ｆは、幅方向ｘおよび／または前後方向ｙに複数並んで設けられてもよい。粘着部９Ｂは、１つのみ設けられてもよく、複数設けられてもよい。後者の場合、粘着部９Ｂは、幅方向ｘおよび／または前後方向ｙに複数並んで設けられてもよい。なお、粘着部９Ｆは、前側固定部６Ｆの後側端よりも後側には設けられないことが好ましく、粘着部９Ｂは、後側固定部６Ｂの前側端よりも後側には設けられないことが好ましい。 Only one adhesive portion 9F may be provided, or a plurality of adhesive portions 9F may be provided. In the latter case, a plurality of adhesive portions 9F may be provided side by side in the width direction x and / or the front-rear direction y. Only one adhesive portion 9B may be provided, or a plurality of adhesive portions 9B may be provided. In the latter case, a plurality of adhesive portions 9B may be provided side by side in the width direction x and / or the front-rear direction y. It is preferable that the adhesive portion 9F is not provided on the rear side of the rear end of the front fixing portion 6F, and the adhesive portion 9B is not provided on the rear side of the front end of the rear fixing portion 6B. Is preferable.

粘着部９Ｆおよび粘着部９Ｂは、前後方向ｙの長さが５ｍｍ以上であることが好ましく、１０ｍｍ以上がより好ましく、また５０ｍｍ以下が好ましく、４０ｍｍ以下がより好ましく、３０ｍｍ以下がさらに好ましい。粘着部９Ｆ，９Ｂが前後方向ｙに複数並んで設けられる場合は、複数並んで設けられた粘着部９Ｆまたは複数並んで設けられた粘着部９Ｂの全体の前後方向ｙの長さがこのような範囲にあることが好ましい。このように粘着部９を設けることにより、粘着部９の設置面積を減らしつつ、吸収性物品１を着用者の肌に安定して位置固定することができる。 The adhesive portion 9F and the adhesive portion 9B preferably have a length y in the front-rear direction of 5 mm or more, more preferably 10 mm or more, preferably 50 mm or less, more preferably 40 mm or less, and further preferably 30 mm or less. When a plurality of adhesive portions 9F and 9B are provided side by side in the front-rear direction y, the length of the entire front-rear direction y of the plurality of adhesive portions 9F provided side by side or the plurality of adhesive portions 9B provided side by side is such. It is preferably in the range. By providing the adhesive portion 9 in this way, the absorbent article 1 can be stably fixed to the wearer's skin while reducing the installation area of the adhesive portion 9.

粘着部９Ｆは、幅方向ｘの一方側の前側固定部６Ｆよりも幅方向ｘの内方および幅方向ｘの他方側の前側固定部６Ｆよりも幅方向ｘの内方に設けられることが好ましい。粘着部９Ｂは、幅方向ｘの一方側の後側固定部６Ｂよりも幅方向ｘの内方および幅方向ｘの他方側の後側固定部６Ｂよりも幅方向ｘの内方に設けられることが好ましい。このように粘着部９が設けられることにより、立ち上がりフラップ６の中間部６Ｍが高く立ち上がりやすくなり、尿等の横漏れ防止効果が高まる。 The adhesive portion 9F is preferably provided inward in the width direction x than the front fixing portion 6F on one side in the width direction x and inward in the width direction x than the front fixing portion 6F on the other side in the width direction x. .. The adhesive portion 9B is provided inside the width direction x from the rear fixing portion 6B on one side in the width direction x and inside the width direction x from the rear fixing portion 6B on the other side in the width direction x. Is preferable. By providing the adhesive portion 9 in this way, the intermediate portion 6M of the rising flap 6 is raised and easily rises, and the effect of preventing lateral leakage of urine or the like is enhanced.

粘着部９Ｆは、吸収性物品１の幅方向ｘの中心には設けられず、幅方向ｘの一方側と他方側に設けられてもよい。粘着部９Ｂは、吸収性物品１の幅方向ｘの中心には設けられず、幅方向ｘの一方側と他方側に設けられてもよい。特に粘着部９Ｂはこのように設けられることが好ましく、これにより吸収性物品１を着用者の臀部に好適に取り付けやすくなる。 The adhesive portion 9F is not provided at the center of the absorbent article 1 in the width direction x, but may be provided on one side and the other side of the width direction x. The adhesive portion 9B is not provided at the center of the absorbent article 1 in the width direction x, but may be provided on one side and the other side of the width direction x. In particular, the adhesive portion 9B is preferably provided in this way, which makes it easier to suitably attach the absorbent article 1 to the wearer's buttocks.

バックシート３の非肌面側に設けられる滑り止め部１０は、少なくとも前側固定部６Ｆの後側端よりも後側かつ後側固定部６Ｂの前側端よりも前側に設けられ、前側固定部６Ｆの後側端よりも前側および／または後側固定部６Ｂの前側端よりも後側にも設けられてもよい。滑り止め部１０は粘着部９と重なって設けられてもよいが、この場合、下着の外側からの動きが滑り止め部１０と粘着部９を介して着用者の肌に直接伝わりやすくなり、粘着部９において着用者の肌に無理な力がかかったり、粘着部９が肌から剥がれやすくなる。そのため、滑り止め部１０は粘着部９と重なって設けられないことが好ましい。より好ましくは、滑り止め部１０は粘着部９Ｆよりも後側かつ粘着部９Ｂの前側のみに設けられる。滑り止め部１０はまた、前側固定部６Ｆの後側端よりも後側かつ後側固定部６Ｂの前側端よりも前側のみに設けられることも好ましい。 The non-slip portion 10 provided on the non-skin surface side of the back sheet 3 is provided at least on the rear side of the rear end of the front fixing portion 6F and on the front side of the front end of the rear fixing portion 6B, and is provided on the front fixing portion 6F. It may be provided on the front side of the rear end and / or on the rear side of the front end of the rear fixing portion 6B. The non-slip portion 10 may be provided so as to overlap with the adhesive portion 9, but in this case, the movement from the outside of the underwear is easily transmitted directly to the wearer's skin via the non-slip portion 10 and the adhesive portion 9, and is adhesive. Unreasonable force is applied to the wearer's skin in the portion 9, and the adhesive portion 9 is easily peeled off from the skin. Therefore, it is preferable that the non-slip portion 10 is not provided so as to overlap the adhesive portion 9. More preferably, the non-slip portion 10 is provided only on the posterior side of the adhesive portion 9F and on the front side of the adhesive portion 9B. It is also preferable that the non-slip portion 10 is provided only on the rear side of the rear end of the front fixing portion 6F and on the front side of the front end of the rear fixing portion 6B.

滑り止め部１０は、前後方向ｙに並んで複数設けられることが好ましい。このように滑り止め部１０を設けることにより、吸収性物品１を前後方向ｙに湾曲させることが容易になり、吸収性物品１の着用者の股間部へのフィット性を高めることができる。前後方向ｙに並んで設けられた各滑り止め部１０は、幅方向ｘに長い形状で、幅方向ｘに連続的に延在することが好ましい。 It is preferable that a plurality of non-slip portions 10 are provided side by side in the front-rear direction y. By providing the non-slip portion 10 in this way, the absorbent article 1 can be easily curved in the front-rear direction y, and the fit of the absorbent article 1 to the wearer's crotch portion can be improved. It is preferable that the non-slip portions 10 provided side by side in the front-rear direction y have a long shape in the width direction x and extend continuously in the width direction x.

滑り止め部１０は、前後方向ｙに並んで４個以上設けられることが好ましく、８個以上がより好ましく、１２個以上がさらに好ましい。滑り止め部１０の設置数の上限は特に限定されず、滑り止め部１０は前後方向ｙに並んで例えば６０個以下設けられてもよく、４０個以下、または３０個以下設けられてもよい。１つの滑り止め部１０の前後方向ｙの長さは、滑り止め部１０によるズレ止め効果を高める点から、１ｍｍ以上が好ましく、３ｍｍ以上がより好ましく、５ｍｍ以上がさらに好ましい。一方、吸収性物品１を前後方向ｙにスムーズに湾曲させやすくする点から、１つの滑り止め部１０の前後方向ｙの長さは３０ｍｍ以下が好ましく、２５ｍｍ以下がより好ましく、２０ｍｍ以下がさらに好ましい。滑り止め部１０の幅方向ｘの長さは、２０ｍｍ以上が好ましく、２５ｍｍ以上がより好ましく、３０ｍｍ以上がさらに好ましい。 It is preferable that four or more non-slip portions 10 are provided side by side in the front-rear direction y, more preferably eight or more, and even more preferably 12 or more. The upper limit of the number of non-slip portions 10 to be installed is not particularly limited, and for example, 60 or less anti-slip portions 10 may be provided side by side in the front-rear direction y, 40 or less, or 30 or less. The length y of one anti-slip portion 10 in the front-rear direction is preferably 1 mm or more, more preferably 3 mm or more, still more preferably 5 mm or more, from the viewpoint of enhancing the anti-slip effect of the anti-slip portion 10. On the other hand, the length of one non-slip portion 10 in the front-rear direction y is preferably 30 mm or less, more preferably 25 mm or less, still more preferably 20 mm or less, from the viewpoint of facilitating the smooth bending of the absorbent article 1 in the front-rear direction y. .. The length of the non-slip portion 10 in the width direction x is preferably 20 mm or more, more preferably 25 mm or more, still more preferably 30 mm or more.

滑り止め部１０は、吸収体４と重なって設けられることが好ましく、吸収体４よりも幅方向ｘに狭く形成されていることが好ましい。すなわち、滑り止め部１０は、吸収体４の幅方向ｘの一方端および他方端よりも幅方向ｘの外方に延在しないように設けられることが好ましい。このように滑り止め部１０を設けることにより、吸収性物品１の幅方向ｘの両端部の下着の動きへの滑り性が高まる。そのため、吸収性物品１を下着に取り付けた状態で着用者が大腿部を大きく動かしても、吸収性物品１に歪みが生じにくくなる。 The non-slip portion 10 is preferably provided so as to overlap with the absorber 4, and is preferably formed narrower in the width direction x than the absorber 4. That is, it is preferable that the non-slip portion 10 is provided so as not to extend outward in the width direction x from one end and the other end of the width direction x of the absorber 4. By providing the non-slip portion 10 in this way, the slipperiness of the absorbent article 1 to the movement of the underwear at both ends in the width direction x is enhanced. Therefore, even if the wearer moves the thigh part greatly with the absorbent article 1 attached to the underwear, the absorbent article 1 is less likely to be distorted.

吸収体４は、図４に示すように、高剛性部１１と低剛性部１２とを有し、高剛性部１１と低剛性部１２が幅方向ｘに交互に並んで配置されているものであってもよい。このように吸収体４が形成されていれば、吸収性物品１が着用者の両大腿部に挟まれて幅方向ｘの内方に向かう力がかかっても、吸収体４に不規則な折り目が形成されにくくなり、幅方向ｘの内方に向かう力を好適に吸収することができる。例えば吸収性物品１に幅方向ｘの内方に向かう力がかかると、吸収体４が低剛性部１２で撓んで幅方向ｘに狭まることができる。一方、そのような力が吸収体４にかかっても、吸収体４の高剛性部１１は変形が抑えられ、吸収体４全体としては平面性が保たれやすくなる。そのため、吸収体４が大きく歪みにくくなり、吸収性物品１の着用感が向上するとともに、着用者から排泄された尿等が吸収体４によって好適に吸収されやすくなる。 As shown in FIG. 4, the absorber 4 has a high-rigidity portion 11 and a low-rigidity portion 12, and the high-rigidity portion 11 and the low-rigidity portion 12 are arranged alternately in the width direction x. There may be. When the absorber 4 is formed in this way, even if the absorbent article 1 is sandwiched between both thighs of the wearer and a force is applied inward in the width direction x, the absorber 4 is irregular. The creases are less likely to be formed, and the inward force in the width direction x can be suitably absorbed. For example, when an inward force is applied to the absorbent article 1 in the width direction x, the absorber 4 can bend at the low-rigidity portion 12 and narrow in the width direction x. On the other hand, even if such a force is applied to the absorber 4, the high-rigidity portion 11 of the absorber 4 is suppressed from being deformed, and the flatness of the absorber 4 as a whole is easily maintained. Therefore, the absorber 4 is largely less likely to be distorted, the wearing feeling of the absorbent article 1 is improved, and the urine or the like excreted from the wearer is easily absorbed by the absorber 4.

高剛性部１１と低剛性部１２はそれぞれ、吸収体４の前後方向ｙに延在し、高剛性部１１と低剛性部１２が幅方向ｘに交互に並んで配されていることが好ましい。すなわち高剛性部１１と低剛性部１２は、吸収体４の前後方向ｙに延びるストライプ状に配置されている好ましい。高剛性部１１は幅方向ｘに並んで３個以上設けられることが好ましく、また８個以下が好ましく、６個以下がより好ましい。低剛性部１２は幅方向ｘに並んで３個以上設けられることがより好ましく、また９個以下が好ましく、７以個下がより好ましい。なお、高剛性部１１と低剛性部１２はそれぞれ、吸収体４の前後方向ｙの全体にわたって延在していることが好ましい。 It is preferable that the high-rigidity portion 11 and the low-rigidity portion 12 extend in the front-rear direction y of the absorber 4, respectively, and the high-rigidity portion 11 and the low-rigidity portion 12 are arranged alternately in the width direction x. That is, the high-rigidity portion 11 and the low-rigidity portion 12 are preferably arranged in a stripe shape extending in the front-rear direction y of the absorber 4. It is preferable that three or more high-rigidity portions 11 are provided side by side in the width direction x, preferably 8 or less, and more preferably 6 or less. It is more preferable that three or more low-rigidity portions 12 are provided side by side in the width direction x, preferably nine or less, and more preferably seven or less. It is preferable that the high-rigidity portion 11 and the low-rigidity portion 12 extend over the entire front-rear direction y of the absorber 4, respectively.

高剛性部１１は低剛性部１２よりも相対的に剛性が高く形成されている。高剛性部１１と低剛性部１２は、例えば次のように形成することができる。（１）高剛性部１１の目付を低剛性部１２の目付よりも大きくする、（２）吸収体４が繊維集合体を主成分として含み、高剛性部１１において繊維集合体が圧密される、（３）吸収体４がシート部材の間に吸水性樹脂を有しパルプ繊維を有しないように構成され、高剛性部１１の方が低剛性部１２よりも単位面積当たりの吸水性樹脂の量が多く形成される。 The high-rigidity portion 11 is formed to have a relatively higher rigidity than the low-rigidity portion 12. The high-rigidity portion 11 and the low-rigidity portion 12 can be formed, for example, as follows. (1) The texture of the high-rigidity portion 11 is made larger than the texture of the low-rigidity portion 12, and (2) the absorber 4 contains the fiber aggregate as a main component, and the fiber aggregate is compacted in the high-rigidity portion 11. (3) The absorber 4 is configured to have a water-absorbent resin between the sheet members and not to have pulp fibers, and the high-rigidity portion 11 has a higher rigidity portion 11 than the low-rigidity portion 12 in the amount of the water-absorbent resin per unit area. Is formed in large numbers.

高剛性部１１と低剛性部１２の１つ当たりの幅方向ｘの長さは特に限定されないが、高剛性部１１の幅方向ｘの長さの方が低剛性部１２の幅方向ｘの長さよりも長いことが好ましい。具体的には、高剛性部１１は全て低剛性部１２よりも幅方向ｘの長さが長いことが好ましい。これにより、吸収体４の保形性を高めることができ、吸収体４に幅方向ｘの内方に向かう力がかからない場合に、吸収体４が平面状に形成されやすくなる。高剛性部１１と低剛性部１２の幅方向ｘの長さの比は、高剛性部１１の幅方向ｘの長さ（平均値）／低剛性部１２の幅方向ｘの長さ（平均値）として、５０／５０より大きいことが好ましく、６０／４０以上がより好ましく、また９５／５以下が好ましく、９０／１０以下がより好ましく、８５／１５以下がさらに好ましい。 The length of each of the high-rigidity portion 11 and the low-rigidity portion 12 in the width direction x is not particularly limited, but the length of the high-rigidity portion 11 in the width direction x is the length of the low-rigidity portion 12 in the width direction x. It is preferably longer than that. Specifically, it is preferable that all the high-rigidity portions 11 have a longer length in the width direction x than the low-rigidity portions 12. As a result, the shape-retaining property of the absorber 4 can be enhanced, and when the absorber 4 is not subjected to an inward force in the width direction x, the absorber 4 is likely to be formed in a flat shape. The ratio of the length of the high-rigidity portion 11 and the length of the low-rigidity portion 12 in the width direction x is the length of the high-rigidity portion 11 in the width direction x (average value) / the length of the low-rigidity portion 12 in the width direction x (average value). ), It is preferably larger than 50/50, more preferably 60/40 or more, preferably 95/5 or less, more preferably 90/10 or less, and further preferably 85/15 or less.

上記のように吸収体４が形成される場合、滑り止め部１０は、複数の高剛性部１１に跨がって設けられることが好ましい。上記に説明したように、吸収性物品１は幅方向ｘの内方に向かう力がかかると、吸収体４が低剛性部１２で撓みやすくなるが、滑り止め部１０が複数の高剛性部１１に跨がって設けられることにより、吸収性物品１に幅方向ｘへの剛性が付与され、吸収性物品１の幅方向ｘの内方に向かう力が解除されると、吸収性物品１がもとの平面状に広がりやすくなる。また、高剛性部１１では滑り止め部１０と下着との接触が維持され、滑り止め部１０が当初の下着の固定位置に維持されやすくなる。滑り止め部１０は、吸収体４の幅方向ｘの一方端に最も近い高剛性部１１と吸収体４の幅方向ｘの他方端に最も近い高剛性部１１とに跨がって設けられることがより好ましい。 When the absorber 4 is formed as described above, the non-slip portion 10 is preferably provided so as to straddle the plurality of high-rigidity portions 11. As described above, in the absorbent article 1, when a force is applied inward in the width direction x, the absorber 4 tends to bend in the low-rigidity portion 12, but the non-slip portion 10 has a plurality of high-rigidity portions 11. When the absorbent article 1 is provided with rigidity in the width direction x and the inward force of the absorbent article 1 in the width direction x is released, the absorbent article 1 is provided. It becomes easy to spread to the original plane. Further, in the high-rigidity portion 11, the contact between the non-slip portion 10 and the underwear is maintained, and the non-slip portion 10 is easily maintained at the initial fixed position of the underwear. The non-slip portion 10 is provided so as to straddle the high-rigidity portion 11 closest to one end of the width direction x of the absorber 4 and the high-rigidity portion 11 closest to the other end of the width direction x of the absorber 4. Is more preferable.

吸収体４は、不織布間に吸水性樹脂を有しパルプ繊維を有しないように構成されたシート状吸収体であってもよい。この場合、吸収体４は、複数層のシート部材を有し、シート部材の間に吸水性樹脂が配され、パルプ繊維が配されないように構成される。なお、シート部材間には、製造上不可避的に混入するパルプ繊維の存在は許容される。このように吸収体４が構成されることにより、吸収体４を高い吸収容量を有しつつ薄型に形成することができる。 The absorber 4 may be a sheet-like absorber configured to have a water-absorbent resin between the non-woven fabrics and not to have pulp fibers. In this case, the absorber 4 has a plurality of layers of sheet members, and the water-absorbent resin is arranged between the sheet members so that the pulp fibers are not arranged. It should be noted that the presence of pulp fibers inevitably mixed in the sheet members is allowed in the manufacturing process. By constructing the absorber 4 in this way, the absorber 4 can be formed thin while having a high absorption capacity.

シート部材は液透過性であり、トップシート２に使用可能なシート部材を用いることができる。シート部材としては、不織布製シート部材、すなわち不織布シートを用いることが好ましい。 The sheet member is liquid permeable, and a sheet member that can be used for the top sheet 2 can be used. As the sheet member, it is preferable to use a non-woven fabric sheet member, that is, a non-woven fabric sheet.

吸収体４は、シート部材どうしが接合された封止部と、シート部材どうしが接合されない非封止部とを有し、非封止部に吸水性樹脂が配されることが好ましい。封止部は、シート部材どうしを接着剤で接合したり、溶着（ヒートシールや超音波溶着等）することにより形成される。非封止部は、シート部材どうしが接合されない部分として規定され、封止部以外の部分が非封止部に相当する。封止部には吸水性樹脂が配されなくてもよいが、少量の吸水性樹脂が存在する場合もありうる。このように吸収体４が構成されることにより、封止部において尿等の拡散性が高められるとともに、非封止部において尿等が好適に吸収されることにより、吸収体４の吸収性能を高めることができる。この場合、吸収体４のより広い範囲が尿等の吸収に寄与できるようにする点から、尿等は前後方向ｙへの拡散性が高められることが好ましく、従って、封止部と非封止部は吸収体４の前後方向ｙに延在し、幅方向ｘに交互に並んで配されることが好ましい。 It is preferable that the absorber 4 has a sealing portion in which the sheet members are bonded to each other and a non-sealing portion in which the sheet members are not bonded to each other, and a water-absorbent resin is arranged in the non-sealing portion. The sealing portion is formed by joining the sheet members with an adhesive or welding (heat sealing, ultrasonic welding, etc.). The unsealed portion is defined as a portion where the sheet members are not joined to each other, and the portion other than the sealed portion corresponds to the unsealed portion. A water-absorbent resin may not be arranged on the sealing portion, but a small amount of water-absorbent resin may be present. By constructing the absorber 4 in this way, the diffusibility of urine or the like is enhanced in the sealed portion, and urine or the like is suitably absorbed in the non-sealed portion, thereby improving the absorption performance of the absorber 4. Can be enhanced. In this case, the diffusivity of urine or the like in the anteroposterior direction y is preferably enhanced from the viewpoint that a wider range of the absorber 4 can contribute to the absorption of urine or the like, and therefore, the sealed portion and the unsealed portion are not sealed. It is preferable that the portions extend in the front-rear direction y of the absorber 4 and are arranged alternately in the width direction x.

上記のように構成された吸収体４においては、吸水性樹脂が基本的に非封止部に配されることにより、非封止部の剛性が封止部の剛性よりも高くなる。そのため、非封止部が高剛性部として機能し、封止部が低剛性部として機能することができる。封止部と非封止部の配置等の詳細や封止部と非封止部と滑り止め部や粘着部との関係の詳細は、上記の説明において、「高剛性部」を「非封止部」と読み替え、「低剛性部」を「封止部」と読み替えることにより、参照される。 In the absorber 4 configured as described above, since the water-absorbent resin is basically arranged in the non-sealing portion, the rigidity of the non-sealing portion becomes higher than the rigidity of the sealing portion. Therefore, the unsealed portion can function as a high-rigidity portion, and the sealed portion can function as a low-rigidity portion. For details on the arrangement of the sealed portion and the non-sealed portion and the details of the relationship between the sealed portion and the non-sealed portion and the non-slip portion and the adhesive portion, the "high rigidity portion" is referred to as "unsealed" in the above description. It is referred to by reading "stop portion" and "low rigidity portion" as "sealing portion".

The adhesive usually contains 10% by mass or more of a tackifier component in order to exhibit adhesiveness and tackiness, but the resin layer of the non-slip portion 10 contains a large amount of such a tackifier component. It is preferable that there is no such thing. Examples of the tackifying component include rosin-based resin, terpene-based resin, dicyclopentadiene resin, C5-based or C9-based hydrocarbon resin, alicyclic hydrocarbon resin, and the like.

As a result, the visibility of the adhesive portion 9 is enhanced, and the wearer can easily attach the adhesive portion 9 to a desired position on the skin of the crotch portion while looking at the adhesive portion 9.

吸収性物品１は、前後方向ｙに３つ折りされて折り畳まれたものであってもよい。図５には、前後方向に３つ折りされる吸収性物品を肌面側から見た平面図を示し、図６には、図５に示した吸収性物品を非肌面側から見た平面図を示した。 The absorbent article 1 may be folded in three in the front-rear direction y. FIG. 5 shows a plan view of the absorbent article folded in three in the front-rear direction as viewed from the skin surface side, and FIG. 6 is a plan view of the absorbent article shown in FIG. 5 as viewed from the non-skin surface side. showed that.

吸収性物品１が前後方向ｙに３つ折りされる場合、吸収性物品１は、肌面側を内側にして、幅方向ｘに延びる第１の折り目Ｆ１とそれより後側に位置する第２の折り目Ｆ２で折り返されることが好ましい。この場合、粘着部９は、第１の折り目Ｆ１よりも前側および第２の折り目Ｆ２よりも後側にそれぞれ設けられることが好ましい。このように折り畳まれた吸収性物品１は、吸収性物品１の折り畳みを展開して着用者の股間に取り付ける際、第１の折り目Ｆ１と第２の折り目Ｆ２の折り癖によって、吸収性物品１の第１の折り目Ｆ１よりも前側の部分および第２の折り目Ｆ２よりも後側の部分が着用者の肌に向かって立ち上がりやすくなる。そのため、当該部分に粘着部９を設けることにより、粘着部９によって吸収性物品１を着用者の肌に好適に取り付けやすくなる。この場合、前側固定部６Ｆの後側端は第１の折り目Ｆ１よりも前側に位置し、後側固定部６Ｂの前側端は第２の折り目Ｆ２よりも後側に位置することが好ましい。 When the absorbent article 1 is folded in three in the front-rear direction y, the absorbent article 1 has a first crease F1 extending in the width direction x with the skin surface side inward and a second crease F1 located behind the first crease F1. It is preferable to fold back at the crease F2. In this case, it is preferable that the adhesive portion 9 is provided on the front side of the first fold F1 and on the rear side of the second fold F2, respectively. When the absorbent article 1 folded in this way is unfolded and attached to the wearer's crotch, the absorbent article 1 is caused by the fold habit of the first fold F1 and the second fold F2. The portion on the front side of the first fold F1 and the portion on the rear side of the second fold F2 are likely to stand up toward the wearer's skin. Therefore, by providing the adhesive portion 9 in the portion, the adhesive portion 9 makes it easier to suitably attach the absorbent article 1 to the wearer's skin. In this case, it is preferable that the rear end of the front fixing portion 6F is located on the front side of the first crease F1 and the front end of the rear fixing portion 6B is located on the rear side of the second fold F2.

上記のように吸収性物品１が前後方向ｙに３つ折りされる場合、滑り止め部１０は、少なくとも第１の折り目Ｆ１と第２の折り目Ｆ２の間に設けられることが好ましい。滑り止め部１０は、第１の折り目Ｆ１よりも前側および／または第２の折り目Ｆ２よりも後側にも設けられてもよいが、滑り止め部１０は粘着部９からある程度離れて設けられることが、粘着部９において着用者の肌に無理な力がかかりにくくなる点から好ましい。従って、滑り止め部１０は、第１の折り目Ｆ１と第２の折り目Ｆ２の間のみに設けられることが好ましい。 When the absorbent article 1 is folded in three in the front-rear direction y as described above, the non-slip portion 10 is preferably provided at least between the first fold F1 and the second fold F2. The non-slip portion 10 may be provided on the front side of the first crease F1 and / or on the rear side of the second crease F2, but the non-slip portion 10 is provided at a certain distance from the adhesive portion 9. However, it is preferable because the adhesive portion 9 is less likely to apply an excessive force to the wearer's skin. Therefore, it is preferable that the non-slip portion 10 is provided only between the first crease F1 and the second crease F2.

滑り止め部１０は、第１の折り目Ｆ１またはその近傍および第２の折り目Ｆ２またはその近傍に少なくとも設けられることが好ましい。具体的には、滑り止め部１０は、第１の折り目Ｆ１から前後方向ｙに１０ｍｍ以内の領域に設けられるとともに、第２の折り目Ｆ２から前後方向ｙに１０ｍｍ以内の領域に設けられることが好ましい。第１の折り目Ｆ１とその近傍および第２の折り目Ｆ２とその近傍では、折り畳まれた吸収性物品１を展開した際に、当該部分で吸収性物品１が下着と接しやすくなる。従って、第１の折り目Ｆ１またはその近傍および第２の折り目Ｆ２またはその近傍に滑り止め部１０を設けることにより、吸収性物品１をパンツやショーツ等の下着の所定の位置に固定させやすくなる。 It is preferable that the non-slip portion 10 is provided at least in the first crease F1 or its vicinity and in the second crease F2 or its vicinity. Specifically, it is preferable that the non-slip portion 10 is provided in a region within 10 mm in the front-rear direction y from the first crease F1 and in a region within 10 mm in the front-rear direction y from the second fold F2. .. At the first fold F1 and its vicinity and at the second crease F2 and its vicinity, when the folded absorbent article 1 is unfolded, the absorbent article 1 easily comes into contact with the underwear at that portion. Therefore, by providing the non-slip portion 10 at or near the first fold F1 and at or near the second crease F2, the absorbent article 1 can be easily fixed at a predetermined position of underwear such as pants or shorts.

吸収性物品１の保形性を高める点から、吸収体４とバックシート３の間には繊維シート５が設けられ、繊維シート５は吸収体４の前側端よりも前側に延在し、かつ吸収体４の後側端よりも後側に延在していることが好ましい。これにより、吸収性物品１の吸収体４が存在しない前後端部における剛性を高めることができる。そのため、吸収性物品１を装着する際に、吸収性物品１の前後端部の折れ曲がりを防ぎ、吸収性物品１を安定して着用者の肌に取り付けることができる。吸収性物品１の前後端部の剛性をより高める点から、繊維シート５は、トップシート２とバックシート３よりも目付が大きいことが好ましい。繊維シート５の目付は、例えば３０ｇ／ｍ²〜６０ｇ／ｍ²とすることが好ましい。 A fiber sheet 5 is provided between the absorber 4 and the back sheet 3 from the viewpoint of enhancing the shape retention of the absorbent article 1, and the fiber sheet 5 extends to the front side of the front end of the absorber 4 and extends to the front side. It preferably extends posteriorly of the posterior end of the absorber 4. As a result, the rigidity of the absorbent article 1 at the front and rear ends where the absorber 4 does not exist can be increased. Therefore, when the absorbent article 1 is attached, the front and rear ends of the absorbent article 1 can be prevented from bending, and the absorbent article 1 can be stably attached to the wearer's skin. The fiber sheet 5 preferably has a larger basis weight than the top sheet 2 and the back sheet 3 from the viewpoint of further increasing the rigidity of the front and rear ends of the absorbent article 1. Basis weight of the fiber sheet 5 is preferably, for example, ^{^{30g / m 2 ~60g / m 2}} .

繊維シート５は、粘着部９Ｆよりも前側に延在し、粘着部９Ｂよりも後側に延在していることが好ましい。特に、粘着部９が吸収体４の前側端または後側端と重なって設けられるか、それよりも前後方向ｙの外方に設けられる場合は、そのように繊維シート５が設けられることが好ましい。これにより、吸収性物品１が粘着部９の前側端または後側端に沿って折れ曲がりにくくなり、吸収性物品１を装着する際に、粘着部９を着用者の肌に安定して取り付けやすくなる。 It is preferable that the fiber sheet 5 extends to the front side of the adhesive portion 9F and extends to the posterior side of the adhesive portion 9B. In particular, when the adhesive portion 9 is provided so as to overlap the front end or the rear end of the absorber 4 or is provided outside in the front-rear direction y, it is preferable that the fiber sheet 5 is provided as such. .. As a result, the absorbent article 1 is less likely to bend along the front end or the posterior end of the adhesive portion 9, and when the absorbent article 1 is attached, the adhesive portion 9 can be stably attached to the wearer's skin. ..
