Description

本発明は、止着テープ型、パンツ型の使い捨ておむつ、あるいは、生理用ナプキン等の使い捨て吸収性物品に関し、特に好適には、吸収パッド型使い捨て紙おむつを重ねて併用する形式の使い捨ておむつに適用することができる。   The present invention relates to a disposable absorbent article such as a fastening tape type, a pants-type disposable diaper, or a sanitary napkin, and particularly preferably applied to a disposable diaper of a type in which an absorbent pad type disposable paper diaper is used in combination. be able to.

近年、使い捨て紙おむつ、生理用ナプキン等の使い捨て吸収性物品は、防漏ギャザー、立体ギャザー、二重カフス等の防漏手段を備えたものが多く使用されている。そして、また、この種の防漏手段を備えた使い捨て紙おむつにおいて、体液の量が多く、より大きな吸収力を必要とする場合、特に、大人用のおむつとして使用する場合は、吸収性、経済性の観点から、吸収体の上にさらに補助的に、両側にバリヤーカフスを有しない吸収パッド、あるいは両側にバリヤーカフスを有するパッド型おむつを重ねて使用する利用がなされている。なお、以下において断りのない限り、紙おむつの本体の使用面側に重ねる吸収パッドやパッド型おむつを「補助パッド」と言う。
しかしながら、着用時において製品紙おむつ本体の使用面に補助パッドを重ねる場合、重ねる補助パッドの吸収体の厚みが加わり、また紙おむつ本体の吸収体に対して補助パッドの吸収体が二重になることが原因で全体としての剛性が高まることにより、バリヤーカフスの自由変形が阻害され、バリヤーカフスの起立幅をいくら大きくしても、肌に密着し難くその機能が十分に発揮しないことが知見された。
もっとも、ギャザーの伸縮力を強くすることにより肌への密着性を担保することが想定されるが、必要以上の収縮力は着用者に圧迫感を感じさせ、装着感が著しく劣るものとなるとの問題がある。 In recent years, disposable absorbent articles such as disposable paper diapers and sanitary napkins are often used which are equipped with leak-proof means such as leak-proof gathers, three-dimensional gathers, and double cuffs. And in disposable paper diapers equipped with this kind of leak-proof means, when the amount of body fluid is large and a greater absorbency is required, especially when used as a diaper for adults, it is absorbent and economical. In view of the above, there is an additional use in which an absorbent pad that does not have barrier cuffs on both sides or a pad-type diaper that has barrier cuffs on both sides is used in an auxiliary manner on the absorbent body. In the following, unless otherwise noted, an absorbent pad or a pad-type diaper that is stacked on the use surface side of the main body of the paper diaper is referred to as an “auxiliary pad”.
However, when the auxiliary pad is stacked on the use surface of the product paper diaper body when worn, the thickness of the absorbent body of the auxiliary pad to be added may be added, and the absorbent body of the auxiliary pad may be doubled with respect to the absorbent body of the paper diaper body. It has been found that, due to the increase in rigidity as a whole, free deformation of the barrier cuff is inhibited, and no matter how large the standing width of the barrier cuff is, it does not adhere well to the skin and does not perform its function sufficiently.
However, it is assumed that adhesion to the skin will be ensured by increasing the elastic force of the gathers, but the shrinkage force more than necessary will cause the wearer to feel a sense of pressure, and the wearing feeling will be significantly inferior. There's a problem.

そこで、本発明の課題は、単独で用いても、補助パッドを重ねて用いても、横漏れ防止効果が高く、しかも、装着感に優れる使い捨て吸収性物品を提供することにある。   Therefore, an object of the present invention is to provide a disposable absorbent article that has a high side leakage prevention effect and is excellent in wearing feeling, whether used alone or in an overlapping manner.

上記課題を解決した本発明は次記のとおりである。
使用状態において使用面側において自由起立する脚周り用バリヤーカフスを有する使い捨て吸収性物品において、
前記バリヤーカフスは、自由端をなす遠位縁および基端をなす近位縁を有し、
前記バリヤーカフスにおける遠位縁および起立領域内の近位縁の近傍に弾性伸縮部材が伸長下でそれぞれ固定され、
非伸長自由下にてバリヤーカフス部分を側方から見て、バリヤーカフスが扇紙形状に起立し、着用者の装着時には、バリヤーカフスが遠位縁及び近位縁のうち遠位縁において前後側が弱くこれよりも中心側が強く脚周りに接触するとともに、遠位縁及び近位縁のうち遠位縁において前後側が小さくこれよりも中心側が大きく起立して脚周りに接触するようになっている、
ことを特徴とする使い捨て吸収性物品。 The present invention that has solved the above problems is as follows.
In a disposable absorbent article having a barrier cuff for the leg circumference that stands up freely on the use surface side in use,
The barrier cuff has a distal edge forming a free end and a proximal edge forming a proximal end,
Elastic stretch members are respectively fixed under extension near the distal edge in the barrier cuff and the proximal edge in the standing region,
When viewed from the side, the barrier cuff stands up in a fan paper shape under non-extension freedom, and when worn by the wearer, the barrier cuff is located at the distal edge and the distal edge of the distal edge and the proximal edge. It is weaker and the center side is more strongly in contact with the legs, and the front and rear sides of the distal edge and the proximal edge are smaller on the distal edge and the center side is more upright to contact the legs.
A disposable absorbent article characterized by that.

本発明によれば、単独で用いても、補助パッドを重ねて用いても、横漏れ防止効果が高く、しかも、装着感に優れたものとなる。   According to the present invention, whether it is used alone or used with overlapping auxiliary pads, the effect of preventing side leakage is high, and the wearing feeling is excellent.

以下本発明を、図面に示す実施の形態によってさらに詳説する。なお、本発明の使い捨て吸収性物品としては、紙おむつのほか、ナプキンなどにも適用が可能である。また、特に、パンツ型紙おむつにも適用が可能であることは明らかであるので、以下においてはテープ式の特に大人用の補助パッド併用型使い捨て紙おむつのみについて説明し、パンツ型紙おむつへの適用例を省略する。   Hereinafter, the present invention will be described in more detail with reference to embodiments shown in the drawings. The disposable absorbent article of the present invention can be applied to napkins and the like in addition to disposable diapers. In particular, since it is clear that the present invention can also be applied to pants-type paper diapers, only the tape-type disposable pad-type disposable diapers for adults in particular will be described below, and application examples to pants-type paper diapers will be described. Omitted.

図１及び図２に示す紙おむつでは、不織布や多孔フィルムなどからなる長方形などの形状の透液性表面シート１とポリエチレンやポリラミ不織布、ミクロボイドを形成して蒸気は透過するが液は透過させない形態等からなる砂時計形状の不透液性裏面シート２との間に、綿状パルプ等からなる、たとえば長方形や砂時計形状など適宜形状のある程度剛性を有する吸収体３が介在されている。この吸収体３には高分子吸収性ポリマーを添加できる。吸収体３は吸収用の上下ティッシュペーパー３Ａ，３Ｂで被覆することができ、吸収要素を構成している。   In the disposable diaper shown in FIG. 1 and FIG. 2, a liquid-permeable surface sheet 1 having a shape such as a rectangle made of a nonwoven fabric or a porous film, a polyethylene or polylaminated nonwoven fabric, a microvoid is formed, and vapor is transmitted but liquid is not transmitted. Between the hourglass-shaped liquid-impervious back sheet 2 made of the above, an absorbent body 3 made of cotton-like pulp or the like and having a certain degree of rigidity such as a rectangular shape or an hourglass shape is interposed. A polymer-absorbing polymer can be added to the absorber 3. The absorbent body 3 can be covered with upper and lower tissue papers 3A and 3B for absorption, and constitutes an absorbent element.

透液性表面シート１は吸収要素より幅広の長方形をなし、吸収要素の側縁より若干外方に延在し、不透液性裏面シート２とホットメルト接着剤などにより固着されている（この固着部分を含めて断面における固着部分を＊で示す）。   The liquid-permeable top sheet 1 has a rectangular shape wider than the absorbent element, extends slightly outward from the side edge of the absorbent element, and is fixed to the liquid-impervious back sheet 2 by a hot melt adhesive or the like (this (In the cross section including the fixing portion, the fixing portion is indicated by *).

紙おむつの両側部には、使用面側に突出して自由起立する脚周り用バリヤーカフスＢが形成され、このバリヤーカフスＢは、実質的に幅方向に連続したバリヤーシート４と、適宜数の実施の形態では２本の接触用弾性伸縮部材（遠位縁近傍の弾性伸縮部材）５Ａ，５Ａ、及び適宜数の実施の形態では３本の起立用弾性伸縮部材（近位縁近傍の弾性伸縮部材）５Ｂ，５Ｂ，５Ｂとにより構成されている。これらの弾性伸縮部材はたとえば糸ゴムや帯状ゴムなどにより構成できる。６は背側漏れ防止用フラップで、遠位縁部に接触用弾性伸縮部材７Ａを、自由部の基部に押圧用弾性伸縮部材７Ｂを備える。８は止着テープである。   On both sides of the paper diaper, there are formed leg cuffs B for leg surroundings that protrude freely on the use surface side, and the barrier cuffs B are substantially continuous with the barrier sheet 4 in the width direction, and an appropriate number of implementations. In the embodiment, two elastic elastic members for contact (elastic elastic members near the distal edge) 5A, 5A, and in an appropriate number of embodiments, three elastic elastic members for standing up (elastic elastic members near the proximal edge) 5B, 5B, 5B. These elastic elastic members can be made of, for example, thread rubber or belt rubber. Reference numeral 6 denotes a back-side leakage prevention flap, which includes a contact elastic expansion / contraction member 7A at the distal edge and a pressing elastic expansion / contraction member 7B at the base of the free portion. 8 is a fastening tape.

さらに、バリヤーカフスＢは、バリヤーシート４を内面側を短くして段違いに内折りして２重に形成され、接触用弾性伸縮部材５Ａ，５Ａ、及び起立用弾性伸縮部材５Ｂ，５Ｂ，５Ｂをホットメルト接着剤などにより固着した状態で包んでいる。実施の形態では、折り目が遠位縁Ｅ１を構成している。   Further, the barrier cuff B is formed by double folding the barrier sheet 4 by shortening the inner surface side inwardly, and forming the elastic elastic members 5A and 5A for contact and the elastic elastic members 5B, 5B and 5B for standing. Wrapped in a hot-melt adhesive. In the embodiment, the fold line constitutes the distal edge E1.

二重のバリヤーシート４の内層の幅方向外方部分は、透液性表面シート１の端部に固着始端をもって不透液性裏面シート２表面に、バリヤーシート４の外層の外側部分も同じく不透液性裏面シート２表面に、それぞれホットメルト接着剤などにより固着されている。   The outer part in the width direction of the inner layer of the double barrier sheet 4 is fixed to the surface of the liquid-impervious back sheet 2 with the sticking start edge at the end of the liquid-permeable surface sheet 1, and the outer part of the outer layer of the barrier sheet 4 is also the same. Each is fixed to the surface of the liquid-permeable back sheet 2 with a hot melt adhesive or the like.

その結果、二重のバリヤーシート４の内層の、透液性表面シート１への固着始端は、バリヤーカフスＢの近位縁Ｅ２を形成している。脚周りにおいて、この近位縁Ｅ２より内側は、製品本体に固定されていない自由に起立する起立領域Ｚである。   As a result, the starting edge of the inner layer of the double barrier sheet 4 to the liquid-permeable surface sheet 1 forms the proximal edge E2 of the barrier cuff B. Around the leg, the inner side of the proximal edge E2 is a free-standing standing area Z that is not fixed to the product body.

バリヤーカフスＢの脚周りにおける起立領域Ｚの製品幅方向の長さＬは１０ｍｍ以上、特に紙おむつの場合には３０〜８０ｍｍとするのが望ましい。   The length L in the product width direction of the standing region Z around the leg of the barrier cuff B is preferably 10 mm or more, particularly 30 to 80 mm in the case of a paper diaper.

他方、図１に示すように、長手方向端部におけるバリヤーシート４とこれを除く製品との固定関係について着目すると、起立領域Ｚのバリヤーシート４の長手方向両端部が製品の使用面側に対して、具体的に実施の形態では背側においては背側漏れ防止用フラップ６及び透液性表面シート１上にホットメルト接着剤により固定され、腹側においてはフラップが設けられていないので、透液性表面シート１上に直接ホットメルト接着剤により固定されている。   On the other hand, as shown in FIG. 1, when attention is paid to the fixing relationship between the barrier sheet 4 and the product excluding the barrier sheet 4 at the end in the longitudinal direction, both ends in the longitudinal direction of the barrier sheet 4 in the standing region Z are on the use surface side of the product. Specifically, in the embodiment, the back side is fixed on the back side leakage preventing flap 6 and the liquid-permeable surface sheet 1 by a hot melt adhesive, and the abdomen side is not provided with a flap. It is directly fixed on the liquid surface sheet 1 by a hot melt adhesive.

そして、特に図１に網点でホットメルト接着剤の固定部位Ｆを示すように、腹側において、起立遠位縁Ｅ１側におけるバリヤーシート４の固定開始位置ｆ１が、起立近位縁Ｅ２側の固定開始位置ｆ２より、製品の長手方向の端縁側に偏位している。背側におけるバリヤーシート４の固定開始位置ｆ３は、製品の長手方向の端縁に対して平行であり偏位関係にはない。   In particular, as shown in FIG. 1, the fixing point F of the hot melt adhesive is indicated by a halftone dot, and on the abdominal side, the fixing start position f1 of the barrier sheet 4 on the standing distal edge E1 side is on the standing proximal edge E2 side. It deviates from the fixing start position f2 toward the end edge in the longitudinal direction of the product. The fixing start position f3 of the barrier sheet 4 on the back side is parallel to the edge in the longitudinal direction of the product and is not displaced.

かかる関係の下で、バリヤーカフスＢの起立遠位縁Ｅ１近傍に接触用弾性伸縮部材５Ａ，５Ａが配置され、バリヤーカフスＢの起立領域Ｚ内の起立近位縁Ｅ２近傍側に起立用弾性伸縮部材５Ｂ，５Ｂ，５Ｂが配置されている。   Under such a relationship, the elastic contact members 5A and 5A are disposed in the vicinity of the standing distal edge E1 of the barrier cuff B, and the elastic stretching member for standing is disposed in the vicinity of the standing proximal edge E2 in the standing region Z of the barrier cuff B. Members 5B, 5B, 5B are arranged.

そして、接触用弾性伸縮部材５Ａ，５Ａについては、ほぼｆ１とｆ３との長さ部分が、起立用弾性伸縮部材５Ｂ，５Ｂ，５Ｂについては、ほぼｆ２とｆ３との長さ部分が収縮するように、伸長下でバリヤーシート４にホットメルト接着剤により固定されている。したがって、接触用弾性伸縮部材５Ａ，５Ａの有効伸縮長さより、起立用弾性伸縮部材５Ｂ，５Ｂ，５Ｂの有効伸縮長さが短いように構成されている。   For the elastic elastic members 5A and 5A for contact, the length portion between f1 and f3 is contracted, and for the elastic elastic members 5B, 5B and 5B for standing up, the length portion between f2 and f3 is contracted. Further, it is fixed to the barrier sheet 4 with a hot melt adhesive under elongation. Therefore, the effective elastic length of the standing elastic elastic members 5B, 5B, 5B is shorter than the effective elastic length of the contact elastic elastic members 5A, 5A.

図２の上段は、紙おむつを長手方向に伸長した状態であるが、装着時には、図２の下段に図示するように、紙おむつが前後方向に舟形に体に装着されるので、そして各弾性伸縮部材５Ａ，…及び５Ｂ…の収縮力が作用するので、製品の前後端は図２の上段と同様の形態を保持したまま、脚周りでは、各弾性伸縮部材５Ａ，…及び５Ｂ…の収縮力によりバリヤーカフスＢが起立する。   The upper stage of FIG. 2 is a state in which the paper diaper is elongated in the longitudinal direction. However, as shown in the lower stage of FIG. 2, the paper diaper is attached to the body in a boat shape in the front-rear direction. 5A,... And 5B... Acts, so that the front and rear ends of the product retain the same form as the upper stage of FIG. 2 and the elastic force members 5A,. Barrier cuffs B stand up.

このとき、サイドフラップ部を変形させ持ち上げ、また若干吸収体３も変形させつつ持ち上げ、深いポケット空間を形成する。   At this time, the side flap portion is deformed and lifted, and the absorber 3 is also lifted while being slightly deformed to form a deep pocket space.

しかも、この持ち上げ状態で、起立用弾性伸縮部材５Ｂ，５Ｂ，５Ｂの強い収縮力がバリヤーカフスＢ自体に作用するから、バリヤーカフスＢがほぼ垂直に起立するように作用する。同時に、接触用弾性伸縮部材５Ａ，５Ａは弱いながらその収縮力によりバリヤーカフスＢを起立させる。しかるに、接触用弾性伸縮部材５Ａ，５Ａの収縮力は弱いとしても、起立用弾性伸縮部材５Ｂ，５Ｂ，５ＢによるバリヤーカフスＢの起立力が大きいので、全体としてバリヤーカフスＢの起立が確実に確保される。そして、接触用弾性伸縮部材５Ａ，５Ａの収縮力は強くないので、着用者の肌への過度の圧接がない。   In addition, in this lifted state, the strong contraction force of the elastic elastic members 5B, 5B, 5B for standing acts on the barrier cuff B itself, so that the barrier cuff B acts so as to stand almost vertically. At the same time, the barrier elastic cuffs 5A and 5A are weak, but the barrier cuffs B are raised by the contraction force. However, even if the contracting force of the elastic elastic members 5A and 5A for contact is weak, the rising force of the barrier cuff B by the elastic elastic members 5B, 5B and 5B for standing is large, so that the barrier cuff B is reliably secured as a whole. Is done. And since the contractive force of the elastic elastic members 5A, 5A for contact is not strong, there is no excessive pressure contact with the wearer's skin.

さらに図５によって概念的なバリヤーカフスの起立態様を補足的に説明すると、接触用弾性伸縮部材５Ａ，５Ａの有効伸長長さが長く、その収縮力は弱いのに対して、起立用弾性伸縮部材５Ｂ，５Ｂ，５Ｂの有効伸長長さが短く、その収縮力は強いので、長手方向中心に向かう収縮力が近位縁側が遠位縁側より大きいから、非伸長自由下に置いた紙おむつのバリヤーカフス部分を側方から見ると、（Ａ）図のように、あたかも扇紙形状に起立するようになる。その結果、着用者の装着時には（ Ｂ）図のように、遠位縁において前後側が弱く中心側が比較的強く脚周りに接触するので、他方で遠位縁において前後側が小さく中心側が比較的大きく起立して脚周りに接触するので、特に遠位縁の中心側から液漏れが生じ易いことに適確に対処できる。   Further, FIG. 5 supplementarily explains the standing manner of the barrier cuff. The elastic elastic members 5A and 5A for contact use have a long effective extension length and their contraction force is weak, whereas the elastic elastic members for standing use. Since the effective extension length of 5B, 5B, and 5B is short and the contraction force is strong, the contraction force toward the longitudinal center is larger at the proximal edge side than at the distal edge side. When the part is viewed from the side, as shown in FIG. As a result, when the wearer wears, the front and rear sides are weak at the distal edge and the center side is relatively strong and contacts the leg, as shown in Fig. B. On the other hand, the front and rear sides are small at the distal edge and the center side is relatively large. And since it contacts the circumference | surroundings of a leg, it can respond appropriately that it is easy to produce a liquid leak especially from the center side of a distal edge.

本発明の形態によると、バリヤーカフスＢの起立が確実に確保されるので、図６に示すように、補助パッド１０を使用面側に重ねて配設したとしても、バリヤーカフスＢの起立が確保され、これが寝たり反り返ったりすることなく、補助パッド１０を確実に包み込むことができる。   According to the embodiment of the present invention, since the rising of the barrier cuff B is reliably ensured, as shown in FIG. 6, even if the auxiliary pad 10 is disposed on the use surface side, the rising of the barrier cuff B is ensured. Thus, the auxiliary pad 10 can be reliably wrapped without sleeping or warping.

他方、図１に網点でホットメルト接着剤の固定部位Ｆが示されているように、腹側においては、バリヤーカフスＢの端部の固定態様を工夫してある。すなわち、図４に示すように、端部側の４Ａ部では長手方向端部であるのでバリヤーカフスＢの遠位縁の起立高が小さく、かつバリヤーカフスＢの基部は固定部位Ｆの存在により拘束されている。これに対して、中央側の４Ｂ部では、固定部位Ｆの存在がないから、起立用弾性伸縮部材５Ｂ，５Ｂ，５ＢによりバリヤーカフスＢが高く起立しようとする。しかるに、端部側の４Ａ部においてバリヤーカフスＢの遠位縁の起立高が小さいので、中央側の４Ｂ部におけるバリヤーカフスＢの遠位縁に対して、押え付けるように作用し、その結果、図４の下段に示すように、バリヤーカフスＢは、その高さ方向中間部を外方に膨らませながら起立するようになる。これにより、バリヤーカフスＢのポケットが形成され、補助パッド１０の包み込みも確実なものとなる。   On the other hand, as shown in FIG. 1, the fixing portion F of the hot melt adhesive is indicated by a halftone dot, and the fixing manner of the end portion of the barrier cuff B is devised on the ventral side. That is, as shown in FIG. 4, the 4A portion on the end side is a longitudinal end portion, so that the standing height of the distal edge of the barrier cuff B is small, and the base portion of the barrier cuff B is constrained by the presence of the fixing portion F. Has been. On the other hand, since the fixed portion F does not exist in the central portion 4B, the barrier cuff B tends to rise with the standing elastic elastic members 5B, 5B, 5B. However, since the standing height of the distal edge of the barrier cuff B is small at the end side 4A portion, it acts to press against the distal edge of the barrier cuff B at the central side 4B. As shown in the lower part of FIG. 4, the barrier cuff B comes to stand while inflating its intermediate portion in the height direction outward. Thereby, the pocket of the barrier cuff B is formed, and the auxiliary pad 10 can be securely wrapped.

ところで、バリヤーシートの材料としては、通気性及び液不透過性のプラスチックフィルムやシリコン処理などによる撥水性の不織布を利用できる。また、図７に示すように、液の透過を確実に防止するために、撥水性の不織布または撥水性を有しない不織布にプラスチックフィルム等からなる防水性シート７Ｃを介在させるとよい。好ましい不織布としてはメルトブローン方式で製造したポリプロピレン不織布がより好適である。坪量として５〜３０ｇ／ｍ2の厚さのシートを袋綴じしたような形態に接着し、袋状の端縁を自由端とする。弾性部材としては、天然ゴム、合成ゴム、ポリウレタン等からなる糸状体複数本として、または帯状体とすることができる。実施の形態では，５Ｂ，５Ｂの強い収縮力がバリヤーカフスＢ自体に作用するから、バリヤーカフスＢがほぼ垂直に起立するように作用する。同時に、接触用弾性伸縮部材５Ａとして５６０デニールウレタン糸２本を２８０％伸長状態で、長さ方向的６５０ｍｍに渡って設置し、起立用弾性伸縮部材５Ｂとして５６０デニールウレタン糸３本を約５ｍｍ間隔で２８０％伸長状態で、長さ方向的４２０ｍｍに渡って設置した。 By the way, as a material for the barrier sheet, a breathable and liquid-impermeable plastic film, a water-repellent nonwoven fabric by silicon treatment or the like can be used. Moreover, as shown in FIG. 7, in order to prevent permeation | transmission of a liquid reliably, it is good to interpose the waterproof sheet 7C which consists of a plastic film etc. in the water-repellent nonwoven fabric or the nonwoven fabric which does not have water repellency. As a preferable non-woven fabric, a polypropylene non-woven fabric manufactured by a melt blown method is more suitable. A sheet having a thickness of 5 to 30 g / m 2 as a basis weight is adhered to a bag-bound form, and a bag-like edge is used as a free end. As the elastic member, a plurality of filamentous bodies made of natural rubber, synthetic rubber, polyurethane, or the like, or a strip-shaped body can be used. In the embodiment, since the strong contraction force of 5B and 5B acts on the barrier cuff B itself, the barrier cuff B acts so as to stand substantially vertically. At the same time, two 560 denier urethane yarns are stretched over 650 mm in the lengthwise direction as 280% stretched elastic contact members 5A for contact, and three 560 denier urethane yarns are spaced approximately 5mm apart as standing elastic stretch members 5B. And 280% stretched over a length direction of 420 mm.

テープ式おむつの装着時、バリヤーカフスＢにおける接触用弾性伸縮部材５Ａ及び起立用弾性伸縮部材５Ｂの伸長率はそれぞれ６０〜１５０％変化するが、その時の伸長応力は、接触用弾性伸縮部材５Ａが０．２９〜１Ｎ好ましくは０．３９〜０．９０Ｎ、起立用弾性伸縮部材５Ｂが０．３９〜１．５０Ｎ好ましくは０．４９〜１．３８Ｎであれば、着用者は圧迫感を感じることなくまたレッグ周囲部に隙間を生じることがなく、優れた漏れ防止性能を発揮することができる。上述した実施の形態では、接触用弾性伸縮部材５Ａの６０〜１５０％伸長率時の応力は０．３９〜０．９０Ｎ、起立用弾性伸縮部材５Ｂの６０〜１５０％伸長率時の応力が０．４９〜１．３８Ｎとなっている。   When the tape-type diaper is mounted, the elongation rate of the elastic elastic member for contact 5A and the elastic elastic member for standing 5B in the barrier cuff B varies by 60 to 150%. The elongation stress at that time is that of the elastic elastic member for contact 5A. If the elastic elastic member 5B for standing is 0.39 to 1.50N, preferably 0.49 to 1.38N, the wearer feels a feeling of pressure. In addition, no gap is formed around the leg, and excellent leakage prevention performance can be exhibited. In the above-described embodiment, the stress at the stretch rate of 60 to 150% of the elastic elastic member 5A for contact is 0.39 to 0.90 N, and the stress at the stretch rate of 60 to 150% of the elastic stretch member 5B for standing is 0. .49 to 1.38N.
