前記吸収体の嵩高部は、パルプを立体形状に積繊することにより形成されるか、或いは下層吸収体の上面に上層吸収体を重ねることにより形成されるが、ある程度大きな嵩高部を形成するには、大量のパルプや化繊を必要とするため、資材コストが上昇するとともに、高密度で積繊するために特殊な積繊機が必要になるなどの問題があった。   The bulky portion of the absorbent body is formed by stacking pulp into a three-dimensional shape, or is formed by overlapping the upper layer absorbent body on the upper surface of the lower layer absorbent body. However, since a large amount of pulp and synthetic fiber are required, the material cost is increased, and a special fiber stacker is necessary for stacking at high density.

また、身体に対する密着度を嵩高部の高さを上げることにより実現せんとする場合には、高密度で積繊されたパルプの剛性が高くなり、装着時に違和感や圧迫感を伴うようになるなどの問題があった。   In addition, when the degree of close contact with the body is increased by increasing the height of the bulky part, the stiffness of the pulp piled up at a high density becomes high, and there is a sense of incongruity or pressure when worn. There was a problem.

そこで本発明の主たる課題は、吸収体を立体形状(隆起形状)に変形させることにより股部凹凸への密着性を向上させた吸収性物品を提供することにある。   Then, the main subject of this invention is providing the absorbent article which improved the adhesiveness to a crotch | groove unevenness | corrugation by deform | transforming an absorber into a solid | 3D shape (raised shape).

The absorber comprises a lower layer absorber and one or more upper layer absorbers disposed on the body side surface of the lower layer absorber and having a smaller area than the lower layer absorber,
The lower layer absorber is divided into a front absorber region, a crotch absorber region, and a rear absorber region, and is easily deformable in the transverse direction along the longitudinal direction at or near the longitudinal center line position of the absorbent article. And the crotch lower absorbent region has a narrowest portion whose width is narrower than the front absorbent region and the rear absorbent region, and both side portions of the narrowest portion. substantially longitudinal direction or along the absorbent article, comprising one or more ridges for resilient and elastic members arranged in a bulging curve shape in the longitudinal direction of the center line side of the absorbent article in a plan view Rutotomoni, it said raised Among the elastic elastic members for use, a plurality of raised elastic elastic members are arranged so that the start and end points overlap the front absorber region and the rear absorber region, and the upper absorber is a flexible part of the lower absorber Arranged to straddle
In the mounted state, the both sides of the front absorber region and both sides of the rear absorber region are drawn toward the crotch side by the stretching force of the elastic elastic member for bulging, so that the crotch absorber region has a longitudinal section. It is characterized in that it is raised on the body side and is mountain-folded in a cross section in the transverse direction, raised on the body surface side, and the upper absorbent body superimposed on the upper surface of this raised portion is in close contact with the body An absorbent article is provided.

上記請求項1記載の本発明においては、吸収体を下層吸収体と上層吸収体とから構成し、前記下層吸収体において、吸収性物品の長手方向中心線位置又はその近傍に長手方向に沿って横断方向に易変形性の可撓部分を有するとともに、前記股下部吸収体領域は幅寸法が前記前部吸収体領域及び後部吸収体領域よりも幅狭とされる最狭部を有し、該最狭部の両側部に吸収性物品の略長手方向に沿うか、平面視で吸収性物品の長手方向中心線側に膨出する曲線形状で配置された1又は複数の隆起用弾性伸縮部材を備えるとともに、前記隆起用弾性伸縮部材の内、複数本の隆起用弾性伸縮部材の始終端は前記前部吸収体領域、後部吸収体領域に重なるように配置され、前記上層吸収体は前記下層吸収体の可撓部分に跨るように配設され、装着状態で、前記隆起用弾性伸縮部材による伸縮力によって前部吸収体領域の両側部と、後部吸収体領域の両側部とが股下側に引き寄せられることにより、股下部吸収体領域が長手方向断面で身体側に隆起するとともに、横断方向断面で山折り状態となって身体面側に隆起し、この隆起部分の上面に重ねられた前記上層吸収体を身体に密着させるようにしたIn the present invention according to claim 1, the absorber is composed of a lower layer absorber and an upper layer absorber, and in the lower layer absorber, along the longitudinal direction at or near the longitudinal center line position of the absorbent article. The crotch lower part absorber region has a narrowest part whose width dimension is narrower than the front part absorber region and the rear part absorber region, and has a flexible part that is easily deformable in the transverse direction. One or a plurality of raised elastic stretch members arranged in a curved shape that extends substantially along the longitudinal direction of the absorbent article on both sides of the narrowest part or bulges toward the longitudinal center line of the absorbent article in plan view comprising Rutotomoni, among the bumps for resilient and elastic members, the starting and end of the plurality of raised elastic stretchable member is disposed so as to overlap said front absorber region, the rear absorber region, the upper layer absorber the lower It is arranged so as to extend the flexible portion of the absorbent body, in the mounted state The both sides of the front absorber region and both sides of the rear absorber region are drawn toward the crotch side by the stretching force of the elastic elastic member for raising, so that the crotch absorber region is moved to the body side in the longitudinal section. In addition to being raised, the cross section in the transverse direction is in a mountain-folded state and raised on the body surface side, and the upper absorbent body superimposed on the upper surface of the raised portion is brought into close contact with the body .

従って、前記下層吸収体の中間部分(股下部分)は、前記最狭部の両側に配設された隆起用弾性伸縮部材の収縮力により、身体側に隆起するように変形するため、上面に配設された上層吸収体を身体に押し付けるようにしながら装着することができる。この方法であれば、パルプ剛性を上げることなく、身体への密着が図れるようになるため、従来のように装着時に違和感や圧迫感を伴うことがない。 Therefore, the intermediate portion (inseam portion) of the lower layer absorbent body is deformed so as to rise to the body side by the contraction force of the elastic elastic member for raising disposed on both sides of the narrowest portion, and is therefore arranged on the upper surface. It can be worn while pressing the upper absorbent body provided against the body. With this method, it is possible to achieve close contact with the body without increasing the pulp rigidity, so that there is no sense of incongruity or pressure at the time of wearing.

請求項2に係る本発明として、前記可撓部分は、前記下層吸収体が長手方向中心線位置又はその近傍で左右に分割されることにより形成されている請求項1記載の吸収性物品が提供される。   According to a second aspect of the present invention, there is provided the absorbent article according to the first aspect, wherein the flexible portion is formed by dividing the lower layer absorbent body into left and right at or near the longitudinal center line position. Is done.

上記請求項2記載の本発明では、前記可撓部分を、前記下層吸収体が長手方向中心線位置又はその近傍で左右に分割されることにより形成するものである。すなわち、下層吸収体を左右に分割した構造とすることにより、吸収体が存在しない境界を長手方向に沿う可撓部分とすることができる。   In the present invention according to the second aspect, the flexible portion is formed by dividing the lower layer absorbent body into left and right portions at or near the longitudinal center line position. That is, by making the lower layer absorbent body into a left and right structure, the boundary where the absorbent body does not exist can be a flexible portion along the longitudinal direction.

請求項3に係る本発明として、前記可撓部分は、前記下層吸収体の長手方向中心線位置又はその近傍に、長手方向に沿って不連続のスリットを設けることにより形成されている請求項1記載の吸収性物品が提供される。   As the present invention according to claim 3, the flexible portion is formed by providing a discontinuous slit along the longitudinal direction at or near the longitudinal center line position of the lower layer absorber. The absorbent article described is provided.

上記請求項3記載の発明においては、前記可撓部分を、前記下層吸収体の長手方向中心線位置又はその近傍に、長手方向に沿って不連続のスリットを設けることにより形成する。上記請求項2記載の発明のように、完全に分離した構造としなくても、中央に長手方向に沿って不連続のスリットを形成することでも、他の部分より低剛性化できるようになり、可撓部分として機能させることが可能となる。前記不連続スリットの形成態様としては、例えば下層吸収体の上部及び下部以外を除いて長手方向に沿って1本のスリットを形成する態様と、下層吸収体の長手方向に沿って途中で不連続部を有するように複数本のスリットを形成する場合とを含むものである。前者のように1本のスリットを形成する場合は、長手方向に沿って全体が湾曲形状で変形し易い傾向を示すのに対して、後者のように複数本のスリットを形成した場合には、途中の不連続部が他より高剛性部となり多曲点状に角折れするように身体に沿って変形し易い傾向を示す。従って、後者の態様で身体形状を考慮して曲点としたい部分に前記スリット不連続点を設けることにより身体形状に沿って変形し易いように制御することが可能である。   In the invention of claim 3, the flexible portion is formed by providing a discontinuous slit along the longitudinal direction at or near the longitudinal center line of the lower layer absorber. Even if it is not a completely separated structure as in the invention of claim 2 above, even if a discontinuous slit is formed in the center along the longitudinal direction, the rigidity can be reduced from other parts. It becomes possible to function as a flexible part. For example, the discontinuous slit may be formed in a manner in which one slit is formed along the longitudinal direction except for the upper and lower portions of the lower layer absorber, and discontinuous along the longitudinal direction of the lower layer absorber. And a case where a plurality of slits are formed so as to have a portion. When forming a single slit as in the former, the whole tends to be deformed with a curved shape along the longitudinal direction, whereas when forming a plurality of slits as in the latter, The discontinuous part in the middle becomes a higher rigidity part than others, and it tends to be easily deformed along the body so as to be bent into a multi-curved point. Therefore, in the latter mode, it is possible to control so as to be easily deformed along the body shape by providing the slit discontinuity point at a portion where the bending point is desired in consideration of the body shape.

請求項4に係る本発明として、前記上層吸収体の配設領域内に対応する下層吸収体部分に、吸収体の存在しないポケット空間を形成してある請求項1〜3いずれかに記載の吸収性物品が提供される。   The absorption according to any one of claims 1 to 3, wherein a pocket space in which no absorber exists is formed in the lower layer absorber corresponding to the arrangement region of the upper absorber as the present invention according to claim 4. A sex article is provided.

上記請求項4記載の発明においては、前記上層吸収体の配設領域内に対応する下層吸収体部分に、吸収体の存在しないポケット空間を形成する。従って、装着状態で下層吸収体のポケット空間が、両側の下層吸収体部分で押し潰されるように変形することによって、前記上層吸収体を身体側に隆起(押圧)させることができる。   In the invention described in claim 4, a pocket space in which no absorber is present is formed in the lower layer absorber corresponding to the arrangement region of the upper layer absorber. Therefore, the upper layer absorbent body can be raised (pressed) to the body side by deforming the pocket space of the lower layer absorbent body so as to be crushed by the lower layer absorbent parts on both sides in the mounted state.

請求項5に係る本発明として、前記吸収性物品の前部及び/又は後部において、前後端縁中央から吸収性物品の略長手方向に沿ってスリットを形成してある請求項1〜4いずれかに記載の吸収性物品が提供される。   As this invention which concerns on Claim 5, in the front part and / or rear part of the said absorbent article, the slit is formed along the substantially longitudinal direction of an absorbent article from the front-and-rear edge center. An absorbent article as described in 1 above is provided.

上記請求項5記載の発明においては、前記吸収性物品の前部及び/又は後部において、前後端縁中央から吸収性物品の略長手方向に沿ってスリット(切込み)を形成する。従って、吸収性物品の前部及び/又は後部が左右に開き易くすることにより、下層吸収体を更に隆起形状に変形させることができる。   In the invention described in claim 5, a slit (cut) is formed in the front part and / or the rear part of the absorbent article from the center of the front and rear end edges along the substantially longitudinal direction of the absorbent article. Therefore, by making the front part and / or the rear part of the absorbent article easily open to the left and right, the lower layer absorbent body can be further deformed into a raised shape.

請求項6に係る本発明として、前記上層吸収体のほぼ配設領域内であって、かつ吸収体中央部に吸収性物品の長手方向に沿って弾性伸縮部材を配設してある請求項1〜5いずれかに記載の吸収性物品が提供される。   According to a sixth aspect of the present invention, an elastic expansion / contraction member is disposed substantially in a region where the upper-layer absorbent body is disposed and at the center of the absorbent body along the longitudinal direction of the absorbent article. The absorbent article in any one of -5 is provided.

上記請求項6記載の発明においては、前記上層吸収体のほぼ配設領域内であって、かつ吸収体中央部に吸収性物品の長手方向に沿って弾性伸縮部材を配設することにより、前記上層吸収体を弾性伸縮部材の弾性力によって身体側に押し付けることができる。   In the invention of claim 6, the elastic stretchable member is disposed substantially in the region where the upper-layer absorbent body is disposed and along the longitudinal direction of the absorbent article at the center of the absorbent body. The upper layer absorbent body can be pressed against the body side by the elastic force of the elastic elastic member.

以上詳説のとおり本発明によれば、吸収体を立体形状(隆起形状)に変形させることにより股部凹凸への密着性を向上させることができる。   As described in detail above, according to the present invention, the adhesiveness to the crotch unevenness can be improved by deforming the absorbent body into a three-dimensional shape (a raised shape).

以下、本発明の実施の形態について図面を参照しながら詳述する。
図1は本発明に係る使い捨て紙おむつ1の製品状態外観図であり、図2はその展開図である。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a product state appearance view of a disposable paper diaper 1 according to the present invention, and FIG. 2 is a developed view thereof.

図1及び図2に示されるように、本パンツ型使い捨て紙おむつ1(以下、単に紙おむつという。)は、不織布などからなる透液性表面シート11と、ポリエチレン等からなる防漏シート12との間に、綿状パルプなどの吸収体13を介在させた吸収性本体10と、この吸収性本体10の外面側に一体的設けられた外装シート30とからなり、製品状態で前記外装シート30の前身頃と後身頃とが両側部において接合されることによりウエスト開口部及び左右一対のレッグ開口部が形成された構造のパンツ型紙おむつである。   As shown in FIGS. 1 and 2, the present pants-type disposable paper diaper 1 (hereinafter simply referred to as a paper diaper) is provided between a liquid-permeable surface sheet 11 made of nonwoven fabric and a leak-proof sheet 12 made of polyethylene or the like. The absorbent main body 10 having an absorbent body 13 such as cotton pulp interposed therebetween, and the exterior sheet 30 integrally provided on the outer surface side of the absorbent main body 10, and the predecessor of the exterior sheet 30 in a product state A pants-type disposable diaper having a structure in which a waist opening and a pair of left and right leg openings are formed by joining a back and a back body on both sides.

(吸収性本体10の構造)
先ず最初に、吸収性本体10の構造の一例について図4〜図10に基づいて詳述する。
(Structure of the absorbent main body 10)
First, an example of the structure of the absorbent main body 10 will be described in detail based on FIGS.

吸収性本体10は、前述したように、不織布などからなる透液性表面シート11と、ポリエチレン等からなる防漏シート12との間に、綿状パルプなどの吸収体13を介在させた構造とされ、体液を吸収保持するものである。   As described above, the absorbent main body 10 has a structure in which an absorbent body 13 such as cotton-like pulp is interposed between a liquid-permeable surface sheet 11 made of a nonwoven fabric or the like and a leak-proof sheet 12 made of polyethylene or the like. And absorbs and retains body fluids.

前記吸収体13は、下層吸収体14と、該下層吸収体14の身体側の面に重ねて配設されるとともに、前記下層吸収体14よりも小面積の1又は複数の、図示例では一層の上層吸収体15とから構成されている。なお、前記各吸収体14,15は、形状保持と透液性表面シート11を透過した体液の拡散性向上のためにクレープ紙によって囲繞されていることが望ましく、かつ嵩を小さくできるエアレイド吸収体を用いるのが望ましい。   The absorber 13 is disposed so as to overlap the lower-layer absorber 14 and the body-side surface of the lower-layer absorber 14, and has one or more smaller areas than the lower-layer absorber 14 in the illustrated example. And the upper layer absorber 15. Each of the absorbers 14 and 15 is preferably surrounded by crepe paper for maintaining the shape and improving the diffusibility of the body fluid that has passed through the liquid-permeable surface sheet 11, and the air-laid absorber that can reduce the volume. It is desirable to use

前記下層吸収体14は、図4に示されるように、下層吸収体14が長手方向中心線位置又はその近傍で左右に分割された左右一対の分割吸収体14A、14Bからなり、前記分割吸収体14A、14Bの境界が、長手方向に沿って横断方向に易変形性(角折れ変形性能)の可撓部分16となっている。また、前記下層吸収体14は、前部吸収体領域17A、股下部吸収体領域17B及び後部吸収体領域17Cとに区分することができ、前記股下部吸収体領域17Bの幅寸法Bminが前記前部吸収体領域17A及び後部吸収体領域17Cよりも幅狭(最狭部)となっている。 As shown in FIG. 4, the lower layer absorber 14 includes a pair of left and right divided absorbers 14 </ b> A and 14 </ b> B in which the lower layer absorber 14 is divided into left and right at or near the longitudinal center line position. The boundary between 14A and 14B is a flexible portion 16 that is easily deformable (corner-folding deformability) in the transverse direction along the longitudinal direction. The lower layer absorber 14 can be divided into a front absorber region 17A, a crotch absorber region 17B, and a rear absorber region 17C. The width dimension B min of the crotch absorber region 17B is It is narrower (the narrowest part) than the front absorber region 17A and the rear absorber region 17C.

そして、前記最狭部の両側部に、紙おむつの略長手方向に沿うように1又は複数本の、図示例では4本の隆起用弾性伸縮部材19,19…が配設されている。この隆起用弾性伸縮部材19,19…の始終端は前部吸収体領域17A、後部吸収体領域17Cに重なるか、その近傍に位置しているのが望ましい。前記弾性伸縮部材19としては、通常使用されるスチレン系ゴム、オレフィン系ゴム、ウレタン系ゴム、エステル系ゴム、ポリウレタン、ポリエチレン、ポリスチレン、スチレンブタジエン、シリコン、ポリエステル等の素材を用いることができる。   One or a plurality of, in the illustrated example, four elastic elastic members 19, 19 for raising are disposed on both sides of the narrowest portion so as to extend along the substantially longitudinal direction of the paper diaper. It is desirable that the starting and terminating ends of the elastic elastic members 19, 19,... As the elastic elastic member 19, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicon, polyester, and the like that are usually used can be used.

前記上層吸収体15は、下層吸収体14の股下部吸収体領域17Bから後部吸収体17Cにかけて該下層吸収体14の身体側の面(上面)に、前記可撓部分16に跨るように中央位置に配設されている。   The upper layer absorber 15 is located at a central position so as to straddle the flexible portion 16 on the body side surface (upper surface) of the lower layer absorber 14 from the crotch lower portion absorber region 17B to the rear absorber 17C of the lower layer absorber 14. It is arranged.

従って、前記隆起用弾性伸縮部材19,19…による伸縮力によって図中に白矢印で示すように、前部吸収体領域17Aの両側部と、後部吸収体領域17Cの両側部とが股下側に引き寄せられることにより、股下部吸収体領域17Bが長手方向断面で身体側に隆起するとともに、図5に示されるように、横断方向断面でも山折り状態となって身体面側に隆起する。そして、隆起部分の上面に重ねられた上層吸収体15が体液排出部から臀部側にかけて身体に密着して隙間を作らないため、体液漏れを確実に防止できるようになる。また、前記隆起部はパルプ等の積繊によるものではなく、前記下層吸収体14を立体形状に変形させることにより形成されるものであり、吸収体剛度を上げずに済むため、装着時に違和感や圧迫感を与えることがない。   Therefore, as shown by white arrows in the figure due to the elastic force of the elastic elastic members 19, 19..., Both side portions of the front absorbent body region 17A and both side portions of the rear absorbent body region 17C are on the crotch side. By being attracted, the crotch lower part absorber region 17B rises to the body side in the longitudinal section, and as shown in FIG. And since the upper-layer absorber 15 piled up on the upper surface of the raised portion is in close contact with the body from the body fluid discharge part to the buttocks side and does not form a gap, it is possible to reliably prevent body fluid leakage. In addition, the raised portion is not formed by pile fiber such as pulp, but is formed by deforming the lower layer absorbent body 14 into a three-dimensional shape, and it is not necessary to increase the rigidity of the absorbent body. There is no feeling of oppression.

この場合、図示されるように、前記上層吸収体15の配設領域内に対応する下層吸収体14部分に、吸収体の存在しないポケット空間18を形成することにより、前記ポケット空間18を形成している分割吸収体14A、14Bが装着状態で前記ポケット空間18を押し潰すように変形することによって、その上面側に配置された前記上層吸収体15を身体側に押し付けできるようになっている。   In this case, as shown in the figure, the pocket space 18 is formed by forming a pocket space 18 in which the absorber does not exist in the lower absorber 14 corresponding to the arrangement region of the upper absorber 15. When the divided absorbent bodies 14A and 14B are deformed so as to crush the pocket space 18 in the mounted state, the upper layer absorbent body 15 disposed on the upper surface side can be pressed against the body side.

ところで上記形態例では、下層吸収体14を構成する分割吸収体14A、14Bが、その前後部分において、対向する吸収体側縁が前後端縁側に行くに従って離間距離を漸次増大させるように曲線形状となっている。これは、いわゆる立体裁断によるものであり、紙おむつが装着された状態で前部吸収体領域17A及び後部吸収体領域17Cの分割吸収体14A、14Bが近接するように寄って装着される。   By the way, in the said form example, division | segmentation absorber 14A, 14B which comprises the lower layer absorber 14 becomes a curve shape so that a separation distance may increase gradually as the absorber side edge which opposes goes to the front-end edge side in the front-back part. ing. This is due to so-called draping, and the split absorbent bodies 14A and 14B of the front absorbent body region 17A and the rear absorbent body region 17C are attached so as to be close to each other with the paper diaper attached.

前記吸収体13の表面側(肌当接面側)を覆う透液性表面シート11としては、有孔または無孔の不織布や多孔性プラスチックシートなどが好適に用いられる。不織布を構成する素材繊維は、ポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。これらの加工法の内、スパンレース法は柔軟性、ドレープ性に富む点で優れ、サーマルボンド法は嵩高でソフトである点で優れている。透液性表面シート11に多数の透孔を形成した場合には、尿などが速やかに吸収されるようになり、ドライタッチ性に優れたものとなる。   As the liquid-permeable surface sheet 11 covering the surface side (skin contact surface side) of the absorbent body 13, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. The material fibers that make up the nonwoven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid-permeable surface sheet 11, urine and the like are quickly absorbed, and the dry touch property is excellent.

前記吸収体13の裏面側(非肌当接面側)を覆う防漏シート12は、ポリエチレンまたはポリプロピレンなどの不透液性プラスチックシートが用いられるが、近年はムレ防止の点から透湿性を有するものが好適に用いられる。この遮水・透湿性シートは、たとえばポリエチレンやポリプロピレン等のオレフィン樹脂中に無機充填材を溶融混練してシートを形成した後、一軸または二軸方向に延伸することにより得られる微多孔性シートであり、仮にシート厚が同じであれば無孔シートよりも剛性が低下するため、柔軟性の点で勝るものとなる。かかる防漏シート12としては、排便や尿などの褐色が出ないように不透明のものを用いるのが望ましい。不透明化としては、プラスチック中に、炭酸カルシウム、酸化チタン、酸化亜鉛、ホワイトカーボン、クレイ、タルク、硫酸バリウムなどの顔料や充填材を内添してフィルム化したものが好適に使用される。   The leak-proof sheet 12 covering the back surface side (non-skin contact surface side) of the absorbent body 13 is made of a liquid-impervious plastic sheet such as polyethylene or polypropylene, but in recent years has moisture permeability from the viewpoint of preventing stuffiness. Those are preferably used. This water-impervious / breathable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility. As the leak-proof sheet 12, it is desirable to use an opaque sheet so as not to cause browning such as defecation and urine. As the opacification, a plastic film and a pigment and filler such as calcium carbonate, titanium oxide, zinc oxide, white carbon, clay, talc and barium sulfate are preferably used.

一方、立体ギャザーBSを形成するギャザー不織布20は、少なくとも先端部分が折返しによって二重シートとした不織布が用いられ、前記二重シート内には複数本の糸状弾性伸縮部材21,21…が配設されている。前記糸状弾性伸縮部材21、21…は、製品状態において弾性伸縮力により突出する不織布部分を起立させて立体ギャザーBSを形成している。   On the other hand, the gathered nonwoven fabric 20 forming the three-dimensional gathered BS is a nonwoven fabric in which at least a tip portion is folded to form a double sheet, and a plurality of thread-like elastic elastic members 21, 21,. Has been. The thread-like elastic stretch members 21, 21... Form a three-dimensional gather BS by raising a non-woven fabric portion that protrudes due to elastic stretch force in a product state.

前記ギャザー不織布20を構成する素材繊維も前記透液性表面シート11と同様に、ポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工方法に得られた不織布を用いることができるが、特にはムレを防止するために坪量を抑えて通気性に優れた不織布を用いるのがよい。さらに前記ギャザー不織布20については、尿などの透過を防止するとともに、カブレを防止しかつ肌への感触性(ドライ感)を高めるために、シリコン系、パラフィン金属系、アルキルクロミッククロイド系撥水剤などをコーティングした撥水処理不織布を用いるのが望ましい。   In the same manner as the liquid-permeable surface sheet 11, the material fiber constituting the gathered nonwoven fabric 20 is made of synthetic fibers such as polyethylene or polypropylene such as olefin, polyester or polyamide, recycled fiber such as rayon or cupra, and cotton. Non-woven fabric obtained by an appropriate processing method such as a spunbond method, a thermal bond method, a melt blown method, a needle punch method, etc. can be used. It is preferable to use a nonwoven fabric that suppresses the basis weight and has excellent air permeability. Furthermore, with respect to the gathered nonwoven fabric 20, in order to prevent permeation of urine and the like, to prevent fogging, and to improve the touch to the skin (dry feeling), a silicon-based, paraffin metal-based, alkylchromic chromoid water repellent It is desirable to use a water-repellent non-woven fabric coated with such as.

前記吸収性本体10と外装シート30とは、図3に示されるように、外装シート30の上面側に吸収性本体10がホットメルト等の接着剤によって接着され一体化される。そして、吸収性本体10および外装シート30が前後方向に折り重ねられ、その両側部が相互に熱溶着またはホットメルト接着剤などによって接合されることにより、図1に示されるパンツ型紙おむつ1に組み立てられる。   As shown in FIG. 3, the absorbent main body 10 and the exterior sheet 30 are integrally bonded to the upper surface side of the exterior sheet 30 by an adhesive such as hot melt. Then, the absorbent main body 10 and the exterior sheet 30 are folded in the front-rear direction, and both sides thereof are joined to each other by heat welding or hot melt adhesive, thereby assembling the pants-type paper diaper 1 shown in FIG. It is done.
