Description

吸収性物品Absorbent articles
 本発明は、吸収性物品に関する。 The present invention relates to an absorbent article.
 吸収性物品の一例として生理用ナプキンが挙げられる。特許文献1には、ドッド状エンボス7が形成された吸収体4を有する生理用ナプキン1が開示されている。このドッド状エンボス7によって設けられた繊維密度差による毛管現象作用で吸収性能を向上させることが示されている。 An example of an absorbent article is a sanitary napkin. Patent Document 1 discloses a sanitary napkin 1 having an absorbent body 4 on which a dodd-like emboss 7 is formed. It is shown that the absorption performance is improved by the capillary action by the fiber density difference provided by the dodd-like emboss 7.
特開2008-136564号公報JP 2008-136564 A
 しかし、上記特許文献1の生理用ナプキン1では、ドッド状エンボス7が規則的パターンで設けられているため、体液排出部位を示す領域Hで吸収した体液を毛管現象作用で移行させることで略同心円状に体液が拡散されることになる。このとき、生理用ナプキン1のような吸収性物品では、吸収体4の長手方向の長さは用途に応じて調整することができるが、幅方向の長さは使用者の股の長さによって制限されるため、幅方向の長さの方が短くなる。そのため、長手方向に吸収できる範囲が広く設けられているにも関わらず、略同心円状に拡散された体液が吸収体4の幅方向の端から漏れてしまう恐れがある。 However, in the sanitary napkin 1 of the above-mentioned patent document 1, since the dodd-like embosses 7 are provided in a regular pattern, the body fluid absorbed in the region H indicating the body fluid discharge site is transferred by capillary action, so that it is substantially concentric. The body fluid is diffused in a shape. At this time, in the absorbent article such as the sanitary napkin 1, the length in the longitudinal direction of the absorbent body 4 can be adjusted according to the application, but the length in the width direction depends on the length of the user's crotch. Since it is limited, the length in the width direction becomes shorter. Therefore, the body fluid diffused substantially concentrically may leak from the end of the absorbent body 4 in the width direction although the range that can be absorbed in the longitudinal direction is wide.
 本発明は、上記のような問題に鑑みてなされたものであって、吸収体のより広い範囲で排泄物を吸収させることを目的とする。 The present invention has been made in view of the above problems, and an object thereof is to absorb excrement in a wider range of the absorber.

<About the center guide | induction part 14, the absorber dotted | punctate pressing part 15, and the pressing part 25>
FIG. 4 is a plan view of the absorbent body 10 as viewed from the non-skin side. FIG. 5 is an enlarged schematic view of the absorber point-like squeezed portion 15 when the absorber 10 is viewed from the skin side. Of the vertically long absorbent body 10 in plan view, the end along the longitudinal direction on both outer sides in the width direction is respectively the lateral end 10e, the front curved end in the longitudinal direction is the front end 10et, and the rear curved end is This is referred to as a rear end 10eb.

Moreover, the planar shape of the absorber squeezed compressed portion 15 is an ellipse having a longer length Lm1 in the longitudinal direction than the length Lm2 in the width direction (Lm1> Lm2), and promotes diffusion of excrement and the like in the longitudinal direction. ing.
 吸収体点状圧搾部15は、幅方向に隣接する吸収体点状圧搾部15同士の中心の間隔が均等であり、長手方向に隣接する吸収体点状圧搾部15同士の中心の間隔が均等である。これにより、吸収体10の剛性を一定にしつつ、排泄物等の拡散を一定にすることができる。また、幅方向に隣接する吸収体点状圧搾部15同士の縁の間隔をLbは、吸収体点状圧搾部15の幅方向の長さLm2より短い(Lm2>Lb)。長手方向に隣接する吸収体点状圧搾部15の縁の間隔Ljは、幅方向に隣接する吸収体点状圧搾部15同士の縁の間隔Lbより短い(Lj<Lb)。 As for the absorber dotted | punctate pressing part 15, the space | interval of the center of the absorber dotted | punctate pressing parts 15 adjacent to the width direction is equal, and the center gap | interval of the absorber dotted | punctate pressing parts 15 adjacent to a longitudinal direction is equal. It is. Thereby, diffusion of excrement etc. can be made constant, making the rigidity of absorber 10 constant. Moreover, Lb is shorter than the length Lm2 of the width direction of the absorber dot-shaped pressing part 15 between the edges of the absorber dot-shaped pressing parts 15 adjacent in the width direction (Lm2> Lb). The distance Lj between the edges of the absorber point-shaped compressed parts 15 adjacent in the longitudinal direction is shorter than the distance Lb between the edges of the absorber point-shaped compressed parts 15 adjacent in the width direction (Lj <Lb).
 吸収体10には、幅方向の中央部に長手方向に沿った中央誘導部14が設けられている。中央誘導部14は、吸収体10の前端10etから後端10ebまで、肌側及び非肌側からそれぞれ厚さ方向に凹んでいる。中央誘導部14は、中央誘導部14を基点として吸収体10を厚さ方向の肌側に折れ曲がるように誘導し、かつ、排泄物等を長手方向に誘導する。中央誘導部14による折れ曲がりの誘導と排泄物の誘導の詳細は後述する。 The absorber 10 is provided with a central guiding portion 14 along the longitudinal direction at the central portion in the width direction. The center guiding portion 14 is recessed in the thickness direction from the skin side and the non-skin side from the front end 10et to the rear end 10eb of the absorbent body 10, respectively. The center guide part 14 guides the absorbent body 10 to bend toward the skin side in the thickness direction with the center guide part 14 as a base point, and guides excrement and the like in the longitudinal direction. The details of bending induction and excretion induction by the central guide 14 will be described later.

FIG. 6A is a schematic cross-sectional view in which an absorbent dot-like compressed portion 15 is formed in the portion of the absorbent body 10 indicated by arrows EE in FIG. FIG. 6B is a schematic cross-sectional view in which a central guide portion 14 is formed in the absorber 10 of FIG. 6A. 6C is a schematic cross-sectional view in which the top sheet 3 is laminated on the absorbent body 10 of FIG. 6B. FIG. 6D is a schematic cross-sectional view of the napkin 1 at a portion indicated by arrows EE in FIG. 6A, 6B, and 6C, the yy line is the center line of the absorber 10 in the thickness direction, and YY in FIG. 6D is the center line of the napkin 1 in the thickness direction. . The center guide | induction part 14, the absorber dotted | punctate pressing part 15, and the dotted | punctate pressing part 25 are the roll gap | intervals between the convex roller (not shown) which has a some protrusion, and the anvil roller (not shown) with a flat surface. It is formed by squeezing through the absorbent body 10 or the absorbent body 10 in which the top sheet 3 is stacked.
 まず、吸収体点状圧搾部15を形成する。加工前の吸収体10に非肌面側から圧搾(エンボス加工)すると、吸収体点状圧搾部15が形成され、圧搾されていない領域aと、圧搾加工されて肌側及び非肌側から凹んだ領域bとが形成される(図6A)。領域bは液体吸収性繊維が押し潰されて、領域aより厚みが薄くなり、領域aより液体吸収性繊維の密度が高くなる。つまり、液体吸収性繊維の密度は、幅方向における、吸収体点状圧搾部15の中央部bcの方が、吸収体点状圧搾部15の端部より高い。このとき、吸収体点状圧搾部15は、吸収体10の厚さ方向における略中央部に位置している。 First, the absorber squeezed compressed portion 15 is formed. When the absorbent body 10 before processing is squeezed (embossed) from the non-skin surface side, the absorber squeezed portion 15 is formed, and the squeezed region a is squeezed and recessed from the skin side and non-skin side. A region b is formed (FIG. 6A). In the region b, the liquid absorbent fibers are crushed, the thickness is thinner than the region a, and the density of the liquid absorbent fibers is higher than the region a. That is, the density of the liquid absorbent fiber is higher in the center portion bc of the absorber point-like compressed portion 15 than in the end portion of the absorber point-like pressed portion 15 in the width direction. At this time, the absorber dotted compression part 15 is located in the approximate center part in the thickness direction of the absorber 10.
 続いて、中央誘導部14を形成する。中央誘導部14は、吸収体点状圧搾部15が形成された吸収体10の吸収体の幅方向の中央部に非肌面側から賦型・圧搾加工をすると、中央誘導部14が形成され、新たに肌側及び非肌側から凹んだ領域cが形成される(図6B)。領域cは、吸収体点状圧搾部15と同様に、液体吸収性繊維が押し潰されて、領域aより厚みが薄くなり、領域aより液体吸収性繊維の密度が高くなる。つまり、液体吸収性繊維の密度が、幅方向において、中央誘導部14の中央部ccの方が、中央誘導部14の端部よりも高い。 Subsequently, the central guide portion 14 is formed. When the central guiding portion 14 is subjected to shaping / squeezing from the non-skin surface side to the central portion in the width direction of the absorbent body of the absorbent body 10 in which the absorbent body point-like compressed portion 15 is formed, the central guiding portion 14 is formed. A region c newly recessed from the skin side and the non-skin side is formed (FIG. 6B). In the area c, the liquid absorbent fibers are crushed, the thickness is thinner than the area a, and the density of the liquid absorbent fibers is higher than that of the area a, similarly to the absorbent point squeezed portion 15. That is, the density of the liquid absorbent fibers is higher in the central portion cc of the central guiding portion 14 than in the end portion of the central guiding portion 14 in the width direction.
 なお、液体吸収性繊維の密度は、中央誘導部14の中央部ccより、吸収体点状圧搾部15の中央部bcの方が高いことが好ましい。これは、吸収体点状圧搾部15を形成する圧搾を、中央誘導部14を形成する圧搾より大きな加圧で行うことで実現できる。これにより、まず中央誘導部14で吸収した排泄物を、液体吸収性繊維の密度がより高い吸収体点状圧搾部15に誘導することができる。ただし、吸収体点状圧搾部15を形成した部分に、さらに中央誘導部14を形成した場合には、部分的に中央誘導部14の厚みがより薄くなり、液体吸収性繊維の密度がより高くなる。 In addition, it is preferable that the density of a liquid absorptive fiber is higher in the central part bc of the absorbent body point-like compressed part 15 than in the central part cc of the central guiding part 14. This can be realized by performing the squeezing that forms the absorber point squeezed portion 15 with a larger pressure than the squeezing that forms the central guiding portion 14. Thereby, the excrement absorbed with the center guidance | induction part 14 can be first induced | guided | derived to the absorber dotted | punctate pressing part 15 where the density of a liquid absorptive fiber is higher. However, in the case where the central guiding portion 14 is further formed in the portion where the absorber squeezed compressed portion 15 is formed, the thickness of the central guiding portion 14 is partially thinner, and the density of the liquid absorbent fibers is higher. Become.
 続いて、図6Cに示すように吸収体10の肌側からトップシート3を積層し、接着剤(HMA)により固着する。なお、図6C及び図6Dでは接着剤を省略している。 Subsequently, as shown in FIG. 6C, the top sheet 3 is laminated from the skin side of the absorbent body 10, and is fixed by an adhesive (HMA). In FIG. 6C and FIG. 6D, the adhesive is omitted.
 そして、点状圧搾部25を形成する。トップシート3と吸収体10とを厚さ方向に一緒に肌面側から圧搾して、新たに肌側から凹んだ領域dが形成される(図6D)。その後、非肌側にバックシート5を積層して、接着剤で固着してナプキン1とする。領域dは、液体吸収性繊維が更に押し潰されて、領域aより厚みが薄くなり、領域aより液体吸収性繊維の密度が高くなる。つまり、液体吸収性繊維の密度は、幅方向における、点状圧搾部25の中央部dcの方が、点状圧搾部25の端部より高い。このとき、点状圧搾部25は、ナプキン1の厚さ方向における略中央部に位置している。なお、図6Dでは、吸収体点状圧搾部15が形成された部分に点状圧搾部25を形成したが、これに限られない。吸収体点状圧搾部15と点状圧搾部25を同じ位置に形成しても、別々の位置に形成してもよい。 And the point-like pressing part 25 is formed. The top sheet 3 and the absorbent body 10 are squeezed together in the thickness direction from the skin surface side to form a newly recessed region d from the skin side (FIG. 6D). Thereafter, the back sheet 5 is laminated on the non-skin side and fixed with an adhesive to form the napkin 1. In the region d, the liquid absorbent fibers are further crushed, the thickness is thinner than the region a, and the density of the liquid absorbent fibers is higher than the region a. That is, the density of the liquid absorbent fibers is higher in the central portion dc of the point-like compressed portion 25 than in the end portion of the point-like compressed portion 25 in the width direction. At this time, the point-like compressed portion 25 is located at a substantially central portion in the thickness direction of the napkin 1. In addition, in FIG. 6D, although the dotted | punctate pressing part 25 was formed in the part in which the absorber dotted | punctate pressing part 15 was formed, it is not restricted to this. Even if the absorber dotted | punctate pressing part 15 and the dotted | punctate pressing part 25 are formed in the same position, you may form in a separate position.
 <圧搾部26、27、28、29について>
 また、ナプキン1には、厚さ方向の肌側から非肌側に向かって凹んでいて、隣接する部位に比べて液体吸収性繊維の密度の高い線状の圧搾部26、27、28、29が設けられている。この圧搾部26、27、28、29によって、トップシート3と吸収体が厚さ方向の肌側から圧搾(エンボス加工)され、接合一体化されている。圧搾部26、27、28は、全体として長手方向に長い略環状を成しており、吸収体10の外周縁部に沿って、圧搾部26と圧搾部27と圧搾部28が連なって形成されている。

 <中央誘導部14による吸収体10を肌側に折り曲げる誘導について>
 吸収体10に設けられた中央誘導部14が、厚さ方向に凹んだ中央誘導部14を基点として、吸収体10を厚さ方向の肌側に折れ曲がるように誘導することができるため、ナプキン1の着用時に、着用者の脚の挟み込みの力が作用すると、吸収体10の長手方向の中央領域は、幅方向の側部から中央部に向かって肌側に凸となる形状に変形する。図7は、ナプキン1の使用態様について説明する図である。使用者がナプキン1を装着する際には、ナプキン1を下着の股下部(クロッチ部)に固定した状態で、下着を使用者の股間201K側に引き上げる動作を行う。このとき、図7の状態Aで表されるように吸収体10を備えたナプキン1は、中央誘導部14に沿って肌側に折れ曲がる。そして、ナプキン1が使用者の股間201Kに装着された状態では、図7の状態Bで表されるように、中央誘導部14に沿って肌側に折れ曲がった部分が膣口等の排泄口201Heが存在する隙間に接しやすくなる。これにより、使用者に良好なフィット性を感じさせ易くなると共に、経血等の排泄物を漏れなく吸収体10に吸収させ易くすることができる。
<About the guidance which bends the absorber 10 by the center guidance part 14 to the skin side>
Since the central guiding portion 14 provided in the absorbent body 10 can guide the absorbent body 10 to bend toward the skin side in the thickness direction with the central guiding portion 14 recessed in the thickness direction as a base point, the napkin 1 When a wearer's leg pinching force is applied at the time of wearing, the central region in the longitudinal direction of the absorbent body 10 is deformed into a convex shape toward the skin side from the side portion in the width direction toward the central portion. FIG. 7 is a diagram illustrating a usage mode of the napkin 1. When the user wears the napkin 1, an operation of pulling up the underwear toward the user's crotch 201K side is performed with the napkin 1 fixed to the crotch part (crotch portion) of the underwear. At this time, the napkin 1 provided with the absorbent body 10 as shown in the state A of FIG. 7 bends to the skin side along the central guiding portion 14. In the state where the napkin 1 is attached to the user's crotch 201K, as represented by the state B in FIG. 7, the portion bent to the skin side along the central guiding portion 14 is the excretion opening 201He such as the vaginal opening.

 <中央誘導部14による排泄物の誘導について>
 中央誘導部14は、長手方向に沿った形状で、圧搾加工によって厚さ方向に凹ませ、液体吸収性繊維の密度を高めているため、排泄物等の液体を長手方向に誘導することができる。以下、排泄物等の液体の拡散性について説明する。本実施形態において、吸収体10における排泄物等の拡散は、吸収体10内の液体吸収性繊維の割合が多いため(液体吸収性繊維:SAP=90:10)、所謂「毛管現象」によって、排泄物等の拡散が促されている。「毛管現象」とは、「毛細管現象」ともいい、管中の液面の上昇又は効果の度合いは液体の表面張力に比例し、管の内径に反比例することをいう。本実施形態においては、繊維と繊維の間の空間が管に相当し、繊維と繊維の間の狭い空間を重力や上下左右関係なく液体が浸透していく現象をいい、液体吸収性繊維の隙間が狭いほど液体の浸透が速まる。つまり、液体吸収性繊維の密度が高いほど、排泄物がより拡散する。
<About the induction of excrement by the central guide 14>
The central guiding portion 14 has a shape along the longitudinal direction and is dented in the thickness direction by pressing to increase the density of the liquid-absorbing fibers, so that liquid such as excrement can be guided in the longitudinal direction. . Hereinafter, the diffusibility of liquid such as excreta will be described. In the present embodiment, the diffusion of excrement etc. in the absorbent body 10 is due to a large proportion of liquid absorbent fibers in the absorbent body 10 (liquid absorbent fibers: SAP = 90: 10). The diffusion of excrement etc. is promoted. “Capillary phenomenon” is also referred to as “capillary phenomenon”, and means that the rise of the liquid level in the tube or the degree of effect is proportional to the surface tension of the liquid and inversely proportional to the inner diameter of the tube. In this embodiment, the space between the fibers corresponds to a tube, and refers to a phenomenon in which liquid permeates through a narrow space between the fibers regardless of gravity or top / bottom / left / right. The narrower the is, the faster the liquid penetrates. In other words, the higher the density of the liquid absorbent fibers, the more the excreta diffuses.
 図8A~図8Dは、本実施形態の吸収体10と同様にトップシート、吸収性コア、バックシートを有する吸収体であり、所定量の液体を滴下し、一定時間経過後の状態を示している。図8A~図8Dにおいて、各図面の上下方向は長手方向、左右方向は幅方向を示している。 8A to 8D are absorbent bodies having a top sheet, an absorbent core, and a back sheet similarly to the absorbent body 10 of the present embodiment, and show a state after a predetermined amount of liquid has been dropped and a predetermined time has elapsed. Yes. 8A to 8D, the vertical direction of each drawing indicates the longitudinal direction, and the horizontal direction indicates the width direction.
 まず、図8Aは、吸収体点状圧搾部及び中央誘導部を有さない吸収体について説明する図である。この場合、吸収体点状圧搾部と中央誘導部を有していないため、滴下された液体がその場でほぼ同心円状で、滴下された場所でほぼ留まっている。 First, FIG. 8A is a diagram illustrating an absorbent body that does not have the absorbent body point-like compressed portion and the central guide portion. In this case, since it does not have an absorber dotted | punctate pressing part and a center induction | guidance | derivation part, the dripped liquid is substantially concentric on the spot, and has almost remained at the dripped place.
 図8Bは、吸収体点状圧搾部を有し、中央誘導部を有さない吸収体について説明する図である。この場合は、滴下された液体は、液体吸収性繊維の密度が高くなった吸収体点状圧搾部の毛管現象によって、隣接する吸収体点状圧搾部間へと促され、図8Aの場合よりも広い範囲に拡散している。このとき、液体は、長手方向及び幅方向に同程度拡散して、ほぼ同心円状に拡散している。 FIG. 8B is a diagram illustrating an absorbent body that has an absorbent point-like compressed portion and does not have a central guiding portion. In this case, the dropped liquid is urged between the adjacent absorbent point-like compressed parts by the capillary phenomenon of the absorbent point-like compressed part in which the density of the liquid absorbent fibers is increased, as compared with the case of FIG. 8A. Is also widespread. At this time, the liquid diffuses in the longitudinal direction and the width direction to the same extent, and diffuses substantially concentrically.
 図8Cは、吸収体点状圧搾部を有しておらず、中央誘導部を有する吸収体について説明する図である。そのため、滴下された液体は、液体吸収性繊維の密度が高くなった中央誘導部の毛管現象によって、中央誘導部に沿って液体の拡散が促され、幅方向には液体の拡散があまり進んでいないが、中央誘導部に沿った部分については液体がより長く拡散されている。 FIG. 8C is a diagram illustrating an absorbent body that does not have an absorbent point-like compressed portion but has a central guiding portion. For this reason, the dropped liquid is promoted to diffuse along the central guiding portion due to the capillary phenomenon of the central guiding portion where the density of the liquid absorbent fibers is increased, and the diffusion of the liquid is not so advanced in the width direction. However, the liquid is diffused longer in the portion along the central guiding portion.
 図8Dは、吸収体点状圧搾部と中央誘導部を有する吸収体について説明する図である。液体吸収性繊維の密度が高くなった吸収体点状圧搾部の毛管現象によって、隣接する吸収体点状圧搾部間へと促され、液体吸収性繊維の密度が高くなった中央誘導部の毛管現象によって、中央誘導部に沿って液体の拡散が促される。その結果、幅方向にも長手方向にも液体の拡散が促されている。このとき、吸収体点状圧搾部のみを形成した場合(図8B)は、ほぼ同心円状に液体が拡散していたのに対し、中央誘導部による液体の拡散によって、吸収体点状圧搾部による液体の拡散効果と中央誘導部による液体の拡散効果が組み合わされて、液体が拡散した領域が縦長の楕円形状となる(図8D)。吸収体に均一の間隔で形成された吸収体点状圧搾部は、幅方向及び長手方向へ拡散し、排泄物等が広がった範囲を略同心円状とする。中央誘導部は、吸収体の長手方向に沿って形成されており、液体をより長手方向へ拡散させる。 FIG. 8D is a diagram illustrating an absorbent body having an absorbent spot-like compressed portion and a central guide portion. The capillary tube of the central guiding part where the density of the liquid absorbent fibers is increased by the capillary phenomenon of the absorbent spot-like squeezed parts where the density of the liquid absorbent fibers is increased, and the density of the liquid absorbent fibers is increased. The phenomenon promotes liquid diffusion along the central guide. As a result, liquid diffusion is promoted both in the width direction and in the longitudinal direction. At this time, when only the absorber squeezed portion is formed (FIG. 8B), the liquid has been diffused substantially concentrically, whereas the liquid is diffused by the central guide portion, so that the absorber squeezed portion is used. The liquid diffusing effect and the liquid diffusing effect by the central guiding portion are combined, and the region in which the liquid diffuses becomes a vertically long elliptical shape (FIG. 8D). Absorber squeeze-shaped compressed parts formed in the absorbent body at uniform intervals diffuse in the width direction and the longitudinal direction, and the range in which excrement and the like spreads is substantially concentric. The central guiding portion is formed along the longitudinal direction of the absorber, and diffuses the liquid in the longitudinal direction more.
 中央誘導部は、中央誘導部の凹み(圧搾)の深さや、長手方向の長さ及び、中央誘導部が形成された面積等を変化させることで、液体の拡散量を変化させることができる。例えば、より高圧力な圧搾によって形成された中央誘導部は、液体吸収性繊維の密度が高くなり、長手方向への液体の拡散をより促すことができる。また、より長く、より面積の広い中央誘導部は、液体吸収性繊維の密度が高い領域が広くなるため、長手方向への液体の拡散をより促すことができる。 The central guiding portion can change the amount of liquid diffusion by changing the depth of depression (squeezing) of the central guiding portion, the length in the longitudinal direction, the area where the central guiding portion is formed, and the like. For example, the central guide portion formed by higher pressure squeezing increases the density of the liquid absorbent fibers and can further promote the diffusion of the liquid in the longitudinal direction. Further, the longer and wider central guiding portion has a larger area where the density of the liquid-absorbing fibers is high, so that it is possible to further promote the diffusion of the liquid in the longitudinal direction.
 例えば、吸収体に所定量(例えば、5ml)の人工経血等の液体を吸収体の略中央に滴下し、所定時間(例えば、60分後)経過後の状態を観察する。その結果に応じて中央誘導部の調整を行うことができる。長手方向への拡散が不十分であると判断できる場合には、中央誘導部の圧搾をより強くしたり、中央誘導部の幅方向の長さをより長くしたりすればよい。また、中央誘導部の長手方向の長さをより長くすることで、吸収体の長手方向のより外側に液体を拡散することもできる。さらに、液体吸収性繊維とSAPとを有する吸収体について、液体吸収性繊維の割合をより一層増やすことで、液体の拡散性を向上させることもできる。一方、長手方向への拡散が進み過ぎていると判断できる場合には、中央誘導部の圧搾をより弱くしたり、中央誘導部の幅方向の長さを短く、狭い範囲に形成したりすればよい。また、吸収体のSAPの構成比を増やしてもよい。 For example, a predetermined amount (for example, 5 ml) of liquid such as artificial menstrual blood is dropped on the absorber in the approximate center of the absorber, and the state after a predetermined time (for example, after 60 minutes) is observed. The central guiding portion can be adjusted according to the result. When it can be determined that the diffusion in the longitudinal direction is insufficient, the central guiding portion may be squeezed more strongly or the width of the central guiding portion in the width direction may be increased. Moreover, the liquid can also be diffused further outside in the longitudinal direction of the absorbent body by making the length of the central guiding portion in the longitudinal direction longer. Furthermore, about the absorber which has a liquid absorptive fiber and SAP, the diffusibility of a liquid can also be improved by further increasing the ratio of a liquid absorptive fiber. On the other hand, if it can be determined that diffusion in the longitudinal direction has progressed too much, if the compression of the central guiding portion is weakened or the length of the central guiding portion in the width direction is short and formed in a narrow range Good. Moreover, you may increase the component ratio of SAP of an absorber.
 さらに、中央誘導部だけでなく、中央誘導部と、点状及び線状の圧搾部を組合せることにより、液体の拡散をより柔軟に調整することができる。中央誘導部、点状及び線状の圧搾部の圧搾範囲や圧搾の強さ等についても、上記の中央誘導部の調整と同様に、その状態を観察して決定すればよい。 Furthermore, the diffusion of liquid can be adjusted more flexibly by combining not only the central guiding part but also the central guiding part and the point-like and linear pressing parts. What is necessary is just to observe the state similarly to adjustment of said center induction | guidance | derivation, and to determine also about the compression range of the center induction | guidance | derivation part, a dotted | punctate, and a linear compression part, the strength of expression, etc.
 例えば、幅方向への液体の拡散が進み過ぎて、長手方向への液体の拡散が不十分である場合には、中央誘導部をより強い圧搾で形成して長手方向への拡散を促す一方、点状の圧搾部の数を減らして幅方向への液体の拡散を減らしてもよい。同様に、長手方向への液体の拡散が適度に行われ、幅方向への液体の拡散が不十分である場合には、中央誘導部はそのままで、点状の圧搾部の数や圧搾量を増やすことで、幅方向への拡散をより促すことができる。さらに、点状の圧搾部の長手方向の密度と、点状の圧搾部の幅方向の密度を変えることによっても、長手方向への液体の拡散と幅方向への液体の拡散とを変化させることができる。 For example, if the diffusion of the liquid in the width direction has progressed too much and the diffusion of the liquid in the longitudinal direction is insufficient, the central guide portion is formed by stronger squeezing to promote the diffusion in the longitudinal direction, You may reduce the spreading | diffusion of the liquid to the width direction by reducing the number of dotted | punctate pressing parts. Similarly, when the diffusion of the liquid in the longitudinal direction is moderately performed and the diffusion of the liquid in the width direction is insufficient, the number of the squeezed squeezed parts and the amount of squeezed parts can be set without changing the central guiding part. By increasing the number, diffusion in the width direction can be further promoted. Furthermore, the liquid diffusion in the longitudinal direction and the liquid diffusion in the width direction can be changed also by changing the density in the longitudinal direction of the point-like compressed portion and the density in the width direction of the point-like compressed portion. Can do.

 図10Cは、図10Aのナプキン100に液体を滴下し、所定時間経過後の状態を示す模式図である。図10Aのナプキン100に、3.0mlの液体を滴下して1時間経過した状態を表している。このとき、排泄物存在領域qは、図10Bの状態より広くなり、長手方向の長さT及び幅方向の長さSがそれぞれ約75mmの略同心円形状で、吸収体101の長手方向には収まっているが、幅方向の両外側にはみ出している。そのため、吸収体101の前側領域及び後側領域は、ほとんど液体を吸収していないが、吸収体101の幅方向の端から液体が漏れてしまい、ナプキン1の外側にも液体が漏れてしまう恐れを生じる可能性がある。 FIG. 10C is a schematic diagram showing a state after a predetermined time has elapsed after a liquid is dropped on the napkin 100 of FIG. 10A. FIG. 10A shows a state where 3.0 ml of liquid is dropped on the napkin 100 in FIG. 10A and one hour has passed. At this time, the excreta present region q is wider than the state of FIG. 10B, and has a substantially concentric shape with a length T in the longitudinal direction and a length S in the width direction of about 75 mm, and fits in the longitudinal direction of the absorbent body 101. However, it protrudes to both outer sides in the width direction. Therefore, the front region and the rear region of the absorbent body 101 hardly absorb the liquid, but the liquid leaks from the end in the width direction of the absorbent body 101, and the liquid may leak to the outside of the napkin 1. May occur.
 一方、本実施形態にかかるナプキン1は、中央誘導部14及び圧搾部26、27、28、29を有している。図11Aは、ナプキン1の使用前の状態を示す模式図である。なお、本実施形態のナプキン1は、排泄物存在領域qの長手方向の長さTの半分(T/2)を、幅方向の長さSで除した値((T/2)/S)が、前側圧搾部26aの前側の端26aeからウィング粘着部中心線W-Wまでの距離Hを、ウィング粘着部中心線W-Wにおける吸収体10の幅方向の長さKで除した値(H/K)以上とする((T/2)/S≧H/K)、中央誘導部14を備えている。 On the other hand, the napkin 1 according to the present embodiment includes the central guide portion 14 and the pressing portions 26, 27, 28, and 29. FIG. 11A is a schematic diagram showing a state of the napkin 1 before use. In addition, the napkin 1 of this embodiment is a value ((T / 2) / S) obtained by dividing half (T / 2) of the length T in the longitudinal direction of the excreta present region q by the length S in the width direction. Is a value obtained by dividing the distance H from the front end 26ae of the front compressed portion 26a to the wing adhesive portion center line WW by the length K in the width direction of the absorbent body 10 at the wing adhesive portion center line WW ( H / K) or more ((T / 2) / S ≧ H / K).
 ここで、前述したように、排泄物等の拡散状態は、中央誘導部の圧搾状態や形状、点状の圧搾部の圧搾状態や分布状態等によって変化する。そこで、例えば、次のような手順により、(T/2)/S≧H/Kを実現する中央誘導部14を形成することが可能となる。まず、点状圧搾部25の分布密度のみ異なる3種類のナプキン(圧搾部26、27、28、29は同じ、中央誘導部14は未形成)を準備する。次に、各ナプキンに対して、圧力を変えて中央誘導部14(長さは同じ)を圧搾する。これにより、中央誘導部14の圧搾状態のみ異なる3種類のナプキンが得られる。次に、これらのナプキンに対して、前述したように液体(人工経血等)を滴下して拡散状態を観察し、(T/2)/S≧H/Kとなるナプキンを特定する。
(T/2)/S≧H/Kとなるナプキンが特定されれば、それに形成された中央誘導部14を採用すればよい。もし、(T/2)/S≧H/Kとなるナプキンが存在しなければ、上記の実験結果を踏まえて、より長手方向(又は幅方向)に拡散させるべく、前述したように、中央誘導部14の幅や長さを変える等の対応を行なえばよい。
Here, as described above, the diffusion state of the excrement and the like changes depending on the squeezed state and shape of the central guiding portion, the squeezed state and distribution state of the dotted squeezed portion, and the like. Therefore, for example, the central guiding portion 14 that realizes (T / 2) / S ≧ H / K can be formed by the following procedure. First, three types of napkins (squeezed portions 26, 27, 28, and 29 are the same, and the central guiding portion 14 is not formed) that differ only in the distribution density of the point-like compressed portions 25 are prepared. Next, for each napkin, the pressure is changed to squeeze the central guide portion 14 (the length is the same). Thereby, three types of napkins that differ only in the compressed state of the central guiding portion 14 are obtained. Next, as described above, a liquid (artificial menstrual blood or the like) is dropped on these napkins and the diffusion state is observed to identify napkins satisfying (T / 2) / S ≧ H / K.
If a napkin satisfying (T / 2) / S ≧ H / K is specified, the central guiding portion 14 formed thereon may be employed. If there is no napkin satisfying (T / 2) / S ≧ H / K, based on the result of the above experiment, as described above, the central guide is used in order to diffuse more in the longitudinal direction (or the width direction). What is necessary is just to respond | correspond, such as changing the width | variety and length of the part 14. FIG.
 次に、以上のようにして得られたナプキン((T/2)/S≧H/Kとなるナプキン)における排泄物の拡散状態について、図を用いてより詳しく説明する。図11Bは、図11Aのナプキン1に液体を滴下し、所定時間経過後の状態を示す模式図である。図11Aのナプキン1に、0.5mlの液体を滴下して1時間経過した状態を表している。このとき、排泄物存在領域qは、長手方向の長さTが約60mm、幅方向の長さSが約30mmの縦長の楕円形状となり、吸収体10の内側に収まっている。 Next, the diffusion state of excrement in the napkin ((T / 2) / S ≧ H / K satisfying napkin) obtained as described above will be described in more detail with reference to the drawings. FIG. 11B is a schematic diagram illustrating a state after a predetermined time has elapsed after a liquid is dropped on the napkin 1 of FIG. 11A. FIG. 11A shows a state in which 0.5 ml of liquid has been dropped on the napkin 1 in FIG. 11A and one hour has elapsed. At this time, the excreta present region q has a vertically long elliptical shape with a length T of about 60 mm in the longitudinal direction and a length S of about 30 mm in the width direction, and is contained inside the absorber 10.
 図11Cは、図11Aのナプキン1に液体を滴下し、所定時間経過後の状態を示す模式図である。図11Aの状態のナプキン1に3.0mlの液体を滴下して1時間経過した状態を表している。このとき、排泄物存在領域qは、長手方向の長さTが約120mm、幅方向の長さSが約60mmの縦長の楕円形状となり、吸収体10の内側に収まっている。 FIG. 11C is a schematic diagram showing a state after a liquid has been dropped on the napkin 1 of FIG. 11A and a predetermined time has elapsed. The state which dripped 3.0 ml of liquid on the napkin 1 of the state of FIG. At this time, the excreta present region q has a vertically long elliptical shape with a length T in the longitudinal direction of about 120 mm and a length S in the width direction of about 60 mm, and is contained inside the absorber 10.
 図11B及び図11Cに示すように、本実施形態のナプキン1は、吸収体10の中心線X-Xとウィング粘着部中心線W-Wとの交差する部分で吸収した排泄物等を、中央誘導部14が、幅方向よりも長手方向へ拡散させている。排泄物存在領域qの長手方向の長さTの半分(T/2)を、幅方向の長さSで除した値((T/2)/S)が、前側圧搾部26aの前側の端26aeからウィング粘着部中心線W-Wまでの距離Hを、ウィング粘着部中心線W-Wにおける吸収体10の幅方向の長さKで除した値(H/K)以上とすることで((T/2)/S≧H/K)、いずれの状態においても排泄物存在領域qを吸収体10の内側に収めており、吸収体10のより広い範囲に排泄物を拡散しつつ、吸収体10の幅方向の外側に排泄物が漏れる恐れを軽減している。つまり、排泄物存在領域qが吸収体10の横端10eに達するより前に前側圧搾部26aに達するように排泄物を誘導することができ、ナプキン100の吸収体101の場合よりも、吸収体10のより広い範囲で排泄物等を吸収させることができる。 As shown in FIG. 11B and FIG. 11C, the napkin 1 of the present embodiment is configured so that the excrement and the like absorbed at the intersection of the center line XX of the absorbent body 10 and the wing adhesive portion center line WW The guiding portion 14 is diffused in the longitudinal direction rather than in the width direction. A value ((T / 2) / S) obtained by dividing half (T / 2) of the length T in the longitudinal direction of the excrement present region q by the length S in the width direction is the front end of the front compressed portion 26a. By making the distance H from 26ae to the wing adhesive part center line WW equal to or greater than the value (H / K) obtained by dividing the wing adhesive part center line WW by the length K in the width direction of the absorbent body 10 ( (T / 2) / S ≧ H / K) In any state, the excreta present region q is accommodated inside the absorber 10, and the excrement is diffused over a wider range of the absorber 10 and absorbed. The risk of excrement leaking to the outside in the width direction of the body 10 is reduced. That is, the excrement can be induced so that the excrement existing region q reaches the front pressing portion 26a before reaching the lateral end 10e of the absorber 10, and the absorber is more than the case of the absorber 101 of the napkin 100. Excrement etc. can be absorbed in 10 wider range.
 また、図11Dは、ナプキン1の最大排泄物存在領域qmを示す模式図である。図11Dに示すように、拡散した液体が前側圧搾部26aの前側の端26aeに到達したときの排泄物存在領域qを最大排泄物存在領域qmといい、排泄物存在領域qmの長手方向の長さTmの半分(Tm/2)を、幅方向の長さSmで除した値((Tm/2)/Sm)が、前側圧搾部26aの前側の端26aeからウィング粘着部中心線W-Wまでの距離Hを、ウィング粘着部中心線W-Wにおける吸収体10の幅方向の長さKで除した値(H/K)以上となる((Tm/2)/Sm≧H/K)。そのため、最大排泄物存在領域qmの状態まで排泄物が広がった状態においても、吸収体10の横端10eから排泄物が漏れる恐れを軽減することができる。 Further, FIG. 11D is a schematic diagram showing the maximum excreta existing region qm of the napkin 1. As shown in FIG. 11D, the excrement existence region q when the diffused liquid reaches the front end 26ae of the front pressing portion 26a is referred to as a maximum excretion existence region qm, and the length of the excrement existence region qm in the longitudinal direction. A value obtained by dividing half of the length Tm (Tm / 2) by the length Sm in the width direction ((Tm / 2) / Sm) is a wing adhesive portion center line WW from the front end 26ae of the front compressed portion 26a. Is equal to or greater than the value (H / K) obtained by dividing the distance H by the length K in the width direction of the absorbent body 10 at the wing adhesive portion center line WW ((Tm / 2) / Sm ≧ H / K). . Therefore, even when the excrement has spread to the state of the maximum excrement existence region qm, the risk of excretion leaking from the lateral end 10e of the absorber 10 can be reduced.
 なお、最大排泄物存在領域qmは、長手方向においてウィング粘着部中心線W-Wに対して非対称な形状である。つまり、最大排泄物存在領域qmの前側の端(前側圧搾部26aの前側の端26ae)からウィング粘着部中心線W-Wまでの距離より、ウィング粘着部中心線W-Wから最大排泄物存在領域qmの後側の端までの距離の方が長い。これは、吸収体10の後側領域に設けられた各線状圧搾部28b、29bが、長手方向への排泄物の拡散を促しているからである。ナプキン1は、前側領域R1より後側領域R3の方が長いため、各線状圧搾部28b、29bによって、より後側領域への排泄物の拡散を促すことができ、最大排泄物存在領域qmをより広い領域にすることができる。 It should be noted that the maximum excreta present region qm has an asymmetric shape with respect to the wing adhesive portion center line WW in the longitudinal direction. That is, from the distance from the front end (front end 26ae of the front compressed portion 26a) to the wing adhesive portion center line WW to the maximum excrement presence region qm, the maximum excrement exists from the wing adhesive portion center line WW. The distance to the rear end of the region qm is longer. This is because each linear pressing part 28b, 29b provided in the rear region of the absorbent body 10 promotes the diffusion of excrement in the longitudinal direction. Since the napkin 1 is longer in the rear region R3 than in the front region R1, each linear squeezed portion 28b, 29b can promote the diffusion of the excrement to the rear region, and the maximum excrement existence region qm A wider area can be obtained.
 さらに、吸収体10の中央領域R2に、長手方向に沿った一方側線状圧搾部27aと他方側線状圧搾部27aが設けられており、各線状圧搾部27aの幅方向の外側の端は外端27aeである。排泄物存在領域qの長手方向の長さTの半分を、排泄物存在領域qの幅方向の長さSで除した値((T/2)/S)が、前側圧搾部26aの前側の端26aeからウィング粘着部中心線W-Wまでの距離Hを、ウィング粘着部中心線W-Wにおける一方側の外端27aeと他方側の外端27aeとの距離Jで除した値以上((T/2)/S≧H/J)とすることが好ましい。これにより、排泄物存在領域qが、各線状圧搾部27aの外端27aeに達すると同時に又は外端27aeに達するより前に、前側圧搾部26aに達するように排泄物を誘導することができる。 Furthermore, in the center area | region R2 of the absorber 10, the one side linear pressing part 27a and the other side linear pressing part 27a along a longitudinal direction are provided, and the outer end of the width direction of each linear pressing part 27a is an outer end. 27ae. A value ((T / 2) / S) obtained by dividing half of the length T in the longitudinal direction of the excrement present area q by the length S in the width direction of the excrement present area q is the front side of the front compressed portion 26a. More than or equal to the value obtained by dividing the distance H from the end 26ae to the wing adhesive portion center line WW by the distance J between the outer end 27ae on one side and the outer end 27ae on the other side of the wing adhesive portion center line WW (( T / 2) / S ≧ H / J) is preferable. Thereby, excrement can be induced | guided | derived so that the excretion presence area | region q may reach the front side compression part 26a simultaneously with reaching the outer end 27ae of each linear pressing part 27a, or before reaching the outer end 27ae.
 さらに、ナプキン1は、肌面側を内側にして折り畳むための、幅方向に沿った複数の折り畳み部Ff、Fbを有しており、吸収体10は、吸収体10の後側領域に、厚さ方向に凹み、長手方向と交差する後側圧搾部28aを有しており、前側圧搾部26aが、ウィング粘着部31に最も近い前側折り畳み部Ffより前側に設けられ、かつ、ウィング粘着部31に最も近い後側折り畳み部Fbより後側に設けられていることが好ましい。前側圧搾部26a及び後側圧搾部28aは排泄物を幅方向(as26、as28)に誘導するため、前側圧搾部26a及び後側圧搾部28aが、吸収体10の前端10et及び後端10ebより外側に排泄物等が漏れる恐れを軽減しており、前側圧搾部26aを前側折り畳み部Ffより前側に設け、後側圧搾部28aを後側折り畳み部Fbより後側に設けることで、前側圧搾部26aと後側圧搾部28aの間に設けられた中央誘導部14の長さを確保することができ、吸収体10のより広い範囲で排泄物等を吸収させることができる。 Furthermore, the napkin 1 has a plurality of folding portions Ff and Fb along the width direction for folding with the skin surface side inward, and the absorbent body 10 is thicker in the rear region of the absorbent body 10. It has a rear squeezing part 28a that is recessed in the vertical direction and intersects the longitudinal direction, and the front squeezing part 26a is provided in front of the front folding part Ff closest to the wing adhesive part 31, and the wing adhesive part 31 It is preferable that it is provided in the rear side from the rear side folding part Fb nearest to. Since the front pressing part 26a and the rear pressing part 28a induce excrement in the width direction (as26, as28), the front pressing part 26a and the rear pressing part 28a are outside the front end 10et and the rear end 10eb of the absorbent body 10. This reduces the risk of excrement etc. leaking to the front, and the front pressing part 26a is provided in front of the front folding part Ff, and the rear pressing part 28a is provided in the rear side of the rear folding part Fb, so that the front pressing part 26a is provided. And the length of the center guide | induction part 14 provided between the back side compression parts 28a can be ensured, and excrement etc. can be absorbed in the wider range of the absorber 10. FIG.
 さらに、吸収体10は、長手方向における吸収体10の後側領域に、厚さ方向に凹み、長手方向に沿った、線状の線状圧搾部29bを有していることが好ましい。この排泄物存在領域Q(q)が線状圧搾部29bにまで到達すると、線状圧搾部29bに沿った後側(ab29)へ排泄物の拡散を促すことができるため、ナプキン1のように前側より後側の方が長い場合においては、より後側へ排泄物を拡散させた方が吸収体10のより広い範囲で排泄物を吸収させることができる。なお、本実施形態においては、線状圧搾部29bより幅方向外側に、長手方向における吸収体10の後側領域に、厚さ方向に凹み、長手方向に沿った、線状の線状圧搾部28bも有している。この線状圧搾部28bについても、排泄物を後側(ab28)へより拡散することができるため、排泄物存在領域Q(q)が線状圧搾部28bにまで達した場合には、より長手方向への拡散を促して、吸収体10の横端10eより外側に排泄物が漏れてしまう恐れを軽減することができる。 Furthermore, it is preferable that the absorbent body 10 has a linear linear squeezed portion 29b that is recessed in the thickness direction and along the longitudinal direction in the rear region of the absorbent body 10 in the longitudinal direction. When the excrement present area Q (q) reaches the linear pressing part 29b, the excretion can be promoted to the rear side (ab29) along the linear pressing part 29b. In the case where the rear side is longer than the front side, excrement can be absorbed in a wider range of the absorbent body 10 if the excrement is diffused further to the rear side. In addition, in this embodiment, it dents in the thickness direction in the back side area | region of the absorber 10 in a longitudinal direction on the width direction outer side from the linear pressing part 29b, and the linear linear pressing part along the longitudinal direction 28b. Since the excrement can be further diffused to the rear side (ab28) with respect to the linear pressing part 28b, the excretion existing region Q (q) is more longitudinal when reaching the linear pressing part 28b. The diffusion in the direction can be promoted, and the risk of excrement leaking outside the lateral end 10e of the absorbent body 10 can be reduced.
 さらに、吸収体10は、長手方向における吸収体10の後側領域に、厚さ方向に凹み、長手方向と交差する後側圧搾部28a、29aを有しており、各線状圧搾部28b、29bは、長手方向における、ウィング粘着部31の後側の端から最も後側に位置する後側圧搾部28aの最も後側の端28aeまでの間に位置していることが好ましい。これにより各線状圧搾部28b、29bによって後側(ab28、ab29)に促された排泄物が、後側圧搾部28aまで達すると幅方向の外側(as28)へ促されるため、後側圧搾部28aより長手方向の外側に排泄物が漏れる恐れを軽減することができる。 Furthermore, the absorbent body 10 has rear compressed portions 28a and 29a that are recessed in the thickness direction and intersect the longitudinal direction in the rear region of the absorbent body 10 in the longitudinal direction, and each linear compressed portion 28b and 29b. Is preferably located between the rear end of the wing adhesive portion 31 and the rearmost end 28ae of the rear compressed portion 28a located on the rearmost side in the longitudinal direction. As a result, the excrement urged to the rear side (ab28, ab29) by the linear squeezing parts 28b, 29b is urged to the outside in the width direction (as28) when reaching the rear squeezing part 28a. The risk of excrement leaking to the outside in the longitudinal direction can be reduced.
 さらに、ナプキン1は、一対の線状圧搾部29bと、線状圧搾部29bの長手方向の各端と接続された後側圧搾部29aを有する圧搾部29と、一対の線状圧搾部28bと、線状圧搾部28bと長手方向の各端と接続された後側圧搾部28aを有する圧搾部28を備えており、長手方向及び幅方向において、圧搾部29は、圧搾部28より内側に位置していることが好ましい。これにより、線状圧搾部29bによって、排泄物を後側(ab29)に誘導することができ、後側圧搾部29aまで排泄物が広がった場合においても、圧搾部29より外側に位置する線状圧搾部28bによって、吸収体10の幅方向の外側に排泄物が漏れてしまう恐れを軽減することができる。また、後側圧搾部29aによって、排泄物を幅方向の外側(as29)に移動させることができる。さらに、後側圧搾部29aより後側に排泄物が広がった場合でも、圧搾部29より外側に位置する圧搾部28の後側圧搾部28aによって、吸収体10の後側に排泄物が漏れてしまう恐れを軽減することができる。 Further, the napkin 1 includes a pair of linear pressing portions 29b, a pressing portion 29 having a rear pressing portion 29a connected to each longitudinal end of the linear pressing portion 29b, and a pair of linear pressing portions 28b. The pressing part 28 has a pressing part 28 having a linear pressing part 28b and a rear pressing part 28a connected to each end in the longitudinal direction, and the pressing part 29 is located inside the pressing part 28 in the longitudinal direction and the width direction. It is preferable. Thereby, the excrement can be guided to the rear side (ab29) by the linear pressing part 29b, and even when the excrement spreads to the rear pressing part 29a, the linear shape located outside the pressing part 29. The pressing part 28b can reduce the risk of excrement leaking outside the absorbent body 10 in the width direction. Moreover, excrement can be moved to the outer side (as29) of the width direction by the rear side pressing part 29a. Furthermore, even when excrement spreads behind the rear pressing part 29a, excrement leaks to the rear side of the absorbent body 10 by the rear pressing part 28a located outside the pressing part 29. Can reduce the fear.
 さらに、ナプキン1の中央誘導部14は、吸収体10の前側の端10etから後側の端10ebまで設けられており、中央誘導部14は、前側圧搾部26a及び後側圧搾部28aと交差していることが好ましい。これによって、中央誘導部14によって排泄物を長手方向(af14、ab14)へ拡散させつつ、中央誘導部14と、それぞれ前側圧搾部26a及び後側圧搾部28aと交差した部分で、前側圧搾部26a及び後側圧搾部28aが幅方向の外側(as26、as28)へ排泄物の誘導を促すことができるので、吸収体10の長手方向の外側に排泄物が漏れることを軽減することができる。つまり、ナプキン1の後側領域R3においては、排泄物を長手方向へ促すことができる一対の線状圧搾部28bと一対の線状圧搾部29bをそれぞれ有し、排泄物を幅方向へ促す傾向が強い後側圧搾部28aと後側圧搾部29aを有しているため、各線状圧搾部28b、29bによって排泄物が長手方向の外側へ促された場合においても、後側圧搾部28aが実質的に長手方向への拡散を堰き止める役割を担い、吸収体10の後側の端10ebの外側に排泄物が漏れてしまう恐れを軽減することができる。 Further, the central guiding portion 14 of the napkin 1 is provided from the front end 10et to the rear end 10eb of the absorber 10, and the central guiding portion 14 intersects with the front pressing portion 26a and the rear pressing portion 28a. It is preferable. Thus, while the excrement is diffused in the longitudinal direction (af14, ab14) by the central guiding portion 14, the central pressing portion 26 and the front pressing portion 26a are respectively crossed with the front pressing portion 26a and the rear pressing portion 28a. And since the back side compression part 28a can accelerate | stimulate induction | guidance | derivation of excrement to the outer side (as26, as28) of the width direction, it can reduce that excrement leaks to the outer side of the longitudinal direction of the absorber 10. FIG. That is, the rear region R3 of the napkin 1 has a pair of linear pressing portions 28b and a pair of linear pressing portions 29b that can promote excretion in the longitudinal direction, and tends to promote excretion in the width direction. However, even when excrement is urged to the outside in the longitudinal direction by the respective linear compressed parts 28b and 29b, the rear compressed part 28a is substantially the same because the rear compressed part 28a and the rear compressed part 29a are included. In particular, it plays a role of blocking diffusion in the longitudinal direction, and the risk of excrement leaking outside the rear end 10eb of the absorber 10 can be reduced.
 さらに、図6Dに示すように、中央誘導部14の中央部ccにおける厚さ方向の中央位置は、吸収体点状圧搾部15の中央部bcにおける厚さ方向の中央位置より、肌側に位置していることが好ましい。これによって、吸収体10が中央誘導部14を基点に肌側に折り曲がり、使用者の膣口等の排泄口に当接されるため、まず、中央誘導部14で吸収した排泄物等を肌側から非肌側に移動させて、点状圧搾部15へ移動させる。これによって、肌に当接する部分に排泄物が滞留することを軽減して、肌触りを向上させることができる。 Furthermore, as shown to FIG. 6D, the center position of the thickness direction in the center part cc of the center induction | guidance | derivation part 14 is located in the skin side rather than the center position of the thickness direction in the center part bc of the absorber dotted | punctate pressing part 15. It is preferable. As a result, the absorbent body 10 bends to the skin side with the central guiding portion 14 as a base point and comes into contact with the excretory opening such as the user's vagina mouth. Therefore, first, the excrement absorbed by the central guiding portion 14 is removed from the skin. It is moved from the side to the non-skin side and moved to the point-like compressed part 15. As a result, it is possible to reduce the retention of excrement in the portion in contact with the skin and improve the touch.
 さらに、図6Dに示すように、中央誘導部14の領域cと、中央誘導部14と幅方向に隣接する吸収体点状圧搾部15の領域bとの間に、液体吸収性繊維の密度が、中央誘導部14の中央部cc及び吸収体点状圧搾部15の中央部bcより低い領域aが設けられていることが好ましい。つまり、圧搾加工により液体吸収性繊維の密度をより高くした領域cと領域bとの間に、圧搾加工が施されておらず、液体吸収性繊維の密度が比較的低い領域aが設けられていることで、液体吸収性繊維の低い領域aでは、中央誘導部14で吸収し、移動された排泄物を貯留することができ、領域aで貯留しきれなくなった排泄物を幅方向に隣接する点状圧搾部に吸収させるという流路の役割を担うことができる。 Furthermore, as shown to FIG. 6D, the density of a liquid absorptive fiber is between the area | region c of the center induction | guidance | derivation part 14, and the area | region b of the absorber dotted | punctate pressing part 15 adjacent to the center induction | guidance | derivation part 14 and the width direction. It is preferable that a region a lower than the central portion cc of the central guiding portion 14 and the central portion bc of the absorber point-like compressed portion 15 is provided. That is, between the area | region c and the area | region b which made the density of the liquid absorptive fiber higher by the squeezing process, the area | region a where the density of the liquid absorptive fiber is comparatively low is not provided. Therefore, in the region a where the liquid absorbent fiber is low, the excrement absorbed and moved by the central guiding portion 14 can be stored, and the excrement that cannot be stored in the region a is adjacent in the width direction. It can play the role of a flow path that is absorbed by the point-like compressed portion.

 以上、本発明の実施形態について説明したが、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。
=== Other Embodiments ===
As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof.
 上記の実施形態では、吸収体10の前端10etから後端10ebまで中央誘導部14を設けたが、必ずしもこれに限られない。前側圧搾部26aの前側の端26atから後側圧搾部28の後側の端28abまでの間に中央誘導部14を設けるものとしても良い。この場合においても、長手方向において、前側は少なくとも前側圧搾部26aまで、後側は少なくとも後側圧搾部28aまで中央誘導部14が排泄物を長手方向に誘導することができるため、長手方向に拡散することを可能にしつつ、前側圧搾部26a及び後側圧搾部28aより長手方向の外側には、排泄物を誘導しづらくなるため、長手方向の外側に排泄物が漏れる恐れを軽減することができる。ただし、排泄物の量が多い場合には、吸収体10の横端10eの外側に排泄物が漏れてしまう恐れがあるため、そのような場合には、中央誘導部14を吸収体10の全域に亘って設けることで、前側圧搾部26及び後側圧搾部28より長手方向の外側に排泄物を誘導して、排泄物が漏れる恐れを軽減することができる。 In the above embodiment, the central guiding portion 14 is provided from the front end 10et to the rear end 10eb of the absorber 10, but the present invention is not necessarily limited thereto. The central guide portion 14 may be provided between the front end 26at of the front pressing portion 26a and the rear end 28ab of the rear pressing portion 28. Even in this case, in the longitudinal direction, the front side is at least up to the front side compressed part 26a, and the rear side is at least up to the rear side compressed part 28a. While being able to do, since it becomes difficult to guide excrement to the outer side of a longitudinal direction from the front side compression part 26a and the rear side compression part 28a, the possibility that excrement leaks to the outer side of a longitudinal direction can be reduced. . However, when there is a large amount of excrement, there is a risk that excrement may leak outside the lateral end 10e of the absorber 10. In such a case, the central guiding portion 14 is placed over the entire area of the absorber 10. By providing over, the excrement can be induced | guided | derived to the outer side of a longitudinal direction from the front side pressing part 26 and the rear side pressing part 28, and the possibility that excrement leaks can be reduced.
 また、上記の実施形態では、後側領域R3において、圧搾部28と圧搾部29の2つを設けたが、これに限られない。圧搾部28だけ設けてもよいし、圧搾部28、29以外に更に他の圧搾部を設けてもよい。排泄物存在領域Q(q)の長手方向の長さ及び幅方向の長さを、中央誘導部14及び圧搾部28、29等の圧搾部によって任意に調整することができる。 Moreover, in said embodiment, although 2 parts of the pressing part 28 and the pressing part 29 were provided in back side area | region R3, it is not restricted to this. Only the pressing part 28 may be provided, and other pressing parts may be provided in addition to the pressing parts 28 and 29. The length in the longitudinal direction and the length in the width direction of the excrement existence region Q (q) can be arbitrarily adjusted by the central guiding portion 14 and the pressing portions such as the pressing portions 28 and 29.
 上記の実施形態では、圧搾部25や吸収体10に複数の吸収体点状圧搾部15を設けたが、必ずしも設ける必要はない。また、中央誘導部14や圧搾部26、27、28、29等についても圧搾加工を行うことによって形成したが、これに限られない。目付量を変化させたり、溝部を形成したりしてもよい。中央誘導部14、圧搾部25、26、27、28、吸収体点状圧搾部15等は、排泄物存在領域Q(q)の範囲に対応して、適宜調整することができる。 In the above embodiment, the squeezing part 25 and the absorbent body 10 are provided with the plurality of absorbent point squeezing parts 15, but it is not always necessary to provide them. Moreover, although formed about the center induction | guidance | derivation part 14, pressing part 26,27,28,29 etc. by performing a pressing process, it is not restricted to this. The basis weight may be changed or a groove may be formed. The center guide | induction part 14, the pressing parts 25, 26, 27, 28, the absorber dotted | punctate pressing part 15 grade | etc., Can be suitably adjusted corresponding to the range of the excretion presence area | region Q (q).
