Description

本発明は、軽失禁パッドや生理用ナプキン、使い捨ておむつ等の吸収性物品に関する。 The present invention relates to absorbent articles such as light incontinence pads, sanitary napkins and disposable diapers.

軽失禁パッドや生理用ナプキン、使い捨ておむつ等の吸収性物品は、着用者の股間部に接触しながら長時間にわたって着用されるものであるため、着用者に違和感や不快感などを生じさせないように、着用者から排出された***物を素早く吸収することや着用者の身体へのフィット性に優れることなどが求められている。 Absorbent items such as light incontinence pads, sanitary napkins, and disposable diapers are worn for a long time while in contact with the wearer's crotch area, so that the wearer does not feel uncomfortable or uncomfortable. , It is required to quickly absorb excrement discharged from the wearer and to have an excellent fit to the wearer's body.

そして、中には、液の吸収性やフィット性を向上させるために、吸収体ないし吸収コアに所定の方向に延びる溝部などを形成した吸収性物品が知られている。
例えば、特許文献１には、吸収性コアを有する吸収性物品であって、前記吸収性コアが中央域とその幅方向の両側部に位置する側部域とを備えており、前記中央域と前記側部域とが前記吸収性コアの長手方向に延びる側方溝部によって少なくとも股下部において離間し、さらに前記側部域が前記吸収性コアの長手方向と交差する方向に延びる複数の交差溝部を有し、各交差溝部が、それらの仮想延長線が前記吸収性コアの中央部を向くような角度で該吸収性コアの長手方向と交差しているという特定の構成を備えた、吸収性物品が開示されている。
この特許文献１に開示された吸収性物品は、着用時に側方溝部や交差溝部が吸収性コアの屈曲誘導部として作用するので、側部域が柔軟に変形して着用者の身体とのフィット性が向上するとされている。 And, among them, an absorbent article in which a groove extending in a predetermined direction is formed in an absorber or an absorption core in order to improve the absorbency and fit of a liquid is known.
For example, Patent Document 1 provides an absorbent article having an absorbent core, wherein the absorbent core includes a central region and side regions located on both sides in the width direction thereof, and the central region and the central region thereof. A plurality of intersecting grooves extending in a direction in which the lateral region is separated from the lateral region by a lateral groove extending in the longitudinal direction of the absorbent core at least in the inseam, and the lateral region further intersects the longitudinal direction of the absorbent core. Absorbent article having a particular configuration in which each cross groove intersects the longitudinal direction of the absorbent core at an angle such that their virtual extensions face the central portion of the absorbent core. Is disclosed.
In the absorbent article disclosed in Patent Document 1, since the lateral groove portion and the cross groove portion act as the bending guide portion of the absorbent core when worn, the lateral region is flexibly deformed to fit the wearer's body. It is said that the sex will improve.

しかしながら、このような特許文献１に開示された吸収性物品では、着用者の歩行時などの動作時におけるフィット性については考慮されておらず、また、着用者の脚周りに近い交差溝部が吸収体の幅方向端縁まで延びていないため、着用者が歩行などの動作を行ったときに（具体的には、吸収性物品に対し、長手方向を軸として左右交互に捩じれる方向の力が加わるような動作を行ったときに）、吸収体、ひいては吸収性物品が着用者の動作に追従して変形しきれず、着用者に違和感を生じさせる恐れがあった。 However, in such an absorbent article disclosed in Patent Document 1, the fit during movement such as walking of the wearer is not considered, and the cross groove portion near the wearer's leg absorbs. Since it does not extend to the widthwise edge of the body, when the wearer performs an action such as walking (specifically, a force in a direction in which the absorbent article is twisted alternately left and right with respect to the longitudinal direction is applied. The absorber, and thus the absorbent article, could not be completely deformed in accordance with the wearer's movement (when performing such an action), which may cause a sense of discomfort to the wearer.

そこで、本発明は、歩行などの動作時においても着用者に違和感を生じさせにくく、フィット性に優れた吸収性物品を提供することを目的とする。 Therefore, an object of the present invention is to provide an absorbent article having excellent fit, which does not easily cause discomfort to the wearer even during movements such as walking.

本発明の一態様（態様１）は、肌対向面を形成する表面シートと、非肌対向面を形成する裏面シートと、これらのシートの間に位置する吸収体とを備えた、長手方向、幅方向及び厚さ方向を有する吸収性物品であって、
前記吸収体は、平面視にて、
前記長手方向に延びる幅方向中心線を挟んで対称となるように配置された、少なくとも一対の折曲げ誘導部と、
前記一対の折曲げ誘導部の幅方向内方側に位置し且つ前記幅方向中心線を挟んで対称となるように配置された、前記長手方向に延びる少なくとも一対の凹部と、を有しており、
前記一対の折曲げ誘導部の各々は、前記吸収体の幅方向端縁から幅方向内方側に向かって延び、且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びていることを特徴とする、前記吸収性物品である。 One aspect (aspect 1) of the present invention is a longitudinal direction, comprising a front surface sheet forming a skin facing surface, a back surface sheet forming a non-skin facing surface, and an absorber located between these sheets. An absorbent article having a width direction and a thickness direction.
The absorber is viewed in a plan view.
At least a pair of bending guides arranged symmetrically with respect to the widthwise center line extending in the longitudinal direction.
It has at least a pair of recesses extending in the longitudinal direction, which are located on the inner side in the width direction of the pair of bending guide portions and are arranged symmetrically with respect to the center line in the width direction. ,
Each of the pair of bending guides extends inward in the width direction from the widthwise edge of the absorber, and extends inward in the longitudinal direction as it goes inward in the width direction. The absorbent article, characterized in that it is.

本態様１の吸収性物品は、吸収体の折れ曲がり基点として機能する折曲げ誘導部が、吸収体の幅方向端縁から幅方向内方側に向かって延び、且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びているため、着用者の歩行時などの動作時においても（具体的には、吸収性物品に対し、長手方向を軸として左右交互に捩じれる方向の力が加わるような動作時においても）、吸収体、ひいては吸収性物品が着用者の動作に追従して変形しやすく（以下、このような折曲げ誘導部による作用を、単に「追従変形作用」と称する。）、着用者に違和感を生じさせにくくなっている。
さらに、本態様１の吸収性物品は、吸収体が折曲げ誘導部の幅方向内方側の位置に長手方向に延びる一対の凹部を有しているので、着用者の動作時に、上述の折曲げ誘導部を介して吸収性物品に長手方向を軸として左右交互に捩じれる方向の力が加わったとしても、長手方向に延びる一対の凹部によってその力を分散することができ、当該一対の凹部よりも幅方向内方側の部分、すなわち吸収体の幅方向中央部分を変形しにくくすることができる。
このように本態様１の吸収性物品は、上述の折曲げ誘導部による追従変形作用に加えて、吸収体の幅方向中央部分を的確に着用者の股間部に密着させることできるので、着用者の動作時においても優れたフィット性を発揮することができる。
以上より、本態様１の吸収性物品は、歩行などの動作時においても着用者に違和感を生じさせにくく、優れたフィット性を発揮することができる。 In the absorbent article of the first aspect, as the bending guide portion that functions as the bending base point of the absorber extends inward in the width direction from the widthwise edge of the absorber and toward the inward side in the width direction. Since it extends inward in the longitudinal direction, even during movements such as walking by the wearer (specifically, the direction in which the absorbent article is twisted alternately left and right with respect to the longitudinal direction). The absorber, and thus the absorbent article, is easily deformed according to the wearer's movement (even when a force is applied), and the action of such a bending guide portion is simply referred to as "following deformation action". It is less likely to cause discomfort to the wearer.
Further, in the absorbent article of the present aspect 1, since the absorber has a pair of recesses extending in the longitudinal direction at a position on the inner side in the width direction of the bending guide portion, the above-mentioned folding is performed during the operation of the wearer. Even if a force is applied to the absorbent article through the bending guide portion in a direction in which the article is twisted alternately left and right with respect to the longitudinal direction, the force can be dispersed by a pair of recesses extending in the longitudinal direction, and the pair of recesses can be dispersed. The portion on the inner side in the width direction, that is, the central portion in the width direction of the absorber can be made less likely to be deformed.
As described above, in the absorbent article of the present aspect 1, in addition to the follow-up deformation action by the bending guide portion described above, the central portion in the width direction of the absorber can be accurately brought into close contact with the crotch portion of the wearer. It is possible to demonstrate excellent fit even during the operation of.
From the above, the absorbent article of the first aspect is less likely to cause discomfort to the wearer even during movements such as walking, and can exhibit excellent fit.

また、本発明の別の態様（態様２）では、上記態様１の吸収性物品において、前記少なくとも一対の折曲げ誘導部は、前記幅方向に延びる長手方向中心線に対して、前記長手方向の一方側に位置する一対の折曲げ誘導部と、前記長手方向の他方側に位置する一対の折曲げ誘導部と、を含み、
前記長手方向の一方側に位置する一対の折曲げ誘導部と、前記長手方向の他方側に位置する一対の折曲げ誘導部とは、前記長手方向中心線を挟んで対称となるように配置されていることを特徴とする。 Further, in another aspect (aspect 2) of the present invention, in the absorbent article of the above aspect 1, the at least pair of bending guide portions is in the longitudinal direction with respect to the longitudinal center line extending in the width direction. A pair of bending guides located on one side and a pair of bending guides located on the other side in the longitudinal direction are included.
The pair of bending guides located on one side in the longitudinal direction and the pair of bending guides located on the other side in the longitudinal direction are arranged so as to be symmetrical with respect to the center line in the longitudinal direction. It is characterized by being.

本態様２の吸収性物品は、長手方向の一方側に位置する一対の折曲げ誘導部と、長手方向の他方側に位置する一対の折曲げ誘導部とが長手方向中心線を挟んで対称となるように配置されているため、着用者の動作時に、吸収性物品の長手方向の広範囲にわたって上述の折曲げ誘導部による追従変形作用を発揮することができる。 In the absorbent article of the second aspect, the pair of bending guides located on one side in the longitudinal direction and the pair of bending guides located on the other side in the longitudinal direction are symmetrical with respect to the center line in the longitudinal direction. Therefore, during the movement of the wearer, the follow-up deformation action by the above-mentioned bending guide portion can be exerted over a wide range in the longitudinal direction of the absorbent article.

本発明の更に別の態様（態様３）では、上記態様１又は２の吸収性物品において、前記少なくとも一対の折曲げ誘導部は、前記幅方向中心線に対して前記幅方向の一方側に位置する折曲げ誘導部の仮想延長線と、前記幅方向中心線に対して前記幅方向の他方側に位置する折曲げ誘導部の仮想延長線とが同一直線上に重ならないように配置されていることを特徴とする。 In yet another aspect of the present invention (aspect 3), in the absorbent article of aspect 1 or 2, the at least pair of bending guides are located on one side of the width direction with respect to the width direction center line. The virtual extension line of the bending guide portion and the virtual extension line of the bending guidance portion located on the other side in the width direction with respect to the center line in the width direction are arranged so as not to overlap on the same straight line. It is characterized by that.

本態様３の吸収性物品は、少なくとも一対の折曲げ誘導部が、幅方向の一方側に位置する折曲げ誘導部の仮想延長線と、前記幅方向中心線に対して前記幅方向の他方側に位置する折曲げ誘導部の仮想延長線とが同一直線上に重ならないように配置されているため、それぞれの折曲げ誘導部ごとに折れ曲がり基点を形成することができ、吸収体をより多様な形状に変形しやすくすることができる上、仮に、着用者の動作時に上述の捩じれる方向の力が折曲げ誘導部を介して吸収体の幅方向中央部分に及んだとしても、当該幅方向中央部分においては折れ曲がり基点が形成されにくく、当該吸収体の幅方向中央部分の折れ曲がりをより生じにくくすることができる。 In the absorbent article of the third aspect, at least a pair of bending guide portions are located on one side in the width direction as a virtual extension line of the bending guidance portion and the other side in the width direction with respect to the center line in the width direction. Since the virtual extension lines of the bending guides located at are arranged so as not to overlap on the same straight line, a bending base point can be formed for each bending guide, and the absorbers are more diverse. In addition to being able to easily deform into a shape, even if the above-mentioned twisting force is applied to the central portion in the width direction of the absorber via the bending guide portion during the movement of the wearer, the width direction is concerned. It is difficult to form a bending base point in the central portion, and it is possible to make it more difficult for the bending in the central portion in the width direction of the absorber to occur.

本発明の更に別の態様（態様４）では、上記態様１〜３のいずれかの吸収性物品において、前記吸収体は、肌対向面側に位置する前記表面シート又は中間シートと接着層を介して接合されており、
前記接着層は、平面視にて、前記長手方向と平行な仮想線と交差する部分を有しながら、前記長手方向に延在していることを特徴とする。 In yet another aspect (aspect 4) of the present invention, in any of the absorbent articles of aspects 1 to 3, the absorber is interposed with the surface sheet or intermediate sheet located on the skin-facing surface side via an adhesive layer. Are joined together

なお、軽失禁パッド１においては、吸収体４の長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１、５２と、吸収体４の長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３、５４とは、幅方向Ｗに延びる長手方向中心線ＣＷを挟んで対称となるように配置されている。 In the light incontinence pad 1, a pair of bending guide portions 51 and 52 located on one side of the absorber 4 in the longitudinal direction L and a pair of bending guiding portions 51 and 52 located on the other side of the absorber 4 in the longitudinal direction L. The guide portions 53 and 54 are arranged so as to be symmetrical with respect to the longitudinal center line C W extending in the width direction W.

上述の軽失禁パッド１は、図５に示すように吸収体４の折れ曲がり基点として機能する少なくとも一対の折曲げ誘導部５１、５２が、吸収体４の幅方向端縁４Ｗ１，４Ｗ２から幅方向内方側に向かって延び、且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びているため、着用者の歩行時などの動作時においても（具体的には、軽失禁パッド１に対し、長手方向Ｌを軸として左右交互に捩じれる方向の力が加わるような動作時においても）、吸収体４、ひいては軽失禁パッド１が着用者の動作に追従して変形しやすく（すなわち、追従変形作用を有しており）、着用者に違和感を生じさせにくくなっている。
さらに、軽失禁パッド１は、吸収体４が折曲げ誘導部５１、５２の幅方向内方側の位置に長手方向Ｌに延びる一対の凹部６１、６２を有しているので、着用者の動作時に、上述の少なくとも一対の折曲げ誘導部５１、５２を介して軽失禁パッド１に長手方向Ｌを軸として左右交互に捩じれる方向の力が加わったとしても、長手方向Ｌに延びる一対の凹部６１、６２によってその力を分散することができ、当該一対の凹部６１，６２よりも幅方向内方側の部分、すなわち吸収体４の幅方向中央部分を変形しにくくすることができる。
このように軽失禁パッド１は、上述の少なくとも一対の折曲げ誘導部５１，５２による追従変形作用に加えて、吸収体４の幅方向中央部分を的確に着用者の股間部に密着させることできるので、着用者の動作時においても優れたフィット性を発揮することができる。
したがって、軽失禁パッド１は、歩行などの動作時においても着用者に違和感を生じさせにくく、優れたフィット性を発揮することができる。 In the above-mentioned light incontinence pad 1, at least a pair of bending guide portions 51, 52 functioning as a bending base point of the absorber 4 as shown in FIG. 5 have widths from the widthwise end edges 4W 1 , 4W 2 of the absorber 4. Since it extends inward in the direction and extends inward in the longitudinal direction toward the inward side in the width direction, it extends toward the inward side in the longitudinal direction even during movements such as when the wearer is walking (specifically, when the wearer is walking). The absorber 4 and, by extension, the light incontinence pad 1 are deformed according to the wearer's movements (even when a force is applied to the light incontinence pad 1 in the direction of alternately twisting left and right with respect to the longitudinal direction L). It is easy to do (that is, it has a follow-up deformation action), and it is difficult for the wearer to feel uncomfortable.
Further, the light incontinence pad 1 has a pair of recesses 61 and 62 extending in the longitudinal direction L at positions on the inner side in the width direction of the bending guide portions 51 and 52 in the absorber 4, so that the wearer can operate the pad 1. Occasionally, even if a force is applied to the light incontinence pad 1 in the direction of alternately twisting left and right with respect to the longitudinal direction L via at least the pair of bending guide portions 51 and 52 described above, a pair of recesses extending in the longitudinal direction L. The force can be dispersed by the 61 and 62, and the portion on the inner side in the width direction of the pair of recesses 61 and 62, that is, the central portion in the width direction of the absorber 4 can be made less likely to be deformed.
As described above, the light incontinence pad 1 can accurately bring the central portion of the absorber 4 in the width direction into close contact with the crotch portion of the wearer, in addition to the follow-up deformation action of at least the pair of bending guide portions 51 and 52 described above. Therefore, excellent fit can be exhibited even when the wearer is in motion.
Therefore, the light incontinence pad 1 is less likely to cause discomfort to the wearer even during movements such as walking, and can exhibit excellent fit.

ここで、本明細書において、長手方向Ｌに延びる幅方向中心線ＣＬを挟んで対称とは、幅方向中心線ＣＬを対称軸として線対称であることを意味する。なお、幅方向Ｗに延びる長手方向中心線ＣＷを挟んで対称も同様である。 In the present specification, the symmetrical across the width direction center line C L extending in the longitudinal direction L, which means that it is axisymmetrical width direction center line C L as a symmetrical axis. The same applies to the symmetry with the longitudinal center line C W extending in the width direction W in between.

なお、上述の軽失禁パッド１においては、図１に示すように、幅方向中心線ＣＬを挟んで対称となるように長手方向Ｌに延びる一対の圧搾部Ｅ１、Ｅ２と、当該一対の圧搾部Ｅ１、Ｅ２の間に位置し且つ長手方向中心線ＣＷを挟んで対称となるように円弧状に幅方向Ｗに延びる一対の圧搾部Ｅ３、Ｅ４と、軽失禁パッド１の外周縁部に沿って連続的に延びるラウンドシール部Ｒｓと、を更に有している。上述の軽失禁パッド１においては、一対の圧搾部Ｅ１、Ｅ２は、図１に示すように、平面視にて上記一対の凹部６１、６２と重複する位置及び形状で形成されている。 In the light incontinence pad 1 described above, as shown in FIG. 1, a pair of compression portions E 1, E 2 extending in the longitudinal direction L so as to be symmetrical with respect to the width direction center line C L, the pair squeeze portion E 1, E located between 2 and longitudinal center line C W across the extending in the width direction W in a circular arc shape to be symmetrical pair of compression portions E 3, and E 4, light incontinence pad It further has a round seal portion R s that extends continuously along the outer peripheral edge portion of 1. In the above-mentioned light incontinence pad 1, the pair of squeezed portions E 1 and E 2 are formed at positions and shapes overlapping the pair of recesses 61 and 62 in a plan view, as shown in FIG.

上述の圧搾部Ｅ１〜Ｅ４は、図３に示すように、表面シート２の肌対向面側の表面から裏面シート３に向かって厚さ方向Ｔに窪むように形成されており、エンボスなどの加工手段によって、表面シート２、肌対向面側吸収層７及び吸収体４が肌対向面側から非肌対向面側に向かって厚さ方向Ｔに圧搾されることにより形成されている。 As shown in FIG. 3, the above-mentioned squeezed portions E 1 to E 4 are formed so as to be recessed in the thickness direction T from the surface of the front surface sheet 2 on the skin-facing surface side toward the back surface sheet 3, and are embossed or the like. The surface sheet 2, the skin-facing surface side absorbing layer 7, and the absorber 4 are formed by being squeezed in the thickness direction T from the skin-facing surface side toward the non-skin-facing surface side by the processing means.

なお、これらの圧搾部Ｅ１〜Ｅ４の位置や形状は、特に制限されず、所望の液拡散性や変形誘導性、強度などに応じた任意の形状を採用することができる。そもそも軽失禁パッド１は、このような圧搾部Ｅ１〜Ｅ４を有していなくてもよい。 The positions and shapes of these squeezed portions E 1 to E 4 are not particularly limited, and any shape can be adopted according to desired liquid diffusivity, deformation inducibility, strength, and the like. In the first place, the light incontinence pad 1 does not have to have such pressing portions E 1 to E 4.

It may have a concavo-convex structure having a plurality of ridges and grooves extending in the longitudinal direction or the width direction (for example, a concavo-convex structure having a corrugated cross-sectional shape, a ridged groove structure, or the like). When the liquid-permeable sheet-like member has such a concavo-convex structure, each of the plurality of ridges in the concavo-convex structure has a hollow internal structure even if it has a solid internal structure. You may be doing it.

［吸収体］
上述の軽失禁パッド１において吸収体４は、図１に示すように、平面視にて、軽失禁パッド１の長手方向Ｌ及び幅方向Ｗの中央部を中心にして、長手方向Ｌの一方側端縁近傍から他方側端縁近傍にわたる長手方向Ｌの広範囲の領域に延在するとともに、幅方向Ｗにおいても、当該幅方向Ｗの一方側端縁近傍から他方側端縁近傍にわたる広範囲の領域に延在しており、さらに２つの長手方向端縁が長手方向外方側に向かって円弧状に突出してなる、縦長の外形形状を有している。 [Absorber]
In the above-mentioned light incontinence pad 1, as shown in FIG. 1, the absorber 4 is one side of the light incontinence pad 1 in the longitudinal direction L with the central portion in the longitudinal direction L and the width direction W as the center in a plan view. It extends over a wide area in the longitudinal direction L from the vicinity of the edge to the vicinity of the other side edge, and also in the width direction W, it extends from the vicinity of one side edge of the width direction W to the vicinity of the other side edge. It extends and has a vertically long outer shape in which two longitudinal end edges project in an arc shape toward the outward side in the longitudinal direction.

また、吸収体４は、平面視にて長手方向中央部に、他の部分と比べて幅方向長さが相対的に小さい括れ部４１を有しており、さらに、この括れ部４１において吸収体４の最小幅を有する最小幅部４２と、上記括れ部４１の長手方向外方側において吸収体４の最大幅を有する最大幅部４３、４３とを有している。 Further, the absorber 4 has a constricted portion 41 having a length in the width direction relatively smaller than other portions in the central portion in the longitudinal direction in a plan view, and further, the absorber 41 in the constricted portion 41. It has a minimum width portion 42 having the minimum width of 4 and maximum width portions 43, 43 having the maximum width of the absorber 4 on the outer side in the longitudinal direction of the constricted portion 41.

かかる吸収体４は、図３に示すように、軽失禁パッド１の厚さ方向Ｔにおいて表面シート２と裏面シート３との間（より具体的には、表面シート２の非肌対向面側に位置する肌対向面側吸収層７と裏面シート３との間）に配置されて、表面シート２及び肌対向面側吸収層７を透過してきた着用者の尿などの***液を吸収して保持し得る、所定の吸水性部材によって形成されている。 As shown in FIG. 3, the absorber 4 is located between the front surface sheet 2 and the back surface sheet 3 (more specifically, on the non-skin facing surface side of the front surface sheet 2) in the thickness direction T of the light incontinence pad 1. (Between the located skin-facing surface side absorption layer 7 and the back surface sheet 3), it absorbs and retains excrement such as urine of the wearer who has permeated the front surface sheet 2 and the skin facing surface side absorption layer 7. It is formed by a predetermined water-absorbing member.

なお、吸収体４は、肌対向面側の肌対向面側吸収層７及び非肌対向面側の裏面シート３と、それぞれホットメルト型接着剤等の任意の接着剤により接合されている。かかる接着剤によって形成される接着層Ｈについては後述する。 The absorber 4 is bonded to the skin-facing surface side absorbing layer 7 on the skin-facing surface side and the back surface sheet 3 on the non-skin-facing surface side, respectively, with an arbitrary adhesive such as a hot melt type adhesive. The adhesive layer H formed by such an adhesive will be described later.

吸収体４として用い得る吸水性部材は、着用者から排出される尿などの***液を吸収して保持し得るものであれば特に制限されず、当分野において公知の吸水性材料によって構成された吸水性部材を採用することができる。このような吸水性部材を構成する吸水性材料としては、例えば、親水性繊維や高吸収性ポリマーなどが挙げられ、更に具体的には、粉砕パルプ、コットン、レーヨン、アセテート等のセルロース系繊維；アクリル酸ナトリウムコポリマー等の高吸収性ポリマーからなる粒状物；これらを任意に組み合わせた混合物などが挙げられる。
なお、吸収体４は、親水性を有するティッシュ等のラップシートによって覆われていてもよい。 The water-absorbent member that can be used as the absorber 4 is not particularly limited as long as it can absorb and retain excrement liquid such as urine discharged from the wearer, and is made of a water-absorbent material known in the art. A water-absorbent member can be adopted. Examples of the water-absorbent material constituting such a water-absorbent member include hydrophilic fibers and highly absorbent polymers, and more specifically, cellulosic fibers such as crushed pulp, cotton, rayon, and acetate; Granules made of a highly absorbent polymer such as a sodium acrylate copolymer; a mixture of any combination of these can be mentioned.
The absorber 4 may be covered with a wrap sheet such as a hydrophilic tissue.

（折曲げ誘導部）
そして、吸収体４は、図１に示すように平面視にて、軽失禁パッド１の長手方向Ｌに延びる幅方向中心線ＣＬを挟んで対称となるように配置された、非肌対向面側の表面から肌対向面側の表面に向かって厚さ方向Ｔに窪む、相対的に低剛性の二対の折曲げ誘導部５１〜５４を有している。かかる折曲げ誘導部５１〜５４の各々は、吸収体４の幅方向端縁４Ｗ１，４Ｗ２から幅方向内方側に向かって延び、且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びている。 (Bending guide)
Then, the absorbent body 4, in plan view as shown in FIG. 1, arranged so as to be symmetrical with respect to the width direction center line C L extending in the longitudinal direction L of the light incontinence pad 1, the non-skin-facing surface It has two pairs of relatively low-rigidity bending guide portions 51 to 54 that are recessed in the thickness direction T from the side surface toward the surface facing the skin. Each of the bending guide portions 51 to 54 extends inward in the width direction from the widthwise edge 4W 1 , 4W 2 of the absorber 4, and inward in the longitudinal direction as it goes inward in the width direction. It extends toward the side.

なお、本発明において、折曲げ誘導部の配置本数は、少なくとも一対であれば上述の実施形態の軽失禁パッド１のもの（すなわち、二対）に限定されず、折曲げ誘導部は、吸収体に一対だけ形成されていても、三対以上形成されていてもよい。
このように、吸収体の折れ曲がり基点として機能する折曲げ誘導部が少なくとも一対形成され、さらに、当該一対の折曲げ誘導部が、吸収体の幅方向端縁から幅方向内方側に向かって延び且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びていると、着用者の歩行時などの動作時においても、吸収体、ひいては吸収性物品が着用者の動作に追従して変形しやすくなり、着用者に違和感を生じさせにくくすることができる。 In the present invention, the number of bending guides arranged is not limited to that of the light incontinence pad 1 of the above-described embodiment (that is, two pairs) as long as it is at least one pair, and the bending guides are absorbers. Only one pair may be formed in, or three or more pairs may be formed.
In this way, at least a pair of bending guide portions that function as bending base points of the absorber are formed, and further, the pair of bending guide portions extend inward in the width direction from the widthwise edge of the absorber. Moreover, if it extends inward in the longitudinal direction as it goes inward in the width direction, the absorber, and thus the absorbent article, follows the movement of the wearer even during movements such as walking by the wearer. Therefore, it becomes easy to be deformed, and it is possible to make it difficult for the wearer to feel uncomfortable.

また、本発明において、折曲げ誘導部の形態は、吸収体に上記のような折曲げ変形を促し得るものであれば特に限定されず、折曲げ誘導部は、吸水性材料の低坪量化によって厚さ方向に窪んでなる低坪量部のほか、例えば、貫通又は非貫通のスリット部や吸収体をエンボス等により厚さ方向に圧搾してなる圧搾溝部などの、相対的に剛性の低い低剛性部によって形成することができる。同様に、折曲げ誘導部を形成する吸収体の表面（すなわち、肌対向面側の表面及び非肌対向面側の表面）についても、上記のような折曲げ変形を促し得るものであれば特に限定されず、折曲げ誘導部は、上述の軽失禁パッド１のように吸収体の非肌対向面側の表面から肌対向面側の表面に向かって厚さ方向に窪むように形成されていても、吸収体の肌対向面側の表面から非肌対向面側の表面に向かって厚さ方向に窪むように形成されていても、あるいは吸収体の両方の表面から互いに反対側の表面に向かって厚さ方向に窪むように形成されていてもよい。 Further, in the present invention, the form of the bending guiding portion is not particularly limited as long as it can promote the bending deformation as described above in the absorber, and the bending guiding portion is formed by reducing the basis weight of the water-absorbent material. In addition to the low basis weight portion that is recessed in the thickness direction, for example, a low rigidity with relatively low rigidity such as a penetrating or non-penetrating slit portion or a squeezing groove portion formed by squeezing an absorber in the thickness direction by embossing or the like. It can be formed by a rigid portion. Similarly, the surface of the absorber forming the bending guide portion (that is, the surface on the skin facing surface side and the surface on the non-skin facing surface side) is particularly limited as long as it can promote the bending deformation as described above. The bending guide portion is not limited, and even if the bending guide portion is formed so as to be recessed in the thickness direction from the surface of the absorber on the non-skin facing surface side to the surface on the skin facing surface side like the above-mentioned light incontinence pad 1. , Even if it is formed so as to be recessed in the thickness direction from the surface of the absorber on the skin-facing surface side toward the surface on the non-skin-facing surface side, or from both surfaces of the absorber toward the surfaces opposite to each other. It may be formed so as to be recessed in the longitudinal direction.

折曲げ誘導部は、吸収体の幅方向端縁から幅方向内方側に向かって延び、且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びるものであれば、その延びる形態は特に制限されず、折曲げ誘導部は、例えば、直線状、点線状及び／又は曲線状に延びていても、単数又は複数の分岐を形成しながら延びていてもよい。 The bending guide portion extends from the widthwise edge of the absorber toward the inward side in the width direction, and extends toward the inward side in the longitudinal direction as it goes toward the inward side in the width direction. The extending form is not particularly limited, and the bending guide portion may extend, for example, in a linear shape, a dotted line shape, and / or a curved shape, or may extend while forming a single or a plurality of branches.

なお、少なくとも一対の折曲げ誘導部の配置位置は、本発明の効果を阻害しない限り特に制限されないが、着用者が吸収性物品を着用した時に着用者の臀部に対応する長手方向の一方側に少なくとも一対の折曲げ誘導部が配置されていることが好ましく、さらに、長手方向Ｌの一方側及び他方側のそれぞれに少なくとも一対ずつ配置されていることがより好ましい。 The arrangement position of at least a pair of bending guide portions is not particularly limited as long as the effect of the present invention is not impaired, but when the wearer wears the absorbent article, it is located on one side in the longitudinal direction corresponding to the wearer's buttocks. It is preferable that at least a pair of bending guide portions are arranged, and more preferably at least one pair is arranged on each of one side and the other side of the longitudinal direction L.

また、上述の軽失禁パッド１においては、二対の折曲げ誘導部５１〜５４は、図１及び図４に示すように、幅方向Ｗに延びる長手方向中心線ＣＷに対して、長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１、５２と、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３、５４と、を含んでおり、さらに長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１、５２と、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３、５４とは、長手方向中心線ＣＷを挟んで対称となるように配置されている。 Further, in the above-mentioned light incontinence pad 1, the two pairs of bending guide portions 51 to 54 are in the longitudinal direction with respect to the longitudinal center line C W extending in the width direction W as shown in FIGS. 1 and 4. It includes a pair of bending guides 51 and 52 located on one side of L and a pair of bending guides 53 and 54 located on the other side of L in the longitudinal direction, and further includes one side of L in the longitudinal direction.

本発明の吸収性物品においては、少なくとも一対の折曲げ誘導部をこのように配置することは必須の構成要件ではないものの、吸収性物品は、少なくとも一対の折曲げ誘導部が幅方向に延びる長手方向中心線に対して、長手方向の一方側に位置する一対の折曲げ誘導部と、長手方向の他方側に位置する一対の折曲げ誘導部とを含み、さらに長手方向の一方側に位置する一対の折曲げ誘導部と、長手方向の他方側に位置する一対の折曲げ誘導部とが長手方向中心線を挟んで対称となるように配置されていることが好ましい。少なくとも一対の折曲げ誘導部がこのように配置されていると、着用者の動作時に、吸収性物品の長手方向の広範囲にわたって上述の折曲げ誘導部による追従変形作用を発揮することができるという利点がある。 In the absorbent article of the present invention, it is not an essential component to arrange at least a pair of bending guide portions in this way, but in the absorbent article, at least a pair of bending guide portions extend in the width direction. It includes a pair of bending guides located on one side in the longitudinal direction and a pair of bending guides located on the other side in the longitudinal direction with respect to the center line of the direction, and is further located on one side in the longitudinal direction. It is preferable that the pair of bending guide portions and the pair of bending guide portions located on the other side in the longitudinal direction are arranged symmetrically with respect to the center line in the longitudinal direction. When at least a pair of bending guides are arranged in this way, there is an advantage that the follow-up deformation action by the above-mentioned bending guides can be exerted over a wide range in the longitudinal direction of the absorbent article during the movement of the wearer. There is.

また、上述の軽失禁パッド１においては、長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１、５２は、図１及び図４に示すように、幅方向中心線ＣＬに対して幅方向Ｗの一方側に位置する折曲げ誘導部５１の仮想延長線５１Ｌと、幅方向中心線ＣＬに対して幅方向Ｗの他方側に位置する折曲げ誘導部５２の仮想延長線５２Ｌとが同一直線上に重ならないように配置されている。
同様に、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３、５４も、幅方向中心線ＣＬに対して幅方向Ｗの一方側に位置する折曲げ誘導部５３の仮想延長線５３Ｌと、幅方向中心線ＣＬに対して幅方向Ｗの他方側に位置する折曲げ誘導部５４の仮想延長線５４Ｌとが同一直線上に重ならないように配置されている。
なお、折曲げ誘導部の仮想延長線は、平面視にて折曲げ誘導部の中心線と重なるとともにそれを延長した仮想線であり、上述の各仮想延長線５１Ｌ〜５４Ｌでは、それぞれ直線状の折曲げ誘導部５１〜５４の中心線と重なる仮想直線である。 Further, in the above-mentioned light incontinence pad 1, the pair of bending guide portions 51, 52 located on one side of the longitudinal direction L, as shown in FIGS. 1 and 4, with respect to the width direction center line CL . a virtual extension line 51L of a fold induction unit 51 located on one side in the width direction W, the virtual extension line 52L of a fold induction unit 52 located on the other side in the width direction W with respect to the width direction center line C L Are arranged so that they do not overlap on the same straight line.
Similarly, the virtual extension line of the pair of bent leading portion 53 also, the guiding section 53 bent Ori positioned on one side in the width direction W with respect to the width direction center line C L which is positioned on the other side of the longitudinal direction L and 53L, and a virtual extension line 54L of a fold induction unit 54 located on the other side in the width direction W are arranged so as not to overlap on the same straight line with respect to the width direction center line C L.
The virtual extension line of the bending guide portion is a virtual line that overlaps with and extends the center line of the bending guidance portion in a plan view, and each of the above-mentioned virtual extension lines 51L to 54L is linear. It is a virtual straight line that overlaps with the center line of the bending guide portions 51 to 54.

本発明の吸収性物品において、少なくとも一対の折曲げ誘導部をこのように配置することは必須の構成要件ではないものの、少なくとも一対の折曲げ誘導部は、幅方向中心線に対して幅方向の一方側に位置する折曲げ誘導部の仮想延長線と、幅方向中心線に対して幅方向の他方側に位置する折曲げ誘導部の仮想延長線とが同一直線上に重ならないように配置されていることが好ましい。少なくとも一対の折曲げ誘導部がこのように配置されていると、それぞれの折曲げ誘導部ごとに折れ曲がり基点を形成することができ、吸収体をより多様な形状に変形しやすくすることができる上、仮に、着用者の動作時に上述の捩じれる方向の力が折曲げ誘導部を介して吸収体の幅方向中央部分に及んだとしても、当該幅方向中央部分においては折れ曲がり基点が形成されにくく、当該吸収体の幅方向中央部分の折れ曲がりをより生じにくくすることができる。 Although it is not an essential component to arrange at least a pair of bending guides in this way in the absorbent article of the present invention, at least the pair of bending guides are in the width direction with respect to the center line in the width direction. The virtual extension line of the bending guide located on one side and the virtual extension line of the bending guide located on the other side in the width direction with respect to the center line in the width direction are arranged so as not to overlap on the same straight line. Is preferable. When at least a pair of bending guide portions are arranged in this way, a bending base point can be formed for each bending guiding portion, and the absorber can be easily deformed into a wider variety of shapes. Even if the above-mentioned twisting force is applied to the central portion of the absorber in the width direction via the bending guide portion during the movement of the wearer, it is difficult for the bending base point to be formed in the central portion in the width direction. , It is possible to make it more difficult for the central portion of the absorber to bend in the width direction.

また、上述の軽失禁パッド１においては、長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１、５２の各々は、図４に示すように、平面視にて、幅方向内方側の端部５１Ｅ、５２Ｅが一対の凹部６１、６２とそれぞれ連通している。
同様に、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３、５４の各々も、平面視にて、幅方向内方側の端部５３Ｅ、５４Ｅが一対の凹部６１、６２とそれぞれ連通している。 Further, in the above-mentioned light incontinence pad 1, each of the pair of bending guide portions 51 and 52 located on one side of the longitudinal direction L is inward in the width direction in a plan view as shown in FIG. The ends 51E and 52E of the above communicate with the pair of recesses 61 and 62, respectively.
Similarly, in each of the pair of bending guide portions 53 and 54 located on the other side in the longitudinal direction L, the end portions 53E and 54E on the inner side in the width direction are the pair of recesses 61 and 62, respectively, in a plan view. Communicating.

本発明の吸収性物品において、少なくとも一対の折曲げ誘導部をこのように配置することは必須の構成要件ではないものの、少なくとも一対の折曲げ誘導部は、各々の幅方向内方側の端部が一対の凹部と連通していることが好ましい。少なくとも一対の折曲げ誘導部がこのように配置されていると、着用者の動作時に折曲げ誘導部を介して伝わる上述の捩じれる方向の力を、一対の凹部においてより分散しやすくなり、吸収体の幅方向中央部分をより一層変形しにくくすることができる。 Although it is not an essential component to arrange at least a pair of bending guides in this way in the absorbent article of the present invention, at least a pair of bending guides are provided at the inner end in the width direction of each. Is preferably in communication with the pair of recesses. When at least a pair of bending guides are arranged in this way, the above-mentioned twisting force transmitted through the bending guides during the wearer's movement can be more easily dispersed and absorbed in the pair of recesses. The central portion in the width direction of the body can be made more difficult to deform.

なお、図４においては、折曲げ誘導部５１、５３の幅方向内方側の端部５１Ｅ、５３Ｅと長手方向Ｌに延びる凹部６１との境界及び折曲げ誘導部５２、５４の幅方向内方側の端部５２Ｅ、５４Ｅと長手方向Ｌに延びる凹部６２との境界を、それぞれ仮想線（点線）によって示している。 In FIG. 4, the boundary between the end portions 51E and 53E on the inner side in the width direction of the bending guide portions 51 and 53 and the recess 61 extending in the longitudinal direction L and the inner side in the width direction of the bending guide portions 52 and 54. The boundaries between the side ends 52E and 54E and the recess 62 extending in the longitudinal direction L are indicated by virtual lines (dotted lines), respectively.

さらに、上述の軽失禁パッド１においては、平面視にて、幅方向Ｗに延びる２本の折り線ＦＬ１、ＦＬ２を有しており、上述の二対の折曲げ誘導部５１〜５４の各々は、図１に示すように、２本の折り線ＦＬ１、ＦＬ２と交差しないように配置されている。 Further, the above-mentioned light incontinence pad 1 has two folding lines FL 1 and FL 2 extending in the width direction W in a plan view, and has two pairs of bending guiding portions 51 to 54 described above. As shown in FIG. 1, each is arranged so as not to intersect the two folding lines FL 1 and FL 2.

本発明において、吸収性物品をこのように構成することは必須の構成要件ではないものの、吸収性物品は、幅方向に延びる少なくとも２本の折り線を有し、一対の折曲げ誘導部の各々がこれらの折り線と交差しないように配置されていることが好ましい。吸収性物品がこのように構成されていると、吸収性物品をコンパクトに折り畳むことができ、収納性や携帯性などに優れたものとすることができる上、折り線による折り皺を利用した折れ曲がり基点を形成することができるので、上述の一対の折曲げ誘導部による追従変形作用を阻害せずに、吸収性物品をより多様な形状に変形しやすくすることができる。 Although it is not an essential requirement to construct the absorbent article in this way in the present invention, the absorbent article has at least two fold lines extending in the width direction and each of the pair of bend guides. Is preferably arranged so as not to intersect these fold lines. When the absorbent article is configured in this way, the absorbent article can be folded compactly, and can be excellent in storage and portability, and can be bent by using creases due to fold lines. Since the base point can be formed, the absorbent article can be easily deformed into a wider variety of shapes without impeding the follow-up deformation action of the pair of bending guides described above.

なお、本発明において、吸収性物品の折り畳み形態や各折り線の位置、折り線の本数等は、本発明の効果を阻害しない限り特に制限されない。例えば、吸収性物品は、幅方向に延びる１本の折り線を有していても、２本以上の任意の本数の折り線を有していてもよく、或いは、幅方向に延びる折り線を有していなくてもよい。 In the present invention, the folding form of the absorbent article, the position of each folding line, the number of folding lines, and the like are not particularly limited as long as the effects of the present invention are not impaired. For example, the absorbent article may have one fold line extending in the width direction, may have two or more arbitrary number of fold lines, or may have fold lines extending in the width direction. You do not have to have it.

（凹部）
そして、吸収体４は、図１に示すように平面視にて、上述の折曲げ誘導部５１〜５４の幅方向内方側に位置し且つ幅方向中心線ＣＬを挟んで対称となるように長手方向Ｌに延びるように配置され、非肌対向面側の表面から肌対向面側の表面に向かって厚さ方向Ｔに窪む、相対的に低剛性の一対の凹部６１、６２を有している。かかる一対の凹部６１、６２は、幅方向Ｗの一方側の凹部６１と他方側の凹部６２との間の距離が、吸収体４の幅方向長さの１／４以上となるように配置されており、さらに、長手方向長さが吸収体４の長手方向長さの１／１０以上となるように長手方向Ｌに延びている。 (Recess)
Then, as shown in FIG. 1, the absorber 4 is located on the inner side in the width direction of the above-mentioned bending guide portions 51 to 54 in a plan view and is symmetrical with the width direction center line CL in between. Has a pair of relatively low-rigidity recesses 61 and 62 that are arranged so as to extend in the longitudinal direction L and are recessed in the thickness direction T from the surface on the non-skin facing surface side toward the surface on the skin facing surface side. doing. The pair of recesses 61 and 62 are arranged so that the distance between the recess 61 on one side in the width direction W and the recess 62 on the other side is 1/4 or more of the length in the width direction of the absorber 4. Further, the length in the longitudinal direction extends in the longitudinal direction L so as to be 1/10 or more of the length in the longitudinal direction of the absorber 4.

なお、本発明において、折曲げ誘導部の幅方向内方側に位置する凹部の配置本数は、少なくとも一対であれば特に制限されず、長手方向に延びる凹部は、吸収体に一対だけ形成されていても、二対以上形成されていてもよい。 In the present invention, the number of recesses located on the inner side in the width direction of the bending guide portion is not particularly limited as long as it is at least one pair, and only one pair of recesses extending in the longitudinal direction is formed in the absorber. Alternatively, two or more pairs may be formed.

このように、吸収体が折曲げ誘導部の幅方向内方側の位置に長手方向に延びる少なくとも一対の凹部を有していると、着用者の動作時に、上述の折曲げ誘導部を介して吸収性物品に長手方向を軸として左右交互に捩じれる方向の力が加わったとしても、長手方向に延びる少なくとも一対の凹部によってその力を分散することができ、当該一対の凹部よりも幅方向内方側の部分、すなわち吸収体の幅方向中央部分を変形しにくくすることができる。これにより、本発明の吸収性物品は、上述の折曲げ誘導部による追従変形作用に加えて、吸収体の幅方向中央部分を的確に着用者の股間部に密着させることできるので、着用者の動作時においても優れたフィット性を発揮することができる。 As described above, when the absorber has at least a pair of recesses extending in the longitudinal direction at the position on the inner side in the width direction of the bending guide portion, the wearer operates through the above-mentioned bending guidance portion. Even if a force is applied to the absorbent article in a direction in which it is twisted alternately left and right with respect to the longitudinal direction, the force can be dispersed by at least a pair of recesses extending in the longitudinal direction, and the force can be dispersed within the width direction of the pair of recesses. The lateral portion, that is, the central portion in the width direction of the absorber can be made difficult to deform. As a result, in the absorbent article of the present invention, in addition to the follow-up deformation action by the bending guide portion described above, the central portion in the width direction of the absorber can be accurately brought into close contact with the crotch portion of the wearer. Excellent fit can be exhibited even during operation.

本発明において、長手方向に延びる凹部の形態は、折曲げ誘導部から伝わる力を長手方向に分散し得るものであれば特に制限されず、長手方向に延びる凹部は、吸水性材料の低坪量化により厚さ方向に窪んでなる低坪量部のほか、例えば、貫通又は非貫通のスリット部や吸収体をエンボス等により厚さ方向に圧搾してなる圧搾溝部などの、相対的に低剛性の凹部によって形成することができる。同様に、長手方向に延びる凹部を形成する吸収体の表面（すなわち、肌対向面側の表面及び非肌対向面側の表面）についても、上記のような折曲げ誘導部から伝わる力を長手方向に分散し得るものであれば特に限定されず、長手方向に延びる凹部は、上述の軽失禁パッド１のように吸収体の非肌対向面側の表面から肌対向面側の表面に向かって厚さ方向に窪むように形成されていても、吸収体の肌対向面側の表面から非肌対向面側の表面に向かって厚さ方向に窪むように形成されていても、あるいは吸収体の両方の表面から互いに反対側の表面に向かって厚さ方向に窪むように形成されていてもよい。 In the present invention, the form of the recess extending in the longitudinal direction is not particularly limited as long as the force transmitted from the bending guide portion can be dispersed in the longitudinal direction, and the recess extending in the longitudinal direction reduces the basis weight of the water-absorbent material. In addition to the low basis weight portion that is recessed in the thickness direction due to It can be formed by recesses. Similarly, with respect to the surface of the absorber (that is, the surface on the skin facing surface side and the surface on the non-skin facing surface side) forming the recess extending in the longitudinal direction, the force transmitted from the bending guide portion as described above is applied in the longitudinal direction. The recess extending in the longitudinal direction is not particularly limited as long as it can be dispersed in the skin, and the recess extending in the longitudinal direction is thickened from the surface of the absorber on the non-skin facing surface side to the surface on the skin facing surface side like the above-mentioned light incontinence pad 1. It may be formed to be recessed in the longitudinal direction, it may be formed to be recessed in the thickness direction from the surface of the absorber on the skin-facing surface side toward the surface on the non-skin-facing surface side, or both surfaces of the absorber. It may be formed so as to be recessed in the thickness direction toward the surfaces opposite to each other.

さらに、長手方向に延びる少なくとも一対の凹部は、平面視にて、上述の折曲げ誘導部の幅方向内方側に位置し且つ幅方向中心線を挟んで対称となるように長手方向に延びるものであれば、その延びる形態は特に制限されず、長手方向に延びる一対の凹部の各々は、例えば、直線状、点線状及び／又は曲線状に延びていても、単数又は複数の分岐を形成しながら延びていてもよい。 Further, at least a pair of recesses extending in the longitudinal direction are located inward in the width direction of the above-mentioned bending guide portion in a plan view and extend in the longitudinal direction so as to be symmetrical with respect to the center line in the width direction. If so, the extending form is not particularly limited, and each of the pair of recesses extending in the longitudinal direction forms a single or a plurality of branches even if they extend linearly, dottedly and / or curvedly, for example. However, it may be extended.

なお、長手方向に延びる少なくとも一対の凹部の配置位置等は、本発明の効果を阻害しない限り特に制限されないが、着用者が吸収性物品を着用した時に着用者の***口が当接し得る領域よりも幅方向外方側に位置し、且つ当該領域よりも長手方向に長く延びるように配置されていることが好ましい。 The arrangement position of at least a pair of recesses extending in the longitudinal direction is not particularly limited as long as the effect of the present invention is not impaired, but the area where the wearer's excretory opening can come into contact when the wearer wears the absorbent article. Is preferably located on the outer side in the width direction and is arranged so as to extend longer in the longitudinal direction than the region.

（括れ部）
また、上述の軽失禁パッド１においては、吸収体４は、図１及び図４に示すように、平面視にて長手方向中央部に、幅方向長さが相対的に小さい括れ部４１を有しており、軽失禁パッド１が着用者の股間部に密着しやすくなっている。なお、吸収体４がこのような括れ部４１を有していると、軽失禁パッド１の構成部材の中でも相対的に剛性の高い吸収体４が着用者の両脚の内側部分に接触しにくくなるため、着用者に異物感を生じさせにくくすることができる。 (Constriction)
Further, in the above-mentioned light incontinence pad 1, as shown in FIGS. 1 and 4, the absorber 4 has a constricted portion 41 having a relatively small width direction in the central portion in the longitudinal direction in a plan view. This makes it easier for the light incontinence pad 1 to come into close contact with the wearer's crotch. When the absorber 4 has such a constricted portion 41, it becomes difficult for the absorber 4, which has relatively high rigidity among the constituent members of the light incontinence pad 1, to come into contact with the inner portions of both legs of the wearer. Therefore, it is possible to make it difficult for the wearer to feel a foreign body.

さらに、上述の軽失禁パッド１においては、上記二対の折曲げ誘導部５１〜５４の各々が、この括れ部４１に配置されている。
本発明の吸収性物品において、折曲げ誘導部をこのような括れ部に配置することは必須の構成要件ではないものの、少なくとも一対の折曲げ誘導部は、このような括れ部に配置されていることが好ましい。少なくとも一対の折曲げ誘導部がこのような着用者の脚周りに対応する括れ部に配置されていると、当該折曲げ誘導部が着用者の脚の動きに応じて変形しやすく、より的確に上述の追従変形作用を発揮することができる。 Further, in the light incontinence pad 1 described above, each of the two pairs of bending guiding portions 51 to 54 is arranged in the constricted portion 41.
In the absorbent article of the present invention, although it is not an essential component to arrange the bending guide portion in such a constriction portion, at least a pair of bending guide portions are arranged in such a constriction portion. Is preferable. When at least a pair of bending guides are arranged in the constriction corresponding to the wearer's legs, the bending guides are easily deformed according to the movement of the wearer's legs, and more accurately. The above-mentioned follow-up deformation action can be exhibited.

また、上述の軽失禁パッド１においては、上記の折曲げ誘導部５１〜５４の各々は、図１に示すように、幅方向外方側の端部が括れ部４１の長手方向外方側において吸収体４の最大幅を有する最大幅部４３と、括れ部４１において吸収体４の最小幅を有する最小幅部４２との間に位置し、且つ最大幅部４３と最小幅部４２との間の長手方向中間位置よりも長手方向外方側に位置している。 Further, in the above-mentioned light incontinence pad 1, each of the above-mentioned bending guide portions 51 to 54 has an end portion on the outer side in the width direction on the outer side in the longitudinal direction of the constricted portion 41, as shown in FIG. It is located between the maximum width portion 43 having the maximum width of the absorber 4 and the minimum width portion 42 having the minimum width of the absorber 4 in the constricted portion 41, and between the maximum width portion 43 and the minimum width portion 42. It is located on the outer side in the longitudinal direction from the intermediate position in the longitudinal direction of.

本発明の吸収性物品において、折曲げ誘導部をこのように配置することは必須の構成要件ではないものの、少なくとも一対の折曲げ誘導部の各々の幅方向外方側の端部がこのような特定の部分に位置していると、着用者の脚の動きが大きいような場合でも、折曲げ誘導部がその動きに応じて的確に変形することができ、上述の効果をより安定的に且つ確実に発揮することができる。 In the absorbent article of the present invention, such arrangement of the bending guides is not an essential component, but at least the widthwise outer ends of each of the pair of bending guides are such. When it is located in a specific part, even if the wearer's leg moves a lot, the bending guide can be accurately deformed according to the movement, and the above-mentioned effect can be more stable and more stable. It can be demonstrated reliably.

なお、本発明の吸収性物品において、吸収体が上述のような括れ部を有することは必須の構成要件ではないため、吸収体は、例えば、幅方向長さが長手方向に一定となる構造を有していてもよい。 In the absorbent article of the present invention, it is not an indispensable constituent requirement that the absorber has a constricted portion as described above, so that the absorber has, for example, a structure in which the length in the width direction is constant in the longitudinal direction. You may have.

本発明において、吸収体の平面視形状や各種寸法、坪量等は、吸収性物品の吸収体として用い得るものであれば特に制限されず、所望の吸収性能や柔軟性、強度等に応じた任意の形状（例えば、長方形、楕円形、砂時計形等）や各種寸法、坪量等を採用することができる。 In the present invention, the plan-view shape, various dimensions, basis weight, etc. of the absorber are not particularly limited as long as they can be used as an absorber of an absorbent article, and can be adjusted according to desired absorption performance, flexibility, strength, and the like. Any shape (for example, rectangle, ellipse, hourglass, etc.), various dimensions, basis weight, etc. can be adopted.

また、吸収体が配置される位置についても、吸収性物品の長手方向中央部を含む位置であれば特に制限されず、吸収体は、例えば吸収性物品における長手方向の一方寄りに偏って配置されていてもよい。 Further, the position where the absorber is arranged is not particularly limited as long as it includes the central portion in the longitudinal direction of the absorbent article, and the absorber is arranged unevenly toward one side in the longitudinal direction in, for example, the absorbent article. You may be.

なお、本発明の吸収性物品においては、吸収体は、肌対向面側に位置する肌対向面側吸収層や表面シート、中間シートなどの構成部材と接着層を介して接合されていてもよい。このように、吸収体が肌対向面側に位置する構成部材と接着層を介して接合されていると、着用者の動作時においても吸収体が型崩れしにくく、より優れたフィット性を発揮することができる。 In the absorbent article of the present invention, the absorber may be bonded to a constituent member such as an absorbent layer on the skin-facing surface side, a surface sheet, or an intermediate sheet located on the skin-facing surface side via an adhesive layer. .. In this way, when the absorber is joined to the component located on the side facing the skin via the adhesive layer, the absorber does not easily lose its shape even during the wearer's movement, and exhibits better fit. can do.

また、上述の接着層は、平面視にて、長手方向と平行な仮想線と交差する部分を有しながら、長手方向に延在していることが好ましい。
ここで、図６は、吸収体４の肌対向面側に配置される接着層Ｈの配置形態を模式的に示す平面図である。図６において、吸収体４に配置される接着層Ｈは、平面視にてスパイラル状の形態で、すなわち、長手方向Ｌと平行な仮想線Ｌ１と交差する部分を有する形態で、長手方向Ｌに延在している。
このように、接着層が平面視にて長手方向Ｌと交差する部分を有しながら、長手方向に延在している（例えば、長手方向に沿ってスパイラル状、オメガ状等の形態で配置されている）と、接着層による吸収阻害が生じにくい上、上述の捩じれる方向の力が加わるような動作時においても、折曲げ誘導部による追従変形作用を阻害せず、吸収性物品を着用者の動作に的確に追従して変形させることができる。 Further, it is preferable that the above-mentioned adhesive layer extends in the longitudinal direction while having a portion intersecting with a virtual line parallel to the longitudinal direction in a plan view.
Here, FIG. 6 is a plan view schematically showing an arrangement form of the adhesive layer H arranged on the skin facing surface side of the absorber 4. 6, the adhesive layer H disposed in the absorbent body 4 is a spiral form in plan view, i.e., in a form having a longitudinal direction L parallel portion intersecting with the virtual line L 1, the longitudinal direction L It extends to.
In this way, the adhesive layer extends in the longitudinal direction while having a portion intersecting the longitudinal direction L in a plan view (for example, it is arranged in a spiral shape, an omega shape, or the like along the longitudinal direction). In addition to the fact that absorption is less likely to be hindered by the adhesive layer, the wearer wears an absorbent article without hindering the follow-up deformation action of the bending guide even during the above-mentioned operation in which a force in the twisting direction is applied. It can be deformed by accurately following the movement of.

なお、本発明において、吸収体の態様、特に吸収体に形成される少なくとも一対の折曲げ誘導部及び長手方向に延びる少なくとも一対の凹部の態様は、本発明の効果を阻害しない限り上述の軽失禁パッド１の態様に限定されない。
ここで、図７は、本発明の吸収性物品の別の実施形態に係る軽失禁パッド１’を展開した状態で表面シート２側から厚さ方向Ｔに見た平面図であり、図８は、軽失禁パッド１’の吸収体４’を展開した状態で肌対向面側から厚さ方向Ｔに見た平面図である。 In the present invention, the mode of the absorber, particularly the mode of at least a pair of bending guides formed on the absorber and at least a pair of recesses extending in the longitudinal direction, is the above-mentioned light incontinence unless the effect of the present invention is impaired. It is not limited to the aspect of the pad 1.
Here, FIG. 7 is a plan view of the light incontinence pad 1'according to another embodiment of the absorbent article of the present invention as viewed from the surface sheet 2 side in the thickness direction T, and FIG. 8 is a plan view. , It is a plan view seen in the thickness direction T from the skin facing surface side in a state where the absorber 4'of the light incontinence pad 1'is unfolded.

この別の実施形態の軽失禁パッド１’においては、厚さ方向Ｔにおいて、軽失禁パッド１’の肌対向面を形成する液透過性の表面シート２と、軽失禁パッド１の非肌対向面を形成する裏面シート（不図示）と、これらのシートの間に位置する吸収体４’とを、基本構成として備えており、さらに、裏面シートの非肌対向面側の表面に配置され、軽失禁パッド１’を着用者の着衣の内面に粘着固定する粘着部（不図示）を更に備えている。 In the light incontinence pad 1'of this other embodiment, the liquid permeable surface sheet 2 forming the skin facing surface of the light incontinence pad 1'and the non-skin facing surface of the light incontinence pad 1 in the thickness direction T. A back sheet (not shown) forming the back sheet and an absorber 4'located between these sheets are provided as a basic configuration, and further, they are arranged on the surface of the back sheet on the non-skin facing surface side and are light. An adhesive portion (not shown) for adhesively fixing the incontinence pad 1'to the inner surface of the wearer's clothing is further provided.

この軽失禁パッド１’においては、図７に示すように、幅方向中心線ＣＬを挟んで対称となるように長手方向Ｌに延びる一対の圧搾部Ｅ’１、Ｅ’２と、当該一対の圧搾部Ｅ’１、Ｅ’２の長手方向外方側にそれぞれ位置し且つ長手方向中心線ＣＷを挟んで対称となるように幅方向Ｗに幅方向中心線ＣＬを跨ぎながら略円弧状に延びる一対の圧搾部Ｅ’３、Ｅ’４と、上記一対の圧搾部Ｅ’１、Ｅ’２の長手方向外方側にそれぞれ位置し且つ長手方向中心線ＣＷを挟んで対称となるように上記一対の圧搾部Ｅ’３、Ｅ’４よりも大きな弧を描くように延びる一対の圧搾部Ｅ’５、Ｅ’６と、軽失禁パッド１の外周縁部に沿って連続的に延びるラウンドシール部と、を有している。 The light incontinence pad 1 'in, as shown in FIG. 7, the longitudinal extending direction L pair of compression portions E so as to be symmetrical with respect to the width direction center line C L' and 1, E '2, the pair the compressing portion E '1, E' 2 in the longitudinal direction outward while spanning the width direction center line C L in the width direction W so as to be symmetrical position to and across the longitudinal centerline C W respectively side substantially circular a pair of compression portions E '3, E' 4 extending in an arc, and symmetrical with respect to the above pair of compression portions E '1, E' 2 of respectively positioned longitudinally outward and longitudinal center line C W and the pair of compression portions E '3, E' pair of compression portions extending so as to draw a greater arc than 4 E '5, E' 6 so continuously along the outer edge of the light incontinence pad 1 It has a round seal portion extending to.

また、この軽失禁パッド１’においても、吸収体４’は、図７及び図８に示すように平面視にて、軽失禁パッド１’の長手方向Ｌに延びる幅方向中心線ＣＬを挟んで対称となるように配置され、非肌対向面側の表面から肌対向面側の表面に向かって厚さ方向Ｔに窪む、相対的に低剛性の二対の折曲げ誘導部５１’〜５４’と、これら二対の折曲げ誘導部５１’〜５４’の幅方向内方側に位置し且つ幅方向中心線ＣＬを挟んで対称となるように長手方向Ｌに延びるように配置され、非肌対向面側の表面から肌対向面側の表面に向かって厚さ方向Ｔに窪む、相対的に低剛性の一対の凹部６１’、６２’と、を有している。さらに、上記の折曲げ誘導部５１’〜５４’の各々は、吸収体４’の幅方向端縁４Ｗ１，４Ｗ２から幅方向内方側に向かって延び、且つ幅方向内方側に向かうにつれて、長手方向内方側に向かうように延びるとともに、吸収体４’の幅方向端縁４Ｗ１，４Ｗ２から幅方向内方側に向かう途中部分において、幅方向内方側に向かうにつれて、長手方向外方側に向かうように分岐する分岐部５１’Ｂ〜５４’Ｂを有している。折曲げ誘導部５１’〜５４’がこのような分岐部５１’Ｂ〜５４’Ｂを有していると、尿などの***液が折曲げ誘導部５１’〜５４’を伝って長手方向Ｌに拡散したとしても、***液を幅方向内方側へ誘導することができるので、***液の漏れをより生じにくくすることができる。 Also, 'even in the absorber 4' The light incontinence pad 1, in plan view as shown in FIGS. 7 and 8, across the width direction center line C L extending in the longitudinal direction L of the light incontinence pad 1 ' Two pairs of relatively low-rigidity bending guides 51'~, which are arranged symmetrically with each other and are recessed in the thickness direction T from the surface on the non-skin facing surface side toward the surface on the skin facing surface side. 'and these two pairs of the bent guiding portion 51'～54' 54 are arranged so as to extend in the longitudinal direction L such that the width direction located on the inner side and symmetrical with respect to the width direction center line C L of It has a pair of relatively low-rigidity recesses 61'and 62', which are recessed in the thickness direction T from the surface on the non-skin facing surface side toward the surface on the skin facing surface side. Further, each of the above-mentioned bending guide portions 51'to 54' extends inward in the width direction from the widthwise edge 4W 1 , 4W 2 of the absorber 4'and is inward in the width direction. As it extends inward in the longitudinal direction, it extends inward in the width direction in the middle of the absorber 4'from the width edge 4W 1 , 4W 2 toward the inward side in the width direction. It has branching portions 51'B to 54'B that branch so as to go outward in the direction. When the bending guide portions 51'to 54'have such branch portions 51'B to 54'B, excrement liquid such as urine travels along the bending guidance portions 51' to 54'and is L in the longitudinal direction. Even if it diffuses into the water, the excrement liquid can be guided inward in the width direction, so that the leakage of the excrement liquid can be made less likely to occur.

さらに、この軽失禁パッド１’においても、長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１’、５２’の各々は、図８に示すように、平面視にて、幅方向内方側の端部５１’Ｅ、５２’Ｅが一対の凹部６１’、６２’の長手方向Ｌの一方側端部とそれぞれ連通している。
同様に、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３’、５４’の各々も、平面視にて、幅方向内方側の端部５３’Ｅ、５４’Ｅが一対の凹部６１’、６２’の長手方向の他方側端部とそれぞれ連通している。 Further, also in this light incontinence pad 1', each of the pair of bending guide portions 51'and 52' located on one side of the longitudinal direction L is within the width direction in a plan view as shown in FIG. The lateral ends 51'E and 52'E communicate with one side end of the pair of recesses 61'and 62' in the longitudinal direction L, respectively.
Similarly, each of the pair of bending guide portions 53'and 54'located on the other side in the longitudinal direction L also has a pair of end portions 53'E and 54'E on the inner side in the width direction in a plan view. It communicates with the other end of the recesses 61'and 62'in the longitudinal direction, respectively.

一対の折曲げ誘導部及び長手方向に延びる一対の凹部がこのように配置されていると、上述の軽失禁パッド１と同様に、着用者の動作時に折曲げ誘導部を介して伝わる上述の捩じれる方向の力を、一対の凹部においてより分散しやすくなり、吸収体の幅方向中央部分をより一層変形しにくくすることができる。 When the pair of bending guides and the pair of recesses extending in the longitudinal direction are arranged in this way, the above-mentioned twist transmitted through the bending guides during the wearer's operation, similar to the above-mentioned light incontinence pad 1. The force in the direction of movement can be more easily dispersed in the pair of recesses, and the central portion in the width direction of the absorber can be made more difficult to be deformed.

なお、図８においても、折曲げ誘導部５１’、５３’ の幅方向内方側の端部５１’Ｅ、５３’Ｅと長手方向Ｌに延びる凹部６１’との境界及び折曲げ誘導部５２’、５４’ の幅方向内方側の端部５２’Ｅ、５４’Ｅと長手方向Ｌに延びる凹部６２’との境界を、それぞれ仮想線（点線）によって示している。 Also in FIG. 8, the boundary between the widthwise inward end portions 51'E and 53'E of the bending guide portions 51'and 53'and the recess 61'extending in the longitudinal direction L and the bending guidance portion 52. The boundaries between the inner ends 52'E and 54'E of', 54' in the width direction and the recess 62'extending in the longitudinal direction L are indicated by virtual lines (dotted lines), respectively.

また、この軽失禁パッド１’においても、長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１’、５２’と、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３’、５４’とが、長手方向中心線ＣＷを挟んで対称となるように配置されている。
さらに、この軽失禁パッド１’においても、長手方向Ｌの一方側に位置する一対の折曲げ誘導部５１’、５２’が、幅方向中心線ＣＬに対して幅方向Ｗの一方側に位置する折曲げ誘導部５１’の仮想延長線５１’Ｌと、幅方向中心線ＣＬに対して幅方向Ｗの他方側に位置する折曲げ誘導部５２’の仮想延長線５２’Ｌとが同一直線上に重ならないように配置されており、同様に、長手方向Ｌの他方側に位置する一対の折曲げ誘導部５３’、５４’も、幅方向中心線ＣＬに対して幅方向Ｗの一方側に位置する折曲げ誘導部５３’の仮想延長線５３’Ｌと、幅方向中心線ＣＬに対して幅方向Ｗの他方側に位置する折曲げ誘導部５４’の仮想延長線５４’Ｌとが同一直線上に重ならないように配置されている。 Further, also in this light incontinence pad 1', a pair of bending guide portions 51'and 52'located on one side of the longitudinal direction L and a pair of bending guiding portions 53'located on the other side of the longitudinal direction L. , 54'are arranged symmetrically with respect to the longitudinal center line C W.
Furthermore, 'even in a pair of the bent guiding portion 51 located on one side of the longitudinal direction L' The light incontinence pad 1, 52 'is positioned on one side in the width direction W with respect to the width direction center line C L 'and imaginary extension 51'L of, a fold inducing part 52 located on the other side in the width direction W with respect to the width direction center line C L' a fold inducing part 51 and the virtual extension line 52'L of the are arranged so as not to overlap in a straight line, similarly, the pair of bent guiding portion 53 located on the other side of the longitudinal direction L ', 54' also in the width direction W with respect to the width direction center line C L on the other hand 'and imaginary extension 53'L of, a fold inducing part 54 located on the other side in the width direction W with respect to the width direction center line C L' a fold inducing part 53 positioned on the side imaginary extension 54 of the ' They are arranged so that they do not overlap with L on the same straight line.

［肌対向面側吸収層］
また、図１に示す上述の軽失禁パッド１においては、図３に示すように、吸収体４よりも肌対向面側の位置に（より具体的には、表面シート２と吸収体４の間に）肌対向面側吸収層７を有している。
かかる肌対向面側吸収層７は、図１に示すように、折曲げ誘導部５１〜５４と厚さ方向Ｔに重複する部分の幅方向長さが、吸収体４における折曲げ誘導部５１〜５４を有する部分の幅方向長さよりも大きく形成されている。 [Skin facing side absorption layer]
Further, in the above-mentioned light incontinence pad 1 shown in FIG. 1, as shown in FIG. 3, at a position closer to the skin facing surface than the absorber 4 (more specifically, between the surface sheet 2 and the absorber 4). It has an absorption layer 7 on the side facing the skin.
As shown in FIG. 1, the skin-facing surface side absorbing layer 7 has a portion in the width direction that overlaps with the bending guiding portions 51 to 54 in the thickness direction T, and the bending guiding portions 51 to 51 in the absorber 4 have a length in the width direction. It is formed larger than the width direction length of the portion having 54.

本発明の吸収性物品において、肌対向面側吸収層をこのように形成することは必須の構成要件ではないものの、肌対向面側吸収層は、一対の折曲げ誘導部と厚さ方向に重複する部分の幅方向長さが、吸収体における上記一対の折曲げ誘導部を有する部分の幅方向長さよりも大きく形成されていることが好ましい。肌対向面側吸収層がこのように形成されていると、着用者から尿などの***液が供給される前において、上述の折曲げ誘導部の変形によるヨレを生じにくくすることができるので、このような肌対向面側吸収層を備えた吸収性物品は、より優れたフィット性を発揮することができる上、ヨレによる***液の漏れも生じにくくすることができる。 In the absorbent article of the present invention, although it is not an indispensable constituent requirement to form the skin-facing surface side absorbing layer in this way, the skin-facing surface side absorbing layer overlaps with the pair of bending guide portions in the thickness direction. It is preferable that the width direction length of the portion to be formed is larger than the width direction length of the portion having the pair of bending guide portions in the absorber. When the absorption layer on the side facing the skin is formed in this way, it is possible to prevent twisting due to the above-mentioned deformation of the bending guide portion before the excrement liquid such as urine is supplied from the wearer. An absorbent article provided with such an absorbent layer on the side facing the skin can exhibit a better fit and can prevent leakage of excrement liquid due to twisting.

本発明において、肌対向面側吸収層は、着用者から排出された尿などの***液を吸収し保持し得る機能を有するものであれば特に制限されず、例えば、上述の吸収体と同様の吸水性材料からなるもの、或いは、当該吸水性材料を１枚又は２枚以上の親水性不織布などの液透過性シートで包んだものなどを好適に用いることができる。 In the present invention, the absorption layer on the side facing the skin is not particularly limited as long as it has a function of absorbing and retaining excrement liquid such as urine discharged from the wearer, and is, for example, the same as the above-mentioned absorber. A material made of a water-absorbent material, or a material obtained by wrapping the water-absorbent material with one or more sheets of a liquid-permeable sheet such as a hydrophilic non-woven fabric can be preferably used.

さらに、本発明の吸収性物品においては、肌対向面側吸収層が少なくとも吸収性ポリマーを含むものであることが好ましい。肌対向面側吸収層が少なくとも吸収性ポリマーを含んでいると、着用者から尿などの***液が供給されたときに、肌対向面側吸収層が***液を吸収して膨張し、当該肌対向面側吸収層の非肌対向面側に位置する吸収体のヨレをより生じにくくすることができる。これにより、このような肌対向面側吸収層を備えた吸収性物品は、着用者の***後においても優れたフィット性を維持しやすく、ヨレに起因する***液の漏れを生じにくくすることができる。 Further, in the absorbent article of the present invention, it is preferable that the absorbent layer on the skin-facing surface side contains at least an absorbent polymer. If the skin-facing surface absorbing layer contains at least an absorbent polymer, when the wearer supplies excrement such as urine, the skin-facing surface absorbing layer absorbs the excrement and swells, causing the skin to swell. It is possible to make it more difficult for the absorbent body located on the non-skin facing surface side of the absorbing layer on the facing surface side to be twisted. As a result, the absorbent article provided with the absorption layer on the side facing the skin can easily maintain an excellent fit even after excretion by the wearer, and can prevent the excrement liquid from leaking due to twisting. it can.

なお、吸収性ポリマーは、水を吸収して保持することができるポリマーであり、例えば水溶性高分子が適度に架橋された三次元網目構造を有するポリマーなどが挙げられる。具体的には、デンプン系、アクリル酸系、アミノ酸系の粒子状又は繊維状のポリマーなどが挙げられる。 The absorbent polymer is a polymer capable of absorbing and retaining water, and examples thereof include a polymer having a three-dimensional network structure in which a water-soluble polymer is appropriately crosslinked. Specific examples thereof include starch-based, acrylic acid-based, and amino acid-based particulate or fibrous polymers.

本発明において、肌対向面側吸収層の平面視形状や各種寸法、坪量等は、本発明の効果を阻害しない限り特に制限されず、所望の吸収性能や柔軟性、強度等に応じた任意の形状（例えば、長方形、楕円形、砂時計形等）や各種寸法、坪量等を採用することができる。そもそも本発明の吸収性物品において、このような肌対向面側吸収層を備えることは必須の構成要件ではないため、吸収性物品はこのような肌対向面側吸収層を備えていなくてもよい。 In the present invention, the plan-view shape, various dimensions, basis weight, etc. of the absorption layer on the side facing the skin are not particularly limited as long as the effects of the present invention are not impaired, and are arbitrary according to desired absorption performance, flexibility, strength, and the like. (For example, rectangular shape, oval shape, hourglass shape, etc.), various dimensions, basis weight, etc. can be adopted. In the first place, in the absorbent article of the present invention, it is not an indispensable constituent requirement to include such a skin-facing surface side absorbing layer, so that the absorbent article may not be provided with such a skin-facing surface side absorbing layer. ..

［粘着部］
上述の軽失禁パッド１において、当該軽失禁パッド１を着用者の着衣の内面に粘着固定するための粘着部８は、図２に示すように、裏面シート３の非肌対向面側の表面において長手方向Ｌに連続的に延在し且つ幅方向Ｗに所定の間隔をあけて並ぶ、６本のストライプ状の形態で配置されている。 [Adhesive part]
In the above-mentioned light incontinence pad 1, the adhesive portion 8 for adhesively fixing the light incontinence pad 1 to the inner surface of the wearer's clothes is on the surface of the back surface sheet 3 on the non-skin facing surface side as shown in FIG. They are arranged in the form of six stripes that extend continuously in the longitudinal direction L and are arranged at predetermined intervals in the width direction W.

なお、このような粘着部８の表面には、通常、粘着部８を保護するための剥離シート（不図示）が貼付されているため、軽失禁パッド１を着用者の着衣の内面に粘着固定する際には、その剥離シートを剥がしてから、粘着部８を着衣の内面に押し当てることにより、軽失禁パッド１を着衣の内面に粘着固定することができる。 Since a release sheet (not shown) for protecting the adhesive portion 8 is usually attached to the surface of such an adhesive portion 8, the light incontinence pad 1 is adhesively fixed to the inner surface of the wearer's clothes. In this case, the light incontinence pad 1 can be adhesively fixed to the inner surface of the garment by peeling off the release sheet and then pressing the adhesive portion 8 against the inner surface of the garment.

そして、上述の軽失禁パッド１においては、折曲げ誘導部５１〜５４の各々は、図２に示すように、粘着部８と厚さ方向Ｔに部分的に重なるように配置されている。
本発明の吸収性物品において、上述の一対の折曲げ誘導部をこのように配置することは必須の構成要件ではないものの、上述の一対の折曲げ誘導部の各々は、裏面シートの非肌対向面側の表面に配置された粘着部と厚さ方向に重ならない又は部分的に重なるように配置されていることが好ましい。このように、一対の折曲げ誘導部の各々が粘着部と厚さ方向に完全には重ならないように配置されていると、上述の一対の折曲げ誘導部による追従変形作用を阻害せずに、吸収性物品を着用者の着衣に固定することができ、優れたフィット性をより安定的に発揮することができる。 Then, in the above-mentioned light incontinence pad 1, each of the bending guide portions 51 to 54 is arranged so as to partially overlap the adhesive portion 8 in the thickness direction T, as shown in FIG.
In the absorbent article of the present invention, although it is not an essential component to arrange the pair of bending guides in this way, each of the pair of bending guides described above is non-skin facing the back sheet. It is preferable that the adhesive portion is arranged so as not to overlap or partially overlap with the adhesive portion arranged on the surface on the surface side in the thickness direction. In this way, when each of the pair of bending guide portions is arranged so as not to completely overlap the adhesive portion in the thickness direction, the follow-up deformation action of the pair of bending guide portions described above is not hindered. , The absorbent article can be fixed to the wearer's clothes, and excellent fit can be exhibited more stably.

さらに、上述の軽失禁パッド１においては、粘着部８は、図２に示すように、平面視にて、各折曲げ誘導部５１〜５４よりも長手方向外方側の位置まで延在するように配置されている。
本発明の吸収性物品において、粘着部をこのように配置することは必須の構成要件ではないものの、粘着部は、少なくとも上記の一対の折曲げ誘導部よりも長手方向外方側の位置に配置されていることが好ましい。粘着部がこのように配置されていると、上述の折曲げ誘導部が折れ曲がり基点として機能しても、当該折曲げ誘導部の長手方向外方側の部分を着用者の着衣に着実に固定することができ、吸収性物品が着用中に捲れたり、剥がれたりするようなことを生じにくくすることができる。 Further, in the above-mentioned light incontinence pad 1, as shown in FIG. 2, the adhesive portion 8 extends to a position on the outer side in the longitudinal direction from the bending guide portions 51 to 54 in a plan view.

Although it is not an essential component to arrange the adhesive portion in this way in the absorbent article of the present invention, the adhesive portion is arranged at least at a position on the outer side in the longitudinal direction from the above-mentioned pair of bending guide portions. It is preferable that it is. When the adhesive portion is arranged in this way, even if the above-mentioned bending guide portion functions as a bending base point, the portion on the outer side in the longitudinal direction of the bending guide portion is steadily fixed to the wearer's clothes. It is possible to prevent the absorbent article from being rolled up or peeled off during wearing.

また、上述の軽失禁パッド１においては、粘着部８は、図２に示すように、平面視にて、吸収体４と厚さ方向Ｔに重複する領域内に配置され、且つ、長手方向Ｌに延びる幅方向中心線ＣＬを挟んでその両側に配置されている。粘着部８がこのように配置されていると、吸収体４と厚さ方向に重複する部分を着用者の着衣の内面の形状に沿わせて着実に粘着固定することができ、さらに、着用中に着用者の両脚や臀部が左右交互に動いたりしても、着用者の着衣と共にその動きに追従して変形しやすいため、着用中に軽失禁パッド１がめくれたり、剥がれたりするようなことが生じにくくなる。 Further, in the above-mentioned light incontinence pad 1, as shown in FIG. 2, the adhesive portion 8 is arranged in a region overlapping the absorber 4 in the thickness direction T in a plan view, and is arranged in the longitudinal direction L. They are arranged on both sides of the widthwise center line C L extending. When the adhesive portion 8 is arranged in this way, the portion overlapping with the absorber 4 in the thickness direction can be steadily adhesively fixed along the shape of the inner surface of the wearer's clothing, and further, during wearing. Even if the wearer's legs and buttocks move alternately left and right, the light incontinence pad 1 may turn over or peel off during wearing because it easily deforms along with the wearer's clothes. Is less likely to occur.

このような粘着部に用い得る粘着剤としては、当分野において公知の任意の粘着剤を採用することができ、例えば、スチレン−エチレン−ブタジエン−スチレン（ＳＥＢＳ）、スチレン−ブタジエン−スチレン（ＳＢＳ）、スチレン−イソプレン−スチレン（ＳＩＳ）等のスチレン系コポリマーを主体とした感圧型粘着剤などを用いることができる。 As the pressure-sensitive adhesive that can be used for such a pressure-sensitive adhesive portion, any pressure-sensitive adhesive known in the art can be used, for example, styrene-ethylene-butadiene-styrene (SEBS), styrene-butadiene-styrene (SBS). , Styrene-Isoprene-Styrene (SIS) and other pressure-sensitive adhesives mainly composed of styrene-based copolymers can be used.

なお、本発明の吸収性物品において、粘着部の配置量や配置形状等は、本発明の効果を阻害しない限り特に制限されず、粘着部は、裏面シートの非肌対向面側の表面において、例えば、長手方向Ｌに１本又は２本以上の複数本の直線状（ストライプ状）、点線状、曲線状、ジグザグ状等の任意の線状の形態で配置することができる。また、粘着部は、上述のように長手方向Ｌに連続的に延在していても、間欠的に延在していてもよい。 In the absorbent article of the present invention, the arrangement amount, arrangement shape, etc. of the adhesive portion are not particularly limited as long as the effect of the present invention is not impaired, and the adhesive portion is formed on the surface of the back surface sheet on the non-skin facing surface side. For example, it can be arranged in any linear form such as one or a plurality of linear lines (stripes), dotted lines, curved lines, and zigzags in the longitudinal direction L. Further, the adhesive portion may extend continuously in the longitudinal direction L as described above, or may extend intermittently.

さらに、粘着部の各種寸法（例えば、長手方向長さ、幅方向長さ等）や坪量等も、本発明の効果を阻害しない限り特に制限されず、軽失禁パッドの着衣への固定のしやすさやフィット性などを考慮した任意の寸法や坪量等を採用することができる。そもそも本発明の吸収性物品において、このような粘着部を備えることは必須の構成要件ではないため、吸収性物品はこのような粘着部を備えていなくてもよい。 Further, various dimensions (for example, length in the longitudinal direction, length in the width direction, etc.) and basis weight of the adhesive portion are not particularly limited as long as the effects of the present invention are not impaired, and the light incontinence pad can be fixed to clothing. Arbitrary dimensions, basis weight, etc. can be adopted in consideration of ease of use and fit. In the first place, in the absorbent article of the present invention, it is not an indispensable constituent requirement to have such an adhesive portion, so that the absorbent article does not have to be provided with such an adhesive portion.
