<Overall composition of napkin>
An absorbent article 1 including an absorbent core 4 of the present invention includes a main body M and a pair of wing parts W, as shown in FIG. The absorbent article 1 is configured as a sanitary napkin, and is hereinafter referred to as the napkin 1.
The napkin 1 has a vertical direction X that corresponds to the front-back direction of the wearer and a horizontal direction Y that corresponds to the left-right direction of the wearer and is orthogonal to the vertical direction X. Furthermore, the napkin 1 has a thickness direction Z that is orthogonal to both the longitudinal direction X and the lateral direction Y. In this specification, with respect to the thickness direction Z, the side closer to the wearer's skin when worn is sometimes referred to as the upper or skin side, and the side closer to clothing is sometimes referred to as the lower or non-skin side. "When worn" here means a state in which the normal proper wearing position, that is, the correct wearing position of the absorbent article is maintained. Moreover, in this specification, "planar view" means a planar view seen from the thickness direction Z.

本体Ｍは、縦方向Ｘに沿って延び、着用時に着用者の着衣の内面にナプキン１の非肌側面１ｂに配された粘着部（図示せず）によって固定される。本体Ｍは、後述する吸収体４を有しており、着用者の経血等の液状物（以下、「液」とも称する）を吸収する機能を有する。
本体Ｍは、縦方向Ｘに沿って、前方部Ｍ１と、中央部Ｍ２と、後方部Ｍ３と、に区分される。
中央部Ｍ２は、着用時に着用者の排泄部に対向する排泄部対向領域である。図１において、中央部Ｍ２は、本体Ｍにおけるウイング部Ｗの前後基端部間の領域である。
前方部Ｍ１は、中央部Ｍ２の前方（着用者の腹側）に配置される領域であり、着用時に着用者の排泄部の前方に対向するように構成される。
後方部Ｍ３は、中央部Ｍ２の後方（着用者の背側）に配置される領域であり、装着時に着用者の排泄部の後方に対向するように構成される。 The main body M extends along the longitudinal direction X, and is fixed to the inner surface of the wearer's clothes when worn by an adhesive part (not shown) arranged on the non-skin side surface 1b of the napkin 1. The main body M has an absorbent body 4, which will be described later, and has a function of absorbing liquid substances (hereinafter also referred to as "liquid") such as menstrual blood of the wearer.
The main body M is divided along the longitudinal direction X into a front part M1, a central part M2, and a rear part M3.
The central portion M2 is an excretory part facing area that faces the wearer's excretory part when worn. In FIG. 1, a central portion M2 is a region between the front and rear base end portions of the wing portions W in the main body M.
The front part M1 is a region arranged in front of the central part M2 (on the ventral side of the wearer), and is configured to face the front of the wearer's excretory part when worn.
The rear part M3 is a region located behind the central part M2 (on the back side of the wearer), and is configured to face the rear of the wearer's excretory part when worn.

ウイング部Ｗは、本体Ｍの中央部Ｍ２から横方向Ｙ外側に突出する。ウイング部Ｗは、着用時に着用者の着衣の外面にナプキン１の非肌側面１ｂに配された粘着部（図示せず）によって固定される。 The wing portion W protrudes outward in the lateral direction Y from the central portion M2 of the main body M. The wing portion W is fixed to the outer surface of the wearer's clothing by an adhesive portion (not shown) disposed on the non-skin side surface 1b of the napkin 1 when worn.

図２及び３に示すように、ナプキン１は、吸収体４と、表面シート２と、裏面シート３と、一対のサイドシート５と、を備える。本体Ｍにおいて、ナプキン１は、裏面シート３、吸収体４及び表面シート２が厚み方向Ｚに積層された構成を有する。これらの構成は、例えば、接着剤やヒートシール等による接合、及び後述する圧搾部によるエンボス加工等によって、適宜接合されて一体化している。 As shown in FIGS. 2 and 3, the napkin 1 includes an absorbent core 4, a top sheet 2, a back sheet 3, and a pair of side sheets 5. In the main body M, the napkin 1 has a structure in which a back sheet 3, an absorbent core 4, and a top sheet 2 are laminated in the thickness direction Z. These structures are appropriately joined and integrated, for example, by joining with an adhesive, heat sealing, etc., and by embossing with a compressed part, which will be described later.

図１～３に示すように、吸収体４は、縦方向Ｘに沿って延び、表面シート２と裏面シート３との間に配置される。吸収体４は、排泄された液を表面シート２側の面から吸収し、内部で拡散させて当該液を保持する。
吸収体４は、吸収性コア４１と、コアラップシート４２と、を有する。
吸収性コア４１は、吸収性材料で構成される。例えば、吸収性材料は、パルプ繊維等の親水性繊維で構成された繊維集合体でもよいし、当該繊維集合体に吸水性ポリマーを保持させたものでもよい。
コアラップシート４２は、吸収性コア４１を被覆し、例えば吸収性コア４１の形状を保持する機能等を有する。コアラップシート４２は、例えばティッシュペーパー状の薄く柔らかい紙や液透過性の不織布等で形成される。
吸収体４の詳細な構成については後述する。 As shown in FIGS. 1 to 3, the absorbent body 4 extends along the longitudinal direction X and is disposed between the topsheet 2 and the backsheet 3. The absorber 4 absorbs the excreted liquid from the surface on the top sheet 2 side, diffuses it inside, and retains the liquid.
The absorbent body 4 has an absorbent core 41 and a core wrap sheet 42.
Absorbent core 41 is made of absorbent material. For example, the absorbent material may be a fiber aggregate made of hydrophilic fibers such as pulp fibers, or may be one in which a water-absorbing polymer is held in the fiber aggregate.
The core wrap sheet 42 has a function of covering the absorbent core 41 and, for example, maintaining the shape of the absorbent core 41. The core wrap sheet 42 is made of, for example, thin, soft paper such as tissue paper, liquid-permeable nonwoven fabric, or the like.
The detailed structure of the absorber 4 will be described later.

表面シート２は、液透過性を有する。表面シート２は、吸収体４の肌側面４ａに位置し、吸収体４の厚み方向Ｚ上方に配置される。表面シート２を形成するシート材は、吸収性物品の表面シートとして適用可能なものであれば特に限定されない。なお、表面シート２と吸収体４との間には、表面シート２から吸収体４への液の透過性の向上、吸収体４に吸収された液の表面シート２への液戻りの防止等の観点から、セカンドシートが配置されていてもよい。 The top sheet 2 has liquid permeability. The top sheet 2 is located on the skin side 4a of the absorbent core 4 and is arranged above the absorbent core 4 in the thickness direction Z. The sheet material forming the topsheet 2 is not particularly limited as long as it is applicable as a topsheet of an absorbent article. In addition, between the top sheet 2 and the absorbent body 4, there is a material that improves the permeability of liquid from the top sheet 2 to the absorbent body 4, prevents the liquid absorbed by the absorbent body 4 from returning to the top sheet 2, etc. From this point of view, a second seat may be provided.

裏面シート３は、吸収体４の非肌側面４ｂに位置し、吸収体４の厚み方向Ｚ下方に配置される。裏面シート３は、例えばその周縁において、表面シート２及びサイドシート５と、吸収体４を介さずに熱シール等によって接合される。裏面シート３は、接着剤等によって吸収体４に接合されていてもよい。
裏面シート３は、例えば、液難透過性、水蒸気透過性及び撥水性等の機能を有するシート材で形成される。当該シート材としては、例えば熱可塑性樹脂のフィルムや、当該フィルムと不織布とのラミネート等を用いることができる。 The back sheet 3 is located on the non-skin side surface 4b of the absorbent core 4, and is disposed below the absorbent core 4 in the thickness direction Z. The back sheet 3 is joined to the top sheet 2 and the side sheets 5 by heat sealing or the like without using the absorbent body 4, for example, at its periphery. The back sheet 3 may be bonded to the absorbent body 4 with an adhesive or the like.
The back sheet 3 is formed of a sheet material having functions such as low liquid permeability, water vapor permeability, and water repellency, for example. As the sheet material, for example, a thermoplastic resin film, a laminate of the film and a nonwoven fabric, or the like can be used.

裏面シート３の非肌側面には、例えば、ナプキン１を着衣に対して固定させる粘着部（図示せず）が設けられている。
粘着部は、例えば、裏面シート３に所定のパターンで粘着剤を塗工することにより形成される。粘着部に用いられる粘着剤として、好ましくは、ゴム系、オレフィン系、エチレン酢酸ビニル（ＥＶＡ）系等のホットメルト粘着剤が用いられる。
本実施形態において、粘着部は、本体Ｍと、ウイング部Ｗとにそれぞれ設けられる。 For example, an adhesive portion (not shown) for fixing the napkin 1 to clothing is provided on the non-skin side of the back sheet 3.
The adhesive portion is formed, for example, by applying an adhesive to the back sheet 3 in a predetermined pattern. As the adhesive used in the adhesive part, hot melt adhesives such as rubber-based, olefin-based, ethylene vinyl acetate (EVA)-based, etc. are preferably used.
In this embodiment, the adhesive portions are provided on the main body M and the wing portion W, respectively.

一対のサイドシート５は、表面シート２の横方向Ｙ外側に配置される。サイドシート５は、表面シート２よりも親水性の小さいシート材料が好ましく、例えば不織布で形成される。 The pair of side sheets 5 are arranged on the outer side of the top sheet 2 in the lateral direction Y. The side sheet 5 is preferably made of a sheet material that is less hydrophilic than the top sheet 2, and is made of, for example, nonwoven fabric.

［吸収体の外形形状］
図４を用いて吸収体４の外形形状について説明する。吸収性コア４１は平面視で吸収体４の外形形状とほぼ同じ形状であり、以下の吸収体４の外形形状の説明は、吸収性コア４１の外形形状に関する説明ともいえる。 <Structure of absorber>
[External shape of absorber]
The outer shape of the absorber 4 will be explained using FIG. 4. The absorbent core 41 has substantially the same external shape as the absorbent core 4 in plan view, and the following description of the external shape of the absorbent core 4 can also be said to be a description regarding the external shape of the absorbent core 41.

図４に示すように、吸収体４は、吸収体前方領域Ｆと、吸収体中央領域Ｃと、吸収体後方領域Ｒと、を有する。
吸収体前方領域Ｆ、吸収体中央領域Ｃ及び吸収体後方領域Ｒは、縦方向Ｘに沿って並んでいる。吸収体中央領域Ｃは、吸収体前方領域Ｆと吸収体後方領域Ｒの間に位置する。吸収体４は、吸収体４を幅方向（横方向Ｙ）に二等分する横方向Ｙ中央に位置する縦中心線ＣＬに関して左右対称な平面形状を有する。

The absorbent body front region F, the absorbent body central region C, and the absorbent body rear region R are lined up along the longitudinal direction X. The absorber central region C is located between the absorber front region F and the absorber rear region R. The absorbent body 4 has a planar shape that is bilaterally symmetrical with respect to a vertical center line CL located at the center in the horizontal direction Y that bisects the absorbent body 4 in the width direction (horizontal direction Y).
The absorbent front region F, the absorbent central region C, and the absorbent rear region R are regions located in the front portion M1, the central portion M2, and the rear portion M3 of the napkin 1, respectively. The absorber front region F and the absorber rear region R face the front and rear of the wearer's excretory region, respectively, when worn. The absorbent body central region C faces the wearer's excretory area.

図４に示すように、吸収体４は、縦方向Ｘに沿う左側縁４７ａ及び右側縁４７ｂを有する。 As shown in FIG. 4, the absorber 4 has a left side edge 47a and a right side edge 47b along the longitudinal direction X.

平面視において、吸収体４は、左右両側縁４７ａ、４７ｂに、左右一対の後方切り欠き５１と、左右一対の前方切り欠き５２を有する。吸収体４は、計４つの切り欠きを有する。一対の後方切り欠き５１及び一対の前方切り欠き５２は、それぞれ、吸収体４の横方向Ｙにおける左右両側縁４７ａ、４７ｂそれぞれから横方向Ｙ内側に向かって延びる形状に形成される。「切り欠きが横方向Ｙにおける左右両側縁４７ａ、４７ｂから横方向Ｙ内側に向かって形成される」とは、切り欠きが全体として横方向Ｙ内側に向かって延びていることを意味し、横方向Ｙと平行に延びている態様に限定されない。 In plan view, the absorber 4 has a pair of left and right rear notches 51 and a pair of left and right front notches 52 on both left and right edges 47a and 47b. The absorbent body 4 has a total of four notches. The pair of rear notches 51 and the pair of front notches 52 are each formed in a shape extending inward in the lateral direction Y from the left and right side edges 47a, 47b of the absorbent body 4 in the lateral direction Y, respectively. "The notch is formed from the left and right edges 47a, 47b inward in the lateral direction Y" means that the notch as a whole extends inward in the lateral direction Y; It is not limited to the aspect extending parallel to the direction Y.

図４において、平面視で、後方切り欠き５１により形成される後方切り欠き領域に符号５１Ｓを付し、前方切り欠き５２により形成される前方切り欠き領域に符号５２Ｓを付す。
本実施形態の吸収体４では、一対の後方切り欠き領域５１Ｓ及び一対の前方切り欠き領域５２Ｓは略半円状を有しているが、形状はこれに限定されず、例えば、略多角形状であってもよい。 In FIG. 4, in a plan view, the rear notch region formed by the rear notch 51 is designated by the reference numeral 51S, and the front notch region formed by the front notch 52 is designated by the reference numeral 52S.
In the absorber 4 of this embodiment, the pair of rear notch regions 51S and the pair of front notch regions 52S have a substantially semicircular shape, but the shape is not limited to this, and for example, they may have a substantially polygonal shape. There may be.

本明細書において、吸収体４に設けられる「切り欠き」とは、該切り欠きによって吸収体４に形成される切り欠き領域が、側縁４７ａ、４７ｂにおいて、吸収性コア４１を構成する吸収性材料が全く存在しない、つまり吸収性材料の坪量がゼロの領域を意味する。「吸収性材料が存在しない」とは、吸収性コアの本体は存在しないが、吸収性コア４１の周縁から外方へ突出した繊維や、吸収性コア４１から分離した吸収性材料の一部が若干存在している態様を含む。 In this specification, the term "notch" provided in the absorbent core 4 refers to a cutout region formed in the absorbent core 4 by the notch, which is formed on the side edges 47a, 47b of the absorbent core 41. This refers to an area where no material is present, ie, where the basis weight of the absorbent material is zero. "No absorbent material exists" means that the main body of the absorbent core is not present, but fibers protruding outward from the periphery of the absorbent core 41 or a part of the absorbent material separated from the absorbent core 41 are present. Including some existing aspects.

吸収体４において、左右一対の後方切り欠き５１により挟まれた領域を第１の領域８１といい、左右一対の前方切り欠き５２により挟まれた領域を第２の領域８２という。第１の領域８１及び第２の領域８２は、縦方向Ｘに幅を持った、横方向Ｙに延びる線状を有する。図４において、第１の領域８１及び第２の領域８２をドットで示している。 In the absorbent core 4, the area sandwiched between the left and right pair of rear notches 51 is referred to as a first area 81, and the area sandwiched between the left and right pair of front notches 52 is referred to as a second area 82. The first region 81 and the second region 82 have a linear shape that has a width in the vertical direction X and extends in the horizontal direction Y. In FIG. 4, the first region 81 and the second region 82 are indicated by dots.

平面視で、一対の後方切り欠き５１と一対の前方切り欠き５２とは縦方向Ｘに間欠配置される。
一対の後方切り欠き５１は、吸収体４における吸収体中央領域Ｃと吸収体後方領域Ｒの境界近傍、ナプキン１における中央部Ｍ２と後方部Ｍ３の境界近傍に設けられる。本実施形態の吸収体４では、一対の後方切り欠き５１は、吸収体４における吸収体後方領域Ｒに設けられ、ナプキン１における後方部Ｍ３に位置する。
一対の前方切り欠き５２は、吸収体４における吸収体前方領域Ｆと吸収体中央領域Ｃの境界近傍、ナプキン１における前方部Ｍ１と中央部Ｍ２との境界近傍に設けられる。本実施形態の吸収体４では、一対の前方切り欠き５２は、吸収体４における吸収体前方領域Ｆに設けられ、ナプキン１における前方部Ｍ１に位置する。
ナプキン１において、後方切り欠き５１は縦方向Ｘにおける後方に位置し、前方切り欠き５２は前方に位置する。 In plan view, the pair of rear notches 51 and the pair of front notches 52 are arranged intermittently in the longitudinal direction X.
The pair of rear notches 51 are provided near the boundary between the absorber central region C and the absorbent rear region R in the absorbent body 4 and near the boundary between the central portion M2 and the rear portion M3 in the napkin 1. In the absorbent body 4 of this embodiment, the pair of rear notches 51 are provided in the absorbent body rear region R of the absorbent body 4 and are located in the rear part M3 of the napkin 1.
The pair of front notches 52 are provided near the boundary between the absorber front region F and the absorbent center region C in the absorber 4 and near the border between the front portion M1 and the center portion M2 in the napkin 1. In the absorbent body 4 of this embodiment, the pair of front notches 52 are provided in the absorbent body front region F of the absorbent body 4 and are located in the front part M1 of the napkin 1.
In the napkin 1, the rear notch 51 is located at the rear in the longitudinal direction X, and the front notch 52 is located at the front.

本明細書において、「境界近傍」とは、境界自身と、境界から縦方向Ｘに２０ｍｍ以内の領域を含む。該領域内に第１の領域８１（第２の領域８２）が位置するように、左右一対の後方切り欠き５１（前方切り欠き５２）は設けられる。これにより、第１の領域８１と第２の領域８２の間にほぼ排泄部対向領域が位置する構成となる。 In this specification, "near the boundary" includes the boundary itself and a region within 20 mm from the boundary in the vertical direction X. A pair of left and right rear notches 51 (front notches 52) are provided so that the first region 81 (second region 82) is located within the region. This results in a configuration in which the excretion part facing region is located approximately between the first region 81 and the second region 82.

後方切り欠き５１及び前方切り欠き５２は、それぞれ、吸収体４を縦方向Ｘに沿って吸収体前方領域Ｆから吸収体後方領域Ｒに向けて幅（横方向Ｙにおける寸法）をみたとき、該幅が減少した後増加する部位である。左側縁４７ａにおける後方切り欠き５１と、右側縁４７ｂにおける後方切り欠き５１とは、吸収体４を縦方向Ｘに沿ってみたとき、同じ位置に位置している。前方切り欠き５２に関しても同様である。 The rear notch 51 and the front notch 52 each have a width (dimension in the horizontal direction Y) when the absorbent body 4 is viewed along the longitudinal direction X from the absorbent body front region F to the absorbent body rear region R. This is the area where the width decreases and then increases. The rear notch 51 on the left side edge 47a and the rear notch 51 on the right side edge 47b are located at the same position when the absorber 4 is viewed along the longitudinal direction X. The same applies to the front notch 52.

本実施形態の吸収体４では、第１の領域８１及び第２の領域８２を除く領域の幅（横方向Ｙにおける寸法）は、縦方向Ｘに沿ってほぼ一定に構成される。吸収体４において、第１の領域８１及び第２の領域８２は、他の領域と比較して幅が狭い領域となっている。 In the absorbent core 4 of this embodiment, the widths (dimensions in the horizontal direction Y) of the regions excluding the first region 81 and the second region 82 are configured to be substantially constant along the vertical direction X. In the absorbent body 4, the first region 81 and the second region 82 are narrower than other regions.

後方切り欠き５１及び前方切り欠き５２は、ナプキン１の着用時、着用者の動き等に伴って吸収体４に力が加わった際、吸収体４の縦方向Ｘに伝播されるよれあるいは応力に緩衝してその影響力を低下させる機能を有する。これにより、吸収体前方領域Ｆ、吸収体中央領域Ｃ、吸収体後方領域Ｒでよれが生じても、そのよれが吸収体４の全体に波及しがたく、吸収体４におけるよれ、ひいてはナプキン１におけるよれが効果的に防止される。 The rear notch 51 and the front notch 52 are designed to prevent twisting or stress propagated in the longitudinal direction It has the function of buffering and reducing its influence. As a result, even if twisting occurs in the absorber front region F, the absorber center region C, and the absorber rear region R, the twisting is difficult to spread to the entire absorbent core 4, and the napkin 1 is prevented from twisting. This effectively prevents twisting.

吸収体４において、後方切り欠き領域５１Ｓ及び前方切り欠き領域５２Ｓには、コアラップシート４２が存在していてもよいし、存在していなくてもよい。吸収体前方領域Ｆ、吸収体中央領域Ｃ、吸収体後方領域Ｒそれぞれでのよれが吸収体４全体へより波及しにくくする観点から、後方切り欠き領域５１Ｓ及び前方切り欠き領域５２Ｓにコアラップシート４２が存在していないことがより好ましい。

The compressed parts 60 and 70 are formed by compressing the main body M from the top sheet 2 side in the thickness direction Z, and have a configuration in which the top sheet 2 and the absorbent body 4 are integrally recessed toward the back sheet 3 side. . The compressed portions 60 and 70 can be formed according to a conventional method by compressing with or without heat or embossing such as ultrasonic embossing. In the pressing parts 60 and 70, the top sheet 2 and the absorbent core 4 are integrated by heat fusion or the like. As shown in FIG. 1, the compressed parts 60 and 70 have a linear shape in which a plurality of recessed parts 90 each having a substantially square planar shape are arranged intermittently in rows and can be regarded as a continuous line as a whole. There is.

吸収体４において、前方圧搾部７及び後方圧搾部６は、コアラップシート４２と吸収性コア４１が非肌側面に向かって一体的に凹陥した構成を有する。ナプキン１における後方圧搾部６０及び前方圧搾部７０それぞれと、吸収体４における後方圧搾部６及び前方圧搾部７それぞれは、平面視でほぼ同一の形状を有している。
後方圧搾部６は、吸収体４における吸収体後方領域Ｒ、ナプキン１における後方部Ｍ３に位置する。前方圧搾部７は、吸収体４における吸収体前方領域Ｆ、ナプキン１における前方部Ｍ１に位置する。 As a result, as shown in FIG. 4, in the absorbent body 4, the rear compressed part 6 that constitutes a part of the rear compressed part 60 and the front compressed part that constitutes a part of the front compressed part 70 are also provided on the skin side surface 4a. 7 is formed.

The rear compressed portion 6 is located in the absorber rear region R of the absorbent core 4 and the rear portion M3 of the napkin 1. The front compression part 7 is located in the absorber front region F of the absorbent core 4 and the front part M1 of the napkin 1.

後方圧搾部６及び前方圧搾部７は圧搾加工により形成され、他の圧搾されていない領域と比較して剛性が高い。このため、後方圧搾部６及び前方圧搾部７は、吸収体４が外力を受けた場合に、周囲の低剛性の領域の変形を促す変形起点や、該外力に対する抗力を発揮する部分として機能し得る。
また、後方圧搾部６及び前方圧搾部７は、周囲の領域と比較して繊維の密度が高くなるため、毛管作用によって排泄された液を吸液及び保持することができる。これにより、後方圧搾部６及び前方圧搾部７は、吸収体４の外方への液の漏れを防止する防漏作用も有する。 The rear compressed portion 6 and the front compressed portion 7 are formed by compression processing, and have higher rigidity than other unpressed regions. Therefore, when the absorbent core 4 receives an external force, the rear compressed portion 6 and the front compressed portion 7 function as a deformation origin that promotes deformation of the surrounding low-rigidity region, and as a portion that exerts a resistance against the external force. obtain.
In addition, the rear compressed portion 6 and the front compressed portion 7 have higher fiber density than the surrounding areas, so that they can absorb and retain the liquid excreted by capillary action.

圧搾部における「線状」は、形状が平面視において直線状の態様に限られず、曲線状の態様や、直線状部分と曲線状部分とからなる態様を含む。また、「縦方向Ｘに延びる」とは、縦方向Ｘに完全に平行な態様に限られず、前方から後方に向かって延びていればよい。
上述したように、後方圧搾部６及び前方圧搾部７は、平面形状が略四角形の複数の凹陥部９が間欠的に配されて列をなし全体的に連続した線として見做せる線状となっている。
圧搾部における「連続」した線状とは、連続した線状の凹陥部によって圧搾部が形成される態様と、本実施形態のように不連続な複数の各凹陥部が近接して配置されて列をなした集合体によって圧搾部が形成され、全体的に連続した線と見做せる態様と、を含む。圧搾部は、１つの連続した線状の凹陥部によって構成されていてもよい。不連続な複数の凹陥部の集合体によって圧搾部が形成される場合、該凹陥部の平面形状は、例えば、本実施形態で示す四角形状の他、円形状、楕円形状、多角形状、その他の形状から選ばれる１種又は２種以上を選択することができる。
また、圧搾部において、「各凹陥部が近接して配置される」とは、具体的には、隣接する凹陥部の最も近接した部分間の距離が３ｍｍ未満となるように配置されることをいう。 The pair of rear compressing parts 6 and the pair of front compressing parts 7 each extend linearly in the longitudinal direction X.
The "linear shape" in the compressed portion is not limited to a linear shape in plan view, but includes a curved shape and a shape consisting of a straight portion and a curved portion. Furthermore, "extending in the longitudinal direction X" is not limited to being completely parallel to the longitudinal direction X, but may just extend from the front to the rear.
As described above, the rear compressing part 6 and the front compressing part 7 have a linear shape in which a plurality of recesses 9 having a substantially square planar shape are arranged intermittently in rows and can be regarded as a continuous line as a whole. It has become.

The compressed portion is formed by a row of aggregates and can be regarded as a continuous line as a whole. The compressed portion may be constituted by one continuous linear recessed portion. When the compressed portion is formed by an aggregate of a plurality of discontinuous recesses, the planar shape of the recess may be, for example, not only the rectangular shape shown in this embodiment, but also a circular shape, an elliptical shape, a polygonal shape, and other shapes. One type or two or more types selected from shapes can be selected.
In addition, in the compression section, "the recesses are arranged close to each other" specifically means that the adjacent recesses are arranged so that the distance between the closest parts is less than 3 mm. say.

（後方圧搾部）
吸収体４において、左側後方圧搾部６ａと右側後方圧搾部６ｂとは、離間していても離間していなくてもよいが、ナプキンの剛性を下げ変形しやすくするためには、離間している方が好ましい。図４では、吸収体４において、左側後方圧搾部６ａと右側後方圧搾部６ｂとは離間しており、互いが連結していると見做せる線状には形成されていない。圧搾部において、「離間している」とは、左側後方圧搾部６ａと右側後方圧搾部６ｂの最も近接した部分間の距離が３ｍｍ以上となるように配置されることをいう。後述する前方圧搾部７においても同様である。 (rear compression part)
In the absorbent body 4, the left rear compressed part 6a and the right rear compressed part 6b may or may not be separated, but in order to reduce the rigidity of the napkin and make it easier to deform, it is preferable that they are separated. is preferable. In FIG. 4, in the absorber 4, the left rear compressed part 6a and the right rear compressed part 6b are separated from each other and are not formed in a linear shape that can be considered to be connected to each other. In the pressing section, "separated" means that the left rear pressing section 6a and the right rear pressing section 6b are arranged such that the distance between the closest parts is 3 mm or more. The same applies to the front pressing section 7 described later.

左側後方圧搾部６ａと右側後方圧搾部６ｂとは、縦中心線ＣＬ（横方向Ｙ中央）に関して左右対称に構成される。
図４において、左側後方圧搾部６ａは、吸収体４の縦中心線ＣＬよりも左側の領域４Ｌに位置し、右側後方圧搾部６ｂは、縦中心線ＣＬよりも右側の領域４Ｒに位置する。
左側後方圧搾部６ａは、後方に向かうにしたがって縦中心線ＣＬに向かうように延びている。右側後方圧搾部６ｂは、後方に向かうにしたがって縦中心線ＣＬに向かうように延びている。左側後方圧搾部６ａ及び右側後方圧搾部６ｂは、いずれも、縦中心線ＣＬを超えて反対側の領域まで延びて位置していない。 The left rear compression section 6a and the right rear compression section 6b are configured symmetrically with respect to the vertical center line CL (the center in the horizontal direction Y).
In FIG. 4, the left rear compressed part 6a is located in a region 4L on the left side of the longitudinal center line CL of the absorbent core 4, and the right rear compressed part 6b is located in a region 4R on the right side of the longitudinal center line CL.
The left rear compressed portion 6a extends toward the longitudinal center line CL toward the rear. The right rear pressing portion 6b extends toward the longitudinal center line CL toward the rear. Neither the left rear compressed portion 6a nor the right rear compressed portion 6b are located extending beyond the vertical center line CL to the opposite region.

左側後方圧搾部６ａ及び右側後方圧搾部６ｂは、それぞれ、後方にいくにしたがって曲率が徐々に大きくなる、全体的に緩やかに湾曲した形状を有している。
図４において、左側後方圧搾部６ａの後端部６１ａから左側後方圧搾部６ａの形状に倣って後方に仮想的に延長した仮想線６３ａ、及び、右側後方圧搾部６ｂの後端部６１ｂから右側後方圧搾部６ｂの形状に倣って後方に仮想的に延長した仮想線６３ｂを、破線で示す。左側の領域４Ｌに位置する左側後方圧搾部６ａの仮想線６３ａは、縦中心線ＣＬを超えて後方に向かって延びる。右側の領域４Ｒに位置する右側後方圧搾部６ｂの仮想線６３ｂは、縦中心線ＣＬを超えて後方に向かって延びる。

In FIG. 4, an imaginary line 63a virtually extends rearward from the rear end 61a of the left rear compressed part 6a following the shape of the left rear compressed part 6a, and a right side from the rear end 61b of the right rear compressed part 6b. An imaginary line 63b that virtually extends rearward following the shape of the rear compressed portion 6b is shown by a broken line. An imaginary line 63a of the left rear compressed portion 6a located in the left region 4L extends rearward beyond the vertical center line CL. An imaginary line 63b of the right rear compressed portion 6b located in the right region 4R extends rearward beyond the vertical center line CL.
In other words, the tangent at the rear end 61a of the left rear compressed part 6a is a right-down line that is not parallel to the lateral direction Y, and extends rearward beyond the vertical center line CL. The tangent at the rear end 61b of the right rear compressed part 6b is a left-down line that is not parallel to the horizontal direction Y, and extends rearward beyond the vertical center line CL.

一対の後方圧搾部６は、左側後方圧搾部６ａと右側後方圧搾部６ｂとの横方向Ｙにおける距離が後方にむかうに従って狭まっていく形状となっている。このような形状とすることにより、体液が縦方向Ｘに拡散し、後方圧搾部６まで到達した場合でも、後方圧搾部６によって体液をせき止め、かつ、縦方向Ｘに拡散させつつ、横方向Ｙ内方に戻すことができ、体液を吸収体４の横方向中央部に集約させやすくなっており、横洩れ及び後方への液漏れを効果的に抑制することができる。 The pair of rear compression parts 6 have a shape in which the distance in the lateral direction Y between the left rear compression part 6a and the right rear compression part 6b narrows toward the rear. By adopting such a shape, even if the body fluid diffuses in the vertical direction The body fluid can be returned inward, making it easy to collect body fluids in the lateral center of the absorber 4, and effectively suppressing side leakage and rearward fluid leakage.

図４に示す例では、左側後方圧搾部６ａ及び右側後方圧搾部６ｂは、それぞれ湾曲した形状を有するが、直線状であってもよい。この場合、直線状の左右一対の後方圧搾部間の横方向Ｙにおける距離が後方に向かうに従って小さくなるように後方圧搾部が形成される。 In the example shown in FIG. 4, the left rear compressed part 6a and the right rear compressed part 6b each have a curved shape, but they may have a straight shape. In this case, the rear compressed portions are formed such that the distance in the lateral direction Y between the pair of linear left and right rear compressed portions becomes smaller toward the rear.

（前方圧搾部）
吸収体４において、左側前方圧搾部７ａと右側前方圧搾部７ｂとは、離間していても離間していなくてもよいが、ナプキンの剛性を下げ変形しやすくするためには、離間している方が好ましい。図４では、吸収体４において、左側前方圧搾部７ａと右側前方圧搾部７ｂとは離間しており、互いが連結していると見做せる線状には形成されていない。
左側前方圧搾部７ａと右側前方圧搾部７ｂとは、縦中心線ＣＬに関して線対称に構成される。
左側前方圧搾部７ａは、吸収体４の縦中心線ＣＬよりも左側の領域４Ｌに位置し、右側前方圧搾部７ｂは、吸収体４の縦中心線ＣＬよりも右側の領域４Ｒに位置する。
左側前方圧搾部７ａは、前方に向かうにしたがって縦中心線ＣＬに向かうように延びている。右側前方圧搾部７ｂは、前方に向かうにしたがって縦中心線ＣＬに向かうように延びている。左側前方圧搾部７ａ及び右側前方圧搾部７ｂは、いずれも、縦中心線ＣＬを超えて反対側の領域まで延びて位置していない。 (front compression part)

In FIG. 4, in the absorber 4, the left front compressed portion 7a and the right front compressed portion 7b are separated from each other and are not formed in a linear shape that can be considered to be connected to each other.
The left front compressing part 7a and the right front compressing part 7b are configured symmetrically with respect to the vertical center line CL.
The left front compressed part 7a is located in a region 4L to the left of the longitudinal center line CL of the absorbent core 4, and the right front compressed part 7b is located in a region 4R to the right of the vertical center line CL of the absorbent core 4.
The left front compressed portion 7a extends toward the vertical center line CL as it goes forward. The right front compressed portion 7b extends toward the vertical center line CL as it goes forward. Neither the left front compressed portion 7a nor the right front compressed portion 7b are located extending beyond the vertical center line CL to the opposite region.

一対の前方圧搾部７は、左側前方圧搾部７ａと右側前方圧搾部７ｂとの横方向Ｙにおける距離が前方にむかうに従って狭まっていく形状となっている。このような形状とすることにより、体液が縦方向Ｘに拡散し、前方圧搾部７まで到達した場合でも、前方圧搾部７によって体液をせき止め、かつ、縦方向Ｘに拡散させつつ、横方向Ｙ内方に戻すことができ、体液を吸収体４の横方向中央部に集約させやすくなっており、横洩れ及び前方への液漏れを効果的に抑制することができる。 The pair of front compressing parts 7 have a shape in which the distance in the lateral direction Y between the left front pressing part 7a and the right front pressing part 7b narrows toward the front. By adopting such a shape, even if the body fluid diffuses in the vertical direction The body fluid can be returned inward, making it easier to collect body fluids in the lateral center of the absorber 4, and effectively suppressing side leakage and forward fluid leakage.

図４に示す形態では、左側前方圧搾部７ａ及び右側前方圧搾部７ｂは、それぞれ、前方にいくにしたがって曲率が徐々に大きくなる、緩やかに湾曲した形状を有するが、直線状であってもよい。 In the form shown in FIG. 4, the left front compressed part 7a and the right front compressed part 7b each have a gently curved shape with a curvature that gradually increases toward the front, but they may have a straight shape. .

（後方圧搾部と前方圧搾部の寸法関係）
本実施形態では、吸収体４において、吸収体後方領域Ｒは、吸収体前方領域Ｆよりも縦方向Ｘの長さが長く形成されている。これに伴い、後方圧搾部６は、前方圧搾部７よりも縦方向Ｘの長さがやや長くなる形状となっている。尚、後方圧搾部６と前方圧搾部７との縦方向Ｘの寸法の関係は本実施形態に示す形態に限定されることがなく、ナプキン１の縦方向Ｘの長さに応じて各圧搾部の縦方向Ｘの寸法を適宜設定することができる。例えば、吸収体後方領域Ｒと吸収体前方領域Ｆの縦方向Ｘの長さがほぼ同じである場合、後方圧搾部６と前方圧搾部７の縦方向Ｘの寸法が同じであってもよい。
また、本実施形態では、後方圧搾部６と前方圧搾部７との横方向Ｙの寸法はほぼ同じであるが、異なってもよく、ナプキン１の大きさや形状等に応じて適宜設定することができる。 (Dimension relationship between rear compression section and front compression section)
In this embodiment, in the absorbent body 4, the absorbent body rear region R is formed to have a longer length in the longitudinal direction X than the absorbent body front region F. Accordingly, the rear compressing section 6 has a shape that is slightly longer in the longitudinal direction X than the front compressing section 7. Incidentally, the relationship between the dimensions of the rear compressed portion 6 and the front compressed portion 7 in the longitudinal direction The dimension in the vertical direction X can be set as appropriate. For example, when the lengths in the longitudinal direction X of the absorber rear region R and the absorber front region F are approximately the same, the dimensions in the longitudinal direction X of the rear compressed portion 6 and the front compressed portion 7 may be the same.
Further, in this embodiment, the dimensions of the rear compressed portion 6 and the front compressed portion 7 in the lateral direction Y are approximately the same, but may be different, and may be set as appropriate depending on the size, shape, etc. of the napkin 1. can.

［後方切り欠きと後方圧搾部との位置関係］
図４に示すように、吸収体４において、平面視で、一対の後方圧搾部６それぞれの前端部６２ａ及び６２ｂは一対の後方切り欠き５１に挟まれた第１の領域８１に位置し、後端部６１ａ及び６１ｂは第１の領域８１よりも後方の領域に位置する。
左右一対の後方圧搾部６は、それぞれ、平面視で、第１の領域８１の位置から後方に向かって延びる線状に形成され、かつ、後方に向かうにしたがって縦中心線ＣＬ（横方向中央）に向かうように延びている。一対の後方圧搾部６それぞれの前端部６２ａ及び６２ｂは後方切り欠き５１に近接して位置する。 [Positional relationship between the rear notch and the rear compression part]
As shown in FIG. 4, in the absorbent body 4, in plan view, the front ends 62a and 62b of the pair of rear compressed parts 6 are located in the first region 81 sandwiched between the pair of rear notches 51, and the rear The ends 61a and 61b are located in a region rearward of the first region 81.
The pair of left and right rear compression portions 6 are each formed in a linear shape extending rearward from the position of the first region 81 in a plan view, and the vertical center line CL (horizontal center) extends rearward. It extends towards. Front end portions 62a and 62b of the pair of rear pressing portions 6 are located close to the rear notch 51.

ここで、吸収体後方領域Ｒは、吸収体前方領域Ｆよりも縦方向Ｘに長く形成されやすいこと、及び、着用者の動きの影響を受け易いこと等から、着用者が激しい動きをした際に、捻じれるような外力を受け易い。
このような外力の影響を緩和する観点から、吸収体４は、後方切り欠き５１と後方圧搾部６を有する。 Here, the absorber rear region R tends to be longer than the absorber front region F in the vertical direction It is susceptible to external forces such as twisting.
From the viewpoint of alleviating the influence of such external forces, the absorbent core 4 has a rear notch 51 and a rear compression section 6.

すなわち、吸収体４の後方に捩れ変形が生じた際、吸収体後方領域Ｒでは捩れ変形する際の変形の力が後方圧搾部６に沿って伝わる。該変形の力は、吸収体４において前後の領域と比較して幅が狭く捩れやすくなっている第１の領域８１で緩和され、排泄部対向領域に対応する吸収体中央領域Ｃまで伝わりにくくなる。
これにより、吸収体後方領域Ｒは、捩れ変形誘導部として機能する後方圧搾部６に沿って捩れ変形しやすくなって着用者の動きに追従して体に沿いやすくなり、装着感に優れたナプキン１とすることができる。加えて、吸収体中央領域Ｃには、後方切り欠き５１の存在によって変形の力が伝わりにくいため、吸収体中央領域Ｃは捩れ変形による影響を受けにくい。これにより、吸収体中央領域Ｃにおいて、着用者とナプキンとの間に隙間が生じにくくなり、液漏れの発生を抑制することができる。
このように、本実施形態の吸収体４では、着用者の動きが激しい場合においても、吸収体４の後方は着用者の身体に沿って変形しやすく、且つ、吸収性能の低下を防止することができる。 That is, when torsional deformation occurs at the rear of the absorbent body 4, the deformation force at the time of the torsional deformation is transmitted along the rear compressed portion 6 in the absorbent body rear region R. The deformation force is alleviated in the first region 81 of the absorbent body 4, which is narrower and more easily twisted than the front and rear regions, and is less likely to be transmitted to the absorbent body central region C corresponding to the excretion part facing region. .
As a result, the absorber rear region R easily twists and deforms along the rear compressed part 6 that functions as a torsional deformation guiding part, and follows the movements of the wearer and easily conforms to the wearer's body, making the napkin comfortable to wear. It can be set to 1. In addition, the presence of the rear notch 51 makes it difficult for the force of deformation to be transmitted to the central region C of the absorbent body, so that the central region C of the absorbent body is not easily affected by torsional deformation. As a result, a gap is less likely to be formed between the wearer and the napkin in the central region C of the absorbent body, and it is possible to suppress the occurrence of liquid leakage.
In this way, in the absorbent body 4 of this embodiment, even when the wearer moves rapidly, the rear part of the absorbent body 4 easily deforms along the wearer's body, and the absorbent performance is prevented from deteriorating. I can do it.

また、吸収体４において、左右一対の後方圧搾部６は、それぞれ、縦中心線ＣＬ（横方向中央）を超えない形状を有しており、吸収体後方領域Ｒにおいて、横方向Ｙ中央部は圧搾部が位置していない。加えて、左側後方圧搾部６ａの後端部６１ａから延長した仮想線６３ａは縦中心線ＣＬを超えて後方に延び、右側後方圧搾部６ｂの後端部６１ｂから延長した仮想線６３ｂは縦中心線ＣＬを超えて後方に延びている。
このように、吸収体４の吸収体後方領域Ｒの横方向Ｙ中央部は、圧搾されていないことで硬くなりにくく、捩れ変形時、ナプキン１と着用者との隙間が発生しにくくなり、装着感が向上するとともに後方への液漏れが効果的に抑制される。また、吸収体後方領域Ｒは、着用者の臀部の割れ目（臀裂）に対応し、圧搾されていない横方向Ｙ中央部は、捩れ変形時、上方に盛り上がりやすくなり、臀裂に入り込むように吸収体４が変形しやすくなり、ナプキン１と着用者との隙間が発生しにくい。更に、仮想線６３ａ及び仮想線６３ｂが、横方向Ｙに平行に延びず後方に延びる形状となるように後方圧搾部６を設けることにより、捩れ変形をより誘導しやすくすることができ、着用者の動きに追従して身体に沿ってより変形しやすい吸収体４とすることができる。 In addition, in the absorbent body 4, the pair of left and right rear compression portions 6 each have a shape that does not exceed the vertical center line CL (lateral center), and in the absorbent body rear region R, the horizontal Y center portion is The pressing part is not located. In addition, an imaginary line 63a extending from the rear end 61a of the left rear compressed portion 6a extends rearward beyond the vertical center line CL, and an imaginary line 63b extended from the rear end 61b of the right rear compressed portion 6b extends from the vertical center It extends rearward beyond line CL.
In this way, the center part in the lateral direction Y of the absorber rear region R of the absorbent body 4 is not compressed, so it is difficult to become hard, and when the napkin 1 is torsionally deformed, it is difficult to create a gap between the napkin 1 and the wearer. The feeling is improved and liquid leakage to the rear is effectively suppressed. In addition, the absorber rear region R corresponds to the crack in the wearer's buttocks (gluteal cleft), and the unsqueezed lateral direction Y central portion tends to bulge upward during torsional deformation and enters the intergluteal cleft. The absorbent body 4 is easily deformed, and a gap between the napkin 1 and the wearer is less likely to occur. Furthermore, by providing the rear compressed portion 6 so that the imaginary lines 63a and 63b do not extend parallel to the lateral direction Y but extend rearward, torsional deformation can be more easily induced, and the wearer The absorbent body 4 can be easily deformed along the body by following the movement of the body.

［前方切り欠きと前方圧搾部との位置関係］
図４に示すように、吸収体４において、平面視で、左右一対の前方圧搾部７それぞれの後端部７１ａ及び７１ｂは一対の前方切り欠き５２に挟まれた第２の領域８２に位置し、前端部７２ａ及び７２ｂは第２の領域８２よりも前方の領域に位置する。
左右一対の前方圧搾部７は、それぞれ、平面視で、第２の領域８２の位置から前方に向かって延びる線状に形成され、かつ、前方に向かうにしたがって縦中心線ＣＬ（横方向中央）に向かうように延びている。一対の前方圧搾部７それぞれの後端部７１ａ及び７１ｂは前方切り欠き５２に近接して位置する。 [Positional relationship between the front notch and the front compression part]
As shown in FIG. 4, in the absorbent body 4, the rear end portions 71a and 71b of the left and right front compressed portions 7 are located in the second region 82 sandwiched between the pair of front notches 52 in plan view. , the front end portions 72a and 72b are located in a region in front of the second region 82.
The left and right pair of front compressing portions 7 are each formed in a linear shape extending forward from the position of the second region 82 in plan view, and the vertical center line CL (lateral center) extends toward the front. It extends towards. Rear end portions 71a and 71b of the pair of front pressing portions 7 are located close to the front notch 52.

吸収体前方領域Ｆにおいても、吸収体後方領域Ｒと同様に、着用者が激しい動きをした際に、捻じれるような外力を受け易い。
このような外力の影響を緩和する観点から、吸収体４は、前方切り欠き５２と前方圧搾部７を有する。 Similarly to the absorber rear region R, the front region F of the absorbent body is also susceptible to external forces such as twisting when the wearer makes vigorous movements.
From the viewpoint of alleviating the influence of such external forces, the absorbent core 4 has a front notch 52 and a front compression section 7.

すなわち、吸収体４の前方に捩れ変形が生じた際、吸収体前方領域Ｆでは捩れ変形する際の変形の力が前方圧搾部７に沿って伝わる。該変形の力は、吸収体４において前後の領域と比較して幅が狭く捩れやすくなっている第２の領域８２で緩和され、排泄部対向領域に対応する吸収体中央領域Ｃまで伝わりにくくなる。
これにより、吸収体前方領域Ｆは、捩れ変形誘導部として機能する前方圧搾部７によって捩れ変形しやすくなって着用者の動きに追従して体に沿いやすく、装着感に優れたナプキン１とすることができる。加えて、吸収体中央領域Ｃでは、前方切り欠き５２の存在によって捩れ変形による影響を受けにくいため、着用者とナプキンとの間に隙間が生じにくくなり、液漏れの発生を抑制することができる。
このように、吸収体４において、前方においても、前方圧搾部及び前方切り欠きを設けることにより、前方での装着感が向上するとともに、吸収性能の低下を防止することができる。 That is, when torsional deformation occurs in the front of the absorbent body 4, the deformation force at the time of torsional deformation is transmitted along the front compressed portion 7 in the absorbent body front region F. The deformation force is alleviated in the second region 82 of the absorbent body 4, which is narrower and more easily twisted than the front and rear regions, and is less likely to be transmitted to the central region C of the absorbent body corresponding to the region facing the excretory part. .
As a result, the front area F of the absorbent body is easily twisted and deformed by the front compressed part 7 that functions as a torsional deformation guiding part, and the napkin 1 follows the movement of the wearer and easily conforms to the body, resulting in a napkin 1 that is comfortable to wear. be able to. In addition, the presence of the front notch 52 in the central region C of the absorbent body makes it less susceptible to twisting deformation, making it less likely that a gap will form between the wearer and the napkin, thereby suppressing the occurrence of liquid leakage. .
In this manner, by providing the front compressed portion and the front notch in the front part of the absorbent body 4, the feeling of wearing in the front part is improved, and a decrease in absorption performance can be prevented.

また、後方圧搾部６と同様に、左右一対の前方圧搾部７それぞれは互いに離間しており、吸収体前方領域Ｆにおいて、横方向Ｙ中央部には圧搾部は形成されていない。
このように、吸収体４の吸収体前方領域Ｆの横方向Ｙ中央部は、圧搾されていないことで硬くなりにくく、捩れ変形時、ナプキン１と着用者との隙間が発生しにくくなり、装着感が向上するとともに前方への液漏れが効果的に抑制される。 Further, like the rear compressing portion 6, the left and right pair of front compressing portions 7 are spaced apart from each other, and in the absorber front region F, no compressing portion is formed in the center portion in the lateral direction Y.
In this way, the central part in the lateral direction Y of the absorber front region F of the absorbent body 4 is not compressed and is therefore less likely to become hard, and when the napkin 1 is torsionally deformed, a gap is less likely to occur between the napkin 1 and the wearer. This improves the feeling and effectively suppresses fluid leakage to the front.

［切り欠き及び圧搾部に係る寸法例］
以下、各構成に係る寸法例について説明する。寸法は、吸収体や切り欠きの大きさや形状等によって適宜設定することができ、以下に記載する数値に限定されない。 [Example of dimensions related to notch and compressed part]
Examples of dimensions for each configuration will be described below. The dimensions can be appropriately set depending on the size and shape of the absorber and the notch, and are not limited to the numerical values described below.

捩れ変形時、後方圧搾部６に沿って伝播した変形の力を一対の後方切り欠き５１で挟まれた第１の領域８１で効果的に緩和しつつ、吸収性能を良好に維持する観点から、後方切り欠き５１の横方向Ｙの寸法は、好ましくは３ｍｍ以上、より好ましくは５ｍｍ以上であり、好ましくは１７ｍｍ以下、より好ましくは１５ｍｍ以下であり、後方切り欠き５１の縦方向Ｘの寸法は、好ましくは３ｍｍ以上、より好ましくは５ｍｍ以上であり、好ましくは２０ｍｍ以下、より好ましくは１８ｍｍ以下である。
前方切り欠き５２についても、上記後方切り欠き５１と同様の寸法とすることができる。 From the viewpoint of maintaining good absorption performance while effectively alleviating the deformation force propagated along the rear compressed portion 6 in the first region 81 sandwiched between the pair of rear notches 51 during torsional deformation, The dimension of the rear notch 51 in the horizontal direction Y is preferably 3 mm or more, more preferably 5 mm or more, and preferably 17 mm or less, more preferably 15 mm or less, and the dimension of the rear notch 51 in the vertical direction Preferably it is 3 mm or more, more preferably 5 mm or more, and preferably 20 mm or less, more preferably 18 mm or less.

捩れ変形時、後方圧搾部６に沿って伝播した変形の力を一対の後方切り欠き５１で挟まれた第１の領域８１で効果的に緩和する観点から、一対の後方圧搾部６の前端部６２ａ及び６２ｂそれぞれと、最も近接する後方切り欠き５１との距離は、好ましくは２０ｍｍ以下、より好ましくは１５ｍｍ以下である。後方切り欠き５１付近での横洩れを抑制する観点から、一対の後方圧搾部６の前端部６２ａ及び６２ｂそれぞれと、最も近接する後方切り欠き５１との距離は、好ましくは５ｍｍ以上、より好ましくは１０ｍｍ以上である。
前方圧搾部７においても、前方圧搾部７に沿って伝播した変形の力を一対の前方切り欠き５２により挟まれた第２の領域８２で効果的に緩和する観点、及び、前方切り欠き５２付近での横洩れを抑制する観点から、一対の前方圧搾部７の後端部７１ａ及び７１ｂそれぞれと、最も近接する前方切り欠き５２との距離は、上記後方圧搾部６と同様の寸法とすることができる。 From the viewpoint of effectively mitigating the deformation force propagated along the rear compressed parts 6 during torsional deformation in the first region 81 sandwiched between the pair of rear notches 51, the front ends of the pair of rear compressed parts 6 are The distance between each of 62a and 62b and the closest rear notch 51 is preferably 20 mm or less, more preferably 15 mm or less. From the viewpoint of suppressing lateral leakage near the rear notch 51, the distance between each of the front ends 62a and 62b of the pair of rear compressed parts 6 and the closest rear notch 51 is preferably 5 mm or more, more preferably It is 10 mm or more.
Also in the front compression part 7, the deformation force propagated along the front compression part 7 is effectively alleviated in the second region 82 sandwiched between the pair of front notches 52, and the vicinity of the front notch 52. From the viewpoint of suppressing lateral leakage, the distance between each of the rear ends 71a and 71b of the pair of front compressed parts 7 and the closest front notch 52 should be the same dimension as the rear compressed part 6. I can do it.

捩れ変形を誘導しつつ、ナプキン１と着用者との隙間を発生しにくくする観点から、左側後方圧搾部６ａの後端部６１ａと右側後方圧搾部６ｂの後端部６１ｂとの横方向Ｙにおける距離は、好ましくは３ｍｍ以上、より好ましくは５ｍｍ以上であり、好ましくは３５ｍｍ以下、より好ましくは３０ｍｍ以下である。
前方圧搾部７についても、捩れ変形を誘導しつつ、ナプキン１と着用者との隙間を発生しにくくする観点から、左側前方圧搾部７ａの前端部７２ａと右側前方圧搾部７ｂの前端部７２ｂとの横方向Ｙにおける距離は、上記後方圧搾部６と同様の寸法とすることができる。 In order to prevent a gap between the napkin 1 and the wearer while inducing torsional deformation, the rear end 61a of the left rear compressed part 6a and the rear end 61b of the right rear compressed part 6b are arranged in the lateral direction Y. The distance is preferably 3 mm or more, more preferably 5 mm or more, and preferably 35 mm or less, more preferably 30 mm or less.

［高剛性部について］
図４に示す吸収体４は、吸収体中央領域Ｃに高剛性部４３を有しているため、捩れ変形による吸収体中央領域Ｃでの好ましくない変形の発生がより抑制され、吸収性能がより良好に維持される。 [About high rigidity parts]
Since the absorbent body 4 shown in FIG. 4 has a high-rigidity portion 43 in the central region C of the absorbent body, the occurrence of undesirable deformation in the central region C of the absorbent body due to torsional deformation is further suppressed, and the absorption performance is further improved. Well maintained.

図４に示す例では、高剛性部４３は、第１の領域８１及び第２の領域８２と重なっていないが、図５（Ａ）～（Ｃ）に示すように、第１の領域８１又は第２の領域８２の少なくとも一方と、高剛性部４３とが平面視で重なっていてもよい。図５に示す各吸収体は、図４に示す吸収体４と比較して、高剛性部４３の平面視における大きさが異なる点でのみ相違する。以下、同様の構成については同様の符号を付し、説明を省略する。 In the example shown in FIG. 4, the high-rigidity portion 43 does not overlap with the first region 81 and the second region 82, but as shown in FIGS. At least one of the second regions 82 and the high-rigidity portion 43 may overlap in plan view. Each absorbent body shown in FIG. 5 is different from the absorbent body 4 shown in FIG. 4 only in that the size of the high-rigidity portion 43 in plan view is different. Hereinafter, similar configurations will be denoted by the same reference numerals and explanations will be omitted.

図５（Ａ）に示す吸収体４のように、平面視で、高剛性部４３の縦方向Ｘにおける後端部４３Ｒが第１の領域８１と重なっていてもよい。平面視で、後端部４３Ｒと後方圧搾部６とは離間している。
このように、吸収体中央領域Ｃと第１の領域８１を跨って高剛性部４３が位置することにより、吸収体後方領域Ｒで捩れ変形が生じた際、変形の力が吸収体中央領域Ｃまでより伝わりにくくなる。従って、排泄部対向領域である吸収体中央領域Ｃでは捩れ変形による影響をより受けにくくなり、着用者とナプキンとの間に隙間が生じにくく、液漏れがより一層抑制され得る。 Like the absorber 4 shown in FIG. 5(A), the rear end portion 43R of the high-rigidity portion 43 in the longitudinal direction X may overlap the first region 81 in plan view. In plan view, the rear end portion 43R and the rear compression portion 6 are separated from each other.
In this way, by positioning the high-rigidity portion 43 across the absorber central region C and the first region 81, when torsional deformation occurs in the absorber rear region R, the deformation force is transferred to the absorber central region C. It becomes even more difficult to convey. Therefore, the central region C of the absorbent body, which is the region facing the excretion part, is less susceptible to torsional deformation, and a gap is less likely to be formed between the wearer and the napkin, and liquid leakage can be further suppressed.

図５（Ｂ）に示す吸収体４のように、平面視で、高剛性部４３の縦方向Ｘにおける前端部４３Ｆが第２の領域８２と重なっていてもよい。平面視で、前端部４３Ｆと前方圧搾部７とは離間している。
このように、吸収体中央領域Ｃと第２の領域８２を跨って高剛性部４３が位置することにより、吸収体前方領域Ｆで捩れ変形が生じた際、変形の力が吸収体中央領域Ｃまでより伝わりにくくなる。従って、排泄部対向領域である吸収体中央領域Ｃでは捩れ変形による影響をより受けにくくなり、着用者とナプキンとの間に隙間が生じにくく、液漏れがより一層抑制され得る。 As in the absorber 4 shown in FIG. 5(B), the front end portion 43F of the high-rigidity portion 43 in the longitudinal direction X may overlap the second region 82 in plan view. In plan view, the front end portion 43F and the front compressed portion 7 are separated from each other.
In this way, by positioning the high-rigidity portion 43 across the absorber center region C and the second region 82, when torsional deformation occurs in the absorber front region F, the deformation force is transferred to the absorber center region C. It becomes even more difficult to convey. Therefore, the central region C of the absorbent body, which is the region facing the excretion part, is less susceptible to torsional deformation, and a gap is less likely to be formed between the wearer and the napkin, and liquid leakage can be further suppressed.

図５（Ｃ）に示す吸収体４のように、平面視で、高剛性部４３の縦方向Ｘにおける後端部４３Ｒ及び前端部４３Ｆそれぞれが第１の領域８１及び第２の領域８２それぞれと重なっていてもよい。平面視で、後端部４３Ｒと後方圧搾部６とは離間し、前端部４３Ｆと前方圧搾部７とは離間している。
このように、第１の領域８１、吸収体中央領域Ｃ、第２の領域８２を跨って高剛性部４３が位置することにより、吸収体後方領域Ｒ及び吸収体前方領域Ｆで捩れ変形が生じた際、変形の力が吸収体中央領域Ｃまでより伝わりにくくなる。従って、排泄部対向領域である吸収体中央領域Ｃでは捩れ変形による影響をより受けにくくなり、着用者とナプキンとの間に隙間が生じにくくなり、液漏れがより一層抑制され得る。 Like the absorbent body 4 shown in FIG. 5(C), in plan view, the rear end portion 43R and the front end portion 43F of the high rigidity portion 43 in the longitudinal direction X are respectively connected to the first region 81 and the second region 82. They may overlap. In plan view, the rear end portion 43R and the rear compressed portion 6 are separated from each other, and the front end portion 43F and the front compressed portion 7 are separated from each other.
As described above, since the high-rigidity portion 43 is located across the first region 81, the central region C of the absorbent body, and the second region 82, torsional deformation occurs in the rear region R of the absorbent body and the front region F of the absorbent body. At this time, it becomes more difficult for the force of deformation to be transmitted to the central region C of the absorber. Therefore, the central region C of the absorbent body, which is the region facing the excretion part, is less susceptible to torsional deformation, and a gap is less likely to be formed between the wearer and the napkin, and liquid leakage can be further suppressed.

＜ナプキンにおける圧搾部の構成＞
上述の吸収体４に形成される後方圧搾部６及び前方圧搾部７は、表面シート２と吸収体４とが一体的に圧搾されることによって構成されることが好ましい。すなわち、ナプキン１において、表面シート２及び吸収体４を一体的に凹陥する、後方圧搾部６を含む後方圧搾部６０と、前方圧搾部７を含む前方圧搾部７０とが設けられることが好ましい。
このような構成によれば、後方部Ｍ３及び前方部Ｍ１において、表面シート２は吸収体４の変形に追従して変形することとなり、着用者の動きに追従してナプキン１全体で捩れやすくなって身体に沿いやすくなり、より装着感に優れたナプキンとすることができる。また、表面シート２及び吸収体４を一体的に凹陥する圧搾部６０及び７０によって、ナプキン１において、吸収体４から表面シート２が浮きにくく、表面シート２から吸収体４へより速やかに液が移行されるので、吸収性能がより向上する。
このように、本実施形態のナプキン１では、着用者の動きが激しい場合においても、着用者の身体に沿って変形しやすく、且つ、吸収性能の低下を防止することができる。 <Structure of the pressing part in the napkin>
It is preferable that the rear compressed part 6 and the front compressed part 7 formed in the above-mentioned absorbent core 4 are constructed by integrally compressing the top sheet 2 and the absorbent core 4. That is, it is preferable that the napkin 1 is provided with a rear compression section 60 including the rear compression section 6 and a front compression section 70 including the front compression section 7, which integrally recess the topsheet 2 and the absorbent core 4.
According to such a configuration, in the rear part M3 and the front part M1, the top sheet 2 deforms following the deformation of the absorbent body 4, and the napkin 1 as a whole tends to twist as it follows the movement of the wearer. This allows the napkin to easily conform to the body, resulting in a napkin that is more comfortable to wear. Furthermore, due to the pressing parts 60 and 70 that integrally recess the topsheet 2 and the absorbent core 4, the topsheet 2 is less likely to float away from the absorbent core 4 in the napkin 1, and liquid flows from the topsheet 2 to the absorbent core 4 more quickly. The absorption performance is further improved.
In this way, the napkin 1 of the present embodiment can easily deform along the wearer's body even when the wearer moves rapidly, and can prevent the absorbent performance from deteriorating.

以上、本考案の実施形態について説明したが、本考案は上述の実施形態にのみ限定されるものではなく、本考案の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
例えば、以上の実施形態では、吸収性物品として生理用ナプキンの例を示したが、これに限定されない。本考案の吸収性物品は、例えば、尿取りパットやおりものシート、使い捨ておむつ等であってもよい。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that various changes can be made without departing from the gist of the present invention.
For example, in the above embodiments, a sanitary napkin was shown as an example of the absorbent article, but the absorbent article is not limited thereto. The absorbent article of the present invention may be, for example, a urine absorbing pad, a discharge sheet, a disposable diaper, or the like.

また、例えば、ナプキンは、ウイング部Ｗを有さなくてもよい。着用時に着用者の排泄部に対向する領域が、ナプキンにおける中央部、吸収体における吸収体中央領域となる。
また、例えば、上述の実施形態の吸収体及びナプキンでは、前方及び後方に切り欠き及び圧搾部を有しているが、少なくとも、前方よりも着用者の動きに強く影響を受けやすい後方に、切り欠き及び圧搾部が設けられればよい。これにより、着用者の動きに追従して、変形しやすく、且つ、吸収性能が良好な吸収体及びナプキンとすることができる。
また、例えば、上述の実施形態では、表面シートと吸収体とが一体化して凹陥された圧搾部を有するナプキンについて説明したが、表面シートと吸収体とが圧搾部によって一体化されていない構成としてもよい。 Further, for example, the napkin does not need to have the wing portion W. The area facing the wearer's excretory area when worn is the central part of the napkin and the absorbent central area of the absorbent body.
Further, for example, the absorbent body and napkin of the above-described embodiments have cutouts and compressed parts at the front and back, but at least the cutouts and compressed parts at the back are more likely to be affected by the movement of the wearer than at the front. It is sufficient if a notch and a compressed portion are provided. Thereby, it is possible to obtain an absorbent body and a napkin that can easily deform to follow the movements of the wearer and have good absorption performance.
Furthermore, for example, in the above-described embodiment, a napkin is described in which the top sheet and the absorbent body are integrated and have a recessed compressed part. Good too.
