<<<< Basic configuration of pants-type disposable diapers >>>>
FIG. 1A is a schematic perspective view of a pants-type disposable diaper 1. Drawing 1B is a figure showing an example of the wearing state of diaper 1. FIG. 2 is a schematic plan view of the diaper 1 in an unfolded state and an extended state as viewed from the skin side. FIG. 3 is a schematic sectional view taken along the line AA in FIG. FIG. 4 is a schematic sectional view taken on line BB in FIG. The "deployed state" means that the joining of the side portion 20a of the abdominal waistline portion 20 and the side portion 30a of the back waistline portion 30 on both sides of the diaper 1 is separated, and the entire diaper 1 is opened in a planar manner. It is in the expanded state. The “extended state” indicates a state in which the elastic member provided in the diaper 1 is extended to such an extent that wrinkles of the diaper 1 cannot be visually recognized. Specifically, it shows a state in which the dimensions of each member (for example, the belly-side waist portion 20 described later) constituting the diaper 1 are elongated until the size of the member matches or is close to the size of the single member. The line CC in FIG. 2 is a center line in the left-right direction. In FIG. 3, the adhesive is omitted for convenience.

図１に示すように、パンツ型のおむつ１は上下方向と左右方向と前後方向とを有し、おむつ１には胴回り開口部ＢＨ及び一対の脚回り開口部ＬＨが形成されている。上下方向において、胴回り開口部ＢＨ側を上側とし、着用者の股下となる側を下側とする。図２の状態（展開かつ伸長状態）のおむつ１の上下方向を「長手方向」、長手方向の一方側を「腹側」、他方側を「背側」ともいい、長手方向における中央部Ｃ１０側を「下側」ともいう。前後方向において、着用者の腹側となる側を前側とし、着用者の背側となる側を後側とする。また、おむつ１は図３に示すように厚さ方向を有し、厚さ方向において着用者に接触する側を肌側とし、その逆側を非肌側とする。   As shown in FIG. 1, the pants-type diaper 1 has an up-down direction, a left-right direction, and a front-rear direction, and the diaper 1 has a waist opening BH and a pair of leg openings LH. In the up-down direction, the waist opening BH side is the upper side, and the side that becomes the crotch of the wearer is the lower side. The up-down direction of the diaper 1 in the state of FIG. 2 (deployed and extended state) is also referred to as a “longitudinal direction”, one side in the longitudinal direction is referred to as a “ventral side”, and the other side is referred to as a “dorsal side”. Is also referred to as “lower side”. In the front-rear direction, the side that is the abdomen of the wearer is the front side, and the side that is the back of the wearer is the rear side. In addition, the diaper 1 has a thickness direction as shown in FIG. 3, the side in contact with the wearer in the thickness direction is the skin side, and the opposite side is the non-skin side.

おむつ１は、所謂３ピースタイプであり、吸収性本体１０と腹側胴回り部２０、背側胴回り部３０とを有する。腹側胴回り部２０は、着用者の腹側を覆い、背側胴回り部３０は、着用者の背側を覆う。吸収性本体１０は平面視略長方形形状である。図３に示すように、吸収性本体１０の腹側の上端部と背側の上端部は、それぞれ胴回り部２０、３０の肌側面と重ね合されている。腹側胴回り部２０、背側胴回り部３０は平面視略長方形状であり、その長手方向が左右方向に沿っている。   The diaper 1 is a so-called three-piece type, and has an absorbent main body 10, an abdominal waistline 20, and a back waistline 30. The abdominal girth 20 covers the wearer's abdomen, and the dorsal girth 30 covers the wearer's back. The absorbent main body 10 has a substantially rectangular shape in plan view. As shown in FIG. 3, the upper end on the abdomen side and the upper end on the back side of the absorbent main body 10 are overlapped with the skin side surfaces of the waist parts 20 and 30, respectively. The abdominal waistline portion 20 and the back waistline portion 30 are substantially rectangular in plan view, and their longitudinal directions extend in the left-right direction.

図２の展開状態にて示されるように、おむつ１は、中心線Ｃ−Ｃに対して左右対称な形状を有している。吸収性本体１０の腹側の上端部、及び背側の上端部のそれぞれ非肌側面と胴回り部２０、３０の肌側面とを接着剤等（不図示）により接合し、図２に示す展開状態から、腹側胴回り部２０と背側胴回り部３０とが対向するように吸収性本体１０を中央部Ｃ１０で二つ折りし、腹側胴回り部２０の左右方向の両側部２０ａと背側胴回り部３０の左右方向の両側部３０ａとを接合することにより、おむつ１はパンツ型となる。   2, the diaper 1 has a symmetrical shape with respect to the center line CC. The non-skin side surfaces of the abdominal upper end portion and the dorsal upper end portion of the absorbent main body 10 and the skin side surfaces of the girth portions 20 and 30 are joined by an adhesive or the like (not shown), and are shown in the unfolded state shown in FIG. From above, the absorbent main body 10 is folded in two at the central portion C10 such that the abdominal waistline portion 20 and the back waistline portion 30 face each other, and both side portions 20a of the abdominal waistline portion 20 in the left-right direction and the back waistline portion 30 The diaper 1 becomes a pants-type by joining the side portions 30a in the left-right direction of the diaper.

腹側胴回り部２０及び背側胴回り部３０はそれぞれ、不織布等の柔軟な肌側シート２１、３１と非肌側シート２２、３２と、胴回り伸縮部材２３、３３とを備える。胴回り伸縮部材２３、３３によって、腹側胴回り部２０及び背側胴回り部３０は伸縮可能となり、着用者の胴回りにフィットする。肌側シート２１、３１及び非肌側シート２２、３２は、各シート単体としては、左右方向に伸縮性を実質的に有さない非伸縮シートである。肌側シート２１、３１及び非肌側シート２２、３２としては、ＳＭＳ不織布（スパンボンド・メルトブローン・スパンボンド不織布）、スパンボンド不織布、エアスルー不織布、プラスチックシート、開孔プラスチックシート及びそれらのラミネートシート等を用いることができる。   The abdominal waistline portion 20 and the back waistline portion 30 include flexible skin-side sheets 21 and 31 such as nonwoven fabric, non-skin-side sheets 22 and 32, and waistline elastic members 23 and 33, respectively. By the waist elastic members 23 and 33, the abdominal waist portion 20 and the back waist portion 30 can expand and contract, and fit around the wearer's waist. The skin-side sheets 21 and 31 and the non-skin-side sheets 22 and 32 are non-stretchable sheets that have substantially no elasticity in the left-right direction as a single sheet. Examples of the skin-side sheets 21 and 31 and the non-skin-side sheets 22 and 32 include an SMS nonwoven fabric (spunbond / meltblown / spunbond nonwoven fabric), a spunbond nonwoven fabric, an air-through nonwoven fabric, a plastic sheet, a perforated plastic sheet, and a laminate sheet thereof. Can be used.

腹側胴回り伸縮部材２３は、左右に伸縮する複数の糸ゴム２３ａと上下及び左右方向に伸縮する伸縮シート２３ｂである。糸ゴム２３ａは、肌側シート２１と非肌側シート２２との間で、且つ、腹側胴回り部２０の上端部を除く全域に上下方向に間隔を空けて、左右方向に伸長した状態で固定されている。伸縮シート２３ｂは、非肌側から肌側に折り返された非肌側シート２２と肌側シート２１との間で、吸収性本体１０よりも非肌側に配置され、且つ、腹側胴回り部２０の上端部に、左右方向に伸長した状態で固定されている。伸縮シート２３ｂは、弾性を有する熱可塑性エラストマー性繊維であるポリウレタン系エラストマーと、非弾性を有する熱可塑性樹脂性繊維であるポリオレフィン系樹脂のポリプロピレン（ＰＰ）とを有する、ギア延伸等の適宜な延伸処理が施された不織布やプラスチック製の伸縮性を有するフィルムシート等である。   The abdominal waist elastic member 23 is a plurality of thread rubbers 23a that expand and contract in the left and right directions and an elastic sheet 23b that expands and contracts in the vertical and horizontal directions. The thread rubber 23a is fixed between the skin-side sheet 21 and the non-skin-side sheet 22 and extended in the left-right direction at intervals in the vertical direction over the entire region except the upper end of the abdominal waistline portion 20. Have been. The stretchable sheet 23b is disposed on the non-skin side of the absorbent body 10 between the non-skin side sheet 22 and the skin side sheet 21 folded from the non-skin side to the skin side, and the abdominal waist portion 20 Is fixed to the upper end portion in a state of extending in the left-right direction. The stretch sheet 23b is appropriately stretched, such as gear stretching, having a polyurethane-based elastomer that is a thermoplastic elastomeric fiber having elasticity and a polypropylene (PP) of a polyolefin-based resin that is a thermoplastic resinous fiber having inelasticity. Examples include a treated nonwoven fabric and a plastic film sheet having elasticity.

このように、腹側胴回り部２０の上端部に糸ゴム２３ａを配置せずに伸縮シート２３ｂを配置することで、腹側胴回り部２０の上端部が面で着用者にフィットする。そのため、腹部の局所的な締め付けを抑え、腹側胴回り伸縮部材２３によって肌に締め付けた跡が残り難くすることができる。特に、乳幼児の腹部は、背側に比べて前にせり出しているため、腹側胴回り２０が局所的に締め付けてしまう恐れを軽減することがより好ましい。   By arranging the elastic sheet 23b without arranging the thread rubber 23a on the upper end of the abdominal waistline 20 in this way, the upper end of the abdominal waistline 20 fits the wearer in a plane. Therefore, local tightening of the abdomen can be suppressed, and traces of tightening on the skin by the abdominal waist elastic member 23 can be less likely to remain. In particular, since the abdomen of the infant protrudes forward as compared to the back, it is more preferable to reduce the possibility that the abdominal waistline 20 is locally tightened.

背側胴回り伸縮部材２３は、背側胴回り部３０の上端部から下端部に亘って上下方向に間隔を空けて配された、左右方向に伸縮する複数の糸ゴム３３であり、肌側シート３１と非肌側シート３２との間に左右方向に伸長した状態で固定されている。   The back-side waist elastic member 23 is a plurality of thread rubbers 33 that extend and contract in the left-right direction and are arranged at intervals in the up-down direction from the upper end to the lower end of the back-side waist portion 30. And the non-skin side sheet 32 is fixed in a state of extending in the left-right direction.

なお、腹側胴回り部２０及び背側胴回り部３０は、それぞれ腹側胴回り伸縮部材２３及び背側胴回り伸縮部材３３とともに伸縮する伸縮領域Ｄｆ、Ｄｂと、腹側胴回り伸縮部材２３及び背側胴回り伸縮部材３３とともに伸縮しない非伸縮領域Ｆｆ、Ｆｂを有する。図８は、伸縮領域Ｄｆ、Ｄｂと非伸縮領域Ｆｆ、Ｆｂを説明する図である。図８において、右斜め下のハッチングで伸縮領域Ｄｆ、Ｄｂを示し、左斜め下のハッチングで非伸縮領域Ｆｆ、Ｆｂを示している。非伸縮領域Ｆｆ、Ｆｂは、腹側胴回り部２０及び背側胴回り部３０のそれぞれ左右方向の中央部で、吸収性コア１１Ａと前後方向で重なる領域に設けられている。非伸縮領域Ｆｆ、Ｆｂを設けることで、伸縮部材２３、３３の収縮によって吸収性コア１１Ａが左右方向に縮められて変形してしまう恐れを軽減している。   In addition, the abdominal waistline portion 20 and the back waistline portion 30 include elastic regions Df and Db that expand and contract with the abdominal waistline elastic member 23 and the backside waistline elastic member 33, respectively, and the abdominal waistline elastic member 23 and the back waistline elastic member. It has non-stretchable regions Ff and Fb which do not expand and contract with the member 33. FIG. 8 is a diagram illustrating the stretchable regions Df and Db and the non-stretchable regions Ff and Fb. In FIG. 8, the diagonally lower right hatching indicates the stretchable regions Df and Db, and the diagonally lower left hatching indicates the non-stretchable regions Ff and Fb. The non-stretchable areas Ff and Fb are provided in the left and right central portions of the abdominal waistline portion 20 and the back waistline portion 30, respectively, in regions that overlap the absorbent core 11A in the front-rear direction. By providing the non-stretchable regions Ff and Fb, the possibility that the absorbent core 11A is shrunk in the left-right direction and deformed by contraction of the stretchable members 23 and 33 is reduced.

図４は、図２中のＢ−Ｂ矢視で示す概略断面図である。図４は、厚さ方向に関して構成を理解しやすいように寸法を適宜変更して示している。図４に示すように、吸収性本体１０は、厚さ方向の肌側から順に、一対の防漏壁部材１５、トップシート１２、吸収体１１と、バックシート１３、外装シート１４とを備え、それぞれホットメルト等の接着剤によって接着されている。トップシート１２は液透過性シートであればよく、親水性のエアスルー不織布やスパンボンド不織布等を例示できる。バックシート１３は液不透過性シートであればよく、ポリエチレンフィルムやポリプロピレンフィルム、疎水性のＳＭＳ不織布等を例示できる。トップシート１２及びバックシート１３は吸収体１１全体を覆う大きさとする。防漏壁部材１５及び外装シート１４は、液透過性シートでも液不透過性シートでもよく、疎水性のＳＭＳ不織布等を例示できる。ただし、本実施形態では防漏壁部材１５及び外装シート１４によって防漏壁部５０及びレッグギャザー部６０がそれぞれ形成されるため、防漏壁部材１５及び外装シート１４は液不透過性の素材で構成されることが好ましい。   FIG. 4 is a schematic sectional view taken on line BB in FIG. FIG. 4 shows dimensions appropriately changed so that the configuration can be easily understood in the thickness direction. As shown in FIG. 4, the absorbent main body 10 includes a pair of leakage prevention wall members 15, a top sheet 12, an absorber 11, a back sheet 13, and an exterior sheet 14 in order from the skin side in the thickness direction. Each is bonded by an adhesive such as hot melt. The top sheet 12 may be a liquid permeable sheet, and examples thereof include a hydrophilic air-through nonwoven fabric and a spunbonded nonwoven fabric. The back sheet 13 may be a liquid impermeable sheet, and examples thereof include a polyethylene film, a polypropylene film, and a hydrophobic SMS nonwoven fabric. The top sheet 12 and the back sheet 13 are large enough to cover the entire absorber 11. The leak preventing wall member 15 and the exterior sheet 14 may be a liquid-permeable sheet or a liquid-impermeable sheet, and examples thereof include a hydrophobic SMS nonwoven fabric. However, in the present embodiment, since the leak preventing wall portion 50 and the leg gather portion 60 are formed by the leak preventing wall member 15 and the exterior sheet 14, respectively, the leak preventing wall member 15 and the exterior sheet 14 are made of a liquid impermeable material. Preferably, it is configured.

吸収体１１は、平面視略矩形形状であり、尿等の液体を吸収して保持する吸収性コア１１Ａと、吸収性コア１１Ａの外周面を被覆するコアラップシート１１Ｂとを備える。図５は、吸収体１１を説明する図である。コアラップシート１１Ｂとしては、ティッシュペーパーや不織布等の液透過性シートを例示できる。図５において、便宜上、コアラップシート１１Ｂに覆われた吸収性コア１１Ａを実線で示している。   The absorber 11 has a substantially rectangular shape in a plan view, and includes an absorbent core 11A that absorbs and holds liquid such as urine, and a core wrap sheet 11B that covers the outer peripheral surface of the absorbent core 11A. FIG. 5 is a diagram illustrating the absorber 11. As the core wrap sheet 11B, a liquid permeable sheet such as a tissue paper or a nonwoven fabric can be exemplified. In FIG. 5, for convenience, the absorbent core 11A covered with the core wrap sheet 11B is shown by a solid line.

吸収性コア１１Ａは、高吸収性ポリマー（ＳＡＰ）を含むパルプ等の液体吸収性繊維を略砂時計形状に成形されたものである。本実施形態において、吸収性コア１１Ａの液体吸収性繊維の坪量は、吸収性コア１１Ａ全域において略均一である。吸収性コア１１Ａのうち、中央部Ｃ１０より腹側（前側）に位置する部分は前側コア部１１Ａｆであり、中央部Ｃ１０より背側（後側）に位置する部分は後側コア部１１Ａｂである。図５等に示すように、吸収性コア１１Ａの長手方向の中央部を左右方向の長さを短くし、くびれさせている。具体的には、前側コア部１１Ａｆの上部１１ｆｕより下側に前側幅狭部（「幅狭部」ともいう。）１１ｆｎと、後側コア部１１Ａｂの上部１１ｂｕより下側に後側幅狭部１１ｂｎを設けている。前側幅狭部１１ｆｎの長手方向の長さは、後側幅狭部１１ｂｎの長手方向の長さよりも長い。また、吸収性コア１１Ａの左右方向の長さが一番短い部分である最狭部１１ｎは、前側コア部１１Ａｆの幅狭部１１ｆｎに設けられている。前側コア部１１Ａｆに、前側幅狭部１１ｆｎを設けることで、脚を前側に出した姿勢でいることが多い乳幼児が着用して、左右方向に脚を閉じた場合であっても、吸収性コア１１Ａが脚の動きを妨げる恐れを軽減させることができる。   The absorbent core 11A is formed by molding a liquid absorbent fiber such as pulp containing a highly absorbent polymer (SAP) into a substantially hourglass shape. In the present embodiment, the basis weight of the liquid absorbent fibers of the absorbent core 11A is substantially uniform over the entire area of the absorbent core 11A. In the absorbent core 11A, a portion located on the ventral side (front side) from the central portion C10 is the front core portion 11Af, and a portion located on the dorsal side (rear side) from the central portion C10 is the rear core portion 11Ab. . As shown in FIG. 5 and the like, the central portion in the longitudinal direction of the absorbent core 11A is reduced in length in the left-right direction and narrowed. Specifically, a front narrow portion (also referred to as a “narrow portion”) 11fn below the upper portion 11fu of the front core portion 11Af, and a rear narrow portion below the upper portion 11bu of the rear core portion 11Ab. 11bn are provided. The longitudinal length of the front narrow portion 11fn is longer than the longitudinal length of the rear narrow portion 11bn. Further, the narrowest portion 11n, which is the portion where the length in the left-right direction of the absorbent core 11A is the shortest, is provided in the narrow portion 11fn of the front core portion 11Af. The front core portion 11Af is provided with the front narrow portion 11fn so that the absorbent core can be worn even when the child is often worn in a posture in which the leg is put forward and the leg is closed in the left-right direction. 11A can reduce the risk of hindering the movement of the leg.

さらに、吸収性コア１１Ａには、左右方向に沿った形状の圧搾部Ｅが、上下方向に所定の間隔毎に複数設けられている。圧搾部Ｅについては、後述する。また、後側コア部１１Ａｂに、厚さ方向（前後方向）に貫通したスリット（貫通孔）Ｓを備えることで、吸収性コア１１Ａが着用者のお尻の形状に沿いやすくしている。   Further, the absorbent core 11A is provided with a plurality of compressed portions E having a shape extending in the left-right direction at predetermined intervals in the up-down direction. The pressing unit E will be described later. Further, by providing the rear core portion 11Ab with a slit (through hole) S penetrating in the thickness direction (front-rear direction), the absorbent core 11A can easily follow the shape of the wearer's hips.

一対の防漏壁部材１５は、一対の防漏壁部５０を構成する。一対の防漏壁部５０は、所謂立体ギャザーであり、吸収性本体１０の長手方向に沿って、吸収体１１の左右方向の両側部に設けられている。具体的には、複数の防漏壁伸縮部材５１を内側に挟んだ状態で二つ折りされた防漏壁部材１５の折り目部分を左右方向の内側に配置し、吸収性本体１０の左右方向の側端から吸収体１１の左右方向の側部に重ね合される位置まで設けている。   The pair of leakage preventing wall members 15 constitute a pair of leakage preventing wall portions 50.

The end joining portion 52 is provided from the end of the absorbent main body 10 to a position overlapping the upper end of the absorber 11 in the longitudinal direction. The pair of side joints 53 are provided from one end to the other end in the longitudinal direction of the absorbent main body 10 and those provided from the ventral end of the absorbent main body 10 to the central portion C10 in the longitudinal direction. There is. Each is arranged outside the end joining part 52 in the left-right direction.

防漏壁部５０は、防漏壁伸縮部材５１の収縮によって、サイド接合部５３に左右方向内側から隣接する部分を基点に起立部５６が肌側に起立可能となる。なお、複数本の防漏壁伸縮部材５１をそれぞれ離間させて設けることで、防漏壁部５０の起立状態では、着用者の肌に防漏壁部５０を面で接触させやすくなり、肌触りを向上させることができる。   Due to the contraction of the leak-preventing wall expandable member 51, the leak-preventing wall portion 50 becomes capable of standing upright on the skin side from a portion adjacent to the side joint portion 53 from the inside in the left-right direction. By providing the plurality of leak-preventing wall expandable members 51 at a distance from each other, the leak-preventing wall 50 can be easily brought into contact with the wearer's skin in a standing state when the leak-preventing wall 50 is in an upright state, and the touch is improved. Can be improved.

外装シート１４は、脚回り伸縮部材１６を備えた一対のレッグギャザー部６０を構成する。レッグギャザー部６０は、脚回り開口部ＬＨを形成する部分であり、脚回り伸縮部材１６の収縮により着用者の脚にフィットする。   The exterior sheet 14 forms a pair of leg gathers 60 provided with the leg elastic members 16. The leg gather portion 60 is a portion forming the leg opening LH, and fits the wearer's leg by contraction of the leg elastic member 16.

左右方向の両端部が内側に折り返されており、折り返された外装シート１４同士の間に脚回り伸縮部材１６を配置して、レッグギャザー部６０を構成する。脚回り伸縮部材１６は、長手方向に沿った複数本の糸ゴムであり、左右方向の内側に折り返されて２層となった外装シート１４の間に、吸収性本体１０の長手方向に伸長された状態で固定されている。   Both ends in the left-right direction are folded inward, and the leg elastic members 16 are arranged between the folded exterior sheets 14 to form the leg gather portion 60. The leg elastic member 16 is a plurality of thread rubbers extending in the longitudinal direction, and is extended in the longitudinal direction of the absorbent main body 10 between the exterior sheets 14 which are folded inward in the left-right direction to form two layers. It is fixed in the state where it was set.

脚回り伸縮部材１６として糸ゴムを用いる場合、複数本配置することが好ましく、より好ましくは５本以上配置することがよい。図２等においては、８本の脚回り伸縮部材１６を左右方向に並べて配置している。仮に脚回り伸縮部材１６が１本の場合には、着用者の脚を局所的に締め付けてしまう恐れがあるが、脚回り伸縮部材１６をより多く設けることで、レッグギャザー部６０は全体的に面でフィットしやすくなり、着用者の脚を局所的に締め付けてしまう恐れを軽減させることができる。   When thread rubber is used as the leg elastic member 16, it is preferable to arrange a plurality of thread rubbers, more preferably five or more. In FIG. 2 and the like, eight leg elastic members 16 are arranged side by side in the left-right direction. If there is only one leg elastic member 16, the leg of the wearer may be locally tightened. However, by providing more leg elastic members 16, the leg gather portion 60 is entirely formed. This makes it easier to fit the surface, and can reduce the risk of locally tightening the wearer's leg.

上述のとおり、腹側胴回り部２０及び背側胴回り部３０は、それぞれ左右方向に伸縮する伸縮部材２３、３３を備えているため、着用者である乳幼児の動きに応じて、伸縮部材２３、３３が伸縮することで、乳幼児の胴回りにフィットさせている。一方、吸収性本体１０は、左右方向に伸縮する伸縮部材を備えていない。そのため、乳幼児が動いて腹側胴回り部２０と背側胴回り部３０が、その動きに追従したとしても、吸収性本体１０は、腹側胴回り部２０及び背側胴回り部３０ほどには追従しづらく、乳幼児が身体を動かすと、吸収性本体１０の中央部が非肌側に浮いてしまって、乳幼児の身体から離れてしまう恐れがある。特に、図１Ａ等に示すおむつ１においては、腹側胴回り部２０及び背側胴回り部３０のそれぞれ左右方向の中央部で、吸収性コア１１Ａと前後方向で重なる領域に設けられた非伸縮領域Ｆｆ、Ｆｂは左右方向に伸縮しないため、図１Ｂに示すように脚を前に出した姿勢でいる乳幼児が脚を動かすと、吸収性本体１０のうち、吸収性コア１１Ａの非伸縮領域Ｆｆ、Ｆｂと前後方向で重なる非伸縮領域Ｌの吸収性本体１０の左右方向の中央部が非肌側に浮いてしまう恐れがある。この場合、吸収性本体１０の左右方向の中央部から上側に向かって***物が漏れてしまう恐れを生じてしまう。   As described above, since the abdominal waistline portion 20 and the back waistline portion 30 include the elastic members 23 and 33 that expand and contract in the left-right direction, respectively, the elastic members 23 and 33 according to the movement of the baby who is the wearer. By expanding and contracting, it fits around the torso of infants. On the other hand, the absorbent main body 10 does not include an elastic member that expands and contracts in the left-right direction. Therefore, even if the infant moves and the abdominal waistline portion 20 and the back waistline portion 30 follow the movement, the absorbent main body 10 is hard to follow as much as the abdominal waistline portion 20 and the back waistline portion 30. When the infant moves his or her body, the central part of the absorbent main body 10 may float on the non-skin side and may be separated from the infant's body. In particular, in the diaper 1 shown in FIG. 1A and the like, the non-stretchable region Ff provided in a region overlapping the absorbent core 11A in the front-rear direction at the center in the left-right direction of the abdominal waistline portion 20 and the back waistline portion 30. , Fb do not expand and contract in the left-right direction, and when the infant moves the legs as shown in FIG. 1B, the non-stretchable regions Ff, Fb of the absorbent core 11A of the absorbent main body 10 move. There is a possibility that the central part in the left-right direction of the absorbent main body 10 of the non-stretchable region L overlapping in the front-back direction may float on the non-skin side. In this case, there is a possibility that excrement may leak upward from the central portion of the absorbent body 10 in the left-right direction.

吸収性本体１０が乳幼児の身体から離れてしまう恐れを軽減させるために、おむつ１の吸収性コア１１Ａに圧搾部Ｅを設けている。以下、圧搾部Ｅについて説明する。   The squeezing portion E is provided on the absorbent core 11A of the diaper 1 in order to reduce the risk that the absorbent main body 10 is separated from the body of the baby. Hereinafter, the pressing unit E will be described.

＝＝＝圧搾部Ｅ＝＝＝
圧搾部Ｅは、複数の突部を有する凸ローラー（不図示）と、表面が平らなアンビルローラー（不図示）とのあいだのロール間隙に、加工前の吸収性コア１１Ａを通して、吸収性コアの非肌側から圧搾加工を行うことにより形成される。図７Ｂは、図７Ａ中のＸ−Ｘ矢視で示す領域における吸収性コア１１Ａの概略断面図である。吸収性コア１１Ａのうち、圧搾加工を行っていない領域は、非圧搾部Ｕである。 === Squeezed part E ===
The squeezing section E is formed by passing an absorbent core 11A before processing into a roll gap between a convex roller (not shown) having a plurality of protrusions and an anvil roller (not shown) having a flat surface. It is formed by pressing from the non-skin side. FIG. 7B is a schematic cross-sectional view of the absorbent core 11A in a region indicated by arrows XX in FIG. 7A. In the absorbent core 11A, a region where the pressing process is not performed is the non-pressed portion U.

圧搾部Ｅは、圧搾によって形成された溝であり、非圧搾部Ｕよりもパルプ等の液体吸収性繊維の密度が高く、非圧搾部Ｕよりも剛性が高い。本実施形態において、圧搾部Ｅの溝の深さは略均一である。溝の深さによって、液体吸収性繊維の密度が変化し、溝が深いほど液体吸収性繊維の密度が高くなり、溝が浅いほど液体吸収性繊維の密度が低くなる。図５等に示すように、圧搾部Ｅは左右方向に沿った形状であり、左右方向の長さＷｅは７０ｍｍ、圧搾部Ｅの上下方向の長さＤｅは３ｍｍであり、圧搾部Ｅは上下方向に等間隔に配置されており、上下方向に隣接する圧搾部Ｅ同士の間隔Ｄｕは１０ｍｍである。また、圧搾部Ｅの左右方向の中央は、吸収性コア１１Ａの中央であり、吸収性コア１１Ａは左右対称な形状である。   The pressed portion E is a groove formed by pressing, and has a higher density of liquid absorbent fibers such as pulp than the non-pressed portion U, and has a higher rigidity than the non-pressed portion U. In the present embodiment, the depth of the groove of the compressed portion E is substantially uniform. The density of the liquid-absorbent fiber changes depending on the depth of the groove. The deeper the groove, the higher the density of the liquid-absorbent fiber, and the shallower the groove, the lower the density of the liquid-absorbent fiber. As shown in FIG. 5 and the like, the pressed portion E is shaped along the left-right direction, the length We in the left-right direction is 70 mm, the length De in the vertical direction of the pressed portion E is 3 mm, and the pressed portion E is Are arranged at equal intervals in the direction, and the interval Du between the squeezed portions E vertically adjacent to each other is 10 mm. The center in the left-right direction of the compressed portion E is the center of the absorbent core 11A, and the absorbent core 11A has a left-right symmetric shape.

非圧搾部Ｕは、圧搾部Ｅよりも厚みが大きい。そのため、吸収性コア１１Ａは、非肌側面に凸部と凹部を有することが好ましい。図７Ｂに示すように、吸収性コア１１Ａは、肌側面は概ね平らであり、非肌側面に凸部と凹部を有する。凸部が非圧搾部Ｕであり、凹部が圧搾部Ｅである。このようにすることで、パンツ型のおむつ１の吸収性コア１１Ａの肌側を内側にして、長手方向の中央部で二つ折りにした際に、吸収性コア１１Ａの肌側面で吸収性コア１１Ａの凸部と凹部が干渉し合って吸収性コア１１Ａを曲がりにくくなるのを防ぐことができる。また、肌側面を概ね平らにすることで、着用者に吸収性コア１１Ａの凸凹や剛性の高い圧搾部Ｅによる違和感を生じさせる恐れを軽減させることができる。   The non-squeezed portion U is thicker than the pressed portion E. Therefore, it is preferable that the absorbent core 11A has a convex portion and a concave portion on the non-skin side surface. As shown in FIG. 7B, the absorbent core 11A has a substantially flat skin side surface, and has a convex portion and a concave portion on a non-skin side surface. The convex portion is the non-pressed portion U, and the concave portion is the pressed portion E. In this way, when the skin side of the absorbent core 11A of the pants-type diaper 1 is turned inside and the absorbent core 11A is folded in two at the center in the longitudinal direction, the absorbent core 11A is placed on the skin side of the absorbent core 11A. Can be prevented from interfering with each other and causing the absorbent core 11A to be difficult to bend. In addition, by making the skin side substantially flat, it is possible to reduce the risk of causing the wearer to feel uncomfortable due to the unevenness of the absorbent core 11A and the compressed portion E having high rigidity.

図２等に示すように、吸収性コア１１Ａには、腹側胴回り部２０と背側胴回り部３０と前後方向においてそれぞれ重なる重なり領域１１Ｐｆ、重なり領域１１Ｐｂと、それぞれ重ならない非重なり領域１１Ｑｆ、非重なり領域１１Ｑｂを有している。そして、重なり領域１１Ｐｆ、重なり領域１１Ｐｂには、それぞれ圧搾部Ｅが設けて、左右方向の剛性を向上させている。これによって、剛性が向上した重なり領域１１Ｐｆ及び重なり領域１１Ｐｂは、左右方向の平面形状を維持しやすくなっている。吸収性コア１１Ａのうち、乳幼児の動きによって非肌側に浮いてしまう恐れのある重なり領域１１Ｐｆと重なり領域１１Ｐｂの左右方向の剛性を上げることで、乳幼児が動いた場合でも、吸収性コア１１Ａは、左右方向に沿った平面形状を維持しやすく、吸収性本体１０を乳幼児の身体にフィットさせた状態を維持しやすくなる。この結果、吸収性本体１０の左右方向の中央部における上端から上側に向かって***物が漏れてしまう恐れを軽減させることができる。   As shown in FIG. 2 and the like, the absorbent core 11A has an overlapping region 11Pf that overlaps the abdominal waist portion 20 and the back waist portion 30 in the front-rear direction, a non-overlapping region 11Qf that does not overlap with the overlapping region 11Pb, and a non-overlapping region 11Qf. It has an overlapping area 11Qb. Then, a pressing portion E is provided in each of the overlapping region 11Pf and the overlapping region 11Pb to improve rigidity in the left-right direction. As a result, the overlapping region 11Pf and the overlapping region 11Pb having improved rigidity can easily maintain a horizontal plane shape. In the absorbent core 11A, by increasing the rigidity in the left-right direction of the overlapping region 11Pf and the overlapping region 11Pb which may float on the non-skin side due to the movement of the baby, even when the baby moves, the absorbent core 11A It is easy to maintain the planar shape along the left-right direction, and it is easy to maintain the state in which the absorbent main body 10 is fitted to the body of the baby. As a result, it is possible to reduce the risk of excrement leaking upward from the upper end of the absorbent body 10 in the central portion in the left-right direction.

なお、本実施形態においては、重なり領域１１Ｐｆと重なり領域１１Ｐｂの両方に圧搾部Ｅを設けたが、いずれか一方の領域に圧搾部Ｅを設けるものであってもよい。例えば、乳幼児は脚を前側に出した姿勢でいるため、より変形が多く起こる傾向のある腹側の重なり領域１１Ｐｆにのみ圧搾部Ｅを設けるものであってもよい。ただし、重なり領域１１Ｐｆ及び重なり領域１１Ｐｂの両方に圧搾部Ｅを設けることで、腹側及び背側の両方の吸収性本体１０が非肌側に浮いてしまう恐れを軽減させるため、吸収性本体１０を乳幼児の身体によりフィットさせやすくなる。   In the present embodiment, the compressed portion E is provided in both the overlapping region 11Pf and the overlapping region 11Pb, but the compressed portion E may be provided in any one of the regions. For example, since the infant is in a posture in which the legs are put forward, the squeezed portion E may be provided only in the overlapping region 11Pf on the abdominal side where deformation is more likely to occur. However, by providing the squeezed portions E in both the overlapping region 11Pf and the overlapping region 11Pb, it is possible to reduce the possibility that both the abdominal and back absorbent bodies 10 float on the non-skin side. More easily fit the baby's body.

また、図２等においては、複数の圧搾部Ｅを長手方向に並べて配置したが、圧搾部Ｅは、重なり領域１１Ｐｆ又は重なり領域１１Ｐｂに少なくとも１つ設けるものでもよい。１つの圧搾部Ｅであっても重なり領域１１Ｐｆ又は重なり領域１１Ｐｂの左右方向の剛性を向上させることができる。ただし、図２等に示すように、吸収性コア１１Ａに複数の圧搾部Ｅを設けることで、左右方向の剛性をより向上させることができる。   Further, in FIG. 2 and the like, the plurality of squeezed portions E are arranged side by side in the longitudinal direction. However, at least one squeezed portion E may be provided in the overlapping region 11Pf or the overlapping region 11Pb. Even with one pressing portion E, the rigidity of the overlapping region 11Pf or the overlapping region 11Pb in the left-right direction can be improved. However, as shown in FIG. 2 and the like, by providing a plurality of compressed portions E in the absorbent core 11A, the rigidity in the left-right direction can be further improved.

さらに、図２等に示すように、複数の圧搾部Ｅを上下方向に等間隔に配置することが好ましい。上下方向に等間隔に配置された圧搾部Ｅによって、吸収性コア１１Ａに上下方向に均等な剛性を付与することができるため、吸収性コア１１Ａが偏った変形してしまう恐れを軽減させやすくなる。   Further, as shown in FIG. 2 and the like, it is preferable to arrange the plurality of squeezed portions E at equal intervals in the vertical direction. Since the absorbent cores 11A can be provided with uniform rigidity in the vertical direction by the compressed portions E arranged at equal intervals in the vertical direction, it is easy to reduce the possibility that the absorbent core 11A is deformed unevenly. .

圧搾部Ｅの左右方向の中央を吸収性コア１１Ａの左右方向の中央で、且つ吸収性本体１０の左右方向の中央に設けることで、着用者の動きに対して、吸収性コア１１Ａが左右方向について偏った変形をしてしまう恐れを軽減することができる。   By providing the center of the compressed part E in the left-right direction at the center of the absorbent core 11A in the left-right direction and at the center of the absorbent main body 10 in the left-right direction, the absorbent core 11A is moved in the left-right direction with respect to the movement of the wearer. Can be reduced.

重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅの、左右方向の長さＷｅの和（ΣＷｅ）が、上下方向の長さＤｅの和（ΣＤｅ）よりも大きい（ΣＷｅ＞ΣＤｅ）。つまり、図５に示すように、複数の圧搾部Ｅは、前側コア部１１Ａｆには、長手方向に沿って圧搾部Ｅ１、Ｅ２、Ｅ３が腹側から順に配置されている。このとき、重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅ（Ｅ１、Ｅ２、Ｅ３）の左右方向の長さＷｅの和（Ｗｅ１＋Ｗｅ２＋Ｗｅ３）が、全ての圧搾部Ｅ（Ｅ１、Ｅ２、Ｅ３）の上下方向の長さ（Ｄｅ１＋Ｄｅ２＋Ｄｅ３）よりも大きいことが好ましい。これによって、重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅの、左右方向の長さの和（ΣＷｅ）が、上下方向の長さの和（ΣＤｅ）よりも小さい場合よりも、吸収性コア１１Ａの左右方向の剛性を高くすることができ、吸収性コア１１Ａを平面形状に維持しやすくなる。背側胴回り部３０の重なり領域１１Ｐｂに設けられた圧搾部Ｅ４、Ｅ５、Ｅ６についても同様である。   The sum (ΣWe) of the lengths We in the left-right direction of all the squeezed portions E provided in the overlap region 11Pf is larger than the sum (ΣDe) of the lengths De in the vertical direction (ΣWe> ΣDe). That is, as shown in FIG. 5, in the plurality of squeezed portions E, squeezed portions E1, E2, and E3 are arranged in the front core portion 11Af along the longitudinal direction from the ventral side. At this time, the sum (We1 + We2 + We3) of the lateral lengths We of all the pressed parts E (E1, E2, E3) provided in the overlapping area 11Pf is equal to the upper and lower parts of all the pressed parts E (E1, E2, E3). It is preferable that the length is larger than the length in the direction (De1 + De2 + De3). Thereby, the absorbent core 11A is smaller than the sum of the lengths in the left-right direction (ΣWe) of all the pressed portions E provided in the overlapping region 11Pf is smaller than the sum of the lengths in the up-down direction (ΣDe). Of the absorbent core 11A can be increased, and the absorbent core 11A can be easily maintained in a planar shape. The same applies to the compressed parts E4, E5, E6 provided in the overlapping area 11Pb of the back waist part 30.

なお、圧搾部Ｅは湾曲した形状であったり、１つ以上の角を有する形状であったりするなど所望の形状でもよい。ただし、所望の形状であっても、全ての圧搾部Ｅの、左右方向の長さＷｅの和（ΣＷｅ）が、上下方向の長さＤｅの和（ΣＤｅ）よりも大きい（ΣＷｅ＞ΣＤｅ）ことが好ましい。全ての圧搾部Ｅの、左右方向の長さの和（ΣＷｅ）が、上下方向の長さの和（ΣＤｅ）よりも小さい場合よりも、吸収性コア１１Ａの左右方向の剛性を高くすることができるためである。   The pressing portion E may have a desired shape, such as a curved shape or a shape having one or more corners. However, even if it has a desired shape, the sum (ΣWe) of the lengths We in the left-right direction of all the pressed portions E is larger than the sum (ΣDe) of the lengths De in the up-down direction (ΣWe> ΣDe). Is preferred. The rigidity of the absorbent core 11A in the left-right direction can be made higher than the sum of the lengths in the left-right direction (ΣWe) of all the pressed parts E is smaller than the sum of the lengths in the up-down direction (ΣDe). This is because it can be done.

圧搾部Ｅは、左右方向に沿った直線形状であることがより好ましい。剛性を高くした領域が左右方向に沿った直線となるため、吸収性コア１１Ａの左右方向の剛性を増しやすくなり、***物を貯留する空間を確保しやすくなる。   More preferably, the pressing portion E has a linear shape along the left-right direction. Since the region having increased rigidity is a straight line along the left-right direction, the rigidity of the absorbent core 11A in the left-right direction can be easily increased, and a space for storing excrement can be easily secured.

上下方向においては、圧搾部Ｅの寸法（Ｄｅ）より、隣接する圧搾部Ｅ同士の間隔の寸法Ｄｕの方が長い（Ｄｅ＜Ｄｕ）。つまり、圧搾部Ｅの上下方向の長さ（Ｄｅ）より、上下方向に隣接する圧搾部Ｅの間隔（Ｄｕ）の方が長いため、上下方向においては、圧搾部Ｅの剛性が高い領域よりも、非圧搾部Ｕの剛性が低い領域の方が長い。そのため、圧搾部Ｅによって吸収性コア１１Ａが硬くなりすぎる恐れを軽減させることができ、着用者が感じる肌触りを向上させることができる。   In the vertical direction, the dimension Du of the interval between the adjacent compressed parts E is longer than the dimension (De) of the compressed parts E (De <Du). That is, since the interval (Du) between the vertically adjacent squeezed portions E is longer than the vertical length (De) of the squeezed portions E, the squeezed portions E in the up and down direction are more rigid than the region where the squeezed portions E have high rigidity. The region where the rigidity of the non-compressed portion U is low is longer. Therefore, the fear that the absorbent core 11A becomes too hard by the compressed portion E can be reduced, and the feel felt by the wearer can be improved.

さらに、前側幅狭部１１ｆｎに設けられている圧搾部Ｅの左右方向の長さ（Ｗｅ）が、最狭部１１ｎの左右方向の長さ（Ｗｎ）以上であることがより好ましい。前側幅狭部１１ｆｎ、最狭部１１ｎを有する吸収性コア１１Ａは、前側幅狭部１１ｆｎ等を有さない吸収性コアよりも左右方向の剛性が低くなってしまう。そのため、左右方向の剛性が最も低い最狭部１１ｎの左右方向の長さ以上の長さを有する圧搾部Ｅを設けることで、圧搾部Ｅの左右方向の長さが最狭部１１ｎの左右方向の長さより短い場合よりも吸収性コア１１Ａの左右方向の剛性を高くすることができる。なお、圧搾部Ｅの左右方向の長さ（Ｗｅ）を長くすればするほど、吸収性コア１１Ａの左右方向の剛性は高くなる。   Furthermore, the length (We) in the left-right direction of the compressed portion E provided in the front narrow portion 11fn is more preferably equal to or more than the length (Wn) in the left-right direction of the narrowest portion 11n. The absorbent core 11A having the front narrow portion 11fn and the narrowest portion 11n has lower rigidity in the left-right direction than the absorbent core having no front narrow portion 11fn and the like. Therefore, by providing the compressed part E having a length equal to or longer than the length in the left-right direction of the narrowest part 11n having the lowest rigidity in the left-right direction, the length of the compressed part E in the left-right direction is smaller than that of the narrowest part 11n. The rigidity of the absorbent core 11A in the left-right direction can be made higher than when the length is shorter than the length. In addition, the rigidity of the absorbent core 11A in the left-right direction increases as the length (We) of the compressed portion E in the left-right direction increases.

前側コア部１１Ａｆの重なり領域１１Ｐｆ又は後側コア部１１Ａｂの重なり領域１１Ｐｂにおいて、圧搾部Ｅの左右方向の端が、前側コア部１１Ａｆ又は後側コア部１１Ａｂの左右方向の端に接していないことがより好ましい。つまり、図５において、重なり領域１１Ｐｆ、１１Ｐｂにおいて、圧搾部Ｅの左右方向の各端と、前側コア部１１Ａｆ、後側コア部１１Ａｂの左右方向の端との間に非圧搾部Ｕを有している。重なり領域１１Ｐｆ、重なり領域１１Ｐｂは、腹部や背部に近い領域であるため、圧搾部Ｅを広く形成すると、着用者は吸収性コア１１Ａの硬さを感じてしまう恐れがある。そのため、着用者の腹部やそけい部、背部や臀部の動きを制限し、吸収性コア１１Ａが過度に硬くなるのを防ぐことができる。   In the overlapping region 11Pf of the front core portion 11Af or the overlapping region 11Pb of the rear core portion 11Ab, the left-right end of the compressed portion E does not contact the left-right end of the front core portion 11Af or the rear core portion 11Ab. Is more preferred. That is, in FIG. 5, in the overlapping regions 11Pf and 11Pb, the non-pressed portions U are provided between the left and right ends of the pressed portion E and the left and right ends of the front core portion 11Af and the rear core portion 11Ab. ing. Since the overlap region 11Pf and the overlap region 11Pb are regions close to the abdomen and the back, if the compressed portion E is formed wide, the wearer may feel the hardness of the absorbent core 11A. Therefore, the movement of the wearer's abdomen, groin, back, and buttocks can be restricted, and the absorbent core 11A can be prevented from being excessively hard.

図２等に示すように、前側コア部１１Ａｆの、腹側胴回り部２０の下端よりも上側に、上部１１ｆｕよりも左右方向の長さが短い幅狭部１１ｆｎを設けることで、脚を前に出した姿勢の乳幼児の脚の動きを阻害する恐れを軽減させている。このとき、腹側胴回り部２０の下端よりも上側の幅狭部１１ｆｎに１つ以上の圧搾部Ｅを設けることが好ましい。つまり、前側コア部１１Ａｆの重なり領域１１Ｐｆであり、且つ幅狭部１１ｆｎに、１つ以上の圧搾部Ｅを設けることが好ましい。乳幼児が左右方向に脚を閉じると、吸収性コア１１Ａのうち、幅狭部１１ｆｎにおける左右方向の端に左右方向からの力が集中しやすくなる。そのため、幅狭部１１ｆｎは特に左右方向から潰される変形を生じやすい。これを防ぐために、左右方向からの力が集中しやすい重なり領域１１Ｐｆであり、且つ幅狭部１１ｆｎに圧搾部Ｅを設けて左右方向の剛性を高めて、吸収性コア１１Ａの変形を軽減させることが好ましい。   As shown in FIG. 2 and the like, the front core portion 11Af is provided above the lower end of the abdominal waistline portion 20 with a narrow portion 11fn having a shorter length in the left-right direction than the upper portion 11fu. This reduces the risk of obstructing the movement of the legs of the infant in the outgoing posture. At this time, it is preferable to provide one or more compressed portions E in the narrow portion 11fn above the lower end of the abdominal waist portion 20. That is, it is preferable to provide one or more squeezed portions E in the overlap region 11Pf of the front core portion 11Af and in the narrow portion 11fn. When the infant closes the leg in the left-right direction, the force from the left-right direction tends to concentrate on the left-right end of the narrow portion 11fn of the absorbent core 11A. For this reason, the narrow portion 11fn is liable to be deformed particularly in the left and right directions. In order to prevent this, the overlapping region 11Pf in which the force from the left and right directions is likely to be concentrated, and the compressed portion E is provided in the narrow portion 11fn to increase the rigidity in the left and right directions to reduce the deformation of the absorbent core 11A. Is preferred.

また、図８に示すように、圧搾部Ｅが、前後方向において非伸縮領域Ｆｆや非伸縮領域Ｆｂと重なる位置に設けられていることが好ましい。このようにすることで、圧搾部Ｅが重なり領域１１Ｐｆ及び重なり領域１１Ｐｂの左右方向の剛性を高くするため、乳幼児の動きによって変形しやすい非伸縮領域Ｆｆ及び非伸縮領域Ｆｂを平面形状に保ちやすくすることができ、吸収性本体１０が乳幼児の身体から離れてしまう恐れを軽減することができる。   In addition, as shown in FIG. 8, it is preferable that the pressing portion E is provided at a position overlapping the non-stretchable region Ff and the non-stretchable region Fb in the front-rear direction. In this way, since the squeezed portion E increases the rigidity of the overlapping region 11Pf and the overlapping region 11Pb in the left-right direction, the non-stretchable region Ff and the non-stretchable region Fb, which are easily deformed by the movement of the baby, can be easily maintained in a planar shape. It is possible to reduce the risk that the absorbent main body 10 separates from the body of the infant.

さらに、前側コア部１１Ａｆ又は後側コア部１１Ａｂの圧搾部Ｅの左右方向の両端が、非伸縮領域Ｆｆ又は非伸縮領域Ｆｂよりもそれぞれ外側に設けられていることが好ましい。図２に示すように、おむつ１は、前側コア部１１Ａｆの圧搾部Ｅの左右方向の両端が、非伸縮領域Ｆｆよりもそれぞれ外側に設けられている。非伸縮領域Ｆｆは、乳幼児の脚の動きによって吸収性本体１０が着用者の肌から離れて浮きやすい。そのため、非伸縮領域Ｆｆよりも左右方向に長い領域に亘って吸収性コア１１Ａの剛性を高めることで、吸収性本体１０が肌に接する状態を保ちやすくなる。また、圧搾部Ｅの左右方向の両端がそれぞれ伸縮領域Ｄｆ内に設けられていることで、伸縮領域Ｄｆが圧搾部Ｅの各両端に左右方向に伸長させる力を加えるため、非伸縮領域Ｆｆと前後方向で重なる吸収性本体１０の部分についても着用者の肌に接した状態を維持しやすく、身体にフィットした状態にさせやすい。   Further, it is preferable that both left and right ends of the compressed portion E of the front core portion 11Af or the rear core portion 11Ab are provided outside the non-stretchable region Ff or the non-stretchable region Fb, respectively. As shown in FIG. 2, in the diaper 1, both ends in the left-right direction of the compressed portion E of the front core portion 11Af are provided outside the non-stretchable region Ff. In the non-stretchable region Ff, the absorbent body 10 is easily lifted away from the wearer's skin by the movement of the infant's leg. Therefore, by increasing the rigidity of the absorbent core 11A over a region longer in the left-right direction than the non-stretchable region Ff, it becomes easier to keep the absorbent main body 10 in contact with the skin. In addition, since the left and right ends of the compressed portion E are provided in the stretchable region Df, the stretchable region Df applies a force to expand both sides of the compressed portion E in the left and right direction. The portion of the absorbent main body 10 that overlaps in the front-rear direction can be easily maintained in contact with the wearer's skin, and can be easily fitted to the body.

図２の前側コア部１１Ａｆのように、糸ゴム２３ａと前後方向において重なっている圧搾部Ｅを有することが好ましい。圧搾部Ｅと前後方向において重なっている糸ゴム２３ａが伸縮すると、糸ゴム２３ａと前後方向において重なっている圧搾部Ｅは、左右方向に伸長させる力が加えられるため、圧搾部Ｅは平面形状を維持しやすくなり、吸収性本体１０が乳幼児の身体から離れてしまう恐れを軽減させることができる。なお、後側コア部１１Ａｂについても同様の構成にしてもよい。   It is preferable to have a pressing part E that overlaps the thread rubber 23a in the front-rear direction like the front core part 11Af in FIG. When the thread rubber 23a overlapping in the front-rear direction with the pressing part E expands and contracts, the pressing part E overlapping in the front-rear direction with the thread rubber 23a is applied with a force to expand in the left-right direction. It becomes easy to maintain, and the possibility that the absorbent main body 10 separates from the body of the infant can be reduced. The rear core 11Ab may have the same configuration.

また、前側コア部１１Ａｆ又は後側コア部１１Ａｂの圧搾部Ｅの左右方向の両端が、非伸縮領域Ｆｆ又は非伸縮領域Ｆｂよりもそれぞれ内側に設けられていてもよい。図２に示すように、おむつ１は、後側コア部１１Ａｆの圧搾部Ｅの左右方向の両端が、非伸縮領域Ｆｂよりもそれぞれ内側に設けられている。吸収性コア１１Ａと後側胴回り伸縮部材３３とが前後方向において重なった領域は、後側胴回り伸縮部材３３が収縮すると硬くなりやすい部分である。その硬くなりやすい部分に圧搾部Ｅを設けると、より硬さを増長させてしまい、乳幼児が感じる肌触りを低下させてしまう恐れがある。そのため、後側コア部１１Ａｆの圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｂの両端よりもそれぞれ内側に設けることで、着用時の肌触りを向上させることができる。つまり、吸収性本体１０を身体にフィットさせることよりも、吸収性本体１０の肌触りを向上させたい場合には、前側コア部１１Ａｆ又は後側コア部１１Ａｂの圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｆ又は非伸縮領域Ｆｂよりもそれぞれ内側に設けるとよい。   The left and right ends of the compressed portion E of the front core portion 11Af or the rear core portion 11Ab may be provided inside the non-stretchable region Ff or the non-stretchable region Fb, respectively. As shown in FIG. 2, in the diaper 1, both ends in the left-right direction of the compressed portion E of the rear core portion 11Af are provided inside the non-stretchable region Fb. The region where the absorbent core 11A and the rear waist elastic member 33 overlap in the front-rear direction is a portion that tends to become hard when the rear waist elastic member 33 contracts. If the compressed portion E is provided in a portion that is likely to be hard, the hardness is further increased, and there is a fear that the feel felt by infants may be reduced. Therefore, by providing the left and right ends of the compressed portion E of the rear core portion 11Af inside the both ends of the non-stretchable region Fb, it is possible to improve the feel when worn. That is, when it is desired to improve the feel of the absorbent main body 10 rather than fitting the absorbent main body 10 to the body, the left and right ends of the compressed portion E of the front core portion 11Af or the rear core portion 11Ab are It is good to provide in each non-stretchable area Ff or non-stretchable area Fb inside.

おむつ１のように、前側コア部１１Ａｆの圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｆよりもそれぞれ外側に設け、後側コア部１１Ａｆの圧搾部Ｅの左右方向の両端が、非伸縮領域Ｆｂよりもそれぞれ内側に設けることがより好ましい。乳幼児の脚によって吸収性コアが変形しやすい前側コア部１１Ａｆの左右方向の剛性をより高くすることで、前側コア部１１Ａｆの変形を軽減させつつ、変形が比較的少ない後側コア部１１Ａｂについては、左右方向の剛性をより低くして、吸収性コア１１Ａの肌触りを向上させて、吸収性コア１１Ａを乳幼児の身体に沿いやすくさせることができる。   Like the diaper 1, the left and right ends of the pressed portion E of the front core portion 11Af are provided outside the non-stretchable region Ff, respectively, and the left and right ends of the pressed portion E of the rear core portion 11Af are non-stretched. It is more preferable to provide each of them inside the region Fb. By increasing the rigidity in the left-right direction of the front core portion 11Af in which the absorbent core is likely to be deformed by the infant's leg, the deformation of the front core portion 11Af is reduced, and the rear core portion 11Ab with relatively little deformation is reduced. Further, the rigidity in the left-right direction can be further reduced, the feel of the absorbent core 11A can be improved, and the absorbent core 11A can be easily fitted to the body of the baby.

図２等に示すように、圧搾部ＥとスリットＳが、上下方向において重なっていることが好ましい。スリットＳは、吸収性コア１１Ａを乳幼児のお尻の形状に沿いやすくさせるために設けているが、乳幼児の動きによってスリットＳを起点に吸収性コア１１Ａが変形してしまう恐れがある。そのため、スリットＳと上下方向に重なる位置に圧搾部Ｅを設けることで、スリットＳを形成した領域も含めて吸収性コア１１Ａを平面形状に保ちやすくすることができる。   As shown in FIG. 2 and the like, it is preferable that the pressing portion E and the slit S overlap in the vertical direction. The slit S is provided to make the absorbent core 11A easily conform to the shape of the buttocks of the infant, but there is a possibility that the absorbent core 11A may be deformed from the slit S by the movement of the infant. Therefore, by providing the compressed portion E at a position overlapping the slit S in the vertical direction, the absorbent core 11A including the region where the slit S is formed can be easily maintained in a planar shape.

＝＝＝その他の実施の形態＝＝＝
以上、本発明の実施形態について説明したが、上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。例えば、以下に示すような変形が可能である。 === Other Embodiments ===
As described above, the embodiments of the present invention have been described. However, the above embodiments are for facilitating the understanding of the present invention, and are not for limiting and interpreting the present invention. Further, the present invention can be changed or improved without departing from the gist thereof, and it goes without saying that the present invention includes equivalents thereof. For example, the following modifications are possible.

上述の実施形態においては、左右方向に沿った直線状の圧搾部Ｅを設けたが、圧搾部の形状はこれに限られない。左右方向に所定の長さを有する圧搾部Ｅであれば、波型等の所望の形状とすることができる。図９は、別の実施形態にかかる吸収体１１を説明する図である。図９においては、吸収性コア１１Ａ等は、コアラップシート１１Ｂに覆われているが、便宜上実線で示している。図９に示すように、腹側に凸形状を有する山型の圧搾部Ｅであってもよい。圧搾部Ｅは、左右方向の一方側から他方側まで連続した連続圧搾形状を有している。圧搾部Ｅの上端のうち、左右方向において、最も下側に位置する部位Ｅｊから最も上側に位置する部位Ｅｋをつなぐ直線と、左右方向に沿った直線とがなす角度のうち、小さい方の角度θｅが４５度よりも小さいことが好ましい（θｅ＜４５°）。これによって、θｅが４５度以上であった場合よりも、圧搾部Ｅによって吸収性コア１１Ａの剛性を高くすることができるため、吸収性コア１１Ａを平面形状で維持しやすくなる。   In the above-described embodiment, the linear compressed portion E is provided along the left-right direction, but the shape of the compressed portion is not limited to this. As long as the pressed portion E has a predetermined length in the left-right direction, it can be formed into a desired shape such as a corrugated shape. FIG. 9 is a diagram illustrating an absorber 11 according to another embodiment. In FIG. 9, the absorbent core 11A and the like are covered with the core wrap sheet 11B, but are indicated by solid lines for convenience. As shown in FIG. 9, a mountain-shaped pressing portion E having a convex shape on the abdominal side may be used. The pressing portion E has a continuous pressing shape that is continuous from one side in the left-right direction to the other side. Among the upper ends of the squeezed portions E, in the left-right direction, the smaller angle of the angle formed by the straight line connecting the lowermost part Ej to the uppermost part Ek and the straight line along the left-right direction It is preferable that θe is smaller than 45 degrees (θe <45 °). Thereby, the rigidity of the absorbent core 11A can be increased by the compressed portion E as compared with the case where θe is 45 degrees or more, so that the absorbent core 11A can be easily maintained in a planar shape.

この場合においても、重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅの、左右方向の長さＷｅの和（ΣＷｅ）が、上下方向の長さＤｅの和（ΣＤｅ）よりも大きい（ΣＷｅ＞ΣＤｅ）。つまり、図９に示すように、重なり領域１１Ｐｆに設けられた複数の圧搾部Ｅは、長手方向に沿って圧搾部Ｅ２１、Ｅ２２、Ｅ２３が腹側から順に配置されている。このとき、重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅ（Ｅ２１、Ｅ２２、Ｅ２３）の左右方向の長さＷｅの和（Ｗｅ２１＋Ｗｅ２２＋Ｗｅ２３）が、重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅ（Ｅ２１、Ｅ２２、Ｅ２３）の上下方向の長さ（Ｄｅ２１＋Ｄｅ２２＋Ｄｅ２３）よりも大きいことが好ましい。これによって、重なり領域１１Ｐｆに設けられた全ての圧搾部Ｅの、左右方向の長さの和（ΣＷｅ）が、上下方向の長さの和（ΣＤｅ）よりも小さい場合よりも、吸収性コア１１Ａの左右方向の剛性を高くすることができる。前側コア部１１Ａｆの重なり領域１１Ｐｆに設けられた圧搾部Ｅについて説明したが、後側コア部１１Ａｂの重なり領域Ｐｂに設けられた圧搾部Ｅについても同様である。   Also in this case, the sum (ΣWe) of the lengths We in the left-right direction of all the squeezed portions E provided in the overlap region 11Pf is larger than the sum (ΣDe) of the lengths De in the vertical direction (ΣWe> ΣDe). ). That is, as shown in FIG. 9, in the plurality of compressed portions E provided in the overlap region 11Pf, the compressed portions E21, E22, and E23 are sequentially arranged from the ventral side along the longitudinal direction. At this time, the sum (We21 + We22 + We23) of the horizontal lengths We of all the compressed parts E (E21, E22, E23) provided in the overlapping area 11Pf is equal to all the compressed parts E (E21) provided in the overlapping area 11Pf. , E22, E23) is preferably larger than the vertical length (De21 + De22 + De23). Thereby, the absorbent core 11A is smaller than the sum of the lengths in the left-right direction (ΣWe) of all the pressed portions E provided in the overlapping region 11Pf is smaller than the sum of the lengths in the up-down direction (ΣDe). Stiffness in the left-right direction can be increased. Although the compressed portion E provided in the overlapping region 11Pf of the front core portion 11Af has been described, the same applies to the compressed portion E provided in the overlapping region Pb of the rear core portion 11Ab.

また、吸収性コア１１Ａに施す圧搾部Ｅの左右方向の長さ及び上下方向の長さは、必ずしも全て同じでなくてもよい。おむつ１の圧搾部Ｅは、全ての圧搾部Ｅの左右方向の長さ及び上下方向の長さを同じとしたが、それぞれ異なる長さとすることもできる。   Further, the length in the left-right direction and the length in the up-down direction of the compressed portion E applied to the absorbent core 11A are not necessarily all the same. The pressed portions E of the diaper 1 have the same length in the left-right direction and the length in the up-down direction of all the pressed portions E, but may have different lengths.

例えば、図１０に示すように、重なり領域１１Ｐｆに設けられた複数の圧搾部Ｅの左右方向の長さはそれぞれ異なっていてもよい。図１０は、別の実施形態にかかる圧搾部Ｅと、伸縮領域Ｄｆ、Ｄｂ及び非伸縮領域Ｆｆ、Ｆｂについて説明する図である。具体的には、最も上側に位置し、左右方向の長さが最も短い短圧搾部Ｅｓと、最も下側に位置し、左右方向の長さが最も長い長圧搾部Ｅｔを有している。短圧搾部Ｅｓの左右方向の両端は、非伸縮領域Ｆｆの左右方向の両端よりもそれぞれ内側に設けられており、長圧搾部Ｅｔの左右方向の両端は、非伸縮領域Ｆｆの左右方向の両端よりもそれぞれ外側に設けられている。つまり、短圧搾部Ｅｓの左右方向の長さは非伸縮領域Ｆｆの左右方向の長さよりも長く、長圧搾部Ｅｔの左右方向の長さは非伸縮領域Ｆｆの左右方向の長さよりも短い。このようにすることで、重なり領域１１Ｐｆのうち、乳幼児の脚の動きに応じて吸収性本体１０が非肌側に浮きやすい下側の領域には、圧搾部Ｅの左右方向の長さを長くして左右方向の剛性をより高めている。一方、重なり領域１１Ｐｆのうち、乳幼児の脚から遠い領域で、吸収性本体１０の動きが小さい上側の領域には、圧搾部Ｅの左右方向の長さを短くして、吸収性コア１１Ａが過度に硬くなって、肌触りが低下してしまう恐れを軽減させることができる。   For example, as shown in FIG. 10, the lengths in the left-right direction of the plurality of squeezed portions E provided in the overlap region 11Pf may be different from each other. FIG. 10 is a diagram illustrating a compressed portion E according to another embodiment, and stretchable regions Df and Db and non-stretchable regions Ff and Fb. Specifically, it has a short compression part Es located at the uppermost position and having the shortest length in the left-right direction, and a long compression part Et located at the lowest position and having the longest length in the left-right direction. The left and right ends of the short compressed portion Es are provided inside the left and right ends of the non-stretchable region Ff, respectively, and the left and right ends of the long compressed portion Et are left and right ends of the non-stretchable region Ff. Respectively, are provided outside. That is, the length of the short compressed portion Es in the left-right direction is longer than the length of the non-stretchable region Ff in the left-right direction, and the length of the long compressed portion Et in the left-right direction is shorter than the length of the non-stretchable region Ff in the left-right direction. In this way, in the overlapping area 11Pf, in the lower area where the absorbent main body 10 is likely to float on the non-skin side in response to the movement of the infant's leg, the length of the compressed portion E in the left-right direction is increased. To increase the rigidity in the left-right direction. On the other hand, in the overlapping region 11Pf, in the region far from the infant's leg and in the upper region where the movement of the absorbent main body 10 is small, the length in the left-right direction of the squeezing portion E is shortened so that the absorbent core 11A To reduce the possibility that the skin feels soft.

また、上述の実施形態においては、前側コア部１１Ａｆの重なり領域１１Ｐｆに設けた圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｆの両端よりも外側に設け、後側コア部１１Ａｂの重なり領域１１Ｐｂに設けた圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｂの両端よりも内側に設けたが、これに限られない。例えば、腹側及び背側において吸収性本体１０の変形をより防止したい場合には、全ての圧搾部Ｅの両端を非伸縮領域Ｆｆ、Ｆｂの両端よりも外側に設けてもよい。腹側及び背側の肌触りをより向上させたい場合には、全ての圧搾部Ｅの両端を非伸縮領域Ｆｆ、Ｆｂの両端よりも内側に設けてもよい。また、前側コア部１１Ａｆの重なり領域１１Ｐｆに設けた圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｆの両端よりも内側に設け、後側コア部１１Ａｂの重なり領域１１Ｐｂに設けた圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｂの両端よりも外側に設けてもよい。このようにすることで、腹側においては、乳幼児の身体は腹部が前にせり出しているため、腹側胴回り伸縮部材２３の収縮によって縮められた吸収性コア１１Ａと圧搾部Ｅが重なってしまって吸収性本体１０が硬くなってしまい肌触りが低下してしまう恐れを軽減することができる。一方、背側においては、より左右方向に長い圧搾部を設けることで吸収性コア１１Ａを左右方向に平面形状に維持しやすくすることができるため、吸収性コアを肌に密着させやすくすることができる。   Further, in the above-described embodiment, the left and right ends of the compressed portion E provided in the overlapping region 11Pf of the front core portion 11Af are provided outside the both ends of the non-stretchable region Ff, and the overlapping region of the rear core portion 11Ab is provided. The left and right ends of the compressed portion E provided on 11Pb are provided inside the both ends of the non-stretchable region Fb, but the present invention is not limited to this. For example, when it is desired to further prevent the deformation of the absorbent main body 10 on the abdominal side and the back side, both ends of all the compressed portions E may be provided outside the both ends of the non-stretchable regions Ff and Fb. When it is desired to further improve the touch on the abdominal side and the back side, both ends of all the pressed parts E may be provided inside both ends of the non-stretchable regions Ff and Fb. Also, the left and right ends of the compressed portion E provided in the overlapping region 11Pf of the front core portion 11Af are provided inside both ends of the non-stretchable region Ff, and the compressed portions E provided in the overlapping region 11Pb of the rear core portion 11Ab. May be provided outside both ends of the non-stretchable region Fb. By doing so, on the ventral side, the abdomen of the infant's body protrudes forward, so that the absorbent core 11A contracted by the contraction of the abdominal waist elastic member 23 and the compressed portion E overlap. It is possible to reduce the possibility that the absorbent main body 10 becomes hard and the touch is reduced. On the other hand, on the dorsal side, the absorbent core 11A can be easily maintained in a planar shape in the left-right direction by providing a longer pressing portion in the left-right direction, so that the absorbent core can be easily adhered to the skin. it can.

さらに、おむつ１のように、図８に示すように、前側コア部１１Ａｆの重なり領域１１Ｐｆに設けた圧搾部Ｅの左右方向の長さを重なり領域１１Ｐｂに設けた圧搾部Ｅの左右方向の長さよりも長くし、重なり領域１１Ｐｆに設けた圧搾部Ｅの両端を、非伸縮領域Ｆｆの両端よりも外側に設け、且つ、後側コア部１１Ａｂの重なり領域１１Ｐｂに設けた圧搾部Ｅの左右方向の両端を、非伸縮領域Ｆｂの両端よりも内側に設けることがより好ましい。乳幼児は、脚を前に出した姿勢でいることが多いため、脚の動きによって変形しやすい吸収性本体１０の前側コア部１１Ａｆには、左右方向の剛性をより高くして、前側コア部１１Ａを平面形状に維持しやすくする。一方、吸収性本体１０の変形がより少ない後側コア部１１Ａｂには、左右方向の剛性を高くしすぎないようにして、着用者の身体に沿いやすくさせ、肌触りを向上させる。   Further, as in the diaper 1, as shown in FIG. 8, the length in the left-right direction of the compressed portion E provided in the overlapping region 11Pf of the front core portion 11Af is the length in the left-right direction of the compressed portion E provided in the overlapping region 11Pb. , And both ends of the compressed portion E provided in the overlapping region 11Pf are provided outside the both ends of the non-stretchable region Ff, and the lateral direction of the compressed portion E provided in the overlapping region 11Pb of the rear core portion 11Ab. Are more preferably provided inside both ends of the non-stretchable region Fb. Since the infant is often in a posture in which the leg is put forward, the rigidity in the left-right direction is increased in the front core portion 11Af of the absorbent main body 10 which is easily deformed by the movement of the leg, and the front core portion 11A In a planar shape. On the other hand, in the rear core portion 11Ab in which the deformation of the absorbent main body 10 is smaller, the rigidity in the left-right direction is not made too high, so that the rear core portion 11Ab can easily follow the wearer's body and improve the touch.

上述の実施形態においては、腹側胴回り部２０及び背側胴回り部３０は、それぞれ非伸縮領域Ｆｆ、Ｆｂを備えていたが、必ずしも非伸縮領域Ｆｆ、Ｆｂを必ずしも備えていなくてもよい。腹側胴回り部２０及び背側胴回り部３０が非伸縮領域Ｆｆ、Ｆｂを備えない場合には、吸収性本体１０は、腹側胴回り伸縮部材２３及び背側胴回り伸縮部材３３の伸縮力と、吸収性コア１１Ａに設けられた圧搾部Ｅによって、乳幼児の身体により密着させやすくすることができる。   In the above-described embodiment, the abdominal waistline portion 20 and the back waistline portion 30 have the non-stretchable regions Ff and Fb, respectively. However, the abdominal waistline portion 20 and the dorsal waistline portion 30 need not necessarily have the non-stretchable regions Ff and Fb. When the abdominal waistline portion 20 and the back waistline portion 30 do not include the non-stretchable regions Ff and Fb, the absorbent body 10 absorbs the elasticity of the abdominal waistline elastic member 23 and the back waistline elastic member 33 and absorbs them. The compressed part E provided on the sex core 11A can make it easier to adhere to the body of the baby.

上述の実施形態においては、圧搾部Ｅを上下方向において等間隔に配置したが、これに限られない。圧搾部Ｅを不等間隔に配置してもよい。例えば、図１２は、別の実施形態にかかる展開状態且つ伸長状態のおむつ１を肌側から見た概略平面図である。図１２に示すように、重なり領域１１Ｐｆに設けた複数の圧搾部Ｅｙ、Ｅｚのうち、最も下側に位置する胴回り下側圧搾部Ｅｙと、胴回り下側圧搾部Ｅｙに上側から隣接する隣接胴回り下側圧搾部Ｅｚとの間隔Ｄｙｚは、非重なり領域１１Ｑｆに設けた複数の圧搾部Ｅａ、Ｅｂ、Ｅｃ、Ｅｄのうち、最も下側に位置する下側圧搾部Ｅａと、下側圧搾部Ｅａに上側から隣接する隣接下側圧搾部Ｅｂとの間隔Ｄａｂよりも大きくてもよい（Ｄｙｚ＞Ｄａｂ）。さらに、非重なり領域１１Ｑｆに設けた複数の圧搾部Ｅａ、Ｅｂ、Ｅｃ、Ｅｄのうち、最も上側に位置する上側圧搾部Ｅｃと、上側圧搾部Ｅｃに下側から隣接する隣接上側圧搾部Ｅｄとの間隔Ｄｃｄよりも、最も下側に位置する下側圧搾部Ｅａと、下側圧搾部Ｅａに上側から隣接する隣接下側圧搾部Ｅｂとの間隔Ｄａｂは小さい（Ｄａｂ＜Ｄｃｄ）。   In the above-described embodiment, the squeezing portions E are arranged at equal intervals in the up-down direction, but are not limited thereto. The pressing parts E may be arranged at irregular intervals. For example, FIG. 12 is a schematic plan view of the diaper 1 according to another embodiment in an unfolded state and an expanded state, as viewed from the skin side. As shown in FIG. 12, among the plurality of compressed portions Ey and Ez provided in the overlapping region 11Pf, the lower waistline pressed portion Ey located at the lowermost side and the adjacent waistline adjacent to the lower waistline pressed portion Ey from above. The interval Dyz between the lower pressing portion Ez and the lower pressing portion Ea, the lower pressing portion Ea located at the lowest position among the plurality of pressing portions Ea, Eb, Ec, Ed provided in the non-overlapping area 11Qf. May be larger than the distance Dab between the adjacent lower pressing portion Eb adjacent from the upper side (Dyz> Dab). Furthermore, of the plurality of compressed parts Ea, Eb, Ec, Ed provided in the non-overlap area 11Qf, the uppermost compressed part Ec located at the uppermost position, and the adjacent upper compressed part Ed adjacent to the upper compressed part Ec from below. Is smaller (Dab <Dcd) between the lower compressed portion Ea located at the lowermost side and the adjacent lower compressed portion Eb adjacent to the lower compressed portion Ea from above.

このようにすることで、吸収性コア１１Ａの変形がより起こりやすい非重なり領域１１Ｑｆには、より多くの圧搾部Ｅを設けることで剛性をより向上させて、吸収性コア１１Ａの平面形状を維持しやすくすることができる。吸収性コア１１Ａの変形がより少ない重なり領域１１Ｐｆには、圧搾部Ｅをより少なく設けることで吸収性本体１０の肌触りをより向上させることができる。また、非重なり領域１１Ｑｆのうち、より脚回り開口部ＬＨに近い下側の領域には、より多くの圧搾部Ｅを設けて、吸収性本体１１Ａの左右方向の剛性を高めて、吸収性コア１１Ａの変形を軽減することができる。一方、より脚回り開口部ＬＨから遠い上側の領域には、より少ない圧搾部Ｅとすることで、吸収性本体１１Ａを過度に硬くしてしまうことを軽減して、吸収性本体１０の肌触りを向上させることができる。   By doing so, in the non-overlapping area 11Qf where the deformation of the absorbent core 11A is more likely to occur, the rigidity is further improved by providing more compressed parts E, and the planar shape of the absorbent core 11A is maintained. Can be made easier. In the overlapping region 11Pf where the deformation of the absorbent core 11A is less, the touch of the absorbent main body 10 can be further improved by providing the compressed portion E less. Further, in the non-overlapping area 11Qf, in the lower area closer to the leg opening LH, more squeezed portions E are provided to increase the rigidity of the absorbent main body 11A in the left-right direction, thereby increasing the absorbent core. 11A can be reduced. On the other hand, in the region on the upper side farther from the leg opening LH, it is possible to reduce the excessively hardening of the absorbent main body 11A by making the compressed part E smaller to reduce the touch of the absorbent main body 10. Can be improved.

上述の実施形態においては、吸収性コア１１Ａに、全て同じ溝の深さの圧搾部Ｅを複数形成したが、これに限られない。吸収性コア１１Ａ内において、異なる深さの圧搾部Ｅを形成してもよい。例えば、前側コア部１１Ａｆのうち、より左右方向の剛性を高くしたい前側コア部Ａの下側の領域には、より深い溝の圧搾部Ｅを形成し、腹側胴回り部２０に近い部分には、より浅い溝の圧搾部Ｅを形成してもよい。   In the above-described embodiment, a plurality of squeezed portions E all having the same groove depth are formed in the absorbent core 11A, but the invention is not limited thereto. Pressed portions E having different depths may be formed in the absorbent core 11A. For example, in the front core portion 11Af, in a region below the front core portion A where the rigidity in the left-right direction is desired to be increased, a compressed portion E of a deeper groove is formed, and a portion close to the abdominal waist portion 20 is formed. Alternatively, a compressed portion E of a shallower groove may be formed.

さらに、本実施形態においては、前側コア部１１Ａｆに最狭部１１ｎを備える吸収性コア１１Ａとしたがこれに限られない。例えば、吸収性コア１１Ａは、最狭部１１ｎをおむつ１の下部に備え、前側コア部１１Ａｆから後側コア部１１Ａｂに連続した領域に設けていてもよい。また、幅狭部１１ｆｎ、１１ｂｎを有さない長方形の吸収性コア１１Ａであってもよい。   Further, in the present embodiment, the absorbent core 11A has the narrowest portion 11n in the front core portion 11Af, but is not limited thereto. For example, the absorbent core 11A may include the narrowest portion 11n below the diaper 1, and may be provided in a region continuous from the front core portion 11Af to the rear core portion 11Ab. Further, a rectangular absorbent core 11A having no narrow portions 11fn and 11bn may be used.

上述の実施形態においては、パンツ型吸収性物品は、腹側胴回り部２０と背側胴回り部３０と吸収性本体１０とを有する所謂３ピースタイプの使い捨ておむつとして説明したがこれに限られない。例えば、外装シート１４が腹側胴回り部２０と後胴回り３０とを繋いで一体化されたおむつ（所謂２ピースタイプ）であってもよい。   In the above-described embodiment, the pants-type absorbent article has been described as a so-called three-piece disposable diaper having the abdominal waist portion 20, the back waist portion 30, and the absorbent body 10, but is not limited thereto. For example, the outer sheet 14 may be a diaper (a so-called two-piece type) in which the abdominal waistline portion 20 and the rear waistline 30 are connected and integrated.

上述の実施形態においては、腹側胴回り部２０、背側胴回り部３０、防漏壁部５０、及び脚回り部６０が備える伸縮部材（２２、３２、５１、１６）として糸ゴム及び伸縮不織布を例示しているがこれに限らない。例えば、糸ゴムや伸縮不織布だけでなく、伸縮性フィルム等のシート状の伸縮部材を単数又は複数配してもよい。また、図面には伸縮部材のうち伸縮性を発現する部位（所謂有効長の部位）のみを示している。そのため図示する伸縮部材の長手方向の外側に伸縮性を発現しない伸縮部材の部位が存在していてもよい。また、伸縮部材の配置や本数も図示する構成に限らない。   In the above-described embodiment, thread rubber and elastic nonwoven fabric are used as the elastic members (22, 32, 51, 16) provided in the abdominal waist portion 20, the back waist portion 30, the leak-proof wall portion 50, and the leg waist portion 60. Although illustrated, the invention is not limited to this. For example, one or more sheet-like elastic members such as elastic films may be provided in addition to the thread rubber and the elastic nonwoven fabric. Further, in the drawings, only a portion of the elastic member that exhibits elasticity (a so-called effective length portion) is shown. Therefore, a portion of the elastic member that does not exhibit elasticity may exist outside the illustrated elastic member in the longitudinal direction. Further, the arrangement and the number of the elastic members are not limited to the illustrated configuration.
