FIG. 4 is a schematic view of the absorbent article 1 in a planar state and in an elongated state.

吸収性物品１は、例えば生理用品、大人用・乳児用のおむつとして利用可能であり、図１に示すパンツ型状態において、互いに直交する縦方向と横方向と前後方向とを有する。また、吸収性物品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。縦方向において、胴回り開口部ＢＨ側を上側とし、着用者の股下に対応する側を下側とする。前後方向において、着用者の腹側に対応する側を前側とし、着用者の背側に対応する側を後側とする。また、吸収性物品１は厚さ方向を有し、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。   The absorbent article 1 can be used, for example, as a sanitary product, a diaper for adults and babies, and has a vertical direction, a horizontal direction, and a front-rear direction orthogonal to each other in the pants-type state shown in FIG. Further, the absorbent article 1 is formed with a waist opening BH and a pair of leg openings LH. In the vertical direction, the waistline opening BH side is the upper side, and the side corresponding to the wearer's crotch is the lower side. In the front-rear direction, the side corresponding to the wearer's ventral side is the front side, and the side corresponding to the wearer's back side is the rear side. Moreover, the absorbent article 1 has a thickness direction, and the side which contacts a wearer in the thickness direction is a skin side, and the opposite side is a non-skin side.

また、吸収性物品１は、パンツ型状態において、縦方向に長手方向を沿わせつつ長手方向の略中央で２つ折りされた吸収性本体１０と、吸収性本体１０の横方向の両側にそれぞれ配され、横方向に伸縮する一対のベルト部２０と、吸収性本体１０の長手方向に沿って吸収性本体１０の横方向の両側にそれぞれ配された一対のレッグギャザー部３０とを有する。以下の説明では、一対のベルト部２０のうち横方向の一方側のものを第１ベルト部２１、横方向の他方側のものを第２ベルト部２２とも呼ぶ。また、一対のレッグギャザー部３０のうち横方向の一方側のものを第１レッグギャザー部３１、横方向の他方側のものを第２レッグギャザー部３２とも呼ぶ。   Moreover, the absorbent article 1 is disposed on each side of the absorbent body 10 in the pants-type state, the absorbent body 10 being folded in half at the approximate center of the longitudinal direction along the longitudinal direction, and both sides of the absorbent body 10 in the lateral direction. And a pair of belt portions 20 extending and contracting in the lateral direction, and a pair of leg gather portions 30 disposed on both sides of the absorbent main body 10 in the lateral direction along the longitudinal direction of the absorbent main body 10. In the following description, one of the pair of belt portions 20 on one side in the lateral direction is also referred to as a first belt portion 21, and the one on the other side in the lateral direction is also referred to as a second belt portion 22. In addition, one of the pair of leg gathers 30 in the horizontal direction is also called a first leg gather part 31, and the other in the horizontal direction is also called a second leg gather part 32.

また、吸収性物品１には、吸収性本体１０及び一対のレッグギャザー部３０のそれぞれに、一対のベルト部２０のそれぞれを接合する一対の接合部２が、前後方向の前側及び後側にそれぞれ設けられている。接合部２は、縦方向において、胴回り開口部側ＢＨから脚回り開口部ＬＨに向かって、横方向の外側へ傾斜している。   Further, in the absorbent article 1, a pair of joint portions 2 for joining the pair of belt portions 20 to the absorbent main body 10 and the pair of leg gather portions 30, respectively, on the front side and the rear side in the front-rear direction, respectively. Is provided. The joint portion 2 is inclined outward in the lateral direction from the waistline opening side BH toward the leghole opening LH in the vertical direction.

具体的には、前後の第１接合部２Ａにおいて、吸収性本体１０の縦方向の上方且つ横方向の一方側の側部、及び、第１レッグギャザー部３１の縦方向の上端部に、第１ベルト部２１の横方向の内側端部が接合されている。また、前後の第２接合部２Ｂにおいて、吸収性本体１０の縦方向の上方且つ横方向の他方側の側部、及び、第２レッグギャザー部３２の縦方向の上端部に、第２ベルト部２２の横方向の内側端部が接合されている。   Specifically, in the front and rear first joints 2A, the upper side of the absorbent body 10 in the vertical direction and the side on one side in the horizontal direction, and the upper end of the first leg gathers 31 in the vertical direction The inner end of the belt portion 21 in the horizontal direction is joined. Further, in the front and rear second joint portions 2B, the second belt portion is provided on the upper side in the longitudinal direction of the absorbent main body 10 and on the other side in the lateral direction, and on the upper end portion in the longitudinal direction of the second leg gather portion 32. The inner end of 22 in the horizontal direction is joined.

なお、接合部２の形成方法として、例えばヒートシールや超音波シール等の溶着処理や接着剤による接着処理等を例示できる。以下の説明では、一対の接合部２のうち横方向の一方側のものを第１接合部２Ａ、横方向の他方側のものを第２接合部２Ｂとも呼ぶ。また、接合部２は、非肌側面に形成され、且つ、脚回り開口部ＬＨまで達していないことが好ましい。そうすることで、他の部位に比べて硬い接合部２が着用者に接触することを防ぎ、着け心地が向上する。   In addition, as a formation method of the junction part 2, the adhesion process by an adhesive process, such as heat sealing and ultrasonic sealing, an adhesive agent etc. can be illustrated, for example. In the following description, the one on the lateral side of the pair of joints 2 is also referred to as a first joint 2A, and the other on the other side in the lateral direction is also referred to as a second joint 2B. Moreover, it is preferable that the junction part 2 is formed in the non-skin side surface, and does not reach the leg periphery opening part LH. By doing so, it prevents that the hard junction part 2 contacts a wearer compared with another site | part, and a wearing comfort improves.

また、第１接合部２Ａの縦方向の上端２Ａ１と第２接合部２Ｂの縦方向の上端２Ｂ１とが横方向に離間している。よって、パンツ型状態の吸収性物品１において、胴回り開口部ＢＨは、一対のベルト部２０の縦方向の上端部、及び、吸収性本体１０の前後の縦方向の上端部により形成されている。脚回り開口部ＬＨは、ベルト部２０の縦方向の下端部、及び、レッグギャザー部３０の横方向の外側の側部により形成されている。ベルト部２０において胴回り開口部ＢＨとなる部位が図２Ｂに示すように複数回折り返されており、丈夫且つ着用者の肌への負担が軽減される構造になっている。   Further, the vertical upper end 2A1 of the first joint 2A and the vertical upper end 2B1 of the second joint 2B are spaced apart in the horizontal direction. Therefore, in the absorbent article 1 in a pants-type state, the waistline opening BH is formed by the upper end portions in the longitudinal direction of the pair of belt portions 20 and the upper end portions in the longitudinal direction before and after the absorbent main body 10. The leg opening LH is formed by a lower end portion in the vertical direction of the belt portion 20 and a lateral outer side portion of the leg gather portion 30. As shown in FIG. 2B, the belt portion 20 has a structure where the portion serving as the waistline opening BH is folded back multiple times as shown in FIG. 2B, so that the load on the skin of the wearer is reduced.

吸収性物品１はその製造過程の最終段階で図２Ａに示す平面状態となる。平面状態では、吸収性本体１０、一対のベルト部２０、及び、一対のレッグギャザー部３０の各長手方向が揃っている。また、互いの肌側面が対向するように、吸収性本体１０及び一対のレッグギャザー部３０の上に一対のベルト部２０が重ねられている。この平面状態の吸収性物品１において、一対のベルト部２０の横方向内側の各端部２０ａをそれぞれ横方向の外側に引っ張りながら、吸収性本体１０を長手方向の略中央で二つ折りすると、吸収性物品１は図１のパンツ型状態になる。   The absorbent article 1 is in the planar state shown in FIG. 2A at the final stage of the manufacturing process. In the planar state, the longitudinal directions of the absorbent main body 10, the pair of belt portions 20, and the pair of leg gather portions 30 are aligned. Moreover, the pair of belt portions 20 are stacked on the absorbent main body 10 and the pair of leg gather portions 30 so that the skin side surfaces face each other. In the absorbent article 1 in the planar state, when the absorbent main body 10 is folded in half at the approximate center in the longitudinal direction while pulling the laterally inner ends 20a of the pair of belt portions 20 outward in the lateral direction, the absorbent article 10 is absorbed. The property article 1 is in the pants-type state shown in FIG.

平面状態では、吸収性物品１を長手方向に伸長させた状態にしている。この「伸長させた状態」とは、吸収性物品１に配置された各弾性部材（後述するベルト部２０の糸状弾性部材２１等）による収縮力に抗して吸収性物品１を長手方向に伸長させ、各弾性部材が配置されている部分において実質的に皺やギャザーが視認できなくなる程度まで吸収性物品１を伸長させた状態である。つまり、吸収性物品１を構成する各部材（後述するシート部材５０における２枚のシート５１等）の寸法がその部材単体の寸法と一致又はそれに近い長さになるまで伸長させた状態である。   In the planar state, the absorbent article 1 is extended in the longitudinal direction. This “stretched state” means that the absorbent article 1 is stretched in the longitudinal direction against the contraction force of each elastic member (such as the thread-like elastic member 21 of the belt portion 20 described later) disposed on the absorbent article 1. The absorbent article 1 is stretched to such an extent that wrinkles and gathers are substantially invisible at the portion where each elastic member is disposed. That is, it is in a state in which each member constituting the absorbent article 1 (two sheets 51 in the sheet member 50 described later, for example) is stretched until it becomes equal to or close to the dimension of the member itself.

＜吸収性本体１０＞
吸収性本体１０では、厚さ方向の肌側から順に、トップシート１１と、吸収体１２と、バックシート１３と、外装シート１４が積層されている。また、吸収性本体１０の長手方向の両端部（パンツ型状態における縦方向の上端部）には、吸収体１２よりも厚さ方向の肌側に、一対の端部シート１５が設けられている。 <Absorptive body 10>
In the absorptive main body 10, the top sheet 11, the absorber 12, the back sheet 13, and the exterior sheet | seat 14 are laminated | stacked in order from the skin side of the thickness direction. A pair of end sheets 15 are provided on the skin side in the thickness direction of the absorbent body 12 at both ends in the longitudinal direction of the absorbent main body 10 (upper end in the vertical direction in the pants-type state). .

The back sheet 13 may be a liquid impermeable sheet, and examples thereof include a polyethylene film and a polypropylene film. The top sheet 11 and the back sheet 13 are sized to cover the entire absorbent body 12. The top sheet 11 of the present embodiment has both lateral sides folded into the non-skin side surface side of the absorbent body 12. The exterior sheet 14 and the end sheet 15 may be liquid permeable sheets or liquid impermeable sheets, and are preferably flexible sheets such as nonwoven fabrics.

吸収体１２は、液体を吸収する吸収性コア１２１、及び、吸収性コア１２１の外周面を被覆するコアラップシート１２２を備えている。吸収性コア１２１は、液体吸収性素材が所定の形状に成形されたものであり、本実施形態では長手方向の両端が湾曲した略長方形状をなしている。液体吸収性素材としては、パルプ繊維等の液体吸収性繊維に高吸収性ポリマー（所謂ＳＡＰ）等が含有されたものを例示できる。コアラップシート１２２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。なお、コアラップシート１２２はなくてもよい。   The absorbent body 12 includes an absorbent core 121 that absorbs liquid, and a core wrap sheet 122 that covers the outer peripheral surface of the absorbent core 121. The absorbent core 121 is formed by molding a liquid absorbent material into a predetermined shape. In the present embodiment, the absorbent core 121 has a substantially rectangular shape with curved ends in the longitudinal direction. As a liquid absorptive material, what contained superabsorbent polymer (what is called SAP) etc. in liquid absorptive fibers, such as a pulp fiber, can be illustrated. Examples of the core wrap sheet 122 include liquid permeable sheets such as tissue paper and nonwoven fabric. The core wrap sheet 122 may not be provided.

また、吸収性本体１０（吸収性コア１２１）は複数の圧搾領域４０を有する。圧搾領域４０は、厚さ方向において少なくとも吸収性コア１２１の一部が圧搾された（エンボス加工された）領域であり、吸収性コア１２１の密度が周囲に比べて高く、厚さ方向に凹んでいる領域である。具体的には、圧搾領域４０として、厚さ方向の肌側からトップシート１１及び吸収体１２の厚さ方向の全部が圧搾された形態、トップシート１１及び吸収体１２の厚さ方向の一部が圧搾された形態、厚さ方向の非肌側からバックシート１３及び吸収体１２が圧搾された形態等を例示できる。   Moreover, the absorptive main body 10 (absorbent core 121) has the some pressing area 40. FIG. The compressed region 40 is a region in which at least a part of the absorbent core 121 is compressed (embossed) in the thickness direction, and the density of the absorbent core 121 is higher than that of the surrounding area and is recessed in the thickness direction. It is an area.

The form by which the back sheet | seat 13 and the absorber 12 were squeezed from the non-skin side of the thickness direction and the non-skin side can be illustrated.

なお、圧搾領域４０と周囲との密度の比較は周知の方法で行えばよい。例えば、吸収性コア１２１を厚さ方向に切った断面を電子顕微鏡等により撮影し、圧搾領域４０と周囲の部位とで密度差を目視で比較したり、各部位の液体吸収性素材の数を数えて比較したりするとよい。その他、圧搾領域４０と周囲の部位とを吸収性コア１２１から切り出して、各部位の質量を面積で除することで坪量（ｇ／ｃｍ2）を算出し、その坪量を厚さで除することで密度（ｇ／ｃｍ3）を算出して比較してもよい。 In addition, what is necessary is just to perform the comparison of the density of the pressing area | region 40 and the circumference | surroundings by a known method. For example, a cross section obtained by cutting the absorbent core 121 in the thickness direction is photographed with an electron microscope or the like, and the density difference between the squeezed region 40 and the surrounding portion is visually compared, or the number of liquid absorbent materials in each portion is determined. Count and compare. In addition, the pressing area 40 and surrounding parts are cut out from the absorbent core 121, and the basis weight (g / cm 2 ) is calculated by dividing the mass of each part by the area, and the basis weight is divided by the thickness. Thus, the density (g / cm 3 ) may be calculated and compared.

＜ベルト部２０及びレッグギャザー部３０＞
パンツ型状態の吸収性物品１において、ベルト部２０は横方向に伸縮し、レッグギャザー部３０は縦方向に伸縮する。よって、吸収性物品１は着用者の胴回りや脚回りにフィットする。そのために、ベルト部２０では、ベルト部２０の長手方向（略横方向）に沿った複数の糸状弾性部材２３がベルト部２０の幅方向（略縦方向）に並ぶ。レッグギャザー部３０では、縦方向に沿った複数（ここでは２本）の糸状弾性部材３３が横方向に並ぶ。そして、ベルト部２０及びレッグギャザー部３０の脚回り開口部ＬＨに沿う部位にシート状弾性部材５２が配置されている。 <Belt part 20 and leg gather part 30>
In the absorbent article 1 in a pants-type state, the belt portion 20 expands and contracts in the horizontal direction, and the leg gather portion 30 expands and contracts in the vertical direction. Therefore, the absorbent article 1 fits around the wearer's waist and legs. Therefore, in the belt portion 20, a plurality of thread-like elastic members 23 along the longitudinal direction (substantially lateral direction) of the belt portion 20 are arranged in the width direction (substantially longitudinal direction) of the belt portion 20. In the leg gather portion 30, a plurality (two in this case) of the thread-like elastic members 33 along the vertical direction are arranged in the horizontal direction. And the sheet-like elastic member 52 is arrange | positioned in the site | part along the leg periphery opening part LH of the belt part 20 and the leg gather part 30. As shown in FIG.

In the sheet member 50, the thread-like elastic members 23 and 33 of the belt portion 20 and the leg gather portion 30 and the sheet-like elastic member 52 are fixed in an extended state between the two sheets 51. The two sheets 51 are preferably flexible sheets such as nonwoven fabric. Further, a hole (LH) for the leg opening is cut out at a portion of the sheet member 50 where the sheet-like elastic member 52 exists.

吸収性物品１の製造過程では、吸収性本体１０の横方向の両側に一対のシート部材５０が配置される。詳しくは、吸収体１２とバックシート１３の間に各シート部材５０の横方向内側の端部が介挿され接合される。そして、シート部材５０の長手方向に沿い且つ脚回り開口部用の孔（ＬＨ）を通過する折り返し線ＦＬにて、シート部材５０は吸収性本体１０の肌側面側に折り返される。シート部材５０のうち折り返し線ＦＬを境に吸収性本体１０と厚さ方向に重なる部位がベルト部２０となり、吸収性本体１０と横方向に並ぶ部位がレッグギャザー部３０となる。そして、一対の接合部２が形成されることで、シート部材５０の折り返し状態が固定され、図２に示す平面状態の吸収性物品１が形成される。なお、ベルト部２０とレッグギャザー部３０が別部材で形成されていてもよい。   In the manufacturing process of the absorbent article 1, a pair of sheet members 50 are disposed on both sides of the absorbent main body 10 in the lateral direction. Specifically, the end portion on the inner side in the lateral direction of each sheet member 50 is inserted and joined between the absorber 12 and the backsheet 13. Then, the sheet member 50 is folded back to the skin side surface side of the absorbent main body 10 along a folding line FL that passes along the longitudinal direction of the sheet member 50 and passes through the hole (LH) for the leg opening. A portion of the sheet member 50 that overlaps the absorbent main body 10 in the thickness direction with the fold line FL as a boundary is the belt portion 20, and a portion that is aligned with the absorbent main body 10 in the lateral direction is the leg gather portion 30. Then, by forming the pair of joint portions 2, the folded state of the sheet member 50 is fixed, and the absorbent article 1 in a planar state shown in FIG. 2 is formed. In addition, the belt part 20 and the leg gather part 30 may be formed by another member.

The plurality of compressed regions 40 have a symmetrical shape with respect to the longitudinal center line CL1 that bisects the absorbent main body 10 in the lateral direction.

具体的には、吸収性コア１２１の前身頃域１２１Ａに、長手方向の前側から、略円形であり横方向の中央に位置する第１圧搾領域４１と、長手方向に延び且つ横方向に間隔を空けて並ぶ一対の第２圧搾領域４２及び一対の第３圧搾領域４３と、一対の第３圧搾領域４３間を横方向に延びる第４圧搾領域４４が設けられている。股下域１２１Ｂには、股下域１２１Ｂのほぼ全域に亘って長手方向に延び且つ横方向に間隔を空けて並ぶ一対の第５圧搾領域４５が設けられている。後身頃域１２１Ｃの長手方向の前側には、長手方向に延び且つ横方向に間隔を空けて並ぶ一対の第６圧搾領域４６、一対の第７圧搾領域４７、及び一対の第８圧搾領域４８が設けられている。   Specifically, from the front side in the longitudinal direction to the front body region 121A of the absorbent core 121, the first pressing region 41 that is substantially circular and located in the center in the lateral direction, and extends in the longitudinal direction and spaced apart in the lateral direction. A pair of second pressing regions 42 and a pair of third pressing regions 43 arranged side by side and a fourth pressing region 44 extending in the lateral direction between the pair of third pressing regions 43 are provided. The crotch region 121B is provided with a pair of fifth squeezing regions 45 that extend in the longitudinal direction over almost the entire region of the crotch region 121B and are arranged at intervals in the lateral direction. A pair of sixth pressing regions 46, a pair of seventh pressing regions 47, and a pair of eighth pressing regions 48 that extend in the longitudinal direction and are arranged at intervals in the lateral direction are arranged on the front side in the longitudinal direction of the rear body region 121C. Is provided.

圧搾領域４０は、その領域の全域が凹んだ溝状の領域であってもよいし、複数の凹部が間隔を空けて並び断続的に凹んだ領域であってもよい。本実施形態の圧搾領域４０では、図６に示すように平面形状が正方形である複数の凹部４０Ａが並んでいる。凹部４０Ａの平面形状は正方形以外の形状であってもよい。また、圧搾領域４０が異なる平面形状の凹部４０Ａを有していてもよい。また異なる深さの凹部４０Ａが混在していてもよい。また、圧搾領域４０内での凹部４０Ａの間隔（外形同士の間隔）は、その圧搾領域４０が１つのパターンと視認される程の狭い間隔とする。具体的には、圧搾領域４０が有する最大の凹部４０Ａの最大長さ（例えば図６のｄ１）よりも凹部４０Ａの間隔（例えば図６のｄ２）が狭いものとする。   The compressed region 40 may be a groove-like region where the entire region is recessed, or may be a region where a plurality of recesses are arranged intermittently and spaced apart. In the pressing area 40 of the present embodiment, as shown in FIG. 6, a plurality of recesses 40 </ b> A whose planar shape is a square are arranged. The planar shape of the recess 40A may be a shape other than a square. Moreover, you may have the recessed part 40A of the planar shape from which the pressing area | region 40 differs.

ところで、パンツ型の吸収性物品１では、特に女性用品である生理用として利用される場合や大人用のおむつとして利用される場合に、下着らしい外観が求められる。前述のように、吸収性物品１では、一対の接合部２がそれぞれ、縦方向において、胴回り開口部ＢＨ側から脚回り開口部ＬＨ側に向かって、横方向の外側へ傾斜している。そのため、例えば接合部が縦方向に沿ったものに比べると、吸収性物品１は下着らしい外観となっている。また、一対の接合部２間には横方向に沿う弾性部材が配されず、一対の接合部２間は横方向に伸縮しない。そのため、例えば胴回りの全周に亘って糸状弾性部材が配されたものに比べると、吸収性物品１は下着らしい外観となっている。   By the way, the underpants-type absorbent article 1 is required to have an appearance that looks like underwear, particularly when used as a sanitary garment, which is a female product, or when used as an adult diaper. As described above, in the absorbent article 1, the pair of joint portions 2 each incline outward in the lateral direction from the waistline opening BH side to the leghole opening LH side in the vertical direction. Therefore, for example, the absorbent article 1 has an appearance that seems to be underwear as compared with a case where the joint portion is along the vertical direction. Further, an elastic member extending in the lateral direction is not disposed between the pair of joint portions 2, and the pair of joint portions 2 does not expand or contract in the lateral direction. Therefore, for example, the absorbent article 1 has an appearance that seems to be underwear as compared with a case where a thread-like elastic member is arranged over the entire circumference of the trunk.

また、一対の接合部２間を横方向に伸縮させないことで、伸縮領域が減り、締め付け感を抑えられる。また、歩行時等に吸収性物品１の前後に動く臀部や脚の動きが弾性部材に阻害されない。よって、吸収性物品１では着け心地も向上する。   Further, by not expanding or contracting between the pair of joint portions 2 in the lateral direction, the expansion and contraction area is reduced, and the tightening feeling can be suppressed. Moreover, the movement of the buttocks and legs that move back and forth of the absorbent article 1 during walking or the like is not hindered by the elastic member. Therefore, the wearing comfort of the absorbent article 1 is also improved.

その一方で、吸収性物品１の着用時、一対のベルト部２０はそれぞれ横方向の外側であり斜め上方へ引き上げられる。それに伴って、吸収性本体１０は一対の接合部２を介して横方向の両外側であり接合部２の直交方向へ引っ張られる。そうすると、一対の接合部２間及びその近傍の吸収性本体１０には、図５に示すように、接合部２に沿う方向に幅入りしようとする力Ｆが働く。しかし吸収性物品１では一対の接合部２間の吸収性本体１０を着用者に密着させる弾性部材が配されていない。そのため、幅入りしようとする力Ｆによって、一対の接合部２間及びその近傍の吸収性本体１０に皺やよれが生じ易くなっている。例えば横方向に沿う皺や接合部２に直交する方向に沿う皺が生じ易くなっている。また、吸収性本体１０のうち特に吸収性コア１２１に皺やよれが生じると、***物が漏れ易くなってしまう。   On the other hand, when the absorbent article 1 is worn, the pair of belt portions 20 are respectively laterally outward and pulled up obliquely upward. Accordingly, the absorbent main body 10 is pulled outward in the transverse direction through the pair of joint portions 2 and in the orthogonal direction of the joint portion 2. If it does so, as shown in FIG. 5, the force F which tries to enter into the width | variety along the junction part 2 will act on the absorptive main body 10 between a pair of junction parts 2, and its vicinity. However, the absorbent article 1 is not provided with an elastic member that closely adheres the absorbent main body 10 between the pair of joint portions 2 to the wearer. Therefore, wrinkles and kinks are easily generated in the absorbent main body 10 between the pair of joint portions 2 and in the vicinity thereof due to the force F about to enter the width. For example, wrinkles along the lateral direction and wrinkles along the direction orthogonal to the joint 2 are likely to occur. Moreover, when wrinkles and kinks occur in the absorbent core 121 in the absorbent main body 10, excrement tends to leak.

そこで、吸収性物品１では、一対の接合部２のうちの少なくとも一方の接合部２の垂直二等分線Ｌｂと交差する方向に長さを有する圧搾領域４０であって、その垂直二等分線Ｌｂ上に存在し、且つ、縦中心線ＣＬ１に対して、その接合部２と横方向の同じ側に存在する圧搾領域４０を、吸収性コア１２１が有するようにしている。このような圧搾領域４０（本発明における圧搾領域）を別の圧搾領域４０と区別するために、以下の説明では「主圧搾領域」とも呼ぶ。なお、接合部２が幅を有する領域である場合、接合部２の一端（例えば図５の２Ａ１）上の或る点と、接合部２の他端（例えば図５の２Ａ２）上の或る点とを繋ぐ線の垂直二等分線を、接合部２の垂直二等分線Ｌｂとするとよい。   So, in the absorbent article 1, it is the pressing area | region 40 which has length in the direction which cross | intersects the perpendicular bisector Lb of at least one junction part 2 of a pair of junction parts 2, Comprising: The perpendicular | vertical bisection The absorbent core 121 has a pressing region 40 that exists on the line Lb and that exists on the same side in the lateral direction as the joint 2 with respect to the longitudinal center line CL1. In order to distinguish such a pressing area 40 (pressing area in the present invention) from another pressing area 40, it is also referred to as a “main pressing area” in the following description. When the junction 2 is a region having a width, a certain point on one end (for example, 2A1 in FIG. 5) of the junction 2 and a certain point on the other end (for example, 2A2 in FIG. 5). The vertical bisector of the line connecting the points may be the vertical bisector Lb of the joint 2.

本実施形態では第１圧搾領域４１が主圧搾領域に相当する。具体的には、前後方向（長手方向）の前側において、第１圧搾領域４１は、図６に示すように、前側の第１接合部２Ａの垂直二等分線Ｌｂ１と交差する方向Ｄ１に長さｄ３を有し、且つ、その垂直二等分線Ｌｂ１上に存在する。そして、第１圧搾領域４１において垂直二等分線Ｌｂ１と交差する方向Ｄ１に長さｄ３を有する部位が、縦中心線ＣＬ１に対して第１接合部２Ａと横方向の同じ側に存在する。また、第１圧搾領域４１は、前側の第２接合部２Ｂの垂直二等分線Ｌｂ２と交差する方向にも長さｄ４を有し、その長さｄ４を有する部位が垂直二等分線Ｌｂ２上に存在し、且つ、縦中心線ＣＬ１に対して第２接合部２Ｂと横方向の同じ側に存在する。   In the present embodiment, the first pressing area 41 corresponds to the main pressing area. Specifically, on the front side in the front-rear direction (longitudinal direction), as shown in FIG. 6, the first pressing region 41 is long in a direction D1 that intersects the vertical bisector Lb1 of the first first joining portion 2A. And d3 on the perpendicular bisector Lb1. And the site | part which has length d3 in the direction D1 which cross | intersects the perpendicular bisector Lb1 in the 1st pressing area | region 41 exists in the 1st junction part 2A and the same side of a horizontal direction with respect to the longitudinal centerline CL1. Moreover, the 1st pressing area | region 41 has length d4 also in the direction which cross | intersects the perpendicular bisector Lb2 of the 2nd junction part 2B of the front side, and the site | part which has the length d4 is the perpendicular | vertical bisector Lb2 It exists on the same side in the horizontal direction as the second joint 2B with respect to the vertical center line CL1.

圧搾領域４０が設けられた吸収性コア１２１の部位は剛性が高まり変形し難くなる。そのため、上記のように、接合部２に沿う方向に幅入りしようとする力Ｆが働く吸収性コア１２１に、接合部２に沿う方向又はそれに近い方向、つまり、接合部２の垂直二等分線Ｌｂと交差する方向に長さを有する主圧搾領域を設けるとよい。そうすることで、その主圧搾領域（本実施形態では第１圧搾領域４１）が幅入りしようとする力Ｆに抗して吸収性コア１２１を平面形状に保とうとする。よって、一対の接合部２間及びその近傍の吸収性コア１２１に生じる皺やよれを軽減できる。その結果、***物の漏れを抑制できる。また、着用者の着け心地や外観も向上する。   The portion of the absorbent core 121 provided with the compressed region 40 has increased rigidity and is difficult to deform. Therefore, as described above, the absorbent core 121 in which the force F that attempts to enter the width in the direction along the joint 2 acts on the absorbent core 121 in the direction along or near the joint 2, that is, the perpendicular bisect of the joint 2. It is good to provide the main pressing area | region which has length in the direction which cross | intersects the line Lb. By doing so, it is going to keep the absorptive core 121 in a planar shape against the force F which the main pressing area | region (1st pressing area 41 in this embodiment) tries to enter into width. Therefore, wrinkles and kinks that occur in the absorbent core 121 between the pair of joint portions 2 and in the vicinity thereof can be reduced. As a result, excrement leakage can be suppressed. In addition, the wearability and appearance of the wearer are improved.

また、吸収性物品１の引き上げ時、ベルト部２０からの引き上げ力は、接合部２の中心を基点に吸収性本体１０に掛かり、接合部２の垂直二等分線Ｌｂ上において強くなる。そのため、圧搾領域４０（第１圧搾領域４１）を垂直二等分線Ｌｂ上に存在させることで、吸収性コア１２１の皺やよれをより確実に軽減できる。つまり、垂直二等分線Ｌｂ上やその近傍の、皺やよれが生じ易い部位に、圧搾領域４０が設けられることになり、吸収性コア１２１の平面形状がより保たれ易くなる。   Further, when the absorbent article 1 is pulled up, the pulling force from the belt portion 20 is applied to the absorbent main body 10 with the center of the joint portion 2 as a base point, and becomes stronger on the vertical bisector Lb of the joint portion 2. Therefore, the wrinkle and the twist of the absorptive core 121 can be more reliably reduced by making the pressing area 40 (first pressing area 41) exist on the vertical bisector Lb. That is, the squeezing region 40 is provided on the vertical bisector Lb or in the vicinity thereof where wrinkles or kinks are likely to occur, and the planar shape of the absorbent core 121 is more easily maintained.

また、第１接合部２Ａを介した第１ベルト部２１からの引っ張り力は主に、縦中心線ＣＬ１に対して、第１接合部２Ａ側の吸収性コア１２１に働き、第２接合部２Ｂを介した第２ベルト部２２からの引っ張り力は主に、縦中心線ＣＬ１に対して、第２接合部２Ｂ側の吸収性コア１２１に働く。そのため、ある接合部２の垂直二等分線Ｌｂと交差する方向に長さを有する等した主圧搾領域を、縦中心線ＣＬ１に対して、その接合部２と横方向の同じ側に設けるとよい。   Further, the tensile force from the first belt portion 21 via the first joint portion 2A mainly acts on the absorbent core 121 on the first joint portion 2A side with respect to the longitudinal center line CL1, and the second joint portion 2B. The pulling force from the second belt portion 22 via mainly acts on the absorbent core 121 on the second joint portion 2B side with respect to the longitudinal center line CL1. Therefore, when a main squeezing region having a length in a direction intersecting the vertical bisector Lb of a certain joint 2 is provided on the same side in the lateral direction as the joint 2 with respect to the longitudinal center line CL1. Good.

なお、接合部２の垂直二等分線Ｌｂと交差する方向に圧搾領域４０が有する長さは、圧搾領域４０の幅長さでもよいが、圧搾領域４０が延びる方向の長さであることが好ましい。例えば圧搾領域４０が有する複数の凹部４０Ａが並ぶ方向の長さや圧搾領域４０の溝が延びる方向の長さであることが好ましい。そうすることで、垂直二等分線Ｌｂと交差する方向の広い範囲に亘って圧搾領域４０が存在することになり、吸収性コア１２１の平面形状がより保たれ易くなる。よって、吸収性コア１２１の皺やよれをより一層軽減できる。   In addition, although the length which the pressing area 40 has in the direction which cross | intersects the perpendicular bisector Lb of the junction part 2 may be the width length of the pressing area 40, it may be the length of the direction where the pressing area 40 extends. preferable. For example, it is preferable that it is the length of the direction where the some recessed part 40A which the pressing area | region 40 has is located, or the length of the direction where the groove | channel of the pressing area 40 extends. By doing so, the pressing area | region 40 will exist over the wide range of the direction which cross | intersects the perpendicular bisector Lb, and it becomes easier to maintain the planar shape of the absorptive core 121 more. Therefore, wrinkles and kinks of the absorbent core 121 can be further reduced.

また、第１接合部２Ａ側の皺等を軽減する主圧搾領域と、第２接合部２Ｂ側の皺等を軽減する主圧搾領域とが異なっていてもよい。例えば、横方向一方側の第２圧搾領域４２は第１接合部２Ａの垂直二等分線Ｌｂ１と交差する方向に長さを有し、横方向他方側の第２圧搾領域４２は第２接合部２Ｂの垂直二等分線Ｌｂ２と交差する方向に長さを有する。そのため、図示しないが、垂直二等分線Ｌｂ１が横方向一方側の第２圧搾領域４２を通過し、垂直二等分線Ｌｂ２が横方向他方側の第２圧搾領域４２を通過するようにしてもよい。   Moreover, the main pressing area | region which reduces the wrinkles etc. on the 1st junction part 2A side and the main pressing area which reduces wrinkles etc. on the 2nd junction part 2B side may differ. For example, the second pressing region 42 on one side in the horizontal direction has a length in a direction intersecting the vertical bisector Lb1 of the first joint portion 2A, and the second pressing region 42 on the other side in the horizontal direction is the second joint. It has a length in a direction intersecting the vertical bisector Lb2 of the portion 2B. Therefore, although not shown, the vertical bisector Lb1 passes through the second compressed region 42 on one side in the horizontal direction, and the vertical bisector Lb2 passes through the second compressed region 42 on the other side in the horizontal direction. Also good.

また、吸収性コア１２１が有する複数の圧搾領域４０が縦中心線ＣＬ１に対して非対称な形状であってもよい。そのため、吸収性コア１２１が、一対の接合部２のうちの一方の接合部２側の皺等を軽減する主圧搾領域を有するが、他方の接合部２側の皺等を軽減する主圧搾領域を有さない形態でもよい。   In addition, the plurality of compressed regions 40 included in the absorbent core 121 may have an asymmetric shape with respect to the longitudinal center line CL1. Therefore, although the absorptive core 121 has the main pressing area | region which reduces the wrinkles etc. of the one junction part 2 side of a pair of junction parts 2, the main pressing area | region which reduces the wrinkles etc. of the other junction part 2 side It may be a form that does not have.

また、主圧搾領域が接合部２の垂直二等分線Ｌｂ上に存在するとは、主圧搾領域の端が垂直二等分線Ｌｂ上に位置するだけでもよい。但し、主圧搾領域が垂直二等分線Ｌｂに交差していることが好ましい。本実施形態では、図６に示すように、第１接合部２Ａの垂直二等分線Ｌｂ１と交差する方向に長さｄ３を有する第１圧搾領域４１の部位が、垂直二等分線Ｌｂ１と交差している。また、第２接合部２Ｂの垂直二等分線Ｌｂ２と交差する方向に長さｄ４を有する第１圧搾領域４１の部位が、垂直二等分線Ｌｂ２と交差している。そうすることで、ベルト部２からの引っ張り力が強く働く部位、つまり皺やよれが生じ易い部位の広い範囲に亘って主圧搾領域が設けられ、吸収性コア１２１の平面形状が保たれ易くなる。よって、吸収性コア１２１に生じる皺やよれをより一層軽減できる。   In addition, the fact that the main squeezing region exists on the vertical bisector Lb of the joint 2 may be such that the end of the main squeezing region is located on the vertical bisector Lb. However, it is preferable that the main squeezing region intersects the vertical bisector Lb. In the present embodiment, as shown in FIG. 6, the portion of the first pressing region 41 having a length d3 in the direction intersecting the vertical bisector Lb1 of the first joint 2A is the vertical bisector Lb1. Crossed. Moreover, the site | part of the 1st pressing area | region 41 which has length d4 in the direction which cross | intersects the perpendicular bisector Lb2 of 2nd junction part 2B has cross | intersected the perpendicular bisector Lb2. By doing so, a main squeezing region is provided over a wide range of sites where the tensile force from the belt portion 2 is strongly applied, that is, sites where wrinkles and kinks are likely to occur, and the planar shape of the absorbent core 121 is easily maintained. . Therefore, wrinkles and kinks that occur in the absorbent core 121 can be further reduced.

また、主圧搾領域が垂直二等分線Ｌｂと交差する方向に長さを有する方向と、垂直二等分線Ｌｂとの成す角度が４５度以上１３５度以下であることが好ましい。本実施形態では例えば図６に示すように、第１圧搾領域４１が長さｄ３を有する方向Ｄ１と、第１接合部２Ａの垂直二等分線Ｌｂ１との成す角度θ１が４５度以上１３５度以下となっている。吸収性コア１２１には接合部２に沿う方向に幅入りしようとする力Ｆが働くため、接合部２に沿う方向又はそれに近い方向に主圧搾領域（第１圧搾領域４１）が延びて長さを有するとよい。そのため、接合部２の垂直二等分線Ｌｂとの成す角度が９０度に近い方向、つまり垂直二等分線Ｌｂとの成す角度が４５度以上１３５度以下の範囲である方向に、主圧搾領域が延びて長さを有するとよい。そうすることで、主圧搾領域が幅入りしようとする力Ｆに対して効率よく確実に抗することができる。よって、吸収性コア１２１に生じる皺やよれをより一層軽減できる。   Moreover, it is preferable that the angle formed by the direction in which the main compressed region has a length in the direction intersecting the vertical bisector Lb and the vertical bisector Lb is not less than 45 degrees and not more than 135 degrees. In this embodiment, for example, as shown in FIG. 6, the angle θ1 formed by the direction D1 in which the first compressed region 41 has the length d3 and the perpendicular bisector Lb1 of the first joint 2A is 45 degrees or more and 135 degrees. It is as follows. Since the force F which tries to enter into the absorbent core 121 in the direction along the joint portion 2 acts, the main squeezing region (first squeezing region 41) extends in the direction along the joint portion 2 or in the direction close thereto, and the length. It is good to have. Therefore, in the direction in which the angle formed by the vertical bisector Lb of the joint portion 2 is close to 90 degrees, that is, in the direction in which the angle formed by the vertical bisector Lb is in the range of 45 degrees to 135 degrees, The region may extend and have a length. By doing so, the main squeezing region can efficiently and reliably resist the force F that is about to enter. Therefore, wrinkles and kinks that occur in the absorbent core 121 can be further reduced.

また、接合部２に沿う方向に延びた直線状の主圧搾領域が最も効率よく吸収性コア１２１の皺やよれを軽減できる。但し本実施形態の圧搾領域４０のようにデザイン性の高い曲線状の圧搾領域４０が採用されることが多い。主圧搾領域が曲線状である場合、主圧搾領域は複数の方向に長さを有する。よって、主圧搾領域が長さを有する複数の方向のうちの少なくとも一方向と、垂直二等分線Ｌｂとの成す角度が４５度以上１３５度であるとよい。なお、主圧搾領域が長さを有する方向としては、例えば、主圧搾領域の或る部位における幅方向に直交する方向や、主圧搾領域の横方向の一端と他端を繋ぐ方向や、主圧搾領域の近似直線に沿う方向等を例示できる。   Moreover, the linear main pressing area | region extended in the direction in alignment with the junction part 2 can reduce the wrinkle and the twist of the absorptive core 121 most efficiently. However, the curvilinear squeezing region 40 having a high design like the squeezing region 40 of the present embodiment is often employed. When the main pressing area is curved, the main pressing area has lengths in a plurality of directions. Therefore, the angle formed by at least one direction of the plurality of directions in which the main compressed region has a length and the vertical bisector Lb is preferably 45 degrees or more and 135 degrees. In addition, as a direction where a main pressing area | region has length, for example, the direction orthogonal to the width direction in a certain site | part of a main pressing area | region, the direction which connects one end and the other end of the horizontal direction of a main pressing area, and main pressing The direction along the approximate straight line of the region can be exemplified.

また、吸収性コア１２１が主圧搾領域である第１圧搾領域４１以外の圧搾領域４０を有していなくてもよい。
但し、一対の接合部２間及びその近傍の第２圧搾領域４２及び第３圧搾領域４３が、接合部２の垂直二等分線Ｌｂと交差する方向に長さ（図６のｄ５，ｄ６）を有する。そのため、垂直二等分線Ｌｂと交差する方向の広い範囲に亘って圧搾領域４０が存在し、吸収性コア１２１の平面形状が保たれ易くなる。よって、吸収性コア１２１に生じる皺やよれをより一層軽減できる。
また、一対の第５〜第８圧搾領域４５〜４８によって、吸収性コア１２１の横方向の中央部は、着用者側に凸に変形し易く、着用者の***部や臀部の割れ目に密着し易い。よって、***物の漏れをより抑制できる。 Moreover, the absorptive core 121 does not need to have the pressing area 40 other than the 1st pressing area 41 which is a main pressing area.
However, the second pressing region 42 and the third pressing region 43 in the vicinity of the pair of joint portions 2 and in the vicinity thereof have a length in a direction intersecting the vertical bisector Lb of the joint portion 2 (d5, d6 in FIG. 6). Have Therefore, the pressing area 40 exists over a wide range in the direction intersecting the vertical bisector Lb, and the planar shape of the absorbent core 121 is easily maintained. Therefore, wrinkles and kinks that occur in the absorbent core 121 can be further reduced.
Moreover, the center part of the horizontal direction of the absorptive core 121 is easy to deform | transform into a wearer side convexly by a pair of 5th-8th pressing area | regions 45-48, and adheres to the wearer's excretion part and the crack of a buttocks. easy. Therefore, the excrement leakage can be further suppressed.

また、第２圧搾領域４２と第３圧搾領域４３の接線（例えば図６のＬ３）や、第１圧搾領域４１と第２圧搾領域４２の接線（不図示）が、接合部２の垂直二等分線Ｌｂと成す角度（例えば図６のθ２）も、４５度以上１３５度以下であることが好ましい。つまり、幅入りしようとする方向である、接合部２に沿う方向又はそれに近い方向に沿って、複数の圧搾領域４０が並ぶようにするとよい。そうすることで、複数の圧搾領域４０によって幅入りしようとする力Ｆに抗することができ、吸収性コア１２１に生じる皺やよれをより一層軽減できる。   Moreover, the tangent line (for example, L3 of FIG. 6) of the 2nd pressing area | region 42 and the 3rd pressing area | region 43, and the tangent line (not shown) of the 1st pressing area | region 41 and the 2nd pressing area | region 42 are perpendicular | vertical etc. of the junction part 2. The angle formed with the segment Lb (for example, θ2 in FIG. 6) is also preferably 45 degrees or more and 135 degrees or less. That is, it is preferable that the plurality of squeezed regions 40 be arranged along the direction along the joint portion 2 or the direction close thereto, which is the direction in which the width is to be entered. By doing so, it can resist the force F which is going to enter into the width | variety by the some pressing area 40, and can reduce further the wrinkles and the twist which arise in the absorptive core 121. FIG.

また、図示しないが、吸収性物品１が主圧搾領域（本実施形態における第１圧搾領域４１）を有さない形態であってもよい。つまり、一対の接合部２のうちの少なくとも一方の接合部２に対する垂線と交差する方向に長さを有する圧搾領域４０であって、その垂線上に存在し、且つ、縦中心線ＣＬ１に対して、その接合部２と横方向の同じ側に存在する圧搾領域４０（本実施形態における第２圧搾領域４２や第３圧搾領域４３等）を少なくとも吸収性コア１２１が有していればよい。前記垂線は接合部２の何れの位置から引いた垂線であってもよい。   Moreover, although not shown in figure, the form in which the absorbent article 1 does not have a main pressing area | region (1st pressing area 41 in this embodiment) may be sufficient. That is, it is the pressing area | region 40 which has length in the direction which cross | intersects the perpendicular | vertical with respect to the at least one junction part 2 of a pair of junction parts 2, Comprising: It exists on the perpendicular and it is with respect to the longitudinal centerline CL1. And the absorptive core 121 should just have the pressing area | region 40 (The 2nd pressing area | region 42, the 3rd pressing area | region 43, etc. in this embodiment) which exist in the same side of the junction part 2 and a horizontal direction. The perpendicular may be a perpendicular drawn from any position of the joint 2.

この場合にも、接合部２に沿う方向に幅入りしようとする力Ｆに対して、接合部２に沿う方向又はそれに近い方向、つまり、接合部２に対する垂線と交差する方向に長さを有する圧搾領域４０によって、吸収性コア１２１が平面形状に保たれ易くなる。よって、一対の接合部２間及びその近傍の吸収性コア１２１に生じる皺やよれを軽減できる。また、この場合にも、圧搾領域４０が垂線と交差していたり、圧搾領域４０が長さを有する方向と垂線との成す角度が４５度以上１３５度以下であったりすると、上記と同様の効果が得られるため、より好ましい。   Also in this case, with respect to the force F about to enter the width along the joint 2, the length is in the direction along or near the joint 2, that is, in the direction intersecting the perpendicular to the joint 2. The pressing area 40 makes it easy to keep the absorbent core 121 in a planar shape. Therefore, wrinkles and kinks that occur in the absorbent core 121 between the pair of joint portions 2 and in the vicinity thereof can be reduced. Moreover, also in this case, if the compressed region 40 intersects with the vertical line, or the angle formed between the direction in which the compressed region 40 has a length and the vertical line is not less than 45 degrees and not more than 135 degrees, the same effect as above Is more preferable.

また、吸収性物品１の着用時、吸収性物品１がある程度引き上げられた後、着用者の股下に吸収性本体１０がフィットするように、ベルト部２０の下端側から手が入れられて、吸収性物品１が更に引き上げられることが多い。この場合、接合部２の下端部を基点に力が掛かり、接合部２の下端部に対して引いた垂線上において、吸収性コア１２１の皺やよれが生じ易くなる。そこで、接合部２の下端部から引いた垂線上に、その垂線と交差する方向に長さを有する圧搾領域（本実施形態における第３圧搾領域４３や第５圧搾領域４５）を、吸収性コア１２１に設けるとよい。そうすることで、吸収性コア１２１に生じる皺やよれをより確実に軽減できる。   Further, when the absorbent article 1 is worn, after the absorbent article 1 is pulled up to some extent, the hand is put in from the lower end side of the belt portion 20 so that the absorbent main body 10 fits into the wearer's crotch. In many cases, the property article 1 is further lifted. In this case, force is applied to the lower end portion of the joint portion 2 as a base point, and wrinkles and kinks of the absorbent core 121 are likely to occur on the perpendicular drawn with respect to the lower end portion of the joint portion 2. Then, on the perpendicular drawn from the lower end part of the junction part 2, the pressing area (the 3rd pressing area | region 43 and the 5th pressing area | region 45 in this embodiment) which has length in the direction which cross | intersects the perpendicular is made into an absorptive core. 121 may be provided. By doing so, the wrinkles and the twist which arose in the absorptive core 121 can be reduced more reliably.

また、パンツ型状態の吸収性物品１において、縦方向における接合部２の中心位置よりも上側に吸収性コア１２１が存在しないことが好ましい。本実施形態では、図５に示すように、第１接合部２Ａの上端２Ａ１から縦方向の長さｄ７だけ下側であり、第１接合部２Ａの下端２Ａ２から縦方向の長さｄ７だけ上側である中心位置ＣＬ２よりも下側に、吸収性コア１２１の上端１２１ａが位置している。吸収性コア１２１は厚みがあり、外観からも吸収性コア１２１の膨らみが分かってしまう。そのため、吸収性コア１２１を必要以上に長くしないことで、より下着らしい外観が得られる。   Moreover, in the absorbent article 1 in a pants-type state, it is preferable that the absorbent core 121 does not exist above the center position of the joint portion 2 in the vertical direction. In the present embodiment, as shown in FIG. 5, the vertical length d7 is below the upper end 2A1 of the first joint 2A and the vertical length d7 is above the lower end 2A2 of the first joint 2A. The upper end 121a of the absorbent core 121 is located below the center position CL2. The absorbent core 121 is thick, and the swelling of the absorbent core 121 can be seen from the appearance. Therefore, by making the absorbent core 121 not longer than necessary, an appearance that seems to be more underwear can be obtained.

また、吸収性本体１０において、吸収性コア１２１よりも上方のシートのみから構成される領域１０Ａに比べて、吸収性コア１２１に皺やよれが生じる方が、***物の漏れや着け心地の低下に影響し易い。そのため、上記のように、吸収性コア１２１を必要以上に長くせず、一対の接合部２間及びその近傍において吸収性コア１２１が存在する領域を出来る限り小さくするとよい。そうすることで、皺やよれの生じ易い吸収性コア１２１の領域を小さくできる。   Further, in the absorbent main body 10, compared to the region 10 </ b> A composed only of the sheet above the absorbent core 121, the excrement leaks and the wearing comfort is reduced when the absorbent core 121 is wrinkled or twisted. It is easy to influence. Therefore, as described above, the absorbent core 121 is not made longer than necessary, and the region where the absorbent core 121 exists between the pair of joint portions 2 and in the vicinity thereof is preferably made as small as possible. By doing so, the area | region of the absorptive core 121 which is easy to produce a wrinkle and a twist can be made small.

また、吸収性コア１２１に生じる皺やよれは前述のように主圧搾領域（第１圧搾領域４１）にて軽減できるが、シートのみから構成される領域１０Ａには主圧搾領域が存在しない。但し、一対の接合部２の間隔は縦方向の上方に向かうに従って狭くなるため、シートのみから構成される領域１０Ａには横方向に沿う規則的な皺（凹凸の高さなどが等しい皺）が生じ易い。よって、シートのみから構成される領域１０Ａと着用者との密着面積が確保され、***物の漏れが抑制される。また、本実施形態の吸収性本体１０には縦方向の上端部、つまりシートのみから構成される領域１０Ａに、端部シート１５が設けられている。よって、シートのみから構成される領域１０Ａの剛性が高まり、皺やよれの発生を軽減できる。   In addition, wrinkles and kinks that occur in the absorbent core 121 can be reduced in the main squeezing region (first squeezing region 41) as described above, but there is no main squeezing region in the region 10A composed of only the sheet. However, since the interval between the pair of joint portions 2 becomes narrower as it goes upward in the vertical direction, regular wrinkles along the horizontal direction (the wrinkles having the same height of the unevenness) are formed in the region 10A composed only of the sheet. It is likely to occur. Therefore, the contact | adherence area of 10 A of area | regions comprised only from a sheet | seat, and a wearer is ensured, and the leakage of excrement is suppressed. Moreover, the edge part sheet | seat 15 is provided in the area | region 10A comprised only in the upper end part of the vertical direction, ie, a sheet | seat, in the absorptive main body 10 of this embodiment. Therefore, the rigidity of the region 10A composed only of the sheet is increased, and the occurrence of wrinkles and kinks can be reduced.

また、吸収性物品１の前後方向の少なくとも一方側に主圧搾領域が設けられていればよい。本実施形態では、図４に示すように、吸収性コア１２１の前身頃域１２１Ａ（前側）に主圧搾領域である第１圧搾領域４１が設けられ、後身頃域１２１Ｃには主圧搾領域が設けられていない。そのため、後身頃域１２１Ｃでは圧搾領域４０が存在する領域を小さくでき、後身頃域１２１Ｃの剛性を低くできる。よって、後身頃域１２１Ｃは着用者の臀部に合わせて変形し易く、フィット性が増し、***物の後ろ漏れを抑制できる。   Moreover, the main pressing area | region should just be provided in the at least one side of the front-back direction of the absorbent article 1. FIG. In this embodiment, as shown in FIG. 4, a first compressed region 41 that is a main compressed region is provided in the front body region 121A (front side) of the absorbent core 121, and a main compressed region is provided in the rear body region 121C. It is not done. Therefore, in the back body area 121C, the area where the compressed area 40 exists can be reduced, and the rigidity of the back body area 121C can be reduced. Therefore, the back body area 121C is easily deformed in accordance with the wearer's buttocks, the fitting property is increased, and the back leakage of excrement can be suppressed.

また、吸収性物品１の着用時、前後方向の後側よりも前側が把持され易い。よって、前側に比べて後側の吸収性コア１２１の方が、ベルト部２０からの引っ張り力を受け難く、一対の接合部２間及びその近傍に皺やよれが生じ難い。そのため、後身頃域１２１Ｃに主圧搾領域が設けられていなくとも、吸収性コア１２１の皺やよれによる***物の漏れの心配が少ない。   Further, when the absorbent article 1 is worn, the front side is more easily gripped than the rear side in the front-rear direction. Therefore, the absorbent core 121 on the rear side is less likely to receive a pulling force from the belt portion 20 than the front side, so that wrinkles and kinks are less likely to occur between the pair of joint portions 2 and in the vicinity thereof. Therefore, even if the main compression area is not provided in the back body area 121 </ b> C, there is little fear of excrement leakage due to wrinkles and kinking of the absorbent core 121.

但し上記に限らず、後身頃域１２１Ｃにも主圧搾領域を設けてもよい。また、前身頃域１２１Ａに主圧搾領域（第１圧搾領域４１）を設けず、後身頃域１２１Ｃにだけ主圧搾領域を設けてもよい。   However, not limited to the above, a main squeezing region may be provided also in the rear body region 121C. Moreover, the main pressing area (first pressing area 41) may not be provided in the front body area 121A, and the main pressing area may be provided only in the rear body area 121C.

また、図４には、吸収性物品１の左側に、縦中心ＣＬ１における吸収性コア１２１の断面図を示し、吸収性物品１の下側に、股下域１２１Ｂにおける吸収性コア１２１の断面図を示す。図示するように、吸収性コア１２１は厚さの異なる領域を複数有する。また、吸収性コア１２１において、その密度をほぼ一定とする。そのため、吸収性コア１２１は吸収性コア１２１（液体吸収性素材）の坪量が異なる領域を複数有することになる。   4 shows a cross-sectional view of the absorbent core 121 at the longitudinal center CL1 on the left side of the absorbent article 1, and a cross-sectional view of the absorbent core 121 in the crotch region 121B below the absorbent article 1. Show. As illustrated, the absorbent core 121 has a plurality of regions having different thicknesses. Further, the density of the absorbent core 121 is made substantially constant. Therefore, the absorptive core 121 has a plurality of regions having different basis weights of the absorptive core 121 (liquid absorbent material).

具体的には、後身頃域１２１Ｃの長手方向の後側及び前身頃域１２１Ａに「低坪量域１２１Ｄ（例えば厚さが１５ｍｍ）」が設けられ、股下域１２１Ｂの横方向の両側部及び後身頃域１２１Ｃの長手方向の前側に「中坪量域１２１Ｅ（例えば厚さが２５ｍｍ）」が設けられ、股下域１２１Ｂの横方向の中央部に「高坪量域１２１Ｆ（例えば厚さが３５ｍｍ）」が設けられている。   Specifically, “low basis weight area 121D (for example, thickness is 15 mm)” is provided on the rear side in the longitudinal direction of the rear body area 121C and the front body area 121A, and both lateral sides and the rear of the crotch area 121B. A “medium basis weight area 121E (for example, a thickness of 25 mm)” is provided on the front side in the longitudinal direction of the body area 121C, and a “high basis weight area 121F (for example, a thickness of 35 mm) is provided at the lateral center of the crotch area 121B. Is provided.

したがって、本実施形態の吸収性コア１２１では、股下域１２１Ｂに比べて後身頃域１２１Ｃの方が、吸収性コア１２１の坪量が低くなっている。そのため、着用者の***部に当接する股下域１２１Ｂでは***物をしっかりと吸収できる。一方、後身頃域１２１Ｃでは剛性がより低下するため、後身頃域１２１Ｃは着用者の臀部に合わせて変形し易く、フィット性が増す。そのため、***物の漏れがより一層抑制される。なお、股下域１２１Ｂと後身頃域１２１Ｃとの坪量の比較は、平均坪量で比較してもよいし、最大坪量で比較してもよい。また、坪量（ｇ／ｃｍ2）の取得方法としては、例えば、吸収性コア１２１から対象となる部位を切り出して質量を測定し、その質量を面積で除する方法を例示できる。 Therefore, in the absorbent core 121 of the present embodiment, the basis weight of the absorbent core 121 is lower in the rear body region 121C than in the crotch region 121B. Therefore, excrement can be firmly absorbed in the crotch region 121B in contact with the excretion part of the wearer. On the other hand, since rigidity is further reduced in the rear body region 121C, the rear body region 121C is easily deformed in accordance with the wearer's buttocks, and the fit is increased. Therefore, the excrement leakage is further suppressed. In addition, the comparison of the basic weight of the inseam area 121B and the back body area 121C may be made by comparing the average basic weight or the maximum basic weight. Moreover, as an acquisition method of basic weight (g / cm < 2 >), the method of cutting out the site | part used as the object from the absorptive core 121, measuring mass, and dividing | segmenting the mass by an area can be illustrated, for example.

また、吸収性コア１２１では、縦中心線ＣＬ１に対する横方向の両側のそれぞれにおいて、前身頃域１２１Ａから股下域１２１Ｂに掛け、主圧搾領域である第１圧搾領域４１（本発明における圧搾領域）と、第２圧搾領域４２、第３圧搾領域４３、及び第５圧搾領域４５（本発明における別の圧搾領域）とが、ほぼ連続して縦方向（長手方向）に並んでいる。   Moreover, in the absorptive core 121, in each of the both sides of the horizontal direction with respect to the longitudinal centerline CL1, it hangs from the front body area 121A to the crotch area 121B, and the 1st pressing area 41 (pressing area in this invention) which is a main pressing area, The second pressing region 42, the third pressing region 43, and the fifth pressing region 45 (another pressing region in the present invention) are arranged almost continuously in the longitudinal direction (longitudinal direction).

ほぼ連続して縦方向に並んでいるとは、縦方向に隣り合う圧搾領域４０の縦方向の間隔（例えば図５に示す第３圧搾領域４３と第５圧搾領域４５の縦方向の間隔ｄ８）が、第１圧搾領域４１の縦方向の長さ（図５のｄ９）よりも短くなっている。具体的には、縦方向に隣り合う圧搾領域４０の縦方向の間隔が１ｃｍ以下であるとよい。また、第１圧搾領域４１と第２圧搾領域４２は縦方向において重複しているため、第１圧搾領域４１と第２圧搾領域４２の縦方向の間隔は、第１圧搾領域４１の縦方向の長さ（ｄ９）よりも短いと言える。   The fact that they are almost continuously arranged in the vertical direction means a vertical interval between the compressed regions 40 adjacent in the vertical direction (for example, a vertical interval d8 between the third compressed region 43 and the fifth compressed region 45 shown in FIG. 5). However, it is shorter than the length of the first pressing region 41 in the vertical direction (d9 in FIG. 5). Specifically, it is good that the space | interval of the vertical direction of the pressing area | region 40 adjacent to a vertical direction is 1 cm or less. Moreover, since the 1st pressing area 41 and the 2nd pressing area 42 overlap in the vertical direction, the space | interval of the vertical direction of the 1st pressing area 41 and the 2nd pressing area 42 is the vertical direction of the 1st pressing area 41. It can be said that it is shorter than the length (d9).

上記のように圧搾領域４０が設けられることで、吸収性物品１の着用時に斜め上に引き上げられるベルト部２０からの力が、縦方向にほぼ連続する圧搾領域（第１圧搾領域４１、第２圧搾領域４２、第３圧搾領域４３、第５圧搾領域４５）によって、吸収性コア１２１の前身頃域１２１Ａから股下域１２１Ｂまで伝達され易くなる。よって、股下域１２１Ｂが着用者側に引き上げられ、着用者の***口に密着するため、***物の漏れをより一層抑制できる。また、フィット性が増し、着け心地も向上する。   By providing the pressing area 40 as described above, the pressing area (the first pressing area 41, the second pressing area) in which the force from the belt portion 20 that is pulled up obliquely when the absorbent article 1 is worn is substantially continuous in the vertical direction. The compressed region 42, the third compressed region 43, and the fifth compressed region 45) are easily transmitted from the front body region 121A to the crotch region 121B of the absorbent core 121. Therefore, since the inseam area 121B is pulled up to the wearer side and closely contacts the wearer's excretion opening, the leakage of excrement can be further suppressed. In addition, the fit is increased and the wearing comfort is also improved.

なお、後側にも主圧搾領域が設けられる場合には、後身頃域１２１Ｃから股下域１２１Ｂにかけても、主圧搾領域と別の圧搾領域とがほぼ連続して縦方向に並ぶことが好ましい。また、主圧搾領域が前身頃域１２１Ａや後身頃域１２１Ｃから股下域１２１Ｂにかけて連続して延びていてもよい。これらの場合にも上記と同様の効果が得られる。   In addition, when the main pressing area is provided also on the rear side, it is preferable that the main pressing area and another pressing area are arranged substantially continuously in the vertical direction even from the back body area 121C to the crotch area 121B. Moreover, the main squeezing region may extend continuously from the front body region 121A and the back body region 121C to the crotch region 121B. In these cases, the same effect as described above can be obtained.

また、吸収性物品１では、図４に示すように、縦中心線ＣＬ１と前側の接合部２との成す角度θ３が、縦中心線ＣＬ１と後側の接合部２との成す角度θ４よりも大きくなっている。前側の角度θ３は２０〜７０度の範囲、より好ましくは３０〜６０度の範囲であるとよい。後側の角度θ４は１０〜６０度の範囲、より好ましくは２０〜５０度の範囲であるとよい。   Moreover, in the absorbent article 1, as shown in FIG. 4, the angle θ3 formed by the longitudinal center line CL1 and the front joint 2 is larger than the angle θ4 formed by the longitudinal center line CL1 and the rear joint 2. It is getting bigger. The front angle θ3 may be in the range of 20 to 70 degrees, more preferably in the range of 30 to 60 degrees. The rear angle θ4 is in the range of 10 to 60 degrees, more preferably in the range of 20 to 50 degrees.

そうすることで、接合部２の傾斜が緩やかな前側では、ベルト部２０が横方向の外側に向かって上方に傾斜する傾向となり、逆に後側では、ベルト部２０が横方向の中心に向かって上方に傾斜する傾向となる。そのため、前側では、歩行時等の着用者の脚の動きがベルト部２０により阻害されてしまうことを防止できる。一方、後側では、着用者の臀部上方に位置する仙骨部周辺にまで吸収性物品１を引き上げられる。よって、股下域１２１Ｂでの吸収性物品１のだぶつきを抑えられ、吸収性物品１のフィット性が増すため、***物の漏れを抑制できる。但し上記に限らず、角度θ３が角度θ４以下でもよい。   By doing so, the belt portion 20 tends to incline upward in the lateral direction on the front side where the slope of the joint portion 2 is gentle, and conversely on the rear side, the belt portion 20 tends to the lateral center. Tend to tilt upward. Therefore, on the front side, it is possible to prevent the movement of the wearer's leg during walking or the like from being obstructed by the belt portion 20. On the other hand, on the rear side, the absorbent article 1 is pulled up to the periphery of the sacrum located above the wearer's buttocks. Therefore, the absorbent article 1 can be prevented from bumping in the crotch region 121B, and the fit of the absorbent article 1 is increased, so that excrement leakage can be suppressed. However, not limited to the above, the angle θ3 may be equal to or smaller than the angle θ4.

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。   As mentioned above, although embodiment of this invention was described, said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. Further, the present invention can be changed or improved without departing from the gist thereof, and needless to say, the present invention includes equivalents thereof.
