Description

本発明は、液透過性のトップシートと、液不透過性のバックシートと、これらの間に配置される吸収体とを有する吸収性物品に関する。   The present invention relates to an absorbent article having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed therebetween.

従来、排出された体液（以下、単に「液体」とも言う）を吸収体に誘導して吸収させた使い捨ておむつ（以下、単に「おむつ」とも言う）等の吸収性物品が広く知られている。吸収体は、主にパルプと高吸水性樹脂（Ｓｕｐｅｒ Ａｂｓｏｒｂｅｎｔ Ｐｏｌｙｍｅｒ、以下「ＳＡＰ」とも言う）とからなる吸収性本体を、ティシュや不織布等の被覆部材によって包んだものである。この吸収体は、トップシートやバックシートと比較して厚いものとなっており、着用者の肌にうまくフィットするように折れ曲がりにくい場合がある。   2. Description of the Related Art Conventionally, absorbent articles such as disposable diapers (hereinafter also simply referred to as “diapers”) in which discharged body fluid (hereinafter also simply referred to as “liquid”) is guided and absorbed by an absorber are widely known. The absorbent body is obtained by wrapping an absorbent main body mainly composed of pulp and a super absorbent polymer (hereinafter also referred to as “SAP”) with a covering member such as tissue or nonwoven fabric. This absorbent body is thicker than the top sheet or the back sheet, and may not be easily bent to fit the wearer's skin.

そこで、例えば、特許文献１には、吸収体に複数の溝を形成し、その溝において折れ曲げやすくすることにより、着用者の肌に対するフィット性の向上を図ったものが開示されている。   Therefore, for example, Patent Document 1 discloses a structure in which a plurality of grooves are formed in the absorbent body, and the fitting property to the wearer's skin is improved by facilitating bending in the grooves.

特開２０１３−２５５５６０号公報JP 2013-255560 A

しかしながら、特許文献１に記載の吸収性物品では、吸収体が液体を吸収したときに、その吸収体に形成された複数の溝の間に在る吸収部分がそれぞれ膨張して、それら複数の吸収部分に対応する吸収性物品の外側がそれぞれ変形し、その様子を見て排尿したことが他人に知られてしまうおそれがあった。これは、着用者またはその保護者にとって恥ずかしいものとなる場合がある。このため、フィット性を向上させるためのおむつには改良の余地がある。   However, in the absorbent article described in Patent Document 1, when the absorbent body absorbs the liquid, the absorbent portions existing between the plurality of grooves formed in the absorbent body are expanded, and the plurality of absorbent articles are absorbed. There was a possibility that the outside of the absorbent article corresponding to the part was deformed, and it was known to others that urination was seen by seeing the state. This can be embarrassing for the wearer or his guardian. For this reason, the diaper for improving fit property has room for improvement.

本発明の目的は、フィット性を向上しつつ、排尿を他人に極力知られないような吸収性物品を提供することにある。   An object of the present invention is to provide an absorbent article that improves fit and prevents urination from being known to others as much as possible.

本発明による吸収性物品は、液透過性の表面シートと、液不透過性の裏面シートと、表面シートと裏面シートとの間に配置され、裏面シートと第１接合部を介して接合される吸収体と、裏面シートの外側表面と第２接合部を介して接合されるカバーシートと、を備える吸収性物品であって、吸収体には、複数の凹部が形成された凹部形成領域が設けられ、該凹部形成領域とカバーシートとで挟まれた５０％以上の領域には、第１接合部と第２接合部とが少なくとも重ならないように配置されることを特徴とするものである。   The absorbent article according to the present invention is disposed between a liquid-permeable top sheet, a liquid-impermeable back sheet, and the top sheet and the back sheet, and is joined to the back sheet via the first joint portion. An absorbent article comprising an absorbent body and a cover sheet joined via an outer surface of a back sheet and a second joint portion, wherein the absorbent body is provided with a recessed portion forming region in which a plurality of recessed portions are formed. In addition, in the region of 50% or more sandwiched between the recess forming region and the cover sheet, the first joint portion and the second joint portion are arranged so as not to overlap at least.

本発明によれば、フィット性を向上しつつ、排尿を他人に極力知られないようにすることが可能となる。   According to the present invention, it is possible to prevent urination from being known to others as much as possible while improving fit.

本発明による吸収性物品の実施形態について、図１から図７を参照しながら詳細に説明する。ただし、本発明は本実施形態の態様に限定されるものではない。   An embodiment of an absorbent article according to the present invention will be described in detail with reference to FIGS. 1 to 7. However, the present invention is not limited to the aspect of the present embodiment.

本実施形態に係る吸収性物品は、吸収体の表面に形成された複数の凹部を包含する領域とカバーシートとで挟まれた所定の領域には、バックシートと吸収体とを接合する領域と、バックシートとカバーシートとを接合する領域と、が少なくとも重ならないように配置されるように構成される。この構成により、凹部において折れ曲げやすくなってフィット性を向上させ、且つ、吸収体が液体を吸収しても、その吸収部分が外側に膨らむ様子が他人にわかりにくくなる結果、排尿を他人に極力知られないようにすることが可能となる。   The absorbent article according to the present embodiment includes a region that includes a plurality of recesses formed on the surface of the absorber and a predetermined region sandwiched between the cover sheet and a region that joins the back sheet and the absorber. The region where the back sheet and the cover sheet are joined is arranged so as not to overlap at least. This configuration makes it easier to bend in the recesses and improves fit, and even if the absorber absorbs liquid, it becomes difficult for others to see how the absorbing part swells outside, so urination is given to others as much as possible. It becomes possible not to know.

先ず、本発明を展開型使い捨ておむつに応用した第１実施形態を以下に説明する。   First, a first embodiment in which the present invention is applied to a deployable disposable diaper will be described below.

＜第１実施形態＞

The diaper 10 according to the present embodiment is a deployable disposable diaper, and includes a front body region 10F, a back body region 10R, and a crotch region 10C that connects the front body region 10F and the back body region 10R. Moreover, the waist periphery opening part 10W which surrounds a wearer's waist part with the front body area | region 10F and the back body area | region 10R at the time of wear is formed. Similarly, a pair of left and right leg openings 10L that surround the thighs of the wearer's legs are formed by the lower ends of the front body region 10F and the back body region 10R and the crotch region 10C.

着用時に前身頃領域１０Ｆは、着用者の腹側に位置し、後身頃領域１０Ｒは着用者の背側に位置する。そして、着用時に股下領域１０Ｃは、着用者の股下を覆い、左右一対の脚周り開口部１０Ｌに、着用者の脚がそれぞれ通された形となる。したがって、脚周り開口部１０Ｌは、着用者の両脚の付け根から太股あたりのいずれかに位置することとなる。   When worn, the front body region 10F is positioned on the wearer's ventral side, and the back body region 10R is positioned on the wearer's back side. The crotch region 10C covers the wearer's crotch when worn, and the wearer's legs are respectively passed through the pair of left and right leg openings 10L. Therefore, the leg-hole opening 10L is located anywhere from the base of the wearer's legs to around the thigh.

仮想線Ｐは、おむつ中央部において腹側から背側に向かって、股下部分を通って延びるものである。具体的には、仮想線Ｐは、例えば、おむつのウエスト側を上、股下側を下として定義すると、おむつ表面に沿って、かつ上下方向に延びると共に、股下部分を経由して、背側においても上下方向に延びるものである。   The imaginary line P extends through the crotch part from the abdomen side to the back side in the central part of the diaper. Specifically, for example, if the imaginary line P is defined with the waist side of the diaper as the upper side and the crotch side as the lower side, the phantom line P extends along the diaper surface and in the vertical direction, and passes through the crotch part on the back side. Also extends in the vertical direction.

おむつ１０の外側に位置するカバーシート１１の後身頃領域１０Ｒの左右両端縁部には、着用時に前身頃領域１０Ｆの左右両端縁部に重ね合わせてこれらをつなぎ、脚周り開口部１０Ｌを形成し得る左右一対のファスニングテープ１０Ａが接着されている。このファスニングテープ１０Ａは、前身頃領域１０Ｆのカバーシート１１上に接着されたフロントパッチシート１０Ｂに対して繰り返し剥離可能に接合される。   The left and right end edges of the back body region 10R of the cover sheet 11 positioned outside the diaper 10 are overlapped with the left and right end edges of the front body region 10F when worn, and are connected to form a leg opening 10L. A pair of left and right fastening tapes 10A to be obtained is bonded. The fastening tape 10A is bonded to the front patch sheet 10B adhered on the cover sheet 11 in the front body region 10F so as to be repeatedly peelable.

It has a structure.

カバーシート１１の股下領域１０Ｃの左右両側には、それぞれ脚周り開口部１０Ｌとなる一対の切欠き部１１Ｎが形成されている。カバーシート１１と一対の立体ギャザー１５との間には、脚周りギャザーを形成するための一対の糸ゴム１６がそれぞれ伸張状態で接着されている。   A pair of notches 11N that are respectively leg openings 10L are formed on the left and right sides of the crotch region 10C of the cover sheet 11. Between the cover sheet 11 and the pair of three-dimensional gathers 15, a pair of thread rubbers 16 for forming a leg-around gather are bonded in an extended state.

バックシート１２を構成する材料としては、例えば、微細な孔が多数形成されたポリエチレン等の樹脂からなるフィルムを挙げることができる。バックシート１２は、カバーシート１１に接合され、吸収体１３は、このバックシート１２とトップシート１４との間に配置され、この吸収体１３を介してトップシート１４がバックシート１２に接合される。本実施形態では、詳細は図５において後述するが、バックシート１２とカバーシート１１とは全面的に接合され、吸収体１３とバックシート１２とは所定の領域において接合されない。また、バックシート１２のうち、後身頃領域１０Ｒの上端部に対応する領域には、バックシート１２の幅方向に沿って延び、着用者に対してウエスト周りに適度な着用感を与えるための弾性シート１０Ｄが接合されている。   Examples of the material constituting the backsheet 12 include a film made of a resin such as polyethylene in which a large number of fine holes are formed. The back sheet 12 is bonded to the cover sheet 11, and the absorber 13 is disposed between the back sheet 12 and the top sheet 14, and the top sheet 14 is bonded to the back sheet 12 through the absorber 13. . In the present embodiment, details will be described later with reference to FIG. 5, but the back sheet 12 and the cover sheet 11 are entirely bonded, and the absorber 13 and the back sheet 12 are not bonded in a predetermined region. Further, in the backsheet 12, an area corresponding to the upper end portion of the back body area 10 </ b> R extends along the width direction of the backsheet 12, and is elastic for giving a wearer an appropriate wearing feeling around the waist. Sheet 10D is joined.

トップシート１４の下に位置する本実施形態の吸収体１３は、主にパルプとＳＡＰとからなる吸収性本体１７を、ティシュや不織布等の被覆部材（コアラップ）１８によって包んだものである。吸収性本体１７を被覆部材１８により包むことで形成される継ぎ目は、例えば、図２に示すように、吸収体１３の上面であって長手方向に延びるように形成される。本実施形態の吸収体１３は、前身頃、股下、後身頃に亘るように、細長い形状をしている。ここで、前身頃部分から後身頃部分を前後（上下）方向とし、それに直交する方向を左右方向とすると、本実施形態の吸収体１３は、前後（上下）左右の長さが異なる矩形のものである（図２および図３では、前後（上下）の長さが左右の長さより長くなっている）。なお、本実施形態の吸収体１３の形状はこれに限らず、例えば、前後（上下）左右の長さが同程度の略正方形のもの、前後（上下）端の角が丸く落とされているもの、前後（上下）に延びる楕円形のもの、円形のもの等、さまざまな形状を含む。また、吸収体１３の股下部分には、一対の脚周り開口部１０Ｌに対応するように、円弧状をなす一対の切欠き部が形成されても良い。本実施形態では、図３に示すように、吸収体１３の表面には複数の凹部２０が形成される。この凹部２０は、例えば、吸収体１３とトップシート１４の積層体（以下、「吸収部分」とも言う）を圧搾することで設けられる。また、本実施形態では、複数の凹部２０が形成された吸収体１３の領域（後述する図４を参照）とカバーシート１１とで挟まれた所定の領域には、吸収体１３とバックシート１２とを接合する接合部と、バックシート１２とカバーシート１１とを接合する接合部と、が少なくとも重ならないように配置される（後述する図５から図７を参照）。接合部は、ホットメルト、接着剤による接着や、熱融着によって形成される。   The absorbent body 13 of this embodiment located under the top sheet 14 is obtained by wrapping an absorbent main body 17 mainly made of pulp and SAP with a covering member (core wrap) 18 such as tissue or nonwoven fabric. The seam formed by wrapping the absorbent main body 17 with the covering member 18 is, for example, formed on the upper surface of the absorbent body 13 and extending in the longitudinal direction, as shown in FIG. The absorbent body 13 of this embodiment has an elongated shape so as to extend from the front body, the crotch, and the back body. Here, assuming that the front body part to the back body part are the front and rear (up and down) directions, and the direction orthogonal to the front and back parts is the left and right direction, the absorbent body 13 of the present embodiment is a rectangular thing with different front and rear (up and down) left and right lengths. (In FIG. 2 and FIG. 3, the front and rear (up and down) lengths are longer than the left and right lengths). In addition, the shape of the absorber 13 of this embodiment is not restricted to this, For example, the thing of the substantially square whose front and back (upper and lower) left and right lengths are comparable, and the corner | angular of the front and rear (up and down) end are rounded off Various shapes such as an elliptical shape extending in the front-rear direction (up and down) and a circular shape are included. Moreover, a pair of notch parts which make | form arc shape may be formed in the crotch part of the absorber 13 so as to correspond to a pair of leg periphery opening part 10L. In the present embodiment, as shown in FIG. 3, a plurality of recesses 20 are formed on the surface of the absorber 13. This recessed part 20 is provided by squeezing the laminated body (henceforth an "absorption part") of the absorber 13 and the top sheet 14, for example. In the present embodiment, the absorber 13 and the back sheet 12 are disposed in a predetermined region sandwiched between the region of the absorber 13 (see FIG. 4 described later) in which the plurality of recesses 20 are formed and the cover sheet 11.

The joint is formed by hot melt, adhesion with an adhesive, or heat fusion.

一対の立体ギャザー１５は、吸収体１３の長手方向に沿って設けられ、吸収体１３の長手方向に延びる両側縁部のうち、一方の側縁部は略直線形状を呈し、他方の側縁部には、股下付近に切欠き部１５Ｎが形成されている。一対の立体ギャザー１５の内側部分がトップシート１４に対して非接合状態となっており、立体ギャザー１５は、その略直線形状の側縁部に自由端を含む。立体ギャザー１５の自由端には、図３に示すように、引っ張り力を作用する弾性部材である糸ゴム１９が吸収体１３の長手方向に沿って伸張状態で配置されている。一対の立体ギャザー１５は、この糸ゴム１９により、着用状態において吸収体１３の両側縁部に沿って起立可能となる。   The pair of three-dimensional gathers 15 are provided along the longitudinal direction of the absorbent body 13, and one side edge portion of the side edge portions extending in the longitudinal direction of the absorbent body 13 has a substantially linear shape, and the other side edge portion. A notch 15N is formed near the crotch. The inner parts of the pair of three-dimensional gathers 15 are not joined to the top sheet 14, and the three-dimensional gathers 15 include free ends at their substantially linear side edges. As shown in FIG. 3, a rubber thread 19, which is an elastic member that acts on a tensile force, is disposed in a stretched state along the longitudinal direction of the absorbent body 13 at the free end of the three-dimensional gather 15. The pair of three-dimensional gathers 15 can stand up along both side edges of the absorbent body 13 in a worn state by the rubber thread 19.

＜複数の凹部が形成された吸収体の領域＞
図４は本発明の第１実施形態に係る、吸収体１３をトップシート１４側から見た平面図であり、複数の凹部２０が形成された吸収体１３の領域（以下、「凹部形成領域」とも言う）の一例を説明するための図である。 <Absorber region with a plurality of recesses>
FIG. 4 is a plan view of the absorbent body 13 as viewed from the top sheet 14 side according to the first embodiment of the present invention. It is also a figure for demonstrating an example.

上述したように、吸収体１３の表面には複数の凹部２０が形成される。本実施形態では、複数の凹部２０は、吸収体１３の表面に斜め格子状に形成されている。この構成により、凹部において折り曲げやすくなり、フィット性を向上させることが可能となっている。   As described above, a plurality of recesses 20 are formed on the surface of the absorber 13. In the present embodiment, the plurality of recesses 20 are formed in an oblique lattice shape on the surface of the absorber 13. With this configuration, it is easy to bend the concave portion, and it is possible to improve fit.

凹部形成領域は、例えば、複数の凹部２０の両側端部（図４では凹部２０の左右の端部）に接するように吸収体１３の長手方向に延びる矩形領域でありうる。この矩形領域は、図４に示すように、凹部２０が形成されている吸収部分の領域として、凹部形成領域Ｎ１で表すことができる。また、凹部２０が形成されていない領域を凹部非形成領域Ｎ２とする。   The recessed portion forming region can be, for example, a rectangular region extending in the longitudinal direction of the absorbent body 13 so as to be in contact with both end portions of the plurality of recessed portions 20 (left and right end portions of the recessed portion 20 in FIG. 4). As shown in FIG. 4, this rectangular region can be represented by a recess forming region N <b> 1 as an absorption portion region where the recess 20 is formed. A region where the recess 20 is not formed is referred to as a recess non-forming region N2.

本実施形態において、凹部２０は、おむつ１０の吸収部分の幅方向（図４における左右方向）の端部まで形成されているのではなく、中央部に長手方向（図４における上下方向）に沿った帯状に形成されている。本実施形態では、凹部非形成領域Ｎ２を備えているが、本発明はこの形態に限らず、吸収体１３の端部まで凹部２０が設けられていてもよいことは言うまでもない。したがって、本発明は、凹部非形成領域Ｎ２を設けない構成であってもよい。また、本発明は、凹部２０が吸収体１３の長手方向（図４における上下方向）の端部まで形成されない態様や、当該端部まで形成される態様を許容するものである。当該端部まで形成される場合には、通気性および蒸れ防止を向上させることが可能となる。   In this embodiment, the recessed part 20 is not formed to the edge part of the width direction (left-right direction in FIG. 4) of the absorption part of the diaper 10, but is along a longitudinal direction (up-down direction in FIG. 4) in the center part. It is formed in a strip shape. In this embodiment, although the recessed part non-formation area | region N2 is provided, it cannot be overemphasized that the recessed part 20 may be provided to the edge part of the absorber 13 not only in this form but the absorber. Therefore, the present invention may be configured not to provide the recess non-formation region N2. In addition, the present invention allows a mode in which the recess 20 is not formed up to the end in the longitudinal direction (vertical direction in FIG. 4) of the absorber 13 or a mode in which the recess 20 is formed up to the end. In the case of forming up to the end portion, it is possible to improve air permeability and prevention of stuffiness.

図５は、図３におけるＶ−Ｖ方向断面図である。尚、説明の簡略化のため、図５では被覆部材１８の継ぎ目の記載を省略している（後述する図６および図７も同様）。図５では、吸収体１３とバックシート１２との間にある接合部を第１接合部２１ａと表し、バックシート１２とカバーシート１１との間にある接合部を第２接合部２１ｂと表す。 <Non-bonding area>
5 is a cross-sectional view in the VV direction in FIG. For simplification of description, the joint of the covering member 18 is omitted in FIG. 5 (the same applies to FIGS. 6 and 7 described later). In FIG. 5, a joint portion between the absorber 13 and the back sheet 12 is represented as a first joint portion 21 a, and a joint portion between the back sheet 12 and the cover sheet 11 is represented as a second joint portion 21 b.

本実施形態に係るおむつ１０では、図５に示すように、凹部形成領域Ｎ１とカバーシート１１とで挟まれた領域では、吸収体１３とバックシート１２とが接合されておらず、バックシート１２の外側表面、つまり、バックシート１２のうち吸収体１３側と反対側の表面とカバーシート１１とが第２接合部２１ｂを介して接合されている。すなわち、凹部形成領域Ｎ１とバックシート１２とで挟まれた領域には、第１接合部２１ａが配置されないことになる。ここで、凹部形成領域Ｎ１とバックシート１２とで挟まれた領域における第１接合部２１ａが配置されない領域を第１非接合領域２２ａとする。また、本実施形態では、図５に示すように、凹部非形成領域Ｎ２とカバーシート１１とで挟まれた領域には、吸収体１３とバックシート１２とが第１接合部２１ａを介して接合され、バックシート１２とカバーシート１１とが第２接合部２１ｂを介して接合される。したがって、第２接合部２１ｂは、凹部非形成領域Ｎ２とカバーシート１１とで挟まれた領域では、第１接合部２１ａと重なるように配置されているが、凹部形成領域Ｎ１とカバーシート１１とで挟まれた領域には、第１接合部２１ａと重ならないように配置されている。   In the diaper 10 according to the present embodiment, as shown in FIG. 5, the absorber 13 and the back sheet 12 are not joined in the region sandwiched between the recess forming region N <b> 1 and the cover sheet 11. The outer surface of the back sheet 12, that is, the surface of the back sheet 12 opposite to the absorber 13 side and the cover sheet 11 are joined via the second joining portion 21b. That is, the first joint portion 21a is not disposed in a region sandwiched between the recess forming region N1 and the back sheet 12. Here, a region where the first joint portion 21a is not disposed in a region sandwiched between the recess forming region N1 and the back sheet 12 is referred to as a first non-joined region 22a. Moreover, in this embodiment, as shown in FIG. 5, the absorber 13 and the back sheet 12 are joined via the 1st junction part 21a to the area | region pinched | interposed by the recessed part non-formation area | region N2 and the cover sheet 11. FIG. Then, the back sheet 12 and the cover sheet 11 are joined via the second joining portion 21b. Therefore, the second bonding portion 21b is arranged so as to overlap the first bonding portion 21a in the region sandwiched between the concave portion non-forming region N2 and the cover sheet 11, but the concave portion forming region N1 and the cover sheet 11 In the region sandwiched between the first joint portion 21a and the first joint portion 21a, the first joint portion 21a is not overlapped.

従来、吸収体に複数の溝を形成したおむつ吸収性物品では、吸収体が液体を吸収したときに、その吸収体に形成された複数の溝の間に在る吸収部分がそれぞれ膨張して、例えば、当該溝部分が次第に消え去る様子が吸収性物品の外側から見え、排尿したことが他人に知られてしまうおそれがあった。   Conventionally, in a diaper absorbent article in which a plurality of grooves are formed in the absorbent body, when the absorbent body absorbs the liquid, the absorption portions existing between the plurality of grooves formed in the absorbent body are expanded, For example, the appearance that the groove portion gradually disappears was seen from the outside of the absorbent article, and there was a possibility that other people would know that urination occurred.

本発明では、凹部形成領域Ｎ１とカバーシート１１とで挟まれた所定の領域に、第１接合部２１ａと第２接合部２１ｂとを少なくとも重ならないように配置することによって、排尿の前後において、吸収性物品の外側が変形しにくくなる。すなわち、吸収体１３が液体を吸収したときに、その吸収体に形成された複数の凹部の間に在る吸収部分がそれぞれ膨張したとしても、その膨張に伴う変形が、接合されない領域によって遮られ、バックシート１２が変形しにくくなる結果、おむつ１０の外側への変形が抑制される。よって、排尿を他人にわかりにくくすることが可能となる。   In the present invention, by arranging the first joint portion 21a and the second joint portion 21b so as not to overlap at least in a predetermined region sandwiched between the recess forming region N1 and the cover sheet 11, before and after urination, The outside of the absorbent article is difficult to deform. That is, when the absorber 13 absorbs the liquid, even if the absorbing portions existing between the plurality of recesses formed in the absorber are expanded, deformation due to the expansion is blocked by the unjoined region. As a result of the back sheet 12 becoming difficult to deform, deformation to the outside of the diaper 10 is suppressed. Therefore, it becomes possible to make it difficult for others to understand urination.

また、この構成により、吸収体１３とバックシート１２との間に隙間が出来ることによって、湿気の通り道が形成されるので、吸収体に吸収される際の液体から生じる湿気は、透湿性のバックシート１２およびカバーシート１１を通り抜けおむつ１０の外側に排出されることになる。したがって、通気性が向上することが可能となる。   In addition, with this configuration, a gap is formed between the absorbent body 13 and the back sheet 12 so that a passage for moisture is formed. Therefore, moisture generated from the liquid when absorbed by the absorbent body is moisture permeable back. It passes through the sheet 12 and the cover sheet 11 and is discharged to the outside of the diaper 10. Therefore, air permeability can be improved.

さらに、この構成により、吸収体１３とバックシート１２との間に隙間が出来るので、おむつ１０全体の柔らかさの向上につながる。なお、本実施形態では、カバーシート１１とバックシート１２とが全面的に第２接合部２１ｂを介して接合されているがこれに限られず、本発明では、第２接合部２１ｂを介して間欠的に接合されてもよい。これにより、おむつの柔らかさがさらに向上する。また、本発明では、柔らかさをさらに実現するために、凹部形成領域Ｎ１とカバーシート１１とで挟まれた領域に、接合部をほとんど使用しない態様も許容するものである。しかし、おむつ１０全体の強度を考慮して、適度に接合部（第１接合部２１ａおよび／または第２接合部２１ｂ）を設ける態様であってもよい。   Further, this configuration creates a gap between the absorbent body 13 and the back sheet 12, which leads to an improvement in the softness of the entire diaper 10. In the present embodiment, the cover sheet 11 and the back sheet 12 are entirely bonded via the second bonding portion 21b. However, the present invention is not limited to this, and in the present invention, intermittently via the second bonding portion 21b. May be joined together. Thereby, the softness of a diaper further improves. Moreover, in this invention, in order to implement | achieve softness further, the aspect which hardly uses a junction part in the area | region pinched | interposed by the recessed part formation area N1 and the cover sheet 11 is also accept | permitted. However, in consideration of the strength of the diaper 10 as a whole, a mode in which a bonding portion (first bonding portion 21a and / or second bonding portion 21b) is appropriately provided may be employed.

本実施形態では、凹部形成領域Ｎ１とカバーシート１１とで挟まれた領域には、第１接合部２１ａが全く配置されない。しかし、本発明者は、凹部形成領域Ｎ１とカバーシート１１とで挟まれた５０％以上の領域において、第１接合部２１ａと第２接合部２１ｂとが少なくとも重ならないように配置されるという条件を満たせば、第１接合部２１ａが配置されなくとも、本発明の効果を有効に発揮することを発見した。この構成によって、吸収体１３のうち体液を吸収して膨張した部分が外から把握しにくくなり、周りに排尿したことがわかりにくくなる上、おむつ１０の外側のやわらかさを向上させることになる。凹部形成領域Ｎ１とバックシート１２とで挟まれた領域に、第２接合部２１ｂと重なるように第１接合部２１ａを配置する場合、その第１接合部２１ａは、凹部２０の周辺をできるだけ避けて、均一に分散するように配置されることが好ましい。   In the present embodiment, the first joint portion 21a is not disposed at all in the region sandwiched between the recess forming region N1 and the cover sheet 11. However, the present inventor has a condition that the first joint portion 21a and the second joint portion 21b are arranged so as not to overlap at least in a region of 50% or more sandwiched between the recess forming region N1 and the cover sheet 11. It has been found that the effect of the present invention is effectively exhibited even if the first joint portion 21a is not disposed if the above condition is satisfied. This configuration makes it difficult to grasp from the outside the portion of the absorbent body 13 that has absorbed body fluid and has expanded, making it difficult to recognize that the body has been urinated, and improving the softness of the outer side of the diaper 10. When the first joint portion 21a is disposed so as to overlap the second joint portion 21b in the region sandwiched between the recess formation region N1 and the back sheet 12, the first joint portion 21a avoids the periphery of the recess 20 as much as possible. And are preferably arranged so as to be uniformly dispersed.
