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 permeable back sheet, and an absorber arranged between them.

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（ＳｕｐｅｒＡｂｓｏｒｂｅｎｔＰｏｌｙｍｅｒ、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。 Conventionally, absorbent articles such as disposable diapers (hereinafter, also simply referred to as “diapers”) in which the discharged body fluid (hereinafter, also simply referred to as “liquid”) is guided to an absorber to be absorbed are widely known. The absorbent body is an absorbent body mainly made of pulp and a super absorbent polymer (hereinafter, also referred to as “SAP”) wrapped with a covering member such as a tissue or a non-woven fabric. This absorber is thicker than the top and back sheets and may be difficult to bend to fit the wearer's skin well.

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 an absorber in which a plurality of grooves are formed and the grooves are easily bent to improve the fit to the wearer's skin.

特開２０１３−２５５５６０号公報Japanese Unexamined Patent Publication No. 2013-255560

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 absorber absorbs the liquid, the absorbing portions between the plurality of grooves formed in the absorber expand, respectively, and the plurality of absorptions are absorbed. There was a risk that the outside of the absorbent article corresponding to the part would be deformed, and others would know that they had urinated after seeing the deformation. This can be embarrassing for the wearer or his or her guardian. Therefore, there is room for improvement in diapers for improving fit.

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 prevents urination from being known to others as much as possible while improving the fit.

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 arranged between the liquid-permeable front sheet, the liquid-impermeable back sheet, and the front sheet and the back sheet, and is joined via the back sheet and the first joint portion. An absorbent article comprising an absorber and a cover sheet joined to the outer surface of the back surface sheet via a second joint, wherein the absorber is provided with a recess forming region in which a plurality of recesses are formed. It is characterized in that the first joint portion and the second joint portion are arranged so as not to overlap at least in the region of 50% or more sandwiched between the concave portion forming region and the cover sheet.

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 the 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。 Embodiments of the 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 aspects 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 including a plurality of recesses formed on the surface of the absorber and a predetermined region sandwiched between the cover sheet and a region for joining the back sheet and the absorber. , The area for joining the back sheet and the cover sheet is arranged so as not to overlap at least. With this configuration, it becomes easy to bend in the recess to improve the fit, and even if the absorber absorbs the liquid, it becomes difficult for others to understand how the absorbing part swells outward, and as a result, urination is made to others as much as possible. It becomes possible to make it unknown.

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＞
＜構成＞
図１に本発明の第１実施形態に係るおむつの一例の外観において、正面側から見た斜視図を示す。本実施形態に係るおむつ１０は、展開型使い捨ておむつであり、前身頃領域１０Ｆと、後身頃領域１０Ｒと、これら前身頃領域１０Ｆおよび後身頃領域１０Ｒをつなぐ股下領域１０Ｃとを有する。また、着用時に前身頃領域１０Ｆと後身頃領域１０Ｒとで着用者のウエストの部分を取り囲むウエスト周り開口部１０Ｗが形成されている。同様に、前身頃領域１０Ｆおよび後身頃領域１０Ｒの下端部と股下領域１０Ｃとで着用者の両脚の太股部分を取り囲む左右一対の脚周り開口部１０Ｌが形成されている。 <First Embodiment>
<Structure>
FIG. 1 shows a perspective view of an example of a diaper according to the first embodiment of the present invention as viewed from the front side. The diaper 10 according to the present embodiment is a deployable disposable diaper, and has a front body region 10F, a back body region 10R, and an inseam region 10C connecting the front body region 10F and the back body region 10R. Further, at the time of wearing, the front body area 10F and the back body area 10R form a waist circumference opening 10W that surrounds the wearer's waist portion. Similarly, a pair of left and right leg-circumferential openings 10L that surround the thighs of both legs of the wearer are formed by the lower end of the front body region 10F and the back body region 10R and the inseam 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 area 10F is located on the ventral side of the wearer, and the back body area 10R is located on the back side of the wearer. When worn, the inseam region 10C covers the wearer's inseam, and the wearer's legs are passed through the pair of left and right leg-circumferential openings 10L. Therefore, the leg circumference opening 10L is located at any of the thighs from the bases of both legs of the wearer.

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 virtual line P extends from the ventral side to the dorsal side in the central part of the diaper through the inseam part. Specifically, for example, if the waist side of the diaper is defined as the upper side and the inseam side as the lower side, the virtual line P extends along the surface of the diaper and in the vertical direction, and on the back side via the inseam portion. 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。 At the left and right end edges of the back body area 10R of the cover sheet 11 located on the outside of the diaper 10, when worn, they are overlapped with the left and right end edges of the front body area 10F and connected to form an opening 10L around the legs. A pair of left and right fastening tapes 10A to be obtained are adhered to each other. The fastening tape 10A is repeatedly peelably joined to the front patch sheet 10B adhered to the cover sheet 11 of the front body region 10F.

図２は、図１に示すおむつ１０の模式的な分解斜視図であり、図３は、本発明の第１実施形態に係る、伸張状態のおむつ１０をトップシート１４側から見た平面図である。図２の吸収体１３および図３のおむつ１０については、説明の便宜上、部分的に破断した状態をそれぞれ示している。 FIG. 2 is a schematic exploded perspective view of the diaper 10 shown in FIG. 1, and FIG. 3 is a plan view of the stretched diaper 10 according to the first embodiment of the present invention as viewed from the top sheet 14 side. be. The absorber 13 in FIG. 2 and the diaper 10 in FIG. 3 are shown in a partially broken state for convenience of explanation.

図２に示すように、本実施形態におけるおむつ１０は、外側から順に、良好な手触りを得るために薄い不織布にて形成されるカバーシート１１と、液不透過性および透湿性を有するバックシート（裏面シート）１２と、細長い吸収体１３と、液透過性を有するトップシート（表面シート）１４と、疎水性のシート部材で構成された一対の立体ギャザー（サイドシート）１５と、を重ねた積層構造を有しているものである。 As shown in FIG. 2, the diaper 10 in the present embodiment is, in order from the outside, a cover sheet 11 formed of a thin non-woven fabric in order to obtain a good feel, and a back sheet having liquid impermeableness and moisture permeability. A laminated stack of a back sheet) 12, an elongated absorber 13, a liquid-permeable top sheet (front sheet) 14, and a pair of three-dimensional gathers (side sheets) 15 composed of hydrophobic sheet members. 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 forming an opening 10L around the leg are formed on both the left and right sides of the inseam region 10C of the cover sheet 11. A pair of rubber threads 16 for forming gathers around the legs are adhered between the cover sheet 11 and the pair of three-dimensional gathers 15 in an stretched 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 having a large number of fine pores formed therein. The back sheet 12 is joined to the cover sheet 11, the absorber 13 is arranged between the back sheet 12 and the top sheet 14, and the top sheet 14 is joined to the back sheet 12 via the absorber 13. .. In the present embodiment, the details will be described later in FIG. 5, but the back sheet 12 and the cover sheet 11 are completely bonded, and the absorber 13 and the back sheet 12 are not bonded in a predetermined region. Further, of the back seat 12, the region corresponding to the upper end portion of the back body region 10R extends along the width direction of the back seat 12 and has elasticity to give the wearer an appropriate wearing feeling around the waist. Sheets 10D are 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 the present embodiment, which is located under the top sheet 14, is an absorbent main body 17 mainly composed of pulp and SAP wrapped with a covering member (core wrap) 18 such as a tissue or a non-woven fabric. The seam formed by wrapping the absorbent body 17 with the covering member 18 is formed, for example, on the upper surface of the absorbent body 13 so as to extend in the longitudinal direction, as shown in FIG. The absorber 13 of the present embodiment has an elongated shape so as to extend to the front body, inseam, and back body. Here, assuming that the front body portion to the back body portion are in the front-back (up-down) direction and the direction orthogonal to the front-back (up-down) direction is the left-right direction, the absorber 13 of the present embodiment is a rectangular one having different front-back (up-down) left-right lengths. (In FIGS. 2 and 3, the front-back (up-down) length is longer than the left-right length). The shape of the absorber 13 of the present embodiment is not limited to this, and for example, a substantially square shape having the same front-rear (up-down) left-right length and a rounded front-back (up-down) end corner. , Includes various shapes such as elliptical ones extending back and forth (up and down), circular ones, etc. Further, a pair of arc-shaped notches may be formed in the inseam portion of the absorber 13 so as to correspond to the pair of leg-circumferential openings 10L. In the present embodiment, as shown in FIG. 3, a plurality of recesses 20 are formed on the surface of the absorber 13. The recess 20 is provided, for example, by pressing a laminate of the absorber 13 and the top sheet 14 (hereinafter, also referred to as an “absorbent portion”). Further, in the present embodiment, the absorber 13 and the back sheet 12 are located in a predetermined region sandwiched between the region of the absorber 13 in which the plurality of recesses 20 are formed (see FIG. 4 described later) and the cover sheet 11. The joint portion for joining the back sheet 12 and the cover sheet 11 is arranged so as not to overlap at least (see FIGS. 5 to 7 described later). The joint is formed by hot melt, adhesive bonding, 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 absorber 13, and of the side edges extending in the longitudinal direction of the absorber 13, one side edge has a substantially linear shape and the other side edge. A notch portion 15N is formed in the vicinity of the inseam. The inner portion of the pair of three-dimensional gathers 15 is in a non-bonded state with respect to the top sheet 14, and the three-dimensional gathers 15 include a free end at a side edge portion having a substantially linear shape. As shown in FIG. 3, a thread rubber 19 which is an elastic member acting on a tensile force is arranged at the free end of the three-dimensional gather 15 in a stretched state along the longitudinal direction of the absorber 13. The pair of three-dimensional gathers 15 can be erected along both side edges of the absorber 13 in the worn state by the thread rubber 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。 <Area of absorber with multiple recesses formed>
FIG. 4 is a plan view of the absorber 13 as viewed from the top sheet 14 side according to the first embodiment of the present invention, and is a region of the absorber 13 in which a plurality of recesses 20 are formed (hereinafter, “recess formation region””. It is a figure for demonstrating an example (also called).

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 pattern on the surface of the absorber 13. With this configuration, it becomes easy to bend in the concave portion, and it is possible to improve the 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 recess-forming region may be, for example, a rectangular region extending in the longitudinal direction of the absorber 13 so as to be in contact with both side ends of the plurality of recesses 20 (left and right ends of the recess 20 in FIG. 4). As shown in FIG. 4, this rectangular region can be represented by the recess forming region N1 as the region of the absorbing portion where the recess 20 is formed. Further, the region where the recess 20 is not formed is designated as the recess non-formed 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 the present embodiment, the recess 20 is not formed up to the end in the width direction (horizontal direction in FIG. 4) of the absorbing portion of the diaper 10, but is formed in the central portion along the longitudinal direction (vertical direction in FIG. 4). It is formed in a strip shape. In the present embodiment, the recess non-forming region N2 is provided, but the present invention is not limited to this embodiment, and it goes without saying that the recess 20 may be provided up to the end of the absorber 13. Therefore, the present invention may have a configuration in which the recess non-forming region N2 is not provided. Further, the present invention allows a mode in which the recess 20 is not formed up to the end portion 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 portion. When formed up to the end, it is possible to improve air permeability and prevention of stuffiness.

＜非接合領域＞
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-joint area>
FIG. 5 is a cross-sectional view taken along the line VV in FIG. For the sake of simplification of the description, the description of the seam of the covering member 18 is omitted in FIG. 5 (the same applies to FIGS. 6 and 7 described later). In FIG. 5, the joint portion between the absorber 13 and the back sheet 12 is referred to as a first joint portion 21a, and the joint portion between the back sheet 12 and the cover sheet 11 is referred to as a second joint portion 21b.

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, in the region sandwiched between the recess forming region N1 and the cover sheet 11, the absorber 13 and the back sheet 12 are not joined, and the back sheet 12 is not joined. 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 joint portion 21b. That is, the first joint portion 21a is not arranged in the region sandwiched between the concave portion forming region N1 and the back sheet 12. Here, the region in which the first joint portion 21a is not arranged in the region sandwiched between the recess forming region N1 and the back sheet 12 is referred to as the first non-joining region 22a. Further, in the present embodiment, as shown in FIG. 5, the absorber 13 and the back sheet 12 are joined to the region sandwiched between the recess non-forming region N2 and the cover sheet 11 via the first joint portion 21a. Then, the back sheet 12 and the cover sheet 11 are joined via the second joint portion 21b. Therefore, the second joint portion 21b is arranged so as to overlap the first joint 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 two, the first joint portion 21a is arranged so as not to overlap with the first joint portion 21a.

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 an absorber, when the absorber absorbs a liquid, the absorbing portions between the plurality of grooves formed in the absorber expand, respectively. For example, the appearance of the groove gradually disappearing can be seen from the outside of the absorbent article, and there is a risk that others will know that urination has 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 concave portion forming region N1 and the cover sheet 11, before and after urination, The outside of the absorbent article is less likely to be deformed. That is, when the absorber 13 absorbs the liquid, even if the absorbing portions located between the plurality of recesses formed in the absorber expand, the deformation due to the expansion is blocked by the non-joined region. As a result of the back sheet 12 becoming less likely to be deformed, the diaper 10 is suppressed from being deformed to the outside. Therefore, it is possible to make urination difficult for others to understand.

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。 Further, with this configuration, a gap is formed between the absorber 13 and the back sheet 12, and a passage for moisture is formed. Therefore, the moisture generated from the liquid when absorbed by the absorber is a 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, it is possible to improve the air permeability.

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 absorber 13 and the backsheet 12, which leads to an improvement in the softness of the diaper 10 as a whole. In the present embodiment, the cover sheet 11 and the back sheet 12 are entirely joined via the second joint portion 21b, but the present invention is not limited to this, and in the present invention, the cover sheet 11 and the back sheet 12 are intermittently joined via the second joint portion 21b. May be joined. This further improves the softness of the diaper. Further, in the present invention, in order to further realize the softness, a mode in which a joint portion is hardly used in the region sandwiched between the concave portion forming region N1 and the cover sheet 11 is also allowed. However, in consideration of the strength of the entire diaper 10, the joint portion (first joint portion 21a and / or second joint portion 21b) may be provided appropriately.

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 arranged 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 concave portion 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 arranged if the above conditions are satisfied. With this configuration, it becomes difficult to grasp the expanded portion of the absorber 13 that has absorbed the body fluid from the outside, it becomes difficult to understand that urination has been performed around it, and the softness of the outside of the diaper 10 is improved. When the first joint portion 21a is arranged so as to overlap the second joint portion 21b in the region sandwiched between the concave portion forming region N1 and the back sheet 12, the first joint portion 21a avoids the periphery of the concave portion 20 as much as possible. It is preferable that they are arranged so as to be uniformly dispersed.
