Description

Translated fromJapanese

本発明は、生理用ナプキン、失禁パッド等の吸収性物品に関する。  The present invention relates to absorbent articles such as sanitary napkins and incontinence pads.

従来、表面シート、裏面シート、及び両シート間に介在された吸収体を備えた実質的に縦長の吸収性本体における肌当接面側の両側部からの横漏れを防止するために、該吸収性本体における肌当接面側の両側部を一対の側部シートで覆い、サイド防漏部が設けられている吸収性物品が知られている。このようにサイド防漏部を設けることで、吸収性本体における肌当接面側の両側部に、液の拡散を抑制する領域が形成され、場合によっては立体的な壁が形成され、液が横方向へ移動することが防止される。  Conventionally, in order to prevent side leakage from both sides of the skin contact surface side in a substantially vertically long absorbent main body having a top sheet, a back sheet, and an absorbent body interposed between both sheets, the absorption is performed. 2. Description of the Related Art Absorbent articles are known in which both side portions on the skin contact surface side of an adhesive main body are covered with a pair of side sheets and side leakage preventing portions are provided. By providing the side leak-proof portion in this way, regions that suppress the diffusion of the liquid are formed on both sides of the absorbent main body on the skin contact surface side, and in some cases a three-dimensional wall is formed, The lateral movement is prevented.

例えば、特許文献1には、吸収性本体の長手方向両側部にウイング部を有するフラップが形成されており、該フラップは液バリヤーシートからなり、該液バリヤーシートをその幅方向内側縁から離間した位置において表面シートに接合して、バリヤーシートと表面シートとの間にポケットを形成した吸収性物品が開示されている。また、特許文献2には、表面シートにその左右両側部を覆うように防漏シートが接着されており、該防漏シートは、長手方向に延びる押圧溝において表面シートとともに吸収体に押圧されている吸収性物品が開示されている。  For example, inPatent Document 1, a flap having wing portions is formed on both sides in the longitudinal direction of the absorbent main body, the flap is made of a liquid barrier sheet, and the liquid barrier sheet is separated from the inner edge in the width direction. An absorbent article is disclosed in which a pocket is formed between the barrier sheet and the surface sheet by bonding to the surface sheet at the position. Further, inPatent Document 2, a leak-proof sheet is bonded to the top sheet so as to cover both the left and right sides, and the leak-proof sheet is pressed against the absorbent body together with the top sheet in a pressing groove extending in the longitudinal direction. An absorbent article is disclosed.

As shown in FIGS. 3 and 4, the pair ofcompressed grooves 6 and 6 are formed by joining theside sheet 71, thetop sheet 2, and the absorber 4. In the present embodiment, the pair ofcompressed grooves 6 and 6 are formed by embossing, and theside sheet 71, thetop sheet 2 and theabsorber 4 are joined by heat sealing. As shown in FIG. 5, the depth T1 of the pair ofcompressed grooves 6 and 6 is 50 of the thickness T4 (the total thickness of thetopsheet 2 and the absorbent body 4) of theabsorbent layer 11 at the site where thecompressed grooves 6 are not formed. -100%, preferably 70-90%. It is also preferable that the depth T1 of thecompressed groove 6 is 50 to 100%, particularly 70 to 90%, of the thickness T2 of theabsorber 4.
Moreover, the width direction innerside edge part 72 of the said side part sheet |seat 71 is not joined to thesurface sheet 2, and the free end is formed in the width direction innerside edge part 72 of the side leak-proof part 7. FIG. As described above, the sideleakage preventing portion 7 has a side that is formed by the deeply formedcompressed groove 6 and the inner end portion in the width direction of theside portion sheet 71 is not joined to thetopsheet 2. The free end of thepart sheet 71 stands in a direction away from thetop sheet 2 toward the inner side in the width direction of the absorbentmain body 10.

前記側部シート71が起立し、防漏効果を発揮するためには、図5に示すように、前記圧縮溝6の底部から前記側部シート71の幅方向内側端部72までの該側部シート71の長さL1は、前記圧縮溝6の深さT1よりも長く、且つ該圧縮溝6の底部の幅W1よりも長くなっていることが重要である。なお、本発明において圧縮溝6の底部から側部シート71の幅方向内側端部72までの該側部シート71の長さL1とは、圧縮溝6が最も幅方向内方に設けられている部分における圧縮溝6の底部から側部シート71の幅方向内端部72までの該側部シート71の長さをいう。また、圧縮溝6の底部の幅W1とは、圧縮溝6の幅(吸収性本体10の幅方向の長さ、以下同じ)が最も広い部分における圧縮溝6の底部の幅をいう。圧縮溝6の深さT1は、圧縮溝6の形成されていない部位における吸収体4の厚みT2と、圧縮溝6の形成されている部位における高さT3との差で表され、例えば圧縮溝6が多段階の深さに形成されている場合には、その最も深く形成されている部位における深さをいう。なお、圧縮溝6の形成されている部位における高さT3は、圧縮溝6の形成されていない部位における吸収体4の厚みT2の底面と同じ高さより測定をするものであり、圧縮溝6の形成されている部位の底面が、生理用ナプキン1の裏面側から突出、又は窪んでいる場合においても、圧縮溝6の形成されていない部位における吸収体4の厚みT2の底面と同じ高さより測定した高さをいう。  In order for theside sheet 71 to stand up and exhibit a leak-proof effect, as shown in FIG. 5, the side part from the bottom of thecompressed groove 6 to the widthwiseinner end 72 of theside sheet 71. It is important that the length L1 of thesheet 71 is longer than the depth T1 of thecompressed groove 6 and longer than the width W1 of the bottom of thecompressed groove 6. In the present invention, the length L1 of theside sheet 71 from the bottom of thecompressed groove 6 to the widthwiseinner end 72 of theside sheet 71 is such that thecompressed groove 6 is provided most inward in the width direction. The length of theside sheet 71 from the bottom of thecompressed groove 6 to theinner end 72 in the width direction of theside sheet 71 is said. The width W1 of the bottom of thecompressed groove 6 refers to the width of the bottom of thecompressed groove 6 at the widest portion of the compressed groove 6 (the length in the width direction of the absorbentmain body 10, the same applies hereinafter). The depth T1 of thecompressed groove 6 is represented by the difference between the thickness T2 of theabsorbent body 4 at the portion where thecompressed groove 6 is not formed and the height T3 at the portion where thecompressed groove 6 is formed. In the case where 6 is formed at a multistage depth, it means the depth at the deepest part. The height T3 at the portion where thecompressed groove 6 is formed is measured from the same height as the bottom surface of the thickness T2 of theabsorber 4 at the portion where thecompressed groove 6 is not formed. Even when the bottom surface of the formed part protrudes from the back side of thesanitary napkin 1 or is depressed, it is measured from the same height as the bottom surface of the thickness T2 of theabsorbent body 4 in the part where thecompressed groove 6 is not formed. The height.

前記圧縮溝6の底部から前記側部シート71の幅方向内側端部72までの該側部シート71の長さL1が圧縮溝6の深さT1よりも短い場合、又は圧縮溝6の底部の幅W1よりも短い場合には、側部シート71の幅方向内側端部72が圧縮溝6の内部に存在することとなり、防漏効果を発揮することができなくなる。また、圧縮溝6の底部から側部シート71の幅方向内側端部72までの該側部シート71までの長さL1は、圧縮溝6の深さT1の3倍以下であることが好ましい。圧縮溝6の底部から側部シート71の幅方向内側端部72までの該側部シート71の長さL1が圧縮溝6の深さT1の長さの3倍を超えると、側部シート71の起立性が悪くなるおそれがある。また、圧縮溝6の上面の開口幅W2は、前記圧縮溝6の底部の幅W1と同じであるか又は該圧縮溝6の底部の幅W1よりも広いことが好ましい。  When the length L1 of theside sheet 71 from the bottom of thecompressed groove 6 to the widthwiseinner end 72 of theside sheet 71 is shorter than the depth T1 of thecompressed groove 6, or at the bottom of thecompressed groove 6 When the width W1 is shorter than the width W1, the width directioninner end 72 of theside sheet 71 is present inside thecompressed groove 6, and the leakage preventing effect cannot be exhibited. The length L1 from the bottom of thecompressed groove 6 to theside sheet 71 from the widthwiseinner end 72 of theside sheet 71 is preferably not more than three times the depth T1 of thecompressed groove 6. When the length L1 of theside sheet 71 from the bottom of thecompressed groove 6 to the widthwiseinner end 72 of theside sheet 71 exceeds three times the length T1 of thecompressed groove 6, theside sheet 71 There is a risk that the orthostaticity of the will deteriorate. The opening width W2 on the upper surface of thecompressed groove 6 is preferably the same as the width W1 at the bottom of thecompressed groove 6 or wider than the width W1 at the bottom of thecompressed groove 6.

The end and the pair of outerrear grooves 53, 53 are connected. Further, the pair offront grooves 54, 54 are connected at the front end in the longitudinal direction, and the pair of outerrear grooves 53, 53 are connected at the rear end in the longitudinal direction. Therefore, in the present embodiment, a closed region surrounded by the pair offront grooves 54, 54, the pair ofcentral grooves 51, 51, and the pair of outerrear grooves 53, 53 is formed. Further, the pair of innerrear grooves 52, 52 are not connected to the pair ofcentral grooves 51, 51 and the pair of outerrear grooves 53, 53.

本実施形態においては、図3に示すように、前記中央溝51、前記内側後方溝52、前記外側後方溝53及び前記前方溝54は、吸収性本体10の厚み方向に吸収体4の非肌当接面側近傍にまで深く延びて形成されている。そのため、排泄された体液が多量であっても、体液は、中央溝51、内側後方溝52、外側後方溝53、及び前方溝54で一旦止められ、これらの溝を通って吸収体4に移動することができる。  In the present embodiment, as shown in FIG. 3, thecentral groove 51, the innerrear groove 52, the outerrear groove 53, and thefront groove 54 are non-skin of theabsorbent body 4 in the thickness direction of the absorbentmain body 10. It is formed to extend deeply to the vicinity of the contact surface side. Therefore, even if a large amount of body fluid is excreted, the body fluid is temporarily stopped at thecentral groove 51, the innerrear groove 52, the outerrear groove 53, and thefront groove 54, and moves to theabsorber 4 through these grooves. can do.

本実施形態においては、上記各溝は上述した一対の圧縮溝6,6と同様に、前記吸収性本体10の肌当接面側に、エンボス加工により形成され、前記表面シート2と前記吸収体4とがヒートシール接合されている。  In the present embodiment, each of the grooves is formed on the skin contact surface side of the absorbentmain body 10 by embossing similarly to the pair ofcompressed grooves 6 and 6 described above, and thetop sheet 2 and theabsorbent body 4 is heat-sealed.

前記表面シート2及び前記裏面シート3の形成材料としては,従来の吸収性物品等において用いられている各種のシート材料を特に制限なく用いることができる。
前記側部シート71の形成材料としては、従来の吸収性物品等において用いられている各種の撥水性を有するシート材料を用いることができ、特にポリエチレンシート、ポリエチレンラミネート紙、SMS不織布等が好ましい。
As a material for forming thetop sheet 2 and theback sheet 3, various sheet materials used in conventional absorbent articles and the like can be used without particular limitation.
As the material for forming theside sheet 71, various water-repellent sheet materials used in conventional absorbent articles and the like can be used, and polyethylene sheet, polyethylene laminated paper, SMS nonwoven fabric and the like are particularly preferable.

Further, as a material for forming theabsorbent body 4, in addition to a pulp material, a polymer-absorbing polymer, a synthetic fiber made of polyester or polypropylene, a heat-fusible fiber, or rayon can also be used. As a material for forming theabsorbent body 4, it is also preferable to use a mixture of pulp material and other materials.

本実施形態の生理用ナプキン1は、使用前においては、前方部Aと中央部Bとの境界線近傍、及び中央部Bと後方部Cとの境界線近傍を折り線として、図6に示すように、3つ折りに折り畳まれている。また、図2に示すように、前方部Aと中央部Bとの境界線近傍は、前方溝54と中央溝51との繋がり位置となっており、該繋がり位置近傍における溝(前方溝54及び中央溝51)の形状は、幅方向内側に括れた形状となっている。同様に、中央部Bと後方部Cとの境界線近傍は、中央溝51と外側後方溝53との繋がり位置となっており、該繋がり位置近傍における溝(中央溝51及び外側後方溝53)の形状は、幅方向内側に括れた形状となっている。生理用ナプキン1を使用する際には、テープ9が外されるか、テープ9がない場合はそのまま、折り畳まれている前方部A及び後方部Cそれぞれが長手方向外側に開かれる。このように、生理用ナプキン1は、括れた形状を有する前方溝54と中央溝51との繋がり位置及び中央溝51と外側後方溝53との繋がり位置付近を折り線として折り畳まれているため、曲げ誘導によって折り皺が少なく、着用時には隆起によって皺が消失もしくは緩和されるため、使用感が良く、生理用ナプキン1の表面に排泄された体液が、該皺を伝って、幅方向に漏れることを防止できる。尚、図6に示す折り畳み形状は、生理用ナプキン1単体であるが、包装シートや剥離シートとともに折り畳まれていても良い。  Thesanitary napkin 1 according to the present embodiment is shown in FIG. 6 with the vicinity of the boundary line between the front part A and the central part B and the vicinity of the boundary line between the central part B and the rear part C as folding lines before use. As shown, it is folded in three. In addition, as shown in FIG. 2, the vicinity of the boundary line between the front portion A and the central portion B is a connection position between thefront groove 54 and thecentral groove 51, and the grooves (thefront groove 54 and the groove in the vicinity of the connection position). The shape of the central groove 51) is a shape confined to the inner side in the width direction. Similarly, the vicinity of the boundary line between the central portion B and the rear portion C is a connection position between thecentral groove 51 and the outerrear groove 53, and grooves in the vicinity of the connection position (thecentral groove 51 and the outer rear groove 53). The shape is a shape that is bound to the inner side in the width direction. When thesanitary napkin 1 is used, thetape 9 is removed, or when thetape 9 is not present, the folded front part A and rear part C are opened outward in the longitudinal direction. As described above, thesanitary napkin 1 is folded with the vicinity of the connection position between thefront groove 54 and thecentral groove 51 and the connection position between thecentral groove 51 and the outerrear groove 53 having a constricted shape as fold lines. Because there are few folds due to bending induction, and the folds disappear or relieve by bulging when worn, the feeling of use is good, and body fluid excreted on the surface of thesanitary napkin 1 leaks in the width direction along the folds. Can be prevented. In addition, although the folded shape shown in FIG. 6 is thesanitary napkin 1 simple substance, you may fold with the packaging sheet and the peeling sheet.

本実施形態の生理用ナプキン1は、ショーツ等の股下部内側に固定して着用される。生理用ナプキン1の中央部Bにおける表面シート2は、着用者の排泄部に当接する。この際、生理用ナプキン1は、着用者の両太ももの付け根内側により左右から幅方向内側へ圧縮力を受ける。生理用ナプキン1は、左右から幅方向内側へ圧縮力を受けると、一対の中央溝51,51が幅方向外側に凸に湾曲していることに起因して、一対の該中央溝51,51に囲まれている吸収体4の中央部分が隆起する。  Thesanitary napkin 1 of the present embodiment is worn by being fixed to the inside of the crotch part such as shorts. Thesurface sheet 2 in the central part B of thesanitary napkin 1 contacts the excretion part of the wearer. At this time, thesanitary napkin 1 receives a compressive force from the left and right to the inner side in the width direction by the inner sides of the thighs of the wearer. When thesanitary napkin 1 receives a compressive force from the left and right inward in the width direction, the pair ofcentral grooves 51, 51 are convexly curved outward in the width direction. The central part of theabsorbent body 4 surrounded by bulges.

本実施形態の生理用ナプキン1によれば、側部シート71が表面シート2及び吸収体4とともに吸収体4の厚みの50〜100%の深さにまで圧縮されて圧縮溝が設けられているため、サイド防漏部7において側部シート71が安定的に起立し、吸収性本体10の肌当接面側の両側部における防漏性に優れる。さらに、前記圧縮溝6が多段階の深さに形成されている場合には、側部シート7に波状形状もしくは不規則な皺形状が形成され、圧縮溝6の上端よりも上面側に位置する側部シート7の起立部分が折れ難く、また曲がり難くなる点から好ましい。
また、圧縮溝6は、前記折り線S1、S2を跨いで延びている。折り線S1及びS2に囲まれた部位(中央部B)は着用者の液排泄部に対向配置される排泄部対向部位である。このように、圧縮溝6が排泄部対向部位の長手方向前方及び後方に亘って設けられていることによっても、吸収性本体10の肌当接面側の両側部における防漏性が向上する。更に、折り線S1及びS2によって生じる折り皺が側部シート7にも形成されることで、側部シート7の起立性が高められる。
According to thesanitary napkin 1 of this embodiment, theside sheet 71 is compressed to a depth of 50 to 100% of the thickness of theabsorbent body 4 together with thetop sheet 2 and theabsorbent body 4 to provide a compressed groove. Therefore, theside sheet 71 stands up stably in the side leak-proof portion 7 and is excellent in leak-proof performance at both side portions on the skin contact surface side of the absorbentmain body 10. Further, when thecompressed groove 6 is formed in a multi-stage depth, theside sheet 7 is formed with a wave shape or an irregular ridge shape, and is located on the upper surface side from the upper end of thecompressed groove 6. The standing part of theside sheet 7 is preferable because it is difficult to bend and bend easily.
Further, thecompressed groove 6 extends across the folding lines S1 and S2. The part (center part B) surrounded by the fold lines S1 and S2 is an excretion part facing part that is arranged to face the wearer's liquid excretion part. Thus, the leak-proof property in the both sides by the side of the skin contact surface of the absorptivemain body 10 improves also by providing thecompressed groove 6 over the longitudinal direction front and back of an excretion part opposing part. Furthermore, the folds produced by the fold lines S1 and S2 are also formed on theside sheet 7, so that the standing property of theside sheet 7 is enhanced.

本実施形態の生理用ナプキン1においては、上述の通り、着用時に一対の中央溝51,51に囲まれた部位が隆起する。この隆起形成によって側部シート71の起立性が増し、吸収性本体10の肌当接面側の両側部における防漏性が向上するという利点も有する。さらに、側部シート71の内側端部72は、中央溝51,51よりも幅方向外方に位置しているため、一対の中央溝51,51に囲まれた部位の隆起と接触しにくくなっており、両側部における防漏効果の低下を起こさない点から好ましい。
また、本実施形態の生理用ナプキン1によれば、圧縮溝6が吸収性本体10の幅方向内方に凸に湾曲しているため、吸収性本体10の長手方向前後端ほど側部シート7の起立が高く形成され易く、身体の動き等によって生理用ナプキン1と身体との間に隙間が形成されにくい。
In thesanitary napkin 1 of the present embodiment, as described above, the portion surrounded by the pair ofcentral grooves 51 and 51 rises when worn. Due to the formation of the bulges, theside sheet 71 is more upright, and there is also an advantage that the leak-proof property at both sides of the absorbentmain body 10 on the skin contact surface side is improved. Further, since theinner end 72 of theside sheet 71 is positioned outward in the width direction with respect to thecentral grooves 51, 51, it is difficult to come into contact with the bulges of the portions surrounded by the pair ofcentral grooves 51, 51. It is preferable from the viewpoint that the leakage preventing effect is not lowered on both sides.
Moreover, according to thesanitary napkin 1 of this embodiment, since thecompressed groove 6 is curved so as to protrude inward in the width direction of the absorbentmain body 10, theside sheet 7 is closer to the longitudinal front and rear ends of the absorbentmain body 10. Is easy to be formed, and it is difficult to form a gap between thesanitary napkin 1 and the body due to movement of the body or the like.

次に、本発明の吸収性物品の第二実施形態の生理用ナプキンについて説明する。第二実施形態の生理用ナプキン1は、図6に示すように、一対の圧縮溝6,6が、幅方向外側に凸に湾曲している点で第一実施形態の生理用ナプキン1と異なる以外は、第一実施形態と同一である。  Next, the sanitary napkin of the second embodiment of the absorbent article of the present invention will be described. As shown in FIG. 6, thesanitary napkin 1 of the second embodiment is different from thesanitary napkin 1 of the first embodiment in that the pair ofcompressed grooves 6, 6 are convexly curved outward in the width direction. Other than the above, the second embodiment is the same as the first embodiment.

このように構成された第二実施形態の生理用ナプキン1によれば、第一実施形態と同様の効果が奏される他、一対の圧縮溝6,6が、幅方向外側に凸に湾曲しているため、吸収性本体10の中央部Bにおいて、側部シート7の起立が高く形成され易く、排泄領域(中央部B)での防漏効果が高められる。  According to thesanitary napkin 1 of the second embodiment configured as described above, the same effect as that of the first embodiment is achieved, and the pair ofcompressed grooves 6 and 6 are convexly curved outward in the width direction. Therefore, in the center part B of the absorptivemain body 10, theside sheet 7 is easily raised, and the leakage preventing effect in the excretion region (center part B) is enhanced.

本発明の吸収性物品は、前述した実施形態に制限されることなく、本発明の趣旨を逸脱しない限り適宜変更が可能である。
例えば、一対の圧縮溝6,6は、吸収性本体の長手方向に沿って直線状に設けられていてもよく、中央部Bにおいては直線状で、前方部Aの前端部及び後方部Cの後端部が幅方向内方又は幅方向外方に向けて延びている形状であってもよい。
本実施形態においては、前記前方溝54、前記中央溝51及び前記外側後方溝53がそれぞれ繋がって閉じた領域が形成されているが、上記各溝は繋がっていなくてもよく、その形状は本実施形態に示した形状に限られない。
The absorbent article of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention.
For example, the pair ofcompressed grooves 6 and 6 may be provided in a straight line along the longitudinal direction of the absorbent main body, and are straight in the central part B, and the front end part of the front part A and the rear part C. The rear end portion may have a shape extending inward in the width direction or outward in the width direction.
In the present embodiment, thefront groove 54, thecentral groove 51, and the outerrear groove 53 are connected to form a closed region. However, the grooves may not be connected, and the shape is It is not limited to the shape shown in the embodiment.

本実施形態においては、ウイング部8は、側部シート71及び裏面シート3を主体として構成されていたが、表面シート2及び裏面シート3から構成されていてもよく、また側部シート71、表面シート2及び裏面シート3の3層から構成されていてもよい。
本実施形態においては、サイド防漏部7を構成する側部シート71は、一層構造であったが、幅方向内側縁部で折り返されて2層構造となっていてもよい。
In the present embodiment, thewing portion 8 is mainly composed of theside sheet 71 and theback sheet 3, but may be composed of thetop sheet 2 and theback sheet 3. You may be comprised from 3 layers of the sheet |seat 2 and theback surface sheet 3. FIG.
In the present embodiment, theside sheet 71 constituting the side leak-proof portion 7 has a single-layer structure, but may be folded at the inner edge in the width direction to have a two-layer structure.

また、一対の圧縮溝6,6は、線状に限らず、ドット状エンボスやハート柄や花柄等の図柄が並んで形成され、ドット状エンボスや図柄の間が低くなって溝状になったものでも良い。このような場合、湾曲形状による効果は、幅方向内方側の形状によって奏される。  In addition, the pair ofcompressed grooves 6 and 6 is not limited to a linear shape, and is formed with a pattern such as a dot-shaped emboss, a heart pattern, or a floral pattern, and a space between the dot-shaped emboss and the pattern is lowered to form a groove. It may be good. In such a case, the effect of the curved shape is exhibited by the shape on the inner side in the width direction.

さらに、本発明の吸収性物品における吸収体は複数層からなるものであっても良くその複数層のうちの何れか一層のみが側方に延出し、その延出部に一対の圧縮溝6,6が形成されていても良い。
例えば、図8に示す生理用ナプキンの吸収体4は、上層41と下層42とが積層された構造を有しており、吸収性本体11の両側部に、上層41及び下層42の一方である下層42が、他方である上層41の両側縁部41a,41aそれぞれより幅方向外方に延出して形成された延出部43,43を有している。そして、それらの延出部43,43が位置する吸収性本体11の両側部に、側部シート71、表面シート2及び延出部43が圧縮されて形成された一対の圧縮溝6,6を有している。この場合においても、圧縮溝6,6の深さは、吸収性本体11の両側部における、吸収層11の厚み(表面シート2及び延出部43の合計厚みT4)の50〜100%、特に50〜100%であることが好ましい。図8に示す生理用ナプキンにおいて、下層42を上層41の両側縁部41a,41aそれぞれより外方に延出させて延出部43を形成するのに代えて、上層41を下層42の両側縁部より外方に延出させて延出部43を形成することもできる。図8に示す生理用ナプキンについて特に説明しない点は、第一又は第二実施形態の生理用ナプキンと同様である。
Furthermore, the absorbent body in the absorbent article of the present invention may be composed of a plurality of layers, and only one of the plurality of layers extends laterally, and a pair ofcompressed grooves 6, 6 may be formed.
For example, theabsorbent body 4 of the sanitary napkin shown in FIG. 8 has a structure in which an upper layer 41 and alower layer 42 are laminated, and is one of the upper layer 41 and thelower layer 42 on both sides of the absorbentmain body 11. Thelower layer 42 has extendedportions 43 and 43 that are formed to extend outward in the width direction from bothside edge portions 41 a and 41 a of the upper layer 41 that is the other side. And the side sheet |seat 71, thesurface sheet 2, and the pair ofcompression grooves 6 and 6 formed by compressing theextension part 43 are formed in the both sides of the absorptivemain body 11 in which thoseextension parts 43 and 43 are located. Have. Even in this case, the depth of thecompressed grooves 6 and 6 is 50 to 100% of the thickness of the absorbent layer 11 (total thickness T4 of thetopsheet 2 and the extended portion 43) on both sides of the absorbentmain body 11, particularly It is preferable that it is 50 to 100%. In the sanitary napkin shown in FIG. 8, instead of extending thelower layer 42 outwardly from bothside edge portions 41 a, 41 a of the upper layer 41 to form the extendedportion 43, the upper layer 41 is replaced with both side edges of thelower layer 42. The extendingportion 43 can also be formed by extending outward from the portion. The point which is not demonstrated especially about the sanitary napkin shown in FIG. 8 is the same as that of the sanitary napkin of 1st or 2nd embodiment.
