　本発明が解決しようとする課題は、以下の第１の課題～第３の課題のうちの少なくとも１つである。
　第１の課題は以下の通りである。特許文献１に記載のおむつは、前身頃と後身頃を対向側部で接合する接合部に近接する前身頃の部位に、前身頃を後身頃から切り離すための切断線を設けてあり、切断線に沿って切り離した後、後身頃の対向側から延出する締結片を介して前身頃と後身頃とを連結させることができる使い捨ておむつである。しかし、特許文献１のおむつは、着用者本人が自分で装着することを想定したおむつではなく、着用者に着用させることを前提とした仕様である。よって、仮にこのようなおむつを用いて着用者がトイレで座った状態、又は立った状態（中腰姿勢の状態）で、前身頃を構成する胴回り部材を自分で切断線に沿って切り離そうとすると、切断線に力が掛かりにくい場合や、胴回り部材が伸長して切りにくいことが考えられ、着用者が何度も持ち替えて破断を試みる手間等が発生する虞がある。また、切り離す際に必要以上の力を加えておむつの一部が破損してしまうことも考えられる。このように、テープ型としても使用可能なパンツ型吸収性物品を着用者が自分で装着する場合の装着しやすさについては、改良の余地がある。 The problem to be solved by the present invention is at least one of the following first to third problems.
The first issue is as follows. In the diaper described in Patent Document 1, a cutting line for separating the front body from the back body is provided at a portion of the front body adjacent to a joint where the front body and the back body are joined at opposing sides. The disposable diaper can connect the front body and the back body through the fastening piece extending from the opposite side of the back body after being separated along the front body. However, the diaper of Patent Literature 1 is designed on the premise that it is worn by the wearer, not by the wearer himself/herself. Therefore, if the wearer were to use such a diaper while sitting on the toilet or standing (half-legged posture), the waist member constituting the front body would be cut off along the cutting line by himself/herself. As a result, it may be difficult to apply force to the cutting line, or the waist member may be stretched and difficult to cut. Moreover, it is conceivable that a part of the diaper may be damaged by applying excessive force when separating it. As described above, there is room for improvement in terms of ease of putting on pants-type absorbent articles, which can also be used as tape-type absorbent articles, when the wearer himself/herself puts them on.
　本発明は、上記のような問題に鑑みてなされたものであって、その目的とするところは、テープ型としても使用可能であり、着用者による装着性の良いパンツ型吸収性物品を提供することにある。 The present invention has been made in view of the above problems, and its object is to provide a pants-type absorbent article that can be used as a tape type and is easy to wear by the wearer. That's what it is.
　第２の課題は以下の通りである。上記のようなテープ型としても使用可能なパンツ型吸収性物品を、生理用のショーツ型ナプキンや軽失禁用のおむつに適用したり、軽度の要介護者を着用対象者としたりする場合、着用者自身がパンツ型吸収性物品の着脱を行う。その場合、着用者は、破断誘導線で切り離した胴回り部材を片側の太腿に巻き付けつつ、胴回り部材の切り離し部分を太腿の前側まで引っ張ってきて、太腿の上でファスニングテープ（係合部材）を係合する着用方法が想定される。そうすることで、ファスニングテープを安定して係合できる。
　しかし、特許文献２の使い捨ておむつでは、吸収性コアを具備する下帯部材（吸収性本体）の幅方向両側縁よりも内側に、破断誘導線が形成されている。そのため、着用者はファスニングテープを係合する際に下帯部材を持つことになるが、下帯部材は、おむつの背丈方向（上下方向）に長く後側まで連続するため持ち難い。また、着用者は、ファスニングテープを係合する際に、下帯部材の部分を太腿の前側まで引っ張ってくる必要があり、装着が難しい。或いは、太腿の間で不安定な下帯部材の部分にファスニングテープを係合しなければならない。このように、テープ型としても使用可能なパンツ型吸収性物品を着用者が自分で装着する場合の装着しやすさについては、改良の余地がある。 The second issue is as follows. When applying the pants-type absorbent article that can also be used as a tape-type as described above to sanitary shorts-type napkins and diapers for light incontinence, or for those who require mild nursing care, The person himself/herself puts on and takes off the pants-type absorbent article. In that case, the wearer wraps the waist member separated by the tear guide line around one thigh, pulls the separated part of the waist member to the front side of the thigh, and places the fastening tape (engagement member) on the thigh. ) is envisioned. By doing so, the fastening tape can be stably engaged.
However, in the disposable diaper of Patent Literature 2, the rupture guide lines are formed on the inner side of both lateral side edges of the lower band member (absorbent main body) having the absorbent core. Therefore, the wearer holds the lower band member when engaging the fastening tape, but the lower band member is long in the back direction (vertical direction) of the diaper and continues to the rear side, making it difficult to hold. Moreover, when engaging the fastening tape, the wearer has to pull the lower band member to the front side of the thigh, which makes it difficult to wear. Alternatively, the fastening tape must engage the portion of the loincloth that is unstable between the thighs. As described above, there is room for improvement in terms of ease of putting on pants-type absorbent articles, which can also be used as tape-type absorbent articles, when the wearer himself/herself puts them on.
　本発明は、上記のような問題に鑑みてなされたものであって、その目的とするところは、テープ型としても使用可能であり、着用者による装着性の良いパンツ型吸収性物品を提供することにある。 The present invention has been made in view of the above problems, and its object is to provide a pants-type absorbent article that can be used as a tape type and is easy to wear by the wearer. That's what it is.
　第３の課題は以下の通りである。特許文献２には、上記のようなテープ型としても使用可能なパンツ型吸収性物品を、着用者がパンツ型の形態のまま着脱することで、高齢者等が自分でパンツを穿くリハビリ用に適していると記載されている。一方、パンツ型吸収性物品をテープ型にすることで、介助者が軽便におむつ交換できると記載されている。　
　しかし、テープ型としても使用可能なパンツ型吸収性物品を、着用者自身がテープ型にして装着することも可能である。その場合、着用者は、破断誘導線で切り離した胴回り部材を片側の太腿に巻き付けつつ、胴回り部材の切り離し部分を太腿の前側まで引っ張ってきて、太腿の上でファスニングテープ（係合部材）を係合する装着方法が想定される。そうすることで、ファスニングテープを安定して係合できる。
　ただし、着用者が、便器に座った状態、或いは、便器の近くにおいて中腰で立った状態で、片側の太腿にパンツ型吸収性物品を巻き付けた際に、太腿から垂れ下がったパンツ型吸収性物品の部位が便器に接触する恐れがある。そうすると、パンツ型吸収性物品の衛生状態が低下してしまう。 The third issue is as follows. Patent Document 2 describes a pants-type absorbent article that can be used as a tape type as described above, and is used for rehabilitation in which elderly people wear pants by themselves by putting on and taking off the pants-type absorbent article while the wearer remains in the form of pants-type. described as suitable. On the other hand, it is described that a caregiver can easily change diapers by making the pants-type absorbent article tape-shaped.
However, it is also possible for the wearer to wear the pants-type absorbent article, which can also be used as a tape-type, in the form of a tape-type. In that case, the wearer wraps the waist member separated by the tear guide line around one thigh, pulls the separated part of the waist member to the front side of the thigh, and places the fastening tape (engagement member) on the thigh. ) is envisioned. By doing so, the fastening tape can be stably engaged.
However, when the wearer wraps the pants-type absorbent article around one thigh while sitting on the toilet or standing half-assed near the toilet, the pants-type absorbent article hangs down from the thigh. Parts of the article may come into contact with the toilet bowl. As a result, the sanitary condition of the pants-type absorbent article is degraded.
　本発明は、上記のような問題に鑑みてなされたものであって、その目的とするところは、テープ型としても使用可能であり、着用者が自分で装着する場合にも衛生状態を良好に保って使用可能なパンツ型吸収性物品を提供することにある。 The present invention has been made in view of the above problems, and the object thereof is to provide a tape-type adhesive tape that can be used by the wearer himself/herself to maintain good sanitary conditions. To provide a pants-type absorbent article that can be kept and used.

　互いに交差する上下方向と左右方向と前後方向とを有し、吸収性本体と、前記前後方向に前記吸収性本体と重ねて配置された、前胴回り部及び後胴回り部を備え、前記左右方向に伸縮する胴回り部材と、前記前胴回り部の非肌側面に取り外し可能に係合する係合部材と、を有し、前記前胴回り部及び前記後胴回り部が接合された成人用のパンツ型吸収性物品であって、前記係合部材は、前記前胴回り部に接合されており、前記前胴回り部の前記左右方向の両側縁の間において、前記前胴回り部は、平面視において、前記係合部材と重なる重なり領域の少なくとも一部に、周囲よりも弾性係数が大きい高弾性部を有することを特徴とするパンツ型吸収性物品である。 At least the following matters will become apparent from the descriptions of this specification and the accompanying drawings.
It has a vertical direction, a horizontal direction, and a front-back direction that intersect with each other, and includes an absorbent body, and a front waistline portion and a rear waistline portion that are arranged to overlap the absorbent body in the front-back direction, An adult pants-type absorbent article having a stretchable waist member and an engaging member detachably engaged with the non-skin side of the front waist portion, wherein the front waist portion and the back waist portion are joined together. In the article, the engaging member is joined to the front waistline portion, and between both side edges of the front waistline portion in the left-right direction, the front waistline portion has the engagement member The underpants-type absorbent article is characterized in that at least a part of the overlapped region has a high-elasticity portion having a higher elastic modulus than the surrounding area.
　このようなパンツ型吸収性物品によれば、着用前に、一方の手で係合部材を持って左右方向の外側に広げ、前胴回り部のうち、広げる前に係合部材が重なっていた重なり領域に相当する部位を他方の手で持った状態で、互いに分離させるように左右方向外側へ引っ張る力を加えると、高弾性部は伸びにくいため、前胴回り部が該高弾性部で破れ易くなる。 According to such a pants-type absorbent article, before wearing, the engaging member is held with one hand and spread outward in the left-right direction. While holding the region corresponding to the region with the other hand, if a pulling force is applied to the outside in the left-right direction so as to separate them from each other, the high-elasticity portion is difficult to stretch, so the front waist portion is likely to tear at the high-elasticity portion. .
　かかるパンツ型吸収性物品であって、前記前胴回り部は、前記係合部材と前記左右方向に重なる領域の少なくとも一部において、前記上下方向の上側縁を含む上側領域、もしくは下側縁を含む下側領域に前記高弾性部を有することが望ましい。 In this pants-type absorbent article, the front waist portion includes an upper region including the upper edge in the vertical direction or a lower edge in at least a part of the region overlapping the engaging member in the left-right direction. It is desirable to have the high elastic portion in the lower region.
　このようなパンツ型吸収性物品によれば、前胴回り部の上側縁もしくは下側縁は、前胴回り部を破る動作が行われる際に引き裂きの開始点となる部位である。高弾性部は伸びにくく破れ易い部分であるため、上側縁を含む上側領域、又は下側縁を含む下側領域がそのような高弾性部を有することで、引き裂きの開始点が破れ易くなり、着用者は破く動作をスムーズに行うことができる。 According to such a pants-type absorbent article, the upper edge or the lower edge of the front waistline portion is the starting point of tearing when the front waistline portion is torn. Since the high-elasticity portion is a portion that is difficult to stretch and is easy to tear, the upper region including the upper edge or the lower region including the lower edge has such a high-elasticity portion, so that the starting point of tearing becomes easy to tear, The wearer can smoothly perform the tearing action.
　かかるパンツ型吸収性物品であって、自然状態において、前記前胴回り部と前記係合部材とが前記左右方向に重なる領域における前記前胴回り部の前記上下方向の長さの最小値は、８０ｍｍ以上１５０ｍｍ以下であることが望ましい。 In the pants-type absorbent article, in a natural state, the minimum length of the front waistline portion in the vertical direction in the region where the front waistline portion and the engaging member overlap in the left-right direction is 80 mm or more. 150 mm or less is desirable.

　吸収性本体１０は、図２に示すように、その長手方向がナプキン１の上下方向に沿った平面視略長方形状である。そして、図３に示すように、吸収性本体１０は、長手方向（上下方向）に沿った吸収性コア１１と、吸収性コア１１よりも肌側に配置されたトップシート１２と、吸収性コア１１よりも非肌側に配置されたバックシート１３と、を有している。但し、吸収性本体１０が、これ以外のシート部材を備えていても良い。例えば、トップシート１２と吸収性コア１１との厚さ方向の間に、セカンドシート（不図示）を備えていてもよい。 (Absorptive main body 10)
As shown in FIG. 2, the absorbent main body 10 has a substantially rectangular shape in plan view with its longitudinal direction along the vertical direction of the napkin 1 . As shown in FIG. 3, the absorbent main body 10 includes an absorbent core 11 along the longitudinal direction (vertical direction), a top sheet 12 arranged closer to the skin than the absorbent core 11, and an absorbent core 11. and a back sheet 13 arranged on the non-skin side of 11 . However, the absorbent main body 10 may be provided with sheet members other than this. For example, a second sheet (not shown) may be provided between the top sheet 12 and the absorbent core 11 in the thickness direction.
　吸収性コア１１は、経血等の液体を吸収して保持する部材であり、例えば高吸収性ポリマー（ＳＡＰ）が混入したパルプ繊維等の液体吸収性繊維により形成される。なお、吸収性コア１１は、ティッシュペーパーや不織布等の液透過性のシート部材（コアラップシート）によって、外周面が覆われていても良い。 The absorbent core 11 is a member that absorbs and retains liquid such as menstrual blood, and is formed of, for example, liquid-absorbent fibers such as pulp fibers mixed with superabsorbent polymer (SAP). The absorbent core 11 may be covered with a liquid-permeable sheet member (core wrap sheet) such as tissue paper or nonwoven fabric.
　トップシート１２は、着用時において着用者の肌に接触し得る液透過性のシート部材であり、例えば親水性のエアスルー不織布やスパンボンド不織布等により形成される。 The top sheet 12 is a liquid-permeable sheet member that can come into contact with the wearer's skin when worn, and is made of, for example, a hydrophilic air-through nonwoven fabric or spunbond nonwoven fabric.
　バックシート１３は、吸収性コア１１に吸収された経血等の液体が外部に漏れ出すことを抑制するための液不透過性シート１３ａと、液不透過性シート１３ａの非肌側に配置された疎水性シート１３ｂと、を備えた二層構造で形成されている。液不透過性シート１３ａとしては、例えば樹脂フィルム等が用いられ、疎水性シート１３ｂとしては、例えば柔軟性を有する不織布等が用いられる。但し、疎水性シート１３ｂは必ずしも設けられていなくても良く、液不透過性シート１３ａのみによってバックシート１３が構成されていても良い。 The back sheet 13 is arranged on the non-skin side of the liquid-impermeable sheet 13a for suppressing leakage of liquid such as menstrual blood absorbed by the absorbent core 11 to the outside, and the liquid-impermeable sheet 13a. and a hydrophobic sheet 13b. For example, a resin film or the like is used as the liquid-impermeable sheet 13a, and a flexible non-woven fabric or the like is used as the hydrophobic sheet 13b. However, the hydrophobic sheet 13b may not necessarily be provided, and the back sheet 13 may be composed only of the liquid-impermeable sheet 13a.
　また、吸収性本体１０の左右方向両側に不図示の防漏壁部が設けられていても良い。防漏壁部は、所謂立体ギャザーに相当する部位であり、ナプキン１の着用時には、該防漏壁部が、吸収性本体１０の左右方向の両側から着用者の肌側に起立することにより、経血等の排泄液が吸収性本体１０の外側に漏出することを抑制する。 In addition, leak-proof walls (not shown) may be provided on both sides in the left-right direction of the absorbent main body 10 . The leak-proof wall portion is a portion corresponding to a so-called three-dimensional gather. It suppresses leakage of excretory liquid such as menstrual blood to the outside of the absorbent main body 10 .
　また、吸収性本体１０には、その長手方向に沿って伸縮する吸収体弾性部材５０が複数設けられている。吸収体弾性部材５０は、例えば糸ゴムによって構成され、本実施形態では、液不透過性シート１３ａと疎水性シート１３ｂとの間に、長手方向に伸長した状態で配置されている（図３）。本実施形態のナプキン１では、左右方向に所定の間隔を空けて５本の吸収体弾性部材５０が設けられている（図２参照）。吸収体弾性部材５０の伸長倍率は１．４～３．３倍程度とすることが好ましい。なお、伸長倍率は、伸長状態の弾性部材の長さを自然状態の弾性部材の長さで除した値で表される。吸収体弾性部材５０の伸長倍率をある程度強い倍率に設定しておくとよい。そうすることで、後述の図８に示すように、吸収性本体１０が着用者の肌側に持ち上げられ、吸収性本体１０が着用者の股下部（膣口）に密着しやすくなり、排泄液の漏れを抑制できる。 In addition, the absorbent main body 10 is provided with a plurality of absorbent elastic members 50 that expand and contract along its longitudinal direction. The absorber elastic member 50 is made of, for example, rubber thread, and in this embodiment, is arranged in a longitudinally stretched state between the liquid-impermeable sheet 13a and the hydrophobic sheet 13b (FIG. 3). . In the napkin 1 of this embodiment, five absorbent body elastic members 50 are provided at predetermined intervals in the left-right direction (see FIG. 2). The expansion ratio of the absorbent elastic member 50 is preferably about 1.4 to 3.3 times. The extension ratio is expressed by a value obtained by dividing the length of the elastic member in the stretched state by the length of the elastic member in the natural state. It is preferable to set the extension ratio of the absorbent body elastic member 50 to a relatively large ratio. By doing so, as shown in FIG. 8 to be described later, the absorbent main body 10 is lifted toward the wearer's skin side, and the absorbent main body 10 is easily brought into close contact with the wearer's crotch (vaginal opening), and excretory fluid is discharged. leakage can be suppressed.
　（胴回り部材２０）
　胴回り部材２０は、複数のシート部材によって構成された外装体であり、少なくとも非肌側シート２１と、肌側シート２２，２３とを備えている（図３参照）。また、以下の説明では、胴回り部材２０のうち、長手方向において、中央位置ＣＬよりも前側（腹側）の部分を前胴回り部２０ｆ、中央位置ＣＬよりも後側（背側）の部分を後胴回り部２０ｂとも呼ぶ。前胴回り部２０ｆは、ナプキン１の着用時に、着用者の身体の腹側に当たる部位である。また、後胴回り部２０ｂは、ナプキン１の着用時に、着用者の身体の背側に当たる部位である。 (Waist circumference member 20)
The waist member 20 is an outer body composed of a plurality of sheet members, and includes at least a non-skin-side sheet 21 and skin-side sheets 22 and 23 (see FIG. 3). Further, in the following description, of the waist member 20, in the longitudinal direction, the front waist portion 20f is the portion on the front side (abdominal side) of the central position CL, and the rear side (dorsal side) of the center position CL is the rear waist portion 20f. It is also called a waist portion 20b. The front waist portion 20f is a portion that contacts the ventral side of the wearer's body when the napkin 1 is worn. Further, the rear waist portion 20b is a portion that comes into contact with the back side of the wearer's body when the napkin 1 is worn.
　非肌側シート２１は、ナプキン１の最も非肌側に配置される非伸縮性のシート部材であり、例えばスパンボンド不織布やＳＭＳ不織布等により形成される。本実施形態の非肌側シート２１は、図２で示されるように、縦方向の中央部において左右方向内側に向かって括れた形状を有している。 The non-skin-side sheet 21 is a non-stretchable sheet member arranged on the most non-skin side of the napkin 1, and is formed of, for example, spunbond nonwoven fabric or SMS nonwoven fabric. As shown in FIG. 2, the non-skin-side sheet 21 of the present embodiment has a shape that narrows inward in the left-right direction at the central portion in the longitudinal direction.
　肌側シート２２は、長手方向の前側（腹側）において非肌側シート２１の肌側に積層された伸縮性を有するシート部材である。肌側シート２２は、例えば、伸縮性不織布により形成される。「伸縮性不織布」とは、伸縮性を有する伸縮性繊維、及び伸縮性繊維よりも収縮性の低い伸長性繊維を含み、ギア延伸等の適宜な延伸処理が施された不織布である。
本実施形態の肌側シート２２は、伸縮性繊維として、弾性を有する熱可塑性エラストマーの一種であるポリウレタン系エラストマーの繊維を用いることが可能であり、伸長性繊維として、非弾性を有する熱可塑性樹脂の一種であるポリオレフィン系樹脂のポリプロピレン（ＰＰ）の繊維を用いることが可能である。 The skin-side sheet 22 is a stretchable sheet member laminated on the skin side of the non-skin-side sheet 21 on the front side (abdominal side) in the longitudinal direction. The skin-side sheet 22 is made of stretchable nonwoven fabric, for example. The term “stretchable nonwoven fabric” refers to a nonwoven fabric that contains stretchable fibers and extensible fibers with lower contractility than the stretchable fibers and that has been subjected to an appropriate stretching treatment such as gear stretching.
The skin-side sheet 22 of the present embodiment can use polyurethane-based elastomer fibers, which are a type of elastic thermoplastic elastomer, as stretchable fibers, and non-elastic thermoplastic resin as stretchable fibers. It is possible to use fibers of polypropylene (PP), which is a type of polyolefin resin.
　肌側シート２２は、点在する複数のシート接合部（不図示）によって非肌側シート２１と接合されており、これにより、前胴回り部２０ｆに、少なくとも左右方向に沿った伸縮性が付与される。本実施形態において、シート接合部は、超音波溶着等の公知の接合手段を用いて形成される。 The skin-side sheet 22 is joined to the non-skin-side sheet 21 by a plurality of scattered sheet joining portions (not shown), whereby the front waist portion 20f is given elasticity at least along the left-right direction. be. In this embodiment, the sheet joints are formed using known joining means such as ultrasonic welding.
　肌側シート２３は、長手方向の後側（背側）において非肌側シート２１の肌側に積層された伸縮性を有するシート部材である。肌側シート２３は、肌側シート２２と同様の構成を有している。すなわち、肌側シート２３は、伸縮性不織布によって形成され、点在する複数のシート接合部（不図示）によって非肌側シート２１と接合されている。これにより、後胴回り部２０ｂに、少なくとも左右方向の伸縮性が付与される。 The skin-side sheet 23 is a stretchable sheet member laminated on the skin side of the non-skin-side sheet 21 on the rear side (dorsal side) in the longitudinal direction. The skin-side sheet 23 has the same configuration as the skin-side sheet 22 . That is, the skin-side sheet 23 is formed of a stretchable nonwoven fabric, and is joined to the non-skin-side sheet 21 by a plurality of scattered sheet joining portions (not shown). As a result, the rear waist portion 20b is provided with stretchability in at least the left-right direction.
　なお、胴回り部材２０を構成するシート部材として、非肌側シート２１及び肌側シート２２，２３以外の他のシート部材が設けられていても良い。例えば、胴回り部材２０は、伸縮性の肌側シート２２，２３のさらに肌側に、非伸縮性不織布が配置され、伸縮不織布が非伸縮不織布によって挟まれた３層構造であっても良い。また、３層構造である場合は、肌側シート２２，２３が伸縮フィルムであってもよい。また、非肌側シート２１が前側と後側とで分離されていてもよい。その場合、前側の非肌側シート２１と後側の非肌側シート２１の間で、バックシート１３の非肌側面が露出していてもよいし、前側の非肌側シート２１と後側の非肌側シート２１を繋ぐ別体の非肌側シートが股下部に設けられていてもよい。 Note that sheet members other than the non-skin-side sheet 21 and the skin- side sheets 22 and 23 may be provided as sheet members constituting the waist member 20 . For example, the waist member 20 may have a three-layer structure in which a non-stretchable non-woven fabric is arranged on the skin side of the stretchable skin- side sheets 22 and 23, and the stretchable non-woven fabric is sandwiched between the non-stretchable non-stretchable non-woven fabrics. In the case of a three-layer structure, the skin- side sheets 22 and 23 may be elastic films. Moreover, the non-skin side sheet 21 may be separated into the front side and the back side. In that case, the non-skin side of the back sheet 13 may be exposed between the front non-skin side sheet 21 and the rear non-skin side sheet 21, or the front non-skin side sheet 21 and the rear non-skin side sheet 21 may be exposed. A separate non-skin-side sheet connecting the non-skin-side sheet 21 may be provided at the crotch portion.
　（タブ３０）
　ナプキン１は、胴回り部材２０の左右方向の両側部において、前胴回り部２０ｆの非肌側面に取り外し可能に係合する一対のタブ３０（係合部材）を有する。なお、図２では、肌側から見たナプキン１において、前胴回り部２０ｆの非肌側面に係合されているタブ３０を仮想的に示している。タブ３０は、基材シート３１と、係合部３２と、を有している。基材シート３１は、不織布等からなるシート部材である。基材シート３１の左右方向の外側端部が、サイド接合部４０によって胴回り部材２０に接合されている。つまり、サイド接合部４０によって、前胴回り部２０ｆと、後胴回り部２０ｂと、タブ３０とが一体的に接合されている。但し、サイド接合部４０とは異なる部位にてタブ３０が胴回り部材２０に接合されていてもよい。 (Tab 30)
The napkin 1 has a pair of tabs 30 (engagement members) detachably engaged with the non-skin side surfaces of the front waistline portion 20f on both sides of the waistline member 20 in the left-right direction. In addition, in FIG. 2, in the napkin 1 seen from the skin side, the tab 30 engaged with the non-skin side surface of the front waist part 20f is imaginarily shown. The tab 30 has a base sheet 31 and an engaging portion 32 . The base sheet 31 is a sheet member made of nonwoven fabric or the like. The laterally outer edge of the base sheet 31 is joined to the waistline member 20 by the side joints 40 . That is, the front waistline portion 20f, the rear waistline portion 20b, and the tab 30 are integrally joined by the side joint portion 40. As shown in FIG. However, the tab 30 may be joined to the waist member 20 at a location different from the side joints 40 .
　係合部３２は、左右方向においてサイド接合部４０で接合されている側とは反対側の基材シート３１の端部に設けられている。また、係合部３２は、基材シート３１の肌側面に設けられ、前胴回り部２０ｆの非肌側面と対向し、前胴回り部２０ｆの非肌側面に取り外し可能に係合する部材である。係合部３２としては、非肌側シート２１を構成する繊維に引っ掛かる突起（フック部材）を備えた面ファスナーの雄部材を例示できる。なお、非肌側シート２１の非肌側面に係合部３２が係合しやすい部材（例えば面ファスナーの雌部材）が設けられていてもよい。 The engaging portion 32 is provided at the end portion of the base sheet 31 opposite to the side joined by the side joint portion 40 in the left-right direction. The engaging portion 32 is provided on the skin side of the base sheet 31, faces the non-skin side of the front waist portion 20f, and is a member that removably engages the non-skin side of the front waist portion 20f. As the engaging portion 32, a male member of a hook-and-loop fastener provided with projections (hook members) that are caught by the fibers forming the non-skin side sheet 21 can be exemplified. The non-skin side surface of the non-skin side sheet 21 may be provided with a member (for example, a female member of a hook-and-loop fastener) with which the engaging portion 32 is easily engaged.
　＜ナプキン１の装着方法について＞
　図４Ａ及び図４Ｂは、ナプキン１を胴回り開口１ａ側から見た断面模式図である。図４Ａはパンツ型で使用されるナプキン１の図であり、図４Ｂはテープ型で使用されるナプキン１の図である。図５は、切り取り線２５に沿って前胴回り部２０ｆを後胴回り部２０ｂから分離させた状態のナプキン１の展開平面図である。 <How to attach napkin 1>
4A and 4B are schematic cross-sectional views of the napkin 1 viewed from the side of the waist opening 1a. FIG. 4A is a diagram of a napkin 1 used in a pants type, and FIG. 4B is a diagram of a napkin 1 used in a tape type. FIG. 5 is a developed plan view of the napkin 1 with the front waistline portion 20f separated from the rear waistline portion 20b along the perforation line 25. FIG.
　ナプキン１は、パッケージから取り出された初期状態においては、前胴回り部２０ｆ及び後胴回り部２０ｂが環状で繋がれたパンツ型（図４Ａ）である。そのため、着用者は、ナプキン１をパンツ型のままで着脱することが可能である。 When the napkin 1 is taken out of the package, in the initial state, it is a pants type (Fig. 4A) in which the front waistline portion 20f and the rear waistline portion 20b are connected in a loop. Therefore, the wearer can put on and take off the napkin 1 while it is in the form of pants.
　また、ナプキン１の前胴回り部２０ｆは、左右方向の両側の端部において、上下方向に長さを有する切り取り線２５を有する。そのため、切り取り線２５に沿って前胴回り部２０ｆを上下方向に破り、前胴回り部２０ｆの一部を後胴回り部２０ｂから分離できる。分離後のナプキン１は、図５に示すように、後胴回り部２０ｂから一対のタブ３０が左右方向の両外側に延出したテープ型となる。そのため、着用者は、ナプキン１をテープ型にして着脱することも可能である。 In addition, the front waist portion 20f of the napkin 1 has perforations 25 having lengths in the vertical direction at both ends in the left-right direction. Therefore, the front waistline portion 20f can be vertically broken along the perforation line 25 to separate a part of the front waistline portion 20f from the rear waistline portion 20b. As shown in FIG. 5, the napkin 1 after separation has a tape shape in which a pair of tabs 30 extend outward in the left-right direction from the rear waist portion 20b. Therefore, the wearer can put on and take off the napkin 1 in the form of a tape.
　以下の説明では、左右方向の少なくとも片側が後胴回り部２０ｂから分離された前胴回り部２０ｆの部位を「腹側当接部２０ｆＡ」とも呼ぶ。また、後胴回り部２０ｂから分離されずに、サイド接合部４０側に残っている前胴回り部２０ｆの部位を「非分離部２０ｆＢ」とも呼ぶ。 In the following description, the portion of the front waistline portion 20f separated from the rear waistline portion 20b on at least one side in the left-right direction is also referred to as the "abdominal contact portion 20fA". A portion of the front waistline portion 20f that remains on the side joint portion 40 side without being separated from the rear waistline portion 20b is also referred to as a "non-separated portion 20fB".
　図６Ａ～図６Ｃ、及び、図７Ａ～図７Ｄは、着用者がナプキン１を装着する方法の一例を説明する図である。ナプキン１の着用対象者は一般にナプキン１を自分で着脱する。また、着用者は、図６Ｃ等に示すように不図示の便器等に座った状態、又は立った状態（中腰姿勢の状態）で、ナプキン１を着脱する。 6A to 6C and 7A to 7D are diagrams explaining an example of how the wearer wears the napkin 1. FIG. A person who wears the napkin 1 generally puts on and takes off the napkin 1 by himself/herself. Also, the wearer attaches and detaches the napkin 1 while sitting on a toilet or the like (not shown) as shown in FIG.
　次に、ナプキン１をテープ型で装着する方法の一例を説明する。着用者は、まず、図６Ａに示すように、パンツ型のナプキン１の左右方向の一方側のタブ３０を左右方向の外側（一方側）に開き、切り取り線２５を露出させる。次に、着用者は、図６Ｂに示すように、切り取り線２５に沿って前胴回り部２０ｆの左右方向の一方側の端部を上下方向に破り、前胴回り部２０ｆの一部である腹側当接部２０ｆＡを後胴回り部２０ｂから分離する。
次に、着用者は、図６Ｃに示すように、胴回り部材２０の切り離し部分を太腿の前側まで引っ張ってきて、胴回り部材２０を片側の太腿に巻き付ける。そして、図７Ａに示すように、太腿の上で前胴回り部２０ｆ（腹側当接部２０ｆＡ）の非肌側面にタブ３０（係合部３２）を係合する。 Next, an example of a method of attaching the napkin 1 with a tape type will be described. First, as shown in FIG. 6A, the wearer opens the tab 30 on one side in the left-right direction of the pants-type napkin 1 to the outside (one side) in the left-right direction to expose the perforation line 25 . Next, as shown in FIG. 6B, the wearer vertically breaks one end of the front waist portion 20f in the left-right direction along the perforation line 25, and cuts the abdomen, which is a part of the front waist portion 20f. The contact portion 20fA is separated from the rear waist portion 20b.
Next, the wearer pulls the cut-off portion of the waist member 20 to the front side of the thigh and wraps the waist member 20 around one thigh, as shown in FIG. 6C. Then, as shown in FIG. 7A, the tab 30 (engagement portion 32) is engaged with the non-skin side surface of the front waist portion 20f (abdominal contact portion 20fA) on the thigh.
　図７Ａの状態では、サイド接合部４０が太腿の上に位置し、吸収性本体１０（吸収性コア１１）が太腿の間で垂れ下がっている。そのため、着用者は、ナプキン１を太腿の周方向（図７Ａの右太腿上に示す方向）に沿って回転する。そうして、図７Ｂに示すように、サイド接合部４０を自分の脇に位置合わせし、吸収性本体１０を太腿の間に引き上げる。 In the state of FIG. 7A, the side joints 40 are positioned on the thighs, and the absorbent main body 10 (absorbent core 11) hangs down between the thighs. Therefore, the wearer rotates the napkin 1 along the circumferential direction of the thigh (the direction shown on the right thigh in FIG. 7A). Then, as shown in FIG. 7B, the side joints 40 are aligned with one's armpits and the absorbent body 10 is pulled up between the thighs.
　次に、図７Ｃに示すように、着用者は、反対側のタブ３０を左右方向の外側に開き、切り取り線２５に沿って前胴回り部２０ｆの左右方向の他方側の端部を上下方向に破り、前胴回り部２０ｆの一部である腹側当接部２０ｆＡを後胴回り部２０ｂから分離する。それと共に、着用者は、ナプキン１が巻き付けられている太腿側に傾いている吸収性本体１０の傾きを、太腿が延びる方向に沿うように直しながら、太腿の間（着用者の幅方向の中心）に吸収性本体１０を位置合わせする。そして、図７Ｄに示すように、胴回り部材２０の切り離し部分を太腿の前側まで引っ張ってきて、反対側の太腿にも胴回り部材２０を巻き付けて、太腿の上で前胴回り部２０ｆの非肌側面にタブ３０を係合する。 Next, as shown in FIG. 7C, the wearer opens the tab 30 on the opposite side to the outside in the left-right direction, and moves the other end of the front waist portion 20f in the left-right direction along the perforation line 25 in the up-down direction. It is broken to separate the ventral contact portion 20fA, which is a part of the front waistline portion 20f, from the rear waistline portion 20b. At the same time, the wearer corrects the inclination of the absorbent main body 10, which is inclined toward the thigh side around which the napkin 1 is wrapped, so as to follow the direction in which the thigh extends. direction center). Then, as shown in FIG. 7D, the cut-off portion of the waist member 20 is pulled to the front side of the thigh, the waist member 20 is wrapped around the opposite thigh, and the front waist member 20f is placed on the thigh. A tab 30 is engaged on the skin side.
　そうすることで、図４Ｂに示すように、切り取り線２５で分離された前胴回り部２０ｆの腹側当接部２０ｆＡは、一対のタブ３０によって後胴回り部２０ｂと再び環状につながった状態となる。また、着用者の両太腿がナプキン１の一対の脚回り開口１ｂを通った状態となる。最後に、着用者はナプキン１を引き上げて、ナプキン１の装着が完了する。 By doing so, as shown in FIG. 4B, the ventral contact portion 20fA of the front waistline portion 20f separated by the perforation line 25 is again annularly connected to the rear waistline portion 20b by the pair of tabs 30. . Also, both thighs of the wearer pass through the pair of leg openings 1 b of the napkin 1 . Finally, the wearer pulls up the napkin 1 to complete wearing of the napkin 1 .
　このように、前胴回り部２０ｆの非肌側面に取り外し可能に係合するタブ３０を有することで、着用者は、ナプキン１をテープ型にして使用する場合に、自分の前側においてタブ３０を視認しながら前胴回り部２０ｆにタブ３０を係合できる。よって、着用者が自分でナプキン１を装着する場合の装着性が良い。また、ナプキン１を取り外す場合にも、着用者は自分の前側においてタブ３０を視認しながら前胴回り部２０ｆからタブ３０を取り外すことができる。 By having the tab 30 detachably engaged with the non-skin side of the front waist portion 20f in this manner, the wearer can visually recognize the tab 30 on the front side of the wearer when using the napkin 1 in a tape shape. The tab 30 can be engaged with the front waist portion 20f while moving. Therefore, the wearability is good when the wearer wears the napkin 1 by himself/herself. Also, when removing the napkin 1, the wearer can remove the tab 30 from the front waist portion 20f while visually recognizing the tab 30 on the front side of the wearer.
　なお、パンツ型のままでナプキン１を装着した場合、パンツ型のままでナプキン１を脱ぐことも可能であるが、切り取り線２５にて前胴回り部２０ｆを破いてナプキン１を取り外すことも可能である。逆に、テープ型の状態にしてナプキン１を装着した場合に、タブ３０を取り外すことなくナプキン１を脱ぐことも可能である。 In addition, when the napkin 1 is attached while still in the pants shape, it is possible to take off the napkin 1 in the pants shape, but it is also possible to remove the napkin 1 by tearing the front waist portion 20 f along the cutting line 25 . be. Conversely, when the napkin 1 is attached in a tape-type state, the napkin 1 can be taken off without removing the tab 30 .
　本実施形態のナプキン１のように、パンツ型（ショーツ型）ナプキンをテープ型として自分で装着できる仕様にするために、着用者自身が胴回り部材の一部を破いて身体に配置した後、タブを胴回り部に固定する場合、胴回り部材が破きにくいと、着用者が何度も持ち替えて破断を試みる手間が発生する虞や、必要以上の力を加えてナプキンの一部が破損してしまう虞等がある。 Like the napkin 1 of this embodiment, in order to make the pants type (shorts type) napkin as a tape type so that it can be worn by the wearer himself, after tearing a part of the waist member and placing it on the body, the tab When fixing to the waist part, if the waist member is difficult to break, there is a risk that the wearer will have to change the grip many times to try to break it, and a part of the napkin will be damaged by applying more force than necessary. There are fears, etc.
　この点につき、本実施形態のナプキン１は、次のような構成を有する。図８及び図９は、パンツ型のナプキン１を前側から見た正面図である。まず、図２及び図５に示すように、前胴回り部２０ｆ及び後胴回り部２０ｂは、それぞれ、左右方向に伸縮する肌側シート２２，２３、及び、胴回り弾性部材２４を有し、左右方向に伸縮性を有する。つまり、前胴回り部２０ｆ及び後胴回り部２０ｂの少なくとも左右方向の中央部は、左右方向に伸縮する伸縮する領域（後述する低弾性部２０ＥＡ）によって左右方向に伸縮し、ナプキン１が着用者の胴回りにフィットする。さらに、図８（及び図２，図５）に示すように、前胴回り部２０ｆは、左右方向の両端部に、周囲よりも弾性係数が大きい高弾性部２０ＮＡを有している。本実施形態における高弾性部２０ＮＡは、図９に示すように、前胴回り部２０ｆの左右方向の両側において、側縁２０ｆｅから係合部３２の少なくとも一部と重なる位置まで、且つ、上下方向において前胴回り部２０ｆの上側縁２０ｆｕｐから下側縁２０ｆｄｗまで設けられている。なお、上述の範囲に限らず、高弾性部２０ＮＡは、前胴回り部２０ｆの左右方向の両側縁２０ｆｅ、２０ｆｅの間において、平面視において前胴回り部２０ｆとタブ３０とが重なる重なり領域２０ｆｃ（図８参照）の少なくとも一部に設けられていればよい。 In this regard, the napkin 1 of this embodiment has the following configuration. 8 and 9 are front views of the underpants-type napkin 1 viewed from the front side. First, as shown in FIGS. 2 and 5, the front waistline portion 20f and the rear waistline portion 20b each have skin- side sheets 22 and 23 that stretch in the left-right direction and a waist elastic member 24 that stretches in the left-right direction. It has elasticity. That is, at least the central portion in the left-right direction of the front waist portion 20f and the rear waist portion 20b is stretched in the left-right direction by a stretchable region (a low elastic portion 20EA described later) that stretches in the left-right direction, and the napkin 1 fits around the wearer's waist. to fit. Further, as shown in FIG. 8 (and FIGS. 2 and 5), the front waist portion 20f has high elastic portions 20NA having a higher elastic modulus than the surroundings at both ends in the left-right direction. As shown in FIG. 9, the high-elasticity portion 20NA in the present embodiment extends from the side edge 20fe to a position overlapping at least a portion of the engaging portion 32 on both sides in the left-right direction of the front waist portion 20f, and in the vertical direction. It is provided from the upper edge 20fup to the lower edge 20fdw of the front waist portion 20f. Note that the high-elasticity portion 20NA is not limited to the above-described range, and is formed between the lateral side edges 20fe, 20fe of the front waistline portion 20f in an overlapping region 20fc (FIG. 8)).
　前胴回り部２０ｆの弾性係数は、例えば、自然状態で前胴回り部２０ｆから高弾性部２０ＮＡと、左右の高弾性部２０ＮＡ間の部分とをそれぞれ切り出してサンプルを作製し、引張試験機（例えば（株）島津製作所製のオートグラフ型引張試験機ＡＧ－１ＫＮ１等）を用いて引張試験を行い、引張弾性率を算出することで求めてもよい。 The modulus of elasticity of the front waist portion 20f is determined, for example, by cutting out the high-elasticity portion 20NA from the front waist portion 20f and the portion between the left and right high-elasticity portions 20NA in a natural state, and preparing samples using a tensile tester (for example, ( It may be determined by performing a tensile test using an autograph type tensile tester AG-1KN1 manufactured by Shimadzu Corporation, and calculating the tensile modulus.
　本実施形態では、前胴回り部２０ｆの高弾性部２０ＮＡは、前胴回り部２０ｆを構成する肌側シート２２と非肌側シート２１との接合を超音波接合によって行う際、点在する複数のシート接合部（不図示）の接合パターンを高弾性部２０ＮＡと後述する低弾性部２０ＥＡとで異なるようにすることで形成される。具体的に、例えば、高弾性部２０ＮＡにおけるシート接合部の数を多くすることで、肌側シート２２の伸縮性を弱めて高弾性部２０ＮＡを形成してもよい。 In the present embodiment, the high-elasticity portion 20NA of the front waist portion 20f includes a plurality of scattered sheets when the skin-side sheet 22 and the non-skin-side sheet 21 forming the front waist portion 20f are joined by ultrasonic bonding. It is formed by making the bonding pattern of the bonding portion (not shown) different between the high-elasticity portion 20NA and the low-elasticity portion 20EA, which will be described later. Specifically, for example, by increasing the number of sheet joints in the high-elasticity portion 20NA, the stretchability of the skin-side sheet 22 may be weakened to form the high-elasticity portion 20NA.
　なお、超音波接合に限らず、ヒートシール等の別の接合方法を用いてもよい。また、高弾性部２０ＮＡは、別の方法によって形成されてもよく、一例として、高弾性部２０ＮＡを形成する部分に、不織布等の伸縮性を有さない別のもう一つのシート部材を貼り付け、高弾性部２０ＮＡ部分の肌側シート２２を伸縮しにくくさせることで、弾性係数が大きい高弾性部２０ＮＡを形成してもよい。また、例えば、前胴回り部２０ｆを構成する資材として伸縮性不織布を用いずに、伸縮しない２枚の不織布等のシート部材によって前胴回り部２０ｆを構成し、当該２枚のシート部材の間に糸ゴムからなる左右方向に伸縮する弾性部材を配置し、高弾性部２０ＮＡと低弾性部２０ＥＡとにおいて糸ゴムの太さを変えることによって、所望の弾性係数を有する高弾性部２０ＮＡを形成してもよい。 It should be noted that not only ultrasonic bonding but also other bonding methods such as heat sealing may be used. Alternatively, the highly elastic portion 20NA may be formed by another method. As an example, another non-stretchable sheet member such as a non-woven fabric is attached to the portion forming the highly elastic portion 20NA. By making the skin-side sheet 22 of the high-elasticity portion 20NA difficult to stretch, the high-elasticity portion 20NA having a large elastic modulus may be formed. Alternatively, for example, instead of using a stretchable nonwoven fabric as a material for forming the front waistline portion 20f, the front waistline portion 20f is formed of two non-stretchable sheet members such as nonwoven fabric, and a thread is inserted between the two sheet members. A high elastic portion 20NA having a desired elastic modulus may be formed by arranging an elastic member made of rubber that expands and contracts in the horizontal direction and changing the thickness of the thread rubber between the high elastic portion 20NA and the low elastic portion 20EA. good.
　ナプキン１をテープ型として使用する場合、着用者は、まず、図６Ｂに示すように、左右方向の外側に広げたタブ３０を一方の手で持ち、前胴回り部２０ｆのうち、図８に示すタブ３０と重なる重なり領域２０ｆｃに相当する部位を他方の手で持ち、互いに分離させるように左右方向外側へ引っ張る力を加える。前胴回り部２０ｆの高弾性部２０ＮＡは、変形しにくい（伸びにくい）性質を有しているため、前胴回り部２０ｆは、高弾性部２０ＮＡの部分で破れ易い。着用者が自分で装着する手順の最初の段階で前胴回り部２０ｆを容易に破ることができることにより、装着性が向上し、スムーズに次の手順に進むことができる。また、反対側のタブ３０を破る際（図７Ｃに示す動作の際）にも、同様に、着用者は、前胴回り部２０ｆを高弾性部２０ＮＡの部分で破り易く、座った状態での装着性も向上する。 When using the napkin 1 as a tape type, the wearer first holds the tab 30 spread outward in the left-right direction with one hand as shown in FIG. A portion corresponding to the overlapping region 20fc that overlaps with the tab 30 is held with the other hand, and a pulling force is applied laterally outward so as to separate them from each other. Since the high-elasticity portion 20NA of the front waistline portion 20f is resistant to deformation (stretching), the front waistline portion 20f is easily broken at the high-elasticity portion 20NA. Since the wearer can easily tear the front waist part 20f at the first stage of the procedure of wearing by himself/herself, the wearability is improved, and the next procedure can be proceeded smoothly. Similarly, when breaking the tab 30 on the opposite side (during the action shown in FIG. 7C), the wearer can easily break the front waist portion 20f at the high elastic portion 20NA and can wear it while sitting. sexuality is also improved.
　また、本実施形態における前胴回り部２０ｆの高弾性部２０ＮＡは、上下方向において、上側縁２０ｆｕｐから下側縁２０ｆｄｗまで設けられているが、高弾性部２０ＮＡは、タブ３０と左右方向に重なる領域の少なくとも一部において、上側縁２０ｆｕｐを含む上側領域、もしくは下側縁２０ｆｄｗを含む下側領域に前記高弾性部２０ＮＡが設けられている構成でもよい。前胴回り部２０ｆの上側縁２０ｆｕｐもしくは下側縁２０ｆｄｗは、図６Ｂ及び図７Ｃに示すような前胴回り部２０ｆを破る動作が行われる際に、引き裂きの開始点となる部位である。特に、図６Ｂに示すように、製品を取り出して、前胴回り部２０ｆの左右方向の一方側の端部を切り取り線２５に沿って上下方向に破るときは、使用者は、前胴回り部２０ｆの上側縁２０ｆｕｐ側から破ることが多い。そのような場合は、上側縁２０ｆｕｐを含む上側領域に高弾性部２０ＮＡが設けられていると、よりスムーズに破る動作を行いやすくなる。一方、図７Ｃに示すように、座った状態で左右方向の反対側（他方側）の端部を切り取り線２５に沿って上下方向に破るときは、使用者は、前胴回り部２０ｆの下側縁２０ｆｄｗ側から破ることが多い。そのような場合は、下側縁２０ｆｄｗを含む下側領域に高弾性部２０ＮＡが設けられていると、よりスムーズに破る動作を行いやすくなる。 Further, the high-elasticity portion 20NA of the front waist portion 20f in the present embodiment is provided from the upper edge 20fup to the lower edge 20fdw in the vertical direction, but the high-elasticity portion 20NA overlaps the tab 30 in the horizontal direction. , the high elastic portion 20NA may be provided in an upper region including the upper edge 20fup or a lower region including the lower edge 20fdw. The upper edge 20fup or the lower edge 20fdw of the front waistline portion 20f is a tear starting point when the front waistline portion 20f is broken as shown in FIGS. 6B and 7C. In particular, as shown in FIG. 6B, when taking out the product and tearing one end of the front waistline portion 20f in the left-right direction vertically along the perforation line 25, the user can cut the front waistline portion 20f. It often breaks from the upper edge 20fup side. In such a case, if the high-elasticity portion 20NA is provided in the upper region including the upper edge 20fup, the tearing action can be performed more smoothly. On the other hand, as shown in FIG. 7C, when tearing the edge on the opposite side (the other side) in the left-right direction in the sitting state in the vertical direction along the perforation line 25, the user can cut the lower side of the front waist portion 20f. It often breaks from the edge 20fdw side. In such a case, if the high-elasticity portion 20NA is provided in the lower region including the lower edge 20fdw, the tearing action can be performed more smoothly.
　ナプキン１は、成人用のパンツ型吸収性物品であるが、例えば、介護者にパンツ型吸収性物品を装着してもらう被介護者を着用対象としたパンツ型の使い捨ておむつと比較して、前胴回り部２０ｆの上下方向の長さＬ１（図８）が短い構成である。具体的には、図８に示すように、サイド接合部４０に接合されたタブ３０が左右方向の内側に閉じられた状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、前胴回り部２０ｆとタブ３０とが左右方向に重なる領域２０ｆｃにおける前胴回り部２０ｆの上下方向の長さＬ１の最小値は、８０ｍｍ以上１５０ｍｍ以下とする。 The napkin 1 is a pants-type absorbent article for adults. The vertical length L1 (FIG. 8) of the waist portion 20f is short. Specifically, as shown in FIG. 8, the tabs 30 joined to the side joints 40 are closed inward in the left-right direction and engaged with the non-skin side surfaces of the front waistline portion 20f in a natural state. In the napkin 1, the minimum value of the vertical length L1 of the front waist portion 20f in the region 20fc where the front waist portion 20f and the tab 30 overlap in the left-right direction is 80 mm or more and 150 mm or less.
　なお、ナプキン１をパッケージから取り出した初期状態が図８の状態である場合、初期状態、かつ、自然状態のナプキン１にて、測定を行う。初期状態が図８の状態でない場合（例えばタブ３０が折り畳まれている場合等）は、自然状態のナプキン１（自然状態の胴回り部材２０）に対して、サイド接合部４０から左右方向の内側に向かって広げたタブ３０を前胴回り部２０ｆに係合した状態で、測定を行う。 In addition, when the initial state of the napkin 1 taken out of the package is the state of FIG. 8, the measurement is performed with the napkin 1 in the initial state and the natural state. When the initial state is not the state shown in FIG. 8 (for example, when the tab 30 is folded), the napkin 1 in the natural state (the waist member 20 in the natural state) is positioned inside the side joint 40 in the left-right direction. The measurement is performed with the tab 30, which is spread out, engaged with the front waist portion 20f.
　タブ３０と重なる前胴回り部２０ｆの領域２０ｆｃは、図６Ｂ及び図７Ｃに示すようなタブ３０を開いて前胴回り部２０ｆを破くときに、着用者によって把持されやすい部位である。そのため、領域２０ｆｃの上下方向の長さＬ１を１５０ｍｍ以下とすることで、着用者が前胴回り部２０ｆを破り易くなる。一方、前胴回り部２０ｆの当該長さＬ１を短くし過ぎると、着用者の体を覆う面積が小さくなりすぎて着用者の不安を煽る虞があるが、領域２０ｆｃの上下方向の長さＬ１を８０ｍｍ以上とすることで、そのような不安を抑制できる。 A region 20fc of the front waist portion 20f that overlaps with the tab 30 is a portion that is likely to be gripped by the wearer when opening the tab 30 and tearing the front waist portion 20f as shown in FIGS. 6B and 7C. Therefore, by setting the vertical length L1 of the region 20fc to 150 mm or less, the wearer can easily tear the front waist portion 20f. On the other hand, if the length L1 of the front waist portion 20f is too short, the area covering the wearer's body will be too small, which may make the wearer uneasy. Such anxiety can be suppressed by making it 80 mm or more.
　また、図９に示すように、上下方・BR>・ノ長さを有する切り取り線２５は、前胴回り部２０ｆの高弾性部２０ＮＡに設けられている。切り取り線２５は、着用者が前胴回り部２０ｆを破るときの引き裂きを誘導するラインであり、そのような切り取り線２５を、伸びにくく破れ易い高弾性部２０ＮＡに設けることで、前胴回り部２０ｆをより破り易くなる。 Also, as shown in FIG. 9, a perforated line 25 having a vertical length of BR> is provided in the high-elasticity portion 20NA of the front waist portion 20f. The perforation line 25 is a line that guides tearing when the wearer breaks the front waist portion 20f. easier to break.
　また、図９に示すように、サイド接合部４０に接合されたタブ３０が左右方向の内側に閉じられた状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、上下方向におけるサイド接合部４０の長さＬ２は、切り取り線２５の長さＬ３よりも長い。切り取り線２５の長さの方が短いことにより、図６Ｂ及び図７Ｃに示すような破る動作を行うために一定の力をかけたときに、サイド接合部４０にかかる単位長さ当たりの力よりも、切り取り線２５部分にかかる単位長さ当たりの力の方が大きくなる。よって、前胴回り部２０ｆを破る際に、切り取り線２５に沿って破り易くなる。 Further, as shown in FIG. 9, the napkin 1 in its natural state is engaged with the non-skin side surface of the front waistline portion 20f in a state where the tabs 30 joined to the side joint portions 40 are closed inward in the left-right direction. , the length L2 of the side joint portion 40 in the vertical direction is longer than the length L3 of the cut line 25 . The shorter length of the tear line 25 provides less force per unit length on the side joint 40 when a constant force is applied to perform the tearing action shown in FIGS. 6B and 7C. Also, the force per unit length applied to the perforated line 25 portion is larger. Therefore, when tearing the front waist portion 20f, it becomes easy to tear along the perforation line 25. - 特許庁
　また、図９に示すような、切り取り線２５に沿って前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離される前の状態、且つ、タブ３０が前胴回り部２０ｆの非肌側面に係合している状態において、係合部３２は、左右方向において切り取り線２５よりも内側に位置している。仮に、切り取り線２５の位置が、左右方向において係合部３２よりも内側に位置する場合、例えば図７Ｃに示す破る動作を行った後で図７Ｄに示す太腿に巻き付けて位置合わせを行う際に、前胴回り部２０ｆの腹側当接部２０ｆＡの左右方向の長さが短くなり、タブ３０を取り付ける領域が減ってしまう。つまり、切り離した後で、腹側当接部２０ｆＡ側の切り取り線２５を跨ぐようにタブ３０を左右方向の内側に引っ張り寄せて固定するため、使用できる胴回りのサイズレンジが狭まってしまう。また、破かずにナプキン１を使用する場合であっても、左右方向において係合部３２よりも内側の部分においては、前胴回り部２０ｆが左右方向に伸縮する部位であり、そのような位置に切り取り線２５が設けられると、着用時に製品（ナプキン１）を引き上げた際に切り取り線２５で破け易くなってしまう。よって、本実施形態のように、係合部３２が左右方向において切り取り線２５よりも内側に位置していることで、胴回りのサイズレンジを広く取りつつ、破かずに使用する場合の引き上げ時の破断も抑制することができる。 Also, as shown in FIG. 9, the state before the ventral contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b along the cutting line 25, and the tab 30 is attached to the front waistline portion 20f. In the state of being engaged with the skin side surface, the engaging portion 32 is located inside the perforated line 25 in the left-right direction. If the cutout line 25 is located inside the engaging portion 32 in the left-right direction, for example, after performing the tearing action shown in FIG. In addition, the length in the left-right direction of the ventral contact portion 20fA of the front waist portion 20f is shortened, and the area where the tab 30 is attached is reduced. That is, after being cut off, the tab 30 is pulled inward in the left-right direction and fixed so as to straddle the perforation line 25 on the ventral contact portion 20fA side, which narrows the usable waist size range. Further, even when the napkin 1 is used without tearing, the front waist portion 20f expands and contracts in the left-right direction in the portion inside the engaging portion 32 in the left-right direction, and such a position is used. If the perforation line 25 is provided, the product (napkin 1) is easily torn at the perforation line 25 when the product (napkin 1) is pulled up during wearing. Therefore, as in the present embodiment, the engagement portion 32 is positioned inside the perforated line 25 in the left-right direction, so that the size range of the waist circumference can be widened, and when used without tearing, when pulling up Fracture can also be suppressed.
　また、同様に、切り取り線２５に沿って前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離される前の状態、且つ、タブ３０が前胴回り部２０ｆの非肌側面に係合している状態において、タブ３０は、切り取り線２５の少なくとも一部を覆うように配置されている。そして、切り取り線２５の上端２５ｕｐは、タブ３０の上端３０ｕｐよりも上側に位置する。タブ３０が前胴回り部２０ｆの切り取り線２５の全てを覆うように配置されていると、着用者は、タブ３０を左右方向の外側に開くまで切り取り線２５の位置を把握できないが、タブ３０を開く前に切り取り線２５の一部を視認できることによって、着用者はどの位置で前胴回り部２０ｆを破くべきか判断しやすくなり、装着性を向上することができる。なお、本実施形態では、切り取り線２５の下端はタブ３０によって覆われていて視認し難いが、切り取り線２５の下端がタブ３０の下端よりも下側に位置していてもよい。そうすることで、同様に、着用者は破くべき位置を判断しやすくなる。 Similarly, the state before the ventral contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b along the cut line 25, and the tab 30 is engaged with the non-skin side of the front waistline portion 20f. In the mated condition, tab 30 is positioned to cover at least a portion of tear line 25 . An upper end 25up of the perforation line 25 is located above an upper end 30up of the tab 30. As shown in FIG. If the tab 30 is arranged to cover the entire cut line 25 of the front waist portion 20f, the wearer cannot grasp the position of the cut line 25 until the tab 30 is opened laterally outward. Since a part of the perforation line 25 can be visually recognized before opening, the wearer can easily determine at which position the front waist portion 20f should be torn, and the wearability can be improved. In this embodiment, the lower end of the perforation line 25 is covered with the tab 30 and is difficult to see, but the lower end of the perforation line 25 may be positioned below the lower end of the tab 30 . By doing so, it is likewise easier for the wearer to determine where to tear.
　また、高弾性部２０ＮＡは、前胴回り部２０ｆの側縁２０ｆｅから切り取り線２５よりも左右方向の内側に延在しているが、自然状態において、高弾性部２０ＮＡは、切り取り線２５から左右方向の内側に向かって１０ｍｍ以上の長さ（図９の長さＷ２０）を有していることが好ましい。前胴回り部２０ｆを切り取り線２５に沿って破った後、切り取り線２５よりも内側に配置されている高弾性部２０ＮＡの部分は、着用者がタブ３０を前胴回り部２０ｆ（腹側当接部２０ｆＡ）の非肌面側に係合するときのつまみとなる部位である。高弾性部２０ＮＡは変形しにくいため、当該つまみとなる部分が高弾性部２０ＮＡであることで丸まりにくく、着用者はつまみ易くなる。また、長さＷ２０が１０ｍｍ以上あることで、着用者の親指の幅に近いか、或いは親指の幅以上となり、よりつまみ易くなる。 In addition, the high-elasticity portion 20NA extends from the side edge 20fe of the front waist portion 20f to the inner side of the cutoff line 25 in the left-right direction. It preferably has a length of 10 mm or more (length W20 in FIG. 9) toward the inner side of the . After tearing the front waist portion 20f along the cut line 25, the portion of the high elastic portion 20NA that is arranged inside the cut line 25 is used by the wearer when the tab 30 is pulled from the front waist portion 20f (abdominal contact portion). 20fA) is a part that becomes a knob when engaging with the non-skin surface side. Since the high-elasticity portion 20NA is difficult to deform, the high-elasticity portion 20NA that serves as the knob is less likely to curl up, making it easier for the wearer to pick it up. In addition, when the length W20 is 10 mm or more, it is close to the width of the thumb of the wearer or equal to or greater than the width of the thumb of the wearer, making it easier to pick up.
　着用者が前胴回り部２０ｆからタブ３０を剥離させる（係合を解く）ときには、着用者は、タブ３０の先端側を持って剥離させることが想定される。図９に示すように、左右方向において、係合部３２の内側端３２ｅからタブ３０の内側端３０ｅまでの長さＷ３０は、５ｍｍ以上５０ｍｍ以下であることが好ましい。係合部３２の内側端３２ｅからタブ３０の内側端３０ｅまでの長さＷ３０を５ｍｍ以上とすることで、指先で係合部３２の内側端３２ｅよりも内側をつまんで、前胴回り部２０ｆからタブ３０を剥離しやすくなる。一方、長さＷ３０を５０ｍｍ以下とすることで、タブ３０をつまんだ位置から切り取り線２５までの距離が長くなり過ぎず、切り取り線２５に沿って前胴回り部２０ｆを破るときの操作性の低下を防ぐことができる。 When the wearer peels off (disengages) the tab 30 from the front waist portion 20f, it is assumed that the wearer holds the tip side of the tab 30 and peels it off. As shown in FIG. 9, the length W30 from the inner end 32e of the engaging portion 32 to the inner end 30e of the tab 30 in the left-right direction is preferably 5 mm or more and 50 mm or less. By setting the length W30 from the inner end 32e of the engaging portion 32 to the inner end 30e of the tab 30 to be 5 mm or more, the inner side of the inner end 32e of the engaging portion 32 can be pinched with the fingertips, and the front waist portion 20f can be pulled out. The tab 30 can be easily peeled off. On the other hand, by setting the length W30 to 50 mm or less, the distance from the position where the tab 30 is pinched to the perforation line 25 does not become too long, and the operability when tearing the front waist portion 20f along the perforation line 25 is lowered. can be prevented.
　また、図２に示すように、展開かつ伸張状態であるパンツ型吸収性物品１において、左右方向におけるタブ３０の最大長さＷ５は、２０ｍｍ以上１２０ｍｍ以下であることが好ましい。タブ３０の左右方向の長さＷ５を２０ｍｍ以上とすることで、着用者がタブ３０を前胴回り部２０ｆに係合する際に、タブ３０を持ち易くなる。一方、タブ３０の左右方向の長さＷ６を１２０ｍｍ以下とすることで、太腿にナプキン１を巻き付けた際に、外側に開いたタブ３０の便器への接触を抑制できる。また、タブ３０の左右方向の長さＷ５を長くし過ぎないことで、着用者は、タブ３０を開いて前胴回り部２０ｆを破いた後に、前胴回り部２０ｆに係合部３２を係合しやすくなるように係合部３２に近い位置にタブ３０を持ち替える必要がなくなる。 Further, as shown in FIG. 2, in the pants-type absorbent article 1 in the unfolded and stretched state, the maximum length W5 of the tabs 30 in the left-right direction is preferably 20 mm or more and 120 mm or less. By setting the length W5 of the tab 30 in the left-right direction to 20 mm or more, the wearer can easily hold the tab 30 when engaging the tab 30 with the front waist portion 20f. On the other hand, by setting the length W6 of the tab 30 in the lateral direction to 120 mm or less, it is possible to suppress the contact of the tab 30 opened to the outside with the toilet bowl when the napkin 1 is wrapped around the thigh. Also, by not making the length W5 of the tab 30 in the horizontal direction too long, the wearer can engage the engaging portion 32 with the front waist portion 20f after opening the tab 30 and tearing the front waist portion 20f. There is no need to switch the tab 30 to a position closer to the engaging portion 32 to make it easier.
　また、本実施形態のタブ３０を構成する基材シート３１は、不織布等であり、実質的にはタブ３０自体が伸縮する要素を備えていない。タブ３０を前胴回り部２０ｆと比較すると、タブ３０は、前胴回り部２０ｆの高弾性部２０ＮＡよりもさらに弾性係数が大きい。
つまり、タブ３０は、高弾性部２０ＮＡよりもより変形しにくい（伸びにくい）。よって、図６Ｂ及び図７Ｃのようにタブ３０と前胴回り部２０ｆとを持って、切り取り線２５に沿って破るときに、タブ３０を引っ張る力が前胴回り部２０ｆの高弾性部２０ＮＡに伝わり易い。 Further, the base sheet 31 constituting the tab 30 of the present embodiment is made of nonwoven fabric or the like, and substantially does not include elements that allow the tab 30 itself to expand and contract. Comparing the tab 30 with the front waistline portion 20f, the tab 30 has a larger modulus of elasticity than the high-elasticity portion 20NA of the front waistline portion 20f.
That is, the tab 30 is more difficult to deform (stretch) than the highly elastic portion 20NA. Therefore, when the tab 30 and the front waistline portion 20f are held and broken along the perforation line 25 as shown in FIGS. 6B and 7C, the force of pulling the tab 30 is easily transmitted to the high elastic portion 20NA of the front waistline portion 20f. .
　また、図２に戻り、展開かつ伸張状態であるナプキン１において、上下方向（左右方向に直交する方向であり、吸収性本体１０の長手方向に沿う方向）におけるナプキン１の一方側の端から中心ＣＬまでの長さＬ６が、２００ｍｍ以上３５０ｍｍ以下であることが好ましい。長さＬ６を２００ｍｍ以上とすることで、成人であるナプキン１の着用者のサイズに合わせることができる。一方、長さＬ６を３５０ｍｍ以下とすることで、太腿にナプキン１を巻き付けた際に、ナプキン１が垂れ下がり難く、ナプキン１の便器への接触を抑制できる。 2, in the napkin 1 in the unfolded and stretched state, from one end of the napkin 1 to the center in the vertical direction (the direction orthogonal to the left-right direction and along the longitudinal direction of the absorbent body 10) The length L6 to CL is preferably 200 mm or more and 350 mm or less. By setting the length L6 to 200 mm or more, it is possible to match the size of the napkin 1 to an adult wearer. On the other hand, by setting the length L6 to 350 mm or less, when the napkin 1 is wrapped around the thigh, it is difficult for the napkin 1 to hang down, and the contact of the napkin 1 to the toilet bowl can be suppressed.
　本実施形態のナプキン１では、図８に示すように、前胴回り部２０ｆは平面視において、一対のタブ３０と重なる左右方向の両側の重なり領域２０ｆｃのそれぞれの少なくとも一部に高弾性部２０ＮＡ、２０ＮＡを有している。そして、前胴回り部２０ｆの左右方向の両側にある高弾性部２０ＮＡ、２０ＮＡの間には、高弾性部２０ＮＡよりも弾性係数が小さい低弾性部２０ＥＡが連続して設けられている。低弾性部２０ＥＡは、図５に示すように、肌側シート２２及び胴回り弾性部材２４によって左右方向に伸縮する部位である。
低弾性部２０ＥＡを有することで、ナプキン１が着用者の胴回りにフィットする。特に、ナプキン１がテープ型として使用される場合（図４Ｂ）、前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離されるが、一対のタブ３０の間で腹側当接部２０ｆＡが左右方向の両外側に引っ張られ、着用者の胴回りにフィットしやすくなる。また、タブ３０を装着した後に、係合部３２よりも左右方向外側に高弾性部２０ＮＡ、２０ＮＡがそれぞれ設けられている。さらに、該高弾性部２０ＮＡ、２０ＮＡは、タブ３０よりも肌側に存在することとなる。高弾性部２０ＮＡは変形しにくいため、前胴回り部２０ｆの左右方向端部が丸まりにくくなり、そのような高弾性部２０ＮＡが装着時に肌と接する部分であることから、着用者の違和感を低減させることもできる。 In the napkin 1 of the present embodiment, as shown in FIG. 8, the front waist portion 20f includes, in a plan view, a high elastic portion 20NA, a high elastic portion 20NA, and a high elastic portion 20NA in at least a portion of each of the overlapping regions 20fc on both sides in the left and right direction overlapping the pair of tabs 30 in plan view. It has 20 NA. A low-elasticity portion 20EA having a smaller elastic modulus than the high-elasticity portion 20NA is continuously provided between the high-elasticity portions 20NA, 20NA on both sides in the left-right direction of the front waist portion 20f. The low-elasticity portion 20EA is a portion that expands and contracts in the left-right direction by the skin-side sheet 22 and the waist elastic member 24, as shown in FIG.
By having the low-elasticity portion 20EA, the napkin 1 fits the waist of the wearer. In particular, when the napkin 1 is used as a tape type (FIG. 4B), the ventral contact portion 20fA of the front waistline portion 20f is separated from the back waistline portion 20b, but the ventral contact portion 20fA of the front waistline portion 20f is separated from the back waistline portion 20b. The portion 20fA is pulled outward on both sides in the left-right direction, making it easier to fit around the waist of the wearer. Further, after the tab 30 is attached, the high-elasticity portions 20NA, 20NA are provided outside the engaging portion 32 in the left-right direction. Furthermore, the highly elastic portions 20NA, 20NA are present closer to the skin than the tab 30 is. Since the high-elasticity portion 20NA is hard to deform, the left-right direction end portions of the front waist portion 20f are less likely to curl up, and since such a high-elasticity portion 20NA is a portion that comes into contact with the skin when worn, it reduces discomfort of the wearer. can also
　また、タブ３０の係合部３２が前胴回り部２０ｆに係合した状態、且つ、平面視において、低弾性部２０ＥＡは、係合部３２の少なくとも一部と重なる部分を有することが好ましい。係合部３２は、変形しにくい高弾性部２０ＮＡよりも、変形しやすい（伸縮しやすい）低弾性部２０ＥＡの部分に係合しやすい。すなわち、係合部３２が備える繊維に引っ掛かるための突起は、ピンと張った状態に近い部分に引っ掛けるよりも、収縮によって皺が寄っている部分に引っ掛ける方が、引っ掛かりやすい。よって、係合部３２を係合させるときに、低弾性部ＥＡと重なる部分を有することで、着用者は、係合部３２をより係合させやすくなる。 Also, in a state where the engaging portion 32 of the tab 30 is engaged with the front waist portion 20f and in a plan view, the low elastic portion 20EA preferably has a portion that overlaps at least a portion of the engaging portion 32. The engaging portion 32 is more likely to engage with the easily deformable (easily stretchable) low-elasticity portion 20EA than with the hard-to-deform high-elasticity portion 20NA. In other words, the projections of the engaging portion 32 for catching on the fibers are more likely to catch on the wrinkled part due to contraction than on the part that is nearly taut. Therefore, when engaging the engaging portion 32 , having a portion that overlaps with the low elastic portion EA makes it easier for the wearer to engage the engaging portion 32 .
　図１０は、切り取り線２５に沿って分離させた後、タブ３０を係合させた状態のナプキン１を前側から見た正面図である。図１０に示すナプキン１は、切り取り線２５に沿って前胴回り部２０ｆの腹側当接部２０ｆＡを後胴回り部２０ｂから分離した後、分離後の腹側当接部２０ｆＡを自然状態で広げてタブ３０を前胴回り部２０ｆの非肌側面に係合させた状態である。同図に示すように、タブ３０を係合させた状態において、タブ３０は、前胴回り部２０ｆの下側縁２０ｆｄｗよりも上下方向の下側に突出する突出部３０Ｔを有する。テープ型として使用するために、切り取り線２５に沿って前胴回り部２０ｆを破いて、再度タブ３０を係合させた状態においても、タブ３０の突出部３０Ｔによって、前胴回り部２０ｆの下側縁２０ｆｄｗの左右方向の両端が隠れることにより、破った後の前胴回り部２０ｆの端（下側縁２０ｆｄｗ）が見えにくくなる。そうすることで、ナプキン１をより下着らしい外観に近づけることができる。 FIG. 10 is a front view of the napkin 1 with the tab 30 engaged after being separated along the tear line 25, viewed from the front side. In the napkin 1 shown in FIG. 10, after separating the ventral contact portion 20fA of the front waistline portion 20f from the back waistline portion 20b along the cutting line 25, the separated ventral contact portion 20fA is spread in a natural state. The tab 30 is engaged with the non-skin side of the front waist portion 20f. As shown in the figure, when the tab 30 is engaged, the tab 30 has a projecting portion 30T projecting downward in the vertical direction from the lower edge 20fdw of the front waistline portion 20f. In order to use it as a tape type, even when the front waistline portion 20f is torn along the perforation line 25 and the tab 30 is engaged again, the lower edge of the front waistline portion 20f can be pulled by the projecting portion 30T of the tab 30. By hiding the left and right ends of 20fdw, it becomes difficult to see the end (lower side edge 20fdw) of the front waistline portion 20f after being torn. By doing so, it is possible to make the napkin 1 look more like underwear.
＝＝＝その他＝＝＝
　上述の実施形態では、胴回り部材２０を構成する肌側シート２２，２３として、伸縮不織布等の伸縮性シートを用いることによって、胴回り部材２０に左右方向の伸縮性を付与していたが、胴回り部材２０に他の伸縮部材が設けられていても良い。例えば、図２のように、前胴回り部２０ｆ及び後胴回り部２０ｂの上端部に、それぞれ糸ゴム等の胴回り弾性部材２４が左右方向に沿って伸縮可能に設けられていても良い。このような胴回り弾性部材２４が設けられることにより、胴回り開口１ａにおけるフィット性がより高まり、ナプキン１の着用時に、胴回り部材２０の位置ずれを抑制することができる。 ===Others===
In the above-described embodiment, stretchable sheets such as stretchable nonwoven fabric are used as the skin- side sheets 22 and 23 constituting the waist member 20, thereby imparting stretchability to the waist member 20 in the left-right direction. 20 may be provided with other elastic members. For example, as shown in FIG. 2, waist elastic members 24 such as rubber threads may be provided at the upper ends of the front waist portion 20f and the rear waist portion 20b so as to be able to expand and contract along the left-right direction. By providing such a waist elastic member 24, the fit to the waist opening 1a is further improved, and displacement of the waist member 20 when the napkin 1 is worn can be suppressed.
　上述の実施形態では、タブ３０が胴回り部材２０の左右方向両側に設けられていたが、片側のみに設けられていても良い。そして、例えば使用時に、そのような片側のみに設けられているタブ３０を引っ張ることで、前胴回り部２０ｆにおいて剛性差が大きいサイド接合部４０の左右方向内側端に沿って容易に引き裂くことができる構成であっても良い。それにより、使用する際に、片側のみ展開可能なパンツ型ナプキンとなる。この場合、サイド接合部４０の左右方向内側端が本実施形態の切り取り線２５として機能するため、ミシン目等は必ずしも設けられなくてもよい。 In the above-described embodiment, the tabs 30 are provided on both sides in the left-right direction of the waist member 20, but may be provided on only one side. For example, by pulling the tab 30 provided only on one side during use, the front waist portion 20f can be easily torn along the left-right direction inner end of the side joint portion 40 having a large difference in rigidity. It may be a configuration. As a result, the underpants-type napkin can be unfolded only on one side when used. In this case, since the left-right direction inner end of the side joint portion 40 functions as the perforation line 25 of the present embodiment, the perforation or the like does not necessarily have to be provided.

　本実施形態に係るパンツ型吸収性物品の一例として、パンツ型（ショーツ型）ナプキン１（以下、ナプキン１とも呼ぶ）について説明する。なお、パンツ型吸収性物品には、パンツ型おむつやパンツ型吸収パッド等も含まれる。 === Second Embodiment and Third Embodiment ===
As an example of the pants-type absorbent article according to the present embodiment, a pants-type (shorts-type) napkin 1 (hereinafter also referred to as a napkin 1) will be described. The pants-type absorbent article also includes pants-type diapers, pants-type absorbent pads, and the like.
＜＜＜第２実施形態及び第３実施形態のナプキン１の基本的構造＞＞＞
　図１は、ナプキン１の概略斜視図である。図１１は、展開かつ伸長状態のナプキン１を厚さ方向の肌側から見た概略平面図である。図１２は、図１１のＡ－Ａ断面模式図である。 <<<basic structure of the napkin 1 of the second and third embodiments>>>
FIG. 1 is a schematic perspective view of the napkin 1. FIG. FIG. 11 is a schematic plan view of the napkin 1 in an unfolded and stretched state, viewed from the skin side in the thickness direction. FIG. 12 is a schematic cross-sectional view taken along the line AA of FIG. 11. FIG.
　ナプキン１は、図１に示すように、互いに交差（直交）する「上下方向（又は縦方向）」と「左右方向（又は幅方向）」と「前後方向」とを有している。また、図１２に示すように、各部材が積層された方向である「厚さ方向」を有している。上下方向（縦方向）のうち、着用者がナプキン１を着用した状態において着用者の胴回り側となる方を「上側」とし、着用者の股下側となる方を「下側」とする。また、前後方向のうち、着用時に着用者の腹側となる方を「前側」とし、着用者の背側となる方を「後側」とする。また、厚さ方向のうち、着用者がナプキン１を着用した状態において着用者の肌と接触する側を「肌側」とし、その反対側を「非肌側」とする。 As shown in FIG. 1, the napkin 1 has "vertical direction (or vertical direction)", "horizontal direction (or width direction)" and "front-back direction" that intersect (perpendicularly) each other. Moreover, as shown in FIG. 12, it has a "thickness direction" which is the direction in which each member is laminated. In the vertical direction (longitudinal direction), when the wearer wears the napkin 1, the waist side of the wearer is defined as the "upper side", and the crotch side of the wearer is defined as the "lower side". Further, of the front-to-rear directions, the side facing the wearer's abdomen when worn is defined as the "front side", and the side facing the wearer's back is defined as the "rear side". In addition, in the thickness direction, the side that comes into contact with the wearer's skin when the napkin 1 is worn by the wearer is defined as the "skin side", and the opposite side is defined as the "non-skin side".
　本実施形態のナプキン１は、経血等の排泄液を吸収する吸収性本体１０と、前後方向に吸収性本体１０と重ねて配置され（本実施形態では吸収性本体１０の非肌側に配置された）、前胴回り部２０ｆ及び後胴回り部２０ｂを備える胴回り部材２０と、胴回り部材２０の左右方向（幅方向）の両側に設けられた一対のタブ３０と、を備えている。 The napkin 1 of this embodiment includes an absorbent body 10 that absorbs excretory fluid such as menstrual blood, and an absorbent body 10 that overlaps the absorbent body 10 in the front-rear direction (in this embodiment, it is placed on the non-skin side of the absorbent body 10). ), a waist member 20 including a front waist portion 20f and a rear waist portion 20b, and a pair of tabs 30 provided on both sides of the waist member 20 in the left-right direction (width direction).
　図１１に示されるナプキン１の展開状態とは、ナプキン１の左右方向（幅方向）の両側部に設けられている一対のサイド接合部４０を分離し、ナプキン１を開いて平面的に展開した状態である。換言すると、ナプキン１は、図１１に示す展開状態から、上下方向（縦方向）における中央位置ＣＬ（二つ折り部Ｆ）で前後方向に二つ折りされ、前胴回り部２０ｆ及び後胴回り部２０ｂそれぞれの左右方向（幅方向）の両側部が一対のサイド接合部４０（接合部）にて接合されてパンツ型となる。サイト接合部４０における接合方法としては熱溶着や超音波溶着等の周知の接合方法が挙げられる。パンツ型のナプキン１（図１）では、前胴回り部２０ｆ及び後胴回り部２０ｂが環状につながっており、１つの胴回り開口１ａ及び一対の脚回り開口１ｂが形成されている。 The unfolded state of the napkin 1 shown in FIG. 11 means that the pair of side joints 40 provided on both sides of the napkin 1 in the left-right direction (width direction) are separated, and the napkin 1 is opened and unfolded in a plane. state. In other words, the napkin 1 is folded in half in the longitudinal direction at the central position CL (half-folded portion F) in the vertical direction (longitudinal direction) from the unfolded state shown in FIG. Both sides in the left-right direction (width direction) are joined at a pair of side joints 40 (joints) to form a pants type. As a bonding method for the site bonding portion 40, a well-known bonding method such as heat welding or ultrasonic welding can be used. In the underpants-type napkin 1 (FIG. 1), a front waist portion 20f and a rear waist portion 20b are connected in an annular fashion to form one waist opening 1a and a pair of leg openings 1b.
　ナプキン１の伸張状態とは、ナプキン１の皺が視認できなくなる程まで、ナプキン１が備える弾性部材を伸張させた状態である。具体的には、ナプキン１を構成する各部材の寸法が、その部材単体の寸法（すなわち弾性部材の弾性特性が発現しない状態での寸法）と一致又はそれに近い寸法になるまで伸張させた状態である。なお、本実施形態において、ナプキン１の本体部の長さ等を測定、比較する場合、タブ３０の係合を解いた状態（又はタブ３０を分離（剥離）した状態）で、かつ、切り取り線２６で胴回り部材２０を破る前の状態で測定、比較することが好ましい。一方、タブ３０（係合部材）の長さ等の測定は、タブ３０が胴回り部材２０に係合している状態であっても、係合を解いた状態であってもよいし、タブ３０を胴回り部材２０から分離した状態でもよい。ただし、この測定、比較の方法は一例であって、他の方法であってもよい。 The stretched state of the napkin 1 is a state in which the elastic members of the napkin 1 are stretched to such an extent that the wrinkles of the napkin 1 are no longer visible. Specifically, the dimensions of each member constituting the napkin 1 are the dimensions of the member itself (that is, the dimension of the elastic member in a state in which the elastic characteristics are not expressed), and are stretched until they are the same or close to the dimensions. be. In this embodiment, when measuring and comparing the length of the main body of the napkin 1, the tab 30 is disengaged (or the tab 30 is separated (peeled off)) and the cut line It is preferable to measure and compare in a state before the girth member 20 is broken at 26 . On the other hand, the length of the tab 30 (engagement member) may be measured with the tab 30 engaged with the waist member 20 or with the engagement released. may be separated from the waist member 20. However, this measurement and comparison method is just an example, and other methods may be used.
　（吸収性本体１０）
　吸収性本体１０は、図１１に示すように、その長手方向がナプキン１の上下方向（縦方向）に沿った平面視長方形状の部材である。そして、図１２に示すように、吸収性本体１０は、吸収性コア１１と、吸収性コア１１よりも肌側に配置されたトップシート１２と、吸収性コア１１よりも非肌側に配置されたバックシート１３と、を有している。但し、吸収性本体１０が、これ以外のシート部材を備えていてもよい。例えば、トップシート１２と吸収性コア１１との厚さ方向の間に、セカンドシート（不図示）を備えていてもよい。 (Absorptive main body 10)
As shown in FIG. 11, the absorbent main body 10 is a member having a rectangular shape in plan view, the longitudinal direction of which extends along the vertical direction (longitudinal direction) of the napkin 1 . As shown in FIG. 12, the absorbent main body 10 includes an absorbent core 11, a top sheet 12 arranged on the skin side of the absorbent core 11, and a non-skin side of the absorbent core 11. and a back sheet 13 . However, the absorbent main body 10 may be provided with sheet members other than this. For example, a second sheet (not shown) may be provided between the top sheet 12 and the absorbent core 11 in the thickness direction.
　吸収性コア１１は、経血等の液体を吸収して保持する部材であり、例えば高吸収性ポリマー（ＳＡＰ）が混入したパルプ繊維等の液体吸収性繊維により形成される。なお、吸収性コア１１は、ティッシュペーパーや不織布等の液透過性のシート部材（コアラップシート）によって、外周面が覆われていてもよい。 The absorbent core 11 is a member that absorbs and retains liquid such as menstrual blood, and is formed of, for example, liquid-absorbent fibers such as pulp fibers mixed with superabsorbent polymer (SAP). The outer peripheral surface of the absorbent core 11 may be covered with a liquid-permeable sheet member (core wrap sheet) such as tissue paper or nonwoven fabric.
　トップシート１２は、着用時において着用者の肌に接触し得る液透過性のシート部材であり、例えば親水性のエアスルー不織布やスパンボンド不織布等により形成される。 The top sheet 12 is a liquid-permeable sheet member that can come into contact with the wearer's skin when worn, and is made of, for example, a hydrophilic air-through nonwoven fabric or spunbond nonwoven fabric.
　バックシート１３は、吸収性コア１１に吸収された経血等の液体が外部に漏れ出すことを抑制するための液不透過性シート１３ａと、液不透過性シート１３ａの非肌側に配置された疎水性シート１３ｂと、を備えた二層構造で形成されている。液不透過性シート１３ａとしては、例えば樹脂フィルム等が用いられ、疎水性シート１３ｂとしては、例えば柔軟性を有する不織布等が用いられる。但し、疎水性シート１３ｂは必ずしも設けられていなくても良く、液不透過性シート１３ａのみによってバックシート１３が構成されていてもよい。 The back sheet 13 is arranged on the non-skin side of the liquid-impermeable sheet 13a for suppressing leakage of liquid such as menstrual blood absorbed by the absorbent core 11 to the outside, and the liquid-impermeable sheet 13a. and a hydrophobic sheet 13b. For example, a resin film or the like is used as the liquid-impermeable sheet 13a, and a flexible non-woven fabric or the like is used as the hydrophobic sheet 13b. However, the hydrophobic sheet 13b may not necessarily be provided, and the back sheet 13 may be composed only of the liquid-impermeable sheet 13a.
　また、吸収性本体１０は、左右方向（幅方向）の両側部において、肌側に起立可能な防漏壁部１４を有する。例えば、疎水性シート１３ｂの左右方向（幅方向）の両側部が、トップシート１２の肌側面上に位置するように左右方向（幅方向）の内側に折り返されて、その折り返された部位に長手方向に伸縮する防漏壁弾性部材１４１（例えば糸ゴム）が設けられることにより、防漏壁部１４が形成される。防漏壁部１４によって排泄液の横漏れを抑制できる。但し、吸収性本体１０に防漏壁部１４が設けられていなくてもよい。 In addition, the absorbent main body 10 has leak-proof walls 14 that can stand up on the skin side on both sides in the left-right direction (width direction). For example, both sides of the hydrophobic sheet 13b in the left-right direction (width direction) are folded inward in the left-right direction (width direction) so as to be positioned on the skin side surface of the top sheet 12, and the folded portions are longitudinally folded. The leak-proof wall portion 14 is formed by providing the leak-proof wall elastic member 141 (for example, rubber thread) that expands and contracts in the direction. The leak-proof wall portion 14 can suppress lateral leakage of the excreted liquid. However, the absorbent main body 10 may not be provided with the leak-proof wall portion 14 .
　また、吸収性本体１０には、その長手方向に沿って伸縮する吸収体弾性部材１５が複数設けられている。吸収体弾性部材１５は、例えば糸ゴムによって構成され、吸収性コア１１の非肌側に位置する液不透過性シート１３ａよりも非肌側（図１２では、液不透過性シート１３ａと疎水性シート１３ｂとの間）に、長手方向に伸長した状態で配置されている。本実施形態のナプキン１では、左右方向に所定の間隔を空けて５本の吸収体弾性部材１５が設けられている（図１１参照）。吸収体弾性部材１５の伸長倍率は１．４～３．３倍程度とすることが好ましい。なお、伸長倍率は、伸長状態の弾性部材の長さを自然状態の弾性部材の長さで除した値で表される。吸収体弾性部材１５の伸長倍率をある程度強い倍率に設定しておくとよい。そうすることで、後述の図１７に示すように、吸収性本体１０が着用者の肌側に持ち上げられ、吸収性本体１０が着用者の股下部（膣口）に密着しやすくなり、排泄液の漏れを抑制できる。 In addition, the absorbent main body 10 is provided with a plurality of absorbent elastic members 15 that expand and contract along its longitudinal direction. The absorbent elastic member 15 is made of thread rubber, for example, and is positioned closer to the non-skin side than the liquid-impermeable sheet 13a located on the non-skin side of the absorbent core 11 (in FIG. 12, the liquid-impermeable sheet 13a and the hydrophobic and the sheet 13b) in a state of being stretched in the longitudinal direction. In the napkin 1 of this embodiment, five absorbent body elastic members 15 are provided at predetermined intervals in the horizontal direction (see FIG. 11). The expansion ratio of the absorbent elastic member 15 is preferably about 1.4 to 3.3 times. The extension ratio is expressed by a value obtained by dividing the length of the elastic member in the stretched state by the length of the elastic member in the natural state. It is preferable to set the extension ratio of the absorbent body elastic member 15 to a relatively large ratio. By doing so, as shown in FIG. 17 to be described later, the absorbent main body 10 is lifted toward the wearer's skin side, and the absorbent main body 10 is easily brought into close contact with the wearer's crotch (vaginal opening), and excretions are removed. leakage can be suppressed.
　（胴回り部材２０）
　胴回り部材２０は、複数のシート部材によって構成された外装体であり、少なくとも非肌側シート２１と、肌側シート２２，２３とを備えている（図１２参照）。以下の説明では、展開状態のナプキン１（図１１）を上下方向（縦方向）の中央位置ＣＬで２分割したときに、前側の胴回り部材２０のうち、上下方向（縦方向）の位置がサイド接合部４０と重複する部位を「前胴回り部２０ｆ」と呼び、それよりも下側（股下側）の部位を「前側延出部２０ｆe」と呼ぶ。同様に、中央位置ＣＬよりも後側の胴回り部材２０のうち、上下方向（縦方向）の位置がサイド接合部４０と重複する部位を「後胴回り部２０ｂ」と呼び、それよりも下側の部位を「後側延出部２０ｂe」と呼ぶ。 (Waist circumference member 20)
The waist member 20 is an outer body composed of a plurality of sheet members, and includes at least a non-skin-side sheet 21 and skin-side sheets 22 and 23 (see FIG. 12). In the following description, when the napkin 1 ( FIG. 11 ) in the unfolded state is divided into two at the center position CL in the vertical direction (vertical direction), the vertical direction (vertical direction) position of the front waist member 20 is the side A portion that overlaps with the joint portion 40 is called a "front waist portion 20f", and a portion below it (on the crotch side) is called a "front side extending portion 20fe". Similarly, of the waist member 20 on the rear side of the central position CL, a portion that overlaps the side joint portion 40 in the vertical direction (longitudinal direction) is called a “rear waist portion 20b”. The part is called "rear side extension part 20be".
　非肌側シート２１は、ナプキン１の最も非肌側に配置される非伸縮性のシート部材であり、例えばスパンボンド不織布やＳＭＳ不織布等により形成される。本実施形態の非肌側シート２１は、図１１で示されるように、縦方向の中央部において左右方向（幅方向）内側に向かって括れた形状を有している。 The non-skin-side sheet 21 is a non-stretchable sheet member arranged on the most non-skin side of the napkin 1, and is formed of, for example, spunbond nonwoven fabric or SMS nonwoven fabric. As shown in FIG. 11, the non-skin-side sheet 21 of the present embodiment has a shape constricted inward in the left-right direction (width direction) at the central portion in the longitudinal direction.
　肌側シート２２，２３は、胴回り部材２０の前側と後側において、非肌側シート２１の肌側に積層された伸縮性のシート部材である。肌側シート２２，２３は、少なくともナプキン１の左右方向（幅方向）に伸縮性を有する。伸縮性のシート部材としては、伸縮性不織布や伸縮性フィルムが挙げられ、本実施形態の肌側シート２２，２３は伸縮性不織布とする。 The skin- side sheets 22 and 23 are stretchable sheet members laminated on the skin side of the non-skin-side sheet 21 on the front and rear sides of the waist member 20 . The skin- side sheets 22 and 23 have elasticity at least in the lateral direction (width direction) of the napkin 1 . Stretchable sheet members include stretchable nonwoven fabrics and stretchable films, and the skin- side sheets 22 and 23 of this embodiment are made of stretchable nonwoven fabrics.
　伸縮性不織布とは、伸縮性を有する伸縮性繊維、及び伸縮性繊維よりも収縮性の低い伸長性繊維を含み、ギア延伸等の適宜な延伸処理が施された伸縮性不織布とする。伸縮性繊維としては、弾性を有する熱可塑性エラストマーの一種であるポリウレタン系エラストマーの繊維を用いることが可能であり、伸長性繊維としては、非弾性を有する熱可塑性樹脂の一種であるポリオレフィン系樹脂のポリプロピレン（ＰＰ）の繊維を用いることが可能である。 A stretchable nonwoven fabric is a stretchable nonwoven fabric that contains stretchable fibers and stretchable fibers that are less shrinkable than stretchable fibers, and that has undergone appropriate stretching such as gear stretching. As the stretchable fiber, it is possible to use a polyurethane elastomer fiber, which is a type of thermoplastic elastomer having elasticity. It is possible to use fibers of polypropylene (PP).
　非肌側シート２１と肌側シート２２，２３は、点在する不図示の接合部（熱溶着や超音波溶着等による接合部）によって間欠に接合されている。よって、肌側シート２２，２３が配された胴回り部材２０の部位には、左右方向（幅方向）に沿った伸縮性が付与される。また、胴回り部材２０が収縮すると、接合部間において非肌側シート２１が撓み（凸形状となり）、胴回り部材２０の肌触りが向上し、視覚的にも柔らかい印象となる。 The non-skin-side sheet 21 and the skin- side sheets 22 and 23 are intermittently joined by scattered joints (joints by thermal welding, ultrasonic welding, or the like), not shown. Therefore, the parts of the waist member 20 on which the skin- side sheets 22 and 23 are arranged are imparted with stretchability along the left-right direction (width direction). Further, when the waist member 20 contracts, the non-skin side sheet 21 bends (has a convex shape) between the joints, and the feel of the waist member 20 is improved, giving a visually soft impression.
　なお、胴回り部材２０を構成するシート部材として、非肌側シート２１及び肌側シート２２，２３以外の他のシート部材が設けられていても良い。例えば、胴回り部材２０は、伸縮性の肌側シート２２，２３のさらに肌側に、非伸縮性不織布が配置され、伸縮性不織布が非伸縮性の不織布によって挟まれた３層構造であっても良い。また、非肌側シート２１が前側と後側とで分離されていてもよい。その場合、前側の非肌側シート２１と後側の非肌側シート２１の間で、バックシート１３の非肌側面が露出していてもよいし、前側の非肌側シート２１と後側の非肌側シート２１を繋ぐ別体の非肌側シートが股下部に設けられていてもよい。 Note that sheet members other than the non-skin-side sheet 21 and the skin- side sheets 22 and 23 may be provided as sheet members constituting the waist member 20 . For example, the waist member 20 may have a three-layer structure in which a non-stretchable non-woven fabric is arranged on the skin side of the stretchable skin- side sheets 22 and 23, and the stretchable non-woven fabric is sandwiched between the non-stretchable non-stretchable non-woven fabrics. good. Moreover, the non-skin side sheet 21 may be separated into the front side and the back side. In that case, the non-skin side of the back sheet 13 may be exposed between the front non-skin side sheet 21 and the rear non-skin side sheet 21, or the front non-skin side sheet 21 and the rear non-skin side sheet 21 may be exposed. A separate non-skin-side sheet connecting the non-skin-side sheet 21 may be provided at the crotch portion.
　（タブ３０）
　ナプキン１は、胴回り部材２０の左右方向（幅方向）の両側部において、前胴回り部２０ｆの非肌側面に取り外し可能に係合する一対のタブ３０（係合部材）を有する。なお、図１１では、肌側から見たナプキン１において、前胴回り部２０ｆの非肌側面に係合されているタブ３０を仮想的に示している。タブ３０は、基材シート３１と、係合部３２と、を有している。基材シート３１は、不織布等からなるシート部材である。基材シート３１の左右方向（幅方向）の外側端部が、サイド接合部４０によって胴回り部材２０に接合されている。つまり、サイド接合部４０によって、前胴回り部２０ｆと、後胴回り部２０ｂと、タブ３０とが一体的に接合されている。但し、サイド接合部４０とは異なる部位にてタブ３０が胴回り部材２０に接合されていてもよい。 (Tab 30)
The napkin 1 has a pair of tabs 30 (engagement members) detachably engaged with the non-skin side surfaces of the front waist portion 20f on both sides of the waist member 20 in the left-right direction (width direction). In addition, FIG. 11 virtually shows the tab 30 engaged with the non-skin side surface of the front waist portion 20f in the napkin 1 viewed from the skin side. The tab 30 has a base sheet 31 and an engaging portion 32 . The base sheet 31 is a sheet member made of nonwoven fabric or the like. Outer ends of the base sheet 31 in the left-right direction (width direction) are joined to the waist member 20 by side joints 40 . That is, the front waistline portion 20f, the rear waistline portion 20b, and the tab 30 are integrally joined by the side joint portion 40. As shown in FIG. However, the tab 30 may be joined to the waist member 20 at a location different from the side joints 40 .
　係合部３２は、左右方向（幅方向）においてサイド接合部４０で接合されている側とは反対側の基材シート３１の端部に設けられている。また、係合部３２は、基材シート３１の肌側面に設けられ、前胴回り部２０ｆの非肌側面と対向し、前胴回り部２０ｆの非肌側面に取り外し可能に係合する部材である。係合部３２としては、非肌側シート２１を構成する繊維に引っ掛かる突起（フック部材）を備えた面ファスナーの雄部材を例示できる。なお、非肌側シート２１の非肌側面に係合部３２が係合しやすい部材（例えば面ファスナーの雌部材）が設けられていてもよい。 The engaging portion 32 is provided at an end portion of the base sheet 31 opposite to the side joined by the side joint portion 40 in the left-right direction (width direction). The engaging portion 32 is provided on the skin side of the base sheet 31, faces the non-skin side of the front waist portion 20f, and is a member that removably engages the non-skin side of the front waist portion 20f. As the engaging portion 32, a male member of a hook-and-loop fastener provided with projections (hook members) that are caught by the fibers forming the non-skin side sheet 21 can be exemplified. The non-skin side surface of the non-skin side sheet 21 may be provided with a member (for example, a female member of a hook-and-loop fastener) with which the engaging portion 32 is easily engaged.

13A and 13B are schematic cross-sectional views of the napkin 1 viewed from the side of the waist opening 1a. FIG. 13A is a diagram of a napkin 1 used in a pants type, and FIG. 13B is a diagram of a napkin 1 used in a tape type. 14 is a developed plan view of the napkin 1 with the front waistline portion 20f separated from the rear waistline portion 20b along the tear line 26. FIG.
　ナプキン１は、パッケージから取り出された初期状態においては、前胴回り部２０ｆ及び後胴回り部２０ｂが環状で繋がれたパンツ型（図１３Ａ）である。そのため、着用者は、ナプキン１をパンツ型のままで着脱することが可能である。 When the napkin 1 is taken out from the package, in the initial state, it is a pants type (Fig. 13A) in which the front waistline portion 20f and the rear waistline portion 20b are connected in a loop. Therefore, the wearer can put on and take off the napkin 1 while it is in the form of pants.
　また、ナプキン１の前胴回り部２０ｆは、左右方向（幅方向）の両側の端部において、上下方向（縦方向）に長さを有する切り取り線２６を有する。そのため、切り取り線２６に沿って前胴回り部２０ｆを上下方向（縦方向）に破り、前胴回り部２０ｆの一部を後胴回り部２０ｂから分離できる。分離後のナプキン１は、図１４に示すように、後胴回り部２０ｂから一対のタブ３０が左右方向（幅方向）の両外側に延出したテープ型となる。そのため、着用者は、ナプキン１をテープ型にして着脱することも可能である。 In addition, the front waist portion 20f of the napkin 1 has perforations 26 having a length in the vertical direction (longitudinal direction) at both ends in the left-right direction (width direction). Therefore, the front waistline portion 20f can be broken in the vertical direction (longitudinal direction) along the perforation line 26 to separate a portion of the front waistline portion 20f from the rear waistline portion 20b. As shown in FIG. 14, the napkin 1 after separation has a tape shape in which a pair of tabs 30 extend outward in the lateral direction (width direction) from the rear waist portion 20b. Therefore, the wearer can put on and take off the napkin 1 in the form of a tape.
　以下の説明では、左右方向（幅方向）の少なくとも片側が後胴回り部２０ｂから分離された前胴回り部２０ｆの部位を「腹側当接部２０ｆＡ」とも呼ぶ。また、後胴回り部２０ｂから分離されずに、サイド接合部４０側に残っている前胴回り部２０ｆの部位を「非分離部２０ｆＢ」とも呼ぶ。 In the following description, the portion of the front waistline portion 20f separated from the rear waistline portion 20b on at least one side in the left-right direction (width direction) is also referred to as the "abdominal contact portion 20fA". A portion of the front waistline portion 20f that remains on the side joint portion 40 side without being separated from the rear waistline portion 20b is also referred to as a "non-separated portion 20fB".
　図１５Ａ～図１５Ｃ、及び、図１６Ａ～図１６Ｄは、着用者がナプキン１を装着する方法の一例を説明する図である。ナプキン１の着用対象者は一般にナプキン１を自分で着脱する。また、着用者は、図１５Ｃ等に示すように不図示の便器等に座った状態、又は立った状態（中腰姿勢の状態）で、ナプキン１を着脱する。 15A to 15C and 16A to 16D are diagrams explaining an example of how the wearer wears the napkin 1. FIG. A person who wears the napkin 1 generally puts on and takes off the napkin 1 by himself/herself. Also, the wearer attaches and detaches the napkin 1 while sitting on a toilet or the like (not shown) as shown in FIG.
　次に、ナプキン１をテープ型で装着する方法の一例を説明する。着用者は、まず、図１５Ａに示すように、パンツ型のナプキン１の左右方向（幅方向）の一方側のタブ３０を左右方向（幅方向）の外側（一方側）に開き、切り取り線２６を露出させる。次に、着用者は、図１５Ｂに示すように、切り取り線２６に沿って前胴回り部２０ｆの左右方向（幅方向）の一方側の端部を上下方向（縦方向）に破り、前胴回り部２０ｆの一部である腹側当接部２０ｆＡを後胴回り部２０ｂから分離する。次に、着用者は、図１５Ｃに示すように、胴回り部材２０の切り離し部分を太腿の前側まで引っ張ってきて、胴回り部材２０を片側の太腿に巻き付ける。そして、図１６Ａに示すように、太腿の上で前胴回り部２０ｆ（腹側当接部２０ｆＡ）の非肌側面にタブ３０（係合部３２）を係合する。なお、図１６Ｂは、図１６Ａのようにナプキン１が巻き付けられた太腿の内側を示す図である。 Next, an example of a method of attaching the napkin 1 with a tape type will be described. First, as shown in FIG. 15A, the wearer opens the tab 30 on one side in the left-right direction (width direction) of the pants-type napkin 1 to the outside (one side) in the left-right direction (width direction), expose the Next, as shown in FIG. 15B, the wearer tears one end of the front waistline portion 20f in the left-right direction (width direction) along the perforation line 26 in the vertical direction (vertical direction) to cut the front waistline portion. A ventral contact portion 20fA, which is a part of 20f, is separated from the rear waist portion 20b. Next, the wearer pulls the cut-off portion of the waist member 20 to the front side of the thigh and wraps the waist member 20 around one thigh, as shown in FIG. 15C. Then, as shown in FIG. 16A, the tab 30 (engagement portion 32) is engaged with the non-skin side surface of the front waist portion 20f (abdominal contact portion 20fA) on the thigh. Note that FIG. 16B is a diagram showing the inside of the thigh around which the napkin 1 is wrapped as in FIG. 16A.
　図１６Ａ及び図１６Ｂの状態では、サイド接合部４０が太腿の上に位置し、吸収性本体１０（吸収性コア１１）が太腿の間で垂れ下がっている。そのため、着用者は、ナプキン１を太腿の周方向に沿って回転する。そうして、図１６Ｃに示すように、サイド接合部４０を自分の脇に位置合わせし、吸収性本体１０を太腿の間に引き上げる。 16A and 16B, the side joints 40 are positioned on the thighs, and the absorbent main body 10 (absorbent core 11) hangs down between the thighs. Therefore, the wearer rotates the napkin 1 along the circumferential direction of the thigh. Then, as shown in FIG. 16C, the side joints 40 are aligned with one's armpits and the absorbent body 10 is pulled up between the thighs.
　次に、着用者は、反対側のタブ３０を左右方向（幅方向）の外側に開いて、反対側においても前胴回り部２０ｆを後胴回り部２０ｂから分離する。それと共に、着用者は、ナプキン１が巻き付けられている太腿側に傾いている吸収性本体１０の傾きを、太腿が延びる方向に沿うように直しながら、太腿の間（着用者の幅方向の中心）に吸収性本体１０を位置合わせする。そして、図１６Ｄに示すように、胴回り部材２０の切り離し部分を太腿の前側まで引っ張ってきて、反対側の太腿にも胴回り部材２０を巻き付けて、太腿の上で前胴回り部２０ｆの非肌側面にタブ３０を係合する。 Next, the wearer opens the tab 30 on the opposite side to the outside in the left-right direction (width direction) to separate the front waistline portion 20f from the rear waistline portion 20b on the other side as well. At the same time, the wearer corrects the inclination of the absorbent main body 10, which is inclined toward the thigh side around which the napkin 1 is wrapped, so as to follow the direction in which the thigh extends. direction center). Then, as shown in FIG. 16D, the cut-off portion of the waist member 20 is pulled to the front side of the thigh, the waist member 20 is wrapped around the opposite thigh, and the front waist member 20f is placed on the thigh. A tab 30 is engaged on the skin side.
　そうすることで、図１３Ｂに示すように、切り取り線２６で分離された前胴回り部２０ｆの腹側当接部２０ｆＡは、一対のタブ３０によって後胴回り部２０ｂと再び環状につながった状態となる。また、着用者の両太腿がナプキン１の一対の脚回り開口１ｂを通った状態となる。最後に、着用者はナプキン１を引き上げて、ナプキン１の装着が完了する。 By doing so, as shown in FIG. 13B, the ventral contact portion 20fA of the front waistline portion 20f separated by the perforation line 26 is again annularly connected to the rear waistline portion 20b by the pair of tabs 30. . Also, both thighs of the wearer pass through the pair of leg openings 1 b of the napkin 1 . Finally, the wearer pulls up the napkin 1 to complete wearing of the napkin 1 .
　このように、本実施形態のナプキン１は、前胴回り部２０ｆの非肌側面に取り外し可能に係合するタブ３０を有する。そのため、着用者は、ナプキン１をテープ型にして使用する場合に、自分の前側においてタブ３０を視認しながら前胴回り部２０ｆにタブ３０を係合できる。よって、着用者が自分でナプキン１を装着する場合の装着性が良い。また、ナプキン１を取り外す場合にも、着用者は自分の前側においてタブ３０を視認しながら前胴回り部２０ｆからタブ３０を取り外すことができる。 Thus, the napkin 1 of this embodiment has the tab 30 that removably engages the non-skin side of the front waist portion 20f. Therefore, when the wearer uses the napkin 1 in a tape shape, the wearer can engage the tab 30 with the front waist portion 20f while visually recognizing the tab 30 on the front side of the wearer. Therefore, the wearability is good when the wearer wears the napkin 1 by himself/herself. Also, when removing the napkin 1, the wearer can remove the tab 30 from the front waist portion 20f while visually recognizing the tab 30 on the front side of the wearer.
　なお、本実施形態のナプキン１では、胴回り部材２０よりも非肌側（外側）にタブ３０が設けられ、タブ３０の肌側面に設けられた係合部３２が、前胴回り部２０ｆの非肌側面に係合する。しかし、これに限定されず、胴回り部材２０の肌側（内側）にタブ３０が設けられ、胴回り部材２０が分離された後に、タブ３０の非肌側面に設けられた係合部３２が、前胴回り部２０ｆの肌側面に係合する形態であってもよい。 In addition, in the napkin 1 of the present embodiment, the tab 30 is provided on the non-skin side (outside) of the waist member 20, and the engaging portion 32 provided on the skin side surface of the tab 30 is attached to the non-skin side of the front waist portion 20f. Engage the sides. However, it is not limited to this, and the tab 30 is provided on the skin side (inner side) of the waist member 20, and after the waist member 20 is separated, the engaging portion 32 provided on the non-skin side of the tab 30 is attached to the front. It may be in a form that engages with the skin side surface of the waist portion 20f.
　また、パンツ型のままでナプキン１を装着した場合、パンツ型のままでナプキン１を脱ぐことも可能であるが、切り取り線２６にて前胴回り部２０ｆを破いてナプキン１を取り外すことも可能である。逆に、テープ型の状態にしてナプキン１を装着した場合に、タブ３０を取り外すことなくナプキン１を脱ぐことも可能である。 In addition, when the napkin 1 is attached while still in the pants shape, it is possible to take off the napkin 1 in the pants shape, but it is also possible to remove the napkin 1 by tearing the front waist portion 20f along the cutting line 26. be. Conversely, when the napkin 1 is attached in a tape-type state, the napkin 1 can be taken off without removing the tab 30 .

　図１７は、パンツ型のナプキン１を前側から見た正面図である。図１７は、左右方向の一方側において前胴回り部２０ｆが後胴回り部２０ｂから分離されたナプキン１の正面図である。なお、図１７では、分離された側のタブ３０は左右方向の内側に閉じられた状態で、前胴回り部２０ｆと後胴回り部２０ｂの間に位置している。図１９は、左右方向の一方側（切り取り線２６）において前胴回り部２０ｆが分離され、タブ３０が外側に開いた状態の後胴回り部２０ｂの一部を示す図である。図２０は、左右方向の両側において前胴回り部２０ｆが後胴回り部２０ｂから分離されたナプキン１の正面図である。 <<<About the napkin 1 of the second embodiment>>>
FIG. 17 is a front view of the underpants-type napkin 1 viewed from the front side. FIG. 17 is a front view of the napkin 1 in which the front waistline portion 20f is separated from the rear waistline portion 20b on one side in the left-right direction. In FIG. 17, the tab 30 on the separated side is positioned between the front waistline portion 20f and the rear waistline portion 20b in a state of being closed inward in the left-right direction. FIG. 19 is a diagram showing a portion of the rear waistline portion 20b with the front waistline portion 20f separated at one side (cut line 26) in the left-right direction and the tab 30 opened outward. FIG. 20 is a front view of the napkin 1 in which the front waistline portion 20f is separated from the rear waistline portion 20b on both sides in the left-right direction.
　ナプキン１は、成人用のパンツ型吸収性物品であるが（初潮を迎えた小中学生も着用対象者に含む）、前胴回り部２０ｆ、及び、サイド接合部４０の上下方向の長さＬ１，Ｌ２が比較的に短い。例えば、介護者にパンツ型吸収性物品を装着してもらう被介護者を着用対象としたパンツ型の使い捨ておむつに比べて、前胴回り部２０ｆの上下方向の長さが短い。 The napkin 1 is a pants-type absorbent article for adults (including elementary and junior high school students who have reached menarche), and the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 in the vertical direction are is relatively short. For example, the length of the front waist portion 20f in the vertical direction is shorter than that of a pants-type disposable diaper that is worn by a cared person to whom a caregiver wears the pants-type absorbent article.
　具体的には、図１７に示すように、サイド接合部４０に接合されたタブ３０が左右方向の内側に閉じられた状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、前胴回り部２０ｆ、及び、サイド接合部４０の上下方向の長さＬ１，Ｌ２を以下とする。まず、左右方向の位置がタブ３０と重複する、前胴回り部２０ｆの部位２０ｆＣの、上下方向の最小長さＬ１を、８０ｍｍ以上１５０ｍｍ以下とする。また、タブ３０が接合されているサイド接合部４０の上下方向の長さＬ２を、１００ｍｍ以上１６０ｍｍ以下とする。 Specifically, as shown in FIG. 17, the tabs 30 joined to the side joints 40 are closed inward in the left-right direction and are engaged with the non-skin side surfaces of the front waistline portion 20f in a natural state. In the napkin 1, the lengths L1 and L2 in the vertical direction of the front waist portion 20f and the side joint portions 40 are set as follows. First, the minimum length L1 in the vertical direction of the portion 20fC of the front waist portion 20f that overlaps the tab 30 in the horizontal direction is set to 80 mm or more and 150 mm or less. Moreover, the vertical length L2 of the side joint portion 40 to which the tab 30 is joined is set to 100 mm or more and 160 mm or less.
　なお、ナプキン１をパッケージから取り出した初期状態が図１７の状態である場合、初期状態、かつ、自然状態のナプキン１にて、測定を行う。初期状態が図１７の状態でない場合（例えばタブ３０が折り畳まれている場合等）は、自然状態のナプキン１（自然状態の胴回り部材２０）に対して、サイド接合部４０から左右方向の内側に向かって広げたタブ３０を前胴回り部２０ｆに係合した状態で、測定を行う。 In addition, when the initial state of the napkin 1 taken out of the package is the state of FIG. 17, the measurement is performed with the napkin 1 in the initial state and the natural state. When the initial state is not the state shown in FIG. 17 (for example, when the tab 30 is folded), the napkin 1 in the natural state (the waist member 20 in the natural state) is positioned inside the side joint 40 in the left-right direction. The measurement is performed with the tab 30, which is spread out, engaged with the front waist portion 20f.
　タブ３０と重なる前胴回り部２０ｆの部位２０ｆＣは、タブ３０を開いて前胴回り部２０ｆを破いた着用者によって、図１５Ｃに示すように把持されやすい部位である。そのため、その部位２０ｆＣの上下方向の長さＬ１を比較的に短くすることで、着用者はその部位２０ｆＣを把持しやすく、太腿の前に前胴回り部２０ｆを引っ張りやすくなる。また、図１６Ｄに示すように、太腿の上の前胴回り部２０ｆを上から手で押さえる際に、前胴回り部２０ｆの上下方向の広範囲を手で押さえることができ、前胴回り部２０ｆの位置が安定した状態でタブ３０を係合できる。 A portion 20fC of the front waist portion 20f that overlaps with the tab 30 is a portion that is likely to be gripped by the wearer who has opened the tab 30 to tear the front waist portion 20f, as shown in FIG. 15C. Therefore, by making the vertical length L1 of the portion 20fC relatively short, the wearer can easily grasp the portion 20fC and pull the front waist portion 20f in front of the thigh. In addition, as shown in FIG. 16D, when the front waist portion 20f on the thigh is pressed from above by the hand, the front waist portion 20f can be pressed over a wide range in the vertical direction, and the position of the front waist portion 20f can be adjusted. can engage the tab 30 in a stable state.
　人工知能研究センターによる日本人の手の寸法データの調査結果によると、親指と人差し指の付け根から、人差し指の先端までの長さの平均値が、女性の場合に１００．６ｍｍであり、男性の場合に１０９.７ｍｍであり、両性（男性及び女性）の場合に１０７ｍｍであった。そのため、前胴回り部２０ｆの上記の寸法Ｌ１を１５０ｍｍ以下とすることで、着用者は、前胴回り部２０ｆの上下方向の半分の長さ以上を把持したり押さえたりすることができる。よって、安定してタブ３０を係合でき、ナプキン１の装着性が向上する。 According to the results of a survey of Japanese hand size data by the Artificial Intelligence Research Center, the average length from the base of the thumb and index finger to the tip of the index finger is 100.6 mm for women and 100.6 mm for men. 109.7 mm for both sexes (male and female) and 107 mm for both sexes. Therefore, by setting the dimension L1 of the front waist portion 20f to 150 mm or less, the wearer can hold or hold the front waist portion 20f for more than half the length in the vertical direction. Therefore, the tab 30 can be stably engaged, and the wearability of the napkin 1 is improved.
　一方で、胴回り部材２０は左右方向に伸縮する部材であり、着用者の胴回りにフィットする。そのため、前胴回り部２０ｆの上記の寸法Ｌ１を８０ｍｍ以上とし、短くし過ぎないことが好ましい。そうすることで、ナプキン１のずれ落ちを防止でき、着用者がナプキン１を安心して利用できる。 On the other hand, the waist member 20 is a member that expands and contracts in the left-right direction and fits the wearer's waist. Therefore, it is preferable that the above-described dimension L1 of the front waist portion 20f is set to 80 mm or more and not too short. By doing so, the napkin 1 can be prevented from slipping down, and the wearer can use the napkin 1 with peace of mind.
　また、サイド接合部４０の上下方向の長さＬ２も、前胴回り部２０ｆと同様に短くすることで、サイド接合部４０に接合されるタブ３０の上下方向の長さも短くなる。よって、図１５Ｃに示すように、着用者がタブ３０を把持しやすくなる。ただし、サイド接合部４０の上下方向の長さＬ２は、前胴回り部２０ｆの上下方向の長さＬ１よりも若干長くなることが好ましく、１００ｍｍ以上１６０ｍｍ以下の範囲とする。そうすることで、図１５Ｃに示すように着用者がタブ３０を持って太腿の下からナプキン１を引き上げる際に、上下方向に長いサイド接合部４０によって、ナプキン１の後方部の上下方向の広範囲に引き上げ力が伝わりやすくなる。よって、太腿の下からナプキン１の後方部を引き上げやすくなる。しかし、これに限定されず、前胴回り部２０ｆとサイド接合部４０の上下方向の長さＬ１，Ｌ２が等しくてもよい。 Also, by shortening the vertical length L2 of the side joints 40 in the same manner as the front waistline portion 20f, the vertical length of the tab 30 joined to the side joints 40 is also shortened. Therefore, as shown in FIG. 15C, it becomes easier for the wearer to grip the tab 30 . However, the vertical length L2 of the side joint portion 40 is preferably slightly longer than the vertical length L1 of the front waist portion 20f, and is in the range of 100 mm or more and 160 mm or less. By doing so, as shown in FIG. 15C , when the wearer holds the tab 30 and pulls up the napkin 1 from under the thigh, the vertically long side joint 40 allows the rear portion of the napkin 1 to move vertically. Pulling force can be easily transmitted over a wide range. Therefore, it becomes easier to pull up the rear part of the napkin 1 from under the thigh. However, it is not limited to this, and the lengths L1 and L2 in the vertical direction of the front waist portion 20f and the side joint portions 40 may be equal.
　このように、前胴回り部２０ｆ及びサイド接合部４０の長さＬ１，Ｌ２を短くすることで、着用者が自分でナプキン１を装着する場合の装着性が向上する。また、自分で装着する着用者を対象とした成人用のパンツ型吸収性物品（例えば本実施形態のナプキン１や軽失禁用のおむつ等）の場合、介護用のパンツ型吸収性物品に比べて、吸収性コア１１が小さく、排泄後の吸収性コア１１も軽い。そのため、前胴回り部２０ｆ及びサイド接合部４０の長さＬ１，Ｌ２を短くしても、パンツ型吸収性物品のずれ落ちの恐れが少ない。 By shortening the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 in this manner, the wearability of the napkin 1 is improved when the wearer wears the napkin 1 by himself/herself. In addition, in the case of an adult pants-type absorbent article for a wearer who wears it by himself (for example, the napkin 1 of the present embodiment, a diaper for light incontinence, etc.), compared to a nursing pants-type absorbent article , the absorbent core 11 is small, and the absorbent core 11 after excretion is also light. Therefore, even if the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 are shortened, the pants-type absorbent article is less likely to slide down.
　さらに、前胴回り部２０ｆ及びサイド接合部４０の長さＬ１，Ｌ２を短くすることで、図１６Ｂに示すように、太腿にナプキン１を巻き付けた際に、ナプキン１（特に吸収性本体１０）が垂れ下がり難くなる。よって、ナプキン１が便器に接触し難く、衛生的に使用できる。また、下着に近い形状となるため、ナプキン１の外観も向上する。 Furthermore, by shortening the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40, as shown in FIG. becomes difficult to hang down. Therefore, the napkin 1 is less likely to come into contact with the toilet and can be used hygienically. Moreover, since the napkin 1 has a shape similar to underwear, the appearance of the napkin 1 is also improved.
　また、ナプキン１が、図１８に示すように、左右方向の一方側のサイド接合部４０の内側端４０ａ（図１７参照）に沿って前胴回り部２０ｆの一部である腹側当接部２０ｆＡが後胴回り部２０ｂから分離された状態、かつ、自然状態であるときに、以下であることが好ましい。まず、左右方向における腹側当接部２０ｆＡの一方側の端Ｐ１から他方側のサイド接合部４０の内側端４０ａまでの長さＷ１は、左右方向における後胴回り部２０ｂの一方側の端Ｐ２から他方側のサイド接合部４０の内側端４０ａまでの長さＷ２よりも長いとよい。つまり、腹側当接部２０ｆＡの左右方向の一方側の端Ｐ１が、後胴回り部２０ｂの左右方向の一方側の端Ｐ２よりも左右方向の一方側（外側）に位置しているとよい。 Further, as shown in FIG. 18, the napkin 1 extends along the inner edge 40a (see FIG. 17) of the side joint portion 40 on one side in the left-right direction. is separated from the rear waist portion 20b and is in a natural state, the following is preferable. First, the length W1 from one end P1 of the abdominal contact portion 20fA in the left-right direction to the inner end 40a of the side joint portion 40 on the other side is equal to the length W1 from one end P2 of the rear waist portion 20b in the left-right direction. It is preferably longer than the length W2 to the inner end 40a of the side joint portion 40 on the other side. That is, it is preferable that one lateral end P1 of the ventral contact portion 20fA is located on one lateral side (outer side) than one lateral end P2 of the rear waist portion 20b.
　そうすることで、着用者がナプキン１を装着するために、胴回り部材２０の左右方向の片側端部を破った際に、腹側当接部２０ｆＡの左右方向の長さＷ１が長くなり、後胴回り部２０ｂの左右方向の長さＷ２が短くなりやすい。着用者がサイド接合部４０にて前胴回り部２０ｆを破った場合には、上記の長さの関係となる。 By doing so, when the wearer tears one end in the left-right direction of the waist member 20 in order to put on the napkin 1, the length W1 in the left-right direction of the ventral contact portion 20fA becomes longer, The lateral length W2 of the waist portion 20b tends to be short. When the wearer breaks the front waistline portion 20f at the side joint portion 40, the length relationship described above is obtained.
　腹側当接部２０ｆＡの左右方向の長さＷ１が長いと、胴回り部材２０を太腿に巻き付ける際に、着用者が腹側当接部２０ｆＡを太腿の前側に引っ張ってきやすくなる。よって、着用者は太腿の上で安定してタブ３０を腹側当接部２０ｆＡに係合でき、ナプキン１の装着性が向上する。一方、後胴回り部２０ｂの左右方向の長さＷ２が短いと、太腿にナプキン１を巻き付けた際に、ナプキン１（吸収性本体１０）が垂れ下がり難く、ナプキン１の便器への接触を抑制できる。 If the length W1 in the left-right direction of the ventral contact portion 20fA is long, the wearer can easily pull the ventral contact portion 20fA to the front side of the thigh when wrapping the waist member 20 around the thigh. Therefore, the wearer can stably engage the tab 30 with the ventral contact portion 20fA on the thigh, and the wearability of the napkin 1 is improved. On the other hand, if the length W2 of the rear waist portion 20b in the left-right direction is short, the napkin 1 (absorbent main body 10) does not easily hang down when the napkin 1 is wrapped around the thigh, and the contact of the napkin 1 with the toilet bowl can be suppressed. .
　また、前胴回り部２０ｆが切り取り線２６を有する場合、切り取り線２６に沿って前胴回り部２０ｆの一部である腹側当接部２０ｆＡが後胴回り部２０ｂから分離された状態、かつ、ナプキン１の自然状態であるときに、以下であることが好ましい。なお、切り取り線２６で分離した状態は図示しないが、図１８のナプキン１において、切り取り線２６よりも左右方向の一方側の前胴回り部２０ｆの部位が分離された状態（視認されない状態）である。上記の状態において、左右方向における腹側当接部２０ｆＡの一方側の端Ｐ３から他方側のサイド接合部４０の内側端４０ａまでの長さＷ３は、左右方向における後胴回り部２０ｂの一方側の端Ｐ２から他方側のサイド接合部４０の内側端４０ａまでの長さＷ２よりも長いとよい。 Further, when the front waistline portion 20f has a cut line 26, the ventral contact portion 20fA, which is a part of the front waistline portion 20f, is separated from the back waistline portion 20b along the cutout line 26, and the napkin 1 When in the natural state of , it is preferable that: Although the state of being separated at the cut line 26 is not shown, in the napkin 1 of FIG. 18, the front waist portion 20 f on one side in the left and right direction from the cut line 26 is separated (not visible). . In the above state, the length W3 from one end P3 of the ventral contact portion 20fA in the left-right direction to the inner end 40a of the side joint portion 40 on the other side is the length of one side of the rear waist portion 20b in the left-right direction. It is preferably longer than the length W2 from the end P2 to the inner end 40a of the side joint portion 40 on the other side.
　そうすることで、着用者が切り取り線２６にて前胴回り部２０ｆを破った場合に、腹側当接部２０ｆＡの左右方向の長さＷ３が長くなり、着用者が胴回り部材２０を太腿に巻き付ける際に、腹側当接部２０ｆＡを・BR>セ腿の前側に引っ張ってきやすくなる。一方、後胴回り部２０ｂの左右方向の長さＷ２が短くなり、太腿にナプキン１を巻き付けた際に、ナプキン１が垂れ下がり難く、ナプキン１の便器への接触を抑制できる。 By doing so, when the wearer breaks the front waist portion 20f at the perforation line 26, the length W3 of the ventral contact portion 20fA in the left-right direction is increased, and the wearer can pull the waist member 20 to the thigh. When wrapping, the ventral contact portion 20fA can be easily pulled toward the front side of the thigh. On the other hand, the length W2 of the rear waist portion 20b in the left-right direction is shortened, and when the napkin 1 is wrapped around the thigh, the napkin 1 does not easily hang down, and the contact of the napkin 1 with the toilet bowl can be suppressed.
　本実施形態のナプキン１では、図１１に示すように、展開かつ伸張状態において、前胴回り部２０ｆと後胴回り部２０ｂの左右方向の長さが同じである。しかし、前胴回り部２０ｆでは、後胴回り部２０ｂに比べて、胴回り弾性部材２４の左右方向の長さが短くなっている。また、前胴回り部２０ｆには、左右方向の中央部の伸縮領域２０ＥＡよりも伸縮性の低い低伸縮領域２０ＮＡ（詳細は後述）が左右方向の両端部に設けられている。そのため、前胴回り部２０ｆの方が後胴回り部２０ｂに比べて、左右方向の収縮力が弱く、自然状態での長さＷ１，Ｗ３（縮み寸法）が短くなる。 In the napkin 1 of this embodiment, as shown in FIG. 11, the front waistline portion 20f and the rear waistline portion 20b have the same length in the left-right direction in the unfolded and stretched state. However, in the front waistline portion 20f, the lateral length of the waistline elastic member 24 is shorter than in the rear waistline portion 20b. In addition, the front waist portion 20f is provided with low-elasticity regions 20NA (details will be described later) having lower elasticity than the central elastic region 20EA in the left-right direction at both ends in the left-right direction. Therefore, compared with the rear waist portion 20b, the front waist portion 20f is weaker in lateral contraction force, and the lengths W1 and W3 (shrinkage dimensions) in the natural state are shorter.
　また、左右方向の一方側の切り取り線２６に沿って前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離され、図１９に示すように、タブ３０が後胴回り部２０ｂから左右方向の外側（一方側）に広げられた状態、かつ、ナプキン１の自然状態における具体的な長さは、以下であることが好ましい。 In addition, the ventral contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b along the cutting line 26 on one side in the left-right direction, and as shown in FIG. It is preferable that the specific length of the napkin 1 in the state of being spread outward (one side) in the direction and in the natural state is as follows.
　まず、図１８に示すように、左右方向における前側の吸収性コア１１の一方側の端１１ａから腹側当接部２０ｆＡの一方側の端Ｐ１までの長さＷ４を、５０ｍｍ以上２００ｍｍ以下にするとよい。そうして、前側の長さＷ４を５０ｍｍ以上と比較的に長くすることで、着用者が胴回り部材２０を太腿に巻き付ける際に、腹側当接部２０ｆＡを太腿の前側に引っ張ってきやすくなる。ただし、前側の長さＷ４を２００ｍｍ以下とし、長くし過ぎないことで、胴回り部材２０が着用者の胴回りにフィットでき、ナプキン１のずれ落ちを抑制できる。 First, as shown in FIG. 18, when the length W4 from one end 11a of the front absorbent core 11 in the left-right direction to one end P1 of the ventral contact portion 20fA is 50 mm or more and 200 mm or less. good. By making the length W4 on the front side relatively long at 50 mm or more, when the wearer wraps the waist member 20 around the thigh, the abdominal contact portion 20fA is easily pulled to the front side of the thigh. Become. However, by setting the length W4 on the front side to 200 mm or less and not making it too long, the waist member 20 can fit around the wearer's waist and the napkin 1 can be prevented from slipping down.
　一方、図１９に示すように、左右方向における後側の吸収性コア１１の一方側の端１１ａから外側に開いたタブ３０の一方側の端までの長さＷ５を、１００ｍｍ以上３００ｍｍ以下にするとよい。そうして、後側の長さＷ５を３００ｍｍ以下と比較的に短くすることで、太腿にナプキン１を巻き付ける際に、外側に開いたタブ３０の便器への接触を抑制できる。ただし、後側の長さＷ５を１００ｍｍ以上とし、短くし過ぎないことで、着用者への胴回り部材２０の締め付けを抑制できる。 On the other hand, as shown in FIG. 19, when the length W5 from the one side end 11a of the rear absorbent core 11 in the left-right direction to the one side end of the tab 30 opened to the outside is 100 mm or more and 300 mm or less. good. Thus, by making the length W5 of the rear side relatively short to 300 mm or less, it is possible to suppress the contact of the tab 30 opened to the outside with the toilet bowl when the napkin 1 is wrapped around the thigh. However, by setting the length W5 on the rear side to 100 mm or more and not making it too short, it is possible to suppress tightening of the waist member 20 on the wearer.
　また、図１１に示すように、展開かつ伸張状態であるパンツ型吸収性物品において、左右方向におけるタブ３０の最大長さＷ６は、２０ｍｍ以上１２０ｍｍ以下であることが好ましい。タブ３０の左右方向の長さＷ６を２０ｍｍ以上とすることで、着用者がタブ３０を前胴回り部２０ｆに係合する際に、タブ３０を持ち易くなる。一方、タブ３０の左右方向の長さＷ６を１２０ｍｍ以下とすることで、太腿にナプキン１を巻き付けた際に、外側に開いたタブ３０の便器への接触を抑制できる。また、タブ３０の左右方向の長さＷ６を長くし過ぎないことで、着用者は、タブ３０を開いて前胴回り部２０ｆを破いた後に、前胴回り部２０ｆに係合部３２を係合しやくなるように係合部３２に近い位置にタブ３０を持ち替える必要がなくなる。 Further, as shown in FIG. 11, in the pants-type absorbent article in the unfolded and stretched state, the maximum length W6 of the tabs 30 in the left-right direction is preferably 20 mm or more and 120 mm or less. By setting the length W6 of the tab 30 in the lateral direction to 20 mm or more, the wearer can easily hold the tab 30 when engaging the tab 30 with the front waist portion 20f. On the other hand, by setting the length W6 of the tab 30 in the lateral direction to 120 mm or less, it is possible to suppress the contact of the tab 30 opened to the outside with the toilet bowl when the napkin 1 is wrapped around the thigh. Also, by not making the length W6 of the tab 30 in the horizontal direction too long, the wearer can engage the engaging portion 32 with the front waist portion 20f after opening the tab 30 and tearing the front waist portion 20f. There is no need to switch the tab 30 to a position closer to the engaging portion 32 so as to make it easier.
　また、図１７に示すように、サイド接合部４０に接合されたタブ３０が左右方向の内側に閉じられた状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、以下であることが好ましい。まず、タブ３０が設けられている側のサイド接合部４０の内側端４０ａの位置における、タブ３０の上下方向の長さＬ３は、同じサイド接合部４０の内側端４０ａの位置における、前胴回り部２０ｆの上下方向の長さＬ１よりも長いことが好ましい。そうすることで、着用者が把持しやすいように前胴回り部２０ｆの上下方向の長さを短くできる。一方で、着用者がタブ３０を持って太腿の下からナプキン１を引き上げる際に、上下方向に長いタブ３０によって、ナプキン１の後方部の上下方向の広範囲に引き上げ力が伝わり、引き上げやすくなる。 Further, as shown in FIG. 17, the napkin 1 in its natural state is engaged with the non-skin side surface of the front waistline portion 20f in a state in which the tabs 30 joined to the side joint portions 40 are closed inward in the left-right direction. In, it is preferable that it is as follows. First, the vertical length L3 of the tab 30 at the position of the inner end 40a of the side joint portion 40 on the side where the tab 30 is provided is the same as the front waistline portion at the position of the inner end 40a of the same side joint portion 40. It is preferably longer than the vertical length L1 of 20f. By doing so, the vertical length of the front waist portion 20f can be shortened so that the wearer can easily grip it. On the other hand, when the wearer holds the tab 30 and pulls up the napkin 1 from under the thigh, the tab 30 that is long in the vertical direction transmits the lifting force over a wide range in the vertical direction at the rear part of the napkin 1, making it easier to pull up. .
　ただし、左右方向の位置が係合部３２と重複する、前胴回り部２０ｆの部位の、上下方向の最小長さＬ４は、係合部３２の上下方向の最大長さＬ５よりも長いことが好ましい。
そうすることで、係合部３２の上下方向の全域を、前胴回り部２０ｆに係合でき、前胴回り部２０ｆにタブ３０をしっかりと係合できる。 However, the minimum vertical length L4 of the portion of the front waistline portion 20f that overlaps the engaging portion 32 in the left-right direction is preferably longer than the maximum vertical length L5 of the engaging portion 32. .
By doing so, the entire vertical region of the engaging portion 32 can be engaged with the front waistline portion 20f, and the tab 30 can be firmly engaged with the front waistline portion 20f.
　また、本実施形態のナプキン１のように、前胴回り部２０ｆは、左右方向の端部において、上下方向に長さを有する切り取り線２６（例えばミシン目）を有することが好ましい。そうすることで、着用者は前胴回り部２０ｆを容易に破ることができる。 Also, like the napkin 1 of the present embodiment, the front waist portion 20f preferably has cut lines 26 (for example, perforations) having length in the vertical direction at the ends in the left-right direction. By doing so, the wearer can easily tear the front waist portion 20f.
　なお、本実施形態の切り取り線２６は、前胴回り部２０ｆの上下方向の全域に設けられているが、切り取り線２６は前胴回り部２０ｆの上下方向の一部に設けられているだけでもよい。また、切り取り線２６は、伸張状態のナプキン１（図１１）に示されるような上下方向に沿う直線形状であるに限らず、上下方向に対して傾斜した直線や曲線形状であってもよい。また、切り取り線２６は、前胴回り部２０ｆを上下方向に破りやすいものであればよく、前胴回り部２０ｆの上端部や下端部に設けられた切欠き部等であってもよい。 Although the perforation line 26 in this embodiment is provided over the entire front waistline portion 20f in the vertical direction, the perforation line 26 may be provided only in a part of the front waistline portion 20f in the vertical direction. Moreover, the perforation line 26 is not limited to a straight line along the vertical direction as shown in the stretched napkin 1 (FIG. 11), but may be a straight line or curved line inclined with respect to the vertical direction. Moreover, the perforation line 26 may be any line that easily breaks the front waistline portion 20f in the vertical direction, and may be a notch portion or the like provided at the upper end portion or the lower end portion of the front waistline portion 20f.
　但し、ナプキン１は切り取り線２６を有していなくてもよい。その場合にも、サイド接合部４０が溶着等によって形成されており、胴回り部材２０の他の領域と比較して剛性が高い。そのため、着用者は、サイド接合部４０の左右方向の内側端４０ａに沿って前胴回り部２０ｆを破ることができる。 However, the napkin 1 may not have the perforation line 26. Also in this case, the side joints 40 are formed by welding or the like, and have higher rigidity than other regions of the waist member 20 . Therefore, the wearer can break the front waist portion 20 f along the lateral inner ends 40 a of the side joints 40 .
　また、本実施形態のナプキン１のように、胴回り部材２０の左右方向の両側に一対のタブ３０が設けられている好ましい。そうすることで、図１５Ｃや図１６Ｄに示すように、胴回り部材２０を両太腿に巻き付けてナプキン１を装着できる。また、ナプキン１を取り外す際には、一対のタブ３０を前胴回り部２０ｆから取り外して、太腿の間からナプキン１を引き抜くことができる。よって、パンツ型のままでナプキン１を着脱する場合のように、ナプキン１の脚回り開口１ｂにつま先を通して着脱する必要がない。ゆえに、着用者がズボンや靴やストッキング等を脱がなくてもナプキン１を着脱でき、外出先でもナプキン１を容易に交換できる。 Also, like the napkin 1 of this embodiment, it is preferable that a pair of tabs 30 are provided on both sides of the waist member 20 in the left-right direction. By doing so, as shown in FIG. 15C and FIG. 16D, the napkin 1 can be worn by wrapping the waist member 20 around both thighs. When removing the napkin 1, the pair of tabs 30 are removed from the front waist portion 20f, and the napkin 1 can be pulled out from between the thighs. Therefore, unlike the case of putting on and taking off the napkin 1 in the form of pants, it is not necessary to pass the toe through the opening 1b around the leg of the napkin 1 to put on and take off. Therefore, the wearer can put on and take off the napkin 1 without taking off pants, shoes, stockings, etc., and can easily replace the napkin 1 on the go.
　また、ナプキン１が左右方向の両側にタブ３０を有する場合、図２０に示すように、左右方向の両側のサイド接合部４０の内側端４０ａに沿って前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離された状態、かつ、自然状態であるときに、以下であるとよい。左右方向における腹側当接部２０ｆＡの一方側の端Ｐ１から他方側の端Ｐ５までの長さＷ７は、左右方向における後胴回り部２０ｂの一方側の端Ｐ２から他方側の端Ｐ６までの長さＷ８よりも長いとよい。つまり、腹側当接部２０ｆＡの左右方向の両端Ｐ１，Ｐ５が、後胴回り部２０ｂの左右方向の両端Ｐ２，Ｐ６よりも左右方向の外側に位置しているとよい。 Further, when the napkin 1 has tabs 30 on both sides in the left-right direction, as shown in FIG. is separated from the rear waist portion 20b and is in a natural state, the following should be satisfied. The length W7 from one end P1 to the other end P5 of the ventral contact portion 20fA in the left-right direction is the length from one end P2 to the other end P6 of the rear waist portion 20b in the left-right direction. It should be longer than W8. In other words, both ends P1 and P5 in the left and right direction of the ventral contact portion 20fA are preferably positioned outside in the left and right direction relative to both ends P2 and P6 in the left and right direction of the rear waist portion 20b.
　そうすることで、片側の太腿だけでなく反対側の太腿に胴回り部材２０を巻き付ける際にも、腹側当接部２０ｆＡを太腿の前側に引っ張ってきやすくなる。一方、それぞれの太腿にナプキン１を巻き付けた際に、ナプキン１が垂れ下がり難く、ナプキン１の便器への接触を抑制できる。 By doing so, it becomes easier to pull the ventral contact portion 20fA to the front side of the thigh when the waist member 20 is wrapped around not only the thigh on one side but also the thigh on the opposite side. On the other hand, when the napkin 1 is wrapped around each thigh, it is difficult for the napkin 1 to hang down, and contact of the napkin 1 with the toilet can be suppressed.
　また、本実施形態のナプキン１のように、係合部３２を１つ有するタブ３０が、ナプキン１の左右方向の両側に１つずつ設けられていることが好ましい。そうすることで、着用者は、タブ３０（係合部３２）を左右方向の両側で１回ずつ係合するだけでよく、容易に装着でき、装着性が向上する。ナプキン１の外観も向上する。また、本実施形態のナプキン１のように、自分で装着する着用者を対象としたパンツ型吸収性物品の場合、介護用のものに比べて吸収性コア１１が小さく、排泄後の吸収性コア１１も軽い。そのため、本実施形態のナプキン１では、介護用のパンツ型吸収性物品のように例えば上下方向に係合部が２つ並んだタブを設けたり、係合部を１つ有するタブを上下方向に２つ並べて、左右方向の両側にタブを２つずつ（２対）設けたりして、タブを前胴回り部２０ｆに強固に固定しなくても、ナプキン１のずれ落ちの恐れが少ない。但し、係合部３２を１つ有するタブ３０が左右方向の両側に１つずつ設けられる形態に限定されない。 Also, like the napkin 1 of the present embodiment, it is preferable that the tabs 30 each having one engaging portion 32 are provided on both sides of the napkin 1 in the left-right direction. By doing so, the wearer only has to engage the tabs 30 (engaging portions 32) once on both sides in the left-right direction, which facilitates wearing and improves wearability. The appearance of the napkin 1 is also improved. In addition, like the napkin 1 of this embodiment, in the case of a pants-type absorbent article intended for a wearer who puts it on by himself, the absorbent core 11 is smaller than that for nursing care, and the absorbent core 11 after excretion is small. 11 is also light. Therefore, in the napkin 1 of the present embodiment, for example, a tab with two engaging portions arranged in the vertical direction is provided like a pants-type absorbent article for nursing care, or a tab having one engaging portion is provided in the vertical direction. Even if two tabs are arranged side by side and two tabs (two pairs) are provided on both sides in the left and right direction, and the tabs are not firmly fixed to the front waist part 20f, the napkin 1 is less likely to slip off. However, the present invention is not limited to the form in which one tab 30 having one engaging portion 32 is provided on each side in the left-right direction.
　また、胴回り部材２０の左右方向の一方側にのみタブ３０が設けられているナプキン１であってもよい。つまり、本実施形態のナプキン１は、少なくとも左右方向の片側をテープ型として使用可能なパンツ型吸収性物品であればよい。その場合も、着用者は、片側の脚のつま先のみを脚回り開口１ｂに通し、もう一方の脚の太腿に胴回り部材２０を巻き付けたり、片側の太腿から胴回り部材２０を取り外し、もう一方の脚のつま先のみを脚回り開口１ｂから抜いたりでき、ナプキン１を着脱しやすくなる。この場合にも、タブ３０が設けられている側の前胴回り部２０ｆの上下方向の長さＬ１を短くしたり、腹側当接部２０ｆＡの左右方向の長さＷ１を短くしたりすることで、着用者の片側の太腿に胴回り部材２０を巻き付ける際の装着性が向上する。 Alternatively, the napkin 1 may have a tab 30 provided only on one side of the waist member 20 in the left-right direction. In other words, the napkin 1 of the present embodiment may be a pants-type absorbent article that can be used as a tape type on at least one side in the left-right direction. Even in that case, the wearer passes only the toe of one leg through the leg opening 1b and wraps the waist member 20 around the thigh of the other leg, or removes the waist member 20 from one thigh and wears the other leg. Only the toe of the leg can be pulled out from the leg opening 1b, and the napkin 1 can be easily attached and detached. Also in this case, by shortening the length L1 in the vertical direction of the front waist portion 20f on the side where the tab 30 is provided, or by shortening the length W1 in the horizontal direction of the ventral contact portion 20fA, , the wearability is improved when the waist member 20 is wrapped around one thigh of the wearer.
　また、図１１に示すように、展開かつ伸張状態であるナプキン１において、上下方向（左右方向に直交する方向であり、吸収性本体１０の長手方向に沿う方向）におけるナプキン１の一方側の端から中心ＣＬまでの長さＬ６が、２００ｍｍ以上３５０ｍｍ以下であることが好ましい。長さＬ６を２００ｍｍ以上とすることで、成人であるナプキン１の着用者のサイズに合わせることができる。一方、長さＬ６を３５０ｍｍ以下とすることで、太腿にナプキン１を巻き付けた際に、ナプキン１が垂れ下がり難く、ナプキン１の便器への接触を抑制できる。 Further, as shown in FIG. 11, in the napkin 1 in the unfolded and stretched state, one end of the napkin 1 in the vertical direction (the direction perpendicular to the left-right direction and along the longitudinal direction of the absorbent body 10) to the center CL is preferably 200 mm or more and 350 mm or less. By setting the length L6 to 200 mm or more, it is possible to match the size of the napkin 1 to an adult wearer. On the other hand, by setting the length L6 to 350 mm or less, when the napkin 1 is wrapped around the thigh, it is difficult for the napkin 1 to hang down, and the contact of the napkin 1 to the toilet bowl can be suppressed.
　また、左右方向の一方側のサイド接合部４０の内側端４０ａ又は切り取り線２６に沿って前胴回り部２０ｆが後胴回り部２０ｂから分離された状態、かつ、ナプキン１の自然状態において、図１８に示すように、腹側当接部２０ｆＡの上端部（Ｐ４）よりも下端部（Ｐ１）の方が、左右方向の一方側（外側）に位置していることが好ましい。 In addition, in a state in which the front waistline portion 20f is separated from the rear waistline portion 20b along the inner edge 40a or the cut line 26 of the side joint portion 40 on one side in the left-right direction, and in the natural state of the napkin 1, as shown in FIG. As shown, the lower end (P1) of the ventral contact portion 20fA is preferably located on one side (outer side) in the left-right direction than the upper end (P4).
　そうすることで、腹側当接部２０ｆＡの切れ端（Ｐ１～Ｐ４）は、胴回り側から股下側に向かって左右方向の外側に傾斜した傾きとなる。そのため、着用者が自分でナプキン１を装着するために、図１５Ｃに示すように胴回り開口１ａ側から腹側当接部２０ｆＡを持つ手の傾く方向と、腹側当接部２０ｆＡの切れ端の傾く方向とが一致する。よって、着用者は腹側当接部２０ｆＡを持ち易くなり、装着性が向上する。 By doing so, the cut ends (P1 to P4) of the ventral contact portion 20fA are slanted outward in the lateral direction from the waist side to the crotch side. Therefore, in order for the wearer to wear the napkin 1 by himself/herself, as shown in FIG. match the direction. Therefore, it becomes easier for the wearer to hold the ventral contact portion 20fA, and wearability is improved.
　本実施形態のナプキン１（図１４参照）では、腹側当接部２０ｆＡの上端部には、伸縮性の肌側シート２２に加えて、胴回り弾性部材２４が設けられている。そのため、腹側当接部２０ｆＡの上端部の方が下端部に比べて収縮力が高く、ナプキン１の自然状態において左右方向の内側に位置する。このように腹側当接部２０ｆＡの上端部の伸縮性を高めることで、着用者の胴回りへのナプキン１のフィット性も高まり、ナプキン１のずれ落ちを抑制できる。 In the napkin 1 (see FIG. 14) of this embodiment, a waist elastic member 24 is provided in addition to the stretchable skin-side sheet 22 at the upper end of the ventral contact portion 20fA. Therefore, the upper end portion of the abdominal contact portion 20fA has a higher contractile force than the lower end portion, and is located inside in the left-right direction when the napkin 1 is in its natural state. By increasing the stretchability of the upper end portion of the ventral contact portion 20fA in this way, the fit of the napkin 1 to the waist of the wearer is also improved, and the slippage of the napkin 1 can be suppressed.
　また、前胴回り部２０ｆ及び後胴回り部２０ｂは、それぞれ、左右方向に伸縮する肌側シート２２，２３、及び、胴回り弾性部材２４を有し、左右方向に伸縮性を有する。図１１や図１４に示すように、前胴回り部２０ｆ及び後胴回り部２０ｂは、少なくとも左右方向の位置が吸収性本体２０と重複する領域において、左右方向に伸縮する伸縮領域２０ＥＡを連続して有することが好ましい。 In addition, the front waist portion 20f and the rear waist portion 20b have skin- side sheets 22 and 23 that stretch in the left-right direction, and waist elastic members 24, respectively, and have stretchability in the left-right direction. As shown in FIGS. 11 and 14, the front waistline portion 20f and the rear waistline portion 20b have a stretchable region 20EA that stretches in the horizontal direction continuously in at least the region where the position in the horizontal direction overlaps with the absorbent main body 20. is preferred.
　そうすることで、ナプキン１が着用者の胴回りにフィットする。特に、ナプキン１がテープ型として使用される場合（図１３Ｂ）、前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離されるが、一対のタブ３０の間で腹側当接部２０ｆＡが左右方向の両外側に引っ張られ、着用者の胴回りにフィットする。また、着用者が胴回り部材２０を太腿に巻き付ける際に、腹側当接部２０ｆＡを太腿の前側に引っ張ってきやすくなり、かつ、ナプキン１の前方部が垂れ下がり難くなる。同様に、後胴回り部２０ｂも着用者の胴回りにフィットでき、かつ、着用者が胴回り部材２０を太腿に巻き付ける際に、ナプキン１の後方部が垂れ下がり難くなる。 By doing so, napkin 1 fits around the wearer's waist. In particular, when the napkin 1 is used as a tape type (FIG. 13B), the ventral contact portion 20fA of the front waistline portion 20f is separated from the back waistline portion 20b, but the ventral contact portion 20fA of the front waistline portion 20f is separated from the back waistline portion 20b. The portion 20fA is pulled outward on both sides in the left-right direction to fit the waist of the wearer. Further, when the wearer wraps the waist member 20 around the thigh, the abdominal contact portion 20fA is easily pulled toward the front of the thigh, and the front portion of the napkin 1 is less likely to hang down. Similarly, the rear waist portion 20b can also fit around the wearer's waist, and when the wearer wraps the waist member 20 around the thigh, the rear portion of the napkin 1 is less likely to hang down.
　ただし、伸縮領域２０ＥＡのうち、吸収性コア１１と厚さ方向に重なる領域では、伸縮力を軽減し、吸収性コア１１の平坦性を確保するようにしてもよい。例えば、吸収性コア１１と厚さ方向に重なる領域では、それ以外の領域に比べて、非肌側シート２１と肌側シート２２，２３の接合部（溶着部）の面積率を高めて、肌側シート２２，２３の弾性特性を抑制するとよい。そうすることで、吸収性コア１１の吸収面積を確保でき、また、吸収性コア１１と着用者の間に隙間が生じてしまうことを防止できる。 However, in the elastic area 20EA, in the area overlapping the absorbent core 11 in the thickness direction, the elastic force may be reduced to ensure the flatness of the absorbent core 11. For example, in the region overlapping the absorbent core 11 in the thickness direction, the area ratio of the joints (welded portions) between the non-skin-side sheet 21 and the skin- side sheets 22 and 23 is increased compared to the other regions, thereby It is preferable to suppress the elastic properties of the side sheets 22 and 23 . By doing so, it is possible to secure the absorbent area of the absorbent core 11 and prevent the occurrence of a gap between the absorbent core 11 and the wearer.
　また、前胴回り部２０ｆは、伸縮領域２０ＥＡよりも左右方向の外側（タブ３０が設けられている側）に、伸縮領域２０ＥＡよりも伸縮性の低い低伸縮領域２０ＮＡを有しているとよい。低伸縮領域２０ＮＡが設けられていることで、着用者が前胴回り部２０ｆを左右方向に引っ張って破る際に、その力が破断部に効率よく伝わり、小さい力で破ることができる。 In addition, the front waist portion 20f preferably has a low stretchable region 20NA having a lower stretchability than the stretchable region 20EA outside the stretchable region 20EA in the left-right direction (on the side where the tab 30 is provided). With the provision of the low-stretch region 20NA, when the wearer pulls the front waist part 20f in the left-right direction to break it, the force is efficiently transmitted to the breaking part, and the front waist part 20f can be broken with a small force.
　そのため、図１１に示すように、ナプキン１が切り取り線２６を有する場合、左右方向における低伸縮領域２０ＮＡの両側端の間に、切り取り線２６が配置されていることが好ましい。そうすることで、切り取り線２６の両外側が伸張し難いため、着用者が切り取り線２６に沿って前胴回り部２０ｆを容易に破ることができる。 Therefore, as shown in FIG. 11, when the napkin 1 has a perforation line 26, it is preferable that the perforation line 26 is arranged between both side ends of the low stretchable region 20NA in the left-right direction. By doing so, the wearer can easily tear the front waist portion 20f along the perforation line 26, since both outer sides of the perforation line 26 are difficult to stretch.
　また、前胴回り部２０ｆが低伸縮領域２０ＮＡにて破られることで、前胴回り部２０ｆの切れ端の保形性が確保されて丸まり難い。つまり、分離される側である腹側当接部２０ｆＡの端部が丸まり難いため、着用者が腹側当接部２０ｆＡを把持しやすく、また、腹側当接部２０ｆＡに安定してタブ３０を係合できる。また、腹側当接部２０ｆＡの端部、及び、サイド接合部４０側に残っている非分離部２０ｆＢが丸まり難いことで、着用者がナプキン１の着用中に前胴回り部２０ｆの切れ端を異物として感じ難く、着け心地が向上する。 In addition, since the front waistline portion 20f is torn at the low-elasticity region 20NA, the cut ends of the front waistline portion 20f are secured in shape retention and are less likely to curl up. That is, since the end of the ventral contact portion 20fA, which is the side to be separated, is less likely to curl, the wearer can easily grip the ventral contact portion 20fA, and the tab 30 can be stably attached to the ventral contact portion 20fA. can engage. In addition, since the end of the abdomen-side contact portion 20fA and the non-separated portion 20fB remaining on the side joint portion 40 side are less likely to curl up, the cut end of the front waist portion 20f can be prevented from becoming foreign matter while the wearer is wearing the napkin 1. It is difficult to feel as it is, and it is more comfortable to wear.
　なお、低伸縮領域２０ＮＡは、伸縮領域２０ＥＡよりも左右方向の伸縮性が低ければよく、伸縮性を有していてもよいし、伸縮性を有していなくてもよい。本実施形態のナプキン１では、低伸縮領域２０ＮＡにも伸縮性の肌側シート２２，２３が配されている。そのため、低伸縮領域２０ＮＡでは、伸縮領域２０ＥＡに比べて、非肌側シート２１と肌側シート２２，２３の接合部（溶着部）の面積率を高めて、肌側シート２２，２３の弾性特性を抑制するとよい。また、図１１に示すように、胴回り弾性部材２４の伸縮部は、低伸縮領域２０ＮＡまで左右方向の外側に延びていないため、これによっても低伸縮領域２０ＮＡの伸縮性が低下する。 It should be noted that the low stretchable region 20NA only needs to have lower stretchability in the horizontal direction than the stretchable region 20EA, and may or may not have stretchability. In the napkin 1 of this embodiment, stretchable skin- side sheets 22 and 23 are also arranged in the low-stretch region 20NA. Therefore, in the low-stretch region 20NA, compared to the stretch region 20EA, the area ratio of the joints (welded portions) between the non-skin-side sheet 21 and the skin- side sheets 22, 23 is increased, and the elastic properties of the skin- side sheets 22, 23 are improved. should be suppressed. Further, as shown in FIG. 11, the stretchable portion of the waist elastic member 24 does not extend outward in the left-right direction to the low stretchable region 20NA, which also reduces the stretchability of the low stretchable region 20NA.
　低伸縮領域２０ＮＡと伸縮領域２０ＥＡの伸縮性（伸縮応力）比較は、ヒトが各領域を引っ張って確認してもよいし、引っ張り試験機（例えば（株）島津製作所製のオートグラフ型引張試験機ＡＧ－１ＫＮ１等）を用いて確認してもよい。例えば、前胴回り部２０ｆから低伸縮領域２０ＮＡと伸縮領域２０ＥＡを切り出し、ナプキン１の左右方向及び縦方向の長さが同じである低伸縮領域（２０ＮＡ）のサンプルと伸縮領域（２０ＥＡ）のサンプルを作製する。そして、ナプキン１の左右方向（伸張方向）に対応するサンプルの両端部をチャックで挟み、サンプルが破断するまでチャック間距離を離してサンプルを伸長する。伸縮領域のサンプルの方が低伸縮領域のサンプルに比べて、サンプルが破断した時のチャック間距離が長いことで、伸縮性が高いことを確認できる。 The elasticity (stretch stress) of the low-stretch region 20NA and the stretch region 20EA may be compared by pulling each region by a human, or by using a tensile tester (for example, an autograph type tensile tester manufactured by Shimadzu Corporation). AG-1KN1, etc.) may be used for confirmation. For example, a low-stretch region 20NA and a stretch region 20EA are cut out from the front waist part 20f, and a sample of the low-stretch region (20NA) and a sample of the stretch region (20EA) having the same length in the horizontal and vertical directions of the napkin 1 are prepared. make. Then, both ends of the sample corresponding to the left-right direction (stretching direction) of the napkin 1 are pinched with chucks, and the sample is stretched with the distance between the chucks separated until the sample breaks. It can be confirmed that the sample in the stretchable region has a higher stretchability than the sample in the low stretchable region because the distance between the chucks when the sample breaks is longer.
　また、図１９に示すように、切り取り線２６に沿って前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離され、タブ３０が左右方向の外側（一方側）に広げられた状態、かつ、ナプキン１の自然状態において、以下であることが好ましい。サイド接合部４０側に残っている前胴回り部２０ｆの非分離部２０ｆＢ（すなわち腹側当接部２０ｆＡから分離された前胴回り部２０ｆの部位）は、係合部３２よりも左右方向の内側に位置していることが好ましい。 Further, as shown in FIG. 19, the ventral contact portion 20fA of the front waistline portion 20f is separated from the rear waistline portion 20b along the cutting line 26, and the tab 30 is spread outward (one side) in the left-right direction. In the state and the natural state of the napkin 1, it is preferable that: The non-separated portion 20fB of the front waistline portion 20f remaining on the side joint portion 40 side (that is, the portion of the front waistline portion 20f separated from the ventral contact portion 20fA) is laterally inward of the engaging portion 32. preferably located.
　そうすることで、前胴回り部２０ｆの非分離部２０ｆＢが係合部３２を覆ってしまうことがなく、タブ３０を係合部３２によって前胴回り部２０ｆの腹側当接部２０ｆＡにしっかりと係合できる。また、タブ３０を腹側当接部２０ｆＡに係合する際に、非分離部２０ｆＢの切れ端の凹凸が腹側当接部２０ｆＡの非肌側面と擦れて、タブ３０や後胴回り部２０ｂに対する腹側当接部２０ｆＡの位置ずれを抑制できる。その結果、タブ３０を腹側当接部２０ｆＡに係合しやすくなり、着用中の位置ずれも抑制できる。 By doing so, the non-separable portion 20fB of the front waist portion 20f does not cover the engaging portion 32, and the tab 30 is firmly engaged with the ventral contact portion 20fA of the front waist portion 20f by the engaging portion 32. can be combined. Further, when the tab 30 is engaged with the ventral contact portion 20fA, the unevenness of the cut end of the non-separable portion 20fB rubs against the non-skin side of the ventral contact portion 20fA, causing the tab 30 and the back waist portion 20b to be separated from each other. Positional deviation of the side contact portion 20fA can be suppressed. As a result, the tab 30 can be easily engaged with the ventral contact portion 20fA, and displacement during wearing can be suppressed.
　さらに、図１１に示すように、展開かつ伸張状態であるナプキン１において、タブ３０が接合されている側（左右方向の一方側）のサイド接合部４０の内側端から切り取り線２６までの左右方向の長さＷ９よりも、切り取り線２６から低伸縮領域２０ＮＡの左右方向の内側（他方側）の端までの長さＷ１０の方が長いことが好ましい。 Furthermore, as shown in FIG. 11, in the napkin 1 in the unfolded and stretched state, the left-right direction from the inner end of the side joint portion 40 on the side where the tab 30 is joined (one side in the left-right direction) to the perforation line 26 It is preferable that the length W10 from the cutoff line 26 to the inner (other side) end in the left-right direction of the low-stretch region 20NA is longer than the length W9.
　そうすることで、前胴回り部２０ｆが切り取り線２６で破られた場合に、サイド接合部４０側に残っている前胴回り部２０ｆの非分離部２０ｆＢの左右方向の長さＷ９’（図１９）よりも、腹側当接部２０ｆＡにおける低伸縮領域２０ＮＡの左右方向の長さＷ１０’の方が長くなる。そのため、タブ３０を腹側当接部２０ｆＡに係合した状態において、サイド接合部４０に残っている非分離部２０ｆＢを、丸まり難い腹側当接部２０ｆＡの端部（低伸縮領域２０ＮＡ）で覆うことができる。よって、非分離部２０ｆＢが着用者の肌に当接し難く、着用中の違和感を軽減できる。また、Ｗ１０を長くすることで、腹側当接部２０ｆＡの丸まり難い端部の長さが長くなり、着用者が腹側当接部２０ｆＡを持ちやすくなり、また、腹側当接部２０ｆＡに安定してタブ３０を係合しやすくなる。 By doing so, when the front waistline portion 20f is torn at the perforation line 26, the left-right direction length W9' of the non-separated portion 20fB of the front waistline portion 20f remaining on the side joint portion 40 side (FIG. 19) The length W10′ in the left-right direction of the low-stretch region 20NA in the ventral contact portion 20fA is longer than that. Therefore, in a state where the tab 30 is engaged with the ventral contact portion 20fA, the non-separated portion 20fB remaining in the side joint portion 40 is moved by the end portion (low stretchable region 20NA) of the ventral contact portion 20fA that is difficult to curl. can be covered. Therefore, the non-separated portion 20fB is less likely to come into contact with the wearer's skin, and discomfort during wearing can be reduced. Further, by lengthening W10, the length of the end portion of the ventral contact portion 20fA that is difficult to roll up is increased, making it easier for the wearer to hold the ventral contact portion 20fA. It becomes easier to stably engage the tab 30 .
　また、胴回り部材２０は左右方向に伸縮性を有するが、剛性の高い吸収性コア１１と厚さ方向に重なる胴回り部材２０の部位では、伸縮性が低下する。前述したように、吸収性コア１１と重なる胴回り部材２０の部位の伸縮性を意図的に抑えてもよい。ただし、吸収性コア１１と重なり伸縮性が低下した胴回り部材２０の部位に、タブ３０の係合部３２を係合した場合、係合部３２が胴回り部材２０の繊維に絡まる度合が小さくなる。 In addition, although the waist member 20 has stretchability in the left-right direction, the stretchability is reduced at a portion of the waist member 20 that overlaps the highly rigid absorbent core 11 in the thickness direction. As described above, the stretchability of the portion of the waist member 20 that overlaps the absorbent core 11 may be intentionally suppressed. However, when the engaging portion 32 of the tab 30 is engaged with the portion of the waist member 20 that overlaps the absorbent core 11 and has reduced stretchability, the degree of entanglement of the engaging portion 32 with the fibers of the waist member 20 is reduced.
　そこで、ナプキン１の展開かつ伸張状態において、前胴回り部２０ｆの上端から吸収性コア１１の前側の上端までの上下方向の長さＬ６（図１４参照）は、係合部３２の上下方向の長さＬ８よりも長いことが好ましい。 Therefore, in the unfolded and stretched state of the napkin 1, the vertical length L6 (see FIG. 14) from the upper end of the front waistline portion 20f to the upper end of the front side of the absorbent core 11 is the length of the engaging portion 32 in the vertical direction. It is preferably longer than L8.
　そうすることで、タブ３０を前胴回り部２０ｆに係合する際に、係合部３２と吸収性コア１１が上下方向にずれやすく、厚さ方向に重なり難い。つまり、吸収性コア１１と厚さ方向に重ならずに伸縮性が低下していない前胴回り部２０ｆの部位に係合部３２が係合されやすい。そのため、係合部３２のフック材が胴回り部材２０の繊維に絡まりやすく、タブ３０の係合強度を高めることができる。 By doing so, when the tab 30 is engaged with the front waistline portion 20f, the engaging portion 32 and the absorbent core 11 are easily displaced in the vertical direction and are unlikely to overlap in the thickness direction. That is, the engaging portion 32 is easily engaged with the portion of the front waistline portion 20f that does not overlap with the absorbent core 11 in the thickness direction and is not stretchable. Therefore, the hook material of the engaging portion 32 is easily entangled with the fibers of the waist member 20, and the engagement strength of the tab 30 can be increased.
　一方で、ナプキン１の展開かつ伸張状態において、後胴回り部２０ｂの上端から吸収性コア１１の後側の上端までの上下方向の長さＬ７（図１４参照）は、係合部３２の上下方向の長さＬ８よりも短いことが好ましい。 On the other hand, in the unfolded and stretched state of the napkin 1, the vertical length L7 (see FIG. 14) from the upper end of the rear waist portion 20b to the rear upper end of the absorbent core 11 is is preferably shorter than the length L8.
　後側の吸収性コア１１が上側に長く延びていることで、後胴回り部２０ｂの上端部の剛性が高まる。よって、着用者が太腿に胴回り部材２０を巻き付ける際に、後胴回り部２０ｂが垂れ下がり難く、ナプキン１の便器への接触を抑制できる。また、排泄物の後ろ漏れも抑制できる。また、タブ３０（係合部３２）は後胴回り部２０ｂには係合されないため、後側の吸収性コア１１が上側に長く延びていても、係合部３２の係合強度が弱くなる問題は生じない。 Since the rear absorbent core 11 extends upward, the rigidity of the upper end of the rear waist portion 20b is increased. Therefore, when the wearer wraps the waist member 20 around the thigh, the rear waist part 20b is less likely to hang down, and the contact of the napkin 1 with the toilet bowl can be suppressed. In addition, back leakage of excrement can be suppressed. In addition, since the tab 30 (engagement portion 32) is not engaged with the rear waist portion 20b, even if the rear absorbent core 11 extends long upward, the engagement strength of the engagement portion 32 is weakened. does not occur.
　また、図１７に示すように、サイド接合部４０に接合されたタブ３０が左右方向の内側に向かって広がった状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、吸収性コア１１よりも左右方向の外側（一方側）に係合部３２が位置していることが好ましい。 Also, as shown in FIG. 17, the napkin in its natural state, in which the tabs 30 joined to the side joints 40 are engaged with the non-skin side surfaces of the front waistline portion 20f in a state where the tabs 30 are spread inward in the left-right direction. 1, it is preferable that the engaging portion 32 is positioned on the outer side (one side) of the absorbent core 11 in the left-right direction.
　そうすることで、吸収性コア１１と厚さ方向に重ならずに伸縮性が低下していない前胴回り部２０ｆの部位に係合部３２が係合されやすい。そのため、係合部３２のフック材が胴回り部材２０の繊維に絡まりやすく、タブ３０の係合強度を高めることができる。 By doing so, the engaging portion 32 is easily engaged with the portion of the front waistline portion 20f that does not overlap with the absorbent core 11 in the thickness direction and does not have reduced stretchability. Therefore, the hook material of the engaging portion 32 is easily entangled with the fibers of the waist member 20, and the engagement strength of the tab 30 can be increased.
　また、タブ３０が左右方向の内側に閉じられた状態において（図１７参照）、タブ３０の上端及び下端の少なくとも一方は（本実施形態では上端及び下端の両方が）、左右方向の内側に向かうにしたがって、タブ３０の上下方向の中心に向かって傾斜した傾斜部３０Ａを有する形状であることが好ましい。つまり、サイド接合部４０で接合されている側とは反対側のタブ３０の自由端部が先細り形状であるとよい。 In addition, when the tab 30 is closed inward in the left-right direction (see FIG. 17), at least one of the upper end and the lower end of the tab 30 (in this embodiment, both the upper end and the lower end) is directed inward in the left-right direction. Accordingly, it is preferable that the tab 30 has a shape having an inclined portion 30A that is inclined toward the center in the vertical direction. In other words, the free end of the tab 30 on the side opposite to the side joined at the side joint 40 is preferably tapered.
　そうすることで、着用者はタブ３０の自由端部（サイド接合部４０に接合されている側とは反対側の端部）を持ち易くなる。また、呼吸時にタブ３０の上端が着用者の腹部と接触し難くなり、脚上げ時にタブ３０の下端が着用者の脚に接触し難くなる。よって、ナプキン１の着用中に、着用者がタブ３０を異物として感じ難く、着け心地が向上する。 By doing so, the wearer can easily hold the free end of the tab 30 (the end opposite to the side joined to the side joint 40). In addition, the upper end of the tab 30 is less likely to come into contact with the wearer's abdomen during breathing, and the lower end of the tab 30 is less likely to come into contact with the wearer's leg when raising the leg. Therefore, the wearer is less likely to feel the tab 30 as a foreign object while wearing the napkin 1, and the wearing comfort is improved.
　また、本実施形態のナプキン１では、前胴回り部２０ｆ（全体）の非肌側面の色と、タブ３０（全体）の非肌側面の色を、同系色とする。例えば、本実施形態のナプキン１とは異なる介護用のおむつでは、白色のタブに青色や緑色の係合部が設けられ、おむつの外側から係合部の色が透けて視認され、前胴回り部とタブとで非肌側面の色が異なっていることが多い。そのため、本実施形態のナプキン１のように、前胴回り部とタブの非肌側面の色を同系色とすることで、おむつらしさが軽減され、ナプキン１の外観が向上する。 Also, in the napkin 1 of the present embodiment, the color of the non-skin side of the front waist portion 20f (whole) and the color of the non-skin side of the tab 30 (whole) are similar colors. For example, in a nursing diaper different from the napkin 1 of the present embodiment, a white tab is provided with a blue or green engaging portion, and the color of the engaging portion can be seen through from the outside of the diaper, and the front waist portion The color of the non-skin side is often different between the tab and the tab. Therefore, like the napkin 1 of this embodiment, by making the color of the front waist part and the non-skin side of the tab similar, the appearance of the napkin 1 is reduced and the appearance of the napkin 1 is improved.
　ただし、上記の場合、着用者がナプキン１の非肌面側から係合部３２の位置を把握し難い。そこで、タブ３０は、係合部３２が配された領域において、タブ３０が厚さ方向に圧搾されている複数の圧搾部３３を有することが好ましい。そうすることで、タブ３０の非肌面側から係合部３２の位置が分かりやすく、タブ３０を前胴回り部２０ｆに係合しやすくなり、ナプキン１の装着性が向上する。なお、圧搾部３３は、タブ３０の肌側から圧搾されていても、非肌側から圧搾されていてもよく、何れの場合にも、タブ３０の外側（非肌側）から圧搾部３３を視認可能となる。 However, in the above case, it is difficult for the wearer to grasp the position of the engaging portion 32 from the non-skin surface side of the napkin 1 . Therefore, it is preferable that the tab 30 has a plurality of compressed portions 33 in which the tab 30 is compressed in the thickness direction in the region where the engaging portion 32 is arranged. By doing so, the position of the engaging portion 32 can be easily recognized from the non-skin surface side of the tab 30, the tab 30 can be easily engaged with the front waist portion 20f, and the wearability of the napkin 1 is improved. The compressed portion 33 may be compressed from the skin side of the tab 30 or from the non-skin side. becomes visible.
　また、係合部３２は、タブ３０を構成する基材シート３１に接着剤にて接合されることが多いが、圧搾部３３によってタブ３０と係合部３２の接合強度がより高まる。そのため、タブ３０から係合部３２が剥がれることなく、タブ３０を付け直すことが可能となる。
また、ナプキン１の着用中にタブ３０が外れてしまうことも防止できる。 Moreover, although the engaging portion 32 is often joined to the base sheet 31 forming the tab 30 with an adhesive, the joining strength between the tab 30 and the engaging portion 32 is further increased by the pressing portion 33 . Therefore, the tab 30 can be reattached without the engaging portion 32 coming off from the tab 30 .
Moreover, it is possible to prevent the tab 30 from coming off while the napkin 1 is being worn.
　ただし、タブ３０に設けられている複数の圧搾部３３の方が、サイド接合部４０に設けられている複数の接合部（例えば不図示の溶着部）よりも、平均ピッチ（上下方向及び左右方向の少なくとも一方向の平均ピッチ）が大きくなるようにするとよい。圧搾部３３の平均ピッチを大きくして、圧搾部３３の面積率を抑えることで、係合部３２のフック材が圧搾部３３で潰れてしまうことを防止できる。一方、サイド接合部４０を構成する接合部の平均ピッチを小さくすることで、サイド接合部４０の接合強度が高まる。よって、ナプキン１の着用時に、着用者がタブ３０を引っ張っても、タブ３０が後胴回り部２０ｂから外れてしまうことを防止できる。 However, the plurality of compressed portions 33 provided on the tab 30 have a higher average pitch (vertical direction and lateral direction) than the plurality of joint portions (for example, welded portions not shown) provided on the side joint portion 40. (average pitch in at least one direction) should be large. By increasing the average pitch of the pressing portions 33 and suppressing the area ratio of the pressing portions 33 , it is possible to prevent the hook members of the engaging portions 32 from being crushed by the pressing portions 33 . On the other hand, by reducing the average pitch of the joints forming the side joints 40, the joint strength of the side joints 40 increases. Therefore, even if the wearer pulls the tab 30 when wearing the napkin 1, it is possible to prevent the tab 30 from coming off the rear waist portion 20b.

　例えば、前述の実施形態では、胴回り部材２０に伸縮性の肌側シート２２，２３が配されることで、胴回り部材２０に左右方向の伸縮性が付与されている。伸縮性のシートの代わりに、左右方向に伸縮する糸状の弾性部材（糸ゴム等）を上下方向に間隔を空けて複数配することで、胴回り部材２０に伸縮性を付与してもよい。 ===Others===
For example, in the above-described embodiment, elastic skin- side sheets 22 and 23 are arranged on the waist member 20, so that the waist member 20 is imparted with elasticity in the left-right direction. Instead of the stretchable sheet, stretchability may be imparted to the waist member 20 by arranging a plurality of thread-like elastic members (such as thread rubber) that stretch in the horizontal direction at intervals in the vertical direction.
　また、タブ３０と重複する前胴回り部２０ｆの上下方向の最小長さＬ１が８０ｍｍ以上１５０ｍｍ以下であり、サイド接合部４０の上下方向の長さＬ２が１００ｍｍ以上１６０ｍｍ以下であることと、サイド接合部４０にて前胴回り部２０ｆを破った場合に、前胴回り部２０ｆの腹側当接部２０ｆＡの方が後胴回り部２０ｂよりも左右方向の長さが長くなること（Ｗ１＞Ｗ２）との両方を満たすに限らず、少なくとも一方を満たすパンツ型吸収性物品であればよい。 In addition, the minimum vertical length L1 of the front waistline portion 20f that overlaps with the tab 30 is 80 mm or more and 150 mm or less, and the vertical length L2 of the side joint portion 40 is 100 mm or more and 160 mm or less; When the front waistline portion 20f is broken at the portion 40, the ventral contact portion 20fA of the front waistline portion 20f is longer in the lateral direction than the rear waistline portion 20b (W1>W2). A pants-type absorbent article that satisfies at least one of them may be used without being limited to satisfying both.
＜＜＜第３実施形態のナプキン１について＞＞＞
　図２１は、切り取り線２６に沿って前胴回り部２０ｆを後胴回り部２０ｂから分離させた状態のナプキン１の展開平面図である。図２２は、パンツ型のナプキン１を前側から見た正面図である。図２３は、係合部３２の縦方向に沿う中心線ＣＬ１が水平となるようにナプキン１を保持した状態の正面図である。図２４は、変形例のナプキン１を図２３と同様に保持した状態の正面図である。 <<<About the napkin 1 of the third embodiment>>>
21 is a developed plan view of the napkin 1 with the front waistline portion 20f separated from the rear waistline portion 20b along the tear line 26. FIG. FIG. 22 is a front view of the underpants-type napkin 1 viewed from the front side. FIG. 23 is a front view of a state in which the napkin 1 is held so that the longitudinal center line CL1 of the engaging portion 32 is horizontal. FIG. 24 is a front view of a modified napkin 1 held in the same manner as in FIG.
　前述したように第３実施形態のナプキン１は、前胴回り部２０ｆに取り外し可能に係合するタブ３０を有する。そのため、着用者は、ナプキン１をテープ型にして使用する場合に、自分の前側においてタブ３０を視認しながら前胴回り部２０ｆにタブ３０を係合できる。よって、着用者が自分でナプキン１を装着する場合の装着性が良い。また、ナプキン１を取り外す場合にも、着用者は自分の前側においてタブ３０を視認しながら前胴回り部２０ｆからタブ３０を取り外すことができる。 As described above, the napkin 1 of the third embodiment has tabs 30 that removably engage with the front waistline portion 20f. Therefore, when the wearer uses the napkin 1 in a tape shape, the wearer can engage the tab 30 with the front waist portion 20f while visually recognizing the tab 30 on the front side of the wearer. Therefore, the wearability is good when the wearer wears the napkin 1 by himself/herself. Also, when removing the napkin 1, the wearer can remove the tab 30 from the front waist portion 20f while visually recognizing the tab 30 on the front side of the wearer.
　なお、本実施形態のナプキン１では、胴回り部材２０よりも非肌側（外側）にタブ３０が設けられ、タブ３０の肌側面に設けられた係合部３２が、前胴回り部２０ｆの非肌側面に係合する。しかし、これに限定されず、胴回り部材２０の肌側（内側）にタブ３０が設けられ、胴回り部材２０が分離された後に、タブ３０の非肌側面に設けられた係合部３２が、前胴回り部２０ｆの肌側面に係合する形態であってもよい。 In addition, in the napkin 1 of the present embodiment, the tab 30 is provided on the non-skin side (outside) of the waist member 20, and the engaging portion 32 provided on the skin side surface of the tab 30 is attached to the non-skin side of the front waist portion 20f. Engage the sides. However, it is not limited to this, and the tab 30 is provided on the skin side (inner side) of the waist member 20, and after the waist member 20 is separated, the engaging portion 32 provided on the non-skin side of the tab 30 is attached to the front. It may be in a form that engages with the skin side surface of the waist portion 20f.
　また、パンツ型のままでナプキン１を装着した場合、パンツ型のままでナプキン１を脱ぐことも可能であるが、切り取り線２６にて前胴回り部２０ｆを破いてナプキン１を取り外すことも可能である。逆に、テープ型の状態にしてナプキン１を装着した場合に、タブ３０を取り外すことなくナプキン１を脱ぐことも可能である。 In addition, when the napkin 1 is attached while still in the pants shape, it is possible to take off the napkin 1 in the pants shape, but it is also possible to remove the napkin 1 by tearing the front waist portion 20f along the cutting line 26. be. Conversely, when the napkin 1 is attached in a tape-type state, the napkin 1 can be taken off without removing the tab 30 .
　また、本実施形態のナプキン１のように、前胴回り部２０ｆは、幅方向の端部において、縦方向に長さを有する切り取り線２６（例えばミシン目）を有することが好ましい。そうすることで、着用者は前胴回り部２０ｆを容易に破ることができる。 Also, like the napkin 1 of this embodiment, the front waist portion 20f preferably has a perforation line 26 (for example, a perforation) having a length in the vertical direction at the end in the width direction. By doing so, the wearer can easily tear the front waist portion 20f.
　なお、本実施形態の切り取り線２６は、前胴回り部２０ｆの縦方向の全域に設けられているが、切り取り線２６は前胴回り部２０ｆの縦方向の一部に設けられているだけでもよい。また、切り取り線２６は、伸張状態のナプキン１（図１１）に示されるような縦方向に沿う直線形状であるに限らず、縦方向に対して傾斜した直線や曲線形状であってもよい。また、切り取り線２６は、前胴回り部２０ｆを縦方向に破りやすいものであればよく、前胴回り部２０ｆの胴回り側の端部や股下側の端部に設けられた切欠き部等であってもよい。 Although the perforation line 26 of the present embodiment is provided over the entire front waistline portion 20f in the longitudinal direction, the perforation line 26 may be provided only in a part of the front waistline portion 20f in the longitudinal direction. Moreover, the perforation line 26 is not limited to a linear shape along the vertical direction as shown in the stretched napkin 1 (FIG. 11), but may be a straight line or curved line inclined with respect to the vertical direction. Also, the perforation line 26 may be any line that can easily tear the front waistline portion 20f in the vertical direction, such as a notch provided at the end of the front waistline portion 20f on the waistline side or the end on the crotch side. good too.
　但し、ナプキン１は切り取り線２６を有していなくてもよい。その場合にも、サイド接合部４０は、溶着等によって形成されており、胴回り部材２０の他の領域と比較して剛性が高い。そのため、着用者は、サイド接合部４０の幅方向の内側端４０ａに沿って前胴回り部２０ｆを破ることができる。 However, the napkin 1 may not have the perforation line 26. Even in this case, the side joints 40 are formed by welding or the like, and have higher rigidity than other regions of the waist member 20 . Therefore, the wearer can tear the front waist portion 20 f along the widthwise inner edge 40 a of the side joint portion 40 .
　また、ナプキン１がパッケージから取り出された初期状態において、ナプキン１の非肌面側（外側）からタブ３０が視認可能であることが好ましい。例えば、本実施形態のナプキン１のように、前胴回り部２０ｆが切り取り線２６を有する場合、切り取り線２６に沿って前胴回り部２０ｆが縦方向に破られていない状態において、前胴回り部２０ｆの非肌面側からタブ３０が視認可能であることが好ましい。 In addition, it is preferable that the tab 30 is visible from the non-skin surface side (outside) of the napkin 1 in the initial state after the napkin 1 is taken out of the package. For example, when the front waistline portion 20f has the perforation line 26, as in the napkin 1 of the present embodiment, the front waistline portion 20f is not torn in the vertical direction along the perforation line 26. It is preferable that the tab 30 is visible from the non-skin side.
　そうすることで、ナプキン１がパンツ型としてもテープ型としても使用可能であることを着用者が認識しやすくなる。よって、ナプキン１の着用者は、その時の状況に応じて、ナプキン１をパンツ型のままで着脱したり、テープ型にして着脱したりすることができ、ナプキン１の着脱しやすさが向上する。 By doing so, it becomes easier for the wearer to recognize that the napkin 1 can be used as either a pants type or a tape type. Therefore, the wearer of the napkin 1 can put on and take off the napkin 1 as it is in a pants shape or in a tape shape according to the situation at that time, and the easiness of putting on and taking off the napkin 1 is improved. .
　また、着用者がナプキン１をテープ型にして自分で装着する場合、図１５Ｃや図１６Ａに示すように、切り取り線２６等で切り離した胴回り部材２０を太腿に巻き付けつつ、太腿の上でタブ３０を係合する方法が想定される。そうすることで、前胴回り部２０ｆにタブ３０（係合部３２）を安定して係合できる。 In addition, when the wearer wears the napkin 1 in a tape shape and wears it by himself, as shown in FIGS. Methods of engaging tab 30 are envisioned. By doing so, the tab 30 (engaging portion 32) can be stably engaged with the front waist portion 20f.
　ただし、着用者が、便器に座った状態、或いは、便器の近くにおいて中腰で立った状態で、片側の太腿にナプキン１を巻き付けた状態では、図１６Ｂに示すようにナプキン１が垂れ下がりやすい。特に、ナプキン１の重さの大部分を占める吸収性コア１１が太腿から垂れ下がりやすい。太腿から垂れ下がったナプキン１の部位が便器に接触してしまうと、これから着用するナプキン１の衛生状態が低下してしまう。 However, when the wearer is sitting on the toilet or standing half-assed near the toilet and the napkin 1 is wrapped around one thigh, the napkin 1 tends to hang down as shown in FIG. 16B. In particular, the absorbent core 11, which accounts for most of the weight of the napkin 1, tends to hang down from the thighs. If the portion of the napkin 1 hanging down from the thigh comes into contact with the toilet bowl, the sanitary condition of the napkin 1 to be worn from now on will be deteriorated.
　そこで、本実施形態のナプキン１では、タブ３０が備える係合部３２の縦方向の胴回り側（一方側）の端の幅方向の中心３２ａと、係合部３２の縦方向の股下側（他方側）の端の幅方向の中心３２ｂと、を繋ぐ中心線ＣＬ１（図２１，図２２参照）が水平となるように、ナプキン１を保持したときに（図２３）、吸収性コア１１の最下端１１Ｌを、ナプキン１（製品）の最下端１Ｌよりも上側に位置させる。 Therefore, in the napkin 1 of the present embodiment, the center 32a in the width direction of the end of the engagement portion 32 provided in the tab 30 on the waist side (one side) in the vertical direction and the crotch side (the other side) in the vertical direction of the engagement portion 32 When the napkin 1 is held so that the center line CL1 (see FIGS. 21 and 22) connecting the center 32b in the width direction of the edge of the side) is horizontal (FIG. 23), the maximum of the absorbent core 11 The bottom end 11L is positioned above the bottom end 1L of the napkin 1 (product).
　図２３のようにナプキン１が太腿に巻き付けられた状態に近い状態において、ナプキン１の重さの大部分を占める吸収性コア１１がナプキン１の最下端よりも上側に位置しているということは、吸収性コア１１の最下端が製品の最下端となる場合に比べて、吸収性コア１１が垂れ下がっていないといえる。よって、胴回り部材２０が太腿に巻き付けられた際に（図１６Ｂ）、ナプキン１の便器への接触を抑制できる。 In a state in which the napkin 1 is wrapped around the thigh as shown in FIG. can be said that the absorbent core 11 does not hang down as compared with the case where the lowest end of the absorbent core 11 becomes the lowest end of the product. Therefore, when the waist member 20 is wrapped around the thigh (FIG. 16B), the contact of the napkin 1 with the toilet bowl can be suppressed.
　その結果、ナプキン１の衛生状態を良好に保つことができる。また、ナプキン１が便器に接触し難いことで、着用者は太腿に胴回り部材２０を巻き付ける動作に集中でき、ナプキン１の装着性が向上する。また、着用者は、前胴回り部２０ｆにタブ３０を係合した後に、ナプキン１を太腿の周方向に沿って回転し、図１６Ｃに示すように吸収性コア１１（吸収性本体１０）を太腿の間に引き上げる。そのため、吸収性コア１１の垂れ下がりが少ないことで、吸収性コア１１の引き上げ動作も容易となる。 As a result, the sanitary condition of the napkin 1 can be maintained in good condition. In addition, since the napkin 1 is less likely to come into contact with the toilet bowl, the wearer can concentrate on the operation of wrapping the waist member 20 around the thigh, and the wearability of the napkin 1 is improved. Further, after engaging the tab 30 with the front waist portion 20f, the wearer rotates the napkin 1 along the circumferential direction of the thigh, and as shown in FIG. 16C, the absorbent core 11 (absorbent main body 10) Pull it up between your thighs. Therefore, since the absorbent core 11 is less likely to hang down, the operation of pulling up the absorbent core 11 is facilitated.
　なお、胴回り部材２０が切り取り線２６等で分離されていないパンツ型のままのナプキン１を、図２３のように保持して観察する。また、パッケージから取り出した初期状態のタブ３０における係合部３２の中心線ＣＬ１が水平となるように、ナプキン１を保持する。本実施形態のナプキン１では、パッケージから取り出した初期状態が図２２の状態とする。ゆえに、タブ３０が胴回り部材２０に接合された位置（サイド接合部４０）から幅方向の内側に向かって広げられた状態で前胴回り部２０ｆに係合しており、そのタブ３０の位置における係合部３２の中心線ＣＬ１が水平となるように、ナプキン１を保持する。一方、パッケージから取り出した初期状態が図２２の状態ではなく、例えばタブ３０（係合部３２）が折り畳まれている場合は、その折り畳まれているタブ３０の位置における係合部３２の中心線ＣＬ１（係合部３２も折り畳まれている場合には折り畳まれている状態での係合部３２の中心線ＣＬ１）が水平となるようにナプキン１を保持する。 The pant-shaped napkin 1 in which the waist member 20 is not separated by the perforation line 26 or the like is held and observed as shown in FIG. Further, the napkin 1 is held so that the center line CL1 of the engaging portion 32 of the tab 30 in the initial state taken out of the package is horizontal. The napkin 1 of this embodiment is in the state shown in FIG. 22 when it is taken out from the package. Therefore, the tab 30 is engaged with the front waistline portion 20f in a state of being expanded inward in the width direction from the position (side joint portion 40) where the tab 30 is joined to the waistline member 20, and the engagement at the position of the tab 30 is prevented. The napkin 1 is held so that the center line CL1 of the joining portion 32 is horizontal. On the other hand, if the initial state taken out of the package is not the state shown in FIG. The napkin 1 is held so that CL1 (the center line CL1 of the folded engaging portion 32 when the engaging portion 32 is also folded) is horizontal.
　また、係合部３２の中心線ＣＬ１が水平となるようにナプキン１を保持するために、ＪＩＳ１級に準拠した金尺定規（例えばシンワ測定社製の直尺シルバー（長さ３３５ｍｍ又は５００ｍｍ、幅２５ｍｍ、厚み１ｍｍ）、或いはそれと同等のもの）を用いて測定する。具体的には、まず、水平な作業台５０の面に定規５１の平面を沿わせて、作業台５０から定規５１を２００ｍｍ突出させる。次に、定規５１に、ナプキン１の脚回り開口１ｂ及び胴回り開口１ａを通す。そして、突出した定規５１の端から５０ｍｍ内側（作業台５０側）の位置に、ナプキン１の胴回り開口端を合わせる。また、定規５１の幅（２５ｍｍ）の中心位置に、ナプキン１の係合部３２の縦方向の中心線ＣＬ１を合わせる。そうして、定規５１から垂れ下がったナプキン１の状態を観察する（例えば吸収性コア１１とナプキン１の最下端の位置を比較する）。なお、両面テープ等を用いて、作業台５０と定規５１を固定したり、定規５１とナプキン１を固定したりするとよい。また、パンツ型吸収性物品の重さで定規５１が撓む場合には、定規５１をその厚さ方向に２～３枚重ねてパンツ型吸収性物品を保持するようにしてもよい。又は、作業台５０から突出する定規５１の長さを短くしてもよい。以下の測定や比較も同様に行うものとする。また、図２３の状態のナプキン１の測定や比較は、実際のナプキン１にて行ってもよいし、図２３の状態のナプキン１を前側から撮影した画像に基づいて行ってもよい。 In addition, in order to hold the napkin 1 so that the center line CL1 of the engaging portion 32 is horizontal, a metal ruler conforming to JIS Class 1 (for example, a straight silver ruler manufactured by Shinwa Measurement Co., Ltd. (length 335 mm or 500 mm, width 25 mm, 1 mm thick), or equivalent). Specifically, first, the plane of the ruler 51 is aligned with the horizontal surface of the workbench 50, and the ruler 51 is protruded from the workbench 50 by 200 mm. Next, the ruler 51 is passed through the leg opening 1b and the waist opening 1a of the napkin 1 . Then, the open end of the waistline of the napkin 1 is aligned with the position 50 mm inside (on the workbench 50 side) from the protruding end of the ruler 51 . Also, the vertical center line CL1 of the engaging portion 32 of the napkin 1 is aligned with the central position of the width (25 mm) of the ruler 51 . Then, observe the state of the napkin 1 hanging from the ruler 51 (for example, compare the position of the lowest end of the absorbent core 11 and the napkin 1). Note that it is preferable to fix the work table 50 and the ruler 51 or the ruler 51 and the napkin 1 using double-sided tape or the like. Also, if the ruler 51 bends due to the weight of the pants-type absorbent article, two or three rulers 51 may be stacked in the thickness direction to hold the pants-type absorbent article. Alternatively, the length of the ruler 51 protruding from the workbench 50 may be shortened. The following measurements and comparisons shall be made in the same way. Moreover, the measurement and comparison of the napkin 1 in the state of FIG. 23 may be performed with the actual napkin 1, or may be performed based on the image of the napkin 1 in the state of FIG. 23 photographed from the front side.
　また、以下の説明では、ナプキン１の２つ折り部Ｆ（縦方向における股下側の端）よりも前側に位置する吸収性コア１１の部位を「前側の吸収性コア１１Ｆ」とも呼び、２つ折り部Ｆよりも後側に位置する吸収性コア１１の部位を「後側の吸収性コア１１Ｂ」とも呼ぶ。同様に、ナプキン１の２つ折り部Ｆよりも前側に位置する吸収性本体１０の部位を「前側の吸収性本体１０Ｆ」とも呼び、２つ折り部Ｆよりも後側に位置する吸収性本体１０の部位を「後側の吸収性本体１０Ｂ」とも呼ぶ。 In addition, in the following description, the portion of the absorbent core 11 located on the front side of the two-folded portion F (end of the crotch side in the longitudinal direction) of the napkin 1 is also referred to as the “front-side absorbent core 11F”, and the two-folded portion The portion of the absorbent core 11 located on the rear side of F is also referred to as "the rear absorbent core 11B". Similarly, the portion of the absorbent body 10 located on the front side of the two-folded portion F of the napkin 1 is also referred to as the "front-side absorbent body 10F", and the portion of the absorbent body 10 located on the rear side of the two-folded portion F. The part is also called "back absorbent main body 10B".
　また、本実施形態のナプキン１では、係合部３２の中心線ＣＬ１が水平となるようにナプキン１を保持したときに（図２３）、以下であるとする。まず、前側の吸収性コア１１Ｆが有する幅方向の両側端のうち上側に位置する側端１１ＳＵと、ナプキン１の２つ折り部Ｆとが、交差する点Ｐ１を通る水平ラインＬＨ（鉛直方向における水平位置）を特定する。その水平ラインＬＨからナプキン１の最下端１Ｌまでの、鉛直方向（上下方向）の長さＬ４の方が、水平ラインＬＨからナプキンの最上端１Ｕ（すなわち定規５１の上面）までの鉛直方向の長さＬ３よりも短い。 Further, in the napkin 1 of the present embodiment, when the napkin 1 is held so that the center line CL1 of the engaging portion 32 is horizontal (Fig. 23), the following conditions are assumed. First, a horizontal line LH (a horizontal line in the vertical direction) passing through a point P1 where the upper side end 11SU of the width direction side ends of the front absorbent core 11F and the two-folded portion F of the napkin 1 intersect. location). The vertical (vertical) length L4 from the horizontal line LH to the lowermost edge 1L of the napkin 1 is the vertical length from the horizontal line LH to the uppermost edge 1U of the napkin (that is, the upper surface of the ruler 51). shorter than L3.
　水平ラインＬＨの位置は、胴回り部材２０が巻き付けられた太腿の下面の位置に概ね相当する。そのため、上記のように水平ラインＬＨからナプキン１の最下端１Ｌまでの鉛直方向の長さＬ４を短くすることで、太腿に胴回り部材２０が巻き付けられた際のナプキン１の垂れ下がり量を少なくできる。具体的には、図２３のように保持されたナプキン１において、吸収性コアの最下端が製品の最下端となる吸収性物品に比べて、長さＬ４を短くでき、太腿に胴回り部材２０が巻き付けられた際のナプキン１の垂れ下がり量を少なくできる。よって、ナプキン１の便器への接触を抑制できる。 The position of the horizontal line LH generally corresponds to the position of the lower surface of the thigh around which the waist member 20 is wrapped. Therefore, by shortening the vertical length L4 from the horizontal line LH to the lowermost end 1L of the napkin 1 as described above, it is possible to reduce the hanging amount of the napkin 1 when the waist member 20 is wrapped around the thigh. . Specifically, in the napkin 1 held as shown in FIG. 23, the length L4 can be shortened compared to the absorbent article in which the lowest end of the absorbent core is the lowest end of the product, and the waist member 20 is attached to the thigh. can reduce the hanging amount of the napkin 1 when it is wound. Therefore, the contact of the napkin 1 with the toilet bowl can be suppressed.
　なお、上記の長さＬ３，Ｌ４の測定方法としては、以下の方法が挙げられる。まず、図２２に示す自然状態のナプキン１（例えば水平な台に平置きされた無負荷状態のナプキン１）の前側の非肌側面にペンで印を付ける。すなわち、ナプキン１の２つ折り部Ｆと、水平に係合部３２が保持される側の吸収性コア１１の側端１１ＳＵとの交点Ｐ１の位置に印をつける。次に、図２３の状態のナプキン１に対して、交点Ｐ１を通る水平ラインＬＨをペンで印す。そして、水平ラインＬＨからのナプキン１の最上端１Ｕ及び最下端１Ｌまでの
長さＬ３，Ｌ４を定規等で測定する。或いは、図２３の状態のナプキン１を前側から撮影した画像データ上において水平ラインＬＨを特定し、長さＬ３，Ｌ４の比較を行ってもよい。 In addition, the following methods are mentioned as a measuring method of said length L3, L4. First, the front non-skin side of the napkin 1 in the natural state shown in FIG. 22 (for example, the napkin 1 in an unloaded state laid flat on a horizontal table) is marked with a pen. That is, the position of the intersection point P1 between the folded portion F of the napkin 1 and the side end 11SU of the absorbent core 11 on the side where the engaging portion 32 is held horizontally is marked. Next, on the napkin 1 in the state of FIG. 23, a horizontal line LH passing through the intersection point P1 is marked with a pen. Then, lengths L3 and L4 from the horizontal line LH to the top end 1U and the bottom end 1L of the napkin 1 are measured with a ruler or the like. Alternatively, the horizontal line LH may be specified on the image data obtained by photographing the napkin 1 in the state of FIG. 23 from the front side, and the lengths L3 and L4 may be compared.
　また、自然状態のナプキン１（図２２）において、前側の吸収性本体１０Ｆは、縦方向の胴回り側（一方側）の端の幅方向の中心である第１中心Ｃ１と、前側の吸収性本体１０Ｆを縦方向に二分する中央線の幅方向の中心である第２中心Ｃ２と、縦方向の股下側（他方側）の端の幅方向の中心である第３中心Ｃ３を有する。 In addition, in the napkin 1 (FIG. 22) in the natural state, the front absorbent main body 10F has a first center C1, which is the center in the width direction of the end of the vertical waist side (one side), and the front absorbent main body. It has a second center C2 that is the center in the width direction of the center line that bisects 10F in the lengthwise direction, and a third center C3 that is the center in the width direction of the end on the crotch side (the other side) in the lengthwise direction.
　本実施形態のナプキン１では、係合部３２の中心線ＣＬ１が水平となるようにナプキン１を保持したときに（図２３）、第１中心Ｃ１と第２中心Ｃ２を繋ぐ線Ｌａの水平方向に対する傾きと、第２中心Ｃ２と第３中心Ｃ３を繋ぐ線Ｌｂの水平方向に対する傾きとが、同一である。なお、線Ｌａ，線Ｌｂの水平方向に対する傾きが同一であるとは、実質的に同一であればよく、０～５度以下程度の傾きの誤差が生じる場合も同一とする。 In the napkin 1 of the present embodiment, when the napkin 1 is held so that the center line CL1 of the engaging portion 32 is horizontal (FIG. 23), the horizontal direction of the line La connecting the first center C1 and the second center C2 and the inclination of the line Lb connecting the second center C2 and the third center C3 with respect to the horizontal direction. It should be noted that the line La and the line Lb having the same slope with respect to the horizontal direction only need to be substantially the same, and even if there is an error in the slope of about 0 to 5 degrees or less, it is the same.
　線Ｌａ及び線Ｌｂの水平方向に対する傾きが同一であり、線Ｌａ及び線Ｌｂが同一線上に位置するということは、吸収性本体１０の縦方向における胴回り側の部位（Ｃ１～Ｃ２の範囲の部位）に対して、股下側の部位（Ｃ２～Ｃ３の範囲の部位）が傾いていないということである。つまり、ナプキン１が図２３の状態であっても、吸収性本体１０が縦方向の途中で折れることなく、吸収性本体１０の股下側の部位が垂れ下がっていないということである。よって、胴回り部材２０が太腿に巻き付けられた際に、ナプキン１の便器への接触を抑制できる。 The fact that the line La and the line Lb have the same inclination with respect to the horizontal direction and that the line La and the line Lb are located on the same line means that the portion on the waist side in the vertical direction of the absorbent body 10 (the portion in the range of C1 to C2 ), the part on the crotch side (the part in the range of C2 to C3) is not inclined. In other words, even when the napkin 1 is in the state shown in FIG. 23, the absorbent main body 10 does not fold in the middle of the vertical direction, and the crotch side portion of the absorbent main body 10 does not hang down. Therefore, when the waist member 20 is wrapped around the thigh, the contact of the napkin 1 with the toilet bowl can be suppressed.
　なお、線Ｌａ，線Ｌｂの傾きの確認方法としては、以下の方法が挙げられる。まず、図２２に示す自然状態のナプキン１の前側の非肌側面に対して、第１中心Ｃ１～第３中心Ｃ３の位置にペンで印を付ける。次に、図２３の状態のナプキン１に対して、第１中心Ｃ１と第２中心Ｃ２を繋ぐ線Ｌａと、第２中心Ｃ２と第３中心Ｃ３を繋ぐ線Ｌｂをペンで印す。そして、線Ｌａと線Ｌｂの水平方向に対する傾きを、定規等を用いて確認する。或いは、図２３の状態のナプキン１を前側から撮影した画像データ上において、線Ｌａと線Ｌｂを特定して傾きを比較してもよい。 It should be noted that the following method can be used to confirm the inclination of the lines La and Lb. First, positions of the first center C1 to the third center C3 are marked with a pen on the front non-skin side of the napkin 1 in the natural state shown in FIG. Next, a line La connecting the first center C1 and the second center C2 and a line Lb connecting the second center C2 and the third center C3 are marked with a pen on the napkin 1 in the state of FIG. Then, the inclination of the lines La and Lb with respect to the horizontal direction is confirmed using a ruler or the like. Alternatively, on the image data obtained by photographing the napkin 1 in the state of FIG. 23 from the front side, the line La and the line Lb may be specified and the inclinations thereof may be compared.
　また、係合部３２の中心線ＣＬ１が水平となるように保持されたナプキン１を前側から視認したときに、図２３に示すように、幅方向における吸収性本体１０の一対の側端のうちの下側の側端１０ＳＬよりも下側に（すなわち下側の脚回り開口１ｂから）、後側の吸収性本体１０の肌側面が視認されるとよい。例えば、前胴回り部２０ｆの幅方向の内側の位置にタブ３０が係合されるようにしたり、後胴回り部２０ｂの幅方向の伸縮性を低くしたりする。 Further, when the napkin 1 held so that the center line CL1 of the engaging portion 32 is horizontal is viewed from the front side, as shown in FIG. It is preferable that the skin side surface of the absorbent body 10 on the rear side is visible below the lower side end 10SL (that is, from the leg opening 1b on the lower side). For example, the tab 30 is engaged with the widthwise inner position of the front waistline portion 20f, or the widthwise stretchability of the rear waistline portion 20b is reduced.
　そうすることで、胴回り部材２０が太腿に巻き付けられた際に、前側の吸収性本体１０Ｆが上側に位置するため、ナプキン１を太腿の周方向に沿って回転し、太腿の間に吸収性本体１０を引き上げる動作が容易となる。つまり、着用者が、前側の吸収性本体１０Ｆの幅方向の両側部を持って引き上げる量が少なくなり、次の動作に移行しやすくなる。 By doing so, when the waist member 20 is wrapped around the thigh, the absorbent body 10F on the front side is positioned on the upper side, so that the napkin 1 is rotated along the circumferential direction of the thigh and between the thighs. The operation of pulling up the absorbent main body 10 is facilitated. In other words, the amount that the wearer pulls up by holding both sides of the front absorbent main body 10F in the width direction is reduced, making it easier to move to the next operation.
　しかし、図２３とは逆に、図２４の変形例に示すように、係合部３２の中心線ＣＬ１が水平となるように保持されたナプキン１を前側から視認したときに、幅方向における吸収性本体１０の一対の側端のうちの上側の側端１０ＳＵよりも上側に（すなわち上側の脚回り開口１ｂから）、後側の吸収性本体１０Ｂの肌側面が視認されるようにしてもよい。例えば、前胴回り部２０ｆの幅方向の外側の位置にタブ３０が係合されるようにしたり、後胴回り部２０ｂの幅方向の伸縮性を高くしたりする。 However, contrary to FIG. 23, as shown in the modified example of FIG. 24, when the napkin 1 held so that the center line CL1 of the engaging portion 32 is horizontal is viewed from the front side, the absorption in the width direction The skin side of the absorbent main body 10B on the rear side may be visible above the upper side end 10SU of the pair of side edges of the absorbent main body 10 (that is, from the upper leg opening 1b). . For example, the tab 30 is engaged with the widthwise outer position of the front waistline portion 20f, or the widthwise stretchability of the rear waistline portion 20b is increased.
　胴回り部材２０が太腿に巻き付けられる際に、ナプキン１の後方部は、前方部に比べて便器の近くに位置しやすく、また、太腿の下を通されて巻き付けられる。そのため、上記のように後側の吸収性本体１０Ｂを上側に位置させることで、ナプキン１の後方部の便器への接触をより抑制できる。 When the waist member 20 is wrapped around the thigh, the rear part of the napkin 1 is more likely to be positioned closer to the toilet bowl than the front part, and is wrapped under the thigh. Therefore, by locating the rear absorbent main body 10B on the upper side as described above, the contact of the rear portion of the napkin 1 with the toilet bowl can be further suppressed.
　また、図２４の場合、図２３の場合に比べて、水平方向に対する前側の吸収性本体１０Ｆの傾きが小さい。そのため、着用者が太腿の間に前側の吸収性本体１０Ｆを引き上げた際に（図１６Ｃ）、太腿が延びる方向に対する前側の吸収性本体１０Ｆの傾きが小さく、前側の吸収性本体１０Ｆを位置合わせする動作が容易となる。 Also, in the case of FIG. 24, the inclination of the front absorbent main body 10F with respect to the horizontal direction is smaller than in the case of FIG. Therefore, when the wearer pulls up the front absorbent main body 10F between the thighs (FIG. 16C), the inclination of the front absorbent main body 10F with respect to the direction in which the thigh extends is small, and the front absorbent main body 10F is pulled up. Alignment operation is facilitated.
　さらに、係合部３２の中心線ＣＬ１が水平となるようにナプキン１を保持したときに（図２３）、その係合部３２（３２Ａ）とは幅方向の反対側の位置に設けられている下側のタブ３０（他の係合部材）の係合部３２（３２Ｂ）が、ナプキン１の最下端１Ｌよりも上側に位置しているとよい。 Furthermore, when the napkin 1 is held so that the center line CL1 of the engaging portion 32 is horizontal (FIG. 23), the engaging portion 32 (32A) is provided at the opposite side in the width direction. The engaging portion 32 (32B) of the lower tab 30 (another engaging member) is preferably located above the lowermost end 1L of the napkin 1. As shown in FIG.
　そうすることで、着用者が胴回り部材２０を太腿に巻き付けた際に、太腿の間から反対側のタブ３０（係合部３２Ｂ）が視認されやすい。よって、着用者は、次に反対側のタブ３０を開いて破る動作を行うことを意識しやすく、次の動作に移行しやすくなる。 By doing so, when the wearer wraps the waist member 20 around the thigh, the tab 30 (engagement portion 32B) on the opposite side is easily visible from between the thighs. Therefore, the wearer is more likely to be conscious of the action of opening and breaking the tab 30 on the opposite side next, so that the wearer can easily move to the next action.
　また、係合部３２の中心線ＣＬ１が水平となるようにナプキン１を保持したときに（図２３）、その係合部３２（３２Ａ）の縦方向における胴回り側の端３２Ａａを通る鉛直線ＬＶに対して、下側のタブ３０の係合部３２（３２Ｂ）の少なくとも一部が、胴回り側に位置しているとよい。 Further, when the napkin 1 is held so that the center line CL1 of the engaging portion 32 is horizontal (FIG. 23), a vertical line LV passing through the end 32Aa of the engaging portion 32 (32A) on the waist side in the vertical direction On the other hand, at least a portion of the engaging portion 32 (32B) of the lower tab 30 is preferably located on the waist circumference side.
　そうすることで、着用者が胴回り部材２０を太腿に巻き付けた際に、反対側のタブ３０（係合部３２Ｂ）が着用者の近くに位置する。そのため、着用者は、前かがみの姿勢にならなくとも、目線を下に落とすだけで、反対側のタブ３０（係合部３２Ｂ）を見つけることができ、次の動作に移行しやすくなる。 By doing so, when the wearer wraps the waist member 20 around the thigh, the tab 30 (engaging portion 32B) on the opposite side is positioned near the wearer. Therefore, the wearer can find the tab 30 (engagement portion 32B) on the opposite side by simply looking down without bending forward, and can easily move to the next operation.
　また、前述したナプキン１の装着方法では、胴回り部材２０が太腿に巻き付けられた後、図１６Ｃに示すようにナプキン１を引き上げた状態で、反対側のタブ３０を開いて前胴回り部２０ｆを破る方法を説明したが、これに限らない。例えば、図１６Ｂに示すように、反対側の太腿の下からタブ３０を掴み、太腿の下でタブ３０を開いて前胴回り部２０ｆを破るようにしてもよい。その場合、その前胴回り部２０ｆの破いた部分をそのまま下から太腿に巻き付けることができる。その場合、上記のように、反対側のタブ３０（係合部３２Ｂ）が着用者の近くに位置することで、着用者は太腿の下からタブ３０を掴みやすくなる。 In addition, in the method of wearing the napkin 1 described above, after the waist member 20 is wrapped around the thigh, the napkin 1 is pulled up as shown in FIG. Although the method of breaking has been described, it is not limited to this. For example, as shown in FIG. 16B, tab 30 may be grasped from under the opposite thigh and tab 30 may be opened under the thigh to break front waistline 20f. In that case, the torn portion of the front waist portion 20f can be wrapped around the thigh from below as it is. In this case, as described above, the tab 30 (engagement portion 32B) on the opposite side is positioned near the wearer, making it easier for the wearer to grasp the tab 30 from below the thigh.
　また、本実施形態のナプキン１は、成人用のパンツ型吸収性物品であるが（初潮を迎えた小中学生も着用対象者に含む）、吸収性コア１１の体積が比較的に小さい。厳密には、吸収性コア１１が配されているナプキン１の部位の体積が比較的に小さく、１００ｃｍ３以上２５０ｃｍ３以下とする。 Further, the napkin 1 of the present embodiment is a pants-type absorbent article for adults (including elementary and junior high school students who have reached menarche), but the volume of the absorbent core 11 is relatively small. Strictly speaking, the volume of the portion of the napkin 1 where the absorbent core 11 is arranged is relatively small, and is set to 100 cm 3 or more and 250 cm 3 or less.
　吸収性コア１１が配されているナプキン１の部位の体積とは、「吸収性コア１１の長手方向の長さ」と、「吸収性コア１１の幅」と、「吸収性コア１１が配されているナプキン１の部位の厚み（図１２のトップシート１１～非肌側シート２１までの厚み）」を、乗じることで得られる。ただし、吸収性コア１１に重ねられるシートの厚みは吸収性コア１１の厚みに比べて小さい。そのため、吸収性コア１１が配されているナプキン１の部位の体積は、吸収性コア１１の体積に近いので、本明細書では、吸収性コア１１が配されているナプキン１の部位の体積を、単に「吸収性コア１１の体積」ともいう。 The volume of the portion of the napkin 1 where the absorbent core 11 is arranged includes the "longitudinal length of the absorbent core 11", the "width of the absorbent core 11", and the "width of the absorbent core 11". It is obtained by multiplying the thickness of the part of the napkin 1 that is attached (the thickness from the top sheet 11 to the non-skin side sheet 21 in FIG. 12). However, the thickness of the sheet overlaid on the absorbent core 11 is smaller than the thickness of the absorbent core 11 . Therefore, the volume of the portion of the napkin 1 where the absorbent core 11 is arranged is close to the volume of the absorbent core 11, so in this specification, the volume of the portion of the napkin 1 where the absorbent core 11 is arranged is , simply referred to as "the volume of the absorbent core 11".
　吸収性コア１１の体積を２５０ｃｍ３以下と小さくすることで、吸収性コア１１の質量や寸法（長さ、幅、厚み等）を小さくできる。よって、着用者がナプキン１をテープ型にして装着するために胴回り部材２０を太腿に巻き付けた際に、ナプキン１の質量の大部分を占める吸収性コア１１が垂れ下がり難くなり、ナプキン１の便器への接触を抑制できる。よって、ナプキン１の衛生状態を良好に維持でき、装着性も向上する。また、自分で装着する着用者を対象とした成人用のパンツ型吸収性物品（例えば本実施形態のナプキン１や軽失禁用のおむつ等）の場合、介護用のパンツ型吸収性物品に比べて、排泄量が少ない。そのため、吸収性コア１１の体積を１００ｃｍ３以上２５０ｃｍ３以下としても、排泄液の漏れを抑制できる。 By reducing the volume of the absorbent core 11 to 250 cm 3 or less, the mass and dimensions (length, width, thickness, etc.) of the absorbent core 11 can be reduced. Therefore, when the wearer wraps the waist member 20 around the thighs in order to wear the napkin 1 in a tape shape, the absorbent core 11, which occupies most of the mass of the napkin 1, does not easily hang down, and the toilet bowl of the napkin 1. can suppress contact with Therefore, the sanitary condition of the napkin 1 can be maintained well, and the wearability is also improved. In addition, in the case of an adult pants-type absorbent article for a wearer who wears it by himself (for example, the napkin 1 of the present embodiment, a diaper for light incontinence, etc.), compared to a nursing pants-type absorbent article , low excretion. Therefore, even if the volume of the absorbent core 11 is 100 cm 3 or more and 250 cm 3 or less, the leakage of excrement can be suppressed.
　具体的には、吸収性コア１１の幅が５０ｍｍ以上１００ｍｍ未満であることが好ましい。吸収性コア１１の幅を１００ｍｍ未満とすることで、吸収性コア１１の体積を上記のように小さくできる。また、胴回り部材２０が太腿に巻き付けられた際の、吸収性コア１１の最下端の位置１１Ｌ（図２４参照）を上方に位置させることができる。よって、ナプキン１の便器への接触を抑制できる。一方、吸収性コア１１の幅を５０ｍｍ以上とすることで、着用者に安心感を付与でき、排泄液の横漏れも抑制できる。 Specifically, the width of the absorbent core 11 is preferably 50 mm or more and less than 100 mm. By setting the width of the absorbent core 11 to less than 100 mm, the volume of the absorbent core 11 can be reduced as described above. In addition, the lowermost position 11L (see FIG. 24) of the absorbent core 11 can be positioned upward when the waist member 20 is wrapped around the thigh. Therefore, the contact of the napkin 1 with the toilet bowl can be suppressed. On the other hand, by setting the width of the absorbent core 11 to 50 mm or more, it is possible to provide the wearer with a sense of security and to suppress lateral leakage of excrement.
　また、展開かつ伸張状態であるパンツ型吸収性物品において、吸収性コア１１が配されている部位のナプキン１の厚み、つまり、吸収性コア１１と吸収性コア１１に重ねて配されるシートの合計厚みが５．５ｍｍ未満であることが好ましい。ただし、吸収性コア１１の体積と同様に、吸収性コア１１に重ねられるシートの厚みは吸収性コア１１の厚みに比べて小さいので、本明細書では、吸収性コア１１が配されている部位のナプキン１の厚みを、単に「吸収性コア１１の厚み」ともいう。 In addition, in the pants-type absorbent article in the unfolded and stretched state, the thickness of the napkin 1 at the portion where the absorbent core 11 is arranged, that is, the thickness of the absorbent core 11 and the sheet arranged to overlap the absorbent core 11 A total thickness of less than 5.5 mm is preferred. However, as with the volume of the absorbent core 11, the thickness of the sheet superimposed on the absorbent core 11 is smaller than the thickness of the absorbent core 11. The thickness of the napkin 1 is also simply referred to as "the thickness of the absorbent core 11".
　吸収性コア１１の厚みを５．５ｍｍ未満とすることで、吸収性コア１１の体積を上記のように小さくでき、また、ナプキン１の前後方向の膨らみを抑えることができるため、ナプキン１の便器への接触を抑制できる。 By setting the thickness of the absorbent core 11 to be less than 5.5 mm, the volume of the absorbent core 11 can be reduced as described above, and the bulging of the napkin 1 in the front-rear direction can be suppressed. can suppress contact with
　また、吸収性コア１１の質量が１０ｇ以上４０ｇ以下であることが好ましい。吸収性コア１１の質量を４０ｇ以下とすることで、胴回り部材２０が太腿に巻き付けられた際の吸収性コア１１の垂れ下がりを抑制でき、ナプキン１の便器への接触を抑制できる。一方、吸収性コア１１の質量を１０ｇ以上とすることで、排泄液の漏れを抑制できる。 Further, it is preferable that the mass of the absorbent core 11 is 10 g or more and 40 g or less. By setting the mass of the absorbent core 11 to 40 g or less, it is possible to suppress the absorbent core 11 from sagging when the waist member 20 is wrapped around the thigh, and to suppress the contact of the napkin 1 with the toilet bowl. On the other hand, by setting the mass of the absorbent core 11 to 10 g or more, leakage of excrement can be suppressed.
　吸収性コア１１の体積、幅、厚み、質量の測定方法を以下に説明する。　
（１）図１１に示すように皺がない程度にナプキン１を展開かつ伸張状態にして、吸収性コア１１を平面的に広げた状態での長手方向（ナプキン１の縦方向）の最大長さを測定する。　
（２）次に、吸収性コア１１を長手方向に３分割した領域Ｒ１～Ｒ３に区画する（図２１参照）。そして、各領域Ｒ１～Ｒ３の長手方向の中心位置における、吸収性コア１１の幅Ｗ１～Ｗ３を測定する。その３つの幅Ｗ１～Ｗ３の平均値を吸収性コア１１の幅Ｗとする。
その幅Ｗが５０ｍｍ以上１００ｍｍ未満であることが好ましい。　
（３）次に、吸収性コア１１を長手方向に３分割した領域Ｒ１～Ｒ３の各中心（長手方向及び幅方向の中心）における、吸収性コア１１の厚みｔ１～ｔ３を測定する。その３つの厚みｔ１～ｔ３の平均値を吸収性コア１１の厚みｔ（吸収性コア１１が配されている部位のナプキン１の厚み）とする。その厚みｔが５．５ｍｍ未満であることが好ましい。　（４）そして、吸収性コア１１の長さと幅Ｗと厚みｔを乗じた値を、吸収性コア１１の体積（吸収性コア１１が配されているナプキン１の部位の体積）とする。その体積が１００ｃｍ３以上２５０ｃｍ３以下であることが好ましい。
（５）質量の測定は、上記寸法を測定した後に行う。まず、トルエンを用いてナプキン１を構成する資材を分離して、吸収性コア１１（コアラップシートも含む）を取り出す。分離した吸収性コア１１を、２４時間自然乾燥させた後に、吸収性コア１１（パルプ繊維やＳＡＰやコアラップシート等）の質量を測定する。その質量が１０ｇ以上４０ｇ以下であることが好ましい。 Methods for measuring the volume, width, thickness and mass of the absorbent core 11 will be described below.
(1) As shown in FIG. 11, the napkin 1 is unfolded and stretched to the extent that there are no wrinkles, and the maximum length in the longitudinal direction (longitudinal direction of the napkin 1) when the absorbent core 11 is spread out in a plane. to measure.
(2) Next, the absorbent core 11 is longitudinally divided into three regions R1 to R3 (see FIG. 21). Then, the widths W1 to W3 of the absorbent core 11 are measured at the longitudinal central positions of the regions R1 to R3. The width W of the absorbent core 11 is defined as the average value of the three widths W1 to W3.
The width W is preferably 50 mm or more and less than 100 mm.
(3) Next, the thicknesses t1 to t3 of the absorbent core 11 are measured at the respective centers (centers in the longitudinal and width directions) of regions R1 to R3 obtained by dividing the absorbent core 11 into three in the longitudinal direction. The average value of the three thicknesses t1 to t3 is defined as the thickness t of the absorbent core 11 (the thickness of the napkin 1 at the portion where the absorbent core 11 is arranged). Its thickness t is preferably less than 5.5 mm. (4) Then, a value obtained by multiplying the length of the absorbent core 11 by the width W and the thickness t is defined as the volume of the absorbent core 11 (the volume of the portion of the napkin 1 where the absorbent core 11 is arranged). Its volume is preferably 100 cm 3 or more and 250 cm 3 or less.
(5) Measurement of mass is performed after measuring the above dimensions. First, the material constituting the napkin 1 is separated using toluene, and the absorbent core 11 (including the core wrap sheet) is taken out. After air-drying the separated absorbent core 11 for 24 hours, the mass of the absorbent core 11 (pulp fiber, SAP, core wrap sheet, etc.) is measured. It is preferable that the mass is 10 g or more and 40 g or less.
　また、吸収性コア１１の垂れ下がりを抑制するために、特に、ナプキン１の２つ折り部Ｆにおける、吸収性コア１１の幅方向の側縁の厚みが薄いことが好ましい。具体的には、吸収性コア１１の２つ折り部Ｆにおける、幅方向の側縁の厚みは、上記の測定方法にて測定した吸収性コア１１の厚み（すなわち幅方向中央部の厚み）よりも薄く、４ｍｍ以下であるとよい。なお、吸収性コア１１の側縁の厚みは、上記測定方法と同じ方法により、測定箇所を変えて測定する。また、１つのナプキン１につき２箇所（左右の側縁）の厚みを測定し、平均値を吸収性コア１１の側縁の厚みとする。 In addition, in order to suppress sagging of the absorbent core 11, it is preferable that the thickness of the side edge in the width direction of the absorbent core 11 is particularly thin at the two-folded portion F of the napkin 1. Specifically, the thickness of the side edges in the width direction of the two-fold portion F of the absorbent core 11 is greater than the thickness of the absorbent core 11 measured by the above measuring method (that is, the thickness of the central portion in the width direction). It should be thin, 4 mm or less. In addition, the thickness of the side edge of the absorbent core 11 is measured by the same method as the above-described measuring method while changing the measuring point. The thickness of each napkin 1 is measured at two points (left and right side edges), and the average value is taken as the thickness of the side edge of the absorbent core 11 .
　なお、吸収性コア１１の厚さは、例えば、ミツトヨ（株）製のダイアルシックネスゲージＩＤ－Ｃ１０１２Ｃ又はそれと同等のものを使用し、対象部位を例えば３．０ｇｆ／ｃｍ２で加圧して測定した値とする。 The thickness of the absorbent core 11 is measured by using, for example, a dial thickness gauge ID-C1012C manufactured by Mitutoyo Co., Ltd. or its equivalent, and applying pressure to the target site at, for example, 3.0 gf/cm 2 . value.
　また、吸収性コア１１の体積、幅、厚み、質量の測定は、複数（例えば５個）のナプキン１について測定し、その平均値が上記範囲に含まれていることを確認することが好ましい。測定対象のナプキン１は、同じパッケージに入っているナプキンであることが好ましいが、同じ段ボールに入っているナプキン又は製造日が同じであるナプキンであってもよい。 In addition, it is preferable to measure the volume, width, thickness, and mass of the absorbent core 11 for a plurality of (eg, five) napkins 1 and confirm that the average value is within the above range. The napkins 1 to be measured are preferably napkins contained in the same package, but may be napkins contained in the same cardboard or napkins having the same production date.
　また、図１１に示すように、展開かつ伸張状態であるナプキン１において、縦方向（幅方向に直交する方向であり、吸収性本体１０の長手方向に沿う方向）におけるナプキン１の一方側の端から中心ＣＬまでの長さＬ６が、２００ｍｍ以上３５０ｍｍ以下であることが好ましい。長さＬ６を３５０ｍｍ以下とすることで、胴回り部材２０から股下側に延びるナプキン１の部位の長さも適度に小さくなるため、胴回り部材２０が太腿に巻き付けられた際にナプキン１が垂れ下がり難く、ナプキン１の便器への接触を抑制できる。一方、長さＬ６を２００ｍｍ以上とすることで、成人にフィットするサイズとなる。 Further, as shown in FIG. 11, in the napkin 1 in the unfolded and stretched state, one end of the napkin 1 in the longitudinal direction (the direction orthogonal to the width direction and along the longitudinal direction of the absorbent body 10) to the center CL is preferably 200 mm or more and 350 mm or less. By setting the length L6 to 350 mm or less, the length of the portion of the napkin 1 extending from the waist member 20 to the crotch side is appropriately reduced, so that the napkin 1 does not easily hang down when the waist member 20 is wrapped around the thigh. Contact of the napkin 1 with the toilet bowl can be suppressed. On the other hand, setting the length L6 to 200 mm or more provides a size that fits an adult.
　また、図１１に示すように、吸収性コア１１の幅は、吸収性本体１０の幅よりも狭く、吸収性本体１０は、幅方向の側部において、吸収性コア１１が存在しない領域を有することが好ましい。 Further, as shown in FIG. 11, the width of the absorbent core 11 is narrower than the width of the absorbent main body 10, and the absorbent main body 10 has a region in which the absorbent core 11 does not exist on the lateral sides in the width direction. is preferred.
　そうすることで、吸収性本体１０の幅方向の側部では剛性が低くなる。よって、太腿に胴回り部材２０が巻き付けられ後に、着用者が胴回り部材２０を回転させて吸収性本体１０を引き上げる際に、吸収性本体１０の側部が着用者の太腿の周方向に沿いやすく、胴回り部材２０を回転しやすくなる。よって、ナプキン１の装着性が向上する。 By doing so, the lateral sides of the absorbent body 10 in the width direction are less rigid. Therefore, after the waist member 20 is wrapped around the thighs, when the wearer rotates the waist member 20 and pulls up the absorbent main body 10, the side portions of the absorbent main body 10 extend along the circumferential direction of the wearer's thighs. This makes it easier to rotate the waist member 20. Therefore, the wearability of the napkin 1 is improved.
　また、本実施形態のナプキン１のように、胴回り部材２０の幅方向の両側に一対のタブ３０が設けられている好ましい。そうすることで、図１５Ｃや図１６Ｄに示すように、胴回り部材２０を両太腿に巻き付けてナプキン１を装着できる。また、ナプキン１を取り外す際には、一対のタブ３０を前胴回り部２０ｆから取り外して、太腿の間からナプキン１を引き抜くことができる。よって、パンツ型のままでナプキン１を着脱する場合のように、ナプキン１の脚回り開口１ｂにつま先を通して着脱する必要がない。ゆえに、着用者がズボンや靴やストッキング等を脱がなくてもナプキン１を着脱でき、外出先でもナプキン１を容易に交換できる。 Also, like the napkin 1 of this embodiment, it is preferable that a pair of tabs 30 be provided on both sides of the waist member 20 in the width direction. By doing so, as shown in FIG. 15C and FIG. 16D, the napkin 1 can be worn by wrapping the waist member 20 around both thighs. When removing the napkin 1, the pair of tabs 30 are removed from the front waist portion 20f, and the napkin 1 can be pulled out from between the thighs. Therefore, unlike the case of putting on and taking off the napkin 1 in the form of pants, it is not necessary to pass the toe through the opening 1b around the leg of the napkin 1 to put on and take off. Therefore, the wearer can put on and take off the napkin 1 without taking off pants, shoes, stockings, etc., and can easily replace the napkin 1 on the go.
　また、本実施形態のナプキン１のように、胴回り部材２０の幅方向の一方側に、係合部３２を１つ有するタブ３０（係合部材）が１つ設けられ、胴回り部材２０の幅方向の他方側に、係合部３２を１つ有するタブ３０（他の係合部材）が１つ設けられていることが好ましい。つまり、ナプキン１の幅方向の両側にタブ３０が１つずつ設けられていることが好ましい。 In addition, like the napkin 1 of the present embodiment, one tab 30 (engaging member) having one engaging portion 32 is provided on one side in the width direction of the waist member 20, and the width direction of the waist member 20 Preferably, one tab 30 (another engaging member) having one engaging portion 32 is provided on the other side of the . That is, it is preferable that one tab 30 is provided on each side of the napkin 1 in the width direction.
　そうすることで、着用者は、タブ３０（係合部３２）を幅方向の両側で１回ずつ係合するだけでよく、容易に装着できる。ナプキン１の外観も向上する。また、本実施形態のナプキン１のように、自分で装着する着用者を対象としたパンツ型吸収性物品の場合、排泄量が少なく、排泄後の吸収性コア１１も軽い。そのため、本実施形態のナプキン１では、介護用のパンツ型吸収性物品のように例えば縦方向に係合部が２つ並んだタブを設けたり、係合部を１つ有するタブを縦方向に２つ並べたりして、タブを前胴回り部２０ｆに強固に固定しなくても、ナプキン１のずれ落ちの恐れが少ない。 By doing so, the wearer only has to engage the tabs 30 (engaging portions 32) once on both sides in the width direction, and can easily wear the garment. The appearance of the napkin 1 is also improved. Further, in the case of a pants-type absorbent article intended for a wearer who puts it on by himself like the napkin 1 of this embodiment, the amount of excretion is small, and the absorbent core 11 after excretion is also light. Therefore, in the napkin 1 of the present embodiment, for example, a tab having two engaging portions arranged in the vertical direction is provided like a pants-type absorbent article for nursing care, or a tab having one engaging portion is provided in the vertical direction. Even if two tabs are arranged side by side and the tabs are not firmly fixed to the front waist part 20f, the napkin 1 is less likely to slip off.
　但し、係合部３２及びタブ３０の数は幅方向の両側で１つずつに限定されるものではない。また、胴回り部材２０の幅方向の一方側にのみタブ３０が設けられているナプキン１であってもよい。つまり、本実施形態のナプキン１は、少なくとも幅方向の片側をテープ型として使用可能なパンツ型吸収性物品であればよい。 However, the number of engaging portions 32 and tabs 30 is not limited to one on both sides in the width direction. Alternatively, the napkin 1 may have the tab 30 only on one side of the waist member 20 in the width direction. In other words, the napkin 1 of the present embodiment may be a pants-type absorbent article that can be used as a tape type at least on one side in the width direction.
　また、前胴回り部２０ｆ及び後胴回り部２０ｂは、幅方向に伸縮する肌側シート２２，２３を有し、かつ、縦方向の胴回り側の端部において、幅方向に伸縮する胴回り弾性部材２４（例えば糸ゴム）を複数有する。図１１や図２１に示すように、前胴回り部２０ｆ及び後胴回り部２０ｂは、少なくとも幅方向の位置が吸収性本体１０と重複する領域において、幅方向に伸縮する伸縮領域２０ＥＡを連続して有することが好ましい。 The front waist portion 20f and the rear waist portion 20b have skin- side sheets 22 and 23 that stretch in the width direction, and waist elastic members 24 that stretch in the width direction ( For example, it has a plurality of thread rubbers). As shown in FIGS. 11 and 21, the front waistline portion 20f and the rear waistline portion 20b have a continuous stretchable region 20EA that stretches in the width direction at least in a region where the position in the width direction overlaps with the absorbent main body 10. is preferred.
　そうすることで、ナプキン１が着用者の胴回りにフィットする。特に、ナプキン１がテープ型として使用される場合（図１３Ｂ）、前胴回り部２０ｆの腹側当接部２０ｆＡが後胴回り部２０ｂから分離されるが、一対のタブ３０の間で腹側当接部２０ｆＡが幅方向の両外側に引っ張られ、着用者の胴回りにフィットする。 By doing so, napkin 1 fits around the wearer's waist. In particular, when the napkin 1 is used as a tape type (FIG. 13B), the ventral contact portion 20fA of the front waistline portion 20f is separated from the back waistline portion 20b, but the ventral contact portion 20fA of the front waistline portion 20f is separated from the back waistline portion 20b. The portion 20fA is pulled outward on both sides in the width direction to fit the waist of the wearer.
　また、着用者が胴回り部材２０を太腿に巻き付ける際に、腹側当接部２０ｆＡを太腿の前側に引っ張ってきやすくなり、太腿の上でタブ３０を腹側当接部２０ｆＡに係合しやすくなる。また、肌側シート２２，２３及び胴回り弾性部材２４によって、前胴回り部２０ｆ及び後胴回り部２０ｂが幅方向に収縮し（太腿の周りにフィットし）、ナプキン１が垂れ下がり難くなる。よって、ナプキン１の便器への接触を抑制できる。 Further, when the wearer wraps the waist member 20 around the thigh, the abdominal contact portion 20fA is easily pulled toward the front of the thigh, and the tab 30 is engaged with the abdominal contact portion 20fA on the thigh. easier to do. The skin- side sheets 22 and 23 and the waist elastic member 24 cause the front waist portion 20f and the rear waist portion 20b to contract in the width direction (to fit around the thighs), so that the napkin 1 does not easily hang down. Therefore, the contact of the napkin 1 with the toilet bowl can be suppressed.
　ただし、伸縮領域２０ＥＡのうち、吸収性コア１１と厚さ方向に重なる領域では、伸縮力を軽減し、吸収性コア１１の平坦性を確保するようにしてもよい。例えば、吸収性コア１１と厚さ方向に重なる領域では、それ以外の領域に比べて、非肌側シート２１と肌側シート２２，２３の接合部（溶着部）の面積率を高めて、肌側シート２２，２３の弾性特性を抑制するとよい。そうすることで、吸収性コア１１の吸収面積を確保でき、また、吸収性コア１１と着用者の間に隙間が生じてしまうことを防止できる。 However, in the elastic area 20EA, in the area overlapping the absorbent core 11 in the thickness direction, the elastic force may be reduced to ensure the flatness of the absorbent core 11. For example, in the region overlapping the absorbent core 11 in the thickness direction, the area ratio of the joints (welded portions) between the non-skin-side sheet 21 and the skin- side sheets 22 and 23 is increased compared to the other regions, thereby It is preferable to suppress the elastic properties of the side sheets 22 and 23 . By doing so, it is possible to secure the absorbent area of the absorbent core 11 and prevent the occurrence of a gap between the absorbent core 11 and the wearer.
　また、前胴回り部２０ｆは、伸縮領域２０ＥＡよりも幅方向の外側（タブ３０が設けられている側）に、伸縮領域２０ＥＡよりも伸縮性の低い低伸縮領域２０ＮＡを有しているとよい。低伸縮領域２０ＮＡが設けられていることで、着用者が前胴回り部２０ｆを幅方向に引っ張って破る際に、その力が破断部に効率よく伝わり、小さい力で破ることができる。ナプキン１が切り取り線２６を有する場合、幅方向における低伸縮領域２０ＮＡの両側端の間に、切り取り線２６が配置されていることが好ましい。そうすることで、切り取り線２６の両外側が伸張し難いため、前胴回り部２０ｆを破りやすくなる。また、前胴回り部２０ｆの切れ端が低伸縮領域２０ＮＡにより丸まり難いため、前胴回り部２０ｆにタブ３０を係合しやすくなり、前胴回り部２０ｆの切れ端を着用者が異物として感じ難くなる。そのため、前胴回り部２０ｆは、少なくとも幅方向の位置が吸収性本体１０と重複する領域において、伸縮領域２０ＥＡを連続して有することが好ましい。 In addition, the front waist portion 20f preferably has a low stretchable region 20NA having a lower stretchability than the stretchable region 20EA outside the stretchable region 20EA in the width direction (on the side where the tab 30 is provided). With the provision of the low-stretch region 20NA, when the wearer pulls the front waistline portion 20f in the width direction to break it, the force is efficiently transmitted to the breaking portion, and the front waistline portion 20f can be broken with a small force. When the napkin 1 has a perforation line 26, the perforation line 26 is preferably arranged between both side ends of the low stretchable region 20NA in the width direction. By doing so, it is difficult to stretch both outer sides of the perforated line 26, so that the front waistline portion 20f is easily broken. In addition, since the cut ends of the front waistline portion 20f are less likely to curl up due to the low-stretch region 20NA, the tabs 30 can be easily engaged with the front waistline portion 20f, and the wearer hardly feels the cut ends of the front waistline portion 20f as a foreign object. Therefore, it is preferable that the front waistline portion 20f has the stretchable region 20EA continuously in at least the region where the position in the width direction overlaps with the absorbent main body 10. As shown in FIG.
　一方、ナプキン１の後方部は、前方部に比べて便器の近くに位置しやすく、太腿の下を通されて巻き付けられるので便器に接触しやすい。そのため、後胴回り部２０ｂは、幅方向における一対のサイド接合部４０間の領域において、伸縮領域２０ＥＡを連続して有することが好ましい。そうすることで、後胴回り部２０ｂでは、幅方向のより広い範囲に伸縮性が付与され、着用者の太腿に胴回り部材２０が巻き付けられた際に、ナプキン１の後方部の垂れ下がりを抑制できる。 On the other hand, the rear part of the napkin 1 is more likely to be positioned closer to the toilet bowl than the front part, and can be passed under the thighs and wrapped around the toilet bowl, making it easier to contact the toilet bowl. Therefore, it is preferable that the rear waist portion 20b has a continuous elastic region 20EA in the region between the pair of side joints 40 in the width direction. By doing so, the rear waist portion 20b is given stretchability in a wider range in the width direction, and when the waist member 20 is wrapped around the thighs of the wearer, the back portion of the napkin 1 can be suppressed from sagging. .
　また、後胴回り部２０ｂは、その非肌側面を形成する非肌側シート２１を有するが、図１１や図１２に示すように、縦方向における非肌側シート２１の胴回り側の端部は、肌側に折り返されている。そして、後側の吸収性本体１０の縦方向の端部を肌側から覆っている。 In addition, the rear waist portion 20b has a non-skin side sheet 21 forming the non-skin side, but as shown in FIGS. It is folded back on the skin side. And it covers the longitudinal end of the back absorbent main body 10 from the skin side.
　そうすることで、後胴回り部２０ｂの上端部（胴回り側の端部）では、多くの資材が厚さ方向に重なり、剛性が高くなる。そのため、太腿に胴回り部材２０が巻き付けられる際に、より便器に接触しやすいナプキン１の後方部（後胴回り部２０ｂ）の剛性を高めることができ、ナプキン１の後方部の垂れ下がりを抑制できる。 By doing so, at the upper end portion (end portion on the waistline side) of the rear waist portion 20b, many materials overlap in the thickness direction, increasing the rigidity. Therefore, when the waist member 20 is wrapped around the thigh, the rigidity of the rear part (rear waist part 20b) of the napkin 1, which is more likely to come into contact with the toilet bowl, can be increased, and sagging of the rear part of the napkin 1 can be suppressed.
　また、本実施形態のナプキン１では、図１１に示すように、吸収性本体１０が、幅方向の側部において、吸収性本体１０の長手方向に沿って伸縮する防漏壁弾性部材１４１（側部弾性部材）を有している。この場合、前胴回り部２０ｆ及び後胴回り部２０ｂの少なくとも一方が有する伸縮領域２０ＥＡにおける幅方向の応力（伸縮応力）は、防漏壁弾性部材１４１が配置されている領域における長手方向の応力（伸縮応力）よりも大きいことが好ましい。 Further, in the napkin 1 of the present embodiment, as shown in FIG. 11, the absorbent main body 10 has leak-proof wall elastic members 141 (sides) extending and contracting along the longitudinal direction of the absorbent main body 10 at the lateral sides thereof in the width direction. part elastic member). In this case, the stress in the width direction (stretching stress) in the stretchable region 20EA of at least one of the front waistline portion 20f and the rear waistline portion 20b is the stress in the longitudinal direction (stretching stress) in the region where the leakproof wall elastic member 141 is arranged. stress).
　前胴回り部２０ｆ及び後胴回り部２０ｂの伸縮応力を高めることで、着用者の胴回りへのナプキン１のフィット性を高めることができる。また、太腿に胴回り部材２０が巻き付けられる際の、ナプキン１の垂れ下がりを抑制できる。一方、吸収性本体１０の側部の伸縮応力を抑えることで、太腿に巻き付けた胴回り部材２０を太腿の周方向に沿って回転する際に、吸収性本体１０がその長手方向に伸び難いため、胴回り部材２０を回転しやすくなる。また、ナプキン１の場合、介護用のおむつに比べて、排泄量が少ないため、防漏壁弾性部材１４１の伸縮応力が弱くとも、排泄液を堰き止めることができ、横漏れを抑制できる。 By increasing the elastic stress of the front waist portion 20f and the rear waist portion 20b, the fit of the napkin 1 to the wearer's waist can be improved. In addition, sagging of the napkin 1 when the waist member 20 is wrapped around the thigh can be suppressed. On the other hand, by suppressing the stretching stress of the side portion of the absorbent main body 10, when the waist member 20 wrapped around the thigh is rotated along the circumferential direction of the thigh, the absorbent main body 10 is less likely to stretch in its longitudinal direction. Therefore, the waist member 20 can be easily rotated. Further, in the case of the napkin 1, since the amount of excretion is smaller than that of nursing care diapers, even if the elastic stress of the leak-proof wall elastic member 141 is weak, the excreted liquid can be dammed up and side leakage can be suppressed.
　なお、前胴回り部２０ｆ又は後胴回り部２０ｂの幅方向の伸縮応力と、吸収性本体１０の側部の長手方向の伸縮応力との比較は、引っ張り試験機（例えば（株）島津製作所製のオートグラフ型引張試験機ＡＧ－１ＫＮ１等）を用いて確認できる。まず、胴回り部材２０ｆから、前胴回り部２０ｆの伸縮領域２０ＥＡの全て（低伸縮領域２０ＮＡを有する場合はそれを除く領域）、又は、後胴回り部２０ｂの伸縮領域２０ＥＡの全てを切り出す。
また、吸収性本体１０から、防漏壁弾性部材１４１の伸縮部の全てを含む領域を切り出す。切り出した伸縮領域２０ＥＡの幅方向（伸縮方向）の長さ×幅（伸縮方向に直交する方向の長さ）と、切り出した防漏壁弾性部材１４１の伸縮部の長手方向（伸縮方向）の長さ×幅が、同じとなるように（例えば２００ｍｍ×２５ｍｍとなるように）、サンプルを作製する。そして、各サンプルの伸縮方向の両端部をチャックで挟み、１００ｍｍ／ｍｉｎのスピードでチャック間隔を離し、最大伸長状態になるまでサンプルを伸長させた後に、反転させて８０％まで収縮したときの引張荷重（Ｎ／２５ｍｍ）を取得する。その引張荷重（Ｎ／２５ｍｍ）を各サンプルの応力（伸縮応力）として比較するとよい。なお、胴回り部２０ｆ，２０ｂの場所に応じて応力が異なる場合、少なくとも胴回り部２０ｆ，２０ｂの最大応力が、吸収性本体１０の側部の応力よりも大きければよく、より好ましくは、胴回り部２０ｆ，２０ｂの最小応力が、吸収性本体１０の側部の応力よりも大きいとよい。 The comparison between the stretching stress in the width direction of the front waist portion 20f or the rear waist portion 20b and the stretching stress in the longitudinal direction of the side portions of the absorbent body 10 can be made using a tensile tester (for example, an auto tester manufactured by Shimadzu Corporation). It can be confirmed using a graph type tensile tester AG-1KN1, etc.). First, from the waist member 20f, the entire stretchable region 20EA of the front waistline portion 20f (excluding the low stretchable region 20NA, if any) or the entire stretchable region 20EA of the rear waistline portion 20b is cut out.
Also, a region including all the stretchable portions of the leak-proof wall elastic member 141 is cut out from the absorbent main body 10 . The length in the width direction (stretching direction) of the cut-out elastic region 20EA x the width (the length in the direction perpendicular to the stretching direction), and the length in the longitudinal direction (stretching direction) of the elastic part of the cut-out leak-proof wall elastic member 141 Samples are prepared so that the width and height are the same (for example, 200 mm x 25 mm). Then, both ends of each sample in the stretching direction are pinched with chucks, the chuck interval is separated at a speed of 100 mm / min, the sample is stretched until it reaches the maximum stretched state, and then it is reversed and contracted to 80%. Obtain the load (N/25 mm). The tensile load (N/25 mm) should be compared as the stress (stretching stress) of each sample. When the stress varies depending on the location of the waistline portions 20f and 20b, at least the maximum stress of the waistline portions 20f and 20b should be greater than the stress of the side portions of the absorbent main body 10, and more preferably the waistline portion 20f. , 20b should be greater than the stress on the sides of the absorbent body 10 .
　また、図１１に示すように、吸収性本体１０は、その長手方向に沿って伸縮する吸収体弾性部材１５を複数有する。吸収体弾性部材１５は、例えば糸ゴムによって構成され、吸収性コア１１の非肌側に位置する液不透過性シート１３ａよりも非肌側（図１２では、液不透過性シート１３ａと疎水性シート１３ｂとの間）に、長手方向に伸長した状態で配置されている。本実施形態のナプキン１では、幅方向に所定の間隔を空けて５本の吸収体弾性部材１５が設けられている。 Also, as shown in FIG. 11, the absorbent body 10 has a plurality of absorbent body elastic members 15 that stretch and contract along its longitudinal direction. The absorbent elastic member 15 is made of thread rubber, for example, and is positioned closer to the non-skin side than the liquid-impermeable sheet 13a located on the non-skin side of the absorbent core 11 (in FIG. 12, the liquid-impermeable sheet 13a and the hydrophobic and the sheet 13b) in a state of being stretched in the longitudinal direction. In the napkin 1 of this embodiment, five absorbent body elastic members 15 are provided at predetermined intervals in the width direction.
　そうすることで、図２２に示すように、吸収性本体１０が収縮して着用者の肌側に持ち上げられ、吸収性本体１０が着用者の股下部（膣口）に密着しやすくなり、排泄液の漏れを抑制できる。また、吸収性本体１０が肌側に持ち上げられることで、胴回り部材２０が太腿に巻き付けられる際に、吸収性本体１０の便器への接触をより抑制できる。なお、吸収体弾性部材１５の伸長倍率は１．４～３．３倍程度とすることが好ましい。伸長倍率は、伸長状態の弾性部材の長さを自然状態の弾性部材の長さで除した値で表される。吸収体弾性部材１５の伸長倍率をある程度強い倍率に設定しておくとよい。 By doing so, as shown in FIG. 22, the absorbent main body 10 is contracted and lifted toward the wearer's skin, and the absorbent main body 10 is easily brought into close contact with the wearer's crotch (vaginal opening) and excreted. Liquid leakage can be suppressed. In addition, since the absorbent main body 10 is lifted toward the skin, contact of the absorbent main body 10 with the toilet bowl can be further suppressed when the waist member 20 is wrapped around the thigh. It is preferable that the expansion ratio of the absorbent body elastic member 15 is about 1.4 to 3.3 times. The extension ratio is represented by a value obtained by dividing the length of the elastic member in the stretched state by the length of the elastic member in the natural state. It is preferable to set the extension ratio of the absorbent body elastic member 15 to a relatively large ratio.
　また、本実施形態のナプキン１は、図１１に示すように、前胴回り部２０ｆ及び後胴回り部２０ｂから、縦方向の股下側に延出する前側延出部２０ｆｅ及び後側延出部２０ｂｅ（延出部材）を有する。前側延出部２０ｆｅ及び後側延出部２０ｂｅによって、着用者の下腹部や臀部を覆うことができ、ナプキン１の外観も向上する。ただし、胴回り部材２０が太腿に巻き付けられる際に、前側延出部２０ｆｅ及び後側延出部２０ｂｅは胴回り部材２０（太腿）から垂れ下がる部分であり、便器に接触する恐れがある。 Moreover, as shown in FIG. 11, the napkin 1 of the present embodiment has a front extending portion 20fe and a rear extending portion 20be ( extension member). The front extending portion 20fe and the rear extending portion 20be can cover the lower abdomen and buttocks of the wearer, and the appearance of the napkin 1 is also improved. However, when the waist member 20 is wrapped around the thighs, the front extension 20fe and the rear extension 20be hang down from the waist member 20 (thighs) and may come into contact with the toilet bowl.
　そこで、前側延出部２０ｆｅ及び後側延出部２０ｂｅに、その脚回り開口１ｂに沿って伸縮する脚回り弾性部材２５（例えば糸ゴム等）を設けることが好ましい。脚回り弾性部材２５によって、前側延出部２０ｆｅ及び後側延出部２０ｂｅが幅方向及び縦方向に収縮する。そのため、胴回り部材２０が太腿に巻き付けられる際の、前側延出部ｆｅ及び後側延出部２０ｂｅの垂れ下がりを抑制し、便器への接触を抑制できる。 Therefore, it is preferable to provide the front extension 20fe and the rear extension 20be with leg elastic members 25 (for example, rubber threads) that extend and contract along the leg openings 1b. The leg elastic member 25 causes the front extension portion 20fe and the rear extension portion 20be to contract in the width direction and the vertical direction. Therefore, when the waist member 20 is wrapped around the thigh, the front extension fe and the rear extension 20be can be prevented from sagging and can be prevented from coming into contact with the toilet bowl.
　また、本実施形態のナプキン１では、図２１に示すように、前胴回り部２０ｆ及び後胴回り部２０ｂ（サイド接合部４０）よりも股下側まで、伸縮性の肌側シート２２，２３が延びている。このように、前側延出部ｆｅ及び後側延出部２０ｂｅの少なくとも一部に、伸縮性の肌側シート２２，２３を配置して、幅方向に伸縮する伸縮領域を設けることが好ましい。そうすることで、胴回り部材２０が太腿に巻き付けられる際の、前側延出部ｆｅ及び後側延出部２０ｂｅの垂れ下がりを抑制し、便器への接触を抑制できる。 In addition, in the napkin 1 of the present embodiment, as shown in FIG. 21, the elastic skin- side sheets 22 and 23 extend from the front waistline portion 20f and the rear waistline portion 20b (side joint portion 40) to the crotch side. there is In this way, it is preferable to arrange the elastic skin- side sheets 22 and 23 on at least a part of the front extending portion fe and the rear extending portion 20be to provide a stretchable region that stretches in the width direction. By doing so, when the waist member 20 is wrapped around the thigh, the front extension fe and the rear extension 20be can be prevented from sagging and can be prevented from coming into contact with the toilet bowl.
　以上のように、本実施形態のナプキン１では、その展開状態において、図２１に示すように、縦方向の一端部から他端部に亘り、何らかの弾性部材（伸縮領域）が配されている。そのため、自然状態のナプキン１では全体が収縮しており、ナプキン１の全体のサイズが小さくなる。よって、太腿に胴回り部材２０が巻き付けられる際に、ナプキン１の垂れ下がりを抑制できる。 As described above, in the napkin 1 of the present embodiment, in its unfolded state, as shown in FIG. 21, some kind of elastic member (stretchable region) is arranged from one end to the other end in the vertical direction. Therefore, the entire napkin 1 in its natural state is contracted, and the overall size of the napkin 1 is reduced. Therefore, when the waist member 20 is wrapped around the thigh, the napkin 1 can be prevented from hanging down.
　また、図２２に示すように、サイド接合部４０に接合されたタブ３０が幅方向の内側に向かって広がった状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、以下であることが好ましい。タブ３０が備える係合部３２は、前側の吸収性本体１０Ｆよりも幅方向の外側の位置に設けられていることと、前側の吸収性本体１０Ｆよりも縦方向の胴回り開口側の位置に設けられていることと、のうちの少なくとも一方であることが好ましい。つまり、タブ３０の係合部３２は、前側の吸収性本体１０と厚さ方向に重ならず、前側の吸収性本体１０の外側に設けられていることが好ましい。本実施形態のナプキン１では、前側の吸収性本体１０Ｆの幅方向の外側に係合部３２が位置している。 Further, as shown in FIG. 22, the napkin in its natural state, in which the tabs 30 joined to the side joints 40 are engaged with the non-skin side surfaces of the front waistline portion 20f in a state where the tabs 30 are spread toward the inside in the width direction. 1, it is preferable that: The engaging portion 32 included in the tab 30 is provided at a position outside the front absorbent main body 10F in the width direction, and at a position closer to the opening side of the waist in the vertical direction than the front absorbent main body 10F. preferably at least one of: That is, it is preferable that the engaging portion 32 of the tab 30 is provided outside the front absorbent main body 10 without overlapping the front absorbent main body 10 in the thickness direction. In the napkin 1 of this embodiment, the engaging portion 32 is positioned outside in the width direction of the front absorbent main body 10F.
　そうすることで、パンツ型のナプキン１をテープ型にするために、着用者がタブ３０（係合部３２）を取り外す際に、吸収性本体１０の一部が破損してしまうことを防止できる。そのため、吸収性本体１０の吸収機能の低下を防止できる。 By doing so, it is possible to prevent part of the absorbent main body 10 from being damaged when the wearer removes the tab 30 (engagement portion 32) in order to make the pants-type napkin 1 tape-type. . Therefore, deterioration of the absorption function of the absorbent main body 10 can be prevented.
　また、前胴回り部２０ｆは幅方向に伸縮性を有するが、剛性の高い吸収性本体１０と厚さ方向に重なる部位では、伸縮性が低下する（伸縮性が意図的に抑えられる場合もある）。伸縮性が低下した前胴回り部２０ｆに係合部３２を係合する場合、係合部３２のフック材が前胴回り部２０ｆの繊維に絡まる度合が小さくなる。そのため、上記のように係合部３２を配することで、吸収性本体１０と厚さ方向に重ならない前胴回り部２０ｆの部位に係合部３２が係合しやすくなり、係合部３２のフック材が前胴回り部２０ｆの繊維に絡まりやすく、タブ３０の係合強度を高めることができる。 In addition, although the front waist portion 20f has elasticity in the width direction, the elasticity is reduced at a portion overlapping the highly rigid absorbent main body 10 in the thickness direction (the elasticity may be intentionally suppressed in some cases). . When the engaging portion 32 is engaged with the front waistline portion 20f whose stretchability has decreased, the degree of entanglement of the hook material of the engaging portion 32 with the fibers of the front waistline portion 20f is reduced. Therefore, by arranging the engaging portion 32 as described above, the engaging portion 32 can be easily engaged with the portion of the front waistline portion 20f that does not overlap with the absorbent body 10 in the thickness direction. The hook material is easily entangled with the fibers of the front waist portion 20f, and the engagement strength of the tab 30 can be increased.
　なお、ナプキン１をパッケージから取り出した初期状態が図２２の状態である場合、初期状態、かつ、自然状態のナプキン１にて、位置の比較を行う。初期状態が図２２の状態でない場合（例えばタブ３０が折り畳まれている場合等）は、自然状態のナプキン１（自然状態の胴回り部材２０）に対して、サイド接合部４０等から幅方向の内側に向かって広げたタブ３０を前胴回り部２０ｆに係合した状態で、位置の比較を行う。 In addition, when the initial state of the napkin 1 taken out of the package is the state of FIG. 22, the positions of the napkin 1 in the initial state and the natural state are compared. When the initial state is not the state of FIG. 22 (for example, when the tab 30 is folded), the width direction inner side from the side joint 40 etc. with respect to the napkin 1 in the natural state (the waist member 20 in the natural state) The positions are compared with the tab 30 extending toward the front waist portion 20f engaged with the front waist portion 20f.
　また、ナプキン１は成人用のパンツ型吸収性物品であるが、図２２に示すように、前胴回り部２０ｆ、及び、サイド接合部４０の縦方向の長さＬ１，Ｌ２が比較的に短い。具体的には、サイド接合部４０に接合されたタブ３０が幅方向の内側に閉じられた状態で前胴回り部２０ｆの非肌側面に係合している、自然状態のナプキン１において、前胴回り部２０ｆ、及び、サイド接合部４０の縦方向の長さＬ１，Ｌ２を以下とする。まず、幅方向の位置がタブ３０と重複する、前胴回り部２０ｆの部位２０ｆＣの、縦方向の最小長さＬ１を、８０ｍｍ以上１５０ｍｍ以下とする。また、タブ３０が接合されているサイド接合部４０の縦方向の長さＬ２を、１００ｍｍ以上１６０ｍｍ以下とする。 Also, the napkin 1 is a pants-type absorbent article for adults, but as shown in FIG. 22, the longitudinal lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 are relatively short. Specifically, in the napkin 1 in the natural state, in which the tabs 30 joined to the side joints 40 are closed inward in the width direction and are engaged with the non-skin side surface of the front waistline portion 20f, the front waistline The vertical lengths L1 and L2 of the portion 20f and the side joint portion 40 are as follows. First, the minimum longitudinal length L1 of the portion 20fC of the front waist portion 20f that overlaps the tab 30 in the width direction is set to 80 mm or more and 150 mm or less. Further, the vertical length L2 of the side joint portion 40 to which the tab 30 is joined is set to 100 mm or more and 160 mm or less.
　タブ３０と重なる前胴回り部２０ｆの部位２０ｆＣは、タブ３０を開いて前胴回り部２０ｆを破いた着用者によって、図１５Ｃに示すように把持されやすい部位である。そのため、その部位２０ｆＣの縦方向の長さＬ１を比較的に短くすることで、着用者はその部位２０ｆＣを把持しやすく、太腿の前に前胴回り部２０ｆを引っ張りやすくなる。また、図１６Ｄに示すように、太腿の上の前胴回り部２０ｆを上から手で押さえる際に、前胴回り部２０ｆの縦方向の広範囲を手で押さえることができ、前胴回り部２０ｆの位置が安定した状態でタブ３０を係合できる。 A portion 20fC of the front waist portion 20f that overlaps with the tab 30 is a portion that is likely to be gripped by the wearer who has opened the tab 30 to tear the front waist portion 20f, as shown in FIG. 15C. Therefore, by making the longitudinal length L1 of the portion 20fC relatively short, the wearer can easily grasp the portion 20fC and pull the front waist portion 20f in front of the thigh. In addition, as shown in FIG. 16D, when the front waist portion 20f on the thigh is pressed from above with the hand, the front waist portion 20f can be pressed over a wide range in the vertical direction, and the position of the front waist portion 20f can be adjusted. can engage the tab 30 in a stable state.
　人工知能研究センターによる日本人の手の寸法データの調査結果によると、親指と人差し指の付け根から、人差し指の先端までの長さの平均値が、女性の場合に１００．６ｍｍであり、男性の場合に１０９.７ｍｍであり、両性（男性及び女性）の場合に１０７ｍｍであった。そのため、前胴回り部２０ｆの上記の寸法Ｌ１を１５０ｍｍ以下とすることで、着用者は、前胴回り部２０ｆの縦方向の半分の長さ以上を把持したり押さえたりすることができる。よって、安定してタブ３０を係合でき、ナプキン１の装着性が向上する。 According to the results of a survey of Japanese hand size data by the Artificial Intelligence Research Center, the average length from the base of the thumb and index finger to the tip of the index finger is 100.6 mm for women and 100.6 mm for men. 109.7 mm for both sexes (male and female) and 107 mm for both sexes. Therefore, by setting the dimension L1 of the front waist portion 20f to 150 mm or less, the wearer can hold or hold the front waist portion 20f for more than half the length in the vertical direction. Therefore, the tab 30 can be stably engaged, and the wearability of the napkin 1 is improved.
　一方で、胴回り部材２０は幅方向に伸縮する部材であり、着用者の胴回りにフィットする。そのため、前胴回り部２０ｆの上記の寸法Ｌ１を８０ｍｍ以上とし、短くし過ぎないことが好ましい。そうすることで、ナプキン１のずれ落ちを防止でき、着用者がナプキン１を安心して利用できる。 On the other hand, the waist member 20 is a member that expands and contracts in the width direction and fits the wearer's waist. Therefore, it is preferable that the above-described dimension L1 of the front waist portion 20f is set to 80 mm or more and not too short. By doing so, the napkin 1 can be prevented from slipping down, and the wearer can use the napkin 1 with peace of mind.
　また、サイド接合部４０の縦方向の長さＬ２も、前胴回り部２０ｆと同様に短くすることで、サイド接合部４０に接合されるタブ３０の縦方向の長さも短くなる。よって、図１５Ｃに示すように、着用者がタブ３０を把持しやすくなる。ただし、サイド接合部４０の縦方向の長さＬ２は、前胴回り部２０ｆの縦方向の長さＬ１よりも若干長くなることが好ましく、１００ｍｍ以上１６０ｍｍ以下の範囲とする。そうすることで、図１５Ｃに示すように着用者がタブ３０を持って太腿の下からナプキン１を引き上げる際に、縦方向に長いサイド接合部４０によって、ナプキン１の後方部の縦方向の広範囲に引き上げ力が伝わりやすくなる。よって、太腿の下からナプキン１の後方部を引き上げやすくなる。しかし、これに限定されず、前胴回り部２０ｆとサイド接合部４０の縦方向の長さＬ１，Ｌ２が等しくてもよい。 In addition, by shortening the length L2 of the side joints 40 in the vertical direction as well as the front waistline portion 20f, the length of the tab 30 joined to the side joints 40 in the vertical direction is also shortened. Therefore, as shown in FIG. 15C, it becomes easier for the wearer to grip the tab 30 . However, the vertical length L2 of the side joint portion 40 is preferably slightly longer than the vertical length L1 of the front waist portion 20f, and is in the range of 100 mm or more and 160 mm or less. 15C, when the wearer holds the tab 30 and lifts the napkin 1 from under the thigh, the longitudinally long side joints 40 allow the longitudinally extending rear portion of the napkin 1 to be pulled up. Pulling force can be easily transmitted over a wide range. Therefore, it becomes easier to pull up the rear part of the napkin 1 from under the thigh. However, the present invention is not limited to this, and the longitudinal lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 may be equal.
　このように、前胴回り部２０ｆ及びサイド接合部４０の長さＬ１，Ｌ２を短くすることで、着用者が自分でナプキン１を装着する場合の装着性が向上する。自分で装着する着用者を対象とした成人用のパンツ型吸収性物品（例えば本実施形態のナプキン１や軽失禁用のおむつ等）の場合、介護用のパンツ型吸収性物品に比べて、吸収性コア１１が小さく、排泄後の吸収性コア１１も軽い。そのため、前胴回り部２０ｆ及びサイド接合部４０の長さＬ１，Ｌ２を短くしても、パンツ型吸収性物品のずれ落ちの恐れが少ない。 By shortening the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 in this manner, the wearability of the napkin 1 is improved when the wearer wears the napkin 1 by himself/herself. In the case of an adult pants-type absorbent article (for example, the napkin 1 of the present embodiment, a diaper for light incontinence, etc.) intended for a wearer who wears it by himself, compared to a nursing pants-type absorbent article, the absorption The absorbent core 11 is small, and the absorbent core 11 after excretion is also light. Therefore, even if the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40 are shortened, the pants-type absorbent article is less likely to slide down.
　さらに、前胴回り部２０ｆ及びサイド接合部４０の長さＬ１，Ｌ２を短くすることで、図１６Ｂに示すように、太腿にナプキン１を巻き付けた際に、ナプキン１（特に吸収性本体１０）が垂れ下がり難くなる。よって、ナプキン１が便器に接触し難く、衛生的に使用できる。また、下着に近い形状となるため、ナプキン１の外観も向上する。 Furthermore, by shortening the lengths L1 and L2 of the front waist portion 20f and the side joint portions 40, as shown in FIG. becomes difficult to hang down. Therefore, the napkin 1 is less likely to come into contact with the toilet and can be used hygienically. Moreover, since the napkin 1 has a shape similar to underwear, the appearance of the napkin 1 is also improved.
