Description

吸収性物品Absorbent article
　本開示は吸収性物品に関する。 This disclosure relates to absorbent articles.
　液透過性の表面シートと、防漏性の裏面シートと、これらシートの間に配置される吸収体と、を備える、使い捨てオムツのような吸収性物品が公知である（例えば、特許文献１参照）。特許文献１の裏面シートは、ヒートロール不織布と液不透過性シートとを、接着剤を介して貼り合わせた積層シートに、エンボス処理により融着部を形成することにより、得られる。この場合、接着剤は積層シートの全体に適用されており、融着部は積層シートの全体に形成されている。 An absorbent article such as a disposable diaper, comprising a liquid-permeable front sheet, a leak-proof back sheet, and an absorber arranged between the sheets is known (see, for example, Patent Document 1). ). The back sheet of Patent Document 1 is obtained by forming a fused portion by embossing on a laminated sheet in which a heat-rolled non-woven fabric and a liquid-impermeable sheet are bonded together via an adhesive. In this case, the adhesive is applied to the entire laminated sheet, and the fused portion is formed on the entire laminated sheet.

　ところで、取扱者（例えば、親）が着用者（例えば、子）のために吸収性物品（例えば、使い捨てオムツ）を包装袋から取り出すときに、取扱者は吸収性物品の外面に触れる。したがって、着用者だけでなく、取扱者に対しても、柔らかい肌触りを提供するのが好ましい。しかしながら、特許文献１の吸収性物品の外面には、接着剤が全体的に適用され融着部が全体的に形成された積層シートが用いられる。このため、吸収性物品の外面に柔らかい肌触りを付与するのは困難である。 By the way, when the handler (eg, parent) takes out the absorbent article (eg, disposable diaper) from the packaging bag for the wearer (eg, child), the handler touches the outer surface of the absorbent article. Therefore, it is preferable to provide a soft touch not only to the wearer but also to the handler. However, on the outer surface of the absorbent article of Patent Document 1, a laminated sheet is used in which an adhesive is applied as a whole and a fused portion is formed as a whole. Therefore, it is difficult to give a soft touch to the outer surface of the absorbent article.

[Structure 1]
It is an absorbent article
Absorber and
A liquid-impermeable backsheet placed on the non-skin side of the absorber,
An exterior sheet arranged on the non-skin side of the back sheet and formed of a non-woven fabric,
Including
In the first overlapping region where the exterior sheet and the back sheet overlap each other when viewed in the article thickness direction,
A first joining region in which the exterior sheet and the back sheet are joined to each other,
A first non-bonded region in which the exterior sheet and the back sheet are not bonded to each other,
Is partitioned,
The first joint region includes a plurality of first widthwise extending joint regions that expand in the article width direction while being separated from each other in the article length direction in the deployed state.
The first non-joint region is located between the first widthwise extending joint regions in the unfolded state in the article length direction.
Within the first non-bonded region, the exterior sheet is slipperable with respect to the backsheet at least in the width direction of the article.
Absorbent article.
　吸収性物品の外面の肌触りについて本願発明者らが鋭意研究した結果、以下の２点が判明した。すなわち、１つ目は、別のシートに重ねられた不織布を指で押し付けながら、指を面内方向（不織布の表面に平行な方向）に移動させたときに、不織布が別のシートに対し面内方向にスリップ又は相対移動すると、柔らかい肌触りが得られる、ということである。この肌触りは、互いに重ねられた２枚のガーゼシートを２本の指で摘んで擦り合わせたときに得られる肌触りに似ていると考えられている。２つ目は、取扱者が吸収性物品を例えば包装袋から取り出すために吸収性物品を掴んだときに、取扱者の指、例えば親指が物品長さ方向を向く傾向にあり、したがって取扱者の親指が物品幅方向に動く傾向にある、ということである。 As a result of diligent research by the inventors of the present application on the texture of the outer surface of the absorbent article, the following two points were found. That is, the first is that when the non-woven fabric laminated on another sheet is pressed with a finger and the finger is moved in the in-plane direction (direction parallel to the surface of the non-woven fabric), the non-woven fabric faces the other sheet. It means that slipping or relative movement inward gives a soft touch. This feel is thought to be similar to the feel obtained when two gauze sheets stacked on top of each other are picked and rubbed with two fingers. Second, when the handler grabs the absorbent article, eg, to remove it from the packaging bag, the handler's fingers, such as the thumb, tend to point in the direction of the article length, and thus the handler's. It means that the thumb tends to move in the width direction of the article.
　構成１によれば、第１の非接合領域内の外装シートがバックシートに対し物品幅方向にスリップ可能である。その結果、取扱者が吸収性物品を掴んだときに取扱者の親指が物品幅方向に動くと、第１の非接合領域において外装シートがバックシートに対し物品幅方向にスリップ又は相対移動する。したがって、吸収性物品の外面に柔らかい肌触りが得られる。しかも、第１の非接合領域が第１の幅方向延在固定領域同士の間に位置するので、第１の非接合領域が物品幅方向に容易にスリップする。したがって、柔らかい肌触りが容易に得られる。 According to the configuration 1, the exterior sheet in the first non-bonded region can slip in the width direction of the article with respect to the back sheet. As a result, when the operator's thumb moves in the article width direction when the handler grabs the absorbent article, the exterior sheet slips or moves relative to the back sheet in the article width direction in the first non-joining region. Therefore, a soft touch can be obtained on the outer surface of the absorbent article. Moreover, since the first non-joining region is located between the first widthwise extending fixed regions, the first non-joining region easily slips in the article width direction. Therefore, a soft touch can be easily obtained.

Therefore, in the embodiment according to the present disclosure, the soft touch of the exterior sheet 5 can be obtained in the first non-bonded region NB1. That is, the outer surface of the disposable diaper 1 is given a soft touch.
　図３に示されるように、本開示による実施形態では、展開状態において、１つの第１の幅方向延在接合領域Ｂ１Ｗは、第１の重なり領域１１の物品長さ方向Ｌの一端部に位置し、別の第１の幅方向延在接合領域Ｂ１Ｗは、第１の重なり領域１１の物品長さ方向Ｌの他端部に位置する。また、本開示による実施形態では、展開状態において、第１の非接合領域ＮＢ１の物品長さ方向寸法ＤＬＮＢ１は、第１の幅方向延在接合領域Ｂ１Ｗの物品長さ方向外縁Ｂ１ＷＬｅから第１の重なり領域１１の物品長さ方向縁１１Ｌｅまでの物品長さ方向寸法ＤＬＭＬよりも大きい。更に、本開示による実施形態では、展開状態において、第１の非接合領域ＮＢ１の物品長さ方向寸法ＤＬＮＢ１は、第１の幅方向延在接合領域Ｂ１Ｗの物品長さ方向寸法ＤＬＢ１Ｗよりも大きい。このようにすると、第１の非接合領域ＮＢ１の物品長さ方向寸法ＤＬＮＢ１を、より大きくすることが可能となる。その結果、外装シート５が物品幅方向Ｗに、より容易にスリップ可能となる。したがって、柔らかい肌触りがより容易に得られる。 As shown in FIG. 3, in the embodiment according to the present disclosure, in the deployed state, one first widthwise extending joint region B1W is located at one end of the first overlapping region 11 in the article length direction L. However, another first widthwise extending joint region B1W is located at the other end of the first overlapping region 11 in the article length direction L. Further, in the embodiment according to the present disclosure, in the deployed state, the article length direction dimension DLNB1 of the first non-joining region NB1 is the first from the article length direction outer edge B1WLe of the first width direction extending joining region B1W. It is larger than the article length direction dimension DLML up to the article length direction edge 11Le of the overlapping region 11. Further, in the embodiment according to the present disclosure, in the deployed state, the article length direction dimension DLNB1 of the first non-joining region NB1 is larger than the article length direction dimension DLB1W of the first width direction extending joining region B1W. In this way, the article length direction dimension DLNB1 of the first non-joining region NB1 can be made larger. As a result, the exterior sheet 5 can slip more easily in the article width direction W. Therefore, a soft touch can be obtained more easily.
　また、本開示による実施形態では、展開状態において、第１の非接合領域ＮＢ１の物品長さ方向寸法ＤＬＮＢ１は、第１の非接合領域ＮＢ１の物品幅方向寸法ＤＷＮＢ１よりも大きい。これによっても、外装シート５が物品幅方向Ｗに、より容易にスリップ可能となる。 Further, in the embodiment according to the present disclosure, in the deployed state, the article length direction dimension DLNB1 of the first non-joint region NB1 is larger than the article width direction dimension DWNB1 of the first non-joint region NB1. This also makes it easier for the exterior sheet 5 to slip in the article width direction W.
　更に、図３に示されるように、本開示による実施形態では、展開状態において、１つの第１の長さ方向延在接合領域Ｂ１Ｌは、第１の重なり領域１１の物品幅方向Ｗの一端部に位置し、別の第１の長さ方向延在接合領域Ｂ１Ｌは、第１の重なり領域１１の物品幅方向Ｗの他端部に位置する。また、本開示による実施形態では、展開状態において、第１の非接合領域ＮＢ１の物品幅方向寸法ＤＷＮＢ１は、第１の長さ方向延在接合領域Ｂ１Ｌの物品幅方向外縁Ｂ１ＬＷｅから第１の重なり領域１１の物品幅方向縁１１Ｗｅまでの物品幅方向寸法ＤＷＭＷよりも大きい。更に、本開示による実施形態では、展開状態において、第１の非接合領域ＮＢ１の物品幅方向寸法ＤＷＮＢ１は、第１の長さ方向延在接合領域Ｂ１Ｌの物品幅方向寸法ＤＷＢ１Ｌよりも大きい。このようにすると、第１の非接合領域ＮＢ１の物品幅方向寸法ＤＷＮＢ１を、より大きくすることが可能となる。その結果、外装シート５が物品長さ方向Ｌに、より容易にスリップ可能となる。したがって、柔らかい肌触りがより容易に得られる。 Further, as shown in FIG. 3, in the embodiment according to the present disclosure, in the deployed state, one first lengthwise extending joint region B1L is one end portion of the first overlapping region 11 in the article width direction W. The other first lengthwise extending joint region B1L is located at the other end of the first overlapping region 11 in the article width direction W. Further, in the embodiment according to the present disclosure, in the deployed state, the article width direction dimension DWNB1 of the first non-joining region NB1 is the first overlap from the article width direction outer edge B1LWe of the first lengthwise extending joining region B1L. It is larger than the article width direction dimension DWMW up to the article width direction edge 11 We of the region 11. Further, in the embodiment according to the present disclosure, in the deployed state, the article width direction dimension DWNB1 of the first non-joining region NB1 is larger than the article width direction dimension DWB1L of the first lengthwise extending joining region B1L. In this way, the article width direction dimension DWNB1 of the first non-joining region NB1 can be made larger. As a result, the exterior sheet 5 can slip more easily in the article length direction L. Therefore, a soft touch can be obtained more easily.
　別の実施形態（図示しない）では、第１の接合領域Ｂ１は、３つ以上の第１の幅方向延在接合領域Ｂ１Ｗを含む。更に別の実施形態（図示しない）では、第１の接合領域Ｂ１は、１又は３つ以上の第１の長さ方向延在接合領域Ｂ１Ｌを含む。第１の接合領域Ｂ１が第１の幅方向延在接合領域Ｂ１Ｗと第１の長さ方向延在接合領域Ｂ１Ｌとの両方を含むことにより、外装シート５が中間シート４ｂに確実に保持される。したがって、例えばファスニングテープ１ｄが誤って外装シート５に係合したときに、外装シート５が破損するのが制限される。すなわち、使い捨てオムツ１の強度が高められる。更に別の実施形態（図示しない）では、第１の接合領域Ｂ１は、第１の長さ方向延在接合領域Ｂ１Ｌを含まない。 In another embodiment (not shown), the first junction region B1 includes three or more first widthwise extending junction regions B1W. In yet another embodiment (not shown), the first junction region B1 includes one or more first lengthwise extending junction regions B1L. The exterior sheet 5 is reliably held by the intermediate sheet 4b because the first joint region B1 includes both the first widthwise extending joint region B1W and the first lengthwise extending joint region B1L. .. Therefore, for example, when the fastening tape 1d is erroneously engaged with the exterior sheet 5, the exterior sheet 5 is restricted from being damaged. That is, the strength of the disposable diaper 1 is increased. In yet another embodiment (not shown), the first junction region B1 does not include the first lengthwise extending junction region B1L.
　本開示による実施形態の第１の接合領域Ｂ１における接合は、ホットメルト接着剤のような接着剤によって得られる。一例では、図４に示されるように、ホットメルト接着剤ＨＭＡは、物品幅方向Ｗにわずかに互いに離間しつつ物品長さ方向Ｌにそれぞれ延びる基準線ＲＬに沿いつつ、波状に塗工される（オメガ塗工）。別の例（図示しない）では、ホットメルト接着剤ＨＭＡは、基準線に沿いつつ、らせん状（スパイラル塗工）又は点状（ドット塗工）に塗工される。なお、微視的に見れば、接着剤同士の間に、外装シート５と中間シート４ｂとが互いに接合されていない微小領域が形成されうる。しかしながら、この微小領域は第１の非接合領域ＮＢ１よりも圧倒的に小さく、ここでは上述したような外装シート５のスリップは生じない。一方、本開示による実施形態の第１の非接合領域ＮＢ１には、接着剤が含まれない。 The bonding in the first bonding region B1 of the embodiment according to the present disclosure is obtained by an adhesive such as a hot melt adhesive. In one example, as shown in FIG. 4, the hot melt adhesive HMA is applied in a wavy shape along a reference line RL extending in the article length direction L while being slightly separated from each other in the article width direction W. (Omega coating). In another example (not shown), the hot melt adhesive HMA is applied in a spiral (spiral coating) or dot pattern (dot coating) along a reference line. From a microscopic point of view, a minute region in which the exterior sheet 5 and the intermediate sheet 4b are not joined to each other may be formed between the adhesives. However, this minute region is overwhelmingly smaller than the first non-bonded region NB1, and the slip of the exterior sheet 5 as described above does not occur here. On the other hand, the first non-bonded region NB1 of the embodiment according to the present disclosure does not contain an adhesive.
　図５には、図１及び図２に示される本開示による実施形態の使い捨てオムツ１の、第１の接合領域Ｂ１及び第１の非接合領域ＮＢ１が、展開状態において模式的に示される。本開示による実施形態では、第１の接合領域Ｂ１は、２つの第１の幅方向延在接合領域Ｂ１Ｗと、３つの第１の長さ方向延在接合領域Ｂ１Ｌと、を含む。２つの第１の幅方向延在接合領域Ｂ１Ｗは、第１の重なり領域１１の物品長さ方向Ｌの両端部に位置する。一方、３つの第１の長さ方向延在接合領域Ｂ１Ｌは、第１の重なり領域１１の物品幅方向Ｗの両端部と、第１の重なり領域１１の物品幅方向Ｗの中央部と、に位置する。 FIG. 5 schematically shows the first joining region B1 and the first non-joining region NB1 of the disposable diaper 1 according to the present disclosure shown in FIGS. 1 and 2. In the embodiments according to the present disclosure, the first junction region B1 includes two first widthwise extending junction regions B1W and three first lengthwise extending junction regions B1L. The two first widthwise extending joint regions B1W are located at both ends of the first overlapping region 11 in the article length direction L. On the other hand, the three first lengthwise extending joint regions B1L are formed on both ends of the first overlapping region 11 in the article width direction W and the central portion of the first overlapping region 11 in the article width direction W. To position.
　なお、図５に示される実施形態では、第１の幅方向延在接合領域Ｂ１Ｗの物品長さ方向外縁Ｂ１ＷＬｅと第１の重なり領域１１の物品長さ方向縁１１Ｌｅとは互いに一致し、したがって物品長さ方向寸法ＤＬＭＬ（図３）はゼロである。また、図５に示される実施形態では、第１の長さ方向延在接合領域Ｂ１Ｌの物品幅方向外縁Ｂ１ＬＷｅと第１の重なり領域１１の物品幅方向縁１１Ｗｅとは互いに一致し、したがって物品幅方向寸法ＤＷＭＷ（図３）はゼロである。このようにすると、外装シート５が中間シート４ｂに確実に保持される。 In the embodiment shown in FIG. 5, the outer edge B1WLe in the article length direction of the first widthwise extending joint region B1W and the article length direction edge 11Le of the first overlapping region 11 coincide with each other, and therefore the article. The lengthwise dimension DLML (FIG. 3) is zero. Further, in the embodiment shown in FIG. 5, the outer edge B1LWe in the article width direction of the first lengthwise extending joint region B1L and the article width direction edge 11We of the first overlapping region 11 coincide with each other, and therefore the article width. The directional dimension DWMW (FIG. 3) is zero. In this way, the exterior sheet 5 is securely held by the intermediate sheet 4b.
　図６は、物品幅方向Ｗに延びる折り曲げ線ＦＬに沿って折り曲げられた二つ折り状態にある、本開示による実施形態の使い捨てオムツ１の模式的平面図を示している。本開示による実施形態では、折り曲げ線ＦＬは上述の長さ方向中心線ＣＬに一致する。図６に示されるように、本開示による実施形態では、二つ折り状態にある使い捨てオムツ１に、折り曲げ線ＦＬに近い近位区域ＰＲと、折り曲げ線ＦＬから遠い遠位区域ＤＳとが区画されている。図６では、近位区域ＰＲがドットとともに描かれている。本開示による実施形態では、近位区域ＰＲと遠位区域ＤＳとの境界線ＢＬは、二つ折り状態にある使い捨てオムツ１を物品長さ方向Ｌに二等分する。 FIG. 6 shows a schematic plan view of the disposable diaper 1 of the embodiment according to the present disclosure, which is in a folded state in half folded along a bending line FL extending in the width direction W of the article. In the embodiment according to the present disclosure, the bending line FL coincides with the above-mentioned center line CL in the length direction. As shown in FIG. 6, in the embodiment according to the present disclosure, the disposable diaper 1 in the folded state is divided into the proximal area PR near the folding line FL and the distal area DS far from the folding line FL. There is. In FIG. 6, the proximal area PR is drawn with dots. In the embodiment according to the present disclosure, the boundary line BL between the proximal area PR and the distal area DS bisects the disposable diaper 1 in the folded state in the article length direction L.
　本開示による実施形態では、第１の非接合領域ＮＢ１の少なくとも一部が近位区域ＰＲ内に位置している。一例では、図６に示されるように、第１の非接合領域ＮＢ１は、近位区域ＰＲ内及び遠位区域ＤＳ内に位置する。別の実施形態（図示しない）では、第１の非接合領域ＮＢ１は、遠位区域ＤＳ内に位置することなく、近位区域ＰＲ内に位置する。 In the embodiment according to the present disclosure, at least a part of the first non-junction region NB1 is located in the proximal zone PR. In one example, as shown in FIG. 6, the first non-junction region NB1 is located within the proximal zone PR and within the distal zone DS. In another embodiment (not shown), the first non-junction region NB1 is located within the proximal zone PR, rather than within the distal zone DS.
　本開示による実施形態の第１の非接合領域ＮＢ１の位置は次のように説明することもできる。すなわち、本開示による実施形態では、図７に示されるように、近位区域ＰＲ内に、使い捨てオムツ１の幅方向中心線ＣＷと、吸収体３の物品幅方向Ｗ外縁３ｅ，３ｅとによって、２つの近位区画部分ＰＲｐ，ＰＲｐが区画される。図７では、近位区画部分ＰＲｐ，ＰＲｐがドットとともに描かれている。 The position of the first non-junction region NB1 of the embodiment according to the present disclosure can also be explained as follows. That is, in the embodiment according to the present disclosure, as shown in FIG. 7, the width direction center line CW of the disposable diaper 1 and the article width direction W outer edges 3e and 3e of the absorber 3 are provided in the proximal area PR. Two proximal compartments PRp, PRp are partitioned. In FIG. 7, the proximal compartments PRp and PRp are drawn together with the dots.
　ここで、例えば図５に示される第１の非接合領域ＮＢ１の一部をＮＢ１ｐで表すと、本開示による実施形態では、各近位区域部分ＰＲｐに第１の非接合領域ＮＢ１ｐが位置している。この場合、第１の非接合領域ＮＢ１ｐの物品長さ方向寸法ＤＬｐは、第１の非接合領域ＮＢ１ｐの物品幅方向寸法ＤＷｐよりも大きい。なお、図７に示される第１の非接合領域ＮＢ１ｐは、第１の重なり領域１１に区画される第１の非接合領域ＮＢ１の一部である。別の実施形態（図示しない）では、図７に示される第１の非接合領域ＮＢ１ｐが、第１の重なり領域１１に区画される第１の非接合領域ＮＢ１の全部である。 Here, for example, when a part of the first non-junction region NB1 shown in FIG. 5 is represented by NB1p, in the embodiment according to the present disclosure, the first non-junction region NB1p is located in each proximal region portion PRp. There is. In this case, the article length direction dimension DLp of the first non-joining region NB1p is larger than the article width direction dimension DWp of the first non-joining region NB1p. The first non-junction region NB1p shown in FIG. 7 is a part of the first non-junction region NB1 partitioned by the first overlapping region 11. In another embodiment (not shown), the first non-junction region NB1p shown in FIG. 7 is the entire first non-junction region NB1 partitioned by the first overlapping region 11.
　本開示による実施形態では更に、図５に示されるように、物品厚さ方向Ｔに見て、第１の非接合領域ＮＢ１と吸収体３とが少なくとも部分的に重なっている。吸収体３の肌触りは柔らかい。したがって、取扱者が第１の非接合領域ＮＢ１を物品厚さ方向Ｔに押したときに、より柔らかい肌触りが得られる。 Further, in the embodiment according to the present disclosure, as shown in FIG. 5, the first non-junction region NB1 and the absorber 3 overlap at least partially in the article thickness direction T. The absorber 3 is soft to the touch. Therefore, when the handler pushes the first non-bonded region NB1 in the article thickness direction T, a softer feel is obtained.
　再び図１を参照すると、本開示による実施形態では、展開状態において、中間シート４ｂの物品長さ方向Ｌ寸法は、防漏シート４ａの物品長さ方向Ｌ寸法よりも小さい。また、本開示による実施形態では展開状態において、中間シート４ｂの物品幅方向Ｗ寸法は、防漏シート４ａの物品幅方向Ｗ寸法よりも小さい。したがって、本開示による実施形態では、物品厚さ方向Ｔに見て中間シート４ｂと防漏シート４ａとが互いに重なっている第２の重なり領域１２は、中間シート４ｂが拡がっている領域である。 Referring to FIG. 1 again, in the embodiment according to the present disclosure, the L dimension in the article length direction of the intermediate sheet 4b is smaller than the L dimension in the article length direction of the leak-proof sheet 4a in the unfolded state. Further, in the embodiment according to the present disclosure, the W dimension in the article width direction of the intermediate sheet 4b is smaller than the W dimension in the article width direction of the leak-proof sheet 4a in the deployed state. Therefore, in the embodiment according to the present disclosure, the second overlapping region 12 in which the intermediate sheet 4b and the leak-proof sheet 4a overlap each other in the article thickness direction T is a region in which the intermediate sheet 4b extends.
　本開示による実施形態では、第２の重なり領域１２の全体に、中間シート４ｂと防漏シート４ａとが互いに接合されている第２の接合領域Ｂ２が区画されている。言い換えると、中間シート４ｂ全体が防漏シート４ａに接合されている。図８には、本開示による実施形態の使い捨てオムツ１の、第２の接合領域Ｂ２が、展開状態において模式的に示される。図面では、第２の接合領域Ｂ２はハッチングとともに描かれている。第２の接合領域Ｂ２においては、第１の接合領域Ｂ１と同様に接着剤が適用される。 In the embodiment according to the present disclosure, a second joining region B2 in which the intermediate sheet 4b and the leak-proof sheet 4a are joined to each other is partitioned over the entire second overlapping region 12. In other words, the entire intermediate sheet 4b is joined to the leak-proof sheet 4a. FIG. 8 schematically shows the second joint region B2 of the disposable diaper 1 according to the present disclosure in the unfolded state. In the drawing, the second joint region B2 is drawn with hatching. In the second joining region B2, the adhesive is applied in the same manner as in the first joining region B1.
　図９には、本開示による実施形態の第１の接合領域Ｂ１及び第１の非接合領域ＮＢ１並びに第２の接合領域Ｂ２が模式的に示される。図５，８，９からわかるように、物品厚さ方向Ｔに見て、第１の接合領域Ｂ１は、第２の接合領域Ｂ２と重なっている。また、物品厚さ方向Ｔに見て、第１の非接合領域ＮＢ１も、第２の接合領域Ｂ２と重なっている。本開示による実施形態の第２の接合領域Ｂ２でも、第１の接合領域Ｂ１と同様に、接着剤が適用される。 FIG. 9 schematically shows a first junction region B1 and a first non-junction region NB1 and a second junction region B2 according to the present disclosure. As can be seen from FIGS. 5, 8 and 9, the first joint region B1 overlaps with the second joint region B2 when viewed in the article thickness direction T. Further, the first non-joining region NB1 also overlaps with the second joining region B2 when viewed in the article thickness direction T. In the second bonding region B2 of the embodiment according to the present disclosure, the adhesive is applied in the same manner as in the first bonding region B1.
　なお、本開示による実施形態の外装シート５は、物品長さ方向Ｌ及び物品幅方向Ｗに関し中間シート４ｂよりも外側において、防漏シート４ａ及びサイドフラップ６に接合される。 The exterior sheet 5 of the embodiment according to the present disclosure is joined to the leak-proof sheet 4a and the side flap 6 outside the intermediate sheet 4b in the article length direction L and the article width direction W.
　さて、取扱者（例えば、親）が着用者（例えば、子）のために吸収性物品（例えば、使い捨てオムツ）を包装袋から取り出すときに、取扱者は吸収性物品の外面に触れる。この場合、本願発明者らによれば、取扱者の指、例えば親指が物品長さ方向Ｌを向く傾向にあり、取扱者の親指が物品幅方向Ｗに動く傾向にあることが判明している。 Now, when the handler (eg, parent) removes the absorbent article (eg, disposable diaper) from the packaging bag for the wearer (eg, child), the handler touches the outer surface of the absorbent article. In this case, according to the inventors of the present application, it has been found that the operator's finger, for example, the thumb tends to face the article length direction L, and the handler's thumb tends to move in the article width direction W. ..
　すなわち、図１０に示されるように、取扱者が例えば包装袋から取り出すために使い捨てオムツ１を掴んだときに、取扱者の親指ＴＢが物品長さ方向Ｌを向く場合が多い。したがって、親指ＴＢは、図１０に矢印で示されるように、物品幅方向Ｗに動く場合が多い。この点、本開示による実施形態では、上述したように、第１の非接合領域ＮＢ１が中間シート４ｂに対し少なくとも物品幅方向Ｗにスリップ可能である。したがって、取扱者が使い捨てオムツ１と掴んで親指ＴＢを動かしたときに、取扱者は柔らかい肌触りを得ることができる。 That is, as shown in FIG. 10, when the handler grabs the disposable diaper 1 for taking out from the packaging bag, for example, the thumb TB of the handler often faces the article length direction L. Therefore, the thumb TB often moves in the article width direction W, as shown by the arrow in FIG. In this respect, in the embodiment according to the present disclosure, as described above, the first non-bonded region NB1 can slip at least in the article width direction W with respect to the intermediate sheet 4b. Therefore, when the handler grabs the disposable diaper 1 and moves the thumb TB, the handler can obtain a soft touch.
　しかも、本願発明者らによれば、取扱者が使い捨てオムツ１を掴んだときに、取扱者の親指ＴＢが近位区域ＰＲ内、特に近位区画部分ＰＲｐ内に位置する傾向にある、ことが判明している。この点、本開示による実施形態では、上述したように、近位区域ＰＲ内、特に近位区画部分ＰＲｐ内に、第１の非接合領域ＮＢ１が位置している。その結果、取扱者が使い捨てオムツ１を掴んだときに、取扱者の親指ＴＢが第１の非接合領域ＮＢ１に位置しやすい。したがって、柔らかい肌触りが確実に得られる。 Moreover, according to the inventors of the present application, when the handler grabs the disposable diaper 1, the thumb TB of the handler tends to be located in the proximal area PR, particularly in the proximal section PRp. It is known. In this regard, in the embodiment according to the present disclosure, as described above, the first non-junction region NB1 is located in the proximal region PR, particularly in the proximal compartment portion PRp. As a result, when the operator grabs the disposable diaper 1, the operator's thumb TB is likely to be located in the first non-joining region NB1. Therefore, a soft touch is surely obtained.
　なお、図７に示される第１の非接合領域ＮＢ１ｐの物品長さ方向寸法ＤＬｐは４０ｍｍ以上が好ましい。一方、第１の非接合領域ＮＢ１ｐの物品幅方向寸法ＤＷｐは２０ｍｍ以上が好ましい。第１の非接合領域ＮＢ１ｐの物品長さ方向寸法ＤＬｐが４０ｍｍ未満であるか、又は、第１の非接合領域ＮＢ１ｐの物品幅方向寸法ＤＷｐが２０ｍｍ未満であると、外装シート５が中間シート４ｂに対し有意にスリップ又は相対移動するのが困難となり、柔らかい肌触りを十分に得るのが困難となる。あるいは、使い捨てオムツ１を掴んだ取扱者の指が第１の非接合領域ＮＢ１ｐ内に位置するのが困難となる。 The article length direction dimension DLp of the first non-bonded region NB1p shown in FIG. 7 is preferably 40 mm or more. On the other hand, the article width direction dimension DWp of the first non-bonded region NB1p is preferably 20 mm or more. If the article length direction DLp of the first non-bonded region NB1p is less than 40 mm, or the article width direction dimension DWp of the first non-bonded region NB1p is less than 20 mm, the exterior sheet 5 is the intermediate sheet 4b. However, it becomes significantly difficult to slip or move relative to each other, and it becomes difficult to obtain a sufficient soft touch. Alternatively, it becomes difficult for the operator's finger holding the disposable diaper 1 to be located in the first non-joining region NB1p.
　また、本開示による実施形態では、外装シート５が、不織布から形成された、柔らかい肌触りの中間シート４ｂに対し、スリップ又は相対移動する。したがって、より柔らかな肌触りが得られる。しかも、例えばＳＢ不織布及びＳＭＳ不織布は、表面の毛羽立ちが比較的少ない。したがって、中間シート４ｂがＳＢ不織布又はＳＭＳ不織布から形成されると、外装シート５が中間シート４ｂに対しスムースにスリップ又は相対移動する。したがって、より柔らかい肌触りが得られる。これに対し、例えばエアスルー不織布は、表面の毛羽立ちが比較的多い。 Further, in the embodiment according to the present disclosure, the exterior sheet 5 slips or moves relative to the soft-touch intermediate sheet 4b formed of the non-woven fabric. Therefore, a softer touch can be obtained. Moreover, for example, SB non-woven fabric and SMS non-woven fabric have relatively little fluffing on the surface. Therefore, when the intermediate sheet 4b is formed of the SB non-woven fabric or the SMS non-woven fabric, the exterior sheet 5 slips or moves relative to the intermediate sheet 4b smoothly. Therefore, a softer touch can be obtained. On the other hand, for example, the air-through non-woven fabric has a relatively large amount of fluff on the surface.
　更に、本開示による実施形態では、図８，９に示されるように、中間シート４ｂ全体が防漏シート４ａに接合される。したがって、使い捨てオムツ１の強度が高められる。すなわち、本開示による実施形態では、使い捨てオムツ１の柔らかい肌触りが得られるとともに、使い捨てオムツ１の強度が高められる。 Further, in the embodiment according to the present disclosure, as shown in FIGS. 8 and 9, the entire intermediate sheet 4b is joined to the leak-proof sheet 4a. Therefore, the strength of the disposable diaper 1 is increased. That is, in the embodiment according to the present disclosure, the soft touch of the disposable diaper 1 is obtained, and the strength of the disposable diaper 1 is enhanced.
　更に、本開示による実施形態では、第１の接合領域Ｂ１及び第２の接合領域Ｂ２と、インジケーター７とが、物品厚さ方向Ｔに見て、少なくとも部分的に互いに重なっている。インジケーター７の外側又は非肌側に位置する防漏シート４ａ、中間シート４ｂ及び外装シート５が互いに物品厚さ方向Ｔに離間していると、これら防漏シート４ａ、中間シート４ｂ及び外装シート５によって、インジケーター７の視認性が低下するおそれがある。本開示による実施形態では、物品厚さ方向Ｔに見てインジケーター７と重なっている外装シート５、中間シート４ｂ及び防漏シート４ａが互いに接合されており、互いに密着されている。その結果、インジケーター７の良好な視認性が確保される。 Further, in the embodiment according to the present disclosure, the first joint region B1 and the second joint region B2 and the indicator 7 are at least partially overlapped with each other when viewed in the article thickness direction T. When the leak-proof sheet 4a, the intermediate sheet 4b and the exterior sheet 5 located on the outside or the non-skin side of the indicator 7 are separated from each other in the article thickness direction T, the leak-proof sheet 4a, the intermediate sheet 4b and the exterior sheet 5 are separated from each other. This may reduce the visibility of the indicator 7. In the embodiment according to the present disclosure, the exterior sheet 5, the intermediate sheet 4b, and the leak-proof sheet 4a, which overlap with the indicator 7 when viewed in the article thickness direction T, are joined to each other and are in close contact with each other. As a result, good visibility of the indicator 7 is ensured.
　また、図５に示されるように、本開示による実施形態では、ＬＧ弾性部材８に隣接する外装シート５の部分が第１の長さ方向延在領域Ｂ１Ｌにより中間シート４ｂに接合される。更に、ＷＧ弾性部材１０に隣接する外装シート５の部分が第１の幅方向延在領域Ｂ１Ｗにより中間シート４ｂに接合される。この場合、外装シート５の当該部分が中間シート４ｂに接合されていないと、弾性部材８，１０が収縮したときに、外装シート５の当該部分に比較的大きなシワが形成されるおそれがある。本開示による実施形態では、外装シート５の当該部分にシワが形成されるが制限される。したがって、使い捨てオムツ１の良好な外観が確保される。 Further, as shown in FIG. 5, in the embodiment according to the present disclosure, the portion of the exterior sheet 5 adjacent to the LG elastic member 8 is joined to the intermediate sheet 4b by the first lengthwise extending region B1L. Further, the portion of the exterior sheet 5 adjacent to the WG elastic member 10 is joined to the intermediate sheet 4b by the first widthwise extending region B1W. In this case, if the portion of the exterior sheet 5 is not joined to the intermediate sheet 4b, relatively large wrinkles may be formed in the portion of the exterior sheet 5 when the elastic members 8 and 10 contract. In the embodiment according to the present disclosure, wrinkles are formed in the portion of the exterior sheet 5 but are limited. Therefore, a good appearance of the disposable diaper 1 is ensured.
　図１１及び図１２は、本開示による別の実施形態を示している。本開示による別の実施形態では、第２の重なり領域１２に、中間シート４ｂと防漏シート４ａとが互いに接合されている第２の接合領域Ｂ２と、中間シート４ｂと防漏シート４ａとが互いに接合されていない第２の非接合領域ＮＢ２と、が区画されている。 11 and 12 show another embodiment according to the present disclosure. In another embodiment according to the present disclosure, in the second overlapping region 12, a second joint region B2 in which the intermediate sheet 4b and the leak-proof sheet 4a are joined to each other, and the intermediate sheet 4b and the leak-proof sheet 4a are provided. A second non-junction region NB2, which is not joined to each other, is partitioned.
　本開示による別の実施形態では、第２の非接合領域ＮＢ２内において、中間シート４ｂは防漏シート４ａに対し少なくとも物品幅方向Ｗにスリップ又は相対移動可能である。このようなスリップ又は相対移動が生じるのは、主として、第２の非接合領域ＮＢ２内に位置する中間シート４ｂがたるみ又はドレープを有しているからである。その結果、取扱者が使い捨てオムツ１の外面に触れたときに、第１の非接合領域ＮＢ１内の外装シート５が中間シート４ｂに対しスリップ又は相対移動するだけでなく、第２の非接合領域ＮＢ２内の中間シート４ｂが防漏シート４ａに対しスリップ又は相対移動する。したがって、より柔らかい肌触りが得られる。 In another embodiment according to the present disclosure, within the second non-joining region NB2, the intermediate sheet 4b can slip or move relative to the leak-proof sheet 4a at least in the article width direction W. Such slip or relative movement occurs mainly because the intermediate sheet 4b located in the second non-bonded region NB2 has slack or drape. As a result, when the operator touches the outer surface of the disposable diaper 1, not only the exterior sheet 5 in the first non-joining region NB1 slips or moves relative to the intermediate sheet 4b, but also the second non-joining region The intermediate sheet 4b in the NB2 slips or moves relative to the leak-proof sheet 4a. Therefore, a softer touch can be obtained.
　更に、本開示による別の実施形態では、物品厚さ方向Ｔに見て、第１の非接合領域ＮＢ１と第２の非接合領域ＮＢ２とが少なくとも部分的に互いに重なっており、第１の接合領域Ｂ１と第２の接合領域Ｂ２とが少なくとも部分的に互いに重なっている。図１１及び図１２に示される実施形態では、物品厚さ方向Ｔに見て、第２の接合領域Ｂ２の全部が第１の接合領域Ｂ１と重なっており、第２の非接合領域ＮＢ２の全部が第１の非接合領域ＮＢ１と重なっている。 Further, in another embodiment according to the present disclosure, the first non-joining region NB1 and the second non-joining region NB2 overlap each other at least partially in the article thickness direction T, and the first joining region NB1 The region B1 and the second junction region B2 overlap each other at least partially. In the embodiment shown in FIGS. 11 and 12, when viewed in the article thickness direction T, all of the second joint region B2 overlaps with the first joint region B1 and all of the second non-joint region NB2. Overlaps the first non-junction region NB1.
　その結果、中間シート４ｂに対しスリップ可能な外装シート５の部分と、防漏シート４ａに対しスリップ可能な中間シート４ｂの部分とが、物品厚さ方向Ｔに互いに整列される。あるいは、第２の非接合領域ＮＢ２内において、防漏シート４ａに対する中間シート４ｂのスリップが、外装シート５によって制限されない。あるいは、したがって、より柔らかい肌触りが得られる。 As a result, the portion of the exterior sheet 5 slipperable with respect to the intermediate sheet 4b and the portion of the intermediate sheet 4b slipperable with respect to the leak-proof sheet 4a are aligned with each other in the article thickness direction T. Alternatively, within the second non-bonded region NB2, the slip of the intermediate sheet 4b with respect to the leak-proof sheet 4a is not limited by the exterior sheet 5. Alternatively, therefore, a softer feel is obtained.
　図１３及び図１４は、本開示による更に別の実施形態を示している。本開示による更に別の実施形態では、物品厚さ方向Ｔに見て、第１の非接合領域ＮＢ１と第２の接合領域Ｂ２とが少なくとも部分的に互いに重なっており、かつ、第１の接合領域Ｂ１と第２の非接合領域ＮＢ２とが少なくとも部分的に互いに重なっている。図１３及び図１４に示される実施形態では、物品厚さ方向Ｔに見て、第２の接合領域Ｂ２の一部（領域Ｂ２Ｚ以外）が第１の非接合領域ＮＢ１と重なっており、第２の非接合領域ＮＢ２の全部が第１の接合領域Ｂ１と重なっている。 13 and 14 show yet another embodiment according to the present disclosure. In yet another embodiment according to the present disclosure, the first non-joining region NB1 and the second joining region B2 are at least partially overlapped with each other and the first joining region B2 is viewed in the article thickness direction T. The region B1 and the second non-junction region NB2 overlap each other at least partially. In the embodiment shown in FIGS. 13 and 14, a part of the second bonding region B2 (other than the region B2Z) overlaps with the first non-bonding region NB1 when viewed in the article thickness direction T, and the second All of the non-junction region NB2 of the above overlaps with the first junction region B1.
　その結果、中間シート４ｂに対しスリップ可能な外装シート５の部分と、防漏シート４ａに接合された中間シート４ｂの部分とが、物品厚さ方向Ｔに互いに整列され、中間シート４ｂに接合された外装シート５の部分と、防漏シート４ａに対しスリップ可能な中間シート４ｂの部分とが、物品厚さ方向Ｔに互いに整列される。あるいは、第２の非接合領域ＮＢ２内において、防漏シート４ａに対する中間シート４ｂのスリップが、外装シート５によって制限されうる。したがって、柔らかい肌触りが提供されつつ、使い捨てオムツ１の強度が高められる。 As a result, the portion of the exterior sheet 5 slipperable to the intermediate sheet 4b and the portion of the intermediate sheet 4b joined to the leak-proof sheet 4a are aligned with each other in the article thickness direction T and joined to the intermediate sheet 4b. The portion of the exterior sheet 5 and the portion of the intermediate sheet 4b slippable with respect to the leak-proof sheet 4a are aligned with each other in the article thickness direction T. Alternatively, within the second non-bonded region NB2, the slip of the intermediate sheet 4b with respect to the leak-proof sheet 4a can be limited by the exterior sheet 5. Therefore, the strength of the disposable diaper 1 is increased while providing a soft touch.
　なお、使い捨てオムツ１の外面の肌触りは、図１１及び図１２に示される実施形態、図１３及び図１４に示される実施形態、図８及び９に示される実施形態の順に柔らかい。一方、使い捨てオムツ１の強度は、図８及び９に示される実施形態、図１３及び図１４に示される実施形態、図１１及び図１２に示される実施形態の順に高い。 The outer surface of the disposable diaper 1 is soft to the touch in the order of the embodiments shown in FIGS. 11 and 12, the embodiments shown in FIGS. 13 and 14, and the embodiments shown in FIGS. 8 and 9. On the other hand, the strength of the disposable diaper 1 is higher in the order of the embodiment shown in FIGS. 8 and 9, the embodiment shown in FIGS. 13 and 14, and the embodiment shown in FIGS. 11 and 12.
　別の実施形態（図示しない）では、バックシート４は中間シート４ｂを含むことなく、防漏シート４ａを含む。したがって、バックシート４が中間シート４ｂを含む実施形態と含まない実施形態とを包含するように表現すると、本開示による実施形態の吸収性物品１は、物品厚さ方向Ｔに見て外装シート５とバックシート４とが互いに重なっている第１の重なり領域１１に、外装シート５とバックシート４とが互いに接合されている第１の接合領域Ｂ１と、外装シート５とバックシート４とが互いに接合されてない第１の非接合領域ＮＢ１と、が区画されており、第１の接合領域Ｂ１が、展開状態において物品長さ方向Ｌに互いに離間しつつ物品幅方向Ｗにそれぞれ拡がる、複数の第１の幅方向延在接合領域Ｂ１Ｗを含み、第１の非接合領域ＮＢ１が、展開状態において物品長さ方向Ｌに関し第１の幅方向延在接合領域Ｂ１Ｗ同士の間に位置し、第１の非接合領域ＮＢ１内において、外装シート５がバックシート４に対し少なくとも物品幅方向Ｗにスリップ可能である、吸収性物品１である、ということになる。 In another embodiment (not shown), the backsheet 4 does not include the intermediate sheet 4b, but includes the leakproof sheet 4a.
