Yes. Then, by applying an adhesive such as a hot melt adhesive (HMA) to a predetermined range in the joining target region H between the two sheet members stacked in the thickness direction, the two sheet members A joint 50 is formed to join the two together. Similarly, a joining target region H for joining both sheets is provided between the first sheet member and the third sheet member, and a joining portion 50 is formed in the joining target region H.
- HMA hot melt adhesive
- HMA is applied to the entire range of the bonding target region H with respect to at least one of the first sheet member and the second sheet member. That is, the joint portion 50 is formed in a substantially rectangular strip shape along the vertical direction within a range equivalent to the joining target region H.
- a coating pattern is referred to as a “coater pattern”.
- the coater pattern two sheet members can be firmly bonded to each other, which is suitable when it is desired to ensure the bonding strength.
- the shape of the bonding portion 50 is not limited to the coater pattern, and the bonding portion 50 can be formed in various patterns other than the coater pattern by changing the HMA coating pattern within the bonding target region H. It is.

- FIG. 9 shows a case where a uniform force is applied in the lateral direction to the first to third sheet members.
- the force acting on each sheet member is often uneven, and the amount of displacement of the positions of the holes 17h in the lateral direction is different. Becomes less noticeable. Thereby, the cut line 17 becomes inconspicuous, and it is possible to make it difficult for the user to feel uneasy.
- seat 24 which are located in the both outer sides of the thickness direction are comprised with the nonwoven fabric.
- the surface is in a fuzzy state. Therefore, since the hole edge 17he of the hole 17h formed in the skin side sheet 26 and the back sheet 24 is also fuzzy, the outer edge (edge) of the hole 17h is less noticeable.
- the sheet members arranged on the outer side (in the above example, the second sheet member and the third sheet member) among the plurality of overlapping sheet members are made of nonwoven fabric or the like, thereby making the holes 17h more conspicuous. Can be difficult.
- FIG. 10 is a diagram illustrating an example in which the joining target region H and the hole edge portion 17he overlap.
- the joining part 50 is formed in the joining object area
- the omega pattern or spiral pattern.
- the joining portion 50 that joins the overlapped sheet members and at least one hole edge portion 17he among the plurality of hole edge portions 17he are not overlapped. Thereby, the hole 17h penetrating the sheet member becomes difficult to visually recognize, and the cut line 17 becomes less conspicuous.
- FIGS. 11A and 11B are diagrams illustrating an example in which the hole edge portion 17he and the joint portion 50 overlap between the first sheet member and the second sheet member.
- the hole edge portion 17he and the joint portion 50 do not overlap between the first sheet member (leakproof sheet 23) and the third sheet member (back sheet 24). Between the first sheet member (leakproof sheet 23) and the second sheet member (skin-side sheet 26), the hole edge 17he and the joint 50 overlap.
- FIG. 11B shows a case where a lateral force is applied to the sheet member in the state of FIG. 11A. In this case, as described with reference to FIG. 9, there is a large shift in the lateral position of the hole 17h between the first sheet member and the third sheet member.
- the hole edge 17he which is the outer edge of the hole 17h, is joined to each other between the first sheet and the second sheet, the displacement amount of the lateral position of the hole 17h is small, and the hole 17h is visible. It is easy to do. That is, the cut line 17 is not noticeable when viewed from the non-skin side (back sheet 24 side) of the diaper 1, but the cut line 17 is easily noticeable when viewed from the skin side (skin side sheet 26 side) of the diaper 1. Become.

<使い捨ておむつ1の基本構成>
本実施形態の使い捨ておむつ1(以下、単におむつ1とも呼ぶ)は、主に新生児や乳幼児を着用対象とした使い捨ておむつであり、体重が3000g以下の低体重児、特に体重が2500g未満の低出生体重児に好適に用いられる。なお、低体重児には、低出生体重児(体重2500g未満)だけでなく、極低出生体重児用(体重1500g未満)や超低出生体重児用(体重1000g未満)も含まれる。 === Embodiment ===

The detailed structure of the
切り取り線17はおむつ1の着用時において、着用者の脇腹部の視認しやすい位置に配置されている。そして、おむつ1の着用時には、サイドフラップ14が横方向に引き伸ばされるような力を受けるため、切り取り線17を構成する孔17hにも横方向の力が作用して各々の孔17が広がりやすくなり、外観上目立ちやすくなる。特に、着用者が低体重児であり、図3に示されるようなポジショニング姿勢を取っている場合には、仰向け姿勢の場合と比較してファスニングテープ30の係合部に横方向の力がかかりやすくなり、ミシン目状に連なった孔17hが過度に強調されてしまう場合がある。孔17hが過度に目立つと、おむつ1に穴が開いているような印象を使用者に与え、当該孔17h部分から排泄物がおむつ1の外部に漏出してしまうのではないかという不安を生じさせるおそれがある。また、孔17hの部分からおむつ1が破れてしまうのではないかという不安を生じさせることも考えられ、おむつ1を安心して使用することの妨げとなる。 <Appearance of cut line>
