Description
図1は、本実施の形態において使い捨ておむつを構成する使い捨ておむつ1の概略斜視図である。図2は、本実施の形態に係る使い捨ておむつ1の展開平面図である。図3は、図2に示すX1−X’1線に沿った使い捨ておむつ1の幅方向断面図である。図4は、図2に示すX2−X’2線に沿った使い捨ておむつ1の前後方向断面図である。使い捨ておむつ1は、パンツ型の使い捨ておむつである。
なお、中央弾性材及び弾性材被覆シートの配置方法については、後述にて詳細に説明する。
図5は、吸収体40の平面図である。図5に示すように、吸収体40は、第1層41と、第1層41と重ねられる第2層42とを有する。第1層41は、着用者の非肌当接面側に位置し、第2層42は、着用者の肌当接面側に位置する。
図6は、使い捨ておむつ1の着用状態を模式的に示す断面図(図1のX1−X’1線基準)である。使い捨ておむつ1が着用されると、吸収体の股下領域S3は、着用者の股間に当てられる。着用者の脚等によって、吸収体には、幅方向外側から幅方向内側に向かって力が掛かる。吸収体40は、中央弾性材44及び中央スリット45と、サイドスリット46と、を基点として吸収体40が曲がり、使い捨ておむつ1の幅方向Wに沿った断面形状は、波状に変形する。よって、吸収体40の股下領域S3は、規則的に折り畳まれた状態となる。
本実施の形態に係る吸収性物品の製造方法の一例について説明する。図7は、吸収性物品の製造方法を説明するための図であり、吸収性物品が製造されている過程の一部を示している。図7は、製造過程における構成部品の搬送する方向を搬送方向MDとして示し、当該搬送方向と交差する方向を交差方向CDとして示す。吸収性物品の製造方法は、吸収性物品1が幅方向において連続した状態で製造する。
次いで、変形例に係る使い捨ておむつについて、図10を参照しながら説明する。なお、以下の実施の形態において、上述の実施の形態と同様の構成については、同一の符号を付して説明を省略する。
上述したように、本発明の実施の形態を通じて本発明の内容を開示したが、この開示の一部をなす論述及び図面は、本発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなる。
