Abstract
【解決手段】使い捨ておむつ1は、一対のレッグ開口部よりも製品幅方向内側に、製品長手方向に伸縮するレッグ伸縮部75が配置される。後側レッグ開口部と、製品幅方向における中心を通り製品長手方向に平行な直線との間の面積は、前側レッグ開口部と、レッグ開口部の製品長手方向中心を通り製品長手方向に延びる直線との間の面積よりも広い。レッグ伸縮部よりも製品幅方向外側には、股下域と前記後胴回り域とに跨って配置され、かつ製品長手方向に伸縮する臀部伸縮部が配置され、臀部伸縮部の前端部は、レッグ開口部の前記製品長手方向の中心よりも後方に位置する。
【選択図】図1
Description
図1は、本実施形態に係る使い捨ておむつ10の展開平面図である。図2は、図1に示したF1-F1線に沿った使い捨ておむつの断面図である。図3は、図1に示したF2-F2線に沿った使い捨ておむつの断面図である。図1に示す展開平面図は、使い捨ておむつを構成するトップシート50、サイドフラップ70等の皺が形成されない状態まで、レッグ伸縮部75及びレッグサイドギャザー80の弾性部材81を伸長させた状態の図である。
レッグ伸縮部75は、吸収体40よりも製品幅方向外側において製品長手方向Lに沿って配置され、製品長手方向Lに伸縮可能に構成されている。
なお、本明細書において、かかる伸長率は、例えば、次のように測定されるものとする。
次に、クロッチ伸縮部200の形状について説明する。クロッチ伸縮部200は、吸収体40の他の部分よりも、使い捨ておむつの着用時において股下域の一部に平坦な形状を維持できるように構成されている。クロッチ伸縮部200は、少なくとも製品長手方向Lまたは製品幅方向Wに伸縮可能に構成されている。
なお、伸長率の測定は、上述のレッグ伸縮部と同様であり、説明を省略する。
次に、本実施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。なお、本実施形態において説明しない方法については、既存の方法を用いることができる。また、以下に説明する製造方法は、一例であり、他の製造方法によって製造することもできる。吸収性物品の製造方法は、構成部品形成工程と、構成部品載置工程と、脚回り形成工程と、切断工程とを少なくとも含む。
上述したように、本発明の実施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形態、実施例及び運用技術が明らかとなる。
