Abstract
【解決手段】 使い捨ておむつ1の吸収体130の裏面シート120側の表面には、表面シート110側に向けて凹んだ裏面側凹部135が形成される。裏面側凹部135は、吸収体130の長手方向に連続した溝135a,135bを有する。裏面側凹部135は、使い捨ておむつ1の使用前の状態において裏面シート120の外側から視認可能であるとともに、裏面側凹部135の深さDは、吸収体が液体を吸収することによって、吸収体130が液体を吸収する前よりも浅くなるように構成される。吸収体130が液体を吸収すると、親水性繊維、及び粒子状の高分子吸収体が膨張することによって、吸収体130は、少なくとも厚さ方向に膨らむため、外部からは裏面側凹部135が消失して見える。
【選択図】 図2
Description
本発明の実施形態に係る使い捨ておむつ1の構成について、図面を参照しながら説明する。図1は、使い捨ておむつ1の着用者の肌当接面側からみた斜視図である。
次に、使い捨ておむつ1の吸収体130に裏面側凹部135を形成する方法について説明する。図8は、使い捨ておむつ1を製造する装置の一部を説明する模式図である。装置200は、第1ロール210と、第2ロール220とを有する。
図10は、本発明の他の実施形態に係る使い捨ておむつ2を着用者の肌に当接する表面側からみた斜視図である。以下の説明において、図1に示した使い捨ておむつ1と同様の作用を有する構成については、同一の番号を付して詳細な説明を省略する。
使い捨ておむつ1では、裏面側凹部135は、裏面側からの平面視において、菱形形状であると説明したが、裏面側凹部の形状は、菱形に限定されない。図12は、本発明の他の実施形態に係る使い捨ておむつ3を着用者の肌当接面側の反対側からみた平面図である。使い捨ておむつ3では、吸収体130Bの裏面シート120側の表面に裏面側凹部135’が形成されている。裏面側凹部135’は、ハニカム形状になっている。裏面側凹部135’に囲まれた窓部分136’は、裏面シート120側に突出している。
吸収体の裏面シート側の表面の所定領域に形成された裏面側凹部が裏面シートの外側から視認可能になるか否かは、裏面シートが裏面側凹部の形状に馴染むか否かによって決まると言える。そこで、本発明の発明者らは、使い捨ておむつに適した裏面シートとして使用可能な資材を選択するための指標を見出した。
剛軟度を求める資材の試験片(25mm×150mm)を用意し、5mm/secの速さで試験面上を滑らせて移動距離を測定した。試験片の長手方向と幅方向とで5回ずつ行い、方向毎の平均を求めた。更に、長手方向の平均値と幅方向の平均値の平均を求めた。この値を資材の剛軟度とした。結果を表1に示す。
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の形態、実施例及び運用技術が明らかとなろう。
