Abstract
Description
本実施形態に係る揮発性物質を備えた吸収性物品の一例として、後述する温感剤26を備えたパンツ型吸収性物品1について説明する。なお、以下の説明では生理用の吸収性物品1について説明するが、本実施形態の吸収性物品1には、例えば、大人用、乳児用のおむつ等も含まれており、生理用に用途が限定されるものではない。
次に、吸収性本体20について図3乃至図6を用いて説明する。図3は、吸収性本体20の平面図であり、図4は、図3の矢視A−Aであって、吸収性本体20の断面模式図である。図5、図6については、後述する。
次に、塗布領域26p(温感剤26)の配置について説明する。前述した通り、吸収性本体20における温感剤26の位置により、着用者が感じる温感刺激の強弱や、温感剤26の効果持続時間が異なる。
パンツ型吸収性物品においては、温感剤26と着用者の肌との距離が、着用者が温感を心地よく感じるための1つの要素となる。そして、従来のパンツ型吸収性物品においては、吸収性本体の温感剤26が塗布された領域に胴回り部材10の伸縮による縦縞が形成され、温感剤26と着用者の肌までの距離に遠近が生じて、温感効果が十分に発揮されない問題があった。
上記の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更・改良され得ると共に、本発明には、その等価物が含まれることは言うまでもない。
