Abstract
Description
本発明の他の特徴については、本明細書及び添付図面の記載により明らかにする。
互いに交差する上下方向と左右方向と前後方向を有し、前側胴回り部と、後側胴回り部と、を有し、前記前側胴回り部又は前記後側胴回り部の少なくとも一方は、前記左右方向に伸縮する弾性部材と、前記前後方向に貫通した孔部を備えた吸収性物品であって、前記前側胴回り部及び前記後側胴回り部のうち、前記左右方向の収縮力が小さい方の一方側胴回り部よりも、前記左右方向の収縮力が大きい方の他方側胴回り部の方が前記孔部を多く備えていることを特徴とする吸収性物品である。
<<<使い捨ておむつ1の構成について>>>
図1Aは、本実施形態の吸収性物品の一例としての自然状態のおむつ1を前側から見た概略正面図である。図1Bは、自然状態のおむつ1を後側から見た概略背面図である。図2は、展開した伸長状態のおむつ1を肌側から見た平面図である。図3は、図2中のIII−III断面図である。図4は、図2中のIV−IV断面図である。
以下、孔部50について説明する。前側胴回り部20及び後側胴回り部30に設けられた複数の孔部50は、それぞれ肌側シート21、31及び非肌側シート22、32を貫通しており、おむつ1の着用時において、肌側から非肌側への通気性を向上させる。前側胴回り部20及び後側胴回り部30の孔部50は、それぞれ略円形状で、略同じ大きさである。図2に示すように、前側胴回り部20には、左右において吸収性本体10より外側、且つ、上下方向において吸収体11と重なる領域11fで、上下方向に隣接する弾性部材25の間に、複数の孔部50がそれぞれ千鳥状に配置されている。後側胴回り部30には、左右方向において吸収性本体10より外側、且つ、上下方向において吸収体11と重なる領域11dで、上下方向に隣接する弾性部材35の間に複数の孔部50がそれぞれ千鳥状に配置されている。このとき、各孔部50は、弾性部材25、35を切断せず、弾性部材25、35は、孔部50によって非連続とはされていないことが好ましい。おむつ1において、領域11fと領域11dの上下方向の長さは、略同じである。
また、「収縮力が大きい方の胴回り部」は、「伸長状態の左右方向の長さと自然状態の左右方向の長さの差」を、「伸長状態の左右方向の長さ」で除した値が小さい方の胴回り部であると言うこともできる。
以上、本発明の実施形態について説明したが、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。また、本発明は、その趣旨を逸脱することなく、変更や改良され得るとともに、本発明にはその等価物が含まれるのはいうまでもない。例えば、以下に示すような変形が可能である。
