Abstract
【解決手段】ナプキン1の幅方向中央部であって、少なくとも排血部Hから臀裂部Sにかけた範囲に使用面側に隆起した中高部吸収体6を有するとともに、この中高部吸収体6の両側にほぼナプキン1の長手方向に延びる左右一対の圧搾溝8c〜8fを備え、該圧搾溝8e〜8fは、前記排血部H及び前記臀裂部SKにおける圧搾溝8c、8e間の幅B1、B3よりも、これら排血部Hと臀裂部SKとの間の会陰部における圧搾溝8d間の幅B2が小さくなるように形成されるとともに、前記臀裂部SKから後部側にかけて圧搾溝間の幅B4が漸次縮小するように形成され、かつ少なくとも前記会陰部から臀裂部にかけた範囲Sにおいて前記左右一対の圧搾溝8c〜8f以外の圧搾溝を有しない構造とする。
【選択図】図5
Description
前記吸収性物品の幅方向中央部であって、少なくとも排血部から臀裂部にかけた範囲に使用面側に隆起した中高部吸収体を有するとともに、この中高部吸収体の両側にほぼ吸収性物品の長手方向に延びる左右一対の圧搾溝を備え、該圧搾溝は、前記排血部及び臀裂部における圧搾溝間の幅よりも、これら排血部と臀裂部との間の会陰部における圧搾溝間の幅が小さくなるように形成されるとともに、前記臀裂部から後部側にかけて圧搾溝間の幅が漸次縮小するように形成され、かつ少なくとも前記会陰部から臀裂部にかけた範囲において前記左右一対の圧搾溝以外の圧搾溝を有しないことを特徴とする吸収性物品が提供される。
〔生理用ナプキン1の基本構造〕
図1は本発明に係る生理用ナプキン1の展開図であり、図2は図1のII−II線矢視図、図3は図1のIII−III線矢視図、図4は図1のIV−IV線矢視図である。
前記不透液性バックシート2は、ポリエチレン等の少なくとも遮水性を有するシート材が用いられるが、近年はムレ防止の観点から透湿性を有するものが用いられる傾向にある。この遮水・透湿性シート材としては、ポリエチレンやポリプロピレン等のオレフィン系樹脂中に無機充填剤を溶融混練してシートを成形した後、一軸または二軸方向に延伸することにより得られる微多孔性シートが好適に用いられる。前記不透液性バックシート2の非使用面側(外面)には1または複数条の粘着剤層(図示せず)が形成され、身体への装着時に生理用ナプキン1を下着に固定するようになっている。前記不透液性バックシート2としては、プラスチックフィルムと不織布とを積層させたポリラミ不織布を用いてもよい。
本生理用ナプキン1においては、詳細には図5に示されるように、幅方向中央部に使用面側に隆起した中高部吸収体6を有するとともに、この中高部吸収体6を囲むように、ナプキン1の長手方向に細長い圧搾溝8が形成されている。この圧搾溝8は、前部側から順に、前端部圧搾溝8a、縮小形状圧搾溝8b、排血部圧搾溝8c、会陰部圧搾溝8d、臀裂部圧搾溝8e、臀裂後部側圧搾溝8fから構成されている。これら各圧搾溝は分断することなく連続的に形成され、全体として周方向に閉合している。なお、前記圧搾溝8は、熱及び/又は圧力によるエンボッシングや、超音波、またはその組合せ等、任意の手段によって付与することが可能である。
(1)前記中高部吸収体6の厚みは、全長に亘って等厚とすることでもよいが、臀裂部から後部側にかけて厚みが漸次減少するようにするのが望ましい。臀部の窪みは、肛門部から後側にかけて漸次浅くなっているため、これに合わせて中高部吸収体6の厚みを減少させることにより、臀裂部での違和感を解消することができるとともに、中高部吸収体6の剛性が後部側にかけて漸次小さくなることにより、ナプキン1が臀部に沿って曲線状にフィットし易くなる。
(2)上記形態例では、圧搾溝8は前後部で結合され、周方向に閉合した平面形状としたが、前後部で閉合しない平面形状とすることも可能である。
Claims (5)
- 透液性トップシートとバックシートとの間に吸収体が介在された吸収性物品において、

- 前記中高部吸収体は、前記臀裂部から後部側にかけて厚みが漸次減少するようにしてある請求項1〜4いずれかに記載の吸収性物品。
