Description
前記伸縮性シートの前記中央固定域と前記ウエストシートの前記非固定部とを互いに固定する接合域と、前記ウエスト弾性体のうちの最内側に位置する弾性体とが、平面視において重なり合って位置している。
図2及び図3を参照すると、前ウエストパネル30は、肌対向面側に位置する内面シート31と、非肌対向面側に位置する外面シート32とを有する。外面シート32は、内面シート31と互いに固定される主体部34と、吸収パネル20の前端部20Aから縦方向の外側に位置する折曲部35とを有する。折曲部35は、横方向X延びる折曲ライン35aに沿って縦方向Yの内側に折曲されて吸収パネル20の前端部20Aの内面に固定される。内面シート31と外面シート32の主体部34との間には、複数条のストランド状又はストリング状の前ウエスト弾性体36が、横方向Xに伸長状態で収縮可能に固定される。
後ウエストパネル40は、肌対向面側に位置する内面シート41と、非肌対向面側に位置する外面シート42とを有する。外面シート42は、内面シート41と接合される主体部44と、吸収パネル20の後端部20Bから縦方向Yの外側に位置する折曲部45とをさらに有する。該折曲部45は、横方向X延びる折曲ライン45aに沿って縦方向Yの内側に折曲されて内面シート41の肌対向面側に固定される。内面シート41と外面シート42の主体部44との間には、複数条のストランド状又はストリング状の後ウエスト弾性体46が、横方向Xに伸長状態で収縮可能に固定される。
図2及び図3を参照すると、吸収パネル20は、前ウエスト域13に位置する前端部20Aと、後ウエスト域14に位置する後端部20Bと、前後端部20A,20B間において縦方向Yへ延び、クロッチ域15を画成する中間部20Cとを有する。吸収パネル20は、肌対向面側に位置し、透液性を有する繊維不織布製の身体側ライナー21と、曲状の両側縁を有する吸液性の吸液構造体22と、少なくとも吸液構造体22の底面全体を覆う不透液性の防漏シート23と、吸収パネル20の非肌対向面全体を形成する不透液性の被覆シート24とをさらに有する。吸液構造体22は、フラッフ木材パルプと超吸収性ポリマー粒子等との混合物から形成された吸収性コアと、芯材全体を包被するティッシュペーパ等の液吸収拡散性のコアラップシート(図示せず)とを含む。
吸液構造体22と並行して延びる場合に比して、適度なフィット感を与えることができる。また、ポケット70は、非固定域53と身体側ライナー21との間のスペースとそれよりも縦方向Yの外側へ延びる非固定部71と身体側ライナー21とのスペースとが連通した比較的に大きなスペースから形成され、比較的に多量の排泄物を収容することができる。なお、本実施形態においては、肌側弾性シート50の中央固定域52が、外面シート32の折曲部35の外面に固定されているが、折曲部35が肌側弾性シート50の外面に固定されていてもよい。すなわち、肌側弾性シート50のサイド固定域51を前ウエスト域13の内端部13Aに固定した後に、折曲部35を肌側弾性シート50の上に重ね合わせて固定することによって、ポケット70を形成してもよい。
前ウエスト域13の各領域における伸長応力の測定は、引張試験機(例えば、(株)島津製作所製のオートグラフ引張試験機(AG−1KNI)を用いて、サイクル試験によって行った。
図8は、第2実施形態に係るおむつ10の図4と同様の前ウエスト域13の平面図、図9は、図8に示すIX−IX線に沿う断面図である。本実施形態に係るおむつ10の基本的構成は、第1実施形態に係るおむつ10と同様であるので、相違する点についてのみ、以下に説明する。
