Description
前記前身頃と後身頃の相対する長手方向両側縁部は、前記脚周り開口部から所定長さの領域が、その他の領域を接合している接合部よりも接合強度が強い複数の接合部によって接合されており、該複数の接合強度が強い接合部に隣接しておむつのサイズを表示する手段が配置されていて、脚周り開口部側の接合強度が強い接合部を引き裂いて着用者の脚周りに適合したサイズの脚周り開口部を形成して使用できることを特徴とするパンツ型使い捨ておむつ。
このように接合強度が強い接合部近傍に伸縮弾性部材の先端部が位置するように配置して脚周り伸縮弾性体による締めつけ機能を付与することにより、脚周り開口部を引き裂いて脚周り開口部を広げた場合にも脚周り開口部のフィット性を良好な状態に維持できることとなり、本発明の効果をより高めることが可能となる。
さらに、脚周り伸縮弾性体9は、複数本の伸縮弾性部材9’,9’…からなり、各伸縮弾性部材9’が股下部4から各接合強度が強い接合部11の近傍で、そのウエスト周り開口部6側の位置に先端部が位置するように配置されている。
図2〜図5において、接合部5、接合部11及び接合部12は、いずれもおむつの幅方向に長い複数の線状の接合パターンにより形成されており、図2では、脚周り開口部7側に一定間隔で形成された各接合強度が強い接合部11の間に複数本の点線状の接合強度が弱い接合部12が形成されており、図3では、脚周り開口部7側に一定間隔で形成された各接合強度が強い接合部11の間に1本の細線状の接合パターンからなる接合強度が弱い接合部12が形成されている。
あるいは、液透過性のトップシートと、液不透過性のバックシートと、これら両シートの間に配置された吸収体とからなる吸収性本体と、吸収性本体が接合され、これを着用者に当てて保持する外装部材とからなるいわゆるツーピース型のおむつを用い、これを吸収性本体を内側にして折り畳み、外装部材の前後身頃の両側縁部を接合してパンツ型使い捨ておむつを形成することもできる。
