Abstract
Description
しかし、オムツの幅方向の中央を横切る前記弾性部材を少なくとも製造段階でウエブに配置する必要があるので、当該部分の弾性部材が無駄になる。
ここで、着用者の体液が吸収性本体に吸収されると、該体液の重みによりオムツがズリ下がるおそれがある。しかし、特許文献2のオムツでは、前記弾性部材が、横漏れを防止するための脚周り弾性部材としてのみ機能するので、オムツのズリ下がりを防止し得ない。
い第1領域と、前記第2分割シートにおける前記第2頂部と第2頂部との間の引上用弾性部材が配置されていない第2領域とに跨がるように前記コア部を配置して積層体を得る工程とを備えている。
また、前記引上用弾性部材を所定の波形に沿って配置し、第1頂部を有する第1分割シートと、第2頂部を有する第2分割シートの流れ方向の位相を互いにずらすことにより、引上用弾性部材が配置されていない領域にコア部が配置される。したがって、弾性部材に無駄が生じにくい。
この例の場合、引上用弾性部材が腰下部弾性部材FBを斜めに横断するから、オムツやパンツのズリ下がりを防止できる。
すなわち、引上用弾性部材が腰下部弾性部材よりもきつい傾斜角度で斜め上方向の力を各胴部に与えることで、各胴部を吊り上げるようにして着用者の胴にオムツやパンツを密着保持することが可能になる。
前記第1および第2分割シートを前記幅方向に沿って切断して前記積層体から個々の着用物品となる部位を切り取る工程とを更に備え、前記コア部は前記幅方向に延びるレッグ用弾性部材を備え、前記積層体を得る工程において、前記引上用弾性部材の前記切断された端部が前記コア部の前記レッグ用弾性部材に連なるように前記コア部を配置し、これにより前記着用物品の前記引上用弾性部材と前記レッグ用弾性部材とでループ状の弾性領域が形成されている。
この例の場合、前記ループ状の弾性領域が形成されることにより、着用物品のずり下がり防止の機能が高まると共に、体液の漏れを確実に防止することができる。
図1、図2Aおよび図2Bには、本製造方法によって製造された着用物品の一例が示される。
図1に示すように、本実施例1の着用物品は、パンツ型に形成されており、着用者の胴部の一部を覆う第1胴部S1、着用者の他の胴部を覆う第2胴部S2および着用者の股を覆うコア部Cを備えている。
前記第1および第2胴部S1,S2には、その長手方向Lに沿った複数本のウエスト弾性部材FWおよび複数本の腰下部弾性部材FBが所定の間隔で配置されている。前記腰下部弾性部材FBが配置された領域には、多数本の腰下部弾性部材FBのうち概ね大半の腰下部弾性部材FBを前記各引上用弾性部材FUが第1および第2胴部S1,S2の幅方向Dに斜めに横断するように配置されている。
したがって、前記着用物品を図1に示すように第1および第2胴部S1,S2の端部S1e,S2e同士を互いに溶着してパンツ型に形成すると、引上用弾性部材FUとレッグ用弾性部材FLとでループ状の弾性領域FAが形成される。
以下、前記着用物品の製造方法の一例が説明される。
複合シートWsの生成工程;
図3Aに示すように、搬送方向Xに搬送される2枚の帯状のウエブWの間に、各々、複数本のウエスト弾性部材FW、腰下部弾性部材FBおよび引上用弾性部材FUが挟まれて複合シートWsが形成される。
前記複合シートWsを生成する工程において、引上用弾性部材FUは、概ね全ての腰下部弾性部材FBを幅方向Dに斜めに横断するようにウエブWに配置される。
前記引上用弾性部材FUは、所定の波長λを持つ波形に沿って搬送中のウエブWに配置される。前記波形の複数の第1頂部α1は前記第1側縁部W1sの近傍に配置され、かつ、前記第1頂部α1の隣の複数の第2頂部α2は第2側縁部W2sの近傍に配置されている。
搬送中の複合シートWsは、引上用弾性部材FUと共に、前記複合シートWsの長手方向Lに連続する切断線CLに沿って切断される。前記切断により、複合シートWsは第1および第2分割シートW1,W2に分割される。
前記分割後、図5に示すように、前記第1側縁部W1sから第2側縁部W2sまでの距離幅d1が広がるように、2つの分割シートW1,W2が幅方向Dに相対移動(拡幅)される。
ついで、第1分割シートW1の第1頂部α1と、第2分割シートW2の第2頂部α2とが互いに対向するように、第1分割シートW1と第2分割シートW2の流れ方向Xの位相が互いにずらされる。すなわち、図4および図5に示すように、一方の分割シートW1(W2)の流れ方向Xの位相が他方の分割シートW2(W1)に対して半波長λ/2ずらされる。
これにより、図5に示すように、第1分割シートW1の第1頂部α1と、第2分割シートW2の第2頂部α2とが概ね線対称に配置された状態となる。
前記位相をずらす工程の後に、前記第1および第2領域E1,E2において、腰下部弾性部材FBが切断されて、該腰下部弾性部材FBの張力を失わせる。その後、前記第1および第2領域E1,E2にコア部Cが配置される。
また、前述の説明では、着用物品の一例としてパンツ型のオムツを例示したが、前記着用物品としては、前記パンツ型のオムツの他に、たとえば、着用時にウエスト部分の前部と後部とを止めるタイプのオムツであってもよい。
