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。
前後方向と幅方向と厚さ方向とを有し、液体を吸収する吸収体、及び非肌側面に粘着部を有する吸収性物品であって、前記吸収体は、高剛性領域と、前記高剛性領域より剛性が低い低剛性領域を備え、前記粘着部は、第1粘着領域と第2粘着領域を有し、前記第1粘着領域は、前記前後方向における中央より前側に、第11粘着部を備え、前記第2粘着領域は、前記前後方向における中央より前側で、且つ、前記幅方向における中央より一方側に第21粘着部を備え、前記厚さ方向に前記吸収性物品を平面視したとき、前記第11粘着部は、前記高剛性領域と重なる部分を有し、前記第21粘着部は、前記低剛性領域と重なる部分を有し、前記高剛性領域と重なる部分に、前記粘着部が設けられていない非粘着部が設けられており、前記非粘着部は、前記第11粘着部と前記高剛性領域とが重なる部分に前記幅方向の両側から挟まれており、前記幅方向の一方側において、前記第21粘着部の前記幅方向の前記一方側における側端は、前記第11粘着部のうちの前記高剛性領域と重なる部分の、前記幅方向の前記一方側における側端よりも外側に設けられていることを特徴とする吸収性物品である。
以下、本実施形態に係る吸収性物品の一例として、軽失禁パッドを例に挙げて説明する。ただし、吸収性物品は軽失禁パッドに限定されず、他の吸収性物品として、例えば、生理用ナプキンやパンティライナ等の着用者の着衣に固定して着用する吸収性物品が挙げられる。
図1は、伸長状態である軽失禁パッド1(以下、「パッド1」ともいう。)を肌側から見た平面図である。図2は、伸長状態であるパッド1を非肌側から見た平面図である。図3は、図1のC-Cにおけるパッド1のA-A矢視概略断面図である。なお、パッド1の伸長状態とは、パッド1を皺なく伸長させた状態である。具体的には、パッド1を構成する各資材の寸法が、パッド1が有する弾性部材の影響を受けない状態で、その資材単体の寸法と一致又はそれに近い長さになるまで、パッド1を伸長させた状態である。
図4は、着用状態のパッド1を説明する模式図である。図4Aは、着用状態で、且つ、パッド1の幅方向の外側から内側に向かって力が加えられていない状態を示しており、図4Bは、着用状態で、且つ、パッド1の幅方向の外側から内側に向かって力が加えられた状態を示している。図4A及び図4Bは、着用時におけるパッド1の前後方向における中央C-Cにおける断面を模式的に示した図である。
が設けられている。この非粘着部31は、第11粘着部11と高剛性領域Hとが重なる部分に、幅方向の両側から挟まれている。
本実施形態では、図5等に示すように、パッド1の前後方向における中央C-Cより前側において、非粘着部31は、幅方向において、一方側第11粘着部11aと他方側第11粘着部11bとの間に設けられており、一方側第11粘着部11aと高剛性領域Hとが重なる部分と、他方側第11粘着部11bと高剛性領域Hとが重なる部分に、幅方向の両側から挟まれている。
パッド1において、幅方向における一方側だけでなく他方側についても、パッド1への着衣への追従性を向上させつつ、サイド粘着領域20同士が幅方向に接着する恐れを軽減させることができる。さらに、第23粘着部23の幅方向の長さより前後方向の長さが長いことが好ましく、第24粘着部24の幅方向の長さより前後方向の長さが長いことが好ましい。パッド1における後側においても、着衣への追従性を向上させつつ、サイド粘着領域20同士の接着を軽減させやすくなる。
パッド1は、個別に包装された包装状態(不図示)で流通され、着用者に提供されるとよい。パッド1の包装体100としては、図7に示すように包装材101の上に、剥離シート102を介してパッド1が載置されて、パッド1が幅方向に沿う2つの折り線部F1、F2にて包装材101とともに折り畳まれて、止着テープ103で固定されるものを例示できる。図7は、展開状態の包装体100を説明する図である。
パッド1に第1折り線部F1による折り癖が形成され、着用状態でパッド1の変形が生じた場合でも、着用状態では、第1折り線部F1より前側に位置する第21粘着部21を着衣に固定した状態を維持しやすくなるため、着衣の復元力に伴って、パッド1の変形を元に戻しやすくなり、着用者の違和感を軽減させやすくなる。
高剛性領域Hと低剛性領域Lとの境界は、剛性差によって変形しやすい部分である。そのため、高剛性領域Hと低剛性領域Lとの境界と、剥離シート102とを重ねることで、包装状態及び展開状態の包装体100の高剛性領域Hと低剛性領域Lとの境界における変形を軽減させやすくなる。本実施形態の包装体100は、図7に示すように、平面視において、低剛性領域Lが高剛性領域Hより大きく、高剛性領域Hの全域が低剛性領域Lと重なることから、高剛性領域Hの外端が高剛性領域Hと低剛性領域Lとの境界となる。そして、包装体100を平面視したとき、高剛性領域Hの前端における幅方向の中央部が剥離シート102と重なり、高剛性領域Hの後端における幅方向の中央部が剥離シート102と重なる。そのため、包装状態及び展開状態の包装体100の前側の高剛性領域Hと低剛性領域Lとの境界に生じる幅方向に沿う変形、包装体100の後側の高剛性領域Hと低剛性領域Lとの境界に生じる幅方向に沿う変形が生じる恐れを軽減させることができる。
図8は、第1実施形態の変形例のパッド1Aを非肌側から見た平面図であり、図9は、図9は、第1実施形態の変形例のパッド1Bを非肌側から見た平面図である。以下、軽失禁パッド1A、1B(以下、「パッド1A」、「パッド1B」ともいう。)について、主に第1実施形態と異なる部分を、図8及び図9を参照して説明し、第1実施形態の構成と共通する部分は、符号等を同じとし、基本構成の詳細な説明は省略する。
上述のパッド1は、幅方向の中央部に非粘着部31を有し、非粘着部31の両側に一対の第11粘着部11(一方側第11粘着部11a、他方側第11粘着部11b)を備えた中央粘着領域10を有していたが、これに限られない。図8に示すように、パッド1Aが、1つの中央粘着領域(第1粘着領域)10が、1つの第11粘着部11を備え、第11粘着部11(中央粘着領域10)の内側に、粘着部3が設けられていない非粘着部31を配置する構成であってもよい。
上述のパッド1は、それぞれ分離した状態の中央粘着領域10とサイド粘着領域20とを有したが、これに限られない。中央粘着領域(第1粘着領域)10とサイド粘着領域(第2粘着領域)20が一体の粘着部3として配置されていてもよい。例えば、図9に示すように、パッド1Bが、幅方向の両側に、一対の矩形状の粘着領域からなる粘着部3を備えてもよい。
例えば、吸収性コアが、液体吸収性繊維を備え、吸収性コアのうち、幅方向における中央部で、且つ、前後方向における中央部を高剛性領域Hとし、幅方向における中央部より外側で、且つ、前後方向における中央部より外側を低剛性領域Lとした場合、低剛性領域Lにおける液体吸収性繊維の坪量を、高剛性領域Hにおける液体吸収性繊維の坪量より少なくすることで、低剛性領域Lの剛性を高剛性領域Hの剛性より低くしてもよい。
吸収体が、厚さ方向に3つ以上の吸収体が重ねられた多層吸収体であってもよい。例えば、パッドが、第1吸収体と第2吸収体と、厚さ方向にさらに重ねた第3吸収体を備えている場合、厚さ方向にパッドを平面視したとき、2つ以上の吸収性コアが重なる領域を高剛性領域Hといい、吸収性コア同士の重なりが存在しない領域を低剛性領域Lという。
高剛性領域Hより幅方向の外側に第21粘着部21を設けることで、第21粘着部21と着衣との追従性を向上させやすくなる。
