Abstract
【解決手段】本発明の生理用ナプキン1は、肌当接面側に液透過性の表面シート2、非肌当接面側に液難透過性の裏面シート3及びこれら両シート間に配された吸収体4を具備する縦長の吸収性物品である。本発明の生理用ナプキン1は、表面シート2の肌当接面に、肌当接面側に盛り上がり且つ生理用ナプキン1の幅方向に延びる液流れ防止壁6、及び表面シート2と吸収体4とを固着し長手方向の両側部に沿って延びる一対の防漏溝7とを備えている。本発明の生理用ナプキン1は、液流れ防止壁6が、長手方向後方領域1aに位置し且つ一対の前記防漏溝7間に亘って設けられている。
【選択図】図1
Description
しかしながら、引用文献1に記載の生理用ナプキンでは、着用中に、着用者の肌と生理用ナプキンとの間に空間ができた場合、着用者の肌を伝わって漏れる伝い漏れを防止することが困難であった。このような伝い漏れは、例えば、就寝中の寝返りにより着用者の肌と生理用ナプキンとの間に空間ができ、着用者の肌を伝わって生理用ナプキンの背側から漏れるという場合がある。
しかしながら、熱エンボスロールにより表面シートを凹凸形状に賦形するには限界があり、伝い漏れを十分に防止することが困難であった。
尚、引用文献2に記載の生理用ナプキンに凹凸形状の表面シートを使用する目的は、表面シートと着用者の肌と張り付き難く、不快感を解消するためであり、伝い漏れについては、何ら記載されていない。
図3に示すように、第1液流れ防止壁6aは、肌当接面側の上層シート2aで形成されており、図2,3に示すように、上層シート2aには、生理用ナプキン1の幅方向における一対の防漏溝7において、非肌当接面側に窪んだ凹部2a’が形成されている。一対の防漏溝7と接する部分の凹部2a’それぞれには、防漏溝7内側まで延在し、防漏溝7に入り込んだ第1入り込み部8aを形成している。この凹部2a’の深さ方向における底部表面2a’’は、吸収体4の平坦部表面4aよりも、深さ方向において非肌当接面側に窪んでいる。
本実施形態の生理用ナプキン1の防漏溝7は、使用時に表面シート2及び吸収体4の皺・ヨレの発生を抑え、着用者へのフィット性及び体液の吸収性を高めるために設けるものであり、図4に示す防漏溝7の断面図は、液流れ防止壁6と接触していない部分を示している。
本実施形態の生理用ナプキン1の第1液流れ防止壁6aの長さL1は、両端に第1入り込み部8aがそれぞれ形成されているため、一対の防漏溝7の間隔W3より若干長く、21〜64mmである。
本実施形態の生理用ナプキン1は、図1に示すように、生理用ナプキン1の長手方向後方領域1aに、5本の液流れ防止壁6が設けられている。これらの5本の液流れ防止壁6それぞれは、肌当接面側に盛り上がっているので、着用者の肌に接しており、着用中に、着用者の肌と生理用ナプキンとの間に空間を生じず、伝い漏れを十分に防止することができる。また、肌当接面側に盛り上がった5本の液流れ防止壁6それぞれは、生理用ナプキン1の幅方向に平行に、一対の防漏溝7間に亘って延びているので、肌を伝ってきた体液を、防漏溝7に導き、横漏れを防止することができる。
特に、本実施形態の生理用ナプキン1は、長手方向後方領域1aに5本の液流れ防止壁6が設けられているので、就寝中に寝返りをしても着用者の肌と生理用ナプキンとの間に空間を生じず、着用者の肌を伝わって生理用ナプキンの背側から漏れる伝い漏れを防止することができる。
また、多量の体液が、第1液流れ防止壁6aにより防漏溝7に導かれても、防漏溝7には、第1入り込み部8aと第2入り込み部8bとが対向して設けられているので、一度、体液が防漏溝7に導かれれば、着用者の肌に付着し、再び着用者の肌を伝わり始めるという再伝い流れを防止することができる。
