Abstract

PROBLEM TO BE SOLVED: To provide a disposable excretion discarding pad which does not require labor for wearing, and can be closely joined to the skin of a wearer without using underpants. SOLUTION: To this disposable excretion discarding pad 1A, a pair of band pieces 10 and 11 which are arranged laterally in parallel while being separated by a specified dimension are attached in the front region 5. In the pad 1A, a rear surface sheet 3 extends circumferentially inward from the peripheral edge parts 7 and 8 of the front and rear regions 5 and 6. At the same time, a peripheral wall part 9 which surrounds the peripheral edge parts 7 and 8 of the regions 5 and 6, and can elastically stretch/contract circumferentially is formed. The strips 10 and 11 each have a first fixing part 21 and a second fixing part 22, and a gripping part 23 which substantially draws a loop between the fixing parts 21 and 22.

Description

【０００１】
【発明の属する技術分野】
本発明は、排泄物を吸収、保持する使い捨て排泄物処理パッドに関する。
【０００２】
【従来の技術】
肌当接側に位置する透液性表面シートと肌非当接側に位置する不透液性裏面シートとの間に吸液性コアが介在し、横方向へ延びる両端縁部と、縦方向へ延びる両側縁部とを有する縦長矩形の使い捨て排泄物処理パッドは公知である（特許文献１参照）。
【０００３】
特許文献１に開示のパッドは、その着用時に、着用者の腹部の側に位置する前域と、着用者の臀部の側に位置する後域とを有する。このパッドの縦方向中央には、環状の細長いゴムが取り付けられている。ゴムは、その両端部が裏面シートの外面に固着され、両端部の間に延びる中央部が裏面シートの外面から遊離している。このパッドは、パンツの内側にのせてパンツとともに着用する。このパッドは、裏面シートに取り付けられたゴムがパンツの内側に接するので、ゴムが滑り止めとなってパンツに対するパッドのずれを防ぐことができる。

特開２００２−１１９５２８号公報
【０００５】
【発明が解決しようとする課題】
特許文献１に開示のパッドは、その着用時にパッドをパンツにのせるだけなので、パッドそれ自体が着用者の肌に密着することはなく、パンツを介してパッドを着用者の肌に密着させる必要がある。このパッドは、パンツが着用者の胴部からずれ下がると、それにともなってパッドもずれ下がり、パッドが着用者の肌から離間してパッドに排泄物を吸収させることができない。また、このパッドは、パンツとともに着用しなければならないので、特に寝たきりの着用者にパッドを着用させる場合、パンツを着用させた後にパッドをパンツの内側に配置しなければならず、パッドの着用に手間を要する。
【０００６】
本発明の課題は、着用に手間を要せず、パンツを介さずに着用者の肌に密着させることができる使い捨て排泄物処理パッドを提供することにある。
【０００７】
【課題を解決するための手段】
前記課題を解決するための本発明の前提は、肌当接側に位置する透液性表面シートと、肌非当接側に位置する不透液性裏面シートと、それらシートの間に介在する吸液性コアとから構成され、縦方向に並ぶ前域および後域を備えた縦長の使い捨て排泄物処理パッドである。
【０００８】
前記前提における本発明の特徴は、前記表裏面シートのうちの少なくとも該裏面シートが、前記前後域の周縁部から周方向内方へ延びるとともに、それら域の周縁部を囲繞して周方向へ弾性的に伸縮可能な周壁部を形成し、前記パッドが、前記前域に配置されて横方向へ所与寸法離間して並ぶ一対の帯片を備え、それら帯片が、前記周壁部に固着された第１固定部と、前記周縁部に固着された第２固定部と、前記前域の周縁部から縦方向外方へ延びていて前記第１および第２固定部の間で実質的にループを画く把持部とを有することにある。

（４）前記前域における前記パッドの曲げ剛性が、前記後域における前記パッドの曲げ剛性よりも小さく、前記前域における前記パッドの曲げ剛性が、０．０５〜０．２Ｎ／ｇの範囲、前記後域における前記パッドの曲げ剛性が、０．２〜２．０Ｎ／ｇの範囲にある。
（５）前記パッドの平面形状が、前記前後域の間がくびれた実質的に縦長円形を呈し、前記前域の面積が、前記後域の面積よりも小さい。
（６）前記前域と前記後域との間には、それら域を互いに重ね合わせるように前記パッドを２つに折り畳むための横方向へ延びる折曲部が形成され、前記折曲部における前記パッドの曲げ剛性が、前記前後域における前記パッドの曲げ剛性よりも小さい。
（７）前記前域と前記後域との間には、それら域を互いに重ね合わせるように前記パッドを２つに折り畳むための横方向へ延びる折曲部が形成され、前記折曲部が、前記コアを除く前記表面シートと前記裏面シートとから形成されている。
（８）前記前域と前記後域とのいずれか一方には、縦方向へ延びる止着テープが取り付けられ、前記止着テープが、前記域の周縁部に固着された基端部と、前記域の周縁部から縦方向外方へ延びる粘着性の自由端部とを有する。
【００１０】
【発明の実施の形態】
添付の図面を参照し、本発明に係る使い捨て排泄物処理パッドの詳細を説明すると、以下のとおりである。
【００１１】
図１，２は、一例として示す排泄物処理パッド１Ａの斜視図と、図１のＩＩ−ＩＩ線矢視断面図とであり、図３は、図１のＩＩＩ−ＩＩＩ線矢視断面図である。図１では、横方向を矢印Ｌ、縦方向を矢印Ｍで示し、厚み方向を矢印Ｎで示す。なお、表裏面シート２，３の内面とは、コア４に対向する面をいい、それらシート２，３の外面とは、コア４に非対向の面をいう。
【００１２】
パッド１Ａは、肌当接側に位置する透液性表面シート２と、肌非当接側に位置する不透液性裏面シート３と、表裏面シート２，３の間に介在する吸液性コア４とから構成されている。パッド１Ａは、縦方向に並ぶ前域５および後域６を備え、それら域５，６を周方向へ延びる周縁部７，８と、それら域５，６の周縁部７，８の上方に位置して周方向へ延びる弾性的に伸縮可能な周壁部９とを有する。周縁部７，８は、表裏面シート２，３とコア４とから形成されている。
【００１３】
パッド１Ａは、前後域５，６の周縁部７，８が弧を画くとともにそれら域５，６の間が横方向内方へくびれており、その平面形状が実質的に縦長円形（瓢箪型）を呈する。パッド１Ａでは、前域５の面積が後域６のそれよりも小さい。パッド１Ａには、それを縦方向へ引っ張ることが可能な一対の第１および第２帯片１０，１１と、パッド１Ａの折り畳まれた状態（図５参照）を維持するための止着テープ１２とが取り付けられている。
【００１４】
表面シート２は、親水性繊維不織布１３から形成されている。裏面シート３は、互いに重なり合う通気不透液性プラスチックフィルム１４と疎水性繊維不織布１５とをラミネートした複合シートから形成されている。裏面シート３では、フィルム１４がコア４の側に位置し、不織布１５がフィルム１４の外側に位置している。フィルム１４と不織布１５とは、それらの対向面が接着剤（図示せず）を介して断続的に固着されている。
【００１５】
コア４は、前域５と後域６とに位置し、その上下面が表裏面シート２，３の内面に接着剤（図示せず）を介して断続的に固着されている。コア４は、フラッフパルプと高吸収性ポリマー粒子との混合物、または、フラッフパルプと高吸収性ポリマー粒子と熱可塑性合成樹脂繊維との混合物であり、所定の厚みに圧縮されている。ゆえに、コア４は、その剛性が表面シート２や裏面シート３のそれよりも大きい。コア４は、その型崩れやポリマー粒子の脱落を防ぐため、全体がティッシュペーパーや親水性繊維不織布等の透液性シートで包被されていることが好ましい。
【００１６】
周壁部９は、前後域５，６の周縁部７，８全周を囲繞している。周壁部９は、その大部分が前後域５，６の周縁部７，８から周方向内方へ延びる裏面シート３から形成されている。周壁部９では、コア４の周縁４ａから外側へ表面シート２がわずかに延び、表面シート２からさらに外側へ裏面シート３が延びている。表面シート２と裏面シート３との互いに重なり合う部分では、それらシート２，３の内面どうしが接着剤（図示せず）を介して断続的に固着されている。
【００１７】
周壁部９には、その周方向へ実質的に環状を画く複数条の伸縮性弾性部材１６が収縮可能に取り付けられている。それら弾性部材１６は、周壁部９の周方向外方から周方向内方へ向かって所与寸法離間して並び、所定の倍率に伸長させた状態で周壁部９に取り付けられている。弾性部材１６は、裏面シート３を形成するフィルム１４と不織布１５との間に介在し、それらの対向面に接着剤（図示せず）を介して固着されている。周壁部９は、前後域５，６の周縁部７，８上面を覆うように、弾性部材１６の収縮力によって周縁部７，８の上方で周方向へ収縮かつ周方向内方へ狭窄している。周縁部７，８と周壁部９との間には、周方向内方へ向かって開口するポケット１７が形成されている。
【００１８】
前域５では、そこに位置するコア４の厚み寸法が後域６に位置するコア４の厚み寸法よりも大きく、コア４の肌当接側から上方への隆起高さが後域６に位置するコア４の肌当接側から上方への隆起高さよりも大きい。パッド１Ａでは、前域５と後域６とにパッド１Ａの厚み方向へ段差が形成されている。前域５におけるコア４の隆起高さ（厚み寸法）を後域６におけるコア４のそれよりも大きくするには、コア４を形成するパルプや合成樹脂繊維の分量を後域６よりも前域５で多くしたり、前後域５，６でパルプや合成樹脂繊維の分量が同一であれば、後域６のコア４を厚み方向へ圧縮すればよい。
【００１９】
後域６では、その周縁部８に位置するコア４の厚み寸法が周縁部８を除く後域６の残余部１８に位置するコア４の厚み寸法よりも大きく、周縁部８に位置するコア４の肌当接側から上方への隆起高さが残余部１８に位置するコア４の肌当接側から上方への隆起高さよりも大きい。パッド１Ａでは、後域６の周縁部８と残余部１８とにパッド１Ａの厚み方向へ段差が形成されている。後域６の周縁部８におけるコア４の隆起高さ（厚み寸法）を残余部１８におけるコア４のそれよりも大きくするには、コア４を形成するパルプや合成樹脂繊維の分量を残余部１８よりも周縁部８で多くしたり、周縁部８と残余部１８とでパルプや合成樹脂繊維の分量が同一であれば、残余部１８のコア４を厚み方向へ圧縮すればよい。なお、後域６の周縁部８に位置するコア４の厚み寸法は、前域５に位置するコア４の厚み寸法よりも小さく、後域６の周縁部８に位置するコア４の肌当接側から上方への隆起高さは、前域５に位置するコア４の肌当接側から上方への隆起高さよりも小さい。
【００２０】
前域５と後域６との間には、それら域５，６を互いに重ね合わせるようにパッド１Ａを縦方向へ２つに折り畳むための横方向へ延びる折曲部１９が形成されている。折曲部１９では、そこに位置するコア４の厚み寸法が前後域５，６に位置するコア４の厚み寸法よりも小さく、折曲部１９おけるパッド１Ａの曲げ剛性が前後域５，６におけるパッド１Ａの曲げ剛性よりも小さい。折曲部１９におけるコア４の厚み寸法を前後域５，６におけるコア４のそれよりも小さくするには、コア４を形成するパルプや合成樹脂繊維の分量を前後域５，６よりも折曲部１９で少なくすればよい。折曲部１９におけるパッド１Ａの曲げ剛性を前後域５，６におけるパッド１Ａのそれよりも小さくするには、コア４を形成するパルプや合成樹脂繊維の密度を前後域５，６よりも折曲部１９で低くすればよい。
【００２１】
パッド１Ａは、前域５における曲げ剛性が後域６における曲げ剛性よりも小さい。パッド１Ａの前域５における曲げ剛性を後域６における曲げ剛性よりも小さくするには、コア４を形成するパルプや合成樹脂繊維の密度を後域６よりも前域５で低くすればよい。パッド１Ａは、前域５の曲げ剛性が０．０５〜０．２Ｎ／ｇの範囲にあり、後域６の曲げ剛性が０．２〜２．０Ｎ／ｇの範囲にある。
【００２２】
前域５におけるパッド１Ａの曲げ剛性が０．０５Ｎ／ｇ未満では、帯片１０，１１を介してパッド１Ａを縦方向外方へ引っ張ったときに（図４参照）、パッド１Ａの前域５に不規則な多数の折れ曲がり部分が形成される場合がある。折れ曲がり部分では、表面シート２の外面どうしが互いに当接し、尿がコア４に滲入し難くなるので、前域５におけるパッド１Ａの排泄物吸収機能を十分に利用することができなくなる。前域５におけるパッド１Ａの曲げ剛性が０．２Ｎ／ｇを超過すると、パッド１Ａの柔軟性が低下し、前域５を着用者の肌にあてがったときに、着用者に不快な感触を与える場合がある。
【００２３】
後域６におけるパッド１Ａの曲げ剛性が０．２Ｎ／ｇ未満では、パッド１Ａが後域６において折れ曲がり易く、着用者がパッド１Ａを着用したときに（図４参照）、後域６が部分的に折れ曲がった状態で着用者の臀部の下に敷かれてしまう場合がある。後域６におけるパッド１Ａの曲げ剛性が２．０Ｎ／ｇを超過すると、後域６が着用者の臀部の形状に沿って変形し難く、臀部の荷重が後域６の一箇所に集中し、臀部の荷重を後域６全体に分散させることができない場合がある。なお、それら曲げ剛性は、以下の方法で測定した。
（１）曲げ剛性測定器と水平板とを使用して曲げ剛性を測定した。なお、曲げ剛性測定器には、社名ＮＩＤＥＣ−ＳＨＩＭＰＯｃｏｒｐｏｒｅｔｉｏｎ製の機械名ＤＩＧＴＡＬＦＯＲＣＥＧＡＵＧＥを使用した。
（２）最初に、前域５の曲げ剛性の測定方法を説明する。裏面シート３が水平板に当接するように、パッド１Ａを水平板の上に乗せ、パッド１Ａの前域５の前半分を水平板の端縁から外側に露出させた状態でパッド１Ａを水平板に固定する。
【００２４】
前域５の前半分の上に測定器のアームを当接させ、測定器を水平板の下方へ徐々に下げて行く。測定器を水平板の下方へ下げて行くと、測定器のアームによって前域５の前半分が水平板の下方へ押し下げられ、前半分が水平板の下方へ次第に折れ曲がる。前域５におけるパッド１Ａの曲げ剛性は、水平板の下方へ折れ曲がった前域５の前半分が水平板に対して４５度の角度をなしたときの測定器が示す数値を用いた。
（３）次に、後域６の曲げ剛性の測定方法を説明する。裏面シート３が水平板に当接するように、パッド１Ａを水平板の上に乗せ、パッド１Ａの後域６の後半分を水平板の端縁から外側に露出させた状態でパッド１Ａを水平板に固定する。
【００２５】
後域６の後半分の上に測定器のアームを当接させ、測定器を水平板の下方へ徐々に下げて行く。測定器を水平板の下方へ下げて行くと、測定器のアームによって後域６の後半分が水平板の下方へ押し下げられ、後半分が水平板の下方へ次第に折れ曲がる。後域６におけるパッド１Ａの曲げ剛性は、水平板の下方へ折れ曲がった後域６の後半分が水平板に対して４５度の角度をなしたときの測定器が示す数値を用いた。
【００２６】
第１および第２帯片１０，１１は、前域５に配置されて横方向へ所与寸法離間して並んでいる。帯片１０，１１は、非伸縮性の繊維不織布２０から形成されている。それら帯片１０，１１は、前域５の周縁部７を囲繞する周壁部９に固着された第１固定部２１と、前域５の周縁部７に固着された第２固定部２２と、前域５の周縁部７から縦方向外方へ延びる把持部２３とを有する。第１および第２固定部２１，２２では、帯片１０，１１を形成する不織布２０が裏面シート３を形成するフィルム１４と不織布１５とに接着剤（図示せず）を介して固着されている、把持部２３は、第１および第２固定部２１，２２の間で実質的にループを画いている。
【００２７】
止着テープ１２は、可撓性を有するプラスチックフィルムから形成され、前域５の周縁部７に取り付けられて縦方向へ延びている。テープ１２は、前域５の周縁部７における裏面シート３の外面に固着された基端部２４と、前域５の周縁部７から縦方向外方へ延びる自由端部２５とを有する。基端部２４は、裏面シート３の外面に接着剤（図示せず）を介して固着されている。自由端部２５は、断面Ｚ字状に折り畳まれ、その内面に塗布された粘着剤（図示せず）を介して基端部２４の外面に剥離可能に仮着されている。テープ１２では、図２に二点差線で示すように、自由端部２５を摘持してそれを縦方向外方へ引っ張ると、展開した自由端部２５が前域５の周縁部７から縦方向外方へ延びる。
【００２８】
図４，５は、着用状態で示すパッド１Ａの斜視図と、廃棄するために折り畳まれたパッド１Ａの斜視図とである。図４では、仰向けに寝た着用者を二点鎖線で示す。
【００２９】
パッド１Ａを着用させる一例としては、介護者が仰向けに寝ている着用者の臀部を持ち上げ、臀部の下にパッド１Ａの後域６を位置させた後、着用者の臀部を後域６の上に降ろす。次に、パッド１Ａの前域５を着用者の腹部の側に向かって旋回させる。パッド１Ａは、図４に示すように、前後域５，６の間に形成された折曲部１９で折れ曲がり、前域５が着用者の腹部の側に当接し、後域６が着用者の臀部に当接するとともに、折曲部１９近傍が着用者の股間部に当接する。パッド１Ａでは、その着用中に排泄された尿が表面シート２を透過して前域５のコア４に吸収され、排泄された大便に含まれる水分が表面シート２を透過して後域６のコア４に吸収される。
【００３０】
パッド１Ａは、それを着用した着用者が帯片１０，１１の把持部２３を両手で持ち、それら帯片１０，１１を矢印Ｍ１で示す縦方向外方へ引っ張ることで、パッド１Ａの前域５と後域６とを肌に密着させることができる。パッド１Ａは、着用者が帯片１０，１１を引っ張ることによって前後域５，６を肌に密着させることができるので、パッド１Ａに排泄物を確実に吸収させることができる。着用者は、それら帯片１０，１１の引っ張る力を加減することによって、パッド１Ａの肌に対する密着の程度を調節することができる。
【００３１】
パッド１Ａは、従来技術のそれと異なり、パンツを介してパッド１Ａを肌に密着させる必要はない。パッド１Ａは、その着用時に、それをパンツにのせてパンツとともに着用する必要はなく、パッド１Ａの後域６を着用者の臀部の下に敷くだけなので、パッド１Ａを簡単に着用させることができ、特に寝たきりの着用者の排泄物処理用として好適である。
【００３２】
パッド１Ａは、尿や大便が表面シート２の外面を拡散して前後域５，６の周縁部７，８に達したとしても、それらが周縁部７，８と周壁部９との間に形成されたポケット１７に収容されるので、尿や大便がパッド１Ａの外側に漏れてしまうことはない。パッド１Ａは、それら帯片１０，１１を縦方向外方へ引っ張ることで、第１固定部２１につながる周壁部９が伸長し、着用者の股間部に延びる周壁部９がそれら域５，６の上方へ起立する。パッド１Ａでは、起立した周壁部９が着用者の股間部に当接するので、着用者の股間部における排泄物の横漏れを確実に防ぐことができる。
【００３３】
パッド１Ａは、前域５に位置するコア４の肌当接側から上方への隆起高さ（厚み寸法）が後域６に位置するコア４の肌当接側から上方へのそれよりも大きいので、前域５に多量の尿が排泄されたとしても、尿を前域５に吸収させることができ、尿が前域５から後域６に向かって流動することはない。
【００３４】
パッド１Ａは、後域６の周縁部８に位置するコア４の肌当接側から上方への隆起高さ（厚み寸法）が後域６の残余部１８に位置するコア４の肌当接側から上方へのそれよりも大きいので、後域６を着用者の臀部の下に敷いたときに、後域６の周縁部８が着用者の臀部に当接し、着用者の荷重を周縁部８で分散させることができる。さらに、周縁部８におけるパッド１Ａのクッション性が高く、寝たきりの着用者の臀部に床擦れができることを防ぐことができる。
【００３５】
パッド１Ａは、その平面形状が前後域５，６の間がくびれた縦長円形を呈し、前後域５，６の間の横寸法が前後域５，６のそれよりも小さいので、帯片１０，１１を縦方向外方へ強く引っ張ったとしても、後域６が着用者の股間部に引っ掛かり、パッド１Ａが着用位置から不用意に外れてしまうことはない。
【００３６】
排泄物で汚れたパッド１Ａを廃棄するには、パッド１Ａを着用者から取り外し、図５に示すように、表面シート２を内側にした状態で折曲部１９を介してパッド１Ａを縦方向へ２つに折り畳み、前域５と後域６とを重ね合わせる。パッド１Ａを折り畳んだ後は、止着テープ１２の自由端部２５を基端部２４から剥がして縦方向へ伸ばし、粘着剤を介して自由端部２５を後域６の裏面シート３の外面に止着する。パッド１Ａは、折曲部１９を介して容易に折り畳むことができ、さらに、テープ１２を介してその折り畳まれた状態を維持することができる。パッド１Ａは、折り畳んだ状態のまま廃棄することができる。
【００３７】
図６，７は、他の一例として示す排泄物処理パッド１Ｂの斜視図と、図６のＶＩＩ−ＶＩＩ線矢視断面図とであり、図８は、図６のＶＩＩＩ−ＶＩＩＩ線矢視断面図である。図６では、縦方向を矢印Ｌ、横方向を矢印Ｍで示し、厚み方向を矢印Ｎで示す。
【００３８】
パッド１Ｂは、透液性表面シート２および不透液性裏面シート３と、それらシート２，３の間に介在する吸液性コア４とから構成されている。パッド１Ｂは、縦方向に並ぶ前域５および後域６を備え、それら域５，６を周方向へ延びる周縁部７，８と、それら域５，６の周縁部７，８の上方に位置して周方向へ延びる弾性的に伸縮可能な周壁部９とを有する。周縁部７，８は、表裏面シート２，３とコア４とから形成されている。
【００３９】
パッド１Ｂは、前後域５，６の周縁部７，８が方形を画き、その平面形状が実質的に縦長矩形を呈する。パッド１Ｂには、それを縦方向へ引っ張ることが可能な第１および第２帯片１０，１１と、パッド１Ｂの折り畳まれた状態（図５参照）を維持するための止着テープ１２とが取り付けられている。
【００４０】
表面シート２は、親水性繊維不織布１３から形成されている。裏面シート３は、互いに重なり合う２枚の疎水性繊維不織布１５，２６をラミネートした複合不織布から形成されている。不織布１５，２６は、それらの対向面が接着剤（図示せず）を介して断続的に固着されている。コア４は、図１のそれと同一のものであり、前域５と後域６とに位置し、その上下面が表裏面シート２，３の内面に接着剤（図示せず）を介して断続的に固着されている。
【００４１】
周壁部９は、前後域５，６の周縁部７，８全周を囲繞している。周壁部９は、前後域５，６の周縁部７，８から周方向内方へ延びる表面シート２と裏面シート３とから形成されている。表裏面シート２，３の互いに重なり合う部分では、それらシート２，３の内面どうしが接着剤（図示せず）を介して断続的に固着されている。
【００４２】
周壁部９には、その周方向へ実質的に環状を画く複数条の伸縮性弾性部材１６が収縮可能に取り付けられている。弾性部材１６は、周壁部９の周方向外方から周方向内方へ向かって所与寸法離間して並び、所定の倍率に伸長させた状態で周壁部９に取り付けられている。弾性部材１６は、裏面シート３を形成する不織布１５，２６の間に介在し、それら不織布１５，２６の対向面に接着剤（図示せず）を介して固着されている。周壁部９は、前後域５，６の周縁部７，８上面を覆うように、弾性部材１６の収縮力によって周縁部７，８の上方で周方向へ収縮かつ周方向内方へ狭窄している。周縁部９と周壁部７，８との間には、周方向内方へ向かって開口するポケット１７が形成されている。
【００４３】
前域５では、そこに位置するコア４の厚み寸法が後域６に位置するコア４のそれよりも大きく、コア４の肌当接側から上方への隆起高さが後域６に位置するコア４の肌当接側から上方へのそれよりも大きい。後域６では、その周縁部８に位置するコア４の厚み寸法が周縁部８を除く後域６の残余部１８に位置するコア４のそれよりも大きく、周縁部８に位置するコア４の肌当接側から上方への隆起高さが残余部１８に位置するコア４の肌当接側から上方へのそれよりも大きい。
【００４４】
なお、後域６の周縁部８に位置するコア４の厚み寸法は、前域５に位置するコア４のそれよりも小さく、後域６の周縁部８に位置するコア４の肌当接側から上方への隆起高さは、前域５に位置するコア４の肌当接側から上方へのそれよりも小さい。コア４の隆起高さ（厚み寸法）に差を設けるには、図１のパッド１Ａと同様に、コア４を形成するパルプや合成樹脂繊維の分量を多くしたり少なくすればよい。また、パルプや合成樹脂繊維の分量が同一であれば、コア４の隆起高さを小さくするためにコア４を厚み方向へ圧縮すればよい。
【００４５】
前域５と後域６との間には、パッド１Ｂを縦方向へ２つに折り畳むための横方向へ延びる折曲部１９が形成されている。折曲部１９は、コア４を除く表面シート２と裏面シート３とから形成されている。パッド１Ｂは、前域５における曲げ剛性が後域６における曲げ剛性よりも小さい。パッド１Ｂの前域５における曲げ剛性を後域６のそれよりも小さくするには、図１のパッド１Ａと同様に、コア４を形成するパルプや合成樹脂繊維の密度を後域６よりも前域５で低くすればよい。パッド１Ｂの前域５における曲げ剛性の値と後域６における曲げ剛性の値とは、図１のパッド１Ａのそれらと同一である。なお、それら曲げ剛性の測定方法は、図１のそれと同一である。
【００４６】

【発明の効果】
本発明にかかる使い捨て排泄物処理パッドによれば、それに取り付けられた帯片を着用者自身が縦方向外方へ引っ張ることで、パッドの前後域を肌に密着させることができ、排泄時にパッドに排泄物を確実に吸収させることができる。このパッドは、その着用時に、それをパンツにのせてパンツとともに着用する必要はなく、パッドの後域を着用者の臀部の下に敷くだけなので、パッドを簡単に着用させることができ、特に寝たきりの着用者の排泄物処理用として好適である。このパッドは、その周縁部の上方に位置して周縁部を囲繞する弾性的に伸縮可能な周壁部を有し、周縁部と周壁部との間にパッドの周方向内方へ向かって開口するポケットが形成されるので、尿や大便が表面シートの外面を拡散して前後域の周縁部に達したとしても、それらがポケットに収容され、尿や大便がパッドの外側に漏れてしまうことはない。
【００６０】
前域に位置するコアの肌当接側から上方への隆起高さが後域に位置するコアの肌当接側から上方へのそれよりも大きいパッドは、前域に多量の尿が排泄されたとしても、尿を前域に吸収させることができ、尿が前域から後域に向かって流動することはない。
【００６１】
後域の周縁部に位置するコアの肌当接側から上方への隆起高さが周縁部を除く後域の残余部に位置するコアの肌当接側から上方へのそれよりも大きいパッドは、後域の周縁部におけるパッドのクッション性を高くすることができ、後域を着用者の臀部の下に敷いたときに、後域の周縁部が着用者の臀部に当接し、着用者の荷重を周縁部で分散させることができる。
【００６２】
平面形状が前後域の間がくびれた縦長円形を呈するパッドは、前後域の間の横寸法が前後域のそれよりも小さく、帯片を縦方向外方へ強く引っ張ったとしても、後域が着用者の股間部に引っ掛かり、パッドが着用位置から不用意に外れてしまうことはない。
【００６３】
前後域の間に横方向へ延びる折曲部が形成されたパッドは、それを廃棄するときに、パッドを縦方向へ容易に折り畳むことができる。前域と後域とのいずれか一方に縦方向へ延びる止着テープが取り付けられたパッドは、折り畳まれたパッドの裏面シートの外面にテープの自由端部を止着することで、パッドの折り畳まれた状態を維持することができ、折り畳まれた状態のままパッドを廃棄することができる。

In the pad 1A, the area of the front region 5 is smaller than that of the rear region 6. The pad 1A has a pair of first and second strips 10, 11 that can be pulled in the longitudinal direction, and a fastening tape 12 for maintaining the folded state of the pad 1A (see FIG. 5). And are attached.
[0014]
The topsheet 2 is formed from a hydrophilic fiber nonwoven fabric 13. The back sheet 3 is formed of a composite sheet obtained by laminating a gas-impervious liquid-impermeable plastic film 14 and a hydrophobic fibrous nonwoven fabric 15 that overlap each other. In the back sheet 3, the film 14 is located on the side of the core 4, and the nonwoven fabric 15 is located outside the film 14. The film 14 and the nonwoven fabric 15 have their facing surfaces intermittently fixed via an adhesive (not shown).
[0015]
The core 4 is located in the front region 5 and the rear region 6, and its upper and lower surfaces are intermittently fixed to the inner surfaces of the front and back sheets 2 and 3 via an adhesive (not shown). The core 4 is a mixture of fluff pulp and superabsorbent polymer particles, or a mixture of fluff pulp, superabsorbent polymer particles and thermoplastic synthetic resin fibers, and is compressed to a predetermined thickness. Therefore, the rigidity of the core 4 is greater than those of the topsheet 2 and the backsheet 3. The core 4 is preferably entirely covered with a liquid-permeable sheet such as tissue paper or a hydrophilic fiber nonwoven fabric in order to prevent the core 4 from becoming out of shape and the polymer particles from falling off.
[0016]
The peripheral wall 9 surrounds the entire periphery 7, 8 of the front and rear regions 5, 6. Most of the peripheral wall portion 9 is formed of the back sheet 3 extending inward in the circumferential direction from the peripheral edges 7, 8 of the front and rear regions 5, 6. In the peripheral wall portion 9, the topsheet 2 slightly extends outward from the peripheral edge 4 a of the core 4, and the backsheet 3 further extends outside from the topsheet 2.

A plurality of stretchable elastic members 16 which are substantially annular in the circumferential direction are attached to the peripheral wall portion 9 so as to be contractable. The elastic members 16 are arranged at a predetermined distance from the outer side in the circumferential direction to the inner side in the circumferential direction of the peripheral wall portion 9, and are attached to the peripheral wall portion 9 in a state where the elastic members 16 are extended at a predetermined magnification. The elastic member 16 is interposed between the film 14 forming the back sheet 3 and the nonwoven fabric 15, and is fixed to their opposing surfaces via an adhesive (not shown). The peripheral wall portion 9 contracts in the circumferential direction and narrows inward in the circumferential direction above the peripheral portions 7 and 8 by the contracting force of the elastic member 16 so as to cover the upper surfaces of the peripheral portions 7 and 8 of the front and rear regions 5 and 6. I have. A pocket 17 that opens inward in the circumferential direction is formed between the peripheral edges 7 and 8 and the peripheral wall 9.
[0018]
In the front region 5, the thickness of the core 4 located there is larger than the thickness of the core 4 located in the rear region 6, and the height of the core 4 rising upward from the skin contact side is located in the rear region 6. It is larger than the protruding height of the core 4 from the skin contact side upward. In the pad 1A, a step is formed in the front region 5 and the rear region 6 in the thickness direction of the pad 1A. In order to make the raised height (thickness dimension) of the core 4 in the front region 5 larger than that of the core 4 in the rear region 6, the amount of pulp or synthetic resin fiber forming the core 4 is made smaller than that of the rear region 6. 5, the core 4 in the rear region 6 may be compressed in the thickness direction if the amount of pulp or synthetic resin fibers in the front and rear regions 5 and 6 is the same.
[0019]
In the rear region 6, the thickness of the core 4 located at the peripheral edge 8 is larger than the thickness of the core 4 located at the remaining portion 18 of the rear region 6 excluding the peripheral edge 8, and the core 4 located at the peripheral edge 8 is formed. Of the core 4 located in the remaining portion 18 is higher than the height of the core 4 located at the remaining portion 18 from the skin contact side. In the pad 1A, a step is formed at the peripheral portion 8 and the remaining portion 18 of the rear region 6 in the thickness direction of the pad 1A. In order to make the protruding height (thickness dimension) of the core 4 at the peripheral portion 8 of the rear region 6 larger than that of the core 4 at the remaining portion 18, the amount of the pulp or the synthetic resin fiber forming the core 4 should be reduced. If the amount of the pulp or the synthetic resin fiber is the same in the peripheral portion 8 and the residual portion 18 than in the peripheral portion 8, the core 4 of the residual portion 18 may be compressed in the thickness direction. The thickness of the core 4 located at the peripheral portion 8 of the rear region 6 is smaller than the thickness of the core 4 located at the front region 5, and the core 4 located at the peripheral portion 8 of the rear region 6 is in contact with the skin. The protruding height from the side to the upper side is smaller than the protruding height from the skin contact side of the core 4 located in the front region 5 to the upper side.
[0020]
Between the front region 5 and the rear region 6, a bent portion 19 extending in the horizontal direction for vertically folding the pad 1A into two so that the regions 5 and 6 overlap each other is formed. In the bent portion 19, the thickness dimension of the core 4 located there is smaller than the thickness dimension of the core 4 located in the front and rear regions 5 and 6, and the bending rigidity of the pad 1 A in the bent portion 19 in the front and rear regions 5 and 6. It is smaller than the bending rigidity of the pad 1A. In order to make the thickness dimension of the core 4 in the bent portion 19 smaller than that of the core 4 in the front and rear regions 5 and 6, the amount of pulp or synthetic resin fiber forming the core 4 is bent more than in the front and rear regions 5 and 6. The number may be reduced by the unit 19. In order to make the bending stiffness of the pad 1A in the bent portion 19 smaller than that of the pad 1A in the front and rear regions 5 and 6, the density of the pulp or the synthetic resin fiber forming the core 4 is set to be smaller than that in the front and rear regions 5 and 6. What is necessary is just to make it low in part 19.
[0021]
In the pad 1A, the bending rigidity in the front region 5 is smaller than the bending rigidity in the rear region 6. In order to make the bending stiffness in the front region 5 of the pad 1A smaller than the bending stiffness in the rear region 6, the density of the pulp or synthetic resin fiber forming the core 4 may be lower in the front region 5 than in the rear region 6. In the pad 1A, the bending rigidity of the front region 5 is in the range of 0.05 to 0.2 N / g, and the bending rigidity of the rear region 6 is in the range of 0.2 to 2.0 N / g.

If the bending stiffness of the pad 1A in the front region 5 is less than 0.05 N / g, when the pad 1A is pulled outwardly in the vertical direction via the strips 10 and 11 (see FIG. 4), the front region 5 of the pad 1A is not pulled. In some cases, a large number of irregularly bent portions may be formed. In the bent portion, the outer surfaces of the topsheet 2 abut against each other, and it is difficult for the urine to seep into the core 4, so that the excrement absorbing function of the pad 1A in the front region 5 cannot be fully utilized. When the bending stiffness of the pad 1A in the front region 5 exceeds 0.2 N / g, the flexibility of the pad 1A decreases, and when the front region 5 is applied to the skin of the wearer, an unpleasant feel is given to the wearer. There are cases.
[0023]
When the bending stiffness of the pad 1A in the rear region 6 is less than 0.2 N / g, the pad 1A is easily bent in the rear region 6, and when the wearer wears the pad 1A (see FIG. 4), the rear region 6 is partially formed. It may be laid under the wearer's buttocks in a bent state. When the bending stiffness of the pad 1A in the rear region 6 exceeds 2.0 N / g, the rear region 6 is unlikely to deform along the shape of the wearer's buttocks, and the load on the buttocks is concentrated at one location in the rear region 6, In some cases, the load on the buttocks cannot be distributed over the entire rear region 6. In addition, those bending rigidities were measured by the following method.
(1) The bending stiffness was measured using a bending stiffness measuring instrument and a horizontal plate. In addition, the machine name DIGTAL FORCE GAUGE manufactured by NIDEC-SHIMPO corporation was used as a bending rigidity measuring device.
(2) First, a method of measuring the bending stiffness of the front region 5 will be described. The pad 1A is placed on the horizontal plate so that the back sheet 3 is in contact with the horizontal plate, and the pad 1A is placed on the horizontal plate with the front half of the front region 5 of the pad 1A exposed outside from the edge of the horizontal plate. Fixed to.
[0024]
The arm of the measuring device is brought into contact with the front half of the front region 5, and the measuring device is gradually lowered below the horizontal plate. When the measuring device is lowered below the horizontal plate, the front half of the front region 5 is pushed down below the horizontal plate by the arm of the measuring device, and the front half gradually bends below the horizontal plate. As the bending stiffness of the pad 1A in the front region 5, the numerical value indicated by the measuring instrument when the front half of the front region 5 bent below the horizontal plate makes an angle of 45 degrees with the horizontal plate was used.
(3) Next, a method for measuring the bending stiffness of the rear region 6 will be described. The pad 1A is placed on the horizontal plate so that the back sheet 3 is in contact with the horizontal plate, and the pad 1A is placed on the horizontal plate in a state where the rear half of the rear area 6 of the pad 1A is exposed outward from the edge of the horizontal plate. Fixed to.
[0025]
The arm of the measuring device is brought into contact with the rear half of the rear region 6, and the measuring device is gradually lowered below the horizontal plate. When the measuring instrument is lowered below the horizontal plate, the rear half of the rear region 6 is pushed down below the horizontal plate by the arm of the measuring instrument, and the rear half gradually bends below the horizontal plate. As the bending stiffness of the pad 1A in the rear region 6, the numerical value indicated by the measuring instrument when the rear half of the rear region 6 bent below the horizontal plate makes an angle of 45 degrees with the horizontal plate was used.
[0026]
The first and second strips 10 and 11 are arranged in the front region 5 and are arranged side by side with a given distance. The strips 10 and 11 are formed from a non-stretchable fibrous nonwoven fabric 20. The strips 10 and 11 include a first fixing portion 21 fixed to the peripheral wall portion 9 surrounding the peripheral portion 7 of the front region 5, a second fixing portion 22 fixed to the peripheral portion 7 of the front region 5, And a grip 23 extending vertically outward from the peripheral edge 7 of the front region 5.
