- the at least one lowermost elastic member positioned at the end extends in a tensioned state along the front edge portion of each of the pair of leg openings, and is formed at a front portion of the crotch region between the pair of leg openings.
- a plurality of rear elastic members extending in the width direction of the rear waist region and spaced apart from each other in the vertical direction of the rear waist region are attached to the rear portion, and the lowermost of the rear elastic members
- the at least one lowermost elastic member located in the section extends in a tensioned state along the rear edge portion of each of the pair of leg openings, and in the rear portion of the crotch region between the pair of leg openings. It extends in a relaxed state as compared with the rear edge portion.
- the body fluid-absorbing panel includes a front end portion that is bonded to the inner surface of the front waistline region, a rear end portion that is bonded to the inner surface of the rear waistline region, the front end portion, and the rear An intermediate portion that is between the end portions and in a non-bonded state with respect to the inner surface of the crotch region. Containment on both sides of the body fluid absorbent panel in the width direction has a propensity to stand up from the inner surface of the body fluid absorbent panel under the contracting action of an elastic member extending between the front end portion and the rear end portion. A flap is formed.
- both side portions of the chassis in the width direction extend to a lower end portion of the body fluid absorbent panel located inside the crotch region in the vertical direction.
- the front elastic member and the rear elastic member are included separately from the members forming the front and rear waist regions.
- a panel member that does not occur is interposed between the front waistline region and the rear waistline region.
- the lowermost elastic member of the front elastic member and the lowermost elastic member of the rear elastic member do not extend to the inner crotch portion of the crotch region, and the crotch Crosses the area.
- the inner crotch portion of the crotch region does not include an elastic member extending in the front-rear direction in a tension state.
- the front waistline region is pleated uniformly in the entire width direction by contraction of the front elastic member in a portion below the front end portion of the body fluid absorbent panel. It is formed and the width is uniform.
- the rear waistline region has a pleat uniformly in the entire width direction due to contraction of the elastic member in a portion below the rear end portion of the body fluid absorbent panel. It is formed and the width is uniform.
- both ends of the body fluid-absorbing panel having the containment flaps are joined to the inner surfaces of the front and rear waist regions of the pants-type chassis, respectively, in the crotch region of the body fluid-absorbing panel.
- An intermediate part and the crotch region of the chassis are in a non-joined state.
- the lowermost elastic members positioned in the front portion and the rear portion of the chassis and extending in the width direction of the chassis extend along the front edge portions of the pair of leg openings or along the rear edge portions. It extends.
- FIG. 4 is a sectional view taken along line IV-IV in FIG. 3.
- FIG. 6 is a perspective view of the diaper of FIG. 5 in which the panel member is in an extended state.
- deployment diaper obtained by the diaper of FIG.
- FIG. 1 is a partially broken perspective view of a disposable pant-type diaper 1, wherein the front-rear direction, the width direction, and the height direction of the diaper 1 are indicated by double-headed arrows A, B, and C.
- the height direction C is sometimes referred to as the vertical direction C.
- the diaper 1 has a pants-type chassis 2 and a body fluid-absorbing panel 3 attached to the inner surface 2a of the chassis 2.
- the chassis 2 can be called trunks-type pants or boxer-type pants, and has a front waistline region 6, a rear waistline region 7, and a crotch region 8 interposed between the front and rear waistline regions 6, 7. .
- the chassis 2 is also folded in two at the crotch region 8, and the front and rear waist regions 6, 7 are overlapped with each other at the side edges 6 a, 7 a and joined to each other at the welding site 11.

Description
この発明は、使い捨てのおむつや使い捨ての失禁患者用パンツとして使用可能な使い捨てのパンツ型着用物品に関する。
パンツ型のシャシーと、その内面に接合された体液吸収性パネルとを有する使い捨てのパンツ型着用物品は、公知でもあり周知でもある。
例えば、特開2006-141494号公報(特許文献1)に記載のパンツ型おむつは、外装シートと砂時計型の液吸収体とを含む。外装シートは、股下域において二つに折り重ねられていてトランクス型に近似したパンツ形状のシャシーを形成し、液吸収体は外装シートの内面に接合されている。パンツ型おむつの脚回り開口を形成するために外装シートに形成された湾入部の周縁には、弾性部材が取り付けられている。外装シートにはまた、前身頃部分と後身頃部分とに横方向へ延びる弾性部材が取り付けられている。
特許文献1に記載のパンツ型おむつは、外装シートに取り付けられた弾性部材の作用によって外装シートと一体の液吸収体を身体に密着させようとするものであって、外装シートと液吸収体とが別体で用意されているものではあっても、パンツ型おむつとしては、それを着用した後に液吸収体を身体の上方に引き上げようとすると、外装シートも引き上げられて、外装シートの湾入部周縁に取り付けられている脚回り用の弾性部材が脚の付け根に常に接近するということがある。したがって、液吸収体の両側部に弾性部材の作用によって起立する防漏堤が形成されている場合には、脚回り弾性部材がそのような状態になると防漏堤の起立が妨げられて、おむつでは体液の横漏れが生じ易くなる。
この発明では、体液吸収性パネルの防漏堤の起立が脚回り開口の周縁部に取り付けられた弾性部材によって妨げられることがないように改良された使い捨てのパンツ型着用物品の提供を課題にしている。
前記課題を解決するための、この発明は、前胴回り域と後胴回り域と股下域とを含んでいてこれら各域が着用者の肌と向かい合う内面を有するパンツ形状のシャシーと、前記股下域を中央にして前記前胴回り域と前記後胴回り域とに延びて前記シャシーの前記内面に接合されている体液吸収性パネルとを備え、前記シャシーには胴回り開口と一対の脚回り開口とが形成されている使い捨てのパンツ型着用物品である。
かかるパンツ型着用物品において、この発明の特徴は、以下のとおりである。すなわち、前記シャシーは、前記前胴回り域と前記股下域の一部分とを含む前方部分と,前記後胴回り域と前記股下域の一部分とを含む後方部分とを有する。前記前方部分には、前記前胴回り域の幅方向へ延びるとともに前記前胴回り域の上下方向において互いに離間している複数条の前方弾性部材が取り付けられていて、前記前方弾性部材のうちで最下部に位置する少なくとも一条の最下部弾性部材は、前記一対の脚回り開口それぞれの前縁部分に沿って緊張した状態で延びるとともに、前記一対の脚回り開口の間にある前記股下域の前方部分では前記前縁部分に比べて弛緩した状態で延びている。前記後方部分には、前記後胴回り域の幅方向へ延びるとともに前記後胴回り域の上下方向において互いに離間している複数条の後方弾性部材が取り付けられていて、前記後方弾性部材のうちで最下部に位置する少なくとも一条の最下部弾性部材は、前記一対の脚回り開口それぞれの後縁部分に沿って緊張した状態で延びるとともに、前記一対の脚回り開口の間にある前記股下域の後方部分では前記後縁部分に比べて弛緩した状態で延びている。前記体液吸収性パネルは、前記前胴回り域の前記内面に対して接合状態にある前端部と、前記後胴回り域の前記内面に対して接合状態にある後端部と、前記前端部と前記後端部との間にあって前記股下域の前記内面に対して非接合状態にある中間部とを有する。前記体液吸収性パネルの前記幅方向の両側には、前記前端部と前記後端部との間に延びている弾性部材の収縮作用下に前記体液吸収性パネルの内面からの起立性向を有する封じ込めフラップが形成されている。
この発明の実施態様の一つにおいて、前記シャシーの前記幅方向における両側部分は、前記上下方向において、前記股下域の内側に位置している前記体液吸収性パネルの下端部分にまで延びている。
この発明の実施態様の一つにおいて、前記シャシーの前記幅方向における両側部分では、前記前後胴回り域それぞれを形成している部材とは別体であって前記前方弾性部材および前記後方弾性部材を含むことのないパネル部材が前記前胴回り域と前記後胴回り域との間に介在している。
この発明の実施態様の一つにおいて、前記前方弾性部材における前記最下部弾性部材と前記後方弾性部材における前記最下部弾性部材とは、前記股下域のうちの内股部分にまでは延びることなく前記股下域を横断している。
この発明の実施態様の一つにおいて、前記股下域の前記内股部分には、緊張状態で前後方向へ延びる弾性部材が含まれていない。
この発明の実施態様の一つにおいて、前記前胴回り域は、前記体液吸収性パネルの前記前端部よりも下方の部分において、前記前方弾性部材の収縮によって前記幅方向の全体にひだが一様に形成されていて、幅も一様である。
この発明の実施態様の一つにおいて、前記後胴回り域は、前記体液吸収性パネルの前記後端部よりも下方の部分において、前記弾性部材の収縮によって前記幅方向の全体にひだが一様に形成されていて、幅も一様である。
この発明に係る使い捨てのパンツ型着用物品では、封じ込めフラップを有する体液吸収性パネルの両端部それぞれがパンツ型のシャシーの前後胴回り域それぞれの内面に接合されていて、体液吸収性パネルの股下域である中間部とシャシーの股下域とは非接合状態にある。しかも、シャシーの前方部分と後方部分とに位置してシャシーの幅方向へ延びる最下部弾性部材のそれぞれは、一対の脚回り開口それぞれの前縁部分に沿って延びているか、後縁部分に沿って延びている。このようなパンツ型着用物品では、それを着用した後に体液吸収性パネルを身体の上方へ引き上げようとするときに、脚回り弾性部材として作用する前方部分と後方部分の最下部弾性部材は、体液吸収性パネルに引きずられ上昇することがないから、体液吸収性パネルの封じ込めフラップの起立が脚回り弾性部材によって妨げられるということがない。
この発明に係る使い捨てのパンツ型着用物品として使い捨てのパンツ型おむつを例にとり、添付の図面を参照してこの発明の詳細を説明すると、以下のとおりである。
図1は、使い捨てのパンツ型おむつ1の部分破断斜視図であって、おむつ1の前後方向と幅方向と高さ方向とが双頭矢印A,B,Cで示されている。ただし、以下の説明では、高さ方向Cを上下方向Cということもある。おむつ1は、パンツ型のシャシー2とシャシー2の内面2aに取り付けられている体液吸収性パネル3とを有する。シャシー2は、トランクス型パンツまたはボクサータイプのパンツと呼ぶことのできるもので、前胴回り域6と、後胴回り域7と、これら前後胴回り域6,7の間に介在する股下域8とを有する。シャシー2はまた股下域8において二つに折り重ねられていて、前後胴回り域6,7は互いの側縁部6a,7aが合掌状に重なり合い、溶着部位11において互いに接合している。かようなシャシー2には、胴回り開口12と、一対の脚回り開口13とが形成されている。前後胴回り域6,7には、後記前方弾性部材21と後方弾性部材22との収縮によって、幅方向Bにおいて起伏を繰り返すひだ15が多数形成されている。シャシー2の内側では、股下域8の近傍で二つに折り重ねられ体液吸収性パネル3が上下方向Cへ延びている。体液吸収性パネル3の股下域である中間部33は、シャシー2の股下域8から寸法Dだけ離間している。
図2は、図1のおむつ1において側縁部6a,7aに対して形成されていた溶着部位11における接合を解いて、前後胴回り域6,7と股下域8とを前後方向Aと幅方向Bとに伸展して得られる展開おむつ1aの部分破断平面図である。ただし、図2では、体液吸収性パネル3について、その輪郭のみが仮想線12aで示されているので、図2は、実質的な意味において、シャシー2の部分破断平面図ということのできるものである。図2におけるシャシー2は、互いに重なり合いホットメルト接着剤(図示せず)を介して接合している内面シート10aと外面シート10bとを含んでいる。内面シート10aと外面シート10bとの間には、幅方向Bへ緊張した状態で延びる複数条の前方弾性部材21と複数条の後方弾性部材22とがある。これら弾性部材21,22は、内面シート10aおよび/または外面シート10bにホットメルト接着剤(図示せず)を介して伸長状態、すなわち緊張した状態で接合している。前方弾性部材21は、展開おむつ1aの前後方向Aの寸法を二等分する中心線Pによって画成される前方部分16に位置するもので、その前方部分16には前胴回り域6と股下域8の一部分とが含まれている。後方弾性部材22は、中心線Pによって画成される後方部分17に位置するもので、その後方部分17には後胴回り域7と股下域8の一部分とが含まれている。
前方弾性部材21は、図1における胴回り開口12の周縁部に沿って互いに並行して延びる複数条の上方弾性部材21aと、図1において上方弾性部材21aの下方に位置する複数条の下方弾性部材21bとを含んでいる。その下方弾性部材21bのうちで最下部に位置する少なくとも一条の最下部弾性部材21cは、脚回り開口13(図1参照)の周縁部分23のうちで前方部分16に位置している前縁部分23aに沿って延びるとともに一対の脚回り開口13の間にある股下域8のうちの前方部分8aを幅方向Bにおいて横断している。かような最下部弾性部材21cは、前縁部分23aに対しては高い伸長率で取り付けられていて緊張した状態にあるが、股下域8の前方部分8aに対しては、前縁部分23aにおけるよりも低い伸長率または非伸長状態で取り付けられていて前縁部分23aにおける状態に比べて弛緩した状態にある。
後方弾性部材22は、胴回り開口12の周縁部に沿って互いに並行して延びる複数条の上方弾性部材22aと、図1において上方弾性部材22aの下方に位置する複数条の下方弾性部材22bとを含んでいる。その下方弾性部材22bのうちで最下部に位置する少なくとも一条の最下部弾性部材22cは、脚回り開口13の周縁部分23のうちで後方部分17に位置している後縁部分23bに沿って延びるとともに、一対の脚回り開口13の間にある股下域8のうちの後方部分8bを横断している。かような最下部弾性部材22cは、後縁部分23bに対して高い伸長率で取り付けられていて緊張した状態にあるが、股下域8の後方部分8bに対しては後縁部分23bにおけるよりも低い伸長率または非伸長状態で取り付けられていて、後縁部分23bにおける状態に比べて弛緩した状態にある。
図2において、シャシー2に対して画かれた仮想線12b,12cは体液吸収性パネル3を内面シート10aに対して接合するときのホットメルト接着剤14の塗布域を示している。図から明らかなように、体液吸収性パネル3は、仮想線12bと12cとで示された範囲においてのみシャシー2に接合されるもので、シャシー2の股下域8とその近傍とに対しては非接合状態にある。
図3,4において、図3は体液吸収性パネル3の部分破断平面図であり、図4は図3におけるIV-IV線切断面を示す図である。図3の体液吸収性パネル3は、図2における前後方向Aと幅方向Bとに同じ前後方向Aと幅方向Bとを有し、前後方向Eに長く形成されていて前端部31と、後端部32と、両端部31,32の間の中間部33とを有する。図4から明らかなように、体液吸収性パネル3は、透液性のトップシート36と不透液性のバックシート37と、これら両シート36,37の間に介在する体液吸収性の芯材38とを有する。トップシート36とバックシート37とは、芯材38の周縁から延出して互いに重なり合い、ホットメルト接着剤(図示せず)を介して互いに接合して体液吸収性パネル3の周縁部分3aを形成している。体液吸収性パネル3の幅方向Bの両側それぞれには、互いに重なり合うトップシート36とバックシート37とをトップシート36を内側にして折曲部39で折曲することにより、封じ込めフラップ41が形成されている。封じ込めフラップ41は、折曲部39の近傍に位置する近位縁42と、近位縁42に並行する遠位縁43とを有する。遠位縁43では、バックシート37を折り重ねることによりスリーブ44が形成され、スリーブ44の内側には一条または複数条の弾性部材46が伸長状態で取り付けられている。かような封じ込めフラップ41は、その前端部41aと後端部41bとがホットメルト接着剤48を介して体液吸収性パネル3の前端部31と後端部32との内面に接合し、封じ込めフラップ41の中間部41cが弾性部材46の収縮とともに体液吸収性パネル3の中間部33から中間部33の上方へ起立可能な状態にある。このように形成されている体液吸収性パネル3は、それが図2のシャシー2の内面シート10aに載せられて、前端部31と後端部32とが、仮想線12bと仮想線12cとで示されている部位に対してホットメルト接着剤14を介して接合される。
体液吸収性パネル3が接合された図2のシャシー2は、体液吸収性パネル3を内側にして中心線Pに沿って折り重ねられ、前胴回り域6の側縁部6aと後胴回り域7の側縁部7aとが溶着部位11において溶着されると、図1のおむつ1となる。おむつ1となったときの体液吸収性パネル3は、それが図2の中心線Pに沿って折曲されてU字形ないしV字形を画くようになると、封じ込めフラップ41における弾性部材46が収縮することに伴い、内面シート10aに載せられて中心線Pで折曲された中間部33が内面シート10aからシャシー2における股下域8の上方に位置するように動き、寸法Dの間隔が生じる(図1参照)。図1のおむつ1ではまた、そのような体液吸収性パネル3の股下域である中間部33に対して、シャシー2における脚回り開口13が高さ方向Cにおいてほぼ同じ位置となるように形成されているか、または下方となるように形成されている。
このような図1のおむつ1では、体液吸収性パネル3の中間部33をシャシー2の内部において自由に動かすことができる。それゆえ、おむつ1を着用するために脚を脚回り開口13に挿入しようとして体液吸収性パネル3が邪魔になるときには、体液吸収性パネル3が邪魔にならないようにその脚や手によって体液吸収性パネル3を動かすことができる。着用した後のおむつ1では、体液吸収性パネル3の封じ込めフラップ41における遠位縁43を着用者の鼠蹊部や脚回りにフィットさせようとして体液吸収性パネル3を持ち上げたときに、その体液吸収性パネル3の動きに引きずられてシャシー2の最下部弾性部材21cや22cが上方へ移動したり、シャシー2の股下域8が上方へ移動したりするということがないので、最下部弾性部材21c,22cや股下域8が体液吸収性パネル3をおむつ1の下方から強く押して、封じ込めフラップ41の起立を妨げるという問題は生じない。
おむつ1ではまた、最下部弾性部材21cがおむつ1の前方部分16おいて幅方向Bへ延びているのみで弾性的に伸長された状態で脚回り開口13を囲むことがなく、最下部弾性部材22cもまた弾性的に伸長された状態で脚回り開口13を囲むことがない。すなわち、股下域8の前方部分8aと後方部分8bとの間にあっておむつ着用者の内股と向かい合う部位51(図2参照)はシャシー2の内股部分であって、そこには内股部分の前後方向へ伸長状態で延びる弾性部材が存在しないから、この部位51は、着用者の脚回りに、具体的には着用者の内股に弾性的に密着することがない。このような部位51は、内股との間に間隙を作り易く、その間隙は図1のおむつ1を着用するときにシャシー2の内外に通じる通気性の部位として作用することが可能で、シャシー2の内部が蒸れることを防ぐように作用する。
また、最下部弾性部材21cと22cとが脚回り周り開口13の前方周縁部23aと後方周縁部23bとにおいては伸長率が高い状態にあることによって緊張した状態にあり、股下域8の前方部分8aと後方部分8bとにおいては伸長率が低い状態にあるか非伸長状態にあることによって弛緩した状態にあると、おむつ1では、幅方向Bへ伸長状態で延びる弾性部材の収縮によって股下域8にひだができて股下域8の外観が悪くなるということを防いだり、そのひだによって股下域8の幅方向Bにおける見かけの寸法が小さくなって体液吸収性パネル3がシャシー2の外側から見え易くなることを防いだりすることができる。
おむつ1はまた、前胴回り域6や後胴回り域7が体液吸収性パネル3と重なり合っていても、体液吸収性パネル3と接合していない部分6b,7b(図2参照)では、前方弾性部材21bや後方弾性部材22bの収縮が体液吸収性パネル3によって拘束されるということがなく、幅方向Bの全体にわたって一様に収縮することが可能になる。そのような部分6b,7bでは、ひだ15が幅方向Bの全体に一様に形成されるとともに、幅方向Bの寸法、すなわち幅も一様になって、シャシー2における側縁部6aや7aが直線状に延びるものになり、外観のよいおむつ1を得ることができる。
図5は、実施態様の一例を示す図1と同様な図である。図5におけるパンツ型おむつ1は、図1のシャシー2とは異なる態様のシャシー2を有している。図5のシャシー2の前胴回り域66と後胴回り域67との間に側部パネル61が介在し、図ではその側部パネル61が折り畳まれた状態にある。前胴回り域66と後胴回り域67とは、図1,2と同様のレイアウトで配置された前方弾性部材21と後方弾性部材22とを内面シート10aと外面シート10bとの間に含んでいて、幅方向Bにおいて弾性的に伸長・収縮する。側部パネル61は、弾性的な伸長性を持たない、いわゆる非弾性シート、または弾性的な伸長性を有する、いわゆる弾性シートのいずれかによって形成することができる。
図6は、図5において折り畳まれていた側部パネル61を胴回り方向へ伸展させてあるおむつ1の斜視図であって、おむつ1はこの状態で着用される。側部パネル61は、上下方向Cへ延びる両側縁部62,63のそれぞれがシャシー2における前胴回り域66の側縁部66aと後胴回り域67の側縁部67aとのそれぞれに接合している。このようなおむつ1の前胴回り域6は、シャシー2の前胴回り域66と、一対の側部パネル61それぞれの一部分とによって形成されている。また、おむつ1の胴回り開口12と脚回り開口13とは、シャシー2と一対の側部パネル61とによって画成されている。
図7は、図6のおむつ1において、シャシー2の前胴回り域66の側縁部66aと側部パネル61の側縁部62との接合を解いて、おむつ1を前後方向Aと幅方向Bとに伸展して得られる展開おむつ1aの部分破断平面図である。展開おむつ1aのシャシー2は、内面シート10aと、外面シート19bと、前方弾性部材21と、後方弾性部材22とを含むことにおいて、図2の展開おむつ1aと同じである。ただし、図7における展開おむつ1aにおいては、最下部弾性部材21cと22cとが脚回り開口13の周縁部分23のうちでも、シャシー2によって形成されている前縁部分23aと後縁部分23bとにのみ存在している。このような図6の態様にある最下部弾性部材21c,22cも、図1における最下部弾性部材21cや22cと同様に機能することが可能である。
図示例のパンツ型おむつ1において、シャシー2の内面シート10aと外面シート10bとには、熱可塑性合成繊維で形成された不織布や織布、熱可塑性合成樹脂で形成されたフィルム、不織布どうしの積層体、不織布とフィルムとの積層体等を使用することができる。内面シート10aと外面シート10bは通気性のものであることが好ましく、通気不透液性のものであることがより好ましい。体液吸収性パネル3における透液性のトップシート36には、熱可塑性合成繊維で形成された不織布や熱可塑性合成樹脂で形成された開孔フィルムを使用することができる。不透液性のバックシート37には、熱可塑性合成樹脂で形成されたフィルムを使用することができる。体液吸収性パネル3における芯材38には、粉砕パルプや粉砕パルプと高吸水性ポリマー粒子との混合物等の吸水性材料をティッシュペーパや透液性不織布で形成されたタッピングシートで被覆したものを使用することができる。
図示例において使い捨てのパンツ型おむつ1を例にとって説明したこの発明に係るパンツ型着用物品は、失禁患者用パンツ、トレーニングパンツ等として使用することもできる。
