本考案は、使用状態において横断面山形のバリヤーカフスを有する紙おむつに 関する。 The present invention relates to a paper diaper having barrier cuffs having a chevron cross section in a used state.
【０００２】[0002]
たとえば、特開昭６２−２５０２０１号公報には、フラップ部分に一枚のバリ ヤーシートを固着して近位端とし、自由の遠位端に弾性伸縮部材を設けた構造、 およびその変形例として、トップシートを延在させて、フラップ部分の途中に折 り畳んで起立させてバリヤーカフスとし、その折り畳み部分の側縁を遠位端とし 、起立箇所を近位端とした構造も開示している。他にも多くの提案があるが、前 記の公報技術を基本として、そのバリエーションが多い。 For example, Japanese Patent Laid-Open No. 62-250201 discloses a structure in which one barrier sheet is fixed to the flap portion as a proximal end, and an elastic elastic member is provided at a free distal end. Also disclosed is a structure in which the top sheet is extended and folded in the middle of the flap portion to stand up to form a barrier cuff, with the side edge of the folded portion as the distal end and the standing portion as the proximal end. .. There are many other proposals, but there are many variations based on the publication technology mentioned above.
【０００３】[0003]
しかし、前述の公報記載の紙おむでは、使用時において、内方に傾斜して起立 するバリヤーカフスが伏倒し易く、もって、脚回り部分とバリヤーカフスの自由 縁との間が離間することが多い。その結果、その離間部分を軟便または尿が越え てしまい、横漏れの原因となる。さらに前記公報では、バリヤーカフスの近位端 と吸収体の側縁部分との間にポケット空間またはチャンネルを形成することが、 軟便を防止する上で有効であると開示しているが、本考案者らの知見によれば、 その有効性が確認できなかった。 However, in the disposable diaper described in the above-mentioned publication, the barrier cuffs that incline and stand upright tend to fall down during use, so that the leg parts and the free edges of the barrier cuffs may be separated. Many. As a result, loose stool or urine will pass over the separated portion, causing side leakage. Further, the above-mentioned publication discloses that forming a pocket space or channel between the proximal end of the barrier cuff and the side edge portion of the absorbent is effective in preventing loose stool. According to their findings, its effectiveness could not be confirmed.
【０００４】 そこで、本考案者等は、先に横断面山形のバリヤーカフスを有する構造の紙お むつを、特願平３−１５４７４８号公報として提案するとともに、実願平３−６ ３９７４号公報において、バリヤーシートの内側部分と外側部分とを相互に固定 して二重のバリヤーシートとすることにより、尿の横漏れ防止効果を高めるとと もに、バリヤーカフスの形状保持性を良好とし、さらに透液性シートからの尿の 伝播を防止した。Therefore, the present inventors previously proposed a paper diaper having a structure having barrier cuffs having a chevron cross-section as Japanese Patent Application No. 3-154748 and Japanese Patent Application No. 3-6394. In the above, by fixing the inner part and the outer part of the barrier sheet to each other to form a double barrier sheet, the effect of preventing lateral leakage of urine is enhanced and the shape retention of the barrier cuff is improved. Furthermore, the transmission of urine from the liquid permeable sheet was prevented.
【０００５】 これらの公報に係るバリヤーシートはその内方部分に配設される弾性伸縮部材 の収縮力により起立され、その自由側縁がきっちりと着用者の肌に密着すること により横漏れが防止される。しかしバリヤーシートを前記弾性伸縮部材のみに頼 り起立させようとすると、いきおいその収縮力が強くなるため、着用状態で弾性 伸縮部材が脚回りを締め付ける結果となり、装着者は圧迫感や肌への食い込み等 により痛みを感ずるようになる。また、前記弾性伸縮部材のみに頼りバリヤーシ ートを起立させると、バリヤーシートに張った状態となりその自由部分に余裕が なくなるため、着用者の動きに追従できずに隙間を生じ、そこから横漏れを起こ す場合もある。The barrier sheet according to these publications is erected by the contracting force of the elastic stretchable member disposed in the inner portion thereof, and its free side edges are firmly attached to the wearer's skin to prevent side leakage. To be done. However, if an attempt is made to stand up the barrier sheet by relying only on the elastic stretchable member, the contraction force will be strengthened, and as a result, the elastic stretchable member tightens around the legs in the worn state, which causes the wearer to feel pressure and to the skin. You will feel pain due to the bite. Also, if the barrier sheet is erected only by the elastic member, it will be in a state of being stretched on the barrier sheet, and there will be no room in the free part of the barrier sheet. May occur.
【０００６】 したがって、本考案の主たる課題は、前記弾性伸縮部材による肌への圧迫を無 くするとともに、肌への追随性を良好とし、さらに堰止め効果の高い紙おむつを 提供することにある。Therefore, a main object of the present invention is to provide a paper diaper which has no elastic pressure member on the skin, has good conformability to the skin, and has a high blocking effect.
【０００７】[0007]
前記課題は、不透液性シートと透液性シートとで吸収体を被包し、かつ両側部 に使用面側に突出するバリヤーカフスを有する紙おむつにおいて、 前記各バリヤーカフスは、撥水性または不透液性のバリヤーシートにより形成 され、このバリヤーシートは内折りされて二重シートとされ、このバリヤーシー トの内側部分は少なくとも脚回り部分において内起立線をもって透液性シートに 対して固定され、前記バリヤーシートの外側部分は少なくとも脚回り部分のフラ ップ部分において不透液性シートまたは延在する透液性シートに対して外起立線 をもって固定され、これら起立線から起立した起立端部に紙おむつ長手方向に延 在する起立用弾性伸縮部材を有し、 さらに透液性シートの側縁は吸収体の側面を包むようにしてバリヤーカフスの 起立部分の下方まで延在し、そのバリヤーカフスの下方部分において不透液性シ ートに対して固定され、この透液性シートと不透液性シートの固定部分に紙おむ つの長手方向に延在する形状保持用弾性伸縮部材が設けられているとともに、こ の形状保持用弾性伸縮部材の外方側に隣接して起立補助用弾性伸縮部材が設けら れていることで解決できる。 また、好ましくは前記形状保持用弾性伸縮部材と起立補助用弾性伸縮部材との 間隔が３〜５mmとし、前記起立用弾性伸縮部材と前記起立補助用弾性伸縮部材の 収縮力の分担比を３：７〜５：５とする。 The problem is a paper diaper having a liquid-permeable sheet and a liquid-permeable sheet covering an absorbent body and having barrier cuffs on both sides that project toward the use surface side, wherein each of the barrier cuffs is water-repellent or impermeable. It is formed by a liquid-permeable barrier sheet, and this barrier sheet is folded inward to form a double sheet, and the inner part of this barrier sheet is fixed to the liquid-permeable sheet with the inner rising line at least at the leg parts. The outer portion of the barrier sheet is fixed to the liquid-impermeable sheet or the extending liquid-permeable sheet with an outer standing line at least in the flap portion of the leg part, and standing end portions standing upright from these standing lines. Has a standing elastic elastic member extending in the longitudinal direction of the paper diaper, and the side edge of the liquid-permeable sheet wraps the side surface of the absorbent body to form a barrier cuff. It extends below the standing portion and is fixed to the liquid impermeable sheet at the lower part of the barrier cuff, and the liquid permeable sheet and the fixed portion of the liquid impermeable sheet are fixed to the longitudinal direction of the disposable diaper. It is possible to solve the problem by providing the elastic elastic member for shape retention that extends to the inner side and the elastic elastic member for standing up assistance adjacent to the outer side of the elastic elastic member for shape retention. Further, preferably, the distance between the shape-retaining elastic stretchable member and the stand-up assisting elastic stretchable member is set to 3 to 5 mm, and the contraction force sharing ratio between the stand-up elastic stretchable member and the stand-up assisting elastic stretchable member is 3: 7 to 5: 5.

本考案に係るバリヤーカフスは、バリヤーシートが内折りされてその自由側縁 部分に起立用弾性伸縮部材が配設されるため、起立状態では不等辺三角形の頂点 が中心より内方に位置したバリヤーカフスとなり外側に反転することが確実に防 止される。また、透液性シートの側縁を吸収体の側面を包むようにしてバリヤー カフスの起立部分の下方まで延在し、そのバリヤーカフスの下方の部分において 不透液性シートに対して固定されているため、吸収体の横ずれが防止されるとと もに、透液性シートに吸収された尿の幅方向への拡散性が良好となる。また、透 液性シートの側縁は、バリヤーカフスの下方の部分において不透液性シートに対 して固定されるため、それ以上尿が拡散せずに横漏れが防止できる。 さらに、透液性シートと不透液性シートとの固定部分に形状保持用弾性伸縮部 材が設けられるとともに、これの外方側に隣接して起立補助用弾性伸縮部材が設 けられ、バリヤーカフスの起立に関しては、前記起立用弾性伸縮部材と起立補助 用弾性伸縮部材とが収縮力を分担するため、肌と直接当接する前記起立用弾性伸 縮部材が着用者に圧迫・締付感を与えることがなくなる。また、形状保持用弾性 伸縮部材により吸収体を折り曲げて舟形とし、さらに前記起立補助用弾性伸縮部 材がバリヤーカフス全体を上方側に持ち上げることになるため、肌に直接当接す る起立用弾性伸縮部材が着用者の動きに追随し易くなる。さらに、前記バリヤー カフスによる堰止め効果とともに、吸収体とサイドフラップ部で堰を形成するた め高い堰止め効果を期待することができる。 In the barrier cuff according to the present invention, since the barrier sheet is folded inside and the elastic elastic members for standing are arranged at the free side edge portions thereof, the barrier in which the apex of the isosceles triangle is located inward from the center in the standing state. Being a cuff, it is surely prevented from turning over. Further, since the side edge of the liquid-permeable sheet extends below the standing portion of the barrier cuff so as to wrap the side surface of the absorbent body, and is fixed to the liquid-impermeable sheet at the lower portion of the barrier cuff. The lateral displacement of the absorbent body is prevented, and the diffusibility of the urine absorbed by the liquid permeable sheet in the width direction is improved. In addition, since the side edge of the liquid-permeable sheet is fixed to the liquid-impermeable sheet in the lower portion of the barrier cuff, urine does not diffuse further and side leakage can be prevented. Further, a shape-retaining elastic expansion / contraction member is provided at the fixed portion between the liquid-permeable sheet and the liquid-impermeable sheet, and a standing-up assisting elastic expansion / contraction member is provided adjacent to the outer side of the elastic expansion / contraction member. Regarding the standing up of the cuffs, since the elastic elastic member for standing up and the elastic elastic member for standing up support share the contracting force, the elastic elastic member for standing up directly contacting the skin gives the wearer a feeling of pressure and tightening. No more giving. In addition, the elastic elastic member for shape retention is used to bend the absorber into a boat shape, and the elastic elastic member for standing up lifts the entire barrier cuff upwards, so that the elastic for standing up that directly contacts the skin. The elastic member can easily follow the movement of the wearer. Furthermore, in addition to the blocking effect by the barrier cuffs, a high blocking effect can be expected because the weir is formed by the absorber and the side flaps.

以下、本考案を実施例に基づき詳説する。 図１において、本考案における紙おむつは、ポリエチレン等からなる不透液性 シート１と不織布などからなる透液性シート２との間に、綿状パルプ等からなる 、たとえば長方形若しくは砂時計形状のある程度剛性を有する吸収体３が介在さ れている。なお、吸収体３はその形状保持のために吸収紙（図示せず）により包 むことができる。不透液性シート１は吸収体３の周囲より外方に延在して砂時計 形状を成している。不透液性シート１の側方の延在部は、後述するバリヤーシー ト４および透液性シート２の側部とともに、フラップ部Ｆを形成する。前記バリ ヤーシート４の形成材料としては、プラスチックシートを使用することもできる が、肌の感触性の点で、不織布にシリコンなどにより撥水処理をしたものが好適 に用いられる。 前記透液性シート２は長方形をなし、脚回りでは吸収体３の側縁より若干外方 に延在し、不透液性シート１とホットメルト接着剤などにより固着されている。 Hereinafter, the present invention will be described in detail based on embodiments. In FIG. 1, a paper diaper according to the present invention comprises a liquid-impermeable sheet 1 made of polyethylene or the like and a liquid-permeable sheet 2 made of nonwoven fabric or the like, and made of cotton-like pulp or the like, for example, rectangular or hourglass-shaped rigidity. The absorber 3 having the above is interposed. The absorbent body 3 can be wrapped with absorbent paper (not shown) to maintain its shape. The liquid-impervious sheet 1 extends outward from the periphery of the absorbent body 3 and has an hourglass shape. The laterally extending portion of the liquid-impermeable sheet 1 forms a flap portion F together with a barrier sheet 4 and a side portion of the liquid-permeable sheet 2 which will be described later. As the material for forming the barrier sheet 4, a plastic sheet can be used, but from the viewpoint of the feel of the skin, a non-woven fabric treated with a water repellent material such as silicone is preferably used. The liquid-permeable sheet 2 has a rectangular shape, extends slightly outward from the side edge of the absorber 3 around the legs, and is fixed to the liquid-impermeable sheet 1 with a hot melt adhesive or the like.
【００１０】 長手方向端縁は紙おむつと一致している。また、腹側および背側の縁部には、不 透液性シート１と透液性シート２との間に発泡ウレタンなどからなる弾性伸縮バ ンドが介在されており、背側の両側部にはそれぞれ止着テープ６、６が固着され ている。The longitudinal edges coincide with the disposable diaper. Elastic elastic bands made of urethane foam or the like are interposed between the liquid-impermeable sheet 1 and the liquid-permeable sheet 2 at the edges on the ventral and dorsal sides. The fastening tapes 6 and 6 are fixed to each of them.
【００１１】 また、紙おむつの両側部には、使用面側に突出するバリヤーカフスＢ、Ｂが形 成されている。このバリヤーカフスＢは、図示のように、実質的に幅方向に連続 したバリヤーシート４と一本の弾性伸縮部材５または必要により複数本の弾性伸 縮部材とにより構成されている。さらに、バリヤーカフスＢは、バリヤーシート ４を内折りにされて二重に形成され、紙おむつ本体に拘束された二つの近位端、 すなわち内起立線５１および外起立線５２と自由の一つの遠位端６０とを有し、 バリヤーシート４の二重部分内に弾性伸縮部材５が配置され、外起立線５２はフ ラップ部Ｆにあり、内起立線５１は前記吸収体３の側縁の内方に位置している。Further, barrier cuffs B, B projecting toward the use surface side are formed on both sides of the disposable diaper. As shown in the figure, the barrier cuff B is composed of a barrier sheet 4 which is substantially continuous in the width direction and one elastic stretchable member 5 or, if necessary, a plurality of elastic stretchable members. Furthermore, the barrier cuff B is formed by folding the barrier sheet 4 inward to form a double layer, and has two proximal ends that are constrained by the main body of the diaper, that is, the inner standing line 51 and the outer standing line 52 and one free end. The elastic stretchable member 5 is disposed in the double portion of the barrier sheet 4, the outer upright line 52 is at the flap F, and the inner upright line 51 is at the side edge of the absorbent body 3. It is located inward.
【００１２】 より詳しく説明すると、バリヤーシート４の外側部分は、たとえば３本のガス ケットカフス用弾性伸縮部材７、７…を挟んで不透液性シート１にホットメルト 接着剤（図面上×印により図示している）などにより固着され、内側部分は吸収 体３の側縁より若干内側の箇所において透液性シート２にホットメルト接着剤な どにより固着され、これらの両固着部分の中間が自由部分となっている。この自 由部分において、紙おむつの未使用の展開状態（図２の仮想線で示す）で実質的 に内方に折り畳まれ、その折り畳み側縁部分に前記弾性伸縮部材５が内方された 状態でバリヤーシート４に固着されている。さらに、場合によっては、図３に示 されるように、バリヤーシート４の二重部分の途中において内側部分と外側部分 とがホットメルト接着剤による整形用固定線５３により相互に固定することもで きる。More specifically, the outer portion of the barrier sheet 4 is attached to the liquid-impervious sheet 1 by sandwiching, for example, three elastic elastic members 7, 7 ... The inner part is fixed to the liquid-permeable sheet 2 with a hot melt adhesive or the like at a position slightly inside the side edge of the absorbent body 3, and the middle of these two fixed parts is free. It is a part. In this free portion, the disposable diaper is substantially folded inward in an unfolded state (shown by the phantom line in FIG. 2), and the elastic stretchable member 5 is folded inward at the folded side edge portion. It is fixed to the barrier sheet 4. Further, in some cases, as shown in FIG. 3, the inner portion and the outer portion may be fixed to each other by a shaping fixing line 53 made of hot melt adhesive in the middle of the double portion of the barrier sheet 4. Wear.
【００１３】 前記弾性伸縮部材５の両端は図２のハッチングで示されるようにホットメルト 接着剤によりバリヤーシート４に固定され、この両端以外が脚回り部分はフリー とされている。また、実施例では弾性伸縮部材５の固定位置は、バリヤーシート ４の自由部分の中間位置とされている。 バリヤシート４の自由部分の前後端部分は、その前記折り畳み内面が、図２の ハッチングで示す部分において、ホットメルト接着剤などにより、透液性シート ２の上面に固着され、紙おむつ本体に拘束されている。したがって、この拘束部 分を除くバリヤーシート４の長手方向中間の自由部分は内側に傾斜して起立する ようになるとともに、着用時に前後方向に舟形となったときにおいて、弾性伸縮 部材５の収縮力により、図２の実線で示すように起立し、バリヤーカフスＢが生 成される。Both ends of the elastic expansion / contraction member 5 are fixed to the barrier sheet 4 by a hot-melt adhesive as shown by hatching in FIG. 2, and the leg parts other than the both ends are free. Further, in the embodiment, the fixed position of the elastic expansion / contraction member 5 is an intermediate position of the free portion of the barrier sheet 4. The front and rear end portions of the free portion of the barrier sheet 4 are fixed to the upper surface of the liquid permeable sheet 2 by a hot melt adhesive or the like at the portion where the folding inner surface is hatched in FIG. ing. Therefore, the free portion at the middle of the longitudinal direction of the barrier sheet 4 excluding this restraint portion is inclined inward and rises up, and the contraction force of the elastic expansion / contraction member 5 is reduced when it becomes a boat shape in the front-rear direction when worn. As a result, the barrier cuffs B stand upright as shown by the solid line in FIG. 2 and are formed.
【００１４】 このバリヤーカフスＢ、Ｂは、着用者の脚回りに当接し、そのバリヤーカフス Ｂ、Ｂと透液性シート２とで囲まれる空間は、上方開口のほぼ台形の空間であり 、尿または軟便の閉じ込め空間を形成する。この空間内に排尿されると、その尿 は透液性シート２を通過して吸収体３内に吸収されるとともに、軟便固形分につ いては、バリヤーカフスＢ、Ｂがバリヤー（障壁）になってその乗り越えが防止 される。仮に、バリヤーカフスＢ、Ｂを乗り越えて横方向に尿が漏れたとしても 、弾性伸縮部材７、７…によって形成されるガスケットカフスにより横漏れが防 止される。The barrier cuffs B and B contact around the legs of the wearer, and the space surrounded by the barrier cuffs B and B and the liquid permeable sheet 2 is a substantially trapezoidal space having an upper opening. Alternatively, a confinement space for loose feces is formed. When urine is excreted in this space, the urine passes through the liquid-permeable sheet 2 and is absorbed in the absorbent body 3. At the same time, for solid solids of the soft stool, the barrier cuffs B and B serve as barriers. It will be prevented from overcoming. Even if urine leaks laterally after getting over the barrier cuffs B, B, the lateral leakage is prevented by the gasket cuffs formed by the elastic expansion / contraction members 7, 7.
【００１５】 一方、吸収体３の舟形の成形およびその形状保持のために、吸収体３の側縁に 近接する位置であって、透液性シート２と不透液性シート１との間に介在され、 紙おむつの長手方向に沿って形状保持用弾性伸縮部材９が設けられている。この 部分に形状保持用弾性伸縮部材９を設けると、ある程度剛性のある吸収体３が舟 形に折り曲げられ、着用者の体にフィットした形状に保持される。形状保持用弾 性伸縮部材９の収縮力が吸収体３に対して有効的に作用するためには、形状保持 用弾性伸縮部材が吸収体３の側縁に近接していることが重要であるが、本実施例 のように、透液性シート２をバリヤーカフスＢの下方部分において不透液性シー ト１に対して固定する構造が、形状保持用弾性伸縮部材９を吸収体３の側面に近 接して固定するために有効である。吸収体３の側縁と透液性シート２の不透液性 シート１に対する固定開始位置との離間距離Ｓ0 は１０mm以下、特に５mm以下で あることが望ましい。また、形状保持用弾性伸縮部材９と吸収体３との離間距離 Ｓ1 は、１９mm以下、特に１０mm以下であることが望ましい。On the other hand, in order to form the absorber 3 into a boat shape and maintain its shape, it is located at a position close to the side edge of the absorber 3 and between the liquid-permeable sheet 2 and the liquid-impermeable sheet 1. An elastic elastic member 9 for holding the shape is provided so as to extend along the longitudinal direction of the disposable diaper. By providing the shape-retaining elastic expansion / contraction member 9 in this portion, the absorber 3 having a certain degree of rigidity is bent into a boat shape and is held in a shape that fits the wearer's body. In order that the contracting force of the shape-holding elastic stretchable member 9 effectively acts on the absorber 3, it is important that the shape-holding elastic stretchable member is close to the side edge of the absorber 3. However, the structure in which the liquid permeable sheet 2 is fixed to the liquid impermeable sheet 1 at the lower portion of the barrier cuff B as in the present embodiment is such that the shape-holding elastic stretchable member 9 is attached to the side surface of the absorbent body 3. It is effective for fixing close to. The separation distance S 0 between the side edge of the absorber 3 and the fixing start position of the liquid-permeable sheet 2 with respect to the liquid-impermeable sheet 1 is preferably 10 mm or less, particularly 5 mm or less. The distance S 1 between the shape-retaining elastic member 9 and the absorber 3 is preferably 19 mm or less, and more preferably 10 mm or less.
【００１６】 さらに、本考案における紙おむつは、前記形状保持用弾性伸縮部材９の外方側 に隣接して起立補助用弾性伸縮部材１０が設けられている。この起立補助用弾性 伸縮部材１０は、図４に示されるように、バリヤーカフスＢ全体を上方に持ち上 げるため、起立用弾性伸縮部材５の収縮力を大きくせずとも、バリヤーカフスＢ の起立を容易とする。したがって、前記起立用弾性伸縮部材５の収縮力を設定す るに際しては、着用者の脚回りを締め付け圧迫感を与えない範囲で決定され、残 りの必要収縮力は前記起立補助用弾性伸縮部材１０によって負担される。起立用 弾性伸縮部材５と起立補助用弾性伸縮部材１０との収縮力の分担比は概ね３：７ 〜５：５の比率が良好である。また、形状保持用弾性伸縮部材９と起立補助用弾 性伸縮部材１０の離間距離Ｓ2 は２〜１０mm、好ましくは３〜５mmの範囲が良好 とされる。なお、起立補助用弾性伸縮部材１０は直接着用者の肌と密着しない。Further, the paper diaper according to the present invention is provided with an elastic elastic member 10 for standing up assistance adjacent to the outer side of the elastic elastic member 9 for shape retention. As shown in FIG. 4, since the elastic elastic member 10 for standing up lifts the entire barrier cuff B upward, the elastic elastic member 5 for standing up does not increase the contraction force of the elastic cuff B for standing up. Make it easy to stand up. Therefore, when setting the contraction force of the elastic elastic member 5 for standing up, it is determined within a range that does not give a feeling of pressure when the wearer's legs are tightened, and the remaining necessary contractive force is the elastic elastic member for standing up assistance. Burdened by 10. The contraction force sharing ratio between the upright elastic elastic members 5 and the upright elastic elastic members 10 is preferably approximately 3: 7 to 5: 5. Further, the distance S 2 between the elastic elastic member 9 for holding the shape and the elastic elastic member 10 for assisting the standing is preferably in the range of 2 to 10 mm, preferably 3 to 5 mm. The elastic elastic member 10 for standing up assistance does not directly adhere to the skin of the wearer.
【００１７】 また、前記起立補助用弾性伸縮部材１０はバリヤーカフスＢ全体を持ち上げる 結果、バリヤーカフスＢの自由部分に余裕が生まれ、着用者の動きに追随し易く なるとともに、バリヤーカフスＢによる堰止め効果とともに、吸収体３とサイド フラップ部で、立ち上がりの高い堰を形成するため堰止め効果を向上させること ができる。Further, the elastic elastic member 10 for standing up lifts the entire barrier cuff B, and as a result, a free space is created in the free portion of the barrier cuff B, which makes it easier to follow the movement of the wearer and is also blocked by the barrier cuff B. In addition to the effect, since the weir having a high rising is formed by the absorber 3 and the side flap portion, the damming effect can be improved.
【００１８】[0018]
以上詳説のとおり、本考案によれば、バリヤーカフス先端部分に配設された弾 性伸縮部材による肌への圧迫・締付けを無くするとともに、肌への追随性を良好 とし、さらに堰止め効果の高い紙おむつとすることができる。 As described above in detail, according to the present invention, the elastic stretchable member disposed at the tip of the barrier cuff eliminates pressure and tightening on the skin, improves the conformability to the skin, and further improves the damming effect. Can be a high-priced diaper.
