Description

この考案は、おむつに関するものであって、詳しくは、ヒトからの***物がおむつ内部に放出された際に、おむつの股間部近傍から***物が漏洩するのを大幅に減少させることできるおむつに係る。   The present invention relates to a diaper, and more particularly, to a diaper that can greatly reduce the leakage of excrement from the vicinity of the crotch of the diaper when excrement from a human is released into the diaper. Related.

ヒトが着用するおむつは、吸収性物品とも呼ばれるが、そうしたおむつは、特別な止着手段を持たないパンツ型おむつと、テープ又はベルトなどの止着手段を備えた非パンツ型おむつとに大別することができる。そして、非パンツ型おむつは、これに用いている止着手段の違いによって、テープ型(外羽根式)おむつと、ベルト型((内羽根式)おむつとに分類することができる。   Diapers worn by humans are also called absorbent articles, but such diapers are roughly classified into pants-type diapers that do not have special fastening means and non-pants-type diapers that have fastening means such as tapes or belts. can do. And a non-pants type diaper can be classified into a tape type (outer wing type) diaper and a belt type ((inner wing type) diaper) according to the difference of the fastening means used for this.

非パンツ型おむつは、通常、その着用に介護者を必要とするのに対し、パンツ型おむつは、多くの場合、被着者自身で着用できる利点がある。タイプの如何を問わず、おむつの基本構造は、おむつ股間部の前後方向に、超吸水性ポリマーとパルプと吸水紙との混合物(これを吸収体コアと呼ぶ)を帯状に設置した構造にある。しかし、この構造だけではおむつ内部に放出された***物の外部への漏洩を充分に防止することができない。このため、現在実用に供されているおむつには、内部に放出された排出物がおむつの股間部近傍から簡単には漏洩しないような工夫が施されている。   Non-pants-type diapers usually require a caregiver to wear them, whereas pants-type diapers often have the advantage that they can be worn by the wearer. Regardless of the type, the basic structure of a diaper is a structure in which a mixture of superabsorbent polymer, pulp and water absorbent paper (this is called an absorbent core) is installed in a strip shape in the front-rear direction of the diaper crotch. . However, this structure alone cannot sufficiently prevent the excrement discharged into the diaper from leaking outside. For this reason, the diaper currently put into practical use is devised so that the discharge discharged inside does not easily leak from the vicinity of the crotch portion of the diaper.

例えば、非パンツ型おむつにあっては、その股間部対応部位の両縁に、弾性収縮性のガスケットカフスと、バリアカフスを設けることにより、***物が股間部近傍から漏洩するのを防止している(特公平6-93901号公報参照)。また、パンツ型おむつでは、その股間部内側の両側に防漏カフを設けると共に、腹部内側及び腰部内側に、それそれ防漏ポケットを付設することが提案されている(特開2003-10237号公報参照)   For example, in a non-pants-type diaper, excrement is prevented from leaking from the vicinity of the crotch part by providing an elastic shrinkable gasket cuff and a barrier cuff on both edges of the corresponding part of the crotch part. (See Japanese Patent Publication No. 6-93901). Further, in a pants-type diaper, it has been proposed to provide a leak-proof cuff on both sides inside the crotch part, and to attach a leak-proof pocket to each of the abdomen and waist areas (Japanese Patent Laid-Open No. 2003-10237) reference)

パンツ型であるか非パンツ型であるかを問わず、従来のおむつ股間部近傍に設けられた漏洩防止手段では、***物の漏洩を満足できる程度に防ぐことが難しい。特に、おむつ着用者が横臥している状態が比較的長時間続いた場合には、おむつ内部に蓄積された***物の量が少なくても、従来のおむつでは漏洩の心配がある。
この考案の目的は、おむつ股間部近傍から***物が漏洩する心配を払拭できるパンツ型おむつ及び非パンツ型おむつを提供することにある。
Regardless of whether it is a pants-type or a non-pants-type, it is difficult to prevent leakage of excrement to a satisfactory degree with the leakage preventing means provided in the vicinity of the diaper crotch part. In particular, when the diaper wearer is lying on the ground for a relatively long time, there is a risk of leakage in the conventional diaper even if the amount of excrement accumulated in the diaper is small.
An object of the present invention is to provide a pants-type diaper and a non-pants-type diaper that can eliminate the concern that excrement leaks from the vicinity of the diaper crotch.

この考案に係るパンツ型おむつは、短辺対長辺の長さに比が1:1.0〜1.5の範囲にある矩形シートの対向する2つの短辺又は長辺の中央部を、両側に前部残留辺及び後部残留辺を残して弓形に切り欠き、その辺に平行なシート中心線に関して対称な2つの湾入部を設け、湾入部を設けない2辺をそれぞれ立ち上げて向き合せ、両側で向き合う前部残留辺と後部残留辺を接合した形態のパンツ型形状にあり、1つのウエストホールと2つのレッグホールのそれぞれに近傍に細長い弾性材が配設されている外装パンツと、外装パンツの股間部内側中央部に、前記シート中心線に沿って接合された前後方向に伸びる吸収体とを備えたパンツ型おむつにおいて、吸収体と外装パンツの股間部との間の弾性材不存在領域に、超吸水性ポリマー層を付設したことを特徴とする。   The underpants type diaper according to the present invention has two short sides or a central part of the long sides facing each other in a rectangular sheet having a ratio of the short side to the long side in the range of 1: 1.0 to 1.5. Cut out in a bow shape, leaving the front and rear residual sides on both sides, and provide two bay entrances that are symmetric about the sheet center line parallel to the sides, and raise and face the two sides that do not have bay entrances. An exterior pant having a pant-type shape in which a front residual side and a rear residual side facing each other are joined, and an elongated elastic material is disposed in the vicinity of each of one waist hole and two leg holes, In a pant-type diaper comprising an absorbent body extending in the front-rear direction joined along the sheet center line at the inner central part of the crotch part of the exterior pants, there is no elastic material between the absorbent body and the crotch part of the exterior pants. Super absorbent polymer layer in the existing area And it said that it has set.

また、この考案に係る非パンツ型おむつは、短辺対長辺の長さの比が1:1.5〜3.5の範囲にある矩形シートの対向する2つの短辺又は長辺の中央部を、両側に前部残留辺と後部残留辺を残して弓形に切り欠き、その辺に平行なシート中心線に関して対称な2つの湾入部を設けた形状にあり、2つの湾入部の縁部近傍に細長い弾性材が前記シート中心線方向に配設されている外装シートと、前記湾入部が形成する外装シートの狭隘部分上面に、前後方向に配設された吸収体コアと、そのコアの上面全域を覆い、コア周縁部で外装シートに接合された液透過性シートと、前記外装シートの前部残留辺及び/又は後部残留辺に設けた止着手段とを備えたおむつにおいて、吸収体コアと外装シートの間の弾性材不存在領域に、超吸水性ポリマー層を付設したことを特徴とする。   Moreover, the non-pants-type diaper according to the present invention is the center of two opposing short sides or long sides of a rectangular sheet having a short side to long side length ratio of 1: 1.5 to 3.5. The part is cut out into an arc shape with the front and rear residual sides on both sides, and has two bay entrances symmetrical about the sheet center line parallel to the sides, and the edges of the two bay entrances An exterior sheet in which an elongated elastic material is disposed in the vicinity of the sheet center line, an absorber core disposed in the front-rear direction on the upper surface of the narrow portion of the exterior sheet formed by the bay portion, and the core In a diaper comprising a liquid-permeable sheet that covers the entire upper surface and is joined to an exterior sheet at the periphery of the core, and fastening means provided on the front remaining side and / or the rear remaining side of the exterior sheet. Superabsorbent polymer in the absence of elastic material between the core and the outer sheet Characterized in that it was attached to.

この考案に係るおむつは、従来のおむつに通常配設される吸収体コアに加えて、超吸水性ポリマー層を備えているため、従来のおむつに比較して、おむつ内に保持できる液量を大幅に増大させることができ、このために、おむつ着用者が横臥状態を長時間続けても、おむつ股間部近傍からの尿漏れなどを効果的に抑止することができる。   The diaper according to the present invention has a super absorbent polymer layer in addition to the absorber core that is usually disposed in the conventional diaper, so that the amount of liquid that can be held in the diaper is higher than that of the conventional diaper. For this reason, even if the diaper wearer keeps lying down for a long time, leakage of urine from the vicinity of the diaper crotch can be effectively suppressed.

本考案に係るおむつを添付図面に沿って説明すると、図1は、本考案に係るパンツ型おむつの一例を示す外観斜視図であり、図2はそのおむつを展開し、弾性体を緊張させた状態の下で、おむつ内面を示す平面図であり、図3は、図2のA−A線での断面図である。   The diaper according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is an external perspective view showing an example of a pants-type diaper according to the present invention, and FIG. 2 is an unfolded diaper to tension an elastic body. FIG. 3 is a plan view showing the inner surface of the diaper under the state, and FIG. 3 is a cross-sectional view taken along line AA of FIG.

図1〜図3において、外装パンツAは、矩形シートの対向する長辺の中央部を、両側に後部残留辺7,7と前部残留辺8,8を残して弓形に切り欠き、切り欠いた辺に平行なシート中心線に関して対称な2つの湾入部を設け、湾入部を設けていない対向2辺をそれぞれ立ち上げて向き合せ、向き合わせた辺の両側で前部残留辺と後部残留辺を接合することで形成される。この外装パンツAは、図1に示すとおり、一つのウエストホール3と二つのレッグホール4を持ち、ウエストホール近傍には、通常複数本の細長い弾性材が配設され、レッグホール近傍には、1本又はそれ以上の細長い弾性材が配設される。
外装パンツに配設されている複数本の細長い弾性材は、通常、外装パンツの外面や内面に露呈せず、従って、外装パンツの内面(着用者の肌に接する面を言う)を示す展開図には、弾性材は現れない。しかし、図2では便宜的にこれらの弾性材を2点鎖線で表示する。
1 to 3, the exterior pants A are cut out in a bow shape with the rear long sides 7 and 7 and the front remaining sides 8 and 8 left and left at the center of the opposing long sides of the rectangular sheet. Two bay entrances that are symmetric with respect to the sheet center line parallel to the side where the ridges are located are provided, the two opposite sides that are not provided with the bay entrances are raised and faced, and the front and rear residual sides on both sides of the facing sides. It is formed by joining. As shown in FIG. 1, the exterior pants A have one waist hole 3 and two leg holes 4, and usually a plurality of elongated elastic members are disposed in the vicinity of the waist hole, and in the vicinity of the leg hole, One or more elongated elastic members are disposed.
The plurality of elongate elastic members arranged in the exterior pants are not normally exposed on the outer surface or the inner surface of the exterior pants, and therefore show the inner surface of the exterior pants (referring to the surface in contact with the wearer's skin). In this case, no elastic material appears. However, in FIG. 2, these elastic materials are indicated by a two-dot chain line for convenience.

なお、図2に示す実施例では、矩形シートの長辺に湾入部を設けているが、湾入部を長辺に設ける代わりに、短辺に設けても差し支えない。この場合、外装パンツのウエストホールは、矩形シートの2つの長辺で形作られので、その近傍に配設される細長い弾性材は、長辺に平行に並ぶのが普通である。
外装パンツの形成に使用される矩形シートは、2枚の不織布シートの間に、複数本の細長い弾性材を挟んで不織布シートをラミネートしたものであることが好ましい。
In addition, in the Example shown in FIG. 2, although the bay insertion part is provided in the long side of a rectangular sheet, it may be provided in a short side instead of providing a bay insertion part in a long side. In this case, since the waist hole of the exterior pants is formed by the two long sides of the rectangular sheet, the elongated elastic members disposed in the vicinity thereof are usually arranged in parallel to the long sides.
The rectangular sheet used for forming the exterior pants is preferably a laminate of non-woven sheets sandwiched between two non-woven sheets with a plurality of elongated elastic materials.

外装パンツAの股間部内側の中央部には、上記したシート中心線に沿って吸収体5が配設される。吸収体5は、通常、綿状パルプと超吸水性ポリマーと吸水紙とで構成される全体として扁平な吸収体コア6を、液透過性表面シート7と液不透過性裏面シート8で挟み、吸収体コア周縁で両シートをヒートシールするか、ホットメルト接合して作成される(図3参照)。液透過性シートには、不織布や多数の孔を持つプラスチックフィルムが使用できる。   The absorbent body 5 is disposed along the above-described sheet center line in the central portion inside the crotch portion of the exterior pants A. The absorbent body 5 is generally sandwiched between a liquid-permeable top sheet 7 and a liquid-impermeable back sheet 8 with a generally flat absorbent core 6 composed of cotton-like pulp, super absorbent polymer and water-absorbing paper, The two sheets are heat-sealed at the periphery of the absorber core or hot melt bonded (see FIG. 3). As the liquid permeable sheet, a nonwoven fabric or a plastic film having a large number of holes can be used.

従来のパンツ型おむつでは、吸収体5が外装パンツの股間部内面に直接接合され、詳しく言えば、吸収体の裏面シート8がホットメルトによって外装パンツに接合されるが、本考案のパンツ型おむつでは、吸収体5と外装パンツ内面との間に、超吸水性ポリマー層9が付加的に設置される。   In the conventional pant-type diaper, the absorbent body 5 is directly joined to the inner surface of the crotch part of the exterior pants. Specifically, the back sheet 8 of the absorbent body is joined to the exterior pants by hot melt. Then, a super absorbent polymer layer 9 is additionally installed between the absorber 5 and the inner surface of the outer pants.

本考案での超吸水性ポリマー層9の平面形状は、台形、矩形など任意に選択することができ、その大きさも外装パンツに収まることを条件に、任意に選択できる。超吸水性ポリマー層9は、吸収体5の配設領域近傍に設置されるが、この場合、ポリマー層9と吸収体5とが、図2に示すように、重なっても差し支えない。しかし、ポリマー層9の設置個所は、外装パンツに配設されている細長い弾性材が存在しない外装パンツ内面であることが好ましい。ポリマー層9を弾性材存在領域に接合したのでは、弾性材の収縮性が損なわれるからである。ちなみに、図示の具体例では、外装パンツの股間部を横断して弾性材が配設されているので、図2に示す超吸水性ポリマー層9は、股間部の弾性材配設領域を跨いで、前後に二分されている。   The planar shape of the superabsorbent polymer layer 9 in the present invention can be arbitrarily selected such as a trapezoid and a rectangle, and the size thereof can be arbitrarily selected on the condition that it fits in the exterior pants. The super water-absorbing polymer layer 9 is installed in the vicinity of the region where the absorber 5 is disposed. In this case, the polymer layer 9 and the absorber 5 may overlap as shown in FIG. However, the installation location of the polymer layer 9 is preferably the inner surface of the outer pants without the elongated elastic material disposed in the outer pants. This is because, when the polymer layer 9 is bonded to the elastic material existence region, the contractibility of the elastic material is impaired. Incidentally, in the illustrated example, since the elastic material is disposed across the crotch portion of the exterior pants, the super absorbent polymer layer 9 shown in FIG. 2 straddles the elastic material disposition region of the crotch portion. , Has been divided into two parts.

超吸水性ポリマー層9には、当業界で公知である粒状の超吸水性樹脂又は高吸水性樹脂を、例えば、粒状ポリアクリル酸ソーダの集合体を層状にして不織布シートでサンドイッチにし、板状集合体の周縁で不織布シートをホットメルト接合したものを使用することが好ましい。
なお、図示を省略したが、本考案のパンツ型おむつには、前記したシート中心線を関して対称な2つの弾性収縮性の立体バリアカフスを、吸収体5を挟んで設置することができる。
For the superabsorbent polymer layer 9, a granular superabsorbent resin or a superabsorbent resin known in the art, for example, an aggregate of granular polyacrylic acid soda is layered and sandwiched with a non-woven sheet to form a plate shape It is preferable to use a non-woven sheet hot-melt bonded at the periphery of the aggregate.
Although not shown in the drawings, the elastic pants-type diaper of the present invention can be provided with two elastically shrinkable three-dimensional barrier cuffs that are symmetrical with respect to the sheet center line, with the absorbent body 5 interposed therebetween.

この考案に係る非パンツ型おむつの具体例は、図4〜図6に示される。図4は、テープ型おむつを展開し、弾性材を緊張させておむつ内面を示す平面図であり、図5は図4のB−B線での断面図である。図6はベルト型おむつを展開し。弾性材を緊張させておむつ内面を示す平面図である。ここで、内面とはおむつ着用者の肌に接する面を意味する。   Specific examples of the non-pants-type diaper according to the present invention are shown in FIGS. FIG. 4 is a plan view showing the inner surface of the diaper by developing the tape-type diaper and tensioning the elastic material, and FIG. 5 is a cross-sectional view taken along the line BB of FIG. Fig. 6 shows a belt-type diaper. It is a top view which shows the inner surface of a diaper by tensioning an elastic material. Here, the inner surface means a surface in contact with the skin of the diaper wearer.

図4及び図6に示すように、本考案に係るテープ型おむつB及びCは、矩形シートの対向する2つの長辺の中央部を、両側に後部残留辺1,1及び前部残留辺2,2を残して弓形に切り欠き、切り欠いた辺に平行なシート中心線に関して対称な湾入部を設けた形状にあり、2つの湾入部の縁部近傍に複数本の細長い弾性材を、前記のシート中心線に平行に配設されている外装シートを備え、さらに、後述するように、超吸水性ポリマー層9と、吸収体コア6を備えている。
また、外装シートに配設されている複数本の細長い弾性材は、前記したパンツ型おむつの場合と同様、おむつ内面を示す展開図には通常現れない。しかし、図4では便宜的にこれらの弾性材を2点鎖線で表示する。
As shown in FIGS. 4 and 6, the tape-type diapers B and C according to the present invention have a central portion of two opposing long sides of a rectangular sheet, a rear residual side 1, 1 and a front residual side 2 on both sides. , 2 is cut out into an arcuate shape, and a bay portion is provided that is symmetrical with respect to the sheet center line parallel to the cut-out side, and a plurality of elongated elastic members are provided in the vicinity of the edges of the two bay portions, The outer sheet is provided in parallel with the sheet center line, and further includes a superabsorbent polymer layer 9 and an absorbent core 6 as will be described later.
In addition, the plurality of elongated elastic members disposed on the exterior sheet does not usually appear in the developed view showing the inner surface of the diaper, as in the case of the above-described pants-type diaper. However, in FIG. 4, these elastic materials are indicated by a two-dot chain line for convenience.

図4に示すテープ型おむつBでは、外装シートの後部残留辺1,1に、それぞれテープ状の面ファスナー10が止着手段として直接取り付けられている。これに対し、図6に示すベルト型おむつCでは、外装シートの後部残留辺1,1に、それぞれベルト11を取り付け、一方のベルトの自由端に面ファスナー10を取り付けている。そして、ベルト型おむつCでは、外装シートの前部側短辺の適宜な個所に、面ファスナーが設けられている。   In the tape-type diaper B shown in FIG. 4, tape-shaped hook-and-loop fasteners 10 are directly attached to the rear remaining sides 1 and 1 of the exterior sheet, respectively, as fastening means. On the other hand, in the belt-type diaper C shown in FIG. 6, the belt 11 is attached to the rear remaining sides 1 and 1 of the exterior sheet, and the hook-and-loop fastener 10 is attached to the free end of one of the belts. In the belt-type diaper C, a hook-and-loop fastener is provided at an appropriate location on the front side short side of the exterior sheet.

おむつの外装シートを得るのに使用される矩形シートは、1枚のプラスチックフィルムを2枚の不織布シートで挟み、プラスチックフィルムと不織布シートとの間に、複数本の細長い弾性材を介在させてプラスチックフィルムと不織布シートを接合させたラミネートであることが好ましい。プラスチックフィルムとしては、ポリエチレンフィルムが使用され、不織布シートとしては、ポリオレフィン、ポリエステルなどの合成樹脂製の不織布シートが使用される。この種の不織布シートは、パンツ型オムツにも使用される。   The rectangular sheet used to obtain the outer packaging sheet of a diaper is a plastic sheet in which a single plastic film is sandwiched between two non-woven sheets, and a plurality of elongated elastic materials are interposed between the plastic film and the non-woven sheet. A laminate in which a film and a nonwoven fabric sheet are bonded is preferable. A polyethylene film is used as the plastic film, and a nonwoven fabric sheet made of a synthetic resin such as polyolefin or polyester is used as the nonwoven fabric sheet. This type of non-woven sheet is also used for pants-type diapers.

本考案の非パンツ型おむつでは、前記した吸収体5を使用する代わりに、表面シートと裏面シートでサンドイッチされていない吸収体コア6を、すなわち、綿状パルプと超吸水性ポリマーと吸収紙とからなる集合体を、超吸水性ポリマー層9と共に使用する。図4及び図6に示すように、吸収体コア6と超吸水性ポリマー層9とは、2つの湾入部が形成する外装シートの狭隘部分に、前記のシート中心線に沿って前後方向に延設される。そして、テープ型おむつBでも、ベルト型おむつCでも、吸収体コア6は、超吸水性ポリマー層9よりも内面側に位置する(図5参照)。   In the non-pants-type diaper of the present invention, instead of using the absorbent body 5 described above, an absorbent core 6 that is not sandwiched between a top sheet and a back sheet is used, that is, cotton-like pulp, superabsorbent polymer, and absorbent paper. The assembly consisting of is used with the superabsorbent polymer layer 9. As shown in FIGS. 4 and 6, the absorbent core 6 and the superabsorbent polymer layer 9 extend in the front-rear direction along the sheet center line in the narrow portion of the exterior sheet formed by the two baying portions. Established. In both the tape-type diaper B and the belt-type diaper C, the absorbent core 6 is located on the inner surface side of the superabsorbent polymer layer 9 (see FIG. 5).

本考案に係る非パンツ型おむつの外装シートに、2枚の不織布シートの間にプラスチックフィルムを挟んだラミネートを使用する場合には、図5に示す如く、前記ラミネートのプラスチックフィルムと、おむつ内面側不織布シートとの間に、吸収体コア6及び超吸水性ポリマー層9を挟持させることが好ましい。この態様では、吸収体コア6の上面が不織布シートで覆われることになるが、この不織布シートは、多数の孔が開いた孔明きプラスチックフィルムに置き換えることができる。
超吸水性ポリマー層9の平面形状は、台形、矩形など任意に選択することができる。しかし、ポリマー層9の設置個所は、外装シートに配設されている細長い弾性材が存在しない領域が選ばれる。
なお、図示を省略したが、本考案の非パンツ型おむつには、前記したシート中心線を関して対称な2つの弾性収縮性立体バリアカフスを、シート中心線を挟んでおむつの前後方向に設置することができる。
When a laminate in which a plastic film is sandwiched between two nonwoven fabric sheets is used for the exterior sheet of the non-pants diaper according to the present invention, as shown in FIG. 5, the laminated plastic film and the inner side of the diaper It is preferable to sandwich the absorbent core 6 and the superabsorbent polymer layer 9 between the nonwoven fabric sheets. In this aspect, the upper surface of the absorbent core 6 is covered with a nonwoven fabric sheet, but this nonwoven fabric sheet can be replaced with a perforated plastic film having a large number of holes.
The planar shape of the superabsorbent polymer layer 9 can be arbitrarily selected, such as a trapezoid and a rectangle. However, a region where the elongated elastic material disposed on the exterior sheet does not exist is selected as the installation location of the polymer layer 9.
Although not shown, in the non-pants diaper of the present invention, two elastic shrinkable three-dimensional barrier cuffs that are symmetric with respect to the seat centerline described above are installed in the front-rear direction of the diaper across the seat centerline. can do.
