以下、本発明を、その実施例に基づいて、図面を参照して説明する。   Hereinafter, the present invention will be described with reference to the drawings based on the embodiments.

図１、図２に示されるように、本発明の実施例１の吸収性物品６は、不織布等からなる透液性のトップシート１と、ポリシートのみ、ポリシートと不織布、あるいは、不織布のみから成るバックシート２との間に、綿状パルプ等の吸収体３を介在させた構造である。なお、本発明の対象となる紙おむつ型式は、テープ式紙おむつ、パンツ式紙おむつのいずれでも良く、かつ装着対象者も大人用、ベビー用のいずれでも良い。以下、吸収性物品６について詳述する。
吸収体３は、図１に示されるように、方形に成形されたものが使用されているが、着用状況に合わせて略砂時計形状のものも可能である。その幅寸法は股間部への当たりによって着用者にゴワ付き感を与えない寸法幅となっている。この吸収体３は、形状保持とトップシート１を透過した体液の拡散性向上のためにクレープ紙（図示せず）によって囲繞されている。 As shown in FIGS. 1 and 2, the absorbent article 6 of Example 1 of the present invention is a liquid-permeable top sheet 1 made of a nonwoven fabric or the like, only a polysheet, a polysheet and a nonwoven fabric, or only a nonwoven fabric. It is the structure which interposed absorbers 3, such as cotton-like pulp, between back sheets 2 which consist of. The paper diaper type that is the subject of the present invention may be either a tape-type paper diaper or a pants-type paper diaper, and the person to be worn may be for adults or for babies. Hereinafter, the absorbent article 6 will be described in detail.
As shown in FIG. 1, the absorbent body 3 is formed in a square shape, but may be a substantially hourglass shape according to the wearing situation. The width dimension is a dimension width that does not give the wearer a feeling of stickiness by hitting the crotch part. The absorbent body 3 is surrounded by crepe paper (not shown) in order to maintain the shape and improve the diffusibility of body fluid that has passed through the top sheet 1.

吸収体の表面側（肌当接面側）を覆うトップシート１としては、有孔または無孔の不織布や多孔性プラスチックシートなどが好適に用いられる。不織布を構成する素材繊維は、ポリエチレンまたはポリプロピレン等のオレフィン系、ポリエステル系、ポリアミド系等の合成繊維の他、レーヨンやキュプラ等の再生繊維、綿等の天然繊維とすることができ、スパンレース法、スパンボンド法、サーマルボンド法、メルトブローン法、ニードルパンチ法等の適宜の加工法によって得られた不織布を用いることができる。これらの加工法の内、スパンレース法は柔軟性、ドレープ性に富む点で優れ、サーマルボンド法は嵩高でソフトである点で優れている。トップシート１に多数の透孔を形成した場合には、尿などが速やかに吸収されるようになりドライタッチ性に優れたものとなる。 As the top sheet 1 covering the surface side (skin contact surface side) of the absorbent body, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. The material fibers that make up the nonwoven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the top sheet 1, urine and the like are quickly absorbed, and the dry touch properties are excellent.

バックシート２は、図２に示されるように、吸収体３の裏面側（非肌当接面側）を覆い、さらに両側部が吸収性物品６の表面側に巻き込まれ、立体ギャザー４の幅方向の途中の所定位置まで延在する。バックシート２の材質は、ポリエチレンまたはポリプロピレンなどのプラスチックシートなどが用いられるが、近年はムレ防止の点から透湿性を有するものが好適に用いられる。この遮水・透湿性シートは、たとえばポリエチレンやポリプロピレン等などのオレフィン樹脂中に無機充填材を溶融混練してシートを形成した後、一軸または二軸方向に延伸することにより得られる微多孔性シートであり、仮にシート厚が同じであれば無孔シートよりも剛性が低下するため、柔軟性の点で勝るものとなる。ポリシートのみ、ポリシートと不織布、あるいは、不織布から成るバックシート２の前端部１１および後端部１２では、吸収体３の存在しないエンドフラップ部１１ａ、１２ａが形成され、同様に両側部では吸収体３の存在しないサイドフラップ部１１ｂ、１２ｂが形成されている。 As shown in FIG. 2, the back sheet 2 covers the back surface side (non-skin contact surface side) of the absorbent body 3, and both side portions are wound around the front surface side of the absorbent article 6. It extends to a predetermined position in the middle of the direction. As the material of the back sheet 2, a plastic sheet such as polyethylene or polypropylene is used. In recent years, a material having moisture permeability is preferably used from the viewpoint of preventing stuffiness. This water barrier / moisture permeable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility. At the front end portion 11 and the rear end portion 12 of the back sheet 2 made of only a policy sheet, a polysheet and a nonwoven fabric, or a nonwoven fabric, end flap portions 11a and 12a where the absorbent body 3 does not exist are formed. Side flap portions 11b and 12b where the body 3 does not exist are formed.

本発明の実施例１の吸収性物品６の表面側両側部には、トップシート１の側部を覆うとともに、バックシート２の側縁を超えてバックシート２を覆うように所定の幅位置まで延在する立体ギャザー４が配設されている。すなわち、立体ギャザー４の内方側が二重に折り返され、この折返し部分に弾性伸縮部材８が配設され、内方側シート部分が弾性伸縮部材８の伸縮力を利用して表面側に起立するようになっている。この弾性伸縮部材８は、足回りの隙間を無くし漏れを無くすためのものである。
さらに、不織布５ａは立体ギャザー４を構成し、図２、図３ａに示されるようにポリマー等の吸収性物質５ｃが不織布５ａに水溶性のホットメルト接着剤等の水溶性接着剤５ｂで固着され、吸収性物質５ｃが固着された不織布５ａが立体ギャザー４内部に挿入され、立体ギャザー４の起立状態を保持し尿を確実に堰き止める。 図３ｂに示されるように不織布５ａは無く、立体ギャザー４自体が不織布から成り、ポリマー等の吸収性物質５ｃが立体ギャザー４に水溶性のホットメルト接着剤等の水溶性接着剤５ｂで固着される場合も有る。
さらに、吸収性物質５ｃが不織布５ａにホットメルト接着剤等の水溶性接着剤５ｂで固着されるため、図４に示されるように吸収性物質５ｃが立体ギャザー４内部で尿により流動化されつつ尿を十分確実に吸収する。 この水溶性接着剤５ｂは、体液との接触により接着力が弱まるような接着剤、例えば、ポリビニルアルコール、ポリアルキレンオキサイド等を主成分とする水分散型ホットメルト接着剤、あるいは、澱粉糊、カルボキシメチルセルロース等の水溶性接着剤から成る。
また、ポリマー等の吸収性物質５ｃは、尿により膨潤し、立体ギャザー４も膨らんで人体７にフィットし易くなる。 The both sides of the surface side of the absorbent article 6 of Example 1 of the present invention cover the side part of the top sheet 1 and up to a predetermined width position so as to cover the back sheet 2 beyond the side edge of the back sheet 2. An extending three-dimensional gather 4 is provided. That is, the inner side of the three-dimensional gather 4 is folded back twice, the elastic stretchable member 8 is disposed in the folded portion, and the inner sheet portion stands on the surface side using the stretchable force of the elastic stretchable member 8. It is like that. This elastic expansion / contraction member 8 is for eliminating gaps around the legs and eliminating leakage.
Further, the nonwoven fabric 5a constitutes a three-dimensional gather 4, and as shown in FIGS. 2 and 3a, an absorbent material 5c such as a polymer is fixed to the nonwoven fabric 5a with a water-soluble adhesive 5b such as a water-soluble hot melt adhesive. The non-woven fabric 5a to which the absorbent material 5c is fixed is inserted into the three-dimensional gather 4, and the three-dimensional gather 4 is kept upright and the urine is reliably dammed. As shown in FIG. 3b, there is no nonwoven fabric 5a, the solid gather 4 itself is made of a nonwoven fabric, and an absorbent material 5c such as a polymer is fixed to the solid gather 4 with a water-soluble adhesive 5b such as a water-soluble hot melt adhesive. There is also a case.
Further, since the absorbent material 5c is fixed to the nonwoven fabric 5a with a water-soluble adhesive 5b such as a hot melt adhesive, the absorbent material 5c is fluidized by urine inside the three-dimensional gather 4 as shown in FIG. Absorb urine sufficiently. This water-soluble adhesive 5b is an adhesive whose adhesive strength is weakened by contact with body fluids, for example, a water-dispersed hot melt adhesive mainly composed of polyvinyl alcohol, polyalkylene oxide, etc., starch starch, carboxy It consists of a water-soluble adhesive such as methylcellulose.
In addition, the absorbent material 5c such as a polymer swells with urine, and the three-dimensional gather 4 swells to easily fit the human body 7.

本発明は、失禁パッド、尿パッド等の吸収性物品であり、装着対象となるおむつ型式は、テープ式おむつ、パンツ式おむつのいずれでも良く、かつ装着対象者も大人用、ベビー用のいずれにも適用可能である。又、吸収性物品単独にても男性の排尿に供することも可能である。 The present invention is an absorbent article such as an incontinence pad, a urine pad, etc. The diaper model to be worn may be either a tape diaper or a pant diaper, and the wearer may be an adult or a baby. Is also applicable. In addition, the absorbent article alone can be used for male urination.
