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には本発明の実施例１が示され、図１、図２に示す吸収性物品６は、不織布等からなる透液性のトップシート１と、ポリエチレン等から成るバックシート２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。
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、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。 1 and FIG. 2 show Example 1 of the present invention. The absorbent article 6 shown in FIGS. 1 and 2 includes a liquid-permeable top sheet 1 made of nonwoven fabric and the like, and a back sheet 2 made of polyethylene and the like. Between the two, an absorbent body 3 such as cotton pulp is interposed.
As shown in FIG. 1, the absorbent body 3 is formed in a rectangular shape, and 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. ing.

吸収体３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 3, a porous or non-porous nonwoven fabric, a porous plastic sheet, or the like 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.

ポリシートのみ、ポリシートと不織布、あるいは、不織布のみからなるバックシート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の前端部および後端部では、吸収体３の存在しないエンドフラップ部が形成され、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が形成されている。 As shown in FIG. 2, the back sheet 2 made of only the policy, the poly sheet and the non-woven fabric, or only the non-woven fabric covers the back side (non-skin contact surface side) of the absorbent body 3 and further absorbs both sides. It is wound on the surface side of the property article 6 and extends to a predetermined position in the width direction of the three-dimensional gather 4. 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 and the rear end of the back sheet 2 made of only the policy sheet, the polysheet and the nonwoven fabric, or the nonwoven fabric, the end flap portion where the absorber 3 does not exist is formed, and similarly, the absorber 3 does not exist on both sides. Side flaps are formed.

次に、吸収体３の長手方向両側部の上方において長手方向に沿ってトップシート１とバックシート２とが、例えば、接着剤５で接合されることにより吸収体３の長手方向両側部に長手方向に沿って吸収体３の存在しない空間部７ａ、７ｂが形成される。吸収体３の幅方向の寸法は、空間部７ａ、７ｂの幅寸法とから相対的に決められる。空間部７ａ、７ｂには消臭剤８が配置され、吸収体３より溢流した尿が薬液上を通過することで全体に薬液の効果が拡散して消臭効果を高める。
接着剤５は、好適にはホットメルト接着剤等の接合手段が用いられる。又、消臭剤８としては、粉体、薬液含浸部材、マイクロカプセル等であるが、特に人体（肌）に触れて異常を生じないことが必要である。例えば、複合コアセルベーション法によるマイクロカプセル化は、ゼラチン−アラビアゴムの系が用いられ、マイクロカプセルの芯（コア）となる分散粒子が互いに凝集し、全表面積が減少すると表面エネルギーは低下するのでコアセルベートと芯物質の親和性（濡れ）が良いことが重要であり、分散状態を維持する適当な攪拌が必要となる。 コアセルベーションの系に寄与する物質が単一であるか複数存在するかで、単純コアセルベーションと複合コアセルベーションに分類される。
以上により、空間部７ａ、７ｂと上述したバックシート２の巻き込み構造を組み合せることにより、大量の尿を装着される図示されない紙おむつ外部へ漏らさず、拡散させることができる。
このため、吸収体３から溢れた尿が拡散して消臭効果を高める。 Next, the top sheet 1 and the back sheet 2 are bonded to each other in the longitudinal direction of the absorbent body 3 by, for example, bonding the adhesive 5 with the top sheet 1 and the back sheet 2 along the longitudinal direction above the both sides of the absorbent body 3 in the longitudinal direction. Spaces 7a and 7b in which the absorber 3 does not exist are formed along the direction. The dimension in the width direction of the absorber 3 is relatively determined from the width dimension of the space portions 7a and 7b. A deodorant 8 is disposed in the space portions 7a and 7b, and the urine overflowing from the absorber 3 passes over the chemical solution, so that the effect of the chemical solution is diffused throughout and the deodorizing effect is enhanced.
As the adhesive 5, a joining means such as a hot melt adhesive is preferably used. The deodorant 8 is a powder, a chemical solution impregnated member, a microcapsule, or the like, and it is particularly necessary that the human body (skin) does not touch the body and cause an abnormality. For example, microencapsulation by the complex coacervation method uses a gelatin-gum arabic system, and the dispersed particles that form the core of the microcapsule aggregate together, and the surface energy decreases as the total surface area decreases. It is important that the affinity (wetting) between the coacervate and the core substance is good, and appropriate stirring to maintain the dispersed state is required. It is classified into simple coacervation and complex coacervation depending on whether a single substance or a plurality of substances contribute to the coacervation system.
As described above, by combining the space portions 7a and 7b and the above-described winding structure of the back sheet 2, a large amount of urine can be diffused without leaking to the outside of a paper diaper (not shown).
For this reason, the urine overflowing from the absorber 3 is diffused to enhance the deodorizing effect.

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が配設され、内方側シート部分が弾性伸縮部材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。
このため、尿、便等の漏れを防止し、かつ装着感に優れる。 On both sides of the surface side of the absorbent article 6 of Example 1 of the present invention, the side portion of the top sheet 1 is covered and the back sheet 2 is covered beyond the side edge of the back sheet 2 up to a predetermined width position. An extending three-dimensional gather 4 is provided. That is, the inner side of the three-dimensional gather 4 is folded back twice, an elastic stretchable member is disposed at the folded portion, and the inner sheet portion stands on the surface side using the stretchable force of the elastic stretchable member. It has become. This elastic expansion / contraction member is for eliminating gaps around the legs and eliminating leakage.
For this reason, leakage of urine, feces and the like is prevented, and the wearing feeling is excellent.

本発明の図示されない実施例としては、図１、図２ａ，図２ｂに示される実施例１のバックシート２の巻き込み構造及び先端部に配設される立体ギャザー４を有しない構成で、吸収性物品６の表面側両側部において、トップシート１とバックシート２の間に空間部７ａ、７ｂが形成されるに足る幅方向の寸法を有する吸収体３がトップシート１とバックシート２の間に配設され、長手方向両側部のトップシート１とバックシート２は接着剤５により接合される。空間部７ａ、７ｂ内には消臭剤８が挿入され、吸収体３より溢流した尿が薬液上を通過することで全体に薬液の効果が拡散して消臭効果を高める。
このため、吸収体３から溢れた尿が拡散して消臭効果を高める。 As an embodiment (not shown) of the present invention, the structure does not include the entrainment structure of the back sheet 2 of Embodiment 1 shown in FIGS. The absorbent body 3 having a dimension in the width direction sufficient to form the space portions 7 a and 7 b between the top sheet 1 and the back sheet 2 is formed between the top sheet 1 and the back sheet 2 on both sides on the surface side of the article 6. The top sheet 1 and the back sheet 2 on both sides in the longitudinal direction are joined by an adhesive 5. The deodorant 8 is inserted into the spaces 7a and 7b, and the urine overflowing from the absorber 3 passes over the chemical solution, so that the effect of the chemical solution is diffused throughout and the deodorizing effect is enhanced.
For this reason, the urine overflowing from the absorber 3 diffuses to enhance the deodorizing effect.

次に、本発明の実施例２が図３に示され、吸収体３から溢れた尿が空間部７ａ，７ｂに導かれるようにトップシート１にエンボス加工１ａが施される。
このため、吸収体３から溢れた尿を拡散してその結果、尿、便等の漏れを防止し、かつ装着感に優れる。 Next, Example 2 of the present invention is shown in FIG. 3, and the embossing 1a is applied to the top sheet 1 so that the urine overflowing from the absorber 3 is guided to the spaces 7a and 7b.
For this reason, the urine overflowing from the absorber 3 is diffused, and as a result, leakage of urine, feces, etc. is prevented and the wearing feeling is excellent.

本発明は、失禁パッド、尿パッド等の吸収性物品であり、吸収体より溢流した尿を拡散させ消臭効果を高める効果を奏し、特に多量の排尿時等の用途に適する。 The present invention is an absorbent article such as an incontinence pad or a urine pad, which has an effect of increasing the deodorizing effect by diffusing urine overflowing from the absorbent body, and is particularly suitable for a large amount of urination.
