本発明の使い捨ておむつは、外装部材の内側シートと外側シートが前側接着領域、中間接着領域、後側接着領域で互いに接着され、これらの接着領域で脚部弾性部材が内側シートおよび/または外側シートに接着固定される。そして、中間接着領域の前側端より前側かつ前側接着領域の前側端より後側に、前側非接着部が幅方向と前後方向に延びるように形成され、および/または、中間接着領域の後側端より後側かつ後側接着領域の後側端より前側に、後側非接着部が幅方向と前後方向に延びるように形成されることにより、外装部材の通気性を高めることができる。そのため、着用者から汗や蒸れなどが、前側非接着部や後側非接着部を通っておむつの外に好適に排出されやすくなる。   In the disposable diaper of the present invention, the inner sheet and the outer sheet of the exterior member are adhered to each other in the front adhesive region, the intermediate adhesive region, and the rear adhesive region, and the leg elastic members are the inner sheet and / or the outer sheet in these adhesive regions. It is fixed by adhesion. A front non-adhesive portion is formed so as to extend in the width direction and the front-rear direction on the front side of the front end of the intermediate adhesion region and on the rear side of the front end of the front adhesion region, and / or the rear end of the intermediate adhesion region. By forming the rear non-adhesive portion so as to extend in the width direction and the front-rear direction on the rear side and on the front side of the rear end of the rear adhesive region, the breathability of the exterior member can be enhanced. Therefore, sweat, stuffiness, and the like are easily discharged from the wearer to the outside of the diaper through the front non-adhesive portion and the rear non-adhesive portion.

前側脚部弾性部材と後側脚部弾性部材は、中間接着領域で股部を断続的に横断して設けられていることが好ましい。このように前側脚部弾性部材と後側脚部弾性部材が設けられれば、吸収性本体が前側脚部弾性部材と後側脚部弾性部材の収縮力によって歪みにくくなり、吸収性本体の着用者の股間でのフィット性を高めることができる。   The front leg elastic member and the rear leg elastic member are preferably provided so as to intermittently traverse the crotch portion in the intermediate bonding region. When the front leg elastic member and the rear leg elastic member are provided in this manner, the absorbent body is less likely to be distorted by the contracting force of the front leg elastic member and the rear leg elastic member, and the wearer of the absorbent body The fit between the crotch can be improved.

前後方向に延びる前側非接着部は、吸収性本体と重なって設けられている、および/または、前後方向に延びる後側非接着部は、吸収性本体と重なって設けられていることが好ましい。このように前側非接着部および/または後側非接着部が形成されることにより、おむつ内部に溜まった湿気がおむつの上方に排出されやすくなり、外装部材と吸収性本体が重なる部分での通気性を高めることができる。吸収性本体のバックシートが透湿性である場合は、吸収性本体に尿等が吸収された後、水分が湿気となって透湿性のバックシートを透過して前側非接着部および/または後側非接着部を通ることにより、おむつの外に好適に排出されやすくなる。   It is preferable that the front non-adhesive portion extending in the front-rear direction overlaps the absorbent main body, and / or the rear non-adhesive portion extending in the front-rear direction overlaps the absorbent main body. By forming the front non-adhesive portion and / or the rear non-adhesive portion in this manner, moisture accumulated inside the diaper is easily discharged to the upper side of the diaper, and ventilation is provided at a portion where the exterior member and the absorbent main body overlap. You can improve your sex. When the back sheet of the absorbent main body is moisture permeable, after the urine is absorbed by the absorbent main body, the moisture becomes moisture and permeates the moisture permeable back sheet, and the front non-adhesive part and / or the rear side. By passing through the non-adhesive part, it becomes easy to be suitably discharged to the outside of the diaper.

前側接着領域は吸収性本体と重なって設けられ、吸収性本体の前側端よりも前方に延在している、および/または、後側接着領域は吸収性本体と重なって設けられ、吸収性本体の後側端よりも後方に延在していることが好ましい。このように前側接着領域や後側接着領域が設けられていれば、吸収性本体の前後方向の端部が外装部材に対してずれにくくなり、おむつを着用した際に、吸収性本体が着用者の股間部で適切に位置決めされやすくなる。   The front adhesive region is provided so as to overlap with the absorbent main body, and extends forward of the front end of the absorbent main body, and / or the rear adhesive region is provided so as to overlap with the absorbent main body. It is preferable that it extends rearward from the rear side end. If the front adhesive region and the rear adhesive region are provided in this manner, the front and rear end portions of the absorbent main body are less likely to be displaced with respect to the exterior member, and when the diaper is worn, the absorbent main body is worn by the wearer. It becomes easier to be properly positioned in the crotch area.

前側胴部と後側胴部には、内側シートと外側シートの間に、幅方向に延びる胴部弾性部材が設けられ、前側接着領域および/または後側接着領域は胴部弾性部材から離間して設けられ、前側接着領域および/または後側接着領域と胴部弾性部材との間に、内側シートと外側シートが接着されない非接着部が形成されていることが好ましい。このように非接着部を設けることにより、外装部材の通気性をさらに高めることができる。   The front body and the rear body are provided with a body elastic member extending in the width direction between the inner sheet and the outer sheet, and the front adhesive region and / or the rear adhesive region is separated from the body elastic member. It is preferable that a non-adhesive portion in which the inner sheet and the outer sheet are not adhered is formed between the front elastic region and / or the rear elastic region and the body elastic member. By providing the non-adhesive portion in this manner, the air permeability of the exterior member can be further enhanced.

中間接着領域は、前側脚部弾性部材と後側脚部弾性部材の間で前後方向に断続的に設けられ、内側シートと外側シートとが接着されない中間非接着部が幅方向に延びるように形成されていることが好ましい。このように中間接着領域に中間非接着部を設けることにより、外装部材の股部での通気性を高めることができる。   The intermediate adhesive region is intermittently provided in the front-rear direction between the front leg elastic member and the rear leg elastic member, and is formed such that the intermediate non-adhesive portion where the inner sheet and the outer sheet are not adhered extends in the width direction. Is preferably provided. By providing the intermediate non-adhesive portion in the intermediate adhesive region in this manner, it is possible to enhance the air permeability at the crotch portion of the exterior member.

幅方向に延びる前側非接着部、幅方向に延びる後側非接着部、および幅方向に延びる中間非接着部は、2mm以上10mm以下の幅で形成されていることが好ましい。このように各接着部を設けることにより、外装部材の通気性を高めるとともに、前側脚部弾性部材と後側脚部弾性部材を内側シートおよび/または外側シートに安定して接着固定しやすくなる。   It is preferable that the front non-adhesive portion extending in the width direction, the rear non-adhesive portion extending in the width direction, and the intermediate non-adhesive portion extending in the width direction are formed with a width of 2 mm or more and 10 mm or less. By providing the respective adhesive portions in this manner, the air permeability of the exterior member is enhanced, and the front leg elastic members and the rear leg elastic members can be stably adhered and fixed to the inner sheet and / or the outer sheet.

前後方向に延びる前側非接着部、および前後方向に延びる後側非接着部は、15mm以上の幅で形成されていることが好ましい。このように前後方向に延びる前側非接着部と前後方向に延びる後側非接着部が形成されていれば、おむつ着用の際に、おむつ内部に溜まった湿気がこれらの各接着部を通しておむつの上方に排出されやすくなる。   The front non-adhesive portion extending in the front-rear direction and the rear non-adhesive portion extending in the front-rear direction are preferably formed with a width of 15 mm or more. When the front non-adhesive portion extending in the front-rear direction and the rear non-adhesive portion extending in the front-rear direction are formed in this manner, moisture accumulated inside the diaper passes through each of these adhering portions when the diaper is worn, and the moisture is accumulated above the diaper. It becomes easy to be discharged to.

吸収性本体の外面側は外装部材に部分的に接着され、吸収性本体が外装部材に接着されない吸収性本体非接着部が、前側非接着部および/または後側非接着部と重なって、前後方向に延びるように形成されていることが好ましい。吸収性本体非接着部が前側非接着部および/または後側非接着部と重なって設けられることにより、おむつ内部に溜まった湿気がおむつの外により排出されやすくなる。   The outer surface side of the absorbent main body is partially adhered to the exterior member, and the absorbent main body non-adhesive part in which the absorbent main body is not adhered to the exterior member overlaps the front non-adhesive part and / or the rear non-adhesive part, It is preferably formed so as to extend in the direction. Since the absorbent body non-adhesive portion is provided so as to overlap the front non-adhesive portion and / or the rear non-adhesive portion, the moisture accumulated inside the diaper is easily discharged to the outside of the diaper.

前側接着領域および/または後側接着領域は、中間接着領域よりも剛軟度が高いことが好ましい。これにより外装部材の股部が軟らかく形成され、使い捨ておむつの着用感を向上させることができる。   It is preferable that the front adhesive region and / or the rear adhesive region has higher bending resistance than the intermediate adhesive region. As a result, the crotch portion of the exterior member is softly formed, and the wearing feeling of the disposable diaper can be improved.

本発明の使い捨ておむつは、外装部材の内側シートと外側シートが前側接着領域、中間接着領域、後側接着領域で互いに接着され、中間接着領域の前側端より前側かつ前側接着領域の前側端より後側に、前側非接着部が幅方向と前後方向に延びるように形成され、および/または、中間接着領域の後側端より後側かつ後側接着領域の後側端より前側に、後側非接着部が幅方向と前後方向に延びるように形成されている。そのため、着用者から汗や蒸れなどが、前側非接着部や後側非接着部を通っておむつの外に好適に排出されやすくなり、外装部材の通気性を高めることができる。   The disposable diaper of the present invention, the inner sheet and the outer sheet of the exterior member are bonded to each other in the front adhesive region, the intermediate adhesive region, the rear adhesive region, the front side of the front end of the intermediate adhesive region and the front end of the front adhesive region. A front non-adhesive portion is formed on the side so as to extend in the width direction and the front-rear direction, and / or on the rear side of the rear end of the intermediate adhesive region and on the front side of the rear end of the rear adhesive region. The adhesive portion is formed so as to extend in the width direction and the front-back direction. Therefore, sweat, stuffiness, and the like from the wearer are likely to be suitably discharged to the outside of the diaper through the front non-adhesive portion and the rear non-adhesive portion, and the breathability of the exterior member can be enhanced.

外装部材2の股部Rには、吸収性本体7が設けられる。吸収性本体7は、トップシート8とバックシート9とこれらの間に配された吸収体10を有する(図3を参照)。トップシート8は、おむつを着用の際に着用者側に位置するシートであり、吸収体10の肌面側に配される。トップシート8は液透過性であることが好ましい。バックシート9は、おむつを着用の際に着用者とは反対側に位置するシートであり、吸収体10の外面側に配される。バックシート9は液不透過性であることが好ましい。着用者から排泄された尿等はトップシート8を透過して吸収体10により収容され、バックシート9は排泄物が外部へ漏れるのを防ぐ。   The crotch portion R of the exterior member 2 is provided with the absorbent main body 7. The absorbent main body 7 has a top sheet 8, a back sheet 9 and an absorber 10 arranged between them (see FIG. 3). The top sheet 8 is a sheet located on the wearer side when wearing the diaper, and is arranged on the skin surface side of the absorber 10. The topsheet 8 is preferably liquid permeable. The back sheet 9 is a sheet located on the side opposite to the wearer when the diaper is worn, and is arranged on the outer surface side of the absorbent body 10. The backsheet 9 is preferably liquid impermeable. Urine excreted from the wearer penetrates the top sheet 8 and is accommodated by the absorber 10, and the back sheet 9 prevents excrement from leaking to the outside.

液透過性のトップシートとしては、例えば、セルロース、レーヨン、コットン等の親水性繊維から形成された不織布や、ポリオレフィン(例えば、ポリプロピレン、ポリエチレン)、ポリエステル(例えば、PET)、ポリアミド(例えば、ナイロン)等の疎水性繊維から形成された不織布であって、疎水性繊維の表面が界面活性剤により親水化されたもの等を用いることができる。また、トップシートとして、織布、編布、有孔プラスチックフィルム等を用いてもよい。   Examples of the liquid-permeable top sheet include non-woven fabrics formed from hydrophilic fibers such as cellulose, rayon, and cotton, polyolefins (eg polypropylene, polyethylene), polyesters (eg PET), polyamides (eg nylon). It is possible to use a non-woven fabric formed from hydrophobic fibers such as those in which the surface of the hydrophobic fibers is hydrophilized with a surfactant. Further, as the top sheet, woven cloth, knitted cloth, perforated plastic film or the like may be used.

液不透過性のバックシートとしては、ポリオレフィン(例えば、ポリプロピレン、ポリエチレン)、ポリエステル(例えば、PET)、ポリアミド(例えば、ナイロン)等の疎水性繊維から形成された不織布や、プラスチックフィルム等を用いることができる。バックシートは2以上のシートの積層体から構成されていてもよく、例えば、不織布とプラスチックフィルムとの積層体を用いてもよい。この場合、積層体を構成する各シートは同じ大きさであっても異なる大きさであってもよい。バックシートは、液不透過性であって、かつ透湿性であってもよい。   As the liquid-impermeable backsheet, use a non-woven fabric formed of hydrophobic fibers such as polyolefin (eg polypropylene, polyethylene), polyester (eg PET), polyamide (eg nylon), or a plastic film. You can The backsheet may be composed of a laminate of two or more sheets, and for example, a laminate of a nonwoven fabric and a plastic film may be used. In this case, the sheets forming the laminate may have the same size or different sizes. The backsheet may be liquid impermeable and moisture permeable.

吸収体は、尿等の排泄物を吸収できる吸収性材料を含むものであれば特に限定されない。吸収体としては、例えば、吸収性材料を所定形状に成形した成形体を用いることができる。吸収体は、紙シート(例えば、ティッシュペーパーや薄葉紙)や液透過性不織布等の被覆シートで覆われてもよい。吸収性材料としては、例えば、パルプ繊維等の親水性繊維や、ポリアクリル酸系、ポリアスパラギン酸系、セルロース系、デンプン・アクリロニトリル系等の吸水性樹脂等が挙げられる。また、吸水性材料には、ポリエチレン、ポリプロピレン等のポリオレフィン繊維や、PET等のポリエステル繊維、ポリアミド繊維等の熱融着性繊維が含まれてもよい。これらの熱融着性繊維は、尿等との親和性を高めるために、界面活性剤等により親水化処理がされていてもよい。吸収性材料は、吸収容量を高める点から、少なくとも吸水性樹脂を含むことが好ましい。   The absorber is not particularly limited as long as it contains an absorbent material capable of absorbing excrement such as urine. As the absorbent body, for example, a molded body obtained by molding an absorbent material into a predetermined shape can be used. The absorber may be covered with a cover sheet such as a paper sheet (eg, tissue paper or tissue paper) or a liquid-permeable nonwoven fabric. Examples of the absorbent material include hydrophilic fibers such as pulp fibers, water-absorbent resins such as polyacrylic acid-based, polyaspartic acid-based, cellulose-based, starch-acrylonitrile-based and the like. Further, the water absorbent material may include polyolefin fibers such as polyethylene and polypropylene, and polyester fibers such as PET and heat fusible fibers such as polyamide fibers. These heat-fusible fibers may be hydrophilized with a surfactant or the like in order to enhance the affinity with urine and the like. The absorbent material preferably contains at least a water-absorbent resin from the viewpoint of increasing the absorption capacity.

吸収体は、不織布シート間に吸水性樹脂を有しパルプ繊維を有しないように構成された吸収シートを有するものであってもよい。このように構成された吸収シートは、不織布シート間に吸水性樹脂を有するため、高い吸収容量を実現できるとともに、不織布シート間にパルプ繊維を有しないため、嵩張らず薄型に形成することができる。   The absorbent body may have an absorbent sheet configured to have a water absorbent resin between non-woven fabric sheets and not pulp fibers. The absorbent sheet thus configured has a water absorbent resin between the non-woven fabric sheets, so that a high absorption capacity can be realized, and since it does not have pulp fibers between the non-woven fabric sheets, it can be formed thin without being bulky.

吸収体は、吸収性材料として吸水性繊維を用いたものであってもよい。この場合もまた、薄型に形成された吸収体とすることができる。吸水性繊維としては、プロトン化または塩形成したカルボキシル基を含有する繊維が挙げられる。例えば、アクリル繊維を加水分解して、アクリル繊維に含まれるニトリル基をカルボキシル基に変換することにより、吸水性繊維を得ることができる。このとき、吸水性繊維に含まれるカルボキシル基は、アルカリ金属塩またはアンモニア塩を形成していることが好ましい。また吸水性繊維は、親水性繊維をアクリル酸に浸漬し、繊維表面でアクリル酸を析出させることにより製造することができる。   The absorbent body may use water absorbent fibers as the absorbent material. In this case as well, the absorber can be made thin. Examples of the water-absorbent fiber include a fiber containing a protonated or salt-formed carboxyl group. For example, the water absorbent fiber can be obtained by hydrolyzing the acrylic fiber and converting the nitrile group contained in the acrylic fiber into a carboxyl group. At this time, it is preferable that the carboxyl group contained in the water absorbent fiber forms an alkali metal salt or an ammonia salt. The water-absorbent fiber can be produced by immersing the hydrophilic fiber in acrylic acid and precipitating the acrylic acid on the fiber surface.

吸収体10の形状(平面形状)は特に限定されない。吸収体10の形状としては、例えば、略長方形、砂時計形、ひょうたん形、羽子板形等が挙げられる。図面では、吸収体10は略長方形に形成されている。   The shape (planar shape) of the absorber 10 is not particularly limited. Examples of the shape of the absorber 10 include a substantially rectangular shape, an hourglass shape, a gourd shape, and a battledore shape. In the drawing, the absorber 10 is formed in a substantially rectangular shape.

吸収性本体7には、肌面側の幅方向xの両側に立ち上がりフラップ12が設けられることが好ましい(図2および図3を参照)。立ち上がりフラップ12を設けることにより、尿等の排泄物の横漏れを防ぐことができる。立ち上がりフラップ12が立ち上がった状態の上端部(着用者側の端部)には、起立用弾性部材13が設けられることが好ましい。起立用弾性部材13の収縮力により、立ち上がりフラップ12が起立しやすくなる。   The absorbent main body 7 is preferably provided with rising flaps 12 on both sides in the width direction x on the skin surface side (see FIGS. 2 and 3). By providing the rising flap 12, side leakage of excrement such as urine can be prevented. It is preferable that a rising elastic member 13 is provided at an upper end portion (end portion on the wearer side) of the rising flap 12 in a raised state. The contraction force of the upright elastic member 13 facilitates the upright flap 12 to be upright.

The absorbent body 7 is provided on the skin side of the inner sheet 5. The outer sheet 6 is provided so that the outer surface side thereof faces the outer side of the diaper. The inner sheet 5 and the outer sheet 6 are each configured to have a front body portion P, a rear body portion Q, and a crotch portion R. The inner sheet 5 and the outer sheet 6 may be liquid-permeable or liquid-impermeable, and sheet materials that can be used for the top sheet 8 and the back sheet 9 can be used. It is preferable that the inner sheet 5 and the outer sheet 6 have moisture permeability, and thereby the wearing feeling of the exterior member 2 can be improved.

上記説明したトップシート、バックシート、外側シート、内側シート等のシート材料として不織布を用いる場合、不織布としては、スパンボンド不織布、エアスルー不織布、ポイントボンド不織布、メルトブロー不織布、SMS不織布等を用いることが好ましく、これにより薄くて丈夫なシートを容易に得ることができる。   When a non-woven fabric is used as the sheet material for the above-described top sheet, back sheet, outer sheet, inner sheet, etc., it is preferable to use spunbonded non-woven fabric, air-through non-woven fabric, point-bonded non-woven fabric, melt blown non-woven fabric, SMS non-woven fabric or the like. As a result, a thin and durable sheet can be easily obtained.

外装部材2の通気性を高める点からは、幅方向xに延びる前側非接着部17が、外装部材2の股部Rを幅方向xに横切って、外装部材2の一方側の外縁から他方側の外縁まで延びるように設けられることが好ましい。すなわち、前側非接着部17は、外装部材2の一方側の外縁から他方側の外縁まで幅方向xにまっすぐ延びるように設けられることが好ましい。また、このような前側非接着部17が前後方向yの異なる位置に2以上設けられることがより好ましい。同様に、幅方向xに延びる後側非接着部18は、外装部材2の股部Rを幅方向xに横切って、外装部材2の一方側の外縁から他方側の外縁まで延びるように設けられることが好ましい。すなわち、後側非接着部18は、外装部材2の一方側の外縁から他方側の外縁まで幅方向xにまっすぐ延びるように設けられることが好ましい。また、このような後側非接着部18が前後方向yの異なる位置に2以上設けられることがより好ましい。なお、幅方向xに延びる前側非接着部17と幅方向xに延びる後側非接着部18は、股部Rのみに設けられることが好ましく、前側胴部Pや後側胴部Qには設けられないことが好ましい。   From the viewpoint of enhancing the air permeability of the exterior member 2, the front non-adhesive portion 17 extending in the width direction x traverses the crotch portion R of the exterior member 2 in the width direction x and extends from the outer edge of one side of the exterior member 2 to the other side. Is preferably provided so as to extend to the outer edge of the. That is, it is preferable that the front non-adhesive portion 17 is provided so as to extend straight in the width direction x from the outer edge on one side of the exterior member 2 to the outer edge on the other side. It is more preferable that two or more such front non-adhesive portions 17 are provided at different positions in the front-rear direction y. Similarly, the rear non-adhesive portion 18 extending in the width direction x is provided so as to extend across the crotch portion R of the exterior member 2 in the width direction x and extend from the outer edge on one side of the exterior member 2 to the outer edge on the other side. It is preferable. That is, it is preferable that the rear non-adhesive portion 18 be provided so as to extend straight in the width direction x from the outer edge on one side of the exterior member 2 to the outer edge on the other side. It is more preferable that two or more such rear non-adhesive portions 18 are provided at different positions in the front-rear direction y. The front non-adhesive portion 17 extending in the width direction x and the rear non-adhesive portion 18 extending in the width direction x are preferably provided only on the crotch portion R, and are provided on the front body portion P and the rear body portion Q. Preferably not.

幅方向xに延びる前側非接着部17は、吸収性本体7と重なって設けられることが好ましい。また、幅方向xに延びる後側非接着部18は、吸収性本体7と重なって設けられることが好ましい。使い捨ておむつ1は、外装部材2と吸収性本体7が重なる部分で特に通気性が悪くなるが、このように前側非接着部17および/または後側非接着部18が形成されることにより、外装部材2と吸収性本体7が重なる部分での通気性を高めることができる。また、吸収性本体7のバックシート9が透湿性である場合は、吸収性本体7に尿等が吸収された後、水分が湿気となって透湿性のバックシート9を透過して前側非接着部17または後側非接着部18を通ることにより、おむつの外に好適に排出されやすくなる。   The front non-adhesive portion 17 extending in the width direction x is preferably provided so as to overlap the absorbent main body 7. The rear non-adhesive portion 18 extending in the width direction x is preferably provided so as to overlap the absorbent main body 7. The disposable diaper 1 has particularly poor air permeability in the portion where the exterior member 2 and the absorbent main body 7 overlap. However, by forming the front non-adhesive portion 17 and / or the rear non-adhesive portion 18 in this manner, the exterior diaper 1 It is possible to improve the air permeability in the portion where the member 2 and the absorbent main body 7 overlap. When the back sheet 9 of the absorbent main body 7 is moisture permeable, after the urine or the like is absorbed by the absorbent main body 7, the moisture becomes moisture and permeates the moisture permeable back sheet 9 and is not bonded to the front side. By passing through the part 17 or the rear non-adhesive part 18, it becomes easy to be suitably discharged to the outside of the diaper.

前後方向yに延びる前側非接着部17は、前側接着領域14の全体を横切って設けられることが好ましい。すなわち、前側非接着部17は、前側接着領域14の全体を横切って前後方向yにまっすぐ延びるように設けられることが好ましい。前後方向yに延びる後側非接着部18は、後側接着領域15の全体を横切って設けられることが好ましい。すなわち、後側非接着部18は、後側接着領域15の全体を横切って前後方向yにまっすぐ延びるように設けられることが好ましい。これにより外装部材2の通気性をより高めることができる。   The front non-adhesion portion 17 extending in the front-rear direction y is preferably provided across the entire front adhesion region 14. That is, the front non-adhesive portion 17 is preferably provided so as to extend straight across the entire front adhesive region 14 in the front-rear direction y. The rear non-adhesive portion 18 extending in the front-rear direction y is preferably provided across the entire rear adhesive region 15. That is, it is preferable that the rear non-adhesive portion 18 is provided so as to extend straight across the rear adhesive region 15 in the front-rear direction y. Thereby, the air permeability of the exterior member 2 can be further enhanced.

前後方向yに延びる前側非接着部17は、吸収性本体7と重なって設けられることが好ましい。また、前後方向yに延びる後側非接着部18は、吸収性本体7と重なって設けられることが好ましい。このように前側非接着部17および/または後側非接着部18が形成されることにより、おむつ内部に溜まった湿気がおむつの上方に排出されやすくなり、外装部材2と吸収性本体7が重なる部分での通気性を高めることができる。また、吸収性本体7のバックシート9が透湿性である場合は、吸収性本体7に尿等が吸収された後、水分が湿気となって透湿性のバックシート9を透過して前側非接着部17または後側非接着部18を通ることにより、おむつの外に好適に排出されやすくなる。   The front non-adhesive portion 17 extending in the front-rear direction y is preferably provided so as to overlap the absorbent main body 7. Further, the rear non-adhesive portion 18 extending in the front-rear direction y is preferably provided so as to overlap the absorbent main body 7. By forming the front non-adhesive portion 17 and / or the rear non-adhesive portion 18 in this way, moisture accumulated inside the diaper is easily discharged to the upper side of the diaper, and the exterior member 2 and the absorbent main body 7 overlap each other. The breathability in the part can be improved. When the back sheet 9 of the absorbent main body 7 is moisture permeable, after the urine or the like is absorbed by the absorbent main body 7, the moisture becomes moisture and permeates the moisture permeable back sheet 9 and is not bonded to the front side. By passing through the part 17 or the rear non-adhesive part 18, it becomes easy to be suitably discharged to the outside of the diaper.

前後方向yに延びる前側非接着部17と前後方向yに延びる後側非接着部18が吸収性本体7と重なる部分において、前後方向yに延びる前側非接着部17の幅方向xの長さ(複数ある場合はその合計長さ)と前後方向yに延びる後側非接着部18の幅方向xの長さ(複数ある場合はその合計長さ)は、吸収性本体7の幅方向xの長さの10%以上となることが好ましく、15%以上がより好ましい。これにより、外装部材2の通気性を高めやすくなる。一方、おむつを着用した際に、吸収性本体7が外装部材2に対してずれにくくする点から、前後方向yに延びる前側非接着部17と前後方向yに延びる後側非接着部18が吸収性本体7と重なる部分において、前後方向yに延びる前側非接着部17の幅方向xの長さと前後方向yに延びる後側非接着部18の幅方向xの長さは、吸収性本体7の幅方向xの長さの80%以下が好ましく、70%以下がより好ましい。   In a portion where the front non-adhesive portion 17 extending in the front-rear direction y and the rear non-adhesive portion 18 extending in the front-rear direction y overlap the absorbent body 7, the length in the width direction x of the front non-adhesive portion 17 extending in the front-rear direction y ( The total length of the absorbent main body 7) and the length of the rear non-adhesive portion 18 extending in the front-rear direction y in the width direction x (the total length of the absorbent main body 7 is the length of the absorbent main body 7 in the width direction x). It is preferably 10% or more, and more preferably 15% or more. This facilitates enhancing the air permeability of the exterior member 2. On the other hand, when the diaper is worn, the absorbent main body 7 is less likely to be displaced with respect to the exterior member 2, so that the front non-adhesive portion 17 extending in the front-rear direction y and the rear non-adhesive portion 18 extending in the front-rear direction y are absorbed. The length of the front non-adhesive portion 17 extending in the front-rear direction y in the width direction x and the length of the rear non-adhesive portion 18 extending in the front-rear direction y in the width direction x are the same as those of the absorbent main body 7. 80% or less of the length in the width direction x is preferable, and 70% or less is more preferable.

前後方向yに延びる前側非接着部17の幅方向xの長さ(複数ある場合はその合計長さ)と前後方向yに延びる後側非接着部18の幅方向xの長さ(複数ある場合はその合計長さ)は、互いに同じであっても異なっていてもよいが、前後方向yに延びる前側非接着部17の幅方向xの長さの方が前後方向yに延びる後側非接着部18の幅方向xの長さよりも長いことが好ましい。これにより、より多くの尿が溜まりやすいおむつの前側での通気性を高めることができる。   The length in the width direction x of the front non-adhesive portion 17 extending in the front-rear direction y (the total length when there are a plurality) and the length in the width direction x of the rear non-adhesion portion 18 extending in the front-rear direction y (there are a plurality). Their total length) may be the same as or different from each other, but the length in the width direction x of the front non-adhesive portion 17 extending in the front-rear direction y extends in the front-rear direction y. It is preferably longer than the length of the portion 18 in the width direction x. This can enhance the air permeability on the front side of the diaper where more urine is likely to accumulate.

前後方向yに延びる前側非接着部17は、前側脚部弾性部材22Fと重なって設けられないことが好ましい。前後方向yに延びる後側非接着部18は、後側脚部弾性部材22Bと重なって設けられないことが好ましい。このように前側非接着部17と後側非接着部18を設けることにより、前側脚部弾性部材22Fまたは後側脚部弾性部材22Bが前側接着領域14または後側接着領域15により好適に接着固定され、着用者の脚周りに沿ったレッグギャザーが好適に形成されやすくなる。   The front non-adhesive portion 17 extending in the front-rear direction y is preferably not provided so as to overlap the front leg elastic member 22F. The rear non-adhesive portion 18 extending in the front-rear direction y is preferably not provided so as to overlap the rear leg elastic member 22B. By providing the front non-adhesive portion 17 and the rear non-adhesive portion 18 in this manner, the front leg elastic member 22F or the rear leg elastic member 22B is more favorably adhered and fixed to the front adhesive region 14 or the rear adhesive region 15. As a result, leg gathers along the wearer's legs can be easily formed.

前側接着領域14は少なくとも一部が吸収性本体7と重なって設けられ、吸収性本体7の前側端よりも前方に延在して設けられることが好ましい。また、後側接着領域15は少なくとも一部が吸収性本体7と重なって設けられ、吸収性本体7の後側端よりも後方に延在して設けられることが好ましい。このように前側接着領域14や後側接着領域15が設けられていれば、吸収性本体7の前後方向yの端部が外装部材2(特に外側シート6)に対してずれにくくなり、おむつを着用した際に、吸収性本体7が着用者の股間部で適切に位置決めされやすくなる。   It is preferable that at least a part of the front adhesive region 14 overlaps the absorbent main body 7 and that the front adhesive region 14 extends forward of the front end of the absorbent main body 7. Further, it is preferable that at least a part of the rear side adhesive region 15 is provided so as to overlap with the absorbent main body 7, and the rear side adhesive region 15 is provided to extend rearward of the rear side end of the absorbent main body 7. If the front adhesive region 14 and the rear adhesive region 15 are provided in this manner, the end portion of the absorbent main body 7 in the front-rear direction y is less likely to be displaced with respect to the exterior member 2 (particularly the outer sheet 6), and the diaper When worn, the absorbent body 7 is likely to be properly positioned in the crotch of the wearer.

前側非接着部17と後側非接着部18の各幅は特に限定されないが、前後方向yに延びる前側非接着部17の幅が幅方向xに延びる前側非接着部17の幅よりも広いことが好ましく、前後方向yに延びる後側非接着部18の幅が幅方向xに延びる後側非接着部18の幅よりも広いことが好ましい。これにより、おむつ着用の際に、おむつ内部に溜まった湿気が、前後方向yに延びる前側非接着部17または前後方向yに延びる後側非接着部18を通しておむつの上方に排出されやすくなる。   The widths of the front non-adhesive portion 17 and the rear non-adhesive portion 18 are not particularly limited, but the width of the front non-adhesive portion 17 extending in the front-rear direction y is wider than the width of the front non-adhesive portion 17 extending in the width direction x. Preferably, the width of the rear non-adhesive portion 18 extending in the front-rear direction y is wider than the width of the rear non-adhesive portion 18 extending in the width direction x. Thereby, when the diaper is worn, the moisture accumulated inside the diaper is easily discharged above the diaper through the front non-adhesive portion 17 extending in the front-rear direction y or the rear non-adhesive portion 18 extending in the front-rear direction y.

幅方向xに延びる前側非接着部17および幅方向xに延びる後側非接着部18は、2mm以上10mm以下の幅で形成されていることが好ましい。当該幅は、3mm以上がより好ましく、4mm以上がさらに好ましく、また8mm以下がより好ましく、7mm以下がさらに好ましい。幅方向xに延びる前側非接着部17の幅と幅方向xに延びる後側非接着部18の幅を2mm以上とすることで、外装部材2の通気性を高めやすくなる。一方、当該幅を10mm以下とすることで、前側脚部弾性部材22Fまたは後側脚部弾性部材22Bが前側接着領域14または後側接着領域15により好適に内側シート5および/または外側シート6に接着固定され、着用者の脚周りに沿ったレッグギャザーが好適に形成されやすくなる。   The front non-adhesive portion 17 extending in the width direction x and the rear non-adhesive portion 18 extending in the width direction x are preferably formed with a width of 2 mm or more and 10 mm or less. The width is more preferably 3 mm or more, further preferably 4 mm or more, more preferably 8 mm or less, and further preferably 7 mm or less. By setting the width of the front non-adhesive portion 17 extending in the width direction x and the width of the rear non-adhesive portion 18 extending in the width direction x to be 2 mm or more, the air permeability of the exterior member 2 can be easily enhanced. On the other hand, by setting the width to 10 mm or less, the front leg elastic member 22F or the rear leg elastic member 22B is more preferably attached to the inner sheet 5 and / or the outer sheet 6 by the front adhesive region 14 or the rear adhesive region 15. Adhesion is fixed, and leg gathers along the wearer's legs are easily formed.

前後方向yに延びる前側非接着部17および前後方向yに延びる後側非接着部18は、15mm以上の幅で形成されていることが好ましく、20mm以上がより好ましく、25mm以上がさらに好ましい。このように前後方向yに延びる前側非接着部17と前後方向yに延びる後側非接着部18が形成されていれば、おむつ着用の際に、おむつ内部に溜まった湿気が前後方向yに延びる前側非接着部17または前後方向yに延びる後側非接着部18を通しておむつの上方に排出されやすくなる。前後方向yに延びる前側非接着部17と前後方向yに延びる後側非接着部18の幅の上限は特に限定されないが、150mm以下が好ましく、120mm以下がより好ましく、100mm以下がさらに好ましい。   The front non-adhesive portion 17 extending in the front-rear direction y and the rear non-adhesive portion 18 extending in the front-rear direction y are preferably formed with a width of 15 mm or more, more preferably 20 mm or more, and further preferably 25 mm or more.
