Description

本発明は、吸収性物品に関する。 The present invention relates to an absorbent article.

尿の臭気を抑制するための消臭剤を備える吸収性物品が知られている。例えば、特許文献１は、消臭剤を備える吸収性物品が開示されている。この吸収性物品は、排尿後における雑菌の繁殖や強いアンモニア臭の発生を抑制するために、茶葉を含み、抗菌・脱臭性能を有する吸収シートを備えている。 Absorbent articles equipped with a deodorant to suppress urine odor are known. For example, Patent Document 1 discloses an absorbent article equipped with a deodorant. This absorbent article is equipped with an absorbent sheet that contains tea leaves and has antibacterial and deodorant properties to suppress the proliferation of bacteria and the generation of a strong ammonia odor after urination.

この吸収性物品では、吸収性物品を表面シート側から見て、茶葉を含む吸収シートによる有色領域を、吸収体による白色領域を囲む枠状に配置している。それにより、表面シートを透かして、吸収シートによる有色領域が窓枠状に視認され、有色領域の平面中央に、吸収体による白色領域が視認される。そのため、排尿後、白色領域に浸み込んだ（吸収された）尿の色を視ることにより、吸収性物品の使用者の健康状態などを確認することが可能とされる。 In this absorbent article, when viewed from the top sheet side, the colored area of the absorbent sheet containing tea leaves is arranged in a frame shape surrounding the white area of the absorbent body. This allows the colored area of the absorbent sheet to be seen like a window frame through the top sheet, and the white area of the absorbent body to be seen in the center of the plane of the colored area. Therefore, after urination, it is possible to check the health condition of the user of the absorbent article by viewing the color of the urine that has soaked into (absorbed into) the white area.

特開２０１６－１４６９８６号公報JP 2016-146986 A

吸収性物品の使用者による尿の***時に、吸収性物品が適切な位置に装着されていないと、***された尿が吸収体の外側に漏れ出る状況、すなわち尿漏れが生じ得る。尿漏れが生じ易い主な場所としては、吸収体における幅方向や長手方向の両端部が挙げられる。使用者又は介護者は、尿漏れが生じた場所を確認することで、吸収性物品の装着の状態を把握し、尿漏れの原因を特定して、尿漏れの再発の抑制に役立てている。また、そのときの尿の色を確認することで、使用者の健康状態を把握している。 If the absorbent article is not worn in an appropriate position when a user of the absorbent article excretes urine, the excreted urine may leak outside the absorbent body, i.e., urinary leakage may occur. The main areas where urinary leakage is likely to occur include both ends in the width direction and length direction of the absorbent body. By checking the area where urinary leakage occurred, the user or caregiver can understand the state of the absorbent article being worn, identify the cause of urinary leakage, and use this information to help prevent urinary leakage from recurring. In addition, by checking the color of the urine at that time, the user's health condition can be understood.

特許文献１の吸収性物品は、茶葉を含む消臭剤を含む吸収シートを備えているので、尿の臭気を抑制できる。しかし、この吸収性物品では、吸収体の白色領域を枠状に囲むように、吸収シートの有色領域が配置されている。そのため、尿漏れが生じ易い吸収体の幅方向や長手方向の両端部が有色領域により覆われていて、尿が見え難くなっている。したがって、使用者又は介護者は、尿漏れが生じた場所を正確に確認し難くなるおそれがある。そうなると、使用者又は介護者は、吸収性物品の装着の状態を適切に把握し難くなり、尿漏れの原因を特定し難くなる。また、茶殻は尿の色に近いため、茶殻上の尿の色を、本来の尿の色と誤認するなど、尿の色を正確に確認し難くなるおそれがある。そうなると、使用者又は介護者は、使用者の健康状態を適切に把握し難くなる。 The absorbent article of Patent Document 1 is provided with an absorbent sheet containing a deodorant containing tea leaves, so that it can suppress the odor of urine. However, in this absorbent article, the colored area of the absorbent sheet is arranged so as to surround the white area of the absorbent body in a frame shape. Therefore, both ends of the absorbent body in the width direction and length direction, where urine leakage is likely to occur, are covered by the colored area, making the urine difficult to see. Therefore, it may be difficult for the user or caregiver to accurately confirm the location where urine leakage has occurred. In that case, it becomes difficult for the user or caregiver to properly understand the state of the absorbent article being worn and to identify the cause of urine leakage. In addition, because the color of used tea leaves is close to the color of urine, it may be difficult to accurately confirm the color of the urine, such as mistaking the color of the urine on the used tea leaves for the actual color of urine. In that case, it becomes difficult for the user or caregiver to properly understand the health condition of the user.

本発明の目的は、尿の臭気を抑制することと、尿漏れが生じた場所及び尿の色を正確に確認することとを両立させることが可能な吸収性物品を提供することにある。 The objective of the present invention is to provide an absorbent article that can simultaneously suppress the odor of urine and accurately identify the location of urine leakage and the color of the urine.

本発明の吸収性物品は、長手方向、幅方向、及び厚さ方向を有し、表面シートと、前記表面シートの非肌側に配置された吸収体と、前記表面シートと前記吸収体との間に配置され、活性炭の粒子を含む活性炭部材と、を備える吸収性物品であって、前記活性炭部材は、平面視で、前記吸収体の前記長手方向の一方の端縁から他方の端縁まで連続的に延び、長手方向中心線を挟んで前記幅方向の両側に並んだ一対の活性炭シートを含み、前記吸収性物品は、平面視で、前記一対の活性炭シートの前記幅方向の内側において、前記吸収体の前記長手方向の一方の端縁から他方の端縁まで連続して延び、活性炭シートを含まない中央非含有領域と、平面視で、前記一対の活性炭シートの前記幅方向の外側において、前記吸収体の前記幅方向の両端に位置し、活性炭シートを含まない端部非含有領域と、を有する、吸収性物品。 The absorbent article of the present invention has a longitudinal direction, a width direction, and a thickness direction, and is provided with a top sheet, an absorbent body arranged on the non-skin side of the top sheet, and an activated carbon member arranged between the top sheet and the absorbent body and containing activated carbon particles, the activated carbon member including a pair of activated carbon sheets that extend continuously from one end edge to the other end edge of the absorbent body in the longitudinal direction in a plan view and are arranged on both sides of the longitudinal center line in the width direction, the absorbent article including a central non-containing region that does not contain an activated carbon sheet, which extends continuously from one end edge to the other end edge of the absorbent body in the longitudinal direction on the inner side of the pair of activated carbon sheets in the width direction in a plan view, and an end non-containing region that does not contain an activated carbon sheet, which is located on both ends of the absorbent body in the width direction on the outer side of the pair of activated carbon sheets in the width direction in a plan view.

本発明によれば、尿の臭気を抑制することと、尿漏れが生じた場所及び尿の色を正確に確認することとを両立させることが可能な吸収性物品を提供できる。 The present invention provides an absorbent article that can simultaneously suppress the odor of urine and accurately identify the location of urine leakage and the color of the urine.

FIG.

本実施形態は、以下の態様に関する。
［態様１］
長手方向、幅方向、及び厚さ方向を有し、表面シートと、前記表面シートの非肌側に配置された吸収体と、前記表面シートと前記吸収体との間に配置され、活性炭の粒子を含む活性炭部材と、を備える吸収性物品であって、前記活性炭部材は、平面視で、前記吸収体の前記長手方向の一方の端縁から他方の端縁まで連続的に延び、長手方向中心線を挟んで前記幅方向の両側に並んだ一対の活性炭シートを含み、前記吸収性物品は、平面視で、前記一対の活性炭シートの前記幅方向の内側において、前記吸収体の前記長手方向の一方の端縁から他方の端縁まで連続して延び、活性炭シートを含まない中央非含有領域と、平面視で、前記一対の活性炭シートの前記幅方向の外側において、前記吸収体の前記幅方向の両端に位置し、活性炭シートを含まない端部非含有領域と、を有する、吸収性物品。 The present embodiment relates to the following aspects.
[Aspect 1]
An absorbent article having a longitudinal direction, a width direction, and a thickness direction, comprising a top sheet, an absorbent body arranged on the non-skin side of the top sheet, and an activated carbon member arranged between the top sheet and the absorbent body and containing activated carbon particles, wherein the activated carbon member includes a pair of activated carbon sheets that, in a planar view, extend continuously from one end edge to the other end edge of the absorbent body in the longitudinal direction and are lined up on both sides in the width direction across a longitudinal center line, and the absorbent article has a central non-containing region that, in a planar view, extends continuously from one end edge to the other end edge of the absorbent body in the longitudinal direction, on the inner side of the pair of activated carbon sheets, and does not contain an activated carbon sheet, and end non-containing regions that, in a planar view, are located on both ends of the absorbent body in the width direction, on the outer side of the pair of activated carbon sheets, and do not contain an activated carbon sheet.

本吸収性物品は、吸収体の肌側に、長手方向中心線を挟んで幅方向の両側に並んだ一対の活性炭シートを備えている。そのため、表面シートや吸収体の尿の臭気を吸収し、抑制することができる。そのとき、吸収性物品は、幅方向において、一対の活性炭シートの内側及び外側、すなわち、平面視で、吸収体の中央部及び両端部に対応する位置に、それぞれ、活性炭シートを含まない中央非含有領域及び端部非含有領域を備えている。そのため、まず、尿が主に***される領域である吸収体の中央部に活性炭シートが存在しない。それにより、吸収体の中央部に吸収された尿の色を正確に確認できる。
更に、尿漏れが生じ得る吸収体の長手方向及び幅方向の両端部に活性炭シートが存在しない。それにより、長手方向及び幅方向の両端部にまで尿が拡散したか否か、すなわち、尿漏れが生じたか否か、及び、尿漏れの位置を、尿の色の有無で容易に確認できる。その際、消臭剤として茶殻でなく活性炭の粒子を用いているため、活性炭の粒子が存在する領域が黒色系となるので、その領域の尿の色と実際の尿の色とを容易に区別でき、その領域の尿の色を実際の尿と誤認することを抑制できる。
このように、この吸収性物品では、尿の臭気が抑制されつつ、使用者又は介護者が、尿漏れが生じた場所を正確に確認することができる。それにより、吸収性物品の装着の状態を把握し、尿漏れの原因を特定して、尿漏れの再発の抑制に役立てることができる。また、そのときの尿の色を正確に確認することができ、使用者の健康状態を容易に把握することができる。したがって、尿の臭気を抑制することと、尿漏れが生じた場所及び尿の色を正確に確認することとを両立させることができる。 The absorbent article includes a pair of activated carbon sheets arranged on both sides of the longitudinal centerline on the skin side of the absorbent body in the width direction. This allows the absorbent body to absorb and suppress the urine odor of the top sheet and the absorbent body. In this case, the absorbent article includes a central non-containing region and an end non-containing region that do not include activated carbon sheets on the inside and outside of the pair of activated carbon sheets in the width direction, i.e., at positions corresponding to the center and both ends of the absorbent body in a plan view. Therefore, first, the activated carbon sheet is not present in the center of the absorbent body, which is the area where urine is mainly excreted. This allows the color of urine absorbed in the center of the absorbent body to be accurately confirmed.
Furthermore, there is no activated carbon sheet at both ends in the longitudinal and width directions of the absorbent where urine leakage may occur. As a result, it is easy to check whether urine has spread to both ends in the longitudinal and width directions, i.e., whether urine leakage has occurred and the location of urine leakage, by the presence or absence of urine color. In this case, since activated carbon particles are used as the deodorant instead of used tea leaves, the area where the activated carbon particles are present is black in color, so the color of urine in that area can be easily distinguished from the actual color of urine, and it is possible to prevent the color of urine in that area from being mistaken for actual urine.
In this way, this absorbent article allows the user or caregiver to accurately confirm the location of urine leakage while suppressing the urine odor. This allows the user to understand how the absorbent article is being worn, identify the cause of urine leakage, and help prevent recurrence of urine leakage. In addition, the color of the urine at that time can be accurately confirmed, making it easy to understand the user's health condition. Therefore, it is possible to simultaneously suppress the urine odor and accurately confirm the location of urine leakage and the color of the urine.

［態様２］
前記吸収体は、上層吸収体と、前記上層吸収体の非肌側に位置し、肌側の表面の全体が前記上層吸収体に覆われている下層吸収体と、を含む、態様１に記載の吸収性物品。
本吸収性物品では、吸収体が、上層吸収体と、上層吸収体の非肌側に位置する下層吸収体と、を備えている。そして、下層吸収体における肌側の表面の全体は、上層吸収体に覆われている。それにより、下層吸収体から発生する尿の臭気が肌側へ拡散することを上層吸収体により遮断又は抑制できる。よって、吸収体に存在する尿の臭気を抑制できる。 [Aspect 2]
The absorbent article according to claim 1, wherein the absorbent body includes an upper absorbent body and a lower absorbent body located on the non-skin side of the upper absorbent body, the entire skin-side surface of which is covered by the upper absorbent body.
In this absorbent article, the absorbent body includes an upper absorbent body and a lower absorbent body located on the non-skin side of the upper absorbent body. The entire skin-side surface of the lower absorbent body is covered by the upper absorbent body. This allows the upper absorbent body to block or suppress the urine odor generated from the lower absorbent body from diffusing toward the skin side. This allows the urine odor present in the absorbent body to be suppressed.

［態様３］
前記上層吸収体及び前記下層吸収体は、いずれも高吸水性ポリマーとパルプ繊維とを含み、高吸水性ポリマーとパルプ繊維との合計質量に対するパルプ繊維の質量の比率をパルプ繊維比率とすると、前記上層吸収体のパルプ繊維比率は、前記下層吸収体のパルプ繊維比率よりも高い、態様２に記載の吸収性物品。
本吸収性物品では、上層吸収体のパルプ繊維比率が相対的に高いため、上層吸収体において、平面方向（長手方向及び／又は幅方向）に広く尿を拡散させることができる。そのため、活性炭シートを広く有効に用いることができ、活性炭シートにより尿の臭気を効率的に抑制できる。 [Aspect 3]
The absorbent article of claim 2, wherein the upper absorbent body and the lower absorbent body both contain a superabsorbent polymer and pulp fiber, and the ratio of the mass of the pulp fiber to the total mass of the superabsorbent polymer and the pulp fiber is defined as the pulp fiber ratio, and the pulp fiber ratio of the upper absorbent body is higher than the pulp fiber ratio of the lower absorbent body.
In this absorbent article, since the upper absorbent body has a relatively high pulp fiber ratio, urine can be widely diffused in the planar direction (longitudinal direction and/or width direction) in the upper absorbent body, and therefore the activated carbon sheet can be used widely and effectively, and the activated carbon sheet can efficiently suppress the urine odor.

［態様４］
前記中央非含有領域において、前記上層吸収体及び前記下層吸収体は、前記長手方向に沿って延び、前記厚さ方向に窪んでいるスリットを有する、態様２又は３に記載の吸収性物品。
本吸収性物品では、中央非含有領域、すなわち活性炭シートの存在しない領域において、上層吸収体及び下層吸収体は、長手方向に沿って延び、厚さ方向に窪んでいるスリットを有している。そのため、***された尿は、主にスリットに誘導され、スリットを介して素早く上層吸収体及び下層吸収体に到達し、上層吸収体及び下層吸収体に素早く吸収され、拡散できる。それゆえ、上層吸収体及び下層吸収体よりも肌側に位置する一対の活性炭シートにより、上層吸収体及び下層吸収体から発生する尿の臭気を遮断又は抑制できる。したがって、吸収体に存在する尿の臭気を抑制できる。 [Aspect 4]
The absorbent article according to aspect 2 or 3, wherein in the central non-containing region, the upper absorbent body and the lower absorbent body have a slit extending along the longitudinal direction and recessed in the thickness direction.
In this absorbent article, in the central non-containing region, i.e., the region where no activated carbon sheets are present, the upper and lower absorbent bodies have slits that extend along the longitudinal direction and are recessed in the thickness direction. Therefore, excreted urine is mainly guided to the slits, quickly reaches the upper and lower absorbent bodies via the slits, and is quickly absorbed and diffused by the upper and lower absorbent bodies. Therefore, the pair of activated carbon sheets located closer to the skin than the upper and lower absorbent bodies can block or suppress the urine odor generated from the upper and lower absorbent bodies. Therefore, the urine odor present in the absorbent body can be suppressed.

［態様５］
前記表面シートにおける前記幅方向の両側に、前記長手方向に沿って延び、前記幅方向に所定の間隔を空けて配置された一対の防漏壁を更に備え、前記一対の防漏壁の各々は、前記幅方向の外側の端縁を前記表面シートに固定された固定端とされ、前記幅方向の内側の端縁を自由端とされ、前記固定端は、前記一対の活性炭シートの各々における前記幅方向の外側の端縁よりも、前記幅方向の外側に配置される、態様１乃至４のいずれか一項に記載の吸収性物品。
本吸収性物品では、防漏壁の固定端は、活性炭シートにおける幅方向の外側の端縁よりも、幅方向の外側に配置される。すなわち、幅方向において、活性炭シートは、防漏壁が尿を堰き止める位置よりも外側には配置されておらず、尿が主に存在する領域に配置されている。したがって、活性炭シートを広く有効に用いることができ、活性炭シートにより尿の臭気を効率的に抑制できる。 [Aspect 5]
An absorbent article as described in any one of aspects 1 to 4, further comprising a pair of leakproof walls extending along the longitudinal direction and arranged at a predetermined interval in the width direction on both sides of the top sheet in the width direction, each of the pair of leakproof walls having an outer edge in the width direction as a fixed end fixed to the top sheet and an inner edge in the width direction as a free end, and the fixed ends are arranged outer in the width direction than the outer edges in the width direction of each of the pair of activated carbon sheets.
In this absorbent article, the fixed end of the leak barrier is positioned outboard of the outer edge of the activated carbon sheet in the width direction. That is, in the width direction, the activated carbon sheet is not positioned outboard of the position where the leak barrier blocks urine, but is positioned in the area where urine is mainly present. Therefore, the activated carbon sheet can be used widely and effectively, and the activated carbon sheet can efficiently suppress the odor of urine.

［態様６］
前記長手方向に沿って延び、前記幅方向に間隔を空けて設けられた、前記吸収性物品を前記幅方向に折り畳むための一対の折り線を有し、前記幅方向において、前記一対の折り線の各々は、前記一対の活性炭シートの各々に重なる、態様１乃至５のいずれか一項に記載の吸収性物品。
本吸収性物品は、一対の折り線で幅方向に三つ折りされる。ここで、一対の折り線の各々が一対の活性炭シートの各々よりも内側に位置していると、吸収性物品が折り畳まれたとき、吸収性物品における折り畳まれた一対の活性炭シートの各々が中央非含有領域に表面シートを介して厚さ方向に重なることになる。その場合、活性炭シートの活性炭の粒子が脱落すると、表面シートを介して中央非含有領域に付着して、中央非含有領域での尿の色を確認し難くなるおそれがある。そこで、この吸収性物品では、一対の折り線の各々が、一対の活性炭シートの各々に重なるようにしている。そのため、吸収性物品における折り畳まれた一対の活性炭シートの各々において、中央非含有領域に厚さ方向に重なる領域を低減できる。それにより、中央非含有領域の表面シートに活性炭シートの活性炭の粒子が付着して中央非含有領域での尿の色を確認し難くなることを抑制できる。 [Aspect 6]
The absorbent article of any one of claims 1 to 5, further comprising a pair of fold lines extending along the longitudinal direction and spaced apart in the width direction for folding the absorbent article in the width direction, and each of the pair of fold lines overlaps each of the pair of activated carbon sheets in the width direction.
The absorbent article is folded in three widthwise at a pair of fold lines. Here, if each of the pair of fold lines is located inside each of the pair of activated carbon sheets, when the absorbent article is folded, each of the folded pair of activated carbon sheets in the absorbent article will overlap the central non-containing region in the thickness direction via the surface sheet. In that case, if activated carbon particles of the activated carbon sheet fall off, they may adhere to the central non-containing region via the surface sheet, making it difficult to confirm the color of urine in the central non-containing region. Therefore, in this absorbent article, each of the pair of fold lines is made to overlap each of the pair of activated carbon sheets. Therefore, the area that overlaps the central non-containing region in the thickness direction in each of the folded pair of activated carbon sheets in the absorbent article can be reduced. This can suppress the activated carbon particles of the activated carbon sheet from adhering to the surface sheet of the central non-containing region, making it difficult to confirm the color of urine in the central non-containing region.

［態様７］
前記幅方向において、前記一対の折り線の各々は、前記一対の活性炭シートの各々の中心よりも外側に位置する、態様６に記載の吸収性物品。
本吸収性物品では、一対の折り線の各々は、一対の活性炭シートの各々の中心よりも外側の位置している。そのため、吸収性物品における折り畳まれた一対の活性炭シートの各々において、中央非含有領域に厚さ方向に重なる領域をなくすことができる。したがって、中央非含有領域に活性炭の粒子が付着して中央非含有領域の表面シートでの尿の色を確認し難くなることを確実に抑制できる。 [Aspect 7]
7. The absorbent article according to claim 6, wherein each of the pair of fold lines is located outside a center of each of the pair of activated carbon sheets in the width direction.
In the absorbent article, each of the pair of fold lines is located outside the center of each of the pair of activated carbon sheets. Therefore, in each of the pair of folded activated carbon sheets in the absorbent article, there is no area that overlaps with the central non-containing region in the thickness direction. Therefore, it is possible to reliably prevent activated carbon particles from adhering to the central non-containing region, making it difficult to check the color of urine on the surface sheet of the central non-containing region.

［態様８］
前記表面シートにおける前記幅方向の両側に、前記長手方向に沿って延び、前記幅方向に所定の間隔を空けて配置された一対の防漏壁を更に備え、前記一対の防漏壁の各々は、前記一対の活性炭シートの各々の少なくとも一部と前記厚さ方向に重なっている、態様６又は７に記載の吸収性物品。
本吸収性物品では、平面視で、一対の防漏壁の各々が一対の活性炭シートの各々の少なくとも一部を（、表面シートを介して）覆っている。そのため、吸収性物品が折り畳まれたとき、吸収性物品のうちの折り畳まれた部分における一対の活性炭シートの各々と、当該部分が折り重なった中央非含有領域との間に、一対の防漏壁を介在させることができる。それにより、中央非含有領域の表面シートに活性炭シートの活性炭の粒子が付着して中央非含有領域での尿の色を確認し難くなることを抑制できる。 [Aspect 8]
An absorbent article as described in aspect 6 or 7, further comprising a pair of leak-proof walls extending along the longitudinal direction and arranged at a predetermined interval in the width direction on both sides of the top sheet in the width direction, each of the pair of leak-proof walls overlapping at least a portion of each of the pair of activated carbon sheets in the thickness direction.
In the present absorbent article, in a plan view, each of the pair of leak-proof walls covers at least a portion of each of the pair of activated carbon sheets (through the top sheet). Therefore, when the absorbent article is folded, the pair of leak-proof walls can be interposed between each of the pair of activated carbon sheets in the folded portion of the absorbent article and the central non-containing region where the portion is folded over. This can prevent activated carbon particles of the activated carbon sheet from adhering to the top sheet of the central non-containing region, making it difficult to check the color of urine in the central non-containing region.

［態様９］
前記活性炭の粒子うちの少なくとも９０体積％分の粒子は、１μｍ以上、６０μｍ以下の粒径を有する、態様１乃至８のいずれか一項に記載の吸収性物品。
本吸収性物品では、活性炭の粒子うちの少なくとも９０体積％分の粒子は、１μｍ以上、６０μｍ以下の粒径を有している。このように、活性炭の粒子の大部分を６０μｍ以下の粒径にすることで、活性炭シートのシート本体の構成繊維間に容易に入り込ませることができ、それにより、シート本体に容易に担持することができる。また、活性炭の粒子の大部分を１μｍ以上の粒径にすることで、活性炭の粒子の一部がシート本体から脱落したとしても、脱落した粒子が表面シートを通り抜け難くできる。それらにより、中央非含有領域に活性炭の粒子が付着して中央非含有領域での尿の色を確認し難くなることを抑制できる。 [Aspect 9]
9. The absorbent article of any one of the preceding claims, wherein at least 90% by volume of the particles of the activated carbon have a particle size of 1 μm or more and 60 μm or less.
In this absorbent article, at least 90% by volume of the activated carbon particles have a particle size of 1 μm or more and 60 μm or less. In this way, by making the majority of the activated carbon particles 60 μm or less in particle size, they can easily penetrate between the constituent fibers of the sheet body of the activated carbon sheet, and therefore can be easily supported by the sheet body. In addition, by making the majority of the activated carbon particles 1 μm or more in particle size, even if some of the activated carbon particles fall off from the sheet body, the fallen particles can be made less likely to pass through the top sheet. As a result, it is possible to prevent activated carbon particles from adhering to the central non-containing region, making it difficult to check the color of urine in the central non-containing region.

［態様１０］
前記一対の活性炭シートと前記表面シートとの間に、高吸水性ポリマーを含む高吸水性ポリマーシートを更に備える、態様１乃至９のいずれか一項に記載の吸収性物品。
本吸収性物品は、一対の活性炭シートと表面シートとの間に高吸水性ポリマーシート（ＳＡＰシート）を更に備えている。それにより、ＳＡＰシートが尿を吸収して膨潤したとき、ＳＡＰシートよりも非肌側に位置する吸収体から発生する尿の臭気を、膨潤したＳＡＰシートにより遮断又は抑制できる。よって、吸収体に存在する尿の臭気を抑制できる。 [Aspect 10]
The absorbent article according to any one of the preceding claims, further comprising a superabsorbent polymer sheet between the pair of activated carbon sheets and the top sheet, the superabsorbent polymer sheet including a superabsorbent polymer.
The absorbent article further includes a superabsorbent polymer sheet (SAP sheet) between the pair of activated carbon sheets and the top sheet. As a result, when the SAP sheet absorbs urine and swells, the swollen SAP sheet can block or suppress the urine odor generated from the absorbent body located on the non-skin side of the SAP sheet. Thus, the urine odor present in the absorbent body can be suppressed.

［態様１１］
前記一対の活性炭シートと前記表面シートとの間に、拡散シートを更に備える、態様１乃至１０のいずれか一項に記載の吸収性物品。
本吸収性物品では、一対の活性炭シートと表面シートとの間に、平面方向に広く尿を拡散させる拡散シートを更に備えている。この拡散シートは、活性炭シートを肌側から覆っているので、活性炭の粒子の一部が活性炭シートのシート本体から脱落したとしても、脱落した粒子が表面シートに到達することを遮断又は抑制できる。よって、中央非含有領域に活性炭の粒子が付着して中央非含有領域での尿の色を確認し難くなるのを抑制できる。 [Aspect 11]
Aspect 11. The absorbent article of any one of aspects 1 to 10, further comprising a diffusion sheet between the pair of activated carbon sheets and the top sheet.
The absorbent article further includes a diffusion sheet between the pair of activated carbon sheets and the top sheet, which diffuses urine widely in the planar direction. This diffusion sheet covers the activated carbon sheet from the skin side, so that even if some of the activated carbon particles fall off from the main body of the activated carbon sheet, it can block or prevent the fallen particles from reaching the top sheet. This prevents activated carbon particles from adhering to the central non-containing region, making it difficult to check the color of urine in the central non-containing region.

However, FIG. 1 is a plan view of the absorbent article 1, FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1, FIG. 3 is a cross-sectional view taken along line III-III in FIG. 1, and FIG. 4 is a plan view showing an example of the configuration of an absorbent body 4 and a pair of activated carbon sheets 6 of the absorbent article 1 in FIG. 1. The absorbent article 1 has a longitudinal direction L, a width direction W, and a thickness direction T that are perpendicular to each other, and has a longitudinal centerline CL that passes through the center of the width direction W and extends in the longitudinal direction L, and a widthwise centerline CW that passes through the center of a urination area STA (described later) in the longitudinal direction L and extends in the width direction W. The direction and side approaching the longitudinal centerline CL are respectively defined as the inward and inner sides in the width direction W, and the direction and side moving away from the longitudinal centerline CL are respectively defined as the outward and outer sides in the width direction W. The direction and side approaching the widthwise centerline CW are respectively the inward and inner sides of the longitudinal direction L, and the direction and side moving away from the widthwise centerline CW are respectively the outward and outer sides of the longitudinal direction L. The terms "skin side" and "non-skin side" refer to the side relatively closer to and farther from the skin surface of the wearer in the thickness direction T when the absorbent article 1 is worn by the wearer. The term "planar view" refers to the absorbent article 1 being unfolded on a plane including the longitudinal direction L and the width direction W, as viewed from above (skin side) in the thickness direction T, and the term "planar shape" refers to the shape as seen in a planar view. The term "planar direction" refers to any direction parallel to a plane including the width direction W and the longitudinal direction L. In FIG. 1, the upper side is the front side or ventral side of the longitudinal direction L, and the lower side is the rear side or dorsal side of the longitudinal direction L. These definitions are used not only for the absorbent article 1, but also for each material arranged in the absorbent article 1. In addition, when a member, structure, shape, etc. is "along the longitudinal direction L," it includes not only when the member is parallel to the longitudinal direction L, but also when the component Dx of the longitudinal direction L of the member is greater than the component Dy of the width direction W of the member. Similarly, when a member is "along the width direction W," it includes not only when the member is parallel to the width direction W, but also when the component Dy of the width direction W of the member is greater than the component Dx of the longitudinal direction L of the member. When a curved or curved member is "along the longitudinal direction L" or "along the width direction W," the components Dx and Dy of the tangents of each point on the curve are evaluated as described above. The end of a certain direction (e.g., longitudinal direction L, width direction W) of a certain member refers to a range of dimensions from the edge of the member in that direction to 1/4 (preferably 1/8) or less of the overall length in that direction.

吸収性物品１は、長手方向Ｌに沿って前側から後側へ向かって並ぶ腹側部Ａ１、股間部Ａ２及び背側部Ａ３を有し、平面視にて、股間部Ａ２が幅方向Ｗにくびれた瓢箪形状を有する。ただし、腹側部Ａ１は装着者の腹部に当接する部分であり、股間部Ａ２は装着者の股間部に当接する部分であり、背側部Ａ３は装着者の尻部及び背部に当接する部分である。ただし、吸収性物品１の形状は、長手方向Ｌに長い形状であれば、この形状に限定されず、例えば、長手方向Ｌに長い、矩形状、長手方向Ｌの両端部が外側に略半円形の矩形状、砂時計形状などであってもよい。吸収性物品１は、例えば長手方向Ｌの寸法は３５０～９６０ｍｍであり、幅方向Ｗの寸法は１６０～６００ｍｍである。 The absorbent article 1 has a ventral portion A1, a crotch portion A2, and a back portion A3 aligned from the front to the back along the longitudinal direction L, and in a plan view, the crotch portion A2 has a gourd shape narrowed in the width direction W. However, the ventral portion A1 is the portion that abuts against the wearer's abdomen, the crotch portion A2 is the portion that abuts against the wearer's crotch, and the back portion A3 is the portion that abuts against the wearer's buttocks and back. However, the shape of the absorbent article 1 is not limited to this shape as long as it is long in the longitudinal direction L, and may be, for example, a rectangular shape that is long in the longitudinal direction L, a rectangular shape with both ends in the longitudinal direction L that are roughly semicircular on the outside, an hourglass shape, or the like. For example, the absorbent article 1 has a dimension in the longitudinal direction L of 350 to 960 mm, and a dimension in the width direction W of 160 to 600 mm.

吸収性物品１は、表面シート２と、裏面シート３と、吸収体４と、を備える。表面シート２は、肌側に位置する液透過性シートである。表面シート２としては、例えば液透過性の不織布や織布、液透過孔が形成された合成樹脂フィルム、これらの複合シートなどが挙げられる。裏面シート３は、非肌側に位置する液不透過性シートである。裏面シート３としては、例えば液不透過性の不織布や合成樹脂フィルム、これらの複合シートなどが挙げられる。吸収体４は、表面シート２と裏面シート３との間に位置する、液吸収性及び液保持性を有する部材である。吸収体４の材料としては、例えばパルプ繊維、合成繊維、高分子吸収体などが挙げられる。なお、表面シート２、裏面シート３及び吸収体４の厚さ、坪量等は吸収性物品１の吸収性能等を考慮して適宜調整される。各資材同士は接着剤等の公知の方法で接合されている。 The absorbent article 1 comprises a top sheet 2, a back sheet 3, and an absorbent 4. The top sheet 2 is a liquid-permeable sheet located on the skin side. Examples of the top sheet 2 include liquid-permeable nonwoven fabric or woven fabric, synthetic resin film with liquid-permeable holes, and composite sheets of these. The back sheet 3 is a liquid-impermeable sheet located on the non-skin side. Examples of the back sheet 3 include liquid-impermeable nonwoven fabric or synthetic resin film, and composite sheets of these. The absorbent 4 is a member that is located between the top sheet 2 and the back sheet 3 and has liquid absorption and liquid retention properties. Examples of materials for the absorbent 4 include pulp fiber, synthetic fiber, and polymer absorbent. The thickness, basis weight, etc. of the top sheet 2, back sheet 3, and absorbent 4 are appropriately adjusted taking into account the absorption performance, etc. of the absorbent article 1. Each material is bonded to the other materials by a known method such as adhesive.

吸収性物品１は、表面シート２と吸収体４との間に配置され、活性炭の粒子を含む活性炭部材と、を備えている。活性炭部材は、平面視で、吸収体４の長手方向Ｌの一方の端縁４Ｔ１から他方の端縁４Ｔ２まで連続的に延び、長手方向中心線ＣＬを挟んで幅方向Ｗの両側に並んだ一対の活性炭シート６を含んでいる。本実施形態では、一対の活性炭シート６の各々は、活性炭の粒子が担持された液透過性シートであり、平面視で、略矩形状を有している。活性炭シート６としては、繊維で形成されたシート本体に活性炭の粒子が担持されたものが挙げられ、例えば、パルプ等の天然繊維やポリエチレン等の合成繊維と活性炭の粒子とを用いて作製された混抄紙が挙げられる。活性炭としては、特に限定されないが、例えば、ヤシガラ、竹、木材等の炭化物（ヤシガラ炭や竹炭、木炭等）などが挙げられる。活性炭シート６は、活性炭のほかに、ゼオライト、シリカゲル、アルミナ、多孔質ガラスのような公知の消臭材料を更に含んでもよい。 The absorbent article 1 is provided with an activated carbon member that is disposed between the top sheet 2 and the absorbent body 4 and contains particles of activated carbon. The activated carbon member includes a pair of activated carbon sheets 6 that extend continuously from one end edge 4T1 to the other end edge 4T2 in the longitudinal direction L of the absorbent body 4 in a plan view, and are arranged on both sides in the width direction W across the longitudinal center line CL. In this embodiment, each of the pair of activated carbon sheets 6 is a liquid-permeable sheet carrying activated carbon particles, and has a substantially rectangular shape in a plan view. Examples of the activated carbon sheet 6 include a sheet body formed of fibers carrying activated carbon particles, such as a mixed paper made of natural fibers such as pulp or synthetic fibers such as polyethylene and activated carbon particles. Examples of activated carbon include, but are not limited to, carbonized materials such as coconut shells, bamboo, and wood (coconut shell charcoal, bamboo charcoal, wood charcoal, etc.). In addition to activated carbon, the activated carbon sheet 6 may further contain known deodorizing materials such as zeolite, silica gel, alumina, and porous glass.

吸収性物品１は、平面視で、活性炭シート６を含まない中央非含有領域ＭＮＡと、活性炭シート６を含まない端部非含有領域ＥＮＡと、を有している。中央非含有領域ＭＮＡは、平面視で、一対の活性炭シート６の幅方向Ｗの内側（吸収体４の幅方向Ｗの中央部）において、吸収体４の長手方向Ｌの一方の端縁４Ｔ１から他方の端縁４Ｔ２まで連続して延びている。本実施形態では、その形状は、略矩形状であるが、特に限定はされない。一方、端部非含有領域ＥＮＡは、平面視で、一対の活性炭シート６の幅方向Ｗの外側において、吸収体４の幅方向Ｗの両端部に位置している。本実施形態では、長手方向Ｌには股間部Ａ２の括れた部分、腹側部Ａ１の前側の端部、及び、背側部Ａ３の後側の端部を除いた位置に存在している。その形状は、幅方向Ｗの内側を下底とする略台形状であるが、特に限定はされない。なお、吸収性物品１において、平面視で、一対の活性炭シート６の領域は、活性炭シート６を含んだ含有領域ＡＣＡということができる。 The absorbent article 1 has a central non-containing area MNA that does not include the activated carbon sheet 6 in a plan view, and an end non-containing area ENA that does not include the activated carbon sheet 6. The central non-containing area MNA extends continuously from one end edge 4T1 to the other end edge 4T2 in the longitudinal direction L of the absorbent 4 on the inside of the width direction W of the pair of activated carbon sheets 6 (the center of the width direction W of the absorbent 4) in a plan view. In this embodiment, the shape is approximately rectangular, but is not particularly limited. On the other hand, the end non-containing area ENA is located at both ends of the width direction W of the absorbent 4 on the outside of the width direction W of the pair of activated carbon sheets 6 in a plan view. In this embodiment, it exists in the longitudinal direction L at a position excluding the narrowed part of the crotch part A2, the front end of the abdominal part A1, and the rear end of the back part A3. The shape is approximately trapezoidal with the inside of the width direction W as the base, but is not particularly limited. In addition, in the absorbent article 1, the area of the pair of activated carbon sheets 6 in a plan view can be referred to as an area ACA that contains the activated carbon sheets 6.

このとき、吸収体４は、平面視で、一対の活性炭シート６と重ならず、中央非含有領域ＭＮＡと重なる、吸収体４の幅方向Ｗの中央部に位置する中央部分３０を有している。吸収体４は、更に、平面視で、一対の活性炭シート６と重ならず、吸収体４の幅方向Ｗの端部に位置し、端部非含有領域ＥＮＡの長手方向Ｌの前方の部分と重なる、前方端部部分３１と、後方の部分と重なる後方端部部分３２とを有している。吸収性物品１では、肌側から見て、一対の活性炭シート６の存在する領域が、表面シート２を介して、活性炭の粒子により、やや黒みがかって見える。したがって、その領域が尿で湿った場合、その尿の色は、活性炭の粒子の黒色を反映して、黒みがかった色に見え、実際とは異なる色に見える。一方、吸収性物品１では、肌側から見て、中央非含有領域ＭＮＡ及び端部非含有領域ＥＮＡが、表面シート２を介して、吸収体４の中央部分３０、前方端部部分３１及び後方端部部分３２により、白く見える。したがって、その領域が尿で湿った場合、その尿の色は、吸収体４の各部分の白色を反映して、実際の色と同じ色に見える。 In this case, the absorbent 4 has a central portion 30 located in the center of the width direction W of the absorbent 4, which does not overlap the pair of activated carbon sheets 6 in a plan view and overlaps with the central non-containing region MNA. The absorbent 4 further has a front end portion 31, which does not overlap the pair of activated carbon sheets 6 in a plan view and is located at the end of the absorbent 4 in the width direction W, and overlaps with the front portion in the longitudinal direction L of the end non-containing region ENA, and a rear end portion 32, which overlaps with the rear portion. In the absorbent article 1, when viewed from the skin side, the area where the pair of activated carbon sheets 6 are present appears slightly blackish due to the activated carbon particles through the top sheet 2. Therefore, when that area is wet with urine, the color of the urine appears blackish, reflecting the black color of the activated carbon particles, and appears to be a different color from the actual color. On the other hand, in the absorbent article 1, when viewed from the skin side, the central non-containing area MNA and the end non-containing area ENA appear white due to the central portion 30, the front end portion 31, and the rear end portion 32 of the absorbent body 4 through the top sheet 2. Therefore, when this area becomes wet with urine, the color of the urine reflects the white color of each portion of the absorbent body 4 and appears to be the same color as the actual color.

活性炭シート６の、厚さ、坪量、活性炭の粒子の量等は活性炭シート６の消臭機能等を考慮して適宜調整される。本実施形態では、活性炭シート６の厚さは、十分な量の活性炭の粒子を保持させる観点（下限）及び吸収性物品１を固くしない観点（上限）から、０．１～１０ｍｍが好ましく、０．２～５ｍｍがより好ましい。また、活性炭シート６の坪量の下限は、消臭機能を十分に発揮させる観点（下限）及び吸収性物品１を固くしない観点（上限）から、１～８０ｇ／ｍ2が好ましく、１０～６０ｇ／ｍ2がより好ましい。また、活性炭シート６中の活性炭の粒子の量（割合）は、消臭機能を十分に発揮させる観点（下限）及び活性炭の粒子の脱落を抑制する観点（上限）から、１～３０質量％割合が好ましく、２～１５質量％がより好ましい。 The thickness, basis weight, amount of activated carbon particles, etc. of the activated carbon sheet 6 are appropriately adjusted in consideration of the deodorizing function of the activated carbon sheet 6. In this embodiment, the thickness of the activated carbon sheet 6 is preferably 0.1 to 10 mm, more preferably 0.2 to 5 mm, from the viewpoint of retaining a sufficient amount of activated carbon particles (lower limit) and from the viewpoint of not hardening the absorbent article 1 (upper limit). The lower limit of the basis weight of the activated carbon sheet 6 is preferably 1 to 80 g/m 2 , more preferably 10 to 60 g/m 2, from the viewpoint of fully exerting the deodorizing function (lower limit) and from the viewpoint of not hardening the absorbent article 1 (upper limit). The amount (ratio) of activated carbon particles in the activated carbon sheet 6 is preferably 1 to 30 mass %, more preferably 2 to 15 mass %, from the viewpoint of fully exerting the deodorizing function (lower limit) and from the viewpoint of suppressing the falling off of the activated carbon particles (upper limit).

このような吸収性物品１は、吸収体４の肌側に、一対の活性炭シート６を備えているので、表面シート２や吸収体４の尿の臭気を一対の活性炭シート６で吸収し、抑制することができる。
そのとき、吸収性物品１は、幅方向Ｗにおいて、一対の活性炭シート６の内側及び外側の位置、すなわち、平面視で、吸収体４の幅方向Ｗの中央部（中央部分３０）及び両端部（前方端部部分３１及び後方端部部分３２）に対応する位置に、それぞれ、活性炭シート６を含まない中央非含有領域ＭＮＡ及び端部非含有領域ＥＮＡを備えている。
そのため、まず、尿が主に直接***される領域（排尿領域ＳＴＡ）である吸収体４の幅方向Ｗの中央部に、活性炭シート６が存在しない。それにより、吸収体４の中央部分３０に吸収された尿の色を、活性炭シート６の色に影響されずに、正確に確認できる。
更に、尿漏れが生じ得る吸収体４の長手方向Ｌ及び幅方向Ｗの両端部、すなわち、中央部分３０（中央非含有領域ＭＮＡ）の長手方向Ｌの両端部、及び、前方端部部分３１及び後方端部部分３２（端部非含有領域ＥＮＡ）に活性炭シート６が存在しない。それゆえ、長手方向Ｌ及び幅方向Ｗの両端部にまで尿が拡散したか否か、すなわち、尿漏れが生じたか否か、及び、尿漏れの位置を、中央部分３０、前方端部部分３１及び後方端部部分３２における尿の色の有無で容易に確認できる。その際、消臭剤として茶殻でなく活性炭の粒子を用いているため、活性炭の粒子が存在する領域が黒色系になるので、その領域での尿の色と実際の尿の色（中央部分３０、前方端部部分３１及び後方端部部分３２での尿の色）とを容易に区別でき、その領域の尿の色を実際の尿と誤認することを抑制できる。
このように、この吸収性物品１では、尿の臭気が抑制されつつ、使用者又は介護者が、尿漏れが生じた場所を正確に確認することができる。それにより、吸収性物品１の装着の状態を把握し、尿漏れの原因を特定して、尿漏れの再発の抑制に役立てることができる。また、そのときの尿の色を正確に確認することができ、使用者の健康状態を容易に把握することができる。したがって、尿の臭気を抑制することと、尿漏れが生じた場所や尿の色を正確に確認することとを両立させることができる。 Such an absorbent article 1 is provided with a pair of activated carbon sheets 6 on the skin side of the absorbent body 4, so that the pair of activated carbon sheets 6 can absorb and suppress the urine odor in the top sheet 2 and the absorbent body 4.
At this time, the absorbent article 1 has a central non-containing area MNA and an end non-containing area ENA that do not contain the activated carbon sheet 6 at positions on the inside and outside of a pair of activated carbon sheets 6 in the width direction W, i.e., at positions corresponding to the center (central portion 30) and both ends (front end portion 31 and rear end portion 32) of the absorbent body 4 in the width direction W when viewed in a plan view.
Therefore, first, the activated carbon sheet 6 is not present in the center of the absorbent 4 in the width direction W, which is the area where urine is mainly directly excreted (urination area STA). As a result, the color of the urine absorbed in the center portion 30 of the absorbent 4 can be accurately confirmed without being affected by the color of the activated carbon sheet 6.
Furthermore, the activated carbon sheet 6 is not present at both ends in the longitudinal direction L and width direction W of the absorbent 4 where urine leakage may occur, i.e., both ends in the longitudinal direction L of the central portion 30 (central non-containing area MNA) and the front end portion 31 and rear end portion 32 (end non-containing area ENA). Therefore, whether or not urine has spread to both ends in the longitudinal direction L and width direction W, i.e., whether or not urine leakage has occurred, and the location of urine leakage can be easily confirmed by the presence or absence of urine color in the central portion 30, the front end portion 31, and the rear end portion 32. In this case, since activated carbon particles are used as the deodorant instead of tea leaves, the area where the activated carbon particles are present becomes blackish, so that the color of urine in that area can be easily distinguished from the actual color of urine (the color of urine in the central portion 30, the front end portion 31, and the rear end portion 32), and it is possible to suppress misidentification of the color of urine in that area as actual urine.
In this way, this absorbent article 1 allows the user or caregiver to accurately confirm the location of urinary leakage while suppressing the urine odor. This allows the user or caregiver to understand the state of wearing the absorbent article 1, identify the cause of urinary leakage, and help prevent urinary leakage from recurring. In addition, the color of the urine at that time can be accurately confirmed, making it easy to understand the user's health condition. Therefore, it is possible to simultaneously suppress the urine odor and accurately confirm the location of urinary leakage and the color of the urine.

本実施形態では、吸収体４において、長手方向Ｌの前側又は後側の端縁から尿漏れが生じたか否かは、中央非含有領域ＭＮＡの長手方向Ｌの前側又は後側の端縁付近の尿の色から確認できる。吸収体４において、幅方向Ｗの右側又は左側の端縁のうちの長手方向Ｌの前側の端縁から尿漏れが生じたか否かは、幅方向Ｗの右側又は左側かつ長手方向Ｌの前側の非含有領域ＥＮＡの尿の色から確認できる。吸収体４において、幅方向Ｗの右側又は左側の端縁のうちの長手方向Ｌの後側の端縁から尿漏れが生じたか否かは、幅方向Ｗの右側又は左側かつ長手方向Ｌの後側の端部非含有領域ＥＮＡの尿の色から確認できる。このように、各領域は活性炭シート６により区分けされ、及び／又は、互いに離間されている。そのため、尿漏れを確認すべき位置を容易に把握でき、それにより、尿漏れの有無及び尿漏れの位置を一目瞭然に容易に把握できる。それにより、吸収性物品１の装着の状態を把握し、尿漏れの原因を特定して、尿漏れの再発の抑制に役立てることができる。 In this embodiment, in the absorbent 4, whether or not urine leakage has occurred from the front or rear edge in the longitudinal direction L can be confirmed from the color of urine near the front or rear edge in the longitudinal direction L of the central non-containing area MNA. In the absorbent 4, whether or not urine leakage has occurred from the front edge in the longitudinal direction L of the right or left edge in the width direction W can be confirmed from the color of urine in the non-containing area ENA on the right or left side in the width direction W and the front side in the longitudinal direction L. In the absorbent 4, whether or not urine leakage has occurred from the rear edge in the longitudinal direction L of the right or left edge in the width direction W can be confirmed from the color of urine in the end non-containing area ENA on the right or left side in the width direction W and the rear side in the longitudinal direction L. In this way, each area is divided by the activated carbon sheet 6 and/or separated from each other. Therefore, the position where urine leakage should be confirmed can be easily grasped, and therefore the presence or absence of urine leakage and the position of urine leakage can be easily and clearly grasped at a glance. This allows you to understand how the absorbent article 1 is being worn, identify the cause of urinary leakage, and help prevent recurrence of urinary leakage.

本実施形態では、活性炭シート６の活性炭の粒子は、少なくとも９０体積％分の粒子、好ましくは９５体積％分の粒子が、１μｍ以上、６０μｍ以下の粒径を有するような粒度分布を有している。活性炭の粒子の大部分を６０μｍ以下の粒径にすることで、活性炭の粒子を、活性炭シート６のシート本体の構成繊維間に容易に入り込ませることができ、それにより、シート本体に容易に担持することができる。また、活性炭の粒子の大部分を１μｍ以上の粒径にすることで、活性炭の粒子の一部がシート本体から脱落したとしても、脱落した粒子が表面シート２を通り抜け難くできる。それにより、脱落した粒子が中央非含有領域ＭＮＡに付着して中央非含有領域ＭＮＡでの尿の色を確認し難くなることを抑制できる。活性炭の粒子は、脱落を抑制する観点から、好ましくは、粒径２０μｍ超の粒子の割合が３０体積％未満であり、好ましくは、粒径３０μｍ超の粒子の割合が５体積％未満である。
このように、 In this embodiment, the activated carbon particles of the activated carbon sheet 6 have a particle size distribution in which at least 90% by volume of the particles, preferably 95% by volume of the particles, have a particle size of 1 μm or more and 60 μm or less. By making most of the activated carbon particles have a particle size of 60 μm or less, the activated carbon particles can be easily inserted between the constituent fibers of the sheet body of the activated carbon sheet 6, and therefore can be easily supported by the sheet body. In addition, by making most of the activated carbon particles have a particle size of 1 μm or more, even if some of the activated carbon particles fall off from the sheet body, the fallen particles can be made difficult to pass through the top sheet 2. This can prevent the fallen particles from adhering to the central non-containing area MNA and making it difficult to check the color of the urine in the central non-containing area MNA. From the viewpoint of preventing the activated carbon particles from falling off, the proportion of particles with a particle size of more than 20 μm is preferably less than 30% by volume, and preferably the proportion of particles with a particle size of more than 30 μm is less than 5% by volume.
in this way,

本実施形態では、吸収体４は、肌側に位置する上層吸収体２１と、上層吸収体２１の非肌側に位置し、肌側の表面の全体が上層吸収体２１に覆われている下層吸収体２２とを含んでいる。上層吸収体２１の形状は、股間部Ａ２が幅方向Ｗにくびれた瓢箪形状であり、吸収性物品１の形状に対して概ね相似な形状である。下層吸収体２２の形状は、長手方向Ｌに長く、幅方向Ｗが短い矩形状である。本実施形態では、上層吸収体２１の長手方向Ｌの両端縁は下層吸収体２２の長手方向Ｌの両端縁よりも長手方向Ｌの外側に位置し、よって、上層吸収体２１は下層吸収体２２よりも長手方向Ｌの両側に広く形成されている。また、上層吸収体２１の幅方向Ｗの両端縁は、下層吸収体２２の幅方向Ｗの両端縁よりも長手方向Ｌの外側に位置し、よって、上層吸収体２１は下層吸収体２２よりも幅方向Ｗの両側に広く形成されている。したがって、本実施形態では、吸収体４の長手方向Ｌの両端縁４Ｔ１、４Ｔ２は、上層吸収体２１の長手方向Ｌの両端縁２１Ｔ１、２１Ｔ２である。ただし、上層吸収体２１と下層吸収体２２の形状はこれらの形状に限定されず、下層吸収体２２の肌側の表面の全体が上層吸収体２１に覆われていれば他の形状でもよい。これらの形状としては、例えば、長手方向Ｌに長い矩形状、長手方向Ｌの両端部が外側に略半円形の矩形状、砂時計形状などが挙げられる。下層吸収体２２は、吸収性コア２３とその吸収性コア２３を包むコアラップ２４とを含んでいる。なお、上層吸収体２１及び下層吸収体２２の厚さ、坪量等は吸収体４の吸収性能等を考慮して適宜調整される。吸収体４は、一層であっても三層以上であってもよい。上層吸収体２１及び吸収性コア２３の材料としては、例えばパルプ繊維、高分子吸収体などが挙げられる。このように、下層吸収体２２全体が上層吸収体２１により肌側から覆われることで、下層吸収体２２から発生する尿の臭気が肌側へ拡散することを上層吸収体２１により遮断又は抑制できる。したがって、吸収体４に存在する尿の臭気を抑制できる。 In this embodiment, the absorbent body 4 includes an upper absorbent body 21 located on the skin side, and a lower absorbent body 22 located on the non-skin side of the upper absorbent body 21, the entire skin-side surface of which is covered by the upper absorbent body 21. The upper absorbent body 21 has a gourd shape with the crotch portion A2 narrowed in the width direction W, and is generally similar to the shape of the absorbent article 1. The lower absorbent body 22 has a rectangular shape that is long in the longitudinal direction L and short in the width direction W. In this embodiment, both ends of the upper absorbent body 21 in the longitudinal direction L are located outside both ends of the lower absorbent body 22 in the longitudinal direction L, and therefore the upper absorbent body 21 is formed wider on both sides in the longitudinal direction L than the lower absorbent body 22. In addition, both ends of the upper absorbent body 21 in the width direction W are located outside the both ends of the lower absorbent body 22 in the width direction W in the longitudinal direction L, and therefore the upper absorbent body 21 is formed wider on both sides in the width direction W than the lower absorbent body 22. Therefore, in this embodiment, both ends 4T1 and 4T2 in the longitudinal direction L of the absorbent body 4 are both ends 21T1 and 21T2 in the longitudinal direction L of the upper absorbent body 21. However, the shapes of the upper absorbent body 21 and the lower absorbent body 22 are not limited to these shapes, and other shapes may be used as long as the entire skin-side surface of the lower absorbent body 22 is covered by the upper absorbent body 21. Examples of these shapes include a rectangular shape that is long in the longitudinal direction L, a rectangular shape with both ends in the longitudinal direction L that are approximately semicircular on the outside, and an hourglass shape. The lower absorbent body 22 includes an absorbent core 23 and a core wrap 24 that wraps the absorbent core 23. The thickness, basis weight, etc. of the upper absorbent body 21 and the lower absorbent body 22 are appropriately adjusted taking into consideration the absorption performance, etc. of the absorbent body 4. The absorbent body 4 may be one layer or three or more layers. Examples of materials for the upper absorbent body 21 and the absorbent core 23 include pulp fibers and polymer absorbents. In this way, the entire lower absorbent body 22 is covered from the skin side by the upper absorbent body 21, and the upper absorbent body 21 can block or suppress the diffusion of urine odor generated from the lower absorbent body 22 to the skin side. Therefore, the urine odor present in the absorbent body 4 can be suppressed.

本実施形態では、上層吸収体２１及び下層吸収体２２は、いずれも高吸水性ポリマーとパルプ繊維とを含んでいる。高吸水性ポリマーとパルプ繊維との合計質量に対するパルプ繊維の質量の比率をパルプ繊維比率とすると、上層吸収体２１のパルプ繊維比率は、下層吸収体２２のパルプ繊維比率よりも高くなっている。上層吸収体２１のパルプ繊維比率が相対的に高いため、上層吸収体２１で平面方向（長手方向Ｌ及び／又は幅方向Ｗ）に広く尿を拡散させることができる。そのため、活性炭シート６を広く有効に用いることができ、活性炭シート６により尿の臭気を効率的に抑制できる。 In this embodiment, both the upper absorbent body 21 and the lower absorbent body 22 contain superabsorbent polymer and pulp fiber. If the ratio of the mass of pulp fiber to the total mass of the superabsorbent polymer and pulp fiber is defined as the pulp fiber ratio, the pulp fiber ratio of the upper absorbent body 21 is higher than that of the lower absorbent body 22. Since the pulp fiber ratio of the upper absorbent body 21 is relatively high, the upper absorbent body 21 can diffuse urine widely in the planar direction (longitudinal direction L and/or width direction W). Therefore, the activated carbon sheet 6 can be used widely and effectively, and the activated carbon sheet 6 can efficiently suppress the odor of urine.

本実施形態では、吸収性物品１は、一対の防漏壁７を更に備える。一対の防漏壁７の各々は、表面シート２の幅方向Ｗの両側に、長手方向Ｌに沿って延び、幅方向Ｗに所定の間隔を空けて配置されている。一対の防漏壁７の各々は、幅方向Ｗの外側の端縁は、表面シート２に固定された固定端ＦＸであり、内側の端縁は自由端ＦＲである。防漏壁７における自由端ＦＲの近傍には、長手方向Ｌに延びる、糸ゴムに例示される弾性部材８が配置されている。本実施形態では、吸収性物品１は、肌側の表面において、表面シート２の幅方向Ｗの両端部に接合され、長手方向Ｌに延びる一対のサイドシート５を備えており、一対の防漏壁７の各々は、一対のサイドシート５の各々の幅方向Ｗの内側の部分で形成されている。防漏壁７やサイドシート５としては、特に制限はないが、疎水性シート、例えば疎水性不織布が挙げられる。 In this embodiment, the absorbent article 1 further includes a pair of leak-proof walls 7. Each of the pair of leak-proof walls 7 extends along the longitudinal direction L on both sides of the width direction W of the top sheet 2, and is arranged at a predetermined interval in the width direction W. The outer edge of each of the pair of leak-proof walls 7 in the width direction W is a fixed end FX fixed to the top sheet 2, and the inner edge is a free end FR. An elastic member 8, exemplified by a rubber thread, extending in the longitudinal direction L is arranged near the free end FR of the leak-proof wall 7. In this embodiment, the absorbent article 1 includes a pair of side sheets 5 that are joined to both ends of the width direction W of the top sheet 2 on the skin side surface and extend in the longitudinal direction L, and each of the pair of leak-proof walls 7 is formed by the inner part of each of the pair of side sheets 5 in the width direction W. There are no particular limitations on the leak-proof walls 7 and the side sheets 5, but examples thereof include hydrophobic sheets, such as hydrophobic nonwoven fabrics.

本実施形態では、固定端ＦＸは、一対の活性炭シート６の各々における幅方向Ｗの外側の端縁６Ｅよりも、幅方向Ｗの外側に配置されている。すなわち、幅方向Ｗにおいて、活性炭シート６は、防漏壁７が尿を堰き止める位置よりも外側には配置されておらず、尿が主に存在する領域に配置されている。したがって、活性炭シート６を広く有効に用いることができ、活性炭シート６により尿の臭気を効率的に抑制できる。 In this embodiment, the fixed end FX is positioned outside the outer edge 6E in the width direction W of each of the pair of activated carbon sheets 6. That is, in the width direction W, the activated carbon sheet 6 is not positioned outside the position where the leak-proof wall 7 blocks urine, but is positioned in the area where urine is mainly present. Therefore, the activated carbon sheet 6 can be used widely and effectively, and the activated carbon sheet 6 can efficiently suppress the odor of urine.

本実施形態では、吸収性物品１は、外装シート９を更に備える。外装シート９は、裏面シート３の非肌側に位置する液不透過性シートである。外装シート９としては、特に制限はなく、例えば裏面シート３と同様のものが挙げられる。 In this embodiment, the absorbent article 1 further includes an exterior sheet 9. The exterior sheet 9 is a liquid-impermeable sheet located on the non-skin side of the back sheet 3. There are no particular limitations on the exterior sheet 9, and examples of the exterior sheet 9 include the same sheet as the back sheet 3.

本実施形態では、吸収性物品１は、長手方向Ｌに沿って延び、幅方向Ｗに間隔を空けて並んだ、吸収性物品１を幅方向Ｗに折り畳むための複数の折り線ＦＬ１、及び、幅方向Ｗに沿って延び、長手方向Ｌに間隔を空けて並んだ、吸収性物品１を長手方向Ｌに折り畳むための複数の折り線ＦＬ２を有している。本実施形態では、吸収性物品１は、一対の折り線ＦＬ１及び一対の折り線ＦＬ２を有している。そして、吸収性物品１が包装袋（図示されず）に収納されるときに、例えば、吸収性物品１における一対の折り線ＦＬ１よりも幅方向Ｗの両外側の部分が、それぞれ幅方向Ｗの内側へ折り畳まれ、一対の折り線ＦＬ１の間の部分に重なる（幅方向Ｗに三つ折りされる）。更に、一対の折り線ＦＬ２よりも長手方向Ｌの両外側の部分が、それぞれ長手方向Ｌの内側に折り畳まれ、一対の折り線ＦＬ２の間の部分に重なる（長手方向Ｌに三つ折りされる）。 In this embodiment, the absorbent article 1 has a plurality of fold lines FL1 extending along the longitudinal direction L and spaced apart in the width direction W for folding the absorbent article 1 in the width direction W, and a plurality of fold lines FL2 extending along the width direction W and spaced apart in the longitudinal direction L for folding the absorbent article 1 in the longitudinal direction L. In this embodiment, the absorbent article 1 has a pair of fold lines FL1 and a pair of fold lines FL2. When the absorbent article 1 is stored in a packaging bag (not shown), for example, both outer parts of the absorbent article 1 in the width direction W from the pair of fold lines FL1 are folded inward in the width direction W, respectively, and overlap the part between the pair of fold lines FL1 (folded in thirds in the width direction W). Furthermore, both outer parts of the absorbent article 1 in the longitudinal direction L from the pair of fold lines FL2 are folded inward in the longitudinal direction L, respectively, and overlap the part between the pair of fold lines FL2 (folded in thirds in the longitudinal direction L).

本実施形態では、一対の防漏壁７の各々は、一対の活性炭シート６の各々の少なくとも一部と、厚さ方向Ｔに重なっている。すなわち、平面視で、一対の防漏壁７の各々が、一対の活性炭シート６の各々の少なくとも一部を（、表面シート２を介して）覆っている。そのため、吸収性物品１が折り畳まれたとき（例示：幅方向Ｗ及び長手方向Ｌに三つ折り）、吸収性物品１のうちの折り畳まれた部分における一対の活性炭シート６の各々と、当該部分が折り重なった中央非含有領域ＭＮＡとの間に、一対の防漏壁７を介在させることができる。それにより、中央非含有領域ＭＮＡの表面シート２に活性炭シート６の活性炭の粒子が付着して中央非含有領域ＭＮＡでの尿の色を確認し難くなることを抑制できる。 In this embodiment, each of the pair of leak-proof walls 7 overlaps at least a portion of each of the pair of activated carbon sheets 6 in the thickness direction T. That is, in a plan view, each of the pair of leak-proof walls 7 covers at least a portion of each of the pair of activated carbon sheets 6 (via the top sheet 2). Therefore, when the absorbent article 1 is folded (e.g., folded in three in the width direction W and the longitudinal direction L), the pair of leak-proof walls 7 can be interposed between each of the pair of activated carbon sheets 6 in the folded portion of the absorbent article 1 and the central non-containing area MNA where the portion is folded over. This can prevent activated carbon particles of the activated carbon sheet 6 from adhering to the top sheet 2 of the central non-containing area MNA, making it difficult to check the color of urine in the central non-containing area MNA.

本実施形態では、吸収性物品１は、一対の折り線ＦＬ１で幅方向Ｗに三つ折りにされる。ここで、一対の折り線ＦＬ１の各々が一対の活性炭シート６の各々よりも内側に位置していると、吸収性物品１が折り畳まれたとき、吸収性物品１における折り畳まれた一対の活性炭シート６の各々が中央非含有領域ＭＮＡに（、表面シート２を介して）厚さ方向Ｔに重なることになる。その場合、活性炭シート６の活性炭の粒子が脱落すると、表面シート２を介して中央非含有領域ＭＮＡの表面シート２に付着して、中央非含有領域ＭＮＡでの尿の色を確認し難くなるおそれがある。そこで、この吸収性物品１では、一対の折り線ＦＬ１の各々が一対の活性炭シート６の各々に重なるようにしている。そのため、吸収性物品１における折り畳まれた活性炭シート６において、中央非含有領域ＭＮＡに厚さ方向Ｔに重なる領域を低減できる。それにより、中央非含有領域ＭＮＡの表面シート２に活性炭シート６の活性炭の粒子が付着して中央非含有領域ＭＮＡの表面シート２での尿の色を確認し難くなることを抑制できる。 In this embodiment, the absorbent article 1 is folded in three in the width direction W at a pair of fold lines FL1. Here, if each of the pair of fold lines FL1 is located inside each of the pair of activated carbon sheets 6, when the absorbent article 1 is folded, each of the folded pair of activated carbon sheets 6 in the absorbent article 1 will overlap the central non-containing area MNA (through the top sheet 2) in the thickness direction T. In that case, if activated carbon particles of the activated carbon sheet 6 fall off, they may adhere to the top sheet 2 of the central non-containing area MNA through the top sheet 2, making it difficult to confirm the color of the urine in the central non-containing area MNA. Therefore, in this absorbent article 1, each of the pair of fold lines FL1 is made to overlap each of the pair of activated carbon sheets 6. Therefore, the area of the folded activated carbon sheet 6 in the absorbent article 1 that overlaps the central non-containing area MNA in the thickness direction T can be reduced. This prevents activated carbon particles from the activated carbon sheet 6 from adhering to the surface sheet 2 in the central non-containing region MNA, making it difficult to check the color of urine on the surface sheet 2 in the central non-containing region MNA.

本実施形態では、幅方向Ｗにおいて、一対の折り線ＦＬ１の各々は、一対の活性炭シート６の各々の中心よりも外側に位置している。そのため、吸収性物品１における折り畳まれた活性炭シート６において、中央非含有領域ＭＮＡに厚さ方向Ｔに重なる領域をなくすことができる。したがって、中央非含有領域に活性炭ＭＮＡの粒子が付着して中央非含有領域ＭＮＡでの尿の色を確認し難くなることを確実に抑制できる。 In this embodiment, in the width direction W, each of the pair of fold lines FL1 is located outside the center of each of the pair of activated carbon sheets 6. Therefore, in the folded activated carbon sheet 6 in the absorbent article 1, it is possible to eliminate an area that overlaps with the central non-containing region MNA in the thickness direction T. This can reliably prevent particles of activated carbon MNA from adhering to the central non-containing region, making it difficult to check the color of urine in the central non-containing region MNA.

本実施形態では、吸収性物品１は、一対の活性炭シート６と表面シート２との間に、拡散シート１２を更に備えている。拡散シート１２は、平面視で長手方向Ｌが長く、幅方向Ｗの寸法が短い略矩形状であり、幅方向Ｗ及び長手方向Ｌの大きさが、一対の活性炭シート６全体と概ね同じである。拡散シート１２としては、例えば不織布やティッシュが挙げられる。拡散シート１２により、平面方向（幅方向Ｗ及び長手方向Ｌ）に広く尿を拡散させることができる。そして、拡散シート１２は、活性炭シート６を肌側から覆っているので、活性炭の粒子の一部が活性炭シート６のシート本体から脱落したとしても、脱落した粒子が表面シート２に到達することを遮断又は抑制できる。それにより、中央非含有領域ＭＮＡに活性炭の粒子が付着して中央非含有領域ＭＮＡでの尿の色を確認し難くなることを抑制できる。 In this embodiment, the absorbent article 1 further includes a diffusion sheet 12 between the pair of activated carbon sheets 6 and the top sheet 2. The diffusion sheet 12 is substantially rectangular in shape, with a long length L and a short width W in plan view, and the size of the width W and the length L are substantially the same as the pair of activated carbon sheets 6 as a whole. Examples of the diffusion sheet 12 include nonwoven fabric and tissue. The diffusion sheet 12 can diffuse urine widely in the planar direction (width W and length L). Since the diffusion sheet 12 covers the activated carbon sheet 6 from the skin side, even if some of the activated carbon particles fall off from the sheet body of the activated carbon sheet 6, the fallen particles can be blocked or prevented from reaching the top sheet 2. This can prevent activated carbon particles from adhering to the central non-containing region MNA, making it difficult to confirm the color of the urine in the central non-containing region MNA.

本実施形態では、吸収性物品１は、拡散シート１２と表面シート２との間に、したがって、一対の活性炭シート６と表面シート２との間に、高吸水性ポリマーを含む高吸水性ポリマーシート（ＳＡＰシート）１１を更に備えている。高吸水性ポリマーシート１１は、背側部Ａ３に位置し、略矩形形状を有する。ただし、高吸水性ポリマーシート１１は、高吸水性ポリマーと、高吸水性ポリマーを内包するラップシートと、を含んでいる。高吸水性ポリマーシート１１全体に対する高吸水性ポリマーの含有量は８０質量％以上、好ましくは９０質量％以上である。ラップシートは、例えば、液透過性の不織布やティッシュが挙げられる。それにより、高吸水性ポリマーシート１１が尿を吸収して膨潤したとき、高吸水性ポリマーシート１１よりも非肌側に位置する吸収体４から発生する尿の臭気を、膨潤した高吸水性ポリマーシート１１により遮断又は抑制できる。したがって、吸収体４に存在する尿の臭気を抑制できる。 In this embodiment, the absorbent article 1 further includes a superabsorbent polymer sheet (SAP sheet) 11 containing a superabsorbent polymer between the diffusion sheet 12 and the top sheet 2, and therefore between the pair of activated carbon sheets 6 and the top sheet 2. The superabsorbent polymer sheet 11 is located in the back side portion A3 and has a substantially rectangular shape. However, the superabsorbent polymer sheet 11 includes a superabsorbent polymer and a wrap sheet containing the superabsorbent polymer. The content of the superabsorbent polymer in the entire superabsorbent polymer sheet 11 is 80% by mass or more, preferably 90% by mass or more. The wrap sheet can be, for example, a liquid-permeable nonwoven fabric or tissue. As a result, when the superabsorbent polymer sheet 11 absorbs urine and swells, the swollen superabsorbent polymer sheet 11 can block or suppress the odor of urine generated from the absorbent body 4 located on the non-skin side of the superabsorbent polymer sheet 11. Therefore, the odor of urine present in the absorbent body 4 can be suppressed.

本実施形態では、中央非含有領域ＭＮＡにおいて、すなわち、活性炭シート６の存在しない領域において、上層吸収体２１及び下層吸収体２２は、長手方向Ｌに沿って延び、厚さ方向Ｔに窪んでいるスリット１３、１４を有している。例えば、上層吸収体２１のスリット１３は、肌側から非肌側に向かって厚さ方向Ｔに窪んでおり、本実施形態では上層吸収体２１を厚さ方向Ｔに貫通する貫通孔である。スリット１３は、長手方向Ｌにおいて股間部Ａ２から腹側部Ａ１の後部までの範囲に、幅方向Ｗにおいて平面視で中央非含有領域ＭＮＡの内側の範囲に形成されており、したがって、排尿領域ＳＴＡ内に形成されている。下層吸収体２２のスリット１４は、肌側から非肌側に向かって厚さ方向Ｔに窪んでおり、本実施形態では下層吸収体２２を厚さ方向Ｔに貫通する貫通孔である。スリット１４は、長手方向Ｌ及び幅方向Ｗにおいて平面視でスリット１３の内側の範囲に形成されており、同様に、排尿領域ＳＴＡ内に形成されている。そのため、***された尿は、主にスリット１３、１４に誘導され、一対の活性炭シート６をあまり介さずに、スリット１３、１４を介して上層吸収体２１及び下層吸収体２２に素早く到達し、上層吸収体２１及び下層吸収体２２に素早く吸収され、平面方向（幅方向Ｗ及び長手方向Ｌ）に拡散できる。それゆえ、上層吸収体２１及び下層吸収体２２よりも肌側に位置する一対の活性炭シート６により、上層吸収体２１及び下層吸収体２２から発生する尿の臭気を遮断又は抑制できる。したがって、吸収体４に存在する尿の臭気を抑制できる。また、本実施形態では、スリット１３、１４の幅方向Ｗの両外側に、長手方向Ｌに沿って延び、厚さ方向Ｔに上層吸収体２１から下層吸収体２２に延びる一対のエンボス部１５を有している。したがって、尿は、長手方向Ｌや厚さ方向Ｔに素早く広く拡散でき、吸収体４に素早く吸収され得る。よって、吸収体４上に位置する活性炭シート６により尿の臭気を遮断又は抑制できる。 In this embodiment, in the central non-containing region MNA, i.e., in the region where the activated carbon sheet 6 is not present, the upper absorbent body 21 and the lower absorbent body 22 have slits 13, 14 extending along the longitudinal direction L and recessed in the thickness direction T. For example, the slit 13 of the upper absorbent body 21 is recessed in the thickness direction T from the skin side toward the non-skin side, and in this embodiment, is a through hole penetrating the upper absorbent body 21 in the thickness direction T. The slit 13 is formed in the range from the crotch portion A2 to the rear of the abdominal portion A1 in the longitudinal direction L, and in the range inside the central non-containing region MNA in the width direction W in a plan view, and is therefore formed in the urination region STA. The slit 14 of the lower absorbent body 22 is recessed in the thickness direction T from the skin side toward the non-skin side, and in this embodiment, is a through hole penetrating the lower absorbent body 22 in the thickness direction T. The slits 14 are formed in the range inside the slits 13 in the longitudinal direction L and the width direction W in a plan view, and are also formed in the urination area STA. Therefore, the excreted urine is mainly guided to the slits 13 and 14, and quickly reaches the upper absorbent body 21 and the lower absorbent body 22 through the slits 13 and 14 without passing through the pair of activated carbon sheets 6, and is quickly absorbed by the upper absorbent body 21 and the lower absorbent body 22 and can be diffused in the planar direction (width direction W and longitudinal direction L). Therefore, the pair of activated carbon sheets 6 located closer to the skin than the upper absorbent body 21 and the lower absorbent body 22 can block or suppress the odor of urine generated from the upper absorbent body 21 and the lower absorbent body 22. Therefore, the odor of urine present in the absorbent body 4 can be suppressed. In addition, in this embodiment, on both outer sides of the width direction W of the slits 13 and 14, there are a pair of embossed parts 15 that extend along the longitudinal direction L and extend from the upper absorbent body 21 to the lower absorbent body 22 in the thickness direction T. Therefore, urine can be quickly and widely diffused in the longitudinal direction L and thickness direction T, and can be quickly absorbed by the absorbent body 4. Therefore, the activated carbon sheet 6 located on the absorbent body 4 can block or suppress the odor of urine.

なお、上記の実施形態において、各数値は、以下の方法で測定できる。
シートや吸収体（上層吸収体、下層吸収体）の坪量は以下の方法で測定される。まず、シートや吸収体から所定サイズ（例示：１０ｍｍ×１０ｍｍ）の３個の試料を切り出す。次いで、切り出された３個の試料の質量を直示天秤（例示：研精工業株式会社製 電子天秤ＨＦ－３００）で測定する。そして、３個の試料の質量の平均値からシートや吸収体の単位面積当たりの質量（ｇ／ｍ2）を算出して、シートや吸収体の坪量とする。 In the above embodiment, each value can be measured by the following method.
The basis weight of the sheet or absorbent body (upper-layer absorbent body, lower-layer absorbent body) is measured by the following method. First, three samples of a given size (e.g., 10 mm x 10 mm) are cut out from the sheet or absorbent body. Next, the mass of the three cut-out samples is measured using a direct reading balance (e.g., electronic balance HF-300 manufactured by Kensei Kogyo Co., Ltd.). The mass per unit area (g/ m2 ) of the sheet or absorbent body is then calculated from the average mass of the three samples, and this is taken as the basis weight of the sheet or absorbent body.

高吸水性ポリマーの坪量は以下の方法で測定される。まず、吸収体（上層吸収体、下層吸収体）から所定サイズ（例示：５０ｍｍ×５０ｍｍ）の３個の試料を切り出す。次いで、試料の質量を測定する。続いて、試料から高吸水性ポリマー以外の資材（主にパルプ繊維）だけを注意深く取出して、その資材の質量を測定する。その後、試料の質量から資材の質量を減算して、高吸水性ポリマーの質量を算出する。ただし、質量は直示天秤（例示：研精工業株式会社製 電子天秤ＨＦ－３００）で測定する。そして、３個の試料の質量の平均値と、３個の試料における高吸水性ポリマーの質量の平均値とから、高吸水性ポリマーの単位面積当たりの質量（ｇ／ｍ2）を算出して、高吸水性ポリマーの坪量とする。 The basis weight of the superabsorbent polymer is measured by the following method. First, three samples of a given size (e.g., 50 mm x 50 mm) are cut out from the absorbent (upper absorbent, lower absorbent). Next, the mass of the samples is measured. Next, only materials other than the superabsorbent polymer (mainly pulp fibers) are carefully removed from the samples, and the mass of the materials is measured. After that, the mass of the materials is subtracted from the mass of the samples to calculate the mass of the superabsorbent polymer. However, the mass is measured with a direct reading balance (e.g., electronic balance HF-300 manufactured by Kensei Kogyo Co., Ltd.). Then, the mass per unit area of the superabsorbent polymer (g/ m2 ) is calculated from the average value of the masses of the three samples and the average value of the masses of the superabsorbent polymer in the three samples, and this is taken as the basis weight of the superabsorbent polymer.
