[Aspect 1]
An absorbent body having a longitudinal direction, a width direction, and a thickness direction, including a liquid-permeable sheet, a liquid-impermeable sheet, and an absorber disposed therebetween, and abutting on a lower abdomen of a wearer; An absorbent article comprising a warming body configured as described above,
The absorbent article has the following configuration (a) or configuration (b):
(A) the warming sensation main body includes a warming sensation imparting sheet, and the rigidity of the warming sensation imparting sheet overlapped with the warming sensation imparting sheet in the thickness direction overlaps with the heat sensation imparting sheet. Absorber of the main body, lower than the rigidity of the absorber overlapping portion overlapping in the thickness direction,
(B) the warming body holds a first warming agent, and the absorbing body holds a second warming agent;
The above absorbent article, characterized by comprising:
　人の下腹部に温感を付与することにより、種々の効果、例えば、生理痛の緩和、月経前症候群（Ｐｒｅｍｅｎｓｔｒｕａｌ　Ｓｙｎｄｒｏｍｅ）、冷え性、更年期障害等の軽減等が期待される。吸収性物品を用いて、人の下腹部に温感を付与するためには、例えば、吸収性物品の、人の下腹部に相当する部分に、温感付与シートを配置することが考えられる。 By imparting a warm feeling to the lower abdomen of humans, various effects such as relief of menstrual pain, premenstrual syndrome (Premenstrual Syndrome), chilliness, menopause and the like are expected. In order to give a warm feeling to the lower abdomen of a person using the absorbent article, for example, it is conceivable to arrange a warm feeling applying sheet on a portion of the absorbent article corresponding to the lower abdomen of the person.
　一方、人の下腹部には陰毛が存在するため、そして人が呼吸する際に、呼吸に合わせて下腹部が動くため、人の下腹部に相当する部分に、剛性の高い温感付与シートを配置すると、着用者が、吸収性物品を含む着衣の下腹部に相当する部分に硬さを感じやすい傾向がある。それにより、着用者が、吸収性物品を含む着衣の下腹部部分に違和感を覚えるとともに、着用者が、下腹部に痒みを覚えやすくなる。また、着用者が、吸収性物品を含む着衣の下腹部部分に違和感を覚えることにより、着用者が、下腹部を意識する頻度が増え、陰毛と、温感付与シートとの接触等により生じた下腹部の弱い痒みであっても、着用者が気づきやすく、着用者が下腹部に不快感を覚えやすくなる。 On the other hand, since there is pubic hair in the lower abdomen of the person, and when the person breathes, the lower abdomen moves in accordance with the breathing, so a highly rigid heat-giving sheet is applied to the part corresponding to the lower abdomen of the person. When it is arranged, the wearer tends to feel hardness at a portion corresponding to the lower abdomen of the garment including the absorbent article. As a result, the wearer feels discomfort in the lower abdomen portion of the clothing including the absorbent article, and the wearer easily feels itching in the lower abdomen. In addition, the wearer felt a sense of discomfort in the lower abdomen of the clothes including the absorbent article, so that the wearer became more conscious of the lower abdomen, and was caused by contact between the pubic hair and the warmth imparting sheet and the like. Even if itching is weak in the lower abdomen, the wearer can easily notice and the wearer can easily feel discomfort in the lower abdomen.

　本開示の吸収性物品では、温感本体及び／又は吸収本体が、吸収性物品の厚さ方向に、温感剤を保持しうる層を、上層及び下層の２層以上備える場合には、それらの層を制御することにより、温感本体及び／又は吸収本体に、オンデマンド性を付与することができる。例えば、上層としての液透過性シートと、下層としての温感付与シート、吸収体等との極性（親油性度及び親水性度）を調整することにより、吸収性物品がオンデマンド性を有することができる。 In the absorbent article of the present disclosure, when the warming sensation body and / or the absorbing body includes two or more layers, an upper layer and a lower layer, which can hold a warming agent in the thickness direction of the absorbent article. By controlling the layer, the on-demand property can be imparted to the warming body and / or the absorbing body. For example, by adjusting the polarities (the degree of lipophilicity and the degree of hydrophilicity) of the liquid-permeable sheet as the upper layer and the warmness-imparting sheet and the absorber as the lower layer, the absorbent article has on-demand properties. Can be.

In a situation in which no force is applied to the warming body and / or the absorbing body, the warming composition tends to remain in the lower layer, and when a force is applied to the warming body and / or the absorbing body, the warming composition becomes an upper layer, and This is because it becomes easier for the wearer to move.
　例えば、温感本体及び／又は吸収本体が、親水性溶媒を含む温感組成物を保持している合は、下層の親水性度が、上層の親水性度よりも高いことが好ましい。温感本体及び／又は吸収本体に力が加わらない状況下では、温感組成物が、下層に留まりやすく、温感本体及び／又は吸収本体に力が加わると、温感組成物が上層、ひいては着用者に移動しやすくなるからである。 For example, when the warming body and / or the absorbing body holds a warming composition containing a hydrophilic solvent, the lower layer preferably has a higher degree of hydrophilicity than the upper layer. In a situation in which no force is applied to the warming body and / or the absorbing body, the warming composition tends to remain in the lower layer, and when a force is applied to the warming body and / or the absorbing body, the warming composition becomes an upper layer, and This is because it becomes easier for the wearer to move.
　例えば、上層が液透過性シートである場合には、液透過性シートは、親水性又は親油性を有することができる。親水性を有する液透過性シートは、液透過性シートを構成する素材を、当技術分野で公知の親水化剤で処理する（例えば、親水化剤を塗工する、親水化剤を練り込む）ことにより形成されうる。上記親水化剤としては、例えば、アルキルホスフェートエステル塩、アルキルホスフェート金属塩等が挙げられる。また、上記親水化剤としては、例えば、炭素数が１０～３０のアルキルホスフェートエステル塩と、炭素数が１０～３０のベタイン化合物、硫酸エステル塩又はスルホネート塩との混合物、アルキルホスフェートエステル塩とポリエーテル変性シリコーンとの混合物等が挙げられる。 For example, when the upper layer is a liquid permeable sheet, the liquid permeable sheet can have hydrophilicity or lipophilicity.

　本願発明者は、温感剤を含む吸収性物品では、温熱感知時間が、発熱剤（例えば、鉄粉）を含む発熱物品と比較して長くなる傾向にあり、当該温熱感知時間の間に、着用者が痒みを覚えやすいことに加え、温感剤を含む吸収性物品では、発熱剤（例えば、鉄粉）を含む発熱物品と比較して、着用者の肌の状態（例えば、着用者の肌の乾燥度等）によって、温感の覚え方に差があることを見出した。例えば、着用者の肌が水分で湿潤している場合には、着用者の肌が乾燥している場合と比較して、着用者の肌の主に角質層が膨潤した状態を保持しやすく、温感剤が、主に角化細胞（ケラチノサイト）に存在するＴＲＰチャネルに到達しやすくなるため、温感を覚えやすい（温熱感知時間が短い）。 The inventor of the present application has found that, in an absorbent article containing a warming sensation agent, the heat sensing time tends to be longer than that of a heating article containing a heating agent (eg, iron powder). In addition to the wearer's ease of remembering itching, the absorbent article containing the warming sensation agent has a skin condition of the wearer (such as the wearer's skin) as compared to the heating article containing the heating agent (eg, iron powder). Depending on the degree of dryness of the skin, etc.). For example, when the wearer's skin is moistened with moisture, it is easier to maintain a state in which mainly the stratum corneum of the wearer's skin is swollen compared to the case where the wearer's skin is dry, Since the warming agent easily reaches the TRP channel mainly present in keratinocytes (keratinocytes), the warming feeling is easily remembered (the heat sensing time is short).

　補助シート２１４の厚さは、吸収体２１１の厚さよりも薄い。そうすることにより、着用者が、下腹部に違和感を覚えにくくなる。 The thickness of the auxiliary sheet 214 is smaller than the thickness of the absorber 211. This makes it difficult for the wearer to feel uncomfortable in the lower abdomen.
　温感本体２０９は、補助シート２１４と、厚さ方向Ｔに重複する温感本体中央部２２３と、補助シート２１４と、厚さ方向Ｔに重複しない温感本体周縁部２２５とに区画され、温感本体周縁部２２５の剛性が、温感本体中央部２２３の剛性よりも低い。そうすることにより、吸収性物品の使用時に、着用者が、下腹部に違和感を覚えにくい。 The warming body 209 is divided into an auxiliary sheet 214, a warming body central portion 223 overlapping in the thickness direction T, an auxiliary sheet 214, and a warming body peripheral edge 225 not overlapping in the thickness direction T. The rigidity of the sensation main body peripheral edge portion 225 is lower than the stiffness of the warm sensation main body central portion 223. By doing so, the wearer is less likely to feel discomfort in the lower abdomen when using the absorbent article.

The “first warming composition” that can be held by the main body and the “second warming composition” that can be held by the absorbing body may be collectively referred to as “warming composition”.
　本開示の吸収性物品、すなわち、構成（ｂ）を備える吸収性物品に関する一般記載、例えば、温感体（第１温感剤及び第２温感剤）、並びに温感組成物（第１温感組成物及び第２温感組成物）に関する一般記載は、構成（ａ）を備える吸収性物品の箇所で説明されるものと同様であるため説明を省略し、ここでは、構成（ａ）を備える吸収性物品と異なる点を中心に説明する。
　なお、構成（ａ）を備える吸収性物品を引用する場合において、「温感付与シート」及び「温感付与シート重複部分」は、適宜、「補助シート」及び「補助シート重複部分」と読み替える。 General description about the absorbent article of the present disclosure, that is, the absorbent article having the configuration (b), for example, a warming body (first warming agent and second warming agent), and a warming composition (first warming composition) The general description about the photosensitive composition and the second warming composition) is the same as that described in the section of the absorbent article having the configuration (a), and thus the description is omitted, and the configuration (a) is described here. The following description focuses on the differences from the provided absorbent article.
In addition, in quoting the absorbent article having the configuration (a), the terms "warmness imparting sheet" and "warmness imparting sheet overlapping portion" are appropriately read as "auxiliary sheet" and "auxiliary sheet overlapping portion".
　本開示の吸収性物品では、温感本体は、吸収性物品の平面方向（吸収性物品の長手方向及び幅方向）において、第１温感剤を、任意の位置、例えば、全面、中央部等に保持することができる。本開示の吸収性物品において、温感本体が補助シートを備える場合には、温感本体は、補助シートと、吸収性物品の厚さ方向に重複する領域、補助シートと、吸収性物品の厚さ方向に重複する領域及び重複しない領域に保持することができる。 In the absorbent article according to the present disclosure, the warming sensation body is configured such that the first warming sensate is placed at an arbitrary position, for example, the entire surface, the center, or the like, in the planar direction of the absorbent article (the longitudinal direction and the width direction of the absorbent article). Can be held. In the absorbent article of the present disclosure, when the warming main body includes the auxiliary sheet, the warming main body includes the auxiliary sheet, an area overlapping in the thickness direction of the absorbent article, the auxiliary sheet, and the thickness of the absorbent article. It can be held in an area that overlaps in the vertical direction and an area that does not overlap.
　本開示の吸収性物品では、温感本体は、吸収性物品の厚さ方向において、第１温感剤を、任意の位置に保持することができる。本開示の吸収性物品において、温感本体が、液透過性シート及び液不透過性シートを備えている場合には、温感本体は、第１温感剤を、液透過性シート及び液不透過性シートの間、液透過性シートの内部等に保持することができる。また、本開示の吸収性物品において、温感本体が、液透過性シート、補助シート及び液不透過性シートを備えている場合には、温感本体は、第１温感剤を、液透過性シートの内部、補助シートの内部、液透過性シート及び補助シートの間、補助シート及び液不透過性シートの間、並びにそれらの任意の組み合わせの位置に保持することができる。 で は In the absorbent article of the present disclosure, the warming sensation body can hold the first warming sensate at an arbitrary position in the thickness direction of the absorbent article. In the absorbent article according to the present disclosure, when the warm sensation body includes the liquid permeable sheet and the liquid impermeable sheet, the warm sensation body includes the first warming agent in the liquid permeable sheet and the liquid impermeable sheet. Between the permeable sheets, it can be held inside the liquid permeable sheet or the like. Further, in the absorbent article according to the present disclosure, when the warm sensation main body includes a liquid permeable sheet, an auxiliary sheet, and a liquid impermeable sheet, the warm sensation main body includes a liquid permeable sheet, The inside of the permeable sheet, the inside of the auxiliary sheet, between the liquid-permeable sheet and the auxiliary sheet, between the auxiliary sheet and the liquid-impermeable sheet, and any combination thereof can be held.
　本開示の吸収性物品では、吸収本体は、第２温感剤を、吸収体と、吸収性物品の厚さ方向に重複する領域、吸収体と、吸収性物品の厚さ方向に重複しない領域等に保持することができる。吸収本体が、第２温感剤を、吸収体と、吸収性物品の厚さ方向に重複する領域に保持していると、着用者の皮膚（***口等）と直接接している機会の多い吸収体から、第２温感剤を着用者の皮膚に浸透させやすくなる。また、吸収本体が、第２温感剤を、吸収体と、吸収性物品の厚さ方向に重複しない領域等に保持することにより、着用者の肌の水分率が高く、第２温感剤が浸透しやすい部分（着用者の皮膚のうち、吸収体と接していない部分は、吸収体による水分の吸収が少なく、着用者の肌の水分率が高くなりやすい）に、第２温感剤を浸透させやすくなる。 In the absorbent article according to the present disclosure, the absorbent main body includes the second warming sensation agent, a region overlapping the absorber and the thickness direction of the absorbent article, and a region not overlapping the absorber and the thickness direction of the absorbent article. Etc. can be held. When the absorbent main body holds the second warming sensate in an area overlapping with the absorbent body in the thickness direction of the absorbent article, there are many chances that the absorbent body is in direct contact with the wearer's skin (eg, excretory opening). It becomes easy for the second warming agent to permeate the wearer's skin from the absorber. In addition, the absorption main body holds the second warming agent in an area that does not overlap with the absorbent body in the thickness direction of the absorbent article, so that the moisture content of the wearer's skin is high, (A portion of the wearer's skin that is not in contact with the absorber tends to absorb less moisture by the absorber and increase the moisture content of the wearer's skin). Makes it easier to penetrate.
　本開示の吸収性物品では、吸収本体は、第２温感剤を、吸収本体の***口当接域、***口当接域の、吸収性物品の幅方向の両外側に存在する***口当接域隣接領域、***口当接域の、吸収性物品の長手方向の両外側に存在する***口当接域隣接領域等に保持することができる。吸収本体が、第２温感剤を、***口当接域及び／又は***口当接域隣接領域に保持することにより、着用者の下腹部に温感を付与しやすくなり、ひいては、着用者が下腹部に温感を覚えにくくなる。 In the absorbent article according to the present disclosure, the absorbent main body includes the second warming sensate in the excretion opening contact area of the absorbent main body, the excretion opening existing on both outer sides of the absorbent article in the width direction of the absorbent article. It can be held in the excretion port contact area adjacent to the excretion port contact area existing on both sides of the absorbent article in the longitudinal direction of the absorbent article. The absorption main body holds the second warming agent in the excretion opening contact area and / or the excretion opening contact area adjacent area, so that it is easy to give a warm feeling to the lower abdomen of the wearer, and thus, the wearer However, the lower abdomen becomes difficult to feel warmth.
　本開示の吸収性物品では、吸収本体は、吸収性物品の厚さ方向において、第２温感剤を、液透過性シートの内部、吸収体の内部、液透過性シート及び吸収体の間、吸収体及び液不透過性シートの間、液透過性シート及び液不透過性シートの間、並びにそれらの任意の組み合わせの位置に保持することができる。 In the absorbent article according to the present disclosure, the absorbent main body includes, in the thickness direction of the absorbent article, the second warming agent inside the liquid-permeable sheet, inside the absorber, between the liquid-permeable sheet and the absorber, It can be held between the absorber and the liquid-impermeable sheet, between the liquid-permeable sheet and the liquid-impermeable sheet, and any combination thereof.
　本開示の吸収性物品では、温感本体の補助シートと、吸収性物品の厚さ方向に重複する補助シート重複部分の剛軟度が、吸収本体の吸収体と、吸収性物品の厚さ方向に重複する吸収体重複部分の剛軟度よりも低いことが好ましく、そして補助シート重複部分の剛軟度が吸収体重複部分の剛軟度の、より好ましくは５～７０％、さらに好ましくは１０～６０％、そしてさらにいっそう好ましくは２０～５０％の範囲にある。そうすることにより、着用者が吸収性物品を着用する際に、補助シート重複部分が折れ曲がりにくく、ひいては着用者の下腹部に的確に温感を覚えさせることができるとともに、着用者の下腹部に違和感を覚えさせにくくなる。 In the absorbent article of the present disclosure, the softness of the auxiliary sheet of the warm body and the auxiliary sheet overlapping portion overlapping in the thickness direction of the absorbent article are different from those of the absorbent body of the absorbent body and the thickness direction of the absorbent article. It is preferable that the softness of the overlapping portion of the absorber is lower than the softness of the overlapping portion of the absorber, and more preferably 5 to 70%, even more preferably 10 to 70% of the softness of the overlapping portion of the absorber. ～ 60%, and even more preferably in the range of 20-50%. By doing so, when the wearer wears the absorbent article, the auxiliary sheet overlapping portion is less likely to bend, and thus the lower abdomen of the wearer can be properly warmed, and the lower abdomen of the wearer It is difficult to make the user feel uncomfortable.
　本開示の吸収性物品では、温感本体の補助シート重複部分の剛軟度は、好ましくは１～１５ｍＮ、より好ましくは３～１０ｍＮ、そしてさらに好ましくは４～８ｍＮである。着用者の下腹部に的確に温感を覚えさせることができるとともに、着用者の下腹部に違和感を覚えさせにくくする観点からである。 で は In the absorbent article of the present disclosure, the stiffness of the overlapping portion of the auxiliary sheet of the warm sensation body is preferably 1 to 15 mN, more preferably 3 to 10 mN, and still more preferably 4 to 8 mN. This is from the viewpoint that the lower abdomen of the wearer can be made to accurately feel warmth and that the lower abdomen of the wearer is less likely to feel uncomfortable.
　上記剛軟度の関係は、補助シート重複部分の、吸収性物品の長手方向及び幅方向の中心を中心としたサンプル（以下、剛軟度の測定方法を参照）と、吸収体重複部分の、***口当接域の中心を中心としたサンプルとの間で満たすことが好ましく、そして補助シート重複部分の任意の部分におけるサンプルと、吸収体重複部分の任意の部分におけるサンプルとの間で満たすことがより好ましい。 The relationship between the softness and softness of the absorbent sheet is defined by a sample centered on the center of the absorbent article in the longitudinal direction and the width direction (hereinafter, referred to as a method of measuring the softness) and an overlapping portion of the absorber. It is preferable to fill between the sample centered on the center of the excretion abutment area, and between the sample at any part of the auxiliary sheet overlap part and the sample at any part of the absorber overlap part. Is more preferred.
　また、吸収体が、吸収コア（パルプ繊維、パルプ繊維及び高吸水性ポリマーの混合物、高吸水性ポリマーシート等）と、コアラップ（ティッシュ、エアレイドパルプ等）とを含む場合には、上記剛軟度の関係は、吸収体重複部分のうち、吸収コアと、吸収性物品の厚さ方向に重複する吸収コア重複部分において満たすことが好ましい。着用者が硬さを覚えやすいのは、吸収体の吸収コアの部分だからである。 When the absorbent includes an absorbent core (pulp fibers, a mixture of pulp fibers and a superabsorbent polymer, a superabsorbent polymer sheet, etc.) and a core wrap (tissue, air-laid pulp, etc.), Is preferably satisfied in the absorbent core overlapping portion of the absorbent core overlapping portion overlapping in the thickness direction of the absorbent article. The wearer can easily remember the hardness because of the absorbent core portion of the absorber.
　さらに、上記剛軟度の関係は、吸収性物品の幅方向において満たすことが好ましく、そして吸収性物品の長手方向及び幅方向の両方で満たすことが好ましい。着用者の下腹部に違和感を覚えさせにくくする観点からである。剛軟度の測定方法については、構成（ａ）に関して説明済であるため、ここでの説明は省略する。 Furthermore, it is preferable that the above-mentioned rigidity relation is satisfied in the width direction of the absorbent article, and it is preferable that the relation is satisfied in both the longitudinal direction and the width direction of the absorbent article. This is from the viewpoint of making it difficult for the lower abdomen of the wearer to feel uncomfortable. Since the method of measuring the bending resistance has already been described with respect to the configuration (a), the description is omitted here.
　本開示の吸収性物品では、補助シートの厚さが、吸収体の厚さよりも薄いことが好ましく、そして補助シートの厚さが、吸収体の厚さの、より好ましくは１～６０％、さらに好ましくは２～５０％、そしてさらにいっそう好ましくは３～４０％の範囲にある。そうすることにより、着用者の下腹部に温感を覚えさせることができるとともに、着用者の下腹部に違和感を覚えさせにくくなる。
　なお、温感シート及び吸収体の厚さは、上述の繊維密度の測定における、サンプル片の厚さと同様に測定する。 In the absorbent article of the present disclosure, it is preferable that the thickness of the auxiliary sheet is smaller than the thickness of the absorber, and the thickness of the auxiliary sheet is more preferably 1 to 60% of the thickness of the absorber, furthermore Preferably it is in the range of 2-50%, and even more preferably 3-40%. By doing so, it is possible to make the lower abdomen of the wearer feel warm, and it is difficult to make the lower abdomen of the wearer feel uncomfortable.
In addition, the thickness of a warm feeling sheet and an absorber is measured similarly to the thickness of a sample piece in the above-mentioned fiber density measurement.
　本開示の吸収性物品では、温感本体が、補助シートと、吸収性物品の厚さ方向に重複する温感本体中央部（すなわち、補助シート重複部分）と、補助シートと、吸収性物品の厚さ方向に重複しない温感本体周縁部とに区画されるとともに、温感本体周縁部の剛性が、温感本体中央部の剛性よりも低いことが好ましい。そうすることにより、吸収性物品の使用時に、着用者の下腹部に違和感を覚えさせにくくなる。
　なお、上記剛性の高低は、温感本体中央部と、温感本体周縁部とに触れることにより判断することができる。 In the absorbent article of the present disclosure, the warming sensation body includes the auxiliary sheet, the central part of the warming sensation body that overlaps in the thickness direction of the absorbent article (that is, the auxiliary sheet overlapping portion), the auxiliary sheet, and the absorbent sheet. It is preferable that the rigid body is divided into a peripheral portion of the thermal sensation body that does not overlap in the thickness direction, and that the rigidity of the peripheral portion of the thermal sensation body is lower than the rigidity of the central portion of the thermal sensation body. This makes it difficult for the wearer to feel uncomfortable at the lower abdomen when using the absorbent article.
The level of the rigidity can be determined by touching the central part of the main body and the peripheral part of the main body.
　本開示の吸収性物品では、温感本体が、補助シートを備えることができ、上記補助シートの素材としては、液透過性シートの素材として列挙されるものが挙げられる。
　上記補助シートは、好ましくは１０～２００ｇ／ｍ2、そしてより好ましくは１５～１５０ｇ／ｍ2の坪量を有する。 In the absorbent article of the present disclosure, the warming sensation body can include an auxiliary sheet, and examples of the material of the auxiliary sheet include those listed as a material of the liquid-permeable sheet.
The auxiliary sheet preferably has a basis weight of 10 to 200 g / m 2 , and more preferably 15 to 150 g / m 2 .
　以下、例を挙げて本開示を説明するが、本開示はこれらの例に限定されるものではない。
