Description

本発明は、生理用ナプキンや失禁パッド、おむつなどの吸収性物品に関する。   The present invention relates to absorbent articles such as sanitary napkins, incontinence pads, and diapers.

生理用ナプキン等の吸収性物品において、***液が多いときや長時間使用するときなどにムレやべたつきが生じて着用者が不快に感じることがある。これに対し、従来、清涼剤等の冷感剤を吸収性物品に含有させることによって、着用感の向上をはかろうとする技術があった（例えば特許文献１及び２）。冷感剤は揮発して、着用者の肌の感覚神経細胞のＴＲＰＭ８やＴＲＰＡ１などを刺激して受容器のしきい値を変化させることで清涼感が感じられる。特許文献２記載の吸収性物品は、冷感材が***によって消耗されるという問題に対応するため、着用者の***部に当接する領域における冷感材料の量を、それ以外の領域よりも多くしている。   In an absorbent article such as a sanitary napkin, the wearer may feel uncomfortable due to stuffiness or stickiness when there is a lot of excreted liquid or when used for a long time. On the other hand, there has heretofore been a technique for improving the feeling of wearing by incorporating a cooling agent such as a refreshing agent into the absorbent article (for example, Patent Documents 1 and 2). The cooling sensation volatilizes and stimulates TRPM8, TRPA1, etc. of the sensory nerve cells of the wearer's skin to change the threshold value of the receptor, thereby providing a refreshing feeling. In the absorbent article described in Patent Document 2, in order to cope with the problem that the cooling sensation material is consumed by excretion, the amount of the cooling sensation material in the region contacting the excretion part of the wearer is larger than that in the other regions. doing.

発明の詳細な説明Detailed Description of the Invention

本発明は、着用者の肌に対する適度な冷感効果を長く効果的に維持する吸収性物品に関する。   The present invention relates to an absorbent article that maintains a moderate cooling effect on the skin of a wearer for a long time and effectively.

吸収性物品における冷感剤の含有量は揮発によって時間の経過とともに低減し、清涼効果は薄らいでいく。しかし、特許文献２記載の吸収性物品のように単に冷感材の量を増やしては、肌への刺激が強くなり過ぎ、却って着用感を損ねかねない。   The content of the cooling agent in the absorbent article is reduced with the lapse of time due to volatilization, and the cooling effect is diminished. However, if the amount of the cooling sensation material is simply increased as in the absorbent article described in Patent Document 2, irritation to the skin becomes too strong, and the feeling of wearing may be impaired.

これに対し、本発明に係る吸収性物品は、着用者の肌に対する適度な冷感効果を長く効果的に維持することができる。   On the other hand, the absorbent article which concerns on this invention can maintain the moderate cooling sensation effect with respect to a wearer's skin long and effectively.

以下、本発明に係る吸収性物品の好ましい一実施形態としての生理用ナプキン（以下、ナプキンとも言う）１０について、図面を参照しながら説明する。
本発明においては、特に断らない限り、人体に接触する側を肌面側ないし肌当接面側あるいは表面側といい、これと反対側を非肌面側ないし非肌当接面側あるいは裏面側という。これらは、人体に接触する面を有さない部材に関しても、吸収性物品の部材構成における相対的な位置関係を示す用語として用いる。また、着用時に人体の前側に位置する方向を前方といい、後側に位置する方向を後方という。吸収性物品の表面又は裏面の法線方向を厚み方向という。Hereinafter, a sanitary napkin (hereinafter also referred to as a napkin) 10 as a preferred embodiment of an absorbent article according to the present invention will be described with reference to the drawings.
In the present invention, unless otherwise specified, the side in contact with the human body is referred to as the skin surface side or the skin contact surface side or the surface side, and the opposite side is referred to as the non-skin surface side or the non-skin contact surface side or the back surface side. That's it. These are also used as terms indicating a relative positional relationship in the member configuration of the absorbent article even with respect to a member that does not have a surface in contact with the human body. Moreover, the direction located in the front side of a human body at the time of wear is called front, and the direction located in a rear side is called back. The normal direction of the front surface or the back surface of the absorbent article is referred to as the thickness direction.

ナプキン１０は、図１及び２に示すように、肌当接面側の表面層１と、表面層１の非肌当接面側に位置する液保持性の吸収層３とを有する。本実施形態においては、吸収層３の非肌当接面側に裏面層２が配されている。表面層１は液を吸収層３へと送り込む液透過性を備え、裏面層２は吸収層３にある液に対する防漏性を備える。表面層１及び裏面層２は吸収層３の両面を覆いつつ、吸収層３の外縁外方へと延出する大きさを有する。さらに表面層１と吸収層３との間には、液拡散性を備える中間繊維層４を有する。また、表面層１の肌当接面側の両側にサイドシート５が積層されている。サイドシート５と裏面層２とが吸収層３の幅方向外方に延出して、着衣等への固定手段であるウイング部６を形成している。ウイング部６及び裏面層２の非肌当接面側には、ナプキン１０を着衣に固定するための粘着部（図示せず）を有している。このシートの積層構造において、ナプキン１０の外周縁は、吸収層３を介在させずに接合された外周シール部９となっている。   As shown in FIGS. 1 and 2, the napkin 10 includes a surface layer 1 on the skin contact surface side and a liquid-retaining absorbent layer 3 positioned on the non-skin contact surface side of the surface layer 1. In the present embodiment, the back layer 2 is disposed on the non-skin contact surface side of the absorbent layer 3. The surface layer 1 has a liquid permeability for sending the liquid to the absorption layer 3, and the back surface layer 2 has a leak-proof property for the liquid in the absorption layer 3. The surface layer 1 and the back surface layer 2 have a size that extends outward from the outer edge of the absorbent layer 3 while covering both surfaces of the absorbent layer 3. Further, an intermediate fiber layer 4 having liquid diffusibility is provided between the surface layer 1 and the absorbent layer 3. Further, side sheets 5 are laminated on both sides of the surface layer 1 on the skin contact surface side. The side sheet 5 and the back surface layer 2 extend outward in the width direction of the absorbent layer 3 to form a wing portion 6 that is a fixing means for clothes or the like. On the non-skin contact surface side of the wing part 6 and the back surface layer 2, there is an adhesive part (not shown) for fixing the napkin 10 to the clothes. In the laminated structure of the sheet, the outer peripheral edge of the napkin 10 is an outer peripheral seal portion 9 joined without the absorbent layer 3 interposed.

ナプキン１０は、他の構成部材を含んでいてもよく、また中間繊維層４、サイドシート５を有さない形態であってもよい。さらに表面層１から吸収層３にかけて圧搾した防漏溝、表面層１上の複数のエンボスなどを有していてもよい。また、サイドシート５は、表面層１と接合されながら、表面層１の両側よりも内方側に自由端部を残すようにしてもよく、前記自由端部に弾性部材等を配して防漏カフを構成してもよい。   The napkin 10 may include other constituent members, and may have a form without the intermediate fiber layer 4 and the side sheet 5. Furthermore, you may have the leak-proof groove compressed from the surface layer 1 to the absorption layer 3, the some embossing on the surface layer 1, etc. Further, the side sheet 5 may be bonded to the surface layer 1 while leaving a free end portion on the inner side of both sides of the surface layer 1, and an elastic member or the like is disposed on the free end portion to prevent the side sheet 5. A leak cuff may be configured.

ナプキン１０は、平面視において、縦方向（Ｙ方向）と、該縦方向と直交する幅方向（Ｘ方向）とを有する、縦長形状である。また表面層１、裏面層２及び吸収層３は、ナプキン１０と同様に、縦長形状である。縦方向は、ナプキン１０の装着時における、着用者の腹側部、股下部及び背側部を繋ぐ方向に対応する。幅方向は、着用者の股下における左右の足を繋ぐ方向に対応する。本明細書において、縦方向（Ｙ方向）及び幅方向（Ｘ方向）は、ナプキン１０の平面視における方向を示すと同時に、表面層１、裏面層２及び吸収層３の平面視における方向を示す。   The napkin 10 has a vertically long shape having a longitudinal direction (Y direction) and a width direction (X direction) orthogonal to the longitudinal direction in plan view. Similarly to the napkin 10, the front surface layer 1, the back surface layer 2, and the absorption layer 3 have a vertically long shape. The vertical direction corresponds to a direction connecting the wearer's abdomen, crotch, and back side when the napkin 10 is worn. The width direction corresponds to the direction connecting the left and right feet in the wearer's crotch. In the present specification, the vertical direction (Y direction) and the width direction (X direction) indicate directions in the plan view of the napkin 10 and simultaneously indicate directions in the plan view of the surface layer 1, the back surface layer 2, and the absorption layer 3. .

ナプキン１０は、縦方向に関して、着用者の***ポイントに対応する領域を含む中間部Ｃを有する。さらに、中間部Ｃよりも前方の下腹部側に配置される前方部Ｆ、後方の臀部側に配置される後方部Ｒを有する。また、中間部Ｃには、幅方向中央部分に、前記***ポイントに対向し、***液を直接受け止める受液領域Ｃ１がある。受液領域Ｃ１がある「幅方向中央部分」とは、図１及び３に示すように、幅方向の中心線Ｌから左右に広がる所定幅の範囲をいい、吸収層の幅方向両端縁３９よりも内側の範囲の部分を言う。具体的は、ナプキン１０の幅方向の中心線Ｌから左右に広がる領域であって、吸収層幅に対して４０％以上６０％以下の範囲の部分をいう。なお、中間部Ｃ、受液領域Ｃ１、前方部Ｆ及び後方部Ｒは、ナプキン１０における区分を示すと同時に、これに対応する表面層１、吸収層３及び裏面層２における区分をも示す。   The napkin 10 has the intermediate part C including the area | region corresponding to a wearer's excretion point regarding a vertical direction. Furthermore, it has the front part F arrange | positioned at the front lower abdomen side rather than the intermediate part C, and the rear part R arrange | positioned at the back collar side. In addition, the intermediate part C has a liquid receiving area C1 at the central part in the width direction that faces the excretion point and directly receives the excretion liquid. As shown in FIGS. 1 and 3, the “width direction central portion” where the liquid receiving region C1 is located means a range of a predetermined width extending from the center line L in the width direction to the left and right. Also say the part of the inner range. Specifically, it is a region extending from the center line L in the width direction of the napkin 10 to the left and right, and refers to a portion in the range of 40% to 60% with respect to the absorption layer width. The intermediate portion C, the liquid receiving region C1, the front portion F, and the rear portion R indicate sections in the napkin 10, and also indicate sections in the surface layer 1, the absorption layer 3, and the back layer 2 corresponding thereto.

中間部Ｃ、前方部Ｆ及び後方部Ｒの区分位置は、使用目的等によって設定される吸収性物品の長さに応じて適宜設定され得る。ショーツの股下部に折り曲げて固定するウイング部を備える場合は、該ウイング部の存在する縦方向に沿った領域が中間部Ｃとなる。本実施形態のナプキン１０は、昼用などとして設定される形状の例を示しており、縦方向の長さを３等分して、前方部Ｆ、中間部Ｃ及び後方部Ｒが設定されており、ウイング部を備えない昼用のナプキンの場合には、中間部はこの設定に従う。ナプキン１０がどのような形状であっても一般的には、中間部Ｃは、前方部Ｆからの一定の距離の位置にある部位として設定され得る。さらに大人用若しくは幼児用のおむつなど、また、尿取りパッドなどについては、縦方向の長さを３等分して、前方部Ｆ、中間部Ｃ及び後方部Ｒが設定される。   The division positions of the intermediate part C, the front part F, and the rear part R can be appropriately set according to the length of the absorbent article set according to the purpose of use or the like. When the wing part which bends and fixes to the crotch part of shorts is provided, the area | region along the vertical direction in which this wing part exists becomes the intermediate part C. FIG. The napkin 10 of the present embodiment shows an example of a shape set for daytime, etc., and the front part F, the intermediate part C, and the rear part R are set by dividing the length in the vertical direction into three equal parts. In the case of a daytime napkin without a wing part, the intermediate part follows this setting. In general, the intermediate part C can be set as a part at a certain distance from the front part F regardless of the shape of the napkin 10. Further, for an adult or infant diaper, a urine collection pad, and the like, a front portion F, an intermediate portion C, and a rear portion R are set by dividing the longitudinal length into three equal parts.

次に、ナプキン１０が有する冷感剤及び吸収層３の分断部８について説明する。   Next, the cooling agent which the napkin 10 has and the parting part 8 of the absorption layer 3 will be described.

冷感剤を含む領域が、吸収層３又は吸収層３よりも表面層１側の部材に配されている。冷感剤は、揮発して、着用者の皮膚及び／又は粘膜表面の温度受容器を刺激して、皮膚及び／又は粘膜表面上の温度を変化させる必要なしに、着用者に冷感、爽快感を感じさせることができる剤である。冷感剤を含む領域は、着用者の肌に対する適度な冷感効果を長く効果的に維持させる観点から、表面層１よりも非肌当接面側にあることが好ましい。このとき、表面層１に冷感剤が含まれる態様を排除するものではなく、冷感剤の含有量が最も多い領域が表面層１よりも非肌面側にあることが好ましい。また、冷感剤を含む領域は、ナプキン１０の平面視において、中間部Ｃにあることが好ましい。   The region containing the cooling sensation agent is disposed on the absorption layer 3 or the member closer to the surface layer 1 than the absorption layer 3. Cooling agents volatilize and stimulate the wearer's skin and / or mucosal surface temperature receptors to change the temperature on the skin and / or mucosal surface without the need to change the temperature on the skin and / or mucosal surface. It is an agent that can make you feel. The region containing the cooling sensation agent is preferably located on the non-skin contact surface side of the surface layer 1 from the viewpoint of effectively maintaining a moderate cooling sensation effect on the wearer's skin for a long time. At this time, the aspect in which the cooling agent is included in the surface layer 1 is not excluded, and it is preferable that the region having the highest content of the cooling agent is on the non-skin surface side of the surface layer 1. In addition, the region containing the cooling sensation agent is preferably in the intermediate portion C in the plan view of the napkin 10.

冷感剤を含む、吸収層３よりも表面層１側の部材としては、例えば、中間繊維層４や、図示しないが吸収層３の肌当接面側を被覆する液透過性のシートなどが挙げられる。   Examples of the member including the cooling sensation agent on the surface layer 1 side of the absorbent layer 3 include an intermediate fiber layer 4 and a liquid-permeable sheet that covers the skin contact surface side of the absorbent layer 3 (not shown). Can be mentioned.

冷感剤が吸収層３に含まれる場合、吸収層３のいずれの部位に含まれてもよい。ただし、後述の分断部８による空気の動きに連動した冷感剤の揮発成分の肌への効果的な移動を考慮すると、冷感剤が吸収層３の肌面側に含まれていることが好ましい。ここで言う「吸収層３の肌面側」とは、吸収層３の厚みを２等分した場合の肌面側の領域をいう。この場合、吸収層３の肌面側に冷感剤が含まれていれば、非肌面側に冷感剤が含まれていてもよい。吸収層３の肌面側において、冷感剤の含有量が非肌面側よりも相対的に多い領域があることがより好ましい。冷感剤の含有量が相対的に多い領域は、吸収層３の肌面側であれば、肌面側の最表面に無くてもよい。なお、吸収層３に冷感剤が含まれる場合、吸収層３よりも表面層１側の部材に冷感剤が含まれていてもよく、含まれていなくてもよい。   When the cooling sensation agent is included in the absorption layer 3, it may be included in any part of the absorption layer 3. However, in consideration of effective movement of the volatile components of the cooling sensate to the skin in conjunction with the movement of air by the dividing portion 8 described later, the cooling sensation agent may be included on the skin surface side of the absorbent layer 3. preferable. The “skin surface side of the absorbent layer 3” here refers to a region on the skin surface side when the thickness of the absorbent layer 3 is divided into two equal parts. In this case, as long as a cooling sensation agent is included on the skin surface side of the absorbent layer 3, the cooling sensation agent may be included on the non-skin surface side. More preferably, on the skin surface side of the absorbent layer 3, there is a region where the content of the cooling sensation agent is relatively larger than that on the non-skin surface side. The region having a relatively high content of the cooling sensation agent may be absent on the outermost surface on the skin surface side as long as it is on the skin surface side of the absorbent layer 3. In addition, when the cooling sensation agent is contained in the absorption layer 3, the cooling sensation agent may be contained in the member of the surface layer 1 side rather than the absorption layer 3, and it does not need to be contained.

吸収層３においては、冷感剤が、吸収層３の肌面側であって、該肌面側の幅方向両端縁３９よりも内側の領域に含まれることが好ましい。
これにより、ナプキン１０の内部において冷感剤を長持ちさせ、着用者の鼠蹊部など肌の敏感な部分への刺激を抑制しつつ、後述の分断部８の作用による肌への冷感付与をより確実に行うことができる。この観点から、吸収層３の「肌面側の幅方向両端縁３９よりも内側の領域」とは、着用者の肌の鼠蹊部の付近を避けた領域を言う。具体的には、幅方向の両端縁３９を含まずに幅方向の中心線Ｌから左右に広がる領域であって、吸収層幅に対して７５％以下の範囲の領域であることが好ましく、吸収層幅に対して６０％以下の範囲の領域であることがより好ましい。In the absorption layer 3, it is preferable that the cooling sensation agent is included in a region on the skin surface side of the absorption layer 3 and on the inner side of the width direction both edges 39 on the skin surface side.
Thereby, the cooling sensation is prolonged in the inside of the napkin 10, and the cooling sensation is imparted to the skin by the action of the dividing portion 8 described later while suppressing irritation to sensitive parts of the skin such as the buttocks of the wearer. It can be done reliably. From this point of view, the “region inside the width direction both end edges 39 on the skin surface side” of the absorbent layer 3 refers to a region avoiding the vicinity of the buttocks of the wearer's skin. Specifically, it is a region that does not include both end edges 39 in the width direction and extends from the center line L in the width direction to the left and right, and is preferably a region that is 75% or less of the absorption layer width. It is more preferable that the region be in the range of 60% or less with respect to the layer width.

冷感剤を含む領域において、ナプキン１０の中間部Ｃの幅方向中央（受液領域Ｃ１）に、周囲よりも冷感剤坪量が少ない領域を有することが好ましい。
これにより、着用者の刺激に敏感な***部に対して冷感が強くなり過ぎることを抑制することができる。肌への過度な刺激を抑制する観点から、前記「冷感剤を含む領域」と該領域内の「冷感剤坪量が少ない領域」とは、表面層１に近い部材の平面方向に広がる領域であることが好ましい。例えば、中間繊維層４に冷感剤が含まれている場合、中間繊維層４の平面領域において、中間部Ｃの幅方向中央に、周囲よりも冷感剤坪量が少ない領域を有することが好ましい。また吸収層３に冷感剤が含まれている場合、吸収層３の肌面側の最表層の平面領域において、中間部Ｃの幅方向中央に、周囲よりも冷感剤坪量が少ない領域を有することが好ましい。In the region including the cooling sensation agent, it is preferable that the center of the intermediate portion C of the napkin 10 in the width direction (liquid receiving region C1) has a region having a cooling sensation basis weight smaller than that of the surrounding area.
Thereby, it can suppress that a cold feeling becomes strong too much with respect to the excretion part sensitive to a wearer's irritation | stimulation. From the viewpoint of suppressing excessive irritation to the skin, the “region containing the cooling sensate” and the “region having a low cooling sensation basis weight” in the region spread in the plane direction of the member close to the surface layer 1. A region is preferred. For example, when a cooling sensation agent is included in the intermediate fiber layer 4, in the planar region of the intermediate fiber layer 4, the middle part C may have a region having a lower basis weight of the cooling sensation agent than in the center in the width direction. preferable. Moreover, when the cooling layer is contained in the absorption layer 3, in the plane | planar area | region of the outermost layer of the skin layer side of the absorption layer 3, the area | region where the cooling agent basis weight is less than the periphery in the center of the width direction of the intermediate part C It is preferable to have.

ナプキン１０において、冷感剤は、後述する分断部８の作用によって、残存量が低減しても効果的に肌へと送り出されるため、過度に含有量を増量する必要がない。そのため従来と同様の含有量をしながら、肌への刺激を抑え、適度な冷感効果を長く効果的に維持することができる。
具体的には、ナプキン１０全体における冷感剤の含有量は、冷感をほどよく感じ、ムレやべたつく感覚を低減させる効果の観点から、例えば、乳酸メンチルの場合であれば、製品長に対して４ｍｇ／１００ｍｍ以上が好ましく、５ｍｇ／１００ｍｍ以上がより好ましく、６．５ｍｇ／１００ｍｍ以上が更に好ましい。前記含有量は、肌への刺激を抑制する観点から、１３．５ｍｇ／１００ｍｍ以下が好ましく、１２．５ｍｇ／１００ｍｍ以下がより好ましく、１１．５ｍｇ／１００ｍｍ以下が更に好ましい。
また、中間部Ｃの幅方向中央の吸収層３における表面層１に近い部位あるいは中間繊維層４に「周囲よりも冷感剤坪量が少ない領域」を有する場合、「周囲よりも冷感剤坪量が少ない領域」の冷感剤の含有坪量は、他の領域の冷感剤の含有坪量の８５％以下であることが好ましく、７５％以下であることがより好ましく、６５％以下であることが更に好ましい。In the napkin 10, the cooling sensation agent is effectively delivered to the skin even if the remaining amount is reduced by the action of the dividing portion 8 described later, so that it is not necessary to increase the content excessively. Therefore, it is possible to suppress irritation to the skin while maintaining the same content as before, and to maintain an appropriate cooling effect effectively for a long time.
Specifically, the content of the cooling sensation agent in the entire napkin 10 is, for example, in the case of menthyl lactate, with respect to the product length from the viewpoint of the effect of reducing the feeling of cooling and stickiness. Is preferably 4 mg / 100 mm or more, more preferably 5 mg / 100 mm or more, and even more preferably 6.5 mg / 100 mm or more. From the viewpoint of suppressing irritation to the skin, the content is preferably 13.5 mg / 100 mm or less, more preferably 12.5 mg / 100 mm or less, and still more preferably 11.5 mg / 100 mm or less.
Further, when the region near the surface layer 1 or the intermediate fiber layer 4 in the absorption layer 3 at the center in the width direction of the intermediate part C has a “region having a lower basis weight of the cooling sensation than the surroundings”, the “cooling sensation than the surroundings” The basis weight of the cooling sensation agent in the region having a small basis weight is preferably 85% or less, more preferably 75% or less, and more preferably 65% or less of the cooling basis weight of the cooling sensation agent in other regions. More preferably.

（冷感剤の含有の有無、含有量の測定方法）
吸収性物品の対象部材又は対象部位から冷感剤を溶媒で抽出し、抽出溶液をガスクロマトグラフィ法（ＧＣ）で分析することができる。測定は、ガスクロマトグラフに取り付けた水素炎イオン化型検出器（ＦＩＤ）で行い、例えば、Agilent technologies製7890Aにより測定することができる。予め冷感剤を構成する化合物の濃度とピーク面積の関係を検量線化しておき、当該検量線を基に定量作業を行う。
冷感剤が乳酸メンチル及び／又はメントールを含む場合を例に説明する。溶媒としてメタノールを使用して対象部材又は対象部位から乳酸メンチル及び／又はメントールを抽出する。メタノールを溶媒として、予め濃度の異なる３〜５段階程度の乳酸メンチル溶液及び／又はメントール溶液を準備し、ＧＣのクロマトグラムからそれぞれの濃度のピーク面積を算出し、標準試料として、ｎ−ペンチルアルコールを用い、標準試料の濃度に対してそのピーク面積をプロットした検量線を作成する。検量線を作成した分析と同じ条件で抽出液の分析を行うことで、得られたピーク面積を検量線にあてはめて乳酸メンチル量及び／又はメントール量を算出する。また、得られた乳酸メンチル量及び／又はメントール量を、予め採取した製品部位の面積で除することにより、単位面積当たりの冷感剤量（冷感剤坪量）を求めることができる。また、得られた乳酸メンチル量及び／又はメントール量を、吸収性物品長さ方向の長さ（ｍｍ）で除し、１００倍することで、製品長さ１００ｍ当りの冷感剤量を求めることができる。
製品の各構成部材又は部位ごとの冷感剤量を知るには、５℃のチャンバー内で製品を分解し、測定する材料部位を取り出すことで分析可能となる。(Presence / absence of inclusion of cooling sensation agent, content measurement method)
The cooling sensation agent can be extracted with a solvent from the target member or target part of the absorbent article, and the extracted solution can be analyzed by gas chromatography (GC). The measurement can be performed with a flame ionization detector (FID) attached to a gas chromatograph, and can be measured with, for example, 7890A manufactured by Agilent Technologies. The relationship between the concentration of the compound constituting the cooling sensation agent and the peak area is prepared in advance as a calibration curve, and quantitative work is performed based on the calibration curve.
The case where the cooling sensation agent includes menthyl lactate and / or menthol will be described as an example. Methanol lactate and / or menthol is extracted from the target member or target site using methanol as a solvent. Prepare methanol and / or menthol solutions of about 3 to 5 stages with different concentrations using methanol as a solvent, calculate the peak area of each concentration from the GC chromatogram, and use n-pentyl alcohol as a standard sample. Is used to create a calibration curve in which the peak area is plotted against the concentration of the standard sample. By analyzing the extract under the same conditions as the analysis for creating the calibration curve, the obtained peak area is applied to the calibration curve to calculate the amount of menthol lactate and / or the amount of menthol. Moreover, the amount of the cooling sensate per unit area (cooling sensation basis weight) can be calculated | required by remove | dividing the amount of lactic acid menthyl and / or menthol obtained by the area of the product part extract | collected previously. Moreover, the amount of the cooling sensitizer per 100 m of product length is calculated | required by dividing the amount of lactic acid menthyl and / or menthol obtained by the length (mm) of an absorbent article length direction, and multiplying by 100. Can do.
In order to know the amount of the cooling sensation agent for each component or part of the product, it is possible to analyze by disassembling the product in a 5 ° C. chamber and taking out the material part to be measured.

吸収層３は分断部８を有する。
分断部８とは、吸収層３の構成材料の連続性が断絶された部分であり、部材のない隙間部分である。例えば、細長く切り込まれたスリット部であってもよく、部材の一部が押圧されて窪んだ凹部空間であってもよく、部材の坪量が部分的に小さくされた凹部空間であってもよい。The absorption layer 3 has a dividing portion 8.
The parting part 8 is a part where the continuity of the constituent material of the absorption layer 3 is interrupted, and is a gap part without a member. For example, it may be a slit portion that is cut into a long and narrow shape, may be a recessed space that is depressed by pressing a part of the member, or may be a recessed space in which the basis weight of the member is partially reduced. Good.

本実施形態においては、分断部８はスリット部８１として配されている（図１〜３参照）。スリット部８１は吸収層３の平面領域において複数分散して配列されている。ここで言う「スリット部」は、部材断絶の幅が０．５ｍｍ以下の切り込み部分として定義でき、好ましくは０．３ｍｍ以下であり、より好ましくは０．２ｍｍ以下である。スリット部８１の「幅」とは、ナプキン１０の平面視において、スリット部８１の延出する長さ方向に直交する方向の、断絶された部材間の距離（開口幅）をいう。スリット部８１の幅は、ナプキン１０から吸収層３を取り出して水平な台に静置し、張力を加えない自然状態において、株式会社キーエンス製のデジタルマイクロスコープＶＨＸ−１０００によって測定することができる。そのとき測定倍率は適宜調整して測定する。
スリット部８１については、吸収層３の好ましい具体的態様の説明とともに後述する。In this embodiment, the dividing part 8 is arranged as the slit part 81 (refer FIGS. 1-3). A plurality of slit portions 81 are arranged in a dispersed manner in the planar region of the absorption layer 3. The “slit portion” as used herein can be defined as a cut portion having a member breakage width of 0.5 mm or less, preferably 0.3 mm or less, and more preferably 0.2 mm or less. The “width” of the slit portion 81 refers to the distance (opening width) between the disconnected members in a direction orthogonal to the length direction in which the slit portion 81 extends in the plan view of the napkin 10. The width of the slit portion 81 can be measured by a digital microscope VHX-1000 manufactured by Keyence Corporation in a natural state in which the absorbent layer 3 is taken out from the napkin 10 and left on a horizontal base, and no tension is applied. At that time, the measurement magnification is appropriately adjusted and measured.
The slit portion 81 will be described later together with a description of a preferred specific mode of the absorption layer 3.

分断部８が、部分的に坪量の小さい凹部空間８２である場合の具体例としては、例えば、図４（Ａ）及び（Ｂ）に示す吸収層３１０Ａ及び３１０Ｂが挙げられる。これらは、親水性繊維の積繊体または親水性繊維と高吸収性ポリマー材との混合積繊体であって、所定の厚みを有し、部分的に坪量が減じられた凹凸形状を有する。ここでいう高吸収性ポリマー材はいわゆるＳＡＰと呼ばれる表面架橋された高分子材料である（以下、同様）。
具体的には、図４（Ａ）に示す吸収層３１０Ａは、表面層１側（肌面側）にブロック状の凸部３１１を複数有し、凸部３１１、３１１間に、坪量の小さい凹部空間８２を分断部８として複数有する。また、図４（Ｂ）に示す吸収層３１０Ｂは、裏面層２側（非肌面側）に、ブロック状の凸部３１１と、分断部８としての凹部空間８２とを複数有する。図４（Ａ）においては裏面層２側に、図４（Ｂ）においては表面層１側に、凹部空間８２の底を塞いで凸部３１１同士を繋ぐ薄皮部３１２を有する。As a specific example when the parting part 8 is the recessed part space 82 with a small basis weight partially, the absorption layers 310A and 310B shown to FIG. 4 (A) and (B) are mentioned, for example. These are laminated fibers of hydrophilic fibers or mixed fibers of hydrophilic fibers and a superabsorbent polymer material, and have a predetermined thickness and an uneven shape with a partially reduced basis weight. . The superabsorbent polymer material here is a so-called SAP-crosslinked polymer material (hereinafter the same).
Specifically, the absorption layer 310A illustrated in FIG. 4A includes a plurality of block-shaped convex portions 311 on the surface layer 1 side (skin surface side), and the basis weight is small between the convex portions 311 and 311. A plurality of recessed spaces 82 are provided as the divided portions 8. Moreover, the absorption layer 310B shown in FIG. 4B has a plurality of block-shaped convex portions 311 and a plurality of concave spaces 82 as the dividing portions 8 on the back layer 2 side (non-skin surface side). In FIG. 4A, a thin skin portion 312 is provided on the back surface layer 2 side and in FIG. 4B on the front surface layer 1 side to close the bottom of the concave space 82 and connect the convex portions 311 to each other.

更に分断部８は、表面層１及び吸収層３が裏面層２側に向かって一体的に凹陥してなる圧密化された凹部空間、すなわち線状溝でもよい。該線状溝は、平面視したときに、中間部Ｃにおいて縦方向（Ｙ方向）に延びる縦溝と、前方部Ｆ及び後方部Ｒにおいて、それぞれ幅方向（Ｘ方向）に延びるように形成された第１及び第２の横溝とを含む。線状溝は、熱を伴うか又は伴わない圧搾加工（いわゆるエンボス加工）、あるいは超音波エンボス等のエンボス加工により常法に従って形成することができる。線状溝においては、表面層１及び吸収層３との間が、図示しないが、接着剤を介して圧着されるか、あるいは熱融着等により一体化している。表面層１と吸収層３との間が結合しているという表現には、表面層１と吸収層３との間に中間繊維層４等の他の層が介在し、その表面層と当該他の層とが接合され、更に当該他の層と吸収層３とが接合（結合）している場合も含まれる。
このような線状溝は、吸収層３の平面方向の液の拡散を抑制して、ナプキン１０の周囲から液漏れを効果的に防止することができる。線状溝の幅（長さ方向と直交する方向の長さ）及び深さは、この種の吸収性物品における線状溝と同様に設定すればよい。また、線状溝における「線状」とは、溝（凹陥部）の形状が平面視において直線に限られず、曲線を含み、各線は、連続線でも破線でも良い。例えば、線状溝は、不連続な多数の点エンボスのなす列から構成されていてもよい。Further, the dividing portion 8 may be a consolidated recessed space, that is, a linear groove, in which the front surface layer 1 and the absorption layer 3 are integrally recessed toward the back surface layer 2 side. The linear grooves are formed so as to extend in the longitudinal direction (Y direction) at the intermediate portion C and to extend in the width direction (X direction) at the front portion F and the rear portion R when viewed in plan. First and second transverse grooves. A linear groove | channel can be formed in accordance with a conventional method by embossing, such as a pressing process (what is called embossing) with or without heat (what is called embossing), or ultrasonic embossing. In the linear groove, the surface layer 1 and the absorption layer 3 are not shown in the figure, but are bonded through an adhesive or integrated by heat fusion or the like. In the expression that the surface layer 1 and the absorbent layer 3 are bonded, another layer such as an intermediate fiber layer 4 is interposed between the surface layer 1 and the absorbent layer 3, and the surface layer and the other layer And the other layer and the absorbing layer 3 are joined (bonded).
Such a linear groove can prevent liquid leakage from the periphery of the napkin 10 by suppressing the diffusion of the liquid in the planar direction of the absorption layer 3. What is necessary is just to set the width | variety (length of the direction orthogonal to a length direction) and depth of a linear groove similarly to the linear groove in this kind of absorbent article. In addition, “linear” in the linear groove is not limited to a straight line in the plan view, but includes a curved line, and each line may be a continuous line or a broken line. For example, the linear groove may be composed of a row formed by a large number of discontinuous point embosses.

分断部８は、前述した冷感剤を含む領域と、ナプキン１０の平面視において重なる位置に配されている。平面視において重なる位置にある限り、分断部８が配される領域と冷感剤を含む領域とは、同じ厚み位置にあってもよく、異なる厚み位置にあってもよい。後述の分断部８の冷感剤に対する作用を考慮すると、分断部８が配される吸収層３の領域に冷感剤が含まれていることが好ましい。   The dividing portion 8 is disposed at a position overlapping the above-described region containing the cooling sensate in the plan view of the napkin 10. As long as it exists in the position which overlaps in planar view, the area | region where the parting part 8 is distribute | arranged, and the area | region containing a cooling agent may be in the same thickness position, and may be in a different thickness position. Considering the action of the dividing portion 8 described later on the cooling sensation agent, it is preferable that the cooling sensation agent is contained in the region of the absorption layer 3 where the dividing portion 8 is disposed.

分断部８は、吸収層３の厚み方向においてどの位置にあってもよく、表面層１側（肌面側）にあってもよく、表面層１側から所定深さにまであってもよく、吸収層３の厚み方向全体に亘ってあってもよい。後述の分断部８の冷感剤に対する作用を考慮すると、分断部８は少なくとも吸収層３の表面層１側（肌面側）に配されることが好ましい。   The dividing portion 8 may be located at any position in the thickness direction of the absorbent layer 3, may be on the surface layer 1 side (skin surface side), or may be a predetermined depth from the surface layer 1 side, You may exist over the whole thickness direction of the absorption layer 3. FIG. Considering the action of the divided portion 8 described later on the cooling sensation agent, the divided portion 8 is preferably arranged at least on the surface layer 1 side (skin surface side) of the absorbent layer 3.

分断部８は、吸収層３の構成部材の非連続部分であることから、吸収層３の変形の軸となり得る。例えば、ナプキン１０装着時に、着用者の身体の動きに合わせてナプキン１０の幅方向内方への押圧や前後方向のせん断力等の外力が加わったときに、分断部８を基軸として、吸収層３が変形することができる。これにより分断部８が、吸収層３の変形の仕方によって、一方で空気を溜める空間（例えば図５（Ａ）及び（Ｂ）の符号Ｐで示す領域）を形成し、他方で空気を移動（例えば図５（Ａ）に示す矢印Ｆ）させる通気路を形成することができる。分断部８が通気路となる際には、吸収層３の変形の力が空気を押し出す駆動力として作用する。   Since the dividing portion 8 is a discontinuous portion of the constituent members of the absorbing layer 3, it can be a deformation axis of the absorbing layer 3. For example, when the napkin 10 is mounted, when an external force such as a pressure inward in the width direction of the napkin 10 or a shearing force in the front-rear direction is applied in accordance with the movement of the wearer's body, 3 can be deformed. As a result, the dividing portion 8 forms a space for storing air (for example, a region indicated by reference sign P in FIGS. 5A and 5B) on the one hand and moves air on the other (depending on how the absorption layer 3 is deformed). For example, it is possible to form a ventilation path that is made to be an arrow F shown in FIG. When the dividing portion 8 becomes a ventilation path, the deformation force of the absorption layer 3 acts as a driving force for pushing out air.

このとき、分断部８が冷感剤を含む領域と平面視において重なる位置にあることによって、分断部８の作用による空気の移動（例えば図５（Ａ）に示す矢印Ｆ）に連動して、冷感剤の揮発した成分も移動し易くなる。
すなわち吸収層３の動きの中で空気が出入りすると、吸収層３内部又は部材間に溜まる冷感剤の揮発成分が着用者の肌面へと押し上げられ、効果的に冷感作用が発現する。特に時間が経って冷感剤の含有残存量が少なくなってきたときに、肌面へと、冷感剤の揮発成分を十分に送り込むことができる。例えば、冷感剤が吸収層３の奥に滲出して残存する場合には、吸収層３内部から肌面へと冷感剤の揮発成分を積極的に送り込むことができる。これにより、ナプキン１０は冷感効果をより長く効果的に維持させることができる。なお、吸収層３の両面において、防漏性の裏面層２よりも液透過性の表面層１の方が空気の出入りが大きくなることは、上記の肌面への押し上げを更に効果的にする。At this time, since the dividing portion 8 is in a position overlapping with the region containing the cooling sensate in plan view, in conjunction with the movement of air by the action of the dividing portion 8 (for example, arrow F shown in FIG. 5A), The volatilized components of the cooling sensation agent are also easily moved.
That is, when air enters and exits during the movement of the absorption layer 3, the volatile component of the cooling sensation agent that accumulates in the absorption layer 3 or between the members is pushed up to the skin surface of the wearer, and a cooling effect is effectively exhibited. In particular, when the remaining amount of the cooling sensation agent decreases with time, the volatile component of the cooling sensation agent can be sufficiently fed to the skin surface. For example, when the cooling sensation agent exudes and remains in the back of the absorption layer 3, the volatile component of the cooling sensation agent can be actively sent from the inside of the absorption layer 3 to the skin surface. Thereby, the napkin 10 can maintain the cooling effect more effectively effectively. In addition, on both surfaces of the absorption layer 3, the fact that the liquid permeable surface layer 1 has greater air inflow and outflow than the leakproof back surface layer 2 makes the above-mentioned push up to the skin surface more effective. .

なお、図５（Ａ）及び（Ｂ）は分断部８を軸とした吸収層３の変形を模式的に示しており、実際の変形はこれに限定されるものではない。また、図５（Ａ）に示す矢印Ｆの空気の移動と図５（Ｂ）の符号Ｐで示す空気が溜まる領域の形成とが時間的に異なる場面にて生じるとは限らず、分断部８が配される領域内の異なる場所で同時に生じることもあり得る。さらに、符号Ｐで示す空気が溜まる領域は、分断部８付近のみで生じるものではなく、後述のとおり層間の空間にも生じ得る。層間の空間における空気溜まりは分断部８を軸とした変形の有無に拘らず生じ、該空気及び冷感剤の揮発成分が分断部８を軸とした変形によって肌面へと押し出されることとなる。   5A and 5B schematically show the deformation of the absorbing layer 3 with the dividing portion 8 as an axis, and the actual deformation is not limited to this. In addition, the movement of the air indicated by the arrow F shown in FIG. 5A and the formation of the air accumulation area indicated by the reference symbol P shown in FIG. May occur simultaneously at different locations within the region where the Furthermore, the area where the air indicated by the symbol P is accumulated is not generated only in the vicinity of the dividing portion 8, but can also be generated in a space between layers as described later. Air accumulation in the space between layers occurs regardless of the presence or absence of deformation with the dividing portion 8 as an axis, and the volatile components of the air and the cooling sensation agent are pushed out to the skin surface by the deformation with the dividing portion 8 as an axis. .

分断部８は、肌への好適な冷感付与の観点から、吸収層３の幅方向両端縁３９よりも内側の領域に配されることが好ましい。ここで言う「吸収層３の幅方向両端縁３９よりも内側の領域」とは、着用者の肌の鼠蹊部の付近を避けた領域を言う。具体的には、幅方向の両端縁３９を含まずに幅方向の中心線Ｌから左右に対称に広がる領域であって、吸収層幅に対して８５％以下の範囲の領域であることが好ましく、吸収層幅に対して７０％以下の範囲の領域であることがより好ましい。また、吸収層３の幅方向において最も外側に配置される分断部８は、冷感剤の滲出を制御する観点から、冷感剤が含まれる領域よりも幅方向外側に配されることがより好ましい。上記配置の分断部８による優先的な冷感付与によって、着用者の鼠蹊部などの肌の敏感な部分への刺激を抑制し、着用者に好適な冷感を感じさせることができる。なお、ここでの吸収層３の幅は、吸収層３の中間部Ｃにおける最小幅を意味する。したがって、吸収層３が矩形の場合には、吸収層３の幅は、中間部Ｃにおいて吸収層３の幅方向におけるいかなる部分における幅方向長さであってもよい。一方で、前後部で幅が広く、中間部Ｃで幅が狭い、例えば砂時計形状のような場合には、中間部Ｃにおける最も幅の狭い部分の幅方向長さが吸収層３の幅となる。
また、分断部８は、肌への好適な冷感付与の観点か、吸収層３の縦方向において少なくとも中間部Ｃを含む領域に配されることが好ましい。It is preferable that the parting part 8 is distribute | arranged to the area | region inside the width direction both ends edge 39 of the absorption layer 3 from a viewpoint of suitable cooling sensation provision to skin. Here, the “region inside the widthwise end edges 39 of the absorbent layer 3” refers to a region that avoids the vicinity of the buttocks of the wearer's skin. Specifically, it is a region that does not include both end edges 39 in the width direction and extends symmetrically from the center line L in the width direction, and is preferably a region in a range of 85% or less with respect to the absorption layer width. It is more preferable that the region be in the range of 70% or less with respect to the absorption layer width. Moreover, the parting part 8 arrange | positioned on the outermost side in the width direction of the absorption layer 3 may be more arranged in the width direction outer side than the area | region where a cooling sensation agent is contained from a viewpoint of controlling the exudation of a cooling sensation agent. preferable. By preferentially imparting a cool sensation by the dividing portion 8 having the above arrangement, it is possible to suppress irritation to sensitive parts of the skin such as the buttocks of the wearer and to make the wearer feel a suitable cool sensation. Here, the width of the absorption layer 3 means the minimum width in the intermediate portion C of the absorption layer 3. Therefore, when the absorption layer 3 is rectangular, the width of the absorption layer 3 may be the length in the width direction at any portion in the width direction of the absorption layer 3 in the intermediate portion C. On the other hand, the width in the width direction of the narrowest part in the intermediate part C becomes the width of the absorption layer 3 in the case where the width is wide at the front and rear parts and narrow at the intermediate part C, such as an hourglass shape. .
Moreover, it is preferable that the parting part 8 is distribute | arranged to the area | region containing at least the intermediate part C in the vertical direction of the absorption layer 3 from the viewpoint of the suitable cooling feeling provision to skin.

肌の敏感な部分への刺激を抑制する観点から、前述したサイドシート５が、吸収層３の幅方向外方から吸収層３の幅方向両端縁３９を跨ぎ、縦方向に延出していることが好ましい。また、少なくとも中間部Ｃにおいて、サイドシート５の幅方向内側端が、最も幅方向外側に位置する分断部８より幅方向外側にあることが好ましい。これにより、仮に冷感剤が分断部８を越えて滲出する場合でも、サイドシート５が、冷感剤の揮発成分が着用者の鼠蹊部の付近を直接的に刺激することを抑えることができる。このとき、サイドシート５が表面層１よりも通気性が低いことが、肌刺激のより効果的な抑制の観点から好ましい。通気性は、この種の物品に用いられる方法により適宜設定できる。例えば、サイドシート５が不織布からなる場合に、繊維間距離を狭めたり、用いる油剤を選択したりして通気性を抑えることができる。通気性は、ＪＩＳ Ｌ１９１３の「６．８．２ ガーレ形式」によって測定したときに、サイドシート５の通気度が表面層１の通気度よりも低いことが好ましい。なお、サイドシートが当該ガーレ形式で測定できないほど小さい場合には、サイドシートを、その大きさより小さい開口を有する非通気性のフィルム材（好ましくは、コクヨ製ＯＨＰフィルム等）に貼り付けて測定を行い、開口面積値を当該ガーレ形式で規定される面積（６４２ｍｍ２）に換算する。From the viewpoint of suppressing irritation to sensitive skin, the side sheet 5 described above extends from the outer side of the absorbent layer 3 in the width direction across the both edges 39 in the width direction of the absorbent layer 3 and extends in the vertical direction. Is preferred. Moreover, it is preferable that the width direction inner side edge of the side seat | sheet 5 exists in the width direction outer side rather than the parting part 8 located in the width direction outermost side at least in the intermediate part C. Thereby, even when a cooling agent exudes over the parting part 8, it can suppress that the volatile component of a cooling agent stimulates the vicinity of a wearer's buttocks directly. . At this time, it is preferable from the viewpoint of more effective suppression of skin irritation that the side sheet 5 has lower air permeability than the surface layer 1. The air permeability can be appropriately set by a method used for this type of article. For example, when the side sheet 5 is made of a nonwoven fabric, the air permeability can be suppressed by narrowing the distance between fibers or selecting an oil agent to be used. The air permeability is preferably such that the air permeability of the side sheet 5 is lower than the air permeability of the surface layer 1 when measured according to “6.8.2 Gurley type” of JIS L1913. When the side sheet is too small to be measured in the Gurley format, the side sheet is attached to a non-breathable film material (preferably an OH film made by KOKUYO, etc.) having an opening smaller than the size. The opening area value is converted into an area (642 mm 2 ) defined in the Gurley format.

また、前述した中間繊維層４が、表面層１と吸収層３との間において、平面視で冷感剤を含む領域と重なる部位にあることが好ましい。これにより、表面層１の非肌面側において、冷感剤の揮発した成分を溜める層間の空間が増える。また、中間繊維層４の介在により、冷感剤を長持ちさせ、丁度よい冷感を付与することができる。この場合、冷感剤は、中間繊維層４に含まれていてもよく、含まれていなくてもよい。冷感剤による冷感効果を長く効果的に維持する観点から、冷感剤の含有量が最も多い領域が吸収層３（特に吸収層３の肌面側）にあることが好ましい。   Moreover, it is preferable that the intermediate fiber layer 4 described above is located between the surface layer 1 and the absorption layer 3 in a portion overlapping a region containing the cooling sensate in plan view. Thereby, in the non-skin surface side of the surface layer 1, the space between the layers which accumulate | stores the component which the cooling agent volatilized increases. In addition, the intermediary fiber layer 4 allows the cooling sensation agent to last for a long time and imparts just the right cooling sensation. In this case, the cooling sensation agent may or may not be contained in the intermediate fiber layer 4. From the viewpoint of effectively maintaining the cooling sensation effect by the cooling sensation for a long time, it is preferable that the region having the largest content of the cooling sensation agent is in the absorption layer 3 (particularly the skin side of the absorption layer 3).

中間繊維層４は、表面層１と幅方向に間欠配置された縦方向に延びる複数の接着剤で接合されていることが好ましい。同様に、中間繊維層４は、吸収層３と幅方向に間欠配置された縦方向に延びる複数の接着剤で接合されていることが好ましい。接着剤の幅方向における間欠配置は、この種の物品について用いられる種々の方法により行うことができる。例えば、ホットメルト型等の接着剤を、線状、スパイラル状、Ω字状、サミット状等に間欠塗工することが挙げられる。このとき、スロットコートガン、スパイラルスプレーガン、スプレーガン、ドットガンなど種々の手段を用いて塗工することができる。
これにより、前記接着剤が、冷感剤が幅方向外方へと拡散することを抑制することができ、所望の場所での冷感効果を維持することができる。
また、吸収層３の肌面側表面積に占める、前記接着剤が配されている面積の割合は、吸液性（液透過性）の確保の観点から、好ましく２０％以下であり、より好ましくは１５％以下であり、更に好ましくは１０％以下である。また、前記接着剤の中間部Ｃにおける吸収層幅に対する塗工幅の割合は、前述の冷感剤の幅方向外方への拡散を抑制する観点から、好ましくは４５％以上であり、より好ましくは６０％以上であり、更に好ましくは７５％以上である。なお、ここで言う「接着剤の塗工幅」は、接着剤が幅方向に間欠的に配されている場合は、各塗工部分における接着剤の幅の合計である。The intermediate fiber layer 4 is preferably bonded to the surface layer 1 with a plurality of adhesives that are intermittently arranged in the width direction and extend in the longitudinal direction. Similarly, it is preferable that the intermediate fiber layer 4 is joined to the absorbent layer 3 with a plurality of adhesives extending in the longitudinal direction that are intermittently arranged in the width direction. The intermittent arrangement of the adhesive in the width direction can be performed by various methods used for this type of article. For example, an adhesive such as a hot melt type may be intermittently applied in a linear shape, spiral shape, Ω-shape, summit shape, or the like. At this time, coating can be performed using various means such as a slot coat gun, a spiral spray gun, a spray gun, and a dot gun.
Thereby, the said adhesive agent can suppress that a cooling sensation agent spread | diffuses in the width direction outward, and can maintain the cooling sensation effect in a desired place.
Moreover, the ratio of the area where the said adhesive agent is occupying in the skin surface side surface area of the absorption layer 3 is 20% or less from a viewpoint of ensuring liquid absorptivity (liquid permeability), More preferably It is 15% or less, more preferably 10% or less. Moreover, the ratio of the coating width with respect to the absorption layer width in the intermediate portion C of the adhesive is preferably 45% or more, more preferably from the viewpoint of suppressing the diffusion of the cooling sensation agent outward in the width direction. Is 60% or more, more preferably 75% or more. The “adhesive coating width” referred to here is the total of the widths of the adhesive in each coating portion when the adhesive is intermittently arranged in the width direction.

さらに中間繊維層４は熱可塑性繊維を含む不織布であることが好ましい。中間繊維層４がこのような不織布であることによって液拡散性の高いものとなる。これによって、冷感剤が中間繊維層４に含まれる場合、吸収層３の肌面側に含まれる場合のいずれであっても、冷感剤が非肌面側へと厚み方向に滲出することを抑制して、冷感効果がより長く維持されやすくなる。
また、中間繊維層４は、表面層１よりも繊維密度が高いことが好ましい。この疎密勾配効果によって、表面層１への冷感剤の移行量を中間繊維層４の面で制御しつつ、分断部８の作用によって分断部８から優先的に冷感剤の揮発成分を肌へと送り込むことができる。この結果、肌への過度な刺激を抑えながら長時間冷感を保つことができる。Furthermore, the intermediate fiber layer 4 is preferably a nonwoven fabric containing thermoplastic fibers. When the intermediate fiber layer 4 is such a nonwoven fabric, the liquid diffusibility is high. As a result, when the cooling sensation agent is included in the intermediate fiber layer 4 or when it is included in the skin surface side of the absorption layer 3, the cooling sensation agent exudes in the thickness direction toward the non-skin surface side. Is suppressed, and the cooling effect is easily maintained for a longer time.
The intermediate fiber layer 4 preferably has a higher fiber density than the surface layer 1. Due to the density gradient effect, the amount of the cooling sensate transferred to the surface layer 1 is controlled by the surface of the intermediate fiber layer 4, and the volatile components of the cooling sensation are preferentially removed from the dividing part 8 by the action of the dividing part 8. Can be sent to. As a result, it is possible to maintain a cool feeling for a long time while suppressing excessive irritation to the skin.

吸収層３としては、分断部８による上記作用を奏する限り、吸収性物品として通常用いられる種々の形態のものを特に制限なく採用することができる。例えば、親水性繊維の積繊体または親水性繊維と高吸収性ポリマー材との混合積繊体を親水性の被覆シートで覆ったものでもよい。また、親水性繊維からなる２つのシート状の繊維層間に高吸収性ポリマー材を挟持して固定した薄い吸収性シートから構成されていてもよい。吸収性シートの形成にあたっては、高吸収性ポリマーが湿潤によって発現する粘着力や別に添加した接着剤や接着性繊維等のバインダーを利用して一体化することができる。作製は通常用いられる種々の方法によって行うことができ、湿式、乾式いずれの方式によってもよい。
吸収性シートは厚みを３．０ｍｍ以下に抑えながら、高吸収性ポリマー材をシートの平面方向に分散配置させているためゲルブロッキングを起こし難く、高い吸収力を有する。例えば、特開平８−２４６３９５号公報の段落［００１９］〜［０１３１］に記載のものなどが挙げられる。As the absorbent layer 3, various forms that are usually used as absorbent articles can be used without particular limitation as long as the above-described action of the dividing portion 8 is achieved. For example, a laminated fiber of hydrophilic fibers or a mixed fiber of hydrophilic fibers and superabsorbent polymer material may be covered with a hydrophilic covering sheet. Moreover, you may be comprised from the thin absorbent sheet which pinched | interposed and fixed the superabsorbent polymer material between the two sheet-like fiber layers which consist of a hydrophilic fiber. In the formation of the absorbent sheet, the superabsorbent polymer can be integrated by using an adhesive force developed by wetting and a binder such as a separately added adhesive or adhesive fiber. Manufacture can be performed by various commonly used methods, and may be either wet or dry.
The absorbent sheet has a high absorbency because it is difficult to cause gel blocking because the superabsorbent polymer material is dispersed and arranged in the plane direction of the sheet while suppressing the thickness to 3.0 mm or less. Examples thereof include those described in paragraphs [0019] to [0131] of JP-A-8-246395.

吸収層３は、前述した高吸収性ポリマー材及び親水性繊維を含む吸収性シートから構成されていることが好ましい。これにより、吸収層３の薄型化が可能であり、分断部８が所望の位置に配置しやすく、冷感付与を所望の位置で強化することができる。   The absorbent layer 3 is preferably composed of an absorbent sheet containing the above-described superabsorbent polymer material and hydrophilic fibers. Thereby, thickness reduction of the absorption layer 3 is possible, the parting part 8 is easy to arrange | position in a desired position, and cooling provision can be strengthened in a desired position.

吸収層３としては、分断部８によって冷感剤の揮発成分を肌面へとより効果的に送り込む観点から、厚み方向に積層構造を有することが好ましい。吸収層３が積層構造を有すると、吸収層３の変形の有無にかかわらず、層間の空間に冷感剤の揮発した成分を溜めやすくなる。また、冷感剤が吸収層３内に滲出する場合、同一層内での移動が生じやすく、厚み方向への冷感剤の滲出量を抑制することができる。これにより吸収層３内の肌面側に近い層間において冷感剤の揮発した成分を溜めることができる。このようにして層間に十分に溜まった冷感剤の揮発した成分は、吸収層３の変形によって層間が開閉して、分断部８によってできる通気路を通じて肌面へと送り込まれ、適度な冷感を長く感じさせることができる。   The absorbent layer 3 preferably has a laminated structure in the thickness direction from the viewpoint of more effectively sending the volatile components of the cooling sensate to the skin surface by the dividing portion 8. When the absorption layer 3 has a laminated structure, it is easy to store the volatilized component of the cooling sensation agent in the space between the layers regardless of whether or not the absorption layer 3 is deformed. Moreover, when a cooling sensation agent oozes out in the absorption layer 3, the movement within the same layer is easy to occur, and the oozing amount of the cooling sensation agent in the thickness direction can be suppressed. Thereby, the component which the cooling sensation volatilized in the layer close | similar to the skin surface side in the absorption layer 3 can be collected. In this way, the volatilized component of the cooling agent sufficiently accumulated between the layers opens and closes due to the deformation of the absorption layer 3 and is sent to the skin surface through the air passage formed by the dividing portion 8, so that an appropriate cooling sensation is provided. Can make you feel longer.

吸収層３は、上記の層間の開閉性を高める観点から、前述した吸収性シートを積層させた構造であることがより好ましい。またこれにより、吸収層３の所望の場所に分断部８を設けやすくなり、着用者に付与する冷感をより精度よく制御することが可能となる。   The absorbent layer 3 is more preferably a structure in which the above-described absorbent sheets are laminated from the viewpoint of improving the openability of the interlayer. Moreover, it becomes easy to provide the parting part 8 in the desired location of the absorption layer 3, and it becomes possible to control the cool feeling given to a wearer more precisely.

次に、吸収層３の好ましい具体的な構造と、吸収層３における分断部８の好ましい配置について説明する。   Next, a preferable specific structure of the absorption layer 3 and a preferable arrangement of the dividing portions 8 in the absorption layer 3 will be described.

図２及び３に示す吸収層３は、前述した高吸収性ポリマー及び親水性繊維を含む吸収性シートから構成されている。吸収性シートが積層された構造を有する。より具体的には、吸収層３は、本体吸収性シート３１と、本体吸収性シート３１の非肌面側に配された中央吸収性シート３２とを有し、両吸収性シートが折り畳まれた積層構造を有する。これにより、冷感剤が折り畳まれたシート層の面方向に拡散しやすく、冷感剤が吸収層３の非肌面側へと厚み方向に滲出することをより効果的に抑制することができる。   The absorbent layer 3 shown in FIGS. 2 and 3 is composed of an absorbent sheet containing the above-described superabsorbent polymer and hydrophilic fibers. It has a structure in which absorbent sheets are laminated. More specifically, the absorbent layer 3 has a main body absorbent sheet 31 and a central absorbent sheet 32 disposed on the non-skin surface side of the main body absorbent sheet 31, and both absorbent sheets are folded. It has a laminated structure. Thereby, it is easy to diffuse in the surface direction of the sheet | seat layer by which the cooling sensation was folded, and it can suppress more effectively that a cooling sensation agent exudes to the non-skin surface side of the absorption layer 3 in the thickness direction. .

本体吸収性シート３１は、裏面層２側で幅方向の両端部を重ね合わせて三つ折りされた、折り畳み構造を有する。本体吸収性シート３１は、中間部Ｃから前方部Ｆ及び後方部Ｒに及ぶ長さを有し、吸収層３の外形形状をなしている。
中央吸収性シート３２は、表面層１側で幅方向の両端部を重ね合わせて三つ折りされた、折り畳み構造を有する。中央吸収性シート３２は、折り畳まれた状態において、折り畳まれた本体吸収性シート３１よりも幅狭であり、本体吸収性シート３１よりも縦方向の長さが短く、中間部Ｃの幅方向中央に配されている。中央吸収性シート３２は、本体吸収性シート３１の折り畳み構造の内部に収められている。この配置において、中央吸収性シート３２は、本体吸収性シート３１の肌面側ではなく非肌面側にあり、少なくとも本体吸収性シート３１の肌面側部分３１Ａよりも非肌面側に配されている。The main body absorbent sheet 31 has a folded structure that is folded in three on the back layer 2 side by overlapping both end portions in the width direction. The main body absorbent sheet 31 has a length extending from the intermediate part C to the front part F and the rear part R, and forms the outer shape of the absorbent layer 3.
The central absorbent sheet 32 has a folded structure that is folded in three on the surface layer 1 side by overlapping both end portions in the width direction. In the folded state, the central absorbent sheet 32 is narrower than the folded main body absorbent sheet 31, has a shorter length in the vertical direction than the main body absorbent sheet 31, and is centered in the width direction of the intermediate portion C. It is arranged in. The central absorbent sheet 32 is housed in the folding structure of the main body absorbent sheet 31. In this arrangement, the central absorbent sheet 32 is not on the skin surface side of the main body absorbent sheet 31 but on the non-skin surface side, and is disposed at least on the non-skin surface side of the skin surface side portion 31 </ b> A of the main body absorbent sheet 31. ing.

吸収層３は、上記の積層構造において、中央吸収性シート３２を有することによって、中間部Ｃの幅方向中央に、本体吸収性シート３１と中央吸収性シート３２との重なり部分として、周囲より厚い高坪量部３３を備える。高坪量部３３の位置において、ナプキン１０が着用者の肌面にフィットしやすく、冷感を着用者が感じやすくなり好ましい。また、吸収層３は、高坪量部３３におけるシートの積層構造によって、層間における厚み方向への冷感剤の滲出量を抑制することができる。これにより、冷感剤の揮発した成分を、中間部Ｃの領域において、吸収層３の比較的肌に近い位置で溜めて肌へと送り込むことができ好ましい。   In the laminated structure, the absorbent layer 3 has the central absorbent sheet 32, so that the absorbent layer 3 is thicker than the periphery as an overlapping portion of the main absorbent sheet 31 and the central absorbent sheet 32 at the center in the width direction of the intermediate portion C. A high basis weight portion 33 is provided. In the position of the high basic weight part 33, the napkin 10 is easy to fit a wearer's skin surface, and a wearer tends to feel a cool feeling, and it is preferable. Moreover, the absorption layer 3 can suppress the oozing amount of the cooling sensation agent in the thickness direction between the layers by the laminated structure of the sheets in the high basis weight portion 33. Thereby, the volatilized component of the cooling sensation agent can be accumulated in the region of the intermediate portion C at a position relatively close to the skin of the absorbent layer 3 and sent to the skin.

吸収層３において、高坪量部３３の厚み（Ｈ１）に対する、高坪量部３３以外の部分の厚み（Ｈ２）の比（Ｈ２／Ｈ１）は、肌面に対して違和感なく使用する観点から、１／５以上が好ましく、１／３以上がより好ましい。前記比（Ｈ２／Ｈ１）は、フィット性の観点から、４／５以下が好ましく、２／３以下がより好ましい。
また吸収層３において、高坪量部３３の坪量（Ｍ１）に対する、高坪量部３３以外の部分の坪量（Ｍ２）の比（Ｍ２／Ｍ１）は、***液吸収時の液拡散防止の観点から、１／４以上が好ましく、１／３以上がより好ましい。前記比（Ｍ２／Ｍ１）は、高坪量部と低坪量部の剛性差によるヨレ防止の観点から、７／８以下が好ましく、２／３以下がより好ましい。In the absorbent layer 3, the ratio (H2 / H1) of the thickness (H2) of the portion other than the high basis weight portion 33 to the thickness (H1) of the high basis weight portion 33 is used from the viewpoint of using the skin surface without a sense of incongruity. 1/5 or more is preferable, and 1/3 or more is more preferable. The ratio (H2 / H1) is preferably 4/5 or less and more preferably 2/3 or less from the viewpoint of fit.
In the absorption layer 3, the ratio (M2 / M1) of the basis weight (M2) of the portion other than the high basis weight portion 33 to the basis weight (M1) of the high basis weight portion 33 is the liquid diffusion prevention at the time of excretion fluid absorption. In view of the above, 1/4 or more is preferable, and 1/3 or more is more preferable. The ratio (M2 / M1) is preferably 7/8 or less, and more preferably 2/3 or less, from the viewpoint of preventing twist due to a difference in rigidity between the high basis weight part and the low basis weight part.

中央吸収性シート３２の折り畳み構造としては、図２に示す態様に限らず、種々のものとすることができる。例えば、図６（Ａ）〜（Ｄ）に示すような折り畳みであってもよい。図６（Ａ）は、中央吸収性シート３２の幅方向の両端部をそれぞれ肌面側と非肌面側とに折り返しＳ字状に折り畳んだ態様を示している。図６（Ｂ）は幅方向に二つ折りした態様を示している。図６（Ｃ）及び（Ｄ）は、幅方向に三つ折りした各部分の長さが等しくなるように折り畳んだ態様を示している。   The folding structure of the central absorbent sheet 32 is not limited to the mode shown in FIG. 2 and can be various. For example, it may be folded as shown in FIGS. FIG. 6A shows a state in which both end portions in the width direction of the central absorbent sheet 32 are folded back to the skin surface side and the non-skin surface side, respectively, and are folded in an S shape. FIG. 6B shows a state in which the sheet is folded in the width direction. 6 (C) and 6 (D) show a state in which each part folded in the width direction is folded to have the same length.

本体吸収性シート３１の折り畳み構造は、図２に示す態様に限らず、種々のものとすることができる。例えば、中央吸収性シート３２の折り畳み構造として示した図６（Ａ）〜（Ｄ）と同様のものとしてもよい。また肌面側と非肌面側とに分かれた２枚のシートを積層した構造であってもよい。さらに、本体吸収性シート３１の折り畳み構造の内部に中央吸収性シート３２を内包する態様に限定されず、内包せずに、本体吸収性シート３１の折り畳み構造の非肌面側に中央吸収性シート３２を積層する態様であってもよい。
ただし、本体吸収性シート３１の折り畳み構造の内部に中央吸収性シート３２を内包する態様であると、冷感剤の揮発成分をより溜めやすくなり、前述した分断部８の作用の観点から好ましい。The folding structure of the main body absorbent sheet 31 is not limited to the mode shown in FIG. 2 and can be various. For example, it is good also as a thing similar to FIG. 6 (A)-(D) shown as a folding structure of the center absorbent sheet 32. FIG. Moreover, the structure which laminated | stacked two sheets divided into the skin surface side and the non-skin surface side may be sufficient. Furthermore, the central absorbent sheet 32 is not limited to a mode in which the central absorbent sheet 32 is included in the folded structure of the main body absorbent sheet 31, and the central absorbent sheet is not disposed on the non-skin surface side of the folded structure of the main body absorbent sheet 31. 32 may be laminated.
However, a mode in which the central absorbent sheet 32 is included in the folded structure of the main body absorbent sheet 31 makes it easier to collect the volatile components of the cooling sensation agent, which is preferable from the viewpoint of the action of the dividing portion 8 described above.

吸収層３がどのような積層構造を有していても、吸収性シートの重なり部分が接合されないことが好ましい。これにより、吸収層３の層間の空間が形成されやすく、前述の層間の開閉性が高まる。その結果、分断部８を通じた冷感剤の揮発成分の肌への送り込みをより発現させやすくすることができる。   Whatever laminated structure the absorbent layer 3 has, it is preferable that the overlapping portion of the absorbent sheet is not joined. Thereby, the space between the layers of the absorption layer 3 is easily formed, and the opening / closing property between the above-described layers is enhanced. As a result, the feeding of the volatile component of the cooling sensation agent to the skin through the dividing portion 8 can be more easily expressed.

このような吸収層３において、分断部８はスリット部８１として複数配されている。
スリット部８１は、吸収層３を厚み方向に貫通して形成されている。高坪量部３３においては、スリット部８１は、本体吸収性シート３１と中央吸収性シート３２とを合わせた積層部分を貫通している。高坪量部３３以外の部分では、スリット部８１は、本体吸収性シート３１の積層部分全体を貫通している。これにより、高坪量部３３、高坪量部３３の以外の部分のいずれにおいても、吸収層３のスリット部８１の軸にした変形、層間の開閉がより確実に生じ得るので好ましい。In such an absorption layer 3, a plurality of dividing portions 8 are arranged as slit portions 81.
The slit portion 81 is formed so as to penetrate the absorption layer 3 in the thickness direction. In the high basis weight part 33, the slit part 81 has penetrated the laminated part which match | combined the main body absorbent sheet 31 and the central absorbent sheet 32. As shown in FIG. In portions other than the high basis weight portion 33, the slit portion 81 penetrates the entire laminated portion of the main body absorbent sheet 31. Thereby, in any part other than the high basis weight part 33 and the high basis weight part 33, the deformation of the axis of the slit part 81 of the absorbent layer 3 and the opening and closing of the layers can occur more reliably.

スリット部８１は、吸収層３を平面視した縦方向において、少なくとも中間部Ｃを含む領域に配されることが好ましい。また、スリット部８１のうち最も幅方向外側に位置するものは、前述のとおり、吸収層３の幅方向両端縁３９よりも内側にあり、冷感剤が含まれる領域よりも幅方向外側に配されることが好ましい。   The slit portion 81 is preferably arranged in a region including at least the intermediate portion C in the longitudinal direction of the absorption layer 3 in plan view. Further, as described above, the slit portion 81 that is located on the outermost side in the width direction is located on the inner side of the both end edges 39 in the width direction of the absorbent layer 3 and is arranged on the outer side in the width direction with respect to the region containing the cooling sensation agent. It is preferred that

スリット部８１は、吸収層３の平面視において縦方向に延びる長さを有して該縦方向に複数配列されている。該縦方向の配列が、幅方向に複数配されている。各列におけるスリット部８１の配置ピッチは、幅方向に隣接するスリット部８１の列同士において、縦方向にずれた配置とされている。以下、スリット部８１が縦方向に並ぶ各列をスリット部列という（各スリット部列を区別する場合は、８５Ａ、８５Ｂ、８５Ｃ・・・と称する。）。また、スリット部列が配される平面方向の領域をスリット部領域８６という。   The slit portion 81 has a length extending in the vertical direction in a plan view of the absorption layer 3 and is arranged in a plurality in the vertical direction. A plurality of the vertical arrays are arranged in the width direction. The arrangement pitch of the slit portions 81 in each row is shifted in the vertical direction between the rows of the slit portions 81 adjacent in the width direction. Hereinafter, each row in which the slit portions 81 are arranged in the vertical direction is referred to as a slit portion row (referred to as 85A, 85B, 85C... When distinguishing each slit portion row). A region in the planar direction where the slit portion row is arranged is referred to as a slit portion region 86.

スリット部８１、８１間の縦方向の間隔Ｌ２は、スリット部８１の長さ（縦方向の長さ）Ｌ１以下にすることが好ましい（図７（Ａ）〜（Ｃ）参照）。スリット部８１間の縦方向の間隔Ｌ２をできるだけ小さくすることによって、冷感剤が吸収層３の幅方向外方へと滲出することに対する抑制効果がより高くなる。この冷感剤の滲出抑制の観点から、スリット部８１、８１間の間隔Ｌ２は、スリット部領域８６全体として、吸収層３の断絶が無い連続部分の長さを意味する。スリット部領域８６が複数のスリット部列８５を有する場合は、全体を１つの列とみなして間隔Ｌ２を把握する。   The vertical interval L2 between the slit portions 81, 81 is preferably set to be equal to or less than the length (vertical length) L1 of the slit portion 81 (see FIGS. 7A to 7C). By making the vertical interval L2 between the slit portions 81 as small as possible, the effect of suppressing the cooling sensation agent from exuding outward in the width direction of the absorbent layer 3 becomes higher. From the viewpoint of suppressing the exudation of the cooling sensation agent, the distance L2 between the slit portions 81 and 81 means the length of the continuous portion where the absorption layer 3 is not broken as the entire slit portion region 86. When the slit part region 86 has a plurality of slit part rows 85, the whole is regarded as one row and the interval L2 is grasped.

図７（Ａ）に示すように、１つのスリット部列８５Ａが配されている場合は、スリット部８１、８１間の間隔Ｌ２を、スリット部８１の縦方向の長さＬ１以下にする（Ｌ２≦Ｌ１）ことが好ましい。吸収層３の強度の保持、ヨレ防止の観点から、１列に並ぶスリット部８１同士が連結されないよう、間隔Ｌ２は０（ゼロ）超であることが好ましい。   As shown in FIG. 7A, when one slit portion row 85A is arranged, the interval L2 between the slit portions 81, 81 is set to be equal to or less than the longitudinal length L1 of the slit portion 81 (L2 ≦ L1) is preferable. From the viewpoint of maintaining the strength of the absorption layer 3 and preventing twisting, it is preferable that the interval L2 is greater than 0 (zero) so that the slit portions 81 arranged in a row are not connected to each other.

また、図７（Ｂ）に示すように、並列するスリット部列８５Ａ、８５Ｂ、８５Ｃが配されている場合は、スリット部列同士で幅方向に隣り合うスリット部８１、８１間の縦方向の間隔Ｌ２を、スリット部８１の縦方向の長さＬ１以下にする（Ｌ２≦Ｌ１）ことが好ましい。ここで言うスリット部８１、８１間の縦方向の間隔Ｌ２は、言い換えると、１つのスリット部列に他のスリット部列を投影（例えば、スリット部列８５Ａにスリット部列８５Ｂ及び８５Ｃを投影）してみたときの間隔Ｌ２を意味する。そのため、１つのスリット部列について、スリット部８１、８１間の縦方向の間隔Ｌ２がスリット部８１の縦方向の長さＬ１を超えることがあっても上記の条件を満たせばよい。これにより、スリット部列同士で連携して冷感剤の幅方向に滲出することを抑制することができる。この場合、異なる列同士において隣り合うスリット部８１、８１の間隔Ｌ２が０（ゼロ）となる部分があってもよい。特に、図７（Ｃ）に示すように、異なる列同士において隣り合うスリット部８１、８１の縦方向の間隔Ｌ２を全て０（ゼロ）とすることが好ましい。これにより、スリット部領域８６において、縦方向に対し幅方向に横断するいずれの仮想線上においてもスリット部８１が存在し、冷感剤の幅方向の滲出に対する抑制効果がより高くなる。   Further, as shown in FIG. 7B, when the parallel slit part rows 85A, 85B, and 85C are arranged, the vertical direction between the slit parts 81 and 81 adjacent to each other in the width direction in the slit part rows. The interval L2 is preferably set to be equal to or less than the length L1 in the vertical direction of the slit portion 81 (L2 ≦ L1). In other words, the vertical distance L2 between the slit portions 81 and 81 is that the other slit portion rows are projected onto one slit portion row (for example, the slit portion rows 85B and 85C are projected onto the slit portion row 85A). It means the interval L2 when trying. For this reason, even if the vertical interval L2 between the slit portions 81, 81 exceeds the vertical length L1 of the slit portion 81 for one slit portion row, the above-described conditions may be satisfied. Thereby, it can suppress that a slit part row | line | column cooperates and it exudes in the width direction of a cooling sensation agent. In this case, there may be a portion where the interval L2 between the adjacent slit portions 81 and 81 in different rows is 0 (zero). In particular, as shown in FIG. 7C, it is preferable that all the vertical intervals L2 of the slit portions 81 and 81 adjacent to each other in different columns be 0 (zero). Thereby, in the slit part area | region 86, the slit part 81 exists on any imaginary line which cross | intersects the width direction with respect to the vertical direction, and the inhibitory effect with respect to the exudation of the cooling agent in the width direction becomes higher.

吸収層３は、断面視において、図８に示すように、ポリマーリッチ領域３５と繊維リッチ領域３６とを備えることが好ましい。具体的には、図８は、吸収層３を構成する折り畳まれた吸収性シートの一部の厚み断面にポリマーリッチ領域３５と繊維リッチ領域３６とが積層されて一体構造となっている態様を示している。
ポリマーリッチ領域３５と繊維リッチ領域３６とは、高吸収性ポリマー材３７の質量と親水性繊維の質量との合計質量に対する高吸収性ポリマー材３７の質量比率（以下、単に「高吸収性ポリマー材３７の質量比率」と言う。）によって規定される。ポリマーリッチ領域３５は繊維リッチ領域３６よりも前記高吸収性ポリマー材３７の質量比率が相対的に高くされている。一方、繊維リッチ領域３６は、高吸収性ポリマー材３７の質量比率がポリマーリッチ領域３５に対し相対的に低くされている。The absorbent layer 3 preferably includes a polymer-rich region 35 and a fiber-rich region 36 as shown in FIG. Specifically, FIG. 8 shows an aspect in which a polymer-rich region 35 and a fiber-rich region 36 are laminated on a part of the thickness cross section of the folded absorbent sheet constituting the absorbent layer 3 to form an integrated structure. Show.
The polymer-rich region 35 and the fiber-rich region 36 are the mass ratio of the superabsorbent polymer material 37 to the total mass of the superabsorbent polymer material 37 and the hydrophilic fiber (hereinafter simply referred to as “superabsorbent polymer material”). 37 mass ratio ”)). The mass ratio of the superabsorbent polymer material 37 in the polymer rich region 35 is relatively higher than that in the fiber rich region 36. On the other hand, in the fiber rich region 36, the mass ratio of the superabsorbent polymer material 37 is relatively low with respect to the polymer rich region 35.

繊維リッチ領域３６の厚みは、吸収層３の全厚みに対して、１／１０以上７／１０以下、特に１／３以上２／３以下であることが、体液の拡散性と保持性の観点から好ましい。
また、一体化構造のように、ポリマーリッチ領域３５と繊維リッチ領域３６の境界が明確ではない吸収層３の構造の場合には、その厚みを２等分した場合に一方の厚み領域と他方の厚み領域とを比較して、高吸収性ポリマー材の質量比率が相対的に大きい方をポリマーリッチ領域３５、親水性繊維の質量比率が相対的に大きい方を繊維リッチ領域３６とする。The fiber-rich region 36 has a thickness of 1/10 or more and 7/10 or less, particularly 1/3 or more and 2/3 or less, with respect to the total thickness of the absorbent layer 3, from the viewpoint of diffusibility and retention of body fluids. To preferred.
Further, in the case of the structure of the absorption layer 3 where the boundary between the polymer rich region 35 and the fiber rich region 36 is not clear as in the integrated structure, when the thickness is divided into two equal parts, Compared with the thickness region, a relatively large mass ratio of the superabsorbent polymer material is defined as a polymer rich region 35, and a relatively large mass ratio of hydrophilic fibers is defined as a fiber rich region 36.

吸収層３は上記構成により、吸収層３の厚み方向において、吸収後に自由水が相対的に少なくなるポリマーリッチ領域３５と自由水が相対的に多く残る繊維リッチ領域３６とを備え、冷感剤を肌に届ける異なる機構を備える。
具体的には、ポリマーリッチ領域３５は、自由水が相対的に少ないため、冷感剤が適度に揮発できる環境を提供する。この環境下においてポリマーリッチ領域３５で揮発した冷感剤の成分は、スリット部８１（分断部８）の作用によって肌へと送られる。一方、繊維リッチ領域３６は、自由水が多く残るため、冷感剤が水溶性カプセルや剤を送給するためのデリバリーシステムとともに使用される場合に、液の移動に合わせて肌に冷感を付与することができる。また、繊維リッチ領域３５は、冷感剤の揮発を抑制的に発現させることができる。
これにより、冷感剤を、ポリマーリッチ領域３５及び繊維リッチ領域３６のいずれかに優先的に含ませることで、吸液性及び冷感付与性等を好適に制御し得る。The absorbent layer 3 is provided with a polymer-rich region 35 in which free water is relatively reduced after absorption and a fiber-rich region 36 in which a relatively large amount of free water remains in the thickness direction of the absorbent layer 3 in the thickness direction of the absorbent layer 3. Equipped with different mechanisms to deliver to the skin.
Specifically, the polymer-rich region 35 provides an environment in which the cooling sensation agent can be appropriately volatilized because there is relatively little free water. The components of the cooling sensitizer volatilized in the polymer-rich region 35 under this environment are sent to the skin by the action of the slit portion 81 (dividing portion 8). On the other hand, since the fiber-rich region 36 has a large amount of free water, when the cooling sensation agent is used with a delivery system for delivering water-soluble capsules or agents, the skin feels cool as the liquid moves. Can be granted. Further, the fiber rich region 35 can suppress the volatilization of the cooling sensation agent.
Thereby, by including a cooling sensation preferentially in either the polymer rich area | region 35 or the fiber rich area | region 36, liquid absorptivity, a cool feeling provision property, etc. can be controlled suitably.

ポリマーリッチ領域３５が冷感剤を含み、該ポリマーリッチ領域３５が繊維リッチ領域３６よりも非肌面側に配される構成であると、繊維リッチ領域３６及び該領域内の自由水によって、ポリマーリッチ領域３５内で冷感剤が揮発した成分が拡散するのを適度に抑えることができる。これにより冷感効果を長持ちさせることができる。その際、スリット部８１は、少なくとも吸収層３の肌面側から繊維リッチ領域３６、ポリマーリッチ領域３５を貫通して配されていることが好ましい。   When the polymer rich region 35 includes a cooling sensation agent and the polymer rich region 35 is arranged on the non-skin surface side of the fiber rich region 36, the polymer rich region 36 and free water in the region cause a polymer. It is possible to moderately suppress the diffusion of the component in which the cooling sensitizer volatilizes in the rich region 35. Thereby, the cool feeling effect can be prolonged. In that case, it is preferable that the slit part 81 is distribute | arranged and penetrated the fiber rich area | region 36 and the polymer rich area | region 35 from the skin surface side of the absorption layer 3 at least.

他方で、繊維リッチ領域３６が冷感剤を含む領域を有し、該冷感剤を含む領域が吸収層３の最も表面層１側（肌面側）に配されていると冷感を感じやすくなる。この場合、繊維リッチ領域３６が冷感剤を抑制的に揮発させる。表面層１に近い位置において、冷感剤の含有量を低減させながら刺激を抑え、冷感効果をより好適なものとなるよう制御するこができ好ましい。   On the other hand, when the fiber-rich region 36 has a region containing a cooling sensation, and the region containing the cooling sensation is arranged on the most surface layer 1 side (skin surface side) of the absorbent layer 3, a feeling of cooling is felt. It becomes easy. In this case, the fiber rich region 36 volatilizes the cooling sensation inhibitoryly. Stimulation is suppressed while reducing the content of the cooling sensation agent at a position close to the surface layer 1, and the cooling effect can be controlled to be more preferable.

図８に示したポリマーリッチ領域３５と繊維リッチ領域３６とがシート厚みにおいて上下に積層される態様は、吸収層３の折り畳まれた本体吸収性シート３１及び中央吸収性シート３２の全体にあってもよく、一部にあってもよい。また、ポリマーリッチ領域３５と繊維リッチ領域３６とは、図８に示す態様の他、吸収層３を構成する吸収性シートの折り畳み構造おける別々の部位に配されてもよい。肌への過度な刺激を抑制し、適度な冷感効果を長く維持させる観点から、吸収性シートの同一部位に厚み方向に積層されて配されることが好ましい。少なくとも吸収層３の最も表面層１側（肌面側）のシート部分（本体吸収性シート３１の肌面側部分３１Ａ）において、繊維リッチ領域３６、ポリマーリッチ領域３５の順で積層されていることが好ましい。   The mode in which the polymer rich region 35 and the fiber rich region 36 shown in FIG. 8 are stacked one above the other in the sheet thickness is the entirety of the folded main body absorbent sheet 31 and central absorbent sheet 32 of the absorbent layer 3. Or part of it. Further, the polymer-rich region 35 and the fiber-rich region 36 may be arranged at different sites in the folded structure of the absorbent sheet constituting the absorbent layer 3 in addition to the embodiment shown in FIG. From the viewpoint of suppressing excessive irritation to the skin and maintaining a moderate cooling sensation effect for a long time, it is preferable to be laminated in the thickness direction on the same part of the absorbent sheet. The fiber-rich region 36 and the polymer-rich region 35 are laminated in this order at least in the sheet portion on the most surface layer 1 side (skin surface side) of the absorbent layer 3 (skin surface side portion 31A of the main body absorbent sheet 31). Is preferred.

吸収性シートにおけるポリマーリッチ領域３５と繊維リッチ領域３６の形成は、例えば次のようにして行うことができる。
まず、親水性繊維を含む水スラリーを湿式抄紙して抄造された、湿潤した繊維ウエブを作製する。水スラリーには熱溶融性接着繊維、紙力補強剤などを含ませてもよい。湿潤した状態にある繊維ウエブに対して、高吸収性ポリマー材を散布し、高吸収性ポリマーが繊維間に入り込んだ状態を作り出す。この部分が、吸収性シートにおけるポリマーリッチ領域３５となる。次いで、高吸収性ポリマーを散布した面の上から、親水性繊維及び熱溶融性接着繊維又は紙力補強剤を含む繊維集合体を積層して乾燥、一体化処理をして吸収性シートを得る。後から積層した繊維集合体の部分が繊維リッチ領域３６となる。
また、吸収性シートを乾式で作製する場合は、高吸収性ポリマー材を散布する層は、抄紙、乾燥した紙、種々の方法により作製された不織布であってもよい。高吸収性ポリマー材を繊維間に入り込ませやすくするという観点から、クレープ処理されたような嵩高な紙、エアースルー不織布などが好ましい。この場合、高吸収性ポリマー材とポリマーリッチ領域３５となる層の構成繊維との接合、ポリマーリッチ領域３５となる層と繊維リッチ領域３６となる層との接合には、ホットメルト型接着剤や水溶性接着剤などを用いてもよい。さらに、ポリマーリッチ領域３５となる層に対し、親水性繊維を積層する又は吹き付けることで繊維リッチ領域３６を形成してもよい。Formation of the polymer rich region 35 and the fiber rich region 36 in the absorbent sheet can be performed, for example, as follows.
First, a wet fiber web made by wet papermaking of an aqueous slurry containing hydrophilic fibers is prepared. The water slurry may contain hot-melt adhesive fibers, paper strength reinforcing agents, and the like. A superabsorbent polymer material is sprayed on the wet fiber web to create a state in which the superabsorbent polymer enters between the fibers. This portion becomes the polymer rich region 35 in the absorbent sheet. Next, a fiber assembly containing hydrophilic fibers and heat-meltable adhesive fibers or paper strength reinforcing agents is laminated on the surface on which the superabsorbent polymer is dispersed, dried and integrated to obtain an absorbent sheet. . The portion of the fiber assembly laminated later becomes the fiber rich region 36.
When the absorbent sheet is produced by a dry method, the layer to which the superabsorbent polymer material is dispersed may be paper making, dried paper, or a nonwoven fabric produced by various methods. From the viewpoint of facilitating the entry of the superabsorbent polymer material between fibers, bulky paper such as creped, air-through nonwoven fabric, and the like are preferable. In this case, for bonding the superabsorbent polymer material and the constituent fibers of the layer that becomes the polymer-rich region 35, and bonding the layer that becomes the polymer-rich region 35 and the layer that becomes the fiber-rich region 36, a hot melt adhesive or A water-soluble adhesive or the like may be used. Further, the fiber-rich region 36 may be formed by laminating or spraying hydrophilic fibers on the layer that becomes the polymer-rich region 35.

次に、本発明の吸収性物品の好ましい製造方法について説明する。
好ましい製造方法としては、通常用いられる吸収性物品の製造方法の中で、吸収層３の形成工程において次の工程を有する。
すなわち、吸収層となる原料部材の所定幅に亘って冷感剤を塗布する工程（Ｓ１）と、吸収層となる原料部材の表面に冷感剤塗布幅よりも広い幅に亘って吸収層の縦方向に延びる分断部領域を設ける工程（Ｓ２）とを備える。Next, the preferable manufacturing method of the absorbent article of this invention is demonstrated.
As a preferable manufacturing method, the following steps are included in the forming step of the absorbent layer 3 in the manufacturing method of the absorbent article that is usually used.
That is, a step (S1) of applying a cooling sensation agent over a predetermined width of the raw material member to be the absorption layer, and a surface of the raw material member to be the absorption layer on the surface of the absorption layer over a width wider than the cooling sensitizer application width. And a step (S2) of providing a dividing portion region extending in the vertical direction.

工程（Ｓ１）において、冷感剤を塗布する幅は、前述した吸収層３の幅方向両端縁３９よりも内側となる領域であることが好ましい。吸収層３の幅に対して例えば７５％以下の範囲となる領域であることがより好ましい。吸収層３となる原料部材が吸収性シート部材である場合には、後述する工程（Ｓ３）の様に折り畳んで積層吸収性シートを形成することがある。そのときは、積層吸収性シートの一の面の幅が上述する吸収層３の幅となる。工程（Ｓ１）において、冷感剤は、溶媒を混合した冷感剤溶液（塗布液）として調製し、塗布する。溶媒としては通常用い得るものを採用することができ、例えば、ジプロピレングリコールなどが挙げられる。
工程（Ｓ２）において、分断部８を形成する領域の幅は、冷感剤塗布幅よりも広く、かつ、前述した吸収層３の幅方向両端縁３９よりも内側となる領域であることが好ましい。吸収層３の幅に対して例えば８５％以下の範囲となる領域であることがより好ましい。
また、工程（Ｓ１）及び工程（Ｓ２）のいずれにおいても、吸収層３となる原料部材の、少なくとも中間部Ｃとなる領域に対して加工処理を行うことが好ましい。In the step (S1), it is preferable that the width to which the cooling sensation agent is applied is a region which is on the inner side of the both end edges 39 of the absorption layer 3 in the width direction. It is more preferable that the region be within a range of, for example, 75% or less with respect to the width of the absorption layer 3. When the raw material member used as the absorption layer 3 is an absorptive sheet member, it may be folded like the process (S3) mentioned later, and a laminated absorbent sheet may be formed. At that time, the width of one surface of the laminated absorbent sheet is the width of the absorbent layer 3 described above. In the step (S1), the cooling sensation agent is prepared and applied as a cooling sensation agent solution (coating solution) mixed with a solvent. As the solvent, those which can be usually used can be employed, and examples thereof include dipropylene glycol.
In the step (S2), the width of the region for forming the dividing portion 8 is preferably a region that is wider than the cooling agent application width and that is inside the both end edges 39 in the width direction of the absorbent layer 3 described above. . It is more preferable that the region be in a range of, for example, 85% or less with respect to the width of the absorption layer 3.
Moreover, in any of the step (S1) and the step (S2), it is preferable to perform the processing on at least the region that becomes the intermediate portion C of the raw material member that becomes the absorption layer 3.

工程（Ｓ１）と工程（Ｓ２）とはどちらが先に行われてもよい。ただし、工程（Ｓ２）の後に、工程（Ｓ１）が行われると、より確実に幅方向両端縁３９への冷感剤の拡散が抑制されることとなり好ましい。   Either step (S1) or step (S2) may be performed first. However, when the step (S1) is performed after the step (S2), it is preferable because the diffusion of the cooling sensation agent to the both edges 39 in the width direction is more reliably suppressed.

また、工程（Ｓ２）は、分断部８として切り込み（スリット部８１）を形成する工程であることが好ましい。これにより、分断部８の形成を、所望の配置及び深さで精度よく行うことができる。
より具体的には、吸収層となる原料部材が吸収性シート部材であり、折り畳まれることを想定して吸収層３の幅よりも幅広のものを用いる。該吸収性シートの所定の領域に複数の切り込み（スリット部８１）を、面方向に分散配置して設ける。吸収性シートに設ける切り込みは、図３に示すように、吸収層３の縦方向に延びる長さを有して、該縦方向に複数配列されることが好ましく、切り込みの縦方向の配列を吸収層３の幅方向に複数配列することがより好ましい。このとき、前述のとおり、縦方向に並ぶ切り込み間の間隔を該切り込みの長さ以下にすることが更に好ましい。Moreover, it is preferable that a process (S2) is a process of forming the notch (slit part 81) as the parting part 8. FIG. Thereby, formation of the parting part 8 can be accurately performed with a desired arrangement and depth.
More specifically, the raw material member to be the absorption layer is an absorbent sheet member, and a material wider than the width of the absorption layer 3 is used assuming that the material is folded. A plurality of cuts (slit portions 81) are provided in a predetermined area of the absorbent sheet in a distributed manner in the plane direction. As shown in FIG. 3, the cuts provided in the absorbent sheet have a length extending in the vertical direction of the absorbent layer 3, and a plurality of cuts are preferably arranged in the vertical direction, absorbing the vertical arrangement of the cuts. More preferably, a plurality of layers 3 are arranged in the width direction. At this time, as described above, it is more preferable that the interval between the cuts arranged in the vertical direction is equal to or less than the length of the cut.

切り込み（スリット部８１）の形成は、この種の物品に通常用いられる方法によって行うことができる。例えば、ロール周面に、周方向に延びる切断刃が、ロール周方向及びロール軸方向に分散配置されたカッターロールと、対応配置されるアンビルロールとを備えた切断装置を用いて切り込みを形成することができる（図示せず）。前記切断刃は、切り込み（スリット部８１）の縦方向の長さに対応する周方向の長さを有する。この切断刃は、ロール周面において、切り込み（スリット部８１）の所望の配置に対応して分散配置される。また、切り込みの深さは、カッターロールとアンビルロールとのクリアランスや切断刃の大きさ等によって設定することができる。   The cut (slit portion 81) can be formed by a method usually used for this type of article. For example, cutting blades extending in the circumferential direction on the circumferential surface of the roll form a cut using a cutting device provided with cutter rolls arranged in a distributed manner in the roll circumferential direction and roll axial direction and anvil rolls arranged correspondingly. (Not shown). The cutting blade has a circumferential length corresponding to the longitudinal length of the cut (slit portion 81). The cutting blades are distributed and arranged on the roll peripheral surface in correspondence with the desired arrangement of the cuts (slit portions 81). Further, the depth of cutting can be set by the clearance between the cutter roll and the anvil roll, the size of the cutting blade, and the like.

さらに、吸収層３となる原料部材が吸収性シート部材である場合には、次の工程を有することが好ましい。
すなわち、工程（Ｓ１）及び工程（Ｓ２）の後、吸収性シート部材を冷感剤を塗布した位置の幅方向端よりも外側で折り畳んで積層吸収性シートを形成する工程（Ｓ３）を備えることが好ましい。これにより、吸収性シートが折り畳まれて積層構造となった吸収層３が得られる。冷感剤塗布位置の幅方向端よりも外側で折り畳むことによって、前述のように吸収層３の幅方向両端縁３９よりも内側の領域に冷感剤が含まれることとなり好ましい。
また、工程（Ｓ３）において吸収性シートを折り畳むことによって、製造の過程において、冷感剤の幅方向の滲出しすぎを抑制することができ好ましい。更に吸収性シートが折り畳まれて積層構造となることで、前述のとおり、分断部の作用によって奏する肌への適度な冷感効果をより長く効果的に維持することができる吸収性物品となるため好ましい。Furthermore, when the raw material member used as the absorption layer 3 is an absorptive sheet member, it is preferable to have the following process.
That is, after the step (S1) and the step (S2), a step (S3) of forming the laminated absorbent sheet by folding the absorbent sheet member outside the width direction end of the position where the cooling sensation agent is applied is provided. Is preferred. Thereby, the absorption layer 3 by which the absorbent sheet was folded and became a laminated structure is obtained. Folding outside the width direction end of the cooling sensation application position is preferable because the cooling sensation agent is contained in the region inside the width direction end edges 39 of the absorbent layer 3 as described above.
In addition, it is preferable to fold the absorbent sheet in the step (S3), so that excessive exudation of the cooling agent in the width direction can be suppressed in the manufacturing process. Furthermore, since the absorbent sheet is folded to form a laminated structure, as described above, the absorbent article can maintain an appropriate cooling effect on the skin produced by the action of the dividing portion for a longer time. preferable.

工程（Ｓ３）においては、吸収性シートの折り畳む幅方向の位置を、分断部８領域の幅方向端よりも外側とすることが更に好ましい。   In the step (S3), it is more preferable that the position in the width direction in which the absorbent sheet is folded is outside the width direction end of the divided portion 8 region.

吸収性シートが折り畳まれた積層構造としては、二つ折り、三つ折り等など種々の態様とすることができる。三つ折りとしては、吸収性シートの幅方向両端部を重ね合わせることが好ましい。これにより、冷感剤の揮発成分の溜りを形成しやすく、分断部８による肌への送り込みをより効果的することができる。その際、吸収性シートの冷感剤塗布面を外側にして折り畳むことがより好ましい。また、吸収性シートが前述したようにポリマーリッチ領域３５と繊維リッチ領域３６とを有する場合、繊維リッチ領域３６に冷感剤を塗布して、繊維リッチ領域３６の冷感剤を塗布した領域を外側にして折り畳むことが更に好ましい。   As a laminated structure in which the absorbent sheet is folded, various modes such as bi-fold and tri-fold can be used. As tri-folding, it is preferable to overlap the both ends of the absorbent sheet in the width direction. Thereby, it is easy to form a pool of volatile components of the cooling sensation agent, and the feeding to the skin by the dividing portion 8 can be made more effective. In that case, it is more preferable to fold the absorbent sheet with the cooling agent-coated surface facing outward. Further, when the absorbent sheet has the polymer-rich region 35 and the fiber-rich region 36 as described above, the cooling sensation agent is applied to the fiber-rich region 36, and the region where the cooling sensation agent is applied to the fiber-rich region 36. More preferably, it is folded outward.

また、吸収性シートとして、幅の異なる複数種類のものを用いてもよい。
例えば、幅の異なる２種類の吸収性シートを用いて、図２に示すように、本体吸収性シート３１の折り畳み構造の内部に中央吸収性シート３２を内包するようにしてもよい。その際、工程（Ｓ１）における冷感剤は、いずれの吸収性シートに塗布してもよい。ただし、冷感剤の厚み方向への滲出の抑制と、分断部８の作用による冷感効果の長く効果的な維持とをより優れたものとする観点から、本体吸収性シート３１となる、幅広の吸収性シートに冷感剤を塗布することが好ましい。Further, as the absorbent sheet, a plurality of types having different widths may be used.
