Description

本発明は、吸収性物品の個包装体に関する。 The present invention relates to an individual package of an absorbent article.

吸収性物品を、個包装シート上に配置した状態で、個包装シートと共に複数回折り畳むことにより個別に包装した、吸収性物品の個包装体が知られている。例えば、特許文献1(特許第5922969号)には、吸収性物品と個包装シートとを備える、吸収性物品の個包装体が開示されている。この個包装体は、吸収性物品が、個包装シートと共に、2本の長手方向折線の位置で折り畳まれ、次いで、2本の幅方向折線の位置で折り畳まれた後、長手方向に延びる粘着テープで個包装シートの端部が個包装シートの他の部分に固定された構成を有している。 There is known an individually wrapped body of an absorbent article in which the absorbent article is individually wrapped by being folded a plurality of times together with the individual wrapping sheet in a state of being arranged on the individual wrapping sheet. For example, Patent Document 1 (Patent No. 59221969) discloses an individually wrapped body of an absorbent article, which comprises the absorbent article and the individually wrapped sheet. This individually wrapped body is an adhesive tape in which the absorbent article is folded together with the individual packaging sheet at the positions of two longitudinal fold lines, then folded at the positions of two widthwise fold lines, and then extends in the longitudinal direction. The end of the individual wrapping sheet is fixed to the other part of the individual wrapping sheet.

Specifically, the disclosure of the present invention relates to the following aspects.
[Aspect 1]
It has a longitudinal direction, a width direction, and a thickness direction orthogonal to each other, includes an individual wrapping sheet and an absorbent article, and the absorbent article is placed on the individual wrapping sheet. An individual package that is folded and packaged together with a packaging sheet, and has a first width that is provided on one end side in the width direction and is folded in the width direction with a first longitudinal folding line along the longitudinal direction as a base point. A second widthwise folded portion folded in the width direction and a second widthwise folded portion provided on the other end side in the width direction and folded in the width direction with a second longitudinal folding line along the longitudinal direction as a base point, and the first width direction. In a state where the folded portion and the second width direction folded portion are folded, the first folded portion in the longitudinal direction is provided on one end side in the longitudinal direction and is folded in the longitudinal direction with the first width direction folding line along the width direction as a base point. In a state where the longitudinal folding portion, the first width direction folding portion, and the second width direction folding portion are folded, a second width direction folding line provided on the other end side in the longitudinal direction and along the width direction is formed. The base point has a second longitudinal folding portion folded in the longitudinal direction, and the first end portion of the first longitudinal folding portion on the side of the first width direction folding line is opposite to the first end portion in the longitudinal direction. An adhesive tape having one end bonded to the surface of the second end portion located on the side and the other end bonded to the surface of the second longitudinal folding portion is provided, and the first longitudinal folding portion has the width. In the direction, the rigidity of each of the pair of side portions includes a pair of side portions located on both sides of the adhesive tape and an intermediate portion located between the pair of side portions, and the rigidity of each of the pair of side portions is the rigidity of the intermediate portion. Higher than, individually wrapped.

使用者が一方の手で個包装体を幅方向に把持することで、個包装体に、その幅方向の両端部から中央部に向かう力が加わる場合がある。その場合、加わった力の大きさが強過ぎるときには、個包装体、したがって第1長手方向折り畳み部及び第2長手方向折り畳み部のいずれも手のひらの形状に沿って、略凹状に変形してしまう状況が生じ得る。そうなると、粘着テープを上手に摘まむことが困難になるおそれがある。そこで、本請求項1に記載の吸収性物品では、第1長手方向折り畳み部において、粘着テープの両側に位置する一対の側部の各々の剛性を、一対の側部の間に位置する中間部の剛性よりも高くしている。そのため、第1長手方向折り畳み部に幅方向の両端部から中央部に向かう力が加わったとき、剛性の高い各側部は変形し難く、剛性の低い中間部が変形し易くなる。ただし、中間部は粘着テープで第2長手方向折り畳み部に固定されてやや変形し難いため、一対の側部と中間部との境界付近の部分が主に変形することになる。具体的には、長手方向から見て、第1長手方向折り畳み部のうち、一対の側部と中間部との境界付近の部分が変形することで、中間部を基点として、一対の側部における、個包装体の幅方向の両端部に対応する部分が立ち上がって、略V字の形状が形成される。このとき、第2長手方向折り畳み部は略凹状に変形するが、その幅方向の外側の部分の立ち上がりは少ない。そのため、第2長手方向折り畳み部と一対の側部の各々との間に隙間が生じる。これらの隙間が生じると、使用者は、自然に、いずれかの隙間に指を挿入して、その側部を摘まんで、第2長手方向折り畳み部から引き離すことで、粘着テープを剥離しようとする。ここで、一対の側部の各々は、相対的に剛性が高いので、その引き離そうとする力を粘着テープに容易に伝達することができる。それにより、使用者は、隙間に指を挿入して、側部を摘まんで、粘着テープを剥離させて、容易に、個包装体を開封することが可能となる。
すなわち、吸収性物品の個包装体において、一方の手で把持して、他方の手で開封する際にも、開封し易い個包装体を提供することができる。
When the user grips the individual package in the width direction with one hand, a force may be applied to the individual package from both ends in the width direction toward the center. In that case, when the applied force is too strong, the individual package, and therefore both the first longitudinal folding portion and the second longitudinal folding portion are deformed substantially concavely along the shape of the palm. Can occur. In that case, it may be difficult to pick the adhesive tape well. Therefore, in the absorbent article according to claim 1, in the first longitudinal folding portion, the rigidity of each of the pair of side portions located on both sides of the adhesive tape is set to the intermediate portion located between the pair of side portions. It is higher than the rigidity of. Therefore, when a force is applied to the first longitudinally folded portion from both end portions in the width direction toward the central portion, each side portion having high rigidity is difficult to be deformed, and the intermediate portion having low rigidity is easily deformed. However, since the intermediate portion is fixed to the second longitudinal folding portion with an adhesive tape and is somewhat difficult to deform, the portion near the boundary between the pair of side portions and the intermediate portion is mainly deformed. Specifically, when viewed from the longitudinal direction, the portion of the first longitudinally folded portion near the boundary between the pair of side portions and the intermediate portion is deformed, so that the intermediate portion is used as a base point and the pair of side portions is formed. , The portions corresponding to both ends in the width direction of the individual package stand up to form a substantially V-shape. At this time, the second longitudinally folded portion is deformed in a substantially concave shape, but the rising portion of the outer portion in the width direction is small. Therefore, a gap is generated between each of the second longitudinal folding portion and the pair of side portions. When these gaps occur, the user naturally attempts to peel off the adhesive tape by inserting a finger into one of the gaps, pinching the side portion, and pulling it away from the second longitudinal folding portion. .. Here, since each of the pair of side portions has relatively high rigidity, the force for pulling them apart can be easily transmitted to the adhesive tape. As a result, the user can easily open the individual package by inserting a finger into the gap, pinching the side portion, and peeling off the adhesive tape.
That is, in an individual package of an absorbent article, it is possible to provide an individual package that is easy to open even when it is gripped by one hand and opened by the other hand.

[態様2]
前記一対の側部の各々に配置された補強部材を更に備える、態様1に記載の個包装体。
本個包装体では、一対の側部の各々の内部に補強部材が配置されているので、一対の側部の剛性を確実に高くすることができる。それにより、一対の側部を確実に立ち上がらせることができると共に、側部を摘んで第2長手方向折り畳み部から引き離そうとする力を加えたとき、その力を粘着テープに確実に伝達することができる。すなわち、使用者は、隙間に指を挿入して、側部を摘まんで、粘着テープを剥離させて、容易に、個包装体を開封することが可能となる。
[Aspect 2]
The individual package according to aspect 1, further comprising a reinforcing member arranged on each of the pair of side portions.
In this individual package, since the reinforcing members are arranged inside each of the pair of side portions, the rigidity of the pair of side portions can be surely increased. As a result, the pair of side portions can be reliably raised, and when a force is applied to pick the side portions and pull them away from the second longitudinal folding portion, the force can be reliably transmitted to the adhesive tape. it can. That is, the user can easily open the individual package by inserting a finger into the gap, pinching the side portion, and peeling off the adhesive tape.

In the direction, the pair of side portions includes a pair of side portions located on both sides of the adhesive tape and an intermediate portion located between the pair of side portions and in contact with at least one of the pair of side portions. An individual package further comprising a reinforcing member arranged in each of the above.

使用者が一方の手で個包装体を幅方向に把持することで、個包装体に、その幅方向の両端部から中央部に向かう力が加わる場合がある。その場合、加わった力の大きさが強過ぎるときには、個包装体、したがって第1長手方向折り畳み部及び第2長手方向折り畳み部のいずれも手のひらの形状に沿って、略凹状に変形してしまう状況が生じ得る。そうなると、粘着テープを上手に摘まむことが困難になるおそれがある。そこで、本請求項3に記載の吸収性物品では、第1長手方向折り畳み部において、粘着テープの両側に位置する一対の側部の各々に、補強部材を配置している。そのため、第1長手方向折り畳み部に幅方向の両端部から中央部に向かう力が加わったとき、補強部材を含む各側部は変形し難く、補強部材を含まない中間部が変形し易くなる。ただし、中間部は粘着テープで第2長手方向折り畳み部に固定されてやや変形し難いため、一対の側部と中間部との境界付近の部分が主に変形することになる。具体的には、長手方向から見て、第1長手方向折り畳み部のうち、一対の側部と中間部との境界付近の部分が変形することで、中間部を基点として、一対の側部における、個包装体の幅方向の両端部に対応する部分が立ち上がって、略V字の形状が形成される。このとき、第2長手方向折り畳み部は略凹状に変形するが、その幅方向の外側の部分の立ち上がりは少ない。そのため、第2長手方向折り畳み部と一対の側部の各々との間に隙間が生じる。これらの隙間が生じると、使用者は、自然に、いずれかの隙間に指を挿入して、その側部を摘まんで、第2長手方向折り畳み部から引き離すことで、粘着テープを剥離しようとする。ここで、一対の側部の各々は、補強部材を含むので、その引き離そうとする力を粘着テープに容易に伝達することができる。それにより、使用者は、隙間に指を挿入して、側部を摘まんで、粘着テープを剥離させて、容易に、個包装体を開封することが可能となる。
すなわち、吸収性物品の個包装体において、一方の手で把持して、他方の手で開封する際にも、開封し易い個包装体を提供することができる。
When the user grips the individual package in the width direction with one hand, a force may be applied to the individual package from both ends in the width direction toward the center. In that case, when the applied force is too strong, the individual package, and therefore both the first longitudinal folding portion and the second longitudinal folding portion are deformed substantially concavely along the shape of the palm. Can occur. In that case, it may be difficult to pick the adhesive tape well. Therefore, in the absorbent article according to claim 3, reinforcing members are arranged on each of the pair of side portions located on both sides of the adhesive tape in the first longitudinal folding portion. Therefore, when a force is applied to the first longitudinally folded portion from both end portions in the width direction toward the central portion, each side portion including the reinforcing member is difficult to be deformed, and the intermediate portion not including the reinforcing member is easily deformed. However, since the intermediate portion is fixed to the second longitudinal folding portion with an adhesive tape and is somewhat difficult to deform, the portion near the boundary between the pair of side portions and the intermediate portion is mainly deformed. Specifically, when viewed from the longitudinal direction, the portion of the first longitudinally folded portion near the boundary between the pair of side portions and the intermediate portion is deformed, so that the intermediate portion is used as a base point and the pair of side portions is formed. , The portions corresponding to both ends in the width direction of the individual package stand up to form a substantially V-shape. At this time, the second longitudinally folded portion is deformed in a substantially concave shape, but the rising portion of the outer portion in the width direction is small. Therefore, a gap is generated between each of the second longitudinal folding portion and the pair of side portions. When these gaps occur, the user naturally attempts to peel off the adhesive tape by inserting a finger into one of the gaps, pinching the side portion, and pulling it away from the second longitudinal folding portion. .. Here, since each of the pair of side portions includes a reinforcing member, the force to pull them apart can be easily transmitted to the adhesive tape. As a result, the user can easily open the individual package by inserting a finger into the gap, pinching the side portion, and peeling off the adhesive tape.
That is, in an individual package of an absorbent article, it is possible to provide an individual package that is easy to open even when it is gripped by one hand and opened by the other hand.

本実施形態に係る生理用ナプキン1の個包装体Pの構成例について説明する。
図1〜図3は本実施形態に係る個包装体P(展開した状態)の構成例を示す図である。図1は、生理用ナプキン1の個包装体P(展開した状態)の構成例を示す平面図である。図2は、図1に示す生理用ナプキン1における長手方向中心線CL(後述)に沿った断面図である。図3は、図1に示す生理用ナプキン1を示す下面図である。個包装体Pは、個包装シート43と、生理用ナプキン1と、を備え、生理用ナプキン1が、個包装シート43上に載置された状態で、個包装シート43と共に折り畳まれて包装された構成を有する。ただし、個包装体Pは、図1に示すように、展開された状態において、互いに直交する長手方向L、幅方向W及び厚さ方向Tを有する。図1に描かれた生理用ナプキン1又は個包装体Pでは、図の上側を長手方向Lの前側(前方)又は腹側とし、図の下側を長手方向Lの後側(後方)又は背側とする。長手方向L及び幅方向Wを含む平面上に置いた生理用ナプキン1又は個包装体Pを厚さ方向Tの上側から見ることを「平面視」といい、平面視で把握される形状を「平面形状」という。長手方向L及び幅方向Wを含む平面内の任意の方向を「平面方向」という。装着者が生理用ナプキン1を装着したとき、厚さ方向Tにて相対的に装着者の肌面に近い側及び遠い側となる側をそれぞれ「肌側」及び「非肌側」という。これら定義は、展開状態の個包装体Pの各資材にも共通に用いられる。
A configuration example of the individual package P of the sanitary napkin 1 according to the present embodiment will be described.
1 to 3 are views showing a configuration example of the individual package P (unfolded state) according to the present embodiment. FIG. 1 is a plan view showing a configuration example of an individual package P (unfolded state) of a sanitary napkin 1. FIG. 2 is a cross-sectional view of the sanitary napkin 1 shown in FIG. 1 along the longitudinal center line CL (described later). FIG. 3 is a bottom view showing the sanitary napkin 1 shown in FIG. The individual wrapping body P includes an individual wrapping sheet 43 and a sanitary napkin 1, and the sanitary napkin 1 is folded and packaged together with the individual wrapping sheet 43 in a state of being placed on the individual wrapping sheet 43. Has a structure. However, as shown in FIG. 1, the individual package P has a longitudinal direction L, a width direction W, and a thickness direction T that are orthogonal to each other in the unfolded state. In the sanitary napkin 1 or the individual package P depicted in FIG. 1, the upper side of the drawing is the front side (front side) or the ventral side of the longitudinal direction L, and the lower side of the figure is the rear side (rear side) or the back side of the longitudinal direction L. Be on the side. Looking at the sanitary napkin 1 or the individual package P placed on a plane including the longitudinal direction L and the width direction W from above in the thickness direction T is called "plan view", and the shape grasped in the plan view is "planar view". It is called "planar shape". Any direction in the plane including the longitudinal direction L and the width direction W is referred to as a "planar direction". When the wearer wears the sanitary napkin 1, the sides relatively close to and far from the skin surface of the wearer in the thickness direction T are referred to as "skin side" and "non-skin side", respectively. These definitions are also commonly used for each material of the individually packaged body P in the unfolded state.

個包装シート43は、長手方向Lの両端部が、生理用ナプキン1の長手方向Lの両端部よりも長手方向Lの外側に長く、かつ幅方向Wの両端部が、生理用ナプキン1の幅方向Wの両端部よりも幅方向Wの外側に長い。すなわち、生理用ナプキン1を個包装シート43上に載置するとき、平面視で、個包装シート43の外側に生理用ナプキン1がはみ出さないようにできる。それにより、生理用ナプキン1が個包装シート43と共に折り畳まれたとき、個包装シート43の外側に生理用ナプキン1がはみ出さず、清潔感を高められる。 In the individual wrapping sheet 43, both ends in the longitudinal direction L are longer than both ends in the longitudinal direction L of the sanitary napkin 1 outside the longitudinal direction L, and both ends in the width direction W are the width of the sanitary napkin 1. It is longer outside the width direction W than both ends of the direction W. That is, when the sanitary napkin 1 is placed on the individual wrapping sheet 43, the sanitary napkin 1 can be prevented from protruding to the outside of the individual wrapping sheet 43 in a plan view. As a result, when the sanitary napkin 1 is folded together with the individual wrapping sheet 43, the sanitary napkin 1 does not protrude from the outside of the individual wrapping sheet 43, and the feeling of cleanliness can be enhanced.

生理用ナプキン1は、主に液体の***物(例示:経血)を吸収する吸収本体3と、吸収本体3の長手方向Lの前側に位置し、肌に温感を知覚させる温感本体(機能本体)5と、を備える。すなわち、生理用ナプキン1は、長手方向Lの後方の吸収本体3と、長手方向Lの前方の温感本体5と、に区画される。吸収本体3の形状は、概ね一般的な生理用ナプキンの形状であり、幅方向Wの両外側に延出する一対のウイング部17、17を備えている。温感本体5の形状は特に限定はなく、例えば、三角形や矩形や多角形(角が丸い場合や辺が曲線の場合を含む)、円形や楕円形、生物の形状、又はそれらの組み合わせが挙げられる。本実施形態では、身体のより広い範囲を温める観点から、温感本体5は、吸収本体3における(一対のウイング部17、17を除いた領域の)幅方向Wの最大幅よりも大きい幅方向Wの寸法を有する。よって、温感本体5は幅広な本体(幅広本体)といえる。 The sanitary napkin 1 is located on the absorption main body 3 that mainly absorbs liquid excrement (example: menstrual blood) and on the front side of the absorption main body 3 in the longitudinal direction L, and makes the skin perceive a warm feeling (exemplary). (Function body) 5 and. That is, the sanitary napkin 1 is divided into an absorption main body 3 at the rear in the longitudinal direction L and a warmth main body 5 at the front in the longitudinal direction L. The shape of the absorption body 3 is generally the shape of a general sanitary napkin, and includes a pair of wing portions 17 and 17 extending to both outer sides in the width direction W. The shape of the warmth body 5 is not particularly limited, and examples thereof include a triangle, a rectangle, a polygon (including a case where the corners are round and a case where the sides are curved), a circle, an ellipse, a shape of a living thing, or a combination thereof. Be done. In the present embodiment, from the viewpoint of warming a wider area of the body, the warmth main body 5 has a width direction larger than the maximum width of the width direction W (in the region excluding the pair of wing portions 17, 17) in the absorption main body 3. It has a dimension of W. Therefore, it can be said that the warm feeling main body 5 is a wide main body (wide main body).

生理用ナプキン1は、幅方向Wの中心を通り長手方向Lに延びる長手方向中心線CL(仮想線)と、一対のウイング部17、17の各々の長手方向Lの中心を幅方向Wに結んだ(長手方向Lの中心を通り幅方向Wに延びる)幅方向中心線CW(仮想線)と、を有する。生理用ナプキン1において、長手方向中心線CLに向かう向き及び側をそれぞれ幅方向Wの内向き及び内側とし、遠ざかる向き及び側をそれぞれ幅方向Wの外向き及び外側とする。一方、幅方向中心線CWに向かう向き及び側をそれぞれ長手方向Lの内向き及び内側とし、遠ざかる向き及び側をそれぞれ長手方向Lの外向き及び外側とする。なお、一対のウイング部17、17の各々が存在しない場合、幅方向中心線CWは、長手方向Lにおいて、吸収本体3における***口当接域21(後述)の中心を通り幅方向Wに延びる線とする。本実施形態では、それらは一致するものとする。あるいは、吸収体11(後述)がいわゆる砂時計型の場合、幅方向中心線CWは、長手方向Lにおいて、吸収体11の幅方向Wの寸法が最小となる位置(両端部を除く)を通り幅方向Wに延びる線とする。 In the sanitary napkin 1, the longitudinal center line CL (virtual line) extending in the longitudinal direction L through the center of the width direction W and the center of each of the pair of wing portions 17 and 17 in the longitudinal direction L are connected in the width direction W. However, it has a width direction center line CW (virtual line) that passes through the center of the longitudinal direction L and extends in the width direction W. In the sanitary napkin 1, the direction and the side toward the center line CL in the longitudinal direction are the inward and the inside of the width direction W, respectively, and the direction and the side away from it are the outward and the outside of the width direction W, respectively. On the other hand, the directions and sides toward the center line CW in the width direction are defined as inward and inside of the longitudinal direction L, respectively, and the directions and sides toward the distance L are defined as outward and outward in the longitudinal direction L, respectively. When each of the pair of wing portions 17 and 17 does not exist, the width direction center line CW extends in the width direction W through the center of the excretion port contact area 21 (described later) in the absorption body 3 in the longitudinal direction L. Let it be a line. In this embodiment, they shall match.

Each leak-proof wall 7W has an outer edge as a fixed end and an inner edge as a free end in the width direction W, and extends above the thickness direction T of the surface sheet 7a. The free ends of the pair of leak-proof walls 7W and 7W can stand up to the skin side when the sanitary napkin 1 is attached. In another embodiment, the liquid permeable sheet 7 does not have a pair of side sheets 7b, 7b. In yet another embodiment, the liquid permeable sheet 7 does not have a pair of leak-proof walls 7W, 7W. In yet another embodiment, the sanitary napkin 1 comprises a liquid diffusion sheet 41 that is in contact with the non-skin side of the surface sheet 7a and diffuses excrement in the plane direction.

吸収体11は、吸収コア(図示されず)及び、吸収コアを包み込むコアラップ(図示されず)を備えている。吸収体11は、コアラップの肌側の表面から吸収コアの内部へ向かって圧搾することで形成された複数の吸収体圧搾部(図示されず)を有する。それら複数の吸収体圧搾部は、吸収体11の型崩れを抑制する。別の実施形態では、吸収体11はコアラップを用いない。更に別の実施形態では、吸収体11は吸収体圧搾部を有さない。 The absorber 11 includes an absorption core (not shown) and a core wrap (not shown) that wraps the absorption core. The absorber 11 has a plurality of absorber squeezing portions (not shown) formed by squeezing from the skin-side surface of the core wrap toward the inside of the absorbing core. The plurality of absorber pressing portions suppress the shape loss of the absorber 11. In another embodiment, the absorber 11 does not use a core wrap. In yet another embodiment, the absorber 11 does not have an absorber squeezed portion.

温感剤保持シート13(機能層)は、液体を保持可能な布帛や不織布のような一層又は複数層のシートから構成されており、温感剤50(機能剤)を含んでいる。温感剤保持シート13の形状は、温感剤50の漏れを抑制する、生理用ナプキン1の周縁部27の内側に配置できれば、特に限定はなく、例えば温感本体5の形状を相似的に縮小した形状が挙げられる。本実施形態では、身体のより広い範囲を温める観点から、温感剤保持シート13は、吸収本体3における一対のウイング部17、17を除いた領域の幅方向Wの最大幅よりも大きい幅方向Wの寸法を有する。温感剤50は、生理用ナプキン1の装着者の身体又はその近傍を加熱等することなく、皮膚の温度受容器(温熱知覚受容器)を刺激し、装着者に温感を知覚させる温感成分を含み、温感成分を溶解ないし分散し得る溶媒成分を更に含む。温感剤50は、気体や液体の形態で、温度、気圧、外力などの影響により、配置された場所から移動し得る流体成分又は揮発成分を含み、例えば温感成分及び溶媒成分の少なくとも一方が流体成分又は揮発成分を含む。温感剤保持シート13が液透過性シート7よりも非肌側に配置されていても、温感剤保持シート13の温感剤50が、生理用ナプキン1の着用時において例えば溶出又は揮発等により液透過性シート7を透過し、装着者の下腹部の肌に接触することができる。それにより、温感剤50の温感成分が皮膚の温熱知覚受容器を刺激し、装着者の下腹部に温感を付与することができる。 The warming agent holding sheet 13 (functional layer) is composed of a single layer or a plurality of layers of sheets such as a cloth or a non-woven fabric capable of holding a liquid, and contains the warming agent 50 (functional agent). The shape of the warming agent holding sheet 13 is not particularly limited as long as it can be arranged inside the peripheral edge portion 27 of the sanitary napkin 1 that suppresses leakage of the warming agent 50. For example, the shape of the warming agent main body 5 is similar. A reduced shape can be mentioned. In the present embodiment, from the viewpoint of warming a wider area of the body, the warming agent holding sheet 13 has a width direction larger than the maximum width of the width direction W of the region of the absorption main body 3 excluding the pair of wing portions 17, 17. It has a dimension of W. The warming agent 50 stimulates the temperature receptor (heat sensory receptor) of the skin without heating the body or the vicinity of the wearer of the sanitary napkin 1, and causes the wearer to perceive the warmth. It contains a component and further contains a solvent component capable of dissolving or dispersing a warming component. The warming agent 50 contains a fluid component or a volatile component that can move from the arranged place due to the influence of temperature, atmospheric pressure, external force, etc. in the form of a gas or a liquid, and for example, at least one of the warming component and the solvent component is contained. Contains fluid or volatile components. Even if the warming agent holding sheet 13 is arranged on the non-skin side of the liquid permeable sheet 7, the warming agent 50 of the warming agent holding sheet 13 elutes or volatilizes, for example, when the sanitary napkin 1 is worn. Allows the liquid-permeable sheet 7 to permeate and come into contact with the skin of the wearer's lower abdomen. Thereby, the warming component of the warming agent 50 stimulates the thermal sensory receptor of the skin, and can give a warm feeling to the lower abdomen of the wearer.

温感剤50は、平面視で温感剤保持シート13における周縁部を含む全体に配置される。それにより、温感剤50の効果が、吸収体11よりも幅方向Wに広い領域に及ぶようになっている。なお、別の実施形態では、温感剤50は、平面視で温感剤保持シート13の幅方向Wの両端部を除く中央部25に配置される。更に別の実施形態では、温感剤50は、温感剤保持シート13の所定の部分、例えば表面シート7aの幅方向Wの範囲で、長手方向Lに延び、幅方向Wに並んだ複数のストライプ状の部分に配置される。更に別の実施形態では、温感剤50は溶媒成分を含まない。更に別の実施形態では、温感本体5は、温感剤保持シート13の非肌側に温感剤保持シート13を支持する支持シートを有する。 The warming agent 50 is arranged on the entire surface including the peripheral portion of the warming agent holding sheet 13 in a plan view. As a result, the effect of the warming agent 50 extends over a wider area in the width direction W than the absorber 11. In another embodiment, the warming agent 50 is arranged in the central portion 25 excluding both ends in the width direction W of the warming agent holding sheet 13 in a plan view. In yet another embodiment, the warming agent 50 extends in the longitudinal direction L in a predetermined portion of the warming agent holding sheet 13, for example, in the width direction W of the surface sheet 7a, and is arranged in the width direction W. It is arranged in a striped part. In yet another embodiment, the warming agent 50 does not contain a solvent component. In yet another embodiment, the warming body 5 has a support sheet that supports the warming agent holding sheet 13 on the non-skin side of the warming agent holding sheet 13.

なお、別の実施形態として、生理用ナプキン1に付与する所定の機能を冷感機能とする場合、冷感剤保持シートは冷感剤(機能剤)を含み、冷感剤は冷感成分と溶媒成分とを含む。更に別の実施形態として、生理用ナプキン1に付与する所定の機能を保温機能とする場合、保温性シートは、機能剤を含まず、例えば保温性の高い不織布や布帛を含む。 As another embodiment, when a predetermined function imparted to the sanitary napkin 1 is a cooling sensitizing function, the cooling sensitizer holding sheet contains a cooling sensitizer (functional agent), and the cooling sensitizer is a cooling sensitizer component. Contains solvent components. As yet another embodiment, when the predetermined function imparted to the sanitary napkin 1 is a heat retaining function, the heat retaining sheet does not contain a functional agent, and includes, for example, a non-woven fabric or cloth having high heat retaining property.

温感剤保持シート13は、液体を保持可能なシート(例示:不織布)から構成されているので、吸収体11ほどではないが、***物を吸収できる。したがって、温感剤保持シート13は、吸収体11よりも低い吸収性能を有する低吸収部と見ることができる。低吸収部は、温感本体5に属しているが、長手方向Lの前方での***物の吸収を補助できる。 Since the warming agent holding sheet 13 is composed of a sheet capable of holding a liquid (example: non-woven fabric), it can absorb excrement, though not as much as the absorber 11. Therefore, the warming agent holding sheet 13 can be regarded as a low absorption portion having a lower absorption performance than the absorber 11. Although the low absorption portion belongs to the warm feeling main body 5, it can assist the absorption of excrement in the front in the longitudinal direction L.

個包装体Pは、吸収本体3及び温感本体5の両方において、液不透過性シート9の非肌側の面に、生理用ナプキン1を装着者の着衣に固定するための粘着部71〜73と、粘着部71〜73を仮固定するための剥離シート81〜83と、剥離シート81〜83を個包装シート43に固定するための粘着部91〜93と、を備えている。粘着部71は、ウイング部17の幅方向Wの略中央部に配置される。粘着部72は、温感本体5の幅方向Wの両端部の各々の領域に配置される。粘着部73は、平面視で、吸収体11と重なる領域に配置される。それらにより、液不透過性シート9の非肌側の面(個包装シート43側の面)は、剥離シート81〜83の肌側の面(個包装シート43と反対側の面)に、粘着部71〜73を介して仮固定される。剥離シート81〜83の非肌側の面は、個包装シート43の肌側の面に、粘着部91〜93を介して固定されている。別の実施形態では、剥離シート81〜83及び粘着部91〜93は存在せず、液不透過性シート9の非肌側の面(個包装シート43側の面)は、個包装シート43の肌側の面に、粘着部71〜73を介して仮固定される。更に別の実施形態では、更に、粘着部71〜73も存在しない。 The individual package P is an adhesive portion 71 to 71 for fixing the sanitary napkin 1 to the wearer's clothes on the non-skin side surface of the liquid impermeable sheet 9 in both the absorption body 3 and the warmth body 5. 73, release sheets 81 to 83 for temporarily fixing the adhesive portions 71 to 73, and adhesive portions 91 to 93 for fixing the release sheets 81 to 83 to the individual wrapping sheet 43 are provided. The adhesive portion 71 is arranged at a substantially central portion of the wing portion 17 in the width direction W. The adhesive portions 72 are arranged in the respective regions of both ends of the warm feeling main body 5 in the width direction W. The adhesive portion 73 is arranged in a region overlapping the absorber 11 in a plan view. As a result, the non-skin side surface of the liquid impermeable sheet 9 (the surface on the individual wrapping sheet 43 side) adheres to the skin side surface (the surface opposite to the individual wrapping sheet 43) of the release sheets 81 to 83. It is temporarily fixed via the portions 71 to 73. The non-skin side surface of the release sheets 81 to 83 is fixed to the skin side surface of the individual wrapping sheet 43 via the adhesive portions 91 to 93. In another embodiment, the release sheets 81 to 83 and the adhesive portions 91 to 93 are not present, and the non-skin side surface (individual wrapping sheet 43 side surface) of the liquid impermeable sheet 9 is the individual wrapping sheet 43. It is temporarily fixed to the surface on the skin side via the adhesive portions 71 to 73. In yet another embodiment, the adhesive portions 71-73 are also absent.

本実施形態では、粘着部72は、平面視で、幅方向Wにおいて、温感剤保持シート13の両端部の各々の領域であって、表面シート7aよりも外側の領域に形成される。その領域は、平面視で、幅方向Wにおいて、温感剤保持シート13における最も外側の両端縁から、温感剤保持シート13の最大寸法の30%の距離だけ内側の位置までの領域である。温感剤保持シート13及び粘着部72は、厚さ方向Tにおいて、互いに重複する。なお、別の実施形態では、温感剤保持シート13及び粘着部72は、厚さ方向Tにおいて、互いに一部分だけ重複するか、又は互いに全く重複しない位置に配置される。温感剤50が粘着部72に達して、粘着部72を劣化させるのを抑制するためである。 In the present embodiment, the adhesive portion 72 is formed in each region of both end portions of the warming agent holding sheet 13 in the width direction W in a plan view, and is formed in a region outside the surface sheet 7a. The region is a region in the width direction W from the outermost both end edges of the sensitizer holding sheet 13 to a position inside by a distance of 30% of the maximum dimension of the sensitizer holding sheet 13 in a plan view. .. The warming agent holding sheet 13 and the adhesive portion 72 overlap each other in the thickness direction T. In another embodiment, the warming agent holding sheet 13 and the adhesive portion 72 are arranged at positions where they partially overlap each other or do not overlap each other at all in the thickness direction T. This is to prevent the warming agent 50 from reaching the adhesive portion 72 and deteriorating the adhesive portion 72.

個包装体Pは、長手方向Lにおいて、第1幅方向折線F及び第2幅方向折線Fにより三つの領域に区画される。すなわち、個包装体Pは、長手方向Lに、第1幅方向折線Fよりも外側(一端側)の第1長手方向折り畳み部Aと、第2幅方向折線Fよりも外側(他端側)の第2長手方向折り畳み部Aと、第1幅方向折線Fと第2幅方向折線Fとの間の長手方向中央部Aと、に区画される。なお、それらの部分は、個包装体Pが第1幅方向折線F及び第2幅方向折線Fで折り畳まれた場合でも、同様に第1長手方向折り畳み部A、第2長手方向折り畳み部A及び長手方向中央部Aと称される。Individual package P, in the longitudinal direction L, is divided into three areas by the first widthwise fold lines F 3 and the second widthwise fold line F 4. That is, the individual packaging body P is in the longitudinal direction L, the first longitudinal folds A 1 of the outer side (one end side) than the first width direction fold line F 3, the outer (other than the second width direction fold line F 4 a second longitudinal folding unit a 2 end side), and the longitudinal center a C between the first widthwise fold lines F 3 and the second widthwise fold line F 4, it is divided into. Incidentally, those portions, even if the individual package P is folded by the first widthwise fold lines F 3 and the second widthwise fold line F 4, likewise the first longitudinal folds A 1, folded second longitudinal referred to as part a 2 and longitudinal center portion a C.

FIG. 4 is a configuration of the individual package P (individual package state) of the sanitary napkin 1. It is a perspective view which shows an example. FIG. 5 is a plan view showing a configuration example of the individual package P of the sanitary napkin 1. FIG. 6 is a schematic view showing an individual packaging method (method of forming an individual package P) of the sanitary napkin 1 according to the embodiment. In the individually packaged body P, as shown in FIG. 4, it is assumed that the longitudinal direction L, the width direction W, and the thickness direction T, which are orthogonal to each other, are used even in the individually packaged state. However, the longitudinal direction L, the width direction W, and the thickness direction T of the individually packaged individual packages P of FIGS. 4 to 6 are the lengths of the individually packaged bodies P of FIGS. 1 to 3 in the unfolded state. The orientation may be different from the direction L, the width direction W, and the thickness direction T.

個包装体Pは、図6に示すように、生理用ナプキン1が、個包装シート43上に載置された状態で、個包装シート43と共に折り畳まれて形成される。具体的には、個包装体Pの形成方法、すなわち生理用ナプキン1の個包装方法は、まず、図6(a)に示すように、生理用ナプキン1が個包装シート43上に載置される。次いで、図6(b)に示すように、第2幅方向折り畳み部Bが、第2長手方向折線Fを基点として、幅方向Wの内側に、よって幅方向中央部B上に折り畳まれる。それと共に、第1幅方向折り畳み部Bが、第1長手方向折線Fを基点として、幅方向Wの内側に、よって幅方向中央部B上に折り畳まれる。次いで、図6(c)に示すように、第2長手方向折り畳み部Aが、第2幅方向折線Fを基点として、長手方向Lの内側に、よって長手方向中央部A上に折り畳まれる。次いで、図6(d)に示すように、第1長手方向折り畳み部Aが、第1幅方向折線Fを基点として、長手方向Lの内側に、よって長手方向中央部A上に折り畳まれる。ここで、第1長手方向折り畳み部Aにおける第1幅方向折線Fの側の第1端部E11とは長手方向Lの反対側に位置する第2端部E12の表面Sには、粘着テープ45の一端部が接合されている。そして、粘着テープ45の他端部が、第2長手方向折り畳み部Aの表面Sに接合される。それにより、図4に示すような、生理用ナプキン1の個包装体Pが形成される。なお、生理用ナプキン1が使用されるときには、すなわち個包装体Pが開封されるときには、上記された個包装方法とは逆の手順で開封される。As shown in FIG. 6, the individual packaging body P is formed by folding the sanitary napkin 1 together with the individual packaging sheet 43 in a state where the sanitary napkin 1 is placed on the individual packaging sheet 43. Specifically, in the method of forming the individual packaging body P, that is, the individual packaging method of the sanitary napkin 1, first, as shown in FIG. 6A, the sanitary napkin 1 is placed on the individual packaging sheet 43. To. Then, as shown in FIG. 6 (b), the second width direction folds B 2, the second longitudinal fold line F 2 as a base point, on the inner side in the width direction W, thus folded widthwise central portion on B C Is done. At the same time, the folding portion B 1 first width direction, the first longitudinal fold line F 1 as a base point, on the inner side in the width direction W, thus folded in the widthwise central portion on B C. Then, as shown in FIG. 6 (c), the second is the longitudinal folds A 2, the second widthwise fold line F 4 as a reference point, on the inner side of the longitudinal direction L, thus folded longitudinally central portion on A C Is done. Then, as shown in FIG. 6 (d), the first longitudinal folds A 1 is a first widthwise fold line F 3 as a base point, on the inner side of the longitudinal direction L, thus folded longitudinally central portion on A C Is done. Here, the surface S 1 of the second end E 12 and the first end E 11 of the first widthwise fold line F 3 side of the first longitudinal folds A 1 located on the opposite side of the longitudinal direction L Is joined to one end of the adhesive tape 45. The other end portion of the adhesive tape 45 is bonded to the surface S 2 of the second longitudinal folding unit A 2. As a result, the individual package P of the sanitary napkin 1 as shown in FIG. 4 is formed. When the sanitary napkin 1 is used, that is, when the individual package P is opened, the package is opened in the reverse procedure of the individual packaging method described above.

個包装体Pでは、個包装された状態において、図4に示すように、第1長手方向折り畳み部Aが、一対の側部63、63と、中間部61と、を含んでいる。ここで、一対の側部63、63は、第1長手方向折線Fと第2長手方向折線Fとで折り畳まれた第1長手方向折り畳み部Aにおける粘着テープ45の幅方向Wの両側に位置しており、長手方向Lに延在している。本実施形態では、一方の側部63は、第1長手方向折り畳み部Aにおいて、粘着テープ45の幅方向Wの一方の側縁の位置を、側部63の幅方向Wの一方の端縁として、その端縁よりも幅方向Wの外側の部分である。他方の側部63は、粘着テープ45の幅方向Wの他方の側縁を、側部63の幅方向Wの一方の端縁として、その端縁よりも幅方向Wの外側の部分である。別の実施形態では、一対の側部63、63の各々における幅方向Wの内側の端縁は、粘着テープ45の幅方向Wの両端縁よりも、内側又は外側のいずれかである。ただし、内側又は外側は、幅方向Wにおいて、例えば、粘着テープ45の幅方向Wの端縁から粘着テープ45の幅方向Wの寸法の1/2未満の範囲である。In the individual package P, in individually packaged state, as shown in FIG. 4, a first longitudinal folds A 1 is includes a pair of side portions 63, 63, an intermediate portion 61, a. Here, a pair of side portions 63, 63 on both sides in the width direction W of the first longitudinal fold lines F 1 and the second longitudinal fold line F 2 and the adhesive tape 45 in the first longitudinal folds A 1 folded in It is located in and extends in the longitudinal direction L. In the present embodiment, one side portion 63 positions the position of one side edge of the adhesive tape 45 in the width direction W in the first longitudinal folding portion A1 and one end edge of the width direction W of the side portion 63. As a result, it is a portion outside the width direction W from the edge. The other side portion 63 is a portion outside the width direction W with respect to the other side edge of the adhesive tape 45 in the width direction W as one end edge of the width direction W of the side portion 63. In another embodiment, the inner edges of the pair of side portions 63, 63 in the width direction W are either inside or outside the edges of the adhesive tape 45 in the width direction W. However, the inside or the outside is a range in the width direction W, for example, from the edge of the width direction W of the adhesive tape 45 to less than 1/2 of the dimension of the width direction W of the adhesive tape 45.

中間部61は、幅方向Wにおいて、一対の側部63、63の間に位置しており、長手方向Lに延在している。中間部61は、幅方向Wにおいて、粘着テープ45の寸法と同じ寸法を有し、一対の側部63、63の両方に接している。別の実施形態では、中間部61は、幅方向Wにおいて、粘着テープ45の寸法未満の寸法を有し、一対の側部63、63の間に位置し、一対の側部63、63の一方に接している。更に、別の実施形態では、中間部61は、幅方向Wにおいて、粘着テープ45の寸法未満の寸法を有し、一対の側部63、63の間に位置し、一対の側部63、63の両方に接していない。 The intermediate portion 61 is located between the pair of side portions 63, 63 in the width direction W, and extends in the longitudinal direction L. The intermediate portion 61 has the same dimensions as the adhesive tape 45 in the width direction W, and is in contact with both of the pair of side portions 63, 63. In another embodiment, the intermediate portion 61 has a dimension less than the dimension of the adhesive tape 45 in the width direction W, is located between the pair of side portions 63, 63, and is one of the pair of side portions 63, 63. Is in contact with. Further, in another embodiment, the intermediate portion 61 has a dimension less than the dimension of the adhesive tape 45 in the width direction W, is located between the pair of side portions 63, 63, and is located between the pair of side portions 63, 63. Not in contact with both.

本実施形態では、一対の側部63、63の各々の剛性は、中間部61の剛性よりも高い。言い換えれば、中間部61は、一対の側部63、63の間の領域のうちの、相対的に剛性が低い領域ということができる。それゆえ、幅方向Wの両外側から個包装体P(の第1長手方向折り畳み部A)に力が加わると、各側部63は変形し難く、中間部61は変形し易い。したがって、上記の幅方向Wの力を、一対の側部63、63を相対的に小さく変形させつつ、中間部61を相対的に大きく変形させて逃がすことができる。なお、中間部61は、一対の側部63、63の間の領域に相対的に剛性が低い領域として存在すればよいので、幅方向Wの全域に亘って存在する必要はなく、幅方向Wの一部の領域に存在していればよい。In the present embodiment, the rigidity of each of the pair of side portions 63, 63 is higher than the rigidity of the intermediate portion 61. In other words, the intermediate portion 61 can be said to be a region having relatively low rigidity in the regions between the pair of side portions 63, 63. Therefore, when a force is applied from both sides in the width direction W in individual package P (first longitudinal folds A 1) of each side portion 63 is hardly deformed, intermediate section 61 is deformed easily. Therefore, the force in the width direction W can be released by deforming the pair of side portions 63, 63 relatively small and the intermediate portion 61 relatively large. Since the intermediate portion 61 may exist as a region having relatively low rigidity in the region between the pair of side portions 63, 63, it does not have to exist over the entire width direction W, and the intermediate portion 61 does not need to exist over the entire width direction W. It suffices if it exists in a part of the area of.

本実施形態では、一方の側部63には、第1幅方向折り畳み部B及び幅方向中央部Bの幅方向Wの一方側の部分が厚さ方向Tに積層され、他方の側部63には、第2幅方向折り畳み部B及び幅方向中央部Bの幅方向Wの他方側の部分が厚さ方向Tに積層されている。したがって、図5などに示すように、各側部63の大部分は、粘着部72と、剥離シート82と、粘着部92と、2枚分の温感剤保持シート13と、2枚分の液透過性シート7と、2枚分の液不透過性シート9と、2枚分の個包装シート43と、が厚さ方向Tに積層されている。一方、中間部61は、幅方向中央部B並びに第1幅方向折り畳み部B及び第2幅方向折り畳み部Bの幅方向Wの外側の端縁の近傍部分が厚さ方向Tに積層されている。したがって、図5などに示すように、中間部61の大部分は、温感剤保持シート13と、2枚分の液透過性シート7と、2枚分の液不透過性シート9と、3枚分の個包装シート43と、が厚さ方向Tに積層されている。ここで、側部63及び中間部61における液透過性シート7、液不透過性シート9、個包装シート43の剛性に対する効果を同程度と考えると、各側部63は、中間部61と比較して、粘着部72、剥離シート82、粘着部92、及び温感剤保持シート13をより多く含んでいる。よって、各側部63は、中間部61よりも多くの層で形成されている。言い換えれば、中間部61は、一対の側部63、63の間の領域における、相対的に少ない層で形成された領域ということができる。それゆえ、幅方向Wの両外側から個包装体P(の第1長手方向折り畳み部A)に力が加わったとき、各側部63は変形し難く、中間部61は変形し易い。したがって、上記の幅方向Wの力を、一対の側部63、63を相対的に小さく変形させつつ、中間部61を相対的に大きく変形させて逃がすことができる。なお、中間部61としては、一対の側部63、63の間の領域に相対的に少ない層で形成された領域として存在すればよいので、幅方向Wの全域に亘って存在する必要はなく、幅方向Wの一部の領域に存在していればよい。In this embodiment, the one side 63, one side portion of the width direction W of the first widthwise fold B 1 and the width direction central portion B C are stacked in the thickness direction T, the other side In 63, the other side of the second width direction folding portion B 2 and the width direction central portion BC in the width direction W is laminated in the thickness direction T. Therefore, as shown in FIG. 5 and the like, most of the side portions 63 are the adhesive portion 72, the release sheet 82, the adhesive portion 92, the warming agent holding sheet 13 for two sheets, and two sheets. A liquid-permeable sheet 7, two liquid-impermeable sheets 9, and two individually wrapped sheets 43 are laminated in the thickness direction T. On the other hand, in the intermediate portion 61, a portion near the outer edge of the width direction central portion BC , the first width direction folding portion B 1 and the second width direction folding portion B 2 in the width direction W is laminated in the thickness direction T. Has been done. Therefore, as shown in FIG. 5 and the like, most of the intermediate portion 61 is a warming agent holding sheet 13, two liquid permeable sheets 7, two liquid permeable sheets 9, and three. The individual wrapping sheets 43 for each sheet are laminated in the thickness direction T. Here, considering that the effects of the liquid permeable sheet 7, the liquid impermeable sheet 9, and the individually wrapped sheet 43 on the rigidity of the side portion 63 and the intermediate portion 61 are about the same, each side portion 63 is compared with the intermediate portion 61. As a result, the adhesive portion 72, the release sheet 82, the adhesive portion 92, and the warming agent holding sheet 13 are contained in a larger amount. Therefore, each side portion 63 is formed of more layers than the intermediate portion 61. In other words, the intermediate portion 61 can be said to be a region formed by a relatively small number of layers in the region between the pair of side portions 63, 63. Therefore, when a force is applied on both outer sides from the individual package P (first longitudinal folds A 1) of the width direction W, each side portion 63 is hard to deform, the intermediate portion 61 is deformed easily. Therefore, the force in the width direction W can be released by deforming the pair of side portions 63, 63 relatively small and the intermediate portion 61 relatively large. Since the intermediate portion 61 may exist as a region formed by a relatively small number of layers in the region between the pair of side portions 63, 63, it does not have to exist over the entire width direction W. , It suffices if it exists in a part of the area in the width direction W.

次に、実施形態に係る生理用ナプキン1の個包装体Pの作用を説明する。図7は、個包装体Pの作用を示す模式図である。使用者が一方の手Hで個包装体Pを幅方向Wに把持することで、個包装体Pに、その幅方向Wの両端部から中央部に向かう力Kが加わる場合がある。その場合、加わった力Kの大きさが強過ぎるときには、個包装体P、したがって第1長手方向折り畳み部A及び第2長手方向折り畳み部Aのいずれも手のひらの形状に沿って、略凹状に変形してしまう状況が生じ得る。そうなると、粘着テープ45を上手に摘まむことが困難になるおそれがある。Next, the action of the individual package P of the sanitary napkin 1 according to the embodiment will be described. FIG. 7 is a schematic view showing the action of the individual package P. When the user grips the individual package P in the width direction W with one hand H, a force K from both ends of the width direction W to the center may be applied to the individual package P. In that case, when there is too strong magnitude of applied force K is the individual package P, thus none of the first longitudinal folds A 1 and the second longitudinal folding unit A 2 along the shape of the palm, generally concave There may be a situation where it is transformed into. In that case, it may be difficult to pinch the adhesive tape 45 well.

そこで、本生理用ナプキン1では、第1長手方向折り畳み部Aにおいて、粘着テープ45の両側に位置する一対の側部63、63の各々の剛性を、一対の側部63、63の間に位置する中間部61の剛性よりも高くしている。したがって、第1長手方向折り畳み部Aに幅方向Wの両端部から中央部に向かう力Kが加わったとき、剛性の高い各側部63を変形し難くすることができ、剛性の低い中間部61を変形し易くすることができる。
あるいは、本生理用ナプキン1では、第1長手方向折り畳み部Aにおいて、一対の側部63、63の各々の内部に補強部材(例示:温感剤保持シート13、粘着部72、剥離シート82、粘着部92や、他のシート部材)を配置している。したがって、第1長手方向折り畳み部Aに幅方向Wの両端部から中央部に向かう力Kが加わったとき、補強部材を含む各側部を変形し難くすることができ、補強部材を含まない中間部が変形し易くすることができる。
Accordingly, the present sanitary napkin 1, the first longitudinal folds A 1, each of the rigidity of the pair of side portions 63, 63 positioned on both sides of the adhesive tape 45, between a pair of side portions 63, 63 It is made higher than the rigidity of the intermediate portion 61 located. Therefore, when a force is applied K toward the central portion from both ends of the first longitudinal folds A 1 in the width direction W, it is possible to make it difficult to deform the stiff each side 63, a lower rigid intermediate portion The 61 can be easily deformed.
Alternatively, the present sanitary napkin 1, the first longitudinal folds A 1, the reinforcing member (illustrated within each of the pair of side portions 63, 63: warming agents holding sheet 13, the adhesive portion 72, the release sheet 82 , Adhesive portion 92 and other sheet members) are arranged. Therefore, when a force is applied K toward the central portion from both end portions in the width direction W in the first longitudinal folds A 1, can be difficult to deform each side including a reinforcing member does not include a reinforcement member The intermediate portion can be easily deformed.

ただし、中間部61は粘着テープ45で第2長手方向折り畳み部Aに固定されてやや変形し難い。そのため、第1長手方向折り畳み部Aに幅方向Wの両端部から中央部に向かう力Kが加わったとき、一対の側部63、63と中間部61との境界付近の部分が主に変形することになる。具体的には、長手方向Lから見て、第1長手方向折り畳み部Aのうち、一対の側部63、63と中間部61との境界付近の部分が変形することで、中間部61を基点として、一対の側部63、63における、個包装体Pの幅方向Wの両端部に対応する部分が立ち上がる。すなわち、中間部61を一種の折線(又は基点)として、その両側の側部63、63が立ち上がり、略V字の形状が形成される。このとき、第2長手方向折り畳み部Aは略凹状に変形するが、その幅方向Wの外側の部分の立ち上がりは少ない。そのため、第2長手方向折り畳み部Aと一対の側部63、63の各々との間に隙間Vが生じる。これらの隙間Vが生じると、使用者は、自然に、いずれかの隙間Vに指を挿入して、その側部63を摘まんで、第2長手方向折り畳み部Aから引き離すことで、粘着テープ45を剥離しようとする。ここで、一対の側部63、63の各々は、相対的に剛性が高いので、その引き離そうとする力を粘着テープ45に容易に伝達することができる。それにより、使用者は、隙間Vに指を挿入して、側部63を摘まんで、粘着テープ45を剥離させて、容易に、個包装体Pを開封することが可能となる。すなわち、生理用ナプキン1の個包装体Pにおいて、一方の手Hで把持して、他方の手で開封する際にも、開封し易い個包装体Pを提供できる。However, hardly the intermediate portion 61 is slightly deformed is fixed to the second longitudinal folding unit A 2 with the adhesive tape 45. Therefore, when a force K is applied toward the center portion from both ends of the first longitudinal folds A 1 in the width direction W, the portion in the vicinity of the boundary between the pair of side 63 and the intermediate portion 61 is mainly deformed Will be done. Specifically, when viewed from the longitudinal direction L, of the first longitudinal folds A 1, that portion of the vicinity of the boundary between the pair of side 63 and the intermediate portion 61 is deformed, the intermediate portion 61 As a base point, portions of the pair of side portions 63, 63 corresponding to both ends of the individual package P in the width direction W stand up. That is, with the intermediate portion 61 as a kind of folding line (or base point), the side portions 63 and 63 on both sides thereof rise to form a substantially V-shaped shape. At this time, the second longitudinal folding portion A 2 is deformed in a substantially concave shape, but the rising portion of the outer portion in the width direction W is small. Therefore, the gap V is generated between the respective second longitudinal folding unit A 2 and the pair of side 63, 63. When these gaps V occurs, the user naturally by inserting a finger into one of the gaps V, in does picked the side portion 63, by pulling apart the second longitudinal folding unit A 2, the adhesive tape Attempts to peel off 45. Here, since each of the pair of side portions 63, 63 has relatively high rigidity, the force for pulling them apart can be easily transmitted to the adhesive tape 45. As a result, the user can easily open the individual package P by inserting a finger into the gap V, pinching the side portion 63, and peeling off the adhesive tape 45. That is, in the individual package P of the sanitary napkin 1, it is possible to provide the individual package P that is easy to open even when the individual package P is gripped by one hand H and opened by the other hand.

ここで、側部63は相対的に剛性が高い(又は変形し難い)が、側部63全体が、高剛性である必要はなく、部分的に高剛性であればよい。平面視で、側部63における剛性の高い(又は変形し難い)領域の面積は、側部63全体の面積の30%以上が挙げられ、40%以上が好ましく、50%以上がより好ましい、60%以上が更により好ましい。また、平面視において、側部63における剛性が高い(又は変形し難い)領域の長手方向Lの寸法は、力Kを加える指が配置される範囲を考慮して、側部63の長手方向Lの寸法の30%以上が挙げられ、40%以上が好ましく、50%以上がより好ましい、60%以上が更により好ましい。また、平面視において、側部63における剛性が高い(又は変形し難い)領域の幅方向Wの寸法は、力Kに対する抵抗力の観点から、側部63の幅方向Wの寸法の60%以上が挙げられ、70%以上が好ましく、80%以上がより好ましい、90%以上が更により好ましい。 Here, the side portion 63 has relatively high rigidity (or is hard to be deformed), but the entire side portion 63 does not have to have high rigidity, and may be partially high rigidity. In a plan view, the area of the highly rigid (or hard to deform) region of the side portion 63 is 30% or more of the total area of the side portion 63, preferably 40% or more, more preferably 50% or more, 60. % Or more is even more preferable. Further, in a plan view, the dimension of the region 63 having high rigidity (or being hard to be deformed) in the longitudinal direction is determined in the longitudinal direction L of the side 63 in consideration of the range in which the finger for applying the force K is arranged. 30% or more of the dimensions are mentioned, 40% or more is preferable, 50% or more is more preferable, and 60% or more is even more preferable. Further, in a plan view, the dimension of the width direction W of the region having high rigidity (or being hard to be deformed) in the side portion 63 is 60% or more of the dimension of the width direction W of the side portion 63 from the viewpoint of resistance to the force K. 70% or more is preferable, 80% or more is more preferable, and 90% or more is even more preferable.

一方、中間部61は剛性の低い(又は変形し易い)が、一対の側部63、63の間の領域全体が、低剛性である必要はなく、部分的に低剛性であればよい。平面視において、一対の側部63、63の間の領域における剛性の低い(又は変形し易い)領域の面積は、一対の側部63、63の間の領域全体の面積の40%以上が挙げられ、50%以上が好ましく、60%以上がより好ましい、70%以上が更により好ましい。また、平面視において、一対の側部63、63の間の領域における剛性の低い(又は変形し易い)領域の長手方向Lの最大寸法は、中間部61が一種の折線として機能する観点から、側部63の長手方向Lの寸法の60%以上が挙げられ、70%以上が好ましく、80%以上がより好ましい、90%以上が更により好ましい。また、平面視において、一対の側部63、63の間の領域における剛性の低い(又は変形し易い)領域の幅方向Wの最大寸法は、中間部61が一種の折線として機能する観点から、一対の側部63、63の間の領域全体の幅方向Wの寸法の10%以上が挙げられ、20%以上が好ましく、30%以上がより好ましい、40%以上が更により好ましい。 On the other hand, the intermediate portion 61 has low rigidity (or is easily deformed), but the entire region between the pair of side portions 63, 63 does not have to be low rigidity, and may be partially low rigidity. In a plan view, the area of the region having low rigidity (or being easily deformed) in the region between the pair of side portions 63, 63 is 40% or more of the area of the entire region between the pair of side portions 63, 63. 50% or more is preferable, 60% or more is more preferable, and 70% or more is even more preferable. Further, in a plan view, the maximum dimension of the region having low rigidity (or being easily deformed) in the region between the pair of side portions 63, 63 in the longitudinal direction is determined from the viewpoint that the intermediate portion 61 functions as a kind of folding line. 60% or more of the dimension of the side portion 63 in the longitudinal direction L is mentioned, 70% or more is preferable, 80% or more is more preferable, and 90% or more is even more preferable. Further, in a plan view, the maximum dimension of the width direction W of the region having low rigidity (or easily deformed) in the region between the pair of side portions 63, 63 is determined from the viewpoint that the intermediate portion 61 functions as a kind of folding line. 10% or more of the widthwise W dimension of the entire region between the pair of side portions 63, 63 is mentioned, preferably 20% or more, more preferably 30% or more, even more preferably 40% or more.

一対の側部63、63の各々の剛性(又は変形し難さ)を相対的に高める方法としては、上記のように、中間部61が含まない層(例示:粘着部72、剥離シート82、粘着部92)又は含んでも数が少ない層(温感剤保持シート13)を側部63に追加することで、側部63を相対的に多層で形成する方法が挙げられる。このような温感剤保持シート13、粘着部72、剥離シート82及び粘着部92等は、側部63の剛性を補強する補強部材ということができる。あるいは、剛性を相対的に高める方法としては、上記のように、既に含まれているシート部材等の資材を、側部63の剛性が高くなるように、側部63に含まれ、中間部61に含まれないように配置したり、側部63に配置された資材の剛性を高めたりする方法があり得る。資材の剛性を高める方法としては、材質の変更や厚さの変更などの方法があり得る。あるいは、剛性を相対的に高める方法としては、上記の剥離シート以外の、相対的に剛性の高いシート部材などの部材を補強部材として、平面視で、側部63の全体又は一部に挿入する方法があり得る。 As a method of relatively increasing the rigidity (or difficulty of deformation) of each of the pair of side portions 63, 63, as described above, a layer not including the intermediate portion 61 (example: adhesive portion 72, release sheet 82, A method of forming the side portion 63 in a relatively multi-layered manner by adding the adhesive portion 92) or a layer (heat sensitizer holding sheet 13) which is small in number to the side portion 63 can be mentioned. Such a warming agent holding sheet 13, an adhesive portion 72, a release sheet 82, an adhesive portion 92, and the like can be said to be reinforcing members that reinforce the rigidity of the side portion 63. Alternatively, as a method of relatively increasing the rigidity, as described above, the material such as the sheet member already included is included in the side portion 63 so that the rigidity of the side portion 63 is increased, and the intermediate portion 61 is included. There may be a method of arranging the material so as not to be included in the side portion 63 or increasing the rigidity of the material arranged in the side portion 63. As a method of increasing the rigidity of the material, there may be a method such as changing the material or changing the thickness. Alternatively, as a method of relatively increasing the rigidity, a member such as a sheet member having a relatively high rigidity other than the above-mentioned release sheet is inserted as a reinforcing member into the whole or a part of the side portion 63 in a plan view. There can be a way.

ただし、側部63と中間部61との間の剛性(又は変形し難さ)の比較は、以下に説明する押込力の測定結果を比較することにより行うことができる。押込力は、略板状の試料に所定の冶具を厚さ方向に所定距離だけ押し込んだときに要する荷重の大きさとして測定される。押込力が大きいほど変形し難い、よって、剛性が高いといえる。押込力を測定する装置は、試料台と、試料台の上面からの内部へ延びる孔部と、試料台の上面に試料を固定する固定具と、試料台の上方に配置され、孔部へ挿通可能な円柱状の冶具と、冶具に掛かる荷重を測定するデジタルフォースゲージと、を備える。測定方法は、測定対象領域が孔部を覆うように試料を試料台の上面に載置して固定具で固定し、試料の上方から孔部へ向かって冶具を下降させたとき、冶具に掛かる荷重を測定する。その測定方法は、具体的には次のように行う。 However, the rigidity (or difficulty of deformation) between the side portion 63 and the intermediate portion 61 can be compared by comparing the measurement results of the pushing force described below. The pushing force is measured as the magnitude of the load required when a predetermined jig is pushed into a substantially plate-shaped sample by a predetermined distance in the thickness direction. The larger the pushing force, the more difficult it is to deform, so it can be said that the rigidity is high. The device for measuring the pushing force is a sample table, a hole extending inward from the upper surface of the sample table, a fixture for fixing the sample on the upper surface of the sample table, and a fixture placed above the sample table and inserted into the hole. It is equipped with a possible columnar jig and a digital force gauge that measures the load applied to the jig. The measurement method is that the sample is placed on the upper surface of the sample table so that the measurement target area covers the hole, fixed with a fixture, and when the jig is lowered from above the sample toward the hole, the jig is hooked. Measure the load. Specifically, the measurement method is as follows.

(1)第1長手方向折線F及び第2長手方向折線Fで折り畳まれた第1長手方向折り畳み部Aを切り出して試料とする。試料の第1長手方向折り畳み部Aを、例えば、2mm角の矩形を有する複数の測定対象領域で区画しておく。
(2)試料の平面方向(長手方向L及び幅方向W)と、試料台の上面とが平行になるように、試料を試料台の上面に載置して固定具で固定する。ただし、試料台には、試料台の上面から略垂直に内部へ延びる孔部(直径20mm×深さ10mm)が形成されている。試料を、一つの測定対象領域の中心が孔部の中心に位置するように、固定する。
(3)試料台をスタンド上にセットする(試料台がスタント上に予めセットされていてもよい)。ただし、スタンドは、鉛直方向の上方に延びる柱状部材を備える。柱状部材には測定子の先端に円柱状の冶具(直径2mm×長さ100mm)が連結されたデジタルフォースゲージ(FGP−5:日本電産シンポ株式会社製)が取り付けられている。冶具は、試料台の孔部の鉛直方向の上方に、その先端が試料の測定対象領域に接するように配置される。このとき、冶具は、試料の平面方向に対して垂直に移動して、厚さ方向Tに試料を押し込むことが可能になっている。
(4)冶具を、速度30mm/minで鉛直方向の下方に移動させて、試料の測定対象領域を厚さ方向Tに1mm押込む。そのときのデジタルフォースゲージが計測した最大荷重(N)を記録する。
(5)第1長手方向折り畳み部Aにおいて測定対象領域を順次変更して、(1)〜(4)の測定を繰り返し、第1長手方向折り畳み部A全体を測定する。
(6)異なるN個(Nは3以上の自然数)のサンプルで、(1)〜(5)の測定を繰り返し、それらの平均値を、押込力として採用する。
(1) a first cut out longitudinal folds A 1 and sample folded in the first longitudinal fold lines F 1 and a second longitudinal fold line F 2. The first longitudinal folding unit A 1 sample, for example, previously partitioned in a plurality of measurement target region having a rectangular 2mm square.
(2) Place the sample on the upper surface of the sample table and fix it with a fixture so that the plane direction (longitudinal direction L and width direction W) of the sample is parallel to the upper surface of the sample table. However, the sample table is formed with a hole (diameter 20 mm × depth 10 mm) extending inward substantially vertically from the upper surface of the sample table. The sample is fixed so that the center of one measurement target area is located at the center of the hole.
(3) Set the sample table on the stand (the sample table may be preset on the stunt). However, the stand includes a columnar member extending upward in the vertical direction. A digital force gauge (FGP-5: manufactured by Nidec-Shimpo Co., Ltd.) in which a columnar jig (diameter 2 mm x length 100 mm) is connected to the tip of a stylus is attached to the columnar member. The jig is arranged above the hole of the sample table in the vertical direction so that its tip is in contact with the measurement target area of the sample. At this time, the jig can move perpendicularly to the plane direction of the sample and push the sample in the thickness direction T.
(4) The jig is moved downward in the vertical direction at a speed of 30 mm / min, and the measurement target area of the sample is pushed in by 1 mm in the thickness direction T. Record the maximum load (N) measured by the digital force gauge at that time.
(5) by sequentially changing the measurement area in the first longitudinal folds A 1, repeated measurements (1) to (4), measuring a first overall longitudinal folds A 1.
(6) With N different samples (N is a natural number of 3 or more), the measurements of (1) to (5) are repeated, and the average value thereof is adopted as the pushing force.

なお、側部と中間部との間の剛性(又は変形し難さ)の比較は、側部及び中間部が含む層の数や種類により行うこともできる。例えば、側部63は、中間部61が含まない層(例示:粘着部72、剥離シート82、粘着部92)及び含んでも数が少ない層(例示:温感剤保持シート13)を含んでいる。したがって、側部63は明らかに中間部61よりも相対的に剛性が高い(又は変形し難い)ということができる。あるいは、側部63が、明らかに剛性が高い(又は変形し難い)補強部材を含んでおり、中間部61が含んでいなければ、側部63は明らかに中間部61よりも相対的に剛性が高い(又は変形し難い)ということができる。 The rigidity (or difficulty of deformation) between the side portion and the intermediate portion can be compared according to the number and types of layers included in the side portion and the intermediate portion. For example, the side portion 63 includes a layer that does not include the intermediate portion 61 (example: adhesive portion 72, release sheet 82, adhesive portion 92) and a layer that includes a small number (example: warming agent holding sheet 13). .. Therefore, it can be said that the side portion 63 is clearly relatively more rigid (or less likely to be deformed) than the intermediate portion 61. Alternatively, if the side portion 63 includes a reinforcing member that is clearly rigid (or hard to deform) and the intermediate portion 61 does not, the side portion 63 is clearly relatively stiffer than the intermediate portion 61. Can be said to be high (or difficult to deform).

別の実施形態では補強部材(例示:温感剤保持シート13、粘着部72、剥離シート82及び粘着部92など)の一部は、一対の側部63、63の各々から、隣接する中間部61の幅方向Wの端部まで延出している。すなわち、補強部材が側部63から、その側部63に隣接する中間部61の端縁を越えて中間部61の内部(ただし、端部の範囲)まで延出している。そのため、側部63を摘んで第2長手方向折り畳み部Aから引き離そうとする力を加えたとき、その力を粘着テープ45により確実に伝達することができる。すなわち、使用者は、より容易に、個包装体Pを開封することが可能となる。なお、端部とは全体の両端縁から全体の30%の範囲をいう。In another embodiment, a part of the reinforcing member (eg, the warming agent holding sheet 13, the adhesive portion 72, the release sheet 82, the adhesive portion 92, etc.) is an intermediate portion adjacent to each of the pair of side portions 63, 63. It extends to the end of the width direction W of 61. That is, the reinforcing member extends from the side portion 63 beyond the edge of the intermediate portion 61 adjacent to the side portion 63 to the inside of the intermediate portion 61 (however, the range of the end portion). Therefore, upon addition of separating force applied for a minimum from the second longitudinal folding unit A 2 picking side portion 63 can be reliably transmitted by the adhesive tape 45 to the force. That is, the user can more easily open the individual package P. The end portion means a range of 30% of the whole from both end edges of the whole.

本実形態の好ましい態様として、第2長手方向折り畳み部Aにおける第2幅方向折線Fの側の第3端部E22とは長手方向Lの反対側に位置する第4端部E21が、第1幅方向折線Fと離間している。そのため、使用者は、開封時に第1長手方向折り畳み部Aと長手方向中央部Aとの間の隙間に指を入れ易く、したがって個包装体Pを開封し易い。As a preferred embodiment of the present embodiment, the fourth end portion E 21 located on the opposite side of the longitudinal direction L from the third end portion E 22 on the side of the second width direction folding line F 4 in the second longitudinal folding portion A 2. but it is separated from the first widthwise fold line F 3.

次に、本実施形態に係る生理用ナプキン1の好ましい使用方法について説明する。
装着者が生理用ナプキン1を装着する場合、まず、吸収本体3の吸収体11の***口当接域21が装着者の***口に対応するように、生理用ナプキン1を着衣(例示:ショーツ)に固定する。それにより、温感本体5の温感剤保持シート13が装着者の下腹部に対応するように生理用ナプキン1が着衣に固定される。そして、温感本体5の肌側の面が装着者の下腹部の肌に接した状態で、生理用ナプキン1が使用される。
Next, a preferable method of using the sanitary napkin 1 according to the present embodiment will be described.
When the wearer wears the sanitary napkin 1, first, the sanitary napkin 1 is worn so that the excretion port contact area 21 of the absorber 11 of the absorption body 3 corresponds to the wearer's excretion port (example: shorts). ). As a result, the sanitary napkin 1 is fixed to the clothes so that the warming agent holding sheet 13 of the warming body 5 corresponds to the lower abdomen of the wearer. Then, the sanitary napkin 1 is used in a state where the skin-side surface of the warmth body 5 is in contact with the skin of the wearer's lower abdomen.

言い換えると、生理用ナプキン1は、吸収体11の***口当接域21が装着者の***口に当接するように吸収本体3が着衣に配置されたとき、温感剤保持シート13が装着者の下腹部に対応する位置に配置されるような形状を有している。したがって、吸収本体3の吸収体11の***口当接域21と、温感本体5の温感剤保持シート13との距離は、装着者の***口と、下腹部との距離(肌面上の距離)とに概ね等しい。 In other words, in the sanitary napkin 1, when the absorption body 3 is arranged on the clothes so that the excretion port contact area 21 of the absorber 11 abuts on the wearer's excretion port, the warming agent holding sheet 13 is attached to the wearer. It has a shape that is arranged at a position corresponding to the lower abdomen. Therefore, the distance between the excretion port contact area 21 of the absorber 11 of the absorption body 3 and the warming agent holding sheet 13 of the warmth body 5 is the distance between the wearer's excretion port and the lower abdomen (on the skin surface). Distance) is approximately equal to.

本実施形態では、温感剤保持シート13の温感剤50(機能剤)は、TRPチャネルを活性化する温感成分と、溶媒成分とを含んでいる。そのため、生理用ナプキン1が着衣に固定され、使用されると、温感剤保持シート13に含まれる温感剤50が、液透過性シート7を透過して、装着者の肌に接触し、装着者の肌において、温感成分が接触している温感剤接触部分のTRPチャネルを効率よく活性化し、装着者の下腹部に温感を効率よく付与することができる。 In the present embodiment, the warming agent 50 (functional agent) of the warming agent holding sheet 13 contains a warming component that activates the TRP channel and a solvent component. Therefore, when the sanitary napkin 1 is fixed to the clothes and used, the warming agent 50 contained in the warming agent holding sheet 13 permeates through the liquid permeable sheet 7 and comes into contact with the wearer's skin. It is possible to efficiently activate the TRP channel of the warming agent contact portion in contact with the warming component on the wearer's skin, and efficiently impart warmth to the wearer's lower abdomen.

装着者の下腹部に温感を付与することにより、装着者の下腹部の肌における温感成分に接していた温感剤接触部分のTRPチャネルが活性化される結果、交感神経系を介して、温感剤接触部分から熱が生じ、装着者の肌における温感成分の接触部分の温度を上昇させることが期待できる。その結果、装着者の子宮に近い部位を温め、痛み物質プロスタグランジンを排出させ、装着者の生理痛を緩和することが期待される。装着者の子宮に近い部位を温めることにより、装着者の月経前症候群(Premenstrual Syndrome)、冷え性、更年期障害等を軽減することが期待される。血行促進(リンパの流れの促進)により老廃物排出と冷え改善、脂肪燃焼向上、免疫力向上などが期待される。 By imparting a warm feeling to the wearer's lower abdomen, the TRP channel of the warming agent contact portion that was in contact with the warmth component in the skin of the wearer's lower abdomen is activated, and as a result, via the sympathetic nervous system. , Heat is generated from the contact portion of the warming agent, and it can be expected that the temperature of the contact portion of the warming component on the wearer's skin is raised. As a result, it is expected to warm the part of the wearer near the uterus, discharge the pain substance prostaglandin, and relieve the wearer's menstrual pain. By warming the part of the wearer near the uterus, it is expected to reduce the wearer's premenstrual syndrome, poor circulation, and menopausal disorders. By promoting blood circulation (promoting lymphatic flow), it is expected to excrete waste products, improve coldness, improve fat burning, and improve immunity.

上記各実施形態において、所定の機能を有する機能層(例示:温感剤保持シート13)が有する機能剤(例示:温感剤50)に含まれる機能成分は温感成分である。しかし、本発明はこの例に限定されず、機能成分の種類は他の種類であってもよく、例えば、冷感剤の冷感成分や発熱剤の発熱成分であってもよい。冷感剤を用いる場合、機能層は、例えば、冷感成分と溶媒成分とを含む冷感剤を有するシートである。発熱剤を用いる場合、機能層は、例えば、発熱成分と溶媒成分とを含む発熱剤を有するシートである。また、所定の機能が保温機能の場合、機能層は保温性の高い(例示:温められた空気を保持し易い)不織布のようなシートであり、機能剤は必ずしも含まない。 In each of the above embodiments, the functional component contained in the functional agent (example: warming agent 50) contained in the functional layer having a predetermined function (example: warming agent holding sheet 13) is a warming component. However, the present invention is not limited to this example, and the type of the functional component may be another type, for example, a cooling sensation component of a cooling sensation agent or an exothermic component of an exothermic agent. When a cooling sensation agent is used, the functional layer is, for example, a sheet having a cooling sensation agent containing a cooling sensation component and a solvent component. When an exothermic agent is used, the functional layer is, for example, a sheet having an exothermic agent containing an exothermic component and a solvent component. When the predetermined function is a heat retaining function, the functional layer is a non-woven fabric-like sheet having high heat retaining properties (example: easily holding warm air), and does not necessarily contain a functional agent.

機能剤は、生理用ナプキン1が使用されるまでに揮発したり、他の領域へ移動したりすることを防止するため、水崩壊性の保護材、例えば、マイクロカプセルに保護されていてもよい。マイクロカプセルは、機能剤を内包し、液体(例示:経血、尿、汗)に触れると崩壊し、機能剤を外部に放出させる。放出された機能剤は、着用者の体温等により気化したり、着用者の肌に接触したりすることで、着用者に対して所定の機能を発揮する。 The functional agent may be protected by a water-disintegrating protective material, such as microcapsules, to prevent the sanitary napkin 1 from volatilizing or moving to other areas before use. ..
