Hereinafter, the individually-wrapped body of the sanitary napkin will be described as an example of the individually-wrapped body of the absorbent article according to the embodiment. Moreover, a warm feeling function is demonstrated as an example of the predetermined | prescribed function which an absorbent article has. The warm feeling function is a function to make the wearer perceive a warm feeling through the skin, and is realized by, for example, a warm feeling solution held in a sheet or the like.

The structure of the sanitary napkin 1 which concerns on this embodiment is demonstrated.
FIG. 1 to FIG. 4 are diagrams showing a configuration example of an individual wrapping body K according to the present embodiment. 1 shows a plan view of the unfolded individual wrapping body K, FIG. 2 shows its exploded perspective view, FIG. 3 shows a schematic view of its worn state, and FIG. 4 shows a perspective view of the folded individual wrapping body K Figure shows. The individual wrapping body K has a longitudinal center line CL having a longitudinal direction L, a width direction W and a thickness direction T orthogonal to one another and extending in the longitudinal direction L through the center of the width direction W. And a packaging sheet 29 for wrapping the sanitary napkin 1. The longitudinal direction L, the width direction W, and the thickness direction T of the individual wrapping body K are similarly applied to the sanitary napkin 1, the respective materials thereof, and the packaging sheet 29. In addition, assuming that the sanitary napkin 1 is worn, in the sanitary napkin 1 and its respective materials, the side relatively closer to the skin is also referred to as the skin side, and the side relatively away from the skin is also referred to as the non-skin side. .

In the packaging sheet 29, both ends in the longitudinal direction L are longer on the outside in the longitudinal direction L than both ends in the longitudinal direction L of the sanitary napkin 1, and both ends in the width direction W are the width of the sanitary napkin 1. It is formed to be longer outside in the width direction W than both end portions in the direction W. That is, when the sanitary napkin 1 is placed on the packaging sheet 29, the sanitary napkin 1 protrudes outside the packaging sheet 29 in plan view, that is, when the sanitary napkin 1 is viewed from above in the thickness direction T. It can be placed so as not to be.

The sanitary napkin 1 includes an absorbent main body 3 and a thermal sensation main body 5 disposed forward of the absorbent main body 3 in the longitudinal direction L. In the absorbent main body 3, the sanitary napkin 1 is a liquid-permeable sheet 7 that abuts on the wearer's skin when worn, a liquid-impermeable sheet 9 that abuts on the clothes 19 when worn, a liquid-permeable sheet 7 and a liquid impervious And an absorber 11 disposed between the permeable sheets 9. The sanitary napkin 1 also includes a liquid-pervious sheet 7 that abuts on the wearer's skin when worn, a liquid-impervious sheet 9 that abuts on the clothes 19 when worn, and a liquid-pervious sheet 7. And a warm feeling solution holding sheet 13 disposed between the liquid impermeable sheets 9 and a shape holding member 15 disposed closer to the liquid impervious sheet 9 than the warm feeling solution holding sheet 13. The shape holding member 15 is a sheet that supports the warm feeling solution holding sheet 13 and holds the shape of the warm feeling main body 5. And the warm feeling solution holding sheet 13 is formed in the position of the front side of the longitudinal direction L rather than the area | region in which the absorber 11 is provided. In another embodiment, the sanitary napkin 1 may not include the shape holding member 15.

The warm feeling solution holding sheet 13 (functional layer) is composed of a sheet capable of holding a liquid such as a non-woven fabric, and contains a warm feeling solution (not shown). The warming solution (functional agent) stimulates the thermal receptor (thermal sensation receptor) of the skin without heating the wearer's body of the sanitary napkin 1 or the vicinity thereof to warm the wearer. And a solvent (solvent component). The warm feeling solution contains a fluid component which can move from the place where it is placed by the influence of temperature, atmospheric pressure, external force or the like in the form of gas or liquid, for example, at least one of the warming agent and the solvent It contains. In a plan view, the warming solution is contained in the entire warming solution holding sheet 13. The length in the width direction W of the warm feeling solution holding sheet 13 is configured to be longer than the length in the width direction W of the absorber 11. As a result, the effect of the warming solution is spread over a wider area in the width direction W than the absorber 11. In another embodiment, in a plan view, the warming solution is not included in the entire warming solution holding sheet 13 but in a predetermined part, for example, an inner central part excluding the peripheral part.

At this time, in the individual packaging body K, in the thickness direction T, located between the widthwise first region S ₁ is the widthwise direction a second region S ₂ in the width direction fourth region S _4, the fourth region width direction S ₄ is located between the widthwise third region S ₃ in the width direction first region S _1. Then, they are joined together by the adhesive portion (not shown) and the width direction first region S ₁ and the width direction fourth region S _4.

In the present embodiment, the widthwise first fold line F _L1 is disposed so as to overlap the warm feeling solution holding sheet 13 in the thickness direction T in the unfolded state of the sanitary napkin 1 and the packaging sheet 29. . The first longitudinal fold line F _V1 and the second longitudinal fold line F _V2 do not overlap the absorbent body 11 in the thickness direction T in the unfolded state of the sanitary napkin 1 and the packaging sheet 29, but the warm-feeling solution retention sheet 13 And are arranged to overlap in the thickness direction T.

In addition, the sanitary napkin 1 includes the seal portion 25 and the embossed portion 27. The seal portion 25 joins and seals the liquid-permeable sheet 7 and the liquid-impermeable sheet 9 at their outer edge portions by methods known in the art such as heat sealing. In the present embodiment, the emboss portion 27 is formed so as to surround at least the discharge port contact area, preferably to further surround the outside in the longitudinal direction L thereof. However, the discharge port contact area may be changed depending on the shape of the absorber 11, etc. For example, in the longitudinal direction L, the range of the flap portion 23 or the center 1/3 of the absorber 11 and the width direction W The area is defined by the range of the center 1/3 of.

In the sanitary napkin 1, the non-skin side surface of the liquid-permeable sheet 7 and the skin side surface of the absorbent body 11 and the warming solution holding sheet 13 are bonded with an adhesive (example: hot melt adhesive) or the like. The non-skin side surface of the absorber 11 and the shape holding member 15 and the skin side surface of the liquid impermeable sheet 9 are bonded with an adhesive or the like. Further, the peripheral portion of the non-skin side surface of the liquid-permeable sheet 7 and the peripheral portion of the skin-side surface of the liquid impermeable sheet 9 are bonded with an adhesive or the like. The non-skin side surface of the warm feeling solution holding sheet 13 and the skin side surface of the shape holding member 15 are bonded with an adhesive or the like.

Next, a method of using the sanitary napkin 1 according to the present embodiment will be described.
As shown in FIG. 3, if the wearer A wears the sanitary napkin 1, first, bonding by adhesive portion between the widthwise first region S ₁ and the width direction fourth region S ₄ (not shown) Is removed, and the individual package K is in the unfolded state (FIG. 1). Then, the absorbent body 3 has the same shape as a normal sanitary napkin, so that the absorbent body 11 of the absorbent body 3 corresponds to the excretory opening contact area (not shown) of the wearer A, While removing the packaging sheet 29, the sanitary napkin 1 is fixed to the clothes 19 (example: shorts). Thereby, the sanitary napkin 1 is fixed to the clothes 19 so that the warm feeling main body 5, particularly the warm feeling solution holding sheet 13, corresponds to the lower abdomen of the wearer A. Then, the sanitary napkin 1 is used in a state where the skin contact surface of the thermal sensation main body 5 is in contact with the skin of the lower abdomen of the wearer A.

In other words, when the absorbent body 3 is disposed on the clothes 19, the sanitary napkin 1 is arranged such that the excretion opening contact area (not shown) of the absorber 11 abuts on the wearer A's excretion opening contact area, The warming solution holding sheet 13 is shaped so as to be disposed at a position corresponding to the lower abdomen of the wearer A. Therefore, the distance between the excretory opening contact area (not shown) of the absorber 11 of the absorbent main body 3 and the warm feeling solution holding sheet 13 of the warm feeling main body 5 is the distance between the excretory opening of the wearer and the lower abdomen. It is approximately equal to (the distance on the skin surface).

In the present embodiment, the warming solution (functional agent) of the warming solution holding sheet 13 contains a warming agent (warming component) that activates the TRP channel and a solvent (solvent component). Therefore, when the sanitary napkin 1 is fixed to the clothes 19 and used, the warm-feel solution contained in the warm-feel solution holding sheet 13 permeates the liquid-permeable sheet 7 and contacts the skin of the wearer A. The TRP channel of the warming agent contact portion of the skin of the wearer A in contact with the warming agent can be efficiently activated, and the warm feeling can be efficiently provided to the lower abdomen of the wearer.

By giving warmth to the lower abdomen of the wearer, as a result of activating the TRP channel of the warming agent contact portion of the skin on the lower abdomen of the wearer, which is in contact with the warming agent, It can be expected that heat will be generated from the heat sensitive agent contact portion and the temperature of the heat sensitive agent contact portion of the wearer's skin will be raised. As a result, it is expected that the region near the wearer's uterus is warmed, the pain substance prostaglandin is excreted, and the wearer's menstrual pain is alleviated. In addition, it is expected that the premenstrual syndrome, coldness, menopausal disorder and the like of the wearer will be alleviated by warming the site close to the womb of the wearer. Further, it is expected to improve waste discharge and cooling, improve fat burning, improve immunity, etc. by promoting blood circulation (promoting the flow of lymph).

Next, the packaging method of the individual wrapping body K which concerns on this embodiment is demonstrated.
FIG.5 and FIG.6 is a schematic diagram which shows the packaging method of the individual wrapping body K which concerns on this embodiment. First, as shown in FIG. 5A, the sanitary napkin 1 is placed on the packaging sheet 29. Then, as shown in FIG. 5 (b), the sanitary napkin 1 and the package sheet 29, the longitudinal direction of the first fold line _{F V1} as a key, the first longitudinal region _{P 1,} second longitudinal region _{P 2} above Fold. Then, as shown in FIG. 6 (a), as a key a second longitudinal fold line _{F V2,} a longitudinal third region _{P 3,} folded over second longitudinal region _{P 2.} However, the order of folding the first longitudinal region P ₁ and the longitudinal third region P ₃ may be reversed. Then, as shown in FIG. 6 (b), as a key width direction first fold line F _L1, a width direction first region S _1, together with the folded over the width direction second region S _2, widthwise third fold line F the _L3 as a key, the widthwise fourth region _{S 4,} folded on a width direction third region _{S 3.} Thereafter, as shown in FIG. 6 (c), as a key width direction second fold line _{F L2,} the width direction first region _{S 1,} folded over the width direction fourth region _{S 4.} However, the width direction fourth region S _4, may be folded in the width direction first upper region S _1. As a result, an individual package K of the sanitary napkin 1 in which the sanitary napkin 1 is packaged in the packaging sheet 29 is formed.

Here, when a sanitary napkin having a warm feeling solution containing a fluid component is packaged with a packaging sheet to form an individual package, an area where the warm feeling solution of the sanitary napkin is disposed in the packaging sheet of the individual package. The fluid component of the warm feeling solution may volatilize or flow and then adhere to another inappropriate area in the sanitary napkin. For example, when the warming solution is disposed at the longitudinal end of the sanitary napkin, the fluid component of the warming solution may volatilize or flow and thereafter adhere to the discharge port contact area. In such a case, the discharge port contact area is in contact with the discharge port sensitive to a drug or the like, and depending on the type of the fluid component, the wearer may feel discomfort or the like. However, in order to prevent the fluid component of the warming solution from migrating to an inappropriate area when volatilized or moved, the inside of the packaging sheet of the individual package is partially divided by heat sealing or embossing sealing. It is difficult to do. In addition, if the amount of the fluid component is reduced or the area of the warming solution is reduced, the effect of the warming component may be reduced.

Therefore, in the individual packaging body K according to the present embodiment, at least one of the width direction first fold line F _L1 width direction first partitioned by _~ widthwise second fold line F _L2 region S ₁ and the width direction second region S ₂ In the area of the sanitary napkin 1 in the above, the warm feeling solution holding sheet 13 containing the fluid component is provided. At this time, the end portion in the width direction the second region S ₂ side of the longitudinal direction L in the width direction first region S ₁ is folded at the position in the width direction first fold line F _L1. Therefore, at the end on the width direction second region S ₂ side in the longitudinal direction L of the width direction first region S ₁ of the individual package K, a gap in which the fluid component can move to another region is inside the sanitary napkin 1 There is almost no inclusion, and it can be seen as being occluded to some extent. The end portion in the width direction first region S ₁ side of the longitudinal direction L in the width direction the second region S ₂ is folded at the position in the width direction first fold line F _L1, widthwise third region S ₃ ( end of the balance region) side is folded at the position in the width direction second fold line F _L2. Thus, the front and rear ends of the longitudinal direction L of the individual packaging body width direction second region S ₂ of K are both fluid component is movable clearance to another area almost including sanitary napkin 1 It can be viewed as almost blocked. That is, the region of the sanitary napkin 1 in the width direction first region S ₁ and the width direction second region S ₂ are both generally set in a closed space.
Therefore, it is arranged Yutakakan solution holding sheet 13 in the region of the sanitary napkin 1 at least one of the width direction first region S ₁ and the width direction second region S _2, fluid from their warming solution holding sheet 13 The components can be prevented from volatilizing or flowing to move to and adhere to another area in the sanitary napkin 1. That is, in the individual wrapping of the sanitary napkin 1 provided with the warm feeling solution holding sheet 13, the fluid component of the warm feeling solution holding sheet 13 adheres to another area of the sanitary napkin 1 while maintaining the effect of the warm feeling component. Can be suppressed.

In a preferred embodiment in the above embodiment, individual in package K, in the thickness direction T, the second region S ₂ and the balance region the first region S ₁ width direction width direction (exemplified the widthwise third region S ₃ or width It is located between the fourth direction S ₄ ). At this time, the ends of the opposite side of the width direction second region S ₂ in the longitudinal direction L in the width direction first region S ₁ is between the width direction second region S ₂ and the rest area in the thickness direction T end of the sandwiched located in occlusive condition, widthwise second region S ₂ side is folded at the position of the first fold line. Thus, both ends in the longitudinal direction L in the width direction first region S ₁ of the individual packaging body K is movable fluid component to the outside or another area gap hardly including sanitary napkin 1, substantially closed You can see it as being done. That is, the area of the sanitary napkin ₁ in the widthwise first area S1 is a more closed space. Therefore, even if the warming solution holding sheet 13 is disposed in the width direction first region S ₁ , fluid components are volatilized or flow from the warming solution holding sheet 13 and dissipated to the outside, or the inside of the sanitary napkin 1 Can be further suppressed from moving to and attaching to another area of That is, in the individual wrapping of the sanitary napkin 1 provided with the warm feeling solution holding sheet 13, the fluid component of the warm feeling solution holding sheet 13 adheres to another area of the sanitary napkin 1 while maintaining the effect of the functional component. Can be suppressed.

In a preferred embodiment in the above embodiment, excretion equivalent towards the amount of warming solution contact zone width direction second region S ₂ close to the, warming a solution of the excretory opening contact region far from the width direction first region S ₁ Less than the amount of. In order to avoid the influence on the excretory port, it is a viewpoint of suppressing the migration of the fluid component to the excretory port contact area more reliably.
Further, the above-described embodiment, as an example, warming the solution holding sheet 13 is disposed in the width direction first region S ₁ and the width direction second region S _2. However, this embodiment is not limited to this example, warming the solution holding sheet 13 be disposed on either one of the width direction first region S ₁ and the width direction second region S ₂ Good.

The said embodiment is an individual wrapping body which folded the sanitary napkin 1 in three places, and made it into four as an example. However, the present embodiment is not limited to this example. For example, by such shifting the position of at least the width direction second fold line F _L2 in the width direction first fold line F _L1 and a width direction second fold line F _L2 behind the longitudinal direction L, the third region S ₃ and the width direction widthwise as 4 balance by integrating the area S ₄ area, folding the sanitary napkin 1 in two locations in the width direction first fold line F _L1 and a width direction second fold line F _L2, even individual packaging body in which the three-fold Good. Further, for example, while adjusting the positions in the longitudinal direction L of the width direction first broken line F _L1 to the width direction third broken line F _L3 , one or more further in the longitudinal direction L rearward than the width direction third broken line F _L3 . by placing the widthwise fold line F _L, the number of folding the individual package may be further increased to five or more.

The top view of the other structural example of such individual packaging body K is shown in FIG. Individual package K, by shifting the position of both the width direction first fold line F _L1 and a width direction second fold line F _L2 behind the longitudinal direction L, the width direction third region S ₃ and the widthwise fourth region S ₄ is integrated and it is set as the remaining area (here, width direction third area S ₃ ). In this case, as shown in FIG. 7, the individual package K includes the first longitudinal broken line F _V1 and the second longitudinal broken line F _V2, and the first transverse broken line F _L1 and the second transverse broken line F _L2 . Have. Individual package K is partitioned in the width direction first fold line F _L1 and a width direction second fold line F _L2, longitudinally one first region width direction arranged on the other side from the side S ₁ of the _L, the width direction second region includes S ₂ and the width direction third region S _{3 (also} referred to as a balance region). However, the width direction first fold line F _L1, for example, is arranged between the absorber 11 and warming the solution holding sheet 13, the second fold line F _L2 width direction, of the sanitary napkin 1 backward (excretory opening contact It is located behind the area). Fold sanitary napkin 1 in two locations in the width direction first fold line F _L1 and a width direction second fold line F _L2, is to have the three-fold individual package K.

A perspective view of such a folded state of the individual wrapping body K is shown in FIG. As shown in FIG. 8, the sanitary napkin 1 is folded together with the packaging sheet 29 using the first longitudinal fold line F _V1 and the second longitudinal fold line F _V2 as base axes, and the first transverse fold line F _L1 and width folded respectively direction second fold line F _L2 as a key, to form a individual package K. At this time, in the individual packaging body K, in the thickness direction T, the width direction third region S ₃ in the width direction second fold line F _L2 is folded on the side of one surface in the width direction the second region S _2, the width direction width first region S ₁ in the first fold line F _L1 is folded on the side of one surface in the width direction the second region S _2. Then, the adhesive part and the width direction first region S ₁ and the widthwise third region S _3:; are joined together by (illustrated lead tape not shown). However, in FIG. 8, in the thickness direction T, although the width direction third region S ₃ are located on the side of the width direction second region S ₂ than the width direction first region S _1, the width direction first region S ₁ is may be positioned on the side in the width direction the second region S ₂ than the widthwise third region S _3. Fluid component in that case, it is possible to sandwich the outer ends of the longitudinal direction L in the width direction first region S ₁ in the width direction third region S ₃ and widthwise second region S _2, warming the solution from which Can be prevented from volatilizing or flowing and leaking. It is also the width direction third region S ₃ in the width direction second fold line F _L2 unfolded on the side of the other surface in the width direction the second region S _2.

The said embodiment is applied to the sanitary napkin 1 in which the warm feeling main body 5 or the warm feeling solution holding sheet 13 was provided ahead of the longitudinal direction L in the absorption main body 3 as an example. However, the present embodiment is not limited to this example. For example, the same can be applied to the sanitary napkin 1 in which the warm feeling main body 5 or the warm feeling solution holding sheet 13 is provided at the rear of the longitudinal direction L in the absorption main body 3 only by reversing the front and rear relation. .

As another embodiment, furthermore, the sanitary napkin 1 in at least one of the width direction second fold line F _{L2 ~} widthwise third fold line F width direction partitioned by the _L3 third area S ₃ and the widthwise fourth region S ₄ In the area of the above, other functional agents containing other fluid components may be included. For example, in the sanitary napkin 1, the warm feeling main body 5 or the warm feeling solution holding sheet 13 may be provided not only in front of the absorption main body 3 in the longitudinal direction L but also in the rear.
In this case, further, the front end portion in the longitudinal direction L in the width direction third region S ₃ are folded at the position in the width direction second fold line F _L2, the rear end portion, the third fold line F width direction It is folded at the _L3 position. Thus, the front and rear ends of the longitudinal direction L in the width direction third region S ₃ of the individual package K are all fluid component is movable clearance to another area almost including sanitary napkin 1 It can be viewed as almost blocked. Further, the front end portion in the longitudinal direction L in the width direction the fourth region S ₄ is folded at the position in the width direction third fold line F _L3, rear end in the width direction first in the thickness direction T It is sandwiched between the region S ₁ and the widthwise third region S _3. Accordingly, front and rear end portions in the width direction fourth region S ₄ of the individual packaging body K are all movable fluid component to the outside or another area gap hardly including sanitary napkin 1, It can be seen that it is almost blocked. That is, the region of the sanitary napkin 1 in the width direction third region S ₃ and the widthwise fourth region S ₄ is generally set in a closed space.

That is, in the individual package K of the sanitary napkin 1 provided with the warm feeling solution holding sheet 13 and the other functional layers, the fluid component of the functional layer is in another region of the sanitary napkin 1 while maintaining the effect of the functional components. It is possible to suppress adhesion.

As a preferable aspect in each said embodiment, the both ends of the longitudinal direction L in the packaging sheet 29 are longer outside the longitudinal direction L than the both ends of the longitudinal direction L in the sanitary napkin 1.
Therefore, the packaging sheets 29 can be in close contact with each other outside the both ends of the sanitary napkin 1. Therefore, for example, one end portion in the longitudinal direction L in the width direction first region S _1, while between the package sheet 29 is in close contact between the widthwise second region S ₂ in the width direction fourth region S ₄ since sandwiched by it, it can be more closing the ends of the longitudinal direction L in the width direction first region S _1. Thereby, even if the warm-feeling solution holding sheet 13 is disposed in the area of the sanitary napkin ₁ in the width direction first area S1, the fluid component volatilizes or flows from the warm-feeling solution holding sheet 13 and dissipates to the outside It is possible to further suppress migration and adhesion to another area in the sanitary napkin 1.

As another embodiment, the end portion in the width direction first region S ₁ side of the longitudinal direction L of the wrapping sheet 29, i.e. the end portion of a side of the warming solution holding sheet 13 may be sealed. For example, the end may be sealed with a heat seal or an embossed seal. Therefore, for example, one end portion in the longitudinal direction L in the width direction first region S _1, while sealed, between the widthwise second region S ₂ in the width direction fourth region S _{4 (or} the remainder region) it means that the sandwiched, it is possible to close the ends of the longitudinal direction L in the width direction first region S _1. Thereby, even if the warming solution holding sheet 13 is disposed at least in the area of the sanitary napkin ₁ in the width direction first region S1, the fluid component is volatilized or flows from the warming solution holding sheet 13 to the outside Dissipation or migration to another area in the sanitary napkin 1 can be further suppressed.

As a preferred embodiment in the above embodiments, the individual packaging body K, as a first longitudinal fold line F _V1 and second longitudinal cornerstone fold line F _V2, the first longitudinal region P ₁ and the longitudinal third region P ₃ by folded longitudinally second upper region P _2, so as not to be moved out or another area fluid component through the both ends in the width direction W, both end portions in the width direction W is closed. That is, both end portions in the width direction W are not closed by the sealing process by heat sealing or the like. Therefore, it is possible to suppress that the fluid component is volatilized by the heat of the sealing process and is dissipated from the opening to the outside or attached to another area in the sanitary napkin 1. In addition, the generation of the sound at the time of opening can be suppressed. In another embodiment, both ends in the width direction W may be sealed by heat sealing or the like.

As a preferred embodiment in the above embodiments, the individual packaging body K, warming the solution holding sheet 13, the sanitary napkin 1 in the absorbent body 11 front longitudinal or width direction first region S ₁ of the rear L than the region Since it is formed in, it can exhibit the function of a warm feeling solution more effectively with respect to the abdomen or the back. And even then, the individual packaging body K is the absorber 11, i.e. the width direction second region S ₂ or widthwise third area S ₃ to the position of the excretory opening contact region (or the remainder region), the width direction since the folded between the first region S _1, the width direction first region warming solution holding the second region S ₂ or widthwise fluid component width direction of the sheet 13 in S ₁ third region S ₃ and width possible to suppress adherence to move to the excretory opening contact region in a direction the fourth region S _{4 (or} the remainder region).

Therefore, the amount of fluid component and the area and position of the warming solution holding sheet 13 can be formed more accurately. Thereby, while maintaining the effect of the warm feeling solution holding sheet 13 more accurately, the fluid component of the warm feeling solution holding sheet 13 can be more appropriately restrained from moving and adhering to another area of the sanitary napkin 1 .

As a preferable aspect in each said embodiment, in the individual packaging body K, the packaging sheet 29 is liquid impervious. Therefore, the fluid component volatilizes or flows from the warm feeling solution holding sheet 13, passes through the packaging sheet 29, and is dissipated to the outside or moved to and adhered to another area in the sanitary napkin 1. It can suppress more. That is, in the individual wrapping body K of the sanitary napkin 1 provided with the warm feeling solution holding sheet 13, the fluid component of the warm feeling solution holding sheet 13 adheres to another area of the sanitary napkin 1 while maintaining the effect of the functional component. Can be further suppressed.
