In the present embodiment, the first fold line F _L1 is the width direction, in the deployed state of the sanitary napkin 1 and the package sheet 29, and warming the solution holding sheet 13 is disposed so as to overlap in the thickness direction T . The first longitudinal fold line F _V1 and the second longitudinal fold line F _V2 do not overlap with the absorber 11 in the thickness direction T in the unfolded state of the sanitary napkin 1 and the packaging sheet 29, but the warm solution holding sheet 13 And are arranged so as to overlap in the thickness direction T.

  Further, the sanitary napkin 1 includes a seal portion 25 and an emboss portion 27. The seal portion 25 joins and seals the liquid-permeable sheet 7 and the liquid-impermeable sheet 9 at their outer edges by a method known in the art such as heat sealing. In the present embodiment, the embossed portion 27 is formed so as to surround at least the excretion opening contact area, and preferably to further surround the outside in the longitudinal direction L. However, the excretion opening contact area may vary depending on the shape of the absorber 11 and the like. For example, in the longitudinal direction L, the range of the substantially flap portion 23 or the center 1/3 of the absorber 11, and in the width direction W, the absorber 11 Is an area defined by a range of 1/3 of the center of the area.

  In the sanitary napkin 1, the non-skin side surface of the liquid-permeable sheet 7 and the skin side surfaces of the absorbent body 11 and the warm solution holding sheet 13 are joined with an adhesive (eg, a hot melt adhesive) or the like, The non-skin side surface of the absorber 11 and the shape maintaining member 15 and the skin side surface of the liquid impermeable sheet 9 are joined with an adhesive or the like. In addition, the periphery of the non-skin side surface of the liquid-permeable sheet 7 and the periphery of the skin side surface of the liquid-impermeable sheet 9 are joined with an adhesive or the like. The non-skin side surface of the warm solution holding sheet 13 and the skin side surface of the shape holding member 15 are joined 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, when the wearer A wears the sanitary napkin 1, first, the joining is performed by the adhesive portion (not shown) between the _first width direction region S ₁ and the fourth width direction region S _4. Is removed, and the individual package body K is put into a developed state (FIG. 1). Next, since the absorbent main body 3 has the same shape as a normal sanitary napkin, the absorbent body 11 of the absorbent main body 3 corresponds to the excretion 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 (for example, shorts). As a result, the sanitary napkin 1 is fixed to the clothes 19 such that the warm sensation body 5, particularly the warm sensation 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 warm feeling main body 5 is in contact with the skin of the lower abdomen of the wearer A.

  In other words, when the sanitary napkin 1 is arranged on the clothes 19 such that the excretion port contact area (not shown) of the absorbent body 11 contacts the excretion port contact area of the wearer A, It has a shape such that the warming solution holding sheet 13 is arranged at a position corresponding to the lower abdomen of the wearer A. Therefore, the distance between the excretion opening contact area (not shown) of the absorber 11 of the absorbent main body 3 and the warming solution holding sheet 13 of the warming main body 5 is the distance between the excretion opening of the wearer and the lower abdomen. (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) for activating the TRP channel and a solvent (solvent component). Therefore, when the sanitary napkin 1 is fixed to the clothes 19 and used, the warming solution contained in the warming solution holding sheet 13 passes through the liquid permeable sheet 7 and comes into contact with the skin of the wearer A. In addition, the TRP channel in the warming agent contact portion of the skin of the wearer A, which is in contact with the warming agent, can be efficiently activated, and a warm feeling can be efficiently imparted to the lower abdomen of the wearer.

  By imparting a warm feeling to the lower abdomen of the wearer, the TRP channel of the warming agent contacting portion of the lower abdominal skin of the wearer that has been in contact with the warming agent is activated, and as a result, the TRP channel is passed through the sympathetic nervous system. As a result, heat is generated from the contact portion of the warming sensate, and it can be expected that the temperature of the contact portion of the warming agent on the wearer's skin is increased. As a result, it is expected that the part near the uterus of the wearer will be warmed, the pain substance prostaglandin will be excreted, and the menstrual pain of the wearer will be alleviated. In addition, by warming a part close to the uterus of the wearer, it is expected that premenstrual syndrome, chilliness, menopause, and the like of the wearer are reduced. In addition, the promotion of blood circulation (promotion of lymph flow) is expected to improve waste discharge and cooling, improve fat burning, and improve immunity.

Next, a method for packaging the individual package K according to the present embodiment will be described.
FIG. 5 and FIG. 6 are schematic views illustrating a method of packaging the individual package K according to the present embodiment. First, the sanitary napkin 1 is placed on the packaging sheet 29 as shown in FIG. 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 in. 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. Thereby, the individual package K of the sanitary napkin 1 in which the sanitary napkin 1 is wrapped in the wrapping sheet 29 is formed.

  Here, when a sanitary napkin having a warming solution containing a fluid component is packaged in a packaging sheet to form an individual package, an area where the warming solution of the sanitary napkin is arranged in the packaging sheet of the individual package. The fluid component of the warming solution may volatilize or flow and subsequently adhere to another inappropriate area within the sanitary napkin. For example, when a warming solution is placed at the longitudinal end of a sanitary napkin, the fluid component of the warming solution may volatilize or flow, and then adhere to the excretion opening contact area. In such a case, the excretion opening contact area comes into contact with the excretion opening that is sensitive to the medicine or the like, and therefore, depending on the type of the fluid component, the wearer may feel uncomfortable. Nevertheless, in order to prevent the fluid component of the warming solution from evaporating or moving to an inappropriate area, the inside of the packaging sheet of the individual package is partially separated by a heat seal or an emboss seal. It is difficult to do. Further, when 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 shown in FIG. 1, a warm solution holding sheet 13 containing a 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, 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 of the individual packaging body K is movable fluid component in a different region gap sanitary napkin 1 Almost no, including it, can be seen to be somewhat occluded. 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 No, it can be seen that it is almost occluded. 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, be 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 It can be suppressed that the components volatilize or flow and move to another region in the sanitary napkin 1 and adhere thereto. That is, in the individual package of the sanitary napkin 1 provided with the warming solution holding sheet 13, the fluid component of the warming solution holding sheet 13 adheres to another area of the sanitary napkin 1 while maintaining the effect of the warming 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 Direction fourth region 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 that it is. That is, the area of the sanitary napkin ₁ in the first area S1 in the width direction is a more closed space. Therefore, be arranged Yutakakan solution holding sheet 13 in the width direction first region S _1, or dissipated to the outside fluid components from their warming solution holding sheet 13 is volatilized or flow to, sanitary napkin 1 Can be further suppressed from moving to and adhering to another area. That is, in the individual package of the sanitary napkin 1 including the warming solution holding sheet 13, the fluid component of the warming 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 excretion port, the transfer of the fluid component to the excretion port contact area is more reliably suppressed.
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 above-described embodiment is, as an example, an individual package body in which the sanitary napkin 1 is folded in three places and folded in four. 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 position of the first fold line F _{L1 in the} width direction to the third fold line FL _{3 in} the width direction in the longitudinal direction L, at least one more fold line is provided behind the third fold line FL _{L3 in the} longitudinal direction. by placing the widthwise fold line F _L, the number of folding the individual package may be further increased to five or more.

FIG. 7 shows a plan view of another configuration example of such an individual package K. 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 are integrated to form a remaining area (here, third area S _{3 in} the width direction). In this case, the individual packaging body K, as shown in FIG. 7, a first fold line _{F V1} and second longitudinal fold line _{F V2} longitudinal direction and a width direction first fold line _{F L1} and a width direction second fold 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 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.

FIG. 8 shows a perspective view of such an individual package K in a folded state. As shown in FIG. 8, the sanitary napkin 1 is packaged with a sheet 29, respectively folded longitudinal first fold lines F _V1 and second longitudinal fold line F _V2 as a key, and the width direction first 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, the third region S ₃ in the width direction is located closer to the second region S _{2 in} the width direction than the first region S ₁ in the width direction. 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 above embodiment is applied to the sanitary napkin 1 in which the warming main body 5 or the warming solution holding sheet 13 is provided in the longitudinal direction L of the absorbent main body 3 as an example. However, the present embodiment is not limited to this example. For example, the same applies to the sanitary napkin 1 in which the warming body 5 or the warming solution holding sheet 13 is provided behind the absorbent body 3 in the longitudinal direction L, just by reversing the front-back relationship. .

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 May have another functional agent containing another fluid component. For example, in the sanitary napkin 1, the warming body 5 or the warming solution holding sheet 13 may be provided not only in front of the absorbent body 3 in the longitudinal direction L but also in the rear.
At this time, further, the front end in the longitudinal direction L of the _third third region S3 in the width direction is folded at the position of the second folding line F _L2 in the longitudinal direction, and the rear end is folded at the third folding line F in the width direction. It is folded at the position of _L3 . 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 No, it can be seen that it is almost occluded. 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 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 occluded.

That is, in the individual package K of the sanitary napkin 1 including the warming solution holding sheet 13 and another functional layer, the fluid component of the functional layer is transferred to another area of the sanitary napkin 1 while maintaining the effect of the functional component. Adhesion can be suppressed.

As a preferable mode in each of the above embodiments, both ends of the packaging sheet 29 in the longitudinal direction L are longer outside the longitudinal direction L than both ends of the sanitary napkin 1 in the longitudinal direction L.
Therefore, outside the both ends of the sanitary napkin 1, the packaging sheets 29 can adhere to each other. 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, can be more closing the ends of the longitudinal direction L in the width direction first region S _1. Accordingly, even if the warming solution holding sheet 13 is disposed in the sanitary napkin ₁ in the widthwise first region S1, the fluid component volatilizes or flows from the warming solution holding sheet 13 and dissipates to the outside. Or moving and adhering to another area in the sanitary napkin 1 can be further suppressed.

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 ends may be sealed with a heat seal, an emboss seal, or the like. 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. Accordingly, even if the warming solution holding sheet 13 is disposed at least in the region of the sanitary napkin ₁ in the width direction first region S1, the fluid component volatilizes or flows from the warming solution holding sheet 13 to the outside. Dispersion and movement to another area in the sanitary napkin 1 and adhesion 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 a sealing process such as heat sealing. Therefore, it is possible to prevent the fluid component from being volatilized by the heat of the sealing step and dissipating to the outside from the opening, or from adhering to another region in the sanitary napkin 1. Further, generation of a sound at the time of opening can be suppressed. In another embodiment, both ends in the width direction W may be sealed with a heat seal or the like.

I have. Therefore, it is possible to more accurately form the amount of the fluid component and the region and the position of the warm-feeling solution holding sheet 13. Thereby, while maintaining the effect of the warming solution holding sheet 13 more accurately, the movement of the fluid component of the warming solution holding sheet 13 to another area of the sanitary napkin 1 can be more accurately suppressed. .

  As a preferable aspect in each of the above embodiments, in the individual package K, the packaging sheet 29 is liquid-impermeable. Therefore, the fluid component volatilizes or flows from the warm-feeling solution holding sheet 13, passes through the packaging sheet 29 and dissipates outside, or moves to another area in the sanitary napkin 1 and adheres. It can be more suppressed. That is, in the individual package K of the sanitary napkin 1 including the warming solution holding sheet 13, the fluid component of the warming 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.
