In the present embodiment, the embossed portion 27 is formed so as to surround at least the excretion opening contact area, preferably further outside in the longitudinal direction L thereof. However, the excretion port contact area may change depending on the shape of the absorber 11, for example, in the longitudinal direction L, the range of the flap portion 23 or the range of the central 1/3 of the absorber 11, and in the width direction W, the absorber 11 It is an area defined by the range of the central 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 absorber 11 and the warming solution holding sheet 13 are joined with an adhesive (example: hot melt adhesive) or the like. The non-skin side surface of the absorber 11 and the shape-retaining member 15 and the skin side surface of the liquid impermeable sheet 9 are joined with an adhesive or the like. Further, the peripheral edge of the non-skin side surface of the liquid permeable sheet 7 and the peripheral edge of the skin side surface of the liquid permeable sheet 9 are joined by an adhesive or the like. The non-skin side surface of the warming 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, 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). Next, since the absorbing body 3 has the same shape as a normal sanitary napkin, the absorbing body 11 of the absorbing body 3 corresponds to the excretion opening contact area (not shown) of the wearer A. While removing the wrapping sheet 29, the sanitary napkin 1 is fixed to the clothing 19 (example: shorts). As a result, the sanitary napkin 1 is fixed to the clothing 19 so that the warming body 5, particularly the warming 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, in the sanitary napkin 1, when the absorption body 3 is arranged on the clothes 19 so that the excretion port contact area (not shown) of the absorber 11 contacts the excretion port contact area of the wearer A. The warming solution holding sheet 13 has a shape such that it is arranged at a position corresponding to the lower abdomen of the wearer A. Therefore, the distance between the excretion port contact area (not shown) of the absorber 11 of the absorption body 3 and the warmth solution holding sheet 13 of the warmth body 5 is the distance between the wearer's excretion port and the lower abdomen. Approximately equal to (distance on the skin).

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 clothing 19 and used, the warm sensation solution contained in the warm sensation solution holding sheet 13 permeates through the liquid permeable sheet 7 and comes into contact with the skin of the wearer A. , The TRP channel of 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 the warmth can be efficiently imparted to the lower abdomen of the wearer.

By imparting a feeling of warmth to the wearer's lower abdomen, the TRP channel of the part of the skin of the wearer's lower abdomen that was in contact with the warming agent is activated, and as a result, through the sympathetic nervous system. Therefore, it can be expected that heat is generated from the warming agent contact portion and the temperature of the warming agent contact portion of the wearer's skin is raised. As a result, it is expected to warm the part of the wearer near the uterus, excrete the pain substance prostaglandin, and relieve the wearer's menstrual pain. In addition, it is expected to reduce the wearer's premenstrual syndrome (Premenstrual Syndrome), poor circulation, menopausal disorder, etc. by warming the part close to the wearer's uterus. In addition, promotion of blood circulation (promotion of lymphatic flow) is expected to improve waste product discharge and coldness, improve fat burning, and improve immunity.

Next, the packaging method of the individual package K according to the present embodiment will be described.
5 and 6 are schematic views showing a packaging method of the individual package K according to the present 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 it 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 fourth region S ₄ in the width direction may be folded onto the first region S _{1 in} the width direction. As a result, the individual package K of the sanitary napkin 1 in which the sanitary napkin 1 is packaged on the packaging sheet 29 is formed.

Here, when a sanitary napkin having a warming solution containing a fluid component is wrapped in a packaging sheet to form an individual package, an area in which the sanitary napkin warming solution is arranged in the packaging sheet of the individual packaging. The fluid component of the warming solution may volatilize or flow from the sanitary napkin and then adhere to another improper 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, since the excretion port contact area abuts on the excretion port sensitive to a drug or the like, there is a risk of causing discomfort to the wearer depending on the type of the fluid component. On the other hand, when the fluid component of the warming solution volatilizes or moves, the inside of the packaging sheet of the individual package is partially separated by heat seal or emboss seal so that it does not move to an inappropriate area. It's difficult to do. Further, if the amount of the fluid component is reduced or the region 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 region of the sanitary napkin 1 in the above, a warming 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, at the end of the individual package K on the width direction second region S ₂ side in the longitudinal direction L of the width direction first region S ₁ , there is a gap in the sanitary napkin 1 through which the fluid component can move to another region. There is almost no including it, and it can be seen that it is blocked 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 seen that it is almost obstructed. 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, even if the warm sensation solution holding sheet 13 is arranged in the region of the sanitary napkin 1 in at least one of the width direction first region S ₁ and the width direction second region S ₂ , the fluid from the warm sensation solution holding sheet 13 It is possible to prevent the components from volatilizing or flowing and moving to another region in the sanitary napkin 1 and adhering to them. That is, in the individual package of the sanitary napkin 1 provided with the warm sensation solution holding sheet 13, the fluid component of the warm sensation solution holding sheet 13 adheres to another region of the sanitary napkin 1 while maintaining the effect of the warm sensation component. Can be suppressed.

As a preferred embodiment in the above embodiment, in the individual package K, in the thickness direction T, the width direction first region S ₁ is the width direction second region S ₂ and the remaining region (example: width direction third region S ₃ or width). It is positioned between the direction the 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 It can be seen that it has been done. That is, the region of the sanitary napkin ₁ in the first region 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 It is possible to further suppress the movement and adhesion to another region of the. 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 region 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 viewpoint is to more reliably suppress the transfer of the fluid component to the excretion port contact area.
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 embodiment is, for example, an individual package in which a sanitary napkin 1 is folded at three places and folded in four. However, this 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, in the width direction first fold line F _{L1 ~} widthwise third fold line F _L3 while adjusting the position in the longitudinal direction L, more than one in the rear of the longitudinal direction L than the widthwise third fold 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.

A plan view of another configuration example of such an individual package 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 integrates the remainder region (where the width direction third region S ₃₎ is set to. 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 It includes S ₂ and a third region S _{3 in} the width direction (also referred to as a remaining 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.

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 width direction third region S ₃ is located closer to the width direction second region S ₂ than the width direction first region S ₁ , but the width direction first region S _2. S ₁ may be located closer to the second region S _{2 in} the width direction than the third region S _{3 in the} width direction. 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.

As an example, the above embodiment is applied to a sanitary napkin 1 in which a warm feeling main body 5 or a warm feeling solution holding sheet 13 is provided in front of the absorption main body 3 in the longitudinal direction L. However, this embodiment is not limited to this example. For example, the warm sensation main body 5 or the warm sensation solution holding sheet 13 can be similarly applied to the sanitary napkin 1 provided behind the longitudinal direction L in the absorption main body 3 only 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 The region may have other functional agents containing other fluid components. For example, in the sanitary napkin 1, the warm sensation main body 5 or the warm sensation 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 position of _L3 .
