[The problem to be solved by the invention]

Functional agents include functional ingredients such as warm-sensing ingredients and cooling-sensing ingredients and solvent ingredients. These functional components, solvent components, etc. may contain fluid components in the form of gas, liquid, etc. that can move from the field where they are arranged.

Therefore, consideration is given to the case of packaging an absorbent article provided with a functional layer having a functional agent containing a fluid component to form an individual package with a packaging sheet. In this case, in the packaging sheet of the individual package, the fluid component may volatilize or flow from the area where the functional layer of the absorbent article is arranged, and then may adhere to other inappropriate areas. For example, when a functional layer is arrange|positioned at the edge part of the longitudinal direction of an absorbent article, the fluid component of this functional layer volatilizes or flows, and there exists a possibility that it may adhere to an excretory opening contact area after that. In this case, the excretory port abutting region comes into contact with the excretory port which is sensitive to drugs and the like, and therefore, there is a possibility that the wearer may feel uncomfortable or the like depending on the type of the fluid component. Furthermore, it is difficult to separate the packaging sheets of individual packaging bodies by heat sealing or embossing sealing in order to prevent the fluid components of the functional layer from moving to inappropriate areas when volatilized or moved. In addition, if the amount of the fluid component is reduced or the area of the functional layer is reduced, the effect of the functional component may be reduced.

Therefore, an object of the present invention is to provide an individual package for an absorbent article having a functional layer, which can maintain the effect of the functional component of the functional layer and suppress the adhesion of the fluid component of the functional layer to other areas of the absorbent article. of individual packages.

Also, as shown in FIG. 4 , before use, the sanitary napkin 1, together with the packaging sheet 29, is formed with the first fold line F _V1 in the longitudinal direction, the second fold line F _V2 in the longitudinal direction, and the first fold line _FL1 in the width direction, and the width direction The second folding line _FL2 and the third folding line _FL3 in the width direction are respectively folded as base axes to form a single package K of sanitary napkins. At this time, in the individual package K, in the thickness direction T, the widthwise _first area S1 is located between the widthwise _second area S2 and the widthwise fourth area S4, and the widthwise _fourth area S4 is located between the widthwise second area S2 and the widthwise _fourth area S4. Between the _third region S3 in the width direction and the _first region S1 in the width direction. Moreover, the width direction _1st area|region S1 and the width direction _4th area|region S4 are mutually joined by the adhesive part (not shown).

In addition, in this embodiment, the width direction 1st folding line FL1 is arrange|positioned so that it may overlap in the thickness direction T with the temperature sensitive solution holding|maintenance sheet 13 in the _unfolded state of the sanitary napkin 1 and the packaging sheet 29. The first fold line F _L1 in the longitudinal direction and the second fold line F _V2 in the longitudinal direction are arranged so that they do not overlap with the absorber 11 in the thickness direction T, but are kept with the temperature-sensing solution in the unfolded state of the sanitary napkin 1 and the packaging sheet 29 . The sheets 13 are repeated in the thickness direction T. As shown in FIG.

Moreover, the sanitary napkin 1 is provided with the sealing part 25 and the embossing part 27 . The sealing portion 25 is formed by joining and sealing the liquid-permeable sheet 7 and the liquid-impermeable sheet 9 at the outer edge portions of the sheets by a conventional method in the art, such as heat sealing. In the present embodiment, the embossed portion 27 is formed so as to cover at least the excretion port contact region, and it is desirable to further surround the outer side in the longitudinal direction L. As shown in FIG. Among them, the excretion port contact area can be changed by the shape of the absorber 11 or the like, but, for example, in the longitudinal direction L, it is defined by the range of the flap portion 23 or the range of the center 1/3 of the absorber 11 . The area is an area defined by the range of the center 1/3 of the absorber 11 in the width direction W. As shown in FIG.

In the sanitary napkin 1, the non-skin-side surface of the liquid-permeable sheet 7, the absorber 11 and the skin-side surface of the temperature-sensing solution holding sheet 13 are bonded together with an adhesive (for example, a hot melt adhesive) or the like. The non-skin-side surfaces of the absorber 11 and the shape-retaining member 15 and the skin-side surfaces of the liquid-impermeable sheet 9 are bonded together with an adhesive or the like. Moreover, the peripheral edge part of the non-skin side surface of the liquid-permeable sheet 7 and the peripheral edge part of the skin-side surface of the liquid-impermeable sheet 9 are joined together with an adhesive or the like. The non-skin-side surface of the temperature-sensitive solution holding sheet 13 and the skin-side surface of the shape maintaining member 15 are bonded together with an adhesive or the like.

Next, the usage method of the sanitary napkin 1 concerning this embodiment is demonstrated. As shown in FIG. 3, when the wearer A wears the sanitary napkin 1, first, the adhesive portion (not shown) between the _first region S1 in the width direction and the _fourth region S4 in the width direction is joined together It is eliminated, and the individual package K is made into an expanded state (FIG. 1). Next, since the absorbent body 3 has the same shape as a general sanitary napkin, the absorbent body 11 of the absorbent body 3 is packaged so that the absorbent body 11 of the absorbent body 3 corresponds to the excretion opening contact area (not shown) of the wearer A. The sheet 29 is removed and the sanitary napkin 1 is fixed to the clothing 19 (example: shorts). Thereby, the sanitary napkin 1 is fixed to the clothing 19 so that the warmth-sensing body 5, especially the warmth-sensing solution holding sheet 13, corresponds to the lower abdomen of the wearer A. Moreover, the sanitary napkin 1 is used in the state which the skin contacting surface of the temperature-sensitive main body 5 is already in contact with the skin of the wearer A's lower abdomen.

In other words, the sanitary napkin 1 has a shape that absorbs the absorbent body 11 so that the excretory opening abutting region (not shown) of the absorber 11 comes into contact with the excretion opening abutting region of the wearer A. When the main body 3 is arranged on the clothing 19, the heat-sensing solution holding sheet 13 is arranged in a shape 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 body 3 and the temperature-sensing solution holding sheet 13 of the heat-sensing body 5 is the distance between the excretory opening and the lower abdomen of the wearer (skin surface). distance) are approximately equal.

In the present embodiment, the temperature-sensing solution (functional agent) of the temperature-sensing solution holding sheet 13 contains a temperature-sensing agent (heat-sensing component) for activating TRP channels and a solvent (solvent component). Therefore, when the sanitary napkin 1 is fixed to the clothing 19 and used, the warm feeling solution contained in the warm feeling solution retaining sheet 13 permeates the liquid permeable sheet 7 and comes into contact with the skin of the wearer A, causing the wearer A to The TRP channel in the portion of the skin that is in contact with the warming agent is efficiently activated, and a warm feeling can be efficiently imparted to the lower abdomen of the wearer.

By imparting a feeling of warmth to the lower abdomen of the wearer, as a result of activating the TRP channel in the portion of the skin of the lower abdomen of the wearer that is in contact with the warming agent, it can be expected that the sympathetic nervous system can be activated from the TRP channel. The heat-sensing agent-contacting portion generates heat, and the temperature of the warming-sensing agent-contacting portion of the wearer's skin rises. As a result, the part close to the uterus of the wearer can be warmed, the pain substance prostaglandin can be excreted, and it can be expected to relieve the wearer's physiological pain. In addition, by making the part close to the uterus of the wearer feel warm, it is also expected that the wearer's premenstrual syndrome (Premenstrual Syndrome), sensitivity to cold, menopausal disorders, etc. can be alleviated. In addition, by promoting blood circulation (promoting the flow of lymph), it is also expected that waste discharge and sensitivity to cold are improved, fat burning is improved, and immunity is improved.

Next, the packaging method of the individual package K of this embodiment is demonstrated. FIG. 5 and FIG. 6 are schematic diagrams showing the packaging method of the individual package K of the present embodiment. First, as shown in FIG. 5( a ), the sanitary napkin 1 is placed on the packaging sheet 29 . Next, as shown in FIG. 5( b ), regarding the sanitary napkin 1 and the packaging sheet 29 , the first longitudinal direction region P ₁ is folded to the longitudinal direction second region P ₂ with the longitudinal direction first folding line F _V1 as the base axis. superior. Next, as shown in FIG. 6( a ), the longitudinal third region _P3 is folded on the longitudinal second region P2 with the longitudinal _second folding line F _V2 as the base axis. The folding order of the _first region P1 in the longitudinal direction and the third region _P3 in the longitudinal direction may be reversed. Next, as shown in FIG. 6( b ), the first width direction area S ₁ is folded on the width direction second area S ₂ with the width direction first fold line _FL1 as the base axis, and the width direction third fold line _FL 3 is folded over the width direction second area S 2 . As a base axis, the _fourth region S4 in the width direction is folded on the _third region S3 in the width direction. Then, as shown in FIG.6(c), the width direction _1st area|region S1 is folded on the width direction _4th area|region S4 with the width direction 2nd folding line _FL2 as a base axis. Here, the _fourth region S4 in the width direction may be folded on the _first region S1 in the width direction. Thereby, the individual package body K of the sanitary napkin 1 in which the sanitary napkin 1 is packaged by the packaging sheet 29 is formed.

Here, when an individual package is formed by wrapping a sanitary napkin having a temperature-sensing solution containing a fluid component in a packaging sheet, there is a possibility that the sanitary napkin is placed in the packaging sheet of the individual package, and the sensation of warmth is dislocated from the sanitary napkin. In the area of the solution, there is a risk that the fluid component of the temperature-sensing solution will volatilize or flow, and then adhere to other inappropriate areas in the sanitary napkin. For example, when the temperature-sensing solution is arranged at the end of the sanitary napkin in the longitudinal direction, the fluid component of the temperature-sensing solution may volatilize or flow, and then may adhere to the excretion port contact area. In this case, the excretory port abutting region comes into contact with the excretory port which is sensitive to drugs and the like, and therefore, there is a possibility that the wearer may feel uncomfortable or the like depending on the type of the fluid component. In addition, even if the fluid component of the temperature-sensing solution is volatilized or moved, it is difficult to partially distinguish the inside of the packaging sheet of the individual packaging body by heat sealing or embossing sealing so as not to move to an inappropriate area. . In addition, if the amount of the fluid component is reduced or the area of the temperature-sensitive solution is reduced, the effect of the temperature-sensitive component may be reduced.

Therefore, in the individual package K of the present embodiment, in the _first width direction area S1 and the width direction second area S2 defined by the width direction first fold line _FL1 to the width direction _second fold line _FL2 At least one area of the sanitary napkin 1 has a warm solution holding sheet 13 containing a fluid component. At this time, the edge part on the side of the widthwise _second area S2 in the lengthwise direction _L of the widthwise _first area S1 is folded at the position of the widthwise first folding line FL1. Therefore, the end portion on the side of the _second width direction area S2 in the longitudinal direction L of the width direction _first area S1 of the individual package K has almost no problem even in the area including the sanitary napkin 1. The gaps where fluid components move toward other areas can be considered to be closed to some extent. In addition, the end portion on the side of the _first width direction region S1 in the longitudinal direction _L of the widthwise _second region S2 is folded at the position of the widthwise first folding line FL1, and the widthwise _third region S3 (remaining portion) The end on the area) side is folded at the position of the second folding line _FL2 in the width direction. Therefore, the front and rear ends in the longitudinal direction L of the widthwise _second region S2 of the individual package K, even in the region including the sanitary napkin 1, hardly exist to cause the fluid component to move to other regions The gap can be regarded as almost closed. That is, the area|region of the sanitary napkin 1 of the width direction _1st area|region S1 and the width direction _2nd area|region S2 is formed as a substantially closed space. Therefore, even if the warm solution holding sheet 13 is arranged in the area of the sanitary napkin 1 in at least one of the widthwise _first area S1 and the widthwise _second area S2, it is possible to suppress the fluid component from the isothermal solution from the isothermal solution. The holding sheet 13 evaporates or flows to move and adhere to other areas within the sanitary napkin 1 . That is, in the individual package of the sanitary napkin 1 provided with the warm solution holding sheet 13, the effect of the warm feeling component can be maintained, and the fluid component of the warm solution holding sheet 13 can be suppressed from adhering to the sanitary napkin. 1 other areas.

In the aforementioned embodiment, as an ideal aspect, in the thickness direction T of the individual package K, the widthwise _first region S1 is located in the widthwise _second region S2 and the remainder region (for example: the widthwise third region S1). between the area S ₃ or the fourth area S ₄ in the width direction. At this time, the end portion on the opposite side of the longitudinal direction L of the widthwise _first region S1 and the widthwise _second region S2 is held between the widthwise second region S2 and the remainder region in the thickness direction T. In a closed state, the end of the _second region S2 in the width direction is folded at the position of the first folding line. Therefore, at both ends in the longitudinal direction L of the _first area S1 in the width direction of the individual package K, even in the area including the sanitary napkin 1, there is almost no possibility that the fluid component may move to the outside or other areas. The gap can be considered almost closed. That is, the area|region of the sanitary napkin ₁ of the width direction 1st area|region S1 becomes a more closed space. Therefore, even if the temperature-sensitive solution holding sheet 13 is arranged in the _first region S1 in the width direction, the fluid component can be further suppressed from volatilizing or flowing from the isothermal solution holding sheet 13 and dissipating to the outside, or to the inside of the sanitary napkin 1 . to move and attach to other areas. That is, in the individual package of the sanitary napkin 1 provided with the warm solution holding sheet 13, the effect of the functional component can be maintained, and the fluid component of the warm solution holding sheet 13 can be suppressed from adhering to the sanitary napkin 1. other areas.

In the above-described embodiment, ideally, the temperature of the _second area S2 in the width direction close to the excretion port abutting area is higher than the amount of the temperature-sensitive solution in the widthwise _first area S1 farther from the excretion port abutting area. The amount of the solution is less. This is in order to avoid the influence on the drain port and to suppress the migration of the fluid component to the drain port contact area more reliably. Moreover, in the said embodiment, as an example, the temperature-sensitive solution holding sheet 13 is arrange|positioned in the width direction _1st area|region S1 and the width direction _2nd area|region S2. However, the present embodiment is not limited to this example, and the temperature-sensitive solution holding sheet 13 may be arranged only in _one of the first region S1 in the width direction and the _second region S2 in the width direction.

In the above-mentioned embodiment, as an example, the sanitary napkin 1 is folded at three places to form a four-folded individual package. However, the present embodiment is not limited to this example. For example, by shifting the position of at least the second fold line FL2 in the width direction to the rear of the longitudinal direction _L among the first fold line _FL1 in the width direction and the second fold line _FL2 in the width direction, or the like, the third fold line in the width direction may be adjusted. _The area S3 and the _fourth area S4 in the width direction are integrated to form a residual area, and then the sanitary napkin 1 is folded in three at the first fold line _FL1 in the width direction and the second fold line _FL2 in the width direction. individual packaging. Moreover, for example, while adjusting the position of the longitudinal direction _L of the width direction 1st fold line FL1 - the width direction third fold line _FL3 , it is also possible to arrange a further one at the back of the length direction _L than the width direction third fold line FL3. The above-mentioned fold line _FL in the width direction increases the fold number of the individual package to five or more.

A plan view of another configuration example of such an individual package K is shown in FIG. 7 . The individual package K is formed by shifting the positions of both the first fold line FL1 in the width direction and the second fold line _FL2 in the width direction to the rear in the longitudinal direction _L , so that the _third area S3 in the width direction and the fourth area S3 in the width direction are shifted to the rear in the longitudinal direction L. The region S ₄ is integrated to form a stub region (here, the third region S ₃ in the width direction). In this case, as shown in FIG. 7, the individual package K has a longitudinal direction 1st folding line F _V1 , a longitudinal direction 2nd folding line F _V2 , a width direction 1st folding line _FL1 , and a width direction 2nd folding line _FL2 . The individual package K includes a first region S ₁ in the width direction, which is divided by the first fold line FL1 in the width direction and the second fold line _FL2 in the width direction, and is arranged from one side in the longitudinal direction _L to the other side, and the width direction. The second region S ₂ and the third region S ₃ in the width direction (also referred to as a residual region). The first fold line _FL1 in the width direction is, for example, arranged between the temperature-sensitive solution holding sheet 13 and the absorber 11, and the second fold line _FL2 in the width direction is arranged behind the sanitary napkin 1 (closer to the excretion port). contact area further back). The sanitary napkin 1 is folded at two places of the first folding line _FL1 in the width direction and the second folding line _FL2 in the width direction, and the individual packaging body K is made into three folds.

A perspective view of the folded state of such an individual package K is shown in FIG. 8 . As shown in FIG. 8, the sanitary napkin 1 is folded together with the packaging sheet 29 on the basis of the first fold line F _V1 in the longitudinal direction and the second fold line F _V2 in the longitudinal direction as the base axes, and then the first fold line in the width direction F _L1 and The second folding line _FL2 in the width direction is folded as a base axis, and the individual package K is formed. At this time, in the individual package K, in the thickness direction T, the widthwise _third region S3 is folded to the side of one side of the widthwise _second region S2 by the widthwise second folding line _FL2 , One fold line FL1 _folds the widthwise first region S1 toward _one side of the widthwise _second region S2. And the width direction _1st area|region S1 and the width direction _3rd area|region S3 are mutually joined by the adhesive part (Example: lead tape; not shown). In FIG. 8 , in the thickness direction T, the _third region S3 in the width direction is located on the side closer to the _second region S2 in the width direction than the _first region S1 in the width direction, but the _first region S1 in the width direction is also It can be located on the side closer to the _second region S2 in the width direction than the _third region S3 in the width direction. In this case, the end portion on the outer side in the longitudinal direction L of the widthwise first region S1 can be sandwiched between the widthwise third region S3 and the widthwise second region S2, and the fluid component of the temperature-sensitive solution can be prevented from volatilizing or flowing from the portion. And leak. Furthermore, the width direction _third region S3 can also be folded toward the other surface side of the width direction _second region S2 by the width direction second folding line _FL2 .

The above-described embodiment is, as an example, applicable to the sanitary napkin 1 in which the temperature-sensitive body 5 or the temperature-sensitive solution holding sheet 13 is provided in front of the longitudinal direction L of the absorption body 3 . However, the present embodiment is not limited to this example. For example, the sanitary napkin 1 in which the temperature-sensitive body 5 or the temperature-sensitive solution holding sheet 13 is provided behind the longitudinal direction L of the absorbent body 3 can be similarly applied only by reversing the front-to-back relationship.

As another embodiment, at least one of the widthwise _third region S3 and the widthwise _fourth region S4 defined by the widthwise second fold line _FL2 to the widthwise third fold line _FL3 may further have a physiological The area where the sanitary napkin 1 is used has other functional agents containing other fluid components. For example, in the sanitary napkin 1 , the temperature-sensing body 5 or the temperature-sensing solution holding sheet 13 can be provided not only in front of the longitudinal direction L of the absorbent body 3 , but also in the rear. At this time, the front end portion in the longitudinal direction _L of the widthwise third region S3 is folded at the position of the widthwise second folding line FL2, and the rear end portion is folded at the position of the widthwise third folding line _FL3 . Therefore, the front and rear ends of the _third area S3 in the width direction of the individual package K in the longitudinal direction L, even in the area including the sanitary napkin 1, hardly exist in the area that causes the fluid component to move to other areas. The gap can be regarded as almost closed. In addition, the front end in the longitudinal direction _L of the widthwise _fourth region S4 is folded at the position of the widthwise third folding line FL3, and the rear end is tied in the thickness direction T and sandwiched between the widthwise third folding line FL3. ₁ between the region S1 and the _third region S3 in the width direction. Therefore, the front and rear ends of the _fourth area S4 in the width direction of the individual package K, even in the area including the sanitary napkin 1, hardly exist that would cause the fluid component to move to the outside or other areas. The gap can be considered almost closed. That is, the area|region of the sanitary napkin 1 of the width direction _3rd area|region S3 and the width direction _4th area|region S4 is formed as a substantially closed space. Therefore, even if another functional layer is arranged in the area of the sanitary napkin 1 in at least one of the widthwise _third area S3 and the widthwise _fourth area S4, it is possible to suppress the volatilization or flow of the fluid component from the other functional layer and cause the Dissipated to the outside, or moved to other areas in the sanitary napkin 1 and adhered, or mixed with the functional components of the functional layer in other areas, resulting in a decrease in function, a change in function, and the like. That is, in the individual packaging body K of the sanitary napkin 1 provided with the temperature-sensitive solution holding sheet 13, other functional layers, etc., the effect of the functional ingredients can be maintained, and the fluid components of the functional layer can be suppressed from adhering to the sanitary napkin. Other areas of cotton 1.

In each of the aforementioned embodiments, ideally, both ends in the longitudinal direction L of the packaging sheet 29 are longer outside the longitudinal direction L than both ends in the longitudinal direction L of the sanitary napkin 1 . Therefore, the wrapping sheets 29 can be brought into close contact with each other on the outer side than the both ends of the sanitary napkin 1 . Therefore, for example, one of the end portions in the longitudinal direction L of the _first widthwise region S1 is the packaging sheets 29 in close contact with each other, and is sandwiched between the widthwise _second region S2 and the widthwise _fourth region S4 , therefore, the end portion in the longitudinal direction L of the _first region S1 in the width direction can be further closed. Thereby, even if the thermal solution holding sheet 13 is arranged in the area of the sanitary napkin ₁ in the first region S1 in the width direction, it is possible to further suppress the volatilization or flow of the fluid component from the thermal solution holding sheet 13 to be dissipated to the outside. , or move to other areas in the sanitary napkin 1 and attach.

As another embodiment, the end on the side of the _first region S1 in the width direction in the longitudinal direction L of the packaging sheet 29, that is, the end on the side of the temperature-sensitive solution holding sheet 13 may be sealed. For example, the ends may also be sealed by heat sealing, embossing sealing, or the like. Therefore, for example, _one of the ends in the longitudinal direction L of the first widthwise region S1 is sealed and held between the _second widthwise region S2 and the _fourth widthwise region S4 (or the remaining portion region). ), the end portion in the longitudinal direction L of the _first region S1 in the width direction can be further closed. Thereby, even if the thermal solution holding sheet 13 is arranged at least in the area of the sanitary napkin ₁ in the first region S1 in the width direction, it is possible to further suppress the volatilization or flow of the fluid component from the thermal solution holding sheet 13 to the outside. Dissipated, or moved to other areas in the sanitary napkin 1 and adhered.

In each of the above-mentioned embodiments, as an ideal aspect, in the individual package K, the first longitudinal direction region P1 and the longitudinal direction third folding line F _V1 and the longitudinal direction second folding line F _V2 are used as base axes, and the longitudinal direction _first region P1 and the longitudinal direction third The region _P3 is folded over the longitudinal _second region P2, whereby both ends in the width direction W are closed so that the fluid component does not move to the outside or other regions through the both ends in the width direction W. That is, both ends of the width direction W are not closed by a sealing process such as heat sealing. Therefore, the heat of the sealing process can prevent the fluid component from volatilizing or dissipating from the opening to the outside, or adhering to other areas in the sanitary napkin 1 . In addition, it is possible to suppress the generation of sound at the time of opening. In another embodiment, the both ends of the width direction W may be sealed by heat sealing or the like.

In each of the above-described embodiments, as an ideal aspect, in the individual package K, the temperature-sensitive solution holding sheet 13 is formed in the first region S1 in the width direction, which is closer to the front or rear of the longitudinal direction L than the absorber ₁₁ . The area of the sanitary napkin 1 can effectively exert the function of the warm-sensing solution on the abdomen or back. Also, even in this case, the individual package K is located in the absorber 11 where the excretion opening abutting region is located, that is, the second widthwise region S2 or the _third widthwise region S3 (remaining portion region) and the widthwise second region S2 Since the regions S1 are folded, the fluid component of the temperature-sensitive solution holding sheet ₁₃ in the _first region S1 in the width direction can be suppressed from flowing toward the _second region S2 in the width direction or the _third region S3 in the width direction, and the direction of the width direction. The excretion port abutting region in the _fourth region S4 and the like (residual portion region) moves and adheres.

In each of the above-described embodiments, as an ideal aspect, in the individual package K, the temperature-sensitive solution holding sheet 13 has a sheet shape, that is, it is different from the liquid-permeable sheet 7, the liquid-impermeable sheet 9, and the like. way to form. Therefore, the amount of the fluid component, the region or position of the temperature-sensitive solution holding sheet 13, and the like can be formed more accurately. Thereby, the effect of the temperature-sensitive solution holding sheet 13 can be more reliably maintained, and the fluid component of the temperature-sensitive solution holding sheet 13 can be more reliably prevented from moving and adhering to other areas of the sanitary napkin 1 .

In each of the aforementioned embodiments, as an ideal aspect, in the individual package K, the packaging sheet 29 is liquid-impermeable. Therefore, it is possible to further suppress volatilization or flow of the fluid component from the temperature-sensing solution holding sheet 13 , passing through the packaging sheet 29 and dissipating to the outside, or moving and attaching to other areas in the sanitary napkin 1 . That is, in the individual package K of the sanitary napkin 1 provided with the warm solution holding sheet 13, the effect of the functional component can be maintained, and the fluid component of the warm solution holding sheet 13 can be further suppressed from adhering to the sanitary napkin. Other areas of cotton 1.

In each of the aforementioned embodiments, the functional ingredient contained in the functional agent is a temperature-sensing agent. However, the present invention is not limited to this example. If at least one of the functional ingredient and the solvent ingredient contained in the functional agent contains a lipophilic ingredient, the type of functional ingredient may also be other types, such as cooling agent, exothermic agent. Wait. In the case of using a cooling agent, the functional layer has, for example, a cooling solution containing a cooling agent and a solvent component. When a heat generating agent is used, the functional layer has, for example, a heat generating solution containing a heat generating agent and a solvent component.

(Materials of absorbent articles, etc.) Next, each material and the like of the absorbent article related to each of the above-described embodiments will be described.

The functional layer of each of the foregoing embodiments has a functional agent, which includes a functional component for activating the TRP channel and a solvent component.

For example, a temperature-sensing solution includes: a temperature-sensing agent that activates TRP channels; and a vehicle. The temperature-sensing agent is not particularly limited as long as it can activate TRP channels, and examples include agonists for TRPV1 receptors, agonists for TRPV3 receptors, and the like, ideally agonists for TRPV1 agent. This is because the activation temperature threshold of the TRPV1 receptor system exceeds the higher temperature of 43°C, which can impart a higher thermal sensation to the wearer.

From the viewpoint of the safety of the wearer, the aforementioned warming agent is preferably a compound derived from a plant. Examples of the warming agent include capsaicin, capsaicin, and capsaicinoids (dihydrocapsaicin, proto-dihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, noniquat, etc.) ; Capsanthin; Benzyl Nicotinate; Nicotinic Acid-β-Butoxyethyl Ester; N-Acetyl Glycerophosphate; Vanillyl Amide Nonanoate; Extract; vanillyl ether of nonanoic acid; vanillyl alcohol alkyl ether derivatives (eg: vanillyl butyl ether, vanillyl alcohol ethyl ether, vanillyl amyl ether, vanillyl hexyl ether); isovanillyl alcohol alkyl ether; Ethyl vanillyl alcohol alkyl ether; veratrol derivatives; substituted benzyl alcohol derivatives; substituted benzyl alcohol alkyl ethers; vanilla extract propylene glycol acetaldehyde; ethyl vanillyl alcohol propylene glycol acetaldehyde; ginger extract Ginger oil; gingerol; gingerol; hesperidin; and pyrrolidone carboxylic acid; and any combination of these.

From the viewpoint that the wearer is less likely to feel pain and itching, the aforementioned warming agent is not capsaicin, and vanillyl alcohol alkyl ether derivatives are most desirable, such as vanillyl alcohol ethyl ether, vanillyl butyl ether, vanilla More preferred are methylamyl ether, vanillyl hexyl ether, ginger extract, ginger oil, gingerol, and gingerone, and any combination of these.

For example, a cooling sensation solution includes a cooling agent that activates TRP channels; and a vehicle. The cooling agent is not particularly limited as long as it can activate the TRP channel, for example, an agonist for the TRPM8 receptor, an agonist for the TRPA1 receptor, etc., and an agonist for TRPM8 is ideal . This is so as not to impart excessive cooling to the wearer.

Examples of the cooling sensation include: menthol (for example, 1-menthol) and derivatives thereof (for example, menthyl glyceryl ether such as menthyl lactate, 1-menthyl glyceryl ether, etc.); methyl salicylate Esters; camphor; essential oils derived from plants (eg: peppermint, eucalyptus), etc.

The solvent is not particularly limited as long as it can contain the warming agent and the cooling agent, and examples thereof include a lipophilic solvent and a hydrophilic solvent. The aforementioned solvent can dissolve, disperse, or the like, for example, the aforementioned warming agent and the aforementioned cooling agent. Examples of the lipophilic solvent include natural oils and fats (eg, fatty acid esters such as triglycerides, coconut oil, linseed oil, etc.), hydrocarbons (eg, paraffin waxes such as mobile paraffin), and the like. As said hydrophilic solvent, water and alcohol are mentioned. Examples of the alcohols include lower alcohols such as methanol, ethanol, ethylene glycol, and glycerin, and higher alcohols such as octanol, lauryl alcohol, and myristyl alcohol.

As the solvent, fats and oils (lipophilic solvents) or alcohols (hydrophilic solvents) are preferred from the viewpoint of easy control of volatility, and particularly reduction in volatility. Moreover, in an absorbent article, it is preferable that the said solvent is a lipophilic solvent from a viewpoint that it is hard to inhibit absorbency.

The warm-sensing solution or the cooling-sensing solution preferably contains 0.0001 to 5.0 mass % of the aforementioned warming or cooling agent, more preferably 0.0005 to 3.0 mass %, still more preferably 0.1 to 1.0 mass %, and most preferably 0.3-0.7 mass % is contained.
