Japanese Patent Publication No. 2004-528090

The functional agent contains a functional component and a solvent component, such as a warm feeling component and a cold feeling component. These functional components and solvent components may contain a fluid component that can move from a location to a gas or liquid.

Then, a case will be considered in which an absorbent article provided with a functional layer having a functional agent containing a fluid component is packaged in a packaging sheet to form an individual package. In this case, in the packaging sheet of the individual packaged body, the fluid component may volatilize or flow from the region where the functional layer of the absorbent article is disposed, and thereafter, there is a fear that it adheres to other inappropriate regions. For example, when the functional layer is disposed at the end portion in the longitudinal direction of the absorbent article, there is a fear that the fluid component of the functional layer volatilizes or flows, and then adheres to the excrement contact region. In such a case, since the contact area of the excretion opening contacts the excretion opening which is sensitive to drugs or the like, there is a concern that the wearer may feel discomfort or the like depending on the type of the fluid component. Even so, it is difficult to separate the inside of the packaging sheet of an individual package by a heat seal or an emboss seal, so that when the fluid component of the functional layer is volatilized or moved, it does not move to an inappropriate area. Moreover, if the amount of the fluid component is reduced or the area of the functional layer is made small, the effect of the functional component may be reduced.

Accordingly, an object of the present invention is to prevent the fluid component of the functional layer from adhering to other areas of the absorbent article, while maintaining the effect of the functional component of the functional layer in the individual package of the absorbent article having the functional layer. It is possible to provide individual packages.

The individual packaged body in the present invention has a length direction, a width direction and a thickness direction, and is provided with a packaging sheet and an absorbent article, and the absorbent article is placed on the packaging sheet and folded together with the packaging sheet. An individually packaged package that is individually opened and packaged, wherein the individual package is in a deployed state, extending along the width direction, and extending along a width direction from one side to the other side of the first cut line parallel to each other at predetermined intervals, and A first region, a second region, and a residual region, which have a second cut line, and are divided into the first cut line and the second cut line, and are lined from the one side in the longitudinal direction to the other side, and the first area And a functional layer having a predetermined function in a region of the absorbent article at at least one side of the second region, wherein the functional layer has a functional agent containing a fluid component. In the individual package, both ends of the width direction are sealed or folded open, and the second remainder region in the second cut line is on the side of one or the other side of the second region. The individual packaged body which is folded open and the first area in the first cut line is folded open to the side of the one side of the second area.

According to the present invention, in an individual package of an absorbent article having a functional layer, while maintaining the effect of the functional component of the functional layer, it is possible to suppress the fluid component of the functional layer from adhering to other areas of the absorbent article.

The longitudinal first region P ₁ and the longitudinal third region P ₃ overlap the longitudinal second region P ₂ . That is, both ends of the width direction W are folded.

And, as shown in Fig. 4, the menstrual pad 1, before use, together with the packaging sheet 29, the first longitudinal line F _V1 and the second longitudinal line F _V2 , Each of the individual packages (K) of the physiological pad 1 is opened by folding each with a first axis of the width direction F _L1 , a second direction of the width F _L2 , and a third direction of the width direction F _L3 . ). At this time, in the individual package body K, in the thickness direction T, the first region S ₁ in the width direction is between the second region S ₂ in the width direction and the fourth region S _{4 in} the width direction. The fourth area S ₄ in the width direction is positioned between the third area S ₃ in the width direction and the first area S _{1 in} the width direction. Then, the first region S ₁ in the width direction and the fourth region S _{4 in} the width direction are joined to each other by an adhesive portion (not shown).

Further, in the present embodiment, the first cut line F _{L1 in} the width direction is in a developed state of the menstrual pad 1 and the packaging sheet 29 in the warm feeling solution holding sheet 13 and in the thickness direction T They are arranged to overlap. The longitudinal 1st cutting line F _V1 and the longitudinal 2nd cutting line F _V2 are in the unfolded state of the menstrual pad 1 and the packaging sheet 29 in the absorber 11 and the thickness direction T Although it does not overlap, it is arrange | positioned so that a warm feeling solution holding sheet 13 and a thickness direction T may overlap.

Moreover, the pad 1 for menstruation is provided with the sealing part 25 and the embossing part 27. The sealing portion 25 bonds and seals the liquid-permeable sheet 7 and the liquid-impermeable sheet 9 at their outer edges by methods known in the art, such as heat seals. In the present embodiment, the embossed portion 27 is formed so as to surround at least the excretion opening abutting area, and preferably further outside the longitudinal direction L. However, the contact area of the excretion opening may be changed depending on the shape of the absorbent body 11, for example, in the longitudinal direction L, approximately the range of the flap portion 23 or the center 1/3 of the absorbent body 11, In the width direction W, it is an area defined by the range of the center 1/3 of the absorber 11.

In the physiological pad 1, the non-skin side of the liquid-permeable sheet 7 and the surface of the absorber 11 and the skin-side of the warm-feel solution holding sheet 13 are bonded with an adhesive (for example, hot melt adhesive) or the like. , The surface on the non-skin side of the absorber 11 and the shape-retaining member 15 and the surface on the skin side of the liquid-impermeable sheet 9 are bonded with an adhesive or the like. In addition, the periphery of the surface of the liquid-permeable sheet 7 on the non-skin side and the periphery of the surface of the liquid-impermeable sheet 9 on the skin side are joined by an adhesive or the like. The surface on the non-skin side of the warm-feel solution holding sheet 13 and the surface on the skin side of the shape-retaining member 15 are joined by an adhesive or the like.

Next, a method of using the physiological pad 1 according to the present embodiment will be described.

As shown in FIG. 3, when the wearer A wears the menstrual pad 1, first, an adhesive portion (not shown) between the first region S ₁ in the width direction and the fourth region S _{4 in} the width direction Is not released), and the individual package K is put into a deployed state (Fig. 1). Subsequently, since the absorbent body 3 has the same shape as a normal physiological pad, so that the absorbent body 11 of the absorbent body 3 corresponds to an abutment contact area (not shown) of the wearer A, While removing the packaging sheet 29, the menstrual pad 1 is fixed to the garment 19 (eg, underpants). Thereby, the physiological pad 1 is fixed to the garment 19 so that the warm body 5, in particular the warm solution holding sheet 13 corresponds to the lower abdomen of the wearer A. In addition, the physiological pad 1 is used in a state where the skin-contacting surface of the warm body 5 is in contact with the skin of the lower abdomen of the wearer A.

In other words, in the pad 1 for menstruation, the absorbent body 3 is disposed on the wearer 19 so that the excrement abutment area (not shown) of the absorbent body 11 abuts the excrement abutment area of the wearer A. When it is, the warm feeling solution holding sheet 13 has a shape such that it is disposed at a position corresponding to the lower abdomen of the wearer A. Accordingly, the distance between the contact area (not shown) of the absorbent body 11 of the absorbent body 3 and the warm feeling solution holding sheet 13 of the warm body 5 is the distance between the wearer's excretory port and the lower abdomen (on the skin surface). Of distance).

In the present embodiment, the warming solution (functional agent) of the warming solution holding sheet 13 includes a warming agent (warm component) and a solvent (solvent component) that activate the TRP channel. Therefore, when the sanitary pad 1 is fixed to the garment 19 and used, the warming solution contained in the warming solution holding sheet 13 penetrates through the liquid permeable sheet 7 and the skin of the wearer A , And effectively activates the TRP channel of the warming agent contact portion of the skin of the wearer A, where the warming agent is in contact, to effectively impart warmth to the wearer's lower abdomen.

By applying warmth to the lower abdomen of the wearer, the TRP channel of the warming agent contact portion of the skin of the lower abdomen of the wearer that is in contact with the warming agent is activated. It can be expected to increase the temperature of the contact portion of the skin with the warming agent. As a result, it is expected that the area close to the wearer's womb is warmed to release prostaglandin, a pain substance, to relieve the wearer's dysmenorrhea. In addition, it is expected to reduce wearer's premenstrual syndrome, cold constitution, and menopausal disorder by warming the area close to the wearer's womb. In addition, by promoting blood circulation (accelerating the flow of lymph), waste discharge and coldness are improved, fat burning is improved, and immunity is improved.

Next, the packaging method of the individual package body K concerning this embodiment is demonstrated.

5 and 6 are schematic diagrams showing the packaging method of the individual packaged body K according to the present embodiment. First, as shown in Fig. 5 (a), the menstrual pad 1 is placed on the packaging sheet 29. Subsequently, as shown in FIG. 5 (b), for the menstrual pad 1 and the packaging sheet 29, the longitudinal first cutout line F _V1 is used as the main axis, and the longitudinal first region P ₁ Is folded on the second region P _{2 in} the longitudinal direction. Subsequently, as shown in FIG. 6 (a), the longitudinal third area P ₃ is folded on the longitudinal second area P ₂ with the longitudinal second cut line F _V2 as a main axis. Grow. However, the order of folding the first region P _{1 in the} longitudinal direction and the third region P _{3 in} the longitudinal direction may be reversed. Subsequently, as shown in FIG. 6 (b), the first area S ₁ in the width direction is folded on the second area S _{2 in the} width direction with the first axis F _L1 in the width direction as a main axis. At the same time, the widthwise fourth area S ₄ is folded and opened on the widthwise third area S _{3 using} the widthwise third cut line F _L3 as a main axis. Then, as shown in FIG. 6 (c), the first region S ₁ in the width direction is folded over the fourth region S _{4 in the} width direction, using the second cut line F _L2 in the width direction as a main axis. Open it. However, the fourth area S ₄ in the width direction may be folded and opened on the first area S _{1 in} the width direction. Thereby, the individual package body K of the physiological pad 1 in which the physiological pad 1 is packaged on the packaging sheet 29 is formed.

Here, in the case of forming an individual packaged body by packaging a menstrual pad having a warmth solution containing a fluid component in a packaging sheet, in the packaging sheet of the individual packaged body, a warmth is sensed from the area where the warmth solution of the menstrual pad is placed. There is a concern that the fluid component of the solution may volatilize or flow, and then adhere to other inappropriate areas in the sanitary pad. For example, when a warm feeling solution is disposed at the end portion in the longitudinal direction of the sanitary pad, the fluid component of the warm feeling solution may volatilize or flow, and thereafter, there is a fear that it adheres to the excrement contact area. In such a case, since the contact area of the excretion opening contacts the excretion opening which is sensitive to drugs or the like, there is a concern that the wearer may feel discomfort or the like depending on the type of the fluid component. Even so, it is difficult to partially separate the inside of the packaging sheet of the individual packages by heat seals or emboss seals so that when the fluid component of the warming solution is volatilized or moved, it does not migrate to an inappropriate area. Moreover, if the amount of the fluid component is reduced or the area of the warming solution is made small, the effect of the warming component may be reduced.

Thus, in the individual package body K according to the present embodiment, the width direction first region S ₁ and the width direction divided by the width direction first cut line F _L1 to the width direction second cut line F _L2 . In a region of the menstrual pad 1 on at least one side of the second region S ₂ , a warm-feel solution holding sheet 13 containing a fluid component is provided. In this case, the end portions in the width direction, the width direction of the longitudinal direction (L) in the first region (S ₁₎ a second area (S ₂₎ side, and folded at the position of the width direction of the first jeolseon (F _L1). Therefore, the end portion of the width direction second region S _{2 in} the longitudinal direction L of the first region S _{1 in} the width direction of the individual package body K has a gap in which fluid components can move to different regions. It can be considered that there is almost no including the inside of the dragon pad 1, and it is occluded to some extent. The width direction of the second area (S ₂₎ end of the side width direction of the first region (S ₁₎ in the longitudinal direction (L) of the can, the folded in position in the width direction of the first jeolseon (F _L1), the width The end portion on the direction third region S ₃ (remaining region) side is folded at the position of the second cutting line F _{L2 in} the width direction. Therefore, the front and rear ends of the longitudinal direction L of the second region S _{2 in} the width direction of the individual package body K have gaps in which the fluid components can be moved to different regions in the physiological pad 1. Almost none, including, it can be considered that it is mostly occluded. That is, the area of the width direction of the first region (S ₁₎ and width direction of the second area (S ₂₎ sanitary pad (1) is in, and both are substantially in a closed space.

For this reason, even if a warm feeling solution holding sheet 13 is disposed in the area of the physiological pad 1 in at least one of the width direction first area S ₁ and the width direction second area S ₂ , these warm feelings The fluid component volatilizes or flows from the solution holding sheet 13 and can be prevented from moving and adhering to other areas in the physiological pad 1. That is, in the individual package of the menstrual pad 1 provided with the warm feeling solution holding sheet 13, while maintaining the effect of the warm feeling component, the fluid component of the warm feeling solution holding sheet 13 is the menstrual pad 1 Can be prevented from adhering to other areas.

As a preferred aspect in the above embodiment, in the individual package body K, in the thickness direction T, the first region S ₁ in the width direction is the second region S _{2 in} the width direction and the remaining region (eg, width) It is located between the third area S _{3 in the} direction or the fourth area S _{4 in} the width direction. At this time, the end portion on the side opposite to the width direction second region S _{2 in} the longitudinal direction L in the width direction first region S ₁ is the width direction second region S in the thickness direction T ₂ ) is sandwiched between the remainder region, and is in an obstructive state, and the end portion on the second region S ₂ side in the width direction is folded at the position of the first cut line. Therefore, both ends of the longitudinal direction L of the first region S _{1 in} the width direction of the individual package body K include a gap within the physiological pad 1 in which a fluid component can move to the outside or another region. Almost none, most likely occluded. That is, the area of the physiological pad _{1 in} the first area S _{1 in} the width direction is a more closed space. For this reason, even if the warm feeling solution holding sheet 13 is arranged in the first region S _{1 in} the width direction, the fluid components volatilize or flow from these warm feeling solution holding sheets 13 to scatter outside, or the physiological pad ( 1) It is possible to further suppress the movement to other areas within and attachment. That is, in the individual package of the menstrual pad 1 provided with the warm feeling solution holding sheet 13, while maintaining the effect of the functional component, the fluid component of the warm feeling solution holding sheet 13 is the menstrual pad 1 Can be prevented from adhering to other areas.

In the above-described embodiment, as a preferred aspect, the amount of the warming solution in the second region S _{2 in} the width direction close to the abutment contact region is the width direction of the first region S ₁ far from the abutment contact region. Less than the amount of warming solution. In order to avoid the influence to the excrement port, it is a viewpoint to more reliably suppress the migration of the fluid component to the excrement contact area.

Further, in the embodiment, as an example, a solution ongam the holding sheet 13 is disposed on a width direction of the first region (S ₁₎ and width direction of the second area (S _2). However, the present embodiment is not limited to this example, and the warm feeling solution holding sheet 13 may be disposed only in one of the first region S ₁ and the second region S _{2 in} the width direction. .

In the above embodiment, as an example, the menstrual pad 1 is folded in three places and is an individual package body folded in four. However, the present embodiment is not limited to this example. For example, by moving the positions of at least the widthwise second cutting lines F _{L2 of} the widthwise first cutting lines F _L1 and the widthwise second cutting lines F _L2 to the back of the longitudinal direction L, etc. The third area S _{3 in the} direction and the fourth area S _{4 in} the width direction are combined to form a residual area, and the first pad line F _L1 for the menstrual pad 1 and the second line section F for the width direction F _L2 ) may be folded in two places, or may be individually folded in three. In addition, for example, a width smaller than the longitudinal direction of the first jeolseon (F _L1) ~ widthwise third jeolseon (F _L3), widthwise third jeolseon (F _L3) by adjusting the position in the longitudinal direction (L) of ( One or more widthwise cut lines F _L may be disposed on the back of _L ) to increase the number of folds of the individual packages to 5 or more.

7 shows a plan view of another configuration example of such individual package K. The individual package body K moves the positions of both of the first and second transverse lines F _L1 and F _L2 to the rear of the longitudinal direction L, thereby extending the third area S in the transverse direction S ₃ ) and the fourth area S ₄ in the width direction are integrated to be the remaining area (here, the third area S ₃ in the width direction). In this case, the individual package bodies K are, as shown in FIG. 7, the first longitudinal line F _V1 and the second longitudinal line F _V2 , and the first longitudinal line F _L1 and the width. It has a direction second cut line F _L2 . The individual package body K is divided into a first section line F _{L1 in the} width direction and a second section line F _L2 in the width direction, and a first area in the width direction lined from one side to the other in the longitudinal direction L ( S ₁ ), a second region S _{2 in the} width direction, and a third region S _{3 in} the width direction (also referred to as a residual region). However, the 1st cut line F _{L1 in a} width direction is arrange | positioned, for example, between the warm feeling solution holding sheet 13 and the absorber 11, and the 2nd cut line width F _L2 is a pad for menstruation ( It is arranged at the back of 1) (behind the abutment contact area). The menstrual pad 1 is folded in two places in the width direction first cut line F _L1 and the width direction second cut line F _L2 , and is set as an individual package K folded in three.

8 is a perspective view of the folded state of the individual package body K. As shown in Fig. 8, the menstrual pad 1 is folded and opened with the packaging sheet 29 as the main axis of the first longitudinal line F _V1 and the second longitudinal line F _V2 , respectively. And, the width direction first cut line (F _L1 ) and the width direction second cut line (F _L2 ) are folded and opened, respectively, as a main axis to form an individual package body (K). At this time, in the individual package body K, in the thickness direction T, in the width direction second cut line F _L2 , the width direction third area S ₃ is one of the width direction second areas S ₂ Folded to the side of the surface, the first region S ₁ in the width direction is folded to the side of one side of the second region S ₂ in the width direction in the first cut line F _L1 in the width direction. Then, the first region S ₁ in the width direction and the third region S _{3 in} the width direction are joined to each other by an adhesive portion (eg, a lead tape; not shown). However, in FIG. 8, in the thickness direction T, the third area S ₃ in the width direction is located on the side of the second area S _{2 in} the width direction than the first area S _{1 in the} width direction. The direction first region S ₁ may be located closer to the width direction second region S ₂ than the width direction third region S ₃ . In that case, the end portion outside the longitudinal direction L of the first region S ₁ in the width direction can be fitted into the third region S ₃ in the width direction and the second region S _{2 in} the width direction, and there is a sense of warmth from there. It is possible to prevent the fluid component of the solution from volatilizing or flowing and leaking. In addition, in the width direction second cut line F _L2 , the width direction third area S ₃ may be folded to the side of the other side of the width direction second area S ₂ .

As an example, the above-described embodiment is applied to the physiological pad 1 in which the warm body 5 or the warm solution holding sheet 13 is provided in the longitudinal direction L in the absorbent body 3. However, the present embodiment is not limited to this example. For example, the relationship between the front and back is also reversed for the physiological pad 1 provided in the longitudinal direction L in the absorbent body 3 in which the warm body 5 or the warm solution holding sheet 13 is provided. It can apply just likewise.

As another embodiment, further, the width direction 3rd area | region S ₃ and the width direction 4th area | region S ₄ divided by the width direction 2nd cutting line F _L2 -width direction 3rd cutting line F _L3 Other functional agents containing different fluid components may be provided in the region of the physiological pad 1 on at least one of. For example, in the pad 1 for menstruation, not only the warm body 5 or the warm solution holding sheet 13 is provided on the front side in the longitudinal direction L in the absorbent body 3, It may be installed at the rear.

At this time, the front end of the longitudinal direction L in the third region S ₃ in the width direction is folded at the position of the second cutting line F _L2 in the width direction, and the rear end portion is made of the width direction agent. 3 Folded at the position of the cutting line F _L3 . Therefore, the front end and the rear end of the longitudinal direction L of the third region S _{3 in} the width direction of the individual package body K have gaps in which the fluid components can be moved to different regions in the physiological pad 1. Almost none, including, it can be considered that it is mostly occluded. Moreover, the front end of the longitudinal direction L in the fourth area S ₄ in the width direction is folded at the position of the third cutting line F _{L3 in} the width direction, and the rear end is in the thickness direction T Therefore, it is sandwiched between the first region S ₁ in the width direction and the third region S _{3 in} the width direction. Therefore, the front and rear ends of the fourth region S _{4 in} the width direction of the individual package body K have almost no gap in which the fluid component can be moved to the outside or to other regions, including within the physiological pad 1. No, it can be said to be mostly occluded. That is, the area of the physiological pad 1 in the width direction third area S ₃ and the width direction fourth area S ₄ is generally a closed space.

Therefore, even if another functional layer is disposed in the area of the physiological pad 1 in at least one of the third area S _{3 in the} width direction and the fourth area S _{4 in} the width direction, fluid from other functional layers is obtained. It is possible to suppress the component from volatilizing or flowing and scattering to the outside, moving to another region in the physiological pad 1, or mixing with the functional component of the functional layer of the other region to cause deterioration or functional change. . That is, in the individual package (K) of the menstrual pad (1) having a warm feeling solution holding sheet (13) or other functional layer, while maintaining the effect of the functional component, the fluid component of the functional layer is a physiological pad ( It is possible to suppress adhesion to other areas of 1).

As a preferred aspect in each of the above embodiments, both ends of the longitudinal direction L in the packaging sheet 29 are in the longitudinal direction L than both ends of the longitudinal direction L in the sanitary pad 1. Long outward

Therefore, the packaging sheets 29 can be in close contact with each other outside the both ends of the sanitary pad 1. Therefore, for example, one end of the longitudinal direction L in the width direction first region S ₁ is in close contact with the second direction region S ₂ while the packaging sheets 29 are in close contact with each other. width direction of 4, so this is caught between the area (S _4), the transverse direction it is possible to clogging than the end portion in the longitudinal direction (L) of the first region (S _1). Thereby, the fluid component volatilizes or flows from the warm feeling solution holding sheet 13 even if the warm feeling solution holding sheet 13 is arranged in the area of the menstrual pad _{1 in} the first region S ₁ in the width direction. By doing so, it can be further suppressed to stick to the outside or move to another area in the physiological pad 1 to adhere.

As another embodiment, the end portion on the side of the first region S _{1 in} the width direction of the longitudinal direction L in the packaging sheet 29, that is, the end portion on the side with the warm-feel solution holding sheet 13 may be sealed. . For example, the end portion may be sealed with a heat seal, emboss seal, or the like. Therefore, for example, one end of the longitudinal direction L in the width direction first region S ₁ is sealed, while being sealed, the width direction second region S ₂ and the width direction fourth region S ₄ ) (or the remaining region) is sandwiched between the ends of the longitudinal direction L of the first region S ₁ in the width direction. Thereby, even if the warm feeling solution holding sheet 13 is disposed in the area of the menstrual pad 1 in at least the first region S ₁ in the width direction, the fluid component volatilizes from the warm feeling solution holding sheet 13 or It can be further suppressed that it flows and diffuses to the outside or moves to another area in the pad for physiology 1.

As a preferred aspect in each of the above-described embodiments, in the individual package body K, the longitudinal first cut line F _V1 and the longitudinal second cut line F _V2 are used as the main axis, and the longitudinal first area P ₁ ) And the longitudinal third area P ₃ are folded on the longitudinal second area P ₂ so that the fluid component cannot move to the outside or other areas through both ends of the width direction W. Both ends of the direction W are closed. That is, both ends of the width direction W are not blocked by a sealing process by a heat seal or the like. Therefore, it is possible to suppress the fluid component from volatilizing due to the heat of the sealing process and scattering from the opening to the outside or adhering to other areas in the physiological pad 1. Moreover, the generation of sound at the time of opening can be suppressed. In another embodiment, both ends of the width direction W may be sealed by a heat seal or the like.

As a preferable aspect in each of the above-described embodiments, in the individual package body K, the warm feeling solution holding sheet 13 has a width direction first region S _{1 in the} longitudinal direction L or in front of the absorber 11. Since it is formed in the region of the physiological pad 1 in), it is possible to more effectively exhibit the function of the warming solution against the abdomen or the back. In addition, even in that case, the individual package body K is the absorber 11 in which the excrement abutting area is located, that is, the second area S _{2 in the} width direction or the third area S _{3 in} the width direction (or the remaining area) ) and a width direction of the so folded between the first region (S _1), width direction of the first region (S _1), the fluid component is width direction of the second region of ongam solution holding sheet 13 in the (S ₂₎ or width It can be suppressed to move and adhere to the excretion contact area in the third area S _{3 in the} direction or the fourth area S _{4 in} the width direction (or the remaining area).

As a preferred aspect in each of the above embodiments, in the individual package K, the warm-feel solution holding sheet 13 has a sheet shape, that is, separate from the liquid-permeable sheet 7 or the liquid-impermeable sheet 9. Is formed. Therefore, the amount of the fluid component and the region or position of the warm-feel solution holding sheet 13 can be formed more accurately. Thereby, while maintaining the effect of the warm feeling solution holding sheet 13 more accurately, it is possible to more accurately suppress the fluid components of the warm feeling solution holding sheet 13 from moving and adhering to other areas of the physiological pad 1. have.

As a preferable aspect in each of the above-described embodiments, in the individual package body K, the packaging sheet 29 is non-permeable. Therefore, it is further suppressed that the fluid component volatilizes or flows from the warm-feel solution holding sheet 13 to escape the packaging sheet 29, scatter to the outside, or move to another area in the physiological pad 1 to adhere. Can be. That is, in the individual package K of the menstrual pad 1 provided with the warm solution holding sheet 13, while maintaining the effect of the functional component, the fluid component of the warm solution holding sheet 13 is the menstrual pad It is possible to further suppress adhesion to other areas of (1).
