At least the following points will become apparent from the description of this specification and the accompanying drawings.
An individual package of a pant-type absorbent article comprising a pant-type absorbent article having a waist opening and a pair of leg openings, and having mutually perpendicular vertical, horizontal, and front-to-rear directions when unfolded, and a packaging material for packaging one of the pant-type absorbent articles, wherein the pant-type absorbent article has a volatile substance on the inside, the oxygen permeability of the packaging material is 200 cc/ ^m2 /day/atm or less, and in the packaged state, the pant-type absorbent article is folded at a folding portion along the vertical direction or the left-to-right direction, and the packaging material has at least one folding portion, and the folding portion is along the vertical direction of the pant-type absorbent article.

This type of individually packaged pant-type absorbent article makes the pant-type absorbent article a more compact individually packaged pant-type absorbent article, while at least one of the leg openings can be provided on the folded side of the packaging material, thereby reducing the risk of volatile substances provided in the pant-type absorbent article leaking out of the packaging material through the leg openings.

In the individually packaged pants-type absorbent article, in the packaged state, the packaging material has end joints that join the packaging materials together, the end joints are aligned along the left-right direction of the pants-type absorbent article, and have one-side end joints and other-side end joints at one end and the other end of the packaging material in the up-down direction of the pants-type absorbent article, respectively, and the joint strength of the one-side end joint is higher than the joint strength of the other-side end joint, and it is desirable that the waist opening is provided on one side in the up-down direction.

In this type of individually packaged pants-type absorbent article, the bonding strength of the joint at one end is higher than the bonding strength of the joint at the other end, which reduces the risk of volatile substances leaking out of the packaging material from the one end, compared to when the bonding strength of the joint at one end is lower than the bonding strength of the joint at the other end.

An individual package of a pant-type absorbent article comprising a pant-type absorbent article having a waist opening and a pair of leg openings, and having mutually perpendicular top-bottom, left-right, and front-to-back directions when unfolded, and a packaging material for packaging one of the pant-type absorbent articles, wherein the pant-type absorbent article has a volatile substance on the inside, the oxygen permeability of the packaging material is 200 cc/ ^m2 /day/atm or less, and in the packaged state, the pant-type absorbent article is folded at a folding portion along the top-bottom direction or the left-right direction, and the packaging material has at least one folding portion, the folding portion is along the left-right direction of the pant-type absorbent article, and the folding portion faces the waist opening.

This type of individually packaged pant-type absorbent article makes the pant-type absorbent article a more compact individually packaged pant-type absorbent article, while at the same time, by facing the waist opening to the folded side of the packaging material, it is possible to reduce the risk of volatile substances provided in the pant-type absorbent article leaking out of the packaging material through the leg openings.

In such an individually packaged pant-type absorbent article, the pant-type absorbent article is folded at upper and lower folds along the left-right direction, and the volatile substance is desirably provided on the crotch side of the folds in the up-down direction of the pant-type absorbent article in its unfolded and natural state.

In this type of individually packaged pants-type absorbent article, the folded parts of the packaging material prevent the leakage of volatile substances to the outside of the packaging material through the leg openings or waist openings, while the volatile substances provided on the crotch side in the vertical direction from the upper and lower folded parts of the pants-type absorbent article are sandwiched between the folded parts and the crotch part, further reducing the risk of volatile substances leaking out of the packaging material.

In the individual package of such a pant-type absorbent article, the pant-type absorbent article includes an absorbent body, and the pant-type absorbent article is folded at left and right folding parts along the up-down direction, and in the pant-type absorbent article in an unfolded and natural state, it is desirable that the left and right folding parts are provided outside the absorbent body in the left-right direction, and the volatile substance is provided inside the left and right folding parts in the left-right direction.

In this type of individually packaged pants-type absorbent article, the folded parts of the packaging material prevent the volatile substance from leaking out of the packaging material through the leg openings or waist openings, while the left and right folded parts narrow the path through which the volatile substance located inside the left and right folded parts of the pants-type absorbent article leaks out of the leg openings, further reducing the risk of the volatile substance leaking out of the packaging material.

In the individual package of such pants-type absorbent article, in the packaged state, the packaging material has a direction along the folded portion, an orthogonal direction perpendicular to the direction along the folded portion, and a thickness direction perpendicular to the direction along the folded portion and the orthogonal direction, the packaging material has a joint that joins the packaging materials together, the joint is along the orthogonal direction, and it is desirable that when the pants-type absorbent article is placed at a certain position within the packaging material, the longest distance between the folded portion and the pants-type absorbent article is shorter than the longest distance between the joint and the pants-type absorbent article.

With such an individually packaged pant-type absorbent article, in the packaged state, the space between the folded portion and the pant-type absorbent article can be narrower than when the longest distance between the folded portion and the pant-type absorbent article is longer than the longest distance between the joint and the pant-type absorbent article, which reduces the amount of volatile substances that leak into the packaging material through the leg openings or waist openings, making it easier to further reduce the amount that leaks out of the packaging material.

In the individually packaged pants-type absorbent article, in the packaged state, the packaging material has a direction along the fold, an orthogonal direction perpendicular to the direction along the fold, and a thickness direction perpendicular to the direction along the fold and the orthogonal direction, the packaging material has joints that join the packaging materials together, the joints having an end joint along the orthogonal direction and provided at an end of the packaging material, and an inner joint along the fold and provided inward from the fold in the orthogonal direction, and it is desirable that the joint strength of the inner joint is greater than the joint strength of the end joint.

With such individually packaged pants-type absorbent articles, the end joints, which have a lower joining strength, can be peeled off to make it easier to open the individually packaged pants-type absorbent article, while the inner joints, which have a higher joining strength, tend to maintain their joined state, making it easier to keep the packaging in a bag shape, and making it easier to carry or discard the pants-type absorbent article in the packaging after use.

In the individual package of such pants-type absorbent article, the pants-type absorbent article is folded at upper and lower folds along the left-right direction, and is also folded at left and right folds along the up-down direction, and in the packaged state, the joint has an inner joint that is provided along the fold and is located inside the fold in the perpendicular direction, and the inner joint is preferably provided at a position closer to the crotch portion than the waist opening in the front-rear direction of the pants-type absorbent article.

In such an individual package of pants-type absorbent articles, an absorbent body is generally provided in the crotch portion of the pants-type absorbent article, and since the crotch portion is more rigid than the portion where the waist opening is provided, providing the inner joint at a position closer to the crotch portion makes it easier to form the inner joint in a more stable state and makes it easier to increase the joining strength of the inner joint. In addition, since a waist opening can be provided on a surface of the individual package of pants-type absorbent article that does not have an inner joint in the thickness direction, the risk of volatile substances leaking out from the inner joint can be reduced.

In the individually packaged pant-type absorbent article, it is desirable that in the packaged state, the length from the upper and lower folds to the waist opening in the vertical direction of the pant-type absorbent article is equal to or greater than the length from the upper and lower folds to the end of the crotch portion.

In this type of individually packaged pants-type absorbent article, the upper and lower folds can be folded to cover a wider area of the leg openings on the waist opening side than the upper and lower folds, reducing the risk of volatile substances leaking out from the leg openings.

In the individually packaged pant-type absorbent article, it is desirable that in the packaged state, the length from the upper and lower folds to the end of the crotch portion in the vertical direction of the pant-type absorbent article is longer than the length from the upper and lower folds to the waist opening.

In this type of individually packaged pants-type absorbent article, the crotch portion covers the waist opening, and the waist opening can be sandwiched between the crotch portion and the packaging material, reducing the risk of volatile substances leaking out from the waist opening.

The package for the individual packaging of such pants-type absorbent articles has a bag body that contains the individual packaging of the pants-type absorbent article, and it is desirable that the oxygen permeability of the bag body is 200 cc/ ^m2 /day/atm or less.

This type of packaging for the individual wrapper of the pants-type absorbent article reduces the risk of the volatile substance provided in the pants-type absorbent article leaking outside the individual wrapper of the pants-type absorbent article to the outside of the bag.

In such a package of individual wrapped pants-type absorbent articles, it is desirable that the oxygen permeability of the packaging material is lower than the oxygen permeability of the bag body.

This type of packaging for individual wrappers of pants-type absorbent articles reduces the outflow of volatile substances and makes it easier to maintain the volatile substances inside the individual wrapper, compared to when the oxygen permeability of the packaging material is higher than that of the bag body.

In the package of the individual package of the pant-type absorbent article, in the packaged state, the packaging materials are joined together, and have end joints that run along the left-right direction of the pant-type absorbent article and are provided at the ends of the packaging materials, the end joints have one-side end joints and the other-side end joints at one end and the other end of the packaging materials in the up-down direction of the pant-type absorbent article, respectively, and the joint strength of the one-side end joint is stronger than the joint strength of the other-side end joint, and it is desirable that, in a state in which the individual package of the pant-type absorbent article is contained in the bag, the up-down direction of the pant-type absorbent article runs along the up-down direction of the package of the individual package of the pant-type absorbent article, and the other-side end joint is in contact with the bottom surface of the bag.

With this type of package for individual wrapped pants-type absorbent articles, even if the other end joint has a lower joining strength, the other end joint is in contact with the bottom surface of the bag, making it difficult for a gap to form between the other end joint and the bottom surface of the bag, thereby reducing the risk of volatile substances leaking out from the other end joint.

====Present Embodiment====
Hereinafter, as an example of the pants-type absorbent article according to the present embodiment, a pants-type absorbent article (hereinafter also referred to as "absorbent article") serving as a so-called shorts-type sanitary napkin will be described. However, the pants-type absorbent article is not limited to shorts-type sanitary napkins, and may be, for example, pants-type disposable diapers for adults or pants-type disposable diapers for infants. The "pants-type absorbent article" refers to an absorbent article in which the left and right ends of the ventral waist portion and the rear waist portion are separably joined or inseparably joined at least when contained in a packaging material (described later).

<<<Absorbent article 1>>>
FIG. 1 is a schematic perspective view of an absorbent article 1 in an unfolded and natural state. As shown in FIG. 1, the absorbent article 1 has a "vertical direction", a "lateral direction", and a "front-rear direction" that are mutually orthogonal in the unfolded state. The "unfolded state" refers to the absorbent article 1 in its natural state in which all of the folds of the absorbent article 1 are unfolded. The "natural state" refers to the state when the diaper 1 is left for a predetermined time. In the vertical direction of the pants-like absorbent article 1 (see FIG. 1), the waist opening 1a side of the absorbent article 1 is the "upper side", and the crotch side (the crotch portion 10m side) is the "lower side". In addition, in the front-rear direction, the front side is also the "ventral side", and the rear side is also the "dorsal side".

2 is a plan view of the absorbent article 1 in a separated flat state and stretched state, as seen from the skin side. The "separated flat state" refers to a state in which the side end joints 10e, 10e at both left and right ends of the pants-type absorbent article 1 are untied, the ventral waistline portion 10f and the rear waistline portion 10b are separated, and the absorbent article 1 is opened up and down and spread out flat. The "stretched state" refers to a state in which the absorbent article 1 is stretched without wrinkles, specifically, a state in which the dimensions of each component constituting the diaper 1 (e.g., the outer body 10 and the absorbent main body 20, which will be described later, etc.) are stretched to the same length or close to the dimensions of the component alone. The absorbent article 1 in the separated flat state and stretched state has a "longitudinal direction," "left-right direction," and "thickness direction" that are perpendicular to each other. The "longitudinal direction" of the absorbent article 1 is along the "up-down direction" of the absorbent article 1 in the unfolded and natural state of FIG. 1, and the "thickness direction" of the absorbent article 1 shown in FIG. 2 is along the "front-back direction" of the absorbent article 1 in the unfolded and natural state of FIG. 1, with the side that contacts the wearer's skin being called the "skin side" and the opposite side to the skin side being called the "non-skin side." In addition, one side in the left-right direction is the "left side" of the wearer while wearing it, and the other side in the left-right direction is the "right side" of the wearer while wearing it. Line C-C in FIG. 2 etc. is the center line in the left-right direction.

The absorbent article 1 is a so-called two-piece type shorts-type napkin, and has an outer body 10 and an absorbent body 20 that absorbs excrement such as urine. In the following explanation, a two-piece type shorts-type napkin (pants-type absorbent article) is described, but it may also be a so-called three-piece type shorts-type napkin (pants-type absorbent article) in which the ventral waist portion and the posterior waist portion are arranged as separate bodies.

The absorbent article 1 has a ventral waist section 10f that covers the ventral side of the wearer, a crotch section 10m that is located between the crotch of the wearer, and a back waist section 10b that covers the back side of the wearer. The crotch section 10m is an area that is located between the ventral waist section 10f and the back waist section 10b in the longitudinal direction.

The exterior body 10 of the absorbent article 1 in the separated flat state and stretched state is a component that forms the outer shape of the absorbent article 1, and is roughly hourglass-shaped in plan view. In other words, the center part in the longitudinal direction is recessed inward in the left-right direction. When molded into a pants shape, these recessed parts become a pair of leg openings 1b. The exterior body 10 also has a one-side extension portion 10L located outside one side in the left-right direction from the absorbent main body 20, and an other-side extension portion 10R located outside the other side.

As shown in FIG. 2, in the absorbent article 1 in the separated flat state and stretched state, the ventral waistline portion 10f is located at one end of the absorbent body 20 in the longitudinal direction, and the back waistline portion 10b is located at the other end of the absorbent body 20 in the longitudinal direction. The ventral waistline portion 10f and the back waistline portion 10b each have a side end joint 10e at both ends that joins the ventral waistline portion 10f and the back waistline portion 10b. The absorbent article 1 in the separated flat state and stretched state shown in FIG. 2 is folded in half at a fold line CL along the left-right direction provided at approximately the center of the longitudinal direction, i.e., the crotch portion 10m, and the side end of the ventral waistline portion 10f and the side end of the back waistline portion 10b are joined at the side end joint 10e to form a pants-type article. The side end joint 10e can be formed by known joining means such as ultrasonic bonding, adhesive, or welding. When molded into a pants-type absorbent article, it becomes a pants-type absorbent article with a waist opening 1a and a pair of leg openings 1b. The fold line CL is approximately the center of the absorbent article 1 in the longitudinal direction and is a straight line along the left-right direction. In the pants-type absorbent article 1 shown in FIG. 1, it is the lowest end of the diaper 1 that has a folded-back portion and is the end of the crotch portion 10m.

<Exterior body 10>
The exterior body 10 comprises an exterior top sheet 11, an exterior back sheet 12, a ventral waist elastic member 13, and a rear waist elastic member 14, which are joined and fixed to each other by a hot melt adhesive or the like.

The exterior top sheet 11 and the exterior back sheet 12 have approximately the same shape and form the outer shape of the absorbent article 1. The exterior top sheet 11 can be formed of air-through nonwoven fabric, spunbond nonwoven fabric, SMS nonwoven fabric (spunbond meltblown spunbond nonwoven fabric), waterproof film, etc. The exterior back sheet 12 can be formed of air-through nonwoven fabric, spunbond nonwoven fabric, SMS nonwoven fabric (spunbond meltblown spunbond nonwoven fabric), etc. The outer ends (upper ends) of the ventral and dorsal sides in the longitudinal direction of the exterior back sheet 12 are folded back to the skin side, respectively, to have a ventral fold portion 10ff and a dorsal fold portion 10bf that wrap around the outer end (upper end) of the exterior top sheet 11. Note that the configuration may not have the ventral fold portion 10ff and the dorsal fold portion 10bf. However, by providing the absorbent article 1 with the ventral fold 10ff and the dorsal fold 10bf, the thickness of the exterior body 10 at the waist opening 1a can be increased, which makes it easier to reduce the amount of cooling agent 26 (described below) that flows out of the absorbent article 1 through the waist opening 1a.

The ventral waist elastic member 13 and the back waist elastic member 14 are provided in the ventral waist section 10f and the back waist section 10b, respectively, between the exterior top sheet 11 and the exterior back sheet 12 in the thickness direction. The ventral waist elastic member 13 and the back waist elastic member 14 are, for example, multiple rubber threads. The ventral waist elastic member 13 and the back waist elastic member 14 are joined and fixed with an adhesive such as a hot melt adhesive. The ventral waist elastic member 13 and the back waist elastic member 14 provide the ventral waist section 10f and the back waist section 10b with elasticity in the left-right direction.

In the ventral waist section 10f, it is preferable that the contraction force of the upper end of the waist opening 1a side caused by the contraction force of the ventral waist elastic member 13 is greater than the contraction force of the lower end located near the crotch. In addition, in the dorsal waist section 10b, it is preferable that the contraction force of the upper end of the waist opening 1a side caused by the dorsal waist elastic member 14 is greater than the contraction force of the lower end located near the crotch. This makes it easier to shrink the waist opening 1a, narrowing the waist opening 1a and making it easier to reduce the amount of cooling agent 26 that flows out of the absorbent article 1 through the waist opening 1a. In addition, the ventral waist section 10f and the dorsal waist section 10b may be provided with an elastic sheet that stretches in the left-right direction.

<Absorbent body 20>
The absorbent body 20 is joined to the skin side of the exterior body 10. Examples of a method for joining the absorbent body 20 to the exterior body 10 include known connection methods such as adhesives, heat sealing, ultrasonic sealing, and combinations of these.

Figure 3 is a plan view of the absorbent body 20 in Figure 2, and Figure 4 is a cross-sectional view taken along the line A-A in Figure 3. Figure 3 is a plan view of the absorbent body 20 as viewed from the skin side. The absorbent body 20 includes a liquid-absorbent absorbent (absorbent core) 22, a core wrap sheet 22a that covers the outer peripheral surface of the absorbent body 22, a first skin side sheet 24a, a second skin side sheet 24b, a non-skin side sheet 24c, a side sheet 24d, a crotch elastic member 30, and a cooling agent 26. Each member is joined by a known means such as an adhesive such as a hot melt adhesive, welding, or pressure bonding. In addition, a compression section 40 is provided in the region of the absorbent body 20 where the absorbent body 22 is provided, and is shaped approximately along the longitudinal direction by being compressed in the thickness direction from the skin side.

The absorbent body 22 is a liquid-absorbent material molded into a substantially rectangular shape, and is capable of absorbing urine and other excrement. Examples of the liquid-absorbent material that can be used include liquid-absorbent fibers such as pulp fibers, and highly absorbent polymers. The shape of the absorbent body 22 is not necessarily limited to the shape shown in FIG. 2. Examples of the core wrap sheet 22a include liquid-permeable sheets such as tissue paper and nonwoven fabric. However, the configuration may be such that these core wrap sheets 22a are not used.

The first skin side sheet 24a is a liquid-permeable sheet member that can come into contact with the wearer's skin when worn, and is approximately rectangular and has a planar size larger than the absorbent body 22. The second skin side sheet 24b is laminated on the non-skin side of the first skin side sheet 24a. The first skin side sheet 24a and the second skin side sheet 24b are each provided closer to the skin than the absorbent body 22. The first skin side sheet 24a and the second skin side sheet 24b are formed, for example, from a hydrophilic air-through nonwoven fabric or a spunbond nonwoven fabric. Note that the configuration may include only one of the first skin side sheet 24a and the second skin side sheet 24b. For example, the configuration may include the first skin side sheet 24a located closer to the skin than the absorbent body 22, and no sheet member (second skin side sheet 24b) may be provided between the first skin side sheet 24a and the absorbent body 22, or only a core wrap sheet may be provided between the first skin side sheet 24a and the absorbent body 22.

The non-skin side sheet 24c is a substantially rectangular sheet with a planar size larger than the absorbent body 22, and is a liquid-impermeable sheet that covers the absorbent body 22 from the non-skin side. Examples of the non-skin side sheet 24c include a polyethylene film and a polypropylene film.

The side sheet 24d is a substantially rectangular sheet member with a planar size larger than the absorbent body 22, and the side sheet 24d is formed, for example, from an air-through nonwoven fabric or a spunbond nonwoven fabric. The side sheet 24d covers both ends of the absorbent body 22 in the left-right direction when viewed from the skin side. Specifically, the side sheet 24d is folded from one end of the absorbent body 22 in the left-right direction toward the non-skin side in the thickness direction outside the one end of the absorbent body 22 in the left-right direction, covering the entire non-skin side of the absorbent body 22, and folded from the other end of the absorbent body 22 in the left-right direction toward the skin side in the thickness direction, covering the other end of the absorbent body in the left-right direction. An elastic member 50S is fixed to the side sheet 24d on the skin side of the absorbent body 22. A pair of three-dimensional gathers 50 is formed by the contraction of the elastic member 50S, and the three-dimensional gathers 50 become a leak-proof wall, reducing the risk of excrement leaking outside the absorbent body 20 in the left-right direction.

The crotch elastic member 30 is provided in the thickness direction on the non-skin side of the absorbent body 22 and the non-skin side sheet 24c, and on the skin side of the side sheet 24d, i.e., between the non-skin side sheet 24c and the side sheet 24d. In this embodiment, it is a plurality of (four) rubber threads along the longitudinal direction, but the number is not limited to this, and it may be a single thread or four or more, and it is not limited to rubber threads, but may be, for example, a band-shaped elastic sheet having elasticity.

The cooling agent 26 is provided on the inside of the absorbent article 1, and the area where the cooling agent 26 is provided (applied) is called the application area 26P, and in FIG. 3 and the like, the application area 26P is shown by sand hatching for convenience. The "inside of the absorbent article 1" refers to the skin side of the exterior back sheet 12, which is the outermost sheet of the absorbent article 1. In this embodiment, the cooling agent 26 is applied to the non-skin side of the first skin side sheet 24a, and as shown in FIG. 3, the application area 26P is provided in the center in the left-right direction of the absorbent body 22, in the area excluding both side ends, and over the entire longitudinal area of the absorbent body 22. In particular, it is preferable to provide the cooling agent 26 in the center in the left-right direction of the absorbent body 22 so that it abuts against the excretory opening (vaginal opening) of the wearer when worn. In this embodiment, the application area 26P is provided on the first skin side sheet 24a, but this is not limited to this, and it can be arranged arbitrarily inside the absorbent article 1. However, in order to make the wearer's skin feel the effect of the cooling agent 26, it is preferable to provide the application area 26P in the absorbent body 20. It is also more preferable to provide the cooling agent 26 on the non-skin side of the first skin side sheet 24a. In this case, in the absorbent article 1, it is preferable that the amount of cooling agent 26 held by the first skin side sheet 24a is greater than the amount of cooling agent 26 held by the side sheet 24d. Since the first skin side sheet 24a is the member of the absorbent body 20 that is located closest to the wearer's skin when worn, it is easier for the wearer to feel the effect of the cooling agent 26 provided in the first skin side sheet 24a. On the other hand, by reducing the amount of cooling agent 26 held by the side sheet 24d, it is possible to reduce the risk of the adhesiveness of the adhesive, such as a hot melt adhesive, that fixes the elastic member 50S to the side sheet 24d decreasing.

The cooling agent 26 is a substance for reducing discomfort caused by stuffiness and stickiness to the wearer, and is a substance that includes a cooling stimulant that stimulates the wearer's temperature sense. The cooling stimulant of this embodiment uses a substance that can exert a cooling effect when worn. For example, when excrement such as urine or menstrual blood is excreted and the absorbent body 20 absorbs the excrement, the wearer is likely to feel discomfort due to the excrement and is unlikely to feel the effect of the cooling agent 26. In contrast, the cooling stimulant used in the cooling agent 26 of this embodiment does not exert its effect in response to moisture contained in the excrement, and by using a substance that can obtain a cooling effect from the moment the wearer wears the absorbent article 1, the wearer is more likely to feel the effect of the cooling agent 26 and is more likely to feel a refreshing sensation due to the cooling agent 26. The cooling agent 26 provided in the absorbent article 1 is applied in a state mixed with a volatile solvent, and is therefore highly volatile.

From the viewpoint of comfort for the wearer, it is preferable that the cooling stimulant is derived from a plant. Examples of cooling stimulants include menthol (e.g., l-menthol, etc.); menthol derivatives (e.g., menthyl lactate, menthyl glyceryl ether, etc.); methyl salicylate; and essential oils derived from plants such as mint and eucalyptus.

The cold sensation stimulant of the cooling agent 26 is preferably one that stimulates a temperature-sensitive TRP channel. For example, TRPM8, which is one type of temperature-sensitive TRP channel, is a cold sensation receptor that acts as a cold sensation sensor. Menthol (e.g., l-menthol) and its derivatives (e.g., menthyl lactate) activate TRPM8, thereby causing the cold sensation sensor to react even if the temperature has not actually decreased, and thus providing a feeling of coolness to the wearer. In other words, it is preferable that the agent itself does not absorb heat and lower the temperature, but rather makes the wearer feel a sense of coolness. Therefore, the wearer can feel a sense of coolness without excessively cooling the skin.

The cooling sensation agent 26 is more likely to exert its effect by coming into direct contact with the wearer's skin. For example, a volatile substance such as a fragrance can suppress surrounding odors when it becomes a gas, but the cooling sensation agent 26 exerts its main effect by coming into direct contact with the wearer's skin after vaporizing. In other words, the cooling sensation agent 26 comes into contact with the wearer's skin via a nonwoven fabric (first skin-side sheet 24a) or the like, and the wearer can gradually feel the effect of the cooling sensation agent 26 on his or her skin.

The solvent is not particularly limited as long as it can contain a cooling stimulant, and examples of the solvent include lipophilic solvents and hydrophilic solvents. The solvent can dissolve or disperse the cooling stimulant, for example.

Lipophilic solvents include fats and oils, such as natural oils (e.g., fatty acid esters such as triglycerides, coconut oil, linseed oil, tri(caprylic/capric acid)glyceryl, etc.), and hydrocarbons (e.g., paraffin, e.g., liquid paraffin), etc.

Hydrophilic solvents include water and alcohols. Examples of the alcohols include lower alcohols such as methanol, ethanol, ethylene glycol, and glycerin, and higher alcohols such as capryl alcohol, lauryl alcohol, and myristyl alcohol.

<<<Individually packaged body 100>>>
The absorbent article 1 is packaged in a packaging material 101 to become an individual package 100. Fig. 5 is a plan view of the individual package 100. The absorbent article 1 in the individual package 100 is folded at folding portions LB, RB, and BL along the top-bottom and left-right directions and is stored inside the packaging material 101. Hereinafter, the individual package 100 and the absorbent article 1 packaged in the packaging material 101 are referred to as the "individual package 100 in a packaged state" and the "absorbent article 1 in a packaged state," and the absorbent article 1 in a state that can be packaged in the packaging material 101 is also referred to as the "folded state."

5 and other figures, the left-right and up-down directions of the absorbent article 1 are aligned with the left-right and up-down directions of the individual packaging body 100, and the front-rear direction of the absorbent article 1 is aligned with the thickness direction of the individual packaging body 100. In addition, in the packaged state, the packaging material 101 has a folding direction along the folds LC1 and LC2 (described later), an orthogonal direction perpendicular to the folding direction, and a thickness direction perpendicular to the folding direction and the orthogonal direction. In the packaged individual packaging body 100, the folding direction of the packaging material 101 is aligned with the up-down direction of the individual packaging body 100 and the absorbent article 1, the orthogonal direction of the packaging material 101 is aligned with the left-right direction of the individual packaging body 100 and the absorbent article 1, and the thickness direction of the packaging material 101 is aligned with the thickness direction of the individual packaging body 100 and the front-rear direction of the absorbent article 1.

<Absorbent article 1 in folded state>
The absorbent article 1 in the folded state refers to a state in which the absorbent article 1 in the unfolded state is folded at folding parts along the up-down direction and the left-right direction. Fig. 6 is a schematic diagram of the absorbent article 1 in the unfolded state as seen from the back side. For convenience, one side leg opening 1b in Figs. 6 to 12 is shown by a diagonal line slanting downward to the left.

The folded absorbent article 1 (see FIG. 8) is formed by folding the unfolded state shown in FIG. 6 at the folding reference positions B1, B2, and B3. The folding reference positions B1, B2, and B3 are positions that serve as references (fulcrums) when folding the absorbent article 1. The absorbent article 1 (individually packaged body 100) is first folded from the unfolded state shown in FIG. 6 toward the inside in the left-right direction at the folding reference positions B1 and B2. The folding reference position B1 is a reference position for folding along the up-down direction, and is provided at any position on the one-side extension portion 10L. The folding reference position B2 is a reference position for folding along the up-down direction, and is provided at any position on the other-side extension portion 10R. The folding reference position B3 is a reference position for folding along the left-right direction, and is provided below the center in the up-down direction of the unfolded absorbent article 1 (crotch side).

From the unfolded state shown in FIG. 6, first, the part of the one-side extension portion 10L that is outside the folding reference position B1 in the left-right direction is folded toward the back side to obtain the state shown in FIG. 7A, and then the part of the other-side extension portion 10R that is outside the folding reference position B2 in the left-right direction is folded toward the back side to obtain the state shown in FIG. 7B. FIG. 7A is a diagram showing the absorbent article 1 of FIG. 6 folded at the folding reference position B1. FIG. 7B is a diagram showing the absorbent article 1 of FIG. 7A folded at the folding reference position B2. As shown in FIG. 7B, by folding at the folding reference positions B1 and B2, a part of the folded part of the one-side extension portion 10L and a part of the folded part of the other-side extension portion 10R are overlapped in the thickness direction (front-back direction). This allows the length of the absorbent article 1 in the folded state in the left-right direction to be shorter. Either the one-side extension portion 10L or the other-side extension portion 10R can be folded first.

In addition, in the state (FIG. 7B) where the one-side extension portion 10L and the other-side extension portion 10R are folded at the folding reference position B1 and the folding reference position B2 shown in FIG. 7A and FIG. 7B, respectively, when the absorbent article 1 is viewed from the top (e.g., the back side) in the thickness direction (front-rear direction), the end on the one side in the left-right direction is called the "one-side folded portion LB", the end on the other side in the left-right direction is called the "other-side folded portion RB", and the one-side folded portion LB and the other-side folded portion RB are also called the "left-right folded portion". The one-side folded portion LB and the other-side folded portion RB are each aligned in the up-down direction. Since the absorbent article 1 has a predetermined thickness, the one-side folded portion LB and the other-side folded portion RB in the folded state are located outside the folding reference position B1 and the folding reference position B2, respectively, in the left-right direction. In the unfolded state, the folded portion LB on one side overlaps with the folding reference position B1 in the front-to-back direction (thickness direction), and the folded portion RB on the other side overlaps with the folding reference position B2 in the front-to-back direction (thickness direction). In addition, in this embodiment, the "left and right folded portions LB, RB along the vertical direction" are described as being parallel to the vertical direction of the absorbent article 1, but this is not limited to this. The left and right folded portions LB, RB along the vertical direction may each be inclined within a range of 45 degrees with respect to the vertical direction.

Next, the absorbent article 1 in the folded state shown in FIG. 8 is obtained by folding the portion (crotch side) below the folding reference position B3 in the vertical direction toward the upper side (the waist opening 1a side) of the absorbent article 1 in the state shown in FIG. 7B. FIG. 8 is a diagram showing the absorbent article 1 in the folded state. When the absorbent article 1 is folded in the vertical direction at the folding reference position B3 along the left-right direction and viewed from above in the thickness direction, the lowermost end in the vertical direction is called the "vertical folding portion BL". The vertical folding portion BL is along the left-right direction. Since the absorbent article 1 has a predetermined thickness, the vertical folding portion BL in the folded state is located above the folding reference position B3 in the vertical direction (the waist opening 1a side). In addition, in this embodiment, the "vertical folding portion BL along the left-right direction" is described as being parallel to the left-right direction of the absorbent article 1, but is not limited to this. The upper and lower folding parts BL along the left-right direction may be inclined within a range of 45 degrees with respect to the left-right direction. In the unfolded state, the upper and lower folding parts BL overlap with the folding reference position B3 in the front-rear direction (thickness direction). In addition, as shown in FIG. 3, in the unfolded state, it is preferable that the folding reference position B3 is provided so as to be perpendicular to the up-down direction of the absorbent body 22. In addition, the folding reference position B3 may be provided so as to intersect with the compression part 40 provided in the absorbent main body 20. The absorbent body 22 is a member having high rigidity in the absorbent article 1. Similarly, the compression part 40 is a part having even higher rigidity in the absorbent article 1. By folding at the part intersecting with the compression part 40 having high rigidity, it becomes easier to give the absorbent body 22 a so-called crease, and the folded state of the absorbent article 1 is easier to maintain, so that the cooling agent 26 provided on the inside of the absorbent article 1 is more likely to volatilize through the waist opening 1a.

<Packaging method using packaging material 101>
A method of packaging the absorbent article 1 in a folded state with a packaging material 101 will be described. FIG. 10 is a diagram showing a state of a first packaging step. In the first packaging step, as shown in FIG. 10, a rectangular packaging material 101 larger than the absorbent article 1 in a folded state is horizontally spread, and the absorbent article 1 in a folded state is placed at approximately the center of the packaging material 101. At this time, in the thickness direction (front-rear direction) of the absorbent article 1 in the folded state, the waist opening 1a (waist portion 10f, 10b) side is the side that contacts the packaging material 101 (lower side), and the crotch portion 10m side is the upper side. Note that the first folding reference position L1 shown in FIG. 10 is a reference position for folding the packaging material 101 in the second packaging step, and the second folding reference position L2 is a reference position for folding the packaging material 101 in the third packaging step. At this time, the first folding reference position L1 and the second folding reference position L2 are set so as to be aligned along the vertical direction of the absorbent article 1.

The packaging material 101 is made of a material that is difficult to transmit volatile substances such as the cooling agent 26 (so-called high gas barrier properties), thereby reducing the risk that the cooling agent 26 included in the absorbent article 1 will leak out of the individual package 100. As the packaging material 101 that is difficult to transmit volatile substances, a sheet member having an oxygen permeability in the thickness direction of 200 cc/ ^m2 /day/atm or less at 23°C is used. Since the permeability of volatile substances in the thickness direction of the packaging material 101 is approximately proportional to the oxygen permeability, the degree to which volatile substances permeate in the thickness direction of the packaging material 101 is specified using the oxygen permeability in the thickness direction of the packaging material 101.

The packaging material 101 may be, for example, a sheet member formed of EVOH resin (ethylene-vinyl alcohol copolymer resin), PET (polyester), polyvinyl alcohol, polyvinyl chloride (PVC), nylon, or the like. The packaging material 101 of this embodiment is a sheet of a multi-layer film material of PE/admer/EVOH/admer/PE containing EVOH resin (ethylene-vinyl alcohol copolymer resin), and has an oxygen permeability of 2.0 cc/ ^m2 /day/atm. The oxygen permeability of the packaging material 101 may be measured by a known method such as the coulometric method (MOCON method) under conditions of 23°C and 0% RH.

Specifically, first, a filter paper soaked in menthol, which is the cooling agent 26, and a packaging material 101 made of EVOH resin are prepared, and the weights of the filter paper and packaging material 101 are measured. Next, the filter paper containing menthol is placed on the packaging material 101 made of EVOH resin, folded in three, and the weight of sample A in the state of being sealed with a sealing member is measured. The weight of the filter paper not containing menthol is subtracted from the weight of the packaging material 101 from the weight of sample A in this state to obtain the weight of menthol contained in the filter paper. After that, the weight of sample A is measured after a predetermined time under predetermined conditions (for example, one week and four weeks in a constant temperature and humidity chamber at 40°C and 70%), and the weight reduction from before the predetermined time is calculated to obtain the outflow amount of menthol, which is the cooling agent 26. In addition, the weight of menthol after the predetermined time has passed and the weight of menthol before the predetermined time have passed can be compared to calculate the reduction rate of menthol. It is preferable to measure the outflow amount of menthol a predetermined number of times (for example, 10 times) and obtain the average value.

Similarly, the outflow amount of menthol, which is the cooling agent 26, can be obtained by the same method for each of sample B, in which filter paper containing menthol is placed on a sheet made of PET, folded in thirds, and sealed with a sealing member; sample C, in which filter paper containing menthol is placed on a sheet made of polyvinyl chloride (PVC), folded in thirds, and sealed with a sealing member; and sample D, in which filter paper containing menthol is placed on a sheet made of PE (polyethylene), folded in thirds, and sealed with a sealing member. The size of the filter paper and the size of the sheet for each sample are the same.

Figure 9 shows the measurement results of the amount of menthol that leaks out. In Figure 9, each weight and percentage shows an average value. The weight of menthol at the start of measurement for sample A (EVOH resin, packaging material 101) is 0.5 g, the weight of menthol after one week has decreased by 2% from the start of measurement, and the weight of menthol after four weeks has decreased by 2% from the start of measurement. The weight of menthol at the start of measurement for sample B (sheet made of PET) is 0.5 g, the weight of menthol at the start of measurement is 0.5 g, the weight of menthol after one week has decreased by 2% from the start of measurement, and the weight of menthol after four weeks has decreased by 2% from the start of measurement. The weight of menthol at the start of measurement for sample C (sheet made of PVC) is 0.5 g, the weight of menthol after one week has decreased by 6% from the start of measurement, and the weight of menthol after four weeks has decreased by 10% from the start of measurement. The weight of menthol at the start of the measurement for sample D (PE sheet) was 0.5 g, the weight of menthol after one week had decreased by 32% from the start of the measurement, and the weight of menthol after four weeks had decreased by 98% from the start of the measurement.

The oxygen permeabilities of the sheet members used in samples A to D were 2.0 cc/ ^m2 /day/atm for the EVOH resin sheet, 80 cc/ ^m2 /day/atm for the PET sheet, 200 cc/ ^m2 /day/atm for the PVC sheet, and 7900 cc/ ^m2 /day/atm for the PE sheet, respectively.

When comparing the weight of the cooling sensation agent 26 of samples A to D before and after a predetermined time has elapsed, if the rate of decrease in menthol is 10% or less, the wearer will easily notice the cooling sensation agent 26 in the crotch area (the area in contact with the absorbent body 20) when wearing the sample. Regarding the weight of the cooling sensation agent 26 of samples A to D after 4 hours has elapsed, the results showed that a predetermined weight of menthol remained in the sheets made of EVOH resin, PET, aluminum, and PVC, each of which has an oxygen permeability of 200 cc/ ^m2 / ^day /atm or less, whereas almost no menthol remained in the sheet made of PE, which has an oxygen permeability of more than 200 cc/m2/day/atm. In addition, the EVOH resin sheet, the PET sheet, and the PVC sheet showed small changes in the menthol reduction rate after one week and four weeks, whereas the PE sheet showed a large change in the menthol reduction rate after one week and four weeks, indicating that menthol leaked out through the PE sheet over time.

From the results of the outflow amount of cooling agent 26 for Samples A to D, it can be seen that when a sheet made of PVC with an oxygen permeability of 200 cc/m ² /day/atm (Sample C) is used as the packaging material 101, it has gas barrier properties sufficient to make the effect of the cooling agent 26 noticeable, whereas when a sheet made of PE (Sample D) is used as the packaging material 101, it does not have gas barrier properties sufficient to make the effect of the cooling agent 26 noticeable. Therefore, it is preferable to use a sheet member for the packaging material 101 whose oxygen permeability in the thickness direction is 200 cc/m ² /day/atm or less.

The packaging material 101 is folded at the folding reference position L1 so that the first folded portion 101L on one side in the left-right direction of the packaging material 101 is folded toward the other side in the left-right direction and so that the first folded portion 101L covers the crotch portion 10m side of the absorbent article 1 in the folded state, resulting in the state of the second packaging step shown in FIG. 11. FIG. 11 is a diagram showing the state of the second packaging step. In FIG. 11, the folded first folded portion 101L is shown by a diagonal line that slopes downward to the left. As shown in FIG. 11, in the second packaging step, by setting the folding reference position L1 to the end of one side in the left-right direction of the absorbent article 1, it is possible to achieve a state in which there is almost no gap (small gap) between the absorbent article 1 and the packaging material 101 on one side in the left-right direction. In addition, when the first fold 101L is folded at the folding reference position L1, the end on the one side in the left-right direction when the individual package 100 (the individual package 100 in the middle of being packaged) is viewed from the top (e.g., the back side) in the thickness direction (the front-to-rear direction of the absorbent article 1) is referred to as the "one-side fold LC1."

In the second packaging step, adhesive 101h such as a hot melt adhesive is applied to the other end in the left-right direction of the outer surface of the first folded portion 101L. The adhesive 101h is an adhesive portion for joining the first folded portion 101L and the second folded portion 101R to form the joint portion 102. It is preferable that the adhesive 101h is continuously applied from the upper end to the lower end of the packaging material 101 in the vertical direction of the absorbent article 1 in order to prevent foreign matter from entering the inside of the individual package 100 and to reduce the risk of the cooling agent (volatile substance) 26 provided in the absorbent article 1 leaking out of the individual package 100. In addition, since the adhesive 101h only needs to bond the outer surface of the first folded portion 101L and the inner surface of the second folded portion 101R, the adhesive 101h may be provided on the inner surface of the second folded portion 101R without providing the adhesive 101h on the outer surface of the first folded portion 101L.

Next, the packaging material 101 is folded at the folding reference position L2 so that the second folded portion 101R on the other side in the left-right direction of the packaging material 101 is folded toward one side in the left-right direction so that the first folded portion 101L and the second folded portion 101R cover the end side of the crotch portion 10m of the absorbent article 1 in the folded state, resulting in the third packaging step state shown in FIG. 12. FIG. 12 is a diagram showing the state of the third packaging step. In FIG. 12, the folded second folded portion 101R is shown by a diagonal line that slopes downward to the right. As shown in FIG. 12, in the third packaging step, by setting the folding reference position L2 to the other end of the absorbent article 1 in the left-right direction, it is possible to make the other side in the left-right direction into a state in which there is almost no gap (small gap) between the absorbent article 1 and the packaging material 101. In addition, when the second fold 101R is folded at the folding reference position L2, the othermost end in the left-right direction when the individual package 100 (the individual package 100 in the middle of being packaged) is viewed from the top (e.g., the back side) in the thickness direction (the front-to-rear direction of the absorbent article 1) is referred to as the "other-side fold LC2."

In the third packaging process, the other end of the first folded portion 101L in the left-right direction and the one end of the second folded portion 101R in the left-right direction are overlapped at approximately the center in the left-right direction, and are joined with adhesive 101h provided on the outer surface of the first folded portion 101L in the second packaging process to form the inner joint 102. In other words, the inner joint 102 is a joint made by adhesive 101h. It is preferable that the inner joint 102 is along the one-side folded portion LC1 and the other-side folded portion LC2, along the up-down direction, and is continuous from the end on one side to the end on the other side in the up-down direction. In addition, the inner joint 102 is provided inside the one-side folded portion LC1 and inside the other-side folded portion LC2 in the left-right direction (orthogonal direction). In other words, the inner joint 102 is provided between the one-side folded portion LC1 and the other-side folded portion LC2 in the left-right direction, and is provided in approximately the center in the orthogonal direction in the individual package 100. Through the third packaging process, the packaging material 101 has a surface in the thickness direction that does not have the inner joint portion 102 and a surface that has the inner joint portion 102.

In this embodiment, the first folded portion 101L of the packaging material 101 is folded at the folding reference position L1 in the second packaging process, and the second folded portion 101R of the packaging material 101 is folded at the folding reference position L2 in the third packaging process, but this is not limited to this. The second folded portion 101R of the packaging material 101 may be folded in the second packaging process, and the first folded portion 101L may be folded in the third packaging process.

Finally, in the fourth packaging step, a pair of end joints 103 are formed. One-side end joint 103a and other-side end joint 103b are formed at one end and the other end of the packaging material 101 in the vertical direction (orthogonal direction), respectively. One-side end joint 103a and other-side end joint 103b are each jointed by welding with the application of heat and pressure. It is preferable that one-side end joint 103a and other-side end joint 103b are continuous from one end to the other end in the left-right direction (orthogonal direction). By forming the pair of end joints 103, the absorbent article 1 is contained in the packaging material 101, and becomes an individually packaged body 100 as shown in FIG. 5.

<Individually wrapped body 100 in a packaged state>
The individual package 100 of an absorbent article 1 such as a sanitary napkin is desirably in a compact shape for reasons such as portability, and it is desired that the wearer be able to feel the effect of the volatile substance such as the cooling agent 26 of the absorbent article 1 when the absorbent article 1 is taken out of the compact shape. The volatile substance such as the cooling agent 26 provided on the inside of the absorbent article 1 is likely to flow out to the outside of the absorbent article 1 from the waist opening 1a and leg openings 1b that are open as "openings."

In the individual package 100, the absorbent article 1 including the cooling agent 26 is folded at left and right folds LB and RB along the vertical direction and at top and bottom folds BL along the horizontal direction, and is packaged in a packaging material 101 including a one-side fold LC1. The packaging material 101 has an oxygen permeability of 200 cc/ ^m2 /day/atm or less, and the one-side fold LC1 is aligned with the vertical direction of the absorbent article 1.

Typically, pants-type absorbent articles are provided with leg openings 1b facing both outside in the left-right direction perpendicular to the up-down direction. Therefore, one side folded portion LC1 of the packaging material 101 located outside the absorbent article 1 in the left-right direction is aligned along the up-down direction of the absorbent article 1, so that one side folded portion LC1 of the packaging material 101 having an oxygen permeability of 200 cc/ ^m2 /day/atm or less can cover at least a part of the leg opening 1b on one side in the left-right direction, and can play the role of a lid that reduces the outflow of the cooling agent 26 flowing out from the leg opening 1b on one side to the outside of the individual package 100.

If a joint portion where the packaging materials 101 aligned in the up-down direction are joined to each other is provided on one side of the absorbent article 1 in the left-right direction, there is a risk that the cooling agent 26 will leak out from the gap at the joint portion. In contrast, as in the absorbent article 1, the one-side folded portion LC1 of the seamless packaging material 101 having an oxygen permeability of 200 cc/ ^m2 /day/atm or less is provided along the up-down direction of the absorbent article 1 and on one side of the absorbent article 1, thereby reducing the risk that the cooling agent 26 leaking out from the leg opening 1b on one side will leak out to the outside of the individual package 100. By reducing the risk that the cooling agent 26 leaking out from the leg opening 1b on one side will leak out to the outside of the individual package 100, the risk that the amount of the cooling agent 26 inside the individual package 100 will decrease is reduced, and the wearer can easily feel the effect of the cooling agent 26 when opening the individual package 100 or wearing the absorbent article 1.

In addition, by providing the absorbent article 1 in a folded state and providing a one-side folded portion LC1 along the up-down direction on one side of the absorbent article 1 in the left-right direction, the left-right length of the individual package 100 can be shortened and the individual package 100 can be made into a more compact shape than when a joint is provided on one side of the absorbent article 1 in the left-right direction, joining packaging materials 101 along the up-down direction. In other words, the difference between the left-right length of the absorbent article 1 in the folded state and the left-right length of the individual package 100 can be made shorter. In this case, it is preferable that the absorbent article 1 in the packaged state (folded state) is in contact with the packaging material 101 on at least one of the left-right sides.

Furthermore, the cooling agent 26 contains a volatile solvent and evaporates while containing the cooling stimulant, and there is a risk that the evaporation of the cooling agent 26 may be accelerated by external stimuli, circulation of outside air, and the like. In response to this, by making the individual package 100 compact and shortening the difference between the left-right length of the absorbent article 1 in the folded state and the left-right length of the individual package 100, it is possible to reduce the movement of the absorbent article 1 relative to the package 101 inside the individual package 100. As a result, it becomes easier to reduce the evaporation of the cooling agent 26, and the wearer is more likely to feel the effect of the cooling agent 26. Note that the "flow" of the cooling agent 26 includes not only the flow of the cooling agent 26 in a liquid or solid state, but also the flow of the cooling agent 26 in a vaporized state.

The absorbent article 1 has a pair of leg openings 1b that open toward both sides in the left-right direction, and the packaging material 101 has not only one side folded portion LC1 but also the other side folded portion LC2. This reduces the cooling agent 26 that flows out from the leg opening 1b on one side in the left-right direction of the absorbent article 1 to the outside of the individual package 100, and reduces the cooling agent 26 that flows out from the leg opening 1b on the other side in the left-right direction to the outside of the individual package 100. Therefore, when opening the individual package 100 or wearing the absorbent article 1, the wearer is more likely to feel the effect of the cooling agent 26. Note that since the individual package 100 has a shape that is approximately symmetrical in the left-right direction (orthogonal direction), the characteristics of the one side folded portion LC1 are the same as the characteristics of the other side folded portion LC2, and detailed description below will be omitted.

In the absorbent article 1 in an unfolded and natural state, it is preferable that the cooling agent 26 is provided on the crotch side of the upper and lower folds BL in the vertical direction. FIG. 3 shows the positions corresponding to the upper and lower folds BL in the absorbent main body 20 of the absorbent article 1 in an unfolded and natural state. The cooling agent 26 provided on the crotch side of the upper and lower folds BL of the absorbent article 1 in an unfolded and natural state is sandwiched between the upper and lower folds BL and the crotch portion 10m in the folded state, which reduces the risk of the cooling agent 26 leaking out of the absorbent article 1 and further reduces the cooling agent 26 leaking out of the individual package 100.

In addition, in the absorbent article 1 in the unfolded and natural state, it is preferable that the cooling agent 26 is provided inside the left and right folding parts LB, RB that are provided outside the absorbent body 22 in the left and right direction. As shown in FIG. 6 and other figures, the left and right folding parts LB, RB of the absorbent article 1 are outside the absorbent main body 20 in the left and right direction, and are therefore clearly outside the absorbent body 22. In the folded absorbent article 1, the cooling agent 26 provided inside the left and right folding parts LB, RB in the left and right direction can be folded at the left and right folding parts LB, RB to narrow the path for the cooling agent 26 to flow out of the leg openings 1b, thereby reducing the risk of the cooling agent 26 flowing out to the outside of the absorbent article 1 and reducing the amount of cooling agent 26 that flows out to the outside of the individual package 100.

As shown in FIG. 5 and other figures, the individual package 100 in the packaged state has an end joint 103 along the left-right direction (orthogonal direction). As described above, in order to seal the individual package 100, end joints 103a and 103b that join the packaging materials 101 to each other are provided at both ends in the up-down direction (folding direction). When the absorbent article 1 is placed in the center of the individual package 100 in the up-down direction inside the packaging material 101 of this individual package 100, it is preferable that the longest distance between the one-side folded portion LC1 and the absorbent article 1 is shorter than the longest distance between the end joint 103a (or 103b) and the absorbent article 1. For example, as shown in FIG. 5, when the absorbent article 1 is placed in the center of the individual package 100 in the up-down direction inside the individual package 100, the longest distance between the one-side LC1 and the absorbent article 1 in the left-right direction is shorter than the longest distance X between the end joint 103a (or 103b) and the absorbent article 1 in the up-down direction. In this embodiment, the end joint portion 103a (103b) and the absorbent article 1 are spaced apart by a predetermined distance (longest distance X) in the up-down direction, whereas the one-side folded portion LC1 and the absorbent article 1 are in contact with or close to each other in the left-right direction, and the distance between the one-side folded portion LC1 and the absorbent article 1 is extremely short, close to zero. Therefore, when the absorbent article 1 is disposed in the center of the individual package 100 in the up-down direction, the longest distance between the one-side folded portion LC1 and the absorbent article 1 is clearly shorter than the longest distance X between the end joint portion 103a and the absorbent article 1. This makes it possible to narrow the space between the one side folded portion LC1 and the absorbent article 1 in the left-right direction compared to when the longest distance between the one side folded portion LC1 and the absorbent article 1 is longer than the longest distance X between the end joint portion 103a and the absorbent article 1, thereby reducing the circulation of air that promotes the evaporation of the cooling agent 26 and reducing the amount of cooling agent 26 that flows out of the absorbent article 1 into the packaging material 101 through the leg openings 1b, making it easier to reduce the amount of cooling agent 26 that flows out of the packaging material 101 (individually packaged body 100).

In FIG. 5 and other figures, it has been described that when the absorbent article 1 is placed in the center of the individual packaging body 100 in the vertical direction, the longest distance between the one side folded portion LC1 and the absorbent article 1 is shorter than the longest distance X between the end joint portion 103a (103b) and the absorbent article 1. However, even when the absorbent article 1 is placed in any position in the vertical direction of the individual packaging body 100, by making the longest distance between the one side folded portion LC1 and the absorbent article 1 shorter than the longest distance X between the end joint portion 103a (103b) and the absorbent article 1, the amount of cooling agent 26 that flows out from the absorbent article 1 into the packaging material 101 through the leg openings 1b can be reduced, and the amount of cooling agent 26 that flows out to the outside of the packaging material 101 (individual packaging body 100) can be reduced.

As described above, the absorbent article 1 of the individual package 100 in the packaged state is in a folded state in which it is folded at the top and bottom folding parts BL and the left and right folding parts LB, RB. The individual package 100 in the packaged state also has an inner joint 102 provided inside the one-side folding part LC1 (the other-side folding part LC2) in the left-right direction (orthogonal direction). The inner joint 102 is along the up-down direction (folding direction). It is preferable that the inner joint 102 is provided at a position closer to the crotch part 10m than the waist opening 1a in the front-rear direction of the absorbent article 1. That is, as described above (see Figures 10 to 12), the packaging material 101 has a surface on which the inner joint 102 is not provided and a surface on which the inner joint 102 is provided in the thickness direction, and it is preferable that the surface on which the inner joint 102 is not provided is located on the waist circumference parts 10f, 10b side, and the surface on which the inner joint 102 is provided is provided at a position closer to the crotch part 10m.

In general, a shorts-type napkin (pants-type absorbent article) such as the absorbent article 1 has an absorbent body 22 in the crotch portion 10m to absorb excrement. Usually, the absorbent body 22 has higher rigidity than the portion (waist portion 10f, 10b) where the waist opening 1a is provided. Therefore, by providing the inner joint 102 at a position close to the crotch portion 10m in the thickness direction, the inner joint 102 is formed in a more stable state, and the joint strength of the inner joint 102 is easily increased. In addition, by providing the waist opening 1a near a surface where the inner joint 102 is not provided in the thickness direction, the risk of the cooling agent 26 flowing out from the waist opening 1a flowing out to the outside of the individual package 100 through the inner joint 102 can be reduced.

Moreover, as shown in FIG. 5 etc., it is more preferable that the absorbent article 1 is folded in a state where the length N from the upper and lower folds BL to the waist opening 1a (the upper end of the absorbent article 1 in its natural state) in the vertical direction in the packaged individual package 100 is equal to or greater than the length M (N≧M) from the upper and lower folds BL to the end of the crotch portion 10m (the lower end of the absorbent article 1 in its natural state). By folding in the vertical direction, the leg opening 1b can be covered more widely and more reliably by the portion on the waist opening 1a side from the upper and lower folds BL. This reduces the risk of the cooling agent 26 leaking out from the leg opening 1b.

For the individual package 100, it is preferable that the bonding strength between the packaging materials 101 at the inner joint 102 is higher than the bonding strength between the packaging materials 101 at the one-side end joint 103a and the other-side end joint 103b. Because the bonding strength of the one-side end joint 103a or the other-side end joint 103b is lower than the bonding strength of the inner joint 102 for the individual package 100 before opening, the wearer is more likely to separate the bonding between the packaging materials 101 at the end joints 103a and 103b than when the bonding strength of the end joints 103a, 103b is higher than the bonding strength of the inner joint 102. On the other hand, since the bonding strength of the inner joint 102 is higher than that of the end joints 103a and 103b, the risk of the bonding of the packaging materials 101 at the inner joint 102 being separated can be reduced compared to when the bonding strength of the inner joint 102 is lower than that of the end joints 103a and 103b, so that the packaging material 101 of the individual package 100 after opening can be easily kept in a bag shape with either one of the end joints 103a and 103b opened. The bag-shaped packaging material 101 can be used to carry the absorbent article 1 after use, or to dispose of it, etc.

The "joint strength" between the packaging materials 101 at the inner joint 102 and the end joints 103a and 103b refers to the magnitude of the force per unit area required to separate (peel) the joints between the packaging materials 101 at each joint 102 and 103 of the individual package 100. In other words, the joint strength and the separation strength (peel strength) are the same magnitude of force.

The specific method of measuring the bonding strength is to first cut out samples 1 and 2 of the same area from the individual package 100 to be measured. Sample 1 is the part of the packaging material 101 where the inner joint 102 is provided, and sample 2 is the part of the packaging material 101 where the end joints 103a and 103b are provided. Next, sample 1 or sample 2 is set in the upper and lower chucks of a tensile tester (e.g., Instron Series 5564 manufactured by Instron Corporation). Then, the upper and lower chucks are separated at a predetermined pulling speed (e.g., 300 mm/min) and samples 1 and 2 are pulled. The maximum load (N) until the chuck distance is separated is obtained. Measurement results of n pieces (e.g., 10 pieces) are obtained for each of samples 1 and 2, and the average value of the n maximum loads (N) is calculated. Then, the average value (N) of sample 1 is taken as the bonding strength of the inner joint 102, and the average value (N) of sample 2 is taken as the bonding strength of the end joints 103a and 103b, and the two values can be compared. The bond strengths described below can also be compared using the same measurement method.

In addition, in the packaged state, it is preferable that one end and the other end of the absorbent article 1 in the vertical direction are provided with one end joint 103a and the other end joint 103b, the joint strength of the one end joint 103a is higher than the joint strength of the other end joint 103b, and the waist opening 1a of the absorbent article 1 is provided on one side in the vertical direction. In the vertical direction of the absorbent article 1 in the folded state, the waist opening 1a is a part that opens toward the inside of the absorbent article 1, so that the cooling agent 26 is more likely to volatilize than on the upper and lower folds BL side of the absorbent article 1. Therefore, when the one-side end joint 103a has a stronger joint strength than the other-side end joint 103b, the waist opening 1a can be oriented toward the one-side end joint 103a, which has a stronger joint strength, compared to when the waist opening 1a is provided on the other side in the vertical direction, thereby reducing the risk that the cooling agent 26 leaking from the waist opening 1a will flow out of the individual package 100 through the one-side end joint 103a.

<Individual package 110 in a packaged state according to another embodiment>
An individual package 110 of another embodiment will be described. Fig. 13A is a plan view of the individual package 110 of another embodiment. Regarding the individual package 110 below, parts common to the configuration of the individual package 100 of the above-mentioned embodiment are given the same reference numerals, and detailed description will be omitted. In the above-mentioned embodiment, the risk of the cooling agent 26 flowing out of the absorbent article 1 from at least one of the leg openings 1b flowing out of the individual package 100 (packaging material 101) is reduced, but the individual package 110 reduces the risk of the cooling agent 26 flowing out of the absorbent article 1 from the waist opening 1a flowing out of the individual package 110.

13A, in the individual packaging body 110, the left-right direction of the absorbent article 1 is aligned with the folding direction of the packaging material 101, the up-down direction of the absorbent article 1 is aligned with the orthogonal direction perpendicular to the folding direction of the packaging material 101, and the front-rear direction of the absorbent article 1 is aligned with the thickness direction of the packaging material 101. The packaging method of the individual packaging body 110 using the packaging material 101 is generally similar to that of the individual packaging body 100 described above, but the inner joint portion 102 of the individual packaging body 110 is aligned with the left-right direction of the absorbent article 1 (the folding direction of the packaging material 101), and the end joint portions 103a and 103b are aligned with the up-down direction of the absorbent article 1 (the orthogonal direction of the packaging material 101). In other words, the individual packaging body 110 contains the absorbent article 1 in a state in which the folded absorbent article 1 contained in the individual packaging body 100 described above is rotated 90 degrees.

In the individual package 110, similarly to the above-described embodiment, the absorbent article 1 including the cooling agent 26 is packaged in a folded state in which the absorbent article 1 is folded at left and right folding parts LB, RB and top and bottom folding parts BL, in a packaging material 101 including a one-side folding part LC1. The packaging material 101 has an oxygen permeability of 200 cc/ ^m2 /day/atm or less, and the one-side folding part LC1 is aligned along the left-right direction of the absorbent article 1. In addition, the one-side folding part LC1 faces the waist opening 1a of the absorbent article 1.

Since one side folded portion LC1 is aligned along the left-right direction of the absorbent article 1 and faces the waist opening 1a, one side folded portion LC1 of the packaging material 101 having an oxygen permeability of 200 cc/ ^m2 /day/atm or less can cover at least a part of the waist opening 1a, and can therefore act as a lid that reduces the outflow of the cooling agent 26 flowing out from the waist opening 1a to the outside of the individual package 110. By reducing the risk of the cooling agent 26 flowing out from the waist opening 1a flowing out to the outside of the individual package 110, the risk of a decrease in the amount of cooling agent 26 remaining inside the individual package 110 is reduced, making it easier for the wearer to feel the effect of the cooling agent 26 when opening the individual package 110 or wearing the absorbent article 1.

<Individual package 120 in a packaged state according to another embodiment>
An individual packaging body 120 of another embodiment will be described. Fig. 13B is a plan view of the individual packaging body 120 of another embodiment. In the individual packaging body 120 described below, parts common to the configuration of the individual packaging body 100 of the above-mentioned embodiment are given the same reference numerals, etc., and detailed description thereof will be omitted.

In the above embodiment, a part of the folded portion of the one-side extending portion 10L and a part of the folded portion of the other-side extending portion 10R are overlapped in the thickness direction (front-rear direction), but this is not limited thereto. As shown in Fig. 13B, the part of the one-side extending portion 10L folded at the folding reference positions ^B1 and B2 and the part of the other-side extending portion 10R may be folded so as not to overlap in the thickness direction. This reduces the amount of cooling agent 26 that leaks out through the leg openings 1b at the folded portions LC1 and LC2 of the packaging material 101 having an oxygen permeability of 200 cc/m2/day/atm or less, while reducing the thickness of the absorbent article 1 in the folded state, thereby making the individual package 100 more compact.

<<<<Package 200>>>
A plurality of individual packages 100 may be sold and distributed as a package 200 in which the individual packages 100 are contained in a bag 201. Fig. 14A is a schematic perspective view of the package 200. Fig. 14B is a view illustrating the package 200 as viewed from a side surface 200C.

As shown in FIG. 14A, the package 200 has a plurality of individual packages 100, a bag body 201 for storing the plurality of individual packages 100, and a handle portion 202 for carrying the package 200. The package 200 has a top-bottom direction, a left-right direction, and a front-rear direction that are perpendicular to one another. The package 200 is also substantially rectangular in shape, and has a front surface 200A and a back surface 200B that face each other in the front-rear direction, a pair of side surfaces 200C that face each other in the left-right direction, and a top surface 200D and a bottom surface 200E that face each other in the top-bottom direction.

The bag body 201 is a bag-shaped member formed of a sheet-shaped member. It is preferable that the bag body 201 has gas barrier properties and an oxygen permeability of 200 cc/m ² /day/atm or less. As the bag body 201, for example, a sheet member formed of EVOH resin (ethylene-vinyl alcohol copolymer resin), PET (polyethylene terephthalate), aluminum, etc. can be used. In this embodiment, the bag body 201 is formed of a sheet member of PET (polyester).

As described above, the use of the gas barrier bag 201 reduces the risk of the cooling agent 26 leaking out of the individual package 100, while also reducing the risk of the cooling agent 26 leaking out through the bag 201 to the outside even if the cooling agent 26 does leak out of the individual package 100. This makes it easier for the wearer to feel the effect of the cooling agent 26 when opening the package 200 and the individual package 100 or when wearing the absorbent article 1.

It is preferable that the oxygen permeability of the packaging material 101 of the individual packaging body 100 is lower than that of the bag body 201 of the package 200. As described above, the oxygen permeability of the packaging material 101 of the individual packaging body 100 is 2.0 cc/m ² /day/atm, and the oxygen permeability of the bag body 201 of the package 200 is 80 cc/m ² /day/atm. This makes it easier to reduce the amount of cooling agent 26 that flows out from the individual packaging body 100 to the outside than when the oxygen permeability of the packaging material 101 is higher than that of the bag body 201, and not only makes it easier to maintain the cooling agent 26 inside the individual packaging body 100, but also makes it easier to reduce the amount of cooling agent 26 present outside the individual packaging body 100 and inside the bag body 201, and reduces the volatilization of the cooling agent 26, making it easier for the wearer to feel the effect of the cooling agent 26.

In the individual package 100, the left and right ends of the absorbent article 1 in the folded state are covered by the folds LC1 and LC2 of the packaging material 101, whereas the top and bottom ends of the absorbent article 1 in the folded state are joined at the end joints 103a and 103b, so there is a higher possibility that the cooling agent 26 will leak out from the end joints 103a and 103b rather than from the folds LC1 and LC2. In particular, the other side end joint 103b, which has a lower joining strength than the one side end joint 103a, is more likely to allow the cooling agent 26 to leak out through the other side end joint 103b.

In contrast, the individual packaging body 100 has one-side end joint portion 103a and the other-side end joint portion 103b at one end and the other end in the vertical direction of the absorbent article 1, respectively. The joint strength of the one-side end joint portion 103a is higher than the joint strength of the other-side end joint portion 103b. It is preferable that such an individual packaging body 100 is stored so that the vertical direction of the package 200 and the vertical direction of the absorbent article 1 are aligned, and the other-side end joint portion 103b is in contact with the bottom surface of the bag body 201 (bottom surface 200E of the package 200). That is, in this embodiment, as shown in FIG. 14B, two individual packaging bodies 100 are stored in a stacked manner in the vertical direction, the vertical direction of the package 200 and the end joint portions 103a and 103b are perpendicular to each other, and the other-side end joint portion 103b, which has a weaker joint strength than the one-side end joint portion 103a of the individual packaging body 100 stored below, is in contact with the bottom surface 200E.

Because the packaging material 101 is a soft sheet-like member, the portion of the individual packaging body 100 outside the end joints 103a, 103b in the vertical direction is less rigid and softer than the end joints 103a, 103b. Therefore, as shown in FIG. 14B, when the individual packaging bodies 100 are stored so that the vertical direction of the package 200 and the vertical direction of the absorbent article 1 are aligned, the portion of the individual packaging body 100 stored at the bottom of the package 200 below the other end joint 103b is bent in the left-right direction of the package 200 (thickness direction of the individual packaging body 100) due to the weight of the two individual packaging bodies 100, and the other end joint 103b is likely to come into contact with the bottom surface 200E. Even if the joining strength of the other end joint 103b of the individual package 100 is weaker than the joining strength of the one end joint 103a, the other end joint 103b comes into contact with the bottom surface 200E, making it difficult for a gap to form between the other end joint 103b and the bottom surface of the bag body 201, reducing the risk of the cooling agent 26 leaking out of the individual package 100 from the other end joint 103b.

The package 200 has been described as being configured to house multiple individual packages 100, but this is not limited thereto. The package 200 may be configured to house one individual package 100. The package 200 may also be configured to house multiple (or one) individual packages 110.

===Other embodiments===
The above-mentioned embodiment is for the purpose of facilitating understanding of the present invention, and is not intended to limit the present invention. The present invention can be modified or improved without departing from the spirit of the present invention, and it goes without saying that the present invention includes equivalents thereof.

In the above embodiment, the individual package 100 has the packaging material 101 with one side fold LC1 and the other side fold LC2, but this is not limited to this. The individual package 100 may have only one fold, or may have three or more folds. Furthermore, the individual package 100 does not necessarily have to have an inner joint 102, and the inner joint 102 does not necessarily have to be in the center in the orthogonal direction. For example, the inner joint 102 may be provided at the end on the other side in the orthogonal direction.

In addition, in the above-described embodiment, the absorbent article 1 in the folded state is folded at the left and right folding portions LB, RB and the top and bottom folding portions RB, but this is not limited to the above. The absorbent article 1 in the folded state may be, for example, folded at the left and right folding portions LB, RB and not folded at the top and bottom folding portions RB, or folded at the top and bottom folding portions RB and not folded at the left and right folding portions LB, RB. Furthermore, only one of the left and right folding portions LB and the left and right folding portions RB may be folded.

In the above embodiment, the absorbent article 1 is folded in a state in which the length N from the upper and lower folding parts BL to the waist opening 1a in the vertical direction in the individual package 100 in the packaged state is equal to or greater than the length M from the upper and lower folding parts BL to the end of the crotch part 10m (N≧M), but this is not limited to this. In the individual package 100 in the packaged state, the length from the upper and lower folding parts BL to the end of the crotch part 10m in the vertical direction may be longer than the length from the upper and lower folding parts BL to the waist opening 1a (M>N). In this case, it is more preferable that the inner joint part 102 is provided at a position closer to the crotch part 10m than the waist opening 1a in the thickness direction of the individual package 100 (front-rear direction of the absorbent article 1). As a result, the crotch part 10m covers the waist opening 1a, and the waist opening 1a can be sandwiched between the crotch part 10m and the packaging material 101, thereby reducing the risk of the cooling agent 26 leaking out from the waist opening 1a.

In the above embodiment, a cooling stimulant that stimulates the temperature-sensitive TRP channel is used as the cooling agent 26, but this is not limited to this. The cooling agent 26 may be an agent that lowers the surrounding temperature by vaporization heat, for example, alcohol such as methanol or ethanol.

In the above embodiment, the cooling agent 26 is used as an example of a volatile substance, but the volatile substance is not limited to the cooling agent 26, and may be, for example, a warming agent, a fragrance, or other volatile substance. The fragrance may be used instead of the cooling agent 26, or may be used together with the cooling agent 26 or the warming agent.

When a fragrance with a green herbal scent (green herbal-like aroma) is used as the fragrance, it becomes possible to safely and easily relieve mental discomfort without causing physical irritation to the body and without the need for oral administration. In addition, a sense of comfort is also achieved.

When a warming agent is used, it is possible to alleviate the wearer's menstrual pain and cold symptoms. From the viewpoint of the wearer's sense of security, it is preferable that the warming agent is a compound derived from a plant. Examples of warming agents include capsicoside, capsaicin (LD50: 47 mg/kg, molecular weight: 305), capsaicinoids (dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, nonivamide, etc.), capsanthin, benzyl nicotinate (LD50: 2,188 mg/kg, molecular weight: 213), β-butoxyethyl nicotinate, N-acyl vanillamide, vanillyl amide nonanoate, polyhydric alcohols, chili pepper powder, chili pepper tincture, chili pepper extract, vanillyl ether nonanoate, vanillyl alcohol alkyl ether derivatives (e.g., vanillyl ethyl ether, vanillyl butyl ether ( LD50: 4,900 mg/kg, molecular weight: 210), vanillyl pentyl ether, vanillyl hexyl ether), isovanillyl alcohol alkyl ether, ethyl vanillyl alcohol alkyl ether, veratorial alcohol derivatives, substituted benzyl alcohol derivatives, substituted benzyl alcohol alkyl ether, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, ginger extract, ginger oil, gingerol (LD50: 250 mg/kg, molecular weight: 294), zingerone, hesperidin, and pyrrolidone carboxylic acid, and any combination thereof. Note that, as with the cooling agent 26, the warming agent is preferably one that stimulates a temperature-sensitive TRP channel.

The fragrance may be the same as that which has been conventionally used in the relevant technical field. When a green herbal fragrance (green herbal-like scent) is used as the fragrance, it becomes possible to alleviate mental discomfort safely and easily without causing physical stimulation to the body and without the need for oral administration. In addition, a sense of comfort is also obtained.

A green herbal-like aroma is an aroma that includes a green-like aroma (green note) or a herbal-like aroma (herbal note). A green-like aroma is a refreshing aroma of grass or young leaves. A herbal-like aroma (herbal note) is an aroma that is natural and characterized by a medicinal fragrance using herbs.

The fragrance composition containing fragrances having a green herbal-like scent is cis-3-hexenol, cis-3-hexenyl formate, cis-3-hexenyl acetate, cis-3-hexenyl propionate, cis-3-hexenyl butyrate, trans-2-hexenal, trans-2-hexenyl acetate, hexyl acetate, styraryl acetate, 2-methyl-3-(3,4-methylenedioxyphenyl)-propanal (IFF brand, Helional), 3(4)-(5-ethylbis(2-methyl-1,2-propanol), ... It is preferable to contain one or more fragrances selected from chloro[2,2,1]heptyl-2)-cyclohexanol, allyl 2-pentyloxyglycolate (Allyl Amyl Glycolate, IFF), 4-methyl-3-decen-5-ol (Undecabertol, Givaudan), hexylaldehyde, 2,4-dimethyl-3-cyclohexenylcarboxaldehyde (Tripral, IFF), and phenylacetaldehyde. Commercially available products can also be used as these fragrances. The fragrances that contain these mainly produce a green-like odor.

The fragrance composition containing a fragrance having a green herbal-like odor preferably further contains one or more fragrances selected from l-menthol, 1,8-cineole, methyl salicylate, citronellal, camphor, borneol, isobornyl acetate, terpinyl acetate, eugenol, anethole, 4-methoxybenzyl alcohol, and estragole. Fragrances containing these primarily produce an herbal-like odor.
