The "inside of the absorbent article 1" means the side closer to the skin than the outermost sheet of the absorbent article 1, that is, the outer back sheet 12. In the present embodiment, it is applied to the non-skin side of the first skin-side sheet 24a, as shown in FIG. 3, in the central part of the absorber 22 in the left-right direction, excluding the region of both side end parts, and is absorbed throughout the absorption The coating region 26P is provided over the entire region in the longitudinal direction of the body 22 . In particular, it is preferable to provide the cooling agent 26 in the center portion in the left-right direction of the absorber 22 so as to come into contact with the excretory opening (vaginal opening) of the wearer during wearing. In this embodiment, although the application area|region 26P is provided in the 1st skin side sheet|seat 24a, it is not limited to this, If it is the inner side of the absorbent article 1, it can arrange|position arbitrarily. 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 on the absorbent body 20. Moreover, it is more preferable that the cooling agent 26 is provided in the non-skin side of the 1st skin-side sheet 24a. At this time, in the absorbent article 1, it is preferable that the amount of the cooling agent 26 held by the first skin-side sheet 24a is larger than the amount of the cooling agent 26 held in the side sheet 24d. Since the first skin-side sheet 24a is a member of the absorbent body 20 that is located close to the wearer's skin during wearing, the wearer can easily feel the cool feeling provided on the first skin-side sheet 24a. Efficacy of Agent 26. In addition, by reducing the amount of the cooling agent 26 held by the side sheet 24d, it is possible to reduce the risk of lowering the adhesiveness of adhesives such as hot melt adhesive for fixing the elastic member 50S to the side sheet 24d.

The cooling agent 26 is a substance for reducing discomfort such as stuffiness and stickiness of the wearer, and has a cooling sensation stimulant that stimulates the wearer's sense of temperature. The cooling sensation stimulant of the present embodiment employs a substance capable of producing a cooling sensation effect in the installed state. For example, in a state where excretion such as urine and menstrual blood is excreted and the absorbent body 20 absorbs the excrement, the wearer is likely to feel the discomfort caused by the excrement and is less likely to feel the effect of the cooling agent 26 . On the other hand, the cooling sensation stimulant used in the cooling sensation agent 26 of the present embodiment does not react with the moisture contained in the excrement to exert its effect, but uses the time from when the wearer wears the absorbent article 1 By clicking on the substance that can obtain the cooling effect, the wearer can easily feel the effect of the cooling agent 26 and easily obtain the comfortable feeling produced by the cooling agent 26 . Since the cooling agent 26 provided in the absorbent article 1 is applied in a state of being mixed with a volatile solvent, it has high volatility.

From the viewpoint of the safety of the wearer, the cooling sensation stimulant is preferably derived from a plant. Examples of cooling sensation stimulants include menthol (for example, L-menthol, etc.) and menthol derivatives (for example, menthyl lactate, menthyl glyceryl ether, etc.); methyl salicylate; Essential oils of plants such as eucalyptus, etc.

The cooling sensation stimulator of the cooling sensation agent 26 is preferably one that stimulates the temperature-sensitive TRP channel. For example, in one of the temperature-sensitive TRP channels, TRPM8 is the cool stimulus receptor of the cool sensor. Menthol (e.g. L-menthol) and its derivatives (e.g. menthyl lactate), etc., by activating TRPM8, in fact, even if the temperature does not drop, it also makes the cool sensor respond, therefore, it can be used for the wearer. Gives a cooling sensation. That is, it is preferable to make the wearer feel cool, rather than lowering the temperature by absorbing heat by itself. Therefore, the wearer can feel a cooling sensation without overcooling the skin.

Moreover, since the cooling agent 26 is in direct contact with the wearer's skin, its effect is easily exhibited. For example, a volatile substance such as a fragrance exhibits an effect of suppressing surrounding odors when it becomes a gas, but the cooling agent 26 directly contacts the wearer's skin after being vaporized, and exerts its main effect. That is, the cooling agent 26 is brought into contact with the wearer's skin via the nonwoven fabric (the first skin-side sheet 24a) or the like, whereby the wearer can gradually feel the effect of the cooling agent 26 on the skin.

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

Examples of the lipophilic solvent include oils and fats, such as natural oils (eg, fatty acid esters such as triglycerides, coconut oil, linseed oil, tri(caprylic/capric) glycerides, etc.), hydrocarbons (eg Paraffin wax such as flowing paraffin) and so on.

Moreover, as a hydrophilic solvent, water and alcohol are mentioned. Examples of the alcohols include lower alcohols such as methanol, ethanol, ethylene glycol, and glycerin, and higher alcohols such as octanol, lauryl alcohol, and myristyl alcohol.

Moreover, in the packing state, the packaging material 101 has: a bending direction along the bending parts LC1 and LC2 (described later); an orthogonal direction orthogonal to the bending direction; and a thickness direction which is orthogonal to the bending direction and Orthogonal. In the individual packaging body 100 in the packaged state, the bending direction of the packaging material 101 is along the vertical direction of the individual packaging body 100 and the absorbent article 1, and the orthogonal direction of the packaging material 101 is along the individual packaging body 100 and the absorbent article. 1, the thickness direction of the packaging material 101 is along the thickness direction of the individual package 100 and the front-rear direction of the absorbent article 1.

<Absorbent article 1 in a folded state> The absorbent article 1 in the folded state refers to the state in which the absorbent article 1 in the unfolded state is folded by the folded portions along the up-down direction and the left-right direction. Fig. 6 is a schematic view of the absorbent article 1 in the unfolded state viewed from the back side. For the convenience of description, in FIGS. 6 to 12 , one side leg opening 1 b is shown by a slanted line obliquely downward to the left.

The absorbent article 1 (refer to FIG. 8 ) in the folded state is formed by folding at the folding reference positions B1 , B2 , and B3 from the unfolded state shown in FIG. 6 . The folding reference positions B1 , B2 , and B3 are positions that serve as references (fulcrums) when the absorbent article 1 is folded, respectively. In the absorbent article 1 (individual package 100 ), first, from the unfolded state shown in FIG. 6 , the folding reference positions B1 and B2 are respectively folded inward in the left-right direction. The folding reference position B1 is a reference position for folding in the up-down direction, and is provided at an arbitrary portion of the one-side extension portion 10L. The folding reference position B2 is a reference position for folding in the up-down direction, and is provided at an arbitrary portion of the other side extension portion 10R. The folding reference position B3 is a reference position for folding in the left-right direction, and is provided on the lower side (crotch side) of the center in the vertical direction of the absorbent article 1 in the unfolded state.

From the unfolded state shown in FIG. 6 , first, the portion of the extension portion 10L on the one side that is outside of 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 secondly , and then fold the portion outside the folding reference position B2 in the left-right direction of the extension portion 10R on the other side toward the back side to form the state shown in FIG. 7B . Fig. 7A is a diagram showing a state in which the absorbent article 1 of Fig. 6 is folded at the folding reference position B1. Fig. 7B is a diagram showing a state in which the absorbent article 1 of Fig. 7A is 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 in the extension part 10L on one side and a part of the folded part in the extension part 10R on the other side are folded in the thickness direction (front-rear direction). ) overlapped. Thereby, the length in the left-right direction of the absorbent article 1 in the folded state can be further shortened. In addition, the one side extension part 10L and the other side extension part 10R may be folded first.

Furthermore, at the folding reference position B1 and the folding reference position B2 shown in FIGS. 7A and 7B , the part of the extension part 10L on one side and the part of the extension part 10R on the other side are respectively folded ( FIG. 7B ), When the absorbent article 1 is viewed from the upper side (for example, the back side) in the thickness direction (front-rear direction), the end on one side in the left-right direction is referred to as [one side folded part LB], and the end on the other side in the left-right direction is called It is called "the other side folded part RB", and the one side folded part LB and the other side folded part RB are also called "left and right folded parts". The one side folded portion LB and the other side folded portion RB are respectively along the vertical 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 positioned outside the folding reference position B1 and the folding reference position B2 in the left-right direction, respectively. In the unfolded state, one side folded portion LB overlaps with the folding reference position B1 in the front-rear direction (thickness direction), and the other side folded portion RB overlaps with the folding reference position B2 in the front-back direction (thickness direction). In addition, in this Embodiment, although [the left-right folded part LB, RB along an up-down direction] was demonstrated as being parallel to the up-down direction of the absorbent article 1, it is not limited to this. The left and right folded portions LB and RB along the vertical direction may be inclined within a range of 45 degrees with respect to the vertical direction, respectively.

Next, the absorbent article 1 in the state shown in FIG. 7B is formed by folding the portion on the lower side (crotch side) from the folding reference position B3 in the up-down direction to the upper side (the waist opening 1a side). The absorbent article 1 in the folded state shown in FIG. 8 . FIG. 8 is a diagram showing the absorbent article 1 in a folded state. When the absorbent article 1 in the folded state in which the absorbent article 1 is folded in the up-down direction along the folding reference position B3 in the left-right direction is viewed from the upper side in the thickness direction, the end at the lower end in the up-down direction is called. [Up and down folding part BL]. The up-down folding part BL is along the left-right direction. Since the absorbent article 1 has a predetermined thickness, the vertically folded portion BL in the folded state is positioned above the folding reference position B3 (the waist opening portion 1a side) in the vertical direction. Moreover, in this Embodiment, although the "up-and-down folded part BL along the left-right direction" was demonstrated as being parallel to the left-right direction of the absorbent article 1, it is not limited to this. The up-and-down folded portion BL may be inclined within a range of 45 degrees with respect to the left-right direction, respectively. Furthermore, in the unfolded state, the upper and lower folded portions BL overlap with the folding reference position B3 in the front-rear direction (thickness direction). Moreover, as shown in FIG. 3, in the unfolded state, it is preferable to set the folding reference position B3 so that it may become orthogonal to the up-down direction of the absorber 22. Moreover, you may provide so that the folding reference position B3 may cross|intersect the press part 40 provided in the absorptive main body 20. The absorber 22 is a member with high rigidity in the absorbent article 1 . Similarly, the press part 40 is a part with higher rigidity in the absorbent article 1 . By folding at the portion intersecting with the high-rigid press section 40, so-called folds are easily formed in the absorber 22, and the folded state of the absorbent article 1 is easily maintained. The cooling agent 26 on the inner side of 1 may volatilize through the waist opening 1a.

<The packing method by the packing material 101> A method of packaging the folded absorbent article 1 with the packaging material 101 will be described. FIG. 10 is a diagram showing the state of the first packaging process. In the first packaging process, as shown in FIG. 10 , the packaging material 101 having a larger size and a rectangular shape than the absorbent article 1 in the folded state is unfolded horizontally, and the absorbent article 1 in the folded state is placed on the packaging. approximately the center of the material 101. At this time, in the absorbent article 1 in the folded state, in the thickness direction (front-rear direction), the side of the waist opening 1a (waist parts 10f, 10b) is the side (lower side) in contact with the packaging material 101, and the crotch part 10m side as the upper side. Furthermore, the first bending reference position L1 shown in FIG. 10 is a reference position for folding the packaging material 101 in the second packaging process, and the second bending reference position L2 is used for the third packaging process. The process folds the packaging material 101 to the reference position. At this time, the first bending reference position L1 and the second bending reference position L2 are set along the vertical direction of the absorbent article 1 .

The packaging material 101 can reduce the risk of the cooling agent 26 included in the absorbent article 1 flowing out to the outside of the individual package 100 by using a material that does not easily allow volatile substances such as the cooling agent 26 to permeate (so-called high gas barrier properties). . As the packaging material 101 that does not easily allow permeation of volatile substances, a sheet member having an oxygen permeability in the thickness direction of 200 cc/m ² /day/atm or less at 23° C. is used. The permeability of volatile substances in the thickness direction of the packaging material 101 is slightly proportional to the oxygen permeability. Therefore, the oxygen permeability in the thickness direction of the packaging material 101 is used to define the amount of volatile substances that pass through the thickness direction of the packaging material 101. degree.

As the packaging material 101, 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 can be used. The packaging material 101 of the present embodiment is a sheet of a film material comprising a multi-layered PE/admer/EVOH/admer/PE of EVOH resin (ethylene-vinyl alcohol copolymer resin), and the oxygen permeability is 2.0 cc/m ² /day/atm. The oxygen permeability of the packaging material 101 can be measured, for example, by a known method such as a Coulometric method (MOCON method) under conditions of 23° C. and 0% RH.

Specifically, first, filter paper impregnated with menthol, which is a cooling agent 26, and packaging material 101 made of EVOH resin are prepared, and the weights of the filter paper and packaging material 101 are measured. Next, the weight of Sample A in a state where the menthol-containing filter paper was placed on the packaging material 101 made of EVOH resin, folded in three, and sealed with a sealing member was measured. The weight of the menthol contained in the filter paper was obtained by subtracting the weight of the menthol-free filter paper and the weight of the packaging material 101 from the weight of the sample A in this state. Then, after a predetermined period of time has elapsed under predetermined conditions (for example, 1 week and 4 weeks have elapsed in the state of being placed in a constant temperature and humidity machine at 40°C and 70%), the weight of the sample A is measured, and the weight of the sample A is calculated. With the reduced weight, the outflow of menthol as the cooling agent 26 was obtained. Moreover, the reduction rate of menthol can be calculated by comparing the weight of menthol after the lapse of a predetermined time and the weight of menthol before the lapse of a predetermined time. In addition, it is preferable to measure the outflow amount of menthol and the like for a predetermined number of times (for example, 10 times), and to obtain the average value.

Similarly, for Sample B in which the menthol-containing filter paper was placed on a sheet made of PET, folded in three, and sealed with a sealing member, the menthol-containing filter paper was placed on a polyvinyl chloride (PVC) sheet. Sample C in the state of being sealed with the sealing member and folded in three on the sheet, and the filter paper containing menthol is placed on the sheet composed of PE (polyethylene), folded in three, and sealed with the sealing member. For the samples D, the outflow amount of menthol as the cooling agent 26 can be obtained by the same method, respectively. In addition, the size of the filter paper and the size of the sheet of each sample were made the same.

Fig. 9 is a graph showing the measurement results of the outflow amount of menthol. In FIG. 9, the average value is shown for each weight and ratio, respectively. The weight of menthol at the start of measurement of sample A (EVOH resin, packaging material 101) was 0.5 g, the weight of menthol after 1 week was reduced by 2% from the start of measurement, and the weight of menthol after 4 weeks Weight is a 2% reduction from the start of the measurement. The weight of menthol at the start of the measurement of Sample B (sheet made of PET) was 0.5 g, the weight of menthol at the start of the measurement was 0.5 g, and the weight of menthol after 1 week was reduced by 2 from the start of the measurement. %, the weight of menthol after 4 weeks was reduced by 2% from the start of the measurement. The weight of menthol at the start of the measurement of sample C (sheet made of PVC) was 0.5 g, the weight of menthol after 1 week was reduced by 6% from the start of measurement, and the weight of menthol after 4 weeks It is a 10% reduction from the start of the measurement. The weight of menthol at the start of the measurement of sample D (sheet composed of PE) was 0.5 g, the weight of menthol after 1 week was reduced by 32% from the start of measurement, and the weight of menthol after 4 weeks is a 98% reduction from the start of the measurement.

The oxygen permeability of the sheet members used in Samples A to D was 2.0 cc/m ² /day/atm for the sheet made of EVOH resin, 80 cc/m ² /day/atm for the sheet made of PET, and The sheet composed of PVC is 200 cc/m ² /day/atm and the sheet composed of PE is 7900 cc/m ² /day/atm.

The weights of the cooling agents 26 before the predetermined time elapsed in the samples A to D are compared with the weights of the cooling agents 26 after the predetermined time, and if the reduction rate of menthol is 10% or less, the wearer should wear It is assumed that the cooling agent 26 can be easily recognized at the lower part of the crotch (the part in contact with the absorptive main body 20). Regarding the weights of the cooling agents 26 after 4 hours of samples A to D, the following results were obtained. That is, the sheets made of EVOH resin with an oxygen permeability of 200 cc/m ² /day/atm or less were made of PET. A sheet made of aluminum, a sheet made of aluminum, and a sheet made of PVC each had a predetermined weight of menthol remaining, while the sheet made of PE with an oxygen permeability higher than 200cc/m ² /day/atm, Almost no menthol remains. In addition, in the sheet made of EVOH resin, the sheet made of PET, and the sheet made of PVC, the change in the value of the reduction rate of menthol after 1 week and after 4 weeks was small. In the sheet, the value of the reduction rate of menthol after 1 week and after 4 weeks changed greatly, so that the menthol flowed out through the PE sheet with the passage of time.

From the results of the outflow amount of the cooling agent 26 of the samples A to D, it was found that when a sheet (sample C) made of PVC with an oxygen permeability of 200 cc/m ² /day/atm was used as the packaging material 101 , the The gas barrier property which can feel the effect of the cooling agent 26, and when the sheet (Sample D) made of PE is used as the packaging material 101, does not have the gas barrier property which can feel the effect of the cooling agent 26. Therefore, the packaging material 101 is preferably a sheet member having an oxygen permeability in the thickness direction of 200 cc/m ² /day/atm or less.

At the bending reference position L1, the packaging material 101 is turned so that the first folded portion 101L on one side in the left-right direction of the packaging material 101 faces the other side in the left-right direction, and the first folded portion 101L is covered with the folded state. The absorbent article 1 is folded so as to be on the side of the crotch portion 10m, and is in the state of the second packaging process as shown in FIG. 11 . FIG. 11 is a diagram showing the state of the second packaging process. In FIG. 11, the folded 1st folded-back part 101L is shown by the slanted line part inclined downward to the left. As shown in FIG. 11 , in the second packaging process, by setting the bending reference position L1 as the end of one side in the left-right direction of the absorbent article 1, one side of the left-right direction can be made into the absorbent article 1 A state in which there is almost no gap (small gap) with the packaging material 101 . Moreover, the individual package 100 (packaging) is viewed from the upper side (for example, the back side) in the thickness direction (front-rear direction of the absorbent article 1 ) in a state where the first folded portion 101L is folded at the folding reference position L1. In the case of the individual package body 100) on the way, the end on one side in the left-right direction is referred to as [one side bent portion LC1].

In the second packaging process, an adhesive 101h such as a hot-melt adhesive is applied to the end portion on the other side in the left-right direction of the outer surface of the first folded portion 101L. The adhesive 101h is used to join the first folded portion 101L and the second folded portion 101R to form the joining portion of the joining portion 102 . This adhesive 101h is placed on the upper and lower sides of the absorbent article 1 in order to prevent foreign matter from entering the inside of the individual package 100 or to reduce the risk of the cooling agent (volatile substance) 26 provided in the absorbent article 1 flowing out of the individual package 100. It is preferable to apply continuously from the upper end to the lower end of the packaging material 101 in the direction. In addition, since the adhesive 101h can bond the outer surface of the first folded portion 101L and the inner surface of the second folded portion 101R, the adhesive 101h may not be provided on the outer surface of the first folded portion 101L. , instead, the adhesive agent 101h is provided on the inner surface of the second folded portion 101R.

Next, the packaging material 101 is bent at the reference position L2 so that the second folded portion 101R on the other side in the left-right direction of the packaging material 101 faces the one side in the left-right direction from the crotch portion of the absorbent article 1 in the folded state. The side of the end of 10 m was folded so that the 1st folded part 101L and the 2nd folded part 101R may be covered, and it was set as the state of the 3rd packaging process as shown in FIG. 12. FIG. 12 is a diagram showing the state of the third packaging process. In FIG. 12 , the folded second folded-back portion 101R is shown by the shaded portion slanted diagonally downward to the right. As shown in FIG. 12 , in the third packaging process, by setting the bending reference position L2 as the end of the other side in the left-right direction of the absorbent article 1, the other side in the left-right direction can be made in the absorbent article 1. A state in which there is almost no gap (small gap) between the article 1 and the packaging material 101 . Moreover, the individual package 100 (packaging) is viewed from the upper side (for example, the back side) in the thickness direction (front-rear direction of the absorbent article 1 ) in a state in which the second folding portion 101R is folded at the folding reference position L2 In the case of the individual package body 100) in the middle, the end of the other side end in the left-right direction is referred to as [the other side bent portion LC2].

In the third packaging process, the end portion on the other side of the left-right direction of the first folded portion 101L and the end portion on the one side of the left-right direction of the second folded portion 101R are overlapped at the approximate center in the left-right direction. , and are joined by the adhesive 101h provided on the outer surface of the first folded portion 101L in the second packaging process, thereby forming the inner joining portion 102 . That is, the inner joint portion 102 is a joint portion formed by the adhesive 101h. The inner joint portion 102 is continuous along the one side bent portion LC1 and the other side bent portion LC2 along the vertical direction, from one end to the other end in the vertical direction. Moreover, the inner joint part 102 is provided in the left-right direction (orthogonal direction) more inside than the one side bending part LC1, and is provided more inside than the other side bending part LC2. That is, the inner joint portion 102 is provided between the one side bent portion LC1 and the other side bent portion LC2 in the left-right direction, and is provided in the approximately center portion in the orthogonal direction in the individual package 100 . By the third packaging process, the packaging material 101 is provided with, in the thickness direction, a surface on which the inner junction portion 102 is not provided, and a surface on which the inner junction portion 102 is provided.

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

Finally, in the fourth packaging process, a pair of end joints 103 are formed. The one side edge part junction part 103a and the other side edge part junction part 103b are respectively formed in the edge part on one side and the edge part on the other side of the up-down direction (orthogonal direction) of the packaging material 101. The one side end portion joint portion 103a and the other side end portion joint portion 103b are joint portions formed by welding to which heat and pressure are applied, respectively. The one side end joint portion 103a and the other side end portion joint portion 103b are preferably continuous along the left-right direction (orthogonal direction) from one end to the other end in the left-right direction. The absorbent article 1 is formed in the state accommodated in the packaging material 101 by formation of a pair of edge part joint part 103, and becomes the individual packaging body 100 as shown in FIG.

<Individual package body 100 in a packaged state> The individual package 100 of the absorbent articles 1 such as sanitary napkins is desired to have a compact shape for reasons of portability and the like, and it is desired that the wearer can feel that the package is taken out of the compact shape when wearing it. Effects of volatile substances such as the cooling agent 26 of the absorbent article 1 . Volatile substances such as the cooling agent 26 provided on the inside of the absorbent article 1 easily flow out to the outside of the absorbent article 1 from the waist opening 1a, the foot opening 1b, etc. opened as [openings].

The individual package 100 is a folded state in which the absorbent article 1 provided with the cooling agent 26 is folded with the left and right folded parts LB and RB along the vertical direction, and the vertical folded part BL along the left and right direction, so as to have one side bend. The packaging material 101 of the folded portion LC1 is packaged. This packaging material 101 has an oxygen permeability of 200 cc/m ² /day/atm or less, and one side folded portion LC1 is along the vertical direction of the absorbent article 1 .

Generally, in the underpants-type absorbent article, the leg openings 1b are provided on both outer sides in the left-right direction orthogonal to the vertical direction. Therefore, in the left-right direction, the folded portion LC1 on one side of the packaging material 101 located on the outer side of the absorbent article 1 is along the vertical direction of the absorbent article 1, and the oxygen permeability can be made to be 200 cc/m ² / The one-side folded portion LC1 of the packaging material 101 of less than day/atm covers at least a part of the one side of the foot opening 1b in the left-right direction, and thus can be used as a cooling agent for reducing flow out from the one side of the foot opening 1b 26 The lids that flow out to the outside of the individual packages 100 function.

If there is a junction part for joining the packaging materials 101 along the vertical direction on one side of the absorbent article 1 in the left-right direction, the cooling agent 26 may flow out from the gap of the junction part. On the other hand, in the case of the absorbent article 1, one side folded portion LC1 of the packaging material 101 having an oxygen permeability rate of 200 cc/m ² /day/atm or less and no seams is formed along the vertical direction of the absorbent article 1 . And it is provided in one side rather than the absorbent article 1, and it can reduce the possibility that the cooling agent 26 which flows out from the leg opening part 1b of one side flows out to the outside of the individual package 100. By reducing the risk of the cooling agent 26 flowing out from the one side of the leg opening 1b to the outside of the individual package 100, it is possible to reduce the risk of decreasing the amount of the cooling agent 26 inside the individual package 100, and it can be worn. The user is likely to feel the effect of the cooling agent 26 when opening the individual package 100, when wearing the absorbent article 1, or the like.

Moreover, as the absorbent article 1 in the folded state, the one side folded portion LC1 along the vertical direction is provided on one side of the absorbent article 1 in the left-right direction. In the case where a joint portion for joining the packaging materials 101 in the vertical direction is provided on one side of the absorbent article 1, the length of the individual packaging body 100 in the left-right direction can be shortened, and the individual packaging body 100 can be Made into a tighter shape. That is, the difference between the length in the left-right direction of the absorbent article 1 in the folded state and the length in the left-right direction of the individual package 100 can be further shortened. At this time, the absorbent article 1 in the packaged state (folded state) is preferably in contact with the packaging material 101 on at least one of the one side or the other side in the left-right direction.

In addition, the cooling agent 26 contains a volatile solvent and is vaporized in the state containing the cooling stimulant, so the vaporization of the cooling agent 26 may be accelerated due to external stimulation, circulation of outside air, and the like. On the other hand, by making the individual package 100 into a compact shape, and by further shortening the difference between the length in the left-right direction of the absorbent article 1 in the folded state and the length in the left-right direction of the individual package 100, the Inside the package body 100, the movement of the absorbent article 1 to the package body 101 can be reduced. As a result, the vaporization of the cooling agent 26 can be easily reduced, and the effect of the cooling agent 26 can be easily felt by the wearer. In addition, "outflow" of the cooling agent 26 includes not only the outflow in the liquid or solid state of the cooling agent 26, but also the outflow in the state where the cooling agent 26 is vaporized.

Since the absorbent article 1 has the pair of leg openings 1b that form openings on both sides in the left-right direction, and the packaging material 101 includes not only one side bending part LC1 but also the other side bending part LC2, it is possible to reduce the need for The cooling agent 26 flowing out of the foot opening 1b on one side in the left-right direction of the absorbent article 1 flows out to the outside of the individual package 100, and similarly, the foot opening from the other side in the left-right direction can be reduced. The cooling agent 26 flowing out of the part 1b flows out to the outside of the individual package 100 again. Therefore, the wearer is more likely to feel the effect of the cooling agent 26 when the individual package 100 is unsealed, when the absorbent article 1 is worn, or the like. In addition, since the individual package 100 has a shape that is slightly symmetrical with respect to the left-right direction (orthogonal direction), the features of the one-side bent portion LC1 are the same as those of the other-side bent portion LC2, and detailed descriptions which will be described later will be omitted. .

In the absorbent article 1 in the unfolded state and in the natural state, the cooling agent 26 is preferably provided on the crotch side of the crotch rather than the vertically folded portion BL in the vertical direction. In FIG. 3, the position corresponding to the vertical folded part BL of the absorbent body 20 of the absorbent article 1 in the unfolded state and the natural state is shown. The cooling agent 26 provided in the upper and lower folded parts BL of the absorbent article 1 in the unfolded state and in the natural state is closer to the crotch side. In the folded state, the cooling agent 26 is located between the upper and lower folded parts BL and the crotch part 10m. Since the cooling agent 26 may flow out to the outside of the absorbent article 1, the cooling agent 26 flowing out to the outside of the individual package 100 can be further reduced.

Moreover, in the absorbent article 1 in the unfolded state and the natural state, the cooling agent 26 is preferably provided on the inner side of the left and right folded parts LB and RB provided on the outside of the absorber 22 in the left-right direction. As shown in FIG. 6 etc., since the left and right folded parts LB and RB of the absorbent article 1 are located in the left-right direction and are located outside the absorptive main body 20, they are clearly located outside the absorber 22. In the absorbent article 1 in the folded state, the cooling agent 26 provided on the inner side of the left and right folded parts LB and RB in the left-right direction is folded at the left and right folded parts LB and RB, so that the cooling agent 26 can be reduced from the foot. The outflow path surrounding the opening 1b can reduce the risk of the cooling agent 26 flowing out to the outside of the absorbent article 1 , and can reduce the cooling agent 26 flowing out to the outside of the individual package 100 .

As shown in FIG. 5 etc., the individual package body 100 in a packaged state has the edge part joint part 103 along the left-right direction (orthogonal direction). As described above, in order to make the individual package 100 in a sealed state, the end joints 103a and 103b where the packaging materials 101 are joined to each other are provided at both ends in the up-down direction (folding direction). Inside the packaging material 101 of the individual package 100, when the absorbent article 1 is placed in the center in the vertical direction of the individual package 100, the longest distance between one side folded portion LC1 and the absorbent article 1 is It is preferable that the longest distance between the end joint portion 103a (or 103b ) and the absorbent article 1 is shorter. For example, as shown in FIG. 5 , when the absorbent article 1 is placed in the center portion in the vertical direction of the individual package 100 inside the individual package 100 , one side folded portion LC1 is connected to the absorbent article 1 . The longest distance with respect to the left-right direction is shorter than the longest distance X with respect to the vertical direction between the end joint portion 103a (or 103b ) and the absorbent article 1 . In the present embodiment, the end joint portions 103a (103b) are separated from the absorbent article 1 by a predetermined distance (the longest distance X) in the up-down direction, and on the other hand, in the left-right direction, one side bent portion LC1 is connected to the absorbent article 1. When the article 1 is in contact with or approached, the distance between the one side bent portion LC1 and the absorbent article 1 is extremely short and close to zero. Therefore, when the absorbent article 1 is already arranged in the center portion in the vertical direction of the individual package 100, the longest distance between the one side folded portion LC1 and the absorbent article 1 is significantly longer than that between the end joint portion 103a and the absorbent article 103a. The longest distance to item 1 is X short. Thereby, compared with the case where the longest distance between the one side bent 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, it is possible to further narrow the one side in the left-right direction. The space between the bent portion LC1 and the absorbent article 1 can further reduce the circulation of the air that promotes volatilization of the cooling agent 26, and can flow out from the absorbent article 1 through the leg opening 1b into the packaging material 101. The amount of the cooling agent 26 is reduced, and it becomes easy to reduce the amount of the cooling agent 26 flowing out to the outside of the packaging material 101 (individual package 100 ).

5 etc., when the case where the absorbent article 1 is arranged in the center in the vertical direction of the individual package 100 is described, the longest distance between the one side folded portion LC1 and the absorbent article 1 is the upper end. Although the longest distance X between the joint part 103a (103b) and the absorbent article 1 is short, even when the absorbent article 1 is arranged at any position in the vertical direction of the individual package 100, one can be The longest distance between the side bending portion LC1 and the absorbent article 1 is made shorter than the longest distance X between the end joint portion 103a (103b) and the absorbent article 1, which can reduce the penetration of the absorbent article 1 through the leg opening portion 1b In addition, the amount of the cooling agent 26 flowing out into the packaging material 101 can be easily reduced in the amount of the cooling agent 26 flowing out to the outside of the packaging material 101 (individual packaging body 100 ).

As described above, the absorbent article 1 of the individual package 100 in the packaged state is in a folded state in which the upper and lower folded parts BL and the left and right folded parts LB and RB are folded. In addition, the individual package 100 in the packaged state has an inner joint portion 102 provided on the inner side of the one side bent portion LC1 (the other side bent portion LC2 ) in the left-right direction (orthogonal direction). The inner joint portion 102 is along the up-down direction (folding direction). The inner joint portion 102 is preferably provided at a position closer to the crotch portion 10 m than the waist opening portion 1 a in the front-rear direction of the absorbent article 1 . That is, as described above (refer to FIGS. 10 to 12 ), the packaging material 101 has, in the thickness direction, a surface on which the inner joint portion 102 is not provided, and a surface on which the inner joint portion 102 is provided, and no inner joint is provided. The surface of the part 102 is located on the side of the waist parts 10f and 10b, and the surface provided with the inner joint part 102 is preferably located at a position close to the crotch part 10m.

Usually, in the underpants-type sanitary napkin (pants-type absorbent article) such as the absorbent article 1, the absorber 22 is provided in the crotch portion 10 m in order to absorb excrement. Generally, the rigidity of the absorber 22 is higher than the part (waist part 10f, 10b) in which the waist opening part 1a is provided. Therefore, by providing the inner joint portion 102 at a position close to the crotch portion 10 m in the thickness direction, the inner joint portion 102 can be formed in a more stable state, and the joint strength of the inner joint portion 102 can be easily improved. In addition, by providing the waist opening 1a in the vicinity of the surface where the inner joint 102 is not provided in the thickness direction, the cooling agent 26 flowing out from the waist opening 1a can be reduced to flow out to the individual package 100 through the inner joint 102 external dangers.

Moreover, as shown in FIG. 5 etc., in the individual package body 100 in a packaged state, the length N from the up-down folded portion BL to the waist opening portion 1a (the upper end of the absorbent article 1 in the natural state) in the up-down direction is from The absorbent article 1 is preferably in a folded state in a state where the length M or more (N≧M) from the vertically folded portion BL to the end of the crotch portion 10m (the lower end of the absorbent article 1 in the natural state) is greater than or equal to the length M (N≧M). By folding in the up-down direction, the leg opening 1b can be covered in a wider range and more reliably by the part closer to the waist opening 1a than the up-down folded part BL. Therefore, it is possible to reduce the possibility that the cooling agent 26 will flow out from the foot circumference opening 1b.

For the individual package 100, it is preferable that the bonding strength of the packaging materials 101 of the inner joint part 102 is higher than the joint strength of the packaging materials 101 of the one side end joint part 103a and the other side end joint part 103b. For the individual package 100 before unsealing, the bonding strength of the one side end joint part 103a or the other side end joint part 103b is lower than the joint strength of the inner side joint part 102, and therefore, compared with the end part joint parts 103a, 103b When the bonding strength is higher than the bonding strength of the inner bonding portion 102, the wearer can easily separate the bonding and separation of the packaging materials 101 of the end bonding portions 103a and 103b. In addition, by making the joint strength of the inner joint part 102 higher than the joint strength of the end joint parts 103a and 103b, compared with the case where the joint strength of the inner joint part 102 is lower than the joint strength of the end joint parts 103a and 103b, it is possible to Since the possibility of separation of the bonding of the packaging materials 101 of the inner joint portion 102 is reduced, it becomes easy to hold the packaging material 101 of the unsealed individual package 100 until one of the end joint portions 103a and 103b is unsealed. bag. The bag-shaped packaging material 101 can be used to put the used absorbent article 1 in and carry it or throw it away.

In addition, the [bonding strength] of the packaging materials 101 of the inner joint part 102 and the end joint parts 103a and 103b refers to the bonding and separation of the packaging materials 101 of the joint parts 102 and 103 with respect to the individual packaging body 100 . The amount of force per unit area (peeling). That is, the joint strength and the separation strength (peel strength) are the same magnitude of force.

As for the specific method of measuring the bonding strength, first, first and second samples having the same area are cut out from the individual package 100 to be measured. Sample 1 is a portion of the packaging material 101 provided with the inner joint portion 102, and sample 2 is a portion of the packaging material 101 provided with the end joint portions 103a, 103b. Next, the sample 1 or the sample 2 is set on the upper and lower jigs of a tensile testing machine (for example, Instron Co., Ltd. Instron series 5564). Then, the upper and lower clamps are separated at a predetermined pulling speed (for example, 300 mm/min), and the samples 1 and 2 are pulled. Obtain the maximum load (N) until the distance between the clamps is separated. For each of the samples 1 and 2, n (for example, 10) measurement results are obtained, and the average value of the n maximum loads (N) is calculated. Then, the average value (N) of the sample 1 can be taken as the joint strength of the inner joint portion 102, the average value (N) of the sample 2 can be taken as the joint strength of the end joint portions 103a and 103b, and the two value to compare. In addition, the bonding strength demonstrated below can also be compared by the same measurement method.

Moreover, in the packing state, the one side end portion and the other side end portion in the vertical direction of the absorbent article 1 are provided with the one side end portion joining portion 103a and the other side end portion joining portion 103b, respectively, and the one side end portion is provided with the one side end portion joining portion 103a and the other side end portion joining portion 103b. The joint strength of the part joint part 103a is higher than the joint strength of the other side end joint part 103b, and it is preferable that the waist opening 1a of the absorbent article 1 is provided on one side in the vertical direction. The waist opening 1a is a portion that forms an opening toward the inner side of the absorbent article 1 in the up-down direction of the absorbent article 1 in the folded state. Therefore, the cooling agent 26 is more likely to volatilize than the upper and lower folded portions BL of the absorbent article 1. . Therefore, in the case where the bonding strength of the one side end portion joining portion 103a is higher than that of the other side end portion joining portion 103b, compared with the case where the waist opening portion 1a is provided on the other side in the vertical direction, by By orienting the waist opening 1a to the side of the one side end joint 103a with higher joint strength, the cooling agent 26 leaking from the waist opening 1a can be reduced to flow out to the outside of the individual package 100 through the one side end joint 103a. Yu.

<Individual Package 110 in Packaged State of Other Embodiments> The individual packages 110 of other embodiments will be described. FIG. 13A is a plan view of an individual package 110 of another embodiment. The following individual packages 110 have the same reference numerals and the like, and the detailed description thereof will be omitted for the parts that are common to the structures of the individual packages 100 of the aforementioned embodiment. In the aforementioned embodiment, the risk of the cooling agent 26 flowing out from at least one of the leg openings 1b to the outside of the absorbent article 1 is reduced to the outside of the individual package 100 (packaging material 101 ). However, the individual package 110 is a In order to reduce the possibility that the cooling agent 26 which flows out from the waist opening part 1a to the outside of the absorbent article 1 flows out to the outside of the individual package body 110.

As shown in FIG. 13A , in the individual package 110 , the left-right direction of the absorbent article 1 is along the folding direction of the packaging material 101 , and the vertical direction of the absorbent article 1 is perpendicular to the folding direction of the packaging material 101 . In the direction, the front-rear direction of the absorbent article 1 is along the thickness direction of the packaging material 101 . In addition, the packaging method of the packaging material 101 by the individual packaging body 110 is substantially the same as that of the individual packaging body 100 described above, and the inner joint portion 102 of the individual packaging body 110 is along the left-right direction of the absorbent article 1 (the direction of the packaging material 101). bending direction), and the end joint parts 103a and 103b are along the up-down direction of the absorbent article 1 (the direction perpendicular to the packaging material 101). That is, the individual package 110 accommodates the absorbent article 1 in a state in which the absorbent article 1 accommodated in the folded state of the individual package 100 is rotated 90 degrees.

The individual package 110 is provided with one side folded portion LC1 in a folded state in which the absorbent article 1 provided with the cooling agent 26 is folded by the left and right folded portions LB, RB, and the vertical folded portion BL, similarly to the aforementioned embodiment. The packaging material 101 is used for packaging. This packaging material 101 has an oxygen permeability of 200 cc/m ² /day/atm or less, and one side folded portion LC1 is along the left-right direction of the absorbent article 1 . Moreover, one side bending part LC1 opposes the waist opening part 1a of the absorbent article 1. As shown in FIG.

One side of the packaging material 101 having an oxygen permeability of 200 cc/m ² /day/atm or less can be folded by facing the waist opening 1 a along the left-right direction of the absorbent article 1 by one side bending portion LC1 . The portion LC1 covers at least a part of the waist opening 1a, and thus functions as a cover for reducing the flow of the cooling agent 26 from the waist opening 1a to the outside of the individual package 110. By reducing the risk of the cooling agent 26 flowing out of the waist opening 1a flowing out to the outside of the individual package 110, it is possible to reduce the possibility that the amount of the cooling agent 26 staying inside the individual package 110 will decrease, and the wearer can open the package. The effect of the cooling agent 26 is easily felt when the individual package 110 is worn, when the absorbent article 1 is worn, or the like.

<Individual Package 120 in Packaged State of Other Embodiments> The individual package body 120 concerning other embodiment is demonstrated. FIG. 13B is a plan view of the individual package 120 of another embodiment. The following individual packages 120 are given the same reference numerals and the like for the parts that have the same configuration as those of the individual packages 100 of the aforementioned embodiment, and detailed descriptions thereof will be omitted.

In the above-described embodiment, a part of the folded portion of the one side extension portion 10L and a portion of the folded portion of the other side extension portion 10R are overlapped in the thickness direction (front-rear direction), but the invention is not limited to this. As shown in FIG. 13B , it is also possible to fold so that the part of the extension part 10L on one side and the part of the extension part 10R on the other side which are folded at the folding reference positions B1 and B2 do not overlap in the thickness direction. Thereby, the amount of the cooling agent 26 flowing out to the outside through the opening 1b of the leg opening 1b can be reduced by the bent parts LC1 and LC2 of the packaging material 101 with an oxygen permeability rate of 200 cc/m ² /day/atm or less, and also The thickness of the absorbent article 1 in the folded state can be reduced, and the individual package 100 can be made more compact.

＜＜＜Packing bag 200＞＞＞ A plurality of individual packages 100 can also be sold and distributed as the package bag 200 accommodated in the bag body 201 . FIG. 14A is a schematic perspective view of the packaging bag 200 . FIG. 14B is a diagram illustrating the package bag 200 viewed from the side 200C side.

As shown in FIG. 14A , the packaging bag 200 includes: a plurality of individual packaging bodies 100 ; a bag body 201 for accommodating the plurality of individual packaging bodies 100 ; and a handle portion 202 for carrying and transporting the packaging bag 200 . The packaging bag 200 has an up-down direction, a left-right direction, and a front-rear direction that are orthogonal to each other. The packaging bag 200 has a substantially rectangular shape, and the packaging bag 200 includes a front face 200A and a back face 200B facing in the front-rear direction, a pair of side surfaces 200C facing in the left-right direction, and an upper face 200C facing in the vertical direction. Surface 200D and bottom surface 200E.

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

As described above, it is possible to reduce the risk of the cooling agent 26 flowing out of the individual package 100, and by using the gas-barrier bag 201, even when the cooling agent 26 flows out of the individual package 100, the cooling agent can be reduced. 26 may flow out to the outside through the bag body 201, so the wearer can easily feel the effect of the cooling agent 26 when opening the packaging bag 200 and the individual packaging body 100, when wearing the absorbent article 1, and the like.

Furthermore, the oxygen permeability of the packaging material 101 of the individual packaging body 100 is preferably lower than the oxygen permeability of the bag body 201 of the packaging bag 200 . As described above, the oxygen permeability of the packaging material 101 of the individual package 100 is 2.0 cc/m ² /day/atm, and the oxygen permeability of the bag body 201 of the packaging bag 200 is 80 cc/m ² /day/atm. Thereby, compared with the case where the oxygen permeability of the packaging material 101 is higher than that of the bag body 201, it becomes easier to reduce the amount of the cooling agent 26 flowing out from the individual package 100 to the outside. 26 is maintained inside the individual package 100, and the amount of the cooling agent 26 existing on the outside of the individual package 100 and inside the bag 201 can be reduced, and the volatilization of the cooling agent 26 can be reduced, so it becomes easier for the wearer to feel Effect of Cooling Agent 26.

In the individual package 100, the ends in the left-right direction of the absorbent article 1 in the folded state are covered by the bent parts LC1 and LC2 of the packaging material 101, whereas the ends in the vertical direction of the absorbent article 1 in the folded state are covered with The parts are joined by the end joint parts 103a and 103b. Therefore, the cooling agent 26 may flow out from the end joint parts 103a and 103b rather than the bent parts LC1 and LC2. In particular, in the other end joint 103b having a lower joint strength than the one end joint 103a, the cooling agent 26 may flow out through the other end joint 103b.

On the other hand, the individual package 100 is provided with the one side edge part joining part 103a and the other side end part joining part 103b in the edge part on one side of the vertical direction of the absorbent article 1, and the edge part on the other side, respectively. The joint strength of the one side end portion joint portion 103a is higher than the joint strength of the other side end portion joint portion 103b. Such an individual package 100 is accommodated so that the up-down direction of the packaging bag 200 and the up-down direction of the absorbent article 1 are aligned, and the other side end joint portion 103b and the bottom surface of the bag body 201 (the bottom surface 200E of the packaging bag 200 ) are accommodated. ) contact is preferred. That is, in the present embodiment, as shown in FIG. 14B , two individual packages 100 are stacked in the up-down direction and housed, and the up-down direction of the packaging bag 200 is perpendicular to the end joint portions 103a and 103b, and is housed The bonding strength of the individual package 100 on the lower side is weaker than that of the one side end bonding portion 103a, and the other side end portion bonding portion 103b is in contact with the bottom surface 200E.

Since the packaging material 101 is a flexible sheet-like member, the upper and lower parts of the individual packages 100 outside the end joints 103a and 103b are lower in rigidity and softer than the end joints 103a and 103b. Therefore, as shown in FIG. 14B , if the individual package 100 is accommodated so that the up-down direction of the packaging bag 200 and the up-down direction of the absorbent article 1 are aligned, the individual package 100 is accommodated in the lowermost individual package of the packaging bag 200 . In 100, the portion below the end joint portion 103b on the other side is bent in the left-right direction of the packaging bag 200 (the thickness direction of the individual packaging body 100) by the weight of the two individual packaging bodies 100 so that the other side is bent. The end engaging portion 103b becomes easy to come into contact with the bottom surface 200E. Even when the bonding strength of the other side end portion bonding portion 103b of the individual package 100 is weaker than the bonding strength of the one side end portion bonding portion 103a, the other side end portion bonding portion 103b is in contact with the bottom surface 200E. The gap between the other side end joint portion 103b and the bottom surface of the bag body 201 is less likely to be generated, thereby reducing the risk of the cooling agent 26 flowing out from the other side end joint portion 103b to the outside of the individual package 100 .

About the packaging bag 200, although the structure which accommodated the some individual packaging body 100 was demonstrated as an example, it is not limited to this. A structure in which one individual package body 100 is accommodated in the packaging bag 200 may also be used. In addition, the packaging bag 200 may also be a structure for accommodating a plurality of (or one) individual packaging bodies 110 .

==Other implementation forms== The above-described embodiments are intended to facilitate understanding of the present invention, and are not intended to limit the interpretation of the present invention. The present invention can be changed and improved without departing from the scope of the technical idea, and it is a matter of course that the present invention also includes the equivalents thereof.

In the said embodiment, although the packaging material 101 was used as the individual package 100 provided with the one side bending part LC1 and the other side bending part LC2, it is not limited to this. The packaging material 101 may be an individual package 100 having only one folded portion, an individual package 100 having three or more folded portions in the packaging material 101, and the like. In addition, the individual packaging body 100 may also have a structure without the inner joint portion 102, and the inner joint portion 102 may not be provided in the central portion of the orthogonal direction. For example, the inner joint portion 102 may be provided on the other side of the orthogonal direction. side end.

Moreover, in the said embodiment, although the absorbent article 1 of a folded state was made into the folded state which is folded by the left and right folded parts LB, RB and the upper and lower folded parts BL, it is not limited to this. The absorbent article 1 in the folded state may be, for example, folded by the left and right folded parts LB, RB, and not folded by the vertical and The folded state of RB. In addition, a structure in which only one of the left and right folded portions LB and the left and right folded portions RB is folded may be employed.

In the above-described embodiment, in the individual package 100 in the packaged state, the length N from the vertically folded portion BL to the waist opening portion 1a in the vertical direction is the length from the vertically folded portion BL to the end of the crotch portion 10m. The absorbent article 1 of the folded state in the state of length M or more (N≧M) is not limited to this. In the individual package 100 in the packaged state, the length from the top-bottom folded portion BL to the end of the crotch portion 10m in the vertical direction may be longer than the length from the top-bottom folded portion BL to the waist opening 1a (M> N). In this case, in the thickness direction of the individual package 100 (the front-rear direction of the absorbent article 1 ), the inner joint portion 102 is preferably provided at a position closer to the crotch portion 10m than the waist opening 1a. Thereby, since the crotch portion 10m can cover the waist opening 1a, and the waist opening 1a is sandwiched between the crotch portion 10m and the packaging material 101, the risk of the cooling agent 26 flowing out from the waist opening 1a can be reduced.

In the aforementioned embodiment, the cooling agent 26 is a cooling agent that stimulates the thermosensitive TRP channel, but it is not limited to this. As the cooling agent 26, those which reduce the ambient temperature by the heat of vaporization, for example, alcohols such as methanol and ethanol can be used.

Moreover, in the said embodiment, although the cooling feeling agent 26 was used as an example of a volatile substance, it is not limited to the cooling feeling agent 26, For example, volatile substances, such as a warming agent and a fragrance, may be used. Fragrance can be used to replace the cooling agent 26, and can also be used together with the cooling agent 26, the warming agent, and the like.

Furthermore, as a spice, especially in the case of using a green herbal style spice (like the aroma of green herbal), it does not cause physical irritation to the body, does not require oral administration, and can safely and simply soothe the mind. discomfort symptoms. In addition, comfort can also be obtained.
