[0065] According to such a pant-type absorbent article, an inappropriate position in the thickness direction of the volatile substance can be avoided, and the volatile substance can also be close to the wearer's skin, and thus the effect of the volatile substance can be improved.

[0066] ==First Embodiment======

[0067] As an example of the absorbent article provided with a volatile substance of the first embodiment, a pant-type absorbent article 1 provided with a thermosensitive agent 26 (corresponding to a volatile substance) described later is described. In the following description, a sanitary absorbent article 1 is described, but the absorbent article 1 of the present embodiment also includes, for example, diapers for adults and infants, and the like, and the use is not limited to sanitary use.

[0068] Fig. 1 is a schematic perspective view of the pants-type absorbent article 1, Fig. 2 is a plan view of the pants-type absorbent article 1 in an unfolded state.

[0069] In Fig. 1 the pants-type state shown in FIG. 1, the absorbent article 1 has a "vertical direction", a "lateral direction", and a "front-rear direction" that intersect each other. Also, the vertical direction is set as the longitudinal direction of the paper, the upper side (lower side) of the paper is set as the "upper" ("lower") of the vertical direction, and in the lateral direction, the left side (right side) of the paper is set as the left (right) of the lateral direction. In addition, in the front-rear direction, the side that becomes the abdominal side of the wearer when worn is set as the "front side", and the side that becomes the back side of the wearer is set as the "rear side". Fig. 1 In

[0070] the unfolded state of the absorbent article 1 shown in FIG. 2 (the state in which the pants-type absorbent article 1 is spread on a plane before being formed into a pants-type), the absorbent article 1 has a "length direction", a "width direction", and a "thickness direction" that intersect each other. Also, the longitudinal direction of the paper is set as the length direction, the upper side (lower side) of the paper is set as the "front (abdominal side)" ("rear (back side)") of the length direction, the direction orthogonal to the length direction on the paper is set as the width direction, and the left side (right side) of the paper is set as the left (right) of the width direction. In addition, the direction orthogonal to the length direction and the width direction (the direction that penetrates the paper) is set as the thickness direction, and in the thickness direction, the side that comes into contact with the skin of the wearer is set as the "skin side", and the opposite side is set as the "non-skin side". Fig. 2 Fig. 2 In addition, the plan view (for example, ) of the present embodiment indicates the elongated state of the object. Here, the "elongated state" means that the members shown in the plan view are elongated to a state in which there are no wrinkles by elongating each elastic body (for example, the crotch elastic 30, the stretchable sheet, and the like described later) possessed by the absorbent article 1. For example, in

[0071] , it means a state in which the dimensions of the waist member 10 and the absorbent main body 20 described later that constitute the absorbent article 1 become the same as or close to the dimensions of the members alone. Fig. 2 Fig. 2 The absorbent article 1 of the present embodiment includes a waist member 10 and an absorbent main body 20, and in the following, first, the process of generating the waist member 10 and the absorbent article 1 into a pants-type will be described. Then, the absorbent main body 20 will be described later. In addition, in the present embodiment, a thermosensitive agent 26 is provided in the absorbent main body 20.

[0072] As

[0073] As​Fig. 2 As shown, the waist member 10 has a substantially hourglass shape in plan view in the unfolded state. That is, the central portion in the longitudinal direction is recessed toward the inner side in the width direction, and the recessed portion forms the waist opening portion la when shaped into the panty type. Fig. 1 As shown, the pair of leg opening portions lb. In addition, the waist member 10 has an unillustrated stretchable sheet that stretches and contracts in the width direction. Thus, the waist member 10 of the panty type absorbent article 1 stretches and contracts in the left-right direction.

[0074] In addition, the waist member 10 has a front side waist member 10f on the front side of a center fold line CL that is located in the center of the absorbent article 1 in the longitudinal direction, and a back side waist member 10b on the back side of the center fold line CL. Furthermore, the front side waist member 10f (the back side waist member 10b) has a waist front end portion 10ff (a waist back end portion 10bf) at the end portion on the front side (the back side) that extends in the width direction, and a front side joint portion 10fe (a back side joint portion 10be) that is provided at both end portions in the left-right direction and extends in the longitudinal direction (all are Fig. 2 in the oblique line view).

[0075] In the process of producing the absorbent article 1 into the panty type, first, the absorbent main body 20 is arranged at a predetermined position of the waist member 10 in the unfolded state, and the absorbent article 1 in the unfolded state is produced. That is, the face on the non-skin side of the absorbent main body 20 is taken as a joint face, and the joint face is placed and joined to the predetermined position of the waist member 10 in the unfolded state. That is, the waist member 10 is arranged in the thickness direction on the non-skin side of the absorbent main body 20.

[0076] Then, the absorbent main body 20 and the waist member 10 in the unfolded state are folded in the longitudinal direction. That is, the center fold line CL shown in Fig. 2 is taken as a crease, and the absorbent main body 20 and the waist member 10 are folded in the longitudinal direction in such a manner that the skin side of the front side waist member 10f and the skin side of the back side waist member 10b face each other.

[0077] In this case, the front side joint portion 10fe and the back side joint portion 10be of the waist member 10 are close, and thus the left-right front side joint portions 10fe and the left-right back side joint portions 10be are joined, respectively.

[0078] That is, the left-right both end portions of the waist member 10 are joined in the longitudinal direction, and thus the waist front end portion 10ff and the waist back end portion 10bf form the waist opening portion la on the upper side of the waist member 10.

[0079] In addition, the waist member 10 has a position on the outer side on the left side in the width direction from the absorbent main body 20 (in the Fig. 2the left side of the position shown by the dotted line on the left side (in the case of the short pants-type absorbent article 1 shown in Fig. 1, the position shown by the dotted line on the left side in the lower part of the drawing) of the absorbent main body 20, and the right side of the position shown by the dotted line on the right side (in the case of the short pants-type absorbent article 1 shown in Fig. 1, the position shown by the dotted line on the right side in the lower part of the drawing) of the absorbent main body 20. Fig. 2 the right side of the position shown by the dotted line on the right side (in the case of the short pants-type absorbent article 1 shown in Fig. 1, the position shown by the dotted line on the right side in the lower part of the drawing) of the absorbent main body 20.

[0080] The short pants-type absorbent article 1 is a structure in which the waist member 10 abuts against the front side (abdomen) and the back side (back) of the wearer's body (abuts against the waist of the wearer), and does not fall down during wearing due to the effect of the stretchability of mainly the waist member 10 in the left-right direction (fastening to the body). Thus, the absorbent main body 20 joined to the waist member 10 is supported in the upward-downward direction by the waist member 10 in a state in which it abuts against the crotch portion of the wearer, which is the portion of the absorbent main body 20 that abuts against the skin of the wearer during wearing, from the lower abdominal portion via the crotch portion to the sacrum portion of the buttocks.

[0081] That is, the absorbent article 1 has an abdomen, a back, and a crotch, and is a short pants-type formed with a waist opening portion la and a pair of leg opening portions lb, and is supported by the stretchable sheet or the like possessed by the waist member 10 so as not to fall down during wearing.

[0082] In addition, "abut" means to come into contact with and touch, and if at least a portion of a member abuts against a wearer, the member becomes in a state of abutting against the wearer. For example, a state in which a portion that stretches in the waist member 10 contacts the wearer, and a portion that does not stretch does not contact the wearer, is a state in which the waist member 10 abuts against the wearer.

[0083] In addition, as a joining method of joining the aforementioned absorbent main body 20 and the waist member 10 or the like, for example, a publicly known joining method such as an adhesive, heat sealing, ultrasonic sealing, a combination thereof, or the like can be exemplified.

[0084] <<<About the Absorbent Main Body 20>>>

[0085] Next, the absorbent main body 20 will be described. Figs. 3 to 5 The absorbent main body 20 will be described. Fig. 3 is a cross-sectional view of the absorbent main body 20 taken along the line A-A of Fig. 4 is a cross-sectional view of the absorbent main body 20 taken along the line A-A of Fig. 3 is a cross-sectional view of the absorbent main body 20 taken along the line A-A of Fig. 5 will be described later.

[0086] The absorbent main body 20 of the present embodiment is a sanitary napkin that is a sanitary absorbent main body 20 for use in menstruation. That is, the absorbent main body 20 has a liquid-absorbing absorbent core 22, and the absorbent core 22 is covered with a core cover sheet 22a on the outer peripheral surface.

[0087] The absorbent core 22 is obtained by molding a liquid absorbent raw material into a predetermined shape. In this embodiment, it is molded into a roughly rectangular shape when viewed from above. Fig. 3 (The oblique line drawing), and the convex shape when viewed in section ( Fig. 4 (The shaded area). As a liquid-absorbent raw material, examples include highly absorbent polymers (so-called SAP) contained in liquid-absorbent fibers such as pulp fibers. As the core-coating sheet 22a, examples include liquid-permeable sheets such as cotton paper and non-woven fabrics. Alternatively, the core-coating sheet 22a may be omitted.

[0088] The absorbent body 20, excluding the absorbent core 22, such as Fig. 4 As shown, a first skin side sheet 24a, a second skin side sheet 24b, and a temperature-sensitive agent 26 are provided at a position closer to the skin than the absorbent core 22, and a crotch elastic band 30 (equivalent to an elastic member) and a non-skin side sheet 24c are provided at a position closer to the non-skin than the absorbent core 22 along the length direction.

[0089] Furthermore, the absorbent body 20 includes side panels 24d, which are configured such that at both ends of the absorbent body 20 in the width direction, the side panels extend from the position closest to the non-skin side in the thickness direction to a position closer to the skin side than the first skin side panel 24a, and then fold back to the non-skin side. Moreover, the portion of the side panels 24d extending to the skin side forms a three-dimensional pleat 50 (equivalent to a leak-proof wall) as described later. In other words, a pair of three-dimensional pleats 50 formed by the side panels 24d are provided at both ends of the absorbent body 20 in the width direction along the vertical direction.

[0090] In addition, multiple bends 40 (equivalent to compression grooves) are formed on the skin side of the absorbent body 20 (absorbent core 22).

[0091] In addition, to prevent the temperature-sensitive agent 26 from leaking outward, the three-dimensional pleats 50 are preferably made of the same number of nonwoven fabrics from the fulcrum 50B to the vertex 50S, specifically more than two sheets.

[0092] The first skin-permeable side panel 24a is a liquid-permeable sheet component that can come into contact with the wearer's skin when worn, such as being formed of hydrophilic hot-air nonwoven fabric, spunbond nonwoven fabric, etc. The second skin-permeable side panel 24b is a sheet component having substantially the same function and structure as the first skin-permeable side panel 24a, and is layered on the non-skin-permeable side of the first skin-permeable side panel 24a.

[0093] That is, the absorbent body 20, as a skin side sheet, has a first skin side sheet 24a located at the position closest to the skin and a second skin side sheet 24b located between the first skin side sheet 24a and the absorbent core 22. Alternatively, the second skin side sheet 24b may not be necessary in the absorbent body 20.

[0094] The non-skin side sheet 24c is a liquid-impermeable sheet, and examples include polyethylene films, polypropylene films, and the like. The first skin side sheet 24a and the non-skin side sheet 24c are each sized to cover the entire absorbent core 22.

[0095] The side sheet 24d is partially in contact with the wearer's skin when worn, and is thus formed of, for example, a heat-bonded nonwoven fabric, a spun-bonded nonwoven fabric, or the like.

[0096] The warming agent 26 is provided to alleviate physiological pain and chills in the wearer, and includes a warming stimulant that makes the wearer who has been stimulated feel warm by applying stimulation to the wearer's temperature sensation, and is provided in a state of being mixed with a solvent that is a volatile substance.

[0097] Furthermore, the warming agent 26 is applied in the thickness direction between the first skin side sheet 24a and the second skin side sheet 24b (at least one of the non-skin side of the first skin side sheet 24a and the skin side of the second skin side sheet 24b. In the present embodiment, the non-skin side of the first skin side sheet 24a) Fig. 4 (blackened portion), and is not applied at a place that is in contact with the wearer's skin. The warming agent 26 of the present embodiment vaporizes to reach the wearer's skin, and exerts its main warming effect. The vaporization of the warming agent 26 will be described in detail later.

[0098] Furthermore, the warming agent 26 can also be provided to the absorbent core 22. That is, the warming agent 26 can be provided to at least one of the absorbent core 22 and the skin side sheets (the first skin side sheet 24a and the second skin side sheet 24b).

[0099] The warming stimulant is preferably a compound derived from a plant from the viewpoint of the wearer's sense of security. As the warming stimulant, for example, capsicoside, capsaicin (LD50: 47 mg / kg, molecular weight: 305), capsaicinoids (dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, synthetic capsaicin, and the like), capsanthin, benzyl nicotinate (LD50: 2188 mg / kg, molecular weight: 213), beta-butoxyethyl nicotinate, N-acyl vanillylamides, nonivamide, chili powder, chili tincture, chili extract, vanillyl nonanoate, vanillyl alcohol alkyl ether derivatives (e.g., vanillyl ethyl ether, vanillyl butyl ether (LD50: 4900 mg / kg, molecular weight: 210), vanillyl pentyl ether, vanillyl hexyl ether), isovanillyl alcohol alkyl ether, ethyl vanillyl alcohol alkyl ether, veratroyl alcohol derivatives, substituted benzyl alcohol derivatives, substituted benzyl alcohol alkyl ethers, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, ginger extract, ginger oil, gingerol (LD50: 250 mg / kg, molecular weight: 294), zingerone, hesperidin, pyrrolidone carboxylic acid, and any combination thereof can be listed.

[0100] The solvent is not particularly limited as long as it can contain the temperature- sensing stimulant, and for example, an oleophilic solvent and a hydrophilic solvent can be given. The solvent can dissolve, disperse, or the like, the temperature-sensing stimulant.

[0101] As the oleophilic solvent, an oil and fat such as a natural oil (e.g., a fatty acid ester such as a triglyceride, coconut oil, linseed oil, tri (octanoic acid / decanoic acid) glyceride, or the like), a hydrocarbon (e.g., a paraffin such as liquid paraffin), or the like can be given.

[0102] The hydrophilic solvent can include water and an alcohol. As the alcohol, a lower alcohol such as methanol, ethanol, ethylene glycol, glycerol, or the like, a higher alcohol such as octanol, lauryl alcohol, myristyl alcohol, or the like, or the like can be given.

[0103] In addition, the temperature-sensing agent 26 preferably stimulates the temperature- sensitive TRP channel. For example, TRPV1, which is one of the temperature-sensitive TRP channels, is activated by stimulation of capsaicin, acid, or the like. Furthermore, if the wearer's TRPV1 is activated, heat production is caused via the sympathetic nervous system (the wearer generates heat in the body).

[0104] That is, rather than warming the wearer by making itself high-temperature like a disposable hand warmer for carrying, it is preferable to warm the wearer without making itself high-temperature like capsaicin or the like. In this case, the wearer can feel cool and warm without being burned or scalded by low temperature.

[0105] In addition, if the temperature-sensing agent 26 does not directly contact the wearer's skin, it is difficult to produce an effect. That is, for example, a volatile substance such as a perfume can exert an effect of suppressing odor around if it is a gas, but the temperature-sensing agent 26 directly contacts the wearer's skin after vaporization and exerts its main effect. Therefore, by making the temperature-sensing agent 26 contact the wearer's skin through a nonwoven fabric or the like, the wearer can gradually feel the effect of the temperature-sensing agent 26 at the skin.

[0106] Fig. 5 is a view indicating the coated region 26p and the non-coated region 26n of the temperature-sensing agent 26. As shown in Fig. 5 , the temperature-sensing agent 26 is coated in a pair of coated regions 26p (hatched portions of Fig. 5 ) having a predetermined size in the width direction and along the up-down direction (length direction). Thus, a non-coated region 26n in which the temperature-sensing agent 26 is not coated along the length direction is provided at the central portion in the width direction of the absorbent body 20.

[0107] In the present embodiment, a non-coated region 26n having a width dimension of 15 mm is provided at the central portion in the width direction of the absorbent body 20, and a pair of coated regions 26p having a width dimension of 25 mm are provided at both outer sides in the width direction of the non-coated region 26n. In addition, the coated regions 26p and the non-coated region 26n are continuous regions from the front end to the rear end in the length direction of the absorbent body 20.

[0108] Next, the vaporization of the thermo-sensitive agent 26 will be described. The solvent of the thermo-sensitive agent 26 vaporizes in a state in which the thermo-sensitive stimulant is contained. That is, the solvent containing the thermo-sensitive stimulant vaporizes to reach the wearer's skin, and the thermo-sensitive stimulant that has reached causes stimulation to the wearer's temperature sensation. That is, in the present embodiment, even if the thermo-sensitive agent 26 does not directly abut against the wearer's skin, the thermo-sensitive agent 26 vaporizes, and the vaporized thermo-sensitive agent 26 abuts against the wearer's skin.

[0109] Furthermore, the amount of vaporization of such a solvent increases or decreases according to the temperature change of the thermo-sensitive agent 26 caused by the transfer of the wearer's body temperature or the like, the magnitude of the stretching action of the absorbent body 20 in which the thermo-sensitive agent 26 is located (if the stretching is greater, the thermo-sensitive agent 26 also moves to a greater extent, and the amount of vaporization increases). That is, by adjusting the situation in which the body temperature is transferred to the thermo-sensitive agent 26 (the distance of the thermo-sensitive agent 26 from the wearer's skin or the like), the stretching situation of the absorbent body 20 in which the thermo-sensitive agent 26 is located (the presence or absence of an elastic member or the like), or the like, it is possible to adjust the amount of vaporization. That is, it is possible to adjust the strength of the thermo-sensitive stimulation felt by the wearer, the length of the duration in which the effect of the thermo-sensitive agent is exerted (the time during which the solvent vaporizes).

[0110] As shown in Figs. 1 and 2, the crotch elastic member 30 is provided from the front side at which the lower abdomen portion abuts to the rear side at which the buttocks portion abuts via the crotch portion at the central portion in the left-right direction (width direction) of the absorbent body 20. That is, the crotch elastic member 30 is provided along the up-down direction (length direction) of the absorbent body 20. Fig. 3 Fig. 4 As shown in Figs. 1 and 2, the crotch elastic member 30 is provided from the front side at which the lower abdomen portion abuts to the rear side at which the buttocks portion abuts via the crotch portion at the central portion in the left-right direction (width direction) of the absorbent body 20. That is, the crotch elastic member 30 is provided along the up-down direction (length direction) of the absorbent body 20.

[0111] In addition, the crotch elastic member 30 is cut after being joined in a continuous elongated state to the non-skin side sheet 24c, and thus the crotch elastic member 30 of the portion that is not joined is contracted toward the joined portion after being cut, and the crotch elastic member 30 in a state in which it is not elongated is provided to the absorbent body 20. That is, at the front side end of the crotch elastic member 30, the crotch elastic member 30 in a state in which it is not elongated is provided.

[0112] ​This portion is more rigid than the portion without the crotch elastic band 30. Therefore, when wearing the absorbent garment 1, after the absorbent body 20 deforms into a cup shape (or a U-shape when viewed from the left and right in the shorts type), it is difficult for this shape of the absorbent body 20 to break. That is, in the shorts-type absorbent garment 1, for example, when a force is applied from the upper side in the vertical direction to deform the absorbent body 20, if the portion with the crotch elastic band 30 in its unstretched state is more rigid than the portion without the crotch elastic band 30, it is less likely to deform, thus making it less likely for the shape of the absorbent body 20 to break.

[0113] In addition, the crotch elastic band 30 of this embodiment is provided on the non-skin side of the non-skin side piece 24c which is closer to the non-skin side than the absorbent core 22, but it is not limited to this. For example, it can be provided on the skin side of the non-skin side piece 24c, or it can be provided not only on the non-skin side but also on the skin side of the absorbent core 22.

[0114] In addition, as a component for stretching the absorbent body 20, it is not limited to the crotch elastic band 30, but may also be a stretchable nonwoven fabric or a stretchable membrane.

[0115] The transition section 40 is designed so that when the wearer wears the absorbent material 1, the absorbent body 20 deforms along the wearer's body (becoming a deformed crease), such as... Fig. 4 As shown, the absorbent body 20 (absorbent core 22) is formed in a concave shape on the skin side, extending from the skin side to the non-skin side.

[0116] In this embodiment, the concave shape of the transition portion 40 is formed by compressing the absorbent body 20 (absorbent core 22) coated with the temperature-sensitive agent 26 from the skin side. That is, the transition portion 40 is a compression groove in which the density of the absorbent core 22 is higher than that of the surrounding area.

[0117] In this embodiment, such as Fig. 3 As shown, a front bend 41 with a predetermined length in the width direction is provided at the front end of the absorbent core 22 in the length direction and in the portion that mainly abuts the lower abdomen when worn. The front bend 41 is mainly provided so that the absorbent body 20 runs along the lower abdomen.

[0118] In addition, a plurality of pairs of bends 42 are provided at predetermined intervals along the width direction, spaced apart from each other on the rear side of the front bend 41 in the length direction. These pairs of bends 42 are mainly provided along the crotch and buttocks with the absorbent body 20.

[0119] In addition, the depth of the recess of the transition portion 40 in this embodiment is not constant, with some parts being shallower and others deeper. By adjusting the depth of the recess of the transition portion 40, the deformation of the absorbent body 20 can be adjusted.

[0120] The three-dimensional gathers 50 are provided to suppress leakage of liquid from the inner side in abutment with the thighs of the wearer. That is, the pair of three-dimensional gathers 50 are provided at both end portions in the width direction of the absorbent main body 20.

[0121] In addition, as shown in Fig. 3 and Fig. 4 , the pair of three-dimensional gathers 50 have an adhesive region 54 (corresponding to a joint region) in which an adhesive is applied to the respective front upper end portion and the rear upper end portion, and are joined to the first skin side sheet 24a at the adhesive region 54. That is, the pair of three-dimensional gathers 50 have the adhesive region 54 for fixing the pair of three-dimensional gathers 50 at the respective front upper end portion and the rear upper end portion.

[0122] <<Packaging of the Absorbent Article 1>>

[0123] The absorbent article 1 of the present embodiment is folded after being formed into the short pants type, and one absorbent article 1 is packaged in one packaging container. That is, the absorbent article 1 is individually packaged, and in the packaged state, is in a folded state.

[0124] In the following, the Figs. 6 to 9 absorbent article 1 in the packaged state will be described. Fig. 6 is a plan view schematically showing the longitudinal fold line BL, the left side fold line LB, and the right side fold line RB in the front view of the short pants type absorbent article 1. Fig. 7 The upper drawing of is a plan view schematically showing the short pants type absorbent article 1 in which the left side extension portion 10L and the right side extension portion 10R are folded inwardly, and the lower drawing is a cross-sectional view taken along the line B-B. Fig. 8 The left drawing of is a plan view schematically showing the short pants type absorbent article 1 folded in the up-down direction with the longitudinal fold line BL as a crease, and the right drawing is a side view schematically showing the absorbent main body 20 as viewed from the right side. Fig. 9 is a plan view of the absorbent main body 20 showing the position of the longitudinal fold line BL of the absorbent main body 20.

[0125] As shown in Fig. 7 , for the absorbent article 1 of the present embodiment, after the left side extension portion 10L is folded inwardly (rightward) at the left side fold line LB and the right side extension portion 10R is folded inwardly (leftward) at the right side fold line RB, the short pants type absorbent article 1 is packaged in the packaging container in a folded state in the up-down direction with the longitudinal fold line BL as a crease.

[0126] That is, the absorbent article 1 has the left side fold line LB as a crease when at least a portion of the left side extension portion 10L is folded rightward, and the right side fold line RB as a crease when at least a portion of the right side extension portion 10R is folded leftward.

[0127] In addition, in the present embodiment, as shown in Fig. 7 both the left-side extension portion 10L and the right-side extension portion 10R are folded back. In addition, either the left-side extension portion 10L or the right-side extension portion 10R can be folded back first.

[0128] In addition, in the state shown in Fig. 7 in the state before the absorbent article 1 is folded in the up-down direction, at least a portion of the thermosensitive agent 26 overlaps at least one of the left-side extension portion 10L folded with the left-side fold line LB as a crease and the right-side extension portion 10R folded with the right-side fold line RB as a crease, when viewed in the front-rear direction.

[0129] In addition, in the pair of leg-opening portions lb, the left-side extension portion 10L and the right-side extension portion 10R overlap in the up-down direction Fig. 8 of the range of lbY shown in the drawing. That is, the absorbent article 1 has a pair of leg-opening portions lb on both sides in the left-right direction, and at least a portion of the pair of leg-opening portions lb overlaps at least one of the left-side extension portion 10L and the right-side extension portion 10R in the up-down direction in the packed state.

[0130] Furthermore, in the state where both the left-side extension portion 10L and the right-side extension portion 10R are folded inwards in the left-right direction, as shown in Fig. 6 the absorbent article 1 is folded in the up-down direction with the longitudinal fold line BL as a crease. That is, at least one of the left-side extension portion 10L folded with the left-side fold line LB as a crease and the right-side extension portion 10R folded with the right-side fold line RB as a crease is folded in the up-down direction with the longitudinal fold line BL as a crease.

[0131] The absorbent article 1 is packed in this state, and therefore, the left-side extension portion 10L and the right-side extension portion 10R folded in the up-down direction overlap the thermosensitive agent 26 when viewed in the front-rear direction. That is, for the absorbent article 1, at least a portion of the thermosensitive agent 26 overlaps at least one of the left-side extension portion 10L and the right-side extension portion 10R folded in the up-down direction when viewed in the front-rear direction in the packed state.

[0132] <Regarding the position of the longitudinal fold line BL>

[0133] Next, the positional relationship between the position of the longitudinal fold line BL in the up-down direction and the respective members and the like provided in the absorbent article 1 will be described. Specifically, the positional relationship between the absorbent main body 20, the temperature sensing agent 26 (the application region 26p), the crotch elastic member 30, the turning portion 40, and the respective adhesive regions 54 of the pair of three-dimensional gathers 50 and the longitudinal fold line BL will be described.

[0142] <<<Regarding the Effectiveness of the Present Embodiment>>>

[0143] In the absorbent article 1 provided with the temperature-sensitive agent 26, the temperature-sensitive agent 26 is vaporized and discharged during wear, and it can be difficult to sufficiently exert the effect of the temperature-sensitive agent 26.

[0144] In contrast, the pant-type absorbent article 1 of the present embodiment has an absorbent main body 20 including a liquid-absorbing absorbent core 22 and a skin-side sheet (a first skin-side sheet 24a and a second skin-side sheet 24b) provided at a position on the skin side from the absorbent core 22, and a waist member 10 that is arranged so as to overlap the non-skin side of the absorbent main body 20 and is stretchable in the left-right direction, wherein the temperature-sensitive agent 26 is provided in at least one of the absorbent core 22 and the skin-side sheet (the first skin-side sheet 24a and the second skin-side sheet 24b) (in the present embodiment, the first skin-side sheet 24a), and the pant-type absorbent article 1 is packed in a state of being folded in the up-down direction with a longitudinal fold line BL along the left-right direction as a crease, and has at least a portion of the temperature-sensitive agent 26 at a position on the lower side from the longitudinal fold line BL in a state before the pant-type absorbent article 1 is folded in the up-down direction. Thus, discharge of the vaporized temperature-sensitive agent 26 can be suppressed.

[0145] If the absorbent article 1 is folded in the up-down direction at the longitudinal fold line BL, the crease of the longitudinal fold line BL functions in a manner that divides a space on the lower side of the longitudinal fold line BL and that is the inner side (skin side) of the absorbent article 1 (the hatched portion of the cross-sectional view of FIG. 10) and a space on the upper side of the longitudinal fold line BL and that is the inner side (skin side) of the absorbent article 1 in a state before the absorbent article 1 is folded in the up-down direction. In this way, the space on the lower side of the longitudinal fold line BL, which is divided by the longitudinal fold line BL, is separated from the space on the outer side of the absorbent article 1 that communicates via the waist opening 1a. That is, if the absorbent article 1 is folded in the up-down direction at the longitudinal fold line BL, the crease of the longitudinal fold line BL functions as a cover for the waist opening 1a in the packed state, and thus discharge of the vaporized temperature-sensitive agent 26 can be suppressed. Fig. 7 In contrast, the pant-type absorbent article 1 of the present embodiment has an absorbent main body 20 including a liquid-absorbing absorbent core 22 and a skin-side sheet (a first skin-side sheet 24a and a second skin-side sheet 24b) provided at a position on the skin side from the absorbent core 22, and a waist member 10 that is arranged so as to overlap the non-skin side of the absorbent main body 20 and is stretchable in the left-right direction, wherein the temperature-sensitive agent 26 is provided in at least one of the absorbent core 22 and the skin-side sheet (the first skin-side sheet 24a and the second skin-side sheet 24b) (in the present embodiment, the first skin-side sheet 24a), and the pant-type absorbent article 1 is packed in a state of being folded in the up-down direction with a longitudinal fold line BL along the left-right direction as a crease, and has at least a portion of the temperature-sensitive agent 26 at a position on the lower side from the longitudinal fold line BL in a state before the pant-type absorbent article 1 is folded in the up-down direction. Thus, discharge of the vaporized temperature-sensitive agent 26 can be suppressed.

[0145] If the absorbent article 1 is folded in the up-down direction at the longitudinal fold line BL, the crease of the longitudinal fold line BL functions in a manner that divides a space on the lower side of the longitudinal fold line BL and that is the inner side (skin side) of the absorbent article 1 (the hatched portion of the cross-sectional view of FIG. 10) and a space on the upper side of the longitudinal fold line BL and that is the inner side (skin side) of the absorbent article 1 in a state before the absorbent article 1 is folded in the up-down direction. In this way, the space on the lower side of the longitudinal fold line BL, which is divided by the longitudinal fold line BL, is separated from the space on the outer side of the absorbent article 1 that communicates via the waist opening 1a. That is, if the absorbent article 1 is folded in the up-down direction at the longitudinal fold line BL, the crease of the longitudinal fold line BL functions as a cover for the waist opening 1a in the packed state, and thus discharge of the vaporized temperature-sensitive agent 26 can be suppressed. Fig. 7

[0146] In addition, in the present embodiment, the predetermined region of the absorbent main body 20 along the up-down direction has the coated region 26p coated with the thermosensitive agent 26, and the coated region 26p of the absorbent main body 20 on the upper side than the longitudinal fold line BL is smaller than the coated region 26p of the absorbent main body 20 on the lower side than the longitudinal fold line BL in the state before the short pants-type absorbent article 1 is folded along the up-down direction.

[0147] That is, the crease of the longitudinal fold line BL can function as a cover of the waist opening portion la in the packed state with respect to the region exceeding half of the coated region 26p. That is, the discharge of the vaporized thermosensitive agent 26 is further suppressed.

[0148] In addition, in the present embodiment, the longitudinal fold line BL is located at a position on the lower side than the upper end of the absorbent main body 20 (the upper end of the rear upper end portion 20Be) in the state before the short pants-type absorbent article 1 is folded along the up-down direction, and at least a part of the absorbent main body 20 is folded along the up-down direction with the longitudinal fold line BL as a crease in the packed state.

[0149] According to this state, the absorbent main body 20 is folded along the up-down direction in a state where the rigidity is improved compared to the case where only the waist member 10 is folded along the up-down direction, and thus the habitual bend along the longitudinal fold line BL can be formed in the absorbent main body 20, and the absorbent main body 20 is firmly folded along the up-down direction. That is, the crease of the longitudinal fold line BL can function as a firm cover of the waist opening portion la in the packed state, and the discharge of the vaporized volatile substance can be further suppressed.

[0150] In addition, in the present embodiment, at least a part of the thermosensitive agent 26 is disposed to overlap the longitudinal fold line BL in the state where at least a part of the absorbent main body 20 is folded along the up-down direction with the longitudinal fold line BL as a crease.

[0151] If the absorbent main body 20 is packed (kept for a long time) in the state where it is folded with the longitudinal fold line BL as a crease, the habitual bend along the longitudinal fold line BL is formed in the absorbent main body 20. Also, if the thermosensitive agent 26 is coated in this habitual bend, the wearer can be given a thermosensitive effect caused by the shape of the habitual bend. That is, if the habitual bend is a shape protruding from the non-skin side to the skin side, the thermosensitive agent 26 is close to the skin of the wearer, and thus the temperature of the thermosensitive agent 26 rises and its vaporization is promoted under the action of the body temperature of the wearer, and the effect of the thermosensitive agent 26 can be improved. Also, if the habitual bend is a shape protruding from the skin side to the non-skin side, the thermosensitive agent 26 is away from the skin of the wearer, and thus the irritation of the wearer by the thermosensitive agent 26 is suppressed, and the vaporization of the thermosensitive agent 26 is suppressed, and thus the thermosensitive effect can be made to last for a long time.

[0152] In addition, in the present embodiment, the non-skin surface of the rear upper end portion 20Be of the absorbent main body 20 in the state before the short pants-type absorbent article 1 is folded in the up-and-down direction is opposed to the non-skin surface of the absorbent main body 20 on the rear side of the longitudinal fold line BL and on the front side thereof, and the absorbent main body 20 is folded in the up-and-down direction.

[0153] That is, the habit bend that projects from the non-skin side to the skin side is formed in the sacrum portion of the wearer, and the thermo-receptive agent 26 is located in the habit bend close to the sacrum portion of the wearer, so the temperature of the thermo-receptive agent 26 rises and its vaporization is promoted by the body temperature of the wearer, and the effect of the thermo-receptive agent 26 can be enhanced in the sacrum portion.

[0154] In addition, in the present embodiment, the non-skin surface of the rear upper end portion 20Be of the absorbent main body 20 in the state before the short pants-type absorbent article 1 is folded in the up-and-down direction is opposed to the non-skin surface of the absorbent main body 20 on the rear side of the longitudinal fold line BL and on the front side thereof, and the absorbent main body 20 is folded in the up-and-down direction.

[0155] That is, the non-skin surface of the rear upper end portion 20Be of the absorbent main body 20 in the state before the short pants-type absorbent article 1 is folded in the up-and-down direction is opposed to the non-skin surface of the absorbent main body 20 on the rear side of the longitudinal fold line BL and on the front side thereof, and the absorbent main body 20 is folded in the up-and-down direction.

[0156] In addition, the habit bend that projects from the skin side to the non-skin side is formed in the absorbent main body 20 on the front side (the abdominal side). This habit bend moves the thermo-receptive agent 26 away from the skin of the wearer, so the irritation of the thermo-receptive agent 26 to the wearer is suppressed, and the vaporization of the thermo-receptive agent 26 is suppressed, so the thermo-receptive effect can be sustained for a long period of time. In addition, the habit bend easily follows the bulge of the lower abdomen, so the feeling of oppression during wearing can be suppressed.

[0157] In addition, in the present embodiment, the waist member 10 has a left-side extension portion 10L positioned at a position further to the left than the left-side end of the absorbent main body 20 and a right-side extension portion 10R positioned at a position further to the right than the right-side end of the absorbent main body 20, the pant-type absorbent article 1 has a left-side fold line LB as a crease when at least a portion of the left-side extension portion 10L is folded to the right side and a right-side fold line RB as a crease when at least a portion of the right-side extension portion 10R is folded to the right side, and in a state before the pant-type absorbent article 1 is folded in the up-down direction, at least a portion of the warming agent 26 overlaps at least one of the left-side extension portion 10L folded with the left-side fold line LB as a crease and the right-side extension portion 10R folded with the right-side fold line RB as a crease when viewed in the front-rear direction.

[0158] That is, at least one of the left-side extension portion 10L and the right-side extension portion 10R (both in the present embodiment) folded to the inside in the left-right direction is packaged in a state of overlapping the warming agent 26 in the front-rear direction, and thus the emission of the vaporized warming agent 26 (from the non-skin-side sheet 24c) in the front-rear direction can be suppressed.

[0159] In addition, in the present embodiment, at least one of the left-side extension portion 10L folded with the left-side fold line LB as a crease and the right-side extension portion 10R folded with the right-side fold line RB as a crease is folded in the up-down direction with the longitudinal fold line BL as a crease, and in the packaged state, at least a portion of the warming agent 26 overlaps at least one of the left-side extension portion 10L and the right-side extension portion 10R folded in the up-down direction when viewed in the front-rear direction.

[0160] That is, at least one of the left-side extension portion 10L and the right-side extension portion 10R (both in the present embodiment) folded in the up-down direction is packaged in a state of overlapping the warming agent 26 in the front-rear direction in addition to at least one of the left-side extension portion 10L and the right-side extension portion 10R (both in the present embodiment) folded to the inside in the left-right direction, and thus the emission of the vaporized warming agent 26 (from the non-skin-side sheet 24c) in the front-rear direction can be further suppressed.

[0161] In addition, in the present embodiment, the pair of leg-opening portions lb on both sides in the left-right direction, and at least a portion of the pair of leg-opening portions lb overlaps at least one of the left-side extension portion 10L and the right-side extension portion 10R in the up-down direction in the packaged state.

[0162] That is, at least one of the left-side extension portion 10L and the right-side extension portion 10R (both in the present embodiment) overlaps the pair of leg-opening portions lb in the up-down direction, and thus functions as a cover for the pair of leg-opening portions lb in the packaged state, and thus the emission of the vaporized warming agent 26 can be suppressed.

[0163] Further, in the present embodiment, a pair of three-dimensional gathers 50 is provided along the up-and-down direction at both end portions in the left-and-right direction of the absorbent main body 20, and the pair of three-dimensional gathers 50 has an adhesive region 54 for fixing the pair of three-dimensional gathers 50 at the respective front side upper end portion and rear side upper end portion, and at least a part of the adhesive region 54 is folded along the up-and-down direction with the longitudinal fold line BL as a crease in the packed state.

[0164] The adhesive region 54 is high in rigidity compared to a region other than the adhesive region 54, and therefore, if the adhesive region 54 is taken as a crease of the longitudinal fold line BL, the absorbent article 1 can be firmly folded along the up-and-down direction. That is, the crease of the longitudinal fold line BL further functions as a cover of the waist opening portion la in the packed state, and the discharge of the vaporized warming agent 26 can be further suppressed. Further, the absorbent article 1 is firmly folded along the up-and-down direction, and therefore, the habitual bending of the absorbent main body 20 can be more strongly formed.

[0165] Further, in the present embodiment, a turning portion 40 in which the density of the absorbent core 22 is higher than the density of the surroundings of the absorbent core 22 is provided in the absorbent core 22, and at least a part of the turning portion 40 is folded along the up-and-down direction with the longitudinal fold line BL as a crease in the packed state.

[0166] The turning portion 40 is high in rigidity compared to a region other than the turning portion 40, and therefore, if the turning portion 40 is taken as a crease of the longitudinal fold line BL, the absorbent article 1 can be firmly folded along the up-and-down direction. That is, the crease of the longitudinal fold line BL further functions as a cover of the waist opening portion la in the packed state, and the discharge of the vaporized warming agent 26 can be further suppressed. Further, the absorbent article 1 is firmly folded along the up-and-down direction, and therefore, the habitual bending of the absorbent main body 20 can be more strongly formed.

[0167] Further, in the present embodiment, a crotch elastic member 30 is provided along the up-and-down direction at the central portion in the left-and-right direction of the absorbent main body 20, and the crotch elastic member 30 is not folded along the up-and-down direction with the longitudinal fold line BL as a crease in the packed state.

[0168] That is, the crotch elastic member 30 does not form a habitual bending along the longitudinal fold line BL, and therefore, the adverse effect on the stretch function of the crotch elastic member 30 can be suppressed.

[0169] Further, in the present embodiment, the absorbent main body 20 is provided with a first skin side sheet 24a located at the position closest to the skin side and a second skin side sheet 24b located between the first skin side sheet 24a and the absorbent core 22 as skin side sheets, and the warming agent 26 is provided at at least one of the non-skin side of the first skin side sheet 24a and the second skin side sheet 24b.

[0170] If the thermo-sensitive agent 26 is provided on the inner surface (the surface on the skin side) of the absorbent article 1, the thermo-sensitive agent 26 directly contacts the wearer, and thus the stimulation to the wearer is too strong, which can cause skin problems such as redness, itching, or rash on the skin of the wearer. In addition, if the thermo-sensitive agent 26 is provided on the outer surface (the surface on the non-skin side) of the absorbent article 1, even if the non-skin side sheet 24c allows the gas to pass through, the thermo-sensitive agent 26 is too far from the skin of the wearer, and thus the effect of the thermo-sensitive agent 26 cannot be sufficiently exerted.

[0171] In view of this, in the present embodiment, the thermo-sensitive agent 26 is not directly in contact with the skin of the wearer, and is applied to the non-skin side of the first skin side sheet 24a closest to the skin of the wearer. That is, the inappropriate position (the inner surface and the outer surface) in the thickness direction of the thermo-sensitive agent 26 can be avoided, and since the thermo-sensitive agent 26 is also close to the skin of the wearer, the temperature of the thermo-sensitive agent 26 rises due to the body temperature of the wearer, and thus the vaporization of the thermo-sensitive agent 26 is promoted, and the effect of the thermo-sensitive agent 26 can be improved.

[0172] ==Other Embodiments==

[0173] The above-described embodiments are for the purpose of facilitating understanding of the present application, and are not intended to limit the explanation of the present application. The present application can be changed and improved without departing from the spirit thereof, and it is self-evident that equivalents thereof are included in the present application.

[0174] In addition, in the above-described embodiment, for the pant-type absorbent article 1, as shown in Figs. 1 and 2, first, the left side extension portion 10L (the right side extension portion 10R) is folded back toward the back side with the left side fold line LB (the right side fold line RB) as a crease, and next, folded in the up-and-down direction with the longitudinal fold line BL as a crease so as to face the members on the back side, and thus packaged, but is not limited thereto. For example, for the pant-type absorbent article 1, first, the left side extension portion 10L (the right side extension portion 10R) can be folded back toward the belly side with the left side fold line LB (the right side fold line RB) as a crease, and next, folded in the up-and-down direction with the longitudinal fold line BL as a crease so as to face the members on the belly side, and thus packaged. Fig. 8 Fig. 6 In addition, in the above-described embodiment, for the pant-type absorbent article 1, as shown in Figs. 1 and 2, first, the left side extension portion 10L (the right side extension portion 10R) is folded back toward the back side with the left side fold line LB (the right side fold line RB) as a crease, and next, folded in the up-and-down direction with the longitudinal fold line BL as a crease so as to face the members on the back side, and thus packaged, but is not limited thereto. For example, for the pant-type absorbent article 1, first, the left side extension portion 10L (the right side extension portion 10R) can be folded back toward the belly side with the left side fold line LB (the right side fold line RB) as a crease, and next, folded in the up-and-down direction with the longitudinal fold line BL as a crease so as to face the members on the belly side, and thus packaged.

[0175] According to the pant-type absorbent article 1, as with the above-described embodiment, the crease of the longitudinal fold line BL functions as a cover of the waist opening portion la in the packaged state, and thus the discharge of the vaporized thermo-sensitive agent 26 can be suppressed.

[0176] In addition, the back side waist member 10b has a portion covering the buttocks, and thus generally has a larger shape (the hatched portion shown in Fig. 2) than the front side waist member 10f when viewed from above. Fig. 6

[0177] ​​That is, if the left protruding portion 10L (right protruding portion 10R) is folded toward the ventral side with the left fold line LB (right fold line RB) as a crease, the portion of the left protruding portion 10L (right protruding portion 10R) that covers the buttocks (the portion shown by the hatched portion) overlaps in a manner to block the pair of leg-hole opening portions lb, thus functioning as a firm cover for the pair of leg-hole opening portions lb in the packed state, and the discharge of the gaseous warming agent 26 can be further suppressed. ​

[0178] Further, the habitual bend of the front side (ventral side) of the absorbent body 20 is formed in a shape that protrudes from the non-skin side toward the skin side, and thus the habitual bend can strongly abut against the lower abdomen. That is, the warming agent 26 located at the habitual bend is close to the wearer's skin, and thus the temperature of the warming agent 26 rises due to the wearer's body temperature, and the gassing of the warming agent 26 is promoted, and the effect of the warming agent 26 on the lower abdomen can be improved.

[0179] On the other hand, the habitual bend of the rear side (dorsal side) of the absorbent body 20 is formed in a shape that protrudes from the skin side toward the non-skin side, and thus the warming agent 26 applied to the habitual bend is away from the sacrum. That is, the irritation of the warming agent 26 to the wearer is suppressed, and the gassing of the warming agent 26 is suppressed, and thus the warming effect can be long-lasting. Further, the habitual bend easily follows the bulge of the sacrum (buttocks), and thus the feeling of oppression during wearing can be suppressed.

[0180] Further, in the above embodiment, the packaging of the pant-type absorbent article 1 is individual packaging in which one pant-type absorbent article 1 is folded and put into one packaging container, but is not limited thereto, and can be multiple packaging in which a plurality of pant-type absorbent articles 1 are folded and put into one packaging container.

[0181] According to the multiple packaging, for example, a situation is considered in which, in order to use one pant-type absorbent article 1, one or a plurality of pant-type absorbent articles 1 are stored in the opened packaging container after the packaging container is opened. In this situation, the gaseous warming agent 26 existing in the space inside the absorbent article 1 easily discharges. That is, if the pant-type absorbent article 1 is folded as in the above embodiment, the discharge of the gaseous warming agent 26 can be suppressed compared to the case in which the pant-type absorbent article 1 is not folded.

[0182] Further, in the above embodiment, the warming agent 26 is used as an example of the volatile substance, but is not limited to the warming agent 26, and for example, a cooling agent can be used. In the case of using a cooling agent, the discomfort caused by the wearer's stuffiness and stickiness can be reduced.

[0183] ​That is, with the absorbent article 1 provided with the cooling agent (temperature sensing agent 26), the volatile substance can improve the cooling effect (temperature sensing effect) on the wearer compared to the case other than the cooling agent (temperature sensing agent 26).

[0184] In addition, as for the mechanism (mechanism) of the temperature sensing agent 26 described above to vaporize and exert the effect, the cooling agent, the fragrance described later is the same, so the description is omitted.

[0185] As examples of the cooling agent, menthol (e.g., l-menthol) and its derivatives (e.g., menthyl lactate), methyl salicylate, camphor, essential oils derived from plants (e.g., peppermint, eucalyptus), and the like can be listed. In addition, the cooling agent, like the temperature sensing agent 26, is preferably stimulating the temperature-sensitive TRP channel.

[0186] In addition, in the above embodiment, as an example of the volatile substance, the temperature sensing agent 26 is used, but is not limited to the temperature sensing agent 26, and for example, a fragrance can be used. The fragrance can be used instead of the temperature sensing agent 26, or can be used together with the temperature sensing agent 26. As the fragrance, the same fragrance as the fragrance used in the past in the technical field can be used.

[0187] In addition, as the fragrance, particularly in the case of a green herbal style fragrance (green herbal type aroma), no physical stimulation is given to the body, and also, without oral administration, it is possible to safely and simply alleviate the symptoms of discomfort, particularly mental. In addition to this, a sense of comfort can also be obtained.

[0188] The green herbal type aroma is a fragrance containing a green odor or a herbal odor. The green odor is a fresh fragrance of grass and tender leaves. The herbal odor (herbal note) is a fragrance characterized by the note of medicinal plants in the natural environment where herbs are used.

[0189] The perfume composition containing a perfume having a green, herbaceous type of aroma preferably contains one or more than two kinds of perfume selected from the group consisting of 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, methyl phenyl methyl acetate, 2-methyl-3-(3,4-methylenedioxyphenyl)-propanal (IFF name, heliotropin aldehyde), 3(4)-(5-ethyl bicyclo[2,2,1]heptyl-2)-cyclohexanol, 2-pentyloxy allyl glycolate (IFF name, gaultheria), 4-methyl-3-decen-5-ol (Givaudan name, methyl decenol), hexanal, 2,4-dimethyl-3-cyclohexenyl carboxaldehyde (IFF name, ligustral), and phenyl acetaldehyde. As these perfumes, commercially available products can be used. The perfume containing them mainly produces a green, herbaceous aroma.

[0190] The perfume composition containing a perfume having a green, herbaceous type of aroma preferably further contains one or more than two kinds of perfume selected from the group consisting of l-menthol, 1,8-cineol, methyl salicylate, citronellal, camphor, borneol, isobomyl acetate, terpinyl acetate, eugenol, anethole, 4-methoxy benzyl alcohol, and estragol. The perfume containing them mainly produces a green, herbaceous aroma.
