= = 1 st embodiment= = = =1 st embodiment

As an example of the absorbent article having a volatile material in embodiment 1, a pants-type absorbent article 1 having Wen Ganji (corresponding to a volatile material) described later will be described. In the following description, the absorbent article 1 for physiological use 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 application is not limited to physiological use.

Fig. 1 is a schematic perspective view of a pants-type absorbent article 1, and fig. 2 is a plan view of the pants-type absorbent article 1 in an expanded state.

In the pants-type state shown in fig. 1, the absorbent article 1 has a "vertical direction", a "horizontal direction", and a "front-rear direction" which intersect with each other. The longitudinal direction of the paper surface in fig. 1 is set to the up-down direction, the upper side (lower side) of the paper surface is set to the up-down direction ("down"), and the left side (right side) of the paper surface is set to the left (right) of the left-right direction in the left-right direction. In the front-rear direction, the side that becomes the abdomen side of the wearer when worn is referred to as the "front side", and the side that becomes the back side of the wearer is referred to as the "back side".

In the unfolded state of the absorbent article 1 shown in fig. 2 (state of expansion on a plane before the pants-type absorbent article 1 is formed into a pants-type), the absorbent article 1 has a "longitudinal direction", a "width direction", and a "thickness direction" which intersect each other. The longitudinal direction of the paper surface of fig. 2 is defined as the longitudinal direction, the upper side (lower side) of the paper surface is defined as the longitudinal direction "front (web side)" ("rear (back side)"), the direction orthogonal to the longitudinal direction on the paper surface is defined as the width direction, and the left side (right side) of the paper surface is defined as the width direction left (right side). The direction perpendicular to the longitudinal direction and the width direction (the direction penetrating the paper surface) is referred to as the thickness direction, and the side in contact with the skin of the wearer in the thickness direction is referred to as the "skin side", and the opposite side is referred to as the "non-skin side".

In addition, a plan view (for example, fig. 2) of the present embodiment shows an extended state of the object. Here, the "extended state" refers to a state in which the members shown in the plan view are extended to be free from wrinkles by extending the respective elastic bodies (for example, crotch rubber bands 30, stretchable sheets, and the like described later) provided in the absorbent article 1. For example, fig. 2 shows a state in which the waist member 10 and the absorbent main body 20, which are described later, constituting the absorbent article 1 are elongated until the dimensions thereof match or are close to the dimensions of the individual members.

The absorbent article 1 of the present embodiment includes the waistline member 10 and the absorbent body 20, and a process of producing the waistline member 10 and the absorbent article 1 into a pants type will be described below. Then, the absorbent main body 20 will be described later. In the present embodiment, the absorbent body 20 is provided with a temperature sensitive agent 26.

As shown in fig. 2, the waistline member 10 has a substantially hourglass shape in plan view in the deployed state. That is, the central portion in the longitudinal direction is recessed inward in the width direction, and the recessed portions form a pair of leg hole openings 1b shown in fig. 1 when the pants-type diaper is formed. The waistline member 10 includes an unillustrated stretchable sheet so as to stretch in the width direction. Therefore, the waistline member 10 of the pants-type absorbent article 1 stretches in the left-right direction.

The waistline member 10 includes a front waistline member 10f located forward of the center fold line CL located in the center of the absorbent article 1 in the longitudinal direction, and a rear waistline member 10b located rearward of the center fold line CL. The front waistline member 10f (rear waistline member 10 b) has a waistline front end portion 10ff (waistline rear end portion 10 bf) along the width direction at the front (rear) end portion, and front joining portions 10fe (rear joining portions 10 be) along the length direction provided at both the left and right end portions (both are oblique lines in fig. 2).

In the process of producing the absorbent article 1 into the pants type, first, the absorbent main body 20 is disposed at a predetermined position of the waistline member 10 in the unfolded state, and the absorbent article 1 in the unfolded state is produced. That is, the non-skin-side surface of the absorbent main body 20 is used as a joining surface, and the joining surface is placed on and joined to a predetermined position of the waist member 10 in the unfolded state. That is, the waistline member 10 is superimposed on the non-skin side of the absorbent main body 20 in the thickness direction.

Then, the absorbent main body 20 and the waistline member 10 in the developed state are folded in the longitudinal direction. That is, the absorbent main body 20 and the waist member 10 are folded in the longitudinal direction so that the skin side of the front waist member 10f and the skin side of the rear waist member 10b face each other with the center folding line CL shown in fig. 2 as a fold line.

In this way, the front side joint portion 10fe and the rear side joint portion 10be of the waist member 10 come close to each other, and therefore the left and right front side joint portions 10fe and the rear side joint portion 10be are joined to each other.

That is, the left and right end portions of the waistline member 10 are joined in the longitudinal direction, and therefore the waistline front end portion 10ff and the waistline rear end portion 10bf form a waistline opening portion 1a on the upper side of the waistline member 10.

The waistline member 10 includes a left protruding portion 10L located on the outer side of the absorbent main body 20 in the width direction (on the left side of the broken line shown by LL in fig. 2) and a right protruding portion 10R located on the outer side of the absorbent main body 20 in the width direction (on the right side of the broken line shown by RL in fig. 2).

The pants-type absorbent article 1 has the following structure: the waistline member 10 is abutted against the front side (abdomen) and the rear side (back) of the body of the wearer (abutted against the waistline of the wearer), and does not fall down when worn by the expansion and contraction (fastening to the body) of the waistline member 10 mainly in the left-right direction. Accordingly, the absorbent body 20 joined to the waistline member 10 is supported by the waistline member 10 in the up-down direction in a state of being in contact with the crotch of the wearer (a portion where the absorbent body 20 is in contact with the skin of the wearer when worn, and a portion from the lower abdomen to the sacrum portion of the buttocks (buttocks)) via the crotch.

That is, the absorbent article 1 has an abdomen, a back, and a crotch, is a pants-type having a waist opening 1a and a pair of leg hole openings 1b, and is supported by a stretchable sheet or the like provided in the waist member 10 so as not to fall down when worn.

In addition, "abutting" refers to touching and contacting, and if at least a portion of a member abuts against a wearer, the member comes into contact with the wearer. For example, a state in which the stretchable portion in the waistline member 10 is in contact with the wearer, and the non-stretchable portion is not in contact with the wearer is a state in which the waistline member 10 is in contact with the wearer.

As a joining method for joining the absorbent main body 20 and the waistline member 10 and the like, for example, known joining methods such as an adhesive, heat sealing, ultrasonic sealing, and a combination thereof can be exemplified.

With respect to the absorbent main body 20>

Next, the absorbent body 20 will be described with reference to fig. 3 to 5. Fig. 3 is a top view of the absorbent body 20, and fig. 4 is a view A-A of fig. 3 and is a schematic cross-sectional view of the absorbent body 20. With respect to fig. 5, which will be described later.

The absorbent body 20 of the present embodiment is a physiological absorbent body 20, and is a so-called sanitary napkin. That is, the absorbent body 20 includes a liquid-absorbent core 22, and the outer peripheral surface of the absorbent core 22 is covered with a core wrap sheet 22a.

The absorbent core 22 is formed by molding a liquid absorbent material into a predetermined shape, and in the present embodiment, is formed into a substantially rectangular shape in a plan view (a diagonal view of fig. 3) and a convex shape in a cross-section (a hatched portion of fig. 4). As the liquid-absorbent material, a liquid-absorbent fiber such as pulp fiber containing a super absorbent polymer (so-called SAP) and the like can be exemplified. As the core wrap sheet 22a, a liquid-permeable sheet such as tissue paper or nonwoven fabric can be exemplified. In addition, the core wrap sheet 22a may be omitted.

As shown in fig. 4, the absorbent main body 20 includes, in addition to the absorbent core 22, a 1 st skin side sheet 24a, a 2 nd skin side sheet 24b, and a temperature-sensitive agent 26 on the skin side of the absorbent core 22, and includes, on the non-skin side of the absorbent core 22, a crotch band 30 (corresponding to an elastic member) and a non-skin side sheet 24c along the longitudinal direction.

The absorbent main body 20 includes side sheets 24d, and the side sheets 24d are provided so as to extend from the position closest to the non-skin side in the thickness direction to the position closer to the skin than the 1 st skin side sheet 24a at both ends in the width direction of the absorbent main body 20, and are folded back to the non-skin side. A part of the side sheet 24d extending to the skin side forms a three-dimensional gather 50 (corresponding to a leakage preventing wall) described later. That is, a pair of three-dimensional gathers 50 formed by the side panels 24d are provided in the up-down direction at both ends in the width direction of the absorbent main body 20.

In addition, a plurality of turning portions 40 (corresponding to compressed grooves) are formed on the skin side of the absorbent main body 20 (absorbent core 22).

In order to prevent the temperature sensitive agent 26 from leaking outward, the three-dimensional gather 50 is preferably made of the same number of nonwoven fabrics from the fulcrum 50B to the apex 50S, and more preferably 2 or more sheets.

The 1 st skin-side sheet 24a is a liquid-permeable sheet member that can be brought into contact with the skin of the wearer when worn, and is formed of, for example, a hydrophilic hot air nonwoven fabric, a spunbond nonwoven fabric, or the like. The 2 nd skin side sheet 24b is a sheet member having substantially the same function and structure as the 1 st skin side sheet 24a, and is laminated on the non-skin side surface of the 1 st skin side sheet 24 a.

That is, the absorbent main body 20 includes, as skin side sheets, a 1 st skin side sheet 24a positioned closest to the skin side and a 2 nd skin side sheet 24b positioned between the 1 st skin side sheet 24a and the absorbent core 22. The 2 nd skin side sheet 24b may not be necessarily provided in the absorbent main body 20.

The non-skin side sheet 24c may be a liquid impermeable sheet, and examples thereof include a polyethylene film and a polypropylene film. The size of the 1 st skin-side sheet 24a and the non-skin-side sheet 24c is a size covering the entire absorbent core 22.

The side sheet 24d is formed of, for example, a hot air nonwoven fabric, a spunbond nonwoven fabric, or the like, because it is in local contact with the skin of the wearer when worn.

Wen Ganji 26 to alleviate the symptoms of physiological pain and coldness of the wearer, contains a temperature-sensitive stimulant for warming the wearer subjected to stimulation by applying stimulation to the wearer's temperature-sensitive stimulation, and is provided in a state of being mixed with a solvent which is a volatile substance.

Further, wen Ganji is applied between the 1 st skin-side sheet 24a and the 2 nd skin-side sheet 24b in the thickness direction (at least one of the non-skin side of the 1 st skin-side sheet 24a and the skin side of the 2 nd skin-side sheet 24 b. In this embodiment, the non-skin side of the 1 st skin-side sheet 24 a) (the darkened portion of fig. 4) and is not applied at a place where it is in contact with the skin of the wearer. Wen Ganji 26 of the present embodiment is vaporized to reach the skin of the wearer, and exerts its main temperature-sensitive effect. The vaporization of the temperature sensitive agent 26 will be described in detail later.

Further, wen Ganji can also be provided on the absorbent core 22. That is, the temperature sensitive agent 26 may be provided in at least one of the absorbent core 22 and the skin side sheet (the 1 st skin side sheet 24a and the 2 nd skin side sheet 24 b).

The temperature-sensitive stimulant is preferably a plant-derived compound from the viewpoint of the feeling of mind of the wearer. Examples of the thermal stimulant include capsaicin (capsiside), capsaicin (LD 50:47mg/kg, molecular weight: 305), capsaicin (dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, synthetic capsaicin, etc.), capsanthin, benzyl nicotinate (LD 50:2188mg/kg, molecular weight: 213), beta-butoxyethyl nicotinate, N-acyl vanillylamide, vanillin nonanoate, polyhydric alcohol, chilli powder, capsicum tincture, capsicum extract, vanillyl ether of nonanoic acid, vanillyl alkyl ether derivatives (e.g., vanillyl diethyl ether, vanillyl butyl ether (LD 50:4900mg/kg, molecular weight: 210), vanillyl amyl ether, vanillyl hexyl ether), isovanillyl alkyl ether, ethyl vanillyl alkyl ether, resveratrol derivatives, substituted benzyl alcohol alkyl ethers, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, ginger oil, gingerol (LD 50:250 mg/kg), oil, pyrrolidone, and combinations thereof.

The solvent is not particularly limited as long as it can contain a temperature-sensitive stimulant, and examples thereof include a lipophilic solvent and a hydrophilic solvent. The solvent is capable of dissolving, dispersing, etc., the temperature sensitive stimulant.

Examples of the lipophilic solvent include oils and fats, for example, natural oils (for example, fatty acid esters such as triglycerides, coconut oil, linseed oil, and tri (caprylic/capric) glycerides), hydrocarbons (for example, paraffin, and liquid paraffin).

Examples of the hydrophilic solvent include water and alcohols. Examples of the alcohol include lower alcohols such as methanol, ethanol, ethylene glycol, and glycerol, and higher alcohols such as octanol, lauryl alcohol, and myristyl alcohol.

In addition, wen Ganji preferably stimulates temperature sensitive TRP channels. For example, TRPV1, which is one of the temperature sensitive TRP channels, is activated by stimulation of capsaicin, acid, etc. Moreover, when TRPV1 of the wearer is activated, heat generation is caused via the sympathetic nervous system (heat generation in the body of the wearer).

That is, it is preferable to warm the wearer without heating the wearer itself to a high temperature, such as capsaicin, rather than heating the wearer itself to a high temperature, such as a portable disposable warmer. In this way, the wearer can feel cool and warm without being burned or burned by the low temperature.

Further, wen Ganji is less effective if it does not directly contact the skin of the wearer. That is, for example, if a volatile substance such as a perfume is a gas, the effect of suppressing the peripheral odor can be exerted, but Wen Ganji directly contacts the skin of the wearer after vaporization, and exerts its main effect. Therefore, the wearer can gradually feel the effect of the temperature-sensitive agent 26 at the skin by bringing the Wen Ganji with the skin of the wearer via the nonwoven fabric or the like.

Fig. 5 is a view showing the coated region 26p and the uncoated region 26n of the temperature-sensitive agent 26. As shown in fig. 5, wen Ganji is applied to a pair of application regions 26p (hatched portions in fig. 5) having a predetermined dimension in the width direction and extending in the up-down direction (longitudinal direction). Therefore, a non-coated region 26n along the longitudinal direction in which the temperature sensitive agent 26 is not coated is provided at the widthwise center of the absorbent main body 20.

In the present embodiment, a non-coating region 26n having a width of 15mm is provided at the center in the width direction of the absorbent main body 20, and a pair of coating regions 26p having a width of 25mm are provided on both outer sides in the width direction of the non-coating region 26n. The coated region 26p and the uncoated region 26n are continuous regions from the front end to the rear end in the longitudinal direction of the absorbent main body 20.

Next, vaporization of the temperature sensitive agent 26 will be described. The solvent of the temperature sensitive agent 26 is gasified in a state of containing the temperature sensitive stimulant. That is, the solvent containing the temperature-sensitive stimulant evaporates to reach the skin of the wearer, and the reached temperature-sensitive stimulant stimulates the temperature sensation of the wearer. That is, in the present embodiment, even if the Wen Ganji is not directly contacted with the skin of the wearer, the vaporized temperature-sensitive agent 26 is vaporized, and the vaporized temperature-sensitive agent 26 is contacted with the skin of the wearer.

The amount of vaporization of the solvent increases or decreases according to the temperature change of the temperature-sensitive agent 26 caused by the transmission of the body temperature of the wearer or the like, and the magnitude of the expansion/contraction operation of the absorbent main body 20 in which the Wen Ganji is located (if the expansion/contraction is large, the temperature-sensitive agent 26 also moves to a large extent, and the amount of vaporization increases). That is, the amount of vaporization can be adjusted by adjusting the transfer of body temperature to the temperature-sensitive agent 26 (distance between Wen Ganji and the skin of the wearer, etc.), the expansion and contraction of the absorbent body 20 in which Wen Ganji is located (presence or absence of an elastic member, etc.), and the like. That is, the intensity of the temperature-sensitive stimulus felt by the wearer and the duration of time (the time for which the solvent evaporates) for which the effect of the temperature-sensitive agent is exerted can be adjusted.

As shown in fig. 3 and 4, the crotch rubber band 30 is provided from the front side, which is in contact with the lower abdomen, to the rear side, which is in contact with the buttocks, via the crotch portion, at the center portion in the left-right direction (width direction) of the absorbent main body 20. That is, the crotch band 30 is provided in the absorbent main body 20 along the up-down direction (longitudinal direction).

Further, since the crotch band 30 is cut for each absorbent article 1 after being joined to the non-skin-side sheet 24c in a continuously stretched state, the crotch band 30 in the non-joined portion is contracted toward the joined portion after the cutting, and the crotch band 30 in the non-stretched state is provided in the absorbent main body 20. That is, the crotch rubber band 30 is provided in an unstretched state at the front end of the crotch rubber band 30.

Since this portion has higher rigidity than the portion where the crotch rubber band 30 is not provided, when the absorbent article 1 is worn, it is difficult to collapse the shape of the absorbent main body 20 after the absorbent main body 20 is deformed into a cup shape (U-shape when viewed from the left-right direction in the pants-type). That is, in the pants-type absorbent article 1, for example, when a force for deforming the absorbent main body 20 is applied from the upper side in the vertical direction, if a portion of the crotch rubber band 30 in an unstretched state is provided, the portion has higher rigidity and is less likely to deform than a portion without the crotch rubber band 30, and therefore the shape of the absorbent main body 20 can be made less likely to collapse.

The crotch band 30 of the present embodiment is provided on the non-skin side of the non-skin side sheet 24c on the non-skin side of the absorbent core 22, but is not limited to this, and may be provided on the skin side of the non-skin side sheet 24c, or may be provided on the skin side of the absorbent core 22, in addition to the non-skin side.

The member for stretching and contracting the absorbent body 20 is not limited to the crotch rubber band 30, and a stretchable nonwoven fabric or a stretchable film may be used.

The turning portion 40 is formed in a concave shape that is concave from the skin side toward the non-skin side on the skin side of the absorbent main body 20 (absorbent core 22) as shown in fig. 4, when the absorbent main body 20 is deformed (becomes a deformed crease) along the body of the wearer when the wearer wears the absorbent article 1.

The concave shape of the turning portion 40 of the present embodiment 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 turn 40 is a compressed groove having a higher density of the absorbent core 22 than its surroundings.

In the present embodiment, as shown in fig. 3, a front turning portion 41 having a predetermined length in the width direction is provided at the front end portion in the longitudinal direction of the absorbent core 22, mainly at a portion where the lower abdomen portion is in contact when worn. The front-side turning portion 41 is mainly provided so that the absorbent main body 20 extends along the lower abdomen.

Further, a plurality of turning portions 42 paired in the width direction are provided at predetermined intervals at the rear side in the longitudinal direction of the front turning portion 41 at intervals. The pair of turning portions 42 are mainly provided in such a manner that the absorbent main body 20 is disposed along the crotch portion and the buttocks.

The depth of the concave portion of the turning portion 40 of the present embodiment is not constant, and the deformation of the absorbent body 20 is adjusted by adjusting the depth of the concave portion of the turning portion 40 with a shallower portion and a deeper portion.

The three-dimensional gather 50 is provided so as to abut on the periphery of the thighs of the wearer and to suppress leakage of liquid from the inside. That is, the three-dimensional gathers 50 are provided as a pair of three-dimensional gathers 50 corresponding to both legs, respectively, at both ends in the width direction of the absorbent main body 20.

As shown in fig. 3 and 4, the pair of three-dimensional gathers 50 have adhesive regions 54 (corresponding to the joining regions) to which an adhesive is applied to the front and rear upper end portions, respectively, and are joined to the 1 st skin-side sheet 24a in the adhesive regions 54. That is, the pair of three-dimensional gathers 50 have adhesive regions 54 for fixing the pair of three-dimensional gathers 50 at the respective front side upper end portions and rear side upper end portions.

Packaging of absorbent article 1

The absorbent article 1 of the present embodiment is folded after being produced into a pants-type shape, and 1 absorbent article 1 is packaged in 1 packaging container. That is, the absorbent article 1 is individually packaged, and is folded in the packaged state.

Hereinafter, the absorbent article 1 in a packaged state will be described with reference to fig. 6 to 9. Fig. 6 is a schematic plan view showing the longitudinal folding line BL, the left folding line LB, and the right folding line RB in a front view of the pants-type absorbent article 1. The upper view of fig. 7 is a schematic plan view of the pants-type absorbent article 1 in which the left side extension 10L and the right side extension 10R are folded inward, and the lower view is a schematic sectional view taken toward the side B-B. The left view of fig. 8 is a schematic plan view of the pants-type absorbent article 1 folded in the up-down direction with the longitudinal folding line BL as a fold, and the right view is a schematic side view when the absorbent main body 20 is viewed from the right side. Fig. 9 is a plan view of the absorbent main body 20 showing the position of the longitudinal folding line BL of the absorbent main body 20.

As shown in fig. 7, in the absorbent article 1 of the present embodiment, after the left side extension portion 10L is folded inward (right side) on the left side folding line LB, the right side extension portion 10R is folded inward (left side) on the right side folding line RB, and then the absorbent article is put into the packaging container in a state of being folded in the up-down direction with the longitudinal folding line BL along the left-right direction as a crease.

That is, the absorbent article 1 has a left fold line LB as a fold line when at least a part of the left side extension portion 10L is folded to the right side and a right fold line RB as a fold line when at least a part of the right side extension portion 10R is folded to the left side.

In the present embodiment, as shown in fig. 7, each of the left projecting portion 10L and the right projecting portion 10R is folded back. In addition, the left side projecting portion 10L and the right side projecting portion 10R may be folded at any time.

In the state shown in fig. 7, the left projecting portion 10L and the right projecting portion 10R folded inward overlap the application region 26p when viewed in the front-rear direction. That is, in a state before the absorbent article 1 is folded in the up-down direction, at least a part of the temperature sensitive agent 26 overlaps at least one of the left protruding portion 10L folded with the left folding line LB as a fold and the right protruding portion 10R folded with the right folding line RB as a fold when viewed in the front-back direction.

In addition, in the pair of leg hole openings 1b, the left side projecting portion 10L and the right side projecting portion 10R overlap in the up-down direction (the range of 1bY shown in fig. 7). That is, the absorbent article 1 has a pair of leg hole openings 1b on both sides in the left-right direction, and at least a part of the pair of leg hole openings 1b overlaps at least one of the left side extension 10L and the right side extension 10R in the up-down direction in the packaged state.

In a state where the left side extension portion 10L and the right side extension portion 10R are folded inward in the left-right direction, as shown in fig. 8, the absorbent article 1 is folded in the up-down direction with the longitudinal folding line BL along the left-right direction as a fold. That is, at least one of the left projecting portion 10L folded with the left folding line LB as a fold and the right projecting portion 10R folded with the right folding line RB as a fold is folded in the up-down direction with the longitudinal folding line BL as a fold.

Since the absorbent article 1 is packaged in this state, the left side extension portion 10L and the right side extension portion 10R folded in the up-down direction overlap with Wen Ganji as viewed in the front-back direction. That is, in the absorbent article 1, at least a part of the temperature sensitive agent 26 overlaps at least one of the left side extension 10L and the right side extension 10R folded in the up-down direction when viewed in the front-back direction in the packaged state.

< position on longitudinal folding line BL >

Next, the positional relationship between the vertical position of the longitudinal folding line BL and the respective members and the like provided in the absorbent article 1 will be described. Specifically, the positional relationship between the adhesive regions 54 and the longitudinal folding lines BL of the absorbent main body 20, the temperature-sensitive agent 26 (application region 26 p), the crotch rubber band 30, the turning portions 40, and the pair of three-dimensional gathers 50 will be described.

As shown in fig. 6 and 7, the longitudinal folding line BL is located below the upper end of the absorbent main body 20 (the upper end of the rear upper end 20 Be) in a state before the absorbent article 1 is folded in the up-down direction with respect to the absorbent main body 20 and the longitudinal folding line BL. That is, in the packaged state, at least a part of the absorbent main body 20 is folded in the up-down direction with the longitudinal folding line BL as a crease.

As shown in fig. 8, the absorbent body 20 is folded in the vertical direction so that the non-skin side surface of the rear upper end portion 20Be of the absorbent body 20 faces the non-skin side surface of the absorbent body 20 which is located below the longitudinal folding line BL and is the front-rear side, in a state where the front upper end portion 20Fe of the absorbent body 20 and the rear upper end portion 20Be of the absorbent body 20 are overlapped in the thickness direction before the absorbent article 1 is folded in the vertical direction.

As shown in the schematic plan view of fig. 7, at least a part of the temperature sensitive agent 26 is provided below the longitudinal folding line BL in a state before the absorbent article 1 is folded in the up-down direction.

When the size of the upper and lower regions of the application region 26p is attempted to be viewed with the longitudinal folding line BL as a boundary, the application region 26p located above the longitudinal folding line BL is smaller than the application region 26p located below the longitudinal folding line BL in the state before the absorbent article 1 is folded in the up-down direction.

As shown in fig. 8, at least a part of the temperature sensitive agent 26 is provided so as to overlap the longitudinal folding line BL in a state where at least a part of the absorbent main body 20 is folded in the up-down direction with the longitudinal folding line BL as a fold.

As shown in fig. 9, the crotch rubber band 30 and the longitudinal folding line BL do not overlap when viewed in the front-rear direction. That is, in the packaged state, the crotch rubber band 30 is not folded in the up-down direction with the longitudinal folding line BL as a fold.

As shown in fig. 9, the pair of turning portions 42 on the rear side of the absorbent main body 20 overlap the longitudinal folding line BL when viewed in the front-rear direction with respect to the turning portions 40 and the longitudinal folding line BL. That is, in the packaged state, at least a part of the turning portion 40 is folded in the up-down direction with the longitudinal folding line BL as a fold.

As shown in fig. 9, the adhesive regions 54 and the longitudinal folding lines BL of the pair of three-dimensional gathers 50 overlap the longitudinal folding lines BL on both sides of the front side and the rear side of the absorbent main body 20 when viewed in the front-rear direction. That is, in the packaged state, at least a part of the adhesive region 54 is folded in the up-down direction with the longitudinal folding line BL as a fold.

Validity of this embodiment

In the absorbent article 1 including the temperature sensitive agent 26, the Wen Ganji may be gasified and discharged during wearing, and the effect of the temperature sensitive agent 26 may not be sufficiently exhibited.

In contrast, the pants-type absorbent article 1 of the present embodiment includes: an absorbent main body 20 including a liquid-absorbent core 22 and skin-side sheets (a 1 st skin-side sheet 24a and a 2 nd skin-side sheet 24 b) provided closer to the skin than the absorbent core 22; and a waistline member 10 that is disposed so as to overlap the non-skin side of the absorbent main body 20 and that stretches in the left-right direction, wherein Wen Ganji is provided on at least one of the absorbent core 22 and the skin side sheet (the 1 st skin side sheet 24a and the 2 nd skin side sheet 24 b) (the 1 st skin side sheet 24a in this embodiment), and the pants-type absorbent article 1 is packaged in a state of being folded in the up-down direction with a longitudinal folding line BL along the left-right direction as a fold, and wherein at least a part of the temperature-sensitive agent 26 is provided at a position lower than the longitudinal folding line BL in a state before the pants-type absorbent article 1 is folded in the up-down direction. Therefore, the vaporized temperature-sensitive agent 26 can be suppressed from being discharged.

When the absorbent article 1 is folded in the vertical direction by the vertical folding line BL, the fold of the vertical folding line BL functions so as to be divided into a space (a hatched portion in the schematic cross-sectional view of fig. 7) which is the lower side of the vertical folding line BL and is the inner side (skin side) of the absorbent article 1 and a space which is the upper side of the vertical folding line BL and is the inner side (skin side) of the absorbent article 1 in a state before the absorbent article 1 is folded in the vertical direction. In this way, the space on the lower side of the longitudinal folding line BL partitioned by the longitudinal folding line BL is partitioned from the space on the outside of the absorbent article 1 communicating via the waist opening 1 a. That is, when the absorbent article 1 is folded in the vertical direction at the vertical folding line BL, the fold of the vertical folding line BL functions as a lid of the waist opening 1a in the packaged state, and therefore, the discharge of the vaporized thermal sensation agent 26 can be suppressed.

In the present embodiment, the predetermined region of the absorbent main body 20 along the vertical direction has the application region 26p to which the temperature sensitive agent 26 is applied, and the application region 26p of the absorbent main body 20 above the longitudinal folding line BL is smaller than the application region 26p of the absorbent main body 20 below the longitudinal folding line BL in the state before the pants-type absorbent article 1 is folded in the vertical direction.

That is, the crease of the longitudinal crease line BL can function as a cover of the waistline opening portion 1a in the packaged state with respect to the area exceeding half of the application area 26 p. That is, the discharge of the vaporized temperature-sensitive agent 26 is further suppressed.

In the present embodiment, the longitudinal folding line BL is located below the upper end of the absorbent main body 20 (the upper end of the rear upper end portion 20 Be) in the state before the pants-type absorbent article 1 is folded in the up-down direction, and at least a part of the absorbent main body 20 is folded in the up-down direction with the longitudinal folding line BL as a fold in the packaged state.

According to this state, since the waist member 10 is folded in the up-down direction in a state where the rigidity is improved as compared with the case where only the waist member 10 is folded in the up-down direction, it is possible to form a habitual fold along the longitudinal folding line BL in the absorbent main body 20 and to firmly fold in the up-down direction. That is, the crease of the longitudinal crease line BL can function as a firm cover of the waistline opening portion 1a in the packaged state, and can further suppress the discharge of the vaporized volatile substance.

In the present embodiment, at least a part of the temperature sensitive agent 26 is provided so as to overlap the longitudinal folding line BL in a state where at least a part of the absorbent main body 20 is folded in the up-down direction with the longitudinal folding line BL as a fold.

When the absorbent main body 20 is packaged (held for a long period of time) while being folded about the longitudinal folding line BL, a habitual fold along the longitudinal folding line BL is formed in the absorbent main body 20. Further, when the temperature-sensitive agent 26 is applied to the habitual bend, a temperature-sensitive effect due to the shape of the habitual bend can be imparted to the wearer. That is, if the habitual fold is a shape protruding from the non-skin side to the skin side, the temperature sensitive agent 26 approaches the skin of the wearer, so that the temperature of the temperature sensitive agent 26 increases by the body temperature of the wearer to promote vaporization thereof, and the effect of the temperature sensitive agent 26 can be improved. Further, if the habitual fold is a shape protruding from the skin side to the non-skin side, the temperature-sensitive agent 26 is away from the skin of the wearer, so that the irritation of Wen Ganji to the wearer is suppressed, and the vaporization of the temperature-sensitive agent 26 is suppressed, so that the temperature-sensitive effect can be sustained for a long period of time.

In the present embodiment, the absorbent main body 20 is folded in the vertical direction so that the non-skin side surface of the rear side upper end portion 20Be of the absorbent main body 20 in the state before the pants-type absorbent article 1 is folded in the vertical direction is opposed to the non-skin side surface of the absorbent main body 20 on the rear side in the front-rear direction below the longitudinal folding line BL.

That is, since the habitual fold protruding from the non-skin side to the skin side is formed in the sacral portion of the wearer, and Wen Ganji located in the habitual fold is located close to the sacral portion of the wearer, the temperature of the temperature sensor 26 increases by the body temperature of the wearer to promote vaporization thereof, and the effect of the temperature sensor 26 can be improved in the sacral portion.

In the present embodiment, the front upper end portion 20Fe of the absorbent main body 20 and the rear upper end portion 20Be of the absorbent main body 20 in a state before the pants-type absorbent article 1 is folded in the up-down direction are folded in the up-down direction so that the non-skin side surface of the rear upper end portion 20Be of the absorbent main body 20 faces the non-skin side surface of the absorbent main body 20 on the rear side in the front-rear direction below the longitudinal folding line BL in a state where the front upper end portion 20Fe and the rear upper end portion 20Be of the absorbent main body 20 overlap in the thickness direction.

That is, the absorbent main body 20 is folded in the up-down direction in a state where the rigidity is improved, and therefore can be folded firmly in the up-down direction, as compared with the case where only the rear side or the front side is folded in the up-down direction. That is, the fold of the vertical fold line functions as a firm cover for the waist opening 1a in the packaged state, and can further suppress the discharge of the vaporized volatile material.

Further, the front (abdomen) absorbent main body 20 is formed with a habitual fold protruding from the skin side to the non-skin side. This habitual bending keeps Wen Ganji away from the skin of the wearer, thereby suppressing Wen Ganji irritation to the wearer and suppressing vaporization of the temperature sensitive agent 26, and thus enabling the temperature sensitive effect to be sustained for a long period of time. In addition, since habitual bending tends to bulge along the lower abdomen, the feeling of compression during wearing can be suppressed.

In the present embodiment, the waistline member 10 includes a left side projecting portion 10L located on the left side of the left side end of the absorbent main body 20 and a right side projecting portion 10R located on the right side of the right side end of the absorbent main body 20, and the pants-type absorbent article 1 includes a left fold line LB as a fold line when at least a part of the left side projecting portion 10L is folded to the right side and a right fold line RB as a fold line when at least a part of the right side projecting portion 10R is folded to the right side, and at least a part of the temperature-sensitive agent 26 overlaps at least one of the left side projecting portion 10L folded with the left side fold line LB as a fold line and the right side projecting portion 10R folded with the right side fold line RB as a fold line when viewed in the front-back direction in a state before the pants-type absorbent article 1 is folded in the up-down direction.

That is, at least one (in the present embodiment, both) of the left side projecting portion 10L and the right side projecting portion 10R folded inward in the left-right direction is packaged in a state of being overlapped with the Wen Ganji in the front-rear direction, so that the discharge of the vaporized Wen Ganji (discharged from the non-skin side sheet 24 c) in the front-rear direction can be suppressed.

In the present embodiment, at least one of the left extending portion 10L folded with the left folding line LB as a fold and the right extending portion 10R folded with the right folding line RB as a fold is folded in the up-down direction with the longitudinal folding line BL as a fold, and at least a part of the temperature sensitive agent 26 overlaps at least one of the left extending portion 10L and the right extending portion 10R folded in the up-down direction when viewed in the front-back direction in the packaged state.

That is, at least one (in the present embodiment, both) of the left projecting portion 10L and the right projecting portion 10R folded inward in the left-right direction is packaged in a state of being overlapped with the Wen Ganji 26 in the front-rear direction, in addition to at least one (in the present embodiment, both) of the left projecting portion 10L and the right projecting portion 10R folded upward and downward, so that the discharge of the vaporized Wen Ganji (discharged from the non-skin side sheet 24 c) in the front-rear direction can be suppressed even more.

In the present embodiment, a pair of leg hole openings 1b are provided on both sides in the left-right direction, and at least a part of the pair of leg hole openings 1b overlaps at least one of the left protruding portion 10L and the right protruding portion 10R in the up-down direction in the packaged state.

That is, at least one (in the present embodiment, both) of the left side projecting portion 10L and the right side projecting portion 10R overlaps the pair of leg hole openings 1b in the up-down direction, and functions as covers of the pair of leg hole openings 1b in the packaged state, so that the discharge of the vaporized thermal sensation agent 26 can be suppressed.

In the present embodiment, a pair of three-dimensional gathers 50 are provided along the vertical direction at both ends in the left-right direction of the absorbent main body 20, and the pair of three-dimensional gathers 50 have adhesive regions 54 for fixing the pair of three-dimensional gathers 50 at the front upper end and the rear upper end, respectively, and at least a part of the adhesive regions 54 are folded in the vertical direction with the longitudinal folding line BL as a fold in the packaged state.

Since the adhesive region 54 has higher rigidity than a region other than the adhesive region 54, the absorbent article 1 can be folded firmly in the up-down direction by using the adhesive region 54 as a crease of the longitudinal folding line BL. That is, the crease of the vertical fold line BL further functions as a lid of the waistline opening portion 1a in the packaged state, and can further suppress the discharge of the vaporized thermal sensation agent 26. Further, the absorbent article 1 is folded firmly in the up-down direction, and thus can form habitual bending of the absorbent main body 20 more strongly.

In the present embodiment, the absorbent core 22 is provided with the turning portion 40 having a density higher than that of the absorbent core 22, and at least a part of the turning portion 40 is folded in the up-down direction with the longitudinal folding line BL as a fold in the packaged state.

Since the turning portion 40 has higher rigidity than the region not being the turning portion 40, the absorbent article 1 can be folded firmly in the up-down direction by using the turning portion 40 as a crease of the longitudinal folding line BL. That is, the crease of the vertical fold line BL further functions as a lid of the waistline opening portion 1a in the packaged state, and can further suppress the discharge of the vaporized thermal sensation agent 26. Further, the absorbent article 1 is folded firmly in the up-down direction, and thus can form habitual bending of the absorbent main body 20 more strongly.

In the present embodiment, the crotch band 30 is provided at the center portion of the absorbent main body 20 in the left-right direction along the up-down direction, and in the packaged state, the crotch band 30 is not folded in the up-down direction with the longitudinal folding line BL as a fold.

That is, since the habitual bending along the longitudinal folding line BL is not formed in the crotch rubber band 30, adverse effects on the stretching function of the crotch rubber band 30 can be suppressed.

In the present embodiment, the absorbent main body 20 includes, as the skin-side sheet, the 1 st skin-side sheet 24a located closest to the skin and the 2 nd skin-side sheet 24b located between the 1 st skin-side sheet 24a and the absorbent core 22, and the Wen Ganji 26 is provided on at least one of the non-skin side of the 1 st skin-side sheet 24a and the 2 nd skin-side sheet 24 b.

When Wen Ganji is provided on the inner surface (skin-side surface) of the absorbent article 1, the temperature-sensitive agent 26 is in direct contact with the wearer, and thus the wearer is excessively stimulated, which causes skin problems such as redness, itching, and rash on the skin of the wearer. Further, if Wen Ganji is provided on the outer surface (non-skin-side surface) of the absorbent article 1, even if the non-skin-side sheet 24c transmits air, the Wen Ganji is too far from the skin of the wearer, and the effect of the temperature-sensitive agent 26 cannot be sufficiently exhibited.

In contrast, in the present embodiment, wen Ganji is applied to the non-skin side of the 1 st skin-side sheet 24a closest to the skin of the wearer without directly contacting the skin of the wearer. That is, since the temperature sensitive agent 26 is also located close to the skin of the wearer at an inappropriate position (inner surface and outer surface) in the thickness direction, the temperature of the temperature sensitive agent 26 increases due to the body temperature of the wearer, and vaporization thereof is promoted, and the effect of the temperature sensitive agent 26 can be improved.

Other embodiments of= = = = = = =

The above-described embodiments are provided to facilitate understanding of the present invention, and are not intended to limit the present invention. It is needless to say that the present invention can be modified and improved without departing from the spirit thereof, and equivalents thereof are included in the present invention.

In the above-described embodiment, as shown in fig. 7 and 8, the pants-type absorbent article 1 is packaged by first folding the left side extension portion 10L (right side extension portion 10R) back with the left side folding line LB (right side folding line RB) as a fold, and then folding the pants-type absorbent article back with the longitudinal folding line BL as a fold in the up-down direction so that the back members face each other. For example, in the pants-type absorbent article 1, the left side extension portion 10L (right side extension portion 10R) may be folded toward the abdomen with the left side folding line LB (right side folding line RB) as a fold, and then, the pants-type absorbent article may be packaged by being folded up and down with the longitudinal folding line BL as a fold so that the abdomen-side members face each other.

According to the pants-type absorbent article 1, as in the above-described embodiment, the crease of the longitudinal folding line BL functions as a cover of the waist opening 1a in the packaged state, and therefore, the discharge of the vaporized temperature-sensitive agent 26 can be suppressed.

Further, since the rear waistline member 10b has a portion covering the buttocks, it is generally larger in shape (hatched portion shown in fig. 6) than the front waistline member 10f in a plan view.

That is, when the left side extension portion 10L (right side extension portion 10R) is folded toward the abdomen side with the left side folding line LB (right side folding line RB) as a fold, the portion (hatched portion shown in fig. 6) of the left side extension portion 10L (right side extension portion 10R) covering the buttocks overlaps so as to close the pair of leg hole openings 1b, and therefore functions as a firm cover for the pair of leg hole openings 1b in the packaged state, and the discharge of the vaporized thermal sensitive agent 26 can be further suppressed.

Further, since the habitual fold on the front side (the abdominal side) of the absorbent main body 20 is formed in a shape protruding from the non-skin side toward the skin side, the habitual fold can be strongly brought into contact with the lower abdominal portion. That is, since the habitually folded Wen Ganji is positioned close to the skin of the wearer, the temperature of the temperature sensitive agent 26 increases by the body temperature of the wearer to promote vaporization, and the effect of the temperature sensitive agent 26 on the lower abdomen can be improved.

On the other hand, the habitual fold on the rear side (back side) of the absorbent main body 20 is formed in a shape protruding from the skin side toward the non-skin side, and therefore, wen Ganji applied to the habitual fold is located away from the sacrum portion. That is, the temperature sensing effect can be maintained for a long period of time because the irritation of Wen Ganji to the wearer is suppressed and the vaporization of the temperature sensing agent 26 is suppressed. In addition, since habitual bending tends to bulge along the sacrum (buttocks), the feeling of compression during wearing can be suppressed.

In the above embodiment, the package of the pants-type absorbent article 1 is an independent package in which 1 pants-type absorbent article 1 is folded and placed in 1 package container, but the present invention is not limited thereto, and a plurality of packages in which a plurality of pants-type absorbent articles 1 are folded and placed in 1 package container may be used.

From a plurality of packages, consider, for example, the following conditions: in order to use 1 pant-type absorbent article 1, after the packaging container is opened, 1 or more pant-type absorbent articles 1 are stored in the opened packaging container. In this case, the vaporized Wen Ganji which exists in the space inside the absorbent article 1 is an environment in which the vapor is easily discharged. That is, when the pants-type absorbent article 1 is folded as in the above-described embodiment, the discharge of the vaporized temperature-sensitive agent 26 can be suppressed as compared with the case of the unfolded pants-type absorbent article 1.

In the above embodiment, the temperature sensor 26 is used as an example of the volatile substance, but the temperature sensor is not limited to Wen Ganji, and for example, a cold sensor may be used. When the cold feeling agent is used, the uncomfortable feeling due to the stuffiness and stickiness of the wearer can be reduced.

That is, with the absorbent article 1 provided with the cold sensitizer (Wen Ganji), the volatile substance can improve the cold feeling effect (temperature feeling effect) of the wearer compared to the case other than the cold sensitizer (Wen Ganji).

Note that, the mechanism (mechanism) of the vaporization of Wen Ganji 26 described above to exert the effect is similar to that of a cold sensitizer and a perfume described later, and therefore, these descriptions are omitted.

Examples of the cold feeling agent include 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. In addition, the cryopensiting agent preferably stimulates a temperature sensitive TRP channel, as in Wen Ganji 26.

In the above embodiment, the temperature sensitive agent 26 is used as an example of the volatile substance, but the temperature sensitive agent is not limited to Wen Ganji, and for example, a perfume may be used. The fragrance may be used in place of the temperature sensing agent 26 or may be used with the temperature sensing agent 26. As the perfume, the same perfume as that conventionally used in the technical field can be used.

In addition, as a perfume, especially in the case of a green herbal perfume (green herbal fragrance), physical irritation to the body is not generated, and also, oral administration is not required, so that particularly psychologically uncomfortable symptoms can be safely and easily alleviated. In addition, comfort can be obtained.

Green herbal aromas are aromas that contain green group aromas (green notes) or herbal group aromas (herbal notes). The green fragrance refers to the fresh fragrance of grass and tender leaves. The herbal aroma (herbal note) refers to the note of the medicinal plant in nature in which herbs are used.

The perfume composition containing a perfume having a green herbal type fragrance preferably contains 1 or more kinds of perfumes selected from cis-3-hexenol, cis-3-hexenol formate, cis-3-hexenol acetate, cis-3-hexenol propionate, cis-3-hexenol butyrate, trans-2-hexenal, trans-2-hexenol acetate, hexyl acetate, methyl phenyl methyl acetate, 2-methyl-3- (3, 4-methylenedioxyphenyl) -propanal (IFF company name, heliotropin), 3 (4) - (5-ethylbicyclo [2, 1] heptyl-2) -cyclohexanol, allyl 2-pentoxyglycolate (IFF company name, graying ester), 4-methyl-3-decen-5-ol (Givaudan company name, methyl decenol), hexanal, 2, 4-dimethyl-3-cyclohexenyl formaldehyde (IFF company name, glossy privet aldehyde), and benzene. As these fragrances, commercially available ones can be used. Perfumes containing them mainly produce green fragrance.

The perfume composition containing a perfume having a green herbal type fragrance preferably further contains 1 or more than 2 kinds of perfumes selected from l-menthol, 1, 8-eucalyptol, methyl salicylate, citronellal, camphor, borneol, isobornyl acetate, terpinyl acetate, eugenol, anethole, 4-methoxybenzyl alcohol and artemia. Perfumes containing them mainly produce green fragrance.
