Due to the contraction of the elastic member 50S, a pair of three-dimensional gathers 50 are formed, the three-dimensional gathers 50 serve as a leak-proof wall, and the possibility of excrement leaking to the outside of the absorbent main body 20 in the left-right direction is reduced.

The inseam elastic member 30 is provided on the non-skin side of the absorber 22 and the non-skin side sheet 24c and on the skin side of the side sheet 24d, that is, between the non-skin side sheet 24c and the side sheet 24d in the thickness direction. Has been done. In the present embodiment, there are a plurality of (4) thread rubbers along the longitudinal direction, but the number is not limited to this, and may be a single number or a plurality of 4 or more threads, and is not limited to the thread rubber or the like, for example, expansion and contraction. It may be a strip-shaped elastic sheet having a property.

The warming agent 26 is provided inside the absorbent article 1, and the region where the warming agent 26 is provided (applied) is referred to as a coating region 26P. In FIG. 3 and the like, the coating region 26P is referred to as a coating region 26P for convenience. It is shown by hatching in the sand. The "inside of the absorbent article 1" means the skin side of the exterior back sheet 12, which is the outermost sheet of the absorbent article 1. In the present embodiment, it is applied to the non-skin side surface of the first skin side sheet 24a, and as shown in FIG. 3, the central portion of the absorber 22 in the left-right direction, the region excluding both end portions, and the absorber 22. The coating area 26P is provided over the entire area in the longitudinal direction. In particular, it is preferable to provide the warming agent 26 in the central portion of the absorber 22 in the left-right direction in order to bring it into contact with the wearer's excretion opening (vaginal opening) when worn. In the present embodiment, the coating area 26P is provided on the first skin side sheet 24a, but the present invention is not limited to this, and any arrangement can be made as long as it is inside the absorbent article 1. However, in order to make the wearer's skin feel the effect of the warming agent 26, it is preferable to provide the coating area 26P on the absorbent main body 20. Further, it is more preferable that the warming agent 26 is provided on the non-skin side surface of the first skin side sheet 24a. At this time, in the absorbent article 1, the amount of the warming agent 26 held by the first skin side sheet 24a is preferably larger than the amount of the warming agent 26 held by the side sheet 24d. Since the first skin side sheet 24a is a member of the absorbent body 20 at a position close to the wearer's skin when worn, the wearer can enjoy the effect of the warming agent 26 provided on the first skin side sheet 24a. It becomes easy to make you feel. On the other hand, by reducing the amount of the warming agent 26 held by the side sheet 24d, it is possible to reduce the possibility that the adhesiveness of the adhesive such as the hot melt adhesive that fixes the elastic member 50S to the side sheet 24d is lowered. be able to.

The warming agent 26 is a substance for alleviating the wearer's menstrual pain and cold symptoms, and is a substance provided with a warming stimulant that stimulates the wearer's temperature sensation. Since the warming agent 26 provided in the absorbent article 1 is applied in a state of being mixed with a volatile solvent, it is highly volatile.

The warmth stimulant is preferably a plant-derived compound from the viewpoint of the wearer's sense of security. Examples of the warming stimulant include capsicoside, capsaicin (LD50: 47 mg / kg, molecular weight: 305), capsaicinoids (dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin, nonibamide, etc.), capsantin, benzyl nicotinate, etc. (LD50: 2,188 mg / kg, molecular weight: 213), β-butoxyethyl nicotinate, N-acylwanylamide, vanillylamide nonanoic acid, polyhydric alcohol, capsaicin powder, capsaicin tincture, capsaicin extract, vanillyl ether nonanoate , Vanillyl alcohol alkyl ether derivative (eg, vanillyl ethyl ether, vanillyl butyl ether (LD50: 4,900 mg / kg, molecular weight: 210), vanillyl pentyl ether, vanillyl hexyl ether), isovanillyl alcohol alkyl ether, Ethylvanillyl alcohol alkyl ether, veratrial alcohol derivative, substituted benzyl alcohol derivative, substituted benzyl alcohol alkyl ether, vanillin propylene glycol acetal, ethyl vanillin propylene glycol acetal, ginger extract, ginger oil, ginger roll (LD50: 250 mg / kg, molecular weight: 294), zingerone, hesperidin, and pyrrolidone carboxylic acid, and any combination thereof.

The solvent is not particularly limited as long as it can contain a warming stimulant, and examples thereof include lipophilic solvents and hydrophilic solvents. As the solvent, the warmth stimulant can be dissolved, dispersed, etc., for example.

Examples of the lipophilic solvent include fats and oils, for example, natural oils (for example, fatty acid esters such as triglycerides, palm oil, flaxseed oil, tri (capril / capric acid) glyceryl, etc.), hydrocarbons (for example, paraffin, for example, liquid paraffin). And so on.

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

The warming stimulant of the warming agent 26 is preferably one that stimulates temperature-sensitive TRP channels. For example, TRPV1, which is one of the temperature-sensitive TRP channels, is activated by stimulation with capsaicin, acid and the like. And when the wearer's TRPV1 is activated, heat production is triggered through the sympathetic nervous system (the wearer produces heat in the body), that is, it becomes hot in itself like a portable disposable body warmer. Instead of warming the wearer, it is preferable to warm the wearer without becoming hot in itself like capsaicin or the like. The wearer can feel the coldness and warmth without low temperature burns or burns.

Further, the warming agent 26 tends to exert its effect by directly touching the wearer's skin. For example, a volatile substance such as a fragrance can exert an effect of suppressing the odor of the surroundings when it becomes a gas, but the warming agent 26 comes into direct contact with the wearer's skin after vaporization, and its main effect is Demonstrate. That is, when the warming agent 26 comes into contact with the wearer's skin via the non-woven fabric (first skin side sheet 24a) or the like, the wearer can gradually feel the effect of the warming agent 26 on the skin.

<<< Individual packaging 100 >>>
The absorbent article 1 is packaged in a packaging material (also referred to as “containment material”) 101 to form an individual package 100. FIG. 5 is a plan view of the individual package 100. The absorbent article 1 in the individual package 100 is housed inside the packaging material 101 in a state of being folded by the folded portions LB, RB, and BL along the vertical direction and the horizontal direction. Hereinafter, the individual package 100 and the absorbent article 1 packaged in the packaging material 101 are referred to as "individual package 100 in the package state" and "absorbent article 1 in the package state", and can be packaged in the packaging material 101. The absorbent article 1 in the state is also referred to as a "folded state".

Further, in FIG. 5 and the like, the left-right direction and the up-down direction of the absorbent article 1 are along the left-right direction and the up-down direction of the individual package 100, and the front-back direction of the absorbent article 1 is the thickness direction of the individual package 100. It shall be in line with. Further, in the packaging state, the packaging material 101 has a folding direction along the folding portions LC1 and LC2 (described later), an orthogonal direction orthogonal to the folding direction, and a thickness direction orthogonal to the folding direction and the orthogonal direction. There is. In the individual package 100 in the packaged state, the folding direction of the packaging material 101 is along the vertical direction of the individual package 100 and the absorbent article 1, and the orthogonal direction of the packaging material 101 is the vertical direction of the individual package 100 and the absorbent article 1. Along the left-right direction, the thickness direction of the packaging material 101 is along the thickness direction of the individual package 100 and the front-rear direction of the absorbent article 1.

The individual package 100 includes a temporary fixing unit T that temporarily fixes the absorbent article 1 and the packaging material 101 so as to be separable from each other, and a regulating unit S that restricts the movement of the absorbent article 1 to the packaging material 101 in a predetermined direction. have.

Hereinafter, a method for manufacturing the individual package 100 will be described. FIG. 6 is a diagram showing a flow of a manufacturing method of the individual package 100. The individual package 100 is manufactured by going through the absorbent article 1 and the absorbent article manufacturing step (S1) to the end joint forming step (S6) shown in FIG.

<Absorbable article manufacturing process (S1)>
First, the absorbent article manufacturing step (S1) for manufacturing the absorbent article 1 is performed. As for the above-mentioned absorbent article 1, the absorbent article 1 shown in FIGS. 1 to 4 is manufactured by a well-known method.

<Absorbable article folding process S2>
Next, an absorbent article folding step (S2) is performed to bring the absorbent article 1 manufactured in the absorbent article manufacturing step (S1) into a folded state. Specifically, the unfolded absorbent article 1 shown in FIG. 7 is changed to the folded absorbent article 1 shown in FIG. FIG. 7 is a schematic view of the absorbent article 1 in the unfolded state as viewed from the dorsal side. FIG. 9 is a diagram showing an absorbent article 1 in a folded state.

The absorbent article 1 in the folded state is formed by folding at the folding reference positions B1, B2, and B3 from the unfolded state shown in FIG. 7. The folding reference positions B1, B2, and B3 are positions that serve as reference points (fulcrums) for folding the absorbent article 1, respectively. In the absorbent article 1 (individual package 100), first, from the unfolded state shown in FIG. 7, the absorbent article 1 (individual package 100) is folded inward in the left-right direction at the folding reference positions B1 and B2, respectively. The folding reference position B1 is a reference position for folding along the vertical direction, and is provided at an arbitrary position of the one-side extending portion 10L. The folding reference position B2 is a reference position for folding along the vertical direction, and is provided at an arbitrary position on the other side extending portion 10R. The folding reference position B3 is a reference position for folding along the left-right direction, and is provided below the center (inseam side) in the vertical direction of the absorbent article 1.

From the unfolded state shown in FIG. 7, first, using a folding device (not shown), the portion of the one-side extending portion 10L outside the folding reference position B1 in the left-right direction is folded toward the dorsal side. The state shown in FIG. 8A is obtained, and then, of the other side extending portion 10R, the portion outside the folding reference position B2 in the left-right direction is folded toward the dorsal side, so that the state shown in FIG. 8B is obtained. FIG. 8A is a diagram showing a state in which the absorbent article 1 of FIG. 7 is folded at the folding reference position B1. FIG. 8B is a diagram showing a state in which the absorbent article 1 of FIG. 8A is folded at the folding reference position B2. As shown in FIG. 8B, by folding at the folding reference positions B1 and B2, a part of the folded part of the one-side extension portion 10L and a part of the folded part of the other-side extension portion 10R. Are stacked in the thickness direction (front-back direction). As a result, the length of the absorbent article 1 in the folded state in the left-right direction can be further shortened.

In a state where the portion of the one-side extending portion 10L and the portion of the other-side extending portion 10R are folded at the folding reference position B1 and the folding reference position B2, respectively (FIG. 8B), the absorbent article 1 is placed in the thickness direction (front-back direction). When viewed from the upper side (for example, the dorsal side), the one-sided folding portion LB in the left-right direction is referred to as "one-side folding portion LB", and the othermost end in the left-right direction is referred to as "other-side folding portion RB". The one-side folding portion LB and the other-side folding portion RB are also referred to as "left-right folding portions". The one-side folding portion LB and the other-side folding portion RB are respectively along the vertical direction. Since the absorbent article 1 has a predetermined thickness, the one-side folding portion LB and the other-side folding portion RB in the folded state are located outside the folding reference position B1 and the folding reference position B2 in the left-right direction, respectively. .. In the unfolded state, the one-side folding portion LB overlaps the folding reference position B1 in the front-rear direction, and the other-side folding portion RB overlaps the folding reference position B2 in the front-rear direction. Further, in the present embodiment, it has been described that the "left-right folding portions LB and RB along the vertical direction" are parallel to the vertical direction of the absorbent article 1, but the present invention is not limited to this. The left and right folded portions LB and RB along the vertical direction may be tilted within a range of 45 degrees with respect to the vertical direction, respectively.

Subsequently, with respect to the absorbent article 1 in the state shown in FIG. 8B, the portion below the folding reference position B3 (inseam side) is folded toward the upper side (girth opening 1a side) in the vertical direction, so that FIG. 9 shows. It becomes the absorbent article 1 in the folded state shown. When the absorbent article 1 in the folded state in which the absorbent article 1 is folded in the vertical direction at the folding reference position B3 along the left-right direction is viewed from the upper side in the thickness direction, the lowermost end in the vertical direction is ". It is called "upper and lower folding part BL". The vertically folded portion BL is along the left-right direction. Since the absorbent article 1 has a predetermined thickness, the vertically folded portion BL in the folded state is located above the folding reference position B3 in the vertical direction (on the waist circumference opening 1a side). In the unfolded state, the vertically folded portion BL overlaps with the folding reference position B3 in the front-rear direction. Further, in the present embodiment, the "vertical folding portion BL along the left-right direction" has been described as being parallel to the left-right direction of the absorbent article 1, but the present invention is not limited to this. The vertically folded portion BL along the left-right direction may be tilted within a range of 45 degrees with respect to the left-right direction.

In the present embodiment, in the folded state, the length from the waist opening 1a (the upper end of the absorbent article 1 in the natural state) to the end of the inseam 10 m is made as short as possible (from the waist opening 1a to the end of the crotch 10 m). By setting the length of the absorbent article 1 to 0 or approaching 0), the length of the absorbent article 1 in the folded state in the vertical direction is shortened. Further, as shown in FIG. 3, it is preferable that the folding reference position B3 is provided so as to be orthogonal to the vertical direction of the absorber 22 in the unfolded state. Further, the folding reference position B3 may be provided so as to intersect the squeezing portion 40 provided in the absorbent main body 20. The absorber 22 is a member having high rigidity in the absorbent article 1. Similarly, the squeezed portion 40 is a portion of the absorbent article 1 having a higher rigidity. By folding the absorbent article 1 at a portion intersecting with the highly rigid pressing portion 40, it becomes easy to give a so-called folding habit to the absorbent body 22, and it becomes easy to maintain the folded state of the absorbent article 1, so that the individual package 100 Is easy to maintain in a compact shape. In the folded state of the absorbent article 1, one side surface in the thickness direction is the waist circumference opening side region 1as having the waist circumference opening 1a, and the other side surface is the inseam side region 1ms having the inseam lower portion 10 m. (See FIG. 13A).

<Adhesive application step (S3)>
After the absorbent article folding step (S2), the absorbent article 1 in the folded state is wrapped with the packaging material 101. An adhesive application step (S3) is performed in which the rectangular packaging material 101 having a size larger than that of the absorbent article 1 in the folded state is horizontally spread and the adhesive G is applied to an arbitrary position. The adhesive G of the present embodiment is along the folding direction along the folding portions LC1 and LC2 formed in the step after the package 101, and is continuous from one end to the other end in the folding direction (FIG. 10). ). The adhesive G is an adhesive for forming a temporary fixing portion T that temporarily fixes the absorbent article 1 and the packaging material 101 so as to be separable from each other.

It is preferable that the adhesive G is provided between the folding reference position L1 and the folding reference position L2 in the left-right direction in the packaging material 101. As a result, the packaged material 101 in a packaged state formed through the steps described later includes a one-side folded portion LC1 and a other-side folded portion LC2, and has an end joint portion 103 (one side end portion) at each end portion in the vertical direction. When the joint portion 103a and the other side end joint portion 103b) are provided (FIG. 5), the temporary fixing portion T of the individual package 100 is one end of the packaging material 101 in the left-right direction (one-side folding portion LC1). The continuous surface from the other end (the other side folded portion LC2) and the absorbent article 1 are temporarily fixed. That is, of each surface of the individual package 100 shown in FIG. 5, one surface in the thickness direction is the surface on which the first folded portion 101L and the second folded portion 101R are overlapped, and the other side. Since the surface is a surface that does not have the folded portions 101L and 101R, it is preferable to provide the temporary fixing portion T on the other surface that does not have the folded portions 101L and 101R. As a result, even after the folding step (S5) described later, the surface provided with the adhesive G (temporary fixing portion T) is unlikely to be a portion to be folded back. It is possible to reduce the possibility that the absorbent article 1 is displaced with respect to the packaging material 101 temporarily fixed by the fixing portion T).

<Absorbable article placing process (S4)>
After the adhesive application step (S3), an absorbent article placing step (S4) is performed in which the absorbent article 1 in a folded state is placed on the adhesive G applied to the packaging material 101. FIG. 10 is a diagram illustrating a state after the absorbent article placing step. The adhesive G located between the absorbent article 1 and the packaging material 101 forms a temporary fixing portion T in which the absorbent article 1 is temporarily fixed to the packaging material 101.

In the absorbent article placing step, when the absorbent article 1 is placed on the packaging material 101 coated with the adhesive G, the absorbent article 1 is placed in the thickness direction with respect to the absorbent article 1 and the packaging material 101. It is preferable to apply a predetermined pressure from the above. As a result, the temporary fixing portion T of the absorbent article 1 and the packaging material 101 by the adhesive G provided between the absorbent article 1 and the packaging material 101 becomes stronger. Although no special means is given for the pressure on the absorbent article 1 and the packaging material 101, it is sufficient to bond the absorbent article 1 and the packaging material 101, and the pressure is due to the weight of the absorbent article 1. May be good.

In the absorbent article 1 in the folded state after the absorbent article placing step, the inseam side region 1 ms is on the side where the inseam side region 1 ms is in contact with the adhesive G (lower side), and the waist circumference opening side region 1 as is on the side where the adhesive G is not in contact (lower side). (Upper side) (see FIG. 13A). The first folding reference position L1 and the second folding reference position L2 shown in FIG. 10 are reference positions for folding the packaging material 101 in the folding process. At this time, the first folding reference position L1 and the second folding reference position L2 are set so as to be along the vertical direction of the absorbent article 1.

The packaging material 101 uses a material that does not easily allow volatile substances such as the heat sensitizer 26 to permeate (so-called high gas barrier property), so that the heat sensitizer 26 included in the absorbent article 1 can be placed outside the individual packaging body 100. The risk of outflow can be reduced. As the packaging material 101 that does not easily allow volatile substances to permeate, it is preferable to use a sheet member having an oxygen permeability in the thickness direction of 200 cc / m ² / day / atm or less at 23 ° C.

As the packaging material 101, for example, a sheet member made of EVOH resin (ethylene-vinyl alcohol copolymer resin), PET (polyester), aluminum, polyvinyl alcohol, nylon, or the like can be used. The packaging material 101 of the present embodiment is a sheet of a multi-layer film material of PE / admer / EVOH / admer / PE containing an EVOH resin (ethylene-vinyl alcohol copolymer resin). The oxygen permeability of the packaging material 101 can be measured by a well-known method such as a coulometric method (MOCON method) under the conditions of 23 ° C. and 0% RH.

<Folding process (S5)>
After the absorbent article placing step (S4), a folding step (S5) for folding the packaging material 101 is performed. Absorbent article 1 in which the packaging material 101 is folded at the reference position L1, the first folded portion 101L on one side in the left-right direction of the packaging material 101 is directed toward the other side in the left-right direction, and the first folded portion 101L is folded. By folding it so as to cover the waist circumference opening side region 1as, the state shown in FIG. 11 is obtained. FIG. 11 is a diagram showing a state in which one side of the absorbent article 1 and the packaging material 101 in the left-right direction is folded back, and the folded first folded-back portion 101L is shown by a diagonally downward diagonally lower left portion. As shown in FIG. 11, by setting the folding reference position L1 as one end in the left-right direction of the absorbent article 1, there is a gap between the absorbent article 1 and the packaging material 101 on one side in the left-right direction. It can be in a state where there is almost no (small gap). Further, in a state where the first folded portion 101L is folded back at the folding reference position L1, the individual package 100 (individual package 100 in the middle of packaging) is placed on the upper side (for example, the back) in the thickness direction (front-back direction of the absorbent article 1). The one-sided end in the left-right direction when viewed from the side) is referred to as "one-side folding portion LC1".

With one side of the absorbent article 1 and the packaging material 101 folded back in the left-right direction, an adhesive 101h such as a hot melt adhesive is applied to the other end of the outer surface of the first folded portion 101L in the left-right direction. do. The adhesive 101h is an adhesive portion for joining the first folded portion 101L and the second folded portion 101R to form the inner joint portion 102. The adhesive 101h prevents foreign matter from entering the inside of the individual packaging body 100, and reduces the risk of the warming agent (volatile substance) 26 provided in the absorbent article 1 flowing out from the individual packaging body 100. Therefore, it is preferable that the packaging material 101 is continuously applied from the upper end to the lower end in the vertical direction of the absorbent article 1. Since the adhesive 101h only needs to be able to bond the outer surface of the first folded portion 101L and the inner surface of the second folded portion 101R, the adhesive 101h is not provided on the outer surface of the first folded portion 101L. 2 The adhesive 101h may be provided on the inner surface of the folded-back portion 101R.

Subsequently, at the folding reference position L2 of the packaging material 101, the second folded portion 101R on the other side in the left-right direction of the packaging material 101 is moved toward one side in the left-right direction, and the first folded portion 101L and the second folded portion 101R are formed. By folding the folded absorbent article 1 so as to cover the waist circumference opening side region 1as, the state shown in FIG. 12 is obtained. FIG. 12 is a diagram showing a state in which the other side of the absorbent article 1 and the packaging material 101 in the left-right direction is folded back. In FIG. 12, the folded second folded portion 101R is shown by a diagonally downward diagonally downward portion. By setting the folding reference position L2 as the other end of the absorbent article 1 in the left-right direction, there is almost no gap (small gap) between the absorbent article 1 and the packaging material 101 on the other side in the left-right direction. Can be. Further, in a state where the second folded portion 101R is folded back at the folding reference position L2, the individual package 100 (individual package 100 in the middle of packaging) is placed on the upper side (for example, the back) in the thickness direction (front-back direction of the absorbent article 1). The end on the farthest side in the left-right direction when viewed from the side) is referred to as "the other side folding portion LC2".

With the other side of the absorbent article 1 and the packaging material 101 folded back in the left-right direction, at the substantially central portion in the left-right direction, the other end portion of the first folded portion 101L in the left-right direction and the left and right sides of the second folded portion 101R. The end portion on one side in the direction is overlapped and joined by the adhesive 101h provided on the outer surface of the first folded portion 101L to form the inner joining portion 102. That is, the inner joint portion 102 is a joint portion made of the adhesive 101h. It is preferable that the inner joint portion 102 is along the one-side folding portion LC1 and the other-side folding portion LC2 in the vertical direction, and is continuous from one side end to the other side end in the vertical direction. Further, the inner joint portion 102 is provided inside the one-side folding portion LC1 and inside the other-side folding portion LC2 in the left-right direction (orthogonal direction). The inner joint portion 102 of the present embodiment is provided between the one-side folding portion LC1 and the other-side folding portion LC2 in the left-right direction, and is provided at a substantially central portion in the orthogonal direction in the individual package 100. By the folding step (S5), the packaging material 101 is formed with a surface on which the inner joint portion 102 is not provided and a surface on which the inner joint portion 102 is provided in the thickness direction.

In the state where the other side folded portion 101R shown in FIG. 12 is folded, the first folded portion 101L and the second folded portion 101R are overlapped with each other when the individual package 100 is viewed in the thickness direction, and the adhesive 101h is provided. It is preferable to apply pressure in the thickness direction to the region. By applying pressure in the thickness direction, the bonding between the packaging materials 101 with the adhesive 101h (inner bonding portion 102) can be more reliably fixed. Similarly, when viewed in the thickness direction, it is preferable to apply pressure in the thickness direction to the portion of the individual package 100 in the middle of packaging that overlaps with the coating region of the adhesive G. As a result, by fixing the packaging materials 101 at both ends of the individual packaging body 100 in the vertical direction with the adhesive G, the regulating unit S that regulates the vertical movement of the absorbent article 1 with respect to the packaging material 101 is provided. Can be formed. The restricting portion S joins the packaging materials 101 to each other in the same manner as the end joining portions 103a and 103b, but is different from the end joining portions 103a and 103b. Although no particular means is given for the pressure for joining the packaging materials 101 to each other, it is sufficient to bond the packaging materials 101 to each other, and the pressure may be due to the weight of the material (packaging material 101).

By performing the folding step (S5) after performing the absorbent article placing step (S4) after the adhesive application step (S3), the packaging material is restricted from moving to the packaging material 101. The first folded portion 101L is folded at the one-side folded portion LC1 of 101, and then the second folded portion 101R is folded at the other-side folded portion LC2. That is, since the folding step (S5) can be performed in the state where the absorbent article 1 is temporarily fixed to the packaging material 101 by the temporary fixing portion T, the one-side folding portion LC1 (folding reference position L1) and the other The side folding portion LC2 (folding reference position L2) can be provided at an accurate position, and the packaging material 101 can be folded at an accurate position. Therefore, it is possible to shorten the gaps between the absorbent article 1 and the one-side folded portion LC1 and the other-side folded portion LC2, and the individual package 100 can be made into a compact shape.

<End joint forming step (S6)>
After the folding step (S5), the end joint forming step (S6) is performed to form a pair of end joints 103. In the end joint forming step (S6), one end joint 103a and the other end joint 103a are formed on one end and the other end of the packaging material 101 in the vertical direction (orthogonal direction), respectively. Form 103b. The one side end joint portion 103a and the other side end portion joint portion 103b are joint portions formed by welding by applying heat and pressure. It is preferable that the one-side end joint portion 103a and the other side end portion joint portion 103b are continuous in the left-right direction (orthogonal direction) from one side end to the other side end in the left-right direction. By forming the pair of end joints 103, the absorbent article 1 is housed in the packaging material 101, and becomes an individual package 100 as shown in FIG.

Similar to the folding step (S5), the absorbent article 1 is performed by performing the end joint forming step (S6) after performing the absorbent article placing step (S4) after the adhesive application step (S3). The end joint 103 can be formed with the movement of the packaging material 101 restricted. Therefore, in the end joint forming step (S6), it is possible to reduce the risk of poor joining caused by the movement of the absorbent article 1 and the inability to form the end joint 103 at an accurate position. Further, it becomes easy to determine the position where the end joint portion 103 of the packaging material 101 is provided, and it becomes easy to provide the end joint portion 103 at an accurate position.

<Individual packaging 100 in the packaged state>
Generally, in an individual package of an absorbent article housed in a packaging material, the larger the storage space inside the packaging material, the easier it is for the absorbent article to move inside the packaging material. In particular, pants-type absorbent articles such as shorts-type napkins and tape-type absorbent articles do not have an adhesive portion on the outer surface for adhesively fixing to clothes like ordinary sanitary napkins and absorbent pads. Therefore, if the product is carried in the state of an individual package, the absorbent article may move inside the packaging material due to vibration during the carrying, and the absorbent article may collide with the packaging material. May be deformed or damaged.

On the other hand, the individual package 100 of the present embodiment has a temporary fixing portion T for temporarily fixing the absorbent article 1 and the packaging material 101 so as to be separable from each other. As shown in FIGS. 5, 13A, and 13B, the temporary fixing portion T is a portion where the absorbent article 1 and the packaging material 101 are temporarily fixed. FIG. 13A is a schematic cross-sectional view taken along the line DD in FIG. FIG. 13B is a schematic cross-sectional view taken along the line EE in FIG. Specifically, the temporary fixing portion T for which the absorbent article 1 in the packaged state and the packaging material 101 are temporarily fixed is the non-skin side surface of the absorbent article 1 (the exterior back sheet 12 of the exterior body 10 or the absorbent main body 20). The side sheet 24d) and the inner surface of the packaging material 101 are bonded with the adhesive G. The absorbent article 1 temporarily fixed to the packaging material 101 by the temporary fixing portion T can be separated from the packaging material 101 when the absorbent article 1 is used without substantially damaging the absorbent article 1. After separation, it can be used without impairing the function of the absorbent article 1. By providing the temporary fixing portion T, the movement of the absorbent article 1 can be restricted inside the packaging material 101, so that the absorbent property accommodated inside the individual package 100 due to the vibration or the impact from the outside. The risk of the article 1 being deformed or damaged can be reduced. Further, even if the absorbent article 1 is soft like the absorbent article 1, the temporary fixing portion T restricts the movement of the absorbent article 1 with respect to the packaging material 101, so that the folded state of the absorbent article 1 can be easily maintained. It becomes easy to hold the individual package 100 compactly.

Further, as described above, it is preferable that the temporary fixing portion T is an adhesive portion bonded with the adhesive G. The adhesive G used for the adhesive portion of the temporary fixing portion T is preferably one capable of adhering the absorbent article 1 in the temporarily fixed state and the packaging material 101 with a separable strength. As the adhesive G of the temporary fixing portion T, for example, a hot melt adhesive of an SBS copolymer can be used. The SBS copolymer hot melt adhesive has a tack force (fixing strength) of 1 ounce (about 28.35 g) / 25 mm or less. The "fixing strength (tack force)" of the temporary fixing portion T is measured based on the loop tack method based on JIS Z 0237. Specifically, the joint portion coated with the adhesive is cut to a width of 25 mm to prepare a sample, and the sample is set in a tensile tester so as to form a loop. Apply a T-shaped stainless steel plate from below the sample and adhere it to the joint of the sample. The stainless steel plate is moved downward at a speed of 300 mm / min, and the tensile force when the stainless steel plate and the sample are peeled off is measured and used as the fixing strength.

It is preferable that the packaging material 101 is provided with the adhesive G of the temporary fixing portion T in a state where the absorbent article 1 is taken out from the packaging material 101 of the individual packaging body 100 in the packaged state shown in FIG. That is, when the temporary fixing of the packaging material 101 of the individual packaging body 100 and the absorbent article 1 is separated and the absorbent article 1 and the absorbent article 1 are taken out from the packaging material 101, the adhesive G of the temporary fixing portion T becomes the packaging material 101. It is preferable to remain in. At this time, it is more preferable that the adhesive G does not adhere to the absorbent article 1 taken out. By providing the packaging material 101 with the adhesive G of the temporary fixing portion T in a state where the absorbent article 1 is taken out from the packaging material 101, the risk of the adhesive G adhering to the taken out absorbent article 1 is reduced. The adhesive G can reduce the risk of damaging the clothes and underwear that come into contact with the absorbent article 1 when worn.

In a state where the absorbent article 1 is taken out from the packaging material 101 of the individual packaging material 100, the configuration in which the packaging material 101 includes the adhesive G of the temporary fixing portion T is, for example, an SBS copolymer in a state of being melted in the packaging material 101. It can be realized by applying the hot melt adhesive (adhesive G) of the above and adhering the absorbent article 1 to the adhesive G on the packaging material 101 until the temperature reaches room temperature. In the production line, the adhesive G when applied to the packaging material 101 is in a molten state, but the viscosity of the adhesive G increases before the absorbent article 1 is adhered after being applied to the packaging material 101. It is possible to reduce the possibility that the adhesive G permeates into the exterior body 10 of the absorbent article 1 and the inside of the absorbent main body 20. When the absorbent article 1 temporarily fixed by the temporary fixing portion T with the adhesive G and the packaging material 101 are separated, the adhesive G separates from the absorbent article 1 together with the packaging material 101, and the absorbent article It can be made so that it hardly remains in 1.

In the state where the absorbent article 1 is taken out from the packaging material 101 of the individual package 100 in the packaged state, when the packaging material 101 is provided with the adhesive G of the temporary fixing portion T, the absorbent article 1 is completely an adhesive G. The absorbent article 1 may be provided with some adhesive G. However, it is more preferable that the amount of the adhesive G contained in the absorbent article 1 is smaller than the amount of the adhesive G contained in the packaging material 101.

Further, as shown in FIG. 13A, in the individually packaged body 100 in the packaged state, it is preferable to temporarily fix the inseam side region 1 ms on the inseam side and the packaging material 101 in the absorbent article 1 in the folded state. That is, the temporary fixing portion T temporarily fixes the crotch portion of the absorbent article 1 and the packaging material 101 with the adhesive G. Usually, the crotch portion of the absorbent article 1 is provided with a highly rigid absorber 22 and is easily maintained in a flat state. Therefore, by temporarily fixing the inseam side region 1 ms on the inseam side of the vertically folded portion BL and the packaging material 101, the absorbent article 1 and the packaging material 101 can be easily grounded and can be temporarily fixed more firmly. ..

As described above, the absorbent article 1 includes an exterior body 10 and an absorbent body 20 joined to each other. In the state where the inseam side region 1 ms and the packaging material 101 are temporarily fixed, the fixing strength between the absorbent article 1 and the packaging material 101 in the temporary fixing portion T is higher than the bonding strength between the exterior body 10 and the absorbent body 20. Low is preferred. When the absorbent article 1 is taken out from the individual package 100, the packaging material 101 and the absorbent article 1 can be easily separated while reducing the risk of peeling off the joint between the exterior body 10 and the absorbent main body 20. The risk of damage to the absorbent article 1 can be reduced. The absorbent article 1 of the present embodiment has a structure in which the absorbent main body 20 provided with the absorbent body 22 and the outer body 10 are joined, but the present invention is not limited to this. For example, it may be an absorbent article having a structure in which the absorbent body 22 is directly bonded to the outer body 10 without the absorbent main body 20. In this case, it is preferable that the fixing strength between the absorbent article 1 (inseam side region 1 ms) and the packaging material 101 in the temporary fixing portion T is lower than the bonding strength between the exterior body 10 and the absorbent body 22.

The "fixing strength" between the absorbent article 1 and the packaging material 101 in the temporary fixing portion T and the "bonding strength" between the exterior body 10 and the absorbent main body 20 are the fixing of the absorbent article 1 and the packaging material 101, respectively. It refers to the magnitude of the force per unit area for separating the outer body 10 and the magnitude of the force per unit area for separating (peeling) the joint between the exterior body 10 and the absorbent main body 20. That is, the fixing strength or the bonding strength and the separation strength (peeling strength) are the same.

The fixing strength and the joint strength can be measured by a well-known method. Specifically, the above-mentioned fixed strength measuring method may be used, or the following method may be used for measurement.
First, samples 1 and 2 having the same area are cut out from the individual package 100 and the absorbent article 1 to be measured. The sample 1 is a portion of the individual package 100 provided with a temporary fixing portion T to which the absorbent article 1 and the packaging material 101 are temporarily fixed, and the sample 2 is an exterior body of the absorbent article 1. It is a portion where 10 and the absorbent main body 20 are joined. Next, sample 1 or sample 2 is set on the upper and lower chucks of a tensile tester (for example, Instron series 5564 manufactured by Instron Co., Ltd.). After that, the upper and lower chucks are separated from each other at a predetermined tensile speed (for example, 300 mm / min), and the samples 1 and 2 are pulled. The maximum load (N) until the distance between the chucks is increased is acquired. For each of Samples 1 and 2, n (for example, 10) measurement results are acquired, and the average value of n maximum loads (N) is calculated. Then, the average value (N) of the sample 1 is defined as the fixing strength between the absorbent article 1 and the packaging material 101 in the temporary fixing portion T, and the average value (N) of the sample 2 is the bonding between the exterior body 10 and the absorbent main body 20. Both values can be compared with each other as the intensity. The fixing strength and the bonding strength in the following description can also be compared by the same measuring method.

As described above, in order to bring the individual package 100 in the packaged state into a sealed state, the end joints 103a and 103b along the left-right direction (orthogonal direction) in which the packaging materials 101 are joined are vertically (folded). It is held at both ends of the direction). It is preferable that the fixing strength between the absorbent article 1 and the packaging material 101 at the temporary fixing portion T is lower than the bonding strength between the packaging materials 101 at the end joining portions 103a and 103b. Since the fixing strength of the temporary fixing portion T is lower than the joining strength of the end joining portions 103a and 103b, the absorbent article 1 can be separated from the packaging material 101 of the individual packaging body 100 with a small force. On the other hand, since the joint strength of the end joint portions 103a and 103b is stronger than the fixing strength of the temporary fixing portion T, the bag-like shape of the packaging material 101 is maintained even after the absorbent article 1 is removed from the packaging material 101. Since it is easy to carry out, the absorbent article 1 after use can be stored in the packaging material 101.

Similarly, it is preferable that the fixing strength of the absorbent article 1 and the packaging material 101 in the temporary fixing portion T by the adhesive G is weaker than the adhesive strength between the packaging materials 101 in the inner joint portion 102. Since the temporary fixing between the absorbent article 1 and the packaging material 101 can be easily separated while preventing the inner joint portion 102 from peeling off and making it easy to maintain the packaging material 101 in a bag shape, the wearer or the like can absorb the material. The used absorbent article 1 can be accommodated in the bag-shaped packaging material 101 while reducing the risk of the property article 1 being damaged.

Further, the individual package 100 has a regulating unit S that restricts the movement of the absorbent article 1 with respect to the packaging material 101 in a predetermined direction. As shown in FIG. 5 and the like, the individual package 100 of the present embodiment has a packaging material at one end and the other end in the folding direction of the packaging material 101 (vertical direction of the absorbent article 1), respectively. It is provided with end joints 103a and 103b to which 101s are joined, and has a restricting portion S between one side end joint 103a and the absorbent article 1 on one side in the folding direction, and the other in the folding direction. On the side, there is a regulating portion S between the other side end joint portion 103b and the absorbent article 1.

By providing the regulating portion S, the movable area of the absorbent article 1 inside the packaging material 101 can be narrowed. Therefore, by providing the restricting portion S outside the absorbent article 1 in the predetermined direction of the packaging material 101, the movement of the packaging material 101 in the predetermined direction (folding direction) can be restricted, and the absorbent article 1 in the packaged state can be used. It is possible to reduce the risk of bending or breakage caused by moving inside the packaging material 101. Further, since the regulating portion S reduces the movable area of the absorbent article 1 inside the packaging material 101, it becomes easy to maintain the folded state 1 of the absorbent article 1, and it becomes easy to maintain the individual package 100 in a compact shape. Become.

The regulating portion S is preferably a portion where the packaging materials 101 are bonded to each other, and more preferably a regulating portion S bonded by an adhesive such as a hot melt adhesive. Further, the restricting portion S is preferably provided between the one-side end joint portion 103a and the absorbent article 1 in the folding direction, and is provided between the other side end joint portion 103b and the absorbent article 1. Is preferable. FIG. 13C is a schematic cross-sectional view taken along the line FF in FIG.

In the individual package 100, the regulation portion S is formed by joining the packaging materials 101 to each other with the adhesive G applied to the packaging material 101 in the above-mentioned adhesive application step S3 (see FIG. 10). The restricting portion S in which the packaging materials 101 are joined to each other is placed between the one-side end joint 103a and the absorbent article 1 in the folding direction, and between the other end joint 103b and the absorbent article 1. It is provided. That is, the absorbent article 1 is arranged between the regulation portion S on one side and the regulation portion S on the other side in the folding direction. Further, the regulating portion S on one side and the regulating portion S on the other side in the folding direction are provided at overlapping positions in the left-right direction.

Since the absorbent article 1 housed in the packaging material 101 regulates the movable region in the predetermined direction inside the packaging material 101 by the regulating unit S, the movement in the folding direction with respect to the packaging material 101 is restricted. Can be done. In the individual package 100, the regulation unit S is provided on one side and the other side of the absorbent article 1 in the folding direction, but the present invention is not limited to this. The regulation unit S may be provided in at least one of the directions in which the movement of the absorbent article 1 is restricted with respect to the packaging material 101.

Further, the individual package 100 shown in FIG. 5 and the like has a temporary fixing portion T and a regulating portion S. Therefore, the temporary fixing portion T temporarily fixing the absorbent article 1 to the packaging body 101 is provided with a restricting portion S by joining the packaging materials 101 to each other while restricting the movement of the absorbent article 1 with respect to the packaging material 101. Since the movement of the absorbent article 1 with respect to the packaging material 101 in the folding direction (predetermined direction) can be restricted, the movement of the absorbent article 1 housed in the individual package 100 in the packaged state can be further restricted, and the absorbent article 1 can be restricted. The damage and bending of the individual package 100 are further reduced, and the individual package 100 can be easily held in a compact shape.

As shown in FIG. 5 and the like, in the individual package 100, the temporary fixing portion T and the regulating portion S are provided by a continuous adhesive portion (adhesive G). Therefore, since the adhesive G continuous in the folding direction increases the rigidity of the individual packaging body 100 in the folding direction, it becomes easy to reduce the deformation of the individual packaging body 100.

Further, even when the absorbent article 1 housed in the individual package 100 is provided with a volatile substance such as the warming agent 26, the individual package 100 is provided with the temporary fixing portion T or the regulation portion S, so that the packaging material is provided. Since the movement of the absorbent article 1 with respect to the 101 can be restricted, the movement of the absorbent article 1 inside the packaging material 101 promotes the volatility of the warming agent 26 due to irritation or air circulation, or a feeling of warmth. The risk of the agent 26 flowing out can be reduced.

=== Other embodiments ===
The above embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. It goes without saying that the present invention can be modified or improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.

In the above-described embodiment, the packaging material 101 is an individual package 100 including a one-side folding portion LC1 and a other-side folding portion LC2, but the present invention is not limited to this. The individual packaging body 100 in which the packaging material 101 has only one folding portion, the individual packaging body 100 in which the packaging material 101 has three or more folding portions, and the packaging material 101 do not have to have the folding portion. Further, the individual package 100 does not necessarily have to have the inner joint portion 102, and the inner joint portion 102 does not necessarily have to be the central portion in the orthogonal direction. For example, the inner joint portion 102 is orthogonal to each other. It may be provided at the other end in the direction.

Further, in the above-described embodiment, the absorbent article 1 in the folded state is in a state of being folded by the left and right folded portions LB and RB and the vertically folded portion RB, but the present invention is not limited to this. The absorbent article 1 in the folded state may be folded by the left and right folding portions LB and RB and not folded by the vertical folding portion RB, and may be folded by the vertical folding portion RB and folded by the left and right folding portions LB and RB. It may be in a non-existent state. Further, only one of the left-right folding portion LB and the left-right folding portion RB may be folded.

In the above-described embodiment, the packaging material 101 is provided with the adhesive G of the temporary fixing portion T in a state where the absorbent article 1 is taken out from the packaging material 101 of the individual packaging body 100 in the packaged state. In the state where the absorbent article 1 is taken out from the above, the absorbent article 1 may be provided with the adhesive G of the temporary fixing portion T. That is, when the temporary fixing of the packaging material 101 of the individual packaging body 100 and the absorbent article 1 is separated and the absorbent article 1 and the absorbent article 1 are taken out from the packaging material 101, the adhesive G of the temporary fixing portion T is the absorbent article. It may be the one provided (adhered) to 1. With the absorbent article 1 taken out from the packaging material 101, the absorbent article 1 is provided with the adhesive G, so that the adhesive force of the adhesive G can be used to attach the wearer's clothes and underwear to the absorbent article 1 when worn. It becomes easy to temporarily fix it, and it is possible to reduce the deviation of the absorbent article 1 during wearing. When the absorbent article 1 is taken out from the packaging material 101 of the individual package 100 in the packaged state and the absorbent article 1 is provided with the adhesive G of the temporary fixing portion T, the packaging material 101 is completely an adhesive G. The packaging material 101 may be provided with some adhesive G. However, it is more preferable that the amount of the adhesive G contained in the packaging material 101 is smaller than the amount of the adhesive G contained in the absorbent article 1.

Further, in the above-described embodiment, in the individually packaged body 100 in the packaged state, the absorbent article 1 in the folded state is accommodated in a state where the inseam side region 1 ms and the packaging material 101 are temporarily fixed (FIG. 13A and the like). ), But it is not limited to this. For example, in the individually packaged body 100 in the packaged state, the absorbent article 1 in the folded state may be temporarily fixed to the waist circumference opening side region 1as on the waist circumference opening 1a side from the vertically folded portion BL and the packaging material 101. That is, the temporary fixing portion T may be a portion in which the waist circumference portions 10f and 10b of the absorbent article 1 and the packaging material 101 are temporarily fixed with the adhesive G. Since the waist circumference portions 10f and 10b are provided with the waist circumference elastic members 13 and 14 that expand and contract in the left-right direction, wrinkles are formed on the waist circumference portions 10f and 10b due to the contraction of the waist circumference elastic members 13 and 14, and the surface thereof has an uneven shape. Will be. Therefore, since the ground contact area of the waist circumference portions 10f and 10b installed in the adhesive G in the temporary fixing portion T can be provided, there is a possibility that the absorbent article 1 and the packaging material 101 are excessively fixed by the temporary fixing portion T. This can be reduced to facilitate the separation of the absorbent article 1 from the packaging material 101.

Further, with respect to the waist circumference portions 10f and 10b of the absorbent article 1 provided with the exterior top sheet 11 and the exterior back sheet 12 joined in a state where the waist circumference opening side region 1as and the packaging material 101 are temporarily fixed, the exterior top sheet is provided. It is preferable that the fixing strength between the absorbent article 1 and the packaging material 101 in the temporary fixing portion T is lower than the bonding strength between the 11 and the exterior back sheet 12. This makes it easier to separate the packaging material 101 and the absorbent article 1 while reducing the risk of peeling the exterior top sheet 11 and the exterior back sheet 12 when the absorbent article 1 is taken out from the individual package 100. Therefore, the risk of damage to the absorbent article 1 can be reduced.

Further, in a state where the waist circumference opening side region 1as and the packaging material 101 are temporarily fixed, the temporary fixing portion T is a portion of the absorbent article 1 in which the side end joint 10e and the packaging material 101 are temporarily fixed. preferable. The side end joint 10e is a portion having high rigidity because it is a portion where the side ends of the ventral waist circumference portion 10f and the dorsal waist circumference portion 10b are joined to each other. By temporarily joining the side end joint 10e having high rigidity and the packaging material 101, the fixing strength can be further strengthened.

In the above-described embodiment, the individual package 100 includes a temporary fixing portion T and a regulating portion S, but the present invention is not limited to this. As another embodiment, the individual package 110 having the temporary fixing portion T and not having the regulating portion S as shown in FIG. 14A, or the individual packaging body 110 having the temporary fixing portion T and not having the regulating portion S as shown in FIG. 14B. It may be an individual package 120. 14A is a plan view of the individual package body 110 of another embodiment, and FIG. 14B is a plan view of the individual package body 120 of another embodiment.

Further, in the individual package 100, the temporary fixing portion T is provided from one end to the lower end in the vertical direction (predetermined direction) of the absorbent article 1, but the present invention is not limited to this. The temporary fixing portion T can be provided at an arbitrary position, an arbitrary size, and an arbitrary shape as long as it is a portion where the absorbent article 1 and the packaging material 101 come into contact with each other. For example, as shown in FIG. 14A, the temporary fixing portion T may be provided in a part in the vertical direction.

As shown in FIG. 14A, in the packaged state, the individual package 110 has one side end joint 103a and the other side end at one end and the other end in the vertical direction of the absorbent article 1, respectively. When the joint strength of the one-side end joint 103a is lower than the joint strength of the other end joint 103b, the temporary fixing portion T is vertically attached to the individual package 100 in the vertical direction. It may be provided on one side from the center of the above. The one-side end joint 103a, which has a lower joint strength than the other-side end joint 103b, can be opened (peeled) with a force smaller than that of the other end joint 103b, and is therefore a suitable portion for opening. In this case, when the joint portion of the one-side end joint portion 103a is peeled off, the individual package 110 is opened, and the absorbent article 1 is taken out, a temporary fixing portion T is provided on one side in the vertical direction. By doing so, the temporary fixing of the temporary fixing portion T can be separated at a position close to the portion where the package is opened and taken out. Therefore, in the vertical direction, the temporary fixing portion T is placed on the other side of the center of the individual package 100 in the vertical direction. The absorbent article 1 can be separated from the packaging material 101 with a smaller force than when it is provided on the side, and the absorbent article 1 can be easily taken out.

As shown in FIG. 14B, the individual package 120 may have a continuous restricting portion S from one end in the orthogonal direction to the other end along the orthogonal direction. Since the individual package 120 has a restricting portion S continuous from one end in the orthogonal direction to the other end along the orthogonal direction on one side and the other side of the folding direction of the absorbent article 1, respectively. The movement of the absorbent article 1 with respect to the packaging material 101 in the folding direction can be restricted. Further, by forming the restricting portion S continuous from one end to the other end in the orthogonal direction with an adhesive obtained by joining the packaging materials 101 to each other, the rigidity of the individual packaging body 100 in the orthogonal direction is increased, and the individual packaging material 100 is individually formed. It becomes easy to reduce the deformation of the package 100.

Further, in the above-mentioned individual package 110, the absorbent article 1 in the folded state faces the absorbent article 1 in a state where the packaging material 101 sandwiches the absorbent article 1 in the thickness direction, and the absorbent article 1 is on one side. A temporary fixing portion T is provided in the inseam side region 1 ms which is (one side), but the present invention is not limited to this. With respect to the absorbent article 1 in the folded state, the packaging material 101 faces the absorbent article 1 in a state of sandwiching the absorbent article 1 in the thickness direction, and both sides (both outer sides) of the absorbent article 1, that is, the inseam side region 1 ms. And may be configured to have a temporary fixing portion T in each of the waist circumference opening side region 1as. As a result, the movement of the absorbent article 1 with respect to the packaging material 101 can be further restricted on both sides in the thickness direction of the individual packaging body 100, so that the absorbent article 1 is in contact with the packaging material 101 inside the packaging material 101. Since the risk of contact and damage can be reduced, and the shape of the absorbent article 1 in the folded state can be easily maintained, the individual package 100 can be easily held in a compact state.

In the above-described embodiment, the individual package 100 in which the absorbent article 1 is housed is formed in a direction along the vertical direction of the absorbent article 1 and the folding direction of the packaging material 101, but the present invention is not limited to this. As shown in FIGS. 15A and 15B, the individual package 130 may contain the absorbent article 1 in a state where the left-right direction of the absorbent article 1 and the folding direction of the packaging material 101 are aligned with each other. FIG. 15A is a plan view of the individual package 130 of another embodiment. FIG. 15B is a view showing a state in which the packaging material 101 is unfolded from the inner joint portion 102 of the individual packaging body 130. As shown in FIGS. 15A and 15B, it is possible to provide a temporary fixing portion T for temporarily fixing the packaging material 101 and the absorbent article regardless of the direction in which the absorbent article 1 is accommodated with respect to the packaging material 101. It is possible to provide a regulation unit S that regulates the movement of the absorbent article 1 with respect to the packaging material 101 in the folding direction, which is formed by joining the packaging materials 101 to each other. The temporary fixing portion T of the individual package 130 can restrict the movement of the absorbent article 1 inside the packaging material 101. Further, the regulation unit S of the individual package 130 can restrict the movement of the absorbent article 1 in the packaging material 101 in the folding direction.

Further, as shown in FIGS. 15A and 15B, the individually packaged body 130 in the packaged state has end joint portions 103a and 103b to which the packaging materials 101 are joined to each other and an inner joint portion 102. In the individual package 130, the end joints 103a and 103b are provided at both ends of the packaging material 101 in the folding direction (left-right direction of the absorbent article 1), and the end joints 103a and 103b are folded. It is along an orthogonal direction (vertical direction of the absorbent article 1) orthogonal to the direction. In the individual package 130, the inner joint 102 is along the folding direction of the packaging material 101.

FIG. 15B shows a state in which the inner joint portion 102 is peeled off from the individually packaged body 130 in the packaged state shown in FIG. 15A and unfolded with respect to the other side folded portion LC2 (folding reference position L2). In FIG. 15B, the first folded portion 101L in the folded state is shown by a diagonally downward diagonally downward portion. As shown in FIGS. 15A and 15B, the individual package 130 makes it possible to unfold the wrapping material 101 for the other side folded portion LC and at the same time unfold the vertically folded portion BL of the absorbent article 1. That is, the direction in which the packaging material 101 is unfolded from the inner joint portion 102 and the direction in which the vertically folded portion BL of the absorbent article 1 is unfolded are the same. In this way, by making the unfolding direction of the packaging material 101 on the second folded-back portion 101R side and the unfolding direction of the folded absorbent article 1 the same, the joint of the inner joint portion 102 is peeled off, and the packaging material 101 is peeled off. At the same time, the vertically folded portion BL of the absorbent article 1 can be expanded, and the labor for deploying the absorbent article 1 such as the wearer can be reduced.

For the individual package 130, it is preferable to provide the temporary fixing portion T (adhesive G) on the second folded portion 101R side. As a result, the joint of the inner joint portion 102 is peeled off to unfold the packaging material 101 on the side of the second folded portion 101R, and at the same time, the portion of the absorbent article 1 temporarily fixed to the packaging material 101 (in FIG. 13B). Since the waist circumference opening 1a side is expanded in the vertical direction from the vertically folded portion BL in the expanded state, it is possible to more reliably reduce the time and effort required to deploy the absorbent article 1 such as the wearer.

In the above-described embodiment, in the absorbent article 1 in the folded state, the length in the vertical direction of the waist circumference opening side region 1as on the waist circumference opening 1a side located on one side in the thickness direction and the position on the other side in the thickness direction. The length of the inseam side region 1 ms on the inseam 1 m side in the vertical direction is substantially the same, but the length is not limited to this. The length N of the waist opening side region 1as of the folded absorbent article 1 may be longer than the vertical length M of the inseam region 1 ms (N ≧ M), and the inseam of the folded absorbent article 1 The length M of the side region 1 ms may be longer than the vertical length N of the waist circumference opening side region 1 ss (M> N).

FIG. 16A is a plan view of the individual package 140 of another embodiment. FIG. 16B is a schematic cross-sectional view taken along the line JJ in FIG. 16A. As shown in FIG. 16A, in the individual package 140 of another embodiment, the absorbent article 1 folded by the left and right folding portions LB, RB and the vertical folding portion BL is housed in the packaging material 101. Further, the adhesive G is provided only on one surface of the packaging material 101 in the thickness direction. In the absorbent article 1 of the individual package 140, the vertical length N of the waist circumference opening side region 1as is longer than the vertical length M of the inseam side region 1ms in a state of being folded by the vertical folding portion BL ( N> M). Further, in the individual package 140, in the thickness direction, an inseam side region 1 ms is provided on the adhesive G side of the temporary fixing portion T, and the inseam side region 1 ms is temporarily fixed to the packaging material 101, and the packaging material 101 is adhered. The agent G, the inseam side region 1 ms, and the waist circumference opening side region 1 as are arranged in this order. That is, the inseam side region 1 ms has a larger temporary fixing area with the packaging material 101 than the waist circumference opening side region 1 as. Since the inseam side region 1 ms is a portion provided with the absorber 22, it is a portion having higher rigidity than the waist circumference portions 10b and 10f and easily maintaining a flat state. Therefore, by providing the inseam side region 1 ms on the side of the adhesive G in the thickness direction, the temporary fixing between the inseam side region 1 ms and the packaging material 101 can be further strengthened. Further, as shown in FIG. 16B, since the vertical length N of the waist circumference opening side region 1as is longer than the vertical length M of the inseam side region 1 ms (N> M), on one side in the vertical direction, The portion of the waist circumference opening side region 1as longer than the inseam side region 1 ms comes into contact with the adhesive G and can be temporarily joined to the packaging material 101. Therefore, not only the inseam side region 1 ms of the absorbent article 1 folded by the vertically folded portion BL but also the waist circumference opening side region 1as can be temporarily joined to the packaging material 101, so that the packaging material 101 can be more absorbent. The article 1 can be temporarily fixed more firmly. Further, since it becomes easy to maintain the folded state of the absorbent article 1, it becomes easy to maintain the individual package 140 in a compact shape.

In the individual package 140, the packaging material 101, the adhesive G, the inseam side region 1 ms, and the waist circumference opening side region 1 as are arranged in this order in the thickness direction, but the present invention is not limited to this. When the length N of the waist opening side region 1as of the absorbent article 1 in the folded state is longer than the vertical length M of the inseam side region 1 ms, the packaging material 101, the adhesive G, and the waist circumference opening side are used in the thickness direction. The region 1as and the inseam side region 1ms may be arranged in this order, and the waist circumference opening side region 1as may be temporarily fixed to the packaging material 101. Since the waist circumference portions 10f and 10b have the waist circumference elastic members 13 and 14, they have a plurality of folds (wrinkles) on the surface. Therefore, the contact area of the waist circumference portions 10f and 10b with the adhesive G in the temporary fixing portion T can be reduced, and the force when the wearer or the like separates the absorbent article 1 from the packaging material 101 can be reduced. can.

When the individual package 140 is folded at the vertically folded portion BL, the vertical length N of the waist circumference opening side region 1as is longer than the vertical length M of the inseam side region 1ms (N> M). Although the article 1 is provided, it may be an absorbent article 1 in a folded state in which the vertical length M of the inseam side region 1 ms is longer than the vertical length N of the waist circumference opening side region 1 as (M>. N).

When the vertical length M of the inseam side area 1 ms is longer than the vertical length N of the waist circumference opening side area 1 as (M> N), the packaging material 101, the adhesive G, and the inseam side in the thickness direction. When the region 1 ms and the waist circumference opening side region 1 as are arranged in this order, and the inseam side region 1 ms is arranged so that the temporary fixing area with the packaging material 101 is wider than the waist circumference opening side region 1 as, the rigidity is high and the flat state is obtained. Since the crotch lower part 1 m and the packaging material 101 can be temporarily fixed in a wider range, the temporary fixing portion can be more firmly fixed.

When the vertical length M of the inseam side region 1 ms is longer than the vertical length N of the waist circumference opening side region 1 as (M> N), the packaging material 101, the adhesive G, and the waist circumference opening in the thickness direction. When the side area 1as and the inseam side area 1ms are arranged in this order and the waist circumference opening side area 1ms is arranged so that the temporary fixing area with the packaging material 101 is wider than the inseam side area 1as, the inseam side area 1ms. While temporarily fixing the packaging material 101, the portion of the inseam side region 1ms longer than the waist circumference opening side region 1as can be in contact with the adhesive G and temporarily joined to the packaging material 101 on one side in the vertical direction. .. As a result, the absorbent article 1 and the packaging material 101 can be more firmly fixed, the folded state of the absorbent article 1 can be easily maintained, and the individual package can be made into a more compact shape.

In the above-described embodiment, the temporary fixing portion T and the regulating portion S are each formed of the adhesive G, but the present invention is not limited to this. The temporary fixing portion T may be a separable temporary fixing means including a hook-and-loop fastener and an engaging portion that can engage with the hook-and-loop fastener. The individual packaging body is provided with a structure in which the packaging material has an engaging portion that can be engaged with the hook-and-loop fastener, or is housed in a packaging material made of a material (spunbonded non-woven fabric, etc.) that can be engaged with the hook-and-loop fastener. May be good. Further, the regulation portion S may be formed by a welding portion for welding and joining the packaging materials from the outer surface of the packaging material of the individual package in the packaged state.

Further, in the above embodiment, the warming agent 26 is used as an example of the volatile substance, but the warming agent 26 is not limited to the warming agent 26, and for example, a volatile substance such as a cooling agent or a fragrance may be used. The fragrance may be used in place of the warming agent 26, or may be used together with the warming agent 26 or the cooling sensation agent.

When a green herbal-like fragrance (green herbal-like fragrance) is used as the fragrance, it does not cause any physical irritation to the body and does not cause physical irritation to the body, and it does not depend on oral administration. It can be relaxed safely and easily. In addition to this, a feeling of comfort can be obtained.

When a cooling sensation agent is used, it is possible to reduce the discomfort caused by the wearer's stuffiness and stickiness. Examples of cooling sensitizers include menthol (eg, l-menthol) and derivatives thereof (eg, menthol lactate), methyl salicylate, camphor, essential oils derived from plants (eg, mint, eucalyptus) and the like. As for the cooling sensation agent, the one that stimulates the temperature-sensitive TRP channel is preferable as in the case of the warming agent 26.

As the fragrance, the same fragrances that have been conventionally used in the art can be used. When a green herbal-like fragrance (green herbal-like fragrance) is used as a fragrance, it is safe and convenient without causing physical irritation to the body and without oral administration.
