As shown in FIG. 1, the absorbent article 1 has "vertical direction", "horizontal direction", and "front-back direction" orthogonal to each other in the deployed state. The "unfolded state" refers to the absorbent article 1 in a natural state in which all the folds of the absorbent article 1 are unfolded. The "natural state" is a state when the diaper 1 is left for a predetermined time. In the vertical direction of the pants-shaped absorbent article 1 (see FIG. 1), the waist opening 1a side is defined as the "upper side" and the inseam side (inseam 10 m side) is defined as the "lower side" of the absorbent article 1. .. In the anterior-posterior direction, the anterior side is also the "ventral side" and the posterior side is also the "dorsal side".

FIG. 2 is a plan view of the absorbent article 1 in a separated plane state and an elongated state as viewed from the skin side. In the "separation plane state", the

side end joints

10e and 10e of the left and right end portions of the pants-type absorbent article 1 are unraveled, and the ventral waist circumference portion 10f and the dorsal waist circumference portion 10b are separated from each other. It is in a state where it opens in the vertical direction and spreads out in a plane. The "stretched state" is a state in which the absorbent article 1 is stretched without wrinkles, specifically, the dimensions of each member constituting the diaper 1 (for example, the exterior body 10 and the absorbent body 20 described later) are the dimensions thereof. It refers to a state in which the member is stretched to a length that matches or is close to the dimensions of the single member. The absorbent article 1 in the separated plane state and the extended state has a "longitudinal direction", a "left-right direction", and a "thickness direction" orthogonal to each other, and the "longitudinal direction" of the absorbent article 1 is the development of FIG. Along the "vertical direction" of the absorbent article 1 in a state and a natural state, in the "thickness direction" of the absorbent article 1 shown in FIG. 2, the side in contact with the wearer's skin is called the "skin side", and the skin. The opposite side is referred to as the "non-skin side" and is along the "front-back direction" of the absorbent article 1 in the unfolded and natural state of FIG. Further, one side in the left-right direction is defined as the "left side" for the wearing wearer, and the other side in the left-right direction is defined as the "right side" for the wearing wearer. The CC line in FIG. 2 and the like is a center line in the left-right direction.

The absorbent article 1 is a so-called two-piece type shorts type napkin, and has an exterior body 10 and an absorbent main body 20 that absorbs excrement such as urine. In the following description, a two-piece type shorts type napkin (pants type absorbent article) will be described, but a so-called three-piece type shorts type napkin in which the ventral waistline portion and the dorsal waistline portion are arranged separately. (Pants type absorbent article) may be used.

The absorbent article 1 has a ventral waist circumference portion 10f that covers the wearer's ventral side, a crotch lower portion 10 m located in the inseam of the wearer, and a dorsal waist circumference portion 10b that covers the wearer's back side. The inseam portion 10m is a region interposed between the ventral waist circumference portion 10f and the dorsal waist circumference portion 10b in the longitudinal direction.

The exterior body 10 of the absorbent article 1 in the separated flat state and the extended state is a member forming the outer shape of the absorbent article 1 and has a substantially hourglass shape in a plan view. That is, the central portion in the longitudinal direction is recessed inward in the left-right direction. When this recessed portion is molded into a pants shape, it becomes a pair of leg-circumferential openings 1b. Further, the exterior body 10 has a one-side extending portion 10L located on the outer side of one side in the left-right direction of the absorbent main body 20, and a other-side extending portion 10R located on the outer side of the other side.

As shown in FIG. 2, in the absorbent article 1 in the separated plane state and the extended state, the ventral waist circumference portion 10f is located on one end side in the longitudinal direction of the absorbent body 20, and the dorsal waist circumference portion 10b is absorbent. It is located on the other end side of the main body 20 in the longitudinal direction. The ventral waist circumference portion 10f and the dorsal waist circumference portion 10b each have side end joint portions 10e for joining the ventral waist circumference portion 10f and the dorsal waist circumference portion 10b at both end portions. The absorbent article 1 in the separated plane state and the extended state shown in FIG. 2 is folded in half by a folding line CL provided in the substantially central portion in the longitudinal direction, that is, the crotch lower portion 10 m, along the left-right direction, and the side end joint portion. At 10e, the side end portion of the ventral waist circumference portion 10f and the side end portion of the dorsal waist circumference portion 10b are joined to form a pants type. For the side end bonding portion 10e, well-known bonding means such as ultrasonic bonding, adhesive, and welding bonding can be used. When molded into a pants shape, it becomes a pants type absorbent article having a waist circumference opening 1a and a pair of leg circumference openings 1b. The fold line CL is a substantially center of the absorbent article 1 in the longitudinal direction, and is a straight line along the left-right direction. In the pants-type absorbent article 1 shown in FIG. 1, it is the lowermost end of the diaper 1 having a folded portion, and is the end of the inseam 10 m.

<Exterior body 10>
The exterior body 10 includes an exterior top sheet 11, an exterior back sheet 12, a ventral waist circumference elastic member 13, and a dorsal waist circumference elastic member 14, and is joined and fixed to each other with a hot melt adhesive or the like.

The exterior top sheet 11 and the exterior back sheet 12 have substantially the same shape and form the outer shape of the absorbent article 1. The exterior top sheet 11 can be formed of an air-through non-woven fabric, a spunbond non-woven fabric, an SMS non-woven fabric (spunbond, meltblown, spunbond non-woven fabric), a waterproof film, or the like. The exterior back sheet 12 can be formed of an air-through non-woven fabric, a spunbond non-woven fabric, an SMS non-woven fabric (spunbond, meltblown, spunbond non-woven fabric) or the like. The ventral and dorsal outer ends (upper ends) of the exterior back sheet 12 in the longitudinal direction are folded back toward the skin, respectively, and the ventral folded-back portion 10ff and the dorsal folded portion wrapping the outer end (upper end) of the exterior top sheet 11 are folded back. It has a portion 10bf. It should be noted that the configuration may not have the ventral folded portion 10 ff and the dorsal folded portion 10 bf. However, since the absorbent article 1 includes the ventral folded-back portion 10ff and the dorsal folded-back portion 10bf, the thickness of the exterior body 10 in the waist circumference opening 1a can be increased, so that the absorbent article 1 can be passed through the waist circumference opening 1a. It becomes easy to reduce the amount of the cooling sensation agent 26 (described later) flowing out of 1.

The ventral waist circumference elastic member 13 and the dorsal waist circumference elastic member 14 are provided between the exterior top sheet 11 and the exterior back sheet 12 in the thickness direction at the ventral waist circumference portion 10f and the dorsal waist circumference portion 10b, respectively. The ventral waist circumference elastic member 13 and the dorsal waist circumference elastic member 14 are, for example, a plurality of thread rubbers. The ventral waist circumference elastic member 13 and the dorsal waist circumference elastic member 14 are joined and fixed by an adhesive such as a hot melt adhesive. The ventral waist circumference elastic member 13 and the dorsal waist circumference elastic member 14 impart elasticity in the left-right direction to the ventral waist circumference portion 10f and the dorsal waist circumference portion 10b.

In the ventral waist circumference portion 10f, it is preferable that the contraction force of the upper end portion on the waist circumference opening 1a side due to the contraction force of the ventral waist circumference elastic member 13 is larger than the contraction force of the lower end portion located near the inseam. Further, in the dorsal waist circumference portion 10b, it is preferable that the contraction force of the upper end portion of the dorsal waist circumference elastic member 14 on the waist circumference opening 1a side is larger than the contraction force of the lower end portion located near the inseam. As a result, the waist circumference opening 1a is made easier to shrink and the waist circumference opening 1a is narrowed, so that the amount of the cooling sensation 26 flowing out of the absorbent article 1 through the waist circumference opening 1a can be easily reduced. The ventral waist circumference portion 10f and the dorsal waist circumference portion 10b may be provided with an elastic sheet that expands and contracts in the left-right direction.

<Absorbable body 20>
The absorbent body 20 is joined to the skin side surface of the exterior body 10. As a method of joining the absorbent main body 20 to the exterior body 10, for example, a known connection method such as an adhesive, a heat seal, an ultrasonic seal, or a combination thereof can be exemplified.

FIG. 3 is a plan view of the absorbent main body 20 in FIG. 2, and FIG. 4 is a sectional view taken along the line AA in FIG. FIG. 3 is a plan view of the absorbent body 20 as viewed from the skin side. The absorbent body 20 includes a liquid-absorbing absorbent body (absorbable core) 22, a core wrap sheet 22a that covers the outer peripheral surface of the absorbent body 22, a first skin side sheet 24a, a second skin side sheet 24b, and a non-skin side. It includes a seat 24c, a side seat 24d, an inseam elastic member 30, and a cooling sensation agent 26. Each member is joined by an adhesive such as a hot melt adhesive or by a well-known means such as welding and crimping. Further, in the region of the absorbent body 20 where the absorbent body 22 is provided, a squeezed portion 40 having a shape along a substantially longitudinal direction squeezed from the skin side in the thickness direction is provided.

The absorber 22 is a member obtained by molding a liquid-absorbing material into a substantially rectangular shape, and can absorb excrement such as urine. As the liquid absorbent material, for example, a liquid absorbent fiber such as pulp fiber, a highly absorbent polymer or the like can be used. The shape of the absorber 22 is not necessarily limited to the shape shown in FIG. As the core wrap sheet 22a, a liquid permeable sheet such as tissue paper or non-woven fabric can be exemplified. However, a configuration that does not use these core wrap sheets 22a may be used.

The first skin-side sheet 24a is a liquid-permeable sheet member that can come into contact with the wearer's skin when worn, has a substantially rectangular shape, and has a plane size larger than that of the absorber 22. The second skin side sheet 24b is laminated on the non-skin side surface of the first skin side sheet 24a. The first skin-side sheet 24a and the second skin-side sheet 24b are provided on the skin side of the absorber 22, respectively. The first skin-side sheet 24a and the second skin-side sheet 24b are formed of, for example, a hydrophilic air-through non-woven fabric, a spunbonded non-woven fabric, or the like. It should be noted that the configuration may include only one of the first skin side sheet 24a and the second skin side sheet 24b. For example, the configuration is such that the first skin side sheet 24a located on the skin side of the absorber 22 is provided, and the sheet member (second skin side sheet 24b) is not provided between the first skin side sheet 24a and the absorber 22. Alternatively, only the core wrap sheet may be provided between the first skin side sheet 24a and the absorber 22.

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

The side sheet 24d is a substantially rectangular sheet member having a plane size larger than that of the absorber 22, and the side sheet 24d is formed of, for example, an air-through nonwoven fabric or a spunbonded nonwoven fabric. The side sheet 24d covers both ends of the absorber 22 in the left-right direction when viewed from the skin side, and the specific configuration is from one end of the absorber 22 in the left-right direction to the left-right direction of the absorber 22. Folded toward the non-skin side in the thickness direction outside the one-sided end in the above, covers the entire non-skin side surface of the absorber 22, and is outside the other side end in the left-right direction of the absorber 22 in the thickness direction. It is folded back toward the skin side and covers the other end of the absorber in the left-right direction. An elastic member 50S is fixed to the side sheet 24d on the skin side of the absorber 22. 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 cooling sensation agent 26 is provided inside the absorbent article 1, and the area where the cooling sensation agent 26 is provided (applied) is referred to as a coating area 26P. Shown by hatching in the sand. The “inside of the absorbent article 1” refers to the skin side of the exterior back sheet 12, which is the outermost sheet of the absorbent article 1. In 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 cooling 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 port (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 cooling sensation agent 26, it is preferable to provide the coating area 26P on the absorbent body 20. Further, it is more preferable that the cooling sensation 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, it is preferable that the amount of the cooling sensation agent 26 held by the first skin side sheet 24a is larger than the amount of the cooling sensation 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 cooling sensation 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 cooling sensation agent 26 held by the side sheet 24d, the possibility that the adhesiveness of an adhesive such as a hot melt adhesive for fixing the elastic member 50S to the side sheet 24d is reduced is reduced. be able to.

The cooling sensation agent 26 is a substance for reducing discomfort due to stuffiness and stickiness to the wearer, and is a substance provided with a cooling sensation stimulant that stimulates the wearer's sense of temperature. As the cooling sensation stimulant of the present embodiment, a substance capable of exhibiting a cooling sensation effect in a worn state is used. For example, in a state where excrement such as urine and menstrual blood is excreted and the excrement is absorbed by the absorbent body 20, the wearer is likely to get discomfort due to the excrement and is less likely to feel the effect of the cooling agent 26. .. On the other hand, the cooling sensation stimulant used in the cooling sensation agent 26 of the present embodiment does not exert its effect in response to the water contained in the excrement, and when the wearer wears the absorbent article 1. By using a substance capable of obtaining a cooling sensation effect from the above, the wearer can easily feel the effect of the cooling sensation agent 26 and can easily obtain a refreshing sensation due to the cooling sensation agent 26. Since the cooling sensation 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 cooling sensation stimulant is preferably derived from a plant from the viewpoint of the wearer's sense of security. Examples of the cooling sensation stimulant include menthol (eg, l-menthol, etc.); menthol derivatives (eg, menthol lactate, menthylglyceryl ether, etc.); methyl salicylate; essential oils derived from plants such as mint and eucalyptus.

The cooling sensation stimulant of the cooling sensation agent 26 is preferably one that stimulates temperature-sensitive TRP channels. For example, TRPM8, which is one of the temperature-sensitive TRP channels, is a cooling stimulus receptor which is a cooling sensation sensor. Menthol (eg, l-menthol) and its derivatives (eg, menthol lactate), etc., activate TRPM8 to cause the cooling sensation sensor to react even if the temperature does not actually drop, so that the wearer is cool. Can be given. That is, it is preferable that the wearer feels cold rather than absorbing heat by itself to lower the temperature. Therefore, the wearer can feel a feeling of coldness without excessively cooling the skin.

In addition, the cooling sensation 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 cooling sensation agent 26 comes into direct contact with the wearer's skin after vaporization and has its main effect. Demonstrate. That is, when the cooling sensation 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 cooling sensation agent 26 on the skin.

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

Examples of the oil-friendly 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.

<<< Individual packaging 100 >>>
The absorbent article 1 is packaged in the packaging material 101 to become an individual package 100. FIG. 5 is a plan view of the individual package 100. The absorbent article 1 in the individual package 100 is 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 individually packaged body 100 in the packaged state, the folding direction of the packaging material 101 is along the vertical direction of the individual packaging body 100 and the absorbent article 1, and the orthogonal direction of the packaging material 101 is the direction of the individual packaging body 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.

<Absorbable article 1 in a folded state>
The absorbent article 1 in the folded state means a state in which the absorbent article 1 in the unfolded state is folded at a folded portion along the vertical direction and the horizontal direction. FIG. 6 is a schematic view of the absorbent article 1 in the unfolded state as viewed from the dorsal side. For convenience, the one-side leg circumference opening 1b in FIGS. 6 to 12 is shown by a diagonally downward diagonally downward portion.

The absorbent article 1 in the folded state (see FIG. 8) is formed by folding at the folding reference positions B1, B2, and B3 from the unfolded state shown in FIG. The folding reference positions B1, B2, and B3 are positions that serve as reference points (fulcrums) for folding the absorbent article 1, respectively. The absorbent article 1 (individual package 100) is first folded inward in the left-right direction at the folding reference positions B1 and B2 from the unfolded state shown in FIG. 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 in the unfolded state.

From the unfolded state shown in FIG. 6, first, of the one-side extending portion 10L, the portion outside the folding reference position B1 in the left-right direction is folded toward the dorsal side to reach the state shown in FIG. By folding the portion of the other side extending portion 10R outside the folding reference position B2 in the left-right direction toward the dorsal side, the state shown in FIG. 7B is obtained. FIG. 7A is a diagram showing a state in which the absorbent article 1 of FIG. 6 is folded at the folding reference position B1. FIG. 7B is a diagram showing a state in which the absorbent article 1 of FIG. 7A is folded at the folding reference position B2. As shown in FIG. 7B, by folding at the folding reference positions B1 and B2, a part of the folded part 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. Either the one-side extension portion 10L or the other-side extension portion 10R may be folded first.

It should be noted that the absorbent article is in a state where the portion of the one-side extension portion 10L and the portion of the other-side extension portion 10R are folded at the folding reference position B1 and the folding reference position B2 shown in FIGS. 7A and 7B, respectively (FIG. 7B). When 1 is viewed from the upper side (for example, the dorsal side) in the thickness direction (front-back direction), the one-sided end in the left-right direction is called "one-side folding portion LB", and the one-side folding portion LB is the most opposite end in the left-right direction. Is referred to as "the other side folding portion RB", and the one side folding portion LB and the other side folding portion RB are also referred to as "left and 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 outward in the left-right direction from the folding reference position B1 and the folding reference position B2, respectively. ..
In the unfolded state, the one-side folding portion LB overlaps the folding reference position B1 in the front-rear direction (thickness direction), and the other-side folding portion RB overlaps the folding reference position B2 in the front-rear direction (thickness direction). overlapping. 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. 7B, the portion lower (inseam side) than the folding reference position B3 in the vertical direction is folded toward the upper side (girth opening 1a side), so that FIG. 8 shows. It becomes the absorbent article 1 in the folded state shown. FIG. 8 is a diagram showing an absorbent article 1 in a folded state. When the absorbent article 1 in the folded state in which the absorbent article 1 is folded in the 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). 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 unfolded state, the vertically folded portion BL overlaps with the folding reference position B3 in the front-rear direction (thickness direction). 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 at the portion intersecting the squeezing portion 40 having high rigidity, it becomes easy to make a so-called folding habit in the absorber 22, and it becomes easy to maintain the folded state of the absorbent article 1, so that it is provided inside the absorbent article 1. It becomes easy to reduce the possibility that the cooling sensation agent 26 volatilizes through the waist circumference opening 1a.

<Packaging method using packaging material 101>
A method of packaging the folded absorbent article 1 with the packaging material 101 will be described. FIG. 10 is a diagram showing a state of the first packaging process. In the first packaging step, as shown in FIG. 10, a rectangular packaging material 101 having a size larger than that of the folded absorbent article 1 is horizontally spread, and the folded absorbent article 1 is located in the substantially central portion of the packaging material 101. Is placed. At this time, among the absorbent articles 1 in the folded state, the waist opening 1a (

girth portion

10f, 10b) side is the side in contact with the packaging material 101 (lower side) in the thickness direction (front-back direction), and the crotch lower portion 10 m. The side is the upper side. The first folding reference position L1 shown in FIG. 10 is a reference position for folding the packaging material 101 in the second packaging process, and the second folding reference position L2 is for folding the packaging material 101 in the third packaging process. This is the reference position. 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 cooling agent 26 to permeate (so-called high gas barrier property), so that the cooling agent 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, a sheet member having an oxygen permeability in the thickness direction of 200 cc / m ² / day / atm or less at 23 ° C. is used. Since the permeability of the volatile substance in the thickness direction of the packaging material 101 is substantially proportional to the oxygen permeability, the degree to which the volatile substance permeates in the thickness direction of the packaging material 101 is determined by the thickness of the packaging material 101. It is specified using the oxygen permeability in the longitudinal direction.

As the packaging material 101, for example, a sheet member made of EVOH resin (ethylene-vinyl alcohol copolymer resin), PET (polyester), polyvinyl alcohol, polyvinyl chloride (PVC), nylon, or the like can be used. The packaging material 101 of the present embodiment is a sheet of a multi-layer film material of PE / admer / EVOH / admer / PE containing an EVOH resin (ethylene-vinyl alcohol copolymer resin) and has an oxygen permeability of 2.0 cc. / M ² / day / atm. 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.

Specifically, first, a filter paper dipped in menthol, which is a cooling sensation agent 26, and a packaging material 101 made of EVOH resin are prepared, and the weights of the filter paper and the packaging material 101 are measured. Subsequently, a filter paper containing menthol is placed on the packaging material 101 made of EVOH resin, folded in three, and the weight of the sample A in a state of being sealed with a sealing member is measured. By dividing the weight of the filter paper containing no menthol from the weight of the sample A in this state by the weight of the packaging material 101, the weight of the menthol contained in the filter paper can be obtained. Then, after a predetermined time (for example, 1 week and 4 weeks in a state of being placed in a constant temperature and humidity chamber at 40 ° C. and 70%) under predetermined conditions, the weight of the sample A was measured, and the weight decreased from before the predetermined time. By calculating the weight, the outflow amount of menthol, which is the cooling sensation agent 26, can be obtained. Further, the reduction rate of menthol can be calculated by comparing the weight of menthol after the lapse of a predetermined time with the weight of the menthol before the lapse of a predetermined time. It is preferable to measure the amount of menthol outflow and the like by a predetermined number (for example, 10 times) and obtain an average value thereof.

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

FIG. 9 is a diagram showing the measurement result of the outflow amount of menthol. In FIG. 9, each weight and ratio show an average value. The weight of menthol at the start of measurement of sample A (EVOH resin, packaging material 101) was 0.5 g, and the weight of menthol after 1 week was reduced by 2% from the start of measurement, and after 4 weeks had passed. The weight of menthol is reduced by 2% from the start of the measurement. The weight of menthol at the start of measurement of sample B (sheet made of PET) is 0.5 g, the weight of menthol at the start of measurement is 0.5 g, and the weight of menthol after one week is measured. It is reduced by 2% from the start and the weight of menthol after 4 weeks is reduced by 2% from the start of measurement. The weight of menthol at the start of measurement of sample C (sheet made of PVC) was 0.5 g, and the weight of menthol after 1 week was reduced by 6% from the start of measurement, and after 4 weeks had passed. The weight of menthol is reduced by 10% from the start of the measurement. The weight of menthol at the start of measurement of sample D (sheet made of PE) was 0.5 g, and the weight of menthol after 1 week was reduced by 32% from the start of measurement, and after 4 weeks had passed. The weight of menthol is reduced by 98% from the start of measurement.

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

Comparing the weight of the cooling sensation agent 26 before the lapse of the predetermined time with the weight of the cooling sensation agent 26 after the lapse of the predetermined time of the samples A to D, if the reduction rate of menthol is 10% or less, the wearer is determined. When the cooling agent 26 is attached, it is easy to recognize at the crotch portion (the portion that comes into contact with the absorbent body 20). Regarding the weight of the cooling agent 26 after 4 hours of the samples A to D, from a sheet made of EVOH resin having an oxygen permeability of 200 cc / m ² / day / atm or less, a sheet made of PET, a sheet made of aluminum, and PVC. The result was that the sheet made of PE having a predetermined weight of menthol remaining, whereas the sheet made of PE having an oxygen permeability higher than 200 cc / m ² / day / atm had almost no menthol remaining. .. Further, the sheet made of EVOH resin, the sheet made of PET, and the sheet made of PVC have a small change in the reduction rate of menthol after 1 week and 4 weeks, whereas the sheet made of PE has a small change after 1 week. Since the change in the rate of decrease in menthol after 4 weeks is large, menthol is flowing out through the PE sheet over time.

From the results of the outflow amount of the cooling sensation agents 26 of the samples A to D, when a sheet (sample C) made of polyethylene having an oxygen permeability of 200 cc / m ² / day / atm is used as the packaging material 101, a cooling sensation is felt. While it has a gas barrier property that allows the effect of the agent 26 to be felt, when a sheet made of PE (sample D) is used as the packaging material 101, it has a gas barrier property that allows the effect of the cooling sensation agent 26 to be felt. It turns out that there is no such thing. Therefore, as the packaging material 101, 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.

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 it from the side of the lower crotch 10 m, the state of the second packaging step shown in FIG. 11 is obtained. FIG. 11 is a diagram showing a state of the second packaging process. In FIG. 11, the folded first folded portion 101L is shown by an oblique line portion diagonally downward to the left. As shown in FIG. 11, in the second packaging step, by setting the folding reference position L1 as one end in the left-right direction of the absorbent article 1, one side in the left-right direction is the absorbent article 1 and the packaging material 101. It is possible to make a state where there is almost no gap (small gap) between and. 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".

In the second packaging step, 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. The adhesive 101h is an adhesive portion for joining the first folded portion 101L and the second folded portion 101R to form the joined portion 102. The adhesive 101h prevents foreign matter from entering the inside of the individual packaging body 100, and reduces the risk of the cooling sensation 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-back 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-back portion 101L and the second folded-back portion 101R are formed. By folding the folded absorbent article 1 so as to cover it from the end side of the crotch portion 10 m, the state of the third packaging step shown in FIG. 12 is obtained. FIG. 12 is a diagram showing a state of the third packaging process. In FIG. 12, the folded second folded portion 101R is shown by a diagonally downward diagonally downward portion. As shown in FIG. 12, in the third packaging step, by setting the folding reference position L2 as the other end in the left-right direction of the absorbent article 1, the other side in the left-right direction is the absorbent article 1 and the packaging material 101. It is possible to make a state where there is almost no gap (small gap) between and. 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".

In the third packaging step, 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 one-side end portion of the second folded portion 101R in the left-right direction are overlapped with each other. 2 In the packaging process, the inner joint portion 102 is formed by joining with the adhesive 101h provided on the outer surface of the first folded portion 101L. 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). That is, the inner joint portion 102 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 third packaging step, the packaging material 101 is provided 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 present embodiment, in the second packaging step, the first folded portion 101L of the packaging material 101 is folded at the folding reference position L1, and in the third packaging step, the second folded portion 101R of the packaging material 101 is folded at the folding reference position L2. I broke it, but it is not limited to this. The second folded portion 101R of the packaging material 101 may be folded in the second packaging step, and the first folded portion 101L may be folded in the third packaging step.

Finally, in the fourth packaging process, a pair of end joints 103 are formed. One side end joint 103a and the other side end joint 103b are formed at one end and the other end of the packaging material 101 in the vertical direction (orthogonal direction), respectively. The one-side end joint 103a and the other-side end joint 103b are joints formed by welding with heat and pressure, respectively. 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.

<Individual packaging 100 in the packaged state>
The individual package 100 of the absorbent article 1 such as a sanitary napkin is desired to have a compact shape for the reason of portability and the like, and the cooling agent of the absorbent article 1 taken out from the compact shape by the wearer. It is desired that the effect of a volatile substance such as 26 can be felt when worn.
Volatiles such as the cooling agent 26 provided inside the absorbent article 1 tend to flow out of the absorbent article 1 from the waist opening 1a and the leg opening 1b that are open as “openings”.

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

Usually, the pants-type absorbent article is provided with leg circumference openings 1b toward both outer sides in the left-right direction orthogonal to the vertical direction. Therefore, in the left-right direction, the one-side folding portion LC1 of the packaging material 101 located outside the absorbent article 1 is along the vertical direction of the absorbent article 1, so that the oxygen permeability is 200 cc / m ² / day / atm. Since the one-side folding portion LC1 of the following packaging material 101 can cover at least a part of the one-side leg circumference opening 1b in the left-right direction, the cooling agent 26 flowing out from the one-side leg circumference opening 1b It can play the role of a lid that reduces the outflow of the individual package 100 to the outside.

If a joint portion in which the packaging materials 101 along the vertical direction are joined to each other is provided on one side of the absorbent article 1 in the left-right direction, the cooling sensation agent 26 will flow out from the gap between the joint portions. There is a fear. On the other hand, like the absorbent article 1, the one-side folded portion LC1 of the seamless packaging material 101 having an oxygen permeability of 200 cc / m ² / day / atm or less is along the vertical direction of the absorbent article 1. By being provided on one side of the absorbent article 1, the possibility that the cooling sensation agent 26 flowing out from the leg circumference opening 1b on one side may flow out to the outside of the individual package 100 can be reduced. By reducing the possibility that the cooling sensation agent 26 flowing out from the leg circumference opening 1b on one side flows out to the outside of the individual packaging body 100, the amount of the cooling sensation agent 26 inside the individual packaging body 100 may decrease. It is possible to make it easier for the wearer to feel the effect of the cooling sensation agent 26 when the individual package 100 is opened or when the absorbent article 1 is worn.

Further, the absorbent article 1 in the folded state is provided, and the one-side folding portion LC1 along the vertical direction is provided on one side of the absorbent article 1 in the left-right direction, so that one side of the absorbent article 1 in the left-right direction is provided. The length of the individual package 100 in the left-right direction can be shortened as compared with the case of providing a joint portion in which the package materials 101 are joined to each other along the vertical direction, and the individual package 100 can be made into a more compact shape. Can be done. That is, the difference between the length of the absorbent article 1 in the folded state in the left-right direction and the length of the individual package 100 in the left-right direction can be further shortened. At this time, it is preferable that the absorbent article 1 in the packaged state (folded state) is in contact with the packaging material 101 on at least one side or the other side in the left-right direction.

Further, when the cooling sensation agent 26 contains a volatile solvent and is vaporized in a state containing the cooling sensation stimulant, there is a possibility that the vaporization of the cooling sensation agent 26 is promoted by external stimuli, circulation of outside air, and the like. There is. On the other hand, by making the individual package 100 into a compact shape and making the difference between the left-right length of the folded absorbent article 1 and the left-right length of the individual package 100 shorter, the individual package 100 The movement of the absorbent article 1 with respect to the package 101 can be reduced inside the package 101. As a result, it becomes easy to reduce the vaporization of the cooling sensation agent 26, and it becomes easy to make the wearer feel the effect of the cooling sensation agent 26. The "outflow" of the cooling sensation agent 26 includes not only the outflow of the cooling sensation agent 26 in a liquid or solid state but also the outflow of the cooling sensation agent 26 in a vaporized state.

Since the absorbent article 1 has a pair of leg-circumferential openings 1b that are open toward both sides in the left-right direction, and the packaging material 101 includes not only the one-side folding portion LC1 but also the other-side folding portion LC2. The cooling sensation 26 flowing out from the leg circumference opening 1b on one side in the left-right direction of the absorbent article 1 is reduced from flowing out to the outside of the individual package 100, and the leg circumference on the other side in the left-right direction is reduced. It is possible to reduce the outflow of the cooling sensation agent 26 flowing out from the opening 1b to the outside of the individual package 100. Therefore, when the individual package 100 is opened or the absorbent article 1 is worn, the wearer can more easily feel the effect of the cooling sensation agent 26. Since the individual package 100 has a shape substantially symmetrical in the left-right direction (orthogonal direction), the characteristics of the one-side folded portion LC1 are the same as those of the other-side folded portion LC2, which will be described later. A detailed description will be omitted.

In the absorbent article 1 in the unfolded state and the natural state, it is preferable that the cooling sensation agent 26 is provided on the inseam side of the vertically folded portion BL in the vertical direction. FIG. 3 shows the position corresponding to the vertically folded portion BL in the absorbent main body 20 of the absorbent article 1 in the unfolded state and the natural state. The cooling sensation agent 26 provided on the inseam side of the vertically folded portion BL of the absorbent article 1 in the unfolded state and the natural state is sandwiched between the vertically folded portion BL and the inseam 10 m in the folded state, and thus the cooling sensation agent 26. Can reduce the risk of flowing out of the absorbent article 1 and further reduce the cooling sensation 26 flowing out of the individual package 100.

Further, among the absorbent articles 1 in the unfolded state and the natural state, it is preferable that the cooling sensation agent 26 is provided inside the left and right folding portions LB and RB provided outside the absorber 22 in the left-right direction. .. As shown in FIG. 6 and the like, the left and right folded portions LB and RB of the absorbent article 1 are clearly outside the absorbent body 22 because they are outside the absorbent main body 20 in the left-right direction. In the folded state of the absorbent article 1, in the left-right direction, the cooling sensation agent 26 provided inside the left-right folding portions LB and RB is folded by the left-right folding portions LB and RB, so that the cooling sensation agent 26 is around the legs. The route for flowing out from the opening 1b can be narrowed, the risk of the cooling sensation 26 flowing out of the absorbent article 1 can be reduced, and the cooling sensation 26 flowing out of the individual package 100 can be reduced. Can be reduced.

As shown in FIG. 5 and the like, the individually packaged body 100 in the packaged state has an end joint 103 along the left-right direction (orthogonal direction). As described above, in order to put the individual packaging body 100 in a sealed state,

end joining portions

103a and 103b for joining the packaging materials 101 to each other are provided at both ends in the vertical direction (folding direction), respectively. Inside the packaging material 101 of the individual package 100, when the absorbent article 1 is arranged in the central portion in the vertical direction of the individual package 100, the longest distance between the one-side folded portion LC1 and the absorbent article 1 is , It is preferable that it is shorter than the longest distance between the end joint 103a (or 103b) and the absorbent article 1. For example, as shown in FIG. 5, when the absorbent article 1 is arranged in the central portion in the vertical direction of the individual package 100 inside the individual package 100, one side LC1 and the absorbent article 1 are left and right. The longest distance in the direction is shorter than the longest distance X in the vertical direction between the end joint 103a (or 103b) and the absorbent article 1. In the present embodiment, the end joint portion 103a (103b) and the absorbent article 1 are separated by a predetermined distance (longest distance X) in the vertical direction, whereas the one-side folding portion LC1 is separated in the left-right direction. The absorbent article 1 is in contact with or close to the absorbent article 1, and the distance between the one-side folded portion LC1 and the absorbent article 1 is very short and close to zero. Therefore, when the absorbent article 1 is arranged in the central portion in the vertical direction of the individual package 100, the longest distance between the one-side folded portion LC1 and the absorbent article 1 is clearly the end joint portion 103a and the absorbent article 1. It is shorter than the longest distance X to article 1. As a result, the longest distance between the one-side folded portion LC1 and the absorbent article 1 is longer than the longest distance X between the end joint portion 103a and the absorbent article 1, and the one-side folded portion LC1 and the absorbent article 1 are absorbed in the left-right direction. Since the space between the sex article 1 and the sex article 1 can be made narrower, the circulation of air that further promotes the volatilization of the cooling sensation agent 26 is reduced, and the absorbent article 1 is introduced into the packaging material 101 through the leg circumference opening 1b. The amount of the cooling sensation agent 26 that flows out can be reduced, and the amount of the cooling sensation agent 26 that flows out to the outside of the packaging material 101 (individual packaging body 100) can be easily reduced.

In FIG. 5 and the like, when the absorbent article 1 is arranged in the central portion in the vertical direction of the individual package 100, the longest distance between the one-side folded portion LC1 and the absorbent article 1 is the end joint. Although it has been described that the distance between the parts 103a (103b) and the absorbent article 1 is shorter than the longest distance X, even when the absorbent article 1 is arranged at an arbitrary position in the vertical direction of the individual package 100, one side thereof. By making the longest distance between the folded portion LC1 and the absorbent article 1 shorter than the longest distance X between the end joint portion 103a (103b) and the absorbent article 1, the package is packaged from the absorbent article 1 through the leg circumference opening 1b. It becomes easy to reduce the amount of the cooling sensation agent 26 flowing out into the material 101 and reduce the amount of the cooling sensation agent 26 flowing out to the outside of the packaging material 101 (individual packaging body 100).

As described above, the absorbent article 1 of the individually packaged body 100 in the packaged state is in a folded state in which the vertically folded portion BL and the left and right folded portions LB and RB are folded. Further, the individually packaged body 100 in the packaged state has an inner joint portion 102 provided inside the one-side folding portion LC1 (the other-side folding portion LC2) in the left-right direction (orthogonal direction). The inner joint 102 is along the vertical direction (folding direction). It is preferable that the inner joint portion 102 is provided at a position closer to the lower crotch portion 10 m than the waist circumference opening 1a in the front-rear direction of the absorbent article 1. That is, as described above (see FIGS. 10 to 12), the packaging material 101 has 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. It is preferable that the surface on which the inner joint portion 102 is not provided is located on the

waist circumference portion

10f and 10b side, and the surface on which the inner joint portion 102 is provided is provided at a position close to the crotch lower portion 10 m. ..

Generally, a shorts-type napkin (pants-type absorbent article) such as the absorbent article 1 is provided with an absorber 22 at the lower crotch 10 m in order to absorb excrement. Usually, the absorber 22 has a higher rigidity than the portion provided with the waist circumference opening 1a (the

waist circumference portion

10f, 10b).
Therefore, by providing the inner joint portion 102 at a position close to the crotch lower portion 10 m in the thickness direction, the inner joint portion 102 is formed in a more stable state, and it is easy to increase the joint strength of the inner joint portion 102. Become. Further, in the thickness direction, by providing the waist circumference opening 1a near the surface on which the inner joint portion 102 is not provided, the cooling sensation 26 flowing out from the waist circumference opening 1a passes through the inner joint portion 102 and is individually packaged 100. It is possible to reduce the risk of leaking to the outside of the.

Further, as shown in FIG. 5 and the like, in the individually packaged body 100 in the packaged state, the length N from the vertically folded portion BL to the waist circumference opening 1a (the upper end of the absorbent article 1 in the natural state) is set in the vertical direction. The absorbent article 1 is in the folded state when the length from the vertically folded portion BL to the end of the crotch portion 10 m (the lower end of the absorbent article 1 in the natural state) is M or more (N ≧ M). preferable. By folding in the vertical direction, the leg circumference opening 1b can be covered more widely and more reliably by the portion on the waist circumference opening 1a side of the vertically folded portion BL. Therefore, it is possible to reduce the possibility that the cooling sensation agent 26 will flow out from the leg circumference opening 1b.

For the individual package 100, it is preferable that the bonding strength between the packaging materials 101 at the inner bonding portion 102 is higher than the bonding strength between the packaging materials 101 of the one-side end joint portion 103a and the other side end joint portion 103b. .. Since the joint strength of the one-side end joint 103a or the other end joint 103b is lower than the joint strength of the inner joint 102 of the individual package 100 before opening, the wearer wears the

end joints

103a and 103b. It is easier to separate the joints of the packaging materials 101 of the

end joints

103a and 103b than when the joint strength of the inner joint 102 is higher than the joint strength of the inner joint 102. On the other hand, since the joint strength of the inner joint portion 102 is higher than the joint strength of the end

joint portions

103a and 103b, the joint strength of the inner joint portion 102 is lower than that of the end

joint portions

103a and 103b. Since it is possible to reduce the possibility that the packaging materials 101 of the inner joint 102 are separated from each other, the packaging material 101 of the individual package 100 after opening is opened by either one of the

end joints

103a and 103b. It becomes easier to keep it in the shape of a bag. The bag-shaped packaging material 101 can be used for carrying or disposing of the absorbent article 1 after use.

The "bonding strength" between the packaging materials 101 of the inner bonding portions 102 and the

end bonding portions

103a and 103b is the separation (peeling) between the packaging materials 101 of the bonding portions 102 and 103 for the individual packaged body 100. ) The magnitude of the force per unit area to make it. That is, the joint strength and the separation strength (peeling strength) are the same magnitude of force.

As a specific method for measuring the joint strength, first,

samples

1 and 2 having the same area are cut out from the individual package 100 to be measured. Sample 1 is a portion of the packaging material 101 provided with the inner joint portion 102, and sample 2 is a portion of the packaging material 101 provided with the end

joint portions

103a and 103b. 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 bonding strength of the inner bonding portion 102, and the average value (N) of the sample 2 is defined as the bonding strength of the

end bonding portions

103a and 103b, and both values can be compared. The joint strengths in the following description can also be compared by the same measuring method.

Further, in the packaged state, one side end joint portion 103a and the other side end portion joint portion 103b are provided on one side end portion and the other side end portion in the vertical direction of the absorbent article 1, respectively, and one side end portion joint is provided. It is preferable that the joining strength of the portion 103a is higher than the joining strength of the other side end joining portion 103b, and the waist circumference opening 1a of the absorbent article 1 is provided on one side in the vertical direction.
Regarding the vertical direction of the absorbent article 1 in the folded state, since the waist circumference opening 1a is a portion that opens toward the inside of the absorbent article 1, the cooling agent 26 is more than the vertical folded portion BL side of the absorbent article 1. Is easy to volatilize. Therefore, when the one-side end joint portion 103a has a higher joint strength than the other side end joint portion 103b, one side having a higher joint strength than when the waist circumference opening 1a is provided on the other side in the vertical direction. By directing the waist circumference opening 1a toward the end joint portion 103a, the possibility that the cooling sensation 26 leaking from the waist circumference opening 1a may flow out to the outside of the individual package 100 through the one-side end joint portion 103a is reduced. Can be done.

<Individual packaging 110 in the packaging state of another embodiment>
The individual package 110 of another embodiment will be described. FIG. 13A is a plan view of the individual package 110 of another embodiment. Regarding the following individual packaging bodies 110, the parts common to the configuration of the individual packaging body 100 of the above-described embodiment have the same reference numerals and the like, and detailed description thereof will be omitted. In the above-described embodiment, the possibility that the cooling sensation agent 26 flowing out of the absorbent article 1 from at least one leg circumference opening 1b is reduced to the outside of the individual packaging body 100 (packaging material 101) is reduced. The individual package 110 reduces the possibility that the cooling sensation 26 flowing out of the absorbent article 1 from the waist opening 1a will flow out of the individual package 110.

As shown in FIG. 13A, in the individual package 110, the left-right direction of the absorbent article 1 is along the folding direction of the packaging material 101, and the vertical direction of the absorbent article 1 is orthogonal to the folding direction of the packaging material 101. Along, the front-back direction of the absorbent article 1 is along the thickness direction of the packaging material 101. The packaging method of the individual packaging body 110 using the packaging material 101 is substantially the same as that of the individual packaging body 100 described above, but the inner joint portion 102 of the individual packaging body 110 is in the left-right direction of the absorbent article 1 (packaging material 101). The

end joints

103a and 103b are along the vertical direction of the absorbent article 1 (in the direction orthogonal to the packaging material 101). That is, the individual package 110 accommodates the absorbent article 1 in a folded state and rotated by 90 degrees, which is housed in the individual package 100 described above.

In the individual package 110, as in the above embodiment, the absorbent article 1 provided with the cooling sensation agent 26 is folded on the left and right folding portions LB, RB and the upper and lower folding portions BL, and the one-side folding portion LC1 is folded. It is packaged with the provided packaging material 101. The packaging material 101 has an oxygen permeability of 200 cc / m ² / day / atm or less, and the one-side folded portion LC1 is along the left-right direction of the absorbent article 1. Further, the one-side folding portion LC1 faces the waist circumference opening 1a of the absorbent article 1.

The one-side folded portion LC1 is along the left-right direction of the absorbent article 1 and faces the waist circumference opening 1a, so that the packaging material 101 having an oxygen permeability of 200 cc / m ² / day / atm or less is the one-side folded portion LC1. Can cover at least a part of the waist circumference opening 1a, so that the cooling sensation agent 26 flowing out from the waist circumference opening 1a can play a role of a lid for reducing the outflow of the individual package 110 to the outside. By reducing the possibility that the cooling sensation agent 26 flowing out from the waist circumference opening 1a flows out to the outside of the individual packaging body 110, the possibility that the amount of the cooling sensation agent 26 staying inside the individual packaging body 110 is reduced is reduced. Therefore, it becomes easy for the wearer to feel the effect of the cooling sensation agent 26 when the individual package 110 is opened or when the absorbent article 1 is worn.

<Individual packaging 120 in the packaging state of another embodiment>
The individual package 120 of another embodiment will be described. FIG. 13B is a plan view of the individual package 120 of another embodiment. Regarding the following individual package 120, the parts common to the configuration of the individual package 100 of the above-described embodiment have the same reference numerals and the like, and detailed description thereof will be omitted.

In the above-described embodiment, a part of the folded portion of the one-side extension portion 10L and a part of the folded portion of the other-side extension portion 10R are overlapped in the thickness direction (front-back direction). However, it is not limited to this. As shown in FIG. 13B, the portion of the one-side extension portion 10L folded at the folding reference positions B1 and B2 and the other-side extension portion 10R portion may be folded so as not to overlap in the thickness direction. As a result, the amount of the cooling sensation 26 that flows out to the outside through the leg circumference opening 1b at the folded portions LC1 and LC2 of the packaging material 101 having an oxygen permeability of 200 cc / m ² / day / atm or less is reduced. The thickness of the absorbent article 1 in the folded state can be made smaller, and the individual package 100 can be made more compact.

<<< Package 200 >>
The plurality of individual packages 100 may be sold and distributed as packages 200 housed in the bag 201. FIG. 14A is a schematic perspective view of the package 200. FIG. 14B is a diagram illustrating the package 200 as seen from the side surface 200C side.

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

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

As described above, by using the gas barrier bag body 201 while reducing the risk of the cooling sensation agent 26 flowing out from the individual packaging body 100, even if the cooling sensation agent 26 has flowed out from the individual packaging body 100. Since the risk of the cooling sensation 26 flowing out through the bag 201 can be reduced, the wearer can reduce the risk of the cooling sensation 26 flowing out to the outside when the package 200 and the individual package 100 are opened or when the absorbent article 1 is worn. You can make it easier to feel the effect.

It is preferable that the oxygen permeability of the packaging material 101 of the individual package 100 is lower than the oxygen permeability of the bag 201 of the package 200. As described above, the oxygen permeability of the packaging material 101 of the individual package 100 is 2.0 cc / m ² / day / atm, and the oxygen permeability of the bag 201 of the package 200 is 80 cc / m ² / day / atm. Is. As a result, the amount of the cooling sensation 26 flowing out from the individual package 100 can be easily reduced as compared with the case where the oxygen permeability of the packaging material 101 is higher than the oxygen permeability of the bag 201. Not only is it easy to maintain the cooling sensation 26 inside, but it is also easy to reduce the amount of the cooling sensation 26 existing outside the individual package 100 and inside the bag 201, reducing the volatilization of the cooling sensation 26. Therefore, it becomes easy for the wearer to feel the effect of the cooling sensation agent 26.

In the individual package 100, the left-right end of the folded absorbent article 1 is covered with the folded portions LC1 and LC2 of the packaging material 101, whereas the folded absorbent article 1 is vertically oriented. Since the ends are joined by the

end joints

103a and 103b, the cooling sensation 26 may flow out from the

end joints

103a and 103b rather than the folded parts LC1 and LC2. In particular, the cooling sensation agent 26 may flow out of the other side end joint 103b, which has a lower joint strength than the one side end joint 103a, through the other end joint 103b.

On the other hand, the individual package 100 includes one side end joint portion 103a and the other side end portion joint portion 103b at one side end portion and the other side end portion in the vertical direction of the absorbent article 1, respectively. .. The joint strength of the one-side end joint portion 103a is higher than the joint strength of the other side end portion joint portion 103b. Such an individual package 100 is housed so that the vertical direction of the package 200 and the vertical direction of the absorbent article 1 are aligned, and the other end joint portion 103b is the bottom surface of the bag body 201 (bottom surface of the package 200). It is preferable that it is in contact with 200E). That is, in the present embodiment, as shown in FIG. 14B, two individual packages 100 are vertically stacked and housed, and the vertical direction of the package 200 and the

end joints

103a and 103b are orthogonal to each other. The other side end joint 103b, which has a weaker joint strength than the one side end joint 103a of the individual package 100 housed in the lower side, is in contact with the bottom surface 200E.

Since the packaging material 101 is a soft sheet-like member, the portion outside the

end joints

103a and 103b in the vertical direction of the individual package 100 has lower rigidity and is softer than the

end joints

103a and 103b. Therefore, as shown in FIG. 14B, when the individual package 100 is housed so that the vertical direction of the package 200 and the vertical direction of the absorbent article 1 are aligned with each other, the individual package house housed at the lowermost side of the package 200 is housed. The portion of 100 below the other side end joint 103b is bent in the left-right direction of the package 200 (thickness direction of the individual package 100) due to the weight of the two individual packages 100, and the other end is joined. The portion 103b easily comes into contact with the bottom surface 200E. Even when the joint strength of the other side end joint portion 103b of the individual package 100 is weaker than the joint strength of the one side end portion joint portion 103a, the other side end portion joint portion 103b comes into contact with the bottom surface 200E. A gap is less likely to occur between the other side end joint 103b and the bottom surface of the bag 201, and the risk of the cooling sensation 26 flowing out of the individual package 100 from the other side end joint 103b is reduced. Can be done.

Regarding the package 200, the configuration for accommodating a plurality of individual packages 100 has been described, but the present invention is not limited to this. The package 200 may be configured to accommodate one individual package 100. Further, the package 200 may be configured to accommodate a plurality of (or one) individual packages 110.

=== 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 packaging material 101 may be an individual packaging body 100 having only one folded portion, or the packaging material 101 may be an individual packaging body 100 having three or more folded portions. 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 upper and lower folding portions RB, or may be folded by the upper and lower folding portions 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, in the individually packaged body 100 in the packaged state, the length N from the vertically folded portion BL to the waist circumference opening 1a is the length M from the vertically folded portion BL to the end of the crotch portion 10 m in the vertical direction. The absorbent article 1 in the folded state in the above (N ≧ M) state is defined, but the present invention is not limited to this. In the individually packaged body 100 in the packaged state, the length from the vertically folded portion BL to the end of the crotch portion 10 m may be longer than the length from the vertically folded portion BL to the waist circumference opening 1a in the vertical direction (M> N). ). At this time, it is more preferable that the inner joint portion 102 is provided at a position closer to the lower crotch portion 10 m than the waist circumference opening 1a in the thickness direction of the individual package 100 (the front-back direction of the absorbent article 1). .. As a result, the lower crotch portion 10 m covers the waist circumference opening 1a, and the waist circumference opening 1a can be sandwiched between the lower crotch portion 10 m and the packaging material 101, thus reducing the risk of the cooling sensation 26 flowing out from the waist circumference opening 1a. be able to.
