Detailed Description
In particular, the present disclosure relates to the following technical solutions.
[ solution 1]
An individual package of an absorbent article comprising an absorbent main body including a liquid-permeable sheet, an absorbent body, a liquid-impermeable sheet, and a fixing portion for fixing the absorbent article to a garment, wherein the absorbent article and a cooling composition are contained in the individual package so as to have a temperature of 100cc/m at 23 ℃ 2 A packaging sheet package having an oxygen permeability of 50% or more and 60% or less by mass, wherein the cooling composition contains a low-attenuation cooling agent having an attenuation rate (temperature: 40 ℃, relative humidity: 70% RH, time: 8 hours) of 20% or more and 60% or less by mass.
In the individual package of the absorbent article, the package sheet has a predetermined oxygen permeability, that is, has air-tightness. Therefore, when the absorbent article is stored, even when the individual package is stored for a long time or when the individual package is stored in a hot area, the refreshing composition is less likely to volatilize from the individual package.
In addition, in the individual package, since the package sheet has airtightness, generally, the vaporized component tends to easily plasticize the fixed portion. However, in the above-described absorbent articles, the cooling composition contains a predetermined amount of a predetermined low-attenuation cooling agent. Therefore, when the individual package is stored, the vaporized low-attenuation refreshing agent is less likely to move to the fixing portion, and the fixing portion is less likely to be plasticized.
Further, in the above-described individual package, when the absorbent article is used, the absorbent article includes a cooling composition containing a predetermined amount of a predetermined low-attenuation cooling agent. Therefore, even when the absorbent article is worn for a long time, the wearer can continue to feel cool.
Further, in the individual package, when the absorbent article is used, the low-attenuation refreshing agent in the refreshing composition is less likely to vaporize during use, and the fixed portion is less likely to be plasticized. Therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be continued to be excellent.
[ solution 2]
The individual package according to claim 1, wherein the absorbent main body includes a cooling composition at a position closer to the liquid-permeable sheet than the liquid-impermeable sheet in the unfolded state of the absorbent article.
In the individual package, the absorbent body includes the refreshing composition at a position closer to the liquid-permeable sheet than the liquid-impermeable sheet in the unfolded state of the absorbent article, and therefore the fixing portion is not easily plasticized by the liquid refreshing composition. Therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 3]
The individual package according to claim 1 or 2, wherein the cooling composition contains a high-attenuation cooling agent having an attenuation rate of more than 60% by mass (temperature: 40 ℃, relative humidity: 70% RH, time: 8 hours) in a proportion of 20% or less.
In the above-described individual packages, since the cooling composition contains a predetermined amount of a predetermined high-attenuation cooling agent, the absorbent article is apt to make the wearer feel cooling from the initial stage of wearing the absorbent article.
[ solution 4]
The individual package according to any one of claims 1 to 3, wherein the cooling composition contains a flavor at a ratio of 30% or less.
The fragrance is volatile and tends to plasticize the fixed portion.
In the above-described individual package, since the cooling composition contains a predetermined amount of the perfume, the perfume does not easily plasticize the fixing portion. Therefore, even when the absorbent article is worn for a long time, the fragrance can be given to the wearer, the fixing portion is less likely to be peeled off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 5]
The individual package according to claim 4, wherein the perfume comprises linalool, methyl dihydrojasmonate, and cis-3-hexenol.
In the above-mentioned individual package, the cooling composition contains a predetermined flavor. The predetermined perfume can soothe and cure the mood of the user and can provide comfort. Therefore, a user who uses the individual package and the absorbent article can alleviate discomfort during a physiological period by smelling the fragrance of the perfume before use, and can also feel a sense of expectation about a cooling effect of the cooling composition during wearing.
[ solution 6]
The individual package according to claim 4 or 5, wherein the flavor comprises clove, cinnamon, and β -caryophyllene.
In the above-mentioned individual package, the cooling composition contains a predetermined flavor. The predetermined perfume has an activating action of stimulating and activating the human body and mind, a blood circulation promoting action, and the like. Therefore, a user who uses the individual package and the absorbent article can get a chance to change the negative emotion during the physiological period by smelling the fragrance of the perfume before use, and can also feel a sense of expectation for the cooling effect of the cooling composition during wearing.
[ solution 7]
The individual package according to any one of claims 1 to 6, wherein the cooling composition contains no lubricant or contains a lubricant at a ratio of 30% or less.
The lubricant is volatile, and may plasticize the fixed portion. In the above absorbent article, since the cooling composition contains no lubricant or contains a predetermined amount of lubricant, the lubricant does not easily plasticize the fixing portion. Therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 8]
The individual package according to any one of claims 1 to 7, wherein the absorbent main body is provided at a ratio of 7g/m 2 ～14g/m 2 Comprises the cooling composition described above per unit area weight.
In the individual package, the absorbent body includes a predetermined amount of a cooling composition that includes a predetermined amount of a low-attenuation cooling agent. In the above-described individual package, even when the cooling composition is present in an amount larger than usual, the cooling composition does not easily plasticize the fixed portion. Therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 9]
The individual package according to any one of claims 1 to 8, wherein the cooling composition has a viscosity of 100 to 600 mPas (30 ℃).
In the above-mentioned individual package, the viscosity of the cooling composition is in a predetermined range. Therefore, the refreshing composition is less likely to move to the fixed portion while remaining in a liquid state, and the fixed portion is less likely to be plasticized by the liquid refreshing composition. As a result, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be continued to be excellent.
[ solution 10]
The individual package according to any one of claims 1 to 9, wherein the cooling composition has a viscosity of 300mPa · s (30 ℃) to 600mPa · s (30 ℃).
In the above-mentioned individual package, the cooling composition has a predetermined viscosity. Therefore, the cooling composition is less likely to move to the fixed portion while remaining in a liquid state, and the fixed portion is less likely to be plasticized by the cooling composition in a liquid state. As a result, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 11]
The individual package according to any one of claims 1 to 10, wherein the liquid-impermeable sheet does not have a vent hole.
As a liquid impermeable sheet, a sheet having air permeable holes is known. The liquid-impermeable sheet has air holes, so that moisture in the absorbent article can be easily discharged to the outside of the absorbent article through the air holes.
In an absorbent article used by being fixed to a garment, the following tendency exists: the absorbent article fixed to the clothing is also easily deformed according to the deformation of the clothing, and the liquid-impermeable sheet directly connected to the fixing portion is also easily deformed.
In the individual package, since the liquid-impermeable sheet does not have the air-permeable holes, even when the liquid-impermeable sheet is deformed during wearing, the refreshing composition is less likely to reach the fixing portion through the liquid-impermeable sheet, and the fixing portion is less likely to be plasticized. Therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to peel off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 12]
The individual package according to any one of claims 1 to 11, wherein the absorbent article has a longitudinal direction and a width direction in an expanded state thereof and has a excretory opening contact region, the absorbent main body includes a pair of longitudinally extending compressed portions which are formed by compressing the liquid-permeable sheet and the absorbent body, and are disposed at both ends in the width direction of the excretory opening contact region and extend in the longitudinal direction, and the pair of longitudinally extending compressed portions hold the cooling composition, respectively.
The pair of longitudinally extending compressed parts disposed on both sides of the excretory opening contact region of the absorbent article function as folding starting points when the absorbent article is worn, and facilitate the excretory opening contact region to contact the excretory opening of the wearer.
In the individual package, the pair of longitudinally extending compressed parts hold the cooling composition, respectively. Therefore, even when the absorbent article is worn for a long time, the cooling composition disposed in each of the pair of longitudinally extending compression portions is kept in contact with the skin of the wearer, and the wearer tends to feel cooling.
[ solution 13]
The individual package according to claim 12, wherein the pair of longitudinally extending compressed portions respectively include a high compressed portion having a relatively high degree of compression and a low compressed portion having a relatively low degree of compression.
In the above-described individual package, the pair of longitudinally extending compressed portions includes a high compressed portion and a low compressed portion, respectively. Therefore, the absorbent article described above tends to cling to the wearer's skin along the lines of the wearer's body, and tends to keep the wearer cool.
[ solution 14]
The individual package according to claim 13, wherein the absorbent main body includes a pair of widthwise extending compressed parts which are formed by compressing the liquid-permeable sheet and the absorbent body and which are disposed at both ends in the longitudinal direction of the excretion portion contact region and extend in the widthwise direction, the pair of widthwise extending compressed parts include a high compressed part having a relatively high compression degree and a low compressed part having a relatively low compression degree, respectively, and an area ratio of the high compressed part of each of the pair of widthwise extending compressed parts is higher than an area ratio of the high compressed part of each of the pair of lengthwise extending compressed parts.
In the individual package described above, since the area ratio of the high compressed portion in each of the pair of widthwise extending compressed portions is higher than the area ratio of the high compressed portion in each of the pair of lengthwise extending compressed portions, the liquid-permeable sheet and the absorbent body are less likely to be peeled off at both lengthwise end portions of the excretory opening contact region when the absorbent article is used, and the absorbent article is less likely to be twisted.
The above-described effect tends to be greater than in the case where both or one of the pair of widthwise-extending compressed portions holds the cooling composition.
[ solution 15]
The individual package according to any one of claims 1 to 14, wherein the absorbent article includes a pair of side wing portions disposed on both side portions of the absorbent main body for fixing the absorbent article to a garment, the pair of side wing portions respectively include a liquid-permeable side sheet, a liquid-impermeable side sheet, and a side wing portion fixing portion for fixing the pair of side wing portions to a garment, the absorbent main body and the pair of side wing portions respectively include the cooling composition, the cooling composition has a weight per unit area greater than the cooling composition has on the pair of side wing portions, and an absorbent main body adhesive of the absorbent main body to which the liquid-permeable sheet and the liquid-impermeable sheet are bonded has a weight per unit area greater than a weight per unit area of a side wing portion adhesive of the pair of side wing portions to which the liquid-permeable side sheet and the liquid-impermeable side sheet are bonded.
In the individual package, the cooling composition contained in the absorbent main body has a weight per unit area greater than the cooling composition contained in each of the pair of side flap portions, and the absorbent main body adhesive has a weight per unit area greater than the weight per unit area of the side flap portion adhesive. Therefore, even when the absorbent article is worn for a long time, the absorbent main body, specifically, the liquid-permeable sheet and the liquid-impermeable sheet are not easily peeled off from the wearing clothes, and the wearing feeling of the absorbent article can be maintained excellent.
[ solution 16]
The individual package according to any one of claims 1 to 15, wherein the absorbent article includes a pair of side wing portions disposed on both side portions of the absorbent main body for fixing the absorbent article to a garment, the pair of side wing portions include a liquid-permeable side sheet, a liquid-impermeable side sheet, and a side wing portion fixing portion for fixing the pair of side wing portions to a garment, respectively, the absorbent main body and the pair of side wing portions include the cooling composition, respectively, the cooling composition in the absorbent main body has a weight per unit area larger than the weight per unit area of the cooling composition in the pair of side wing portions, and the weight per unit area of the fixing portion is smaller than the weight per unit area of the side wing portion fixing portion.
In the individual package, the cooling composition contained in the absorbent article has a higher weight per unit area than the cooling composition contained in each of the pair of side flap portions. Therefore, the absorbent article can keep the wearer cool even when the absorbent article is worn for a long time. In the absorbent article, the weight per unit area of the fastening portion is smaller than the weight per unit area of the flap portion fastening portion. Therefore, in the absorbent article, even when the fixing portion is plasticized and the adhesion force thereof is reduced, the side flap portion fixing portion can continuously fix the absorbent article to the clothing, and therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to be peeled off from the clothing, and the wearing feeling of the absorbent article can be continuously excellent.
The individual package of the absorbent article of the present disclosure is described in detail below.

The absorbent main body 5 includes, in order in the thickness direction T, a liquid-permeable sheet 7, a second sheet 9, an absorbent body 11, a liquid-impermeable sheet 13, and a fixing portion 15 for fixing the sanitary napkin 3 to a garment. In addition, since the second sheet 9 and the absorbent body 11 have the same shape in the thickness direction T, they may be shown together in the drawings. The absorbent body 11 also contains pulp fibers (not shown).
The pair of side flap portions 17 includes, in order in the thickness direction T, a liquid-permeable side sheet 19, a liquid-impermeable side sheet 21, and a side flap portion fixing portion 23 for fixing the pair of side flap portions 17 to the garment.
The liquid-permeable sheet 7 and the liquid-permeable side sheet 19 are connected by embossed portions 101 extending in the longitudinal direction L. The liquid-impermeable sheet 13 and the liquid-impermeable side sheet 21 are integrally formed.
The individual package 1 is manufactured as follows: (i) The sanitary napkin 3 is arranged on the packing sheet 25 having airtightness and having a peeling property on the inner surface so that the fixing portion 15 is in contact with the inner surface of the packing sheet 25; (ii) The sanitary napkin 3 and the packaging sheet 25 are folded along two folding axes F 1 And a folding axis F 2 Folding for the base point; then, (iii) the folded packaging sheet 25 is sealed along the longitudinal direction L at both side portions in the longitudinal direction L (both end portions in the width direction W) to form a pair of sealing regions 105. Each of the pair of seal regions 105 includes a plurality of seal portions 107 arranged intermittently in the longitudinal direction L and the width direction W.
Further, the flap fixing portion 23 is fixed to the release sheet 103.
The packaging sheet 25 has a three-layer structure of a1 st welding layer (not shown) constituting the inner surface of the packaging sheet 25, an inner liner layer (not shown), and a 2 nd welding layer (not shown) constituting the outer surface of the packaging sheet 25. The melting point of the inner liner is higher than the melting points of the 1 st and 2 nd welding layers. Further, the packaging sheet 25 has a thickness of 100cc/m 2 Oxygen permeability of/day/atm or less.
The package sheet 25 has a long shape elongated in one direction, and the longitudinal direction of the package sheet 25 coincides with the longitudinal direction L of the sanitary napkin 3. The packaging sheet 25 includes: (i) One end edge 117 in the longitudinal direction of the packaging sheet 25 and the folding axis F having the pull tab 109 for opening the individual package 1 1 Divided 1 st slice 111; (ii) By folding axis F 1 And a folding axis F 2 The divided 2 nd slice 113; and (iii) from the fold axis F 2 And a 3 rd sheet 115 defined by the other end edge 119 in the longitudinal direction of the packaging sheet 25.
The individual package 1 has a pressure-sensitive adhesive portion 121 extending in the width direction W of the sanitary napkin 3 in a portion near one end edge 117 of the surface of the 1 st sheet 111 that contacts the 3 rd sheet 115, in order to suppress volatilization of the cooling composition 31 described later. The adhesive portion 121 is continuously disposed across the pair of seal regions 105, and fixes the 1 st sheet 111 to the 3 rd sheet 115, thereby suppressing volatilization of the cooling composition 31.
The sanitary napkin 3 has: a circular seal portion 123 for sealing the liquid-permeable sheet 7 and the liquid-impermeable sheet 13 and also sealing the liquid-permeable side sheet 19 and the liquid-impermeable side sheet 21; through holes 125 formed from the liquid-permeable sheet 7 to the absorbent body 11; and an opening portion 127 formed in the liquid-permeable sheet 7.
As shown in FIG. 5, in the absorbent body 5, the cooling composition 31 has a weight per unit area of 10g/m 2 The above-described mode is applied to the application region 33 of the liquid-permeable sheet 7 on the absorbent body 11 side. The application region 33 is arranged to be shorter than the second sheet 9 and the absorbent body 11 in the longitudinal direction L and the width direction W in a range overlapping with the second sheet 9 and the absorbent body 11 in the thickness direction T. Thus, the liquid refreshing composition 31 is less likely to extend beyond the pulp fiber-containing absorbent body 11 and the liquid-impermeable sheet 13 and reach the anchor sections 15, and the anchor sections 15 are less likely to be plasticized, during storage and use of the sanitary napkin 3.
The cooling composition 31 contains a low-attenuation cooling agent having an attenuation rate (temperature: 40 ℃, relative humidity: 70% rh, time: 8 hours) of 20% by mass or more and 60% by mass or less in a proportion of 50% or more, and contains a high-attenuation cooling agent having an attenuation rate (temperature: 40 ℃, relative humidity: 70% rh, time: 8 hours) of more than 60% by mass in a proportion of 20% or less. This makes it possible to keep the wearer cool for a long time from the initial wearing time even when the sanitary napkin 3 is worn for a long time. Further, even when the sanitary napkin 3 is worn for a long time, the fixing portion 15 is not easily peeled off from the wearing clothes, and the wearing feeling of the sanitary napkin 3 can be continued to be excellent.
Further, the cooling composition 31 contains a perfume at a ratio of 30% or less and does not contain a lubricant. Thus, even when the sanitary napkin 3 is worn for a long time, the fixing portion 15 is less likely to peel off from the wearing clothes, and the wearing feeling of the sanitary napkin 3 can be maintained excellent.
Furthermore, cooling composition 31 had a viscosity of 300 mPas (30 ℃ C.). Thus, the refreshing composition 31 is less likely to move to the fixing portion 15 while remaining in a liquid state, and the fixing portion 15 is less likely to be plasticized by the refreshing composition 31 in a liquid state.
The absorbent body 5 includes a liquid-permeable sheet 7, a second sheet 9, and an absorbent body 11 compressedAnd a compression part 41. The compression portion 41 includes an abutment region R intermittently surrounding the discharge opening E And an outer compressing portion 49 intermittently surrounding the inner compressing portion 43.
The inner compression part 43 is divided into a region disposed in the drain port contact region R E An inner longitudinal-direction-extending compression portion 45a disposed on the right side in the width direction W and extending in the longitudinal direction L, and a drain contact region R E And an inner longitudinally extending and compressing portion 45b extending in the longitudinal direction L on the left side in the width direction W, and arranged in the drain port contact region R E An inner widthwise extending and compressing portion 47a extending in the widthwise direction W forward in the longitudinal direction L, and a drain contact region R disposed in the drain contact region R E And an inner widthwise extending compressed portion 47b extending rearward in the longitudinal direction L and in the widthwise direction W.
The inner longitudinally extended compression portion 45a and the inner longitudinally extended compression portion 45b include a high compression portion 51 having a relatively high degree of compression and a low compression portion 53 having a relatively low degree of compression, respectively. The high compression portions 51 have a circular shape and are arranged between the low compression portions 53 in a dispersed manner. This makes the sanitary napkin 3 easily adhere to the wearer's skin along the line of the wearer's body.
The inner longitudinally extending and compressing portion 45a and the inner longitudinally extending and compressing portion 45b hold the cooling composition 31, respectively. Thus, when the inner longitudinally extended compressed portion 45a and the inner longitudinally extended compressed portion 45b function as folding starting points when the sanitary napkin 3 is worn, the wearer can easily continue to feel cool.
The inner width direction extending compressed portion 47a and the inner width direction extending compressed portion 47b include a high compressed portion 55 having a relatively high degree of compression and a low compressed portion 57 having a relatively low degree of compression, respectively. The high compression portions 55 have a circular shape and are arranged between the low compression portions 57 in a dispersed manner. This makes the sanitary napkin 3 more likely to be in close contact with the wearer's skin along the line of the wearer's body.
The inside widthwise extended compressed portion 47a and the inside widthwise extended compressed portion 47b hold the cooling composition 31, respectively. Thus, when the inner laterally extending compressed parts 47a and the inner laterally extending compressed parts 47b function as folding starting points when the sanitary napkin 3 is worn, the wearer can easily continue to feel cool.
The area ratio of the high compressed portions 55 of the inner widthwise extending compressed portion 47a and the inner widthwise extending compressed portion 47b (the area of the high compressed portion 55/the area of the inner widthwise extending compressed portion 47a or the area of the high compressed portion 55/the area of the inner widthwise extending compressed portion 47 b) is higher than the area ratio of the high compressed portions 51 of the inner lengthwise extending compressed portion 45a and the inner lengthwise extending compressed portion 45b (the area of the high compressed portion 51/the area of the inner lengthwise extending compressed portion 45a or the area of the high compressed portion 51/the area of the inner lengthwise extending compressed portion 45 b). Thus, when the sanitary napkin 3 is used, the excretory opening contact region R E The liquid-permeable sheet 7 and the absorbent body 11 are less likely to peel off at both ends in the longitudinal direction L of the sanitary napkin, and the sanitary napkin 3 is less likely to twist.
In embodiment 1, the liquid-impermeable sheet 13 is a sheet having no air-permeable holes. Thus, even when the liquid-impermeable sheet 13 is deformed while the sanitary napkin 3 is worn, the refreshing composition 31 does not easily reach the fixing portion 15 through the liquid-impermeable sheet 13, and the fixing portion 15 is not easily plasticized.
Fig. 7 to 9 are views for explaining the individual package 1 of the sanitary napkin 3 according to another embodiment (hereinafter referred to as "embodiment 2") of the present disclosure. Specifically, fig. 7 and 8 are a front view and a rear view of the sanitary napkin 3 in the unfolded state, respectively. Fig. 9 is a view for explaining the application region 33 of the cooling composition 31, and is a view of the liquid-permeable sheet 7 and the liquid-permeable side sheet 19 on the side closer to the absorbent body 11.
The sanitary napkin 3 according to embodiment 2 is similar to the sanitary napkin 3 according to embodiment 1 in many parts, and therefore, different parts will be mainly described.
As shown in FIG. 9, in the absorbent body 5, the cooling composition 31 has a weight per unit area of 10g/m 2 The above method is applied to the application region 33 of the liquid-permeable sheet 7 on the absorbent body 11 side. Coating zone 33 shapeWithin a range overlapping with the second sheet 9 and the absorbent body 11 in the thickness direction T. In addition, in the pair of wing portions 17, the cooling composition 31 has a weight per unit area of 5g/m 2 The liquid-permeable side sheet 19 is applied to the surface thereof on the absorbent body 11 side.
The weight per unit area of the absorbent body adhesive (not shown) that bonds the liquid-permeable sheet 7 and the liquid-impermeable sheet 13 of the absorbent body 5 is larger than the weight per unit area of the side-flap adhesive (not shown) that bonds the liquid-permeable side sheet 19 and the liquid-impermeable side sheet 21 of each of the pair of side flap portions 17. Thus, even when the sanitary napkin 3 is worn for a long time, the absorbent main body 5, specifically, the liquid-permeable sheet 7 and the liquid-impermeable sheet 13 are less likely to peel off from the wearing clothes, and the wearing feeling of the sanitary napkin 3 can be maintained excellent.
The fastening portions 15 of the absorbent body 5 have a weight per unit area smaller than the weight per unit area of the wing fastening portions 23 of the pair of wings 17. Thus, even when the fixing portion 15 is plasticized and the adhesion of the fixing portion 15 is lowered, the flap portion fixing portion 23 can continuously fix the sanitary napkin 3 to the garment.
In the individual package of the present disclosure, from the viewpoint of suppressing volatilization of the cooling composition, the packaging sheet is preferably air-tight in the thickness direction of the packaging sheet. From the viewpoint of the airtightness, the packaging sheet preferably has a thickness of 100cc/m at 23 ℃ 2 Oxygen permeability in the thickness direction of/day/atm or less, more preferably 60cc/m 2 A value of not more than day/atm, more preferably 40cc/m 2 A value of not more than day/atm, more preferably 30cc/m 2 And/day/atm or less.
The above oxygen permeability was measured according to the coulometric method under the conditions of 23 ℃ at 0% RH.
The packaging sheet may have any layer structure, for example, a three-layer structure (1 st fusion layer, inner liner, and 2 nd fusion layer) shown in embodiment 1, a two-layer structure (fusion layer and inner liner), and the like, and preferably includes a fusion layer and an inner liner having a melting point higher than that of the fusion layer.
The inner liner preferably has a melting point higher than the melting point of the fusion layer, and the inner liner preferably has a melting point higher than the melting point of the fusion layer by 30 to 90 ℃, more preferably by 40 to 80 ℃, and further preferably by 45 to 75 ℃. By doing so, the inner liner layers of the two sheets adjacent to each other of the packaging sheet are prevented from being welded to each other, and the welded layers of the two sheets adjacent to each other are welded to each other, whereby the independent packaging body of the present disclosure is excellent in opening performance.
In the individual package of the present disclosure, the inner liner preferably has a softening point higher than the softening point of the welding layer, and the inner liner preferably has a softening point higher than the softening point of the welding layer by 10 to 50 ℃, and more preferably 20 to 40 ℃. By doing so, the inner liner layers of the two sheets of the packaging sheet are prevented from being welded to each other, and the welded layers of the two sheets adjacent to each other of the packaging sheet are welded to each other, so that the independent packaging body of the present disclosure is excellent in opening performance.
In the packaging sheet, as a material of the inner liner layer, materials known in the art can be used without limitation as long as the material can maintain airtightness in the thickness direction, and examples thereof include ethylene-vinyl alcohol copolymers, vinylidene chloride polymers such as vinylidene chloride methyl acrylate copolymers, polyvinyl alcohol, nylon such as nylon 6, and materials obtained by vapor deposition of aluminum oxide, silica, and the like on an aluminum foil or a base film (polyethylene terephthalate or the like).
In the above-described packaging sheet, a material for the fusion-bonded layer can be a material known in the art without limitation, and examples thereof include polyolefin polymers such as polyethylene and polypropylene.
In the individual package of the present disclosure, the pair of sealing regions is not particularly limited as long as the volatilization of the cooling composition can be suppressed, and includes a form known in the art. The pair of seal regions may be formed by welding the weld layers of two sheets adjacent to each other as in embodiment 1 and embodiment 2, for example, or may be formed by bonding two sheets adjacent to each other with an adhesive or the like.
In the individual package of the present disclosure, the absorbent article may be folded or unfolded.
In the individual package of the present disclosure, the mode of individual packaging is not particularly limited as long as the absorbent article is individually packaged in the packaging sheet.
An absorbent article of the present disclosure includes an absorbent main body including a liquid-permeable sheet, an absorbent body, a liquid-impermeable sheet, and a fixing portion for fixing the absorbent article to a wearing garment. The absorbent article may include, as desired components, an auxiliary sheet (for example, a diffusion sheet such as a second sheet) disposed between the liquid-permeable sheet and the absorber, an auxiliary sheet (for example, a diffusion sheet) disposed between the absorber and the liquid-impermeable sheet, and the like. Further, the absorber may include an absorbent core, a core cladding, and the like.
In the individual package of the present disclosure, the cooling composition may be packaged in a package sheet, and the cooling composition may be disposed on the inner surfaces of the absorbent article (e.g., the absorbent main body and the desired pair of side flap portions) and the package sheet.
In the individual package of the present disclosure, in the case where the absorbent body holds the cooling composition, the cooling composition of the absorbent body can be disposed at any position in the thickness direction of the absorbent article in the expanded state. The refreshing composition may be disposed, for example, on the liquid-permeable sheet side of the liquid-impermeable sheet, inside the liquid-impermeable sheet, or on the fixed portion side of the liquid-impermeable sheet, and the refreshing composition is preferably disposed on the liquid-permeable sheet side of the liquid-impermeable sheet. This is because the liquid cooling composition does not easily plasticize the fixing portion.
In addition, in the present disclosure, the unfolded state of the absorbent article is not premised on folding the absorbent article in an individual package.
When the cooling composition is disposed on the liquid-permeable sheet side of the liquid-impermeable sheet, the cooling composition can be disposed on, for example, the liquid-permeable sheet (skin side or non-skin side), the absorbent body (skin side or non-skin side), or a desired auxiliary sheet (skin side or non-skin side).
The region of the absorbent body to which the cooling composition is applied can be disposed in the excretory opening contact region, the absorbent body overlapping region that overlaps the absorbent body, and the like in the planar direction of the absorbent article in the expanded state of the absorbent article.
In the case where the application region is formed in both of the absorbent body overlapping region overlapping with the absorbent body and the non-absorbent body overlapping region not overlapping with the absorbent body, the cooling composition in the absorbent body overlapping region preferably has a higher weight per unit area than the cooling composition in the non-absorbent body overlapping region. Thus, the refreshing composition (mainly liquid refreshing composition) disposed in the non-absorbent-body overlapping region is less likely to contact with an adhesive (hot melt adhesive or the like) joining the liquid-permeable sheet and the liquid-impermeable sheet to plasticize the adhesive, and is less likely to move to the fixing portion and plasticize the fixing portion.
The cooling composition contains a low-attenuation cooling agent having an attenuation rate (temperature: 40 ℃, relative humidity: 70% RH, time: 8 hours) of 20 to 60 mass%, preferably 55% or more, and more preferably 60% or more, in a proportion of 50% or more. Thus, when the individual package is stored, the low-attenuation refreshing agent is less likely to migrate to the fixing portion and plasticize the fixing portion, and the wearer can continue to feel cool even when the absorbent article is worn for a long time.
The upper limit of the proportion of the low-attenuation cooling agent in the cooling composition is 100%.
The cooling composition may or may not contain a high-attenuating cooling agent having a decay rate (temperature: 40 ℃, relative humidity: 70% RH, time: 8 hours) of more than 60% by mass. When the cooling composition contains a high-attenuating cooling agent, the cooling composition preferably contains the high-attenuating cooling agent in a proportion of 20% or less, more preferably 15% or less, and still more preferably 10% or less. In addition, when the cooling composition contains a high-attenuation cooling agent, the cooling composition preferably contains the high-attenuation cooling agent in a proportion of 1% or more, more preferably 3% or more, and even more preferably 5% or more. This makes the absorbent article more likely to cause the wearer to feel cool from the initial stage of wearing.
In the present specification, the attenuation ratio (% by mass) (temperature: 40 ℃, relative humidity: 70% RH, time: 8 hours) is measured as follows.
(1) A plurality of samples (initial samples) of the individual packages of the absorbent article to be measured are prepared.

(3) Five initial samples from which the packaging sheet was peeled were placed to fill a predetermined amount: v (g) of the solvent, and the container was stirred for 5 minutes to precipitate the cooling agent in the five initial samples into the solvent. Analyzing the above solvents using a gas chromatograph-mass spectrometer, measuring the initial area of at least the peak of the cooling agent (low-attenuating cooling agent or high-attenuating cooling agent) in the cooling composition: a. The c0 (count)。
(4) Five samples of elapsed time from which the packaging sheet was peeled were placed to fill a predetermined amount: and v (g) in a container, and stirring the container for 5 minutes to precipitate at least the cooling agent in the five samples with time into the solvent. The above solvents were analyzed using a gas chromatograph-mass spectrometer, and the area over time of the peak of the cooling agent (low-attenuating cooling agent or high-attenuating cooling agent) in the cooling composition was measured: a. The c1 (count)。
As the predetermined amount of the above solvent: v (g) is, for example, 10 times the mass of five initial samples.
(5) Using the following equation:
attenuation rate (mass%) =100 × (a) c0 -A c1 )/A c0
The decay rate (% by mass) was calculated.
The solvent is not particularly limited as long as it can precipitate a cooling agent (low-attenuation cooling agent or high-attenuation cooling agent), and for example, ethyl acetate can be cited.
The gas chromatograph-mass spectrometer may be a GCMS-QP2010 Plus manufactured by Shimadzu corporation.
In addition, the peak value of a cooling agent (low-attenuation cooling agent or high-attenuation cooling agent) of the gas chromatography-mass spectrometer can be determined from the retention time of the peak value and the mass spectrum. Further, the peak value of the cooling agent can be determined as follows: the structure of a cooling agent in a cooling composition is determined by a method known in the art (NMR and the like), and a compound having the same structure as the cooling agent is used as a standard sample, measured by a gas chromatograph, and compared with the retention time of the standard sample.
Further, in the case where different cooling compositions are arranged in the absorbent main body and the pair of side wing portions, the absorbent main body and the pair of side wing portions can be separately measured while being separated.
The cooling compositions described above may or may not include a fragrance. When the cooling composition contains a flavor, the cooling composition preferably contains the flavor at a ratio of 30% or less, more preferably 25% or less, and still more preferably 20% or less. When the cooling composition contains a flavor, the cooling composition preferably contains the flavor at a ratio of 1% or more, more preferably 3% or more, and still more preferably 5% or more. This makes it possible to impart a fragrance to the wearer even when the absorbent article is worn for a long time, and the fixing portion is not easily peeled off from the clothing, so that the absorbent article can continue to have an excellent wearing feeling.
The cooling agent may or may not contain a lubricant. When the cooling composition contains a lubricant, the cooling composition preferably contains the lubricant at a ratio of 30% or less, more preferably 20% or less, and still more preferably 10% or less. When the cooling composition contains a lubricant, the cooling composition preferably contains the lubricant in a proportion of 1% or more, more preferably 3% or more, and still more preferably 5% or more. This makes it difficult for the lubricant to plasticize the fastening portion, and the fastening portion is not easily peeled off from the clothing even when the absorbent article is worn for a long time.
In the present specification, the proportions of coolants (low-attenuating coolants and desired high-attenuating coolants), desired flavors, and desired lubricants (hereinafter simply referred to as "ingredients") in the cooling composition are measured as described below using an area percentage method using a gas chromatograph.

Examples of the animal wax include spermaceti wax, beeswax, and lanolin.
Examples of the vegetable oil include drying oils such as grape seed oil, safflower oil, and soybean oil, semi-drying oils such as sesame oil, corn oil, cottonseed oil, rapeseed oil, and sunflower oil, avocado oil, sweet almond oil, olive oil, camellia oil, almond oil, castor oil, and peanut oil, and preferably a semi-drying oil or a non-drying oil that changes little with time.
Examples of the vegetable fat include cacao butter, palm oil, palm kernel oil, macadamia nut oil, wood wax, and coconut oil.
Examples of the vegetable wax include carnauba wax, candelilla wax, jojoba oil, and the like.
Examples of the petroleum hydrocarbon include dialkyl carbonates having 14 to 15 carbon atoms, vaseline, paraffin, squalane, spermaceti, ceresin, sericin, and microcrystalline wax.
Examples of the fatty acid ester include glycerin fatty acid esters. The fatty acid ester is generally used in cosmetics and is highly safe. The glycerin fatty acid ester may be any of monoglycerides, diglycerides, and triglycerides. The glycerin fatty acid ester has a fatty acid having 2 to 35 carbon atoms, preferably 8 to 22 carbon atoms. When the number of carbon atoms is 8 or more, it is liquid at room temperature (25 ℃ C.), and handling is easy. When the carbon number is 8 to 22, the melting point is 60 to 70 ℃ or lower, and when the absorbent article is worn on the skin-contacting surface, the carbon number tends to be transferred to the skin by body temperature during wearing.
As the organic acid ester, triethyl citrate can be cited, for example.
The cooling composition may have any viscosity, and for example, has a viscosity of preferably 50mPa · s or more, more preferably 100mPa · s or more, further preferably 200mPa · s or more, further preferably 300mPa · s or more, and further preferably 400mPa · s or more at 30 ℃. The cooling composition has a viscosity of preferably 1 to 500mPa · s or less, more preferably 1000mPa · s or less, even more preferably 800mPa · s or less, even more preferably 700mPa · s or less, and even more preferably 600mPa · s or less, at 30 ℃. Thus, the cooling composition is less likely to move to the fixed portion while remaining in a liquid state, and the fixed portion is less likely to be plasticized by the cooling composition in a liquid state.
In the present specification, the above viscosity is measured as follows.

In the individual package of the present disclosure, in the case where the cooling composition is disposed as a mixture, the absorbent main body may be preferably 1.0g/m 2 The above weight per unit area has a cooling composition, more preferably 3.0g/m 2 Above, more preferably 5.0g/m 2 Above, more preferably 7.0g/m 2 The above. Further, the absorbent main body may preferably be 30.0g/m 2 The following weight per unit area has a cooling composition, more preferablyIs selected to be 20.0g/m 2 Hereinafter, it is more preferably 16.0g/m 2 Hereinafter, more preferably 14.0g/m 2 The following. By doing so, in the above-described individual package, not only in the case where the cooling composition is in the same amount as usual, but also in the case where it is present in an amount larger than usual, the cooling composition does not easily plasticize the fixed portion.
In the individual packages of the present disclosure, in the case where the cooling composition is provided as a non-mixture, for example, separately for each component, the absorbent body can have the cooling composition in an amount of preferably 0.001 g/piece or more, more preferably 0.003 g/piece or more, further preferably 0.005 g/piece or more, and still further preferably 0.007 g/piece or more per individual package. In addition, the absorbent main body may have the cooling composition in an amount of preferably 1.00 g/piece or less, more preferably 0.50 g/piece or less, further preferably 0.10 g/piece or less, and further preferably 0.05 g/piece or less, per one individual package. By doing so, in the above-described individual package, not only in the case where the cooling composition is in the same amount as usual, but also in the case where it is present in an amount larger than usual, the cooling composition does not easily plasticize the fixed portion.
In addition, the above range can be satisfied also in the case where the cooling composition is disposed as a mixture.
Further, in the individual package of the present disclosure, a sample of an arbitrary area is cut from the absorbent article, and the mass of the sample is measured: m is 0 (g) And area: s (m) 2 ) The cooling composition was removed from the above sample using a solvent, and the mass of the sample from which the cooling composition was removed was measured: m is 1 (g) The following equation can be used:
BS(g/m 2 )＝(m 0 -m 1 )/S
to calculate the weight per unit area of the cooling composition: BS (g/m) 2 )。
In the individual package of the present disclosure, the absorbent article may have an excretion portion contact region.
In the individual package of the present disclosure, the absorbent article may include a pair of longitudinally extending compressed portions which are formed by compressing the liquid-permeable sheet and the absorbent body, are disposed at both widthwise ends of the excretory opening contact region, and extend in the longitudinal direction. The pair of longitudinally extending compressed parts can hold the cooling composition. Thus, even when the absorbent article is worn for a long period of time, the cooling composition disposed on each of the pair of longitudinally extending compression portions is kept in contact with the skin of the wearer, and the wearer can easily feel cooling.
Further, the pair of longitudinally extending compression portions may include a high compression portion having a relatively high degree of compression and a low compression portion having a relatively low degree of compression, respectively. Thus, the absorbent article is likely to be in close contact with the skin of the wearer along the lines of the wearer's body, and the wearer is likely to continue to feel cool.
In the individual package of the present disclosure, the absorbent main body may include a pair of widthwise extending and compressing portions which are formed by compressing the liquid-permeable sheet and the absorbent body, and are disposed at both ends in the longitudinal direction of the excretion portion contact region and extend in the widthwise direction.
Further, the pair of widthwise-extending compression portions may include a high compression portion having a relatively high degree of compression and a low compression portion having a relatively low degree of compression, respectively. This makes the absorbent article easy to adhere to the skin of the wearer along the lines of the wearer's body, and makes the wearer feel cool.
In the individual package of the present disclosure, when the absorbent main body includes the pair of longitudinally extending compressed parts (including the high compressed part and the low compressed part) and the pair of laterally extending compressed parts (including the high compressed part and the low compressed part), it is preferable that an area ratio of the high compressed part of each of the pair of laterally extending compressed parts is higher than an area ratio of the high compressed part of each of the pair of longitudinally extending compressed parts. Thus, when the absorbent article is used, the liquid-permeable sheet and the absorbent body are less likely to be peeled off at both ends in the longitudinal direction of the excretory opening contact region, and the absorbent article is less likely to be twisted.
The area ratio can be calculated by dividing the total area of the high compression portions by the area of each of the pair of width direction extension compression portions, and can be calculated by dividing the total area of the high compression portions by the area of each of the pair of length direction extension compression portions.
The pair of longitudinally extending and compressing portions and the pair of widthwise extending and compressing portions may be separated from each other or may be continuous with each other.
In the individual package of the present disclosure, the liquid-permeable sheet, the absorbent body, the liquid-impermeable sheet and the fixing portion, and the desired auxiliary sheet can be used without particular limitation as the raw materials used in the technical field.
The liquid-impermeable sheet may be a breathable sheet, for example, a sheet having breathable holes, or a non-breathable sheet, for example, a sheet having non-breathable holes. The liquid-impermeable sheet is preferably a sheet having no air permeability. Thus, even when the liquid-impermeable sheet is deformed during wearing, the refreshing composition does not easily reach the fixing portion through the liquid-impermeable sheet, and the fixing portion is not easily plasticized.
The absorbent article of the present disclosure may further include a pair of side wing portions disposed on both side portions in the longitudinal direction of the absorbent main body (both end portions in the width direction of the absorbent main body) for fixing the absorbent article to a wearer's clothing.
The pair of side wing portions can include a liquid-permeable side sheet, a liquid-impermeable side sheet, and a side wing portion fixing portion for fixing the pair of side wing portions to the garment, respectively, and may also include an auxiliary side sheet between the liquid-permeable side sheet and the liquid-impermeable side sheet.
The liquid-permeable side sheet, the liquid-impermeable side sheet, and the side-panel fixing portion may be formed of the same material as the liquid-permeable sheet, the liquid-impermeable sheet, and the fixing portion of the absorbent main body, respectively. The liquid-permeable side sheet may be integral with the liquid-permeable sheet or may be separate from the liquid-permeable sheet. The liquid-impermeable side sheet may be integrated with the liquid-impermeable sheet or may be separate.
The pair of side wings can each include a cooling composition as described above. The cooling composition of each of the pair of side flap portions may include the cooling composition, for example, disposed on the liquid-permeable side sheet (skin-side surface or non-skin-side surface), a desired auxiliary side sheet (skin-side surface or non-skin-side surface), or the like, at a position closer to the liquid-permeable side sheet than the liquid-impermeable side sheet in the thickness direction of the absorbent article in the unfolded state of the absorbent article.
The cooling composition of each of the pair of side flap portions can be disposed at an arbitrary position in the planar direction of the absorbent article in the unfolded state of the absorbent article.
In the individual package of the present disclosure, in the case where the absorbent article includes the pair of side wing portions and the pair of side wing portions include the cooling composition, it is preferable that the absorbent main body has a weight per unit area of the cooling composition larger than the weight per unit area of the cooling composition of the pair of side wing portions, and the absorbent main body adhesive bonding the liquid-permeable sheet and the liquid-impermeable sheet of the absorbent main body has a weight per unit area larger than the weight per unit area of the side wing portion adhesive bonding the liquid-permeable side sheet and the liquid-impermeable side sheet of the pair of side wing portions. Thus, even when the absorbent article is worn for a long time, the absorbent body, specifically, the liquid-permeable sheet and the liquid-impermeable sheet are not easily peeled off from the worn garment, and the wearing feeling of the absorbent article can be continued to be excellent.
In the individual package of the present disclosure, when the absorbent article includes the pair of side wing portions and the pair of side wing portions include the cooling composition, the cooling composition preferably has a weight per unit area greater than that of the cooling composition included in each of the pair of side wing portions and the fixing portion preferably has a weight per unit area less than that of the fixing portion of the side wing portions. In this way, in the absorbent article, even when the fixing portion is plasticized and the adhesion force thereof is reduced, the side flap portion fixing portion can continuously fix the absorbent article to the clothing, and therefore, even when the absorbent article is worn for a long time, the fixing portion is less likely to be peeled off from the clothing, and the wearing feeling of the absorbent article can be continuously excellent.
The cooling composition included in each of the pair of wing portions can be configured by separately applying the same or different cooling composition as that included in the absorbent main body to each of the pair of wing portions, relative to the cooling composition included in the absorbent main body. Further, the cooling composition included in each of the pair of wing portions can be disposed by transferring the cooling composition included in the absorbent main body to each of the pair of wing portions.
In the individual package of the present disclosure, the cooling composition may be disposed as a mixture in the absorbent main body, the pair of side flap portions, or the like, or may be disposed separately for each component.
The absorbent article in the individual package of the present disclosure is not particularly limited, and examples thereof include sanitary napkins, sanitary shorts, pants-type sanitary napkins, pantiliners, disposable diapers, and light incontinence pads.
