[Figure 15] Figures 15A and 15B are explanatory diagrams of the packaging 80 of the second embodiment. [Modes for carrying out the invention]

[0009] The following matters become clear from this specification and the accompanying drawings: (Aspect 1) A package in which an absorbent article containing an absorbent material is packaged in a packaging material, wherein the packaging material has a nonwoven fabric layer and a film layer, and when unfolded, the packaging material has one side and the other side in the longitudinal direction, and is housed in the package in a state where the packaging material is folded along a fold in the transverse direction such that the nonwoven fabric layer becomes the outermost layer of the package, the absorbent article has a skin-side sheet positioned closer to the skin than the absorbent material, and has a cooling agent in at least the nonwoven fabric layer and the skin-side sheet, and when the package is removed from the package and unfolded, the weight of the cooling agent present per unit area of ​​the skin-side sheet of the unfolded absorbent article is greater than the weight of the cooling agent present per unit area of ​​the nonwoven fabric layer in the one side of the packaging material.

[0010] According to Aspect 1, when the absorbent article is taken out of the package, the cooling agent provided in the non-woven fabric layer (the outermost layer) on one side of the packaging material makes it easy for the user to recall a refreshing feeling from before opening the package (before starting to use the absorbent article). And when wearing the absorbent article after opening and unfolding the package (after starting to use the absorbent article), since more cooling agents are provided on the skin-side sheet of the absorbent article, it is easy for the user to actually feel the refreshing feeling.

[0011] (Aspect 2) A package in which an absorbent article including an absorber is packaged with a packaging material, the packaging material having a non-woven fabric layer and a film layer, the packaging material having one side portion and the other side portion in the longitudinal direction in the unfolded state, and the packaging material being folded at a folding portion along the lateral direction so that the non-woven fabric layer becomes the outermost layer of the package and is housed in the package, in the folded state of the packaging material, having an opposing region facing the one side portion, and the film layer of the one side portion having a joint portion joined to the non-woven fabric layer of the opposing region by an adhesive, and when the package is taken out of the package and made into an unfolded state, the non-woven fabric layer in the one side portion and the non-woven fabric layer in the region on the other side of the joint portion in the opposing region having a portion where a cooling agent is present. A package characterized by this.

[0012] According to Aspect 2, when the absorbent article is taken out of the package, the cooling agent provided in the non-woven fabric layer (the outermost layer) on one side of the packaging material makes it easy for the user to recall a refreshing feeling from before opening the package (before starting to use the absorbent article). And when wearing the absorbent article after opening and unfolding the package (after starting to use the absorbent article), since the cooling agent is provided in the non-woven fabric layer of the opposing region exposed when the packaging material is opened, it is easier for the user to recall the refreshing feeling.

[0013] (Aspect 3) The packaging according to embodiment 2, wherein the weight of the cooling agent present per unit area of ​​the nonwoven fabric layer in the region of the opposing region on the other side of the joint is greater than the weight of the cooling agent present per unit area of ​​the nonwoven fabric layer in the one side portion.

[0014] According to Embodiment 3, by providing the cooling agent on the nonwoven fabric located in the outermost layer of the packaging (outer cooling agent area), it is possible to easily evoke a feeling of coolness in the user even before opening the packaging (before starting to use the absorbent article). Furthermore, when the packaging is opened and the opposing area is exposed (after starting to use the absorbent article), since more cooling agent is provided on the nonwoven fabric of the opposing area (inner cooling agent area), a greater feeling of coolness can be generated in the user.

[0015] (Aspect 4) The packaging material has the nonwoven fabric layer on one side in the thickness direction, the film layer adjacent to the other side of the nonwoven fabric layer, and the other side of the film layer has a portion where the cooling agent is present, according to embodiment 2 or 3.

[0016] According to Embodiment 4, the presence of a cooling agent on the other side of the film layer that is not easily exposed to the outside when the packaging is folded allows the cooling agent on the other side of the film layer to easily diffuse into the atmosphere when the packaging is opened, making it easier to create a cooling sensation in the user.

[0017] (Aspect 5) The packaging according to any one of embodiments 1 to 4, wherein the cooling agent is menthol or a substance with a molecular weight greater than menthol.

[0018] According to Embodiment 5, by using menthol, which is highly volatile at room temperature and pressure, as a cooling agent, the volatile cooling agent can easily diffuse into the atmosphere when the user opens the packaging, making it easier for the user to experience a cooling sensation. Furthermore, menthol glycerin acetal (MGA) and menthyl lactate, which have a larger molecular weight than menthol, are less volatile than menthol, making it easier for the cooling agent in packaging materials and absorbent articles to be maintained. Therefore, it is possible to make it easier for the user to experience a cooling sensation before and after starting to use the absorbent article.

[0019] (Aspect 6) The packaging according to any one of embodiments 1 to 5, wherein the nonwoven fabric layer contains long fibers and has multiple high-density areas where the density is higher than that of the surrounding area.

[0020] According to embodiment 6, since irregularities are easily formed on the surface of the nonwoven fabric in the high-density areas, the cooling agent is more easily retained compared to when the surface is smooth. In addition, because the nonwoven fabric contains long fibers, the cooling agent is more easily trapped and retained between the entangled long fibers. Therefore, when a user holds the package, it is easier to recognize the cooling agent held in the high-density areas (irregularities) of the outermost nonwoven fabric layer. Furthermore, if high-density areas (irregularities) are formed on the surface of the outermost nonwoven fabric layer of the package, the package becomes easier to hold and less slippery, making it easier to perform operations such as opening the package.

[0021] (Aspect 7) The packaging according to any one of embodiments 1 to 6, wherein, when the packaging material is folded, it has a facing region opposite to the one side, the film layer of the one side has a joint portion joined to the nonwoven fabric layer of the facing region by adhesive along the transverse direction, and the one side has an unjoint portion outside the joint portion where the film layer of the one side and the nonwoven fabric layer of the facing region are not joined, and the unjoint portion has a plurality of high-density portions which are denser than the surrounding area.

[0022] According to Embodiment 7, the non-jointed portion having a high-density portion makes it easier for the cooling agent to be retained in the high-density portion (irregularities) formed on the surface of the packaging material, making it easier to create a cooling sensation in the user when opening the package. In addition, the nonwoven fabric layer of the packaging material becomes easier to fold using the irregularities formed by the high-density portion as a starting point, making it easier to peel back and pinch the non-jointed portion when opening the package.

[0023] (Pattern 8) The packaging material has the nonwoven fabric layer on one side in the thickness direction, the film layer adjacent to the other side of the nonwoven fabric layer, and in the thickness direction, at least a portion of the fibers contained in the nonwoven fabric layer are located on the side other than the outermost surface of the film layer, according to any one of embodiments 1 to 7.

[0024] According to embodiment 8, because some of the fibers of the nonwoven fabric layer are embedded on the film layer side of the interface between the nonwoven fabric layer and the film layer, the film layer becomes more easily deformable, starting from the area around the embedded fibers, making it easier to conform to the user's hand. Furthermore, the increased deformability of the film layer makes it easier to open the package.

[0025] (Aspect 9) The packaging according to any one of embodiments 1 to 8, wherein the thickness of the film layer in the portion where the fibers contained in the nonwoven fabric layer are located on the side other than the outermost surface of the film layer is thinner than the thickness of the film layer in the portion where the fibers contained in the nonwoven fabric layer are located on the side other than the outermost surface of the film layer.

[0026] According to embodiment 9, in the portion where the fibers are embedded in the film layer, the film layer is thinner, which makes it easier for a starting point for bending deformation of the film layer to form in that thinned portion, making it easier for the user to hold and making it easier to open the package.

[0027] (Aspect 10) The packaging according to any one of embodiments 1 to 9, wherein the film layer has, in the thickness direction, a welded layer located on the outside and an intermediate layer located inside the welded layer, the intermediate layer having lower oxygen permeability and higher rigidity than the welded layer, and the thickness of the intermediate layer in the portion where the fibers contained in the nonwoven fabric layer are located on the side other than the outermost surface of the film layer is thinner than the thickness of the intermediate layer in the portion where the fibers contained in the nonwoven fabric layer are located on the side other than the outermost surface of the film layer.

[0028] According to embodiment 10, in areas where the intermediate layer is thinner, the cooling agent is prevented from leaking out, and a point for bending deformation is more easily formed, making it easier for the user to hold and making it easier to open the package. Furthermore, in areas where the fibers contained in the nonwoven fabric layer are located on one side of the film layer, the intermediate layer is thicker than in other areas, resulting in higher rigidity of the film layer and making the packaging material less prone to deformation. As a result, the shape of the package is less likely to collapse, and the space in which the napkin is contained inside the package is more easily maintained stably.

[0029] (Aspect 11) A packaging body according to any one of embodiments 1 to 10, wherein, when the packaging material is folded, it has a facing region that faces the one side, and the film layer of the one side has a joint that is joined to the nonwoven fabric layer of the facing region along the transverse direction by an adhesive, and the adhesive is impregnated into the nonwoven fabric layer of the facing region.

[0030] According to embodiment 11, gaps are less likely to form in the thickness direction between the film layer on one side and the nonwoven fabric layer in the opposing region, thereby suppressing leakage of the cooling agent. Furthermore, even if the cooling agent tries to escape to the outside through the fibers inside the nonwoven fabric layer, the passage is blocked and reduced in size by the adhesive, making it easier to suppress leakage of the cooling agent.

[0031] (Aspect 12) The packaging according to embodiment 11, wherein the adhesive impregnating the nonwoven fabric layer in the opposing region does not reach the interior of the film layer in the opposing region.

[0032] According to embodiment 12, the film layer on one side of the packaging material and the film layer in the opposing region are not joined by adhesive, and the user can cleanly peel (open) the film layer on one side and the nonwoven fabric layer in the opposing region between the layers with relatively little force. Furthermore, the amount of adhesive is not so large that it impregnates the entire thickness of the nonwoven fabric layer in the opposing region, and the amount of adhesive at the joint is moderately suppressed, so the user can peel the joint with relatively little force.

[0033] (Aspect 13) The packaging according to any one of embodiments 1 to 12, wherein the film layer and the nonwoven fabric layer each have an uneven surface, and the average depth of the unevenness of the film layer is smaller than the average depth of the unevenness of the nonwoven fabric layer.

[0034] According to embodiment 13, if the average depth of the unevenness of the film layer is smaller than the average depth of the unevenness of the nonwoven fabric layer, the gaps between opposing film layers and the gaps between the film layer and the nonwoven fabric layer can be reduced. Therefore, the nonwoven fabric layer improves the feel of the packaging material to the touch, while ensuring sufficient bonding strength at the side joints and making it easier to prevent excessive leakage of the cooling agent from the sides of the packaging.

[0035] (Aspect 14) The packaging material, when folded, has a facing region opposite to the one side, the film layer of the one side has a joint portion joined to the nonwoven fabric layer of the facing region by adhesive along the transverse direction, the nonwoven fabric layer is a nonwoven fabric layer containing long fibers, and has a compressed portion compressed from one side or the other side in the thickness direction, and the joint portion has a portion that overlaps with the compressed portion when viewed in the thickness direction, according to any one of embodiments 1 to 13.

[0036] According to embodiment 14, when the compression part is compressed from the side opposite to the film layer, the bonding area (contact area) between the film layer on one side and the nonwoven fabric layer in the opposing region becomes smaller by the amount of the compression part (recess), making it easier for the user to open the joint with relatively little force. Also, when the compression part is compressed from the side of the film layer, the film layer on one side and the adhesive forming the joint face the bottom of the compression part in the opposing region, causing the adhesive and the fibers of the compression part to intertwine, and the bonding strength of the joint becomes stronger. Therefore, unintended opening of the joint can be suppressed, the airtightness of the packaging can be maintained, and leakage of the cooling agent can be suppressed.

[0037] (Aspect 15) The packaging according to any one of embodiments 1 to 14, wherein, in a folded state, the packaging material has a facing region opposite to the one side, the film layer of the one side has a joint portion joined to the nonwoven fabric layer of the facing region by adhesive along the transverse direction, the nonwoven fabric layer is a nonwoven fabric layer containing long fibers, and the nonwoven fabric layer of the facing region has the long fibers that straddle the joint portion in the longitudinal direction.

[0038] According to embodiment 15, the long fibers intertwine with other fibers on both sides in the longitudinal direction of the joint, so when a force is applied to peel the joint when opening the package, the long fibers do not immediately come loose but resist the opening force. Therefore, the adhesive becomes easier to break, and the film layer and the nonwoven fabric layer can be easily and cleanly separated between the layers.

[0039] (Aspect 16) A packaging according to any one of embodiments 1 to 15, wherein the non-skin side of the absorbent article is fixed to the packaging material such that the longitudinal direction of the absorbent article is aligned with the longitudinal direction of the packaging material, a plurality of welded portions are provided at the longitudinal end of the absorbent article, and the cooling agent is present in the portion of the non-skin side of the absorbent article that is not fixed to the packaging material and has an uneven shape formed by the plurality of welded portions.

[0040] According to embodiment 16, when the user opens the package, they can feel the cooling agent from the non-skin side of the absorbent article that has been peeled off from the packaging material. Therefore, the user can easily recognize that the absorbent article inside the package contains a cooling agent.

[0041] (Aspect 17) The packaging according to any one of embodiments 1 to 16, wherein the film layer has an uneven surface on the side opposite to the nonwoven fabric layer, and the pair of lateral sides have side joints where the folded packaging material is joined, and at least one of the following is satisfied: the side joints are joined intermittently in the longitudinal direction and the joints are joined intermittently in the lateral direction, and the absorbent article is of the pant type, and the sides of the front waist portion and the rear waist portion in the left-right direction are joined by a plurality of welded joints, and the average value of the unevenness depth of the film layer is smaller than the average value of the unevenness depth of the sides of the absorbent article.

[0042] According to embodiment 17, the small depth of the unevenness in the film layer allows the cooling agent to be retained while reducing the gap between the film layer and the opposing packaging material during intermittent joining, thereby suppressing leakage of the cooling agent. On the other hand, the large depth of the unevenness on the sides of the absorbent article allows more volatile fragrance to be retained on the sides (side joining parts). Therefore, the user can easily feel the cooling agent when opening the package and also when unfolding the package.

[0043] (Aspect 18) A package according to any one of embodiments 1 to 17, wherein, when the packaging material is folded, it has a facing region opposite to the one side, the film layer of the one side has a joint portion joined to the nonwoven fabric layer of the facing region by adhesive along the transverse direction, a fastening tape is provided spanning the end of the one side of the packaging material in the longitudinal direction, and when the package is viewed in the thickness direction, the joint portion has an overlapping region that overlaps with the fastening tape and a non-overlapping region that does not overlap with the fastening tape, and the peel strength for opening the overlapping region is stronger than the peel strength for opening the non-overlapping region.

[0044] According to embodiment 18, the joint beneath the fastening tape is difficult to peel off, preventing the fastening tape from peeling and unintentionally opening the joint in the overlapping area. Therefore, the airtightness of the packaging is maintained, and leakage of the cooling agent can be suppressed. In addition, since the user grasps the fastening tape or its vicinity when opening, force is easily transmitted to the overlapping area. Therefore, even if the peeling strength of the overlapping area is strong, the joint can be opened smoothly.

[0045] ===First Embodiment=== In the first embodiment, the packaging of a sanitary napkin, which is used by fixing it to underwear, is used as an example of a package in which an absorbent article is wrapped in packaging material. However, the absorbent article is not limited to the above, and may be, for example, a light incontinence pad or a panty liner. Also, the person who will wear the absorbent article is not limited to an adult, but may be a child or an animal.

[0046] <<Basic configuration of packaging 1>> Figure 1 is a plan view of the folded packaging 1. Figure 2 is a plan view of the unfolded packaging 1 as seen from the inside. Figure 3 is an explanatory diagram of the non-skin side of the napkin 10, and is a hypothetical representation of the packaging material 20. The folded packaging 1 has longitudinal, transverse, and thickness directions that are perpendicular to each other. The packaging 1 comprises a sanitary napkin 10 (hereinafter also referred to as "napkin 10") and packaging material 20 that packages the napkin 10.

[0047] The packaging material 20, in its unfolded state, is rectangular in shape and has longitudinal, transverse, and thickness directions that are perpendicular to each other. The longitudinal direction of the packaging material 20 is aligned with the longitudinal direction of the package 1. "Unfolded state" refers to the state in which the package 1 in its packaged state is opened and all folded parts are unfolded, as shown in Figure 2. In its unfolded state, the packaging material 20 has one side portion 20A including one side end 20a and the other side portion 20B including the other side end 20b in the longitudinal direction (vertical direction). 。 A fastening tape 2 is provided on one side 20A of the packaging material 20.

[0048] The napkin 10 is detachably fixed to the inner surface of the packaging material 20 with its skin-side facing upward, and is folded together with the packaging material 20 at two folds F1 and F2 that run along the transverse direction. The pair of wing portions 10w of the napkin 10 are each folded inward in the transverse direction. The packaging material 20 is also folded so that one side portion 20A (one side end 20a) is exposed. The first fold F1 on one side in the longitudinal direction is the fold that is unfolded first, and the second fold F2 on the other side in the longitudinal direction is the fold that is unfolded second. In this embodiment, the packaging 1 is tri-folded at two folds F1 and F2, but is not limited to this. For example, it may be a packaging that is quad-folded at three folds.

[0049] <<Basic composition of 10 sanitary napkins>> Figure 4 is a schematic cross-sectional view of the napkin 10. Figure 5 is an explanatory diagram of the application area of ​​the cooling agent 30. The napkin 10 has longitudinal, transverse, and thickness directions that are perpendicular to each other. The longitudinal direction of the napkin 10 is aligned with the longitudinal direction of the packaging body 1 and the longitudinal direction of the packaging material 20. In the thickness direction of the napkin 10, the side that comes into contact with the wearer's skin is also called the "skin side," and the opposite side is also called the "non-skin side."

[0050] As shown in Figure 4, the napkin 10 has a skin-side sheet 11, an intermediate sheet 12, an absorbent core 13, a leak-proof sheet 14, and a pair of side sheets 15. Materials adjacent to each other in the thickness direction are joined together by an adhesive (not shown). The skin-side sheet 11 and the intermediate sheet 12 are permeable sheet materials (e.g., nonwoven fabric), and the leak-proof sheet 14 is a liquid-impermeable sheet material (e.g., resin film). The side sheets 15 extend laterally outward from the lateral end of the skin-side surface of the skin-side sheet 11. A hydrophobic sheet material can be exemplified as the side sheets 15.

[0051] The napkin 10 has a pair of wing portions 10w extending from the center in the longitudinal direction to both outer sides in the width direction. The wing portions 10w are formed by a side sheet 15 and a leak-proof sheet 14, and a wing sheet 16 may be provided between them. The napkin 10 does not have to have wing portions 10w.

[0052] The absorbent body 13 is a component that absorbs and retains excretory fluid, and comprises an absorbent core 131 and a cover sheet 132 that covers the absorbent core 131. An example of the absorbent core 131 is a liquid-absorbing fiber (e.g., pulp fiber) molded into a predetermined shape. An example of the cover sheet 132 is a liquid-permeable sheet (e.g., tissue).

[0053] The napkin 10 is provided with multiple compression sections E. In the compression sections E, a portion of the napkin 10 (for example, from the skin-facing sheet 11 to the absorbent layer 13) is compressed in the thickness direction. The multiple compression sections E may be arranged in a linear fashion or dispersed throughout the napkin.

[0054] As shown in Figure 3, the non-skin side of the napkin 10 is provided with multiple central adhesive sections 17 to which adhesive is applied. The central adhesive sections 17 are rectangular in shape with their longer sides in the longitudinal direction, and multiple central adhesive sections 17 are arranged with spacing in the width direction. The napkin 10 is fixed to the underwear or other clothing by being joined to the skin side of the central adhesive sections 17. Wing adhesive sections 18 are also provided on the non-skin side of the wing section 10w. When the napkin 10 is used, the wing section 10w is folded and joined to the non-skin side of the clothing.

[0055] The napkin 10 is equipped with a cooling agent 30 between the skin-facing sheet 11 and the middle sheet 12 to provide the wearer with a cooling or refreshing sensation. As the cooling agent 30, substances that sublimate easily at room temperature and pressure (for example, 20°C, 1 atm) (i.e., volatile substances) such as menthol, menthyl lactate, or menthol glycerin acetal (MGA) can be used.

[0056] However, the cooling agent 30 is not limited to the above, and any cooling agent used in this art can be used, for example, eucalyptol, camphor, isopulegol, eucalyptus oil, peppermint oil, methyl salicylate, menthyl ethylaminooxalic acid, menthyl succinate, 3-(menthyloxy)propane-1,2-diol, 3-l-menthoxy-2-methylpropane-1,2-diol, p-menthane-3,8-diol, N-ethyl-p-menthane-3-carbamide, etc.

[0057] Furthermore, the cooling agent 30 is preferably applied to the napkin 10 together with the solvent. The solvent is a liquid substance that dissolves or disperses the cooling agent, and any solvent used in this art can be used. For example, lipophilic solvents and hydrophilic solvents can be used as solvents. For example, if the solvent is mainly composed of water, it is preferable that the solvent contains dipropylene glycol or propylene glycol. This allows the cooling agent 30 to be dissolved.

[0058] In this embodiment, the cooling agent 30 is applied to the non-skin side of the skin-side sheet 11 in the pattern shown in Figure 5. Specifically, multiple elongated rectangular patterns, continuous from one end to the other in the longitudinal direction of the skin-side sheet 11, are arranged horizontally. However, the application pattern of the cooling agent 30 is not particularly limited. Furthermore, the application position of the cooling agent 30 is not particularly limited and may be between the intermediate sheet 12 and the absorbent 13, or on the non-skin side of the side sheet 15, etc.

[0059] Furthermore, although not shown in the diagram, an oil film layer (such as triacylglycerol) may be provided on the skin side (for example, the skin side of the skin-facing sheet 11) of the area to which the cooling agent 30 is applied. This prevents the cooling agent 30 from directly contacting the wearer's genital area. Alternatively, the cooling agent 30 may be placed on the napkin 10 encapsulated in microcapsules. In this case, if the microcapsules are damaged by water or external force, the cooling agent 30 will be released to the outside.

[0060] <<Regarding the composition of packaging material 20>> Figures 6A to 6C are explanatory diagrams of the packaging material 20. Figure 6A is a schematic cross-sectional view illustrating the structure of the packaging material 20. Figure 6B is a schematic cross-sectional view illustrating the surface shape of the packaging material 20. Figure 6C is a schematic cross-sectional view illustrating a comparative example packaging material 1020, which is different from this embodiment. Figure 7 is an enlarged image of the cross-section of the packaging material 20.

[0061] As shown in Figure 6A, the packaging material 20 is a sheet having a nonwoven fabric layer 21 with an uneven surface and a film layer 22 with an uneven surface, and the nonwoven fabric layer 21 and the film layer 22 are laminated together. The nonwoven fabric layer 21 is located on one side in the thickness direction of the packaging material 20, and the film layer 22 is located on the other side in the thickness direction. Note that the packaging material 20 only needs to have at least the nonwoven fabric layer 21 and the film layer 22, and may also have a configuration that includes other layers.

[0062] The nonwoven fabric layer 21 is a nonwoven fabric layer containing long fibers (for example, fibers with an average fiber length exceeding 100 mm), and spunbond nonwoven fabrics are an example. Spunbond nonwoven fabrics are generally formed into a sheet by melting resin chips, which are the raw materials, to form long fibers (spinning), and then heat-sealing the fiber web formed by intertwining these long fibers. Therefore, multiple fused parts formed by the heat-sealing treatment are scattered on the surface of the nonwoven fabric layer 21. For this reason, it is preferable that the nonwoven fabric layer 21 contains heat-sealable fibers. Examples of heat-sealable fibers include fibers of olefin resins such as polyethylene (PE), polypropylene (PP), and ethylene-vinyl acetate copolymer (EVA), fibers of polyester resins such as polyethylene terephthalate (PET) and polylactic acid (PLA), and fibers of polyamide resins such as nylon 6. These resins may be used alone or in combination of two or more types of resins.

[0063] The film layer 22 has a first layer 221, a second layer 222, and an intermediate layer 223 located between them. The first layer 221 and the second layer 222 are welding layers containing a substance that enables welding of the packaging materials 20 together, and layers containing olefin resin can be exemplified. In this embodiment, the first layer 221 and the second layer 222 are polyethylene (PE) layers.

[0064] The intermediate layer 223 is a low-permeability layer (gas barrier layer) with lower oxygen permeability than the first layer 221 and the second layer 222. The intermediate layer 223 can suppress leakage of the cooling agent 30 to the outside of the packaging 1. In this embodiment, the intermediate layer 223 is a layer of ethylene-vinyl alcohol copolymer (EVOH). Other examples of low-permeability layers include a film layer treated with metal vapor deposition such as aluminum, an aluminum foil layer, a resin layer such as polyethylene terephthalate (PET) or biaxially oriented polypropylene (OPP), and a film treated with silicon dioxide (silica).

[0065] The first layer 221 and the second layer 222 may be, for example, layers of modified polyethylene containing an adhesive resin (maleic acid). In this case, the first layer 221, the intermediate layer 223, and the second layer 222 can be joined to each other by the adhesive resin. The first layer 221 and the second layer 222 do not necessarily have to contain an adhesive resin; in that case, layers of modified polyethylene or adhesive can be provided between each layer. However, the configuration of the film layer 22 is not limited to the above, and for example, it may have a configuration having either the first layer 221 or the second layer 222 (welding layer), or it may have a configuration without a low-permeability layer (intermediate layer 223), or it may consist only of a low-permeability layer.

[0066] Furthermore, as shown in Figure 6B, the other side surface 22I of the film layer 22 (the side opposite to the nonwoven fabric layer 21) in the thickness direction has an uneven shape. However, the average value of the unevenness depth (h22) of the other side surface 22I of the film layer 22 is smaller than the average value of the unevenness depth (h21) of one side surface 21O of the nonwoven fabric layer 21. The unevenness depth (h21, h22) is the height of the protrusions, as shown in Figures 6B and 7, and is the length in the thickness direction from the top of the protrusion to the bottom of the recess adjacent to the protrusion.

[0067] Here, we will describe the comparative example packaging material 1020 (Figure 6C). The comparative example packaging material 1020 is a sheet in which adhesive H is applied to one of the nonwoven fabric layer 1021 and film layer 1022, the adhesive H is dried and the solvent is evaporated, and then the other layer is placed on top and bonded together while applying heat and pressure. As a result, as shown in Figure 6C, the other side of the comparative example packaging material 1020 is smooth without any uneven shape.

[0068] In contrast, the packaging material 20 of this embodiment is a sheet formed by melting the resin constituting the film layer 22, merging it with the nonwoven fabric layer 21, and then co-pressing (pressuring) the nonwoven fabric layer 21 and the film layer 22 on a flat surface. As a result, the resin of the film layer 22 conforms to the irregularities on the surface of the nonwoven fabric layer 21 or impregnates between the fibers of the nonwoven fabric layer 21, so that the other side surface 22I of the film layer 22 becomes an uneven surface. However, since the film layer 22 does not perfectly conform to the irregularities of the nonwoven fabric layer 21, the average value of the depth of the irregularities on the other side surface 22I of the film layer 22 is smaller than the average value of the depth of the irregularities on one side surface 21O of the nonwoven fabric layer 21. Preferably, the average value of the depth of the irregularities on the other side surface 22I of the film layer 22 is 1 μm or more. By doing so, the feel of the film layer 22 can be improved compared to when the other side of the film layer is smooth (for example, when the average depth of the unevenness is less than 1 μm), and the packaging material 20 can be gripped securely.

[0069] The manufacturing method for the packaging material 20 described above is merely an example and is not limited thereto. For example, the nonwoven fabric layer 21 may be formed with a pressure roller having irregularities on its outer surface, while the film layer 22 may be formed with a pressure roller having shallower irregularities than the aforementioned irregularities. In this case as well, the depth of the irregularities in the film layer 22 will be smaller than the depth of the irregularities in the nonwoven fabric layer 21.

[0070] The average value of the unevenness depth of the film layer 22 and the average value of the unevenness depth of the nonwoven fabric layer 21 can be compared using a well-known method. For example, after freezing the packaging material 20 with liquid nitrogen, a sample is prepared by cutting it along one or both of the longitudinal and transverse directions. At this time, it is preferable to cut the packaging material 20 with a sharp cutter knife so as not to deform the unevenness. Then, the cut surface of the sample is magnified and photographed using a microscope (for example, a VX-7000 manufactured by Keyence Corporation, or an equivalent). In the captured image, a number of arbitrary protrusions are selected from one side surface 21O of the nonwoven fabric layer 21 and the other side surface 22I of the film layer 22, and the depth of the unevenness (height of the protrusions in the thickness direction) is measured. The average value of the unevenness depth of each surface is calculated and compared. Preferably, multiple samples are prepared from the packaging material 20, and the unevenness depth is measured for multiple cross-sectional images of the packaging material 20.

[0071] Figure 7 shows an image of a cross-section of the packaging material 20, which was actually created using the method described above, taken at 1000x magnification, after cutting along its longitudinal direction. In the film layer 22, the size of the first protrusion h22(1) was 2.6 μm, the size of the second protrusion h22(2) was 3.1 μm, and the size of the third protrusion h22(3) was 2.7 μm, with an average value of 2.8 μm. In the nonwoven fabric layer 21, the size of the first protrusion h21(1) was 10.0 μm, the size of the second protrusion h21(2) was 13.2 μm, and the size of the third protrusion h21(3) was 9.8 μm, with an average value of 11.0 μm. Therefore, the average value of the unevenness depth on the other side surface 22I of the film layer 22 was smaller than the average value of the unevenness depth on one side surface 21O of the nonwoven fabric layer 21.

[0072] <<Regarding the refreshing sensation upon opening package 1>> In this embodiment, the napkin 10 is folded along two lateral folds F1 and F2 together with the packaging material 20 to form a package 1 (see Figure 1), and one or more package 1s are distributed to the market in a predetermined storage member (package). Figure 8 is a diagram illustrating an example of a package 6 that houses the package 1s. In Figure 8, multiple package 1s are arranged in the thickness direction and housed in a roughly rectangular parallelepiped package 6. Examples of materials that form the package 6 include highly airtight resin film. The shape and structure of the package 6 are not particularly limited; for example, it may be a self-standing bag, a bag with a zipper that can be resealed after opening, etc. Also, the number of package 1s housed in the package 6 may be one or more. Because the package 1s are housed in such a highly airtight package 6, the cooling agent 30 provided in the package 1 is prevented from diffusing into the atmosphere (outside the package 6), and the loss of the cooling sensation before the napkin 1 is used is prevented.

[0073] A user who obtains (purchases) package 6 opens the package 6, takes out the packaging 1, and begins use. First, the folded packaging material 20 is unfolded, and the napkin 10 is taken out. Figure 9 is a schematic cross-sectional view of the packaging 1. Note that the napkin 10 is not shown in Figure 9. Figure 10 is a plan view showing the state after the initial fold F1 has been unfolded.

[0074] The packaging body 1, in its folded state, has a first joint 41 and a second joint 42 (see Figures 1, 9, 10, etc.). The first joint 41 is a side joint where the folded packaging material 20 is joined by welding on a pair of lateral sides of the packaging material 20. The first joint 41 has a plurality of welded parts 411 formed by known welding means such as heat welding or ultrasonic welding. The plurality of welded parts 411 are arranged intermittently in the longitudinal and transverse directions.

[0075] Furthermore, as shown in Figure 9, the packaging material 20 has a facing region 20C that faces one side portion 20A in the vertical direction when folded. The second joint portion 42 is a joint in which the film layer 22 of one side portion 20A of the packaging material 20 is joined to the nonwoven fabric layer 21 of the facing region 20C with an adhesive such as hot melt adhesive HMA. That is, in the package 1, the region where one side portion 20A and the facing region 20C face each other is sealed at the lateral end of the packaging material 20 by the first joint portion 41 (side joint portion) and at the vertical end (one side end 20a) by the second joint portion 42 (joint portion).

[0076] Furthermore, in the packaging 1 of this embodiment, the cooling agent 30 is present in the nonwoven fabric layer 21 in the region on the other side 20B of the opposing region 20C, in the region where the cooling agent 30 is located. Specifically, the cooling agent present portion 31 is provided in the nonwoven fabric layer 21 in a range along the surface of the packaging material 20, from the end 42e of the second joining portion 42 in the vertical direction (the end opposite to the folded portion F2 side) to the other side end 20b of the packaging material 20. As described above, the region where one side 20A and the opposing region 20C face each other is a sealed space, and because the cooling agent present portion 31 is provided within this sealed region, the cooling agent 30 is less likely to leak out of the packaging 1. In addition, the film layer 22 has higher airtightness in its thickness direction compared to the nonwoven fabric layer 21, which has large gaps between fibers. Therefore, with packaging material 20, the cooling agent 30 contained in the napkin 10 is less likely to leak out from the surface of the packaging body 1 compared to packaging material composed only of a nonwoven fabric layer. As a result, a large amount of the cooling agent 30 is more likely to remain on the napkin 10 until it is used.

[0077] The cooling agent 30 present in the inner cooling agent area 31 may be formed when the cooling agent 30 (see Figure 5) applied to the non-skin side of the skin-side sheet 11 of the napkin 10 volatilizes and moves to adhere to the surface, or the cooling agent 30 may be applied separately to the nonwoven fabric layer 21 of the opposing region 20C.

[0078] When using the napkin 10, the first joint 41 (side joint) and the second joint 42 (joint) are peeled apart, and one side 20A of the packaging material 20, which was folded at the first fold F1 (F1o in Figure 9), is unfolded as shown in Figure 10. At this time, the opposing region 20C (inner cooling agent area 31) that was covered by one side 20A is exposed to the outside, and the cooling agent 30 present in the exposed inner cooling agent area 31 diffuses into the air, causing the user to feel cool and refreshed.

[0079] Furthermore, by peeling off the first joint 41 (side joint), the packaging material 20 that was folded at the second folding part F2 is unfolded, and the wing part 10w is also unfolded, resulting in the unfolded state shown in Figure 2. The napkin 10 can then be removed from the packaging material 20, making it possible to attach the napkin 10. When the napkin 10 is unfolded, the cooling agent 30 applied to the skin-side sheet 11 is more easily diffused into the air. When the napkin 10 is attached, the skin-side sheet 11 with the cooling agent 30 applied comes into direct contact with the wearer's (user's) skin, making it easier for the wearer (user) to feel the coolness and refreshing sensation.

[0080] Furthermore, in the packaging 1 of this embodiment, a cooling agent is also present in the nonwoven fabric layer 21 of the outermost packaging material 20. In Figure 9, at least the nonwoven fabric layer 21 constituting the outermost layer of one side portion 20A is provided with an "outer cooling agent presence area 32" where the cooling agent 30 is present. The cooling agent 30 present in the outer cooling agent presence area 32 is not provided in a sealed space like the inner cooling agent presence area 31, so it is prone to diffusing to the outside of the packaging 1. However, if the packaging 1 is housed in a highly airtight package 6, leakage of the cooling agent 30 to the outside of the package 6 is suppressed, so the cooling agent 30 tends to remain in the outer cooling agent presence area 32 before the packaging 1 is removed from the package 6. Then, when the packaging 1 is removed from the package 6, the cooling agent 30 present in the outer cooling agent presence area 32 diffuses into the atmosphere, making it easier for the user to recall a feeling of coolness or freshness.

[0081] The cooling agent 30 present in the outer cooling agent area 32 may be formed when the cooling agent 30 applied to the non-skin side of the skin-side sheet 11 of the napkin 10 volatilizes, passes through the multiple welded parts 411 intermittently arranged in the first joint 41, and moves to the outside of the packaging body 1 and adheres to it, or the cooling agent 30 may be separately applied to the nonwoven fabric layer 21 of one side part 20A.

[0082] In this embodiment, when the package 1 is removed from the package 6 and the folded packaging material 20 and napkin 10 are unfolded, the weight of the cooling agent 30 per unit area of ​​the skin-facing sheet 13 of the unfolded napkin 10 is greater than the weight of the cooling agent 30 per unit area of ​​the nonwoven fabric layer 21 on one side 20A of the packaging material 20. With this configuration, when the package 1 is removed from the package 6, the cooling agent 30 provided on the nonwoven fabric layer 21 on one side 20A of the packaging material 20 makes it easier for the user to feel a sense of coolness even before opening the package 1 (i.e., before starting to use the napkin 10). Furthermore, when the napkin 10 is put on after opening the package 1 and unfolding it (i.e., after starting to use the napkin 10), since more cooling agent 30 is provided on the skin-facing sheet 13 of the napkin 10, it is easier for the user to feel a sense of coolness.

[0083] The weight of the cooling agent 30 present per unit area of ​​the nonwoven fabric layer 21 and the skin-side sheet 13 can be obtained by measuring the cooling agent components using headspace solid-phase microextraction. Specifically, a gas chromatograph-mass spectrometer (Shimadzu GCMS-QP2010 Plus) is used, with helium as the carrier gas, and the measurement mode is set to scanning, using the electron shock ionization method. First, the part to be measured is cut out from the unfolded packaging 1 to be used as a sample. Here, the unfolded packaging material 20 is cut along the fold F1, and one side 20A is cut out to separate the nonwoven fabric layer 21 from the film layer 22 to obtain the first sample. In addition, the skin-side sheet 13 is separated from the napkin 10 to obtain the second sample. When separating the skin-side sheet 13, etc., it may be possible to cool it by spraying a cooling spray before separation.

[0084] The first sample is folded and rolled up so that the side of the nonwoven fabric layer 21 that was not facing the film layer 22 (the outermost side of the packaging material 20) is facing outwards, and placed in a 300 ml beaker. Similarly, the second sample is folded and rolled up so that the skin-facing side of the skin-side sheet 13 (the side of the napkin 10 closest to the skin) is facing outwards, and placed in a 300 ml beaker. The tops of each beaker are then covered with aluminum foil, and then covered with plastic paraffin film from above, sealing the beakers, and the beakers are placed in a 37-degree Celsius constant temperature water bath. SPME fibers (Sigma-Aldrich 50 / 39 μm DVB / CAR / PDMS, Stableflex 2 cm) are inserted into the beakers through the aluminum foil, and the cooling agent components in each sample are extracted for 50 minutes. After that, the SPME fibers removed from the beakers are immediately measured using a gas chromatograph-mass spectrometer. The resulting masses are then divided by the area of ​​the first sample and the area of ​​the second sample to calculate their respective values.

[0085] This allows us to obtain the weight of the cooling agent per unit area of ​​the nonwoven fabric layer 21 (first sample) on one side 20A of the packaging material 20 and the weight of the cooling agent per unit area of ​​the skin-facing sheet 13 (second sample) of the napkin 10, and compare the two.

[0086] Furthermore, in this embodiment, the packaging material 20 has an outer cooling agent area 32 where the cooling agent is present in the nonwoven fabric layer 21 on one side 20A, and an inner cooling agent area 31 where the cooling agent is present in the nonwoven fabric layer 21 in the region of the opposing region 20C that is on the other side of the second joint 42 (joint). With this configuration, when the packaged body 1 is removed from the package 6, the cooling agent 30 provided on the nonwoven fabric layer 21 of the outermost layer of the packaging material 20, the one side 20A, makes it easier for the user to recall a feeling of coolness even before opening the packaged body 1 (before starting to use the napkin 10). Then, when the napkin 10 is attached after opening the packaged body 1 and unfolding it (after starting to use the napkin 10), the cooling agent 30 is provided on the nonwoven fabric layer 21 of the opposing region 20C that is exposed when the packaging material 20 is opened, making it easier for the user to recall a feeling of coolness.

[0087] Furthermore, the presence of cooling agent components 31 and 32 in the target area of ​​the nonwoven fabric layer 21 can be confirmed by well-known methods. For example, the target area can be cut out from the packaging 1, and the detection of components of the cooling agent 30 can be confirmed using well-known analytical methods such as gas chromatography or liquid chromatography.

[0088] In this case, it is preferable that the weight of the cooling agent 30 per unit area of ​​the nonwoven fabric layer 21 in the region of the opposing region 20C that is on the side of the second joint 42 (joint) is greater than the weight of the cooling agent 30 per unit area of ​​the nonwoven fabric layer 21 in one side portion 20A of the packaging material 20. In other words, it is preferable that there is more cooling agent 30 per unit area of ​​the inner cooling agent portion 31 than there is more cooling agent 30 per unit area of ​​the outer cooling agent portion 32. With this configuration, since the cooling agent 30 is provided in the outermost layer of the packaging body 1, it is possible to easily evoke a feeling of coolness in the user even before opening the packaging body 1 (before starting to use the napkin 10). Then, when the packaging body 1 is opened and the opposing region 20C is exposed (after starting to use the napkin 10), since there is more cooling agent in the inner cooling agent portion 31, it is possible to generate a greater feeling of coolness in the user.

[0089] Furthermore, the packaging material 20 of the packaging body 1 has a laminated structure in which a nonwoven fabric layer 21 is located on one side in the thickness direction, and a film layer 22 is located adjacent to the other side of the nonwoven fabric layer 21 (see Figure 6A). Preferably, the other side surface of the film layer 22 has a portion where the cooling agent 30 is present. For example, in the one side portion 20A of the packaging body 1 in Figure 9, the other side surface of the film layer 22 is folded inward, making it difficult to expose to the outside. In this case, because the cooling agent 30 is present on the other side surface of the film layer 22 that is difficult to expose to the outside, when the packaging body 1 is opened, the cooling agent 30 on the other side surface of the film layer 22 can easily diffuse into the air, making it easier to create a cooling sensation in the user.

[0090] Furthermore, the cooling agent 30 provided in the packaging 1 is preferably menthol or a substance with a larger molecular weight than menthol. Examples of substances with a larger molecular weight than menthol include menthol glycerin acetal (MGA) and menthyl lactate. Since menthol is a substance that easily volatilizes at room temperature and pressure (20°C, 1 atm), when the user opens the packaging 1, the volatile cooling agent 30 can easily diffuse into the atmosphere, making it easier for the user to experience a cooling sensation. In addition, since menthol glycerin acetal (MGA) and menthyl lactate have lower volatility compared to menthol, the cooling agent 30 present in the nonwoven fabric layer 21 located in the outermost layer of the packaging 1 (e.g., the outer cooling agent area 32), the nonwoven fabric layer 21 in the opposing region 20C (e.g., the inner cooling agent area 31), and the skin-side sheet 11 of the napkin 10 is more easily maintained. Therefore, by using such a substance as the cooling agent 30, it is possible to make it easier to create a refreshing sensation in the user before and after starting to use the napkin 10.

[0091] Furthermore, in this embodiment, it is preferable that the nonwoven fabric layer 21 of the packaging material 20 contains long fibers and has multiple high-density areas where the density is higher than that of the surrounding area. The high-density areas (not shown) are, for example, dot-shaped heat-sealed areas (embossing) formed to bond multiple fibers together when manufacturing the nonwoven fabric. In these heat-sealed areas (high-density areas), the fibers fuse together, resulting in a higher density than the surrounding area and the formation of irregularities on the surface of the nonwoven fabric. The formation of irregularities on the surface of the nonwoven fabric makes it easier to retain the cooling agent 30 compared to when the surface is smooth. In addition, because the nonwoven fabric layer 21 contains long fibers, the cooling agent 30 can easily get into the spaces between the entangled long fibers, making it easier to retain the cooling agent 30. Therefore, when a user holds the package 1, they can easily recognize the cooling agent 30 held in the high-density areas (irregularities) of the outermost nonwoven fabric layer 21, making it easier to create a cooling sensation in the user. Furthermore, if the surface of the outermost nonwoven fabric layer 21 of the packaging 1 has irregularities, the packaging 1 will be easier to hold and less slippery, making it easier to perform operations such as opening the packaging 1.

[0092] Furthermore, the packaging body 1 has a non-jointed portion 50 in at least one of the following regions: the region outside the first joint portion 41 in the lateral direction and the region outside the second joint portion 42 in the vertical direction (the region on the side of one end 20a of the packaging material 20), where the packaging material 20 is not joined to itself. In the packaging body 1 of the first embodiment, as shown in Figures 9 and 10, the non-jointed portion 50 is provided in the region outside the second joint portion 42. Specifically, the non-jointed portion 50 is located between the second joint portion 42 in the vertical direction and one end 20a of the packaging material 20, and between the inner end 41a of the first joint portion 41 in the lateral direction and the side end 2s of the fastening tape 2. By providing such a non-jointed portion 50 at one end 20a (opening end) of the packaging material 20, the operation of opening the packaging body 1 can be made easier.

[0093] Figures 11A and 11B are explanatory diagrams of the opening of the packaging 1. When a user opens and unfolds the packaging 1, as shown in Figure 11A, they grasp the other end of the packaging 1 in the longitudinal direction with one hand (left hand in the figure), peel off the fastening tape 2 with the other hand (right hand in the figure), and simultaneously peel back and pinch the non-jointed portion 50 and pull it to one side in the longitudinal direction. At this time, because the packaging material 20 is not joined together at the non-jointed portion 50, the non-jointed portion 50 can be easily pinched. Furthermore, in this embodiment, the non-jointed portion 50 is also provided with the high-density portion (embossing) described above. In other words, the nonwoven fabric layer 21 of the packaging material 20 has multiple high-density portions at the non-jointed portion 50 where the density is higher compared to the surrounding area.

[0094] The non-jointed portion 50 has a high-density area (embossed surface), which makes it easier for the cooling agent 30 to be retained in the irregularities formed on the surface of the nonwoven fabric layer 21, thus making it easier to create a cooling sensation in the user when opening the package 1. In addition, the irregularities formed by the high-density area (embossed surface) make it easier for the nonwoven fabric layer 21 of the packaging material 20 to bend, so that when opening the package 1, it is easier to peel back and pinch the non-jointed portion 50.

[0095] Furthermore, as shown in Figure 6B, in the thickness direction of the packaging material 20, at least a portion of the fibers contained in the nonwoven fabric layer 21 are located on the other side of the film layer 22, relative to the outermost side. In other words, in the packaging material 20, at least a portion of the fibers forming the nonwoven fabric layer 21 are embedded in the resin forming the film layer 22. In this way, because a portion of the fibers are embedded on the film layer 22 side of the interface between the nonwoven fabric layer 21 and the film layer 22, the film layer 22 becomes more easily deformable, using the area around the embedded fibers as a base point, making it easier to handle. And because the film layer 22 is more easily deformable, it becomes easier to open the package 1.

[0096] Furthermore, in the packaging material 20, it is preferable that the thickness of the film layer 22 in the portion where the fibers contained in the nonwoven fabric layer 21 are located on the side of the film layer 22 that is on the side of the outermost surface of the film layer 22 (i.e., the portion where the fibers have penetrated the film layer 22) is thinner than the thickness of the film layer 22 in the portion where the fibers contained in the nonwoven fabric layer 21 are located on the side of the outermost surface of the film layer 22 (i.e., the portion where the fibers have not penetrated the film layer 22). If the film layer 22 is thinner in the portion where the fibers have penetrated the film layer 22, a starting point for bending and deformation of the film layer 22 is more easily formed in that thinner portion, making it easier for the user to handle and making it easier to open the package 1.

[0097] Furthermore, in the film layer 22, the thickness of the intermediate layer 223 in the portion where the fibers contained in the nonwoven fabric layer 21 are located on the side of the film layer 22 that is on the side of the outermost surface is thinner than the thickness of the intermediate layer 223 in the portion where the fibers contained in the nonwoven fabric layer 21 are located on the side of the film layer 22 that is on the side of the outermost surface is thinner. The intermediate layer 223 constituting the film layer 22 has lower oxygen permeability and higher rigidity compared to the welded layers, the first layer 221 and the second layer 222. Therefore, in the portion where the intermediate layer 223 is thinner, it is possible to prevent the cooling agent from leaking out while also making it easier to form a starting point for bending deformation, making it easier to handle in the user's hand and making it easier to open the package 1. In addition, since the intermediate layer 223 is thicker in the portion where the fibers contained in the nonwoven fabric layer 21 are located on the side of the film layer 22 that is on the side of the film layer 22 than in other portions, the rigidity of the film layer 22 is high and the packaging material 20 is less likely to deform. This makes the shape of the packaging 1 less likely to collapse, and the space inside the packaging 1 in which the napkin 10 is contained is more easily maintained stably.

[0098] Furthermore, in Figure 9, the adhesive (HMA) of the second joint 42 is impregnated into the nonwoven fabric layer 21 of the opposing region 20C. Specifically, the adhesive (HMA) is impregnated into the voids between the fibers of the nonwoven fabric layer 21. Therefore, gaps are less likely to form in the thickness direction between the film layer 22 of one side 20A and the nonwoven fabric layer 21 of the opposing region 20C, thereby suppressing leakage of the cooling agent 30. In addition, even if the cooling agent 30 tries to escape to the outside through the spaces between the fibers inside the nonwoven fabric layer 21, its path is blocked and reduced by the adhesive (HMA). This also helps to suppress leakage of the cooling agent 30.

[0099] Furthermore, it is preferable that the adhesive (HMA) impregnating the nonwoven fabric layer 21 in the opposing region 20C does not reach the interior of the film layer 22 in the opposing region 20C. In the packaging material 20 of this embodiment, at the interface between the nonwoven fabric layer 21 and the film layer 22, the fibers of the nonwoven fabric layer 21 and the molten and solidified resin of the film layer 22 become intertwined. Therefore, it is said that the adhesive (HMA) does not reach the interior of the film layer 22 to mean that the adhesive (HMA) is located closer to the nonwoven fabric layer 21 than the resin of the film layer 22 that is located furthest towards the nonwoven fabric layer 21 in the thickness direction within the opposing region 20C. The degree of adhesive impregnation can be observed by taking a magnified photograph of the cross-section of the packaging material 20 (opposing region 20C) where the second joint portion 42 is located using a microscope.

[0100] As described above, the film layer 22 on one side 20A of the packaging material 20 and the film layer 22 on the opposing region 20C are not joined by adhesive, and the user can cleanly peel (open) the film layer 22 on one side 20A and the nonwoven fabric layer 21 on the opposing region 20C between the layers with relatively little force. Also, in the above case, the amount of adhesive is not so large that it impregnates the entire thickness of the nonwoven fabric layer 21 on the opposing region 20C, and the amount of adhesive at the second joint 42 is appropriately suppressed. Therefore, the user can peel off the second joint 42 with relatively little force. Conversely, the nonwoven fabric layer 21 is thick enough that the impregnated adhesive does not reach the film layer 22. Therefore, the strength in the thickness direction of the nonwoven fabric layer 21 is increased, and the adhesive (HMA) at the second joint 42 is more likely to break when the second joint 42 is opened. Therefore, the film layer 22 on one side 20A and the nonwoven fabric layer 21 on the opposing region 20C are cleanly separated.

[0101] Furthermore, as shown in Figure 6B, the other side surface 22I of the film layer 22 (the side opposite to the nonwoven fabric layer 21) in the thickness direction has an uneven surface. Therefore, as shown in Figures 11A and 11B, the feel of the film layer 22 when the user touches it after opening the package 1 can be improved. However, the average value of the unevenness depth (h22) of the other side surface 22I of the film layer 22 is smaller than the average value of the unevenness depth (h21) of the one side surface 21O of the nonwoven fabric layer 21 (the side opposite to the film layer 22). The unevenness depth (h21, h22) is the height of the protrusions, as shown in Figures 6B and 7, and is the length in the thickness direction from the top of the protrusion to the bottom of the recess adjacent to the protrusion.

[0102] If the average depth of the unevenness of the film layer 22 is equal to or greater than the average depth of the unevenness of the nonwoven fabric layer 21, then when the film layers 22 face each other at the first joint 41 (side joint) or when the film layer 22 and the nonwoven fabric layer 21 face each other (see Figure 9), there is a risk that the gap (distance in the thickness direction) between the film layer 22 and the packaging material 20 facing it will become large. On the other hand, if the average depth of the unevenness of the film layer 22 is smaller than the average depth of the unevenness of the nonwoven fabric layer 21, the gap between the opposing film layers 22 and the gap between the film layer 22 and the nonwoven fabric layer 21 can be reduced. Therefore, the nonwoven fabric layer improves the feel of the packaging material to the touch, while ensuring sufficient bonding strength at the first joint 41 (side joint) and other locations, and making it easier to suppress excessive leakage of the cooling agent 30 from the sides of the packaging body 1.

[0103] Furthermore, in the packaging material 20, a compressed section (corresponding to the high-density section described above) is formed during the manufacturing of the nonwoven fabric layer 21, which forms the fiber web into a sheet. This compressed section is compressed from the side opposite to the film layer 22. For example, in Figure 9, in the nonwoven fabric layer 21 of the opposing region 20C, a compressed section is provided on the side facing the adhesive (HMA) forming one side 20A and the second joint 42, with the surface being recessed. In this case, when viewing the packaging 1 in the thickness direction, it is preferable that the second joint 42 has a portion that overlaps with the compressed section of the opposing region 20C.

[0104] By doing so, the bonding area (contact area) between the film layer 22 of one side portion 20A and the nonwoven fabric layer 21 of the opposing region 20C is reduced by the amount of the compressed portion (recess). Specifically, when joining one side portion 20A and the opposing region 20C, the compressed portion (recess) is less susceptible to pressure during joining, and the bonding strength of the second joint portion 42 can be partially weakened. Therefore, the user can open the second joint portion 42 with relatively little force. In addition, the recess of the compressed portion is filled with adhesive (HMA), and the fibers are densely arranged at the bottom of the recess. As a result, the voids within the nonwoven fabric layer 21 are reduced, making it difficult for the cooling agent 30 to leak out through the inside of the nonwoven fabric layer 21.

[0105] On the other hand, contrary to the above case, the compressed portion may be compressed from the side of the film layer 22. In this case as well, when viewing the package 1 in the thickness direction, the second joint portion 42 may have a portion that overlaps with the compressed portion of the opposing region 20C. In this case, the adhesive (HMA) forming the film layer 22 of one side portion 20A and the second joint portion 42 faces the bottom of the compressed portion of the opposing region 20C (the portion where the fibers are densely arranged). As a result, the adhesive (HMA) and the fibers of the compressed portion become intertwined, and the bonding strength of the second joint portion 42 is increased. Consequently, unintended opening of the second joint portion 42 can be suppressed, the airtightness of the package 1 can be maintained, and leakage of the cooling agent 30 can be suppressed.

[0106] Furthermore, although it has been explained that the nonwoven fabric layer 21 of the packaging material 20 contains long fibers, when the nonwoven fabric layer 21 contains long fibers, it is preferable that the nonwoven fabric layer 21 of the opposing region 20C has long fibers that span the second joint portion 42 in the longitudinal direction. Figure 12 is a schematic cross-sectional view illustrating the relationship between the second joint portion 42 and the packaging material 20.

[0107] In Figure 12, if we define the fibers spanning the second joint 42 as long fibers F, then, as shown in Figure 12, the long fibers F continuously traverse the second joint 42 in the longitudinal direction while in contact with the adhesive (HMA) impregnated in the opposing region 20C. These long fibers F intertwine with other fibers on both sides of the second joint 42 in the longitudinal direction. Therefore, when a force is applied to peel the second joint 42 when opening the package 1, the long fibers do not immediately come loose but resist the opening force. Consequently, the adhesive (HMA) becomes easier to break, and the film layer 22 and the nonwoven fabric layer 21 can be easily and cleanly separated between the layers. Alternatively, a portion of the long fibers F may break and adhere to the film layer 22 together with the adhesive HMA. In this case as well, the long fibers F resist the force that causes the adhesive to open, thereby reducing the area in which the nonwoven fabric layer 21 is damaged by the adhesive (HMA), making the nonwoven fabric layer 21 less likely to tear, and allowing the second joint 42 to be cleanly peeled off.

[0108] Furthermore, as shown in Figure 2, the outer edge of the napkin 10 has a welded region 60 in which the material is welded in a predetermined pattern in the thickness direction. The welded region 60 is provided at the longitudinal end of the napkin 10, and as shown in Figure 11B, a plurality of welded parts 61 are provided at intervals within the welded region 60. Therefore, the surface of the longitudinal end of the napkin 10 has an uneven shape (see Figure 3). The uneven shape makes it easier to hold the cooling agent 30 compared to the smooth part. Therefore, it is preferable that the cooling agent 30 be present in the portion of the non-skin side of the napkin 10 that is not fixed to the packaging material 20 and has an uneven shape due to the plurality of welded parts 61 forming the welded region 60.

[0109] By doing so, when the user opens the package 1 as shown in Figure 11B, they can feel the cooling sensation from the non-skin side of the napkin 10 that has been peeled off from the packaging material 20. Therefore, the user can more reliably feel the cooling sensation from the cooling agent 30 and more easily recognize that the napkin 10 inside the package 1 contains the cooling agent 30.

[0110] Figure 13 is an explanatory diagram of the fastening tape 2, and is an enlarged view of region Q in Figure 1. As shown in Figure 13, looking at the packaging 1 in the thickness direction, the second joint 42 has an overlapping region R1 that overlaps with the fastening tape 2 and a non-overlapping region R2 that does not overlap with the fastening tape 2. In this case, it is preferable that the peel strength for opening the second joint 42 in the overlapping region R1 is stronger than the peel strength for opening the second joint 42 in the non-overlapping region R2. By doing so, the second joint 42 under the fastening tape 2 is difficult to peel off, and the fastening tape 2 does not peel off, preventing the second joint 42 in the overlapping region R1 from being unintentionally opened. Therefore, the airtightness of the packaging 1 is maintained, and leakage of the cooling agent 30 can be suppressed. Also, when opening, the user pinches the fastening tape 2 or its vicinity, so force is easily transmitted to the overlapping region R1. Therefore, even if the peel strength of the overlapping region R1 is strong, the second joint 42 can be opened smoothly.

[0111] The peel strength can be measured using a tensile testing machine. Briefly, with the second joint 42 joined, one side 20A of the packaging material 20 and the portion of the packaging material 20 opposite it are cut out to create sample piece A so that the entire area of ​​the second joint 42 in the overlapping region R1 is included. The lateral length W1 of the overlapping region R1 is measured. Then, one side 20A of the packaging material 20 and the portion of the packaging material 20 opposite it are cut out to length W1 so that the second joint 42 in the non-overlapping region R2 is included to create sample piece B. Then, one end of sample piece A or sample piece B (one side 20A of the packaging material 20) is set in one chuck of the tensile testing machine, and the other end of sample piece A or sample piece B (the area opposite one side 20A of the packaging material 20) is set in the other chuck, and the measurement is performed. For each sample piece, the distance between the chucks is widened until the second joint 42 peels off, and the maximum load during this period is read. This maximum load (N) is compared as the peel strength per unit width (W1) of the sample piece.

[0112] ===Second Embodiment=== Figures 14A to 14E are explanatory diagrams of the folding method of the packaging 80 of the second embodiment. Figures 15A and 15B are explanatory diagrams of the packaging 80 of the second embodiment. Figure 15A is a plan view of the packaging 80, and Figure 15B is a diagram showing the state when the first fold portion f4 is unfolded. In the second embodiment, the packaging material and the absorbent article are not folded together, and the packaging 80 for panty-type sanitary napkins 70 will be used as an example for explanation. The packaging 80 of the second embodiment can also be used as packaging for other absorbent articles, such as pant-type disposable diapers, tape-type disposable diapers, absorbent articles that combine pant-type and tape-type, and urine pads.

[0113] The shorts-type sanitary napkin 70 (panty-type absorbent article) has left-right and up-down directions and comprises an absorbent body (not shown) including an absorbent core, a front waistband portion 71, and a rear waistband portion 72. The sides of the front waistband portion 71 and the rear waistband portion 72 in the left-right direction are joined by a pair of side joints SS. Examples of joining methods for the side joints SS include heat welding, ultrasonic welding, and adhesive bonding. The shorts-type sanitary napkin 70 also contains a cooling agent equivalent to that of the first embodiment.

[0114] In the packaging 80, the panty-type napkin 70 is folded as shown in Figures 14A to 14C. First, as shown in Figure 14A, both sides of the panty-type napkin 70 in the left-right direction are folded inward in the left-right direction at two folds f1 and f2 that run along the top-bottom direction. Next, the panty-type napkin 70 is folded in the top-bottom direction at a fold f3 that runs along the left-right direction. The folded panty-type napkin 70 is then packaged in the packaging material 20 as shown in Figures 14D and 14E. The packaging material 20 of the packaging 80 of the second embodiment has the same configuration as the packaging material 20 of the first embodiment, so a detailed explanation is omitted using common reference numerals.

[0115] As shown in Figure 14D, the folded panty-type napkin 70 is placed in the vertical center of the film layer 22 of the packaging material 20. Then, as shown in Figure 14E, both vertical ends of the packaging material 20 are folded vertically along two folds f4 and f5 that run horizontally. As a result, the nonwoven fabric layer 21 of the packaging material 20 becomes the outermost layer of the package 80, improving the feel of the outermost layer of the package 80.

[0116] Subsequently, a first joint 81 (side joint) is formed at a pair of lateral sides of the packaging material 20, where the folded packaging material 20 is intermittently joined in the vertical direction by welding or the like. Specifically, multiple welded joints 811 are formed intermittently in the vertical and horizontal directions. In addition, a second joint 82 (joint) is formed where the film layer 22 on one side of the packaging material 20, including one side edge 20a, is joined to the opposing nonwoven fabric layer 21 with an adhesive or the like. This suppresses the expansion of the packaging body 80 while making it difficult for the volatile fragrance contained in the shorts-type napkin 70 to leak to the outside of the packaging body 80. However, the invention is not limited to the above; it is sufficient that at least one of the following conditions is met: the first joint 81 intermittently joins the packaging material 20 in the vertical direction, and the second joint 82 intermittently joins the packaging material 20 in the horizontal direction.

[0117] The folding method described above is just one example and is not limited to this. For example, in Figure 14A, the front waistband portion 71 is folded inward, but it may also be folded so that the rear waistband portion 72 is folded inward. Also, the left-right direction of the panty-type napkin 70 is aligned with the vertical direction of the packaging 80 (packaging material 20), but it may also be aligned with the horizontal direction of the packaging 80.

[0118] The packaging 80 of the second embodiment also has a cooling agent presence area 83 in the region on the other side 20b (other side portion 20B) of the packaging material 20, where the cooling agent is present in the nonwoven fabric layer 21, as shown in Figure 15B. This makes it easier for the user to feel the cooling sensation from the cooling agent when opening the packaging 80, and allows the user to recognize that the shorts-type napkin 70 contains a cooling agent.

[0119] Furthermore, as shown in Figure 14A, when the front waistband portion 71 and the rear waistband portion 72 of the shorts-type napkin 70 are joined by multiple welded portions 73, the sides of the shorts-type napkin 70 have an uneven shape. In this case, it is preferable that the average value h22 of the unevenness depth of the film layer 22 (see Figure 6B) is smaller than the average value h73 of the unevenness depth of the sides of the shorts-type napkin 70.

[0120] The small depth of the unevenness of the film layer 22 allows the cooling agent 30 to be retained while reducing the gap between the film layer 22 and the packaging material 20 facing it during the intermittent joints, thereby suppressing leakage of the cooling agent 30. On the other hand, the large depth of the unevenness on the sides of the panty-type napkin 70 allows more volatile fragrance to be retained on the sides (side joint SS). In the packaging 80 of the second embodiment, the unfolding of the packaging material 20 and the unfolding of the panty-type napkin 70 are performed separately. Therefore, the user can feel the cooling agent when opening the packaging 80 due to the cooling agent presence area 83, and can also feel the cooling agent when opening the folds f1 to f3 of the panty-type napkin 70. Thus, the user can be made aware that the panty-type napkin 70 contains a cooling agent.

[0121] The embodiments described above are provided to facilitate understanding of the present invention and are not intended to limit its interpretation. The present invention can be modified and improved without departing from its spirit, and it goes without saying that the present invention includes equivalents thereof. [Explanation of Symbols]
