[Figure 8] FIG. 8 is a diagram for explaining the packaging body 1 according to the fourth embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Specifically, the present disclosure relates to the following aspects: [Aspect 1] A wet wipes package in which a plurality of wipes and a medicinal solution are stored inside a package body, the package body having an inner surface and an outer surface and including an opening for removing the wipes; The packaging body includes a cellulose-based base material layer disposed on the outer surface side and a water-impermeable layer disposed on the inner surface side, the packaging body includes a removal section including the opening, a flap label covering the removal section from the outer surface side so as to be repeatedly openable and closable, and a water-impermeable inner cover member covering the removal section from the inner surface side, The packaging body includes a fixing portion at the removal portion where the inner cover member is fixed to the flap label. A package for wet wipes comprising:

[0009] In the above-mentioned wet wipes package, the inner cover member covering the removal portion from the inside of the wet wipes before use is fixed to the flap label. Therefore, compared with the sheet package disclosed in Patent Document 1, it has a simple structure and can prevent the medicinal liquid from leaking from the wet wipes package before use.

[0010] Furthermore, after the wet wipes package is first used, i.e., when the flap label is first opened, the inner cover member breaks near the outer edge of the fastening portion, resulting in the inner cover member having a broken portion along the outer edge of the fastening portion, at least a portion of which tends to be located inside the opening of the package body.

[0011] Since the above-mentioned packaging body includes a cellulose-based substrate layer, it tends to be harder than a conventional packaging body including a plastic substrate layer, and as a result, when removing the wet wipes, if the wipes come into direct contact with the opening, the medicinal solution impregnated in the wipes may transfer to the cellulose-based substrate layer, and the wipes may get caught in the opening, making it difficult to remove.

[0012] In relation to this, in the above-mentioned wet wipes package, at least a part of the broken portion of the inner cover member is located inside the opening of the package body, and the broken portion of the inner cover member located inside the opening prevents the wipes from directly contacting the opening, and prevents the medicinal solution from migrating to the cellulose-based base material layer and makes it difficult to remove the wipes. In addition, when the cellulose-based base material layer constitutes the outer surface of the package, if the medicinal solution migrates to the cellulose-based base material layer, the medicinal solution is likely to volatilize from the outer surface of the package, and thus the wet wipes package may have difficulty retaining the medicinal solution.

[0013] As described above, the packaging for the wet wipes has a simple structure and is capable of holding the medicinal solution before use, and after use begins, the medicinal solution is less likely to migrate into the cellulose-based substrate, making it easy to remove the wipes.

[0014] [Aspect 2] A packaging body for wet wipes according to aspect 1, wherein an adhesive layer is provided on one or both of the inner surface of the flap label and the outer surface of the inner cover member at the removal section.

[0015] In the above-mentioned wet wipes package, an adhesive layer is provided on one or both of the inner surface of the flap label and the outer surface of the inner cover member. If an adhesive layer is provided on the inner surface of the flap label, when the flap label is closed after starting to use the wet wipes, the portion of the inner cover member that is located inside the opening of the packaging body, for example, part of the broken portion, can adhere to the flap label, making it difficult for the medicinal solution to transfer to the cellulose-based substrate.

[0016] In addition, if an adhesive layer is provided on the outer surface of the inner cover member, when the flap label is closed after starting to use the wet wipes, the portion of the inner cover member that is located inside the opening of the packaging body, for example, part of the broken portion, can adhere to the cellulose-based substrate, the flap label, etc. at the cross section of the opening, making it difficult for the medicinal solution to transfer to the cellulose-based substrate.

[0017] [Aspect 3] A packaging body for wet wipes according to aspect 1 or 2, wherein, at the removal section, the packaging body further includes an impermeable outer cover member having an outer cover member opening between the flap label and the packaging body, and the outer cover member is spaced apart from the inner cover member.

[0018] The wet wipes package includes a predetermined outer cover member. Therefore, when the flap label is opened and closed, the package body is easily protected, and the flap label is less susceptible to the effects of wetting the cellulose-based base material layer. In addition, in the wet wipes package, the outer cover member is separated from the inner cover member. Therefore, the broken portion of the inner cover member located inside the opening is not affected by the outer cover member, and the wipes are prevented from directly contacting the opening, and the transfer of the medicinal solution to the cellulose-based base material layer and the difficulty in removing the wipes can be prevented.

[0019] [Aspect 4] The wet wipes package according to claim 3, wherein the outer cover member has a release surface on the flap label side. In the above-mentioned wet wipes package, the outer cover member has a release surface on the flap label side, so that the flap label has excellent repetitive opening and closing properties.

[0020] [Aspect 5] A wet wipes package according to aspect 3 or 4, wherein in the removal section, the bonding strength between the flap label and the inner cover member in the fixing section is higher than the bonding strength between the flap label and the outer cover member.

[0021] In the wet wipes package, the bonding strength between the flap label and the inner cover member is higher than the bonding strength between the flap label and the outer cover member at the removal section, so that in the wet wipes package, when the flap label is first opened, the inner cover member can accurately have a break portion along the outer edge of the fixing section, and the flap label can accurately and repeatedly open and close the removal section.

[0022] [Aspect 6] The flap label includes a base member disposed on the packaging body side, and a lid member joined to the base member so as to be repeatedly opened and closed, The base member and the cover member are integrally formed, At the fixing portion, the inner cover member is fixed to the base member, and the base member is fixed to the lid member. A package for wet wipes according to any one of aspects 1 to 5.

[0023] In the wet wipes package, the flap label includes a base member and a lid member that are integrally formed. Therefore, when the lid member is opened and closed, the package body is easily protected, and the opening and closing of the lid member is less susceptible to the influence of the wetting of the cellulose-based base material layer, etc. In addition, the wet wipes package can be simplified in structure and manufacture compared to a package in which an outer cover member is provided separately.

[0024] [Aspect 7] A packaging body for wet wipes according to any one of Aspects 1 to 6, wherein the impermeable layer and the inner cover member are integrally formed.

[0025] In the wet wipes packaging, the impermeable layer and the inner cover member are integrally formed, and therefore the wet wipes packaging has a simpler structure, yet is able to retain the medicinal solution before use, and after use, the medicinal solution is less likely to migrate to the cellulose-based substrate, making it easy to remove the wipes.

[0026] [Aspect 8] A wet wipes package according to any one of aspects 1 to 7, wherein in the removal section, the inner cover member has a wall portion that stands toward the flap label and a top portion that contacts the flap label, and in at least a portion of the top portion, the inner cover member is fixed to the flap label to form the fixed portion.

[0027] In the above-mentioned wet wipes package, since the inner cover member has a predetermined wall portion and a top portion, the effect of the first aspect can be more easily achieved.

[0028] [Aspect 9] A packaging body for wet wipes according to aspect 8, wherein the packaging body has a weakened line on the outer edge of the inner cover member constituting the fixing portion for cutting the inner cover member.

[0029] The wet wipes packaging has a predetermined weakened line in the inner cover member, so that when the flap label is first opened, the inner cover member can be easily and reliably cut outside the fixed portion, thereby preventing the medicinal solution from migrating into the cellulose-based base material layer and preventing the wipes from being difficult to remove.

[0030] [Aspect 10] A wet wipes package according to claim 9, wherein the inner cover member has the weakened line located inside the outer edge of the top.

[0031] In the above-mentioned wet wipes package, the inner cover member has a weakened line on the inside of the outer edge of the top. Therefore, after the start of use of the package, the part of the top outside the weakened line prevents the wipe from directly contacting the opening, and prevents the medicinal solution from transferring to the cellulose-based substrate layer and makes it difficult to remove the wipe. In addition, when an adhesive layer is provided on one or both of the inner surface of the flap label and the outer surface of the inner cover member, the part of the top outside the weakened line is more likely to adhere to the flap label when the flap label is closed, making it difficult for the medicinal solution to transfer to the cellulose-based substrate.

[0032] [Aspect 11] The wet wipes package according to any one of Aspects 1 to 10, wherein the cellulosic substrate layer comprises rayon.

[0033] In the above-mentioned wet wipes packaging, since the cellulosic substrate layer contains rayon, the packaging body is more likely to be softer than when the cellulosic substrate contains pulp fiber. Therefore, when the wet wipes packaging is used, noise caused by deformation of the packaging body is less likely to be generated. In addition, the appearance of the wet wipes packaging is more likely to have a luxurious feel.

[0034] The wet wipes packaging of the present disclosure (hereinafter, may be simply referred to as "packaging") will be described in detail below. [First embodiment] 1 to 5 are diagrams for explaining a package 1 for wet wipes according to one embodiment of the present disclosure (hereinafter referred to as "first embodiment"). Specifically, FIG. 1 is a perspective view of the package 1. FIG. 2 is a perspective view showing the package 1 in use. FIG. 3 is a plan view of the package 1. FIG. 4 is a partially enlarged end view of the vicinity of the removal portion 21 in the IV-IV end view of FIG. 3. FIG. 5 is a partially enlarged end view of the vicinity of the removal portion 21 in the IV-IV end view of FIG. 3, showing a state in which the flap label 23 has been opened.

[0035] The packaging body 1 according to the first embodiment has a first direction D1, a second direction D2, and a third direction D3 that are perpendicular to each other. The third direction D3 is the up-down direction of the packaging body 1, the direction in which the wipes 3 are stacked, and the direction in which the wipes 3 are removed. The first direction D1 and the second direction D2 are the longitudinal direction and the width direction of the packaging body 1, respectively.

[0036] In the package 1 according to the first embodiment, a plurality of wipes 3 and a medicinal solution (not shown) are stored inside the package body 5. Each of the wipes 3 is folded and stacked in the third direction D3, but since this is not a characteristic feature of the present disclosure, a detailed description thereof will be omitted. In the packaging body 1 according to the first embodiment, the packaging body 5 is formed into a cylindrical shape by providing a seal portion (not shown) between the ends of the sheet-like packaging body 5 having a first direction D1 and a second direction D2, and is formed into a bag shape by providing end seal portions 101 at both ends in the first direction D1.

[0037] The package body 5 has an inner surface 7 and an outer surface 9, and is provided with an opening 11 for removing the multiple wipes 3. The package body 5 is provided with a cellulosic base material layer 13 disposed on the outer surface 9 side, and an impermeable layer 15 disposed on the inner surface 7 side. The cellulosic base material layer 13 constitutes the outer surface 9 of the package body 5, and the impermeable layer 15 constitutes the inner surface 7 of the package body 5.

[0038] The packaging body 1 has a removal portion 21 including an opening 11. The packaging body 1 also has an outer cover member 17 covering the removal portion 21 from the outer surface 9 side. The outer cover member 17 has an outer cover member opening 19. The outer edge of the outer cover member opening 19 coincides with the outer edge of the opening 11 of the packaging body 5 in the third direction D3.

[0039] The package 1 includes a flap label 23 that covers the removal portion 21 from the outer surface 9 side via the outer cover member 17 so as to be repeatedly openable and closable. The flap label 23 includes a flap label inner surface 31 on the inner surface 7 side and a flap label outer surface 33 on the outer surface 9 side, and an adhesive layer (not shown) is provided on the flap label inner surface 31. The outer cover member 17 also has a release surface on the flap label 23 side that is coated with a release agent, whereby the flap label 23 is joined, specifically attached, to the outer cover member 17 so as to be repeatedly openable and closable.

[0040] The package 1 includes an impermeable inner cover member 25 that covers the removal portion 21 from the inner surface 7 side. The inner cover member 25 includes an inner cover member inner side surface 35 arranged on the inner surface 7 side and an inner cover member outer side surface 37 arranged on the outer surface 9 side, and the inner cover member outer side surface 37 includes an adhesive layer (not shown) coated with an adhesive.

[0041] The packaging body 1 has a fixing portion 27 where the inner cover member 25 is fixed to the flap label 23 at the removal portion. In the removal section 21, the inner cover member 25 has a wall section 41 that stands toward the flap label 23 and a top section 43 that contacts the flap label 23, and the inner cover member 25 is fixed to the flap label 23 at a part of the top section 43 to form the fixed section 27. The package 1 also has a weakened line 45 for cutting the inner cover member 25 at the outer edge (not shown) of the fixed section 27. The weakened line 45 is formed by cutting the inner cover member 25 from the inner surface 35 side of the inner cover member so as to go around the outer edge of the fixed section 27 and not to penetrate the inner cover member 25. The weakened line 45 is also located inside the outer edge of the top section 43.

[0042] When the flap label 23 is first opened, the inner cover member 25 is broken along the weakened line 45 that goes around the outer edge of the fixing portion 27, and the portion of the inner cover member 25 inside the weakened line 45 remains fixed to the flap label 23 and follows the opening and closing of the flap label 23. In the portion of the inner cover member 25 outside the weakened line 45, the inner cover member 25 has a wall portion 41 having a broken portion along the outer edge of the fixing portion 27. The wall portion 41 having a broken portion is disposed inside the opening 11 of the package body 5.

[0043] The package body 5 includes the cellulose-based base material layer 13, and therefore tends to be harder than conventional package bodies that include a plastic base material layer. As a result, when the wipe 3 is taken out, if the wipe 3 comes into direct contact with the opening 11, the medicinal solution impregnated in the wipe 3 may transfer to the cellulose-based base material layer 13, and the wipe 3 may get caught in the opening 11, making it difficult to take out.

[0044] In the wet wipes packaging body 1, the wall portion 41 having the broken portion is positioned inside the opening 11 of the packaging body 5, so that the wall portion 41 having the broken portion prevents the wipes 3 from coming into direct contact with the opening 11, thereby preventing the medicinal solution from migrating into the cellulose-based base material layer 13 and making it difficult to remove the wipes 3.

[0045] In the removal section 21, the bonding strength between the flap label 23 and the inner cover member 25 at the fixing portion 27 is configured to be higher than the bonding strength between the flap label 23 and the outer cover member 17. As a result, when the flap label 23 is first opened, the inner cover member 25 can accurately have a break portion along the outer edge of the fixing portion 27, and the flap label 23 can accurately open and close the removal section 21 repeatedly.

[0046] [Second embodiment] Fig. 6 is a diagram for explaining a package 1 for wet wipes according to another embodiment of the present disclosure (hereinafter referred to as "second embodiment"). Fig. 6 is a diagram corresponding to Fig. 4 in the first embodiment. Note that, in the package 1 according to the second embodiment, the following description will focus on the parts that are different from the package 1 according to the first embodiment, and a description of the same parts will be omitted.

[0047] The packaging body 1 according to the second embodiment comprises a removal section 21 including an opening 11, a flap label 23 covering the removal section 21 from the outer surface 9 side so as to be repeatedly openable and closable, and an impermeable inner cover member 25 covering the removal section 21 from the inner surface 7 side. The flap label 23 includes a base member 51 and a lid member 53 joined to the base member 51 so as to be repeatedly openable and closable. The flap label 23 is disposed not only in the removal section 21 but also beyond the removal section 21 in the first direction (not shown) and the second direction D2.

[0048] The base member 51 and the lid member 53 constituting the flap label 23 are integrally formed and laminated. Specifically, a first adhesive layer (not shown) made of a first adhesive is provided on the inner surface (not shown) of the base member 51, and the base member 51 is fixed to the cellulose-based base material layer 13 of the packaging body 5. The outer surface (not shown) of the base member 51 is a release surface having releasability. A second adhesive layer (not shown) made of a second adhesive is provided on the inner surface (not shown) of the lid member 53, and is bonded to the outer surface (release surface) of the base member 51 so as to be repeatedly opened and closed. Note that the second adhesive has lower adhesion than the first adhesive, and the outer surface of the base member 51 is provided with a release surface, so that the base member 51 can remain fixed to the cellulose-based base material layer 13 when the lid member 53 is opened and closed.

[0049] The inner cover member 25 has a wall portion 41 that stands toward the flap label 23 and a top portion 43 that contacts the flap label 23, and at a part of the top portion 43, the inner cover member 25 is fixed to the base member 51, and the base member 51 is fixed to the lid member 53, thereby forming a fixed portion 27. The package 1 also has a weakened line 45 on the outer edge of the fixed portion 27 for cutting the inner cover member 25 and the base member 51. Specifically, the weakened line 45 is formed by cutting the inner cover member 25 and the base member 51 from the inner cover member 25 side so as to go around the outer edge of the fixed portion 27 and to penetrate the inner cover member 25 but not the base member 51. This makes it easier to reliably cut the inner cover member 25 outside the fixing portion 27 when the flap label 23 is first opened, making it easier to remove the wipes.

[0050] [Third embodiment] Fig. 7 is a diagram for explaining a package 1 for wet wipes according to another embodiment of the present disclosure (hereinafter referred to as "third embodiment"). Fig. 7 is a diagram corresponding to Fig. 4 in the first embodiment. Note that in the package 1 according to the third embodiment, the following description will focus on the parts that are different from the package 1 according to the first embodiment, and a description of the same parts will be omitted.

[0051] The packaging body 1 according to the third embodiment includes a removal section 21 including an opening 11, a flap label 23 covering the removal section 21 from the outer surface 9 side so as to be repeatedly openable and closable, and a water-impermeable inner cover member 25 covering the removal section 21 from the inner surface 7 side. The packaging body 1 includes a fixing portion 27 in the removal section 21 where the inner cover member 25 is fixed to the flap label 23. The impermeable layer 15 and the inner cover member 25 are integrally formed, which allows the packaging body 1 according to the third embodiment to have a simpler structure.

[0052] [Fourth embodiment] Fig. 8 is a diagram for explaining a package 1 for wet wipes according to another embodiment of the present disclosure (hereinafter referred to as "fourth embodiment"). Fig. 8 is a diagram corresponding to Fig. 4 in the first embodiment. Note that in the package 1 according to the third embodiment, the following description will focus on the parts that are different from the package 1 according to the first embodiment, and a description of the same parts will be omitted.

[0053] In the packaging body 1 according to the fourth embodiment, the flap label 23 is directly bonded to the cellulosic base material layer 13 constituting the packaging body 5 so as to be repeatedly openable and closable. This allows the packaging body 1 according to the fourth embodiment to have a simpler structure.

[0054] A package of wet wipes according to the present disclosure may have a first orientation, a second orientation, and a third orientation that are mutually orthogonal. The third direction is a direction in which the wipes are stacked, and the first and second directions can be planar directions of the wipes, for example, the first and second directions can be longitudinal and transverse directions of the package, respectively.

[0055] In the wet wipes packaging of the present disclosure, a plurality of wipes and a medicinal solution are stored inside the packaging body. The wipes are not particularly limited as long as they are used as a substrate for wet wipes in the art, and may include fabrics such as nonwoven fabrics, woven fabrics, and knitted fabrics. The fabric may contain hydrophilic fibers, hydrophobic fibers, heat-fusible fibers, and the like.

[0056] The hydrophilic fibers include cellulosic fibers, such as natural cellulose fibers, regenerated cellulose fibers, refined cellulose fibers, and semi-synthetic cellulose fibers. Examples of the natural cellulose fibers include plant fibers such as pulp fibers, seed hair fibers (eg, cotton fibers), bast fibers (eg, hemp), leaf vein fibers (eg, Manila hemp), and fruit fibers (eg, palm).

[0057] The pulp fibers include those known in the art as pulp fibers, such as wood pulp fibers and non-wood pulp fibers. The wood pulp fibers include, for example, softwood pulp fibers and hardwood pulp fibers. The non-wood pulp fibers include, for example, straw pulp fibers, bagasse pulp fibers, reed pulp fibers, kenaf pulp fibers, mulberry pulp fibers, bamboo pulp fibers, hemp pulp fibers, cotton pulp fibers (e.g., cotton linters), and the like. The pulp fibers may be waste paper, recycled pulp fibers, or the like.

[0058] The cotton fibers include Hirsutum cotton fibers (eg, Upland cotton), Barbadense cotton fibers, Arboreum cotton fibers, and Helbaceum cotton fibers. The cotton fibers can also be organic cotton fibers, pre-organic cotton (trademark) fibers. Organic cotton fibre means cotton that is certified by the Global Organic Textile Standard (GOTS).

[0059] Examples of the regenerated cellulose fibers include rayon, for example, viscose rayon obtained from viscose, polynosic and modal, and cuprammonium rayon (also called "cupra") obtained from a cuprammonium salt solution of cellulose.

[0060] The above-mentioned refined cellulose fiber includes Lyocell, specifically, pulp, which is dissolved in an aqueous solution of N-methylmorpholine N-oxide to prepare a spinning dope (dope), and extruded into a dilute solution of N-methylmorpholine N-oxide to prepare fibers. The above-mentioned refined cellulose is commercially available, for example, under the name Tencel (trademark). The semi-synthetic fibers include semi-synthetic cellulose fibers, such as acetate fibers, for example, triacetate and diacetate fibers.

[0061] The hydrophobic fibers include those commonly used in the art, such as synthetic fibers. The synthetic fibers may include those containing a single component, such as a single fiber, or those containing multiple components, such as a composite fiber. The synthetic fibers may also be biomass plastics, recycled materials, etc.

[0062] Examples of the above components include polyolefin-based polymers such as polyethylene and polypropylene; polyester-based polymers such as terephthalate-based polymers such as polyethylene terephthalate (PET), polybutylene terephthalate, and polypentylene terephthalate; polyamide-based polymers such as nylon 6 and nylon 6,6; acrylic-based polymers; polyacrylonitrile-based polymers; and modified versions thereof.

[0063] The hydrophobic fiber may include the water-repellent cellulosic fiber obtained by treating the cellulosic fiber with a water repellent agent, which may be referred to as a hydrophilic cellulosic fiber for distinction. The water-repellent cellulosic fibers have the following effects: (i) adjacent wet wipe portions are less likely to stick to each other and can be easily separated; and (ii) they are biodegradable, thereby reducing the environmental impact.

[0064] The above-mentioned water-repellent cellulose-based fibers are disclosed, for example, in JP 2002-266241 A, JP 2003-20570 A, JP 2019-65443 A, JP 2022-58301 A, and the like. For example, Ecorepellent (product name, water-repellent viscose rayon) manufactured by Daiwabo Rayon Co., Ltd., and Olea (product name, water-repellent viscose rayon) manufactured by Kelheim Fibres GmbH, and the like are commercially available.

[0065] When the fabric contains the heat-fusible fibers, and heat fusion between the heat-fusible fibers and the heat-fusible fibers, and between the heat-fusible fibers and the cellulosic fibers (water-repellent cellulosic fibers and hydrophilic cellulosic fibers), etc., the strength of the fabric and thus the wet strength of the wet wipes can be increased, and when the heat-fusible fibers are heat-fusible with each other, the strength of the fabric and thus the wet strength of the wet wipes can be further increased.

[0066] The above-mentioned heat-fusible fibers can be any fiber used as a heat-fusible fiber in the art, specifically, fibers containing a thermoplastic resin with a low melting point and a thermoplastic resin with a high melting point, and in order to fuse the heat-fusible fibers together, it is preferable to use a fiber containing a thermoplastic resin with a low melting point, such as a polyethylene resin or a low melting point polypropylene, at least on the surface. Examples of the above-mentioned heat-fusible fibers include single-component fibers of polyethylene resin; single-component fibers of polypropylene resin; core-sheath type composite synthetic fibers with a core of polyethylene terephthalate resin and a sheath of polyethylene resin; core-sheath type composite synthetic fibers with a core of polypropylene resin and a sheath of polyethylene resin; core-sheath type composite synthetic fibers with a core of high melting point polypropylene resin and a sheath of low melting point polypropylene resin; side-by-side type composite synthetic fibers made of polyethylene terephthalate resin and polyethylene resin; side-by-side type composite synthetic fibers made of polypropylene resin and polyethylene resin.

[0067] The heat-fusible fiber is preferably a biodegradable heat-fusible fiber, which makes the fabric, and in turn the wet wipes, more likely to be biodegradable. Examples of the low-melting thermoplastic resin constituting the biodegradable heat-fusible fiber include polybutylene succinate, poly(hydroxybutyrate / hydroxyhexanoate), polycaprolactone, poly(caprolactone / butylene succinate), poly(butylene succinate / adipate), poly(butylene succinate / carbonate), poly(butylene adipate / terephthalate), polyethylene succinate, and polylactic acid.

[0068] Examples of the high melting point thermoplastic resin constituting the biodegradable heat-fusible fiber include polylactic acid, polyhydroxybutyrate, polyglycolic acid, and cellulose acetate. The heat-fusible fibers may be biomass plastics, recycled materials, or the like.

[0069] As the nonwoven fabric, any nonwoven fabric (e.g., spunlace nonwoven fabric, air-through nonwoven fabric, spunbonded nonwoven fabric, point-bonded nonwoven fabric, etc.) produced by a known method such as a dry method, a wet method, a water jet method, a direct spinning method, an air-laid method, a needle punch method, or a felt method can be used, and a spunlace nonwoven fabric having high wet strength is preferred.

[0070] The wipes can be stacked in a third direction as known in the art. For example, the multiple wipes can be stacked from bottom to top in the third direction, and the upper end of the lower wet wipe located on the lower side and the lower end of the upper wet wipe adjacent to it on the upper side can be arranged so that they overlap each other, with the upper end of the lower wet wipe being located higher than the lower end of the upper wet wipe.

[0071] As the above-mentioned chemical solution, those generally used in the art can be used depending on the application of the wet wipes. For example, the chemical solution may include water, a water-soluble solvent, for example, an alcohol, for example, ethanol, an antibacterial agent, an additive, and the like. In the package according to the present disclosure, from the viewpoint of the problem, the drug solution contains water in an amount of preferably 50% by mass or more, more preferably 60% by mass or more, even more preferably 70% by mass or more, even more preferably 80% by mass or more, and even more preferably 90% by mass or more.

[0072] In the package according to the present disclosure, the package body has an inner surface and an outer surface, and is provided with an opening for removing the wipes. The inner surface refers to the surface of the package body on which the wipes and the medicinal solution are held. The packaging body includes a cellulosic base material layer disposed on the outer surface side, and a water-impermeable layer disposed on the inner surface side, and may include other layers.

[0073] The cellulosic substrate layer may be a layer containing the above-mentioned hydrophilic fibers, for example, pulp fibers, regenerated cellulosic fibers (for example, rayon), etc. The cellulosic substrate layer may have a thickness of, for example, 0.05 to 0.5 mm.

[0074] When the cellulosic base material layer contains pulp fibers, the rigidity of the packaging body (packaging) increases, and the packaging body is less likely to be crushed when the packaging body according to the present disclosure is stored in a storage container for use. Furthermore, when the above-mentioned cellulose-based base material layer contains pulp fibers, the rigidity of the packaging body tends to be high, making the wipes more likely to get caught in the opening. However, in the packaging body of the present disclosure, the broken portion of the inner cover member prevents the wipes from coming into direct contact with the opening, thereby making it less difficult to remove the wipes. Furthermore, when the cellulosic base material layer contains pulp fibers, for example, when it contains 50% by mass or more of pulp fibers, the packaging body can be disposed of as paper waste.

[0075] When the above-mentioned cellulose-based base material layer contains regenerated cellulose fibers (e.g., rayon), refined cellulose fibers, semi-synthetic fibers, etc., noise caused by deformation of the packaging body is less likely to be generated when the wet wipes packaging is used, and the wet wipes packaging is more likely to have a luxurious feel.

[0076] The impermeable layer is not particularly limited as long as it does not allow water to pass through, and examples thereof include a barrier layer, a sealant layer, and a combination thereof. Examples of the material for the barrier layer include a resin film such as polyethylene terephthalate or nylon on which alumina, silica, or the like is vapor-deposited. Examples of the material for the sealant layer include thin films having heat sealability, such as low density polyethylene (LDPE) and non-axially oriented polypropylene (CPP).

[0077] The opening can have any shape, such as a perfect circle, an ellipse (e.g., an ellipse having its major axis in a first direction), a square with rounded corners, a rectangle with rounded corners (e.g., a rectangle with rounded corners having its major side in a first direction), etc. For example, in a packaging body according to the present disclosure, when the first direction is the longitudinal direction and the opening is long in the first direction (e.g., an ellipse with its major axis in the first direction, or a rounded rectangle with its long side in the first direction), when the wet wipes are removed from the removal opening, the broken portion of the inner cover member is more likely to prevent the wipes from coming into direct contact with the opening.

[0078] In the above-mentioned packaging body, when the flap label is in an unopened state, it is preferable that at least a portion of the cellulose substrate layer is exposed at the cross-section of the opening, and when the flap label is in an unopened state, it is preferable that preferably 30% or more, more preferably 50% or more, even more preferably 70% or more, and even more preferably 90% or more of the total cross-sectional area of ​​the cellulose substrate layer is exposed at the cross-section of the opening. The above-mentioned term "exposed" means that the cross section of the cellulose substrate layer is not directly covered with a waterproof material such as a film.

[0079] The packaging body comprises a removal section including the opening, a flap label directly or indirectly covering the removal section from the outer surface side so that it can be repeatedly opened and closed, and an impermeable inner cover member directly or indirectly covering the removal section from the surface side. The removal portion includes the opening, and refers to the area where the flap label and the inner cover member overlap in the third direction, and the area between the flap label and the inner cover member.

[0080] As the material for the above-mentioned flap label, any material known in the art as a flap label can be used without limitation, and examples thereof include a film, a layer containing the above-mentioned hydrophilic fiber, and a laminate of a film. Furthermore, when the material of the flap label is a film, the flap label may be provided with a separation portion that enables the flap label to be separated from the main packaging body, so that the flap label can be separated and recycled.

[0081] In the package according to the present disclosure, the flap label may include a base member disposed on the package body side, and a lid member joined to the base member so as to be repeatedly opened and closed. In this case, the inner cover member may be fixed to the base member at the fixing portion, and the base member may be fixed to the lid member. This makes it possible for the package body to be protected when the lid member is opened and closed, and makes the opening and closing of the lid member less susceptible to the effects of wetting the cellulose-based base material layer, etc.

[0082] The flap label comprising the lid member and the base member may be fixed to the package body as an integral unit, for example, the lid member and the base member may be laminated, thereby simplifying the construction and manufacturing of the wet wipes package. In addition, after the flap label is first opened, the base member is preferably not fixed to the inner cover member and is preferably separated from the inner cover member, so that a broken portion of the inner cover member located inside the opening is not affected by the base member, and the wipes are prevented from coming into direct contact with the opening, preventing the medicinal solution from migrating to the cellulose-based base material layer and preventing the wipes from being difficult to remove.

[0083] The material of the cover member may be a film, a layer containing the above-mentioned hydrophilic fiber, etc. The material of the base member may be the same as the material of the outer cover member (inner cover member) described below.

[0084] The flap label may have an adhesive layer made of a pressure-sensitive adhesive on its inner surface (the surface on the inner cover member side) which is the surface on the inside of the packaging body, and the flap label may be directly or indirectly bonded to the packaging body by the adhesive layer so as to be repeatedly openable and closable. As a result, when the flap label is closed after starting to use the wet wipes, a portion of the inner cover member located inside the opening of the packaging body, for example, a part of the broken portion, can adhere to the flap label, making it difficult for the drug solution to transfer to the cellulose-based substrate.

[0085] Examples of the material for the impermeable inner cover member include films, for example, synthetic resin films, for example, polyolefins (eg, polyethylene, polypropylene, etc.), polyethylene terephthalate, polyester, polyamide, polyvinyl chloride, etc. The outer surface of the inner cover member, which is the surface on the flap label side, may be provided with an adhesive, i.e., an adhesive layer made of a pressure-sensitive adhesive, and the inner cover member may be fixed directly or indirectly to the package body by the adhesive layer. As a result, when the flap label is closed after starting to use the wet wipes, a portion of the inner cover member located inside the opening of the package body, for example, a part of the broken portion, can adhere to the cellulose-based substrate, the flap label, etc., on the cross section of the opening, making it difficult for the medicinal solution to transfer to the cellulose-based substrate.

[0086] The packaging body includes a fixing portion at the removal portion where the inner cover member is fixed to the flap label, whereby when the flap label is opened for the first time, the inner cover member associated with the fixing portion can be made to accurately follow the flap label. Fixation at the fixing portion may be achieved by an adhesive layer provided on the inner surface of the flap label and / or the outer surface of the inner cover member, by an adhesive layer disposed between the flap label and the inner cover member, or by fusion between the flap label and the inner cover member.

[0087] In this disclosure, the terms "fixed portion" and "fixed" mean that two or more members are in contact with each other so as not to separate during normal use of the packaging body according to the present disclosure. On the other hand, in the present disclosure, the term "joined" includes two or more components being in contact with each other so that they do not separate during normal use of the packaging body of the present disclosure, being in contact with each other so that they can be separated, and being in contact with each other so that they can be repeatedly separated.

[0088] In the package according to the present disclosure, the inner cover member may have a wall portion that stands toward the flap label and a top portion that contacts the flap label at the removal portion. Also, the inner cover member may be fixed to the flap label at at least a portion of the top portion to form the fixing portion. This makes it easier to achieve the effects of the present disclosure.

[0089] The package may have a weakened line for cutting the inner cover member at the outer edge of the fixing part of the inner cover member. This makes it easier to cut the inner cover member reliably outside the fixing part when the flap label is first opened, making it easier to remove the wipes. The weakened line may be arranged, for example, along the outer edge of the fixing part, and may be, for example, a non-through hole arranged continuously or intermittently along the outer edge of the fixing part, or a through hole arranged intermittently along the outer edge of the fixing part.

[0090] The inner cover member may have the weakened line on the outer side or the inner side of the outer edge of the apex, or may be provided so as to coincide with the outer edge of the apex, but it is preferable that the weakened line be provided on the inner side of the outer edge of the apex, so that after the start of use of the package, the part of the apex outside the weakened line is likely to come into contact with the flap label when the flap label is closed, and the wipes are prevented from coming into direct contact with the opening, and the transfer of the medicinal solution to the cellulose-based base material layer and the difficulty in removing the wipes are prevented.

[0091] The package according to the present disclosure may further include a water-impermeable outer cover member having an outer cover member opening between the flap label and the package body at the removal section. This makes it easier to protect the package body when the flap label is opened and closed, and makes the flap label less susceptible to the effects of wetting the cellulose-based base material layer, etc. The outer cover member opening may have any shape, for example, it may be the same shape as the opening of the package body, it may be larger than the opening, or it may be smaller than the opening.

[0092] The outer cover member opening can be of the same shape as the opening and can be arranged to coincide with the opening in the third direction. This allows, for example, the outer cover member opening and the opening to be formed simultaneously when manufacturing the package according to the present disclosure. In addition, the outer cover member can be easily separated from the inner cover member, and the broken portion of the inner cover member arranged inside the opening is not affected by the outer cover member, preventing the wipes from directly contacting the opening, and preventing the medicinal solution from migrating to the cellulose-based base material layer and preventing the wipes from being difficult to remove.

[0093] The outer cover member opening may be larger than the opening and may be disposed outside the opening in the third direction, which makes it easier for the outer cover member to be separated from the inner cover member and makes it easier to achieve the above-mentioned effects. Furthermore, the outer cover member opening may be smaller in shape than the opening and may be disposed more inward than the opening in the third direction, thereby preventing the wipe from directly contacting the opening.

[0094] The outer cover member is preferably not fixed to the inner cover member, and more preferably is separated from the inner cover member, so that a broken portion of the inner cover member located inside the opening is not affected by the outer cover member, and the wipes are prevented from directly contacting the opening, preventing the medicinal solution from migrating to the cellulose-based base material layer and preventing the wipes from being difficult to remove.

[0095] The material for the water-impermeable outer cover member may be the same as that for the water-impermeable inner cover member. The water-impermeable outer cover member may have a release surface on the flap label side, which allows the flap label to have excellent repetitive opening and closing properties.

[0096] In the removal section, the bonding strength between the flap label and the inner cover member at the fixing section is preferably higher than the bonding strength between the flap label and the outer cover member, so that when the flap label is first opened, the inner cover member can accurately have a break portion along the outer edge of the fixing section, and the flap label can accurately and repeatedly open and close the removal section.

[0097] In the package according to the present disclosure, the impermeable layer and the inner cover member may be configured as separate bodies, or may be integrally formed. By integrally forming the impermeable layer and the inner cover member, the wet wipes package has a simpler structure while retaining the medicinal solution before use, and after the start of use, the medicinal solution is less likely to migrate to the cellulose-based substrate, making it easy to remove the wipes. Furthermore, when the impermeable layer is composed of a plurality of layers, at least one of the impermeable layers can be formed integrally with the inner cover member.

[0098] Packages according to the present disclosure can be manufactured by methods known in the art. For example, the packaging body 1 according to the first embodiment can be manufactured as follows. A laminate is formed by sequentially stacking the flap label 23, the outer cover member 17, the packaging body 5 (having a sheet shape) having an opening 11, and the inner cover member 25. The laminate is passed through a pair of rolls or the like equipped with a line-of-weakness forming section, and in the removal section 21, the inner cover member 25 is fixed to the flap label 23 to form the fixing section 27 and the line of weakness 45. A plurality of wipes 3 are placed on the inner cover member 25 of the laminate with the line of weakness 45 formed therein, and the plurality of wipes 3 are impregnated with a chemical solution. A seal section and an end seal section 101 are formed in the laminate equipped with the plurality of wipes 3 and the chemical solution, and the package 1 is completed.

[0099] Also, for example, the packaging body 1 according to the third embodiment can be manufactured as follows. The outer cover member 17 and the cellulose-based base material layer 13 are laminated to form a first laminate, and the opening 11 and the outer cover member opening 19 are formed in the first laminate. The flap label 23, the first laminate having the opening 11 and the outer cover member opening 19, and the impermeable layer 15 (inner cover member 25) are laminated to form a second laminate. The second laminate is passed through a pair of rolls or the like equipped with a weakening line forming section, and the impermeable layer 15 (inner cover member 25) is fixed to the flap label 23 in the take-out section 21 to form the fixing section 27 and the weakening line 45. A plurality of wipes 3 are placed on the impermeable layer 15 (inner cover member 25) of the second laminate with the weakening line 45 formed, and the plurality of wipes 3 are impregnated with a chemical solution. A seal section and an end seal section 101 are formed in the second laminate equipped with the plurality of wipes 3 and the chemical solution, and the package 1 is completed.
