[0009] FIG. 1 is a view describing a packaging 1 according to the first embodiment. FIG. 2 is a view describing the packaging 1 according to the first embodiment. FIG. 3 is a view describing the packaging 1 according to the first embodiment. FIG. 4 is a view describing the packaging 1 according to the first embodiment. FIG. 5 is a view describing the packaging 1 according to the first embodiment. FIG. 6 is a view describing a packaging 1 according to the second embodiment. FIG. 7 is a view describing a packaging 1 according to the third embodiment. FIG. 8 is a view describing a packaging 1 according to the fourth embodiment. DESCRIPTION OF EMBODIMENTS

[0010] Specifically, the present disclosure relates to the following aspects.[Aspect 1]

[0011] A packaging of wet wipes, in which a plurality of wipes and a liquid agent are contained in an inner portion of a packaging body, wherein the packaging body has an inner surface and an outer surface and comprises an opening for dispensing the plurality of wipes, the packaging body comprises a cellulose-based substrate layer disposed on a side of the outer surface and a water-impermeable layer disposed on a side of the inner surface, the packaging comprises a dispensing part comprising the opening, a flap label resealably covering the dispensing part from the side of the outer surface, and an inner cover member having water impermeability that covers the dispensing part from the side of the inner surface, and the packaging comprises, in the dispensing part, a fixing portion where the inner cover member is fixed to the flap label.

[0012] In the packaging of wet wipes, the inner cover member covering the dispensing part of the wet wipes prior to use from the side of the inner surface is fixed to the flap label. Accordingly, the packaging has a simpler structure as compared with the sheet packaging disclosed in PTL 1, and leakage of a liquid agent from the packaging of wet wipes prior to use of the packaging can be inhibited.

[0013] After the start of use of the packaging of wet wipes, i.e., when the flap label is first unsealed, the inner cover member is torn near an outer edge of the fixing portion, resulting in the inner cover member having a tear portion along the outer edge of the fixing portion. At least a portion of the tear portion tends to be disposed inward relative to the opening of the packaging body.

[0014] The packaging body comprises a cellulose-based substrate layer, and thus tends to be more rigid as compared with a conventional packaging body comprising a plastic-based substrate layer. As a result, during the dispensing of a wet wipe, when the wipe comes into direct contact with the opening, the liquid agent impregnated in the wipe may transfer to the cellulose-based substrate layer, and the wipe may be caught on the opening and become difficult to be dispensed.

[0015] In the packaging of wet wipes, at least a portion of the tear portion of the inner cover member is disposed inward relative to the opening of the packaging body. Thus, the tear portion of the inner cover member disposed inward relative to the opening can inhibit a wipe from coming into direct contact with the opening, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe. If the cellulose-based substrate layer constitutes the outer surface of the packaging, when the liquid agent transfers to the cellulose-based substrate layer, the liquid agent may more easily volatilize from the outer surface of the packaging, and ultimately, retaining the liquid agent in the packaging of wet wipes may be more difficult.

[0016] From the foregoing, the packaging of wet wipes has a simple structure, can retain a liquid agent prior to use, and after start of use, inhibits transfer of the liquid agent to the cellulose-based substrate and facilitates dispensing of a wipe.[Aspect 2]

[0017] The packaging of wet wipes according to Aspect 1, wherein, in the dispensing part, an adhesive layer is provided on one or both of an inner side surface of the flap label and an outer side surface of the inner cover member.

[0018] In the packaging of wet wipes, an adhesive layer is provided on one or both of an inner side surface of the flap label and an outer side surface of the inner cover member.

[0019] If the adhesive layer is provided on an inner side surface of the flap label, when the flap label is closed after the start of use of wet wipes, a portion disposed inward relative to the opening of the packaging body, for example, a portion of the tear portion, of the inner cover member can adhere to the flap label. Thus, the liquid agent does not easily transfer to the cellulose-based substrate.

[0020] If the adhesive layer is provided on an outer side surface of the inner cover member, when the flap label is closed after start of use of wet wipes, a portion disposed inward relative to the opening of the packaging body, for example, a portion of the tear portion, of the inner cover member can adhere to the cellulose-based substrate or flap label at the cross-section of the opening. Thus, the liquid agent does not easily transfer to the cellulose-based substrate.[Aspect 3]

[0021] The packaging of wet wipes according to Aspect 1 or 2, wherein, in the dispensing part, the packaging further comprises an outer cover member having water impermeability that comprises 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.

[0022] The packaging of wet wipes comprises a predetermined outer cover member. Accordingly, when opening and closing the flap label, the packaging body is easily protected, and the flap label is less susceptible to conditions such as wetting of the cellulose-based substrate layer. In the packaging of wet wipes, the outer cover member is spaced apart from the inner cover member. Accordingly, the tear portion of the inner cover member disposed inward relative to the opening can inhibit a wipe from coming into direct contact with the opening without being affected by the outer cover member, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe.[Aspect 4]

[0023] The packaging of wet wipes according to Aspect 3, wherein the outer cover member has a release surface on the flap label side.

[0024] In the packaging of wet wipes, the outer cover member has a release surface on the flap label side. Thus, the flap label exhibits excellent resealability.[Aspect 5]

[0025] The packaging of wet wipes according to Aspect 3 or 4, wherein, in the dispensing part, attachment strength between the flap label and the inner cover member at the fixing portion is higher than attachment strength between the flap label and the outer cover member.

[0026] In the packaging of wet wipes, in the dispensing part, the attachment strength between the flap label and the inner cover member is higher than the attachment strength between the flap label and the outer cover member. Accordingly, in the packaging of wet wipes, when the flap label is first unsealed, the inner cover member can have a tear portion accurately formed along an outer edge of the fixing portion, and the flap label can accurately and repeatedly seal and unseal the dispensing part.[Aspect 6]

[0027] The packaging of wet wipes according to any one of Aspects 1 to 5, wherein the flap label comprises a base member disposed on a side of the packaging body and a lid member resealably attached to the base member, the base member and the lid member are integrally formed, and at the fixing portion, the inner cover member is fixed to the base member, and the base member is fixed to the lid member.

[0028] In the packaging of wet wipes, the flap label comprises a predetermined base member and a predetermined lid member that are integrally formed. Accordingly, when opening and closing the lid member, the packaging body is easily protected, and the opening and closing of the lid member is less susceptible to conditions such as wetting of the cellulose-based substrate layer. In the packaging of wet wipes, the structure and manufacture thereof can be simplified as compared with separately providing an outer cover member.[Aspect 7]

[0029] The packaging of wet wipes according to any one of Aspects 1 to 6, wherein the water-impermeable layer and the inner cover member are integrally formed.

[0030] In the packaging of wet wipes, the water-impermeable layer and the inner cover member are integrally formed. Accordingly, the packaging of wet wipes, while having a simpler structure, can retain a liquid agent prior to use, and after start of use, can inhibit transfer of the liquid agent to the cellulose-based substrate and facilitate dispensing of a wipe.[Aspect 8]

[0031] The packaging of wet wipes according to any one of Aspects 1 to 7, wherein, in the dispensing part, the inner cover member comprises a wall portion that stands upright toward the flap label and a top portion in contact with 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 fixing portion.

[0032] In the packaging of wet wipes, the inner cover member comprises a predetermined wall portion and a predetermined top portion. Thus, the effects of Aspect 1 are more easily exhibited.[Aspect 9]

[0033] The packaging for wet wipes according to Aspect 8, wherein the packaging is provided with a weakened line on an outer edge of the inner cover member constituting the fixing portion for detaching the inner cover member.

[0034] The packaging of wet wipes is provided with a predetermined weakened line on the inner cover member. Thus, when the flap label is first unsealed, the inner cover member can be easily and reliably detached on the outer side of the fixing portion, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe.[Aspect 10]

[0035] The packaging of wet wipes according to Aspect 9, wherein the inner cover member is provided with the weakened line on an inner side relative to an outer edge of the top portion.

[0036] In the packaging of wet wipes, the inner cover member is provided with a weakened line on an inner side relative to an outer edge of the top portion. Accordingly, a portion of the top portion on an outer side relative to the weakened line can inhibit a wipe from coming into direct contact with the opening, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe. When an adhesive layer is provided on one or both of an inner side surface of the flap label and an outer side surface of the inner cover member, the portion of the top portion on an outer side relative to the weakened line easily adheres to the flap label when the flap label is closed, and inhibits the transfer of the liquid agent to the cellulose-based substrate.[Aspect 11]

[0037] The packaging of wet wipes according to any one of Aspects 1 to 10, wherein the cellulose-based substrate layer comprises rayon.

[0038] In the packaging of wet wipes, the cellulose-based substrate layer comprises rayon. Thus, the packaging body is likely softer as compared with a cellulose-based substrate comprising pulp fibers. Therefore, during use of the packaging of wet wipes, noise caused by deformation of the packaging body are less likely to occur, and appearance of the packaging of wet wipes is more likely to have a luxurious feel.

[0039] The packaging of wet wipes of the present disclosure (hereinafter, may simply be referred to as "packaging") will be described in detail below.[First embodiment]

[0040] FIG. 1 to FIG. 5 are views for describing a packaging 1 for wet wipes according to one of the embodiments of the present disclosure (hereinafter, referred to as "first embodiment"). Specifically, FIG. 1 is an oblique view of the packaging 1. FIG. 2 is an oblique view showing the packaging 1 in a state of use. FIG. 3 is a plan view of the packaging 1. FIG. 4 is a partially enlarged end view in the vicinity of the dispensing part 21 on the IV-IV end surface in FIG. 3. FIG. 5 is a partially enlarged end view in the vicinity of the dispensing part 21 on the IV-IV end surface in FIG. 3, and shows the flap label 23 in an unsealed state.

[0041] The packaging 1 according to the first embodiment comprises a first direction D 1 , a second direction D 2 , and a third direction D 3 that are orthogonal to one another. The third direction D 3 is the vertical direction of the packaging 1, and is the direction in which a plurality of wipes 3 are stacked and the direction in which the plurality of wipes 3 are dispensed. The first direction D 1 and second direction D 2 are the longitudinal direction and width direction of the packaging 1, respectively.

[0042] In the packaging 1 according to the first embodiment, the plurality of wipes 3 and the liquid agent (not illustrated) are contained in an inner portion of the packaging body 5. Each of the plurality of wipes 3 is folded to be stacked in the third direction D 3 . However, this is not a characteristic feature according to the present disclosure. Thus, the detailed description thereof is omitted.

[0043] In the packaging 1 according to the first embodiment, the packaging body 5 is formed into a cylindrical shape by providing a sheet-like packaging body 5 having a first direction D 1 and a second direction D 2 with a seal portion (not illustrated) at the end portions in the second direction D 2 , and formed into a bag shape by providing both ends in the first direction D 1 with an end seal portion 101.

[0044] The packaging body 5 has an inner surface 7 and an outer surface 9 and comprises an opening 11 for dispensing a plurality of wipes 3. The packaging body 5 comprises a cellulose-based substrate layer 13 disposed on the outer surface 9 side and a water-impermeable layer 15 disposed on the inner surface 7 side. The cellulose-based substrate layer 13 constitutes the outer surface 9 of the packaging body 5, and the water-impermeable layer 15 constitutes the inner surface 7 of the packaging body 5.

[0045] The packaging 1 comprises a dispensing part 21 comprising an opening 11. The packaging 1 comprises an outer cover member 17 covering the dispensing part 21 from the outer surface 9 side. The outer cover member 17 comprises 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 D 3 .

[0046] The packaging 1 comprises a flap label 23 resealably covering the dispensing part 21 from the outer surface 9 side via the outer cover member 17. The flap label 23 comprises a flap label inner side surface 31 on the inner surface 7 side and a flap label outer side surface 33 on the outer surface 9 side, and comprises an adhesive layer (not illustrated) on the flap label inner side surface 31. The outer cover member 17 has, on the flap label 23 side, a release surface to which a release agent is applied. Consequently, the flap label 23 is resealably attached, specifically, adhered, to the outer cover member 17.

[0047] The packaging 1 comprises an inner cover member 25 having water impermeability that covers the dispensing part 21 from the inner surface 7 side. The inner cover member 25 comprises an inner cover member inner side surface 35 disposed on the inner surface 7 side and an inner cover member outer side surface 37 disposed on the outer surface 9 side, and comprises, on the inner cover member outer side surface 37, an adhesive layer (not illustrated) to which an adhesive agent is applied.

[0048] The packaging 1 comprises, in the dispensing part, a fixing portion 27 where the inner cover member 25 is fixed to the flap label 23.

[0049] In the dispensing part 21, the inner cover member 25 comprises a wall portion 41 that stands upright toward the flap label 23 and a top portion 43 in contact with the flap label 23. In a portion of the top portion 43, the inner cover member 25 is fixed to the flap label 23 to form the fixing portion 27. The packaging 1 comprises, on the outer edge (not illustrated) of the fixing portion 27, a weakened line 45 for detaching the inner cover member 25. The weakened line 45 is formed by cutting the inner cover member 25 from the inner cover member inner side surface 35 side so as to circle the outer edge of the fixing portion 27 and so as not to penetrate the inner cover member 25. The weakened line 45 is disposed inward relative to an outer edge of the top portion 43.

[0050] When the flap label 23 is first unsealed, the inner cover member 25 is torn along the weakened line 45 that circles the outer edge of the fixing portion 27, and a portion of the inner cover member 25 on an inner side relative to 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 on an outer side relative to the weakened line 45, the inner cover member 25 comprises a wall portion 41 having a tear portion along the outer edge of the fixing portion 27. The wall portion 41 having a tear portion is disposed inward relative to the opening 11 of the packaging body 5.

[0051] The packaging body 5 comprises a cellulose-based substrate layer 13, and tends to be more rigid as compared with a conventional packaging body comprising a plastic-based substrate layer. As a result, during the dispensing of a wipe 3, when the wipe 3 comes into direct contact with the opening 11, the liquid agent impregnated in the wipe 3 may transfer to the cellulose-based substrate layer 13, and the wipe 3 may be caught on the opening 11 and become difficult to be dispensed.

[0052] In the packaging 1 for wet wipes, a wall portion 41 having a tear portion is disposed inward relative to the opening 11 of the packaging body 5. Thus, the wall portion 41 having a tear portion can inhibit a wipe 3 from coming into direct contact with the opening 11, and can inhibit the transfer of a liquid agent to the cellulose-based substrate layer 13 and the difficulty in dispensing the wipe 3.

[0053] In the dispensing part 21, the attachment strength between the flap label 23 and the inner cover member 25 at the fixing portion 27 is higher than the attachment strength between the flap label 23 and the outer cover member 17. Consequently, when the flap label 23 is first unsealed, the inner cover member 25 can have a tear portion accurately formed along an outer edge of the fixing portion 27, and the flap label 23 can accurately and repeatedly seal and unseal the dispensing part 21.[Second embodiment]

[0054] FIG. 6 is a view for describing the packaging 1 for wet wipes according to another embodiment of the present disclosure (hereinafter, referred to as "second embodiment"). FIG. 6 is a view that corresponds to FIG. 4 of the first embodiment. The packaging 1 according to the second embodiment will be described with a focus on parts that are different from the packaging 1 according to the first embodiment, and descriptions of the same parts will be omitted.

[0055] The packaging 1 according to the second embodiment comprises a dispensing part 21 comprising an opening 11, a flap label 23 resealably covering the dispensing part 21 from an outer surface 9 side, and an inner cover member 25 having water impermeability covering the dispensing part 21 from an inner surface 7 side.

[0056] The flap label 23 comprises a base member 51 and a lid member 53 resealably attached to the base member 51. The flap label 23 is not only disposed over the dispensing part 21 but also beyond the dispensing part 21 in the first direction (not illustrated) and the second direction D 2 .

[0057] The base member 51 and lid member 53 constituting the flap label 23 are integrally formed or laminated. Specifically, on the inner side surface (not illustrated) of the base member 51, a first adhesive layer (not illustrated) is provided by a first adhesive agent, and the base member 51 is fixed to the cellulose-based substrate layer 13 of the packaging body 5. The outer side surface (not illustrated) of the base member 51 constitutes a release surface having releasability. On the inner side surface (not illustrated) of the lid member 53, a second adhesive layer (not illustrated) is provided by a second adhesive agent, and the lid member is resealably attached to the outer side surface (release surface) of the base member 51. Since the second adhesive agent has lower adhesion relative to the first adhesive agent and the outer side surface of the base member 51 is provided with a release surface, when opening and closing the lid member 53, the base member 51 can remain fixed to the cellulose-based substrate layer 13.

[0058] The inner cover member 25 comprises a wall portion 41 that stands upright toward the flap label 23 and a top portion 43 in contact with the flap label 23. In a portion 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 the fixing portion 27. The packaging 1 comprises, on the outer edge of the fixing portion 27, a weakened line 45 for detaching the inner cover member 25 and base member 51. Specifically, the weakened line 45 is formed by cutting the inner cover member 25 and base member 51 from the inner cover member 25 side so as to circle the outer edge of the fixing portion 27 and so as to penetrate the inner cover member 25 but not penetrate the base member 51.

[0059] Consequently, when the flap label 23 is first unsealed, the inner cover member 25 is easily and reliably detached on the outer side of the fixing portion 27, facilitating the dispensing of a wipe.[Third embodiment]

[0060] FIG. 7 is a view for describing the packaging 1 for wet wipes according to another embodiment of the present disclosure (hereinafter, referred to as "third embodiment"). FIG. 7 is a view that corresponds to FIG. 4 of the first embodiment. The packaging 1 according to the third embodiment will be described with a focus on parts that are different from the packaging 1 according to the first embodiment, and descriptions of the same parts will be omitted.

[0061] In the packaging 1 according to the third embodiment, the packaging 1 comprises a dispensing part 21 comprising an opening 11, a flap label 23 resealably covering the dispensing part 21 from an outer surface 9 side, and an inner cover member 25 having water impermeability covering the dispensing part 21 from an inner surface 7 side. The packaging 1 comprises, in the dispensing part 21, a fixing portion 27 where the inner cover member 25 is fixed to the flap label 23.

[0062] A water-impermeable layer 15 and the inner cover member 25 are integrally formed. Consequently, the packaging 1 according to the third embodiment can have an even simpler structure.[Fourth embodiment]

[0063] FIG. 8 is a view for describing the packaging 1 for wet wipes according to another embodiment of the present disclosure (hereinafter, referred to as "fourth embodiment"). FIG. 8 is a view that corresponds to FIG. 4 of the first embodiment. The packaging 1 according to the fourth embodiment will be described with a focus on parts that are different from the packaging 1 according to the first embodiment, and descriptions of the same parts will be omitted.

[0064] In the packaging 1 according to the fourth embodiment, the flap label 23 is resealably attached directly to a cellulose-based substrate layer 13 constituting the packaging body 5. Consequently, the packaging 1 according to the fourth embodiment can have an even simpler structure.

[0065] The packaging of wet wipes according to the present disclosure can have a first direction, a second direction, and a third direction that are orthogonal to one another.

[0066] The third direction is the direction in which the plurality of wipes are stacked, and the first direction and the second direction can be planar directions of the plurality of wipes. For example, the first direction and the second direction can be the longitudinal direction and the transverse direction, respectively, of the packaging.

[0067] In the packaging of wet wipes according to the present disclosure, the plurality of wipes and the liquid agent are contained in an inner portion of the packaging body.

[0068] The plurality of wipes need only to be those used as substrates for wet wipes in the pertinent technical field and are not particularly limited, and include fabric, for example, nonwoven fabric, woven fabric, and knitted fabric.

[0069] The fabric can comprise hydrophilic fibers, hydrophobic fibers, and heat-fusible fibers.

[0070] The hydrophilic fibers include cellulose-based fibers, for example, natural cellulose fibers, regenerated cellulose fibers, purified cellulose fibers, and semi-synthetic cellulose fibers.

[0071] The natural cellulose fibers include plant fibers, for example, pulp fibers, seed fibers (for example, cotton fibers), bast fibers (for example, hemp), leaf fibers (for example, Manila hemp), and fruit fibers (for example, palm).

[0072] The pulp fibers include pulp fibers known in the pertinent technical field, and for example, include wood pulp fibers and non-wood pulp fibers. Examples of the wood pulp fibers include softwood pulp fibers and hardwood pulp fibers. Examples of the non-wood pulp fibers include straw pulp fibers, bagasse pulp fibers, reed pulp fibers, kenaf pulp fibers, mulberry pulp fibers, bamboo pulp fibers, hemp pulp fibers, and cotton pulp fibers (for example, cotton linter fibers).

[0073] The pulp fibers may consist of waste paper or recycled pulp fibers.

[0074] The cotton fibers include Gossypium hirsutum cotton fibers (for example, upland cotton), Gossypium barbadense cotton fibers, Gossypium arboreum cotton fibers, and Gossypium helbaceum cotton fibers.

[0075] The cotton fibers can be organic cotton fibers or Pre Organic Cotton (trademark) fibers.

[0076] Organic cotton fibers refer to cotton certified by GOTS (Global Organic Textile Standard).

[0077] The regenerated cellulose fibers include fibers of rayon, for example, viscose rayon obtained from viscose, polynosic and modal fibers, and fibers of cuprammonium rayon (also referred to as "cupra") obtained from a cuprammonium salt solution of cellulose.

[0078] The purified cellulose fibers include lyocell fibers, specifically those obtained by dissolving pulp in an aqueous solution of N-methylmorpholine N-oxide to prepare a spinning dope and extruding the dope into a dilute solution of N-methylmorpholine N-oxide to form fibers. The purified cellulose is commercially available, for example, under the trade name Tencel (trademark).

[0079] The semi-synthetic fibers include fibers of semi-synthetic cellulose, for example, acetate fibers, for example, triacetate or diacetate fibers.

[0080] The hydrophobic fibers include those commonly used in the pertinent technical field, for example, synthetic fibers. The synthetic fibers include those comprising a single component, for example, monofilaments, or those comprising a plurality of components, for example, composite fibers. The synthetic fibers can consist of biomass plastics or recycled fibers.

[0081] Examples of the components include polyolefin-based polymers, for example, polyethylene and polypropylene; polyester-based polymers, for example, terephthalate-based polymers, for example, polyethylene terephthalate (PET), polybutylene terephthalate, and polypentylene terephthalate; polyamide-based polymers, for example, nylon 6 and nylon 6,6; acrylic polymers; polyacrylonitrile-based polymers; and modified products thereof.

[0082] The hydrophobic fibers can include water-repellent cellulose-based fibers imparted with water repellency by treating the cellulose-based fibers described above with a water-repelling agent. The cellulose-based fibers described above, for the purpose of differentiation, may be referred to as hydrophilic cellulose-based fibers.

[0083] The water-repellent cellulose-based fibers have effects such as (i) inhibiting portions of adjacent wet wipes from adhering to one another and facilitating separation between wet wipes, and (ii) being biodegradable and capable of reducing environmental burden.

[0084] The water-repellent cellulose-based fibers are disclosed in, for example, Japanese Unexamined Patent Publication (Kokai) No. 2002-266241, Japanese Unexamined Patent Publication (Kokai) No. 2003-20570, Japanese Unexamined Patent Publication (Kokai) No. 2019-65443, and Japanese Unexamined Patent Publication (Kokai) No. 2022-58301, and are commercially available as, for example, Eco Repellas (trade name, water-repellent viscose rayon) manufactured by Daiwabo Rayon Co., Ltd. and Olea (trade name, water-repellent viscose rayon) manufactured by Kelheim Fibres GmbH.

[0085] When the fabric comprises the heat-fusible fibers and by heat fusion between heat-fusible fibers or heat fusion between heat-fusible fibers and cellulose fibers (water-repellent cellulose-based fibers and hydrophilic cellulose-based fibers), the strength of the fabric, and ultimately, the wet strength of the wet wipe, can be increased. When the heat-fusible fibers are heat-fused to one another, the strength of the fabric, and ultimately, the wet strength of the wet wipe, can be further increased.

[0086] Heat-fusible fibers used in the pertinent technical field, specifically, fibers comprising a thermoplastic resin having a low melting point and a thermoplastic resin having a high melting point, can be adopted as the heat-fusible fibers without limitation. In order to fuse the heat-fusible fibers to one another, it is preferable that at least the surface comprise a thermoplastic resin having a low melting point, such as a polyethylene resin or a low-melting polypropylene. Examples of the heat-fusible fibers include single-component fibers of a polyethylene resin; single-component fibers of a polypropylene resin, core-sheath-type composite synthetic fibers in which the core portion consists of a polyethylene terephthalate resin and the sheath portion consists of a polyethylene resin; core-sheath-type composite synthetic fibers in which the core portion consists of a polypropylene resin and the sheath portion consists of a polyethylene resin; core-sheath-type composite synthetic fibers in which the core portion consists of a high-melting polypropylene resin and the sheath portion consists of a low-melting polypropylene resin; side-by-side-type composite synthetic fibers consisting of a polyethylene terephthalate resin and a polyethylene resin; and side-by-side-type composite synthetic fibers consisting of a polypropylene resin and a polyethylene resin.

[0087] The heat-fusible fibers are preferably heat-fusible fibers having biodegradability. Consequently, the fabric, and ultimately, the wet wipe, is likely to have biodegradability.

[0088] Examples of the thermoplastic resin having a low melting point that constitutes the heat-fusible fibers having biodegradability 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.

[0089] Examples of the thermoplastic resin having a high melting point that constitutes the heat-fusible fibers having biodegradability include polylactic acid, polyhydroxybutyrate, polyglycolic acid, and cellulose acetate.

[0090] The heat-fusible fibers can consist of biomass plastics or recycled heat-fusible fibers.

[0091] For example, any nonwoven fabric (for example, spunlace nonwoven fabric, air-through nonwoven fabric, spunbond nonwoven fabric, or point-bonded nonwoven fabric) manufactured 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-punching method, or a felting method, can be adopted as the nonwoven fabric. Spunlace nonwoven fabric, which has high wet strength, is preferable.

[0092] The plurality of wipes can be stacked in the third direction in a state known in the pertinent technical field.

[0093] For example, the plurality of wipes can be stacked vertically in the third direction, wherein the upper end portion of a lower wet wipe positioned on a lower side and the lower end portion of an upper wet wipe adjacent above the lower wet wipe can be disposed so as to overlap one another, such that the upper end portion of the lower wet wipe is positioned above the lower end portion of the upper wet wipe.

[0094] Liquid agents generally used in the pertinent technical field can be adopted as the liquid agent in accordance with the application of the wet wipes.

[0095] For example, the liquid agent can comprise water; a water-soluble solvent, for example, an alcohol, for example, ethanol; an antibacterial agent; or an additive.

[0096] In the packaging according to the present disclosure, from the viewpoint of the object, the liquid agent comprises water, preferably at 50% by mass or more, more preferably at 60% by mass or more, even more preferably at 70% by mass or more, still more preferably 80% by mass or more, and still even more preferably at 90% by mass or more.

[0097] In the packaging according to the present disclosure, the packaging body has an inner surface and an outer surface and comprises an opening for dispensing the plurality of wipes. The inner surface refers to a surface of the packaging body on which the plurality of wipes and the liquid agent are retained.

[0098] The packaging body comprises a cellulose-based substrate layer disposed on the side of the outer surface and a water-impermeable layer disposed on the side of the inner surface, and can comprise additional layers.

[0099] The cellulose-based substrate layer includes layers comprising the hydrophilic fibers described above, for example, pulp fibers or regenerated cellulose fibers (for example, rayon). The cellulose-based substrate layers, for example, can have a thickness of 0.05 to 0.5 mm.

[0100] When the cellulose-based substrate layer comprises pulp fibers, rigidity of the packaging body (packaging) increases, and when the packaging according to the present disclosure is contained in a storage container for use, the packaging body is less likely to be crushed.

[0101] When the cellulose-based substrate layer comprises pulp fibers, rigidity of the packaging body is likely to increase, and thus a wipe is easily caught on the opening. In the packaging according to the present disclosure, the tear portion of the inner cover member can inhibit a wipe from coming into direct contact with the opening, and can inhibit the difficulty in dispensing a wipe.

[0102] When the cellulose-based substrate layer comprises pulp fibers, for example, 50% by mass or more of pulp fibers, the packaging body can be discarded as paper waste.

[0103] When the cellulose-based substrate layer comprises regenerated cellulose fibers (for example, rayon), purified cellulose fibers, or semi-synthetic fibers, noise caused by deformation of the packaging body is less likely to occur during use of the packaging of wet wipes, and the packaging of wet wipes is more likely to have a luxurious feel.

[0104] The water-impermeable layer is not particularly limited as long as water does not pass through, and for example, includes a barrier layer, a sealant layer, and combinations thereof.

[0105] Examples of materials for the barrier layer include resin films made of polyethylene terephthalate or nylon on which alumina or silica is vapor-deposited.

[0106] Examples of materials for the sealant layer include thin films having heat sealability, such as those of low-density polyethylene (LDPE) or cast polypropylene (CPP).

[0107] The opening can have any shape, and for example, can be a perfect circle, an ellipse (for example, an ellipse having a major axis in the first direction), a rounded-corner square, and a rounded-corner rectangle (for example, a rounded-corner rectangle having a long side in the first direction).

[0108] For example, in the packaging according to the present disclosure, when the first direction is the longitudinal direction, and the opening is long in the first direction (for example, an ellipse having a major axis in the first direction or a rounded-corner rectangle having a long side in the first direction), when dispensing a wet wipe from the dispensing outlet, the tear portion of the inner cover member more easily inhibits the wipe from coming into direct contact with the opening.

[0109] In the packaging body, it is preferable that, when the flap label is in an unopened state, at the cross-section of the opening, at least a portion of the cellulose substrate layer be exposed, and it is preferable that, when the flap label is in an unopened state, at the cross-section of the opening, preferably 30% or more, more preferably 50% or more, even more preferably 70% or more, and still even more preferably 90% or more of the total cross-sectional area of the cellulose substrate layer be exposed.

[0110] Being exposed means that a cross-section of the cellulose substrate layer is not directly covered with a waterproof material such as a film.

[0111] The packaging comprises a dispensing part comprising the opening; a flap label, directly or indirectly, resealably covering the dispensing part from the side of the outer surface; and an inner cover member having water impermeability that directly or indirectly covers the dispensing part from the side of the inner surface.

[0112] The dispensing part comprises the opening, and refers to the region where the flap label and the inner cover member overlap in the third direction and the region between the flap label and the inner cover member.

[0113] Flap labels known in the pertinent technical field can be adopted as the material for the flap label without limitation, and for example, include films and laminates of a layer comprising the hydrophilic fibers described above and a film.

[0114] When the material for the flap label is a film, the flap label may be provided with a detaching portion that allows the flap label to be detached from the packaging body so that the flap label can be separated and recycled.

[0115] In the packaging according to the present disclosure, the flap label can comprise a base member disposed on a side of the packaging body and a lid member resealably attached to the base member. In this case, at the fixing portion, the inner cover member can be fixed to the base member, and the base member can be fixed to the lid member. Consequently, in the packaging, when opening and closing the lid member, the packaging body is easily protected, and the opening and closing of the lid member is less susceptible to conditions such as wetting of the cellulose-based substrate layer.

[0116] The flap label comprising the lid member and the base member may have the lid member and the base member integrally fixed to the packaging body. For example, the lid member and the base member may be laminated. Consequently, the structure and manufacture of the packaging of wet wipes are simplified.

[0117] After the flap label is first unsealed, the base member is preferably not fixed to the inner cover member, and the base member is preferably spaced apart from the inner cover member. Consequently, the tear portion of the inner cover member disposed inward relative to the opening can inhibit a wipe from coming into direct contact with the opening without being affected by the outer cover member, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe.

[0118] Materials for the lid member include films and layers comprising the hydrophilic fibers described above. Materials for the base member include the same materials as those of the outer cover member (inner cover member) described below.

[0119] The inner side surface (surface on the inner cover member side) of the flap label, which is the surface on the inner portion side of the packaging body, may be provided with an adhesive layer formed of an adhesive agent, i.e., a pressure-sensitive adhesive, wherein the flap label may be, directly or indirectly, resealably attached to the packaging body by the adhesive layer. Consequently, after start of use of wet wipes, when the flap label is closed, the portion disposed inward relative to the opening of the packaging body, for example, a portion of the tear portion, of the inner cover member can adhere to the flap label. Thus, the liquid agent does not easily transfer to the cellulose-based substrate.

[0120] Examples of materials for the inner cover member having water impermeability include films, for example, films of synthetic resins, for example, polyolefins (for example, polyethylene and polypropylene), polyethylene terephthalate, polyester, polyamide, and polyvinyl chloride.

[0121] On the outer side surface of the inner cover member, which is the surface on the flap label side, an adhesive layer formed of an adhesive agent, i.e., a pressure-sensitive adhesive agent, may be provided, wherein the inner cover member may be directly or indirectly fixed to the packaging body by the adhesive layer. Consequently, after start of use of wet wipes, when the flap label is closed, a portion disposed inward relative to the opening of the packaging body, for example, a portion of the tear portion, of the inner cover member can adhere to the cellulose-based substrate at the cross-section of the opening. Thus, the liquid agent does not easily transfer to the cellulose-based substrate.

[0122] The packaging comprises, in the dispensing part, a fixing portion where the inner cover member is fixed to the flap label. Consequently, when the flap label is first unsealed, the inner cover member corresponding to the fixing portion can accurately follow the flap label.

[0123] The fixing at the fixing portion may be carried out by an adhesive layer provided on the inner side surface of the flap label and / or the outer side surface of the inner cover member, may be carried out by an adhesive layer disposed between the flap label and the inner cover member, and may be carried out by fusion bonding between the flap label and the inner cover member.

[0124] In the present disclosure, the terms "fixing portion" and "fixed" refer to two or more members in contact so as not to separate during normal use of the packaging according to the present disclosure.

[0125] In the present disclosure, the term "attached" includes a state in which two or more members are in contact so as not to separate during normal use of the packaging according to the present disclosure, a state in which the two or more members are in contact so as to be separable, and a state in which the two or more members are in contact so as to be repeatedly separable.

[0126] In the packaging according to the present disclosure, the inner cover member can comprise, in the dispensing part, a wall portion that stands upright toward the flap label and a top portion in contact with the flap label. The inner cover member, in at least a portion of the top portion, can be fixed to the flap label to form the fixing portion. Consequently, the effects according to the present disclosure are easily and accurately exhibited.

[0127] The packaging can be provided with a weakened line for detaching the inner cover member on the outer edge of the fixing portion of the inner cover member. Consequently, when the flap label is first unsealed, the inner cover member is easily and reliably detached on the outer side of the fixing portion, and a wipe is easily dispensed. The weakened line, for example, can be disposed along the outer edge of the fixing portion, and for example, can be non-penetrating holes disposed continuously or intermittently along the outer edge of the fixing portion, or penetrating holes disposed intermittently along the outer edge of the fixing portion.

[0128] The inner cover member can be provided with the weakened line on an outer side or an inner side relative to the outer edge of the top portion or coinciding with the outer edge of the top portion, but is preferably provided on an inner side relative to the outer edge of the top portion. Consequently, after start of use of the packaging, a portion of the top portion on an outer side relative to the weakened line is likely to come into contact with the flap label when the flap label is closed, a wipe can be inhibited from coming into direct contact with the opening, and the liquid agent being transferred to the cellulose-based substrate layer and the difficulty in dispensing a wipe can be inhibited.

[0129] The packaging according to the present disclosure can further comprise, in the dispensing part, an outer cover member having water impermeability that comprises an outer cover member opening between the flap label and the packaging body. Consequently, when opening and closing the flap label, the packaging body is more easily protected, and the flap label is less susceptible to conditions such as wetting of the cellulose-based substrate layer. The outer cover member opening can have any shape, and for example, can have the same shape as the opening provided in the packaging body, can have a shape larger than the opening, or can have a shape smaller than the opening.

[0130] The outer cover member opening can have the same shape as the opening, and can be disposed to coincide with the opening in the third direction. Consequently, for example, when manufacturing the packaging according to the present disclosure, the outer cover member opening and the opening can be formed simultaneously. The outer cover member is more easily spaced apart from the inner cover member, the tear portion of the inner cover member disposed inward relative to the opening can inhibit a wipe from coming into direct contact with the opening without being affected by the outer cover member, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe.

[0131] The outer cover member opening can have a shape larger than the opening, and can be disposed outward relative to the opening in the third direction. Consequently, the outer cover member is more easily spaced apart from the inner cover member, and the effects described above are more easily achieved.

[0132] The outer cover member opening can have a shape smaller than the opening, and can be disposed inward relative to the opening in the third direction. Consequently, a wipe can be inhibited from coming into direct contact with the opening.

[0133] The outer cover member is preferably not fixed to the inner cover member, and is more preferably spaced apart from the inner cover member. Consequently, the tear portion of inner cover member disposed inward relative to the opening can inhibit a wipe from coming into direct contact with the opening without being affected by the outer cover member, and can inhibit the transfer of the liquid agent to the cellulose-based substrate layer and the difficulty in dispensing a wipe.

[0134] The same materials as those of the inner cover member having water impermeability can be adopted as the material for the outer cover member having water impermeability.

[0135] The outer cover member having water impermeability can have a release surface on the flap label side. Consequently, the flap label exhibits excellent resealability.

[0136] In the dispensing part, the attachment strength between the flap label and the inner cover member at the fixing portion is preferably higher than the attachment strength between the flap label and the outer cover member. Consequently, when the flap label is first unsealed, the inner cover member can have a tear portion accurately formed along an outer edge of the fixing portion, and the flap label can accurately and repeatedly seal and unseal the dispensing part.

[0137] In the packaging according to the present disclosure, the water-impermeable layer and the inner cover member may constitute separate bodies, or may be integrally formed. By forming the water-impermeable layer and the inner cover member integrally, the packaging of wet wipes, while having a simpler structure, can retain the liquid agent prior to use, and after start of use, can inhibit the transfer of the liquid agent to a cellulose-based substrate and facilitate dispensing of a wipe.

[0138] When the water-impermeable layer is composed of a plurality of layers, at least one layer within the water-impermeable layer can be integrally formed with the inner cover member.

[0139] The packaging according to the present disclosure can be manufactured by a known method in the pertinent technical field.

[0140] For example, the packaging 1 according to the first embodiment can be manufactured as follows.

[0141] A flap label 23, an outer cover member 17, a packaging body 5 (having a sheet form) having an opening 11, and an inner cover member 25 are layered in this order to form a layered body. The layered body is passed through a pair of rolls provided with a weakened line forming portion, whereby, in the dispensing part 21, the inner cover member 25 is fixed to the flap label 23 to form a fixing portion 27, and a weakened line 45 is formed. On the inner cover member 25 of the layered body on which the weakened line 45 has been formed, a plurality of wipes 3 are placed, and the plurality of wipes 3 are impregnated with a liquid agent. Seal portions and end seal portions 101 are formed on the layered body provided with the plurality of wipes 3 and the liquid agent, thereby completing a packaging 1.

[0142] For example, the packaging 1 according to the third embodiment can be manufactured as follows.

[0143] An outer cover member 17 and a cellulose-based substrate layer 13 are layered to form a first layered body, and an opening 11 and an outer cover member opening 19 are formed in the first layered body. A flap label 23, the first layered body having the opening 11 and the outer cover member opening 19, and a water-impermeable layer 15 (inner cover member 25) are layered to form a second layered body. The second layered body is passed through a pair of rolls provided with a weakened line forming portion, whereby, in the dispensing part 21, the water-impermeable layer 15 (inner cover member 25) is fixed to the flap label 23 to form a fixing portion 27, and a weakened line 45 is formed. On the water-impermeable layer 15 (inner cover member 25) of the second layered body on which the weakened line 45 has been formed, a plurality of wipes 3 are placed, and the plurality of wipes 3 are impregnated with a liquid agent. Seal portions and end seal portions 101 are formed on the second layered body provided with the plurality of wipes 3 and the liquid agent, thereby completing a packaging 1.REFERENCE SIGNS LIST
