[0008] Specifically, the present disclosure relates to the following aspects: [Aspect 1] A wet wipes package comprising a package body housing a plurality of wipes and a liquid medicine, a removal section, and a flap label covering the removal section so as to be repeatedly openable and closable, The packaging body has an inner surface and an outer surface, and is provided with a cellulose-based base material layer disposed on the outer surface side and an impermeable layer disposed on the inner surface side, The cellulosic base material layer has a base material layer opening at the removal portion, the impermeable layer is provided with an impermeable layer opening portion provided with an impermeable layer opening or an impermeable layer opening forming portion forming the impermeable layer opening at the removal portion, In a plan view in the removal direction of the removal portion, an outer edge of the impermeable layer opening is disposed inward from an outer edge of the base material layer opening. A package for wet wipes comprising:

[0009] In the above-mentioned wet wipes packaging, the impermeable layer constituting the packaging body has a predetermined impermeable layer opening before use, and therefore has a simpler structure than the sheet packaging body disclosed in Patent Document 1. In addition, before starting to use the wet wipes packaging, the medicinal solution can be retained to a certain extent by preventing the medicinal solution from reaching the cellulose-based substrate layer, compared to a packaging in which the outer edge of the impermeable layer opening is positioned at the same level as or outside the outer edge of the substrate layer opening.

[0010] Since the above-mentioned package body includes a cellulose-based base layer, it tends to be harder than a conventional package body including a plastic base layer. As a result, when removing the wipe, if the wipe comes into direct contact with the opening of the base layer, the medicinal solution impregnated in the wipe may transfer to the cellulose-based base layer, and the wipe may get caught in the opening of the base layer, making it difficult to remove.

[0011] In relation to this, in the wet wipes packaging, the impermeable layer inner part of the impermeable layer, which is arranged inside the outer edge of the base layer opening, is arranged inside the outer edge of the base layer opening. Therefore, compared to a packaging in which the outer edge of the impermeable layer opening is arranged on the same side as or outside the outer edge of the base layer opening, the impermeable layer inner part prevents the wipe from directly contacting the base layer opening, and can prevent the medicinal solution from migrating to the cellulose-based base layer and the wipe from being difficult to remove. In addition, when the cellulose-based base layer constitutes the outer surface of the packaging, if the medicinal solution migrates to the cellulose-based base layer, the medicinal solution is likely to volatilize from the outer surface of the packaging, which may make it difficult for the wet wipes packaging to retain the medicinal solution.

[0012] As described above, the packaging for the wet wipes has a simple structure, and after use, the medicinal solution is less likely to migrate into the cellulose-based base material, and the wipes are easy to remove.

[0013] In this specification, "inward" means that a certain member is disposed closer to the center than the target member when viewed in a plan view in the removal direction of the removal portion. For example, when the outer edge of the impermeable layer opening is positioned inwardly of the outer edge of the base material layer opening, it means that when viewed in a plan view in the removal direction of the removal section, the outer edge of the impermeable layer opening is positioned closer to the center of the base material layer opening than the outer edge of the base material layer opening.

[0014] [Aspect 2] A wet wipes package according to claim 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 impermeable layer in 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 water-impermeable layer. When an adhesive layer is provided on the inner surface of the flap label, at least a portion of the inner part of the impermeable layer can adhere to the flap label before and after use of the packaging body begins, making it difficult for the chemical solution to migrate into the cellulose-based substrate.

[0016] In addition, when an adhesive layer is provided on the outer surface of the impermeable layer, before and after use of the packaging body is started, at least a portion of the inner part of the impermeable layer can adhere to the cellulose-based substrate and / or flap label, etc. at the cross section of the opening of the substrate layer, making it difficult for the chemical solution to transfer to the cellulose-based substrate.

[0017] In this specification, the terms "inner surface" and "outer surface" are terms that define the two surfaces that the object has in the removal direction of the removal section, and of the two surfaces that the object has, the surface facing the inner surface of the packaging body and the surface facing the outer surface of the packaging body are referred to as the "inner surface" and the "outer surface", respectively.

[0018] [Aspect 3] A packaging body for wet wipes according to aspect 1 or 2, wherein in the removal section, the packaging body further comprises an impermeable outer cover member between the flap label and the packaging body, the outer cover member opening having an outer cover member opening or an outer cover member opening forming portion capable of forming the outer cover member opening.

[0019] The wet wipes packaging includes a predetermined outer cover member, which makes it easier to protect the packaging body when the flap label is opened and closed, and also makes the flap label less susceptible to the effects of wetting the cellulosic base material layer, etc.

[0020] [Aspect 4] A packaging body for wet wipes according to aspect 3, wherein, in the plan view, at least a portion of an outer edge of the outer cover member opening is positioned inward from an outer edge of the base material layer opening.

[0021] In the wet wipes package, in a plan view in the removal direction of the removal portion, at least a part of the outer edge of the outer cover member opening includes an inner portion of the outer cover member that is disposed inward from the outer edge of the base material layer opening, and thus the inner portion of the outer cover member prevents the wipe from coming into direct contact with the base material layer opening, thereby preventing the medicinal solution from migrating into the cellulose-based base material layer and making it difficult to remove the wipe.

[0022] [Aspect 5] A packaging body for wet wipes according to aspect 4, wherein at least a portion of the outer cover member is fixed to the impermeable layer inside the outer edge of the base layer opening.

[0023] In the wet wipes package, at least a part of the inner part of the outer cover member is fixed to the inner part of the impermeable layer to form a fixing part, so that the drug solution is less likely to migrate to the cellulose-based base material at the cross section of the base material layer opening in the part where the fixing part exists both before and after the start of use of the package, and the drug solution can be retained.

[0024] In this disclosure, the terms "fixing portion," "fix" and "fixed" mean that two or more components 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.

[0025] [Aspect 6] A packaging body for wet wipes according to any one of aspects 3 to 5, wherein an adhesive layer is disposed on the inner surface of the outer cover member, and at least a portion of the outer edge of the opening of the outer cover member is disposed outward from the outer edge of the opening of the impermeable layer in the plan view.

[0026] In the wet wipes package, an adhesive layer is disposed on the inner surface of the outer cover member, and at least a portion of the outer edge of the outer cover member opening is disposed outward from the outer edge of the impermeable layer opening. Therefore, in the package, in the portion where at least a portion of the outer edge of the outer cover member opening is disposed outward from the outer edge of the impermeable layer opening, the adhesive layer disposed on the outer cover member is unlikely to adhere to the wipe when the wipe is removed.

[0027] [Aspect 7] The wet wipes package according to any one of aspects 3 to 6, wherein the outer surface of the outer cover member constitutes a release surface. In the above-mentioned wet wipes package, the outer surface of the outer cover member constitutes the release surface, so that the flap label has excellent repetitive opening and closing properties.

[0028] [Aspect 8] A packaging body for wet wipes according to any one of aspects 1 to 7, wherein the flap label comprises a base member arranged on the packaging body side and a lid member connected to the base member so as to be repeatedly opened and closed, and the base member and the lid member are integrally formed.

[0029] 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.

[0030] [Aspect 9] A packaging material for wet wipes according to any one of aspects 1 to 8, wherein the cellulosic base material layer comprises rayon.

[0031] 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.

[0032] [Aspect 10] A method for producing a packaging body for a packaging of wet wipes according to embodiment 1, comprising the steps of: a preparation step of preparing a laminate of the cellulosic base material layer having the base material layer opening and an impermeable layer not having the impermeable layer opening; The above method.

[0033] The above manufacturing method includes a predetermined preparation step, and therefore can easily form a package for the wet wipes according to the present disclosure.

[0034] [Aspect 11] The method according to aspect 10, comprising the step of forming an impermeable layer opening in an area of ​​the laminate that overlaps with the base layer opening. Since the above method further includes a predetermined impermeable layer opening forming step, the impermeable layer opening can be accurately formed inside the base material layer opening in plan view in the removal direction.

[0035] 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 6 are diagrams for explaining a wet wipes package 1 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 7 in the IV-IV end view of FIG. 3. FIG. 5 is a partially enlarged end view of the vicinity of the removal portion 7 in the IV-IV end view of FIG. 3, showing a state in which the flap label 9 is opened after the start of use of the package 1. FIG. 6 is a partially enlarged end view of the vicinity of the removal portion 7 in the IV-IV end view of FIG. 3, showing the wipes 3 being removed. It should be noted that the drawings are intended to aid in understanding the present disclosure, and the ratios of the components constituting the packaging body 1 (the ratios in the first direction D1, second direction D2, and third direction D3 described below) do not accurately reflect the actual ones, and in particular in the end view, the third direction D3 is shown relatively enlarged compared to the first direction D1 and the second direction D2.

[0036] 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.

[0037] The package 1 according to the first embodiment includes a package body 5 in which a plurality of wipes 3 and a medicinal solution (not shown) are stored, a removal section 7, and a flap label 9 that covers the removal section 7 in a repeatedly openable and closable manner. Each of the wipes 3 is folded and stacked in the third direction D3, but as this is not a characteristic feature of the present disclosure, a detailed description thereof will be omitted.

[0038] 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.

[0039] The packaging body 5 has an inner surface 11 and an outer surface 13, and is provided with a cellulosic base material layer 15 disposed on the outer surface 13 side, and an impermeable layer 19 disposed on the inner surface 11 side. The cellulosic base material layer 15 forms the outer surface 13 of the packaging body 5, and the impermeable layer 19 forms the inner surface 11 of the packaging body 5.

[0040] The cellulose-based base material layer 15 has a base material layer opening 17 in the removal portion 7. The impermeable layer 19 has an impermeable layer opening 21 in the removal portion 7. Specifically, the impermeable layer opening 21 is an impermeable layer opening forming portion 21b that forms the impermeable layer opening 21a when the flap label 9 is opened for the first time at the start of use of the package 1. The outer edge of the impermeable layer opening forming portion 21b is defined by a weakened line 27.

[0041] The packaging body 1 further includes a water-impermeable outer cover member 23 between the flap label 9 and the packaging body 5 at the removal section 7. The outer cover member 23 includes an outer cover member opening 25. Specifically, the outer cover member opening 25 is an outer cover member opening forming portion 25b that forms an outer cover member opening 25a when the flap label 9 is first opened at the start of use of the packaging body 1. The outer edge of the outer cover member opening forming portion 25b is defined by a weakened line 27.

[0042] In plan view in the third direction D3, which corresponds to the removal direction of the removal portion 7, the area of ​​the impermeable layer opening 21 of the impermeable layer 19 is smaller than the area of ​​the base material layer opening 17 of the cellulose-based base material layer 15. In addition, in plan view in the third direction D3, the outer edge of the impermeable layer opening 21 of the impermeable layer 19 is disposed inward from the outer edge of the base material layer opening 17 of the cellulose-based base material layer 15. In plan view in the third direction D3, the outer edge of the outer cover member opening 25 of the outer cover member 23 coincides with the outer edge of the impermeable layer opening 21 of the impermeable layer 19, and is disposed inward from the outer edge of the base material layer opening 17 of the cellulose-based base material layer 15.

[0043] The flap label 9 has a flap label inner surface 31 on the inner surface 11 side and a flap label outer surface 33 on the outer surface 13 side in the third direction D3, and has an adhesive layer (not shown) on the flap label inner surface 31. In the third direction D3, the outer cover member 23 has an outer cover member inner surface 41 on the inner surface 11 side and an outer cover member outer surface 43 on the outer surface 13 side. The outer cover member outer surface 43 is a release surface coated with a release agent, thereby bonding the flap label 9 to the outer cover member 23 so as to be repeatedly openable and closable. The outer cover member 23 has an adhesive layer (not shown) on the outer cover member inner surface 41.

[0044] The impermeable layer 19 has an impermeable layer inner surface 35 arranged on the inner surface 11 side and an impermeable layer outer surface 37 arranged on the outer surface 13 side in the third direction D3. The impermeable layer 19 has an adhesive layer (not shown) coated with an adhesive on the impermeable layer outer surface 37, and the impermeable layer 19 is fixed to the cellulose-based base material layer 15 by the adhesive layer. The impermeable layer inner surface 35 constitutes the inner surface 11 of the packaging body 5.

[0045] Before the package 1 is used, the impermeable layer 19 has a wall portion 19b that stands toward the flap label 9 (outer cover member 23) and a top portion 19c that contacts the outer cover member 23. The impermeable layer 19 is fixed to the outer cover member 23 at the top portion 19c.

[0046] The weakened line 27 that defines the outer edge of the impermeable layer opening 21 and the weakened line 27 that defines the outer edge of the outer cover member opening 25 are integrally formed. Specifically, the package 1 is provided with the weakened line 27 at the outer edge of the top 19c of the impermeable layer 19 for cutting the impermeable layer opening forming portion 21b and the outer cover member opening forming portion 25b when the flap label 9 is first opened to form the impermeable layer opening 21a and the outer cover member opening 25a, respectively.

[0047] The weakened line 27 is formed by cutting the impermeable layer 19 and the outer cover member 23 from the impermeable layer 19 side so as to go around the outer edge of the top 19c and to penetrate the impermeable layer 19 but not the outer cover member 23. As a result, when the flap label 9 is opened for the first time, the outer edge of the top 19c (the outer edge of the impermeable layer opening forming portion 21b and the outer edge of the outer cover member opening forming portion 25b) is cut to form the impermeable layer opening 21a and the outer cover member opening 25a, and the wipes can be removed.

[0048] In the packaging body 1, the impermeable layer opening 21 and the outer cover member opening 25 are, respectively, the impermeable layer opening forming portion 21b and the outer cover member opening forming portion 25b, and the weakened line 27 that defines them is formed so as not to penetrate the outer cover member 23. Therefore, before use of the packaging body 1 begins, the packaging body 1 has excellent medicinal solution retention properties.

[0049] After the flap label 9 is first opened, a portion of the cellulose-based base material layer 15 that is inward from the outer edge of the base material layer opening 17 and outward from the weakened line 27 remains in plan view in the third direction D3, and this remaining portion is referred to as the impermeable layer inner portion 19a. The impermeable layer inner portion 19a has a substantially quadrangular ring structure (not shown) in plan view in the third direction D3. The substantially quadrangular ring structure may hereinafter be referred to as a "corner ring structure."

[0050] Similarly, after the flap label 9 is initially opened, a portion of the outer cover member 23 remains inward from the outer edge of the base material layer opening 17 of the cellulose-based base material layer 15 and outward from the weakened line 27 in plan view in the third direction D3, and this remaining portion is referred to as the outer cover member inner portion 23a. The outer cover member inner portion 23a has a square ring structure (not shown) in plan view in the third direction D3.

[0051] The impermeable layer inner part 19a and the outer cover member inner part 23a are fixed by an adhesive layer of the impermeable layer 19 and an adhesive layer of the outer cover member 23 to form a fixing part 29. The fixing part 29 has a square ring structure in plan view in the third direction D3, similar to the impermeable layer inner part 19a and the outer cover member inner part 23a. As a result, the package 1 has a simpler structure than the sheet package disclosed in Patent Document 1, and can prevent the medicinal solution from reaching the cellulose-based base material layer 15 both before and after use of the package 1 begins.

[0052] The package body 5 includes the cellulose-based base material layer 15, 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 base material layer opening 17, the medicinal solution impregnated in the wipe 3 may transfer to the cellulose-based base material layer 15, and the wipe 3 may get caught in the base material layer opening 17, making it difficult to take out.

[0053] In the packaging body 1, as shown in FIG. 6, the fixing portion 29 composed of the impermeable layer inner portion 19a and the outer cover member inner portion 23a prevents the wipes 3 from coming into direct contact with the base material layer opening 17, thereby making it difficult to remove the wipes 3.

[0054] [Second 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 "second embodiment"). Fig. 7 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 descriptions of the same parts will be omitted as appropriate.

[0055] The packaging body 1 according to the second embodiment comprises, in the third direction D3, a flap label 9, an outer cover member 23, and a packaging body 5 (a cellulosic base material layer 15 and a water-impermeable layer 19) in that order. The flap label 9 has a flap label inner surface 31 on the inner surface 11 side and a flap label outer surface 33 on the outer surface 13 side in the third direction D3, and has an adhesive layer (not shown) on the flap label inner surface 31.

[0056] In the third direction D3, the outer cover member 23 has an outer cover member inner surface 41 on the inner surface 11 side and an outer cover member outer surface 43 on the outer surface 13 side, and has an adhesive layer (not shown) on the outer cover member inner surface 41, and the outer cover member outer surface 43 is a release surface to which a release agent is applied. In the third direction D3, the impermeable layer 19 has an impermeable layer inner surface 35 on the inner surface 11 side and an impermeable layer outer surface 37 on the outer surface 13 side, and has an adhesive layer (not shown) on the impermeable layer outer surface 37.

[0057] The cellulose-based base material layer 15 has a base material layer opening 17 in the removal section 7, and the impermeable layer 19 has an impermeable layer opening 21 in the removal section 7. Specifically, the impermeable layer opening 21 is an impermeable layer opening 21a having a through hole for removing the wipes before the start of use of the package 1 (before the flap label 9 is opened for the first time). The outer cover member 23 has an outer cover member opening 25 at the removal portion 7. Specifically, the outer cover member opening 25 is an outer cover member opening 25a having a through hole for removing the wipes before the start of use of the package 1 (before the flap label 9 is opened for the first time).

[0058] In plan view in the third direction D3, the area of ​​the impermeable layer opening 21a of the impermeable layer 19 and the area of ​​the outer cover member opening 25a of the outer cover member 23 are smaller than the area of ​​the base material layer opening 17 of the cellulose-based base material layer 15. In addition, in plan view in the third direction D3, the outer edge of the impermeable layer opening 21a of the impermeable layer 19 and the outer edge of the outer cover member opening 25a of the outer cover member 23 are disposed inward from the outer edge of the base material layer opening 17 of the cellulose-based base material layer 15. In addition, the outer edge of the impermeable layer opening 21a of the impermeable layer 19 and the outer edge of the outer cover member opening a25 of the outer cover member 23 coincide with each other in plan view in the third direction D3.

[0059] The impermeable layer 19 has an impermeable layer inner portion 19a arranged inward from the outer edge of the base layer opening 17, and the impermeable layer inner portion 19a has a square ring structure. The outer cover member 23 has an outer cover member inner portion 23a arranged inward from the outer edge of the base layer opening 17, and the outer cover member inner portion 23a has a square ring structure.

[0060] In the removal section 7, the outer cover member inner part 23a of the outer cover member 23 and the impermeable layer inner part 19a of the impermeable layer 19 are fixed to each other via their adhesive layers to form a fixing part 29. The fixing part 29 has a square ring structure in a plan view in the third direction D3. This makes it difficult for the medicinal solution to transfer to the cellulose-based base material layer 15 in the cross section of the base material layer opening 17 both before and after the start of use of the package 1.

[0061] [Third 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 "third 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 descriptions of the same parts will be omitted as appropriate.

[0062] The packaging body 1 according to the third embodiment comprises, in a third direction D3, a flap label 9 and a packaging body 5 (a cellulosic base material layer 15 and a water-impermeable layer 19) in that order. The flap label 9 includes a base member 61 and a lid member 63 joined to the base member 61 so as to be repeatedly openable and closable.

[0063] The base member 61 and the lid member 63 constituting the flap label 9 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 61, and the base member 61 is fixed to the cellulose-based base material layer 15 of the packaging body 5. The outer surface (not shown) of the base member 61 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 63, and is bonded to the outer surface (release surface) of the base member 61 so as to be repeatedly openable and closable. The second adhesive layer (second adhesive) has lower adhesiveness than the first adhesive layer (first adhesive), and the outer surface of the base member 61 is provided with a release surface, so that the lid member 63 can be repeatedly opened and closed, and the base member 61 can remain fixed to the cellulose-based base material layer 15 when the lid member 63 is opened and closed.

[0064] The cellulose-based base material layer 15 has a base material layer opening 17 at the removal portion 7. The impermeable layer 19 has an impermeable layer opening 21 at the removal portion 7. Specifically, the impermeable layer opening 21 is an impermeable layer opening forming portion 21b that forms an impermeable layer opening (not shown) when the flap label 9 is opened at the start of use of the package 1. The outer edge of the impermeable layer opening forming portion 21b is defined by a weakened line 27.

[0065] The base member 61 has a base member opening 65 at the removal portion 7. Specifically, the base member opening 65 is a base member opening forming portion 65b that forms a base member opening (not shown) when the flap label 9 is opened at the start of use of the package 1. The outer edge of the base member opening forming portion 65b is defined by the weakened line 27.

[0066] In plan view in the third direction D3, which corresponds to the removal direction of the removal portion 7, the area of ​​the impermeable layer opening 21 of the impermeable layer 19 and the area of ​​the base member opening 65 are smaller than the area of ​​the base material layer opening 17 of the cellulosic base material layer 15. In addition, in plan view in the third direction D3, the outer edge of the impermeable layer opening 21 of the impermeable layer 19 and the outer edge of the base member opening 65 of the base member 61 are disposed inward from the outer edge of the base material layer opening 17 of the cellulosic base material layer 15. In addition, the outer edge of the impermeable layer opening 21a of the impermeable layer 19 and the outer edge of the base member opening 65 of the base member 61 coincide with each other in plan view in the third direction D3.

[0067] The impermeable layer 19 has an impermeable layer inner surface 35 arranged on the inner surface 11 side and an impermeable layer outer surface 37 arranged on the outer surface 13 side in the third direction D3. The impermeable layer 19 has an adhesive layer (not shown) coated with an adhesive on the impermeable layer outer surface 37, and the impermeable layer 19 is fixed to the cellulose-based base material layer 15 by the adhesive layer. The impermeable layer inner surface 35 constitutes the inner surface 11 of the packaging body 5.

[0068] Before the package 1 is used, the impermeable layer 19 has a wall portion 19b that stands toward the flap label 9 (outer cover member 23) and a top portion 19c that contacts the base member 61 of the flap label 9. The impermeable layer 19 is fixed to the base member 61 at the top portion 19c.

[0069] The weakened line 27 that defines the outer edge of the impermeable layer opening 21 is formed integrally with the impermeable layer 19 and the base member 61. Specifically, the package 1 is provided with the weakened line 27 at the outer edge of the top 19c of the impermeable layer 19 for cutting the impermeable layer opening forming portion 21b and the base member opening forming portion 65b to form the impermeable layer opening 21a and the base member opening (not shown) when the flap label 9 (specifically, the lid member 63) is first opened.

[0070] The weakened line 27 is formed by cutting the impermeable layer 19 and the base member 61 from the impermeable layer 19 side so as to go around the outer edge of the top 19c and penetrate the impermeable layer 19 but not penetrate the base member 61. As a result, when the flap label 9 is opened for the first time, the outer edge of the top 19c (the outer edge of the impermeable layer opening forming portion 21b and the outer edge of the base member opening forming portion 65b) is cut to form the impermeable layer opening 21a and the base member opening, and the wipes can be removed.

[0071] The packaging body 1 according to the third embodiment corresponds to the packaging body 1 according to the first embodiment in which the outer cover member 23 is replaced with the base member 61 of the flap label 9. Therefore, for further effects and advantages of the packaging body 1 according to the third embodiment, please refer to the packaging body 1 according to the first embodiment, and a description thereof will be omitted.

[0072] [Fourth embodiment] Fig. 9 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. 9 is a diagram corresponding to Fig. 4 in the first embodiment. Note that in the package 1 according to the fourth embodiment, the following description will focus on the parts that are different from the package 1 according to the first embodiment, and descriptions of the same parts will be omitted as appropriate.

[0073] The packaging body 1 according to the fourth embodiment comprises a flap label 9 and a packaging body 5 (a cellulosic base material layer 15 and a water-impermeable layer 19) in that order in the third direction D3. The flap label 9 has a flap label inner surface 31 on the inner surface 11 side and a flap label outer surface 33 on the outer surface 13 side in the third direction D3. The flap label 9 has an adhesive layer (not shown) on the flap label inner surface 31, and the flap label 9 is fixed to the cellulose-based base material layer 15 by the adhesive layer.

[0074] The impermeable layer 19 has an impermeable layer inner surface 35 arranged on the inner surface 11 side and an impermeable layer outer surface 37 arranged on the outer surface 13 side in the third direction D3. The impermeable layer 19 has an adhesive layer (not shown) coated with an adhesive on the impermeable layer outer surface 37, and the impermeable layer 19 is fixed to the cellulose-based base material layer 15 by the adhesive layer. The impermeable layer inner surface 35 constitutes the inner surface 11 of the packaging body 5.

[0075] The cellulosic base material layer 15 has a base material layer opening 17 at the removal section 7. The impermeable layer 19 has an impermeable layer opening 21 at the removal section 7. The impermeable layer opening 21 is specifically an impermeable layer opening 21a that already has a through hole for removing the wipes before the start of use of the package 1.

[0076] In plan view in the third direction D3, which corresponds to the removal direction of the removal portion 7, the area of ​​the impermeable layer opening 21 of the impermeable layer 19 is smaller than the area of ​​the base material layer opening 17 of the cellulosic base material layer 15. In addition, in plan view in the third direction D3, the outer edge of the impermeable layer opening 21 of the impermeable layer 19 is positioned inward from the outer edge of the base material layer opening 17 of the cellulosic base material layer 15. The impermeable layer 19 has an impermeable layer inner portion 19a that is disposed inward from the outer edge of the base layer opening 17, and the impermeable layer inner portion 19a has a rectangular ring structure.

[0077] In the packaging body 1 according to the fourth embodiment, the impermeable layer opening 21 is an impermeable layer opening 21a that already has a through hole for removing wipes before use of the packaging body 1 begins, and therefore has a simpler structure than the sheet packaging body disclosed in Patent Document 1 and can prevent the medicinal solution from reaching the cellulose-based base material layer 15 to a certain extent before use of the packaging body 1 begins. Furthermore, in the package 1, the impermeable layer inner portion 19a prevents the wipes 3 from directly contacting the base layer openings 17, making it possible to reduce the difficulty in removing the wipes 3.

[0078] In the packaging body 1, an adhesive layer is provided on the flap label inner surface 31 of the flap label 9, and an adhesive layer is provided on the impermeable layer outer surface 37 of the impermeable layer 19. Therefore, before and after the start of use of the packaging body 1, at least a part of the impermeable layer inner portion 19a of the impermeable layer 19 can adhere to the flap label 9 and the cellulose-based base material layer 15, so that the medicinal solution is less likely to transfer to the cellulose-based base material layer 15.

[0079] 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 perpendicular to each other can be planar directions of the wipes. For example, the first and second directions can be the longitudinal and lateral directions of the package, respectively.

[0080] A wet wipes package according to the present disclosure includes a package body housing a plurality of wipes and a medical solution. 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.

[0081] 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).

[0082] 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.

[0083] 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).

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] The wipes can be stacked 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.

[0096] 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.

[0097] In the package according to the present disclosure, the package body has an inner surface and an outer surface, the inner surface being 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.

[0098] 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.

[0099] 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 base material layer opening of the cellulose-based base material layer. However, in the packaging body of the present disclosure, the inner part of the impermeable layer prevents the wipes from coming into direct contact with the base material layer opening, thereby reducing the difficulty of removing the wipes. Furthermore, when the cellulosic base material layer contains pulp fibers, for example when the packaging body contains 50% by mass or more of pulp fibers, the packaging body can be disposed of as paper waste.

[0100] When the above-mentioned cellulose-based base material layer contains regenerated cellulose fibers (e.g., rayon), refined cellulose fibers, semi-synthetic fibers, etc., there are effects such as reducing the generation of noise caused by deformation of the packaging body when the wet wipes package is used, and making the wet wipes package more luxurious.

[0101] The impermeable layer can be directly or indirectly fixed to the cellulose-based substrate layer from the viewpoint of protecting the cellulose-based substrate layer, and is preferably directly fixed to the cellulose-based substrate layer. In addition, the impermeable layer preferably covers at least 50%, more preferably at least 60%, even more preferably at least 70%, even more preferably at least 80%, and even more preferably at least 90% of the inner surface of the package body from the viewpoint of protecting the cellulose-based substrate layer. In addition, the impermeable layer is preferably arranged as an integral member. This is because, when the impermeable layer is composed of a plurality of separate members, the drug solution may penetrate into the cellulose-based substrate layer through gaps between the separate members.

[0102] The impermeable layer is not particularly limited as long as it does not allow water to pass through, and may include, for example, a barrier layer, a sealant layer, a combination thereof, or the like. Examples of the material for the barrier layer include a resin film such as polyethylene terephthalate or nylon, on which alumina, silica, etc. are vapor-deposited. Examples of the material for the sealant layer include thin films having heat sealability such as low-density polyethylene (LDPE) or non-axially oriented polypropylene (CPP).

[0103] Examples of the material for the impermeable layer include films, such as synthetic resin films, for example, polyolefins (eg, polyethylene, polypropylene, etc.), polyethylene terephthalate, polyester, polyamide, polyvinyl chloride, etc.

[0104] 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-based base material layer is exposed in the cross section of the base material layer opening of the cellulose-based base material layer, and it is preferable that when the flap label is in an unopened state, 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-based base material layer is exposed in the cross section of the base material layer opening. Incidentally, the above-mentioned "exposed" means that the cross section of the cellulose-based substrate layer is not directly or indirectly covered with a waterproof material such as a film.

[0105] The package includes a dispenser section for dispensing the wipes and a flap label directly or indirectly covering the dispenser section so that the dispenser section can be repeatedly opened and closed. The removal portion refers to the area overlapping with the flap label in the third direction, and the area between the flap label and the packaging body.

[0106] 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.

[0107] In the package according to the present disclosure, the cellulose-based base material layer has a base material layer opening in the removal section, and the impermeable layer has an impermeable layer opening or an impermeable layer opening forming section capable of forming the impermeable layer opening in the removal section. The impermeable layer opening means an impermeable layer opening that already has a through-hole for removing wipes when the package is in a state before use (when the flap label is unopened). The impermeable layer opening forming section means an impermeable layer opening that does not have a through-hole for removing wipes when the package is in a state before use, but has a through-hole for removing wipes after use of the package is started (after the flap label is opened).

[0108] The impermeable layer opening forming portion is not particularly limited as long as it is capable of forming an impermeable layer opening when the package starts to be used (e.g., when the flap label is first opened), and may be defined by a weakened line, for example. The weakened line may be, for example, a cut portion that is continuously or intermittently arranged in a direction perpendicular to the removal direction (e.g., the first direction and the second direction) along the impermeable layer opening forming portion and that may or may not penetrate in the removal direction (e.g., the third direction).

[0109] In a plan view in the removal direction of the removal section, the entire outer edge of the impermeable layer opening is disposed inside the outer edge of the base layer opening. In addition, in a plan view in the removal direction of the removal section, the area of ​​the impermeable layer opening is smaller than the area of ​​the base layer opening. In addition, in a plan view in the removal direction of the removal section, a portion of the impermeable layer disposed inside the outer edge of the base layer opening may be referred to as an impermeable layer inner portion. As a result, the impermeable layer inner portion of the impermeable layer disposed inside the outer edge of the base layer opening suppresses the wipe from directly contacting the base layer opening, and the transfer of the chemical solution to the cellulose-based base layer and the difficulty in removing the wipe can be suppressed.

[0110] The package according to the present disclosure may further include a water-impermeable outer cover member between the flap label and the package body at the removal section. The outer cover member may include an outer cover member opening or an outer cover member opening forming section capable of forming the outer cover member opening. 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.

[0111] Examples of materials for the impermeable outer cover member include films, for example, synthetic resin films, for example, polyolefins (eg, polyethylene, polypropylene, etc.), polyethylene terephthalate, polyester, polyamide, polyvinyl chloride, etc. 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.

[0112] When the package according to the present disclosure includes the outer cover member, the outer cover member opening may have the same area as the base material layer opening, a larger area than the base material layer opening, or a smaller area than the base material layer opening in a plan view in the removal direction of the removal section. It is preferable that the outer cover member opening has the same area as the base material layer opening or a smaller area than the base material layer opening. This makes it easier for the outer cover member to protect the cellulose-based base material layer.

[0113] When the outer cover member opening has an area smaller than the base material layer opening, it is preferable that at least a part of the outer edge of the outer cover member opening is located inside the outer edge of the base material layer opening in a plan view in the removal direction of the removal part, and it is preferable that the entire outer edge of the outer cover member opening is located inside the outer edge of the base material layer opening. This makes it difficult for the wipes to directly touch the cellulose-based base material layer when removing them from the package. Note that the part of the outer cover member that is located inside the outer edge of the base material layer opening in a plan view in the removal direction of the removal part may be referred to as the inner part of the outer cover member.

[0114] In this case, it is preferable that at least a part of the inner part of the outer cover member is fixed to at least a part of the inner part of the impermeable layer along the outer edge of the outer cover member opening (along the outer edge of the impermeable layer opening), and it is preferable that at least a part of the inner part of the outer cover member is fixed to at least a part of the inner part of the impermeable layer around the outer edge of the outer cover member opening (around the outer edge of the impermeable layer opening). This makes it difficult for the drug solution to migrate to the cellulose-based substrate in the cross section of the substrate layer opening in the package.

[0115] From the viewpoint that at least a portion of the inner portion of the outer cover member is fixed to at least a portion of the inner portion of the impermeable layer, in a planar view in the removal direction of the removal portion, the area of ​​the outer cover member opening may be the same as the impermeable layer opening of the impermeable layer, may be larger than the impermeable layer opening of the impermeable layer, or may be smaller than the impermeable layer opening of the impermeable layer, and it is preferable that, in a planar view in the removal direction of the removal portion, the outer cover member opening has the same area as the impermeable layer opening of the impermeable layer and has an area larger than the impermeable layer opening of the impermeable layer.

[0116] When the outer cover member opening of the outer cover member has the same area as the impermeable layer opening of the impermeable layer, it is preferable that the outer edge of the outer cover member opening of the outer cover member coincides with the outer edge of the impermeable layer opening of the impermeable layer in a plan view in the removal direction of the removal section, thereby making it possible to easily form the outer edge of the outer cover member opening of the outer cover member and the outer edge of the impermeable layer opening of the impermeable layer in the same process.

[0117] When the outer cover member opening of the outer cover member has an area larger than the impermeable layer opening of the impermeable layer, it is preferable that the outer edge of the outer cover member opening of the outer cover member is disposed outside the outer edge of the impermeable layer opening of the impermeable layer in a plan view in the removal direction of the removal part, so that when an adhesive layer or the like made of an adhesive is disposed on the inner surface of the outer cover member of the outer cover member, the adhesive layer is less likely to come into contact with and transfer to the wipes.

[0118] When the outer edge of the outer cover member opening is the same as the outer edge of the base material layer opening, it is preferable that the outer edge of the outer cover member opening and the outer edge of the base material layer opening coincide with each other in a plan view in the removal direction of the removal portion, whereby the base material layer opening and the outer cover member opening can be easily formed in the same process.

[0119] The outer cover member opening means an outer cover member opening that already has a through-hole for removing wipes when the package is in a state before use (when the flap label is unopened), and the outer cover member opening forming portion means an outer cover member opening that does not have a through-hole for removing wipes when the package is in a state before use, but has a through-hole for removing wipes after use of the package is started (after the flap label is opened).

[0120] The outer cover member opening forming portion is not particularly limited as long as it is capable of forming an outer cover member opening when the package starts to be used (e.g., when the flap label is first opened), and may be defined by a weakened line, for example. The weakened line may be, for example, a cut portion that is continuously or intermittently arranged in a direction perpendicular to the removal direction (e.g., the first direction and the second direction) along the outer cover member opening forming portion and that may or may not penetrate in the removal direction (e.g., the third direction).

[0121] When the package according to the present disclosure includes an outer cover member and the outer edge of the impermeable layer opening forming portion coincides with the outer cover member opening forming portion in a plan view in the removal direction, the weakened line that defines the impermeable layer opening forming portion and the weakened line that defines the outer cover member opening forming portion may be integrally formed weakened lines. This allows the impermeable layer opening forming portion and the outer cover member opening forming portion to be easily formed. Furthermore, when the package according to the present disclosure is first used, for example, when the flap label is first opened, the impermeable layer opening and the outer cover member opening can be appropriately formed from the impermeable layer opening forming portion and the outer cover member opening forming portion, respectively.

[0122] The integrally formed weakened lines can be, for example, arranged continuously or intermittently in a direction perpendicular to the removal direction (e.g., the first direction and the second direction) along the impermeable layer opening forming portion and the outer cover member opening forming portion, and can be cut portions that penetrate the impermeable layer but do not penetrate the outer cover member in the removal direction (e.g., the third direction). Furthermore, the integrally formed weakened lines may be, for example, intermittently arranged in a direction perpendicular to the removal direction (e.g., the first direction and the second direction) along the impermeable layer opening forming portion and the outer cover member opening forming portion, and may be cut portions penetrating the impermeable layer and the outer cover member in the removal direction (e.g., the third direction).

[0123] The weakened line and the integrally formed weakened line are preferably configured such that the medicinal liquid held inside the packaging body does not reach the flap label before the packaging body is used. This is from the viewpoint of holding the medicinal liquid. From this viewpoint, for example, when the packaging body according to the present disclosure does not include an outer cover member, the weakened line formed in the impermeable layer opening forming portion can be a cut portion that does not penetrate the impermeable layer, and when the packaging body according to the present disclosure includes an outer cover member, the weakened line formed in the outer cover member opening forming portion can be a cut portion that does not penetrate the outer cover member.

[0124] In the package according to the present disclosure, the flap label can include a base member disposed on the package body side and a lid member joined to the base member so as to be repeatedly openable and closable, which 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.

[0125] 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. 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 described below.

[0126] The base member may have, at the removal section, a base member opening for removing the wipes, or a base member opening forming section capable of forming the base member. This allows the wipes to be easily removed from the package. The base member opening forming section is not particularly limited as long as it is capable of forming a base member opening when the package starts to be used (for example, when the flap label is first opened), but may be defined, for example, by a weakened line. The weakened line may be, for example, a cut section that is continuously or intermittently arranged in a direction perpendicular to the removal direction (for example, the first direction and the second direction) along the base member opening forming section and that penetrates or does not penetrate in the removal direction (for example, the third direction).

[0127] In the package according to the present disclosure, when the flap label includes a lid member and a base member, and when the impermeable layer includes an impermeable layer opening-forming portion and the base member includes a base member opening-forming portion, the weakened line that defines the impermeable layer opening-forming portion and the weakened line that forms the base member opening-forming portion may be integrally formed weakened lines. Thereby, when starting to use the package according to the present disclosure, for example, when opening the flap label (specifically, the lid member) for the first time, an impermeable layer opening can be formed from the impermeable layer opening-forming portion and a base member opening can be easily formed from the base member opening-forming portion.

[0128] The integrally formed weakened lines can be, for example, arranged continuously or intermittently in a direction perpendicular to the removal direction (e.g., the first and second directions) along the impermeable layer opening formation portion and the base member opening formation portion, and can be cut portions that penetrate the impermeable layer but do not penetrate the base member in the removal direction (e.g., the third direction). Furthermore, the integrally formed weakened lines may be, for example, intermittently arranged in a direction perpendicular to the removal direction (e.g., the first direction and the second direction) along the impermeable layer opening formation portion and the base member opening formation portion, and may be cut portions penetrating the impermeable layer and the base member in the removal direction (e.g., the third direction).

[0129] The above-mentioned integrally formed weakened line is preferably configured so that the medicinal liquid held inside the package body does not reach the lid member of the flap label before the package is used, from the viewpoint of holding the medicinal liquid. From this viewpoint, for example, the weakened line formed in the base member may be a cut portion that does not penetrate the base member. The base member opening of the base member is similar to the outer cover member opening of the outer cover member, so please refer to the section relating to the outer cover member opening and other explanations will be omitted.

[0130] The flap label may have an adhesive layer made of a pressure-sensitive adhesive on its inner surface (the surface on the impermeable layer side) which is the surface closer to the inside of the packaging body, and the flap label may be directly or indirectly attached 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 the start of use of the wet wipes, the part of the impermeable layer located inside the base layer opening of the packaging body, i.e., part of the part inside the impermeable layer, can adhere to the flap label, making it difficult for the drug solution to transfer to the cellulose-based base material.

[0131] The impermeable layer may be provided on the outer surface of the impermeable layer, which is the surface on the flap label side, with an adhesive, i.e., an adhesive layer made of a pressure-sensitive adhesive, and the impermeable layer may be fixed directly or indirectly to the cellulose-based substrate layer by the adhesive layer. As a result, when the flap label is closed after the start of use of the wet wipes, a part of the inner part of the impermeable layer can adhere to the cellulose-based substrate, the flap label, etc., at the cross section of the substrate layer opening, so that the chemical solution is less likely to transfer to the cellulose-based substrate.

[0132] The impermeable layer may or may not have an adhesive layer on its inner surface. For example, when the impermeable layer constitutes the inner surface of the package body, the impermeable layer generally does not have an adhesive layer on its inner surface so that the components of the adhesive layer do not migrate to the wipes.

[0133] The impermeable layer openings of the impermeable layer (impermeable layer openings and impermeable layer opening forming portions), the base material layer openings of the cellulose-based base material layer, the outer cover member openings of the optional outer cover member (outer cover member openings and outer cover member opening forming portions), and the base member openings of the optional base member (hereinafter, these openings may be collectively referred to simply as "openings") may have any shape. The openings may be, for example, a perfect circle, an ellipse (for example, an ellipse having a major axis in a first direction), a rounded square, a rounded rectangle (for example, a rounded rectangle having a long side in a first direction), etc.

[0134] For example, in the packaging body of 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), it is easier to prevent the wet wipes from coming into direct contact with the opening (particularly the base material layer opening) when the wipes are removed from the removal opening.

[0135] The packages according to the present disclosure can be manufactured by any method. For example, a method for producing a package according to the present disclosure (hereinafter, sometimes referred to as the "production method according to the present disclosure") may include, for example, the following steps. - a preparation step of preparing a laminate of the cellulosic base material layer having the base material layer opening and the impermeable layer having no impermeable layer opening (hereinafter, may be referred to as the "preparation step"); - an impermeable layer opening forming step of forming the impermeable layer opening within an area overlapping with the base layer opening of the laminate (hereinafter, may be referred to as an "impermeable layer opening forming step");

[0136] In the preparation step, a laminate of a cellulosic base material layer having a base material layer opening and an impermeable layer having no impermeable layer opening is prepared. In the preparation step, for example, the cellulosic substrate layer can be fixed to the impermeable layer by an adhesive layer disposed on the outer surface of the impermeable layer. The laminate may further include an outer cover member, a flap label, and the like.

[0137] In the impermeable layer opening forming step, an opening in the impermeable layer is formed in an area of ​​the laminate that overlaps with the base layer opening. The impermeable layer openings can be formed by a method known in the art, for example, by passing the laminate through a cutter section consisting of a cutter roll having the same blade as the impermeable layer openings, and an anvil roll.

[0138] When the laminate further includes an outer cover member, in the impermeable layer opening forming step, the impermeable layer opening of the impermeable layer and the outer cover member opening of the outer cover member may be formed simultaneously, for example, the weakened line defining the impermeable layer opening forming portion and the weakened line defining the outer cover member opening forming portion may be formed as an integrally formed weakened line.

[0139] The manufacturing method according to the present disclosure may further include a laminate formation step, prior to the preparation step, of laminating the cellulosic substrate layer having the substrate layer opening and an impermeable layer not having the impermeable layer opening to form a laminate. In the laminate formation step, in addition to the cellulosic base material layer having the base material layer opening and the impermeable layer not having the impermeable layer opening, a flap label, an optional outer cover member, etc. can be further laminated.

[0140] The manufacturing method according to the present disclosure can be used in a batch mode to form one package at a time, or in a continuous mode to form multiple packages. The manufacturing method according to the present disclosure can include further steps known in the art to form a package of wet wipes. [Explanation of symbols]
