Technical Field

[0001] This invention relates to a cover material for sheet packaging and a sheet packaging with a cover material. Background Technology

[0002] Previously, it was known that there were "bottle-type" sanitary tissue storage containers (for example, see Patent Document 1) used to store rolled wet sheets by transferring them from a sheet packaging body to a storage container made of plastic such as polyethylene, and to remove the sheets from the storage container.

[0003] Patent Document 1: Japanese Patent No. 6564480

[0004] The tissue paper storage container for hygiene products in the aforementioned patent document 1 is preferably made of plastic.

[0005] However, due to the rigidity of plastic, there is a problem that even if the amount of wet sheets stored is reduced, a larger installation space than the actual wet sheets is still required. Furthermore, there is the issue that when the tissue paper container is discarded, its volume easily increases, leading to increased waste and thus being environmentally unfriendly. Summary of the Invention

[0006] The purpose of this invention is to provide a cover material for sheet packaging that can achieve space-saving and environmentally friendly sheet packaging, as well as a sheet packaging with a cover material.

[0043] Hereinafter, with reference to the accompanying drawings, embodiments of the sheet packaging cover material and the sheet packaging body with the cover material according to the present invention will be described in detail.

[0044] Furthermore, various technically preferred limitations have been added to the following embodiments for the purpose of implementing the present invention, but the scope of the present invention is not limited to the following embodiments and the illustrated examples.

[0045] Additionally, the following, such as Figure 1 As shown, the description will focus on defining the vertical, horizontal, and front-back directions, as well as the X, Y, and Z axes. Specifically, in the sheet packaging 100 with a cover, the side where the first end seal 111 is formed is designated as "upper," the side where the second end seal 111 is formed is designated as "lower," the left-hand side when the first end seal 111 is positioned on the upper side is designated as "left," the right-hand side is designated as "right," and one of the directions perpendicular to the vertical and horizontal directions is designated as "front," and the other as "back." Furthermore, the axis along the front-back direction is designated as the X-axis, the axis along the horizontal direction as the Y-axis, and the axis along the vertical direction as the Z-axis.

[0046] [Sheet packaging with lid]

[0047] like Figure 1 As shown, in this embodiment, the sheet packaging body 100 with a lid is, for example, fitted with a sheet packaging body lid 120 to cover the opening of a film-shaped sheet packaging body 110 that packages multiple rolls of sheet P. Furthermore, in use, as... Figure 2 As shown, the sheet P inside the sheet package 110 can be removed by opening the cover portion 121a of the cover component 121.

[0048] [Sheet]

[0049] Sheet P is wound into a roll within sheet packaging 110 along the Z-axis (height direction), and perforations are applied at constant intervals along its length. Sheet P is then cut along these perforations. Sheet P can be, for example, a wet sheet impregnated with a medicinal solution. Alternatively, it can be a wet wipe, kitchen cleaner, toilet cleaner, antiperspirant sheet, etc.

[0050] The sheet material of sheet P is preferably a nonwoven fabric made of a specified fiber, such as a nonwoven fabric manufactured by known techniques such as hydroentangling, hot air method, air-laid web method, dot bonding method, spinning bonding method, needle punching method, etc.

[0051] Examples of specified fibers include, for instance, cellulose fibers such as rayon, lyocell, Tencel, and cotton; polyolefin fibers such as polyethylene, polypropylene, and polyvinyl alcohol; polyester fibers such as polyethylene terephthalate and polybutylene terephthalate; and polyamide fibers such as nylon. These fibers can be used alone or in combination of two or more.

[0052] Furthermore, any solution can be used as the immersion solution for sheet P, depending on the intended use of sheet P. However, for example, a solution containing purified water, preservatives, pH adjusters, surfactants, etc., is preferred.

[0053] Furthermore, sheet P is not limited to wet sheet; it can also be dry sheet.

[0054] [Sheet Packaging]

[0055] like Figure 1 as well as Figure 2 As shown, the sheet packaging 110 is formed into a bag shape from a flexible sheet-like film.

[0056] As a sheet-like film, it can be made of single materials or composite materials of synthetic resin films such as polyethylene, polypropylene, polyethylene terephthalate, polyester, polyamide, and polyvinyl chloride, or composite films formed by laminating these synthetic resin films with aluminum foil or paper. Furthermore, the thickness of the sheet packaging 110 is preferably 40 μm to 70 μm.

[0057] The sheet packaging 110 joins the opposite edges of the sheet film to form a central sealing portion (not shown) (formed on the rear side of the sheet packaging 110), and then, after placing the rolled sheet P inside the cylindrical film, the holes at both ends of the cylindrical film are joined to form two end sealing portions 111, 111, thereby forming a pillow-shaped packaging body containing multiple sheets P.

[0058] The size of the sheet package 110 is determined based on the size of the rolled sheet P contained therein. However, in order to avoid unnecessarily increasing the size of the sheet package 110 and to ensure that the removal of the sheet P during use is not difficult, it is preferable to have a size that can accommodate multiple sheets P with some margin.

[0059] (Hanging hole)

[0060] At least one of the two end sealing portions 111, 111, which are the ends of the sheet packaging body 110, is provided with a hanging hole 11 for suspending the sheet packaging body 100 with the cover material on a designated hanging member.

[0061] The hanging hole 11 functions as a hook for attaching to a specified suspension component such as a hook. In particular, if the hanging hole 11 on the first end side is hooked to a hook installed on a wall or the like, the end sealing portion 111 on the second end side of the sheet packaging body 110 can face downwards, and the sheet packaging body 100 with a cover can be suspended by the hook or the like.

[0062] In addition, the end sealing portion 111 of the sheet packaging body 110 can also be part of the hook portion, and the hook portion is formed by the end sealing portion 111 and the hanging hole 11.

[0063] [Lid material for sheet packaging]

[0064] The sheet packaging cover 120 maintains the airtightness of the sheet packaging 110 and serves as a cover for removing the sheet P stored inside the sheet packaging 110 as needed. The sheet packaging cover 120 is formed in a removable manner to close the opening of the sheet packaging 110, such as... Figure 3 as well as Figure 4 As shown, the sheet packaging cover 120 has at least a cover component 121 and an assembly component 122.

[0065] Furthermore, as the cover material 120 for the sheet packaging body, any material that has a certain strength, such as polyethylene, polypropylene, polyethylene terephthalate, or ABS resin, and is resistant to the wetting of alcohol or liquid medicine contained in the sheet P when it is a wet sheet, can be a known material.

[0066] (Cover component)

[0067] like Figure 3 As shown, the cover component 121 is, for example, a circular component when viewed from above, and has a cover portion 121a on its upper surface. This cover portion 121a is a cover that closes the extraction hole 121d (described later). Additionally, as... Figure 4 As shown, the lower part of the inner surface of the side portion has a cylindrical internal thread portion 121b that engages with the external thread portion 1221c (described later), and the extraction portion 121c is provided in the hole of the internal thread portion 121b.

[0068] (Removal section)

[0069] like Figure 5A As shown, the extraction part 121c is a generally cylindrical component made of elastically deformable materials such as styrene-butadiene, polyester, polyethylene, or polyurethane elastomers. The extraction part 121c is configured such that, compared to the central portion of the extraction hole 121d, which in particular forms a hole for extracting the sheet P, the peripheral portion has a thicker wall. This extraction part 121c is fixed within the hole of the cover component 121.

[0070] (Removal hole)

[0071] As for the extraction hole 121d, it can be formed into any shape as long as resistance can be applied when extracting the sheet P, so that the sheets can be extracted one by one. However, for example, Figure 5A As shown, the preferred configuration is two straight lines intersecting in a cross shape, with a first circular portion provided at the intersection of the first ends of the lines, and a second circular portion with a smaller diameter than the first circular portion provided at the second end of the lines. This structure balances the retention of the sheet P in the extraction hole 121d with the ease of removing the sheet P.

[0072] The extraction section 121c is formed of an elastically deformable material as described above around the extraction hole 121d, thereby applying appropriate resistance to the sheet P and serving to hold the next sheet P after it has been extracted from the sheet packaging body 110. Furthermore, the sheet P can be cut using a perforated wire provided on it.

[0073] (Assembly components)

[0074] Assembly component 122 is a component used to assemble the cover component 121 onto the sheet packaging body 110. For example... Figure 4 As shown, the assembly component 122 includes a fixing component 1221 and a wheel-shaped component 1222. The fixing component 1221 is, for example, a component that is circular when viewed from above, and the wheel-shaped component 1222 is a component that is slightly smaller than the fixing component 1221 and is circular when viewed from above.

[0075] (Fixed components)

[0076] like Figure 5B As shown, the fixing member 1221 is configured such that a circular component, when viewed from above, is cut into semicircles of equal size. The first ends of the outer surfaces of the two semicircles are connected to each other by a connecting portion 1221a that is thinner than the fixing member 1221. Therefore, the fixing member 1221 can be opened and closed freely with the connecting portion 1221a as a fulcrum.

[0077] In addition, such as Figure 4 as well as Figure 5B As shown, the fixing member 1221 has a recess 1221b on the lower part of the inner surface side of the side side portion that abuts against the protrusion 1222a (described later) of the wheel-shaped member 1222, and has an external thread portion 1221c from the upper end of the outer surface side portion.

[0078] (Wheel-shaped component)

[0079] like Figure 5C As shown, the outer diameter of the wheel-shaped component 1222 is larger at the bottom than at the top, and the upper part of the outer surface side of the side portion has a protrusion 1222a that abuts against the recess 1221b. In addition, pinching portions 1222b and 1222b are provided at the opposing portions at the lower end of the wheel-shaped component 1222 in a downwardly projecting manner. These pinching portions 1222b and 1222b are used to pinch the wheel-shaped component 1222 with fingers without contacting the protrusion 1222a when the sheet packaging cover 120 is installed on the sheet packaging body 110.

[0080] (Sealing component)

[0081] like Figure 5B As shown, the sealing member 123 is, for example, an elastic member such as rubber provided at the lower end of the external thread portion 1221c. The sealing member 123 abuts against the lower end of the cover member 121, thereby improving the tightness of the seal between the cover member 121 and the assembly member 122, and improving the airtightness within the sheet packaging body 110.

[0082] Furthermore, when the cover member 121 and the assembly member 122 are in the shape shown in this embodiment, the sealing member 123 may also be provided at the lower end of the internal thread portion 121b. However, since the resistance increases when the internal thread portion 121b is screwed into the external thread portion 1221c, it is preferable to provide it at the lower end of the external thread portion 1221c.

[0083] (Installation method for cover material for sheet packaging)

[0084] When installing the sheet packaging body cover 120 as described above onto the sheet packaging body 110, follow the sequence shown in (1) to (3) below.

[0085] (1) In a portion of the sheet packaging 110 (in Figure 1 as well as Figure 2 An opening of a predetermined size is provided at approximately the center of the end sealing portion 111 on the second end side. The wheel-shaped component 1222 is inserted into the opening, such that the sheet packaging body 110 around the opening abuts against the outer surface of the wheel-shaped component 1222. At this time, the gripping portions 1222b and 1222b are held by the fingers of one hand, and one end of the sheet P is pulled out from the hole of the wheel-shaped component 1222 by the other hand.

[0086] (2) Using the connecting part 1221a as a fulcrum, open the fixing part 1221, clamp and close the wheel-shaped part 1222 from above the sheet packaging body 110, so that the protrusion 1222a abuts against the concave part 1221b.

[0087] (3) After one end of the sheet P comes out from the take-out hole 121d, the cover part 121 is rotated so that the internal thread part 121b engages with the external thread part 1221c until the sealing part 123 abuts against the lower end of the cover part 121, thereby closing the whole.

[0088] [The effects of the invention]

[0089] The sheet packaging body cover 120 of this embodiment is installed by covering the opening provided in the sheet packaging body 110. Figure 1 The sheet packaging 100 with a lid shown can be used as a container for storing sanitary tissues.

[0090] In the sheet packaging 100 with a lid according to this embodiment, the sheet packaging 110, which is equivalent to a conventional plastic container for storing rolled-up sheets of sanitary tissues, is made of a flexible sheet-like film. Therefore, the sheet packaging 110 can be slightly deformed and can be placed in the gaps of a shelf, thus achieving space saving and easy portability.

[0091] Furthermore, the cover 120 for the sheet packaging body is separate from the sheet packaging body 110 and can be easily installed and removed. Therefore, when all the sheets P stored in the sheet packaging body 110 are used up, the cover 120 for the sheet packaging body can be removed, and only the sheet packaging body 110 needs to be discarded. This eliminates the need for the traditional bottle-shaped tissue paper storage container, reducing plastic waste and making it more environmentally friendly.

[0092] Furthermore, the cover material 120 for the sheet packaging body has a take-out portion 121c, which has a take-out hole 121d. Therefore, the end of the sheet P taken out from the sheet packaging body 110 can be properly held, and the sheet P can be properly taken out by applying resistance.

[0093] Furthermore, a hanging hole 11 is provided on the end sealing portion 111 at at least the first end side of the sheet packaging body 110. Therefore, by hooking the hanging hole 11 onto a hook or the like, the sheet packaging body 100 with the cover material can be suspended by the hook or the like.

[0094] Such a sheet packaging body 100 with a lid can be hung by fixing hooks or the like in places easily accessible to users, such as kitchens and bathrooms, and the hook with the hanging hole 11 can be hung on the hooks or the like.

[0095] Furthermore, for example, when the hook 11 of the end seal 111 on the first end side is hooked onto a hook, if the end seal 111 on the second end side is fitted with a cover 120 for the sheet packaging, the hook or the like will exert an upward force on the sheet packaging 100 with the cover, relative to the downward force the user wants to remove the sheet P. Therefore, the user can remove the sheet P with one hand without holding the sheet packaging 110 in place.

[0096] In addition, the cover material 120 for the sheet packaging body has a sealing member 123 that makes the cover member 121 and the assembly member 122 airtight. Therefore, when the cover member 121 is assembled to the assembly member 122, the tightness of the two members can be improved, and when the sheet P stored in the sheet packaging body 110 is a wet sheet, the evaporation of the liquid medicine can be further suppressed.

[0097] [Modification; Cover material for sheet packaging]

[0098] The above example illustrates a case where the cover component 121 and the assembly component 122, which are independent parts, are combined to form a cover material 120 for a sheet packaging body, but the example is not limited to this. For example, other methods may also be used. Figure 6 The sheet packaging cover material 120 is an integral part of the downward protruding cover component 121 shown and the clip-like assembly component 122 that can rotate freely in the left and right direction and hold the cover component 121.

[0099] Furthermore, the cover 121a only needs to be able to close the extraction hole 121d, and is not limited to the openable cover fixed to the upper surface of the cover member 121 as shown in FIG. 5. For example, it could also be Figure 6 The cover shown is a modular design that allows for easy assembly and disassembly.

[0100] In the case of such a sheet packaging cover 120, an opening is provided in the sheet packaging 110, the lower part of the cover member 121 protruding from the assembly member 122 is inserted into the sheet packaging 110, and the opening of the sheet packaging 110 is clamped by the assembly member 122, thereby enabling the sheet packaging cover 120 to be installed in the sheet packaging 110.

[0101] When the sheet packaging cover 120 is in this shape, the sheet packaging cover 120 is installed on the sheet packaging body 110 by clamping the sheet packaging body 110 with the assembly component 122, thereby reducing the deformation of the sheet packaging body 110 around the sheet packaging cover 120.

[0102] Furthermore, in the above description, the cover component 121, the fixing component 1221 constituting the assembly component 122, and the wheel-shaped component 1222 are separate and independent components, but are not limited to this. For example, the cover component 121, which is integral with the fixing component 1221, may have an internal thread from the lower end of its inner side, and the wheel-shaped component 1222 may have an external thread that engages with the internal thread from the upper end of its outer surface. By using the cover component 121 and the wheel-shaped component 1222 to clamp the sheet packaging body 110 around the opening, the sheet packaging body is installed with the cover material 120 onto the sheet packaging body 110.

[0103] Furthermore, the three methods described above are merely examples. The cover material 120 for sheet packaging includes a cover component 121 and an assembly component 122 for mounting the cover component 121 to the sheet packaging 110. The cover component 121 includes a removal portion 121c, a removal hole 121d that applies resistance when removing the sheet P, and a cover portion 121a. By closing the removal hole 121d, the cover can be easily mounted to the sheet packaging 110 to close the opening of the film-shaped sheet packaging 110 in which the rolled sheet P is housed. Therefore, any shape and mounting method can be appropriately used.

[0104] [Variations; Other Structures]

[0105] In the above, hooks or the like are used as hanging components, but this is not the only option. For example, the hanging hole 11 can be hooked onto a protrusion pre-set on the wall, a nail driven into the wall, a rivet, etc., to hang the sheet packaging 100 with the cover material.

[0106] Furthermore, the hook portion of the sheet packaging body 100 with a lid is not limited to the hanging hole 11. For example, it can be a resin ring fixed to the end sealing portion 111, etc., as long as it is a component used to hang the sheet packaging body 100 with a lid on the wall, it can be anything.

[0107] In addition, Figure 1 as well as Figure 2 An opening is provided by cutting approximately the central portion of the end seal portion 111 on the second end side of the sheet packaging body 110, but it is not limited to this. For example, one end of the end seal portion 111 may be cut off, or the entire end seal portion 111 may be cut off.

[0108] In this embodiment, the sheet P is shown as being wound into a roll along the Z-axis (vertical direction), so an opening is provided at the end sealing portion 111, but it is not limited to this. For example, the sheet P may also be wound into a roll along the X-axis (front-back direction), in which case it is preferable to provide an opening for the sheet P on the front surface of the sheet packaging body 110.

[0109] However, for example, even though the sheet P is stored in a rolled-up state along the Z-axis within the sheet packaging 110, it is difficult for the user to remove the stored sheet P if an opening is provided on the front surface of the sheet packaging 110. Therefore, it is preferable to pre-provide an opening in the sheet packaging 110, attach a peelable seal to cover the opening, and mark the cut portion of the sheet packaging 110 on the sheet packaging 110.

[0110] In addition, it goes without saying that, in addition to these, appropriate changes can be made to the specific details of the structure.
