Description

Technical Field

[0001] The present invention relates to a package used for packaging a sheet-like object.

Background Art

[0002] A wet tissue, which is a wet sheet obtained by impregnating a fiber material such as paper, woven fabric, or non-woven fabric with a chemical solution containing alcohol, a humectant, a surfactant, etc., is stored in a packaging container having airtightness and water impermeability so as not to dry out. There are various wet sheets, such as those for wiping dirt off the skin, removing makeup, wiping an infant's bottom, and wet sheets for cleaning. These wet sheets are made into products by storing them in a package having airtightness and water impermeability so that the contained chemical solution does not dry out. An outlet is formed at a substantially central portion on the surface of such a package, and a lid member is repeatedly attached to the upper surface of this outlet so as to be openable / closable and sealable.

[0003] For example, Patent Document 1 describes a packaging container for a wet tissue, which is particularly composed of a container body made of a plastic resin and an opening / closing lid, and has an opening / closing mechanism for opening and closing the opening / closing lid by utilizing the elasticity of a resin spring. In the invention according to Patent Document 1, a special member such as a locking pin member is not required to lock an elastic plate to the main body container, the structure is simple, assembly is easy, and it is said that a packaging container for a wet tissue that does not require sorting at the time of disposal can be obtained.

[0004] However, in recent years, due to the increasing awareness of environmental problems, it has been required to reduce the use of these plastic materials and synthetic resin materials. From such a perspective, for example, it is preferable to use a paper member, and in some cases, paper packaging containers are manufactured and used.

[0005] In the case of such a paper packaging container, for example, a box-shaped packaging container is formed by bending a paper member. At this time, folding marks remain on some sides. Such remaining folding marks are not preferable in terms of appearance (aesthetic appearance).

Modes for Carrying Out the Invention

[0016] Hereinafter, the package according to the present invention will be described in detail. Note that the present invention is not limited to the following examples and can be arbitrarily changed without departing from the gist of the present invention.

[0017] FIG. 1 is a perspective view showing an example of a package according to an embodiment of the present invention. One aspect of the present invention includes a main body 10 for storing a laminate of sheet-like materials, an outlet 5 for taking out the sheet-like material from the main body 10, and a lid member 20 that is repeatedly attachable and detachable to cover the outlet 5. The main body 10 is a box-shaped container formed by folding the vicinity of both ends of a material mainly made of paper into a cylindrical shape to form side surfaces, and is characterized in that the folded-over portion 30 after folding is covered with a sealing member 40. This is the package 1.

[0018] In one aspect of the present invention, the main body 10 is formed in a box shape, and the lid member 20 is formed on the upper surface of the box-shaped main body 10. As an example, as shown in FIG. 1, the main body 10 is a cardboard box and is formed in a sealed structure except for the outlet 5, and a lid member 20 for opening and closing the outlet 5 is provided on the upper surface portion 15 of the main body 10. Also, inside the main body 10, a laminate of wet sheets, such as a laminate of sheet-like materials such as wet tissues, is stored so that it can be fed out one by one. Note that the package 1 according to the present invention mainly targets wet sheets, but may also be applied to the packaging of dry sheets.

[0019] Also, the main body 10 may directly package the laminate of sheet-like materials, or may be, for example, one having a box-shaped main body on the exterior of a pillow-type package.

[0020] The main body 10 has a size and shape capable of accommodating a laminate of sheet-like materials. As described above, the main body 10 is formed of a material mainly composed of paper. As the paper constituting the main body, for example, appropriate paper members having a predetermined thickness and strength, such as cardboard, composite materials including paper layers, synthetic paper, etc. are used. The main body 10 is, for example, in the shape of a cube or a rectangular parallelepiped box as shown in FIG. 1, with a front portion 11, a left side portion 12, a back portion 13, a right side portion 14 formed in four directions, an upper surface portion 15 connecting the upper ends thereof, and a bottom surface portion 16 connecting the lower ends and facing the upper surface portion 15 in the vertical direction.

[0021] The sheet-like material accommodated in the package 1 is a non-woven fabric made of pulp, cotton, synthetic fibers, etc., paper made of natural pulp, synthetic pulp, etc., or a fiber material having wet strength such as cloth like gauze, impregnated with liquid components such as water, alcohol, fragrance, lotion, medicine, surfactant, or a solution. The laminate of sheet-like materials is such that the individual sheets overlap and are folded, and may be stored in the package in a so-called pop-up type that allows the wet tissue to be continuously taken out from the outlet of the package, or may be a so-called single-sheet type in which the folded wet tissues are stacked without overlapping. The wet sheet accommodated in the package may be a face mask, makeup remover, baby wipe, wet sheet for cleaning, etc.

[0022] An outlet 5 for taking out the sheet-like material is formed in the upper surface portion 15 of the main body 10. The outlet 5 is formed, for example, at the center of the upper surface portion 15 and has a size sufficient for taking out the sheet-like material. When storing a pillow package inside the box-shaped container, the outlet of the pillow package is arranged within the range of the outlet 5 of the main body 10 in plan view (when viewed from above).

[0023] As shown in FIG. 1, the outlet 5 formed in the main body 10 is formed at approximately the center of the upper surface of the main body 10. The outlet 5 is not particularly limited in shape as long as it can be covered entirely by the lid member 20 and the sheet-like object inside can be taken out. For example, it may be rectangular or elliptical. Further, the outlet 5 is not limited to the one formed in advance. The outlet 5 can also be formed by making a perforation for forming the outlet 5 in the main body 10, or by leaving only several connection points and making a cut, or by making a cut to a thickness that can be cut off, so that the outlet 5 portion of the main body 10 can be cut off. When a perforation or the like is provided in the main body 10, the portion that becomes the outlet 5 is attached to the lid member 20 by an adhesive applied to the surface of the lid member 20 facing the main body 10. Then, when the wet sheet is used for the first time, by peeling the lid member 20 from the main body 10, the portion that becomes the outlet 5 together with the lid member 20 is cut off from the main body 10, and the outlet 5 is formed.

[0024] For example, a lid label 20 formed in a label shape as shown in FIG. 1 is used as the lid member 20. As an example, the lid label 20 is adhered to the upper surface at the side portion 21 close to one side of the main body 10 by an adhesive or the like. Further, the lid label 20 has, for example, a knob portion 22 protruding in a mountain shape at the end portion on the opposite side of the above-mentioned adhesion portion. No adhesive is provided on the back side of the knob portion 22. An adhesion portion is provided in the region on the back side of the lid label 20 facing the peripheral portion. Thereby, the lid label 20 can be repeatedly peeled and adhered to the upper surface portion 15 of the main body 10. The adhesion portion enables the lid label 20 to be pasted and peeled from the upper surface portion 15 any number of times. That is, the lid label 20 is configured to cover the outlet 5 and be repeatedly opened and closed.

[0025] Although not shown in FIG. 1, the lid label 20 may have a stopper near the side portion 21 close to one side of the main body portion 10 so that the lid label 20 cannot be completely peeled off by the user during the peeling operation. The stopper is formed by providing a cut near the side portion 21 of the lid label 20. The shape of the stopper may be an inner hook type stopper with a cut provided inside the lid label 20, or an outer hook type stopper with a cut provided from the outer edge of the lid label 20 toward the inside. The cut of the stopper is formed by combining a linear shape and a curved shape, and has a role of stopping the peeling of the lid label 20 when the lid label 20 is peeled from the main body portion 10.

[0026] In addition, in one aspect of the present invention, instead of the lid member 20 as the lid label described above, a lid member 20 in which a substrate portion and a lid portion are connected via a hinge portion may be used. Such a lid member 20 is attached, for example, facing the outlet 5 provided on the upper surface of the main body portion 10. That is, it can be attached by adhering the upper surface of the substrate portion of the lid member 20 to the lower surface of the peripheral edge portion of the outlet 5 of the main body portion 10. Alternatively, it may be installed so that the bottom of the substrate portion is adhered to the upper surface of the main body portion 10.

[0027] In one embodiment of the present invention, the main body portion 10 and the lid member 20 are formed of a material mainly composed of paper. When composed only of pure paper members, the weight ratio is about 100%. However, in the case of a composite material including a paper layer and other member layers, or synthetic paper, etc., it is desirable that the material mainly composed of paper is 20% or more paper by weight ratio. Alternatively, in one aspect of the present invention, the material mainly composed of paper may be 50% or more paper by weight ratio. If 50% or more by weight ratio is paper, it can be treated as paper under the Resource Effective Utilization Promotion Act.

[0028] In addition, in one aspect of the present invention, the material mainly composed of paper is preferably a composite material composed of two or more materials and is configured such that the weight ratio of paper is the largest. Alternatively, it may be a composite material composed of three or more materials and is configured such that the weight ratio of paper is the largest.

[0029] As an example of the present invention, it is preferable that the main body 10 or the lid member 20 is a member in which a waterproof film is adhered to a paper member or a member coated with a waterproof resin layer. And, on the lower surface of such a coat layer, there is an adhesive layer formed by applying an adhesive capable of repeated adhesion and peeling to the main body 10, i.e., an adhesive that can be re - adhered and re - peeled. Note that the adhesive layer may not be formed in the portion facing the outlet 5, or a member having the shape of the outlet 5 may be pasted. In addition, on the surface opposite to the layer made of the paper member, predetermined characters, figures, etc. are printed, and there may further be a printed adhesive layer coated with an adhesive for laminating a protective layer, or a protective layer for protecting the printed surface.

[0030] The coat layer is a layer made of a waterproof film or a waterproof resin layer. As an example, polyethylene terephthalate (PET) can be mentioned, but it is not particularly limited as long as it is a film or resin material having a waterproof function. Also, for the adhesive layer, for example, pressure - sensitive adhesives such as polyester - based, acrylic - based, rubber - based adhesives are used.

[0031] In one aspect of the present invention, the basis weight of the paper member is 30 g / m 2 or more and 400 g / m 2 or less, the thickness of the waterproof film is preferably 7 μm or more and 50 μm or less, and the thickness of the waterproof resin layer is preferably 3 μm or more and 50 μm or less.

[0032] Next, the mode of formation of the side portions 12 and 14 of the package 1 in the present invention and the mode of covering the folded portion 30 after folding with the sealing member 40 will be described respectively. FIGS. 2 and 3 are partial development views showing an example of the folding method for forming the package according to an embodiment of the present invention. (A) is a view seen from the upper surface side, and (B) is a view seen from the bottom surface side. In FIGS. 2 and 3, the dashed-dotted line indicates a mountain fold, and the broken line indicates a valley fold. FIG. 4 is a view showing the mode of the folded portion on the side surface of the package according to an embodiment of the present invention. (A) is a view showing the folded portion formed by the folding method of FIG. 2, and (B) is a view showing the folded portion formed by the folding method of FIG. 3.

[0033] The package 1 according to an embodiment of the present invention is generally formed of a material mainly composed of paper. By folding the vicinity of both ends of the material formed into a cylindrical shape with paper as the main component as the folded portion, the side portions 12 and 14 are formed. The cylindrical shape can be formed, for example, by connecting (adhering) the opposing long sides of a material mainly composed of a single sheet of paper, and creases are formed so that the opening of the cylinder is rectangular. Thereby, the four surfaces of the front portion 11, the upper surface portion 15, the back portion 13, and the bottom surface portion 16 of the package 1 are formed, and the left side portion 12 and the right side portion 14 can be in a cylindrical state with rectangular openings. It is preferable to form the outlet 5 of the upper surface portion 15 at an initial stage.

[0034] Next, as shown in FIGS. 2 and 3, the side portions are formed by folding the vicinity of both ends as the folded portion. The folded portion 30 near the ends is composed of a margin portion 31 and a folded portion 32 as shown in FIGS. 2 and 3. By adhering the open sides of the ends using the margin portion 31 and folding with the folded portion 32, a side portion as shown in FIG. 4 is formed.

[0035] The side portions 12 and 14 shown in Fig. 4(A) are formed by the folding methods shown in Figs. 2(A) and (B). The folding method shown in Fig. 4(A) can be seen, for example, in a paper pack beverage container, and a triangular folding mark 35 is formed. In Fig. 4(A), the triangular folding mark 35 is finally folded back to the side portions 12 and 14 side, but it may be folded back to the front portion 11 and the back portion 13 sides on the opposite side respectively.

[0036] Also, the side portions 12 and 14 shown in Fig. 4(B) are formed by the folding methods shown in Figs. 3(A) and (B). The folding method shown in Fig. 4(B) can be seen in a pillow-type packaging container, etc., and the side portions 12 and 14 are formed by folding back the portion that was originally the adhesive margin 31 to the upper or lower side of the side portions.

[0037] Fig. 5 is a view showing the covering mode of the seal member 40 in the package 1 according to an embodiment of the present invention. (A) is a perspective view showing the mode of covering the corner portion on the side surface side, and (B) is a perspective view showing the mode of covering the entire side portion.

[0038] When the side portions 12 and 14 are formed by the above-described folding method, since the folding marks remain on the side portions 12 and 14, the appearance is not good, and also, it is not possible to perform displays such as explanatory texts on the side portions 12 and 14. Therefore, in the present invention, the folding margin portion 30 is covered with the seal member 40. Thereby, since the joint surface after folding can be hidden by sealing, the appearance can be improved, and also, the strength as a container can be improved. Furthermore, even on the side portions 12 and 14 having folding marks, it is possible to form a printing surface for display items and the like.

[0039] The seal member 40 is not particularly limited, but for example, a sheet-like or film-like member having an adhesive surface on one side can be used. As an example, single materials or composite materials of synthetic resins such as paper, synthetic paper, polyethylene terephthalate, polyethylene, polypropylene, polyester, polyamide, and polyvinyl chloride can be mentioned.

[0040] As an example of the covering by the sealing member 40, as shown in FIG. 5(A), the sealing member 40 may cover the corner of the package 1. For example, when the adhesive margin 31 as shown in FIG. 4(B) is folded upward or downward to form the side faces 12 and 14, the sealing member 40 can be provided at the corner to cover a part thereof. In FIG. 5(A), only the right corner of the front face 11 is shown with the sealing member 40, but it is preferable to cover all four corners, i.e., the left corner of the front face 11 and the left and right corners of the back face 13, with the sealing member 40.

[0041] Also, in one aspect of the present invention, as shown in FIG. 5(B), all of the side faces 12 and 14 may be covered with the sealing member 40. For example, it is desirable to cover the entire side faces 12 and 14 having the triangular fold lines 35 as shown in FIG. 4(A) with the sealing member 40. In this way, it becomes possible to perform displays such as printing on the side surface side. Also, in this case, not only the side faces 12 and 14 but also the front face 11, the back face 13, etc. may be covered with the sealing member, and three or more of the front face 11, the back face 13, the left side face 12, and the right side face 14 may be covered. By doing so, the strength of the entire package 1 can be improved and the appearance can also be enhanced.

[0042] FIG. 6 is a perspective view showing an example of another package according to an embodiment of the present invention. Another aspect of the present invention includes a main body portion 10 for storing a laminate of sheet-like materials, an outlet 5 for taking out the sheet-like materials from the main body portion 10, and a lid member 20 that is repeatedly openable and closable and covers the outlet 5. The main body portion 10 is a pillow-type package in which both ends of a cylindrical material mainly composed of paper are closed, and the adhesive margins 31 formed at the closed both ends are folded upward or downward, and the folded adhesive margins 31 are covered with a sealing member 40, which is a package 2.

[0043] So far, the box-shaped container has been described. However, the packaging body 2 according to an embodiment of the present invention can also be applied to a so-called pillow-type flexible packaging. In the pillow-type packaging body 2, a margin portion 31 for closing both ends is formed. After folding the margin portion 31 upward or downward, it can be covered with the sealing member 40 in the same manner as the above-described mode. In FIG. 6, the four corners on the side surface side are covered, but the entire surface of the margin portion 31 may be covered in the same manner as described above.

[0044] As described above, according to the present invention, it is possible to obtain a packaging body that is excellent in appearance and has improved strength as a container.

[0045] Although the embodiment and each example of the present invention have been described in detail as above, it will be easily understood by those skilled in the art that many modifications can be made without substantially departing from the novel matters and effects of the present invention. Therefore, all such modified examples are intended to be included within the scope of the present invention.

[0046] For example, in the specification or the drawings, a term that is described at least once together with a broader or synonymous different term can be replaced with that different term at any location in the specification or the drawings. Also, the configuration of the packaging body is not limited to that described in the embodiment and each example of the present invention, and various modified implementations are possible.
