Description

[Technical field]

[0001] The present invention relates to a sheet wrapping body and a case body. [Background technology]

[0002] Patent Document 1 discloses a tissue paper aggregate package in which a plurality of tissue paper rolls are wrapped in an exterior film in a gusset shape, while Patent Document 2 discloses a toilet roll package in which a scented toilet roll, which is made by wrapping a strip of toilet paper around a paper tube to which a fragrance has been applied, is packaged in a resin film.

[0003] In recent years, a distribution form in which these sheet packages are packed in a plurality of boxes such as cardboard cases without handles and transported, sold, etc., is becoming widespread. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-199530 A [Patent Document 2] Patent Publication No. 2021-54517 Summary of the Invention [Problem to be solved by the invention]

[0005] However, sheet packages packed in a box in multiple units without handles do not have air holes that are provided at the same time as handles are added in the past to allow air to escape, making it difficult to escape the air inside the packaging bag and difficult to wrap the sheet packages in film.Furthermore, it is difficult to insert multiple sheet packages into a case and difficult to pull out the sheet packages out of the case.

[0006] An object of the present invention is to provide a sheet package that is not provided with a handle and that can be easily wrapped, inserted into a case, and removed from the case even when multiple pieces are packed in a box. [Means for solving the problem]

[0007] The first aspect of the present invention is a sheet packaging body in which a plurality of sanitary thin paper products are contained in a packaging bag, the sheet packaging body having no handle portion, the packaging bag having an air hole formed above half the height of the sheet packaging body, and the sheet packaging body having multiple units contained in a case. to provide.

[0008] In the first aspect, when a sheet packaging body in which multiple sanitary thin paper products are contained in a packaging bag is not provided with a handle and multiple units are contained in a case, air holes are provided in the packaging bag and formed above half the height of the sheet packaging body, which makes it easier for air to escape from the packaging bag. Therefore, according to the first aspect, even when no handle is provided and multiple units are packed in a box, the sheet packaging body can be easily packaged, inserted into the case, and removed from the case.

[0009] A second aspect of the present invention is the sheet packaging body according to the first aspect, wherein the air hole is formed at a position corresponding to the boundary between two adjacent sanitary thin paper products. In this specification, the "corresponding position" refers to a part of the packaging bag that faces the target area of ​​the sanitary thin paper product when the sanitary thin paper product is contained in the packaging bag.

[0010] In the second aspect, the air hole is formed at a position corresponding to the boundary between two adjacent sanitary thin paper products, which makes it easier for air trapped in the small space formed between the two adjacent sanitary thin paper products and the packaging bag to escape. Therefore, in the second aspect, regardless of the shape or packaging manner of the sanitary thin paper products, even when no handles are provided and multiple products are packed in a box, the sheet packaging body can be easily packaged, inserted into a case, and removed from the case.

[0011] A third aspect of the present invention is a sheet packaging body according to the first or second aspect, wherein a seal portion for closing the packaging bag is provided on the top surface of the packaging bag, and the air hole is formed in the seal portion.

[0012] In a third aspect, when a seal portion for closing the packaging bag is provided on the top surface of the packaging bag, an air hole can be formed in such a seal portion, making it easier for air to escape through the air hole while preventing dust from entering the packaging bag.

[0013] A fourth aspect of the present invention is a sheet packaging body described in any one of the first to third aspects, wherein the sanitary thin paper product is a sanitary thin paper roll in which sanitary thin paper is wrapped around a paper tube.

[0014] In the fourth aspect, even if the sanitary thin paper product is such a sanitary thin paper roll, the air can be easily removed from the packaging bag, making it easier to wrap the sheet packaging body, insert it into a case, and pull it out from the case.

[0015] Furthermore, when the sanitary thin paper product is a sanitary thin paper roll, the curved surface of the sanitary thin paper roll forms a large space in the area surrounded by two or more sanitary thin paper rolls and the packaging bag, and forming an air hole in a position corresponding to that space increases the amount of air passing in and out of the air hole, making it easier for dust to enter the packaging bag through the air hole. In contrast, in the fourth aspect, the air hole is formed in a position corresponding to the boundary between two adjacent sanitary thin paper rolls, limiting the amount of air passing in and out of the air hole and preventing dust from entering the packaging bag through the air hole.

[0016] A fifth aspect of the present invention is the sheet packaging body according to the fourth aspect, wherein the air hole is not formed at a position corresponding to the space inside the cardboard tube.

[0017] When the sanitary thin paper product is a sanitary thin paper roll, a space is formed inside the paper tube of the sanitary thin paper roll, so if air holes are formed in a position corresponding to the space in the paper tube, when fragrance or deodorant is attached to the paper tube, the fragrance or deodorant component is likely to escape outside the packaging bag. In contrast, in the fifth aspect, the air holes are not formed in a position corresponding to the space inside the paper tube, so even when fragrance or deodorant is attached to the paper tube, it is possible to prevent the fragrance or deodorant component from escaping outside the packaging bag.

[0018] A sixth aspect of the present invention provides a sheet packaging body according to any one of the first to third aspects, wherein the sanitary thin paper product is an individually packaged body in which a sanitary thin paper laminate formed by stacking sanitary thin papers is contained in an individual packaging bag.

[0019] In the sixth aspect, even if the sanitary thin paper product is an individually packaged sanitary thin paper laminate like this, air can be easily removed from the packaging bag, making it easier to wrap the sheet packaging, insert it into a case, and remove it from the case.

[0020] A seventh aspect of the present invention is the sheet packaging body according to any one of the first to sixth aspects, wherein the air holes are formed on a side surface of the sheet packaging body.

[0021] In the seventh aspect, since the air holes are formed on the side surface of the sheet packaging body, dust is less likely to enter the packaging bag compared to when the air holes are formed on the top surface of the sheet packaging body.

[0022] An eighth aspect of the present invention is a case body in which a plurality of the sheet wrapping bodies according to any one of the first to seventh aspects are accommodated in the case.

[0023] In the eighth aspect, by forming a case body in which a plurality of the above-mentioned sheet wrapping bodies are housed in a case, the sheet wrapping bodies housed in the case have air holes in the packaging bag, and the air holes are formed above half the height of the sheet wrapping body, so that air can easily escape from the packaging bag. Therefore, according to the eighth aspect, even if the sheet wrapping body housed in the case does not have a handle, it is easy to insert it into and pull it out of the case. Effect of the Invention

[0024] According to one aspect of the present invention, it is possible to provide a sheet packaging body that does not have a handle and can be easily wrapped, inserted into a case, and removed from the case, even when multiple pieces are packed in a box. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In some cases, parts common to each drawing are given the same reference numerals and their explanations are omitted. In addition, the scale of each member in each drawing may differ from the actual scale.

[0027] In this specification, the directions of the drawings are described using a three-dimensional Cartesian coordinate system with three axial directions (X, Y, and Z). In each drawing, the left-right direction or width direction of the sheet packaging body is defined as the X direction, the front-rear direction or depth direction of the sheet packaging body is defined as the Y direction, and the up-down direction or height direction of the sheet packaging body is defined as the Z direction.

[0029] First Embodiment Fig. 1 is a diagram showing a first embodiment of a sheet packaging body. As shown in Fig. 1, the sheet packaging body 100 has a packaging bag 10 and a plurality of sanitary thin paper products 20 contained in the packaging bag 10.

[0030] As shown in Fig. 1, the packaging bag 10 has a top surface 11, a bottom surface 12, a front surface 13, a back surface 14, side surfaces 15, and side surfaces 16 when multiple sanitary thin paper products 20 are stored inside. In the packaging bag 10, the top surface 11 and the bottom surface 12 face each other in the up-down direction (Z direction), the front surface 13 and the back surface 14 face each other in the front-to-back direction (Y direction), and the side surfaces 15 and 16 face each other in the left-to-right direction (X direction). The side surfaces 15 and 16 are continuous with all of the top surface 11, the bottom surface 12, the front surface 13, and the back surface 14.

[0031] As shown in Fig. 1, the packaging form of the packaging bag 10 can be a gusset packaging in which a cylindrical resin film bag made with one end sealed is cut to a predetermined length, a sanitary thin paper product is inserted, and the other end is sealed. With this type of gusset packaging, the top surface 11 of the packaging bag 10 is provided with a seal portion 30 that closes the packaging bag 10. Note that, for ease of understanding, the seal portion 30 is shown in an upright position in Fig. 1, but normally it overlaps the top surface 11 of the packaging bag 10 in a fallen position.

[0032] The packaging form of the packaging bag 10 is not limited to such gusset packaging. Packaging forms other than gusset packaging may include, for example, packaging in which a sanitary thin paper product is wrapped in a sheet-like resin film, the resin film is made into a cylindrical shape, the flow direction is sealed, and then the resin film is folded into a gusset shape while sealing positions corresponding to both ends of the cylindrical resin film and cut off (pillow packaging), packaging in which both ends of the cylindrical resin film into which the sanitary thin paper product has been inserted are folded and sealed (sealed) (caramel packaging), or a combination of these may be used.

[0033] The material of the packaging bag 10 is, for example, a resin film, but is not limited to this and may also be paper, a biodegradable material (biodegradable plastics such as polylactic acid), or a biomass material (a renewable organic resource derived from living organisms, such as biomass film, excluding fossil resources).

[0034] The form of the resin film used in the packaging bag 10 is not particularly limited, and may be a single-layer film formed of a single layer of the above-mentioned resin, a laminate film in which the above-mentioned resin is laminated, a film in which the above-mentioned resin is bonded or laminated with pulp paper or nonwoven fabric, or a mixed film formed from a mixture of two or more of the above-mentioned resins.

[0035] When the packaging bag 10 is formed from a resin film, the material of the resin film is not particularly limited, and examples include polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and a laminate of PE-ethylene vinyl alcohol copolymer (EVOH)-PE (PE / EVOH / PE).

[0036] The thickness of the resin film is not particularly limited and can be from 10 μm to 70 μm, preferably from 15 μm to 60 μm, and more preferably from 20 μm to 50 μm.

[0037] There are no particular limitations on the form of the sanitary thin paper product 20. In the sheet packaging body 100 according to the first embodiment, the sanitary thin paper product 20 is a sanitary thin paper roll, as shown in FIG.

[0038] The dimensions of the sanitary thin paper roll 20 are not particularly limited, but for example, the roll width in the width direction (Z direction) is 85 mm or more and 500 mm or less, and the roll diameter in the radial direction (X direction or Z direction) is 80 mm or more and 200 mm or less.

[0039] As shown in Figs. 1 and 2, the sanitary thin paper roll 20 has a long sanitary thin paper 22 wound around a hollow core 21.

[0040] The hollow core 21 is a cylindrical winding core. The hollow core 21 also includes a structure without a winding core (coreless structure). The material of the hollow core 21 is not particularly limited, and paper, resin, etc. can be used.

[0041] The form of the hollow core 21 is not particularly limited, and for example, a cardboard tube can be used. This cardboard tube 21 may be made of either a single layer of cardboard or multiple layers of cardboard, and may be a coated cardboard base paper that has been printed on or coated with a fragrance or deodorant in advance. In addition, the way in which the cardboard tube is wound is not particularly limited, and for example, it may be either a flat winding or a spiral winding (so-called spiral cardboard tube), etc.

[0042] In this embodiment, the hollow core is a cardboard tube 21 made of multiple layers of cardboard wound in a spiral shape and coated with a fragrance.

[0043] The dimensions of the hollow core 21 are not particularly limited. For example, the length of the hollow core 21 in the longitudinal direction (Y direction) is approximately the same as the roll width in the width direction (Z direction) of the roll 20 (85 mm to 500 mm). In addition, the diameter dimension of the hollow core 21 in the radial direction (X direction or Y direction) is 33 mm to 50 mm, preferably 35 mm to 45 mm.

[0044] The long sanitary thin paper 22 is wound in the circumferential direction around a hollow core (paper tube) 21. The number of plies of the long sanitary thin paper 22 is not particularly limited, but can be one or more plies, and is preferably one or two plies.

[0045] The uses of the sanitary thin paper 22 are not particularly limited, and examples thereof include toilet paper, kitchen paper, paper towels, tissue paper, and the like.

[0046] The material of the sanitary thin paper 22 is not particularly limited, but may be, for example, a sheet of paper, nonwoven fabric, cloth, or the like, and is preferably paper (paper sheet). When the sanitary thin paper 22 is a paper sheet, a base paper containing pulp as the main raw material is used. The pulp composition may be a known composition for paper sheets. For example, the blending ratio of pulp may be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0047] The pulp composition of the sanitary thin paper 22 (paper sheet) is not particularly limited. For example, any ratio of softwood pulp such as NBKP (softwood kraft pulp) or NUKP (softwood unbleached pulp) to hardwood pulp such as LBKP (hardwood kraft pulp) or LUKP (hardwood unbleached pulp) can be used.

[0048] The ratio of hardwood pulp to softwood pulp is not limited, but is preferably 10:90 to 80:20, and more preferably, the ratio of softwood pulp to hardwood pulp is higher. The pulp contained in the sanitary thin paper 22 (paper sheet) may be recycled paper pulp.

[0049] The basis weight of the sanitary thin paper 22 is not particularly limited, but in the case of paper, it is 5 g / m depending on the number of plies. 2 More than 80g / m 2 less than 10 g / m 2 More than 60g / m 2 Less than 10 g / m 2 More than 45g / m 2 For nonwoven fabrics, the density is 20 g / m 2 More than 100g / m 2 The following is preferable. The basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0050] Furthermore, the thickness of the sanitary thin paper 22 (paper sheet) is not particularly limited, and may be a paper thickness measured under the environment of JIS P 8111 (1998). For example, when the sanitary thin paper 22 is paper, the paper thickness is 50 μm or more and 600 μm or less, preferably 60 μm or more and 500 μm or less, and more preferably 130 μm or more and 400 μm or less, per two plies.

[0051] The sanitary thin paper 22 (paper sheet) may be embossed. Such embossing can be performed by a known embossing method. The long sanitary thin paper 22 (paper sheet) may have perforations at predetermined intervals in the longitudinal direction for cutting.

[0052] There is no particular limit to the number of sanitary thin paper rolls 20 contained in the packaging bag 10. In the first embodiment, as shown in Figures 1 and 2, eight sanitary thin paper rolls 20 are contained in the packaging bag 10 so that two sanitary thin paper rolls 20 are stacked in two vertical rows of four. In a first modified example of the first embodiment, as shown in Figures 3 and 4, four sanitary thin paper rolls 20 are contained in the packaging bag 10 so that two sanitary thin paper rolls 20 are stacked in two vertical rows of two.

[0053] In addition, the upper end face of the upper sanitary thin paper roll 20 has two end faces in the width direction (Z direction) that face the top surface 11 of the packaging bag 10, and the lower end face faces the upper end surface of the lower sanitary thin paper roll 20, with part of the peripheral surface contacting part of the adjacent sanitary thin paper roll 20, and the other part of the peripheral surface facing part of the front 13, back 14, side 15, or side 16 of the packaging bag 10.

[0054] In addition, the upper end face of the lower sanitary thin paper roll 20 has two end faces in the width direction (Z direction) that face the lower end face of the upper sanitary thin paper roll 20, the lower end face faces the bottom surface 12 of the packaging bag 10, part of the peripheral surface contacts part of the adjacent sanitary thin paper roll 20, and the other part of the peripheral surface faces part of the front 13, back 14, side 15, or side 16 of the packaging bag 10.

[0055] As shown in Fig. 5, a plurality of sheet wrapping bodies 100 are housed in a case 200. This allows the sheet wrapping bodies 100 to be distributed in a state in which a plurality of sheet wrapping bodies 100 are housed in the case 200. Note that the case 200 in which a plurality of sheet wrapping bodies 100 are housed (hereinafter, sometimes referred to as a case body) shown in Fig. 5 is an example of a case body of the present disclosure.

[0056] The form of the case 200 is not particularly limited, and is, for example, a packaging box made of corrugated cardboard. The corrugated cardboard is formed by bonding a liner to one or both sides of a corrugated core. The corrugated cardboard is not particularly limited, and examples thereof include single-sided cardboard, double-sided cardboard, double-double-sided cardboard, and triple-double-sided cardboard. In this embodiment, type A corrugated cardboard is used as the corrugated cardboard.

[0057] The number of sheet wrapping bodies 100 accommodated in the case is not limited. In this embodiment, four sheet wrapping bodies 100 are accommodated in the case 200, but the number of sheet wrapping bodies 100 accommodated in the case may be two or more.

[0058] There is no particular limitation on the manner in which the sheet wrapping bodies 100 are housed in the case. In this embodiment, four sheet wrapping bodies 100 are arranged in one layer and housed in the case 200, but the sheet wrapping bodies 100 may be housed in two layers, with two sheets wrapped in one layer.

[0059] In this embodiment, as described above, since the sheet packaging body 100 can be distributed while being contained in the case 200, the sheet packaging body 100 is not provided with a handle. Specifically, a handle having a finger hook or the like is not provided on the top surface 11 of the packaging bag 10. Note that the above-mentioned seal portion 30 provided on the top surface 11 of the packaging bag 10 is a portion that closes the top surface 11 of the packaging bag 10, and does not constitute a handle.

[0060] In this embodiment, an air hole 40 is provided in the packaging bag 10 of the sheet packaging body 100. The number of air holes 40 provided in the packaging bag 10 is not particularly limited as long as it is one or more. The size of the air hole 40 is not particularly limited as long as it is a size that allows air to enter and exit. The shape of the air hole 40 is not particularly limited as long as it is a straight line, triangle, square, diamond, polygon with pentagons or more, circle, ellipse, star, etc. In this embodiment, a circular air hole 40 is provided.

[0061] As shown in Fig. 1, the air hole 40 is formed above half H2 of the height H1 of the sheet packaging body 100. In this embodiment, the air hole 40 is formed in the top surface 11 of the packaging bag 10, as shown in Figs. 1 and 2.

[0062] The position where the air hole 40 is formed is not limited to the top surface 11 of the packaging bag 10, but may be formed on the front surface 13, back surface 14, side surface 15, or side surface 16 of the packaging bag 10 as long as it is formed above half H2 of the height H1 of the sheet packaging body 100.

[0063] The air hole 40 may also be formed in the sealed portion 30. In a second modified example of the first embodiment, as shown in Fig. 6, non-sealed portions 31, 32 are formed in the sealed portion 30, and the non-sealed portions 31, 32 can communicate between the inside of the packaging bag 10 and the outside of the packaging bag 10 to form the air hole 40. The positions of the non-sealed portions 31, 32 formed in the sealed portion 30 are not limited, but are preferably positions corresponding to the boundary B between two adjacent sanitary thin paper products 20.

[0064] For example, when the sheet packaging body is the sheet packaging body 100 of the first embodiment (a sheet packaging body in which eight sanitary thin paper rolls 20 are contained in a packaging bag 10 so that four rolls are stacked on top of each other in two rows in the vertical direction), the position of the non-sealed portion 31 is preferably a position corresponding to the boundary B1 between the two sanitary thin paper rolls 20 on the side surface 15 and top surface 11 of the packaging bag 10 of the sheet packaging body 100. In addition, the position of the non-sealed portion 32 is preferably a position corresponding to the boundary B2 between the two sanitary thin paper rolls 20 on the side surface 16 and top surface 11 of the packaging bag 10 of the sheet packaging body 100.

[0065] The number of air holes 40 formed in the packaging bag 10 is not limited to one as shown in Fig. 1, and may be two or more. The two or more air holes 40 may be formed on the same surface of the packaging bag 10 (for example, only the top surface 11) or may be formed on different surfaces (for example, the top surface 11 and the front surface 13).

[0066] In this embodiment, as shown in Figure 2, the air hole 40 is formed at a position corresponding to the boundary B between two adjacent sanitary thin paper products 20. That is, when the sanitary thin paper products 20 are contained in the packaging bag 10, the air hole 40 is formed in a part of the packaging bag 10 that faces the boundary B between the two adjacent sanitary thin paper products 20. In this embodiment, the air hole 40 is formed at a position corresponding to the boundary B between the two sanitary thin paper rolls 20 on the top surface 11 side and front surface 13 side of the packaging bag 10.

[0067] In this embodiment, as shown in Figure 2, the air holes 40 are not formed in a position corresponding to the space 21A inside the hollow core (paper tube) 21 of the sanitary thin paper roll 20. In other words, when the sanitary thin paper product 20 is contained in the packaging bag 10, the air holes 40 are not formed in the part of the packaging bag 10 that faces the paper tube 21 and the space 21A surrounded by the paper tube 21.

[0068] Specifically, in the first embodiment, as shown in Figures 1 and 2, the air hole 40 is formed at a position corresponding to the boundary B between two adjacent sanitary thin paper rolls 20. In addition, in a first modified example of the first embodiment, as shown in Figures 3 and 4, the air hole 40 is formed at a position P corresponding to the upper end surface of the sanitary thin paper roll 20 excluding the space 21A surrounded by the paper tube 21.

[0069] In this embodiment, as described above, when a sheet packaging body 100 in which a plurality of sanitary thin paper products 20 are contained in a packaging bag 10 is contained in a plurality of units in a case 200 without being provided with a handle, an air hole 40 is provided in the packaging bag 10 and formed above half H2 of the height H1 of the sheet packaging body 100, thereby making it easier for air to escape from within the packaging bag 10. Therefore, in this embodiment, even when a handle is not provided and a plurality of units are packed in a box, the sheet packaging body 100 can be easily packaged, inserted into the case 200, and pulled out from the case 200.

[0070] In this embodiment, as described above, the air hole 40 is formed at a position corresponding to the boundary B between two adjacent sanitary thin paper products 20, which makes it easier for air that has accumulated to escape from the small space S1 formed between the two adjacent sanitary thin paper products 20 and the packaging bag 10. Therefore, in this embodiment, regardless of the shape or packaging manner of the sanitary thin paper products 20, even when no handles are provided and multiple units are packed in a box, the sheet packaging body 100 can be easily packaged, inserted into the case 200, and pulled out from the case 200.

[0071] In this embodiment, as described above, when a seal portion 30 that closes the packaging bag 10 is provided on the top surface 11 of the packaging bag 10, by forming an air hole 40 in such a seal portion 30, it is possible to prevent dust from entering the packaging bag 10 while making it easier for air to escape through the air hole 40.

[0072] In this embodiment, as described above, even if the sanitary thin paper product 20 is a sanitary thin paper roll, the air can be easily removed from the packaging bag 10, making it easier to wrap the sheet packaging body 100, insert it into the case 200, and pull it out from the case 200.

[0073] Furthermore, when the sanitary thin paper product 20 is a sanitary thin paper roll, the curved surface of the sanitary thin paper roll 20 forms a large space S2 in the area surrounded by two or more sanitary thin paper rolls 20 and the packaging bag 10, as shown in Figure 2. If air holes 40 are formed in a position corresponding to such space S2, the amount of air flowing in and out of the air holes 40 increases, making it easier for dust to enter the packaging bag 10 through the air holes 40.

[0074] In contrast, in the present embodiment, the air hole 40 is formed at a position corresponding to the boundary B between two adjacent sanitary thin paper rolls 20, thereby limiting the amount of air entering and exiting the air hole 40, thereby preventing dust from entering the packaging bag 10 through the air hole 40.

[0075] In this embodiment, as described above, when the sanitary thin paper product 20 is a sanitary thin paper roll, a space 21A is formed inside the paper tube 21 of the sanitary thin paper roll 20, and therefore, if air holes 40 are formed at a position corresponding to the space 21A of the paper tube 21, when a fragrance or deodorant is attached to the paper tube 21, the fragrance components or deodorant components tend to escape outside the packaging bag 10. In contrast, in this embodiment, the air holes 40 are not formed at a position corresponding to the space 21A inside the paper tube 21, and therefore, even when a fragrance or deodorant is attached to the paper tube 21, the fragrance components or deodorant components can be prevented from escaping outside the packaging bag 10.

[0076] In addition, as described above, in the case body of this embodiment, by forming a case body in which a plurality of sheet wrapping bodies 100 are housed in the case 200, the sheet wrapping bodies 100 housed in the case 200 have air holes 40 in the packaging bag 10, and the air holes 40 are formed above half H2 of the height H1 of the sheet wrapping body 100, so that air can easily escape from the packaging bag 10. Therefore, according to the case body of this embodiment, even if the sheet wrapping body 100 housed in the case 200 does not have a handle, it is easy to insert it into the case 200 and pull it out from the case 200.

[0077] <Second embodiment> Fig. 7 is a diagram showing a second embodiment of the sheet wrapping body. Fig. 8 is a diagram showing a modified example of the second embodiment of the sheet wrapping body. In Fig. 7 and Fig. 8, parts common to the first embodiment are denoted by the same or corresponding reference numerals as those in Fig. 1, and description thereof will be omitted.

[0078] In the sheet packaging body 100 of the second embodiment, the sanitary thin paper product 20 is an individual package, as shown in Fig. 7 and Fig. 8. The individual package 20 is a sanitary thin paper laminate in which sanitary thin papers are stacked, which is contained in an individual packaging bag. In the sheet packaging body 100 according to the second embodiment, such an individual package 20 is contained in a packaging bag 10.

[0079] A sanitary thin paper laminate is a laminate of multiple sheets (or multiple sets) of sanitary thin paper. The uses of the sanitary thin paper that constitutes the sanitary thin paper laminate are not particularly limited, and examples of such uses include tissue paper, paper towels, kitchen paper, toilet paper, and other sheets. Note that sanitary thin paper such as tissue paper and paper towels also includes sheets that contain a moisturizing component (or moisturizing agent) (for example, lotion tissue, etc.).

[0080] The material of the sanitary thin paper sheet is not particularly limited, and may be, for example, paper, nonwoven fabric, or cloth, and is preferably thin paper. When the sheet is thin paper, the pulp composition may be a known composition for thin paper. The blending ratio of pulp may be, for example, 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0081] The basis weight of the sheet is not particularly limited, but in the case of paper, it is 5 g / m depending on the number of plies. 2 More than 80g / m 2 less than 8 g / m 2 More than 50g / m 2 Less than 10 g / m 2 More than 20g / m 2 For nonwoven fabrics, the maximum is 20 g / m 2 More than 100g / m 2 The following is preferable. The basis weight is measured in accordance with the provisions of JIS P 8124 (2011).

[0082] The thickness of the sheet is not particularly limited, and the paper thickness measured under the environment of JIS P 8111 (1998) can be used. For example, when the sheet is a thin paper, the thickness of the thin paper is 40 μm or more and 500 μm or less per ply (two plies in the case of two plies), preferably 50 μm or more and 400 μm or less, more preferably 60 μm or more and 300 μm or less.

[0083] From the viewpoint of pulling out the sheets of the sanitary thin paper product one by one or one set at a time, the sanitary thin paper laminate is preferably one in which the sheets are folded and stacked alternately (a so-called pop-up type sanitary thin paper laminate). Furthermore, the form of the sanitary thin paper laminate is not limited to one that can be pulled out in a pop-up type, and it may be one in which multiple sheets (or multiple sets) are simply stacked, or one in which each sheet is stacked in a folded state.

[0084] In addition, the dimensions of the sanitary thin paper laminate can be such that the length in the longitudinal direction (X direction) of the sheet packaging body 100 is 155 mm or more and 230 mm or less, the length in the transverse direction or depth direction (Y direction) perpendicular to the longitudinal direction (X direction) of the sheet packaging body 100 is 80 mm or more and 120 mm or less, and the thickness in the height direction or thickness direction (Z direction) is 30 mm or more and 100 mm or less.

[0085] The individual packaging bag, when the sanitary thin paper laminate is contained therein, is a rectangular parallelepiped having a top surface, a bottom surface, a front surface, a back surface, and a pair of side surfaces. In the individual packaging bag, the top surface and the bottom surface face each other, the front surface and the back surface face each other, and a pair of side surfaces face each other. The side surfaces are continuous with all of the top surface, the bottom surface, the front surface, and the back surface.

[0086] The sanitary thin paper laminate contained in the individual packaging bag has a top surface, a bottom surface, and a pair of long sides that face the top surface, bottom surface, front surface, and back surface of the individual packaging bag, respectively, and a pair of short sides that face a pair of side surfaces.

[0087] The top surface of the individual packaging bag is provided with an outlet (not shown). The outlet is designed to allow the sheet of sanitary tissue paper to be pulled out. The outlet is configured as an opening. The opening constituting the outlet may be configured by tearing a perforation (intermittent cut).

[0088] The individual packaging bag is made of a resin film. The resin film constituting the individual packaging bag is flexible. The resin used for the resin film is not particularly limited, and for example, polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), polyamide (PA), etc. can be used. As the polyethylene, high density polyethylene, low density polyethylene, etc. can be used.

[0089] Among these, polyethylene, polypropylene, polyethylene terephthalate, etc. are preferred because they are flexible, easy to handle, have high sealability when heat sealed, and are inexpensive. Polyethylene is also preferred because it is odorless, has excellent water resistance and chemical resistance, and can be mass-produced at low cost. Polypropylene is also preferred because it is robust, easy to mold, has good color development when printed, and can be given a glossy finish.

[0090] The form of the resin film forming the individual packaging bags is not particularly limited, and may be a monolayer film formed of a single layer of the above-mentioned resin, a laminate film in which the above-mentioned resin is laminated, a film in which the above-mentioned resin is bonded or laminated with pulp paper or nonwoven fabric, or a mixed film formed from a mixture of two or more of the above-mentioned resins.

[0091] The thickness of the resin film forming the individual packaging bag is not particularly limited, and is preferably 10 μm or more and 100 μm or less, more preferably 15 μm or more and 70 μm or less. By making the thickness of the resin film 20 μm or more, sufficient strength as an individual packaging bag in which a sheet is contained can be ensured. In addition, by making the thickness of the resin film 100 μm or less, flexibility and light weight of the individual packaging bag can be ensured, and costs can be reduced.

[0092] The material used to form the individual packaging bags is not limited to resin film, but can also be paper, biodegradable materials (biodegradable plastics such as polylactic acid), and biomass materials (renewable organic resources derived from living organisms, such as biomass film, excluding fossil resources).

[0093] The packaging form of the individual packaging bag is not particularly limited. In this embodiment, for example, packaging in which both ends of a cylindrical resin film are folded and sealed (caramel packaging), packaging in which both ends or either one end of a cylindrical resin film folded in a gusset shape are sealed (pillow packaging), packaging in which a heat-shrinkable resin film is heated and adhered to the packaged object (shrink packaging), or a combination of these may be used. Among these, caramel packaging is preferred because it is easy to control the compaction of the sanitary tissue paper laminate.

[0094] In caramel packaging, the sanitary thin paper laminate is wrapped in a resin film by rolling it into a cylinder with both ends in the longitudinal direction (X direction) open, and the overlapping parts in the rolling direction are bonded by fusion processing or adhesive. Next, both ends in the longitudinal direction (X direction) of the cylindrical resin film are folded toward the end face side of the sanitary thin paper laminate, and at least the leading edge portions of the approximately triangular or approximately trapezoidal pieces formed in this process are overlapped and bonded by fusion processing or adhesive to seal the opening of the cylinder. In this embodiment, both ends (sides of the individual packaging bag) of the cylindrical resin film are folded and sealed.

[0095] In the second embodiment and the modified example of the second embodiment, the number and arrangement of the individual packages 20 contained in the packaging bag 10 are not particularly limited.

[0096] In the second embodiment, as shown in FIG. 7 , the bottom surfaces of the individual packaging bags of five individual packaging bodies 20 overlap with the top surfaces of the individual packaging bags of another individual packaging body 20, and the top surface of the individual packaging bag of the individual packaging body 20 located at one end faces the side surface 15 of the packaging bag 10 of the sheet packaging body 100, and the bottom surface of the individual packaging bag of the individual packaging body 20 located at the other end faces the side surface 16 of the packaging bag 10 of the sheet packaging body 100.

[0097] Furthermore, in a modified example of the second embodiment, as shown in Figures 9 and 10, the bottom surfaces of the individual packaging bags of five individual packaging bodies 20 overlap with the top surface of the individual packaging bag of another individual packaging body 20, and the top surface of the individual packaging bag of the individual packaging body 20 located at one end faces the top surface 11 of the packaging bag 10 of the sheet packaging body 100, and the bottom surface of the individual packaging bag of the individual packaging body 20 located at the other end faces the bottom surface 12 of the packaging bag 10 of the sheet packaging body 100.

[0098] In the second embodiment and the modified example of the second embodiment, as shown in Figures 7 to 10, the air hole 40 is formed above half H2 of the height H1 of the sheet packaging body 100. Specifically, in the second embodiment, as shown in Figures 7 and 8, the air hole 40 is formed on the top surface 11 of the packaging bag 10. In addition, in the modified example of the second embodiment, the air hole 40 is formed on the side surface 16 of the packaging bag 10.

[0099] The position where the air hole 40 is formed is not limited to the top surface 11 or side surface 16 of the packaging bag 10. In other words, even if the sanitary thin paper product 20 is an individually wrapped sanitary thin paper laminate, the air hole 40 may be formed on the front surface 13, back surface 14, or side surface 15 of the packaging bag 10, as long as it is formed above half H2 of the height H1 of the sheet packaging body 100.

[0100] In the second embodiment and the modified example of the second embodiment, the air hole 40 is formed at a position corresponding to the boundary B between two adjacent sanitary thin paper products 20. In other words, when the sanitary thin paper products 20 are contained in the packaging bag 10, the air hole 40 is formed in a part of the packaging bag 10 facing the boundary B between the two adjacent sanitary thin paper products 20.

[0101] In the second embodiment, an air hole 40 is formed on the front 13 side of the top surface 11 of the packaging bag 10, at a position corresponding to the boundary B between the individual packaging body 20 located at the other end (the individual packaging body 20 on the side 16 side of the packaging bag 10 of the sheet packaging body 100) and the individual packaging body 20 adjacent to it in the width direction (X direction).

[0102] In addition, in a modified example of the second embodiment, the air hole 40 is formed on the top surface 11 side of the front surface 13 and side surface 16 of the packaging bag 10, at a position corresponding to the boundary B between the individual packaging body 20 located at one end (the individual packaging body 20 on the top surface 11 side of the packaging bag 10 of the sheet packaging body 100) and the adjacent individual packaging body 20 in the height direction (Z direction).

[0103] In the second embodiment and the modified example of the second embodiment, as described above, when a sheet packaging body 100 in which a plurality of individual packages 20 are housed in a packaging bag 10 is not provided with a handle and a plurality of the sheets are housed in a case 200, air can be easily released from the packaging bag 10 by providing an air hole 40 in the packaging bag 10 and forming the air hole 40 above half H2 of the height H1 of the sheet packaging body 100. Therefore, in this embodiment, in a sheet packaging body 100 in which a handle is not provided and a plurality of the sheets are boxed, even if the sanitary thin paper products 20 are individual packages in which a sanitary thin paper laminate is housed in an individual packaging bag, packaging, insertion into the case 200, and removal from the case 200 are facilitated.

[0104] In the second embodiment and the modified example of the second embodiment, as described above, the air hole 40 is formed at a position corresponding to the boundary B between two adjacent individual packaging bodies 20, which makes it easier for air accumulated in the small space S1 formed between the two adjacent individual packaging bodies 20 and the packaging bag 10 to escape. Therefore, in the second embodiment and the modified example of the second embodiment, regardless of the shape and packaging manner of the individual packaging bodies 20, even in the case of a sheet packaging body 100 in which no handle is provided and a plurality of individual packaging bodies are packed in a box, the individual packaging bodies 20 can be easily packaged, inserted into the case 200, and pulled out from the case 200.

[0105] Furthermore, in the modified example of the second embodiment, as described above, the air hole 40 is formed on the side surface 16 of the packaging bag 10 of the sheet packaging body 100, making it more difficult for dust to enter the packaging bag 10 than when the air hole 40 is formed on the top surface 11 of the packaging bag 10 of the sheet packaging body 100.

[0106] Although an embodiment of the present invention has been described above, the present invention is not limited to a specific embodiment, and various modifications and changes are possible within the scope of the invention described in the claims. [Explanation of symbols]
