Description

[Technical Field]

[0001] This invention relates to a packaging box. [Background technology]

[0002] Sanitary tissue paper such as toilet paper is distributed in a form where multiple sheet rolls are contained in a plastic film packaging bag (for example, Patent Document 1). Furthermore, these sheet packages containing rolls of sanitary tissue paper are further packed into multiple corrugated cases for delivery, and after delivery, they are removed from the corrugated cases and displayed in stores in their film packaging form. In recent years, there has been growing interest in not using plastic film packaging bags from the perspective of reducing CO2 emissions and eliminating plastic. [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2017-124868 [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] Conventional sheet packaging uses plastic packaging bags, making it impossible to reduce the amount of plastic used. Furthermore, placing sheet packaging in corrugated cases or similar containers constitutes excessive packaging.

[0005] The objective of this invention is to package an object without using a plastic packaging bag. [Means for solving the problem]

[0006] A first aspect of the present invention is a corrugated cardboard packaging box for accommodating a plurality of packaged items, comprising: a rectangular top surface; a pair of long sides facing each other in the front-to-back direction of the packaging box; a pair of short sides facing each other in the left-to-right direction of the packaging box; the top surface comprising: a pair of inner flaps arranged at a predetermined distance apart in the left-to-right direction; a pair of outer flaps overlapping the pair of inner flaps and abutting together at the center in the front-to-back direction to close the top surface; an opening in which a part of the packaging box is opened; and a lid formed from a part of the packaging box corresponding to the opening, which connects the opening to the packaging box so as to be openable and closable; at least one of the pair of outer flaps being fixed to the pair of inner flaps; and the lid being formed without the inner flaps being cut out.

[0007] In the first embodiment, at least one of a pair of outer flaps is fixed to a pair of inner flaps, and the lid is formed without the inner flaps being cut out, so that an opening can be formed with little force without opening the entire top surface. Therefore, according to the first embodiment, an easy-to-open packaging box can be provided.

[0008] Furthermore, in the first embodiment, since at least one of the pair of outer flaps is fixed to the pair of inner flaps, the other flap that is not fixed to the pair of inner flaps can form a lid. This makes it possible to form a lid without cutting out a part of the packaging box, thus facilitating the formation of the lid.

[0009] Furthermore, in the first embodiment, since multiple items to be packaged are housed in a cardboard packaging box, the items to be packaged can be packaged without using plastic film packaging bags, thus contributing to plastic reduction while suppressing excessive packaging.

[0010] A second aspect of the present invention is a packaging box in which a tearing line is formed on the tip of the outer flap, which is fixed to the pair of inner flaps, in a portion that does not overlap with the inner flaps.

[0011] In the second embodiment, a tearing cut line is formed at the tip of one outer flap fixed to a pair of inner flaps, thereby forming a finger-grip notch at the tip of the other outer flap. This allows the other outer flap to be peeled away from the pair of inner flaps by placing a finger on it.

[0012] With this configuration, in the second embodiment, it is easy to configure the other outer flap as a lid. Furthermore, in the second embodiment, by configuring the other outer flap as a lid, a compact opening can be formed that is enclosed by the tip of one outer flap on the top surface, the tips of the pair of inner flaps, and the long side of the top surface.

[0013] A third aspect of the present invention is a packaging box in which the pair of outer flaps are fixed to the pair of inner flaps, the lid is composed of a portion of one of the pair of outer flaps closer to the one long side and a portion of the one long side closer to the one outer flap, and the lid is connected to the one outer flap.

[0014] In the third embodiment, a pair of outer flaps are fixed to a pair of inner flaps, and a portion of the lid is formed from the part of one of the outer flaps that is closer to one of its long sides, so that a portion of the opening that opens to the top surface is limited to the part of one of the outer flaps that is closer to one of its long sides. As a result, dust is less likely to enter through the opening after the packaging box is opened, and the packaged items are easier to store.

[0015] A fourth aspect of the present invention is a packaging box in which the pair of outer flaps are fixed to the pair of inner flaps, the lid is composed of the entire top surface, the portion of one of the pair of long sides closer to the top surface, and the portion of the pair of short sides closer to the top surface, and the lid is connected to the other long side of the pair of long sides.

[0016] In the fourth aspect, a pair of outer flaps are fixed to a pair of inner flaps, and the lid body is composed of the entire top surface and a portion near the top surface of one of the long side surfaces of the pair of long side surfaces and a portion near the top surface of the pair of short side surfaces. By doing so, an outlet having the same width as the top surface can be formed on the top surface side without opening the entire top surface. Therefore, even when the number of packaged objects in the packaging box decreases, it is easy to take out the packaged objects.

[0017] The fifth aspect of the present invention is a packaging box in which the packaged object is a roll-shaped sanitary tissue paper. In the fifth aspect, since the packaged object is a roll-shaped sanitary tissue paper, it is required to be hygienic during storage. However, as described above, since the packaging box is provided with a lid body, it is difficult for dust to enter from the outlet. Therefore, in the fifth aspect, even if the packaged object is a roll-shaped sanitary tissue paper, it can be stored hygienically.

Effects of the Invention

[0018] According to one aspect of the present invention, the packaged object can be packaged without using a resin-made packaging bag.

[Modes for carrying out the invention]

[0020] Embodiments of the present invention will be described in detail with reference to the drawings. In each drawing, common parts may be denoted by the same reference numerals and their descriptions may be omitted. Also, the scale of each component in each drawing may differ from the actual scale. In each drawing, a three-dimensional Cartesian coordinate system with three axes (X, Y, and Z directions) is used, with the longitudinal direction of the packaging box being the X direction, the width direction being the Y direction, and the height direction (vertical or thickness direction) being the Z direction.

[0021] Figure 1 is a top view of an example of a packaging box containing multiple packaged items. Figure 2 is a front view of the packaging box from Figure 1. Figure 3 is a diagram showing an example of packaged items contained in the packaging box. Figure 4 is a top view showing a first embodiment of the packaging box.

[0022] The packaging box 10 is a corrugated cardboard packaging box. The packaging box 10 is an example of a packaging box according to this embodiment. Corrugated cardboard is made by laminating a liner to one or both sides of a corrugated core. The corrugated cardboard is not particularly limited and examples include single-sided corrugated cardboard, double-sided corrugated cardboard, double-double-sided corrugated cardboard, and triple-double-sided corrugated cardboard. In this embodiment, A-type corrugated cardboard is used as the corrugated cardboard. That is, the packaging box 10 has a paper ratio of 100%.

[0023] Furthermore, the dimensions of the packaging box 10 are not particularly limited, but for example, the length of the packaging box 10 in the left-right direction (X direction) is 160 mm or more and 750 mm or less, the width of the packaging box 10 in the front-back direction (Y direction) is 85 mm or more and 375 mm or less, and the height in the up-down direction (Z direction) is 160 mm or more and 530 mm or less.

[0024] The packaging box 10 has a rectangular top surface 11, a bottom surface 12 facing the top surface 11 in the vertical direction (Z direction) of the packaging box, a pair of long sides 13 and 14 facing each other in the front-to-back direction (Y direction) of the packaging box 10, and a pair of short sides 15 and 16 facing each other in the left-to-right direction (X direction) of the packaging box 10. The long sides 13 and 14 are sides that extend from the long side LS of the top surface 11 to the long side LS of the bottom surface 12. The short sides 15 and 16 are sides that extend from the short side SS of the top surface 11 to the short side SS of the bottom surface 12.

[0025] The packaging box 10 has a top surface 11 which includes a pair of inner flaps and a pair of outer flaps 11C and 11D.

[0026] The inner flaps 11A and 11B are arranged with a predetermined interval S in the left-right direction (X direction). The predetermined interval S is 0.5 to 3 times the length L of the inner flaps 11A and 11B in the X direction, preferably 1 to 2.5 times, and more preferably 1.5 to 2 times.

[0027] The corners S1 at both ends of the tip T1 of the inner flap 11A may be notched. The corners S2 at both ends of the tip T2 of the inner flap 11B may also be notched (Figure 4). By noting the corners S1 and S2 at both ends of the tips T1 and T2 of the inner flaps 11A and 11B in this way, the corners S1 and S2 at both ends of the tips T1 and T2 of the inner flaps 11A and 11B do not come into contact with the pair of long sides 13 and 14, making it easier to assemble the packaging box 10.

[0028] The outer flaps 11C and 11D overlap the inner flaps 11A and 11B and abut at the center C1 in the front-to-back direction (Y direction) to close the top surface 11. That is, with the outer flaps 11C and 11D overlapping the inner flaps 11A and 11B, the tips T3 and T4 of the outer flaps 11C and 11D are positioned at the center C1 in the front-to-back direction (Y direction).

[0029] The packaging box 10 contains multiple items to be packaged 20. In this embodiment, rolls of sanitary tissue paper (for example, toilet paper) are stored as the items to be packaged 20. Rolls of sanitary tissue paper are an example of an item to be packaged in this embodiment.

[0030] In the examples shown in Figures 1 and 2, 24 rolls of toilet paper 20 are contained in the packaging box 10. In the examples shown in Figures 3 and 4, 12 rolls are contained in the packaging box 10. The following explanation will use the examples shown in Figures 1 and 2.

[0031] As shown in Figure 5, the toilet paper 20 is constructed by winding a long sheet 21 around a hollow core 22.

[0032] The sheet is not limited to a sheet roll as in this embodiment; it may also be a sheet laminate in which multiple sheets are stacked together.

[0033] The form of the sanitary tissue paper is not particularly limited and can be applied to, for example, toilet paper, kitchen paper, paper towels, tissue paper, etc. The use of the sanitary tissue paper is not particularly limited and can be applied to industrial, household, or portable use. Among these, household toilet paper is preferably used as the roll-shaped sanitary tissue paper in this embodiment.

[0034] The circumferential surface 21A of the toilet paper 20 faces the top surface 11, bottom surface 12, long side (front) 13, and long side (back) 14 of the packaging box 10, respectively, and a portion of the circumferential surface 21A is in contact with a portion of the circumferential surface 21A of an adjacent toilet paper 20. Of the four toilet paper 20s, the two on the short side (side) 15 side of the packaging box 10 have their sides 21B facing the short side (side) 15 of the packaging box 10, and the two on the short side (side) 16 side of the packaging box 10 have their sides 21C facing the short side (side) 16 of the packaging box 10.

[0035] The dimensions of the toilet paper 20 are not particularly limited, but the width dimension (roll width) W of the long sheet 21 is preferably 85 mm or more and 300 mm or less, the diameter dimension (roll diameter) D1 of the long sheet 21 is preferably 80 mm or more and 125 mm or less, and the winding density is 0.50 m / cm 2 More than 0.80m / cm 2 The following are long roll specifications with a length of 20m to 40m.

[0036] The number of plies in the long sheet 21 is not particularly limited, but can be one or more plies, preferably one ply or two plies (two layers).

[0037] The material of the long sheet 21 is not particularly limited, but for example, sheets of paper, nonwoven fabric, or cloth can be used, and paper (paper sheet) is preferred. When the long sheet 21 is a paper sheet, base paper with pulp as the main raw material is used. The pulp composition can be any known composition for paper sheets. For example, the pulp blending ratio can be 50% by mass or more, preferably 90% by mass or more, and more preferably 100% by mass.

[0038] Furthermore, the pulp composition in the long sheet 21 (paper sheet) is not particularly limited. For example, softwood pulp such as NBKP (coniferous kraft pulp) or NUKP (unbleached softwood pulp) and hardwood pulp such as LBKP (hardwood kraft pulp) or LUKP (unbleached hardwood pulp) can be used in any ratio.

[0039] The ratio of hardwood pulp to softwood pulp is not limited, but is preferably 10:90 to 80:20, and more preferably a pulp composition with a higher proportion of softwood pulp to hardwood pulp. In addition, recycled paper pulp may be used for the pulp contained in the long sheet 21 (paper sheet).

[0040] The basis weight of the long sheet 21 is not particularly limited, but depends on the number of plies, and in the case of paper, it is 5 g / m². 2 More than 80g / m 2 The following is preferable: 10 g / m²2 60 g / m² or less, more preferably 10 g / m² 2 or more and 45 g / m² 2 or less. In the case of a non-woven fabric, it is 20 g / m² 2 or more and 100 g / m² 2 or less. The basis weight is measured in accordance with the provisions of JIS P 8124 (2011). 2

[0041] Also, the thickness of the long sheet 21 (paper sheet) is not particularly limited, and the paper thickness measured under the environment of JIS P 8111 (1998) can be adopted. For example, when the long sheet 21 is paper, the paper thickness is 50 μm or more and 200 μm or less per ply, preferably 60 μm or more and 150 μm or less, and more preferably 80 μm or more and 100 μm or less.

[0042]

[0043]

[0044] Also, the hollow core 22 is a cylindrical core around which the long sheet 21 is wound in the circumferential direction (R direction) (see FIG. 2). The hollow core 22 also includes a structure without a core (coreless structure). The material of the hollow core 22 is not particularly limited, and paper, resin, etc. can be used.

[0045] The form of the hollow core 22 is not particularly limited. For example, when the hollow core 22 is a paper tube, it may be composed of a single layer of cardboard, a multi-layer of cardboard, or a coated cardboard base paper with printing or deodorant coating applied to the cardboard in advance. Also, the winding method of the paper tube is not particularly limited, and it may be, for example, a flat-wound one, a spirally wound one (so-called spiral paper tube), etc.

[0046] The dimensions of the hollow core 22 are not particularly limited. For example, the length of the hollow core 22 in the longitudinal direction is about the same as the width of the toilet paper roll 20 (85 mm to 300 mm). Also, the radial diameter D2 of the hollow core 22 is 33 mm to 50 mm, preferably 35 mm to 41 mm (see Figure 3).

[0046] The number of toilet paper rolls 20 that can be stored in the packaging box 10 is not limited, but for example, 4 to 32 rolls of toilet paper rolls 20 can be stored. In this embodiment, for example, 24 rolls of toilet paper rolls 20 are stored in the packaging box 10 such that their radial surfaces 21A overlap in the vertical and horizontal directions, and their side surfaces 21B and 21C overlap in the front-to-back direction (Figures 1 and 2).

[0047] The packaging box 10 has an opening OP. The opening OP is formed by opening a part of the packaging box 10. The opening OP is an opening that allows each packaged item (toilet paper) 20 contained in the packaging box 10 to be removed from the packaging box 10.

[0048] The packaging box 10 is provided with a lid 17. The lid 17 is formed from a part of the packaging box 10 that corresponds to the dispensing opening OP. The lid 17 connects to the packaging box 10 so that the dispensing opening OP can be opened and closed.

[0049] The lid 17 is formed without the inner flaps 11A and 11B being cut out. In this case, at least one of the pair of outer flaps 11C and 11D is fixed to the pair of inner flaps 11A and 11B. That is, either only one of the outer flaps 11C and 11D is fixed to the pair of inner flaps, or both of the outer flaps 11C and 11D are fixed.

[0050] Figure 6 shows a first embodiment of the packaging box. In the packaging box 10 of the first embodiment, the dispensing opening OP is formed on the top surface 11 as an opening OP surrounded by the tip T4 of the outer flap 11D, the tip T1 of the inner flap 11A, the tip T2 of the inner flap 11B, and the long side LS of the top surface 11.

[0051] In this case, at least one of the pair of outer flaps 11C and 11D (for example, outer flap 11D) is fixed to the pair of inner flaps 11A and 11B. The other outer flap 11C is not fixed to the pair of inner flaps 11A and 11B and constitutes the lid 17 (Figures 6 and 7).

[0052] In the packaging box 10 of this embodiment, a tear-off line is formed on the tip T4 of the outer flap 11D, which is fixed to a pair of inner flaps 11A and 11B, in a portion that does not overlap with the inner flaps 11A and 11B. Here, the tear-off line indicates a cut line in which cuts and ties (uncut portions between two cuts) are arranged alternately, and when a tie breaks, the cuts on both sides become a continuous cut.

[0053] For example, in the example shown in Figure 6 of this embodiment, a tear line 30 is formed on one of the outer flaps 11D at the center C2 in the left-right direction of the top surface 11, extending from the tip T4 of the outer flap 11D. The tear line 30 is composed of two perforations 31 and 32 that are opposite each other with a predetermined interval between them.

[0054] In this configuration, by tearing along the tearing lines 30 (perforations 31 and 32), a finger hole is formed at the tip T3 of the other outer flap 11C (Figure 7).

[0055] Furthermore, in the example shown in Figure 7 of this embodiment (a modified version of Figure 6), on one of the outer flaps 11D, tearing lines 40 and 50 are formed, respectively, extending from the tip T4 of the outer flap 11D, at the center C1 in the front-to-back direction of the top surface 11, closer to the inner flaps 11A and 11B. The tearing line 40 consists of two opposing perforations 41 and 42 spaced apart. The tearing line 50 consists of two opposing perforations 51 and 52 spaced apart.

[0056] In this configuration, by tearing along the tearing lines 40 (perforations 41, 42) and / or the tearing lines 50 (perforations 51, 52), two finger holes are formed at the tip T3 of the other outer flap 11C (Figure 7).

[0057] In this embodiment, as described above, at least one of the pair of outer flaps 11C and 11D (for example, outer flap 11D) is fixed to the pair of inner flaps 11A and 11B, and the lid 17 is formed without the inner flaps 11A and 11B being cut out. This allows the dispensing opening OP to be formed with little force without opening the entire top surface 11. Therefore, according to this embodiment, an easy-to-open packaging box 10 can be provided.

[0058] Furthermore, in this embodiment, as described above, at least one of the pair of outer flaps 11C and 11D (for example, outer flap 11D) is fixed to the pair of inner flaps 11A and 11B. As a result, the other outer flap 11C that is not fixed to the pair of inner flaps 11A and 11B can form a lid 17, and the lid 17 can be formed without cutting out a part of the packaging box 10, thus making the formation of the lid 17 easy.

[0059] Furthermore, in this embodiment, multiple packages (roll-shaped sanitary tissue paper) 20 are housed in a corrugated cardboard packaging box 10, allowing the packages 20 to be packaged without using a plastic film packaging bag. Therefore, the packaging box 10 of this embodiment can suppress excessive packaging while contributing to plastic reduction.

[0060] In this embodiment, as described above, by forming tearing cuts 30, 40, and 50 at the tip T4 of one outer flap 11D fixed to a pair of inner flaps 11A and 11B, a finger notch can be formed at the tip T3 of the other outer flap 11C. This allows the other outer flap 11C to be peeled away from the pair of inner flaps 11A and 11B by placing a finger on it.

[0061] With this configuration, in this embodiment, it is easy to configure the other outer flap 11C as a lid 17. In this embodiment, the other outer flap 11C is configured as a lid 17, and a compact outlet OP can be formed surrounded by the tip T4 of one outer flap 11D on the top surface 11, the respective tips T1 and T2 of the pair of inner flaps 11A and 11B, and the long side LS of the top surface 11.

[0062] Figure 8 shows a second embodiment of the packaging box. In the second embodiment, parts common to the first embodiment are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0063] In the packaging box 10 of the second embodiment, a pair of outer flaps 11C and 11D are fixed to a pair of inner flaps 11A and 11B. That is, both outer flaps 11C and 11D are fixed to a pair of inner flaps.

[0064] In the packaging box 10 of the second embodiment, the lid 17 is composed of a portion 17A of one of the pair of outer flaps 11C, 11D (outer flap 11C) near one of the long sides (front 13), and a portion 17B of one of the long sides (front) 13 near one of the outer flaps 11C. The lid 17 is further connected to the other outer flap 11C.

[0065] In the second embodiment, a channel-shaped tearing cut line 60 is provided on one long side (front) 13 portion 17A of the outer flap 11C) and on one long side (front) 13 portion 17B of the outer flap 11C. The ends 61 and 62 of the tearing cut line 60 are located on the outer flap 11C. The space between the ends 61 and 62 of the tearing cut line 60 constitutes the base end BS of the lid 17.

[0066] In the second embodiment, by splitting the splitting line 60, a lid 17 is formed, which consists of a portion 17A of the outer flap 11C) near one long side (front) 13 and a portion 17B of the outer flap 11C near one long side (front) 13. At this time, the space between the ends 61 and 62 of the splitting line 60 constitutes the base end BS of the lid 17. The lid 17 can be bent at the base end BS and rotated relative to the base end BS.

[0067] Furthermore, a crease (scribed line) may be formed in advance on the base end BS. Forming a crease on the base end BS facilitates the rotational movement of the lid 17.

[0068] In the second embodiment, a pair of outer flaps 11C and 11D are fixed to a pair of inner flaps, and a portion of the lid is formed from the part of one of the outer flaps (outer flap 11C) that is closer to one of the long sides (front) 13. As a result, a portion of the dispensing opening OP that opens to the top surface 11 is limited to the part of one of the outer flaps 11C that is closer to one of the long sides (front) 13. Therefore, dust is less likely to enter through the dispensing opening OP after the packaging box 10 is opened, and the packaged item (toilet paper) 20 is easier to store.

[0069] Figure 9 shows a third embodiment of the packaging box. In the third embodiment, parts common to the first embodiment are denoted by the same or corresponding reference numerals and their descriptions are omitted.

[0070] In the packaging box 10 of the third embodiment, a pair of outer flaps 11C and 11D are fixed to a pair of inner flaps 11A and 11B. That is, both outer flaps 11C and 11D are fixed to a pair of inner flaps.

[0071] In the third embodiment of the packaging box 10, the lid 17 is composed of the entire top surface 11, a portion 17A of one of the pair of long sides (front 13, back 14) near the top surface 11 on the long side (front) 13, and portions 17B and 17C of the pair of short sides (sides 15, 16) near the top surface 11. The lid 17 is connected to the other long side (back 14) of the pair of long sides (front 13, back 14).

[0072] In the third embodiment, a tearing line 70 is formed that extends from the other long side (edge ​​15A on the back surface 14 side of side 15) of one short side (side 15) through one long side (front surface 13) to the other long side (edge ​​16A on the back surface 14 side of side 16) of the other short side (side 16). The tearing line 70 is composed of two perforations 71 and 72 that are opposite each other with a predetermined interval between them.

[0073] In this configuration, by tearing along the tearing lines 70 (perforations 71, 72), a portion 10A of the packaging box 10 is cut out in a strip shape, and a linear notch is formed corresponding to the portion 10A of the packaging box 10 that has been cut out in a strip shape (Figure 9). This forms a lid 17 which consists of the entire top surface 11, a portion 17A of one of the long sides (front) 13 near the top surface 11, and portions 17B and 17C of a pair of short sides (sides 15, 16) near the top surface 11.

[0074] The perforations 71 of the tearing line 70 form the base end BS of the lid 17 formed on the back surface 14 between the end 71A of the side surface 15 on the back surface 14 side and the end 71B of the side surface 16 on the back surface 14 side. The lid 17 can be folded at the base end BS and rotated relative to the base end BS. A crease (score) may be formed in advance at the base end BS. Forming a crease at the base end BS facilitates the rotation of the lid 17.

[0075] In the third embodiment, a pair of outer flaps 11C and 11D are fixed to a pair of inner flaps 11A and 11B, and the lid 17 is composed of the entire top surface 11, a portion of one of the pair of long sides (front 13, back 14) closer to the top surface 11 on the long side (front 13), and a portion of the pair of short sides (sides 15 and 16) closer to the top surface 11.

[0076] This allows for the formation of an opening OP on the top surface 11 side that is the same size as the top surface 11, without having to open the entire top surface 11. Therefore, even when the amount of packaged material (toilet paper 20) inside the packaging box 10 decreases, it is easy to remove the packaged material (toilet paper 20).

[0077] Furthermore, the configuration of the third embodiment shown in Figure 9 may be combined with the configuration of the second embodiment shown in Figure 8. This allows the configuration of the second embodiment (Figure 8) to be used when there is a large amount of packaged material (toilet paper 20) in the packaging box 10, and the configuration of the third embodiment (Figure 9) to be used when there is a small amount of packaged material (toilet paper 20) in the packaging box 10.

[0078] In this embodiment, since the packaged material is roll-shaped sanitary tissue paper (toilet paper) 20, hygiene during storage is required. However, as described above, the packaging box 10 is provided with a lid 17, which prevents dust from entering through the dispensing opening OP. Therefore, in this embodiment, even though the packaged material is roll-shaped sanitary tissue paper (toilet paper) 20, it can be stored hygienically.

[0079] Although embodiments of the present invention have been described above, the present invention is not limited to any particular embodiment, and various modifications and changes are possible within the scope of the invention as described in the claims. [Explanation of symbols]
