Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the lid piece 110 of the box is configured to be bent at the horizontal bending portion 108 to cover the openings of the side plates 101, 102, 103, 104. However, when some force is applied to the box, the bent lid piece 110 may open the openings of the side plates 101, 102, 103, 104, and the box may unintentionally open and the contents may come out. In recent years, it has been required that such a box also consider the environment.

[0005] Therefore, the present invention aims to provide a box that can be easily opened while preventing it from opening unintentionally, and is also environmentally friendly. [Means for solving the problem]

[0006] The box of the present invention comprises: a first wall surface having a base edge, a tip edge extending parallel to the base edge, and a pair of side edges connecting the base edge and the tip edge, and which can be opened and closed by rotating around the base edge as an axis; a second wall surface having a first opposing side edge facing one of the pair of side edges, and a flap extending inward from the first opposing side edge; and a third wall surface having a second opposing side edge facing the other of the pair of side edges, and a flap extending inward from the second opposing side edge, wherein the inner surface of the edge on one side of the first wall surface and the outer surface of the flap of the second wall surface are connected by a one-sided adhesive portion, and the one-sided adhesive portion is positioned between the base edge and the tip edge, so as to be close to the base edge.

[0007] With this configuration, the first wall portion is bonded to the flap of the second wall portion by the adhesive portion on one side, preventing the box from opening unintentionally. Furthermore, since the adhesive portion on one side is positioned close to the base edge, compared to when the adhesive portion on one side is positioned close to the tip edge, the adhesive portion on one side is easier to detach and the box is easier to open when the tip edge is grasped and the first wall portion is rotated. In addition, by positioning the adhesive portion on one side close to the base edge, it is possible to partially position it between the base edge and the tip edge, making the adhesive portion on one side compact and environmentally friendly.

[0008] Furthermore, in the box, a slit may be formed on at least one surface of the inner surface of one side edge of the first wall surface where the one adhesive portion is provided, and on the outer surface of the flap of the second wall surface, so as to overlap with the one adhesive portion, or around the one adhesive portion.

[0009] With this configuration, the one-sided adhesive portion is prone to peeling due to the overlapping cuts and surrounding cuts in the adhesive portion.

[0010] Furthermore, in the box, the cut may be formed so as to surround the one adhesive portion.

[0011] With this configuration, the cut surrounding one adhesive area makes it easier to peel off that area, and allows only the area surrounded by the cut to be peeled off.

[0012] Furthermore, in the box, the first wall portion is provided with a dividing portion between the base edge and the tip edge, and the first wall portion may be separable from the dividing portion into the base edge side and the tip edge side.

[0013] With this configuration, the base edge can be peeled off and opened by dividing the first wall section.

[0014] Furthermore, the box may include a connecting wall portion that connects the base edge and the tip edge of the first wall portion, and the first wall portion and the connecting wall portion may form an annular wall that defines the storage space of the box, and the annular wall may unfold in a strip shape when the first wall portion is divided at the dividing portion.

[0015] With this configuration, after removing the contents from the box, the first wall section is divided at the dividing section, causing the annular wall to unfold in a strip shape, thus allowing the box to be laid flat. [Effects of the Invention]

[0016] Based on the above, the present invention provides a box that can be easily opened while preventing it from opening unintentionally, and is also environmentally friendly. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 4. The box 10 according to the present embodiment is, for example, a box made of cardboard used as a package for cosmetics, pharmaceuticals, foods, etc. Further, this box 10 has, for example, a substantially rectangular parallelepiped shape that can be developed in a plane. Note that the box 10 may be made of a resin plate material, a sheet, or the like.

[0019] As shown in FIG. 1, the box 10 has a base edge 11, a tip edge 12 extending parallel to the base edge 11, and a pair of side edges 13, 14 connecting the base edge 11 and the tip edge 12, and includes a first wall surface portion 1 that can be rotated about the base edge 11 to open and close. Further, as shown in FIG. 2 (developed view on the outer surface side), the box 10 has a second wall surface portion 2 having a first opposing side edge 210 facing one of the pair of side edges 13, 14 and a flap 22 extending inward (inward in the box 10) from the first opposing side edge 210, and a third wall surface portion 3 having a second opposing side edge 310 facing the other side edge 14 of the pair of side edges 13, 14 and a flap 32 extending inward (inward in the box 10) from the second opposing side edge 310.

[0020]

[0021] ​The second wall portion 2 has a bottom portion 21 that constitutes the bottom of the box 10. The second wall portion 2 also has a bottom connecting portion 211 that connects the bottom portion 21 and the annular wall 5, and bottom edge portions 212 and 213 that are edges facing the bottom portion of the annular wall 5. The first opposing side edge 210 connects the bottom portion 21 and the flap 22.

[0022] The bottom portion 21 is provided so as to be able to open and close relative to the annular wall 5 with the bottom connecting portion 211 as the fold line and the bottom connecting portion 211 as the axis. The flap 22 is folded with the first opposing side edge 210 as the fold line and the first opposing side edge 210 as the axis, and is overlapped on the inside of the first wall portion 1.

[0023] The third wall portion 3 has a top portion 31 that forms the top surface of the box 10. The third wall portion 3 also has a top connecting portion 311 that connects the top portion 31 and the annular wall 5, and top edge portions 312 and 313 that are edges facing the top portion of the annular wall 5. The second opposing side edge 310 connects the top portion 31 and the flap 32.

[0024] The top surface portion 31 is provided so as to be able to open and close relative to the annular wall 5 with the top surface connecting portion 311 as the fold line and the top surface connecting portion 311 as the axis. The flap 32 is folded with the second opposing side edge 310 as the fold line and the second opposing side edge 310 as the axis, and is overlapped on the inside of the first wall portion 1.

[0025] The first wall section 1 has a first main body section 15 that, together with the connecting wall section 4, constitutes the side surface of the box 10, and an adhesive allowance 16 that extends outward from the base edge 11. The adhesive allowance 16 is folded using the base edge 11 as a fold line and folded with the base edge 11 as the axis, so that it overlaps with the inside of the connecting wall section 4.

[0026] The inner surface of the edge 17 on one side edge 13 of the first wall section 1 and the outer surface of the flap 22 of the second wall section 2 are connected by a one-sided adhesive portion 60. The inner surface of the edge 18 on the other side edge 14 of the first wall section 1 and the outer surface of the flap 32 of the third wall section 3 are connected by a other-sided adhesive portion 61. In addition, the outer surface of the adhesive allowance 16 of the first wall section 1 and the inner surface of the connecting wall section 4 are connected by an annular wall adhesive portion 62.

[0027] Thus, in this embodiment, the first wall portion 1 and the second wall portion 2 are connected by one adhesive portion 60, and the first wall portion 1 and the third wall portion 3 are connected by the other adhesive portion 61. However, it is also possible to have a configuration in which the first wall portion 1 and the second wall portion 2 are bonded by one adhesive portion 60, and the first wall portion 1 and the third wall portion 3 are not connected (a configuration in which the other adhesive portion 61 is not provided). Furthermore, in this embodiment, one adhesive portion 60 and one other adhesive portion 61 are provided, but at least one of the adhesive portion 60 and the other adhesive portion 61 may be provided in multiple quantities.

[0028] One adhesive portion 60 is positioned between the base edge 11 and the tip edge 12, so as to be close to the base edge 11. In this embodiment, both the one adhesive portion 60 and the other adhesive portion 61 are positioned between the base edge 11 and the tip edge 12, so as to be close to the base edge 11.

[0029] Furthermore, in one adhesive portion 60, the center of the coating area (the center of the length from the base edge 11 to the tip edge 12) is located on the base edge 11 side of the center line between the base edge 11 and the tip edge 12. Also, in the one adhesive portion 60 of this embodiment, the entire coating area is located on the base edge 11 side of the center line between the base edge 11 and the tip edge 12. Similarly, the center of the coating area of ​​the other adhesive portion 61 (in this embodiment, the entire coating area of ​​the other adhesive portion 61) is located on the base edge 11 side of the center line between the base edge 11 and the tip edge 12. Note that if multiple one adhesive portions 60 and other adhesive portions 61 are provided, it is sufficient that the center of the coating area of ​​the adhesive portion 60, 61 closest to the base edge 11 is located on the base edge 11 side of the center line between the base edge 11 and the tip edge 12.

[0030] Furthermore, one adhesive portion 60 may be positioned between the base edge 11 and the tip edge 12, closer to the base edge 11. In this case, the other adhesive portion 61 may be positioned between the base edge 11 and the tip edge 12, closer to the tip edge 12, or it may be positioned in the center between the base edge 11 and the tip edge 12. Alternatively, the other adhesive portion 61 may be provided over the entire area from the base edge 11 to the tip edge 12.

[0031] In this embodiment, one adhesive portion 60 is formed by adhesive applied to the outer surface of the flap 22, the other adhesive portion 61 is formed by adhesive applied to the outer surface of the flap 32, and the annular wall adhesive portion 62 is formed by adhesive applied to the outer surface of the adhesive allowance 16. Alternatively, one adhesive portion 60 may be formed by adhesive applied to the inner surface of the edge portion 17 of the first wall portion 1, the other adhesive portion 61 may be formed by adhesive applied to the inner surface of the edge portion 18 of the first wall portion 1, and the annular wall adhesive portion 62 may be formed by adhesive applied to the inner surface of the connecting wall portion 4.

[0032] Each adhesive portion 60, 61, and 62 is formed from an adhesive such as polyester resin, acrylic resin, vinyl chloride resin, vinyl resin, polyamide resin, polyvinyl acetate resin, rubber resin, ethylene-vinyl acetate copolymer resin, or vinyl chloride acetate copolymer resin. Each adhesive portion 60, 61, and 62 may be a pressure-sensitive adhesive layer (adhesive layer) or a heat-sensitive adhesive layer (heat-seal layer).

[0033] On the one side, a half-cut 7 is formed on at least one surface of the first wall portion 1 on one side edge 13 side edge 17 and the second wall portion 2 flap 22, either overlapping with the one-sided adhesive portion 60 or around the one-sided adhesive portion 60. This half-cut 7 is positioned in the region where the one-sided adhesive portion 60 adheres to the inner surface of the edge 17 and the outer surface of the flap 22, and in this embodiment, it is provided on the outer surface of the flap 22. Furthermore, in the assembled box 10, the half-cut 7 is positioned between the base edge 11 and the tip edge 12, and is located close to the base edge 11. In this embodiment, the half-cut 7 is positioned between the base edge 11 and the tip edge 12 of the flap 22, and is located close to the base edge 11, in the assembled box 10. Furthermore, in this embodiment, the half-cut 7 is positioned between the first end edge 221 facing the base end edge 11 of the flap 22 and the second end edge 222 facing the tip end edge 12, so as to be close to the first end edge 221.

[0034] The half-cut 7 is formed by cutting into the edge 17 of the first wall portion 1 or the flap 22 of the second wall portion 2 in the thickness direction of the first wall portion 1 or the second wall portion 2. In this embodiment, the half-cut 7 is formed on the outer surface of the flap 22 of the second wall portion 2. The half-cut 7 may also be formed on the inner surface of the edge 17 of the first wall portion 1, or on both the inner surface of the edge 17 of the first wall portion 1 and the outer surface of the flap 22 of the second wall portion 2.

[0035] Furthermore, the half-cut 7 is formed on at least one surface of the other adhesive portion 61, either overlapping with the other adhesive portion 61 or around the other adhesive portion 61, on the inner surface of the edge portion 18 on the other side edge 14 side of the first wall portion 1 where the other adhesive portion 61 is provided, and on the outer surface of the flap 32 of the third wall portion 3. The half-cut 7 is positioned in the region where the other adhesive portion 61 adheres the inner surface of the edge portion 18 and the outer surface of the flap 32, and in this embodiment, it is provided on the outer surface of the flap 32. In addition, the half-cut 7 is positioned in the assembled box 10 between the base edge 11 and the tip edge 12, and is positioned close to the base edge 11. In this embodiment, the half-cut 7 is positioned in the assembled box 10 between the base edge 11 and the tip edge 12 of the flap 32, and is positioned close to the base edge 11. Furthermore, in this embodiment, the flap 32 is positioned between the first end edge 321 facing the base end edge 11 and the second end edge 322 facing the tip end edge 12, so as to be closer to the first end edge 321.

[0036] The half-cut 7 may be formed on the inner surface of the edge 18 of the first wall portion 1, or it may be formed on both the inner surface of the edge 18 of the first wall portion 1 and the outer surface of the flap 32 of the third wall portion 3.

[0037] The half-cut 7 is formed at a position spaced apart from the fold of the box 10 (in this embodiment, the first opposing side edge 210 and the second opposing side edge 310). In this way, since the half-cut 7 is located on the flat part of the box 10 after assembly, even if the half-cut 7 is pulled by the adhesive parts 60 and 61, the half-cut 7 is less likely to lift up, and defective products (for example, defective products that have been opened during transportation or display) are less likely to occur.

[0038] In this embodiment, the half-cut 7 has a first half-cut 71 as a first cut that surrounds the one adhesive portion 60. The first half-cut 71 is positioned closer to the bottom edge 213 than to the bottom edge 212. Specifically, the entire first half-cut 71 is positioned closer to the bottom edge 213 than the horizontal center line of the flap 22 of the second wall portion 2. Furthermore, the first half-cut 71 is positioned between the first edge 221 and the second edge 222 of the flap 22, so as to be closer to the first edge 221.

[0039] The first half-cut 71 has a pair of first portions 711 extending parallel to the base edge 11 and the tip edge 12, and a pair of second portions 712 extending perpendicular to the base edge 11 and the tip edge 12. The edges of the first portions 711 on the side furthest from the first opposing side edge 210 are connected by the second portions 712 located on the side furthest from the first opposing side edge 210. The first half-cut 71 also has a third portion 713 that connects the edge of the first portion 711 on the side closer to the first opposing side edge 210 with the edge of the second portion 712 located on the side closer to the first opposing side edge 210. The third portion 713 has a curved shape (R shape).

[0040] In addition, in the first half-cut 71, the edges of the first portion 711 on the side closer to the first opposing side edge 210 can be connected by the second portion 712 located on the side closer to the first opposing side edge 210. In this case, the first half-cut 71 will be rectangular in shape, formed only by the first portion 711 and the second portion 712. Alternatively, in the first half-cut 71, the edge of the first portion 711 on the side further from the first opposing side edge 210 and the second portion 712 located on the side further from the first opposing side edge 210 can be spaced apart and connected by a curved portion (third portion 713).

[0041] Furthermore, the half-cut 7 has a second half-cut 72, which is positioned inside the first half-cut 71 and is formed to overlap with the adhesive portion 60. The second half-cut 72 is a straight line extending parallel to the base edge 11 and the tip edge 12, and there are multiple (for example, six) of them. The multiple second half-cuts 72 are arranged at equal intervals from each other. In this embodiment, since the second half-cut 72 extends from one second portion 712 of the first half-cut 71 to the other second portion 712, the inner region of the first half-cut 71 is divided into multiple sections such that the base edge 11 and the tip edge 12 are aligned in opposing directions.

[0042] Furthermore, the half-cut 7 has a third half-cut 73, which is a third cut formed to surround the other adhesive portion 61. The third half-cut 73 is positioned closer to the top edge 313 than to the top edge 312. Specifically, the entire third half-cut 73 is positioned closer to the top edge 313 than the horizontal center line of the flap 32 of the third wall portion 3. Also, the third half-cut 73 is positioned closer to the first edge 321 between the first edge 321 and the second edge 322 of the flap 32.

[0043] The third half-cut 73 has a pair of first portions 731 extending parallel to the base edge 11 and the tip edge 12, and a pair of second portions 732 extending perpendicular to the base edge 11 and the tip edge 12. The edges of the first portions 731 on the side furthest from the second opposing side edge 310 are connected by the second portions 732 located on the side furthest from the second opposing side edge 310. The third half-cut 73 also has a third portion 733 that connects the edge of the first portion 731 on the side closer to the second opposing side edge 310 with the edge of the second portion 732 located on the side closer to the second opposing side edge 310. The third portion 733 has a curved shape (R shape).

[0044] In addition, in the third half-cut 73, the edges of the first portion 731 closer to the second opposing side edge 310 can be connected by the second portion 732 located closer to the second opposing side edge 310. In this case, the third half-cut 73 will be rectangular in shape, formed only by the first portion 731 and the second portion 732. Alternatively, in the third half-cut 73, the edge of the second portion 732 further from the second opposing side edge 310 and the second portion 732 located further from the second opposing side edge 310 may be spaced apart and connected by a curved portion (third portion 733).

[0045] Furthermore, the half-cut 7 has a fourth half-cut 74, which is positioned inside the third half-cut 73 and is formed to overlap with the other adhesive portion 61. The fourth half-cut 74 is a straight line extending parallel to the base edge 11 and the tip edge 12, and there are multiple (for example, six) of them. The multiple fourth half-cuts 74 are arranged at equal intervals from one another. In this embodiment, since the fourth half-cut 74 extends from one second portion 732 of the third half-cut 73 to the other second portion 732, the inner region of the third half-cut 73 is divided into multiple sections such that the base edge 11 and the tip edge 12 are aligned in opposing directions.

[0046] The second half-cut 72 and the fourth half-cut 74 may be just one. Furthermore, the second half-cut 72 and the fourth half-cut 74 may be straight lines parallel to the pair of side edges 13 and 14, or straight lines, curves, etc., extending in other directions.

[0047] In this embodiment, the first half-cut 71 and the third half-cut 73 are the same size and shape. Also, the second half-cut 72 and the fourth half-cut 74 are the same size and shape. However, the half-cuts 71 and 73 may be of different sizes or shapes, and the half-cuts 72 and 74 may be of different sizes or shapes.

[0048] Furthermore, in this embodiment, the first half-cut 71 and the third half-cut 73 do not penetrate the flaps 22 and 23 in the thickness direction. Similarly, the second half-cut 72 and the fourth half-cut 74 do not penetrate the flaps 22 and 23 in the thickness direction. However, the second half-cut 72 and the fourth half-cut 74 may be configured to partially penetrate the flaps 22 and 23 in the thickness direction.

[0049] When assembling the box 10, if the flap 22 is folded along the first opposing side edge 210, the paper tends to lift up in the area between the first opposing side edge 210 and the first half-cut 71. However, since the first half-cut 71 has an R-shape formed on the side closer to the first opposing side edge 210, the paper is less likely to lift up in the area between the first opposing side edge 210 and the first half-cut 71. As a result, the gap between the first wall portion 1 and the flap 22 is reduced, and the possibility of the box 10 being opened unintentionally is reduced. In addition, the ingress of dirt into the box 10 through the gap between the first wall portion 1 and the flap 22 is reduced, and the aesthetic appearance of the box 10 can be maintained. Furthermore, the third half-cut 73 also has a similar effect because it has an R-shape formed on the side closer to the second opposing side edge 310.

[0050] Furthermore, although multiple second half-cuts 72 and multiple fourth half-cuts 74 were arranged at equal intervals from each other, the spacing between adjacent second half-cuts 72 and adjacent fourth half-cuts 72 may be uneven. The number and spacing of the second half-cuts 72 and fourth half-cuts 74 should be set to ensure a balance between the strength of the box 10, which varies depending on the mass of the contents of the box 10 and the transport environment of the box 10, and the ease of opening the box 10.

[0051] The first wall portion 1 is provided with a dividing portion 19 between the base edge 11 and the tip edge 12. The first wall portion 1 can be divided into a base edge 11 side and a tip edge 12 side by the dividing portion 19. In this embodiment, when the first wall portion 1 is divided by the dividing portion 19, the annular wall 5 unfolds in a strip shape.

[0052] The dividing portion 19 is, for example, a perforation. This perforation penetrates the entire first wall portion 1 in the thickness direction. The dividing portion 19 is positioned between the base edge 11 and the tip edge 12, so as to be close to the tip edge 12. In other words, in the first wall portion 1, the base edge 11, the adhesive portion (in this embodiment, one adhesive portion 60 and the other adhesive portion 61), the dividing portion 19, and the tip edge 12 are arranged in that order.

[0053] Furthermore, the dividing portion 19 has a first dividing portion 191 that extends along the tip edge 12 at the center in the direction of alignment of the pair of side edges 13 and 14 (vertical direction in Figure 2). Furthermore, the dividing portion 19 has a second dividing portion 192 that extends from the corner formed by one side edge 13 and the tip edge 12 of the first wall portion 1 toward one end of the first dividing portion 191 (lower end in Figure 2), and a third dividing portion 193 that extends from the corner formed by the other side edge 14 and the tip edge 12 of the first main body portion 15 toward the other end of the first dividing portion 191 (upper end in Figure 2). The second dividing portion 192 and the third dividing portion 193 extend so that they move away from the tip edge 12 as they approach the center in the direction of alignment of the pair of side edges 13 and 14.

[0054] The dividing section 19 may be a straight line extending along the tip edge 12 between the pair of side edges 13 and 14. Furthermore, the dividing section 19 may have a configuration other than perforation, such as a half-cut.

[0055] The connecting wall section 4 has, for example, a fourth wall section 44, a fifth wall section 45, and a sixth wall section 46. In this way, the annular wall 5 is formed by the three-sided connecting wall section 4 and the first wall section 1, so the annular wall 5 is a rectangular tube shape with the first wall section 1, fourth wall section 44, fifth wall section 45, and sixth wall section 46 connected in the circumferential direction. The second wall section 2 and third wall section 3 are provided in the upper and lower openings of this annular wall 5, respectively, so that the box 10 is a hexahedron (specifically, a rectangular parallelepiped). Because the box 10 has this shape, multiple boxes 10 can be lined up without gaps, which is useful when transporting or displaying.

[0056] The connecting wall section 4 has a third opposing side edge 400 facing the base end edge 11 of the first wall section 1, a first connecting section 401 connecting the fourth wall section 44 and the fifth wall section 45, and a second connecting section 402 connecting the fifth wall section 45 and the sixth wall section 46. The connecting wall section 4 also has a third connecting section 403 facing the tip edge 12 of the first wall section 1. The connecting wall section 4 and the first wall section 1 are connected by the connection between the third connecting section 403 and the tip edge 12.

[0057] The fourth wall section 44 includes a fourth main body section 440 that constitutes the side surface of the box 10, and flaps 441 and 442 that extend outward from both ends of the fourth main body section 440 in the direction in which the pair of side edges 13 and 14 are aligned. The fourth wall section 44 also includes flap connecting sections 443 and 444 that connect the fourth main body section 440 and the flaps 441 and 442, respectively. The third opposing side edge 400 is superimposed on the base edge 11 by folding the fourth wall section 44 with the first connecting section 401 as the crease and the first connecting section 401 as the axis. The flap 441 is superimposed on the inside of the second wall section 2 by folding the flap connecting section 443 as the crease and the flap connecting section 443 as the axis. The flap 442 is folded using the flap connecting portion 444 as a crease and around the flap connecting portion 444 as an axis, thereby overlapping it with the inside of the third wall portion 3.

[0058] The fifth wall section 45 is composed of the fifth main body section 450, which forms the side of the box 10. The fifth wall section 45 is connected to the second wall section 2 (specifically, the bottom section 21) at the bottom and to the third wall section 3 (specifically, the top section 31) at the top.

[0059] The sixth wall section 46 includes a sixth main body section 460 that constitutes the side of the box 10, and flaps 461 and 462 that extend outward from both ends of the sixth main body section 460 in the direction in which the pair of side edges 13 and 14 are aligned. The sixth wall section 46 also includes flap connecting sections 463 and 464 that connect the sixth main body section 460 and the flaps 461 and 462, respectively. Flap 461 is folded using the flap connecting section 463 as a crease and around the flap connecting section 463 as an axis, thereby overlapping it on the inside of the second wall section 2. Flap 462 is folded using the flap connecting section 464 as a crease and around the flap connecting section 464 as an axis, thereby overlapping it on the inside of the third wall section 3.

[0060] The outer surface of the box 10 in this embodiment is provided with a display area that shows information such as instructions on how to use and handle the contents contained in the box 10. The display area may also be provided on the inner surface of the box 10. Furthermore, the display area only needs to be provided on at least one of the first wall section 1, second wall section 2, third wall section 3, fourth wall section 44, fifth wall section 45, and sixth wall section 46 of the box 10, and in this embodiment, it is provided on the outer surface of the first wall section 1 and the outer surface of the connecting wall section 4. Also, the display area only needs to be provided on at least one surface (at least one inner and outer surface) of the first wall section 1, second wall section 2, third wall section 3, fourth wall section 44, fifth wall section 45, and sixth wall section 46 of the box 10. In this way, since the display area is provided on the box 10 itself, there is no need to create a separate paper instruction manual, making it environmentally friendly.

[0061] With the box 10 described above, the first wall portion 1 is bonded to the flaps 22 and 32 of the second and third wall portions 2 and 3 by the one adhesive portion 60 and the other adhesive portion 61, thereby preventing the box from opening unintentionally. Furthermore, since the one adhesive portion 60 is positioned close to the base edge 11, compared to the case where the one adhesive portion 60 is positioned close to the tip edge 12, as shown in Figure 3, when the tip edge 12 side is grasped and the first wall portion 1 is rotated, the one adhesive portion 60 is more easily detached and the box 10 is easier to open. In addition, by positioning the one adhesive portion 60 close to the base edge 11, it is possible to partially position it between the base edge 11 and the tip edge 12, making the one adhesive portion 60 more compact and reducing the amount of adhesive used, which is environmentally friendly.

[0062] In the box 10 of this embodiment, the half-cut 71 overlapping the one adhesive portion 60 makes it easier to peel off the one adhesive portion 60. Similarly, the half-cut 72 overlapping the other adhesive portion 61 makes it easier to peel off the other adhesive portion 61. In this way, the half-cuts 71 and 72 make it easier to peel off the adhesive portions 60 and 61, so the box 10 can be opened even more easily.

[0063] Furthermore, in the box 10 of this embodiment, the first half-cut 71 surrounding the one adhesive portion 60 makes it easy to peel off the one adhesive portion 60, and allows only the area surrounded by the first half-cut 71 to be peeled off. In addition, the third half-cut 73 surrounding the other adhesive portion 61 makes it easy to peel off the other adhesive portion 61, and allows only the area surrounded by the third half-cut 73 to be peeled off.

[0064] The half-cuts 71-74 are easier to peel off from the surface of other parts of the box 10, and therefore serve as guides when peeling off the adhesive part 60 on one side and the adhesive part 61 on the other side. In addition, since the half-cuts 71-74 are provided on the outer surface of the box 10, in configurations where the display part is provided on the inner surface of the box 10, even if the surface of the box 10 is torn at the half-cuts 71-74, the display part will not be damaged.

[0065] Furthermore, in the box 10 of this embodiment, the first wall portion 1 can be separated at the dividing portion 19 provided between the base edge 11 and the tip edge 12, allowing the base edge 11 side to be peeled off and opened. In addition, in this box 10, the dividing portion 19 is a perforation, and the dividing portion 19 is visible from the appearance of the box 10, so consumers can immediately understand how the first wall portion 1 is separated by looking at the box 10.

[0066] In this box 10, the first wall portion 1 is divided into a tip end and a base end by dividing the dividing portion 19. At this time, the wall portion (first wall portion 1) held by the left hand in Figure 3 opens at the base end of the box 10, and the wall portion (fourth wall portion 44) held by the right hand in Figure 3 opens at the tip end of the box 10.

[0067] In the box 10 of this embodiment, as shown in Figure 4 (unfolded view of the inner surface), the annular wall 5 unfolds into a strip shape by dividing the first wall surface 1 at the dividing section 19, so that the box 10 can be flattened after the contents have been removed from the box 10. In this embodiment, because the annular wall 5 unfolds into a strip shape, the information displayed on the display section of the annular wall 5 is easy to read. In addition, instead of a description of the contents, the box 10 with the description can be stored in a compact state (unfolded on a flat surface). Furthermore, in this embodiment, no paper scraps are generated when the annular wall 5 is unfolded. Also, when disposing of the box 10, the volume of waste can be reduced, making it environmentally friendly.

[0068] Furthermore, the dividing section 19 has a shape in which both ends (second and third dividing sections 192 and 193) in the direction of alignment of the pair of side edges 13 and 14 of the dividing section 19 extend away from the tip edge 12 as they approach the center, that is, the width dimension in the vertical direction becomes narrower towards the base edge 11. In the dividing section 19 with this shape, the area in which the dividing section 19 is formed is longer compared to the shape in which the entire dividing section extends from the pair of side edges 13 and 14 along the tip edge 12. Also, because the dividing section 19 has a shape in which the width dimension in the vertical direction becomes narrower towards the base edge 11, as shown in Figure 3, when a consumer places their fingers on the tip edge 12 side of the first wall section 1 and pushes the tip edge 12 side of the first wall section 1 inward (inward into the box 10), it becomes easier to avoid the flaps 22 and 32 and to push it in. Furthermore, if the width of the lateral division portion 19 is wide (for example, about the width of a thumb), it becomes easier to press down on the tip edge 12 side of the first wall portion 1 with a thumb.

[0069] Furthermore, since the central part (first dividing section 191) in the direction of alignment of the pair of side edges 13 and 14 of the dividing section 19 is separated from the tip edge 12, a large area is secured between the first dividing section 191 and the tip edge 12, allowing consumers to apply their fingers (for example, their thumbs) in a stable position. This makes it easy to tear the dividing section 19.

[0070] Furthermore, as shown in Figure 3, the box 10 opens to the side, making it easy to remove the contents stored inside, and preventing the contents from falling out of the box when they are removed.

[0071] Furthermore, in this box 10, the one adhesive portion 60 and the other adhesive portion 61 are positioned closer to the base edge 11 than the center between the base edge 11 and the tip edge 12. As a result, the adhesive portions 60 and 61 overlap with the half-cut 7, which is easier to peel off than other parts formed on the outer surface of the second wall portion 2 and the third wall portion 3. Therefore, when opening the box 10, the surface of the half-cut 7 formed on the outer surface of the box 10 (for example, paper) peels off while adhering to the adhesive portions 60 and 61, allowing the box 10 to be opened without tearing the inner surface. This makes the markings on the inside of the opened box 10 easy to read. However, if the one adhesive portion 60 and the other adhesive portion 61 were positioned closer to the tip edge 12 than the center between the base edge 11 and the tip edge 12, they would not overlap with the half-cut 7. In this case, the inner surface of the first wall portion 1 would peel off while adhering to the adhesive portions 60 and 61, potentially tearing the inner surface of the box 10 and making the markings on the inside of the box 10 unreadable.

[0072] It should be noted that the box of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of one embodiment can be deleted.

[0073] For example, the half-cut 7 may be formed only in a position that overlaps with one adhesive portion 60, or only around the one adhesive portion 60. In this case, the half-cut 7 may not be formed in a position that overlaps with the other adhesive portion 61, or around the other adhesive portion 61. Alternatively, perforations may be formed as a cut instead of a half-cut. Note that the box 10 may not have a half-cut at all.

[0074] Furthermore, as shown in Figure 5 (unfolded view of the outer surface), the half-cut 7 may specifically extend to the central area in the horizontal direction of the flap 22 of the second wall section 2, or to the central area in the horizontal direction of the flap 32 of the third wall section 3. In this box 10 as well, the center of the first half-cut 71 is positioned closer to the bottom edge 213 than the horizontal center line of the flap 22 of the second wall section 2. The third half-cut 73 is positioned similarly. In this case, the area enclosed by the half-cut 7 becomes larger in which the adhesive portion 60 on one side and the adhesive portion 61 on the other side are not located, thereby increasing the tear strength of the area enclosed by the half-cut 7, and thus allowing the box 10 to accommodate heavy objects.

[0075] The connecting wall section 4 may be composed of a single wall section. In this case, the connecting wall section 4 will become curved after assembly. Alternatively, the connecting wall section 4 may be composed of four or more wall sections.

[0076] In the embodiments described above, the top surface 31 of the third wall portion 3 constituted the top surface of the box 10, but any surface of the box 10 other than the third wall portion 3 may constitute the top surface. For example, the first main body portion of the first wall portion 1 may constitute the top surface of the box 10. [Explanation of Symbols]
