[0009] [Figure 1] 1 is a perspective view showing a configuration example of a packaging box according to an embodiment. FIG. [Figure 2] 2 is a front view showing a configuration example of the unfolded body of the packaging box of FIG. 1. FIG. [Figure 3] 2 is a perspective view showing a process of changing the packaging box of FIG. 1 from a folded state to a usable state. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments will be described with reference to the drawings. Note that the present invention is not limited to the following embodiments. In addition, the same or corresponding elements will be denoted by the same reference numerals throughout the drawings, and redundant description will be omitted.

[0011] Fig. 1 is a perspective view showing an example of the configuration of a packaging box 100 according to an embodiment. As shown in Fig. 1, the packaging box 100 is a box formed by folding a single blank sheet, and is a box with a lid that has an item storage section whose internal space is divided by a partition. The packaging box 100 is made of, for example, cardboard, and has an item storage section including a first storage section 1 and a second storage section 2, a connecting section 3, and a lid body 5.

[0012] The first storage section 1 includes a first bottom wall 11 and a first peripheral wall 12. The first bottom wall 11 is a rectangular plate-like body having a pair of side edges extending in the front-to-rear direction, a front edge connecting one end of the pair of side edges, and a rear edge connecting the other end of the pair of side edges. Hereinafter, when the lid of the packaging box 100 is closed, the side on which the front edge of the first bottom wall 11 is located may simply be referred to as the front, and the side on which the rear edge is located may simply be referred to as the rear. Furthermore, the left and right sides of the packaging box 100 when the front edge of the first bottom wall 11 is positioned in the foreground may simply be referred to as the left and right, respectively. Furthermore, the side from the first bottom wall 11 toward the opening of the first storage section 1 may be referred to as the top, and the opposite side may be referred to as the bottom.

[0013] The first peripheral wall 12 is a cylindrical body extending upward from the periphery of the first bottom wall 11, and its upper end forms the opening of the first storage section 1. The first peripheral wall 12, together with the first bottom wall 11, defines a first storage space 15, which is a storage section for items. The first peripheral wall 12 includes a pair of first side walls 16, a first partition wall 17, a front wall 18, and a pair of first connecting pieces 19 (see FIG. 2). Note that the terms "front" and "rear" of the front wall 18 and a rear wall 28, which will be described later, are used for convenience of explanation and are not limited to use in which the front wall 18 is positioned on the front side and the rear wall 28 is positioned on the back side.

[0014] The pair of first side walls 16 are each a rectangular plate-like body. The pair of first side walls 16 have their lower edges connected to a pair of side edges of the first bottom wall 11 via folds, and face each other. The first partition wall 17 is a rectangular plate-like body whose lower edge is connected to the first bottom wall 11 via a fold. The first partition wall 17 is located between one side edge of one first side wall 16 and one side edge of the other first side wall 16. The front wall 18 is a rectangular plate-like body whose lower end is connected to the front edge of the first bottom wall 11 via a fold, and faces the first partition wall 17. The folds may be, for example, stripe-like irregularities formed in the sheet, but are not limited thereto, and may also be non-penetrating slits or indicator lines printed on the sheet to indicate where to fold.

[0015] The second storage section 2 includes a second bottom wall 21 and a second peripheral wall 22. The second storage section 2 is formed to have the same height dimension as the first storage section 1. The second bottom wall 21 is formed to have a larger dimension in the front-to-rear direction than the first bottom wall 11, and is formed to have approximately the same dimension in the left-to-right direction.

[0016] The second peripheral wall 22 is a cylindrical body extending upward from the periphery of the second bottom wall 21, and its upper end forms the opening of the second storage section 2. The second peripheral wall 22, together with the second bottom wall 21, defines a second storage space 25, which is a storage section for items. The second peripheral wall 22 includes a pair of second side walls 26, a second partition wall 27, a rear wall 28, and a pair of second connecting pieces 29 (see FIG. 2). The pair of second side walls 26 are each a rectangular plate-like body. The pair of second side walls 26 have their lower edges connected to the side edges of the second bottom wall 21 via folds, and face each other. The pair of second side walls 26 are also aligned in the front-rear direction with the pair of first side walls 16, and are each located on the same plane as the pair of first side walls 16. The second partition wall 27 is a rectangular plate-like body whose lower edge is connected to the front edge of the second bottom wall 21 via a fold. The second partition wall 27 is located between one side edge of one second side wall 26 and one side edge of the other second side wall 26. The left-right dimension of the second partition wall 27 is the same as the left-right dimension of the first partition wall 17. The outer surface of the second partition wall 27 faces the outer surface of the first partition wall 17. The upper edge of the second partition wall 27 is continuous with the upper edge of the first partition wall 17 via a fold. The rear wall 28 is a rectangular plate-like body whose lower end is continuous with the rear edge of the second bottom wall 21 via a fold, and faces the second partition wall 27.

[0017] The packaging box 100 is provided with a display unit 41 connected to the opening of the first storage unit 1 or the second storage unit 2. Information about the stored product and the like is written on the display unit 41, and by being arranged to be connected to the opening of the first storage unit 1 or the second storage unit 2, it is possible to prevent the position of the display unit 41 from being distorted due to vibrations during transportation and the like. In addition, the display unit 41 is designed to be easily visible when the lid is opened. In this embodiment, the display unit 41 is a rectangular plate-like body extending inward from the upper edge of one of the pair of second side walls 26 of the second storage unit 2.

[0018] In this way, the first storage section 1 and the second storage section 2 are continuous at the upper edges of the first partition wall 17 and the second partition wall 27, and can swing around the fold 72 located at the boundary between the upper edges of the first partition wall 17 and the second partition wall 27 as a rotation axis.

[0019] In addition, the connecting portion 3 connects the first bottom wall 11 or the first partition wall 17 of the first storage portion 1 to the second bottom wall 21 or the second partition wall 27 of the second storage portion 2, thereby regulating the swinging around the fold 72 located at the boundary between the upper edges of the first partition wall 17 and the second partition wall 27 as the pivot axis.

[0020] More specifically, the connecting portion 3 includes a slit 31 and a protruding tongue 32. The slit 31 is a cut formed in one of the first housing portion 1 and the second housing portion 2. In this embodiment, the slit 31 is formed in the rear edge of the first bottom wall 11 of the first housing portion 1, and both end portions extend in an arc-like shape located more inward than the center portion. The protruding tongue 32 is formed in the other of the first housing portion 1 and the second housing portion 2 and is inserted into the slit 31 in a direction from the outer surface toward the inner surface. In this embodiment, the protruding tongue 32 protrudes forward from the front edge of the second bottom wall 21 of the second housing portion 2 on the plane in which the second bottom wall 21 extends, and is inserted into the slit 31 formed in the first bottom wall 11 of the first housing portion 1 in a direction from the outer surface toward the inner surface of the first housing portion 1. The protruding tongue 32 includes a neck portion 35 and a head portion 36 that is wider than the neck portion 35 and has approximately the same width as the slit 31. The base end edge of head 36 extends in a direction perpendicular to the direction in which protruding tongue 32 extends. When protruding tongue 32 is inserted all the way into slit 31 and the base end edge of head 36 climbs over both ends of slit 31, the base end edge of head 36 catches on the inner surface of first housing portion 1 even if protruding tongue 32 tries to move from the inner surface toward the outer surface of first housing portion 1. This restricts movement of protruding tongue 32 in the direction from the inner surface toward the outer surface of first housing portion 1.

[0021] In this way, the first storage section 1 and the second storage section 2 are connected at one more location in addition to the upper edges of the first partition wall 17 and the second partition wall 27. This restricts swinging about the folds 72 at the upper edges of the first partition wall 17 and the second partition wall 27 as a pivot axis, and the first storage section 1 and the second storage section 2 form an article storage section that is rectangular in plan view and has a bottom. Furthermore, the first storage section 1 and the second storage section 2 can be easily connected by inserting the protruding tongue 32 into the slit 31. Note that the connecting section 3 is not limited to the above configuration. Instead of the above configuration, the first storage section 1 and the second storage section 2 may be connected by means of, for example, adhesive bonding. In this way, the packaging box 100 forms an overall storage section that is rectangular in plan view and has a bottom, and a partition is provided in the internal space to divide the storage section into two sections.

[0022] The lid body 5 is openable and closable to cover the first storage space 15 and the second storage space 25. The lid body 5 includes an upper wall 51 and a lid body peripheral wall 52.

[0023] The upper wall 51 is a rectangular plate-like body and is formed to be substantially the same as the entire openings of the first storage section 1 and the second storage section 2. That is, the upper wall 51 has a pair of side edges extending in the front-to-rear direction, a front edge connecting one end of the pair of side edges, and a rear edge connecting the other end of the pair of side edges. The rear edge of the upper wall 51 is connected to the upper edge of the rear wall 28 via a fold, and the fold located at the boundary between the upper wall 51 and the rear wall 28 serves as a pivot axis, allowing the lid of the packaging box 100 to be opened by lifting the front of the lid body 5 covering the first storage space 15 and the second storage space 25 and swinging the lid body 5.

[0024] The lid peripheral wall 52 is a frame whose upper edge is continuous with a pair of side edges and a front edge of the periphery of the top wall 51 and extends downward. The lid peripheral wall 52 includes a pair of lid side walls 56 and a lid front wall 58. The pair of lid side walls 56 are plate-shaped bodies whose upper ends are continuous with the side edges of the top wall 51. The lower end of each lid side wall 56 on the rear wall 28 side is rounded and notched, which prevents the lid side walls 56 from getting caught on the second side walls 26 when the lid 5 swings. Furthermore, when the lid 5 is placed over the first storage section 1 and the second storage section 2, the pair of lid side walls 56 are located outside the pair of first side walls 16 and the pair of second side walls 26. The height dimension of the pair of lid side walls 56 is approximately the same as the height dimension of the pair of first side walls 16 and the pair of second side walls 26, and when the lid 5 is placed over the first storage section 1 and the second storage section 2, the pair of first side walls 16 and the pair of second side walls 26 are completely covered by the pair of lid side walls 56. This allows the packaging box 100 to have a neat appearance when the lid is closed.

[0025] Fig. 2 is a front view showing an example of the configuration of the unfolded body 101 of the packaging box 100. The unfolded body 101 is formed in the shape of a single sheet, as described below. The surface shown in Fig. 2 is the surface that will mainly become the inner surface of the packaging box 100. In Fig. 2, thin lines indicate folds formed on the front or back surface.

[0026] With regard to the first storage section 1, a pair of first side walls 16 are connected to the left and right of the first bottom wall 11 via folds that extend in a straight line, a front wall 18 is connected to the front of the first bottom wall 11 via a fold that extends in a straight line, and a first partition wall 17 is connected to the rear of the first bottom wall 11 via a fold that extends in a straight line. A pair of tongue-shaped first connecting tongues 18a are connected to the left and right side edges of the front wall 18 via folds that extend in a straight line. The outer surfaces of the first connecting tongues 18a are fixed to the inner surfaces of the corresponding first side walls 16 by means of adhesion or the like, thereby maintaining the pair of first side walls 16 and the front wall 18 in a state of extending in the vertical direction.

[0027] Furthermore, with regard to the second storage section 2, a pair of second side walls 26 are continuous with the left and right sides of the second bottom wall 21 via folds that extend in a straight line, a second partition wall 27 is continuous with the front of the second bottom wall 21 via a fold that extends in a straight line, and a rear wall 28 is continuous with the rear of the second bottom wall 21 via a fold that extends in a straight line. A pair of tongue-shaped second connecting tongues 28a are continuous with the left and right side edges of the rear wall 28 via folds that extend in a straight line. The outer surfaces of the second connecting tongues 28a are fixed to the inner surfaces of the corresponding second side walls 26 by means of adhesion or the like, thereby maintaining the pair of second side walls 26 and the rear wall 28 extending in the up-down direction.

[0028] With regard to the connecting portion 3, the protruding tongue piece 32 is formed using a part of the plate-like body of the second partition wall 27. That is, a through slit extending along the periphery of the protruding tongue piece 32 excluding the base end is formed in the second partition wall 27.

[0029] Furthermore, with regard to the lid 5, a pair of lid side walls 56 are connected to the left and right of the top wall 51 via folds that extend in a straight line, and a lid front wall 58 is connected to the front edge of the top wall 51 via a fold that also extends in a straight line. A pair of tongue-shaped lid connecting pieces 58a are connected to the left and right side edges of the lid front wall 58 via folds that extend in a straight line. The outer surface of each lid connecting piece 58a is fixed to the inner surface of the corresponding lid side wall 56 by means of adhesion or the like, so that the pair of lid side walls 56 and the lid front wall 58 maintain a state of extending in the vertical direction.

[0030] The pair of first side walls 16 are formed with folding creases 16a extending obliquely upward and rearward from their front lower ends. By folding the folding creases 16a inward, the pair of first side walls 16 and the front wall 18 collapse inward. The pair of second side walls 26 are formed with folding creases 26a extending obliquely upward and frontward from their rear lower ends. By folding the folding creases 26a inward, the pair of second side walls 26 and the rear wall 28 collapse inward. Furthermore, the pair of lid side walls 56 are formed with folding creases 56a extending obliquely downward and rearward from their front upper ends. By folding the folding creases 56a inward, the pair of lid side walls 56 and the lid front wall 58 collapse inward. This reduces the height dimension of the packaging box 100 in the folded state, thereby reducing bulk.

[0031] As described above, the first peripheral wall 12 of the first storage section 1 includes a pair of first connecting pieces 19. One first connecting piece 19 includes a sidewall-side edge 19b that is continuous with the side edge of one first side wall 16 facing the first partition wall 17 via a fold line, and a partition wall-side edge 19c that is continuous with one side edge of the first partition wall 17 via a fold line. The other first connecting piece 19 includes a sidewall-side edge 19b that is continuous with the side edge of the other first side wall 16 facing the first partition wall 17 via a fold line, and a partition wall-side edge 19c that is continuous with the other side edge of the first partition wall 17 via a fold line. Each first connecting piece 19 has a fold line 19a that is located on a fold line formed when the sidewall-side edge 19b and the partition wall-side edge 19c are folded together.

[0032] As described above, the second peripheral wall 22 of the second storage section 2 includes a pair of second connecting pieces 29. One second connecting piece 29 includes a sidewall-side edge 29b that is continuous with the side edge of one second side wall 26 facing the second partition wall 27 via a fold line, and a partition wall-side edge 29c that is continuous with one side edge of the second partition wall 27 via a fold line. The other second connecting piece 29 includes a sidewall-side edge 29b that is continuous with the side edge of the other second side wall 26 facing the second partition wall 27 via a fold line, and a partition wall-side edge 29c that is continuous with the other side edge of the second partition wall 27 via a fold line. Each second connecting piece 29 has a fold line 29a that is located on a fold line formed when the sidewall-side edge 29b and the partition wall-side edge 29c are folded together. Furthermore, the pair of second connecting pieces 29 are continuous with the pair of first connecting pieces 19 via a fold line 71 that extends in a straight line. The fold line 71 between the pair of first connecting pieces 19 and the pair of second connecting pieces 29 is located on a straight line that passes through the fold line 72 between the first partition wall 17 and the second partition wall 27. In this way, the first storage section 1 and the second storage section 2 are continuous not only with the first partition wall 17 and the second partition wall 27, but also with the pair of first connecting pieces 19 and the pair of second connecting pieces 29. The pair of first side walls 16, the pair of first connecting pieces 19, the pair of second connecting pieces 29, and the pair of second side walls 26 are arranged in this order and are continuous.

[0033] The pair of first connecting pieces 19 and the pair of second connecting pieces 29 of the deployable body 101 are formed on the outer edges with finger hooks 61 recessed inward.

[0034] The packaging box 100 also includes a pair of elongated holes 4 extending along the boundary between the first storage section 1 and the second storage section 2. The pair of elongated holes 4 extend from both ends of the fold 72 between the first partition wall 17 and the second partition wall 27 to the middle of the boundaries between the pair of first connecting pieces 19 and the pair of second connecting pieces 29.

[0035] The packaging box 100 is shipped in a folded state in which each tongue of the unfoldable body 101 other than the protruding tongue 32 is fixed to the corresponding side wall and folded along each folding crease. When forming (assembling) the packaging box 100 in a usable state to store an item in the packaging box 100, a user first makes a mountain fold along the crease between the first partition wall 17 and the second partition wall 27 of the folded packaging box 100 in a plan view. The user also makes a valley fold along the crease between the first partition wall 17 and the first bottom wall 11. The user then makes a valley fold along the crease between the second partition wall 27 and the second bottom wall 21. This causes the first partition wall 17 and the second partition wall 27 to bulge upward, and the protruding tongue 32 comes off the second partition wall 27.

[0036] Next, the user places his / her fingers on the pair of finger loops 61 and raises the pair of first connecting pieces 19 and the pair of second connecting pieces 29, using the fold between the pair of first connecting pieces 19 and the first partition wall 17 and the fold between the pair of second connecting pieces 29 and the second partition wall 27 as the pivot axis. As a result, the pair of first connecting pieces 19 and the pair of second connecting pieces 29 are pulled up, causing the pair of first side walls 16 and the pair of second side walls 26 to rise, and further causing the front wall 18 and the rear wall 28 to rise.

[0037] Next, the user rotates the pair of first connecting pieces 19 and the pair of second connecting pieces 29 outward. As a result, as shown in Fig. 3, the folds 19a of the pair of first connecting pieces 19 and the fold between the first partition wall 17 and the first bottom wall 11 are valley-folded, and the folds 29a of the pair of second connecting pieces 29 and the fold between the second partition wall 27 and the second bottom wall 21 are valley-folded. The user then folds the pair of first connecting pieces 19 so that the inner surfaces of the first connecting pieces 19 on one side and the other side are in contact via the folds 19a of the pair of first connecting pieces 19, and so that the inner surfaces of the second connecting pieces 29 on one side and the other side are in contact via the folds 29a of the pair of second connecting pieces 29.

[0038] Next, the user rotates the pair of folded first connecting pieces 19 and the pair of second connecting pieces 29 until they contact the outer surfaces of the first partition wall 17 and the second partition wall 27. Furthermore, the user swings them around fold line 72 located at the boundary between the upper edges of the first partition wall 17 and the second partition wall 27 as the rotation axis, so that the outer surfaces of the first partition wall 17 and the second partition wall 27 face each other. As a result, the pair of first connecting pieces 19 and the pair of second connecting pieces 29 are folded at fold lines 71, 73 and sandwiched between the first partition wall 17 and the second partition wall 27.

[0039] Then, the user inserts the protruding tongue piece 32 into the slit 31. This restricts the swinging of the first partition wall 17 and the second partition wall 27, and maintains the assembled state.

[0040] In use, the first connecting piece 19 and the second connecting piece 29 are folded into four and sandwiched between the first partition wall 17 and the second partition wall 27, increasing the thickness of both ends of the first partition wall 17 and the second partition wall 27. However, because the elongated hole 4 is formed in the deployable body 101, in use, both ends of the upper edge of the first partition wall 17 are separated from both ends of the upper edge of the second partition wall 27, and the upper ends of the pair of first connecting pieces 19 and the pair of second connecting pieces 29 are also partially separated. As a result, the first partition wall 17 and the second partition wall 27 are distorted toward the first storage space 15 and the second storage space 25, respectively, allowing for the increase in thickness. This prevents tearing of the fold 72 between the first partition wall 17 and the second partition wall 27 and the fold 71 between the pair of first connecting pieces 19 and the pair of second connecting pieces 29.

[0041] After storing items in the first storage section 1 and the second storage section 2, the user rotates the lid 5 to cover the first storage section 1 and the second storage section 2 with the lid 5. In this way, the lid 5 is integrated with the storage sections 1 and 2, making it easy to handle the packaging box 100.

[0042] As described above, the packaging box 100 is formed by folding a sheet, and includes a first storage section 1 having a first bottom wall 11 and a first peripheral wall 12 extending upward from the peripheral edge of the first bottom wall 11 and defining a first storage space 15, which is a storage section for items, together with the first bottom wall 11; a second storage section 2 having a second bottom wall 21 and a second peripheral wall 22 extending upward from the peripheral edge of the second bottom wall 21 and defining a second storage space 25, which is a storage section for items, together with the second bottom wall 21; and a connecting section 3.
