In a packaging box such as Patent Document 1, the box body is only composed of perforations of division guide lines for dividing into two individual packaging boxes. Therefore, the box body may be inadvertently bent at the divided position. For example, if an external force is applied by hitting an obstacle during transportation, the box body may be bent in two at the perforation. If the box body is bent in two, the stored items stored in the storage section may fall.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a packaging box capable of making it difficult to inadvertently bend at a divided position of a box body.

The packaging box for solving the above problems includes a box main body and a partition member for partitioning the inside of the box main body, and the box main body has a bottom wall and a peripheral wall erected around the bottom wall. By arranging the partition member between a set of opposite first side walls in the peripheral wall, the first storage portion and the second storage portion are partitioned, and the bottom wall is the same as the first storage portion. A first break portion is provided at a position serving as a boundary with the second storage portion, and each of the first side walls facing each other is composed of an inner wall and an outer wall, and is formed by at least one of the inner wall and the outer wall. A second fractured portion is provided at a position extending the first fractured portion, and the partition member includes a first partition wall and a second partition wall that are overlapped with each other, and the first partition wall and the first partition wall and the partition member are provided. Each of the second partition walls includes an insertion portion inserted between the inner wall and the outer wall, and the second break portion is configured to be less likely to break than the first break portion.

According to the above configuration, the second fractured portion is more difficult to break than the first fractured portion. Therefore, it is possible to prevent the packaging box from being inadvertently bent in two at the position of the first breaking portion by applying an external force by hitting an obstacle or the like during transportation.

In the packaging box, a pair of second side walls of the peripheral wall different from the opposite first side wall are provided with an extension portion extending in the direction of the first side wall, and the insertion at the position of the opposite first side wall. The portion may be configured to be engaged with the extension portion.

According to the above configuration, by engaging the insertion portion and the extension portion, the partition wall may fall down regardless of whether the packaging box is in the state before separation or the individual packaging box. , The position is less likely to shift with respect to other walls.

In the packaging box, the insertion portion and the extension portion may be engaged with each other between the inner wall and the outer wall. According to the above configuration, the portion where the insertion portion and the extension portion are engaged can be hidden.

In the packaging box, the first fractured portion is composed of a cutting guide line in which linear cuts are discontinuously arranged, and the second fractured portion is discontinuously arranged with key-shaped bent cuts. It may be configured between two planned cutting lines. According to the above configuration, both the first fractured portion and the second fractured portion can be easily manufactured. The cutting guide line is, for example, a perforation, and the two planned cutting lines are a zipper, for example.

In the packaging box, the upper end portion of the second break portion is a positioning portion that protrudes from the upper edge portion of the pair of first side walls, and the lower side of the second break portion is provided with a positioning hole. May be good. According to the above configuration, the packaging boxes can be stacked in a stable posture by engaging the positioning portion of the lower packaging box with the positioning hole of the upper packaging box.

In the packaging box, in the partition member, the boundary between the first partition wall and the second partition wall is a third break portion, and the first partition wall and the second partition wall are the third break portion. The partition member may be arranged on the first broken portion on the box body with the third broken portion on the lower side.

According to the above configuration, the third fractured portion is positioned so as to be in contact with the first fractured portion. Therefore, when the packaging box is separated into individual packaging boxes, the first fractured portion and the third fractured portion can be fractured at almost the same time, and the work efficiency can be improved.

According to the present invention, it is possible to prevent the box body from being inadvertently bent in two.

Next, a method of separating the packaging box 10 into the first individual packaging box 8x and the second individual packaging box 9x will be described. As shown in FIG. 6, the zipper is cut off at the second fractured portion 28 of the opposite first side walls 12 and 13. As a result, the box body 11 is in a state in which the outer walls 22a and 23a of the first side walls 12 and 13 are separated into two, and the bottom wall 16 is only connected by the first break portion 17. The partition member 41 is in a state in which the first partition wall 42 and the second partition wall 43 are connected by the third fractured portion 44.

Then, as shown in FIG. 7, the bottom wall 16 is cut at the first fractured portion 17 and separated into a first bottom wall 8a and a second bottom wall 9a. At the same time, in the partition member 41, the first partition wall 42 and the second partition wall 43 are also separated by the third break portion 44. As a result, as shown in FIG. 8, the packaging box 10 is separated into a first individual packaging box 8x and a second individual packaging box 9x. In the first individual packaging box 8x, one of the second side walls is composed of the first partition wall 42, and in the second individual packaging box 9x, one of the second side walls is composed of the second partition wall 43.

According to the packaging box 10 as described above, the effects listed below can be obtained.
(1-1) The second broken portion 28 is formed of a zipper that is less likely to break than the first broken portion 17 formed of perforations. Therefore, it is possible to prevent the packaging box 10 from being inadvertently bent in two at the position of the first breaking portion 17 due to an external force applied to an obstacle or the like during transportation.

(1-2) The first grooves 26b, 27b and the second grooves 42b, 43b are engaged with the extension portions 26a, 27a of the second side walls 14 and 15 and the insertion portions 42a, 43a of the partition walls 42, 43. It is connected by. Therefore, regardless of whether the packaging box 10 is in the state of the first individual packaging box 8x and the second individual packaging box 9x, the partition walls 42 and 43 may fall down, or the second side walls 14, 15 and the like may be collapsed. The position is less likely to shift with respect to the wall.

(1-3) By sandwiching the connecting position between the extension portions 26a, 27a and the insertion portions 42a, 43a between the outer walls 22a, 23a and the inner walls 22c, 23c, the portion can be hidden.
(1-4) The extension portions 26a and 27a can support the top walls 22b and 23b from the back side at a portion closer to the fifth ruled line 35 than the first grooves 26b and 27b. Further, the insertion portions 42a and 43a can support the top walls 22b and 23b from the back side at a portion closer to the sixth ruled line 36 than the second grooves 42b and 43b.

(1-5) The first side walls 12 and 13 facing each other have a multi-layered structure in which extension portions 26a and 27a and insertion portions 42a and 43a are interposed between the outer walls 22a and 23a and the inner walls 22c and 23c. Therefore, the strength of the opposing first side walls 12 and 13 can be made higher than the strength of the opposing second side walls 14 and 15.

(1-6) Both the first broken portion 17 formed of perforations and the second broken portion 28 formed of zippers can be easily manufactured.
(1-7) By providing the positioning portion 28a and the positioning hole 28b in the portion of the second breaking portion 28, the packaging boxes 10 can be stacked in a stable posture.

(1-8) The positioning portion 28a and the positioning hole 28b can be continuously formed with the zipper of the second breaking portion 28.
(1-9) The third fractured portion 44 of the partition member 41 is adjacent to the bottom wall 16 and adjacent to the first fractured portion 17. Therefore, when the packaging box 10 is separated into the first individual packaging box 8x and the second individual packaging box 9x, the first breaking portion 17 and the third breaking portion 44 can be broken in one operation, that is, almost at the same time. This makes it possible to improve the efficiency of the separation work of the packaging box 10.

(1-10) Since the position where the first individual packaging box 8x and the second individual packaging box 9x are separated is the double of the first breaking portion 17 and the third breaking portion 44, an external force is carelessly applied. It becomes difficult to divide even if is added.
