The accommodation space S is partitioned into four equal spaces.

  Further, for example, characters “protective sheet” are printed / marked on the outer surfaces of the partition plates 412, 422, and portions above the cut portions 411, 421 of the flaps 41, 42 are separated from the partition plates 412, 422 (protection plate). The user is informed that it can be used as a sheet. On the other hand, the remaining portions of the flaps 41 and 42 from which the partition plates 412 and 422 are cut off are referred to as remaining flaps 413 and 423.

  The height (bending length) of the third flap 43 and the fourth flap 44 is such that the upper opening (the upper surface of the accommodation space S) is closed by closing the third flap 43 and the fourth flap 44. In addition, when the third flap 43 and the fourth flap 44 are closed, the free end 431 of the third flap 43 and the free end 441 of the fourth flap 44 overlap. And the 3rd flap 43 and the 4th flap 44 are formed so that the free end part 431 of a 3rd flap and the free end part 441 of a 4th flap may engage.

  That is, as shown in FIGS. 1 and 2, the third flap 43 extends in the horizontal / width direction over the entire width at a predetermined distance from the upper edge of the third flap 43 and the fourth flap 44 and is crushed in a concave shape in the thickness direction. The bent portions 53 are formed, and the upper portions of the third bent portions 53 are free end portions 431 and 441. Further, engagement cuts 431a and 441a extending downward from the center of the upper edge of the free end portions 431 and 441 are formed. Then, while the free ends 431 and 441 are bent by the third bent portion 53, the free end 431 of the third flap 43 and the fourth end are separated from each other by the engagement notches 431a and 441a as shown in FIG. By alternately positioning (knitting) the free end portions 441 of the flaps 44 vertically, the upper opening is closed in a state where the free end portions 431 and 441 are overlapped with each other.

  Here, the opening ends of the assembly slits 412a and 422a and the engagement cuts 431a and 441a are wide open to facilitate assembly and engagement.

  Moreover, below the 1st bending part 51 of each side part 31-34, as shown in FIG.2, FIG.5, it extended in the horizontal and width direction over the full width, and the 2nd bending crushed concavely in the thickness direction. A portion (bending portion) 52 is formed, and each of the flaps 41 to 44 (including a part of each of the side surface portions 31 to 34) can be bent along the second bending portion 52. The second bent portion 52 is formed at a position that can cope with an assumed height change of the stored item in consideration of the thickness of the book that is the stored item, the number of books, and the like. That is, when the height of the stored item is normal, the flaps 41 to 44 are bent by the first bent portion 51, and when the height of the stored item is low, each flap is set by the second bent portion 52. 41 to 44 are bent. Here, when each of the flaps 41 to 44 is folded, adjacent side edges of the side surface portions 31 to 34 are separated from the first bent portion 51 to the second bent portion 52.

  On the other hand, the bottom surface portion 2 is foldable, and by folding the bottom surface portion 2, the first side surface portion 31 and the third side surface portion 33 become the second side surface portion 32 and the fourth side surface portion 34. It is supposed to overlap. That is, as shown in FIG. 2, the bottom surface portion 2 is composed of bottom plate portions 21 to 24, and each bottom plate portion 21 to 24 is formed so as to extend from the lower end edge of each of the side surface portions 31 to 34. A fourth bent portion 54 extending in the horizontal and width directions over the entire width and crushed in a concave shape in the thickness direction is formed at the boundary between the fourth bent portion 54 and the side portions 31 to 34. Can be bent.

  The first bottom plate portion 21 and the second bottom plate portion 22 are trapezoidal, and the third bottom plate portion 23 and the fourth bottom plate portion 24 are rectangular. Bending cuts 23 a and 24 a are formed on the second bottom plate portion 22 side and the first bottom plate portion 21 side of the fourth bottom plate portion 24. The bent cuts 23a and 24a are formed by a plurality of cuts and are formed so as to extend obliquely from the end portion of the fourth bent portion 54, and the triangular portions partitioned by the bent cuts 23a and 24a are joined portions. 231 and 241.

  Then, as shown in FIG. 6, the joint portion 231 of the third bottom plate portion 23 overlaps and is joined and bonded onto the second bottom plate portion 22, and the third bottom plate portion is below the first bottom plate portion 21. 23 is located on the side opposite to the joint portion 231, and the joint portion 241 of the fourth bottom plate portion 24 overlaps and is bonded and bonded onto the first bottom plate portion 21, and the fourth bottom plate is disposed below the second bottom plate portion 22. The bottom surface portion 2 is configured by being assembled so that the anti-joining portion 241 side of the portion 24 is positioned. That is, the bottom surface portion 2 is configured while the end portions of the adjacent bottom plate portions 21 to 24 are alternately overlapped with each other.

  In such a state that the bottom plate portion 2 is expanded and developed, the bottom plate portion 2 covers the lower surface of the accommodation space S without any gap. Moreover, when the center part of the baseplate part 2 is pushed up, as shown in FIG. 7, the baseplate parts 21-24 will go to the accommodation space S side, and the 3rd side part 33 and the 4th side part 34 will approach. Further, when the bottom plate portions 21 to 24 advance toward the accommodation space S side, as shown in FIG. 8, the first side surface portion 31 and the third side surface portion 33 become the second side surface portion 32 and the fourth side surface portion. It overlaps with 34. In this state, the folded bottom plate portion 2 is sandwiched between the side surface portions 31 to 34. On the other hand, when the third side surface portion 33 and the fourth side surface portion 34 are separated from each other, the bottom plate portion 2 is developed.

  In order to manufacture such a corrugated cardboard box 1 with a partitioning function, first, as shown in FIG. 2, a development material is produced by developing the corrugated cardboard box 1 with a partitioning function. At this time, the fourth side surface portion 34, the first side surface portion 31, the third side surface portion 33, and the second side surface portion 32 are arranged in this order from the left, and longitudinally bent portions 551 to 553 are interposed between each of them. Form. In addition, a first adhesive margin 71 is provided above and below the open side edge of the fourth flap 44, and a second adhesive margin 72 is provided along the entire length of the open side edge of the fourth side surface portion 34. Here, the first adhesive margin 71 is provided directly below the third bent portion 53 and directly above the first bent portion 51, and constitutes the second temporary fixing portion 62 described above. The margin 72 is provided with a second bent portion 52. Moreover, FIG. 2 has shown the outer surface side of the cardboard box 1 with a partition function.

  Next, the first bottom plate portion 21 and the second bottom plate portion 22 are bent inward (the side where the accommodation space S is formed) along the fourth bent portion 54, and the third bottom plate portion 23 and the fourth bottom plate are then bent. The joints 231 and 241 are bent to the opposite side and the outer side along the bending cuts 23a and 24a while the portion 24 is bent inward along the fourth bent portion 54. Subsequently, an adhesive is applied to the inner surface side of the joint portions 231 and 241 and the outer surface side of the adhesive margins 71 and 72, and the fourth side surface portion 34 is bent inward along the first longitudinally bent portion 551. The second side surface portion 32 is bent inward along the third vertical bent portion 553 and pressed.

  Thereby, the first glue margin 71 is joined to the second flap 42, the second glue margin 72 is joined to the second side surface portion 32, and the joint portion 241 of the fourth bottom plate portion 24 is 1 is joined to the bottom plate portion 21, and the joint portion 231 of the third bottom plate portion 23 is joined to the second bottom plate portion 22. In this state, as shown in FIG. 8, the first side surface portion 31 and the third side surface portion 33 overlap the second side surface portion 32 and the fourth side surface portion 34, and the folded bottom plate portion 2 is A bottomed cylindrical cardboard box 1 with a partition function is formed between the side surfaces 31 to 34.

  Next, the operation and usage method of the cardboard box 1 with the partition function having such a configuration will be described.

  First, when storing or transporting, as shown in FIG. 8, it is in a folded state, and in use, the third side surface portion 33 (first side surface portion 31) and the fourth side surface portion 34 (first surface portion) are used. 2, the bottom plate 2 is developed, and the cardboard box 1 with a partition function is formed into a box shape as shown in FIG. Next, as shown in FIG. 9, the upper first temporary fixing part 61 is cut off, the first partition plate 412 is cut off from the first flap 41, the upper second temporary fixing part 62 is cut off, The second partition plate 422 is cut out from the second flap 42. Then, as described above, the first partition plate 412 and the second partition plate 422 are assembled and arranged in the central portion in the accommodation space S as shown in FIG. Thereby, the accommodation space S is partitioned into four substantially equal spaces on the plane.

  Here, only the first partition plate 412 may be cut out and arranged according to the size (flat area) of the books to be accommodated, the number of books, and the like, and the accommodation space S may be partitioned into two spaces. Alternatively, the first partition plate 412 and the second partition plate 422 may be arranged independently without being assembled, and the accommodation space S may be partitioned into three spaces. On the other hand, when it is not necessary to partition the accommodation space S, the partition plates 412 and 422 are not cut off.

  After the book is stored in the storage space S partitioned in this way, as shown in FIG. 5, the temporary fixing portions 61 and 62 are separated and the remaining flaps 413 and 423 are bent inward (the storage space S side). The third flap and the fourth flap are folded and engaged with the respective free ends 431 and 441 as described above. At this time, the flaps 41 to 44 are bent by the first bent portion 51 or the second bent portion 52 in accordance with the thickness and height of the book.

  As described above, according to the cardboard box 1 with the partition function, the partition plates 412 and 422 are cut along the cut portions 411 and 421 of the first flap 41 and the second flap 42, and the partition plates 412 and 422 are Arrangement in the accommodation space S partitions the accommodation space S. That is, since a part of the first flap 41 and the second flap 42 is used as the partition plates 412, 422, it is not necessary to provide a partition plate separately from the cardboard box 1. For this reason, it is possible to reduce the labor and cost required for manufacturing, storage and transportation by suppliers and manufacturers, and it is possible to reduce the labor and cost required for storage, management and use by the user. It becomes. On the other hand, even if a part of the first flap 41 or the second flap 42 is cut off as the partition plates 412, 422, the upper opening is closed by closing the third flap 43 and the fourth flap 44. The function as a cardboard box is maintained.

  Moreover, since the accommodation space S is partitioned into four spaces by assembling the two partition plates 412 and 422 and arranging them in the accommodation space S, it is possible to increase convenience by forming a large number of accommodation spaces. By being partitioned finely, it becomes possible to more effectively prevent and suppress contact between books.

  Further, when the third flap 43 and the fourth flap 44 are closed, both free end portions 431 and 441 overlap and engage with each other, so that the third flap 43 and the fourth flap 44 Increases the strength and rigidity of the upper lid. That is, even if a part of the first flap 41 or the second flap 42 is cut off as the partition plates 412, 422, it is possible to maintain and secure the strength and rigidity necessary for the upper lid. In addition, since the remaining flaps 413 and 423 remain, the strength and rigidity of the upper lid becomes higher. Further, since the free end 431 of the third flap 43 and the free end 441 of the fourth flap 44 are not engaged and separated, the work of joining the free ends 431 and 441 with a tape or the like can be reduced. It becomes possible.

  In addition, each of the flaps 41 to 44 can be bent not only from the first bent portion 51 but also from the second bent portion 52 formed on each side surface portion 31 to 34. In other words, since there are a plurality of height positions at which each of the flaps 41 to 44 is bent, it is possible to properly accommodate the contents without any gaps by changing the folding position according to the height of the book / the contents. It becomes.

  Furthermore, the side edges of the first flap 41 and the third flap 43 are temporarily fixed by the first temporary fixing part 61, and the side edges of the second flap 42 and the fourth flap 44 are the second side. It is temporarily fixed by the temporary fixing portion 62. For this reason, the flaps 41 to 44 are not disturbed during storage, transportation, and carrying before use, and the handling becomes easy. On the other hand, in use, the flaps 41 to 44 can be individually bent by separating the temporary fixing portions 61 and 62.

  In addition, by folding the bottom surface portion 2, the first side surface portion 31 and the third side surface portion 33 overlap the second side surface portion 32 and the fourth side surface portion 34, and further, the first flap 41 and The third flap 43 overlaps the second flap 42 and the fourth flap 44. Thereby, since the whole corrugated cardboard box 1 becomes like one board, storage, transportation, etc. become easy, and it becomes possible to reduce the labor and cost required for storage, transportation, etc.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention.
