The second flap 22 has an insertion piece 23, an insertion hole 24, an engagement piece 25, an engagement hole 26, and four fold lines in the Y-axis direction at predetermined positions.

  Next, the assembly procedure of the packaging case 1 of the present invention will be described. First, as shown in FIG. 2, the folding line between the side plate 4 and the connecting plate 9 is bent, and the connecting plate 9, the side partition plate 10, and the base plate 11 are lifted upward, and then the base plate The fold line between the side partition plate 10 and the base plate 11 is bent in the direction of arrow E so that 11 is located on the opposite side of the bottom plate 2 with respect to the side partition plate 10. Then, the bent holding piece 20 is inserted into the holding opening 19 to hold the bent state of the side partition plate 10 and the base plate 11. Further, after the second flap 22 is bent into a rectangular tube shape along the fold line, the insertion piece 23 is inserted into the insertion hole 24 and the engagement piece 25 is inserted into the engagement hole 26 to form the column portion 27.

  FIG. 3 is an enlarged perspective view for explaining the insertion of the bent holding piece 20 into the holding opening 19. FIG. 3 (a) is before insertion, FIG. 3 (b) is during insertion, and FIG. ) Shows each after insertion. The procedure for inserting the bent holding piece 20 into the holding opening 19 will be described in detail with reference to FIG. When the fold line between the side partition plate 10 and the base plate 11 is bent in the direction of arrow E in FIG. 2, as shown in FIG. 3A, the holding opening 19 and the bent holding piece 20 are separated. It comes to face each other. After this state, the bent holding piece 20 is inserted into the holding opening 19.

  At this time, as described above, the length of the bent holding piece 20 in the Y-axis direction is longer than the portion of the insertion portion 19a that is formed to be the shortest in the Y-axis direction, and the bent holding piece 20 protrudes. Since it abuts on the portion 19c, the bent holding piece 20 and the protruding portion 19c are temporarily deformed as shown in FIG. When the bent holding piece 20 is completely fitted to the fixing portion 19b, the protruding portion 19c is restored to the original position by the restoring force, and as shown in FIG. It protrudes on the bending holding piece 20. Thereby, it is prevented that the bending holding piece 20 returns to the insertion part 19a side.

  And as shown in FIG.3 (c), when the bending holding piece 20 is fitted by the fixing | fixed part 19b, as mentioned above, the length of the Y axis direction of the bending holding piece 20 will approach a front-end | tip. Accordingly, the Y-axis direction both ends of the bent holding piece 20 interfere with the Y-axis direction both ends of the fixing portion 19b. The folding state of the folding line between the base plate 11 and the base plate 11 is maintained.

  Next, the side plates 3, 4 and the end plate 5 are erected vertically with respect to the bottom plate 2 from the state of FIG. 2. At the same time, the first flap 21 is bent inward so as to be along the inner surface of the side plate 3. Further, the support column 27 rises together with the end plate 5. Next, the fold line between the connecting plate 9 and the side partition plate 10 is folded to fold the side partition plate 10 and the base plate 11 in the direction of the bottom plate 2. As described above, since the folded state between the side partition plate 10 and the base plate 11 is held by the bending holding piece 20, the side partition plate 10 and the like can be easily folded. ing.

  At this time, the side plate 4, the connecting plate 9, and the side partition plate 10 are put on the support column 27 formed on the end plate 5 so that the bent state of the end plate 5 is maintained and the box is maintained. Become. As shown in FIG. 4, the inside of the box formed as described above is partitioned horizontally by the side partition plate 10 and surrounded by the side plate 3, the end plate 5, and the side partition plate 10. A first storage space S1 and a second storage space S2 surrounded by the side plate 4, the end plate 5, the connecting plate 9 and the side partition plate 10 are formed. And after forming a box, the base plate 11 is bend | folded in the arrow F direction of FIG.

  FIG. 5 is a perspective view of the packaging case showing a state in which the base plate 11 is folded into a U-shaped cross section, and FIG. 6 is a side sectional view of the packaging case (cross section AA ′ in FIG. 5). 5 and 6, the fold line between the packing object placement surface 13 and the first support part 12 and the second support part 14 is shown, and the first support part 12 and the second support part 14 are mounted on the packing object. The support plate fixing piece 11a is engaged with the slit 2a while being bent so as to stand vertically downward with respect to the mounting surface 13. As a result, a base 30 (first base) is formed in which the packing object placement surface 13 is supported substantially parallel to the bottom plate 2 by the first support part 12 and the second support part 14.

  In addition, the lower end part of the 1st support part 12 is following the side partition plate 10, and bending of the fold line between the side partition plates 10 is hold | maintained by the bending holding piece 20 as mentioned above. Therefore, the tilt of the first support portion 12 with respect to the bottom plate 2 is prevented. Moreover, since the lower end part of the 2nd support part 14 is being fixed by engagement with the support plate fixing piece 11a and the slit 2a, the inclination with respect to the baseplate 2 of the 2nd support part 14 is also prevented. Then, an object to be packed (here, a toner cartridge 32a having a width x1 and a height y1) is placed on the base 30. In order to prevent toner leakage, the toner cartridge 32a is placed on the pedestal 30 with a toner supply port (not shown) facing upward.

  FIG. 7 is a perspective view of the packaging case showing a state in which the base plate 11 is bent into a mountain shape, and FIG. 8 is a side sectional view of the packaging case (BB ′ section in FIG. 7). 7 and 8, the fold line between the package placement surface 13 and the first support portion 12 is set so that the first support portion 12 stands vertically downward with respect to the package placement surface 13. In addition, the folding line 15 of the package placement surface 13 is folded into a mountain fold, and the support plate fixing piece 11b is engaged with the slit 2b. Thereby, the base 31 (2nd base) in which the to-be-packaged goods mounting surface 13 has a predetermined angle with respect to the baseplate 2 is formed. Then, an object to be packed (here, a toner cartridge 32b having a width x2 and a height y2) is placed on the base 31. Since the pedestal 31 supports the toner cartridge 32b obliquely, toner leakage can be prevented by arranging a toner supply port (not shown) on the upper side.

  Thus, since the cross-sectional shape of the pedestals 30 and 31 seen from the end plate 5 direction also changes by changing the bent shape of the pedestal plate 11, two types of packages to be packaged with different shapes seen from the end plate 5 direction are provided. Objects can be selectively stored using the same packaging case 1. Further, since the outer size of the packaging case 1 does not change, it is not necessary to change the specifications of the container when the packaging case 1 is packed in a container during transportation or storage.

  In addition, if a plurality of fold lines 15 are provided on the package placement surface 13 and one of the fold lines 15 is selected when forming the pedestal 31, the inclination of the package placement surface 13 is set. The corner can be changed step by step. Therefore, it is possible to selectively store three or more types of objects to be packed using the same packaging case.

  Next, as shown in FIG. 9, the packaged item (the waste toner bottle 33 in this case) is stored in the second storage space S2. At this time, since the support column 27 functions as a positioning member for the waste toner bottle 33, the rattling of the waste toner bottle 33 in the second storage space S2 can be suppressed. In addition, when the waste toner bottle 33 has the protruding portion 33a, the waste toner bottle 33 can be more effectively rattled by bending the protruding piece 18 toward the opening 14 and bringing it into contact with the protruding portion 33a. Can be suppressed.

  After products (toner cartridges and waste toner bottles) are stored in the first storage space S1 and the second storage space S2, the cover plate 6 is bent in the direction of arrow G in FIGS. 5 and 7 to connect the insertion piece 7a. It inserts in the opening part 16 provided in the board 9, and inserts the insertion piece 7b so that the inner surface of the end plate 5 may be met. And the assembly of the packaging case 1 is completed by inserting the cover plate fixing piece 17 into the slit 8 provided in the insertion piece 7a from the outside.

  The present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, in the above embodiment, the side plate 4 and the side partition plate 10 can be changed. Although the second storage space S2 is formed by providing the connecting plate 9 therebetween, a configuration in which the second storage space S2 in which the side plate 4 and the side partition plate 10 are connected via the folding line is not formed is also possible. is there. Further, the folding position and size of the side partition plate 10 and the pedestal plate 11 can be changed as appropriate according to the size and number of products to be accommodated.

  Further, according to the present invention, when the side plates 301 on both sides are bent upward with respect to the bottom plate 300 as described with reference to FIG. 12 of the conventional example, the end plates 304 sandwiched between the side plates 301 are natural. Of course, it can also be applied to packaging cases that stand upright.

  The present invention provides a packaging case with improved packaging workability which can be used for a plurality of items to be packed with one type of packaging case by using it for a packaging case assembled from a single sheet such as corrugated paper.
