FIG. 10 is a perspective view of a state in which a small container and attached documents are stored in a packaging box. The following assembly order is an example, and the present invention is not limited to this.

  First, as shown in FIG. 3, the holding plate 14, the mounting plate 15, and the bottom adhesive margin plate 16 are collectively bent in accordance with the folding line p. At this time, it is desirable that the bottom bent piece 13 is slightly bent along the fold line o so that the bottom bent piece 13 can be bent inward.

  Further, the partitioning paste margin plate 17, the partition plate 18, and the rising plate 23 are collectively bent inward according to the folding line s, and the partitioning plate 18 and the rising plate 23 are bent outward according to the folding line t. In this state, the back surface adhesive portion P of the bottom adhesive margin plate 16 and the partition adhesive margin plate 17 is adhered to the front plate 2.

  Next, as shown in FIG. 4, the second lower lid 12, the holding plate 14 and the mounting plate 15 are bent inward according to the folding lines n and r, and the holding plate 14 is superposed above the partition plate 18. .

  Then, as shown in FIG. 5, the rising plate 23 is bent inward according to the folding line w, and the sticking portion P of the surface portion of the holding piece 14 is raised in a state of being superimposed above the holding piece 14. Adhere to the plate 23. At this time, it is desirable to bend it slightly according to the folding line x so that the partition part bending piece 25 can be bent inward.

  Further, the auxiliary lower lids 7a and 7b are bent inward according to the folding lines g and h, and the auxiliary lower lid adhesive margin pieces 8a and 8b are bent outward according to the folding lines i and j, so that the auxiliary lower lid 7a, 7b is polymerized respectively. Further, the first lower lid 11 is bent inward according to the folding line m.

  Finally, the first support plate 20 is bent inward according to the fold line u, the right side plate 1 is bent inward according to the fold line a, and the attachment portion P on the back surface of the auxiliary lower cover paste margin piece 8a is 2 Adhering to the lower lid 12, the rear side plate 4 is bent inward according to the folding line c, and the adhering portion P on the back surface of the auxiliary lower lid adhesive margin piece 8 b is adhered to the first lower lid 11. Thereby, it is set as the state which formed the lower cover, and the sticking part P of the surface part in the side board paste margin piece 5 is stuck on the right side board 1. FIG. Thus, it is set as the state shown in FIG. 6 by bending and sticking. In this state, the packaging box is folded in a flat shape, and the bottom cushioning portion and the partitioning portion are folded inward, so that space is not required for transportation and storage, which is very convenient.

  Next, in the state shown in FIG. 6, when a force is applied from the left and right direction of the packaging box, the right side plate 1, the front side plate 2, the left side plate 3 and the rear side plate 4 rise up to form an outer peripheral wall. Along with this, the first lower lid 11 and the second lower lid 12 to which the auxiliary lower lid paste allowances 8a and 8b are stuck are raised and combined with each other to form the box bottom, and the mounting plate The state shown in FIG. 7 is obtained in accordance with the downward pressing of 15.

  In this state, in the inside of the packaging box, as shown in FIGS. 7 to 10, the rising plate 23 is adhered to the holding plate 14, so that the partition portion and the bottom buffer portion are integrally formed. Is done. Specifically, the partition part paste plate 17 is superposed on the inner side surface of the front side plate 2 and attached, and the partition plate 18 is arranged to be substantially horizontal toward the rear side plate 4 according to the fold line t. The In addition, the bottom adhesive margin plate 16 is superposed and adhered to the front plate 2 below the front side plate 2 to which the partition portion adhesive margin plate 17 is adhered, and the mounting plate 15 is attached to the rear side plate 4 according to the broken line r. It arrange | positions so that it may become substantially horizontal toward the side. And the standing board 23 arrange | positioned so that it may become substantially perpendicular according to the broken line w may be affixed with respect to the holding plate 14 arrange | positioned so that it may become substantially perpendicular according to the broken lines p and q. The bottom buffer portion is integrally formed.

  Further, since the first support plate 20 is bent inward along the fold line u and is superimposed on the rising plate 23 at the time of folding, the rising plate 23 causes the first supporting plate 20 to be pushed downward. It is arranged so as to be pushed open to the right side plate 1 side and substantially perpendicular to the partition plate 18, and the locking piece 21 of the first support plate 20 is fitted into the notch 24 of the rising plate 23 and locked. It will be in the state. Thereby, the locking mechanism of a partition part acts and the shape of a partition part is hold | maintained.

  Further, since the second support plate 22 is superposed on the left side plate 3 without being bent like the first support plate 20 when folded, it slides as the left side plate 3 rises. Since it bends inward according to the fold line v, it will be in the state which pressed the left side board 3 outside by the restoring force, and will be in the state by which the partition part has been arrange | positioned in the approximate center position.

  Further, as shown in FIG. 9, at least the second lower lid 12 of the bottom buffer portion formed by the second lower lid 12, the holding plate 14 and the mounting plate 15 is superposed on the first lower lid 11. At the same time, the mounting plate 15 floats from the box bottom with the vertical dimension of the holding plate 14.

  Furthermore, since the vertical dimension of the second lower lid 12, the mounting plate 15 and the partition plate 18 is formed shorter than the horizontal dimension of the right side plate 1 or the like, as shown in FIGS. A predetermined gap is formed between the rear plate 4 and the rear plate 4. The gap is an accommodation space 29 for accommodating the attached document M.

  As shown in FIG. 10, the packaging box assembled in this way is in a state where the partition portion is completely raised by placing the bottom portion of the small container B on the placement plate 15, and the partition portion locking mechanism. When the small container B is fitted in the opening 19, the body of the small container B is held, and the whole is held in a state having a buffering effect. Further, the attached document M is accommodated in the accommodating space 29. That is, the small container B can be accommodated in the opening 19 while assembling the packaging box. Thereby, the working efficiency at the time of an assembly can be improved.

  When the small container B is taken out, the outer shape of the opening 19 is formed to be approximately the same as that of the small container B so as to provide a buffering effect. However, since the locking piece 21 of the first support plate 20 is fitted and locked in the notch 24 of the rising plate 23, the upward movement is restricted. Thereby, the partition plate 18 does not float up, the small container B can be taken out smoothly, and the working efficiency during use can be improved.

  Further, when the packaging box is folded at the time of disposal, the fractured portion surrounded by the weakening line 28 of the rear side plate 4 is pressed, and the lower part of the packaging box is opened by breaking along the weakening line 28. Then, the four outer peripheral walls are folded flat. Specifically, as shown in FIG. 8, the corners of the packaging box formed by the right side plate 1 and the rear side plate 4 and the corners of the packaging box formed by the front side plate 2 and the left side plate 3 are brought closer to each other. Then fold it. At this time, the bottom bent piece 13 is bent according to the folding line o, and the partitioning part bent piece 25 is bent according to the folding line x. Therefore, the bottom bent piece 13 and the partitioning part bent piece 25 are bent. In a state where the respective side surfaces of the right and left sides are prevented from coming into contact with the right side plate 1, they can be folded along the folding line while sliding. Thereby, the working efficiency at the time of disposal can be improved.

  As described above, according to the packaging box according to the present invention described above, the bottom portion of the small container B is placed in a floating state at the bottom buffer portion, and the trunk portion of the small container B is disposed at the opening 19 of the partition plate 18. Can be held. Further, when the small container B is taken out, the upward movement of the partition plate 18 is restricted by the action of the partition locking mechanism, so that the small container B can be taken out smoothly.

  Moreover, since each component board and a component piece should just be bent according to the folding lines a to x by the assembly sequence mentioned above, it can manufacture with an automatic box making machine (sack machine), and will be easy to mass-produce. .

  Example 2 of the packaging box according to the present invention will be described with reference to FIGS. The packaging box in the second embodiment is substantially the same as the structure in the first embodiment. However, the packaging box in the second embodiment is different from the first embodiment in that a plurality of openings 19 are provided in the partition plate 18 and the lower lid is locked and assembled. It is different. FIG. 11 is a back view of the packaging box in a developed state. FIG. 12 is a plan view of the assembled state of the packaging box. 13 is a cross-sectional view taken along line BB in FIG.

  As shown in FIG. 11, the packaging box in the second embodiment has 3 on the partition plate 18 by increasing the horizontal dimension of each component plate constituting the front side plate 2, the rear side plate 4, the bottom buffer portion and the partition portion. In this structure, two openings 19 are provided. Further, an abutment piece 30 that abuts against the rear plate 4 at the time of assembly is provided protruding from the upper end of the second support piece 22. In this embodiment, the shape is substantially the same as that of the locking piece 21, but the present invention is not limited to this.

  Further, a locking piece 31 protrudes from the lower end of the first lower lid 11, and the locking piece 31 is assembled by being locked into a through hole 32 provided in the second lower lid 12. In addition, a weakening line 33 is provided around the through hole 32.

  The packaging box in which the development view is formed in this manner is assembled by bending according to each fold line in the same manner as in Example 1 and attaching a predetermined portion. Then, as shown in FIGS. 12 and 13, in the assembled state, the lock mechanism acts in the same manner as in the first embodiment, and the contact piece 30 contacts the rear plate 4. Thereby, since the sliding resistance between the contact piece 30 of the second support plate 22 and the rear plate 4 has an effect like a lock mechanism, even if the lateral dimension of the partition plate 18 is large, the first The second support plate 22 side facing the support plate 20 does not float when the small container B is taken out, and the small container B can be smoothly taken out in the same manner as in the first embodiment. Furthermore, the partition bent piece 25 can be brought into contact with the rear plate 4 on the first support plate 20 side.

  Moreover, in the said Example 1 and Example 2, a bottom part buffer part and a partition part can also be provided in the right side board 1 other than the front side board 2, the left side board 3, and the rear side board 4, and the side board paste margin piece 5 is as follows. It can also be provided on the right side plate 1, the front side plate 2, and the left side plate 3 other than the rear side plate 4. That is, the accommodation space 29 is provided not only on the rear side plate 4 side but also on the left side plate 3 side, the right side plate 1 side, and the front side plate 2 side.

  Moreover, while providing the notch part 24 in the 1st support piece 20 in a partition part, and providing the latching piece 21 in the standing board 23, a locking mechanism can also be comprised and it is not restricted to this. That is, in the assembled state, if the lock plate is configured to act by being pushed open to the right side plate 1 side by the rising plate 23 in response to the downward push of the mounting plate 15. It is a good purpose.
