Description

  The present invention relates to an assembly packaging box with a partition which is formed into a box shape by assembling paperboard, and a partition which divides the inside of the box into a plurality at the same time as assembly is formed.

  When a plurality of articles are stored inside the box, a partition is provided inside the box in order to prevent misalignment of the articles and maintain the aligned state of the articles. This type of partition is formed separately from the packaging box, and is mounted inside the box after the packaging box is formed (see Patent Document 1 below). But with this one. Since the packaging box and the partition are separate, the packaging box and the partition must be stored and assembled separately, which is inconvenient.

  Therefore, conventionally, an assembly packaging box with a partition configured so that a partition is provided inside the box by an assembly operation of the packaging box is known (see Patent Document 2 below). However, in this case, because the front plate connected to the front edge of the bottom plate, the right side plate and the left side plate connected to the left and right edges of the bottom plate are provided with portions that form partitions. The structure is complicated and the number of assembling steps is large when the partition is formed, and there is an inconvenience that requires the skill of the operator for quick assembly. In addition, since a part of the partition is connected to the front side plate, the connection state between the front side plate, the right side plate, and the left side plate becomes insufficient, and the strength of the front side plate is relatively low.

  In addition, as an assembly packaging box with a partition that is relatively easy to assemble, a vertical partition plate and a horizontal partition plate that form a partition only on the right side plate and the left side plate that are connected to the left and right edges of the bottom plate are connected, It is known that the vertical partition plate and the horizontal partition plate are bent with respect to the right side plate and the left side plate, respectively, and the inside of the box is partitioned by engaging both the horizontal partition plates with each other by cutting. See Patent Document 3 below). According to this, it becomes possible to assemble very easily, and the front side plate, the right side plate, and the left side plate can be firmly connected to obtain high strength from the front side plate. However, the inside of the box is only divided into a quadrangular portion in plan view and a U-shaped portion in plan view, and there is an inconvenience that preventing the positional deviation of each article and maintaining the alignment state are insufficient.

Japanese Patent Laid-Open No. 11-301646 Japanese Utility Model Publication No. 39-24070 Japanese Utility Model Publication No.56-10019

  In view of the above points, the present invention provides a partitioned assembly packaging box that not only is extremely easy to assemble while ensuring sufficient strength, but also can sufficiently prevent misalignment of articles accommodated therein. The issue is to provide.

  In order to solve such a problem, the present invention is an assembly packaging box with a partition which is formed into a box shape by assembling paperboard, and a partition for partitioning the inside of the box into a plurality at the same time as assembly, The left side plate and the right side plate connected to each end edge of the left side plate through the crease line are erected so as to face each other, and the front side edge of the left side plate and the right side plate are connected to each other through the crease line. The first front side plate connected to the front end edge of the bottom plate through a crease line is raised to overlap the outer side surfaces of the two front side plates, and the leading edge of the first front side plate The second front side plate provided continuously through the crease line is polymerized on the outer side surfaces of the two superposition plates, and the both superposition plates are sandwiched and held between the first front side plate and the second front side plate. The connecting plate connected to the rear edge of each of the plate and the right side plate via a crease line is bent inward at a right angle At the same time, the vertical partition plates connected to the respective leading edges of both connecting plates via crease lines are further bent inward at right angles so that the two vertical partition plates face each other, and the respective leading ends of both vertical partition plates Folding the horizontal partition plates connected to each other through the crease line in a direction to overlap each other, and engaging each other with the cuts formed in both horizontal partition plates, are formed freely in each vertical partition plate, A free piece connected to the edge of the horizontal partition plate on the vertical partition plate side via a crease line is released from the vertical partition plate, bent in the opposite direction to the horizontal partition plate, and formed at the end of each horizontal partition plate The extended part is superposed on the free piece from the outer edge of the vertical partition plate on the side of the horizontal partition plate, and the rear plate connected to the rear end edge of the bottom plate via a crease line is erected to form both connecting plates The lid plate connected to the front edge of the rear plate via the crease line is parallel to the bottom plate. Characterized by comprising by closed by bending.

  According to the present invention, the vertical partition plate and the horizontal partition plate connected to the rear end edges of the right side plate and the left side plate are bent, the notches of the horizontal partition plate are engaged with each other, and the free piece Since the partition can be formed at the same time as the assembly of the box by simply releasing it from the vertical partition plate, it can be assembled very easily. In addition, since the overlapping plate connected to the front end edges of the left side plate and the right side plate is sandwiched and held between the first front side plate and the second front side plate, the first front side plate and the second front side plate are held. The connection state of the side plate, the left side plate, and the right side plate can be firmly formed, and the strength is improved. In addition, the pair of vertical partition plates and the pair of horizontal partition plates connected to each other through a notch form not only a portion partitioned in a square shape in plan view inside the box, but also by the free piece, The left and right sides of the horizontal partition plate are extended, and three spaces can be partitioned via the vertical partition plate between the left side plate and the right side plate inside the box. According to this, for example, six articles can be divided into three by a horizontal partition plate and a pair of free pieces, and with a small number of partition sections, it is possible to efficiently prevent misalignment of the articles and maintain the aligned state. be able to. In addition, since each free piece is superposed on the extending portion formed at the tip of each horizontal partition plate, inadvertent bending of the free piece is restricted, so that the partition state can be reliably maintained.

  In the packaging box of the present invention, the rear side plate and the lid plate are folded back outwardly from the bottom plate, and a protruding piece projecting from the tip of the lid plate is inserted into a locking hole formed in the bottom plate. By doing so, it is possible to display the articles inside the box with high visibility as an inclined posture in which the front side is downward while the inside of the box is exposed. And at this time, since the position shift in the front-rear direction of the articles stored inside the box is prevented by the vertical partition plate, the horizontal partition plate, and the free piece, for example, it is easy to crush vegetables such as packed vegetables Even if it exists, when it becomes an inclination posture, an upper article contacts a lower article, and an alignment state is maintained reliably without being crushed. Moreover, even if only the lower article is removed from the inside of the box among the upper and lower articles partitioned by the free piece, the downward bending of the free piece is restricted by the extending portion at the tip of the horizontal partition plate. As a result, the upper article does not fall down along the inclined bottom plate, and an excellent display can be performed while maintaining the alignment of the articles inside the inclined box.

The first vertical partition plate 20 is formed with a first free piece 22 that can be freely released from the first vertical partition plate 20 by a score line w. One side of the first free piece 22 is connected to the first horizontal partition plate 21 by a crease line p. In the present embodiment, since the shape of the plurality of articles housed inside the box body 1 is all the same, the first vertical partition plate 20 is half the length of the left side plate 13, and the first vertical partition plate 20 and the 1st connection board 19 are formed in the same length dimension. The first horizontal partition plate 21 is formed to have a longer dimension than the first vertical partition plate 20, and a portion extending longer than the first vertical partition plate 20 is a first extending portion 23. And the 1st free piece 22 is formed in the dimension longer than the 1st extension part 23. FIG. Further, a first cut 24 is formed on one side of the first horizontal partition plate 21 in the center in the length direction.

  Similarly, a second connecting plate 25 is connected to the rear side edge of the right side plate 14 via a crease line q, and the second vertical plate is connected to the front end edge of the second connecting plate 25 via a crease line r. A partition plate 26 is provided continuously. A second horizontal partition plate 27 is connected to the front end edge of the second vertical partition plate 26 via a crease line s. The second vertical partition plate 26 is formed with a second free piece 28 that can be freely released from the second vertical partition plate 26 by a cut line x. One side of the second free piece 28 is connected to the second horizontal partition plate 27 by a crease line t. And the 2nd connection plate 25, the 2nd vertical partition plate 26, the 2nd horizontal partition plate 27, and the 2nd free piece 28 are the 1st connection plate 19, the 1st vertical partition plate 20, and the 1st horizontal partition plate, respectively. 21 and the same size as the first free piece 22. Further, the second horizontal partition plate 27 has a portion extending longer than the second vertical partition plate 26 as a second extending portion 29, and is located on one side of the center in the length direction of the second horizontal partition plate 27. Is formed with a second cut 30 that engages with the first cut 24 of the first horizontal partition plate 21.

  When assembling into a box shape from the unfolded state shown in FIG. 2, first, the left side plate 13 and the right side plate 14 are erected from both sides of the bottom plate 3 so as to face each other, and the first overlapping plate 17 and the second overlapping plate 18 are moved. Bend inward at right angles (along fold line a). Next, the first front plate 4 is erected from the front edge of the bottom plate 3, and the second front plate 5 is folded inside the first front plate 4 to sandwich the first overlapping plate 17 and the second overlapping plate 18. At this time, by engaging the convex portion 6 of the second front side plate 5 with the convex portion locking hole 7, the first superposed plate 17 and the second superposed plate 18 by the first front side plate 4 and the second front side plate 5.
