Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a box partition that can be easily assembled and folded and that accommodates vials, drip bottles, etc., and that forms a plurality of compartments in front and rear rows. The present invention relates to a box with a partition provided integrally with a main body.

[0002]

2. Description of the Related Art Conventionally, many foldable packaging boxes have been proposed. However, there are few proposals for a packaging box in which a partition that forms many compartments is provided integrally with the box body and is easy to fold and assemble. Representative examples of these few proposals are JP-B-57-37707 and JP-B-5-4426.
There is No. 6 publication.

[0003]

The former partition box proposed above achieves the intended purpose in that it is possible to fold a partition box having a large number of compartments into a flat shape, but on the other hand Since the lower part of each partition of the partition is completely separated, there is a drawback that it is difficult to assemble with an automatic machine and requires a lot of processing man-hours.If the bottom part is formed, it can be folded into a flat shape. Since there is no more, the bottom part will be delivered to the consumer unfinished, and the consumer will be forced to assemble and use it, which is a disadvantage that extra work is required.

The latter foldable packaging box with a partition, which is proposed above, can be folded flat even if the bottom is formed. Therefore, it eliminates the disadvantage that the former consumer spends extra time. However, there is a disadvantage in that it requires a relatively large number of man-hours when gluing and assembling with an automatic machine, resulting in high processing cost. Furthermore, as is apparent in the development view, the front partition plate,
Since the front and middle partition plates and the guide plate are projected, there are disadvantages that many parts cannot be used when making a pattern from the paperboard for a box, and a lot of materials are wasted.

[0005]
