Description

[Detailed description of the invention] (Industrial application field) The present invention is a packaging box that is integrated with the box body and has internal partitions that form a number of compartments, making it easy to assemble and fold. It is related to.

(Conventional technology) Regarding conventional foldable packaging boxes,
Many different types have been proposed. However, there are fewer proposals for a packaging box in which partitions forming many compartments are provided integrally with the box body, making it easy to fold and assemble.

Among these few proposals, a representative one is Publication No. 57-37707.

The proposed partition box achieves its intended purpose by allowing the partition box with many compartments to be folded into a flat sheet, but the lower part of each partition piece of the partition wall is completely cut off. Because of this, it is difficult to assemble using automatic machines and the processing costs are high.Furthermore, it is not possible to fold the product into a flat shape with the bottom formed, so customers often prefer to use products that are delivered in a flat shape. After making it into a square cube shape,
The bottom part must be fixed with glue before use, which also has the disadvantage of requiring additional man-hours for the consumer.

In order to eliminate these drawbacks, the applicant proposed a foldable packaging box with partitions according to Japanese Utility Model Application Publication No. 123422/1983.
