(Prior Art) Many different types of packaging boxes that are foldable have been proposed. however,
The number of partitions is reduced for a packaging box in which partitions forming a large number of compartments are provided integrally with the box body to facilitate folding and assembly.

Among these few proposals, a typical one is the partition box disclosed in Publication No. 54184 of 1984.

(Problems to be solved by the invention) The partition box according to the above proposal achieves the intended purpose by forming a multi-section partition integrally with the box body and making it foldable into a flat sheet. However, since the lower part of each partition piece forming the compartments is completely cut off, there is a drawback that it is difficult to assemble the glue using an automatic machine.

Also, even though it is said that it can be folded into a flat sheet, it cannot be done with the bottom formed, so after delivery the customer must form the bottom using an appropriate method such as gluing. The drawback is that it requires extra man-hours at home and increases packaging costs.

(Means for Solving the Problems) The present invention has been made by focusing on such conventional problems, and by changing the structure of the members forming the bottom and the partition, Nevertheless, it is possible to fold it, and the glue assembly operation is completely automated.
The purpose is to solve the above problems.

In the present invention, the left side plate 2, the rear plate 3, the right side plate 4, the front plate 5, and the adhesive piece 6 are sequentially connected in one horizontal direction via the polygonal line a-b. Upper and lower inner lids 7, 7', 8, 8' are connected to each other via the bending lines e and f, and a support plate 9 is connected to the upper end of the rear plate 3 via the bending line e. At the top of 9,
A partition plate 13 having at least one partition piece 12 is provided between the upper and lower fixed plates 10 and 11 in a manner that it can be raised and lowered via fold lines k and l. A fixing piece 14 is provided at the end on the left side plate 2 side via f, and a rear lower lid 16 is provided adjacent to the fixing piece 14 with a notch 15 bored on the outside. A top lid 17 having an insertion piece 18 is connected to the upper end of the plate 5 via a fold line e, and the front plate 5
At the lower end of the front lower cover 20, a fixed piece 14' is provided at the end on the right side plate 4 side via the fold line f, and a protruding piece 19 is provided at the opposite end. The lower inner cover 8 of the left side plate 2 is fixed to the fixed piece 14 of the rear lower cover 16 overlapped with the rear plate 3, and the front plate 5 overlapped with the front lower cover 20 is attached to the left and right side plates 2, 4 and the partition plate 13, and are formed by fixing the lower inner lid 8' and the fixing piece 14', the upper fixing plate 11 and the front plate 5, and the left side plate 2 and the sticking piece 6, respectively, and the protruding piece 19 and The front and rear lower lids 16, 20 can be formed into a box body with a bottom portion consisting of the front and rear lower lids 16, 20 in which the notches 15 are combined, and a plurality of compartments separated by partition pieces 12 that stand up inside. This packaging box is characterized by being foldable into a flat shape by bending it inward and inserting it between the front plate 5 and the partition piece 12. (The symbols in the text indicate the corresponding parts in the examples described later.) (Function) The packaging box has each partition piece connected and held by the upper and lower fixing plates through the fold lines, so it is easy to glue and hold by an automatic machine.
