In the case of a conventional packaging box partition that has a structure in which a plurality of partition plates are simply combined in a cross-girder shape, the assembly work at the packaging work site is inefficient. Generally, it cannot be folded after assembling, and a lot of space is required for storage until it is used for packaging work.

Moreover, in the partition body in which the bottom plate portion and the partition plate can be connected and folded, the storage space is small, but a plurality of notches for inserting the partition plate into the bottom plate portion when used as a partition for a packaging box. Therefore, the shape retaining ability of the partition body is low, and the bottom plate does not reach the entire bottom surface of the storage unit. It is difficult to protect new products.

The present invention can be folded in a state where the partition structure is maintained even after assembly which solves the problem of description, and when used as a partition, the partition of the packaging box which forms the bottom plate over the entire bottom surface of the storage unit Provide the body.

The present invention includes a bottom plate portion covering the entire bottom surface of the storage portion, having only one crease for folding in the vertical direction at the center of the bottom plate portion, and having no other cuts, and two parallel and connected to the bottom plate portion. A bottom plate portion formed by a partition plate portion, a plurality of vertical partition plates having a single fold for folding in the height direction at the center, and perpendicular to the partition plate portion, and a plurality of horizontal partition plates intersecting with each other. The present invention also provides a partition for a packaging box that can be folded while the partition structure is maintained after folding by folding the folds of the vertical partition plate.

The present invention avoids the assembly work at the packaging work site, which causes a reduction in the efficiency of the packaging work site by folding the product while preliminarily assembling the product and holding the partition structure. This is a packaging box partition that can reduce the storage space until the time.

In the present invention, since the bottom plate portion without any cuts extends over the entire bottom surface of the storage portion after assembly, the shape retaining ability of the partition body is high, and it is uniform with respect to the impact from the bottom surface on the product stored in the storage portion. It is a partition of a packaging box having a proper buffer function.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 9.

The assembly method will be described below. As shown in FIG. 4, after the partition plate portion (3) connected to both lateral ends of the bottom plate portion (6) provided on the bottom plate (1) of FIG. 1 is bent through the crease (2), Grooves (9) provided downward in the height direction at both ends of the horizontal partition plate (8) of 2 and grooves (4) provided upward in the height direction in the partition plate portion (3) of the bottom plate (1) Plug in. At this time, the projecting portion provided at the upper end of the groove (4) of the partition plate portion (3) of the bottom plate (1) in the groove (10) provided upward in the height direction at both ends of the horizontal partition plate (8). When (5) is caught, the horizontal partition plate (8) is prevented from coming off. In the same way, as shown in FIG. 5, a plurality of horizontal partition plates (8) are sequentially inserted and fixed in the vertical direction.

After fixing the horizontal partition plate (8), as shown in FIG. 4, the vertical partition plate (14) of FIG. 3 is provided with a groove (15) provided downward in the height direction in the horizontal partition plate (8). It is inserted into a groove (11) provided upward in the vertical direction. At this time, the protrusion (12) provided at the upper end of the groove (11) of the horizontal partition plate (8) is caught in the groove (16) provided upward in the height direction at the upper end of the vertical partition plate (14). This prevents the vertical partition plate (14) from coming off. In the same manner, a plurality of vertical partition plates (14) are sequentially inserted and fixed in the horizontal direction.

FIG. 6 is an overall perspective view of the partition body of the packaging box assembled by inserting a plurality of horizontal partition plates (8) and vertical partition plates (14) into the bottom plate.
