Description

[Detailed description of the invention] This invention relates to a packaging box consisting of an upper box and a lower box.
This is intended to prevent damage to the upper box by preventing the upper box from falling downward when the upper box is placed over the lower box.

Conventionally, during the packaging process on the conveyor, the upper box was completely covered with the lower box, but the lower end of the upper box got caught on the conveyor, which not only prevented smooth transportation, but also caused the upper box to overlap. There was a drawback that some of it was stored.

The present invention eliminates the above-mentioned conventional drawbacks.

One embodiment will be described below with reference to the accompanying drawings.

FIG. 1 shows a developed view, and FIG. 2 shows a tentatively assembled state.

Figures 1 and 2 show a pair of side plates 1aib on the short side of the lower box 1.
A joint piece 2゜3 is provided at each end of the joint piece 2,
3 to the inner surfaces of the pair of side plates 1c and ld on the long side, and this part is attached to the both side plates 1a.

By fixing 1b, lc, and 1d, a lower box is constructed, and a side plate 1c on the long side.

Projecting pieces 4 are integrally provided at both ends of the side plate 1d so as to project in the length direction of the side plates 1c and 1d, and when the upper box 5 is covered as shown in FIG. A space is provided between the bottom plate of the lower box 1, that is, the surface on which the lower box 1 is placed, and the lower end of the upper box 5.

As a result, the upper box 5 will not get caught on the conveyor (not shown) during transportation, and therefore will not be damaged.

It should be noted that if the height of the protruding piece 4 is set to approximately the thickness of corrugated paperboard, no problems will occur during actual shipping.

Further, in the above embodiment, the side plate 1a on the short side.

Although the joining pieces 2 and 3 are provided on the side plates 1b and the protruding pieces 4 are provided on the long-side side plates 1c and ld, they may be reversed.

Furthermore, when the lower box 1 and the upper box 5 are to be completely fixed, the protruding piece 4 may be crushed.

As explained above, according to the present invention, projecting pieces are integrally provided at each corner of the lower box, and the upper box is supported by the projecting pieces so that its lower end is above the supporting surface. It is possible to prevent the upper box from getting caught on the conveyor during conveyance and damage to the upper box thereby, which is extremely effective in practice.
