BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a box-shaped body integrally provided with a cross-shaped partition, simply by folding a single corrugated board having creases or cuts at predetermined plural locations along the folds. The present invention relates to a packing tray with a partition, which is suitable for the purpose of use, such as folding the packed strawberry all at once and packing the packed strawberries in groups of four.

[0002]

2. Description of the Related Art The applicant of the present invention first disclosed an invention relating to a packing tool for packing the above-mentioned packed strawberry and the like in "Patent application 3-
Patent applications have been filed as "299947" and "Japanese Patent Application No. 3-359200".

SUMMARY OF THE INVENTION In the above two prior inventions, each of the trays has a cross-shaped partition which is integrally formed by bending only one corrugated board along the fold line. Since it folds up at once, it has the excellent feature that unlike the conventional technology, the complicated work of incorporating separately made partitioning materials into the folded tray can be saved, and a remarkable reduction in packaging cost can be achieved. I have it. When it is desired that all four outer peripheral surfaces of the tray folded up in a box shape be used as printing surfaces for displaying the product name, the place of origin, and the like, it is necessary to print corrugated cardboard on two sides. This is because, of the four outer peripheral surfaces, one of the two opposing surfaces is originally the front surface of the cardboard and the other two opposing surfaces are originally the back surfaces of the cardboard. The cost required for double-sided printing of corrugated board is naturally higher than that for single-sided printing. Therefore, an object of the present invention is to make all four outer peripheral surfaces of the tray the printing surface, which is a difficulty of the above-mentioned two prior inventions in which the tray with a partition is configured to be folded up from one cardboard. It is an object of the present invention to provide a packaging tray with a partition, which can solve the problem that double-sided printing is required because one-sided printing is not enough for corrugated board.
