wherein the packaging box includes four side panels and four upper panels each extended from the four side panels,
the upper panels include a first pair of two of the upper panels opposite to each other and a second pair of two of the upper panels opposite to each other and placed perpendicular to the first pair of the upper panels,
the first pair of the upper panels are placed on the second pair of the upper panels and bonded to each other by the adhesive tape as their end portions are in contact with each other,
the second pair of the upper panels include end portions opposite to each other, the rod members are provided for the respective upper panels,
the cutting device is provided to cut the adhesive tape bonding the first pair of the upper panels to each other, and
