Packaging box

A packaging box for accommodating a product to be packaged having at least one caster, the packaging box comprising:

• a pallet that is placed on a support surface and forms a bottom portion of an accommodating space in which the product to be packaged is accommodated;
• a first panel that is disposed to face the pallet in a vertical direction and forms an upper portion of the accommodating space;
• and
• a second panel, a third panel, a fourth panel, and a fifth panel that surround the accommodating space from four directions and each form a side portion of the accommodating space,
• wherein a slope panel, which is composed of one or more of the first panel, the second panel, the third panel, the fourth panel, and the fifth panel that belong to a panel group, includes one or more leg portions that protrude toward the accommodating space and are formed at one or more positions on a back surface of the slope panel, the back surface being one of a pair of main surfaces of the slope panel that faces the accommodating space, and
• when the packaging box is in an unpacked state in which the panels belonging to the panel group have been removed, the slope panel is connected to the pallet directly or via another member in an orientation in which the leg portions of the slope panel are in contact with the support surface, so that a slope surface of the slope panel, the slope surface being a main surface opposite to the back surface, forms a downwardly inclined surface extending from a height of an upper surface of the pallet on which the product to be packaged is placed to a height of the support surface.
