Abstract: Disclosed is a packaging box which includes a box body. The packaging box includes a cavity defined in the box body and a side wall surrounding the cavity, a support frame that disposed on an inner side of the side wall, and a bottom plate that is disposed in the cavity and at an end of the support frame. The support frame is integrated with the box body, an opening is provided in the box body, and the support frame is formed by bending the side wall located at the opening toward the cavity.

Abstract: The invention provides a packing box and a method of using the same, comprising a base surface, side surfaces and receiving compartments; wherein the side surfaces and the base surface form first set of folding marks used to fold along the first folding marks and form a space for the packing box; a plurality of holes are opened on the base surface, and the receiving compartments are fixed on the base surface, with the holes used as openings thereof; each receiving compartment is surrounded by a plurality of wall surfaces, the wall surfaces unparallel to the base surface when the receiving compartments are expanded are defined as unparallel wall surfaces, the other wall surfaces are parallel wall surfaces, and a plurality of second folding marks are formed on the unparallel wall surfaces to be used to fold and expand the corresponding wall surfaces; wherein, when the unparallel wall surfaces are folded, the internal cavities of the receiving compartments disappear and the receiving compartments are retracted,

Abstract: The invention provides a foldable box connection structure, a foldable box and a method of using the same. The foldable box connection structure comprises a first side plate, a second side plate, a first hinge, a first top plate, a seam cover plate and a positioning plate. The first hinge is used to connect the first top plate and the second side plate. The seam cover plate can be folded to cover the first hinge, and the seam cover plate and the positioning plate are configured to secure the first hinge. The foldable box includes the above-mentioned connection structure. In the present invention, the first top plate is hooked by the first hinge and the seam cover plate, and a second top plate is hooked by a third hinge, so that the foldable box has a fixed structure.
