AI Technical Summary
Existing packaging boxes take up a lot of space when not in use, and there is a lot of friction between the bottom plate and the product, which cannot effectively reduce space and friction when stored.
Design a packaging box with a bottom panel that can be folded into the box and fits against the inner wall of the side panel. The box body is folded into a flat shape along the side panel connection line. The bottom panel and side panel are self-locking with buckles to avoid interference. When in use, the bottom panel and side panel are spaced apart, and the bottom of the box is a flat surface that contacts the product.
This design allows the packaging box to take up less space when not in use, reduces friction between the base and the product, and eliminates the need for adhesive tape sealing, making it convenient to use.

Abstract
Claims
1. A packaging box, characterized in that, include: The box body includes four side panels connected end to end, with rotatable connections between the side panels, and the four side panels form a hollow column structure. The bottom of the box is connected to the bottom of the box body. The bottom of the box includes at least three bottom plates, which are rotatably connected to three side plates respectively. The three bottom plates can completely cover the bottom surface of the box body, and at least one bottom plate can cover at least 3 / 4 of the bottom surface of the box body. The width of each bottom plate decreases from the side connected to the side plate to the side away from the side plate. In a clockwise or counterclockwise direction, the first side of each bottom plate coincides with the bottom edge of the side plate. When in the packaging box state, the bottom plate is folded relative to the side plates, so that each bottom plate is perpendicular to the side plates, with the bottom plate with the largest area located on the innermost side.
2. The packaging box according to claim 1, wherein The base plate with the largest area is the first base plate, and at least one side of the first base plate is connected to a reinforcing plate; When in the packaging box state, the reinforcing plate is folded relative to the first bottom plate, so that the reinforcing plate and the side plate of the box body come into contact.
3. The packaging box of claim 1, wherein, At least one base plate has a notch located at a corner of the base plate.
4. The packaging box as described in claim 2, characterized in that, The bottom edges of the base plate and the side plate are rotatably connected, wherein the bottom edge of the side plate connected to the first base plate has a gap with the bottom surface of the box.
5. The packaging box of claim 2, wherein The bottom of the box includes a first bottom plate, a second bottom plate, a third bottom plate, and a fourth bottom plate, which are respectively connected to the four side plates. The first bottom plate and the third bottom plate are located on opposite sides of the box body, and the second bottom plate and the fourth bottom plate are respectively provided with connecting parts. When in the packaging box state, the connecting parts on the second and fourth base plates are respectively connected and fixed to the first and third base plates.
6. The packaging box of claim 1, wherein The packaging box also includes a lid, which is connected to the top of the box. The lid includes at least a first cover plate, which is rotatably connected to a side plate. When in the packaging box state, the first cover is folded relative to the side panel, so that the first cover covers the top surface of the box.
7. The packaging box of claim 6, wherein The cover includes a first cover plate, a second cover plate, a third cover plate, and a fourth cover plate, which are respectively connected to four side plates. The first cover plate and the third cover plate are located on opposite sides of the box body. The width of the first cover plate, the second cover plate, the third cover plate, and the fourth cover plate decreases from the side where they are connected to the side plate to the side away from the side plate. In a clockwise or counterclockwise direction, the first side of the first cover plate, the second cover plate, the third cover plate, and the fourth cover plate coincides with the top edge of the side plate. When in the packaging box state, the first cover plate, the second cover plate, the third cover plate and the fourth cover plate are folded relative to the side plate, so that each of the first cover plate, the second cover plate, the third cover plate and the fourth cover plate is perpendicular to the side plate, wherein the first cover plate is located on the innermost side.
8. The packaging box of claim 7, wherein The first cover plate is provided with a first buckle on the side away from the side plate, and the third cover plate is provided with a first groove that cooperates with the first buckle at the connection between the third cover plate and the side plate. The third cover plate is provided with a second buckle on the side away from the side plate, and the connection between the first cover plate and the side plate is provided with a second groove that cooperates with the second buckle. When in the packaging box state, the first buckle is inserted into the first slot, and the second buckle is inserted into the second slot.
9. The packaging box of claim 1, wherein The packaging box is cut and folded from a piece of corrugated paper sheet.
