[0002] Currently, blister packaging boxes are widely used for the transfer and storage of small and loose items. However, in actual use, it has been found that the blister packaging boxes currently in use are often one-piece molded structures, which can meet the needs of use.
[0003] The description of a novel combined blister packing box (publication number CN206634360U) mentions that "the top cover and bottom plate are parallel and coaxially distributed, with the top cover located directly above the bottom plate. Positioning connection grooves and bearing holes are evenly distributed on the top cover and bottom plate, with the positioning connection grooves and bearing holes located at the edges of the lower surface of the top cover and the upper surface of the bottom plate, respectively. The connection grooves are closed annular structures surrounding the axis of the top cover and bottom plate. There are at least four bearing holes on both the top cover and bottom plate, and the bearing holes on both the top cover and bottom plate are evenly distributed around the axis of the top cover and bottom plate and connected to each other by the connection grooves. The bearing holes on the top cover and bottom plate are coaxially distributed. Several side plates are perpendicularly connected to the top cover and bottom plate through the connection grooves." However, the packaging box in the prior art is not convenient for ventilation and drainage, and the lid is not stable, affecting the safety and stability of the packaged goods. It is not convenient to use and is not durable. Utility Model Content
