[0025] The present utility model will be further described below in conjunction with the accompanying drawings:

[0026] The directions described in the specification of the present utility model, such as "upper", "lower", "left", "right", "front", "rear", etc., are all based on the directions of the accompanying drawings and are for the purpose of facilitating the description of the relationships between various components, and do not indicate the only or absolute positional relationships between various components. It is only one of the implementation manners for realizing the present utility model and is not a limitation on its implementation manners.

[0027] This embodiment provides a cigarette case with a paper-plastic structure, as Figures 1 to 6As shown in the figure, it includes a bottom tray 1, an inner lining 2, a middle cover 3 and a top cover 4. The top of the bottom tray 1 is open for the inner lining 2 to be inserted. The lower part of the inner lining 2 matches the shape of the inner cavity of the bottom tray 1. The middle cover 3 is sleeved on the top of the inner lining 2. The top cover 4 is rotatably connected to the bottom tray 1 and the top cover 4 can cover the middle cover 3. The bottom tray 1, the inner lining 2, the middle cover 3 and the top cover 4 are all integrally formed structures made by the paper-plastic molding process. Among them, the paper-plastic molding process can refer to the patent number CN202211190635.3, titled "A Preparation Process for Pulp Molding Products". The paper-plastic process is called "stereoscopic papermaking technology". Different from papermaking, it mainly uses pulp as raw material. Its manufacturing process includes: 1 breaking the raw materials in a pulper and soaking them in a pulp pool, and adding special adhesives according to the situation; 2 then lifting them up with a special mesh mold with a filter screen and squeezing them. This step can squeeze out part of the water and shape the pulp into a rough shape; 3 then transporting this shape to the final mold and continuing to squeeze it, and continuously heating during this process. Due to the plastic characteristics of paper fibers, paper-plastic can finally be manufactured; 4 finally die-cutting the edges. However, the above-mentioned two squeezing steps require the use of molds and have requirements for the demolding angle after the molds are formed. Therefore, each paper-plastic molding has a demolding angle. The paper-plastic molding process technology requires that it is impossible to achieve an undercut simply from the aspect of paper-plastic molding. Therefore, in this embodiment, the undercut is realized by changing the structural direction. That is, it is impossible to manufacture a cylindrical shape with a large middle and small ends. Through the above process, the bottom tray 1, the inner lining 2, the middle cover 3 and the top cover 4 are all integrally formed structures, and through the die-casting process, the shapes of each component are more stable, more solid and full, and the stiffness is better. In this way, a cigarette case can be made of paper-plastic, with high hardness and good precision. It can be made of environmentally friendly pulp, improving the environmental protection properties of the product. In addition, there is no need to manufacture multiple layers of paper and process them into a folded state, saving production resources. Of course, this kind of packaging box structure can be applied not only to cigarette cases but also to other products.

[0028] Preferably, as Figure 2 and Figure 5 、 Figure 6 shown, a concave first groove 31 is provided on the upper part of the middle cover 3, and a first boss 41 corresponding to the first groove 31 is provided on the inner side wall of the top cover 4.
