[0020] Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Reference Figures 1-7 As shown, a paper-plastic packaging structure for fragile items is used to package a bowl 2 made of glass or ceramic. The paper-plastic packaging structure includes at least two paper trays 1 with the same structure. The paper tray 1 includes an integral outer edge 10, a limiting tube and a base 14. The outer edge 10 is a closed loop structure. The limiting tube is located between the outer edge 10 and the base 14 and is an inverted structure. A plurality of the limiting tubes are arranged around the base 14 to form an open receiving cavity, that is, the opening of the limiting tube faces downward and the tube wall of the limiting tube faces upward to form an open cavity. The bowl 2 is placed on the base 14 with its opening facing downward and is limited by the open receiving cavity. Two adjacent paper trays 1 are stacked and inserted together and fixed by being tied together with ropes 3.

[0023] Because the rims of ordinary glass or ceramic products are relatively thin, they are easily damaged by bumps during transportation or handling by consumers. Moreover, the manufacturing process of these products generally requires a large draft angle, so they are usually inverted cone shapes that are wider at the top and narrower at the bottom, such as bowl 2. In view of this characteristic, the paper tray 1 of this application adopts an inverted method to protect the rim of bowl 2. Since bowl 2 products are usually sold in multiples, multiple paper trays 1 can be stacked, and ropes 3 can be fixed on paper trays 1 for easy customer pickup or transportation.

[0024] Furthermore, such as Figure 2 As shown, the limiting cylinder includes a first limiting cylinder 11, a second limiting cylinder 12, and a third limiting cylinder 13. Stepped grooves 141 are provided between the first limiting cylinder 11, the second limiting cylinder 12, and the third limiting cylinder 13, respectively. The base 14 is divided by the stepped grooves 141, leaving space at the mouth of the bowl 2, allowing the mouth of the bowl 2 to be lifted by hand at the stepped grooves 141, facilitating the handling of the bowl 2. Furthermore, the first limiting cylinder 11 and the second limiting cylinder 12 are both located at the corners of the outer edge 10, and the third limiting cylinder 13 is located at the horizontal edge of the outer edge 10. The layout of the limiting cylinders on the paper tray 1 is symmetrical, increasing the structural strength of the base 14. Figure 6 As shown, the outer edge 10 has a rectangular frame structure and the cross-section of the outer edge 10 is stepped, which is used to increase the structural strength of the outer edge 10.

[0025] Furthermore, a first groove 100 is provided on the transverse side of the outer edge 10, and a second groove 130 is provided on the third limiting cylinder 13. The paper tray 1 is wrapped and secured within the first groove 100 and the second groove 130 by a rope 3. Figure 5 As shown, for easy handling or transport and securing, the groove depth can be designed to be greater than 1 / 2 the rope diameter, providing excellent anti-slip properties. For example... Figure 2 and Figure 4 As shown, the base 14 is provided with multiple second reinforcing ribs 140 with concave and convex structures, which are radially distributed on the base 14. Furthermore, two first limiting cylinders 11 and one second limiting cylinder 12 are provided at the corner of the outer edge 10, with first reinforcing ribs 110 formed between the adjacent cylinder walls of the two first limiting cylinders 11 and the second limiting cylinder 12; the third limiting cylinder 13 is provided with stacking ribs 131 inside. Both the first reinforcing ribs 110 and the stacking ribs 131 can increase the structural strength of the limiting cylinder. To prevent the product from jamming during transportation and causing difficulty in removal, the paper tray 1 generally needs to be provided with stacking ribs 131. The stacking ribs 131 can be set inside the corresponding third limiting cylinder 13, with the upper and lower inserted paper trays 1 stacked together and separated at one of the stacking ribs 131, thus separating the two products and preventing them from being squeezed and broken.

[0026] Furthermore, the first reinforcing rib 110 and the stacking rib 131 are at the same height. Since consumers typically experience corner collisions during handling or transportation, causing product breakage, the first reinforcing rib 110 is installed at the four corners of the paper tray 1 to protect the product from damage. Its height is equal to that of the stacking rib 131, serving as a separator. The two work together to bear the load, increasing the stacking strength and preventing the product from being crushed. Specifically, two adjacent paper trays 1 are inserted together through the bottom and opening of two corresponding limiting cylinders and are blocked by the stacking rib 131.

[0027] Furthermore, the paper tray 1 is made through pulp molding. Since the raw material for pulp molding is recycled cardboard, it not only turns waste into treasure, but also allows the used packaging material to be recycled, posing almost no harm to the environment. In addition, pulp molding is a molding process, and for irregular structures, the optimal structural protection can be selected according to the product shape.

[0028] In this utility model device, the assembly and cooperation relationship of the various components, the material of the paper tray 1 and the pulp molding process are existing technologies or materials, and the relevant technical personnel can directly purchase or order them from the market according to the required product model and specifications.

[0029] The above description is merely a preferred embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It is obvious to those skilled in the art that this utility model is not limited to the details of the above embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
