Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-3This utility model provides a technical solution: a cherry packaging box that is easy to stack, including a packaging box body 1. The packaging box body 1 includes an integrated base plate 11, two first side plates 12 and two second side plates 15. A connecting plate 13 is provided at the end of the first side plate 12. A locking block 14 is provided above the connecting plate 13. A folding plate 16 is provided on the outside of the second side plate 15. A surrounding plate 17 is provided at the end of the folding plate 16. A groove 18 is provided on the inner side of the folding plate 16. The packaging box body 1 can be folded into a cubic shape, and the locking block 14 can be inserted into the groove 18. A receiving groove 21 corresponding to the position of the locking block 14 is provided at the bottom of the packaging box body 1.

[0018] The interlocking structure of the card blocks and grooves solves the problem of unstable stacking of traditional packaging boxes. The assembly time of a single box is less than 2 minutes, and the stacking layer can reach 10 layers. The damage rate is reduced, effectively reducing transportation costs. The foldable design compresses the transportation volume to a smaller volume, solving the problem of high transportation costs of traditional packaging boxes. Transportation costs are reduced, and transportation and space utilization are facilitated. The flat folding design increases the loading capacity of a single truck, improves space utilization, and reduces warehousing costs. The multi-layer composite structure solves the problem of cherries being susceptible to moisture and mold. The moisture permeability is lower than that of traditional packaging, and the compressive strength is high, which can withstand the pressure of multi-layer stacking.

[0019] In the above solution, the main body 1 of the packaging box sequentially includes an outer layer 101, a waterproof layer 102, a reinforcing layer 103, and an inner layer 104. This four-layer composite structure design solves the problems of poor moisture resistance and easy deformation in traditional cherry packaging boxes. The outer layer uses high-strength kraft paper to provide basic protection; the middle layer of PE film forms a continuous waterproof layer, effectively blocking external moisture penetration; the honeycomb paper reinforcing layer enhances compressive strength through its hexagonal structure, preventing collapse during stacking; and the inner layer of EVA foam provides soft cushioning, reducing collision damage to cherries during transportation. This composite structure enables the packaging box to combine moisture resistance, compressive strength, and cushioning functions, meeting the needs of long-distance transportation and warehousing.

[0020] In the above solution, a positioning block 19 is provided at the bottom of the main body 1 of the packaging box, and a positioning groove 2 is provided at the top of the main body 1 of the packaging box to engage with the positioning block 19. The engagement design of the positioning block 19 and the positioning groove 2 solves the problem of misalignment during stacking. The positioning block 19 protrudes from the four corners of the bottom of the box, and the positioning groove 2 is correspondingly provided at the top of the box. When stacked, the positioning block of the upper box is precisely embedded into the positioning groove 2 of the lower box, forming a physical limit. This structure ensures that each layer of packaging boxes is vertically aligned, avoids lateral displacement, and ensures stacking stability, making it particularly suitable for mechanized warehousing and transportation scenarios.

[0021] In the above solution, the folded panel 17 is fixed by adhesive bonding. The panel 17 uses an environmentally friendly adhesive bonding process, solving the problem of loosening in traditional folding structures. After the folding panel is folded to a vertical position, the panel 17 is bonded to the edge of the side panel with high-strength adhesive, forming a rigid connection. This adhesive bonding process eliminates the need for metal connectors, maintaining a clean appearance, improving the overall strength of the packaging box, and facilitating recycling and disassembly, thus conforming to the concept of green packaging.

[0022] In the above design, ventilation holes are provided on the main body 1 of the packaging box. The ventilation hole design addresses the problem of excessively high local humidity caused by cherry respiration. Appropriately distributed ventilation holes allow air circulation, reducing the carbon dioxide concentration inside the box and delaying cherry ripening and mold growth. The ventilation holes are positioned to avoid the reinforcing and waterproof layers, ensuring breathability without compromising structural strength and moisture resistance.

[0023] In the above solution, the outer layer 101 is kraft paper, the waterproof layer 102 is PE film, the reinforcing layer 103 is honeycomb paper, and the inner layer 104 is EVA foam. This material selection addresses the problem of limited material choices in traditional packaging. Kraft paper is low-cost and biodegradable, meeting environmental requirements; PE film has excellent moisture resistance, with a significantly lower moisture permeability than ordinary packaging materials; honeycomb paper achieves high compressive strength through lightweight construction; and EVA foam is soft and elastic, providing cushioning protection. The synergistic effect of these multiple materials ensures performance while controlling costs.

[0024] In the above design, the ventilation holes are 5mm in diameter and 50mm apart, distributed on the side panels of the main body 1 of the packaging box. Optimizing the ventilation hole parameters resolves the conflict between air permeability and structural strength. A reasonable hole diameter and spacing ensures sufficient air exchange while avoiding weakening the side panel strength due to excessively large openings. The even distribution of ventilation holes on the side panels ensures airflow circulation within the box, inhibits mold growth, and extends the shelf life of the cherries.

[0025] Working principle:

[0026] This type of easily stackable cherry packaging box unfolds into a flat main body 1. The second side panel 15 is folded upwards until it is perpendicular to the base plate 11, and the surrounding panel 17 is glued to form a cubic frame. Then, the locking blocks 14 of the first side panel 12 are precisely inserted into the grooves 18 of the second side panel 15, and quick assembly is achieved using elastic locking. The entire process requires no tools and can be completed by a single person.

[0027] When stacked, the positioning block 19 at the bottom of the upper packaging box is embedded into the positioning groove 2 at the top of the lower box, forming a "mortise and tenon" connection. At the same time, the card block 14 of the upper box is inserted into the receiving groove 21 at the bottom of the lower box. The double limiting ensures that the center of gravity is vertical when stacked, avoiding slippage or tilting between layers.

[0028] When not assembled, the main body of the packaging box 1 can be folded into a flat shape, significantly reducing its space occupation and facilitating bulk transportation and warehousing. Upon arrival at its destination, it can be quickly restored to its three-dimensional shape with simple folding and snapping, significantly reducing logistics and time costs.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
