Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to an agricultural product packaging box with an anti-mildew structure. Background Technology

[0002] Agricultural products are susceptible to microbial contamination during post-harvest storage, transportation, and sales, leading to spoilage and causing huge economic losses and resource waste. Traditional anti-mold methods (such as chemical preservatives and low-temperature refrigeration) have problems such as high cost, chemical residues, and high energy consumption. Therefore, it is necessary to design an agricultural product packaging box with an anti-mold structure.

[0003] To address this, patent CN217049745U discloses an agricultural product packaging box, belonging to the field of packaging box technology. This agricultural product packaging box includes a box body and a lid. Ventilation holes are provided on both sides of the box body. A buffer strip and a buffer plate are fixedly connected to the inner sidewall of the box body. Second limiting plates are fixedly connected to both sides of the top of the box body. First limiting plates are fixedly connected to both sides of the bottom of the lid. Limiting strips are provided on both sides of the box body. This agricultural product packaging box, through the cooperation of the buffer plate, buffer strips, and ventilation holes, ensures good ventilation inside the packaging box while providing good protection for the agricultural products inside, preventing damage during transportation. The cooperation of the first limiting plate, second limiting plate, limiting strips, and slots makes the connection between the box body and lid more secure, ensuring that separation of the lid and box body will not damage the box body. This facilitates the recycling of the packaging box and reduces usage costs.

[0004] While the aforementioned agricultural product packaging boxes are easy to reuse during use, they are prone to developing transverse cracks after prolonged use and under load, affecting their lifespan. Therefore, it is necessary to design an agricultural product packaging box with an anti-mildew structure. Utility Model Content

[0005] The purpose of this utility model is to provide an agricultural product packaging box with an anti-mildew structure, in order to solve the defect that existing agricultural product packaging boxes are prone to transverse cracks after long-term use and weighing, which affects the service life of the packaging box.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an agricultural product packaging box with an anti-mildew structure, including a base box;

[0007] The outer side of the base box is fixed with a reinforcing structure, which includes corrugated cardboard, protective partitions and reinforcing ribs. The corrugated cardboard is fixed to the outer wall of the base box, and protective partitions are fixed to the outer wall of the corrugated cardboard. The reinforcing ribs are fixed to the inner walls on both sides of the base box.

[0008] The outer side of the protective partition is provided with a protective structure;

[0009] The top of the base box is provided with a cover, and the bottom of the protective structure is uniformly fixed with wear-resistant ribs.

[0010] Furthermore, the main cross-section of the corrugated cardboard is wavy.

[0011] Furthermore, the reinforcing ribs are evenly distributed on the inner wall of the base box.

[0012] Furthermore, the protective structure includes a connecting layer, an antibacterial layer, and a waterproof layer. The connecting layer is fixed to the outer wall of the protective partition, an antibacterial layer is fixed to the outside of the connecting layer, and a waterproof layer is fixed to the outside of the antibacterial layer.

[0013] Furthermore, the connecting layer is a non-woven fabric layer, and the antibacterial layer is a corrugated paper layer.

[0014] Furthermore, the waterproof layer is a PE membrane layer.

[0015] Furthermore, the wear-resistant ribs are evenly distributed at the bottom end of the waterproof layer.

[0016] The present invention provides an agricultural product packaging box with an anti-mildew structure, the advantages of which are:

[0017] By incorporating a reinforced structure, the corrugated cardboard's wavy structure can disperse pressure, preventing transverse cracks caused by localized stress concentration. It also forms air channels to aid in mold prevention and ventilation. Reinforcing ribs are evenly distributed on the inner wall of the box, longitudinally enhancing load-bearing capacity and preventing side wall deformation during stacking. Protective partitions serve as outer support, providing basic compressive strength. This device enables the overall reinforcement of the box, improving the safety and service life of the agricultural product packaging box with anti-mold structure during use.

[0018] By incorporating a protective structure, a flexible connecting layer that fits snugly against the outer wall of the protective partition, and an antibacterial layer impregnated with chitosan or tea tree oil microcapsules to slowly release antibacterial components and directly inhibit mold growth, while a waterproof layer blocks external moisture penetration and allows internal moisture to escape through micropores to balance humidity, the device achieves a convenient anti-mold function and improves the applicability of the agricultural product packaging box with an anti-mold structure during use.

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides an agricultural product packaging box with an anti-mildew structure, including a base box 1.

[0027] Reference Figures 3-5 The outer side of the base box 1 is fixed with a reinforcing structure 2, which includes corrugated cardboard 21, protective partitions 22 and reinforcing ribs 23. The corrugated cardboard 21 is fixed to the outer wall of the base box 1, and protective partitions 22 are fixed to the outer wall of the corrugated cardboard 21. The reinforcing ribs 23 are fixed to the inner walls on both sides of the base box 1. The main view section of the protective partitions 22 is wavy, and the reinforcing ribs 23 are evenly distributed on the inner wall of the base box 1.

[0028] The corrugated cardboard 21 and the reinforcing rib 23 form a "skeleton-rib" structure, which can improve longitudinal compressive strength and effectively solve the problem of transverse cracks after long-term weighing. The corrugated cardboard 21 and the protective partition 22 absorb a small amount of vibration energy during transportation, reducing collision damage to agricultural products. The gap between the corrugated cardboard 21 and the protective partition 22 can promote air circulation and prevent condensation from accumulating.

[0029] Reference Figures 1-5A protective structure 3 is provided on the outside of the protective partition 22. The protective structure 3 includes a connecting layer 31, an antibacterial layer 32, and a waterproof layer 33. The connecting layer 31 is fixed to the outer wall of the protective partition 22. An antibacterial layer 32 is fixed on the outside of the connecting layer 31. A waterproof layer 33 is fixed on the outside of the antibacterial layer 32. The connecting layer 31 is a non-woven fabric layer, the antibacterial layer 32 is a corrugated paper layer, and the waterproof layer 33 is a PE coating layer. A cover 4 is provided on the top of the base box 1. Wear-resistant ribs 5 are evenly fixed on the bottom of the protective structure 3. The wear-resistant ribs 5 are evenly distributed on the bottom of the waterproof layer 33.

[0030] The antibacterial layer 32 is impregnated with chitosan or tea tree oil microcapsules on both sides, which can slowly release antibacterial components to directly inhibit mold growth and kill attached mold through contact. The waterproof layer 33 is a PE coating layer. The microporous structure of the PE coating layer can block liquid water but allow water vapor to pass through, preventing a "humid" environment.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
