TECHNICAL FIELD

[0001] The utility model relates to fruit and vegetable packaging technical field especially relates to a multi -scene reusable preservation function packing box. BACKGROUND

[0002] Fruit and vegetable packing box plays a vital role in daily life and commercial circulation, they are designed for packing and protecting fresh fruits and vegetables, aiming to ensure that these products maintain the best state throughout the process from the production place to the consumer's hands, these packing boxes are usually made of sturdy and durable materials, such as hard paperboard or plastic, in order to effectively resist the external impact and extrusion that may be encountered during transportation, storage and sales process, so as to prevent fruits and vegetables from being damaged or rotten, by reducing the mutual interference between fruits and vegetables and the direct impact of external objects, fruit and vegetable packing box significantly prolongs the preservation period of fruits and vegetables, and guarantees the safety and quality of food.

[0003] However, the existing fruit and vegetable packing box has several deficiencies in design:

[0004] Firstly, the side and bottom of most packing boxes are designed flat, lacking necessary reinforcing rib structure, this design leads to the packing box to deform easily when bearing heavy objects or experiencing long-time transportation, becoming soft and weak, this condition not only reduces the overall stability of the packing box, but also increases the risk of the packing box being deformed and extruded to damage the fruits and vegetables in the case of violent shaking, thereby shortening the preservation time of fruits and vegetables;

[0005] Secondly, for small and easily damaged fruits and vegetables such as blueberries, raspberries, chickpeas, red fruit ginseng and wolfberry, the common practice is to punch a large number of holes on the cover surface and the bottom surface of the box to increase the air permeability and promote the air circulation inside the fruits and vegetables, however, this practice brings new problems: on the one hand, the punched cover surface and bottom surface often have uneven edges, these uneven edges are easy to contact with the surface of fruits and vegetables during transportation, causing scratches or damage, especially for the fragile skinned berries, this problem is particularly prominent, even the skin is broken and the juice flows out, accelerating the pollution and decay between fruits, leading to the deterioration of the fruits; on the other hand, too many through holes accelerate the evaporation of water in fruits and vegetables, leading to fruit shrinkage, seriously affecting the freshness and commodity value of fruits and vegetables, therefore, a multi -scene reusable preservation function packing box is proposed.

The elliptical box design also improves the box's capacity and stacking stability, making it suitable for various transportation and storage scenarios. It allows for a tight fit between the lid and the box body. The inner tray further enhances the stability and protection of fruits and vegetables. The fruit and vegetable groove design at the top of the inner tray accommodates fruits and vegetables of different sizes, preventing them from being squeezed or collided during transportation. The drainage holes at the bottom of the fruit and vegetable groove and the drainage channels on the inner wall help evaporate excess moisture from the surface of the fruits and vegetables, reducing the risk of rotting due to excessive moisture. Furthermore, the groove design on the outer wall of the inner tray facilitates user access, while the interference fit between the protrusion and the inner wall ensures the stability and sturdiness of the inner tray, preventing damage. Compared to traditional perforated packaging boxes, this invention effectively avoids scratches and damage to fruits and vegetables caused by uneven perforation edges during transportation, and even prevents juice leakage, which can accelerate contamination and spoilage, leading to fruit deterioration and loss of freshness. It also reduces the evaporation of internal moisture, maintaining the freshness and commercial value of the fruits and vegetables. Furthermore, it facilitates the separation of the box body and lid, improving usability and convenience. The interlocking side hole one on the top and the side hole two on the bottom of the lid not only meet the requirements for air exchange and convection within the box but also serve as a drainage channel when washing fruits and vegetables, achieving multifunctionality and practicality. In addition, the design of the placement protrusion at the bottom of the box body and the sealing limit at the top of the lid allows multiple boxes to be stacked and secured together, reducing the risk of boxes falling during shelf display and transportation, and improving the safety and stability of the packaging. This design is not only suitable for the transportation and storage of fruits and vegetables but can also be widely applied to other items requiring preservation and protection.
