[0042] As Figs. 1 to 4The utility model provides a packing carton for fruit and vegetable storage, which comprises a carton body 1, a plurality of cover plate assemblies 2 distributed on the upper end of the carton body 1, and front, rear, left and right side plates. The utility model is characterized in that the front, rear, left and right side plates are of a composite structure to provide appropriate side cushioning protection. The outer and / or inner surface of the carton body 1 is bonded with a moisture-proof film 3, which is a polypropylene film with a thickness of 0.1-0.6 mm. This can effectively prevent the improper penetration of external water such as raindrops. The moisture-proof film 3 inside the carton body 1 can prevent the carton body 1 from being soaked when the fruit and vegetable releases moisture. The inner surface of the carton body 1 is provided with an antibacterial coating 4, which is preferably a silver ion coating with a thickness of 0.1-0.2 mm. This can prevent the occurrence of unexpected mold spots due to the presence of water vapor and bacteria. In consideration of the need for proper ventilation and respiration during the storage of fruit and vegetable, a plurality of ventilation holes 5 with a diameter of 0.5-2 mm are distributed on the side plates of the carton body 1. This can meet the ventilation requirement while preventing the intrusion of external water. During manufacturing, the ventilation holes 5 are obliquely upward from the outside to the inside, with an oblique angle of 10-40 degrees. In this way, even if there are water droplets at the ventilation holes 5, they will not flow into the carton body 1. The lower part of the outer surface of the carton body 1 is provided with a cushioning mechanism to prevent the lower end of the carton body 1 from being soaked by water vapor from the bottom or flowing water. Furthermore, a cushioning mechanism can be laid at the lower part of the inside of the carton body 1 to prevent the bottom of the fruit and vegetable from being excessively squeezed during stacking.

[0043] In a preferred embodiment of the utility model, the composite structure comprises a sandwich structure composed of a corrugated paper inner side plate 6, a foam interlayer 7 and a corrugated paper outer side plate 8. Specifically, the foam interlayer 7 is of a plate-like structure with a thickness of 1-3 mm. This provides appropriate flexible cushioning effect. In consideration of the convenience of manufacturing, an adhesive (not shown in the figure) is filled between the corrugated paper inner side plate 6, the foam interlayer 7 and the corrugated paper outer side plate 8. The thickness of the foam interlayer 7 is 1.5 mm, and the adhesive is an environmentally friendly water-based adhesive. During processing, raw materials with a similar composite structure can be directly selected, and then cut and pressed to manufacture the paper blank required for the carton body 1. Alternatively, the foam interlayer 7 and the corrugated paper inner side plate 6 can be pasted after the formation of the carton body.

[0044] Further, the air holes 5 are arranged in an array and at equal distances, so as to effectively distribute the air and reduce air dead angles. Meanwhile, the air holes 5 are in an elliptical shape, which is convenient for the tool to pierce the sandwich structure during processing, so as to effectively ventilate. After the piercing, the residual debris in the air holes 5 can be blown out by a blowing device. Through multiple comparisons, the thickness of the polypropylene film is 0.3 mm, the diameter of the air hole 5 is 1.5 mm, and the oblique angle is 35 degrees, which can be preferred. Moreover, the chamfer can be processed at the edge of the air hole 5 to avoid the falling of debris again.

[0045] In combination with the actual implementation, in order to have a proper bearing anti-deformation effect during the cushioning, the cushioning mechanism is a corrugated paper grid plate arranged in a grid, which includes a frame assembly 9, and a plurality of corrugated paper grids 10 are arranged in the frame assembly 9. In this way, relying on the grid arranged in a honeycomb or rectangular matrix, the effective bearing stress dispersion can be achieved, and collapse caused by excessive concentrated stress can be avoided. During preparation, the height of the corrugated paper grid plate is 5-10 mm, and a rubber gasket 11 is attached to the lower edge of the bottom of the corrugated paper grid plate. In this way, good anti-skid performance can be provided, and a moderate waterproof effect at the bottom can be provided to avoid the corrugated paper grid plate from absorbing water from the ground.

[0046] Meanwhile, in order to achieve the bottom cushioning of the placed fruits and vegetables, and avoid increasing the weight of the paper box, the cushioning mechanism is a foam pad 12 wrapped with a polyethylene film 13. In this way, even if the foam pad 12 is abnormally broken during use, the debris can be prevented from being adsorbed onto the surface of the fruits and vegetables. Moreover, the thickness of the foam pad 12 is 5-15 mm, which can be preferably 10 mm, so as to meet the stacking requirements of conventional fruits and vegetables.

[0047] Further, the observation holes can be provided on the front side plate, the rear side plate, the left side plate and the right side plate as needed, and transparent polycarbonate plates 14 are attached to the observation holes. In this way, the storage state of the fruits and vegetables can be checked, and external foreign matters can be prevented from entering through the observation holes. During preparation, the thickness of the transparent polycarbonate plate 14 is 0.5-2 mm. Meanwhile, considering that some fruits and vegetables release water during storage, an anti-fog coating can be sprayed on the inner side of the transparent polycarbonate plate 14.

[0048] Furthermore, in consideration of the convenience of the user to carry, the paper box body 1 is provided with a lifting rope. Meanwhile, a sheath 15 can be sleeved on the outer corner of the paper box body 1. In this way, during stacking, the abnormal deformation of the corner can be prevented, so as to prevent the paper box body 1 from improperly pressing the fruits and vegetables, and the corner can also be prevented from being damaged due to impact.
