Description

Technical Field

[0001] The present invention relates to the technical field of turnover boxes, and in particular to a turnover box for cold chain logistics. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are acid-resistant, alkali-resistant, oil-resistant, non-toxic and odorless. They can be used to hold food, etc. They are easy to clean, and parts turnover is convenient, neatly stacked, and easy to manage. When cold chain items are delivered, ice packs are usually added to the turnover boxes to make the turnover boxes have a cold-keeping effect, and the refrigeration and heat preservation time can reach several days, thereby ensuring the quality of cold chain items and facilitating the delivery of cold chain items.

[0003] During the use of existing cold chain logistics turnover boxes, the ice bags placed inside them will melt over time, and easily cause water droplets to form on the inner wall of the box and the surface of the cold chain items. The water droplets will then fall to the bottom of the box and accumulate. However, it is difficult for existing turnover boxes to absorb or discharge the accumulated water, resulting in the interior of the turnover box being relatively humid, causing the cold chain items at the bottom of the turnover box to be easily soaked in water and rot, thereby affecting the quality of the cold chain items and being unfavorable for high-quality distribution of cold chain items.
