This patent application claims the priority of the Chinese patent application filed on January 20, 2020 with the application number 202010064777X and the invention title "collapsible container". The full text of the above application is incorporated herein by reference.

Technical field

The invention relates to the field of logistics transportation appliances, in particular to a collapsible container.

Background technique

The foldable container is also called the foldable turnover box. The folded volume is only 1/4 of the assembled volume. It has the advantages of light weight, less space, and convenient assembly. It is widely used in a variety of closed-loop logistics distribution systems. New products that meet the environmental protection requirements of modern enterprises and the zero inventory plan.

In the existing collapsible container, the side panels are relatively unfolded and upright when in use, and the four side panels are interlocked to form a relatively closed space to contain the goods. When the goods are emptied, the box body can be folded for recycling. When the collapsible container is used to carry food such as fresh fruits and vegetables, especially when cold chain transportation is required, the relative tightness of the container is particularly important. The relative tightness of the container is poor, and the fresh food is very susceptible to contamination by the external environment during transportation, causing the food to corrode and deteriorate.

Most of the existing containers used for cold chain transportation are generally collapsible containers. Because there is a reasonable fit gap between the adjacent side panels, the fit gap is caused by the existence of the fit gap during the unfolding and use of the box. There is open energy transfer inside and outside the box, so the temperature change inside the box tends to be uncontrollable. In other words, the temperature outside the box is uncontrollable, and the temperature inside the box is more likely to be uncontrollable due to the environment outside the box, which in turn causes the food that is refrigerated and kept fresh to be more prone to spoilage or quality loss.
