A corrugated paper box with shock-absorbing effect

Technical Field

The utility model relates to the technical field of corrugated paper boxes, in particular to a corrugated paper box with shock-absorbing effect.

Background Art

Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products, and the usage has always been the first among all kinds of packaging products. Including calcium plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing performance, becoming the main force of transport packaging. In addition to protecting goods and facilitating storage and transportation, it also plays a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products, which are beneficial to the environment and convenient for loading and unloading.

The structure of corrugated boxes is divided into split-type and folding-type structures. The split-type structure usually includes a box body and an upper cover. The box body is formed by a square body made of corrugated paper, and openings are provided on both sides of the box body for easy hand lifting. It is widely used in transportation, moving, storage and other scenarios. The folding-type structure is usually an integrated form. The corrugated box can be folded and stored by folding. It is now commonly used in express packaging and other scenarios.

However, traditional split corrugated boxes cannot compress objects tightly inside the box when carrying objects for transportation, thereby failing to reduce the phenomenon of objects shaking up and down inside the box. As a result, objects are easily shaken up and down inside the box during bumpy transportation, causing collisions between the objects and the placement surface, resulting in damage to the objects.
