Description

Cushioning device for the box

technical field

The invention relates to a cushioning device, in particular to a cushioning device for a packing box.

Background technique

When the item is being transported, due to the limited shock absorbing and buffering effect provided by the carton itself, the operator will combine the cushioning material with cushioning effect on both sides of the item and put it into the carton to prevent shaking during transportation or moving Items hit the carton and reduce forces due to vibration or impact.

However, since the cushioning material is only placed in the carton and is not connected with the carton, the carton cannot share the impact force on the cushioning material, nor can it provide additional cushioning effect. Therefore, when the carton is dropped or impacted, most of the impact force will be absorbed by the buffer material, and only a small part of the carton will share the impact force of the buffer material in a limited manner. Therefore, when the impact force is greater than the buffer capacity of the buffer material (over cushioning capacity of the cushioning material), will result in damage to the item.

In addition, when the cartons are being assembled, the operator will overlap the two adjacent sides of the cartons so as to combine the cartons. However, when the cushioning material is placed at both ends of the carton, the cushioning material plus the overlapping thickness of the carton itself will waste the cushioning space of the carton, and at the same time, the overlapping part of the carton is also repeated and wastes the carton material.

Therefore, how to develop a solution that can effectively improve the above-mentioned defects and inconveniences is an urgent and important issue for relevant operators.
