Technical Field

[0001] The utility model relates to the field of foam packing boxes, in particular to a combined foam packing box. Background Technique

[0002] Packing boxes are mainly for facilitating transportation, loading and unloading, and warehousing. Generally, they are classified into paper packing boxes, wooden packing boxes, metal packing boxes and foam packing boxes according to the materials. Among them, the foam packing box is a packing container made of foam plastics.

[0003] When the existing packing boxes are in use, when there are too many items, multiple packing boxes may be needed for placement. However, the existing technology can only be packed individually, which is inconvenient to use and prone to loss of items. Moreover, the sealing covers of the packing boxes of the existing devices are generally directly stuck on the packing boxes, with poor stability. Therefore, the technical personnel in the field provide a combined foam packing box to solve the problems raised in the above background technique. Content of the Utility Model
