Title:
SELF-SEALING PACKAGING BOX
Document Type and Number:
WIPO Patent Application WO/2020/087789
Kind Code:
A1
Abstract:
Provided is a self-sealing packaging box. When one end of a box body needs to be sealed, only a first lining board (200), a second lining board (300) and a third lining board (400) all cover one end of the box body, a first plug connector is switched to a folding position and inserted into the box body from a first socket (310) so that a first panel (100) finally covers one end of the box body and the first plug connector is automatically unfolded to an unfolding position so as to be snap-fitted in the first socket, thus achieving a self-sealing function. A box sealer does not need to seal a box with an adhesive tape, which is environment-friendly. Moreover, the packaging box has the self-sealing function, and the box cannot be opened by hand after box sealing is completed, so that the integrity of goods in the box body is guaranteed; particularly in the express industry, when a buyer receives the goods, if the packaging box is intact, it can be determined that the goods are complete, and if the packaging box has a box opening mark or is damaged, it can be determined that the packaging box has been unpacked.
