Description
Technical field
The invention belongs to box technology fields, more particularly, to a kind of express delivery box.
Background technique
With the rapid development of Internet, online shopping brings great convenience to people's lives, adjoint delivery industry
Also it develops rapidly.Usually using woven bag, polybag, big envelope, carton, carton etc. as wrapping up article to be posted in delivery industry
Express delivery box, due to delivery industry heavy traffic, courier is difficult to all during transporting and sorting express delivery box
Express delivery box is handled with care, and above-mentioned express delivery box does not have good damping, buffering function, if it is frangible for being wrapped in express delivery box
Article, express delivery box easily cause breakables to damage sending to collide on the way, therefore courier or client would generally use modeling
The fillers such as strand foam, bubble chamber film are filled into express delivery box and are wrapped in around breakables.
But the filling mode of above-mentioned filler does not have standard criterion, it is difficult to play effective damping, buffering function, simultaneously
Existing express delivery box itself resists the scarce capacity of external force, and the two combined use does not have higher reliability yet, i.e., above-mentioned
For express delivery box by the deformation that will be distorted after external impacts, breakables still remain impaired risk, can not effectively protect
Protect breakables.
Summary of the invention
Good, high reliablity that technical problem to be solved by the invention is to provide a kind of damping, buffering effects and reusable
Express delivery box.
The technical scheme of the invention to solve the technical problem is: a kind of express delivery box, the box including upper end opening
