Description

Self-locking packing box and box blank

Technical Field

The utility model relates to a packing transportation technical field especially relates to a from locking-type packing carton and box base.

Background

Along with the rapid development of the e-commerce industry, express packaging boxes are used more and more. According to statistical data, in 2016, the express industry in China consumes 37 hundred million packing boxes and 3.3 hundred million rolls of adhesive tapes, and the folded length of the consumed adhesive tapes can be approximately 425 circles around the equator. The main material of the transparent adhesive tape commonly used for express packaging is PVC (polyvinyl chloride), the transparent adhesive tape can not be degraded after being buried in soil for 100 years, the natural environment can be seriously damaged after the transparent adhesive tape is used in a large amount, and the adhesive tape contains formaldehyde and benzene and can hurt the skin and respiratory tract of people.

The Chinese utility model patent (grant publication No. CN208647368U) discloses a self-sealing packing box without tape, which realizes self-sealing and self-locking of the packing box through the cooperation of a side inserting plate, a hook plate and an inserting tongue. The packing box is provided with a front inserting tongue and inserting tongue groove and an inner buckle sheet and buckle sheet groove, so that after the front inserting tongue is inserted into the inserting tongue groove, the inner buckle sheet is bounced to two sides through the buckle sheet groove and is clamped in the box body, and the self-sealing, self-buckling and anti-theft effects are achieved.
