Description

Technical Field

[0001] The present application relates to the technical field related to corrugated cardboard, and in particular to a highly waterproof packaging carton. Background Art

[0002] The related art publication number is CN221776538U, which discloses a leakproof and waterproof corrugated cardboard box.

The leakproof and waterproof corrugated cardboard box provided by the utility model has a clamping column. When the carton is closed and used, the stretching column is pressed and the top cover is sleeved on the top of the box body. At this time, the stretching column is released, so that the spring can stretch the clamping column through the stretching rod, so that the clamping column can be limited and stuck inside the card slot, that is, the top cover is limited and fixed on the top of the box body, thereby achieving the sealing effect of the box body, avoiding the problem of damage to the box body caused by the need for adhesive tape to be used for bonding when the box body is closed, thereby improving the use efficiency of the carton.

[0003] With regard to the corrugated cardboard box in the above-mentioned technology, due to its own design characteristics, the inventors found that the box body is sealed by the top cover, and the top cover is closed by the tensile column. When the tensile column is impacted by the outside world, it is easy to cause the tensile column to detach, thereby making it impossible for the top cover to seal the box body. Utility Model Content
