The utility model has the advantages of good folding, convenient unfolding, strong bearing capacity and the like.

However, the inventor finds that the technical scheme still has at least the following defects:

this technical scheme be owing to be provided with the folding line in the both sides of box body in order to reach the folding purpose of box body, this just leads to when needs use the box body, and the box body lateral wall intensity that sets up the folding line is relatively poor.

In view of this special the utility model is put forward.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model adopts the following basic concept:

an environment-friendly glue-free easy-to-fold packaging box comprises a box body, wherein rectangular through openings are formed in the lower parts of narrow edges on two sides of the box body; a long edge of the upper part of the box body is integrally connected with a box cover, and two narrow side edges of the box body are respectively provided with two splayed folding lines; the two narrow edges of the box cover are connected with reinforced corrugated boards uniformly; lie in two narrow limit departments of box body inner chamber bottom all are fixed with spacing corrugated platform, and spacing corrugated platform and the interior space that forms of box body inner wall are with strengthen the vertical alignment of corrugated sheet.

As a preferred embodiment of the present invention, the length and width of the rectangular opening are both greater than the length and width of the limiting corrugated platform.

As a preferred embodiment of the present invention, the height of the reinforced corrugated sheet is consistent with the depth of the box body.

As a preferred embodiment of the present invention, binding paper boards are fixed on both sides of the front side of the box body; one long edge of the box cover, which is far away from the box body, is uniformly provided with a bound edge, binding lines are fixed on two edges of the outside of the bound edge, and the two binding lines are respectively aligned and matched with the two binding paper boards one by one.

As an embodiment of the present invention, the spacing corrugated platform is adapted to the thickness of the reinforced corrugated plate along the straight line distance formed between the inner wall of the box body and the box body.

Compared with the prior art, the utility model following beneficial effect has:

the utility model discloses a box body can be folded through the folding line on both sides narrow limit, when closing the lid on the box body, the enhancement corrugated sheet on lid both sides can be pegged graft in the gap that spacing corrugated table and box body inner wall formed, not only plays the fixed effect of side direction, can also form a stable side direction support to two narrow limits of box body that have the folding box, and the practicality is better, and when folding the box body, two narrow limits of box body can overlap at spacing corrugated table through the rectangle opening.

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
