Abstract
The invention relates to a paper board packing box capable of being opened and closed automatically. The paper board packing box has an integrated hard paper template; after the hard paper template is folded, an inner box body and an outer box body are formed; when the inner box body is pushed out along the inner wall of the outer box body, an inner box body upper board component (2) drives small folding boards (2a) to stretch out and bend downwards, the small folding boards (2a) drive a sealing board (3a) to stretch out downwards till the small folding boards (2a) are propped against by side sealing parts (2c), and a U-shaped notch (2b) forms an object taking opening; when the inner box body is pushed inwards along the inner wall of the outer box body, the inner box body upper board component (2) drives the small folding boards (2a) to stretch out and flatten upwards, the small folding boards (2a) drive the sealing board (3a) to be folded upwards till the sealing board (3a) is propped against by a side sealing part (4a) of an outer box body upper board component, and the sealing board (3a) forms a sealing opening of the paper board packing box. The paper board packing box provided by the invention is ingenious in design, convenient to use, and good in hand feeling; as the completely integrated paper board design is adopted, without split joint, so that the processing, the folding and the assembling are convenient.
