Abstract

The invention discloses a three-time circulating packaging paper box. The packaging paper box is formed by one page. The bottom of the packaging paper box adopts a high-strength self-locking bottom structure; the end part of a front cover plate of the packaging paper box is provided with an anti-theft mortise lock; the front cover plate is provided with a tearing line; a folding connection position of the front cover plate and a front plate is provided with an insertion gap; the end part of a rear cover plate of the packaging paper box is provided with a mortise lock; the rear cover plate is provided with two tearing lines; and a folding connection position of the rear cover plate and a rear plate is provided with an inserting gap. By adopting the three-time circulating packaging paper box, the anti-theft mortise lock of the front cover plate of the packaging paper box can be inserted into the inserting gap at the folding connection position of the rear cover plate and the rear plate,so that first-time box sealing circulation is realized; the mortise lock of the rear cover plate of the packaging paper box can be inserted into the inserting gap at the folding connection position ofthe front cover plate and the front plate to realize second-time sealing circulation; and finally, dustproof flaps of the packaging paper box are sealed by an adhesive tape, so that the third-time box sealing circulation is realized. The packaging paper box provided by the invention realizes three-time circulation, lowers the logistics cost and is simple in structure and strong in practicability;and by using the anti-theft lock, the use amount of the adhesive tape is reduced.
