Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

The schematic diagrams of the four-cycle packaging box of the present invention are shown in Figures 1-7. The packaging box is formed by paper, including the left end panel 1, the rear panel 3, the right end panel 14, the front panel 24 and the flap 25 which are folded and connected in sequence. The upper side of the left end plate 1 is folded and connected with the first dustproof flap 2 , and the lower side is folded and connected with the second dustproof flap 31 . The upper side of the rear plate 3 is folded and connected with the first cover plate 6, and the lower side is folded and connected with the first bottom plate 29; the first cover is provided with a first tear strip 5, a first tear line 7, a second tear line 9 and The third tearing wire 11, the end of the first cover plate is provided with the first anti-theft tongue 8 and the first non-theft-proof tongue 10 sequentially from left to right, and the first anti-theft tongue is connected with the first tearing wire. A first slit 4 and a second slit 12 are arranged sequentially from left to right at the folded joint between the rear panel and the first cover panel. The left side of the first bottom plate is folded and connected with the first triangular plate 30 . The upper side of the right end plate 14 is folded and connected with the third dust-proof flap 13 , and the lower side is folded and connected with the fourth dust-proof flap 28 . The upper side of the front board 24 is folded and connected with the second cover board 20 , and the lower side is folded and connected with the second bottom board 26 . A second tear strip 15 , a fourth tear line 16 , a fifth tear line 21 and a sixth tear line 19 are arranged on the second cover. The end of the second cover is provided with a second anti-theft tongue 17 and a second non-theft-proof tongue 18 sequentially from left to right. The second anti-theft tongue is connected with the fourth tear wire. A third slit 22 and a fourth slit 23 are arranged sequentially from left to right at the folded joint of the second cover plate and the front plate. The left side of the second bottom plate 26 is folded and connected with the second triangular plate 27 . The bottom of the packing box is a self-locking bottom structure with high strength. The packing box can be recycled four times.

During molding, the left end plate 1, the rear plate 3, the right end plate 14, the front plate 24 and the sealing flap 25 are folded inward, and the sealing flap 25 is nailed or glued to the left end plate. Apply glue to the first triangular plate 30 and the second triangular plate 27 , bond the first triangular plate to the second dust-proof flap 31 , and bond the second triangular plate to the fourth dust-proof flap 28 . The first dust-proof flap 2 and the third dust-proof flap 13 are folded inward, the second cover 20 is folded inward, and the second non-theft-proof tongue 18 is inserted into the first slot 4 .
