DETAILED DESCRIPTION

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 4 As shown, the outer box liner integrated packaging box includes a rectangular corrugated paper box body 1 with a hollow interior, a bottom plate portion 2 and a cover plate portion 7. Four rectangular lining members 3 are arranged near the bottom plate portion 2 of the box body 1. The width of the lining member 3 is less than one-third of the length of the edge of the box body 1 opposite thereto, thereby ensuring the stability of the overall structure of the packaging box. The box body 1, the bottom plate portion 2, the lining member 3 and the top plate 71 are folded from the same packaging board, which reduces additional lining materials, improves packaging operation efficiency, saves production costs, reduces the difficulty of classified recycling, and improves Overall environmental efficiency, when the side wall of the box body 1 and the bottom plate part 2 are in the same plane, the bottom plate part 2 is provided with eight long strip-shaped cracks 5 extending to the side wall of the box body 1, and the cracks 5 are perpendicular to the bottom edge of the box body 1. The lining part 3 is folded inward along the bottom edge of the box body 1 through the cracks 5 to form a groove 4, and the lining part 3 protrudes into the box body 1 to act as a lining. The compression resistance of the one-piece lining is better than that of the split folding lining, which helps to support and fix the items inside, reduce the shaking of the items inside, and thereby reduce the risk of damage to the items inside and the box body 1.

[0023] like Figure 1 As shown, the groove 4 is connected to the inside of the box 1, increasing the air flow channel between the inside and outside of the box 1. When the items inside are fruits, increasing proper ventilation through the groove 4 can limit the accumulation of harmful gases in the box 1, such as excessive ethylene gas that promotes ripening, thereby extending the shelf life of the fruit, and can also reduce the generation of condensation water caused by temperature differences, thereby reducing the risk of fruit rot. The groove 4 at the bottom of the box 1 can also provide a stable and comfortable gripping point, allowing people to easily lift and move the box 1 by hand buckles, which helps to facilitate transportation and further improves the stacking stability and compatibility with mechanized handling.

[0024] like Figure 2 , Figure 4 and Figure 5As shown, the bottom plate 2 includes a T-shaped bottom plate 1 21, a convex bottom plate 22 and two lower side plates 23. The end of the lower side plate 23 close to the bottom plate 1 21 is rectangular, and the end close to the bottom plate 22 is triangular. The end of the bottom plate 1 21 away from the box body 1 is cut into a long strip-shaped plug-in piece 211. When spliced, the lower side plate 23 is located between the bottom plate 1 21 and the bottom plate 22. The bottom plate 22 and the two lower side plates 23 form a plug-in interface 6, and the length of the plug-in piece 211 is greater than the length of the plug-in interface 6. The bottom plate 22 is lightly pressed and the plug-in piece 211 is slightly bent, so that the plug-in piece 211 can be smoothly inserted. It is plugged into the plug-in port 6 and is not easy to fall apart, thereby maintaining the connection state of the bottom plate 2, thereby ensuring the normal use of the packaging box and transporting and protecting the contents. A plurality of lugs 221 are fixedly connected to the end of the bottom plate 22 away from the box body 1. The lugs 221 are located on both sides of the plug-in port 6. The lugs 221 and the connector 211 jointly clamp the lower side plate 23, further strengthening the connection strength of the packaging box. The depth of the groove 4 is equal to the distance between the lug 221 and the side wall of the box body 1. The lug 221 plays a certain supporting role on the lining 3, thereby reducing the risk of deformation of the lining 3.

[0025] like Figure 3 , Figure 4 and Figure 6 As shown, the top plate 71 includes a plurality of top plates 71 and upper side plates 72. A long buckle plate 711 is cut at one end of the top plate 71 away from the box body 1, and a long buckle groove 721 is opened on the upper side plate 72. When packaging, the buckle plates 711 extend into the box body 1 from the buckle groove 721 and abut against each other. Through the arrangement of the buckle plates 711 and the buckle groove 721, the packaging box can be sealed automatically without the use of tape.

[0026] Working principle: Figure 1-Figure 6 As shown, the packaging box with the unsealed top and bottom ends is enclosed into a rectangular parallelepiped with a hollow interior, the bottom plate 2 is facing upward, and the bottom plate 22, the two lower side plates 23 and the bottom plate 1 21 are folded inward in sequence. While folding, the lining member 3 connected to it is pressed inward along the bottom edge of the box body 1, and the lining member 3 is recessed inward to form a groove 4. The bottom plate 22 is lightly pressed, and the plug-in component 211 is slightly bent so that the plug-in component 211 can be smoothly inserted into the plug-in port 6. After the plug-in is completed, the lug 221 and the plug-in component 211 jointly fix the bottom plate 2, so that the bottom plate 2 can bear the weight and maintain the connection state. Flip the packaging box over, with the cover plate portion 7 facing upwards, first fold the two upper side plates 72 inwards, then fold the two top plates 71 inwards, insert the buckle plates 711 into the buckle grooves 721 of the two upper side plates 72, and the two top plates 71 are abutted against each other, thereby sealing and forming. By providing an inner lining member 3 that is integrated with the outer box, the packaging cost of the lining is reduced. The inner lining member 3 plays a certain supporting and fixing role for the items inside, and through the structural setting of the bottom plate portion 2 and the cover plate portion 7, the packaging box can be packaged without tape, thereby reducing the consumption of tape and further reducing the waste of materials.
