[0022] like Figures 1 to 3 As shown, an environmentally friendly corrugated cardboard box includes a box body, which is composed of two oppositely arranged long corrugated side panels 2, two oppositely arranged wide corrugated side panels 3, and two lower end covers and two upper end covers 1 respectively connected to the long side panels. The two upper end covers 1 and the lower end cover are both provided with a first groove 6 on the edge of the middle part of the box body, and a first flexible adhesive plate 7 is provided inside the first groove 6, and the first flexible adhesive plate 7 is fixed inside the first groove 6. A second groove 8 is provided in the middle part of the two wide corrugated side panels 3, and a second flexible adhesive plate 9 is provided inside the second groove 8, and the second flexible adhesive plate 9 is fixed in the second groove 8. The first flexible adhesive plate 7 and the second flexible adhesive plate 9 are arranged in a rectangular shape in the middle part of the box body, which are used as contact surfaces with the tape when the box body is packaged.

[0023] When the box needs to be packaged, the middle parts of the upper end cover 1 and the lower end cover can be bonded by wrapping the tape around the first flexible adhesive plate 7 and the second flexible adhesive plate 9, thereby achieving the purpose of packaging. At the same time, the tape is bonded to the first flexible adhesive plate 7 and the second flexible adhesive plate 9, that is, when the box is opened later, the corrugated cardboard of the box itself will not be damaged, that is, the box can be reused, which achieves the purpose of energy saving and environmental protection.

[0024] In one feasible method, an upper end cover 1, a lower end cover and a long corrugated side panel 2 located on the same side are provided with several groups of third grooves 4 along the length direction, and the third grooves 4 are U-shaped. A U-shaped flexible adhesive plate 5 is provided inside the third groove 4, and the U-shaped flexible adhesive plate 5 is fixed in the third groove 4. In this specific embodiment, the number of third grooves 4 is 4 groups, which can be determined according to the length of the box. That is, this method facilitates the reinforcement and packaging of multiple groups of tapes in the length direction of the box, thereby improving the packaging effect.

[0025] In one feasible embodiment, the side edges of the two first flexible adhesive plates 7 that are relatively arranged are both provided with a slope surface 10, and the two slope surfaces 10 form a V-shaped groove. The end of a wide corrugated side plate 3 facing the upper end cover 1 is provided with a cutting groove 11. It is not difficult to understand that when the box body is sealed with tape in the length and width directions, it is only necessary to insert a blade into the V-shaped groove to cut the tape, and then cut the tape along the cutting groove 11 to easily open the upper end cover 1, thereby improving the unpacking efficiency. At the same time, the setting of the V-shaped groove and the cutting groove 11 will not cause scratches to the first flexible adhesive plate 7 and the second flexible adhesive plate 9.

[0026] In one practicable manner, the first flexible adhesive plate 7 and the second flexible adhesive plate 9 are made of PVC soft plastic, which can be understood as a transparent flexible plastic plate in the prior art, and can reduce weight to a certain extent.

[0027] In one practicable manner, the first flexible adhesive plate 7 and the second flexible adhesive plate 9 are both fixed to the box body by gluing.

[0028] In one feasible method, corrugated support columns with a right-angled cross-section are provided at the four corners inside the box. The two side surfaces of the corrugated support columns are glued to the inner side surfaces of the box. The corrugated support group is also composed of corrugated cardboard to improve the pressure resistance and drop resistance of the four corners of the box.

[0029] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
