[0030] The following describes a carton structure according to an embodiment of the present utility model with reference to the accompanying drawings.

[0031] Refer to Figure 1-5 , and the present utility model aims to provide an embodiment of a carton structure.

[0032] In this embodiment, a carton structure mainly includes: an inner box body 1, which is formed by butting and splicing two U-shaped plates 11, and the opposite side edges of the two U-shaped plates 11 form an intermediate support plate 13; an outer box body 2, which surrounds the outer periphery of the inner box body 1, and is provided with a bottom plate 21 connected to the bottom surface of the inner box body 1, side plates 23 connected to the side walls of the inner box body 1, and a left cover plate 25 and a right cover plate 27 that can cover the top surface of the inner box body 1.

[0033] Specifically, for the existing single-layer carton, when used to load soft-packaged beverages, its strength and rigidity are insufficient, and it is easy to crush the products inside. The carton of the present utility model is composed of an inner box body 1 and an outer box body 2, and reinforcing ribs are added around the carton, and a support structure is added in the middle of the carton. Through the improvement of the structure, without changing the materials, the quality and performance of the carton can be improved.

[0034] In some embodiments of the present utility model, the side plates 23 are arranged on the side walls in the width direction of the bottom plate 21, and the left cover plate 25 and the right cover plate 27 are arranged on the side walls in the width direction of the side plates 23.

[0035] Specifically, the bottom surface of the inner box body 1 can be blocked by the bottom plate 21, the side surfaces of the inner box body 1 can be blocked by the side plates 23, and the top surface of the inner box body 1 can be blocked by the left cover plate 25 and the right cover plate 27. Furthermore, the inner box body 1 and the outer box body 2 can cooperate to form a rectangular carton structure.

[0036] In some embodiments of the present utility model, a bottom folding part 22 is arranged on the side wall in the length direction of the bottom plate 21, a side folding part 24 is arranged on the side wall in the length direction of the side plates 23, a left folding part 26 is arranged on the side wall in the length direction of the left cover plate 25, and a right folding part 28 is arranged on the side wall in the length direction of the right cover plate 27.

[0037] In some specific embodiments of the present utility model, the length of the right cover plate 27 is longer than that of the left cover plate 25. When the left cover plate 25 and the right cover plate 27 are closed, the left folding portion 26 and the right folding portion 28 are aligned to form a top edge reinforcing rib corresponding to the bottom folding portion 22. Longitudinal creases are provided at the joints of the bottom plate 21, the side plates 23, the left cover plate 25, and the right cover plate 27. Transverse creases are provided at the joints of the bottom plate 21 and the bottom folding portion 22, the side plates 23 and the side folding portion 24, the left cover plate 25 and the left folding portion 26, and the right cover plate 27 and the right folding portion 28. An inner folding portion 12 is provided on the side of the U-shaped plate 11 away from the middle support plate 13.

[0038] Specifically, when used after the combination of the inner box body 1 and the outer box body 2, the inner folding portion 12 can cooperate with the side folding portion 24 to form a reinforcing structure for the left and right sides of the carton, and the bottom folding portion 22, the left folding portion 26, and the right folding portion 28 cooperate to form a reinforcing structure for the upper and lower sides of the carton, so that the four sides of the carton are provided with reinforcing ribs to increase the thickness and stiffness of the four sides of the carton.

[0039] Refer to Figure 1 and Figure 3 , a chamfer 14 is provided on the outer periphery of the inner box body 1, and the chamfer 14 is provided at the joint of the U-shaped plate 11 and the inner folding portion 12.

[0040] Specifically, by providing the chamfer 14 on the outer circumference of the inner box body 1, an octagonal inner box body 1 is formed: after the inner box body 1 is combined with the outer box body 2, the internal shape changes from a rectangle to an octagon. The design of the chamfer 14 can increase the compressive resistance and stability of the carton, and at the same time enable the carton to better disperse the pressure when subjected to external forces.

[0041] Refer to Figure 1 and Figure 3 , the middle support plate 13 is located at the exact middle position inside the inner box body 1, and the thickness of the middle support plate 13 is twice that of the U-shaped plate 11.

[0042] Specifically, through the middle support plate 13, when the carton is transporting items, a supporting force can be provided in the middle of the carton. The middle support plate 13 can effectively disperse the pressure inside the carton, reduce the extrusion and deformation of the internal beverages, and thus improve the overall compressive resistance and strength inside the carton.

[0043] It should be noted that: the middle support plate 13 can be designed as a flat plate that closely fits the bottom and / or the middle of the carton to disperse the pressure inside the carton and prevent the bottom from collapsing under the pressure of heavy objects.

[0044] In the description of this specification, the description with reference to the terms "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
