[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] 1. A reinforcement plate is installed inside the carton. The reinforcement plate can increase the strength of the four edges and corners of the box body. The reinforcement plate is a hollow rectangular frame structure. While reinforcing the corners, it can also reduce the weight of the double-layer cardboard and reduce transportation costs.
[0012] 2. The outer panel and inner reinforcement plate of the carton are integrally formed from the same cardboard, so that the inner reinforcement plate is directly bent inside the outer panel, the two fit more closely, and the inner reinforcement plate is not easy to shift, making the carton more solid.

DETAILED DESCRIPTION
[0019] In the description of the present invention, it should be noted that directional words, such as the terms "center", "lateral (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present invention.
[0020] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.
[0021] See the attached drawings. The top corner reinforced logistics carton described in this embodiment includes an outer panel 1 and an inner reinforcement panel 2. The outer panel includes a left end panel 11, a front side panel 12, a right end panel 13, a rear side panel 14, and upper and lower opening and closing pages 15; the inner reinforcement panel 2 includes a first reinforcement surface 21, a second reinforcement surface 22, a third reinforcement surface 23, and a fourth reinforcement surface 24. All reinforcement surfaces are rectangular frame structures with a rectangular hollow structure in the middle. The upper and lower edges of the reinforcement surfaces are flush with the upper and lower edges of the side panels and the end panels.
[0022] The unfolded diagram of the logistics carton (such as Figure 2 As shown in FIG. 1 , a left end plate 11, a front side plate 12, a right end plate 13, a rear side plate 14, a first reinforcement surface 21, a second reinforcement surface 22, a third reinforcement surface 23, and a fourth reinforcement surface 24 are sequentially provided, and hinges 15 are also provided on the upper and lower sides of the left end plate 11, the front side plate 12, the right end plate 13, and the rear side plate 14. At the same time, a fixing surface 16 is provided on the left end plate 11, which is used to be fixed to the rear side plate by pasting or nailing, so that the paperboard is folded into a cubic structure.
[0023] After the unfolded diagram is bent (such as Figure 3 As shown), the inner reinforcement plate is folded to the inner side of the outer panel, so that the first reinforcement surface 21, the second reinforcement surface 22, the third reinforcement surface 23, and the fourth reinforcement surface 24 are placed on the inner side of the rear side plate 14, the right end plate 13, the front side plate 13, and the left end plate 11 in sequence.
[0024] And because the cardboard has a certain thickness, the length of the inner reinforcement plate needs to be smaller than the outer panel. Generally speaking, the length L4 of the first reinforcement surface and the third reinforcement surface is smaller than the length L3 of the end panel, and the difference is ≤ twice the thickness of the cardboard (2H); the length L2 of the second reinforcement surface and the fourth reinforcement surface is smaller than the length L1 of the side panel, and the difference is ≤ twice the thickness of the cardboard (2H).
[0025] The outer panel 1 and the inner reinforcement plate 2 are integrally formed from the same cardboard, and are cut, embossed, etc. according to normal carton processing technology to produce an unfolded view of the carton; the cardboard is removed, and the excess rectangular cardboard in the middle of the inner reinforcement plate is removed to form a rectangular hollow structure, and the removed cardboard can be used as an internal partition of the box; when folding the carton, the inner reinforcement plate is first folded into the inner side panel, and then folded along the creases between the left end plate, the front side plate, the right end plate, and the rear side plate, and the left end plate is fixed to the rear side plate by gluing or nailing to complete the production of the carton.
[0026] When using it, you can expand the cardboard into a cubic structure, then close the lower hinge and secure it, put the items into the carton, and finally close the upper hinge and secure it.
[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
