Description

Technical Field

[0001] This utility model relates to the field of electronic product packaging box technology, and in particular to a cardboard box. Background Technology

[0002] Cardboard boxes are a common packaging material widely used in daily life and business activities. Their main function is to protect and store items, while also serving a certain display purpose. Cardboard boxes are usually made of cardboard or cardboard, which have a certain degree of hardness and toughness and can withstand a certain weight and pressure.

[0003] Existing cardboard boxes, such as those with internal fixed-installation dividers to isolate space, have potential drawbacks such as complex structure, high production cost, and limited material adaptability. Their performance may be affected in extreme temperature and high humidity environments, and long-term use of flexible cards may cause the fixing mechanism to fail. Therefore, there is a need for a low-cost and unique cardboard box that integrates functionality, aesthetics, and structural stability. Utility Model Content

[0004] The main objective of this invention is to provide a cardboard box that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A cardboard box includes a top, a window on the front of the top, a rear insert edge fixedly connected to the inner wall of the window, a first side panel fixedly connected to one side of the top, a second side panel fixedly connected to the other side of the top, a sealing piece fixedly connected to the upper surface of both the first and second side panels, and a front insert edge fixedly connected to the upper surface of the sealing piece.

[0006] In order to achieve the effect of sealing the opening of the cardboard box, as a cardboard box of this utility model, a front cover is fixedly connected to the upper surface of the box top, and a rear cover is fixedly connected to the lower surface of the box top.

[0007] In order to facilitate the placement of the cardboard box on a flat surface, as a cardboard box of this utility model, a bottom is fixedly connected to one side of the first box, and a connecting edge is fixedly connected to one side of the bottom of the box.

[0008] In order to achieve the effect of dividing the internal space of the cardboard box into layers, as a cardboard box of this utility model, an inner partition is fixedly connected to one side of the connecting edge, and a support surface is fixedly connected to one side of the inner partition.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This cardboard box, with its top, window, rear insert edge, sealing plate, front insert edge, first box side, and second box side, folds along the intersecting lines starting from the first box side until the inner partition is folded inside the box. This divides the cardboard box into two layers: the upper layer holds the product, and the lower layer holds components. The upper space consists of the window and the inner partition, containing an attached rear insert edge and another front insert edge located within the window after being folded by the sealing plate. The product is fixed within the upper space of the window, its position defined by the rear and front insert edges. The insert edges on the packaging box are precisely sized and shaped to match the USB interface, ensuring a secure insertion without damaging the interface, preventing product rotation, and ensuring clear visibility of the brand logo.

[0010] 2. This cardboard box is integrally molded using 420g / m² FSC-certified grey board paper. Laser die-cutting and pre-crimping processes create a three-dimensional structure of individual sheets of paper, forming a self-locking honeycomb reinforcing rib inside. Material around the windows is retained, and widened nail holes are used for connection. This prevents material breakage during the gluing process, simplifying the overall assembly process, reducing material and process complexity, and effectively controlling costs.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example like Figure 1-3As shown, a cardboard box includes a box top 1, a window 2 on the front of the box top 1, a rear insert edge 3 fixedly connected to the inner wall of the window 2, a first box side 8 fixedly connected to one side of the box top 1, a second box side 9 fixedly connected to the other side of the box top 1, a sealing piece 5 fixedly connected to the upper surface of both the first box side 8 and the second box side 9, and a front insert edge 6 fixedly connected to the upper surface of the sealing piece 5.

[0015] In practical use, the cardboard box is folded from the first box side 8 along the intersecting line by setting up the top 1, window 2, rear insert edge 3, sealing piece 5, front insert edge 6, first box side 8, and second box side 9. The cardboard box is divided into two layers: the upper layer holds the product, and the lower layer holds the components. The upper space is composed of window 2 and inner partition 12. There is an attached rear insert edge 3 and another front insert edge 6 located inside window 2 after being folded by sealing piece 5. The product is fixed in the upper space of window 2 and its position is defined by the rear insert edge 3 and the front insert edge 6. The insert edge on the packaging box is precisely matched with the USB interface in size and shape to ensure that it is stable after insertion, will not damage the interface, prevents the product from rotating, and ensures that the brand logo is clearly visible.

[0016] In this embodiment, a front cover 4 is fixedly connected to the upper surface of the top of the box 1, and a rear cover 7 is fixedly connected to the lower surface of the top of the box 1.

[0017] In practical use, the opening of the cardboard box is closed by setting the front cover 4 and the rear cover 7.
