Description

Technical Field

[0001] The utility model relates to the field of packaging boxes, in particular to a foldable paper box. Background Art

[0002] A paper box is a box made of cardboard, usually used for packaging, storing and transporting various items. The material of the paper box is generally composed of multiple layers of cardboard glued together, with a certain hardness and strength, and can be used for packaging gifts. It is exquisitely designed and is often used for festival gifts, business gifts, etc. to protect the internal items from damage. The paper box has been widely used in various industries and daily life.

[0003] The paper box has been widely used in various industries and daily life. However, the current structure design of the paper box is relatively single, and the folding and unfolding processes are cumbersome and not smooth enough. This not only increases the operation time and labor intensity, but also easily causes problems such as deformation and damage of the paper box after frequent folding use, reducing the service life and reuse rate of the paper box. Therefore, we propose a foldable paper box to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a foldable paper box to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A foldable paper box includes a closed outer board. The inner wall of the closed outer board is fixedly connected with a fixed bottom board. The upper surface of the fixed bottom board is fixedly connected with a first side board. Two wing boards are fixedly connected to one side surface of the first side board away from the fixed bottom board. The back surface of the first side board is fixedly connected with a movable bottom board. The upper surfaces of the movable bottom board and the fixed bottom board are both fixedly connected with a second side board. The upper surfaces of the two second side boards are both fixedly connected with auxiliary boards. Positioning boards are fixedly connected to one side surfaces of the two auxiliary boards close to each other. An extended clamping corner is fixedly connected to the front surface of one of the auxiliary boards.

[0007] In a further embodiment, four grooves are opened on the bottom surface of the closed outer board. The inner wall of each groove is fixedly connected with an anti-slip pad, and the material of the anti-slip pad is rubber.

[0008] In a further embodiment, a group of reinforcing ribs are clamped on the inner wall of the closed outer board.

[0009] In a further embodiment, mounting blocks are fixedly connected to the right side surface of the closed outer board and the right side surface of the auxiliary board. Ties are fixedly connected to the right side surfaces of the two mounting blocks.

[0010] In a further embodiment, a brand label is provided above the closed outer plate, and the bottom surface of the brand label is fixedly connected to the upper surface of the closed outer plate.

[0011] In a further embodiment, folding lines are provided on the upper surfaces of both the movable bottom plate and the fixed bottom plate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the box shape of the device, the fixed bottom plate and the movable bottom plate serve as the bottom support of the paper box, the first side plate and the second side plate can form the side enclosures of the paper box, and the closed outer plate plays a role in external closure and protection. The auxiliary plate, the positioning plate, and the extended corner can further strengthen the structural stability of the paper box, making the structure of the paper box more stable when it is unfolded for use, not easily deformed or damaged, and capable of better bearing the weight of the internal items and external pressure. At the same time, the folding steps of the paper box are clear and simple, without complex operations and professional skills. Whether it is an operator or an ordinary user, they can quickly and easily fold the paper box, saving labor and time costs and improving work efficiency. Description of the Drawings
