Description

Technical Field

[0001] The utility model belongs to the technical field of packaging boxes, and specifically relates to a packaging box. Background Art

[0002] The market's requirements for environmental protection of packaging materials are increasing day by day, and green, low-carbon and environmentally friendly will become the mainstream of the future development of the packaging industry. As a packaging material, paper has the characteristics of easy degradation, recyclability and low cost, which is in line with my country's goals of energy conservation, emission reduction and sustainable development.

[0003] Existing packaging boxes often adopt a drawer type to improve their convenience of disassembly and assembly and their aesthetics, but there is usually no self-locking structure between the drawer and the cover box, which may cause the product to vibrate during transportation and cause the drawer to slide out, thereby causing the product in the box to scatter. In addition, the moisture-proof effect of existing paper boxes is limited. For some food packaging (such as tea, etc.), the product is easily affected by moisture and affects the product quality. Summary of the invention

[0004] The utility model aims to provide a packaging box, which can prevent the packaging box from falling off through a simple locking structure, and also transfer the dehumidification function to the box body, thereby improving the dehumidification effect of the product packaged.

[0005] The purpose of the utility model is achieved as follows: a packaging box, comprising an outer box body and a drawer box, wherein an opening is arranged at one end of the outer box body, an opening is arranged at the top of the drawer box, and the drawer box is inserted into the outer box body, and a self-locking structure for preventing the drawer box from sliding out is arranged between the outer box body and the drawer box;

[0006] Notches are provided at the middle positions of the two side walls of the outer box body near one end of the opening. The self-locking structure includes a fixing plate and a limiting protrusion. The fixing plate is connected to the notch. The limiting protrusion is provided on the outer walls of the two sides of the drawer box and corresponds to the position of the fixing plate. An adsorption component for preventing the self-locking structure from loosening is also provided between the fixing plate and the limiting protrusion.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] 1. By setting the fixing plate and the limiting protrusion, when the packaging box is used, after the drawer box is inserted into the outer box body, the fixing plate is rotated so that the hanging hole is hung on the outside of the limiting protrusion, thereby playing a limiting and fixing role between the drawer box and the outer box body, preventing the drawer box from sliding out due to vibration during transportation and causing the products in the box to scatter, and the coordinated setting of the iron sheet and the magnetic block makes the coordination between the fixing plate and the limiting protrusion more stable, further improving the fixing stability of the packaging box.

[0009] 2. The inner liner box and the multi-layer structure box made of honeycomb paperboard greatly improve the cushioning protection and molding pressure resistance of the packaging box. The desiccant filling and ventilation holes inside the box ensure the dryness inside the box and avoid damage to product quality due to moisture.

[0010] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0020] A packaging box, such as Figure 1-5 As shown, it includes an outer box body 10 and a drawer box 20, one end of the outer box body 10 is provided with an opening, the top of the drawer box 20 is provided with an opening, and the drawer box 20 is inserted into the outer box body 10, and a self-locking structure is provided between the outer box body 10 and the drawer box 20 for preventing the drawer box 20 from sliding out;

[0021] A notch 11 is provided at the middle position of the two side walls of the outer box body 10 near the opening end. The self-locking structure includes a fixed plate 12 and a limiting protrusion 21. The fixed plate 12 is connected to the notch 11. The limiting protrusion 21 is provided on the outer walls of the drawer box 20 on both sides and corresponds to the position of the fixed plate 12. An adsorption component is also provided between the fixed plate 12 and the limiting protrusion 21 to prevent the self-locking structure from loosening.

[0022] like Figure 2 As shown, the fixing plate 12 and the notch 11 are hinged to each other so that the fixing plate 12 can be folded outwards. A hanging hole 13 is provided between the two sides of the fixing plate 12, and the hanging hole 13 is hung with the corresponding limiting protrusion 21 on the same side.
