Description

Technical Field

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

[0002] Packaging boxes are a kind of daily necessities commonly used in life. They can be used to package food, cosmetics, stationery, electronic products, etc. China's packaging industry has experienced a period of rapid development and has become one of the largest packaging markets in the world. Market size forecast: It is expected that the market size of China's packaging industry will reach US$203.6 billion by 2024, and it is expected to reach US$262.61 billion by 2029. In addition, the improvement of environmental awareness has led to an increase in consumers' requirements for the environmental friendliness and sustainability of packaging materials, prompting the packaging box industry to innovate in material selection, production process and recycling. Among them, packaging structure design is an important link to ensure that products are safe, convenient and attractive to consumers during transportation, storage and sales.

[0003] It is a common problem that existing packaging boxes take up too much space. That is, they cannot be deformed after they are made. Regardless of whether there are items inside, they will take up a certain amount of space, resulting in space waste and increasing storage and transportation costs. Foldable packaging boxes, due to their environmental protection, economy, functionality and innovation, have occupied an important position in the packaging industry and have shown strong development potential.

[0004] Referring to the utility model patent with application number CN200920130844.2, a foldable packaging box is disclosed, comprising a base plate, a pair of side plates mounted on the base plate, and a pair of fixing plates mounted on the base plate, the base plate comprising a first end plate, a bottom plate, and a second end plate connected in sequence, the pair of side plates are respectively mounted on opposite sides of the bottom plate, the fixing plates are respectively mounted on the side of the first and second end plates away from the bottom plate, the base plate, the side plates and the fixing plates can be folded in a plane, and when assembling the packaging box, the side plates are fixed to the base plate by the fixing plates. The packaging box can achieve a folding effect, thereby reducing the cost of storage and transportation. However, in actual use, the surrounding assembly process of the foldable packaging box is relatively inconvenient, especially the pasting assembly between the two side plates and the base plate, which is not only time-consuming, but also the effect after molding is usually poor (i.e., if the pasting position between the side plates and the base plate is improper, the side plates of the packaging box will be concave or convex, and the aesthetics is not good), which affects the user's experience.

[0005] Therefore, it is necessary to provide a technical solution to solve the above problems. Utility Model Content

[0039] The hard substrate 1 comprises a top plate 11, a first outer plate 12, a bottom plate 13 and a second outer plate 14 which are connected in sequence, and folds are formed at the connection points between any two of them;

[0040] The side enclosure assembly 2 is composed of at least three inner panels connected in sequence, and a fold is provided at the connection between two adjacent inner panels. The side enclosure assembly 2 is adhered to the first outer panel 12 or the bottom panel 13 or the second outer panel 14, and forms a hollow cylindrical frame with openings at both ends when it is stretched out; a supporting component 3 is provided on the hard base plate 1 to form a support inside the hollow cylindrical frame.

[0041] Compared with the prior art, the foldable packaging box involved in the utility model is different in that the present application combines the side panels used to form the side enclosure of the packaging box into a side enclosure assembly 2. In this way, when the packaging box is normally stored or transported, the hard base plate 1 can be fully flattened and the side enclosure assembly 2 can be folded to minimize the space occupied by the packaging box. For details, please refer to Figure 2 When the packaging box needs to contain items, the side enclosure components 2 only need to be opened and the hard base plate 1 is folded to surround the side enclosure components 2, so that the packaging box can be smoothly formed. During the folding process of the hard base plate 1, the supporting component 3 is placed inside the hollow columnar frame formed by the side enclosure components 2 to support the side enclosure components 2, thereby preventing the side enclosure components 2 from deflecting or swinging during use and affecting the use of the packaging box. For details, please refer to Figure 1 Compared with the prior art, the packaging box involved in the present application not only takes less time in the assembly process, but also has no concave or convex situation at each side panel, which makes the packaging box more beautiful after molding and improves the user experience.
