Description

Technical Field

[0001] This utility model particularly relates to a flexible linkage packaging box. Background Technology

[0002] In the packaging of candy and other similar products, the opening is typically located at the top of the box and has a limited area. Current technologies generally employ either a single-axis flip-top or a sliding cover opening mechanism.

[0003] The single-axis flip cover uses a fixed pivot to make the lid flip outward along an arc trajectory. The flipping radius is limited by the thickness of the box, resulting in insufficient exposure of the opening for taking out items.

[0004] Sliding covers require slide rails to be installed on the side wall of the box, which occupies internal space, reduces the effective volume inside the box, and the exposed slide rails damage the overall appearance.

[0005] In addition, all of the above solutions require additional hinges, slide rails or fasteners, resulting in a large number of parts and complex assembly, making it difficult to meet the needs of low-cost, highly automated production. Utility Model Content

[0053] Furthermore, the first connecting part 2, the second connecting part 3, and the fixed connecting part 4 are all made of plastic.

[0054] The working principle of this utility model is as follows:

[0055] As an example, this application uses a cuboid box 1 as an example to specifically illustrate its structural design and working principle. An inwardly recessed opening 12 is formed on the end face of the box 1, and an internal cavity 11 is formed inside the box 1 for storing items (such as candy, pills, etc.). A movable groove 13 is formed on the end face of the box 1 to guide the movement trajectory of the first connecting part 2. The fixed connecting part 4 is fixed to the mounting hole on the box 1 by an interference fit with the positioning boss 41 to ensure structural stability. The first connecting part 2 is rotatably connected to the fixed connecting part 4. The principle of rotation is that a second notch 34 is provided at the connection between the fixed connecting part 4 and the first connecting part 2. A second elastic deformation part 35 is formed at the bottom of the second notch 34, allowing the first connecting part 2 to fold relative to the fixed connecting part 4. A first notch 32 is provided at the connection between the first connecting part 2 and the second connecting part 3, and a first elastic deformation part 33 is formed at the bottom of the first notch 32, allowing the first connecting part 2 to fold relative to the second connecting part 3.

[0056] Work process

[0057] Closed state: The second connecting part 3 covers the retrieval port, the first elastic deformation part 33 and the second elastic deformation part 35 are both in a natural state without elastic deformation, and the annular sealing flange 36 of the second connecting part 3 is tightly fitted with the retrieval port.

[0058] Opening process: Press the first connecting part 2, so that it folds into the movable groove 13 relative to the fixed connecting part 4 through the second elastic deformation part 35; the movement of the first connecting part 2 is transmitted to the second connecting part 3 through the first elastic deformation part 33, so that the second connecting part 3 moves into the movable groove 13 and folds upward, and finally the second connecting part 3 leaves to fully expose the retrieval opening (at this time, one side of the second connecting part 3 abuts against the groove edge of the movable groove 13).

[0059] Reset process:

[0060] Push the second connecting part 3 to cover the retrieval opening 12 again. Then, the second connecting part 3, through the first elastic deformation part 33, links with the first connecting part 2. Under the action of the second elastic deformation part 35, the outer contours of the first connecting part 2, the second connecting part 3, and the fixed connecting part 4 can together form a continuous flat surface, such as... Figure 6 As shown.

[0061] In the above technical solution, different shaped notches, such as triangles, U-shapes, arcs, etc., can be used to achieve elastic folding, and the fixed connection part 4 can also be fixed to the box body 1 by means of buckles, etc.

[0062] Based on the above technical solution, the first connecting part 2 is provided with a guide part 23. When the first connecting part 2 is pressed, the guide part 23 slides into the opening of the movable groove 13 and is continuously limited by the two side walls of the movable groove 13 to ensure that the first connecting part 2 moves along a preset path (such as the first connecting part 2 driving the second connecting part 3 to fold).

[0063] Based on the above technical solution, a decorative window 14 is provided on the box body 1, and the decorative window 14 is connected to the movable groove 13; during the movement of the first connecting part 2, the decorative window 14 exposes at least part of the structure of the guide part 23. The decorative window 14 is an irregular through-hole opened in the side wall of the box body 1, and its outline is geometric. Through the cooperation of the guide part 23 and the decorative window 14, the line design can be revealed while the internal space is completely covered.

[0064] Based on the above technical solution, when the packaging box is closed: the outer contours of the first connecting part 2, the first connecting part 3 and the fixed connecting part 4 together form a continuous flat surface; the flat surface is flush with the end face 16 of the box body 1, further enhancing the high-end texture and visual minimalism.

[0065] Based on the above technical solution, as Embodiment 2, Embodiment 2 optimizes the shape of the decorative window 14. By simplifying the outline lines and adjusting the proportional relationships, it achieves a more concise and aesthetically pleasing visual effect while meeting functional requirements. It should be noted that this utility model does not limit the specific shape of the decorative window 14. Various shape changes or equivalent substitutions made by those skilled in the art to the decorative window 14 under the guidance of the technical solution of this utility model should be included within the protection scope of this utility model.

[0066] This invention utilizes a combined motion of "the first connecting part moving within the movable groove + the second connecting part simultaneously flipping" to fully expose the retrieval opening, making it more convenient to use. Furthermore, the first and second connecting parts fold together via a first elastic deformation part, eliminating the need for hinges, slide rails, or fasteners, thus reducing the number of parts and improving assembly efficiency.

[0067] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
