Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to an anti-loosening packaging box. Background Technology

[0002] In the field of tea packaging, the storage quality of tea places high demands on the airtightness and structural stability of packaging containers. Currently, traditional tea packaging boxes often employ a threaded connection between the lid and the box body. However, this threaded connection is susceptible to loosening due to external factors such as vibration, resulting in insufficient structural stability and poor sealing performance. If used for tea packaging, this makes the tea highly susceptible to moisture absorption and flavor transfer, severely impacting its quality and failing to meet the practical requirements of tea storage. Therefore, there is an urgent need to develop a tea box with a stable structure and excellent sealing performance to overcome the shortcomings of existing technologies. Summary of the Invention

[0003] This utility model provides an anti-loosening packaging box to overcome the defects of existing tea boxes, such as poor sealing, inconvenient opening and closing, and insufficient structural stability.

[0004] The present invention adopts the following technical solution: An anti-loosening packaging box includes a box body with an open-top cavity, a top cover, and a collar. The top cover has an outer peripheral wall that fits onto the outer side of the upper end of the box body. The outer peripheral wall of the upper end of the box body has at least two protrusions. The inner side of the outer peripheral wall has a guide groove corresponding to the protrusions. One side of the bottom of the guide groove has a communicating slot. The protrusions are inserted into the slot. The slot opening has a protrusion to prevent the protrusions from disengaging from the slot. The collar is fitted onto the outer side of the top cover and has an elastic force that returns to its center, causing the top cover to fit tightly against the base.

[0005] Furthermore, the outer wall of the aforementioned top cover is provided with several limiting grooves, and the inner wall of the aforementioned collar is provided with guide posts that cooperate with the limiting grooves.

[0006] Furthermore, the outer wall of the aforementioned ring is an inwardly inclined slope structure.

[0007] Furthermore, the aforementioned protrusion has a hemispherical structure.

[0008] Furthermore, the upper end of the aforementioned collar is provided with a raised edge extending toward its center, the diameter of which is smaller than the diameter of the aforementioned upper cover.

[0009] Furthermore, the outer wall at the upper end of the box has four protruding ribs, which are symmetrically distributed circumferentially.

[0010] Furthermore, both the outer wall of the aforementioned top cover and the inner wall of the aforementioned collar have a frosted surface.

[0011] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. The beveled design of the outer wall of the ring of this utility model, combined with its own elasticity, can make the top cover and the base fit tightly during assembly, effectively improving the sealing effect of the tea box, preventing the tea from getting damp and tasting due to poor sealing, and ensuring the quality of tea storage.

[0012] 2. The packaging box of this utility model forms a multi-positioning structure by cooperating the protrusion on the collar with the limiting groove on the top cover and the base, and by engaging the top cover slot with the base protrusion. This makes the components firmly connected, effectively prevents the structure from loosening due to external factors such as vibration, and significantly improves the overall structural stability.

[0013] 3. The guide groove and protrusion of the top cover of this utility model can achieve precise positioning and guidance during the opening and closing process, making the operation smooth and convenient. Compared with the traditional threaded connection packaging box, it does not require frequent twisting, and the user experience is greatly improved. Attached Figure Description

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] Reference Figures 1-7An anti-loosening packaging box includes a box body 1, which has an open cavity 10 inside. The box body 1 is circular, and the cavity 10 is used to place materials. It also includes a top cover 2 and a collar 3. The top cover 2 has an outer peripheral wall 21 that fits onto the outer side of the upper end of the box body 1, covering the opening of the cavity 10. The outer peripheral wall 21 fits onto the outer side of the upper end of the box body 1. At least two protrusions 11 are provided on the outer wall of the upper end of the box body 1. A guide groove 23 corresponding to the protrusions 11 is provided on the inner side of the outer peripheral wall 21. A connecting slot 22 is provided on one side of the bottom of the guide groove 23. The protrusions 11 are inserted into the slot 22. A protrusion 231 is provided at the opening of the slot 22 to prevent the protrusions 11 from disengaging from the slot 22. The protrusion 231 is located between the slot 22 and the guide groove 23. The collar 3 is fitted onto the outside of the upper cover 2. The collar 3 has an elastic force that returns to its center, which makes the upper cover 2 fit tightly against the base.

[0023] Reference Figure 4 The outer wall of the upper cover 2 is provided with several limiting grooves 20, and the inner wall of the collar 3 is provided with guide post 32 that cooperates with the limiting groove 20. The guide post 32 cooperates with the limiting groove 20 so that the upper cover 2 can be quickly aligned with the collar 3.

[0024] Reference Figure 3 , Figure 6 The outer wall of the aforementioned collar 3 is an inwardly inclined slope structure, that is, the outer diameter of the collar 3 gradually decreases from top to bottom, and the cross-section of the collar 3 is L-shaped. When the collar 3 is fitted onto the outside of the upper cover 2, the slope structure gives the collar 3 an elastic force that restores its deformation towards its center, causing the upper cover 2 to fit tightly against the base.

[0025] Reference Figure 7 The protrusion 231 is hemispherical in shape. The protrusion 231 can prevent the protrusion 11 from disengaging from the slot 22. The outer wall of the protrusion 231 is smooth and does not affect the protrusion 11 from being obliquely inserted into the slot 22 by the guide groove 23.

[0026] Reference Figure 4 The upper end of the aforementioned collar 3 is provided with a protruding edge 31 extending toward its center. The diameter of the protruding edge 31 is smaller than the diameter of the aforementioned upper cover 2, making it difficult for the upper cover 2 to detach from the collar 3 from the inside of the protruding edge 31.

[0027] The outer wall of the upper end of the box 1 is provided with four protrusions 11, which are symmetrically distributed in the circumferential direction.

[0028] Both the outer wall of the top cover 2 and the inner wall of the collar 3 are frosted. The friction between the outer wall of the top cover 2 and the inner wall of the collar 3 is large, making it less susceptible to loosening due to vibration, and the connection is more secure and stable.

[0029] During packaging, the top cover 2 is fitted onto the top of the box body 1, the protrusion 11 is inserted into the guide groove 23, and then the top cover 2 is rotated. The protrusion 11 slides obliquely upward from the guide groove 23 into the slot 22. The outer side of the top cover 2 is fitted with the collar 3. The shrinkage elasticity of the collar 3 restores its deformation and makes the top cover 2 fit tightly with the base.

[0030] In addition, this packaging box is not limited to packaging tea; it can also be used to package biscuits, medicinal herbs, etc.

[0031] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
