[0002] In today's fast-paced lifestyle, cold brew tea, as a novel way of brewing tea, has gained popularity among many consumers. However, existing cold brew tea products have a series of significant problems. Traditional cold brew tea usually packages tea leaves and water separately. When brewing, consumers need to manually open the water bottle and add the tea leaves, a process that is not only cumbersome but also makes it difficult to accurately control the amount of tea leaves used. Furthermore, carrying tea leaves separately is extremely inconvenient, greatly diminishing the user experience of cold brew tea.
[0003] To address some of the aforementioned issues, detachable tea infuser lids have been introduced to the market. These lids work by placing tea leaves inside the cap and using a threaded insert to pierce the bottom of the cap, thus mixing the tea leaves with water. However, existing detachable tea infuser lids still have significant drawbacks. After brewing, they cannot effectively contain the tea leaves, causing consumers to drink tea leaves that have flowed out with the water, severely impacting the tea-drinking experience. Furthermore, existing lids have relatively simple anti-theft measures, making it difficult to reliably protect the solutes inside the cap. Therefore, there is an urgent need for an improved threaded insert and its application in a detachable tea infuser lid with anti-theft features. Utility Model Content

[0054] Specifically:
[0055] like Figure 8-9As shown, in the above embodiment, preferably, the upper outer cover 11 and the upper inner cover 12 are coaxially arranged, and both the upper outer cover 11 and the upper inner cover 12 are provided with internal threads; the upper cover anti-theft ring 13 is annular, and multiple easily broken connecting bridges 14 are arranged in a ring between the upper cover anti-theft ring 13 and the bottom end of the upper outer cover 11; rotating the upper outer cover 11 in the opposite direction can destroy the connecting bridges 14 between the upper cover anti-theft ring 13 and the upper outer cover 11.
[0056] In this embodiment, by setting the anti-theft ring 13 on the upper cover, the tea solute in the lower cover cup 23 can be effectively prevented from being contaminated and damaged, ensuring that the product purchased by the consumer is original and has not been tampered with, thus ensuring the quality and safety of the product.
[0057] like Figure 10-12 As shown, in the above embodiment, preferably, the upper outer cover connecting part 21 has a cylindrical structure, and the outer surface of the upper outer cover connecting part 21 is provided with external threads; the upper outer cover 11 is screwed onto the upper outer cover connecting part 21, and the upper inner cover 12 is inserted into the upper outer cover connecting part 21.
[0058] In the above embodiment, preferably, the lower cover cup body 23 is cylindrical, and the portion of the lower cover cup body 23 near the bottom of the cup is inwardly tapered; the inner wall of the lower cover cup body 23 is provided with multiple insertion guide grooves 25 that cooperate with the insertion orientation pins 33 of the threaded insertion plug 3, and the multiple insertion guide grooves 25 extend along the axial direction of the lower cover cup body 23; the cooperation of the multiple insertion guide grooves 25 and the insertion orientation pins 33 can restrict the rotational movement of the threaded insertion plug 3 within the lower cover 2.
[0059] In the above embodiment, preferably, after the threaded plug 3 pierces the bottom of the lower cover cup 23 downwards, the threaded plug 3 is engaged in the lower cover 2 through multiple plug guide grooves 25 and plug directional locking posts 33.
[0060] In the above embodiments, preferably, the outer surfaces of both the upper outer cover 11 and the lower outer cover 22 are provided with longitudinal anti-slip textures.
[0061] In the above embodiments, preferably, to prevent the lower outer cover 22 from loosening from the bottle neck, multiple reverse rotation limiting buckles are also arranged around the inner wall of the lower outer cover 22. In this embodiment, the reverse rotation limiting buckle is a protrusion provided on the inner wall of the lower outer cover 22, one end of which has a ramp structure and the other end of which has a right-angled edge structure. By setting the ramp and the right-angled edge, the lower outer cover 22 can only be screwed onto the bottle neck in one direction. The reverse rotation limiting buckle in this embodiment can also adopt other existing forms.
[0062] In the above embodiments, preferably, the method of use in this embodiment is as follows:
[0063] 1) Hold the beverage bottle with your hand to ensure that the bottle is stable and observe whether the anti-theft ring 13 on the top of the bottle cap is intact. If it is intact, it means that the bottle cap has not been opened and the beverage inside the bottle and the tea solute in the lower lid cup 23 are in the original sealed state.
[0064] 2) Rotate the top cover 1 in the opposite direction. During the rotation, the rotation of the top cover 1 will destroy the connecting bridge 14 between the top cover anti-theft ring 13 and the top outer cover 11, causing the top cover anti-theft ring 13 to separate from the top outer cover 11.
[0065] 3) As the upper cover 1 continues to rotate in the opposite direction, the upper inner cover 12 of the upper cover 1 drives the threaded plug 3 to move downward. As the threaded plug 3 continues to move downward, the plug slanted opening 32 at its lower end will gradually approach the bottom of the cup of the lower cover cup 23 and pierce the bottom of the cup of the lower cover cup 23.
[0066] 4) When the bottom of the lower lid cup 23 is pierced, the tea solute stored in the lower lid cup 23 falls into the bottle and mixes with the water solute in the bottle.
[0067] 5) When you want to drink tea, rotate the top cover 1 to open it. At this time, because the threaded plug 3 is engaged in the bottom cover 2 by multiple plug guide grooves 25 and plug directional locking posts 33, the threaded plug 3 remains in the bottom cover 2 after the top cover 1 is separated from the threaded plug 3 and the bottom cover 2. During the drinking process, the tea flows out through multiple first filter holes 35 and second filter holes 34 of the threaded plug 3, thereby achieving effective filtration of the tea leaves and preventing consumers from drinking tea leaves that flow out with the water, thus improving the tea drinking experience.
[0068] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
