[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0016] like Figure 1-3 As shown, the present invention provides a cup lid with a tea-filtering function, comprising a cup lid body 1, a sealing component 2, and a top cover 3. The specific structure and assembly relationship of each component are as follows: The cup lid body 1 of this utility model consists of a plastic lid 101 and a steel ring 102. The plastic lid 101 is made of food-grade PP material and has a stepped hollow cylindrical structure with a smaller upper dimension than lower dimension. This structure can accommodate container openings of different diameters and enhances the overall stability of the lid. Both the upper and lower inner walls of the plastic lid 101 are machined with internal threads, and an annular protrusion 1011 extends downwards from the upper part, forming an annular groove 1012 between the annular protrusion 1011 and the lower inner wall of the plastic lid 101, providing positioning space for the installation of the sealing component 2. A filter slot 1013 is also provided at the bottom of the upper part of the plastic lid 101 for fixing the filter 205. The steel ring 102 is made of 304 stainless steel, and its inner diameter is adapted to the outer diameter of the lower part of the plastic lid 101. It is fitted onto the outer side of the lower part of the plastic lid 101 by interference fit. This design can enhance the structural strength of the lower part of the plastic lid 101 and avoid lid deformation due to long-term use. On the other hand, it can improve the texture and wear resistance of the lid and extend its service life. The sealing component 2 in this utility model is the core functional component of the cup lid, including an inner plug body 201, an inner plug end cap 202, an inner plug silicone ring 203, and a sealing silicone gasket 206. Each component is installed sequentially in the inner cavity of the plastic lid body 101, and the specific assembly method is as follows: The inner stopper 202 is made of food-grade ABS material. Its outer side is machined with external threads that match the internal threads on the upper part of the plastic cap 101. It is fixed to the upper interior of the plastic cap 101 via a threaded connection, allowing for detachable installation and easy cleaning and replacement. The lower end of the inner stopper 202 has an annular groove into which the inner silicone ring 203 (made of food-grade silicone with a hardness of 50±5 Shore A) is embedded. When the cup cap is connected to the container body 4, the inner silicone ring 203 can tightly fit the opening end of the container body 4, achieving a primary seal and preventing liquid leakage. The plastic cover 101 also has an annular groove on the upper outer side and middle side, into which the anti-slip rubber ring 204 (made of the same material as the inner silicone ring 203) is embedded to cooperate with the top cover 3 to achieve a secondary seal. The inner plug end cap 202 is made of food-grade PP material. It has an elastic buckle at the lower end and a buckle groove at the upper end of the inner plug body 201. The inner plug end cap 202 is fixed to the upper end of the inner plug body 201 by the snap-fit ​​between the buckle and the buckle groove. It can block the internal channel of the inner plug body 201, further improve the sealing effect, and facilitate the addition of tea leaves after disassembly. The filter screen 205 is made of 304 stainless steel with a mesh size of 0.5-1mm, which can effectively filter tea leaves. The filter screen 205 is placed in the filter screen slot 1013 at the bottom of the upper part of the plastic cover 101. The depth of the filter screen slot 1013 is adapted to the thickness of the filter screen 205 to ensure that the filter screen does not shift after installation. The sealing silicone gasket 206 is made of food-grade silicone and is designed as a grooved structure with an outer edge. Its sidewalls and edges are embedded in the annular groove 1012 at the bottom of the plastic cap 101, and its bottom is tightly fitted with the filter screen 205 to achieve a three-level seal. The thickness of the middle part of the bottom of the sealing silicone gasket 206 is 0.3-0.5mm (less than the 1-1.2mm of other parts), and this middle part is connected to other parts by an easy-tear line, which can be removed according to usage needs: when the container is used to store alcoholic beverages, the middle part is not removed, and the sealing silicone gasket 206 can completely seal the filter screen to prevent the alcoholic beverages from contacting the filter screen; when the container is used to brew tea, the middle part is removed, and the liquid can pass through the filter screen for filtration. The top cover 3 of this invention is made of food-grade PP material and has a double-layer anti-scalding structure in a circular shape. Its inner wall has an annular groove that matches the anti-slip rubber ring 204. The top cover 3 is installed on top of the cup lid body 1 by snapping it on. The anti-slip rubber ring 204 is embedded in the annular groove of the top cover 3 to achieve a tight fit. This makes it easy to install and remove, and can be used as a small teacup. It also prevents external dust from entering the inside of the cup lid, while improving the overall sealing performance. The beverage packaging container that can be used as a teacup as described in this embodiment, such as Figure 4As shown, the cup lid with the tea-filtering function and the container body 4 have the following specific structure: The container body 4 is made of high borosilicate glass and is sintered at high temperature to form a double-walled cup structure. A vacuum layer exists between the two layers, providing insulation (keeping liquids above 60℃ for 4-6 hours) and scalding protection. High borosilicate glass also exhibits excellent chemical stability, being resistant to acids and alkalis, making it suitable for storing alcoholic beverages and brewing tea. The upper opening of the container body 4 has external threads that mate with the internal threads on the lower part of the lid body 1. The lid is securely attached to the container body 4 via these threads, ensuring a strong connection and easy disassembly. How to use When used as a beverage packaging container: Pour the beverage into the container body 4, leaving the middle part of the sealing silicone gasket 206 intact (do not remove it), and put on the lid (the lid body 1 is threaded to the container body 4, and the top cover 3 is fastened to the lid body 1). At this time, the inner silicone ring 203, the sealing silicone gasket 206, and the anti-slip rubber ring 204 form a triple seal, which can effectively prevent the beverage from leaking and facilitate storage and carrying. When drinking, simply unscrew the lid to drink directly. When using it as a teacup: unscrew the lid, remove the inner stopper body 201, add tea leaves into the space between the inner stopper cap 202 and the filter screen 205, and then reinstall the inner stopper body 201; tear off the middle part of the bottom of the sealing silicone gasket 206, and thread the lid to the container body 4; pour hot water into the container body 4, and the hot water enters the filter area through the middle opening of the sealing silicone gasket 206, comes into contact with the tea leaves and soaks them. After soaking, invert the container, and the tea water flows into the lower part of the container body 4 after being filtered through the filter screen, and can then be drunk, achieving "tea and water separation" and avoiding the inhalation of tea leaves when drinking. The tea-filtering cup lid of this embodiment achieves efficient sealing through a multi-layer sealing structure (inner silicone ring, sealing silicone pad, and anti-slip adhesive ring). Simultaneously, the filter screen, in conjunction with the removable sealing silicone pad, allows for flexible switching between "sealed storage" and "tea filtering" functions. The beverage packaging container using this lid employs a double-layer high borosilicate glass structure, combining heat insulation, heat protection, and chemical stability. It can function as both a "beverage packaging" and a "tea cup," enhancing the container's practicality and resource utilization, making it suitable for various scenarios such as home, office, and outdoor use.
