Please refer to FIG. 1 to FIG. 7 together, and now the lid-type capsule structure provided by the embodiment of the present application will be described. The lid-type capsule structure provided in the embodiment of the present application includes a capsule body 1 , a container lid 2 and a top lid structure 3 . The capsule body 1 is used to pre-seal the beverage ingredients 8. The capsule body 1 includes a capsule shell 11 and a sealing cover 12. The bottom of the capsule shell 11 is open, and the sealing cover 12 can be opened and closed in the bottom opening 17 of the capsule shell 11. superior. 3 and 11 at the same time, the capsule shell 11 is connected to the inner wall of the container cover 2 , and during use, the capsule shell 11 containing the beverage ingredients 8 can be placed in the water storage container 4 through the container cover 2 . Referring to FIGS. 1 , 3 and 5 , the top cover structure 3 is used to penetrate into the capsule shell 11 and open the sealing cover 12 toward the outside of the capsule shell 11 , so that the bottom opening 17 of the capsule shell 11 is opened. Then, when the user needs to drink beverages, the top of the capsule shell 11 can be pierced through the top cover structure 3, so that one end of the top cover structure 3 can be inserted into the capsule shell 11 or the top cover structure 3 can be placed inside the capsule shell 11. . Further referring to FIG. 9 , under the action of external force, after the end of the top cover structure 3 protruding into the capsule shell 11 passes through the beverage ingredients 8, the sealing cover 12 can be pushed open toward the outside of the capsule shell 11, and the capsule shell can be opened. Bottom opening 17 of 11. The beverage ingredients 8 pre-sealed in the capsule shell 11 can be quickly and cleanly dropped into the water storage container 4 through the bottom opening 17 of the capsule shell 11 due to the action of its own gravity, and the beverage ingredients 8 and the water storage container 4 can be separated. After shaking and mixing the water in it, you can get a delicious drink that you can drink directly.

Compared with the prior art, the lid-type capsule structure provided by the present application is provided with a container cover 2, a capsule shell 11 connected to the inner wall of the container cover 2, and a top cover structure 3 for piercing the capsule shell 11. Then, when the user needs to drink the beverage, he only needs to place the capsule shell 11 containing the beverage ingredients 8 in the water storage container 4 through the container cover 2, and then pierce the bottle cap and the top of the capsule shell 11 through one end of the top cover structure 3. Then, the end of the top cover structure 3 extending into the capsule shell 11 is used to push the sealing cover 12 toward the outside of the capsule shell 11, so that the bottom opening 17 of the capsule shell 11 can be opened. In this way, the beverage ingredients 8 pre-sealed in the capsule shell 11 can be quickly and cleanly dropped into the water storage container 4 through the bottom opening 17 of the capsule shell 11, which is convenient and quick to operate. In addition, because the beverage ingredients 8 pre-sealed in the capsule shell 11 directly fall into the water storage container 4 through the bottom opening 17 of the capsule shell 11, there is no need to pierce the bottom of the capsule shell 11, which effectively solves the problem of piercing the capsule shell 11. There is a problem that the debris or impurities existing in the water storage container 4 will fall into the water storage container 4 with the beverage ingredients 8, so that the beverage in the water storage container 4 will not be polluted, and the cleanliness and hygiene of the beverage prepared in the water storage container 4 will be fully guaranteed. health and safety.

It can be understood that in another embodiment of the present application, referring to FIGS. 6 and 7 , the top cover structure 3 can also be arranged in the capsule shell 11 , and one end of the top cover structure 3 can open the sealing cover toward the outside of the capsule shell 11 12. The container cover 2 is provided with a pressing structure that can apply an external force to the other end of the top cover structure 3. Through the pressing structure, one end of the top cover structure 3 can be pushed to the outside of the capsule shell 11 to open the sealing cover 12.

In another embodiment of the present application, please refer to FIG. 6 , the pressing structure may be that the top side wall of the container cover 2 is made of the first flexible soft rubber piece 5 that can be pressed, and the top of the capsule shell 11 is made of a pressable soft rubber piece 5 . The second flexible soft glue piece 9 is made, and then the other end of the top cover structure 3 is connected to the second flexible soft glue piece 9 at the top of the capsule shell 11 , then the first flexible soft glue piece on the top side wall of the container cover 2 can be pressed 5, the first flexible soft piece 5 exerts pressure on the second flexible soft piece 9 on the top of the capsule shell 11, and the second flexible soft piece 9 presses the top of the top cover structure 3 to realize the bottom end of the top cover structure 3 Opening of the sealing cover 12 towards the outside of the capsule shell 11 enables the bottom opening 17 of the capsule shell 11 to be opened.

In another embodiment of the present application, please refer to FIG. 7 , the pressing structure may also be that a through hole 21 is provided on the container cover 2 , and a second flexible soft rubber piece 9 is encapsulated in the through hole 21 of the container cover 2 , and the top of the capsule shell 11 is also provided with a top opening, and the top opening of the capsule shell 11 and the through hole 21 of the container cover 2 form the top opening 18 of the capsule shell 11 . In this way, it is only necessary to connect the top end of the top cover structure 3 with the second flexible soft rubber piece 9 , then the top end of the top cover structure 3 can be pressed by pressing the second flexible soft rubber piece 9 at the top opening of the capsule shell 11 . , to realize that the bottom end of the top cover structure 3 faces the outside of the capsule shell 11 to open the sealing cover 12 , so that the bottom opening 17 of the capsule shell 11 is opened.
