[0002] With the improvement of living standards, the demand for brewing beverage capsules is also increasing. The cap-type capsule structure is one of the brewing beverage capsules. Generally, the beverage ingredients to be brewed are pre-sealed in the capsule first. When the user needs to drink the beverage, the capsule is punctured and opened, and the beverage ingredients sealed in the capsule are poured into a bottle. After the beverage ingredients are mixed with the water in the bottle, a delicious beverage that can be directly drunk can be obtained.

[0003] However, the current cap-type capsule structure generally relies on manual pressure to puncture, and the puncture opening is usually small, resulting in that the beverage ingredients sealed in the capsule are generally difficult to be quickly and cleanly poured into the bottle, which is easy to cause waste. Moreover, when manually pressing to puncture, debris is generally generated at the puncture opening. When the beverage ingredients are poured into the bottle from the small puncture opening, the puncture opening is squeezed by the beverage ingredients, causing the debris at the puncture opening to easily fall into the bottle. When the user drinks, the debris will enter the human body and endanger health. Summary of the Invention

[0072] Please refer to Figures 1 to 7 for an explanation of the lid-type capsule structure provided by the embodiments of the present application. The lid-type capsule structure provided by the embodiments 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 lid 12. The bottom of the capsule shell 11 is open, and the sealing lid 12 is sealingly and openably encapsulated on the bottom opening 17 of the capsule shell 11. Also refer to Figure 3 and Figure 11 . The capsule shell 11 is connected to the inner wall of the container lid 2. Then, during use, the capsule shell 11 containing the beverage ingredients 8 can be placed in the water storage container 4 through the container lid 2. Refer to Figure 1 , Figure 3 and Figure 5 . The top lid structure 3 is used to pierce into the capsule shell 11 and push the sealing lid 12 outward toward the outside of the capsule shell 11 to open the bottom opening 17 of the capsule shell 11. Then, when the user needs to drink the beverage, the top of the capsule shell 11 can be punctured through the top lid structure 3 so that one end of the top lid structure 3 extends into the capsule shell 11 or the top lid structure 3 is placed inside the capsule shell 11. Further refer to Figure 9 . Under the action of an external force, after the end of the top lid structure 3 extending into the capsule shell 11 passes through the beverage ingredients 8, the sealing lid 12 can be pushed outward toward the outside of the capsule shell 11, and then the bottom opening 17 of the capsule shell 11 can be opened. The beverage ingredients 8 pre-sealed in the capsule shell 11, due to their own gravity, can quickly and cleanly fall into the water storage container 4 through the bottom opening 17 of the capsule shell 11. After shaking and mixing the beverage ingredients 8 with the water in the water storage container 4, a delicious beverage ready to drink can be obtained.

[0073] The cover-type capsule structure provided by the present application, compared with the prior art, 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 puncturing the capsule shell 11. When a user needs to drink a beverage, only by placing the capsule shell 11 containing the beverage ingredients 8 in the water storage container 4 through the container cover 2, and then puncturing the top of the bottle cap and the capsule shell 11 through one end of the top cover structure 3, and then using the end of the top cover structure 3 extending into the capsule shell 11 to push the sealing cover 12 towards the outside of the capsule shell 11, 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 quickly and cleanly fall into the water storage container 4 through the bottom opening 17 of the capsule shell 11, and the operation is convenient and fast. Moreover, since 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 without puncturing the bottom of the capsule shell 11, the problem that debris or impurities at the puncture of the capsule shell 11 will fall into the water storage container 4 along with the beverage ingredients 8 is effectively solved, so that the beverage in the water storage container 4 will not be contaminated, and the cleanliness, hygiene, health and safety of the beverage prepared in the water storage container 4 are fully guaranteed.

[0074] It can be understood that in another embodiment of the present application, please refer to Figure 6 and Figure 7 , the top cover structure 3 can also be arranged in the capsule shell 11. One end of the top cover structure 3 can push the sealing cover 12 towards the outside of the capsule shell 11. The container cover 2 is provided with a pressing structure for applying 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 is pushed towards the outside of the capsule shell 11 to open the sealing cover 12.

[0075] In another embodiment of the present application, please refer to Figure 6 , the pressing structure can be made of a first flexible soft rubber member 5 that can be pressed on the top side wall of the container cover 2, and the top of the capsule shell 11 is made of a second flexible soft rubber member 9 that can be pressed. Then, the other end of the top cover structure 3 is connected to the second flexible soft rubber member 9 at the top of the capsule shell 11. By pressing the first flexible soft rubber member 5 on the top side wall of the container cover 2, the first flexible soft rubber member 5 applies pressure to the second flexible soft rubber member 9 at the top of the capsule shell 11, and the second flexible soft rubber member 9 presses the top end of the top cover structure 3, so that the bottom end of the top cover structure 3 is pushed towards the outside of the capsule shell 11 to open the sealing cover 12 and open the bottom opening 17 of the capsule shell 11.

[0076] In another embodiment of the present application, please refer to Figure 7, the pressing structure can also be that a through hole 21 is provided on the container lid 2, and a second flexible rubber part 9 is encapsulated in the through hole 21 of the container lid 2, and the top end of the capsule shell 11 is also provided with a top opening. The top opening of the capsule shell 11 and the through hole 21 of the container lid 2 form the top open end 18 of the capsule shell 11. In this way, only by connecting the top end of the top cover structure 3 to the second flexible rubber part 9, the second flexible rubber part 9 at the top opening of the capsule shell 11 can be pressed to apply pressure to the top end of the top cover structure 3, so that the bottom end of the top cover structure 3 opens the sealing cover 12 towards the outside of the capsule shell 11, and the bottom open end 17 of the capsule shell 11 is opened.

[0077] In another embodiment of the present application, please refer to Figure 10 , the capsule body 1 further includes a first sealing film 13 encapsulated on the bottom open end 17 of the capsule shell 11, and the first sealing film 13 covers the side of the sealing cover 12 facing away from the capsule shell 11.

[0078] In this embodiment, by encapsulating a first sealing film 13 on the bottom open end 17 of the capsule shell 11 and covering the first sealing film 13 on the side of the sealing cover 12 facing away from the capsule shell 11. When the capsule shell 11 seals the beverage ingredient 8, the bottom open end 17 of the capsule shell 11 is first sealed by the sealing cover 12, and then the bottom open end 17 of the capsule shell 11 is secondarily sealed by the first sealing film 13 covering the outside of the sealing cover 12, enhancing the sealing performance of the capsule shell 11, preventing the powdered beverage ingredient 8 from getting damp during the process of carrying and transporting, or preventing the liquid concentrated beverage ingredient 8 from leaking during the process of carrying and transporting. Moreover, by covering the first sealing film 13 on the side of the sealing cover 12 facing away from the capsule shell 11, the first sealing film 13 can also play an anti-theft role, preventing the sealing cover 12 of the capsule shell 11 from being opened before sale. When drinking, the sealing cover 12 can be pushed open towards the outside of the capsule shell 11 by one end of the top cover structure 3. When the sealing cover 12 is opened outwards, the part connecting the first sealing film 13 and the bottom open end 17 of the capsule shell 11 will be torn off, so as to open the bottom open end 17 of the capsule shell 11. In this way, it is not necessary to pierce the first sealing film 13 on the bottom open end 17 of the capsule shell 11, effectively avoiding the debris or impurities at the piercing point from falling into the water storage container 4 along with the beverage ingredient 8, thus not polluting the beverage in the water storage container 4, and fully ensuring the cleanliness, hygiene, health and safety of the beverage prepared in the water storage container 4.

[0079] Understandably, in another embodiment of the present application, the beverage ingredients 8 sealed in the capsule body 1 include, but are not limited to, powdered beverage ingredients 8 or concentrated liquid beverage ingredients 8. The first sealing film 13 can be a polypropylene film, an aluminum foil film, or a composite of an aluminum foil and a polypropylene film stack. The first sealing film 13 has properties such as light impermeability and air impermeability. The thickness of the first sealing film 13 ranges from 25 μm to 35 μm, and the bottom opening 17 of the capsule shell 11 is sealed via hot pressing, adhesion, or other bonding methods. Of course, the thickness of the first sealing film 13 can be reasonably set according to actual usage requirements and is not uniquely limited herein.

[0080] In another embodiment of the present application, the first sealing film 13 is pasted on the side of the sealing cover 12 facing away from the capsule shell 11. In this embodiment, when the first sealing film 13 is pasted on the side of the sealing cover 12 facing away from the capsule shell 11, when the sealing cover 12 is opened, the first sealing film 13 is tightly adhered to the sealing cover 12, preventing the torn first sealing film 13 from falling into the water storage container 4 and further avoiding debris from falling into the water storage container 4, ensuring the health and hygiene of the beverage in the water storage container 4.

[0081] Understandably, in another embodiment of the present application, both the sealing cover 12 and the first sealing film 13 are encapsulated on the bottom opening 17 of the capsule shell 11 by a high-temperature welding process, playing a good sealing role and preventing the beverage ingredients 8 in the capsule shell 11 from coming into contact with external air and getting damp or contaminated. The first sealing film 13 can be fused to the side of the sealing cover 12 facing away from the capsule shell 11 by a high-temperature welding process, or can be adhered to the side of the sealing cover 12 facing away from the capsule shell 11 with a food-grade adhesive, which is not uniquely limited herein.

[0082] In another embodiment of the present application, please refer to Figure 8 and Figure 10 , the capsule body 1 further includes a reinforcement member that connects the sealing cover 12 to the capsule shell 11. In this embodiment, by providing a reinforcement member that connects the sealing cover 12 to the capsule shell 11, the stability of the connection between the sealing cover 12 and the bottom opening 17 of the capsule shell 11 is enhanced, preventing the sealing cover 12 from being opened due to the gravity of the beverage ingredients 8 or during carrying and transportation before the capsule shell 11 is sold. And, understandably, the reinforcement member in this embodiment only strengthens the stability of the connection between the sealing cover 12 and the bottom opening 17 of the capsule shell 11, and it can be made of a material that can be torn when the external force exceeds the tension that the reinforcement member can withstand, so that when one end of the top cover structure 3 pushes the sealing cover 12 towards the outside of the capsule shell 11, the bottom opening 17 of the capsule shell 11 can be easily opened.

[0083] In another embodiment of the present application, please refer to Figure 8 and Figure 10, the reinforcement member includes a first connecting piece 14 for restricting the sealing cover 12 to the capsule shell 11, and the first connecting piece 14 is respectively connected to the sealing cover 12 and the capsule shell 11.

[0084] In this embodiment, the reinforcement member includes a first connecting piece 14 for restricting the sealing cover 12 to the capsule shell 11. The sealing cover 12 is connected to the capsule shell 11 through the first connecting piece 14, enhancing the stability of the connection of the sealing cover 12 to the bottom opening 17 of the capsule shell 11. Moreover, when one end of the top cover structure 3 pushes the sealing cover 12 outwards towards the outside of the capsule shell 11, due to the restricting effect of the first connecting piece 14 on the sealing cover 12, the sealing cover 12 opens the bottom opening 17 of the capsule shell 11 like a door leaf, and the opened sealing cover 12 is restricted to the capsule shell 11 through the first connecting piece 14 and will not fall into the water storage container 4, ensuring the health and hygiene of the beverage in the water storage container 4.

[0085] In another embodiment of the present application, please refer to Figure 8 and Figure 10 , the reinforcement member further includes a plurality of second connecting pieces 15. The plurality of second connecting pieces 15 are spaced apart along the circumferential direction of the capsule shell 11. Each second connecting piece 15 is respectively connected to the sealing cover 12 and the capsule shell 11, and the width of each second connecting piece 15 is smaller than the width of the first connecting piece 14.

[0086] In this embodiment, the reinforcement member further includes a plurality of second connecting pieces 15. The plurality of second connecting pieces 15 are spaced apart along the circumferential direction of the capsule shell 11. The sealing cover 12 is respectively connected to the capsule shell 11 through the second connecting pieces 15, further enhancing the stability of the connection of the sealing cover 12 to the bottom opening 17 of the capsule shell 11. Moreover, the width of each second connecting piece 15 is smaller than the width of the first connecting piece 14, so that each second connecting piece 15 is in a relatively weak connection relative to the first connecting piece 14. When one end of the top cover structure 3 pushes the sealing cover 12 outwards towards the outside of the capsule shell 11, each second connecting piece 15 is torn off while the first connecting piece 14 only bends and does not break, so that the opened sealing cover 12 is restricted to the capsule shell 11 through the first connecting piece 14 and will not fall into the water storage container 4, ensuring the health and hygiene of the beverage in the water storage container 4.

[0087] It can be understood that, in another embodiment of the present application, the first connecting piece 14 can be a soft film or soft rubber strip that can be torn off and is easily bendable, so that when the sealing cover 12 is not pushed open, the first connecting piece 14 can strengthen the stability of the connection of the sealing cover 12 to the bottom opening 17 of the capsule shell 11, and when the sealing cover 12 is pushed open, it will not hinder or interfere with the sealing cover 12, ensuring the smooth opening of the bottom opening 17 of the capsule shell 11. It can be understood that, in another embodiment, the first connecting piece 14 can also be a bendable metal sheet or metal strip such as copper or aluminum.
