In order to facilitate understanding of the technical features, contents and advantages of the present invention and the effects that can be achieved, the present invention is hereby described in detail as follows with the accompanying drawings and in the form of embodiments. The drawings used therein are only for illustration and auxiliary description, and may not be the true proportions and precise configurations after the implementation of the present invention. Therefore, the proportions and configurations of the attached drawings should not be interpreted to limit the scope of rights of the present invention in actual implementation.

All terms (including technical and scientific terms) used herein have the meanings commonly understood by those of ordinary skill in the art to which the present invention belongs. It will be further understood that those terms as defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meanings in the context of the relevant art and the present invention, and will not be interpreted as idealized or overly formal meanings, unless expressly defined as such herein.

Please refer to FIG. 1A and FIG. 1B, which are schematic diagrams of the leak-proof coffee cup cover structure of an embodiment of the present invention, wherein FIG. 1A is a schematic diagram of the front side of the leak-proof coffee cup cover, and FIG. 1B is a schematic diagram of the back side of the leak-proof coffee cup cover. Please refer to FIG. 1A and FIG. 1B at the same time. The leakproof coffee cup cover 10 includes a cup cover body 11 and a leakproof member 12. The cup cover body 11 is circular in shape, including a cup cover surface 111 and a cup cover edge 112. The cup cover edge 112 is disposed around the cup cover surface 111. In this embodiment, the cup cover edge 112 can be disposed at 90° to the cup cover surface 111, so that the radius of the cup cover surface 111 is consistent with the radius of the ring at the end of the cup cover edge 112, but the present disclosure is not limited to this. In other embodiments, the cup lid edge 112 may be designed to have an angle of more than 90° with the cup lid surface 111, so that the radius of the ring at the rear end of the cup lid edge 112 is larger than the radius of the cup lid surface 111, so as to match a coffee cup with a larger diameter. A groove 113 may be provided at the rear end of the cup lid edge 112 to correspond to the top of the cup edge of the coffee cup, and the groove 113 may be slightly smaller than the size of the cup edge of the coffee cup, so that when the leakproof coffee cup cover 10 is placed on the coffee cup, the inner side wall of the groove 113 can fit closely with the cup edge, providing a sealing effect, and preventing a gap from being generated to allow coffee to flow out from the cup lid edge 112.

The cup cover surface 111 has a first surface 11A and a second surface 11B. The first surface 11A faces the inner space of the coffee cup, and the second surface 11B faces the outside, that is, the direction facing the user, relative to the first surface 11A. The cup cover surface 111 is provided with a coffee outlet 114. The coffee outlet 114 is adjacent to the cup cover edge 112. The coffee outlet 114 can be an opening in a square, circular, elliptical or other shape, and passes through the first surface 11A and the second surface 11B. After the leak-proof coffee cup cover 10 is put on the coffee cup, the user can drink coffee through the coffee outlet 114 without opening the leak-proof cup cover 10, thereby improving the convenience of drinking. However, when the user moves or takes the coffee cup, the coffee may easily spill out of the coffee outlet 114 due to shaking or swaying, causing various inconveniences. When the coffee inside is hot, it is more likely to cause burns and other safety hazards. In view of this, the present disclosure further provides a leak-proof member 12 to prevent the above problem from occurring.

The leak-proof member 12 is disposed on the first surface 11A of the cup cover surface 111 and extends toward the cup cover edge 112 at an inclined angle. As shown in the figure, the leak-proof member 12 is an annular structure, which is disposed from a certain distance from the cup cover edge 112 on the first surface 11A toward the cup cover edge 112 to form a structure like a retaining wall to block the leakage angle of the inner space toward the coffee outlet 114. Even if the coffee cup is shaken and the coffee flows toward the coffee outlet 114, the leak-proof member 12 can block the coffee from flowing out of the coffee outlet 114, thereby avoiding the accidental occurrence of burns caused by coffee splashing or spraying. The leak-proof member 12 can extend to the coffee outlet 114, and the projection area of the leak-proof member 12 on the first surface 11A can partially cover the coffee outlet 114, but there is still a certain spacing distance between the leak-proof member 12 and the edge of the cup lid 112, so that a flow channel is formed between the leak-proof member 12 and the edge of the cup lid 112, that is, when the user tilts the coffee cup, the coffee can still flow out of the coffee outlet 114 through the flow channel, and will not hinder the inconvenience of the user when drinking.

Referring to FIG. 2, it is a cross-sectional schematic diagram of the leak-proof coffee cup cover of the embodiment of the present invention. Please refer to FIG. 1A and FIG. 1B at the same time. The leak-proof coffee cup cover 10 is a cross-sectional schematic diagram of the aforementioned embodiment. As shown in the figure, the leak-proof coffee cup cover 10 includes a cup cover body 11 and a leak-proof member 12. The cup cover body 11 includes a cup cover surface 111 and a cup cover edge 112. The cup cover edge 112 is arranged around the cup cover surface 111. The cup cover edge 112 is provided with a groove 113 to correspond to the top of the cup edge of the coffee cup 90, so that the leak-proof coffee cup cover 10 can cover the opening of the coffee cup 90 to prevent the coffee in the internal space 90A from flowing out. The cup cover surface 111 is provided with a coffee outlet 214, which is adjacent to the cup cover edge 112 and serves as an opening for the user to drink. As described in the above embodiment, although the coffee outlet 114 is much smaller than the opening of the original coffee cup 90, the coffee in the inner space 90A may still splash out from the coffee outlet 114 when shaken. Therefore, the present disclosure provides a leak-proof member 12 to prevent the coffee from leaking from the coffee outlet 114.

The leak-proof member 12 is disposed on the surface of the cup cover surface 111 facing the inner space 90A, and extends toward the cup cover edge 112 at an inclined angle. The leak-proof member 12 blocks the leakage angle of the inner space 90A toward the coffee outlet 114, but a flow channel can still be formed between the leak-proof member 12 and the cup cover edge 112, so that the user can drink coffee. The cup cover body 11 and the leak-proof member 12 can be an integrally formed structure, and can be manufactured by a single mold during manufacturing, reducing the production process. The material forming the cup cover body 11 and the leak-proof member 12 can be polystyrene or polypropylene, and the leak-proof coffee cup cover 10 is manufactured by injection molding.

In the leakproof coffee cup cover 10, the cup cover edge 112 may have a vertical height on the cup cover surface 111. When the leakproof member 12 is provided, the length of its structural extension is slightly lower than the vertical height of the cup cover edge 112. The leakproof member 12 is provided mainly to block the side of the coffee outlet 114 toward the vertical space of the coffee cup to prevent coffee from leaking in this direction. If the leakproof member 12 extends too much and blocks the outflow channel, it will affect the user's drinking process and cause inconvenience. The leakproof member 12 may have different implementation shapes, which will be further described in the following implementation.

Referring to FIG. 3, it is a schematic diagram of the leak-proof member structure of an embodiment of the present invention. As shown in the figure, the leak-proof coffee cup lid 20 comprises a cup lid body 21 and a leak-proof member 22. The figure shows a schematic plan view in the direction of the first surface of the cup lid body 21. The cup lid body 21 has a cup lid surface 211, and a cup lid edge 212 is arranged around the cup lid surface 211. A coffee outlet 214 is arranged near the cup lid edge 212 on one side. Different from the aforementioned embodiment, the leak-proof member 22 is disposed around the coffee outlet 214 in a U-shaped structure, the notch of the U-shaped structure faces the edge of the cup cover 212, and the U-shaped structure surrounds the coffee outlet 214, so that the leakage angle of the coffee outlet 214 toward the inner space of the coffee cup can be blocked by the leak-proof member 22, thereby preventing coffee from leaking from the coffee outlet 214 when the coffee cup is shaken or swung.

The leak-proof member 22 extends from the surface of the cup cover surface 211 toward the inner space of the coffee cup, and its U-shaped structure may have an inclined angle, and is arranged from the surface of the cup cover body 21 toward the cup cover edge 212. Similar to the above-mentioned embodiment, the extension height of the leak-proof member 22 is less than the vertical height of the cup cover edge 212 relative to the cup cover surface 211, so that when the user drinks, it can be ensured that the outflow channel can flow out smoothly without being blocked, thereby avoiding affecting the drinking experience.

Referring to FIG. 4, it is a schematic diagram of a leak-proof member structure of another embodiment of the present invention. As shown in the figure, the leak-proof coffee cup lid 30 comprises a cup lid body 31 and a leak-proof member 32. The figure shows a plan view in the direction of the first surface of the cup lid body 31. The cup lid body 31 has a cup lid surface 311, and a cup lid edge 312 is arranged around the cup lid surface 311. A coffee outlet 314 is arranged near the cup lid edge 312 on one side. Different from the above-mentioned embodiment, the leak-proof member 32 is disposed on the surface of the cup cover surface 311 in a spiral structure, and the tail of the spiral structure faces the coffee outlet 314, so that the leakage angle of the coffee outlet 314 toward the inner space of the coffee cup can be blocked by the leak-proof member 32, thereby preventing the coffee from leaking from the coffee outlet 314 when the coffee is shaken or swung. The spiral structure can make the overall weight of the leak-proof coffee cup cover 30 more even, making the mold development in the manufacturing process more convenient and improving the feasibility of manufacturing.

The leak-proof member 32 also extends from the surface of the cup cover surface 311 toward the inner space of the coffee cup, and may have an inclined angle at the tail end near the coffee outlet 314, and is arranged from the surface of the cup cover body 31 toward the cup cover edge 312, and the spiral structure as a whole may be inclined toward the periphery of the cup cover edge 312. In other embodiments, the front end of the spiral structure near the center of the cup cover surface 311 may also be arranged vertically, and adjusted according to the design of the forming mold. Similar to the aforementioned embodiment, the extension height of the leak-proof member 32 is less than the vertical height of the cup cover edge 312 relative to the cup cover surface 311, so that when the user drinks, it can be ensured that the outflow channel can flow out smoothly without being blocked, so as to avoid affecting the drinking experience.

Referring to FIG. 5, it is a schematic diagram of another embodiment of a leak-proof coffee cup cover of the present invention. As shown in the figure, the leak-proof coffee cup cover 40 includes a cup cover body 41 and a leak-proof member 42. The cup cover body 41 includes a cup cover surface 411 and a cup cover edge 412. The cup cover edge 412 is disposed around the cup cover surface 411. The cup cover edge 412 is provided with a groove 413 to correspond to the top of the cup edge of the coffee cup, so that the leak-proof coffee cup cover 40 can cover the opening of the coffee cup to prevent the coffee in the internal space from flowing out. The cup cover surface 411 is provided with a coffee outlet 414, which is adjacent to the cup cover edge 412 and serves as an opening for the user to drink.

The leak-proof member 42 is disposed on the surface of the cup cover surface 411 facing the inner space, and extends toward the cup cover edge 412 at an inclined angle. The leak-proof member 42 blocks the leakage angle of the inner space toward the coffee outlet 414, but an outflow channel can still be formed between the leak-proof member 42 and the cup cover edge 412, so that the user can drink coffee. The leak-proof member 42 may have a guide member 421, which is disposed at the rear end of the leak-proof member 42 and is an extension structure of the leak-proof member 42. The guide member 421 and the leak-proof member 42 have a first angle S, and the first angle S can be 60° to 120°. The guide member 421 is provided so that when drinking, the coffee can flow out along the guide member 421 when flowing out of the outflow channel, so that when drinking, the coffee will not splash due to flowing to the tail end of the leak-proof member 42. The cup cover body 41 and the leak-proof member 42 can be an integrally formed structure, and can be manufactured by a single mold during manufacturing, reducing the production process. The material forming the cup cover body 41 and the leak-proof member 42 can be polystyrene or polypropylene, and the leak-proof coffee cup cover 40 is manufactured by injection molding.

In addition, a sealing member 415 and a receiving groove 416 corresponding to the shape of the sealing member 415 can be provided at the coffee outlet 414 on the second surface of the cup cover 411 facing outward.
