Description

Technical Field

[0001] This utility model relates to a cup lid, specifically a coffee cup lid. Background Technology

[0002] Disposable coffee cups are common containers for takeaway coffee, serving primarily as portable options, heat protection, and brand display. Most coffee cups feature a double-layered structure: the outer paper layer insulates against heat, preventing burns, and some materials (such as corrugated cardboard or kraft paper) enhance grip comfort; the outer cup can be customized with patterns or materials (such as coated paper or environmentally friendly ink printing), becoming a vehicle for brand promotion; suitable for fast-paced scenarios like takeaway and office use, requiring no washing, and is also a commonly used coffee container in the delivery industry. The lid is a crucial component of the coffee cup; traditional disposable coffee cup lids have a simple structure (such as...). Figure 4 As shown in the left image), this type of lid consists only of a lid body, the outer edge of the lid body, and the drinking spout. However, this type of lid is not splash-proof, making it suitable for indoor and office use, but not for carrying around. Therefore, coffee cup lids with a small lid that can cover the drinking spout have emerged (such as...). Figure 4 (As shown in the right figure), however, this type of coffee cup lid also has defects. Because the brewed coffee is at a high temperature and the top is usually left with space and is not filled very full, the expansion of the hot air may push the lid off. Since the outer edge of the coffee cup is breathable, it is easy to spill out from the outer edge of the cup when it is delivered or carried. Therefore, the lack of a necessary breathable and splash-proof structure is not conducive to delivery and carrying. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide a coffee cup lid.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a coffee cup lid, including a lid body and a drinking opening on one side of the lid body surface, an outer edge of the lid body for fastening onto the cup body, a reflux chamber and an venting chamber that communicate with each other on the other side of the lid body surface, a reflux and venting port at the bottom of the reflux chamber, and a venting hole communicating with the outside of the lid body surface at the top of the venting chamber, and an openable and closable top cover that covers the drinking opening when the top cover is fastened.

[0005] Furthermore, the reflux chamber and the exhaust chamber are separated by a partition protruding from the cover, and the two ends of the partition are provided with downwardly recessed connecting channels, the bottom of which is higher than the bottom of the reflux chamber and the exhaust chamber.

[0006] Furthermore, the inner side of the top cover is provided with a plug structure that snaps into the drinking spout.

[0007] Furthermore, the top cover is circular and covers the entire upper surface of the cover body. It is divided into front and rear parts, one side of which is used to cover the return cavity and the exhaust cavity. A bending structure is provided between the two parts.

[0008] Furthermore, the inner surface of the top cover is fixed with an edge structure that snaps into and inserts into the inner edge of the return cavity and the exhaust cavity.

[0009] Furthermore, the vent is located on the top cover and extends through it. A baffle cylinder is fixed to the inner surface of the top cover where the vent is located. When the top cover is fastened to the return cavity and the vent cavity, a gap is left between the lower end of the baffle cylinder and the bottom surface of the vent cavity.

[0010] Furthermore, the cover and the top cover are integrally formed from plastic through a bent connecting plate, and when the top cover is fastened, the connecting plate is completely attached to the edge of the cover.

[0011] Furthermore, a circular protrusion is provided at the center of the cover, which protrudes from the surface of the cover, and a positioning hole is opened at the center of the upper cover. When the upper cover is fastened, the positioning hole is fastened to the circular protrusion.

This forms staggered ventilation channels, which can ensure the exhaust of hot air and prevent coffee from splashing out. 2. The two ends of the partition are provided with downward-recessed connecting channels. The bottom of the connecting channels is higher than the bottom of the return chamber and the exhaust chamber. In this way, even when the block is shaken violently, a small amount of coffee may enter the return chamber through the return and exhaust ports. Since the bottom of the connecting channels is higher than the bottom of the return and exhaust chambers, the connecting channels can form a connection while also acting as a certain obstruction. This ensures ventilation while preventing coffee from entering the exhaust chamber, thus better preventing coffee from flowing out and ensuring the exhaust effect.

[0015] 3. The vent is located on the top cover and extends through it. A baffle cylinder is fixed to the inner surface of the top cover where the vent is located. When the top cover is fastened to the reflux chamber and the vent chamber, there is a gap between the lower end of the baffle cylinder and the bottom surface of the vent chamber. The baffle cylinder further improves the effect of blocking liquid. 4. A circular protrusion is provided in the center of the cover, which is raised above the surface of the cover. A positioning hole is opened in the center of the top cover. When the top cover is fastened, the positioning hole is fastened to the circular protrusion, making the fastening more secure.

[0019] The following is a detailed description of this embodiment with reference to the accompanying drawings: This embodiment provides a coffee cup lid; please refer to the accompanying drawings in the instruction manual. Figure 1-3 .

[0020] like Figure 1-3As shown, a coffee cup lid includes a lid body 1 and a drinking spout 2 on one side of the lid body 1. The lid body 1 has an outer edge 3 for fastening onto the cup body. On the other side of the lid body 1, a reflux chamber 4 and a vent chamber 5 are respectively provided, communicating with each other. The bottom of the reflux chamber 4 has a reflux and vent port 6, and the top of the vent chamber 5 has a vent hole 7 communicating with the outside of the lid body 1. The lid body 1 has an openable and closable upper cover 8. When the upper cover 8 is closed, it covers the drinking spout 2, and the reflux chamber 4 and the vent chamber 5 are connected by a protrusion on the lid body 1. The partition 9 is separated, and the two ends of the partition 9 are provided with downwardly recessed connecting channels 10. The bottom of the connecting channels 10 is higher than the bottom of the return chamber 4 and the exhaust chamber 5. In this way, even when the machine is shaken violently, a small amount of coffee enters the return chamber 4 through the return and exhaust ports 6. Since the bottom of the connecting channels 10 is higher than the bottom of the return chamber 4 and the exhaust chamber 5, the connecting channels 10 can form a connection while also playing a certain blocking role. This ensures ventilation while preventing coffee from entering the exhaust chamber 5, thus better preventing coffee from flowing out and ensuring the exhaust effect.

[0021] Specifically: The inner side of the top cover 8 is provided with a plug structure 11 that snaps into the drinking spout 2, which can more firmly block the drinking spout 2 when it is snapped on; the top cover 8 is circular and covers the entire upper surface of the cover body 1, and is divided into front and rear parts. One side is used to cover the reflux chamber 4 and the exhaust chamber 5. A bending structure 12 is provided between the two parts. If the bending structure 12 is thin, it is easy to bend along the "line" formed by the bending structure 12. Only the part of the top cover 8 covering the drinking spout 2 is opened, while the top cover 8 of the reflux chamber 4 and the exhaust chamber 5 is kept closed, which is convenient for drinking.

[0022] The inner surface of the top cover 8 is fixed with an edge structure 13 that snaps into and inserts into the inner edge of the reflux chamber 4 and the exhaust chamber 5. The edge structure 13 can ensure the firmness of this part when the top cover 8 is snapped on. The exhaust hole 7 is provided on the top cover 8 and penetrates the top cover 8. The inner surface of the top cover 8 with the exhaust hole 7 is fixed with a baffle cylinder 14. When the top cover 8 is snapped on the reflux chamber 4 and the exhaust chamber 5, there is a gap between the lower end of the baffle cylinder 14 and the bottom surface of the exhaust chamber 5. The baffle cylinder 14 further improves the effect of blocking liquid.

[0023] For ease of processing and use, the cover 1 and the upper cover 8 are integrally formed from plastic via a bent connecting plate 15, and when the upper cover 8 is fastened, the connecting plate 15 is completely fitted against the edge of the cover 1, such as... Figure 3As shown, the lid 1 has a circular protrusion 16 at its center, and the upper cover 8 has a positioning hole 17 at its center. When the upper cover 8 is closed, the positioning hole 17 engages with the circular protrusion 16, making the closure more secure. The outer edge of the upper surface of the lid 1 is bent upward to form a ring-shaped cup mouth structure 18. The cup mouth structure 1 facilitates drinking coffee. The outer edge of the upper cover 8 on the drinking spout 2 side is provided with a push plate 19 for lifting and flipping open the upper cover 8. The outer end of the push plate 19 can be moved away from the cup mouth structure 18. The push plate 19 can be L-shaped. After the top cover 8 is closed, the push plate 19 can fit tightly against the inner wall of the cup mouth structure 18. When opening, the push plate 19 can be pushed upward. When the connecting plate 15 is closed, an outwardly protruding arc-shaped buckle 20 is provided on the connecting plate 15 at the inner edge of the cup mouth structure 18. After the front part of the top cover 8 is opened along the bending structure 12, the outer edge of the push plate 19 can be below the arc-shaped buckle 20, which forms a blockage on the front part of the top cover 8 after it is opened, preventing the front part of the top cover 8 from tilting upward and affecting the drinking of coffee.

[0024] Of course, the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
