Description

A cup lid and a cup Technical Field

[0001] The utility model relates to the field of cups, in particular to a cup cover and a cup. Background Art

[0002] Cups are necessities in daily life. In order to prevent the liquid in the cup from spilling or the liquid in the cup from being exposed to the air for a long time, the cup will be equipped with a cup lid according to the needs of use.

[0003] Currently, cup lids and cups are primarily connected by threaded or snap-on connections. The snap-on connection method varies depending on the cup material, resulting in varying sealing and connection effectiveness. For example, the softer plastic cups used in milk tea shops and juice shops can easily become loose after snapping onto the lid, forcing them to lie flat after filling. Harder plastic cups, while watertight and difficult to separate, are difficult to open, and excessive force can cause liquid to spill.

[0004] The lid of a thermos cup (or thermos pot) is typically connected to the cup body using a threaded connection. Some thermos cups also feature a push-button switch in the middle for easy opening and closing. However, these lids are relatively complex, require numerous components, require multiple assembly steps, are heavy, and are expensive. Consequently, these thermos cups are relatively expensive. Consequently, a lightweight, watertight, low-cost, and easy-to-open lid is currently unavailable.

[0005] It can be seen that the existing technology still needs to be improved and enhanced.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore, cannot be understood as a limitation on the present invention. In addition, "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0038] Please refer to Figures 1-6. The present invention provides a cup cover A1, comprising a fixing ring 1, which also includes a sealing cover 3 and an elastic connecting structure 2; the fixing ring 1, the elastic connecting structure 2 and the sealing cover 3 are connected in sequence from the outside to the inside; the elastic connecting structure 2 is provided with at least one water outlet 4; the middle part of the fixing ring 1 is provided with a water outlet 11; the elastic connecting structure 2 is used to change the position of the sealing cover 3 so that the sealing cover 3 closes or opens the water outlet 11. The lower part of the fixing ring 1 is detachably connected to the cup body A2. Please refer to Figures 2 and 5. The bottom surface of the fixing ring 1 can be provided with an annular groove 14 for clamping with the top of the cup body A2. Please refer to Figure 8. The lower part of the fixing ring 1 can also be provided with an internal thread to adapt to the cup body A2 with an external thread on the upper part. When it is necessary to close the water outlet 11, press the sealing cover 3, the elastic connecting structure 2 flips down, and the sealing cover 3 covers the water outlet 11. When it is necessary to open the water dispenser, the sealing cover 3 is pulled up, the elastic connection structure 2 is flipped upward, the sealing cover 3 leaves the water outlet 11 , and the water outlet 11 is connected to the water outlet 4 .

[0039] Please refer to Figures 2 and 5. In one embodiment, when the cup cover A1 is in the open state, the elastic connection structure 2 is arranged upward from the fixing ring 1 to the sealing cover 3. The sealing cover 3 and the elastic connection structure 2 form a stable structure that bulges upward. At this time, the elastic connection structure 2 is in an upward flip-up state, so that the sealing cover 3 is located above the water outlet 11. Please refer to Figures 3 and 6. When the cup cover A1 is in the closed state, the elastic connection structure 2 is arranged downward from the fixing ring 1 to the sealing cover 3. The sealing cover 3 and the elastic connection structure 2 form a stable structure that is concave downward. The sealing cover 3 abuts the fixing ring 1 to close the water outlet 11. At this time, the elastic connection structure 2 is in a downward flip-down state. The fixing ring 1, the elastic connection structure 2 and the sealing cover 3 are fixedly connected in sequence.

[0040] Please refer to Figures 10 and 11. In one embodiment, the elastic connection structure 2 may be an elastic connection ring 21. When the elastic connection ring 21 is turned up or down, it takes the shape of a truncated cone peripheral wall.

[0041] Referring to Figure 12 , in one embodiment, the elastic connection structure 2 includes a plurality of connecting pieces 22 arranged obliquely from the outside to the inside, with the water outlet 4 formed between adjacent connecting pieces 22. Specifically, the length of the connecting piece 22 is greater than the horizontal distance between the sealing cover 3 and the fixing ring 1, so that the connecting piece 22 can be straightened and maintained in a stable configuration when arranged obliquely.

[0042] The entire cup cover A1 can be made of elastic plastic materials such as silicone. Preferably, the cup cover A1 can be made by an integral molding process such as injection molding, which does not require assembly and has high production efficiency.

[0043] The inner diameter of the upper portion of the retaining ring 1 is larger than the diameter of the sealing cover 3, while the inner diameter of the lower portion of the retaining ring 1 is smaller than the lower diameter of the sealing cover 3. The retaining ring 1 forms a chamber with a larger diameter at the top and a smaller diameter in the middle. This chamber connects the interior of the cup body A2 and the water outlet 4. The upper diameter of the chamber is larger than the lower diameter of the sealing cover 3; the lower diameter of the chamber is smaller than the lower diameter of the sealing cover 3. When the sealing cover 3 is pressed downward, the lower portion of the sealing cover 3 abuts against the lower wall of the chamber.

[0044] Figures 2 and 5 are schematic diagrams of the cup cover A1 in an open state. At this time, the peripheral wall of the elastic connection structure 2 is arranged to be inclined upward from the outside to the inside, and the sealing cover 3 is not connected to the inner wall of the fixing ring 1. At this time, a water outlet channel 15 is formed between the sealing cover 3 and the fixing ring 1. The lower end of the water outlet channel 15 is connected to the interior of the cup body A2, and the upper end of the water outlet channel 15 is connected to the water outlet hole 4.

[0045] Figures 3 and 6 illustrate cup lid A1 in its closed position. Due to the variability of the elastic connecting structure 2, when the sealing lid 3 is pressed, the elastic connecting structure 2 deforms as the sealing lid 3 moves downward. When fully tilted downward, it reaches a stable state, and even after the external force is removed, it maintains the configuration shown in Figures 3 and 6. When the sealing lid 3 is pressed downward, its lower circumferential wall abuts the inner circumferential wall of the retaining ring 1, severing the connection between the water outlet channel 15 and the interior of the cup body A2. The shape of the water outlet channel 15 also narrows due to the changes in the position and shape of the elastic connecting ring 21 and the sealing lid 3.

[0046] Please refer to Figures 2 and 3. In one embodiment, the inner side wall of the fixing ring 1 is provided with a first annular sealing strip 12. The area enclosed by the first annular sealing strip 12 forms a water outlet 11. When the sealing cover 3 closes the water outlet 11, the first annular sealing strip 12 abuts against the sealing cover 3. When closing is required, the sealing cover 3 is pressed down, causing the elastic connection structure 2 to flip downward. At this time, the upper surface of the first annular sealing strip 12 abuts against the lower surface of the sealing cover 3 to close the water outlet 11. Since the first annular sealing strip 12 is elastic, it will undergo slight elastic deformation during closing, further pressing the first annular sealing strip 12 against the sealing cover 3.

[0047] Furthermore, the middle part of the sealing cover 3 is recessed downward. In the open state, the connection between the sealing cover 3 and the elastic connection structure 2 is an upward convex structure. The sealing cover 3 is located above the first annular sealing strip 12, and the water outlet channel 15 is located between the sealing cover 3 and the first annular sealing strip 12. At this time, water flows through the water inlet 11 and the water outlet channel 15 in sequence, and finally flows out from the water outlet 4; in the sealed state, the elastic connection structure 2 flips downward, and the sealing cover 3 moves downward, so that the first annular sealing strip 12 abuts against the sealing cover 3, and the water outlet channel 15 is closed. At the same time, the sealing cover 3 closes the water inlet 11; the inner side of the first annular sealing strip 12 convexes upward, which can improve its structural strength, so as to enhance the abutment effect between the first annular sealing strip 12 and the sealing cover 3 and improve watertightness.

[0048] Please refer to Figures 5 and 6. In one embodiment, a second annular sealing strip 31 is provided at the bottom of the sealing cover 3; an annular protrusion 13 is provided at the lower portion of the inner wall of the fixing ring 1; the middle portion of the annular protrusion 13 forms the water outlet 11; and the second annular sealing strip 31 is interference fit with the water outlet 11. The diameter of the water outlet 11 is smaller than the outer diameter of the second annular sealing strip 31. When sealing is required, the sealing cover 3 is pressed down until the second annular sealing strip 31 passes through the annular protrusion 13. At this time, the inner wall of the fixing ring 1 below the annular protrusion 13 abuts, and the top surface of the second annular sealing strip 31 presses against the bottom surface of the annular protrusion 13. The provision of the annular protrusion 13 can increase the contact area between the inner wall of the fixing ring 1 and the second annular sealing strip 31, so that the sealing effect of the second annular sealing strip 31 is better.

[0049] Furthermore, the middle portion of the sealing cover 3 is recessed downward, and the top of the second annular sealing strip 31 is fixedly connected to the edge of the sealing cover 3. The middle portion of the sealing cover 3 has an arched cross-section, which effectively enhances outward rebound force. When the lower portion of the sealing cover 3 and the second annular sealing strip 31 form an interference fit with the lower portion of the retaining ring 1, the arched shape allows the lower portion of the sealing cover 3 and the second annular sealing strip 31 to press more firmly against the inner circumferential wall of the retaining ring 1, improving watertightness.

[0050] Furthermore, referring to Figure 9, a trumpet-shaped water passage 16 is formed in the center of the retaining ring 1. This trumpet-shaped water passage 16 has a centrally raised channel wall. The second annular sealing strip 31 passes through the central portion and engages with the raised channel wall. This trumpet-shaped design also allows for a smoother transition of the channel wall from top to bottom and vice versa, ensuring smooth passage of the second annular sealing strip 31 and ensuring watertightness.

[0051] Referring to Figures 5 and 6 , the bottom of the peripheral wall of the second annular sealing strip 31 is convex outward, forming an inwardly concave arcuate groove on the peripheral wall of the second annular sealing strip 31. This arcuate groove mates with the annular protrusion 13, increasing the contact area between the second annular sealing strip 31 and the annular protrusion 13 and improving the sealing effect. The outward convex bottom of the second annular sealing strip 31 resembles a barb in cross-section, which increases the adhesion of the second annular sealing strip 31 to the inner wall of the retaining ring 1. This ensures that the sealing lid 3 does not leak even when the cup is inverted after sealing.

[0052] Referring to Figures 2 and 7-9, in one embodiment, the outer wall of the elastic connection structure 2 is fixedly connected to the middle portion of the inner wall of the fixing ring 1; the inner wall of the elastic connection structure 2 is fixedly connected to the upper portion of the sealing cover 3. In this embodiment, the upper portion of the inner circumferential wall of the fixing ring 1 serves as a water deflector. When drinking water, it flows out of the water outlet 4 and enters the human mouth through the upper portion of the inner circumferential wall of the fixing ring 1.

[0053] Referring to Figures 10-12, in one embodiment, the elastic connection structure 2 is circumferentially provided with a plurality of water outlet holes 4, wherein the water outlet holes 4 can be circular, strip-shaped, or elliptical. By providing the water outlet holes 4 in different directions on the elastic connection structure 2, water can be dispensed from the cup at different angles, making it convenient to use.

[0054] Referring to Figures 3 and 6 , in one embodiment, a lid handle 5 is provided on the top of the sealing cover 3 to facilitate lifting the sealing cover 3 from the closed state to the open state. In addition to the lid handle 5 , a groove or a latch hole may be provided on the top surface of the sealing cover 3 , or a hook or other structure may be provided on the top surface of the sealing cover 3 to facilitate lifting the sealing cover 3 .

[0055] If the sealing lid 3 is not provided with a structure having a similar function to the lid handle 5, the sealing lid 3 can also be opened by using a cup body A2 with good elasticity (e.g., a flexible plastic material such as silicone). When the cup lid A1 is in the closed state, the cup body A2 can be squeezed by hand to increase the internal pressure of the seal, forcing the sealing lid 3 to move upward.

[0056] Referring to Figures 3 and 6 , the lid handle 5 is cylindrical and has a cavity 51 disposed therein. When grasped, the cavity 51 acts as a deformation space. The twisting of the lid handle 5 increases the contact area between the lid handle 5 and the hand, thereby increasing friction. Optionally, the bottom of the cavity 51 is connected to a lower portion, facilitating integrated molding.

[0057] Please refer to Figures 13 and 14. A cup includes a cup body A2 and the cup cover A1 described above; the bottom of the fixing ring 1 is provided with an annular groove 14, and the top of the cup body A2 is engaged with the annular groove 14. Preferably, the top of the cup body A2 is interference fit with the annular groove 14 on the cup cover A1. The cup cover A1 and the cup body A2 can both be made of silicone, which has good elasticity, is resistant to aging, is lightweight and easy to process. When the silicone cup cover A1 is used in combination with the silicone cup body A2, the elastic top of the cup body A2 is more tightly engaged with the annular groove 14 in the elastic cup cover A1.

[0058] Referring to Figures 13 and 14 , in one embodiment, a first annular ridge 6 is provided on the top outer peripheral wall of the cup body A2. This first annular ridge 6 is positioned within the annular retaining groove 14. A second annular ridge 18 is provided on the inner bottom of the outer groove wall 17 of the annular retaining groove 14, with the top surface of the second annular ridge 18 abutting the bottom surface of the first annular ridge 6. Viewed in cross section, the outer groove wall 17 of the annular retaining groove 14 acts like an inwardly curved gripping arm, clamping the first annular ridge 6 within the annular retaining groove 14.

[0059] Please refer to Figures 13 and 14. Furthermore, the cross-section of the inner groove wall 19 of the annular groove 14 is an inwardly curved arch. The bottom of the inner groove wall 19 abuts against the inner circumferential wall of the cup body A2. The height of the first annular ridge 6 is the same as the height of the recessed area formed by the arch. When the outer groove wall 17 of the annular groove 14 squeezes the outer wall of the cup body A2, and the inner groove wall 19 of the annular groove 14 squeezes the inner wall of the cup body A2, the cup body A2 will be deformed, forcing the deformed part to enter the recessed area, so that the cross-section of the top of the cup body A2 is S-shaped, which increases the contact area with the top of the cup body A2 and the cup cover A1, and makes it more difficult for the cup body A2 and the cup cover A1 to separate, and the watertightness is also better.

[0060] In summary, the present invention connects the fixing ring 1 and the sealing cover 3 via the elastic connection structure 2, allowing the cup to be closed or opened by pressing or pulling up the sealing cover 3. The overall structure of the cup cover A1 is simple, and can be integrally formed from an elastic plastic material such as silicone. It requires no assembly, is lightweight, and is low-cost, while maintaining excellent watertightness.

[0061] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
