[0003] At present, the cup lid and the cup are mainly connected by thread or snap-on. Among them, the snap-on method will show different sealing and connection effects depending on the material of the cup. For example, the soft plastic cups used in milk tea shops or juice shops are very easy to loosen after the cup body and the cup lid are snap-on, and can only be placed flat after filling with liquid. Another type of plastic cup with a harder texture is watertight, and the cup lid and cup body are not easy to separate, but it is difficult to open, and if too much force is used, it will cause liquid to spill.

[0004] The lid of a thermos cup (thermos pot) is basically connected to the cup body by threads. Some of the lids of thermos cups are also provided with a push switch in the middle to facilitate opening and closing, but they have the disadvantages of relatively complex structure, many accessories, many assembly processes, heavy weight and high cost. Therefore, the price of such thermos cups is relatively high. Therefore, there is no cup lid that is light in weight, watertight, low in cost and easy to open and close.

Specific embodiments

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] In the description of the present utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation to the present utility model. 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 quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise stated, the meaning of "a plurality" is two or more.

[0037] Please refer to Figure 1-6 , the present utility model provides a cup lid A1, including a fixing ring 1. Among them, it further includes a sealing cover 3 and an elastic connection structure 2; the fixing ring 1, the elastic connection structure 2, and the sealing cover 3 are connected in sequence from outside to inside; at least one water outlet hole 4 is provided on the elastic connection structure 2; a water passing hole 11 is provided in the middle of the fixing ring 1; the elastic connection structure 2 is used to change the position of the sealing cover 3 to make the sealing cover 3 close or open the water passing hole 11. The lower part of the fixing ring 1 is detachably connected to the cup body A2. Please refer to Figure 2 , 5 , the bottom surface of the fixing ring 1 may be provided with an annular card slot 14 for snap-fitting with the top of the cup body A2. Please refer to Figure 8 , the lower part of the fixing ring 1 may also be provided with an internal thread, which is adapted to the cup body A2 provided with an external thread at the upper part. When it is necessary to close the water passing hole 11, press the sealing cover 3, and the elastic connection structure 2 turns downward, and the sealing cover 3 covers the water passing hole 11. When it is necessary to open it, pull up the sealing cover 3, and the elastic connection structure 2 turns upward, and the sealing cover 3 leaves the water passing hole 11, and the water passing hole 11 is communicated with the water outlet hole 4.

[0038] Please refer to Figure 2 , 5, in one embodiment, when the cup lid A1 is in the open state, the elastic connection structure 2 is inclined upward from the fixed ring 1 to the sealing cover 3, and the sealing cover 3 and the elastic connection structure 2 form a stable upward convex structure. At this time, the elastic connection structure 2 is in the upward-flipped state, so that the sealing cover 3 is located above the water passing hole 11. Please refer to Figure 3 、 6 , when the cup lid A1 is in the closed state, the elastic connection structure 2 is inclined downward from the fixed ring 1 to the sealing cover 3, and the sealing cover 3 and the elastic connection structure 2 form a stable downward concave structure. The sealing cover 3 abuts against the fixed ring 1 to close the water passing hole 11. At this time, the elastic connection structure 2 is in the downward-flipped state. The fixed ring 1, the elastic connection structure 2, and the sealing cover 3 are fixedly connected in sequence.

[0039] Please refer to Figure 10 、 11 , in one embodiment, the elastic connection structure 2 can be an elastic connection ring 21. After the elastic connection ring 21 is flipped upward or downward, it has the shape of the peripheral wall of a frustum of a cone.

[0040] Please refer to Figure 12 , in one embodiment, the elastic connection structure 2 includes a plurality of connecting pieces 22 that are inclined from the outside to the inside. The water outlet holes 4 are 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 fixed ring 1, so that the connecting piece 22 can be straightened when it is inclined and is in a stable form.

[0041] The whole of the cup lid A1 can be made of an elastic plastic material such as silica gel. Preferably, the cup lid A1 can be made by an integral molding process such as injection molding, without assembly, and has high production efficiency.

[0042] The inner diameter of the upper part of the fixed ring 1 is greater than the diameter of the sealing cover 3, and the inner diameter of the lower part of the fixed ring 1 is smaller than the lower diameter of the sealing cover 3. The fixed ring 1 encloses a receiving cavity with a large upper diameter and a small middle diameter. The receiving cavity communicates with the inside of the cup body A2 and the water outlet holes 4. The upper diameter of the receiving cavity is greater than the lower diameter of the sealing cover 3; the lower diameter of the receiving cavity is smaller than the lower diameter of the sealing cover 3. When the sealing cover 3 is pressed down, the lower part of the sealing cover 3 abuts against the lower cavity wall of the receiving cavity.

[0043] Figure 2 、 5 is a schematic diagram of the cup lid A1 in the open state. At this time, the peripheral wall of the elastic connection structure 2 is inclined upward from the outside to the inside, and the sealing cover 3 does not contact the inner side wall of the fixed ring 1. At this time, a water outlet channel 15 is formed between the sealing cover 3 and the fixed ring 1. The lower end of the water outlet channel 15 is connected to the inside of the cup body A2, and the upper end of the water outlet channel 15 communicates with the water outlet holes 4.

[0044] Figure 3 、 6 This is a schematic diagram of the cup lid A1 in a closed state. Since the elastic connection structure 2 is variable, after pressing the sealing cover 3, the elastic connection structure 2 will deform as the sealing cover 3 moves downward. When it is completely turned down, it reaches a stable state and remains in the state shown in Figure 3 、 6 after the external force is removed. After the sealing cover 3 is pressed down, the lower peripheral wall of the sealing cover 3 will abut against the inner peripheral wall of the fixed ring 1. At this time, the connection between the water outlet channel 15 and the inside of the cup body A2 is cut off, and the shape of the water outlet channel 15 also becomes narrow due to the changes in the position and shape of the elastic connection ring 21 and the sealing cover 3.

[0045] Please refer to Figure 2 、 Figure 3 In one embodiment, a first annular sealing strip 12 is provided on the inner side wall of the fixed ring 1, and the area surrounded by the first annular sealing strip 12 forms a water passing opening 11; when the sealing cover 3 closes the water passing opening 11, the first annular sealing strip 12 abuts against the sealing cover 3. When it needs to be closed, the sealing cover 3 is pressed down to turn the elastic connection structure 2 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 passing opening 11. Since the first annular sealing strip 12 has elasticity, during closing, the first annular sealing strip 12 will undergo slight elastic deformation to further press the first annular sealing strip 12 tightly against the sealing cover 3.

[0046] 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 passing opening 11, the water outlet channel 15 in sequence, and finally flows out from the water outlet hole 4; in the sealed state, the elastic connection structure 2 is turned downward, and the sealing cover 3 moves downward, causing the first annular sealing strip 12 to abut against the sealing cover 3, closing the water outlet channel 15. At the same time, the sealing cover 3 closes the water passing opening 11; the inner side of the first annular sealing strip 12 protrudes upward, which can improve its structural strength to enhance the abutting effect between the first annular sealing strip 12 and the sealing cover 3 and improve the water tightness.

[0047] Please refer to Figure 5 、 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 part of the inner side wall of the fixing ring 1; a water passing port 11 is formed in the middle of the annular protrusion 13; the second annular sealing strip 31 is in interference fit with the water passing port 11. The diameter of the water passing port 11 is smaller than the outer diameter of the second annular sealing strip 31. When it needs to be closed, 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 side wall of the fixing ring 1 below the annular protrusion 13 abuts, and the top surface of the second annular sealing strip 31 presses on the bottom surface of the annular protrusion 13. The setting 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, making the sealing effect of the second annular sealing strip 31 better.

[0048] Further, the middle part of the sealing cover 3 is recessed downward; the top of the second annular sealing strip 31 is fixedly connected to the edge of the sealing cover 3. The middle cross-section of the sealing cover 3 is in a bow shape, which can effectively improve the outward resilience. When the lower part of the sealing cover 3, the second annular sealing strip 31 and the lower part of the fixing ring 1 are in interference fit, the bow-shaped setting can make the lower part of the sealing cover 3 and the second annular sealing strip 31 press more strongly on the inner peripheral wall of the fixing ring 1, improving the water tightness.

[0049] Furthermore, referring to Figure 9 , a horn-shaped water passing channel 16 is formed in the middle of the fixing ring 1. The horn-shaped water passing channel 16 has a channel wall with a middle protrusion. After the second annular sealing strip 31 passes through the middle thereof, it is clamped with the protruding channel wall. The horn-shaped setting can also make the channel wall of the water passing channel 16 have a relatively gentle transition from top to bottom or from bottom to top. When the second annular sealing strip 31 passes through, it will be more smooth and can ensure the water tightness.

[0050] Please refer to Figure 5 、 Figure 6 , specifically, the bottom of the circumferential wall of the second annular sealing strip 31 protrudes outward, so that an arc-shaped groove recessed inward is formed on the circumferential wall of the second annular sealing strip 31. The arc-shaped groove is adapted to the annular protrusion 13, which can increase the contact area between the second annular sealing strip 31 and the annular protrusion 13 and improve the sealing effect. After the bottom of the second annular sealing strip 31 protrudes outward, from the cross-section, it is like a barb, which can increase the adhesion of the second annular sealing strip 31 to the inner wall of the fixing ring 1, so that after closing, when the water cup is inverted, the sealing cover 3 will not leak water.

[0051] Please refer to Figure 2 、 Figure 7-9, in one embodiment, the outer sidewall of the elastic connection structure 2 is fixedly connected to the middle part of the inner sidewall of the fixing ring 1; the inner sidewall of the elastic connection structure 2 is fixedly connected to the upper part of the sealing cover 3. In this embodiment, the upper part of the inner peripheral wall of the fixing ring 1 can serve as a water guide plate. When drinking water, the water flows out from the water outlet hole 4 and enters the human mouth through the upper part of the inner peripheral wall of the fixing ring 1.

[0052] Please refer to Figure 10-12 , in one embodiment, a plurality of the water outlet holes 4 are circumferentially arranged on the elastic connection structure 2, and the water outlet holes 4 can be circular holes, strip-shaped holes, or elliptical hole structures, etc. By arranging the water outlet holes 4 in different directions on the elastic connection structure 2, the cup can achieve water outlet at different angles, which is convenient to use.

[0053] Please refer to Figure 3 , 6 , in one embodiment, a cover handle 5 is arranged on the upper part of the sealing cover 3, and the cover handle 5 is convenient for pulling up the sealing cover 3 in the closed state to switch to the open state. In addition to arranging the cover handle 5, grooves, clamping holes can also be arranged on the top surface of the sealing cover 3, or a hook can be arranged on the upper part of the sealing cover 3 and other structures convenient for pulling up the sealing cover 3.

[0054] If a structure similar to the cover handle 5 is not arranged on the sealing cover 3, the opening of the sealing cover 3 can also be completed by matching with a cup body A2 with good elasticity (such as using elastic plastic materials such as silica gel). When the cup cover A1 is in the closed state, the internal pressure can be increased by squeezing the cup body A2 by hand, forcing the sealing cover 3 to move upward.

[0055] Please refer to Figure 3 , 6 , further, the cover handle 5 is columnar, and a cavity 51 is arranged inside the cover handle 5. When the hand holds the cover handle 5, the cavity 51 serves as a deformation space. After the cover handle 5 is twisted, the contact area between the surface of the cover handle 5 and the hand can be increased, and the friction force can be increased. Optionally, the bottom of the cavity 51 is communicated with the lower part, which is convenient for integral processing and forming.

[0056] Please refer to Figure 13 , 14 , a cup, comprising a cup body A2 and the above-mentioned cup cover A1; a circular groove 14 is arranged at the bottom of the fixing ring 1, and the top of the cup body A2 is clamped with the circular groove 14. Preferably, the top of the cup body A2 is in interference fit with the circular groove 14 on the cup cover A1. Both the cup cover A1 and the cup body A2 can be made of silica gel. Silica gel has good elasticity, aging resistance, light weight and is easy to process. When the silica gel cup cover A1 and the silica gel cup body A2 are used in combination, the clamping between the elastic top of the cup body A2 and the circular groove 14 in the elastic cup cover A1 is tighter.

[0057] Please refer to Figure 13 and 14 In one embodiment, a first annular rib 6 is provided on the outer peripheral wall of the top of the cup body A2. The first annular rib 6 is placed in the annular groove 14. A second annular rib 18 is provided at the inner bottom of the outer groove wall 17 of the annular groove 14, and the top surface of the second annular rib 18 abuts against the bottom surface of the first annular rib 6. Seen from the cross-section, the outer groove wall 17 of the annular groove 14 is like an inwardly curved gripping arm that clamps the first annular rib 6 in the annular groove 14.

[0058] Please refer to Figure 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 peripheral wall of the cup body A2. The height of the first annular rib 6 is the same as the height of the recess formed by the arch. When the outer groove wall 17 of the annular groove 14 presses against the outer wall of the cup body A2 and the inner groove wall 19 of the annular groove 14 presses against the inner wall of the cup body A2, it will cause the cup body A2 to deform, forcing the deformed part to enter the recess area, making the cross-section of the top of the cup body A2 in an S shape, increasing the contact area between the top of the cup body A2 and the cup lid A1, making it more difficult for the cup body A2 and the cup lid A1 to separate, and also having better water tightness.

[0059] In summary, the present utility model connects the fixing ring 1 and the sealing cover 3 through the elastic connection structure 2, so that the cup can be closed or opened by pressing or pulling up the sealing cover 3. The overall structure of the cup lid A1 is simple, and it can be integrally processed from elastic plastic materials such as silicone, without assembly, light in weight, low in cost, and all having excellent water tightness.

[0060] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solutions and the inventive concept of the present utility model, and all such changes or substitutions should fall within the protection scope of the present utility model.
