Description

Technical Field

[0001] This application relates to the field of daily necessities technology, specifically to a cup lid and a cup having the cup lid. Background Technology

[0002] As living standards gradually improve, consumers have higher demands for the opening mechanisms of water cups. Therefore, while existing cup lids come in various forms such as flip-top, pop-up, and rotating lids, these forms are far from meeting consumer needs. Consequently, many water cups with different opening and closing mechanisms have appeared on the market. However, while there is a wide variety of water cups with opening and closing mechanisms, the overall lid structure is relatively complex, resulting in complicated operation and manufacturing difficulties. Furthermore, existing lid structures also suffer from poor sealing performance. Summary of the Invention

[0003] The main objective of this application is to provide a cup lid and a cup with the cup lid, so as to provide a lid with a simple opening and closing structure, thereby simplifying the structure of the cup lid while ensuring normal drinking function, and at the same time improving the sealing effect of the cup lid on the cup body.

[0004] To achieve the above objectives, this application provides the following technical solution.

[0005] According to a first aspect of this application, a cup lid is provided for covering the mouth of a cup body, wherein the cup lid includes: a lid body, a lid connector, a lid, and a sealing retaining part. The upper surface of the lid body has a liquid outlet; the lid connector is slidably disposed on the surface of the lid body and movable relative to the liquid outlet; the lid is used to cover the liquid outlet, rotatably disposed on the upper surface of the lid connector, and movable together with the lid connector; the sealing retaining part is disposed between the lid connector and the lid, and is capable of applying a force to the lid to seal the liquid outlet.

[0006] According to the cup lid provided in the embodiments of this application, the lid connecting seat is slidably disposed on the surface of the lid body, and the lid is rotatably connected to the upper surface of the lid connecting seat, so that the lid can move together with the lid connecting seat relative to the liquid outlet. When drinking water is needed, the lid and the lid connecting seat are moved together and relatively away from the liquid outlet by external force, so that the lid can open the liquid outlet; when drinking water is not needed, the lid and the lid connecting seat are moved together and relatively closer to the liquid outlet by external force, so that the liquid outlet can be sealed with the cooperation of the sealing retaining part. According to the cup lid of this application, the structure of the cup lid can be simplified while ensuring normal drinking function, thereby simplifying the use and operation of the cup lid and reducing the manufacturing difficulty of the cup lid. Furthermore, due to the provision of the sealing retaining part, the lid can be sealed at the liquid outlet under the action of the sealing retaining part, thereby improving the sealing effect of the cup with this cup lid.

[0007] In some embodiments, the sealing retainer is an elastic member disposed between the cover plate connector and the cover plate.

[0008] In other embodiments, the sealing retainer includes a first magnet disposed on the cover plate connector and a second magnet disposed on the cover plate.

[0009] In an embodiment, the cover plate connecting seat is located on the upper surface of the cover body and can slide along the upper surface of the cover body between a first position and a second position. In the first position, the cover plate can be sealed in the liquid outlet under the action of the sealing retaining part, and can also be flipped outward under the action of external force to detach from the liquid outlet, thereby sliding with the cover plate connecting seat to the second position to expose the liquid outlet.

[0010] In one embodiment, the first end of the cover is used to cover the liquid outlet, and the second end of the cover extends toward the opposite side of the liquid outlet and serves as a pressing end. The first end of the cover is provided with a sealing plug protruding relative to the lower surface. In the first position, there is a predetermined gap between the lower surface of the pressing end and the cover body. When the pressing end is pressed, the first end of the cover is tilted upward, thereby allowing the sealing plug to detach from the liquid outlet.

[0011] In these embodiments, by providing a relatively protruding sealing plug on the lower surface of the first end of the cover, not only can the sealing effect on the liquid outlet be further improved, but the movement of the cover can also be restricted to a certain extent. A gap is provided between the lower surface of the pressing end and the cover body, so that there is a movable stroke between the lower surface of the pressing end and the cover body. When it is necessary to remove the sealing plug from the liquid outlet, pressing the pressing end downward causes the sealing plug to tilt upward, so that the cover can be unrestricted and slide with the cover connecting seat to the position of exposing the liquid outlet.

[0012] In one embodiment, the first end of the cover is provided with a hook protruding relative to the lower surface. The hook is located at the outer end of the sealing block. In the first position, the hook can hook onto the edge of the cover body, thereby restricting the sliding of the cover connecting seat. When moving from the first position to the second position, the hook can follow the first end of the cover and tilt upwards, thereby disengaging from the cover body.

[0013] In these embodiments, when the sealing plug is blocking the liquid outlet, it can restrict the movement of the cover. The hook is located on the outer end of the sealing plug and hooks onto the edge of the cover body in the first position, thereby further ensuring that the cover will not continue to move in this state. This ensures the reliability of the sealing plug in blocking the liquid outlet and avoids the liquid outlet being opened due to misoperation, thus avoiding liquid leakage or the danger of being burned by hot liquid leakage. When preparing to move from the first position to the second position, the hook can follow the first end of the cover and tilt upwards, thereby disengaging from the cover body to ensure that it does not affect the subsequent movement of the cover.

[0014] In one embodiment, the upper surface of the cover body is recessed downward to form an installation groove, the installation groove is offset from the liquid outlet, the side wall of the installation groove is provided with a sliding guide groove, the two sides of the cover plate connecting seat are slidably disposed in the sliding guide groove, and the cover body also includes a limiting part for limiting the sliding range of the cover plate connecting seat between the first position and the second position.

[0015] In these embodiments, the cover plate connector is slidably disposed on both sides within the sliding guide groove, enabling the cover plate connector to slide along the surface of the cover body. This method is simple and the structure is straightforward. A limiting portion is formed between the cover plate connector and the mounting groove to restrict the sliding range of the cover plate connector between a first position and a second position. This prevents the cover plate connector from detaching from the cover body and also indicates the sliding position of the cover plate connector to the user.

[0016] Specifically, the cover plate connecting seat is movable in the length direction of the mounting groove and can be restricted on two side walls in the length direction of the mounting groove, the two side walls in the length direction serving as the limiting part, and the extension length of the mounting groove is equal to the distance between the first position and the second position.

[0017] In one embodiment, the cover plate connector includes a connector body and elastic buckles formed on both sides of the connector body. The elastic buckles are elastically installed in the sliding guide groove and can slide in the sliding guide groove.

[0018] In these embodiments, the resilient snap-fit ​​enhances the ease of installation of the cover connector and the cover body, facilitating disassembly, replacement, or cleaning.

[0019] In one embodiment, the elastic buckle includes a plurality of spaced-apart claw buckles. Each claw buckle includes a support foot protruding downward from the lower surface of the connector body and a protrusion protruding outward from the bottom of the support foot. The protrusion is slidably disposed in the sliding guide groove, and the support foot suspends the connector body in the mounting groove.

[0020] In these embodiments, the protrusion is slidably disposed in the sliding guide groove, thereby ensuring the sliding of the cover plate connector. The support foot suspends the connector body in the mounting groove, resulting in a smaller contact area between the cover plate connector and the cover body, thereby reducing the sliding resistance during sliding and making the sliding of the cover plate connector smoother.

[0021] In one embodiment, the cover plate and the cover plate connecting seat are rotatably connected by a pivot shaft, the pivot shaft being disposed between the first end of the cover plate and the pressing end, the sealing retaining part being located between the first end of the cover plate and the pivot shaft and applying a downward pulling force to the first end of the cover plate, or the sealing retaining part being located between the second end of the cover plate and the pivot shaft and applying an upward pushing force to the second end of the cover plate.

[0022] In one embodiment, one end of the cover plate connecting seat is connected to a mounting base, the lower surface of the cover plate is formed with a receiving groove, the upper end of the sealing retaining part is disposed in the receiving groove, and the lower end of the sealing retaining part is disposed in the mounting base.

[0023] In these embodiments, corresponding components are formed on the cover plate connector and the cover plate to install the sealing retainer, which ensures the installation stability of the sealing retainer.

[0024] In one embodiment, the sealing retainer is a spring, and the mounting base includes a support plate extending outward from one end of the cover plate connecting base and a guide protrusion protruding relative to the upper surface of the support plate. The lower end of the spring is supported on the support plate and sleeved on the guide protrusion. And / or the bottom wall of the receiving groove is formed with a relatively protruding guide rod, and the upper end of the spring abuts against the bottom wall of the receiving groove and is sleeved on the guide rod.

[0025] In these embodiments, the sealing retainer is a spring, and the mounting base or receiving groove is provided to ensure that the spring does not disengage or become misaligned due to the extension and contraction movement, ensuring its reliability during reciprocating movement, thereby enabling the spring to more reliably block the liquid outlet in the first position and ensure the sealing effect.

[0026] Specifically, the upper surface of the cover plate connecting seat has a relatively protruding pivot seat, the pivot seat has a shaft hole, the lower surface of the cover plate has the pivot shaft, and the pivot shaft is rotatably disposed in the shaft hole.

[0027] In one embodiment, the cover plate is an arc-shaped plate, the two ends of which can be tilted upward relative to the middle. The cover plate connecting seat is provided with a baffle rib protruding relative to the upper surface. The baffle rib stops between the cover plate and the cover plate connecting seat and is disposed opposite to the sealing retaining part about the pivot axis.

[0028] In these embodiments, when the cover moves from the first position to the second position, the first end of the cover is released, and the spring force of the spring installed between the cover connecting seat and the pressing end will cause the second end of the cover (pressing end) to be pushed upward, and the first end of the cover to be supported downward on the cover connecting seat. In order to prevent the first end of the cover from drooping significantly due to this spring force, a baffle is provided between the first end of the cover and the cover connecting seat. The baffle supports the cover between the cover and the cover connecting seat, thereby preventing the spring from shifting or disengaging due to a large drop at one end.

[0029] According to a second aspect of this application, a cup is provided, the cup comprising the cup lid described above. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0045] The specific embodiments of this application are described in detail below. Although some embodiments have been shown and described, those skilled in the art should understand that modifications and improvements can be made to these embodiments without departing from the principles and spirit of this application as defined by the claims and their equivalents.

[0046] Embodiments according to this application will now be described in detail with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same reference numerals always denote the same components.

[0047] Below, we will refer to Figures 1 to 6 To describe in detail the composition of the cup lid according to this application.

[0048] According to an embodiment of the first aspect of this application, a cup lid is provided for attaching to a cup body to seal the rim of the cup. In an exemplary embodiment, the cup lid is a lid for a water cup. Figures 1 to 3 As shown, the cup lid includes a lid body 10, a lid connecting seat 20, a lid 30, and a sealing retaining part 40. The upper surface of the lid body 10 is provided with a liquid outlet 11. The lid connecting seat 20 is slidably disposed on the surface of the lid body 10 and can move relative to the liquid outlet 11. The lid 30 is used to cover the liquid outlet 11, is rotatably disposed on the upper surface of the lid connecting seat 20, and can move together with the lid connecting seat 20. The sealing retaining part 40 is disposed between the lid connecting seat 20 and the lid 30 and can apply a force to the lid 30 to block the liquid outlet 11.

[0049] According to the cup lid provided in this application embodiment, the lid connecting seat 20 is slidably disposed on the surface of the lid body 10, and the lid 30 is rotatably connected to the upper surface of the lid connecting seat 20, so that the lid 30 can move together with the lid connecting seat 20 relative to the liquid outlet 11. When drinking water is needed, the lid 30 and the lid connecting seat 20 are moved together and relatively away from the liquid outlet 11 by external force, so that the lid 30 can open the liquid outlet 11; when drinking water is not needed, the lid 30 and the lid connecting seat 20 are moved together and relatively closer to the liquid outlet 11 by external force, so that the liquid outlet 11 can be sealed with the cooperation of the sealing retaining part 40. According to the cup lid of this application, the structure of the cup lid can be simplified while ensuring normal drinking function, thereby simplifying the use and operation of the cup lid and reducing the manufacturing difficulty of the cup lid. Furthermore, due to the provision of the sealing retaining part 40, the lid 30 is sealed at the liquid outlet 11 under the action of the sealing retaining part 40, thereby improving the sealing effect of the cup with this cup lid.

[0050] According to this application, the sealing retaining part 40 can apply a force to the cover plate 30, causing one end of the cover plate 30 to block the liquid outlet 11 downwards. In some embodiments, the sealing retaining part 40 is an elastic member disposed between the cover plate connecting seat 20 and the cover plate 30. In an exemplary embodiment, the elastic member can be a spring. In other embodiments, the sealing retaining part 40 includes a first magnet disposed on the cover plate connecting seat 20 and a second magnet disposed on the cover plate 30. In an exemplary embodiment, the magnet can be a permanent magnet, and the cover plate connecting seat 20 and the cover plate 30 are respectively provided with grooves for mounting the magnets. The first magnet is embedded in the cover plate connecting seat 20, and the second magnet is embedded in the cover plate 30. The possible structural forms of the sealing retaining part 40 have been described above, and the specific installation position of the sealing retaining part 40 and its function on the cover plate 30 will be described in detail in the following embodiments.

[0051] In one embodiment, the cover plate connecting seat 20 is located on the upper surface of the cover body 10 and can slide along the upper surface of the cover body 10 between a first position and a second position. In an exemplary embodiment, in the first position, the cover plate connecting seat 20 is relatively close to the liquid outlet 11, and in the second position, the cover plate connecting seat 20 is relatively far away from the liquid outlet 11. In the first position, the cover plate 30 can be sealed in the liquid outlet 11 by the sealing retaining part 40, and can also be flipped outward under the action of external force to disengage from the liquid outlet 11, thereby sliding with the cover plate connecting seat 20 to the second position to expose the liquid outlet 11, thus allowing drinking or pouring water. Preferably, in the second position, the cover plate 30 can be completely offset from the liquid outlet 11, so that the liquid outlet 11 can be fully exposed, facilitating drinking water for the user.

[0052] like Figure 1 , Figure 3 and Figure 6 As shown, the middle part of the cover plate 30 is rotatably connected to the cover plate connecting seat 20. The first end of the cover plate 30 is used to cover the liquid outlet 11. The second end of the cover plate 30 extends toward the opposite side of the liquid outlet 11 and serves as a pressing end. The first end of the cover plate 30 is provided with a sealing plug 31 protruding relative to the lower surface. In the first position, there is a certain gap between the lower surface of the pressing end and the top of the cover body 10, so that the pressing end can have a certain downward movement. When the pressing end is pressed down, the first end of the cover plate 30 tilts upward, so that the sealing plug 31 can be disengaged from the liquid outlet 11 and slide with the cover plate connecting seat 20 to the second position, so that the liquid outlet 11 is exposed.

[0053] In these embodiments, by providing a relatively protruding sealing plug 31 on the lower surface of the first end of the cover plate 30, not only can the sealing effect on the liquid outlet 11 be further improved, but the lateral movement of the cover plate 30 can also be restricted to a certain extent. A gap is provided between the lower surface of the pressing end and the cover body 10, so that the pressing end can move downward a certain distance. When it is necessary to remove the sealing plug 31 from the liquid outlet 11, pressing the pressing end downward causes the sealing plug 31 to tilt upward along with the first end of the cover plate 30, so that the cover plate 30 can be unrestricted and slide with the cover plate connecting seat 20 to the position where the liquid outlet 11 is exposed.

[0054] In this embodiment, the first end of the cover plate 30 is provided with a downward protruding hook 32. The hook 32 is located at the outer end of the sealing plug 31. In the first position, the hook 32 can hook the edge of the cover body 10, thereby restricting the sliding of the cover plate connecting seat 20. When preparing to move from the first position to the second position, the hook 32 can follow the first end of the cover plate 30 to tilt upward, thereby disengaging from the cover body 10.

[0055] In these embodiments, when the sealing plug 31 blocks the liquid outlet 11, it can restrict the movement of the cover 30. The hook 32 is located at the outer end of the sealing plug 31 and hooks the edge of the cover body 10 in the first position, thereby further ensuring that the cover 30 will not continue to move in this state. This ensures the reliability of the sealing plug 31 in blocking the liquid outlet 11 and avoids the liquid outlet 11 being opened due to misoperation, thereby avoiding liquid leakage or the danger of being burned by hot liquid leakage. When preparing to move from the first position to the second position, the hook 32 can follow the first end of the cover 30 and tilt upwards, thereby disengaging from the cover body 10 to ensure that it does not affect the subsequent movement of the cover 30.

[0056] like Figure 1 , Figure 3 and Figure 4 As shown, the upper surface of the cover body 10 is recessed downwards to form a mounting groove 12. The mounting groove 12 is offset from and spaced apart from the liquid outlet 11. The side wall of the mounting groove 12 is provided with a sliding guide groove 121 extending in a generally horizontal direction. The two sides of the cover plate connecting seat 20 are slidably disposed in the sliding guide groove 121, thereby enabling the cover plate connecting seat 20 to slide on the cover body 10. The cover body 10 also includes a limiting part, which is used to limit the sliding range of the cover plate connecting seat 20 between a first position and a second position.

[0057] In these embodiments, the cover plate connector 20 is slidably disposed on both sides in the sliding guide groove 121, which enables the cover plate connector 20 to slide along the cover body 10. This method is simple and the structure is simple. A limiting part is formed between the cover plate connector 20 and the mounting groove 12, which limits the sliding range of the cover plate connector 20 to between the first position and the second position. On the one hand, this can prevent the cover plate connector 20 from falling off the cover body 10, and on the other hand, it can also indicate the sliding position of the cover plate connector 20 to the user.

[0058] In the embodiment, the cover plate connecting seat 20 is movable in the length direction of the mounting groove 12 and can be restricted on the two side walls in the length direction of the mounting groove 12, which serve as the aforementioned limiting part. The extension length of the mounting groove 12 is equal to the distance between the first position and the second position.

[0059] In these embodiments, the two sidewalls along the length of the mounting groove 12 are used as limiting parts to restrict the sliding of the cover plate connecting seat 20. No additional limiting structure is required, the structure is simple and easy to manufacture.

[0060] like Figure 1 , Figure 3 and Figure 5As shown, the cover plate connecting seat 20 is detachably connected to the cover body 10, including the connecting seat body 21 and elastic buckles 22 formed on both sides of the connecting seat body 21. The elastic buckles 22 are elastically installed in the sliding guide groove 121 and can slide in the sliding guide groove 121.

[0061] In these embodiments, the resilient snap 22 can improve the ease of installation of the cover connector 20 and the cover body 10, and facilitate disassembly, replacement or cleaning.

[0062] Specifically, the elastic buckle 22 includes a plurality of spaced-apart claws, which are generally L-shaped. In an exemplary embodiment, each claw includes a support foot 221 protruding downward from the lower surface of the connecting seat body 21 and a protrusion 222 protruding outward from the bottom of the support foot 221. The protrusion 222 is slidably disposed in the sliding guide groove 121, thereby ensuring the sliding of the cover connecting seat 20. The support foot 221 suspends the connecting seat body 21 in the mounting groove 12, resulting in a smaller contact area between the cover connecting seat 20 and the cover body 10, thereby reducing the sliding resistance during sliding and making the sliding of the cover connecting seat smoother. Of course, the example of the elastic buckle 22 according to this application is not limited to this, and those skilled in the art can choose other modified structures under the teachings of this application.

[0063] In these embodiments, during installation, multiple claw buckles are elastically pressed into the sliding guide groove 121, which enables the cover plate connector 20 to be detachably installed on the cover body 10. The structure is simple and the installation and disassembly are convenient.

[0064] In this embodiment, one end of the cover plate connecting seat 20 is connected to the mounting seat 25. Specifically, a relatively protruding mounting seat 25 is formed at the first end of the connecting seat body 21 in the length direction. A receiving groove 34 is formed on the lower surface of the cover plate 30, the upper end of the sealing retaining part 40 is disposed in the receiving groove 34, and the lower end of the sealing retaining part 40 is disposed in the mounting seat 25.

[0065] In these embodiments, corresponding structures are formed on the cover plate connector 20 and the cover plate 30 respectively to install the sealing retainer 40, which can ensure the installation stability of the sealing retainer 40.

[0066] In this embodiment, the sealing retainer 40 is a spring, and the mounting base 25 includes a support plate 251 extending outward from one end of the connecting base body 21 and a guide protrusion 252 protruding relative to the upper surface of the support plate 251. The lower end of the spring is supported on the support plate 251 and sleeved on the guide protrusion 252; and / or the bottom wall of the receiving groove 34 has a relatively protruding guide rod 341, and the upper end of the spring abuts against the bottom wall of the receiving groove 34 and is sleeved on the guide rod 341. Alternatively, the guide protrusion 252 can be replaced by a groove, so that the lower end of the spring is embedded in the groove.

[0067] In these embodiments, the sealing retainer 40 is a spring, and the mounting base 25 or the receiving groove 34 can ensure that the spring does not disengage or become misaligned due to the extension and retraction movement, ensuring its reliability during reciprocating movement, so that the spring can more reliably block the liquid outlet 11 in the first position and ensure the sealing effect.

[0068] According to this application, the sealing retainer 40 can be installed between the cover plate connecting seat 20 and the cover plate 30. The cover plate 30 is rotatably connected to the upper surface of the cover plate connecting seat 20 via a pivot shaft 331. Taking the pivot shaft 331 as a dividing line, the sealing retainer 40 can be disposed on either side of the pivot shaft 331. In some embodiments, the sealing retainer 40 is disposed between the pivot shaft 331 and the liquid outlet 11, so that when the liquid outlet 11 is blocked, the sealing retainer 40 applies a pulling force to the first end of the cover plate 30. In other embodiments, the sealing retainer 40 is disposed between the pivot shaft 331 and the pressing end, so that when the liquid outlet 11 is blocked, the sealing retainer 40 applies a pushing force to the second end of the cover plate 30, thereby pressing the first end of the cover plate 30 against the liquid outlet 11.

[0069] In an exemplary embodiment, the sealing and retaining part 40 includes a first magnet disposed on the cover plate connecting seat 20 and a second magnet disposed on the cover plate 30. When the sealing and retaining part 40 applies a pulling force to the first end of the cover plate 30, the first magnet and the second magnet have opposite magnetic properties. When the sealing and retaining part 40 applies a pushing force to the first end of the cover plate 30, the first magnet and the second magnet have the same magnetic properties. By utilizing the magnetic attraction principle to seal the liquid outlet 11, the tightness of the seal on the liquid outlet 11 can be achieved by controlling the magnitude of the magnetic attraction force, and the structure is simple.

[0070] In an exemplary embodiment, the cover plate 30 and the cover plate connecting seat 20 are rotatably connected by a pivot shaft 331, which is disposed between the first end of the cover plate 30 and the pressing end. The sealing retaining part 40 is a spring, which is installed between the cover plate connecting seat 20 and the pressing end and applies an outward flipping elastic force to the pressing end, thereby causing the first end of the cover plate 30 to be squeezed inward and close the liquid outlet 11.

[0071] Specifically, a relatively protruding pivot seat 23 is formed on the upper surface of the cover plate connecting seat 20, and a shaft hole 231 is formed in the pivot seat 23. A pivot shaft 331 is formed on the lower surface of the cover plate 30, and the pivot shaft 331 is rotatably disposed in the shaft hole 231, thereby allowing the cover plate 30 to be rotatably disposed on the upper surface of the cover plate connecting seat 20. (See attached...) Figure 6 In the example shown, two downwardly extending lugs 33 are formed on the bottom wall of the cover plate 30, and two pivot shafts 331 are formed on the opposite side walls of the two lugs 33. A handle portion 35 is formed on the surface of the pressing end of the cover plate 30, which can assist in pressing and facilitate the user's pressing operation.

[0072] like Figure 1 , Figure 3 and Figure 5 As shown, the first end of the cover plate 30 is used to cover the liquid outlet 11, and the second end of the cover plate 30 extends toward the opposite side of the liquid outlet 11 and serves as a pressing end. In an exemplary embodiment, the cover plate 30 is an arc-shaped plate, and both ends of the arc-shaped plate can be tilted upward relative to the middle. Specifically, the first end of the arc-shaped plate can cover the liquid outlet 11, the second end of the arc-shaped plate serves as the pressing end mentioned above, and the pivot shaft 331 is formed in the middle of the arc-shaped plate. The cover plate connecting seat 20 is provided with a baffle 24 protruding relative to the upper surface. The baffle 24 stops between the cover plate 30 and the cover plate connecting seat 20, and is disposed opposite to the sealing retaining part 40 about the pivot shaft 331, thereby supporting it between the first end of the cover plate 30 and the cover plate connecting seat 20.

[0073] In these embodiments, when the cover plate 30 moves from the first position to the second position, the first end of the cover plate 30 is released, and the spring force of the spring installed between the cover plate connecting seat 20 and the pressing end will cause the second end of the cover plate (pressing end) to be pushed upward, and the first end of the cover plate 30 to be supported downward on the cover plate connecting seat. In order to prevent the first end of the cover plate 30 from drooping significantly due to this spring force, a baffle 24 is provided between the first end of the cover plate 30 and the cover plate connecting seat 20. The baffle 24 supports the cover plate 30 between the cover plate 30 and the cover plate connecting seat 20, thereby preventing the spring from shifting or disengaging due to a large drop at one end.

[0074] When using a cup with a lid according to this application, when it is necessary to open the liquid outlet 11, the pressing end is pressed down, the spring is compressed, and the sealing plug 31 is lifted up and disengaged from the liquid outlet 11. In this case, the lid 30 is pulled outward, so that the lid 30 and the lid connecting seat 20 move away from the liquid outlet 11. When it is necessary to close the liquid outlet 11, the lid 30 is pushed inward, so that the lid 30 and the lid connecting seat 20 move close to the liquid outlet 11, and the sealing plug 31 can enter the liquid outlet 11 and be held in the state of sealing the liquid outlet 11 by the action of the sealing retaining part 40.

[0075] According to a second aspect of this application, a cup is provided, which includes the cup lid provided in the above embodiments and thus has all the beneficial effects of the above embodiments, which will not be discussed one by one here.

[0076] In one embodiment, the cup also includes a cup body and a cup lid, with the cup lid disposed at the mouth of the cup body to seal the mouth of the cup body.

[0077] In one embodiment, the lid body 10 of the cup lid is provided with threads, and the cup body is threadedly connected to the lid body 10.

[0078] In this embodiment, the cup also includes a water-resistant sealing ring 50, which is disposed at the connection between the cup body and the cup lid.

[0079] While embodiments of this application have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of this application without departing from the spirit and scope of this application. However, it should be understood that, in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of this application as defined in the claims.
