Cup cover and cup

Abstract

The application relates to a cup cover and a cup. The cup cover comprises a cover body, a sealing assembly arranged at least partially below the cover body, and a sliding piece arranged at least partially above the cover body. The cover body is provided with a water outlet. The sealing assembly comprises a sealing body and a connecting part connected to one side of the sealing body. The connecting part is rotationally connected to the cover body, so that the sealing body can be rotated downward to open the water outlet or rotated upward to cover the water outlet. The sliding piece is arranged to slide back and forth between an opening position and a blocking position, so as to drive the sealing assembly to rotate upward or downward relative to the cover body. When the sliding piece is in the blocking position, the sealing body blocks the water outlet from below. When the sliding piece is in the opening position, there is a gap between the sealing body and the water outlet, so as to open the water outlet. By rotationally connecting the sealing assembly to the cover body below, the sealing body blocks the water outlet from below. The sealing mode utilizes the steam pressure generated by hot drinks in the cup body to push the sealing body to the water outlet, thereby enhancing the sealing effect on the water outlet.

Description

Technical Field

[0001] This application relates to the technical field of liquid containers, and in particular to a cup lid and a cup. Background Technology

[0002] For cups with lids, designers have created various lids with opening structures to allow users to drink directly from the liquid without opening the lid. Among them, the push-plate structure has received widespread attention due to its ease of use. Users do not need to unscrew the entire lid; they only need to push or press a specific part to open the drinking spout, making it particularly suitable for use in mobile or busy situations.

[0003] However, most of the push-tab sealing structures commonly used in cup lids currently employ a single elastic element or a simple snap-fit ​​method. While they can maintain a basic seal at room temperature, under heated conditions, due to the steam pressure generated by the hot beverage itself, the thermal expansion effect of the cup lid caused by the hot beverage transferring heat to the cup lid, material deformation, structural gaps, or poor sealing surface fit, existing push-tab cup lids have significant sealing problems when sealing hot beverages, which in turn leads to hot beverages easily leaking or seeping from the drinking spout. Utility Model Content

[0004] Therefore, it is necessary to provide a method to improve the sealing effect of the spout on the cup lid when hot drinks are poured into the cup.

[0005] A cup lid, comprising:

[0006] The cover has a water outlet that penetrates the cover along its height.

[0007] A sealing assembly, at least partially disposed below the cover, includes a sealing body and a connecting portion connected to one side of the sealing body. The connecting portion is rotatably connected to the cover so that the sealing body can rotate downward to open the water outlet or rotate upward to cover the water outlet.

[0008] A slider, at least partially disposed above the cover, is arranged to slide back and forth along the upper surface of the cover between an open position and a closed position, thereby causing the sealing assembly to rotate up and down relative to the cover.

[0009] When the sliding member is in the blocked position, the sealing body blocks the water outlet from below and seals with the cover; when the sliding member is in the open position, a gap is left between the sealing body and the water outlet to open the water outlet.

[0010] In one embodiment, the direction from the blocking position to the opening position is defined as a first direction. The sliding member is linked with the sealing body through an extension and a snap-fit ​​portion. The extension is provided on one of the sliding member and the sealing body, and the snap-fit ​​portion is provided on the other of the sliding member and the sealing body. The extension is inclined upward along the first direction, and the snap-fit ​​portion is slidably constrained to the extension along the extension direction of the extension.

[0011] In one embodiment, the sealing body includes a protrusion near the slider, the protrusion being able to pass through the water outlet; an extension is provided on the protrusion, and the extension is a groove formed by recessing inward from the side wall of the protrusion; a snap-fit ​​portion is provided on the lower surface of the slider, and the end of the snap-fit ​​portion away from the slider is inserted into the groove.

[0012] In one embodiment, the cup lid further includes a first limiting portion, which is used to stop the slider in the blocking position when the slider is in the blocking position.

[0013] In one embodiment, the first limiting part protrudes from the bottom surface of the groove. When the sliding member is in the blocking position, the first limiting part stops on one side of the locking part to restrict the sliding member from leaving the blocking position along the first direction.

[0014] In one embodiment, the cup lid further includes a second limiting portion for stopping the slider in the open position. The second limiting portion protrudes from the bottom surface of the groove, and the first limiting portion and the second limiting portion are arranged at intervals along the first direction. When the slider is in the open position, the locking portion is located on the side of the second limiting portion away from the first limiting portion, thereby enabling the second limiting portion to restrict the slider from leaving the open position in the opposite direction of the first direction.

[0015] In one embodiment, the cover has a slot extending in a first direction, and the slider includes a claw that can be inserted into the slot and slide within the slot.

[0016] In one embodiment, the cup lid further includes a third limiting part protruding into the slot. The third limiting part is disposed on the movement path of the claw. When the slider is in the blocking position, the third limiting part and the claw are arranged in the opposite direction of the first direction. The third limiting part stops on one side of the claw to restrict the slider from leaving the blocking position along the first direction.

[0017] In one embodiment, the direction from the sealing position to the opening position is defined as a first direction, the sealing body and the connecting portion are arranged along the first direction, and the end of the connecting portion away from the sealing body is rotatably connected to the cover via a connecting shaft.

[0018] In one embodiment, the sealing body includes a baffle connected to the connecting portion and an elastic ring sleeved on the outer periphery of the baffle. When the sliding member is in the blocking position, the elastic ring surrounds the outer periphery of the outlet and seals with the cover.

[0019] In one embodiment, at least a portion of the sidewall of the baffle is provided with a mounting portion extending circumferentially along the baffle, and the inner peripheral wall of the elastic ring is recessed inward to form a mounting groove, and the mounting portion is engaged in the mounting groove.

[0020] In one embodiment, the connecting portion is connected to the side wall of the baffle, the mounting portion is configured as an annular structure with an opening, the mounting portion is arranged around the baffle, and both ends of the mounting portion are connected to the connecting portion; the elastic ring is provided with a clearance portion to avoid the connecting portion.

[0021] In one embodiment, the cover extends downward at the peripheral wall of the outlet to form an extension ring, and when the slider is in the blocking position, the elastic ring abuts against the extension ring.

[0022] This application also provides a cup, including a cup body and a cup lid mounted on the cup body, the cup lid being the cup lid as described in any of the preceding embodiments.

[0023] Compared with existing technologies, the cup lid provided in this application, by rotatably connecting the sealing component to the bottom of the lid body, allows the sealing body to rotate upward and tightly fit against the spout when the sliding member slides from the open position to the sealed position, thus blocking the spout from below the lid body. When the cup lid is installed on the cup body, this sealing method utilizes the steam pressure generated by the hot beverage in the cup body to further push the sealing body towards the spout, thereby enhancing the sealing effect of the sealing component on the spout.

[0024] Compared with the prior art, in the cup lid provided in this application, when the sliding member moves from the open position to the closed position, it can drive the sealing body in the sealing assembly to rotate upward to block the water outlet from below the lid body and seal with the lid body. That is to say, when the sliding member is in the closed position, the force applied to the sealing body by the sliding member and the lid body can physically compress the sealing body to form a sealing structure between the sealing body and the water outlet of the lid body. When the cup lid is installed on the cup body, this sealing structure not only provides a reliable seal for the water outlet at room temperature, but also, under heated conditions, this sealing method can use the steam pressure generated by the hot beverage in the cup body to push the sealing body further towards the water outlet, thereby enhancing the sealing effect of the sealing assembly on the water outlet of the lid body. Moreover, in this embodiment, the sealing body is driven by the sliding member to rotate up and down. Therefore, when the sliding member is in the closed position, it can ensure the stability of the pressure on the sealing surface between the sealing body and the lid body, thereby ensuring the sealing effect of the sealing assembly on the water outlet of the lid body.

[0054] Please see Figures 1 to 22 This application provides a cup lid 10, including a lid body 11, a sealing assembly 12, and a sliding member 13. The lid body 11 has a through-hole 1101 along its height direction (see reference). Figure 2 and Figure 3 At least a portion of the sealing assembly 12 is located below the cover 11. The sealing assembly 12 includes a sealing body 121 and a connecting portion 122 connected to one side of the sealing body 121. The connecting portion 122 is rotatably connected to the cover 11, allowing the sealing body 121 to rotate downwards to open the outlet 1101 or rotate upwards to cover the outlet 1101. At least a portion of the sliding member 13 is located above the cover 11 and is arranged to slide back and forth along the upper surface of the cover 11 between an open position and a closed position, thereby driving the sealing assembly 12 to rotate up and down relative to the cover 11. When the sliding member 13 is in the closed position, the sealing body 121 covers the outlet 1101 from below and seals against the cover 11. When the sliding member 13 is in the open position, a gap is left between the sealing body 121 and the outlet 1101 to open the outlet 1101.

[0055] It is understood that in this embodiment, when the sliding member 13 moves from the open position to the closed position, it can drive the sealing body 121 in the sealing assembly 12 to rotate upwards to block the water outlet 1101 from below the cover 11 and seal with the cover 11. That is, when the sliding member 13 is in the closed position, the force applied to the sealing body 121 by the sliding member 13 and the cover 11 can physically compress the sealing body 121 to form a sealing structure between the sealing body 121 and the water outlet 1101 of the cover 11. When the cup lid 10 is installed on the cup body 20, this sealing structure can not only provide a reliable seal for the water outlet 1101 at room temperature, but also, under heated conditions, this sealing method can use the steam pressure generated by the hot beverage in the cup body 20 to further push the sealing body 121 towards the water outlet 1101, thereby enhancing the sealing effect of the sealing assembly 12 on the water outlet 1101 of the cover 11. Furthermore, in this embodiment, the sealing body 121 is driven by the sliding member 13 to rotate up and down. When the sliding member 13 is in the blocking position, it can ensure the stability of the pressure on the sealing surface between the sealing body 121 and the cover 11, thereby ensuring the sealing effect of the sealing assembly 12 on the water outlet 1101 on the cover 11.

[0056] Meanwhile, even if the cover 11 or the sealing body 121 changes size due to thermal expansion, the sealing fit between the sealing body 121 and the cover 11 can maintain sufficient pressure of the sealing body 121 on the outlet 1101 of the cover 11. That is, the sealing fit between the sealing body 121 and the cover 11 compensates for the gap change between the sealing body 121 and the cover 11 caused by thermal expansion, so that the sealing surface between the sealing body 121 and the outlet 1101 always remains tight, thereby preventing liquid leakage.

[0057] Indicatively, the sealing body 121 and the cover 11 are interference-fitted, thereby achieving a sealing fit between the sealing body 121 and the cover 11.

[0058] It is also understood that in this embodiment, when the sliding member 13 slides from the blocking position to the opening position, it can drive the sealing body 121 in the sealing assembly 12 to rotate downward, and a gap is generated between the sealing body 121 and the cover 11. At this time, the liquid in the cup 20 can enter and exit the cup 20 from the outlet 1101, that is, the outlet 1101 is opened.

[0059] In one embodiment, see Figures 4-17 , Figure 21 and Figure 22The direction from the sealing position to the opening position is defined as the first direction X. The sliding member 13 is linked with the sealing body 121 through the extension 14 and the locking part 15. The extension 14 is provided on one of the sliding member 13 and the sealing body 121, and the locking part 15 is provided on the other. The extension 14 is inclined upward along the first direction X, and the locking part 15 is slidably constrained to the extension 14 along the extension direction of the extension 14. It can be understood that when the sliding member 13 slides back and forth between the sealing position and the opening position, there will be relative movement between the extension 14 and the locking part 15. Since the extension 14 is inclined upward along the first direction X, there will also be relative movement in the vertical direction between the extension 14 and the locking part 15. Thus, when the sliding member 13 slides back and forth between the sealing position and the opening position, it can drive the sealing assembly 12 to rotate relative to the vertical direction, thereby sealing or opening the outlet 1101. It should be noted that the first direction X is parallel or substantially parallel to the upper surface of the cover 11.

[0060] Indicative, the following text will use... Figures 4-8 , Figures 11-15 The illustrated embodiment, specifically with the extension 14 disposed on the sealing body 121, will be explained as an example. It should be noted that... Figure 4 , Figure 6 , Figure 11 and Figure 13 The first direction X in the diagram is from left to right. When the slider 13 is in the blocking position (see...), Figure 4 and Figure 5 The snap-fit ​​portion 15 is located at the lower part (i.e., the bottom end) of the extension portion 14. Figure 7 (the leftmost end of the middle), while when the slider 13 is in the open position (see the leftmost end of the middle), and when the slider 13 is in the open position (see the leftmost end of the middle ... Figure 11 and Figure 12 The snap-fit ​​portion 15 is located at the high point of the extension portion 14 (i.e., the top). Figure 14 (The rightmost end of the middle). So, during the process of the sliding member 13 moving from the sealed position to the open position, that is, when the sliding member 13 slides relative to the cover 11 along the first direction X, the engaging part 15 will move relative to the extension 14 along the first direction X, that is, from the left end of the extension 14 to the right end of the extension 14. Since the extension 14 is inclined upwards along the first direction X, that is, the shortest distance between the left end of the extension 14 and the sliding member 13 is greater than the shortest distance between the right end of the extension 14 and the sliding member 13, during the movement of the engaging part 15 from left to right, since the length of the engaging part 15 is fixed, the engaging part 15 can push the extension 14 downwards, thereby causing the sealing body 121 to disengage from the sealed engagement state with the cover 11, that is, a gap appears between the sealing body 121 and the cover 11, which opens the water outlet 1101 on the cover 11 (see reference). Figure 15 The process of the sliding member 13 moving from the open position to the sealed position is the reverse of the above process. The sliding member 13 slides in the opposite direction of the first direction X, that is, from right to left. The engaging part 15 will pull the extension part 14 upward until the sealing body 121 and the cover 11 are sealed together, thereby sealing the outlet 1101 (see reference). Figure 8 ).

[0061] This is illustrative; the following explanation uses the example of the extension 14 being provided on the slider 13 as an example. Figure 21 and Figure 22 As shown, when the slider 13 is in the blocking position (see reference...) Figure 21 The snap-fit ​​portion 15 is located at the high point of the extension portion 14 (i.e., the top). Figure 21 (the rightmost end of the middle), and when the slider 13 is in the open position (see the reference). Figure 22 The snap-fit ​​portion 15 is located at the lower part (i.e., the bottom end) of the extension portion 14. Figure 22 (The leftmost end of the middle). So, during the process of the sliding member 13 moving from the blocking position to the opening position, that is, when the sliding member 13 slides relative to the cover 11 along the first direction X, since the extension 14 is provided on the sliding member 13 and the locking part 15 is provided on the sealing body 121, the extension 14 will move relative to the locking part 15 along the first direction X, so that the locking part 15 transitions from the right end of the extension 14 to the left end of the extension 14. Since the shortest distance between the right end of the extension 14 and the sealing body 121 is greater than the shortest distance between the left end of the extension 14 and the sealing body 121, during the process of the extension 14 moving from left to right, the extension 14 will push the locking part 15 downward, thereby creating a gap between the sealing body 121 and the cover 11, that is, opening the water outlet 1101 on the cover 11. The process of the sliding member 13 moving from the open position to the sealed position is the reverse of the above process. The sliding member 13 slides in the opposite direction of the first direction X, that is, from right to left. The extension 14 will pull the locking part 15 upward until the sealing body 121 and the cover 11 are sealed together, thereby sealing the outlet 1101. It should be noted that... Figure 21 and Figure 22 The dashed line in the figure represents the plane where the water outlet 1101 is located.

[0062] In one embodiment, see Figure 10 , Figure 16 , Figure 17 as well as Figure 19The sealing body 121 includes a protrusion 1211 near the sliding member 13, which can pass through the outlet 1101; an extension 14 is provided on the protrusion 1211, and the extension 14 is a groove 1212 formed by recessing inward from the side wall of the protrusion 1211; a snap-fit ​​part 15 is provided on the lower surface of the sliding member 13, and the end of the snap-fit ​​part 15 away from the sliding member 13 is inserted into the groove 1212. It can be understood that the surface area of ​​the sealing body 121 facing the cover 11 is larger than the surface area of ​​the outlet 1101. Through the protrusion 1211 passing through the outlet 1101, the sliding member 13, which is at least partially located above the cover 11, and the sealing body 121, which is at least partially located below the cover 11, can be connected together, so that when the sliding member 13 slides on the upper surface of the cover 11, it can drive the sealing body 121 to rotate up and down below the cover 11.

[0063] In other embodiments, the snap-fit ​​portion 15 can also be inserted through the outlet 1101 to connect the sliding member 13 and the sealing body 121. This application does not limit this, as long as the linkage between the sliding member 13 and the sealing body 121 can be realized.

[0064] In one embodiment, see Figure 7 , Figure 9 , Figure 16 and Figure 19 The cup lid 10 also includes a first limiting part 161. When the sliding member 13 is in the blocking position, the first limiting part 161 is used to stop the sliding member 13 in the blocking position. In this way, when the sliding member 13 is pushed to the blocking position, the sliding member 13 can be locked in the blocking position by the first limiting part 161. At this time, the sealing state between the sealing body 121 and the water outlet 1101 is not affected by the shaking or inversion of the cup body 20. The sealing effect between the sealing body 121 and the water outlet 1101 of the lid 11 is better, and there is no need to worry about liquid leakage inside the cup body 20 when carrying the cup body 20 with the cup lid 10 installed. This makes the cup 100 with the cup lid 10 installed in this embodiment suitable for use in mobile scenarios such as business trips and commuting.

[0065] Furthermore, the first limiting part 161 protrudes from the bottom surface of the slide groove 1212. When the sliding member 13 is in the blocking position, the first limiting part 161 stops on one side of the locking part 15 to restrict the sliding member 13 from leaving the blocking position along the first direction X. It can be understood that the first limiting part 161 is provided in the form of a protrusion on the bottom surface of the slide groove 1212. The first limiting part 161 can act as a mechanical stop point, providing a physical barrier that is difficult to overcome spontaneously for the locking part 15. In this way, it can be ensured that the seal can always be in the blocking position, preventing the sliding member 13 from moving from the blocking position to the open position, thereby preventing the seal from separating from the outlet 1101 of the cover 11 due to downward rotation, improving the sealing effect between the seal and the cover 11, and preventing liquid leakage in the cup body 20 on which the cup cover 10 is installed.

[0066] It should be noted that the opening of the groove 1212 faces the engaging portion 15, so that the end of the engaging portion 15 away from the slider 13 can be inserted into the groove 1212. Here, "bottom surface of the groove 1212" refers to the surface opposite to the opening. It should also be noted that "restricting the slider 13 from disengaging from the blocking position along the first direction X" means that, without the application of external force, the first limiting portion 161 can restrict the slider 13 from disengaging from the blocking position. When the user applies a force along the first direction X to the slider 13, and this force is greater than the resistance of the first limiting portion 161 to the engaging portion 15, the engaging portion 15 can pass over the first limiting portion 161, thereby causing the slider 13 to disengage from the blocking position.

[0067] Understandably, the engaging portion 15 can slide towards the first limiting portion 161 until it abuts against the first limiting portion 161, and it can also slide away from the first limiting portion 161. Figure 7 , Figure 9 and Figure 16 The embodiment in the figure illustrates that the movement direction of the slider 13 is defined as the left-right direction. The blocking position is located at the left end of the cover 11, and the opening position is located at the right end of the cover 11. When the slider 13 is in the blocking position, the locking part 15 is located to the left of the first limiting part 161. At this time, the first limiting part 161 can restrict the locking part 15 to its left side, that is, restrict the slider 13 to the blocking position, preventing the slider 13 from moving from the blocking position to the opening position.

[0068] In one embodiment, see Figure 7 , Figure 9 , Figure 16 , Figure 19The cup lid 10 also includes a second limiting part 162 for stopping the slider 13 in the open position. The second limiting part 162 protrudes from the bottom surface of the slide groove 1212. The first limiting part 161 and the second limiting part 162 are arranged at intervals along the first direction X. When the slider 13 is in the open position, the engaging part 15 is located on the side of the second limiting part 162 away from the first limiting part 161, so that the second limiting part 162 can restrict the slider 13 from leaving the open position in the opposite direction of the first direction X. It can be understood that regardless of whether the slider 13 is in the closed position or the open position, the slider 13 is always arranged side by side with the lid 11 along the thickness direction of the lid 11. When the slider 13 is in the open position, when the user drinks the liquid in the cup body 20 through the water outlet 1101, the cup body 20 needs to be lifted and the axis of the cup body 20 needs to be at a certain angle to the vertical direction. At this time, the sliding direction of the slider 13 will also be at a certain angle to the vertical direction. Since the second limiting part 162 stops on one side of the locking part 15 to restrict the slider 13 from leaving the open position, that is, the second limiting part 162 restricts the slider 13 to the open position. In this way, the slider 13 will not slide from the open position to the blocked position under the action of gravity, so as not to interrupt the user's process of drinking the liquid in the cup body 20.

[0069] It should also be noted that "the second limiting part 162 can restrict the slider 13 from disengaging from the open position in the opposite direction of the first direction X" means that the second limiting part 162 can restrict the slider 13 from disengaging from the open position without the application of external force. When the user applies a force to the slider 13 in the opposite direction of the first direction X, and this force is greater than the resistance of the second limiting part 162 to the locking part 15, the locking part 15 can pass over the second limiting part 162, thereby causing the slider 13 to disengage from the open position.

[0070] In one embodiment, see Figure 2 The cover 11 is provided with a slot 1102 extending along the first direction X. The slider 13 includes a claw 131 that can be inserted into the slot 1102 and slide within the slot 1102. In this way, the slot 1102 can guide the movement direction of the slider 13, preventing the movement direction of the slider 13 from deviating from the first direction X, thereby better driving the movement of the sealing body 121.

[0071] For further information, please refer to... Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 11The upper surface of the lid 11 is recessed downward to form a groove 1103 extending along the first direction X. The slider 13 is constrained in the groove 1103 to slide back and forth between the open position and the closed position. It can be understood that the open position and the closed position are both located in the extending direction of the groove 1103. In this way, the sliding direction of the slider 13 can be guided by the groove 1103, and part of the slider 13 can be hidden in the groove 1103, thereby reducing the overall height of the lid 10. The slot 1102 is provided in the slide groove 1212 and is formed by extending from the inner wall of the slide groove 1212 in a direction away from the slide groove 1212.

[0072] For illustrative purposes only, see below. Figure 10 , Figure 18 Two claws 131 are provided and spaced apart along the second direction Y to make the movement of the slider 13 more balanced. The second direction Y is at an angle to the first direction X and the up and down direction. In the embodiment where the locking part 15 is provided in the slider 13, two locking parts 15 are provided and spaced apart along the second direction Y, and both locking parts 15 are located inside the two claws 131 so that they can pass through the outlet 1101 or be inserted into the extension 14 passing through the outlet 1101.

[0073] In one embodiment, see Figure 2 The cup lid 10 also includes a third limiting part 163 protruding in the slot 1102. The third limiting part 163 is disposed on the movement path of the claw 131. When the slider 13 is in the blocking position, the third limiting part 163 and the claw 131 are arranged in the opposite direction of the first direction X. The third limiting part 163 stops on one side of the claw 131 to restrict the slider 13 from leaving the blocking position along the first direction X. Understandably, the first limiting part 161 limits the locking part 15, thus restricting the sliding member 13 to the sealing position. This is the first level of limiting the sliding member 13. The third limiting part 163 limits the claw 131, which also restricts the sliding member 13 to the sealing position. This is the second level of limiting the sliding member 13. Thus, the sliding member 13 is doubly limited. This can better prevent the sliding member 13 from leaving the sealing position and prevent gaps from forming between the sealing body 121 and the lower surface of the cover 11, thereby further ensuring the sealing effect of the sealing body 121 on the outlet 1101 of the cover 11.

[0074] In one embodiment, the sealing body 121 and the connecting portion 122 are arranged along a first direction X, and the end of the connecting portion 122 away from the sealing body 121 is rotatably connected to the cover 11 via a connecting shaft 123. It can be understood that the end of the water outlet 1101 near the sealing position is the end near the user's lips, i.e., the user's drinking area. Since the sealing body 121 and the connecting portion 122 are arranged along the first direction X, then... Figure 7Taking the embodiment shown as an example, the sealing body 121 is arranged close to the sealing position (corresponding to...) Figure 7 (At the left end of the middle), the connecting part 122 is arranged near the opening position (corresponding to ... Figure 7 (The right end of the middle). Therefore, the sealing body 121 rotates on the side of the connecting shaft 123 away from the open position. It can also be understood that when drinking liquid from the cup 20 through the outlet 1101, the liquid flows out from the aforementioned drinking point. At this time, the connecting shaft 123 and the connecting part 122 are located above the liquid. Thus, when drinking liquid from the cup 20, interference with the flow path of the liquid by the connecting shaft 123 and the connecting part 122 can be avoided.

[0075] In one embodiment, see Figure 8 , Figure 9 and Figure 15 The sealing body 121 includes a baffle 1213 connected to the connecting part 122 and an elastic ring 1214 sleeved on the outer periphery of the baffle 1213. When the sliding member 13 is in the blocking position, the elastic ring 1214 surrounds the outer periphery of the outlet 1101 and seals with the cover 11. It can be understood that in this embodiment, the outlet 1101 is first directly blocked from below the cover 11 by the baffle 1213, and then the elastic ring 1214 surrounds the outer periphery of the outlet 1101, forming an annular seal with the cover 11. The sealing body 121 not only covers the outlet 1101 itself, but also seals the area around the outlet 1101. This not only solves the problem of poor sealing caused by misalignment or thermal deformation of a single pusher, but also minimizes the volume of the sealing body 121 by fitting the elastic ring 1214 around the outer periphery of the baffle 1213. This makes the structure of the cup lid 10 more compact and adaptable to cups 100 of different sizes.

[0076] In illustrative terms, the elastic ring 1214 is made of silicone. Thus, the elastic ring 1214 not only possesses elasticity, allowing for an interference fit with the cover 11 to improve the sealing effect between the elastic ring 1214 and the cover 11, but also has advantages such as high temperature resistance and safety. In other embodiments, the elastic ring 1214 can also be made of wear-resistant plastic or other materials; this application does not limit this, as long as the material is safe and can seal the outlet 1101.

[0077] In one embodiment, see Figure 19At least a portion of the sidewall of the baffle 1213 has a protruding mounting portion 1215 extending circumferentially along the baffle 1213. The inner circumferential wall of the elastic ring 1214 is recessed inward to form a mounting groove 1216, and the mounting portion 1215 is engaged in the mounting groove 1216. In this way, the connection between the baffle 1213 and the elastic ring 1214 is tighter, enabling the baffle 1213 and the elastic ring 1214 to achieve "mechanical interlocking". This allows the baffle 1213 and the elastic ring 1214 to work together as a whole to seal the outlet 1101 of the cover 11, thereby improving the sealing effect of the cover 11 to be better and more reliable.

[0078] Schematic illustration: The mounting portion 1215 extends circumferentially along the baffle 1213. The mounting portion 1215 can be a closed annulus or an open annulus. When the mounting portion 1215 is an open annulus, the mounting groove 1216 inside the elastic ring 1214 can be an annular groove or a non-annular groove with a notch matching the opening of the mounting portion 1215. This application does not limit this and can be adjusted according to the application scenario. It should also be noted that for the elastic ring 1214 with a notch, it is still a closed annulus, only with a notch at the mounting groove 1216. (See reference...) Figure 20 .

[0079] In one embodiment, the connecting portion 122 is connected to the side wall of the baffle 1213, and the mounting portion 1215 is configured as an open annular structure. The mounting portion 1215 surrounds the baffle 1213 and its two ends are connected to the connecting portion 122. The elastic ring 1214 is provided with a clearance portion 1217 to avoid the connecting portion 122. Connecting the connecting portion 122 to the side wall of the baffle 1213 helps to reduce the overall height of the sealing assembly 12, thereby helping to reduce the overall height of the cup lid 10, making the structure of the cup lid 10 more compact.

[0080] In one embodiment, see Figure 8 and Figure 15 The cover 11 extends downwards at the peripheral wall of the outlet 1101 to form an extension ring 111. When the sliding member 13 is in the blocking position, the elastic ring 1214 abuts against the extension ring 111. It can be understood that by setting the extension ring 111, the sealing surface between the elastic ring 1214 and the cover 11 can be raised from a flat plane to a ring-shaped three-dimensional curved surface. When the pressing force of the elastic ring 1214 on the cover 11 is constant, the extension ring 111 can increase the pressure between the elastic ring 1214 and the outlet 1101 of the cover 11. The material on the surface of the elastic ring 1214 can be "squeezed" into the microscopic unevenness on the surface of the extension ring 111, thereby achieving a tighter fit between the elastic ring 1214 and the extension ring 111, and thus improving the sealing effect of the sealing member on the outlet 1101.

[0081] This application also provides a cup 100, which can be referenced. Figure 1The cup 100 includes a cup body 20 and a cup lid 10 as described above, with the cup lid 10 detachably mounted on the cup body 20. By providing the cup lid 10 in any of the above embodiments on the cup 100, not only is dust prevented from accumulating at the spout 1101 of the cup 100, ensuring the cleanliness and hygiene of the cup 100, but it can also be operated with one hand. Specifically, by pushing the slider 13 from the blocked position to the open position with one hand, the spout 1101 can be opened; by pushing the slider 13 from the open position to the blocked position with one hand, the spout 1101 can be closed, making it convenient to use.

[0082] In one embodiment, see Figure 1 The cup lid 10 is also provided with a handle 21, and there is a handle space between the handle 21 and the top surface of the cup lid 10 for a hand to pass through. It can be understood that the user can move and carry the cup 100 through the handle 21, thereby making the cup 100 more portable.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
