Abstract
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 developed 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 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 cup lid and a cup that improve the sealing effect of the spout on the cup lid when hot drinks are contained in the cup.
[0005] A cup lid, comprising:
[0006] The cover has a water outlet that penetrates the cover along its height.
[0007] A switch assembly is slidably disposed on the cover. The switch assembly includes a slider and a seal connected to each other. The slider is at least partially disposed above the cover, and the seal is at least partially disposed below the cover. The seal includes a baffle and a sealing ring. The baffle is connected to the slider, and the sealing ring is sleeved on the baffle. The top surface of the sealing ring is interference-fitted with the cover.
[0008] The sliding member can drive the sealing member to slide back and forth between the open position and the closed position. When the sliding member is in the open position, the sealing member is located next to the water outlet to open the water outlet. When the sliding member is in the closed position, the baffle blocks the water outlet from below, and the sealing ring is arranged around the outer periphery of the water outlet and seals with the cover to block the water outlet.
[0009] In one embodiment, a limiting structure is provided between the cover and the slider to restrict the slider from moving from the blocking position to the opening position.
[0010] In one embodiment, the limiting structure includes a first limiting portion and a second limiting portion that can abut against each other along the movement direction of the slider. The first limiting portion is disposed on the slider, and the second limiting portion is disposed on the cover. When the slider is in the blocked position, the second limiting portion stops on one side of the first limiting portion to restrict the slider from leaving the blocked position. When the slider is in the open position, the second limiting portion stops on the other side of the first limiting portion to restrict the slider from leaving the open position.
[0011] In one embodiment, the first limiting portion protrudes downward on the lower surface of the slider, and the second limiting portion protrudes upward on the upper surface of the cover; and / or, one of the first limiting portion and the second limiting portion is a limiting groove, and the other is a protrusion that can abut against the limiting groove.
[0012] In one embodiment, the upper surface of the cover is recessed downward to form a groove, the slider is constrained in the groove to slide back and forth between the open position and the sealed position, and the second limiting part is provided on the bottom surface of the groove.
[0013] In one embodiment, the sealing ring includes a ring body located on the outer periphery of the baffle and a first extension extending inward from the end of the ring body near the cover body, the top surface of the first extension being higher than the upper surface of the baffle body, so that the first extension and the cover body are in an interference fit.
[0014] In one embodiment, the end of the ring body away from the cover body is provided with an inwardly extending second extension, and an annular groove is formed between the ring body, the first extension and the second extension, the outer periphery of the baffle is clamped in the annular groove, and the second extension abuts against at least a portion of the baffle below.
[0015] In one embodiment, the direction from the open position to the sealed position is defined as a first direction. The cover is also provided with a sliding hole extending along the first direction. The water outlet and the sliding hole are spaced apart along the first direction. When the sliding member switches between the open position and the sealed position, the sealing ring always surrounds the outer periphery of the sliding hole. The switch assembly also includes a connector and a stop. The connector passes through the sliding hole and can slide within the sliding hole along the first direction. The two ends of the connector, which are arranged opposite each other along its own length, are respectively connected to the sliding member and the stop. The stop is located below the seal to prevent the seal from detaching from the connector.
[0016] In one embodiment, the stop member has a threaded hole along the length of the connector, and the outer peripheral side of the connector has an external thread that is threadedly connected to the threaded hole.
[0017] 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.
[0018] Compared with the prior art, the cup lid provided in this application includes a sealing element at least partially located below the lid body, comprising a baffle and a sealing ring, with the sealing ring fitted onto the baffle. When the sliding member is in the blocking position, the baffle blocks the outlet from below, and the sealing ring surrounds the outer periphery of the outlet and seals with the lid body. Since the top surface of the sealing ring is in an interference fit with the lid body, that is, by physically compressing the sealing ring, a sealing structure is formed between the sealing ring and the outlet of the lid body. This interference fit not only provides a reliable seal for the outlet at room temperature, but also, under heated conditions, even if the lid body or sealing ring undergoes dimensional changes due to thermal expansion, the interference fit can maintain sufficient pressure of the sealing ring on the outlet of the lid body. In other words, the interference fit compensates for the gap changes between the sealing element and the lid body caused by thermal expansion, ensuring that the sealing surface between the sealing element and the outlet remains tight, thereby preventing liquid leakage.
[0019] Furthermore, in this embodiment, the spout is first directly blocked from below the lid by a baffle, and then a sealing ring is placed around the outer periphery of the spout, forming a ring seal with the lid. The seal not only covers the spout itself but also seals the area around it. This solves the problem of incomplete sealing caused by misalignment or thermal deformation of a single pusher plate. Moreover, by placing the sealing ring around the outer periphery of the baffle, the volume of the seal is minimized, resulting in a more compact lid structure that can accommodate cups of different sizes.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0034] Please see Figures 1 to 7This application provides a cup lid 10, including a lid body 11 and a switch assembly 12. The lid body 11 has an outlet 1101 that passes through the lid body 11 along its height direction. The switch assembly 12 is slidably disposed on the lid body 11. The switch assembly 12 includes a sliding member 121 and a sealing member 122 that are connected to each other. The sliding member 121 is at least partially disposed above the lid body 11, and the sealing member 122 is at least partially disposed below the lid body 11. The sealing member 122 includes a baffle 1221 and a sealing ring 1222. The baffle 1221 is connected to the sliding member 121, and the sealing ring 1222 is sleeved on the baffle 1221. The top surface of the sealing ring 1222 is interference-fitted with the lid body 11. The sliding member 121 can drive the sealing member 122 to slide back and forth between the open position and the closed position. When the sliding member 121 is in the open position, the sealing member 122 is located beside the outlet 1101 to open the outlet 1101. When the sliding member 121 is in the closed position, the baffle 1221 blocks the outlet 1101 from below, and the sealing ring 1222 surrounds the outer peripheral area of the outlet 1101 and seals with the cover 11 to block the outlet 1101.
[0035] It is understood that in this embodiment, by making the top surface of the sealing ring 1222 and the cover 11 interference fit, that is, by physically squeezing the sealing ring 1222, a sealing structure is formed between the sealing ring 1222 and the outlet 1101 of the cover 11. This interference fit not only provides a reliable seal for the outlet 1101 at room temperature, but also maintains sufficient pressure of the sealing ring 1222 on the outlet 1101 of the cover 11 under heated conditions, even if the cover 11 or the sealing ring 1222 changes size due to thermal expansion. In other words, the interference fit compensates for the gap change between the sealing element 122 and the cover 11 caused by thermal expansion, so that the sealing surface between the sealing element 122 and the outlet 1101 always remains tight, thereby preventing liquid leakage.
[0036] Furthermore, in this embodiment, the outlet 1101 is first directly blocked from below the lid 11 by a baffle 1221, and then a sealing ring 1222 is placed around the outer periphery of the outlet 1101, forming a ring seal with the lid 11. The seal 1222 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 seal 122 by fitting the sealing ring 1222 around the outer periphery of the baffle 1221. This makes the structure of the lid 10 more compact and adaptable to cups 100 of different sizes.
[0037] In illustrative purposes, the sealing ring 1222 is made of silicone. Thus, the sealing ring 1222 not only has elasticity, allowing for an interference fit with the cover 11, but also possesses advantages such as high temperature resistance and safety. In other embodiments, the sealing ring 1222 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.
[0038] It is also understandable that when the cup lid 10 is installed on the cup body 20 of the cup 100, the spout 1101 can be opened and closed with one hand. Specifically, pushing the slider 121 from the blocked position to the open position with one hand opens the spout 1101; pushing the slider 121 from the open position to the blocked position with one hand closes the spout 1101, making the control of the spout 1101 convenient and quick. In particular, compared with the press-to-open cup lid 10, the cup lid 10 in this embodiment is more efficient in use, and therefore suitable for outdoor, sports, and other scenarios that require rapid hydration. Moreover, the sound of the push-type switch assembly 12 opening / closing the spout 1101 is quieter than that of the press-to-open cup lid 10, and will not cause noise interference when used in quiet environments such as libraries and conference rooms. In addition, the push-type switch assembly 12 is less prone to jamming or loosening after long-term use, and has a lower failure rate and longer service life compared to the spring structure of the press-type lid.
[0039] In one embodiment, a limiting structure is provided between the lid 11 and the slider 121 to restrict the slider 121 from moving from the sealed position to the open position. Thus, when the slider 121 is pushed to the sealed position, the slider 121 can be locked in the sealed position by the limiting structure. At this time, the sealing state between the seal 122 and the outlet 1101 is not affected by the shaking or inversion of the cup body 20. When carrying the cup body 20 with the lid 10 installed, there is no need to worry about the liquid leakage inside the cup body 20, making the cup 100 with the lid 10 installed in this embodiment suitable for use in mobile scenarios such as business trips and commuting.
[0040] Schematic illustration: The limiting structure can consist of two mutually abutting protrusions, which are respectively located on the slider 121 and the cover 11, for reference. Figure 4 The first limiting portion 1211 and the second limiting portion 111 are adjacent to each other. The limiting structure can also consist of a protruding structure and a limiting groove 1104 that can limit the protruding structure. One of the protruding structure and the limiting groove 1104 is provided on the sliding member 121, and the other is provided on the cover 11. See reference. Figure 5 The first limiting part 1211 and the limiting groove 1104 in the middle, in Figure 5In the illustrated embodiment, two first limiting portions 1211 are arranged at intervals along the movement direction of the slider 121, and the space between these two first limiting portions 1211 forms the aforementioned limiting groove 1104. This application does not limit the specific form of the limiting structure, as long as it can limit the slider 121 to the blocking position. It should be noted that "limiting the slider 121 from the blocking position to the opening position" means that, without applying external force, the limiting structure can prevent the slider 121 from leaving the blocking position. When the user applies a certain force to the slider 121 along the direction between the blocking position and the opening position, the slider 121 can be removed from the blocking position.
[0041] Furthermore, the limiting structure includes a first limiting part 1211 and a second limiting part 111 that can abut against each other along the movement direction of the slider 121. The first limiting part 1211 is disposed on the slider 121, and the second limiting part 111 is disposed on the cover 11. When the slider 121 is in the blocked position, the second limiting part 111 stops on one side of the first limiting part 1211 to prevent the slider 121 from leaving the blocked position. When the slider 121 is in the open position, the second limiting part 111 stops on the other side of the first limiting part 1211 to prevent the slider 121 from leaving the open position. It can be understood that regardless of whether the slider 121 is in the blocked or open position, the slider 121 is always arranged side by side with the cover 11 along the thickness direction of the cover 11. When the slider 121 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 121 will also be at a certain angle to the vertical direction. Since the second limiting part 111 stops the first limiting part 1211 to restrict the slider 121 from leaving the open position, that is, the limiting structure restricts the slider 121 to the open position. In this way, the slider 121 will not slide from the open position to the blocked position under the action of gravity, so as not to interrupt the user's drinking process of the liquid in the cup body 20.
[0042] In one embodiment, the first limiting portion 1211 protrudes downwards from the lower surface of the slider 121, and the second limiting portion 111 protrudes upwards from the upper surface of the cover 11. It is understood that the first limiting portion 1211 can slide towards the second limiting portion 111 until it abuts against the second limiting portion 111, and it can also slide away from the second limiting portion 111. Figure 3 and Figure 4The embodiment in the figure illustrates that the movement direction of the slider 121 is defined as the left-right direction. The sealing 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 121 is in the sealing position, the first limiting part 1211 is located to the left of the second limiting part 111. At this time, the second limiting part 111 can restrict the first limiting part 1211 to its left side, that is, restrict the slider 121 to the sealing position, preventing the slider 121 from moving from the sealing position to the opening position. When the slider 121 slides from the sealing position to the opening position, the first limiting part 1211 slides from the left side of the second limiting part 111 to the right side of the second limiting part 111. At this time, the second limiting part 111 can restrict the first limiting part 1211 to its right side, that is, restrict the slider 121 to the opening position, preventing the slider 121 from sliding from the opening position to the sealing position.
[0043] It should also be noted that this can be used as a reference. Figure 7 Since the cover 11 includes a top cover 112 and a side cover 113, and the side cover 113 is connected to the outer periphery of the top cover 112, the top cover 112 is located in the middle of the side cover 113 in the height direction of the cover 11. When the slider 121 is in the blocking position, the area of the side cover 113 located beside the blocking position can limit the slider 121. Specifically, the area of the side cover 113 located beside the blocking position and the second limiting part 111 are located on the left and right sides of the first limiting part 1211, respectively, thereby preventing the first limiting part 1211 from sliding left and right, thus limiting the slider 121 to the blocking position.
[0044] In one embodiment, one of the first limiting portion 1211 and the second limiting portion 111 is a limiting groove 1104, and the other is a protrusion that can abut against and cooperate with the limiting groove 1104. Schematic, the first limiting portion 1211 is a protruding structure, and the second limiting portion 111 is a limiting groove 1104 capable of accommodating the protruding structure. It is understood that the limiting groove 1104 has a cavity to accommodate the first limiting portion 1211. Since the second limiting portion 111 is provided on the cover 11, the surface of the cover 11 can be used as the bottom of the limiting groove 1104. The limiting groove 1104 also includes a groove wall, which together with the surface of the cover 11 forms the aforementioned cavity.
[0045] by Figure 5 and Figure 6The embodiment in the figure explains that the movement direction of the slider 121 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 121 is in the blocking position, the first limiting part 1211 is located to the left of the second limiting part 111, that is, the protrusion of the first limiting part 1211 is located to the left of the limiting groove 1104. At this time, the limiting groove 1104 can restrict the first limiting part 1211 to its left side, that is, restrict the slider 121 to the blocking position and prevent the slider 121 from moving from the blocking position to the opening position. As the slider 121 slides from the sealed position to the open position, the first limiting part 1211 slides from the left side of the second limiting part 111 into the cavity of the limiting groove 1104. At this time, a gap appears between the seal 122 and the outlet 1101, allowing the liquid in the drinking cup 20 to be consumed, but the outlet 1101 is not fully exposed. That is, the slider 121 is in a transitional position between the sealed and open positions. When the slider 121 slides from the transitional position to the open position, the protrusion of the first limiting part 1211 is located on the right side of the limiting groove 1104. At this time, the limiting groove 1104 can restrict the first limiting part 1211 to its right side, that is, restrict the slider 121 to the open position, preventing the slider 121 from sliding from the open position to the sealed position.
[0046] Schematic illustration: four first limiting parts 1211 and four limiting grooves 1104 are provided, with each limiting groove 1104 corresponding to one of the first limiting parts 1211. Figure 5 In the illustrated embodiment, since each limiting groove 1104 is composed of two second limiting parts 111, there are a total of 8 second limiting parts 111 in this embodiment. In other embodiments, the number of first limiting parts 1211 and second limiting parts 111 can also be other numbers, and this application does not limit this, as long as the limiting structure can limit the sliding member 121 to the blocking position or the opening position.
[0047] In other embodiments, the second limiting portion 111 is a protrusion, and the first limiting portion 1211 is a limiting groove 1104 capable of accommodating the protrusion.
[0048] In one embodiment, refer to Figure 2 and Figure 7 The upper surface of the lid 11 is recessed downward to form a groove 1102. The slider 121 is constrained by the groove 1102 and can 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 1102. In this way, the sliding direction of the slider 121 can be guided by the groove 1102, and part of the slider 121 can be hidden in the groove 1102, thereby reducing the overall height of the lid 10.
[0049] For further information, please refer to... Figure 2 and Figure 7 The second limiting part 111 is provided on the bottom surface of the slide groove 1102. In this way, the sliding stroke of the slider 121 can be precisely limited and stopped from below. The bottom-mounted limiting structure makes full use of the longitudinal space of the slide groove 1102, eliminating the need to add a complex limiting structure to the side wall of the slide groove 1102. This makes the overall structure of the cup lid 10 more compact and stable, and helps to further control and reduce the overall height of the cup lid 10, ensuring the simplicity and flatness of the appearance of the cup lid 10.
[0050] In one embodiment, reference Figure 4 and Figure 5 The sealing ring 1222 includes a ring body 12221 located on the outer periphery of the baffle 1221 and a first extension 12222 extending inward from the end of the ring body 12221 near the cover 11. The top surface of the first extension 12222 is higher than the upper surface of the baffle 1221, so that the first extension 12222 and the cover 11 are in an interference fit. That is, there is a certain gap between the upper surface of the baffle 1221 and the cover 11. Thus, when the sealing member 122 is slid along the lower surface of the cover 11 by the sliding member 121, the baffle 1221 will not rub against the cover 11. Only the first extension 12222 maintains an interference contact with the cover 11, thereby reducing the resistance of the sealing member 122 during the sliding process and making it smooth and fluid, effectively avoiding wear and jamming of the baffle 1221 due to friction.
[0051] Furthermore, by making the top surface of the sealing ring 1222 and the cover 11 interference fit, that is, by physically squeezing the sealing ring 1222, a sealing structure is formed between the sealing ring 1222 and the outlet 1101 of the cover 11. This interference fit not only provides a reliable seal for the outlet 1101 at room temperature, but also maintains sufficient pressure of the sealing ring 1222 on the outlet 1101 of the cover 11 under heated conditions, even if the cover 11 or the sealing ring 1222 changes size due to thermal expansion. In other words, the interference fit compensates for the gap change between the sealing element 122 and the cover 11 caused by thermal expansion, so that the sealing surface between the sealing element 122 and the outlet 1101 always remains tight, thereby preventing liquid leakage.
[0052] Furthermore, the end of the ring body 12221 away from the cover body 11 has a second extension 12223 extending inwardly. An annular groove 12224 is formed between the ring body 12221, the first extension 12222, and the second extension 12223. The outer periphery of the baffle 1221 is clamped in the annular groove 12224, and the second extension 12223 abuts against at least a portion of the underside of the baffle 1221. In this way, the connection between the baffle 1221 and the seal 122 is tighter, making it less likely for liquid in the cup body 20 to leak from between the baffle 1221 and the seal 122.
[0053] In one embodiment, refer to Figure 7 The direction from the open position to the sealed position is defined as the first direction X. The cover 11 also has a sliding hole 1103 extending along the first direction X. The water outlet 1101 and the sliding hole 1103 are spaced apart along the first direction X. (See reference...) Figure 3 and Figure 6 The switch assembly 12 also includes a connector 13, which passes through the sliding hole 1103 and can slide in the sliding hole 1103 along the first direction X. The two ends of the connector 13, which are arranged opposite to each other along its own length, are respectively connected to the sliding member 121 and the sealing member 122. In this way, when the sliding member 121 slides on the upper surface of the cover 11, it can drive the sealing member 122 to slide on the lower surface of the cover 11, so that the sliding member 121 can slide back and forth between the position covering the water outlet 1101 and the position next to the water outlet 1101 to block or open the water outlet 1101.
[0054] For further information, please refer to... Figure 3 and Figure 6 The switch assembly 12 also includes a stop 14, which is connected to the end of the connector 13 away from the slider 121. That is, the two ends of the connector 13, which are arranged opposite each other along its own length, are respectively connected to the slider 121 and the stop 14. The stop 14 is located below the seal 122 to prevent the seal 122 from detaching from the connector 13. It can be understood that the stop 14 and the slider 121 can physically compress the seal 122 and the cover 11, so that the sealing ring 1222 of the seal 122 is tightly fitted against the cover 11, so that the entire switch assembly 12 is stably constrained on the cover 11, avoiding the switch assembly 12 from shaking in the thickness direction of the cover 11, and especially preventing the seal 122 from loosening in the thickness direction of the cover 11. Thus, when the sliding member 121 is in the sealed position, the sealing ring 1222 can seal and cooperate with the outer peripheral area of the outlet 1101, thereby ensuring the sealing effect of the sealing member 122 on the outlet 1101.
[0055] Furthermore, the stop member 14 is connected to the connector 13 from below the seal member 122, which can fix the seal member 122 to the connector 13. This can prevent the seal member 122 from coming loose from the connector 13 due to frequent opening / closing of the water outlet 1101, shaking of the cup 100, or accidental bumps, thereby ensuring the sealing effect of the switch assembly 12 on the water outlet 1101.
[0056] Furthermore, when the slider 121 switches between the open and closed positions, the sealing ring 1222 always surrounds the outer periphery of the sliding hole 1103. This prevents liquid inside the cup body 20 from leaking through the sliding hole 1103, thereby improving the sealing effect of the switch assembly 12 on the lid 11, and consequently improving the sealing performance of the cup 100 with the lid 10 installed.
[0057] In one embodiment, refer to Figure 5 The stop member 14 has a threaded hole 1401 along the length of the connector 13, and the outer periphery of the connector 13 has an external thread that is threadedly connected to the threaded hole 1401. Thus, the switch assembly 12 has a simple structure, and the entire switch assembly 12 can be disassembled by removing the stop member 14, allowing for cleaning of the switch assembly 12 removed from the cup lid 10. This reduces scale and bacterial residue in the switch assembly 12, especially in the seal 122, improving the hygiene of the cup lid 10 and the cup 100 on which it is installed.
[0058] Schematic illustration: The seal 122 is provided with a clearance hole 12201 for the connector 13 to pass through, so that the seal 122 can be clamped between the cover 11 and the stop 14. Furthermore, since the seal 122 includes a baffle 1221 and a sealing ring 1222, the clearance hole 12201 is respectively provided on the baffle 1221 and the sealing ring 1222, so that the connector 13 can pass through the baffle 1221 and the sealing ring 1222 in sequence.
[0059] This application also provides a cup 100, which can be referenced. Figure 1 The 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 121 from the blocked position to the open position with one hand, the spout 1101 can be opened; by pushing the slider 121 from the open position to the blocked position with one hand, the spout 1101 can be closed, making it convenient to use.
[0060] 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.
[0061] 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.
