Description

Technical Field

[0001] This application relates to the field of consumer goods technology, specifically to a lid and a container having the lid. Background Technology

[0002] Existing containers, such as cups or kettles, are prone to splashing and scalding users during use, especially when filled with hot water, posing a significant safety hazard. Specifically, to ensure smooth water flow, existing containers for hot water typically have both the liquid outlet and air inlet simultaneously open. The air inlet outlet is usually directly facing the user, causing hot water to spray out from the outlet due to air pressure, resulting in scalding. Summary of the Invention

[0003] The main objective of this application is to provide a lid and a container having the lid to prevent scalding of the user by hot water splashing from the outlet of the lid's air inlet channel.

[0004] According to a first aspect of this application, a lid is provided for closing the mouth of a container, wherein the lid includes a lid body, a valve assembly, a vent plug assembly, and a movable pressure plate. The lid body has a liquid outlet channel and a vent channel, and its upper surface has a plug hole communicating with the vent channel. The valve assembly is disposed on the lower surface of the lid body and covers the inlet of the vent channel and the inlet of the liquid outlet channel. The vent plug assembly is movably disposed in the plug hole and covers the outlet of the vent channel. The movable pressure plate is mounted on the upper surface of the lid body and includes a pressing end, which is disposed at both ends of the lid body opposite to the outlet of the liquid outlet channel. The movable pressure plate is rotatable relative to the lid body to drive the valve assembly to simultaneously open the inlet of the vent channel and the inlet of the liquid outlet channel, and then drive the vent plug assembly to open the outlet of the vent channel, thereby allowing the vent channel to be open to the outside after a preset time since the liquid outlet channel has been opened.

[0005] According to the lid provided in this application embodiment, when in use, pressing the pressing end of the movable pressure plate opens only the liquid outlet channel while the venting channel remains closed. Therefore, the air pressure inside the container is quickly released through the liquid outlet channel. The user holds the lid near the pressing end, which is positioned opposite the outlet of the liquid outlet channel. Thus, the user is not affected by hot water splashing from the liquid outlet channel during operation, preventing scalding. After the liquid outlet channel has been open for a preset time to release the air pressure inside the container, the air pressure inside and outside the container is now balanced, making it difficult for water to flow out of the liquid outlet channel. At this time, the movable pressure plate acts on the vent plug assembly during pressing, causing the vent plug assembly to move and opening the venting channel outlet. The container can then normally vent to the outside through the venting channel, and the water inside the container will continue to flow out, ensuring smooth water flow from the container with this lid. The lid of this application solves the problem of scalding caused by splashing water from the container without affecting normal water flow.

[0006] In an embodiment, the movable pressure plate is rotatable relative to the cover body between an open position and a closed position. In the open position, the movable pressure plate is relatively far away from the valve assembly, thereby the valve assembly closes the air guide channel and the liquid outlet channel. When the movable pressure plate rotates from the open position to the closed position, the movable pressure plate sequentially presses down on the valve assembly and the vent plug assembly, so that the inlet of the air guide channel and the inlet of the liquid outlet channel are opened before the outlet of the air guide channel, thereby allowing the air guide channel to be connected to the outside after a preset time when the liquid outlet channel is opened.

[0007] Specifically, the outlet of the air guide channel is formed at the connection between the plug hole and the air guide channel, and the vent plug assembly includes a vent plug and an elastic element. The vent plug is disposed in the plug hole to cover the outlet of the air guide channel; the elastic element is disposed between the vent plug and the bottom wall of the plug hole. The movable pressure plate can drive the vent plug to move, thereby opening the air guide channel, and the elastic element applies a spring force to the vent plug to reset it, thereby sealing the air guide channel.

[0008] More specifically, a sealing ring is provided in the outlet of the air guide channel, and the sealing ring has a through vent hole. The vent plug includes a vent plug body, a connecting section extending downward from the vent plug body, and a blocking section connected to the lower end of the connecting section. The vent plug body is disposed in the plug hole. The movable pressure plate can drive the vent plug to move downward, so that a vent gap is formed between the connecting section and the vent hole to open the air guide channel. The vent plug moves upward under the action of the elastic element, so that the blocking section engages with the vent hole, thereby blocking the air guide channel.

[0009] Furthermore, both the connecting section and the sealing section are formed in a columnar shape, and the vent is a circular hole with a diameter larger than that of the connecting section and smaller than that of the sealing section.

[0010] In an embodiment, the movable pressure plate can drive the vent plug to move in the height direction of the container. The vent plug assembly also includes a vent plug fixing cover, which is installed on the upper part of the plug hole and has a guide hole arranged in the height direction. The upper end of the vent plug body passes through the guide hole and can move along the inner wall of the guide hole.

[0011] In one embodiment, the upper end of the vent plug body can protrude from the guide hole or be flush with the upper surface of the guide hole to abut against the movable pressure plate. A stop protrusion is formed on the upper part of the vent plug body. When the vent plug moves upward to the highest point, the stop protrusion abuts against the lower surface of the vent plug fixing cover, so that the sealing section is engaged with the vent hole. When the vent plug moves downward to the lowest point, the connecting section is placed in the vent hole, and the upper end of the vent plug body remains in the guide hole.

[0012] In one embodiment, the liquid outlet is formed on one side of the cover body. The first end of the movable pressure plate is located near the liquid outlet, and the second end of the movable pressure plate extends toward the opposite side of the liquid outlet and serves as the pressing end. The lower surface of the movable pressure plate is provided with a first abutment and a second abutment. In the closed position, the first abutment abuts against the valve assembly, and the second abutment abuts against the vent plug assembly. When the movable pressure plate rotates from the open position to the closed position, the movement path of the first abutment contacting the valve assembly is shorter than the movement path of the second abutment contacting the vent plug assembly.

[0013] In this embodiment, the first abutting part and the second abutting part are arranged sequentially along the extending direction of the movable pressure plate. The first abutting part is farther away from the pressing end relative to the second abutting part. The movable pressure plate and the cover body are rotatably connected by a rotating shaft. The rotating shaft is located between the first end of the movable pressure plate and the first abutting part. The path of the first abutting part and the second abutting part rotating around the rotating shaft is the corresponding moving path.

[0014] In one embodiment, the upper surface of the cover body is provided with a relatively protruding mounting seat, and the two opposite side walls of the mounting seat are provided with shaft holes. The two side walls of the movable pressure plate are provided with the rotating shaft, and the rotating shaft is disposed in the shaft hole, so that the movable pressure plate can rotate relative to the cover body.

[0015] In one embodiment, two protrusions are formed on the lower surface of the cover body. The inlet of the gas guide channel and the inlet of the liquid outlet channel are respectively formed on the bottom wall of the corresponding protrusions. The cover body is provided with a through axial hole located between the two protrusions. The valve assembly includes a valve plug and a valve stem. The valve plug seals the inlet of the gas guide channel and the inlet of the liquid outlet channel. The lower end of the valve stem is fixedly connected to the valve plug. The upper end of the valve stem passes through the axial hole and abuts against the movable pressure plate. By pressing the movable pressure plate, the valve plug can be squeezed to move downward to open the inlet of the gas guide channel and the inlet of the liquid outlet channel.

[0016] In one embodiment, the upper surface of the cover body is recessed downward to form a reset assembly receiving groove, the reset assembly receiving groove is arranged around the axial through hole, the valve assembly further includes a reset assembly, the reset assembly includes a reset spring and a limiting part installed on the upper end of the valve stem, the upper end of the reset spring abuts against the lower surface of the limiting part, the lower end of the reset spring abuts against the bottom wall of the reset assembly receiving groove, and the reset spring applies an upward elastic force to the valve plug.

[0017] In one embodiment, a first sealing plug and a second sealing plug are installed on the upper surface of the valve plug. The first sealing plug is used to block the inlet of the liquid outlet channel, and the second sealing plug is used to block the inlet of the gas guide channel. The gas guide channel and the liquid outlet channel are respectively through grooves extending outward from the lower surface of the cover body to the outer side wall of the cover body. The two through grooves are connected to each other inside the cover body near the inlet end and extend in opposite directions.

[0018] In one embodiment, the cover further includes a top cover connected to the top of the cover body, at least partially covering the movable pressure plate, such that the movable pressure plate is rotatable between the top cover and the cover body, the top cover having a notch on one side, through which the pressing end of the movable pressure plate can be exposed or can extend out of the cover.

[0019] In these embodiments, a top cover is provided on the outside of the movable pressure plate to conceal imperfections and improve the product's aesthetics. The rotation range of the movable pressure plate is set between the top cover and the cover body, ensuring that the imperfections are concealed without affecting the normal use of the movable pressure plate. A notch is provided on one side of the top cover, allowing the pressing end of the movable pressure plate to be exposed through the notch or to protrude from the cover. This eliminates the need to remove the top cover when operating the movable pressure plate, thus facilitating user operation.

[0020] According to a second aspect of this application, a container is also provided, wherein the container includes a container body and a lid provided according to the various embodiments described above.

[0021] In one embodiment, the container body includes a pot body and a fixing seat installed at the edge of the cup mouth of the pot body. The lid body is supported on the fixing seat and is detachably connected to the fixing seat, and seals the cup mouth of the pot body.

[0022] In one embodiment, the fixed base is provided with a liquid outlet that extends horizontally through the base, and the liquid outlet channel is formed on the side wall of the cover body and communicates with the liquid outlet to form the flow channel of the container.

[0023] In an embodiment, the container further includes a handle fixing ring and a base. The handle fixing ring is installed on the side wall of the container body, and the base is installed on the bottom of the container body. The outer side walls of the handle fixing ring and the base are provided with planar structures. The two planar structures and the liquid outlet are located on the same side of the container, and the two planar structures are configured as a supporting plane when the container is placed flat.

[0024] In one embodiment, the container further includes a handle assembly installed between the handle retaining ring and the base, and positioned on the side opposite to the liquid outlet. Attached Figure Description

[0050] It should be noted that the directional terms such as "upper," "lower," "top," and "bottom" used in this application are all based on the orientation of the product when it is placed upright in normal use. They should not be construed as specific limitations on the embodiments of this application. Furthermore, in the context, it should be explained that when referring to a connection between one element and another, it can be either a direct or indirect connection, unless explicitly stated that one element is directly connected to another.

[0051] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. 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.

[0052] 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.

[0053] The following will refer to Figures 1 to 6 To specifically describe the lid provided according to the embodiments of this application, refer to Figures 1 to 11 This application provides a detailed description of the container provided according to the embodiments of this application.

[0054] According to a first aspect of this application, a lid is provided for engaging with the rim of a container to seal the rim. Specifically, the container can be a cup or a kettle. Figures 1 to 4As shown, the lid includes a lid body 10, a valve assembly 40, a vent plug assembly 50, and a movable pressure plate 60. The cover body 10 is provided with a liquid outlet channel 20 and a gas outlet channel 30. The upper surface of the cover body 10 is provided with a plug hole 11 communicating with the gas outlet channel 30. A valve assembly 40 is provided on the lower surface of the cover body 10 to cover the gas outlet channel inlet 31 and the liquid outlet channel inlet 21. A vent plug assembly 50 is movably provided in the plug hole 11 to cover the gas outlet channel outlet 32. A movable pressure plate 60 is installed on the upper surface of the cover body 10. The movable pressure plate 60 includes a pressing end 64, which is disposed at both ends of the cover body 10 opposite to the liquid outlet channel outlet 22. The movable pressure plate 60 can rotate relative to the cover body 10 to first drive the valve assembly 40 to open the gas outlet channel inlet 31 and the liquid outlet channel inlet 21 simultaneously. After the gas outlet channel inlet 31 and the liquid outlet channel inlet 21 are opened, the movable pressure plate 60 then drives the vent plug assembly 50 to open the gas outlet channel outlet 32, so that the gas outlet channel 30 is connected to the outside after the liquid outlet channel 20 has been opened for a preset time.

[0055] According to the lid provided in the embodiment of this application, when in use, pressing the pressing end 64 of the movable pressure plate 60 opens only the liquid outlet channel 20 while the air guide channel 30 remains closed. Therefore, the air pressure inside the container will quickly be discharged from the liquid outlet channel outlet 22 through the liquid outlet channel 20. During operation, the user's hand will be held near the pressing end 64, and the pressing end 64 is positioned opposite to the liquid outlet channel outlet 22. Therefore, during operation, the user will not be affected by the hot water splashed from the liquid outlet channel 20, thereby avoiding scalding. After the liquid outlet channel 20 is opened for a preset time to release the air pressure inside the container, the air pressure inside and outside the container is basically in equilibrium. Water will not easily flow out of the liquid outlet channel 20 at this time. During this downward pressing process, the movable pressure plate 60 continues to act on the vent plug assembly 50, causing the vent plug assembly 50 to move and opening the venting channel outlet 32. The container can then normally vent to the outside through the venting channel 30, and the water inside the container will continue to flow out, thus ensuring smooth water flow from the container with the lid. The lid of this application solves the problem of scalding users due to splashing from the container without affecting normal water flow.

[0056] According to this application, the movable pressure plate 60 moves downward and acts sequentially on the valve assembly 40 and the vent plug assembly 50. Since it acts on the valve assembly 40 first, it can smoothly open the liquid outlet channel inlet 21, connecting the liquid outlet channel inlet 21 and the liquid outlet channel outlet 22. Thus, after the liquid outlet channel inlet 21 is opened, the liquid outlet channel 20 is in a conductive state. In this case, the air pressure inside the container will be effectively and quickly released from the liquid outlet channel 20, ensuring that the air pressure inside and outside the container is basically balanced before the movable pressure plate 60 acts on the vent plug assembly 50. Therefore, after the venting channel 30 is opened, splashing will not occur at the venting channel outlet 32 ​​due to air pressure difference, avoiding burns to the user. When the movable pressure plate 60 acts on the vent plug assembly 50, the air guide channel 30 can be opened. At this time, the opening of the air guide channel 30 is only to allow air to enter from the air guide channel 30 during the continued pouring of water, so that the air pressure inside and outside the container can be balanced, and to avoid the water flow being obstructed due to the low air pressure inside the container.

[0057] In this embodiment, the movable pressure plate 60 is rotatable relative to the cover body 10 between an open position and a closed position. For example... Figures 1 to 4 As shown, in the open position, the movable pressure plate 60 is relatively far away from the valve assembly 40, thereby closing the air guide channel 30 and the liquid outlet channel 20. When the movable pressure plate 60 rotates from the open position to the closed position, it sequentially presses down on the valve assembly 40 and the vent plug assembly 50, causing the air guide channel inlet 31 and the liquid outlet channel inlet 21 to open before the air guide channel outlet 32. In other words, the movable pressure plate 60 can first drive the valve assembly 40 to open the air guide channel inlet 31 and the liquid outlet channel inlet 21, and then drive the vent plug assembly 50 to open the air guide channel outlet 32. This arrangement ensures that the air guide channel 30 is open to the outside after a preset time when the liquid outlet channel 20 is open. The preset time is the interval between the movable pressure plate 60 acting on the valve assembly 40 and the vent plug assembly 50 sequentially. The interval can be set according to actual conditions, such as, but not limited to, the gas pressure generated by the hot water in the container.

[0058] In this embodiment, the vent outlet 32 ​​is formed at the connection between the plug hole 11 and the vent channel 30. The vent plug assembly 50 includes a vent plug 51 and an elastic member 52. The vent plug 51 is disposed in the plug hole 11 to cover the vent channel outlet 32. The elastic member 52 is disposed between the vent plug 51 and the bottom wall of the plug hole 11. A movable pressure plate 60 can drive the vent plug 51 to move, thereby opening the vent channel 30, allowing the container to normally vent to the outside through the vent channel 30. The elastic member 52 applies a spring force to the vent plug 51 to reset it, so that when the pressure is released, the vent plug 51 automatically seals at the vent channel outlet 32 ​​under the spring force of the elastic member 52, thereby sealing the vent channel 30 of the lid. In an exemplary embodiment, the vent plug is made of rubber or silicone and can be press-fitted with the vent channel outlet 32 ​​to ensure the sealing effect of the vent channel 30.

[0059] To further enhance the sealing effect, a sealing ring 33 is provided in the outlet 32 ​​of the air guide channel. The sealing ring 33 has a through vent hole 331, which is arranged axially. The movable pressure plate 60 can drive the vent plug 51 to move downward, so that there is an air guide gap between the vent plug 51 and the vent hole 331, thereby opening the air guide channel 30. The vent plug 51 can move upward under the action of the elastic member 52 and press against the vent hole 331, thereby sealing the outlet 32 ​​of the air guide channel. In an exemplary embodiment, the sealing ring 33 includes a sealing ring body and an upper flange and a lower flange formed at the upper and lower ends of the sealing ring body. The sealing ring body is inserted into the outlet 32 ​​of the air guide channel, the upper flange abuts against the upper outer periphery of the outlet 32 ​​of the air guide channel, and the lower flange abuts against the lower outer periphery of the outlet 32 ​​of the air guide channel. Specifically, the sealing ring body is formed into an annular structure with an internal vent hole 331.

[0060] In these embodiments, the air plug 51 cooperates with the sealing ring 33 installed in the air duct outlet 32 ​​to ensure a tight seal.

[0061] According to this application, the movable pressure plate 60 can drive the vent plug 51 to move in the height direction of the container (e.g., a kettle), thereby enabling the opening or blocking of the vent passage 30. Specifically, pressing the movable pressure plate 60 can drive the vent plug 51 to move downward, thereby opening the vent passage 30, and the elastic member 52 is used to apply a spring force to the vent plug 51 to reset it, thereby blocking the vent passage 30 of the lid. Figures 1 to 4As shown, the vent plug 51 includes a vent plug body 511, a connecting section 512 extending downward from the vent plug body 511, and a sealing section 513 connected to the lower end of the connecting section 512. The vent plug body 511 is disposed in the plug hole 11. The movable pressure plate 60 can drive the vent plug 51 to move downward, so that a ventilation gap is formed between the connecting section 512 and the vent hole 331 to serve as the outlet 32 ​​of the air guide channel, thereby opening the air guide channel 30. The vent plug 51 moves upward under the action of the elastic member 52, so that the sealing section 513 is interference-fitted with the vent hole 331, thereby sealing the outlet 32 ​​of the air guide channel, so that the air guide channel 30 is not connected to the outside.

[0062] In an exemplary embodiment, both the connecting section 512 and the sealing section 513 are cylindrical, and the vent 331 is a circular hole. The diameter of the vent 331 is larger than the diameter of the connecting section 512 and smaller than the diameter of the sealing section 513. Specifically, the cylindrical shape has a predetermined height, which can be specifically set according to the distance the vent plug 51 moves up and down, and will not be described in detail here.

[0063] In these embodiments, by placing the connecting section 512 in the vent hole 331, a venting gap can be formed, enabling the air guide channel 30 to communicate with the outside. By placing the blocking section 513 in the vent hole 331 and interfering with the vent hole 331, the air guide channel 30 is not connected to the outside, resulting in a simple structure.

[0064] In one embodiment, the vent plug assembly 50 further includes a vent plug retaining cap 53, which is mounted on the upper part of the plug hole 11. In an exemplary embodiment, the vent plug retaining cap 53 is fixed to the upper part of the plug hole 11 by a threaded connection or snap-fit. The vent plug retaining cap 53 has a guide hole 531 extending along the height direction of the container, and the vent plug body 511 passes through the guide hole 531 and is movable along the inner wall of the guide hole 531, thereby enabling the vent plug 51 to move along the height direction of the container.

[0065] In these embodiments, the vent plug 51 is installed in the plug hole 11, and a vent plug fixing cover 53 is fixedly provided on the upper part of the plug hole 11, thereby preventing the vent plug 51 from detaching from the plug hole 11.

[0066] In this embodiment, the upper end of the vent plug body 511 can at least pass through the lower port of the guide hole 531 and abut against the movable pressure plate 60. Specifically, the upper end of the vent plug body 511 can protrude from the guide hole 531 or be flush with the upper end surface of the guide hole 531, which facilitates abutment against the movable pressure plate 60. Thus, the movable pressure plate 60 directly acts on the vent plug assembly 50, ensuring the reliability of the movement of the vent plug 51. A stop protrusion 5111 is formed on the upper part of the vent plug body 511. When the vent plug 51 moves upward to the highest point, the stop protrusion 5111 abuts against the lower surface of the vent plug fixing cover 53, so that the sealing section 513 is stably placed in the vent hole 331 to ensure the stability of sealing the outlet 32 ​​of the air passage. When the vent plug 51 moves downward to the lowest point, the connecting section 512 is placed in the vent hole 331, which can ensure that the container in this state can normally ventilate to the outside. Furthermore, the upper end of the vent plug body 511 remains in the guide hole 531. With the vent plug 51 always kept in the guide hole 531, the vent plug 51 can always move back and forth along the height direction of the container, thereby ensuring the accuracy of the connecting section 512 and the sealing section 513 acting on the vent hole 331.

[0067] like Figures 3 to 6 As shown, the liquid outlet 22 is formed on one side of the cover body 10. The first end of the movable pressure plate 60 is disposed near the liquid outlet 22, and the second end of the movable pressure plate 60 extends toward the opposite side of the liquid outlet 22 and serves as a pressing end 64. The lower surface of the movable pressure plate 60 is provided with a first abutment portion 61 and a second abutment portion 62. When the movable pressure plate 60 is in the closed position, the first abutment portion 61 abuts against the valve assembly 40, and the second abutment portion 62 abuts against the vent plug assembly 50. When the movable pressure plate 60 rotates from the open position to the closed position, the movement path of the first abutment portion 61 to contact the valve assembly 40 is shorter than the movement path of the second abutment portion 62 to contact the vent plug assembly 50. In an exemplary embodiment, both the first abutment portion 61 and the second abutment portion 62 are abutment protrusions protruding relative to the lower surface of the movable pressure plate 60.

[0068] In this embodiment, the first abutting part 61 and the second abutting part 62 are arranged sequentially along the extending direction of the movable pressure plate 60. The first abutting part 61 is away from the pressing end 64 of the movable pressure plate 60 relative to the second abutting part 62. The movable pressure plate 60 and the cover body 10 are rotatably connected by a rotating shaft 63. The rotating shaft 63 is located between the first end of the movable pressure plate 60 and the first abutting part 61. The path of the first abutting part 61 and the second abutting part 62 rotating around the rotating shaft 63 is the corresponding moving path.

[0069] In this embodiment, a protruding plate is provided on the lower surface of the movable pressure plate between the second abutting part 62 and the pressing end 64. The protruding plate can extend downward from the lower surface of the movable pressure plate and cover the outside of the vent plug fixing cover 53, thereby shielding the components located inside and improving the aesthetics of the product.

[0070] like Figure 5 and Figure 6 As shown, the upper surface of the cover body 10 is provided with a relatively protruding mounting seat 12. The two opposite side walls of the mounting seat 12 are provided with shaft holes 121. The two side walls of the movable pressure plate 60 are provided with rotating shafts 63, which are disposed in the shaft holes 121, so that the movable pressure plate 60 can rotate relative to the cover body 10.

[0071] In one embodiment, two protrusions 14 are formed on the lower surface of the cover body 10. The air inlet 31 and the liquid outlet inlet 21 are respectively formed on the bottom wall of the corresponding protrusions 14. The cover body 10 is provided with a through axial hole 13, which is located between the two protrusions 14. The valve assembly 40 includes a valve plug 41 and a valve stem 42. The valve plug 41 is used to seal the air inlet 31 and the liquid outlet inlet 21. The lower end of the valve stem 42 is fixedly connected to the valve plug 41, and the upper end of the valve stem 42 passes through the axial hole 13 and can abut against the movable pressure plate 60. By pressing the pressing end 64 of the movable pressure plate 60, the valve plug 41 can be squeezed downward to open the air inlet 31 and the liquid outlet inlet 21. In an exemplary embodiment, the valve plug 41 and the valve stem 42 can be integrally formed into an inverted T-shaped structure.

[0072] In one embodiment, the upper surface of the cover body 10 is recessed downward to form a reset assembly receiving groove 15. The reset assembly receiving groove 15 is arranged around the outer periphery of the axial through hole 13. The valve assembly 40 also includes a reset assembly 43, which includes a reset spring 431 and a limiting part 432 mounted on the upper end of the valve stem 42. The upper end of the reset spring 431 abuts against the lower surface of the limiting part 432, and the lower end of the reset spring 431 abuts against the bottom wall of the reset assembly receiving groove 15. The reset spring 431 applies an upward elastic force to the valve plug 41. In an exemplary embodiment, the limiting part 432 is a limiting ring sleeved on the upper end of the valve stem 42.

[0073] In this embodiment, the limiting part 432 and the return spring 431 are used as the return assembly 43 of the valve assembly 40. During installation, the upper end of the valve stem 42 passes through the axial through hole 13, and the return spring 431 is sleeved on the upper end of the valve stem 42. Then, the limiting part 432 is fixed to the upper end of the valve stem 42. Under the pressure of the movable pressure plate 60, the valve stem 42 moves downward and drives the valve plug 41 to move downward. The return spring 431 can be elastically pressed between the lower surface of the limiting part and the bottom wall of the return assembly mounting cylinder. When the pressure of the movable pressure plate 60 is removed, the valve stem 42 can drive the valve plug 41 to move upward under the elastic force of the return spring 431 so that the valve plug 41 blocks the gas guide channel inlet 31 and the liquid outlet channel inlet 21.

[0074] In this embodiment, a valve stem sealing ring 421 is provided in the axial through hole 13. The valve stem 42 fits against the inner wall of the valve stem sealing ring 421 and can move up and down along the height direction. This arrangement can ensure the sealing performance of the valve stem 42 during the up and down movement and prevent water or air leakage from the gap.

[0075] In this embodiment, a first sealing plug 91 and a second sealing plug 92 are installed on the upper surface of the valve plug 41. The first sealing plug 91 is located at the lower end of the liquid outlet channel inlet 21 and is used to block the liquid outlet channel inlet 21. The second sealing plug 92 is located at the lower end of the gas guide channel inlet 31 and is used to block the gas guide channel inlet 31. The gas guide channel 30 and the liquid outlet channel 20 are respectively through grooves formed by extending outward from the lower surface of the cover body 10 to the outer side wall of the cover body 10. The two through grooves are connected to each other inside the cover body 10 near the inlet end and extend in opposite directions. When the container is used horizontally, the gas in the container will enter the liquid outlet channel through the gas guide channel, so that splashing can be prevented when the container is used horizontally.

[0076] In the prior art, some lid bodies have an air intake channel outlet on their side walls that communicates with the air intake channel. According to this application, existing lids can be designed to prevent splashing, or a new mold with a splash-proof lid can be manufactured. Since mold production costs are high, to utilize existing molds, splash-proof modifications can be made to existing lids. Specifically, a plug hole 11 can be formed on the upper surface of the lid body 10 and communicate with the middle section of the air guide channel 30. The connection between the plug hole 11 and the air guide channel 30 can then serve as the outlet of the air guide channel 30. A sealing plug 341 is provided in the side exhaust hole 34 (equivalent to the air intake channel outlet in the prior art). The sealing plug 341 can block the side exhaust hole 34, thereby ensuring that the originally designed side exhaust hole 34 no longer functions as a conduit, thus achieving the splash-proof modification of the existing lid. Continuing with the example above, the air duct 30 is a through groove that extends outward from the lower surface of the cover body 10 to the outer side wall of the cover body 10. The outer opening of the through groove serves as the aforementioned side exhaust hole 34. When performing anti-splash modification, this side exhaust hole 34 needs to be sealed to ensure that there is no air or water leakage from this outlet during use.

[0077] In one embodiment, the lid further includes a top cover 70, which is attached to the top of the lid body 10 and at least partially covers the movable pressure plate 60, allowing the movable pressure plate 60 to rotate between the top cover 70 and the lid body 10. One side of the top cover 70 has a notch 71 through which the pressing end 64 of the movable pressure plate 60 can be exposed or protrude from the lid.

[0078] In these embodiments, a top cover 70 is provided on the outside of the movable pressure plate 60 to conceal imperfections and improve the product's aesthetics. The rotation range of the movable pressure plate 60 is set between the top cover 70 and the cover body 10, so that imperfections are concealed without affecting the normal use of the movable pressure plate 60. A notch 71 is provided on one side of the top cover 70, through which the pressing end 64 of the movable pressure plate 60 can be exposed or can protrude from the cover. This eliminates the need to remove the top cover 70 when operating the movable pressure plate 60, thus facilitating user operation.

[0079] In one embodiment, the lid also includes an outer cover 80 for connecting to the mouth of the cup and covering the outside of the top cover 70.

[0080] According to a second aspect of this application, a container is provided, wherein the container includes a container body and a 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.

[0081] like Figures 7 to 11As shown, the container body includes a pot body 100 and a fixing seat 110 installed on the edge of the cup mouth of the pot body 100. The lid body 10 is supported on the fixing seat 110, detachably connected to the fixing seat 110, and sealed to the cup mouth of the pot body 100.

[0082] In an exemplary embodiment, the fixing base 110 includes an outer ring sleeve, an inner ring sleeve, and a connecting rib connecting the outer ring sleeve and the inner ring sleeve. The outer ring sleeve is disposed on the outer side wall of the kettle body, and the inner ring sleeve is disposed on the inner side wall of the kettle body. The connecting rib supports the upper end of the cup mouth. A fixing base sealing ring 113 is provided at the lower end of the connecting rib between the outer ring sleeve and the inner ring sleeve to seal the gap between the kettle body 100 and the fixing base 110. One of the side wall of the inner ring sleeve and the outer side wall of the lid body is provided with a retaining rib 112, and the other is provided with a retaining groove. The retaining rib engages with the retaining groove, thereby detachably connecting the lid body 10 and the fixing base 110. A water-blocking sealing ring 93 is provided at the bottom of the lid body 10 to seal the cup mouth of the kettle body 100.

[0083] According to this application, the liquid outlet 22 can be directly used as the drinking spout of the container, or it can be connected to the drinking spout of the container. In an embodiment, the fixing base 110 is provided with a liquid outlet 111 that extends horizontally through the container. The liquid outlet 22 is formed on the side wall of the cover body 10 and communicates with the liquid outlet 111 to form a flow channel for liquid discharge from the container, wherein the liquid outlet 111 serves as the drinking spout of the container.

[0084] In this embodiment, the container also includes a handle fixing ring 200 and a base 300. The handle fixing ring 200 is installed on the side wall of the container body 100, and the base 300 is installed on the bottom of the container body 100. The outer side walls of the handle fixing ring 200 and the base 300 are provided with a planar structure 210 and a planar structure 310, respectively. The two planar structures and the liquid outlet 111 are located on the same side of the container. The two planar structures are configured as a support plane for the container when it is placed flat. When the container is used flat, it is supported by the support plane to prevent the container from rolling.

[0085] In this embodiment, the container also includes a handle assembly 400, which is installed between the handle fixing ring 200 and the base 300 and is located on the side opposite to the liquid outlet 111, so that the container can be easily lifted by the handle assembly 400, thereby making it convenient for the user to carry the container.

[0086] like Figure 10As shown, the container of this application can be used in multiple scenarios. For example, it can be placed flat on the support platform 500 to pour water, or it can be held by hand and poured using a common tilting method. When used flat on the support platform 500, it is more advantageous for women with less strength, as the container can be lifted by the handle assembly 400 to place it flat on the support platform 500 for pouring water, which is very effortless.

[0087] As an example, when used horizontally, when the movable pressure plate is pressed to the first position to open both the air inlet 31 and the liquid outlet inlet 21, the liquid outlet 20 is opened. During the water flow, the gas is also released to the outside along with the vortex generated by the water flow. As a result, the larger gas pressure inside the container is released at this time, and the gas pressure inside and outside the container gradually tends to be balanced during the pouring process. Therefore, when the movable pressure plate is pressed to the second position to open the air outlet 32 ​​and open the air outlet 30, splashing will not occur at the air outlet 32 ​​due to the pressure difference, thus avoiding burns.

[0088] In this embodiment, the handle fixing ring 200 and the base 300 are respectively provided with mounting grooves. During installation, the handle fixing ring 200 can be inserted first, then the upper end of the handle assembly 400 can be inserted into the corresponding mounting groove of the handle fixing ring 200, then the lower end of the handle assembly 400 can be inserted into the mounting groove of the base 300, and finally the base 300 can be assembled on the bottom of the kettle body.

[0089] According to the container provided in the embodiment of this application, when the movable pressure plate 60 is pressed, the movable pressure plate 60 can first act on the valve assembly 40 to open the liquid outlet channel 20, so that the air pressure in the pot body 100 will be released quickly through the liquid outlet channel 20, and then act on the vent plug assembly 50 to allow the air guide channel 30 to normally guide air to the outside, thus meeting the requirement of smooth water discharge.

[0090] 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.
