[0082] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0083] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0084] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0085] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0086] like Figure 1-Figure 6 As shown, the embodiment of the present application provides a container cover for sealing the opening of the container body 6, which includes a detachably connected inner plug 1 and a top cover 2. By removing the inner plug 1 and the top cover 2, the container cover can be easily cleaned to ensure the cleanliness and hygiene of the container cover; the inner plug 1 is used to connect the container body 6 and seal the opening of the container body 6 to prevent the leakage of the liquid in the container body 6. For example, a threaded structure 19 matching the container body 6 can be provided on the inner plug 1, and a sealing ring 7 can be provided between the inner plug 1 and the container body 6 to prevent the leakage of the liquid in the pot; the top cover 2 is connected to the top of the inner plug 1 to protect the inner plug 1 and facilitate the user to hold and remove the container cover from the container body 6. Among them, the top cover 2 is screwed and connected to the top of the inner plug 1, that is, the connection or disconnection of the top cover 2 and the inner plug 1 is achieved by rotating the top cover 2 and the inner plug 1 relative to each other, thereby facilitating the installation and removal operations of the container cover.

[0087] The container cover also includes a locking member 3, which is slidably connected to the inner plug 1. The top cover 2 is provided with a locking groove 20 that matches the locking member 3. The locking groove 20 is recessed in the inner wall of the top cover 2. The locking member 3 can move along the axial direction of the inner plug 1 to insert into the locking groove 20 or escape from the locking groove 20. The relative rotation between the top cover 2 and the inner plug 1 is limited by the locking member 3, which can ensure the reliable connection between the top cover 2 and the inner plug 1 and ensure the smooth disassembly of the top cover 2 and the inner plug 1. That is, when the locking member 3 moves toward the direction close to the top cover 2 and is inserted into the locking groove 20, the locking member 3 locks the top cover 2, so that the inner plug 1 and the top cover 2 are fixed as a whole and cannot be disengaged, thereby ensuring that the top cover 2 and the inner plug 1 will not accidentally loosen during use; when the locking member 3 moves toward the direction away from the top cover 2 and is disengaged from the locking groove 20, the locking member 3 releases the top cover 2, so that the top cover 2 and the inner plug 1 can be relatively rotated and removed, thereby realizing the disassembly and separation of the top cover 2 and the inner plug 1. In one embodiment, a water outlet channel 17 connecting the inside and outside of the container body 6 can be provided in the inner plug 1, and the liquid in the container body 6 can be poured out through the water outlet channel 17. The inner plug 1 is also provided with a water sealing assembly that can seal or open the water outlet channel 17, and the water sealing assembly includes a water sealing cover 18 installed at the bottom end of the water outlet channel 17, a top rod 180 connected to the water sealing cover 18, and a spring 182 between the top rod 180 and the inner plug 1. The inner plug 1 is also provided with a switch button 10 connected to the upper end of the push rod 180. The switch button 10 is movably mounted on the inner plug 1 and can push against the push rod 180. By pressing the switch button 10, the water sealing cover 18 is controlled to open or close the water outlet channel 17, and the switch button 10 is reset by the spring 182.

[0088] An exhaust member 100 may be provided between the switch button 10 and the top rod 180, and an exhaust hole 100a is provided on the exhaust member 100. When the switch button 10 pushes the top rod 180 to open the water outlet channel 17, the exhaust member 100 is connected to the outside world to avoid the formation of negative pressure in the container cover, which may make it difficult to pour out the liquid in the container body or cause inconvenience in operating the switch button 10. Specifically, a cavity 104 is formed between the exhaust member 100 and the switch button 10, and the exhaust hole 100a may be connected to the cavity 104, and connected to the outside world through the cavity 104.

[0089] The switch button 10 can be exposed on the top cover 2 through the mounting hole provided on the top cover 2 to facilitate user operation. An operation button 24 connected to the switch button 10 can be provided on the top cover 2. By pressing the operation button 24, the action of the switch button 10 is controlled, thereby controlling the water sealing cover 18 to open or close the water outlet channel 17, so as to avoid sliding cooperation between the switch button 10 and the top cover 2, avoid shaking of the switch button 10, and prevent wear of the switch button 10 caused by repeated installation and removal of the top cover 2.

[0090] It should be noted that, in other embodiments, the operation mode of opening or closing the water outlet channel 17 of the container cover may be different from the above-mentioned water sealing assembly and the switch button 10, for example, the container cover may be directly unscrewed to open or close the pot mouth, or the water outlet may be opened or closed by radial squeezing, or the water outlet may be opened or closed by pressing a lever. As long as the container cover includes the above-mentioned top cover 2, locking member 3 and inner plug 1, and the top cover is removed by the related structures of the locking member 3 and the inner plug 1, it is within the scope of protection of this application.

[0091] Furthermore, the outer wall of the inner plug 1 of the container cover provided in the embodiment of the present application is provided with a plurality of (including two or more) first ridges 16, the first ridges 16 extend along the circumference of the inner plug 1, and the plurality of first ridges 16 are spaced apart around the axis of the inner plug 1, and a first interval is formed between adjacent first ridges 16; the inner wall of the top cover 2 is provided with a plurality of second ridges 22, the second ridges 22 extend along the circumference of the top cover 2, and the plurality of second ridges 22 are spaced apart around the axis of the top cover 2, and a second interval is formed between adjacent second ridges 22; the second ridges 22 rotate with the top cover 2 to be inserted under the first ridges 16, thereby fixing the top cover 2 to the inner plug 1. Specifically, when installing the top cover 2, operate the top cover 2 so that the second ridge 22 and the first ridge 16 are staggered with each other, that is, the second ridge 22 is opposite to the first interval, and the first ridge 16 is opposite to the second interval, so that the top cover 2 is moved toward the inner plug 1 until the second ridge 22 passes through the first interval, and the top cover 2 is rotated so that the second ridge 22 is screwed under the first ridge 16, thereby fixing the top cover 2 to the inner plug 1.

[0092] Among them, the first ridge 16 and the second ridge 22 can be set to be matched with each other in the plane (a plane along the circumferential direction, that is, when the second ridge 22 is screwed into the bottom of the first ridge 16, the top cover 2 and the inner plug 1 do not produce an axial relative movement stroke) or a spiral surface (a surface gradually inclined along the circumferential direction, that is, when the second ridge 22 is screwed into the bottom of the first ridge 16, the top cover 2 and the inner plug 1 simultaneously produce an axial relative movement stroke). Preferably, both the first ridge 16 and the second ridge 22 are planes to avoid jamming between the top cover 2 and the inner plug 1, which makes it difficult to unscrew the top cover 2 and the inner plug 1.

[0093] Furthermore, a stopper 160 is provided below the first convex strip 16, and the stopper 160 is provided at one end of the first convex strip 16, and the locking groove 20 is provided at one end of the second convex strip 22 away from the first convex strip 16, that is, the stopper 160 and the through hole 130 are provided at both ends of the first convex strip 16, respectively, and the stopper 160 and the locking member 3 are stopped at both ends of the second convex strip 22. On the one hand, the rotation direction of the top cover 2 can be limited, and the rotation stroke of the top cover 2 can be effectively controlled, which facilitates the installation of the top cover 2; on the other hand, the locking groove 20 is located in the second interval, so as to avoid reducing the structural strength of the second convex strip 22 and ensure the reliable connection between the top cover 2 and the inner bolt 1.

[0094] Further, a first flange 13 is provided in the middle of the inner plug 1, and the first flange 13 extends along the circumference of the inner plug 1. The top cover 2 is connected to the top of the first flange 13, and the locking member 3 is connected to the bottom of the first flange 13. The locking member 3 can pass through the first flange 13 and be inserted into the locking groove 20 provided on the top cover 2. For example, a through hole 130 can be provided on the first flange 13, and the through hole 130 is directly opposite to the locking groove 20, and a part of the locking member 3 can pass through the through hole 130 and be inserted into the locking groove 20.

[0095] Furthermore, the locking member 3 can be set to an annular structure, and the locking member 3 is sleeved on the outside of the inner plug 1 and can move along the axial direction of the inner plug 1 to avoid a major impact on the original structure of the inner plug 1, so that the inner plug 1 has a higher integrity. Of course, the locking member 3 can also be set to other appropriate structures that can cooperate with the locking groove 20.

[0096] Specifically, the locking member 3 includes a body 36 sleeved on the inner plug 1 and a locking portion 30 extending from the body 36; the body 36 is located below the first flange 13, and the locking portion 30 passes through the through hole 130 provided on the first flange 13 and is inserted into the locking groove 20. The locking member 3 may be provided with a plurality of (including two or more) locking portions 30, the locking portion 30 protruding from one end of the locking member 3 facing the top cover 2, and the plurality of locking portions 30 are distributed at intervals around the axis of the inner plug 1, and the locking portion 30 moves with the body 36 to be inserted into the locking groove 20 or out of the locking groove 20, and multiple locking connections are formed between the inner plug 1 and the top cover 2 through the plurality of locking portions 30, thereby increasing the reliability and stability of the locking connection between the inner plug 1 and the top cover 2, and preventing the locking portion 30 from being damaged due to excessive force. In addition, by providing a plurality of locking portions 30 on the same body 36 , the consistency of the actions of the plurality of locking portions 30 can be ensured, and the locking member 3 can be accurately switched between the locked state and the released state.

[0097] Furthermore, a guide structure is provided between the outer wall of the inner plug 1 and the inner wall of the locking member 3, and the guide structure extends along the axial direction of the inner plug 1 to limit the movement direction of the locking member 3, so that the locking member 3 can only move along the axial direction of the inner plug 1 without rotating, thereby ensuring that the locking member 3 can be accurately inserted into the locking groove 20. For example, a guide rib 15 can be provided on the outer wall of the inner plug 1, and a guide groove 32 can be provided on the inner wall of the locking member 3, and the guide rib 15 and the guide groove 32 both extend along the axial direction of the inner plug 1, and the guide rib 15 and the guide groove 32 are slidably matched.

[0098] Furthermore, the container cover provided in the embodiment of the present application also includes a reset member 5 (such as a spring), which can be extended and retracted along the axial direction of the inner plug 1. The two ends of the reset member 5 elastically press against the locking member 3 and the inner plug 1 to force the locking member 3 to move toward the direction close to the top cover 2 until it is inserted into the locking groove 20, so that the locking member 3 can remain in the state of being inserted into the locking groove 20, preventing the locking member 3 from accidentally falling out of the locking groove 20 during use, causing the connection between the inner plug 1 and the top cover 2 to loosen.

[0099] Furthermore, the inner plug 1 is further provided with a second flange 14, and the second flange 14 is located on the side of the locking member 3 away from the top cover 2, that is, the second flange 14 is provided at the end of the inner plug 1 away from the top cover 2, and the reset member 5 is installed between the locking member 3 and the second flange 14, and the two ends of the reset member 5 elastically press against the locking member 3 and the second flange 14. The second flange 14 can be connected to the inner plug 1 by a detachable connection (such as a clamping connection or a threaded connection) to facilitate the installation of the locking member 3 and the reset member 5.

[0100] Further, in order to facilitate the operation of the locking member 30, in one embodiment, the container cover provided by the embodiment of the present application includes, in addition to all the technical features of the above-mentioned embodiments, a control member 4 connected to the locking member 3. The control member 4 is movably sleeved on the outside of the inner plug 1, and the control member 4 can rotate around the axis of the inner plug 1, and the control member 4 can move along the axial direction of the inner plug 1. For example, the control member 4 is threadedly connected to the inner plug 1, and the control member 4 is operated to rotate around the axis of the inner plug 1. The control member 4 interacts with the screw rod of the inner plug 1 to force the control member 4 and the inner plug 1 to move relative to the axial direction thereof, so that the locking member 3 is driven by the control member 4 to move along the axial direction of the inner plug 1 to escape from the locking groove 20, instead of directly operating the locking member 3 to move linearly, which can effectively avoid the locking member 3 from escaping from the locking groove 20 due to misoperation during use. In addition, when the control member 4 stops rotating, the locking member 3 also stops moving, so that the locking member 3 can be kept in a position of escaping from the locking groove 20, so as to facilitate the installation or removal of the top cover 2 and the inner plug 1.

[0101] Furthermore, a driving portion 40 may be protruding from the control member 4, and there may be multiple driving portions 40 (including two or more), and the multiple driving portions 40 are spaced apart around the axis of the inner plug 1, and the driving portion 40 protrudes from one end of the control member 4 along the axial direction of the inner plug 1 (for example, the driving portion 40 protrudes from the end of the control member 4 facing the top cover 2), and the driving portion 40 presses against the inner plug 1 and slides along the inner plug 1 to force the controllable member 4 to move along the axial direction of the inner plug 1, that is, one surface of the inner plug 1 corresponding to the driving portion 40 is a non-planar surface (for example, a spiral surface or a concave-convex surface), so that the driving portion 40 generates an axial stroke when sliding circumferentially along the inner plug 1.

[0102] Furthermore, the inner plug 1 is provided with a first groove 11 that matches with the driving part 40. The driving part 40 rotates with the control member 4, so that the driving part 40 slides into or out of the first groove 11, thereby causing the control member 4 to move along the axial direction of the inner plug 1; when the driving part 40 slides into the first groove 11, the control member 4 moves toward the direction close to the top cover 2 (see Figure 4 ), under the action of the reset member 5, the locking member 3 moves toward the direction close to the top cover 2 and remains in the state of being inserted into the locking groove 20; when the driving part 40 slides out of the first groove 11, the control member 4 moves toward the direction away from the top cover 2 (see Figure 5 ), the control member 4 drives the locking member 3 to move away from the top cover 2 and remains in a state of being out of the locking groove 20. A guide surface 400 (such as an arc surface or an inclined surface) is provided on at least one side of the driving portion 40 so that the driving portion 40 can slide out of the first groove 11 smoothly and stably.

[0103] Furthermore, a first step 34 is provided on the locking member 3, for example, a first step 34 is provided on the main body 36, and a second step 42 is provided on the control member 4. The control member 4 is sleeved on the locking member 3, and the second step 42 overlaps the top of the first step 34, so that the locking member 3 is driven to move downward by the control member 4, so that the locking member 3 is away from the top cover 2 and out of the locking groove 20.

[0104] Specifically, the control member 4 can be sleeved inside the locking member 3 or outside the locking member 3. When the control member 4 is sleeved inside the locking member 3, the first step 34 can be set on the inner wall of the body 36, and correspondingly, the second step 42 is set on the outer wall of the control member 4; when the control member 4 is sleeved outside the locking member 3, the first step 34 can be set on the outer wall of the body 36, and correspondingly, the second step 42 is set on the inner wall of the control member 4.

[0105] Specifically, the first groove 11 can be provided on the first flange 13, and the first groove 11 can penetrate the first flange 13 along the thickness direction of the first flange 13 to ensure that the driving part 40 can fully extend into the first groove 11. Of course, the first groove 11 can also be provided at other positions on the inner plug 1 and set to a depth matching the driving part 40. The first groove 11 can correspond to the through hole 130, that is, the number of the first grooves 11 is consistent with the number of the through holes 130, and the first groove 11 is provided outside the through hole 130 and communicates with the through hole 130, so as to simplify the structure of the inner plug 1 and reduce the radial dimension of the inner plug 1.

[0106] Furthermore, the inner plug 1 is provided with a second groove 12, which is spaced apart from the first groove 11 along the circumference of the inner plug 1; the driving part 40 rotates with the control member 4, so that the driving part 40 slides into or out of the second groove 12 to limit the rotation stroke of the control member 4, that is, when the driving part 40 slides into the second groove 12, the control member 4 stops rotating to avoid the control member 4 rotating at too large an angle, which makes the reset operation of the control member 4 inconvenient. The second groove 12 can also be provided on the first flange 13, and the depth of the second groove 12 should not be greater than the first groove 11, that is, the second groove 12 should be slightly recessed in the first flange 13, so that the locking member 3 can be kept in a position out of the locking groove 20.

[0107] According to the above description, the top cover 2 of the container cover provided in the embodiment of the present application is installed on the inner plug 1 by the second convex strip 22 and the first convex strip 16 being mutually buckled, and the locking member 3 is locked in the locking groove of the top cover 2 to further fix the top cover 2 on the inner plug 1. When it is necessary to remove the top cover 2, the locking member 3 must be pushed first so that the locking member 3 can move along the axial direction of the inner plug 1 and escape from the locking groove 20 before the top cover 2 can be removed, thereby avoiding the hidden danger of accidental loosening between the top cover 2 and the inner plug 1 when removing or covering the container body, such as a container.

[0108] Specifically, when removing the top cover 2, first rotate the control member 4 to make the driving portion 40 slide out of the first groove 11, and the driving portion 40 interacts with the first flange 13 to force the control member 4 to move away from the top cover 2, and drive the locking member 3 to move away from the top cover 2 through the control member 4, so that the locking member 3 escapes from the locking groove 20, and then make the top cover 2 and the inner plug 1 rotate relative to each other, so that the top cover 2 is removed from the inner plug 1.

[0109] In addition, an embodiment of the present application further provides a container, which includes the above-mentioned container cover provided in an embodiment of the present application.

[0110] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
