DETAILED DESCRIPTION

[0065] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0066] In the description of the present application, it should be understood that the terms "center", "transverse", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the protection scope of the present application.

[0067] As Figures 1 to 3As shown, in some embodiments of the container cover provided by the present application, the container cover comprises a cover body 10 and a suction nozzle 20, the cover body 10 comprises a first accommodating cavity 11 and a connecting part 17 for connecting with the container body, the first accommodating cavity 11 is in fluid communication with the container body, the suction nozzle 20 is arranged in the first accommodating cavity 11, the suction nozzle 20 comprises a second accommodating cavity 21 and an outlet 22 for connecting the first accommodating cavity 11 and the second accommodating cavity 21, the suction nozzle 20 is movably arranged relative to the cover body 10, the suction nozzle 20 has a retracted state and a pulled-out state, in the retracted state, the outlet 22 is in a closed state, the first accommodating cavity 11 and the second accommodating cavity 21 are not connected; in the pulled-out state, the outlet 22 is in an open state, the first accommodating cavity 11 and the second accommodating cavity 21 are connected.

[0068] In the above-mentioned embodiments, the suction nozzle 20 is movably arranged relative to the cover body 10, and the suction nozzle 20 is switched between the retracted state and the pulled-out state by the movement relative to the cover body 10, which can increase the fun of use, improve the use experience of consumers, and enhance the recognition of the container cover by consumers.

[0069] When the suction nozzle 20 is in the retracted state, the outlet 22 is in a closed state, the first accommodating cavity 11 and the second accommodating cavity 21 are not connected, that is, the liquid in the container body cannot enter the suction nozzle 20, and the suction nozzle 20 is in a non-water-out state. When the suction nozzle 20 is in the pulled-out state, the outlet 22 is in an open state, the first accommodating cavity 11 and the second accommodating cavity 21 are connected, that is, the liquid in the container body can enter the suction nozzle 20, and the suction nozzle 20 is in a water-out state.

[0070] Among them, the suction nozzle 20 in the pulled-out state does not mean that the suction nozzle 20 is completely pulled out, and the specific conditions of the suction nozzle 20 in the pulled-out state will be described in more detail below.

[0071] In the above-mentioned embodiments, the connecting part 17 is used to connect the cover body 10 and the container body, and the connecting part 17 can be arranged on the inner wall of the first accommodating cavity 11 or outside the first accommodating cavity 11. For example, the connecting part 17 can comprise an inner thread arranged on the inner wall of the first accommodating cavity 11, and the end of the container body is provided with an outer thread, and the end of the container body is screwed into the inside of the first accommodating cavity 11 through the cooperation of the inner thread and the outer thread, thereby achieving the effect of sealing the container body.

[0072] In some embodiments, the connecting part 17 can further comprise a plurality of first connecting bridge points arranged on the end of the cover body 10, the plurality of first connecting bridge points are arranged in a circumferential direction, a first sealing ring is arranged on the container body, and the cover body 10 is connected with the first sealing ring through the plurality of first connecting bridge points. When the consumer rotates the cover body 10, the first connecting bridge points will be broken, thereby breaking the connection between the first sealing ring and the cover body 10.

[0073] By arranging the first sealing ring, the sealing performance of the joint between the cover 10 and the container body can be enhanced, and the liquid in the container body can be prevented from being contaminated.

[0074] In some embodiments, the nozzle 20 is movable relative to the cover 10 along the central axis of the cover 10.

[0075] As shown in the structural schematic view, the side view and the cross-sectional view of the cover 10 respectively. Figures 4 to 6 Figure 6 The central axis of the cover 10 is shown in the middle. The central axis is a line connecting the center of the top surface and the center of the bottom surface of the cover 10.

[0076] When the consumer picks up the container to drink water, the container body and the container cover are tilted, and the liquid in the container body flows out along the central axis of the cover 10.

[0077] When the container body and the container cover are both cylindrical structures, the central axis of the cover 10 is parallel to and collinear with the central axis of the container body.

[0078] The nozzle 20 moves along the central axis of the cover 10, which is basically consistent with the direction of the liquid flowing out of the container body, which is beneficial to improve the user experience of the consumer.

[0079] In some embodiments, the nozzle 20 moves linearly along the central axis of the cover 10.

[0080] In some embodiments, the container cover further comprises an inner plug 30, which is arranged in the first accommodating cavity 11. The inner plug 30 comprises a third accommodating cavity 31 in fluid communication with the container body, and the nozzle 20 is arranged in the third accommodating cavity 31 and is movably arranged relative to the inner plug 30.

[0081] By arranging the inner plug 30 between the cover 10 and the nozzle 20, the nozzle 20 can be conveniently supported and fixed by the inner plug 30, so as to prevent the nozzle 20 from shaking in the first accommodating cavity 11 of the cover 10, and affect the stability of the nozzle 20 and the smoothness of the water outlet.

[0082] As shown in the structural schematic view, the side view and the cross-sectional view of the cover 10 respectively. Figures 7 to 13 In some embodiments, the inner plug 30 comprises a sealing portion 32 arranged on the inner wall of the third accommodating cavity 31 and used for blocking the outlet 22. In the retracted state, the nozzle 20 moves relative to the inner plug 30 to a position where the sealing portion 32 blocks the outlet 22, so as to close the outlet 22. In the pulled-out state, the nozzle 20 moves relative to the inner plug 30 to a position where the outlet 22 is away from the sealing portion 32, so that the sealing portion 32 has a preset distance from the outlet 22, thereby opening the outlet 22.

[0083] By arranging the sealing portion 32, the outlet 22 can be blocked to prevent water leakage. ​

[0084] In some embodiments, the sealing portion 32 is further configured to limit the movement of the suction nozzle 20 relative to the inner plug 30. The sealing portion 32 can also position and fix the suction nozzle 20 to prevent the suction nozzle 20 from shaking within the third accommodating cavity 31 of the inner plug 30.

[0085] In some embodiments, the suction nozzle 20 includes a plurality of first blocking portions 23, the plurality of first blocking portions 23 are arranged at intervals in the circumferential direction, and an outlet 22 is formed between two first blocking portions 23. The sealing portion 32 includes a first sealing portion 321, in the retracted state, the first blocking portion 23 is in contact with the first sealing portion 321 to close the outlet 22 by the first sealing portion 321; in the pulled-out state, there is a gap between the first blocking portion 23 and the first sealing portion 321 to open the outlet 22.

[0086] Reference Figure 17 and Figure 18 As shown, the first sealing portion 321 is continuous in the circumferential direction, and when the first blocking portion 23 is in contact with the first sealing portion 321, the first blocking portion 23 not only blocks the movement of the suction nozzle 20 through the first sealing portion 321, but also closes the outlet 22 to achieve the purpose of blocking the water flow.

[0087] When there is a gap between the first blocking portion 23 and the first sealing portion 321, the first sealing portion 321 is away from the first blocking portion 23, and the first blocking portion 23 cannot seal the outlet 22, thereby forming a water outlet space, so that the liquid in the container body can flow out through the outlet 22.

[0088] In some embodiments, the first blocking portion 23 and the first sealing portion 321 are both substantially perpendicular to the central axis direction of the cover 10. The first blocking portion 23 and the first sealing portion 321 can be plate-shaped structures substantially perpendicular to the central axis direction of the cover 10 to better achieve the effect of blocking the movement of the suction nozzle 20 or allowing the liquid in the container body to flow out.

[0089] As shown in Figure 8 and Figure 10 In some embodiments, the sealing portion 32 further includes a second sealing portion 322 substantially parallel to the central axis direction of the cover 10 and a third sealing portion 323 having an obtuse angle with the second sealing portion 322, the second sealing portion 322 being connected between the first sealing portion 321 and the third sealing portion 323, and the suction nozzle 20 further includes a second blocking portion 24 substantially parallel to the central axis direction of the cover 10 and a third blocking portion 25 having an obtuse angle with the second sealing portion 322, the second blocking portion 24 being connected between the first blocking portion 23 and the third blocking portion 25, in the retracted state, the second sealing portion 322 is in contact with the second blocking portion 24, and the third sealing portion 323 is in contact with the third blocking portion 25.

[0090] By setting the second sealing portion 322 substantially parallel to the central axis of the cover body 10 and the second blocking portion 24 substantially parallel to the central axis of the cover body 10, and the second sealing portion 322 and the second blocking portion 24 are attached, the movement of the nozzle 20 relative to the inner plug 30 can be guided.

[0091] By setting the third sealing portion 323 and the third blocking portion 25 with an obtuse angle between the second sealing portion 322 and the third sealing portion 323, and the third sealing portion 323 and the third blocking portion 25 are attached, the effect of stably supporting the third blocking portion 25 by the third sealing portion 323 can be achieved, and the third sealing portion 323 can also limit the movement of the nozzle 20 relative to the inner plug 30.

[0092] Of course, the second sealing portion 322 and the second blocking portion 24 are attached, and the third sealing portion 323 and the third blocking portion 25 are attached, which can also enhance the sealing effect of the nozzle 20 and effectively prevent the nozzle 20 from leaking water.

[0093] As shown in Figure 17 In some embodiments, the outer periphery of the second blocking portion 24 is provided with a first protruding portion 241. The first protruding portion 241 extends radially from the outer surface of the second blocking portion 24 in a direction away from the second blocking portion 24.

[0094] By setting the first protruding portion 241, it is beneficial to realize the close contact between the second sealing portion 322 and the second blocking portion 24, prevent the surface of the second sealing portion 322 and the second blocking portion 24 from being unable to closely contact due to unevenness, and further cause sealing failure and water leakage problems.

[0095] The first protruding portion 241 can be an annular structure, or a plurality of independent structures arranged in a circumferential direction.

[0096] In some embodiments, the center of the sealing portion 32 is provided with a first through hole 324, and the nozzle 20 further includes a cooperating portion 26, the cooperating portion 26 is arranged in the first through hole 324, and the cooperating portion 26 is configured to limit the movement of the nozzle 20 relative to the inner plug 30 in the circumferential direction.

[0097] By setting the cooperating portion 26, the movement of the nozzle 20 relative to the inner plug 30 can be limited, the movement speed of the nozzle 20 relative to the inner plug 30 can be slowed down, the problem of being suddenly and quickly opened by the water flow can be avoided, and the consumer can feel that the nozzle 20 has a buffer movement, and the use experience of the consumer can be improved.

[0098] In some embodiments, the mating portion 26 includes a first mating portion 261 and a second mating portion 262 disposed on the outer periphery of the first mating portion 261. The diameter of the first mating portion 261 is less than or equal to the diameter of the first through hole 324, and the second mating portion 262 is configured to restrict the movement of the suction nozzle 20 relative to the inner plug 30 in the circumferential direction.

[0099] like Figure 17 and Figure 18 As shown, the diameter of the first mating part 261 is less than or equal to the diameter of the first through hole 324. When the portion of the first mating part 261 without the second mating part 262 is located within the first through hole 324 and the nozzle 20 moves within the length range of the first mating part 261, the movement of the nozzle 20 is relatively smooth, facilitating the nozzle 20 to quickly enter a state of small water output. However, after the second mating part 262 is provided, the diameter of the portion of the first mating part 261 with the second mating part 262 increases. When this portion is located within the first through hole 324 and the nozzle 20 moves within the length range of the second mating part 262, the nozzle 20 will experience a certain resistance. The friction between the second mating part 262 and the hole wall of the first through hole 324 will gradually increase, thereby reducing the movement speed of the nozzle 20, causing the water output to increase slowly, and preventing the rapid increase in water output from causing water flow impact on the consumer.

[0100] In some embodiments, the second mating portion 262 includes a first mating section near the first mating portion 261 and a second mating section away from the first mating portion 261. The diameter of the first mating section is less than or equal to the diameter of the first through hole 324, and the diameter of the first mating section gradually increases in the direction away from the first mating portion 261. The diameter of the second mating section is slightly larger than the diameter of the first through hole 324. A plurality of second mating portions 262 are arranged circumferentially spaced along the first mating portion 261, and a second through hole 271 that allows fluid to pass through is formed between two adjacent second mating portions 262.

[0101] The diameter of the first mating section is less than or equal to the diameter of the first through hole 324, and the diameter of the first mating section gradually increases in the direction away from the first mating part 261, so that the suction nozzle 20 can slowly enter the deceleration stage during the process of being pulled out; the diameter of the second mating section is slightly larger than the diameter of the first through hole 324, so that the movement of the suction nozzle 20 can be effectively slowed down.

[0102] In some embodiments, the outer periphery of the mating portion 26 is provided with a second protrusion 260. The second protrusion 260 extends radially away from the outer periphery of the mating portion 26.

[0103] When the second protrusion 260 passes the hole wall of the first through hole 324, the resistance to the suction nozzle 20 is obviously increased, and the pulling-out speed of the suction nozzle 20 is obviously slowed down, so that the movement stroke of the suction nozzle 20 can be prompted, and the consumer can be prompted that the suction nozzle 20 has been moved to the position of the second protrusion 260. For example, when the second protrusion 260 is arranged at the position adjacent to the end of the movement stroke of the suction nozzle 20, the consumer can be prompted that the suction nozzle 20 has been moved to the position close to the end, so that the consumer can be prepared to grasp the movement stroke of the suction nozzle 20, and avoid pulling out the suction nozzle 20 from the inner plug 30 completely by too much force.

[0104] In some embodiments, the second protrusion 260 can be arranged on the outer periphery of the second matching portion 262.

[0105] The second protrusion 260 can be a ring structure, or a plurality of independent structures arranged in a circumferential direction.

[0106] In some embodiments, the suction nozzle 20 comprises a first limiting portion 27 close to the connecting portion 17 and / or a second limiting portion 28 away from the connecting portion 17, the center of the sealing portion 32 is provided with a first through hole 324, the suction nozzle 20 is arranged in the first through hole 324, the first limiting portion 27 is configured to prevent the suction nozzle 20 from passing through the first through hole 324 and separating from the inner plug 30 in a direction away from the connecting portion 17, and the second limiting portion 28 is configured to cooperate with the end of the inner plug 30 away from the connecting portion 17 to prevent the suction nozzle 20 from falling into the third accommodating cavity 31 in a direction close to the connecting portion 17.

[0107] By arranging the first limiting portion 27 and / or the second limiting portion 28, the movement stroke of the suction nozzle 20 can be effectively limited, and the suction nozzle 20 can be prevented from separating from the inner plug 30 and being mistakenly swallowed by the consumer, so as to avoid safety accidents.

[0108] The outer portion of the first limiting portion 27 is larger than the diameter of the first through hole 324, so as to prevent the suction nozzle 20 from passing through the first through hole 324 and separating from the inner plug 30. Since the first through hole 324 is arranged on the sealing portion 32, the first limiting portion 27 is blocked by the third sealing portion 323 to prevent the suction nozzle 20 from passing through the first through hole 324 and separating from the inner plug 30.

[0109] In some embodiments, the second limiting portion 28 comprises a limiting segment and a clamping segment arranged on one side of the limiting segment away from the connecting portion 17, the diameter of the limiting segment is larger than the port diameter of the third accommodating cavity 31, so as to limit the movement of the suction nozzle 20 in a direction close to the connecting portion 17, the clamping segment extends outward in the radial direction of the inner plug 30 relative to the limiting segment, and there is a gap between the clamping segment and the end of the inner plug 30 away from the connecting portion 17.

[0110] By setting the diameter of the limiting section to be greater than the port diameter of the third accommodating cavity 31, the movement of the suction nozzle 20 in the direction of approaching the connecting portion 17 can be effectively limited, and the end portion of the inner plug 30 away from the connecting portion 17 is matched to prevent the suction nozzle 20 from falling into the third accommodating cavity 31 in the direction of approaching the connecting portion 17.

[0111] By setting the engaging section extending radially outward of the inner plug 30 relative to the limiting section, a structure facilitating the consumer to bite into the mouth can be formed, and there is a gap between the engaging section and the end portion of the inner plug 30 away from the connecting portion 17, which can facilitate the consumer to completely bite the engaging section and achieve the purpose of pulling out the suction nozzle 20 by slightly more force.

[0112] In some embodiments, the suction nozzle 20 is provided with a plurality of first limiting portions 27 arranged at intervals in the circumferential direction, and a second through hole 271 allowing fluid to pass is formed between adjacent two first limiting portions 27. The second through hole 271 is in communication with the first through hole 324.

[0113] By setting the second through hole 271, the first limiting portion 27 can prevent the first through hole 324 from being completely blocked, affecting the flow of water.

[0114] In some embodiments, the inner wall of the cover 10 is provided with a recess 14, and the inner plug 30 includes an inner plug body 33 and a protrusion 34 extending radially outward relative to the inner plug body 33, and the protrusion 34 is inserted into the recess 14 to realize the connection of the cover 10 and the inner plug 30.

[0115] By setting the recess 14 on the inner wall of the cover 10, the installation of the inner plug 30 can be facilitated. The installation mode of the protrusion 34 inserted into the recess 14 between the cover 10 and the inner plug 30 can also realize the isolation of the action on the first accommodating cavity 11 of the container body through the inner plug 30, so that the liquid in the container body enters the suction nozzle 20 through the third accommodating cavity 31 in the inner plug 30, and then flows out from the suction nozzle 20.

[0116] In some embodiments, the inner plug 30 includes a deformable portion configured to reduce the diameter of the inner plug 30 at the protrusion 34, so that the protrusion 34 can smoothly enter the recess 14.

[0117] By setting the deformable portion, the diameter of the inner plug 30 at the protrusion 34 can be reduced by being extruded when the protrusion 34 enters the recess 14, so that the protrusion 34 can smoothly enter the recess 14, and the installation convenience of the inner plug 30 is improved.

[0118] The deformable portion can be made of a compressible elastic material to facilitate the purpose of reducing the diameter of the inner plug 30 at the protrusion 34 after being extruded.

[0119] In some embodiments, the deformable portion includes a groove 35 having a space along the radial direction of the inner plug 30. By providing the groove 35, the deformable portion can be made compressible, thereby reducing the diameter of the inner plug 30 at the protrusion 34 after the deformable portion is compressed.

[0120] The protrusion 34 and the recess 14 can be a ring structure or multiple independent structures arranged at intervals along the circumference.

[0121] In some embodiments, the inner plug 30 has a third protrusion 36 extending toward the connection portion 17 on the side near the connection portion 17, and the third protrusion 36 is used to fit against the container body.

[0122] By providing the third protrusion 36, the inner plug 30 can be tightly fitted to the top of the container body, improving the sealing between the inner plug 30 and the container body and preventing liquid inside the container body from flowing out through the gap between the inner plug 30 and the container body.

[0123] The third protrusion 36 can be a ring structure or multiple independent structures arranged at intervals along the circumference.

[0124] like Figure 7 and Figure 8 As shown, in some embodiments, the inner plug body 33 includes a first body portion 331 and a second body portion 332. The diameter of the first body portion 331 is smaller than the diameter of the second body portion 332, and the second body portion 332 is disposed on the side of the first body portion 331 near the connecting portion 17. A protrusion 34 is disposed on the outer periphery of the second body portion 332 and extends radially away from the outer surface of the second body portion 332. The first body portion 331 and the second body portion 332 are provided with a through hole to form a third receiving cavity 31. A sealing portion 32 is disposed within the through hole of the first body portion 331.

[0125] In some embodiments, the container body further includes a hinge 15, the cover 10 includes an upper cover 12 and a lower cover 13, the inner plug 30 is installed on the lower cover 13, and the upper cover 12 and the lower cover 13 are connected by the hinge 15 so that the upper cover 12 can rotate relative to the lower cover 13, and the rotation angle is not less than 180°. For example, the rotation angle can be 60°, 90°, 120°, 180°, etc.

[0126] By setting the hinge 15, a rotatable connection can be achieved between the upper cover 12 and the lower cover 13, while also facilitating the adjustment of the opening angle of the upper cover 12 relative to the lower cover 13.

[0127] Hinge 15 can be made of plastic material, which makes it easy to adjust the angle and has a long service life.

[0128] In some embodiments, the hinge 15 is configured to enable the upper cover 12 and the lower cover 13 to be kept at a preset angle, such as 90°, 180°, etc. Such a setting can keep the angle of the upper cover 12 and the lower cover 13 relatively fixed, preventing the upper cover 12 from turning back relative to the lower cover 13 when the user is drinking water, thereby affecting the use experience.

[0129] As shown in FIG. 1, the angle between the upper cover 12 and the lower cover 13 is kept at 90°; as shown in FIG. 2, the angle between the upper cover 12 and the lower cover 13 is kept at 180°. Figures 19 to 22 Figures 23 to 26 As shown in FIG. 1, the angle between the upper cover 12 and the lower cover 13 is kept at 90°; as shown in FIG. 2, the angle between the upper cover 12 and the lower cover 13 is kept at 180°.

[0130] In some embodiments, the cover body 10 includes the upper cover 12 and the lower cover 13, and the inside of the upper cover 12 is provided with a pressing structure configured to form a pressure on the suction nozzle 20 to make the suction nozzle 20 return to the retracted state during the process of the upper cover 12 being covered on the lower cover 13.

[0131] By providing the pressing structure, a certain downward pressure can be formed on the suction nozzle 20, so that the suction nozzle 20 can also automatically return to the retracted state after the upper cover 12 is covered on the lower cover 13, preventing the upper cover 12 from being unable to be covered due to the suction nozzle 20 not being retracted. At the same time, forcing the suction nozzle 20 to retract by using the pressing structure can also avoid the problem of unhygienic use caused by the user manually retracting the suction nozzle 20 with the hand.

[0132] In some embodiments, the cover body 10 further includes a second sealing ring installed on the end of the lower cover 13 close to the upper cover 12, and the end of the upper cover 12 close to the lower cover 13 is provided with a plurality of second connection bridge points arranged in a circumferential direction, and the upper cover 12 is connected to the second sealing ring on the lower cover 13 through the second connection bridge points.

[0133] By providing the second sealing ring, the sealing performance of the connection between the upper cover 12 and the lower cover 13 can be effectively maintained, preventing the liquid in the container from being contaminated.

[0134] In some embodiments, the upper cover 12 is provided with an opening cover portion 16 recessed inward from the outer surface of the upper cover 12, facilitating the user's finger to enter the opening cover portion 16 to exert force to open the upper cover 12.

[0135] In some embodiments, the suction nozzle 20 further includes a shaped portion 29 arranged in the second accommodating cavity 21, and the shaped portion 29 has a gap with the inner wall of the second accommodating cavity 21, and the shaped portion 29 is configured in a preset shape.

[0136] By providing the gap between the shaped portion 29 and the inner wall of the second accommodating cavity 21, the shaped portion 29 can be prevented from affecting the outflow of the liquid.

[0137] ​The modeling part 29 can be arranged in the suction nozzle 20 close to the end, so that the consumer can see it when opening the upper cover 12, improving the interest of the container cover and pleasing the consumer's mood.

[0138] The second accommodating cavity 21 can be provided with a supporting part for supporting the modeling part 29, and the supporting part can be connected to the second blocking part 24 or the third blocking part 25.

[0139] As shown in the drawings, in some embodiments, the preset shape includes a five-pointed star, a shape representing a preset animal, or a shape representing a preset constellation. For example, a shape representing a rabbit, a shape representing a certain cartoon image, a shape representing a white sheep constellation, a crab constellation, etc. Figures 14 to 16

[0141] As shown in the drawings, the container cover includes a cover body 10, a suction nozzle 20, and an inner plug 30. Figures 1 to 3 As shown in the drawings, the cover body 10 includes an upper cover 12 and a lower cover 13, and the inner space of the upper cover 12 and the lower cover 13 together forms a first accommodating cavity 11. The central axis of the first accommodating cavity 11 is parallel to the height direction of the container body. The cover body 10, the suction nozzle 20, and the inner plug 30 are coaxially arranged.

[0142] Figures 4 to 6 The inner wall of the lower cover 13 is provided with a connecting part 17 (such as an inner thread), and the neck of the container body is provided with an outer thread. The container body is screwed into the inside of the lower cover 13 through the cooperation of the outer thread and the inner thread, so as to achieve the purpose of sealing the container body by the container cover. The container body is provided with a first sealing ring, and the bottom edge of the lower cover 13 is provided with a plurality of first connecting bridge points. The lower cover 13 is connected to the first sealing ring through the first connecting bridge points. When the container cover is rotated, the first connecting bridge points are damaged, and the container cover can be integrally detached from the container body.

[0143] The position close to the upper cover 12 of the lower cover 13 is also provided with a second sealing ring, and the position close to the lower cover 13 of the upper cover 12 is provided with a second connecting bridge point. The upper cover 12 is sealingly connected to the lower cover 13 through the second connecting bridge point. The upper cover 12 is provided with a recessed cover opening part 16. The user inserts his fingers into the cover opening part 16 and slightly forces upward to damage the second connecting bridge point, so as to open the upper cover 12.

[0144] The position close to the upper cover 12 of the lower cover 13 is also provided with a second sealing ring, and the position close to the lower cover 13 of the upper cover 12 is provided with a second connecting bridge point. The upper cover 12 is sealingly connected to the lower cover 13 through the second connecting bridge point. The upper cover 12 is provided with a recessed cover opening part 16. The user inserts his fingers into the cover opening part 16 and slightly forces upward to damage the second connecting bridge point, so as to open the upper cover 12.

[0145] ​​The upper cover 12 and the lower cover 13 are also connected by a hinge 15, which is arranged substantially opposite to the cover opening part 16. After the upper cover 12 is opened, the hinge 15 can keep the upper cover 12 and the lower cover 13 at an angle of 90°, 120°, 150° or 180°, so as to avoid the upper cover 12 returning to the closed position when drinking water, which affects the drinking experience.

[0146] The inner wall of the lower cover 13 is provided with a recess 14 near the upper cover 12, and the recess 14 is used to fix the inner plug 30.

[0147] As shown in Figure 7 and Figure 8 The inner plug 30 includes an inner plug body 33, and the inner plug body 33 includes a first body part 331 and a second body part 332. Both the first body part 331 and the second body part 332 are hollow cylindrical structures, and the diameter of the first body part 331 is smaller than that of the second body part 332. The inner space of the first body part 331 and the inner space of the second body part 332 together form a third accommodating cavity 31. The diameter of the third accommodating cavity 31 is designed to be equal in the axial direction. The inner wall of the third accommodating cavity 31 is provided with a sealing part 32, which includes a first sealing part 321 perpendicular to the central axis of the first accommodating cavity 11, a second sealing part 322 parallel to the central axis of the first accommodating cavity 11, and a third sealing part 323 inclined relative to the central axis of the first accommodating cavity 11. The included angle between the second sealing part 322 and the third sealing part 323 is obtuse. The center of the sealing part 32 is provided with a first through hole 324, and the first sealing part 321, the second sealing part 322 and the third sealing part 323 are all annular structures arranged in the circumferential direction. The shape of the third sealing part 323 has the functions of supporting the mouthpiece 20 upwardly and limiting the mouthpiece 20.

[0148] The outer periphery of the second body part 332 is provided with a protruding part 34 protruding outwardly in the radial direction, and the protruding part 34 is inserted into the recess 14 of the lower cover 13, so as to fix the inner plug 30 in the cover body 10.

[0149] The second body part 332 or the protruding part 34 is provided with a groove 35, so that when the second body part 332 or the protruding part 34 is subjected to radial extrusion, the overall diameter of the inner plug 30 can be reduced, so that the protruding part 34 on the inner plug 30 can smoothly enter the recess 14.

[0150] The end of the second body part 332 away from the first body part 331 is provided with a third protruding part 36, which is in close contact with the top end face of the container body, so as to improve the sealing between the container cover and the container body, and prevent water leakage.

[0151] The inner wall of the third accommodating cavity 31 can also be provided with reinforcing ribs, so as to improve the structural strength of the inner plug 30.

[0152] AsFigures 9 to 13 As shown, the suction nozzle 20 comprises an upper section and a lower section, and the inner space of the upper section and the inner space of the lower section together form the second accommodating cavity 21. The upper section is in the shape of a hollow cylinder, and the lower section is in the shape of a hollow variable-diameter cylinder. The outer diameter of the upper section is greater than the outer diameter of the lower section, and the diameter of the inner space of the upper section is also greater than the diameter of the inner space of the lower section. The bottom of the inner space of the lower section is closed. The bottom of the upper section is radially protruding from the portion of the lower section, and a plurality of spaced-apart outlets 22 are arranged on the bottom of the upper section, and the portion between any two adjacent outlets 22 forms a first blocking portion 23. The first blocking portion 23 is perpendicular to the central axis of the first accommodating cavity 11.

[0153] The lower section comprises, in sequence in the direction away from the upper section, a second blocking portion 24 parallel to the central axis of the first accommodating cavity 11, a third blocking portion 25 arranged obliquely relative to the central axis of the first accommodating cavity 11, a fitting portion 26, and a first limiting portion 27. The included angle between the third blocking portion 25 and the second blocking portion 24 is obtuse, and the included angle between the second sealing portion 322 and the third sealing portion 323 is equal to the included angle between the third blocking portion 25 and the second blocking portion 24, so that the second sealing portion 322 can be in contact with the second blocking portion 24 and the third sealing portion 323 can be in contact with the third blocking portion 25 when sealing.

[0154] The fitting portion 26 comprises a first fitting portion 261 connected to the third blocking portion 25, and a plurality of second fitting portions 262. The inner cavity of the first fitting portion 261 is in communication with the inner cavities of the third blocking portion 25, the second blocking portion 24, and the upper section to form the second accommodating cavity 21. Moreover, the bottom of the inner cavity of the first fitting portion 261 is closed. The first fitting portion 261 is a constant-diameter section, and the diameter of the first fitting portion 261 is less than or equal to the diameter of the first through hole 324. The plurality of second fitting portions 262 are arranged at intervals in the circumferential direction on the outer periphery of the first fitting portion 261, and the portion between any two adjacent second fitting portions 262 forms a second through hole 271 allowing fluid to pass through. The first limiting portion 27 is arranged at the end of the second fitting portion 262 close to the connecting portion 17, and the circumferential length of the first limiting portion 27 is not greater than the circumferential length of the second fitting portion 262, so that the portion between any two adjacent first limiting portions 27 also forms a second through hole 271 allowing fluid to pass through.

[0155] The end of the upper section of the suction nozzle 20 is provided with a second limiting portion 28, which can prevent the suction nozzle 20 from falling completely into the third accommodating cavity 31 of the inner plug 30. Moreover, there is a gap between the second limiting portion 28 and the end of the inner plug 30, which can allow the user's teeth to enter so as to bite the suction nozzle 20, thereby facilitating the user to pull out the suction nozzle 20 with the teeth.

[0156] As Figures 14 to 16As shown, the inner part of the second accommodating cavity 21 of the inner plug 30 is provided with a support part extending upward from the joint of the second blocking part 24 and the third blocking part 25, and the top of the support part is provided with a shaped part 29 in the shape of a five-pointed star. In other embodiments, the shaped part 29 can also be in the shape of an animal, a constellation, a cartoon image, etc.

[0157] Reference Figure 3 As shown, when the container cover is in the closed state, the suction nozzle 20 is not pulled up, the first blocking part 23 of the suction nozzle 20 is in contact with the first sealing part 321 of the inner plug 30, the outlet 22 is completely blocked by the first sealing part 321, the second blocking part 24 is in contact with the second sealing part 322, the third blocking part 25 is in contact with the third sealing part 323, and the third accommodating cavity 31 is not in communication with the second accommodating cavity 21.

[0158] As Figure 17 shown, a schematic diagram of the state in which the suction nozzle 20 is slightly pulled up, at this time, the first blocking part 23 is away from the first sealing part 321, the outlet 22 is in an open state, and there are gaps between the second blocking part 24 and the second sealing part 322 and between the third blocking part 25 and the third sealing part 323. Therefore, the third accommodating cavity 31 and the second accommodating cavity 21 can be communicated through these gaps and the outlet 22, so that the liquid in the container body can flow out through the suction nozzle 20.

[0159] As Figure 18 shown, the suction nozzle 20 is completely pulled out, at this time, the first blocking part 23 is further away from the first sealing part 321, the gaps between the second blocking part 24 and the second sealing part 322 and between the third blocking part 25 and the third sealing part 323 are further increased, and the water output of the suction nozzle 20 is gradually increased. At this time, the first limiting part 27 is blocked by the third sealing part 323, which can prevent the suction nozzle 20 from being separated from the inner plug 30.

[0160] As Figure 19 and Figure 20 shown, the suction nozzle 20 is not pulled out, and the included angle between the upper cover 12 and the lower cover 13 is kept at 90°; as Figure 21 and Figure 22 shown, the suction nozzle 20 is pulled out, and the included angle between the upper cover 12 and the lower cover 13 is kept at 90°; as Figure 23 and Figure 24 shown, the suction nozzle 20 is not pulled out, and the included angle between the upper cover 12 and the lower cover 13 is kept at 180°; as Figure 25 and Figure 26 shown, the suction nozzle 20 is pulled out, and the included angle between the upper cover 12 and the lower cover 13 is kept at 180°.

[0161] When the container cover is installed on the container body to form a container, the upper cover 12 can be opened first when the container is used to drink water, and then the container body is tilted to facilitate the alignment of the mouth of the consumer with the suction nozzle 20, and at the same time, the suction nozzle 20 is bitten on the bite section on the second limiting portion 28 of the suction nozzle 20, and the suction nozzle 20 is pulled out with a little force. After the suction nozzle 20 is pulled out, the suction nozzle 20 moves outward relative to the inner plug 30, the third sealing portion 323 on the suction nozzle 20 moves away from the third blocking portion 25 on the inner plug 30, the second sealing portion 322 on the suction nozzle 20 moves outward relative to the second blocking portion 24 on the inner plug 30, and the first sealing portion 321 on the suction nozzle 20 moves away from the first blocking portion 23 on the inner plug 30, so that the outlet 22 is opened. The liquid in the container body first enters the third containing cavity 31, then enters the space on the other side of the sealing portion 32 through the second through hole 271 formed between the two first limiting portions 27 and the first through hole 324 provided on the sealing portion 32, and then enters the second containing cavity 21 of the suction nozzle 20 through the outlet 22, and finally flows out from the top opening of the second containing cavity 21. After drinking water, even if the suction nozzle 20 is in the pulled-out state, the upper cover 12 can be directly closed. The pressurization structure in the upper cover 12 can force the suction nozzle 20 to automatically return to the retracted state, and the sealing of the container is maintained after the upper cover 12 is closed, effectively preventing foreign matter from entering.

[0162] The suction nozzle in the container cover provided by the application adopts a structure design of moving up and down along the central axis of the cover body, which can increase the fun of drinking, and the pulled-out suction nozzle can also provide comfort for drinking. The first limiting portion and the second limiting portion are respectively arranged at the two ends of the suction nozzle, which can prevent the suction nozzle from being completely pulled out when children drink, causing mis-swallowing. The hinge connection between the upper cover and the lower cover can realize the relative rotation of the upper cover and the lower cover, and can keep the upper cover and the lower cover at a predetermined angle, preventing the upper cover from turning back to affect the drinking experience when drinking water. The sealing ring arranged between the upper cover and the lower cover effectively improves the sealing performance of the container cover. The shaped portion arranged in the suction nozzle improves the entertainment of children during drinking. The second limiting portion includes a bite section, which is convenient for teeth to bite and achieves the purpose of easily pulling out the suction nozzle, avoiding the pollution caused by the contact of hands with the suction nozzle, and improving the use convenience of the product. After drinking, the cover can be directly closed, and the pulled-out suction nozzle can be pressed into place by the pressurization structure at the top of the upper cover, without the need for manual pressing of the suction nozzle, reducing the pollution of the nipple suction nozzle, and improving the convenience of drinking.

[0163] Based on the above container cover, the application further provides a container, which comprises a container body and the above container cover, and the container cover is sealed to the opening of the container body through the connecting portion 17.

[0164] The positive technical effects of the container cover in each of the above embodiments are also applicable to the container, which will not be described here.

[0165] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit it; although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the specific embodiments of the present application can be modified or some technical features can be replaced equivalently without departing from the principles of the present application, and these modifications and equivalent replacements should be covered in the technical solution range claimed by the present application.
