Description

Technical Field

[0001] The utility model relates to the technical field of liquid containers, in particular to a container cover and a liquid container. Background Art

[0002] At present, portable water cups for going out such as sports water cups are usually equipped with a button for one - hand operation to open and close the upper cover. However, during the use of the water cup, the upper cover may be accidentally opened because the user forgets to lock it, which may easily cause problems such as scalding the user or wetting clothes, reducing the user experience. Summary of the Utility Model

[0003] This application provides a container cover and a liquid container to solve the problem that the existing water cup cannot be automatically locked and is easily accidentally opened.

[0004] In the first aspect of this application, a container cover and a liquid container are provided. The container cover includes an upper cover, a lower cover, a button assembly, and a first elastic member. The upper cover includes a first mating portion. The upper cover is rotatably connected to the lower cover. The button assembly is connected to the lower cover, and the button assembly is provided with a second mating portion for locking and mating with the first mating portion. The button assembly includes a limit key, and the limit key can move relative to the lower cover so that the limit key is in a locked position or an unlocked position. The first elastic member is installed on the lower cover and is connected to the button assembly.

[0005] Wherein, in the locked position, the limit key is used to restrict the first mating portion and the second mating portion from releasing the locking and mating. In the unlocked position, the limit key releases the restriction on the first mating portion and the second mating portion, so that the first mating portion and the second mating portion can release the locking and mating.

[0006] The first elastic member is used to drive the button assembly to return to the locked position.

[0007] In this solution, the limit key can be automatically reset from the unlocked position to the locked position through the first elastic member. After the user closes the upper cover, the upper cover and the lower cover maintain a mutually locked state under the restriction of the limit key, reducing the risk that the upper cover is accidentally opened due to the user accidentally touching the button assembly, reducing the risk of scalding or wetting clothes, improving the use safety of the container cover, and thus improving the user experience.

[0008] In this solution, the first elastic member is a torsion spring. Along the height direction of the container cover, the limit key has a stepped portion, and the first elastic member has an extension section, and the extension section is connected to the stepped portion.

[0009] In this solution, when the limit key switches from the locked position to the unlocked position under the action of an external force, the limit key drives the extension section of the first elastic member to move through the stepped portion, compressing the first elastic member. When the external force is removed, under the action of the resilience of the first elastic member, the limit key is driven by the extension section to move to the locked position to lock the container lid. Therefore, the container lid can be automatically locked through the first elastic member without manual operation by the user, improving the convenience of user use.

[0010] In this solution, the limit key can rotate relative to the lower cover and can move along the height direction of the container lid relative to the lower cover so that the limit key is in the locked position or the unlocked position.

[0011] In the locked position, the limit key abuts against the lower cover to limit the rotation of the limit key and prevent the first engaging portion and the second engaging portion from releasing the locking engagement. In the unlocked position, the limit key is disengaged from the lower cover so that the limit key can rotate, enabling the first engaging portion and the second engaging portion to release the locking engagement.

[0012] In this solution, switching the position of the limit key requires applying a force along the height direction of the container lid and driving the limit key to rotate, greatly reducing the risk of the limit key moving to the unlocked position due to accidental touch by the user, thereby reducing the risk of the container lid being accidentally opened and improving the use safety.

[0013] In this solution, the key assembly further includes a locking key. The limit key is located outside the locking key. The second engaging portion is provided on the locking key. The locking key is rotatably connected to the lower cover.

[0014] In this solution, the locking key of the key assembly is used to cooperate or release cooperation with the upper cover. When the limit key is in the locked position, the locking key cannot rotate. The limit key restricts the locking key to the state of cooperating with the upper cover to prevent the upper cover from being accidentally opened. When the limit key is in the unlocked position, the locking key can rotate, enabling the locking key to rotate to the state of cooperating with the upper cover or the state of releasing cooperation.

[0015] In this solution, in the locked position, there is a gap between the locking key and the limit key along the radial direction of the container lid so that the locking key can rotate relative to the limit key during the locking engagement of the first engaging portion and the second engaging portion, causing elastic deformation of the first elastic member.

[0016] In this solution, due to the gap between the locking key and the limit key along the radial direction of the container lid, when the limit key is in the locked position, the first engaging portion can automatically lock and engage with the second engaging portion in place without separate operation by the user, improving the convenience of closing the container lid.

[0017] In this solution, along the radial direction of the container cover, the size of the gap is L1, and the matching size of the first matching portion and the second matching portion when locked is L2, and L1<L2.

[0018] In this scheme, the size L1 of the gap between the locking key and the limit key can be smaller than the fitting size L2 when the first fitting part and the second fitting part are locked together, that is, the distance that the second fitting part can rotate is smaller than the size of the locking fit between the first fitting part and the second fitting part. When the first fitting part and the second fitting part are locked together, the first fitting part and the second fitting part can be squeezed against each other in the radial direction, thereby further improving the stability and reliability of the locking fit between the first fitting part and the second fitting part.

[0019] In this embodiment, the lower cover is provided with a first rotating shaft, the locking key is rotatably connected to the first rotating shaft, and the first elastic member is sleeved on the first rotating shaft. The limit key has a sliding groove extending along the height direction of the container cover, and the limit key is rotatably connected to the first rotating shaft through the sliding groove.

[0020] In this solution, the first rotating shaft is sleeved with the first elastic member, the locking key may be provided with a connecting hole, so that the first rotating shaft can be rotatably connected with the locking key through the connecting hole, and the limit key is provided with a sliding groove extending in the height direction of the container cover, so that the first rotating shaft can be rotatably connected with the limit key through the sliding groove, so that the limit key and the locking key can rotate relative to the lower cover. At the same time, the sliding groove extends in the height direction of the container cover, so that the limit key can not only rotate relative to the lower cover, but also move relative to the lower cover along the height direction of the container cover, thereby improving the feasibility of switching the limit key between the locked position and the unlocked position.

[0021] In this solution, the container cover further includes a second elastic member, and along the radial direction of the container cover, the second elastic member is elastically connected to the locking key and the lower cover.

[0022] In this solution, the second elastic member connected between the lower cover and the locking key enables the locking key and the limit key to automatically rotate relative to the lower cover, so that the second matching portion can automatically reset to a position where it is locked and matched with the first matching portion, so that in the process of closing the upper cover, the first matching portion and the second matching portion are locked and matched, so that the container cover can be automatically locked without the need for manual locking by the user. Therefore, the second elastic member can promote the limit key to automatically return to the locked position, further preventing the upper cover from being opened by mistake due to the limit key being unable to lock the locking key.

[0023] In this embodiment, the lower cover has a blocking portion extending in the direction of the limit key, and the limit key has an abutment portion extending in the direction of the lower cover. In the locked position, the abutment portion abuts against the blocking portion, and in the unlocked position, the abutment portion is located on the side of the blocking portion away from the upper cover.

[0024] In this solution, when the limit key is in the locked position, it abuts against the blocking part through the abutting part to limit the rotation of the limit key relative to the lower cover, reducing the risk that the user accidentally touches it and causes the unlocking fit between the first mating part and the second mating part, improving the reliability and stability of the connection between the first mating part and the second mating part, and thus improving the reliability and stability of the container lid in the closed state. The abutting part and the blocking part can facilitate the abutment of the limit key and the lower cover, so as to facilitate the limit key to be in the locked position.

[0025] In this solution, the first mating part can be snap-fitted with the second mating part.

[0026] In this solution, when the first mating part and the second mating part are snap-fitted, the upper cover and the lower cover are snap-fitted through the button assembly to limit the opening of the upper cover. Therefore, the snap-fitting method is beneficial to improving the reliability of the locking fit between the first mating part and the second mating part, and thus improving the reliability and stability of the upper cover maintaining the state of being closed on the lower cover.

[0027] In the second aspect of the present application, a liquid container includes a container body and a container lid, and the container lid is installed on the container body. Among them, the container lid is the container lid described above.

[0028] In this solution, the container lid is threadedly connected to the container body through the lower cover. When the container lid is used for the container body, the limit key of the container lid can automatically reset from the unlocked position to the locked position, so that after the user closes the upper cover, the upper cover and the lower cover are relatively fixed under the restriction of the limit key, enabling the container lid to be automatically locked, reducing the risk that the user accidentally touches the button assembly and causes the upper cover to be accidentally opened, avoiding the risk of the liquid in the container body flowing out, thereby reducing the risk of scalding the user or wetting the clothes, improving the use safety of the liquid container, and further improving the user experience of using the liquid container.

[0029] It should be understood that the above general description and the following detailed description are only exemplary and cannot limit the present application. Description of the Drawings

[0063] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0064] In a specific embodiment, the present application will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0068] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the angles shown in the accompanying drawings and should not be construed 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 "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0069] The embodiments of the present application provide a container lid 1 that can be closed on the container body 2. As Figure 1 and Figure 2As shown, the container lid 1 includes an upper lid 11, a lower lid 12, and a button assembly 13. Among them, the upper lid 11 is rotatably connected to the lower lid 12, the button assembly 13 is connected to the lower lid 12, the container lid 1 is covered on the container body 2 through the lower lid 12, the container lid 1 can be locked with the container body 2, and the button assembly 13 can release the lock between the container lid 1 and the container body 2, enabling the container lid 1 to open the inner cavity of the container body 2.

[0070] As Figure 3 shown, the upper lid 11 includes a first mating portion 111, and the button assembly 13 is provided with a second mating portion 121 for locking and mating with the first mating portion 111. When the first mating portion 111 and the second mating portion 121 are locked and mated, the upper lid 11 and the lower lid 12 are mated through the button assembly 13 to restrict the opening of the upper lid 11. The first mating portion 111 and the second mating portion 121 are locked and mated by means of snap connection or buckle connection. The button assembly 13 includes a limit key 131, and the limit key 131 can move relative to the lower lid 12 so that the limit key 131 is in a locked position or an unlocked position. Among them, in the locked position, the limit key 131 is used to restrict the release of the locking and mating between the first mating portion 111 and the second mating portion 121, making the upper lid 11 unable to open. In the unlocked position, the limit key 131 releases the restriction on the first mating portion 111 and the second mating portion 121, enabling the first mating portion 111 and the second mating portion 121 to release the locking and mating, and the upper lid 11 can be opened.

[0071] The container lid 1 further includes a first elastic member 14. The first elastic member 14 is installed on the lower lid 12 and connected to the button assembly 13. The first elastic member 14 is used to drive the button assembly 13 to return to the locked position.

[0072] When the user needs to open the upper lid 11, drive the limit key 131 to move to the Figure 3 unlocked position as described above. During this process, the first elastic member 14 is elastically deformed. When the limit key 131 is in the unlocked position, the first mating portion 111 and the second mating portion 121 can release the locking and mating, thereby releasing the restriction on the relative rotation of the upper lid 11 and the lower lid 12, and the upper lid 11 can rotate relative to the lower lid 12, so that the container lid 1 is in an open state.

[0073] After canceling the external force applied to the limit key 131, the limit key 131 can automatically move to the Figure 4 locked position as described above under the action of the restoring force of the first elastic member 14. When the user needs to cover and lock the upper lid 11, only need to drive the upper lid 11 to rotate towards the lower lid 12, so that the first mating portion 111 and the second mating portion 121 can be automatically locked and mated under the action of the button assembly 13, thereby restricting the relative rotation of the upper lid 11 and the lower lid 12, so that the container lid 1 is in a covered state.

[0074] Therefore, the limit key 131 can be automatically reset from the unlocked position to the locked position through the first elastic member 14, so that after the user closes the upper cover 11, the upper cover 11 and the lower cover 12 maintain a mutually locked state under the restriction of the limit key 131, thereby reducing the risk of the user accidentally touching the button assembly 13 and causing the upper cover 11 to be accidentally opened, reducing the risk of causing burns or wetting clothes, improving the safety of using the container cover 1, and thereby improving the user experience.

[0075] In a possible implementation, Figure 3 and Figure 4 As shown, the first matching portion 111 can be engaged with the second matching portion 121. When the first matching portion 111 is engaged with the second matching portion 121, the upper cover 11 is engaged with the lower cover 12 through the key assembly 13 to restrict the upper cover 11 from opening. Therefore, the engagement is conducive to improving the reliability of the locking engagement between the first matching portion 111 and the second matching portion 121, thereby improving the reliability and stability of the upper cover 11 maintaining the state of covering the lower cover 12.

[0076] In a possible implementation, Figure 4 As shown, the side of the container cover 1 facing away from the button assembly 13 may include a second rotating shaft 19, and the upper cover 11 and the lower cover 12 are rotatably connected via the second rotating shaft 19. A third elastic member 16 may be provided on the second rotating shaft 19, and when the first matching portion 111 and the second matching portion 121 are released from the locking match, the third elastic member 16 causes the upper cover 11 to automatically rotate upward, so that the container cover 1 can be automatically opened.

[0077] In a possible implementation, Figure 2 , Figure 5 and Figure 6 As shown, the first elastic member 14 is a torsion spring. Along the height direction of the container cover 1, the limit key 131 has a step portion 131a, and the first elastic member 14 has an extension section 141, which is connected to the step portion 131a.

[0078] When the limit key 131 switches from the locked position to the unlocked position under the action of an external force, the limit key 131 drives the extension section 141 of the first elastic member 14 to move through the step portion 131a, so that the first elastic member 14 is compressed. When the external force is removed, under the action of the rebound force of the first elastic member 14, the limit key 131 is driven to move to the locked position through the extension section 141, so that the container cover 1 is locked. Therefore, the container cover 1 can be automatically locked through the first elastic member 14 without manual operation by the user, thereby improving the convenience of use for the user.

[0079] The step portion 131 a and the extension section 141 may be connected by bonding, welding, abutting, etc., and the present application does not limit the connection method between the step portion 131 a and the extension section 141 .

[0080] In a possible implementation, as Figure 5 and Figure 6 shown, the limit key 131 can rotate relative to the lower cover 12 and can move along the height direction of the container lid 1 relative to the lower cover 12, so that the limit key 131 is in a locked position or an unlocked position.

[0081] In the locked position, the limit key 131 abuts against the lower cover 12 to limit the rotation of the limit key 131 and to limit the unlocking of the first engaging portion 111 and the second engaging portion 121. In the unlocked position, the limit key 131 is disengaged from the lower cover 12, so that the limit key 131 can rotate, enabling the first engaging portion 111 and the second engaging portion 121 to be disengaged from the locked engagement.

[0082] When the limit key 131 needs to move from the locked position to the unlocked position, along the height direction of the container lid 1, the user needs to push the limit key 131 downward so that the limit key 131 moves downward and is disengaged from the lower cover 12. Then, the user can press the limit key 131 in the direction of the lower cover 12 so that the limit key 131 can rotate. At this time, the limit key 131 is in the unlocked position, enabling the first engaging portion 111 and the second engaging portion 121 to be disengaged from the locked engagement.

[0083] When the limit key 131 needs to move from the unlocked position to the locked position, the external force applied to the limit key 131 is cancelled. Then, the limit key 131 can rotate and move upward along the height direction of the container lid 1 under the restoring force of the first elastic member 14, that is, the limit key 131 can be restored to the position where the limit key 131 abuts against the lower cover 12 under the restoring force of the first elastic member 14, thereby restricting the rotation of the limit key 131 and restricting the unlocking of the first engaging portion 111 and the second engaging portion 121, so that the upper cover 11 and the button assembly 13 are maintained in a mating state, reducing the risk of accidental opening of the upper cover 11.

[0084] Therefore, switching the position of the limit key 131 requires applying a force along the height direction of the container lid 1 and driving the rotation of the limit key 131, greatly reducing the risk of the limit key 131 moving to the unlocked position due to accidental touch by the user, thereby reducing the risk of accidental opening of the container lid 1 and improving the use safety. At the same time, since the limit key 131 is rotatably connected to the lower cover 12, and during the process of the limit key 131 rotating from the unlocked position to the locked position, the first elastic member 14 can be deformed. Since the first elastic member 14 is a torsion spring, the restoring force of the first elastic member 14 can provide a torque to drive the rotation of the limit key 131, so that the limit key 131 is restored to the locked position.

[0085] Specifically, in a possible implementation, as Figure 5 and Figure 6As shown, the lower cover 12 has a blocking portion 123a extending toward the limit key 131, and the limit key 131 has an abutment portion 131b extending toward the lower cover 12. In the locked position, the abutment portion 131b abuts against the blocking portion 123a, and in the unlocked position, the abutment portion 131b is located on the side of the blocking portion 123a that is away from the upper cover 11.

[0086] In this embodiment, when the limit key 131 is in the locked position, the abutting portion 131b abuts against the blocking portion 123a to limit the rotation of the limit key 131 relative to the lower cover 12, thereby reducing the risk of the first matching portion 111 and the second matching portion 121 being released from the locked match due to a user's accidental touch, improving the reliability and stability of the connection between the first matching portion 111 and the second matching portion 121, and thus improving the reliability and stability of the container cover 1 in the closed state. The abutting portion 131b and the blocking portion 123a can facilitate the abutment of the limit key 131 with the lower cover 12, thereby facilitating the limit key 131 to be in the locked position.

[0087] In a possible implementation, Figure 5 and Figure 6 As shown, the button assembly 13 further includes a locking key 132 , the limit key 131 is located outside the locking key 132 , the second matching portion 121 is disposed on the locking key 132 , and the locking key 132 is rotatably connected to the lower cover 12 .

[0088] In this embodiment, during the movement of the limit key 131 between the locked position and the unlocked position, the limit key 131 rotates relative to the lower cover 12, thereby driving the lock key 132 located on the inner side to rotate, so that the second matching portion 121 located on the lock key 132 can be locked or unlocked with the first matching portion 111, which is conducive to improving the reliability of driving the second matching portion 121 to move and improving the reliability of the container cover 1 switching between the open and closed states. Therefore, in this embodiment, the lock key 132 of the button assembly 13 is used to match or unlock with the upper cover 11. When the limit key 131 is in the locked position, the lock key 132 cannot rotate. The lock key 132 is limited to the state of matching with the upper cover 11 by the limit key 131 to prevent the upper cover 11 from being opened by mistake. When the limit key 131 is in the unlocked position, the lock key 132 can rotate, so that the lock key 132 can be rotated to the state of matching with the upper cover 11 or the state of unlocking.

[0089] In a possible implementation, Figure 2 and Figure 5 As shown, the container cover 1 may further include a second elastic member 15 , and along the radial direction of the container cover 1 , the second elastic member 15 is elastically connected to the locking key 132 and the lower cover 12 .

[0090] When the limit key 131 needs to move to the unlocking position, push the limit key 131 downward so that the limit key 131 moves downward along the height direction of the container lid 1, causing the first elastic member 14 to be compressed. As a result, the key assembly 13 is disengaged from abutting against the lower lid 12. Subsequently, press the lower part of the limit key 131 in the radial direction of the container lid 1 towards the lower lid 12. Then, the limit key 131 drives the locking key 132 to rotate together towards the lower lid 12, and the second elastic member 15 is compressed, causing the second engaging portion 121 to rotate away from the first engaging portion 111, thereby releasing the locking engagement between the first engaging portion 111 and the second engaging portion 121.

[0091] When the limit key 131 needs to move to the locking position, after canceling the external force applied to the limit key 131, in the radial direction of the container lid 1, the limit key 131 and the locking key 132 can rotate together away from the lower lid 12 under the action of the restoring force of the second elastic member 15. At the same time, the limit key 131 can automatically move upward to the locking position under the action of the restoring force of the first elastic member 14. Then, the blocking portion 123a abuts against the abutting portion 131b, and the second engaging portion 121 rotates towards the first engaging portion 111, so that the second engaging portion 121 moves to the position where it is in locking engagement with the first engaging portion 111.

[0092] Through the second elastic member 15 connected between the lower lid 12 and the locking key 132, the locking key 132 and the limit key 131 can automatically rotate relative to the lower lid 12, so that the second engaging portion 121 can automatically return to the position where it is in locking engagement with the first engaging portion 111. This facilitates the locking engagement between the first engaging portion 111 and the second engaging portion 121 when closing the upper lid 11, enabling the container lid 1 to be automatically locked without the user having to lock it manually. Therefore, the second elastic member 15 can promote the automatic return of the limit key 131 to the locking position, further preventing the upper lid 11 from being accidentally opened due to the limit key 131 being unable to lock the locking key 132.

[0093] Specifically, the lower lid 12 is provided with an installation groove 123. In the radial direction of the container lid 1, one end of the second elastic member 15 is connected to the lower part of the locking key 132, and the other end is connected to the inner wall of the installation groove 123.

[0094] In a possible implementation manner, an elastic member is also provided between the locking key 132 and the limit key 131 to facilitate the rotation of the limit key 131 driving the locking key 132.

[0095] In a possible implementation manner, as Figure 2 and Figure 4As shown, the lower cover 12 is provided with a first rotating shaft 122. The locking key 132 is rotatably connected to the first rotating shaft 122, and the first elastic member 14 is sleeved on the first rotating shaft 122. The limiting key 131 has a chute (not shown in the figure) extending along the height direction of the container lid 1. The limiting key 131 is rotatably connected to the first rotating shaft 122 through the chute.

[0096] In this embodiment, the first elastic member 14 is sleeved on the first rotating shaft 122. The locking key 132 may be provided with a connection hole (not shown in the figure) so that the first rotating shaft 122 can be rotatably connected to the locking key 132 through the connection hole. The limiting key 131 is provided with a chute extending along the height direction of the container lid 1 so that the first rotating shaft 122 can be rotatably connected to the limiting key 131 through the chute, enabling the limiting key 131 and the locking key 132 to rotate relative to the lower cover 12. At the same time, the chute extends along the height direction of the container lid 1, enabling the limiting key 131 to not only rotate relative to the lower cover 12 but also move relative to the lower cover 12 along the height direction of the container lid 1, improving the feasibility of the limiting key 131 to switch between the locking position and the unlocking position.

[0097] Among them, the first rotating shaft 122 is installed in the installation groove 123 of the lower cover 12.

[0098] In a possible implementation manner, as Figure 6 shown, in the locking position, there is a gap 133 between the locking key 132 and the limiting key 131 along the radial direction of the container lid 1, enabling the locking key 132 to rotate relative to the limiting key 131 during the locking fit process of the first engaging portion 111 and the second engaging portion 121, causing the first elastic member 14 to elastically deform.

[0099] When the limiting key 131 moves to the locking position, during the process of the upper cover 11 covering the lower cover 12, as Figure 7As shown in the figure, along the radial direction of the container lid 1, the first engaging portion 111 connected to the upper lid 11 can press the second engaging portion 121. Since there is a gap 133 between the locking key 132 and the limiting key 131, the second engaging portion 121 rotates in a direction away from the first engaging portion 111. As a result, the locking key 132 rotates until its outer wall abuts against the inner wall of the limiting key 131. At this time, since the limiting key 131 abuts against the lower lid 12, that is, the limiting key 131 cannot rotate, the locking key 132 cannot continue to rotate under the limiting action of the limiting key 131. After the locking key 132 rotates, the radial distance between the second engaging portion 121 and the lower lid 12 increases, enabling the first engaging portion 111 to extend between the second engaging portion 121 and the lower lid 12. At the same time, under the resilience of the second elastic member 15, the first engaging portion 111 can be locked and engaged with the second engaging portion 121 in place. Therefore, due to the gap 133 between the locking key 132 and the limiting key 131 along the radial direction of the container lid 1, when the limiting key 131 is in the locked position, the first engaging portion 111 can be automatically locked and engaged with the second engaging portion 121 in place without the need for separate user operation, improving the convenience of closing the container lid 1.

[0100] In a possible implementation manner, as Figure 6 shown, along the radial direction of the container lid 1, the size of the gap 133 is L1, and the mating size when the first engaging portion 111 and the second engaging portion 121 are locked and engaged is L2, where L1 < L2.

[0101] In this embodiment, the size L1 of the gap 133 between the locking key and the limiting key 131 can be slightly smaller than the mating size L2 when the first engaging portion 111 and the second engaging portion 121 are locked and engaged, that is, the distance that the second engaging portion 121 can rotate is less than the size of the locking and engagement between the first engaging portion 111 and the second engaging portion 121. When the first engaging portion 111 and the second engaging portion 121 are locked and engaged, the first engaging portion 111 and the second engaging portion 121 can be mutually pressed in the radial direction, thereby further improving the stability and reliability of the locking and engagement between the first engaging portion 111 and the second engaging portion 121.

[0102] Among them, the mating size L2 when the first engaging portion 111 and the second engaging portion 121 are locked and engaged is: the size where the projections of the first engaging portion 111 and the second engaging portion 121 in the height direction coincide when they are in the locked and engaged state.

[0103] An embodiment of the present application provides a liquid container, as Figure 1 and Figure 4 shown, the liquid container includes a container body 2 and a container lid 1, and the container lid 1 is installed on the container body 2. Among them, the container lid 1 is the container lid 1 in any of the above embodiments.

[0104] In this embodiment, the container lid 1 is threadedly connected to the container body 2 through the lower lid 12. When the container lid 1 is used for the container body 2, the limit key 131 of the container lid 1 can automatically reset from the unlocking position to the locking position. After the user closes the upper lid 11, the upper lid 11 and the lower lid 12 are relatively fixed under the restriction of the limit key 131, so that the container lid 1 can be automatically locked, reducing the risk that the upper lid 11 is accidentally opened due to the user accidentally touching the button assembly 13, avoiding the risk of the liquid in the container body 2 flowing out, thereby reducing the risk of scalding the user or wetting the clothes, improving the use safety of the liquid container, and further improving the user experience of using the liquid container.

[0105] In a possible implementation manner, as Figure 4 shown, the lower lid 12 may include a drinking port 17, and the upper lid 11 may include an inner lid 112 and a first seal 18 installed on the inner lid 112. When the upper lid 11 is closed on the lower lid 12, the first seal 18 of the inner lid 112 is used to block the drinking port 17 to prevent the liquid from leaking from the drinking port 17. At the same time, a second seal 21 is provided at the opening of the container body 2, and the second seal 21 is connected to the drinking port 17 to enable the liquid to flow out through the drinking port 17 when the liquid container is pouring the liquid, so as to prevent the liquid from flowing out from other positions.

[0106] The above are only the specific implementation manners of the embodiments of the present application, but the protection scope of the embodiments of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of the present application should be covered by the protection scope of the embodiments of the present application. Therefore, the protection scope of the embodiments of the present application shall be subject to the protection scope of the claimed rights.
