Description

Technical Field

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

[0002] At present, the lids of portable water cups such as sports water cups generally include a first lid body and a second lid body, and usually a self-locking button for opening and closing the first lid body is configured. The self-locking button is convenient for single-handed operation and can reduce the risk of accidental opening of the first lid body. However, during the process of the first lid body being closed on the second lid body, it is often necessary to forcefully match the first lid body with the self-locking button to relatively fix the first lid body and the second lid body, which is prone to the risk of wear between the two, and reduces the user's feeling of closing the lid. Summary of the Utility Model

[0003] This application provides a container lid and a liquid container, which are used to solve the problem that during the process of the first lid body of a water cup provided with a self-locking button being closed on the second lid body, it is necessary to forcefully match the first lid body with the self-locking button to relatively fix the first lid body and the second lid body, which is prone to the risk of wear between the two, and reduces the user's feeling of closing the lid.

[0004] In the first aspect of this application, a container lid is provided. The container lid includes a first lid body, a second lid body, a blocking member and a locking assembly. The first lid body is rotatably connected to the second lid body. The blocking member is movably connected to the second lid body. The locking assembly is movably connected to the second lid body, and the locking assembly has at least a locking position and an unlocking position. Wherein, in the locking position, the locking assembly is used to limit the unlocking fit between the first lid body and the second lid body. In the unlocking position, the locking assembly releases the limitation on the unlocking fit between the first lid body and the second lid body. The blocking member abuts against the locking assembly to make the locking assembly tilt relative to the container lid in a direction away from the locking position.

[0005] In this solution, since in the unlocking position, the locking assembly tilts relative to the container lid in a direction away from the locking position under the action of the blocking member, during the process of the first lid body being buckled on the second lid body, that is, during the process of moving from the unlocking position to the locking position, there is a gap between the first lid body and the second lid body, reducing the risk of wear between the first lid body and the second lid body during the buckling process and improving the service life of the container lid. At the same time, since there is a gap between the first lid body and the second lid body during the buckling process, it is beneficial to improve the smoothness of the user buckling the first lid body, thereby improving the user's feeling of closing the lid and thus improving the use experience. In addition, in the unlocking position, the blocking member abuts against the locking assembly, and can also keep the locking assembly in the unlocking position.

[0006] In this solution, the first cover body is provided with a first mating part, and the locking assembly is provided with a second mating part for locking and mating with the first mating part. At the locking position, the locking assembly is used to restrict the unlocking of the first mating part and the second mating part. At the unlocking position, the locking assembly releases the restriction on the first mating part and the second mating part.

[0007] During the process of the locking assembly switching from the unlocking position to the locking position, the first mating part can drive the blocking part to move along the height direction of the container cover, so that the blocking part is disengaged from the locking assembly. During the process of the locking assembly switching from the unlocking position to the position where the first mating part abuts against the blocking part, the second mating part is located outside the movement track of the first mating part.

[0008] In this solution, the second mating part is located outside the movement track of the first mating part, that is, during the rotation of the first mating part with the first cover body, the movement tracks of the first mating part and the second mating part never coincide, so that the first mating part and the second mating part are not in contact during this process, reducing the risk of wear between the first mating part and the second mating part and improving the service life of the container cover.

[0009] In this solution, the container cover further includes a first elastic member. Along the height direction of the container cover, one end of the first elastic member is connected to the second cover body, and the other end is connected to the blocking part.

[0010] In this solution, by providing the first elastic member on the container cover, after the first mating part and the second mating part are unlocked, the blocking part can automatically move to the position where it abuts against the locking assembly, so that the first mating part cannot contact the second mating part during the buckling process of the first cover body, improving the buckling feel and thus enhancing the user experience.

[0011] In this solution, the blocking part includes a main body and a first abutting part. The first abutting part protrudes relative to the main body in the direction towards the locking assembly. At the unlocking position, the first abutting part abuts against the locking assembly. At the locking position, the first abutting part is disengaged from the locking assembly.

[0012] In this solution, at the unlocking position, under the action of the abutment of the first abutting part, the locking assembly is inclined relative to the container cover in a direction away from the locking position, so that the second mating part is located outside the movement track of the first mating part, improving the reliability that the first mating part does not contact the second mating part during the buckling process of the first cover body.

[0013] In this solution, a notch is provided on the top wall of the main body. At the locking position, a part of the first mating part is located in the notch and abuts against the main body.

[0014] In this solution, during the process from the unlocking position to the locking position, the first matching portion can abut against the body to drive the blocking member to move away from the first cover body in the direction of the height of the container cover, so that the second matching portion can be tilted relative to the container cover in the direction close to the locking position, and then the second matching portion can be rotated relative to the second cover body to lock the first matching portion with the second matching portion. At the same time, a part of the first matching portion is located in the notch, which is conducive to improving the reliability and stability of the first matching portion driving the blocking member to move in the height direction of the container cover.

[0015] In this embodiment, the blocking member also includes a first limiting portion connected to the main body, the second cover body is provided with a first mounting groove, the first mounting groove has a limiting retaining wall, the blocking member is movably installed in the first mounting groove, and the first limiting portion can abut against the limiting retaining wall to limit the blocking member from detaching from the first mounting groove.

[0016] In this solution, the blocking member is installed in the first installation groove, and the first limiting portion can abut against the limiting blocking wall along the height direction of the container cover to limit the blocking member from detaching from the first installation groove along the height direction of the container cover under the action of the rebound force of the first elastic member, thereby improving the reliability and stability of the connection between the blocking member and the second cover body.

[0017] In this solution, the first limiting portion is at least two hooks connected to the main body, and a connecting rod for sleeve-connecting the first elastic member is provided between the at least two hooks.

[0018] In this solution, the first elastic member is connected to the blocking member via a connecting rod, which is conducive to improving the reliability and stability of the connection between the first elastic member and the blocking member. At the same time, the first limit portion is a hook structure, which is conducive to increasing the contact area between the first limit portion and the limit blocking wall, thereby improving the stability of the contact between the first limit portion and the limit blocking wall.

[0019] In this solution, the locking assembly further includes a limit key and a locking key, the limit key can move relative to the second cover body so that the locking assembly is in a locked position or an unlocked position, the limit key is used to limit the first matching portion and the second matching portion from releasing the locking match, in the unlocked position, the limit key releases the restriction on the first matching portion and the second matching portion, the limit key is located on the outside of the locking key, the second matching portion is arranged on the locking key, and the locking key is rotatably connected to the second cover body. The locking key includes a second limit portion, in the unlocked position, the second limit portion abuts against the first abutting portion of the blocking member, and in the locked position, the second limit portion abuts against the body of the blocking member.

[0020] In this solution, the first cover body and the second cover body maintain a mutually locked state under the restriction of the limit key, reducing the risk that the first cover body is accidentally opened due to the user accidentally touching the locking component, reducing the risk of scalding or wetting clothes, improving the use safety of the container cover, and further improving the user experience.

[0021] In addition, at the unlocking position, the second limiting portion is used to abut against the first abutting portion, and the second limiting portion protrudes towards the blocking member relative to the second matching portion, so as to improve the reliability and stability of the abutment between the blocking member and the locking component.

[0022] In this solution, the container cover further includes a torsion spring. The second cover body is provided with a first rotating shaft, the locking key is rotatably connected to the first rotating shaft, and the torsion spring 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. The torsion spring is used to drive the locking component to return to the locking position, and / or the container cover further includes a second elastic member. Along the radial direction of the container cover, the second elastic member is elastically connected to the locking key and the second cover body.

[0023] In this solution, along the height direction of the container cover, the limit key has a stepped portion, and the torsion spring has an extension section, and the extension section is connected to the stepped portion. When the limit key is switched from the locking position to the unlocking position under the action of an external force, the limit key drives the extension section of the torsion spring to move through the stepped portion, so that the torsion spring member is compressed. When the external force is cancelled, under the action of the resilience of the torsion spring, the limit key is driven to move to the locking position through the extension section, so as to lock the container cover. Therefore, the container cover can be automatically locked through the torsion spring without manual operation by the user, improving the convenience of user use.

[0024] In this solution, the container cover further includes a second elastic member. Along the radial direction of the container cover, the second elastic member is elastically connected to the locking key and the second cover body.

[0025] In this solution, through the second elastic member connected between the second cover body and the locking key, the locking key and the limit key can automatically rotate relative to the second cover body, so that the second matching portion can automatically reset to the position where it is locked and matched with the first matching portion, so that during the process of closing the first cover body, it is convenient for the first matching portion and the second matching portion to be locked and matched, so that the container cover can be automatically locked without manual locking by the user. Therefore, the second elastic member can promote the limit key to automatically return to the locking position, further preventing the first cover body from being accidentally opened due to the inability of the limit key to lock the locking key.

[0026] In the second aspect of the present application, a liquid container is provided. The liquid container includes a container body and a container cover, and the container cover is installed on the container body. Among them, the container cover is the container cover described above.

[0027] In this solution, the container lid is threadedly connected to the container body through the second lid body. When the container lid is used for the container body, during the process of the first lid body being buckled onto the second lid body, the blocking member causes a gap between the first engaging portion and the second engaging portion, so that the first engaging portion and the second engaging portion cannot come into contact under the action of the blocking member during the buckling process, reducing the risk of wear of the first engaging portion and the second engaging portion due to abutment during the buckling process, improving the service life and usage experience of the container lid, and thus improving the service life and usage experience of the liquid container body.

[0075] 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.

[0076] In a specific embodiment, the present application will be further described in detail below through specific embodiments and with reference to the accompanying drawings.

[0077] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

The singular forms "a", "the", and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0079] It should be understood that the term " / and / " used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the preceding and following associated objects.

[0080] 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 drawings and should not be construed as limitations on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0081] An embodiment of the present application provides a container lid 1, as Figures 1-3 shown. The container lid 1 includes a first lid body 11, a second lid body 12, a locking assembly 13, and a blocking member 17. The first lid body 11 is rotatably connected to the second lid body 12, and the blocking member 17 is movably connected to the second lid body 12. The locking assembly 13 is movably connected to the second lid body 12, and the locking assembly 13 has at least a locking position and an unlocking position.

[0082] Wherein, in the locking position, the locking assembly 13 is used to restrict the first lid body 11 and the second lid body 12 from releasing the locking fit. In the unlocking position, the locking assembly 13 releases the restriction on the locking fit between the first lid body 11 and the second lid body 12. The blocking member 17 abuts against the locking assembly 13, so that the locking assembly 13 tilts relative to the container lid 1 in a direction away from the locking position.

[0083] Therefore, since in the unlocking position the locking assembly 13 tilts relative to the container lid 1 in a direction away from the locking position under the action of the blocking member 17, that is, the locking assembly 13 tilts outward relative to the container lid 1, as Figure 3 and Figure 6 shown, during the process of the first lid body 11 being buckled onto the second lid body 12, that is, during the process of moving from the unlocking position to the locking position, there is a gap between the locking structures of the first lid body 11 and the second lid body 12, reducing the risk of wear between the first lid body 11 and the second lid body 12 during the buckling process and improving the service life of the container lid 1. At the same time, since there is a gap between the locking structures of the first lid body 11 and the second lid body 12 during the buckling process, it is beneficial to improve the smoothness of the user buckling the first lid body 11, thereby improving the user's feeling of closing the lid and thus improving the use experience. In addition, in the unlocking position, the blocking member 17 abuts against the locking assembly 13, and can also keep the locking assembly 13 in the unlocking position.

[0084] In a possible implementation manner, as Figures 2-4 shown, the first lid body 11 is provided with a first engaging portion 111, and the locking assembly 13 is provided with a second engaging portion 121 for locking and cooperating with the first engaging portion 111. In the locking position, the locking assembly 13 is used to restrict the first engaging portion 111 and the second engaging portion 121 from releasing the locking fit. In the unlocking position, the locking assembly 13 releases the restriction on the first engaging portion 111 and the second engaging portion 121.

[0085] During the process of the first cover 11 being opened relative to the second cover 12, that is, when moving from the locked position as shown in Figure 4 to the unlocked position as shown in Figure 2 the blocking member 17 can move relative to the second cover 12 so that the blocking member 17 can abut against the locking assembly 13, thereby causing the locking assembly 13 to tilt relative to the container lid 1 in a direction away from the locked position, that is, along the radial direction of the container lid 1. The second mating portion 121 in the locking assembly 13 at the unlocked position is farther from the center of the container lid 1 than the second mating portion 121 in the locking assembly 13 at the locked position, so that the second mating portion 121 at the unlocked position has an included angle with respect to the height direction of the container lid 1.

[0086] During the process of the first cover 11 being fastened to the second cover 12, that is, when moving from the unlocked position as shown in Figure 2 to the locked position as shown in Figure 4 the blocking member 17 moves relative to the second cover 12. When the first cover 11 moves to the position where it is fastened to the second cover 12, the blocking member 17 moves to a position where it disengages from abutting against the locking assembly 13 and disengages from abutting against the locking assembly 13. Furthermore, the locking assembly 13 rotates relative to the second cover 12 so that the second mating portion 121 at the unlocked position has no included angle or the included angle decreases with respect to the height direction of the container lid 1, thereby enabling the first mating portion 111 and the second mating portion 121 to be in locking fit.

[0087] Therefore, since the locking assembly 13 is tilted relative to the container lid 1 in a direction away from the locked position under the action of the blocking member 17 at the unlocked position, as shown in Figure 3 and Figure 6 during the process of the first cover 11 being fastened to the second cover 12, that is, during the process of moving from the unlocked position to the locked position, a gap is formed between the first mating portion 111 and the second mating portion 121, so that the first mating portion 111 and the second mating portion 121 cannot come into contact during the fastening process (or there is contact but the friction force between them is very small. In this article, the case where the first mating portion 111 and the second mating portion 121 have no contact is taken as an example for description), reducing the risk of wear of the first mating portion 111 and the second mating portion 121 due to abutment during the fastening process and improving the service life of the container lid 1. At the same time, since the first mating portion 111 and the second mating portion 121 have no contact during the fastening process, it is beneficial to improve the smoothness of the user fastening the first cover 11, thereby improving the user's feeling of closing the lid and thus improving the use experience. In addition, at the unlocked position, the blocking member 17 abuts against the locking assembly 13, and can also keep the locking assembly 13 in the unlocked position.

[0088] Specifically, during the process of the locking assembly 13 switching from the unlocked position to the locked position, the first engaging portion 111 can drive the blocking member 17 to move in the height direction of the container lid 1, so that the blocking member 17 is disengaged from the locking assembly 13. In other embodiments, the first engaging portion 111 can also drive the blocking member 17 to rotate relative to the second lid body 12, so that the blocking member 17 is disengaged from the locking assembly 13. That is to say, the blocking member 17 can be slidably connected or rotatably connected to the second lid body 12.

[0089] During the process of the locking assembly 13 switching from the unlocked position to the state where the first engaging portion 111 abuts against the blocking member 17, the second engaging portion 121 is located outside the movement track of the first engaging portion 111. Among them, the movement track of the first engaging portion 111 is an arc centered on the second rotating shaft 19 (such as Figure 2 the arc dotted line).

[0090] In this embodiment, it can be seen from Figure 2 that the second engaging portion 121 is located outside the movement track of the first engaging portion 111, that is, during the rotation of the first engaging portion 111 with the first lid body 11 (that is, from Figure 2 the state shown to Figure 3 the state shown), the movement tracks of the first engaging portion 111 and the second engaging portion 121 do not coincide all the time, so that the first engaging portion 111 and the second engaging portion 121 are not in contact during this process, reducing the risk of wear between the first engaging portion 111 and the second engaging portion 121 and improving the service life of the container lid 1. When the first lid body 11 moves to the position shown in Figure 3 , the first engaging portion 111 abuts against the blocking member 17, so that the blocking member 17 is driven by the first engaging portion 111 to move away from the first engaging portion 111 in the height direction of the container lid 1, so that the blocking member 17 is disengaged from the locking assembly 13, and the first engaging portion 111 and the second engaging portion 121 can be locked and engaged.

[0091] In a possible implementation manner, as shown in Figure 7 , the first engaging portion 111 can be snap-fitted with the second engaging portion 121. When the first engaging portion 111 is snap-fitted with the second engaging portion 121, the first lid body 11 and the second lid body 12 are snap-fitted through the locking assembly 13 to limit the opening of the first lid body 11. Therefore, the snap-fitting method is beneficial to improving the reliability of the locking engagement between the first engaging portion 111 and the second engaging portion 121, thereby improving the reliability and stability of the first lid body 11 maintaining the state of being buckled on the second lid body 12.

[0092] In a possible implementation manner, as shown in Figure 5 , Figure 6 and Figure 11As shown, the blocking member 17 includes a main body 171 and a first abutting portion 172. The first abutting portion 172 protrudes relative to the main body 171 in the direction towards the locking assembly 13. In the unlocking position, the first abutting portion 172 abuts against the locking assembly 13, and in the locking position, the first abutting portion 172 is disengaged from abutting against the locking assembly 13.

[0093] In this embodiment, in the unlocking position, under the action of the abutment of the first abutting portion 172, the locking assembly 13 is inclined relative to the container lid 1 in a direction away from the locking position, so that the second engaging portion 121 is located outside the movement track of the first engaging portion 111, improving the reliability that the first engaging portion 111 does not contact the second engaging portion 121 during the buckling process of the first lid body 11.

[0094] In a possible implementation manner, as Figure 4 、 Figure 7 and Figure 11 shown, in the locking position, the main body 171 abuts against the locking assembly 13.

[0095] In this embodiment, the main body 171 is provided with an avoidance portion 175, and the first abutting portion 172 is located outside the avoidance portion 175, that is, the first abutting portion 172 protrudes relative to the avoidance portion 175 in the direction towards the locking assembly 13. After the locking assembly 13 is disengaged from abutting against the first abutting portion 172, the locking assembly 13 can rotate relative to the second lid body 12, so that the second engaging portion 121 abuts against the avoidance portion 175, reducing the risk of the second engaging portion 121 rotating inwardly towards the blocking member 17, thereby reducing the risk of overfitting between the first engaging portion 111 and the second engaging portion 121, and thus reducing the risk of damage to the first engaging portion 111 and the second engaging portion 121.

[0096] In a possible implementation manner, as Figure 7 and Figure 11 shown, the top wall of the main body 171 is provided with a notch 171a. In the locking position, a part of the first engaging portion 111 is located in the notch 171a and abuts against the main body 171.

[0097] In this embodiment, during the process from the unlocking position to the locking position, the first engaging portion 111 can abut against the main body 171 to drive the blocking member 17 to move away from the first lid body 11 along the height direction of the container lid 1, so that the second engaging portion 121 can be inclined relative to the container lid 1 in a direction towards the locking position. Furthermore, the second engaging portion 121 can rotate relative to the second lid body 12, so that the first engaging portion 111 and the second engaging portion 121 are in locking fit. At the same time, a part of the first engaging portion 111 is located in the notch 171a, which is beneficial to improving the reliability and stability of the first engaging portion 111 driving the blocking member 17 to move along the height direction of the container lid 1.

[0098] In a possible implementation, as Figure 7 and Figure 11 shown, the blocking member 17 further includes a connecting rod 173 connected to the body 171, and the container lid 1 further includes a first elastic member 18. Along the height direction of the container lid 1, one end of the first elastic member 18 is connected to the second lid body 12, and the other end is sleeved on the connecting rod 173.

[0099] In this embodiment, during the process of the first lid body 11 being buckled, the first engaging portion 111 can drive the blocking member 17 to move away from the first lid body 11 along the height direction of the container lid 1, so that the first elastic member 18 is compressed. During the process of the first lid body 11 being opened, the blocking member 17 can move towards the first lid body 11 along the height direction of the container lid 1 under the action of the resilience of the first elastic member 18, so that the first abutting portion 172 of the blocking member 17 abuts against the locking assembly 13, thereby causing the locking assembly 13 at the unlocking position to tilt relative to the container lid 1 in a direction away from the locking position.

[0100] Therefore, by providing the first elastic member 18 on the container lid 1, after the first engaging portion 111 and the second engaging portion 121 are disengaged from the locking engagement, the blocking member 17 can automatically move to the position where it abuts against the locking assembly 13, so that the first engaging portion 111 cannot contact the second engaging portion 121 during the process of the first lid body 11 being buckled, improving the buckling feel and further improving the user experience.

[0101] In a possible implementation, as Figures 9-11 shown, the blocking member 17 further includes a first limiting portion 174 connected to the body 171. The second lid body 12 is provided with a first installation groove 125, and the first installation groove 125 has a limiting stop wall 125a. The blocking member 17 is movably installed in the first installation groove 125, and the first limiting portion 174 can abut against the limiting stop wall 125a to limit the blocking member 17 from disengaging from the first installation groove 125.

[0102] In this embodiment, the blocking member 17 is installed in the first installation groove 125, and the first limiting portion 174 can abut against the limiting stop wall 125a along the height direction of the container lid 1 to limit the blocking member 17 from disengaging from the first installation groove 125 under the action of the resilience of the first elastic member 18, improving the reliability and stability of the connection between the blocking member 17 and the second lid body 12.

[0103] In a possible implementation, as Figures 9-11 shown, the first limiting portion 174 is at least two hooks connected to the body 171, and a connecting rod 173 for sleeving the first elastic member 18 is provided between the at least two hooks.

[0104] In this embodiment, the first elastic member 18 is connected to the blocking member 17 via the connecting rod 173, which is beneficial to improving the reliability and stability of the connection between the first elastic member 18 and the blocking member 17. At the same time, the first limiting portion 174 is a hook structure, which is beneficial to increasing the contact area between the first limiting portion 174 and the limiting wall 125a, thereby improving the stability of the contact between the first limiting portion 174 and the limiting wall 125a.

[0105] In a possible implementation manner, as Figure 6 and Figure 7 shown, the locking assembly 13 further includes a limit key 131, and the limit key 131 can move relative to the second cover 12 to make the locking assembly 13 in a locked position or an unlocked position. Specifically, when the user needs to open the first cover 11, the limit key 131 is driven from Figure 4 the locked position to the unlocked position as shown in Figure 2 . When the limit key 131 is in the unlocked position, the first engaging portion 111 and the second engaging portion 121 can be disengaged from the locking engagement, thereby releasing the restriction on the relative rotation of the first cover 11 and the second cover 12, and the first cover 11 can rotate relative to the second cover 12 to make the container lid 1 in an open state.

[0106] When the user needs to close and lock the first cover 11, the external force applied to the limit key 131 is cancelled and the first cover 11 is driven to rotate towards the second cover 12, so that the blocking member 17 can move relative to the second cover 12, so that the blocking member 17 is disengaged from the locking assembly 13, so that the first engaging portion 111 can automatically lock with the second engaging portion 121 under the action of the locking assembly 13, thereby restricting the relative rotation of the first cover 11 relative to the second cover 12 to make the container lid 1 in a closed state.

[0107] Therefore, after the user closes the first cover 11, the first cover 11 and the second cover 12 maintain a mutually locked state under the restriction of the limit key 131, reducing the risk that the first cover 11 is accidentally opened due to the user accidentally touching the locking assembly 13, reducing the risk of scalding or wetting clothes, improving the use safety of the container lid 1, and further improving the user experience.

[0108] In a possible implementation manner, as Figure 2 shown, the side of the container lid 1 facing away from the locking assembly 13 may include a second rotating shaft 19, and the first cover 11 and the second cover 12 are rotatably connected through the second rotating shaft 19. A third elastic member may be provided on the second rotating shaft 19. When the first engaging portion 111 and the second engaging portion 121 are disengaged from the locking engagement, the third elastic member causes the first cover 11 to automatically rotate upward, so that the container lid 1 can be automatically opened.

[0109] In a possible implementation manner, as Figure 5As shown, the locking assembly 13 further includes a locking key 132. The limiting key 131 is located outside the locking key 132. The second engaging portion 121 is provided on the locking key 132. The locking key 132 is rotatably connected to the second cover 12. The locking key 132 includes a second limiting portion 132a. In the unlocking position, the second limiting portion 132a abuts against the first abutting portion 172 of the blocking member 17. In the locking position, the second limiting portion 132a abuts against the body 171 of the blocking member 17.

[0110] In this embodiment, in the unlocking position, the second limiting portion 132a is used to abut against the first abutting portion 172. The second limiting portion 132a protrudes towards the blocking member 17 relative to the second engaging portion 121 to improve the reliability and stability of the abutment between the blocking member 17 and the locking assembly 13. In the locking position, the second limiting portion 132a is used to abut against the above-mentioned avoiding portion 175 so that the first engaging portion 111 can be in locking engagement with the second engaging portion 121.

[0111] In addition, during the movement of the limiting key 131 between the locking position and the unlocking position, by rotating the limiting key 131 relative to the second cover 12, the locking key 132 located inside is driven to rotate accordingly. As a result, the second engaging portion 121 on the locking key 132 can be in locking engagement or disengaged from the first engaging portion 111, which is beneficial to improving the reliability of driving the movement of the second engaging portion 121 and the reliability of switching between the opened and closed states of the container lid 1. Therefore, in this embodiment, the locking key 132 of the locking assembly 13 is used to cooperate with or disengage from the first cover 11. When the limiting key 131 is in the locking position, the locking key 132 cannot rotate, and the locking key 132 is restricted to the state of cooperating with the first cover 11 by the limiting key 131 to prevent the first cover 11 from being accidentally opened. When the limiting key 131 is in the unlocking position, the locking key 132 cannot rotate towards the blocking member 17 under the action of the abutment of the blocking member 17, so that the second engaging portion 121 of the locking key 132 inclines away from the locking position relative to the container lid 1, that is, the second engaging portion 121 of the locking key 132 inclines outwards relative to the container lid 1.

[0112] In a possible implementation manner, as Figure 4 、 Figure 6 and Figure 7 shown, the container lid 1 further includes a torsion spring 14. The second 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 torsion spring 14 is sleeved on the first rotating shaft 122. The limiting key 131 has a chute 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. The torsion spring 14 is used to drive the locking assembly 13 to return to the locking position. Among them, the torsion spring 14 can be installed on the second cover 12 and connected to the locking assembly 13.

[0113] In this embodiment, along the height direction of the container lid 1, the limiting key 131 has a stepped portion 131a, and the torsion spring 14 has an extension section 141, and the extension section 141 is connected to the stepped portion 131a. When the limiting key 131 is switched from the locking position to the unlocking position under the action of an external force, the limiting key 131 drives the extension section 141 of the torsion spring 14 to move through the stepped portion 131a, so that the torsion spring 14 is compressed. When the external force is cancelled, under the action of the resilience of the torsion spring 14, the limiting key 131 is driven by the extension section 141 to move to the locking position, so as to lock the container lid 1. Therefore, the container lid 1 can be automatically locked through the torsion spring 14 without manual operation by the user, improving the convenience of user use.

[0114] Wherein, the stepped portion 131a and the extension section 141 can be connected by means of bonding, welding, abutting, etc., and the application does not limit the connection manner of the stepped portion 131a and the extension section 141.

[0115] Specifically, the limiting key 131 can rotate relative to the second lid body 12 and can move along the height direction of the container lid 1 relative to the second lid body 12, so that the limiting key 131 is in the locking position or the unlocking position. In the locking position, the limiting key 131 abuts against the second lid body 12 to limit the rotation of the limiting key 131 and to limit the unlocking fit between the first engaging portion 111 and the second engaging portion 121. In the unlocking position, the limiting key 131 is disengaged from abutting against the second lid body 12, so that the limiting key 131 can rotate, enabling the first engaging portion 111 and the second engaging portion 121 to be disengaged from the locking fit.

[0116] When the limiting key 131 needs to move from the locking position to the unlocking position, along the height direction of the container lid 1, the user needs to push the limiting key 131 downward so that the limiting key 131 moves downward and is disengaged from abutting against the second lid body 12. Then, the user can press the limiting key 131 toward the second lid body 12 so that the limiting key 131 can rotate. At this time, the limiting key 131 is in the unlocking position, enabling the first engaging portion 111 and the second engaging portion 121 to be disengaged from the locking fit.

[0117] When the limiting key 131 needs to move from the unlocking position to the locking position, the external force applied to the limiting key 131 is cancelled. Then, the limiting key 131 can rotate and move upward along the height direction of the container lid 1 under the action of the resilience of the torsion spring 14, that is, the limiting key 131 can return to the position where the limiting key 131 abuts against the second lid body 12 under the action of the resilience of the torsion spring 14, thereby restricting the rotation of the limiting key 131, and thus restricting the unlocking fit between the first engaging portion 111 and the second engaging portion 121, so that the first lid body 11 and the locking assembly 13 are maintained in a mating state, reducing the risk of accidental opening of the first lid body 11.

[0118] Specifically, in a possible implementation manner, such asFigure 5 and Figure 7 As shown, the second cover body 12 has a blocking portion 123a extending in the direction of the limit key 131, and the limit key 131 has a second abutting portion 131b extending in the direction of the second cover body 12. In the locked position, the second abutting portion 131b abuts against the blocking portion 123a, and in the unlocked position, the second abutting portion 131b is located on the side of the blocking portion 123a that is away from the first cover body 11.

[0119] In this embodiment, when the limit key 131 is in the locked position, the second abutting portion 131b abuts against the blocking portion 123a to limit the rotation of the limit key 131 relative to the second cover body 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, thereby improving the reliability and stability of the container cover 1 in the snap-fit state. The second abutting portion 131b and the blocking portion 123a can facilitate the abutment of the limit key 131 with the second cover body 12, thereby facilitating the limit key 131 to be in the locked position.

[0120] In a possible implementation, Figure 7 As shown, the container cover 1 further includes 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 second cover body 12 .

[0121] When the limit key 131 needs to move to the unlocking position, the limit key 131 is pushed downward to make the limit key 131 move downward along the height direction of the container cover 1, so that the torsion spring 14 is compressed, and then the locking assembly 13 is released from the abutment with the second cover body 12, and then the lower part of the limit key 131 is pressed along the radial direction of the container cover 1 toward the second cover body 12, and then the limit key 131 drives the locking key 132 to rotate together toward the direction of the second cover body 12, and the second elastic member 15 is compressed to make the second matching portion 121 rotate away from the first matching portion 111, so that the first matching portion 111 and the second matching portion 121 are released from the locking match.

[0122] When the limit key 131 needs to move to the locked position, during the process of canceling the external force applied to the limit key 131 and fastening the first cover body 11, along the radial direction of the container cover 1, the blocking member 17 moves downward along the height direction of the container cover 1 under the action of the abutment of the first cover body 11, and then the limit key 131 and the locking key 132 can rotate together toward the direction of the blocking member 17 under the action of the rebound force of the second elastic member 15, and at the same time, the limit key 131 can automatically move upward to the locked position under the action of the rebound force of the torsion spring 14, and then the blocking portion 123a abuts against the second abutting portion 131b, and the second matching portion 121 rotates toward the first matching portion 111, so that the second matching portion 121 moves to a position where it is locked and matched with the first matching portion 111.

[0123] Through a second elastic member 15 connected between the second cover body 12 and the locking key 132, the locking key 132 and the limiting key 131 can automatically rotate relative to the second cover body 12, so that the second engaging portion 121 can automatically reset to the position where it is locked and engaged with the first engaging portion 111. During the process of closing the first cover body 11, it is convenient for the first engaging portion 111 and the second engaging portion 121 to be locked and engaged, so that the container lid 1 can be automatically locked without manual locking by the user. Therefore, the second elastic member 15 can promote the automatic return of the limiting key 131 to the locking position, further preventing the first cover body 11 from being accidentally opened due to the inability of the limiting key 131 to lock the locking key 132.

[0124] Specifically, as Figure 8 shown, the second cover body 12 is provided with a second installation groove 123. Along 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 second installation groove 123.

[0125] The embodiment of the present application also provides a liquid container. As Figure 1 and Figure 3 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.

[0126] In this embodiment, the container lid 1 is threadedly connected to the container body 2 through the second cover body 12. When the container lid 1 is used for the container body 2, during the process of the first cover body 11 being buckled onto the second cover body 12, the blocking member 17 makes a gap between the first engaging portion 111 and the second engaging portion 121. Thus, during the buckling process, the first engaging portion 111 and the second engaging portion 121 cannot contact under the action of the blocking member 17, reducing the risk of wear due to abutment between the first engaging portion 111 and the second engaging portion 121 during the buckling process, improving the service life and usage experience of the container lid 1, and thus improving the service life and usage experience of the liquid container body 2.

[0127] In a possible implementation manner, as Figure 4 shown, the second cover body 12 may include a drinking port 124, and the first cover body 11 may include an inner lid 112 and a first sealing member 113 installed on the inner lid 112. When the first cover body 11 is buckled on the second cover body 12, the first sealing member 113 of the inner lid 112 is used to block the drinking port 124 to prevent liquid from leaking from the drinking port 124. At the same time, a second sealing member 21 is provided at the opening of the container body 2, and the second sealing member 21 is connected to the drinking port 124. When the liquid container is pouring liquid, the liquid can flow out through the drinking port 124 to prevent the liquid from flowing out from other positions.

[0128] The above are only specific embodiments 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 within 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 claims described above.
