Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid containers, in particular to a container cover and a liquid container. BACKGROUND

[0002] The liquid container comprises a detachably connected container cover and container body, and the container cover and the container body are usually connected by threads. The container cover and the container body are sealed by screwing. However, when using or cleaning, the container cover needs to be opened or screwed by two hands, which affects the convenience of use. SUMMARY

[0003] Therefore, the present application provides a container cover and a liquid container to solve the problem of poor convenience of use of the container cover in the prior art.

[0004] In a first aspect, the present application provides a container cover, which comprises: a cover body having a receiving cavity; a rotating member, a part of the structure of the rotating member extending out of the cover body and being capable of rotating relative to the cover body; a movable member located in the receiving cavity, the movable member being movably connected with the rotating member; wherein the rotating member is capable of driving the movable member to move away from the center of the container cover along the radial direction of the container cover during rotation of the rotating member, so that the movable member is located at a first position, or driving the movable member to move towards the center of the container cover along the radial direction of the container cover, so that the movable member is located at a second position; in the first position, the movable member can be locked with the container body, and in the second position, the movable member can be unlocked with the container body.

[0005] In this embodiment, the user moves the movable member away from or towards the container body by rotating the rotating member, that is, the rotation of the rotating member is switched to the radial movement of the movable member, so that the connection and separation of the container cover and the container body can be realized. No thread structure is arranged between the container cover and the container body. Compared with the process of connecting or separating the container cover and the container body by rotating the thread structure by more than 360°, when the rotation of the rotating member is switched to the radial movement of the movable member, the angle of rotation of the rotating member is less than 360°. The container cover in this embodiment has the advantages of being convenient and fast, and is easy to use, which improves the user's experience. At the same time, a part of the structure of the rotating member extends out of the cover body, which is convenient for the user to directly contact and rotate the rotating member with his hand.

[0006] In a specific embodiment, the rotating member is provided with a sliding groove, the movable member comprises a body and a sliding portion and a first engaging portion provided on the body, the sliding portion is in sliding engagement with the sliding groove; during rotation of the rotating member, the sliding portion is driven to slide along the sliding groove, so as to drive the movable member to move away from or towards the center of the container cover in the radial direction of the container cover, so as to make the movable member be in the first position or the second position; in the first position, the first engaging portion is capable of engaging with the container body, in the second position, the first engaging portion is capable of disengaging from the container body.

[0007] In the embodiment, when the rotating member is rotated in the first direction, the sliding groove provided on the rotating member is in sliding engagement with the sliding portion provided on the movable member, so as to drive the movable member to move in a direction away from the center of the container cover, so as to make the movable member be in the first position, i.e. the first engaging portion of the movable member is close to the side wall of the container body, so as to make the first engaging portion be capable of engaging with the container body, thereby realizing the engagement between the container cover and the container body. When the rotating member is rotated in the second direction, the sliding groove provided on the rotating member is in sliding engagement with the sliding portion provided on the movable member, so as to drive the movable member to move in a direction towards the center of the container cover, so as to make the movable member be in the second position, i.e. the first engaging portion of the movable member is away from the side wall of the container body, so as to make the first engaging portion be capable of disengaging from the container body, thereby realizing the disengagement between the container cover and the container body.

[0008] In a specific embodiment, along the extension direction of the sliding groove, the sliding groove has a first engaging position and a second engaging position, the distance between the first engaging position and the rotation center of the rotating member is L1, the distance between the second engaging position and the rotation center of the rotating member is L2, L1>L2; when the sliding portion is located at the first engaging position, the movable member is in the first position, when the sliding portion is located at the second engaging position, the movable member is in the second position.

[0009] In the embodiment, when the sliding part slides from the second matching position to the first matching position, the distance between the sliding part in the first matching position and the rotation center of the rotating part 111 is large, so that the distance between the first matching part connected with the sliding part and the rotation center of the rotating part is large, at this time, the movable part is in the first position, and the distance between the first matching part and the inner wall of the container body is small, so that the first matching part can match with the second matching part, so that the container cover and the container body are in the connected state. When the sliding part slides from the first matching position to the second matching position, the distance between the sliding part in the second matching position and the rotation center of the rotating part is small, so that the distance between the first matching part connected with the sliding part and the rotation center of the rotating part is small, at this time, the movable part is in the second position, and the distance between the first matching part and the inner wall of the container body is large, so that the first matching part can be matched with the second matching part, so that the container cover and the container body are in the separated state.

[0010] In a specific embodiment, the sliding groove is a circular arc, and the center of the circular arc is offset from the rotation center of the rotating part.

[0011] In the embodiment, the sliding groove is a circular arc, which facilitates the sliding of the sliding part relative to the sliding groove, so that the rotating part can be rotated without exerting a large force, and the use experience of the user is improved. The center of the circular arc is offset from the rotation center of the rotating part, so that the sliding groove has a first matching position and a second matching position, so that when the sliding part slides relative to the sliding groove, the movable part can be driven to be in the first position or the second position, and the state of the container cover is switched.

[0012] In a specific embodiment, the central angle of the sliding groove is 15°-90°.

[0013] In the embodiment, the central angle of the sliding groove should not be too large or too small. When it is too large, the angle to be turned when the sliding part switches between the first matching position and the second matching position is too large, so that the user needs to turn the rotating part by a large angle, which affects the convenience of use. When it is too small, the difference between the distance L1 between the first matching position and the rotation center of the rotating part and the distance L2 between the second matching position and the rotation center of the rotating part is small, so that the movable part moves a small distance along the radial direction of the container cover, and it is not easy to switch the matching relationship between the first matching part and the second matching part. Therefore, when the central angle of the sliding groove is in the range of 15°-90°, it is convenient to switch the matching relationship between the first matching part and the second matching part, and the rotating part 111 does not need to be turned by a large angle, which improves the convenience of use.

[0014] In a specific embodiment, the first matching position and the second matching position are located at two ends of the sliding groove along the extension direction thereof.

[0015] In the embodiment, the first and second engagement positions are located at two ends of the sliding groove along the extending direction of the sliding groove. When the container cover is in the first state by rotating the rotating member in the first direction, the sliding part abuts against the sidewall of the first engagement position, so that the rotating member cannot continue to rotate in the first direction. When the container cover is in the second state by rotating the rotating member in the second direction, the sliding part abuts against the sidewall of the second engagement position, so that the rotating member cannot continue to rotate in the second direction. Therefore, the first and second engagement positions are located at two ends of the sliding groove along the extending direction of the sliding groove, which facilitates the user to determine whether the rotation of the rotating member is in place to switch the state of the container cover.

[0016] In a specific embodiment, the container cover comprises two movable members arranged opposite along the radial direction of the container cover, and the rotating member comprises two sliding grooves. When the movable member is in the first position, the two sliding parts are located at the first engagement positions of the two sliding grooves, respectively. When the movable member is in the second position, the two sliding parts are located at the second engagement positions of the two sliding grooves, respectively.

[0017] In the embodiment, by arranging two movable members and sliding grooves opposite along the radial direction, when the container cover is connected with the container body, the first engagement part of each movable member can be engaged with the second engagement part, so as to improve the connection reliability and stability of the first and second engagement parts, thereby improving the connection reliability and stability of the container cover and the container body, and avoiding the phenomenon that the container cover or the container body falls off during use. Meanwhile, along the radial direction of the container cover, the first engagement positions of the two sliding grooves are away from each other, and the second engagement positions of the two sliding grooves are close to each other. Moreover, the two sliding parts are located at the same end of the two corresponding sliding grooves, i.e., the two sliding parts are located at the first engagement positions or the second engagement positions at the same time, so that the rotating member can rotate normally, and the interference between the sliding groove and the sliding part during rotation of the rotating member is avoided.

[0018] In a specific embodiment, a groove is arranged between the two sliding grooves.

[0019] In the embodiment, a groove is arranged between the adjacent sliding grooves, which can reduce the weight of the rotating member, thereby reducing the overall weight of the container cover, facilitating the user to hold or place the container cover, and improving the user's experience.

[0020] In a specific embodiment, the cover body is provided with a limiting part, the body is provided with a limiting engagement part, and the limiting part and the limiting engagement part are engaged to limit the rotation of the movable member.

[0021] In this embodiment, by setting a limiting part and a limiting mating part, the rotation of the movable part can be restricted. That is, when the rotating part rotates and the sliding part slides along the sliding groove, the limiting part and the limiting mating part cooperate to restrict the movable part from rotating under the drive of the sliding part, and only move radially along the container lid, thereby changing the position of the movable part to change the cooperation state between the first mating part and the second mating part.

[0022] In one specific embodiment, the limiting part is a limiting protrusion provided on the cover, and the limiting mating part is a limiting hole.

[0023] In this embodiment, the limiting part is a limiting protrusion provided on the lid, and the limiting mating part is a limiting hole, which facilitates the snap-fit ​​between the limiting part and the limiting mating part, and can improve the connection reliability between the limiting part and the limiting mating part. It avoids the phenomenon that the limiting part and the limiting mating part are not firmly snapped together during rotation, which would affect the normal use of the container lid. Moreover, making the limiting part a limiting protrusion and the limiting mating part a limiting hole has the advantages of simple structure and easy implementation.

[0024] In one specific embodiment, there is a gap between the limiting protrusion and the sidewall of the limiting hole.

[0025] In this embodiment, as the rotating component rotates, it drives the sliding part to slide along the sliding groove. The movable component moves radially along the container lid under the influence of the sliding part. This creates a gap between the limiting protrusion and the sidewall of the limiting hole, providing space for the limiting protrusion to move axially relative to the limiting hole along the container lid. This ensures the movable component can move radially along the container lid under the influence of the sliding part, changing its position and thus altering the connection between the container lid and the container body. Simultaneously, when the movable component moves to the first position, the limiting protrusion can move to abut against the sidewall of the limiting hole, restricting the movable component from continuing to move radially away from the center of the container lid, preventing interference between the movable component and other components, and improving the reliability of the fit between the movable component and the container body. When the movable component moves to the second position, the limiting protrusion can move to abut against the sidewall of the limiting hole, restricting the movable component from continuing to move radially towards the center of the container lid, preventing interference between the movable component and other components.

[0026] In one specific embodiment, the cover includes a detachably connected upper cover and a lower cover, with the receiving cavity located between the upper cover and the lower cover.

[0027] In this embodiment, the cover includes a detachably connected upper cover and a lower cover, facilitating the installation and maintenance of the cover. Furthermore, the receiving cavity is located between the upper and lower covers, providing support for the movable component even if it is located between them, preventing it from falling off during use and affecting the normal operation of the container cover.

[0028] In one specific embodiment, the limiting portion is disposed on the upper cover.

[0029] In one specific embodiment, the top cover is provided with a first latching portion, and the rotating member is provided with a second latching portion. The first latching portion and the second latching portion cooperate to restrict the relative movement of the rotating member and the top cover along the axial direction of the container lid.

[0030] In this embodiment, the top cover is provided with a first latching part in the circumferential direction. The first latching part protrudes towards the rotating part in the radial direction of the container cover. The rotating part is provided with a second latching part in the circumferential direction at intervals. The second latching part protrudes towards the top cover in the radial direction of the container cover. When the first latching part and the second latching part are engaged, while ensuring that the rotating part and the top cover can rotate relative to each other, the relative movement of the rotating part and the top cover along the axial direction of the container cover can be restricted, so as to prevent the rotating part and the top cover from separating during relative rotation.

[0031] Secondly, this application provides a liquid container, the liquid container comprising: a container lid and a container body, the container lid being closed onto the container body; wherein, when the movable member is in the first position, the movable member engages with the side wall of the container body, and when the movable member is in the second position, the movable member disengages from the side wall of the container body.

[0032] In this embodiment, when the movable part is in the first position, the movable part can connect with the inner wall of the container body, thereby making the container lid and the container body connected; when the movable part is in the second position, the movable part can separate from the inner wall of the container body, thereby making the container lid and the container body separated.

[0033] In one specific embodiment, the first mating part is provided with a slot, and the second mating part is a protrusion. When the movable part is in the first position, the protrusion engages with the slot.

[0034] In this embodiment, the first mating part is a groove and the second mating part is a protrusion, which can improve the connection reliability when the first mating part and the second mating part are mated, and avoid the phenomenon that the container cap or container body will fall off due to the first mating part and the second mating part not being firmly connected during use. At the same time, making the first mating part a groove and the second mating part a protrusion can further improve the sealing performance of the container cap and the container body.

[0082] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0083] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0084] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0085] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0086] This application provides a container cap 11 and a liquid container 1 including the container cap 11, such as Figure 1 and Figure 2 As shown, the liquid container 1 also includes a container body 12, and a container lid 11 that can be closed onto the container body 12. Figure 3 As shown, the container lid 11 includes: a lid body 122, a rotating component 111, and a movable component 112. Please refer to... Figure 3 and Figure 4As shown, a portion of the rotating member 111 extends out of the cover 122 and is rotatable relative to the cover 122. The rotating member 111 is provided with a sliding groove 111a. The cover 122 has a receiving cavity 119, and the movable member 112 is located within the receiving cavity 119. The movable member 112 is movably connected to the rotating member 111. During rotation, the rotating member 111 can drive the movable member 112 to move radially away from the center of the container cover 11, placing the movable member 112 in a first position, or drive the movable member 112 radially towards the center of the container cover 11, placing the movable member 112 in a second position. The movable member 112, as shown... Figure 4 In the first position shown, the movable part 112 can be locked with the container body 12, that is, under the condition of no external force or a small external force, the movable part 112 and the container body 12 can remain connected. At this time, the container cover 11 and the container body 12 are in the following position. Figure 4 The first state shown is the position where the movable member 112 cooperates with the container body 12 to connect the container lid 11 and the container body 12, thereby enabling the container lid 11 and the container body 12 to maintain the connection state under the condition of no external force or a small external force. The movable member 112, in such a state... Figure 5 In the second position shown, the movable part 112 is released from the locking engagement with the container body 12. At this time, the container lid 11 and the container body 12 are in a second state, which is a state in which the container lid 11 can be detached from the container body 12.

[0087] In this embodiment, the user rotates the rotating component 111 to move the movable component 112 radially along the container lid 11, thereby moving the movable component 112 closer to or further away from the container body 12. That is, by switching the rotation of the rotating component 111 to the radial movement of the movable component 112, the connection and separation of the container lid 11 and the container body 12 can be achieved. There is no need to provide a threaded structure between the container lid 11 and the container body 12. Compared to the need for a threaded structure to connect or separate the container lid 11 from the container body 12, which requires a rotation angle of more than 360°, the rotation angle of the rotating component 111 is less than 360° when switching the radial movement of the movable component 112. Therefore, the container lid 11 in this embodiment has the advantages of being convenient, quick, and easy to use, improving the user experience. At the same time, a portion of the rotating component 111 extends out of the lid body 122, allowing the user to directly contact and rotate the rotating component 111 by hand.

[0088] The rotating part 111 extending out of the cover 122 has multiple protrusions 111e spaced apart on its side wall, which further improves the ease of operation.

[0089] In one specific embodiment, such as Figures 2 to 5As shown, the cover 122 may include a detachably connected upper cover 113 and a lower cover 114, with a receiving cavity 119 located between the upper cover 113 and the lower cover 114.

[0090] In this embodiment, the cover 122 includes a detachably connected upper cover 113 and a lower cover 114, which facilitates the installation and maintenance of the cover 122. Furthermore, the receiving cavity 119 is located between the upper cover 113 and the lower cover 114, providing support for the movable part 112 even when it is located between the upper cover 113 and the lower cover 114, preventing the movable part 112 from falling off during use and affecting the normal use of the container cover 11.

[0091] In other embodiments, the cover may also include only the upper cover 113 that can connect to the movable part 112, and the lower cover 114 may be omitted accordingly, as long as the movable part 112 can be installed.

[0092] In one specific embodiment, such as Figures 3 to 6 As shown, the rotating member 111 is provided with a sliding groove 111a, and the movable member 112 includes a body 112d and a sliding part 112a and a first mating part 112b disposed on the body 112d. The sliding part 112a is slidably engaged with the sliding groove 111a. During the rotation of the rotating member 111, it can drive the sliding part 112a to slide along the sliding groove 111a, thereby driving the movable member 112 to move radially away from or toward the center of the container cover 11, so that the movable member 112 is in a first position or a second position. In the first position, the first mating part 112b can engage with the container body 12, and in the second position, the first mating part 112b can disengage from the container body 12.

[0093] In this embodiment, when the rotating member 111 is rotated along the first direction X, the sliding groove 111a provided in the rotating member 111 slides into contact with the sliding part 112a provided in the movable member 112, causing the movable member 112 to move in a direction away from the center of the container lid 11, so that the movable member 112 is in a position such as Figure 4 The first position shown is such that the first mating part 112d of the movable member 112 is close to the side wall of the container body 12, allowing the first mating part 112b to engage with the container body 12, thereby achieving the engagement between the container lid 11 and the container body 12. When the rotating member 111 is rotated along the second direction Y, the sliding groove 111a provided in the rotating member 111 slides into contact with the sliding part 112a provided in the movable member 112, causing the movable member 112 to move toward the center of the container lid 11, thus positioning the movable member 112 in the following position. Figure 5 The second position shown is such that the first mating part 112d of the movable part 112 is away from the side wall of the container body 12, so that the first mating part 112b can be disengaged from the container body 12, thereby realizing the disengagement of the container lid 11 from the container body 12.

[0094] In other embodiments, the first direction X and the second direction Y can be interchanged, and the settings of the sliding groove 111a can be changed accordingly.

[0095] In one specific embodiment, such as Figure 6 As shown, a second mating part 121 is provided on the inner wall of the container body 12. When the movable part 112 is in the first position, the first mating part 112b and the second mating part 121 are mated, so that the movable part 112 is connected to the inner wall of the container body 12, thereby putting the container lid 11 and the container body 12 in a connected state. When the movable part 112 is in the second position, the first mating part 112b and the second mating part 121 are disengaged, so that the movable part 112 is separated from the inner wall of the container body 12, thereby putting the container lid 11 and the container body 12 in a separated state.

[0096] In this embodiment, the first mating part 112b may be provided with a slot, and the second mating part 121 may be a corresponding protrusion. When the movable part 112 is in the first position, the slot on the first mating part 112b moves to engage with the protrusion at the second mating part 121, so that the movable part 112 and the container body 12 are in a connected state. The engagement of the protrusion and the slot can restrict the relative movement of the container lid and the container body 12 along the axial direction, thereby keeping the container lid and the container body 12 in a connected state. When the movable part 112 is in the second position, the slot on the first mating part 112b moves to a position where it disengages from the protrusion at the second mating part 121, so that the movable part 112 and the container body 12 are in a separated state. The protrusion and the slot no longer restrict the relative movement of the container lid and the container body 12 along the axial direction, thereby keeping the container lid and the container body 12 in a separated state.

[0097] Figure 6 In the illustrated embodiment, the first mating part 112b is a groove and the second mating part 121 is a protrusion, which can improve the connection reliability when the first mating part 112b and the second mating part 121 are mated, and avoid the phenomenon that the container cap or container body 12 will fall off due to the first mating part 112b and the second mating part 121 not being firmly connected during use. At the same time, making the first mating part 112b a groove and the second mating part 121 a protrusion can further improve the sealing performance of the container cap and the container body 12.

[0098] In another specific embodiment, the first mating part can be a protrusion, and the second mating part can be a corresponding slot (not shown in the figure). The specific structure of the first mating part and the second mating part is not limited in this embodiment.

[0099] In one specific embodiment, such as Figure 6 and Figure 7As shown, the first mating part 112b is arc-shaped, and the shape of the first mating part 112b is similar to that of the second mating part 121. Therefore, when the first mating part 112b and the second mating part 121 are mated, the contact area of ​​the first mating part 112b and the second mating part 121 is increased, which further improves the connection reliability of the first mating part 112b and the second mating part 121, and can further improve the sealing performance of the container cap and the container body 12.

[0100] In one specific embodiment, such as Figure 8 and Figure 9 As shown, the sliding groove 111a includes a first mating position 111b and a second mating position 111c along its extending direction. The distance between the first mating position 111b and the rotation center of the rotating component 111 is L1, and the distance between the second mating position 111c and the rotation center of the rotating component 111 is L2, where L1 > L2. Simultaneously, as... Figure 11 and Figure 12 As shown, when the sliding part 112a is located at the first mating position 111b, the movable part 112 is in the first position, and when the sliding part 112a is located at the second mating position 111c, the movable part 112 is in the second position.

[0101] In this embodiment, as Figure 7 , Figure 9 and Figure 10 As shown, when the sliding part 112a slides from the second mating position 111c to the first mating position 111b, the distance L1 between the first mating position 111b and the rotation center of the rotating member 111 is relatively large. This results in a larger distance between the sliding part 112a located at the first mating position 111b and the rotation center of the rotating member 111. Consequently, the distance between the first mating part 112b connected to the sliding part 112a and the rotation center of the rotating member 111 is also relatively large. At this time, the movable member 112 is in the following position: Figure 4 The first position shown reduces the distance between the first mating part 112b and the inner wall of the container, allowing the first mating part 112b to engage with the second mating part, so that the container lid and the container body are in a connected state.

[0102] like Figure 7 , Figure 9 and Figure 11 As shown, when the sliding part 112a slides from the first mating position 111b to the second mating position 111c, the distance L2 between the second mating position 111c and the rotation center of the rotating member 111 is smaller. This results in a smaller distance between the sliding part 112a located at the second mating position 111c and the rotation center of the rotating member 111, which in turn results in a smaller distance between the first mating part 112b connected to the sliding part 112a and the rotation center of the rotating member 111. At this time, the movable member 112 is in the position shown in the figure. Figure 5The second position shown makes the distance between the first mating part 112b and the inner wall of the container larger, so that the first mating part 112b can be disengaged from the second mating part, so that the container lid and the container body are in a separated state.

[0103] In one specific embodiment, such as Figure 9 As shown, the sliding groove 111a is arc-shaped, and the center of the sliding groove 111a is offset from the rotation center of the rotating component 111.

[0104] In this embodiment, the sliding groove 111a is arc-shaped, which facilitates the sliding part sliding relative to the sliding groove 111a. This allows the rotating component 111 to be rotated without requiring a large force, improving the user experience. Furthermore, the center of the sliding groove 111a is offset from the rotation center of the rotating component 111, so that the sliding groove 111a has a first mating position 111b and a second mating position 111c. This allows the sliding part to move the movable component to either the first or second position when sliding relative to the sliding groove 111a, thereby switching the state of the container lid.

[0105] In one specific embodiment, such as Figure 9 As shown, the first mating position 111b and the second mating position 111c are located at both ends of the sliding groove 111a along its extension direction.

[0106] In this embodiment, the first mating position 111b and the second mating position 111c are located at both ends of the sliding groove 111a along its extension direction. When the rotating member 111 is rotated along the first direction X to put the container lid in the first state, the sliding part abuts against the side wall of the first mating position 111b, preventing it from continuing to rotate along the first direction X. When the rotating member 111 is rotated along the second direction Y to put the container lid in the second state, the sliding part abuts against the side wall of the second mating position 111c, preventing it from continuing to rotate along the second direction Y. Therefore, by placing the first mating position 111b and the second mating position 111c at both ends of the sliding groove 111a along its extension direction, it is convenient for the user to determine whether the rotating member 111 has been rotated into place to switch the state of the container lid.

[0107] In one specific embodiment, such as Figure 9 As shown, the central angle of the sliding groove is 15°-90°. The center of the arc-shaped sliding groove is offset from the rotation center of the rotating component.

[0108] For example, the central angle of the sliding groove can be 15°, 35°, 55°, 75°, 90°, etc. The central angle of the sliding groove 111a should not be too large or too small. If it is too large, the angle that the sliding part needs to rotate when switching between the first mating position 111b and the second mating position 111c is too large, thus requiring the user to rotate the rotating part 111 by an excessive angle, affecting ease of use. If it is too small, the difference between the distance L1 between the first mating position 111b and the rotation center of the rotating part 111 and the distance L2 between the second mating position 111c and the rotation center of the rotating part 111 is small, resulting in a smaller distance the moving part moves radially along the container lid, making it difficult to switch the mating relationship between the first and second mating parts. Therefore, when the central angle of the sliding groove 111a is within the range of 15°-90°, it is convenient to switch the mating relationship between the first and second mating parts without requiring the rotating part 111 to rotate by an excessive angle, improving ease of use.

[0109] In one specific embodiment, such as Figure 11 and Figure 13 As shown, a limiting part 115 may be provided on the cover, and a limiting mating part 112c may be provided on the body 112d of the movable part. The limiting part 115 and the limiting mating part 112c cooperate to restrict the rotation of the movable part 112.

[0110] In this embodiment, by setting the limiting part 115 and the limiting mating part 112c, the rotation of the movable part 112 can be restricted. That is, when the rotating part 111 rotates, and the sliding part 112a slides along the sliding groove 111a, the limiting part 115 and the limiting mating part 112c cooperate to restrict the movable part 112 from rotating under the drive of the sliding part 112a, and only moves radially along the container lid, thereby changing the position of the movable part 112 to change the mating state between the first mating part 112b and the second mating part.

[0111] The limiting part 115 can be provided on the upper cover 113 or the lower cover 114.

[0112] For example, in one specific embodiment, such as Figure 11 and Figure 12 As shown, the limiting part 115 is a limiting protrusion 120 provided on the upper cover 113, and the limiting mating part 112c is a limiting hole 123, which facilitates the snap-fit ​​engagement of the limiting part 115 and the limiting mating part 112c, and can improve the connection reliability of the limiting part 115 and the limiting mating part 112c, avoiding the phenomenon that the limiting part 115 and the limiting mating part 112c are not firmly snapped together during rotation, which would affect the normal use of the container lid. Moreover, making the limiting part 115 a limiting protrusion 120 and the limiting mating part 112c a limiting hole 123 has the advantages of simple structure and easy implementation.

[0113] The upper cover 113 may be provided with two or more limiting parts 115, and correspondingly, the movable part may be provided with two or more limiting mating parts 112c, thereby restricting the rotation of the movable part by means of the upper cover 113.

[0114] In another specific embodiment, the limiting part can also be a limiting protrusion (not shown in the figure) provided on the lower cover. The specific setting position of the limiting part is not limited in this embodiment.

[0115] In one specific embodiment, such as Figure 11 As shown, there is a gap between the limiting protrusion 120 and the sidewall of the limiting hole 123.

[0116] In this embodiment, during the rotation of the rotating member 111, when the sliding part 112a slides along the sliding groove 111a, the movable member 112 moves radially along the container lid under the action of the sliding part 112a. Therefore, along the radial direction of the container lid, a gap is formed between the limiting protrusion 120 and the side wall of the limiting hole 123, providing space for the limiting protrusion 120 to move relative to the limiting hole 123 along the axial direction of the container lid. This ensures that the movable member 112 can move radially along the container lid under the action of the sliding part 112a, thereby changing the position of the movable member and thus changing the connection state between the container lid and the container body. At the same time, when the movable member 112 moves to the first position, the limiting protrusion 120 can move to abut against the side wall of the limiting hole 123, thereby restricting the movable member 112 from continuing to move radially away from the center of the container lid 11, avoiding interference between the movable member 112 and other components, and improving the reliability of the fit between the movable member 112 of the container lid 11 and the container body 12. When the movable part 112 moves to the second position, the limiting protrusion 120 can move to abut against the side wall of the limiting hole 123, thereby restricting the movable part 112 from continuing to move radially toward the center of the container cover 11, and preventing the movable part 112 from interfering with other components.

[0117] like Figure 10 In the illustrated embodiment, the sliding part is located at the first mating position of the sliding groove, and the moving part is in the first position. For example... Figure 11 In the embodiment shown, the sliding part is located at the second mating position of the sliding groove, and the moving part is in the second position.

[0118] In one specific embodiment, such as Figures 7 to 11 As shown, the container lid includes two movable parts 112 arranged radially opposite to each other along the container lid, and the rotating part 111 includes two sliding grooves 111a; when the movable part 112 is in the first position, the two sliding parts 112a are respectively located at the first mating position 111b of the two sliding grooves 111a, and when the movable part 112 is in the second position, the two sliding parts 112a are respectively located at the second mating position 111c of the two sliding grooves 111a.

[0119] In this embodiment, by providing two radially opposite movable parts 112 and sliding grooves 111a, when the container lid and container body are in the connected state, the first mating parts 112b of both movable parts 112 can engage with the second mating parts, improving the connection reliability and stability of the first mating parts 112b and the second mating parts, thereby improving the connection reliability and stability of the container lid and container body and preventing the container lid or container body from falling off during use. Simultaneously, along the radial direction of the container lid, the first mating positions 111b of the two sliding grooves 111a are far apart, while the second mating positions 111c of the two sliding grooves 111a are close together. Furthermore, both sliding parts 112a are located at the same end of the two corresponding sliding grooves 111a, that is, both sliding parts 112a are simultaneously located at either the first mating position 111b or the second mating position 111c, allowing the rotating part 111 to rotate normally and preventing interference between the sliding grooves 111a and the sliding parts 112a when the rotating part 111 rotates.

[0120] In one specific embodiment, such as Figure 8 As shown, a groove 116 is provided between the two sliding grooves 111a.

[0121] In this embodiment, a groove 116 is provided between adjacent sliding grooves 111a, which can reduce the weight of the rotating part 111, thereby reducing the overall weight of the container lid, making it easier for users to pick up or place the container lid, and improving the user experience.

[0122] In one specific embodiment, such as Figure 13 As shown, the lower cover 114 has at least two first connecting holes 114a; the lower cover 114 also has a third mating part 114b and a fourth mating part 114c. Please refer to... Figure 5 and Figure 12 The upper cover is provided with a limiting protrusion 120, which corresponds to the position of the first connecting hole 114a. A portion of the structure of the first connecting hole 114a can extend into the limiting protrusion 120, allowing the upper cover 113 and the lower cover 114 to be connected by multiple screws. This further improves the connection reliability between the lower cover 114 and the upper cover 113, preventing separation of the upper cover 113 and lower cover 114 during use. Furthermore, the screws can be placed within the first connecting hole 114a, providing space for the screws and protecting them, thus extending their service life.

[0123] Meanwhile, the lower cover 114 is also provided with a third mating part 114b and a fourth mating part 114c. The third mating part 114b and the fourth mating part 114c can be annular recesses. The container cover can also include a sealing ring. The sealing ring is sleeved on the lower cover 114 and mates with the third mating part 114b and the fourth mating part 114c, which facilitates the positioning and installation of the sealing ring and improves the connection reliability between the sealing ring and the lower cover 114.

[0124] In one specific embodiment, such as Figure 8 , Figure 14 and Figure 15 As shown, the upper cover 113 is provided with a first locking part 113a, and the rotating member 111 is provided with a second locking part 111d. The first locking part 113a and the second locking part 111d cooperate to restrict the relative movement of the rotating member 111 and the upper cover 113 along the axial direction of the container cover.

[0125] In this embodiment, the upper cover 113 is provided with a first latching portion 113a in the circumferential direction. The first latching portion 113a protrudes towards the rotating member 111 in the radial direction of the container cover. The rotating member 111 is provided with a second latching portion 111d in the circumferential direction. The second latching portion 111d protrudes towards the upper cover 113 in the radial direction of the container cover. When the first latching portion 113a and the second latching portion 111d are latched together, while ensuring that the rotating member 111 and the upper cover 113 can rotate relative to each other, the relative movement of the rotating member 111 and the upper cover 113 along the axial direction of the container cover can be restricted, so as to prevent the rotating member 111 and the upper cover 113 from separating during relative rotation.

[0126] In addition, the first snap-fit ​​portion 113a is provided with a first guide surface 117, and the second snap-fit ​​portion 111d is provided with a second guide surface 118. The first guide surface 117 and the second guide surface 118 have opposite inclination angles along the axial direction of the container lid. During the process of installing the rotating member 111 onto the upper cover 113, the first guide surface 117 and the second guide surface 118 can abut against each other and play a guiding role, which facilitates the connection between the rotating member 111 and the upper cover 113.

[0127] In another specific embodiment, the second snap-fit ​​portion can be a continuous structure (not shown in the figure) arranged along the circumference of the rotating member. The specific structure of the second snap-fit ​​portion is not limited in this embodiment.

[0128] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
