Description

Technical Field

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

[0002] The liquid container includes a detachably connected container cover and a container body, and the container cover and the container body are usually connected by threads, and the container cover and the container body are sealed after being tightened by the threads. However, when using or cleaning, both hands are required to open or tighten the container cover, which affects the convenience of use. Utility Model Content

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

[0004] In a first aspect, the present application provides a container cover, comprising: a cover body, the cover body having a accommodating cavity; a rotating member, a portion of the structure of the rotating member extends out of the cover body and can rotate relative to the cover body; a movable member, the movable member is located in the accommodating cavity, and the movable member is movably connected to the rotating member; wherein, during the rotation of the rotating member, the movable member can be driven to move away from the center of the container cover in the radial direction of the container cover, so that the movable member is located in a first position, or the movable member can be driven to move toward the center of the container cover in the radial direction of the container cover, so that the movable member is located in 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 released from the locked cooperation with the container body.

[0005] In this embodiment, the user rotates the rotating member to move the movable member in the radial direction of the container cover, so that the movable member is close to or away from the container body, 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 achieved. There is no need to set a threaded structure between the container cover and the container body. Compared with the setting of the threaded structure to make the container cover and the container body connected or separated by an angle of 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 the embodiment of the present application has the advantages of being convenient and 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 the rotating member with his hand and rotate it.

[0006] In a specific embodiment, the rotating member is provided with a sliding groove, and the movable member includes a main body, a sliding portion and a first matching portion provided on the main body, and the sliding portion is slidably matched with the sliding groove; during the rotation of the rotating member, the sliding portion can be driven to slide along the sliding groove to drive the movable member to move radially away from or toward the center of the container cover, so that the movable member is in the first position or the second position; in the first position, the first matching portion can engage with the container body, and in the second position, the first matching portion can be disengaged from the container body.

[0007] In this embodiment, when the rotating member is rotated in a first direction, the sliding groove provided on the rotating member and the sliding part provided on the movable member are slidably matched, so that the movable member moves in a direction away from the center of the container cover, so that the movable member is in a first position, that is, the first matching part of the movable member is close to the side wall of the container body, so that the first matching part can be engaged with the container body, thereby realizing the matching of the container cover and the container body. When the rotating member is rotated in a second direction, the sliding groove provided on the rotating member and the sliding part provided on the movable member are slidably matched, so that the movable member moves in a direction toward the center of the container cover, so that the movable member is in a second position, that is, the first matching part of the movable member is away from the side wall of the container body, so that the first matching part can be disengaged from the container body, thereby realizing the disengagement of 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 matching position and a second matching position, the first matching position is at a distance L1 from the rotation center of the rotating member, the second matching position is at a distance L2 from the rotation center of the rotating member, and L1>L2; when the sliding portion is located at the first matching position, the movable member is in the first position, and when the sliding portion is located at the second matching position, the movable member is in the second position.

[0009] In this embodiment, when the sliding part slides from the second matching position to the first matching position, since the distance L1 between the first matching position and the rotation center of the rotating member is larger, the distance between the sliding part located at the first matching position and the rotation center of the rotating member 111 is larger, so that the first matching part connected to the sliding part is larger from the rotation center of the rotating member, and the movable part is in the first position at this time, so that the distance between the first matching part and the inner wall of the container body is smaller, 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 a connected state. When the sliding part slides from the first matching position to the second matching position, since the distance L2 between the second matching position and the rotation center of the rotating member is smaller, the distance between the sliding part located at the second matching position and the rotation center of the rotating member is smaller, so that the distance between the first matching part connected to the sliding part and the rotation center of the rotating member is smaller, and the movable part is in the second position at this time, so that the distance between the first matching part and the inner wall of the container body is larger, so that the first matching part can be released from the second matching part, so that the container cover and the container body are in a separated state.

[0010] In a specific embodiment, the sliding groove is in an arc shape, and the center of the sliding groove deviates from the rotation center of the rotating member.

[0011] In this embodiment, the sliding groove is made into an arc shape, so that the sliding part can slide relative to the sliding groove, so that the rotating part can be rotated without applying a large force, thereby improving the user's experience. The center of the sliding groove is deviated 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, it can drive the movable part to be located at the first position or the second position, thereby switching the state of the container cover.

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

[0013] In this embodiment, the central angle of the sliding groove should not be too large or too small. When it is too large, the sliding part needs to rotate too much when switching between the first matching position and the second matching position, so that the user needs to rotate the rotating member too much, 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 member and the distance L2 between the second matching position and the rotation center of the rotating member is small, so that the distance moved by the movable member along the radial direction of the container cover is small, 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 within the range of 15°-90°, it is convenient to switch the matching relationship between the first matching part and the second matching part, and there is no need to rotate the rotating member 111 too much, 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 its extension direction.

[0015] In this embodiment, the first matching position and the second matching position are located at the two ends of the sliding groove along its extension direction. When the rotating member is rotated along the first direction to put the container cover in the first state, the sliding part abuts against the side wall of the first matching position, so that it cannot continue to rotate in the first direction; when the rotating member is rotated along the second direction to put the container cover in the second state, the sliding part abuts against the side wall of the second matching position, so that it cannot continue to rotate in the second direction. Therefore, the first matching position and the second matching position are located at the two ends of the sliding groove along its extension direction, which is convenient for the user to judge whether the rotating member is rotated into place to switch the state of the container cover.

[0016] In a specific embodiment, the container cover includes two movable parts arranged opposite to each other along the radial direction of the container cover, and the rotating part includes two sliding grooves; when the movable part is in the first position, the two sliding parts are respectively located in the first matching positions of the two sliding grooves, and when the movable part is in the second position, the two sliding parts are respectively located in the second matching positions of the two sliding grooves.

[0017] In this embodiment, by providing two movable members and sliding grooves that are relatively distributed along the radial direction, when the container cover and the container body are in a connected state, the first matching parts of the two movable members can both match with the second matching parts, thereby improving the connection reliability and stability of the first matching parts and the second matching parts, thereby improving the connection reliability and stability of the container cover and the container body, and avoiding the phenomenon of the container cover or the container body falling off during use. At the same time, along the radial direction of the container cover, the first matching positions of the two sliding grooves are far away from each other, and the second matching positions of the two sliding grooves are close to each other. And the two sliding parts are both located at the same end of the two corresponding sliding grooves, that is, the two sliding parts are simultaneously located at the first matching position or the second matching position, so that the rotating member can rotate normally, and the sliding groove and the sliding part are prevented from interfering when the rotating member rotates.

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

[0019] In this embodiment, grooves are provided between adjacent sliding grooves, which can reduce the weight of the rotating member, thereby reducing the overall weight of the container cover, making it easier for users to take or place the container cover, and improving the user experience.

[0020] In a specific embodiment, the cover body is provided with a limiting portion, and the main body is provided with a limiting matching portion, and the limiting portion cooperates with the limiting matching portion to limit the rotation of the movable part.

[0021] In this embodiment, by providing a limiting portion and a limiting matching portion, the rotation of the movable part can be limited. That is, when the rotating part rotates, when the sliding part slides along the sliding groove, the limiting portion and the limiting matching portion cooperate to limit the rotation of the movable part driven by the sliding part, and only move along the radial direction of the container cover, thereby changing the position of the movable part to change the matching state of the first matching portion and the second matching portion.

[0022] In a specific embodiment, the limiting portion is a limiting protrusion provided on the cover body, and the limiting matching portion is a limiting hole.

[0023] In this embodiment, the limiting part is a limiting protrusion arranged on the cover body, and the limiting matching part is a limiting hole, which is convenient for the clamping fit between the limiting part and the limiting matching part, and can improve the connection reliability between the limiting part and the limiting matching part, and avoid the phenomenon that the limiting part and the limiting matching part are not firmly clamped during the rotation process, which affects the normal use of the container cover. In addition, the limiting part is a limiting protrusion and the limiting matching part is a limiting hole, which has the advantages of simple structure and easy implementation.

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

[0025] In this embodiment, when the rotating member drives the sliding part to slide along the sliding groove during the rotation of the rotating member, the movable member moves in the radial direction of the container cover under the drive of the sliding part, so that there is a gap between the limiting protrusion and the side wall of the limiting hole, which can provide space for the limiting protrusion to move along the axial direction of the container cover relative to the limiting hole, thereby ensuring that the movable member can move in the radial direction of the container cover under the drive of the sliding part to change the position of the movable member, thereby changing the connection state between the container cover and the container body. At the same time, when the movable member moves to the first position, the limiting protrusion can move to abut against the side wall of the limiting hole, thereby limiting the movable member from continuing to move away from the center of the container cover in the radial direction of the container cover, avoiding interference between the movable member and other components, and improving the reliability of the matching between the movable member of the container cover and the container body. When the movable member moves to the second position, the limiting protrusion can move to abut against the side wall of the limiting hole, thereby limiting the movable member from continuing to move toward the center of the container cover in the radial direction of the container cover, avoiding interference between the movable member and other components.

[0026] In a specific embodiment, the cover body includes an upper cover and a lower cover that are detachably connected, and the accommodating cavity is located between the upper cover and the lower cover.

[0027] In this embodiment, the cover body includes a detachably connected upper cover and a lower cover, which facilitates installation and maintenance of the cover body. The accommodating cavity is located between the upper cover and the lower cover, so that even if the movable part is located between the upper cover and the lower cover, support can be provided for the movable part to prevent the movable part from falling off during use, thereby affecting the normal use of the container cover.

[0028] In a specific embodiment, the limiting portion is arranged on the upper cover.

[0029] In a specific embodiment, the upper cover is provided with a first clamping portion, and the rotating member is provided with a second clamping portion, and the first clamping portion cooperates with the second clamping portion to limit the relative movement of the rotating member and the upper cover along the axial direction of the container cover.

[0030] In this embodiment, a first clamping portion is circumferentially arranged on the upper cover, and the first clamping portion protrudes toward the rotating part along the radial direction of the container cover. Second clamping portions are circumferentially arranged on the rotating part at intervals, and the second clamping portion protrudes toward the upper cover along the radial direction of the container cover. When the first clamping portion and the second clamping portion are engaged with each other, while ensuring that the rotating part and the upper cover can rotate relative to each other, the relative movement of the rotating part and the upper cover along the axial direction of the container cover can be limited, thereby avoiding separation of the rotating part and the upper cover during the relative rotation.

[0031] In a second aspect, the present application provides a liquid container, comprising: a container cover and a container body, wherein the container cover is engaged with the container body; wherein when the movable part is in the first position, the movable part cooperates with the side wall of the container body, and when the movable part is in the second position, the movable part releases the cooperation with the side wall of the container body.

[0032] In this embodiment, when the movable part is in the first position, the movable part can be connected to the inner wall of the container body, so that the container cover and the container body are in a connected state; when the movable part is in the second position, the movable part can be separated from the inner wall of the container body, so that the container cover and the container body are in a separated state.

[0033] In a specific embodiment, the first matching portion is provided with a slot, and the second matching portion is a protrusion, and when the movable member is in the first position, the protrusion is engaged with the slot.

[0034] In this embodiment, the first matching portion is a slot and the second matching portion is a protrusion, which can improve the connection reliability when the first matching portion and the second matching portion are matched, and avoid the phenomenon that the first matching portion and the second matching portion are not firmly connected during use, causing the container cover or the container body to fall off. At the same time, the first matching portion is a slot and the second matching portion is a protrusion, which can further improve the sealing of the container cover and the container body.

[0035] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0083] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0084] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0085] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0086] The embodiment of the present application provides a container cover 11 and a liquid container 1 including the container cover 11, such as Figure 1 and Figure 2 As shown, the liquid container 1 further comprises a container body 12, and a container cover 11 can be covered on the container body 12. Figure 3 As shown, the container cover 11 includes: a cover body 122, a rotating member 111 and a movable member 112. Figure 3 and Figure 4As shown, part of the structure of the rotating member 111 extends out of the cover body 122 and can rotate relative to the cover body 122, and the rotating member 111 is provided with a sliding groove 111a. The cover body 122 has a receiving cavity 119, and the movable member 112 is located in the receiving cavity 119. The movable member 112 is movably connected to the rotating member 111. During the rotation process, the rotating member 111 can drive the movable member 112 to move away from the center of the container cover 11 in the radial direction of the container cover 11, so that the movable member 112 is in the first position, or drive the movable member 112 to move toward the center of the container cover 11 in the radial direction of the container cover 11, so that the movable member 112 is in the second position. The movable member 112 is as shown in FIG. Figure 4 In the first position shown in FIG. 1 , the movable member 112 can be locked with the container body 12, that is, when there is no external force or the external force is small, the movable member 112 and the container body 12 can maintain a connection state. At this time, the container cover 11 and the container body 12 are in a state as shown in FIG. Figure 4 The first state shown in FIG. 1 is a position where the movable member 112 cooperates with the container body 12 to connect the container cover 11 to the container body 12, thereby enabling the container cover 11 and the container body 12 to maintain a connection state when there is no external force or when the external force is small. Figure 5 In the second position shown, the movable member 112 is unlocked from the container body 12 , and at this time, the container cover 11 and the container body 12 are in the second state, which is a state in which the container cover 11 can be separated from the container body 12 .

[0087] In this embodiment, the user rotates the rotating member 111 to move the movable member 112 along the radial direction of the container cover 11, so that the movable member 112 is close to or away from the container body 12, that is, the rotation of the rotating member 111 is switched to the radial movement of the movable member 112, so that the connection and separation of the container cover 11 and the container body 12 can be achieved. There is no need to set a threaded structure between the container cover 11 and the container body 12. Compared with the need to rotate an angle of more than 360° in the process of setting a threaded structure to connect or separate the container cover 11 from the container body 12, when the rotation of the rotating member 111 is switched to the radial movement of the movable member 112, the angle of rotation of the rotating member 111 is less than 360°. Therefore, the container cover 11 in the embodiment of the present application has the advantages of convenience and ease of use, which improves the user's experience. At the same time, a part of the structure of the rotating member 111 extends out of the cover body 122, which is convenient for the user to directly contact the rotating member 111 with his hand and rotate it.

[0088] Among them, a plurality of protrusions 111 e are arranged at intervals on the side wall of the rotating member 111 extending out of the cover body 122 , so as to further improve the convenience of operation.

[0089] In a specific embodiment, Figures 2 to 5As shown, the cover body 122 may include an upper cover 113 and a lower cover 114 that are detachably connected, and the accommodating cavity 119 is located between the upper cover 113 and the lower cover 114 .

[0090] In this embodiment, the cover body 122 includes a detachably connected upper cover 113 and a lower cover 114, which facilitates installation and maintenance of the cover body 122. The accommodating cavity 119 is located between the upper cover 113 and the lower cover 114, so that even if the movable member 112 is located between the upper cover 113 and the lower cover 114, support can be provided for the movable member 112 to prevent the movable member 112 from falling off during use, thereby affecting the normal use of the container cover 11.

[0091] In other embodiments, the cover body may also only include an upper cover 113 that can be connected 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 a specific embodiment, Figures 3 to 6 As shown, the rotating member 111 is provided with a sliding groove 111a, and the movable member 112 includes a main body 112d and a sliding portion 112a and a first matching portion 112b provided on the main body 112d, and the sliding portion 112a is slidably matched with the sliding groove 111a; during the rotation of the rotating member 111, the sliding portion 112a can be driven to slide along the sliding groove 111a to drive the movable member 112 to move away from or toward the center of the container cover 11 in the radial direction of the container cover 11, so that the movable member 112 is in the first position or the second position; in the first position, the first matching portion 112b can be engaged with the container body 12, and in the second position, the first matching portion 112b can be disengaged 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 on the rotating member 111 and the sliding portion 112a provided on the movable member 112 are slidably matched, so that the movable member 112 moves in a direction away from the center of the container cover 11, so that the movable member 112 is in a position as shown in FIG. Figure 4 In the first position shown, the first matching portion 112d of the movable member 112 is close to the side wall of the container body 12, so that the first matching portion 112b can be engaged with the container body 12, thereby achieving the matching of the container cover 11 and the container body 12. When the rotating member 111 is rotated along the second direction Y, the sliding groove 111a provided on the rotating member 111 and the sliding portion 112a provided on the movable member 112 are slidably matched, so that the movable member 112 moves toward the center of the container cover 11, so that the movable member 112 is in the position as shown in FIG. Figure 5 The second position shown, that is, the first matching portion 112 d of the movable member 112 is away from the side wall of the container body 12 , enables the first matching portion 112 b to be disengaged from the container body 12 , thereby achieving the disengagement of the container cover 11 from the container body 12 .

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

[0095] In a specific embodiment, Figure 6 As shown, a second matching portion 121 is provided on the inner wall of the container body 12. When the movable member 112 is in the first position, the first matching portion 112b matches with the second matching portion 121, so that the movable member 112 is connected to the inner wall of the container body 12, so that the container cover 11 and the container body 12 are in a connected state; when the movable member 112 is in the second position, the first matching portion 112b and the second matching portion 121 are released from matching, so that the movable member 112 is separated from the inner wall of the container body 12, so that the container cover 11 and the container body 12 are in a separated state.

[0096] In this embodiment, the first matching portion 112b can be provided with a slot, and the second matching portion 121 can be a corresponding protrusion. When the movable member 112 is in the first position, the slot on the first matching portion 112b moves to be engaged with the protrusion at the second matching portion 121, so that the movable member 112 and the container body 12 are in a connected state, and the cooperation between the protrusion and the slot can limit the relative movement between the container cover and the container body 12 along the axial direction, so that the container cover and the container body 12 are in a connected state; when the movable member 112 is in the second position, the slot on the first matching portion 112b moves to a position disengaged from the protrusion at the second matching portion 121, so that the movable member 112 and the container body 12 are in a separated state, and the protrusion and the slot no longer limit the relative movement between the container cover and the container body 12 along the axial direction, so that the container cover and the container body 12 are in a separated state.

[0097] Figure 6 In the illustrated embodiment, the first matching portion 112b is a slot and the second matching portion 121 is a protrusion, which can improve the connection reliability when the first matching portion 112b and the second matching portion 121 are matched, and avoid the phenomenon that the first matching portion 112b and the second matching portion 121 are not firmly connected during use, resulting in the container cover or the container body 12 falling off. At the same time, the first matching portion 112b is a slot and the second matching portion 121 is a protrusion, which can further improve the sealing of the container cover and the container body 12.

[0098] In another specific embodiment, the first matching portion may be a protrusion, and the second matching portion may be a corresponding slot (not shown in the figure). The specific structures of the first matching portion and the second matching portion are not limited in the embodiment of the present application.

[0099] In a specific embodiment, Figure 6 and Figure 7As shown, the first matching portion 112b is arc-shaped, and the shape of the first matching portion 112b is similar to that of the second matching portion 121, so that when the first matching portion 112b is matched with the second matching portion 121, the abutment area between the first matching portion 112b and the second matching portion 121 is increased, and the connection reliability between the first matching portion 112b and the second matching portion 121 is further improved, and the sealing performance of the container cover and the container body 12 can be further improved.

[0100] In a specific embodiment, Figure 8 and Fig. 9 As shown, the sliding groove 111a includes a first matching position 111b and a second matching position 111c along its extension direction. The first matching position 111b is at a distance L1 from the rotation center of the rotating member 111, and the second matching position 111c is at a distance L2 from the rotation center of the rotating member 111, and L1>L2. Fig.11 and Fig.12 As shown, when the sliding portion 112a is located at the first matching position 111b, the movable member 112 is at the first position, and when the sliding portion 112a is located at the second matching position 111c, the movable member 112 is at the second position.

[0101] In this embodiment, Figure 7 , Fig. 9 and Fig.10 As shown in FIG. 1 , when the sliding portion 112a slides from the second matching position 111c to the first matching position 111b, since the distance L1 between the first matching position 111b and the rotation center of the rotating member 111 is larger, the sliding portion 112a located at the first matching position 111b is at a larger distance from the rotation center of the rotating member 111, thereby making the first matching portion 112b connected to the sliding portion 112a at a larger distance from the rotation center of the rotating member 111. At this time, the movable member 112 is in a position as shown in FIG. Figure 4 The first position shown in the figure makes the distance between the first matching portion 112b and the inner wall of the container body smaller, so that the first matching portion 112b can match with the second matching portion, so that the container cover and the container body are in a connected state.

[0102] like Figure 7 , Fig. 9 and Fig.11 As shown in FIG. 1 , when the sliding portion 112a slides from the first matching position 111b to the second matching position 111c, since the distance L2 between the second matching position 111c and the rotation center of the rotating member 111 is smaller, the distance between the sliding portion 112a located at the second matching position 111c and the rotation center of the rotating member 111 is smaller, so that the distance between the first matching portion 112b connected to the sliding portion 112a and the rotation center of the rotating member 111 is smaller. At this time, the movable member 112 is in the position shown in FIG. Figure 5The second position shown in the figure makes the distance between the first matching portion 112b and the inner wall of the container body larger, so that the first matching portion 112b can be released from the second matching portion, so that the container cover and the container body are in a separated state.

[0103] In a specific embodiment, Fig. 9 As shown, the sliding groove 111 a is in an arc shape, and the center of the sliding groove 111 a deviates from the rotation center of the rotating member 111 .

[0104] In this embodiment, the sliding groove 111a is made into an arc shape, so that the sliding part can slide relative to the sliding groove 111a, so that the rotating member 111 can be rotated without applying a large force, thereby improving the user's experience. The center of the sliding groove 111a is deviated from the rotation center of the rotating member 111, so that the sliding groove 111a has a first matching position 111b and a second matching position 111c, so that when the sliding part slides relative to the sliding groove 111a, it can drive the movable member to be located at the first position or the second position, thereby switching the state of the container cover.

[0105] In a specific embodiment, Fig. 9 As shown, the first matching position 111b and the second matching position 111c are located at two ends of the sliding groove 111a along its extending direction.

[0106] In this embodiment, the first matching position 111b and the second matching position 111c are located at the two 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 cover in the first state, the sliding portion abuts against the side wall of the first matching position 111b, so that it cannot continue to rotate along the first direction X; when the rotating member 111 is rotated along the second direction Y to put the container cover in the second state, the sliding portion abuts against the side wall of the second matching position 111c, so that it cannot continue to rotate along the second direction Y. Therefore, the first matching position 111b and the second matching position 111c are located at the two ends of the sliding groove 111a along its extension direction, which is convenient for the user to judge whether the rotating member 111 is rotated into place to switch the state of the container cover.

[0107] In a specific embodiment, Fig. 9 As shown, the center angle of the sliding groove is 15°-90°. The center of the arc-shaped sliding groove deviates from the rotation center of the rotating member.

[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. When it is too large, the sliding part needs to rotate too much when switching between the first matching position 111b and the second matching position 111c, so that the user needs to rotate the rotating member 111 too much, which affects the convenience of use; when it is too small, the difference between the distance L1 between the first matching position 111b and the rotation center of the rotating member 111 and the distance L2 between the second matching position 111c and the rotation center of the rotating member 111 is small, so that the distance moved by the movable member along the radial direction of the container cover is small, 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 111a is within the range of 15°-90°, it is convenient to switch the matching relationship between the first matching part and the second matching part, and there is no need to rotate the rotating member 111 too much, which improves the convenience of use.

[0109] In a specific embodiment, Fig.11 and Fig.13 As shown, a limit portion 115 may be provided on the cover body, and a limit matching portion 112c may be provided on the body 112d of the movable member. The limit portion 115 matches with the limit matching portion 112c to limit the rotation of the movable member 112.

[0110] In this embodiment, by providing the limiting portion 115 and the limiting matching portion 112c, the rotation of the movable member 112 can be limited. That is, when the rotating member 111 rotates, when the sliding portion 112a slides along the sliding groove 111a, the limiting portion 115 and the limiting matching portion 112c cooperate to limit the movable member 112 from rotating under the drive of the sliding portion 112a, and only move along the radial direction of the container cover, thereby changing the position of the movable member 112 to change the matching state of the first matching portion 112b and the second matching portion.

[0111] The limiting portion 115 may be disposed on the upper cover 113 or the lower cover 114 .

[0112] For example, in a specific embodiment, Fig.11 and Fig.12 As shown, the limiting portion 115 is a limiting protrusion 120 arranged on the upper cover 113, and the limiting matching portion 112c is a limiting hole 123, which is convenient for the clamping fit between the limiting portion 115 and the limiting matching portion 112c, and can improve the connection reliability between the limiting portion 115 and the limiting matching portion 112c, and avoid the phenomenon that the limiting portion 115 and the limiting matching portion 112c are not firmly clamped during the rotation process, which affects the normal use of the container cover. In addition, the limiting portion 115 is a limiting protrusion 120 and the limiting matching portion 112c is a limiting hole 123, which has the advantages of simple structure and easy implementation.

[0113] The upper cover 113 may be provided with two or more limiting portions 115 , and correspondingly, the movable member may be provided with two or more limiting matching portions 112 c , so as to limit the rotation of the movable member through the upper cover 113 .

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

[0115] In a specific embodiment, Fig.11 As shown, there is a gap between the limiting protrusion 120 and the side wall of the limiting hole 123.

[0116] In this embodiment, when the rotating member 111 rotates and drives the sliding portion 112a to slide along the sliding groove 111a, the movable member 112 moves along the radial direction of the container cover under the drive of the sliding portion 112a. Therefore, along the radial direction of the container cover, there is a gap between the limiting protrusion 120 and the side wall of the limiting hole 123, which can provide space for the limiting protrusion 120 to move along the axial direction of the container cover relative to the limiting hole 123, thereby ensuring that the movable member 112 can move along the radial direction of the container cover under the drive of the sliding portion 112a to change the position of the movable member, thereby changing the connection state between the container cover 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 limiting the movable member 112 from continuing to move away from the center of the container cover 11 along the radial direction of the container cover 11, avoiding interference between the movable member 112 and other components, and improving the reliability of the matching between the movable member 112 of the container cover 11 and the container body 12. When the movable member 112 moves to the second position, the limiting protrusion 120 can move to abut against the side wall of the limiting hole 123, thereby limiting the movable member 112 from continuing to move along the radial direction of the container cover 11 toward the center of the container cover 11, avoiding interference between the movable member 112 and other components.

[0117] like Fig.10 In the embodiment shown, the sliding portion is located at the first matching position of the sliding groove, and the movable member is in the first position. Fig.11 In the illustrated embodiment, the sliding portion is located in the second matching position of the sliding groove, and the movable member is in the second position.

[0118] In a specific embodiment, Figures 7 to 11 As shown, the container cover includes two movable parts 112 arranged opposite to each other along the radial direction of the container cover, 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 matching positions 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 matching positions 111c of the two sliding grooves 111a.

[0119] In this embodiment, by providing two movable members 112 and sliding grooves 111a that are relatively distributed along the radial direction, when the container cover and the container body are in a connected state, the first matching parts 112b of the two movable members 112 can both match with the second matching parts, thereby improving the connection reliability and stability of the first matching parts 112b and the second matching parts, thereby improving the connection reliability and stability of the container cover and the container body, and avoiding the phenomenon of the container cover or the container body falling off during use. At the same time, along the radial direction of the container cover, the first matching positions 111b of the two sliding grooves 111a are far away from each other, and the second matching positions 111c of the two sliding grooves 111a are close to each other. And the two sliding parts 112a are both located at the same end of the two corresponding sliding grooves 111a, that is, the two sliding parts 112a are simultaneously located at the first matching position 111b or the second matching position 111c, so that the rotating member 111 can rotate normally, and when the rotating member 111 rotates, the sliding groove 111a and the sliding part 112a are prevented from interfering.

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

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

[0122] In a specific embodiment, Fig.13 As shown, at least two first connection holes 114a are provided on the lower cover 114; a third matching portion 114b and a fourth matching portion 114c are also provided on the lower cover 114. Figure 5 and Fig.12 The upper cover is provided with a limiting protrusion 120, which corresponds to the position of the first connection hole 114a, and a part of the structure of the first connection hole 114a can extend into the limiting protrusion 120, and the upper cover 113 and the lower cover 114 can be connected by multiple screws, further improving the connection reliability of the lower cover 114 and the upper cover 113, and avoiding the phenomenon of separation of the upper cover 113 and the lower cover 114 during use. The screws can be set in the first connection hole 114a, providing a placement space for the screws, and can protect the screws and extend their service life.

[0123] At the same time, a third matching portion 114b and a fourth matching portion 114c are also provided on the lower cover 114. The third matching portion 114b and the fourth matching portion 114c can be annular recessed portions. The container cover can also include a sealing ring, which is sleeved on the lower cover 114 and cooperates with the third matching portion 114b and the fourth matching portion 114c to facilitate the positioning and installation of the sealing ring and improve the connection reliability between the sealing ring and the lower cover 114.

[0124] In a specific embodiment, Figure 8 , Fig.14 and Fig.15 As shown, the upper cover 113 is provided with a first clamping portion 113a, and the rotating member 111 is provided with a second clamping portion 111d. The first clamping portion 113a cooperates with the second clamping portion 111d to limit 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 circumferentially provided with a first clamping portion 113a, which protrudes toward the rotating member 111 along the radial direction of the container cover, and the rotating member 111 is circumferentially provided with second clamping portions 111d at intervals, which protrude toward the upper cover 113 along the radial direction of the container cover. When the first clamping portion 113a and the second clamping portion 111d are engaged with each other, 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 limited, thereby avoiding separation of the rotating member 111 and the upper cover 113 during the relative rotation.

[0126] In addition, the first clamping portion 113a is provided with a first guide surface 117, and the second clamping 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 cover. In the process of installing the rotating member 111 to 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, thereby facilitating the connection between the rotating member 111 and the upper cover 113.

[0127] In another specific embodiment, the second clamping portion may be a continuous structure arranged along the circumference of the rotating member (not shown in the figure). The specific structure of the second clamping portion is not limited in the embodiment of the present application.

[0128] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
