Description

TECHNICAL FIELD

[0001] The utility model belongs to cup cover technical field, especially relate to a prevent that cup assembly's structure and container fell off. BACKGROUND

[0002] When driving a car, a special cup is usually equipped on the car to facilitate the driver to drink. This special cup is often called a car cup. Since the driver needs to drive the car, he can only operate the car cup with one hand.

[0003] The earliest car cup is directly open to facilitate the driver to operate, and the driver can directly drink the water in the cup. However, dust inside the car can easily fall directly into the cup from the opening, causing the water in the cup to mix with dust. To solve the dust problem, the car cup has been innovated in design and introduced a dust cover to improve the hygiene of use. After introducing the dust cover, how to conveniently open and close with one hand has become the design focus of the car cup. Among them, the sliding cover type cup cover that uses a sliding mechanism to realize opening and closing is widely welcomed due to its convenience for one-handed operation.

[0004] For example, in the elastic opening and closing cup cover provided in patent CN217565584U, a sliding groove is provided on the cover body, one end of the sliding groove is provided with a drinking port, and a sliding cover is slidably arranged in the sliding groove. A closing positioning groove and an opening positioning groove are sequentially arranged on the side wall of the sliding groove, and a resilient wall is protrudingly arranged on one side of the sliding cover. When the sliding cover is slid to the position where the resilient arm is arranged in the closing positioning groove, the sliding cover covers the drinking port so that the liquid in the cup will not flow out from the drinking port. When the sliding cover is slid to the position where the resilient arm is in the opening positioning groove, the sliding cover does not cover the drinking port, and the drinking port is exposed, so that the driver can drink the liquid in the cup through the drinking port.

[0005] The cup cover described above can be held by the driver when in use, and the driver can push the sliding cover with his fingers to perform opening or closing operation, which is simple and convenient to operate.

[0006] However, as time goes by, more and more people begin to integrate the car cup used in the car into daily life - such as for outdoor, garage, office, etc., making it a convenient and practical household item. The continuous expansion of the use scene of the car cup prompts users to have higher and more diversified demands for its functions.

[0007] However, although the opening and closing operation of the slider cup cover is simple, the slider cover is easy to fall off due to collision and the like (for example, the user holds the cup in hand and accidentally collides with a person to cause the cup to fall out of hand, or the cup is placed on the table and falls off from the table after being collided). The slider cover is attached to the cover body by magnetic force, and the greater the magnetic force, the more firmly the slider cover is installed on the cover body. However, the increase of the magnetic force will also increase the friction of the slider cover when sliding, so in order to facilitate the opening and closing operation of the user, the magnetic force cannot be set too large. This causes the slider cover not to separate from the cover body under normal circumstances, but when encountering collision and the like, the slider cover is easy to fall off from the cover body, and after falling off, it is easy to be lost due to the small size of the slider cover.

DETAILED DESCRIPTION

[0042] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the specific implementation manners of the utility model will be described below with reference to the drawings. Obviously, the drawings described below are only some embodiments of the utility model, and other drawings and other implementation manners can be obtained by those skilled in the art without creative labor on the basis of these drawings.

[0043] In order to make the drawing simple, only the parts related to the utility model are schematically represented in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and convenient to understand, in some drawings, only one of the parts with the same structure or function is schematically represented, or only one of them is marked. In this paper, "one" not only means "only one", but also can mean "more than one" situation.

[0044] Referring to Figures 1 to 14The embodiment provides a container with a cover assembly and a separation-preventing structure of the cover assembly. The cover assembly comprises a cover body 1, a sliding cover 2 and at least one separation-preventing unit. The cover body 1 is provided with a drinking opening 4. The sliding cover 2 is arranged on the cover body 1 and is configured to slide between a closed position and an open position on the cover body 1. When the sliding cover 2 is in the closed position, the sliding cover 2 covers the drinking opening 4; when the sliding cover is in the open position, the sliding cover 2 is away from the drinking opening, and meanwhile, an air hole 31 on the cover body 1 is in a ventilation state. The sliding cover 2 and the cover body 1 are magnetically detachably connected.

[0045] The separation-preventing unit comprises a clamping groove and a clamping block 23, and any one of the clamping groove and the clamping block is arranged on the cover body 1, and the other is arranged on the sliding cover 2; when the sliding cover 2 slides to the closed position, the clamping block 23 is clamped with the clamping groove.

[0046] When the container with the cover assembly falls from a high place (for example, the container is held in the hand of a user and is accidentally collided with a person to cause the container to fall from the hand, or the container is placed on a table and is collided to fall from the table), the separation-preventing unit can effectively prevent the sliding cover 2 from separating from the cover body 1. If the sliding cover 2 separates from the cover body 1, the sliding cover 2 is small in size and is easy to be lost because it cannot be found.

[0047] For convenience of description, the combination of the cover body 1 and the sliding cover 2 is referred to as a cover assembly. The cover assembly is generally used in cooperation with a containing piece. The cover body 1 in the cover assembly is threadedly connected or coveringly connected to an opening of the containing piece to form a container (in addition to the cover assembly and the containing piece, other components can be added according to actual needs in the container); for example, the containing piece can be a cup body or a bottle body, and the cover assembly is connected to a cup opening of the cup body or a bottle opening of the bottle body to form a cup or a bottle with a cover. The content in the containing piece can leave from the drinking opening 4 on the cover body 1.

[0048] When the user uses the container, if the content needs to be poured out (for example, the content is water, and the user needs to drink the water), the sliding cover 2 on the cover body 1 can be slid to the open position, and the user can pour the content out of the drinking opening 4; when the content does not need to be poured out (for example, the user does not need to drink the water), the sliding cover 2 can be slid to the closed position, and in this state, the sliding cover 2 covers the drinking opening on the cover body 1 to seal the drinking opening, so that the container does not have the phenomenon that the content flows out of the drinking opening 4 in a pouring state. It should be noted that, although the container in the technical scheme provided by the embodiment is commonly used for containing liquid such as drinking water, the container can also be used for containing solid particles, and the shape of the containing piece and the type of the content contained are not limited in the embodiment.

[0049] As shown in FIG. 1, the cover assembly comprises a cover body 1, a sliding cover 2 and at least one separation-preventing unit. The cover body 1 is provided with a drinking opening 4. The sliding cover 2 is arranged on the cover body 1 and is configured to slide between a closed position and an open position on the cover body 1. When the sliding cover 2 is in the closed position, the sliding cover 2 covers the drinking opening 4; when the sliding cover is in the open position, the sliding cover 2 is away from the drinking opening, and meanwhile, an air hole 31 on the cover body 1 is in a ventilation state. The sliding cover 2 and the cover body 1 are magnetically detachably connected. Figure 2As shown, when the cover body 1 is placed on a horizontal plane, the upper side of the cover body 1 is the first side of the cover body 1, the lower side of the cover body 1 is the second side of the cover body 1, the upward direction is the first side direction of the cover body 1, and the downward direction is the second side direction of the cover body 1. The sliding direction of the sliding cover 2 in the process of sliding from the open position to the closed position is the first direction, and the sliding direction of the sliding cover 2 in the process of sliding from the closed position to the open position is the second direction.

[0050] Specifically, the first side of the cover body 1 is provided with a sliding groove 7, the groove bottom surface 8 of the sliding groove 7, and the drinking opening 4 provided on the groove bottom surface 8 of the sliding groove 7. The drinking opening 4 is a through hole penetrating the first side and the second side of the cover body 1; the sliding cover 2 is slidably arranged in the sliding groove 7. At least one side wall of the sliding groove 7 is sequentially provided with a closed positioning groove 9 and an open positioning groove 10, and at least one side of the sliding cover 2 is provided with an elastic arm 11. When the elastic arm 11 is located in the closed positioning groove 9, the sliding cover 2 is in the closed position, and when the elastic arm 11 is located in the open positioning groove 10, the sliding cover 2 is in the open position. In this embodiment, preferably, both side walls of the sliding groove 7 are sequentially provided with a closed positioning groove 9 and an open positioning groove 10, and both sides of the sliding cover 2 are provided with an elastic arm 11; more preferably, the elastic arms 11 on both sides of the sliding cover 2 are symmetrically arranged, and the closed positioning grooves 9 and the open positioning grooves 10 on the side walls of the sliding groove 7 are also symmetrically arranged.

[0051] As shown in the drawings, Figure 7 The elastic arm 11 is connected with the connecting arm 12 at both ends in the sliding direction of the sliding cover 2, and the other end of the connecting arm 12 not connected with the elastic arm 11 is connected with the sliding cover 2, that is, both ends of the elastic arm 11 are connected with the sliding cover 2 through the connecting arm 12. The elastic arm 11 and the connecting arm 12 have a gap 13 between the side wall of the sliding cover 2, and the gap 13 is used for elastic deformation of the elastic arm 11 and the connecting arm 12. When the sliding cover 2 slides between the closed position and the open position, the elastic arm 11 elastically deforms towards the gap 13, so that the elastic arm 11 can slide out of the closed positioning groove 9 or the open positioning groove 10 and slide in the non-closed positioning groove area and the non-open positioning groove area on the side wall of the sliding groove 7.

[0052] The groove bottom surface 8 of the sliding groove 7 is provided with a clamping piece 22 protruding from the groove bottom surface 8 to the first side direction of the cover body 1 by a certain distance and then bent to the second direction, so that the clamping piece 22 cooperates with the groove bottom surface 8 to form a clamping groove facing the second direction. In the process of sliding the sliding cover 2 from the open position to the closed position, the clamping block 23 extends into the clamping groove.

[0053] As shown in the drawings, Figure 12As shown, the engaging block 23 can be arranged at the joint of the connecting arm 12 and the sliding cover 2. The engaging member 22 can be protruded from the groove bottom surface 8 and extended into the gap 13, i.e. the engaging member 22 is arranged in the gap 13. Preferably, two anti-disengagement units can be arranged between the cover body 1 and the sliding cover 2, and two engaging members 22 are arranged on the groove bottom surface 8 of the sliding groove 7.

[0054] The sliding cover 2 is provided with the elastic sealing member 3, and the elastic sealing member 3 moves when the sliding cover 2 slides. When the sliding cover 2 is in the closed position, the sliding cover 2 covers the drinking opening 4 and the elastic sealing member 3 covers the drinking opening 4; when the sliding cover 2 is in the open position, the sliding cover 2 and the elastic sealing member 3 are both away from the drinking opening 4, and the air hole 31 on the cover body 1 is in the air state. When the sliding cover 2 slides to the closed position, the sliding cover 2 covers the drinking opening 4 on the cover body 1 and the elastic sealing member 3 covers the drinking opening 4, and the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4, thereby sealing the drinking opening 4, so that the container does not leak when it is in the pouring state.

[0055] The magnetic detachable connection between the sliding cover 2 and the cover body 1 can be, for example, as described in the background art, a first magnet 5 is arranged on the sliding cover 2 and a second magnet 6 is arranged on the cover body 1, the first magnet 5 and the second magnet 6 are attracted to each other, thereby attracting the sliding cover 2 to the cover body 1. Figure 14

[0056] When the sliding cover 2 is in the closed position, the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4 on the cover body 1, and the sliding cover 2 presses the elastic sealing member 3 tightly (and needs the elastic sealing member 3 to be elastically deformed), thereby realizing that the elastic sealing member 3 seals the drinking opening 4. There are many ways to make the sliding cover 2 press the elastic sealing member 3 tightly at the drinking opening 4 on the cover body 1 when the sliding cover 2 is in the closed position, for example, using the first magnet 5 and the second magnet 6 that generate a large enough magnetic force. This way, no other structural improvements are needed for the cover assembly, only the first magnet 5 and the second magnet 6 that can generate a larger magnetic force need to be replaced, which is friendly to the production process, but also has other shortcomings - the first magnet 5 and the second magnet 6 with a larger magnetic force are relatively high in cost. In this embodiment, the guiding and pressing structure is arranged to make the sliding cover 2 press the elastic sealing member 3 tightly at the drinking opening 4 on the cover body 1 when the sliding cover 2 is in the closed position.

[0057] Specifically, the guiding and pressing structure can guide the part of the sliding cover 2 provided with the elastic sealing member 3 to move towards the second side of the cover body 1 during the sliding of the sliding cover 2 to the closed position, so that the sliding cover 2 can press the elastic sealing member 3 tightly on the cover body 1 when the sliding cover 2 is in the closed position, thereby realizing the sealing of the drinking opening 4 by the elastic sealing member 3.

[0058] ​For the convenience of description, the stroke of sliding the cover 2 from the open position to the closed position is referred to as the first stroke, and the stroke of sliding the cover 2 to the closed position under the guidance of the guide and pressing structure is referred to as the second stroke. The second stroke is equal to the first stroke or is a part of the first stroke. Preferably, the second stroke is a part of the first stroke and is located at the end of the first stroke.

[0059] The guide and pressing structure comprises at least one guide and pressing assembly, and the guide and pressing assembly comprises a first guide portion and a second guide portion. The first guide portion is arranged on the cover body 1, and the second guide portion is arranged on the cover 2 and moves synchronously with the cover 2. In the second stroke, the first guide portion and the second guide portion are in sliding connection, and the second guide portion is located in the direction of the second side of the cover body 1 relative to the first guide portion. The first guide portion and the second guide portion are configured to, in the second stroke, move the second guide portion to the second side of the cover body 1 when the second guide portion slides under the limitation of the first guide portion.

[0060] Specifically, at least one of the first guide portion and the second guide portion is a guide surface. When the first guide portion is the guide surface, the first guide portion is a guide surface arranged in the direction of the second side of the cover body 1; when the second guide portion is the guide surface, the second guide portion is a guide surface arranged in the direction of the first side of the cover body 1. The guide surface is offset in the first direction to the second side of the cover body 1, and the specific offset manner can be offset in a planar manner (i.e., an inclined plane), offset in a curved surface manner (i.e., the farther the curved surface goes in the first direction, the closer it gets to the second side of the cover body 1), or offset in a combination of a planar and a curved surface manner, etc., and the specific manner is not limited.

[0061] When the first guide portion on the cover body 1 is the guide surface, in the second stroke, the second guide portion moves synchronously with the cover 2, and the second guide portion slides against the guide surface (i.e., the first guide portion) when the cover 2 slides in the first direction. Since the guide surface is offset in the first direction to the second side of the cover body 1, the second guide portion will gradually move to the second side of the cover body 1 under the limitation of the guide surface, thereby driving the cover 2 to move to the second side of the cover body 1.

[0062] When the second guide portion on the cover 2 is the guide surface, in the second stroke, the guide surface will abut against the first guide portion when the cover 2 slides in the first direction. Since the guide surface is offset in the first direction to the second side of the cover body 1, in the process of moving in the first direction with the cover 2, the part of the guide surface abutting against the second guide portion is gradually offset to the first side of the cover body 1 relative to the cover 2. Since the first guide portion is fixed on the cover body 1 and does not change in position, in the process of moving in the first direction with the cover 2, the guide surface will gradually move to the second side of the cover body 1, thereby driving the cover 2 to move to the second side of the cover body 1.

[0063] When the first guide portion on the cover body 1 and the second guide portion on the sliding cover 2 are both guide surfaces, in the second stroke, the second guide portion slides along the first guide portion in the process of the sliding cover 2 moving in the first direction, and gradually moves to the second side of the cover body 1 in the process of sliding, thereby driving the sliding cover 2 to move to the second side of the cover body 1.

[0064] In the second stroke, the distance of the part of the sliding cover 2 on which the elastic sealing member 3 is arranged moving in the direction perpendicular to the groove bottom surface 8 of the sliding groove 7 is less than the distance of the elastic sealing member 3 protruding from the sliding cover 2, so that the sliding cover 2 can press the elastic sealing member 3 tightly at the drinking opening 4 of the cover body 1 and press the elastic sealing member 3 to be elastically deformed when in the closed position, thereby sealing the drinking opening 4. The distance of the elastic sealing member 3 protruding from the sliding cover 2 is small, so the distance of the part of the sliding cover 2 on which the elastic sealing member 3 is arranged moving in the direction perpendicular to the groove bottom surface 8 of the sliding groove 7 in the second stroke is also small, which is generally selected to be within 5 mm, and preferably about 0.6 mm; of course, the distance of the part of the sliding cover 2 on which the elastic sealing member 3 is arranged moving in the direction perpendicular to the groove bottom surface 8 of the sliding groove 7 in the second stroke is also needed to be adjusted according to the actual situation.

[0065] The sliding distance of the sliding cover 2 in the process of sliding from the open position to the closed position is small, so the distance of the part of the sliding cover 2 on which the elastic sealing member 3 is arranged moving in the plane parallel to the groove bottom surface 8 of the sliding groove 7 is also small, which is generally selected to be within 10 mm, and preferably about 2 mm.

[0066] In this way, the use of the sliding cover 2 will not affect the user's hand feeling during the process of pushing the sliding cover 2.

[0067] The part of the inner side wall of the sliding groove 7 located on both sides of the sliding direction of the sliding cover 2 is the sliding inner side wall 14, and the closing positioning groove 9 and the opening positioning groove 10 are arranged on the sliding inner side wall 14; the part of the outer side wall of the sliding cover 2 located on both sides of the sliding direction of the sliding cover 2 is the sliding outer side wall 15.

[0068] The guide and pressing-down structure in the embodiment includes a first guide and pressing-down assembly, a second guide and pressing-down assembly, and the above-mentioned anti-dropping unit, wherein the first guide and pressing-down assembly plays a main guide and pressing-down role (the guide and pressing-down role is the role of driving the sliding cover 2 to move to the second side of the cover body 1 in the second stroke), and the second stroke refers to the stroke of the sliding cover 2 sliding under the limitation of the first guide and pressing-down assembly in the process of sliding from the open position to the closed position.

[0069] The first guiding and pressing assembly comprises a guiding groove 16 and a guiding protrusion 17, either of which is arranged on the sliding inner side wall 14, and the other is arranged on the sliding outer side wall 15. During the sliding of the sliding cover 2 from the open position to the closed position, at least part of the sliding process, the guiding protrusion 17 is slidably connected in the guiding groove 16; specifically, the guiding protrusion 17 is slidably connected in the guiding groove 16 during the second stroke. The guiding groove 16 is offset to the second side of the cover body 1 in the first direction.

[0070] Specifically, in the present embodiment, the two sliding inner side walls 14 of the sliding groove 7 are respectively provided with a first guiding and pressing assembly in cooperation with the corresponding sliding outer side wall 15. Moreover, when the sliding cover 2 is in the closed position, the two sides of the drinking opening 4 in the first direction are respectively provided with a first guiding and pressing assembly; thus, when the sliding cover 2 is in the closed position, the first guiding and pressing assemblies on both sides of the drinking opening 4 can well apply force to the sliding cover 2, so that the sliding cover 2 presses the elastic sealing member 3 at the drinking opening 4, so that the elastic sealing member 3 seals the drinking opening 4, preventing the contents in the container from flowing out. Among them, in the first guiding and pressing assembly, the inner side wall of the guiding groove 16 on the sliding cover 2 close to the second side of the cover body 1 (that is, the inner side wall of the guiding groove 16 facing the first side of the cover body 1, which is the inner side wall of the guiding protrusion 17 on the second side of the cover body 1) is the guiding surface mentioned above.

[0071] The end of the guiding groove 16 in the first direction can be provided with an opening, and the opening is used for the guiding protrusion 17 to slide into the guiding groove 16 from the opening during the sliding of the sliding cover 2 in the first direction.

[0072] The part of the inner side wall of the sliding groove 7 located at both ends of the sliding direction of the sliding cover 2 is the end inner side wall, and the drinking opening 4 is arranged on the groove bottom surface 8 of the sliding groove 7 close to one of the end inner side walls, which is a specific end inner side wall 18. The part of the outer side wall of the sliding cover 2 located at both ends of the sliding direction of the sliding cover 2 is the end outer side wall, and the end outer side wall facing the specific end inner side wall 18 is a specific end outer side wall 19.

[0073] The second guiding and pressing assembly is arranged between the specific end inner side wall 18 and the specific end outer side wall 19, and the second guiding and pressing assembly comprises a clamping groove 20 and a clamping block 21, either of which is arranged on the specific end inner side wall 18, and the other is arranged on the specific end outer side wall 19. During the sliding of the sliding cover 2 from the open position to the closed position, the clamping block 21 is inserted into the clamping groove 20; and the clamping block 21 and the clamping groove 20 are configured such that, during the insertion of the clamping block 21 into the clamping groove 20, the clamping block 21 / clamping groove 20 arranged on the specific end outer side wall 19 moves to the second side of the cover body 1 under the limitation of the clamping groove 20 / clamping block 21 arranged on the specific end inner side wall 18.

[0074] Specifically, in the embodiment, the clamping groove 20 is arranged on the side wall of the sliding groove 7, and the clamping block 21 is arranged on the end of the sliding cover 2. In the second guiding and pressing assembly, the inner wall surface of the clamping groove 20 facing the second side of the cover body 1 is the guiding surface, and the outer surface of the clamping block 21 facing the first side of the cover body 1 is the guiding surface.

[0075] The arrangement of the second guiding and pressing assembly can not only provide guiding and pressing effect in the second stroke of the sliding cover 2, but also can play a fixing role. When the sliding cover 2 is in the closed position, the second guiding and pressing assembly fixes the end of the sliding cover 2 (specifically, the end corresponding to the drinking opening 4). For example, when the content is hot water, hot gas is easy to push the elastic sealing member 3 away from the end of the sliding cover 2 through the drinking opening 4, thereby damaging the seal and causing leakage. The arrangement of the second guiding and pressing assembly between the outer side wall 19 of the specific end of the sliding cover 2 and the inner side wall 18 of the specific end of the cover body 1 can effectively prevent such leakage.

[0076] In order for the anti-disengagement unit to play a guiding and pressing role, the clamping block 23 and the clamping groove are configured such that, during the extension of the clamping block 23 into the clamping groove, the clamping block 23 moves to the second side of the cover body 1 under the limitation of the inner side wall of the clamping groove facing the second side of the cover body 1. In the anti-disengagement unit, the inner wall surface of the clamping groove facing the second side of the cover body 1 is the guiding surface, and the outer surface of the clamping block 23 facing the first side of the cover body 1 is the guiding surface.

[0077] Therefore, the anti-disengagement unit in the embodiment can not only prevent the sliding cover 2 from disengaging from the cover body 1 when the sliding cover 2 is in the closed position, but also can provide guiding and pressing effect in the second stroke of the sliding cover 2.

[0078] The sliding cover 2 and the cover body 1 are assembled together, and the user can replace one of them at will, for example, when one of them is damaged, the damaged one is replaced, and for example, the sliding cover 2 may sometimes be lost (the cover body 1 is connected to the container and is relatively large in size, and is not easy to lose compared to the sliding cover 2) and needs to be replaced. In order to facilitate the user to assemble the sliding cover 2 and the cover body 1, the sliding cover 2 can be designed as a central symmetric structure, so that the user does not need to distinguish the two ends of the sliding cover 2 in the sliding direction when installing the sliding cover 2, which is convenient for the user to install. The sliding cover 2 is a central symmetric structure, and the guiding groove 16, the clamping block 21, the clamping block 23, the elastic sealing member 3 and the like on the sliding cover 2 need to be arranged centrally symmetrically.

[0079] Although the sliding cover 2 presses the elastic seal 3 against the cover body 1 when in the closed position, if the sliding cover 2 presses the elastic seal 3 against the cover body 1 throughout the sliding process of the sliding cover 2, the frictional resistance will be increased, which will affect the user's hand feeling. Therefore, the embodiment is further provided with a lifting structure, which is arranged between the cover body 1 and the sliding cover 2, and is used to guide the sliding cover 2 to move towards the first side of the cover body 1 during the process of the sliding cover 2 sliding away from the closed position, so that the sliding cover 2 relaxes the pressing of the elastic seal 3. Preferably, in the direction perpendicular to the groove bottom surface 8 of the sliding groove 7, the distance that the sliding cover 2 moves away from the closed position under the action of the lifting structure is greater than the distance that the elastic seal 3 protrudes from the sliding cover 2, so that the elastic seal 3 is not in contact with the groove bottom surface 8 of the sliding groove 7 after the sliding cover 2 moves away from the closed position, thereby reducing the sliding frictional resistance of the sliding cover 2 in the sliding groove 7.

[0080] For the convenience of description, the stroke of the sliding cover 2 sliding from the closed position to the open position is referred to as the third stroke, and the stroke of the sliding cover 2 moving towards the first side of the cover body 1 relative to the cover body 1 in the guidance of the lifting structure is referred to as the fourth stroke. The fourth stroke is a part of the third stroke and is located at the beginning end of the third stroke.

[0081] The lifting structure comprises at least one lifting assembly, and the lifting assembly comprises a lifting protrusion 24 and a corresponding groove 25. Any one of the lifting protrusion 24 and the groove 25 is arranged on the surface of the sliding cover 2 facing the cover body 1, and the other one is arranged on the surface of the cover body 1 facing the sliding cover 2. When the sliding cover 2 is in the closed position, the lifting protrusion 24 is located in the groove 25, and when the sliding cover 2 slides away from the closed position, the lifting protrusion 24 moves away from the groove 25 to make the sliding cover 2 move towards the first side of the cover body 1 relative to the cover body 1. Further, the groove 25 is correspondingly provided with a sliding groove 26, one end of the sliding groove 26 communicates with the groove 25; when the sliding cover 2 slides on the cover body 1, the lifting protrusion 24 slides in the sliding groove 26, and when the sliding cover 2 slides to the closed position, the lifting protrusion 24 slides to the groove 25. The arrangement of the sliding groove 26 can guide the movement of the lifting protrusion 24.

[0082] Specifically in the embodiment, the lifting protrusion 24 is arranged on the sliding cover 2, and the groove 25 and the sliding groove 26 are arranged on the groove bottom surface 8 of the sliding groove 7; four lifting assemblies are arranged in the cover assembly, two lifting assemblies arranged in the direction perpendicular to the first direction form a group, and the two groups of lifting assemblies are arranged along the first direction.

[0083] The region in which the sliding cover 2 slides in the sliding groove 7 in the second stroke is the same as the region in which the sliding cover 2 slides in the sliding groove 7 in the fourth stroke, and the sliding direction of the sliding cover 2 in the second stroke is opposite to the sliding direction of the sliding cover 2 in the fourth stroke.

[0084] The elastic sealing member 3 comprises a first sealing part 27, which is arranged on the side of the sliding cover 2 facing the cover body 1. When the sliding cover 2 is in the closed position, the first sealing part 27 covers the drinking opening 4 and extends to the periphery of the drinking opening 4 on the groove bottom surface 8 of the sliding groove 7. In this way, when the sliding cover 2 presses the elastic sealing member 3 against the groove bottom surface 8 of the sliding groove 7, the elastic sealing member 3 can seal the drinking opening 4. However, the sealing performance of this sealing method is poor. Therefore, in this embodiment, the elastic sealing member 3 is further improved, and the elastic sealing member 3 further comprises a second sealing part 28.

[0085] As shown in Figure 10 , the second sealing part 28 has a ring structure and is arranged on the side of the first sealing part 27 facing the groove bottom surface 8 of the sliding groove 7; when the sliding cover 2 is in the closed position, the drinking opening 4 is located inside the ring structure of the second sealing part 28. Preferably, the elastic sealing member 3 can comprise multiple layers of second sealing parts 28, and the ring structures of the multiple layers of second sealing parts 28 are arranged in sequence, thereby improving the sealing effect.

[0086] Further, the first sealing part 27 extends away from the cover body 1 through the channel on the sliding cover 2 and extends to the surface of the side of the sliding cover 2 away from the cover body 1, and the size of the member formed by the first sealing part 27 on the surface of the side of the sliding cover 2 away from the cover body 1 is greater than the channel on the sliding cover 2. The member can be used as an anti-slip strip 30 when a user pushes the sliding cover 2. In addition to being able to prevent slipping, the anti-slip strip 30 can also prevent the first sealing part 27 from being separated from the sliding cover 2. Preferably, the first sealing part 27 can form multiple anti-slip strips 30 through multiple channels on the sliding cover 2.

[0087] A gas hole 31 can be arranged on the groove bottom surface 8 of the sliding groove 7 to communicate the first side and the second side of the cover body 1, a gas channel 32 corresponding to the gas hole 31 is arranged on the surface of the sliding cover 2 facing the groove bottom surface 8 of the sliding groove 7, and a gas hole sealing member corresponding to the gas hole 31 is arranged on the sliding cover 2. When the sliding cover 2 is in the closed position, the gas hole sealing member seals the gas hole 31; when the sliding cover 2 is in the open position, the gas hole sealing member is away from the gas hole 31, the gas hole 31 communicates with the gas channel 32, and the container can communicate with the outside through the gas hole 31 and the gas channel 32 in addition to the drinking opening 4.

[0088] Specifically, in this embodiment, the gas hole sealing member can be a third sealing part 29 protruding from the first sealing part 27, and the third sealing part 29 is arranged on the side of the first sealing part 27 facing the groove bottom surface 8 of the sliding groove 7; the third sealing part 29 has a ring structure. At this time, the third sealing part 29 is part of the elastic sealing member 3, and the gas hole sealing member is part of the elastic sealing member 3. Preferably, the third sealing part 29 can also be arranged in multiple layers, and the ring structures of the multiple layers of third sealing parts 29 are arranged in sequence, thereby improving the sealing effect.

[0089] The slide cover 2 is a center-symmetrical structure, and two elastic sealing members 3 are arranged on the slide cover 2. When the slide cover 2 is in the closed position, the drinking opening 4 is located inside the annular structure of the second sealing part 28 in one of the elastic sealing members 3, and the air hole 31 is located inside the annular structure of the corresponding third sealing part 29 in the other elastic sealing member 3. In this way, when the slide cover 2 is in the closed position, the two elastic sealing members 3 seal the drinking opening 4 and the air hole 31 respectively.

[0090] Preferably, the whole elastic sealing member 3 is integrally formed, and the elastic sealing member 3 is made of silica gel or rubber.

[0091] Of course, in other embodiments, the elastic sealing member 3 and the air hole sealing member can also adopt other structures. For example, in an embodiment in which the elastic sealing member 3 is only provided with the first sealing part 27 (without the second sealing part 28), the center-symmetrical part of the elastic sealing member 3 can be used as the air hole sealing member.

[0092] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments. Even if various changes are made to the utility model, as long as the changes belong to the scope of the utility model claims and equivalent technologies, they still fall within the protection scope of the utility model.
