Description

TECHNICAL FIELD

[0001] The utility model belongs to cup cover technical field, especially relate to a sealing structure of cover subassembly. 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. The driver can directly drink the water in the cup. However, the dust inside the car can easily fall into the cup through the opening, causing the water in the cup to mix with the 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 slide 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, patent US10124942B2 provides a cover assembly that can be used on a car cup. Specifically, a first opening (through which the driver drinks the liquid in the cup) is provided on the cover body, a sliding block is slidably arranged on the cover body, a first positioning magnet is provided on the sliding block, and a second positioning magnet and a third positioning magnet are provided on the cover body. When the sliding block is slid to a position where the first positioning magnet and the second positioning magnet are attracted to each other, the sliding block is kept in the closed position under the action of the magnetic force. When the sliding block is in the closed position, it covers the first opening, so that the liquid in the cup will not flow out of the first opening. When the sliding block is slid to a position where the first positioning magnet and the third positioning magnet are attracted to each other, the sliding block is kept in the open position under the action of the magnetic force. At this time, the sliding block does not cover the first opening, and the first opening is exposed, so that the driver can drink the liquid in the cup through the first opening.

[0005] For example, patent CN217565584U provides a resilient opening and closing cup cover that can be used on a car cup. A sliding groove is provided on the cover body, one end of the sliding groove is provided with a drinking opening, and a sliding cover is slidably arranged in the sliding groove. A closing positioning groove and an opening positioning groove are sequentially provided on the side wall of the sliding groove, and a resilient wall is protrudingly provided on one side of the sliding cover. When the sliding cover is slid to a position where the resilient arm is arranged in the closing positioning groove, the sliding cover covers the drinking opening so that the liquid in the cup will not flow out of the drinking opening. When the sliding cover is slid to a position where the resilient arm is in the opening positioning groove, the sliding cover does not cover the drinking opening, and the drinking opening is exposed, so that the driver can drink the liquid in the cup through the drinking opening.

[0006] The two cup covers 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.

[0007] However, over time, more and more people began 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 life product. The continuous expansion of the use of car cups has prompted users to have higher and more diversified demands for its functions.

[0008] When the car cup is used in daily life instead of being placed in the car cup holder in the car, the car cup is knocked down more and more frequently. How to ensure that the liquid in the cup does not spill when the car cup is knocked down has become a new design requirement and innovation direction. Utility model content

DETAILED DESCRIPTION

[0040] ​​In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, specific implementation manners of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative effort, and other embodiments can also be obtained.

[0041] For the sake of simplicity of the drawings, only parts related to the present application are schematically shown in the drawings, which do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this document, "one" not only means "only one", but also means "more than one" situation.

[0042] Referring to Figures 1 to 14 The present embodiment provides a sealing structure of a cover assembly, which comprises a cover body 1, a sliding cover 2 and an elastic sealing member 3. The cover body 1 is provided with a drinking opening 4, and the sliding cover 2 is slidably arranged on the cover body 1 and is configured to be slidable between a closed position and an open position on the cover body 1. The elastic sealing member 3 is arranged on the sliding cover 2, and the sliding cover 2 drives the elastic sealing member 3 to move when sliding. 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 at the same time, an air hole 31 on the cover body 1 is in a ventilation state.

[0043] For the sake of description, the combination of the cover body 1, the sliding cover 2 and the elastic sealing member 3 is referred to as a cover assembly. The cover assembly is generally used in cooperation with a containing member. The cover body 1 in the cover assembly is threadedly connected or coveringly connected to the opening of the containing member, forming a container (in addition to the cover assembly and the containing member, other components can also be added according to actual needs). For example, the containing member can be a cup body, a bottle body, etc., and the cover assembly is connected to the cup opening of the cup body or the bottle opening of the bottle body to form a cup or a bottle with a cover. The content in the containing member can be taken out from the drinking opening 4 on the cover body 1.

[0044] When using the container, if the user needs to pour out the contents (e.g., if the contents are water and they want to drink it), they can slide the sliding cover 2 on the lid body 1 to the open position, allowing the user to pour out the contents from the drinking spout 4. When the user does not need to pour out the contents (e.g., if they do not want to drink), they can slide the sliding cover 2 to the closed position. In this state, the sliding cover 2 covers the drinking spout on the lid body 1, and the elastic sealing element 3 covers the drinking spout. The sliding cover 2 presses the elastic sealing element 3 against the drinking spout, thus sealing the drinking spout and preventing the contents from pouring out or flowing out of the drinking spout 4 when the container is tilted. It should be noted that although the container is commonly used to hold liquids such as drinking water, it can also be used to hold solid particles, and there are no restrictions on the type of contents.

[0045] Among them, such as Figure 2 As shown, when the lid body 1 is placed on a horizontal surface, the upper side of the lid body 1 is the first side of the lid body 1, and the lower side of the lid body 1 is the second side of the lid body 1. The upward direction is the direction of the first side of the lid body 1, and the downward direction is the direction of the second side of the lid body 1. The drinking spout 4 is a through hole connecting the first side and the second side of the lid body 1, and the sliding cover 2 is slidably mounted on the first side of the lid body 1.

[0046] The resilient seal 3 includes a first sealing portion 27, which covers 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 portion 27 covers the drinking spout 4, and the portion covered by the first sealing portion 27 extends from the drinking spout 4 to the periphery of the drinking spout 4 on the cover body. Thus, when the sliding cover 2 presses the resilient seal 3 against the cover body 1, the resilient seal 3 can seal the drinking spout 4. However, this sealing method has poor sealing performance. Therefore, in this embodiment, the resilient seal 3 is further improved by including a second sealing portion 28.

[0047] like Figure 10 As shown, the second sealing part 28 is an annular structure and protrudes from the first sealing part 27 on the side facing the cover body 1; when the sliding cover 2 is in the closed position, the drinking spout 4 is located inside the annular structure of the second sealing part 28. Preferably, the elastic sealing element 3 may include multiple layers of the second sealing part 28, with the annular structures of the multiple layers of the second sealing part 28 nested sequentially, thereby improving the sealing effect.

[0048] Further, the first sealing part 27 extends to the surface of the side of the sliding cover 2 away from the cover body 1 through the channel on the sliding cover 2, and the size of the member formed on the surface of the side of the sliding cover 2 away from the cover body 1 is larger than the channel on the sliding cover 2. The member can be used as an anti-skid strip 30 when the user pushes the sliding cover 2. In addition to the anti-skid function, the anti-skid 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-skid strips 30 through multiple channels on the sliding cover 2.

[0049] A gas hole 31 can be arranged on the cover body 1 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 cover body 1, 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, the gas hole 31 is opened, and in addition to the container interior being able to communicate with the outside through the drinking opening 4, the container interior is also able to communicate with the outside through the gas hole 31 and the gas channel 32.

[0050] Specifically, in the embodiment, the gas hole sealing member can be a third sealing part 29 protruding on the first sealing part 27, the third sealing part 29 is arranged on the side of the first sealing part 27 facing the cover body 1; the third sealing part 29 is in 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 the third sealing part 29 are sequentially sleeved, thereby improving the sealing effect.

[0051] The sliding cover 2 is in a central symmetry structure, and two elastic sealing members 3 are arranged on the sliding cover 2. 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 in one of the elastic sealing members 3, and the gas hole 31 is located inside the ring structure of the corresponding third sealing part 29 in the other elastic sealing member 3. In this way, when the sliding cover 2 is in the closed position, the two elastic sealing members 3 seal the drinking opening 4 and the gas hole 31, respectively.

[0052] Preferably, the entire elastic sealing member 3 is integrally made, and the elastic sealing member 3 is made of silica gel or rubber.

[0053] Of course, in other embodiments, the elastic sealing member 3 and the gas hole sealing member can also adopt other structures, for example, in the embodiment in which the elastic sealing member 3 is only provided with the first sealing part 27 (without the second sealing part 28), the part of the elastic sealing member 3 after being centrally symmetrical can be used as the gas hole sealing member.

[0054] The connection between the sliding cover 2 and the cover body 1 can be magnetically detachable, and specifically can beFigure 14 As mentioned above, a first magnet 5 is provided on the sliding cover 2, and a second magnet 6 is provided on the cover body 1. The first magnet 5 and the second magnet 6 attract each other, thereby attracting the sliding cover 2 to the cover body 1.

[0055] When the sliding cover 2 is in the closed position, it presses the elastic seal 3 against the drinking spout 4 on the cover body 1. The sliding cover 2 tightens the elastic seal 3 (and the elastic seal 3 needs to undergo elastic deformation), thus sealing the drinking spout 4. There are several ways to ensure that the sliding cover 2 can tighten the elastic seal 3 against the drinking spout 4 on the cover body 1 when in the closed position. For example, it can use a first magnet 5 and a second magnet 6 with sufficiently strong magnetic attraction. This method does not require other structural modifications to the cover assembly (such as...). Figure 16 and Figure 17 The cover body 1 shown does not have the guide pressing structure described below. It can be made simply by replacing the first magnet 5 and the second magnet 6, which can generate a stronger magnetic force. This is a manufacturing-friendly solution, but it also has other disadvantages—the first magnet 5 and the second magnet 6, which have a stronger magnetic force, are themselves more expensive. In this embodiment, the guide pressing structure is used so that the sliding cover 2 presses the elastic seal 3 against the drinking spout 4 of the cover body 1 when it is in the closed position.

[0056] Specifically, the guide pressing structure can guide the part of the sliding cover 2 with the elastic sealing element 3 to move towards the second side of the cover body 1 during the process of sliding the cover 2 to the closed position, so that when the sliding cover 2 is in the closed position, the elastic sealing element 3 can be pressed tightly onto the cover body 1, thereby achieving the sealing of the drinking spout 4 by the elastic sealing element 3.

[0057] For ease of description, the stroke of the sliding cover 2 from the open position to the closed position is called the first stroke, and the stroke of the sliding cover 2 to the closed position under the guidance of the guide pressing structure is called the second stroke. The sliding direction of the sliding cover 2 in the first stroke 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.

[0058] 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 pressing structure includes at least one guide pressing assembly, which includes a first guide portion and a second guide portion. The first guide portion is disposed on the cover body 1, and the second guide portion is disposed on the sliding cover 2 and moves synchronously with the sliding cover 2. During the second stroke, the first guide portion and the second guide portion are slidably connected, and the second guide portion is located in the direction of the first guide portion toward the second side of the cover body 1. The first guide portion and the second guide portion are configured such that, during the second stroke, the second guide portion moves toward the second side of the cover body 1 when it slides under the constraint 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 a guide surface, the first guide portion is a guide surface arranged towards the second side of the cover body 1; when the second guide portion is a guide surface, the second guide portion is a guide surface arranged towards the first side of the cover body 1. The guide surface is offset towards the second side of the cover body 1 in the first direction, 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), 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 a guide surface, in the second stroke, the second guide portion moves synchronously with the sliding cover 2, and the second guide portion slides against the guide surface (i.e. the first guide portion) when the sliding cover 2 slides in the first direction. Since the guide surface is offset towards the second side of the cover body 1 in the first direction, the second guide portion will gradually move towards the second side of the cover body 1 under the restriction of the guide surface, thereby driving the sliding cover 2 to move towards the second side of the cover body 1.

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

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

[0064] The cover body 1 has a mounting surface 8 facing the first side direction thereof, the drinking opening 4 is arranged on the mounting surface 8, and the sliding cover 2 slides on the mounting surface 8. In the second stroke, in the direction perpendicular to the mounting surface 8, the moving distance of the portion of the sliding cover 2 on which the elastic sealing member 3 is arranged is less than the distance by which the elastic sealing member 3 protrudes from the sliding cover 2, so that the sliding cover 2 can press the elastic sealing member 3 against the drinking opening 4 of the cover body 1 in the closed position and press the elastic sealing member 3 to be elastically deformed, thereby closing the drinking opening 4. The distance by which the elastic sealing member 3 protrudes from the sliding cover 2 is small, so that the moving distance of the portion of the sliding cover 2 on which the elastic sealing member 3 is arranged in the second stroke in the direction perpendicular to the mounting surface 8 is also small, which is generally selected to be within 5 mm, and preferably about 0.6 mm; of course, the specific distance by which the portion of the sliding cover 2 on which the elastic sealing member 3 is arranged moves in the second stroke in the direction perpendicular to the mounting surface 8 also needs 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 that the moving distance of the portion of the sliding cover 2 on which the elastic sealing member 3 is arranged in the second stroke in the plane parallel to the mounting surface 8 is also small, which is generally selected to be within 10 mm, and preferably about 2 mm.

[0066] In this way, the arrangement of the lead wire pressing structure does not affect the hand feeling of the user in the process of pushing the sliding cover 2.

[0067] 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 is the mounting surface 8 described above, and the groove bottom surface 8 of the sliding groove 7 is provided with the drinking opening 4 described above; 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 the closed positioning groove 9 and the open positioning groove 10, and both sides of the sliding cover 2 are provided with the 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 two side walls of the sliding groove 7 are also symmetrically arranged.

[0068] As Figure 7As shown, 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 are both provided with the gap 13 between the side wall of the sliding cover 2, and the gap 13 is used for the 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 to 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.

[0069] Wherein, the part of the inner side wall of the sliding groove 7 located at both sides in the sliding direction of the sliding cover 2 is the sliding inner side wall 14, and the closed positioning groove 9 and the open positioning groove 10 are arranged in the sliding inner side wall 14; the part of the outer side wall of the sliding cover 2 located at both sides in the sliding direction of the sliding cover 2 is the sliding outer side wall 15.

[0070] The guide and pressing structure in the embodiment includes a first guide and pressing assembly, a second guide and pressing assembly and a third guide and pressing assembly, wherein the first guide and pressing assembly plays a main guide and pressing role (the guide and pressing role is the role of moving the sliding cover 2 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 assembly in the process of sliding from the open position to the closed position.

[0071] The first guide and pressing assembly includes the guide groove 16 and the guide protrusion 17, and any one of the guide groove 16 and the guide protrusion 17 is arranged in the sliding inner side wall 14, and the other is arranged in the sliding outer side wall 15. In the stroke of the sliding cover 2 sliding from the open position to the closed position, at least part of the stroke is connected with the guide groove 16 in the sliding connection of the guide protrusion 17; specifically, the guide protrusion 17 is connected with the guide groove 16 in the sliding connection in the second stroke. The guide groove 16 is offset to the second side of the cover body 1 in the first direction.

[0072] Specifically in the embodiment, the two sliding inner side walls 14 of the sliding groove 7 are respectively provided with a first guide and pressing assembly in cooperation with the corresponding sliding outer side wall 15. Moreover, when the sliding cover 2 is in the closed position, there is a first guide and pressing assembly on each side of the drinking opening 4 in the first direction. Thus, when the sliding cover 2 is in the closed position, the first guide and pressing assemblies on both sides of the drinking opening 4 can well exert force on the sliding cover 2, so that the sliding cover 2 presses the elastic sealing member 3 tightly at the drinking opening 4, so that the elastic sealing member 3 seals the drinking opening 4 and prevents the contents in the container from flowing out. In the first guide and pressing assembly, the inner side wall of the guide groove 16 on the sliding cover 2 close to the second side of the cover body 1 (i.e., the inner side wall of the guide groove 16 facing the first side of the cover body 1, the inner side wall of the guide groove 16 on the second side of the cover body 1 in the direction of the guide protrusion 17) is the guide surface.

[0073] The end of the guide groove 16 in the first direction can be provided with an opening, and the opening is used for the guide protrusion 17 to slide into the guide groove 16 from the opening during the sliding of the sliding cover 2 in the first direction.

[0074] The portions of the inner side walls of the sliding groove 7 located at both ends of the sliding direction of the sliding cover 2 are end inner side walls, 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 portions of the outer side walls of the sliding cover 2 located at both ends of the sliding direction of the sliding cover 2 are end outer side walls, and the end outer side wall facing the specific end inner side wall 18 is a specific end outer side wall 19.

[0075] The second guide and pressing assembly is arranged between the specific end inner side wall 18 and the specific end outer side wall 19, and the second guide and pressing assembly includes a clamping groove 20 and a clamping block 21. Either the clamping groove 20 or the clamping block 21 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. Moreover, 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 in the direction of 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.

[0076] 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 guide and pressing assembly, the inner wall surface of the clamping groove 20 facing the second side of the cover body 1 is the guide surface, and the outer surface of the clamping block 21 facing the first side of the cover body 1 is the guide surface.

[0077] The second guide-pressing component not only provides a guiding and pressing effect during the second stroke of the sliding cover 2, but also serves a fixing function—when the sliding cover 2 is in the closed position, the second guide-pressing component fixes the end of the sliding cover 2 (specifically, the end corresponding to the drinking spout 4). For example, when the contents are hot water, hot air can easily push open the elastic seal 3 from the end of the sliding cover 2 through the drinking spout 4, thereby breaking the seal and causing leakage. The second guide-pressing component, located between the outer wall 19 of a specific end of the sliding cover 2 and the inner wall 18 of a specific end of the cover body 1, can effectively prevent such leakage.

[0078] The third guide pressing assembly includes a locking member 22 protruding from the bottom surface 8 of the sliding groove 7 and a locking block 23 disposed on the sliding cover 2. The locking member 22 protrudes a certain distance from the bottom surface 8 towards the first side of the cover body 1 and then bends in the second direction, so that the locking member 22 and the bottom surface 8 cooperate to form a locking groove facing the second direction. During the process of the sliding cover 2 sliding from the open position to the closed position, the locking block 23 extends into the locking groove; and the locking block 23 and the locking groove are configured such that, during the process of the locking block 23 extending into the locking groove, the locking block 23 moves towards the second side of the cover body 1 under the constraint of the inner sidewall of the locking groove facing the second side of the cover body 1. In the third guide pressing assembly, the inner wall surface of the locking groove facing the second side of the cover body 1 is the aforementioned guide surface, and the outer surface of the locking block 23 facing the first side of the cover body 1 is the aforementioned guide surface.

[0079] like Figure 12 As shown, the engaging block 23 can be disposed at the connection between the connecting arm 12 and the sliding cover 2. The engaging member 22 can protrude from the bottom surface 8 of the groove and extend into the gap 13, that is, the engaging member 22 is disposed in the gap 13. Preferably, two third guide pressing components can be disposed between the cover body 1 and the sliding cover 2, and two engaging members 22 are disposed on the bottom surface 8 of the sliding groove 7.

[0080] The third guide pressing component, in addition to providing a guiding pressing effect during the second stroke of the sliding cover 2, also serves to prevent detachment. When a container with the cover assembly is dropped from a height (e.g., when a user accidentally bumps the container while holding it, or when the container falls from a table after being bumped), the third guide pressing component effectively prevents the sliding cover 2 from detaching from the cover body 1. If the sliding cover 2 does detach from the cover body 1, its small size makes it easy to lose.

[0081] The slide 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 another example, the slide cover 2 can be lost sometimes (the cover body 1 is connected to the containing member and is large in size, and is not easy to lose compared with the slide cover 2) and needs to be replaced. In order to facilitate the user to assemble the slide cover 2 and the cover body 1, the slide cover 2 can be designed as a central symmetric structure, so that the user does not need to distinguish the two ends of the slide cover 2 in the sliding direction when installing the slide cover 2, and the user is facilitated to install. The slide cover 2 is a central symmetric structure, and the guide groove 16, the clamping block 21, the clamping block 23, the elastic sealing member 3 and the like on the slide cover 2 need to be centrally symmetrically arranged.

[0082] The first guide and pressing assembly, the second guide and pressing assembly and the third guide and pressing assembly all have the guide and pressing function, and therefore in other embodiments, only any one or any two of them can be arranged, and in other embodiments, the guide and pressing structure specifically includes several guide and pressing assemblies (the first guide and pressing assembly, the second guide and pressing assembly and the third guide and pressing assembly), and which several guide and pressing assemblies are included can be set according to actual conditions, for example Figure 15 The cover assembly corresponding to the cover body 1 shown in FIG. 8 only includes the first guide and pressing assembly and the second guide and pressing assembly.

[0083] Although the slide cover 2 presses the elastic sealing member 3 against the cover body 1 when the slide cover 2 is in the closed position, if the slide cover 2 tightly presses the elastic sealing member 3 against the cover body 1 during the entire sliding process of the slide cover 2, a lot of frictional resistance will be increased, which affects the hand feeling of the user. Therefore, the lifting structure is further arranged between the cover body 1 and the slide cover 2 in the embodiment, the lifting structure is used to guide the slide cover 2 to move to the first side direction of the cover body 1 during the process that the slide cover 2 slides away from the closed position, so that the slide cover 2 relaxes the pressing of the elastic sealing member 3. Preferably, in the direction perpendicular to the groove bottom surface 8 of the sliding groove 7, the distance that the slide cover 2 moves away from the closed position under the action of the lifting structure is greater than the distance that the elastic sealing member 3 protrudes from the slide cover 2, so that after the slide cover 2 moves away from the closed position, the elastic sealing member 3 does not contact the groove bottom surface 8 of the sliding groove 7, thereby reducing the sliding frictional resistance of the slide cover 2 in the sliding groove 7.

[0084] For the convenience of description, the stroke of the slide cover 2 from the closed position to the open position is referred to as a third stroke, and the stroke of the slide cover 2 moving to the first side direction of the cover body 1 relative to the cover body 1 in the guidance of the lifting structure is referred to as a fourth stroke. The fourth stroke is a part of the third stroke and is located at the first end of the third stroke.

[0085] 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 cover body 1 facing the sliding cover 2, and the other one is arranged on the surface of the sliding cover 2 facing the cover body 1. 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 out of the groove 25 to move the sliding cover 2 relative to the cover body 1 to the first side of the cover body 1. Further, the groove 25 is provided with a sliding groove 26 corresponding to the groove 25, 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.

[0086] 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 in the first direction.

[0087] The second stroke is the same as the fourth stroke in the area of the sliding cover 2 sliding in the sliding groove 7, 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.

[0088] The above describes the embodiments of the utility model in detail 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, if 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.
