Cup cover

Abstract

According to the cup cover, the sliding block is located at one end of the sliding groove, at the moment, the communication opening is shielded by the sliding block, the inner space of a container is isolated from the outer space, and liquid is not prone to flowing out. When a user needs to drink, the sliding block is pushed to start to slide in the length direction of the sliding groove. The communicating port is opened until the other end of the sliding groove is reached, the inner space of the container is communicated with the outer space, and liquid can flow out. After a user finishes using, the sliding block slides back to the initial position in the opposite direction under manual operation, the communication opening is shielded again, sealing is achieved, and due to the fact that the magnetism of the side, close to the second magnetic piece, of the first magnetic piece is opposite to that of the second magnetic piece, the sliding block can firmly seal the communication opening through the first magnetic piece and the second magnetic piece; and liquid in the internal space of the container is prevented from flowing out through the communication port. Due to the fact that the magnetism of the first magnetic piece is opposite to that of the second magnetic piece, reverse thrust is generated when the second magnetic piece slides through the middle point of the first magnetic piece, and the cup cover is opened and closed very smoothly.

Description

Technical Field

[0001] This application relates to the field of cup lids, and particularly to a cup lid. Background Art

[0002] A cup lid refers to a lid used to cover the cup mouth, and is commonly used for various types of cups, such as coffee cups, tea cups, thermos cups, etc. The main functions of the cup lid are to prevent beverage spillage, keep warm, and prevent dust.

[0003] Traditional tea cup lids are usually made of ceramic or glass, and sometimes are equipped with a filter for easy tea brewing. However, traditional cup lids usually adopt a screwing-open method for opening and closing, which is very inconvenient in occasions where frequent drinking is required. For the convenience of use, some existing cup lids adopt an opening and closing type lid, and are opened and closed through spring damping, silicone damping, plastic damping, etc., so as to facilitate opening and closing. For example, a thermos cup lid structure in CN217959586U. When in use, the upper lid is pushed by hand to rotate and close the water outlet. The upper lid can push open the hook through the contact and relative movement of the wedge surface and the guiding inclined surface, and push the locking key to rotate against the resistance of the return spring. The return spring is compressed until the upper lid rotates and closes in place. After releasing the hand, the return spring extends to push the locking key to rotate back to its original position, and the hook at the upper end of the locking key extends into the hook groove to lock the upper lid, realizing automatic locking during the rotation and closing process of the upper lid, so as to achieve easy opening and closing of the cup lid for easy drinking and sealing.

[0004] However, when using spring damping, silicone damping, plastic damping, etc. to open and close the cup lid, over time, the spring damping, silicone damping, or plastic damping is prone to aging, wear, etc., resulting in abnormal opening and closing.

[0005] Secondly, it affects the sealing performance. Once hot water is filled, due to poor sealing performance, hot water will leak out, resulting in scalding and other situations, which is not convenient for use. Summary of the Utility Model

[0006] In view of this, it is necessary to provide a cup lid to solve the above problems.

[0007] An embodiment of this application provides a cup lid, including:

[0008] A lid body, provided with a chute and a communication port communicating with the chute, and the communication port is used to communicate the internal space of the container with the external space;

[0009] A slider, slidably arranged in the chute;

[0010] A first magnetic member, arranged in the chute;

[0011] A second magnetic member, arranged on the slider, and the side of the first magnetic member close to the second magnetic member is arranged with opposite magnetism to the second magnetic member;

[0012] Wherein, the first magnetic member and the second magnetic member repel each other, so that the slider slides along the chute to block the communication port, so that the cover body seals the internal space of the container.

[0013] In at least one embodiment of the present application, the cover body has a receiving surface, and a positioning groove is formed on the receiving surface;

[0014] The cup cover further includes:

[0015] A capsule rotor, which is movably received in the positioning groove and attracted to the first magnetic member to adsorb the capsule rotor in the positioning groove.

[0016] In at least one embodiment of the present application, the cover body has a shielding surface facing away from the receiving surface. The shielding surface is provided with a first sliding groove and a second sliding groove, both of which communicate with the chute. Both sides of the slider penetrate through the chute and extend into the first sliding groove and the second sliding groove respectively.

[0017] In at least one embodiment of the present application, an installation portion protrudes from the receiving surface;

[0018] The cup cover further has a sealing ring disposed around the outer peripheral surface of the installation portion.

[0019] In at least one embodiment of the present application, both ends of the chute have a first position and a second position, and the communication port is provided at the first position;

[0020] Wherein, slide the slider so that the slider slides from the first position to the second position along the length direction of the chute, so that the internal space of the container communicates with the outside through the communication port. Slide the slider in the reverse direction, and the first magnetic member and the second magnetic member repel each other, so that the slider completely blocks the communication port along the direction perpendicular to the shielding surface to seal the internal space of the container.

[0021] In at least one embodiment of the present application, a first limiting portion protrudes from the inner wall of the chute toward the side close to the slider, and the first limiting portion is disposed close to the first position;

[0022] A second limiting portion is provided on the side of the slider close to the first limiting portion. An activity space is formed in the area from the first limiting portion to the second position, and the second limiting portion is located in the activity space;

[0023] Wherein, when the slider is located at the first position, the second limiting portion abuts against the first limiting portion to limit the slider from continuing to move in the chute in the direction close to the first position; slide the slider along the direction close to the second position, so that the second limiting portion slides in the movable space, so that the internal space of the container is communicated with the outside through the communication port.

[0024] In at least one embodiment of the present application, a first installation groove is provided in the chute, the first magnetic member is fixed in the first installation groove, and the first installation groove is communicated with the movable space.

[0025] In at least one embodiment of the present application, a second installation groove is provided on one side of the slider close to the receiving surface, and the second magnetic member is fixed in the second installation groove.

[0026] In at least one embodiment of the present application, the slider has a shielding end, the distance from the second magnetic member to the shielding end is denoted as a, the length of the chute is denoted as b, and the maximum distance from the first magnetic member to the first position is denoted as c, satisfying the relational expression: a < c < b.

[0027] In at least one embodiment of the present application, the slider has a pushing end arranged opposite to the shielding end, the distance from the second magnetic member to the pushing end is denoted as d, and the maximum distance from the first magnetic member to the second position is denoted as e, satisfying the relational expression: d < e;

[0028] Wherein, at the first position and the second position of the slider, the first magnetic member and the second magnetic member repel each other.

[0029] Implementing the cup lid of this embodiment will at least have the following beneficial effects:

[0030] For the cup lid provided above, the slider is located at one end of the chute. At this time, the communication port is blocked by the slider, and the internal space of the container is isolated from the external space, and the liquid is not easy to flow out.

[0031] When the user needs to drink, push the slider to make the slider start to slide along the length direction of the chute.

[0032] Until the other end of the chute, the communication port is opened, the internal space of the container is communicated with the external space, and the liquid can flow out.

[0033] After the user finishes using it, the slider slides back to the initial position in the opposite direction under manual operation, blocking the communication port again to achieve sealing. Since the side of the first magnetic member close to the second magnetic member is arranged with the opposite magnetism to the second magnetic member, through the first magnetic member and the second magnetic member, the slider can firmly seal the communication port, avoiding the liquid in the internal space of the container from flowing out through the communication port.

[0034] Compared with traditional mechanical structures such as springs and silica gels, the first magnetic member and the second magnetic member will not wear or age due to long-term use, improving the durability and lifespan of the cup lid.

[0035] The magnetic force ensures that the slider can stay stably in the designated position, preventing poor sealing caused by the offset of the slider position and ensuring safety when filling with hot water.

[0036] Precisely control the opening and closing positions of the slider to ensure that the communication port is completely sealed when not in use, preventing liquid leakage, and is particularly suitable for containers such as thermos cups that need to keep liquids for a long time.

[0037] Since the magnetic poles of the first magnetic member and the second magnetic member are opposite, a reaction force is generated when the second magnetic member slides past the midpoint of the first magnetic member, making the opening and closing of the cup lid very smooth to enhance the user experience.

[0051] Next, the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0052] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "rear", and similar expressions used herein are only for the purpose of illustration.

[0053] Next, some embodiments of the present application will be described in detail in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0054] An embodiment of the present application provides a cup lid 100, including:

[0055] A lid body 110, provided with a sliding groove 110a and a communication port 110b communicating with the sliding groove 110a, and the communication port 110b is used to communicate the internal space of the container with the external space;

[0056] A slide block 120, slidably disposed in the sliding groove 110a;

[0057] A first magnetic part 130, disposed in the sliding groove 110a;

[0058] A second magnetic part 140, disposed on the slide block 120, and one side of the first magnetic part 130 close to the second magnetic part 140 is arranged with opposite magnetism to the second magnetic part 140;

[0059] Wherein, the first magnetic part 130 and the second magnetic part 140 repel each other, so that the slide block 120 slides along the sliding groove 110a to block the communication port 110a, so that the lid body 110 seals the internal space of the container.

[0060] Please refer to Figures 1-6, in this embodiment, the slider 120 is located at one end of the chute 110a. At this time, the communication port 110b is blocked by the slider 120, isolating the internal space of the container from the external space, and the liquid is not likely to flow out.

[0061] When the user needs to drink, the slider 120 is pushed to start sliding along the length direction of the chute 110a.

[0062] Until the other end of the chute 110a, the communication port 110b is opened, the internal space of the container is communicated with the external space, and the liquid can flow out.

[0063] After the user finishes using it, the slider 120 slides back to the initial position in the opposite direction manually, blocking the communication port 110b again to achieve sealing. Since the side of the first magnetic member 130 close to the second magnetic member 140 is arranged with opposite magnetism to the second magnetic member 140, through the first magnetic member 130 and the second magnetic member 140, the slider 120 can firmly seal the communication port 110b, preventing the liquid in the internal space of the container from flowing out through the communication port 110b.

[0064] Compared with traditional mechanical structures such as springs and silica gels, the first magnetic member 130 and the second magnetic member 140 will not be worn or aged due to long-term use, improving the durability and lifespan of the cup lid 100.

[0065] The magnetic force ensures that the slider 120 can stay stably at the specified position, preventing poor sealing caused by the position deviation of the slider 120 and ensuring safety when filling with hot water.

[0066] Precisely control the opening and closing positions of the slider 120 to ensure that the communication port 110b is completely sealed when not in use, preventing liquid leakage, and is especially suitable for containers such as thermos cups that need to keep liquids for a long time.

[0067] Since the first magnetic member 130 and the second magnetic member 140 have opposite magnetism, a reaction force is generated when the second magnetic member 140 slides past the midpoint of the first magnetic member 130, making the opening and closing of the cup lid 100 very smooth to enhance the user experience.

[0068] It should be further noted that since the side of the first magnetic member 130 close to the second magnetic member 140 is magnetically opposite to the second magnetic member 140 (the position of the first magnetic member 130 close to the bottom of the second magnetic member 140 is magnetically opposite to the top of the second magnetic member 140), when the cup lid 110 is opened, the slider 120 slides in the chute 110a. When the slider 120 slides to the position of the first magnetic member 130, at this time, the second magnetic member 140 coincides with the first magnetic member 130 in the vertical direction. When continuing to slide, the slider 120 drives the second magnetic member 140 to slide. At this time, the first magnetic member 130 generates a repulsive force on the second magnetic member 140 to push the slider 120 to move, so that the slider 120 abuts against the inner wall of the chute 110a, and the communication port 110b is communicated with the outside.

[0069] When the cup lid 110 is closed, the slider 120 slides in the chute 110a. When the slider 120 slides to the position of the first magnetic member 130, at this time, the second magnetic member 140 coincides with the first magnetic member 130 in the vertical direction. When continuing to slide, the slider 120 drives the second magnetic member 140 to slide. At this time, the first magnetic member 130 generates a repulsive force on the second magnetic member 140 to push the slider 120 to move, so that the slider 120 completely blocks the communication port 110b in the vertical direction to seal the communication port 110b.

[0070] In this embodiment, the general shape of the lid body 110 is a circular plate shape, and in other embodiments, it can be adjusted according to the shape of the container opening, for example: square, oval, etc.

[0071] In this embodiment, the chute 110a is formed by opening along the side of the lid body 110 towards the geometric center, and its outer shape is approximately a rectangular groove.

[0072] In this embodiment, the slider 120 is a rectangular block and is adapted to the chute 110a.

[0073] In this embodiment, both the first magnetic member 130 and the second magnetic member 140 are magnets, and their shapes are square magnets, for example: square rubidium magnets, and in other embodiments, they can be circular or other shapes.

[0074] In at least one embodiment of the present application, the lid body 110 has a receiving surface 110c, and a positioning groove 110d is opened on the receiving surface 110c;

[0075] The cup lid 100 further includes:

[0076] A capsule rotor 150, which is movably received in the positioning groove 110d and is attracted to the first magnetic member 130 to adsorb the capsule rotor 150 in the positioning groove 110d.

[0077] Please refer to Figures 1-6, in this embodiment, the capsule rotor 150 is placed in the positioning groove 110d on the receiving surface 110c of the cover 110.

[0078] After the capsule rotor 150 is placed in the positioning groove 110d, the first magnetic member 130 attracts the capsule rotor 150 by magnetic force, so that it is firmly adsorbed in the positioning groove 110d and will not fall off easily.

[0079] When the capsule rotor 150 needs to be used, the capsule rotor 150 is directly taken out of the positioning groove 110d and placed into the internal space of the container for use. The liquid in the internal space of the container can be stirred by the capsule rotor 150.

[0080] It should be noted that the capsule rotor 150 is made of a magnetizable material, and both ends are semicircular and the middle part is columnar in shape. The magnetizable material can be iron, nickel, cobalt, etc., and in this embodiment, it can be one of the above materials.

[0081] The positioning groove 110d is provided at the geometric center of the cover 110, and is a groove formed by the depression of the geometric center of the receiving surface 110c. The shape of the positioning groove 110d is similar to the outer shape of the capsule rotor 150.

[0082] The container can be a cup, a mixing cup, a jar, etc., including but not limited to the above items.

[0083] The receiving surface 110c is a plane on which the cover 110 is received inside the container, not the circumferential surface.

[0084] The cup cover 100 adopts a push-pull type, and the first sliding groove 110f and the second sliding groove 110g are respectively opened on both sides. When installing, push it in forcefully, and it can slide in smoothly and be permanently stuck. With the help of the magnet, a good automatic return feel of the push-pull switch can be generated.

[0085] In at least one embodiment of the present application, the cover 110 has a shielding surface 110e facing away from the receiving surface 110c. The shielding surface 110e is provided with a first sliding groove 110f and a second sliding groove 110g. Both the first sliding groove 110f and the second sliding groove 110g communicate with the sliding groove 110a. Both sides of the slider 120 respectively penetrate through the sliding groove 110a and extend into the first sliding groove 110f and the second sliding groove 110g.

[0086] In at least one embodiment of the present application, both ends of the sliding groove 110a have a first position 110h and a second position 110i, and the communication port 110b is provided at the first position 110h;

[0087] Among them, slide the slider 120 so that the slider 120 slides from the first position 110h to the second position 110i along the length direction of the chute 110a, so that the internal space of the container communicates with the outside through the communication port 110b. Slide the slider 120 in the reverse direction, and the first magnetic member 130 and the second magnetic member 140 repel each other, so that the slider 120 completely blocks the communication port 110b along the direction perpendicular to the shielding surface 110e to seal the internal space of the container.

[0088] In at least one embodiment of the present application, a first limiting portion 112 is formed by the inner wall of the chute 110a protruding toward the side close to the slider 120, and the first limiting portion 112 is arranged close to the first position 110h;

[0089] A second limiting portion 121 is provided on the side of the slider 120 close to the first limiting portion 112. An activity space 112a is formed in the area from the first limiting portion 112 to the second position 110i, and the second limiting portion 121 is located in the activity space 112a;

[0090] Among them, when the slider 120 is located at the first position 110h, the second limiting portion 121 abuts against the first limiting portion 112 to limit the slider 120 from continuing to move in the chute 110a in the direction close to the first position 110h; slide the slider 120 along the direction close to the second position 110i, so that the second limiting portion 121 slides in the activity space 112a, so that the internal space of the container communicates with the outside through the communication port 110b.

[0091] Please refer to Figures 1-6 , in this embodiment, the slider 120 is located at the first position 110h of the chute 110a, blocking the communication port 110b, and the inside of the container is isolated from the outside. Both sides of the slider 120 are located in the first sliding groove 110f and the second sliding groove 110g respectively to ensure its stability.

[0092] The user pushes and pulls the slider 120 to slide the slider 120 along the chute 110a to overcome the repulsive force of the first magnetic member 130 on the second magnetic member 140. The movement track of the slider 120 in the chute 110a is guided by the first sliding groove 110f and the second sliding groove 110g and slides to the second position 110i. At this time, due to the influence of the repulsive force of the first magnetic member 130 on the second magnetic member 140, the slider 120 will be fixed at the second position 110i.

[0093] The communication port 110b is opened, the internal space of the container communicates with the outside, and the liquid can flow out.

[0094] Both sides of the slider 120 slide within the first sliding groove 110f and the second sliding groove 110g, ensuring the stability and smooth movement of the slider 120 within the sliding groove 110a.

[0095] After use, the user applies an external force to slide the slider 120 reversely back to the first position 110h.

[0096] The slider 120 returns to the initial position (the first position 110h), covering the communication port 110b, ensuring that the interior of the container is isolated from the exterior again. At this time, the repulsive force of the first magnetic member 130 on the second magnetic member 140 will fix the slider 120 at the first position 110h, achieving sealing.

[0097] The polarity of the side of the first magnetic member 130 close to the second magnetic member 140 is the N pole, and the polarity of the side of the second magnetic member 140 close to the first magnetic member 130 is the N pole. In other embodiments, they can both be the S pole.

[0098] The movement of the slider 120 is guided by the first sliding groove 110f and the second sliding groove 110g, ensuring the smoothness and stability of the sliding process and avoiding jamming.

[0099] When the slider 120 is at the first position 110h, the first limiting portion 112 and the second limiting portion 121 ensure its stability, completely covering the communication port 110b, providing reliable sealing and preventing liquid leakage.

[0100] One side of the first limiting portion 112 close to the first position 110h is provided with an inclined surface, and the other side is provided with an abutting surface. The inclined surface facilitates the guiding of the second limiting portion 121 into the moving space 112a. The first limiting portion 112 is a block designed as a right trapezoid.

[0101] The second limiting portion 121 is a rectangular block.

[0102] Due to the repulsive force of the magnetic members, the sealing effect of the slider 120 is better, and the user can conveniently open and close the communication port 110b, which is suitable for occasions with frequent use.

[0103] When the communication port 110b is closed, the slider 120 can reliably cover it, preventing hot water or other liquids from leaking and avoiding safety hazards such as scalding.

[0104] The first magnetic member 130 and the second magnetic member 140 have less wear compared to traditional mechanical components. The sliding groove 110a, the second sliding groove 110g, and the first sliding groove 110f reduce friction and extend the service life of the cup lid 100.

[0105] The first sliding groove 110f and the second sliding groove 110g are both elongated grooves. The two sides of the slider 120 are provided with elongated sliding portions, and the two sliding portions are respectively received in the first sliding groove 110f and the second sliding groove 110g.

[0106] In at least one embodiment of the present application, the receiving surface 110c protrudes to form a mounting portion 111;

[0107] The cup lid 100 further has a sealing ring disposed around the outer peripheral surface of the mounting portion 111.

[0108] Please refer to Figures 1-6 , in this embodiment, the mounting portion 111 protrudes from the receiving surface 110c, and a sealing ring is disposed around its outer peripheral surface.

[0109] The mounting portion 111 and the sealing ring cooperate to ensure effective sealing when the cup lid 100 is mounted on the container.

[0110] When the cup lid 100 is mounted on the container, the mounting portion 111 and the sealing ring first come into contact with the opening portion of the container.

[0111] As the cup lid 100 is gradually tightened or pressed onto the container, the sealing ring will be squeezed and closely adhere to the inner wall or edge of the container.

[0112] After the sealing ring is compressed, under the support of the mounting portion 111, a tight seal is formed.

[0113] The sealed state ensures that the liquid inside the container will not leak, and can remain airtight even in the case of tilting or inversion.

[0114] The outer shape of the mounting portion 111 is generally in the shape of a "D", and the sealing ring is sleeved outside the mounting portion 111.

[0115] The shape of the sealing ring (not marked in the figure) is generally the same as the outer shape of the mounting portion 111, and is made of silicone material.

[0116] The mounting portion 111 protrudes from the receiving surface 110c in a direction away from the shielding surface 110e to form a convex portion, and presents an annular shape of a "D".

[0117] In at least one embodiment of the present application, a first mounting groove 110j is formed in the sliding groove 110a, the first magnetic member 130 is fixed in the first mounting groove 110j, and the first mounting groove 110j communicates with the moving space 112a.

[0118] In at least one embodiment of the present application, a second mounting groove 120a is formed on one side of the slider 120 close to the receiving surface 110c, and the second magnetic member 140 is fixed in the second mounting groove 120a.

[0119] Please refer to Figures 1-6 , in this embodiment, the first magnetic member 130 is fixed in the first installation groove 110j within the sliding groove 110a, the second magnetic member 140 is fixed in the second installation groove 120a of the slider 120, and the first magnetic member 130 and the second magnetic member 140 are arranged opposite to each other but have opposite magnetic polarities.

[0120] The slider 120 is located at the initial position of the sliding groove 110a, the communication port 110b is blocked, and the interior of the container is isolated from the outside.

[0121] When a user applies an external force, the slider 120 starts to slide within the sliding groove 110a.

[0122] The slider 120 slides to the other end (the second position 110i) of the sliding groove 110a, the communication port 110b is opened, the interior space of the container is communicated with the outside, and the liquid can flow out.

[0123] At this time, the slider 120 slides stably within the active space 112a to ensure the complete opening of the communication port 110b.

[0124] After use, the user applies an external force to slide the slider 120 back to the initial position in the reverse direction.

[0125] As the slider 120 slides within the sliding groove 110a, the repulsive force between the first magnetic member 130 and the second magnetic member 140 pushes the slider 120 back to the initial position, blocking the communication port 110b to achieve sealing.

[0126] The sliding groove 110a provides a track for the slider 120 to slide, the active space 112a ensures that the slider 120 has sufficient movement space, and the interaction force between the first magnetic member 130 and the second magnetic member 140 makes the sliding process of the slider 120 smoother and more stable.

[0127] When the slider 120 slides within the sliding groove 110a, it can accurately block or open the communication port 110b. The repulsive force of the first magnetic member 130 ensures the stability of the slider 120 at the first position 110h, thereby improving the sealing effect and preventing liquid leakage.

[0128] The sliding of the slider 120 is achieved through the interaction between the first magnetic member 130 and the second magnetic member 140, reducing the wear of the mechanical structure and extending the service life of the cup lid 100.

[0129] In at least one embodiment of the present application, the slider 120 has a blocking end 122. The distance from the second magnetic member 140 to the blocking end 122 is denoted as a, the length of the sliding groove 110a is denoted as b, and the maximum distance from the first magnetic member 130 to the first position 110h is denoted as c, satisfying the relationship: a < c < b.

[0130] In at least one embodiment of the present application, the slider 120 has a pushing end 123 disposed away from the blocking end 122. The distance from the second magnetic member 140 to the pushing end 123 is denoted as d, and the maximum distance from the first magnetic member 130 to the second position 110i is denoted as e, satisfying the relational expression: d < e;

[0131] Wherein, at the first position 110h and the second position 110i of the slider 120, the first magnetic member 130 and the second magnetic member 140 repel each other.

[0132] Please refer to Figures 1-6 , in this embodiment, the slider 120 is located at the first position 110h of the chute 110a, and the blocking end 122 blocks the communication port 110b, isolating the inside of the container from the outside.

[0133] Due to the distance relationship (a < c), there is a repulsive force between the first magnetic member 130 and the second magnetic member 140 to fix the slider 120 at the first position 110h through the second magnetic member 140. At this time, the first limiting portion 112 and the second limiting portion 121 are in contact to continuously seal the communication port 110b.

[0134] The user applies an external force to push the slider 120 to slide reversely along the chute 110a.

[0135] During the process of the slider 120 sliding from the first position 110h to the second position 110i, the first magnetic member 130 and the second magnetic member 140 always interact with each other.

[0136] The slider 120 slides to the second position 110i of the chute 110a, and the communication port 110b is opened, and the internal space of the container communicates with the outside.

[0137] At this time, the pushing end 123 of the slider 120 is at the second position 110i. The distance relationship between the first magnetic member 130 and the second magnetic member 140 is (d < e), and the repulsive force between the first magnetic member 130 and the second magnetic member 140 ensures that the slider 120 is stable at the second position 110i.

[0138] After use, the user reversely slides the slider 120 back to the first position 110h by an external force.

[0139] The slider 120 slides in the chute 110a, and there is a repulsive force between the first magnetic member 130 and the second magnetic member 140 to ensure that the slider 120 blocks the communication port 110b to achieve sealing.

[0140] The above are only the embodiments of the present application. It should be noted here that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present application, but these all fall within the protection scope of the present application.
