Description

Technical Field

[0001] This application relates to the technical field of heat preservation cup sealing technology, and particularly relates to a screwless press-type heat preservation cup. Background Art

[0002] A sealed heat preservation cup is a container designed to maintain the temperature (hot or cold) of a liquid, characterized by its excellent sealing performance and heat preservation effect. To meet the needs of consumers, the structural design of heat preservation cups is constantly updated and optimized with the progress of technology.

[0003] In the existing design of heat preservation cups, a screw cap is the most common sealing method. This design requires the user to rotate the cup cap to open and close it. The Chinese utility model patent with the authorization announcement number CN220713601U discloses a screwless heat preservation cup, which includes a cup body and a cup cap. The cup cap includes a cap body, a lifting member, a sealing member, a triggering member, a locking member, a first spring, a second spring, a transmission member, and a sealing cover. When in use, the lifting member is lifted upward, and the locking member is inserted into the lifting member under the action of the second spring to lock the lifting member. At this time, the sealing member is deformed under the action of the lifting member and seals against the cup body. When it needs to be opened, the triggering member is pressed downward, and the locking member is disengaged from the lifting member under the action of the guiding portion to release the pressing. The lifting member is reset upward under the action of the first spring. At this time, the sealing member returns to its original shape and cancels the sealing effect.

[0004] In view of the above related technologies, the unlocking of the cup cap in the comparative document is an upward lifting operation. Therefore, when the cup cap is taken out, there are two unlocking methods. The first is a two-handed operation, with one hand lifting the lifting member upward and the other hand pressing the cup body; the second is a single-handed operation, with one finger lifting the triggering member upward and two fingers pressing the cap body. The above two unlocking methods of the cup cap are relatively cumbersome. This application provides another screwless heat preservation cup that is convenient for disassembly and assembly. Utility Model Content

[0005] In order to facilitate the unlocking of the cup cap and the cup body, this application provides a screwless press-type heat preservation cup.

[0006] The screwless press-type heat preservation cup provided by this application adopts the following technical solutions:

[0007] A screwless press-type heat preservation cup includes a cup cap and a cup body. The cup cap includes a locking member inserted into the cup body and positioned and abutted against the cup body, an elastic sealing ring sleeved on the locking member and used for sealing and abutting against the inner wall of the cup body, a pushing assembly locked and cooperated with the locking member and used for driving the elastic sealing ring to deform, a cup cap covering the pushing assembly, and an unlocking driving member arranged on the cup cap; after the locking member and the pushing assembly are locked and cooperated, the pushing assembly drives the elastic sealing ring to deform and seal against the inner wall of the cup body, and the unlocking of the locking member and the pushing assembly is realized through the unlocking driving member.

[0008] By adopting the above technical solution, when using the above-mentioned threadless heat-insulated cup, the locking member of the cup lid is inserted into the cup body, the pushing component is pressed, and the pushing component and the locking member cooperate to lock, so that the elastic sealing ring deforms under the push of the pushing component and abuts against the inner wall of the cup body, realizing the sealed connection between the cup body and the cup lid; when it is necessary to open the cup lid for drinking, press down the unlocking driving member to release the lock between the locking member and the pushing component, so that the elastic deformation member resumes deformation and releases the sealed connection between the cup body and the cup lid. At this time, the cup lid can be removed from the cup body; compared with the lifting unlocking method in the comparative document, the downward pressing unlocking method of the present application only requires one finger of one hand to unlock, which has the effects of labor-saving operation and convenient use, and does not require the operation of holding the cup body with the other hand or lifting the locking member and fixing the cup body with one hand simultaneously as required in the comparative document.

[0009] Optionally, a positioning post is arranged on one side of the locking member facing the pushing component, and a first elastic member is sleeved outside the positioning post. Two ends of the first elastic member respectively abut against the locking member and the pushing component. A locking groove is formed on the side wall of the positioning post, and the pushing component has a locking block inserted into the locking groove.

[0010] By adopting the above technical solution, the locking structure of the locking member and the pushing component is disclosed. When the pushing component moves towards the locking member and the locking block corresponds to the locking groove, the locking block is inserted into the locking groove to realize the locking of the locking member and the pushing component. Through the arrangement of the first elastic member, after the locking between the locking member and the pushing component is released, the first elastic member drives the pushing component to move and reset in a direction away from the locking member, and at the same time releases the pressing of the pushing component on the elastic seal.

[0011] Optionally, the pushing component includes a pushing ring, a pushing block limitedly installed on the pushing ring, and a second elastic member for driving the pushing block to reset. The pushing ring has a locking through hole corresponding to the positioning post. The second elastic member and the positioning post are vertically arranged, and the locking block is arranged at one end of the pushing block facing the locking through hole.

[0012] By adopting the above technical solution, the structural composition of the pushing component is disclosed. The pushing ring is arranged on the top of the locking member, used for pushing and pressing the elastic member and for the limited installation of the pushing block. The locking block is arranged on the pushing block. When the end of the positioning post passes through the pushing through hole and the locking groove corresponds to the pushing block, under the action of the second elastic member, the locking block is inserted into the locking groove to realize the locking and fixing of the locking member and the pushing ring. The locking structure is simple, the operation is convenient, and the assembly is easy.

[0013] Optionally, a first locking arc surface is arranged on one side of the locking block facing the positioning post, and the end of the positioning post has a second locking arc surface matching the first locking arc surface.

[0014] By adopting the above technical solution, when installing the cup lid, the user presses down the pushing component. Due to the arrangement of the first locking arc surface and the second locking arc surface, it is convenient for the positioning post to push the locking block. After the locking groove and the locking block correspond to each other, under the action of the second elastic member, the locking block automatically snaps into the locking groove, and the locking operation is more convenient and labor-saving.

[0015] Optionally, the pushing ring has a positioning sleeve sleeved on the positioning post, the first elastic member is sleeved on the positioning sleeve, and the positioning sleeve is sleeved on the positioning post in both the unlocked and locked states.

[0016] By adopting the above technical solution, the arrangement of the positioning sleeve on the pushing ring can ensure the coaxiality of the pushing ring and the locking member, enabling the positioning post to accurately pass through the pushing through hole and improving the stability of the pushing ring during sliding.

[0017] Optionally, a plurality of pushing arc blocks are circumferentially arranged on the outer edge of one side of the pushing ring facing the locking member. The locking member has pushing through holes corresponding to the pushing arc blocks one by one, and the pushing through holes communicate with the top of the elastic sealing ring.

[0018] By adopting the above technical solution, the matching structure of the pushing ring and the elastic sealing ring is disclosed. The elastic sealing ring is pressed and deformed by the plurality of pushing arc blocks on the pushing ring. When the pushing ring moves towards the locking member, the pushing arc blocks pass through the pushing through holes to drive the elastic sealing ring to move downward synchronously. The bottom of the elastic sealing ring abuts against the locking member, thereby realizing the expansion and deformation of the elastic sealing ring.

[0019] Optionally, the pushing ring and the cup cap are in plug-in fit. The cup cap is provided with a sliding groove for arranging the unlocking driving member. The bottom wall of the sliding groove is provided with an unlocking through hole corresponding to the positioning post. The end of the pushing block is provided with an unlocking block for the unlocking driving member to abut against. The radial distance from the unlocking block to the positioning post is less than the radial distance from the locking block to the positioning post.

[0020] By adopting the above technical solution, the matching mode of the unlocking driving member and the pushing component is disclosed. The unlocking driving member and the positioning post are correspondingly arranged. When unlocking is required, the unlocking driving member is pressed downward so that it abuts against the unlocking block, driving the whole pushing block to move away from the positioning post, thereby realizing the separation of the locking block and the locking groove, and realizing the overall upward movement of the pushing component under the action of the first elastic member, and unlocking the locking member and the pushing component.

[0021] Optionally, the unlocking block is provided with a first unlocking arc surface on the side facing the cup cap, and the unlocking driving member has a second unlocking arc surface in abutting fit with the first unlocking arc surface.

[0022] By adopting the above technical solution, when pressing the unlocking driving member, the first unlocking arc surface and the second unlocking arc surface are provided, so that the user can drive the movement of the pushing block through the unlocking driving member more effortlessly.

[0023] Optionally, the cup cap is further provided with a limiting assembly for limiting the unlocking drive member, the limiting assembly comprising a limiting ring rotatably provided on the cup cap and an elastic plunger provided on the cup cap, the side wall of the limiting ring is provided with a toggle block extending to the side wall of the cup cap, and the bottom of the limiting ring is provided with two limiting grooves that cooperate with the plunger head of the elastic plunger at intervals along the circumferential direction of the axis;

[0024] The unlocking drive member is arranged in the limiting ring, and a plurality of pressing limiting parts are circumferentially provided on the outer side of the unlocking drive member. The limiting ring has a limiting locking groove corresponding to the pressing limiting part, and the limiting locking groove includes a first groove extending through the bottom wall of the sliding groove and a second groove for limiting the sliding of the unlocking drive member.

[0025] By adopting the above technical solution, the setting of the limit assembly can play a limiting role on the unlocking drive member. When the limit ring is in a normal state, one of the limit grooves and the elastic plunger member cooperates to lock. At this time, the pressing limit portion of the side wall of the unlocking drive member corresponds to the second groove, and the unlocking drive member cannot be pressed down to unlock; when unlocking is required, the toggle block is rotated to make the other limit groove of the limit ring and the elastic plunger member cooperate to lock. At this time, the pressing limit portion of the unlocking drive member corresponds to the first groove, and pressing the unlocking drive member can realize the sliding of the push block, thereby realizing unlocking.

[0026] Optionally, the locking member includes a first locking ring and a second locking ring sealingly connected to the first locking ring, the exhaust chamber is formed between the first locking ring and the second locking ring, the two ends of the elastic sealing ring respectively abut the first locking ring and the second locking ring, the elastic sealing ring has an elastic deformation portion, and a deformation gap is formed between the elastic deformation portion and the side wall of the second locking ring.

[0027] By adopting the above technical solution, the structural composition of the locking member and the elastic sealing ring is disclosed. The locking member includes a first locking ring and a second locking ring. The disassembly and assembly connection of the two locking rings facilitates the installation of the elastic sealing member, and an exhaust chamber for exhaust is formed after the two locking rings are sealed and connected. When the arc block pushes the elastic sealing member, the elastic sealing member is driven to move toward the first locking ring, and the deformed elastic deformation part expands outward and abuts against the inner wall of the cup body.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The unlocking method of pressing downwards in the present application, compared with the unlocking method of lifting upwards in the comparative document, only requires one finger of one hand to achieve unlocking, which has the effects of labor-saving operation and convenient use, without the need to use the other hand to hold the cup body or to simultaneously lift the locking member and fix the cup body with one hand as required in the comparative document;

[0030] 2. Through the settings of the first locking arc surface and the second locking arc surface, and the first unlocking arc surface and the second unlocking arc surface in the present application, the user can lock and unlock the cup lid more labor-savingly;

[0031] 3. Through the setting of the limiting component in the present application, the unlocking driving member can be limited, reducing the occurrence of accidental touching of the unlocking driving member. Description of the Drawings

[0043] The following will Figure 1-10 further elaborate on this application in detail.

[0044] The embodiment of this application discloses a screwless press-type thermos cup.

[0045] Referring to Figure 1 , a screwless press-type thermos cup includes a cup lid 1 and a cup body 2, and the cup lid 1 and the cup body 2 are detachably connected. The structure of the cup body 2 is the same as that of the prior art. There is a water storage chamber 21 inside the cup body 2, and a vacuum interlayer is also provided between the water storage chamber 21 and the inner wall of the cup body 2 to improve the heat preservation effect of the cup body 2. Define the bottom of the cup body 2 as the lower side and the top surface of the cup lid 1 as the upper side.

[0046] The cup cover 1 includes a locking member 3, an elastic sealing ring 4, a pushing assembly 5, a cup cap 6, an unlocking drive member 7 and a limiting assembly 8. The locking member 3 is positioned against the cup body 2, and the elastic sealing ring 4 is limitedly installed on the locking member 3. The pushing assembly 5 is slidably installed on the locking member 3, and the pushing assembly 5 and the locking member 3 are locked together, so that the cup cover 1 has two states: locked and unlocked. The cup cap 6 and the pushing assembly 5 are connected and fixed, and the unlocking drive member 7 and the limiting assembly 8 are both provided on the cup cap 6. The locking of the pushing assembly 5 and the locking member 3 is achieved by pressing the cup cap 6 downward, and the unlocking of the two is achieved by pressing the unlocking drive member 7. The limiting assembly 8 is used to limit the pressing of the unlocking drive member 7 to prevent accidental touching.

[0047] Reference Figure 2 and Figure 3 The locking member 3 includes a first locking ring 31 and a second locking ring 32, which are connected by a threaded seal. The cross-section of the first locking ring 31 in the axial direction is T-shaped, and it includes a first positioning platform 311 for abutting one end of the elastic sealing ring 4 and a threaded connection column 312 provided on the top of the first positioning platform 311. The radial cross-section of the first positioning platform 311 is circular, and it is coaxially arranged with the threaded connection column 312. The bottom of the first positioning platform 311 is symmetrically provided with a toggle protrusion 3111 for rotation along the axis to facilitate the disassembly and assembly of the first locking ring 31 and the second locking ring 32.

[0048] The second locking ring 32 has an inverted T-shaped cross-section along the axis. It includes a second positioning platform 321 for abutting the open end surface of the cup body 2 and for abutting the other end of the elastic sealing ring 4, and a threaded connection sleeve 322 for mating with the threaded connection column 312. The end surface of the threaded connection sleeve 322 has a threaded hole that threadably mates with the threaded connection column 312.

[0049] Combine Figure 4 and Figure 5 A sealing ring groove 3121 is formed on the outer side wall of the end portion of the threaded connecting column 312 , and a sealing ring 33 is installed in the sealing ring groove 3121 .

[0050] The elastic sealing ring 4 is an elastic rubber sleeve of the prior art, and its two ends abut against the first positioning platform 311 and the second positioning platform 321 respectively. The bottom end face of the threaded connection sleeve 322 also has a mounting ring groove 3222 for one end of the elastic sealing ring 4 to be limited and clamped. The elastic sealing ring 4 has an elastic deformation part 41 on the side close to the first positioning platform 311, and the elastic deformation part 41 is truncated as a whole. The outer wall of the threaded connection sleeve 322 has a positioning surface 3221 for the top wall of the elastic deformation part 41 to abut, and there is also a deformation gap 42 between the outer wall of the elastic deformation part 41 and the second locking ring 32, so that when the push component 5 moves toward the locking member 3, the elastic deformation part 41 is driven to expand and deform outward as a whole, and is sealed and clamped on the inner wall of the cup body 2, thereby achieving the fixation and sealing of the cup cover 1 and the cup body 2.

[0051] On one side of the top of the second locking ring 32 facing the pushing assembly 5, there is an installation groove 323, and the installation groove 323 and the threaded connection post 312 are coaxially arranged. A positioning post 324 is integrally and coaxially arranged on the bottom wall of the installation groove 323 of the second locking ring 32. A first elastic member 34 is sleeved outside the positioning post 324. The radial cross-section of the positioning post 324 is circular, and its outer diameter is smaller than the inner diameter of the installation groove 323. Two locking grooves 3241 are symmetrically opened at the end of the positioning post 324 along the axis.

[0052] Referring to Figure 3 、 Figure 4 and Figure 6 as shown in, the pushing assembly 5 includes a pushing ring 51, a pushing block 52 limitedly installed on the top of the pushing ring 51, and a second elastic member 53 connecting the pushing block 52.

[0053] The pushing ring 51 is integrally in a disc shape, and its outer diameter is adapted to the outer diameter of the second positioning platform 321. The distance from the bottom surface of the pushing ring 51 to the top surface of the second positioning platform 321 is the overall sliding range of the pushing assembly 5. A plurality of pushing arc blocks 511 for pushing the elastic sealing ring 4 are circumferentially arranged along the axis at the bottom of the pushing ring 51. The second positioning platform 321 has pushing through holes 3211 corresponding to the pushing arc blocks 511 one by one and for the pushing arc blocks 511 to pass through. The pushing arc blocks 511 extend towards the first locking ring 31 and are provided with locking arc blocks 5111 that are clamped with the second locking ring 32. The locking arc blocks 5111 are slidably limited on the side wall of the threaded connection sleeve 322. In this embodiment, the pushing ring 51 has four pushing arc blocks 511 arranged at equal intervals circumferentially.

[0054] A positioning sleeve 512 sleeving the positioning post 324 is integrally arranged at the central axis of the bottom of the pushing ring 51. The length of the positioning sleeve 512 in the axial direction is adapted to the length of the sliding gap, so that the positioning sleeve 512 is always sleeved and matched with the positioning post 324 in the locked and unlocked states of the pushing assembly 5. The inner diameter of the first elastic member 34 is larger than the outer diameter of the positioning sleeve 512, and the two ends of the first elastic member 34 respectively abut against the bottom surface of the pushing ring 51 and the bottom wall of the installation groove 323.

[0055] The pushing ring 51 has a locking through hole 513 penetrating both end faces and corresponding to the positioning post 324. The pushing assembly 5 has two pushing blocks 52, and the two pushing blocks 52 are radially slidably installed on the pushing ring 51. The top surface of the pushing ring 51 has a limiting block 514 for limited installation of the pushing block 52 and a butting block 515 for one end of the second elastic member 53 to abut against.

[0056] Both of the two pushing blocks 52 have locking blocks 521 at their ends facing the locking through hole 513 for insertion into the locking groove 3241. On the side of the pushing block 52 away from the locking block 521, there is an abutting groove 522 for the other end of the second elastic member 53 to abut against. The two ends of the second elastic member 53 respectively abut against the abutting block 515 and the bottom wall of the abutting groove 522. In the normal state of the second elastic member 53, the locking block 521 corresponds to the locking through hole 513. In this embodiment, both the first elastic member 34 and the second elastic member 53 are spring members of the prior art.

[0057] Referring to Figure 4 、 Figure 5 and Figure 6 , wherein, the locking block 521 further has a first locking arc surface 5211 at its bottom facing the locking through hole 513. The end of the positioning post 324 has a second locking arc surface 3242 that cooperates with the first locking arc surface 5211. The second locking arc surface 3242 extends toward the bottom wall of the installation groove 323 to below the locking groove 3241, so that when the user presses the pushing ring 51 to lock, the two pushing blocks 52 can be driven by the positioning post 324 to move away from each other.

[0058] The cup cap 6 covers the pushing ring 51, and the axial length of the cup cap 6 is greater than the distance between the pushing ring 51 and the second positioning platform 321, so that the inner wall of the cup cap 6 corresponds to the second positioning platform 321 in both the locked and unlocked states of the pushing assembly 5.

[0059] Combining Figure 7 and 8 , the cup cap 6 and the pushing ring 51 are inserted and fixed. The top surface of the pushing ring 51 has a plurality of insertion posts 516 on both sides of the pushing block 52. The inner top wall of the cup cap 6 has insertion sleeves 61 corresponding to and inserted with the insertion posts 516. The top of the cup cap 6 has a sliding groove 62 for installing the unlocking driving member 7. The sliding groove 62 is a circular groove, and an unlocking through hole 621 communicating with the pushing ring 51 is opened at the bottom wall. The unlocking through hole 621 and the positioning post 324 are coaxially arranged.

[0060] The unlocking driving member 7 includes an unlocking button 71 and an unlocking piece 72 disposed at the bottom of the unlocking button 71 for abutting against the pushing block 52. Both sides of the end of the pushing block 52 facing the locking through hole 513 have unlocking blocks 523 corresponding to the unlocking piece 72. Among them, the locking block 521 is located between the unlocking blocks 523, and the distance between the corresponding unlocking blocks 523 on the two pushing blocks 52 in the unlocked state is smaller than the distance between the two locking blocks 521. The unlocking block 523 is provided with a first unlocking arc surface 5231 on the side facing the cup cap 6, and the unlocking piece 72 has a second unlocking arc surface 721 that cooperates with the first unlocking arc surface 5231, so that when the user presses the unlocking driving member 7, the two pushing blocks 52 can be moved away from each other more labor - savingly.

[0061] The limiting assembly 8 includes a limiting ring 81 rotatably arranged in the sliding groove 62 and an elastic plunger 82 for locking with the limiting ring 81. The cup cap 6 also has a rotating through hole 63 horizontally connected to the outside world on the side wall of the sliding groove 62, and the limiting ring 81 is equipped with a toggle block 83 extending outside the rotating through hole 63. The toggle block 83 and the limiting ring 81 are snap-fitted, and two snap-fitting blocks 831 are provided on both sides of the end of the toggle block 83. The snap-fitting block 831 has a certain elastic deformation ability. The limiting ring 81 has a snap-fitting groove 811 for the snap-fitting block 831 to be elastically snapped into.

[0062] The horizontal arc of the rotating through-hole 63 defines the rotational range of the stop ring 81. The stop ring 81 has two locking holes 812 at its bottom end, distal from the toggle block 83. These two locking holes 812 are spaced circumferentially along the axis. The elastic plunger 82, similar in structure to conventional spring plungers, is positioned correspondingly to the locking holes 812. By rotating the toggle block 83 back and forth, the two locking holes 812 engage with the plunger head in sequence.

[0063] The limiting ring 81 has a limiting placement groove 813 that passes through the upper and lower end surfaces and is for the unlocking button 71 to be arranged. A plurality of press-limiting portions 711 are circumferentially spaced apart on the outer wall of the unlocking button 71. The press-limiting portion 711 and the unlocking button 71 are integrally formed and extend in the radial direction. The limiting ring 81 is provided with a limiting locking groove 814 corresponding to the press-limiting portion 711 in the limiting placement groove 813. The limiting locking groove 814 includes a first groove 8141 and a second groove 8142. The first groove 8141 passes through and is connected to the top of the limiting ring 81, and the axial depth of the second groove 8142 is the same as the thickness of the press-limiting portion 711.

[0064] When one locking hole 812 of the limiting ring 81 and the elastic plunger 82 are locked, the pressing limiting portion 711 corresponds to the first groove 8141. At this time, the unlocking drive member 7 is in an unlocked state and can be slid and pressed in the up and down directions. When the other locking hole 812 of the limiting ring 81 and the elastic plunger 82 are locked, the pressing limiting portion 711 corresponds to the second groove 8142. At this time, the pressing limiting portion 711 is limited by the second groove 8142 and cannot slide in the up and down directions, thereby reducing the situation of accidentally touching the unlocking drive member 7 under normal storage conditions and improving ease of use.

[0065] The top of the cup cap 6 also has a sealing cover 64 covering the sliding groove 62. The sealing cover 64 and the inner wall of the sliding groove 62 are sealed and clamped to reduce the probability of external dust and other pollution sources entering the limiting ring 81.

[0066] Second embodiment: In this embodiment, except that a handle portion 65 is provided on the cup cap 6 , the rest of the structure is consistent with that of the first embodiment.

[0067] Reference Figure 9 andFigure 10 In order to facilitate the taking of the heat preservation cup, a handle portion 65 is further provided on the outer wall of the cup cap 6, and the handle portion 65 is located on the side away from the toggle block 83. The handle portion 65 is integrally provided on the side wall of the cup cap 6, and the cross section of the handle portion 65 is U-shaped. In other embodiments, the handle portion 65 is rotatably provided on the side wall of the cup cap 6.

[0068] The embodiment of the present application is a threadless press-type sealed thermos cup. The implementation principle of the present application embodiment is as follows: when installing the cup cover 1 and the cup body 2, the positioning post 324 and the pushing block 52 are first adjusted to the unlocked state, and then the cup cover 1 is inserted into the cup body 2, and the second positioning platform 321 is positioned against the open end surface of the cup body 2; the cup cap 6 and the pushing assembly 5 are pushed downward, and the first locking arc surface 5211 and the second locking arc surface 3242 cooperate to make the positioning post 324 pass through the locking through hole 513. After the locking block 521 and the locking groove 3241 correspond to each other, the locking block 521 is automatically inserted into the locking groove 3241 under the action of the second elastic member 53, thereby locking the positioning post 324 and the pushing ring 51. The pushing arc block 511 simultaneously pushes the elastic sealing ring 4 downward, so that the elastic deformation portion 41 expands and is clamped between the first positioning platform 311 and the inner wall of the cup body 2;

[0069] When unlocking is required, first rotate the toggle block 83 to drive the limit ring 81 to rotate, so as to press the limit part 711 and the first groove 8141, and the unlocking drive member 7 is adjusted to the unlocking state; then press the unlocking drive member 7 downward so that the unlocking piece 72 passes through the unlocking through hole 621 and abuts against the unlocking block 523, and continue pressing, and under the action of the first unlocking arc surface 5231 and the second unlocking arc surface 721, the locking block 521 is driven out of the locking groove 3241; release the unlocking drive member 7, the cup cap 6 and the push ring 51 automatically reset upward under the action of the first elastic member 34, realizing the locking of the positioning column 324 and the push ring 51, and at the same time the elastic sealing ring 4 also restores its deformation, and the cup cover 1 can be removed from the cup body 2 at this time.

[0070] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
