Description

Technical Field

[0001] This utility model relates to the field of water cup technology, and in particular to a screwless cup lid that is easy to open. Background Technology

[0002] Most common water cups nowadays use threaded connections between the lid and the body, requiring users to use both hands to unscrew the lid to drink. This can easily lead to leaks due to the lid not being screwed on properly or to the lid being too tight to open, making it inconvenient to use. As a result, push-button lids have appeared on the market, allowing users to open the lid with one hand, making it extremely convenient and expanding the usage scenarios of water cups.

[0003] The reference application, 202220965160.X, entitled "Press-type Threadless Cup Lid," includes a lid that fits over the mouth of a cup. The lid has a through hole in the center, and the inner wall of the through hole has symmetrically arranged grooves and guide notches along the axial direction. A locking element and a button are located within the through hole. The button is fitted onto the upper part of the locking element. The locking element has symmetrically arranged inclined rods and symmetrically arranged guide sliders extending into the grooves. Each inclined rod has a locking hook at its lower end that passes radially through the guide notch. The inner wall of the cup mouth has an annular groove that engages with the locking hooks. The lower end of the button has a pressing slider that slides with the corresponding inclined rod. However, with this type of cup lid, the lid and cup body remain connected after unlocking. When the user removes the lid from the cup, the lid's travel distance is relatively long, making it inconvenient to use. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a threadless cup lid that is easy to open, solving the problem of the long travel distance and inconvenience of traditional push-button cup lids when removed.

[0005] The technical solution adopted by this utility model is: a threadless cup lid that is easy to open, including a lid body and a base. The base is provided with a mounting groove, and a pressing member is provided in the mounting groove. The lid body is provided with an clearance opening for the pressing member to pass through. A self-locking component is also provided in the mounting groove. The pressing member is used to control the unlocking of the self-locking component. A sleeve is slidably connected to the outer wall of the mounting groove. The sleeve and the lid body abut against a first elastic member. The base is also provided with a flange for limiting the sleeve.

[0006] Through the above technical solution, this utility model needs to be used with a cup body, which includes the edge of the cup mouth. When the self-locking component is in the locked state, the bottom of the socket and the edge of the cup mouth abut against each other. When the user drives the pressing component to slide down to the limit state in the mounting groove, the self-locking component is in the unlocked state. The socket loses the restriction of the self-locking component, so that the lid and the socket move under the action of the elastic force of the first elastic element, so that the relative position of the cup lid and the cup body changes, and the travel distance of the cup lid when it is removed from the cup body is significantly reduced. The user can remove the cup lid faster, making it more convenient and effortless to use.

[0007] Furthermore, the top of the sleeve is provided with an annular groove, and the inner body of the cover is provided with a corresponding annular groove. One end of the first elastic member abuts in the annular groove, and the other end of the first elastic member abuts in the annular groove.

[0008] With the above technical solution, one end of the first elastic element abuts in the annular groove and the other end of the first elastic element abuts in the annular groove, making the connection of the first elastic element on the sleeve and the cover very stable, and avoiding the first elastic element from shifting or falling out when deformed or rebounding.

[0009] Furthermore, a limiting protrusion is provided at the bottom of the socket; when the socket slides downward to its limit state, the limiting protrusion and the flange abut against each other.

[0010] Through the above technical solution, the socket can slide downward under the elastic force of the first elastic element, and the flange can limit the downward sliding socket to a certain extent, preventing the socket from failing to perform its function due to excessive sliding.

[0011] Furthermore, the self-locking assembly includes a connecting cylinder and a slider, the slider being slidably connected within the mounting groove, and the outer wall of the slider and the connecting cylinder jointly abutting against a second elastic element; the slider and / or the pressing member are provided with an inclined plane transmission mechanism, when the pressing member slides downward and squeezes the slider through the inclined plane transmission mechanism, the slider retracts and compresses the second elastic element; the side wall of the mounting groove is provided with a mounting opening for the slider to extend out.

[0012] With the above technical solution, the slider and the outer wall of the connecting cylinder jointly abut against the second elastic element, so that the slider can be reset in time after being squeezed by the rebound action of the second elastic element. The setting of the inclined plane transmission mechanism makes it easier and more efficient for the pressing element to drive the slider to slide in the mounting groove.

[0013] Furthermore, the inclined plane transmission mechanism includes a first inclined plane and a second inclined plane. The first inclined plane is disposed at the bottom of the pressing member and faces downward at an angle. The second inclined plane is disposed on the slider and faces upward at an angle. The first inclined plane and the second inclined plane abut against each other, and the pressing member can drive the slider to slide laterally.

[0014] With the above technical solution, when the pressing part slides under the action of driving force, the first inclined surface facing downward presses the second inclined surface facing upward, causing the slider to slide laterally and retract inward. The cooperation between the first and second inclined surfaces makes the movement of the slider smoother and more convenient for the user to drive.

[0015] Furthermore, the slider includes a support block and an extension block connected to each other, the second inclined surface is located on the support block, the second elastic element abuts between the outer wall of the connecting cylinder and the support block, and the extension block is adapted to the mounting port.

[0016] With the above technical solution, the adapter between the protruding block and the mounting port ensures that the slider can extend outward from the mounting port without obstruction, and the slider can contact the pressing element through the second inclined surface on the support block, so that the driving force can be smoothly transmitted from the pressing element to the slider.

[0017] Furthermore, a protruding strip is provided on the outer wall of the pressing member, and a positioning slot is provided on the inner wall of the mounting groove accordingly, with the protruding strip always slidably connected in the positioning slot.

[0018] Through the above technical solution, the convex strip is always slidably connected in the positioning slot, so that the pressing part can always be located in the mounting slot during the sliding process, making the connection between the pressing part and the base very firm. Moreover, the cooperation between the convex strip and the positioning slot can play a certain guiding role for the pressing part, effectively preventing the pressing part from shifting during use.

[0034] See Figures 1 to 8 As shown, a convenient-to-open threadless cup lid includes a lid body 1 and a base 2. The base 2 is provided with a mounting groove 3, and a pressing member 4 is provided in the mounting groove 3. The lid body 1 is provided with a clearance opening 5 for the pressing member 4 to pass through. A self-locking component is also provided in the mounting groove 3. The pressing member 4 is used to control the unlocking of the self-locking component. A sleeve 6 is slidably connected to the outer wall of the mounting groove 3. The sleeve 6 and the lid body 1 abut against a first elastic member 7. The base 2 is also provided with a flange 8 for limiting the sleeve 6. This invention requires the use of a cup body, which includes the rim of the cup. When the self-locking component is in the locked state, the bottom of the sleeve 6 abuts against the rim of the cup. When the user drives the pressing component 4 to slide downwards to the limit in the mounting groove 3, the self-locking component is in the unlocked state, and the sleeve 6 loses the restriction of the self-locking component. This allows the lid 1 and the sleeve 6 to move under the elastic force of the first elastic component 7, causing a change in the relative position of the cup lid and the cup body. This significantly reduces the travel distance when the cup lid is removed from the cup body, allowing the user to remove the cup lid more quickly and making it more convenient and effortless to use.

[0035] See Figures 2-4 As shown, the top of the sleeve 6 is provided with an annular groove 9, and the cover 1 is correspondingly provided with an annular groove 10. One end of the first elastic member 7 abuts in the annular groove 9, and the other end of the first elastic member 7 abuts in the annular groove 10. The fact that one end of the first elastic member 7 abuts in the annular groove 9 and the other end of the first elastic member 7 abuts in the annular groove 10 makes the connection between the first elastic member 7 and the sleeve 6 and the cover 1 very stable, preventing the first elastic member 7 from shifting or falling out during deformation or rebound.

[0036] See Figure 2 , 3 As shown in Figures 6 and 8, a limiting protrusion 11 is provided at the bottom of the socket 6; when the socket 6 slides downward to its limit, the limiting protrusion 11 and the flange 8 abut against each other. The socket 6 can slide downward under the elastic force of the first elastic member 7, and the flange 8 can limit the downward sliding socket 6 to a certain extent, preventing the socket 6 from failing to perform its function due to excessive sliding.

[0037] See Figures 2-8 As shown, the self-locking assembly includes a connecting cylinder 12 and a slider 13. The slider 13 is slidably connected within the mounting groove 3. The outer walls of the slider 13 and the connecting cylinder 12 abut against a second elastic element 14. An inclined plane transmission mechanism is provided on the slider 13 and / or the pressing member 4. When the pressing member 4 slides downwards and presses the slider 13 through the inclined plane transmission mechanism, the slider 13 retracts and compresses the second elastic element 14. A mounting opening 15 is provided on the side wall of the mounting groove 3 for the slider 13 to extend out. The fact that the outer walls of the slider 13 and the connecting cylinder 12 abut against the second elastic element 14 allows the slider 13 to promptly reset after being pressed, thanks to the rebound effect of the second elastic element 14. The inclined plane transmission mechanism makes it more efficient and less effort-intensive for the pressing member 4 to drive the slider 13 to slide within the mounting groove 3.

[0038] The inclined plane transmission mechanism can be composed of two mutually cooperating inclined planes, or it can be composed of a single inclined plane and a slider 13 or a pressing member 4. This utility model selects two inclined planes to form an inclined plane transmission mechanism, which makes it easier for the user to drive the pressing member 4 to squeeze the slider 13.

[0039] Preferably, both the first elastic element 7 and the second elastic element 14 are springs.

[0040] See Figure 2 , 3 As shown in Figures 5 and 7, the inclined plane transmission mechanism includes a first inclined plane 16 and a second inclined plane 17. The first inclined plane 16 is located at the bottom of the pressing member 4, with its angle downwards. The second inclined plane 17 is located on the slider 13, with its angle upwards. The first inclined plane 16 and the second inclined plane 17 abut against each other, and the pressing member 4 can drive the slider 13 to slide laterally. When the pressing member 4 slides under the action of the driving force, the downward-angled first inclined plane 16 presses against the upward-angled second inclined plane 17, causing the slider 13 to slide laterally and retract inwards. The cooperation between the first inclined plane 16 and the second inclined plane 17 makes the movement of the slider 13 smoother, and it is easier and less effort for the user to drive it.

[0041] See Figure 2 , 3 As shown in Figure 7, the slider 13 includes a support block 131 and an extension block 132 connected to each other. A second inclined surface 17 is located on the support block 131. A second elastic element 14 abuts between the outer wall of the connecting cylinder 12 and the support block 131. The extension block 132 is adapted to the mounting port 15. The adaptation of the extension block 132 and the mounting port 15 ensures that the slider 13 is not obstructed when it extends outward from the mounting port 15. The slider 13 can contact the pressing element 4 through the second inclined surface 17 on the support block 131, so that the driving force can be smoothly transmitted from the pressing element 4 to the slider 13.

[0042] See Figure 3 ,5 As shown in Figure 8, a protruding strip 18 is provided on the outer wall of the pressing component 4, and a corresponding positioning groove 19 is provided on the inner wall of the mounting groove 3. The protruding strip 18 is always slidably connected within the positioning groove 19. The fact that the protruding strip 18 is always slidably connected within the positioning groove 19 ensures that the pressing component 4 remains within the mounting groove 3 during sliding, making the connection between the pressing component 4 and the base 2 very firm. Furthermore, the cooperation between the protruding strip 18 and the positioning groove 19 can provide a certain guiding effect for the pressing component 4, effectively preventing the pressing component 4 from shifting during use.

[0043] When using this invention, it needs to be used with a cup body, which includes the rim of the cup. When the slider 13 engages and locks the cup body, the bottom of the sleeve 6 abuts against the rim of the cup. When the user drives the pressing part 4 to slide downward in the mounting groove 3 to its limit, the first inclined surface 16 facing downward presses the second inclined surface 17 facing upward, causing the slider 13 to retract and compress the second elastic element 14. The slider 13 and the cup body are no longer in contact, and the restriction of the sleeve 6 is released. This allows the lid 1 and the sleeve 6 to move under the elastic force of the first elastic element 7, changing the relative position of the lid and the cup body. This significantly reduces the travel distance when the lid is removed from the cup body, allowing the user to remove the lid more quickly and making it more convenient and effortless to use.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
