Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a flip-top cup lid and flip-top cup with a linkage between opening, self-locking and anti-splashing. Background Technology

[0002] Flip-top cups have become popular among consumers due to their one-touch opening mechanism. However, current flip-top cups generally suffer from the following drawbacks during use:

[0003] One scenario is that the lid may be accidentally opened due to forgetting to lock it, causing liquid leakage. Furthermore, the existing self-locking structure of the flip lid is generally a sliding latch, with the entire self-locking structure concentrated in the small internal space of the button and latch, resulting in a complex structure, small parts, and inconvenient assembly.

[0004] Another situation is that the flip-top lid itself does not have an automatic pressure relief mechanism when opened, and therefore does not have a splash-proof function. Some flip-top lids do have an automatic pressure relief mechanism, but because the time difference between pressure relief and the opening action is too small, the air pressure inside the cup has not had time to be released before the lid is opened, causing the pressure relief to fail. As a result, at the moment the lid is opened, due to the high air pressure inside the cup, hot water sprays out from the spout, causing burns and posing a safety hazard. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flip-top cup lid and flip-top cup with linked opening, self-locking and anti-splashing functions. It cleverly integrates the pressure relief, opening and self-locking actions into a continuous action, and can ensure the anti-splashing effect and prevent liquid leakage caused by forgetting to lock.

[0006] This utility model is achieved through the following technical solution:

[0007] A flip-top cup lid with a linkage between opening, self-locking, and splash prevention includes a cup lid body, a flip cover rotatably mounted on the cup lid body, and a movable switch slidably mounted in a groove at the front end of the cup lid body. The first engaging part of the movable switch engages with the second engaging part of the flip cover to achieve the locking and closing of the flip cover and the cup lid body. An outer ring is rotatably fitted around the cup lid body, and a pressable button is installed in a button hole on one side of the outer ring. An installation cavity is opened on one side of the cup lid body, and a rotary switch is rotatably mounted in the installation cavity. The outer teeth of the rotary switch mesh with a section of the inner teeth of the outer ring. A plug is provided on one side of the rotary switch, and a vent plug is provided on the side wall of the installation cavity of the cup lid body. The vent plug has a vent hole connecting the inside and outside of the cup lid body.

[0008] In its natural state, under the action of the first elastic reset element, the plug of the rotary switch always elastically presses against the vent hole of the vent plug, and the button and the movable switch do not correspond perfectly. Rotating the outer ring causes the inner teeth of the outer ring to drive the rotary switch to rotate, so that the plug of the rotary switch gradually moves away from the vent hole, while the button gradually corresponds perfectly with the movable switch. Pressing the button inward pushes the movable switch backward, causing the first engaging part of the movable switch to disengage from the second engaging part of the flip cover.

[0009] As a preferred embodiment of the aforementioned flip-top cup lid, a second elastic reset member is provided between the rear end of the movable switch and the rear wall of the slide groove, and the elastic force of the second elastic reset member makes the movable switch in the front limit position.

[0010] As a preferred embodiment of the aforementioned flip-top cup lid, a toggle protrusion is provided on the outer side wall of the outer ring, next to the button hole. The protrusion height of the toggle protrusion relative to the outer side wall of the outer ring is higher than the protrusion height of the button relative to the outer side wall of the outer ring.

[0011] As a preferred embodiment of the aforementioned flip-top cup lid, a limiting rib is also provided on one side of the sliding groove at the front end of the cup lid body. In its natural state, the rear end of the button abuts against the front side of the limiting rib.

[0012] As a preferred embodiment of the above-mentioned flip-top cup lid, the cup lid body includes an inner fastener and a connecting body that are fixed together. The bottom of the inner fastener is provided with a lower limiting flange, and the top of the connecting body is provided with an upper limiting flange. The outer side wall of the connecting body, the upper limiting flange and the lower limiting flange together form an annular mounting groove for positioning and installation of the outer ring.

[0013] As a preferred embodiment of the aforementioned flip-top cup lid, the slide groove and the mounting cavity are respectively provided on the connecting body. The top of the connecting body has an insertion hole that communicates with the slide groove. The second engaging part of the flip cover includes an engaging rib provided on the inner side of the flip cover. The lower section of the engaging rib has an engaging groove. The first engaging part of the movable switch is an engaging protrusion. When the flip cover is closed, the engaging rib of the flip cover is inserted downward from the insertion hole of the connecting body into the slide groove and engages with the engaging protrusion of the movable switch.

[0014] As a preferred embodiment of the aforementioned flip-top cup lid, the inner fastener has an upwardly protruding mounting boss at the top center, and a through hole is opened on the top plate of the connecting body. The mounting boss of the inner fastener is precisely fitted into the through hole of the connecting body. A suction nozzle is provided on the mounting boss of the inner fastener, and the inside and outside of the cup lid are connected through the internal channel of the suction nozzle.

[0015] As a preferred embodiment of the aforementioned flip-top cup lid, the inner fastener and the connecting body both have vent plug mounting holes at the corresponding vent plug locations for installing the vent plug, and the vent plug mounting holes connect the inside and outside of the cup lid body.

[0016] As a preferred embodiment of the aforementioned flip-top cup lid, the first elastic reset element is a torsion spring. A vertical mounting shaft is fixed in the mounting cavity of the cup lid body. The torsion spring and the rotary switch are coaxially mounted on the mounting shaft, and the two ends of the torsion spring press against the limiting groove on the bottom wall of the mounting cavity and the rotary switch, respectively.

[0017] This utility model also discloses a flip-top cup with linkage between opening, self-locking and anti-splashing, including a cup body and a flip-top cup lid, wherein the flip-top cup lid is the flip-top cup lid described above.

[0018] This invention has the following advantages over the prior art:

[0019] This utility model provides a flip-top cup lid and flip-top cup with linked opening, self-locking, and anti-splash functions. By setting a circumferentially rotating outer ring around the main body of the lid, and having the outer teeth of a rotary switch mesh with a section of the inner teeth of the outer ring, the rotation of the outer ring and the rotation of the rotary switch are linked. Simultaneously, by controlling the rotation direction of the rotary switch, the sealing of the vent hole of the vent plug and the vent plug can be controlled, thus controlling whether pressure is released. Furthermore, the circumferential rotation of the outer ring drives the button to rotate, controlling whether the button is locked. This ingenious structural design cleverly integrates pressure release, lid opening, and self-locking actions into a continuous action, ensuring the time difference between pressure release and lid opening, thereby guaranteeing the effectiveness of pressure release. Moreover, the overall structure is simple and easy to assemble, solving the problems of complexity and difficult assembly in traditional cup lid self-locking structures. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0032] See Figures 1 to 10This embodiment discloses a flip-top cup lid with linked opening, self-locking, and anti-splash functions. It includes a cup lid body 1, a flip cover 2 rotatably mounted on the cup lid body 1 via a pivot 3, and a movable switch 5 slidably mounted in a groove 4 at the front end of the cup lid body 1. A second elastic reset element, which can be a reset spring 6, is provided between the rear end of the movable switch 5 and the rear wall of the groove 4. The elastic force of the second elastic reset element causes the movable switch 5 to be in its front limit position. When the movable switch 5 is in its front limit position, the front ends of the limiting grooves 7 on the left and right side walls of the groove 4 abut against the limiting protrusions 8 at both ends of the movable switch 5, thus limiting the forward movement of the movable switch 5 to its front limit position. When the movable switch 5 is in its front limit position, the first engaging part of the movable switch 5 engages with the second engaging part of the flip cover 2, thus closing the flip cover 2 and the cup lid body 1. An outer ring 9 is rotatably fitted around the outer edge of the cup lid body 1. A pressable button 11 is installed in a button hole 10 on one side of the outer ring 9. A limiting flange 12 is provided at the rear end of the button 11 to abut against the inner ring of the outer ring 9, preventing the button 11 from dislodging from the outer ring 9. An actuating protrusion 13 is provided on the outer wall of the outer ring 9, next to the button hole 10. The actuating protrusion 13 is located between the button hole 10 and the inner teeth 21. The protrusion height of the actuating protrusion 13 relative to the outer wall of the outer ring 9 is higher than the protrusion height of the button 11 relative to the outer wall of the outer ring 9. In this embodiment, the actuating protrusion 13 is located on the right side of the button hole 10. A mounting cavity 14 is formed on one side of the cup lid body 1. A rotary switch 15 is rotatably mounted in the mounting cavity 14. The rotary switch 15 is reset by a first elastic reset element, which is a torsion spring 16. A vertical mounting shaft 17 is fixed in the mounting cavity 14 of the cup lid body 1. The torsion spring 16 and the rotary switch 15 are coaxially mounted on the mounting shaft 17, and the two ends of the torsion spring 16 press against the limiting groove 18 on the bottom wall of the mounting cavity 14 and the stepped surface 19 of the rotary switch 15, respectively. The outer teeth 20 of the rotary switch 15 mesh with a section of the inner teeth 21 of the inner ring of the outer ring 9. A plug 22 is provided on one side of the rotary switch 15. A vent plug 23 is provided on the side wall of the mounting cavity 14 of the cup lid body 1. The vent plug 23 has a vent hole 24 that connects the inside and outside of the cup lid body 1.

[0033] In its natural state, under the action of the torsion spring 16, the plug 22 of the rotary switch 15 always elastically presses against the vent hole 24 of the vent plug 23. The button 11 and the movable switch 5 are not completely aligned. A limiting rib 25 is also provided on one side of the sliding groove 4 at the front end of the cup lid body 1. In its natural state, the rear end of the button 11 abuts against the front side of the limiting rib 25. Rotating the outer ring 9 causes the inner teeth 21 of the outer ring 9 to drive the rotary switch 15 to rotate, so that the plug 22 of the rotary switch 15 gradually moves away from the vent hole 24. At the same time, the button 11 gradually aligns completely with the movable switch 5. Pressing the button 11 inward pushes the movable switch 5 backward, causing the first engaging part of the movable switch 5 to disengage from the second engaging part of the flip cover 2.

[0034] The cup lid body 1 includes an inner fastener 26 and a connecting body 27, which are fixedly fitted together. The inner fastener 26 and the connecting body 27 can be fixedly connected by snap-fit. The top center of the inner fastener 26 has an upwardly protruding mounting boss 28. The top plate of the connecting body 27 has a through hole 29. The mounting boss 28 of the inner fastener 26 fits into the through hole 29 of the connecting body 27. A suction nozzle 30 is provided on the mounting boss 28 of the inner fastener 26. The inside of the cup lid is connected through the internal channel of the suction nozzle 30. The lower end of the suction nozzle 30 extends below the mounting boss 28 of the inner fastener 26 and is fitted with a straw 31. The bottom of the inner fastener 26 has a lower limiting flange 32, and the top of the connecting body 27 has an upper limiting flange 33. The outer wall of the connecting body 27, the upper limiting flange 33, and the lower limiting flange 32 together form an annular mounting groove for positioning and installing the outer ring 9, so that the outer ring 9 can only rotate circumferentially and cannot move axially.

[0035] The slide groove 4 and the mounting cavity 14 are respectively provided on the connecting body 27. The top of the connecting body 27 has an insertion hole 34 that communicates with the slide groove 4. The second engaging part of the flip cover 2 includes an engaging rib 35 provided on the inner side of the flip cover 2. The lower section of the engaging rib 35 has an engaging groove 36. The first engaging part of the movable switch 5 is an engaging protrusion 37. When the flip cover 2 is closed, the engaging rib 35 of the flip cover 2 is inserted downward from the insertion hole 34 of the connecting body 27 into the slide groove 4 and engages with the engaging protrusion 37 of the movable switch 5. In order to facilitate the installation of the internal components of the mounting cavity 14, the top end of the mounting cavity 14 of the connecting body 27 is set as an open end, and the open end of the top of the mounting cavity 14 is covered by a cover plate 38. The cover plate 38 can be connected to the connecting body 27 by a snap-fit.

[0036] Both the inner fastener 26 and the connector 27 have vent plug 23 mounting holes at the corresponding locations of the vent plug 23 for installing the vent plug 23. The vent plug 23 mounting holes connect the inside and outside of the cup lid body 1.

[0037] This embodiment also discloses a flip-top cup with linked opening, self-locking, and anti-splash functions, including a cup body 39 and the aforementioned flip-top cup lid. The flip-top cup lid and the cup body 39 can be connected by a threaded connection, and the opening of the cup body 39 is sealed by a sealing ring 40 provided on the inner fastener 26 of the flip-top cup lid.

[0038] When the flip cover 2 of the flip cup lid is closed, the first engaging part of the movable switch 5 engages with the second engaging part of the flip cover 2. Under the action of the torsion spring 16, the plug 22 of the rotary switch 15 always elastically presses against the vent hole 24 of the vent plug 23. The button 11 does not completely correspond to the movable switch 5. One end of the button 11 abuts against the front side of the limiting rib 25. At this time, the button 11 cannot be pressed and the button 11 is in a locked state.

[0039] When the flip cover 2 needs to be opened, the operator holds the cup body 39 with their hand, and gently presses the button 11 with their thumb. Since the button 11 is locked, it cannot be pressed. The operator uses the right side of their thumb to press the actuating protrusion 13 on the outer ring 9, rotating the outer ring 9 counterclockwise by a certain angle until it reaches its limit position. As the outer ring 9 rotates counterclockwise, the inner teeth 21 of the outer ring 9 mesh with the outer teeth 20 of the rotary switch 15, causing the outer ring 9 to drive the rotary switch 15 to rotate counterclockwise around the mounting shaft 17. This causes the plug 22 of the rotary switch 15 to gradually move away from the vent hole 24 of the vent plug 23, thereby releasing the blockage of the vent plug 23 and achieving venting and pressure relief. Simultaneously, as the outer ring 9 rotates counterclockwise, the button 11 rotates with it. When the outer ring 9 rotates counterclockwise to its limit position, the button 11 rotates to face forward and is opposite the movable switch 5. At this point, the button 11 disengages from the limiting rib 25, the button 11 is unlocked, and the lock is released. Keeping the outer ring 9 stationary, press button 11 inward. Button 11 pushes the movable switch 5 backward, causing the first engaging part of the movable switch 5 to disengage from the second engaging part of the flip cover 2. The flip cover 2 automatically opens under the elastic force of the suction nozzle 30, thus opening the flip cover 2. Then release the thumb from pressing button 11. At this time, the movable switch 5 moves forward to reset under the elastic force of the return spring 6. Release the thumb from the contact of the thumb with the actuating protrusion 13 on the outer ring 9. The outer ring 9 is completely released. At this time, under the elastic force of the torsion spring 16, the rotary switch 15 rotates in the opposite direction to reset until the plug 22 of the rotary switch 15 presses against the vent hole 24 of the vent plug 23. At the same time, the rotary switch 15 drives the outer ring 9 to rotate in the opposite direction to reset, thereby driving the button 11 on the outer ring 9 to reset and lock the button 11 again.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
