Description

Technical Field

[0001] This utility model relates to a cup lid, and more particularly to a rotating double-drinking cup lid. Background Technology

[0002] Water cups are the most common items in human life, but everyone has different preferences for drinking water. Some people drink water with straws, while others drink directly from the cup. When people only have one water cup and want to enjoy different ways of drinking water, they need to use different lids, which can be inconvenient.

[0003] To address the aforementioned issues, cup lids with two drinking structures have emerged on the market. For example, patent CN217488217U discloses a dual-drinking cup lid and cup, comprising a lid body, a pressing part, and a locking part. The lid body has a direct drinking spout and a sipping spout, both of which are permeated through the upper surface of the lid body. The pressing part has a first pressing mechanism and a second pressing mechanism, both of which are rotatably connected to the lid body. The first pressing mechanism is positioned above the direct drinking spout for opening and closing it; the second pressing mechanism is positioned above the sipping spout for opening and closing it. The locking part has a flip-type locking ring mechanism and a press-type locking mechanism. The flip-type locking ring mechanism is rotatably connected to the lid body and, by flipping, locks the pressing part vertically. The press-type locking mechanism is fitted into the lid body and, by extending laterally, locks the pressing part horizontally. The dual-drink lid offers two different drinking methods: direct drinking and sipping, providing a wide range of choices and adaptability to various scenarios. Furthermore, the double locking mechanism, both horizontally and vertically, ensures a tighter seal, preventing spills.

[0004] Existing dual-drink cup lids have a direct drinking spout and a sippy spout distributed on the left and right sides of the lid body, and the two flip-tops on the left and right sides are used to close the direct drinking spout and the sippy spout respectively. The two flip-tops require independent locking mechanisms to lock with the cup lid, which increases the complexity of the cup lid locking structure. Furthermore, when drinking directly or sipping, the other flip-top that is not opened will obstruct the user's drinking and affect the comfort of drinking. Utility Model Content

[0005] Based on the above-mentioned problems of setting a direct drinking spout and a sippy spout distributed on the left and right sides of the lid, and using two flip-tops to close the direct drinking spout and the sippy spout respectively, the two flip-tops require independent locking mechanisms to lock with the lid, which increases the complexity of the lid locking structure. Furthermore, when drinking directly or sipping, the other flip-top that is not opened will obstruct the user's drinking and affect the comfort of drinking. Therefore, this utility model provides a rotating dual-drinking cup lid.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a rotating double-drinking cup lid, including a lid body and a flip lid. The lid body includes an upper lid body and a lower lid body. A rotating groove is provided on the top of the lower lid body, and a turntable is protruding in the rotating groove. A rotating slot is provided on the bottom of the upper lid body. The upper lid body is inserted into the rotating groove and the turntable is inserted into the rotating slot, so that the upper lid body is rotatably mounted on the lower lid body. A ring of limiting ribs is protruding on the inner wall of the rotating slot, and a sliding groove is formed between the limiting ribs and the inner top wall of the rotating slot. A sliding rib is protruding on the outer circumference of the turntable, and the sliding rib is slidably mounted in the sliding groove. The limiting ribs are provided with notches for the sliding ribs to enter and exit the sliding groove. The lower lid body is provided with a drinking channel and a direct drinking channel. Both the drinking channel and the outlet of the direct drinking channel are located on the top of the turntable. A first sealing gasket is fixed on the top of the turntable. The first sealing gasket has a first through hole and a second through hole. The first through hole and the second through hole are respectively connected to the outlet of the drinking channel and the direct drinking channel. The first sealing gasket is fitted against the inner top wall of the rotating slot. The upper cover is provided with a drinking channel. The inlet of the drinking channel is located on the inner top wall of the rotating slot, and the outlet of the drinking channel is located on the top of the upper cover. One side of the flip cover is hinged to the upper cover, and the other side of the flip cover is connected to the upper cover through a locking mechanism. The flip cover is closed on the upper cover. By rotating the upper cover, the inlet of the drinking channel is switched between the position connected to the first through hole and the position connected to the second through hole.

[0007] A further preferred technical solution of this utility model is as follows: the rotating groove is provided with limiting blocks on both sides of the turntable, and the bottom of the upper cover is provided with a protrusion that moves between the limiting blocks on both sides.

[0008] A further preferred technical solution of this utility model is as follows: a locking protrusion is provided on one side of the limiting block in the rotating groove. There is a distance between the locking protrusion and the limiting block, and a locking area is formed between the locking protrusion and the limiting block. The protrusion can enter or move out of the locking area through elastic deformation between the two after being squeezed with the locking protrusion. When the upper cover rotates relative to the lower cover until the protrusion is locked in the locking area on one side, the channel inlet of the drinking channel is connected to the first through hole. When the upper cover rotates relative to the lower cover until the protrusion is locked in the locking area on the other side, the channel inlet of the drinking channel is connected to the second through hole.

[0009] A further preferred technical solution of this utility model is as follows: the limiting rib is provided with two notches, namely the first notch and the second notch, which divide the limiting rib into two paths. The two limiting ribs are arranged opposite to each other on both sides of the inner groove wall of the rotating slot. Sliding ribs are provided on both sides of the outer circumferential surface of the turntable. The two sliding ribs include the first sliding rib and the second sliding rib corresponding to the first notch and the second notch, respectively. The length of the first notch is greater than or equal to the length of the first sliding rib, which is greater than or equal to the length of the second notch.

[0010] A further preferred embodiment of this utility model is as follows: the bottom edge of the upper cover is provided with a plurality of support protrusions, which are used to contact and support the inner bottom of the rotating groove.

[0011] A further preferred technical solution of this utility model is as follows: the upper cover is provided with an air hole, the air inlet of the air hole is located on the inner top wall of the rotating slot, and the air outlet of the air hole is located on the top of the upper cover. When the upper cover rotates to the position where the inlet of the drinking channel is connected to the first through hole, the air inlet of the air hole is connected to the second through hole. When the upper cover rotates to the position where the inlet of the drinking channel is connected to the second through hole, the air inlet of the air hole is connected to the first through hole.

[0012] A further preferred technical solution of this utility model is as follows: the flip cover is provided with a first sealing plug and a second sealing plug. When the flip cover is closed on the upper cover, the first sealing plug and the second sealing plug respectively block the air outlet of the air hole and the channel outlet of the drinking water channel.

[0013] A further preferred technical solution of this utility model is as follows: the locking mechanism includes a button lock and a return spring. The button lock is movably disposed on the side of the upper cover. The button lock is provided with a snap-fit ​​part. The flip cover is provided with a snap-fit ​​groove. The snap-fit ​​part snaps into the snap-fit ​​groove. Pressing the button lock can cause the snap-fit ​​part to disengage from the snap-fit ​​groove. A torsion spring is provided between the flip cover and the upper cover. The torsion spring is used to drive the flip cover to flip upward when the snap-fit ​​part disengages from the snap-fit ​​groove.

[0014] A further preferred technical solution of this utility model is: a handle ring is hinged to the upper cover, the handle ring can be flipped down or stood up, and when the handle ring is flipped down, the handle ring wraps around the outside of the upper cover and blocks the button lock.

[0015] A further preferred embodiment of this utility model is as follows: a mark is provided on the side wall of the front side of the upper cover, and a recess is provided on the side walls of the front and rear sides of the rotating groove, the recess being used to expose the mark.

[0016] Compared with the prior art, the advantage of this utility model is that the upper cover is rotatably mounted on the lower cover. The upper cover has a drinking channel, and the lower cover has a drinking channel and a direct drinking channel. By rotating the upper cover, the drinking channel can be switched between being connected to the drinking channel and the direct drinking channel, thereby switching the drinking method. Different drinking methods are all done through the same drinking channel on the upper cover, so that the entire cup lid only needs one flip cover and one locking mechanism, simplifying the product structure. Moreover, when drinking, it will not obstruct the connection between the user's mouth and the outlet of the drinking channel, thus improving drinking comfort.

[0017] The rotation of the upper and lower covers is achieved by the upper cover being inserted into a rotating groove on the top of the lower cover, and the turntable within the rotating groove being inserted into a rotating slot at the bottom of the upper cover. This ensures rotational stability. The outlets of both the drinking and direct drinking channels are located on the top of the turntable. A first sealing gasket is fixed to the top of the turntable, with a first through hole and a second through hole. The first and second through holes connect to the outlets of the drinking and direct drinking channels, respectively. The first sealing gasket is fitted against the inner top wall of the rotating slot, and the inlet of the drinking channel is located on the inner top wall of the rotating slot. When the drinking and drinking channels are connected, or when they are connected, the first sealing gasket prevents liquid from overflowing from the gaps between the first sealing gasket and the turntable, and between the first sealing gasket and the inner top wall of the rotating slot, maintaining a sealed connection between the channels.

[0018] The connection between the upper and lower lids is restricted by the cooperation of sliding ribs and limiting ribs. By adjusting the sliding ribs to an angle position opposite to the notch, the upper and lower lids can be assembled and disassembled, thereby achieving thorough cleaning of the dead corners inside the lid and ensuring hygiene and health.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] Figures 1-12As shown, the rotating double-drinking cup lid includes a lid body and a flip-top 1. The lid body includes an upper lid body 2 and a lower lid body 5. The top of the lower lid body 5 has a rotating groove 20, and a turntable 25 protrudes from the rotating groove 20. The bottom of the upper lid body 2 has a rotating slot 19. The upper lid body 2 is inserted into the rotating groove 20 and the turntable 25 is inserted into the rotating slot 19, so that the upper lid body 2 is rotatably mounted on the lower lid body 5. A ring of limiting ribs 29 protrudes from the inner wall of the rotating slot 19, and a sliding groove 32 is formed between the limiting ribs 29 and the inner top wall of the rotating slot 19. A sliding rib protrudes from the outer circumference of the turntable 25, and the sliding rib is slidably mounted in the sliding groove 32 to restrict the separation of the upper lid body 2 and the lower lid body 5. The limiting ribs 29 have notches for the sliding ribs to enter and exit the sliding groove 32. The lower lid body 5 has a drinking channel 18 and a direct drinking channel 16. The drinking channel 18 and the direct drinking channel 16 are connected... The outlets of the channels all fall on the top of the turntable 25. A first sealing gasket 24 is fixed on the top of the turntable 25. The first sealing gasket 24 has a first through hole 22 and a second through hole 23. The first through hole 22 and the second through hole 23 are respectively connected to the channel outlets of the drinking channel 18 and the direct drinking channel 16. The first sealing gasket 24 is fitted against the inner top wall of the rotating slot 19. The upper cover 2 is provided with a drinking channel 13. The channel inlet of the drinking channel 13 is located on the inner top wall of the rotating slot 19, and the channel outlet of the drinking channel 13 is located on the top of the upper cover 2. One side of the flip cover 1 is hinged to the upper cover 2, and the other side of the flip cover 1 is connected to the upper cover 2 through a locking mechanism. The flip cover 1 is closed on the upper cover 2 to cover the top of the upper cover 2. By rotating the upper cover 2, the channel inlet of the drinking channel 13 is switched between the position connected to the first through hole 22 and the position connected to the second through hole 23.

[0025] Figure 4 , Figure 8 As shown, the top of the upper cover 2 is provided with an upward protruding drinking spout 11, and the channel outlet of the drinking channel 13 is located on the upper end of the drinking spout 11 for the user to drink.

[0026] Figure 9 , Figure 10 As shown, the first sealing gasket 24 is a soft gasket made of silicone or rubber. A groove 42 is provided on the top surface of the turntable 25, and the first sealing gasket is embedded in the groove 42. A connecting rib 41 protrudes from the bottom of the groove 42, and a connecting groove is provided on the bottom of the first sealing gasket 24. The connecting rib 41 is inserted into the connecting groove to fix the first sealing gasket 24 to the top of the turntable 25. The outlets of the drinking channel 18 and the direct drinking channel 16 are located on the bottom of the groove 42. Additionally, two protruding nozzles 40 are provided in the groove 42, and the outlets of the drinking channel 18 and the direct drinking channel 16 are located on the two protruding nozzles 40. The two protruding nozzles 40 are respectively inserted into the first through hole 22 and the second through hole 23 to improve the sealing connection between the first through hole 22, the second through hole 23 and the outlets of the drinking channel 18 and the direct drinking channel 16.

[0027] The bottom of the lower cover 5 is provided with a downward protruding connecting tube 17, and the channel inlet of the drinking channel 18 is located on the lower end of the connecting tube 17. The connecting tube 17 is used to connect with the straw.

[0028] The bottom inner side of the upper cover 2 is provided with a downward protruding sleeve 31, and the inner side of the sleeve 31 forms the aforementioned rotating slot 19.

[0029] This patent rotatably mounts the upper cover 2 onto the lower cover 5. The upper cover 2 has a drinking channel 13, while the lower cover 5 has a drinking channel 18 and a direct drinking channel 16. By rotating the upper cover 2, the drinking channel 13 can switch between being connected to the drinking channel 18 and the direct drinking channel 16, thus enabling switching of drinking methods. Different drinking methods all involve drinking through the same drinking channel 13 on the upper cover 2. This simplifies the product structure by requiring only one flip cover 1 and one locking mechanism. Furthermore, it does not obstruct the connection between the user's mouth and the outlet of the drinking channel 13 during drinking, improving drinking comfort.

[0030] The rotation of the upper cover 2 and the lower cover 5 is achieved by the upper cover 2 being inserted into the rotating groove 20 at the top of the lower cover 5, and the turntable 25 in the rotating groove 20 being inserted into the rotating slot 19 at the bottom of the upper cover 2. During rotation, the built-in upper cover 2 and the connected turntable 25 and rotating slot 19 can maintain rotational stability. The outlets of the drinking channel 18 and the direct drinking channel 16 are both located on the top of the turntable 25. A first sealing gasket 24 is fixed on the top of the turntable 25. A first through hole 22 and a second through hole 23 are formed on the first sealing gasket 24. 2. The second through hole 23 is connected to the channel outlets of the drinking channel 18 and the direct drinking channel 16, respectively. The first sealing gasket 24 is fitted against the inner top wall of the rotating slot 19, and the channel inlet of the drinking channel 13 is located on the inner top wall of the rotating slot 19. When the drinking channel 13 is connected to the drinking channel 18 or the drinking channel 13 is connected to the direct drinking channel 16, the first sealing gasket 24 can prevent liquid from overflowing from the gap between the first sealing gasket 24 and the turntable 25 and the gap between the first sealing gasket 24 and the inner top wall of the rotating slot 19, thus maintaining the sealed connection between the channels.

[0031] The connection between the upper cover 2 and the lower cover 5 is restricted by the cooperation of the sliding rib and the limiting rib 29. By adjusting the sliding rib to the angle position opposite to the notch, the upper cover 2 and the lower cover 5 can be assembled and disassembled, thereby achieving a thorough cleaning of the dead corners inside the cup lid and ensuring hygiene and health.

[0032] Figures 7-9As shown, the rotating groove 20 is provided with limiting blocks 36 on both sides of the turntable 25. The bottom of the upper cover 2 is provided with a protrusion 28 that moves between the limiting blocks 36 on both sides. The protrusion 28 moves between the limiting blocks 36 on both sides to limit the angle range of the upper cover 2 relative to the lower cover 5.

[0033] A locking protrusion 38 is provided on one side of the limiting block 36 within the rotating groove 20. There is a gap between the locking protrusion 38 and the limiting block 36, and a locking area 37 is formed between the locking protrusion 38 and the limiting block 36. The protrusion 28 can enter or move out of the locking area 37 through elastic deformation between the two after being squeezed with the locking protrusion 38, so as to lock the rotation of the upper cover 2 relative to the lower cover 5 and keep the upper cover 2 in the angular position.

[0034] When the upper cover 2 rotates relative to the lower cover 5 until the protrusion 28 is engaged in the locking area 37 on one side, the inlet of the drinking channel 13 is connected to the first through hole 22. At this time, the drinking channel 18 is connected to the drinking channel 13, locking the upper cover 2 in the drinking state, and the user can drink through the drinking channel 13. When the upper cover 2 rotates relative to the lower cover 5 until the protrusion 28 is engaged in the locking area 37 on the other side, the inlet of the drinking channel 13 is connected to the second through hole 23. At this time, the direct drinking channel 16 is connected to the drinking channel 13, locking the upper cover 2 in the direct drinking state, and the user can drink directly through the drinking channel 13.

[0035] The upper cover 2 and the lower cover 5 can be made of plastic. The plastic itself has a certain elasticity. When the upper cover 2 rotates and the protrusion 28 is pressed against the locking protrusion 38, the protrusion 28 and the locking protrusion 38 can undergo elastic deformation so that the protrusion 28 can pass over the locking protrusion 38, thereby allowing the protrusion 28 to be inserted into or removed from the locking area 37.

[0036] The limiting rib 29 has two notches, namely the first notch 30 and the second notch 26. The two notches divide the limiting rib 29 into two sections. The two limiting ribs 29 are arranged opposite each other on both sides of the inner groove wall of the rotating slot 19. Sliding ribs are provided on both sides of the outer circumference of the turntable 25. The two sliding ribs include the first sliding rib 35 and the second sliding rib 39 corresponding to the first notch 30 and the second notch 26, respectively. The length of the first notch 30 is greater than or equal to the length of the first sliding rib 35, which is greater than or equal to the length of the second notch 26. This ensures that the first sliding rib 35 can only enter and exit the slide groove 32 through the first notch 30. The turntable 25 can only be properly inserted into the rotating slot 19 when the first sliding rib 35 is opposite to the first notch 30. This serves as a foolproof method to prevent the upper cover 2 from being installed on the lower cover 5 in the wrong direction.

[0037] During assembly, the first sliding rib 35 is aligned with the first notch 30, and the second sliding rib 39 is aligned with the second notch 26. At this time, the upper cover 2 is pressed into the rotating groove 20 so that the turntable 25 is inserted into the rotating slot 19. When the upper cover 2 is pressed until there is no extra gap between it and the lower cover 5, the upper cover 2 can be rotated to switch the drinking mode.

[0038] Preferably, the outlets of the drinking channel 18 and the direct drinking channel 16 are located on both sides of the rotation center line of the upper cover 2, so that when the upper cover 2 rotates 180°, the drinking channel 13 can change from the position connected to the first through hole 22 to the position connected to the second through hole 23.

[0039] Figure 5 , Figure 6 As shown, with the drinking channel 13 connected to the first through hole 22, the first sliding rib 35 and the second sliding rib 39 are respectively located in the sliding grooves 32 on both sides. When the upper cover 2 is rotated 90° counterclockwise, the first notch 30 rotates to the position opposite to the first sliding rib 35, and the second notch 26 rotates to the position opposite to the second sliding rib 39. The upper cover 2 and the lower cover 5 can then be separated from each other. When the upper cover 2 is rotated 90° counterclockwise again at this position, the drinking channel 13 is connected to the second through hole 23, and the two limiting ribs 29 rotate to the positions below the first sliding rib 35 and the second sliding rib 39, respectively.

[0040] The bottom edge of the upper cover 2 is provided with several support protrusions 27. The support protrusions 27 are used to contact and support the inner bottom of the rotating groove 20 to reduce the friction when the upper cover 2 and the lower cover 5 rotate.

[0041] Figure 1 , Figure 9 As shown, a mark 3 is provided on the side wall of the front side of the upper cover 2, and a recess 4 is provided on the side walls of the front and rear sides of the rotating groove 20. The recess 4 is used to expose the mark 3. By setting the mark 3 and the recess 4, the front and rear direction of the upper cover 2 can be determined, and the wrong direction can be prevented from being installed.

[0042] The upper cover 2 is provided with an air hole 14. The air inlet of the air hole 14 is located on the inner top wall of the rotating slot 19, and the air outlet of the air hole 14 is located on the top of the upper cover 2. When the upper cover 2 is rotated to the position where the inlet of the drinking channel 13 is connected to the first through hole 22, the air inlet of the air hole 14 is connected to the second through hole 23, so that air can be replenished through the connection between the air hole 14 and the direct drinking channel 16 in the drinking state to balance the pressure inside the cup. When the upper cover 2 is rotated to the position where the inlet of the drinking channel 13 is connected to the second through hole 23, the air inlet of the air hole 14 is connected to the first through hole 22.

[0043] The flip cover 1 is provided with a first sealing plug 15 and a second sealing plug 10. When the flip cover 1 is closed on the upper cover 2, the first sealing plug 15 and the second sealing plug 10 respectively block the air outlet of the air hole 14 and the channel outlet of the drinking channel 13. The first sealing plug 15 and the second sealing plug 10 are both set on the same silicone part, which is fixed inside the flip cover 1.

[0044] Figure 5 As shown, the locking mechanism includes a button lock 7 and a return spring 21. The button lock 7 is movably disposed on the side of the upper cover 2. The button lock 7 is provided with a latching part 12, and the flip cover 1 is provided with a latching groove 9. The latching part 12 is latched onto the latching groove 9. Pressing the button lock 7 can cause the latching part 12 to disengage from the latching groove 9. A torsion spring is provided between the flip cover 1 and the upper cover 2. The torsion spring is used to drive the flip cover 1 to flip up when the latching part 12 disengages from the latching groove 9, so as to achieve the effect of unlocking the flip cover without having to open the flip cover 1 by hand.

[0045] Figure 8 , Figure 12 As shown, a button groove 33 is provided on the side wall of the upper cover 2, and guide grooves 34 are provided on both sides of the button groove 33. Guide blocks 43 are protruding on both sides of the button lock 7. The guide blocks 43 can be inserted into the guide grooves 34 through elastic deformation. When the button lock 7 is pressed, the guide blocks 43 can slide along the guide grooves 34 to restrict the button lock 7 to move in a straight line.

[0046] The inner side of the button lock 7 is provided with a spring groove 44. One end of the reset spring 21 is inserted into the spring groove 44, and the other end of the reset spring 21 abuts against the inner wall of the button groove 33 to drive the button lock 7 to move outward and reset.

[0047] Figure 1 , Figure 3 , Figure 5 As shown, a handle ring 6 is hinged to the upper cover 2. The handle ring 6 can be flipped down or stood up. When the handle ring 6 is flipped down, it wraps around the outside of the upper cover 2 and blocks the button lock 7 to prevent accidental activation of the button lock 7 to open the flip cover 1. When the handle ring 6 is stood up, it serves as a handle for hand lifting.

[0048] Figure 2 , Figure 11As shown, the button lock 7 protrudes slightly from the button groove 33. The inner side of the handle ring 6 is provided with a corresponding clearance groove 8 for the button lock 7. The clearance groove 8 is open at the top and has a side wall at the bottom. When the handle ring 6 is flipped over, the button lock 7 is locked into the clearance groove 8, which can prevent the handle ring 6 from automatically flipping upward. When the flip cover 1 is closed on the upper cover 2 and the snap-fit ​​part 12 on the button lock 7 is engaged with the snap groove 9 to lock the flip cover 1, the handle ring 6 is flipped down. During the process of the handle ring 6 being flipped down by external force, the lower edge of the handle ring 6 presses the button lock 7 inward along the outer surface of the button lock 7, so that the handle ring 6 can pass down from the outside of the button lock 7 until the handle ring 6 is flipped down to the position where the clearance groove 8 is opposite to the button lock 7. The button lock 7 is pushed outward into the clearance groove 8 by the return spring 21.
