Description
Technical Field
[0001] This utility model relates to a cup lid, and more particularly to a cup lid with a liftable spout. Background Technology
[0002] Water bottles are a common drinking utensil in daily life, and many people use them to carry drinking water when they go out. To make drinking easier, many water bottles nowadays have a drinking spout, which allows people to drink water by inverting the bottle and using the spout.
[0003] For example, the sports water bottle disclosed in patent CN201557712U includes a bottle body and a spout. The spout also includes an anti-splash device, which includes an anti-splash rubber ring and a fixing device for fixing the anti-splash rubber ring to the spout. The anti-splash rubber ring has a slit, which opens when squeezed by the pressure inside the bottle body, allowing water inside the bottle to flow out from the spout.
[0004] The existing direct-drinking sports water bottles have the following problems: they use a slit in the anti-splash rubber ring for water dispensing. Under normal conditions, the slit needs to be sealed by the two sides. When a pressure difference occurs inside and outside the bottle, the two sides of the slit can be squeezed open to open the slit. This type of slit structure requires the two sides of the slit to be sealed by its own elasticity. However, the slit inside the spout is usually made by opening a slit in a thin film. The film itself is relatively soft, and it cannot guarantee that the slit will be completely sealed when not drinking. Furthermore, after long-term compression, the two sides of the slit will deform and not recover, making the slit structure not have a very stable water sealing effect. Utility Model Content
[0005] Based on the above-mentioned problem that water can be dispensed and sealed through a slit, but the slit structure does not have a very stable water sealing effect, this utility model provides a lifting spout cup lid.

[0040] 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.
[0041] 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.
[0042] Figures 1-14 As shown, the lifting spout cup lid includes a lid body and a drinking component 36 disposed on the lid body. The lid body can be connected to a container holding liquid, and the container communicates with the inner side of the lid body. The lid body has a lifting channel 25 communicating with the inner side of the lid body, allowing liquid in the container to enter the lifting channel 25 from the inside of the lid body. The drinking component 36 includes a drinking spout 17 and a flexible connector. The drinking spout 17 has a drinking channel 4 inside, and the drinking spout 17 is inserted into the lifting channel 25 and can move up and down along the lifting channel 25. The top of the lid body has a top opening 5 for the upper end of the drinking spout 17 to extend out. The flexible connector is fixed to the lid body and is spaced between the inner walls of the drinking spout 17 and the lifting channel 25. Both the inner walls of the drinking spout 17 and the lifting channel 25 are made of rigid material. The drinking channel 4 inside the drinking spout 17 extends through the end faces of both ends of the drinking spout 17.
[0043] Figure 4 , Figure 6 As shown, when the drinking spout 17 is lowered to the low position, the flexible connector closes the drinking channel 4 on the drinking spout 17. At this time, the liquid in the container cannot enter the drinking channel 4 of the drinking spout 17 through the lifting channel 25. When the drinking spout 17 is raised to the high position, the drinking channel 4 on the drinking spout 17 opens. At this time, the container with the lid can be inverted so that the lid is facing down. The liquid in the container flows downward into the inside of the lid and then enters the lifting channel 25 from the inside of the lid. The liquid entering the lifting channel 25 can flow out from the drinking channel 4 for the user to drink directly. The lifting and lowering movement of the drinking spout 17 can be controlled by pulling it up or pressing it down.
[0044] A lifting channel 25 is provided on the cover, and a drinking spout 17 is inserted into the lifting channel 25. A flexible connector is provided between the drinking spout 17 and the inner wall of the lifting channel 25. When the drinking spout 17 moves down to the low position, the flexible connector closes the drinking channel 4 on the drinking spout 17. When the drinking spout 17 moves up to the high position, the drinking channel 4 on the drinking spout 17 opens, and the liquid entering the lifting channel 25 can flow out from the drinking channel 4 for direct drinking. The opening and closing of the drinking channel 4 is controlled by the lifting and moving of the drinking spout 17, which is simple and convenient to operate.
[0045] A flexible connector is sandwiched between the drinking spout 17 and the inner wall of the lifting channel 25. The flexible connector acts as a sealant to close the gap between the drinking spout 17 and the lifting channel 25. When the drinking spout 17 moves down to a low position, the flexible connector closes the drinking channel 4 to achieve a better sealing effect. The inner walls of the drinking spout 17 and the lifting channel 25 are made of rigid material. The rigid inner walls of the drinking spout 17 and the lifting channel 25 support the inner and outer sides of the flexible connector to prevent the flexible connector from being squeezed, bent and deformed when the drinking spout 17 moves up and down, thus maintaining a stable water sealing effect.
[0046] Figure 3 , Figure 4 , Figure 10 , Figure 11 As shown, the cover includes an outer cover 1 and a detachable inner cover 7 installed inside the outer cover 1. The inner cover 7 is provided with a lifting channel 25 with an upper opening. The top of the outer cover 1 is provided with a top opening 5 opposite to the opening of the lifting channel 25. The soft connector includes a sleeve 24 with an upper opening and a connecting seat fixed to the upper end of the sleeve 24. The connecting seat is clamped and fixed between the inner cover 7 and the outer cover 1. The sleeve 24 is inserted into the lifting channel 25. The drinking spout 17 is movably inserted into the sleeve 24 and its upper end extends out of the outer cover 1 from the top opening 5. The outer wall of the sleeve 24 fits against the inner wall of the lifting channel 25. The outer wall of the drinking spout 17 fits against the inner wall of the sleeve 24. A water inlet 11 is provided below the inner wall of the lifting channel 25. A through-hole 26 opposite to the water inlet 11 is provided on the side wall of the sleeve 24.
[0047] When the drinking spout 17 is lowered to the low position, the bottom of the sleeve 24 blocks the opening of the drinking channel 4 at the lower end of the drinking spout 17. At this time, the liquid in the container cannot enter through the opening of the drinking channel 4 at the lower end of the drinking spout 17, so that the liquid cannot flow out. When the drinking spout 17 is raised to the high position, the opening at the lower end of the drinking spout 17 is away from the bottom of the sleeve 24, so that the opening at the lower end of the drinking spout 17 is open and connected to the water inlet 11. When the container is inverted for drinking, the water in the container can flow into the inside of the cup body, and enter the lower part of the sleeve 24 through the water inlet 11 and the opening 26. Then it enters through the opening of the drinking channel 4 at the lower end of the drinking spout 17, and flows out after passing through the drinking channel 4 for direct drinking.
[0048] The sleeve 24 is tightly inserted into the lifting channel 25, and the drinking spout 17 is tightly inserted into the sleeve 24.
[0049] The inner cover 7 and the outer cover 1 are designed to be detachable, allowing the inner cover 7 and the outer cover 1 to be separated, and the soft connector and the drinking spout 17 to be removed, so that the inner cover 7, the outer cover 1, the soft connector and the drinking spout 17 can all be disassembled and cleaned.
[0050] The bottom of the sleeve 24 is provided with a first protrusion 29 for sealing. When the drinking spout 17 is moved to a low position, the first protrusion 29 is inserted into the opening of the drinking channel 4 located at the lower end of the drinking spout 17 to seal the opening at the lower end of the drinking channel 4. The insertion-type sealing method achieves better sealing.
[0051] The outer wall of the drinking spout 17 is provided with a limiting protrusion 28 corresponding to the opening 26. The limiting protrusion 28 is engaged in the opening 26 to prevent the drinking spout 17 from detaching from the sleeve 24. The limiting protrusion 28 moves up and down in the opening 26 as the drinking spout 17 moves up and down in the sleeve 24. When the drinking spout 17 moves up to the point where the top surface of the limiting protrusion 28 abuts against the upper inner wall of the opening 26, it prevents the drinking spout 17 from moving further upward. The top surface of the limiting protrusion 28 can be made into a plane to achieve a better limiting effect.
[0052] Figures 4-6 , Figure 14 As shown, the outer wall of the drinking spout 17 has a protruding locking part 27, and the inner wall of the sleeve 24 has a recessed locking groove 33. When the drinking spout 17 moves down to the low position, the locking part 27 is engaged below the upper inner wall of the opening 26 to restrict the movement of the drinking spout 17 relative to the sleeve 24, so that the drinking spout 17 is locked in the low position and maintains the stability of the seal; when the drinking spout 17 moves up to the high position, the locking part 27 falls into the locking groove 33 to restrict the movement of the drinking spout 17 relative to the sleeve 24, so that the drinking spout 17 is locked in the high position, so that there is no need to hold the position of the drinking spout 17 by hand when drinking water.
[0053] During the process of the drinking spout 17 moving from a lower position to a higher position under force, or during the process of the drinking spout 17 moving from a higher position to a lower position under force, the locking part 27 compresses the sleeve 24, causing the sleeve 24 to undergo elastic deformation. This allows the locking part 27 to move and change between the position below the upper inner wall of the opening 26 and the position opposite to the locking groove 33. The cross-section of the locking part 27 can be a semi-circular surface to facilitate the deformation of the sleeve 24.
[0054] When the inner cover 7 and the outer cover 1 are disassembled, the drinking component 36 is removed from between the inner cover 7 and the outer cover 1. Since the soft connector is soft, the drinking spout 17 is pulled out from the sleeve 24 by applying force to make the sleeve 24 elastically deform, thus completing the disassembly of each component.
[0055] Figures 7-9 , Figure 12 , Figure 13 As shown, the inner cover 7 includes a sleeve 13 and a pressure plate 14 fixed to the upper end of the sleeve 13. The sleeve 13 is provided with a lifting channel 25. The top of the pressure plate 14 is provided with an upwardly protruding upper ring edge 30. The upper ring edge 30 is provided with a snap-fit protrusion 31. The inner top surface of the outer cover 1 is provided with multiple downwardly protruding lower protruding edges 34. The lower protruding edges 34 form a ring to form a slot 35 inside. A buckle 32 is provided between two lower protruding edges 34. The upper ring edge 30 is inserted into the slot 35 and the buckle 32 is snapped with the snap-fit protrusion 31. The opening at the upper end of the lifting channel 25 is located inside the upper ring edge 30. The connecting seat includes an upper seat body 2 and a lower seat body 19. The upper seat body 2 and the lower seat body 19 are connected by a step. The lower seat body 19 is inserted into the upper ring edge 30 and sandwiched between the inner top surface of the outer cover 1 and the pressure plate 14. The upper seat body 2 is inserted into the top opening 5 of the outer cover 1.
[0056] By setting an upper ring edge 30 on the top of the pressure plate 14, it is convenient to install the soft connector. The lower seat 19 is inserted into the upper ring edge 30 to position the soft connector and the inner cover 7. Then, the inner cover 7 is pressed upward on the inner top surface of the outer cover 1 to complete the assembly.
[0057] Preferably, the inner top surface of the outer cover 1 is provided with two arc-shaped lower protruding edges 34, which form the slot 35. The two ends of the two arc-shaped lower protruding edges 34 are opposite to each other, and a buckle 32 is provided between the ends of the two lower protruding edges 34.
[0058] The fastening structure between the inner cover 7 and the outer cover 1 can be disengaged by external force causing the buckle body 32 to undergo elastic deformation, thereby disengaging the snap-fit protrusion 31 from the buckle body 32.
[0059] Preferably, the water inlet 11 is provided on the side wall of the sleeve 13, and the side wall of the sleeve 13 is provided with two water inlets 11. The sleeve body 24 is provided with the same number of openings 26 as the water inlets 11, and the drinking spout 17 is provided with the same number of limiting protrusions 28 and locking parts 27 as the openings 26.
[0060] The upper body 2 is inserted into the top opening 5 to fill the top opening 5, so that the outside of the cup lid looks flatter and more beautiful.
[0061] The top of the pressure plate 14 is provided with a raised positioning protrusion 16 inside the upper ring edge 30, and the lower seat body 19 is provided with a positioning hole 15 corresponding to the positioning protrusion 16. The positioning protrusion 16 is inserted into the positioning hole 15, so that the upper part of the soft connector is more stably connected to the cover.
[0062] The bottom of the sleeve 24 is provided with a connecting part 22, and the bottom of the sleeve 13 is provided with a connecting hole 21. The connecting part 22 passes through the connecting hole 21. The lower end of the connecting part 22 is provided with a stop 23 that is limited below the lower edge of the opening of the connecting hole 21. The connecting part 22 is connected to the bottom of the sleeve 13, so that the lower part of the soft connector is more stably connected to the cover. The stop 23 can be deformed by external force so that it can pass through the connecting hole 21 to achieve disassembly.
[0063] Figure 3 As shown, the pressure plate 14 has an air inlet 20 located inside the upper ring edge 30, and the top of the upper seat 2 has a vent 6 that connects to the external atmosphere and the air inlet 20. A one-way valve 12 is provided at the air inlet 20 to restrict air from entering the inner side of the lid only from the outside through the air inlet 20. When the container is inverted for direct drinking, the liquid inside the container can flow out from the drinking spout 17, and external air can enter through the vent 6, pass through the air inlet 20, and then enter the container to balance the pressure inside the container.
[0064] Preferably, the one-way valve 12 can be an elastic valve plate installed on the pressure plate 14. In its natural state, the elastic valve plate covers the air inlet 20 to seal the air inlet 20. When the pressure inside the cover is less than the pressure of the external atmospheric environment, the external air squeezes the elastic valve plate, causing the elastic valve plate to deform elastically, thereby forming a gap between the elastic valve plate and the pressure plate 14, allowing air to enter the inside of the cover from the air inlet 20 through the gap to balance the pressure inside the container.
[0065] Figure 11 , Figure 12 As shown, the bottom of the lower body 19 is provided with an opening groove 18 facing downwards. The opening groove 18 is connected to the vent hole 6 and is located above the air inlet hole 20. The air inlet hole 20 is surrounded by multiple supporting protrusions 37. The supporting protrusions 37 are inserted into the opening groove 18 and abut against the inner side wall of the opening groove 18 to support the opening groove 18 and prevent the opening groove 18 from deforming and affecting the stability of ventilation. External air can enter the opening groove 18 through the vent hole 6 and then enter the inner side of the cover body through the air inlet hole 20.
[0066] The inner wall of the outer cover 1 is provided with an internal thread for connecting with the cup body. The bottom of the pressure plate 14 is provided with a downward protruding lower ring edge 8. An annular groove 10 is formed between the lower ring edge 8 and the inner wall of the outer cover 1. A sealing rubber ring 9 is inserted into the annular groove 10. When the upper end of the cup body is inserted into the internal thread of the outer cover 1 for connection, the edge of the cup mouth at the upper end of the cup body abuts against the sealing rubber ring 9 to seal the gap between the cup mouth and the inner wall of the outer cover 1.
[0067] A flexible silicone spout 3 is fitted around the opening edge of the upper end of the drinking spout 17 to improve the comfort of contact between the drinking spout 17 and the mouth. The soft connector is made of soft silicone. The silicone spout 3 and the soft connector can be made of food-grade, high-temperature resistant silicone.
[0068] The above describes the lifting spout cup lid provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
