Description

Anti-scalding cup lid with temperature adjustment function

This invention relates to a heat-adjustable cup lid, and more particularly to a heat-adjustable cup lid that can adjust the temperature of a beverage to a suitable drinking temperature via a temperature regulator, thereby preventing the drinker from being burned by a hot beverage.

Among various beverages, many require hot water to extract their flavor, such as coffee and tea. Others are consumed hot according to personal preference. Regardless, hot drinks are the preferred method of consumption. However, these hot drinks can easily cause heat-related injuries during consumption, such as burns to the hands and mouth, affecting the drinking experience. While insulation or handles can prevent hand burns in the container, the beverage itself remains at the high temperature of brewing, which can still cause mouth injuries when consumed.

Generally, the main methods for cooling beverages are natural heat dissipation or the addition of cooling agents. Firstly, natural heat dissipation means that hot beverages will continue to cool down from room temperature until they reach a temperature similar to the surrounding environment—a temperature that is not too hot to drink, allowing the user to enjoy it with peace of mind. However, this takes a significant amount of time, greatly diminishing the drinking experience for users who want to drink immediately. For rapid cooling, ice cubes or other cooling agents can be added to quickly reach a suitable drinking temperature. However, these cooling agents are not readily available and are often difficult to obtain when not easily portable.

In summary, although there are existing methods for cooling hot beverages, these methods are limited by waiting time or the required cooling medium, making it difficult to achieve a simple and rapid cooling effect. Therefore, the inventors of this invention have conceived and designed a scald-resistant cup lid with temperature adjustment function to improve upon the problems of prior art and thereby enhance its industrial application.

In view of the problems of the above-mentioned prior art, the purpose of this invention is to provide a scald-proof cup lid with temperature adjustment function to solve the problem that high-temperature beverages are difficult to cool to a suitable drinking temperature through simple holding devices.

According to one objective of this invention, a heat-resistant cup lid with temperature adjustment function is proposed, which includes a lid body, a temperature regulator, and an adjustment dial. The lid body is disposed on a beverage container and includes a bottom surface, a lid shell, and a top surface. The bottom surface of the lid has a beverage inlet, and the top surface has a beverage outlet. The beverage inlet and beverage outlet are connected to a receiving space within the lid shell. The temperature regulator is located within the container. It features a spiral tube, one end of which connects to the beverage inlet. The spiral tube has multiple cooling nodes and corresponding pipe openings, each connecting to a beverage outlet. An adjustment dial is located on the top of the lid. This dial has multiple gates, each corresponding to a pipe opening. The adjustment dial controls the opening and closing of these gates to adjust the spiral tube's connection to the beverage outlet from one of the cooling nodes.

Preferably, the beverage inlet can be located at the edge or center of the bottom surface of the lid, and the beverage outlet can be located at the edge of the top surface of the lid.

Preferably, multiple pipe openings can be located at the top or side of the pipe wall of the spiral pipe.

Preferably, the plurality of gates may each have a control element and a blocking element. The control element is connected to an adjustment dial, and the blocking element is connected to the control element and blocks the plurality of pipe openings. When the adjustment dial is turned to one of the plurality of gates, the corresponding control element moves the blocking element to expose one of the plurality of pipe openings.

Preferably, the temperature regulator can be configured with a plurality of cooling chips, each located at a plurality of cooling nodes.

Preferably, the adjustment dial can be set with multiple switches, which are connected to multiple cooling chips. The adjustment dial controls the opening and closing of the multiple switches, driving the multiple cooling chips to cool the multiple nodes.

Preferably, the spiral duct can be equipped with 3 cooling nodes.

Preferably, the temperature drop between multiple cooling nodes is approximately 5°C to 10°C.

Preferably, the spiral duct can be equipped with 5 cooling nodes.

Preferably, the temperature drop between multiple cooling nodes is approximately 3°C to 8°C.

As described above, the scald-proof cup lid with temperature adjustment function according to the present invention may have one or more of the following advantages:

(1) This heat-adjustable anti-scalding cup lid has a spiral channel for temperature adjustment, which allows the beverage to be cooled as it flows through the channel. When the beverage flows out of the cup lid, it is at a suitable drinking temperature, which enhances the drinking experience and avoids the risk of burns caused by high temperature.

(2) This heat-adjustable, scald-proof cup lid can adjust the degree of beverage cooling by adjusting the dial. That is, the length of the beverage flowing through the spiral tube is defined by the flow of the beverage at different cooling nodes, thereby achieving the effect of controlling the cooling range. This allows users to select different cooling ranges through simple operation, increasing the applicability to different temperatures or beverage types.

(3) This heat-adjustable anti-scalding cup lid can lower the temperature of the beverage through the structure inside the lid. It is suitable for various beverage containers and does not require carrying coolant or other additional media, increasing the convenience of use and improving the user's drinking experience by providing the best drinking temperature.

To facilitate understanding of the technical features, content, advantages, and effects of this invention, the invention is described in detail below with accompanying drawings and in the form of embodiments. The drawings used are for illustrative and explanatory purposes only and may not represent the actual scale and precise configuration of the invention in practice. Therefore, the scale and configuration of the accompanying drawings should not be interpreted or used to limit the scope of the invention in actual practice. This is stated above.

Please refer to Figure 1, which is a schematic diagram of a scald-proof cup lid with temperature adjustment function according to an embodiment of the present invention. As shown in the figure, the scald-proof cup lid 10 with temperature adjustment function includes a lid body 11, a temperature regulator 21, and an adjustment dial 31. The lid body 11 is cylindrical in shape and is disposed on the beverage container 90, serving as a lid to cover the mouth of the beverage container 90 to prevent beverage spillage. The lid body 11 includes a bottom surface 12, a lid shell 13, and a top surface 14, which can be made of plastic or metal. The bottom surface 12 contacts the rim of the beverage container 90. A beverage inlet 15 is provided at the edge of the bottom surface 12. When the user tilts the beverage container 90, the beverage flows from the beverage inlet 15 into the receiving space 16 inside the lid shell 13. A beverage outlet 17 is provided at the edge of the top surface 14. The beverage inlet 15 and the beverage outlet 17 are connected to the receiving space 16 inside the lid shell 13. The beverage flows out through the beverage outlet 17 to provide drinking for the user.

Users often prefer hot beverages such as coffee, tea, and soy milk. However, these drinks are frequently too hot to drink smoothly, especially when drinking through the lid. Because the lid obscures the drink's temperature, users may not be able to perceive it, potentially causing burns when the beverage flows from the spout 17. To address this issue, this invention discloses a temperature regulator 21 within the lid body 11 to appropriately cool the beverage, ensuring it flows out at the optimal drinking temperature.

Temperature regulator 21 is disposed in housing space 16. Temperature regulator 21 is provided with spiral pipe 22. Please also refer to Figure 2, which is a schematic diagram of temperature regulator of embodiment of the present invention. As shown in the figure, one end of spiral pipe 22 is connected to beverage inlet 15. Spiral pipe 22 is provided with a plurality of cooling nodes and a plurality of pipe openings corresponding to the plurality of cooling nodes. In this embodiment, spiral pipe 22 is provided with 5 cooling nodes, namely first cooling node 23A, second cooling node 23B, third cooling node 23C, fourth cooling node 23D and fifth cooling node 23E, corresponding to first pipe opening 24A, second pipe opening 24B, third pipe opening 24C, fourth pipe opening 24D and fifth pipe opening 24E. In this embodiment, the pipe opening is located at the top of the pipe wall of the cooling node, but this disclosure is not limited to this. In other embodiments, the pipe opening may also be located on the side of the pipe wall of the cooling node.

After the beverage flows in through the beverage inlet 15, it flows along the spiral pipe 22, which can be made of a heat-dissipating metal material. After traveling a predetermined flow distance, the beverage is appropriately cooled. For example, between the five cooling nodes, the temperature drop between each node is approximately 3°C to 8°C, and the beverage temperature can be reduced by approximately 15°C to 40°C through the five nodes. Therefore, when the hot beverage flows out through the beverage outlet 17, the temperature can be reduced to a suitable drinking temperature, preventing the drinker from being burned and improving the satisfaction of the drinking process.

Since the spiral pipe 22 is provided with a plurality of heat dissipation nodes, the cooling range can be adjusted by flowing through different numbers of nodes. To control the temperature adjustment, an adjustment dial 31 is provided on the top surface 14 of the lid. Please also refer to Figure 3, which is a schematic diagram of the adjustment dial of this embodiment. As shown in the figure, the adjustment dial 31 is a circular dial slightly smaller than the top surface 14 of the lid, and its perimeter can be provided with a serrated shape to facilitate the user to rotate this adjustment dial 31 to the set position. The adjustment dial 31 has a plurality of gates, which correspond to a plurality of pipe openings. The adjustment dial 31 controls the opening or closing of the plurality of gates. In this embodiment, five gates are provided corresponding to the five cooling nodes. Each gate has a control element 32 and a blocking element 33. The control element 32 is connected to an adjustment dial 31, and the blocking element 33 is connected to the control element 32 and blocks a plurality of pipe openings. When the adjustment dial 31 is rotated to one of the positions of the plurality of gates, the corresponding control element 32 moves the blocking element 33 to expose one of the plurality of pipe openings. For example, when the adjustment dial 31 is rotated to scale A, the control element 32 moves the blocking element 33 on the first cooling node 23A, exposing the first pipe opening 24A. The beverage enters the receiving space 16 through the first pipe opening 24A and then flows out from the beverage outlet 17 to provide a drink for the user. If the scale is turned to B, the control unit 32 removes the block 33 on the second cooling node 23B, exposing the second pipe opening 24B. The beverage flows through the first cooling node 23A and the second cooling node 23B, then enters the receiving space 16 through the second pipe opening 24B, and finally flows out from the beverage outlet 17 to be consumed by the user. Similarly, by controlling the length of the beverage flowing through the spiral pipe 22, the range of cooling temperature is adjusted to achieve the optimal drinking temperature.

Please refer to Figure 4, which is a schematic diagram of a scald-proof cup lid with temperature adjustment function according to another embodiment of the present invention. As shown in the figure, the scald-proof cup lid 40 with temperature adjustment function includes a lid body 41, a temperature regulator 51, and an adjustment dial 61. The lid body 41 is cylindrical in shape and is disposed on the beverage container 91, serving as a lid to cover the mouth of the beverage container 91 to prevent beverage from spilling. The lid body 41 includes a bottom surface 42, a lid shell 43, and a top surface 44, which can be made of plastic or metal. The bottom surface 42 contacts the rim of the beverage container 91. A beverage inlet 45 is provided in the center of the bottom surface 42. When the user tilts the beverage container 91, the beverage flows from the beverage inlet 45 into the receiving space 46 inside the lid shell 43. A beverage outlet 47 is provided at the edge of the top surface 44. The beverage inlet 45 and the beverage outlet 47 are connected to the receiving space 46 inside the lid shell 43. The beverage flows out through the beverage outlet 47 to provide drinking for the user.

Similar to the aforementioned embodiments, hot beverages can easily cause burns. Therefore, a temperature regulator 51 is provided inside the lid body 41 to appropriately cool the beverage, ensuring that the beverage is at the optimal drinking temperature when it flows out. Please also refer to Figure 5, which is a schematic diagram of a temperature regulator according to another embodiment of the present invention. As shown in the figure, the temperature regulator 51 is provided with a spiral pipe 52, one end of which is connected to a beverage inlet 45. The spiral pipe 52 is provided with a plurality of cooling nodes and a plurality of pipe openings corresponding to the plurality of cooling nodes. In this embodiment, the spiral pipe 52 is provided with three cooling nodes, namely a first cooling node 53A, a second cooling node 53B, and a third cooling node 53C, corresponding to a first pipe opening 54A, a second pipe opening 54B, and a third pipe opening 54C. In this embodiment, the pipe openings are located at the top of the pipe wall of the cooling nodes, but this disclosure is not limited to this. In other embodiments, the pipe openings may also be located on the side of the pipe wall of the cooling nodes.

After the beverage flows in through the beverage inlet 45, it flows along the spiral pipe 52, which can be made of a heat-dissipating metal material. After traveling a predetermined flow distance, the beverage is appropriately cooled. For example, between the three cooling nodes, the temperature drop between each node is approximately 5°C to 10°C, and the beverage temperature can be reduced by approximately 15°C to 30°C through the three nodes. Therefore, when the hot beverage flows out through the beverage outlet 47, the temperature can be reduced to a suitable drinking temperature, preventing the drinker from being burned and improving the satisfaction of the drinking process.

Since the spiral pipe 52 is provided with a plurality of heat dissipation nodes, the cooling range can be adjusted by flowing through different numbers of nodes. To control the temperature adjustment, an adjustment dial 61 is provided on the top surface 44 of the lid. Please also refer to Figure 6, which is a schematic diagram of an adjustment dial of another embodiment of the present invention. As shown in the figure, the adjustment dial 61 is a circular dial slightly smaller than the top surface 44 of the lid, and its periphery can be provided with a serrated shape to facilitate the user to rotate this adjustment dial 61 to the set position. The adjustment dial 61 has a plurality of gates, which correspond to a plurality of pipe openings. The adjustment dial 61 controls the opening or closing of the plurality of gates. In this embodiment, three gates are provided corresponding to the three cooling nodes. Each gate has a control element 62 and a blocking element 63. The control element 62 is connected to an adjustment dial 61, and the blocking element 63 is connected to the control element 62 and blocks a plurality of pipe openings. When the adjustment dial 61 is rotated to one of the positions of the plurality of gates, the corresponding control element 62 moves the blocking element 63 to expose one of the plurality of pipe openings. For example, when the adjustment dial 61 is rotated to scale A, the control element 62 moves the blocking element 63 on the first cooling node 53A, exposing the first pipe opening 54A. The beverage enters the receiving space 46 through the first pipe opening 54A and then flows out from the beverage outlet 47 to provide a drink for the user. If the scale is turned to B, the control unit 62 removes the block 63 on the second cooling node 53B, exposing the second pipe opening 54B. The beverage flows through the first cooling node 53A and the second cooling node 53B, then enters the receiving space 46 through the second pipe opening 54B, and finally flows out from the beverage outlet 47 to be consumed by the user. Similarly, by controlling the length of the beverage flowing through the spiral pipe 52, the range of cooling temperature is adjusted to achieve the optimal drinking temperature.

In this embodiment, the temperature regulator 51 may further be provided with a plurality of cooling chips 55, which are respectively disposed at the positions of a plurality of cooling nodes, for example, the cooling chips 55 are disposed on the side of the first cooling node 53A, the second cooling node 53B and the third cooling node 53C. And a switch is provided corresponding to each cooling chip 55, and the switch is connected to the adjustment dial 61. When the adjustment dial 61 is rotated to the scale of the corresponding node, the adjustment dial 61 drives the switch to turn on the corresponding cooling chip 55, thereby driving the plurality of cooling chips 55 to cool the plurality of nodes. For example, when the adjustment dial 61 is rotated to scale C, in addition to the control unit 62 removing the block 63 on the third cooling node 53C to expose the third pipe opening 54C, the cooling chips 55 of the three nodes are activated at the same time, so that when the beverage passes through the first cooling node 53A, the second cooling node 53B and the third cooling node 53C, it can be further cooled to reach the expected drinking temperature.

In this disclosure, three nodes and five nodes are used as examples to illustrate different temperature adjustment zones. However, the number and position of nodes are not limited to the embodiments. In other embodiments, the number and position of nodes in the spiral pipe can be adjusted according to the size of the cup lid, the cooling range, and other requirements.

The above description is illustrative and not restrictive. Any equivalent modifications or alterations made to this invention without departing from its spirit and scope shall be included in the scope of the appended patent application.
