Description

Technical Field

[0001] This utility model belongs to the field of cold drink cup technology, specifically a cold drink cup based on a water bath cooling method. Background Technology

[0002] The Chinese market for new-style tea drinks has exceeded 100 billion yuan, with iced drinks accounting for over 70% in summer. Currently, mainstream products (such as milk tea, fruit tea, and coffee) rely on ice for cooling, with an average of 80-150g of ice added per cup. However, melting ice dilutes the drink, reducing sweetness and flavor concentration, especially affecting dairy-based products. When ice directly contacts the drink, the water content after melting can reach 20%-30% of the total volume, significantly reducing sweetness and flavor concentration in dairy products, impacting taste stability. Changing the amount of ice only alters the time it takes to heat the drink; the drink remains at 0℃, but the temperature cannot be fundamentally adjusted (not all drinks taste best at 0℃).

[0003] Existing solutions focus on reducing the amount of ice added (such as "less ice" or "no ice" options), but they cannot maintain the taste of the drink or control the temperature of the drink.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a cold drink cup based on a water bath cooling method. Utility Model Content

[0005] To address the aforementioned technical problems, this invention provides a cold drink cup based on a water bath cooling method, which solves the problems in the prior art where melting ice cubes dilute the drink, leading to a decrease in the concentration of flavor substances and the inability to adjust the drink temperature.

[0006] A cold drink cup based on a water bath cooling method, comprising:

[0007] The outer cup has several supporting ribs arranged in a circumferential array on its inner bottom wall.

[0008] The inner cup has several limiting ribs arranged in a circular array on its outer wall. The inner cup is placed on the upper surface of the supporting ribs. The bottom surface of the inner cup and the inner surface of the outer cup form an ice storage groove. The limiting ribs are in contact with the inner wall of the outer cup.

[0009] A cup lid that engages with both the outer and inner cups.

[0010] Preferably, the bottom surface of the cup lid is provided with a first groove and a second groove, the first groove engaging with the outer edge of the inner cup, and the second groove engaging with the outer edge of the outer cup.

[0011] Preferably, the bottom surface of the limiting rib is provided with a guide portion.

[0012] Preferably, a hollow layer is provided around the outer cup.

[0013] Preferably, the upper surface of the cup lid is provided with a drinking hole, a straw hole and a vent hole, the drinking hole is fitted with a first sealing cap and the straw hole is fitted with a second sealing cap.

[0014] Preferably, the upper surface of the cup lid is provided with a positioning groove, the vent hole is provided on the inner surface of the positioning groove, the first sealing cover is an elliptical structure, the second sealing cover is a circular structure, the major axis of the first sealing cover is the same as the diameter of the second sealing cover, and both the first sealing cover and the second sealing cover are engaged with the positioning groove.

[0015] Preferably, the outer cup and the inner cup have the same inclination angle, and the outer cup is thicker than the inner cup.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention features an outer cup, an inner cup, and a lid. The ice-water mixture exchanges heat with the beverage through the inner cup wall, achieving stable cold or hot beverage operation without altering the beverage concentration. Users can increase the amount of ice-water mixture filling the outer cup to change the contact area between the ice-water and the inner cup. The more ice-water mixture there is, the larger the heat exchange area, and the lower the beverage temperature. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 5 As shown: This utility model provides a cold drink cup based on a water bath cooling method, including an outer cup 1, an inner cup 4, and a lid 6. The walls of the outer cup 1 and the inner cup 4 have the same tilt angle. The outer cup 1 is thicker than the inner cup 4. The thinner wall of the inner cup 4 can accelerate the heat exchange between the ice water and the beverage, achieving rapid cooling. The temperature is adjusted when the beverage is put into the cup, and the ice water plays a role in maintaining the temperature. The thicker wall of the outer cup 1 blocks the conduction of external heat, preventing the ice water mixture from heating up too quickly and preventing the outside air from forming condensation on the outer wall of the outer cup, which would make the cup wall covered with droplets and affect the user's use.

[0027] As attached Figure 3 and attached Figure 5 As shown: The inner bottom wall of the outer cup 1 is equipped with a plurality of supporting ribs 2 arranged in a circumferential array; the outer wall of the inner cup 4 is equipped with a plurality of limiting ribs 5 arranged in a circumferential array. The inner cup 4 is placed on the upper surface of the supporting ribs 2. The bottom surface of the inner cup 4 and the inner surface of the outer cup 1 form an ice storage groove 201. The limiting ribs 5 are in contact with the inner wall of the outer cup 1, and the bottom surface of the limiting ribs 5 is provided with a guide part 501. The supporting ribs 2 can support the inner cup 4, and the limiting ribs 5 can limit the position of the inner cup 4, effectively preventing the inner cup 4 from shaking. The outer cup 1 and the inner cup 4 have inclined walls at the same angle, which allows them to fit stably when nested. The limiting rib 5 fits more tightly with the inner wall of the outer cup 1. The guide part 501 slides along the inclined wall surface to achieve quick and accurate positioning of the inner cup 4, avoiding jamming or shaking caused by angle differences. The uniform inclination angle can reduce the complexity of the mold, reduce the manufacturing difficulty of the inner cup 4 and the outer cup 1, and improve production efficiency. The inclined wall surface at the same angle makes the ice-water mixture more evenly distributed in the ice storage tank 201.

[0028] Ice can be quickly placed in the ice storage tank 201, and then water is added to form an ice-water mixture in the outer cup 1. The inner cup 4 is then inserted into the outer cup 1, and the beverage is cooled by the wall of the inner cup 4. By adjusting the amount of water in the outer cup 1, the contact area between the ice and water and the wall of the inner cup 4 is changed, thereby adjusting the temperature of the beverage. The more water, the larger the heat exchange area, and the colder the beverage.

[0029] As attached Figure 4 and attached Figure 5 As shown: Cup lid 6, which engages with outer cup 1 and inner cup 4. The bottom surface of cup lid 6 is provided with a first groove 601 and a second groove 602. The first groove 601 engages with the outer edge of inner cup 4, and the second groove 602 engages with the outer edge of outer cup 1. Cup lid 6 can seal outer cup 1 and inner cup 4 at the same time.

[0030] A hollow layer 3 is provided around the outer cup 1. The hollow layer 3 isolates external heat conduction, prolongs the cooling time of the ice-water mixture, and prevents condensation from forming on the outer wall of the outer cup, which would cause the cup wall to be covered with droplets and affect the user's use. The inner cup 4 is suspended above the ice storage tank 201 by the supporting ribs 2, which makes it easy to place ice cubes in the ice storage tank 201. At the same time, the limiting ribs 5 and the guide part 501 ensure that the inner cup is stable and does not shake. The ice-water mixture exchanges heat with the beverage through the inner cup wall. The user can adjust the contact area between the ice water and the inner cup 4 by adjusting the water volume in the outer cup, so as to flexibly control the temperature of the beverage, taking into account both rapid cooling and long-term heat preservation needs, without diluting the beverage.

[0031] Add ice to the ice storage tank 201 up to the upper surface of the support rib 2. Add water to different scale lines according to the temperature requirements of the beverage. The scale lines are located on the outer cup wall and are scale line 1, scale line 2, and scale line 3 from bottom to top.

[0032] For beverages at 0-3℃, add water to the 3 mark; the ice water will then contact the entire outer wall of the inner cup.

[0033] For drinks at 4-7℃, add water to the 2 mark; the ice water will then be in contact with two-thirds of the inner cup's outer wall.

[0034] For drinks at 8-11℃, add water to the 1 mark; the ice water will then be in contact with one-third of the inner cup's outer wall.

[0035] Then, pour the pre-temperatured beverage into the inner cup 4, and finally place the inner cup 4 into the outer cup 1 and cover it with the lid 6.

[0036] As shown above, during use, ice cubes are first poured into the ice storage tank 201 at the bottom of the outer cup 1, followed by the addition of an appropriate amount of cold water to form an ice-water mixture. The inner cup 4 is suspended inside the outer cup 1 by the supporting ribs 2 at its bottom, and the limiting ribs 5 on its outer wall fit snugly against the inner wall of the outer cup, working in conjunction with the guide part 501 to achieve precise positioning and ensure the stability of the inner cup without shaking. When cold drinks are poured into the inner cup 4, the ice water exchanges heat with the drink through the inner cup wall, achieving the effect of maintaining the drink's low temperature. The hollow layer 3 of the outer cup 1 can reduce external heat conduction and prolong the cooling time; by increasing or decreasing the amount of water in the outer cup, the contact area between the ice water and the inner cup 4 can be adjusted, effectively keeping different types of drinks cold.

[0037] Example 2: Based on Example 1, the upper surface of the cup lid 6 is provided with a drinking hole 603, a straw hole 604, and a vent hole 607. The drinking hole 603 is engaged with a first sealing cap 608, and the straw hole 604 is engaged with a second sealing cap 605. The upper surface of the cup lid 6 is provided with a positioning groove 606, and the vent hole 607 is opened on the inner surface of the positioning groove 606. The first sealing cap 608 has an elliptical structure, and the second sealing cap 605 has a circular structure. The major axis of the first sealing cap 608 and the diameter of the second sealing cap 605 are the same. Both the first sealing cap 608 and the second sealing cap 605 are engaged with the positioning groove 606.

[0038] As shown above, the first groove 601 engages with the outer edge of the inner cup 4, and the second groove 602 fits with the outer edge of the outer cup 1, forming a double seal to prevent leakage. The drinking hole 603 and the straw hole 604 can be switched according to needs. Depending on the chosen drinking method, the first sealing cap 608 or the second sealing cap 605 can be removed and fixed by the positioning groove 606 to maintain hygiene. The vent 607 is used to balance the internal and external air pressure and prevent liquid splashing when the lid is opened. This design not only ensures the cooling efficiency of the beverage, but also allows for functional expansion through a modular structure to meet the needs of different scenarios.

[0039] The double-groove sealing design 601 and 602 of the cup lid 6 simultaneously locks the inner and outer cups, effectively preventing leakage. The direct drinking hole 603 and straw hole 604 support multiple drinking scenarios. The first sealing cap 608 and the second sealing cap 605 are fixed by the positioning groove 606 to ensure hygiene. The vent 607 balances air pressure and prevents liquid splashing when the lid is opened. The modular design of the overall structure facilitates disassembly and cleaning, the inclined cup wall reduces beverage residue, and the easy-to-stuff design facilitates transportation and storage, improving practicality. Through structural optimization, this product significantly outperforms traditional cold drink containers in maintaining beverage flavor and temperature, cooling efficiency, ease of use, sealing, and hygiene, meeting the tea beverage industry's precise pursuit of beverage quality and the diverse needs of outdoor portability and home refrigeration.

[0040] This cold drink cup technology is suitable for tea shops, coffee shops, convenience stores and other scenarios, helping merchants improve product competitiveness, accurately control the taste of drinks, and support long-term heat preservation and portability.
