Description

Technical Field

[0001] This utility model relates to an integrated, temperature-resistant, and non-deformable food preservation cup. Background Technology

[0002] As people increasingly pursue a higher quality of life, portable insulated water bottles have become a common product in daily life and are gradually being widely used. The core function of an insulated water bottle is to maintain the temperature of beverages, especially when out and about, effectively delaying temperature changes and providing a better user experience. However, in current technology, most insulated water bottles still have some technical shortcomings while maintaining temperature, particularly in terms of heat insulation performance, temperature resistance, and deformation control.

[0003] Most existing thermos flasks employ a double-walled design, with a vacuum layer between the inner liner and the outer shell for insulation, or use foam material as the inner liner. However, while traditional vacuum layer designs can insulate against heat conduction to some extent, their effectiveness in mitigating temperature changes is limited. Furthermore, the insulation materials in existing thermos flasks are often relatively simple foam or plastic materials, whose insulation performance is affected by temperature changes, making them prone to deformation or uneven heat conduction.

[0004] Furthermore, many insulated cups perform poorly in terms of high-temperature resistance and deformation resistance. When exposed to high or low temperatures, the outer shell and inner liner materials may expand, contract, or deform, leading to damage to the appearance of the cup and even affecting its overall function and lifespan. Therefore, improving the temperature resistance and deformation resistance of insulated cups has always been a pressing issue in insulation technology. Utility Model Content

[0005] The purpose of this invention is to provide an integrated, temperature-resistant, and non-deformable food preservation cup. By optimizing the structure of the inner liner and vacuum layer, selecting a high-efficiency heat insulation layer, and designing a reasonable bubble liner, the shortcomings of the existing technology are solved, thereby improving the performance of the thermos cup in high or low temperature environments, preventing deformation, and extending its service life.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A one-piece, temperature-resistant, and non-deformable food preservation cup includes a cup body, an inner liner integrally formed with the cup body, and a liquid container disposed within the inner liner. The cup body has a vacuum layer, and the inner liner is disposed between the vacuum layer and the liquid container. The inner liner is filled with water and a layer of SAP polymer resin, and has one or more bubble-shaped elastic soft rubbers inside. The inner liner has one or more annular grooves that separate the individual bubble-shaped elastic soft rubbers.

[0008] Preferably, the bubble-shaped elastic soft rubber is hollow inside and filled with gas, and the bubble-shaped elastic soft rubber comes into contact with the coolant.

[0009] Preferably, the bubble-shaped elastic soft rubber is evenly distributed within the inner liner body, and each bubble-shaped elastic soft rubber has a corresponding annular groove.

[0010] Preferably, the inner liner is provided with an injection hole on the inner side and a plug for blocking the injection hole. The plug is an elastic soft rubber with a hollow cavity and is filled with a steel ball that allows the silicone to expand outward.

[0011] Preferably, the bubble-shaped elastic soft rubber is in the form of tubular bubbles, block bubbles, or capsule-shaped bubbles.

[0012] Preferably, the bubble-shaped elastic soft rubber is in the shape of a round tube, and the round tube-shaped bubble-shaped elastic soft rubber is curved and connected at both ends to form a ring tube.

[0013] Preferably, the diameter of the tubular bubble-shaped elastic soft rubber is less than or equal to the distance between the two walls of the inner cavity of the inner liner.

[0014] Preferably, the cup body is provided with a cup lid, and the liquid container is one or more baby bottles arranged in a stacked manner.

[0015] The beneficial effects of this utility model are:

[0016] By filling the inner liner with water and a layer of SAP polymer resin, combined with a design of bubble-shaped elastic soft rubber and annular grooves, the thermal insulation performance of the thermos is effectively improved. The bubble-shaped elastic soft rubber helps to form an insulating bubble layer, thereby reducing heat conduction, while the SAP polymer resin layer further enhances the thermal insulation effect, ensuring that heat is retained inside the container for a long time and improving the heat preservation effect.

[0017] The inner liner uses bubble-shaped elastic soft rubber and annular grooves to effectively control internal temperature fluctuations, preventing the material from expanding and contracting due to excessive temperature changes. This design effectively prevents the thermos from deforming in high or low temperature environments, improving its temperature resistance and ensuring it remains stable even after long-term use.

[0018] The vacuum layer, combined with the inner liner between the liquid container and the vacuum layer, enhances the insulation effect through a design using bubble-shaped elastic soft rubber and annular grooves. This design prevents heat conduction, and the combination of multiple inner liner layers allows the thermos to maintain temperature more efficiently during use, while reducing the impact of internal and external temperature differences on the structure, ensuring that the insulation effect is not affected by external temperature changes.

[0026] See Figure 1-4 As shown, an integrated, temperature-resistant, and non-deformable food preservation cup includes a cup body 1, an inner liner 2 integrally formed with the cup body 1, and a liquid container 3 disposed within the inner liner 2. The cup body 1 has a vacuum layer 11, and the inner liner 2 is disposed between the vacuum layer 11 and the liquid container 3. The inner liner 2 is filled with water and a SAP polymer resin layer 21, and has one or more bubble-shaped elastic soft rubbers 22 disposed inside. The inner liner 2 has one or more annular grooves 23 formed on it, which can separate the individual bubble-shaped elastic soft rubbers 22.

[0027] The inner liner 2 is filled with water and a SAP polymer resin layer 21. This material has excellent thermal insulation properties, which can significantly reduce heat transfer and thus effectively maintain the temperature inside the liquid container 3. The SAP polymer resin layer not only has high thermal insulation performance, but also further enhances the heat preservation effect when liquid water and resin are combined, maintaining the temperature for a long time.

[0028] The bubble-shaped elastic soft rubber 22 installed inside the inner liner 2 can maintain a stable heat insulation effect in environments with large temperature fluctuations. The structure of the bubble-shaped elastic soft rubber helps to form a bubble layer, slowing down heat conduction, thereby protecting the inner liner 2 from expansion or contraction due to changes in high or low temperatures. The design of the annular groove 23 further prevents the bubble-shaped elastic soft rubber 22 from moving, maintaining the durability of its heat insulation function and preventing deformation under conditions of large external temperature changes.

[0029] The inner liner 2 between the vacuum layer 11 and the liquid container 3 employs multiple insulation measures to enhance overall structural stability. The annular groove 23 effectively separates the bubble-shaped elastic soft rubber 22, reducing mutual interference between bubbles and ensuring each bubble performs at its maximum insulation efficiency. This not only improves heat preservation performance but also enhances the durability of the thermos, preventing structural damage caused by external forces or high-temperature environments during long-term use.

[0030] The use of environmentally friendly materials such as SAP polymer resin and bubble-shaped elastic soft rubber 22 can improve the product's environmental friendliness to a certain extent. These materials have a long service life, can withstand long-term heat changes without aging, thus extending the life of the thermos cup and reducing the need for frequent product replacement.

[0031] The materials and structure of this design provide excellent heat retention without adding extra weight. The lightweight nature of the bubble-shaped flexible soft rubber 22 effectively reduces the overall weight of the thermos, improving ease of use and making it especially suitable for everyday carrying.

[0032] The bubble-shaped elastic soft rubber 22 is hollow inside and filled with gas, and the bubble-shaped elastic soft rubber 22 comes into contact with the coolant; the bubble-shaped elastic soft rubber 22 is evenly distributed inside the inner liner 2, and each bubble-shaped elastic soft rubber 22 is provided with a corresponding annular groove 23; the inner liner 2 is provided with a liquid injection hole 24 on the inner side, and a plug 25 for blocking the liquid injection hole 24. The plug 25 is an elastic soft rubber with a hollow cavity, and a steel ball 26 is inserted inside to allow the silicone to expand outward.

[0033] The bubble-shaped elastic soft rubber 22 is hollow and filled with gas, forming a cavity structure with excellent heat insulation properties. The bubble-shaped elastic soft rubber 22 effectively slows down heat conduction, further enhancing the heat preservation effect. Because these elastic soft rubbers are in contact with the coolant, the coolant helps absorb and disperse the incoming heat, making it difficult for heat to be directly transferred to the inner liner 2, thereby improving the overall heat insulation performance and maintaining the temperature of the liquid inside the cup.

[0034] The bubble-shaped elastic soft rubber 22 is evenly distributed within the inner liner 2, with each bubble-shaped elastic soft rubber 22 corresponding to an annular groove 23. This structure ensures that each bubble-shaped elastic soft rubber can perform its heat insulation function, while the annular groove 23 maintains the stable position of the elastic soft rubber, preventing it from moving or shifting, and ensuring that the effect of the inner liner 2 is not affected by external factors. In addition, the evenly distributed bubble-shaped elastic soft rubber makes the heat insulation effect of the entire thermos cup more uniform, thereby enhancing the overall heat preservation performance.

[0035] The inner liner 2 has an inlet 24 facing inwards, which is plugged with a stopper 25. This design facilitates the injection of coolant during production and ensures uniform liquid distribution. The inlet 24 effectively guides the coolant into the cavity of the bubble-shaped elastic soft rubber 22, thereby improving its cooling effect and enhancing the stability of the elastic soft rubber. When needed, the stopper 25 of the inlet 24 also facilitates maintenance or replacement of the coolant, ensuring the long-term stable performance of the thermos.

[0036] A plug 25 with a hollow cavity is made of elastic soft rubber, and then a steel ball 26 is inserted into the hollow cavity, causing the elastic soft rubber to expand outward. This non-removable plug provides a one-time seal. Compared to previous processes, this technology not only significantly reduces costs but also features a simplified, durable, and pressure-resistant structure, making it less susceptible to pressure variations within the inner liner 2 that affect its sealing performance. It effectively counteracts the effects of thermal expansion and contraction and temperature on the material while maintaining a secure seal.

[0037] It should be noted that all the elastic soft rubbers used in this application are silicone.

[0038] The bubble-shaped elastic soft rubber 22 is in the form of a tubular bubble, a block bubble, or a capsule-shaped bubble; the bubble-shaped elastic soft rubber 22 is in the shape of a round tube, and the round tube-shaped bubble-shaped elastic soft rubber 22 is curved and connected at the head and tail to form a ring tube.

[0039] The cylindrical, bubble-shaped elastic soft rubber 22 is curved and connected end to end to form a ring tube. This design ensures the high stability and continuity of the inner liner 2 of the thermos. The ring tube shape not only effectively reduces the movement of the bubble-shaped elastic soft rubber 22, but also enhances the coherence of the overall structure, preventing breaks or gaps between the bubbles, thus ensuring that each part can perform its insulation function evenly.

[0040] The cylindrical, bubble-shaped elastic soft rubber 22 has a large contact area, effectively encapsulating the coolant and improving heat dissipation. The curved tubular design minimizes heat transfer paths and increases heat dissipation time during heat conduction, further enhancing insulation. Furthermore, the annular tube structure creates more uniform thermal resistance during heat transfer, further optimizing insulation performance.

[0041] Because the bubble-shaped elastic soft rubber 22 has a ring-shaped tubular structure, it can be evenly distributed within the inner liner 2, forming a tighter and more stable barrier. This structure not only helps improve its stability during long-term use but also effectively resists deformation. Especially in high or low temperature environments, the ring-shaped bubble-shaped elastic soft rubber 22 can better withstand external pressure and temperature changes, reducing structural damage or decreased insulation performance due to deformation and extending the lifespan of the thermos.

[0042] The diameter of the tubular bubble-shaped elastic soft rubber 22 is less than or equal to the distance between the two walls of the inner cavity of the inner liner 2; the cup body 1 is provided with a cup lid 4; and the liquid container 3 is one or more baby bottles arranged in a stacked manner.

[0043] The diameter of the cylindrical, bubble-shaped elastic soft rubber 22 is less than or equal to the distance between the two walls of the inner cavity of the inner liner 2. This design ensures that the bubble-shaped elastic soft rubber can fill the inner liner 2 evenly and maximize the use of the internal space. Because the size of the bubble-shaped elastic soft rubber 22 matches the distance of the inner cavity of the inner liner 2, it can effectively avoid the compression or uneven distribution of the bubbles, thereby enhancing the overall stability and ensuring good heat insulation performance in different usage environments.

[0044] Because the liquid containers 3 are stacked vertically and equipped with lids 4, the liquid can be more tightly contained between the multiple bottles, further improving insulation performance. The bubble-shaped elastic soft rubber 22 provides a heat insulation barrier, which, combined with the stacked design, better prevents external heat from entering the container, while also preventing liquid leakage or temperature loss, ensuring that the liquid maintains its temperature for a long time. The lid 4 further seals the container, preventing heat leakage or contamination.

[0045] This solution increases the container's capacity and functionality by using multiple stacked bottles, making it more adaptable to different needs. Multiple bottles can be stored separately. Furthermore, the lid design makes the container easy to carry and clean, and enhances its sealing properties, effectively preventing leaks and providing greater convenience and hygiene.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
