Description

Technical Field

[0001] This application relates to the field of tableware technology, and more specifically, to a detachable insulated tableware. Background Technology

[0002] Currently, ordinary tableware does not have a heat preservation effect. Especially when the external ambient temperature is low, the temperature of food will drop rapidly over time. Eating cold food can irritate the stomach and intestines, causing bloating, diarrhea, or indigestion.

[0003] To address the technical problem of food cooling rapidly due to ordinary tableware, which can cause bloating, diarrhea, or indigestion, tableware designed to maintain food within a specific temperature range, such as double-walled insulated bowls, can be used. These bowls typically consist of a detachable inner and outer bowl, with a water-filled space between them. The inner bowl is made of stainless steel, which enhances heat conduction efficiency, allowing the food inside to heat up quickly. However, because stainless steel is rigid and has limited elastic deformation, the water-filled space cannot be sealed by deformation of the inner bowl itself; therefore, further measures are needed. A flange is set at the opening of the inner bowl, forming an annular groove between the flange and the outer wall of the inner bowl. A sealing ring is engaged in the annular groove. After assembling the inner and outer bowls, the water-filled interlayer between the inner and outer bowls can be sealed by the deformation of the sealing ring. However, the sealing ring is prone to accumulating dirt during long-term use, which requires cleaning. Due to the narrow space inside the annular groove, the limited space provided to the operator for disassembling and installing the sealing ring results in difficulty in disassembling the sealing ring before cleaning, increasing the difficulty of cleaning, and the sealing ring may be misaligned after cleaning, causing sealing failure. Summary of the Invention

[0004] This application provides a detachable insulated tableware, which simplifies the cleaning process, eliminates the dead corner for dirt to hide in the closed fit between the annular groove and the sealing ring, thereby improving the cleaning effect and reducing the probability of misalignment or forgetting to install, thus improving the sealing effect.

[0005] Firstly, this application provides a detachable insulated tableware, including an inner bowl and an outer bowl. The inner bowl is made of an elastomeric material and has a sealing element. The sealing element and the inner bowl form an integral structure, and the sealing element is continuously arranged around the outer periphery of the inner bowl to form a closed loop structure. The inner bowl is housed within the outer bowl, which is made of a rigid material. The outer bowl has a sealing platform that seals against the sealing element. The sealing platform and the outer bowl form an integral structure, and the sealing platform is continuously arranged around the inner periphery of the outer bowl to form a closed loop structure. The inner bowl and the outer bowl are detachably and fixedly connected so that the sealing element abuts against the sealing platform to form a seal.

[0006] In the above technical solution, the core inventive concept of integrating the sealing element and inner bowl as a single structure, and the sealing platform and outer bowl as a single structure, directly integrates the sealing function into the body of the tableware. Compared with the existing technology that requires a separately set sealing ring and annular groove, this reduces the number of parts and simplifies the tableware structure. The inner bowl, made of elastomeric material, provides the sealing element with excellent elastic deformation capability, while the outer bowl, made of rigid material, provides sufficient support strength to the sealing platform. During the process of detachably fixing the inner and outer bowls, the sealing element undergoes uniform and controllable elastic deformation to ensure close contact between the sealing element and the sealing platform. The positioning of the sealing element and sealing platform forms a reliable circumferential surface seal, improving the sealing effect of the space between the outer and inner bowls. At the same time, it eliminates the closed sealing structure of separate sealing rings and annular grooves. Before washing, only the inner and outer bowls need to be separated to expose all sealing surfaces and the outer and inner bowls to the external environment, simplifying the washing steps, eliminating the dead corner of dirt accumulation in the closed fit gaps, and improving hygiene. It also reduces the probability of missing or misaligned sealing rings, improving sealing reliability.

[0007] In some embodiments, the seal includes a first sealing layer and a second sealing layer, with the first sealing layer disposed close to the sealing platform and the second sealing layer disposed away from the sealing platform along a first direction. The first seal is made of an elastomeric material and the second seal is made of a rigid material.

[0008] In some embodiments, the device further includes a first connector and a second connector, wherein the first connector and the inner bowl form an integrally formed structure, and the second connector and the outer bowl form an integrally formed structure, and the first connector and the second connector are detachably and fixedly connected.

[0009] In some embodiments, a first cavity is provided between the inner bowl and the outer bowl, and the inner bowl is made of silicone.

[0010] In some embodiments, the first connector includes a first threaded connector, and the second connector includes a second threaded connector, wherein the first threaded connector and the second threaded connector are threadedly engaged.

[0011] In some embodiments, the first threaded connector includes an integrally formed force-applying section and a vertical section. The force-applying section is for the user to hold. The vertical section includes a first surface near the outer wall of the inner bowl and a second surface away from the outer wall of the inner bowl. A first thread is provided on the second surface. The second threaded connector includes a second thread. The second thread is provided along the inner circumference of the outer bowl on the inner wall of the outer bowl. The first thread and the second thread are threadedly engaged.

[0012] In some embodiments, the first connector includes a first buckle, and the second connector includes a first locking block, wherein the first buckle and the first locking block engage with each other.

[0013] In some embodiments, along a first direction, the inner bowl includes a first opening and a first bottom disposed opposite to each other, the first opening having a first edge, the first edge being continuously disposed along the outer periphery of the first opening and forming a closed loop structure, the first edge being higher than the first connector.

[0014] In some embodiments, along a first direction, the inner bowl includes a first opening and a first bottom disposed opposite to each other, the first bottom being provided with a first suction cup.

[0015] In some embodiments, along a first direction, the wall of the outer bowl includes a thin-walled region and a thick-walled region arranged sequentially, and along a second direction, the thickness of the thin-walled region is T1, and the thickness of the thick-walled region is T2, satisfying T1≤T2, and the first direction and the second direction are perpendicular to each other.

[0024] Currently, ordinary tableware does not have a heat preservation effect. Especially when the external ambient temperature is low, the temperature of food will drop rapidly over time. Eating cold food can irritate the stomach and intestines, causing bloating, diarrhea, or indigestion.

[0025] To address the technical problem of food cooling rapidly due to ordinary tableware, which can cause bloating, diarrhea, or indigestion, tableware designed to maintain food within a specific temperature range, such as double-walled insulated bowls, can be used. These bowls typically consist of a detachable inner and outer bowl, with a water-filled space between them. The inner bowl is made of stainless steel, which enhances heat conduction efficiency, allowing the food inside to heat up quickly. However, because stainless steel is rigid and has limited elastic deformation, the water-filled space cannot be sealed by deformation of the inner bowl itself; therefore, further measures are needed. A flange is set at the opening of the inner bowl, forming an annular groove between the flange and the outer wall of the inner bowl. A sealing ring is engaged in the annular groove. After assembling the inner and outer bowls, the water-filled interlayer between the inner and outer bowls can be sealed by the deformation of the sealing ring. However, the sealing ring is prone to accumulating dirt during long-term use, which requires cleaning. Due to the narrow space inside the annular groove, the limited space provided to the operator for disassembling and installing the sealing ring results in difficulty in disassembling the sealing ring before cleaning, increasing the difficulty of cleaning, and the sealing ring may be misaligned after cleaning, causing sealing failure.

[0026] Based on the above considerations, in order to solve the technical problems of the sealing ring being difficult to disassemble before cleaning due to the limited internal space of the groove, which increases the difficulty of cleaning, and the sealing ring failing due to misalignment after cleaning, this application provides a detachable insulated tableware, including an inner bowl and an outer bowl. The inner bowl is made of an elastomer material and has a sealing element. The sealing element and the inner bowl form an integral structure, and the sealing element is continuously arranged around the outer circumference of the inner bowl to form a closed ring structure. The inner bowl is housed within the outer bowl, which is made of a rigid material and has a sealing platform that seals with the sealing element. The sealing platform and the outer bowl form an integral structure, and the sealing platform is continuously arranged around the inner circumference of the outer bowl to form a closed ring structure. The inner bowl and the outer bowl are detachably and fixedly connected so that the sealing element abuts against the sealing platform to form a seal.

[0027] In this type of detachable insulated tableware, a sealing element is integrated into the inner bowl, making it a component of the inner bowl. Simultaneously, a sealing platform is integrated into the outer bowl, forming a sealing unit that seals with the sealing element. This integration of the sealing element and the sealing platform into the outer bowl further simplifies the structure compared to existing water-filled tableware which requires separate sealing rings and mounting grooves. Furthermore, the sealing element... A closed ring structure is continuously arranged around the outer circumference of the inner bowl, and a sealing platform is continuously arranged around the inner circumference of the outer bowl, also forming a closed ring structure. This ensures that the sealing area formed between the sealing element and the sealing platform completely covers the space between the inner and outer bowls circumferentially. The inner bowl is made of an elastomer material, which has good elastic deformation. Since the sealing element is a component of the inner bowl, it also has good elastic deformation. The outer bowl is made of a rigid material, which has good supporting strength. Since the sealing platform is a component of the outer bowl, it also has good supporting strength. Thus, when the inner... When the inner and outer bowls are detachably and fixedly connected so that the sealing element abuts against the sealing platform to form a seal, the sealing element has good elastic deformation, and the sealing platform has good supporting strength. Therefore, the sealing platform can provide good support for the sealing element, making it easier for the sealing element to undergo elastic deformation and make close contact with the sealing platform under external force. In this way, the circumferential sealing range coverage and close contact ensure the sealing effect of the space between the inner and outer bowls. Finally, because the sealing structure composed of the sealing element and the sealing platform integrates the sealing function into the inner and outer bowls, it eliminates the need for a separately set sealing ring and the sealing structure formed by the annular groove compared to existing water-filled tableware. This design allows for easy cleaning by simply disassembling and reassembling the detachable inner and outer bowls, exposing the seals, sealing platform, and both the inner and outer bowls to the external environment. Compared to existing technologies that require disassembling the sealing ring within a narrow annular groove before cleaning, this simplifies the cleaning process and eliminates the dirt-trapping gap between the annular groove and the sealing ring, thus improving the cleaning effect. Furthermore, after cleaning, simply reassembling the inner and outer bowls achieves the sealing effect of the seals and sealing platform. Compared to existing technologies, installing the sealing ring within a narrow annular groove reduces the probability of misalignment or forgetting to install it, further enhancing the sealing effect.

[0028] Please refer to Figure 1-5 , Figure 1 Schematic diagrams of the structure of detachable insulated tableware provided in some embodiments of this application; Figure 2 A schematic diagram of the structure of a detachable insulated tableware provided in some embodiments of this application (showing the lid); Figure 3A schematic diagram of the structure of a detachable insulated tableware provided in some embodiments of this application (showing the detached state); Figure 4 This application provides structural schematic diagrams of some embodiments of a detachable insulated tableware (showing the inner bowl and sealing element); Figure 5 This application provides structural schematic diagrams of a detachable insulated tableware according to some embodiments (showing an outer bowl and a sealing platform). This application provides a detachable insulated tableware, including an inner bowl 1 and an outer bowl 2. The inner bowl 1 is made of an elastomeric material and has a sealing element 11. The sealing element 11 and the inner bowl 1 form an integral structure, with the sealing element 11 continuously arranged around the outer periphery of the inner bowl 1 to form a closed loop. The inner bowl 1 is housed within the outer bowl 2, which is made of a rigid material. The outer bowl 2 has a sealing platform 21 that seals against the sealing element 11. The sealing platform 21 and the outer bowl 2 form an integral structure, with the sealing platform 21 continuously arranged around the inner periphery of the outer bowl 2 to form a closed loop. The inner bowl 1 and the outer bowl 2 are detachably and fixedly connected so that the sealing element 11 abuts against the sealing platform 21 to form a seal.

[0029] Please continue to refer to Figure 2 The detachable insulated tableware may also include a lid 5, which is detachably and fixedly connected to the inner bowl 1.

[0030] The inner bowl 1 is made of an elastomer material, which can be silicone, silicone rubber or TPE (thermoplastic elastomer), etc.; it can also be food-grade silicone, food-grade silicone rubber or food-grade TPE, etc.

[0031] The seal 11 and the inner bowl 1 form an integral structure. The seal 11 and the inner bowl 1 can be integrally injection molded to form an integral structure, or the seal 11 can be a component of the inner bowl 1.

[0032] The seal 11 can be an annular rib, an annular lip, an annular sealing strip, an annular flange, an annular step, multiple annular sealing ribs, or a beveled lip sealing structure.

[0033] The cross-sectional shape of the seal 11 can be U-shaped, V-shaped or arc-shaped.

[0034] Please continue to refer to Figure 3 and Figure 4 The sealing element 11 is continuously arranged around the outer periphery of the inner bowl 1 to form a closed ring structure. When viewed along the first direction X, the sealing element 11 completely covers the outer periphery of the inner bowl 1 in the circumferential direction.

[0035] Please continue to refer to Figure 3The inner bowl 1 is placed inside the outer bowl 2. This can be because the outer bowl 2 has a first receiving cavity 211, and the inner bowl 1 is completely placed inside the first receiving cavity 211 or partially placed inside the first receiving cavity 211.

[0036] The outer bowl 2 is made of rigid materials, which can include metallic rigid materials such as steel, aluminum, and stainless steel, as well as rigid plastics such as PC plastic and ABS plastic, and non-metallic rigid materials such as wood, glass, and ceramics.

[0037] The sealing platform 21 and the outer bowl 2 form an integral structure. The sealing platform 21 and the outer bowl 2 can be integrally injection molded to form an integral structure, or the sealing platform 21 can be a component of the outer bowl 2.

[0038] Please continue to refer to Figure 3 and Figure 5 The sealing platform 21 is continuously arranged around the inner circumference of the outer bowl 2 to form a closed ring structure. When viewed along the first direction X, the sealing platform 21 completely covers the inner circumference of the outer bowl 2 in the circumferential direction.

[0039] The sealing element 11 abuts against the sealing platform 21 to form a seal. This can be achieved by detachably and fixedly connecting the inner bowl 1 and the outer bowl 2, and then applying a force to the sealing element 11 along the first direction X, the second direction Y, or obliquely during the connection process, so that the sealing element 11 and the sealing platform 21 come into contact with each other and generate an interaction force between them.

[0040] Detachable insulated tableware can be used in different tableware scenarios. For example, the shape and size of the inner bowl 1 and the outer bowl 2 can be adjusted accordingly based on different application scenarios.

[0041] In this embodiment, firstly, a sealing element 11 is provided on the inner bowl 1, forming an integral structure with the inner bowl 1. This makes the sealing element 11 a component of the inner bowl 1. Simultaneously, a sealing platform 21 is provided on the outer bowl 2, which seals with the sealing element 11. The sealing platform 21 and the outer bowl 2 form an integral structure, making the sealing platform 21 a component of the outer bowl 2. Thus, by forming the sealing element 11 and the inner bowl 1 as an integral structure, and the sealing platform 21 and the outer bowl 2 as an integral structure, the sealing function is integrated into both the inner bowl 1 and the outer bowl 2. Compared to existing water-filled tableware, which requires separate sealing rings and mounting grooves to achieve a sealing function, this simplifies the tableware structure. Secondly, by... A closed ring structure is continuously arranged around the outer circumference of the inner bowl 1, and a closed ring structure is formed by continuously arranging the sealing platform 21 around the inner circumference of the outer bowl 2. This ensures that the sealing area formed between the sealing element 11 and the sealing platform 21 completely covers the space between the inner bowl 1 and the outer bowl 2 in the circumferential direction. The inner bowl 1 is made of an elastomer material, which has good elastic deformation. Since the sealing element 11 is a component of the inner bowl 1, it also has good elastic deformation. The outer bowl 2 is made of a rigid material, which has good supporting strength. Since the sealing platform 21 is a component of the outer bowl 2, it also has good supporting strength. When the inner bowl 1 and outer bowl 2 are detachably and fixedly connected so that the sealing element 11 abuts against the sealing platform 21 to form a seal, the sealing element 11 has good elastic deformation and the sealing platform 21 has good support strength. Therefore, the sealing platform 21 can provide good support for the sealing element 11, making it easier for the sealing element 11 to undergo elastic deformation and make close contact with the sealing platform 21 under external force. In this way, the circumferential sealing range coverage and close contact ensure the sealing effect of the space between the inner bowl 1 and the outer bowl 2. Finally, since the sealing structure composed of the sealing element 11 and the sealing platform 21 integrates the sealing function into the inner bowl 1 and the outer bowl 2, it eliminates the need for a separately set sealing ring and annular groove compared to existing water-filled tableware. The sealed structure allows for easy cleaning by simply disassembling the detachable inner bowl 1 and outer bowl 2 before cleaning. This exposes the seal 11, sealing platform 21, outer bowl 2, and inner bowl 1 to the external environment. Compared to existing technologies, which require disassembling the sealing ring in a narrow annular groove before cleaning, this simplifies the cleaning process and eliminates the dead corner where dirt can accumulate—the sealed joint between the annular groove and the sealing ring—thus improving the cleaning effect. Furthermore, after cleaning, simply detaching and fixing the inner bowl 1 and outer bowl 2 is sufficient to achieve the sealing effect of the seal 11 and sealing platform 21. Compared to existing technologies, installing the sealing ring in a narrow annular groove reduces the probability of misalignment and forgetting to install it, thus improving the sealing effect.

[0042] In summary, this embodiment integrates the sealing function directly into the body of the tableware by treating the sealing element 11 and the inner bowl 1 as an integral structure, and the sealing platform 21 and the outer bowl 2 as an integral structure. Compared with the prior art which requires a separately set sealing ring and annular groove, this reduces the number of parts and simplifies the tableware structure. The inner bowl 1, made of elastomeric material, provides the sealing element 11 with excellent elastic deformation capability, while the outer bowl 2, made of rigid material, provides the sealing platform 21 with sufficient support strength. During the process of detachably fixing the inner bowl 1 and the outer bowl 2, the sealing element 11 undergoes uniform and controllable elastic deformation. The deformation allows the seal 11 and the sealing platform 21 to make tight contact, and the position setting of the seal 11 and the sealing platform 21 forms a reliable circumferential surface seal, improving the sealing effect of the space between the outer bowl 2 and the inner bowl 1; at the same time, it eliminates the closed sealing structure of independent sealing rings and annular grooves. Before cleaning, only the inner bowl 1 and the outer bowl 2 need to be separated to expose all sealing surfaces and the outer bowl 2 and the inner bowl 1 to the external environment, simplifying the cleaning steps, eliminating the dead corner of dirt hiding in the closed fitting gap, and improving the hygiene of use; it also reduces the probability of sealing ring missing installation and installation misalignment, thus improving the sealing reliability.

[0043] In some embodiments, please refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of a detachable insulated tableware provided in some embodiments of this application (showing a first sealing layer and a second sealing layer). The sealing element 11 includes a first sealing layer 111 and a second sealing layer 112. Along a first direction X, the first sealing layer 111 is disposed close to the sealing platform 21, and the second sealing layer 112 is disposed away from the sealing platform 21. The first sealing layer 111 is made of an elastomeric material, and the second sealing layer 112 is made of a rigid material.

[0044] The first sealing layer 111 is made of an elastomer material, which can be silicone, silicone rubber or TPE (thermoplastic elastomer), etc.; it can also be food-grade silicone, food-grade silicone rubber or food-grade TPE, etc.

[0045] The second sealing layer 112 is made of a rigid material, which may include metallic rigid materials such as steel, aluminum, and stainless steel, as well as rigid plastics such as PC plastic and ABS plastic, or non-metallic rigid materials such as wood, glass, and ceramics.

[0046] In this embodiment, the sealing element 11 includes a first sealing layer 111 located near the sealing platform 21 and a second sealing layer 112 located away from the sealing platform 21. The first sealing layer 111 is made of an elastomeric material, and the second sealing layer 112 is made of a rigid material. Since the elastomeric material has good elastic deformation, the first sealing layer 111 also has good elastic deformation. At the same time, since the rigid material has good support strength, the second sealing layer 112 also has good support strength. In this way, during the process of detachably and fixedly connecting the inner bowl 1 and the outer bowl 2, the second sealing layer 112 and the sealing platform 21 on both sides of the first sealing layer 111 along the first direction can provide good support for the first sealing layer 111, so that the second sealing layer 112 can better transmit external force to the first sealing layer 111. Under the action of external force and with the support provided by the sealing platform 21, the first sealing layer 111 is more likely to deform and come into close contact with the sealing platform 21, further improving the sealing effect of the space between the outer bowl 2 and the inner bowl 1.

[0047] In some embodiments, please continue to refer to Figure 3 It also includes a first connector 3 and a second connector 4. The first connector 3 and the inner bowl 1 form an integral structure, and the second connector 4 and the outer bowl 2 form an integral structure. The first connector 3 and the second connector 4 are detachably and fixedly connected.

[0048] The first connector 3 and the inner bowl 1 form an integral structure. The first connector 3 and the inner bowl 1 can be integrally injection molded to form an integral structure, or the first connector 3 can be a component of the inner bowl 1.

[0049] The second connector 4 and the outer bowl 2 form an integral structure. The second connector 4 and the outer bowl 2 can be integrally injection molded to form an integral structure, or the second connector 4 can be a component of the outer bowl 2.

[0050] In this embodiment, a first connector 3 is provided on the inner bowl 1, and the first connector 3 and the inner bowl 1 form an integral structure, so that the first connector 3 is a component of the inner bowl 1. At the same time, a second connector 4 is provided on the outer bowl 2, and the second connector 4 and the outer bowl 2 form an integral structure, so that the second connector 4 is a component of the outer bowl 2. The first connector 3 and the second connector 4 are detachably and fixedly connected. In this way, by forming the first connector 3 and the inner bowl 1 into an integral structure and the second connector 4 and the outer bowl 2 into an integral structure, the connection function is integrated into the inner bowl 1 and the outer bowl 2. Compared with the existing water-filled tableware, which requires separate connection parts to achieve the connection function, the structure of the tableware is simplified.

[0051] In some embodiments, please refer to Figure 7 , Figure 7This is a structural schematic diagram (showing the assembled state) of a detachable insulated tableware provided in some embodiments of this application. A first cavity 6 is provided between the inner bowl 1 and the outer bowl 2, and the inner bowl 1 is made of silicone.

[0052] The first cavity 6 can also be filled with hot water, which heats the inner bowl and further improves the heat preservation effect.

[0053] Please refer to Figure 8 , Figure 8 This is a schematic diagram of the structure of a detachable insulated tableware provided in some embodiments of this application (showing the inlet and outlet). In the embodiment where hot water is injected into the first cavity 6, in order to facilitate the injection and discharge of hot water, an inlet and outlet 27 communicating with the interior of the first cavity 6 is provided on the wall of the outer bowl 2. Along the first direction X, the distance between the inlet and outlet 27 and the sealing platform 21 is L1, which satisfies 0.5cm≤L1≤2cm.

[0054] L1 can be 0.5cm, 0.6cm, 0.7cm, 0.8cm, 0.9cm, 1cm, 1.1cm, 1.2cm, 1.3cm, 1.4cm, 1.5cm, 1.6cm, 1.7cm, 1.8cm, 1.9cm, 2cm, etc., or within a range consisting of any two of the above values.

[0055] By setting the distance L1 between the inlet / outlet 27 and the sealing platform 21 to satisfy 0.5cm≤L1≤2cm, the area between the inlet / outlet 27 and the sealing platform 21 is used as the water level limiting area. When adding water, the water volume can be better controlled, reducing the probability that the water in the first cavity 6 will overflow the sealing platform 21 when the inner bowl 1 is installed inside the outer bowl 2.

[0056] In this embodiment, by setting a first cavity 6 between the inner bowl 1 and the outer bowl 2, and setting the inner bowl 1 to be made of silicone, air can be injected into the first cavity 6. Since air and silicone rubber have relatively low thermal conductivity, the rate at which the heat of the food in the inner bowl 1 decreases can be effectively reduced through such a two-layer thermal barrier.

[0057] In some embodiments, please refer to Figure 9 , Figure 9 for Figure 7 A partially enlarged schematic diagram at point A. The first connecting member 3 includes a first threaded connecting member 31, and the second connecting member 4 includes a second threaded connecting member 41. The first threaded connecting member 31 and the second threaded connecting member 41 are threadedly engaged.

[0058] In this embodiment, a first threaded connector 31 and a second threaded connector 41 with mutual threaded engagement are firstly provided and secondly provided on the inner cup 1 and outer cup 2 respectively. This threaded engagement enables a detachable and fixed connection between the inner cup 1 and the outer cup 2. Secondly, since the threaded pair between the first threaded connector 31 and the second threaded connector 41 has a coaxial positioning function, it can guide the inner cup 1 and the outer cup 2 to be aligned during assembly, so that the sealing element 11 and the sealing platform 21 are accurately aligned, reducing the probability of positional misalignment between the sealing structures. At the same time, since the threaded engagement is a progressive locking structure, a clamping force along the first direction X can be gradually applied to the sealing element 11 during the screwing process. Combined with the elastomeric material of the sealing element 11 and the rigid material of the sealing platform 21, the sealing element 11 can produce uniform elastic deformation, which fully fills the tiny gaps between the sealing platforms 21.

[0059] In some embodiments, please continue to refer to Figure 3 and Figure 9 The first threaded connector 31 includes an integrally formed force-applying section 311 and a vertical section 312. The force-applying section 311 is for the user to hold. The vertical section 312 includes a first surface 3121 near the outer wall of the inner bowl 1 and a second surface 3122 away from the outer wall of the inner bowl 1. A first thread 31221 is provided on the second surface 3122. The second threaded connector 41 includes a second thread 411. The second thread 411 is provided along the inner circumference of the outer bowl 2 on the inner wall of the outer bowl 2. The first thread 31221 and the second thread 411 are threadedly engaged.

[0060] If the first threaded connector 31 is only provided on one side of the outer wall of the inner bowl 1, lateral force is easily generated when the first thread 31221 and the second thread 411 are tightened, which can easily cause the inner bowl 1 to shift and tilt, resulting in uneven local pressure on the sealing element 11 and the appearance of sealing gaps. Therefore, the first threaded connector 31 can be set as two, and the two first threaded connectors 31 are symmetrically arranged on the outer wall of the inner bowl 1, thus forming a symmetrical double-point layout structure. When the first thread 31221 and the second thread 411 are tightened, the first threads 31221 located on both sides are simultaneously subjected to force, thereby constraining both sides of the inner bowl 1, so that the inner bowl 1 and the outer bowl 2 always remain coaxial, thereby making the pressure distribution of the sealing element 11 uniform and able to completely abut against the sealing platform 21, reducing the probability of gaps between the sealing element 11 and the sealing platform 21, and further improving the sealing effect.

[0061] The force-applying section 311 can be a recessed or raised structure, or it can be a handle. The outer contour shape of the handle can be curved or circular.

[0062] The first threaded connector 31 can be fixedly connected to the outer wall surface of the inner bowl 1 by methods such as overmolding, insert molding, thermoforming, or bonding. In embodiments using overmolding, insert molding, or thermoforming, since the first threaded connector 31 and the inner bowl 1 form an integral structure through overmolding, insert molding, or thermoforming, there is no gap between the first threaded connector 31 and the outer surface of the inner bowl 1, further eliminating dead corners for dirt accumulation and improving cleaning convenience.

[0063] The second surface 3122 is provided with a first thread 31221, which can be along the first direction X, with the first thread 31221 partially covering the second surface 3122, or along the first direction X, with the first thread 31221 completely covering the second surface 3122.

[0064] The second thread 411 is provided on the inner wall surface of the outer bowl 2 along the inner circumference of the outer bowl 2. The second thread 411 can be provided on the inner wall surface of the outer bowl 2 without interruption along the inner circumference of the outer bowl 2, or the second thread 411 can be provided on the inner wall surface of the outer bowl 2 at intervals along the inner circumference of the outer bowl 2. The position of the second thread 411 corresponds one-to-one with the position of the first thread 31221.

[0065] In this embodiment, the first threaded connector 31 includes an integrally formed force-applying section 311 and a vertical section 312. The force-applying section 311 is used for the user to hold the tableware, and the vertical section 312 is provided with a first thread 31221 that is threadedly engaged with the second thread 411. In this way, the user can hold the tableware through the force-applying section 311 and use the force-applying section 311 as a force-applying part to tighten or loosen the threaded connection when assembling or disassembling the tableware. At the same time, the threaded engagement of the first thread 31221 and the second thread 411 enables a detachable fixed connection between the outer bowl 2 and the inner bowl 1. Thus, the inner bowl 1, which integrates the first threaded connector 31, has both hand-holding and threaded connection functions, eliminating the need for additional independent handles, threaded seats, and other parts, further reducing the number of tableware components.

[0066] In some embodiments, please refer to Figure 10 and Figure 11 , Figure 10 A schematic diagram of the structure of a detachable insulated tableware provided in some other embodiments of this application (showing the detached state); Figure 11 Schematic diagrams of the structure of detachable insulated tableware provided in other embodiments of this application (showing the assembled state). The first connector 3 includes a first buckle 32, and the second connector 4 includes a first locking block 42, the first buckle 32 and the first locking block 42 engaging with each other.

[0067] There are four first buckles 32 and four first blocks 42. The four first buckles 32 are fixedly connected to the outer wall of the inner bowl 1 and are evenly and spaced along the outer periphery of the inner bowl 1. The four first blocks 42 are fixedly connected to the outer wall of the outer bowl 2 and are respectively corresponding to the four first buckles 32. The first buckles 32 and the first blocks 42 are engaged and cooperated.

[0068] If a single-point or two-point snap-fit ​​is used, the locking force is concentrated in a local position, which can easily cause the inner bowl 1 to shift in position due to the force, resulting in uneven local pressure on the sealing element 11 and the appearance of sealing gaps. Therefore, by setting four first snap-fits 32 and evenly spaced along the outer wall of the inner bowl 1, and four first snap-fit ​​blocks 42 and corresponding to the first snap-fits 32 on the outer wall of the outer bowl 2, the four sets of first snap-fits 32 and first snap-fit ​​blocks 42 are engaged to form four evenly distributed snap-fit ​​points along the circumference between the inner bowl 1 and the outer bowl 2. After snap-fit, the locking force applied along the first direction X is distributed to the entire circumference, forming a circumferential constraint on the inner bowl 1, so that the inner bowl 1 and the outer bowl 2 always remain coaxial, thereby making the pressure distribution of the sealing element 11 uniform and able to completely abut against the sealing platform 21, reducing the probability of gaps between the sealing element 11 and the sealing platform 21, and further improving the sealing effect.

[0069] In this embodiment, by setting the first connecting member 3 to include the first buckle 32 and the second connecting member 4 to include the first locking block 42, a detachable fixed connection between the inner bowl 1 and the outer bowl 2 is achieved through a snap-fit ​​engagement. This allows the sealing member 11 on the outer periphery of the inner bowl 1 to abut against the sealing platform 21 on the inner periphery of the outer bowl 2 to achieve a seal. Furthermore, since the snap-fit ​​engagement is a quick-release connection structure, it can achieve rapid engagement and disengagement through elastic deformation. That is, during assembly, the inner bowl 1 is placed inside the outer bowl 2, and the first buckle 32 and the first locking block 42 engage to complete the fixation. During disassembly, applying external force to release the snap-fit ​​limit allows for quick separation of the inner bowl 1 and the outer bowl 2. By setting the above connection structure, the tableware can be better suited for scenarios involving high-frequency cleaning and repeated use of tableware.

[0070] In some embodiments, please refer to Figure 12 , Figure 12 Figure 3 A schematic diagram of the inner bowl structure (showing the first edge). Along the first direction X, the inner bowl 1 includes a first opening 12 and a first bottom 13 disposed opposite to each other. The first opening 12 is provided with a first edge 121, which is continuously disposed along the outer periphery of the first opening 12 and forms a closed ring structure. The first edge 121 is higher than the first connecting member 3.

[0071] Please continue to refer to Figure 12The first edge 121 is higher than the first connector 3, which can be along the first direction X. The height of the first edge 121 from the first bottom 13 is H1, and the height of the first connector 3 from the first bottom 13 is H2, satisfying H1>H2.

[0072] In this embodiment, by continuously setting along the outer periphery of the first opening 12 along the first edge 121 to form a closed ring structure, the first edge 121 can form a physical barrier at the first opening 12, thereby blocking the complementary food, soup, etc. in the inner bowl 1. At the same time, since the first opening 12 is set higher than the first connector 3, the complementary food, soup, etc. in the inner bowl 1 can be reduced from flowing onto the first connector 3, thereby reducing the probability of the threaded part on the first connector 3 coming into contact with stains and further improving the convenience of cleaning.

[0073] In some embodiments, please refer to Figure 13 , Figure 13 for Figure 3 A schematic diagram of the inner bowl structure (showing the first suction cup). Along the first direction X, the inner bowl 1 includes a first opening 12 and a first bottom 13 disposed opposite to each other, and a first suction cup 14 is provided on the first bottom 13.

[0074] The first bottom 13 is provided with a first suction cup 14, which can be integrally injection molded with the inner bowl 1. This eliminates the need to configure a separate suction cup base for the inner bowl 1, further reducing the number of parts in the tableware.

[0075] Please refer to Figure 14 , Figure 14 for Figure 3 A schematic diagram of the structure of the outer and middle bowls (showing the second suction cup). Along the first direction X, the outer bowl 2 includes a second opening 28 and a second bottom 29 disposed opposite to each other, and a second suction cup 210 is provided on the second bottom 29.

[0076] The second bottom 29 is provided with a second suction cup 210, which can be integrally injection molded with the outer bowl 2. This eliminates the need to configure a separate suction cup base for the outer bowl 2, further reducing the number of parts in the tableware.

[0077] In this embodiment, by providing a first suction cup 14 on the first bottom 13, when the inner bowl 1 needs to be used alone, the inner bowl 1 can be attached to the table by the first suction cup 14, thereby reducing the probability of the inner bowl 1 being displaced or tipped over under the action of external force.

[0078] In some embodiments, please refer to Figure 15 , Figure 15 for Figure 3A schematic diagram of the structure of the inner and outer bowls (showing the thin-walled and thick-walled regions). Along the first direction X, the wall of the outer bowl 2 includes a thin-walled region 22 and a thick-walled region 23 arranged sequentially. Along the second direction Y, the thickness of the thin-walled region 22 is T1, and the thickness of the thick-walled region 23 is T2, satisfying T1≤T2. The first direction X and the second direction Y are perpendicular to each other.

[0079] In this embodiment, firstly, by setting the wall of the outer bowl 2 along the first direction X to include a thin-walled region 22 and a thick-walled region 23 and limiting T1≤T2, the thick-walled region 23 protrudes from the thin-walled region 22 at the connection position along the second direction Y. This protruding area can be used to form a sealing platform 21, thereby facilitating the formation of the sealing platform 21. Secondly, the differentiated wall thickness design achieves functional zoning optimization: the thick-walled region 23 can improve its heat insulation capacity through its thicker wall thickness, reducing the rate at which heat diffuses outward from the first cavity 6. The thicker wall thickness can also improve the overall structural strength and load-bearing capacity of the outer bowl 2. The thin-walled region 22 does not have high strength stress and heat insulation requirements, and reducing the wall thickness can directly reduce the material usage and overall weight of the outer bowl 2.

[0080] In some embodiments, please refer to Figure 16 , Figure 16 for Figure 3 A schematic diagram of the structure of the outer and middle bowls (showing the vacuum cavity). Along the second direction Y, the outer bowl 2 includes a first shell 24 and a second shell 25 arranged sequentially, with a vacuum cavity 26 formed between the first shell 24 and the second shell 25.

[0081] In this embodiment, by setting up a vacuum cavity 26, a vacuum environment is formed between the two shell layers of the outer bowl 2. In this vacuum environment, there is almost no air medium, thus blocking the heat transfer paths of air conduction and convection. Compared to a solid wall structure, the thermal resistance of the vacuum cavity 26 is significantly increased. This makes it difficult for heat inside the first cavity 6 to dissipate outward through the outer bowl 2, maintaining the food temperature for a longer period while reducing the temperature of the outer wall surface of the outer bowl 2, thereby reducing the probability of the user being burned.

[0082] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0083] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
