Description

Technical Field

[0001] This utility model relates to the field of containers, specifically to an insulated container. Background Technology

[0002] Currently, most insulated containers on the market have relatively large openings at the top for convenient food storage, which makes it easy for heat to escape quickly from the container, resulting in poor insulation. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a heat-insulating container with good heat preservation effect.

[0004] One embodiment of the present invention provides a heat-insulating container, which includes: a container body; a lid body that covers the top opening of the container body, the lid body having a trigger key that, when pressed, causes the lid body to spring upward relative to the container body; and a heat-insulating cover that extends into the top opening of the container body and is located below the lid body, the heat-insulating cover having a first vacuum heat-insulating layer inside.

[0005] The insulated container provided in this embodiment includes a separate lid body and an insulated lid. This design facilitates the separate processing and shaping of each component. Furthermore, any upward heat transfer from the container's interior is hindered by both the insulated lid and the lid body, resulting in excellent insulation. The insulated lid also incorporates a first vacuum insulation layer, further enhancing the insulation effect. This first vacuum insulation layer extends to a certain depth within the container, reducing the likelihood of heat leakage and improving insulation performance. Additionally, the first vacuum insulation layer prevents significant heat transfer from the container to the lid body, effectively reducing the risk of burns to the user and improving product safety. Moreover, the lid body can be easily opened by pressing the trigger button, allowing for convenient opening.

[0006] Furthermore, in some embodiments, a second vacuum insulation layer is provided inside both the side wall and the bottom wall of the container, and the first vacuum insulation layer and the second vacuum insulation layer together enclose and form an insulation space.

[0007] In these embodiments, not only is there a vacuum insulation layer inside the heat insulation cover, but there is also a vacuum insulation layer inside the container. The second vacuum insulation layer inside the container and the first vacuum insulation layer inside the heat insulation cover together enclose the heat insulation space inside the container. This is beneficial for achieving all-round heat insulation inside the heat insulation space and improving the heat insulation effect of the heat insulation container.

[0008] Furthermore, in some embodiments, the heat insulation cover is fixedly connected to or detachably connected to the cover body.

[0009] In these embodiments, by connecting the heat-insulating cover to the cover body, the cover body and the heat-insulating cover can be moved synchronously when the cover is closed and opened, making operation convenient. Furthermore, it facilitates pressing down the cover body to insert the heat-insulating cover into the container to a certain depth.

[0010] Furthermore, if the heat insulation cover can be fixedly connected to the cover body, the connection is secure and they can be moved synchronously. If the heat insulation cover and the cover body are detachably connected, it facilitates separate cleaning and replacement of the heat insulation cover and the cover body. Of course, when users want to accelerate the cooling rate, they can also leave the heat insulation cover out and only cover the cover body. This can prevent external dust from entering the container and accelerate the cooling rate, meeting various user needs and improving the user experience.

[0011] Furthermore, in some embodiments, the heat-insulating cover is detachably connected to the inner surface of the side wall of the container body.

[0012] In these embodiments, the heat-insulating cover is connected to the side wall of the container body, eliminating the need for a connecting structure on the cover body to connect the heat-insulating cover, thus simplifying the cover body structure. Furthermore, the heat-insulating cover can be relatively independent of the cover body, facilitating separate cleaning and replacement of both the heat-insulating cover and the cover body, and allowing for easy removal of the heat-insulating cover to be used alone on the cover body, improving the user experience.

[0013] Furthermore, in some embodiments, the bottom of the cover body has connecting ribs circumferentially distributed around the centerline of the container body, and the heat-insulating cover is connected to the connecting ribs. This simplifies the manufacturing process of the cover body by requiring only a connecting structure on the connecting ribs to connect with the heat-insulating cover. Moreover, the design of the connecting ribs also allows the heat-insulating cover to extend further into the container body, improving the insulation effect.

[0014] Furthermore, in some embodiments, the upper part of the heat insulation cover is connected to the inner wall of the connecting rib, and the lower part of the heat insulation cover protrudes outward circumferentially from the connecting rib; and / or the outer wall of the connecting rib is provided with a sealing element that can fit tightly against the inner surface of the side wall of the container body.

[0015] In these embodiments, if the inner wall of the connecting rib is connected to the heat insulation cover and the outer wall of the connecting rib is connected to the sealing element, this satisfies both the connection between the cover body and the heat insulation cover and the sealing element seals the gap between the cover body and the side wall of the container body. This ensures that even if heat inside the container flows upward through the gap between the heat insulation cover and the container body, it can be quickly blocked by the sealing element, resulting in good heat preservation. Furthermore, making the lower part of the heat insulation cover circumferentially protrude outward from the connecting rib reduces the gap between the heat insulation cover and the side wall of the container body, thus reducing heat leakage.

[0016] Furthermore, in some embodiments, one of the connecting ribs and the heat insulation cover is provided with a slot, and the other is provided with a retaining rib, which is engaged in the slot. The structure is simple, easy to process, and easy to assemble.

[0017] Furthermore, in some other embodiments, the connecting rib is provided with a first connecting thread, and the heat insulation cover is provided with a second connecting thread. The connecting rib and the heat insulation cover are screwed together by the first and second connecting threads. The connection is firm and easy to assemble and disassemble. Moreover, it can prevent moisture and other substances inside the container from entering between the cover body and the heat insulation cover through the assembly gap between the heat insulation cover and the connecting rib.

[0018] Furthermore, in some embodiments, a sealing element is provided on the outer periphery of the lid body, which is used to tightly fit against the inner surface of the side wall of the container body. The sealing element can seal the gap between the lid body and the side wall of the container body, so that even if heat inside the container flows upward through the gap between the heat-insulating lid and the container body, it can be quickly blocked by the sealing element, resulting in good heat preservation.

[0019] Furthermore, in some embodiments, the lid body has a hollow mounting cavity, and a trigger key is disposed on the lid body; the insulated container also includes: a locking component, movably disposed in the mounting cavity, the cavity wall of the mounting cavity being provided with a clearance opening, the locking component being able to extend out of the clearance opening and engage with the container body; a spring-loaded component, retractably disposed on the lid body, for abutting against the container body; wherein, during the process of the lid body closing on the container body, the spring-loaded component can be compressed by the container body and clear the clearance opening, thereby enabling the locking component to extend out of the clearance opening and engage with the container body; the locking component can also be moved to the unlocked position under the action of the trigger key, thereby enabling the spring-loaded component to extend and lift the lid body.

[0020] In these embodiments, the insulated container uses a locking assembly to lock the lid body and the container body together, which helps the lid body to be stably closed on the container body. Moreover, when the lid body is closed on the container body and the locking assembly is engaged with the container body, the spring-loaded assembly is in a compressed state between the lid body and the container body, applying an upward elastic force to the lid body. Therefore, when it is necessary to open the lid, simply press the trigger button to move the locking assembly to the unlocked position, and the spring-loaded assembly can quickly lift the lid body according to its own elastic force, which makes it easy for the user to lift the lid body away from the container body and open the lid conveniently.

[0021] In addition, when the spring-loaded component lifts the cover body, it also moves the locking component on the cover body upward, moving the locking component away from the locked position. This prevents the locking component from relocking and affecting the opening of the cover, ensuring that the user can open the cover smoothly.

[0022] Furthermore, in some embodiments, when the spring-loaded assembly extends to lift the cover body, it can also block the clearance opening. This conceals the locking assembly, improves the aesthetics, and prevents dust and other impurities from entering the mounting cavity through the clearance opening.

[0023] Furthermore, in some embodiments, the cover body includes an outer cover and an inner cover, the inner cover is disposed inside the outer cover, the mounting cavity is located inside the inner cover, and the spring-loaded assembly is located outside the inner cover. During the process of squeezing the spring-loaded assembly at the opening of the container body, the inner cover extends into the container body and moves into the interior of the container body.

[0024] In these embodiments, the locking component is located inside the inner cover, preventing large-area exposure, resulting in a pleasing appearance and reducing the risk of contamination. Furthermore, in this configuration, the clearance opening can be located on the side wall of the inner cover, while the spring-loaded component is located on the outside, facilitating external blocking of the clearance opening and consequently, the locking component. Additionally, allowing the inner cover to extend further into the container body with the compression of the spring-loaded component increases the insertion depth of the cover body into the container opening, thereby improving sealing and insulation.

[0025] Furthermore, in some embodiments, the rebound assembly includes an elastic element and an annular pressing element. One end of the elastic element is connected to the cover body, and the annular pressing element is connected to the other end of the elastic element. The annular pressing element is used to abut against the container body. The annular pressing element is provided with a blocking part, which blocks the clearance opening when the locking assembly is in the unlocked position.

[0026] In these embodiments, the spring-loaded assembly includes an annular pressing member that circumferentially presses against the container body, so that when the lid body is closed on the container body, the spring-loaded assembly can be circumferentially compressed evenly, and after the locking assembly is unlocked, the spring-loaded assembly can circumferentially support the container body, thereby stably lifting the lid body, and the spring-loaded process is stable and reliable.

[0027] Furthermore, in some embodiments, there are two trigger keys arranged side by side in the mounting cavity. The locking assembly includes two latches and a spring. The two latches are respectively connected to the opposite sides of the two trigger keys, and the spring is disposed between the two trigger keys. The latches can extend out of the mounting cavity under the elastic force of the spring to engage with the container body. The top wall of the cover body has an opening corresponding to the position of the two trigger keys. The tops of the two trigger keys are exposed through the opening and can move closer to each other under the action of external force, so that the latches can move into the mounting cavity.

[0028] In these embodiments, when the lid body is placed on the container body, as long as the lid body is pressed down into place, the locking tongue connected to the two trigger buttons will automatically extend out of the receiving cavity under the elastic force of the spring to engage with the container body, without requiring additional operation of the locking components by the user, making lid closing convenient. When it is necessary to unlock, simply pinch the two trigger buttons to move the two locking tongues to the unlocked position away from the container body, making operation convenient.

[0029] Other aspects and / or advantages of the present invention will be set forth in part in the description which follows, and in part will be clear from the description or may be learned by practice of the present invention. Attached Figure Description

[0040] The following will combine Figures 1 to 8 This invention introduces an insulated container provided by an embodiment of the present invention.

[0041] like Figures 1 to 3 As shown, one embodiment of the present invention provides a heat-insulating container, which includes: a container body 10; a lid body 20, which covers the top opening of the container body 10, and the lid body 20 is provided with a trigger key 260, which can cause the lid body 20 to spring upward relative to the container body 10 when the trigger key 260 is pressed; and a heat-insulating cover 30, which extends into the top opening of the container body 10 and is located below the lid body 20, and the heat-insulating cover 30 has a first vacuum heat-insulating layer 310 inside.

[0042] The insulated container provided in this embodiment includes a separate lid body 20 and a heat-insulating lid 30. This design facilitates the separate processing and shaping of each component. Furthermore, if heat from inside the container body 10 were to be transferred upwards, it would be effectively blocked by both the heat-insulating lid 30 and the lid body 20, resulting in excellent heat preservation. Moreover, the heat-insulating lid 30 also has a first vacuum insulation layer 310 inside, which further enhances the heat preservation effect. The first vacuum insulation layer 310 extends into the container body 10 to a certain depth, reducing the likelihood of heat leakage and improving the heat preservation effect. In addition, due to the obstruction of the first vacuum insulation layer 310, very little heat from inside the container body 10 is transferred to the lid body 20 located above, effectively reducing the chance of users being burned by the surface of the lid body 20 and improving product safety. Furthermore, the lid body 20 can be easily opened by pressing the trigger button 260, allowing for direct upward pop-up.

[0043] Figure 3 The diagram shows a longitudinal cross-sectional view of the lid body 20 when it springs upward relative to the container body 10. When the heat-insulating lid 30 is connected to the lid body 20, the lid body 20 can move the heat-insulating lid 30 upward synchronously, making it convenient for the user to open the lid.

[0044] Furthermore, in some embodiments, such as Figure 1 As shown, a second vacuum insulation layer 130 is provided in both the side wall 110 and the bottom wall 120 of the container body 10. The first vacuum insulation layer 310 and the second vacuum insulation layer 130 together enclose and form an insulation space.

[0045] In these embodiments, not only does the heat insulation cover 30 have a vacuum insulation layer, but the container body 10 also has a vacuum insulation layer. The second vacuum insulation layer 130 inside the container body 10 and the first vacuum insulation layer 310 inside the heat insulation cover 30 together enclose the heat insulation space inside the container body 10. This is beneficial for achieving all-round heat insulation inside the heat insulation space and improving the heat insulation effect of the heat insulation container.

[0046] It should be noted that the container body 10 of this application is the same as the prior art, which is formed by the side wall 110 and the bottom wall 120 to form a receiving cavity with an opening at the top. Therefore, those skilled in the art can understand that the heat preservation space is actually part of the receiving cavity.

[0047] Furthermore, such as Figure 1 As shown, the second vacuum insulation layer 130 can extend to the top of the side wall 110 of the container body 10, and the depth H of the first vacuum insulation layer 310 extending into the top opening of the container body 10 ranges from 5mm to 30mm. The first vacuum insulation layer 310 extends deep enough into the container body 10, below the highest point of the second vacuum insulation layer 130 by a certain distance, resulting in good heat preservation effect of the insulation space.

[0048] As an example, the depth H of the second vacuum insulation layer 130 extending into the top opening of the container body 10 can be 10mm, 15mm, 20mm, 30mm, etc.

[0049] Furthermore, in some embodiments, the heat insulation cover 30 is fixedly connected to or detachably connected to the cover body 20.

[0050] In these embodiments, the heat insulation cover 30 is connected to the cover body 20, so that the cover body 20 and the heat insulation cover 30 can be moved synchronously when the cover is closed and opened, which is convenient to operate. Moreover, it is convenient to press down the cover body 20 to extend the heat insulation cover 30 into the container body 10 to a certain depth. Furthermore, since the cover body 20 can be triggered to open, it can also move the heat insulation cover 30 upward together, so that even if negative pressure occurs in the heat-insulating space, the heat insulation cover 30 can be easily opened.

[0051] If the heat insulation cover 30 can be fixedly connected to the cover body 20, the connection is secure and they can move synchronously. If the heat insulation cover 30 and the cover body 20 are detachably connected, it is convenient to clean and replace the heat insulation cover 30 and the cover body 20 separately. Of course, if the user wants to accelerate the cooling speed, the heat insulation cover 30 can be omitted, and only the cover body 20 can be used. This can prevent external dust from entering the container 10 and accelerate the cooling speed, meeting various user needs and improving the user experience.

[0052] Furthermore, such as Figure 2 and Figure 3 As shown, when the heat-insulating cover 30 and the cover body 20 are detachably connected, a storage cavity 320 can be formed between the upper surface of the heat-insulating cover 30 and the lower surface of the cover body 20. The storage cavity 320 can be used to store tableware and other items, eliminating the need for users to place tableware separately. Of course, it can also be used to store other items, improving the user experience.

[0053] Specifically, the upper surface of the heat insulation cover 30 can be recessed downwards to increase the space of the storage cavity 320, making it convenient to store items of a certain volume. Alternatively, the lower surface of the cover body 20 can be recessed upwards to increase the space of the storage cavity 320. The space of the storage cavity 320 can also be increased by extending the length of the connecting rib 222.

[0054] Furthermore, in some other embodiments, the heat insulation cover 30 can be detachably connected to the inner surface of the side wall 110 of the container body 10.

[0055] In these embodiments, the heat insulation cover 30 is connected to the side wall 110 of the container body 10, eliminating the need for a connecting structure on the cover body 20 to connect the heat insulation cover 30, thus simplifying the structure of the cover body 20. Furthermore, the heat insulation cover 30 can be relatively independent of the cover body 20, facilitating separate cleaning and replacement of both the heat insulation cover 30 and the cover body 20, and allowing for easy removal of the heat insulation cover 30 to cover the cover body 20 separately, thereby improving the user experience.

[0056] As an example, a support rib (not shown in the figure) is provided on the inner surface of the side wall 110 of the container body 10, and the heat insulation cover 30 is placed on the support rib.

[0057] In this case, when the cover body 20 is placed on the top opening of the container body 10, the heat insulation cover 30 can be pressed downward to prevent the air pressure in the heat insulation space from rising and lifting the heat insulation cover 30, thus affecting the heat insulation effect.

[0058] Regarding the connection structure between the heat insulation cover 30 and the cover body 20, further, in some embodiments, such as Figures 2 to 4 As shown, the bottom of the cover body 20 has connecting ribs 222 that are circumferentially distributed around the center line of the container body 10 and protrude downwards. The heat insulation cover 30 is connected to the connecting ribs 222. In this way, only a connecting structure needs to be set on the connecting ribs 222 to connect with the heat insulation cover 30, making the cover body 20 easy to process. Moreover, the design of the connecting ribs 222 also facilitates the heat insulation cover 30 to extend further into the container body 10, improving the heat insulation effect.

[0059] Furthermore, in some embodiments, such as Figures 2 to 4 As shown, the upper part of the heat insulation cover 30 is connected to the inner sidewall 110 of the connecting rib 222, and the lower part of the heat insulation cover 30 protrudes outward from the connecting rib 222 in a circumferential direction; and / or the outer sidewall 110 of the connecting rib 222 is provided with a sealing element 250, which can be tightly fitted to the inner surface of the sidewall 110 of the container body 10.

[0060] In these embodiments, if the inner wall 110 of the connecting rib 222 is connected to the heat insulation cover 30, and the outer wall 110 of the connecting rib 222 is connected to the sealing element 250, this satisfies both the connection between the cover body 20 and the heat insulation cover 30 and the sealing element 250 seals the gap between the cover body 20 and the side wall 110 of the container body 10. Thus, even if heat inside the container body 10 flows upward through the gap between the heat insulation cover 30 and the container body 10, it can be quickly blocked by the sealing element 250, resulting in good heat preservation. Furthermore, by making the lower part of the heat insulation cover 30 circumferentially protrude outward from the connecting rib 222, the gap between the heat insulation cover 30 and the side wall 110 of the container body 10 can be reduced, thus reducing heat leakage.

[0061] As an example, seal 250 can be a silicone sealing ring, fitted onto connecting rib 222. It provides a good seal, and preferably uses food-grade silicone, ensuring no impact on user health.

[0062] The seal 250 may include a sealing ring body and at least one sealing rib located around the outer periphery of the sealing ring body. The sealing rib fits against the side wall 110 of the container body 10, resulting in a good sealing effect. Here, the sealing rib may extend obliquely downwards or obliquely upwards. Of course, the seal 250 may also have other structures, which are not listed in detail here.

[0063] Furthermore, in other embodiments, such as Figure 2 and Figure 4 As shown, the heat insulation cover 30 can also be connected to the outer wall 110 of the connecting rib 222. The sealing element 250 can also be provided on the outer periphery of the cover body 20 or the outer periphery of the heat insulation cover 30.

[0064] As an example, in the connecting rib 222 and the heat insulation cover 30, one of them can be provided with a slot 2221, and the other can be provided with a retaining rib 330, which is inserted into the slot 2221. The structure is simple, easy to process, and easy to assemble.

[0065] In this way, the retaining rib 330 can be made to have a certain degree of elasticity, or the groove wall of the retaining groove 2221 can be made to have a certain degree of elasticity, so that the retaining groove 2221 can hold the retaining rib 330 tightly, thereby improving the connection stability of the connecting rib 222 and the heat insulation cover 30.

[0066] As an example, such as Figure 2 and Figure 4 As shown, when a slot 2221 is provided on the connecting rib 222 and a retaining rib 330 is provided on the heat insulation cover 30, strong pressure can be used to snap the retaining rib 330 on the heat insulation cover 30 into the slot 2221 on the connecting rib 222. This causes the slot 2221 to contract and tighten around the retaining rib 330, and even causes the connecting rib 222 to tighten around the heat insulation cover 30, thus fixing the connection between the two. The heat insulation cover 30 and the connecting rib 222 are not detachable after assembly, and the connection is firm.

[0067] As an example, such as Figure 5 and Figure 6 As shown, the connecting rib 222 can be provided with a first connecting thread 2222, and the heat insulation cover 30 can be provided with a second connecting thread 340. The connecting rib 222 and the heat insulation cover 30 are screwed together by the first connecting thread 2222 and the second connecting thread 340. The connection is firm and easy to assemble and disassemble. Moreover, it can prevent water vapor and other substances inside the container body 10 from entering between the cover body 20 and the heat insulation cover 30 through the assembly gap between the heat insulation cover 30 and the connecting rib 222.

[0068] Of course, the heat insulation cover 30 and the connecting rib 222 can also be connected in other ways, not limited to the above embodiments. For example, the heat insulation cover 30 can also be connected to the connecting rib 222 by rotation and fastening, or by a pin connection, etc.

[0069] Furthermore, in some embodiments, such as Figure 2 , Figure 3 and Figure 6 As shown, a sealing element 250 is provided on the outer periphery of the cover body 20. The sealing element 250 is used to tightly fit with the inner surface of the side wall 110 of the container body 10. The sealing element 250 can seal the gap between the cover body 20 and the side wall 110 of the container body 10. In this way, even if the heat inside the container body 10 flows upward through the gap between the heat insulation cover 30 and the container body 10, it can be quickly blocked by the sealing element 250, resulting in good heat preservation effect.

[0070] Furthermore, in some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, the lid body 20 has a hollow mounting cavity 240, and a trigger key 260 is disposed on the lid body 20. The insulated container also includes: a locking component 270, which is movably disposed in the mounting cavity 240. The cavity wall of the mounting cavity 240 is provided with a clearance opening 241. The locking component 270 can extend out of the clearance opening 241 and engage with the container body 10. A spring-loaded component 280 is retractably disposed on the lid body 20 and is used to abut against the container body 10. During the process of the lid body 20 closing on the container body 10, the spring-loaded component 280 can be compressed by the container body 10 and clear the clearance opening 241, thereby allowing the locking component 270 to extend out of the clearance opening 241 and engage with the container body 10. The locking component 270 can also be moved to the unlocked position under the action of the trigger key 260, thereby allowing the spring-loaded component 280 to extend and lift the lid body 20.

[0071] In these embodiments, the insulated container uses locking assembly 270 to lock the lid body 20 and the container body 10 together, which helps the lid body 20 to be stably closed on the container body 10. Moreover, when the lid body 20 is closed on the container body 10 and the locking assembly 270 is engaged with the container body 10, the spring-loaded assembly 280 is in a compressed state between the lid body 20 and the container body 10, applying an upward elastic force to the lid body 20. Therefore, when it is necessary to open the lid, simply press the trigger button 260 to move the locking assembly 270 to the unlocked position, and the spring-loaded assembly 280 can quickly lift the lid body 20 according to its own elastic force, which helps the user to easily lift the lid body 20 away from the container body 10, making it convenient to open the lid.

[0072] In addition, when the spring-loaded component 280 lifts the cover body 20, it also moves the locking component 270 on the cover body 20 upward, so that the locking component 270 is away from the locked position. This can prevent the locking component 270 from relocking and affecting the opening of the cover, and ensure that the user can open the cover smoothly.

[0073] Furthermore, in some embodiments, such as Figure 3 As shown, when the spring-loaded assembly 280 extends and lifts the cover body 20, the spring-loaded assembly 280 can also block the clearance opening 241. This can hide the locking assembly 270, improve the appearance, and prevent dust and other impurities from entering the mounting cavity 240 through the clearance opening 241.

[0074] Furthermore, in some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, the cover body 20 includes: an outer cover 210; an inner cover 220 disposed inside the outer cover 210; an installation cavity 240 located inside the inner cover 220; and a spring-loaded assembly 280 located outside the inner cover 220. During the process of squeezing the spring-loaded assembly 280 at the opening of the container body 10, the inner cover 220 extends into the container body 10 and moves into the container body 10.

[0075] In these embodiments, the locking component 270 is located inside the inner cover 220, so that the locking component 270 is not exposed over a large area, resulting in a good appearance and resistance to contamination. Furthermore, in this case, the clearance opening 241 can be located on the side wall 110 of the inner cover 220, and the spring-loaded component 280 is located on the outside of the inner cover 220, facilitating the blocking of the clearance opening 241 from the outside, thereby blocking the locking component 270. In addition, allowing the inner cover 220 of the cover body 20 to extend further into the container body 10 with the compression of the spring-loaded component 280 increases the insertion depth of the cover body 20 into the opening of the container body 10, thereby improving sealing and heat preservation.

[0076] Furthermore, such as Figure 2 , Figure 3 and Figure 7 As shown, a limiting boss 221 can be provided on the outer side wall 110 of the inner cover 220. When the locking component 270 is in the locked position, the spring-loaded component 280 can be pushed away from the limiting boss 221 by the container body 10. When the locking component 270 is in the unlocked position, the spring-loaded component 280 can extend and press against the limiting boss 221.

[0077] This design allows the spring-loaded component 280 to extend and rebound until it abuts against the limiting boss 221. This limits the spring-loaded component 280's rebound length and the height it lifts the cover body 20, ensuring that the cover body 20 remains at the same height during multiple openings, resulting in a better user experience. Furthermore, the spring-loaded component 280 is positioned between the outer cover 210 and the limiting boss 221, reducing the likelihood of it falling off the cover body 20. Moreover, when the spring-loaded component 280 abuts against the limiting boss 221, it also simultaneously blocks the clearance opening 241, ensuring proper coverage.

[0078] As an example, such as Figure 3 and Figure 7 As shown, the limiting boss 221 is annular and distributed circumferentially around the inner cover 220.

[0079] As an example, the limiting boss 221 includes a plurality of sub-bosses that are circumferentially spaced around the inner cover 220.

[0080] Furthermore, in some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, the spring-loaded assembly 280 includes: an elastic member 281, one end of which is connected to the cover body 20; and an annular pressing member 282, which is connected to the other end of the elastic member 281. The annular pressing member 282 is used to abut against the container body 10. A blocking part 283 is provided on the annular pressing member 282. When the locking assembly 270 is in the unlocked position, the blocking part 283 blocks the clearance opening 241.

[0081] In these embodiments, the spring-loaded assembly 280 includes an annular pressing member 282, which circumferentially presses against the container body 10, so that when the lid body 20 is closed on the container body 10, the spring-loaded assembly 280 can be circumferentially compressed evenly. After the locking assembly 270 is unlocked, the spring-loaded assembly 280 can circumferentially support the container body 10, thereby stably lifting the lid body 20, and the spring-loaded process is stable and reliable.

[0082] Furthermore, the inner edge of the annular pressing member 282 can have a downwardly protruding annular rib, which forms a blocking portion 283, so that the outer diameter of the annular rib can match the inner diameter of the opening of the container body 10. Then, during the process of the container body 10 lifting the rebound assembly 280, the annular rib can limit the container body 10, which is beneficial for the smooth movement of the rebound assembly 280. Alternatively, the annular pressing member 282 can have a certain height, and the inner sidewall 110 of the annular pressing member 282 can be configured as a blocking portion 283 to block the clearance opening 241.

[0083] As an example, such as Figure 2 , Figure 3 and Figure 7As shown, a receiving groove 230 is formed between the inner wall 110 of the outer cover 210 and the outer wall 110 of the inner cover 220. Multiple elastic members 281 are distributed circumferentially along the annular pressing member 282. When the cover body 20 is placed on the container body 10, the opening of the container body 10 is inserted into the receiving groove 230 and presses upward against the annular pressing member 282. The annular pressing member 282 moves upward relative to the inner cover 220, the spring 272 is compressed and shortened, and then the locking assembly 270 engages with the container body 10, thus stably placing the cover body 20 on the container body 10. When opening the lid, the locking component 270 is first unlocked, releasing the snap-fit ​​relationship with the container body 10. The lower surface of the annular pressing member 282 abuts against the container body 10, the bottom end of the elastic member 281 abuts against the annular pressing member 282, and the top end extends to lift the outer cover 210, thereby lifting the inner cover 220 connected to the outer cover 210 and the locking component 270 connected to the lid body 20, so as to move the locking component 270 away from the snap-fit ​​position on the container body 10, making it easier to open the lid.

[0084] Furthermore, in some embodiments, such as Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, there are two trigger keys 260, which are arranged side by side in the mounting cavity 240. The locking assembly 270 includes: two locking tongues 271, which are respectively connected to the opposite sides of the two trigger keys 260; and a spring 272, which is disposed between the two trigger keys 260. The locking tongues 271 can extend out of the mounting cavity 240 under the elastic force of the spring 272 to engage with the container body 10. The top wall of the cover body 20 is provided with an opening 211 corresponding to the position of the two trigger keys 260. The tops of the two trigger keys 260 are exposed through the opening 211 and can move closer to each other under the action of external force so that the locking tongues 271 can move into the mounting cavity 240.

[0085] In these embodiments, when the lid body 20 is placed on the container body 10, as long as the lid body 20 is pressed down into place, the locking tongue 271 connected to the two trigger buttons 260 will automatically extend out of the receiving cavity under the elastic force of the spring 272 to engage with the container body 10, without requiring additional operation of the locking component 270 by the user, making lid closing convenient. When it is necessary to unlock, simply pinch the two trigger buttons 260 to move the two locking tongues 271 to the unlocked position away from the container body 10, making operation convenient.

[0086] As an example, such as Figure 2 and Figure 3 As shown, a locking groove 111 is provided on the inner surface of the side wall 110 of the container body 10, and the locking tongue 271 of the locking component 270 is engaged in the locking groove 111.

[0087] Furthermore, in some embodiments, such as Figure 4 As shown, the heat insulation cover 30 includes a first metal disc 351 and a second metal disc 352, which are joined together to form a first vacuum heat insulation layer 310. The first vacuum heat insulation layer 310, formed by the metal discs, has good high-temperature resistance and is not easily deformed. For example, the first metal disc 351 and the second metal disc 352 can be stainless steel discs.

[0088] Of course, the first vacuum insulation layer 310 can also be made of other materials, such as high-temperature resistant plastic, and is not limited to stainless steel.

[0089] Furthermore, in some embodiments, the insulated container can be an insulated pot or an insulated cup, etc.

[0090] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
