DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0031] Referring to Figures 1 to 7 , the silicone cover stainless steel lunch box comprises a stainless steel box body 1 and a silicone cover body 2 connected with the stainless steel box body 1, and the two opposite sides of the silicone cover body 2 are respectively provided with a first anti-scald part 21 and a second anti-scald part 22 extending downward.

[0032] The silicone cover stainless steel lunch box of the present application effectively reduces the heat transfer from the stainless steel box body to the cover body and the edge during the microwave heating process by providing the first anti-scald part and the second anti-scald part extending downward on the two opposite sides of the silicone cover body, thereby significantly reducing the risk of scalding when the user takes out the lunch box. At the same time, the matching connection of the silicone cover body and the stainless steel box body not only ensures the sealing property, but also has the characteristics of lightness and durability, thereby improving the safety and convenience of the lunch box during microwave heating.

[0033] Further, as a preferred embodiment of the present solution but not limited, the top edge of the silicone cover body 2 is provided with an arched protrusion 23 extending upward, and the arched protrusion 23 forms a stress surface 231 on the opposite side of the first anti-scald part 21 and the second anti-scald part 22, respectively.

[0034] In this embodiment, by setting an upwardly extending arched protrusion on the top edge of the silica gel cover body, and forming a stress surface opposite the first and second anti-scald parts on the arched protrusion, the structural strength of the silica gel cover body can be enhanced, and four force application parts can be provided when the user takes out the lunch box, which are the first anti-scald part and the stress surface, the second anti-scald part and the stress surface, the user can take out in the way of pinching with four fingers, while increasing the stress area, thereby increasing the friction, avoiding the inconvenience caused by the smooth surface of the cover body or high temperature; in addition, the arched protrusion can also play a certain heat insulation role, reducing the conduction of heat to the top of the cover body, thereby reducing the risk of scalding the user; in other possible embodiments, the shape of the arched protrusion can be designed as a wave shape or a structure with anti-slip texture.

[0035] Further, as a preferred embodiment of the present scheme but not limited, the first anti-scald part 21 and the second anti-scald part 22 are arranged as an arc shape, the maximum height of which is h, and the height of the silica gel cover body 2 is H, wherein h≥H.

[0036] In this embodiment, the overall structure can be coordinated and practical while ensuring the anti-scald effect; the arc design not only conforms to ergonomics, is convenient for the user to grip, but also effectively reduces the conduction of heat from the stainless steel box body to the edge of the cover body, thereby reducing the risk of scalding the user when taking out the lunch box; at the same time, by controlling the height of the anti-scald part to exceed the height of the cover body, the use of silica gel material can be reduced while ensuring the anti-scald effect, saving production costs and ensuring that the lunch box is more convenient to stack, store and carry; the arc surface of the anti-scald part can also be provided with anti-slip texture or adopt a double-layer silica gel structure to further improve the heat insulation performance, which not only solves the problem of over-heating of the edge of the traditional stainless steel lunch box after heating, but also enhances the user experience, especially suitable for scenes that need to heat and use food frequently, further improving the practicality and market competitiveness of the product.

[0037] Further, as a preferred embodiment of the present scheme but not limited, the top edge of the stainless steel box body 1 is provided with an outwardly turned arc-shaped flange 11, and the silica gel cover body 2 is provided with a connecting groove 24 for interference fit of the arc-shaped flange 11 to connect the silica gel cover body 2 and the stainless steel box body 1.

[0038] In this embodiment, by setting the outwardly turned arc-shaped edge on the top edge of the stainless steel box body and designing a connecting groove with interference fit on the silica gel cover, the tight connection between the silica gel cover and the stainless steel box body can be achieved, thereby effectively improving the sealing performance of the meal box and preventing food leakage during heating or carrying; the design of the arc-shaped edge not only enhances the structural strength of the top of the box body, but also provides a larger contact area during connection, making the combination between the silica gel cover and the box body more stable, while reducing wear caused by frequent opening and closing; in addition, the interference fit does not require additional locks or fixing devices, simplifying the structural design of the meal box, reducing production costs and improving the convenience of use.

[0039] Further, as a preferred embodiment of the present scheme but not limited, at least one rib 241 is arranged along the path of the connecting groove 24.

[0040] In this embodiment, the ribs are arranged along the path of the connecting groove, which can improve the sealing performance by increasing the local contact pressure, effectively preventing liquid leakage during heating or pouring of the meal box, and on the other hand, increasing the friction when the silica gel cover is separated from the stainless steel box body, thereby enhancing the connection stability between the two and avoiding accidental loosening of the cover due to external force or vibration; the design of the ribs can also compensate for the elastic decay of the silica gel material to some extent, prolonging the service life of the product; the working principle is that the ribs are tightly fitted with the arc-shaped edge of the stainless steel box body through interference fit, forming a multi-point contact sealing structure, while providing additional resistance when opening the cover, so that the user needs to exert more force to separate the cover from the box body, thereby ensuring safety during use; the ribs can be designed in a wavy, zigzag or inclined angle structure to further optimize the sealing effect and friction performance, and small protrusions can be added to the surface of the ribs or different hardness of silica gel materials can be used to meet different use requirements; not only can it solve the problems of insufficient sealing and easy loosening of the cover of traditional meal boxes, but also can improve the user's operation experience, further enhancing the practicality and market competitiveness of the product.

[0041] Further, as a preferred embodiment of the present scheme but not limited, the rib 241 is arranged on the inner wall of the connecting groove 24 and connected to the inner side of the arc-shaped edge 11.

[0042] In this embodiment, the rib is arranged at the connection between the inner wall of the connecting groove and the inner side of the arc-shaped flange. The position of the rib can be accurately positioned to maximize its functional effect, thereby improving the sealing performance and enhancing the connection stability between the silica gel cover and the stainless steel box body. When the rib is located at the connection between the arc-shaped flange and the inner side, it can effectively fill the small gap between the two, form a tighter contact, further prevent liquid or gas leakage, and provide additional resistance when the cover is opened, avoiding accidental loosening of the cover due to external force or vibration. The working principle is that the rib produces local pressure between the arc-shaped flange and the connecting groove through interference fit. This pressure not only enhances the sealing effect, but also provides more stable control through friction when the user forces to open the cover, reducing the risk of sliding or accidental pop-up.

[0043] Further, as a preferred embodiment of the present scheme but not limited, the outer edge of the silica gel cover 2 is provided with a downward extending extension 25, and the inner side wall of the extension 25 is provided with an arch part 251 extending towards the stainless steel box body 1, which is used to support the arc-shaped flange 11.

[0044] In this embodiment, the design of the arch part can effectively wrap and support the bottom of the arc-shaped flange, thereby forming a multi-layer contact sealing structure between the connecting groove and the arc-shaped flange, further preventing liquid or gas leakage, and also enhancing the bonding force between the cover and the box body to avoid loosening or falling off of the cover due to external force or vibration. The working principle is that the arch part closely fits the bottom profile of the arc-shaped flange through elastic deformation, providing additional support while increasing friction and sealing pressure, making the connection between the cover and the box body more stable and easy to operate.

[0045] Further, as a preferred embodiment of the present scheme but not limited, the arch part 251 is arched from the slot opening of the connecting groove 24, and gradually tilts outward from top to bottom to form a fitting surface 252.

[0046] In this embodiment, the inclined design of the fitting surface not only guides the arc-shaped flange to be more smoothly embedded in the connecting groove, reducing the resistance during assembly, but also closely fits the outer surface of the arc-shaped flange through elastic deformation after the cover is closed, thereby forming an additional sealing barrier to effectively prevent liquid or gas leakage. The arched part of the arch part provides initial support force through elastic deformation, and when the user holds the first and second anti-scald parts with both hands to take out the lunch box, the fitting surface will deform to fit the outer wall of the stainless steel box body, thereby driving the arch part to more stably support the arc-shaped flange, ensuring that the connection between the cover and the box body is more stable.

[0047] Further, as a preferred embodiment of the present scheme but not limited, the stainless steel box body 1 is made of 316L type stainless steel.

[0048] In this embodiment, the stainless steel body adopts 316L type stainless steel material, which not only has excellent corrosion resistance, high temperature resistance and food safety, but also can ensure that no arc and spark will be generated within the commonly used heating time range of 0~891 seconds during the microwave heating process, without affecting the heating effect of the food; the low magnetic permeability and stable structure of 316L stainless steel make it perform well in the microwave environment, thereby ensuring the safety of the heating process; in addition, its good thermal conductivity and uniform heat distribution characteristics can ensure uniform heating of the food, avoid the problem of local overheating or uneven heating, and improve the user experience.

[0049] Further, as a preferred embodiment of the present scheme but not limited, the inner side of the connecting groove 24 is provided with a clamping part 242 which is in interference fit with the inner side wall of the stainless steel body 1 from inside to outside, the rib 241 is correspondingly arranged on the clamping part 242, and the clamping part 242 is provided with an inwardly inclined arc edge 243 at the bottom edge, which cooperates with the arch part 251 to guide the direction of the slot opening of the connecting groove 24 to the direction of the stainless steel body 1.

[0050] In this embodiment, by arranging the clamping part which is in interference fit with the inner side wall of the stainless steel body from inside to outside in the inner side of the connecting groove, and correspondingly arranging the rib on the clamping part, and designing the inwardly inclined arc edge at the bottom edge of the clamping part to cooperate with the arch part to guide the slot opening of the connecting groove to the direction of the stainless steel body, the sealing performance and assembly stability of the meal box can be significantly improved; the design of the clamping part enhances the tight connection between the silicone cover and the stainless steel body through interference fit, and the existence of the rib further increases the local pressure and friction force, so that the cover is not easy to loosen or fall off during use; the inclined design of the arc edge can effectively guide the position alignment during assembly of the cover, reduce the installation resistance, and at the same time form a multi-layer sealing structure with the arch part to prevent liquid or gas leakage.

[0051] The working principle of the present embodiment is as follows:

[0052] The silicone cover stainless steel meal box of the present application is provided with downwardly extending first and second anti-scald parts on two opposite sides of the silicone cover body, which effectively reduces the heat transfer from the stainless steel body to the cover and the edge during the microwave heating process by using the heat insulation performance of the silicone material, thereby significantly reducing the risk of scalding when the user takes out the meal box; at the same time, the matching connection of the silicone cover body and the stainless steel body not only ensures the sealing performance, but also has the characteristics of lightness and durability, thereby improving the safety and convenience of the meal box during microwave heating.
