[0038] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present application and implement it, but the embodiments are not intended to limit the present application.

[0039] This application mentions a semi-circular lunch box, such as Figure 1 and Figure 2 As shown, it includes: an outer lunch box 110, an inner lunch box 120, and an exhaust assembly 130;

[0040] Among them, reference Figure 2 , Figure 4 and Figure 5 The inner lunch box 120 is placed in the outer lunch box 110, and the outer lunch box 110 is used to heat the inner lunch box 120; the outer lunch box 110 includes: an outer lunch box body 111 and an outer lunch box cover 112 adapted to the outer lunch box body 111; a heating area for placing the inner lunch box 120 is arranged in the outer lunch box 110, and the heating area is in contact with the bottom of the inner lunch box 120; the inner lunch box 120 includes an inner lunch box body 121 for placing food when in use, and a sealing film 122 for temporarily sealing the top opening of the inner lunch box 120 and can be torn off;

[0041] refer to Figure 5 The inner lunch box 120 is designed to house the outer lunch box 110, so that the outer lunch box cover 112 is not directly heated. For example, the inner lunch box 120 and the sealing film 122 are both disposable products. The sealing film 122 covers the top of the inner lunch box body 121 and ensures that the sealing film 122 fits tightly to the edge of the lunch box to seal the food and prevent steam and heat from escaping.

[0042] refer to Figure 3 and Figure 5 The sealing film 122 is provided with an exhaust hole 123, the outer lunch box cover 112 is provided with a groove, and the exhaust component 130 is detachably embedded in the groove and connected to the exhaust hole 123, so as to discharge the hot air generated by heating the food out of the semi-circulation lunch box.

[0043] refer to Figure 2 When the inner lunch box 120 needs to be heated, the inner lunch box 120 is placed in the outer lunch box body 111 and covered with the outer lunch box cover 112. At this time, the exhaust component 130 embedded in the groove of the outer lunch box cover 112 is inserted into the exhaust hole 123 at the corresponding position on the sealing film 122. The hot air generated by heating the food will be discharged outside the semi-circulation lunch box along the exhaust component 130. The outer lunch box cover 112 may not contact the sealing film 122, thereby preventing the outer lunch box cover 112 from being directly heated, and the hot air discharged from the exhaust hole 123 on the sealing film 122 is discharged through the exhaust channel 131, thereby preventing the hot air from heating the outer lunch box cover 112.

[0044] In addition, refer to Figure 1 The exhaust assembly 130 and the outer lunch box cover 112 are detachable for easy cleaning. When the exhaust assembly 130 changes color or deforms due to heat, it is only necessary to replace the exhaust assembly 130 with the corresponding specifications to ensure the hygiene of the lunch box. The above design provides more flexibility and convenience for the semi-circular lunch box, which can meet the needs of different users and is also conducive to reducing the use cost and resource waste of the lunch box.

[0045] refer to Figure 1 and Figure 6 In a feasible embodiment, the exhaust component 130 is an exhaust channel 131, and the air inlet end of the exhaust channel 131 is provided with an elastic spherical capsule cavity 132 connected to the exhaust hole 123 on the sealing film 122, and the bottom of the elastic spherical capsule cavity 132 is provided with a capsule cavity exhaust port corresponding to the exhaust hole 123 on the sealing film 122 when in use, and air outlets 134 are opened on both sides of the exhaust channel 131.

[0046] For example, the elastic spherical capsule 132 is a capsule of a spherical structure, which has certain elastic properties. It can be made of food-grade rubber, food-grade silicone or food-grade elastic plastic. The elastic spherical capsule 132 can be deformed when subjected to external pressure or extrusion, and can return to its original shape after the external force is removed.

[0047] In a feasible implementation, a connection port is provided at the bottom of the groove on the outer lunch box cover 112 , and the elastic spherical capsule 132 on the exhaust channel 131 passes through the connection port and is connected to the exhaust hole 123 on the sealing film 122 .

[0048] When the outer lunch box cover 112 is tightly closed, the elastic spherical cavity 132 can pass through the connecting port and enter the exhaust hole 123 on the sealing film 122 by being squeezed. After entering the exhaust hole 123, the elastic spherical cavity 132 returns to its original shape, so that the elastic spherical cavity 132 and the exhaust hole 123 are tightly fitted. When heating food, the elastic spherical cavity 132 presses the sealing film 122 and connects the cavity exhaust port corresponding to the exhaust hole 123 on the sealing film 122. In this way, when hot air is discharged, it can only be discharged along the preset path of the exhaust hole 123, the elastic spherical cavity 132 and the exhaust channel 131. When the hot air enters the exhaust channel 131 from the elastic spherical cavity 132, it is discharged from the air outlets 134 on both sides of the exhaust channel 131.

[0049] In a feasible embodiment, the sac cavity exhaust port is a one-way exhaust hole 123. When the inner lunch box 120 is heated, the food will release hot air and steam. Excessive hot air and steam may cause the pressure to rise. The pressure inside the container will gradually increase, which may cause the container to deform or explode, thereby increasing the safety risk during use. The one-way exhaust hole 123 can effectively remove excess hot air and steam and keep the pressure inside the container stable. When there is reverse flow of gas outside, the one-way flow of gas is achieved through the one-way exhaust hole 123 to prevent the gas from flowing back, effectively release the pressure inside the inner lunch box 120, and reduce the possibility of accidents caused by excessive pressure in the inner lunch box 120.

[0050] In a feasible implementation manner, the one-way exhaust hole 123 includes: a membrane type one-way exhaust hole 123 and a permeation type one-way exhaust hole 123 .

[0051] It can be understood that the diaphragm-type one-way exhaust hole 123 realizes one-way gas flow through a film or the like. When the gas applies pressure from one side, the film diaphragm will open to allow the gas to flow out; and under the reverse action, it will close, thereby preventing the gas from flowing back.

[0052] It is understandable that the permeable one-way exhaust hole 123 utilizes the characteristics of the material to allow only one-way gas permeation under certain conditions to achieve the exhaust effect. For example, the material may be a porous polymer film (such as food-grade polypropylene (PP) material or food-grade polyethylene (PE) material) or a polyester film, which usually has a tiny pore structure to achieve one-way gas permeability.

[0053] In a feasible embodiment, card interfaces 135 are provided on both sides of the bottom of the groove on the outer lunch box cover 112, and buckles 136 corresponding to the card interfaces 135 are provided on the exhaust channel 131. The card interfaces 135 and buckles 136 on the outer lunch box cover 112 are used to fix the cover and the exhaust channel 131. When the elastic spherical capsule 132 is squeezed into the exhaust hole 123 on the sealing film 122 or the exhaust port is pulled out by external force, it is only necessary to open and close the cover between the outer lunch box cover 112 and the outer lunch box body 111. When the exhaust assembly 130 needs to be cleaned or replaced, it is only necessary to insert the buckle 136 into the card interface 135, which can be completed quickly and easily without additional tools or force.

[0054] refer to Figure 5 In a feasible implementation, there are multiple inner lunch box bodies 121, and the multiple inner lunch box bodies 121 are provided with a matching number of sealing films 122, and the sealing films 122 are all provided with exhaust holes 123, and the exhaust holes 123 are respectively connected to the exhaust components 130.

[0055] It is understandable that by arranging a plurality of inner lunch box bodies 121 in the semi-circulation lunch box, different types of food can be conveniently separated to form different functional areas. Each inner lunch box body 121 is equipped with a sealing film 122, and the exhaust holes 123 opened on each sealing film 122 can heat the food in different areas as desired.

[0056] In a feasible implementation manner, the semi-circular lunch box further includes: a handle assembly 150 , and the handle assembly 150 is disposed on the outer lunch box 110 .

[0057] For example, the handle assembly 150 can be a handle, which makes the lunch box easier to carry. In addition, the handle can help users avoid direct contact with hot surfaces and reduce the risk of burns. The handle of the lunch box can provide a convenient, stable and safe way to carry, help maintain the hygiene and safety of food, and improve the user experience.

[0058] refer to Figure 7 In a feasible implementation, the semi-circulation lunch box also includes an auxiliary lunch box 140, wherein the outer lunch box cover 112 is provided with an embedding groove adapted to the size of the auxiliary lunch box 140, and the auxiliary lunch box 140 is detachably embedded in the auxiliary lunch box 140 to increase the storage space for the semi-circulation lunch box.

[0059] Exemplarily, the auxiliary lunch box 140 can be divided into a plurality of small areas for placing different types of food, such as main dishes, side dishes, fruits, etc., so that the food will not be mixed. Similarly, the auxiliary lunch box 140 can also accommodate eating utensils such as knives, forks, and spoons.
