Description

Technical Field

[0001] The present application relates to the technical field of cooking utensils, and in particular to a container cover and a cooking container. Background Art

[0002] Cooking containers consist of a lid and a container. The lid prevents food from spilling, seals the container, and maintains heat during cooking. Existing lids are typically made of glass, allowing users to directly observe the cooking progress of the food and more accurately control the heat and cooking time. However, during the production process, lids often break or break, resulting in low yields and high production costs. Utility Model Content

[0003] In view of this, the present application provides a container cover and a cooking container to solve the technical problem in the prior art that the container cover is prone to edge cracking or overall rupture during processing.

[0004] The present application provides a container lid, which includes a body and at least one limiting portion, wherein the body and the limiting portion are made of glass; the limiting portion is connected to one side of the body along the thickness direction of the container lid, wherein along the thickness direction of the container lid, the thickness of the body is H1, the thickness of the limiting portion is H2, and H1 and H2 satisfy 0.8≤H1 / H2≤1.2.

[0005] In the embodiment of the present application, the main body is used to seal the opening of the container body, and the limiting portion is used to abut against the side wall of the opening of the container body so that the container lid can be smoothly covered on the opening of the container body, reducing the possibility of relative movement between the container lid and the container body, and improving the sealing between the container lid and the container body during cooking.

[0006] When the thickness of the main body and the limiting portion satisfies 0.8≤H1 / H2≤1.2, the thickness ratio between the two is close to 1:1, so that the thickness difference between the main body and the limiting portion is small, so as to reduce the possibility of the container lid bursting or overall fragmentation during the processing, thereby solving the problem of poor quality of the finished container lid, which is beneficial to reducing the scrap rate of the container lid, improving the yield of the container lid, and further reducing production costs and improving the quality of the finished product.

[0007] In a possible implementation manner, the thickness H1 of the main body satisfies 3mm≤H1≤5mm, and / or the thickness H2 of the limiting portion satisfies 3mm≤H2≤5mm.

[0008] In the embodiments of the present application, when the thickness of the body satisfies 3mm ≤ H1 ≤ 5mm, the container lid can be processed with high transparency and good heat transfer efficiency, thereby improving safety during cooking. When the thickness of the stopper satisfies 3mm ≤ H2 ≤ 5mm, the container lid can be easily placed on the opening of the container body while being easily accessible to the user. This improves user safety during cooking and reduces the production cost of the container lid.

[0009] In a possible embodiment, the surface area of the body is larger than the surface area of the limiting portion, so that an annular groove is provided between the body and the limiting portion, and the annular groove is used to cooperate with the side wall of the container body.

[0010] In the embodiment of the present application, when the container lid is attached to the container body, the annular groove of the container lid abuts against the sidewall of the container body opening, allowing the container lid to be smoothly attached to the container body opening. This reduces the possibility of relative movement between the container lid and the container body, and improves the sealing between the container lid and the container body during cooking. Furthermore, during the manufacturing process of the container lid, the annular groove can be formed simultaneously with the stopper, thereby simplifying the production process of the container lid and improving the production efficiency of the container lid.

[0011] In a possible embodiment, along the thickness direction of the container cover, the main body has a first mating surface for abutting against the side wall of the container body, and along the radial direction of the container cover, the width of the first mating surface is L1, and L1 satisfies 3.5mm≤L1≤4.5mm.

[0012] In the embodiment of the present application, a first mating surface is provided on the side of the container body facing the container body along the thickness direction of the container lid. The first mating surface is configured to abut against the top surface of the container body's side wall, thereby supporting the container lid on the container body and sealing the container body's opening. This seals the interior of the container body and facilitates rapid cooking of food. The first mating surface of the body and the top surface of the container body's side wall are in surface contact, which helps increase the contact area between the two, improves the stability of the container lid after it is attached to the container body, and enhances the sealing effect of the container lid on the container body.

[0013] In one possible embodiment, along the radial direction of the container lid, the limiting portion has a second mating surface for abutting against the side wall of the container body, and along the thickness direction of the container lid, the height of the second mating surface is L2, and L2 satisfies 2.5mm≤L2≤4.5mm; the first mating surface and the second mating surface form the annular groove.

[0014] In the embodiment of the present application, a second mating surface is provided on the outer side wall of the limiting portion along the radial direction of the container lid. The second mating surface is used to abut against the inner side surface of the side wall of the container body to limit the movement of the container lid relative to the container body in this direction, thereby improving the stability and reliability of the connection between the two. This reduces the possibility of displacement of the container lid under the action of steam during cooking, thereby improving the reliability of the container lid during cooking. The first mating surface and the second mating surface can also form the aforementioned annular groove, so that the container lid can abut against the side wall of the container body simultaneously through the first mating surface and the second mating surface, thereby further improving the stability and reliability of the connection between the two.

[0015] In a possible implementation, the first mating surface and the second mating surface are connected by an arc segment, a central angle of the arc segment is θ, and θ satisfies 0.5°≤θ≤1.5°.

[0016] In the embodiment of the present application, since the first mating surface extends radially of the container lid and the second mating surface extends along the thickness direction of the container lid, the first mating surface and the second mating surface are perpendicular to each other. This creates a risk of stress concentration at the connection between the first and second mating surfaces during the processing of the container lid. Therefore, by providing an arc segment at the connection between the first and second mating surfaces, the possibility of stress concentration at the connection between the two is reduced, thereby avoiding the risk of cracks and breakage of the container lid due to stress concentration, which is beneficial to improving the strength and service life of the container lid.

[0017] In a possible implementation, the container cover includes at least two limiting portions, and the surface areas of adjacent limiting portions gradually decrease in a direction away from the body.

[0018] In an embodiment of the present application, the container lid includes at least a first limiting portion (not marked in the figure) and a second limiting portion (not marked in the figure). Along the direction away from the main body, one side of the first limiting portion is connected to the main body, and the other side of the first limiting portion is connected to the second limiting portion. The surface area of the main body is larger than the surface area of the first limiting portion, and the surface area of the first limiting portion is larger than the surface area of the second limiting portion, so that an annular groove is formed between the first limiting portion and the main body, and a second annular groove is formed between the first limiting portion and the second limiting portion, so that the container lid can be suitable for container bodies with different opening sizes, expand the scope of application of the container lid, and thus help improve the versatility of the container lid.

[0019] In a possible implementation manner, the main body and the limiting portion are an integrally formed flat plate structure.

[0020] In the embodiments of the present application, both the main body and the retaining portion are flat plates, resulting in a larger contact area between them and facilitating a secure connection between the main body and the retaining portion. Furthermore, the flat surfaces of both facilitate processing, reducing the difficulty in manufacturing the container lid. Furthermore, the main body and the retaining portion can be integrally formed, which helps improve the stability and reliability of the connection between them, thereby providing the container lid with good integrity and enhancing its structural stability. Furthermore, the integral molding method can simplify the production process of the container lid and improve production efficiency.

[0021] In a possible implementation manner, the container cover is provided with at least one through hole penetrating along a thickness direction of the container cover.

[0022] In the embodiment of the present application, the through hole can be used as an exhaust hole of the container lid for installing an exhaust valve (not shown in the figure). During the cooking process, when the container lid is closed on the container body, the container lid can block the opening of the container body, and the exhaust valve can block the exhaust hole, so that the interior of the container body is in a sealed state, so as to generate positive pressure during the continuous heating of the container body, which is conducive to improving cooking efficiency; when the container body is continued to be heated so that the steam inside the container body is excessive and the pressure is too high, the exhaust valve can move upward relative to the container lid along the thickness direction of the container lid under the action of the steam, thereby opening the exhaust hole, and then allowing the interior of the container body to communicate with the external environment through the exhaust hole, so as to balance the internal and external pressure differences during the continuous heating of the container body, thereby improving cooking efficiency and safety during the cooking process.

[0023] The present application also provides a cooking container, comprising a container cover and a container body, wherein the container cover is any one of the container covers described above; wherein the container cover is fitted onto the container body.

[0024] In the embodiment of the present application, the first mating surface of the container lid can abut against the top surface of the side wall of the container body, and the second mating surface of the container lid can abut against the inner side surface of the side wall of the container body, so that the container lid can be smoothly covered on the opening of the container body, reducing the possibility of relative movement between the container lid and the container body during cooking, improving the sealing and safety of the cooking container during cooking, and being able to lock heat and moisture inside the container body to improve the cooking effect.

[0025] It should be understood that the foregoing general description and the following detailed description are merely illustrative and are not restrictive of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0044] It should be clear that the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0045] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0046] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0047] The embodiment of the present application provides a container cover for a cooking container, such as Figure 1 and Figure 3 As shown, the container lid 1 includes a body 11 and at least one stopper 12, which is connected to one side of the body 11 along the thickness direction of the container lid 1. The body 11 and the stopper 12 are both made of glass. Along the thickness direction of the container lid 1, the thickness of the body 11 is H1, and the thickness of the stopper 12 is H2, and H1 and H2 satisfy 0.8≤H1 / H2≤1.2.

[0048] In the embodiment of the present application, when the container lid 1 is placed on the container body 2, the stopper 12 is located on the side of the main body 11 facing the container body 2 along the thickness direction of the container lid 1. The main body 11 is used to seal the opening of the container body 2, and the stopper 12 is used to abut against the side wall of the opening of the container body 2, so that the container lid 1 can be smoothly placed on the opening of the container body 2, reducing the possibility of relative movement between the container lid 1 and the container body 2, and improving the sealing between the container lid 1 and the container body 2 during cooking.

[0049] During the manufacturing process of the container lid 1, the raw glass material undergoes various steps, including cutting, rough machining, fine machining, and tempering, to form the final product. The body 11 and the stopper 12 of the container lid 1 can be formed during the rough machining and fine machining processes, and the thickness ratio H1 / H2 between the body 11 and the stopper 12 can be, for example, 0.8, 0.82, 0.84, 0.86, 0.88, 0.9, 0.92, 0.94, 0.96, 0.98, 1, 1.03, 1.05, 1.07, 1.09, 1.1, 1.13, 1.15, 1.17, 1.19, or 1.2.

[0050] When the thickness ratio between the main body 11 and the limiting portion 12 is too small or too large (for example, H1 / H2 is less than 0.8 or H1 / H2 is greater than 1.2), the thickness difference between the main body 11 and the limiting portion 12 is relatively large, which may easily lead to uneven stress distribution on the container cover 1 during the processing of the container cover 1, thereby posing the possibility of edge bursting or overall fragmentation, thereby resulting in a low yield of the container cover 1 and a high production cost.

[0051] Therefore, when the thickness of the main body 11 and the limiting portion 12 satisfies 0.8≤H1 / H2≤1.2, the thickness ratio between the two is close to 1:1, so that the thickness difference between the main body 11 and the limiting portion 12 is small, so as to reduce the possibility of the container lid 1 bursting or overall fragmentation during the processing, thereby solving the problem of poor quality of the finished container lid 1, which is beneficial to reducing the scrap rate of the container lid 1, improving the finished product rate of the container lid 1, and further reducing production costs and improving the quality of the finished product.

[0052] It should be noted that the container lid 1 may include a lid body and a handle mounted on the lid body. In some embodiments, the lid body may only include the body 11 and the stopper 12 described above. In other embodiments, the lid body may include other structures in addition to the body 11 and the stopper 12. For example, the stopper 12 may be sleeved with a seal, or the outer peripheral wall of the body 11 may be wrapped with a metal edging. As long as the container lid 1 includes a body 11 and a stopper 12 made of glass, it is within the scope of protection of this application.

[0053] In a specific embodiment, Figure 5 As shown, the thickness H1 of the body 11 satisfies 3 mm ≤ H1 ≤ 5 mm.

[0054] In the embodiment of the present application, the thickness H1 of the main body 11 can be 3mm, 3.1mm, 3.3mm, 3.5mm, 3.7mm, 3.9mm, 4.1mm, 4.3mm, 4.5mm, 4.7mm, 4.9mm, 5mm, etc.

[0055] When the thickness of the body 11 is too small (for example, H1 is less than 3 mm), the processing difficulty of the container cover 1 is too great and the production cost is too high.

[0056] When the thickness of the main body 11 is too large (for example, H1 is greater than 5 mm), the transparency of the container lid 1 is too low, making it impossible for the user to clearly observe the cooking conditions inside the container body 2 through the container lid 1, resulting in the risk of food being cooked for too long. In addition, during the cooking process, the overly thick main body 11 cannot transfer heat in time, resulting in an excessively large pressure difference between the inner and outer walls of the container lid 1, thereby causing the container lid 1 to be at risk of bursting.

[0057] Therefore, when the thickness of the body 11 satisfies 3mm≤H1≤5mm, it can reduce the processing difficulty and production cost of the container cover 1 while having high transparency and good heat transfer efficiency to improve safety during the cooking process.

[0058] In a specific embodiment, Figure 5 As shown, the thickness H2 of the limiting portion 12 satisfies 3mm≤H2≤5mm.

[0059] In the embodiment of the present application, the thickness H2 of the limiting portion 12 can be 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm, 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, etc.

[0060] When the thickness of the limiting portion 12 is too small (for example, H2 is less than 3 mm), after the container lid 1 is closed on the opening of the container body 2, the area where the limiting portion 12 and the opening of the container body 2 abut against each other is too small, resulting in the possibility of relative movement between the container lid 1 and the container body 2 during the cooking process, thereby causing a risk of separation between the two.

[0061] When the thickness of the limiting portion 12 is too large (for example, H2 is greater than 5 mm), the distance that the limiting portion 12 extends into the interior of the container body 2 is too large, which is not conducive to the user to take and place the container cover 1. At the same time, the limiting portion 12 with an excessive thickness also requires excessive consumption of production materials, resulting in excessively high production costs for the container cover 1.

[0062] Therefore, when the thickness of the limiting portion 12 satisfies 3mm≤H2≤5mm, it can facilitate the user to take and place the container cover 1, and at the same time, the container cover 1 can be stably covered on the opening of the container body 2, which is beneficial to improving the safety of the user during cooking and reducing the production cost of the container cover 1.

[0063] In a specific embodiment, Figure 3 、 Figure 4 and Figure 5 As shown, the surface area of the main body 11 is larger than the surface area of the limiting portion 12 , so that an annular groove 13 is formed between the main body 11 and the limiting portion 12 , and the annular groove 13 is used to cooperate with the side wall of the container body 2 .

[0064] In the embodiment of the present application, the limiting portion 12 is connected to the side of the main body 11 facing the container body 2 along the direction away from the main body 11. When the surface area of the main body 11 is larger than the surface area of the limiting portion 12, an annular groove 13 can be formed between the main body 11 and the limiting portion 12.

[0065] When the container lid 1 is attached to the container body 2, the annular groove 13 of the container lid 1 abuts against the sidewall of the opening of the container body 2, allowing the container lid 1 to be smoothly attached to the opening of the container body 2. This reduces the possibility of relative movement between the container lid 1 and the container body 2 and improves the sealing between the container lid 1 and the container body 2 during cooking. Furthermore, during the manufacturing process of the container lid 1, the annular groove 13 can be formed simultaneously with the stopper 12, thereby simplifying the production process of the container lid 1 and improving the production efficiency of the container lid 1.

[0066] In a specific embodiment, Figure 2 and Figure 5 As shown, along the thickness direction of the container cover 1, the main body 11 has a first mating surface 111 for abutting against the side wall of the container body 2, and along the radial direction of the container cover 1, the width of the first mating surface 111 is L1, and L1 satisfies 3.5mm≤L1≤4.5mm.

[0067] In the embodiment of the present application, a first mating surface 111 is provided on the side of the main body 11 facing the container body 2 along the thickness direction of the container lid 1. The first mating surface 111 is used to abut against the top surface of the side wall of the container body 2 so that the container lid 1 can be supported on the container body 2 and seal the opening of the container body 2, so that the interior of the container body 2 is in a sealed state, which is convenient for quickly cooking food.

[0068] Among them, the first mating surface 111 of the main body 11 and the top surface of the side wall of the container body 2 are in surface contact, which is beneficial to increase the contact area between the two, improve the stability of the container cover 1 after it is covered on the container body 2, and improve the sealing effect of the container cover 1 on the container body 2.

[0069] Specifically, along the radial direction of the container cover 1, the width of the first mating surface 111 is L1, and L1 can specifically be 3.5mm, 3.6mm, 3.7mm, 3.8mm, 3.9mm, 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, etc.

[0070] When the width of the first mating surface 111 is too small (for example, L1 is less than 3.5 mm), the contact area between the main body 11 and the side wall of the container body 2 is too small, resulting in poor sealing effect of the container lid 1 on the opening of the container body 2. There is a risk of steam leaking from the container body 2 during cooking, causing burns to the user.

[0071] When the width of the first mating surface 111 is too large (for example, L1 is greater than 4.5 mm), the distance between the limiting portion 12 and the side wall of the container body 2 is too large, resulting in the possibility of relative movement between the container cover 1 and the container body 2 during the cooking process, thereby causing a risk of separation between the two. At the same time, the first mating surface 111 with an excessively large width may also easily cause the container cover 1 to burst or break as a whole during processing.

[0072] Therefore, when the width of the first mating surface 111 satisfies 3.5 mm ≤ L1 ≤ 4.5 mm, the container cover 1 can be stably covered on the opening of the container body 2 , which is beneficial to improving the sealing of the cooking container and increasing the yield of the container cover 1 during the production process.

[0073] In a specific embodiment, Figure 2 and Figure 5 As shown, along the radial direction of the container cover 1, the limiting portion 12 has a second mating surface 121 for abutting against the side wall of the container body 2, and along the thickness direction of the container cover 1, the height of the second mating surface 121 is L2, and L2 satisfies 2.5mm≤L2≤4.5mm.

[0074] In the embodiment of the present application, a second mating surface 121 is provided on the outer side wall of the limiting portion 12 along the radial direction of the container lid 1. The second mating surface 121 is used to abut against the inner side surface of the side wall of the container body 2 to limit the movement of the container lid 1 relative to the container body 2 in this direction, thereby improving the stability and reliability of the connection between the two, thereby reducing the possibility of displacement of the container lid 1 under the action of steam during the cooking process, and improving the reliability of the container lid 1 during the cooking process.

[0075] Specifically, along the thickness direction of the container cover 1, the height of the second mating surface 121 is L2, and L2 can specifically be 2.5mm, 2.7mm, 2.9mm, 3.1mm, 3.3mm, 3.5mm, 3.7mm, 3.9mm, 4.1mm, 4.3mm, 4.5mm, etc.

[0076] When the height of the second mating surface 121 is too small (for example, L2 is less than 2.5 mm), the contact area between the second mating surface 121 and the inner side surface of the side wall of the container body 2 is too small, resulting in the possibility of relative movement between the container cover 1 and the container body 2 during the cooking process, thereby causing a risk of separation between the two.

[0077] When the height of the second mating surface 121 is too large (for example, L2 is greater than 4.5 mm), the distance that the limiting portion 12 extends into the interior of the container body 2 is too large, making it inconvenient for the user to take or place the container cover 1 .

[0078] Therefore, when the height of the second mating surface 121 satisfies 2.5mm≤L2≤4.5mm, it can facilitate the user to take and place the container cover 1, and can also make the container cover 1 stably cover the opening of the container body 2, which is beneficial to improving the safety of the user when cooking.

[0079] In a possible embodiment, the first mating surface 111 and the second mating surface 121 can form the above-mentioned annular groove 13, so that the container cover 1 can simultaneously abut against the side wall of the container body 2 through the first mating surface 111 and the second mating surface 121, thereby further improving the stability and reliability of the connection between the two.

[0080] In a specific embodiment, Figure 2 and Figure 5 As shown, the first mating surface 111 and the second mating surface 121 are connected by an arc segment 14 , the central angle of the arc segment 14 is θ, and θ satisfies 0.5°≤θ≤1.5°.

[0081] In the embodiment of the present application, since the first mating surface 111 extends radially along the container lid 1 and the second mating surface 121 extends along the thickness direction of the container lid 1, the first mating surface 111 and the second mating surface 121 are perpendicular to each other. As a result, during the processing of the container lid 1, there is a risk of stress concentration at the connection between the first mating surface 111 and the second mating surface 121. Therefore, in this embodiment, an arc segment 14 is provided at the connection between the first mating surface 111 and the second mating surface 121 to reduce the possibility of stress concentration at the connection between the two, thereby avoiding the risk of cracks and breakage of the container lid 1 due to stress concentration, which is beneficial to improving the strength and service life of the container lid 1.

[0082] Specifically, the central angle θ of the arc segment 14 can be 0.5°, 0.6°, 0.8°, 0.9°, 1°, 1.1°, 1.2°, 1.3°, 1.4°, 1.5°, etc. When the central angle of the arc segment 14 satisfies 0.5°≤θ≤1.5°, the arc segment 14 can effectively reduce stress concentration at the connection between the first mating surface 111 and the second mating surface 121, and can also improve the aesthetics of the container lid 1.

[0083] In one possible embodiment, during the processing of the container cover 1, each outer surface of the container cover 1 can be polished, and arc segments are provided at the connection points of each outer surface of the container cover 1, which is beneficial to reduce the possibility of scratching the user's hands, improve the user's safety during use, and improve the aesthetics of the container cover 1.

[0084] In a specific embodiment, the container cover 1 includes at least two limiting portions 12 , and the surface areas of adjacent limiting portions 12 gradually decrease in a direction away from the body 11 .

[0085] In the embodiment of the present application, the container lid 1 includes at least a first limiting portion (not marked in the figure) and a second limiting portion (not marked in the figure). Along the direction away from the main body 11, one side of the first limiting portion is connected to the main body 11, and the other side of the first limiting portion is connected to the second limiting portion, and the surface area of the main body 11 is larger than the surface area of the first limiting portion, and the surface area of the first limiting portion is larger than the surface area of the second limiting portion, so that an annular groove 13 is formed between the first limiting portion and the main body 11, and a second annular groove 13 is formed between the first limiting portion and the second limiting portion, so that the container lid 1 can be suitable for container bodies 2 with different opening sizes, expanding the scope of application of the container lid 1, and thus helping to improve the versatility of the container lid 1.

[0086] In a specific embodiment, Figure 3 and Figure 5 As shown, the main body 11 and the limiting portion 12 are an integrally formed flat plate structure.

[0087] In the embodiment of the present application, both the main body 11 and the retaining portion 12 are flat-plate structures, which increases the contact area between the two and facilitates the fixed connection between the main body 11 and the retaining portion 12. The flat surfaces of the two facilitate processing, which can reduce the difficulty in the production and processing of the container lid 1. In particular, the main body 11 and the retaining portion 12 can be integrally formed, which helps to improve the stability and reliability of the connection between the two, thereby giving the container lid 1 good integrity and improving the structural stability of the container lid 1. At the same time, the integral molding method can also simplify the production process of the container lid 1 and improve production efficiency.

[0088] In a specific embodiment, Figure 1 and Figure 4 As shown, the container cover 1 is provided with at least one through hole 15 penetrating along the thickness direction of the container cover 1 .

[0089] In the embodiment of the present application, the through hole 15 can be used as an exhaust hole of the container lid 1 for installing an exhaust valve (not shown in the figure). During the cooking process, when the container lid 1 is closed on the container body 2, the container lid 1 can block the opening of the container body 2, and the exhaust valve can block the exhaust hole, so that the interior of the container body 2 is in a sealed state, so as to generate positive pressure during the continuous heating of the container body 2, which is conducive to improving cooking efficiency; when the container body 2 is continued to be heated so that the steam inside the container body 2 is too much and the pressure is too high, the exhaust valve can move upward relative to the container lid 1 along the thickness direction of the container lid 1 under the action of the steam, thereby opening the exhaust hole, and then allowing the interior of the container body 2 to communicate with the external environment through the exhaust hole, so as to balance the internal and external pressure differences during the continuous heating of the container body 2, thereby improving cooking efficiency while improving safety during the cooking process.

[0090] The embodiment of the present application also provides a cooking container, such as Figure 1As shown, the cooking container includes a container cover 1 and a container body 2 . The container cover 1 is the container cover 1 described above, and the container cover 1 covers the opening of the container body 2 .

[0091] In the embodiment of the present application, the first mating surface 111 of the container lid 1 can abut against the top surface of the side wall of the container body 2, and the second mating surface 121 of the container lid 1 can abut against the inner side surface of the side wall of the container body 2, so that the container lid 1 can be stably covered on the opening of the container body 2, reducing the possibility of relative movement between the container lid 1 and the container body 2 during the cooking process, improving the sealing and safety of the cooking container during cooking, and being able to lock heat and moisture inside the container body 2 to improve the cooking effect.

[0092] Furthermore, due to the high transparency of the container lid 1, the user can easily spot any food residue or splashes on the surface of the container lid 1, making it easier to handle and clean any stains, thereby maintaining the aesthetics of the container lid 1. Furthermore, the relatively smooth surface of the container lid 1 allows the user to easily clean any food residue or splashes from the surface of the container lid 1 without extensive soaking or vigorous scrubbing, thereby improving cleaning efficiency and enhancing the user experience. Furthermore, during the cooking process, the user can directly monitor the cooking status within the container body 2 through the container lid 1, eliminating the need to interrupt cooking. This facilitates user monitoring of food and allows for more precise control of the degree of cooking.

[0093] In addition, the container lid 1 can evenly distribute heat on the surface of the limiting portion 12 facing the interior of the container body 2. During the cooking process, when the container lid 1 is closed on the container body 2, the container lid 1 can retain heat inside the container body 2, so that a thermally uniform cooking environment can be formed inside the cooking container, ensuring that all parts of the food are cooked at the same speed, which is conducive to improving cooking efficiency.

[0094] It should be noted that the cooking container can be any kitchen appliance commonly used in the art, such as a steamer, hot pot, frying pan, boiling pot, multi-function electric hot pot, etc. The embodiment of the present application does not limit the specific type of the cooking container.

[0095] The above describes in detail the structure, features and effects of the present application based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present application, but the present application does not limit the scope of implementation to what is shown in the drawings. Any changes made in accordance with the concept of the present application, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present application.
