In another specific embodiment, as shown in fig. 5, the second bottom 21 may be provided with a second through hole 212b, so that the second bottom 21 is of a hollow structure, at least a portion of the outer bottom wall of the first bottom 11 is exposed through the second through hole 212b, and when the outer wall of the first bottom 11 is made of a magnetic conductive material (for example, a carbon-based material), the container can be used on a heating device needing magnetic conduction, such as an induction cooker, so as to increase the application range of the cooking device, and meanwhile, no additional magnetic conduction device is required to be added on the outer wall of the second bottom 21 of the container body, so that the container body is simpler in structure and lower in manufacturing cost. In addition, the second through hole 212b has a larger size, so that the exposed area of the outer wall of the first bottom 11 is larger, the contact area between the container body and a heating device needing magnetic conduction can be increased, the heating effect is good, and the use feeling is improved.

In the above embodiments, as shown in fig. 4, the second bottom 21 includes the first portion 212 and the second portion 213, and the second portion 213 is of a ring-shaped structure and is located at the outer periphery of the first portion 212. Along the height direction of the container body, the bottom wall of the first portion 212 is located at one side of the bottom wall of the second portion 213 close to the inner layer 1, that is, when the container body is placed on a horizontal table top, the second portion of the container body contacts the table top, and a preset distance is provided between the first portion and the table top, at this time, the through hole 212a of the second bottom 21 may be disposed in the first portion, so that the third protruding portion 112 of the first bottom 11 is exposed through the through hole 212a of the second bottom 21, and the preset distance between the first portion 212 and the table top can protect the third protruding portion 112 exposed through the through hole 212a of the first portion 212, so as to reduce the risk of abrasion of the third protruding portion 112. Meanwhile, when the container body is used on a cooker, the distance between the second part 213 and the cooker is larger than that between the first part 212 and the cooker, so that the first part 212 can be protected, the risk of damage to the third protruding part 112 exposed through the first part 212 in the using process of the cooking utensil is reduced, and the service life of the container body is prolonged.

Wherein the distance between the bottom wall of the first portion 212 and the bottom wall of the second portion 213 may be 0.5mm-5mm.

Specifically, as shown in fig. 4, a plurality of grooves 213a are formed in the annular second portion 213, and when the container body is placed on the table top, the grooves 213a can reduce the phenomenon that the container body and the table top slip and displace due to the vaporization of water drops and other factors, thereby improving the safety of the product. At least part of the grooves 213a are symmetrically distributed in the annular second portion 213, so that the risk of slipping between the container body and the table top can be reduced from all directions.

The foregoing is merely a specific implementation of the embodiment of the present application, but the scope of the embodiment of the present application is not limited thereto, and any changes or substitutions within the technical scope of the embodiment of the present application should be covered by the scope of the embodiment of the present application. Therefore, the protection scope of the embodiments of the present application shall be subject to the protection scope of the claims.
