Claims (10)

1. A food container, characterized in that it comprises:

an outer container;

the cover body is covered on the outer container and matched with the outer container to form an accommodating space;

the first inner container is arranged in the accommodating space and is used for accommodating a first food material;

a second inner container stacked above the first inner container and used for containing a second food material.

2. The food container according to claim 1, wherein a first annular platform is provided on the side wall of the outer container, the first annular platform having a height such that when the first food material in the first inner container is poured into the outer container and the second inner container is replaced into the outer container, the second inner container is supported by the first annular platform and spaced a distance from the first food material poured into the outer container.

3. A food container as claimed in claim 2, wherein the open end of the lid is provided with at least two catches, and the open end of the outer container is provided with a first annular flange extending outwardly of the outer container, the catches being engageable with the first annular flange to retain the outer container and lid relatively fixed.

4. The food container as claimed in claim 3, wherein the second inner container is arranged to project relative to the open end of the outer container when the bottom of the second inner container is supported on the open end of the first inner container, such that the catch of the lid placed on the second inner container is located above the engagement region of the first annular flange, thereby placing the catch and the first annular flange in a disengaged state, and wherein the catch is located below the engagement region of the first annular flange when the second inner container is supported on the first annular platform, thereby enabling the catch and the first annular flange to engage with each other.

5. Food container as claimed in claim 4, characterized in that the side wall of the lid body is provided with a second annular platform which, when the second inner container is replaced in the outer container, rests on the first annular flange, the distance of the second annular platform with respect to the open end of the lid body being such that, when the second annular platform rests on the first annular flange, the catch is located below the first annular flange, thereby achieving the snap-fit.

6. The food container according to claim 1, wherein the second inner container is protrudingly provided with respect to the open end of the outer container to allow a first gripping mechanism to be clasped to an outer side of the second inner container and to take out the second inner container from the outer container, and the open end of the second inner container is provided with a second annular flange extending to an outer side of the second inner container, wherein the second annular flange is overlapped on the first gripping mechanism when the first gripping mechanism is clasped to an outer side of the second inner container.

7. The food container of claim 1 wherein the open end of the first inner container is further covered with a sealing film for sealing the first inner container to allow a second gripping mechanism to be attached to the sealing film and remove the first inner container from the outer container.

8. The food container of claim 7, wherein the open end of the first inner container is provided with a third annular flange extending outwardly of the first inner container, the sealing membrane being secured in abutment with the third annular flange.

9. The food container of claim 1, wherein the bottom portion of the second inner container is supported on the open end of the first inner container, and a fourth annular flange is protruded from a side of the bottom portion of the second inner container away from the open end of the second inner container and is fitted around the outer periphery of the open end of the first inner container.

10. The food container according to claim 1, wherein the first inner container is supported on a bottom portion of the outer container, a positioning boss is provided on the bottom portion of the outer container so as to protrude toward the open end side of the outer container, a positioning groove is correspondingly provided on the bottom portion of the first inner container so as to be away from the open end side of the first inner container, and the positioning boss and the positioning groove are fitted to each other.
