By the way, the conventional Kimchi refrigerator storage container, because the circumferential wall is formed to be inclined in consideration of the flow of cold air in the cooling chamber, it does not use all the actual volume of the cooling chamber. Thereby, there is a problem that the volume of the cooling chamber provided to the user is reduced.

In order to solve this problem, the circumferential wall of the storage container may be formed to correspond to the inner wall surface of the cooling chamber, but in this case, the storage container and the inner wall surface of the cooling chamber may be in close contact with each other to secure a cold air flow space. As a result, a temperature difference occurs between a region where the storage container and the inner wall surface of the cooling chamber are in close contact with each other and a region where the storage wall is not in close contact with each other may not be able to normally store the storage of kimchi or the like contained in the storage container.

In particular, in the case of the direct-cooled kimchi refrigerator, there is a fear that the freezing phenomenon such as kimchi occurs in the inner circumference and bottom region (“C” and “D” of FIG. 6) of the storage container adjacent to the inner wall surface of the cooling chamber and deteriorated. There is a problem that is large.

Accordingly, an object of the present invention is to provide a storage container for a refrigerator capable of maximizing the internal volume of the cooling chamber and allowing the flow of cold air formed in the cooling chamber to be smoothly prevented from deterioration of the stored matter. .
