To provide a container for fermented soybeans enabling the opening/closing of a container body and a lid body, and the separation of the container body from the lid body to be easily performed.

A container for fermented soybeans comprises a container body and a lid body. The container body is configured by forming a flange part which is extended in a collar-shaped manner at an upper end peripheral edge of a filling part, forming a division flange part which is divided by a division slit at a front flange part of the flange part and forming a hinge part which opens/closes in a vertical direction at a rear flange part. The lid body is formed in a square shape and in a size for covering the filling part of the container body and the upper surface of the whole flange part, and it is configured by forming a separation slit breakable at the rear flange part. By spot welding both corner parts of the division flange part of the container body and the front flange part of the lid body, the container body and the lid body are spot welded and sealed. By breaking the division slit of the container body, the opening/closing of the container body and the lid body becomes easy, and by breaking the separation slit of the lid body, the separation of the container body from the lid body becomes easy.
