A food container includes a body and a lid. The body has a first containing space which has a first opening and a first rim on the edge of the first opening. The lid has a second rim coupled to the first rim. The first rim is extended to form a first horizontal section which is extended to form a first bent section. The first bent section further is extended to form a first latch section. The second rim is extended to form a second horizontal section, a second bent section and a second latch section. The first and second latch sections have respectively a first and second positioning portion. When the lid covers the body, the second horizontal section presses the second bent section in contact with the first bent section so that the first and second positioning portions are engaged, thereby to enhance coupling strength and sealing tightness.
