This utility model discloses a sealed food storage container, including a container body, a lid that fits with the container body, and a flexible sealing ring. The lid is a downward-opening cover structure. An annular groove with the opening facing downwards is provided around the outer edge of the container body's opening. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring protrudes outside the annular groove, sealing with the inner wall of the lid when the lid is placed on the container body's opening. This sealed food storage container achieves a seal while preventing the sealing ring from contacting the food inside the container, thus effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container. Therefore, frequent disassembly and cleaning of the sealing ring is unnecessary, reducing the user's maintenance burden. Furthermore, since the edge of the lid and the sealing ring are not located within the internal space of the container body, the container body can achieve a larger effective volume with the same external dimensions, fully accommodating food and improving its internal space utilization.
