To provide a sealed container assuring its sealing performance.

The sealed container includes a container body having a container box body and a container lid body which can be fit into each other with an edge formed around the container body wherein the container box body has a box side at the edge and the container lid body has a lid side at the edge; a first engaging frame extending from the container body, and slid and fit into the edge by a groove corresponding to a half perimeter configuration smaller than the edge; a second engaging frame extending from the first engaging frame, and slid and fit into the edge by the groove corresponding to the half perimeter configuration smaller than the edge. The invention assures that the sealing configuration between the container body and the container lid body is not broken due to an external force by closely engaging the container body and the container lid body with the first engaging frame and the second engaging frame. By this, an improved effect on sealing reliability can be obtained.
