Claim:
A closed container comprising: a lid having a flat plate shape and having at least one engaged portion provided in said flat plate shape; a container body having an interior space in which an object can be stored, an opening in a surface of the container body, the opening allowing communication between said interior space and an external space and is to be closed by one side of said flat plate shape of said lid, a flange portion that extends from the periphery of said opening parallel to the surface in which the opening is formed and defines a receiving recess in which said lid is received in a state in which said opening is closed by said lid, and at least one insertion hole that passes from an outer surface of said flange portion to said receiving recess and is provided at a position aligned with said at least one engaged portion in said receiving recess in a state in which said lid is received in said receiving recess; and a latch mechanism having at least one latch main body mounted on the container body and movable along an axis parallel to said surface on which the opening is formed and extends in the direction of said axis, at least one link portion that is provided at the outer surface of said flange portion and projects from said at least one latch main body in a direction different from the direction along said axis, and at least one engagement portion disposed at an end of said at least one link portion, wherein said at least one engagement portion reaches said receiving recess through said at least one insertion hole, said at least one engagement portion engages with said at least one engaged portion of said lid disposed in said receiving recess, engagement of said at least one engagement portion with said at least one engaged portion and release of engagement thereof are achieved by movement of said at least one latch main body along said axis, said at least one engaged portion has an L-shape comprising a first straight portion extending along a direction in which an outer circumferential surface of said flat plate shape extends and a second straight portion having an open end on one surface of said flat plate shape and extending in a thickness direction of said lid, said at least one engagement portion can engage with an inner wall defining the first straight portion of said L-shape, and the engaged state is released by movement of said at least one engagement portion to said second straight portion with movement of said at least one latch main body along said axis, and said inner wall is located on the side closer to a rear surface of said lid opposed to said opening, the distance between said inner wall and said rear surface being closest at a joining portion of said first straight portion with said second straight portion, and said distance between said inner wall and said rear surface increasing with an increase in the distance from said joining portion.
