An improved hard disk container of the type having a container body with U-shaped disk receiving grooves therein and covers over upper and end openings in opposite ends and over a lower opening. Continuous upper and end protrusions are integrally mounted adjacent the upper opening and on the ends adjacent the end openings, and a continuous lower protrusion is integrally mounted around the lower opening. The lower face of the upper cover has continuous upper and end grooves therein in which the continuous upper and end protrusions are engaged. A continuous sealing upper projection is integrally provided on the wall of the continuous upper and end grooves and the upper and end protrusions have a continuous sealing recess therein in which the continuous upper projection is resiliently sealingly engaged. The lower cover has a continuous lower groove around the upper surface in which the continuous lower protrusion is engaged, and a continuous sealing lower projection is integrally provided on the wall of the lower groove, the continuous lower protrusion having a continuous sealing recess therein in which the continuous lower sealing projection is resiliently sealingly engaged. Pairs of brackets are detachably mounted on the upper cover and project into the disk receiving grooves for resiliently engaging hard disks in the container body so as to position the hard disks in the disk receiving grooves. Humidity absorbing material is provided in the container body for absorbing humidity.
