ABSTRACT:
A protective casing for removably retaining an environment-sensitive object such as a recording tape cartridge or a tape cassette and protecting such object from contamination as by dirt, dust, magnetic radiation, humidity, and temperature. The illustrated casing comprises rectangularly shaped upper and lower case sections which are hingedly connected together along one edge and maintained in that relationship by means of an elongated resilient wire torsion spring. The spring and portions of the case section edges combine to form the hinge for the casing. The case sections form a "clam-shell" construction, with the spring also serving to continuously bias the sections to a closed position against one another. The case may be manually opened and held open against the biasing force of the spring which will automatically reclose the casing as soon as it is released. The interior cavity of the casing is substantially sealed from the external atmosphere by means of a seal which extends along the periphery of one of the case sections. A humidity absorbing device and shield against magnetic radiation may also be provided in the casing. The humidity absorbing device is in a unique arrangement compatible with the limiting requirements regarding space, absorbing capacity, and absence of contamination. In this way, a tape cartridge or other environment-sensitive object retained within the casing is essentially sealed from the external atmosphere and protected from degrading environments.
