摘要
A protective or purge enclosure provides a positive atmosphere around an operating device such as a hand-held computer or calculator contained therein. The protective enclosure has sufficient flexibility, even though providing a positive, sealed atmosphere, to enable the user to operate the functional features of the device sealed within the enclosure, and the material forming the device is sufficiently transparent to enable the user to view the functional features of the device for operation. A visible indicator provided on the enclosure enables the user to determine if the enclosure is maintaining the positive atmosphere sealed therein.
