ABSTRACT:
A protective canister for computer discs comprises a hollow tube and a pair of end caps for closing the tube and fixing a central post therein. A stack of alternate computer discs and spacers having aligned central apertures is loaded onto the center post and clamped in the canister by way of a pair of platforms carried by the end caps about the central post. The elements of the canister are preferably constructed from hydrocarbon-based polymers and, after loading, the canister is sealed in shrink film so that the discs are protected in an environment which is free of particulate matter.
