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.

A protective canister for protecting a plurality of computer discs of the type having a pair of opposite main surfaces, a central aperture and a pair of bevel surfaces each extending from a respective main surface into the central aperture, said canister comprising: a hollow tube including two ends; a pair of caps for closing said two ends; cooperable latch means on said two ends and on said caps for securing said caps to said ends; a post and post mounting means carried by said caps for holding said post centrally within said hollow tube, said post including a cross-sectional dimension slightly smaller than that of the aperture of a disc to receive the discs thereover in a stack; a platform on each of said caps about said post; a plurality of spacer rings for placement over said post between adjacent discs in the stack and between each end disc of the stack and the respective platform, each of said rings comprising a ring body and a plurality of arcuate projections extending from each side of said ring body, each of said arcuate projections being generally L-shaped as viewed in the radial direction including a first leg for extending into and engaging the inner diameter of the central aperture and a second leg carrying a support surface for engaging a respective bevel surface; and said hollow tube and said post including lengths such that the stack of computer discs is clamped against movement when said caps are latched to said hollow tube. In a protective package for protecting computer discs having opposite main surfaces, a central aperture and a pair of bevel surfaces extending from the main surfaces into the central aperture, in which spacer rings are alternately positioned between the discs to form a stack positioned by a central post through the rings and discs and mounted within a container by a pair of n structures, the improvement wherein: each of said rings comprises at least one surface on each side thereof for engaging only the bevel surface of a respective disc; each of said rings comprises a ring body and a plurality of arcuate projections extending from each side of said ring body; and each of said arcuate projections being generally L-shaped as viewed in radial section and including a first leg for extending into engagement with the inner diameter of the central aperture of a disc and a second leg carrying a support surface complemental to a bevel surface for engaging a bevel surface, said support surface constituting said at least one surface on each side of the ring. A spacer ring for receiving a post therethrough and spacing a pair of discs, each of the discs having a pair of main surfaces, a central aperture for receiving the post, and a pair of bevel surfaces each extending from a respective main surface into the central aperture, said spacer ring comprising: a ring body; and a plurality of arcuate projections extending from each side of said ring body, each of said arcuate projections being generally L-shaped as viewed in radial section and including a first leg for extending into and into engagement with the inner diameter of a central aperture of a disc, and a second leg carrying a surface complemental to and for engaging a bevel surface of a disc.
