Abstract
An enclosure for securing a disc having a central aperture includes a base and a pivotable cover. A two part disc securing rosette has a first part on the base including at least two upstanding, circularly spaced apart segments with arcuate outer peripheral surfaces dimensioned for engaging the central aperture of a disc and a second part including at least two elongate, upstanding ribs extending radially from a position on the cover which is centered on the segments on the base, the number of ribs on the cover corresponding to the number of segments on the base, the ribs being positioned and dimensioned such that, when the enclosure is closed, the ribs on the cover enter the first part radially inwardly of the segments with the ribs contacting the radially inside surface of the corresponding arcuate segments for bracing the arcuate segments against breakage.
