Abstract:
1. A device of single-piece, molded plastic construction for releasably holding an optical disc having two disc sides, an outer circular-shaped disc rim and a central disc opening and for substantially covering one of said disc sides while leaving the other of said disc sides uncovered, said device comprising a double-sided, plate-like cover and disc retainer structure projecting outwardly from one side of said cover for entering the central disc opening of an optical disc and frictionally engage said optical disc to provide a releasable connection between said optical disc and said device, said cover having cover segment portions with outer peripheral edges extending along spaced portions of the outer disc rim of said optical disc when said optical disc is releasably connected to said cover, and said cover defining spaced, inwardly extending notches between said cover segment portions exposing spaced areas of said optical disc extending inwardly from said outer disc rim to allow manual engagement of said rim when separating the device and the optical disc, and flange segments of substantially uniform height and thickness extending outwardly from the outer peripheral edges of said cover segment portions in the direction said disc retainer structure projects outwardly from said cover, said flange segments partially surrounding and spaced from said movable disc retainer structure, said flange segments terminating at said notches and extending along separate spaced arcs of a circle larger than said outer circular-shaped disc rim whereby said flange segments are immediately adjacent to but spaced from the outer circular-shaped disc rim when the optical disc is releasably connected to said cover, said flange segments extending outwardly a distance slightly greater than the thickness of said optical disc, the outer periphery of said device being rounded at the locations of said flange segments, and said flange segments being free of outwardly extending projections or other structure to facilitate the placement of said device and any optical disc held thereby into a retention sleeve, said disc retainer structure including at least one flexible retention member manually engageable by a user simultaneously with manual engagement of the outer disc rim by the user at the location of said two notches to simultaneously apply with a single hand a pushing force on said at least one flexible member and a force on the outer circular-shaped disc rim at both of said locations opposed to said pushing force to cause separation of the device from the optical disc while retaining the optical disc in hand.
