Dual disc adapter with downward sloping outside corner wedges

DETAILED DESCRIPTION The inventors have found that these two diverse sets of needs can be met by a single adapter insert which can function either as an added disc holder for use in a jewel case, or as a disc holder in a paperboard optical disc package.
Enabling a single adapter insert to fulfil both functions simplifies production and reduces production costs.
The dual purpose adapter insert of this invention, when used in a jewel case, enables the jewel case to hold two optical discs, instead of the customary one disc, with both discs held safely, securely, and spaced apart from one another, thereby avoiding damage which might arise from the discs contacting one another.
When used in a paperboard package, the corners of the adapter insert are easily inserted into apertures in the package, so that the adapter insert is securely held in place without the use of adhesive.
The adapter insert can be used either with manual or automated assembly procedures.
When used in a jewel case, the adapter insert of the present invention supports and retains a compact disc inside an enclosure, e.
g.
the lid section of a jewel case.
The adapter insert is made to be held in place by the inwardly extending lid tabs found in standard jewel cases.
The adapter insert is sufficiently flexible to be bent in the manner necessary to insert it beneath the tabs, yet sufficiently stiff to hold and support an optical disc in the required manner.
A retainer hub in the center of the adapter insert frictionally fits into the center bore of the optical disc, while a portion of the adapter insert near the retainer hub supports the center portion of the disc.
In addition, the adapter insert provides peripheral support bosses which support the edge of the disc.
Locator recesses on the adapter insert receive the lid tabs and positively position the adapter insert in the lid section.
The combination of the locator recesses and the lid tabs, along with elevated surfaces provided by the retainer hub and peripheral support bosses, serve to hold the adapter insert in the lid section and maintain an air gap between the two discs in the jewel box when the box is closed
