Abstract
A disc package (10) includes a generally circular base (18), a core (34) extending upwardly from the base (18), and a cover (44) having a peripheral skirt (48) extending to a lower rim portion (50). The circular top is fastenable to the upper end portion (38) of the core (34). A resilient gasket (80) is removably attached to the lower rim portion (50) of the peripheral wall (26) and provides pressed resilient slidably sealing contact to prevent entry of dust into the disc package. Structures are also provided whereby the interior of the disc package (10) can be filled with a dust free gas. A plurality of covers (44) can be stacked, one atop another, without seizing to one another. Low outgassing materials are utilized to protect the stored discs (12a-12z) from damage.
