Abstract

The present invention provides a compact disc container for accessing compact disc. The compact disc container includes a base, a long rod fixed on and supported by the base, a supporter having a through hole for the long rod to pierce through, a housing having a bottom tightly combined with the base, and a top lid tightly combined with the top cover of the housing. There is a fixed hole on the top lid for the long rod to be inserted so as to support the long rod. An O-ring is equipped between the top lid and the housing and between the base and the housing to enhance tightness. The compact disc container uses the long rod to pierce through the center hole of compact discs so to accept the compact discs and uses the tight combination between the top lid and the housing to maintain air tightness so as to keep the contained compact discs from any environmental pollution.
