Patent attributes
A compact disk (CD) box structure includes a seat having an upward extended central post, which has an externally threaded upper end; a knob having a downward extended and internally threaded hollow central column for screwing to the externally threaded upper end of the central post, so that CDs stacked on the seat around the central post can be immovably held to the seat by the knob; a protective barrel being a cylindrical container with a closed bottom and an open top, so that the seat having CDs stacked thereon can be fitly received in the protective barrel; and a top cover being connectable to a flange around the open top of the protective barrel by high-frequency heating or heat melting to seal the CDs in the protective barrel. The CDs stored in the CD box are not only well protected against dust, but also scratches possibly caused by vibration.
