摘要:
A compact disc case including lower and upper cases fixed by snap joints with enough space left in between for storing a compact disc. The lower case has at least three cushion holders to support the compact disc up above the bottom, and for preventing improper insertion of the case into a disc player, a control groove or a control shell is provided at least in either one of the upper and lower cases. The front edge wall of the lower case is provided with engagement holes, while the upper case has pawls to be engaged with the engagement holes, and also latches and latch locks engaging with each other are formed at the rear of the upper and lower cases. By means of this structure, the case with a compact disc in it can be inserted into a disc player for use without any improper insertion, and since the upper and lower cases can be readily detached from each other, the disc can be taken out and cleaned easily when the information-recording side gets dirty due to long periods of use or by accident.
