DISK CASE

PROBLEM TO BE SOLVED: To prevent a disk from droping out or being pilferred even without sealing it with an adhesive, by connecting the upper cover which can be folded and superposed on one end of the lower cover and turning up it onto the lower cover at the other end of the lower cover arranged at the opposite side against the connection side. SOLUTION: An upper cover 2 is connected to one end of the lower cover 1 and folded to superpose onto the lower cover 1 through a turning-back line 6a to put the insertion holder 3 between the lower cover 1 and the upper cover 2. A circular outer aperture 7a is formed at the nearly central part of the upper cover 2. The insertion holder 3 is connected to the other end of the lower cover 1 oppositely arrangea against the connection side of the upper cover 2 and the insertion holder 3 is inserted in a protection bag 5 containing the disk 4 to keep it together with the protection bag. It is preferable that the insertion holder 3 has a length to position near the turning-back line 6a between the lower cover 1 and the upper cover 2, at the front end thereof, when turned up onto the lower cover.
