ABSTRACT:

BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
The present invention relates to a casing for a disk-shaped item, especially for a compact disk, having a base part, which is adapted to receive and hold said item, and having a cover, which is pivoted on the base part. This invention further relates to a method and a device for manufacturing said casing.
2. Prior Art
Casings of this type are already known and they are normally made of a plastic material. The casing cover has two lateral tabs, free ends of which are pivoted at the base part of the casing. If such a casing falls e.g. on the floor, then one of the tabs breaks off very easily and such a casing is then no longer usable. In the course of the recycling of such plastic casings further problems arise.
OBJECT OF THE INVENTION
The object of the present invention is to eliminate said disadvantages as well as further disadvantages of the prior art.
