The present invention relates to sleeves Fig. 1 Fig. 2 cases or envelopes Fig. 3 for any type of disc (8) making it possible concomitantly to combine protection of the sleeve (1) itself, and classifying with 2 holes (2) on the sides of the standard jacket-type sleeve Fig. 1 Fig. 2. Procedure: 1) Extraction of the disc is made easy by the presence on 1 only of the faces of the sleeve (1) of an oblong slot situated on the middle axis of the sleeve, pointing from the centre towards the exit, enabling the disc (8) to be easily moved with one finger Fig. 1. 2) Insertion of the disc is faciliated by a cutout (4) in the edge of the same face (Fig. 1) having a shape allowing fast insertion of the disc and its automatic positioning. 3) The double sleeve (1) Fig. 2 benefits from a system for faster extraction and insertion of the disc (8) obtained by joining up the slot (3) and the cutout (4) e.g. Fig. 2. 4) The sleeve (1) Fig. 1 can also benefit from faster extraction and insertion of the disc (8) Fig. 2. Upkeep of the disc (8) is achieved by the presence of a brandname or similar suitable cleaning material or fabric of TEIJIN type (5) which can be stuck, lined, flocked etc. on the inside faces of the sleeves Fig. 1 and 2 as well as to the cases and envelopes Fig. 3. <IMAGE>
