Disclosed is a case (1) with a lid (1a), a portion of box or bottom (1b) hinged by a central portion of the back (1c), as well as circonferential protuberances bearing onto the external edge of the disc-shaped magnetic recording medium. For nesting-removing the disc central orifice, a device is provided which is comprised of a cylindrical platform (2) having a central formation (2a) which is also cylindrical and on which bears the lower surface of said disc. Around a prismatic-hexagonal protuberance (2b), pins or lugs (3) are concentrically conformed. Said lugs (3) have retention teeths (5) which are separated from the base of the central formation (2a) by a distance (H) which is equivalent to the thickness of the recording medium. In a preferred embodiment, an articulation or hinge seal (7) is configured around the cylindrical platform (2) and is integrally molded as a zone having a reduced wall thickness with a groove (7a) and a bead (7b).

L'invention concerne un étui (1) présentant un couvercle (1a), une partie de boîtier ou paroi de fond (1b) articulés au moyen d'une partie centrale du dos (1c) et des saillies périphériques permettant l'appui d'un bord extérieur du support d'enregistrement magnétique sous forme de disque. Un dispositif formé d'une plate-forme cylindrique (2) est prévu pour fixer/libérer l'orifice central du disque, ledit dispositif présentant une configuration centrale (2a) cylindrique sur laquelle vient s'appuyer la surface inférieure dudit disque. Autour d'une saillie prismatique-hexagonale (2b) sont formés de manière concentrique des protubérances ou des tenons (3) présentant des dents de retenue (5) séparées de la base de la configuration centrale (2a) à une distance (H) égale à l'épaisseur du support d'enregistrement. Selon un mode de réalisation préféré, on forme, autour de la plate-forme cylindrique (2), un joint d'articulation ou de charnière (7) l'entourant et moulé de manière solidaire en tant que zone présentant une épaisseur de paroi réduite, ainsi qu'une rainure (7a) et une nervure (7b).
