CASE FOR DISC-SHAPED OPTICAL RECORDING MEDIUM SUCH AS CD, DVD OR THE LIKE |
摘要 |
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). |
