Abstract: A security device for attachment to a container having external walls such that a transponder thereon is located externally of or adjacent to one of said external walls so as to avoid being shielded by a metal layer within the container (e.g. the metal layer within a disk such as a CD or DVD). The security device is arranged to trigger an alarm signal if the container is moved within the range of an alarm unit with the security device attached thereto, and has a releasable locking mechanism to secure it to the container such that release of the locking mechanism requires the use of authorized release means. In one embodiments the transponder is located in the vicinity of a window in a metal layer, e.g. at the centre of the disk.

Abstract: Apparatus for holding an article such as a disk, the apparatus comprising a hub (5) for holding the disk; a cap (7) moveable between a first position in which it permits the disk to be received by the hub (5) and removed therefrom and a second position in which it prevents the hub from releasing the disk and/or inhibits removal of the disk therefrom; and a security device (8) engageable with the apparatus so as to interact with the cap to secure the cap (7) in said second position. The cap (7) may be a separate item, hinged to the apparatus or carried by a lid portion of the apparatus.

Abstract: The apparatus comprises a base portion (2) and at least two arms (1) resiliently cantilevered from the base portion (2), the inner ends of the arms (1) forming a button-like member (4) and each having a projection (4A) for engaging on the outwardly facing surface of a compact disk (10) held on the apparatus. Depression of the button-like member (4) causes the projections (4A) to move towards each other until their engagement on the disk (10) is released. An upstand (6) surrounds the disk (10) and is positioned close thereto so as to restrict movement of the disk (10) within its own plane. The inner ends (4) of the arms (1) may be shaped to reduce the risk of forces applied thereto in the plane of the disk (10) causing the disk (10) to be released. Finger recesses (6A) in the upstand may be formed so as to inhibit access to the edge of a disk (10) whilst held by the apparatus but provide access thereto once the disk (10) has been released. 3-arm release mechanisms are also described.

Abstract: A container for housing a CD or DVD, which has a plastics film about the exterior with a security marking formed or attached to the film.

Abstract: A container comprising two identical rigid molded frame members and an initially flat sheet of flexible material adapted to be received and retained in a channel in the frame member.
