Abstract
The present invention relates to a disk case made of plastics material which comprises a case, body and a cover which can be snapped locked to the body to enclose a disk. The disk is retained by the body of the case by a snap button. The snap button has a lip which engages at the central aperture of the disk to provide a downward force onto the upward surface of the disk. The snap button is mounted on a flexibly ridged arm extending from the body of the case and allows for the snap button to be moved from an engaged to a disengaged condition with the disk.
Claims25
A media storage disk case, for a media storage disk of a kind including a central aperture, said case comprising:
- a body portion including a substantially planar base,
- one push button receivable in the central aperture of the disk, the one push button cantilevered from said base by at least one resiliently flexible arm extending at an angle away from said base,
- said one push button providing a catch to, when the disk is received by said push button, engage on an outwardly facing surface of the disk, said catch provided to engage the outwardly facing surface of said disk at no more than half of the perimeter of said central aperture, wherein any structure of the disk case that is receivable in the central aperture of the disk, including the one push button, is without a catch along the other half of the perimeter of said central aperture to engage on the outwardly facing surface of the disk when the disk is received by the push button,
- an upward support member to locate with a downwardly facing surface of the disk when engaged with said push button, to support said disk above said base,
- a longitudinal disk support member which when the disk is engaged with said one push button is engagable with an edge of said disk to prevent release of said disk from said catch,
- wherein when a disk is engaged with said one push button and said one push button is depressed, it moves from a first condition where said catch is engaged with the outwardly facing surface of said disk, to a second condition towards said base where said catch is released from the outwardly facing surface of said disk, to allow release of said one push button from the central aperture.
A media storage disk case assembly, comprising:
- a media storage disk of a kind including a central aperture, and;
- a case, said case comprising:
- a body portion including a substantially planar base,
- one push button located in the central aperture of the disk, the one push button cantilevered from said base by at least one resiliently flexible arm extending at an angle away from said base,
- said one push button providing a catch to engage on an outwardly facing surface of the disk, said catch to engage the outwardly facing surface of said disk at no more than half of the perimeter of said central aperture, wherein any structure of the disk case that is received in the central aperture of the disk, including the one push button, is without a catch along the other half of the perimeter of said central aperture to engage on the outwardly facing surface of the disk,
- an upward support member to locate with a downwardly facing surface of the disk to support said disk above said base,
- a longitudinal disk support engagable with an edge of said disk to prevent release of said disk from said catch,
- wherein when said one push button is depressed, it moves from a first condition where said catch is engaged with the outwardly facing surface of said disk, to a second condition towards said base where said catch is released from the outwardly facing surface of said disk, to allow release of said one push button from the central aperture.
