Abstract
A security device for preventing theft of a disk such as a CD or DVD from a storage container having a base and a hinged lid, a pedestal including a button having retainers thereon that retract when the button is depressed for releasing the disk, and a wrapper holding the container closed. The device has a cap member and rearwardly extending flange and stem members. Release of the disk from the pedestal and removal of the disk through a slit made in the wrapper is blocked by the cap member preventing depression of the button, the flange member also positively holding the disk on the pedestal when the lid is deformed against the device. Preferably the device is releasably retained in a seated condition when the lid of the container is open. Also disclosed is a method for securing a disk container.
Claims29
The combination of a disk storage container having a base portion and a lid portion, a forwardly projecting pedestal of the base portion including a button portion having spaced apart segments for retentatively engaging a central opening of the disk, segments of the button portion moving inwardly for releasing the disk upon depression of the button portion, with a security device, the security device comprising:
- (a) a cap member for blocking contact between the lid portion and the button portion;
- (b) a flange member rearwardly extending from the cap member for contacting the disk on opposite sides of the button portion when the cap member is seated over the button portion;
- and
- (c) a stem member projecting rearwardly from the cap member within the flange portion for guiding the device into its seated condition.
A security device for a disk storage container having a base portion and a lid portion, a forwardly projecting pedestal of the base portion including a button portion having spaced apart segments for retentatively engaging a central opening of the disk, segments of the button portion moving inwardly for releasing the disk upon depression of the button portion, the security device comprising:
- (a) a cap member;
- (b) a flange member rearwardly extending from the cap member for contacting the disk on opposite sides of the button portion when the cap member is seated over the button portion;
- (c) a stem member projecting rearwardly from the cap member within the flange portion for guiding the device into its seated condition;
- and
- (d) means for releasably holding the device in its seated condition.
A security device for a disk storage container having a base portion and a lid portion, a forwardly projecting pedestal of the base portion including a button portion having spaced apart segments for retentatively engaging a central opening of the disk, segments of the button portion moving inwardly for releasing the disk upon depression of the button portion, the security device comprising:
- (a) a cap member;
- (b) a flange member integrally formed with the cap member and rearwardly extending therefrom not less than approximately 3 mm from a central region of the cap member for contacting the disk on opposite sides of the button portion within an outside diameter of not more than approximately 20 mm when the cap member is placed over the button portion, the flange member being formed for clearing a button diameter of up to approximately 17 mm;
- (c) the cap member projecting outwardly from the flange member to an outside diameter of between approximately 20.5 mm and approximately 25 mm for facilitating removal of the security device;
- and
- (d) a stem member integrally formed with the cap member and projecting rearwardly from the cap member within the flange portion for blocking inward movement of the segments of the button portion when the device is in place over the button portion, the stem member tapering inwardly toward an end extremity thereof for facilitating insertion of the stem member between inward extremities of the button segments.
A method for securing a disk storage container against theft of a disk therefrom without removing a wrapper of the case, the container having a base portion and a lid portion, a forwardly projecting pedestal of the base portion including a button portion having spaced apart segments for retentatively engaging a central opening of the disk, segments of the button portion moving inwardly for releasing the disk upon depression of the button portion, the method comprising:
- (a) providing a security device having a cap portion, a flange portion rearwardly extending therefrom, and a stem portion projecting rearwardly from the cap member within the flange portion;
- (b) with the case open and holding the disk seated on the pedestal, installing the security device by inserting the stem member between inward extremities of the button segments and lowering the device to bring the flange portion into proximity with the disk on opposite sides of the button segments;
- (c) closing the container;
- and
- (d) applying a wrapper to the container to hold the container closed, thereby securing the container from theft by blocking depression of the button segments by the deflection of the lid portion and blocking inward movement of the segments of the button portion.
A security device for a disk storage container having a base portion and a lid portion, a forwardly projecting pedestal of the base portion including a button portion having spaced apart segments for retentatively engaging a central opening of the disk, segments of the button portion moving inwardly for releasing the disk upon depression of the button portion, the security device comprising:
- (a) a cap member;
- (b) a flange member rearwardly extending from the cap member for contacting the disk on opposite sides of the button portion when the cap member is seated over the button portion, the flange member having an inside diameter of approximately 17 mm and an outside diameter of approximately 19.5 mm for contacting the disk within an outside diameter of not more than approximately 20 mm;
- and
- (c) a stem member projecting rearwardly from the cap member within the flange portion for guiding the device into its seated condition, the stem member tapering inwardly toward an end extremity thereof for facilitating insertion of the stem member between inward extremities of the button segments.

- (a) a cap member;
- (b) a flange member rearwardly extending from the cap member for contacting the disk on opposite sides of the button portion when the cap member is seated over the button portion, the flange member having an inside diameter of approximately 17 mm and an outside diameter of approximately 19.5 mm for contacting the disk within an outside diameter of not more than approximately 20 mm;
- and
- (c) a stem member projecting rearwardly from the cap member within the flange portion for guiding the device into its seated condition, the stem member having reduced cross-section proximate a root extremity thereof for engagement by the segments of the button portion for releasably holding the device in its seated condition.
