Security seal apparatus

Abstract

There is disclosed a security seal apparatus for securing information recorded on a recording medium such as a floppy disc or recording tape which incorporates an aperture therein. The security seal apparatus includes a circular rigid pad projecting beyond the edges of such aperture and formed centrally with a post for projecting through such aperture. The post is formed on its free extremity with an enlarged-in-diameter conical lock head having its base of a cross-section less than the cross-section of the aperture. A fastener plate is provided with a central opening having a diameter slightly less than the base of such conical lock head so that such fastener plate may be pressed onto such lock head causing the base of the conical lock to be compressed radially inwardly whereby the lock will pass through such opening and expand radially outwardly to overlie the peripheral edges of such opening and lock the fastener in position. In certain embodiments, the bottom of the fastener is dished out slightly to form a somewhat annular conically shaped cavity opening downwardly toward the pad. Also, in one embodiment the fastener plate is dished outwardly away from the pad to engage under the base of the conical fastener.
