Security seal apparatus
First Claim
1. A security seal apparatus for restricting access to an aperture formed centrally in a work piece carrying sensitive information thereon, said assembly comprising:
- a rigid pad for covering said one side of said work piece and including a stem projecting from one side thereof for projecting through said aperture when said pad is positioned in covering position on said one side;
a fastener plate for overlying said pad, being of sufficient size to project beyond the peripheral edges of said aperture and being formed centrally with and opening; and
,a lock formed on the free end of said stem, said lock being characterized in that it passes freely through said opening and is reponsive to projection beyond the periphery of said opening to non-releasably lock said pad and fastener plate together to seal said pad and plate in sealing engagement in said aperture whereby said stem must be severed to remove said pad from said one side thus leaving perceivable evidence that access has been had to said work piece.

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.
