Abstract: A tamper resistant closure including an inverted cup shaped shield for shrouding the cap of a bottle to restrict access to such cap for opening of the bottle. The shroud is formed with an aperture through which a stem on the cap projects and is held non-releasably locked in covering relationship on such cap by means of a compressible or resilient fastener conical head, the head being operative to compress and pass through such aperture and to then expand to nonreleasably lock the shroud in covering relationship on the cap.

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.
