Abstract
A closure device for both smooth necked and threaded necked containers includes a tamperproof cap frangibly affixed to the container for selective removal by manipulation of the cover. Upon breaking the tamperproof seal by cover manipulation, the cap may be retained within the cover to avoid disposal problems and to serve as a sealing component when the container is resealed after initial opening occurs.
