Abstract
Abstract A package closure includes a stopper adapted to be sealingly engageable with the opening of the package. The closure also includes a frangible member adapted to simultaneously seal the opening and carry the stopper in a disengaged position relative to the opening. Preferably, the stopper is engageable with the package opening in a child-proof manner. Breaking of the frangible member permits the child-proof package to be initially opened without requiring the package user to struggle with the child-proof stopper. The package contents may then be transferred to a package not having child-proof sealing means. Easy access to the contents of the package by the elderly or handicapped is thereby promoted.
