Abstract
An improved safety closure device and a method for making same are described. A cylindrical closure element adapted to close the mouth of a bottle or the like by frictional engagement with the interior facing surface of the mouth is joined via a cap portion to a cylindrical retainer collar, extending substantially coaxial with the closure element, by an intercoupling means comprising a tabbed tear strip and a tether strip. The tear strip and the tether strip are integrally formed in a helical configuration extending from the closure element to the collar. The tether strip and tear strip are joined by a pair of frangible webs of a preselected thickness which permit the tear strip to be manually removed. The collar and intercoupling section, including the cap portion thereof, are molded as a unitary structure. The closure element is formed as a separate unitary structure and is secured mechanically to the intercoupling means preferably by a snap-fit means about the periphery of one end of the closure element.
