Abstract
A molded 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 supported on the bottle by a cylindrical retainer collar extending substantially coaxial with the closure element. The retainer collar is connected to the closure element by 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 one or more turns 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 are molded as a unitary structure. The closure element is molded as a separate unitary structure and is secured mechanically to the intercoupling means by snap-fit about the periphery of one end of the closure element.
