Abstract
Abstract A closure for a container for use in resisting child opening thereof and for recording an act of tampering therewith. This closure has an outer cap and a liner and an inner cap coaxially disposed along a common axis. The inner cap has an outer surface with peripheral groove portions and axial groove portions. The outer cap has an inner surface with a pair of radially protruding spikes which are received and travel in the groove portions for resisting child opening thereof. The liner has a shearable, indicia-marked top foil and a top adhesive attached to the interior surface of a top transparent end wall of the outer cap, and has a bottom, indicia-marked foil with a bottom adhesive attached to the exterior surface of a top end wall of the inner cap, and has an adhesive strip disposed between the two foils, for recording an act of tampering therewith.
