Abstract
A polymeric closure assembly includes inner and outer shells, and a liner. The inner shell includes a top wall portion and a skirt portion. The top wall portion of the inner shell forms an opening therein. The skirt portion of the inner shell includes a thread formation. The outer shell includes a top wall portion and a skirt portion. The top wall portion of the outer shell forms an opening therein. The liner attaches to an interior surface of the top wall portion of the inner shell and a finish of the container. The liner includes a substrate layer, a separable layer, a foil layer, and an adhesive layer. The separable layer assists in separating the liner into two pieces.
