A container closure includes an adapter formed from a first thermoplastic material and a valve formed from a second thermoplastic material. The adapter and valve are bonded together in a multi-material molding process to form an adapter and valve assembly. The adapter and valve assembly is directly fastened to a base to form the closure.
