A reusable closure for placement within the neck of a returnable and reusable container for liquid includes an improved sealing device for preventing contamination of the container. The sealing device achieves a tight seal between a ball and a valve seat within the closure. A cap abutment or spring may optionally be provided to further enhance the tightness of the seal.
