Abstract
A closure is provided for a container having an opening. The closure includes a base for mounting to the container around the opening. A dispensing valve is disposed across the base and defines an orifice which opens to permit flow therethrough in response to increased pressure within the container and closes to shut off flow therethrough upon removal of the increased pressure. An outer member is included on the base outwardly of the valve. The outer member defines at least one dispensing aperture and functions as a flow baffle and/or guard for protecting the valve.
