Abstract
A closure for a container includes a main body portion that is constructed and arranged to be secured to a container, such as by a threaded engagement. The main body portion has a dispensing orifice defined therein that is configured to permit material flow from the container. A lid portion is hingedly mounted to the main body portion and is movable between a first, open position wherein material may be dispensed from the container through the dispensing orifice and a second, closed position wherein the dispensing orifice is blocked by the lid portion. Venting structure is defined in the main body portion for permitting for permitting outside air to enter the container when an underpressure condition exists within the container, as may be expected to occur when the container is subjected to a change in altitude or temperature.
