ABSTRACT:
A flap is hinged on a container closure to swing between open and closed positions relative to a dispensing opening in the closure. When the flap is closed, upstanding ribs shield the free edge of the flap. A lift tab projects outwardly from the free edge of the flap and extends between the ribs to facilitate swinging of the flap to its open position. The flap is held releasably in its closed position by virtue of the ends of the ribs engaging the side edges of the tab with a snap fit and also by virtue of straight sections of the ribs engaging straight sections on the free edge of the flap with a snap fit at areas located adjacent the tab.
