A snap-on closure prevents flaps from coming unsnapped or popping open during assembly of the closure onto the neck of a container. The snap-on connection between the container and the closure includes a circular groove and a circular rib projecting into the groove. The closure includes dispensing ports such as sifter holes, a pouring hole, and/or a spooning hole which are closed by hinged flaps whic h snap- on the horizontal platform of the closure. The flaps may include plugs which project into their respective dispensing openings and provide a seal against the wal l of the opening. The closure also includes a resilient crush seal which engages the neck of the container to provide a seal between the closure and the container.
