A container assembly comprising a container for containing fluid, and a container closure. The container includes a neck having a mouth therein for passage therethrough of liquid in the container, and a flange circumscribing and extending radially outwardly from the neck of the container. The flange includes a generally downwardly facing surface. The container closure comprises a closure cap portion adapted for releasable connection to the neck of the container. The closure cap portion comprises a generally annular-shaped skirt, and at least three protrusions extending generally radially inwardly from an inside surface of the skirt. The protrusions are circumferentially spaced from each other along the inside surface of the skirt. The protrusions of the closure cap portion and the flange of the container are configured for a resilient snap-fit engagement of the protrusions with the generally downwardly facing surface of the flange.
