A press-on/pry-off closure (11) includes a separately formed circular end panel (12), preferably composed of metal, and a surrounding nm (13) composed of a flexible plastic, preferably a thermoplastic polyolefin. The end panel (12) is top-side inserted into the rim and secured between a radially inwardly extending ledge (32) on an interior sidewall of a skirt portion of the rim and a plurality of radially inwardly extending panel-retaining formations (30) adjacent an upper edge of the rim.
