ABSTRACT:
A threaded metal closure plug and closure combination for liquid storage containers, such plug being specially formed for receiving a hand applied torque force. The plug is cup shaped with a bottom wall surrounded by an upstanding cylindrical sidewall, the lower major portion of which is threadedly engaged within an upstanding container opening neck. The upper end of the plug sidewall forms a seat for a resilient sealing gasket and that end terminates in a circumferential outwardly extending lip having a peripheral free edge. Portions of that free edge are deformed downwardly at circumferentially spaced intervals to form radially outwardly facing hand gripping surfaces for convenient and effective hand rotation of the plug.
