A filler neck cap is provided for closing a threaded filler neck of a tank. The cap includes a housing having threads for engaging the filler neck, a seal for sealingly engaging the filler neck upon rotation of the housing in a first direction, and a handle for rotating the housing relative to the filler neck. The handle includes a top wall and an appendage directly appended to the underside of the top wall and cantilevered downwardly therefrom at a point spaced apart from the axis of rotation of the handle. The cap further includes a delayed actuation mechanism for providing a lost-motion driving connection between the handle and the housing. The delayed actuation mechanism includes an annular ring engaging the housing and a driven lug appended to the annular ring. The driven lug engages a terminal portion of the appendage during rotation of the handle about its axis of rotation to provide the driving connection between the handle and the housing.
