This relates to closures for containers such as jars and the like wherein the neck finish of the container is provided with an annular locking ring and a skirt of the closure is provided with a series of circumferentially extending and circumferentially spaced lugs for locking the closure in place. The closure may be entirely formed of a resilient plastic or may include only an annular rim which carries a metal panel forming the general end wall of the closure. The skirt is molded so as to define a tab which may be engaged by one\s thumb and folded or hinged radially outwardly so as to facilitate application of the necessary lifting force to remove the closure from the container. There are several different tab formations and at least certain of the tabs have associated therewith tamper indicating means.
