A tamper-proof closure for a container including an endwall and an annular, threaded sidewall. The sidewall includes an internal projection for mating with a part of the container to prevent turning of the closure when the closure is mounted on said container. A tear tab is provided on the sidewall radially outwardly of the projection. The sidewall includes tear facilitating portions on circumferentially opposite sides of the tear tab to enhance tearing of the sidewall on opposite sides of the tear tab to permit the tear tab and the projection to be swung outwardly to a removed position in which the closure can be turned. Another aspect of the invention includes a method of making the closure.
