Abstract
A plastic screw cap for carbonated beverage bottles having standard necks. Screwing the cap on forces its antitamper skirt over a shoulder of the bottle neck. Unscrewing the cap causes the skirt, or a portion connecting the skirt to the main body of the cap, to break. The skirt has a throat whose I.D. (inside diameter) is smaller than the O.D. (outside diameter) of the bottle threads, but is large enough so that the cap can, under light pressure, wobble or rock down the neck to seat the cap properly for screwing on. The skirt may have a flap which becomes effective to decrease the effective skirt diameter when the cap is being unscrewed.
