- an attachment wall defining at least one thread for threadingly engaging said container wall thread;
- an occlusion wall closing said attachment wall to occlude said container opening when said closure is in said closed position;
- and
- a continuously curving, peripheral, finger-engaging surface which defines (1) a plurality of circumferentially spaced protuberances projecting laterally in relation to said attachment wall, (2) a finger-receiving recess between two adjacent protuberances, and (3) a finger-engaging rib projecting laterally from each of said protuberances, each said protuberance having a portion that is wider than said rib projecting therefrom and being of reduced width at said rib where said protuberance merges smoothly into said rib.
