The inner sidewall has an internal thread for engaging the neck external thread. An outer sidewall for gripping by a user has first and second pairs. The second pair of segments are hinged to the inner sidewall for depressably flexing from relaxed condition to a flexed condition and bear a second pair of engagement features. In the installed condition of the cap and relaxed condition of the second pair of segments, the first pair of engagement features and second pair of engagement features are positioned to collide to block an unscrewing rotation of the cap. An upper web joins the inner sidewall and the outer sidewall first pair of segments. A pair of respective hinges between the second pair of segments and the inner sidewall merge with the inner sidewall at a location recessed from an upper end of the inner sidewall.
