Abstract
A tamper-evident closure includes a cap having a plug, a skirt, and a locking member. The cap and skirt have seats in which a first portion and a second portion of the locking member are arranged. Upon first opening, as the cap moves longitudinally away from the skirt, the lower edge of the cap passes over the first portion longitudinally so that, upon reclosing the tamper-evident closure, the first portion positions in an obstructive manner between the lower edge of the cap and an upper edge of the skirt.
