ABSTRACT:
A tamper-evident, snap-on, screw-off closure is used with a specially shaped container neck. The neck has at least one first helical thread on a neck stretch portion, and at least one external ratchet tooth on a locking wall portion below the neck stretch. The closure has an upper skirt having at least one second helical thread mating with the first helical thread of the neck and a lower skirt with at least one internal ratchet tooth shaped and positioned to engage the external ratchet tooth when the closure is applied to the neck. The teeth formed on the skirt interior and neck exterior are arranged to provide at least one circumferentially extending stretch of the tamper-evident band where the teeth are not engaged. A line of weakness extending vertically through the disengaged stretch of the tamper-evident band is ruptured when the closure is unscrewed from the neck.
