Abstract
A child-resistant package with a snap-on closure comprising a container having a neck finish including an annular retaining bead having at least one notch therein and a closure having a top wall and peripheral skirt, the skirt having a lifting tab on the outer surface thereof and a radially inwardly extending locking lug on the inner surface thereof adjacent the external lifting tab. The closure includes a tamper indicating band attached to the skirt by a plurality of circumferentially attached bridge portions. The band is formed with a plurality of circumferentially spaced vertical ribs. The finish of the container includes a plurality of circumferentially spaced vertical ribs such that when the closure is applied to the container, the ribs on the closure and the ribs on the container interengage in such a manner that the locking lug on the container can not be aligned with the notch on the container and prevents the closure from being rotated to align the locking lug from being aligned with the notch on the container until the band is partially severed from the closure.
