Abstract
A one-piece closure with a snap-on hinged type closure provided with a safety band. When the safety band is still intact, the closure cannot be opened. Once the safety band has been removed, the closure is movable to a lower position relative to the upper edge of the container neck by rotation about a threaded container neck or by downward axial movement. While the closure is in its upper position and the safety band is intact, a catch engages underneath a projection on the base of the closure and prevents the cap from being opened. When the closure is in its lower position, the upper edge of the container neck releases the catch from behind the projection and the sealing cap can be opened. While the safety band is still intact, interaction of an external ratchet-like serration on the container neck and an internal serration on the safety band may prevent the closure from being rotated.
