This relates to a closure with a drop down tamper indicating and a related container finish. The container is provided with a neck finish which includes below threads (8) thereof a radially outwardly projecting bead (30) which carries a plurality of circumferentially spaced, vertical nibs (32). The closure is constructed to be rotated relative to the container neck finish during the removal thereof and includes a lower tamper indicating band (38) which is secured to the closure skirt by a plurality of rupturable bridges (54). The band has formed on the inner surface thereof a plurality of circumferentially spaced, radially inwardly projecting, axial splines (56) which may be considered as arranged in pairs for receiving therebetween a container nib. The circumferential spacing of each pair of splines is greater than the circumferential extent of a nib so that there is a very loose connection between the nibs and the splines which prevent only rotation of the tamper indicating band when the closure is being removed to open the container. When the bridges rupture, the tamper indicating band is free to drop down below the container neck finish and to seat on the container shoulder (22). The closure cannot be reapplied and the tamper indicating band loosely assembled therewith to give the appearance that the container has not been opened.
