Tamper-resistant container assembly

A tamper-resistant container assembly having a substantially smooth unstepped outer profile comprising a closure and a container body wherein the closure has a cap part, a depending skirt with an internal screw thread, teeth at the lower edge of the skirt, a safety band below the skirt, frangible tell-tale means connecting the skirt to the safety band, teeth on the upper edge of the safety band and a plurality of discontinuous ratchet shaped inner beads on the safety band and wherein the container body has a mouth, a neck below the mouth, an external screw thread on the neck, and a continuous outer bead below the screw thread and a plurality of discontinuous ratchet shaped outer beads below the continuous outer bead;

• wherein the innermost portions of said outer beads and the outermost portions of said inner beads are disposed below said continuous outer bead and inside its largest periphery when said closure is engaged on said container body;
• the arrangement being such that (a) the closure can be applied to the container body for the first time simply by screwing the closure on, the safety band being driven on with the cap part by engagement of the teeth on the cap part with the teeth on the safety band, (b) the closure can be removed from the container body for the first time simply by screwing the closure off, the safety band being prevented from turning with the cap part by positive engagement of the discontinuous ratchet shaped beads on the band with the discontinuous ratchet shaped beads on the container body so that the frangible tell-tale means break, and (c) due to the fact that the discontinuous outer ratchet shaped beads on the container body are below and inside the perephery of the the continuous bead, the safety band can fall to the lower part of the container neck to give evidence that the closure may have been removed from the container body but cannot fall off of the container when the cap part is removed.
