Abstract: A cap and container assembly which is both tamper-proof and child-resistant comprises a container neck with first and second external beads, the first bead extending only part way round the neck and having a lug midway between its ends, and the cap has an internal bead with a gap in it matching the lug and also has a tear-off strip connected to a shoulder that engages under the second bead on the neck so that even after removal of the strip the cap still has to be turned to bring the gap opposite the lug before it can be removed. The shoulder may be on an anchor band which fits permanently under the second bead. The cap may be permanently joined to this anchor band by a hinge web.
