A container having a security closure is described, of the type comprising a hollow body (9) with a mouth or neck (10) defining an opening to the interior of the body, the mouth having an outer screw thread and also a first series of ratchet elements (2). A closure (3) adaptable to the mouth of the container so as to close the opening in the body has a closed end and an outer skirt, the outer skirt (18) being formed with an inner screw thread that co-operates with the outer screw thread on the mouth. The closure is also formed with a second series of ratchet elements (21) so that, on screwing the closure onto the mouth, the co-operation between the ratchet elements (12, 21) of the first and second series permits closure of the container, but prevents unscrewing if the closure.
