ABSTRACT:
A child-resistant container and closure assembly having a container neck with a first screw thread and two first locking elements located below the first screw thread on opposite sides of the container neck. A closure for the container neck has a second screw thread complementary to the first screw thread, a resiliently deformable skirt, and two second locking elements on opposite sides of the resiliently deformable skirt. The first and second locking elements mutually engage in ratchet fashion when the closure is screwed onto a fully engaged position on the container neck and subsequently block unscrewing of the closure unless a radial pressure is applied to the skirt at positions spaced from the locking elements to deform the skirt to release the locking elements. The first and second threads are two-start, fast-turn threads so that the closure can be moved from a substantially fully disengaged position to a substantially fully engaged position on the neck by rotation through about 180.degree. or less.
