The present invention relates to a screw-on, manually operated sprayer and container. The sprayer has an inside threaded sprayer neck and the container has an outside threaded container neck upon which the inside threaded sprayer neck is attached. The present invention relates to the improvement of providing a child-resistant safety feature. This feature is a non-flexible collar attached to the outside of the sprayer neck and adapted to freely rotate about the sprayer neck to inhibit undesired unthreading or threading of the sprayer neck from or to the container neck. The collar has a continuous sidewall, an open top with a top rim, an open bottom with a bottom rim, positioning means located on the collar to maintain a predetermined position of the collar relative to the sprayer neck, antiremoval means located on the collar to prevent removal of the collar from the sprayer neck, and at least one flexible engagement means located on the sidewall.
