The disclosed invention is a child-proof closure device for a bottle. The device includes a bottle cap which can be placed in sealing disposition with a cap-receiving upper lip on the bottle, and which is removable from the lip of the bottle with rotation and/or upward excursion on and relative to the upper lip of the bottle. The device includes in combination with this cap, a bottom member for fitting over the bottle bottom in releasable snap engagement therewith, and a strap attached between the bottom member and the cap, the bottom member and strap being configured so that the cap cannot be removed from the bottle without first removing the bottom member from the bottle bottom. In certain embodiments of the invention, the length of strap between the cap and bottom member is short enough to restrain upward excursion of the cap and prevent its removal when the bottom member is in place on the bottle bottom. In some embodiments of the invention, the bottom member and bottle bottom are configured to contain means for preventing rotation of the bottom member relative to the bottle bottom so as to prevent rotation and removal of the cap on the lip of the bottle.
