An article dispenser having a container or container mating portion and a dispenser control member, the former being in coaxial contiguous engagement with the latter for relative slideable motion therebetween. In the preferred embodiment of the invention disclosed herein, the slideable motion is in a vertical direction substantially parallel to the access of the container. A flexible member is provided which may be made integral to either the container portion or the dispenser control member and provides positive locking control for opening and closing the dispenser and provides means for making a substantially permanent engagement between the container portion and the dispenser control member. In addition, the dispenser control member provides a plurality of channels one of which includes a bead or rise and the upper ring portion of the container member provides an undercut or wedge-shaped tab which is designed to reside in these channels. The particular channel in which it resides at any one time determines whether the invention is being used in a child-resistant or a non-child-resistant mode. Transfer of the wedge-shaped bead in these channels is accomplished by simply rotating the dispenser control member relative to the container portion to place that bead either in a channel having no rise or bead for restraining the movement of the dispenser control member for opening and closing the article dispenser or in a channel having such a bead for introducing such constraint. The degree of constraint is determined by the thickness of the bead in a channel within the dispenser control member to render the article dispenser child-resistant in this mode.
