Abstract: A device for dispensing pills one at a time or one dose at a time includes a unit chamber fittable within/integral with the rim of a bottle. The unit chamber includes a plurality of radial projections which project inwardly to define discrete pill holding areas. The distance between adjacent radial projections is slightly larger than the width of the pill sought to be contained and dispensed by the container. As the bottle is inverted, pills will fall into the pill holding areas, one pill or dosage amount per area. A dispensing cap is rotatable relative to the unit chamber. A single pill-width window in the cap is positionable opposite the pill holding areas of the unit chamber. When a pill is meant to be dispensed, the bottle is inverted or angled downward, and a single pill in the pill holding area opposite the window falls out of the bottle.
