Abstract
A medicine bottle unit having a closure for indicating dosage and other information which changes automatically as the closure is rotated on the bottle of the unit. The closure includes an outer cap and an inner member within the cap. The cap and inner member have cooperable indicia thereon. The inner member moves with the cap as the cap is rotated in one direction on the bottle. However, the cap moves relative to the bottle and the inner member when the cap is rotated in the opposite direction on the bottle, thus assuring a change in the information represented by the indicia on the cap and the indicator on the inner member, or by indicia on the inner member visible through a hole in the cap. Several embodiments of medicine bottle unit are disclosed.
