Abstract
An indicating device suitable for indicating the number of dosages of a substance that have been dispensed from or remain in a container includes at least one first indicator member incrementally moveable to a plurality of positions and a second indicator member moveable in response to a predetermined number of movements of the at least one first indicator member. The at least one first indicator member includes primary dosage indicia adapted to indicate the number of dosages of substance that have been dispensed from or remain in the container. The second indicator member includes secondary dosage indicia adapted to indicate that less than a minimum predetermined number of dosages of substance remain in the container. In one preferred embodiment, the primary dosage indicia are configured as numerical indicia and the secondary dosage indicia are configured as color indicia. In another aspect, a device for dispensing dosages of a substance includes a dispenser housing and a container disposed in the dispenser housing. The indicating device is located adjacent to and is actuated by one or the other of the top or bottom of the container. A method for indicating the number of metered dosages of medicaments dispensed from or remaining in the container is also provided.
