Abstract

See full text

An indicating device suitable for indicating the number of metered dosages that have been dispensed from or remain in a container includes a base member adapted to be mounted to the container and a cap member moveably connected to the base member. The cap member is moveable relative to the base member along an axial path. A shaft is non-rotatably mounted to one of the cap member and the base member and defines an axis. An indicator member is rotatably mounted on the shaft and is rotatable in at least a first direction. One of the shaft and the indicator member has a helical groove while the other of the shaft and the indicator member has a follower disposed in the groove. The indicator member is moveable relative to the shaft along the axis as the indicator member is rotated in the first direction. In another embodiment, the indicating device includes first, second and third indicator members. In yet another embodiment, the indicating device includes a housing having a longitudinally extending cavity shaped to receive the container and an indicator member disposed in the cavity and having a longitudinally extending wall shaped to surround at least a portion of the container. The indicator member is rotatably mounted within the housing and is rotatable relative thereto about a longitudinal axis. The indicator member includes a driven gear. A drive gear is disposed in the housing and includes a drive portion selectively engaged with the driven gear. An actuator is adapted to move with the container and is selectively engaged with the drive gear.
