Publication number: 20100095962Abstract: 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.Type: ApplicationFiled: August 10, 2009Publication date: April 22, 2010Inventor: Winston Z. Lu
