Abstract
An indicating device for indicating the number of dosages of a substance that have been dispensed from or remain in a container includes a first housing member having laterally spaced apart first and second guide members and a second housing member. The first and second housing members are moveable relative to each other along a longitudinal axis. The second housing member includes laterally spaced apart first and second guides shaped to receive the first and second guide members respectively, and wherein the first and second guides are not shaped to receive the second and first guide members respectively. A biasing member biases the second member relative to the first member along the longitudinal axis. An indicating member is disposed between the first and second housing members.
