An indicating device suitable for indicating the number of metered dosages that have been dispensed from or remain in a container including a base member, a cap member moveably connected to the base member, an indicator member rotatably mounted to one of the cap member and base member and a drive member. The indicator member comprises a first stop member, and the drive member comprises a second stop member. The first stop member engages the second stop member as the indicator is moved to the final position. The engagement between the first and second stop members prevents the drive member from being rotated about the second axis. In another preferred embodiment, an inhalation device for dispensing metered dosages of medicaments from a container includes a container having a predetermined number of metered doses and the indicating device. A method for indicating the number of metered dosages of medicaments dispensed from or remaining in the container is also provided.

Indicating device for aerosol container

An indicating device suitable for indicating the number of metered dosages that have been dispensed from or remain in a container including 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 between a first position and a second position a predetermined number of axial movements. An indicator member is rotatably mounted to the cap member. A first lock member disposed on the base member, and a second lock member is disposed on one of the indicator member and the cap member. The first and second lock members are engaged after the predetermined number of axial movements of the cap member relative to the base member, wherein the first and second lock members maintain the cap member and the base member in one of the first position and the second position when engaged. In another aspect, a preferred embodiment of a method for indicating the number of metered dosages of medicaments dispensed from or remaining in a container is provided.

Indicating device

An indicating device for indicating the number of metered doses of medicaments that have been dispensed from or remain in a container having a valve stem extending longitudinally therefrom and moveable between an open and closed position. The indicating device includes a base member adapted to be mounted to the container, a cap member moveably connected to the base member, an indicator member rotatably mounted to the cap member and an indicating mechanism adapted to rotate the counter member an incremental amount upon a predetermined number of axial movements of the cap member relative to the base member. A preferred embodiment of the indicating device includes a ratchet wheel, a drive member selectively engaging the indicating member, a pawl selectively engaging the ratchet wheel, and a non-return member adapted to selectively engage the ratchet wheel so as to maintain a unidirectional rotation of the ratchet wheel. A method for indicating the number of metered doses dispensed from or remaining in the container comprises moving the cap member toward and away from the base member, engaging the ratchet wheel with the pawl and engaging the indicating member with the drive member. A method of assembling an inhalation device including an indicating device is also provided.
