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.

Indicating device with warning dosage indicator

A system of medicament dispensers includes a plurality of dispenser housings each having a unique first indicia and a plurality of containers each having a unique second indicia. The unique second indicia of each of the containers corresponds to one of the unique first indicia of a corresponding one of the dispenser housings. Methods for associating various containers and dispensers is also provided.

Dispensing device

An 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.

Dose indicating device

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.

A method for displaying dosage indicia includes engaging a dispenser housing with a container in an engaged position, moving the container relative to the dispenser housing along a longitudinal axis while the container and the dispenser housing are in the engaged position, moving a valve between a closed position and an open position in response to moving the container relative to the dispenser housing and thereby dispensing metered dosages of substance when the valve is moved to the open position, moving the container relative to the dispenser housing to a disengaged position, moving an indicating portion with the container as the container is moved relative to the dispenser housing between the engaged and disengaged positions, and moving the indicator member relative to the container along the longitudinal axis while the container is in the engaged position.

Method for displaying dosage indicia

An indicating device suitable for indicating a number of metered dosages of a substance that have been dispensed from or remain in a container. The indicating device includes at least one primary indicator member having primary dosage indicia, configured as numeric indicia, and a second indicator member having secondaiy dosage indicia, configured with at least two different colors. The primary and secondary indicator members are coaxially mounted. In one embodiment, a device for dispensing dosages of the substance also includes a dispenser housing and a container.

A dispenser includes a dispenser housing, an indicating device connected to the dispenser housing and a container removably engaged with the dispenser housing. A connector maintains a connection between the container and the dispenser housing as the container is moved between an engaged position and a disengaged position relative to the dispenser housing.

A dispenser includes a dispenser housing, a key device adapted to be mounted to a container and an indicating device. The key device is moveable between an engaged position wherein it is engaged with the indicating device and a disengaged position wherein it is disengaged from the indicating device. In other aspects, a resilient, flexible cap is fixedly secured to the dispenser housing and covers the container and prevents the valve stem from being disengaged from the dispenser housing. In another aspect, a dispenser housing has at least one guide and a connector has at least one arm having a catch portion. The arm is disposed through the at least one guide with the catch portion engaged with the guide such that the valve stem is prevented from being disengaged from the dispenser housing. In yet another aspect, a catch portion engages a ferrule portion of the container such the valve stem is prevented from being disengaged from the dispenser housing.

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.

An indicating device includes an indicating portion and an actuator portion. At least a part of the indicating portion is moveable with a container between engaged and disengaged positions relative to a dispenser housing. The indicating portion includes at least one indicator member. The container is moveable relative to the at least one indicator member along the longitudinal axis when the container is in the engaged position.
