A device is provided for dispensing a mixture of propellant and product (e.g. medicament) from a pressurized aerosol container (3). The device has a housing (1) receiving the container (3), a cover (7) and an actuator lever (10) all pivotally connected to one another. The axes of pivoting are so arranged that moving the cover (7) from a closed position to an open position puts the device in a “primed”condition in which squeezing the housing (1) and actuator lever (10) together displaces the container (3) with respect to the housing (1) and thereby opens the outlet valve (4) of the container (3) to dispense mixture from the container.

A device for dispensing a mixture of propellant and product from a pressurized aerosol container having an outlet valve, comprising a housing receiving, or adapted to receive, a pressurized aerosol container, the housing having an outlet spout near one end thereof; a cover; cooperating pivot means on the cover and on the housing near the other end thereof, which provide for pivotal movement between the cover and the housing about a first axis, the cover being pivotal from a closed position in which it encloses the outlet spout to an open position in which the outlet spout is exposed; an actuator lever having a portion disposed to be engagable with the container to exert an axial force thereon; cooperating pivot means on the cover and the lever which provide for pivotal movement between the cover and the lever, the lever being pivotally closable onto a portion of the housing not covered by the cover, pivotal movement between the cover and lever being about a second axis which is parallel to said first axis and is spaced therefrom, whereby movement of the cover from its closed position to its open position shifts the position of said first axis with respect to said second axis, said shift being such as to bring said container-engaging portion of said lever into engagement with said cover so that when the lever is closed on the housing it exerts a force on the container to displace the container with respect to the housing and to open the outlet valve of the container to dispense said mixture from the container through the outlet spout.
