Abstract
An aerosol dispenser of the hand-held type, comprising a can which contains a flexible, collapsible bag having the substance to be discharged. A valve on the can communicates with the bag to effect the discharge. In the can a spring engages a wall portion of the bag, tending to collapse the same, and there are manually operable means including a finger piece for varying the force applied by the spring to the bag as the contents of the latter are gradually depleted whereby the rate of discharge of the spray can be maintained more nearly constant regardless of the quantity of substance occupying the bag at any particular time.
