Abstract:
An aerosol system for dispensing sprayable material in a desired spray pattern comprises an aerosol assembly and an outlet assembly. The outlet assembly comprises an actuator member, at least one flexible outlet member supported on the actuator member such that at least one pair of edges defined by the at least one flexible outlet member overlap, and a movable member supported on the actuator member to define an actuator assembly. The movable member is displaced such that the movable member acts on the at least one flexible outlet member to deform the at least one flexible outlet member to alter an effective cross-sectional area of at least a portion of a dispensing path to control fluid flow along the dispensing path and thereby cause the sprayable material to be dispensed in the desired spray pattern.
Abstract:
A method of dispensing sprayable material in a desired spray pattern using an actuator member, a resilient outlet member, and a movable member. The actuator member has a plurality of resilient finger projections. The resilient outlet member is arranged at least partly between the finger projections. The movable member is supported on the actuator member to form a dispensing path extending from the interior of the aerosol chamber to the exterior of the aerosol chamber through a valve assembly, the actuator member, and the outlet member. The movable member acts on the outlet member to deform the plurality of finger projections towards each other to alter an effective cross-sectional area of at least a portion of a dispensing path to control fluid flow along the dispensing path and thereby cause the sprayable material to be dispensed in the desired spray pattern.
