Abstract
A dispensing device for use with a beneficial agent has a dispensing package, a dispenser disposed on an end portion of the dispensing package, and an actuator movably disposed along at least a portion of the package between a pre-dispensing state and a dispensing state. One arrangement also provides a beneficial agent dispenser having a dispensing port, an elongate portion and a plunger that is movably disposed relative to a tubular wall of the elongate portion during a dispensing stroke to partially penetrate a separable barrier and expel the beneficial agent through the dispensing port.
