Abstract
A delivery device having a reservoir of variable volume having an outlet through which an included vehicle can be expressed in a liquid form as the volume of the reservoir is actively reduced. There is a tube providing a conduit to the outlet from the reservoir of such length and cross-section as to favor active release over passive release which has the effect of enabling a more positive control of the dispensing of the vehicle. Such a device has diverse applications.
