Abstract
A dispenser which deters theft of packaged items includes an ejector. The ejector is resiliently biased to an extended position, and is selectively retracted to a retracted position. When so retracted, it can be released so that it can translate a static package into a dynamic state as quickly as possible to minimize the effect of drag and friction between the package being ejected and the package immediately behind it in a column of packages, as well as between the package and the portions of the housing which are initially contacted by the package. The first package is ejected in a short impulse so as to minimize a transfer of kinetic energy to a second package, thus minimizing the effect of static inertia of the second package on the first package.
