Abstract
A dispenser is disclosed which is made up of two telescoping sections. One section holds at least one volume of a substance to be discharged. Telescoping motion of the sections compresses the substance to be discharged to force it through a passage in the section not holding the substance volume to be discharged therefrom. Motion between the section is limited to ensure precise metering of a charge to be dispersed.
