  • Patent number: 4871094
    Abstract: A dispenser for substances including solids, liquids, semi-solids, and gels including a forward member having a bore extending between its front and back opposite ends. The front end of the forward member consists of an application orifice. A rearward member is translateably movable with respect to the forward member and includes a plunger which is extendable through the back end of the forward member into the bore of the forward member. The plunger is slidable in the bore in response to movement of the forward section with respect to the rearward section. The substance, having been inserted into the bore, is then expelled from the application orifice in a precise and easily maneuverable manner. The dispensing means can be used with substances which are pre-packaged in capillary-type containers. The plunger can have different diametered sections which allow expulsion of the substance and then allow expulsion of the capillary-type container.
