ABSTRACT:
A cylindrical container for viscous material has a first open base end of a first diameter and a spaced opposite closed base end with an opening therethrough of a second diameter smaller than the first diameter. A cylindrical plunger of a third diameter slightly smaller than the first diameter is coaxially slidably mounted in the container in a snug manner. The plunger has a closed plunger head perpendicular to its axis. A positioning device selectively positions the plunger and the container relative to each other at a plurality of different axial positions. The plunger, at each of the axial positions, forces a predetermined measured amount of the viscous material out of the opening of the container.
