1. A device for applying controlled doses of a flowable adhesive material to a surface, the device comprising:
a tubular body having a wall defining a cavity, the body having a first open end and an opposite second end having a dispensing orifice;
a flowable adhesive material in the cavity;
a plunger having an outer sleeve dimensioned for surrounding at least a section the body and having an inner pushing structure dimensioned for axial movement in the cavity; and
means for indexed positioning of the second end of the body and an inner end of the inner pushing structure of the plunger relative to each other to provide controlled doses of the flowable adhesive material such that the controlled doses of the flowable adhesive material may be applied to the surface when the plunger is moved toward the dispensing orifice, and
wherein the means for indexed positioning comprises a guide track and a guide pin that travels stepwise in the guide track, one of the guide track and the guide pin being located on an outer surface of the body and the other of the guide track and the guide pin being located on the outer sleeve of the plunger.
