• a tubular body having a wall defining a cavity suitable for holding the flowable material, the body having a first open end and an opposite second end having a dispensing orifice;
• 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 material when the plunger is moved toward the dispensing orifice,
• 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 the body and the other of the guide track and the guide pin being located on the outer sleeve of the plunger.

A refill for a device for dispensing controlled doses of a flowable material, the device including a plunger having an outer sleeve with a guide track comprising throughholes in the outer sleeve, the refill 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, the body having an inwardly movable guide pin attached to an outer surface of the body;
• and
• a flowable material in the cavity,
• wherein the guide pin is dimensioned to be received in the throughholes of the guide track.
