PURPOSE: To provide a dispenser in which a cylinder tube is exchangeable and piston or plunger is reapplicable after they have been used. CONSTITUTION: The dispenser has an outer cylinder tube 12 having a small opening 25, a lower part 18 and a closed cap 14, a freely insertable plunger 20, a piston head 22 as a separated member separated from the plunger 20, and a sealing rim 30 that prevents leakage of the flowable materials 34 from a gap between the piston head 22 and the inner surface of the cylinder tube 12. Keeping the cylinder tube 12 free from germs, the plunger 20 and the cylinder tube 12 with flowable materials therein are prepacked as separate units. |
