ABSTRACT:
A dispenser for dispensing a paste-type material includes: a container charged with a paste-type material and provided at its one end with an extrusion tip, the container being collapsible in the longitudinal direction until the internal volume thereof is almost completely nullified; a cylindrical body opened at its both ends and having a diameter such that the container charged with the paste-type material is received in the cylindrical body; a piston sized to be insertable into the cylindrical body; and an extruder having a receiving portion for receiving the cylindrical body and having an operating portion. The operating portion is operable to cause a predetermined amount of advance of the piston into the cylindrical body received in the receiving portion so as to collapse the container in the longitudinal direction, thereby extruding a predetermined amount of the paste-type material from the extrusion tip of the container upon each operation of the operating portion.
