摘要

The dispenser for paste products comprises a cylindrical container (1) with an inner chamber (32) for a first product and an outer chamber (42) enclosing it. A driven feed piston (30,40) is movably installed in each chamber and separated from one another by a cylindrical driven drive spindle (21) which is in threaded engagement with one (40) of the pistons and interacts with the other piston (30) by friction. The second piston (30) is in engagement with a threaded spigot (13) which is fastened to the container as a separate component part.
