ABSTRACT:
A dispenser of products having a varying degree of viscosity includes a longitudinal and hollow body of circular cross-section, upon which there is mounted a funnel. The hollow body contains in a rear part thereof a piston which is arranged to push forward an assembly of movable elements including a cross-piece, a piston, a sleeve and a resilient split ring, so as to expel a product dose through a cone formed with holes and loosely lined in the interior thereof with an elastic membrane. The movable elements are returned to their initial position by the force of a spring. The cone is extended by a pouring spout, which in turn carries a tube provided with a distributor cone.
