Abstract
A dispenser for viscous material, such as shoe polish, comprising a substantially cylindrical reservoir having near one reservoir end a filling discharge passage terminating in a distribution channel extending through a porous applicator. At least a part of the dispenser wall is deformable for pressing the filling out of the reservoir through the filling discharge passage into the distribution channel. The dispenser is characterized in that at the other end of the reservoir (16,24), there is provided a follower piston (6,28) which, while confining the filling at the discharge end of the reservoir, under the influence of a force exerted axially on the piston body (6,24), is movable stepwise in the direction of the filling discharge passage (9,29). The dispenser is further provided with pumping means operative upon deformation of the deformable portion (3,34) of the dispenser wall (2,25), which portion is resilient.
