Abstract

A dispenser for discharging media, comprising: a dispenser base; a discharge deliverer for forcing the media out of the dispenser; an actuator including a discharge actuator for activating the discharge deliverer between a rest position and an actuated end position remote from the rest position; an outlet duct for the medium; a medium outlet connected to the outlet duct for discharging the media out of the dispenser; a media reservoir bounding a reservoir space and including a reservoir closure for closing the reservoir space; each of the dispenser base, discharge deliverer, actuator, outlet duct, medium outlet and media reservoir forming constituent elements of a preassembled assembly; the assembly having a filling duct for filling a filling medium from outside the dispenser into the reservoir space, the filling duct communicating with the reservoir space as the media reservoir is preassembled with the discharge deliverer; and, a bounding wall projecting toward the reservoir space close to the media reservoir, the filling duct communicating between opposite sides of the bounding wall.
