ABSTRACT:
A dispenser (1,1a) provides for filling a dosing chamber (15,15a) by gravity and then emptying it by closing an inlet valve (39,39a), by opening an outlet valve (40,40a) and by shortening the dosing chamber (15,15a) with the assistance of air flow through a discharge port (7,7a) and into a cup (80) which in one embodiment is assembled as part of the dispenser (1a) and which is removable so that its medium contents can be dispensed. Such a dispenser (1,1a) achieves a highly accurate dosing with simple handling and construction.
