Abstract
A dispensing device as well as a dispensing head and use thereof are proposed. Through depression of the dispensing head, an associated dispensing valve is opened and the product to be delivered can escape or be dispensed through an outlet space and via a downstream outlet valve. In order to prevent or at least minimize subsequent dripping or foaming, the volume of the outlet space is initially reduced upon actuation of the dispensing head and enlarged again upon completion of actuation, particularly after closing of the dispensing valve, whereby the product is suctioned away from the outlet or outlet valve back into the outlet space.
