AbstractA spray container or can which possesses a spray mechanism for finely atomizing fluids through the intermediary of a hydraulically-operating pump. Containers such as spray cans and spary bottles or flasks of the above-mentioned type generally known in commerce. Through the intermediary of mechanically actuatable pumps, in this instance there is sprayed a finely atomized fluid from a nozzle which is arranged on a housing of the container. The spary mechanism is inserted into a housing which is connectable with the supply container for the spray fluid or liquid through a close-fitted or frictional locking connection, and in which the spray mechanism incorporates an electromotively driven gear pump, and in which the suction line of the pump is conducted through an opening in the bottom of the housing into the supply container, the latter of which is equipped with a venting line, whereby the gear pump includes a delivery or pressure tube at its output end which is connected with a discharge nozzle.
