A 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.

A spray container including a spray mechanism for finely atomizing fluids through the intermediary of a hydraulically-operating pump; a housing for receiving said spray mechanism; a supply container for the spray fluid being connected with said housing by a locking closure, said spray mechanism including a gear pump, an electric motor for driving said pump, said pump having a suction line conducted through an opening in the bottom of the housing into the supply container, said container having a second opening in the bottom thereof for the through passage of an air conduit which is operatively connected with a motor switch for a motor of the spray mechanism, said opening having a cross section of about 2 to 5 mm, said container having a venting line, and said gear pump including a pressure line at the discharge end of the pump; and a fluid discharge nozzle being connected with said pressure line. A spray container as claimed in claim 1, wherein said venting line has an outlet which is closable by a ball subjected to the biasing action of a spring, whereby a vacuum generated in the supply container upon the withdrawal of fluid overcomes the biasing force of said spring force to cause the ball to move away from the venting line outlet.
