Abstract
Atomizer for liquids is mounted on a compressible container for the liquid so as to define an atomizing chamber in the neck of the container, which has an outlet nozzle and is connected through a depending tube to the lower part of the container and through a short duct to its upper part. The container is also connected to the open air through inlets controlled by non-return valves preventing the escape of fluid therethrough. When the container is compressed liquid flows into the atomization chamber through the tube, and air flows into it through the duct, so that a spray is dispensed through the nozzle. When the container is permitted to expand air is sucked in through the air inlets, which are larger in section than the nozzle. In one embodiment filters are provided to filter air drawn in through the air inlets.
