ABSTRACT OF THE DISCLOSURE A miniature type, rechargeable atomizing spray mechanism having a container for the liquid to be atomized, and further having a cap and axially aligned first and second pressure chambers, one of which depends within a receptacle while the other projects above the cap. A reciprocable spray head or actuator is arranged to cooperate with plural pistons, one each of which are telescopically arranged in said first and second pressure chamber. Upper and lower valve members are available to control the emission of spray of the liquid. The upper valve is maintained closed by a spring element, and the lower valve is opened by reciprocation of the actuator to permit withdrawal of the liquid from the container so that it may pass through a bore provided between the plural pistons and in the pressure chambers and be emitted as a spray from the spray nozzle at the spray head. Said first pressure chamber has advantageously at least one elevational rib axially formed within an annular recess formed on the inside peripheral wall thereof for providing a gap between the piston and the first pressure chamber means to thereby smoothly pump the liquid in the liquid container to the nozzle through the pistons telescoped within the respective pressure chambers and liquid passage in the actuator - 1 -
