- 9 - ABSTRACT ANTI-LEAKAGE STRUCURE FOR A LIQUID ATOMISER Leakage of liquid from a container having an atomiser of the type including a cylinder piston moveably mounted within a ring body and defining annular air gap therebetween is prevented by providing the upper end of the ring body with an inwardly directed annular flange disposed in sealing and sliding engagement around the piston to prevent escape of fluid from the air gap due to inadvertent movement of the piston. The piston includes either a stepped diameter configuration or a plurality of circumferentially spaced longitudinal grooves which, when encountered by the flange after the piston has been intentionally moved a predetermined distance, permits air to flow through the air gap for dispensing liquid from the atomiser.
