Abstract

A push-button dispenser for atomising a fluent active agent by means of a propellant gas 46 accommodated underpressure in a reservoir 43 placed inside a container containing the active agent and carried by a mounting obturating the container, said mounting containing a high pressure obturator 15 for the propellant reservoir and low pressure obturators 4 controlling the passage of the active agent to a nozzle 9 in the push button and of air towards the interior of the container, the push button having a tubular stem 7 accommodating passages 21 and 17 for the active agent and propellent to the nozzle which stem is mounted slidingly in said mounting and controls the said obturators, is characterised in that the mounting comprises a central body 2 having a central 'bore 6 which opens into a recess 13 facing the propellant reservoir, there being an annular shoulder 14 projecting into said bore against which the gasket 15 constituting the high pressure obturator is held by fastening means 16. Many embodiments of dispensers in accordance with the invention are described and illustrated, wherein the propellent path is opened before and remains open after the active agent path, ensuring clearing of the nozzle jet wherein the opening of the active agent path precedes the opening of the propellant path, ensuring economical use of propellent and wherein the opening of the propellent path precedes and overlaps the opening of the active agent path.
