Abstract of the Disclosure A powder dispenser suitable for use as a fire extinguisher and for dispensing particulated solids com- prising a container having flexible side walls and formed with an annular neck portion on which a dispensing head is mounted having an orifice terminating in a discharge nozzle. A first conduit is connected at its upper end to the orifice of the dispensing head and extends downwardly within the container such that the lower inlet end thereof is disposed at a position spaced from the base of the container. A second conduit is positioned in encircling relationship around the first conduit in substantially concentric relationship forming an annulus having its upper end disposed in communication with the upper end of the interior of the container and its lower end terminating at a position axially spaced upwardly from the inlet end of the first conduit at a controlled distance corres- ponding to about one-eighth to about one-half the diameter of the first conduit such that upon deflection of the side walls of the container such as by squeezing, a fluidi- zation of the powder adjacent to the inlet end of the first conduit is effected providing an optimum air to powder ratio which is discharged from the dispensing head in the form of a well defined substantially uniform dis- persion.
