Abstract:
A method for delivery of a small amount of a treatment liquid to a target site, comprisinga. confining the liquid in a sealed and pressurizable enclosure, forming a unit container, the enclosure having at least one opening in a wall section thereof, said opening having a minimum diameter of at least 10 micrometers and being arranged to enable generation of a jet and/or droplets of the liquid discharged therefrom, the jet and/or droplets having a diameter no smaller than 20 micrometer, b. positioning and targeting the enclosure adjacent the target site such that there is a spacing between the opening and the target site, c. pressurizing the enclosure to discharge substantially all of its content through the opening in the form of a jet and/or droplets, the jet and/or droplets having a diameter no smaller than 20 micrometers and sufficient linear momentum to traverse the spacing both from above and horizontally or vertically upwards for impact on the target site.
