A unit container for a treatment fluid comprises a sealed enclosure of which one wall section thereof is formed with at least one opening. The enclosure is pressuriseable to discharge its contents through the opening or openings, which is or are of sufficient diameter to enable the generation of a jet and/or discrete droplets of treatment fluid discharged therefrom. The one wall section is typically a flat section of the enclosure wall, and the enclosure is typically a blister pack, with the wall section at a planar base of the blister. However, the one wall section may be dome-shaped and formed with at least one opening in the top region of the dome. Containers of the invention may be provided in packages, for example in strip form or in planar arrays. Dispensing devices are described for discharging their contents in treatment.

1. 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.
