Abstract
A hand-held, portable dispensing device (i.e. a wand) is described for dispensing a curtain spray pattern of liquid which includes an elongated tubular body having an open end and a closed end. The open end can be connected to a flexible hose or the like for supplying pressurized liquid to the tubular body which has a plurality of spaced openings along its length on one side. The spacing of the discharge openings is determined by the diameter of the openings, and the ratio of the total area of the openings to the inside diameter of the tubular body is in a defined range. The openings can be in a single line or in a plurality of rows, for example, An adjustable control valve and a quick connect coupler can also be included.
