[ What is claimed is:] [1.]1. In an atomizer for dispensing a liquid active material, the combination of, a container for said liquid, an orifice plate having apertures therein, said plate being vibrated by a piezoelectric element, a capillary feed mechanism positioned to supply said liquid from said container to said orifice plate, said capillary feed mechanism comprising a highly porous and compliant wick and a wick holder arranged to hold said wick in a position such that it contacts the orifice plate to provide liquid to said orifice plate, the compliance of said wick being appropriate to cause negligible damping of said orifice plate.
