Abstract: A dispenser for conveniently dispensing multiple transdermal/transmucosal drug-containing patches from a single container. The dispenser has an inner cartridge defined by walls made of an impermeable material, wherein the inner cartridge is hermetically sealed during storage. In another aspect, the dispenser incorporates a child-resistant mechanism.

Abstract: There is provided a nonwoven electret fiber filter formed with a nonwoven web of electret fibers needle-punched to an open scrim support. The scrim support material has individual discrete open areas with an average cross-sectional area as viewed from the plane of the filter media of at least 0.25 mm.sup.2, preferably 1.0 mm.sup.2, and a pressure drop across the scrim support, without the filter web, of less than 1.5 mm H.sub.2 O measured at 98.4 meters/min gaseous face velocity. The resulting filter has enhanced lifetimes, a low pressure drop and high filtration efficiencies.
