Abstract
A volatile composition dispenser includes a housing having opposing first and second walls that are joined along their peripheries to one another. The first wall has an aperture and the second wall has a plurality of apertures. Within the housing, rests a volatile composition cartridge and a gap, which exists between the cartridge and a bottom surface of the housing, wherein said bottom surface is formed from a joinder of a base portion of one or both of the first and second walls, and wherein, upon activation, the exposure percentage of the dispenser is from about 40% to about 90%; wherein at least about 60% of the total surface area of the plurality of apertures results from individual apertures of said plurality that each have an area of at least 30 mm2 and an aspect ratio of at least about 1:2. Dispenser of a similar housing, cartridge, and gap when is activated by a user and thirty days after said activation, exhibits about 70% to 90% weight loss of said volatile composition of a partially exposed membrane of a fully exposed membrane.
