Long service life scent dispersing mat apparatus
US-7498072-B2Abstract
A long life scent dispersing mat apparatus uses an outer housing with apertures appointed to disperse a scent or fragrance. The fragrance is provided in a fragrant body which is a springy spongy rubber or polymeric sponge soaked with essential oils that have high vapor pressure at ambient temperatures. The fragrant body is inserted into an inner pouch which has small apertures and the stagnant air within the inner pouch attains saturation of fragrance vapor, thereby stopping further evaporation of the essential oils. When the scent-dispersing mat is stepped on, the inner pouch releases the saturated fragrant vapor into the interior of the outer housing and it is released to room air through apertures provided in the outer housing. When force on the mat is released, the fragrant body recovers its original shape and the inner pouch draws fresh make up air and essential oils volatilize until saturation is reached.
