Abstract
A dispenser for dispensing jets of air laden with fragrance, the dispenser being characterized in that it includes a deformable flexible pouch of variable internal volume containing fragrance microcapsules, the pouch initially being substantially empty of air with the fragrance microcapsules intact, the fragrance microcapsules being broken the first time air enters into the pouch, in such a manner as to load the air in the pouch with fragrance, the pouch including an orifice through which the air penetrates into the pouch, and through which the fragrance-laden air leaves the pouch when the volume of the pouch is varied.
