Abstract
An article for sequential dispensing of vapors, notably evaporable fragrances, comprises separated first and second liquids (). Liquid () issues first. Its evaporation may be assisted by a wick (). The simultaneous evaporation of the second liquid is prevented by an intermediate liquid phase (). As liquid () issues the liquid levels change and there comes a point at which the intermediate phase can no longer prevent the second liquid () from flowing past it, to the region from which it can be evaporated. Solids, especially gels, may be employed instead of liquids ().
