Abstract
Described is a hollow container comprising a shell which is at least partially porous, containing an entrapped volatile substance and a process for dispensing the volatile substance at a visibly detectable rate, continuously or discontinuously, for discrete periods of time at a steady state, the volatile composition being in the alternative, a perfume composition, a deodorant composition, an air freshener composition, an insecticide composition, a herbicide composition, an odor masking composition, a pheremone composition, an animal repellent composition, or an insect repellent composition. The said container containing the entrapped volatile substance ceases to operate, discretely, when said container is placed in an outer air-tight container. The structure consisting of the outer container and the inner container is also a part of our invention.
