Abstract A device (10) for dispensing volatile substances (24), such as fragrances, insect repellents, and the like, is comprised of a plastic, glass, or metal hollow body (12) which is essentially impermeable to a volatile liquid material (24), contained within the hollow body (12), and further constructed such that at least one open side (16) is bounded by a disc or slab (26) made of a silicone rubber, wherein the silicone rubber material is in contact with the liquid volatile substance (24), such as a fragrance or insect repellant, and wherein the liquid substance (24) is allowed to diffuse through the silicone rubber material to the surrounding environment.
A device for dispensing volatile substances which comprises; A. an open-ended hollow body (12) of a material which is substantially impermeable to said volatile substance; B. a liquid volatile substance (24) contained in the hollow of said body (12); C. a silicone rubber closure (26) mounted in the open end (16) of the hollow body (12) and in contact with the liquid volatile substance (24), said closure (26) being permeable to said substance (24) and D. a base (18) attached to the open end (16) of the hollow body (12), said base (18) including means (20) to allow circulation of air below the silicone rubber closure (26).
