Abstract: A refill for a liquid air freshener or insecticidal device comprising a cartridge containing a volatile liquid composition to be evaporated and a porous pad positioned, in use, beneath a lower face of the cartridge to receive the liquid composition as it is slowly released from the cartridge; wherein the porous pad is a part of a sheet of material which is folded to at least partially surround the cartridge.

Abstract: In an apparatus for dispensing a volatile substance from a main reservoir, a second reservoir is provided which contains an additional quantity of the volatile substance. The substance is dispensed from the second reservoir during a delay period in which it cannot be dispensed from the main reservoir.
