Summary:Disclosed are devices for dispensing volatile materials such as fragrances into the atmosphere surrounding each such device. Release of volatile materials from a volatilization zone in such a device is promoted by the generation of heat via the non-combustive oxidation reaction of thermogenic materials held within a heating zone in the device. Both the volatilization zone and the heating zone are provided with hermetic sealing means which, prior to device activation, keep the contents of the volatilization and heating zones separate from each other and from the surrounding atmosphere. Such sealing means can be ruptured to expose the thermogenic materials to air to thereby initiate heat generation and to expose the volatilization zone to the surrounding atmosphere to thereby release the volatile materials therefrom. L'invention concerne des dispositifs de diffusion de matières volatiles, par exemple des parfums, dans l'atmosphère entourant chacun de ces dispositifs. La libération des matières volatiles d'une zone de volatilisation d'un dispositif de ce type est facilitée par la génération de chaleur via la réaction d'oxydation sans combustion de matières thermogéniques conservées dans une zone de chauffage du dispositif. La zone de volatilisation et la zone de chauffage sont toutes deux pourvues d'organes d'étanchéité hermétiques qui, avant l'activation du dispositif, maintiennent les contenus des zones de volatilisation et de chauffage séparés l'un de l'autre et de l'atmosphère environnante. Ces organes d'étanchéité peuvent se rompre de manière à exposer les matières thermogéniques à l'air afin de générer de la chaleur et d'exposer la zone de volatilisation à l'atmosphère environnante, et libérer ainsi les matières volatiles.
