Abstract: The volatile substance diffuser comprises a support (1) impregnated with the volatile substances, wherein at least one portion of the volatile substances is contained in at least first microcapsules (2) and second microcapsules (3) comprising a core (10) and a coating (11), the diffusion times of the first and second microcapsules (2, 3) being different to each other. It enables the diffusion time of the volatile substances to be increased.

Abstract: A volatile substance evaporator device comprising a heat source and a refill including said volatile substances, wherein the heat source is a flame that heats a transmission element which heats said refill for evaporating the volatile substances. The result thereof is that the volatile substances evaporate properly without the need to use batteries or a similar power source, simply by the use of a flame, for example in the form of a candle, the financial cost thereof being very low.

Abstract: A volatile substance evaporation element including a rod impregnated with volatile substances, the rod being made of sintered wood. The porosity of the rod varies between its core and its surface, the porosity of said rod being lower on its surface than in its core, making it possible to increase the capacity of the core of the evaporation element to act as a receptacle for volatile substances.

Abstract: A device including a receptacle that defines a neck. A liquid that impregnates diffusion means is housed inside the receptacle. The diffusion means includes a flexible band and a rigid band in contact with each other, the flexible band being in contact with the liquid inside the receptacle. The device also includes an inner closing element that fits tightly inside the neck and a regulation element complementary to the inner closing element. The rigid band is associated with the regulation element, the position of which determines the surface of the rigid band arranged on the outside of the receptacle. The device facilitates accurate regulation of the exposed surface of the rigid band, thereby regulating the intensity of the perfume in a room.
