Comprises a vessel (1) that houses the active liquid substance to be diffused, such as a fragrance, insecticide or other, through a breathable membrane (2) that closes the vessel (1) and comprises a porous part (3) placed near and parallel to the breathable membrane (2) in order to prevent the deformation of the membrane (2) when a vacuum is generated as the vessel (1) is emptied. The porous part (3) has a number of openings (4) through which passes the liquid to ensure its contact with the membrane (2) at all times for a homogenous evaporation and it occupies part of the volume of the vessel (1), absorbing the active substances, the non-volatile substances remaining in said porous part (3) after the vessel (1) has no more volatile components.
Container of active substances of the type comprising a vessel (1) that houses the active liquid substance to be diffused, such as a fragrance, insecticide or other, through a breathable membrane (2) that closes the vessel (1) and allows passage of the volatile components in a gaseous state, characterised in that it comprises a porous part (3) placed near and parallel to the breathable membrane (2) in order to prevent the deformation of the membrane (2) when a vacuum is generated as the vessel (1) is emptied.
