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