Fragrance diffuser, particularly for small spaces, and associated production process

A method for manufacturing fragrance diffusers, comprising a deformable main body, a separator film and a membrane, further comprising:

• a first step of deforming said main body in order to form a containment chamber and an expansion seat which are open respectively on a rear face of said main body;
• a second step of piercing said separator film in order to obtain at least one through opening;
• a third step of filling said containment chamber with a fluid;
• a fourth step of juxtaposing a first face of said separator film on said rear face so as to make said at least one opening match up at the open portion of said expansion seat;
• a fifth step of adhesion of said separator film on said rear face along at least one first closed track and one second closed track for the hermetic separation respectively of said containment chamber from said expansion seat;
• a sixth step of juxtaposing said membrane on a second face, which is opposite said first face, of said separator film in contact with said at least one opening;
• a seventh step of adhesion of said membrane to said separator film.
