A cap (1) for a container (2) housing a consumer product, comprising a device (7, 11) capable of diffusing a volatile substance inside said container, said device being formed of a cap liner element (8, 12) carrying the volatile substance and of a barrier element (10, 14) lodged between the cap liner element and the interior of the container, wherein said barrier element is formed of a membrane permeable to the vapors of the volatile substance and impermeable to the consumer product, so as to enable molecular diffusion of the volatile substance's vapors inside the closed container, so as to enable molecular diffusion of the volatile substance's vapors into the headspace above the consumer product when the container is closed.
L'invention concerne la capsule (1) d'un récipient (2) renfermant un produit destiné au consommateur, qui comprend un dispositif (7, 11) pouvant diffuser une substance volatile à l'intérieur dudit récipient. Ledit dispositif est constitué d'un élément joint de bouchon (8, 12) portant la substance volatile et d'un élément barrière (10, 14) placé entre l'élément joint de capsule et l'intérieur du récipient. Ledit élément barrière est constitué d'une membrane perméable aux vapeurs de la substance volatile et imperméable au produit destiné au consommateur, la diffusion moléculaire des vapeurs de la substance volatile pouvant ainsi se faire à l'intérieur du récipient fermé et à l'intérieur de l'espace libre se trouvant au-dessus du produit destiné au consommateur lorsque le récipient est fermé.
