Abstract

L'invention concerne une cartouche amovible (C) qui est conçue pour être reçue dans un dispositif pour la diffusion contrôlée d'un flux d'air parfumé qui comprend un boîtier (132, 146) qui loge un substrat (200) pour stocker une substance ou une composition parfumée, caractérisé en ce que le substrat est une tranche de substrat d'une seule pièce (200) constituée d'une céramique imprégnée. La tranche de substrat (200) a un noyau central à partir duquel s'étend une série de branches périphériques (BL, BT).
