Abstract

L'invention concerne une unité de conditionnement pour des parties végétales, notamment du thé, destinée à la préparation d'une boisson infusée. L'unité de conditionnement comprend : un godet imperméable à l'eau pourvu d'au moins un orifice de sortie ; au moins une couche filtrante perméable à l'eau, laquelle est disposée dans la zone de l'orifice de sortie ; une couche de protection imperméable à l'eau. La couche de protection isole au moins la couche filtrante de l'environnement de l'unité de conditionnement et la couche de protection repose sur la couche filtrante sur le côté opposé au contenu dans une zone donnée. La couche filtrante ainsi que la couche de protection sont reliées au godet, au moins l'une des couches directement.
