Abstract

Un filtre pour faire du café (100) en vue de préparer l'équivalent d'une tasse de café filtre comporte un corps façonné (10) se présentant sous la forme d'un corps creux cylindrique (11) réalisé en un papier-filtre qui possède une rigidité propre et une résistance à la déformation suffisantes lorsqu'il est mouillé. Le corps façonné (10) présente une ouverture de remplissage (15) pour l'introduction de l'eau bouillante, et l'intérieur dudit corps (10) est divisé en une pluralité de chambres superposées (30, 130, 230). La chambre supérieure (30), qui reçoit l'eau bouillante, débouche dans l'ouverture de remplissage (15) destinée à l'eau. Une portion (40) de café moulu suffisante pour une tasse est déposée sur la cloison inférieure (120) dans la chambre centrale (130). Le café filtre s'écoule par la chambre inférieure (230). Pour préparer une tasse de café filtre, le filtre à café (100) est placé dans une tasse à café et de l'eau bouillante est versée par l'ouverture de remplissage (15) du corps façonné (10). Pendant que le café passe, le filtre (100) ne flotte pas à mesure que le niveau de café monte à l'intérieur de celui-ci.
