Abstract

Cette invention concerne un extracteur capable d'extraire des composants de thé à partir d'eau chaude même si la quantité d'eau chaude est petite et que le niveau d'eau est abaissé pratiquement au niveau d'une plaque de base. Cet extracteur comprend un filtre comprenant une paroi latérale cylindrique et un piston assemblé au filtre, lequel extracteur se caractérise en ce que la plaque de base du filtre est imperméable au liquide, en ce que la paroi latérale du filtre comprenant une partie inférieure formant une partie de jonction avec la plaque de base est perméable au liquide et en ce que le piston est formé d'un corps de piston en forme de U inversé et d'une tige de piston rattachée à la partie centrale du corps de piston.
