Abstract

L'invention concerne un couvercle muni d'un indicateur de changement pour une carafe filtrante. L'indicateur de changement comprend une tige filetée qui peut tourner par l'intermédiaire d'un processus de fermeture et/ou d'ouverture d'un élément de fermeture se présentant sous la forme d'un clapet. Un coulisseau se déplace sur la tige filetée, le nombre de processus de fermeture et/ou d'ouverture pouvant être déterminé à l'aide de la position de ce coulisseau. L'invention concerne en outre un couvercle pourvu d'un clapet qui est maintenu dans une position ouverte et dans une position fermée par un ressort de traction précontraint.
