Abstract

L'invention concerne une capsule (1) pourvue d'un corps (2), de préférence à symétrie de révolution, présentant au moins une paroi latérale (3) et un fond (4), ainsi qu'un couvercle (5) recouvrant le corps (2), servant à former au moins une chambre (6). Afin de guider un liquide à travers la chambre (6), le couvercle (5) forme un côté entrée et le fond (4) un côté sortie pourvu d'une ouverture d'évacuation (8). Au-dessus du fond (4), un récipient interne (9) séparé, recouvrant l'ouverture d'évacuation (8) et pouvant être traversé par le liquide, est maintenu dans la capsule (1) et contient une substance (7) servant à la préparation d'un produit alimentaire liquide. Le fond (4) et le récipient interne (9) présentent respectivement une surface d'étanchéité correspondant l'une avec l'autre (13, 14). En présence d'une pression hydraulique dans le récipient interne (9), les deux surfaces d'étanchéité (13, 14) peuvent être plaquées l'une contre l'autre.
