Abstract

L'invention concerne une capsule (1) comportant un corps de capsule (2) de préférence à symétrie de révolution qui comporte une paroi latérale (3) et un fond (4) formé notamment d'une seule pièce avec ladite paroi. Le corps de capsule est recouvert d'un couvercle (5) de façon à former une chambre (6) qui contient une substance (7) destinée à la préparation d'un aliment liquide. Au-dessus du fond (4) est maintenu un disque à éclatement (8) qui éclate à une pression interne dans la chambre. Selon l'invention, on peut libérer les orifices ménagés dans le disque de rupture, ce qui permet de commander le comportement de l'écoulement.
