Abstract

L'invention concerne une capsule (1) pour la préparation de boissons infusées ou instantanées dans une machine d'extraction comprenant un gobelet (2) fermé d'un côté par un couvercle (6) et du côté opposé par une base (3) destinée à être perforée par des moyens d'ouverture de la machine d'extraction pour l'injection d'un fluide sous pression. La base (3) est constituée d'un matériau plastique multicouche ayant une couche externe (51), une couche interne (53) et une couche intermédiaire (52) appropriée pour créer un joint étanche aux gaz. La capsule est caractérisée en ce que la base (3) comporte au moins une partie fragile (33) en forme de rainure (71, 73) qui s'étend dans la couche externe (51) et/ou dans la couche interne (53) sans atteindre la couche intermédiaire (52) de manière à obtenir une fragilisation dans la base (3) sans compromettre le joint étanche aux gaz.
