Abstract

L'invention concerne une capsule (1) pourvue d'un corps (2) présentant une paroi latérale (3) et un fond (4). La capsule est fermée par un couvercle (5) de manière à former une chambre (6) destinée à recevoir la substance (7). Au niveau du fond (4) de la capsule est disposée une ouverture de sortie (8) qui est isolée par rapport à l'atmosphère extérieure au moyen d'une membrane barrière (9). Au niveau de sa périphérie extérieure (10), la membrane barrière est raccordée solidement au fond de la capsule. La membrane barrière est en outre solidement raccordée à un élément d'appui (11) disposé de préférence au centre. Cette membrane barrière peut être déchirée sous l'effet d'une pression intérieure exercée dans la capsule, le comportement à la déchirure pouvant être mieux contrôlé par l'intermédiaire de l'élément d'appui.
