Abstract

L'invention concerne un corps de capsule qui est conçu pour contenir un ou plusieurs ingrédients de boisson destinés à être utilisés dans une machine de préparation de boisson. Le corps de capsule comprend un corps de base ayant des parois latérales définissant une cavité pour recevoir le ou les ingrédients de boisson, un rebord de type bride s'étendant depuis les parois latérales, et un élément d'étanchéité conçu pour fournir un engagement étanche entre le corps de capsule et la machine de préparation de boisson. Les parois latérales comprennent une surface interne faisant face à la cavité définie par les parois latérales, et une surface externe faisant face à la machine de préparation de boisson en utilisation. L'élément d'étanchéité est positionné sur une surface du rebord de type bride qui s'étend depuis la surface interne des parois latérales.
