Abstract: Capsule (9) for use in a beverage preparation machine (1), said capsule comprising side (10), bottom (12) and top (11) walls defining a closed chamber, said chamber containing an ingredient, said capsule further comprising a beverage dispensing wall able to open for releasing a beverage prepared from said ingredient and said fluid, said capsule further comprising a pierceable plug (14) located adjacent to the inner side of the injection wall of the capsule, and made of a resilient material, said plug having a thickness between 0.5 mm and 10 mm, and said plug having shape and dimensions such as to be pierced through by the fluid injection element (20) when said capsule is functionally inserted within said machine, characterized in that said plug (14) is supported by a plug supporting member (16).

Abstract: The present invention concerns a capsule (12) for the preparation of a food or beverage by injection therein of a fluid under pressure, comprising a chamber containing a substance, a bottom pierceable membrane (23), and opening means (24) allowing the capsule to be opened by piercing the bottom membrane for allowing the beverage to flow out of the capsule, the opening means (24) comprising a surface with a multitude of piercing elements (25) which are configured to engage the bottom membrane (23) under the effect of the rise in pressure in the chamber, characterized in that said opening means (23) further comprises at least one safety piercing element (26) that is surrounded by a safety wall (27) such that the apex (28) of said safety piercing element is located within the vicinity of said safety wall (27).
