seal-backed capsule and capsule-based food preparation system

摘要

The present invention relates to a capsule (1) having at least one first container-like constructional element (2) and a second cap-shaped constructional element (3) provided to contain an individual portion. of said edible substance, said second constructional element (3) having a passageway wall (4) surrounded by at least most of its perimeter with a region of weakened material (41), and further having a region (6) adapted to provide seating for a sealing member (14) of an extraction device (10), and thereby a better seal of the upstream pressurized flow within said extraction device. The present invention further relates to an edible product preparation system including a capsule (1), an edible product preparation preparation apparatus comprising at least one extraction device (10) having a sealing member (14) adapted in order to seal the pressurized flow upstream of said capsule (1) to a region adjacent to the injection means (13) of said extraction device (10).
