CAPSULE MULTI-PIERCER

摘要

An extraction unit (1) has a piercing device (10) for piercing a capsule (20). The piercing device comprises a plurality of piercing elements (11a, 11b). Each element has a piercing extremity (12a, 12b) arranged to pierce the capsule in a piercing direction (10′), such as a direction (10′) generally parallel to an axis (12a′, 12b′) of the piercing elements (11a, 11b). The piercing extremities are arranged to form at corresponding locations (22′) in the capsule either a series of corresponding inlet openings (22′) or a series of corresponding outlet openings. The extremities (12a, 12b) are generally located on different virtual piercing planes (13a, 13b) generally perpendicular to the piercing direction (10′).
