Abstract: A beverage preparation capsule including front and back sheets that are bonded together along a top edge, first and second side edges, and a bottom edge. A region of bonding along the bottom edge may be releasable to allow escape of beverage from the capsule during beverage preparation. There may be a transverse seal that is interrupted by a gap that provides fluid communication between a beverage ingredient chamber located above said gap and a beverage outlet chamber located below said gap. A folded filter strip extending across the capsule includes a fold extending transversely below said transverse seal and front and back side panels extending upwardly through said transverse seal that are bonded to the front and back sheets of the capsule, respectively. The front and back side panels may not extend more than about 10 mm into said beverage ingredient chamber above said transverse seal.

Abstract: A beverage preparation apparatus for preparation of a beverage from a capsule in a clamp assembly (30). The clamp assembly has a first clamp member (31) and a second clamp member, where the inner surfaces of the first clamp member and the second clamp member form a clamp chamber (33) for substantially enclosing and supporting a capsule (10) during beverage preparation. The second clamp member comprises a rigid peripheral frame (32) having a central void and a resilient layer (37) extending across said central void. There is a piston (36) positioned in the central void and resiliently coupled to the peripheral frame (32) to allow limited resilient movement of the rigid peripheral frame (32) relative to the piston (36).
