Abstract (en)
[origin: WO2008087553A1] The labyrinth capsule consists of a cup-shaped capsule (1), the capsule base of which is formed from a labyrinth plate (4) having a labyrinth structure and puncturing pins (14) on its upper side. A hole (10) with a central round stud (12) is located in the labyrinth plate center (5). A sealing film (7) is placed on the labyrinth plate (4) and is welded along its edge to the edge of the labyrinth plate (4). The capsule (1) is sealed on its upper edge (2) with a closure film, thereby closing in the filling. When liquid presses in through the closure film, the sealing film (7) is pressed against the labyrinth plate (4). The puncturing pins (14) puncture the sealing film (7). The liquid flows through the puncture holes and, thereafter, to the lower side of the labyrinth plate (4), to the labyrinth, and drains out between the labyrinth ridges (5). Finally, a laminar liquid stream is formed from the round stud (12) in the spout hole (10).
