  • Patent number: 10206534
    Abstract: A system, device and method for the brewing of a capsule. The device comprises a first chamber portion and a second chamber portion movable with respect to each other to be moved between an open position and a closed position. The device further comprises a capsule handler arranged to enable insertion therein of the capsule and to position said capsule in a brewing position, wherein the capsule handler retains the capsule in the brewing position when the capsule handler is in a ready position. When the first chamber portion and the second chamber portion are moved with respect to each other from the closed position to the open position, the capsule can fall freely from the brewing position under the influence of gravity when the capsule handler is in an ejection position.

  • Patent number: 9027465
    Abstract: A holder and method for obtaining a holder, wherein the holder is provided with a first and a second wall part. The first and second wall part are interconnected such that therebetween at least a first storage space, at least a first fluid connection and at least a first seal removable through fluid pressure and defining an opening are formed. The at least first removable connection is communication with the first storage space and seals a communication to or from the at least first fluid connection. With the method for obtaining the holder, prior to forming the connection of the first and second wall parts, a lacquer is locally applied to one of the first and second wall parts, which after connection results in a controlled reduced adhesion for obtaining the at least first removable seal. Here in the proximity of the removable seal, an additional connection of the first wall part to the second wall part is provided.
