Abstract: The preparation system has a capsule 11 which is provided with a conical side wall 13, a first end 13a of which has a larger outer diameter than the second end 13b. The capsule 11 is provided at the first end 13a with an outwardly projecting flange 15 to which a foil 19 is attached which foil closes the capsule. The preparation device 1 has a pressure cylinder 3 which is slid over the capsule 11 and presses the flange 15 against a counter plate 5. The pressure cylinder has to be liquid-tight in contact with the capsule. The outer diameter of the first end 13a of the side wall 13 of the capsule being larger than the inner diameter of the pressure cylinder 3. When the pressure cylinder is slid over the capsule, the capsule will compress in the axial direction, such that the deformed part of the side wall 13 forms a liquid-tight seal between the capsule 11 and the pressure cylinder 3.

Abstract: A hanging system has a hanging rail 3 and a number of mounting clips 1 for mounting the hanging rail 3 against a soft wall. Each mounting clip is formed from a flat plate 5 and is provided with a rear side 7 with which the mounting clip is in contact with the wall during use. Each mounting clip is provided with cams 11 and 13 protruding at the front 9. The hanging rail 3 is an extrusion profile of which a part 3a has a cross-section that is C-shaped and is provided with two spaced apart edge parts 15 and 17. The top edge part 15 hooks behind the top cam 11 and the bottom edge part 17 is clicked over the bottom cam 13. Each clip is furthermore provided with two bent nails 19 which protrude at the rear side 7 and which can be pressed into the soft wall, wherein parts 9b of the front form pressure surfaces.

Abstract: A container 1 containing ground coffee 5 is provided with a side wall 7 and two end walls 9 and 11 which are made of sheets of filtering material. A rigid plastic foil 13, 15 made of biologically degradable material is sealed to the two end walls. This foil carries a multitude of local weakenings which are formed by recesses formed by means of a CO2 laser. Around each weakening is situated a thickening and/or strengthening of the foil. The foils are sealed with the side carrying the weakenings to the sheets of filtering material. Before this container can be used in an apparatus that is suitable for cooperation with cups, the container is first to be placed into an auxiliary container 3 open at both ends. This auxiliary container is provided with a rigid tapered side wall 17 so as to avoid liquid easily flowing to draining holes in the apparatus via the porous side wall along the outside of the container.
