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 CO 2 laser. Around each weakening is situated a thickneing 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. |
