Cartridge for Beverage Making A cartridge of cup like shape having a substantially impervious frusta-conical wall provided with a first circumferential seal adjacent the open mouth of the cup and a second circumferential seal spaced toward the bottom of the cup. The bottom is perforated and is sealed by a strippable foil. The cartridge contains a preselected amount of material (say ground coffee) that fills the receptacle to a selected level. Preferably a plurality of such receptacles are packaged as telescoped stack of cartridges with a first receptacle telescoped within a second receptacle so that the second circumferential seal on the first cartridge is received in the first circumferential seal of the second receptacle thereby to seal the material in the second receptacle. |
