Abstract: A preparation system includes a cup or other vessel within which is fitted a liner. The liner and cup are spaced from one another and at least the upper portion of the liner is sealed to the cup to form an enclosed cavity within which a preparation component may be dispensed. The liner is foraminous, formed either of perforated material or material which is inherently foraminous. Upon introduction of a liquid or other substance into the liner, the substance contacts the dispensed material to form a desired composition. The preparation system may be provided as separate components to a food or drug manufacturer, for example, who dispenses into the cavity one or more components to be stored therein upon fitting the liner to the cup.
