Method for producing beverages
A relatively large quantity of a liquid is passed through a relatively small quantity of beverage-producing substance disposed in a pocket between two foils. Two conduits grasp the foils between them in endwise abutting sealed relationship, with the pocket within the conduits. One foil is weaker than the other, so as to be ruptured by the pressure of the liquid.
