ABSTRACT A flat, rectangular box made of cardboard contains a bag of multi- layered foil material. A tube, which is disposed in the inside of the box when the package is in the transport condition and can be removed from this through an opening which is closed by a tear-off strip, is connected in a fluid-tight manner with the bag by a connecting piece. An outlet provided at the free end of the tube is controlled by a pressure relief valve provided in the tube and which opens in the direction of the outlet. The walls of the narrow sides of the box each have a longitudinal fold along which these walls can fold outward when the broad sides of the box are pressed together in order to empty the bag which is filled with a fluid, e.g. coffee extract. The one-way package is particularly suitable for use in a beverage vending machine in place of the storage containers employed until now. A suspension flap of the box, which can be separated away from one of the broad sides, is used for interchangeably securing the container in the automatic machine for the extraction of the fluid.
