Abstract

A flat, rectangular box 4 formed of cardboard contains a bag 18 of multi-layered foil material. A tube 24, which is disposed in the interior of the box in the transport condition of the package and can be removed from the box interior through an opening 10 which is closed by a tear-off strip, which is connected in liquid-tight manner to the bag 18 by a connecting piece. An outlet 36 provided at the free end of the tube is controlled by a pressure relief valve, which is provided in the tube and 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 outwards when the broad sides of the box are pressed together in order to empty the bag 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 12 of the box, which can be separated away from one of the broad sides, serves for interchangeably securing the container in the vending machine for the extraction of the fluid.
