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.

A one-way package for storing fluid and from which the stored fluid may be dispensed in successive metered portions, said one-way package comprising: means defining a fluid-tight bag enclosing a fluid storage space; an extraction tube having an inlet end sealingly communicated through said bag to said fluid storage space and an outlet end disposed externally of said fluid storage space; a flat package box surrounding said bag, said flat package box being made of relatively stiff material compared with said bag and being constructed and arranged for also containing said tube, for storage; said tube including an extraction duct extending therealong, a longitudinally extending portion of which provides a metering chamber normally in communication with said inlet end of said tube; said tube further including a pressure relief valve provided for said extraction duct near said outlet end of said tube for normally closing said outlet end of said tube; means provided between said inlet end of said tube and said metering chamber constructed and arranged for permitting interruption in communication between said metering chamber and said inlet end of said tube; means for squeezing the bag; said flat package box including two relatively broad opposed wall means which are perimetrically joined to one another by relatively narrow wall means, these relatively narrow wall means including a total of one, outwardly-bowed fold line means extending perimetrically of the flat package box on the relatively narrow wall means approximately midway between the two relatively broad opposed wall means, whereby said bag may be emptied in dispensing fluid from said fluid storage space into said duct by actuating said means for squeezing the bag by pressing one of said two relatively broad opposed wall means towards the other of said two relatively broad opposed wall means while permitting said relatively narrow wall means to fold on itself along said fold line means.
