ABSTRACT:
An arrangement has a hand-operated piston pump mountable on a neck of a bottle, and having a first portion outwardly embracing the neck and a second portion inwardly extending into the neck of the bottle. The first portion of the piston pump overlaps the neck over at least a part of its height and is supported by the same. The second portion is formed as a ring-shaped collar. For sealingly connecting the second portion to the neck of the bottle, there is provided as a rubber stopper located between the outer surface of the second portion of the piston pump and the inner surface of the neck of the bottle. The second portion may be provided with an inner thread which can mesh with an outer thread of the neck serving for screwing on a threaded cap. A member is further provided for detachably connecting a drink container to the arrangement so that the liquid withdrawing from the bottle travels directly into the container. The piston pump is a compressed air-operated pump and has an interruptable system of channels provided with an air inlet valve and an air outlet valve. The air inlet valve is formed on a piston of the piston pump, and the air outlet valve is formed on the second piston of the latter.
