Abstract
A hollow-needle assembly is part of a transfer apparatus that serves for transferring a liquid between a storage container and a further use container. The hollow-needle assembly has a hollow needle having a pointed needle end. A liquid duct for transporting liquid through the hollow needle and out of the latter leads out via at least one liquid-duct opening in the region of the free needle end. An aeration gas duct that likewise leads out via a gas-duct opening in the region of the free needle end serves for transporting gas through the hollow-needle assembly. Duct paths of the at least one liquid duct and of the at least one aeration gas duct extend separately from one another. The ducts lead out adjacently to one another axially along the hollow needle and in a manner offset from one another in the circumferential direction. A needle separating edge that extends in the longitudinal direction of the hollow needle extends between in each case one liquid-duct opening and an adjacent gas-duct opening in the circumferential direction. This results in reliable ventilation and venting of the storage container via the hollow needle when liquid is transferred.
