A hollow-needle assembly (9) is part of a transfer apparatus that serves for transferring a liquid between a storage container (2) and a further use container. The hollow-needle assembly (9) has a hollow needle (10) having a pointed needle end (15). A liquid duct (39) for transporting liquid through the hollow needle (10) and out of the latter leads out via at least one liquid-duct opening (41) in the region of the free needle end (15). An aeration gas duct (42) that likewise leads out via a gas-duct opening (43) in the region of the free needle end (15) serves for transporting gas through the hollow-needle assembly (9). Duct paths of the at least one liquid duct (39) and of the at least one aeration gas duct (42) extend separately from one another. The ducts (39, 42) lead out adjacently to one another axially along the hollow needle (10) 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 (10) extends between in each case one liquid-duct opening (41) and an adjacent gas-duct opening (43) in the circumferential direction. This results in reliable ventilation and venting of the storage container via the hollow needle when liquid is transferred.一中空針頭組件(9)係傳送設備的一部份，其具有用於在儲存容器(2)及另一個使用容器之間傳送液體的作用。該中空針頭組件(9)具有中空針頭(10)，該中空針頭具有尖銳的針頭端部(15)。用於運送液體經過該中空針頭(10)及離開該中空針頭之液體通道(39)經由該自由針頭端部(15)的區域中之至少一液體通道開口(41)引出。同樣地經由該自由針頭端部(15)的區域中之氣體通道開口(43)引出的通氣氣體通道(42)，具有用於運送氣體經過該中空針頭組件(9)之作用。該至少一液體通道(39)的通道路徑與該至少一通氣氣體通道(42)之通道路徑彼此分開地延伸。該等通道(39、42)沿著該中空針頭(10)彼此毗連軸向地引出，並以一方式於圓周方向中彼此偏置。在每一案例中，於該圓周方向中，在該中空針頭(10)之縱長方向中延伸的針頭分開邊緣延伸於一液體通道開口(41)及一鄰接的氣體通道開口(43)之間。當液體被傳送時，這導致該儲存容器經由該中空針頭的可靠通風及排氣。
