The invention relates to devices for transferring, without the risk of contamination, products flowing out under gravity from an upper receptacle (1) or pipe (43) towards a lower receptacle (1) or pipe (16). The device [according to the invention]includes a hermetic enclosure (19, 45) covering the orifice (18, 44) of one of the receptacles or pipes (16, 43), it being possible for the mouth of the orifice (5, 11) of the other receptacle (1) or pipe to be inserted therein, this other receptacle (1) or pipe [includes closing-off means]including a flange (10, 14) capable of closing the enclosure (19, 45) when the mouth of the other receptacle is inserted therein so that a flow of inert gas can be driven through the inside volume of the hermetic enclosure (19, 14) preventing cross-contamination between the content of the receptacle (1) or pipe (43) and the ambient atmosphere. The device is particularly applicable to the transfer of hormonal, sterile, toxic products, to cytostatic products, and even to explosive mixtures.

A device for transferring, without contamination, products flowing out under gravity from an upper receptacle including a lower orifice, the mouth of which points downwards, towards a lower pipe situated at a lower level than the upper receptacle and including an upper orifice, the mouth of which points upwards, wherein each orifice of said upper receptacle and lower pipe is closed off by a moveable cover, the said device being comprised of: a hermetic enclosure defining an inside volume and surrounding the orifice of said lower pipe, and including an access opening shaped such that the mouth of the orifice of the upper receptacle is insertable therein; first closing-off means for closing said access opening and isolating the inside volume of the enclosure with respect to the ambient atmosphere when said upper receptacle is not inserted therein, and actuating means for opening said first closing-off means such that said upper receptacle is capable of being inserted therein; second closing-off means for isolating the inside volume of the enclosure with respect to the ambient atmosphere when the mouth of said upper receptacle is inserted therein; means capable of opening the respective covers of the upper receptacle and lower pipe when their orifices are facing each other and when the enclosure is isolated from the ambient atmosphere by the second closing-off means; means for injecting a flow of gas into the inside volume of the enclosure surrounding the respective mouths of the upper receptacle and lower pipe; and, means connected to the inside volume of the enclosure for sucking up the flow of gas.
