ABSTRACT:
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.
