Patent ID: 8701720

Claim:
A unit ( 10 ) for filling containers ( 14 ), which comprises: an insulator ( 16 ) comprising an outer housing ( 18 ) provided with an inlet (E) and an outlet (S) through which the containers ( 14 ) are respectively introduced and evacuated downstream out of the housing ( 18 ), the housing ( 18 ) delimiting with an internal structure ( 20 ) a volume (V) forming an aseptic working area ( 22 ) comprising means ( 28 ) for insufflating sterile air which, arranged at the top part of the insulator ( 16 ), are able to insufflate a sterile air flow for creating an overpressure inside the volume (V), in which the insulator ( 16 ) comprises, in the bottom part, exhaust means ( 48 ), separate from the inlet (E) and from the outlet (S), intended to allow a controlled evacuation of the flow of insufflated sterile air, the means ( 28 ) for insufflating sterile air are adapted to insufflate a laminar flow (F) of insufflated sterile air and are arranged in a top part of the insulator ( 16 ) with a predetermined inclination so as to project the laminar flow (F) of sterile air toward an outer peripheral surface ( 44 ) of the containers ( 14 ) with an angle (α) which is defined by the intersection of a main axis (A) of the means for insufflation ( 28 ) with the main axis of the containers ( 14 ) which extend vertically in order to be filled.
