ABSTRACT:
The device for the air-free filling in particular of flexible bags (1) under counterpressure consists of a filling pipe (5) which, with a sealing cone (9), can be guided into a filling and extraction connecting piece (2) of the bag. A filling valve (13) is provided in the direct proximity of the filling-pipe delivery orifice (4), which filling valve (13) is formed from a conical surface (15) of the filling-pipe inner wall (14) and a conical mating piece (18) which is provided on the end of a valve stem (17) which is guided in the filling pipe in axially movable manner.
The product to be filled flows into the filling-pipe inner space (20) through a product feed line, and, via a longitudinal bore (19) made in the valve stem, a vacuum can be applied or a protective gas and also a sterilizing agent can be fed at the area around the delivery orifice (4). This device permits a complete, procedural separation between the product feed to the flexible bag and the evacuating, gassing and sterilizing operations required before or after filling.
