Abstract: A machine for filling containers includes a series of filling stations, each of which is equipped with an impervious chamber for receiving a container to be filled. The chamber is opened in order to load or unload the container and closed in order to control the atmosphere in the chamber during the filling process. The chamber is delimited by an upper head section, which has a filling spout, by an essentially cylindrical lateral wall and by a base wall. The filling machine has element for modifying the volume of the closed chamber.

Abstract: A filling machine including at least one filling tube (22), whereby a product flows through said filling tube and said filling tube is placed opposite the opening of a receptacle that is to be filled. The feed for the filling tube is controlled by a valve (30) which is arranged in a downward skewed position in relation to the tube and the valve is joined to the tube by a feed pipe (28).

Abstract: A filling machine (38) includes at least one filling tube (22), whereby a product flows through the tube, which tube is placed opposite the opening of a receptacle (12) that is to be filled. The filling tube is accommodated in a fixed housing that is joined to a support (34) for the filling tube; the housing possesses an orifice (48) whereby the filling tube is placed opposite thereto and the housing also includes a moveable obturating flap (50) that closes the orifice and seals the housing when in a closed position. The machine includes structure that enables a cleaning agent to be circulated inside the housing.

Abstract: A flowback method for a product contained in the distribution circuit of a filling machine. The distribution circuit (22, 24, 26, 28, 30) creates an upstream/downstream link between a storage tank for said product and a filling tube (22) that is placed opposite the opening of a receptacle (12) that is to be filled. The method includes a step whereby a closed area around the filling tube (22) is defined by a sealed housing (38). The method further includes a step whereby a circulating liquid is injected into the above-mentioned area under pressure. The liquid passes through an auxiliary port (70), whereupon the product contained in the distribution method (22, 24, 26, 28, 30) flows back in the direction of the storage tank.

Abstract: A screw intended to be set in place and removed rapidly. The screw is characterized in that the threads are intended to take two positions: a first position wherein they project at the periphery of a body (1) and a second position wherein they are retracted into the thickness of the body (1). The screw further comprises a displacement member (27) intended to displace the threads from one position to the other and a device for locking the threads (29, 36, 27, 38) in the extended position.
