A container filling machine includes at least one filling spout, and a cleaning device including a stationary collecting member with a passage opening, a sealing member that can be displaced between a retracted position and a service position in which said sealing member is capable of tightly sealing the passage opening, and displacement means for displacing said sealing member between the retracted position and the service position thereof. The sealing member includes an elastically deformable membrane mounted on a holder and forming therewith a tight deformation chamber capable of receiving a pressurized fluid in order to deform the deformable membrane for sealing the passage opening when said holder is displaced into the service position by the displacement means.

1. A container filling machine for filling containers comprising at least one filling station comprising a filling spout connected to filling liquid storage means; anda cleaning device comprising, for each filling station, a stationary collecting member surrounding the discharge opening of the filling spout and exhibiting a passage opening for a bottle neck during filling operations arranged below the discharge opening of the filling spout,a sealing member displaceable between a retracted position wherein said sealing member is spaced apart from the filling spout, to allow for the filling of a container placed under the filling spout, and a service position wherein said sealing member is capable of tightly sealing and closing the passage opening of the collecting member to carry out cleaning operations; anddisplacement means for displacing said sealing member between its service position and its retracted position,the sealing member comprising an elastically deformable membrane mounted on a holder and forming therewith a tight deformation chamber capable of receiving a pressurized fluid in order to deform the deformable membrane to ensure the sealing and closing of the passage opening when said holder is brought to the service position by the displacement means, a diameter of the sealing member being higher than a diameter of the passage opening of the collecting member and the collecting member formed of a substantially cylindrical skirt made in one block with the filling spout, andwherein each collecting member includes a lateral evacuation duct opening into an internal space of the collecting member located above the deformation chamber. 2. The machine according to claim 1, the deformable membrane being mounted on the upper surface of a holder plate, said holder plate being fitted with a supply channel opening under the deformable membrane, and capable of being supplied with pressurized fluid. 3. The machine according to claim 2, wherein the deformable membrane is mounted in a recess of said holder plate, by means of a mounting flange, said membrane exhibiting a peripheral ridge housed in a corresponding groove of the recess. 4. The machine according to claim 1, wherein the collecting member presents a lower edge defining the passage opening, said deformable membrane being capable of pressing against said lower edge during the pressurizing of the deformation chamber. 5. A container filling machine for filling containers comprising: at least one filling station comprising a filling spout connected to filling liquid storage means, anda cleaning device comprising, for each filling station, a stationary collecting member surrounding the discharge opening of the filling spout and exhibiting a passage opening for a bottle neck during filling operations arranged below the discharge opening of the filling spout,a sealing member displaceable between a retracted position wherein said sealing member is spaced apart from the filling spout, to allow for the filling of a container placed under the filling spout, and a service position wherein said sealing member is capable of tightly sealing and closing the passage opening of the collecting member to carry out cleaning operations; anddisplacement means for displacing said sealing member between its service position and its retracted position,the sealing member comprising an elastically deformable membrane mounted on a holder and forming therewith a tight deformation chamber capable of receiving a pressurized fluid in order to deform the deformable membrane to ensure the sealing and closing of the passage opening when said holder is brought to the service position by the displacement means,wherein the displacement means are capable of displacing the holder of the deformable membrane from its retracted position to its service position through at least one downward vertical translation displacement, parallel to the longitudinal axis of the filling spout, followed by a horizontal displacement, perpendicularly to the longitudinal axis of the filling spout, such that the deformable membrane is substantially centered according to the longitudinal axis of the spout. 6. The machine according to claim 5, wherein the horizontal displacement is followed by an upward vertical translation displacement substantially according to the longitudinal axis of the filling spout to bring the holder of the deformable membrane to the service position. 7. The machine according to claim 5, including a plurality of filling stations, wherein the deformable membranes on their holder in their retracted position are arranged between the filling spouts. 8. The machine according to claim 7, the holders of the deformable membranes are simultaneously displaced between their retracted position and their service position by joint displacement means. 9. The machine according to claim 8, the machine being of a rotary type, said filling stations being arranged at regular angular spaces under a rotary holder, the deformable membranes on their holders are mounted at regular angular spaces on a ring assembled under said rotary holder via vertical translation and rotation displacement means, said horizontal displacement consisting of a rotation around the rotational axis of the rotary support, at an angle corresponding to half a pitch between two successive filling spouts. 10. The machine according to claim 9, the holders of the deformable membranes are formed of an annular holder plate assembled to the ring, said holder plate being fitted with openings between the deformable membranes to allow for the passage of the filling spouts equipped with their collecting member in the retracted position of the holder plate. 11. The machine according to claim 9, wherein the ring internally bears said holder plate and is fitted with at least two mounting legs extending radially outwards, each leg being assembled by a vertical jack on a carriage that is slidingly mounted on a horizontal guiding rail secured to the rotary holder, at least one jack mounted between the rotary holder and a carriage ensuring the rotational displacement of the ring. 12. The machine according to claim 9, including centering means for centering the ring in the retracted position and in the service position. 13. The machine according to claim 1, each filling station comprising holder means for holding a container comprising at least one holding member capable of cooperating with the neck of a container, said deformable membrane on the holder passing between said holding member and the collecting member. 14. The machine according to claim 1, wherein the container filling machine has a vertical axis and the lateral evacuation duct is radially arranged with respect to said vertical axis.
