Patent ID: 8387668

Claim:
A container filling machine for filling containers comprising at least one filling station comprising a filling spout connected to filling liquid storage means; and a 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; and displacement 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, and wherein each collecting member includes a lateral evacuation duct opening into an internal space of the collecting member located above the deformation chamber.
