Abstract
In machines for filling bottles, liquid passes into a bottle past filling valve sealing sleeve and air exits through a vent tube; the filling valve retainer carries an annular rubber gasket that seals against the lip of the bottle to prevent leakage as the bottle fills; a centering bell is carried on the filling valve retainer and extends over the neck of the bottle; the sealing gasket is secured in the centering bell and the gasket is removed from the filling valve retainer by the removal from the retainer of the centering bell; the centering bell is held to the filling valve retainer by resilient snap-in means.
