Abstract
In cleaning and sterilizing rotary backpressure filling machines which include filling elements and a pressure actuated conveyor operatively associated therewith, the conveyor is adapted to support rinsing vessels used in cleaning the filling elements. More particularly, the cleaning operation of is effected by inserting, fastening and detaching a rinsing vessel upon the filling machine with a rinsing operation occurring while the rinsing vessel is fastened to the machine. The rinsing vessel includes axially movable sleeve which cooperates with radially movable clamping members, preferably in the form of spherical balls, to attach the rinsing vessel to an air and/or gas fill pipe of the filling machine, with pressure being introduced into the rinsing vessel to actuate valve means enabling flow of cleansing fluid through the machine. The rinsing vessel is operatively supported upon the conveyor and the cycle of machine operation generally includes attachment of the rinsing vessel, performance of the cleansing operation and subsequent detachment of the rinsing vessel.
