  • Apparatus for filling cans with a liquid
    Patent number: 5119853
    Abstract: An apparatus for filling cans with a liquid such as beer or soft drinks. The filling machine includes a turntable having a surface to support a plurality of open top cans and a reservoir containing a liquid is spaced above the supporting surface. A plurality of filling heads are mounted on the reservoir and serve to dispense the liquid into the individual cans. Each filling head includes a spring loaded cylindrical tulip adapted to seal against the upper edge of the can and a vent tube and fill tube are disposed concentrically within the tulip. The lower end of the vent tube communicates with the can while the upper end is sealed against the surface of the reservoir and when the sealing engagement is released the vent tube communicates with the headspace of the reservoir. The lower end of the fill tube carries a valve that controls flow of liquid from the reservoir into the can.
