- 1. In an apparatus for filling open top cans with a liquid, comprising a supporting surface to support an open-top can, a filling head including a reservoir to contain a liquid and having a headspace above the liquid level in said reservoir, fill conduit means interconnecting said reservoir with said can for conducting liquid from said reservoir to said can, valve means associated with said fill conduit means for opening said fill conduit means to permit liquid to flow to said can, vent conduit means communicating between the open top of said can and the headspace of said reservoir for venting gas from said can as liquid is introduced into said can, and resilient means interconnecting said fill conduit means and said vent conduit means, said resilient means being constructed and arranged to permit downward movement of said vent conduit means when said valve means is in the closed position to thereby permit said vent conduit means to be lowered into the open top of said can independently of movement to said valve means.
- 2. The apparatus of claim 1, wherein said resilient means comprises a spring.
- 3. In an apparatus for filling open top cans with a liquid, comprising a supporting surface to support an open-top can, a filling head including a reservoir to contain a liquid and having a headspace above the liquid level in said reservoir, fill conduit means interconnecting said reservoir with said can for conducting liquid from said reservoir to said can, valve means associated with said fill conduit means for opening said fill conduit means to permit liquid to flow to said can, vent conduit means communicating between the open top of said can and the headspace of said reservoir for venting gas from said can as liquid is introduced into said can, means for mounting said vent conduit means for independent movement relative to said fill conduit means, and means for moving said vent conduit means relative to said fill conduit means when said valve means is in a closed position to locate the fill conduit means in a filling position in communication with the open top of the can.
- 4. The apparatus of claim 3, wherein said fill conduit means is disposed concentrically of said vent conduit means.
- 5. The apparatus of claim 3, and including biasing means for biasing said vent conduit means to an upper position relative to said fill conduit means.
