Improvements relating to filling heads of filling machines for charging quantities of liquid into containers, and filling machines including such heads

摘要

Filling heads of filling machines for charging quantities of liquid into containers and filling machines including such heads, wherein there is a dispensing head which registers with the top of the container (52) to be filled, the container is raised to lift the discharge head, the liquid is dispensed into the container and the subsequent lowering of the discharge head when the container has been filled creates a partial vacuum effect in discharge passages (70) through which the liquid is dispensed to prevent dripping or flowing of residual liquid into the container.
